MEXICO CITY, July 30, 2012 /PRNewswire/ — GRUPO PETROTEMEX, S.A. DE C.V. (the “Company”) announced results of its offer to purchase (the “Tender Offer”) any and all of its outstanding 9.500% Senior Notes due 2014 (the “Existing Notes”) and solicitation of consents (the “Consents”) to amend the indenture relating to the Existing Notes (the “Consent Solicitation”) upon the terms and conditions set forth in the Offer to Purchase and Consent Solicitation Statement dated as of July 13, 2012 (the “Offer to Purchase”).

As of 5:00 P.M., New York City Time, on July 27, 2012 (the “Early Tender and Consent Time”), U.S. $153,573,000 in aggregate principal amount of the Existing Notes, representing a majority in aggregate principal amount of Existing Notes, had been validly tendered and not withdrawn in the Tender Offer. In addition, the Company had obtained Consents to the Proposed Amendments (as defined in the Offer to Purchase) from holders representing a majority in aggregate principal amount of Existing Notes.

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 prior to the Expiration Time, will be eligible to receive only the Tender Offer Consideration and not the Total Consideration, both 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 U.S. $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 U.S. $1,130 (the “Total Consideration”), consisting of (i) an amount equal to U.S. $1,100 (the “Tender Offer Consideration”), plus (ii) an amount equal to U.S. $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 the Offer to Purchase. The Company may amend, extend or terminate the Tender Offer and Consent Solicitation.

Settlement

The Company expects that payment for all Existing Notes validly tendered at or prior to the Early Tender and Consent Time and accepted by the Company will be made on or about August 1, 2012 (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 on or about August 15, 2012.
