10.3.2 Patent Filing and Prosecution; and Updates. If either Party identifies any invention covered by the HYSEQ Know-How or the Project Intellectual Property for which it would like to seek patent protection, it shall notify the other Party, and the Parties shall review and discuss the filing of a patent application covering such invention. If, after such discussion, the Responsible Party decides to file a patent application covering any such inventions, it shall prepare a patent application and provide the other Party with a copy of such draft application together with a preliminary determination of inventors and scope of claims. Each Party shall advise the other Party within [ * ] of receiving any substantive action or development in the prosecution of any patent application it is responsible for prosecuting pursuant to this Section 10.3 (in particular any actions or developments concerning which countries to continue prosecution of, questions of the scope, issuance or rejection of, any interference involving, any such patent application or any opposition to any such patent application or resulting patent).

10.3.3 Election not to Proceed. On a Patent-by-Patent basis, if a Responsible Party, either prior or subsequent to filing any patent applications for Project Patents, elects not to file, prosecute or maintain such patent applications, or maintain any ensuing Project Patents, it shall notify the other Party within[ * ] prior to allowing such Project Patent to lapse or become abandoned or unenforceable, and the other Party may elect to prepare, file, prosecute, maintain and enforce such Project Patent. Without limiting the foregoing, if a Responsible Party plans to abandon any patent application in any Territory relating to a Project Gene in a Project Patent, the Responsible Party shall promptly notify the other Party, and shall not abandon such patent application for [ * ] after such notification to allow the other Party, if it chooses, to continue to prosecute such patent application solely at its own cost and expense. The costs of filing, prosecuting, and maintaining any Project Patent assumed by a Party pursuant to this Section 10.3.3 shall be the responsibility of such Party (but only if and to the extent such Party, in its sole discretion, decides to incur such costs), and shall not be considered a Shared Patent Cost under Section 10.3.3(a).

(a) Shared Patent Costs. Except for costs and expenses incurred by a Party as set forth above in this Section 10.3.3, unless otherwise mutually agreed by the Parties, all costs of prosecuting and maintaining Joint Project Patents shall be shared [ * ] by the Parties on a [ * ] basis (“Shared Patent Costs”).

Confidential portions of this document have been redacted and have been filed separately with the Commission.

In the event there is a good faith dispute over an amount owed by either Party under this Section 10.3.3(a), the disputed portion of the payment may be delayed, and such payment shall not be considered delinquent pending a resolution of the Parties’ dispute other than with respect to the terms and conditions of Section 13.7.

10.3.4 Reports. The Party performing the prosecution of any patent application under this Section 10.3 shall provide the other Party with a report no less frequently than once every six (6) month period (or as otherwise mutually agreed by the Parties) listing all such patents and patent applications, identifying them by country and patent or application number, and briefly describing the status thereof.

10.3.5 Other Cooperation and Assistance. At the request of the Party performing the prosecution of any patent application under this Section 10.3, the other Party shall cooperate, as reasonably requested, in connection with the prosecution of all such patent applications. Each Party shall make available to the other or its respective authorized attorneys, agents or representatives such of its employees as the other Party in its reasonable judgment deems necessary in order to assist such other Party with the prosecution of such patents. Each Party shall sign or [ * ] have signed and delivered at no charge to the other Party all legal documents reasonably necessary in connection with such prosecution and maintenance. Without in any way limiting anything contained in this Section 10.3, (a) HYSEQ shall act in good faith to advise, and to consult with, DELTAGEN in connection with the preparation and prosecution of the Patent applications included in the HYSEQ Patents as they arise under this Agreement and to mutually seek with DELTAGEN opportunities to prepare and file HYSEQ Patents, with the Parties goal being in each instance [ * ]; and (b) DELTAGEN shall act in good faith to advise, and to consult with, HYSEQ in connection with the preparation and prosecution of the Patent applications included in the DELTAGEN Project Patents and Joint Project Patents as they arise under this Agreement and to mutually seek with HYSEQ opportunities to prepare and file DELTAGEN Project Patents and Joint Project Patents, with the Parties’ goal being in each instance [ * ]. Without limiting the foregoing, HYSEQ may use any Project data and results generated from any Project Knock-out Mouse, including data from the First Pass Phenotypic Analysis, to support prosecution of HYSEQ Patents as reasonably necessary for such prosecution, and such use of data and results will not be considered a violation of the

confidentiality provisions of Article 9 provided that such data and results have already been incorporated into a patent application by DELTAGEN.

10.3.6 HYSEQ and DELTAGEN Project Patents.

13.5 Dispute Resolution.

13.5.1 The Parties shall initially attempt in good faith to resolve any significant controversy, claim, or dispute arising out of or relating to this Agreement or any significant breach thereof (hereinafter collectively referred to as a “Dispute”) through face-to-face negotiations between senior executives of HYSEQ and DELTAGEN. If the Dispute is not resolved within thirty (30) days (or such other period of time mutually agreed upon by the Parties) of commencing such face-to-face negotiations, or if the Party against which a claim has been asserted refuses to attend such negotiations or does not otherwise participate in such negotiations within thirty (30) days (or such other period of time mutually agreed upon by the Parties) from the date of notice of a Dispute, then the Parties agree to submit the Dispute to arbitration as provided herein.

13.5.2 Except as provided in Section 13.5.1 and Sections 3.3.4 and 6.3, all Disputes relating in any way to this Agreement shall be resolved exclusively through arbitration conducted under the auspices of the American Arbitration Association (the “AAA”) pursuant to its Commercial Dispute Resolution Procedures; provided, however, that any disputes between the Parties concerning the infringement or validity of any intellectual property right subject to this Agreement shall be heard by a court of competent jurisdiction.

Unless otherwise mutually agreed by the Parties, any arbitration brought hereunder shall be brought only and exclusively in the State of California. The arbitrators shall hear evidence by each Party and resolve each of the issues identified by the Parties. The arbitrators shall render a formal, binding non-appealable resolution and award on each issue as

expeditiously as possible, but not more than fifteen (15) business days after the hearing. In any arbitration, the prevailing Party shall be entitled to reimbursement of its reasonable attorneys’ fees and the Parties shall use all reasonable efforts to keep arbitration costs to a minimum.

13.5.3 Notwithstanding anything contained herein, in no event shall arbitrators have the power or authority to terminate this Agreement in whole or in part.

13.9 Severability. In the event that any provision of this Agreement shall be held to be unenforceable, invalid or in contravention of applicable law, such provision shall be of no effect, and the Parties shall negotiate in good faith to replace such provision with a provision which effects to the extent possible the original intent of such provision.

13.10 Complete Agreement. This Agreement, including all Exhibits hereto, supersedes all prior understandings, agreements, representations and warranties between the Parties, oral or written with respect to the present subject matter, and comprises the complete agreement between the Parties with respect to the present subject matter.
