Valero Energy Corporation Recommends Rejection of Below-Market-Price Mini-Tender Offer by TRC Capital Corporation.

SAN ANTONIO -- Valero Energy Corporation (NYSE: VLO) has been notified of an unsolicited "mini-tender" offer by TRC Capital Corporation ("TRC") made to Valero Energy Corporation ("Valero") stockholders to purchase up to 5,000,000 shares of Valero common stock at a price of $16.55 per share. TRC's offer price represents a 4.22% discount below the closing price of Valero's common stock on November 10, 2009, on the New York Stock Exchange, the date of the offer, and the offer is for less than 1% of Valero's outstanding shares of common stock.

Valero recommends that stockholders do not tender their shares of Valero stock in response to TRC's unsolicited mini-tender offer because the offer price is below the current market price of Valero's common stock. If the offer were to expire today, Valero stockholders who tendered their shares would lose money compared to the amount they could make by selling their shares on the open market. Valero urges investors to obtain current market quotations for their shares of Valero common stock, to consult with their financial advisor, and to exercise caution with respect to TRC's offer. Valero is not associated in any way with TRC, the mini-tender offer, or the offer documentation. Valero stockholders who already have tendered their shares are advised that they may withdraw their shares by providing the written notice described in the TRC offering documents prior to the expiration of the offer, currently scheduled for 12:01 a.m. EST on December 11, 2009.

Valero understands that TRC has made such mini-tender offers for the shares of other companies. Mini-tender offers are third-party offers that seek less than five percent of a company's stock and thereby avoid many investor protections that apply to larger tender offers, including the filing of disclosure and other tender offer documents with the Securities and Exchange Commission ("SEC") and other procedures mandated by U.S. securities laws. The SEC has issued an investor alert regarding mini-tender offers, noting that in making the offers at below-market prices, "bidders are hoping that they will catch investors off guard if the investors do not compare the offer price to the current market price." The SEC's investor alert may be found on the SEC Website at www.sec.gov/investor/pubs/minitend.htm.
