| 11.1 Indemnification by XOMA. XOMA hereby agrees to defend, indemnify and hold harmless Zydus and its Affiliates and their respective directors, officers, employees and agents (each, a “Zydus Indemnitee”) from and against any and all liabilities, expenses and losses, including reasonable legal expenses and attorneys’ fees (collectively, “Losses”), to which any Zydus Indemnitee may become subject as a result of any claim, demand, action or other proceeding by any Third Party to the extent such Losses arise out of: (a) the Development, manufacture, use, handling, storage, sale, disposition or other Commercialization of any Product (including any XOMA Antibody or Zydus IL-2 contained therein) by XOMA or its Affiliates or Sublicensees; (b) the negligence or willful misconduct of any XOMA Indemnitee; or (c) the breach by XOMA of any warranty, representation, covenant or agreement made by XOMA in this Agreement; except, in each case, to the extent such Losses arise out of the negligence or willful misconduct of any Zydus Indemnitee or the breach by Zydus of any warranty, representation, covenant or agreement made by Zydus in this Agreement.

| 11.2 Indemnification by Zydus. Zydus hereby agrees to defend, indemnify and hold harmless XOMA and its Affiliates and their respective directors, officers, employees and agents (each, a “XOMA Indemnitee”) from and against any and all Losses to which any XOMA Indemnitee may become subject as a result of any claim, demand, action or other proceeding by any Third Party to the extent such Losses arise out of: (a) the Development, manufacture, use, handling, storage, sale, disposition or other Commercialization of any Product (including any XOMA Antibody or Zydus IL-2 contained therein) by Zydus or its Affiliates or Sublicensees; (b) the negligence or willful misconduct of any Zydus Indemnitee, or (c) the breach by Zydus of any warranty, representation, covenant or agreement made by Zydus in this Agreement; except, in each case, to the extent such Losses arise out of the negligence or willful misconduct of any XOMA Indemnitee or the breach by XOMA of any warranty, representation, covenant or agreement made by XOMA in this Agreement.

| 11.3 Procedure. A party that intends to claim indemnification under this Article ‎11 (the “Indemnitee”) shall promptly notify the indemnifying Party (the “Indemnitor”) in writing of any Third Party claim, demand, action or other proceeding (each, a “Claim”) in respect of which the Indemnitee intends to claim such indemnification, and the Indemnitor shall have sole control of the defense or settlement thereof. The Indemnitee may participate at its expense in the Indemnitor’s defense of and settlement negotiations for any Claim with counsel of the Indemnitee’s own selection. The indemnity arrangement in this Article ‎11 shall not apply to amounts paid in settlement of any action with respect to a Claim, if such settlement is effected without the consent of the Indemnitor, which consent shall not be withheld or delayed unreasonably. The failure to deliver written notice to the Indemnitor within a reasonable time after the commencement of any action with respect to a Third Party Claim shall only relieve the Indemnitor of its indemnification obligations under this Article ‎11 if and to the extent the Indemnitor is actually prejudiced thereby. The Indemnitee shall cooperate fully with the Indemnitor and its legal representatives in the investigation of any action with respect to a Claim covered by this indemnification.

The foregoing shall include transferring, upon request of XOMA, any agreements with Third Party suppliers or vendors that specifically cover the supply or sale of any Product (or XOMA Antibody or Zydus IL-2 therein) for the Zydus Territory; provided that if any such contract between Zydus and a Third Party is not assignable to XOMA (whether by such contract’s terms or because such contract does not relate specifically to any Product) but is otherwise reasonably necessary or useful for XOMA to commence Developing, manufacturing or Commercializing Products in the Zydus Territory, or if Zydus or its Affiliate manufactures any Product (or XOMA Antibody or Zydus IL-2 therein) itself (and thus there is no contract to assign), then Zydus shall reasonably cooperate with XOMA to negotiate for the continuation of services or supply from such entity, or Zydus shall supply such XOMA Antibody or Product, as applicable, to XOMA for a reasonable period (not to exceed [*] months) until XOMA establishes an alternate, validated source of such services or supply of finished, packaged, labeled Product for the Zydus Territory. XOMA shall pay Zydus for such supply from Zydus at a price equal to [*]. Zydus shall provide such assistance at no cost to XOMA.

| (ii) Regulatory Filings. The Non-Terminating Party hereby grants, effective upon such termination, an irrevocable right of reference (and shall cause to such right of reference to be granted) to the Terminating Party or its designee all Regulatory Filings (including Regulatory Approvals) for the Products, whether held in the name of the Non-Terminating Party or its Affiliate or Sublicensee, for Products in the Terminating Party’s Territory. The Non-Terminating Party shall take such other actions and execute such other instruments, assignments and documents as may be necessary to effect, evidence, register and record the conveyance of rights under this subsection (ii) to the Terminating Party.

| (iii) Technology Licenses. The Non-Terminating Party hereby grants to the Terminating Party, effective upon the effective date of such termination, a non-exclusive, perpetual, irrevocable, fully paid-up, worldwide license, with the right to sublicense through multiple tiers of sublicensees, under (A) the Zydus Technology (if Zydus is the Non-Terminating Party) or the XOMA Technology (if XOMA is the Non-Terminating Party) and (B) the Non-Terminating Party’s interest in the Collaboration Technology, in each case to Develop, use, make, have made, sell, offer for sale and import Products in the Field. For clarity, the foregoing license includes the rights to make and have made XOMA Antibodies and Zydus IL-2 solely for purposes of Development and Commercialization of Products in the Field.

Upon expiration or termination of this Agreement, except to the extent that a Party obtains or retains the right to use the other Party’s Confidential Information, each Party shall promptly return to the other Party, or delete or destroy, all relevant records and materials in such Party’s possession or control containing Confidential Information of the other Party; provided that such Party may keep one (1) copy of such materials for archival purposes only subject to continuing confidentiality obligations.

| 13.8 Survival. Expiration or termination of this Agreement shall not relieve the Parties of any obligation or right accruing prior to such expiration or termination.

For clarity, in the event of a Party’s material breach of this Agreement, the other Party may elect to retain this Agreement in full force and effect and seek such remedies for such Party’s breach as are available at law or equity.
