(c) [*] 16 5.5 Third Party Licenses. Baxter shall provide XOMA Ireland with sales reports sufficient for XOMA Ireland to prepare all royalty reports due under the Existing Licenses. If Baxter or XOMA Ireland determine in good faith that it is commercially reasonable to acquire intellectual property rights of Third Parties, or licenses thereof, in order to further the marketing and sale of Products by Baxter, the parties shall consider such acquisition or license. ARTICLE 6. INFRINGEMENT ACTIONS BY THIRD PARTIES If any of Baxter, XOMA Ireland or their respective Affiliates or sublicensees is sued by a Third Party for infringement of a Third Party's patent because of the manufacture, use or sale of a Product, the party which has been sued shall promptly notify the other party in writing of the institution of such suit. Baxter shall have the right, in its sole discretion, to control the defense of such suit at its own expense, in which event XOMA Ireland shall have the right to be represented by advisory counsel of its own selection, at its own expense, and shall cooperate fully in the defense of such suit and furnish to the Baxter entity controlling such legal proceedings all evidence in its control and commercially reasonable assistance. If Baxter does not elect within thirty days after receipt of such notice to so control the defense of such suit, XOMA Ireland may undertake such control at its own expense, and Baxter shall then have the right to be represented by advisory counsel of its own selection and at its own expense, and Baxter shall cooperate fully in the defense of such suit and furnish to XOMA Ireland all evidence in its control and commercially reasonable assistance. If XOMA Ireland does not elect within sixty days after receipt of such notice to so control the defense of such suit, Baxter shall be obligated to undertake such control at its own expense, and XOMA Ireland shall again have the right to be represented by advisory counsel of its own selection and at its own expense, and XOMA Ireland shall cooperate fully in the defense of such suit and furnish to Baxter all evidence in its control and commercially reasonable assistance. Upon any termination of this Agreement, XOMA Ireland may undertake such control at its own expense, and Baxter shall cooperate fully in the defense of such suit and furnish to XOMA Ireland all evidence in its control and commercially reasonable assistance. Each party shall, in good faith, consider the advice of the other party in connection with any such action. The party controlling the suit may not settle the suit or otherwise consent to an adverse judgment in such suit that diminishes the rights or interests of the non-controlling party without the express written consent of the non-controlling party (which consent shall not be unreasonably withheld or delayed).

For a period of ninety days after the [*] Notice, the parties shall in good faith negotiate the terms of a corporate partnering, licensing or other transaction (an "Baxter [*] Transaction"); provided, however, that if at any time Baxter does not in good faith intend to pursue a Baxter [*] Transaction, Baxter shall notify XOMA Ireland of such fact within ten days of the date such decision is made by Baxter. With respect to such products in the Field, if the parties in good faith cannot agree on the terms of an Baxter [*] Transaction within the ninety day period set forth above, or Baxter notifies XOMA Ireland that it does not intend to pursue such a transaction, XOMA Ireland shall be entitled to enter into an [*] Third Party Transaction with any Third Party. 18 ARTICLE 8.

To the extent it is reasonably necessary or appropriate to fulfill its obligations or exercise its rights under this Agreement, (a) a party may disclose Information it is otherwise obligated under this Article 8 not to disclose to its Affiliates, sublicensees, consultants, outside contractors and clinical investigators, on a need-to-know basis, provided that each such Person agrees to keep the Information confidential and not use the Information for the same time periods and to the same extent as such party is required; and (b) a party may disclose such Information to government or other regulatory authorities to the extent that such disclosure is required by applicable law, regulation or court order, or is reasonably necessary to obtain patents or authorizations to conduct Clinical Trials with, and to commercially market, Products, provided that the disclosing party shall provide written notice to the other party and sufficient opportunity to object to such disclosure or to request confidential treatment thereof. 8.3 Exceptions. The obligation not to disclose or use Information shall not apply to any part of such Information that (a) is or becomes patented, published or otherwise part of the public domain other than by acts of the party obligated not to disclose such Information or its Affiliates or sublicensees in contravention of this Agreement; (b) is disclosed to the receiving party or its Affiliates or sublicensees by a Third Party, provided such Information was not obtained by such Third Party directly or indirectly from the other party under this Agreement on a confidential basis; (c) prior to disclosure under this Agreement, was already in the possession of the receiving party or its Affiliates or sublicensees, provided such Information was not obtained directly or indirectly from the other party under this Agreement; or (d) is disclosed in a press release agreed to by both parties, which agreement shall not be unreasonably withheld. 8.4 Terms of this Agreement. Baxter and XOMA Ireland shall not disclose the existence of or any terms or conditions of this Agreement to any Third Party without the prior consent of the other party, except and only to the extent required by applicable law, regulation, court order or the Existing Licenses; provided that the disclosing party shall provide written notice to the other party and sufficient opportunity to object to such disclosure or to request confidential treatment thereof.

XOMA Ireland shall use its commercially reasonable good faith efforts to have such costs shared by other persons with a license to such patents in fields other than the Field. Each party shall make available to the other party or its authorized attorneys, agents or representatives, its employees, agents or consultants necessary or appropriate to enable the appropriate party to file, prosecute and maintain patent applications and resulting patents with respect to Improvements and Inventions for a period of time sufficient for such party to obtain the assistance it needs from such personnel. Each applicable party shall sign or cause to have signed all documents relating to said patent applications or patents at no charge to the other. 9.2 Enforcement of Patent Rights. XOMA Ireland shall have the right to determine the appropriate course of action, after reasonable consultation with Baxter, to enforce the Patents or otherwise abate the infringement thereof, to take (or refrain from taking) appropriate action to enforce the patents, to control any litigation or other enforcement action and to enter into, or permit, the settlement of any such litigation or other enforcement action with respect to the Patents, and in good faith shall consider the interests of Baxter, if any, in so doing. The parties shall fully cooperate with each other in any action to enforce the Patents, and Baxter shall reimburse XOMA Ireland for all costs incurred under this Section 9.2. All monies recovered upon the final judgment or settlement of any suit to enforce the Patents shall first be paid to recover the respective actual out-of-pocket expenses of the parties associated with the enforcement, and thereafter [*] 20 9.3 Ownership of Inventions. The entire right and title in all XOMA Inventions, and any patent applications or patents based thereon, shall be owned solely by XOMA Ireland. The entire right and title in all Baxter Inventions, and any patent applications or patents based thereon, shall be owned solely by Baxter. The entire right and title in all Joint Inventions, and any patent applications or patents based thereon, shall be owned jointly by XOMA Ireland and Baxter.

XOMA Ireland and Baxter each hereby represents that all employees and other Persons acting on its behalf in performing its obligations under this Agreement shall be obligated under a binding written agreement to assign or license to it, or as it shall direct, all Inventions made or developed by such employees or other Persons. 9.4 Notification of Patent Term Restoration. Each party or its Affiliates shall notify the other party of (a) the issuance of each United States patent included within the Patents, giving the date of issue and patent number for each such patent, and (b) each notice pertaining to any patent included within the Patents which it receives as patent owner pursuant to the Drug Price Competition and Patent Term Restoration Act of 1984 (the "Act"), including notices pursuant to Sections 101 and 103 of the Act from persons who have filed an abbreviated new drug application. Such notices shall be given promptly, but in any event within five days of each such patent's date of issue or receipt of each such notice pursuant to the Act, whichever is applicable. Each party or its Affiliates shall notify the other party of each filing for patent term restoration under the Act, any allegations of failure to show due diligence and all awards of patent term restoration (extensions) with respect to the Patents. Likewise, each party or its Affiliates shall inform the other party of patent extensions and periods of data exclusivity in the rest of the world relating to Products. ARTICLE 10. INDEMNIFICATION AND INSURANCE 10.1 Indemnification by Baxter. Baxter agrees to defend, indemnify and hold harmless XOMA Ireland, its agents and employees, against claims for loss, liability, damage and costs (including reasonable fees of counsel, claims for personal injury or the costs of recalls) attributable to the actions or omissions, if any, of Baxter or its subcontractors in the manufacturing (to the extent Baxter or its subcontractors manufacture), packaging, labeling, marketing, use or sale (subject to XOMA Ireland's obligations under Section 10.2) of any Product. 10.2 Indemnification by XOMA Ireland. XOMA Ireland agrees to defend, indemnify and hold harmless Baxter, its agents and employees, against claims for loss, liability, damage and costs (including reasonable fees of counsel, claims for personal injury or the costs of recalls) attributable to the actions or omissions, if any, of XOMA Ireland or its subcontractors in the designing, manufacturing (to the extent XOMA Ireland or its subcontractors manufacture), packaging, labeling, marketing, use or sale (subject to Baxter's obligations under Section 10.1) of any Product. 21 10.3 Procedure. A party (the "Indemnitee") that intends to claim indemnification under this Article 10 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 10 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 any liability to the Indemnitee under this Article 10 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 10. 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. 10.4 Insurance. Baxter and XOMA Ireland each shall obtain liability insurance (but each party may self insure to the extent reasonable given the financial position of the 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 Ireland intends to increase its insurance in connection with the commencement of commercial sales of Product. Baxter and XOMA Ireland 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 Ireland 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 Ireland 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 insurance covering the development, manufacture and sale of similar products. Upon request, XOMA Ireland shall furnish to Baxter a certificate of insurance evidencing such insurance. Upon request, XOMA Ireland 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 Ireland's insurance but shall be entitled to coverage under such policies to the extent of any loss arising out of this Agreement. If XOMA Ireland shall obtain coverage in excess of the self insured loss limits retained by Baxter, Baxter shall name XOMA Ireland as an additional insured under Baxter's insurance policies insuring excess losses over Baxter's self insurance program up to the loss limits then held by XOMA Ireland, but XOMA Ireland 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. 22 ARTICLE 11. CHANGE OF CONTROL If the board of directors of XOMA Ireland Limited or its parent intends to enter into one or more agreements or take any other actions which could reasonably be expected to result in a Change of Control, XOMA Ireland shall, or cause its Affiliates to provide Baxter with an opportunity to make an offer to purchase XOMA Ireland Limited or its parent. Baxter shall have ten business days from the receipt of notice from XOMA Ireland Limited of such intended agreements or actions to make an offer to acquire XOMA Ireland Limited or its parent, as applicable. The applicable board of directors shall in good faith, subject to their fiduciary duties under applicable law, consider such offer. ARTICLE 12. TERM AND TERMINATION 12.1 Termination for Cause.

The provisions of Articles 8, 9, 11 and 12 and Sections 13.3, 13.5, 13.7.1 and 13.9-13.12 shall survive the expiration or termination of this Agreement. 12.4.2.

If the parties are unable to reach agreement in such ten-day period, then the parties shall refer such dispute to a single third party arbitrator selected by the Center for Public Resources (the "CPR") in accordance with its rules. In accordance with the rules of the CPR, such arbitrator shall consider all relevant facts and circumstances and based thereon conclusively determine an equitable allocation of rights to specific indications within the Field, compensation for investments in Products in the Field and future royalties, if any. Such arbital decision shall be binding on the parties and may be confirmed by court order under the Federal Arbitration Act, as amended. The cost of such arbitration shall be borne in accordance with the rules of the CPR. 12.5 Term.
