Item 1.	Business
 
We are a biopharmaceutical company focused on the development and commercialization of recombinant therapeutic proteins based on our proprietary ProCellEx ®  protein expression system, or ProCellEx. Using our ProCellEx system, we are developing a pipeline of proprietary, biobetter and biosimilar versions of recombinant therapeutic proteins, based on our plant cell-based expression technology, that primarily target large, established pharmaceutical markets and that rely upon known biological mechanisms of action. Our initial commercial focus has been on complex therapeutic proteins, including proteins for the treatment of genetic disorders, such as Gaucher disease and Fabry disease. We believe ProCellEx will enable us to develop proprietary recombinant proteins that are therapeutically equivalent or superior to existing recombinant proteins currently marketed for the same indications. Because we are primarily targeting biologically equivalent versions of highly active, well-tolerated and commercially successful therapeutic proteins, we believe our development process is associated with relatively less risk compared to other biopharmaceutical development processes for completely novel therapeutic proteins. We are now also applying the unique properties of our ProCellEx system for the oral delivery of therapeutic proteins, with the first two product candidates being glucocerebrosidase and antiTNF fusion protein.
 
The following table summarizes our current product and product candidates and their respective stages of development as of December 31, 2013.

 
On May 1, 2012, the U.S. Food and Drug Administration, or the FDA, approved for sale our first commercial product, taliglucerase alfa for injection, which is being marketed in the United States and Israel under the brand name ELELYSO TM , as an enzyme replacement therapy, or ERT, for the long-term treatment of adult patients with a confirmed diagnosis of type 1 Gaucher disease. Subsequently, taliglucerase alfa was approved by the Brazilian National Health Surveillance Agency (Agencia Nacional de Vigilancia Sanitaria, or ANVISA) in March 2013, by the Israeli Ministry of Health, or the Israeli MOH, in September 2012, and by the applicable regulatory authorities in Uruguay, Mexico and Chile. Taliglucerase alfa will be marketed under the name UPLYSO TM  in Brazil and certain other Latin American countries. Taliglucerase alfa is our proprietary, recombinant form of glucocerebrosidase, or GCD, that is produced or expressed through ProCellEx. Taliglucerase alfa is the first plant cell-based recombinant therapeutic protein to be approved by the FDA or by the regulatory authorities with jurisdiction over any substantial market. Gaucher disease is a rare and serious lysosomal storage disorder with severe and debilitating symptoms. Gaucher patients suffer from mutations in or deficiencies of GCD, an enzyme that is naturally found in human cells.
 
Since May 2012, taliglucerase alfa has been marketed in the United States by Pfizer Inc., or Pfizer, our commercialization partner, as provided in the exclusive license and supply agreement by and between Protalix Ltd., our wholly-owned subsidiary, and Pfizer, which we refer to as the Pfizer Agreement. We granted Pfizer an exclusive, worldwide license to develop and commercialize taliglucerase alfa under the Pfizer Agreement, but we retained those rights in Israel and in Brazil. We have agreed to a specific allocation between Protalix Ltd. and Pfizer of the responsibilities for the continued development efforts for taliglucerase alfa outside of Israel. Since 2013, taliglucerase alfa has been marketed in Israel by Protalix Ltd.

On June 18, 2013, we entered into a Supply and Technology Transfer Agreement, or the Brazil Agreement, with Fiocruz, for taliglucerase alfa. The agreement became effective in January 2014. The technology transfer is designed to be completed in four stages and is intended to transfer to Fiocruz the capacity and skills required for the Brazilian government to construct its own manufacturing facility, at its sole expense, and to produce a sustainable, high-quality, and cost-effective supply of taliglucerase alfa. The initial term of the technology transfer is seven years. Under the agreement, Fiocruz has committed to purchase at least approximately $40 million worth of taliglucerase alfa during the first two years of the term. In subsequent years, Fiocruz is required to purchase at least approximately $40 million worth of taliglucerase alfa per year. Additionally, we are not required to complete the final stage of the technology transfer until Fiocruz purchases at least approximately $280 million worth of taliglucerase alfa.
 
We are cooperating with Pfizer to obtain marketing approval for taliglucerase alfa in additional countries and jurisdictions. In addition to those countries in which taliglucerase alfa has been approved, marketing authorization applications have been filed in other countries.
 
In December 2012, we entered into a Clinical Development Agreement with Pfizer under which we will continue to manage, administer and sponsor current, ongoing clinical trials relating to ELELYSO. We are currently sponsoring extension studies of ELELYSO in adult and pediatric patients. New clinical trials for ELELYSO, if it is elected that any such clinical trial be performed, will be conducted and sponsored by Pfizer. Under the terms of the agreement, we were eligible to receive a payment of $8.3 million upon the achievement of certain near-term clinical development goals. The goals were achieved prior to the end of fiscal year 2012 and the $8.3 million payment has been paid in full. This agreement helps to maintain the continuity of the ongoing clinical trials for Gaucher patients and physicians and reinforces the companies’ mutual commitment to the Gaucher community.
 
We performed a number of studies on taliglucerase alfa to supplement the pivotal phase III clinical trial, which we completed in September 2009. We initiated a double-blind, follow-on extension study in 2008 which consisted of eligible patients who had completed nine months of treatment in the pivotal phase III clinical trial. The patients were offered the opportunity to continue to receive taliglucerase alfa at the same dose they received in the pivotal trial for an additional 15 months in a blinded manner. We also conducted a nine-month, worldwide, multi-center, open-label, switch-over clinical study evaluating the safety and efficacy of switching Gaucher patients currently treated with Cerezyme ® , which is produced by Genzyme Corporation, or Genzyme (a Sanofi company), with taliglucerase alfa, which was successfully completed in 2011. We also conducted a 12-month clinical trial of naïve and switchover pediatric patients, which was successfully completed in 2012. Based on the data from this study, an application for a supplement to the NDA for ELEYSO, allowing a pediatric use indication to be added to the product label, has recently been submitted by Pfizer to the FDA. Patients in the extension trials are still being treated with taliglucerase alfa.
 
Currently, patients are being treated with taliglucerase alfa on a commercial basis in the United States, Brazil, Israel and Chile. Globally, patients are being treated through our extension trials and related studies, compassionate use programs, special access agreements, named patient provisions and other programs designed to ensure that treatments are available to Gaucher patients in light of recent shortages of approved treatments. In France, Gaucher patients are being treated with taliglucerase alfa through an Autorisation Temporaire d’Utilisation (ATU), or Temporary Authorization for Use, a regulatory mechanism used by the French Health Products and Safety Agency to make non-approved drugs available to patients in France when a genuine public health need exists. In addition to the United States and France, taliglucerase alfa is currently being provided to Gaucher patients under special access agreements or named patient provisions in Brazil and in other countries. Hundreds of patients, in the aggregate, have been treated with taliglucerase alfa.
 
In addition to taliglucerase alfa, we are developing an innovative product pipeline using our ProCellEx protein expression system. Our product pipeline currently includes, among other candidates: PRX-102, a therapeutic protein candidate for the treatment of Fabry disease; PRX-112, an orally administered glucocerebrosidase enzyme for the treatment of Gaucher patients utilizing oral delivery of the recombinant GCD enzyme produced and encapsulated within carrot cells; PRX-106, an oral antiTNF, a plant cell expressed recombinant fusion protein combined of the binding domain of the human TNF receptor (TNFR) and an antibody portion, which is being developed for the treatment of certain immune and inflammatory diseases, such as rheumatoid arthritis, colitis, Crohn’s disease, psoriasis and other autoimmune and inflammatory disorders; PRX-110, a proprietary plant cell recombinant human Deoxyribonuclease 1 under development for the treatment of Cystic Fibrosis, to be administered by inhalation; PRX-107, a proprietary plant cell recombinant human Alpha1-antitrypsin, or AAT, and others.
 
Except for the rights to commercialize taliglucerase alfa worldwide (other than Brazil and Israel), which we licensed to Pfizer, we hold the worldwide commercialization rights to all of our proprietary development candidates. We have built an internal marketing team designed to serve the Israeli market for taliglucerase alfa and we intend to establish internal commercialization and marketing teams for our other product candidates in North America, the European Union and in other significant markets, including Israel, subject to required marketing approvals, as the need arises. In addition, we continuously evaluate potential strategic marketing partnerships as well as collaboration programs with biotechnology and pharmaceutical companies and academic research institutes.

Industry Overview
 
Recombinant proteins have revolutionized the treatment of a variety of diseases and disorders. Recombinant proteins are forms of human proteins that are produced, or expressed, using a mammalian, plant, bacterial or yeast cell as a production engine. In the early 1970s, a number of key scientific breakthroughs, including, among others, the demonstration of genetic engineering and genetic sequencing techniques, as well as the synthesis of genes, led to the advancement of recombinant protein technology. As a result, the market for pharmaceutical therapeutics has undergone a transformation as recombinant proteins and other biologic products have become an increasingly significant portion of the global drug market and the focus of research worldwide. The IMS Institute for Healthcare Informatics reports that global biologic spending was $157 billion in 2010 (Report by the IMS Institute for Healthcare Informatics, July 2012).
 
Mammalian cell-based systems are the current industry standard for expression of recombinant therapeutic glycoproteins (complex proteins that contain sugar residues), including catalytic enzymes and monoclonal antibodies. Mammalian cell-based systems were first introduced in the late 1980s and are currently used to produce many of the biotechnology industry’s largest and most successful therapeutic proteins, including Epogen ® , Neupogen ® , Cerezyme, Rituxan ® , Enbrel, Neulasta ® , Remicade and Herceptin ® . Mammalian cell-based expression technology is based on the introduction of a human gene encoding for a specific therapeutic protein into the genome of a mammalian cell. The cells most often used in connection with mammalian cell-based protein expression are Chinese hamster ovary (CHO) cells.
 
Mammalian cell-based expression systems have become the dominant system for the expression of recombinant proteins due to their capacity for sophisticated, proper protein folding (which is necessary for proteins to carry out their intended biological activity), assembly and post-expression modification, such as glycosilation (the addition of sugar residues to a protein which is necessary to enable specific biological activity by the protein). While bacterial and yeast cell-based expression systems were the first protein expression systems developed by the biotechnology industry and remain cost-effective compared to mammalian cell-based production methodologies, proteins expressed in bacterial and yeast cell-based systems lack the capacity for sophisticated protein folding, assembly and post-expression modifications, which are key factors of mammalian cell-based systems. Accordingly, such systems cannot be used to produce glycoproteins or other complex proteins and, therefore, bacterial and yeast cell-based systems are limited to the expression of the most basic, simple proteins, such as insulin and growth hormones. Due to their significant advantages, mammalian cell-based expression systems can produce proteins with superior quality and efficacy compared to proteins expressed in bacteria and yeast cell-based systems. As a result, the majority of currently approved therapeutic proteins, as well as those under development, are produced in mammalian cell-based systems.
 
Despite the utility and widespread use of mammalian cell-based systems, they are subject to a number of disadvantages. CHO cells and other mammalian cells are highly sensitive and can only be grown under near perfect conditions, requiring highly complex, expensive, stainless steel bioreactors which tightly regulate the required temperature, pH and oxygen levels. As a result, such bioreactor systems are very costly and complicated to operate. CHO cells and other mammalian cells are also susceptible to viral infections, including human viruses, and several cases of viral contamination have occurred recently. The FDA and other regulatory authorities require viral inactivation and other rigorous and detailed procedures for mammalian cell-based manufacturing processes in order to address these potential hazards, thereby increasing the cost and time demands of such expression systems. Furthermore, the current FDA and other procedures only ensure screening for scientifically identified, known viruses. Accordingly, compliance with current FDA and other procedures does not fully guarantee that patients are protected against transmission of unknown or new potentially fatal viruses that may infect mammalian cells. In addition, mammalian cell-based expression systems require large quantities of sophisticated and expensive growth medium to accelerate the expression process.
 
Several companies and research institutions have explored alternatives to mammalian cell-based production technologies that overcome some of these disadvantages, focusing primarily on the expression of human proteins in genetically-modified organisms, or GMOs, such as transgenic field-grown, whole plants and transgenic animals. However, these alternate techniques may be restricted by regulatory and environmental risks regarding contamination of agricultural crops and by the difficulty in applying cGMP standards of the pharmaceutical industry to these expression technologies and none of these technologies have been approved by the regulatory agencies with jurisdiction over any substantial market.

ProCellEx: Our Proprietary Protein Expression System
 
ProCellEx is our proprietary production system. We have developed ProCellEx based on our plant cell culture technology for the development, expression and manufacture of recombinant proteins. ProCellEx consists of a comprehensive set of capabilities and proprietary technologies, including advanced genetic engineering and plant cell culture technology, which enables us to produce complex, proprietary and biologically equivalent proteins for a variety of human diseases. This protein expression system facilitates the creation and selection of high expressing, genetically stable cell lines capable of expressing recombinant proteins. The entire protein expression process, from initial nucleotide cloning to large-scale production of the protein product, occurs under cGMP-compliant, controlled processes. Our plant cell culture technology uses plant cells, such as carrot and tobacco cells, which undergo advanced genetic engineering and are grown on an industrial scale in a flexible bioreactor system. Cell growth, from scale up through large-scale production, takes place in flexible, sterile, polyethylene bioreactors which are confined to a clean-room environment. Our bioreactors are well-suited for plant cell growth using a simple, inexpensive, chemically-defined growth medium as a catalyst for growth. The reactors are custom-designed and optimized for plant cell cultures, easy to use, entail low initial capital investment, are rapidly scalable at a low cost and require less hands-on maintenance between cycles. Our protein expression system does not involve mammalian or animal components or transgenic field-grown, whole plants at any point in the production process. As a result, through our ProCellEx protein expression system, we believe that we can develop recombinant therapeutic proteins yielding substantial cost advantages, accelerated development and other competitive benefits when compared to mammalian cell-based protein expression systems.
 
Our ProCellEx system is capable of producing proteins with an amino acid sequence and three dimensional structure practically equivalent to that of the desired human protein, and with a very similar, although not identical, glycan, or sugar, structure, as demonstrated in our internal research and external laboratory studies. In collaboration with the Weizmann Institute of Science, we have demonstrated that the three-dimensional structure of a protein expressed in our proprietary plant cell-based expression system retains the same three-dimensional structure as exhibited by the mammalian cell-based expressed version of the same protein. In addition, proteins produced by our ProCellEx system maintain the biological activity that characterize that of the naturally-produced proteins. Based on these results, we believe that proteins developed using our ProCellEx protein expression system have the intended composition and correct biological activity of their human equivalent proteins.
 
We believe that the ProCellEx system will enable us, in certain cases, to develop and commercialize recombinant proteins without infringing upon the method-based patents or other intellectual property rights of third parties. The major elements of our ProCellEx system are patent protected in most major countries. Moreover, we expect to enjoy method-based patent protection for the proteins we develop using our proprietary ProCellEx protein expression technology, although there can be no assurance that any such patents will be granted. In some cases, we may be able to obtain patent protection for the compositions of the proteins themselves. We have filed for United States and international composition of matter patents for taliglucerase alfa.
 
We have successfully demonstrated the feasibility of our ProCellEx system through: the FDA’s approval of taliglucerase alfa; the clinical and preclinical studies we have performed to date, including the positive efficacy and safety data in our phase III study of taliglucerase alfa, our switchover study and our extension study; preclinical results in well-known models in our enzyme for each of Fabry disease and pr-antiTNF; extensive animal studies for our PRX 106 enzyme; and by expressing, on an exploratory, research scale, many additional complex therapeutic proteins belonging to different drug classes, such as enzymes, hormones, monoclonal antibodies, cytokines and vaccines. The therapeutic proteins we have expressed to date in research models have produced the intended composition and similar biological activity compared to their respective human-equivalent proteins. Moreover, several of such proteins demonstrated advantageous biological activity when compared to the biotherapeutics currently available in the market to treat the applicable disease or disorder. We believe that the FDA’s approval of taliglucerase alfa represents a strong proof-of-concept of our ProCellEx system and plant cell-based protein expression technology. We also believe that the significant benefits of our ProCellEx system, if further substantiated in clinical trials and in the successful commercialization of taliglucerase alfa and our other product candidates, have the potential to transform the industry standard for the development of complex therapeutic proteins.
 
We are also using our ProCellEx system to produce active recombinant proteins systemically through oral administration of plant cells expressing biotherapeutic proteins. In such method, an enzyme is naturally encapsulated within carrot cells genetically engineered to express the targeted enzyme. Plant cells have the unique attribute of a cellulose cell wall which makes them resistant to enzyme degradation when passing through the digestive tract. The plant cell itself serves as a delivery vehicle, once released and absorbed, to transport the enzyme in active form to the bloodstream. With initial proof of concept now demonstrated, this would be the first time an enzyme will be administered orally rather than through intravenous therapy. To date we have completed successful preclinical animal studies for oral GCD and oral anti TNF, and a phase I clinical trial of oral GCD in Gaucher patients.

To date, our manufacturing facility, in which we utilize our ProCellEx system, was determined to be acceptable by each of the FDA, EMA, ANVISA, the Israeli MOH, the Australian Therapeutic Goods Administration, or the TGA, and Health Canada, after GMP inspections were performed as part of their respective reviews for marketing approval of taliglucerase alfa.
 
Competitive Advantages of Our ProCellEx Protein Expression System
 
We believe that our ProCellEx protein expression system, including our advanced genetic engineering technology and plant cell-based protein expression methods, affords us a number of significant advantages over mammalian, bacterial, yeast and transgenic cell-based expression technologies, including the following:
 
Ability to Penetrate Certain Patent-Protected Markets. We seek to develop recombinant proteins that we believe we can produce and commercialize without infringing upon the method-based patents or other intellectual property rights of third parties. Certain biotherapeutic proteins available for commercial sale are not protected by patents that cover the compound and are available for use in the public domain. Rather, the process of expressing the protein product in mammalian or bacterial cell systems is protected by method-based patents. Using our plant cell-based protein expression technology, we are able to express an equivalent protein without infringing upon these method-based patents. Moreover, we expect to enjoy method-based patent protection for the proteins we develop using our proprietary ProCellEx protein expression technology, although there can be no assurance that any such patents will be granted. In some cases, we may be able to obtain patent protection for the compositions of the proteins themselves. We have filed for United States and international composition of matter patents for taliglucerase alfa, PRX-102 and certain of our other product candidates.
 
Significantly Lower Capital and Production Costs. Plant cells have a number of dynamic qualities that make them well-suited for the production of therapeutic proteins. Plant cells grow rapidly under a variety of conditions and are not as sensitive to temperature, pH and oxygen levels as are mammalian cells. Our ProCellEx system, therefore, requires significantly less upfront capital expenditures as it does not use the highly complex, expensive, stainless steel bioreactors typically used in mammalian cell-based production systems to maintain very specific temperature, pH and oxygen levels. Instead, we use simple polyethylene bioreactors that can be maintained at the room temperature of the clean-room in which they are placed. This system also reduces ongoing production and monitoring costs typically associated with mammalian cell-based expression technologies. Furthermore, while mammalian cell-based systems require very costly growth media at various stages of the production process to achieve target yields of proteins, plant cells require only simple and much less expensive solutions based on sugar, water and microelements at infrequent intervals to achieve target yields. We believe that these factors will potentially result in lower capital and production costs for the commercial scale production of proteins by our ProCellEx system thereby providing us with a competitive advantage over competing protein expression technologies.
 
Elimination of the Risk of Viral Transmission or Infection by Mammalian Components. By nature, plant cells do not carry the risk of infection by human or other animal viruses. As a result, the risk of contamination of our products under development and the potential risk of viral transmission from our products and product candidates to future patients, whether from known or unknown mammalian viruses, is eliminated. Because our products and product candidates do not bear the risk of mammalian viral transmission, we are not required by the FDA or other regulatory authorities to perform the constant monitoring procedures for mammalian viruses during the protein expression process that are required in mammalian cell-based production. In addition, the production process of our ProCellEx system is void of any mammalian components which are susceptible to the transmission of prions, such as those related to bovine spongiform encephalopathy (commonly known as “mad-cow disease”). These factors further reduce the risks and operating costs of our ProCellEx system compared to mammalian cell-based expression systems.
 
Efficient Production Relative to Mammalian Based Systems. Our ProCellEx protein expression system produces enzymes which have uniform glycosilation patterns and therefore do not require the lengthy and expensive post-expression modifications that are required for certain proteins produced by mammalian cell-based systems, including the proteins for the treatment of Gaucher disease. Such post-expression modifications in mammalian cell-produced proteins are made in order to expose the terminal mannose sugar residues, which are structures on a protein that are key elements in allowing the expressed protein to bind to a target cell and subsequently be taken into the target cell for therapeutic benefit. For example, in the production of Cerezyme, exposing these terminal mannose sugar residues involves a multitude of highly technical steps which add time and cost to the production process. In addition, these steps do not guarantee the exposure of all of the required terminal mannose sugar residues, resulting in potentially lower effective yields and inconsistency in potency from batch to batch. Our ProCellEx protein expression system, by contrast, produces taliglucerase alfa in a “ready to use” form that does not require additional glycosilation or other modifications to make taliglucerase alfa suitable for use as an ERT for Gaucher disease. We believe this quality increases the potency and consistency of the expressed proteins, and thus, the effectiveness of the protein which presents an additional cost advantage of ProCellEx over competing protein expression methodologies.

Broad Range of Expression Capabilities. Our ProCellEx protein expression system is able to produce a broad array of complex glycosilated proteins, which differentiates our system from bacterial and yeast cell-based systems which are unable to produce complex proteins. We have successfully demonstrated the feasibility of our ProCellEx system by producing, on an exploratory, research scale, a variety of therapeutic proteins belonging to different classes of recombinant drugs, such as enzymes, hormones, monoclonal antibodies, cytokines and vaccines. We have demonstrated that the recombinant proteins we have expressed to date have the intended composition and correct biological activity of their human-equivalent protein, with several of such proteins demonstrating advantageous biological activity compared to the currently available biotherapeutics. In specific cases, we have been successful in expressing proteins that have not been successfully expressed in other production systems.
 
Potential ability to administer active therapeutic enzymes orally. We are using our ProCellEx system to produce active recombinant proteins systemically through oral administration of plant cells expressing biotherapeutic proteins. Plant cells have the unique attribute of a cellulose cell wall which makes them resistant to enzyme degradation when passing through the digestive tract. The plant cell itself serves as a delivery vehicle, once released and absorbed, to transport the enzyme in active form to the bloodstream. If proven effective, this would be the first time an enzyme will be administered orally rather than through intravenous therapy. To date we have completed successful preclinical animal studies for oral GCD and oral anti TNF, and a phase I clinical trial of oral GCD in Gaucher patients.
 
Our Strategy
 
Our goal is to become a leading fully integrated biopharmaceutical company focused on the development and commercialization of proprietary biobetter and biosimilar versions of recombinant therapeutic proteins. To achieve our goal, we intend to:
 
Commercialization of ELELYSO in Israel/UPLYSO in Brazil. We intend to maximize our supply and technology agreement in Brazil to potentially generate significant revenues in the territory for which we own the rights. We also intend to continue to work closely with the Israeli HMOs to increase our revenues in our home country.
 
Facilitate the successful development and commercialization of ELELYSO by Pfizer. We intend to work closely with our commercialization partner, Pfizer, to continue to develop and to commercialize ELELYSO. We have facilitated relationships between Pfizer and the Gaucher community and third-party payors.
 
Obtain Regulatory Approval for ELEYSO for the Treatment of Gaucher Disease. ELELYSO has been approved for marketing in the United States, Israel, Brazil, Uruguay, Mexico and Chile. In addition, Pfizer has submitted marketing applications to the regulatory authorities of other countries.
 
Establish Development and Commercialization Alliances with Corporate Partners. We believe that our technology and know-how has broad applicability to many classes of proteins and can be used to develop and potentially enhance numerous existing marketed protein therapeutics. We continuously review a broad array of product partnering, technology sharing and other strategic alternatives and expect that such transactions will facilitate the leveraging of our technology and know-how to optimize our resources and effectively penetrate a wider range of target diseases and therapeutic markets.
 
Develop PRX-102 and Oral Glucocerebrosidase. In December 2012, the first patient was treated in our phase I/II clinical trial of Fabry patients with PRX-102 and, in February 2014 we reported phase I clinical trial results for our phase I clinical trial of Oral GCD in Gaucher patients, including patients with low platelet counts, at the Lysosomal Storage Disease Network WORLD Symposium (LDN WORLD). We expect to initiate next phase clinical trial of Oral GCD in the second half of 2014.
 
Develop a Pipeline of Innovative and Biosimilar Versions of Recombinant Therapeutic Proteins. We are leveraging our ProCellEx protein expression system to develop a pipeline of innovative or biosimilar versions of recombinant proteins, with an emphasis on therapeutic treatments with large market opportunities. We select additional therapeutic candidates for development through in-house testing, licensing agreements with academic institutions and collaborations with pharmaceutical partners. We have currently identified several product candidates that are mainly oriented towards the specialty disease and therapeutic market segments, including PRX-102, our product candidate for Fabry disease, and our orally-administered glucocerebrosidase enzyme. We have also identified several other product candidates that are chemical equivalents of approved therapeutic products that will no longer be patent protected within the next couple of years, such as oral-antiTNF, our proprietary product candidate for the treatment of certain immune diseases such as rheumatoid arthritis, colitis, Crohn’s disease, psoriasis and other autoimmune and inflammatory disorders. In addition, we have a number of other proteins in different stages of research and development in our pipeline. We believe our cost-effective technology will be an important asset for the commercialization of such drug candidates. We believe that the clinical and regulatory pathway for many of our pipeline product programs candidates is already established, which may reduce the risks and costs associated with our clinical development programs. Furthermore, established markets already exist for the development of most of our current product candidates.

Collaborate with Third Party Pharmaceutical Companies and Build a Targeted Sales and Marketing Infrastructure. We have licensed to Pfizer the right to commercialize ELELYSO worldwide, except in Israel and Brazil. We have built our own, internal marketing team designed to serve the Israeli market for ELELYSO and we intend to establish similar sales and marketing capabilities for our other product candidates in North America, the European Union and in other significant markets, including Israel. We believe that the focus of our current clinical pipeline mainly on relatively rare genetic disorders with small patient populations and a highly concentrated group of physicians focused on treating patients with such disorders will facilitate our creation of a targeted internal sales force. In addition we are continuously evaluating potential strategic marketing partnerships with respect to our other product candidates.
 
Acquire or In-License New Technologies, Products or Companies. We continuously seek attractive product candidates and innovative technologies to in-license or acquire. We intend to focus on product candidates that would be synergistic with our ProCellEx protein expression system and expertise and that represent large potential market opportunities. We believe that by pursuing selective acquisitions of technologies in businesses that complement our own, we will be able to enhance our competitiveness and strengthen our market position. We are evaluating several such products, and we engaged in confidential discussions with a number of academic and medical institutes for these matters.
 
Leverage Strength and Experience of Our Management Team and Board of Directors. Our management team has extensive experience in the biotechnology and pharmaceutical industry. Our director, Professor Roger D. Kornberg, who heads our Scientific Advisory Board, is a renowned biochemist and laureate of the Nobel Prize in Chemistry. We intend to continue to leverage their experience and established track record as well as their relationships across the biotechnology and pharmaceutical industries.
 
Leverage Our ProCellEx System to Potentially Enable the Oral Administration of Active Therapeutic Enzymes. Plant cells have the unique attribute of a cellulose cell wall which makes them resistant to enzyme degradation when passing through the digestive tract. The plant cell itself serves as a delivery vehicle, once released and absorbed, to transport the enzyme in active form to the bloodstream. We intend to explore additional therapeutic indications which can be produced through our proprietary technology.
 
ELELYSO, Our First Commercial Product
 
ELELYSO (taliglucerase alfa), our first commercial product, is a plant cell expressed recombinant glucocerebrosidase enzyme (GCD) for the treatment of Gaucher disease. On May 1, 2012, the FDA approved ELELYSO for injection as an enzyme replacement therapy (ERT) for the long-term treatment of adult patients with a confirmed diagnosis of type 1 Gaucher disease. It was subsequently approved by the Israeli MOH in September 2012, the Brazilian National Health Surveillance Agency (ANVISA) in March 2013, the Mexican Federal Commission for the Protection against Sanitary Risk (COFEPRIS) in April 2013 and the regulatory authorities of other countries.
 
We believe that taliglucerase alfa has the potential to offer patients and healthcare payors a more effective and cost efficient treatment of Gaucher disease compared to the currently available ERTs.
 
Although Gaucher disease is a relatively rare disease, it represents a substantial commercial market due to the severity of the symptoms and the chronic nature of the disease. We believe that the approval of taliglucerase alfa as a treatment for Gaucher disease with its potentially longer acting profile and more cost-effective development process, may lead to an increase in the number of patients who will be able to have access to and afford such treatment, thereby expanding the size of the market for Gaucher disease treatments.

Gaucher Disease Background
 
Gaucher disease, a hereditary, genetic disorder with severe and debilitating symptoms, is the most prevalent lysosomal storage disorder in humans. Lysosomal storage disorders are metabolic disorders in which a lysosomal enzyme, a protein that degrades cellular substrates in the lysosomes of cells, is mutated or deficient. Lysosomes are small membrane-bound cellular structures within cells that contain enzymes necessary for intracellular digestion. Gaucher disease is caused by mutations or deficiencies in the gene encoding GCD, a lysosomal enzyme that catalyzes the degradation of the fatty substrate, glucosylceramide (GlcCer). The normal degradation products of GlcCer are glucose and ceramide, which are easily excreted by the cells through normal biological processes. Patients with Gaucher disease lack or otherwise have dysfunctional GCD and, accordingly, are not able to break down GlcCer. The absence of an active GCD enzyme leads to the accumulation of GlcCer in lysosomes of certain white blood cells called macrophages. Macrophages affected by the disease become highly enlarged due to the accumulation of GlcCer and are referred to as “Gaucher cells.” Gaucher cells accumulate in the spleen, liver, lungs, bone marrow and brain. Signs and symptoms of Gaucher disease may include enlarged liver and spleen, abnormally low levels of red blood cells and platelets and skeletal complications. In some cases, the patient may suffer an impairment of the central nervous system.
 
Current Treatments for Gaucher Disease
 
The standard of care for Gaucher disease is enzyme replacement therapy using recombinant GCD to replace the mutated or deficient natural GCD enzyme. It is estimated that there are approximately 12,000 people suffering from Gaucher disease worldwide, but only approximately 6,000 patients are undergoing treatment. Enzyme replacement therapy is a medical treatment in which recombinant enzymes are injected into patients in whom the enzyme is lacking or dysfunctional. Cerezyme and VPRIV, enzyme replacement therapies commercialized by Genzyme and Shire, respectively, are the only recombinant GCDs currently available on the market for the treatment of Gaucher disease. As enzyme replacement therapy does not cure the genetic disorder, but rather provides an external source for transfusion of the missing or mutated enzyme, Gaucher patients generally receive the treatment over their entire lifetime. According to public reports by Sanofi, consolidated sales of Cerezyme during the year ended December 31, 2013 were €688 million (or approximately $950 million), a growth of approximately 14% compared to the same period in 2012. Shire reported annual worldwide sales of VPRIV of approximately $343 million in 2013, a growth of 12% compared to VPRIV’s sales in 2012.
 
Cerezyme is produced through a mammalian cell-based protein expression process in CHO cells and VPRIV is produced using a human cancer cell line. There are no known severe side effects to the use of Cerezyme or VPRIV, and Cerezyme’s approved use over the past decade suggests that it is an effective treatment of Gaucher disease. However, Cerezyme and VPRIV are both subject to the limitations of most mammalian cell-based therapeutic proteins, including lengthy and costly production processes and contamination risks.
 
Zavesca (miglustat), which is marketed by Actelion Ltd., or Actelion, is a small molecule drug for the treatment of Gaucher disease. Zavesca has been approved by the FDA for use in the United States as an oral treatment. However, it has many side effects and the FDA has approved it only for administration to those patients who cannot be treated through ERT, and, accordingly, have no other treatment alternative. As a result, Zavesca’s use has been limited with respect to treating Gaucher disease. However, Zavesca is also used to treat other rare disorders. Actelion has reported total sales of Zavesca of approximately CHF 96 million (approximately $109 million) in 2013, an increase of approximately 13% compared to sales in 2012.
 
Taliglucerase Alfa Development Program
 
We completed a phase I clinical trial in 2006 and, after discussions with the FDA, we proceeded directly with a pivotal phase III clinical trial of taliglucerase alfa without undergoing a phase II clinical trial. We reported positive top-line results of the phase III clinical trial in October 2009 and full study results in February 2010. This study was summarized in a publication in BLOOD, the Journal of the American Hematological Society (Zimran,  et .  al ., September 2011).
 
Phase III Clinical Trial and Related Studies
 
We initiated enrollment and treatment of naive patients in our phase III clinical trial in 2007, after having reached an agreement with the FDA regarding the design of the study through the FDA’s special protocol assessment (SPA) process. Consistent with the SPA, the phase III clinical trial was a multi-center, world-wide, randomized, double-blind, parallel group, dose-ranging study to assess the safety and efficacy of taliglucerase alfa in 31 treatment-naive patients suffering from Gaucher disease. In the trial, patients were selected randomly for one of two dosing arms (60 U/kg or 30 U/kg) and received intravenous infusions of taliglucerase alfa once every two weeks for a nine-month period. The primary endpoint of the study was a 20% mean reduction from baseline in spleen volume after nine months, as measured by MRI. Major secondary endpoints were an increase in hemoglobin, decrease in liver volume and increase in platelet count. Patients enrolled in the trial were treated in 11 selected leading medical centers throughout Europe, Israel, North America, South America and South Africa. Enrollment was completed in the fourth quarter of 2008 and the trial was successfully completed in September 2009.

During the third quarter of 2008, we initiated a double blind, follow-on extension study as part of our phase III clinical trial. Eligible patients who successfully completed nine months of treatment in our phase III clinical trial were offered the opportunity to participate in the extension study and to continue to receive taliglucerase alfa at the same dose they received in the phase III clinical trial for an additional 15 months in a blinded manner. Accordingly, the extension trial included two treatment groups; one treated with a 60 U/kg dose and the other with a 30 U/kg dose. The major endpoints of the study were spleen volume, liver volume, hemoglobin concentration, platelet count, and chitotriosidase activity. Twenty-six patients were originally enrolled in the extension trial which was performed in centers throughout Europe, Israel, North America, South America and South Africa. Three of the 26 patients enrolled in the extension trial discontinued treatment; one switched to our compassionate use program, one was unable to comply with study protocol and one had a skin reaction during month 15. We also initiated a home care treatment program for patients enrolled in the extension study.
 
In addition, in the fourth quarter of 2008, we announced the enrollment of the first patient in a worldwide, multi-center, open-label, switch-over trial to assess the safety and efficacy of taliglucerase alfa. The switch-over trial, which was not a prerequisite for approval, was originally designed to include 15 Gaucher patients that were currently undergoing ERT with imiglucerase (Cerezyme). Due to the shortage of Cerezyme in 2009, after fully enrolling 15 patients, we extended the trial to include additional patients. A total of 26 adult patients were enrolled in the switchover trial. Patients enrolled in the trial were switched from imiglucerase (doses ranging from approximately 10-60 U/kg every other week) to an equivalent dose using the same number of units of taliglucerase alfa over a nine-month period.
 
In 2010 we initiated a clinical trial of naïve pediatric patients which we completed in 2012. Eleven treatment-naive patients with symptoms and clinical manifestations of Gaucher disease between the ages of two and eighteen were enrolled in the trial. Patients were randomized to receive two different doses in a blinded manner; five patients were treated with a 60 U/kg dose and six patients were treated with a 30 U/kg dose. The primary endpoint of the study was change in hemoglobin concentration, and the secondary endpoints were change of spleen volume, liver volume, platelet count and chitotriosidase activity. Patients were enrolled in clinics in Israel, Paraguay, and South Africa.
 
Results of our Phase III Clinical Trial and Extension Trial
 
We reported positive top-line results of our phase III clinical trial of taliglucerase alfa in October 2009 and full study results in February 2010.  In the clinical trial, taliglucerase alfa significantly reduced mean spleen volume after nine months compared with baseline in both treatment groups, thereby meeting the trial’s primary endpoint of reduced mean spleen volume after nine months.  In February 2013, we announced interim data from 23 adult patients enrolled in our extension trial.  According to the interim data, after 36 months (nine months in the phase III clinical trial and 27 months in the extension trial), patients continued to demonstrate a significant improvement in all parameters with a similar safety profile as seen in the phase III clinical trial.
 
In the phase III clinical trial, the 60 U/kg group demonstrated a statistically significant mean reduction in spleen volume of 38.0% (p<0.0001) and the 30 U/kg group demonstrated a significant mean reduction in spleen volume of 26.9% (p<0.0001). In addition, the primary endpoint was achieved in both treatment groups after only six months of therapy. Patients treated with taliglucerase alfa in the extension trial continued to demonstrate a statistically significant reduction in mean spleen volume after 36 months, compared with baseline, in both treatment groups; reductions of 62.0% in the 60 U/kg group and of 47.0% in the 30 U/kg group.
 
Statistically significant improvements were also observed for the secondary endpoints of the phase III clinical trial, including increase in hemoglobin level, decrease in liver size and increase in platelet count, after nine months when compared to baseline for the 60 U/kg dose. These improvements continued in the extension trial. Patients in both dosage groups demonstrated mean increases in hemoglobin from baseline; mean increases from 11.4 g/DL to 13.6 g/DL (p<0.0001) (22.2%) in the 60 U/kg group and from 12.2 g/DL to 14.0 g/DL (p<0.0010) (14.8%). In the extension trial, at 36 months, clinically significant mean increases in hemoglobin concentration were also demonstrated by both groups; mean increases from baseline, from 11.0 g/DL to 14.0 g/DL (27.3%), in the 60 U/kg group and mean increases from baseline, from 12.4 g/DL to 14.3 g/DL (15.3%), in the 30 U/kg group. Patients with anemia demonstrated a mean increase from baseline in hemoglobin concentration, from 9.5 g/DL to 13.1 g/DL (37.9%); patients with normal hemoglobin show a mean increase of 10.3% in hemoglobin, from 13.6 g/DL at baseline to 15.0 g/DL after 36 months of treatment.
 
In the phase III clinical trial, patients in both dosage groups demonstrated mean decrease (reduction) in liver volume; reductions of 11.1% (p<0.0001) in the 60 U/kg group and of 10.48% (p<0.0041) in the 30 U/kg group. In the extension trial, at 36 months, both groups demonstrated clinically significant mean reductions in liver volume; reductions of 19.0% in the 60 U/kg group and of 21.0% in the 30 U/kg group; patients with Hepatomegaly demonstrated a reduction in liver volume of 30.0% in the 60 U/kg group and of 22.0% in the 30 U/kg group.

In the phase III clinical trial, patients in both dosage groups demonstrated mean increases in platelet count; an increase in platelet count of 41,494 ml or 72.1% (p=0.0031) in the 60 U/kg group, and a nominal increase of 11,427 ml or 13.7% (p=0.0460) in the 30 U/kg group. Accordingly, the lower dose group did not meet the secondary endpoint relating to platelet count. In the extension trial, at 36 months, both groups demonstrated clinically significant mean increases in platelet count; increases from 73,055 to 136,027 in the 60 U/kg group and from 64,900 to 94,683 in the 30 U/kg group.
 
Last, 30 patients in the phase III clinical trial had chitotriosidase measurements, a biomarker of Gaucher disease. In these patients, chitotriosidase decreased from baseline in both the 30U/kg and 60U/kg groups by 47.3% and 58.4%, respectively. In the extension trial, at 36 months, mean reductions in chitotriosidase activity were demonstrated by both groups; a reduction of 83.0% in the 60 U/kg group and of 73.5% in the 30 U/kg group.
 
The safety analysis for both treatment groups in the phase III clinical trial showed that taliglucerase alfa was well tolerated and no serious or severe adverse events were reported. The safety analysis in the extension trial for both treatment groups at 36 months also demonstrates that taliglucerase alfa was well tolerated, and no drug related serious adverse events were reported.
 
In the phase III clinical trial, no serious related adverse event was reported and most of the adverse events were considered unrelated to taliglucerase alfa. The most frequent mild to moderate adverse event was headache. Other mild to moderate adverse events included dizziness, muscle spasm, chest discomfort, nausea, skin irritation and arthalgia. Adverse events in the extension trial included headache, pruritus, hypersensitivity, abdominal pain, fixed drug eruption, arthalgia and infusion related reactions (dizziness, chills, nausea).
 
Results of Our Switchover Trial; Long Term Data
 
In November 2010, we announced positive preliminary data from the first 15 patients that completed our switchover trial of taliglucerase alfa, and in February 2012 we reported full results from 25 adult patients in the trial.  In February 2013, we announced interim results from an extension trial related to the switchover trial at 36 months.  The results of the first trial demonstrate that over a nine-month treatment period of the study, patients remained stable with regard to all of the efficacy endpoints (hemoglobin concentration, platelet count, spleen and liver volume) and chitotriosidase activity after switching to taliglucerase alfa from imiglucerase. The safety analysis presented for the switchover trial demonstrates that taliglucerase alfa was well tolerated, and no drug related serious adverse events were reported. Additionally, all drug-related adverse effects were mild or moderate and transient in nature.
 
Nineteen of the 25 patients in the switchover trial elected to continue to be treated in an extension trial for an additional 12 months. Five of the six patients that did not proceed to the extension trial continued to be treated with taliglucerase alfa through our compassionate use program; one patient was unable to comply with the extension study protocol and therefore was unable to participate. A 24-month interim analysis of the switchover trial demonstrates that patients remained stable with regard to all of the efficacy endpoints and chitotriosidase activity after switching to taliglucerase alfa from imiglucerase. The safety analysis presented for the extended switchover trial demonstrates that taliglucerase alfa was well tolerated, and no drug related serious adverse events were reported. Four of the nineteen patients enrolled in the extension trial discontinued treatment; one switched to our compassionate use program, one enrolled in another clinical trial, one was unable to comply with study protocol and one was not pleased with that individual’s personal results. In conclusion, the data demonstrates that taliglucerase alfa has a well-established safety profile and is an effective alternative treatment for adult Gaucher patients previously treated with imiglucerase.
 
Results of Our Pediatric Trial
 
In July 2012, we announced data from our clinical trial of taliglucerase alfa in pediatric Gaucher patients.  After 12 months of treatment with taliglucerase alfa, changes in hemoglobin concentration were demonstrated by both dosage groups, with increases of 15.8% in the 60 U/kg group and of 13.8% in the 30 U/kg group.  In addition, significant improvements were also seen in all secondary endpoints.  Spleen volumes decreased by 41.1% in patients receiving 60 U/kg, and by 28.6% in patients receiving 30 U/kg of taliglucerase alfa.  Similarly, liver volumes decreased by 14.0% in the 60 U/kg group and 6.3% in the 30 U/kg group.  Both treatment groups also demonstrated improvements in platelet counts with a 73.7% increase from baseline in the 60 U/kg group, and a 30.9% increase from baseline in the 30 U/kg group.  Lastly, the chitotriosidase activity decreased from baseline, with a 66.0% reduction in patients receiving 60 U/kg and a 58.0% reduction in patients receiving 30 U/kg.  The majority of the treatment-related adverse events were mild or moderate in intensity, and transient in nature.  One severe adverse event was assessed as treatment-related; gastroenteritis. The event was reported as serious due to the need for hospitalization for rehydration. This patient continues to receive taliglucerase alfa. Subsequently, Pfizer submitted to the FDA a supplemental request to the ELEYSO NDA covering the treatment of pediatric Gaucher patients.

Long-Term Bone Marrow Responses
 
As bone disease is one of the most debilitating features of Gaucher disease, quantification of bone marrow involvement is important for monitoring the response to treatment. Therefore, our phase III clinical trial and the extension trial included bone marrow fat fraction (Ff) measured by quantitative chemical shift imaging (QCSI) as an exploratory parameter to evaluate bone marrow response in eight treatment naïve Gaucher patients with intact spleens that participated in the trials. Ff results were compared to outcomes in 15 untreated Dutch Gaucher patients with a follow-up interval of one year. Five taliglucerase alfa treated patients had a Ff below the threshold that relates to complication risk (<0.23) at baseline (median (n=8) 0.19, range 0.11-0.35). Ff significantly increased compared to baseline (p=0.012) and compared to untreated patients (p=0.005), already after one year of follow-up with further improvement up to 36 months. In four patients with the lowest Ff, the higher dose resulted in increases above 0.23 within one year. All eight patients had sustained improvements in all other parameters. There was no influence of antibodies on response parameters. This data demonstrates that treatment with taliglucerase alfa results in significant increases in lumbar spine fat fractions, which indicates clearance of Gaucher cells from the bone marrow.
 
Our Pipeline Drug Candidates
 
PRX-102 for the Treatment of Fabry Disease
 
We are developing PRX-102, our proprietary plant cell expressed chemically modified version of the recombinant alpha-GAL-A protein, a therapeutic enzyme, for the treatment of Fabry disease, a rare genetic lysosomal storage disorder. We believe that PRX-102 has the potential to be an improved version of the currently marketed Fabry disease enzymes, Fabrazyme ®  and Replagal ® , with improved activity in the Fabry disease target organs and significantly longer half-life due to higher stability, which together can potentially lead to improved substrate clearance. We believe that the treatment of Fabry disease is a specialty clinical niche with the potential for high growth.
 
Fabry Disease Background
 
Fabry disease is characterized by subnormal or absent enzymatic activity of alpha-GAL-A, a lysosomal enzyme which primarily catalyses the hydrolysis of terminal alpha-galactosyl groups of glycolipids, mainly the glycosphingolipid globotriaosylceramide (Gb3). The accumulation of Gb3 in body tissues results in Fabry disease. The ultimate consequence of glycosphingolipid deposition in the vasculature and other tissues is end-organ failure, particularly of the kidney, but also of the heart and cerebrovascular system. In addition, involvement of the central, peripheral and autonomic nervous systems results in episodes of pain and impaired peripheral sensation. Fabry disease affects approximately 8,000 people globally. In PRX-102, the prh-alpha-GALA, naturally occurring as a homodimer, is PEGylated and cross-linked to support and reinforce the homodimeric structure, which is crucial for the enzymatic activity of this enzyme. PRX-102 has been shown to be taken up by Fabry patients’ cells where it localizes to the lysosome, in which Gb3 accumulates. PRX-102 is characterized by higher stability under physiologically relevant conditions, and extended circulation residence time as compared to current ERTs for Fabry disease.
 
Current Treatments for Fabry Disease
 
Currently there are two drugs available on the market to treat Fabry disease. Fabrazyme, marketed by Genzyme, is approved for the treatment of Fabry disease in the United States and the European Union. Sanofi reported €383 million (approximately $509 million) in worldwide sales of Fabrazyme in 2013, a growth of 39% compared to 2012. The other approved drug for the treatment of Fabry disease in the European Union is Replagal, which is marketed by Shire. Shire reported $467.9 million in sales of Replagal in 2013, a decline of 6% compared to 2012. According to public reports by Shire, during 2012 Shire withdrew its Biologics License Application (BLA) for Replagal with the FDA.
 
PRX-102 Development Program
 
PRX-102 has demonstrated a significantly longer circular half-life than that of Replagal, over 40 times greater. In preclinical tests, we compared enzymatic activity of both PRX-102 and Replagal in human plasma and found that Replagal had a 13 minute half-life compared to a half-life of 581 minutes for PRX-102. See Figure 1.

Figure 1. Enhanced Circulatory Half-Life

 
In addition to the significantly greater half-life, our animal studies of PRX-102 demonstrate that the enzyme exhibits higher activity levels in target organs over time in Fabry mice after a single injection. See Figures 2 and 3.

In December 2012, the first patient was treated with PRX-102 in our phase I/II clinical trial of Fabry patients. The phase I/II clinical trial is a worldwide, multi-center, open label, dose ranging study to evaluate the safety, tolerability, pharmacokinetics and exploratory efficacy parameters of PRX-102 in adult Fabry patients. The trial is designed to enroll 18 adult Fabry patients, each in one of three dosing groups. Each patient will receive intravenous infusions of PRX-102 every two weeks for 12 weeks. After the completion of the protocol, we intend to offer enrolled trial patients the option to continue to receive PRX-102 in an open-label extension study.
 
Based on the pre IND meeting we held with the FDA in 2010, our experience with taliglucerase alfa and the experience of other companies developing ERTs for Fabry disease, we have reason to believe that, if favorable data is accumulated in our phase I/II clinical trial, the FDA may allow us to proceed directly with a pivotal phase III clinical trial. However, there can be no assurance that we will successfully complete our phase I/II clinical trial and if we do, that the trial will result in favorable data. In addition, there can be no assurance that the FDA will allow us to proceed directly with a phase III clinical trial after completion of our phase I/II clinical trial.
 
In pre-clinical studies, PRX-102 demonstrated preliminary efficacy in a Fabry animal model. Chemical modifications made to PRX-102 improved the enzyme’s activity and stability resulting in prolonged activity profiles and enhanced bioavailability in animals. The modifications also have the potential to decrease the immunogenicity of the enzyme, which is a major drawback of currently approved therapies for Fabry disease.

PRX-112; Orally Administered GCD for the Treatment of Gaucher Disease
 
We are developing PRX-112, an orally-delivered glucocerebrosidase (GCD) enzyme for the potential enzyme replacement therapy treatment of Gaucher disease. This is representative of a potential method for delivering active recombinant proteins systemically through oral administration of plant cells expressing biotherapeutic proteins. Oral GCD is a plant cell-expressed form of GCD that is naturally encapsulated within carrot cells genetically engineered to express the GCD enzyme. Plant cells have the unique attribute of a cellulose cell wall which makes them resistant to enzyme degradation when passing through the digestive tract. The plant cell itself serves as a delivery vehicle, once released and absorbed, to transport the enzyme in active form to the bloodstream. If proven effective, our experimental oral GCD would be the first protein to be administered orally rather than through intravenous therapy.
 
We believe that oral delivery of GCD presents a number of advantages. First, oral GCD consists of the same transformed genetically modified carrot plant root cells expressing prGCD from which we derive the active drug substance taliglucerase alfa. Therefore, it has the advantage of leveraging the well-characterized mechanism of action of our intravenously-administered taliglucerase alfa product. In addition, daily dosing of GCD provides potentially better clinical benefit and improved PK profile than the current, once every two weeks IV bolus of enzyme. We expect that providing Gaucher patients with a constant and continuous supply of this housekeeping enzyme should demonstrate a greater physiological effect compared to bolus delivery of enzyme via IV therapy. We also expect that raising the non-sufficient endogenous enzyme levels in Gaucher patients to levels of active enzyme present in the circulation, should be sufficient to prevent accumulation of the substrate. For these reasons, we believe that oral delivery of GCD may dramatically change the treatment paradigm for Gaucher patients, compared to the intravenous delivery of taliglucerase alfa, and contribute to increased compliance and the facilitation of treatment management.
 
Our oral taliglucerase alfa product candidate is a recombinant form of the GCD enzyme, not a small molecule. This differentiates our oral product candidate from other small molecule, oral drugs. Small molecule based treatments for Gaucher disease, such as Zavesca and Eliglustat, have different and less specific mechanisms of action than those associated with ERT. We have filed patent applications with respect to this new protein delivery mechanism in countries with commercially significant markets. Currently, we are the exclusive owners of all rights to this technology.
 
We believe that our oral delivery mechanism could be applied to additional proteins and has the potential to change the method of protein administration in certain indications.
 
Oral GCD Development Program
 
We completed a phase I clinical trial of oral GCD in Israel for which we announced results in February 2014. It was an exploratory, open label study to evaluate the safety and pharmacokinetics of oral GCD in Gaucher patients. Patients receive re-suspended lyophilized carrot cells in a single oral administration during the first segment of the trial and three consecutive daily administrations during the second segment of the trial. The primary objective of the trial was to measure the safety of oral GCD in Gaucher patients. Additional objectives included an evaluation of oral GCD’s pharmacokinetic profile and exploratory endpoints. The results demonstrate that oral GCD was well tolerated across all three doses tested. No patient discontinued the study prematurely, there were no drug related serious adverse events (SAE) reported and no treatment-induced antibodies were detected in any of the patients participating in the trial. All adverse reactions were transient in nature, mild and moderate and the patients that experienced the adverse reactions recovered without further events. One patient experienced nausea related to treatment and two patients experienced mild dizziness and dizziness, which was possibly related to treatment.
 
Pharmacokinetic (PK) studies revealed that active GCD enzyme was detected in the patients’ blood circulation, measured in the well-established assay in leucocytes of Gaucher patients, following oral administration of oral GCD. C max analysis showed an average increase of over 100% in enzymatic activity from base line, with an increase ranging from approximately 50% to 350% among the different, individual patients in the study. In general, the PK profile of oral GCD has a pattern of continuous enzyme presence over approximately 30 hours from administration. Platelet levels in 3 out of 8 thrombocytopenic Gaucher patients tested showed meaningful, rapid and unexpected improvement in platelet count after short-term treatment with oral GCD. The data demonstrates platelet count increases ranging from 27% to 78% from base line. See Figure 4. Thus, with a daily oral administration of oral GCD, we expect to achieve a steady state level of active GCD enzyme in the blood circulation of patients similar to the physiological state in healthy individuals.

Platelet levels in 3 out of 8 thrombocytopenic Gaucher patients tested showed meaningful, rapid and unexpected improvement in platelet count after short-term treatment with Oral GCD. The data demonstrates platelet count increases ranging from 27% to 78% from base line.
 
Preclinical studies of oral GCD were performed on rodents and large animals. To test the enzymatic activity of oral GCD, we tested the enzyme by feeding rats and pigs lyophilized carrot cells expressing GCD. The results of the study show that, based on preliminary PK data, we can detect the enzyme in the plasma of the animals, and that active enzyme is detected in the target organs, the spleen and liver, demonstrating the ability of a plant cell’s cellulose wall to protect the enzyme against degradation in the animal’s digestive tract. In addition, data from large and small animals demonstrate active absorbance of the protein in the plasma.

Other Drug Candidates in Our Pipeline
 
We are developing other innovative recombinant therapeutic proteins to be expressed by our ProCellEx protein expression system, with an emphasis on treatments for which there are large, established pharmaceutical markets and where our proprietary protein expression system enables us to develop and commercialize recombinant proteins that are patent-protected and therapeutically equivalent or superior to the existing treatments. We select additional therapeutic candidates for development by testing candidates in-house and through collaborations with academic partners.

PRX-106; Oral antiTNF
 
Our oral antiTNF product candidate is a recombinant antiTNF (Tumor, Necrosis Factor) protein that we are expressing through ProCellEx. We are developing oral antiTNF an orally-administered treatment for immune mediated disorders using plant cells as a natural capsule for the expressed protein. In preclinical studies, oral PRX-106 alleviated immune-mediated hepatitis and reduced interferon gamma levels in a concanavalin A (ConA) inflammatory mouse model. Additionally, oral administration of PRX-106 alleviated immune mediated colitis in a well-established mouse model, promoting serum levels of anti-inflammatory IL-10 and regulatory T-cells. Oral antiTNF has an amino acid sequence that is similar to Enbrel which is one of the major treatments for patients of inflammatory diseases. Amgen Inc. reported total sales of Enbrel of approximately $4.6 billion, primarily in the United States, for 2013 and Pfizer has reported total sales of Enbrel outside of the United States and Canada of approximately $3.8 billion for 2013.
 
pr-antiTNF is a plant cell-expressed recombinant fusion protein made from the binding domain of the human TNF receptor (TNFR), fused to the Fc component of a human antibody domain. It has an identical amino acid sequence to Enbrel and our in vitro and preclinical animal studies have demonstrated that pr-antiTNF exhibits similar activity to Enbrel. Our earlier preclinical studies first focused on the intravenous administration of antiTNF.  In vitro  studies demonstrated that purified PRX-106 administered intravenously binds to TNF alpha, thereby inhibiting it from binding to cellular TNF receptors, and preventing its downstream effects, such as TNF-induced apoptosis, in a dose-dependent manner. In a proof-of-concept  in vivo  study using a well-established preclinical arthritis model, antiTNF (IV), when injected in mice, significantly improved clinical arthritis parameters, including joint inflammation, swelling and tissue degradation.
 
We are now conducting additional preclinical studies on oral antiTNF for several attractive indications, and we expect to initiate a phase I clinical trial of oral anti TNF for the oral treatment of autoimmune diseases in 2014.
 
PRX-110; DNase I
 
PRX-110 is our plant cell recombinant form of human deoxyribonuclease I (DNase I) that we are developing for the potential treatment of Cystic Fibrosis, to be administered by inhalation. DNase I cleaves extracellular DNA and thins the thick mucus that accumulates in the lungs of Cystic Fibrosis patients.
 
In vitro studies with PRX-110 demonstrated improved enzyme kinetics, less sensitivity to inhibition by actin and improved ex vivo efficacy when compared to Pulmozyme®, the only approved form of recombinant DNase I. Preclinical studies of PRX-110 administered by inhalation showed substantial enzymatic activity in lungs. We held a pre-IND meeting with the FDA in 2012 and plan to file an IND with the FDA in 2014.
 
Commercialization Agreement for taliglucerase alfa
 
On November 30, 2009, Protalix Ltd. and Pfizer entered into the Pfizer Agreement pursuant to which Pfizer was granted an exclusive, worldwide license to develop and commercialize taliglucerase alfa. Under the terms and conditions of the Pfizer Agreement, Protalix Ltd. retained the right to commercialize taliglucerase alfa in Israel and Brazil. In connection with the execution of the Pfizer Agreement, Pfizer made an upfront payment to Protalix Ltd. of $60.0 million in connection with the execution of the agreement and subsequently paid Protalix Ltd. an additional $5.0 million upon our filing of a proposed pediatric investigation plan to the Pediatric Committee of the EMA. Protalix Ltd. also received a milestone payment of $25.0 million in connection with the May 2012 approval of taliglucerase alfa by the FDA. In addition to the milestone payments, Protalix Ltd. is eligible to payments equal to 40% of the net profits earned by Pfizer on sales of taliglucerase alfa (or share 40% of the net loss). In calculating the net profits, there are certain agreed upon limits on the amounts that may be deducted from gross sales for certain expenses and costs of goods sold. Protalix Ltd. retained the manufacturing rights to taliglucerase alfa, and Pfizer and Protalix Ltd. agreed to a specific allocation of the responsibilities for the continued development efforts for taliglucerase alfa prior to its approval. Protalix Ltd. will manufacture all of the taliglucerase alfa needed for all purposes under the agreement and Pfizer will purchase the taliglucerase alfa from Protalix Ltd., subject to certain terms and conditions. The Pfizer Agreement also provides for reimbursement by Pfizer of certain costs to be incurred by Protalix Ltd.
 
In December 2012, we entered into a clinical development agreement with Pfizer pursuant to which Protalix will continue to manage, administer and sponsor current, ongoing clinical trials relating to taliglucerase alfa. Protalix is currently sponsoring adult and pediatric extension studies of taliglucerase alfa. New clinical trials for taliglucerase alfa will be conducted and sponsored by Pfizer. Protalix Ltd. received a milestone payment of $8.3 million upon the achievement of certain near-term clinical development milestones set forth in the agreement.
 
17	

 	
 
In connection with the upfront and milestone payments made under the Pfizer Agreement, Protalix Ltd. has paid a sublicense fee equal to $2.3 million to the academic institution from who it licensed certain technology relating to taliglucerase alfa. Any future regulatory approval milestone payment due under the Pfizer Agreement, if at all, will be subject to a 2.5% royalty, and all other revenues generated under the agreement will be subject to a 0.35% royalty payable to the same institution until 2016, when a patent related to taliglucerase alfa licensed to us will expire. We are also required to pay a royalty ranging between 3.0% and 6.0% of the revenues of taliglucerase alfa Pfizer records under the Pfizer Agreement to the Office of the Chief Scientist of Israel’s Ministry of Industry, Trade and Labor, or the OCS.
 
We will be subject to a withholding tax on the U.S. revenue source portion of the payments made to us for our share of Pfizer’s in net profits under the Pfizer Agreement. Currently, the withholding tax rate is 15%.
 
Technology Transfer Agreement with Fiocruz
 
We entered into the Brazil Agreement with Fiocruz in June 2013, which agreement became effective in January 2014. The technology transfer is designed to be completed in four stages and is intended to transfer to Fiocruz the capacity and skills required for the Brazilian government to construct its own manufacturing facility, at its sole expense, and to produce a sustainable, high-quality, and cost-effective supply of taliglucerase alfa. The initial term of the technology transfer is seven years. Under the agreement, Fiocruz has committed to purchase at least approximately $40 million worth of taliglucerase alfa during the first two years of the term. In subsequent years, Fiocruz is required to purchase at least approximately $40 million worth of taliglucerase alfa per year. Additionally, we are not required to complete the final stage of the technology transfer until Fiocruz purchases at least approximately $280 million worth of taliglucerase alfa.
 
The Brazil Agreement may be extended for an additional five-year term, as needed, to complete the technology transfer. All of the terms of the arrangement, including the minimum annual purchases, will apply during the additional term. Upon completion of the technology transfer, and subject to Fiocruz receiving approval from ANVISA to manufacture taliglucerase alfa in its facility in Brazil, the agreement will enter into the final term and will remain in effect until our last patent in Brazil expires. During such period, Fiocruz will be the sole provider of this important treatment option for Gaucher patients in Brazil and shall pay us a single-digit royalty on net sales.
 
To facilitate the arrangement with Fiocruz, we and Pfizer agreed to an amendment of our exclusive license and supply agreement, which amendment provides for the transfer of the commercialization and other rights to taliglucerase alfa in Brazil back to us. As consideration for the transfer of the commercialization and supply rights, we agreed to pay Pfizer a maximum amount of approximately $12.5 million from its net profits (as defined in the license and supply agreement) per year. Pfizer has also agreed to perform certain transitional services in Brazil on our behalf in connection with the supply of taliglucerase alfa to Fiocruz.
 
We will pay a fee equal to 5% of the net proceeds generated in Brazil to our agent for services provided in assisting us complete the Brazil Agreement pursuant to an agency agreement between us and the agent. The agency agreement will remain in effect with respect to the Brazil Agreement until the termination thereof.
 
Other Collaborations
 
Teva Pharmaceutical Industries
 
In September 2006, we entered into a Collaboration and Licensing Agreement with Teva for the development and manufacture of two proteins to be identified by Teva and us using our ProCellEx protein expression system. The agreement also identifies additional matters for collaboration between Teva and us. Subsequently, two proteins were identified to be researched and developed under the agreement but in 2009, both of the projects were terminated for commercial reasons. Pursuant to the agreement, we have agreed to collaborate on certain additional matters regarding proteins, including the research and development of proteins utilizing our ProCellEx protein expression system. See “Risk Factors-Our strategy, in certain cases, is to enter into collaboration agreements with third parties to leverage our ProCellEx system to develop product candidates. If we fail to enter into these agreements or if we or the third parties do not perform under such agreements or terminate or elect to discontinue the collaboration, it could have a material adverse effect on our revenues.”
 
Intellectual Property
 
We maintain a proactive intellectual property strategy which includes patent filings in multiple jurisdictions, including the United States and other commercially significant markets. As of December 31, 2013, we hold, or have license rights to 49 patents and 89 pending patent applications with respect to various compositions, methods of production and methods of use relating to our ProCellEx protein expression system and our proprietary product pipeline. As of December 31, 2013, we hold, with a third party, one joint patent and one joint patent application, and licensed rights to five patents and six patent applications.
 
18	

 	
 
Our competitive position and future success depend in part on our ability, and that of our licensees, to obtain and leverage the intellectual property covering our product candidates, know-how, methods, processes and other technologies, to protect our trade secrets, to prevent others from using our intellectual property and to operate without infringing the intellectual property of third parties. We seek to protect our competitive position by filing United States, European Union, Israeli and other foreign patent applications covering our technology, including both new technology and improvements to existing technology. Our patent strategy includes obtaining patents, where possible, on methods of production, compositions of matter and methods of use. We also rely on know-how, continuing technological innovation, licensing and partnership opportunities to develop and maintain our competitive position.

We are aware of U.S. patents, and corresponding international counterparts of such patents, owned by third parties that contain claims covering methods of producing GCD. We do not believe that, if any claim of infringement were to be asserted against us based upon such patents, taliglucerase alfa would be found to infringe any valid claim under such patents. However, there can be no assurance that a court would find in our favor or that, if we choose or are required to seek a license to any one or more of such patents, a license would be available to us on acceptable terms or at all.
 
In April 2005, Protalix Ltd. entered into a license agreement with Icon Genetics AG, or Icon, pursuant to which we received an exclusive worldwide license to develop, test, use and commercialize Icon’s technology to express certain proteins in our ProCellEx protein expression system. Under the terms of the agreement, we are also entitled to a non-exclusive worldwide license to make and have made other proteins expressed by using Icon’s technology in our technology. As consideration for the license, we are obligated to make royalty payments equal to varying low, single-digit percentages of net sales of products by us, our affiliates, or any sublicensees under the agreement. In addition, we are obligated to make milestone payments equal to $350,000, in the aggregate for each product developed under the license, upon the achievement of certain milestones.
 
Our license agreement with Icon remains in effect until the earlier of the expiration of the last patent under the agreement or, if all of the patents under the agreement expire, 20 years after the first commercial sale of any product under the agreement. Icon may terminate the agreement upon written notice to us that we are in material breach of our obligations under the agreement and we are unable to remedy such material breach within 30 days after we receive such notice. Further, Icon may terminate the agreement in connection with certain events relating to a wind up or bankruptcy, if we make a general assignment for the benefit of our creditors, or if we cease to conduct operations for a certain period. Icon may also terminate the exclusivity granted to us by written notice if we fail to reach certain milestones within a designated period of time. Notwithstanding the termination date of the agreement, our obligation to pay royalties to Icon under the agreement may expire prior to the termination of the agreement, subject to certain conditions.
 
In January 2005, Protalix Ltd. entered into a license agreement with Virginia Tech University, pursuant to which we received a non-exclusive worldwide license to make, have made, use, sell, offer for sale and import certain of Virginia Tech’s patents. As consideration for the license, we made a one-time license fee payment to Virginia Tech, and we are obligated to make royalty payments equal to varying low, single-digit percentages of net sales of licensed products by Protalix Ltd., its subsidiaries and/or their affiliates. Upon commercialization of a licensed product, the royalty payment is subject to a low, annual minimum amount. In addition, we were obligated to make milestone payments equal to $150,000, in the aggregate, upon the achievement of certain milestones, which milestone payments have been satisfied. We have the right to grant sublicenses under the agreement.

Our license agreement with Virginia Tech remains in effect until the earlier of the expiration of the last patent under the agreement or 10 years after the first commercial sale of any licensed product. Virginia Tech may terminate the agreement upon written notice to us that we are in material breach of our obligations under the agreement if we are unable to remedy such material breach within a fixed number of days after we receive such notice, which number may be doubled if we are making good faith efforts to achieve a cure and the extension will not increase the damages suffered by Virginia Tech. We have the right to terminate the agreement at any time upon prior written notice delivered an agreed-upon number of days prior to the date of termination.
 
Manufacturing
 
We are obligated to manufacture all of the taliglucerase alfa drug product needed under the Pfizer Agreement, subject to certain terms and conditions. Our drug product candidates, including taliglucerase alfa, must be manufactured in a sterile environment and in compliance with cGMPs set by the FDA and other relevant foreign regulatory authorities. We use our current facility, which has approximately 20,000 sq/ft of clean rooms built according to industry standards, to develop, process and manufacture taliglucerase alfa and other recombinant proteins. We intend to use our current manufacturing space to produce all of the taliglucerase alfa we need in the near future, included the taliglucerase alfa to be purchased by Pfizer. In addition, we intend to use our manufacturing space to produce all of the drug substance needed in connection with the clinical trials of PRX-102 and of our oral treatment of Gaucher disease, and potentially for our other product candidates. Current capacity of our facility can serve all of our current and expected commercial and clinical needs.
 
Our manufacturing facilities in Carmiel, Israel, have undergone successful audits by the Israeli MOH, the FDA, ANVISA, and the European Union under the European Union’s centralized marketing authorization procedure, the Australian TGA and Health Canada.
 
We have engaged a contract manufacturer in Europe to act as an additional source of fill and finish activities for taliglucerase alfa. According to our agreement with Pfizer, Pfizer will be responsible for the fill and finish activities for taliglucerase alfa. We have engaged other contract manufacturers to perform fill/finish activities for PRX-102 and for our oral treatment of Gaucher disease.
 
Our current facility in Israel has been granted “Approved Enterprise” status, and we have elected to participate in the alternative benefits program. Our facility is located in a Zone A location, and, therefore, our income from the Approved Enterprise will be tax exempt in Israel for a 10-year period commencing with the year in which we first generate taxable income from the relevant Approved Enterprise and after we use our NOLs. We expect to be entitled to similar tax benefits for a number of years thereafter. To remain eligible for these tax benefits, we must continue to meet certain conditions, and if we increase our activities outside of Israel, for example, by future acquisitions, such increased activities generally may not be eligible for inclusion in Israeli tax benefit programs. In addition, our technology is subject to certain restrictions with respect to the transfer of technology and manufacturing rights. “See Risk Factors-The manufacture of our products is an exacting and complex process, and if we or one of our materials suppliers encounter problems manufacturing our products, it will have a material adverse effect on our business and results of operations.”
 
Raw Materials and Suppliers
 
We believe that the raw materials that we require throughout the manufacturing process of our current and potential drug product candidates are widely available from numerous suppliers and are generally considered to be generic industrial biological supplies. We rely on a single approved supplier for certain materials relating to the current expression of our proprietary biotherapeutic proteins through ProCellEx. We have identified additional suppliers for most of the materials required for the production of our product candidates.
 
Development and regulatory approval of our pharmaceutical products are dependent upon our ability to procure active ingredients and certain packaging materials from sources approved by the FDA and other regulatory authorities. Since the FDA and other regulatory approval processes require manufacturers to specify their proposed suppliers of active ingredients and certain packaging materials in their applications, FDA approval of a supplemental application to use a new supplier in connection with any drug candidate or approved product, if any, would be required if active ingredients or such packaging materials were no longer available from the specified supplier, which could result in manufacturing delays. From time to time, we intend to continue to identify alternative FDA-approved suppliers to ensure the continued supply of necessary raw materials.

Competition
 
The biotechnology and pharmaceutical industries are characterized by rapidly evolving technology and significant competition. Competition from numerous existing companies and others entering the fields in which we operate is intense and expected to increase. Most of these companies have substantially greater research and development, manufacturing, marketing, financial, technological personnel and managerial resources than we do. In addition, many specialized biotechnology companies have formed collaborations with large, established companies to support research, development and commercialization of products that may be competitive with our current and future product candidates and technologies. Acquisitions of competing companies by large pharmaceutical or biotechnology companies could further enhance such competitors’ financial, marketing and other resources. Academic institutions, governmental agencies and other public and private research organizations are also conducting research activities and seeking patent protection and may commercialize competitive products or technologies on their own or through collaborations with pharmaceutical and biotechnology companies.
 
We specifically face competition from companies with approved treatments of Gaucher disease. In addition to ELELYSO, there are two other ERTs for the treatment of Gaucher disease; Cerezyme which is marketed by Genzyme (acquired by Sanofi) and VPRIV, which is marketed by Shire. To a much lesser extent, we also compete with Actelion. In addition, Genzyme is developing Eliglustat which is in the late stages of clinical development and was the subject of a phase III clinical trial that was completed in 2013. Eliglustat is a small molecule, oral drug which is being developed for the treatment of Gaucher disease.
 
There are two approved ERTs for the treatment of Fabry disease; Fabrazyme which is marketed by Genzyme and Replagal, which is marketed by Shire. Fabrazyme is available in the United States and the European Union. Replagal is available in the European Union. In 2012, Shire withdrew its BLA for Replagal in the United States. In addition, we are aware of other clinical stage, early clinical stage and experimental drugs which are being developed for the treatment of Fabry disease by Amicus Therapeutics and other companies.
 
We also face competition from companies that are developing other platforms for the expression of recombinant therapeutic pharmaceuticals. We are aware of companies that are developing alternative technologies to develop and produce therapeutic proteins in anticipation of the expiration of certain patent claims covering marketed proteins. Competitors developing alternative expression technologies include Crucell N.V. (which was acquired by Johnson & Johnson during 2010), Shire and GlycoFi, Inc. (which was acquired by Merck & Co. Inc.). Other companies are developing alternate plant-based technologies, include, among others, iBio, Inc., Medicago, and Greenovation Biotech GmbH, none of which are cell-based. Rather, such companies base their product development on transgenic plants or whole plants.
 
Several biogeneric companies are pursuing the opportunity to develop and commercialize follow-on versions of other currently marketed biologic products, including growth factors, hormones, enzymes, cytokines and monoclonal antibodies, which are areas that interest us. These companies include, among others, Novartis AG/Sandoz Pharmaceuticals, BioGeneriX AG, Stada Arzneimittel AG, BioPartners GmbH and Teva.

Government Regulation
 
The testing, manufacture, distribution, advertising and marketing of drug products are subject to extensive regulation by federal, state and local governmental authorities in the United States, including the FDA, and by similar authorities in other countries. Any product that we develop must receive all relevant regulatory approvals or clearances, as the case may be, before it may be marketed in a particular country.
 
The regulatory process, which includes overseeing preclinical studies and clinical trials of each pharmaceutical compound to establish its safety and efficacy and confirmation by the FDA that good laboratory, clinical and manufacturing practices were maintained during testing and manufacturing, can take many years, requires the expenditure of substantial resources and gives larger companies with greater financial resources a competitive advantage over us. Delays or terminations of clinical trials that we undertake would likely impair our development of product candidates. Delays or terminations could result from a number of factors, including stringent enrollment criteria, slow rate of enrollment, size of patient population, having to compete with other clinical trials for eligible patients, geographical considerations and others.
 
The FDA review process can be lengthy and unpredictable, and we may encounter delays or rejections of our applications when submitted. Generally, in order to gain FDA approval, we must first conduct preclinical studies in a laboratory and in animal models to obtain preliminary information on a compound and to identify any potential safety problems. The results of these studies are submitted as part of an IND application that the FDA must review before human clinical trials of an investigational drug can commence. Clinical trials may be terminated by the clinical trial site, sponsor or the FDA if toxicities appear that are either worse than expected or unexpected.
 
Clinical trials are normally performed in three sequential phases and generally take two to five years, or longer, to complete. Phase I consists of testing the drug product in a small number of humans, normally healthy volunteers, to determine preliminary safety and tolerable dose range. Phase II usually involves studies in a limited patient population to evaluate the effectiveness of the drug product in humans having the disease or medical condition for which the product is indicated, determine dosage tolerance and optimal dosage and identify possible common adverse effects and safety risks. Phase III consists of additional controlled testing at multiple clinical sites to establish clinical safety and effectiveness in an expanded patient population of geographically dispersed test sites to evaluate the overall benefit-risk relationship for administering the product and to provide an adequate basis for product labeling. Phase IV clinical trials may be conducted after approval to gain additional experience from the treatment of patients in the intended therapeutic indication.
 
23	

 	
 
After completion of clinical trials of a new drug product, FDA and foreign regulatory authority marketing approval must be obtained. Assuming that the clinical data support the product’s safety and effectiveness for its intended use, an NDA is submitted to the FDA for its review. Generally, it takes one to three years to obtain approval. If questions arise during the FDA review process, approval may take a significantly longer period of time. The testing and approval processes require substantial time and effort and approval on a timely basis, if at all, or the approval that we receive may be for a narrower indication than we had originally sought, potentially undermining the commercial viability of the product. Even if regulatory approvals are obtained, approved products are subject to continual review and holders of an approved product are required, for example, to report certain adverse reactions and production problems, if any, to the FDA, and to comply with certain requirements concerning advertising and promotional labeling for the product. Also, quality control and manufacturing procedures relating to a product must continue to conform to cGMP after approval, and the FDA periodically inspects manufacturing facilities to assess compliance with cGMP. Accordingly, manufacturers must continue to expend time, money and effort in the area of production and quality control to comply with cGMP and other aspects of regulatory compliance. The later discovery of previously unknown problems or failure to comply with the applicable regulatory requirements with respect to any product may result in restrictions on the marketing of the product or withdrawal of the product from the market as well as possible civil or criminal sanctions. See also “-International Regulation.”
 
Under the Orphan Drug Act of 1983, the FDA may grant orphan drug designation to drugs and biological products intended to treat a rare disease or condition, which is generally a disease or condition that affects fewer than 200,000 individuals in the United States. In September 2009, we received orphan drug designation for taliglucerase alfa for the treatment of Gaucher disease. The FDA grants orphan drug designation to drugs that may provide a significant therapeutic advantage over existing treatments and target conditions affecting 200,000 or fewer U.S. patients per year. Orphan drug designation does not convey any advantage in or shorten the duration of the regulatory review and approval process. Among the other benefits of orphan drug designation are possible funding and tax savings to support clinical trials and for other financial incentives and a waiver of the marketing application user fee and most likely priority review. If a significant therapeutic advantage over existing treatments is shown in the marketing application, FDA may grant orphan drug approval and provide a seven-year period of marketing exclusivity.
 
The FDA has a fast track program that is intended to expedite or facilitate the process for reviewing new drugs and biological products that meet certain criteria. Specifically, new drugs and biological products are eligible for fast track designation if they are intended to treat a serious or life-threatening condition and demonstrate the potential to address unmet medical needs for the condition. Fast track designation applies to the combination of the product and the specific indication for which it is being studied. For a fast track product, the FDA may consider for review on a rolling basis sections of the NDA before the complete application is submitted, if the sponsor provides a schedule for the submission of the sections of the NDA, the FDA agrees to accept sections of the NDA as they become available and determines that the schedule is acceptable, and the sponsor pays any required user fees upon submission of the first section of the NDA. We used the rolling submission option for our taliglucerase alfa NDA, which we completed in April 2010.
 
The United States federal government regulates healthcare through various agencies, including but not limited to the following: (i) the FDA, which administers the Federal Food, Drug, and Cosmetic Act (FDCA), as well as other relevant laws; (ii) the Center for Medicare & Medicaid Services (CMS), which administers the Medicare and Medicaid programs; (iii) the Office of Inspector General (OIG) which enforces various laws aimed at curtailing fraudulent or abusive practices, including by way of example, the Anti-Kickback Law, the Anti-Physician Referral Law, commonly referred to as Stark, the Anti-Inducement Law, the Civil Money Penalty Law and the laws that authorize the OIG to exclude healthcare providers and others from participating in federal healthcare programs; and (iv) the Office of Civil Rights, which administers the privacy aspects of the Health Insurance Portability and Accountability Act of 1996 (HIPAA). All of the aforementioned are agencies within the Department of Health and Human Services (HHS). Healthcare is also provided or regulated, as the case may be, by the Department of Defense through its TriCare program, the Department of Veterans Affairs, especially through the Veterans Health Care Act of 1992, the Public Health Service within HHS under Public Health Service Act § 340B (42 U.S.C. § 256b), the Department of Justice through the Federal False Claims Act and various criminal statutes, and state governments under the Medicaid and other state sponsored or funded programs and their internal laws regulating all healthcare activities. Many states also have anti-kickback and anti-physician referral laws that are similar to the federal laws, but may be applicable in situations where federal laws do not apply.
 
Medicare is the federal healthcare program for those who are (i) over 65 years of age, (ii) disabled, (iii) suffering from end-stage renal disease or (iv) suffering from Lou Gehrig’s disease. Medicare consists of part A, which covers inpatient costs, part B, which covers services by physicians and laboratories, durable medical equipment and certain drugs, primarily those administered by physicians, and part D, which provides drug coverage for most prescription drugs other than those covered under part B. Medicare also offers a managed care option under part C. Medicare is administered by CMS. In contrast, Medicaid is a state-federal healthcare program for the poor and is administered by the states pursuant to an agreement with the Secretary of Health and Human Services. Most state Medicaid programs cover most outpatient prescription drugs.

In March 2010, the Patient Protection and Affordable Care Act, as amended by the Health Care and Education Affordability Reconciliation Act, or collectively, PPACA, became law in the United States. PPACA substantially changes the way healthcare is financed by both governmental and private insurers and significantly affects the pharmaceutical industry. Key provisions of PPACA specific to the pharmaceutical industry, among others, include the following:
 
 	·	An annual, nondeductible fee on any entity that manufactures or imports certain branded prescription drugs and biologic agents into the United States, apportioned among these entities according to their market share in certain federal government healthcare programs (excluding sales of any drug or biologic product marketed for an orphan indication), beginning in 2011;	
 
 	·	An increase in the rebates a manufacturer must pay under the Medicaid Drug Rebate Program, retroactive to January 1, 2010, to 23.1% and 13% of the average manufacturer price for branded and generic drugs, respectively;	
 
 	·	A new Medicare Part D coverage gap discount program, in which manufacturers must agree to offer 50% point-of sale discounts off negotiated prices of applicable brand drugs to eligible beneficiaries during their coverage gap period, as a condition for the manufacturer’s outpatient drugs to be covered under Medicare Part D, beginning in 2011;	
 
 	·	Extension of manufacturers’ Medicaid rebate liability to covered drugs dispensed to individuals who are enrolled in Medicaid managed care organizations, effective March 23, 2010;	
 
 	·	Expansion of eligibility criteria for Medicaid programs by, among other things, allowing states to offer Medicaid coverage to additional individuals beginning in April 2010 and by adding new mandatory eligibility categories for certain individuals with income at or below 133% of the Federal Poverty Level beginning in 2014, thereby potentially increasing both the volume of sales and manufacturers’ Medicaid rebate liability;	
 
 	·	Expansion of the entities eligible for discounts under the Public Health Service pharmaceutical pricing program, effective January 2010;	
 
 	·	New requirements to report certain financial arrangements with physicians and others, including reporting any “transfer of value” made or distributed to prescribers and other healthcare providers and reporting any investment interests held by physicians and their immediate family members during each calendar year beginning in 2012, with reporting starting in 2013;	
 
 	·	A new requirement to annually report drug samples that manufacturers and distributors provide to physicians, effective April 1, 2012;	
 
 	·	A licensure framework for follow-on biologic products; and	
 
 	·	A new Patient-Centered Outcomes Research Institute to oversee, identify priorities in, and conduct comparative clinical effectiveness research, along with funding for such research.	
 
International Regulation
 
We are subject to regulations and product registration requirements in many foreign countries in which we may sell our products, including in the areas of product standards, packaging requirements, labeling requirements, import and export restrictions and tariff regulations, duties and tax requirements. The time required to obtain clearance required by foreign countries may be longer or shorter than that required for FDA clearance, and requirements for licensing a product in a foreign country may differ significantly from FDA requirements.
 
Pharmaceutical products may not be imported into, or manufactured or marketed in, the State of Israel absent drug registration. The three basic criteria for the registration of pharmaceuticals in Israel is quality, safety and efficacy of the pharmaceutical product and the Israeli MOH requires pharmaceutical companies to conform to international developments and standards. Regulatory requirements are constantly changing in accordance with scientific advances as well as social and ethical values.
 
25	

 	
 
The relevant legislation of the European Union requires that medicinal products, including generic versions of previously approved products, and new strengths, dosage forms and formulations, of previously approved products, shall have a marketing authorization before they are placed on the market in the European Union. Authorizations are granted after the assessment of quality, safety and efficacy by the respective health authorities. In order to obtain an authorization, an application must be made to the competent authority of the member state concerned or in a centralized procedure to the EMA. Besides various formal requirements, the application must contain the results of pharmaceutical (physico-chemical, biological or microbiological) tests, of preclinical (toxicological and pharmacological) tests as well as of clinical trials. All of these tests must have been conducted in accordance with relevant EU regulations and must allow the reviewer to evaluate the quality, safety and efficacy of the medicinal product. Orphan drug designation in the European Union is granted to medicinal products intended for the diagnosis, prevention and treatment of life-threatening diseases and very serious conditions that affect not more than five in 10,000 people in the European Union. Orphan drug designation is generally given to medicinal products that treat conditions for which no current therapy exists or are expected to bring a significant benefit to patients over existing therapies.
 
Israeli Government Programs
 
The following is a summary of the current principal Israeli tax laws applicable to us and Protalix Ltd., and of the Israeli Government programs from which Protalix Ltd. benefits. Some parts of this discussion are based on new tax legislation that has not been subject to judicial or administrative interpretation. Therefore, the views expressed in the discussion may not be accepted by the tax authorities in question. The discussion should not be construed as legal or professional tax advice and does not cover all possible tax considerations.
 
General Corporate Tax Structure in Israel
 
The income of Protalix Ltd., other than income from “Approved Enterprises,” is taxed in Israel at the regular rate.
 
On July 14, 2009 the Economic Efficiency Law (Legislation Amendments for the Implementation of the Economic Plan for the years 2009 and 2010), 2009, or the 2009 Amendment, was passed in the Knesset; this law determined, inter alia, a further gradual reduction of the corporate tax rate as from 2011, as follows: 2011 - 24%, 2012 - 23%, 2013 - 22%, 2014 - 21%, 2015 - 20%, 2016 and thereafter - 18%.
 
On December 6, 2011, the “Tax Burden Distribution Law” was officially published, discontinuing a previously approved gradual decrease in corporate tax provided in the 2009 Amendment, and setting the corporate tax rate in Israel for 2012 and thereafter to 25%.
 
On August 5, 2013, the Law for Change of National Priorities (Legislative Amendments for Achieving the Budgetary Goals for 2013-2014), 2013 was published in Reshumot (the Israeli government official gazette), enacting, among other things, an increase in the corporate tax rate beginning in 2014 and thereafter to 26.5% (instead of 25%).
 
Capital gains on the sale of assets are subject to capital gain tax according to the corporate tax rate in effect for the year the assets are sold.
 
In addition to the corporate taxes in Israel, we are subject to a withholding tax on the U.S. revenue source portion of the payments made to us for our share of Pfizer’s net profits under the Pfizer Agreement. The withholding tax rate is 15%. See “Business-Commercialization Agreement.”
 
Law for the Encouragement of Capital Investments, 1959.
 
The Law for the Encouragement of Capital Investments, 1959, or the Investment Law, provides certain incentives for capital investments in a production facility (or other eligible assets). Generally, an investment program that is implemented in accordance with the provisions of the Investment Law, referred to as an “Approved Enterprise,” is entitled to benefits. These benefits may include cash grants from the Israeli government and tax benefits, based upon, among other things, the location of the facility in which the investment is made and specific elections made by the grantee.
 
Protalix Ltd. will continue to enjoy the tax benefits under the pre-revision provisions of the Investment Law. If any new benefits are granted to Protalix Ltd. in the future, Protalix Ltd. will be subject to the provisions of the amended Investment Law with respect to these new benefits. Therefore, the following discussion is a summary of the Investment Law prior to its amendment as well as the relevant changes contained in the new legislation.
 
Under the Investment Law prior to its amendment, a company that wished to receive benefits had to receive approval from the “Investment Center” of the Israeli Ministry of Industry, Trade and Labor, or the Investment Center. Each certificate of approval for an Approved Enterprise relates to a specific investment program in the Approved Enterprise, delineated both by the financial scope of the investment and by the physical characteristics of the facility or the asset, e.g., the equipment to be purchased and utilized pursuant to the program.
 
26	

 	
 
An Approved Enterprise may elect to forego any entitlement to the grants otherwise available under the Investment Law and, instead, participate in an alternative benefits program under which the undistributed income from the Approved Enterprise is fully exempt from corporate tax for a defined period of time. Under the alternative package of benefits, a company’s undistributed income derived from an Approved Enterprise will be exempt from corporate tax for a period of between two and 10 years from the first year of taxable income, depending upon the geographic location within Israel of the Approved Enterprise. Upon expiration of the exemption period, the Approved Enterprise is eligible for the reduced tax rates otherwise applicable under the Investment Law for any remainder of the otherwise applicable benefits period (up to an aggregate benefits period of either seven or 10 years, depending on the location of the company or its definition as a foreign investors’ company). If a company has more than one Approved Enterprise program or if only a portion of its capital investments are approved, its effective tax rate is the result of a weighted combination of the applicable rates. The tax benefits from any certificate of approval relate only to taxable profits attributable to the specific Approved Enterprise. Income from activity that is derived from different Approved Enterprises does not enjoy these tax benefits.
 
A company that has an Approved Enterprise program is eligible for further tax benefits if it qualifies as a foreign investors’ company. A foreign investors’ company eligible for benefits is essentially a company in which more than 25% of the share capital (in terms of shares, rights to profit, voting and appointment of directors) is owned (measured by both share capital and combined share and loan capital) by non-Israeli residents. A company that qualifies as a foreign investors’ company and has an Approved Enterprise program is eligible for tax benefits for a 10-year benefit period and may enjoy a reduced corporate tax rate of 10% to 25%, depending on the amount of the company’s shares held by non-Israeli shareholders.
 
If a company that has an Approved Enterprise program is a wholly owned subsidiary of another company, the percentage of foreign investments is determined based on the percentage of foreign investment in the parent company. The tax rates and related levels of foreign investments are set forth in the following table:
 
Percent of Foreign
Ownership	 	 	Rate of Reduced
Tax	
 	 	 	 	
0-49%	 	 	 	25%	
49-74%	 	 	 	20%	
74-90%	 	 	 	15%	
90-100%	 	 	 	10%	
 
Our original facility in Israel has been granted “Approved Enterprise” status, and it has elected to participate in the alternative benefits program. Under the terms of its Approved Enterprise program, the facility is located in a top priority location, or “Zone A,” and, therefore, the income from that Approved Enterprise will be tax exempt in Israel for a period of 10 years, commencing with the year in which taxable income is first generated from the relevant Approved Enterprise. The current benefits program may not continue to be available and Protalix Ltd. may not continue to qualify for its benefits.
 
A company that has elected to participate in the alternative benefits program and that subsequently pays a dividend out of the income derived from the Approved Enterprise during the tax exemption period will be subject to corporate tax in respect of the amount distributed at the rate that would have been applicable had the company not elected the alternative benefits program (generally 10% to 25%, depending on the extent to which non-Israeli shareholders hold such company’s shares). If the dividend is distributed within 12 years after the commencement of the benefits period (or, in the case of a foreign investor’s company, without time limitation), the dividend recipient is taxed at the reduced withholding tax rate of 15% applicable to dividends from approved enterprises, or at the lower rate under an applicable tax treaty. After this period, the withholding tax rate is 25%, or at the lower rate under an applicable tax treaty. In the case of a company with a foreign investment level (as defined by the Investment Law) of 25% or more, the 12-year limitation on reduced withholding tax on dividends does not apply. The company must withhold this tax at its source, regardless of whether the dividend is converted into foreign currency.
 
The Investment Law also provides that an Approved Enterprise is entitled to accelerated depreciation on its property and equipment that are included in an approved investment program. This benefit is an incentive granted by the Israeli government regardless of whether the alternative benefits program is elected.
 
The benefits available to an Approved Enterprise are conditioned upon terms stipulated in the Investment Law and regulations and the criteria set forth in the applicable certificate of approval. If Protalix Ltd. does not fulfill these conditions in whole or in part, the benefits can be canceled and Protalix Ltd. may be required to refund the received benefits, linked to the Israeli consumer price index with the addition of interest or alternatively with an additional penalty payment. We believe that Protalix Ltd. currently operates in compliance with all applicable conditions and criteria, but there can be no assurance that Protalix Ltd. will continue to do so. Furthermore, there can be no assurance that any Approved Enterprise status granted to Protalix Ltd.’s facilities will entitle Protalix Ltd. to the same benefits to which it is currently entitled.
 
27	

 	
 
Under the Investment Law, the approval of the Investment Center is required only for Approved Enterprises that receive cash grants. Approved Enterprises that do not receive benefits in the form of governmental cash grants, but only tax benefits, are no longer required to obtain this approval. Instead, these Approved Enterprises are required to make certain investments as specified in the Investment Law.
 
The amended Investment Law specifies certain conditions for an Approved Enterprise to be entitled to benefits. These conditions include:
 
 	·	the Approved Enterprise’s revenues from any single country or a separate customs territory may not exceed 75% of the Approved Enterprise’s total revenues; or	
 
 	·	at least 25% of the Approved Enterprise’s revenues during the benefits period must be derived from sales into a single country or a separate customs territory with a population of at least 14 million.	
 
There can be no assurance that Protalix Ltd. will comply with the above conditions in the future or that Protalix Ltd. will be entitled to any additional benefits under the Investment Law. In addition, it is possible that Protalix Ltd. may not be able to operate in a manner that maximizes utilization of the potential benefits available under the Investment Law.
 
From time to time, the Israeli Government has considered reducing the benefits available to companies under the Investment Law. The termination or substantial reduction of any of the benefits available under the Investment Law could materially impact the cost of our future investments.
 
Encouragement of Industrial Research and Development Law, 1984
 
To date, Protalix Ltd. has received grants from the OCS for the financing of a portion of its research and development expenditures in Israel. As of December 31, 2013, the OCS approved grants in respect of Protalix Ltd.’s continuing operations totaling approximately $31.8 million, measured from inception. Protalix Ltd. is required to repay up to 100% of grants actually received (plus interest at the LIBOR rate applied to the grants received on or after January 1, 1999) to the OCS through payments of royalties at a rate of 3% to 6% of the revenues generated from an OCS-funded project, depending on the period in which revenues were generated. As of December 31, 2013, Protalix Ltd. either paid or accrued royalties payable of $4.7 million and Protalix Ltd.’s contingent liability to the OCS with respect to grants received was approximately $27.6 million.
 
Under the Israeli Law for the Encouragement of Industrial Research and Development, 1984, and related regulations, or the Research Law, recipients of grants from the OCS are prohibited from manufacturing products developed using these grants outside of the State of Israel without special approvals, although the Research Law does enable companies to seek prior approval for conducting manufacturing activities outside of Israel without being subject to increased royalties. If Protalix Ltd. receives approval to manufacture the products developed with government grants outside of Israel, it will be required to pay an increased total amount of royalties (possibly up to 300% of the grant amounts plus interest), depending on the manufacturing volume that is performed outside of Israel, as well as at a possibly increased royalty rate.
 
Additionally, under the Research Law, Protalix Ltd. is prohibited from transferring the OCS-financed technologies and related intellectual property rights outside of the State of Israel, except under limited circumstances and only with the approval of the OCS’ Research Committee. Protalix Ltd. may not receive the required approvals for any proposed transfer and, if received, Protalix Ltd. may be required to pay the OCS a portion of the consideration that it receives upon any sale of such technology by a non-Israeli entity. The scope of the support received, the royalties that Protalix Ltd. has already paid to the OCS, the amount of time that has elapsed between the date on which the know-how was transferred and the date on which the OCS grants were received and the sale price and the form of transaction will be taken into account in order to calculate the amount of the payment to the OCS. Approval of the transfer of technology to residents of the State of Israel is required, and may be granted in specific circumstances only if the recipient abides by the provisions of applicable laws, including the restrictions on the transfer of know-how and the obligation to pay royalties. No assurance can be made that approval to any such transfer, if requested, will be granted.
 
Under the Research Law, the Research Committee to allow the transfer outside of Israel of know-how derived from an approved program and the related manufacturing rights. In general, the Research Committee may approve transfer of know-how in limited circumstances as follows:
 
28	

 	
 
 	·	in the event of a sale of know-how itself to a non-affiliated third party, provided that upon such sale the owner of the know-how pays to the OCS an amount, in cash, as set forth in the Research Law. In addition, the amendment provides that if the purchaser of the know-how gives the selling Israeli company the right to exploit the know-how by way of an exclusive, irrevocable and unlimited license, the research committee may approve such transfer in special cases without requiring a cash payment.	
 
 	·	in the event of a sale of a company which is the owner of know-how, pursuant to which the company ceases to be an Israeli company, provided that upon such sale, the owner of the know-how makes a cash payment to the OCS as set forth in the Research Law.	
 
 	·	in the event of an exchange of know-how such that in exchange for the transfer of know-how outside of Israel, the recipient of the know-how transfers other know-how to the company in Israel in a manner in which the OCS is convinced that the Israeli economy realizes a greater, overall benefit from the exchange of know-how.	
 
The Research Committee may, in special cases, approve the transfer of manufacture or of manufacturing rights of a product developed within the framework of the approved program or which results therefrom, outside of Israel.
 
The State of Israel does not own intellectual property rights in technology developed with OCS funding and there is no restriction on the export of products manufactured using technology developed with OCS funding. The technology is, however, subject to transfer of technology and manufacturing rights restrictions as described above. For a description of such restrictions, please see “Risk Factors-Risks Relating to Our Operations in Israel.” OCS approval is not required for the export of any products resulting from the research or development or for the licensing of any technology in the ordinary course of business.
 
Law for the Encouragement of Industry (Taxes), 1969
 
We believe that Protalix Ltd. currently qualifies as an “Industrial Company” within the meaning of the Law for the Encouragement of Industry (Taxes), 1969, or the Industry Encouragement Law. The Industry Encouragement Law defines “Industrial Company” as a company resident in Israel and incorporated in Israel, that derives 90% or more of its income in any tax year (other than specified kinds of passive income such as capital gains, interest and dividends) from an “Industrial Enterprise” operating in Israel (including Judea & Samara territories and the Gaza strip), that it owns. An “Industrial Enterprise” is defined as an enterprise whose major activity in a given tax year is industrial production.
 
The following corporate tax benefits, among others, are available to Industrial Companies:
 
 	·	amortization of the cost of purchased know-how and patents over an eight-year period for tax purposes;	
 	·	accelerated depreciation rates on equipment and buildings;	
 	·	under specified conditions, an election to file consolidated tax returns with other related Israeli Industrial Companies; and	
 	·	expenses related to a public offering are deductible in equal amounts over three years.	
 
Eligibility for the benefits under the Industry Encouragement Law is not subject to receipt of prior approval from any governmental authority. It is possible that Protalix Ltd. may fail to qualify or may not continue to qualify as an “Industrial Company” or that the benefits described above will not be available in the future.
 
Tax Benefits for Research and Development
 
Under specified conditions, Israeli tax laws allow a tax deduction by a company for research and development expenditures, including capital expenditures, for the year in which such expenditures are incurred. These expenditures must relate to scientific research and development projects and must be approved by the OCS. Furthermore, the research and development projects must be for the promotion of the company and carried out by or on behalf of the company seeking such tax deduction. However, the amount of such deductible expenditures is reduced by the sum of any funds received through government grants for the finance of such scientific research and development projects. Expenditures not so approved are deductible over a three-year period.

Employees
 
As of December 31, 2013, we had 260 employees, of whom 40 have a Ph.D. or an M.D.in their respective scientific fields. We believe that our relations with these employees are good. We believe that our success will greatly depend on our ability to identify, attract and retain capable employees. The Israeli Ministry of Labor and Welfare is authorized to make certain industry-wide collective bargaining agreements, or Expansion Orders, that apply to types of industries or employees including ours. These agreements affect matters such as cost of living adjustments to salaries, length of working hours and week, recuperation, travel expenses, and pension rights. Otherwise, our employees are not represented by a labor union or represented under a collective bargaining agreement. See “Risk Factors-We depend upon key employees and consultants in a competitive market for skilled personnel. If we are unable to attract and retain key personnel, it could adversely affect our ability to develop and market our products.”

Item 1A.	Risk Factors
 
You should carefully consider the risks described below together with the other information included in this Annual Report on Form 10-K. Our business, financial condition or results of operations could be adversely affected by any of these risks. If any of these risks occur, the value of our common stock could decline.
 
Risks Related to Our Financial Condition and Capital Requirements
 
We currently have no significant product revenues and may need to raise additional capital to operate our business, which may not be available on favorable terms, or at all, and which will have a dilutive effect on our shareholders.
 
To date, we have not generated significant revenues from product sales and only minimal revenues from research and development services and other fees, other than the milestone payments we have received in connection with our license and supply agreement with Pfizer. For the years ended December 31, 2013, 2012 and 2011, we had net losses of $27.8 million, $11.6 million and $36.5 million, respectively, primarily as a result of expenses incurred through a combination of research and development activities and expenses supporting those activities, which includes share-based compensation expense. Drug development and commercialization is very capital intensive. Our lead product was first approved for marketing by the FDA in May 2012, by the Israeli MOH in September 2012 and, subsequently, in certain other countries. We fund all of our operations and capital expenditures from the revenues we generate from sales of taliglucerase alfa supplemented with our cash on hand, other licensing fees and grants and the net proceeds of any equity or debt offerings. Based on our current plans and capital resources, we believe that our cash and cash equivalents will be sufficient to enable us to meet our planned operating needs for the foreseeable future. However, changes may occur that could consume our existing capital at a faster rate than projected, including, among others, the cost and timing of regulatory approvals, changes in the progress of our research and development efforts and the costs of protecting our intellectual property rights.
 
We may seek additional financing to implement and fund product development, preclinical studies and clinical trials for the drugs in our pipeline, as well as additional drug candidates and other research and development projects. If we are unable to secure additional financing in the future on acceptable terms, or at all, we may be unable to commence or complete planned preclinical and clinical trials or obtain approval of our drug candidates from the FDA and other regulatory authorities. In addition, we may be forced to reduce or discontinue product development or product licensing, reduce or forego sales and marketing efforts and other commercialization activities or forego attractive business opportunities in order to improve our liquidity and to enable us to continue operations which would have a material adverse effect on our business and results of operations. Any additional source of financing will likely involve the issuance of our equity securities, which will have a dilutive effect on our shareholders.
 
Risks Related to the Commercialization of taliglucerase alfa
 
We cannot predict the share in net income we will receive from Pfizer’s sales of taliglucerase alfa.
 
Taliglucerase alfa has been approved for marketing in the United States, Israel, Brazil, Mexico, Chile and Uruguay. Otherwise, we have no other products approved for marketing. As we have invested a significant portion of our efforts and financial resources in the development of taliglucerase alfa, our ability to generate product revenue depends heavily on the successful commercialization of taliglucerase alfa. Under the Pfizer Agreement, Pfizer holds an exclusive worldwide license to develop and commercialize taliglucerase alfa, except in Israel and Brazil. Sales of taliglucerase alfa worldwide (except Israel and Brazil) are dependent upon Pfizer’s sales and marketing efforts, which we do not control and may not be able to effectively influence, and on the actions and decisions of foreign regulatory authorities. Upon the approval of taliglucerase alfa in additional markets, if at all, Pfizer may experience delays in, or be unable to achieve, the commercial introduction of taliglucerase alfa in those markets, which would have a material adverse effect on our business, results of operations and financial condition.
 
Our future revenues under our collaboration with Pfizer from Pfizer’s sales of taliglucerase alfa will depend on a number of factors, including:
 
 	·	the number of Gaucher patients who will be treated with taliglucerase alfa;	
 	·	the willingness of Gaucher patients to switch from other ERTs to taliglucerase alfa;	
 	·	competition from Cerezyme and VPRIV, and other current or future approved treatments of Gaucher disease;	
 	·	Pfizer’s efforts under the Pfizer Agreement and the effectiveness of Pfizer’s commercial strategy and its execution of that strategy, including its pricing strategy and the effectiveness of its efforts to obtain adequate third-party reimbursements;	
 
31	

 	
 	·	obtaining marketing approvals from additional regulatory authorities;	
 	·	a continued acceptable safety and efficacy profile of our product candidates following approval;	
 	·	the successful audit of our facilities by additional regulatory authorities;	
 	·	maintaining the cGMP compliance of our manufacturing facility or establishing manufacturing arrangements with third parties; and	

 	·	the capacity of physicians and health care providers to provide treatment to Gaucher patients.	
 
We cannot accurately predict the amount of revenues we will generate under our collaboration with Pfizer in future periods, if any. Any failure to commercialize taliglucerase alfa or the experience of significant delays in doing so will have a material adverse effect on our business, results of operations and financial condition.
 
The market share and/or other indicators of market acceptance of taliglucerase alfa may not meet the expectations of investors or public market analysts, which would have a material adverse effect on our business, results of operations and financial condition and the market price of our common stock would likely decline.
 
Fiocruz may not comply with the terms and conditions of the Supply and Technology Transfer Agreement.
 
UPLYSO was first approved for marketing in Brazil in March 2013. Under our Supply and Technology Transfer Agreement, with Fiocruz, we are not required to complete the final stage of the technology transfer for the production of UPLYSON until Fiocruz purchases at least approximately $280 million worth of UPLYSO. However, we do not control and may not be able to effectively influence Fiocruz’s ability to distribute UPLYSO in Brazil. Any failure by Fiocruz to comply with the purchase requirements of the Supply and Technology Transfer Agreement, or any other material breach by Fiocruz of the agreement, may have a material adverse effect on our business, results of operations and financial condition.
 
We cannot accurately predict the amount of revenues we will generate under our Supply and Technology Transfer with Fiocruz in future periods, if any. Any failure by Fiocruz to distribute UPLYSO in Brazil, or the experience of significant delays in doing so, will have a material adverse effect on our business, results of operations and financial condition.
 
If safety issues regarding taliglucerase alfa that were not known at the time of approval are discovered, or if we or Pfizer fail to comply with continuing U.S. and applicable foreign regulations, commercialization efforts for taliglucerase alfa could be adversely affected and taliglucerase alfa could lose its approval or its sales could be suspended.
 
Drug products remain subject to continuing regulatory oversight after they are approved for marketing, including the review of additional safety information. Drugs are more widely used by patients once approved for sale and, therefore, side-effects and other problems may be observed after approval that were not seen or anticipated, or were not as prevalent or severe, during clinical trials or nonclinical studies. The subsequent discovery of previously unknown problems with a product could negatively affect commercial sales of the product, result in restrictions on the product or lead to the withdrawal of the product from the market. The reporting of adverse safety events involving taliglucerase alfa or public speculation about such events could cause our stock price to decline or experience periods of volatility and may have a material adverse effect on our business, results of operations and financial condition.
 
If we or Pfizer fail to comply with applicable continuing regulatory requirements, we or Pfizer may be subject to fines and/or criminal prosecutions, and taliglucerase may become subject to suspension or withdrawal of regulatory approval, product recalls and seizures and operating restrictions. In addition, the manufacturers we and Pfizer engage to produce taliglucerase alfa and the manufacturing facilities in which taliglucerase alfa is made are subject to periodic review and inspection by the FDA and foreign regulatory authorities. If problems are identified during the review or inspection of these manufacturers or manufacturing facilities, it could result in our inability to use the facility to make our product or a determination that inventories are not safe for commercial sale, which may have a material adverse effect on our business, results of operations and financial condition.
 
If physicians, patients, third party payors and others in the medical community do not accept and use taliglucerase alfa, or any of our other product candidates, if approved, our ability to generate revenue from product sales will be materially impaired.
 
Physicians and patients, and other healthcare providers, may not accept and use taliglucerase alfa or any of our other product candidates, if approved for marketing. Future acceptance and use of taliglucerase alfa or any of our other product candidates, if approved, will depend upon a number of factors including:
 
32	

 	
 
 	·	perceptions by physicians, patients, third party payors and others in the medical community about the safety and effectiveness of taliglucerase alfa or our other drug candidates;	
 	·	the willingness of the target patient population to try new therapies and of physicians to prescribe these therapies;	
 	·	the prevalence and severity of any side effects, including any limitations or warnings contained in our products’ approved labeling;	
 	·	pharmacological benefits of taliglucerase alfa or our other drug candidates relative to competing products and products under development;	
 	·	the efficacy and potential advantages relative to competing products and products under development;	
 	·	relative convenience and ease of administration;	
 	·	effectiveness of education, marketing and distribution efforts by us and our licensees and distributors, if any;	
 	·	publicity concerning taliglucerase alfa or our other drug candidates or competing products and treatments;	
 	·	coverage and reimbursement of our products by third party payors; and	
 	·	the price for our products and competing products.	
 
Because we expect sales of taliglucerase alfa to generate substantially all of our product revenues for the foreseeable future, any lack of market acceptance of taliglucerase alfa would have a material adverse effect on our business, results of operations and financial condition.
 
If the market opportunities for taliglucerase alfa or our other product candidates are smaller than we believe they are, our revenues may be adversely affected and our business may suffer.
 
To date, our development efforts have focused mainly on relatively rare disorders with small patient populations, in particular Gaucher disease and Fabry disease. Currently, most reported estimates of the prevalence of these diseases are based on studies of small subsets of the population of specific geographic areas, which are then extrapolated to estimate the prevalence of the diseases in the broader world population. As new studies are performed, the estimated prevalence of these diseases may change. There can be no assurance that the prevalence of Gaucher disease or Fabry disease in the study populations, particularly in these newer studies, accurately reflect the prevalence of these diseases in the broader world population. If the market opportunities for our current product candidates are smaller than we believe they are, our revenues may be adversely affected and our business may suffer.
 
Coverage and reimbursement may not be available for taliglucerase alfa or any of our other product candidates, if approved, in all territories which could diminish our sales or affect our ability to sell taliglucerase alfa or any other products profitably.
 
Market acceptance and sales of taliglucerase alfa or any of our other product candidates, if approved, will depend on worldwide coverage and reimbursement policies. Government authorities and third-party payors, such as private health insurers and health maintenance organizations, decide which drugs they will pay for and establish reimbursement levels. Although, to date taliglucerase alfa is covered and reimbursed in all the approved territories, coverage might not be available for taliglucerase alfa or any of our other product candidates, if approved, in all territories. Obtaining reimbursement approval for an approved product from governments and other third party payors is a time consuming and costly process that requires our collaborators or us, as the case may be, to provide supporting scientific, clinical and cost-effectiveness data for the use of our products, if and when approved, to every payor. We may not be able to provide data sufficient to gain acceptance with respect to coverage and reimbursement or we might need to conduct post-marketing studies in order to demonstrate the cost-effectiveness of approved products, if any, to such payors’ satisfaction. Such studies might require our collaborators or us to commit a significant amount of management time and financial and other resources. Even if a payor determines that taliglucerase alfa, or any other approved product, if any, is eligible for reimbursement, the payor may impose coverage limitations that preclude payment for some uses that are approved by the FDA or other regulatory authorities. In addition, full reimbursement may not be available for high priced products. Moreover, eligibility for coverage does not imply that any approved product will be reimbursed in all cases or at a rate that allows us to make a profit or even cover our costs. Also, limited reimbursement amounts may reduce the demand for, or the price of, our product candidates. Except with respect to taliglucerase alfa, we have not commenced efforts to have our product candidates covered and reimbursed by government or third-party payors. If coverage and reimbursement are not available or are available only to limited levels, the sales of our products, if approved may be diminished or we may not be able to sell such products profitably.

We and our collaborating partners may be subject, directly or indirectly, to federal and state healthcare fraud and abuse and false claims laws and regulations. If we or our collaborating partners are unable to comply, or have not fully complied, with such laws, we could face substantial penalties.
 
All marketing activities associated with taliglucerase alfa in the United States, as well as marketing activities in the United States related to any other products for which we obtain regulatory approval, if any, will be, directly or indirectly through our customers, subject to numerous federal and state laws governing the marketing and promotion of pharmaceutical products in the United States, including, without limitation, the federal Anti-Kickback Statute, the federal False Claims Act and HIPAA. These laws may adversely impact, among other things, our proposed sales, marketing and education programs.
 
The federal Anti-Kickback Statute prohibits persons from knowingly and willfully soliciting, receiving, offering or paying remuneration, directly or indirectly, to induce either the referral of an individual, or the furnishing, recommending, or arranging for a good or service, for which payment may be made under a federal healthcare program, such as the Medicare and Medicaid programs. The term “remuneration” has been broadly interpreted to include anything of value, including for example, gifts, discounts, the furnishing of supplies or equipment, credit arrangements, payments of cash, waivers of co-payments and deductibles, ownership interests and providing anything at less than its fair market value. The reach of the Anti-Kickback Statute was also broadened by the Patient Protection and Affordable Care Act, as amended by the Health Care and Education Affordability Reconciliation Act, or the PPACA, which, among other things, amends the intent requirement of the federal Anti-Kickback Statute and the applicable criminal healthcare fraud statutes contained within 42 U.S.C. § 1320a-7b, effective March 23, 2010. Pursuant to the statutory amendment, a person or entity no longer needs to have actual knowledge of this statute or specific intent to violate it in order to have committed a violation. In addition, PPACA provides that the government may assert that a claim including items or services resulting from a violation of the federal Anti-Kickback Statute constitutes a false or fraudulent claim for purposes of the civil False Claims Act (discussed below) or the civil monetary penalties statute, which imposes penalties against any person who is determined to have presented or caused to be presented a claim to a federal health program that the person knows or should know is for an item or service that was not provided as claimed or is false or fraudulent. The federal Anti-Kickback Statute is broad, and despite a series of narrow safe harbors, prohibits many arrangements and practices that are lawful in businesses outside of the healthcare industry. Penalties for violations of the federal Anti-Kickback Statute include criminal penalties and civil sanctions such as fines, imprisonment and possible exclusion from Medicare, Medicaid and other state or federal healthcare programs. Many states have also adopted laws similar to the federal Anti-Kickback Statute, some of which apply to the referral of patients for healthcare items or services reimbursed by any source, not only the Medicare and Medicaid programs, and do not contain identical safe harbors.
 
The federal False Claims Act imposes liability on any person who, among other things, knowingly presents, or causes to be presented, a false or fraudulent claim for payment by a federal healthcare program. The “qui tam” provisions of the False Claims Act allow a private individual to bring civil actions on behalf of the federal government alleging that the defendant has submitted a false claim to the federal government, and to share in any monetary recovery. In addition, various states have enacted false claims laws analogous to the False Claims Act. Many of these state laws apply where a claim is submitted to any third-party payer and not merely a federal healthcare program. When an entity is determined to have violated the False Claims Act, it may be required to pay up to three times the actual damages sustained by the government, plus civil penalties of $5,500 to $11,000 for each separate false claim.
 
The Health Insurance Portability and Accountability Act of 1996, or HIPAA, created several new federal crimes, including health care fraud, and false statements relating to health care matters. The health care fraud statute prohibits knowingly and willfully executing a scheme to defraud any health care benefit program, including private third-party payers. The false statements statute prohibits knowingly and willfully falsifying, concealing or covering up a material fact or making any materially false, fictitious or fraudulent statement in connection with the delivery of or payment for health care benefits, items or services.
 
We are unable to predict whether we could be subject to actions under any of these or other fraud and abuse laws, or the impact of such actions. Moreover, to the extent that taliglucerase alfa, or any of our products, if approved for marketing, will be sold in a foreign country, we and our collaborators, including Pfizer, may be subject to similar foreign laws and regulations. If we or any of our collaborators are found to be in violation of any of the laws described above and other applicable state and federal fraud and abuse laws, we may be subject to penalties, including civil and criminal penalties, damages, fines, exclusion from government healthcare reimbursement programs and the curtailment or restructuring or our operations, any of which could have a material adverse effect on our business, results of operations and financial condition.

Risks Related to Our Business
 
We have a limited operating history which may limit the ability of investors to make an informed investment decision.
 
Taliglucerase alfa is our only product with commercial approvals. The successful commercialization of our drug candidates will require us to perform a variety of functions, including:
 
 	·	continuing to perform preclinical development and clinical trials;	
 	·	participating in regulatory approval processes;	
 	·	formulating and manufacturing products; and	
 	·	conducting sales and marketing activities.	
 
Our operations have been limited to organizing and staffing our company, acquiring, developing and securing our proprietary technology and undertaking, through third parties, preclinical trials and clinical trials of our principal drug candidates. To date, we have commenced a phase III clinical trial in connection with only one drug candidate, taliglucerase alfa, which trial was completed in August 2009. These operations provide a limited basis for investors to assess our ability to commercialize our drug candidates and whether to invest in our company.
 
Our strategy, in certain cases, is to enter into collaboration agreements with third parties to leverage our ProCellEx system to develop product candidates. If we fail to enter into these agreements or if we or the third parties do not perform under such agreements or terminate or elect to discontinue the collaboration, it could have a material adverse effect on our revenues.
 
Our strategy, in certain cases, is to enter into arrangements with pharmaceutical companies to leverage our ProCellEx system to develop additional product candidates. Under these arrangements, we may grant to our partners rights to license and commercialize pharmaceutical products developed under the applicable agreements. Our partners may control key decisions relating to the development of the products and we may depend on our partners’ expertise and dedication of sufficient resources to develop and commercialize our product candidates. The rights of our partners limit our flexibility in considering alternatives for the commercialization of our product candidates. If we or any of our current or future partners breach or terminate the agreements that make up such arrangements, our partners otherwise fail to conduct their obligations under such arrangements in a timely manner, there is a dispute about their obligations or if either party terminates the applicable agreement or elects not to continue the arrangement, we may not enjoy the benefits of the agreements or receive a sufficient amount of royalty or milestone payments from them, if any, which may have a material adverse effect on our business, results of operations and financial condition.
 
We have limited experience in selling, marketing or distributing products and limited internal capability to do so.
 
We currently have very limited sales, marketing or distribution capabilities and no experience in building a sales force and distribution capabilities. Pfizer holds an exclusive, worldwide right to develop and commercialize taliglucerase alfa worldwide, except in Israel and Brazil. To be able to commercialize taliglucerase alfa effectively in Israel and Brazil, and to commercialize any of our other product candidates, we must either significantly increase our internal sales, marketing and distribution capabilities, which will be expensive and time consuming, or make arrangements with third parties to perform these services. If we decide to market any of our other products directly, if any, we must commit significant financial and managerial resources to develop a marketing and sales force with technical expertise and with supporting distribution capabilities. Factors that may inhibit our efforts to commercialize our products directly and without strategic partners include:
 
 	·	the inability to recruit and retain adequate numbers of effective sales and marketing personnel;	
 	·	the inability of sales personnel to obtain access to an adequate numbers of physicians or to pursuance them to prescribe our products;	
 	·	the lack of complementary products to be offered by sales personnel, which may put us at a competitive disadvantage relative to companies with more extensive product lines; and	
 	·	unforeseen costs and expenses associated with creating and sustaining an independent sales and marketing organization.	
 
We may not be successful in recruiting or retaining the sales and marketing personnel necessary to sell any of our products upon approval, if at all, which would have a material adverse effect on our business, results of operations and financial condition.
 
35	

 	
 
We may enter into distribution arrangements and marketing alliances for certain products and any failure to successfully identify and implement these arrangements on favorable terms, if at all, may impair our ability to commercialize our product candidates.
 
While we do sell directly taliglucerase alfa in Israel and Brazil and we intend to build a sales force to market other product candidates worldwide if approved, we do not anticipate having the resources in the foreseeable future to develop global sales and marketing capabilities for all of the products we develop. We may pursue arrangements regarding the sales and marketing and distribution of one or more of our product candidates, such as our current license and supply agreement with Pfizer for taliglucerase alfa, and our future revenues may depend, in part, on our ability to enter into and maintain arrangements with other companies having sales, marketing and distribution capabilities and the ability of such companies to successfully market and sell any such products. Any failure to enter into such arrangements and marketing alliances on favorable terms, if at all, could delay or impair our ability to commercialize our product candidates and could increase our costs of commercialization. Any use of distribution arrangements and marketing alliances to commercialize our product candidates will subject us to a number of risks, including the following:
 
 	·	we may be required to relinquish important rights to our products or product candidates;	
 	·	we may not be able to control the amount and timing of resources that our distributors or collaborators may devote to the commercialization of our product candidates;	
 	·	our distributors or collaborators may experience financial difficulties;	
 	·	our distributors or collaborators may not devote sufficient time to the marketing and sales of our products; and	
 	·	business combinations or significant changes in a collaborator’s business strategy may adversely affect a collaborator’s willingness or ability to complete its obligations under any arrangement.	
 
We may need to enter into additional co-promotion arrangements with third parties where our own sales force is neither well situated nor large enough to achieve maximum penetration in the market. We may not be successful in entering into any co-promotion arrangements, and the terms of any co-promotion arrangements we enter into may not be favorable to us.
 
Our ProCellEx protein expression system is based on our proprietary plant cell-based expression technology which has a limited history and any material problems with the system, which may be unforeseen, may have a material adverse effect on our business, results of operations and financial condition.
 
Our ProCellEx protein expression system is based on our proprietary plant cell-based expression technology. The success of our business is dependent upon the successful development and approval of our product and product candidates produced through this technology. Although taliglucerase alfa is produced through ProCellEx, the technology remains novel. Accordingly, the technology remains subject to certain risks. Mammalian cell-based protein expression systems have been used in connection with recombinant therapeutic protein expression for more than 20 years and are the subject of a wealth of data; in contrast, there is not a significant amount of data generated regarding plant cell-based protein expression and, accordingly, plant cell-based protein expression systems may be subject to unknown risks. In addition, the protein glycosilation pattern created by our protein expression system is not identical to the natural human glycosilation pattern and, although to date clinical data for up to five years of follow-up on taliglucerase alfa has not demonstrated any sign of any effect, the longer term effect of the protein glycosilation pattern created by our protein expression system on human patients, if any, is still unknown. Lastly, as our protein expression system is a new technology, we cannot always rely on existing equipment; rather, there is a need to design custom-made equipment and to generate specific growth media for the plant cells which may not be available at favorable prices, if at all. Any material problems with the technology underlying our plant cell-based protein expression system may have a material adverse effect on our business, results of operations and financial condition.
 
We currently depend heavily on the success of taliglucerase alfa, our first commercial product. Any failure to successfully commercialize taliglucerase alfa, or the experience of significant delays in doing so, will have a material adverse effect on our business, results of operations and financial condition.
 
We have invested a significant portion of our efforts and financial resources in the development of taliglucerase alfa. Our ability to generate product revenue, depends heavily on the successful development and commercialization of taliglucerase alfa. Pfizer holds an exclusive worldwide license to develop and commercialize taliglucerase alfa, except in Israel and Brazil. The successful commercialization of taliglucerase alfa will depend on several factors, including the following:
 
 	·	obtaining marketing approvals from additional regulatory authorities;	
 	·	successful completion of our ongoing studies of taliglucerase alfa;	
 
36	

 	
 	·	the successful audit of our facilities by additional regulatory authorities;	
 	·	maintaining the cGMP compliance of our manufacturing facility or establishing manufacturing arrangements with third parties;	
 	·	Pfizer’s efforts under the Pfizer Agreement;	
 	·	Fiocruz’s activities in Brazil;	
 	·	our marketing efforts in Israel;	
 	·	a continued acceptable safety and efficacy profile of taliglucerase alfa;	
 	·	the availability of reimbursement to patients from healthcare payors for taliglucerase alfa; and	
 	·	other risks described in these Risk Factors.	
 
Any failure to successfully commercialize taliglucerase alfa or the experience of significant delays in doing so will have a material adverse effect on our business, results of operations and financial condition.
 
If we are unable to develop and commercialize our other product candidates, our business will be adversely affected.
 
A key element of our strategy is to develop and commercialize a portfolio of new products in addition to taliglucerase alfa. We seek to do so through our internal research programs and strategic collaborations for the development of new products. Research programs to identify new product candidates require substantial technical, financial and human resources, whether or not any product candidates are ultimately identified. Our research programs may initially show promise in identifying potential product candidates, yet fail to yield product candidates for clinical development for many reasons, including the following:
 
 	·	a product candidate is not capable of being produced in commercial quantities at an acceptable cost, or at all;	
 	·	a product candidate may not be accepted by patients, the medical community or third-party payors;	
 	·	competitors may develop alternatives that render our product candidates obsolete;	
 	·	the research methodology used may not be successful in identifying potential product candidates; or	
 	·	a product candidate may on further study be shown to have harmful side effects or other characteristics that indicate it is unlikely to be effective or otherwise does not meet applicable regulatory approval.	
 
Any failure to develop or commercialize any of our other product candidates may have a material adverse effect on our business, results of operations and financial condition.
 
Clinical trials are very expensive, time-consuming and difficult to design and implement and may result in unforeseen costs which may have a material adverse effect on our business, results of operations and financial condition.
 
Human clinical trials are very expensive and difficult to design and implement, in part because they are subject to rigorous regulatory requirements. The clinical trial process is also time-consuming. Other than taliglucerase alfa, all of our other drug candidates are in the clinical, preclinical or research stages and will take at least several years to complete. Preliminary and initial results from a clinical trial do not necessarily predict final results, and failure can occur at any stage of the trials. We may encounter problems that cause us to abandon or repeat preclinical studies or clinical trials. Companies in the pharmaceutical and biotechnology industries have suffered significant setbacks in advanced clinical trials, even after obtaining promising results in earlier trials. Data obtained from tests are susceptible to varying interpretations which may delay, limit or prevent regulatory approval. Failure or delay in the commencement or completion of our clinical trials may be caused by several factors, including:
 
 	·	unforeseen safety issues;	
 	·	determination of dosing issues;	
 	·	lack of effectiveness during clinical trials;	
 	·	slower than expected rates of patient recruitment;	
 	·	inability to monitor patients adequately during or after treatment;	
 	·	inability or unwillingness of medical investigators and institutional review boards to follow our clinical protocols; and	
 	·	lack of sufficient funding to finance the clinical trials.	
 
Any failure or delay in commencement or completion of any clinical trials may have a material adverse effect on our business, results of operations and financial condition. In addition, we or the FDA or other regulatory authorities may suspend any clinical trial at any time if it appears that we are exposing participants in the trial to unacceptable safety or health risks or if the FDA or such other regulatory authorities, as applicable, find deficiencies in our IND submissions or the conduct of the trial. Any suspension of a clinical trial may have a material adverse effect on our business, results of operations and financial condition.
 
37	

 	

If the results of our clinical trials do not support our claims relating to any drug candidate or if serious side effects are identified, the completion of development of such drug candidate may be significantly delayed or we may be forced to abandon development altogether, which will significantly impair our ability to generate product revenues.
 
The results of our clinical trials with respect to any drug candidate might not support our claims of safety or efficacy, the effects of our drug candidates may not be the desired effects or may include undesirable side effects or the drug candidates may have other unexpected characteristics.  Further, success in preclinical testing and early clinical trials does not ensure that later clinical trials will be successful, and the results of later clinical trials may not replicate the results of prior clinical trials and preclinical testing.  The clinical trial process may fail to demonstrate that our drug candidates are safe for humans and effective for indicated uses.  In addition, our clinical trials may involve a specific and small patient population.  Results of early clinical trials conducted on a small patient population may not be indicative of future results.  Adverse or inconclusive results may cause us to abandon a drug candidate and may delay development of other drug candidates.  Any delay in, or termination of, our clinical trials will delay the filing of NDAs with the FDA, or other filings with other foreign regulatory authorities, and, ultimately, significantly impair our ability to commercialize our drug candidates and generate product revenues which would have a material adverse effect on our business, results of operations and financial condition.
 
We may find it difficult to enroll patients in our clinical trials, which could cause significant delays in the completion of such trials or may cause us to abandon one or more clinical trials.
 
Many of the diseases or disorders that our drug candidates are intended to treat are relatively rare and we expect only a subset of the patients with these diseases to be eligible for our clinical trials. Our clinical trials generally mandate that a patient cannot be involved in another clinical trial for the same indication. Therefore, subjects that participate in ongoing clinical trials for products that are competitive with our drug candidates are not available for our clinical trials. An inability to enroll a sufficient number of patients for any of our current or future clinical trials would result in significant delays or may require us to abandon one or more clinical trials altogether, which will have a material adverse effect on our business, results of operations and financial condition.
 
Patients may discontinue their participation in our clinical trials, which may negatively impact the results of these studies and extend the timeline for completion of our development programs.
 
Patients enrolled in our clinical trials may discontinue their participation at any time during the study as a result of a number of factors, including withdrawing their consent or experiencing adverse clinical events, which may or may not be judged related to our drug candidates under evaluation. The discontinuation of patients in any one of our studies may cause the results from that study not to be positive or to not support a filing for regulatory approval of the applicable drug candidate, which would have a material adverse effect on our business, results of operations and financial condition.
 
Because our clinical trials depend upon third-party researchers, the results of our clinical trials and such research activities are subject to delays and other risks which are, to a certain extent, beyond our control, which could impair our clinical development programs and our competitive position.
 
We depend upon independent investigators and collaborators, such as universities and medical institutions, to conduct our preclinical and clinical trials. These collaborators are not our employees, and we cannot control the amount or timing of resources that they devote to our clinical development programs. The investigators may not assign as great a priority to our clinical development programs or pursue them as diligently as we would if we were undertaking such programs directly. If outside collaborators fail to devote sufficient time and resources to our clinical development programs, or if their performance is substandard, the approval of our NDA and other marketing applications, and our introduction of new drugs, if any, may be delayed which could impair our clinical development programs and would have a material adverse effect on our business and results of operations. The collaborators may also have relationships with other commercial entities, some of whom may compete with us. If our collaborators also assist our competitors, our competitive position could be harmed.
 
The manufacture of our products is an exacting and complex process, and if we or one of our materials suppliers encounter problems manufacturing our products, it will have a material adverse effect on our business and results of operations.

The FDA and foreign regulators require manufacturers to register manufacturing facilities. The FDA and foreign regulators also inspect these facilities to confirm compliance with cGMP or similar requirements that the FDA or foreign regulators establish. We or our materials suppliers may face manufacturing or quality control problems causing product production and shipment delays or a situation where we or the supplier may not be able to maintain compliance with the FDA’s cGMP requirements, or those of foreign regulators, necessary to continue manufacturing our drug candidates. Any failure to comply with cGMP requirements or other FDA or foreign regulatory requirements could adversely affect our clinical research activities and our ability to market and develop our products. To date, our current facility has passed audits by the FDA, the Israeli MOH, ANVISA and the IMB on behalf of the EMA but remains subject to audit by other foreign regulatory authorities. There can be no assurance that we will be able to comply with FDA or foreign regulatory manufacturing requirements for our current facility or any facility we may establish in the future, which would have a material adverse effect on our business, results of operations and financial condition.
 
We rely on third parties for final processing of taliglucerase alfa and our other product candidates, which exposes us to a number of risks that may delay development, regulatory approval and commercialization of taliglucerase alfa and our other product candidates or result in higher product costs.
 
We have no experience in the final filling and freeze drying steps of the drug manufacturing process. We have engaged a European contract manufacturer to act as an additional source of fill and finish activities for taliglucerase alfa and have engaged other parties for our other product candidates. We currently rely primarily on other third-party contractors to perform the final manufacturing steps for taliglucerase alfa on a commercial scale. We may be unable to identify manufacturers and/or replacement manufacturers on acceptable terms or at all because the number of potential manufacturers is limited and the FDA and other regulatory authorities, as applicable, must approve any manufacturer and/or replacement manufacturer, including us, and we or any such third party manufacturer might be unable to formulate and manufacture our drug products in the volume and of the quality required to meet our clinical and commercial needs. If we engage any contract manufacturers, such manufacturers may not perform as agreed or may not remain in the contract manufacturing business for the time required to supply our clinical or commercial needs. In addition, contract manufacturers are subject to the rules and regulations of the FDA and comparable foreign regulatory authorities and face the risk that any of those authorities may find that they are not in compliance with applicable regulations. Each of these risks could delay our clinical trials, the approval, if any, of taliglucerase alfa and our other potential drug candidates by the FDA and other regulatory authorities, or the commercialization of taliglucerase alfa and our other drug candidates or could result in higher product costs or otherwise deprive us of potential product revenues.
 
Developments by competitors may render our products or technologies obsolete or non-competitive which would have a material adverse effect on our business, results of operations and financial condition.
 
We compete against fully integrated pharmaceutical companies and smaller companies that are collaborating with larger pharmaceutical companies, academic institutions, government agencies and other public and private research organizations. Our drug candidates will have to compete with existing therapies and therapies under development by our competitors. In addition, our commercial opportunities may be reduced or eliminated if our competitors develop and market products that are less expensive, more effective or safer than our drug products. Other companies have drug candidates in various stages of preclinical or clinical development to treat diseases for which we are also seeking to develop drug products. Some of these potential competing drugs are further advanced in development than our drug candidates and may be commercialized earlier. Even if we are successful in developing effective drugs, our products may not compete successfully with products produced by our competitors.
 
We specifically face competition from companies with approved treatments of Gaucher disease. In addition to ELELYSO, there are two other ERTs for the treatment of Gaucher disease; Cerezyme and VPRIV. To a much lesser extent, we also compete with Actelion. In addition, Genzyme is developing Eliglustat which is in the late stages of clinical development and was the subject of a phase III clinical trial that was completed in 2013. Eliglustat is a small molecule, oral drug which is being developed for the treatment of Gaucher disease.
 
There are two approved ERTs for the treatment of Fabry disease; Fabrazyme and Replagal. Fabrazyme is available in the United States and the European Union. Replagal is available in the European Union. In 2012, Shire elected to withdraw its BLA for Replagal in the United States. In addition, we are aware of other clinical stage, early clinical stage and experimental drugs which are being developed for the treatment of Fabry disease.
 
We also face competition from companies that are developing other platforms for the expression of recombinant therapeutic pharmaceuticals. We are aware of companies that are developing alternative technologies to develop and produce therapeutic proteins in anticipation of the expiration of certain patent claims covering marketed proteins. Competitors developing alternative expression technologies include Crucell N.V. (which was acquired by Johnson & Johnson during 2010), Shire and GlycoFi, Inc. (which was acquired by Merck & Co. Inc.). Other companies are developing alternate plant-based technologies, include iBio, Medicago and Greenovation Biotech GmbH, none of which are cell-based. Rather, such companies base their product development on transgenic plants or whole plants.
 
39	

 	
  
Several biogeneric companies are pursuing the opportunity to develop and commercialize follow-on versions of other currently marketed biologic products, including growth factors, hormones, enzymes, cytokines and monoclonal antibodies, which are areas that interest us. These companies include, among others, Novartis AG/Sandoz Pharmaceuticals, BioGeneriX AG, Stada Arzneimittel AG, BioPartners GmbH and Teva.
 
Most of our competitors, either alone or together with their collaborative partners, operate larger research and development programs, staff and facilities and have substantially greater financial resources than we do, as well as significantly greater experience in:
 
 	·	developing drugs;	
 	·	undertaking preclinical testing and human clinical trials;	
 	·	obtaining marketing approvals from the FDA and other regulatory authorities;	
 	·	formulating and manufacturing drugs; and	
 	·	launching, marketing and selling drugs.	
 
These organizations also compete with us to attract qualified personnel, acquisitions and joint ventures candidates and for other collaborations. Activities of our competitors may impose unanticipated costs on our business which would have a material adverse effect on our business, results of operations and financial condition.
 
If we in-license drug candidates, we may delay or otherwise adversely affect the development of our existing drug candidates, which may negatively impact our business, results of operations and financial condition.
 
In addition to our own internally developed drug candidates, we proactively seek opportunities to in-license and advance other drug candidates that are strategic and have value-creating potential to take advantage of our development know-how and technology. If we in-license any additional drug candidate, our capital requirements may increase significantly. In addition, in-licensing additional drug candidates may place a strain on the time of our existing personnel, which may delay or otherwise adversely affect the development of our existing drug candidates or cause us to re-prioritize our drug pipeline if we do not have the necessary capital resources to develop all of our drug candidates, which may delay the development of our drug candidates and materially and adversely impact our business, results of operations and financial condition.
 
If we are unable to successfully manage our growth, there could be a material adverse impact on our business, results of operations and financial condition.
 
We have grown rapidly and expect to continue to grow. To manage our anticipated future growth, we must continue to implement and improve our managerial, operational and financial systems, expand our facilities and continue to recruit and train additional qualified personnel. Due to our limited resources, we may not be able to effectively manage the expansion of our operations or recruit and train additional qualified personnel. The expansion of our operations may lead to significant costs and may divert our management and business development resources. Any inability on the part of our management to manage growth could delay the execution of our business plans or disrupt our operations. If we are unable to manage our growth effectively, we may not use our resources in an efficient manner, which may delay the development of our drug candidates and materially and adversely impact our business, results of operations and financial condition.
 
If we acquire companies, products or technologies, we may face integration risks and costs associated with those acquisitions that could negatively impact our business, results of operations and financial condition.
 
If we are presented with appropriate opportunities, we may acquire or make investments in complementary companies, products or technologies. We may not realize the anticipated benefit of any acquisition or investment. If we acquire companies or technologies, we will face risks, uncertainties and disruptions associated with the integration process, including difficulties in the integration of the operations of an acquired company, integration of acquired technology with our products, diversion of our management’s attention from other business concerns, the potential loss of key employees or customers of the acquired business and impairment charges if future acquisitions are not as successful as we originally anticipate. In addition, our operating results may suffer because of acquisition-related costs or amortization expenses or charges relating to acquired intangible assets. Any failure to successfully integrate other companies, products or technologies that we may acquire may have a material adverse effect on our business and results of operations. Furthermore, we may have to incur debt or issue equity securities to pay for any additional future acquisitions or investments, the issuance of which could be dilutive to our existing shareholders.

We depend upon key employees and consultants in a competitive market for skilled personnel. If we are unable to attract and retain key personnel, it could adversely affect our ability to develop and market our products.
 
We are highly dependent upon the principal members of our management team, especially our President and Chief Executive Officer, David Aviezer, Ph.D., as well as the Interim Chairman of our Board of Directors, Zeev Bronfeld, our other directors, our scientific advisory board members, consultants and collaborating scientists. Many of these people have been involved with us for many years and have played integral roles in our progress, and we believe that they will continue to provide value to us. A loss of any of these personnel may have a material adverse effect on aspects of our business, clinical development and regulatory programs. We have employment agreements with Dr. Aviezer and five other officers that may be terminated by us or the applicable officer at any time with varying notice periods of 60 to 90 days. Although these employment agreements generally include non-competition covenants, the applicable noncompetition provisions can be difficult and costly to monitor and enforce. The loss of any of these persons’ services may adversely affect our ability to develop and market our products and obtain necessary regulatory approvals. Further, we do not maintain key-man life insurance.
 
We also depend in part on the continued service of our key scientific personnel and our ability to identify, hire and retain additional personnel, including marketing and sales staff. We experience intense competition for qualified personnel, and the existence of non-competition agreements between prospective employees and their former employers may prevent us from hiring those individuals or subject us to suit from their former employers. While we attempt to provide competitive compensation packages to attract and retain key personnel, many of our competitors are likely to have greater resources and more experience than we have, making it difficult for us to compete successfully for key personnel.
 
Our collaborations with outside scientists and consultants may be subject to restriction and change.
 
We work with medical experts, chemists, biologists and other scientists at academic and other institutions, and consultants who assist us in our research, development, regulatory and commercial efforts, including the members of our scientific advisory board. These scientists and consultants have provided, and we expect that they will continue to provide, valuable advice regarding our programs. These scientists and consultants are not our employees, may have other commitments that would limit their future availability to us and typically will not enter into non-compete agreements with us. If a conflict of interest arises between their work for us and their work for another entity, we may lose their services. In addition, we will be unable to prevent them from establishing competing businesses or developing competing products. For example, if a key scientist acting as a principal investigator in any of our clinical trials identifies a potential product or compound that is more scientifically interesting to his or her professional interests, his or her availability to remain involved in our clinical trials could be restricted or eliminated, which may have a material adverse effect on our business, financial condition and results of operations.
 
Under current U.S. and Israeli law, we may not be able to enforce employees’ covenants not to compete and therefore may be unable to prevent our competitors from benefiting from the expertise of some of our former employees.
 
We have entered into non-competition agreements with substantially all of our employees. These agreements prohibit our employees, if they cease working for us, from competing directly with us or working for our competitors for a limited period. Under current U.S. and Israeli law, we may be unable to enforce these agreements against most of our employees and it may be difficult for us to restrict our competitors from gaining the expertise our former employees gained while working for us. If we cannot enforce our employees’ non-compete agreements, we may be unable to prevent our competitors from benefiting from the expertise of our former employees, which may have a material adverse effect on our business, financial condition and results of operations.
 
If product liability claims are brought against us, it may result in reduced demand for our products and product candidates or damages that exceed our insurance coverage.
 
The clinical testing, marketing and use of our products and product candidates exposes us to product liability claims if the use or misuse of those products or product candidates cause injury or disease, or results in adverse effects. Use of our products or product candidates, whether in clinical trials or post approval, could result in product liability claims. We presently carry clinical trial liability insurance with coverages of up to $10.0 million per occurrence and $10.0 million in the aggregate, an amount we consider reasonable and customary. However, this insurance coverage includes various deductibles, limitations and exclusions from coverage, and in any event might not fully cover any potential claims. We may need to obtain additional clinical trial liability coverage prior to initiating additional clinical trials. We expect to obtain product liability insurance coverage before commercialization of our product candidates; however, such insurance is expensive and insurance companies may not issue this type of insurance when we need it. We may not be able to obtain adequate insurance in the future at an acceptable cost. Any product liability claim, even one that was not in excess of our insurance coverage or one that is meritless and/or unsuccessful, may adversely affect our cash available for other purposes, such as research and development, which may have a material adverse effect on our business, results of operations and financial condition. Product liability claims, even if without merit, may result in reduced demand for our products, if approved, which would have a material adverse effect on our business, financial condition and results of operations. In addition, the existence of a product liability claim could affect the market price of our common stock.

Reforms in the healthcare industry and the uncertainty associated with pharmaceutical pricing, reimbursement and related matters could adversely affect the marketing, pricing and demand for our products, if approved.
 
Increasing healthcare expenditures have been the subject of considerable public attention in the United States. Both private and government entities are seeking ways to reduce or contain healthcare costs. Numerous proposals that would result in changes in the U.S. healthcare system have been introduced or proposed in the U.S. Congress and in some state legislatures within the United States, including reductions in the pricing of prescription products and changes in the levels at which consumers and healthcare providers are reimbursed for purchases of pharmaceutical products. Legislation passed in recent years has imposed certain changes to the way in which drugs, including our product candidates, are covered and reimbursed in the United States. For example, federal legislation and regulations have implemented new reimbursement methodologies for certain drugs, created a voluntary prescription drug benefit, Medicare Part D, and have imposed significant revisions to the Medicaid Drug Rebate Program. The PPACA imposes yet additional changes to these programs. We believe that legislation that reduces reimbursement for our product candidates could adversely impact how much or under what circumstances healthcare providers will prescribe or administer our products, if approved. This could materially and adversely impact our business by reducing our ability to generate revenue, raise capital, obtain additional collaborators and market our products, if approved. In addition, we believe the increasing emphasis on managed care in the United States has and will continue to put pressure on the price and usage of pharmaceutical products, which may adversely impact product sales, upon approval, if at all.
 
Governments outside the United States tend to impose strict price controls and reimbursement approval policies, which may adversely affect our prospects for generating revenue.
 
In some countries, particularly European Union member states, the pricing of prescription pharmaceuticals is subject to governmental control. In these countries, pricing negotiations with governmental authorities can take considerable time (six to 12 months or longer) after the receipt of marketing approval for a product. To obtain reimbursement or pricing approval in some countries with respect to any product candidate that achieves regulatory approval, we may be required to conduct a clinical trial that compares the cost-effectiveness of our product candidate to other available therapies. If reimbursement of our products upon approval, if at all, is unavailable or limited in scope or amount, or if pricing is set at unsatisfactory levels, our prospects for generating revenue, if any, could be adversely affected which would have a material adverse effect on our business, results of operations and financial condition. Further, if we achieve regulatory approval of any product, we must successfully negotiate product pricing for such product in individual countries. As a result, the pricing of our products, if approved, in different countries may vary widely, thus creating the potential for third-party trade in our products in an attempt to exploit price differences between countries. This third-party trade of our products could undermine our sales in markets with higher prices which could have a material adverse effect on our business, results of operations and financial condition.
 
Our ability to utilize net operating loss carryforwards may be limited.
 
The net operating loss carryforwards, or “NOLs”, of the Company as of December 31, 2013, equal to approximately $15.3 million, may be restricted under Section 382 of the Internal Revenue Code of 1986, as amended, or the “Code.” Section 382 of the Code imposes limitations on a corporation’s ability to utilize NOLs to offset taxable income if the corporation experiences an “ownership change.” In general terms, an “ownership change” may result from transactions increasing the ownership of certain stockholders in the stock of a corporation by more than 50% over a three-year period. In the event that an ownership change has occurred, or were to occur, utilization of our NOLs would be subject to an annual limitation under Section 382, which is generally the fair market value of the pre-change entity multiplied by the long-term tax exempt rate, which is published monthly by the Internal Revenue Service.
 
We are a holding company with no operations of our own.
 
We are a holding company with no operations of our own. Accordingly, our ability to conduct our operations, service any debt that we may incur in the future and pay dividends, if any, is dependent upon the earnings from the business conducted by Protalix Ltd. The distribution of those earnings or advances or other distributions of funds by our subsidiary to us, as well as our receipt of such funds, are contingent upon the earnings of our subsidiary and are subject to various business considerations and U.S. and Israeli law. If Protalix Ltd. is unable to make sufficient distributions or advances to us, or if there are limitations on our ability to receive such distributions or advances, we may not have the cash resources necessary to conduct our corporate operations which would have a material adverse effect on our business, results of operations and financial condition.

Risks Related to Regulatory Matters
 
We are subject to extensive governmental regulation including the requirement of FDA or comparable approval before our drug candidates may be marketed.
 
Both before and after approval of our drug candidates, we, our drug candidates, our suppliers, our contract manufacturers and our contract testing laboratories are subject to extensive regulation by the FDA or comparable foreign regulatory authorities. Failure to comply with applicable requirements of the FDA or comparable foreign regulatory authorities could result in, among other things, any of the following actions:
 
 	·	warning letters;	
 	·	fines and other monetary penalties;	
 	·	unanticipated expenditures;	
 	·	delays in the FDA’s or other foreign regulatory authorities’ approving, or the refusal of any regulatory authority to approve, any drug candidate;	
 	·	product recall or seizure;	
 	·	interruption of manufacturing or clinical trials;	
 	·	operating restrictions;	
 	·	injunctions; and	
 	·	criminal prosecutions.	
 
In addition to the approval requirements, other numerous and pervasive regulatory requirements apply, both before and after approval, to us, our drug candidates, and our suppliers, contract manufacturers, and contract laboratories. These include requirements related to:
 
 	·	testing;	
 	·	manufacturing;	
 	·	quality control;	
 	·	labeling;	
 	·	advertising;	
 	·	promotion;	
 	·	distribution;	
 	·	export;	
 	·	reporting to the FDA certain adverse experiences associated with use of the drug candidate; and	
 	·	obtaining additional approvals for certain modifications to the drug candidate or its labeling or claims.	
 
We also are subject to inspection by the FDA and comparable foreign regulatory authorities, to determine our compliance with regulatory requirements, as are our suppliers, contract manufacturers, and contract testing laboratories, and there can be no assurance that the FDA or any other comparable foreign regulatory authority, will not identify compliance issues that may disrupt production or distribution, or require substantial resources to correct. We may be required to make modifications to our manufacturing operations in response to these inspections which may require significant resources and may have a material adverse effect upon our business, results of operations and financial condition.
 
The approval process for any drug candidate may also be delayed by changes in government regulation, future legislation or administrative action or changes in policy of the FDA and comparable foreign authorities that occur prior to or during their respective regulatory reviews of such drug candidate. Delays in obtaining regulatory approvals with respect to any drug candidate may:
 
 	·	delay commercialization of, and our ability to derive product revenues from, such drug candidate;	
 	·	delay any regulatory-related milestone payments payable under outstanding collaboration agreements;	
 	·	require us to perform costly procedures with respect to such drug candidate; or	
 	·	otherwise diminish any competitive advantages that we may have with respect to such drug candidate.	
 
43	

 	
  
Delays in the approval process for any drug candidate may have a material adverse effect upon our business, results of operations and financial condition.
 
We may not obtain the necessary U.S., EMA or other worldwide regulatory approvals to commercialize our drug candidates in a timely manner, if at all, which would have a material adverse effect on our business, financial condition and results of operations.
 
We need FDA approval to commercialize our drug candidates in the United States, EMA approval to commercialize our drug candidates in the European Union and approvals from foreign regulators to commercialize our drug candidates elsewhere. In order to obtain FDA approval of any of our drug candidates, we must submit to the FDA an NDA or a Biologic License Application (BLA) demonstrating that the drug candidate is safe for humans and effective for its intended use. This demonstration requires significant research and animal tests, which are referred to as preclinical studies, as well as human tests, which are referred to as clinical trials. In the European Union, we must submit an MAA to the EMA. Satisfaction of the FDA’s, the EMA’s and foreign regulatory authorities’ regulatory requirements typically takes many years, depends upon the type, complexity and novelty of the drug candidate and requires substantial resources for research, development and testing. Taliglucerase alfa has been approved for marketing in the United States, Israel, Brazil, Mexico, Chile and Uruguay, and marketing applications are outstanding in other countries. Even if we comply with all the requests of regulatory authorities, the authorities may ultimately reject the marketing applications filed for taliglucerase alfa or that we file for our other product candidates in the future, if any, or we might not obtain regulatory clearance in a timely manner for taliglucerase alfa in certain countries or for any of our other drug candidates. Companies in the pharmaceutical and biotechnology industries have suffered significant setbacks in advanced or late-stage clinical trials, even after obtaining promising earlier trial results or in preliminary findings or other comparable authorities for such clinical trials.  Further, even if favorable testing data is generated by the clinical trials of a drug candidate, the applicable regulatory authority may not accept or approve the marketing application filed by a pharmaceutical or biotechnology company for the drug candidate. Failure to obtain approval of the FDA, EMA or comparable foreign authorities of any of our drug candidates in a timely manner, if at all, will severely undermine our business, financial condition and results of operation by reducing our potential marketable products and our ability to generate corresponding product revenues.
 
Our research and clinical efforts may not result in drugs that the FDA, EMA or foreign regulatory authorities consider safe for humans and effective for indicated uses, which would have a material adverse effect on our business, financial condition and results of operations.  After clinical trials are completed for any drug candidate, if at all, the FDA, EMA and foreign regulatory authorities have substantial discretion in the drug approval process of the drug candidate in their respective jurisdictions and may require us to conduct additional clinical testing or perform post-marketing studies which would cause us to incur additional costs. Incurring such costs may have a material adverse effect on our business, financial condition and results of operations.
 
We have only limited experience in regulatory affairs, and some of our drug candidates may be based on new technologies. These factors may affect our ability or the time we require to obtain necessary regulatory approvals.
 
We have only limited experience in filing and prosecuting the applications necessary to gain regulatory approvals for medical devices and drug candidates. Moreover, some of the drug candidates that are likely to result from our development programs may be based on new technologies that have not been extensively tested in humans. The regulatory requirements governing these types of drug candidates may be less well defined or more rigorous than for conventional products. As a result, we may experience a longer regulatory process in connection with obtaining regulatory approvals of any products that we develop.
 
If any of our other competitors are able to obtain orphan drug exclusivity for any products that are competitive with our products, we may be precluded from selling or obtaining approval of our competing products by the applicable regulatory authorities for a significant period of time.
 
In the United States, the European Union and other countries, a drug may be designated as having orphan drug status, subject to certain conditions. There can be no assurance that a drug candidate that receives orphan drug designation will receive orphan drug marketing exclusivity and more than one drug can have orphan designation for the same indication.
 
Foreign regulations regarding orphan drugs are similar to those in the United States but there are several conceptual differences. For example, the exclusivity period in the European Union is generally 10 years. The EMA/European Commission has granted orphan drug designation and exclusivity to VPRIV in the European Union. For this reason, CHMP has recommended that the EC not issue a Marketing Authorization for taliglucerase alfa in the European Union. Therefore, VPRIV has orphan market exclusivity in the European Union for a 10-year period commencing on its authorization in August 2010 which may have a material adverse effect on our business, results of operations and financial condition.
 
44	

 	
 
From time to time, we may apply to the FDA or any comparable foreign regulatory authority for orphan drug designation for any one or more of our drug candidates. None of our currently developed drug candidates have been designated as an orphan drug and there is no guarantee that the FDA or any other regulatory authority will grant such designation in the future. In addition, neither orphan drug designation nor orphan drug exclusivity prevents competitors from developing or marketing different drugs for that indication. Even if we obtain orphan drug exclusivity for one or more indications for one of our drug candidates, we may not be able to maintain the exclusivity. For example, if a competitive product that is the same drug or biologic as one of our drug candidates is shown to be clinically superior to the drug candidate, any orphan drug exclusivity granted to the drug candidate will not block the approval of the competitive product.
 
Risks Related to Intellectual Property Matters
 
If we fail to adequately protect or enforce our intellectual property rights or secure rights to third party patents, the value of our intellectual property rights would diminish and our business, competitive position and results of operations would suffer.
 
As of December 31, 2013, we had 89 pending patent applications and one joint pending patent application with a third party. However, the filing of a patent application does not mean that we will be issued a patent, or that any patent eventually issued will be as broad as requested in the patent application or sufficient to protect our technology. Any modification required to a current patent application may delay the approval of such patent application which would have a material adverse effect on our business, results of operations and financial condition. In addition, there are a number of factors that could cause our patents, if granted, to become invalid or unenforceable or that could cause our patent applications to not be granted, including known or unknown prior art, deficiencies in the patent application or the lack of originality of the technology. Our competitive position and future revenues will depend in part on our ability and the ability of our licensors and collaborators to obtain and maintain patent protection for our products, methods, processes and other technologies, to preserve our trade secrets, to prevent third parties from infringing on our proprietary rights and to operate without infringing the proprietary rights of third parties. We have filed U.S. and international patent applications for process patents, as well as composition of matter patents, for taliglucerase alfa and other product candidates. However, we cannot predict:
 
 	·	the degree and range of protection any patents will afford us against competitors and those who infringe upon our patents, including whether third parties will find ways to invalidate or otherwise circumvent our licensed patents;	
 	·	if and when patents will issue;	
 	·	whether or not others will obtain patents claiming aspects similar to those covered by our licensed patents and patent applications; or	
 	·	whether we will need to initiate litigation or administrative proceedings, which may be costly, and whether we win or lose.	
 
As of December 31, 2013, we hold, or have license rights to, 49 patents (including one joint patent). If patent rights covering our products or technologies are not sufficiently broad, they may not provide us with sufficient proprietary protection or competitive advantages against competitors with similar products and technologies. Furthermore, if the U.S. Patent and Trademark Office or foreign patent offices issue patents to us or our licensors, others may challenge the patents or circumvent the patents, or the patent office or the courts may invalidate the patents. Thus, any patents we own or license from or to third parties may not provide any protection against our competitors and those who infringe upon our patents.
 
Furthermore, the life of our patents is limited. The patents we hold relating to our ProCellEx protein expression system will expire in 2017 and 2025. If patents issue from other currently pending patent applications, those patents will expire between 2024 and 2031.
 
We rely on confidentiality agreements that could be breached and may be difficult to enforce which could have a material adverse effect on our business and competitive position.
 
Our policy is to enter agreements relating to the non-disclosure of confidential information with third parties, including our contractors, consultants, advisors and research collaborators, as well as agreements that purport to require the disclosure and assignment to us of the rights to the ideas, developments, discoveries and inventions of our employees and consultants while we employ them. However, these agreements can be difficult and costly to enforce. Moreover, to the extent that our contractors, consultants, advisors and research collaborators apply or independently develop intellectual property in connection with any of our projects, disputes may arise as to the proprietary rights to the intellectual property. If a dispute arises, a court may determine that the right belongs to a third party, and enforcement of our rights can be costly and unpredictable. In addition, we rely on trade secrets and proprietary know-how that we seek to protect in part by confidentiality agreements with our employees, contractors, consultants, advisors or others. Despite the protective measures we employ, we still face the risk that:
  
45	

 	
 
 	·	these agreements may be breached;	

 	·	these agreements may not provide adequate remedies for the applicable type of breach; or	
 	·	our trade secrets or proprietary know-how will otherwise become known.	
 
Any breach of our confidentiality agreements or our failure to effectively enforce such agreements would have a material adverse effect on our business and competitive position.
 
If we infringe the rights of third parties we could be prevented from selling products, forced to pay damages and required to defend against litigation which could result in substantial costs and may have a material adverse effect on our business, results of operations and financial condition.
 
We have not received to date any claims of infringement by any third parties. However, as our drug candidates progress into clinical trials and commercialization, if at all, our public profile and that of our drug candidates may be raised and generate such claims. Defending against such claims, and occurrence of a judgment adverse to us, could result in unanticipated costs and may have a material adverse effect on our business and competitive position. If our products, methods, processes and other technologies infringe the proprietary rights of other parties, we may incur substantial costs and we may have to:
 
 	·	obtain licenses, which may not be available on commercially reasonable terms, if at all;	
 	·	redesign our products or processes to avoid infringement;	
 	·	stop using the subject matter claimed in the patents held by others, which could cause us to lose the use of one or more of our drug candidates;	
 	·	defend litigation or administrative proceedings that may be costly whether we win or lose, and which could result in a substantial diversion of management resources; or	
 	·	pay damages.	
 
Any costs incurred in connection with such events or the inability to sell our products may have a material adverse effect on our business, results of operations and financial condition.
 
If we cannot meet requirements under our license agreements, we could lose the rights to our products, which could have a material adverse effect on our business.
 
We depend on licensing agreements with third parties to maintain the intellectual property rights to certain of our product candidates. Our license agreements require us to make payments and satisfy performance obligations in order to maintain our rights under these agreements. All of these agreements last either throughout the life of the patents that are the subject of the agreements, or with respect to other licensed technology, for a number of years after the first commercial sale of the relevant product.
 
In addition, we are responsible for the cost of filing and prosecuting certain patent applications and maintaining certain issued patents licensed to us. If we do not meet our obligations under our license agreements in a timely manner, we could lose the rights to our proprietary technology which could have a material adverse effect on our business, results of operations and financial condition.
 
Risks Relating to Our Operations in Israel
 
Potential political, economic and military instability in the State of Israel, where the majority of our senior management and our research and development facilities are located, may adversely affect our results of operations.
 
Our executive office and operations are located in the State of Israel. Accordingly, political, economic and military conditions in Israel directly affect our business. Since the State of Israel was established in 1948, a number of armed conflicts have occurred between Israel and its Arab neighbors. Any hostilities involving Israel or the interruption or curtailment of trade between Israel and its present trading partners, or a significant downturn in the economic or financial condition of Israel, could affect adversely our operations. Since October 2000 there have been increasing occurrences of terrorist violence. Ongoing and revived hostilities or other Israeli political or economic factors could harm our operations and product development and cause our revenues to decrease. Furthermore, several countries, principally those in the Middle East, still restrict business with Israel and Israeli companies. These restrictive laws and policies may limit seriously our ability to sell our products in these countries.
 
46	

 	
 
Although Israel has entered into various agreements with Egypt, Jordan and the Palestinian Authority, there have been times since October 2000 when Israel has experienced an increase in unrest and terrorist activity. The establishment in 2006 of a government in the Palestinian Authority by representatives of the Hamas militant group has created additional unrest and uncertainty in the region. In mid-2006, there was a war between Israel and the Hezbollah in Lebanon, resulting in thousands of rockets being fired from Lebanon up to 50 miles into Israel. Our current facilities are located in northern Israel, are in range of rockets that were fired from Lebanon into Israel during the war and suffered minimal damages during one of the rocket attacks. Starting in December 2008, for approximately three weeks, Israel engaged in an armed conflict with Hamas in the Gaza Strip. An armed conflict between Israel and Hamas in the Gaza Strip occurred again in November 2012. Our insurance policies do not cover us for the damages incurred in connection with these conflicts or for any resulting disruption in our operations. The Israeli government, as a matter of law, provides coverage for the reinstatement value of direct damages that are caused by terrorist attacks or acts of war; however, the government may cease providing such coverage or the coverage might not be enough to cover potential damages. If our facilities are damaged as a result of hostile action, our operations may be materially adversely affected.
 
In addition to the foregoing, since the end of 2010, numerous acts of protest and civil unrest have taken place in several countries in the Middle East and North Africa, many of which involved significant violence. The civil unrest in Egypt, which borders Israel, resulted in the resignation of its president Hosni Mubarak, and to significant changes to the country’s government. In Syria, also bordering Israel, large civilian protests have progressed into a civil war. The ultimate effect of these developments on the political and security situation in the Middle East and on Israel’s position within the region is not clear at this time.
 
Our operations may be disrupted by the obligations of our personnel to perform military service which could have a material adverse effect on our business.
 
Many of our male employees in Israel, including members of senior management, are obligated to perform up to one month (in some cases more) of annual military reserve duty until they reach the age of 45 and, in the event of a military conflict, could be called to active duty. Our operations could be disrupted by the absence of a significant number of our employees related to military service or the absence for extended periods of military service of one or more of our key employees. A disruption could have a material adverse effect on our business.
 
Because a certain portion of our expenses is incurred in New Israeli Shekels, or NIS, our results of operations may be seriously harmed by currency fluctuations and inflation.
 
We report our financial statements in U.S. dollars, our functional currency. Although most of our expenses are incurred in U.S. dollars, we pay a portion of our expenses in New Israeli Shekels, or NIS, and as a result, we are exposed to risk to the extent that the inflation rate in Israel exceeds the rate of devaluation of the NIS in relation to the U.S. dollar or if the timing of these devaluations lags behind inflation in Israel. In that event, the U.S. dollar cost of our operations in Israel will increase and our U.S. dollar-measured results of operations will be adversely affected. To the extent that the value of the NIS increases against the dollar, our expenses on a dollar cost basis increase. Our operations also could be adversely affected if we are unable to guard against currency fluctuations in the future. To date, we have not engaged in hedging transactions. In the future, we may enter into currency hedging transactions to decrease the risk of financial exposure from fluctuations in the exchange rate of the U.S. dollar against the NIS. These measures, however, may not adequately protect us from material adverse effects.
 
The tax benefits available to us require that we meet several conditions and may be terminated or reduced in the future, which would increase our taxes.
 
We are able to take advantage of tax exemptions and reductions resulting from the “Approved Enterprise” status of our facilities in Israel. To remain eligible for these tax benefits, we must continue to meet certain conditions, including making specified investments in property and equipment, and financing at least 30% of such investments with share capital. If we fail to meet these conditions in the future, the tax benefits would be canceled and we may be required to refund any tax benefits we already have enjoyed. These tax benefits are subject to investment policy by the Investment Center and may not be continued in the future at their current levels or at any level. In recent years the Israeli government has reduced the benefits available and has indicated that it may further reduce or eliminate some of these benefits in the future. The termination or reduction of these tax benefits or our inability to qualify for additional “Approved Enterprise” approvals may increase our tax expenses in the future, which would reduce our expected profits and adversely affect our business and results of operations. Additionally, if we increase our activities outside of Israel, for example, by future acquisitions, such increased activities generally may not be eligible for inclusion in Israeli tax benefit programs.

The Israeli government grants we have received for certain research and development expenditures restrict our ability to manufacture products and transfer technologies outside of Israel and require us to satisfy specified conditions. If we fail to satisfy these conditions, we may be required to refund grants previously received together with interest and penalties which could have a material adverse effect on our business and results of operations.
 
Our research and development efforts have been financed, in part, through grants that we have received from the OCS. We, therefore, must comply with the requirements of the Research Law.
 
Under the Research Law we are prohibited from manufacturing products developed using these grants outside of the State of Israel without special approvals, although the Research Law does enable companies to seek prior approval for conducting manufacturing activities outside of Israel without being subject to increased royalties. We may not receive the required approvals for any proposed transfer of manufacturing activities. Even if we do receive approval to manufacture products developed with government grants outside of Israel, we may be required to pay an increased total amount of royalties (possibly up to 300% of the grant amounts plus interest), depending on the manufacturing volume that is performed outside of Israel, as well as at a possibly increased royalty rate. This restriction may impair our ability to outsource manufacturing or engage in similar arrangements for those products or technologies.
 
Additionally, under the Research Law, we are prohibited from transferring the OCS-financed technologies and related intellectual property rights outside of the State of Israel, except under limited circumstances and only with the approval of the OCS’ Research Committee. We may not receive the required approvals for any proposed transfer and, if received, we may be required to pay the OCS a portion of the consideration that we receive upon any sale of such technology by a non-Israeli entity. The scope of the support received, the royalties that we have already paid to the OCS, the amount of time that has elapsed between the date on which the know-how was transferred and the date on which the OCS grants were received and the sale price and the form of transaction will be taken into account in order to calculate the amount of the payment to the OCS. Approval of the transfer of technology to residents of the State of Israel is required, and may be granted in specific circumstances only if the recipient abides by the provisions of applicable laws, including the restrictions on the transfer of know-how and the obligation to pay royalties. No assurance can be made that approval to any such transfer, if requested, will be granted.
 
These restrictions may impair our ability to sell our technology assets or to outsource manufacturing outside of Israel. The restrictions will continue to apply for a certain period of time even after we have repaid the full amount of royalties payable for the grants. For the years ended December 31, 2012 and 2013, we recorded grants totaling $4.1 million and $3.4 million from the OCS, respectively. The grants represent 11.1% and 10.4%, respectively, of our gross research and development expenditures for the years ended December 31, 2012 and 2013. If we fail to satisfy the conditions of the Research Law, we may be required to refund certain grants previously received together with interest and penalties, and may become subject to criminal charges, any of which could have a material adverse effect on our business, results of operations and financial condition.
 
Investors may have difficulties enforcing a U.S. judgment, including judgments based upon the civil liability provisions of the U.S. federal securities laws against us, our executive officers and most of our directors or asserting U.S. securities laws claims in Israel.
 
Most of our directors and none of our officers are residents of the United States, and most of their assets and our assets are located outside the United States. Service of process upon our non-U.S. resident directors and officers and enforcement of judgments obtained in the United States against us, some of our directors and executive officers may be difficult to obtain within the United States. We have been informed by our legal counsel in Israel that investors may find it difficult to assert claims under U.S. securities laws in original actions instituted in Israel or obtain a judgment based on the civil liability provisions of U.S. federal securities laws against us, our officers and our directors. Israeli courts may refuse to hear a claim based on a violation of U.S. securities laws against us or our officers and directors because Israel is not the most appropriate forum to bring such a claim. In addition, even if an Israeli court agrees to hear a claim, it may determine that Israeli law and not U.S. law is applicable to the claim. If U.S. law is found to be applicable, the content of applicable U.S. law must be proved as a fact which can be a time-consuming and costly process. Certain matters of procedure will also be governed by Israeli law. There is little binding case law in Israel addressing the matters described above.
 
Israeli courts might not enforce judgments rendered outside Israel which may make it difficult to collect on judgments rendered against us. Subject to certain time limitations, an Israeli court may declare a foreign civil judgment enforceable only if it finds that:
 
48	

 	
  
 	·	the judgment was rendered by a court which was, according to the laws of the state of the court, competent to render the judgment;	

 	·	the judgment may no longer be appealed;	
 	·	the obligation imposed by the judgment is enforceable according to the rules relating to the enforceability of judgments in Israel and the substance of the judgment is not contrary to public policy; and	
 	·	the judgment is executory in the state in which it was given.	
 
Even if these conditions are satisfied, an Israeli court will not enforce a foreign judgment if it was given in a state whose laws do not provide for the enforcement of judgments of Israeli courts (subject to exceptional cases) or if its enforcement is likely to prejudice the sovereignty or security of the State of Israel. An Israeli court also will not declare a foreign judgment enforceable if:
 
 	·	the judgment was obtained by fraud;	
 	·	there is a finding of lack of due process;	
 	·	the judgment was rendered by a court not competent to render it according to the laws of private international law in Israel;	
 	·	the judgment is at variance with another judgment that was given in the same matter between the same parties and that is still valid; or	
 	·	at the time the action was brought in the foreign court, a suit in the same matter and between the same parties was pending before a court or tribunal in Israel.

Risks Related to Investing in our Common Stock
 
The market price of our common stock may fluctuate significantly.
 
The market price of our common stock may fluctuate significantly in response to numerous factors, some of which are beyond our control, such as:
 
 	·	Pfizer’s and our commercialization efforts for ELELYSO;	
 	·	the results of our ongoing studies regarding our product candidates;	
 	·	announcements regarding partnerships or collaborations by us or our competitors;	
 	·	developments concerning intellectual property rights and regulatory approvals;	
 	·	the announcement of new products or product enhancements by us or our competitors;	
 	·	variations in our and our competitors’ results of operations;	
 	·	changes in earnings estimates or recommendations by securities analysts;	
 	·	developments in the biotechnology industry; and	
 	·	general market conditions and other factors, including factors unrelated to our operating performance.	
 
Further, stock markets in general, and the market for biotechnology companies in particular, have recently experienced price and volume fluctuations. Continued market fluctuations could result in extreme volatility in the price of our common stock, which could cause a decline in the value of our common stock. Price volatility of our common stock may be worse if the trading volume of our common stock is low. We have not paid, and do not expect to pay, any cash dividends on our common stock as any earnings generated from future operations will be used to finance our operations. As a result, investors will not realize any income from an investment in our common stock until and unless their shares are sold at a profit.
 
Future sales of our common stock could reduce our stock price.
 
The market price of our common stock could drop significantly if our existing shareholders sell a large number of shares of our common stock or are perceived by the market as intending to sell them. All of our outstanding shares of our common stock are freely tradable without restriction or further registration under the federal securities laws, unless owned by our affiliates. At December 31, 2013, there were unvested restricted shares and options to purchase common stock issued and outstanding covering 7,036,531 shares of our common stock with a weighted average exercise price of $3.83 per share. Also at December 31, 2013, there were 215,378 shares of common stock remaining available for future for issuance in connection with future grants of incentives under our amended 2006 stock incentive plan.

Servicing our debt requires a significant amount of cash, and we may not have sufficient cash flow from our business to pay our debt.
 
Our ability to pay interest on, or to make any scheduled payment of the principal of, the Notes, depends on our future performance, which is subject to economic, financial, competitive and other factors beyond our control. Our business may not generate cash flow from operations in the future sufficient to service our debt and make necessary expenditures. If we are unable to generate such cash flow, we may be required to adopt one or more alternatives, such as selling assets, restructuring debt or obtaining additional equity capital on terms that may be onerous or highly dilutive. Our ability to refinance our indebtedness will depend on the capital markets and our financial condition at such time. If we raise additional debt, it would increase our interest expense, leverage and operating and financial costs. In addition, the terms of the indenture governing the Notes and the agreements governing future indebtedness may restrict us from adopting any of these alternatives. We may not be able to engage in any of these activities or engage in these activities on desirable terms, which could result in a default on our debt obligations. The failure to generate sufficient cash flow or to effect any of these alternatives could significantly adversely affect the value of the Notes and our ability to pay amounts due under the Notes.
 
Our significant level of indebtedness could adversely affect our business, financial condition and results of operations and prevent us from fulfilling our obligations under the Notes and our other indebtedness.
 
The outstanding Notes represent a significant amount of indebtedness and substantial debt service requirements. We may also incur additional indebtedness to meet future financing needs. Our substantial indebtedness could have material adverse effects on our business, financial condition and results of operations. For example, it could:
 
 	·	make it more difficult for us to satisfy our financial obligations, including with respect to the Notes;	
 	·	result in an event of default if we fail to comply with the financial and other restrictive covenants contained in agreements governing any future indebtedness, which event of default could result in all of our debt becoming immediately due and payable;	
 	·	increase our vulnerability to general adverse economic, industry and competitive conditions;	
 	·	reduce the availability of our cash flow to fund working capital, capital expenditures, acquisitions and other general corporate purposes because we will be required to dedicate a substantial portion of our cash flow from operations to the payment of principal and interest on our indebtedness;	
 	·	limit our flexibility in planning for, or reacting to, and increasing our vulnerability to changes in our business, the industry in which we operate and the general economy;	
 	·	prevent us from raising funds necessary to purchase Notes surrendered to us by holders upon a fundamental change (as described in the indenture governing the Notes), which failure would result in an event of default with respect to the Notes;	
 	·	place us at a competitive disadvantage compared to our competitors that have less indebtedness or are less highly leveraged and that, therefore, may be able to take advantage of opportunities that our debt levels or leverage prevent us from exploiting; and	
 	·	limit our ability to obtain additional financing.	
 
Each of these factors may have a material and adverse effect on our business, financial condition and results of operations and our ability to meet our payment obligations under the Notes and our other indebtedness. Our ability to make payments with respect to the Notes and to satisfy any other debt obligations will depend on our future operating performance and our ability to generate significant cash flow in the future, which will be affected by prevailing economic conditions and financial, business, competitive, legislative and regulatory factors as well as other factors affecting our company and industry, many of which are beyond our control.
 
Any conversion of the Notes will dilute the ownership interest of our existing stockholders, including holders who had previously converted their notes.
 
The conversion of some or all of the Notes will dilute the ownership interests of our existing stockholders. Any sales in the public market of our common stock issuable upon such conversion could adversely affect prevailing market prices of our common stock. In addition, the existence of the Notes may encourage short selling by market participants because the conversion of the Notes could depress the price of our common stock.
 
Our common stock is listed for trade on more than one stock exchange, and this may result in price variations.
 
Our common stock is listed for trade on both the NYSE MKT and the TASE. Dual-listing may result in price variations between the exchanges due to a number of factors. First, our common stock is traded in U.S. dollars on the NYSE MKT and in NIS on the TASE. In addition, the exchanges are open for trade at different times of the day and on different days. For example, the TASE opens generally during Israeli business hours, Sunday through Thursday while the NYSE MKT opens generally during U.S. business hours, Monday through Friday. The two exchanges also have differing vacation schedules. Differences in the trading schedules, as well as volatility in the exchange rate of the two currencies, among other factors, may result different trading prices for our common stock on the two exchanges. Other external influences may have different effects on the trading price of our common stock on the two exchanges.
 
50	

 	
  
Directors, executive officers, principal shareholders and affiliated entities own a significant percentage of our capital stock, and they may make decisions that an investor may not consider to be in the best interests of our shareholders.
 
Our directors, executive officers, principal shareholders and affiliated entities beneficially own, in the aggregate, approximately 50% of our outstanding common stock. As a result, if some or all of them acted together, they would have the ability to exert substantial influence over the election of our Board of Directors and the outcome of issues requiring approval by our shareholders. This concentration of ownership may have the effect of delaying or preventing a change in control of our company that may be favored by other shareholders. This could prevent the consummation of transactions favorable to other shareholders, such as a transaction in which shareholders might otherwise receive a premium for their shares over current market prices.
 
Failure to maintain effective internal controls in accordance with Section 404 of the Sarbanes-Oxley Act could have a material adverse effect on our business and operating results. In addition, current and potential shareholders could lose confidence in our financial reporting, which could have a material adverse effect on the price of our common stock.
 
Effective internal controls are necessary for us to provide reliable financial reports and effectively prevent fraud. If we cannot provide reliable financial reports or prevent fraud, our results of operation could be harmed.
 
Section 404 of the Sarbanes-Oxley Act of 2002 requires annual management assessments of the effectiveness of our internal controls over financial reporting and a report by our independent registered public accounting firm addressing these assessments. We continuously monitor our existing internal controls over financial reporting systems to confirm that they are compliant with Section 404, and we may identify deficiencies that we may not be able to remediate in time to meet the deadlines imposed by the Sarbanes-Oxley Act. This process may divert internal resources and will take a significant amount of time and effort to complete.
 
If, at any time, it is determined that we are not in compliance with Section 404, we may be required to implement new internal control procedures and reevaluate our financial reporting. We may experience higher than anticipated operating expenses as well as increased independent auditor fees during the implementation of these changes and thereafter. Further, we may need to hire additional qualified personnel. If we fail to maintain the adequacy of our internal controls, as such standards are modified, supplemented or amended from time to time, we may not be able to conclude on an ongoing basis that we have effective internal controls over financial reporting in accordance with Section 404 of the Sarbanes-Oxley Act, which could result in our being unable to obtain an unqualified report on internal controls from our independent auditors. Failure to maintain an effective internal control environment could also cause investors to lose confidence in our reported financial information, which could have a material adverse effect on the price of our common stock.
 
Compliance with changing regulation of corporate governance and public disclosure may result in additional expenses, divert management’s attention from operating our business which could have a material adverse effect on our business.
 
There have been other changing laws, regulations and standards relating to corporate governance and public disclosure in addition to the Sarbanes-Oxley Act, as well as new regulations promulgated by the Commission and rules promulgated by the national securities exchanges, including the NYSE MKT and the NASDAQ. These new or changed laws, regulations and standards are subject to varying interpretations in many cases due to their lack of specificity, and as a result, their application in practice may evolve over time as new guidance is provided by regulatory and governing bodies, which could result in continuing uncertainty regarding compliance matters and higher costs necessitated by ongoing revisions to disclosure and governance practices. As a result, our efforts to comply with evolving laws, regulations and standards are likely to continue to result in increased general and administrative expenses and a diversion of management time and attention from revenue-generating activities to compliance activities. Our board members, Chief Executive Officer and Chief Financial Officer could face an increased risk of personal liability in connection with the performance of their duties. As a result, we may have difficulty attracting and retaining qualified board members and executive officers, which could have a material adverse effect on our business. If our efforts to comply with new or changed laws, regulations and standards differ from the activities intended by regulatory or governing bodies, we may incur additional expenses to comply with standards set by regulatory authorities or governing bodies which would have a material adverse effect on our business, results of operations and financial condition.

The issuance of preferred stock or additional shares of common stock could adversely affect the rights of the holders of shares of our common stock.
 
Our Board of Directors is authorized to issue up to 100,000,000 shares of preferred stock without any further action on the part of our shareholders. Our Board of Directors has the authority to fix and determine the voting rights, rights of redemption and other rights and preferences of preferred stock. Currently, we have no shares of preferred stock outstanding.
 
Our Board of Directors may, at any time, authorize the issuance of a series of preferred stock that would grant to holders the preferred right to our assets upon liquidation, the right to receive dividend payments before dividends are distributed to the holders of common stock and the right to the redemption of the shares, together with a premium, before the redemption of our common stock, which may have a material adverse effect on the rights of the holders of our common stock. In addition, our Board of Directors, without further shareholder approval, may, at any time, issue large blocks of preferred stock. In addition, the ability of our Board of Directors to issue shares of preferred stock without any further action on the part of our shareholders may impede a takeover of our company and may prevent a transaction that is favorable to our shareholders.
 
Under the rules of the TASE, other than incentives under our amended 2006 stock incentive plan, we were prohibited from issuing any securities of any class or series different than the common stock that is listed on the TASE for the 12-month period immediately succeeding our initial listing, which occurred on September 6, 2010. As of the date hereof, the rules of the TASE allow us to issue securities with preferential rights with respect to dividends but such other securities may not include voting rights. The foregoing does not limit our liability to issue and grant options and warrants for the purchase of shares of our common stock.

Item 2.	Properties
 
Our manufacturing facility and executive offices are located in Carmiel, Israel. The facilities currently contain approximately 20,000 sq/ft of manufacturing space and additional 48,000 sq/ft of laboratory, warehouse and office space and are leased at a rate of approximately $86,000 per month. In addition, we are entitled to use an additional 13,000 sq/ft in the same facility, which we intend to utilize in connection with an anticipated expansion of our manufacturing facilities. Our facilities are equipped with the requisite laboratory services required to conduct our business, and we believe that the existing facilities are adequate to meet our needs for the foreseeable future. We have leased the facility through 2017, subject to three options exercisable by us to extend the term for a five-year period, for an aggregate of 15 additional years. Upon the exercise of each option to extend the term of the lease, if any, the then current base rent shall be increased by 10%. We also lease an office in Ramat Gan, Israel, for approximately $2,500 per month.

Item 7.	Management’s Discussion and Analysis of Financial Condition and Results of Operations
 
You should read the following discussion and analysis of our financial condition and results of operations together with our consolidated financial statements and the related notes included elsewhere in this Annual Report on Form 10-K. Some of the information contained in this discussion and analysis, particularly with respect to our plans and strategy for our business and related financing, includes forward-looking statements that involve risks and uncertainties. You should read “Risk Factors” in Item 1A of this Annual Report on Form 10-K for a discussion of important factors that could cause actual results to differ materially from the results described in or implied by the forward-looking statements contained in the following discussion and analysis.
 
Overview
 
We are a biopharmaceutical company focused on the development and commercialization of recombinant therapeutic proteins based on our proprietary ProCellEx protein expression system. Using our ProCellEx system, we are developing a pipeline of proprietary, biobetter and biosimilar versions of recombinant therapeutic proteins, based on our plant cell-based expression technology, that primarily target large, established pharmaceutical markets and that rely upon known biological mechanisms of action. Our initial commercial focus has been on complex therapeutic proteins, including proteins for the treatment of genetic disorders, such as Gaucher disease and Fabry disease. We believe ProCellEx will enable us to develop proprietary recombinant proteins that are therapeutically equivalent or superior to existing recombinant proteins currently marketed for the same indications. Because we are primarily targeting biologically equivalent versions of highly active, well-tolerated and commercially successful therapeutic proteins, we believe our development process is associated with relatively less risk compared to other biopharmaceutical development processes for completely novel therapeutic proteins. We are now also applying the unique properties of our ProCellEx system for the oral delivery of therapeutic proteins, with the first two product candidates being glucocerebrosidase and antiTNF fusion protein.
 
On May 1, 2012, the FDA approved for sale our first commercial product, taliglucerase alfa for injection, which is being marketed in the United States and Israel under the brand name ELELYSO, as an enzyme replacement therapy, or ERT, for the long-term treatment of adult patients with a confirmed diagnosis of type 1 Gaucher disease. Subsequently, taliglucerase alfa was approved by ANVISA in March 2013, by the Israeli MOH in September 2012, and by the applicable regulatory authorities in Uruguay, Mexico and Chile. Taliglucerase alfa will be marketed under the name UPLYSO in Brazil and certain other Latin American countries. Taliglucerase alfa is our proprietary, recombinant form of glucocerebrosidase, or GCD, that is produced or expressed through ProCellEx. Taliglucerase alfa is the first plant cell-based recombinant therapeutic protein to be approved by the FDA or by the regulatory authorities with jurisdiction over any substantial market. Gaucher disease is a rare and serious lysosomal storage disorder with severe and debilitating symptoms. Gaucher patients suffer from mutations in or deficiencies of GCD, an enzyme that is naturally found in human cells.
 
Since May 2012, taliglucerase alfa has been marketed in the United States by Pfizer, our commercialization partner, as provided in the Pfizer Agreement. We granted Pfizer an exclusive, worldwide license to develop and commercialize taliglucerase alfa under the Pfizer Agreement, but we retained those rights in Israel and in Brazil. We have agreed to a specific allocation between Protalix Ltd. and Pfizer of the responsibilities for the continued development efforts for taliglucerase alfa outside of Israel. Since 2013, taliglucerase alfa has been marketed in Israel by Protalix Ltd.
 
On June 18, 2013, we entered into the Brazil Agreement with Fiocruz for taliglucerase alfa. The agreement became effective in January 2014. The technology transfer is designed to be completed in four stages and is intended to transfer to Fiocruz the capacity and skills required for the Brazilian government to construct its own manufacturing facility, at its sole expense, and to produce a sustainable, high-quality, and cost-effective supply of taliglucerase alfa. The initial term of the technology transfer is seven years. Under the agreement, Fiocruz has committed to purchase at least approximately $40 million worth of taliglucerase alfa during the first two years of the term. In subsequent years, Fiocruz is required to purchase at least approximately $40 million worth of taliglucerase alfa per year. Additionally, we are not required to complete the final stage of the technology transfer until Fiocruz purchases at least approximately $280 million worth of taliglucerase alfa.
 
We are cooperating with Pfizer to obtain marketing approval for taliglucerase alfa in additional countries and jurisdictions. In addition to those countries in which taliglucerase alfa has been approved, marketing authorization applications have been filed in other countries.
 
In December 2012, we entered into a Clinical Development Agreement with Pfizer under which we will continue to manage, administer and sponsor current, ongoing clinical trials relating to ELELYSO. We are currently sponsoring extension studies of ELELYSO in adult and pediatric patients. New clinical trials for ELELYSO, if it is elected that any such clinical trial be performed, will be conducted and sponsored by Pfizer. Under the terms of the agreement, we were eligible to receive a payment of $8.3 million upon the achievement of certain near-term clinical development goals. The goals were achieved prior to the end of fiscal year 2012 and the $8.3 million payment has been paid in full. This agreement helps to maintain the continuity of the ongoing clinical trials for Gaucher patients and physicians and reinforces the companies’ mutual commitment to the Gaucher community.

We performed a number of studies on taliglucerase alfa to supplement the pivotal phase III clinical trial, which we completed in September 2009. We initiated a double-blind, follow-on extension study in 2008 which consisted of eligible patients who had completed nine months of treatment in the pivotal phase III clinical trial. The patients were offered the opportunity to continue to receive taliglucerase alfa at the same dose they received in the pivotal trial for an additional 15 months in a blinded manner. We also conducted a nine-month, worldwide, multi-center, open-label, switch-over clinical study evaluating the safety and efficacy of switching Gaucher patients currently treated with Cerezyme, which is produced by Genzyme, with taliglucerase alfa, which was successfully completed in 2011. We also conducted a 12-month clinical trial of naïve and switchover pediatric patients, which was successfully completed in 2012. Based on the data from this study, an application for a supplement to the NDA for ELEYSO, allowing a pediatric use indication to be added to the product label, has recently been submitted by Pfizer to the FDA. Patients in the extension trials are still being treated with taliglucerase alfa.
 
Currently, patients are being treated with taliglucerase alfa on a commercial basis in the United States, Brazil, Israel and Chile. Globally, patients are being treated through our extension trials and related studies, compassionate use programs, special access agreements, named patient provisions and other programs designed to ensure that treatments are available to Gaucher patients in light of recent shortages of approved treatments. In France, Gaucher patients are being treated with taliglucerase alfa through an Autorisation Temporaire d’Utilisation (ATU), or Temporary Authorization for Use, a regulatory mechanism used by the French Health Products and Safety Agency to make non-approved drugs available to patients in France when a genuine public health need exists. In addition to the United States and France, taliglucerase alfa is currently being provided to Gaucher patients under special access agreements or named patient provisions in Brazil and in other countries. Hundreds of patients, in the aggregate, have been treated with taliglucerase alfa.
 
In addition to taliglucerase alfa, we are developing an innovative product pipeline using our ProCellEx protein expression system. Our product pipeline currently includes, among other candidates: PRX-102, a therapeutic protein candidate for the treatment of Fabry disease; PRX-112, an orally administered glucocerebrosidase enzyme for the treatment of Gaucher patients utilizing oral delivery of the recombinant GCD enzyme produced and encapsulated within carrot cells; PRX-106, an oral antiTNF, a plant cell expressed recombinant fusion protein combined of the binding domain of the human TNF receptor (TNFR) and an antibody portion, which is being developed for the treatment of certain immune and inflammatory diseases, such as rheumatoid arthritis, colitis, Crohn’s disease, psoriasis and other autoimmune and inflammatory disorders; PRX-110, a proprietary plant cell recombinant human Deoxyribonuclease 1 under development for the treatment of cystic fibrosis, to be administered by inhalation; PRX-107, a proprietary plant cell recombinant AAT; and others.
 
Except for the rights to commercialize taliglucerase alfa worldwide (other than Brazil and Israel), which we licensed to Pfizer, we hold the worldwide commercialization rights to all of our proprietary development candidates. We have built an internal marketing team designed to serve the Israeli market for taliglucerase alfa and we intend to establish internal commercialization and marketing teams for our other product candidates in North America, the European Union and in other significant markets, including Israel, subject to required marketing approvals, as the need arises. In addition, we continuously evaluate potential strategic marketing partnerships as well as collaboration programs with biotechnology and pharmaceutical companies and academic research institutes.
 
Critical Accounting Policies
 
Our significant accounting policies are more fully described in Note 1 to our consolidated financial statements appearing at the end of this Annual Report on Form 10-K. We believe that the accounting policies below are critical for one to fully understand and evaluate our financial condition and results of operations.
 
The discussion and analysis of our financial condition and results of operations is based on our financial statements, which we prepared in accordance with U.S. generally accepted accounting principles. The preparation of these financial statements requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements, as well as the reported revenues and expenses during the reporting periods. On an ongoing basis, we evaluate such estimates and judgments, including those described in greater detail below. We base our estimates on historical experience and on various other factors that we believe are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.
 
57	

 	
  
Functional Currency
 
The currency of the primary economic environment in which our operations are conducted is the U.S. dollar. Most of our revenues are derived in dollars. In addition, most of our expenses and capital expenditures are incurred in dollars, and the major source of our financing has been provided in dollars.
 
Revenues
 
Currently, our source of revenues comes from sales of taliglucerase alfa pursuant to our license agreement with Pfizer, our sales of taliglucerase alfa in Israel and Brazil and from milestone payments under the Pfizer Agreement. We recognize revenue when the earnings process is complete, which is when revenue is realized or realizable and earned, there is persuasive evidence a revenue arrangement exists, delivery of goods or services has occurred, the sales price is fixed or determinable and collectability is reasonably assured.
 
We recognize revenue from milestone payments received pursuant to the Pfizer Agreement in accordance with guidance regarding revenue recognition and accounting for revenue arrangements with multiple deliverables. Pursuant to this guidance, we determine whether our arrangement with Pfizer involves multiple revenue-generating deliverables that should be accounted for as a combined unit of accounting or separate units of accounting for revenue recognition purposes. If we determine that there are multiple units of accounting, the consideration from the arrangement is allocated among the separate units based on a relative fair value allocation. If the arrangement represents a single unit of accounting, the revenue is recognized over the performance obligation period. As the arrangement with Pfizer requires our continued involvement with respect to the proposed commercialization of taliglucerase alfa, the non-refundable, up-front license payments we received from Pfizer are deferred and recognized over the related performance period. We estimated the performance period of 14 years based on the date that the last relevant patent relating to taliglucerase alfa expires. The $25.0 million milestone payment received in connection with the FDA’s approval of taliglucerase alfa in the United States was considered to be a substantive milestone for purposes of revenue recognition, and, accordingly, was recorded as revenue during the period in which the milestone was achieved.
 
Under the terms and conditions of the Pfizer Agreement, we are entitled to 40% of the net profits or loss from sales of taliglucerase alfa by Pfizer and reimbursement of our certain related expenses we incur in connection with Pfizer’s sales (other than those related to sales in Israel). We hold all rights to taliglucerase alfa in Israel and Brazil. We recognize our share of net profit or loss under the Pfizer Agreement based on reports we receive from Pfizer summarizing the results of the collaborative activities under the agreement for the applicable period. Under the terms of the Pfizer Agreement, for its subsidiaries operating outside the United States, financial information is included based on the fiscal year ending November 30, while financial information for the U.S. entity is included based on the fiscal year ending December 31.
 
We recognize revenues received from the sale of a product when the sales price is fixed or determinable and collectability is reasonably assured. The revenues represent our cost with respect to the product sold.
 
We recognize net product revenue from our sales of ELELYSO in Israel when persuasive evidence of an arrangement exists, the product has been delivered to the customer, title and risk of loss have passed to the customer, the price to the buyer is fixed or determinable and collection from the customer is reasonably assured. Product sale transactions are evidenced by customer purchase orders, customer contracts, invoices and/or the related shipping documents. Amounts collected from customers and remitted to governmental authorities, which represents value-added taxes related to ELELYSO sales in Israel, are presented on a net basis in our Consolidated Statements of Operations, in that taxes billed to customers are not included as a component of net product revenues.
 
Research and Development Expense
 
We expect our research and development expense to remain our primary expense in the near future as we continue to develop our product candidates. Research and development expense consists of:
 
 	·	internal costs associated with research and development activities; 	
 	·	payments made to third party contract research organizations, investigative/clinical sites and consultants; 	
 	·	manufacturing development costs; 	
 	·	personnel-related expenses, including salaries, benefits, travel, and related costs for the personnel involved in research and development; 	
 	·	activities relating to the advancement of product candidates through preclinical studies and clinical trials; and	
 	·	facilities and other allocated expenses, which include direct and allocated expenses for rent and maintenance of facilities, as well as laboratory and other supplies.	
 
58	

 	
  
The following table identifies our current major research and development projects:
 
Project	 	Status	 	Expected Near Term Milestones	
PRX 102 - alpha-GAL-A	 	Phase I/II clinical trial, ongoing	 	Report interim results	
 	 	 	 	 	
Oral Glucocerebrosidase	 	Phase I clinical trial completed 	 	Initiate next phase clinical trial	
 	 	 	 	 	
Oral antiTNF	 	Research	 	Initiate phase I clinical trial	
 	 	 	 	 	
DNase I	 	Preclinical	 	File IND 	
 
We anticipate incurring increasing costs in connection with our PRX-102 and oral glucocerebrosidase projects which will be partially off set by the decrease in costs incurred due to the continued winding down of our taliglucerase alfa clinical trials during 2014. Our other projects are in the early clinical, preclinical or research phases with relatively immaterial costs. To date, most of our research and development costs were incurred in connection with our phase III clinical trial of taliglucerase alfa. Our internal resources, employees and infrastructure are not tied to any individual research project and are typically deployed across all of our projects. We currently do not record and maintain research and development costs per project.
 
The costs and expenses of our projects are partially funded by grants we have received from the OCS. Each grant is deducted from the related research and development expenses as the costs are incurred. For additional information regarding the grant process, see “Business-Israeli Government Programs-Encouragement of Industrial Research and Development Law, 1984” in Item 1 of this Annual Report. There can be no assurance that we will continue to receive grants from the OCS in amounts sufficient for our operations, if at all.
 
At this time, due to the inherently unpredictable nature of preclinical and clinical development processes and given the early stage of our preclinical product development programs, we are unable to estimate with any certainty the costs we will incur in the continued development of the product candidates in our pipeline for potential commercialization. Clinical development timelines, the probability of success and development costs can differ materially from expectations. While we are currently focused on advancing each of our product development programs, our future research and development expenses will depend on the clinical success of each product candidate, as well as ongoing assessments of each product candidate’s commercial potential. In addition, we cannot forecast with any degree of certainty which product candidates may be subject to future collaborations, when such arrangements will be secured, if at all, and to what degree such arrangements would affect our development plans and capital requirements. See “Risk Factors-If we are unable to develop and commercialize our product candidates, our business will be adversely affected” and “-We may not obtain the necessary U.S., EMA or other worldwide regulatory approvals to commercialize our drug candidates in a timely manner, if at all, which would have a material adverse effect on our business, financial condition and results of operations.”
 
We expect our research and development expenses to continue to be our primary expense in the future as we continue the advancement of our clinical trials and preclinical product development programs for our product candidates other than taliglucerase alfa. The lengthy process of completing clinical trials and seeking regulatory approval for our product candidates requires expenditure of substantial resources. Any failure or delay in completing clinical trials, or in obtaining regulatory approvals, could cause a delay in generating product revenue and cause our research and development expense to increase and, in turn, have a material adverse effect on our operations. Due to the factors set forth above, we are not able to estimate with any certainty when we would recognize any net cash inflows from our projects. See “Risk Factors-Clinical trials are very expensive, time-consuming and difficult to design and implement and may result in unforeseen costs which may have a material adverse effect on our business, results of operations and financial condition.”
 
Share-Based Compensation
 
The discussion below regarding share-based compensation relates to share-based compensation paid by Protalix Ltd., our wholly-owned subsidiary.
 
In accordance with the guidance, we record the benefit of any grant to a non-employee and remeasure the benefit in any future vesting period for the unvested portion of the grants, as applicable. In addition, we use the straight-line accounting method for recording the benefit of the entire grant, unlike the graded method we use to record grants made to employees.
 
59	

 	
 
We measure share-based compensation cost for all share-based awards at the fair value on the grant date and recognition of share-based compensation over the service period for awards that we expect will vest. The fair value of stock options is determined based on the number of shares granted and the price of our ordinary shares, and calculated based on the Black-Scholes valuation model. We recognize such value as expense over the service period, net of estimated forfeitures, using the accelerated method.
 
For purposes of determining the fair value of the restricted shares of common stock granted to employees during the fiscal year ended December 31, 2013, our management used the fair value of our common stock which was the closing sale price of our common stock on the NYSE MKT on the date of grant.
 
The guidance requires companies to estimate the expected term of the option rather than simply using the contractual term of an option. Because of lack of data on past option exercises by employees, the expected term of the options could not be based on historic exercise patterns. Accordingly, we adopted the simplified method, according to which companies may calculate the expected term as the average between the vesting date and the expiration date, assuming the option was granted as a “plain vanilla” option.
 
In performing the valuation, we assumed an expected 0% dividend yield in the previous years and in the next years. We do not have a dividend policy and given the lack of profitability, dividends are not expected in the foreseeable future, if at all. The guidance stipulates a number of factors that should be considered when estimating the expected volatility, including the implied volatility of traded options, historical volatility and the period that the shares of the company are being publicly traded.
 
The risk-free interest rate described above has been based on the implied yield of U.S. federal reserve zero-coupon government bonds. The remaining term of the bonds used for each valuation was equal to the expected term of the grant. This methodology has been applied to all grants valued by us. The guidance requires the use of a risk-free interest rate based on the implied yield currently available on zero-coupon government issues of the country in whose currency the exercise price is expressed, with a remaining term equal to the expected life of the option being valued. This requirement has been applied for all grants valued as part of this report.
 
Year Ended December 31, 2013 Compared to the Year Ended December 31, 2012
 
Revenues
 
We recorded revenue of $10.5 million for the year ended December 31, 2013, an increase of approximately $609,000, or 6%, compared to revenue of $9.9 million for the year ended December 31, 2012, excluding the one time $25.0 million payment we received from Pfizer under the Pfizer Agreement in connection with the FDA’s approval of taliglucerase alfa on May 1, 2012. The revenues represent our sales of taliglucerase alfa in Israel, the cost of products we deliver to Pfizer under the Pfizer Agreement and a pro rata amortization equal to $1.1 million in each quarterly period resulting from the $65.0 million upfront and milestone payments we received from Pfizer in 2009. The revenues for the year ended December 31, 2013 include $5.0 million from products we sold in Israel.
 
Our share in the Collaboration Agreement
 
We recorded revenue of $1.0 million as our share of net income in the collaboration under the Pfizer Agreement during the year ended December 31, 2013, compared to the $446,000 of loss recorded for the year ended December 31, 2012. Our share in the collaboration recorded for the year ended December 31, 2013 represents our 40% share of the net income generated during the period, which was primarily the result of revenues generated by Pfizer in the United States which exceeded the expenses during such period. Under the terms and conditions of the Pfizer Agreement, we record income or loss equal to 40% of the profit or loss realized from sales of taliglucerase alfa and related expenses incurred based on reports we receive from Pfizer summarizing the results of the collaborative activities under the Pfizer Agreement for the applicable period. Under the terms and conditions of the Pfizer Agreement, financial information of Pfizer’s subsidiaries that operate outside the United States is included based on the fiscal year ending November 30, while financial information for the U.S. entity is included based on the fiscal year ending December 31.
 
60	

 	
  
Cost of Revenues
 
Cost of revenues was $5.4 million for the year ended December 31, 2013, a decrease of $2.7 million, or 33%, compared to the cost of revenues of $8.1 million for the year ended December 31, 2012. Cost of revenues for the year ended December 31, 2013 consists primarily of certain fixed costs relating to our manufacturing facility, including rent, depreciation, salary and maintenance expenses amounting to approximately $4.9 million, and to a much lesser extent, the direct cost of products we sold in Israel and products we delivered to Pfizer for which revenues were recognized during the period. Cost of revenues for the years ended December 31, 2012 and 2013 include an aggregate of $2.2 million and $472,000, respectively, in royalties payable to the OCS and to a certain academic institution in connection with gross sales of taliglucerase alfa during the period. Prior to the FDA’s approval of taliglucerase alfa, manufacturing costs related to taliglucerase alfa were classified as research and development expenses. Effective as of the FDA approval of taliglucerase alfa, we capitalize all manufacturing costs associated with taliglucerase alfa and expense such costs as cost of revenues, as applicable.
 
Research and Development Expenses
 
Research and development expenses were $33.3 million for the year ended December 31, 2013, a decrease of $3.4 million, or 9.1% from $36.7 million for the year ended December 31, 2012. The decrease resulted primarily from a decrease of $2.1 million in payroll and related expenses primarily due to a decrease in share-based compensation and a decrease of $1.2 million resulting from the winding down of certain clinical trials for taliglucerase alfa.
 
We expect research and development expenses to continue to be our primary expense as we enter into a more advanced stage of preclinical and clinical trials for certain of our product candidates.
 
General and Administrative Expenses
 
General and administrative expenses were $8.4 million for the year ended December 31, 2013, a decrease of $1.4 million, or 14%, from $9.8 million for the year ended December 31, 2012. The decrease resulted primarily from a decrease of $1.5 million in payroll and related expenses primarily due to a decrease in share-based compensation.
 
Financial Expenses and Income
 
Financial expense was $674,000 for the year ended December 31, 2013, compared to financial income of $554,000 for the year ended December 31, 2012. Financial expense resulted primarily from interest expense of $1.0 million for the 4.5% convertible note which was partially offset by financial income which resulted primarily from interest earned on short term deposits.
 
Year Ended December 31, 2012 Compared to the Year Ended December 31, 2011
 
Revenues
 
We recorded revenue of $34.9 million for the year ended December 31, 2012, an increase of $26.5 million or 315%, compared to revenue of $8.4 million for the year ended December 31, 2011. The increase resulted primarily from the $25.0 million milestone payment we received from Pfizer in connection with the FDA’s approval of taliglucerase alfa in the United States. The increase was also due to the increase in the supply of taliglucerase alfa vials to Pfizer during the year ended December 31, 2012. Revenues also include the amortization of the $65.0 million upfront and milestone payments received from Pfizer. The payments were recorded as deferred revenue and the amounts will be amortized over the performance period, estimated at approximately 14 years, at a rate of approximately $1.1 million per quarter.
 
Our share in the Collaboration Agreement
 
We recorded a loss of $446,000 as our share in the collaboration under the Pfizer Agreement during the year ended December 31, 2012, a decrease of $5.0 million, or 92%, compared to the $5.4 million of loss recorded for the year ended December 31, 2011. Our share in the collaboration’s loss for the year ended December 31, 2012 represents our 40% share of the net loss generated during the period, which was primarily the result of the expenses incurred during the period mainly in connection with activities related to the U.S. launch of taliglucerase alfa which exceeded the revenues generated by Pfizer in the United States, and resupply in Brazil. Under the terms and conditions of the Pfizer Agreement, we record income or loss equal to 40% of the profit or loss realized from sales of taliglucerase alfa and related expenses incurred based on reports we receive from Pfizer summarizing the results of the collaborative activities under the Pfizer Agreement for the applicable period. Under the terms and conditions of the Pfizer Agreement, financial information of Pfizer’s subsidiaries that operate outside the United States is included based on the fiscal year ending November 30, while financial information for the U.S. entity is included based on the fiscal year ending December 31.

Cost of Revenues
 
Cost of revenues was $8.1 million for the year ended December 31, 2012, an increase of $6.6 million, compared to the cost of revenues of $1.5 million for the year ended December 31, 2011. Cost of revenues for the year ended December 31, 2012 includes approximately $2.2 million for royalties due to the OCS and a certain academic institution in connection with gross sales of taliglucerase alfa during the period and $4.1 million for certain fixed costs relating mainly to our manufacturing facility, including rent, depreciation, salary and maintenance expenses, and to a much lesser extent, the direct cost of products delivered to Pfizer during the period. Prior to the FDA’s approval of taliglucerase alfa, manufacturing costs related to taliglucerase alfa were not capitalized; rather, such costs were expensed as research and development expenses. Effective as of the FDA approval of taliglucerase alfa on May 1, 2012, we capitalize all manufacturing costs associated with taliglucerase alfa.
 
Research and Development Expenses
 
Research and development expenses were $36.7 million for the year ended December 31, 2012, a decrease of $1.1 million from $37.8 million for the year ended December 31, 2011. The decrease resulted primarily from a decrease of $2.6 million in expenses related to consulting and subcontractors, and a decrease of $2.8 million in certain expenses, such as rent, depreciation and maintenance, that were classified as cost of revenues or capitalized as inventory after the FDA’s approval of taliglucerase alfa on May 1, 2012. Such decrease was partially offset by an increase of $4.9 million in salaries expense associated with research and development activities mainly due to share-based compensation, bonuses paid in connection with the FDA’s approval of taliglucerase alfa and the initiation of the phase I/II clinical trial of PRX-102 for Fabry disease.
 
We expect research and development expenses to continue to be our primary expense as we enter into a more advanced stage of preclinical and clinical trials for certain of our product candidates.
 
General and Administrative Expenses
 
General and administrative expenses were $9.8 million for the year ended December 31, 2012, an increase of $2.8 million, or 41%, from $6.9 million for the year ended December 31, 2011. The increase resulted primarily from an increase of $3.3 million in salaries expense primarily due to bonuses paid in connection with the FDA’s approval of taliglucerase alfa on May 1, 2012 and share-based compensation. The increase was partially offset by a decrease of $646,000 in legal and accounting expenses.
 
Financial Expenses and Income
 
Financial income was $554,000 for the year ended December 31, 2012, an increase of $552,000 from $2,000 for the year ended December 31, 2011. The increase resulted primarily from the higher average cash balance during the year 2012 compared to 2011 which earned interest.
 
Liquidity and Capital Resources
 
Sources of Liquidity
 
As a result of our significant research and development expenditures and the lack of significant product sales revenue due to the recent launch of taliglucerase alfa in the United States and Israel, we have not been profitable and have generated operating losses since our inception. To date, we have funded our operations primarily with proceeds equal to $31.3 million from the sale of shares of convertible preferred and ordinary shares of Protalix Ltd., and an additional $14.1 million in connection with the exercise of warrants issued in connection with the sale of such shares, through December 31, 2008. In addition, on October 25, 2007, we generated gross proceeds of $50 million in connection with an underwritten public offering of our common stock and on each of March 23, 2011 and February 22, 2012, we generated gross proceeds of $22.0 million and $27.2 million, respectively, in connection with underwritten public offerings of our common stock. We believe that the funds currently available to us as are sufficient to satisfy our capital needs for at least 12 months.
 
The following table summarizes our public funding sources since 2007:
 
Security	 	Year	 	 	Number of Shares	 	 	Amount	 	
Common Stock	 	 	2007	 	 	 	10,000,000	 	 	$	50,000,000	 	
Common Stock	 	 	2011	 	 	 	4,000,000	 	 	$	22,000,000	 	
Common Stock	 	 	2012	 	 	 	5,175,000	 	 	$	27,168,750	 	
 
In addition to the foregoing, on September 18, 2013, we completed a private placement of $69.0 million in aggregate principal amount of 4.50% convertible notes due 2018, or the Notes, including $9.0 million aggregate principal amount of Notes related to the offering’s initial purchaser’s over-allotment option, which was exercised in full.

Pfizer paid Protalix Ltd. $60.0 million as an upfront payment in connection with the execution of the Pfizer Agreement and subsequently paid to Protalix Ltd. an additional $5.0 million upon Protalix Ltd.’s meeting a certain milestone. Protalix Ltd. also received a milestone payment of $25.0 in connection with the FDA’s approval of taliglucerase alfa in May 2012. Protalix Ltd. is also entitled to payments equal to 40% of the net profits earned by Pfizer on its global sales of taliglucerase alfa (except in Israel). In calculating net profits there are certain agreed upon limits on the amounts that may be deducted from gross sales for certain expenses and costs of goods sold. Pfizer has also paid Protalix Ltd. $8.3 million in connection with the successful achievement of certain milestones under the Clinical Development Agreement between Pfizer and Protalix Ltd.
 
Cash Flows
 
Net cash used in operations was $30.7 million for the year ended December 31, 2013. The net loss for the year ended December 31, 2013 of $27.8 million was further increased by a decrease of $7.2 million in deferred revenues and an increase of $3.9 million in inventories, but was partially offset by share based compensation of $4.1 million and $3.5 million in depreciation. Net cash used in investing activities for the year ended December 31, 2013 was $2.1 million and consisted primarily of purchases of property and equipment. Net cash provided by financing activities was $66.9 million, consisting primarily of net proceeds from our offering of 2018 4.5% convertible notes.
 
Net cash provided by operations was $635,000 for the year ended December 31, 2012. The net loss for the year ended December 31, 2012 of $11.6 million decreased primarily due to $7.8 million in share-based compensation and $3.7 million in depreciation and a $3.0 million increase in accounts payable, which was partially offset by a an increase of $3.8 million in inventory. Net cash used in investing activities for the year ended December 31, 2012 was $2.3 million and consisted primarily of purchases of property and equipment. Net cash provided by financing activities was $26.6 million, consisting primarily of net proceeds from our February 2012 underwritten public offering of common stock.
 
Future Funding Requirements
 
We expect to continue to incur significant expenditures in the near future. However, we anticipate that we will generate revenues to offset such losses as Pfizer’s commercialization efforts for taliglucerase alfa in the United States and as our commercialization efforts for taliglucerase alfa in Brazil and Israel progress, and as taliglucerase alfa is launched by Pfizer in other countries in which taliglucerase alfa was recently approved. We also anticipate that we will generate additional revenues after additional anticipated marketing approvals of taliglucerase alfa are granted in new countries. We expect to continue to incur significant research and development expenses, including expenses related primarily to the clinical trials of PRX-102 and oral glucocerebrosidase and the advancement of our other product candidates into clinical trials.
 
We believe that our existing cash and cash equivalents will be sufficient to enable us to fund our operating expenses and capital expenditure requirements for the foreseeable future. We have based this estimate on assumptions that are subject to change and may prove to be wrong, and we may be required to use our available capital resources sooner than we currently expect. Because of the numerous risks and uncertainties associated with the development and commercialization of our product candidates, we are unable to estimate the amounts of increased capital outlays and operating expenditures associated with our current and anticipated clinical trials.
 
Our future capital requirements will depend on many factors, including the progress of Pfizer’s commercialization efforts for taliglucerase alfa in the United States and other countries, the progress of our commercialization efforts for taliglucerase alfa in Brazil and Israel and, if anticipated marketing approvals of taliglucerase alfa are granted in other jurisdictions, the progress of Pfizer’s global commercialization efforts for taliglucerase alfa, the progress and results of our clinical trials, the duration and cost of discovery and preclinical development and laboratory testing and clinical trials for our product candidates, the timing and outcome of regulatory review of our product candidates, the costs involved in preparing, filing, prosecuting, maintaining, defending and enforcing patent claims and other intellectual property rights, the number and development requirements of other product candidates that we pursue and the costs of commercialization activities, including product marketing, sales and distribution.
 
We may need to finance our future cash needs through public or private equity offerings, debt financings, or corporate collaboration and licensing arrangements. We currently do not have any commitments for future external funding. We may need to raise additional funds more quickly if one or more of our assumptions prove to be incorrect or if we choose to expand our product development efforts more rapidly than we presently anticipate. We may also decide to raise additional funds even before we need them if the conditions for raising capital are favorable. Any sale of additional equity or debt securities will likely result in dilution to our shareholders. The incurrence of indebtedness would result in increased fixed obligations and could also result in covenants that would restrict our operations. Additional equity or debt financing, grants or corporate collaboration and licensing arrangements may not be available on acceptable terms, if at all. If adequate funds are not available, we may be required to delay, reduce the scope of or eliminate our research and development programs, reduce our planned commercialization efforts or obtain funds through arrangements with collaborators or others that may require us to relinquish rights to certain product candidates that we might otherwise seek to develop or commercialize independently.

Effects of Inflation and Currency Fluctuations
 
Inflation generally affects us by increasing our cost of labor and clinical trial costs. We do not believe that inflation has had a material effect on our results of operations during the years ended December 31, 2011, 2012 or 2013.
 
Currency fluctuations could affect us by increased or decreased costs mainly for goods and services acquired outside of Israel. We do not believe currency fluctuations have had a material effect on our results of operations during the years ended December 31, 2011, 2012 or 2013.
 
Off-Balance Sheet Arrangements
 
We have no off-balance sheet arrangements as of December 31, 2012 and 2013.
 
Recently Issued Accounting Pronouncements
 
None.

The foregoing table does not include (i) annual license fees, which are immaterial, (ii) payments we may be required to make to certain of our licensors in the time periods set forth above upon the achievement of agreed-upon milestones and (iii) royalty payments payable by us to certain of our licensors in connection with the commercial sale of our product candidates, if any. If all of the contingencies with respect to milestone payments under our research and license agreements are met, the aggregate milestone payments payable would be approximately $0.3 million and would be payable, if at all, as our projects progress over the course of a number of years. The royalty payments payable in connection with sales of each of our product candidates, if at all, shall not exceed low, single-digit percentages of net sales of the product.

Item 7A.          Quantitative and Qualitative Disclosures about Market Risk
 
Currency Exchange Risk
 
The currency of the primary economic environment in which our operations are conducted is the dollar. We are currently have no significant source of revenues; therefore we consider the currency of the primary economic environment to be the currency in which we expend cash. Approximately 50% of our expenses and capital expenditures are incurred in dollars, and a significant source of our financing has been provided in U.S. dollars. Since the dollar is the functional currency, monetary items maintained in currencies other than the dollar are remeasured using the rate of exchange in effect at the balance sheet dates and non-monetary items are remeasured at historical exchange rates. Revenue and expense items are remeasured at the average rate of exchange in effect during the period in which they occur. Foreign currency translation gains or losses are recognized in the statement of operations.
 
Approximately 35% of our costs, including salaries, expenses and office expenses, are incurred in NIS. Inflation in Israel may have the effect of increasing the U.S. dollar cost of our operations in Israel. If the U.S. dollar declines in value in relation to the NIS, it will become more expensive for us to fund our operations in Israel. A revaluation of 1% of the NIS will affect our income before tax by less than 1%. The exchange rate of the U.S. dollar to the NIS, based on exchange rates published by the Bank of Israel, was as follows:
 
 	 	Year Ended December 31,	 	
 	 	2011	 	 	2012	 	 	2013	 	
Average rate for period	 	 	3.578	 	 	 	3.856	 	 	 	3.611	 	
Rate at year-end	 	 	3.821	 	 	 	3.733	 	 	 	3.471	 	
  
To date, we have not engaged in hedging transactions. In the future, we may enter into currency hedging transactions to decrease the risk of financial exposure from fluctuations in the exchange rate of the U.S. dollar against the NIS. These measures, however, may not adequately protect us from material adverse effects due to the impact of inflation in Israel.
 
Interest Rate Risk
 
Our exposure to market risk is confined to our cash and cash equivalents. We consider all short term, highly liquid investments, which include short-term deposits with original maturities of three months or less from the date of purchase, that are not restricted as to withdrawal or use and are readily convertible to known amounts of cash, to be cash equivalents. The primary objective of our investment activities is to preserve principal while maximizing the interest income we receive from our investments, without increasing risk. We invest any cash balances primarily in bank deposits and investment grade interest-bearing instruments. We are exposed to market risks resulting from changes in interest rates. We do not use derivative financial instruments to limit exposure to interest rate risk. Our interest gains may decline in the future as a result of changes in the financial markets.

Item 9A.	 Controls and Procedures
 
Evaluation of Disclosure Controls and Procedures
 
We conducted an evaluation of the effectiveness of the design and operation of our disclosure controls and procedures as of the end of the period covered by this Form 10-K. The controls evaluation was conducted under the supervision and with the participation of management, including our Chief Executive Officer and Chief Financial Officer. Disclosure controls and procedures are controls and procedures designed to reasonably assure that information required to be disclosed in our reports filed under the Exchange Act, such as this Form 10-K, is recorded, processed, summarized and reported within the time periods specified in the Commission’s rules and forms. Disclosure controls and procedures are also designed to reasonably assure that such information is accumulated and communicated to our management, including the Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure.
 
65	

 	
  
The evaluation of our disclosure controls and procedures included a review of the controls’ objectives and design, our implementation of the controls and their effect on the information generated for use in this Form 10-K. In the course of the controls evaluation, we reviewed identified data errors, control problems or acts of fraud, and sought to confirm that appropriate corrective actions, including process improvements, were being undertaken. This type of evaluation will be performed on a quarterly basis so that the conclusions of management, including the Chief Executive Officer and Chief Financial Officer, concerning the effectiveness of the disclosure controls and procedures can be reported in our periodic reports on Form 10-Q and Form 10-K. The overall goals of these various evaluation activities are to monitor our disclosure controls and procedures, and to modify them as necessary. Our intent is to maintain the disclosure controls and procedures as dynamic systems that change as conditions warrant.
 
Based on the controls evaluation, our Chief Executive Officer and Chief Financial Officer have concluded that, as of the end of the period covered by this Form 10-K, our disclosure controls and procedures were effective to provide reasonable assurance that information required to be disclosed in our Exchange Act reports is recorded, processed, summarized and reported within the time periods specified by the Commission, and that material information related to our company and our consolidated subsidiary is made known to management, including the Chief Executive Officer and Chief Financial Officer, particularly during the period when our periodic reports are being prepared.
 
Management Report on Internal Control over Financial Reporting
 
Our management is responsible for establishing and maintaining adequate internal control over financial reporting to provide reasonable assurance regarding the reliability of our financial reporting and the preparation of financial statements for external purposes in accordance with U.S. generally accepted accounting principles. Internal control over financial reporting includes those policies and procedures that: (i) pertain to the maintenance of records that in reasonable detail accurately and fairly reflect the transactions and dispositions of our assets; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with U.S. generally accepted accounting principles, and that receipts and expenditures of our company are being made only in accordance with authorizations of management and our directors; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of our assets that could have a material effect on our financial statements.
 
Management assessed our internal control over financial reporting as of December 31, 2013, the end of our fiscal year. Management based its assessment on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (1992). Management’s assessment included evaluation of elements such as the design and operating effectiveness of key financial reporting controls, process documentation, accounting policies and our overall control environment.
 
Based on our assessment, management has concluded that our internal control over financial reporting was effective as of the end of the fiscal year to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external reporting purposes in accordance with U.S. generally accepted accounting principles. We reviewed the results of management’s assessment with the Audit Committee of our Board of Directors.
 
The effectiveness of our internal control over financial reporting as of December 31, 2013 has been audited by Kesselman & Kesselman, an independent registered public accounting firm, as stated in their report included herein.
 
Inherent Limitations on Effectiveness of Controls
 
Our management, including our Chief Executive Officer and Chief Financial Officer, does not expect that our disclosure controls and procedures or our internal control over financial reporting will prevent or detect all error and all fraud. A control system, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that the control system’s objectives will be met. The design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Further, because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that misstatements due to error or fraud will not occur or that all control issues and instances of fraud, if any, within a company have been detected. These inherent limitations include the realities that judgments in decision-making can be faulty and that breakdowns can occur because of simple error or mistake. Controls can also be circumvented by the individual acts of some persons, by collusion of two or more people or by management override of the controls. The design of any system of controls is based in part on certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions. Projections of any evaluation of controls effectiveness to future periods are subject to risks. Over time, controls may become inadequate because of changes in conditions or deterioration in the degree of compliance with policies or procedures.

Changes in internal controls
 
There were no changes in our internal control over financial reporting (as defined in Rules 13a-15f and 15d-15f under the Exchange Act) that occurred during the quarter ended December 31, 2013 that have materially affected, or that are reasonably likely to materially affect, our internal control over financial reporting.

Item 11.	Executive Compensation
 
Compensation Discussion and Analysis
 
The primary goals of the Compensation Committee of our Board of Directors with respect to executive compensation are to attract and retain the most talented and dedicated executives possible, to tie annual and long-term cash and stock incentives to achievement of specified performance objectives, and to align executives’ incentives with shareholder value creation. To achieve these goals, the Compensation Committee implements and maintains compensation plans that tie a portion of executives’ overall compensation to key strategic goals such as developments in our clinical path, the establishment of key strategic collaborations, the build-up of our pipeline and the strengthening of our financial position. The Compensation Committee evaluates individual executive performance with a goal of setting compensation at levels the committee believes are comparable with executives in other companies of similar size and stage of development operating in the biotechnology industry while taking into account our relative performance and our own strategic goals.
 
Elements of Compensation
 
Executive compensation consists of following elements:
 
Base Salary. Base salaries for our executives are established based on the scope of their responsibilities taking into account competitive market compensation paid by other companies for similar positions. Generally, we believe that executive base salaries should be targeted near the median of the range of salaries for executives in similar positions with similar responsibilities at comparable companies. We did not make any changes to the compensation of our executive officers during 2013. The companies reviewed by the Compensation Committee in making compensation recommendations to our Board of Directors in 2012 include, among others, the following companies:
 
 	·	InterMune, Inc.	
 	·	Vivus, Inc.	
 	·	Biomarin Pharmaceutical Inc.	
 	·	Rigel Pharmaceuticals, Inc.	
 	·	Momenta Pharmaceuticals, Inc.	
 	·	Nektar Therapeutics	
 	·	Theravance, Inc.	
 	·	Dendreon Corp.	
 
The Compensation Committee intends to continue reviewing and revising the peer group periodically to ensure that it continues to reflect companies similar to our company in size and development stage. The Compensation Committee also reviews an executive compensation report and analysis of publicly-traded biotechnology companies prepared by third party experts from a well-known consulting firm for additional data and other information regarding executive compensation for comparative purposes.
 
71	

 	
  
Base salaries are usually reviewed annually, and adjusted from time to time to realign salaries with market levels after taking into account individual responsibilities, performance and experience. The base salaries of each of our President and Chief Executive Officer, our Executive Vice President, Research and Development, our Senior Vice President, Product Development, our Vice President and Chief Financial Officer and our Chief Operating Officer, who we refer to collectively as the “Named Executive Officers.” On July 15, 2012, our Board of Directors adopted certain recommendations of the Compensation Committee regarding the compensation of our Named Executive Officers with no change in the base salary component.
 
Annual Bonus. The Compensation Committee has the authority to award discretionary annual bonuses to our executive officers. The discretionary annual bonus awards were intended to compensate officers for achieving financial, clinical, regulatory and operational goals and for achieving individual annual performance objectives. For any given year, the compensation objectives vary, but relate generally to strategic factors such as developments in our clinical path, the execution of a license agreement for the commercialization of product candidates, the establishment of key strategic collaborations, the build-up of our pipeline and financial factors such as capital raising. Bonuses are awarded generally based on corporate performance, with adjustments made within a range for individual performance, at the discretion of the Compensation Committee. The Compensation Committee determines, on a discretionary basis, the size of the entire bonus pool and the amount of the actual award to each Named Executive Officer.
 
The Compensation Committee selects, in its discretion, the executive officers of our company or our subsidiary who are eligible to receive bonuses for any given year. Any bonus granted by the Compensation Committee will generally be paid in the first quarter of the year, unless such bonus was, by its terms, made payable upon the achievement of a specific milestone. The Compensation Committee has not fixed a minimum or maximum award for any executive officer’s annual discretionary bonus, unless specified in the officer’s employment agreement.
 
Each of our executive officers is eligible for a discretionary annual bonus under his or her employment agreement. The Compensation Committee has not fixed a minimum or a maximum amount for any officer’s annual discretionary bonus, nor is any executive officer entitled to a minimum or maximum bonus amount under his or her employment agreement.
 
In 2010, the Compensation Committee established a formal bonus plan that included, among other matters, bonuses payable to our Named Executive Officers upon the approval of taliglucerase alfa by the FDA. Accordingly, the following bonuses were paid in 2012 in connection with the May 2012 approval of taliglucerase alfa:
 
Named Executive Officer	 	Bonus Amount	 	
David Aviezer, Ph.D., MBA	 	$	400,000	 	
Yoseph Shaaltiel, Ph.D.	 	$	140,000	 	
Einat Brill Almon, Ph.D.	 	$	140,000	 	
Yossi Maimon	 	$	140,000	 	
Total	 	$	820,000	 	
 
Following the adoption of the 2010 bonus plan, the Compensation Committee elected to refrain from issuing additional bonuses to our Named Executive Officers until the FDA approved taliglucerase alfa. On July 15, 2012, our Board of Directors adopted certain recommendations of the Compensation Committee regarding the compensation of our Named Executive Officers, including the grant of certain incentive bonuses to be paid to them upon the achievement of a number of designated milestones, as set forth below. In addition, our Board of Directors approved the grant of restricted stock to our Named Executive Officers, as described below, and to other members of our management team. The bonus amounts were determined by the Compensation Committee, in its discretion after review materials regarding peer companies, review with our legal counsel and review of materials provided by accounting firms.

In addition to the bonuses granted to our Named Executive Officers, additional members of our management team are entitled to certain incentive bonuses payable upon the achievement of designated milestones. If we achieve agreed-upon advancements in the clinical development of each of certain designated product candidates during an agreed-upon amount of time immediately following the Board of Director’s approval of the bonuses, our Named Executive Officers will be entitled to the amounts listed in the first two columns of the table set forth above. The amounts are payable upon achievement of the applicable milestone if, at such time, we have available an agreed-upon minimum cash balance. If we do not have the minimum cash balance, the bonuses will be considered earned, and will be payable when we next achieve the minimum cash balance.
The grants of restricted stock to the Named Executive Officers in 2012 consist of 1,100,000 shares, in the aggregate, as shown in the table immediately following this paragraph. The grants were made in accordance with the terms and conditions of our amended 2006 stock incentive plan.
 
Named Executive Officer	 	 	Number of Restricted Shares	 	
David Aviezer, Ph.D.	 	 	418,000	 	
Yoseph Shaaltiel, Ph.D.	 	 	210,000	 	
Einat Brill Almon, Ph.D.	 	 	185,000	 	
Yossi Maimon, CPA	 	 	185,000	 	
Tzvi Palash	 	 	102,000	 	
 
The restricted shares detailed above vest in 16 equal, quarterly increments over a four-year period, commencing upon the date of grant. In addition, each vested share is subject to a 24-month lock-up period, commencing upon the applicable vesting date. Immediately and automatically in the event of a Change in Control, all of the restricted shares listed above shall vest and the lock-up periods shall terminate, subject to certain exceptions.
 
Options and Share-Based Compensation. Our amended 2006 stock incentive plan authorizes us to grant options to purchase shares of common stock, restricted stock and other securities to our employees, directors and consultants. Our Compensation Committee is the administrator of the stock incentive plan. Stock option or other grants are generally made at the commencement of employment and following a significant change in job responsibilities or to meet other special retention or performance objectives. The Compensation Committee reviews and approves stock option and other awards to executive officers based upon a review of competitive compensation data, its assessment of individual performance, a review of each executive’s existing long-term incentives, and retention considerations. The exercise price of stock options granted under our amended 2006 stock incentive plan must be equal to at least 100% of the fair market value of our common stock on the date of grant; however, in certain circumstances, grants may be made at a lower price to Israeli grantees who are residents of the State of Israel.
 
73	

 	
 
Severance and Change in Control Benefits. Pursuant to the employment agreements entered into with each of our executive officers based in Israel, the executive officer is entitled to be insured by Protalix Ltd. under a Manager’s Policy in lieu of severance. The intention of such Manager’s Policies is to provide the Israel-based officers with severance protection of one month’s salary for each year of employment. In addition, stock option and other agreements with each of our Named Executive Officers, as amended, provide that all of the outstanding options and other securities granted by us to each Named Executive Officer are subject to accelerated vesting immediately upon a change in control of our company. As set forth above, our Board of Directors adopted certain recommendations of the Compensation Committee on July 15, 2012, regarding the compensation of our Named Executive Officers, including cash bonuses for Named Executive Officers if we complete a Change in Control transaction.
 
Other Compensation. Consistent with our compensation philosophy, we intend to continue to maintain our current benefits for our executive officers; however, the Compensation Committee in its discretion may revise, amend, or add to the officer’s executive benefits if it deems it advisable. As an additional benefit to all of our Israel-based Named Executive Officers and for most of our employees, we generally contribute to certain funds amounts equaling a total of approximately 15% of their gross salaries for certain pension and other savings plans for the benefit of the Named Executive Officers. In addition, in accordance with customary practice in Israel, our Israel-based executives’ agreements require us to contribute towards their vocational studies, and to provide annual recreational allowances, a company car and a company phone. We believe these benefits are currently equivalent with median competitive levels for comparable companies.
 
Executive Compensation. We refer to the “Summary Compensation Table” set forth in Section 11 of the Annual Report on Form 10-K for information regarding the compensation earned during the fiscal year ended December 31, 2013 by: our President and Chief Executive Officer, our Executive Vice President, Research and Development, our Senior Vice President, Product Development, our Vice President and Chief Financial Officer and our Chief Operating Officer, who we refer to collectively as the “Named Executive Officers.”

Potential Payments upon Termination or Change-in-Control
 
Each of our Named Executive Officers is entitled to be insured by Protalix Ltd. under a Manager’s Policy in lieu of severance upon termination. The intention of such Manager’s Policies is to provide the Israel-based officers with severance protection of one month’s salary for each year of employment. We do not provide any change in control benefits to our Named Executive Officers except for certain cash bonuses and the acceleration of the vesting periods for outstanding options and restricted stock, subject to certain conditions. Since as of December 31, 2013 all options held by each of Dr. Aviezer, Dr. Shaaltiel, Dr. Brill Almon, Mr. Maimon have been fully vested on such date, and the options held by Mr. Palash had exercise price higher than the closing price on that date, if we had experienced a change of control on December 31, 2013, the value of the acceleration of the stock options held by each of Dr. Aviezer, Dr. Shaaltiel, Dr. Brill Almon, Mr. Maimon and Mr. Palash would be zero. Had we experienced a change of control on December 31, 2013, the value of the acceleration of the shares of restricted stock held by each of Dr. Aviezer, Dr. Shaaltiel, Dr. Brill Almon, Mr. Maimon and Mr. Palash would be $1,117,889, $561,619, $494,759, $494,759 and $272,786, respectively.

Amended 2006 Stock Incentive Plan
 
Our Board of Directors and a majority of our shareholders approved our 2006 Stock Incentive Plan on December 14, 2006. Our shareholders approved an amendment to the plan on June 17, 2012. There are 11,341,655 shares of our common stock reserved for issuance, in the aggregate, under the amended 2006 Stock Incentive Plan, subject to adjustment for a stock split or any future stock dividend or other similar change in our common stock or our capital structure. As of December 31, 2013, options to acquire 215,378 shares of common stock remain available for grant under the amended 2006 Stock Incentive Plan.
 
Our amended 2006 Stock Incentive Plan provides for the grant of stock options, restricted stock, restricted stock units, stock appreciation rights and dividend equivalent rights, collectively referred to as “awards.” Stock options granted under the amended 2006 Stock Incentive Plan may be either incentive stock options under the provisions of Section 422 of the Internal Revenue Code, or non-qualified stock options. Incentive stock options may be granted only to employees. Awards other than incentive stock options may be granted to employees, directors and consultants.
 
77	

 	
  
The amended 2006 Stock Incentive Plan is also designed to comply with the provisions of the Israeli Income Tax Ordinance New Version, 1961 (including as amended pursuant to Amendment 132 thereto) (the “tax ordinance”) and is intended to enable us to grant awards to grantees who are Israeli residents as follows: (i) awards to employees pursuant to Section 102 of the tax ordinance; and (ii) awards to non-employees pursuant to Section 3(I) of the tax ordinance. For this purpose, “employee” refers only to employees, office holders and directors of our company or a related entity excluding those who are considered “Controlling Shareholders” pursuant to, or otherwise excluded by, the tax ordinance. In accordance with the terms and conditions imposed by the Tax Ordinance, grantees who receive awards under the amended 2006 stock incentive plan may be afforded certain tax benefits in Israel as described below.
 
Our Board of Directors or the Compensation Committee, referred to as the “plan administrator,” will administer our amended 2006 stock incentive plan, including selecting the grantees, determining the number of shares to be subject to each award, determining the exercise or purchase price of each award, and determining the vesting and exercise periods of each award.
 
The exercise price of stock options granted under the 2006 stock incentive plan must be equal to at least 100% of the fair market value of our common stock on the date of grant; however, in certain circumstances, grants may be made at a lower price to Israeli grantees who are residents of the State of Israel. If, however, incentive stock options are granted to an employee who owns stock possessing more than 10% of the voting power of all classes of our stock or the stock of any parent or subsidiary of our company, the exercise price of any incentive stock option granted must equal at least 110% of the fair market value on the grant date and the maximum term of these incentive stock options must not exceed five years. The maximum term of all other awards must not exceed 10 years (or five years in the case of an incentive stock option granted to any participant who owns stock representing more than 10% of the voting power of all classes of our stock or the stock of any parent or subsidiary of our company). The plan administrator will determine the exercise or purchase price (if any) of all other awards granted under the amended 2006 stock incentive plan.
 
Under the amended 2006 stock incentive plan, incentive stock options and options to Israeli grantees may not be sold, pledged, assigned, hypothecated, transferred or disposed of in any manner other than by will or by the laws of descent or distribution and may be exercised during the lifetime of the participant only by the participant. Other awards shall be transferable by will or by the laws of descent or distribution and to the extent and in the manner authorized by the plan administrator by gift or pursuant to a domestic relations order to members of the participant’s immediate family. The amended 2006 stock incentive plan permits the designation of beneficiaries by holders of awards, including incentive stock options.
 
If the service of a participant in the amended 2006 stock incentive plan is terminated for any reason other than cause, the participant may exercise awards that were vested as of the termination date for a period ending upon the earlier of 12 months from the date of termination (or such shorter or longer period set forth in the award agreement) or the expiration date of the awards unless otherwise determined by the plan administrator. If the service of a participant in the amended 2006 stock incentive plan is terminated for cause, the participant may exercise awards that were vested as of the termination date for a period ending upon the earlier of 14 days from the date of termination (or such shorter or longer period set forth in the award agreement) or the expiration date of the awards unless otherwise determined by the plan administrator.
 
In the event of a corporate transaction, all awards will terminate unless assumed by the successor corporation. Unless otherwise provided in a participant’s award agreement, in the event of a corporate transaction and with respect to the portion of each award that is assumed or replaced, then such portion will automatically become fully vested and exercisable immediately upon termination of a participant’s service if the participant is terminated by the successor company or us without cause within 12 months after the corporate transaction. With respect to the portion of each award that is not assumed or replaced, such portion will automatically become fully vested and exercisable immediately prior to the effective date of the corporate transaction so long as the participant’s service has not been terminated prior to such date.
 
In the event of a change in control, except as otherwise provided in a participant’s award agreement, following a change in control (other than a change in control that also is a corporate transaction) and upon the termination of a participant’s service without cause within 12 months after a change in control, each award of such participant that is outstanding at such time will automatically become fully vested and exercisable immediately upon the participant’s termination. In addition, the stock options and shares of restricted stock issued to each of our Named Executive Officers are subject to accelerated vesting immediately upon a change in control of our company, as defined in our amended 2006 stock incentive plan.
 
Under our amended 2006 stock incentive plan, a corporate transaction is generally defined as:
 
·     a merger or consolidation in which we are not the surviving entity, except for the principal purpose of changing our company’s state of incorporation;
 
78	

 	

·     the sale, transfer or other disposition of all or substantially all of our assets;
 
·     the complete liquidation or dissolution of our company;
 
·     any reverse merger in which we are the surviving entity but our shares of common stock outstanding immediately prior to such merger are converted or exchanged by virtue of the merger into other property, whether in the form of securities, cash or otherwise, or in which securities possessing more than forty percent (40%) of the total combined voting power of our outstanding securities are transferred to a person or persons different from those who held such securities immediately prior to such merger; or
 
·     acquisition in a single or series of related transactions by any person or related group of persons of beneficial ownership of securities possessing more than fifty percent (50%) of the total combined voting power of our outstanding securities but excluding any such transaction or series of related transactions that the plan administrator determines not to be a corporate transaction (provided however that the plan administrator shall have no discretion in connection with a corporate transaction for the purchase of all or substantially all of our shares unless the principal purpose of such transaction is changing our company’s state of incorporation).
 
Under our amended 2006 stock incentive plan, a change of control is defined as:
 
·     the direct or indirect acquisition by any person or related group of persons of beneficial ownership of securities possessing more than fifty percent (50%) of the total combined voting power of our outstanding securities pursuant to a tender or exchange offer made directly to our shareholders and which a majority of the members of our board (who have generally been on our board for at least 12 months) who are not affiliates or associates of the offeror do not recommend shareholders accept the offer; or
 
·	a change in the composition of our board over a period of 12 months or less, such that a majority of our board members ceases, by reason of one or more contested elections for board membership, to be comprised of individuals who were previously directors of our company.
 
Unless terminated sooner, the amended 2006 stock incentive plan will automatically terminate in 2016. Our Board of Directors has the authority to amend, suspend or terminate our amended 2006 stock incentive plan. No amendment, suspension or termination of the amended 2006 stock incentive plan shall adversely affect any rights under awards already granted to a participant. To the extent necessary to comply with applicable provisions of federal securities laws, state corporate and securities laws, the Internal Revenue Code, the rules of any applicable stock exchange or national market system, and the rules of any non-U.S. jurisdiction applicable to awards granted to residents therein (including the Tax Ordinance), we shall obtain shareholder approval of any such amendment to the 2006 stock incentive plan in such a manner and to such a degree as required.
 
Impact of Israeli Tax Law
 
The awards granted to employees pursuant to Section 102 of the Tax Ordinance under the amended 2006 stock incentive plan may be designated by us as approved options under the capital gains alternative, or as approved options under the ordinary income tax alternative.
 
To qualify for these benefits, certain requirements must be met, including registration of the options in the name of a trustee. Each option, and any shares of common stock acquired upon the exercise of the option, must be held by the trustee for a period commencing on the date of grant and deposit into trust with the trustee and ending 24 months thereafter.
 
Under the terms of the capital gains alternative, we may not deduct expenses pertaining to the options for tax purposes.
 
Under the amended 2006 stock incentive plan, we may also grant to employees options pursuant to Section 102(c) of the Tax Ordinance that are not required to be held in trust by a trustee. This alternative, while facilitating immediate exercise of vested options and sale of the underlying shares, will subject the optionee to the marginal income tax rate of up to 50% as well as payments to the National Insurance Institute and health tax on the date of the sale of the shares or options. Under the 2006 stock incentive plan, we may also grant to non-employees options pursuant to Section 3(I) of the Tax Ordinance. Under that section, the income tax on the benefit arising to the optionee upon the exercise of options and the issuance of common stock is generally due at the time of exercise of the options.
 
79	

 	
 
These options shall be further subject to the terms of the tax ruling that has been obtained by Protalix Ltd. from the Israeli tax authorities in connection with the merger. Under the tax ruling, the options issued by us in connection with the assumption of Section 102 options previously issued by Protalix Ltd. under the capital gains alternative shall be issued to a trustee, shall be designated under the capital gains alternative and the issuance date of the original options shall be deemed the issuance date for the assumed options for the calculation of the respective holding period.

Compensation Committee Interlocks and Insider Participation
 
Our Compensation Committee currently consists of Messrs. Bar Shalev and Sheratzky and Mrs. Harel Buchris. No member of our Compensation Committee or any executive officer of our company or of Protalix Ltd. has a relationship that would constitute an interlocking relationship with executive officers or directors of another entity. No Compensation Committee member is or was an officer or employee of ours or of Protalix Ltd. Further, none of our executive officers serves on the board of directors or compensation committee of any entity that has one or more executive officers serving as a member of our Board of Directors or Compensation Committee.

Item 12.       Security Ownership of Certain Beneficial Owners and Management and Related Stockholder Matters
 
Security Ownership of Certain Beneficial Owners and Management
 
The following table sets forth information, as of March 1, 2014, regarding beneficial ownership of our common stock:
 
 	·	each person who is known by us to own beneficially more than 5% of our common stock;	
 
 	·	each director;	
 
 	·	each of our Chief Executive Officer, our Executive Vice President, Research and Development, our Senior Vice President, Product Development, our Chief Financial Officer, our Vice President, Sales and Commercial Affairs and our Chief Operating Officer; and	
 
 	·	all of our directors and executive officers collectively.	
 
Unless otherwise noted, we believe that all persons named in the table have sole voting and investment power with respect to all shares of our common stock beneficially owned by each of them. For purposes of these tables, a person is deemed to be the beneficial owner of securities that can be acquired by such person within 60 days from March 1, 2014 upon exercise of options, warrants and convertible securities.

Item 13.     Certain Relationships and Related Transactions, and Director Independence
 
On September 14, 2006, Protalix Ltd. entered into a collaboration and licensing agreement with Teva for the development and manufacture of two proteins using ProCellEx, our proprietary protein expression system. Mr. Hurvitz, our former Chairman, was the chairman of Teva’s board of directors when we entered into the agreement. Professor Kornberg, a member of our Board of Directors also previously served on Teva’s board of directors. The agreement provides that we will collaborate with Teva on the research and development of two proteins using ProCellEx. We and Teva identified two proteins for research and development activities under the agreement, but in 2009 both of the projects were terminated for commercial reasons.
 
All related party transactions are reviewed and approved by the Audit Committee, as required by the Audit Committee Charter.
 
Corporate Governance and Independent Directors
 
In compliance with the listing requirements of the NYSE MKT, we have a comprehensive plan of corporate governance for the purpose of defining responsibilities, setting high standards of professional and personal conduct and assuring compliance with such responsibilities and standards. We currently regularly monitor developments in the area of corporate governance to ensure we are in compliance with the standards and regulations required by the NYSE MKT. A summary of our corporate governance measures follows.
 
Independent Directors
 
We believe a majority of the members of our Board of Directors are independent from management. When making determinations from time to time regarding independence, the Board of Directors will reference the listing standards adopted by the NYSE MKT as well as the independence standards set forth in the Sarbanes-Oxley Act of 2002 and the rules and regulations promulgated by the Commission under that Act. In particular, our Audit Committee periodically evaluates and reports to the Board of Directors on the independence of each member of the Board. We anticipate our audit committee will analyze whether a director is independent by evaluating, among other factors, the following:
 
·     Whether the member of the Board of Directors has any material relationship with us, either directly, or as a partner, shareholder or officer of an organization that has a relationship with us;
 
·     Whether the member of the Board of Directors is a current employee of our company or any of our subsidiaries, or was an employee of our company or any of our subsidiaries within three years preceding the date of determination;
 
·     Whether the member of the Board of Directors is, or in the three years preceding the date of determination has been, affiliated with or employed by (i) a present internal or external auditor of our company or any affiliate of such auditor or (ii) any former internal or external auditor of our company or any affiliate of such auditor, which performed services for us within three years preceding the date of determination;
 
83	

 	
  
·     Whether the member of the Board of Directors is, or in the three years preceding the date of determination has been, part of an interlocking directorate, in which any of our executive officers serve on the Compensation Committee of another company that concurrently employs the member as an executive officer;
 
·     Whether the member of the Board of Directors receives any compensation from us, other than fees or compensation for service as a member of the Board of Directors and any committee of the Board of Directors and reimbursement for reasonable expenses incurred in connection with such service and for reasonable educational expenses associated with Board of Directors or committee membership matters;
 
·     Whether an immediate family member of the member of the Board of Directors is a current executive officer of our company or was an executive officer of our company within three years preceding the date of determination;
 
·     Whether an immediate family member of the member of the Board of Directors is, or in the three years preceding the date of determination has been, affiliated with or employed in a professional capacity by (i) a present internal or external auditor of ours or any of our affiliates or (ii) any former internal or external auditor of our company or any affiliate of ours which performed services for us within three years preceding the date of determination; and
 
·     Whether an immediate family member of the member of the Board of Directors is, or in the three years preceding the date of determination has been, part of an interlocking directorate, in which any of our executive officers serve on the Compensation Committee of another company that concurrently employs the immediate family member of the member of the Board of Directors as an executive officer.
 
The above list is not exhaustive and we anticipate that the Audit Committee will consider all other factors which could assist it in its determination that a director will have no material relationship with us that could compromise that director’s independence.
 
Under these standards, our Board of Directors has determined that Messrs. Bar Shalev and Sheratzky and Mrs. Harel Buchris are considered “independent” pursuant to the rules of the NYSE MKT and Section 10A(m)(3) of the Exchange Act. In addition, our Board of Directors has determined that at least two of these directors are able to read and understand fundamental financial statements and have substantial business experience that results in their financial sophistication, qualifying them for membership on our audit committee. Our Board of Directors has also determined that Messrs. Bar Shalev, Bronfeld and Sheratzky, Mrs. Harel Buchris and Dr. Kornberg are “independent” pursuant to the rules of the NYSE MKT.
 
The position of chairman of the board is not held by our chief executive officer at this time. The Board of Directors does not have a policy mandating the separation of these functions. We believe it is in our best interest that Mr. Bronfeld serve as the interim chairman of the board. This decision was based on Mr. Bronfeld’s experience in the healthcare industry in Israel and globally and his years of experience serving on the board of directors of many public and private companies. Our non-management directors hold formal meetings, separate from management, at least twice per year. We have no formal policy regarding attendance by our directors at annual shareholders meetings, although we encourage such attendance and anticipate most of our directors will attend these meetings. Messrs. Bronfeld and Bar Shalev, Dr. Aviezer and Dr. Shaaltiel attended our 2013 annual meeting of shareholders.
 
The Board’s Role in Risk Oversight
 
Our Board of Directors oversees an enterprise-wide approach to risk management, designed to support the achievement of business objectives, including organizational and strategic objectives, to improve long-term organizational performance and enhance shareholder value. The involvement of our Board of Directors in setting our business strategy is a key part of its assessment of management’s plans for risk management and its determination of what constitutes an appropriate level of risk for the company. The participation of our Board of Directors in our risk oversight process includes receiving regular reports from members of senior management on areas of material risk to our company, including operational, financial, legal and regulatory, and strategic and reputational risks. While the full board has the ultimate oversight responsibility for the risk management process, various committees of the board also have responsibility for risk management. For example, financial risks, including internal controls, are overseen by the audit committee and risks that may be implicated by our executive compensation programs are overseen by the compensation committee. Upon identification of a risk, the assigned board committee or our full Board of Directors discuss or review risk management and risk mitigation strategies. Additional review or reporting on enterprise risks is conducted as needed or as requested by our Board of Directors or a committee thereof.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
 
To the shareholders of
 
PROTALIX BIOTHERAPEUTICS, INC.
 
In our opinion, the accompanying consolidated balance sheets and the related statements of operations, changes in capital deficiency and cash flows present fairly, in all material respects, the financial position of Protalix BioTherapeutics, Inc. and its subsidiaries at December 31, 2013 and 2012, and the results of their operations and their cash flows for each of the three years in the period ended December 31, 2013, in conformity with accounting principles generally accepted in the United States of America. Also, in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2013, based on criteria established in Internal Control - Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (1992). The Company’s management is responsible for these financial statements, for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying “Management Report on Internal Control over Financial Reporting” appearing under Item 9A. Our responsibility is to express opinions on these financial statements and on the Company’s internal control over financial reporting based on our integrated audits. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements are free of material misstatement and whether effective internal control over financial reporting was maintained in all material respects. Our audits of the financial statements included examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.
 
A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that: (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of the company’s assets that could have a material effect on the financial statements.
 
Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

NOTE 1 - SIGNIFICANT ACCOUNTING POLICIES
 
 	a.	General	
 
Protalix BioTherapeutics, Inc. (collectively with its subsidiaries, the “Company”), and its wholly-owned subsidiary, Protalix Ltd., are biopharmaceutical companies focused on the development and commercialization of recombinant therapeutic proteins based on the Company’s proprietary ProCellEx® protein expression system (“ProCellEx”). In September 2009, Protalix Ltd. formed another wholly-owned subsidiary under the laws of the Netherlands, Protalix B.V., in connection with the European Medicines Agency (“EMA”) application process in the European Union. The Company’s two subsidiaries are referred to collectively herein as the “Subsidiaries.”
 
On May 1, 2012, the U.S. Food and Drug Administration (“FDA”) approved taliglucerase alfa for injection, the Company’s first approved drug product, as an enzyme replacement therapy (ERT) for the long-term treatment of adult patients with a confirmed diagnosis of type 1 Gaucher disease. Taliglucerase alfa is a proprietary, recombinant form of glucocerebrosidase (GCD) that the Company developed using ProCellEx. Taliglucerase alfa was also approved by the Israeli Ministry of Health (the “Israeli MOH”) in September 2012, by the Brazilian Ministry of Health (the “Brazilian MOH”) in March 2013 and by the applicable regulatory authorities of certain other countries. Taliglucerase alfa is the first plant cell-based recombinant therapeutic protein approved by the FDA or any other major regulatory authority.
 
Taliglucerase alfa is being marketed in the United States under the brand name ELELYSO by Pfizer Inc. (“Pfizer”), the Company’s commercialization partner, as provided in the exclusive license and supply agreement by and between Protalix Ltd. and Pfizer (the “Pfizer Agreement”). The Company, through Protalix Ltd., markets ELELYSO in Israel and in Brazil under the brand name UPLYSO.
 
Protalix Ltd. granted Pfizer an exclusive, worldwide license to develop and commercialize taliglucerase alfa under the Pfizer Agreement, but retained those rights in Israel and, since 2014, in Brazil (see below). The Company has agreed to a specific allocation between Protalix Ltd. and Pfizer regarding the responsibilities for the continued development efforts for taliglucerase alfa. To date, the Company has received an upfront payment of $60.0 million in connection with the execution of the Pfizer Agreement and shortly thereafter an additional $5.0 million clinical development-related milestone payment. The Company received during 2012 an additional $25.0 million milestone payment in connection with the FDA’s approval of taliglucerase alfa in the United States, which was considered to be a substantive milestone for purposes of revenue recognition, and, accordingly, was recorded as revenue during the period in which the milestone was achieved. The agreement provides that the Company share with Pfizer the net profits or loss related to the development and commercialization of taliglucerase alfa on a 40% and 60% basis, respectively, except with respect to the profits or losses related to commercialization efforts in Israel and Brazil, where the Company retained exclusive marketing rights. In calculating the net profits or losses under the agreement, there are certain agreed upon limits on the amounts that may be deducted from gross sales for certain expenses and costs of goods sold.
 
In December 2012, Protalix Ltd. entered into a Clinical Development Agreement with Pfizer under which Protalix Ltd. will continue to manage, administer and sponsor current, ongoing clinical trials relating to taliglucerase alfa. According to the terms of the agreement, Protalix Ltd. was eligible to receive a payment of $8.3 million upon the achievement of certain near-term clinical development goals. The goals were achieved, and the payment made, in December 2012. The Company evaluated the terms of the agreement and the nature of the payment made by Pfizer and concluded that the amount received represents an upfront funding of the anticipated costs of the Company’s ongoing clinical trials relating to taliglucerase alfa. Accordingly, the amount was deferred upon receipt and is recognized as a reduction of research and development expenses over the ongoing clinical trial period.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
NOTE 1 - SIGNIFICANT ACCOUNTING POLICIES (continued):
 
On June 18, 2013, Protalix Ltd. entered into a Supply and Technology Transfer Agreement (the “Brazil Agreement”) with Fundaçăo Oswaldo Cruz (“Fiocruz”), an arm of the Brazilian MOH, for taliglucerase alfa. The brand name for taliglucerase alfa in Brazil is UPLYSO TM . The first term of the technology transfer is seven years and the agreement may be extended for an additional five-year term, as needed, to complete the technology transfer. The technology transfer is designed to be effected in four stages and is intended to transfer to Fiocruz the capacity and skills required for the Brazilian government to construct its own manufacturing facility, at its sole expense, and to produce a sustainable, high quality, and cost effective supply of taliglucerase alfa. Under the agreement, Fiocruz has committed to purchase at least approximately $40 million worth of taliglucerase alfa during the first two years of the agreement. In subsequent years, Fiocruz is required to purchase at least approximately $40 million worth of taliglucerase alfa per year. Additionally, Protalix Ltd. is not required to complete the final stage of the technology transfer until Fiocruz purchases at least approximately $280 million worth of taliglucerase alfa. The Brazil agreement became effective in 2014.
 
To facilitate the arrangement with Fiocruz, Pfizer amended its exclusive license and supply agreement with Protalix Ltd. The amendment provides for the transfer of the commercialization and other rights to taliglucerase alfa in Brazil back to Protalix Ltd. As consideration for the transfer of the commercialization and supply rights, Protalix Ltd. agreed to pay Pfizer a maximum amount of approximately $12.5 million from its net profits (as defined in the license and supply agreement) per year. Pfizer has also agreed to perform certain transitional services in Brazil on Protalix Ltd.’s behalf in connection with the supply of taliglucerase alfa to Fiocruz.
 
Protalix Ltd. is required to pay a fee equal to 5% of the net proceeds generated in Brazil to its agent for services provided in assisting Protalix Ltd. complete the Brazil Agreement pursuant to an agency agreement between Protalix Ltd. and the agent. The agency agreement will remain in effect with respect to the Brazil Agreement until the termination thereof.
 
In addition to the approvals from the FDA, the Israeli MOH and the Brazilian MOH, marketing approval has been granted to UPLYSO in Mexico, Chile and Uruguay. In addition, the Company is cooperating with Pfizer in its efforts to obtain marketing approval for taliglucerase alfa in additional countries and jurisdictions. Currently, marketing authorization applications have been filed in a number of countries.
 
Currently, patients are being treated with taliglucerase alfa on a commercial basis in the United States, Brazil and Israel. In addition, patients are being treated globally through the Company’s clinical trials and related studies, compassionate use programs and other programs. On July 13, 2010, the Company announced that the French regulatory authority had granted an Autorisation Temporaire d’Utilisation (ATU), or Temporary Authorization for Use, for taliglucerase alfa for the treatment of Gaucher disease.
 
An ATU is the regulatory mechanism used by the French Health Products and Safety Agency to make non-approved drugs available to patients in France when a genuine public health need exists. This ATU allows Gaucher patients in France to receive treatment with taliglucerase alfa before marketing authorization for the product is granted in the European Union. Payment for taliglucerase alfa has been secured through government allocations to hospitals. In addition, taliglucerase alfa is currently being provided to Gaucher patients under special access agreements or named patient provisions in other countries.
 
In addition to taliglucerase alfa, the Company is working on the development of certain other products using ProCellEx.
 
In addition to the approval of taliglucerase alfa for marketing in the United States, Israel, Brazil, Mexico and other countries, successful completion of the Company’s development programs and its transition to normal operations is dependent upon obtaining the foreign regulatory approvals required to sell its products internationally. A substantial amount of time may pass before the Company achieves a level of revenues adequate to support its operations, if at all, and the Company expects to incur substantial expenditures in connection with the regulatory approval process for each of its product candidates during their respective developmental periods.

PROTALIX BIOTHERAPEUTICS, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
NOTE 1 - SIGNIFICANT ACCOUNTING POLICIES (continued):
 
Obtaining marketing approval with respect to any product candidate in any country is directly dependent on the Company’s ability to implement the necessary regulatory steps required to obtain such approvals. The Company cannot reasonably predict the outcome of these activities.
 
 	b.	Basis of presentation	
 
The Company’s financial statements have been prepared in accordance with generally accepted accounting principles in the United States (“U.S. GAAP”).
 
 	c.	Use of estimates in the preparation of financial statements	
 
The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results may differ from those estimates.
 
 	d.	Functional currency	
 
The dollar is the currency of the primary economic environment in which the operations of the Company and its Subsidiaries are conducted. Most of the Company’s revenues are derived in dollars. Most of the Company’s expenses and capital expenditures are incurred in dollars, and the major source of the Company’s financing has been provided in dollars.
 
Transactions and balances originally denominated in dollars are presented at their original amounts. Balances in non-dollar currencies are translated into dollars using historical and current exchange rates for non-monetary and monetary balances, respectively. For non-dollar transactions and other items (stated below) reflected in the statements of operations, the following exchange rates are used: (i) for transactions - exchange rates at the transaction dates or average rates; and (ii) for other items (derived from non-monetary balance sheet items such as depreciation and amortization, etc.) - historical exchange rates. Currency transaction gains and losses are carried to financial income or expenses, as appropriate.
 
 	e.	Cash equivalents	
 
The Company considers all short-term, highly liquid investments, which include short-term bank deposits with original maturities of three months or less from the date of purchase, that are not restricted as to withdrawal or use and are readily convertible to known amounts of cash, to be cash equivalents.
 
 	f.	Inventories	
 
Inventories are valued at the lower of cost or market. Cost of raw and packaging materials and purchased products is determined using the “moving average” basis.
 
Cost of finished products that are capitalized is determined as follows: the value of the raw and packaging materials component is determined primarily on a using the “moving average” basis; the value of the labor and overhead component is determined on an average basis over the production period.
 
Prior to the FDA’s approval of taliglucerase alfa, manufacturing costs related to taliglucerase alfa were not capitalized; rather, such costs were expensed as research and development expenses. Effective as of the FDA approval of taliglucerase alfa on May 1, 2012, the Company capitalizes manufacturing costs associated with taliglucerase alfa.
 
If actual market prices for finished products prove less favorable than those projected by management, inventory write-downs may be required. Inventory is written down for estimated obsolescence based upon management assumptions about future demand and market conditions.

PROTALIX BIOTHERAPEUTICS, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
NOTE 1 - SIGNIFICANT ACCOUNTING POLICIES (continued):
 
 	g.	Property and equipment	
 
 	1.	Property and equipment are stated at cost, net of accumulated depreciation and amortization.	
 
 	2.	The Company’s assets are depreciated by the straight-line method on the basis of their estimated useful lives as follows:	
  
 	Years	
Laboratory equipment	5	
Furniture	10-15	
Computer equipment  	3	
 
Leasehold improvements are amortized by the straight-line method over the expected lease term, which is shorter than the estimated useful life of the improvements.
 
 	h.	Impairment in value of long-lived assets:	
 
The Company tests long-lived assets for impairment if an indication of impairment exists. If the sum of expected future cash flows of definite life assets (undiscounted and without interest charges) is less than the carrying amount of such assets, the Company recognizes an impairment loss, and writes down the assets to their estimated fair values.
 
 	i.	Income taxes	
 
 	1.	Deferred income taxes	
 
Deferred taxes are determined utilizing the assets and liabilities method based on the estimated future tax effects of the differences between the financial accounting and tax bases of assets and liabilities under the applicable tax laws. Deferred tax balances are computed using the tax rates expected to be in effect when those differences reverse. A valuation allowance in respect of deferred tax assets is provided if, based upon the weight of available evidence, it is more likely than not that some or all of the deferred tax assets will not be realized. The Company has provided a full valuation allowance with respect to its deferred tax assets.
 
The guidance prohibits the recognition of deferred tax liabilities or assets that arise from differences between the financial reporting and tax bases of assets and liabilities that are measured from the local currency into dollars using historical exchange rates, and that result from changes in exchange rates or indexing for tax purposes. Consequently, the above mentioned differences with respect to Protalix Ltd. were not reflected in the computation of deferred tax assets and liabilities.
 
 	2.	Uncertainty in income taxes	
 
Tax benefits recognized in the financial statements are those that the Company’s management deems at least more likely than not to be sustained, based on technical merits. The amount of benefits recorded for these tax benefits is measured as the largest benefit the Company’s management deems more likely than not to be sustained.
 
 	j.	Revenue Recognition	
 
The Company recognizes revenue when the earnings process is complete, which is when revenue is realized or realizable and earned, there is persuasive evidence a revenue arrangement exists, delivery of goods or services has occurred, the sales price is fixed or determinable and collectability is reasonably assured.

PROTALIX BIOTHERAPEUTICS, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
NOTE 1 - SIGNIFICANT ACCOUNTING POLICIES (continued):
 
 	1.	Revenues from the license and supply agreement with Pfizer	
 
The Company recognizes revenue from milestone payments received pursuant to the Pfizer Agreement in accordance with guidance regarding revenue recognition and accounting for revenue arrangements with multiple deliverables. As the arrangement with Pfizer requires the Company’s continued involvement with respect to the proposed commercialization of taliglucerase alfa, the non-refundable, up-front license payment the Company received from Pfizer was deferred and recognized over the related performance period. The Company estimated the performance period of 14 years (commencing upon the date of the Company’s receipt of the up-front license payment payable by Pfizer under the Pfizer Agreement) based on the date the last relevant patent expires. See Note 2. The Company adjusts the performance periods, if appropriate, based on the applicable facts and circumstances. Each milestone payment that is considered to be substantive for purposes of revenue recognition is recorded as revenue during the period during which the milestone is achieved.
 
 	2.	Revenues from selling products	
 
The Company recognizes revenues from selling products upon delivery, when the sales price is fixed or determinable and collectability is reasonably assured.
 
 	3.	Company’s share in the collaboration agreement	
 
Under the terms and conditions of the Pfizer Agreement, the Company is entitled to 40% of the profits or loss from sales of taliglucerase alfa, and related expenses incurred, except with respect to sales in Israel and Brazil (since 2014), where the Company retained exclusive marketing rights. Since Pfizer bears most of the risks and rewards relating to the agreement, the Company’s share in the profits and loss in the agreement is recognized on a net basis. The Company recognizes its share of net profit or loss from the Pfizer Agreement based on reports it receives from Pfizer summarizing the results of the collaborative activities under the agreement for the applicable period. Under the terms of the Pfizer Agreement, for its subsidiaries operating outside the United States, financial information is included based on the fiscal year ending November 30, while financial information for the U.S. entity is included based on the fiscal year ending December 31.
 
 	k.	Research and development costs	
 
Research and development costs are expensed as incurred and consist primarily of personnel, subcontractors and consultants (mainly in connection with clinical trials), facilities, equipment and supplies for research and development activities. Grants received by the Israeli Subsidiary from the Office of the Chief Scientist of Israel’s Ministry of Industry, Trade and Labor (the “OCS”) are recognized when the grant becomes receivable, provided there is reasonable assurance that the Company or the Subsidiary will comply with the conditions attached to the grant and there is reasonable assurance the grant will be received. The grant is deducted from the research and development expenses as the applicable costs are incurred.
 
Reimbursements received from Pfizer are recognized when the reimbursements become receivable, provided there is reasonable assurance that the Company will comply with the conditions attached to the reimbursements and there is reasonable assurance the reimbursements will be received. The reimbursements are deducted from the research and development expenses as the applicable costs are incurred.
 
In connection with purchases of assets, amounts assigned to intangible assets to be used in a particular research and development project that have no alternative future use are charged to research and development costs at the purchase date.
 
Nonrefundable advance payments for goods or services that will be used or rendered for future research and development activities are deferred and amortized over the period that the goods are consumed or the related services are performed.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
NOTE 1 - SIGNIFICANT ACCOUNTING POLICIES (continued):
 
 	l.	Concentration of credit risks and trade receivable	
 
Financial instruments that potentially subject the Company to concentration of credit risk consist principally of bank deposits. The Company deposits these instruments with highly rated financial institutions, mainly in Israeli banks, and, as a matter of policy, limits the amounts of credit exposure to any one financial institution. The Company has not experienced any credit losses in these accounts and does not believe it is exposed to any significant credit risk on these instruments.
 
The Company’s trade receivable represents amounts to be received from Pfizer and the Company’s customers in Israel. The Company does not require Pfizer or any of its Israeli customers to post collateral with respect to receivables. The Company performs periodic credit evaluations of Pfizer’s financial condition and believes there is no significant risk with respect to Pfizer’s payment of the receivables. As all Israeli customers are government entities, the Company believes there is no significant risk with respect to its receivables from such entities.
 
 	m.	Share-based compensation	
 
The Company accounts for employee’s share-based payment awards classified as equity awards using the grant-date fair value method. The fair value of share-based payment transactions is recognized as an expense over the requisite service period, net of estimated forfeitures. The Company estimates forfeitures based on historical experience and anticipated future conditions.
 
The Company elected to recognize compensation cost for an award with only service conditions that has a graded vesting schedule using the accelerated method based on the multiple-option award approach.
 
When stock options are granted as consideration for services provided by consultants and other non-employees, the grant is accounted for based on the fair value of the stock options issued. Options granted is measured on a final basis at the end of the related service period and is recognized over the related service period using the straight-line method.
 
 	n.	Net loss per share	
 
Basic and diluted loss per share (“LPS”) are computed by dividing net loss by the weighted average number of shares of the Company’s Common Stock, par value $0.001 per share (the “Common Stock”) outstanding for each period.
 
Diluted LPS does not include 7,469,088, 7,280,469 and 10,675,304 shares of Common Stock underlying outstanding options , restricted shares of Common Stock and shares issuable upon conversion of the convertible notes (issued in September 2013) for the fiscal years ended December 31, 2011, 2012 and 2013, respectively, because the effect would be anti-dilutive.
 
 	o.	Convertible notes	
 
The convertible notes are accounted for using the guidance provided set forth in FASB Accounting Standards Codification (ASC) 815 requiring that the Company determine whether the embedded conversion option must be separated and accounted for separately. The Company accounts for the convertible notes as a liability, on an aggregated basis, in their entirely.

NOTE 2 - LICENSE AND SUPPLY AGREEMENT
 
On November 30, 2009, Protalix Ltd. and Pfizer entered into the Pfizer Agreement pursuant to which Pfizer was granted an exclusive, worldwide license to develop and commercialize taliglucerase alfa, except in Israel. Under the terms and conditions of the Pfizer Agreement, Protalix Ltd. retained the right to commercialize taliglucerase alfa in Israel. As mentioned in note 1, in June 2013, Pfizer returned the commercialization rights in Brazil to Protalix Ltd. Under the Pfizer Agreement, Pfizer made an upfront payment to Protalix Ltd. of $60.0 million in connection with the execution of the agreement and shortly thereafter paid Protalix Ltd. an additional $5.0 million upon the Company’s filing of a proposed pediatric investigation plan to the Pediatric Committee of the EMA. Protalix Ltd. received a $25.0 million milestone payment in connection with the approval of taliglucerase alfa by the FDA in May 2012. Protalix Ltd. is entitled to 40% of the results (profits or losses) earned on Pfizer’s sales of taliglucerase alfa. Such result (profit or loss) will be calculated while, in addition to other adjustments, taking into account Protalix Ltd.’s cost of goods sold and Pfizer’s commercial expenses, with certain expenses capped or borne solely by one party (“Collaboration Operation”). Of the losses incurred by the Collaboration Operation through December 31, 2011, 40% will be deducted from the cash payments to be paid to the Company as its share in the profits from future years, if any. This deduction will be limited to a certain percentage of any quarterly profit. As of December 31, 2013 and 2012, the Company accrued a liability in respect of these losses equal to approximately $8.0 million and $8.5 million, respectively.
 
The Company has determined that the initial, non-refundable upfront license fee payment of $60.0 million together with the first $5.0 million payment will be recognized on a straight line basis as revenue over the estimated relationship period (approximately $4.6 million per year). The Company has estimated that the relationship period for its arrangement with Pfizer will be approximately 14 years (commencing upon the Company’s receipt of the up-front license payment) based on the Company’s last material patent relating to taliglucerase alfa to expire. The $25.0 million milestone payment received during 2012 in connection with the FDA’s approval of taliglucerase alfa in the United States was considered to be a substantive milestone for purposes of revenue recognition and, accordingly, was recorded as revenue during the period in which the milestone was achieved.
 
The Company’s deliverables under this collaboration include an exclusive license to taliglucerase alfa as an enzyme replacement therapy for the treatment of Gaucher disease, certain research and development services as required under the Pfizer Agreement for taliglucerase alfa and manufacturing of taliglucerase alfa.
 
According to the terms and conditions of the Pfizer Agreement, the Company retained manufacturing rights and sells its products to Pfizer. In addition, Pfizer is required to reimburse the Company for certain costs it incurs in connection with certain development expenses for taliglucerase alfa. In connection with the payments received under the Pfizer Agreement, Protalix Ltd. is obligated to pay certain royalties. See Note 6a.

NOTE 5 - LIABILITY FOR EMPLOYEE RIGHTS UPON RETIREMENT
 
The Israeli Subsidiary is required to make a severance payment upon dismissal of an employee or upon termination of employment in certain circumstances. The severance pay liability to the employees (based upon length of service and the latest monthly salary - one month’s salary for each year employed) is recorded on the Company’s balance sheets under “Liability for employee rights upon retirement.” The liability is recorded as if it were payable at each balance sheet date on an undiscounted basis.
 
The liability is funded in part from the purchase of insurance policies or by the establishment of pension funds with dedicated deposits in the funds. The amounts used to fund these liabilities are included in the Company’s balance sheets under “Funds in respect of employee rights upon retirement.” These policies are the Company’s assets. However, under labor agreements and subject to certain limitations, any policy may be transferred to the ownership of the individual employee for whose benefit the funds were deposited. In the years ended December 31, 2011, 2012 and 2013, the Company deposited approximately $181,000, $177,000 and $194,000, respectively, with insurance companies in connection with its severance payment obligations.
 
In accordance with the current employment agreements with certain employees, the Company makes regular deposits with certain insurance companies for accounts controlled by each applicable employee in order to secure the employee’s rights upon retirement. The Company is fully relieved from any severance pay liability with respect to each such employee after it makes the payments on behalf of the employee. The liability accrued in respect of these employees and the amounts funded, as of the respective agreement dates, are not reflected in the Company’s balance sheets, as the amounts funded are not under the control and management of the Company and the pension or severance pay risks have been irrevocably transferred to the applicable insurance companies (the “Contribution Plans”).
 
The amounts of severance pay expenses were approximately $816,000, $1.0 million and $1.0 million for the years ended December 31, 2011, 2012 and 2013, respectively, of which approximately $641,000, $670,000 and $801,000 in the years ended December 31, 2011, 2012 and 2013, respectively, were in respect of a Contribution Plan. Gain on amounts funded in respect of employee rights upon retirement totaled approximately $14,000, $36,000 and $58,000 for the years ended December 31, 2011, 2012 and 2013, respectively.
 
The Company expects to contribute approximately $1.1 million in the year ending December 31, 2014 to insurance companies in connection with its severance liabilities for its operations for that year, approximately $847,000 of which will be contributed to one or more Contribution Plans.
 
During the five-year period following December 31, 2013, the Company expects to pay future benefits to three employees upon each such employee’s normal retirement age. The Company anticipates that the benefits payable will be immaterial.

NOTE 6 - COMMITMENTS
 
 	a.	Royalty commitments	
 
 	1.	The Company is obligated to pay royalties to the OCS on proceeds from the sale of products developed from research and development activities that were funded, partially, by grants from the OCS. At the time the grants were received, successful development of the related projects was not assured.	
 
In the case of failure of a project that was partly financed as described above, the Company is not obligated to pay any such royalties or repay funding received from the OCS.
 
Under the terms of the funding arrangements with the OCS, royalties of 3% to 6% are payable on the sale of products developed from projects funded by the OCS, which payments shall not exceed, in the aggregate, 100% of the amount of the grant received (dollar linked), plus, commencing upon January 1, 2001, interest at annual rate based on LIBOR. In addition, if the Company receives approval to manufacture products developed with government grants outside the State of Israel, it will be required to pay an increased total amount of royalties (possibly up to 300% of the grant amounts plus interest), depending on the manufacturing volume that is performed outside the State of Israel, and, possibly, an increased royalty rate.
 
Royalty expenses to the OCS are included in the statement of operations as a component of the cost of revenues and were approximately $158,000, $1.5 million and $392,000 during the years ended December 31, 2011, 2012 and 2013, respectively.
 
At December 31, 2013, the maximum royalty amount payable by the Company under these funding arrangements is approximately $26.7 million (without interest, assuming 100% of the funds are payable).
 
 	2.	The Company is a party to certain research and license agreements. Under the agreements, the Company is obligated to pay royalties at varying rates from its future revenues. The aggregate royalties payable under all of the agreements is equal to a varying range of percentages of net sales of licensed products. Royalty expenses under the agreements are included in the statement of operations as a component of the cost of revenues and were approximately $19,000, $674,000 and $80,000 during the years ended December 31, 2011, 2012 and 2013, respectively.	
 
Under each agreement, the Company is also obligated to pay milestone, licensing and other payments to the counterparties of the agreement. The payments under the agreements are for varying amounts and are subject to varying conditions. If all of the contingencies with respect to milestone payments under the research and license agreements are met, the aggregate milestone payments payable would be approximately $0.3 million and would be payable, if at all, as the Company’s projects progress over the course of a number of years. No milestone payments were made during 2011, 2012 and 2013.
 
None of the agreements has a fixed termination date. Subject to earlier termination for other reasons, each agreement terminates after a certain number of years following the first commercial sale of any licensed product under the agreement or after a certain number of years without the initiation of commercial sales of any product under the agreement.

 	3.	On September 18, 2013, the Company completed a private offering of 4.50% convertible notes due 2018. The net proceeds from the offering, including net proceeds from the exercise in full by the initial purchaser of its option to purchase an additional $9.0 million in aggregate principal amount of the Notes, were $66.8 million (net of the initial purchaser’s discount and commission and offering expenses payable by the Company). See also Note 8.	
 
NOTE 8 - CONVERTIBLE NOTES
 
On September 18, 2013, the Company completed a private placement of $69.0 million in aggregate principal amount of Notes, including $9.0 million aggregate principal amount of Notes related to the initial purchaser’s over-allotment option, which was exercised in full. In connection with the completion of the offering, the Company entered into an indenture (the “Indenture”) with The Bank of New York Mellon Trust Company, N.A., as trustee, governing the Notes. The Notes accrue interest at a rate of 4.50% per year, payable semiannually in arrears on March 15 and September 15 of each year, beginning on March 15, 2014. The Notes mature on September 15, 2018.
 
The net proceeds from the offering, including net proceeds from the exercise in full by the initial purchaser of its option to purchase an additional $9.0 million in aggregate principal amount of the Notes, were $66.8 million, after deducting the initial purchaser’s discount and commission and offering expenses payable by the Company. The debt discount and debt issuance costs are deferred and amortized over the convertible notes period (5 years).
 
Holders may convert their Notes at any time prior to the close of business on the business day immediately preceding September 15, 2018. The initial conversion rate for the Notes is 173.6593 shares of the Common Stock for each $1,000 principal amount of Notes (equivalent to an initial conversion price of approximately $5.76 per share of the Common Stock. Upon conversion, the Company will deliver a number of shares of Common Stock, per $1,000 principal amount of Notes, equal to the conversion rate. The conversion rate is subject to adjustment in some events but will not be adjusted for any accrued and unpaid interest.
 
Prior to September 19, 2016, the Company may not redeem the Notes, and no sinking fund is provided for the Notes. On or after September 19, 2016, the Company may redeem for cash all or part of the Notes (except for the notes that the Company is then required to repurchase in connection with a fundamental change, as defined below) if the last reported sale price of the Common Stock has been at least 130% of the conversion price then in effect for at least 20 trading days (whether or not consecutive) during any 30 consecutive trading-day period ending on the trading day immediately preceding the date on which the Company provides the notice of redemption. The redemption price will equal the sum of (i) 100% of the principal amount of the Notes being redeemed, plus (ii) accrued and unpaid interest, including additional interest, if any, to, but excluding, the redemption date, plus (iii) the sum of the present values of each of the remaining scheduled payments of interest that would have been made on the Notes being redeemed had such Notes remained outstanding from the redemption date to the maturity date.

NOTE 9 - FAIR VALUE MEASUREMENT
 
The Company measures fair value and discloses fair value measurements for financial assets and liabilities. Fair value is based on the price that would be received from the sale of an asset, or paid to transfer a liability, in an orderly transaction between market participants at the measurement date.
 
The accounting standard establishes a fair value hierarchy that prioritizes observable and unobservable inputs used to measure fair value into three broad levels, which are described below:
 
Level 1: Quoted prices (unadjusted) in active markets that are accessible at the measurement date for assets or liabilities. The fair value hierarchy gives the highest priority to Level 1 inputs.
 
Level 2: Observable prices that are based on inputs not quoted on active markets, but corroborated by market data.
 
Level 3: Unobservable inputs are used when little or no market data is available. The fair value hierarchy gives the lowest priority to Level 3 inputs.
 
In determining fair value, the Company utilizes valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs to the extent possible and considers counterparty credit risk in its assessment of fair value.
 
The fair value of the financial instruments included in the working capital of the Company is usually identical or close to their carrying value.
 
The fair value of the convertible notes as of December 31, 2013 is approximately $72 million based on level 2 measurement.

The Israeli Subsidiary has an “Approved Enterprise” plan since 2004 and “Benefited Enterprise” plan since 2009. The period of benefits in respect of the main enterprise of the Company has not yet commenced. The period during which the Company is entitled to benefits in connection with the Benefited Enterprise expires in 2021.
 
If the Israeli Subsidiary subsequently pays a dividend out of income derived from the “Approved Enterprise” or “Benefited Enterprise” during the tax exemption period, it will be subject to a tax on the amount distributed, including any company tax on these amounts, at the rate which would have been applicable had such income not been exempted.
 
In addition to the corporate taxes in Israel, the Company might be subject to a withholding tax on the U.S. revenue source portion of the payments made to the Company for its share of Pfizer’s net profits under the Pfizer Agreement. The withholding tax rate is currently 15%.
 
 	b.	Accelerated depreciation	
 
The Israeli Subsidiary is entitled to claim accelerated depreciation, as provided by Israeli law, in the first five years of operation of each asset, in respect of buildings, machinery and equipment used by the Approved Enterprise and the Benefited Enterprise.

NOTE 10 - TAXES ON INCOME (continued):
 	c.	Conditions for entitlement to the benefits	
 
The Israeli Subsidiary’s entitlement to the benefits described above is subject to its fulfilling the conditions stipulated by the law, rules and regulations published thereunder, and the instruments of approval for the specific investment in an approved enterprise. If there is any failure by the Israeli Subsidiary to comply with these conditions, the benefits may be cancelled and the Subsidiary may be required to refund the amount of the benefits, in whole or in part, with interest. The Israeli Subsidiary received a final implementation approval with respect to its “Approved Enterprise” from the Investment Center.
 
 	d.	Amendment of the Law for the Encouragement of Capital Investments, 1959	
 
The Encouragement of Capital Investments Law was amended as part of the Economic Policy Law for the years 2011-2012, which was passed by the Israeli Knesset on December 29, 2010 (the “Capital Investments Law Amendment”).
 
The Capital Investments Law Amendment sets alternative benefit tracks to those currently in effect under the provisions of the Encouragement of Capital Investments Law.
 
The benefits granted to the Benefited Enterprises will be unlimited in time, unlike the benefits granted to special Benefited enterprises, which will be limited for a 10-year period. The benefits shall be granted to companies that will qualify under criteria set in the law; for the most part, those criteria are similar to the criteria that were set in the Encouragement of Capital Investments Law prior to its amendment.
 
Under the transitional provisions of the Encouragement of Capital Investments Law, the Company is entitled to take advantage of the tax benefits available under the Encouragement of Capital Investments Law prior to its amendment until the end of the benefits period, as defined in the Encouragement of Capital Investments Law. The Company will be allowed to set the “year of election” no later than tax year 2012, provided that the minimum qualifying investment was made not later than the end of 2010. On each year during the benefits period, the Company will be able to elect that the Capital Investments Amendment apply to the Company, thereby making the tax rates described above available to the Company. An election to have the Capital Investments Amendment apply is irrecoverable. The Company elected not to have the Capital Investments Amendment apply to the Company.
 
 	4.	The Law for the Encouragement of Industry (Taxation), 1969:	
 
The Israeli Subsidiary is an “industrial company,” as defined under the Law for the Encouragement of Industry (Taxation), 1969 (the “Law for the Encouragement of Industry”). As such, the Israeli Subsidiary is entitled to claim depreciation at increased rates for equipment used in industrial activity, as stipulated by regulations published under Law for the Encouragement of Industry, and has done so.
 
Under the provisions of the Income Tax Regulations “Accelerated Depreciation in respect of Equipment acquired during the Defined Period” (Temporary Orders), industrial companies whose operations are mostly “eligible operations” are entitled to claim accelerated depreciation at a rate of 50% on machinery and equipment acquired from June 1, 2008 to May 31, 2009.
 
 	c.	Tax losses carried forward to future years	
 
As of December 31, 2013, the Company had aggregate net operating loss (NOL) carry-forwards equal to approximately $112.7 million that are available to reduce future taxable income as follows:

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
NOTE 10 - TAXES ON INCOME (continued):
 	1.	The Company	
 
The NOL carry-forward of the Company equal to approximately $15.3 million may be restricted under Section 382 of the Internal Revenue Code (“IRC”). IRC Section 382 applies whenever a corporation with NOL experiences an ownership change. As a result of IRC Section 382, the taxable income for any post change year that may be offset by a pre-change NOL may not exceed the general IRC Section 382 limitation, which is the fair market value of the pre-change entity multiplied by the IRC long-term tax exempt rate.
 
 	2.	Protalix Ltd.	
 
At December 31, 2013, the Israeli Subsidiary had approximately $97.4 million of NOL carry-forwards that are available to reduce future taxable income with no limited period of use.
 
 	d.	Deferred income taxes:	
 
The components of the Company’s net deferred tax assets at December 31, 2012 and 2013 were as follows:
 
 	 	December 31,	 	
(U.S. dollars in thousands)	 	2012	 	 	2013	 	
In respect of:

Valuation allowance	 	 	(31,536	)	 	 	(38,426	)	
 	 	 	-	 	 	 	-	 	

Deferred taxes are computed using the tax rates expected to be in effect when those differences reverse. The Company used tax rates of 39%, 25%, 26.5% and 0%.
 
 	e.	Reconciliation of the theoretical tax expense to actual tax expense	
 
The main reconciling item between the statutory tax rate of the Company and the effective rate is the provision for full valuation allowance in respect of tax benefits from carry forward tax losses due to the uncertainty of the realization of such tax benefits (see above).
 
 	f.	Tax assessments	
 
In accordance with the Income Tax Ordinance, as of December 31, 2013, all of Protalix Ltd.’s tax assessments through tax year 2009 are considered final.
 
A summary of open tax years by major jurisdiction is presented below:
