ARTICLE IV

UNLICENSED MANUFACTURE, USE OR SALE BY INFRINGERS

10. In the event either CMS or CALTECH discovers any unlicensed manufacture, use or sale of Licensed Products, the other party shall be promptly notified of such infringement. CMS may, at its own option and at its own expense, through attorneys of its own election, take appropriate action to terminate or prevent the infringement provided, however, that CMS may not bring an action nor enter into any settlement agreement with an accused infringer without prior written approval of CALTECH, which approval will not be unreasonably withheld. CALTECH agrees to be joined as a party plaintiff to any such action. If CMS takes no action within ninety (90) days of the discovery of the infringement, then CALTECH at its option, may take such action as it deems appropriate including but not limited to the right to license others to make, use and sell the Licensed Products.

11. CALTECH shall not be obligated to bring suit for infringement nor have any responsibility for taking or defending any action whatsoever against or by infringers or alleged infringers; provided, however, that CALTECH shall have the right and option upon giving of written notice to CMS, to participate in any such action, to contribute funds to the prosecution of such action, and to be represented by counsel. Furthermore, CALTECH shall not be obligated to defend the Licensed patents or any claim thereof against challenge or attack by any third party in the United States Patent & Trademark Office or the courts or elsewhere.

12. If CMS engages in litigation or otherwise incurs expense in order to terminate infringement and receives any money by way of damages, license or otherwise as a result of

5

such action, then to the extent that such money exceeds the expense involved, ***% of the excess shall be shared with CALTECH.

13. If any claim that CMS’s practice of the Licensed Patent, in connection with the manufacture and/or sale of Licensed Product, infringes any patents or proprietary rights of any third party, is brought against CMS or its sublicensees, prompt notice of the claim asserted shall be given by CMS to CALTECH. The defense against any such claim will be conducted by CMS at its expense, but CALTECH may have counsel present at its own expense and shall be entitled to participate in the defense of any such claim. No settlement of any such matter, where CALTECH is party to the claim or a defendant, shall be made without the written approval of CALTECH, which approval shall not be unreasonably withheld. During the pendency of any such claim brought against CMS or its sublicensee, royalties due under this Agreement with respect to manufacture and/or sale of Licensed Product in the country of the disputed Patent Rights shall accrue, but not be paid. Such accrued royalties, less all expenses incurred by CMS as a result of such claims, shall be paid to CALTECH upon its successful defense of such claims or upon the settlement thereof with the approval of CMS, which approval shall not be unreasonably withheld.

ARTICLE V

RECORDS, REPORTS AND PAYMENTS

14. CMS shall keep records and books of account in respect of all Licensed Products made and sold by CMS under this agreement, and CMS shall require the same in respect to sales by its distributors, agents, and related companies. CALTECH shall have the right at its expense,

6

during business hours, to examine, or to have its designated auditors examine, such records and books of account, and CMS shall keep the same for at least three years after it pays CALTECH the royalties due for such Licensed Products and require Related Buyers to do the same.

15. On or before the forty-fifth day after the close of each calendar quarter after the first commercial sale, CMS shall render to CALTECH a report in writing, setting forth the number of units of Licensed Products manufactured and the number of units sold during the preceding calendar quarter by CMS and its distributors, agents and related companies, and also setting forth all information necessary to determine the royalties payable hereunder, such report to be accompanied by payment of the royalties shown by said report to be due CALTECH. Royalties and royalty reports for sales by sublicensees are due in the quarter after receipt of such payments and reports by CMS from its sublicensees.

ARTICLE VI

TERMINATION

16. If either party breaches in any material respect any of its obligations hereunder, the other party shall have the right to terminate this agreement and the license granted hereunder by giving the breaching party ninety (90) days written notice thereof, provided, however, that if the breaching party cures the breach within such ninety (90) day period, this agreement shall continue in full force and effect. CMS shall have the right to terminate this agreement at any time after it makes all payments and submits all reports to CALTECH due hereunder by giving CALTECH sixty (60) days written notice. CMS shall have the right to sell inventory on hand at the time of termination.

17. No termination of this agreement shall relieve CMS of the liability for payment of

7

any royalty due for Licensed Products made prior to the effective date of such termination.

(A) a warranty or representation by CALTECH as to the validity or scope of Subject Technology or any claim thereof; or

(B) a warranty or representation that anything made, used, sold, or otherwise disposed of hereunder is or will be free from infringement of rights of third parties; or

(C) an obligation to bring or prosecute actions or suits against third parties for infringement, except to the extent provided in ARTICLE IV; or

ARTICLE VIII

MISCELLANEOUS

21. CMS agrees that it will not use the name of CALTECH, or California Institute of

CMS further agrees that the name of any inventor or employee of CALTECH will not be used by CMS in any such advertising or publicity material without the prior written consent of such inventor or employee.

22. CMS agrees to mark when reasonably possible the appropriate U.S. patent number or numbers on all Licensed Products made under this agreement and to require its sublicensees to do the same.

23. CMS agrees that CALTECH shall have no liability to CMS or to any purchasers or users of Licensed Products made or sold by CMS for any claims, demands, losses, costs, or damages suffered by CMS, or purchasers or users of Licensed Products, or any other party, which may arise out of the manufacture, use, or sale of such Licensed Products, and CMS agrees to defend, indemnify, and hold harmless CALTECH, its trustees, officers, agents, and employees from any such claims, demands, losses, costs, or damages.

24. This contract includes all the agreements of the parties in respect to the subject matter hereof. No claimed oral agreement in respect thereto shall be considered as any part hereof.

Should CMS be declared bankrupt following the filing of a petition in bankruptcy, be declared insolvent or execute an assignment for the benefit of creditors, or should a receiver or trustee be appointed by any court or government agency to administer the affairs and assets of CMS, then, in that event, this agreement shall become terminated, unless the receiver, or trustee, or other assignee, at the time of the assumption of this agreement: (a) cures defaults, if any, or gives reasonable assurance that any such defaults will be timely cured; and (b) provides adequate assurance of future performance under this agreement.

26. This agreement shall be deemed to have been entered into in California and shall be construed and enforced in accordance with California law.

27.
