XOMA US agrees to defend, indemnify and hold harmless Baxter, its agents and employees, against claims for loss, liability, damage and costs (including, but not limited to, reasonable fees of counsel, claims for personal injury or costs of recalls) (a) attributable to the actions or omissions, if any, of XOMA US or its subcontractors in designing, manufacturing (to the extent XOMA US or its subcontractors manufacture), packaging, labeling, marketing, use or sale of any Product (subject to Baxter's obligations under Section 7.1) or (b) resulting from the failure of such Product to conform to the warranties set forth herein. Baxter shall not be deemed to be a subcontractor of XOMA US for purposes of this Article 7. 7.3 Procedure. A party (the "Indemnitee") that intends to claim indemnification under this Article 7 shall promptly notify the other party (the "Indemnitor") of any liability or action in respect of which the Indemnitee intends to claim such indemnification, and the Indemnitor shall have the right to participate in, and, to the extent the Indemnitor so desires, jointly with any other Indemnitor similarly noticed, to assume the defense thereof with counsel selected by the Indemnitor; provided, however, that an Indemnitee shall have the right to retain its own counsel, with the fees and expenses to be paid by the Indemnitor, if representation of such Indemnitee by the counsel retained by the Indemnitor would be inappropriate due to actual or potential differing interests between such Indemnitee and any other party represented by such counsel in such proceedings and shall have the right to retain its own counsel at its own expense for any reason (subject to the Indemnitor's right to control such defense). The indemnity obligations under this Article 7 shall not apply to amounts paid in settlement of any loss, claim, damage, liability or action if such settlement is effected without the consent of the Indemnitor, which consent shall not be withheld unreasonably. The failure to deliver notice to the Indemnitor within a reasonable time after the commencement of any such action shall relieve such Indemnitor of liability to the Indemnitee under this Article 7 to the extent such failure is prejudicial to its ability to defend such action, but the omission so to deliver notice to the Indemnitor will not relieve it of any liability that it may have to any Indemnitee otherwise than under this Article 7. The Indemnitee, its employees and agents, shall cooperate fully with the Indemnitor and its legal representatives in the investigation of any action, claim or liability covered by this indemnification. 7.4 Insurance. Baxter and XOMA US each shall obtain liability insurance (but each party may self-insure to the extent reasonable given the financial position of such party and its parent), with respect to its activities contemplated by this Agreement in such amounts as are customary for biopharmaceutical companies engaged in similar activities. XOMA US intends to increase its insurance coverage in connection with the commencement of commercial sales of Product. Baxter and XOMA US each shall maintain such insurance (or self insurance in the case of Baxter) for so long as each continues to conduct such activities, and thereafter for so long as each customarily maintains insurance for itself covering similar activities. XOMA US has obtained product liability insurance with respect to the development, manufacture and sale of such Product in such amounts as are customary for biopharmaceutical companies engaged in the development, manufacture and sale of similar products. XOMA US shall maintain such product liability insurance for so long as it continues to develop, manufacture and sell such Product, and thereafter for so long as companies in the biopharmaceutical business customarily maintain 15 insurance covering the development, manufacture and sale of similar products. Upon request, XOMA US shall furnish to Baxter a certificate of insurance evidencing such insurance. Upon request, XOMA US shall cause Baxter to be named an additional insured under such policy within thirty days of such request, but Baxter shall not have the right to control XOMA US' insurance but shall be entitled to coverage under such policies to the extent of an loss arising out of this Agreement. If XOMA US shall obtain coverage in excess of the self insured loss limits retained by Baxter, Baxter shall name XOMA US as an additional insured under Baxter's insurance policies insuring losses over Baxter's self-insurance program up to the loss limits then held by XOMA US, but XOMA US shall not have the right to control Baxter's insurance but shall be entitled to coverage under such policies to the extent of any insured loss arising out of this Agreement. ARTICLE 8. TERM OF AGREEMENT 8.1 Termination of Supply Obligations. The parties obligations under Section 2.1 of this Agreement shall continue in full force and effect for the time commencing with the Effective Date and continuing until the third anniversary of the Effective Date. Thereafter, the parties obligations under Section 2.1 of this Agreement may be extended, at Baxter's option, after consideration by Baxter of XOMA US' manufacturing capacity, including the "XOMA V" facility, upon twelve months prior notice, for successive one year periods. 8.2 Other Termination Events.

Except as provided in Section 8.1, either party shall have the right to terminate this Agreement if the License Agreement shall have been rightfully terminated; provided, that such termination shall be effective with respect to the non-terminating party's rights under this Agreement only to the extent commercially consistent with any retained rights or settlement under the License Agreement. This Agreement shall also terminate if a portion of the License Agreement is terminated pursuant to Section 12.5 of the License Agreement. 8.4 Effect of Expiration and Termination.

Baxter shall have ten business days from the receipt of notice from XOMA (US) LLC of such intended agreements or actions to make an offer to acquire XOMA (US) LLC or its parent, as applicable.
