Proxy Advisory Firm Glass Lewis Recommends That VAALCO Stockholders Do Not Vote for Any of Nanes Delorme Partners' and Pilatus Energy's Nominees

VAALCO Reiterates Commitment to Request Stockholder Ratification of Stockholder Rights Plan at 2009 Annual Meeting

HOUSTON--(BUSINESS WIRE)--

VAALCO Energy, Inc. (NYSE: EGY) today announced that Glass Lewis & Co., an independent proxy advisory firm, recommends that VAALCO stockholders vote on the Company's WHITE proxy card and do NOT vote for any of Nanes Delorme Partners' and Pilatus Energy's director nominees at the Company's upcoming Annual Meeting of Stockholders on June 4, 2008. VAALCO's Board unanimously recommends stockholders vote FOR all of the Company's incumbent director nominees - William S. Farish, Arne R. Nielsen and W. Russell Scheirman - by signing, dating and returning the WHITE proxy card today.

    In its May 22, 2008 report, Glass Lewis states*:

    --  "...we are concerned that the Dissident's primary plan for
        improvement appears to be pursuing a sale of the Company."

    --  "In the absence of some credible suggestion (which is absent
        here) that the board is self-interested, ill informed,
        refusing to act, entrenched, or poor at its company oversight
        functions, we believe it is generally not a good idea for
        shareholders to substitute their judgment regarding the timing
        of strategic transactions for that of the board."

In its report, Glass Lewis noted that the Company had previously adopted a stockholder rights plan without putting the plan to a stockholder vote. However, VAALCO announced on May 21, 2008, that its Board of Directors has determined to submit the Company's stockholder rights plan for ratification at the Company's 2009 Annual Meeting of Stockholders. If stockholders do not ratify the rights plan, the rights plan will be terminated.

"VAALCO's Board and management team have a record of execution and delivering solid stockholder returns. Indeed, VAALCO's stock price has equaled or surpassed virtually all accepted E&P peer group stock performance indicators over each of the last 1, 3 and 5 year periods. With VAALCO's imminent drilling program, we are confident in our ability to maintain this record of value creation well into the future," said Robert L. Gerry, III, VAALCO's Chairman and CEO.

Mr. Gerry continued, "In contrast, Nanes Delorme Partners and its recently revealed secret partner, Pilatus Energy, have serious conflicts of interest. The criminal history associated with Pilatus Energy's purported leader also raises significant concerns to us. We believe electing even one of Nanes Delorme Partners' and Pilatus Energy's nominees would put stockholder value at risk. We strongly urge all VAALCO stockholders to protect their investment by voting on the WHITE proxy card today and discarding any materials they receive from Nanes Delorme Partners and Pilatus Energy."

If stockholders have any questions about how to vote their WHITE proxy, they should contact the firm assisting VAALCO in the solicitation of proxies: D.F. King & Co., Inc. toll-free at 800-901-0068 or collect at 212-269-5550.

The Securities and Exchange Commission generally permits oil and gas companies, in filings with the SEC, to disclose only proved reserves that a company has demonstrated by actual production or conclusive formation tests to be economically and legally producible under existing economic and operating conditions. In this letter, we describe volumes of oil that we believe may be discovered in the future through our existing exploration program. These amounts are not proved reserves as defined by the SEC. These estimates are by their nature more speculative than estimates of proved reserves and accordingly are subject to substantially greater risk of being actually realized by VAALCO.
