Execution Copy

Licensee shall bear all costs and expenses associated with meeting regulatory standards. Licensee shall also comply fully with all other applicable laws, rules and regulations including those of the United States.

23.2 Licensee has represented and warranted to PA, and hereby reaffirms its representation that, other than as disclosed on
Schedule 23.2 attached hereto or in this Section below, no Affiliate, director, employee, or direct or indirect owner of Licensee, or any representative, consultant or agent of Licensee who will be involved in Licensees
performance of the License Agreement or the project contemplated under that agreement, is a government official, political party official or candidate, or a close family member or designee of such an official or candidate (any such involvement by
any of the aforementioned parties, a Governmental Relationship), and that any Government Relationship disclosed on Schedule 23.2 or in this Section below will not cause the Licensee, or PA, to violate the laws of the
country in which made or the laws of the United States or the laws of any other relevant jurisdiction (the Anti-Corruption Laws), or violate Licensees obligations hereunder (including without limitation this Section). In the event
that during the Term of this Agreement there is a change in the information contained in this paragraph, or any change in the financial or ownership interests in or management of Licensee, Licensee agrees to make immediate disclosure to PA. If, in
PAs sole and absolute discretion, PA determines that such change substantially increases the risks of a violation of the Anti-Corruption Laws arising from its relationship with Licensee or this Agreement, PA shall give written notice to
Licensee of such determination and Licensee shall have a reasonable period of time, but no more than thirty (30) days thereafter, to terminate and sever its relationship with the Affiliate, owner, officer, director, etc., who has the offending
Government Relationship. If Licensee fails to terminate and sever such Government Relationship. PA may immediately terminate the Agreement as a for-cause termination under Section 14.3.

In the event that PA becomes aware of any Government Relationship of any Affiliate, owner, officer, director, employee, agent, consultant, or
representative of Licensee or any Sub-licensee which substantially increases the risks of a violation of the Anti-Corruption Laws by PA arising from its relationship with Licensee, PA shall notify Licensee of this relationship and Licensee will, no
later than two (2) days after receiving such notification, provide PA with an explanation of such relationship. Thereafter, if required by PA (in its sole and absolute discretion), Licensee shall have a reasonable period of time, but no more
than ten (10) days, to terminate and sever its relationship with the Affiliate, owner, officer, director, etc. who has the offending Government Relationship. If Licensee fails to terminate and sever such Government Relationship, PA may
immediately terminate the Agreement as a for-cause termination under Section 14.3.

Notwithstanding the above, the parties
acknowledge that * and other companies and enterprises in the energy sector in the Peoples Republic of China are state or quasi-state enterprises and the central government of the Peoples Republic of China has control over strategic
industries such as the oil and energy industry. Therefore, if any Government Relationship is reasonably necessary for Licensee to satisfy Section 9.2.4 (which *), then, in such a case, Licensee will provide an explanation of such Governmental
Relationship prior to entering into such Governmental Relationship and PA will determine whether, in its sole

and absolute discretion, such Government Relationship may be entered into by Licensee. In the event that PA decides that such Governmental Relationship may not be entered into by Licensee due to the fact that it
substantially increases the risks of a violation of the Anti-Corruption Laws which may arise hereunder or from PAs relationship with Licensee, and, without such Governmental Relationship, Licensee is unable to fulfill its obligations under
Section 9.2.4, then PA may either waive the requirement regarding the *, or require Licensee, within a reasonable period of time (but no more than thirty (30) days), to terminate and sever such Government Relationship. If PA has required
termination of such Government Relationship, and Licensee does not do so, then PA may immediately terminate the Agreement as a for-cause termination under Section 14.3.

23.3 Notwithstanding anything else in this Agreement to the contrary, Licensee affirms that it, or its Affiliates, have not and will not, in connection
with the actions contemplated by this Agreement or in connection with any other business involving PA, make, offer, promise, agree to make or authorize any payment or transfer of anything of value, directly or indirectly to: (i) any Government
Official; (ii) any political party, party official or candidate; (iii) any person while knowing or having reason to know that all or a portion of the value will be offered, given or promised, directly or indirectly, to anyone described in
items (i) or (ii) above; (iv) any owner, director, employee, representative or agent of any actual or potential customer or Sublicensee of Licensee; (v) any director, employee, representative or agent of PA or any of its
affiliates; or (vi) any other person or entity, if such payment or transfer would violate the laws of the country in which made or the laws of the United States or the laws of any other relevant jurisdiction. It is the intent of the parties
that no payments or transfers of value shall be made which have the purpose or effect of public or commercial bribery, acceptance of or acquiescence in extortion, kickbacks or other unlawful or improper means of obtaining business or any improper
advantage. This Section does not, however, prohibit the providing of reasonable and customary meals and entertainment in the normal course of business or the giving of business mementos of nominal value.



|8. | The Licensee will establish, within * of execution of this amendment,*. The * will be * upon completion of the following: (1) *, and (2) *, which will not be unreasonably withheld.
|-- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|9. | Except as expressly amended and modified in this Amendment, the terms and conditions set forth under the Master License Agreement shall remain in full force and effect.
