ARTICLE V.

SURVIVAL AND INDEMNIFICATION

Section 5.01           Survival All representations and warranties shall survive the consummation of the transaction contemplated hereby and continue until the third anniversary of the Closing Date; notwithstanding the foregoing, any representations and warranties by Valentis concerning the Patents shall continue until expiration of the last to expire Patent.

Section 5.02           Indemnification by Valentis Valentis agrees to indemnify and hold harmless BIOLITEC, its Affiliates and their respective officers, directors, employees, agents, successors and assigns (each, a “BIOLITEC Indemnified Party”) against any and all Liabilities and costs and damages (including amounts paid in settlement and reasonable costs of investigation and legal expenses) as incurred (collectively, “Losses”) arising out of or relating to (a) a breach of any representation, warranty, covenant or agreement of Valentis in this Agreement or any Related Agreement or in any certificate or instrument delivered pursuant hereto or (b) any of the Excluded Liabilities.  The parties agree to treat any indemnity payment by Valentis as a reduction to the Purchase Price.  In the event any such indemnity payment is subject to withholding tax Valentis will pay such additional amounts to BIOLITEC so that net amount received by the BIOLITEC will be the same as it would have been had there been no withholding.  Notwithstanding the foregoing, the indemnification provided for herein shall not apply to the extent that the Losses of a BIOLITEC Indemnified Party are due to such party’s gross negligence, recklessness or willful misconduct.

Section 5.03           Indemnification by BIOLITEC BIOLITEC agrees to indemnify and hold harmless Valentis, its Affiliates and their respective officers, director, employees, agents, successors and assigns (each, a “Valentis Indemnified Party”) against any and all Losses arising out of or related to a breach of any representation, warranty, covenant or agreement of BIOLITEC in this Agreement or any Related Agreement or in any certificate or instrument delivered pursuant hereto.  Notwithstanding the foregoing, the indemnification provided for herein shall not apply to the extent that the Losses of a Valentis Indemnified Party are due to such party’s gross negligence, recklessness or willful misconduct.

Section 5.04           Indemnification Process In the case of any claim asserted by a third party against a party entitled to indemnification under this Agreement (the “Indemnified Party”), notice shall be given by the Indemnified Party to the party required to provide indemnification (the “Indemnifying Party”) promptly after such Indemnified Party has actual knowledge of any claim as to which indemnity may be sought, and the Indemnified Party shall permit the Indemnifying Party (at the expense of such Indemnifying Party) to assume the defense of any claim or any litigation resulting therefrom; provided that (a) the counsel for the Indemnifying Party who shall conduct the defense of such claim or litigation shall be reasonably satisfactory to the Indemnified Party, (b) the Indemnified Party may participate in such defense at such Indemnified Party’s expense, and (c) the omission by any Indemnified Party to give notice as provided herein shall not relieve the Indemnifying Party of its indemnification obligation under this Agreement except to the extent that such omission results in a failure of actual notice to the Indemnifying Party and such Indemnifying Party is materially damaged as a result of such failure to give notice.  Except with the prior written consent of the Indemnified Party, no Indemnifying

11

Party, in the defense of any such claim or litigation, shall consent to entry of any judgment or enter into any settlement that provides for injunctive or other non-monetary relief affecting the Indemnified Party or that does not include as an unconditional term thereof the giving by each claimant or plaintiff to such Indemnified Party of a release from all liability with respect to such claim or litigation.  In the event that the Indemnified Party shall in good faith determine that the conduct of the defense of any claim subject to indemnification hereunder or any proposed settlement of any such claim by the Indemnifying Party might be expected to affect adversely the Indemnified Party’s Tax liability or the ability of BIOLITEC to conduct its business, or that the Indemnified Party may have available to it one or more defenses or counterclaims that are inconsistent with one or more of those that may be available to the Indemnifying Party in respect of such claim or any litigation relating thereto, the Indemnified Party shall have the right at all times to take over and assume control over the defense, settlement, negotiations or litigation relating to any such claim at the sole cost of the Indemnifying Party; provided that if the Indemnified Party does so take over and assume control, the Indemnified Party shall not settle such claim or litigation without the written consent of the Indemnifying Party, such consent not to be unreasonably withheld or delayed. In the event that the Indemnifying Party does not accept the defense of any matter as above provided, the Indemnified Party shall have the full right to defend against any such claim or demand and shall be entitled to settle or agree to pay in full such claim or demand with the written consent of the Indemnifying Party, such consent not to be unreasonably withheld or delayed.  In any event, the Indemnifying Party and the Indemnified Party shall cooperate in the defense of any claim or litigation subject to this Section 5.04 and the records of each shall be available to the other with respect to such defense.
