(a) a non-exclusive license to use, possess, culture and employ the LICENSED CELL LINE at its business premises solely in the United States;

(b) a worldwide, non-exclusive license to the LICENSED MONOCLONAL ANTIBODY to make and have made, to use, to sell, have sold and offer for sale the LICENSED PRODUCTS and the LICENSED SERVICES in the FIELD for the term of this Agreement (collectively the “Licenses”). Notwithstanding any other provision of this Agreement, (1) LICENSEE and its Affiliates shall not use the LICENSED CELL LINE or LICENSED MONOCLONAL ANTIBODY for any purpose other than that expressly described in this Agreement (2) shall not transfer the LICENSED CELL LINE to any third party or AFFILIATE for any purpose except to a sublicensee as provided in Section

15.2 Amendments. This Agreement may not be amended except by an instrument in writing signed by both parties.

15.3 Assignability. The Agreement shall be binding on the parties hereto and upon their respective heirs, administrators, successors and assigns. This Agreement may not be assigned by LICENSEE or by operation of law without the prior written consent of FHCRC, which consent shall not be unreasonably withheld; except either party may assign this Agreement, without such consent, to (i) an AFFILIATE of such party; or (ii) an entity that acquires all or substantially all of the business or assets of such party to which this Agreement pertains, whether by merger,

13

reorganization, acquisition, sale or otherwise, and that agrees in writing to be strictly bound by the terms and conditions of this Agreement.

15.4 Non-Profit Status. LICENSEE acknowledges that FHCRC is a non-profit organization qualifying for and holding the status of an exempt organization under Section 50l(c)(3) of the United States Internal Revenue Code. If the Internal Revenue Service determines, or a determination by FHCRC based on advice of legal or tax counsel is reasonably made, that any part or all of this Agreement will jeopardize FHCRC’s Section 501(c)(3) status, the parties agree to meet and confer in good faith to amend this Agreement to the extent necessary to satisfy Internal Revenue Service requirements for retention of FHCRC’s Section 50l(c)(3) status. If FHCRC and LICENSEE cannot agree within 30 days after commencing negotiations regarding the amendments to be made to this Agreement in order for FHCRC to retain its Section 501(c)(3) status, FHCRC may terminate this Agreement effective upon giving written notice to LICENSEE of termination under this Section 10.

15.5 Conflicts with Grants. LICENSEE understands and acknowledges that agreements between FHCRC and agencies of the United States Government funding FHCRC’s programs may contain clauses granting patent and/or other rights to the agencies or the U.S. Government; LICENSEE agrees that the rights granted to it under this Agreement shall be subject to any rights of the agencies and the U.S. Government. If a conflict arises, the provisions of any U.S. Government agency funding agreement and/or regulation shall prevail over any conflicting provisions of this Agreement and FHCRC will have no liability to LICENSEE as a result of such conflict. If such a conflict arises or is reasonably anticipated, FHCRC will promptly give notice to LICENSEE of the nature of the conflict and copies of any correspondence relating thereto in accordance with Section 14.1.

15.6 Use of Name. Neither party shall use the name of the other party or reveal the terms of this Agreement in any publicity or advertising without the prior written approval of the other party, except that (i) either party may use the text of a written statement approved in advance by both parties without further approval; (ii) either party shall have the right to identify the other party and to disclose the terms of this Agreement as required by applicable securities laws or other applicable law or regulation; and (iii) either party may disclose that a licensing relationship exists between the parties and may disclose the name of the other party in that context.

15.7 Written Notices. All letters, documents, or other materials of a written or physical nature, required by or relating to this Agreement shall be in English and sent to the party at the address given in Article 14.

15.8 Independent Parties. The parties to this Agreement are independent contractors and not agent of the other. This Agreement shall not constitute a partnership or joint venture, and neither party may be bound by the other to any contract, arrangement or understanding except as specifically stated herein.

15.9 Enforceability. Should a court of competent jurisdiction later consider any provision of this Agreement to be invalid, illegal, or unenforceable, it shall be considered severed from this Agreement. All other provisions, rights and obligations shall continue without regard to the

14

severed provision, provided that the remaining provisions of this Agreement are in accord with the intention of the parties.

15.10 Actions. In the event any party to this Agreement commences any action or proceeding, including an appeal of an action or proceeding, against the other, or otherwise retains an attorney, by reason of any breach or claimed breach of any provision of this Agreement, or to seek a judicial declaration of rights hereunder or judicial or equitable relief, the prevailing party in such action or proceeding shall be entitled to recover its reasonable attorneys’ fees and costs. At the option of FHCRC, venue of any such legal or equitable action shall lie in Seattle, Washington. LICENSEE hereby submits to the jurisdiction of the Federal District Court of Western Washington located in Seattle, Washington, and hereby agrees to accept service of process by certified mail, return receipt requested, effective upon delivery to LICENSEE.

15.11 Force Majeure. LICENSEE and FHCRC shall not be liable for loss, damage, detention or delay resulting from any cause whatsoever beyond its reasonable control or resulting from a force maj cure, including, without limitation, fire, flood, strike, lockout, civil or military authority, insurrection, war, embargo, container or transportation shortage or delay of suppliers due to such causes, and delivery dates shall be extended to the extent of any delays resulting from the foregoing or similar causes. The party so affected shall give prompt notice to the other party of such cause, and shall take whatever reasonable steps are necessary to relieve the effect of such cause as rapidly as reasonably possible. The party giving such notice shall thereupon be excused from such of its obligations hereunder as it is thereby disabled from performing for so long as it is so disabled and for thirty (30) days thereafter, whichever is longer; provided, however, that such affected party commences and continues to take reasonable and diligent actions to cure such cause.
