VAALCO Energy Reviews Board's Record of Superior Operating, Financial and Stock Price Performance in Investor Presentation

Reviews Risks Associated with Nanes Delorme Partners, Pilatus Energy and Their Nominees Urges Stockholders to Support VAALCO's Board by Voting the WHITE Proxy Card Today

HOUSTON--(BUSINESS WIRE)--

VAALCO Energy, Inc. (NYSE: EGY) today announced that it has filed an investor presentation with the Securities and Exchange Commission in connection with the Company's 2008 Annual Meeting of Stockholders, which is scheduled for June 4, 2008. The investor presentation is available in the "Latest News" section of the Company's website at http://www.vaalco.com/ or at the SEC's website at www.sec.gov.

The presentation includes data and facts that VAALCO believes demonstrate that:

    -- VAALCO's Board has an exceptional track record and expertise,
     including superior stock price, operating and financial
     performance:

        -- 503% cumulative stockholder return over the last 5 years(1)

        -- Stock price appreciation that has outperformed VAALCO's
         peer group(2) over each of the last 6-month, 1-year, 3-year
         and 5-year periods

        -- 31% 5-year average ROIC (among top 5% of the oil & gas
         industry)

        -- 66% revenue CAGR over the last 5 years (#1 among peers)

        -- 81% EBITDA CAGR over the last 5 years (#2 among peers)

        -- 82% success rate in exploration drilling since 1998, when
         Etame drilling began (among the best in the industry)

        -- 100% success rate in the drilling and completion of
         development wells since 1998 (among the best in the industry)

        -- 50% increase in production since 2002

    -- VAALCO's current exploration program represents the highest
     level of exploration and development in the Company's history

    -- Nanes Delorme Partners' arguments rest on a variety of
     incorrect assertions

    -- Even one of Nanes Delorme Partners' and Pilatus Energy's
     nominees is bad for VAALCO stockholders because:

        -- Nanes Delorme Partners and Pilatus Energy have significant
         conflicts of interest

        -- Nanes Delorme Partners and Pilatus Energy offer no
         substantive ideas other than a sale or break-up of the
         Company

        -- Nanes Delorme Partners' and Pilatus Energy's nominees add
         no significant skills or experience

    -- VAALCO's nominees are the right choice to help support
     continued value creation

"VAALCO's Board has driven superior operating, financial and stock price performance. Importantly, we are also well-positioned to build on the exceptional track record that VAALCO's Board and management have established," said Robert L. Gerry, III, VAALCO's Chairman and CEO. "We believe that allowing even one of Nanes Delorme Partners' and Pilatus Energy's nominees onto VAALCO's Board would risk stockholder value and the future of VAALCO. We urge 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."

VAALCO's Board unanimously recommends stockholders vote "FOR" all three of the Company's highly qualified and experienced directors - William S. Farish, Arne R. Nielsen and W. Russell Scheirman - by signing, dating and returning the WHITE proxy card.

This document includes "forward-looking statements" as defined by the U.S. securities laws. Forward-looking statements are those concerning VAALCO's plans, expectations, and objectives for future drilling, completion and other operations and activities. All statements included in this document that address activities, events or developments that VAALCO expects, believes or anticipates will or may occur in the future are forward-looking statements. These statements include future production rates, completion and production timetables and costs to complete well. These statements are based on assumptions made by VAALCO based on its experience perception of historical trends, current conditions, expected future developments and other factors it believes are appropriate in the circumstances. Such statements are subject to a number of assumptions, risks and uncertainties, many of which are beyond VAALCO's control. These risks include, but are not limited to, inflation, lack of availability of goods, services and capital, environmental risks, drilling risks, foreign operational risks and regulatory changes.

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.
