ensure that no Affiliate of the Issuer shall, sell, offer for sale or solicit offers to buy or otherwise negotiate in respect of any security (as defined in Section 2 of the Securities Act) that will be integrated with the offer or sale of the
Issuer Shares pursuant to this Agreement in a manner that would require the registration under the Securities Act of the sale of the Issuer Shares to MD Anderson, or that will be integrated with the offer or sale of the Issuer Shares pursuant to

6.7 Construction. The headings herein are for convenience only, do not constitute a part of this Agreement and shall not be deemed to

pertain to MD Anderson are enforceable only to the extent authorized by the Constitution and laws of the State of Texas 

  
 15. 

 6.11 Governing Law; Dispute Resolution. This Agreement will be governed by the laws of the
State of Texas without regard to conflict of law principles. In the event of any dispute between the Issuer on the one hand, and MD Anderson on the other (a “Dispute”), the parties agree that such Dispute shall be first submitted
for resolution for a period of ten (10) calendar days to designated senior officers of each of the parties who hold legal authority to resolve and settle such dispute. If any Dispute cannot be resolved and settled within such period, then to
the extent authorized by the law governing the power and authority of each party, the parties agree to submit such Dispute to full and binding arbitration that will be undertaken and conducted under the auspices of the American Arbitration
Association by a panel of three (3) arbitrators pursuant to that organization’s Commercial Arbitration Rules then in effect, as modified by and subject to the following terms: 

(a) MD Anderson, on the one hand, and the Issuer, on the other, will each choose one arbitrator and those two arbitrators will select the
third arbitrator. 
 (b) The fees and expenses of the arbitrators shall be borne in equal shares by the parties. 

(c) Each party shall bear the fees and expenses of its legal representation in the arbitration. 

(d) The arbitral tribunal shall not reallocate either the fees and expenses of the arbitrators or of the parties’ legal representation.

 (e) The arbitration shall be held in Nashville, Tennessee, USA which shall be the seat of the arbitration. 

(f) The arbitrators may not award, and no party may seek, indirect, incidental, consequential, punitive, exemplary, special, or enhanced
damages, or prejudgment interest, or attorneys’ fees or costs, nor may the arbitrators apply any multiplier to any award of actual damages, except as may be required by statute. 

(g) The arbitrators must issue a reasoned award, setting forth the arbitrators’ findings of fact and conclusions of law. 

(h) The award of the arbitrators may be entered in any court of competent jurisdiction. The award rendered by the arbitrators shall be final
and binding on the parties, except that the award is subject to limited judicial review and vacatur for the following reasons only: (i) the award was procured by corruption, fraud, or undue means, (ii) the award was tainted by evidence of
partiality or corruption by any of the arbitrators, (iii) the award was tainted by misconduct by any of the arbitrators, (iv) the arbitrators exceeded their powers, and/or (v) the award evidences a manifest disregard of the law or is
contrary to public policy. If the parties are unable to resolve a Dispute through binding arbitration, then any lawsuit pertaining to such Dispute that is brought by one party against another must be presented to and decided by a state or federal
court in the home locale of the defendant party (that being Houston, Texas for MD Anderson and Germantown, Maryland for the Issuer). 

  
 16. 

 6.12 Counterparts; Execution. This Agreement may be executed in three (3) or more
counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument. Counterparts may be delivered via facsimile, electronic mail (including pdf or any electronic signature complying with
the U.S. federal ESIGN Act of 2000, e.g., www.docusign.com) or other transmission method and any counterpart so delivered shall be deemed to have been duly and validly delivered and be valid and effective for all purposes. 

6.13 Severability. If any provision hereof should be held invalid, illegal or unenforceable in any respect, then, to the fullest extent
permitted by law, (a) all other provisions hereof shall remain in full force and effect and shall be liberally construed in order to carry out the intentions of the parties as nearly as may be possible and (b) the parties shall use their best
efforts to replace the invalid, illegal or unenforceable provision(s) with valid, legal and enforceable provision(s) which, insofar as practical, implement the purposes of such provision(s) in this Agreement.

otherwise; provided, that this Section 4.1 shall not apply to any transfer of Issuer Shares by MD Anderson to its Affiliates, provided that as a condition of such transfer, such Affiliate agrees in writing to be bound by the provisions of this

 6.7 Construction. The headings herein are for convenience only, do not constitute a part
of this Agreement and shall not be deemed to limit or affect any of the provisions hereof. The language used in this Agreement will be deemed to be the language chosen by the parties to express their mutual intent, and no rules of strict
construction will be applied against any party.

condition of such transfer, such transferee agrees in writing to be bound by all of the terms and conditions of this Agreement as a party hereto and (iii) such transfer shall have been made in accordance with the applicable requirements of this

 6.9 Persons Entitled to Benefit of Agreement. This Agreement is intended for the
benefit of the parties hereto and their respective permitted successors and assigns and is not for the benefit of, nor may any provision hereof be enforced by, any other person. 

6.10 State Agency Limitations. MD Anderson is an agency of the State of Texas and under the Constitution and laws of the State of Texas
possesses certain rights and privileges, is subject to certain limitations and restrictions, and only has such authority as is granted to it under the Constitution and laws of the State of Texas. Notwithstanding any provision hereof, nothing in this
Agreement is intended to be, nor will it be construed to be, a waiver of the sovereign immunity of the State of Texas or a prospective waiver or restriction of any of the rights, remedies, claims, and privileges of the State of Texas. Moreover,
notwithstanding the generality or specificity of any provision hereof, the provisions of this agreement as they pertain to MD Anderson are enforceable only to the extent authorized by the Constitution and laws of the State of Texas. 

6.11 Governing Law; Dispute Resolution. This Agreement will be governed by the laws of the State of Texas without regard to conflict of
law principles. In the event of any dispute between the Issuer on the one hand, and MD Anderson on the other (a “Dispute”), the parties agree that such Dispute shall be first submitted for resolution for a period of ten
(10) calendar days to designated senior officers of each of the parties who hold legal authority to resolve and settle such dispute. If any Dispute cannot be resolved and settled within such period, then to the extent authorized by the law
governing the power and authority of each party, the parties agree to submit such Dispute to full and binding arbitration that will be undertaken and conducted under the auspices of the American Arbitration Association by a panel of three
(3) arbitrators pursuant to that organization’s Commercial Arbitration Rules then in effect, as modified by and subject to the following terms: 

(a) MD Anderson, on the one hand, and the Issuer, on the other, will each choose one arbitrator and those two arbitrators will select the
third arbitrator. 

  
 15 

 (b) The fees and expenses of the arbitrators shall be borne in equal shares by the parties. 

(c) Each party shall bear the fees and expenses of its legal representation in the arbitration. 

(d) The arbitral tribunal shall not reallocate either the fees and expenses of the arbitrators or of the parties’ legal representation.

 (e) The arbitration shall be held in Nashville, Tennessee, USA which shall be the seat of the arbitration. 

(f) The arbitrators may not award, and no party may seek, indirect, incidental, consequential, punitive, exemplary, special, or enhanced
damages, or prejudgment interest, or attorneys’ fees or costs, nor may the arbitrators apply any multiplier to any award of actual damages, except as may be required by statute. 

(g) The arbitrators must issue a reasoned award, setting forth the arbitrators’ findings of fact and conclusions of law. 

(h) The award of the arbitrators may be entered in any court of competent jurisdiction. The award rendered by the arbitrators shall be final
and binding on the parties, except that the award is subject to limited judicial review and vacatur for the following reasons only: (i) the award was procured by corruption, fraud, or undue means, (ii) the award was tainted by evidence of
partiality or corruption by any of the arbitrators, (iii) the award was tainted by misconduct by any of the arbitrators, (iv) the arbitrators exceeded their powers, and/or (v) the award evidences a manifest disregard of the law or is
contrary to public policy. If the parties are unable to resolve a Dispute through binding arbitration, then any lawsuit pertaining to such Dispute that is brought by one party against another must be presented to and decided by a state or federal
court in the home locale of the defendant party (that being Houston, Texas for MD Anderson, and Germantown, Maryland for the Issuer). 

6.12 Counterparts; Execution. This Agreement may be executed in three (3) or more counterparts, each of which shall be deemed an
original, but all of which together shall constitute one and the same instrument. Counterparts may be delivered via facsimile, electronic mail (including pdf or any electronic signature complying with the U.S. federal ESIGN Act of 2000, e.g.,
www.docusign.com) or other transmission method and any counterpart so delivered shall be deemed to have been duly and validly delivered and be valid and effective for all purposes. 

6.13 Severability. If any provision hereof should be held invalid, illegal or unenforceable in any respect, then, to the fullest extent
permitted by law, (a) all other provisions hereof shall remain in full force and effect and shall be liberally construed in order to carry out the intentions of the parties as nearly as may be possible and (b) the parties shall use their best
efforts to replace the invalid, illegal or unenforceable provision(s) with valid, legal and 

  
 16 

 
enforceable provision(s) which, insofar as practical, implement the purposes of such provision(s) in this Agreement.
