Energy Spectrum Partners LP ("Energy Spectrum"), Munawar H. Hidayatallah, Saeed
M. Sheikh and Jens H. Mortensen (Messrs. Hidayatallah, Sheikh, and Mortensen are
collectively referred to as the "Directors Group") entered into a stockholders
agreement dated April 2, 2004 (the "Stockholders Agreement") pursuant to which
the parties have agreed to vote for the election to the board of directors of
the Issuer three persons nominated by Energy Spectrum, two persons nominated by
the Investors Group and one person nominated by the Directors Group. In
addition, the parties and the Issuer agreed that in the event the Issuer has not
completed a public offering of its shares prior to September 30, 2005, then, at
the request of Energy Spectrum, the Issuer will retain an investment banking
firm to identify candidates for a transaction involving the sale of the Issuer
or its assets. Moreover, Energy Spectrum, the Investors Group and the Directors
Group entered into a registration rights agreement with Issuer and other parties
named therein dated April 2, 2004 (the "Registration Rights Agreement"),
pursuant to which the parties were granted certain registration rights with
respect to the Common Stock owned or to be owned by such parties.

         On April 2, 2004 the Issuer issued to each of Messrs. Toboroff and
Nederlander A) 10,000 shares of Common Stock and B) an option to purchase
additional 10,000 shares of Common Stock (the "Toboroff Option" and the
"Nederlander Option," respectively), exercisable for $0.55 per share with a term
of five years, pursuant to the Issuer's 2003 Stock Incentive Plan. The shares
and options were issued to Messrs. Toboroff and Nederlander in lieu of fees for
their services as directors in 2002 and 2003.

         Each of the Reporting Persons acquired shares of Common Stock as an
investment. Each of the Reporting Persons may seek to acquire or dispose of
shares of Common Stock through open market or privately negotiated transactions
from time to time in its or his discretion. Any such purchases will depend upon
the market prices for the shares of Common Stock, the number of shares which may
become available for purchase at prices which each of the Reporting Persons
regard as attractive and various other factors which each of the Reporting
Persons may determine to be relevant.

         Except for the foregoing, no Reporting Person has any present plans or
proposals which relate to or would result in any of the actions or events
described in paragraphs (a) through (j) of Item 4 of Schedule 13D. However, the
Reporting Persons retain their respective rights to modify their plans with
respect to the transactions described in this Item 4, to acquire or dispose of

in the occurrence of any such events, subject to applicable laws and
regulations.
