7. INFRINGEMENT

7.1 If Trinity is notified of any patent held by a third party that Trinity reasonably believes would be infringed by the continued Sale
of Licensed Products, or by the use of Licensed Products by its customers, or of the possible infringement by a third party of the Patent Rights granted hereunder, Trinity agrees to promptly notify Board of same in
writing.

7.2 Trinity, at its expense, may enforce any patent licensed hereunder against third party infringement within the Licensed Field
and Licensed Territory, and shall be entitled to retain recoveries from such enforcement. If legally required to do so, Board and University agree to be named parties in any litigation instituted by Trinity to enforce
Patent Rights. Trinity agrees to pay Board a royalty as set forth above on any monetary recovery (after deduction of Trinitys third-party, documented, unrecovered reasonable legal expenses incurred exclusively from
such suit) if the monetary recovery is for damages based on sales of an infringing product or a reasonable royalty in lieu thereof. If Trinity does not file suit against a substantial infringer of a patent within six (6) months of
knowledge thereof, then Board and University, at their sole discretion and expense, may enforce any patent licensed hereunder on behalf of themselves and Trinity, with Board retaining all recoveries from such enforcement.

7.3 In any infringement suit or dispute, 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 to all relevant personnel, records, papers, information, samples, specimens, etc., during regular business hours.

7.4 Trinity may request that Board join the prosecution of an infringer. If Board agrees, then Trinity and Board shall
jointly enforce against infringement by third parties and shall be entitled to retain any recovery from such enforcement. After deducting Trinitys and Boards third-party, documented, unrecovered reasonable legal expenses
incurred exclusively from such suit, any remaining recovery shall be divided equally.

8. ASSIGNMENT

Except in connection with the sale of substantially all of Trinitys assets to a third party, this Agreement may not be assigned by
Trinity without the prior written consent of Board, which will not be unreasonably withheld.

9. PATENT MARKING AND

its Affiliates pursuant to this Agreement with a patent notice as may be permitted or required under Title 35, United States Code, or if such marking is not practicable, shall so mark the accompanying outer box or product insert for
Licensed Productsaccordingly.

10. INDEMNIFICATION

against any claims, demands, or causes of action whatsoever, or costs of suit or 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 license granted hereunder by Trinity, its officers, Affiliates or their officers, employees, agents or representatives.

11. USE OF BOARD AND UNIVERSITY NAME

Trinity may not use the name of University, System, or Board without express written consent.

12. CONFIDENTIAL INFORMATION AND PUBLICATION

12.1 Board and Trinity each agree that all information contained in documents marked confidential and forwarded to one by the other
(i) are to be received in strict confidence, (ii) used only for the purposes of this Agreement, and (iii) not disclosed by the recipient party, its agents or employees without the prior written consent of the other party,
except to the extent that the recipient party can establish competent written proof that such information:



| | a. | was in the public domain at the time of disclosure;
| | -- | ---------------------------------------------------



| | b. | later became part of the public domain through no act or omission of the recipient party, its employees, agents, successors or assigns;
| | -- | ---------------------------------------------------------------------------------------------------------------------------------------



| | c. | was lawfully disclosed to the recipient party by a third party having the right to disclose it;
| | -- | -----------------------------------------------------------------------------------------------



| | d. | was already known by the recipient party at the time of disclosure;
| | -- | -------------------------------------------------------------------



| | e. | was independently developed by the recipient, as evidenced by written documentation; or
| | -- | ---------------------------------------------------------------------------------------



| | f. | is required by law or regulation to be disclosed.
| | -- | -------------------------------------------------

12.2 Each partys obligation of confidence hereunder
shall be fulfilled by using at least the same degree of care with the other partys confidential information as it uses to protect its own confidential information. This obligation shall exist while this Agreement is in force and for a
period of three (3) years thereafter.

13. PATENTS AND INVENTIONS

13.1 If after consultation with Trinity, both parties agree that a patent application should be filed for Licensed Subject Matter, Board
will prepare and file the appropriate patent applications, and Trinity will pay the cost, according to Section 5.1(g) above, of searching, preparing, filing, prosecuting and maintaining same. If Trinity notifies Board that
it does not intend to pay the costs of an application, or if Trinity does not respond or make an effort to agree with Board on the disposition of rights in the subject invention, then Board may file an application at its own
expense and Trinity will have no rights to such invention.

13.2 Board will provide Trinity a copy of any patent application for
which Trinity has paid the costs, according to Section 5.1(g) above, of searching, preparing and filing, as well as copies of any documents received or filed with the respective patent office during the prosecution thereof
(Notice). Should Trinity decline to support a particular patent application in a particular country, Trinity shall so notify the University in writing within thirty (30) days after receiving Notice
and Trinity shall thereafter have no further rights hereunder in that particular patent application in that particular country.

14. ALTERNATE DISPUTE RESOLUTION

Any dispute or controversy arising out of or relating to this Agreement, its construction or its actual or alleged breach may be decided by mediation.
If the mediation does not result in a resolution of such dispute or controversy, it may be decided by an appropriate method of alternate dispute resolution, including without limitation, arbitration, conducted in the city of Houston, Texas in
accordance with the Licensing Agreement Arbitration Rules of the American Arbitration Association. The arbitration panel will include members knowledgeable in the evaluation of protein and antibody-based technologies. Judgment upon the award
rendered may be entered in the highest court or forum having jurisdiction, state or federal. The provisions of this Article 14 will not apply to decisions on the validity of patent claims or to any dispute or controversy as to which any treaty or
law prohibits such arbitration. The decision of the arbitration must be sanctioned by a court of law having jurisdiction to be binding upon and enforceable by the parties. The use of any method of alternative dispute resolution will not be construed
by either party in a manner that would adversely affect the other partys rights in court. Nothing in this section will prevent one party from resorting to judicial proceedings if good faith efforts to resolve a dispute have been unsuccessful
or if injunctive relief is necessary to prevent serious and irreparable harm to one party or third parties.
