Rights and the BOARD Technical Information to manufacture, use, market and sell any Licensed Patented Product or Process and any Licensed Non-Patented Product or Process throughout the United States of America, its territories and possessions and in
all foreign countries. 
 B. BOARD and UTSCC hereby grant to LICENSEE the 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 LICENSEE shall not be obligated to use the name “Board of
Regents, The University of Texas System” or “The University of Texas System Cancer Center” in any manner. 
 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, federal, foreign or local regulatory authority which relate in any manner to the BOARD Patent Rights or the
BOARD Technical Information, and BOARD and UTSCC agree that they will not use, or permit the use of, such information and 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, 

  

 - 3 - 

 
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 any Licensed
Patented Product or Process or Licensed Non-Patented Product or Process for use in any application thereof. BOARD and UTSCC shall execute any and all documents reasonably necessary to obtain such approvals upon request by LICENSEE. LICENSEE shall
reimburse BOARD and UTSCC for any reasonable out-of-pocket costs, plus overhead not to exceed 50% of out-of-pocket costs, including attorneys’ fees, incurred by BOARD and UTSCC in connection with such cooperation. At such time as clinical
trials are commenced, LICENSEE agrees that it will enter into an appropriate agreement with UTSCC regarding the conduct of such trials. 
 D.
UTSCC shall promptly provide LICENSEE and shall continue to provide LICENSEE, during the term of this Agreement, with all information relating to (i) pharmacological, toxicological or clinical data, (ii) synthetic, formulative,
manufacturing or analytical data, and (iii) such other chemical, physical or biological data which UTSCC may now or in the future possess or control which relates in any manner to the Licensed Subject Matter, except for that information made

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: 
 1. BOARD, through UTSCC, is consulted beforehand and is reasonably satisfied that the third party does in fact hold a patent that limits
LICENSEE’s competitiveness in making or marketing Licensed Patented Products or Processes or Licensed Non-Patented Products or Processes; 
 2. In BOARD’s reasonable judgment, the rights received by LICENSEE under such cross-licensing agreement cover only Licensed Patented Products or Processes or Licensed Non-Patented Products or Processes and are
not directed to other products; 
 3. BOARD incurs no financial or legal liabilities under the cross-licensing; 
 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. 
 ISSUANCE OF COMMON STOCK AND PREFERRED STOCK 
 A. In consideration of the right to use the
names set forth in Section 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 shall be subject to cancellation in accordance with the terms of Sections III.B. and III.C. below. In addition, LICENSEE agrees to reserve a seat on its Board of Directors for a designee selected by BOARD, until the
closing of the first public offering of equity securities by LICENSEE. In accordance with LICENSEE’S customary practice with respect to offerings of any securities of the LICENSEE, BOARD hereby makes the representations, warranties and
covenants to LICENSEE contained in Exhibit A hereto, which Exhibit A is incorporated herein for all intents and purposes. 
 B. In addition,
LICENSEE hereby grants BOARD an option, exercisable in its sole discretion, to elect to purchase a total of 600,000 shares of the Series A Preferred Stock (the “Shares”) of LICENSEE, at a purchase price of $.50 per share, on the same
general terms and conditions as are applicable to the initial purchasers of such Series A Preferred Stock, such purchase option to be subject to and conditioned upon the following: 
 1. The BOARD shall have the option to purchase all of the Shares, or a lesser amount in accordance with the schedule attached hereto as
Exhibit B and incorporated herein for all purposes, by providing written notice to LICENSEE to such effect no later than May 1, 1987, which notice shall specify the number of Shares which BOARD desires to purchase and the date of purchase,
which date shall not be later than May 30, 1987. Effective at 12:01 a.m., May 2, 1987, the option hereinabove provided shall expire for any and all Shares as to which the LICENSEE has not received such written notice, and BOARD shall have
no further right to purchase any such Shares, unless otherwise extended by agreement of the parties. 
 2. In the event that
BOARD does properly elect to exercise its right to purchase any of the 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. 
  

 - 5 - 

 3. Effective upon the purchase by BOARD of any or all of the Shares, the royalty
obligations of LICENSEE provided for in Section IV.A.1. and IV.A.2. shall increase to the applicable percentage amount as provided in the Schedule attached hereto as Exhibit B. 
 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
Preferred Stock of LICENSEE, such election option to be exercised in accordance with and subject to the following conditions: 
 1. BOARD shall have the right to contribute funds, in accordance with the schedule set out on Exhibit B hereto, for research and development activities of LICENSEE, by providing written notice to LICENSEE no later than May 1, 1987,
which notice shall specify the amount of funds which BOARD desires to contribute and the date of such contribution, which date shall not be later than May 30, 1987. Effective at 12:01 a.m. on May 2, 1987, BOARD’S option to acquire
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. 
  

 - 6 - 

 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: 
 1. 8% Convertible Notes (the “Notes”), in the amount of
$300,000, such Notes to accrue interest at the rate of 8% per year until the Notes are converted to Series A Preferred Stock or redeemed by 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 three
percent (3%) 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.

  

 - 7 - 

 2. An earned royalty of two percent (2%) 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 forty percent
(40%) 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. 
 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 

  

 - 8 - 

 
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
one-third (1/3) 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, 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. 
  

 - 10 - 

 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. 
 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 

  

 - 11 - 

 
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 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, 

  

 - 12 - 

 
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. 
 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 

  

 - 13 - 

 
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 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. 
  

 - 14 - 

 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; 
  

 - 15 - 

 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. 
 C. The BOARD acknowledges that it is aware that: 
 (1) No federal or state agency has passed upon the Common Stock or made any finding or determination as to fairness of this investment;

 (2) There are substantial risks of loss of investment incident to an investment in the Common Stock and such an investment
is highly speculative; 
 (3) The LICENSEE is only recently organized, has not conducted any substantial business to date and
does not have any substantial working capital or financial resources. The business in which the LICENSEE proposes to engage is highly speculative and success in the LICENSEE’s business may depend on, among other things, the LICENSEE’S
ability to obtain financing, to complete product development, to

 II. 
 GRANT OF RIGHTS 
 A. BOARD hereby grants to LICENSEE and its Subsidiaries, for the term of
this Agreement (subject to the provisions of Paragraph VI.C. herein), an exclusive, world-wide license, including the right to grant sublicenses, under (1) the BOARD Patent Rights, (2) the BOARD Technical Information, excluding from
(1) and (2) those Improvements first conceived after the termination of the R & D Contract, and (3) Related Technology, to manufacture, use, market and sell any Product throughout the United States of America, its territories and
possessions and in all foreign countries. 
 B. UTSCC and BOARD hereby grant to LICENSEE a right of first refusal to an exclusive,
world-wide, royalty bearing license for Improvements first conceived after the termination of the R & D Contract but before the termination of this Agreement, provided that the rights to such Improvements are not already owned by a third party.
UTSCC and BOARD agree that they shall (1) refrain from disclosing such Improvements to third parties (except as provided in Article V herein) or entering into negotiations or agreements with third parties with regard to the disposition of an
Improvement except as otherwise expressly permitted by this Agreement; and (2) give LICENSEE prompt written notice of any such Improvement, which notice shall specify all relevant technical and scientific information pertaining to the
Improvement in sufficient detail to permit LICENSEE to reasonably assess its interest in the Improvement and UTSCC’s projected research funding requirements, if any (the “Improvement Notice”). If LICENSEE delivers notice to UTSCC of
its interest in an Improvement (“Notice of Interest”) within 15 days after delivery of the Improvement Notice, LICENSEE and UTSCC shall undertake negotiations for the acquisition by LICENSEE of rights to such Improvement. If LICENSEE fails
to deliver a timely Notice of Interest, or if UTSCC, Board and LICENSEE fail to enter into a written agreement within 60 days after delivery of the Notice of Interest or such additional time as may be agreed to by the parties, Board and UTSCC shall
be free to consult with and license such Improvement to any other firm and LICENSEE shall have no further rights to the Improvement. BOARD and UTSCC shall not enter into any agreement with any other party unless such agreement is, overall, more
favorable to UTSCC than the last offered by LICENSEE. 
 C. BOARD and UTSCC hereby grant to LICENSEE the right to use the names “Board
of Regents, The University of Texas System”, “M. D. Anderson Hospital and Tumor Institute” and “The University of Texas System Cancer Center” (“Names”) to the extent necessary to enforce and protect LICENSEE’S
rights under Board Patent Rights; and subject to the written approval of UTSCC and, where required, BOARD, to use the Names for such other purposes as UTSCC and BOARD shall permit and may, under law, allow ; provided however, that LICENSEE shall not
be obligated to use such Names in any manner. 
  

 4 

 D. 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, federal, foreign or local regulatory authority which relate in any manner to the BOARD Patent Rights or the BOARD Technical Information, and BOARD and UTSCC agree that they will not use, or permit the use of,
such information and 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 Product. 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 any Product for use in any application thereof. BOARD and UTSCC shall execute any and all documents reasonably necessary to obtain such approvals
upon request by LICENSEE. LICENSEE shall reimburse BOARD and UTSCC for any reasonable out-of-pocket costs, plus overhead not to exceed 50% of out-of-pocket costs, including attorneys’ fees, incurred by BOARD and UTSCC in connection with such
cooperation. At such time as clinical trials are commenced, LICENSEE agrees that it will enter into an appropriate agreement with UTSCC regarding the conduct of such trials but LICENSEE shall not be required to conduct such trials at UTSCC.

 E. UTSCC shall promptly provide LICENSEE and shall continue to provide LICENSEE, during the term of this Agreement, with all information
relating to (i) pharmacological, toxicological or clinical data, (ii) synthetic, formulative, manufacturing or analytical data, and (iii) such other chemical, physical or biological data which UTSCC may now or in the future possess or
control which relates in any manner to the Licensed Subject Matter or Improvements, except for that information made confidential by law or prior agreement. 
 F. The parties recognize that LICENSEE may encounter patents or other proprietary rights held by third parties which dominate activities covered by the BOARD Patent Rights or BOARD Technical Information, and that
cross-licenses between the BOARD (or LICENSEE) and such third parties may be necessary in order to enable LICENSEE to exercise the rights granted under this Agreement. 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 or BOARD Technical Information, provided: 
 1. BOARD and UTSCC are consulted beforehand and are reasonably satisfied that the third party does in fact hold a patent or own other proprietary rights that limits LICENSEE’s ability to exercise the rights granted herein. 

 

 5 

 2. In BOARD’s and UTSCC’s reasonable judgement, the rights received by LICENSEE
under such cross-licensing agreement cover only Licensed Patented Products or Processes or Licensed Non-Patented Products or Processes and are not directed to other products; 
 3. BOARD incurs no financial or legal liabilities under the cross-licensing; 
 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 Paragraph III.A.3.), received by LICENSEE in exchange for such cross-licensing is treated as Net Sales for Products. 
  

 6 

 III. 
 ROYALTIES AND PAYMENTS 
 A. In consideration of the grant by BOARD to LICENSEE of this
license, LICENSEE shall pay to UTSCC as follows: 
 1. For each Licensed Patented Product or Process, an earned royalty as set
forth in the schedule below: 
  

				
	 Royalty Basis
	  	Royalty Rate	 
	 $0 - $10 million
	  	10	%
	 $10 million - 35 million
	  	5	%
	 Over $35 million
	  	3	%

 of the Net Sales made by LICENSEE or its Subsidiaries in all countries where a patent included
within the BOARD Patent Rights issues, or a patent application included within the BOARD Patent Rights has been filed and is pending, with claims covering such Licensed Patented Product or Process, until the expiration or other termination of such
patents or applications, or a determination of the invalidity or unenforceability thereof by a court of final jurisdiction or the determination that such patent will not issue. 
 For purposes of calculating royalties under the above schedule (under this Paragraph III.A.1. and the following Paragraph III.A.2.), and
for reporting purposes hereunder, each separate therapeutic drug, regardless of application, shall be considered a single licensed Product or Process, and all non-therapeutic Products and Processes shall be considered in the aggregate as a single
licensed Product or Process. 
 2. An earned royalty of one-half the rate described in Paragraph III.A.1., hereinabove, for
the same schedule of Net Sales for each Licensed Non-Patented Product or Process by LICENSEE or its Subsidiaries during the term of this Agreement. Further, and except as provided in Paragraph III.A.4., if a Licensed Patented Product or Process
becomes a Licensed Non-Patented Product or Process (e.g. upon abandonment of a previously pending patent application), the royalty basis shall include Net Sales of said Product or Process made when said Product or Process was a Licensed Patented
Product or Process. 
 3. An earned royalty of forty percent (40%) of the royalty received by the LICENSEE or its
Subsidiaries from their sublicensees hereunder, 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 Products by the sublicensee. Such earned royalty shall be due for as long as LICENSEE or its Subsidiary is receiving from the sublicensee proceeds relating to the rights licensed hereunder, 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 Product to a
non-related corporation, firm, association, partnership, or other entity, the proceeds from such sale of marketing rights is hereby expressly 

  

 7 

 
excluded from the terms of this Article III, and no royalty payments shall be due thereon, provided, however, that income to LICENSEE derived from the sales
of any Product by said entity, association, firm, partnership or corporation shall be subject to the royalty provided in this Paragraph III.A.3; and provided further, that the total royalty under Paragraphs III.A.1., III. A.2. and III.A.3. shall not
in any event exceed that amount which would otherwise be due and payable under Paragraphs III.A.1. or III.A.2., as the case may be, had such royalties been paid on the ultimate sale of such Product in the marketplace. 
 4. In no event will LICENSEE be obligated to pay royalties under Paragraphs III.A.1., III.A.2. or III.A.3 simultaneously for Net Sales of
any particular Product in any given country. A single royalty will be due on the sale of each Product by LICENSEE or its Subsidiaries, no matter how many items in the BOARD Patent Rights or BOARD Technical Information cover such Product. No royalty
shall be due or payable on a Licensed Patented Product or Process after the BOARD Patent Rights covering said Licensed Patented Product or Process have expired. 
 5. Earned royalties in the amount set out in Paragraph III.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, except as may otherwise be provided, brought about, or allowed by LICENSEE. 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 also 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 Paragraph III.A.2. herein. In such event, the amount set out in Paragraph III.A.2. shall be reduced to an amount equal to one-third (1/3) of the applicable
amount, and LICENSEE shall pay such reduced royalty amount. 
 6. Except as provided in Paragraph VI. C., below, BOARD
understands that, in order to successfully market Products and Processes covered by this Agreement, 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. 
  

 8 

 7. In the event that LICENSEE enters into a joint venture with another entity and
utilizes the rights granted herein in combination with the technology of such entity or any of LICENSEE’s technology not subject to this Agreement, then Net Sales for purposes of calculating royalties as provided in Paragraphs III.A.1 or
III.A.2. hereunder, as the case may be, shall be deemed to be LICENSEE’s income received from such joint venture that is derived from utilization of the rights granted herein. 
 8. Where a Product is not sold separately but is sold in combination with or as part of other products, the Net Sales of the Product 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 Product (similarly determined). 
 9. LICENSEE shall pay UTSCC cash bonuses of $200,000.00 for each NDA approved Product conceived, discovered, or reduced to practice by the
Researchers/Inventors. 
  

 9 

 IV. 
 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%) of the monies due to UTSCC for any single quarter audited, 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, or give notice of challenge or intent to challenge the audit results, within thirty (30) days after LICENSEE’s receipt of the audit results. Upon determination that such
a challenge has failed, LICENSEE shall make any required payments, as described in the preceding sentence, together with interest thereon at the per annum prime rate announced or established by Texas Commerce Bank, National Association, Houston,
Texas during the period of nonpayment or at the maximum rate allowed by law, whichever is lower. 
 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 (corrected for typographical errors), 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, LICENSEE has the right to place UTSCC’s royalties in a bank account in such country in the name of and under the sole control of UTSCC; provided, however, that the bank selected be reasonably acceptable to UTSCC and
that LICENSEE inform UTSCC of the location, account number, amount and currency of money deposited therein. After UTSCC has been so notified, those monies shall be considered royalties duly paid to UTSCC, will be completely controlled by UTSCC, and
LICENSEE will have no further responsibility with respect thereto. 
  

 10 

 D. All foreign taxes on royalty payments hereunder, imposed upon or required to be withheld from such
royalty payments by LICENSEE, its Subsidiaries or its sublicensees, shall be deducted from such payments (but not in excess of BOARD royalties). LICENSEE shall make timely payment of such foreign taxes and evidence of such timely payment 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, and where there is a copyright interest to be protected, to provide notice of copyright for
the Product sufficient to maintain legal claim to copyright in the country of origin of such Product. 
  

 11 

 V. 
 ADDITIONAL PATENT APPLICATIONS AND RIGHT TO FILE SUIT 
 A. 1. LICENSEE shall reimburse BOARD
for its reasonable out-of-pocket costs, including attorneys’ fees, of filing and prosecuting the existing patents or patent applications included in Schedule I attached hereto. 
 2. 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 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, 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 and that no filing deadline would be missed by such notice. 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 licensed under this Agreement. 
 3. 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. 
 4. In the event that BOARD elects not to file or prosecute a
patent application relating to the Licensed Subject Matter, LICENSEE shall have the right to file and prosecute any such application at its own expense and such application shall be included in BOARD Patent Rights and subject to the terms of this
Agreement. 
 B. 1. LICENSEE shall have the right, exercisable at LICENSEE’s sole discretion, to file and control the prosection 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 or any proprietary Rights within the BOARD Technical Information, 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 judgement, settlement or otherwise, as a result of such suit shall be the sole property of LICENSEE,
the net proceeds of which (after deductions for attorney’s fees and other reasonable expenses incurred in conjunction with such proceedings) shall be subject to the royalty and reporting provisions of Articles III and IV, and treated as
additional Net Sales of a single Product. 
  

 12 

 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 or advised
BOARD of its intent to take appropriate action during such 60-day period. Any amounts recovered in an action brought by BOARD, whether by final judgement, 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
or BOARD Technical Information 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 or BOARD Technical
Information 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 appropriate personnel and all relevant records, papers, information, samples, specimens, and the like which may be relevant and in its
possession or control. In the event a court of final jurisdiction determines that the BOARD Patent Rights (or any portion thereof) are invalid or unenforceable, no further royalty payment on the Product arising from the invalid or unenforceable
Board Patent Rights or such portion thereof (as applicable), shall be due or owing hereunder. 
 5. Except as otherwise
provided in this Paragraph V.B.5 or Paragraph II.F., 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 or other proprietary right 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 or other proprietary right expires. In the event that any party hereto is able to negotiate with a third party a license for royalties based on a good faith assessment of the strength and
enforceability of said third party’s patent or other proprietary right, royalty payments due under Article III 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. 
  

 13 

 VI. 
 DURATION AND TERMINATION 
 A. Unless otherwise provided herein, this Agreement shall remain in
full force and effect until the later to occur of (i) the expiration of the last patent relating to the Licensed Subject Matter or Improvement licensed hereunder or (ii) seventeen (17) years from the date of the last Notice of
Acceptance (as hereinafter defined). A “Notice of Acceptance” is a written communication by one of UTSCC and LICENSEE to the other of such parties advising (a) in the case of such notice originating from UTSCC, that new technology
covered by this Agreement has been licensed to LICENSEE hereunder, or (b) in the case of such notice originating from LICENSEE, that LICENSEE has accepted the license of new technology that is covered by this Agreement; or, in the event that no
patent issues and no such Notice of Acceptance is given under rights granted herein, this Agreement automatically terminates seventeen (17) years after the effective date of this Agreement. It is understood that no royalties shall be due on any
sales of Licensed Patented Products 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. BOARD shall have the right, upon ninety (90) days’ written notice, to terminate the license grant with respect to a
particular Product without terminating this Agreement if LICENSEE has failed to commercialize such Product. 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 such Product, then LICENSEE shall be deemed to have satisfied the requirements herein to commercialize such Product. 
  

 14 

 D. In the event either LICENSEE or UTSCC (a) discontinues business, except for assignments permitted
pursuant to Article X herein, or pursuant to the granting of any sublicenses permitted hereunder to the extent that such sublicenses do not conflict with Article X herein, (b) applies for or consents to appointment of a receiver, trustee or
liquidator for it or all or a substantial portion of its assets, (c) has filed against it an involuntary petition in bankruptcy which is not dismissed or stayed within one hundred twenty (120) days of filing, or (d) files a voluntary
petition in bankruptcy or a petition or answer seeking reorganization or an arrangement with creditors or seeking to take advantage of any other law (whether federal or state) relating to relief of debtors, then at any time thereafter for so long as
such event continues in effect, UTSCC, with respect to any such action by or against LICENSEE, and LICENSEE, with respect to any such action by or against UTSCC, may terminate this Agreement with respect to such defaulting party upon written notice
thereof to the defaulting party, provided, however, that with respect to the occurrences described in (b), (c) and (d) above, this Agreement shall not be terminable so long as LICENSEE is in good faith attempting to reorganize, pursuant to
Chapter 11 of the Bankruptcy Code, so as to continue its operations. 
 E. 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 and BOARD Technical Information being terminated and applicable Products: 
 1. No party shall thereby be discharged from any liability or obligation to any other party which became due or payable prior to the
effective date of such termination; 
 2. If LICENSEE, its Subsidiaries or its sublicensees then possess Products, 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 Products, and/or
manufacture and sell Products, in order to fulfill such accepted orders, subject to the obligation of LICENSEE to pay BOARD the earned royalty payments and provide the reports therefor as provided in Articles III and IV of this Agreement;

 3. Subject to Paragraph VI.E.2., LICENSEE shall discontinue, and shall cause its Subsidiaries and sublicensees to
discontinue, the manufacture, use, marketing and sale of Products, and shall, at BOARD’S option, terminate or assign any sublicenses granted hereunder to BOARD, and LICENSEE shall immediately discontinue use of the Names; 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. 
 5. LICENSEE’S right
to file and prosecute suits against infringers for activities occurring during the term of this Agreement shall survive the termination or expiration of this Agreement.

 Each party’s obligation of confidence
hereunder shall be fulfilled by using the same degree of care with the other party’s confidential information it uses to protect its own confidential information. Nothing contained herein shall prevent BOARD, UTSCC or LICENSEE, its Subsidiaries
or its sublicensees from disclosing information to the extent such information is required to be disclosed, and after securing or making a good faith effort to secure confidentiality limitations comparable to the foregoing, (i) in connection
with the securing of necessary governmental authorization for LICENSEE’s, its Subsidiaries’ or sublicensees’ manufacture, use or sale of a Licensed Patented Product or Process or Licensed Non-Patented Product or Process, (ii) for
the purpose of BOARD’s, UTSCC’s, LICENSEES’s, or any of their Subsidiaries’ or sublicensees’ compliance with governmental regulations, (iii) for the purpose of sublicensing or distribution and sale as provided for
herein, or (iv) in connection with the development, manufacture, use or sale of any Product as provided for herein. 
 Except as herein
expressly provided, or as provided in the R & D Contract, UTSCC and BOARD further agree that they will not use the BOARD Patent Rights or BOARD Technical Information for the benefit of any party other than LICENSEE, itself and Board, or that any
such use (except as provided for noncommercial academic purposes) shall be solely for the performance of its obligations under such Agreement. UTSCC shall obtain appropriate written agreements from all persons other than employees that may have
access to the BOARD Patent Rights or BOARD Technical Information pursuant to which such party agrees to so maintain in strict confidence all such material and not to use such material except for the benefit of LICENSEE, UTSCC or Board, and UTSCC
shall obligate all employees to maintain the confidentiality of all such information and not to use such material except as permitted in such 

  

 17 

 
Agreements. The obligations imposed by this section shall exist for so long as this Agreement is in force and for a period of three (3) years
thereafter, unless a license grant is terminated for failure to commercialize in accordance with Paragraph VI. C., above, or for failure to pay as provided in Articles III and IV, or because of any other material default of LICENSEE hereunder, in
which cases UTSCC’s and BOARD’s obligations of confidentiality with respect to such Licensed Subject Matter also terminate. 
  

 18

 XII.

 INDEMNIFICATION 
 A. LICENSEE agrees to indemnify and hold harmless UTSCC, SYSTEM, BOARD and their Regents, officers, agents and employees (“Indemnified Person”) from any liability, loss or damage they may suffer as a result of claims, demands,
costs or judgments against them arising out of the activities conducted pursuant to this Agreement, provided, however, that any such liability, loss or damage resulting from, arising out of, or incident to, directly or indirectly, the following
subsections a. or b. is excluded from this indemnification: 
 a. Any negligent or willful failure to comply with any
applicable FDA or other governmental requirements; or 
 b. The negligence or willful malfeasance of an Indemnified Person.

 UTSCC agrees to endeavor in good faith to provide LICENSEE with a copy of a notice of claim or action which is a matter subject to indemnification in
accordance with the terms hereof, in order for LICENSEE to defend such claim or action. LICENSEE shall have the right to control the defense of any such claim or action, at its own expense. UTSCC and Board agree to cooperate with LICENSEE in the
defense of such claim or action. Failure of UTSCC to notify LICENSEE as required above or to cooperate with 

  

 20 

 
LICENSEE, which failure materially adversely affects LICENSEE’s ability to defend such claim or action or directly results in LICENSEE incurring
liability hereunder, shall relieve LICENSEE from any obligation of indemnification hereunder. In the event that an Indemnified Person who is no longer associated with UTSCC, SYSTEM or BOARD fails to notify UTSCC, BOARD or LICENSEE of, or cooperate
with LICENSEE with respect to, any claim or action which is a matter subject to indemnification in accordance with the terms hereof, which failure materially adversely affects LICENSEE’s ability to defend such claim or action or directly
results in LICENSEE incurring liability hereunder, LICENSEE shall be relieved from its obligation of indemnification to such Indemnified Person hereunder. 
 XIII.

 BOARD, UTSCC, and LICENSEE acknowledge that any party hereto may wish to distribute periodically informational releases and announcements to the news
media regarding this Agreement. No party shall release such materials containing the name of another party or any of its employees without the prior approval by an authorized representative of such party, which said approval shall not be
unreasonably withheld. Should a party reject a proposed news release, the parties agree to discuss the reasons for such rejection, and every effort shall be made to develop an appropriate informational news release.
