A.: WHEREAS Cedars-Sinai and UCLA have disputed amounts paid by Prometheus to Cedars-Sinai and UCLA for certain past royalty payments in connection with the Exclusive License Agreement, as amended, entered into among the parties dated August 14, 1996 the "1996 License"), and in connection with the Exclusive License Agreement entered into between UCLA and Prometheus to govern UCLA's obligations to Prometheus dated December 1, 1999 (the "1999 License")

D.: WHEREAS UCLA and Prometheus intend that the new terms agreed upon in the settlement will be amended into the 1999 License in order to harmonize the 1996 and 1999 Licenses.

NOW, THEREFORE, for good and valuable consideration the receipt and sufficiency of which are hereby acknowledged, the parties enter into this Agreement on the following terms and conditions:

AGREEMENT

I.: MUTUAL SETTLEMENTS.

1. Prometheus, Cedars-Sinai and UCLA, without any of them conceding the correctness of the positions of the other, have agreed to settle the above-described dispute existing among them as of the date hereof in connection with the 1996 License, fully, finally and completely on the following terms:

1.1. In full and final settlement of any claims of Cedars-Sinai and UCLA related to the payments pursuant to the 1996 License through June 30, 2006, the parties have agreed to the following:

(a): As soon as possible following complete execution of this Agreement, Prometheus shall pay to Cedars-Sinai (on behalf of Cedars-Sinai and UCLA) the sum of [***] Dollars ($[***]); and
(b): Prometheus shall calculate Royalties for the quarter ending June 30, 2006 consistent with the calculation of Royalties for the quarter ended March 31, 2006 and will pay such Royalties to Cedars-Sinai and ULCA by August 15, 2006 as required by the License.

1.2. Cedars-Sinai and UCLA shall, in consideration of the payments from Prometheus described in paragraph 1.1 above, refrain from pursuing any and all collection activity, and take all actions necessary to cause any agent or subcontractor to refrain from pursuing any and all collection activity, against Prometheus in connection with any claims resolved by this Agreement. If

Prometheus fails to make the payments described in either paragraphs 1.1(a) or (b) above, Cedars-Sinai and UCLA shall have the right to initiate collection activity for the amount due and owing under this Agreement and this shall be their sole remedy for breach of Prometheus' obligations under Paragraph 1.1 above. For clarification purposes, except as set forth in paragraph 1.1 above, Cedars-Sinai and UCLA shall not have the right to pursue collection activities and are forever giving up their rights to any Royalty claims under the License for any period prior to July 1, 2006.

1.3 Prometheus, Cedars-Sinai and UCLA shall continue to fulfill the obligations set forth in the 1996 License throughout the terms of such 1996 License or in the case of UCLA and Prometheus the 1999 License where applicable, except as modified by this Agreement. Capitalized terms used in this Agreement but not otherwise defined herein shall have the meanings ascribed to them in the License.

2. The parties agree that the initial payment amount described in Section 1.1(a) above is payment in resolution of disputed claims and is being paid to avoid the expense, inconvenience and uncertainty of litigation. The parties hereto understand and acknowledge that this is a compromise settlement without admission of wrongdoing or liability on the part of (i) Cedars-Sinai or UCLA; or (ii) Prometheus.

3. The parties hereby agree that the recipient of the payment described above is responsible for the payment of any and all taxes, if any, and penalties and interest thereon, which may be assessed on the payment amounts by the state, federal or local government.

II.: AMENDMENT TO LICENSE.

Effective as of July 1, 2006, the 1996 License is hereby amended as follows:

1. Section 6(a) of Schedule J—Definition of "Gross Sales Price" is hereby deleted in its entirety and replaced with the following:

"(a) "Gross Sales Price" means, for any period, the gross sales price of Products sold which are or include Royalty Bearing Products (whether in the form of cash, property or otherwise) by Prometheus and its licensees to third parties that are not Affiliates of the selling party (unless such Affiliate is the end user of such Royalty Bearing Product, in which case the amount billed therefor shall be deemed to be the amount that would be billed to a third party in an arm's-length transaction) during such period, less the following items, as allocable to such Royalty Bearing Products: (a) discounts including quantity discounts and contractual allowances, (b) credits, rebates or allowances actually granted upon claims, damaged goods, rejections or returns of Royalty Bearing Products, including recalls, (c) freight, postage, shipping and insurance charges actually allowed or paid for delivery of Royalty Bearing Products, to the extent billed, (d) taxes, duties or other governmental charges (other than income taxes) levied on, absorbed or otherwise imposed on sales of Royalty Bearing Products, and (e) an estimate for bad debts determined in accordance with Prometheus' normal accounting procedures consistently applied; all of the above shall be estimated in accordance with United States generally accepted accounting principles ("GAAP"). In no event shall Royalty Bearing Products used in quality control testing, or Royalty Bearing Products distributed as free marketing samples or charitable contributions, be considered "sold" for purposes of calculating Gross Sales Price."

2. Section 6(c) of Schedule J—Definition of "Royalty Bearing Product". Section 6(c) of Schedule J to the 1996 License is hereby deleted in its entirety and replaced with the following:

"(c) 'Royalty Bearing Product' mean all components, products, features, processes and systems of a Product that (a) are covered by any of the Patent Rights of Future Patent Rights, or (ii) although not covered by a Patent Right or a Future Patent Right, includes or embodies, Technical

Information or Future Technical Information that is licensed to Prometheus hereunder and is not part of the public domain."

3. New Section 6(e) of Schedule J—Definition of "Combination Product". A new Section 6(e) of Schedule J to the 1996 License is hereby added to the 1996 License to read in full as follows:

4. New Section 6(f) of Schedule J—Definition of "Other Components". A new Section 6(f) of Schedule J to the 1996 License is hereby added to the 1996 License to read in full as follows:

"(f) 'Other Component' or 'Other Components' shall mean any and all components, products, features, processes and systems which are not Royalty Bearing Products."

5. Section 1 of Schedule J—Royalties. The following language is hereby added to the end of Section 1 of Schedule J to the 1996 License:

"1. Royalties. Effective July 1, 2006 and notwithstanding anything in the License to the contrary, Prometheus would pay to Cedars-Sinai and UCLA an additional [***] percent ([***]%) of the Gross Sales Price for the Sale of Royalty Bearing Products or Intellectual Property (the "Additional Royalty") until there has been a cumulative total of [***] Dollars ($[***]) of such sales subsequent to June 30, 2006. For clarification purposes, after this aggregate Gross Sales shall have been reached subsequent to June 30, 2006 and the Additional Royalty paid in full by Prometheus, the Additional Royalty shall cease to be owed by Prometheus and the royalty rate shall return to the level established in the 1996 License.

Notwithstanding the foregoing, the following shall apply with respect to Combination Products:

(i) The Royalty and the Additional Royalty (if applicable) payable on each Combination Product for which standalone Current Procedural Terminology ("CPT") values billed for each part of the Combination Product in a particular country in the Territory, shall be based on the following formula:

[***]

(ii) The Royalty payable on each Combination Product for which the Royalty Bearing Products and Other Components contained therein do not have established, stand-alone [***] in a particular country in the Territory, shall be based on the [***] of each or, failing that, then based on the [***] for each. Any disagreement between the parties regarding the value for any aspect of a Combination Product shall be determined by the parties through good faith negotiations.

*** Certain information on this page has been omitted and filed separately with the Securities and Exchange Commission. Confidential treatment has been requested with respect to the omitted portions.

6. Section 4(d) of Schedule J—Late Charges. Section 4(d) of Schedule J to the 1996 License is hereby deleted in its entirety.

7. Section 4(b) of Schedule J—Records and Audits. The following language is hereby added following the third sentence of Section 4(b) of Schedule J:

"Notwithstanding anything in this Agreement to the contrary, such audit right for any period must be (i) exercised within three (3) years of the date of the payment for the period being audited and (ii) may only be exercised once for any period by either CSMC, UCLA or jointly by CSMC and UCLA."

8. Section 2.3—Certain Future Rights. The following language is hereby added to the end of Section 2.3 of the 1996 License:

"2.3. Certain Future Rights. .... Notwithstanding the foregoing, Prometheus desires and Cedars-Sinai is willing to grant to Prometheus additional rights (as specifically set forth in this Section 2.3 and refered to as the "Right of Review") in and to certain aspects of Future Patent Rights identified below and on the following terms and conditions:

(a) In consideration of the grant of the additional rights to certain aspects of Future Patents Rights as identified below as "Cedars-Sinai Future Rights", as soon as possible following complete execution of this Settlement Agreement and Mutual Release and License Amendment, Prometheus shall pay to Cedars-Sinai (on behalf of Cedars-Sinai only) the sum of [***] Dollars ($[***]).

(b) Cedars-Sinai Future Rights for the purposes of this paragraph shall mean and refer to any patents and/or patent applications (i) claiming Inventions not previously disclosed to Prometheus pursuant to Section 2.3 of the License which constitute Future Patent Rights or Future Technical Information; (ii) arising from work conducted by Targan or under the direction of Targan as the sole principal investigator for Cedars-Sinai; (iii) in addition to any patents and/or patent applications (including provisional patent applications) in any other country corresponding to any of the foregoing, and all divisions, continuations, continuations-in-part, reissues, reexaminations, supplementary protection certificates and extensions thereof, whether domestic or foreign, and any patents that issue thereon; and (iv) on which no prior right or obligation to a third party exists. For the sake of clarity, it is understood and agreed by the parties that no additional rights are intended, nor shall it be deemed, to be granted to Future Patent Rights of UCLA and the definition of Cedars-Sinai Future Rights explicity excludes any such rights.

(c) The Right of Review granted to Prometheus by Cedars-Sinai (i) applies to any Cedars-Sinai Future Rights which have gone beyond the [***] day period established in Section 2.3; and (ii) requires Cedars-Sinai to contact Prometheus prior to entering into substantive discussions with a third party for a possible license to any Cedars-Sinai Future Rights. Cedars-Sinai and Prometheus shall have a period of [***] days in which to negotiate the terms of a license for the Cedars-Sinai Future Rights. If Prometheus declines or fails to pursue, or if the parties fail to conclude negotiations for a license to, such Cedars-Sinai Future Rights during the [***] day period, Cedars-Sinai shall have the right to commence discussions with the third party concerning that particular Cedars-Sinai Future Right, provided, however, that any such license must be on terms that are no less favorable than those of the terms last offered by Prometheus, if any, for such Cedars-Sinai Future Rights."
