If LICENSEE notifies UTMDACC that it does not intend to pay the cost of an application, or if LICENSEE does not respond or make an effort to agree with UTMDACC on the disposition of rights of the subject invention, then UTMDACC may file such application at its own expense and LICENSEE’s rights to such invention under this AGREEMENT shall terminate in their entirety. The parties agree that they share a common legal interest to get valid enforceable patents and that LICENSEE will keep all privileged information received pursuant to this Section confidential.

VII. INFRINGEMENT BY THIRD PARTIES

7.1

LICENSEE, at its expense, must enforce any patent exclusively licensed hereunder against infringement by third parties and is entitled to retain recovery from such enforcement. After reimbursement of LICENSEE’s reasonable legal costs and expenses related to such recovery, LICENSEE agrees to pay UTMDACC either: (a) the royalty detailed in Section 4.1(d) for any monetary recovery that is for sales of LICENSED PRODUCTS lost due to the infringement and fifty percent (50%) of punitive damages for willful infringement; or (b) fifty percent (50%) of reasonable royalties awarded and

punitive damages for willful infringement in any recovery in which the award is for reasonable royalties. LICENSEE must notify UTMDACC in writing of any potential infringement within thirty (30) calendar days of knowledge thereof. If LICENSEE decides not to pursue an infringement enforcement action within six month of knowledge of such infringement, LICENSEE will notify UTMDACC and then BOARD or UTMDACC may, at its discretion, after considering the commercially reasonable bases for LICENSEE’s decision not to pursue such infringement enforcement action, pursue the enforcement of any patent licensed hereunder on behalf of itself and LICENSEE. In such case, the parties will discuss in good faith the appropriate settlement of such case and/or the appropriate distribution of any recovery from such action, which shall depend on LICENSEE’s involvement and effect of the LICENSEE’s ability to commercialize the LICENSED SUBJECT MATTER.

7.2

In any suit or dispute involving an infringer, the parties agree to cooperate fully with each other. At the request and expense of the party bringing suit, the other party will permit access during regular business hours, to all relevant personnel, records, papers, information, samples, specimens, and the like in its possession.

VIII. PATENT MARKING

8.1

LICENSEE agrees that all packaging containing individual LICENSED PRODUCT(S), documentation therefor, and when possible for actual LICENSED PRODUCT(S) sold by LICENSEE, AFFILIATES, and/or sublicensees of LICENSEE will be permanently and legibly marked with the number of any applicable patent(s) licensed hereunder in accordance with each country's patent laws, including Xxxxx 00, Xxxxxx Xxxxxx Code.

IX. INDEMNIFICATION AND INSURANCE

9.1

LICENSEE agrees to hold harmless and indemnify BOARD, SYSTEM, UTMDACC, its Regents, officers, employees, students and agents from and against any claims, demands, or causes of action whatsoever, costs of suit and reasonable attorney’s fees, including without limitation, those costs arising on account of any injury or death of persons or damage to property caused by, or arising out of, or resulting from, the exercise or practice of the rights granted hereunder by LICENSEE, its officers, its AFFILIATES or their officers, employees, agents or representatives.

9.2

9.3

Beginning at the time when any LICENSED SUBJECT MATTER is being distributed or sold (including for the purpose of obtaining regulatory approvals) by LICENSEE or by a sublicensee, LICENSEE shall, at its sole cost and expense, procure and maintain commercial general liability insurance in amounts not less than $2,000,000 per incident and $2,000,000 annual aggregate, and LICENSEE shall use reasonable efforts to have the BOARD, SYSTEM, UTMDACC, its Regents, officers, employees, students and agents named as additional insureds. Such commercial general liability insurance shall provide: (i) product liability coverage; (ii) broad form contractual liability coverage for

LICENSEE's indemnification under this AGREEMENT; and (iii) coverage for litigation costs. The minimum amounts of insurance coverage required herein shall not be construed to create a limit of LICENSEE's liability with respect to its indemnification under this AGREEMENT.
