                            STOCK PURCHASE AGREEMENT

     THIS STOCK PURCHASE AGREEMENT is dated as of January 10, 2002, by and among
Esslinger-Wooten-Maxwell, Inc. (the "Purchaser"), First Reserve, Inc. (the
"Company") and Charles Manni (the "Seller").

     WHEREAS, the Purchaser wishes to purchase, and the Seller is willing to
sell, 1,778,825 shares of the outstanding common stock of the Company (the
"Shares") from the Seller in exchange for the Purchase Price (as herein
defined), subject to the terms and conditions contained in this Agreement;

     NOW THEREFORE, in consideration of the mutual covenants contained herein
and other good and valuable consideration, the receipt and sufficiency of which
are hereby acknowledged, the parties agree that the foregoing recitals are true
and correct and further agree as follows:

     1.   Purchase and Sale. On the Closing (as defined herein), the Seller
shall sell, assign, transfer, convey and deliver the Shares to the Purchaser,
free and clear of any and all liens, claims and encumbrances, and the Seller
shall evidence such transaction by delivering to the Purchaser certificates for
the Shares along with stock power(s) duly endorsed in blank, in the name of the
Purchaser, with all applicable documentary stamp and/or transfer taxes paid by
the Seller.

     2.   Consideration. In consideration of the conveyance of the Shares to the
Purchaser, at the Closing the Purchaser shall deliver to the Seller $3,500,000
(the "Purchase Price") in cash (by bank check or wire transfer of funds). The
Purchaser shall also purchase an additional 127,059 shares of the common stock
of the Company currently owned by the Seller for $250,000 in cash on or prior to
the 30/th/ day following the Closing. In addition, the Purchaser shall purchase
the balance of the shares of the common stock of the Company owned by the Seller
(254,117 shares) for $500,000 in cash on or prior to June 30, 2002.

     3.   Option. The Company hereby grants to the Seller an option (the
"Option") to purchase up to 5% of the then-outstanding shares of common stock of
the Company (the "Option Shares") at a purchase price equal to the product of
90% of the "fair market value" of one share of the Company's common stock times
the amount of Option Shares, the total of which shall be payable in cash by the
Seller to the Company upon delivery of such Option Shares. The Option shall be
exercisable by the Seller on or before June 30, 2007, by notice in writing to
the Company at the address set forth herein. As used in this Section, the term
"fair market value" shall mean, (i) if the common stock of the Company is
"publicly traded" in a U.S. market, then the weighted average closing bid price
for the five immediately preceding trading days, or (ii) if alternative (i) is
not available, then the per share purchase price involved in the most recent
(from the date of the exercise of this Option) closing of an arm's length, third
party private sale or purchase of the common stock of the Company by the
Company, Allen C. Harper or Ronald A. Shuffield. Any dispute regarding the
determination of the "fair market value" of the

<PAGE>

Company shall be resolved by the Company's independent certified public
accountants and their decision shall be final and binding.

          In connection with the granting of the Option, any and all other
options, warrants or other agreements to purchase shares of the common stock of
the Company held by the Seller and/or any of his affiliates are hereby cancelled
and of no further force and effect. Without limiting the generality of the
foregoing, those certain First Reserve, Inc. Common Stock Purchase Warrants (to
purchase up to 1,000,000 shares of common stock of the Company), dated as of
August 31, 1998, issued in the name of VALORSEC Verwaltungs & Treu-Anstalt are
hereby cancelled and of no further force and effect.

     4.   Closing. The closing of the purchase and sale of the Shares shall
occur by courier, e.g., Federal Express or similar delivery service, on or about
April 30, 2002, unless the parties mutually agree in writing to another date
(the "Closing").
