The Parties shall take reasonable measures to assure that no unauthorized use or disclosure is made by others to whom access to such information is granted.

5.2 Corixa and Prometheus Permitted Disclosures. Nothing herein shall be construed as preventing Corixa or Prometheus from disclosing any information received from the other Party to: (i) an Affiliate of Corixa or Prometheus, or (ii) a Third Party in connection with a potential partnering transaction, investment, loan, merger or acquisition transaction with Corixa or Prometheus; provided, however, that such Affiliate, licensee, distributor or Third Party has undertaken in writing a similar obligation of confidentiality with respect to the confidential information.

5.3 Required Disclosures. Subject to the licenses granted to Prometheus hereunder, all confidential information disclosed by one Party to the other Party shall remain the property of the disclosing Party. In the event that a court or other legal or administrative tribunal, directly or through an appointed master, trustee or receiver, assumes partial or complete control over the assets of a Party to this Agreement based on the insolvency or bankruptcy of such Party, the bankrupt or insolvent Party shall promptly notify, with a copy to the other Party, the court or other tribunal (i) that, subject to the licenses granted to Prometheus hereunder, confidential information received from the other Party under this Agreement remains the property of the other Party and (ii) of the confidentiality obligations under this Agreement. In addition, the bankrupt or insolvent Party shall, to the extent permitted by law, take all steps necessary or desirable to maintain the confidentiality of the other Party's confidential information and to insure that the court, other

tribunal or appointee maintains such information in confidence in accordance with the terms of this Agreement.

5.4 Press Release. The Parties may disclose the nature of this Agreement in a joint press release following execution; provided, however, that the releasing Party shall obtain the prior consent of the other Party on the text of such press release, such consent not to be unreasonably withheld.

SECTION 6
INVENTIONS; FILING, PROSECUTION AND MAINTENANCE OF PATENT RIGHTS

6.1 Inventions. Subject to the licenses granted to Prometheus hereunder, Corixa shall own the entire right, title and interest in and to any and all Licensed Patents and Licensed Technology supplied to Prometheus. As between the Parties, Prometheus shall be the sole owner of all inventions, discoveries, and know-how that pertain to the Licensed Products and Licensed Technology (and any improvements thereto) which are made solely by Prometheus, or jointly by Prometheus and others (other than Corixa), during the Term.

6.2 Filing, Prosecution and Maintenance. As between the Parties, Prometheus shall have complete control and discretion regarding any prosecution or maintenance of the Licensed Patents and Prometheus shall be solely responsible for all costs and expenses related to prosecution and maintenance of the Licensed Patents.

Each of Prometheus and Corixa shall hold all information disclosed to it under this Section 6.2 as confidential information under Section 5.

6.3 Defense of Claims. In the event of the initiation of any suit by a Third Party against Prometheus for patent infringement with respect to the manufacture, use or sale of the Licensed Products, Prometheus shall promptly notify Corixa in writing and Prometheus shall have the right (but not the obligation) to defend any such suit at its own expense and Prometheus shall keep all damages or monetary awards recovered. Corixa shall cooperate and participate as reasonably necessary in any such suit. In the event that Prometheus elects not to defend against a suit related solely to the manufacture, use or sale of Licensed Products, Corixa may (but is not obligated to), at its own expense, defend such suit. Corixa shall be entitled to keep any damages or monetary award recovered by Corixa. Whichever party defends such suit shall keep the other Party reasonably informed of developments with respect thereto. If a Party does not agree in writing with any settlement effected by the other Party, the non-consenting Party shall not be required to pay any amount of such settlement and instead shall have the right (if applicable) to

continue to maintain such suit against such Third Party at its own expense solely with respect to its rights under this Agreement.

6.4 Infringement. In the event that Prometheus becomes aware of actual or threatened infringement or misappropriation of a Licensed Patent or Licensed Materials based on the manufacture, use or sale by a Third Party of a Licensed Product, Prometheus shall promptly notify Corixa in writing. Prometheus shall have the right (but not the obligation) to bring any action relating to an actual or threatened infringement or misappropriation of a Licensed Patent or Licensed Materials based on the manufacture, use or sale by a Third Party of a Licensed Product, at its own expense, and Prometheus shall keep all damages or monetary awards recovered. Corixa shall cooperate and participate as reasonably necessary in any such suit. In the event that Prometheus elects not to bring a suit related to such actual or threatened infringement or misappropriation solely of the Licensed Patents or Licensed Materials, Corixa may, at its own expense, bring such suit; provided, however, that if Prometheus has, on a commercially reasonable basis, elected not to bring such suit, Corixa agrees that it will not bring suit. In the event Corixa does bring suit for infringement or misappropriation, Corixa shall be entitled to keep any damages or monetary award recovered by Corixa. The Parties shall keep one another informed of the status of their respective activities regarding any litigation or settlement concerning any suit under this Section 6.4.

6.5 CORIXA MAKES NO REPRESENTATIONS OR WARRANTIES, EXPRESS OR IMPLIED, OTHER THAN THOSE EXPRESSLY SET FORTH IN SECTION 9 BELOW, WITH RESPECT TO THE LICENSED PATENTS, LICENSED PRODUCTS OR LICENSED MATERIALS, INCLUDING ANY WARRANTY OF NONINFRINGEMENT, PATENTABILITY, MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE.

SECTION 7
TERM AND TERMINATION

7.1 Term. This Agreement shall commence upon the Effective Date and shall remain in effect until expiration of the Royalty Term unless it is earlier terminated in accordance with this Section 7 (the "Term").

7.2 Termination for Material Breach. Failure by a Party (the "Breaching Party") to comply with any of its material obligations contained herein (a "Default") shall entitle the Party that is not in Default (the "Terminating Party") to terminate this Agreement as provided for in this Section 7. Upon a Default, the Terminating Party shall give notice to the Breaching Party specifying the nature of the Default, demanding that it cure such Default, and stating its intention to terminate this Agreement if such Default is not cured. If such Default is not cured within sixty (60) days after the receipt of such notice or thirty (30) days after the receipt of such notice in the case of nonpayment, then the Terminating Party shall be entitled, without prejudice to any other rights conferred on it by this Agreement, and in addition to any other remedies available to it by law or in equity, to terminate this Agreement; provided, however, that any right to terminate this Agreement shall be stayed in the event that, during such thirty (30) day period, the Breaching Party shall have initiated dispute resolution in accordance with Section 10.6 hereof with respect to the alleged Default.

7.3 Consequences of Termination for Prometheus Default. Upon a termination of this Agreement by Corixa because of a Default by Prometheus, subject to the notice and cure provisions set forth in Section 7.2 above, all rights, licenses and options confirmed or granted to Prometheus hereunder shall automatically terminate, free and clear of any obligation to Prometheus under this Agreement, except for the obligations of both Parties under Sections 5 and 8. Notwithstanding any termination or expiration of this Agreement, each sublicense granted by Prometheus under Section 2 shall remain in force so long as the respective Sublicensee fulfills its payment obligations as specified in the applicable sublicense agreement.

7.4 Termination by Prometheus. At any time after Prometheus has paid Corixa the license fee pursuant to Section 3.1, Prometheus shall have the right to terminate this Agreement upon prior notice to Corixa, which termination shall be in writing and shall be effective sixty (60) days following the date of such written notice.

7.5 Termination Upon Insolvency. This Agreement may be terminated by either Party upon notice to the other Party should such other Party: (a) consent to the appointment of a receiver or a general assignment for the benefit of creditors, or (b) file or consent to the filing of a petition under any bankruptcy or insolvency law or have any such petition filed against it which has not been stayed within sixty (60) days of such filing.

7.6 Rights in Bankruptcy. All rights and licenses granted under or pursuant to this Agreement are, and shall otherwise be deemed to be, for purposes of Section 365(n) of the U.S. Bankruptcy Code, licenses of right to "intellectual property" as defined under Section 101 of the U.S. Bankruptcy Code.

7.7 Accrued Rights; Surviving Obligations. Termination of this Agreement for any reason shall be without prejudice to any rights that shall have accrued to the benefit of a Party prior to or on account of such termination. All remedies provided hereunder or elsewhere are cumulative. Sections 3.11, 5, 6.1, 6.5, 7.3, 8, 9 and 10 of this Agreement shall survive the termination of this Agreement for any reason and, Section 1 hereof shall survive such termination to the extent any terms defined therein are used in such other surviving provisions.

SECTION 8
INSURANCE; INDEMNITY

8.1 Insurance. Prometheus shall maintain in full force and effect professional liability insurance coverage with terms comparable to that maintained by other similarly situated biomedical companies engaged in similar diagnostic and development activities at such time as a Licensed Product is being commercially distributed or sold. Prometheus shall maintain such comprehensive professional liability insurance during the period that any Licensed Product is being commercially distributed or sold by Prometheus or its Sublicensee(s) prior to the termination of this agreement, and for an additional period of one (1) year thereafter. The amounts of insurance coverage required under this Section 8.1 shall not be construed to create a limit of Prometheus's liability with respect to its indemnification obligation under Section 8 or under any other provision of this Agreement.

8.2 Indemnification. Subject to Section 8.3 below, from and after the Effective Date, except as otherwise herein specifically provided, each of the Parties hereto shall defend, indemnify and hold harmless the other Party and its successors and assigns, and their respective officers, directors, shareholders, partners and employees from and against all losses, damage, liability and expense including legal fees (but excluding punitive or consequential damages (including lost profits)) ("Losses") incurred thereby or caused thereto arising out of or relating to (i) any breach or violation of, or failure to properly perform, any covenant or agreement made by such Indemnifying Party (as defined in Section 8.3) in this Agreement, unless waived in writing by the Indemnified Party (as defined in Section 8.3); (ii) any breach of any of the representations or warranties made by such Indemnifying Party in this Agreement; or (iii) the gross negligence or willful misconduct of the Indemnifying Party.

8.3 Indemnification Procedure. If either Corixa or Prometheus (in each case an "Indemnified Party") receives any written claim which it believes is the subject of indemnity hereunder by either Prometheus or Corixa, as the case may be (in each case an "Indemnifying Party") the Indemnified Party shall, as soon as reasonably practicable after forming such belief, give notice thereof to the Indemnifying Party, including full particulars of such claim to the extent known to the Indemnified Party; provided, however, that the failure to give timely notice to the Indemnifying Party as contemplated hereby shall not release the Indemnifying Party from any liability to the Indemnified Party, unless such failure to provide timely notice is prejudicial to the Indemnifying Party. The Indemnifying Party shall have the right, by prompt notice to the Indemnified Party, to assume the defense of such claim with counsel reasonably satisfactory to the Indemnified Party, and at the cost of the Indemnifying Party. If the Indemnifying Party does not so assume the defense of such claim, the Indemnified Party may assume such defense with counsel of its choice at the sole expense of the Indemnifying Party.
