MEXICO CITY, July 13, 2012 /PRNewswire/ — GRUPO PETROTEMEX, S.A. DE C.V. (the “Company”) announced today that it has commenced an offer to purchase (the “Tender Offer”) any and all outstanding 9.500% Senior Notes due 2014 (the “Existing Notes”) and a solicitation of consents (the “Consents”) to amend the indenture relating to the Existing Notes (the “Consent Solicitation”).

The Tender Offer

The Tender Offer will expire at 5:00 P.M., New York City Time, on August 10, 2012, unless extended (such time and date, as the same may be extended, the “Expiration Time”). Holders who validly tender Existing Notes at or prior to 5:00 P.M., New York City Time, on July 27, 2012, unless extended (such time and date, as the same may be extended, the “Early Tender and Consent Time”), will be eligible to receive the Total Consideration (as described below). Holders who validly tender Existing Notes after the Early Tender and Consent Time, but at or prior to the Expiration Time, will be eligible to receive the Tender Offer Consideration (as described below).

Holders of Existing Notes who validly tender Existing Notes in the Tender Offer and Consent Solicitation, and whose tender and delivery of Consents are accepted by the Company, will receive, in addition to accrued and unpaid interest, for each US$1,000 principal amount of Existing Notes tendered, an amount in cash in U.S. dollars equal to:

• in the case of Existing Notes tendered and related Consents delivered at or prior to the Early Tender and Consent Time, an amount equal to US$1,130 (the “Total Consideration”), consisting of (i) an amount equal to US$1,100 (the “Tender Offer Consideration”), plus (ii) an amount equal to US$30 (the “Early Tender Fee”) and
• in the case of Existing Notes tendered and related Consents delivered after the Early Tender and Consent Time, but at or prior to the Expiration Time, the Tender Offer Consideration.

The terms and conditions of the Tender Offer and Consent Solicitation are set forth in an offer to purchase and consent solicitation statement, dated July 13, 2012 (the “Offer to Purchase”). The Company may amend, extend or terminate the Tender Offer and Consent Solicitation.

The Consent Solicitation

Under the Consent Solicitation, the Company is soliciting Consents to amend the indenture relating to the Existing Notes (the “Proposed Amendments”). The Proposed Amendments, if approved, will eliminate substantially all of the Company’s restrictive covenants under the indenture relating to the Existing Notes.

Holders who desire to tender their Existing Notes must deliver Consents to the Proposed Amendments, and holders may not deliver Consents without tendering the related Existing Notes.

The completion of the Tender Offer and Consent Solicitation is conditioned on the valid delivery to the depositary appointed by the Company (named below) of the Consents of holders of at least a majority in principal amount of the outstanding Existing Notes at or prior to the Expiration Time.

Settlement

The Company expects that payment for all Existing Notes validly tendered prior to the Early Tender and Consent Time and accepted by the Company will be made on the business day or days the Company selects after the Early Tender and Consent Time (the “Early Settlement Date”).

Payment for all Existing Notes validly tendered after the Early Tender and Consent Time and at or prior to the Expiration Time and accepted by the Company will be made on the business day the Company selects promptly following the Expiration Time or the business day on which the Company waives the conditions to consummation of the Tender Offer and Consent Solicitation (the “Final Settlement Date”). The Company expects the Final Settlement Date (subject to any extension of the Expiration Time) to be August 15, 2012.
