                                         Tremisis Energy Acquisition Corporation
                                        (a corporation in the development stage)

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

Cash and Cash Equivalents     The Company considers all highly liquid
                              investments with original maturities of three
                              months or less to be cash equivalents.


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. The Company
                              has an income tax payable of approximately
                              $21,200.

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 reported 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.

Furniture and Equipment       Furniture and equipment is stated at cost, net of
                              accumulated depreciation. Depreciation is computed
                              on a straight line basis over the estimated lives
                              of 5 to 7 years commencing upon the date the asset
                              is placed in service.

1.    Basis of Presentation   The financial statements are unaudited and include
                              the accounts of Tremisis Energy Acquisition
                              Corporation (a corporation in the development

                              In the opinion of management, all adjustments
                              (consisting primarily of normal accruals) have
                              been made that are necessary to present fairly the
                              financial position of the Company as of September
                              30, 2004 and the results of its operations and its
                              cash flows for the periods ended September 30,
                              2004. Operating results for the interim period
                              presented are not necessarily indicative of the
                              results to be expected for a full year. The
                              Company has selected December 31st as its fiscal
                              year end.

                              The statements and related notes have been
                              prepared pursuant to the rules and regulations of
                              the U.S. Securities and Exchange Commission.
                              Accordingly, certain information and footnote
                              disclosures normally included in financial
                              statements prepared in accordance with generally
                              accepted accounting principles 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 Current Report on Form 8-K filed
                              on May 18, 2004.



2.    Organization and
      Business Operations     The Company was incorporated in Delaware on
                              February 5, 2004 as a blank check company, the
                              objective of which is to acquire an operating
                              business in either the energy or the environmental
                              industry and their related infrastructures. The
                              Company's initial stockholders purchased 1,375,000
                              common shares, $.0001 par value, for $25,000 on
                              February 5, 2004.

                              On May 18, 2004, the Company consummated an
                              Initial Public Offering ("Offering") and raised
                              net proceeds of $34,163,000 which is discussed in
                              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 a
                              operating business in either the energy or
                              environmental industry and their related
                              infrastructures ("Business Combination").
                              Furthermore, there is no assurance that the
                              Company will be able to successfully effect a
                              Business Combination. An amount of $33,300,953
                              (which includes accrued interest of $157,953) is
                              being held in an interest bearing trust account
                              ("Trust Fund") until the earlier of (i) the
                              consummation of its first Business Combination or
                              (ii) liquidation of the Company. Under the
                              agreement governing the Trust Fund, funds will
                              only be invested in United Stated government
                              securities (treasury bills) with a maturity of 180
                              days or less. The remaining net proceeds (not held
                              in trust) may be used to pay for business, legal
                              and accounting due diligence on prospective
                              acquisitions and continuing general and
                              administrative expenses.

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

                              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 stock sold in the Offering, vote against
                              the Business Combination and exercise their
                              redemption 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
                              any Business Combination. After consummation of
                              the Company's first 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 shares. The
                              per share redemption 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 Proposed Offering.
                              Accordingly, Public Stockholders holding 19.99% of
                              the aggregate number of shares owned by all Public
                              Stockholders may seek redemption 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, $6,448,277 has been
                              classified as common stock subject to possible
                              redemption.

                              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, or 24
                              months from the consummation of the Offering 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 due to
                              costs related to the Offering (assuming no value
                              is attributed to the warrants contained in the
                              Units in the Offering discussed in Note 3).

3.    Offering                The Company sold 6,325,000 units ("Units") in the
                              Offering, which includes all of the 825,000 Units
                              subject to the underwriters' over allotment
                              option. Each Unit consists of one share of the
                              Company's common stock, $.0001 par value, and two

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

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, including the timely delivery and
acceptance of the Company's products and the other risks 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 September 30, 2004 consisted of
interest income on the Trust Fund investment of $107,176, interest on cash and
cash equivalents of $3,400 offset by general and administration expenses of
$10,500 expense for a monthly administrative services agreement, $5,183 for
professional fees, $14,750 expense for officer liability insurance, $1,729 for
travel expenses, $21,200 in income tax payable and $8,495 for other expenses

      Net income for the period from February 5, 2004 (inception) to September
30, 2004 consisted of interest income on the Trust Fund investment of $157,953,
interest on cash and cash equivalents of $5,289 offset by general and
administration expenses of $17,500 expense for a monthly administrative services
agreement, $7,443 for professional fees, $22,125 expense for officer liability
insurance, $4,518 for travel expenses, $21,200 in income tax payable and $51,088
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 $37,950,000. 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 $34,163,000. Of this amount,
$33,300,953 (which includes accrued interest of $157,953) is being 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 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


                                       11


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.

      Commencing May 12, 2004, we 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. 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 September 30, 2004 was made under the supervision and with the
participation of our management, including chief executive officer and
treasurer. Based on that evaluation, he concluded that our disclosure controls
and procedures are effective as of the end of the period covered by this report
to ensure that information required to be disclosed by us in reports that we
file or submit under the Securities Exchange Act of 1934 is recorded, processed,
summarized and reported within the time periods specified in Securities and
Exchange Commission rules and forms. During the most recently completed fiscal
quarter, there has been no significant change in our internal control over
financial reporting that has materially affected, or is reasonably likely to
materially affect, our internal control over financial reporting.

ITEM 2: CHANGES IN SECURITIES AND SMALL BUSINESS ISSUER PURCHASES OF EQUITY
SECURITIES

      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 37,950,000. 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 approximately $1,510,000 has been paid 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
$34,163,000, of which $33,143,000 was deposited into a trust fund and the
remaining proceeds are available to be used to provide for business, legal and
accounting due diligence on prospective business combinations and continuing
general and administrative expenses. Through September 30, 2004, we have used
approximately $ 137,000 of cash for operating expenses and $77,500 to repay
advances made to us by one of our initial stockholders.
