Re: Initial Public Offering

Gentlemen:

     The undersigned officer and director and stockholder of Energy Services
Acquisition Corp. ("COMPANY"), in consideration of Ferris, Baker Watts,
Incorporated ("FBW") entering into a letter of intent ("LETTER OF INTENT") to
underwrite an initial public offering of the securities of the Company ("IPO")
and embarking on the IPO process, hereby agrees as follows (certain capitalized
terms used herein are defined in paragraph 11 hereof):

     1. If the Company solicits approval of its stockholders of a Business
Combination, the undersigned will vote all shares of Common Stock of the
Company, including the Insider Shares and IPO Shares, owned by him in accordance
with the majority of the votes cast by the holders of the IPO Shares.

     2. The undersigned will escrow his Insider Shares until six months after
the consummation of a Business Combination subject to the terms of a Stock
Escrow Agreement which the Company will enter into with the undersigned and an
escrow agent acceptable to the Company.

     3. In the event that the Company fails to consummate a Business Combination
within 18 months from the effective date ("EFFECTIVE DATE") of the registration
statement relating to the IPO (or 24 months under the circumstances described in
the prospectus relating to the IPO), the undersigned will take all reasonable
actions within his power to cause the Company to liquidate as soon as reasonably
practicable. The undersigned hereby waives any and all right, title, interest or
claim of any kind ("CLAIM") in or to any distribution of the Trust Fund (as
defined in the Letter of Intent) with respect to his Insider Shares and waives
any Claim the undersigned may have in the future as a result of, or arising out
of, any contracts or agreements with the Company and will not seek recourse
against the Trust Fund for any reason whatsoever. The undersigned agrees to
indemnify and hold harmless the Company against any and all loss, liability,
claims, damage and expense whatsoever (including, but not limited to, any and
all legal or other expenses reasonably incurred in investigating, preparing or
defending against any litigation, whether pending or threatened, or any claim
whatsoever) which the Company may become subject to as a result of any claim by
any vendor that is owed money by the Company for services rendered or products
sold but only to the extent necessary to ensure that such loss, liability,
claim, damage or expenses does not reduce the amount in the Trust Fund.

     4. In order to minimize potential conflicts of interest which may arise
from multiple affiliations, the undersigned agrees to present to the Company for
its consideration, prior to presentation to any other person or entity, any
suitable opportunity to acquire an operating business, until the earlier of the
consummation by the Company of a Business Combination, the liquidation of the
Company or until such time as the undersigned ceases to be an officer or
director of the Company, subject to any pre-existing fiduciary obligations the
undersigned might have, including, but not limited to, the undersigned's
obligation to present business opportunities to ________________.

perspective.
