All information disclosed by CELL GENESYS or TKT pursuant to the Binding Letter of Intent dated April 21, 2002 (the "LOI") shall be deemed Proprietary Information of CELL GENESYS or TKT, as the case may be, and shall be subject to the terms of this Article 3. For purposes of clarity, it is the intent of the Parties that general financial terms may be disclosed but that the number of Licensed Products and the nature and category of proteins which may be designated under this Agreement , as well as the nature of the milestones herein shall be considered Proprietary Information of both Parties. The identity of the Licensed Products and Designated Proteins shall be TKT Proprietary Information. However, the foregoing obligations shall not apply to particular Proprietary Information solely to the extent that the receiving Party can demonstrate with written evidence that such information:

  1. is known by the Receiving Party at the time of its receipt, and not through a prior confidential disclosure by or on behalf of the Disclosing Party;

  2. is properly in the public domain through no fault of the Receiving Party;

  3. is subsequently disclosed to the receiving Party by a Third Party who may lawfully do so and is not directly or indirectly under an obligation of confidentiality to the Disclosing Party; or

  4. is developed by the Receiving Party independently of, and without reference to or use of, Proprietary Information received from the Disclosing Party.

3.2 Authorized Disclosures. A Party may disclose the Proprietary Information of the other Party to the extent such disclosure:

  1. is required to be disclosed by any governmental or other regulatory agency in order to obtain patents, to obtain approval to conduct clinical trials or to market a Licensed Product; provided, however, that (i) prior written notice is promptly delivered to the disclosing Party in order to provide an opportunity to challenge or limit the disclosure obligations, (ii) such disclosure may be only to the extent necessary to obtain such patents or approval, or to comply with regulations as appropriate and (iii) confidential treatment shall be sought to the extent reasonably practicable;

  2. is necessary to be disclosed to employees, agents, consultants and/or other Third Parties for purposes related to the development and commercialization of Licensed Products (or for such Third Parties to determine their interest in performing such activities) in accordance with this Agreement on the condition that such Third Parties agree to be bound by confidentiality obligations at least as restrictive as the terms herein; or

3.3 Press Releases. Neither Party shall issue a press release relating to this Agreement without the prior review and written consent of the other Party.

3.4 Confidential Treatment. In the event that either Party is required to include this Agreement and any agreements or letters referred to herein in any report, statement or other document filed by such Party with the United States Securities and Exchange Commission (the "SEC"), then the disclosing Party shall [*] to obtain, to the maximum extent permitted by law, confidential treatment from the SEC of any trade secrets and commercial or financial information of a privileged or confidential nature, including without limitation all information relating to the number or identity of the Designated Proteins under this Agreement and the specific financial terms and the nature of the milestones herein, and shall notify the other Party as to such efforts and all related communications with the SEC. Notwithstanding the foregoing, neither Party shall submit a confidentiality request for this Agreement or the agreements or letters referred to herein without providing the other Party with an opportunity for prior review and comment on such confidentiality request. The filing Party shall reasonably consider and attempt to accommodate any such comments by such other Party in submitting such confidentiality request.

  1. Promptly after receipt by any indemnified person of a written notice of a claim or the beginning of any action in respect of which indemnity is to be sought against an indemnifying person pursuant to this Section 8.3, such indemnified person shall notify the indemnifying person in writing of such claim or of the commencement of such action, and, subject to the provisions hereinafter stated, in case any such action shall be brought against an indemnified person and such indemnifying person shall have been notified thereof, such indemnifying person shall be entitled to participate therein, and, to the extent it shall wish, to assume the defense thereof, with counsel reasonably satisfactory to such indemnified person. After notice from the indemnifying person to such indemnified person of its election to assume the defense thereof, such indemnifying person shall not be liable to such indemnified person for any legal expenses subsequently incurred by such indemnified person in connection with the defense thereof; provided, however, that if there exists or shall exist a conflict of interest that would make it inappropriate, in the opinion of counsel to the indemnified person, for the same counsel to represent both the indemnified person and such indemnifying person or any affiliate or associate thereof, the indemnified person shall be entitled to retain its own counsel at the expense of such indemnifying person; provided, however, that no indemnifying person shall be responsible for the fees and expenses of more than one separate counsel for all indemnified parties; provided, however, that no person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. No indemnifying party, in the defense of any such claim or litigation shall, except with the consent of each indemnified party, consent to entry of any judgment or enter into any settlement which does not include as an unconditional term thereof the giving by the claimant or plaintiff to such indemnified party of a release from all liability in respect to such claim or litigation. No indemnified party may settle or agree to settle any claim or litigation as to which indemnification may be sought hereunder without the prior written consent of the indemnifying party. Each indemnified party shall furnish such information regarding itself or the claim in question as an indemnifying party may reasonably request in writing as shall be reasonably required in connection with the defense of such claim and litigation resulting therefrom.

  2. If the indemnification provided for in this Section 8.3 is held by a court of competent jurisdiction to be unavailable to an indemnified party with respect to any loss, liability, claim, damage, or expense referred to therein, then the indemnifying party, in lieu of indemnifying such indemnified party hereunder, shall contribute to the amount paid or payable by such indemnified party as a result of such loss, liability, claim, damage, or expense in such proportion as is appropriate to reflect the relative fault of the indemnifying party on the one hand and of the indemnified party on the other in connection with the statements or omissions that resulted in such loss, liability, claim, damage, or expense as well as any other relevant equitable considerations. The relative fault of the indemnifying party and of the indemnified party shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of material fact or the omission to state a material fact relates to information supplied by the indemnifying party or by the indemnified party and the parties' relative intent, knowledge, access to information, and opportunity to correct or prevent such statement or omission; provided, that in no event shall any contribution by CELL GENESYS hereunder exceed the net proceeds received by CELL GENESYS from the sale of the Shares covered by the Registration Statement.
