follows: 
 SECTION 1. Upon the occurrence of the Consent Solicitation Completion Date (as defined below), the text of Section 9(j) of
the terms and conditions of the 2023 Bonds shall be amended and restated in its entirety as follows: 
 Control: PEMEX shall cease to
be a public-sector entity of the Government or the Government shall otherwise cease to control PEMEX or any Guarantor; or PEMEX or any of the Guarantors shall be dissolved, disestablished or shall suspend its respective operations, and such
dissolution, disestablishment or suspension of operations is material in relation to the business of PEMEX and the Guarantors taken as a whole; or PEMEX, the Guarantors and entities that they control shall cease to be, in the aggregate, the
primary public-sector entities which conduct on behalf of Mexico the activities of exploration, extraction, refining, transportation, storage, distribution and first-hand sale of crude oil and exploration, extraction, production and
first-hand sale of gas; for purposes of this provision, the term “primary” shall refer to the production of at least 75% of the barrels of oil equivalent of crude oil and gas produced by public-sector entities in Mexico;

effective as delivery of a manually executed counterpart hereof. 
 SECTION 5. This Consent Amendment shall be governed by, and construed in
accordance with, the law of the State of New York.

in respect of the validity or sufficiency of this Consent Amendment or for or in respect of the recitals contained herein, all of which recitals are made solely by Petróleos Mexicanos.
