1.20 Net Sales means, with respect to Licensed RNAi Products, the gross amount invoiced by QUARK or its Affiliates or Sublicensees on sales or other dispositions of such Licensed RNAi Products to third parties which are not Affiliates in those countries where at least a Valid Claim covering such Licensed RNAi Product then exists, less actual bad debts, sales returns and allowances actually paid, granted or accrued, including trade, quantity and cash discounts and any other adjustments, including granted on account of price adjustments, billing errors, rejected goods, damaged or defective goods, recalls, returns, rebates, chargebacks, reimbursements or similar payments granted or given to wholesalers or other distributors, buying groups, health care insurance carriers or other institutions, adjustments arising from consumer discount programs or similar programs, or arising in connection with any Discount or Savings Program (as defined below), customs or excise duties, sales tax, consumption tax, value added tax, and other similar taxes (except income taxes) measured by the production, sale, or delivery of goods in each case only if included as a specific line item on an invoice to such third party or duties relating to sales and any payments in respect of sales to the United States government, any State government or any foreign government, or to any governmental authority, or with respect to any government subsidized program or managed care organization, and charges for freight and insurance related to the return of Licensed RNAi Products and not otherwise paid by the customer. For purposes of this definition of “Net Sales” only, “Discount or Savings Program” means any discount, rebate or reimbursement program applicable to a Licensed RNAi Product under which QUARK or its Affiliates or Sublicensees provides to low income, uninsured or other patients the opportunity to purchase pharmaceutical products at discounted prices.

In the event that a Licensed RNAi Product is sold in any country in the form of a combination product containing one or more therapeutically active ingredients in addition to such Licensed RNAi Product in any year, Net Sales of such combination product will be adjusted by multiplying actual Net Sales of such combination product in such country by the fraction A/(A+B), where A is the average Net Sales prices per daily dose during such year of the Licensed RNAi Product in such country, if sold separately in such country, and B is the average Net Sales prices per daily dose of any product containing the other therapeutically active ingredients in the combination product in such country, if sold separately in such country. If, in a specific country, the product containing the other therapeutically active ingredients in the combination product are not sold separately in such country, Net Sales will be calculated by multiplying actual Net Sales of such combination product by the fraction A/C, where A is the average Net Sales prices per daily dose of the Licensed RNAi Product in such country and C is the average Net Sales prices per daily dose of the combination product in such country. If, in a specific country, the Licensed RNAi Product is not sold separately in such country, Net Sales will be calculated by multiplying actual Net Sales of such combination product by the fraction

(C-B)/C, where B is the average Net Sales prices per daily dose of the product containing the other therapeutically active ingredients in the combination product in such country and C is the average Net Sales prices per daily dose of the combination product in such country. If, in a specific country, both the Licensed RNAi Product and the product containing the other therapeutically active ingredients in the combination product are not sold separately in such country, the Net Sales price for the Licensed RNAi Product and the product containing the other therapeutically active ingredients in the combination product will be negotiated by the Parties in good faith based upon the costs, overhead and profit as are then incurred for the Licensed RNAi Product and all similar substances then being made and marketed by the selling Party and having an ascertainable market price.

In the event QUARK or any of its Affiliates or Sublicensees receive non-monetary consideration in exchange for the sale or other disposition of Licensed RNAi Products to Third Parties which are not Affiliates, Net Sales for such sale or other disposition shall include the fair market value of the non-cash consideration received as a result of such sale or other disposition. If such sale or other disposition occurred in a country where QUARK or such Affiliate or Sublicensee sold the same Licensed RNAi Product in commercial quantities solely for monetary consideration, the fair market value of the non-cash consideration received for such Licensed RNAi Product shall be determined on the basis of the value received in such solely monetary transactions. If QUARK or its Affiliate or Sublicensee did not have sales or other dispositions of Licensed RNAi Product in such country solely for monetary consideration, then the fair market value of such products shall be determined on the basis of all relevant facts and circumstances.

In the event that QUARK or any of its Affiliates or Sublicensees price and sell Licensed RNAi Products in conjunction with other products of QUARK or its Affiliates or Sublicensees at a single price or rate or at a discount for collectively buying such products, then Net Sales with respect to such Licensed RNAi Product shall equal the number of units of the Licensed RNAi Product sold together with the non-Licensed RNAi Products multiplied by the average Net Sales price at which QUARK or any of its Affiliates or Sublicensees sold the Licensed RNAi Product individually to similar customers for similarly sized orders.

Net Sales shall be determined from books and records maintained in accordance with generally accepted accounting principles in the United States, consistently applied throughout the organization and across all products of the entity whose sales of Licensed RNAi Product are giving rise to Net Sales.

1.21 Party means either ALNYLAM or QUARK; Parties means both ALNYLAM and QUARK.

1.22 Phase I Clinical Trial means a study of a Licensed RNAi Product in humans the purpose of which includes the determination of safety and/or pharmacokinetic and pharmacodynamic profile in healthy individuals or patients.

1.23 Phase II Clinical Trial means a study of a Licensed RNAi Product in patients of dose range and efficacy of a Licensed RNAi Product, which is intended to generate sufficient

data to commence a Phase III Clinical Trial.

1.24 Phase III Clinical Trial means a controlled study of a Licensed RNAi Product in patients of the efficacy and safety of a Licensed RNAi Product which is prospectively designed to demonstrate statistically whether such Licensed RNAi Product is effective and safe for use in a particular indication in a manner sufficient to obtain Approval to market such Licensed RNAi Product.

1.25 QUARK means Quark Biotech, Inc., a California corporation, and its successors and assigns.

1.26 Research or Researching means identifying, evaluating, validating and optimizing RNAi Products.

1.27 RNAi Product means a therapeutic product containing, comprised or based on siRNAs or siRNA derivatives or other moieties effective in gene function modulation and designed to modulate the function of the Target through RNA interference.

1.28 Royalty Quarter means each of the four (4) thirteen (13) week periods (i) with respect to the United States, commencing on January 1 of any year, and (ii) with respect to any country in the Territory other than the United States, commencing on December 1 of any year.

1.29 siRNA means a double-stranded ribonucleic acid (RNA) composition designed to act primarily through an RNA interference mechanism that consists of either (a) two separate oligomers of native or chemically modified RNA that are hybridized to one another along a substantial portion of their lengths, or (b) a single oligomer of native or chemically modified RNA that is hybridized to itself by self-complementary base-pairing along a substantial portion of its length to form a hairpin.

1.30 Sublicensee means a third party which is not an Affiliate of QUARK and to whom QUARK has granted a sublicense of all or a portion of the rights granted hereunder. Without limiting the generality of the foregoing, a Sublicensee will be deemed to include any third party (a) who is granted a sublicense hereunder by QUARK pursuant to the terms of the outcome or settlement of any infringement or threatened infringement action and (b) who enters into any form of agreement with QUARK under which such third party will distribute a Licensed RNAi Product in any country in the Territory and who has twenty-five percent (25%) or more of the market share for such Licensed RNAi Product in such country.

1.31 Target means RTP801 as more specifically described in Appendix I, and its encoded gene products, including any fragment or common genetic variants thereof that result from or prevent mutation in, or a single nucleotide polymorphism with respect to such gene.

1.32 Term means the period of time that begins upon the Effective Date and ends upon the expiration or abandonment of all issued patents and filed applications within the ALNYLAM Patent Rights.

1.33 Territory means worldwide. For clarity, at any time the Territory will not include any country to which the exportation or re-exportation of materials, products and related technical data covered by this Agreement is restricted under U.S. export laws, which restriction has not been removed or waived.

Notwithstanding the foregoing, the receiving Party will be entitled to use and disclose Confidential Information of the disclosing Party which (i) was known by the receiving Party or its Affiliates prior to its date of disclosure by the disclosing Party to the receiving Party as demonstrated by legally admissible evidence available to the receiving Party or its Affiliates, (ii) either before or after the date of the disclosure such Confidential Information is lawfully disclosed to the receiving Party or its Affiliates by sources other than the disclosing Party, (iii) either before or after the date of the disclosure by the disclosing Party to the receiving Party such Confidential Information becomes published or otherwise part of the public domain through no fault or omission on the part of the receiving Party or its Affiliates, (iv) is independently developed by or for the receiving Party or its Affiliates without reference to or in reliance upon the Confidential Information as demonstrated by legally admissible evidence available to the receiving Party or its Affiliates, (v) is reasonably necessary to conduct clinical trials or to obtain regulatory approval of Licensed RNAi Products or for the prosecution and maintenance of Patent Rights, (vi) is reasonably required in order for a Party to obtain financing or conduct discussions with Development or Commercialization partners so long as such third party recipients are bound by an obligation of confidentiality or (vii) is required to be disclosed by the receiving Party to comply with applicable laws or regulations or legal process, including without limitation by the rules or regulations of the United States Securities and Exchange Commission or similar regulatory agency in a country other than the United States or of any stock exchange or NASDAQ, provided that the receiving Party provides prior written notice of such disclosure to the disclosing Party and takes

ARTICLE VI — REPORTS, TAXES AND PAYMENTS

6.1 Reports. As to each Royalty Quarter commencing with the Royalty Quarter during which the First Commercial Sale occurs, [ * ] after the end of such Royalty Quarter (if QUARK has not entered into an agreement with a Sublicensee) and within [ * ] after the receipt by QUARK from a Sublicensee of such Sublicensee’s report, as required by such Sublicensee’s sublicense for each Royalty Quarter (if QUARK has entered into an agreement with a Sublicensee), QUARK will deliver to ALNYLAM a written report showing, on a country-by-country basis, the Net Sales of Licensed RNAi Products calculated under GAAP and its royalty obligation for such quarter with respect to such Net Sales under this Agreement together with wire transfer of an amount equal to such royalty obligation. All Net Sales will be segmented in each such report according to sales by QUARK and each Affiliate and Sublicensee, as well as on a product-by-product basis, including the rates of exchange used to convert Net Sales to United States Dollars from the currency in which such sales were made. For the purposes of this Agreement, the rates of exchange to be used for converting Net Sales to United States Dollars will be [ * ].

6.2 Tax Withholding. QUARK will use all reasonable and legal efforts to reduce tax withholding with respect to payments to be made to ALNYLAM. Notwithstanding such efforts, if QUARK concludes that tax withholdings under the laws of any country are required with respect to payments to ALNYLAM, QUARK will make the full amount of the required payment to ALNYLAM after any tax withholding. In any such case, QUARK shall provide ALNYLAM with a written explanation of such withholding and original receipts or other evidence reasonably desirable and sufficient to allow ALNYLAM to document such tax withholdings for purposes of claiming foreign tax credits and similar benefits. For purposes of clarity, any payment due to ALNYLAM in respect of fees set out in Article III of this Agreement will be paid in the full amount specified after any tax withholding, with the amount of any tax withholding associated with such payments to be paid by QUARK to the appropriate government authority.

6.3 Payments. Unless otherwise agreed by the Parties, all payments required to be made under this Agreement will be made in United States Dollars via wire transfer to an account designated in advance by the receiving Party.

6.4 Audits.

(a) At any given point in time, QUARK will have on file and will require its Affiliates and Sublicensees to have on file complete and accurate records for the last [ * ] of all Net Sales of Licensed RNAi Products (including associated data). ALNYLAM will have the right, [ * ] during each [ * ] period, to retain at its own expense an independent qualified certified public accountant reasonably acceptable to QUARK to review such records upon reasonable notice, during regular business hours. If the audit demonstrates that the payments owed under this Agreement have been understated, QUARK will pay the balance to ALNYLAM together with interest on such amounts from the date on which such payment obligation accrued at a rate equal to [ * ]. If the underpayment is greater than [ * ] of the amount owed, then QUARK will reimburse ALNYLAM for its reasonable out-of-pocket costs of the audit. If the audit demonstrates that the payments owed under this Agreement have been overstated, ALNYLAM will credit the balance against the next payment due from QUARK (without interest).

(b) QUARK shall require that the terms of any sublicense under its rights in this Agreement are fully in compliance with the terms and conditions of the in-licenses governing ALNYLAM’s rights under the ALNYLAM Patent Rights identified on Exhibit B, including without limitation, all obligations with respect to maintenance of records and audit rights. ALNYLAM will provide QUARK in a timely manner with a true and complete copy (subject to redaction of financial and other information not material to ALNYLAM’s ability to sublicense rights licensed thereunder to QUARK under this Agreement) of all such in-licenses.

ARTICLE VII — INDEMNIFICATION AND INSURANCE

7.1 QUARK Indemnification. QUARK agrees to indemnify and hold harmless ALNYLAM and its Affiliates, and their respective agents, directors, officers and employees and their respective successors and assigns (the “ALNYLAM Indemnitees”) from and against any and all losses, costs, damages, fees or expenses (“Losses”) incurred by an ALNYLAM Indemnitee arising out of or in connection with any claim, suit, demand, investigation or proceeding brought by a third party (“Claim”) based on (a) the development, use, manufacture, distribution or sale of any Licensed RNAi Product by QUARK or any of its Affiliates or Sublicensees, including, but not limited to, any claims made against ALNYLAM by third parties alleging infringement, injury, damage, death or other consequence occurring to any person claimed to result, directly or indirectly, from the possession, use or consumption of, or treatment with, any Licensed RNAi Product, whether claimed by reason of breach of warranty, negligence, product defect or otherwise, and regardless of the form or forum in which any such claim is made, (b) any breach of any representation, warranty or covenant of QUARK in this Agreement, and (c) actions taken or omitted to be taken by QUARK or its Affiliates, subcontractors or Sublicensees, or the employees, agents or representatives of any of them in performing QUARK’s obligations under this Agreement.

The above indemnification shall not apply to the extent that any Losses are due to a material breach of any of ALNYLAM’s representations, warranties, covenants and/or obligations under this Agreement.

7.2 Insurance. With respect to its activities under this agreement, QUARK will secure and maintain in full force and effect throughout the term of this Agreement (and for at least [ * ] thereafter for claims made coverage), the following types and amounts of insurance coverage with carriers having a minimum AM Best rating of A, with per claim deductibles that do not exceed twenty thousand U.S. dollars ($20,000):

The Parties acknowledge that the exportation from the United States of materials, products and related technical data (and the re-export from elsewhere of United States origin items) may be subject to compliance with United States export laws, including without limitation the United States Bureau of Export Administration’s Export Administration Regulations, the Act and regulations of the FDA issued thereunder, and the United States Department of State’s International Traffic and Arms Regulations which restrict export, re-export, and release of materials, products and their related technical data, and the direct products of such technical data. The Parties agree to comply with all applicable exports laws and to commit no act that, directly or indirectly, would violate any United States law, regulation, or treaty, or any other international treaty or agreement, relating to the export, re-export, or release of any materials, products or their related technical data to which the United States adheres or with which the United States complies.

8.2 Delays. The Parties acknowledge that they cannot be responsible for any delays attributable to export controls which are beyond the reasonable control of either Party.

Expiration or termination of this Agreement shall not relieve the Parties of any obligation accruing prior to such expiration or termination. Any expiration or termination of this Agreement shall be without prejudice to the rights of either Party against the other accrued or accruing under this Agreement prior to expiration or termination, including without limitation the obligation to pay royalties for Licensed RNAi Product sold prior to such expiration or termination.

10.2 Dispute Resolution; Arbitration Procedures.

(a) In the event of any dispute, controversy or claim arising out of or relating to this Agreement or the breach thereof, the Parties will try to settle such dispute, controversy or claim amicably between themselves, including referring such dispute, controversy or claim to the Chief Operating Officer of ALNYLAM or his designee, and the Chief Executive Officer of QUARK, or any other officer designated by such Chief Executive Officer. In the event that after [ * ] the designated officers of both Parties fail to resolve the matter, either Party may submit such dispute, controversy or claim that is not an “Excluded Claim” for resolution by binding arbitration under the Rules of Arbitration of the International Chamber of Commerce. Judgment on the arbitration award may be entered in any court of competent jurisdiction. The arbitration will be conducted in New York, New York and the language of all communications and proceedings relating to the arbitration will be English.

Within thirty (30) days after initiation of arbitration, each Party shall select one person to act as arbitrator and the two Party-selected arbitrators shall select a third arbitrator within thirty (30) days of their appointment. If the arbitrators selected by the Parties are unable or fail to agree upon the third arbitrator, the Parties shall select two replacement arbitrators to replace the arbitrators originally selected, which replacement arbitrators shall select a third arbitrator within thirty (30) days of their appointment. The Parties agree (a) to meet with the arbitrator(s) within thirty (30) days of selection and (b) to agree at that meeting or before upon procedures for discovery and as to the conduct of the hearing which will result in the hearing being concluded within no more than six (6) months after selection of the arbitrator(s) and in the award being rendered within thirty (30) days of any post-hearing briefing, which briefing will

In the event the Parties cannot agree upon procedures for discovery as set forth in (a) above, the arbitrator(s) shall provide that discovery be limited so that the schedule may be met without difficulty and so that neither side obtains more than a total of twenty-five (25) hours of deposition testimony from all witnesses, including both fact and expert witnesses, or serves more than ten (10) individual requests for documents or ten (10) individual requests for admission or interrogatories. In no event will the arbitrator(s), absent agreement of the Parties, allow more than three (3) days per side for the hearing or more than a total of six (6) days for the hearing. Multiple hearing days will be scheduled consecutively to the greatest extent possible.

(c) Either Party may apply to the arbitrators for interim injunctive relief until the arbitration award is rendered or the controversy is otherwise resolved. Either Party also may, without waiving any remedy under this Agreement, seek from any court having jurisdiction any injunctive or provisional relief necessary to protect the rights or property of that Party pending the arbitration award. The arbitrators shall have no authority to award punitive or any other type of damages not measured by a Party’s compensatory damages. Each Party shall bear its own costs and expenses and attorneys’ fees and an equal share of the arbitrators’ fees and any administrative fees of arbitration.

(d) Except to the extent necessary to confirm an award or as may be required by law, neither a Party nor an arbitrator may disclose the existence, content, or results of an arbitration without the prior written consent of both Parties. In no event shall an arbitration be initiated after the date when commencement of a legal or equitable proceeding based on the dispute, controversy or claim would be barred by the applicable New York statute of limitations.

(e) The Parties agree that, in the event of a dispute over the nature or quality of performance under this Agreement, neither Party may terminate this Agreement until final resolution of the dispute through arbitration or other judicial determination. The Parties further agree that any payments made pursuant to this Agreement pending resolution of the dispute shall be refunded if an arbitrator or court determines that such payments are not due.

(f) As used in this Section 10.2, the term “Excluded Claim” shall mean a dispute, controversy or claim that concerns (a) the validity or infringement of a patent, trademark or copyright; or (b) any antitrust, anti-monopoly or competition law or regulation, whether or not statutory. Excluded Claims shall be resolved in a court of competent jurisdiction.

10.3 Publicity. No disclosure of the existence of, or the terms of, this Agreement may be made by either Party, and no Party shall use the name, trademark, trade name or logo of the other Party or its employees in any publicity, news release or disclosure relating to this Agreement or its subject matter, without the prior express written permission of the

other Party, except as may be required by law or as set forth in this Section 10.3. The Parties acknowledge and agree that, upon and following the Effective Date, one or both of the Parties intends to issue a press release announcing the execution of this Agreement. Notwithstanding the foregoing, the Parties agree to consult with each other reasonably and in good faith with respect to the text and timing of such press releases prior to the issuance thereof. Either Party may issue such press releases or otherwise make such public statements or disclosures (such as in annual reports to stockholders or filings with the Securities and Exchange Commission) as it determines, based on advice of counsel, are reasonably necessary to comply with applicable laws and regulations. In addition, following any initial press release(s) announcing this Agreement or other public disclosure approved by both Parties, either Party shall be free to disclose, without the other Party’s prior written consent, the existence of this Agreement, the identity of the other Party and those terms of the Agreement which have already been publicly disclosed in accordance herewith.

10.4 Force Majeure. No failure or omission by the Parties in the performance of any obligation of this Agreement will be deemed a breach of this Agreement or create any liability if the same will arise from any cause or causes beyond the control of the Parties, including, but not limited to, the following: acts of God; acts or omissions of any government; any rules, regulations or orders issued by any governmental authority or by any officer, department, agency or instrumentality thereof; fire; flood; storm; earthquake; accident; war; rebellion; insurrection; riot; and invasion.

10.5 Consequential Damages. NEITHER PARTY (INCLUDING ITS AFFILIATES AND SUBLICENSEES) SHALL BE LIABLE UNDER THIS AGREEMENT FOR ANY SPECIAL, INCIDENTAL, OR CONSEQUENTIAL DAMAGES OR FOR LOSS OF PROFIT OR LOST REVENUE, EVEN IF SUCH PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. NOTWITHSTANDING THE FOREGOING, NOTHING IN THIS SECTION 10.5 IS INTENDED TO OR SHALL LIMIT OR RESTRICT THE INDEMNIFICATION RIGHTS OF A PARTY OR DAMAGES AVAILABLE FOR A PARTY’S BREACH OF CONFIDENTIALITY OBLIGATIONS IN ARTICLE V.

10.6 Assignment.

(a) This Agreement and any of its rights and obligations may not be assigned or otherwise transferred by either Party without the prior written consent of the other Party, which consent may not be unreasonably withheld, delayed or conditioned; provided, however, that either Party may assign this Agreement, without the consent of the other Party, in connection with such Party’s merger, consolidation or transfer or sale of all or substantially all of the assets of such Party; provided further that the successor, surviving entity, purchaser of assets, or transferee, as applicable, expressly assumes in writing such Party’s obligations under this Agreement. Any purported assignment in contravention of this Section 10.6 shall,

at the option of the non-assigning Party, be null and void and of no effect.
