WHEREAS, in connection with the Quark License, Pfizer has requested certain clarifications regarding the Atugen License; and

WHEREAS, in order to assure to Pfizer the full enjoyment of all rights to be granted to Pfizer under the Quark License, Pfizer desires to obtain an option to acquire under certain circumstances from Atugen certain licenses from Atugen relating to siRNA molecules directed to silencing the RTP801 gene.

NOW, THEREFORE, in consideration of the mutual covenants and agreements provided herein, the parties have executed this Amendment and Option:

I. Definitions. For purposes of this Amendment and Option the following definitions shall be applicable:

A. Save as otherwise provided herein, all terms defined in the License Agreement (as hereinafter defined) when used herein shall have their defined meanings as specified in the License Agreement.

B. “Atugen License” means the Collaboration Agreement, dated December 6, 2004, among Atugen, QBI and QEL, as amended by the Amendment dated May 25, 2006.

C. “Quark License” means the license agreement between QBI and Pfizer in the form set forth in Exhibit A, or such amended form upon which QBI and Pfizer may agree from time to time, subject to Section III C below, attached hereto and made a part hereof.

D. “License Agreement” means the license agreement between Atugen and Pfizer in the form set forth in Exhibit B, attached hereto and made a part hereof, as amended from time to time in accordance with its terms.

The terms of said license are those contained in the License Agreement which shall become effective as provided herein. The option granted hereunder shall be exercisable by Pfizer in the event the Atugen License is terminated or under any circumstances under which Quark shall no longer, pursuant to the Atugen License, have license rights to the Atugen Existing IP or the Joint Program IP. Upon the occurrence of such termination of the Atugen License or such loss of such license rights, Atugen shall promptly notify Pfizer, and, within thirty (30) days of receipt of such notice, Pfizer shall have the right, at its sole discretion, to exercise the option granted hereunder. The option shall be exercised by Pfizer by sending a notice to Atugen, stating Pfizer’s desire to exercise the option provided herein; thereafter Atugen and Pfizer shall promptly sign and deliver in duplicate the License Agreement, to be dated the date of such execution, whereupon the License Agreement shall become effective as of the date on which Quark shall have no longer any license rights to the Atugen Existing IP or the Joint Program IP.

III. Amendment of Atugen License and Approval and Terms of Quark License.

A. Notwithstanding to the contrary any provisions of the Atugen License, (i) Quark shall be deemed to be in full compliance with the provisions of the Atugen License by entering into and performing the Quark License in accordance with its terms, and (ii) Pfizer shall have no obligations or liability to Atugen or to Quark pursuant to the Atugen License.

B. Atugen hereby consents and agrees to the execution, delivery and performance by Quark and Pfizer of the Quark License.

1. All licenses granted by Quark to Atugen under Section 6.1 of the Atugen License are hereby terminated and all obligations of Atugen pursuant to the Atugen License, whose lawful performance depends on Atugen having the continued benefit of any such license are also hereby terminated.

2. All intellectual property rights of Quark arising under the Atugen License have been and remain vested solely in QBI rather than QEL, which has been performing research and development services on behalf of QBI.

3. References in Sections 4.8.1 and 4.8.4 of the Atugen License to “best efforts” are hereby amended to be “commercially reasonable efforts.”

4. (a) Section 8.1.2 of the Atugen License is hereby deleted and replaced by the following wording:

“For Products that are developed and/or sold by sub-licensees, Atugen shall be entitled to receive a royalty of [ * ] of the Sublicense Royalties. For purposes of this Section, and in the case where Pfizer Inc. is the sublicensee, the Sublicense Royalties shall be the payments due from Pfizer Inc. to Quark under Sections 5.7 and/or 5.8, subject to Sections 5.9 to 5.12 inclusive and under Section 7.9, of the sublicence from Quark to Pfizer Inc.”

(b) In Section 8.2.2 of the Atugen License, the words “…necessary to commercialize such Party’s Products (the “Royalty Offset”) against the royalties payable by the

For clarity, no payments shall be due to Atugen arising out of payments made under Sections 4.8 to 4.12 inclusive of the Quark License.

(e) The “Products” definition in Section 1 of the Atugen License is hereby deleted and replaced by the following:

“‘Products’ means RNAi products that are (i) based on the Atugen Existing IP or discovered, developed or produced using the Atugen Existing IP, (ii) based on the Quark Existing IP and (iii) directed to the 801 gene.”

5. The second sentence of Section 12 of the Atugen License is hereby amended to read in full as follows: “The arbitration shall be conducted in London, England, according to the rules of the London Court of International Arbitration (“LCIA”) and the laws of England.”

6. Atugen consents to Quark’s delegation to Pfizer, in accordance with the Quark License, of responsibility and control over the prosecution and enforcement of the Joint Patents (as defined in the Atugen License) which are currently being prosecuted by Quark. Atugen shall not have the right or obligation to enforce Atugen Existing IP or the Joint Patents relating to the QBI Products; provided, however, that Quark shall pay to Atugen [ * ] of any damages, settlements, accounts of profits or other financial compensation received by Quark pursuant to Section 7.9 of the Quark License.

7. So long as the Quark License remains in effect, Quark shall be deemed to have satisfied the Development Milestones of Section 11.4 of the Atugen License (as defined in the Atugen License). If the Quark License terminates for any reason, then:

(a) The sole remaining Development Milestone under the Atugen License applicable to Quark shall be to [ * ] within [ * ] from termination of the Quark License (and all other Development Milestones shall be cancelled); and

(b) If Quark thereafter grants a sublicense under the Atugen License, there shall be no Development Milestones, but Quark and the new sublicensee(s) shall remain

obligated to use commercially reasonable efforts to develop a QBI Product (as defined in the Atugen License).

IV. Atugen Warranties. Atugen hereby warrants to Pfizer that:

A. Other than the Atugen License, Atugen has not entered into any agreement with any other person or firm granting any rights or licenses to the Atugen Existing IP or the Joint Program IP to conduct activities within the scope of the licenses granted to Pfizer in Sections 3.1 and 3.2 of the License Agreement.

and each payment shall be accompanied by a report identifying the Licensed Products, Net Sales, and the amount payable to Atugen, as well as computation thereof.

ARTICLE 6

PATENTS

6.1 Atugen and Pfizer shall cooperate in connection with the continued prosecution and maintenance by Atugen or Pfizer, as the case may be, of the Patent Rights listed on Schedules A1, A2 and A3 which identifies which party shall be responsible for the prosecution and maintenance of such Patent Rights. Each party shall pay all prosecution and maintenance costs for the full life of the Patent Rights for which it is responsible. Neither party shall abandon any Patent Rights without at least [ * ] prior written notice to the other. If either chooses to abandon such Patent Rights, the other party shall have the option to [ * ] such Patent Rights [ * ] and to continue the prosecution and maintenance of such Patent Rights and related applications [ * ]. Each party shall have reasonable access to all documentation, filings and communications to or from the respective patent offices and shall, upon request, be kept advised as to the status of all pending applications to the extent pertaining to Patent Rights licensed hereunder. Each party, its agents and attorneys will give due consideration to all suggestions and comments of the other party regarding any aspect of such patent prosecutions.

6.2 If any claim relating to the Patent Rights licensed hereunder becomes within any country the subject of a judgment, decree or decision of a court, tribunal, or other authority of competent jurisdiction, which judgment, decree, or decision is or becomes final (there being no further right of review) and adjudicates the validity, enforceability, scope, or infringement of the same, the construction of such claim in such judgment, decree or decision shall be followed thereafter in such country in determining whether any product is licensed hereunder, not only as to such claim but also as to all other claims in such country to which such construction reasonably applies. If at any time there are two or more conflicting final judgments, decrees, or decisions with respect to

the same claim, the decision of the higher tribunal shall thereafter control, but if the tribunal be of equal rank, then the final judgment, decree, or decision more favorable to such claim shall control unless and until the majority of such tribunals of equal rank adopt or follow a less favorable final judgment, decree, or decision, in which event the latter shall control.

6.3 Each of the parties will promptly notify the other in the event of any potential infringement of the Patent Rights licensed hereunder by any third party or any claims of alleged infringement by Pfizer or Atugen with respect to the manufacture, use, sale, offer for sale or importation of Licensed Products. Pfizer shall have the right, but not the obligation, to defend or institute litigation in connection therewith, and any such litigation shall be at Pfizer’s expense; provided, however Atugen shall be entitled to receive [ * ] of any amounts to which Quark is or would be entitled under Section 7.9 of the Quark License. Atugen, upon request of Pfizer, agrees to join in any such litigation at Pfizer’s expense and to cooperate reasonably with Pfizer. If Pfizer fails to defend any action for alleged infringement by Pfizer or Atugen with respect to the manufacture, use, sale, offer for sale or importation of Licensed Products, Atugen shall have the right (but not the obligation) upon [ * ] prior notice to Pfizer, at Atugen’s expense, to defend any such litigation. Atugen shall not have the right to enforce any potential infringement of the Patent Rights licensed hereunder relating to the Licensed Products.

INDEMNIFICATION

9.1 Pfizer agrees to indemnify, defend and hold harmless Atugen, its Affiliates and its and their directors, officers, agents and employees (the “Atugen Parties”) from and against any and all Losses (as hereinafter defined) incurred, suffered or sustained by the Atugen Parties from any claims, actions, suits, proceedings, liabilities or obligations arising out of or resulting from the development (including clinical trials), marketing, manufacture, use, processing, packaging, sale, offer for sale, importation, distribution of any Licensed Product, in each case by Pfizer, its Affiliates or sublicensees. The foregoing indemnity shall not apply to the extent that any Loss arises from or is the result of gross negligence or intentional misconduct on the part of the

Atugen Parties. The foregoing indemnity shall also be subject to the provisions of Section 9.2.

9.2 In the event any third party asserts any claim in respect to any matter to which the indemnification in Section 9.1 relates, the Atugen Parties shall not make any admission concerning such claim, but shall promptly notify Pfizer of the claim, and Pfizer shall be entitled, but not obliged, to manage and control, at its sole expense, the defense of the claim and its settlement. The benefit of any indemnity by Pfizer under this Agreement in respect of any claim shall not apply to the Atugen Parties if any admission made by such party or any failure by such party to notify Pfizer of the claim materially prejudices the defense of such claim. If Pfizer elects to defend such claim, it shall give prompt notice to Atugen. If Pfizer does not give such notice and does not proceed diligently to defend the Atugen Parties within twenty (20) days after receipt of notice of the claim, Pfizer shall be bound by any defense or settlement made by the Atugen Parties and shall reimburse the Atugen Parties for its expenses related to the defense or settlement of the third party claim. If Pfizer elects to defend the claim and gives notice to Atugen and proceeds diligently to defend the Atugen Parties, then the Atugen Parties shall not settle any claim for which it is seeking indemnification without the prior consent of Pfizer. The Atugen Parties shall, if requested by Pfizer, and at Pfizer’s expense, cooperate in all reasonable respects in the defense of such a third party claim which is being managed and controlled by Pfizer. The Atugen Parties may, at its option and expense, be represented by counsel of its own choice in any action or proceeding arising out of such claim; provided, however, Pfizer shall not be liable for any litigation costs or expenses incurred without its consent, by the Atugen Parties, where such action or proceeding is under the control and management of Pfizer.

9.3 Any indemnification hereunder shall be made net of any insurance proceeds recovered by the Atugen Parties; provided, however, that if, following the payment of the Atugen Parties of any amount under this Section 9, such Atugen Party recovers any insurance proceeds in respect of the claim for which such indemnification payment was made, the Atugen Party shall promptly pay an amount equal to the amount of such proceeds (but not exceeding the amount of such indemnification payment) to Pfizer.

9.4 For purposes of this Section 9, “Losses” shall mean any and all damages, fines, fees, penalties, judgments, deficiencies, losses and expenses (including without limitation interest, court costs, reasonable fees of attorneys, accountants and other experts or other expenses of litigation or other proceedings or of any claim, default or assessment).
