Item 1.01. Entry into a Material Definitive Agreement

On June 18, 2013, Protalix Ltd. (“Protalix”), a wholly-owned subsidiary of Protalix BioTherapeutics, Inc. (the “Company”), entered into a Supply and Technology Transfer Agreement with Fundação Oswaldo Cruz, commonly referred to as Fiocruz, an arm of the Brazilian Ministry of Health for UPLYSO™ (alfa-taliglicerase), the Company’s proprietary enzyme replacement therapy for the treatment of Gaucher disease.

The technology transfer is expected to take place during a seven-year term 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 UPLYSO. Under the agreement, Fiocruz has committed to purchase at least approximately US$40 million worth of UPLYSO during the first two years of the agreement. In subsequent years, Fiocruz is required to purchase at least approximately US$40 million worth of UPLYSO per year. Additionally, the Company is not required to complete the final stage of the technology transfer until Fiocruz purchases at least approximately US$280 million worth of UPLYSO. The 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 the Brazilian National Health Surveillance Agency (ANVISA) to manufacture UPLYSO in its facility in Brazil, the agreement will enter into the final term and will remain in effect until the Company’s last patent in Brazil expires. During such period, Fiocruz will be the sole provider of UPLYSO in Brazil and shall pay the Company a single-digit royalty on net sales.

The agreement will become effective after the parties receive approval of the agreement by the Brazilian National Institute of Industrial Property, which is expected to occur within approximately a month of the signature date of the agreement. The agreement may be terminated by the Company in the event of certain breaches of representations and warranties by Fiocruz; certain material defaults by Fiocruz in the performance of its obligations under the agreement; any privatization of Fiocruz or acquisition of Fiocruz by a competitor of the Company; any failure by Fiocruz to make payments under the agreement, subject to the right to cure; certain changes of control of Fiocruz; if Fiocruz fails to meet certain specified purchase requirements; in certain bankruptcy-related situations; and others. The agreement may be terminated by Fiocruz in the event of certain breaches of representations and warranties by the Company; certain material defaults by the Company in the performance of its obligations under the agreement; if, due to changes in Brazilian law, Fiocruz is unable to comply with the agreement; and if prGCD, in its finished dosage form, is recalled by ANVISA and the U.S. Food and Drug Administration. Upon any termination of the agreement, all licenses and rights granted to Fiocruz under the agreement shall terminate.

The Company and Fiocruz agreed to indemnify each other for certain losses under the agreement.

UPLYSO is marketed as ELELYSO^TM in the United States and Israel.

To facilitate the arrangement with Fiocruz, the Company's commercialization partner for UPLYSO, Pfizer Inc., amended its exclusive license and supply agreement with the Company. The amendment provides for the transfer of the commercialization and other rights to UPLYSO in Brazil back to the Company.

As consideration for the transfer of the commercialization and supply agreements, the Company agreed to pay Pfizer a maximum amount of approximately $12.5 million from its net profits (as defined in the agreement) per year. Pfizer has also agreed to perform certain transitional services on the Company’s behalf in connection with the supply of UPLYSO to Fiocruz and the technology transfer.

The Company will pay a fee equal to 5% of the net proceeds generated in Brazil to its agent for services provided in assisting the Company complete the agreement pursuant to an agency agreement between the Company and the agent. The agency agreement will remain in effect with respect to the supply and technology transfer agreement or any other similar agreement until the termination of the applicable agreement.
