                                      Summary of Significant Accounting Policies
================================================================================

Income taxes             The Company follows Statement of Financial Accounting
                         Standards No. 109("SFAS No. 109"), "Accounting for
                         Income Taxes" which is an asset and liability approach
                         that requires the recognition of deferred tax assets
                         and liabilities for the expected future tax
                         consequences of events that have been recognized in the
                         Company's financial statements or tax returns.

Net income per share     Net income per share is computed on the basis of the
                         weighted average number of common shares outstanding
                         during the period, including common stock equivalents
                         (unless anti-dilutive) which would arise from the
                         exercise of stock warrants.

Use of estimates         The preparation of financial statements in conformity
                         with accounting principles generally accepted in the
                         United States of America requires management to make
                         estimates and assumptions that affect the report
                         amounts of assets and liabilities at the date of the
                         financial statements and the reported amounts of
                         expenses during the reporting period. Actual results
                         could differ from those estimates.

Reclassifications        Certain items have been reclassified from prior periods
                         to conform with current period presentation.

                                         Notes to Unaudited Financial Statements
================================================================================

1. Basis of Presentation    The accompanying financial statements are unaudited
                            and have been prepared in accordance with accounting
                            principles generally accepted in the United States
                            of America for interim financial information and
                            with instructions to Form 10-QSB. Accordingly,
                            certain information and footnote disclosures
                            normally included in financial statements prepared
                            in accordance with accounting principles generally
                            accepted in the United States of America have been
                            omitted pursuant to such rules and regulations.
                            These financial statements should be read in
                            conjunction with the financial statements that were
                            included in the Company's Annual Report on Form
                            10-KSB for the period ended December 31, 2004.

                            In the opinion of management, all adjustments
                            (consisting of normal accruals) have been made that
                            are necessary to present fairly the financial
                            position of Tremisis Energy Acquisition Corporation
                            (the "Company"). Operating results for the interim
                            period presented are not necessarily indicative of
                            the results to be expected for a full year.

2. Organization and 
   Business Operations      The Company was incorporated in February 5, 2004 as
                            a blank check company whose objective is to acquire
                            an operating business in either the energy or the
                            environmental industry and their related
                            infrastructures.

                            The registration statement for the Company's initial
                            public offering ("Offering") was declared effective
                            May 13, 2004. The Company consummated the offering
                            on May 18, 2004 and received net proceeds of
                            approximately $34,163,100 (Note 3). The Company's
                            management has broad discretion with respect to the
                            specific application of the net proceeds of this
                            Offering, although substantially all of the net
                            proceeds of this Offering are intended to be
                            generally applied toward consummating a business
                            combination with an operating business in the energy
                            and environmental industry and their related

                            30, 2005 an amount of $33,844,401 (which includes
                            accrued interest of $18,361) is being held in an
                            interest-bearing trust account ("Trust Fund") until
                            the earlier of (i) the consummation of its first

================================================================================

                            The Company, after signing a definitive agreement
                            for the acquisition of a target business, will
                            submit such transaction for stockholder approval. In
                            the event that stockholders owning 20% or more of
                            the shares sold in the Offering, vote against the
                            Business Combination and exercise the conversion
                            rights described below, the Business Combination
                            will not be consummated. All of the Company's
                            stockholders prior to the Offering, including all of
                            the officers and directors of the Company ("Initial
                            Stockholders"), have agreed to vote their 1,375,000
                            founding shares of common stock in accordance with
                            the vote of the majority in interest of all other
                            stockholders of the Company ("Public Stockholders")
                            with respect to the Business Combination. After
                            consummation of the Business Combination, all of
                            these voting safeguards will no longer be
                            applicable.

                            With respect to a Business Combination which is
                            approved and consummated, any Public Stockholder who
                            voted against the Business Combination may demand
                            that the Company convert his or her shares. The per
                            share conversion price will equal the amount in the
                            Trust Fund as of the record date for determination
                            of stockholders entitled to vote on the Business
                            Combination divided by the number of shares of
                            common stock held by Public Stockholders at the
                            consummation of the Offering. Accordingly, Public
                            Stockholders holding 19.99% of the aggregate number
                            of shares owned by all Public Stockholders may seek
                            conversion of their shares in the event of a
                            Business Combination. Such Public Stockholders are
                            entitled to receive their per share interest in the
                            Trust Fund computed without regard to the shares
                            held by Initial Stockholders. In this respect,
                            $6,765,498 and $6,685,164 (which includes accretion
                            of Trust Fund) has been classified as common stock
                            subject to possible conversion at June 30, 2005 and
                            December 31, 2004, respectively.

                            The Company's Certificate of Incorporation provides
                            for mandatory liquidation of the Company in the
                            event that the Company does not consummate a
                            Business Combination within 18 months from the date
                            of the consummation of the Offering (such date would
                            be November 18, 2005), or 24 months from the
                            consummation of the Offering (such date would be May
                            18, 2005) if certain extension criteria have been
                            satisfied. In the event of liquidation, it is likely
                            that the per share value of the residual assets
                            remaining available for distribution (including
                            Trust Fund assets) will be less than the initial
                            public offering price per share in the Offering
                            (assuming no value is attributed to the Warrants
                            contained in the Units sold in the Offering
                            discussed in Note 3).

                            Warrants ("Warrants"). Each Warrant will entitle the
                            holder to purchase from the Company one share of
                            common stock at an exercise price of $5.00

                            will be redeemable at a price of $.01 per Warrant
                            upon 30 days' notice after the Warrants become
                            exercisable, only in the event that the last sale

                            share for any 20 trading days within a 30 trading
                            day period ending on the third day prior to the date
                            on which notice of redemption is given. In

                            for $100, an option to the representative of the

                            warrants underlying such Units are exercisable at
                            $6.25 per share.

ITEM 2 - MANAGEMENT'S DISCUSSION AND ANALYSIS OR PLAN OF OPERATION

The following discussion should be read in conjunction with the Company's
Consolidated Financial Statements and footnotes thereto contained in this
report.

Forward Looking Statements

      The statements discussed in this Report include forward looking statements
that involve risks and uncertainties detailed from time to time in the Company's
reports filed with the Securities and Exchange Commission.

Plan of Operations

      We were formed on February 5, 2004 to serve as a vehicle to effect a
merger, capital stock exchange, asset acquisition or other similar business
combination with a company in the either of the energy or environmental
industries and their related infrastructures. We intend to utilize cash derived
from the proceeds of our recently completed public offering, our capital stock,
debt or a combination of cash, capital stock and debt, in effecting a business
combination.

      Net income for the three months ended June 30, 2005 consisted Interest
income of $223,812 reduced by $10,500 for a monthly administrative services
agreement, $24,052 for professional fees, $14,647 for officer liability
insurance, $11,732 for travel, meals and entertainment expenses, $7,788 for
franchise fees, $73,850 for taxes and $12,190 for other expenses.

      Net income for the three months ended June 30, 2004 consisted Interest
income of $52,666 reduced by $7,000 for a monthly administrative services
agreement, $1,125 for professional fees, $7,375 for officer liability insurance,
$5,564 for travel, meals and entertainment expenses and $40,103 for other
expenses.

      Net income for the six months ended June 30, 2005 consisted Interest
income of $407,209 reduced by $21,000 for a monthly administrative services
agreement, $62,031 for professional fees, $29,397 for officer liability
insurance, $66,387 for travel, meals and entertainment expenses, $15,282 for
franchise fees, $107,150 for taxes and $18,026 for other expenses.

      Net income for the period from February 5, 2004 (inception) to June 30,
2004 consisted Interest income of $52,666 reduced by $7,000 for a monthly
administrative services agreement, $1,125 for professional fees, $7,375 for
officer liability insurance, $5,564 for travel, meals and entertainment expenses
and $40,953 for other expenses

      Net income for the period from February 5, 2004 (inception) to June 30,
2005 consisted of Interest income of $715,241 reduced by $49,000 for a monthly
administrative services agreement, $81,517 for professional fees, $66,272 for
officer liability insurance, $71,816 for travel, meals and entertainment
expenses, $38,282 for franchise fees, $186,265 for taxes and $69,628 for other
expenses.

      We consummated our initial public offering on May 18, 2004. Gross proceeds
from our initial public offering, including the full exercise of the
underwriters' over-allotment option, were $37,950,100. After deducting offering
expenses of $1,510,000 including $990,000 evidencing the underwriters'
non-accountable expense allowance of 3% of the gross proceeds, and underwriting
discounts of $2,277,000, net proceeds were $34,163,100. $33,844,401 (which
includes accrued interest of $18,361) is currently held in trust and the
remaining proceeds are available to be used to provide for business, legal and
accounting due diligence on prospective acquisitions and continuing general and
administrative expenses. We will use substantially all of the net proceeds of
this offering to acquire a target business, including identifying and 


                                       12


evaluating prospective acquisition candidates, selecting the target business,
and structuring, negotiating and consummating the business combination. To the
extent that our capital stock is used in whole or in part as consideration to
effect a business combination, the proceeds held in the trust fund as well as
any other net proceeds not expended will be used to finance the operations of
the target business. We believe that we have sufficient available funds outside
of the trust fund to operate through May 18, 2006, assuming that a business
combination is not consummated during that time. Over this time period, we
anticipate approximately $180,000 of expenses for legal, accounting and other
expenses related to the due diligence investigations, structuring and
negotiating of a business combination, $84,000 for the administrative fee
payable to First Americas Management LLC ($3,500 per month for two years),
$50,000 of expenses for the due diligence and investigation of a target
business, $40,000 of expenses in legal and accounting fees relating to our SEC
reporting obligations and $666,000 for general working capital that will be used
for miscellaneous expenses and reserves, including approximately $60,000 for
director and officer liability insurance premiums. We do not believe we will
need to raise additional funds following this offering in order to meet the
expenditures required for operating our business. However, we may need to raise
additional funds through a private offering of debt or equity securities if such
funds are required to consummate a business combination that is presented to us.
We would only consummate such a fund raising simultaneously with the
consummation of a business combination.

      We are obligated to pay to First Americas Management LLC, an affiliate of
Isaac Kier, our secretary, treasurer and a member of our board of directors, a
monthly fee of $3,500 for general and administrative services. Through June 30,
2005, an aggregate of $49,000 has been paid for such services. In addition, in
February and April 2004, Lawrence S. Coben advanced an aggregate of $77,500 to
us, on a non-interest bearing basis, for payment of offering expenses on our
behalf. This amount was repaid in May 2004 out of proceeds of our initial public
offering.

ITEM 3. CONTROLS AND PROCEDURES.

      An evaluation of the effectiveness of our disclosure controls and
procedures as of June 30, 2005 was made under the supervision and with the
participation of our management, including chief executive officer and

ITEM 2: UNREGISTERED SALES OF EQUITY SECURITIES AND USE OF PROCEEDS

      On May 18, 2004, we closed our initial public offering of 6,325,000 Units,
including 825,000 Units issued upon exercise of the underwriters' over-allotment
option, with each unit consisting of one share of our common stock and two
warrants, each to purchase one share of our common stock at an exercise price of
$5.00 per share. The Units were sold at an offering price of $6.00 per Unit,
generating gross proceeds of 37,950,100. The representative of the underwriters
in the offering was EarlyBirdCapital, Inc. The securities sold in the offering
were registered under the Securities Act of 1933 on a registration statement on
Form S-1 (No. 333-113583). The Securities and Exchange Commission declared the
registration statement effective on May 12, 2004.

      We paid a total of $2,277,000 in underwriting discounts and commissions,
and $1,510,000 for costs and expenses related to the offering, including
$990,000 for the underwriters' non-accountable expense allowance of 3% of the
gross proceeds.

      After deducting the underwriting discounts and commissions and the
offering expenses, the total net proceeds to us from the offering were
$34,163,100, of which $33,143,000 was deposited into a trust fund and the
remaining proceeds are to be used to provide for business, legal and accounting
due diligence on prospective business combinations and continuing general and
administrative expenses. Through June 30, 2005, we have used approximately
$454,000 of cash for operating expenses and $77,500 to repay advances made to us
by one of our initial stockholders.
