ARTICLE VIII
SURVIVAL OF REPRESENTATIONS AND WARRANTIES; INDEMNIFICATION

8.1. Survival of Representations and Warranties.

(a) All Buyer and Seller representations and warranties contained in Articles IV and V of this Agreement or any other agreement, schedule, certificate, instrument or other writing delivered by Buyer or Seller in connection with the transactions contemplated by this Agreement shall survive for {*} after the Closing Date (the “Survival Period”). If a party hereto determines that there has been a breach by any other party hereto of any such representation or warranty and notifies the breaching party in writing (such notice an “Indemnity Notice”) reasonably promptly after learning of such breach but in any case within {*} following the expiration of the Survival Period, such representation or warranty and liability therefor shall survive with respect to the breach specified in the Indemnity Notice until such breach has been resolved. If no Indemnity Notice for a particular breach is received by the Indemnifying Party (as hereinafter defined) {*} following the expiration of the Survival Period, then no remedy shall be available to the Indemnified Party (as hereinafter defined) for such breach of representation and warranty. Notwithstanding the foregoing, the representations and warranties of Section 4.10 (Taxes) shall survive until the expiration of the applicable statute of limitations of the underlying Tax liability.

(b) The indemnification provided for in this Article 8 shall be the exclusive remedy for breach of each party’s representations and warranties (but not with respect to the covenants contained in Article VI). Further, the parties agree that: (a) Seller’s total liability under the Acquisition Agreements (including pursuant to Section 8.2 of this Agreement) shall be limited to {*}, and (b) Buyer’s total liability for breach of a representation and warranty in any Acquisition Agreement (including pursuant to Section 8.3 of this agreement) shall be limited to {*}, provided that nothing contained in this Agreement shall preclude the assertion within {*} following the expiration of the Survival Period by Buyer or any of its Affiliates of any cause of action that may exist, not based upon breach of contract, for fraud. {*}.

8.2. Indemnification by Seller. Subject to the provisions of Section 8.4 below, Seller agrees unconditionally to indemnify, defend, and hold Buyer and its Affiliates, and its and their officers, directors and employees, harmless from and against any and all of the following:

(a) Any and all Losses (but, to avoid doubt, subject to Section 8.1) of every kind, nature or description which arise out of or result from or occur as a consequence of: (i) any false, incorrect or misleading representation or warranty or breach thereof made by or on behalf of Seller in this Agreement (including the Exhibits and Schedules hereto) or in any of the Acquisition Agreements; or (ii) any failure by Seller to perform, comply with, or observe any one or more of their covenants, agreements, or obligations contained in any of the Acquisition Agreements other than the Agreement, but excluding in all cases all Assumed Liabilities.

(b) Any and all Losses other than Assumed Liabilities which may at any time or from time to time arise out of or result from or occur as a consequence of any Third Party Claims which arise out of or result from or are a consequence of: (i) Seller’s ownership and use of the Acquired Assets, or the conduct of the Business and the production, provision, or sale by Seller or its Affiliates of the Product, in each case at any time prior to the Closing Date; (ii) any Excluded Liability; (iii) any failure by Seller to comply with the provisions of this Agreement (except to the extent covered by Section 8.2(a)(i)); and (iv) the failure by Seller to discharge any obligations of Seller which were incurred by Seller or its Affiliates or the Business during the period prior to the Closing Date (except for the Assumed Liabilities), including without limitation the following: (A) any audit or investigation or civil, administrative, or criminal proceedings arising as a result of the operation of the Business prior to the Closing Date whether or not Seller or its Affiliates had knowledge thereof as of the Closing Date, (B) any assessments, adjustments or offsets made against Buyer as a result of such an audit or investigation or in connection with the recovery by any Governmental Authority with respect to Seller’s ownership and use of the Acquired Assets or conduct of the Business prior to the Closing Date, or (C) Seller’s failure to obtain any Third Party Consent that it is required to obtain pursuant to the terms of this Agreement, which is not actually waived in writing by Buyer (to avoid doubt, Third Party Consents exclude consents under {*} and

Without limiting the generality of the foregoing provisions of this Section 8.2 with respect to the measurement of damages, Buyer shall have the right, subject to Section 8.1, to be put in the same financial position as it would have been in had the representations and warranties of Seller been true and correct, had each of the covenants of Seller been performed in full, and had Seller paid, discharged, and performed all of its liabilities and obligations. Further, to avoid doubt, nothing in this Section 8.2 is intended to alter in any way, nor shall it be used to interpret, the definitions of Assumed Liability and Excluded Liability.

8.3. Indemnification by Buyer. Subject to the provisions of Section 8.4 below, Buyer agrees unconditionally to indemnify, defend and hold Seller and its Affiliates, and its and their officers, directors and employees, harmless from and against any and all of the following:

(a) Any and all Losses (but, to avoid doubt, subject to Section 8.1) of every kind, nature or description which arise out of or result from or occur as a consequence of: (i) any false, incorrect or misleading representation or warranty or breach thereof made by or on behalf of Buyer in this Agreement (including the Exhibits and Schedules hereto) or in any of the Acquisition Agreements, but excluding all Excluded Liabilities; (ii) any failure by Buyer to perform, comply with, or observe any one or more of its covenants, agreements, or obligations contained in any of the Acquisition Agreements, but excluding all Excluded Liabilities; or (iii) any counterclaim against Seller resulting from the enforcement or attempted enforcement by Buyer of any of the rights included within the scope of the Patents included in the Transferred Intellectual Property.

(b) Any and all Losses which may at any time or from time to time arise out of or result from or occur as a consequence of any Third Party Claims which arise out of or result from or are a consequence of: (i) Buyer’s ownership and use of the Acquired Assets, or the conduct of the Business at any time on or after the Closing Date; (ii) any Assumed Liability; (iii) any failure by Buyer to comply with the provisions of this Agreement; and (iv) the failure by Buyer to discharge any obligations of Buyer which were incurred by Buyer on or after the Closing Date (except for the Excluded Liabilities), including without limitation the following: (A) any audit or investigation or civil, administrative or criminal proceedings arising as a result of Buyer’s conduct of the Business on or after the Closing Date, and (B) any assessments, adjustments or offsets made against Seller as a result of such an audit or investigation or in connection with the recovery by any Governmental Authority or administrative agency with respect to Buyer’s conduct of the Business on or after the Closing Date.

Without limiting the generality of the foregoing provisions of this Section 8.2 with respect to the measurement of damages, Seller shall have the right, subject to Section 8.1, to be put in the same financial position as it would have been in had the representations and warranties of Buyer been true and correct, had each of the covenants of Buyer been performed in full, and had Buyer paid, discharged, and performed all of its liabilities and obligations. Further, to avoid doubt, nothing in this Section 8.3 is intended to alter in any way, nor shall it be used to interpret, the definitions of Assumed Liability and Excluded Liability.

8.4. Indemnification Process. Any party seeking indemnification under this Article VIII (each, an “Indemnified Party”) shall give each party from whom indemnification is being sought (each, an “Indemnifying Party”) notice of any matter which such Indemnified Party has determined has given rise to or could give rise to a right of indemnification under this Agreement, stating the amount of the Loss, if known, and method of computation thereof, and containing a reference to the provisions of this Agreement in respect of which such right of indemnification is claimed or arises. The obligations and liabilities of an Indemnifying Party under this Article VIII with respect to Losses arising from any Third Party Claims which are subject to the indemnification provided for in this Article VIII shall be governed by and contingent upon the following additional terms and conditions:

(a) If any Indemnified Party shall receive notice of any Third Party Claim, the Indemnified Party shall give the Indemnifying Party notice of such Third Party Claim within thirty (30) days of the receipt by the Indemnified Party of such notice; provided, however, that the failure to provide such notice shall not release the Indemnifying Party from any of its obligations under this Article VIII except to the extent the Indemnifying Party is materially prejudiced by such failure.

(b) If the Indemnifying Party acknowledges in writing its obligation to indemnify the Indemnified Party hereunder against any Losses that may result from such Third Party Claim, then the Indemnifying Party shall be entitled to assume and control the defense of such Third Party Claim at its expense and through counsel of its choice if it gives notice of its intention to do so to the Indemnified Party within thirty (30) days of the receipt of such notice from the Indemnified Party; provided, further, however, that if it would be detrimental to the defense of the Indemnified Party for the same counsel to represent both the Indemnified Party and the Indemnifying Party, then the Indemnified Party shall be entitled to retain its own counsel, in each jurisdiction for which the Indemnified Party determines counsel is required, at the expense of the Indemnified Party.

(c) In the event the Indemnifying Party exercises the right to undertake any such defense against any such Third Party Claim as provided above, the Indemnified Party shall cooperate with the Indemnifying Party in such defense and make available to the Indemnifying Party, at the Indemnifying Party’s expense, all witnesses, pertinent records, materials and information in the Indemnified Party’s possession or under the Indemnified Party’s control relating thereto as is reasonably required by the Indemnifying Party. Similarly, in the event the Indemnifying Party declines to take such defense and the Indemnified Party is, directly or indirectly, conducting the defense against any such Third Party Claim, the Indemnifying Party shall cooperate with the Indemnified Party in such defense and make available to the Indemnified Party, at the Indemnifying Party’s expense, all such witnesses, records, materials, and information in the Indemnifying Party’s possession or under the Indemnifying Party’s control relating thereto as is reasonably required by the Indemnified Party.

(d) If the Indemnifying Party shall have failed to assume the defense of any claim in accordance with the provisions of this Article, then the Indemnified Party shall have the absolute right to control the defense of such claim and, if and when it is finally determined that the Indemnified Party is entitled to indemnification from the Indemnifying Party hereunder, the fees and expenses of the Indemnified Party’s counsel shall be borne by the Indemnifying Party and paid by the Indemnifying Party to the Indemnified Party within five (5) business days of written demand therefor, but the Indemnifying Party shall be entitled, at its own expense, to participate in (but not control) such defense.

(e) So long as the Indemnifying Party has assumed and is conducting the defense of the Third Party Claim in accordance with Section 8.4(b) above, (i) the Indemnifying Party shall not consent to the entry of any judgment or enter into any settlement with respect to the Third Party Claim without the prior written consent of the Indemnified Party (not to be withheld unreasonably withheld, conditioned or delayed and not to be withheld at all if the Indemnified Party is completely released from all claims and not required to make any admission of fault or wrongdoing or take any action pursuant to the terms of the settlement), and (ii) the Indemnified Party shall not consent to the entry of any judgment or enter into any settlement with respect to the Third Party Claim without the prior written consent of the Indemnifying Party (not to be withheld unreasonably).

PRESS RELEASE

Avigen Sells Early Stage Research Program in Hemophilia to Baxter

Alameda, CA, December 17, 2008 – Avigen, Inc. (Nasdaq: AVGN), a biopharmaceutical company, announced today that the company has sold the rights to its early stage blood coagulation compound, AV513, to Xxxxxx Healthcare Corporation, a global leader in hemophilia therapy, for $7 million. Baxter acquired all rights to AV513, a compound poised for clinical research that has been shown to improve blood coagulation in preclinical models for hemophilia. Avigen has been developing AV513 as an oral therapy to treat patients with bleeding disorders, including hemophilia A.

“The sale of AV513 is an example of building value in a product that is differentiated from current therapies, and bringing it to a valuation point that generated a positive return on investment,” said Xxxxxxx Xxxxxxx, Ph.D., X.X., Avigen's president and chief executive officer. “Our team identified AV513 as a drug candidate with a novel approach for treating hemophilia and other bleeding disorders, and which offered strong IP potential in a target patient population with an unmet need. Because it was outside our neurology focus, it was our goal to follow a reasonable budget to establish AV513’s value, and then move it to a better-resourced company with the expertise to develop a safe and effective therapy.”

“This technology acquisition supports Xxxxxx’x efforts to research the application of novel technologies that will pioneer the next generation of hemophilia therapies,” said Xxxxxxx Xxxxxxx, M.D., vice president of global BioScience research and development for Baxter.

“Looking ahead, our objective is to identify opportunities that represent significant potential value for patients, while balancing our investment of resources and development risk in order to provide a significant and timely return to shareholders. Along these lines, we are also in the process of partnering AV411, our non-opioid glial-attenuator product for neuropathic pain and drug addiction,” continued Xxxxxxx.

AV513 was first identified in 2004 by Avigen’s vice president of Research and Development, Xxxx Xxxxxxx, Ph.D., and colleagues, seeking an existing molecule with strategic characteristics for providing an alternative delivery approach for hemophilia therapies. Pre-clinical efficacy data in hemophilic mice was first published in 2006 in the medical journal Thrombosis & Haemostasis. Efficacy data from the study of an oral form of AV513 in other hemophilia A preclinical models was published in the journal Blood in 2007. Most recently, an in vitro study on AV513 pro-coagulant efficacy in the donated blood of human hemophilia patients was presented at the American Society of Hemophilia meeting in San Francisco on December 9^th.

About AV513

AV513 is a drug candidate derived from a specific seaweed enriched for a particular type of non-anticoagulant sulfated polysaccharide denoted fucoidan, which has been shown to boost blood coagulation. Laboratory and preclinical studies indicated AV513’s novel mechanism of action might improve the physiological “spark” for normal blood clot initiation by reducing natural anti-coagulation at local sites of bleeding and thereby allows more normal hemostasis, or clotting. Preclinical in vitro and in vivo studies indicate that AV513 has potential stand-alone utility and might act as an adjunctive or supplementary agent to boost clotting efficiency in combination with Factor VIII or Factor IX, the standard treatments for hemophilia A and B, respectively.
