right to use the name “Board of Regents, The University of Texas System” and “The University of Texas System Cancer Center” to the extent necessary to enforce and protect LICENSEE’s rights hereunder; provided however, that

 C. BOARD and UTSCC hereby grant to LICENSEE the right of access to, during normal business hours, and the use of, all experimental or other data which
relate in any manner to the BOARD Patent Rights or the BOARD Technical Information, including without limitation, all data which BOARD has provided to the United States Patent Office, the Food and Drug Administration (FDA) or any other state,

data, nor do anything else which will adversely affect LICENSEE’s rights under this Agreement in any manner. BOARD and UTSCC shall cooperate fully with
LICENSEE, at LICENSEE’s expense, in order to obtain the regulatory approval of any state, federal, foreign or local authority which now is or later becomes necessary to develop, manufacture, use, market or sell any Licensed Patented Product or
Process or Licensed Non-Patented Product or Process. Such cooperation shall include, but not be limited to, obtaining all necessary regulatory approvals which are now required, or may in the future be required, to manufacture, use, market or sell

activities covered by the BOARD Patent Rights and that cross-licenses between the BOARD (or LICENSEE) and such third parties may be necessary in order to enable LICENSEE to make or market Licensed Patented Products or Processes or Licensed
Non-Patented Products or Processes. In that event, LICENSEE has the right to enter into cross-licensing agreements with third parties and to grant cross-licenses under any or all of the BOARD Patent Rights, provided:

 4. Any money or the value of any equipment, including license issue fees (and not
including proceeds from sale of marketing rights as described in Section IV.A.3.), received by LICENSEE in exchange for such cross-licensing is treated as Net Sales for Licensed Patented Products or Processes or Licensed Non-Patented Products or
Processes. 
 III.

II.B. above in connection with the grant by BOARD to LICENSEE of this license, LICENSEE agrees that, upon execution of this Agreement by BOARD, it shall issue BOARD 400,000 shares of its Common Stock, $.001 par value, which shares of Common Stock

Shares, and completes the purchase of such Shares as required, a proportionate amount of the Common Stock issued to Board in connection with the execution of this License Agreement shall, concurrent with the closing of such purchase of the Shares,
thereupon be returned to LICENSEE by BOARD, in accordance with the schedule attached as Exhibit B hereto, whereupon such shares of Common Stock shall be cancelled and BOARD shall no longer have any right, title or interest therein.

 C. As an alternative to the election by BOARD to purchase the Shares, BOARD may elect to make a contribution to LICENSEE, in an aggregate amount not
exceeding $300,000, said sum to be applied to research and development activities in accordance with the R & D Agreement (as defined hereinafter). In exchange for such contributions, LICENSEE shall issue BOARD up to 600,000 shares of Series A

Series A Preferred Stock shall expire for the corresponding amount of shares for which LICENSEE has not received written notice of BOARD’S election to fund, and BOARD shall have no further right to acquire such shares of Series A Preferred
Stock, unless otherwise extended by agreement of the parties. 
 2. In the event that BOARD does properly elect to contribute
funds to the LICENSEE’s research and development activities, and makes the contribution as required, a proportionate amount of Common Stock issued in connection with the execution of this License Agreement shall, concurrent with such funding,
be returned to LICENSEE by BOARD in accordance with the schedule set out on Exhibit B hereto, whereupon such shares of Common Stock shall be cancelled and BOARD shall no longer have any right, title or interest therein. 
 3. Effective upon the contribution by BOARD of some or all of the funds for research and development, as provided herein, the royalty
obligations of LICENSEE provided for in Sections IV.A.1. and 2. would increase to the applicable percentage amount as provided in the schedule attached hereto as Exhibit B.

 D. The option to purchase Series A Preferred Stock under Section III.B. and to acquire shares of Series A
Preferred Stock under Section III.C. are mutually exclusive and can not be jointly exercised in any form or fashion. 
 E. In consideration
of the granting of the mutually exclusive options by LICENSEE to BOARD as set forth in Sections III.B. and III.C., BOARD hereby consents to the issuance of, and, upon issuance of the Common Stock to it as provided in Section III.A. above, agrees to
vote such shares, if required, in order to authorize and issue, the following securities to the initial round of venture capital firms:

LICENSEE, whichever first occurs, interest to be payable at the closing of the second round of venture capital financing. Such Notes may, at LICENSEE’S option, be redeemed by LICENSEE at any time prior to May 30, 1987, in the principal
amount of all outstanding Notes, or a portion thereof, plus accrued interest. In the event such Notes are not redeemed in whole by LICENSEE, the Notes shall automatically be converted into shares of Series A Preferred Stock, equal to twice the
unredeemed amount of Notes then outstanding, not exceeding 600,000 shares (see Exhibit C attached hereto.) Such Notes shall contain such other terms and conditions as are customary for such transactions. 
 2. Warrants to Purchase Common Stock, at a purchase price of $.10 share, in a total amount of 150,000 shares of Common Stock of LICENSEE,
to be issued to the holders of the LICENSEE’S 8% Convertible Notes, pro rata, which warrants shall only be exercisable in an amount equal to one-half of the principal amount of 8% Convertible Notes of the LICENSEE which are redeemed by LICENSEE
(see Exhibit C attached hereto). 
 F. BOARD acknowledges that The Woodlands Venture Capital Company has been issued 10,000 shares of Common
Stock of LICENSEE in consideration of the payment of $10.00 by it and of the efforts of its employees in establishing LICENSEE, managing it, and negotiating this Agreement. BOARD further acknowledges that LICENSEE has, prior to the effective date
hereof, issued 300,000 shares of Class A Common Stock to each of Gabriel Lopez-Berestein, M.D., and Jim Klostergaard, Ph.D., in exchange for payment by them of $300.00 each, and their services in inventing the Licensed Subject Matter.

 IV. 
 ROYALTIES 
 A. In consideration of the grant by BOARD to LICENSEE of this license, LICENSEE
shall pay to BOARD as follows: 
 1. An earned royalty of [**] of the Net Sales of a Licensed Patented Product or Process by
LICENSEE or its Subsidiaries in each country where a patent included within the BOARD Patent Rights issues, or a patent application has been filed and is pending, with claims covering such Licensed Patented Product or Process, until the expiration,
termination or invalidation of the patent in that country by a Court of final jurisdiction or the determination that a patent will not issue in that country. 
 2. An earned royalty of [**] of the Net Sales of a Licensed Non-Patented Product or Process by LICENSEE or its Subsidiaries during the
term of this Agreement. 
 3. An earned royalty of [**] of the royalty received by the LICENSEE from Net Sales of a
Licensed Patented Product or Process and Licensed Non-Patented Product or Process by sublicensees of LICENSEE or its Subsidiaries, such royalty to be measured upon and based on the actual proceeds received by LICENSEE or its Subsidiaries under the
Sublicense Agreement and not the total net sales generated by the marketing or distribution of the Licensed Patented Products or Processes and the Licensed Non-Patented Products or Processes by the sublicensee. Such earned royalty shall be due for
as long as LICENSEE or its Subsidiary is receiving proceeds from the sublicensee, but not in excess of the duration of this Agreement. 
 In
addition, in the event LICENSEE transfers or sells any of the marketing rights to any Licensed Patented Product or Process or Licensed Non-Patented Product or Process to a non-related corporation, firm, association, partnership, or other entity, the
proceeds from such sale of marketing rights is hereby expressly excluded from the terms of this Article IV, and no royalty payments shall be due thereon, provided, however, that the sales of any Licensed Patented Products or Processes or Licensed
Non-Patented Products or Processes by said entity, association, firm, partnership or corporation shall be subject to the royalty provided in this Section IV.A.3; and provided further, that the total royalty under Sections IV.A.I, IV.A.2., and
IV.A.3. shall not in any event exceed that amount which would otherwise be due and payable under Section IV.A.I. or IV.A.2., as the case may be, had such royalties been paid on the ultimate sale on such Licensed Patented Product or Process or
Licensed Non-Patented Product or Process in the marketplace. 
 4. In no event will LICENSEE be obligated to pay royalties
under Sections IV.A.1., IV.A.2. and IV.A.3. simultaneously for Net Sales of any particular product or process in any given country (except as may arise in connection with sales to a marketing entity and resales by said entity, in accordance with
Section IV.A.3. above). A single royalty will be due on each sale of Licensed Patented Products or Processes no matter how many items in the BOARD Patent Rights cover such Licensed Patented Products or Processes. No royalty shall be paid on a
Licensed Patented Product or Process after the BOARD Patent Rights covering said Licensed Patented Product or Process have expired.

 [**]
= Portions of this agreement have been omitted pursuant to a confidential treatment request. An unredacted version of this agreement has been filed separately with the Commission. 

 5. Earned royalties in the amount set out in Section IV. A. 2. shall accrue in each
country only for the period that the LICENSEE is the exclusive commercial source in that country of a Licensed Non-Patented Product or Process. The term “exclusive commercial source” as used above shall mean that the LICENSEE is the sole
commercial source of the Licensed Non-Patented Product or Process in that country and that there is no commercial product available in that country that is substantially equivalent in market acceptance. If the LICENSEE believes that it is not the
exclusive commercial source of a Licensed Non-Patented Product or Process in any designated country, then it shall so notify BOARD and provide reasonable evidence thereto. Within 45 days of receipt of said notice and evidence, BOARD shall notify the
LICENSEE in writing of its acceptance or rejection of the evidence as to the existence of another commercial source. Upon acceptance by BOARD, the LICENSEE shall, as of said date of acceptance, no longer have any obligation to pay royalties on Net
Sales in “that country based on the amount set out in Section IV.A.2. herein. In such event, the amount set out in Section IV.A.2. shall be reduced to an amount equal to [**] of the applicable amount, and LICENSEE shall pay such reduced
royalty amount. 
 6. BOARD agrees that in order to successfully market products and processes covered by this Agreement,
LICENSEE must have complete freedom in marketing. Thus, BOARD understands that LICENSEE makes no warranty that it will market the products or processes covered by this Agreement or, if LICENSEE does market any of such products or processes, that
they will be the exclusive means by which LICENSEE will participate in this field. All business decisions relating to use, manufacture, sale or marketing of products covered under this Agreement will be within the sole discretion of LICENSEE.

 7. In the event that LICENSEE enters into a joint venture with another entity and utilizes BOARD Technical Information in
combination with the technology of such entity, then Net Sales for purposes of calculating royalties shall be deemed to be LICENSEE’s income received from such joint venture. Subject to the foregoing sentence, where a Licensed Patented Product
or Process or a Licensed Non-Patented Product or Process is not sold separately but is sold in combination with or as part of other products, the Net Sales of the Licensed Patented Product or Process or the Licensed Non-Patented Product or Process
so sold shall be calculated, for the purpose of computing royalties due, by applying to the total selling price of the combination or composite product a fractional multiplier having as its denominator the total selling price of the combined or
composite product (determined by generally accepted accounting principles) and as its numerator the selling price of the included Licensed Patented Product or Process or Licensed Non-Patented Product or Process (similarly determined).

 B. Notwithstanding anything contained in Section IV.A. to the contrary, if, by May 1, 1987, BOARD
elects to exercise its rights under Section III.B. or III.C. hereof, to acquire Series A Preferred Stock and does in fact purchase or acquire any such shares of Series A Preferred Stock, the royalties provided in Section IV.A.1. and IV.A.2. will
increase in accordance with the terms set forth in Sections III.B. or III.C., as the case may be, immediately upon the closing of the applicable investment. In such event, the BOARD shall return the certificate(s) for Common Stock issued under
Article III.A. hereof to the LICENSEE, and such certificate(s) shall be thereupon cancelled and of no further effect. In the event BOARD has elected to acquire some but not all of the Series A Preferred Stock available to it, LICENSEE shall issue
BOARD a new certificate for that amount of shares of Common Stock which BOARD has not forfeited. 
 V. 
 REPORTING, PAYMENT AND MARKING 
 A. LICENSEE agrees to keep proper records and books of account in accordance with generally accepted accounting principles, showing the sales upon which the royalty payments of LICENSEE are based, and all other information necessary for the
accurate determination of payment to be made hereunder and to deliver to UTSCC, within forty-five (45) days after each calendar quarter ending on March 31, June 30, September 30 and December 31, a report showing
the information on which the payments herein provided are calculated and to accompany each such report with the payments shown to be due thereby. 
 B. On reasonable written notice, UTSCC at its own expense, shall have the right, exercisable only once in any calendar year, to have an independent certified public accountant or an appropriate representative of UTSCC, reasonably
satisfactory to LICENSEE, inspect and audit the books and records of LICENSEE, its Subsidiaries and its sublicensees during usual business hours of LICENSEE, its Subsidiaries and its sublicensees for the sole purpose of, and only to the extent
necessary for, determining the correctness of payments due under this Agreement. Such examination with respect to any fiscal year shall not take place later than three years following the expiration of such period. If such inspection and audit
results in a discrepancy in the correctness of the payments due under this Agreement in an amount in excess of five percent (5%), LICENSEE shall pay any and all costs or fees associated with said audit and charged to UTSCC by said independent
accounting firm, together with the corrected amount of royalty payments due hereunder, within thirty (30) days of receipt of the audit results. 
 C. Royalties based on Net Sales in any foreign country shall be payable to BOARD in the United States in United States Dollars. Dollar amounts shall be calculated using the foreign exchange rate, as published by the
Wall Street Journal, in effect for such foreign currency on the last business day of each calendar quarter for which a report is required. Where royalties are due for Net Sales in a country where, for reasons of currency, tax or other regulations,
transfer of foreign currency out of such country is prohibited,

 [**] = Portions of this agreement have been omitted pursuant to a confidential treatment request. An unredacted version of this agreement has been filed separately with the Commission. 

 
LICENSEE has the right to place BOARDS’s royalties in a bank account in such country in the name of and under the sole control of BOARD; provided,
however, that the bank selected be reasonably acceptable to BOARD and that LICENSEE inform BOARD of the location, account number, amount and currency of money deposited therein. After BOARD has been so notified, those monies shall be considered as
royalties duly paid to BOARD, will be completely controlled by BOARD, and LICENSEE will have no further responsibility with respect thereto. 
 D. All foreign taxes on royalty payments hereunder, imposed upon or required to be withheld by LICENSEE, its Subsidiaries or its sublicensees, shall be deducted from such payments (but not in excess of BOARD royalties), and evidence of such
foreign taxes shall be delivered to BOARD at the time of the reports with respect to such royalty payments. LICENSEE agrees, however, to assist BOARD in recovering or preventing the levy or withholding of any such taxes, provided that LICENSEE shall
be reimbursed for its out-of-pocket expenses incurred in rendering any such assistance. 
 E. LICENSEE agrees to mark all Licensed Patented
Products or Processes sold by it or its sublicensees covered by the BOARD Patent Rights with appropriate patent marking, such marking to be agreed upon between the parties hereto, together with notice of copyright sufficient to maintain legal claim
to copyright in the country of origin of such Licensed Patented Product or Process, as well as for Licensed Non-Patented Product or Process. 
 VI. 
 RESEARCH AND DEVELOPMENT 
 A. In addition to the above agreements on its part, LICENSEE has established an operating budget for the next two years equal to $600,000.00, which shall be allocated and expended in the following manner: (i) the
sum of $413,000.00 to be paid to UTSCC over the next two years for research and development of the Licensed Subject Matter and to be expended by UTSCC for salaries and fringe benefits, supplies, animals and institutional overhead; (ii) the sum
of $131,775.00 to be used by LICENSEE for direct purchases made by it for certain equipment, supplies and animals for the research and development project; and (iii) the sum of $55,000.00 to be used as working capital by LICENSEE, in its sole
discretion; all in accordance with the terms of that certain Research and Development Contract attached hereto as Exhibit D and incorporated herein for all purposes (“R & D Agreement”). In consideration thereof, BOARD and UTSCC
hereby grant to LICENSEE an exclusive, world-wide license, including the right to grant sublicenses, in and to the Base Technology, the Products, the Improvements, and all Proprietary Property (as said terms are defined in the R & D Agreement)
conceived or developed pursuant to such R & D Agreement and or work done in connection with such Agreement, to manufacture, use, market and sell any Products and Improvements (as defined therein) throughout the United States of America, its
territories and possessions, and in all foreign countries, on the same terms and conditions, with the identical rights and obligations, and governed in all respects by this License Agreement. 
  

 - 11 - 
 [**] = Portions of this agreement have been omitted pursuant to a confidential treatment request. An unredacted version of this agreement has been filed separately with the Commission. 

 B. UTSCC and its personnel shall have the right to publish papers disclosing the general scientific
findings related to the BOARD Patent Rights and BOARD Technical Information, including results of the work conducted by them on behalf of LICENSEE under the R & D Agreement, in accordance with the terms hereof and of the R & D Agreement. A
copy of each proposed publication shall be provided to LICENSEE at least ninety (90) days in advance of submission for publication thereof to permit LICENSEE time to comment thereon and to allow UTSCC and its personnel to make corrections or
revisions, where appropriate, and to permit LICENSEE or BOARD time in which to prepare application(s) for Letters Patent treating the subject matter of such publication or to take other steps necessary to protect such proprietary rights. UTSCC shall
refrain from submitting such manuscript or information for publication until the expiration of such review period. Any proposed publication provided to LICENSEE shall be considered as acceptable for the submission for publication unless LICENSEE
notifies UTSCC within said ninety (90) day period that in LICENSEE’s judgment, such publication discloses developments which are potentially patentable and may be necessary or useful to the commercial exploitation of any Products,
Improvements, the Base Technology, or Proprietary Property (as defined in said R & D Agreement). If LICENSEE notifies UTSCC in writing that such publication does disclose potentially patentable developments, UTSCC shall refrain from submitting
such manuscript or publication for the duration of the above-referenced ninety (90) day period following delivery to LICENSEE of such notice, in order for BOARD or LICENSEE to take steps to prepare and file patent applications. 
 C. Notwithstanding any other provision of this Agreement, BOARD shall specifically retain, for itself, SYSTEM, and its component institutions, the right
to use the Licensed Subject Matter, the BOARD Patent Rights, and the BOARD Technical Information for research, teaching, and other related non-commercial purposes. 
 D. UTSCC hereby agrees that it shall engage in good faith negotiations with LICENSEE on an exclusive basis, for a period of up to ninety (90) days, concerning the terms and conditions under which UTSCC and BOARD
shall agree to license, on an exclusive basis, to LICENSEE any and all New Technology (as defined in the R & D Agreement) conceived or developed by UTSCC, prior to UTSCC or BOARD discussing such New Technology with any other potential licensee
or sponsor. LICENSEE agrees, however, that any technology which is developed as a result of a research and development program sponsored by another firm as of the date hereof is excluded from this right of first refusal if such firm has rights to
acquire such technology. UTSCC agrees that it shall (1) refrain from disclosing such patentable technology to third parties or entering into negotiations or agreements with third parties with regard to the disposition of a development except as
otherwise expressly permitted by this Section VI.D.; and (2) give LICENSEE prompt 

  

 - 12 - 
 [**] = Portions of this agreement have been omitted pursuant to a confidential treatment request. An unredacted version of this agreement has been filed separately with the Commission. 

 
written notice of any such development, which notice shall specify all relevant technical and scientific information pertaining to the technology in
sufficient detail to permit LICENSEE to reasonably assess its interest in the technology and UTSCC’s projected research funding requirements, if any (the “Development Notice”). If LICENSEE delivers notice to UTSCC of its interest in a
development (“Notice of Interest”) within 90 days of delivery of the Development Notice, LICENSEE and UTSCC shall undertake negotiations for the acquisition by LICENSEE of rights to the development. If LICENSEE fails to deliver a timely
Notice of Interest, or if UTSCC, BOARD and LICENSEE fail to enter into a written agreement within 90 days of delivery of the Development Notice or such additional time as may be agreed to by the parties, BOARD and UTSCC shall be free to consult with
and license said technology to any other firm on the same terms and conditions as were last offered to LICENSEE, provided, however, that if the proposed terms of said license agreement to a third party vary from those offered to LICENSEE, BOARD and
UTSCC shall first offer the new terms to LICENSEE, which shall have 10 days to accept or reject. In the event BOARD and UTSCC do not successfully license such technology to a third party within 360 days of the expiration of the offer period to
LICENSEE, then BOARD and UTSCC shall no longer be free to offer said technology to a third party without first offering it to LICENSEE. 
 This first right of refusal by LICENSEE shall exist so long as this License Agreement between LICENSEE and the BOARD is in effect, and in no event beyond the termination of this License Agreement. LICENSEE and UTSCC agree that they will use
their respective best efforts to comply in all material respects with the terms of this section. 
 VII. 
 ADDITIONAL PATENT APPLICATIONS AND RIGHT TO FILE SUIT 
 A. 1. BOARD shall file additional patent applications in the United States and in any foreign countries in which LICENSEE notifies BOARD that LICENSEE desires applications relating to the Licensed Subject Matter to be
filed, and such additional patent applications, and all patents issuing thereon, shall be included within the BOARD Patent Rights, or, with prior approval of BOARD, LICENSEE may file any particular patent application. LICENSEE shall reimburse BOARD
for its reasonable out-of-pocket costs, plus overhead not to exceed fifty percent (50%) of BOARD’s out-of-pocket costs, including attorneys’ fees, of filing and prosecuting such additional patent applications. BOARD, at its expense,
shall be free to file in any foreign country not elected by LICENSEE, provided that BOARD provides LICENSEE with thirty (30) days advance written notice of its desire to file for any such patent. If LICENSEE does not notify BOARD within such
time period of its desire to have BOARD file for a patent on LICENSEE’s behalf, then the patent rights associated with such filing shall not be subject to this Agreement. 
  

 - 13 - 
 [**] = Portions of this agreement have been omitted pursuant to a confidential treatment request. An unredacted version of this agreement has been filed separately with the Commission. 

 2. BOARD shall have the full and complete control over the prosecution of such domestic
and foreign patent applications, but shall keep LICENSEE advised as to such patent prosecution by supplying to LICENSEE copies of any official Actions, amendments, responses and other correspondence, including copies of patents or other material
referred to or cited therein, within a reasonable period of time after receipt or filing thereof by BOARD. 
 B. 1. LICENSEE shall have the
right, exercisable at LICENSEE’s sole discretion, to file and control the prosecution of any and all suits seeking to enjoin or recover damages from any and all infringers of any patent which is then included within the BOARD Patent Rights, and
shall have the right to join BOARD as a party in any such suit filed by LICENSEE. LICENSEE shall bear the expense of any such suit, and any amounts recovered, whether by final judgment, settlement or otherwise, as a result of such suit shall be the
sole property of LICENSEE, subject to the royalty provisions of Article IV. 
 2. In the event that LICENSEE shall not
institute or prosecute any suit to enjoin or recover damages from any infringer, BOARD may do so at its sole expense, provided BOARD has first given LICENSEE 60 days’ advance notice of its intention to take such action and, provided further,
that LICENSEE has not itself taken appropriate action during such 60-day period. Any amounts recovered in an action brought by BOARD, whether by final judgment, settlement or otherwise in any such suit shall be the sole property of BOARD.

 3. LICENSEE and BOARD agree that neither will settle any action commenced by it in a manner that is prejudicial to any
BOARD Patent Rights without the other party’s prior written approval. BOARD and LICENSEE each agree that it will promptly notify the other of any infringement or potential infringement of any BOARD Patent Rights which comes to its attention.

 4. In any suit or dispute involving any infringement, BOARD and LICENSEE shall cooperate fully, and upon the request of the
party bringing suit, the other party shall make available all relevant records, papers, information, samples, specimens, and the like which may be relevant and in its possession. In the event a court of competent, final jurisdiction determines that
one or more of the BOARD Patent Rights are invalid or unenforceable, no further royalty payments on operations covered by such BOARD Patent Rights shall be due or owing hereunder with respect thereto. 
 In the event the making, using or selling of the Licensed Patented Products or Processes or Licensed Non-Patented Products or Processes is
determined, by a court of final competent jurisdiction, to infringe one or more claims of a valid, subsisting patent owned by a third party, no royalty payments shall be due BOARD with respect to such product or process from such infringing
activities in that jurisdiction from the time such determination is made until such patent expires. In the event that 

  

 - 14 - 
 [**] = Portions of this agreement have been omitted pursuant to a confidential treatment request. An unredacted version of this agreement has been filed separately with the Commission. 

 
either party is able to negotiate a license with royalties based on a good faith assessment of the strength and enforceability of said third party’s
patent, royalty payments due hereunder will be paid only to the extent that such payments exceed any royalty payments made by LICENSEE to such third party as a result of such negotiated license but in no event shall such payments be reduced below
fifty percent (50%) of that otherwise due. 
 VIII. 
 DURATION AND TERMINATION 
 A. Unless otherwise provided herein, this Agreement shall remain in
force and effect until the expiration of the last patent relating to the Licensed Subject Matter and, at the option of LICENSEE, from year to year thereafter; however, it is understood that no royalties shall be due on any sales of Licensed Patented
Products or Processes and Licensed Non-Patented Product or Processes in any country where the applicable BOARD Patent Rights have previously expired or where, pursuant to other provisions of this Agreement, no further royalty payments are due for
other reasons. 
 B. This Agreement may be terminated by either party, if the other party substantially fails to perform or otherwise
materially breaches any of the material terms, covenants or provisions of this Agreement, such termination to be effected in accordance with the provisions hereof. In such event, the non-breaching party shall give written notice of intent to
terminate to the breaching party stating the grounds therefor. The party receiving the notice shall have sixty (60) days thereafter to correct such breach. If such breach is not corrected within said sixty (60) days after notice as
aforesaid, then the party sending the notice of intent to terminate, at its option, may terminate this Agreement by further written notice thereof to the party in breach, provided however, that if such breaching party notifies the terminating party
that it is in good faith attempting to cure such breach, describing the manner thereof, or if the breach is incurable and the breaching party is willing to compensate in damages, such termination may not occur during the period of such cure or
negotiation of damages. 
 C. After three (3) years from the effective date of this Agreement, BOARD shall have the right, upon ninety
(90) days’ written notice, to terminate this Agreement if LICENSEE has failed to commercialize the Licensed Subject Matter. If, as of said date, LICENSEE has commercialized some but not all aspects of the Licensed Subject Matter, then the
BOARD’s right to terminate this Agreement shall not apply. Furthermore, if the LICENSEE shall demonstrate to the reasonable satisfaction of the BOARD that it has an ongoing and active research, developmental, manufacturing, marketing, clinical
testing, or licensing program, directed toward production and sale of products, then LICENSEE shall be deemed to have satisfied the requirements herein to commercialize the Licensed Subject Matter.

 D. In the event of termination of the Agreement in whole or in part for any reason whatsoever, the
following shall apply, limited, however, to those BOARD Patent Rights being terminated and applicable Licensed Patented Products or Processes and Licensed Non-Patented Products or Processes: 
 1. LICENSEE shall not thereby be discharged from any liability or obligation to BOARD which became due or payable prior to the effective
date of such termination; 
 2. If LICENSEE, its Subsidiaries or its sublicensees then possess Licensed Patented Products or
Processes or Licensed Non-Patented Products or Processes, have started the manufacture thereof or have accepted orders therefor, LICENSEE, its Subsidiaries or sublicensees shall have the right to sell their inventories thereof, complete the
manufacture thereof and market such fully manufactured Licensed Patented Products or Processes or Licensed Non-Patented Products or Processes, and/or manufacture and sell Licensed Patented Products or Processes or Licensed Non-Patented Products or
Processes, in order to fulfill such accepted orders, subject to the obligation of LICENSEE to pay BOARD the earned royalty payments therefor as provided in Section IV of this Agreement; 
 3. Subject to Section VIII.D.2., LICENSEE shall discontinue, and shall cause its Subsidiaries and sublicensees to discontinue, the
manufacture, use, marketing and sale of Licensed Patented Products or Processes or Licensed Non-Patented Products or Processes, and shall assign any sublicenses granted hereunder to BOARD, and LICENSEE shall immediately discontinue use of the words
“Board of Regents, The University of Texas System”, “University of Texas System Cancer Center”, or any language which would connect sales of products by LICENSEE with or imply the sponsorship of BOARD, except that packaging and
advertising material may be used for products permitted to be sold under Section VIII.D.2. above; and 
 4. All rights sold,
assigned or transferred by BOARD to LICENSEE hereunder and then subject to termination shall revert to BOARD, and LICENSEE agrees to execute all instruments necessary and desirable to revest said rights in BOARD.

 Exhibit A 
 to 
 Exclusive License Agreement 
 To induce the LICENSEE to deliver the above-specified Common Stock to the BOARD, BOARD hereby represents and warrants to the LICENSEE as follows:

 1. BOARD is acquiring the Common Stock for its own account as principal, for investment purposes only, and not with a view to, or for,
resale or distribution, and no other person has a direct or indirect beneficial interest in the Common Stock; 
 2. The BOARD has not offered
any of the Common Stock for resale and has no present intention of dividing its interest with others or of reselling or otherwise disposing of the Common Stock; 
 3. The BOARD further represents, warrants and agrees that it will not sell or otherwise dispose of the Common Stock without registration under the Securities Act of 1933, as amended (the “Act”), or an
exemption therefrom, and fully understands and agrees that it must bear the economic risk of its investment for an indefinite period of time because, among other reasons, the Common Stock has not been registered under the Act or under the securities
laws of any state and, therefore, cannot be resold, pledged, assigned or otherwise disposed of unless they are subsequently registered under the Act and under the applicable securities laws of such states or an exemption from such registration is
available. BOARD also understands that the LICENSEE is under no obligation to register the Common Stock on its behalf or to assist it in complying with any exemption from registration under the Act. BOARD further understands that any certificate
evidencing the Common Stock will bear a legend restricting the transfer thereof consistent with the foregoing and that a notation may be made in the records of the LICENSEE restricting the transfer of any Common Stock in a manner consistent with the
foregoing.
