#### NOTE 1 - SIGNIFICANT ACCOUNTING POLICIES
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;a. **General** 

Protalix BioTherapeutics, Inc. and its wholly-owned subsidiary, Protalix Ltd. (collectively, the "Company"), are commercial stage biopharmaceutical companies focused on the discovery, development, production, and commercialization of innovative therapeutics for rare diseases with significant unmet needs. ProCellEx<sup>®</sup>, the Company's proprietary plant cell-based protein expression system ("ProCellEx"), represents a new method for developing recombinant proteins in an industrial-scale manner.

The Company's commercial product portfolio consists of two enzyme replacement therapies (ERTs):

● Elelyso <sup>®</sup> (taliglucerase alfa) for the treatment of adult patients and children four years of age and older with Gaucher disease. This product is approved in the United States, Brazil, and Israel, as well as many other jurisdictions.

● Elfabrio <sup>®</sup> (pegunigalsidase alfa) for the treatment of adult patients with a confirmed diagnosis of Fabry disease. This product is approved in the United States, the European Union, and other jurisdictions with a 1 mg/kg every-two-weeks (E2W) dosage. In March 2026, Elfabrio was approved for a 2 mg/kg every-four-weeks (E4W) dosage in the European Union.

In addition, the Company's product pipeline currently includes, among other candidates:

● PRX 115, the Company's plant cell-expressed recombinant PEGylated uricase (urate oxidase) – a chemically modified enzyme to treat uncontrolled gout; and

● PRX 119, the Company's plant cell-expressed PEGylated recombinant human DNase I product candidate for long and customized systemic circulation in the bloodstream for NETs-related diseases (neutrophil extracellular traps).

The Company is committed to leveraging its record of success as the Company develops treatments for rare and orphan diseases. In addition, the Company is continuously further developing and enhancing its ProCellEx technology. Accordingly, the Company is turning its focus to new, early-stage product candidates that treat indications for which there are high unmet needs in terms of efficacy and safety, including renal diseases. The Company currently intends to focus on treatments that will address both genetic and non-genetic diseases. The Company plans to use its ProCellEx platform and PEGylation capabilities, as well as other modalities such as small molecules and antibodies, to take advantage of highly innovative opportunities. The Company is also exploring novel platform technologies. Consistent with its strategy, the Company continuously evaluates potential strategic marketing partnerships, as well as collaboration programs with biotechnology and pharmaceutical companies and academic research institutions. Except with respect to Elfabrio and Elelyso, the Company holds the worldwide commercialization rights to its other proprietary development candidates.

Consistent with its strategy, the Company continuously evaluates potential strategic marketing partnerships as well as collaboration programs with biotechnology and pharmaceutical companies and academic research institutions.

Because the Company's operations are conducted in the State of Israel, the Company's business and operations face risks related to the military, economic, political, and geopolitical conditions in Israel. Since October 2023, Israel has suffered from missile and other similar attacks and has been engaged in military activity on a number of fronts, including with the Hamas and other terrorist groups in the Gaza Strip, with Hezbollah in Lebanon, in Iran, with the Houthis terrorist group that controls parts of Yemen, and others, and both civilian and military targets in Israel have been attacked. In June 2025 and again in February 2026, Israel and the United States conducted strikes against Iranian military and nuclear infrastructure, both of which involved Iranian counterattacks as well as Hezbollah attacks on Israel. Ceasefires have been declared in connection with all of these military actions. Despite the ceasefires, the situation remains volatile, with the potential for renewed escalation involving Iran or other terrorist organizations. The Company's facilities are deemed an "essential enterprise," which means it operates or can be operated for the purposes of state defense or public security or

for the maintenance of essential supplies or services, allowing the Company to maintain operations during emergencies. The Company has elected to store manufactured drug substance in multiple locations, both within and outside of Israel, to mitigate the risk of loss. It is currently not possible to predict whether or not such ceasefires will be maintained, or the duration or severity of the above conflicts or the effects of such conflicts, or any of them, on the Company's operations. As of the issuance of these financial statements, the impacts of the military actions described above have not had a material adverse effect on the Company's business, results of operations, and financial condition.

The Company expects to continue to incur significant expenditures in the near future due to research and developments efforts with respect to its product candidates. The Company believes that its cash and cash equivalents and short-term bank deposits as of March 31, 2026 are sufficient to satisfy the Company's capital needs for at least 12 months from the date that these financial statements are issued.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;b. **Basis of presentation** 

The accompanying unaudited condensed consolidated financial statements of the Company have been prepared in accordance with generally accepted accounting principles in the United States ("GAAP") for interim financial information. Accordingly, they do not include all of the information and notes required by GAAP for annual financial statements. In the opinion of management, all adjustments (of a normal recurring nature) considered necessary for a fair statement of the results for the interim periods presented have been included. Operating results for the interim period are not necessarily indicative of the results that may be expected for the full year.

These unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements in the Annual Report on Form 10-K for the year ended December 31, 2025, filed by the Company with the U.S. Securities and Exchange Commission (the "Commission") on March 18, 2026. The comparative balance sheet at December 31, 2025 has been derived from the audited financial statements at that date. There have been no material changes in our significant accounting policies as described in our consolidated financial statements for the year ended December 31, 2025.

Basic earnings (loss) per share is calculated by dividing net income (loss) by the weighted average number of shares of common stock, par value $0.001 per share ("Common Stock"), outstanding for each period.

In computing diluted earnings per share, basic earnings per share are adjusted to take into account the potential dilution that could occur upon: (i) the exercise of options and non-vested restricted stock granted under employee stock compensation plans using the treasury stock method; and (ii) the exercise of warrants using the treasury stock method.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;d.  **New** accounting pronouncements** 

*Recently issued accounting pronouncements, not yet adopted*

In November 2024, the FASB issued ASU 2024-03 "Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses," which requires disclosure about the types of costs and expenses included in certain expense captions presented on the income statement. ASU 2024-03 is effective for fiscal years beginning after December 15, 2026, and interim periods within fiscal years beginning after December 15, 2027, with early adoption permitted, and may be applied either prospectively or retrospectively. The Company is currently evaluating this guidance to determine the impact it may have on its consolidated financial statements disclosures.

In December 2025, the FASB issued ASU 2025-10 "Government Grants (Topic 832)" to establish authoritative guidance on the accounting for government grants received by business entities. This update is effective beginning with the

[**Table of Contents**](#TOC)

#### NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
(Unaudited)

Company's 2029 fiscal year annual reporting period, with early adoption permitted. The Company is currently evaluating the impact that the adoption of this standard will have on its consolidated financial statements.

In December 2025, the FASB issued ASU 2025-11 to amend the guidance in "Interim Reporting" (Topic 270). The update provides clarifications intended to improve the consistency and usability of interim disclosure requirements, including a comprehensive listing of required interim disclosures and a new disclosure principle for reporting material events occurring after the most recent annual period. The amendments do not change the underlying objectives of interim reporting but are designed to enhance clarity in application. The ASU is effective for fiscal years beginning after December 15, 2027, and interim periods within those fiscal years. The Company is currently evaluating the effects that ASU 2025-11 will have on its interim consolidated financial statements and related disclosures.

#### NOTE 2 - INVENTORIES
Inventories at March 31, 2026 and December 31, 2025 consisted of the following:

| Work in progress | 9083 | 9375 |
| Finished goods | 15384 | 10374 |
| Total inventory | $30474 | $25729 |

---

#### NOTE 3 – FAIR VALUE MEASUREMENT
The Company 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 identical or close to their carrying value.

**Item 2. Management's Discussion and Analysis of Financial Condition and Results of Operations**

**CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING STATEMENTSAND RISK FACTORS SUMMARY**

*You should read the following discussion and analysis of our financial condition and results of operations together with our financial statements and the consolidated financial statements and the related notes included elsewhere in this Form 10-Q and in our Annual Report on Form 10-K for the year ended December 31, 2025. 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 within the meanings of Section 27A of the Securities Act of 1933, as amended, or the Securities Act, and Section 21E of the Securities Exchange Act of 1934, as amended, or the Exchange Act, including statements regarding expectations, beliefs, intentions or strategies for the future. When used in this report, the terms "anticipate," "believe," "estimate," "expect," "can," "continue," "could," "intend," "may," "plan," "potential," "predict," "project," "should," "will," "would" and words or phrases of similar import, as they relate to our company, our subsidiary or our management, are intended to identify forward-looking statements. We intend that all forward-looking statements be subject to the safe-harbor provisions of the Private Securities Litigation Reform Act of 1995. These forward-looking statements are only predictions and reflect our views as of the date they are made with respect to future events and financial performance, and we undertake no obligation to update or revise, nor do we have a policy of updating or revising, any forward-looking statement to reflect events or circumstances after the date on which the statement is made or to reflect the occurrence of unanticipated events, except as may be required under applicable law. Forward-looking statements are subject to many risks and uncertainties that could cause our actual results to differ materially from any future results expressed or implied by the forward-looking statements as a result of several factors, including those set forth in this Quarterly Report on Form 10-Q.*

Examples of the risks and uncertainties include, but are not limited to, the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;●risks related to the commercialization of Elfabrio<sup>®</sup> (pegunigalsidase alfa-iwxj), our approved product for the treatment of adult patients with Fabry disease;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;●risks relating to Elfabrio's market acceptance, competition, reimbursement, and regulatory actions, including as a result of the boxed warning contained in the approval received from the U.S. Food and Drug Administration, or FDA, for the product;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;●risks related to the regulatory approval and commercial success of our other product and product candidates, if approved;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;●risks related to our expectations with respect to the projected market of our products and product candidates;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;●failure or delay in the commencement or completion of our preclinical studies and clinical trials, which may be caused by several factors, including: slower than expected rates of patient recruitment; unforeseen safety issues; determination of dosing issues; lack of effectiveness during clinical trials; inability to satisfactorily demonstrate non-inferiority to approved therapies; inability or unwillingness of medical investigators and institutional review boards to follow our clinical protocols; and/or inability to monitor patients adequately during or after treatment;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;●the risk that the results of the clinical trials of our product candidates will not support the applicable claims of safety or efficacy and that our product candidates will not have the desired effects or will be associated with undesirable side effects or other unexpected characteristics;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;●the possible disruption of our operations due to the regional conflict in Iran and the military actions between Israel and Iran, the Hamas terrorist organization located in the Gaza Strip, Hezbollah, the Houthis terrorist group that controls parts of Yemen, and others, including as a result of the disruption of the operations of certain regulatory authorities and of certain of our suppliers, collaborative partners, licensees, clinical trial sites, distributors and customers, and the risk that the current hostilities will result in increased regional conflict;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;●delays in the approval or potential rejection of any applications we file with the FDA, European Medicines Agency, or EMA, or other health regulatory authorities for our other product candidates, and other risks relating to the review process;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;●risks associated with global conditions and developments such as new or increased tariffs, new or changed trade restrictions, supply chain challenges, the inflationary environment and tight labor market, and instability in the banking industry, which may adversely impact our business, operations, and ability to raise additional financing if and as required and on terms acceptable to us;

[**Table of Contents**](#TOC)

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;●risks related to any transactions we may effect in the public or private equity or debt markets to raise capital to finance future research and development activities, general and administrative expenses, and working capital;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;●risks relating to our evaluation and pursuit of strategic partnerships;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;●risks relating to our ability to manage our relationship with our collaborators, distributors, and partners, including, but not limited to, Pfizer Inc., or Pfizer, and Chiesi Farmaceutici S.p.A., or Chiesi;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;●risks related to the amount and sufficiency of our cash, cash equivalents, and short-term bank deposits;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;●risks relating to changes to interim, top-line, or preliminary data from clinical trials that we announce or publish;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;●risks relating to the compliance by Fundação Oswaldo Cruz, or Fiocruz, an arm of the Brazilian Ministry of Health, or the Brazilian MoH, with its purchase obligations under the Supply and Technology Transfer Agreement that we entered into with Fiocruz in June 2013, or the Brazil Agreement, which may have a material adverse effect on us and may result in our termination of such agreement;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;●risk of significant lawsuits, including stockholder litigation, which is common in the life sciences sector;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;●our dependence on performance by third-party providers of services and supplies, including without limitation, clinical trial services;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;●the inherent risks and uncertainties in developing drug platforms and products of the type we are developing;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;●the impact of development of competing therapies and/or technologies by other companies;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;●risks related to our supply of drug products to Pfizer;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;●potential product liability risks, and risks of securing adequate levels of related insurance coverage;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;●the possibility of infringing a third-party's patents or other intellectual property rights and the uncertainty of obtaining patents covering our products and processes and successfully enforcing our intellectual property rights against third-parties; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;●risks relating to changes in healthcare laws, rules, and regulations in the United States or elsewhere.

Given these uncertainties, you should not place undue reliance on these forward-looking statements. 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 preliminary findings for such clinical trials. Even if favorable testing data is generated from clinical trials of a drug product, the FDA or foreign regulatory authorities may not accept or approve a marketing application filed by a pharmaceutical or biotechnology company for the drug product.

**Our Business**

Protalix BioTherapeutics, Inc. and its wholly-owned subsidiary, Protalix Ltd., are commercial stage biopharmaceutical companies focused on the discovery, development, production, and commercialization of innovative therapeutics for rare diseases with significant unmet needs. ProCellEx<sup>®</sup>, our proprietary plant cell-based protein expression system, represents a new method for developing recombinant proteins in an industrial-scale manner.

Currently, our commercial products are both enzyme replacement therapies (ERTs):

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;●Elelyso<sup>®</sup> (taliglucerase alfa) for the treatment of adult patients and children four years of age and older with Gaucher disease. This product is approved in the United States, Brazil and Israel, as well as many other jurisdictions.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;●Elfabrio<sup>®</sup> (pegunigalsidase alfa) for the treatment of adult patients with a confirmed diagnosis of Fabry disease. This product is approved in the United States, the European Union and other jurisdictions with a 1 mg/kg every-two-weeks (E2W) dosage. Additionally, in March 2026, Elfabrio was approved for a 2 mg/kg every-four-weeks (E4W) dosage in the European Union.

[**Table of Contents**](#TOC)

We are committed to leveraging our track record of success as we progress with the development of treatments for rare and orphan diseases. In addition, we continuously work on the further development and enhancement of our ProCellEx technology. Accordingly, we are turning our focus to new, early-stage product candidates that treat indications for which there are high unmet needs in terms of efficacy and safety, including renal diseases. Treatments of interest are likely to address both genetic and non-genetic diseases. We intend to use our ProCellEx platform and PEGylation capabilities, as well as other modalities such as small molecules and antibodies, to take advantage of highly innovative opportunities. We are also exploring novel platform technologies.

Our product pipeline currently includes, among other candidates:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;●PRX 115, a recombinant PEGylated uricase (urate oxidase) – a chemically modified enzyme to treat uncontrolled gout; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;●PRX 119, a PEGylated recombinant human DNase I product candidate for long and customized systemic circulation in the bloodstream for NETs-related diseases (neutrophil extracellular traps).

Our proprietary ProCellEx platform is being used to manufacture both our approved and marketed products as well as PRX-115 and PRX-119.

Given ongoing military actions in the Middle East, and the missile and other strikes within Israel, we have elected to store manufactured drug substance in multiple locations, both within and outside of Israel, to mitigate the risk of loss. Our facilities are deemed an "essential enterprise" which means they operate or can be operated for the purposes of state defense or public security or for the maintenance of essential supplies or services, allowing us to maintain operations during emergencies. To date, the impact of the military actions have not had a material adverse effect on our operations.

*Recent Company Developments*

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;●On March 5, 2026, the EC approved, in the EU, the 2 mg/kg E4W dosing regimen for pegunigalsidase alfa in Fabry disease adult patients stable with an ERT treatment. The approval is the result of an appeal submitted after a negative opinion issued in October 2025.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;●On March 31, 2026, we received a $25.0 million milestone payment from Chiesi in connection with the approval by the EC of the 2 mg/kg E4W dosing regimen for pegunigalsidase alfa in the EU.

*Commercialization of Approved Products*

*Elelyso – Pfizer*

We licensed to Pfizer the global rights to market and sell Elelyso in all markets, excluding Brazil, pursuant to the Amended Pfizer Agreement. Pursuant to the Amended Pfizer Agreement, we agreed to sell drug substance to Pfizer for the production of Elelyso for a fixed cost, subject to certain terms and conditions, through 2030. Any failure to comply with our supply commitments may subject us to substantial financial penalties. The Amended Pfizer Agreement includes customary provisions regarding cooperation for regulatory matters, patent enforcement, termination, indemnification and insurance requirements. We retain distribution rights to taliglucerase alfa in Brazil.

Our sales of Elelyso to Pfizer are made at a fixed price directly to Pfizer who maintains product in inventory, and we recognize revenue from those sales upon delivery. The timing of such sales does not directly reflect patient demand and, on a period-to-period basis, there may be variations in the orders placed by Pfizer resulting in variability in our period-to-period results. There may be periods during which no orders are placed by Pfizer, whether as a result of inventory de-stocking or other factors.

*Alfataliglicerase – Fundação Oswaldo Cruz (Fiocruz)*

Elelyso, marketed as BioManguinhos alfataliglicerase in Brazil, is commercialized in Brazil through the Brazil Agreement with Fiocruz which became effective in January 2014. Gaucher patients in Brazil are entitled to receive ERT paid for by the Brazilian MoH. The Brazilian MoH clinical treatment guidelines (PCDT) state that BioManguinhos alfataliglicerase is the therapy of choice for newly diagnosed patients. BioManguinhos alfataliglicerase is currently estimated to be used by approximately 25% of Gaucher patients in Brazil.

The Brazil Agreement provides for a staged technology transfer that 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-

[**Table of Contents**](#TOC)

quality, and cost-effective supply of BioManguinhos alfataliglicerase. Fiocruz has not satisfied certain purchase commitments under the Brazil Agreement. We continue to sell BioManguinhos alfataliglicerase for a fixed price through purchase orders and we continue to discuss with Fiocruz potential steps to maximize sales of BioManguinhos alfataliglicerase to the Brazilian MoH.

Our sales of BioManguinhos alfataliglicerase to Fiocruz are made at a fixed price directly to Fiocruz which maintains product in inventory, and we recognize revenue from those sales upon delivery. The timing of such sales does not directly reflect patient demand and, on a period-to-period basis, there may be variations in the orders placed by Fiocruz resulting in variability in our period-to-period results. There may be periods during which no orders are placed by Fiocruz, whether as a result of inventory de-stocking or other factors.

*Elfabrio (pegunigalsidase alfa/PRX-102) – Chiesi Farmaceutici*

Elfabrio is commercialized worldwide by Chiesi under the Chiesi Agreements. Under the Chiesi Ex-US Agreement, we granted to Chiesi an exclusive license for all markets outside of the United States to commercialize pegunigalsidase alfa. At execution of the Chiesi Ex-US Agreement, Chiesi made an upfront, non-refundable, non-creditable payment to Protalix Ltd. of $25.0 million, followed by additional payments of $25.0 million to cover development costs in the aggregate. Protalix Ltd. currently remains eligible to receive additional payments of up to a maximum of $270.0 million, in the aggregate and including the $25.0 million currently payable, subject to the satisfaction of certain regulatory and commercial milestones. Protalix Ltd. agreed to manufacture all of the pegunigalsidase alfa needed for all purposes under the agreement, subject to certain exceptions, and Chiesi agreed to purchase the pegunigalsidase alfa from Protalix Ltd., subject to certain terms and conditions. Chiesi is required to make payments to Protalix Ltd. ranging from 15% to 35% of its net sales under the Chiesi Ex-US Agreement, depending on the amount of annual sales, subject to certain terms and conditions, as consideration for product supply. The Chiesi Ex-US Agreement shall remain in effect until the later of (i) the expiration of the last enforceable Protalix patent right thereunder or (ii) the 15<sup>th</sup> anniversary of the launch of sales of pegunigalsidase alfa on a country-by-country basis, subject to certain terms and conditions, unless earlier terminated in accordance with the terms and conditions thereof.

Under the Chiesi US Agreement we granted to Chiesi the exclusive license to develop and commercialize pegunigalsidase alfa in the United States. Protalix Ltd. received from Chiesi an upfront, non-refundable, non-creditable payment of $25.0 million from Chiesi and additional payments of $20.0 million to cover development costs. To date, we have received the complete amount of such development costs, and, following the approval of Elfabrio by the FDA, we received a milestone payment equal to $20.0 million. Protalix Ltd. currently remains eligible to receive additional payments of up to a maximum of $740.0 million, in the aggregate, subject to the satisfaction of certain regulatory and commercial milestones. Chiesi is required to make payments to Protalix Ltd. ranging from 15% to 40% of its net sales under the Chiesi US Agreement, depending on the amount of annual sales, subject to certain terms and conditions, as consideration for product supply. The Chiesi US Agreement shall remain in effect until the later of (i) the expiration of the last enforceable Protalix patent right thereunder or (ii) the 15<sup>th</sup> anniversary of the launch in the US, unless earlier terminated in accordance with the terms and conditions thereof.

We manufacture Elfabrio drug substance and, after the fill\finish process is complete, we sell the resulting drug product to Chiesi under both agreements. Operationally, Chiesi conducts its own internal commercial forecasting to guide inventory needs. To date, Chiesi has placed bulk orders for Elfabrio. As a result, the orders we receive from Chiesi may not be timed in relation to Chiesi's pace of patient acquisition and retention. Accordingly, our sales of Elfabrio to Chiesi may not reflect patient demand for Elfabrio as we sell the fulfilled orders to Chiesi's inventory. In addition, on a period-to-period basis, there may be variations in the orders placed by Chiesi resulting in variability in our period-to-period results as we, in turn, recognize revenues from sales of Elfabrio upon delivery of the drug product to Chiesi. There may be periods during which no orders are placed by Chiesi, whether as a result of inventory de-stocking or other factors. We do not anticipate that these Chiesi ordering patterns will change until the demand characteristics for Elfabrio stabilize, the launch of Elfabrio matures and Elfabrio's share of the market for Fabry disease treatment grows both inside the US and outside the US.

*Intellectual Property*

A key element of our overall strategy is to establish a broad portfolio of patents to protect our proprietary technology, proprietary product and product candidates and their methods of use. As of March 31, 2026, we hold a broad portfolio of 15 patent families consisting of approximately 68 patents in Europe, the United States, Israel, and additional countries worldwide, as well as approximately 38 pending patent applications.

*Research & Development*

We are committed to leveraging our track record of success as we develop treatments for rare and orphan diseases. In addition, we are continuously further developing and enhancing our ProCellEx technology. Accordingly, we are turning our focus to new, early-stage

[**Table of Contents**](#TOC)

product candidates that treat indications for which there are high unmet needs in terms of efficacy and safety, including renal diseases. We currently intend that our treatments will address both genetic and non-genetic diseases. We currently intend to use our ProCellEx platform and PEGylation/chemical capabilities, as well as other modalities such as small molecules and antibodies, to take advantage of highly innovative opportunities. We are also exploring novel platform technologies to expand our pipeline.

In addition, we continuously work on the further development of our ProCellEx plant cell expression technology and bioreactor system.

**Critical Accounting Policies**

Our significant accounting policies are more fully described in Note 1 to our consolidated financial statements appearing in this Quarterly Report. There have been no material changes to our critical accounting policies since we filed our Annual Report on Form 10-K for the year ended December 31, 2025.

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.

***Three months ended March 31, 2026 compared to the three months ended March 31, 2025***

*Revenues from Selling Goods*

Revenues from selling goods consisted of the following:

---

| | | | |
|:---|:---|:---|:---|
| | **Three Months Ended March 31,**  | **Three Months Ended March 31,**  | |
| <br>*(U.S. dollars in thousands)* | **2025** | **2026** | <br>**2026 vs. 2025** |
| Pfizer | $6979 | $1452 | $(5527) |
| Fiocruz | 3016 | 2454 | (562) |
| Chiesi | - | 3513 | 3513 |
| Total revenues from selling goods | 9995 | 7419 | (2576) |

---

[**Table of Contents**](#TOC)

Revenues from selling goods for the three months ended March 31, 2026 reflects a decrease of 26% compared to revenues from selling goods for the three months ended March 31, 2025. The decrease in sales to Pfizer resulted primarily from a timing shift in Pfizer's purchases for the three months ended March 31, 2026 compared to increased purchases of Elelyso by Pfizer in the three months ended March 31, 2025 to address unexpected manufacturing issues at Pfizer. The decrease in sales to Fiocruz (Brazil) are due to the timing of deliveries. The total decrease in revenues from selling goods for the period was partially offset by an increase in sales to Chiesi.

*Revenues from License and R&D Services*

Revenues from license and R&D services were as follows:

---

| | | | |
|:---|:---|:---|:---|
| | **Three Months Ended March 31,**  | **Three Months Ended March 31,**  | |
| <br>*(U.S. dollars in thousands)* | **2025** | **2026** | <br>**2026 vs. 2025** |
| Revenues from license and R&D services | $118 | $26331 | $26213 |

---

The increase in revenues from license and R&D services for the three months ended March 31, 2026 compared to license and R&D services for the three months ended March 31, 2025 resulted from the $25.0 million milestone we received from Chiesi in connection with the approval of the E4W dosage in the EU. Revenues from license and R&D services are comprised primarily of revenues we recognized in connection with the Chiesi Agreements. We expect to generate minimal revenues from license and R&D services now that we have completed the clinical development of Elfabrio.

*Cost of Revenues*

Cost of revenues were as follows:

---

| | | | |
|:---|:---|:---|:---|
| | **Three Months Ended March 31,**  | **Three Months Ended March 31,**  | |
| <br>*(U.S. dollars in thousands)* | **2025** | **2026** | <br>**2026 vs. 2025** |
| Cost of goods sold | $8180 | $4127 | $(4053) |

---

Cost of revenues for the three months ended March 31, 2026 represents a decrease of 50% from cost of revenues for the three months ended March 31, 2025. The decrease resulted primarily from a decrease in sales to Pfizer and Fiocruz (Brazil) which was partially offset by an increase in sales to Chiesi.

*Research and Development Expenses*

Research and development expenses were as follows:

---

| | | | |
|:---|:---|:---|:---|
| | **Three Months Ended March 31,**  | **Three Months Ended March 31,**  | |
| <br>*(U.S. dollars in thousands)* | **2025** | **2026** | <br>**2026 vs. 2025** |
| Salary and related expenses | $1894 | $2762 | $868 |
| Subcontractor-related expenses | 805 | 1435 | 630 |
| Materials-related expenses | 216 | 417 | 201 |
| Other expenses | 560 | 812 | 252 |
| Total research and development expenses | 3475 | 5426 | 1951 |

---

Total increase in research and developments expenses for the three months ended March 31, 2026 represents an increase of 56% compared to research and developments expenses for the three months ended March 31, 2025. The increase in research and development expenses resulted primarily from preparations for and the initiation of our RELEASE study.

We expect to continue to incur significant, increasing research and development expenses as we progress with the RELEASE study and commence more advanced stages of preclinical and clinical trials for certain of our other product candidates.

[**Table of Contents**](#TOC)

*Selling, General, and Administrative Expenses*

Selling, general, and administrative expenses were as follows:

---

| | | | |
|:---|:---|:---|:---|
| | **Three Months Ended March 31,**  | **Three Months Ended March 31,**  | |
| <br>*(U.S. dollars in thousands)* | **2025** | **2026** | <br>**2026 vs. 2025** |
| SG&A expenses | $2603 | $3051 | $448 |

---

Selling, general, and administrative expenses for the three months ended March 31, 2026 represents an increase of 17% compared to selling, general, and administrative expenses for the three months ended March 31, 2025. The increase resulted primarily from an increase of $0.4 million in salary and related expenses.

*Financial Income (Expenses), Net*

Financial expenses, net were as follows:

---

| | | | |
|:---|:---|:---|:---|
| | **Three Months Ended March 31,**  | **Three Months Ended March 31,**  | |
| <br>*(U.S. dollars in thousands)* | **2025** | **2026** | <br>**2026 vs. 2025** |
| Financial expenses (income), net | $(413) | $5 | $418 |

---

The difference in financial expenses, net for the three months ended March 31, 2026 compared to financial income, net for the three months ended March 31, 2025 resulted primarily from $0.3 million in recorded expenses due to exchange rate fluctuations between the US Dollar and the New Israel Shekel, and a decrease of $0.1 million in interest income.

*Income Taxes (Tax Benefit)*

Income taxes (tax benefit) were as follows:

---

| | | | |
|:---|:---|:---|:---|
| | **Three Months Ended March 31,**  | **Three Months Ended March 31,**  | |
| <br>*(U.S. dollars in thousands)* | **2025** | **2026** | <br>**2026 vs. 2025** |
| Income taxes (tax benefit) | $(113) | $2824 | $2937 |

---

We recorded tax expenses of approximately $2.8 million for the three months ended March 31, 2026 and a tax benefit of approximately $(0.1) million for the three months ended March 31, 2025. The tax expenses resulted primarily from taxes on income mainly derived from global intangible low-taxed income (GILTI) resulting primarily from limitations under IRC Section 174. On July 4, 2025, tax reform legislation was enacted in the United States through the passage of H.R.1, The One Big Beautiful Bill Act, which includes significant corporate tax changes, including a restoration of the current deductibility of domestic research expenditures beginning in 2025 under Section 174A, with transition options for previously capitalized amounts. Foreign research expenditures continue to require capitalization subject to the mandatory 15-year amortization period under existing IRC Section 174. We implemented the permitted transition options.

**Liquidity and Capital Resources**

Our sources of liquidity include our cash balances and short-term bank deposits. At March 31, 2026, we had $51.1 million in cash and cash equivalents and short-term bank deposits. We have primarily financed our operations through sales proceeds, equity and debt financings, business collaborations, and grants funding.

On February 27, 2023, we entered into an At The Market Offering Agreement, or the Sales Agreement, with H.C. Wainwright & Co., LLC, as the sales agent, or the Agent, which provided for the sale, from time to time through the Agent, shares of Common Stock having an aggregate offering price of up to $20.0 million. On March 17, 2025, the Sales Agreement was amended to increase the aggregate gross sales price of shares of Common Stock available for offer and sale under the Sales Agreement by $20.0 million. We have no obligation to sell any shares of Common Stock under the Sales Agreement, and may at any time suspend sales under the Sales Agreement or terminate the Sales Agreement in accordance with its terms. The Agent is entitled to a commission of up to 3.0% of the aggregate gross proceeds from the shares of Common Stock sold under the Sales Agreement. During the three months ended March 31, 2025, we sold, in the aggregate 1,325,179 shares of Common Stock under the Sales Agreement generating gross proceeds equal to approximately $3.0 million (issuance costs were $0.1 million). We did not make any sales during the three months ended March 31, 2026. As of March 31, 2026, approximately $15.7 million in shares of Common Stock remain available to be sold under the Sales Agreement.

[**Table of Contents**](#TOC)

During the three months ended March 31, 2025, we issued 908,000 shares of Common Stock, in the aggregate, in connection with the exercise of warrants issued in 2020 generating proceeds equal to approximately $2.1 million from such exercises. The remaining warrants expired on March 11, 2025. Accordingly, as of March 12, 2025, no warrants remain outstanding.

We believe that our cash and cash equivalents and short-term bank deposits are sufficient to satisfy our capital needs for at least 12 months from the date this report is issued.

**Cash Flows**

Our cash flows for each of the three months ended March 31, 2026 and 2025 were as follows:

---

| | | | |
|:---|:---|:---|:---|
| | **Three Months Ended March 31,**  | **Three Months Ended March 31,**  | |
| <br>*(U.S. dollars in thousands)* | **2025** | **2026** | <br>**2026 vs. 2025** |
| Net cash provided by (used in) operating activities | $(5058) | $22025 | $27083 |
| Net cash provided by (used in) investing activities | $(312) | $4223 | $4535 |
| Net cash provided by financing activities | $5076 | $150 | $(4926) |

---

Net cash provided by operations was $22.0 million for the three months ended March 31, 2026. The net income for the three months ended March 31, 2026 of $18.3 million was increased by a $6.4 million decrease in accounts receivable-trade and other assets, $0.5 million in share-based compensation, $0.2 million in financial expenses, net, $0.4 million in depreciation and a $0.8 million increase in accounts payable and accruals, and was offset a $4.7 million increase in inventories.

Net cash provided by investing activities was $4.2 million for the three months ended March 31, 2026 and consisted primarily of $10.0 million short-term deposit withdrawal partially offset by a $5.0 million investment in bank deposits and $0.8 million in the purchase of property and equipment.

Net cash provided by financing activities was $0.2 million for the three months ended March 31, 2026 and resulted from the exercise of options.

Net cash used in operations was $5.1 million for the three months ended March 31, 2025. The net loss for the three months ended March 31, 2025 of $3.6 million was increased by a $1.3 million decrease in accounts payable and accruals, a $2.3 million increase in accounts receivable-trade and other assets and $0.4 million in financial income, net and was offset by $0.5 million in share-based compensation, a $1.7 million decrease in inventories, and $0.3 million in depreciation.

Net cash used in investing activities for the three months ended March 31, 2025 was $0.3 million and consisted primarily of the purchase of property and equipment.

Net cash provided by financing activities for the three months ended March 31, 2025 was $5.1 million and consisted of $2.9 million in proceeds from the issuance of Common Stock under the Sales Agreement, net and $2.2 million from the exercise of warrants and options.

**Future Funding Requirements** 

Since our inception, we have incurred significant research and development expenditures which have not been offset by revenues. We have not generated significant revenues from sales of Elelyso or Elfabrio. We have generated operating losses from our continuing operations since our inception although the revenues generated in the years ended December 31, 2023 and 2024, and in the three months ended March 31, 2026, exceeded our expenditures for the same periods.

As we increase our research and developments efforts with respect to our current and future product candidates, we expect to continue to incur significant expenditures. We cannot anticipate the costs or the timing of the occurrence of such costs. Although we expect the revenues generated from the sales of Elfabrio and Elelyso will increase, such revenues may not be sufficient to fund the expenditures. To the extent we need to obtain additional financing in excess of such anticipated revenues, it may be difficult for us to do so given the volatility of the price of our Common Stock. Our material cash needs for the next 24 months will include, among other expenses, (i) costs of preclinical and clinical trials, in particular those of our RELEASE study, (ii) employee salaries, (iii) payments for rent and operation of our manufacturing facilities, (iv) fees to our consultants and legal advisors, patent advisors and fees for service providers in connection with our research and development efforts and (v) expansion of additional manufacturing space within our current facility and (vi) tax payments. We believe that the funds currently available to us are sufficient to satisfy our capital needs for at least 12 months from the date this report is issued.

[**Table of Contents**](#TOC)

As discussed above, we may be required to raise additional capital to develop our product candidates and continue research and development activities. Our ability to raise capital, and the amounts of necessary capital, will depend on many other factors, including:

● the duration and cost of discovery and preclinical development and laboratory testing and clinical trials for our product candidates;

● Chiesi's progress in commercializing Elfabrio;

● our progress in commercializing BioManguinhos alfataliglicerase in Brazil;

● 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; and

● the costs associated with any litigation claims.

We expect to finance our future cash needs through sales of Elfabrio and Elelyso, corporate collaborations, licensing or similar arrangements, public or private equity offerings and/or debt financings. We currently do not have any commitments for future external funding, except with respect to the milestone payments that may become payable under the Chiesi Agreements.

**Effects of Currency Fluctuations** 

Currency fluctuations could affect us through increased or decreased acquisition costs for certain goods and services and salaries expenses. For the three months ended March 31, 2026 the currency fluctuations were immaterial.

**Off-Balance Sheet Arrangements** 

We have no off-balance sheet arrangements as of each of March 31, 2026 and December 31, 2025.

**Item 3. 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 U.S. dollar. Most of our revenues and more than 50% of our expenses and capital expenditures are and were 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 41% 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 loss 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:

---

| | | | |
|:---|:---|:---|:---|
|  | **Three Months Ended**  | **Three Months Ended**  | **Year Ended** |
|  | **March 31,**  | **March 31,**  | **December 31,**  |
|  | **2026** | **2025** | **2025** |
| Average rate for period | 3.121 | 3.613 | 3.452 |
| Rate at period-end | 3.165 | 3.718 | 3.190 |

---

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.

**Item 4. 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 Quarterly Report on Form 10-Q. The 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 Quarterly Report on Form 10-Q, 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.

Based on the evaluation, our Chief Executive Officer and Chief Financial Officer have concluded that, as of the end of the period covered by this Quarterly Report on Form 10-Q, 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 relating 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.

**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.

**Changes in Internal Control over Financial Reporting**

There were no changes in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) that occurred during the quarter ended March 31, 2026 that have materially affected, or that are reasonably likely to materially affect, our internal control over financial reporting.

## Exhibit 10.1

**Exhibit 10.1**

#### AMENDED & RESTATED EMPLOYMENT AGREEMENT
This AMENDED AND RESTATED EMPLOYMENT AGREEMENT (this "**Agreement**") is made effective as of May 12, 2026 (the "**Effective Date**"), by and between Protalix Ltd., a company organized under the laws of the State of Israel (the "**Company**") and Yaron Naos, a resident of the State of Israel (the "**Executive**") (each of the Company and Executive shall be referred to herein, as a "**Party**" and collectively, the "**Parties**").

**WHEREAS**, the Executive, who was promoted to Sr. Vice President & Chief Executive Officer, is currently an employee of the Company and of its parent company, Protalix BioTherapeutics, Inc. (the "**Parent Company**"), and was a party to that certain Employment Agreement between the Company and the Executive, effective as of September 8, 2004 which agreement is superseded in its entirety by this Agreement; and

**WHEREAS**, the Company and the Executive desire to restate the terms and conditions of the Executive's employment by the Company as hereinafter set forth.

**NOW, THEREFORE**, based on the representations contained herein and in consideration of the mutual premises and covenants set forth herein, the Company and the Executive hereby agree that the terms and conditions of the Executive's employment are hereby amended and restated in their entirety to read as follows:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1. **Employment .** 

1.1.The Executive's duties and responsibilities shall continue to be those duties and responsibilities customarily performed by a Sr. Vice President & Chief Operating Officer of a pharmaceutical company that is publicly-traded in the U.S. stock markets, as may be determined from time to time by the Company's Chief Executive Officer of the Company ("**CEO**"). The Executive will continue to report to the CEO.

1.2.The Executive shall continue to be employed on a full-time basis and to devote his full and undivided attention and full working time to the business and affairs of the Company and the fulfillment of his duties and responsibilities under this Agreement. Unless otherwise approved in advance and in writing by the CEO, other than as stipulated in this Section 1.2, during the term of this Agreement, the Executive shall not be engaged in any other employment nor engage in any other business activity or render any business services, with or without compensation, for any other person or entity. The Executive shall notify the Company immediately of any event or circumstance which may hinder the performance of his obligations hereunder or result in the Executive having a conflict of interest with his Position.

1.3.It is agreed between the Parties that the position that the Executive holds within the Company is a management position, which demands a special level of loyalty and accordingly the Work Hours and Rest Law (1951) shall not apply to the Executive's employment by the Company and this Agreement. The Executive further acknowledges and agrees that his duties and responsibilities may entail irregular work hours and extensive traveling in Israel and abroad, for which he is adequately rewarded by the compensation provided in this Agreement. The Parties confirm that this is a personal services contract and that the relationship between the Parties shall not be subject to any general or special collective bargaining agreement or any custom or practice of the Company in respect of any of its other employees or contractors.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2. **Salary and Employee Benefits .** 

In full consideration of the Executive's continued employment hereunder, commencing as of the Commencement Date (unless otherwise expressly provided in this Section 2), the Executive shall be entitled to the following payments and benefits, it being understood and agreed that any salary-based benefits shall be calculated exclusively on the basis of the base salary (without consideration to any other benefit):

2.1.<u>Salary</u>. The Company shall continue to pay the Executive a gross salary of NIS 70,000 per month (the "**Salary**"). The Salary shall be payable monthly in arrears and shall be paid to the Executive in accordance with the Company's policy.

2.2.<u>Bonus</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2.2.1The Executive shall be entitled to an annual bonus based on multiples of the Executive's base monthly Salary, subject to the approval of the Board of Directors of the Company or its Compensation Committee (collectively, the "**Board**"), and at its sole discretion. The determination of the Board (and any other organ approval required under applicable law) shall be made following the end of each calendar year during the term hereof and the bonus shall be payable, if applicable, with the next salary following the publication of the Company's annual financial report. The Board shall determine the bonus on the basis of annual objectives which shall include both measurable and strategic parameters (in such ratios as shall be approved by the Board), to be agreed in advance with the Executive on an annual basis (the "**Objectives**"). The Board's (and any other organ's approval required under applicable law) decision regarding the foregoing bonus payment shall be based on the Board's determinations, in its discretion, that the Executive achieved 80% or more of the Objectives (the "**Percentage Achievement**"). The amount of the bonus is anticipated to fall within the following range: (i) for achievement of 80% of the Objectives, a bonus in an amount equal to four (4) monthly Salaries; (ii) for achievement of 100% of the Objectives, a bonus in an amount equal to five (5) monthly Salaries; and (iii) for achievement of 120% of the Objectives, a bonus in an amount equal to six (6) monthly Salaries, which will also be the maximum amount.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2.2.2.The Board shall be entitled to grant, at any time, and notwithstanding the foregoing, a discretionary bonus to the Executive, based on significant achievements.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2.2.3Without derogating the foregoing, in the event of Triggered COC (as defined below), Employee shall be entitled to receive a one-time bonus in the amount of US $400,000 ("**COC Bonus**"); <u>provided</u>, <u>however</u>, that (i) the COC Bonus is inclusive of any termination notice and other applicable amounts stipulated under this Agreement; and (ii) the COC Bonus is inclusive of any milestone achieved following the consummation of such change of control.

**For the purpose hereof, Triggered COC shall mean: Change in ownership or control of the Parent Company effected through the direct acquisition by any person or related group of persons (other than an acquisition from or by the Parent Company or by a Parent Company-sponsored employee benefit plan or by a person that directly or indirectly controls, is controlled by, or is under common control with, the Parent Company) of beneficial ownership (within the meaning of Rule 13d-3 promulgated under the U.S. Securities Exchange Act of 1934) of securities possessing more than fifty percent (50%) of the total combined voting power of the Parent Company's outstanding securities pursuant to an agreement which was initiated by the Board and was led by an investment bank on its behalf.**

------

It is agreed that the definition of Triggered COC is applicable only to this Agreement and not to the Plan (as defined below).

2.3.<u>Equity Incentives</u>. The Executive shall continue to be entitled, from time to time at the discretion of the Board to equity incentive awards commensurate with the Position.

2.4.<u>Indemnification; D&O Insurance</u>. The Executive shall remain entitled to the same indemnification terms and conditions granted to all other officers and directors of the Company and the Parent Company and, accordingly, each of the Company and the Parent Company and the Executive shall, prior to the Commencement Date, enter into an indemnification and release agreement in the form granted to all other officers and directors of the Company and the Parent Company. In addition, each of the Parent Company and the Company shall maintain Directors' and Officers' insurance policy or policies, providing coverage that is no less favorable for the Executive than the coverage then being provided to any other present or former executive officer or director of the Company or the Parent Company that shall apply to the other executive officers and directors of the Company.

2.5.<u>Managers Insurance Policy ("Bituach Menahalim") and/or Pension Fund ("Keren Pensya")</u>. According to the Executive's choice, the Company shall effect a Manager's Insurance Policy or Pension Fund or a combination thereof, (the "**Policy**") in the name of the Executive, and shall pay a sum of 8.33% of the Salary for severance pay. The Company shall deduct 6% from the Salary to be paid as benefits (Tagmulim) on behalf of the Executive towards such Policy. The Company's contribution for the Policy shall be 6.5% of the Salary as employer's share for benefits (Tagmulim).

In the event that the Executive shall elect to be insured in a Manager's Insurance Policy or a provident fund which is not a Pension Fund - the Company's contributions for benefits (Tagmulim) shall include payment for disability insurance in an amount which will ensure 75% of the Salary; <u>provided</u>, <u>however</u>, that in any event the contributions of the Company for benefits shall be equal to at least 5% of the Salary, and the total cost of the Company for disability insurance and benefits shall not exceed 7.5% of the Salary.

The Parties hereby declare and agree that the pension arrangement in accordance with this clause constitutes a "beneficial arrangement" for the purpose of the Extension Order (Combined Version) for Mandatory Pension under the Collective Agreements Law, 5717-1957 (the "**Pension Extension Order**"), and the Company shall not be under any obligation to provide any pension arrangement as provided in the Pension Extension Order other than as provided in this Section.

Without derogating from the generality of the aforesaid, all payments made by the Company to the Policy shall be in lieu of severance pay due to the Executive or his heirs from the Company, and the Company shall not have any additional or other obligations to pay the Executive severance payments, and the Executive hereby consents to this arrangement in accordance with Section 14 of the Severance Pay Law 5723-1963 and the *"General Approval Regarding Payments by Employers to a Pension Fund and Insurance Fund in Lieu of Severance Pay"* (the "**General Approval**"), a copy of which is attached to this Agreement as **Exhibit A**, and the provisions of the General Approval shall apply to the Executive and this Agreement.

For avoidance of doubt, as of the date indicated herein, the General Approval has not yet been updated to reflect the percentages of contributions/deductions indicated above. In the event of

------

discrepancy between the updated General Approval and the percentages stated herein, the updated General Approval shall prevail.

The Company hereby waives any entitlement and/or right for reimbursement with respect to the severance compensation and acknowledges, that upon termination of the Executive's employment in the Company, including inter alia, in the event of the Executive's resignation, the Company shall release the severance compensation and shall transfer the severance compensation to the Executive, except in the event that: (i) the Company has terminated the Executive's employment due to circumstances under which his entitlement for severance payment is denied pursuant to Articles 16 or 17 of the Severance Law; or (ii) the Executive has already withdrawn funds from the Policy and not because of "EIROA MEZAKE" according to Section 2(b) of the General Approval.

2.6.<u>Vocational Studies</u>. The Company shall continue to maintain a "Keren Hishtalmut" Fund for the benefit of the Executive (the "**Fund**"). The Company shall continue to contribute to such Fund an amount equal to 7.5% of the Salary and the Executive shall contribute to the Fund an amount equal to 2.5% of the Salary. The Executive hereby instructs the Company to transfer to the Fund the Executive's contribution from the Salary. Upon termination of this Agreement by either Party, other than termination by the Company for Cause, the Company shall assign and transfer to the Executive the ownership in the Fund.

2.7.<u>Vacation</u>. The Executive shall continue to be entitled to annual paid vacation of 29 working days. Consistent with Company employment policies, the Executive must take vacation for seven (7) consecutive calendar days in each work year. Vacation days not used by the Executive may be accumulated for the next three (3) years of employment; <u>provided</u>, that if the Executive does not take seven (7) consecutive vacation days in any work year, the Executive will only be able to accumulate vacation days from such work year for up to two years. In any event, the Executive may not accumulate a number of vacation days that exceeds the numbers of vacation days to which the Executive is entitled over a three- (3-) year period, in the aggregate. The Executive shall coordinate vacation days in advance with the CEO; <u>provided</u>, <u>however</u>, the Company shall be entitled to set the Executive's vacation days, in its discretion. Vacation days shall not be redeemable for cash by the Executive until termination of the employment relationship, in accordance with applicable law and Company policies, as may be updated from time to time. If the employment begins or ends in the middle of the working year, the Executive's entitlement to vacation days will be increased proportionally. All vacation days that exceed the maximum number of days that may be accumulated by the Executive in accordance with this Agreement or otherwise under the Company's employment policies will be canceled by the Company, and for the avoidance of doubt, will not be redeemable for cash by the Executive until termination of the employment relationship.

2.8.<u>Sick Leave</u>. The Executive shall be entitled to fully paid sick leave pursuant to the Sick Pay Law (1976).

2.9.<u>Annual Recreation Allowance (Dme'i Havra'a)</u>. The Executive shall be entitled to annual recreation allowance according to applicable law.
