Item 1.01 Entry into a Material Definitive Agreement

On August 12, 2021, Protalix BioTherapeutics, Inc. (the “Company”) entered into definitive agreements (the “Exchange Agreements”) relating to exchanges (the “Exchanges”) of an aggregate of $54.65 million principal amount of the Company’s outstanding 7.50% Senior Secured Convertible Notes due 2021 (the “Existing Notes”) for an aggregate of $28.75 million principal amount of newly issued 7.50% Senior Secured Convertible Notes due 2024 (the “Exchange Notes”), $25.90 million in cash and accrued and unpaid interest through the cloing date. The Exchange Agreements contain customary representations, warranties and covenants by us together with customary closing conditions. The Exchanges, which will be made in reliance on the exemption from the registration requirements of the Securities Act of 1933, as amended (the “Securities Act”), pursuant to Section 4(a)(2) thereof, is expected to close as soon as practicable, subject to satisfaction of certain closing conditions. Following the closing of the Exchanges, the Company expects that $3.27 million aggregate principal amount of the Existing Notes will remain outstanding. The description of the Exchange Agreements contained in this Current Report on Form 8-K is qualified in its entirety by reference to the complete text of the form of the Exchange Agreement, a copy of which is filed as Exhibit 10.1 and incorporated herein by reference.

The Exchange Notes will be issued pursuant to an Indenture to be entered into between the Company, the guarantors party thereto, The Bank of New York Mellon Trust Company, N.A., as trustee and Wilmington Savings Fund Society, FSB, as collateral agent (the “Indenture”). Like the Existing Notes and at equal priority, the Exchange Notes will be secured by perfected liens on all of the material assets of the Company and its subsidiaries. Interest on the Exchange Notes will be payable semi-annually at a rate of 7.50% per annum. The Exchange Notes mature three years after issuance, unless earlier purchased, converted, exchanged or redeemed, and will be guaranteed by the Company’s subsidiaries.

Holders may require the Company to repurchase their Exchange Notes upon the occurrence of certain events that constitute a fundamental change under the Indenture at a purchase price equal to the principal amount thereof plus accrued and unpaid interest to, but excluding, the fundamental change purchase date.

Holders may convert their Exchange Notes at any time prior to the close of business on the business day immediately preceding the stated maturity date of the Exchange Notes. Upon conversion, the Company may, at its election, deliver shares of the Company’s common stock (“Common Stock”), cash or a combination of shares of Common Stock and cash based on the applicable conversion rate. However, until the Company obtains stockholder approval to issue additional shares of Common Stock upon conversion of the Exchange Notes, the Company will be required to settle at least a portion of its conversion obligation in cash. The Company intends to seek stockholder approval promptly in order to settle conversions of the Exchange Notes in Common Stock.

The initial conversion rate is based on a 32.5% premium to the closing price of the Company’s Common Stock on the NYSE American at the close of trading on August 13, 2021.

The Indenture includes covenants customary for instruments of this type, including, without limitation, restrictions on the Company’s ability to incur additional indebtedness, create liens on its properties, pay dividends and make restricted payments or certain investments, and also requires the Company to apply a portion of the proceeds from certain asset sales or licensing arrangements to redeem the Notes, in each case subject to certain exceptions.

The offer and sale of the Exchange Notes and the shares of Common Stock issuable upon conversion of the Exchange Notes, if any, will not be registered under the Securities Act or any state securities laws, and unless so registered, the Exchange Notes and such shares may not be offered or sold in the United States except pursuant to an exemption from the registration requirements of the Securities Act and applicable state laws.

the Parties Signatory Hereto

Dated as of August 12, 2021

EXCHANGE AGREEMENT dated as of August 12, 2021 (this “Agreement”), by and among Protalix BioTherapeutics, Inc., a Delaware corporation (the “Company”), and the parties signatory hereto (each, a “Purchaser,” and collectively, the “Purchasers”).

BACKGROUND

As of the date hereof, each Purchaser owns and holds an aggregate principal amount of the Company’s 7.50% Senior Secured Convertible Notes due 2021 (the “Existing Notes”) shown opposite such Purchaser’s name under “Principal Amount of Existing Notes” on Schedule I hereto. The Existing Notes have the covenants and terms set forth in the indenture dated as of December 7, 2016, as supplemented by the First Supplemental Indenture, dated July 24, 2017, and the Second Supplemental Indenture, dated November 27, 2017 (the “Existing Indenture”), between the Company, the guarantors party thereto, The Bank of New York Mellon Trust Company, N.A., as trustee (the “Trustee”) and Wilmington Savings Fund Society, FSB, as collateral agent (the “Collateral Agent”). All capitalized terms used herein that are not otherwise defined shall have the meanings ascribed to them in the Existing Indenture.

Each Purchaser desires to exchange with the Company (the “Exchange”) its Existing Notes for (a) the aggregate principal amount of newly issued 7.50% Senior Secured Convertible Notes due 2024 (the “Exchange Notes”) shown opposite such Purchaser’s name under “Principal Amount of Exchange Notes” on Schedule I hereto; (b) cash in the amount shown opposite such Purchaser’s name under “Cash Consideration” on Schedule I hereto (the “Cash Consideration”) and (c) cash in the amount of the accrued and unpaid interest on such Existing Notes through, but excluding, the Closing Date (as defined below) (the “Accrued Interest”), in a transaction exempt from registration under the Securities Act of 1933, as amended (the “Securities Act”), pursuant to the provisions of Section 3(a)(9) thereof.

Each of the Purchasers has irrevocably and unconditionally agreed to consent to the adoption of a third supplemental indenture, in form and substance reasonably acceptable to the Purchasers (the “Third Supplemental Indenture”) to amend the terms of the Existing Indenture to permit the issuance of the Exchange Notes, the incurrence of liens securing the Exchange Notes, the entry by the Company, the guarantors party thereto, the Trustee and the Collateral Agent into the indenture to be dated as of the Closing Date (as defined below) for the Exchange Notes (the “Exchange Notes Indenture”) and that the liens securing the Exchange Notes shall be pari passu with the Existing Notes and Existing Indenture (effective as of the execution of this Agreement).

In consideration of the mutual covenants and agreements contained in this Agreement, the receipt and sufficiency of which are hereby acknowledged, and intending to be legally bound, the Company and the Purchasers, severally but not jointly, hereby agree as follows:

Article I

EXCHANGE

Section 1.1Exchange. The Company agrees to (a) issue to each Purchaser that principal amount of Exchange Notes as set forth on Schedule I hereto opposite such Purchaser’s name and (b) pay to such Purchaser that amount of cash in U.S. dollars representing the sum of the Cash Consideration as set forth on Schedule I hereto opposite such Purchaser’s name and the

Accrued Interest on the Existing Notes of such Purchaser, (the consideration referenced in the foregoing clauses (a) and (b), the “Exchange Consideration”), in exchange for the Existing Notes of such Purchaser having the aggregate principal amount set forth on Schedule I hereto opposite such Purchaser’s name, and each Purchaser, severally and not jointly, agrees to exchange all such Existing Notes for such Exchange Consideration.

Section 1.2Exchange Procedures.

(a)The closing of the Exchange (the “Closing”) will commence upon the satisfaction or waiver of the conditions and obligations of the Company and the Purchasers to consummate the Exchange set forth in Article IV (other than conditions and obligations with respect to the actions that the Company and the Purchasers, respectively, will take at Closing), or such other date and time as the Company and the Purchasers may mutually determine (the “Closing Date”); provided, however, that in the event the Closing does not occur on or prior to September 23, 2021 (the “Outside Date”), this Agreement shall terminate in its entirety and be of no further effect. No later than 10:00 a.m., New York City time, on the Closing Date, each Purchaser shall cause the custodian through which such Purchaser holds its Existing Notes to (i) post a DWAC request to the Trustee to effect the cancellation of the Existing Notes in accordance with the procedures of The Depository Trust Company (“DTC”), and (ii) post a DWAC request to the Trustee for free receipt of the aggregate principal amount of Exchange Notes opposite such Purchaser’s name on Schedule I hereto. The delivery of the Existing Notes by each Purchaser will be complete upon receipt by the Trustee on the Closing Date of a DWAC request through DTC (and the Trustee’s confirmation of such DWAC request) and any other required documents.

(b)On the Closing Date, the Company, or Trustee at the Company’s direction, will (i) cause the Exchange Notes to be credited to the DTC accounts identified by each Purchaser (as specified on its signature page hereof) against delivery of the Existing Notes, as set forth on Schedule I hereof and (ii) cause the payment of the Cash Consideration and the Accrued Interest by wire transfer of immediately available funds to the accounts previously provided in writing by each Purchaser.

(c)The Purchasers shall cease to own the Existing Notes exchanged pursuant to Section 1.1 hereto as of the crediting of the Exchange Notes to the DTC accounts identified by the Purchasers and the payment of the Cash Consideration and the Accrued Interest by wire transfer as provided in clause (b) above, and the Company shall be entitled to instruct the appropriate parties to immediately thereafter cancel the Existing Notes on the books and records of the Company.

Protalix BioTherapeutics Announces Private Note Exchange

CARMIEL, Israel, August 13, 2021 /PRNewswire/Protalix BioTherapeutics, Inc. (NYSE American:PLX) (TASE:PLX), a biopharmaceutical company focused on the development, production and commercialization of recombinant therapeutic proteins produced by its proprietary ProCellEx^® plant cell-based protein expression system, today announced the entry into definitive agreements (the “Exchange Agreements”) relating to exchanges (the “Exchanges”) of an aggregate of $54.65 million principal amount of the Company’s outstanding 7.50% Senior Secured Convertible Notes due 2021 (the “Existing Notes”) for an aggregate of $28.75 million principal amount of newly issued 7.50% Senior Secured Convertible Notes due 2024 (the “Exchange Notes”), $25.90 million in cash and accrued and unpaid interest through the closing date. The Exchanges are expected to close as soon as practicable, subject to satisfaction of certain closing conditions. Following the closing of the Exchanges, the Company expects that $3.27 million aggregate principal amount of the Existing Notes will remain outstanding.

“The exchange of the notes underscores Protalix’s commitment to addressing our capital structure while continuing development of our pegunigalsidase alfa program and our early pipeline,” said Dror Bashan, Protalix’s President and Chief Executive Officer. “We believe that the participation of so many of our institutional note holders, including funds managed by Highbridge Capital Management, LLC, UBS O’Connor LLC, Citigroup Global Markets, Whitebox Advisors, and Tulip Capital, is a telling vote of confidence in Protalix.”

Like the Existing Notes and at equal priority, the Exchange Notes will be secured by perfected liens on all of the material assets of the Company and its subsidiaries. Interest on the Exchange Notes will be payable semi-annually at a rate of 7.50% per annum. The Exchange Notes will mature three years after issuance, unless earlier purchased, converted, exchanged or redeemed, and will be guaranteed by the Company’s subsidiaries.

Holders may require the Company to repurchase their Exchange Notes upon the occurrence of certain events that constitute a fundamental change under the indenture that will govern the Exchange Notes (the “Indenture”) at a purchase price equal to the principal amount thereof plus accrued and unpaid interest to, but excluding, the fundamental change purchase date.

Holders may convert their Exchange Notes at any time prior to the close of business on the business day immediately preceding the stated maturity date of the Exchange Notes. Upon conversion, the Company may, at its election, deliver shares of the Company’s common stock (“Common Stock”), cash or a combination of shares of Common Stock and cash based on the applicable conversion rate. However, until the Company obtains stockholder approval to issue additional shares of Common Stock upon conversion of the Exchange Notes, the Company will be required to settle at least a portion of its conversion obligation in cash. The Company intends to seek stockholder approval promptly in order to be able to settle conversions of the Exchange Notes in Common Stock.

The initial conversion rate will be based on a 32.5% premium to the closing price of the Common Stock on the NYSE American at the close of trading on August 13, 2021.

The Indenture includes covenants customary for instruments of this type, including, without limitation, restrictions on the Company’s ability to incur additional indebtedness, create liens on its properties, pay dividends and make restricted payments or certain investments, and also requires the Company to apply a portion of the proceeds from certain asset sales or licensing arrangements to repay the Exchange Notes, in each case subject to certain exceptions.

“This exchange transaction allows us to continue to advance our lead drug candidate, PRX-102, towards approval and to progress our early stage pipeline candidates,” said Eyal Rubin, Protalix’s Sr. Vice President and Chief Financial Officer.

This announcement is neither an offer to sell nor a solicitation of an offer to buy any of these securities and shall not constitute an offer, solicitation, or sale in any jurisdiction in which such offer, solicitation, or sale is unlawful. The offer and sale of the Exchange Notes and the shares of Common Stock issuable upon conversion of the Exchange Notes, if any, will not be registered under the Securities Act of 1933 or any state securities laws, and unless so registered, the Exchange Notes and such shares may not be offered or sold in the United States except pursuant to an exemption from the registration requirements of the Securities Act of 1933 and applicable state laws.

About Protalix BioTherapeutics, Inc.

Protalix is a biopharmaceutical company focused on the development and commercialization of recombinant therapeutic proteins expressed through its proprietary plant cell-based protein expression system, ProCellEx. Protalix was the first company to gain U.S. Food and Drug Administration (FDA) approval of a protein produced through a plant cell-based in suspension expression system. Protalix’s unique expression system represents a new method for developing recombinant proteins in an industrial-scale manner.

Protalix’s first product manufactured by ProCellEx, taliglucerase alfa, was approved by the FDA in May 2012 and, subsequently, by the regulatory authorities of other countries. Protalix has licensed to Pfizer Inc. the worldwide development and commercialization rights for taliglucerase alfa, excluding Brazil, where Protalix retains full rights.

Protalix’s development pipeline consists of proprietary versions of recombinant therapeutic proteins that target established pharmaceutical markets, including the following product candidates: pegunigalsidase alfa, a modified stabilized version of the recombinant human α–Galactosidase-A protein for the treatment of Fabry disease; alidornase alfa, or PRX-110, for the treatment of various human respiratory diseases or conditions; PRX-115, a plant cell-expressed recombinant PEGylated uricase for the treatment of refractory gout; PRX-119, a plant cell-expressed long action DNase I for the treatment of NETs-related diseases; and others. Protalix has partnered with Chiesi Farmaceutici S.p.A., both in the United States and outside the United States, for the development and commercialization of pegunigalsidase alfa, and with SarcoMed USA, Inc. for the worldwide development and commercialization of PRX-110 for use in the

treatment of any human respiratory disease or condition including, but not limited to, sarcoidosis, pulmonary fibrosis, and other related diseases via inhaled delivery.
