     Except where the context otherwise requires, the terms, “we,” “us,” “our” or “the Company,” refer to the business of Protalix BioTherapeutics, Inc. and its consolidated subsidiaries, and “Protalix” or “Protalix Ltd.” refers to the business of Protalix Ltd., our wholly-owned subsidiary and sole operating unit.
CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING STATEMENTS
     The statements set forth under the captions “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and “Risk Factors,” and other statements included elsewhere in this Quarterly Report on Form 10-Q, which are not historical, constitute “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended, including statements regarding expectations, beliefs, intentions or strategies for the future. When used in this report, the terms “anticipate,” “believe,” “estimate,” “expect” and “intend” and words or phrases of similar import, as they relate to us or our subsidiaries 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. 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.
     Examples of the risks and uncertainties include, but are not limited to, the following:
    the inherent risks and uncertainties in developing drug platforms and products of the type we are developing;
 
    delays in our preparation and filing of applications for regulatory approval;
 
    delays in the approval or the potential rejection of any applications we file with the U.S. Food and Drug Administration, or the FDA, or other regulatory authorities, including the New Drug Application (NDA) we have filed with the FDA for taliglucerase alfa;
 
    any lack of progress of our research and development (including the results of clinical trials we are conducting);
 
    obtaining on a timely basis sufficient patient enrollment in our clinical trials;
 
    the impact of development of competing therapies and/or technologies by other companies;
 
    our ability to obtain additional financing required to fund our research programs;
 
    the risk that we will not be able to develop a successful sales and marketing organization in a timely manner, if at all;
 
    our ability to establish and maintain strategic license, collaboration and distribution arrangements and to manage our relationship with Pfizer Inc., Teva Ltd. or with any other collaborator, distributor or partner;
 
    potential product liability risks and risks of securing adequate levels of product liability and clinical trial insurance coverage;
 
    the availability of reimbursement to patients from health care payors for any of our product candidates, if approved;
 
    the possibility of infringing a third party’s patents or other intellectual property rights;
 
    the uncertainty of obtaining patents covering our products and processes and in successfully enforcing our intellectual property rights against third parties; and
 
    the possible disruption of our operations due to terrorist activities and armed conflict, including as a result of the disruption of the operations of regulatory authorities, our subsidiaries, our manufacturing facilities and our customers, suppliers, distributors, collaborative partners, licensees and clinical trial sites.
     In addition, 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 by clinical trials of a drug product, the FDA might not accept or approve an NDA filed by a pharmaceutical or biotechnology company for the drug product. These and other risks and uncertainties are detailed in our Annual Report on Form 10-K for the year ended December 31, 2009, Section 1A, under the heading “Risk Factors” and are described from time to time in the reports we file with the Securities and Exchange Commission. 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.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)
NOTE 1 — SIGNIFICANT ACCOUNTING POLICIES
     a. General
          1. Operation
Protalix BioTherapeutics, Inc. and its wholly-owned subsidiary, Protalix Ltd. (“Protalix Ltd.,” and collectively with Protalix BioTherapeutics, Inc., the “Company”), are biopharmaceutical companies focused on the development and commercialization of recombinant therapeutic proteins based on the Company’s proprietary ProCellExtm protein expression system (“ProCellEx”). In September 2009, the Company formed another wholly-owned subsidiary under the laws of the Netherlands in connection with the European Medicines Agency, or EMEA, application process in Europe. The Company’s lead product development candidate is taliglucerase alfa for the treatment of Gaucher disease, which the Company is developing using its ProCellEx protein expression system.
In September 2009, the Company successfully completed its phase III pivotal trial of taliglucerase alfa. In July 2010, the U.S. Food and Drug Administration (“FDA”) notified the Company that it had accepted the Company’s new drug application (NDA) for taliglucerase alfa for the treatment of Gaucher disease and that it granted to taliglucerase alfa a Prescription Drug User Fee Act (PDUFA) action date of February 25, 2011. In addition to its phase III clinical trial, the Company initiated a clinical study in December 2008 to evaluate the safety and efficacy of switching Gaucher patients currently treated under the current standard of care to treatment with taliglucerase alfa. This switchover-study is not a prerequisite for the marketing approval of taliglucerase alfa.
The Company was in the development stage from its inception until November 2009 (see b below).
On November 30, 2009, Protalix Ltd. and Pfizer Inc. (“Pfizer”) entered into an Exclusive License and Supply Agreement (the “Pfizer Agreement”) pursuant to which Protalix Ltd. granted Pfizer 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.
In addition to taliglucerase alfa, the Company is developing an innovative product pipeline using the Company’s ProCellEx protein expression system. The Company’s product pipeline currently includes, among other candidates, therapeutic protein candidates for the treatment of Fabry disease, a rare, genetic lysosomal disorder in humans, an acetylcholinesterase enzyme-based therapy for biodefense and pesticide toxicity treatments, antiTNF, a plant cell expressed recombinant fusion protein made from the soluble form of the human TNF receptor (TNFR) which is being developed as a treatment of certain immune diseases such as rheumatoid arthritis, juvenile idiopathic arthritis and others, and additional undisclosed therapeutic proteins, all of which are currently being evaluated in animal studies. In March 2010, the Company initiated a phase I clinical trial of PRX-105, the Company’s plant cell expressed pegylated recombinant acetylcholinesterase product candidate for biodefense indications. In June 2010, the Company completed the phase I clinical trial of PRX-105.

(Unaudited)
NOTE 1 — SIGNIFICANT ACCOUNTING POLICIES (Continued):
Successful completion of the Company’s development program and its transition to normal operations is dependent upon obtaining necessary regulatory approvals from the FDA prior to selling its products within the United States, and foreign regulatory approvals must be obtained to sell its products internationally. There can be no assurance that the Company will receive regulatory approval of any of its product candidates, and a substantial amount of time may pass before the Company achieves a level of sales adequate to support the Company’s operations, if at all. The Company will also incur substantial expenditures in connection with the regulatory approval process for each of its product candidates during the developmental period. Obtaining marketing approval will be directly dependent on the Company’s ability to implement the necessary regulatory steps required to obtain marketing approval in the United States and in other countries. The Company cannot predict the outcome of these activities.
          2. Subsequent Events
The Company has evaluated events through the date of issuance of the financial statements. See Note 3.
     b. General 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 and Article 10 of Regulation S-X under the Securities Exchange Act of 1934. Accordingly, they do not include all of the information and notes required by GAAP for complete 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. Prior to December 2009, the Company was a development stage company as defined under the guidance for Development Stage Enterprises. The Company has determined that, as of November 30, 2009, it is no longer a development stage company.
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, 2009, filed by the Company with the Securities and Exchange Commission. The comparative balance sheet at December 31, 2009 has been derived from the audited financial statements at that date, but does not include all of the information and notes required under GAAP for complete financial statements.
     c. 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 $.001 per share (the “Common Stock”), outstanding for each period.
Shares of restricted Common Stock and the shares of Common Stock underlying outstanding options of the Company were not included in the calculation of diluted LPS because the effect would be anti-dilutive.
Diluted LPS does not include options and restricted shares of Common Stock of the Company in the amount of 11,482,322 and 7,604,195 shares of Common Stock for the six months ended June 30, 2009 and 2010, respectively, and 11,540,215 and 7,930,824 shares of Common Stock for the three months ended June 30, 2009 and 2010, respectively.

NOTE 1 — SIGNIFICANT ACCOUNTING POLICIES (Continued):
  d.   Newly Issued Accounting Pronouncements
 
      In October 2009, the Financial Accounting Standards Board issued an Accounting Standards Update to ASC 605, ASU No. 2009-13, “Multiple Deliverable Revenue Arrangements” (“ASU 2009-13”). ASU 2009-13 provides guidance on whether multiple deliverables in a revenue arrangement exist, how the arrangement should be separated, and how the consideration should be allocated. Pursuant to ASU 2009-13, when vendor specific objective evidence or third party evidence for deliverables in an arrangement cannot be determined, a best estimate of the selling price is required to separate deliverables and allocate arrangement consideration, using the relative selling price method. In addition, the residual method of allocating arrangement consideration is no longer permitted under ASU 2009-13.
 
      ASU 2009-13 is effective for revenue arrangements entered into or materially modified in fiscal years beginning on or after June 15, 2010. The Company is currently evaluating the potential impact of ASU 2009-13 on its consolidated financial position, results of operations and cash flows.
NOTE 2 — STOCK TRANSACTIONS
  a.   During the six months ended June 30, 2010, the Company issued a total of 39,900 shares of Common Stock in connection with the exercise of a total of 54,205 options by certain employees of the Company. The Company received aggregate cash proceeds equal to approximately $27 in connection with such exercises, and 20,312 of the options were exercised on a “net exercise” basis.
 
  b.   On February 7, 2010, the Company’s Board of Directors approved the grant of options to purchase 160,000 shares of Common Stock to a new executive officer of the Company with an exercise price equal to $6.81 per share. The options vest over a four-year period, with the first 25% to vest on the first anniversary of the date of the grant and the remaining 75% in equal tranches on a quarterly basis for three years thereafter. The options are exercisable over a 10-year period commencing on the date of grant. The Company estimated the fair value of the options on the date of grant using the Black-Scholes option-pricing model to be approximately $740,000 based on the following weighted average assumptions: dividend yield of 0% for all years; expected volatility of 76.02%; risk-free interest rates of 2.96%; and expected life of six years.
 
  c.   In February 2010, the Company’s Board of Directors approved the grant of options to purchase 1,016,000 shares of Common Stock, in the aggregate, to certain officers and employees of the Company with an exercise price equal to $6.90 per share. The options vest quarterly over three years, commencing after the FDA’s approval of taliglucerase alfa, if at all. The options are exercisable over a 10-year period commencing on the date of grant. The Company estimated the fair value of the options on the date of grant using the Black-Scholes option-pricing model to be approximately $5.7 million, based on the following weighted average assumptions: dividend yield of 0% for all years; expected volatility of 75.74%; risk-free interest rates of 3.69%; and expected life of 10 years. The Company will start charging these expenses following the FDA’s approval of taliglucerase alfa, if at all.
NOTE 3 — SUBSEQUENT EVENTS
During July 2010, the Company issued a total of approximately 1,000 shares of Common Stock in connection with the exercise of options to purchase approximately 1,000 shares of Common Stock by certain employees of the Company. The aggregate cash proceeds in connection with the exercise of these options are equal to $0.4.

Item 2. 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 financial statements and the consolidated financial statements and the related notes included elsewhere in this Form 10-Q and our Annual Report on Form 10-K for the year ended December 31, 2009. 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 our Annual Report on Form 10-K for the year ended December 31, 2009 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 ProCellExTM protein expression system, or ProCellEx. Using our ProCellEx system, we are developing a pipeline of proprietary and biosimilar or “generic” versions of recombinant therapeutic proteins based on our plant cell-based expression technology that 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 our ProCellEx protein expression system 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.
     Our lead product development candidate is taliglucerase alfa for the treatment of Gaucher disease, which we are developing using our ProCellEx protein expression system. Gaucher disease is a rare and serious lysosomal storage disorder with severe and debilitating symptoms. Taliglucerase alfa is our proprietary recombinant form of glucocerebrosidase (GCD), an enzyme naturally found in human cells that is mutated or deficient in patients with Gaucher disease. In July 2007, we reached an agreement with the U.S. Food and Drug Administration, or the FDA, on the final design of our pivotal phase III clinical trial of taliglucerase alfa, through the FDA’s special protocol assessment (SPA) process. The phase III clinical trial was completed in September 2009 and, on October 15, 2009, we announced positive top-line results from the trial. On December 9, 2009, we filed our New Drug Application (NDA) for taliglucerase alfa, and in January 2010 the FDA requested additional data regarding the Chemistry, Manufacturing and Controls (CMC) section of our NDA. We provided the requested data in April 2010 and in July 2010 we received notification from the FDA that it had accepted the filing of our NDA and assigned a PDUFA date of February 25, 2011 to taliglucerase alfa.
     In March 2010, the Israeli Ministry of Health completed a successful audit of our manufacturing facilities in Carmiel, Israel. The audit was performed as part of the Ministry of Health’s evaluation of our manufacturing process for taliglucerase alfa.
     In addition to our recently completed phase III clinical trial, during the third quarter of 2008, we initiated a double-blind, follow-on extension study as part of the trial. We also initiated a home care treatment program for patients enrolled in the extension study and in December 2008, we initiated a clinical study evaluating the safety and efficacy of switching Gaucher patients currently treated under the current standard of care to treatment with taliglucerase alfa. The current standard of care for Gaucher patients is enzyme replacement therapy with CerezymeTM which is produced by Genzyme Corporation and, until the recent approval of VPRIVTM by Shire plc in February 2010, the only approved enzyme replacement therapy for Gaucher disease. Enzyme replacement therapy is a medical treatment in which recombinant enzymes are injected into patients in whom the enzyme is lacking or dysfunctional. The switch-over study is not a prerequisite for approval of taliglucerase alfa by the FDA. In December 2009 we filed a proposed pediatric investigation plan to the Pediatric Committee of the European Medicines Agency, or EMEA, which was approved during the second quarter of 2010.
     On November 30, 2009, Protalix Ltd. and Pfizer Inc., or Pfizer, entered into an exclusive license and supply 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. 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 EMEA. Protalix Ltd. is also eligible to receive potential milestone payments totaling $50.0 million for the successful achievement of other developmental milestones and to royalties equal to 40% of the net profits earned on Pfizer’s sales of taliglucerase alfa, if any. Pfizer and Protalix Ltd. have agreed to a specific allocation of the responsibilities for the continued development efforts for taliglucerase alfa.
     In July 2009, following a request by the FDA, we submitted a treatment protocol to the FDA in order to address an expected shortage of the current enzyme replacement therapy approved for Gaucher disease. The treatment protocol was approved by the FDA in August 2009. In September 2009, the FDA’s Office of Orphan Product Development granted taliglucerase alfa Orphan Drug Status. In January 2010, the Committee for Orphan Medicinal Products (COMP) of the EMEA, after reviewing all relevant clinical data, recommended that the European Commission grant orphan drug designation to taliglucerase alfa for the treatment of Gaucher disease.
     The Orphan Drug designation in the United States for taliglucerase alfa for the treatment of Gaucher disease provides special status to taliglucerase alfa provided that it meets certain criteria. As a result of the orphan designation, we are qualified for the tax credit and marketing incentives of the Orphan Drug Act of 1983. A marketing application for a prescription drug product that has been designated as a drug for a rare disease or condition is not subject to a prescription drug user fee unless the application includes an indication for other than a rare disease or condition.
     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, therapeutic protein candidates for the treatment of Fabry disease, a rare, genetic lysosomal disorder in humans, an acetylcholinesterase enzyme-based therapy for biodefense, antiTNF, a plant cell expressed recombinant fusion protein made from the soluble form of the human TNF receptor (TNFR) which is being developed as a treatment of certain immune diseases such as rheumatoid arthritis, juvenile idiopathic arthritis and others, and additional undisclosed therapeutic proteins and intoxication treatments, all of which are currently being evaluated in animal studies. In March 2010, we initiated a phase I clinical trial of PRX-105, our plant cell expressed pegylated recombinant acetylcholinesterase product candidate for biodefense indications, which we completed in June 2010. We are currently preparing for further efficacy trials in larger animals.
     Except for the license we have granted to Pfizer, we hold the worldwide commercialization rights to our proprietary development candidates and we intend to establish an internal, commercial infrastructure and targeted sales force to market taliglucerase alfa in Israel and our other products, if approved, in North America, the European Union and in other significant markets, including Israel. In addition, we are continuously evaluating potential strategic marketing partnerships.
     Our business is conducted by our wholly-owned subsidiary, Protalix Ltd., which we acquired through a reverse merger transaction effective December 31, 2006. Since its inception in December 1993, Protalix Ltd. has generated significant losses in connection with its research and development, including the clinical development of taliglucerase alfa. Since we currently do not generate significant revenue from any of our product candidates, we expect to continue to generate losses over the next several years in connection with research and development activities relating to our pipeline of product candidates and the commercialization costs associated with the expected launch of taliglucerase alfa in Israel. Such research and development activities are budgeted to expand over time and will require further resources if we are to be successful. As a result, we believe that our operating losses may be substantial over the next several years. We may need to obtain additional funds to continue the research and clinical development of our programs.
Critical Accounting Policies
     Our significant accounting policies are more fully described in Note 1 to our consolidated financial statements appearing in this Quarterly Report. We believe that the accounting policies below are critical for one to fully understand and evaluate our financial condition and results of operations.

10


Table of Contents

     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.
Results of Operations
Three months ended June 30, 2010 compared to the three months ended June 30, 2009
Revenues
     We recorded revenues of $1.1 million during the three months ended June 30, 2010. The revenues represent the pro rata amortization of the $60.0 million upfront payment and $5.0 million milestone payment we received in connection with our license and supply agreement with Pfizer. No revenues were recorded during the three months ended June 30, 2009.
Research and Development Expenses
     Research and development expenses were $10.5 million for the three months ended June 30, 2010, an increase of $4.3 million, or 69%, from $6.2 million for the three months ended June 30, 2009. The increase resulted primarily from an increase of $728,000 in salaries and an increase of $2.4 million in costs related to consulting and subcontractors and the cost of materials associated with research and development activities and an increase of $528,000 in costs related to our licensing and supply agreement with Pfizer for taliglucerase alfa. The increase is the result of the increased number of clinical sites and patients enrolled in our ongoing clinical trials during the second quarter of 2010 when compared to the second quarter of 2009 and to the increase in the number of projects we have initiated since the beginning of 2010. The increase was partially offset by grants of $480,000 from the OCS during the three months ended June 30, 2010, a decrease of approximately $1.0 million, or 68%, compared to grants equal to $1.5 million received from the OCS during the three months ended June 30, 2009.
     We expect research and development expenses to continue to be our primary expense until we receive regulatory approval of taliglucerase alfa from the FDA, if at all, and potentially thereafter.
General and Administrative Expenses
     General and administrative expenses were $1.3 million for the three months ended June 30, 2010, an increase of $94,000, or 8%, from $1.2 million for the three months ended June 30, 2009 primarily due to an increase of $77,000 in salaries expense.
Financial Expenses and Income
     Financial income was $109,000 for the three months ended June 30, 2010, compared to a financial income of $446,000 for the three months ended June 30, 2009, mainly due to lower interest rates available for short term deposits
Six months ended June 30, 2010 compared to the six months ended June 30, 2009
Revenues
     We recorded revenues of $2.3 million during the six months ended June 30, 2010. The revenues represent the pro rata amortization of the $60.0 million upfront payment and $5.0 million milestone payment we received in connection with our license and supply agreement with Pfizer. No revenues were recorded during the six months ended June 30, 2009.

Research and Development Expenses
     Research and development expenses were $19.4 million for the six months ended June 30, 2010, an increase of $8.1 million, or 72%, from $11.3 million for the six months ended June 30, 2009. The increase resulted primarily from an increase of $2.1 million in salaries, an increase of $2.0 million in materials expenses and an increase of $1.7 million in costs incurred by us related to consulting and subcontractors associated with research and development and an increase of $822,000 in costs related to our licensing and supply agreement with Pfizer for taliglucerase alfa The increase is the result of the increased number of clinical sites and patients enrolled in our ongoing clinical trials during 2010 in compared 2009 and of the increase in the number of projects we have initiated since the beginning of 2010. The increase was partially offset by grants of $1.7 million from the OCS during the six months ended June 30, 2010, a decrease of approximately $1.1 million, or 39%, compared to grants equal to $2.8 million received from the OCS during the six months ended June 30, 2009.
     We expect research and development expenses to continue to be our primary expense until we receive regulatory approval of taliglucerase alfa from the FDA, if at all, and potentially thereafter.
General and Administrative Expenses
     General and administrative expenses were $2.9 million for the six months ended June 30, 2010 an increase of $472,000, or approximately 20%, from $2.4 million for the six months ended June 30, 2009. The increase resulted primarily from an increase of $193,000 in salaries expense and an increase of $161,000 in professional fees.
Financial Expenses and Income
     Financial income was $274,000 for the six months ended June 30, 2010, a decrease of $24,000, or 8%, from $298,000 for the six months ended June 30, 2009.
Liquidity and Capital Resources
Sources of Liquidity
     As a result of our significant research and development expenditures and the lack of any approved products to generate product sales revenue, 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 private sale of our shares of common stock and from sales of convertible preferred and ordinary shares of Protalix Ltd., and an additional $14.2 million in connection with the exercise of warrants issued in connection with the sale of such ordinary shares, through December 31, 2009. In addition, on October 25, 2007, we generated gross proceeds of $50.0 million in connection with an underwritten public offering of our common stock.
     Furthermore, on November 30, 2009, we entered into an exclusive license and supply agreement with Pfizer, pursuant to which 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 achievement of a certain milestone, as provided in the agreement. Protalix Ltd. is also eligible to receive potential milestone payments of up to $50.0 million for the successful achievement of other regulatory-related milestones. Protalix Ltd. is entitled to payments equal to 40% of the net profits earned by Pfizer on its sales of taliglucerase alfa, if any. 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.
     We believe that the funds currently available to us are sufficient to satisfy our capital needs for the foreseeable future.
Cash Flows
     Net cash used in operations was $20.7 million for the six months ended June 30, 2010. The net loss for the six months ended June 30, 2010 of $18.0 million increased due to a decrease of $2.3 million in deferred revenues, an increase of $1.7 million in accounts receivable and a decrease in accounts payable and accruals of $1.0 million but partially offset by $1.5 million in depreciation. Net cash used in investing activities for the six months ended June 30, 2010 was $5.5 million and consisted primarily of purchases of property and equipment.

Table of Contents

     Net cash used in operations was $9.3 million for the six months ended June 30, 2009. The net loss for the six months ended June 30, 2009 of $10.6 million was partially offset by $1.2 million of non-cash share-based compensation and $929,000 of depreciation expense. In addition, net loss increased by $1.1 million due to an increase in accounts receivable. Net cash used in investing activities for the six months ended June 30, 2009 was $4.2 million and consisted primarily of purchases of property and equipment. Net cash provided from financing activities for the six months ended June 30, 2009 was approximately $8,000, consisting of exercise price paid in connection with certain exercise of stock options.
Future Funding Requirements
     Although we have begun to recognize revenues in connection with our licensing and supply agreement with Pfizer for taliglucerase alfa, we expect to continue to generate losses over the next several years in connection with research and development activities relating to our pipeline of product candidates and the commercialization costs associated with the expected launch of taliglucerase alfa in Israel. In addition, we are considering a new manufacturing facility that would meet the FDA requirements for the manufacture of our product candidates, which would increase our capital expenditures significantly.
     We believe that our existing cash and cash equivalents and short-term investments 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 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. The 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 six months ended June 30, 2010 or the six months ended June 30, 2009.
     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 six months ended June 30, 2010 or the six months ended June 30, 2009.

Recently Issued Accounting Pronouncements
     In October 2009, the Financial Accounting Standards Board issued an Accounting Standards Update to ASC 605, ASU No. 2009-13, “Multiple Deliverable Revenue Arrangements,” or ASU 2009-13. ASU 2009-13 provides guidance on whether multiple deliverables in a revenue arrangement exist, how the arrangement should be separated, and how the consideration should be allocated. Pursuant to ASU 2009-13, when vendor specific objective evidence or third party evidence for deliverables in an arrangement cannot be determined, a best estimate of the selling price is required to separate deliverables and allocate arrangement consideration, using the relative selling price method. In addition, the residual method of allocating arrangement consideration is no longer permitted under ASU 2009-13.
     ASU 2009-13 is effective for revenue arrangements entered into or materially modified in fiscal years beginning on or after June 15, 2010. We are currently evaluating the potential impact of ASU 2009-13 on our consolidated financial position, results of operations and cash flows.
Off-Balance Sheet Arrangements
     We have no off-balance sheet arrangements as of each of June 30, 2010 and June 30, 2009.
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 dollar. We are currently in the development stage with 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:
                         
    Six months ended     Year ended  
    June 30,     December 31,  
    2010     2009     2009  
Average rate for period
    3.7589       4.0678       3.933  
Rate at period end
    3.8750       3.9190       3.775  
     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

Table of Contents

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 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 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 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 controls 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. 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 to our internal controls over financial reporting (as defined in Rules 13a-15f and 15d-15f under the Exchange Act) that occurred during the quarter ended June 30, 2010 that has materially affected, or that is reasonably likely to materially affect, our internal control over financial reporting.
