  Notes To Consolidated Financial Statements (Unaudited)


Note A - Basis Of Presentation

The accompanying unaudited condensed consolidated financial statements have been
prepared in accordance with instructions to Form 10-Q and Regulation S-X, and
accordingly, do not include all of the information and footnotes required by
accounting principles generally accepted in the United States for complete
financial statements. In the opinion of management, all adjustments (consisting
of normal accruals) considered necessary for a fair presentation have been
included. The results for the three and six months are not necessarily
indicative of results for the full year. For a more complete discussion of
significant accounting policies and certain other information, you should refer
to the financial statements included in the U.S. Energy Systems Inc.'s (the
"Company") Annual Report Form 10-K for the year ended December 31, 2003, as
amended.

Note B - Net Income (Loss) Per Share

Net Income (Loss) per share has been computed on the basis of the weighted
average number of shares outstanding during the periods. In case of (Loss),
common stock equivalents have not been included in the computation since their
inclusion would be anti-dilutive.

Note C - Income Taxes

The six-month financial statements for the period ended June 30, 2004 reflect an
increase in the deferred tax asset due to the reserve for the investment in SEFL
and the reconciliation of the value of the account offset by gains associated
with the Countryside Power Income Fund (See Note G). In the first six months of
2003 the increase in the deferred tax asset balance reflects increased net
operating loss carry-forwards produced in that period.

Note D - Additional Capital

For the six months ended June 30, 2004, and June 30, 2003, no stock options were
exercised.

Note E - Investments

Scandinavian Energy Finance, Limited / EnergiSystem i Sverige AB. In March 2002,
together with EIC Electricity SA ("EIC"), a Swiss investment company
specializing in energy investments, the Company formed a joint venture,
Scandinavian Energy Finance, Limited ("SEFL") and financed a new Swedish energy
group, EnergiSystem i Sverige AB ("ESS"). SEFL had a 25 year option to acquire
90% of the fully diluted equity of ESS for a nominal sum, which it exercised in
December 2003. As part of the transaction, EnergiSystem acquired seven operating
district energy systems and several late-stage development projects.

SEFL provided approximately $56 million to ESS in the form of financing.
Approximately $45 million of this amount was made in the form of a senior
secured convertible debenture to ESS and approximately $11 million was in the
form of a subordinated loan to EnergiSystem. The senior secured convertible
debenture carries an interest rate of approximately 6% per annum during the
first 2 years and 9% thereafter. The subordinated loan carries an interest rate
of approximately 13%. A Swedish bank provided SEFL with approximately $45
million of long term financing on a non-recourse basis to SEFL's stockholders.
The financing carries a variable interest rate of the Stockholm Inter-Bank
Offered Rate ("STIBOR") plus 30 basis points per annum, capped at 4.7% for the
first 5 years and a rate of STIBOR plus 110 basis points per annum thereafter.
The loan has a 25 year term with no amortization during the first ten years.

We initially invested approximately $5 million in cash and 167,976 of our common
shares, valued at approximately $769,000 in SEFL, and EIC invested its
proportionate share in cash.

On September 30, 2003 ESS sold a 2% interest in SEFL (See Note H) to Borg Energi
AB for $223,000. Due to the issuance of additional common stock to EIC for
additional investments in the fourth quarter of 2003, the Company's ownership
interest in SEFL was reduced to 32% and is accounted for using the equity method
in 2003. The investment in SEFL including equity investments, inter-company
loans and unrepatriated retained earnings amounted to approximately $8.2
million.

                                       8
<PAGE>

As indicated in Note I to the Consolidated Financial Statements for the period
ended March 31, 2004, the Company disclosed pending litigation associated with
the SEFL investment. At the end of the quarter, the Company had reserved its
entire $8.2 million investment in SEFL.

On July 8 2004 in the context of an overall settlement, SEFL sold its loan and
equity investments in ESS to its primary lender, Lantbrukskredit AB ("LBK) for
35.5 million Kronor and a release of SEFL and its shareholders from all
obligations under the financing agreements with LBK. In addition, USEY and ESS
terminated their service agreement. From the 35.5 million Kronor received from
LBK, SEFL paid the Company $1.1m as repayment of an intercompany loan from the
Company to SEFL. Since the amount reserved for SEFL included this intercompany
loan, the $1.1 million will be recognized as a reduction in the reserve amount
during the third quarter of 2004. The $1.1 million was received on July 21,
2004.


Note F - Accounting Changes

The Company's accounting policy pertaining to the financial accounting of the
Illinois rate incentives received by its Illinois-based biogas to energy
projects was changed effective as of April 1, 2001. The change in tax accounting
had no impact on consolidated cash flow.

Following is a summary of the prior period adjustments made to the audited
financial statements:

NOTE G - SALE OF SUBSIDIARIES

Introduction
On April 8, 2004 Countryside Power Income Fund (CPIF), a newly formed Canadian
income fund the Company sponsored, completed its initial public offering of
trust units in Canada pursuant to which it raised approximately $102 million in
net proceeds. All amounts reflected herein are stated in US dollars and the
exchange rate used is the rate effective as of April 8, 2004 of Cdn $1.33 to US
$1.00. In connection with such offering, one or more of US Energy Biogas
Corporation ("USEB") and the Company completed the transactions described below.
The following is a summary of the terms of such transactions and such summary is
qualified in its entirety by reference to the applicable transaction document.


Sale of Canadian District Energy System and USEB Loans
The Company sold to a subsidiary of CPIF, all of the capital stock of USE Canada
Holdings Corp ("USE Canada"), a wholly owned subsidiary that owned two Canadian
based district energy systems. The Company received approximately $15.2 million
including $1.6 millin for the repayment of inter-company debt related to USE
Canada and 13.3 million for the sale of the stock. The sale price was determined
pursuant to arms-length negotiation between the Company and CPIF, with the
involvement of the underwriters of CPIF's initial public offering. The after tax
gain on the sale of the Canadian District Energy System was $4,560,000.

                                       9
<PAGE>

USEB Loan
Countryside Canada Power, Inc. ("Countryside Canada"), a subsidiary of CPIF,
purchased the existing senior debt relating to certain of USEB's projects
("Existing Loans") from the holders thereof. One of such holders, AJG Financial
Services Inc., ("AJG") a subsidiary of Arthur J. Gallagher, Inc., was paid an
aggregate of $6,419,800 (inclusive of principal and accrued interest) for its
portion of the Existing Loans. AJG and its affiliates beneficially own more than
five percent of our common stock

Upon acquisition of the Existing Loans, a subsidiary of the Fund advanced
additional funds of $23,845,ooo ("Additional Advances") to USEB and amended the
Existing Loans to, among other things, cover the Additional Advances and to
modify certain loan covenants that were restrictive to USEB. Among other things,
the Additional Advances were used to fund (i) approximately $9.6 million in
costs related to the acquisition and amendment of the Existing Loans (ii) a debt
service reserve account in the amount of $2 million, (iii) additional desposit
of  and additional deposits of $8,200,000 into the Illinois Reserve account
established to fund reimbursement payments due to the State of Illinois under
the Illinois subsidy and (iv) an improvement reserve of $4 million established
to fund USEB capital projects. Including the Additional Advances, the USEB Loans
have a principal amount of approximately $81 million. The USEB Loans are
denominated in Canadian dollars and the principal amount of such loans is
Cdn$107 million. The loans purchased by CPIF are obligations of USEB, which
obligations are secured by a first ranking lien held by Countryside Canada on
all of USEB's assets (with specified exceptions) and are generally guaranteed by
USEB's subsidiaries. The guaranty obligations of the USEB subsidiaries are
secured by the assets of such subsidiaries (with specified exceptions). The
interest rate on the USEB Loans is 11% per annum, principal and interest is
payable monthly, and the loans mature in 2019, subject to mandatory prepayment
upon the occurrence of specified events and prepayment at the election of the
lender after ten years.

Due the requirement in the amended loan documents that debt service payments be
made to CPIF in Canadian dollars, USEB has entered into a three year hedge
agreement with TD Bank fixing the US dollar to Canadian dollar exchange rate at
US$0.76 per Canadian dollar. The agreement fixes the US Dollar amount USEB pays
CPIF for the monthly principal and interest payments for the 3 year term of the
agreement. Upon the expiration of the hedge agreement in April, 2007, USEB may
be exposed to foreign currency risk at that time. According to the terms of the
loan agreement with CPIF, USEB is required to maintain a foreign currency hedge
agreement for a minimum of 75% of the remaining debt service payments. USEB will
be at risk for fluctuations in the currency exchange rate should the rate vary
from the exchange rate existing in the expiring hedge agreement.


USEB Royalty Interest
Countryside Canada acquired a royalty interest (the "Royalty Interest") in USEB
for $6,000,000, entitling it to receive a quarterly amount (the "Royalty") from
USEB that is determined by reference to, and limited by, USEB's distributable
cash flow (determined in accordance with the royalty agreement). The Royalty
Interest is convertible generally at any time on or after April, 2024 or on or
after the prepayment in full of the USEB Loans, into non-voting common shares of
USEB, representing 49% of the common shares of USEB outstanding at the time of
conversion. Upon conversion of the Royalty Interest, Countryside Canada's right
to receive the Royalty will terminate. The amount of the Royalty payable to
Countryside Canada depends upon whether the Royalty Interest has become
convertible. For each fiscal quarter prior to the quarter in which the Royalty
Interest becomes convertible, the amount of the Royalty payable to Countryside
Canada will be equal to 7% of USEB's distributable cash flow plus 1.8% of USEB's
revenues (determined in accordance with the royalty agreement), but in any
event, the Royalty payment will be subject to the Distribution Cap (described
below). After the Royalty Interest becomes convertible, but remains unconverted,
the Royalty will be equal to 49% of USEB's distributable cash flow, subject to
the Distribution Cap.

The Royalty Interest terminates upon the refinancing of the USEB Loans or the
liquidation or sale of substantially all of the USEB operating assets, in which
case Countryside Canada will be entitled to receive, subject to the Distribution
Cap, $6 million (the "Return Amount") and 49% of the net residual proceeds (as
determined pursuant to the royalty agreement). Notwithstanding the above, no
amount will be payable to Countryside Canada under the Royalty Interest unless,
in the case of the Return Amount, 500% of such amount is distributed
concurrently to the USEB shareholders in respect of their common shares of USEB
and, in all other cases, at least 104.09% of such amount is distributed
concurrently to the USEB shareholders in respect of their common shares of USEB
(the "Distribution Cap").

Development Agreement with Cinergy and US Energy
Pursuant to the Development Agreement by and among Cinergy, US Energy and CPIF
(or the affiliates of the foregoing), during the five year period commencing
April 8, 2004 (subject to an additional five year term unless a party chooses
not to renew), these parties will seek opportunities to acquire or invest in
energy projects that meet CPIF's guidelines on terms acceptable to all parties.
No party is obligated to participate in any project or opportunity. A subsidiary
of CPIF will provide investment analysis and evaluation services on behalf of
these parties in consideration for which the Company will pay annual fees of
$288,100.

                                       10
<PAGE>
If the Company and/or Cinergy divest of an energy project acquired or invested,
pursuant to this development agreement, CPIF (or a subsidiary thereof) will have
a right of first refusal to acquire or invest in such energy project.

Improvement Agreement with USEB and CPIF
USEB has given CPIF a right of first offer to invest in two potential expansion
opportunities relating to the existing Countryside and Morris biogas projects
and two potential greenfield development opportunities currently available to
USEB. The potential expansion of the Morris and Countryside projects would
consist of the replacement of existing electric generation equipment that
management expects will increase capacity and reduce operating costs of each
project. The potential development of the greenfield projects consist of the
construction of energy utilization facilities on existing landfill sites where
gas collection systems have already been constructed.


AJG Genco Transaction
In April 2004, AJG paid Resources Generating Systems, Inc., (RGS) a wholly owned
subsidiary of USEB, for an interest it had previously acquired in Illinois
Electrical Generation Partners, II L.P. (IEGP II). The amount paid was $16
million of which $14 million is payable pursuant to a non-recourse note. The
note bears interest at the rate of 15% per annum, matures in 2024, provides for
scheduled amortization and is secured by AJG's ownership interest in IEPG II.
AJG may defer payments on the note under specified circumstances and in the
event AJG does not make scheduled principal and interest payments because
distributions from IEGP II are insufficient to fund such payments. AJG's
obligations under the note will accrue without triggering an event of default.
During the period ending 30 days after the term of this note, RGS has the right
to acquire from AJG and RGS may be required to buy from AJG, AJG's interests in
Illinois Electrical Generation Partners LP ("IEGP") and IEGP II on specified
terms.

IEGP is the indirect owner of three biogas projects and IEGP II is the indirect
owner of seven biogas projects.

The completion of this transaction resulted in a $16,000,000 non-recurring
pre-tax gain for USEB in the three month period ended June 30, 2004. The USEY
portion of this gain after allowing for Cinergy's minority interest and taxes
amounts to $5,384,000.

NOTE H - BASIS OF PRESENTATION

As indicated in Note E the Company formed a joint venture Scandinavian Energy
Finance, Limited ("SEFL") for the distribution of Biomas-fueled energy to 800
customers in Sweden. The Company originally acquired a 51% interest in the SEFL
venture for approximately $5.8 million and, accordingly, the joint venture's
financial statement had been consolidated with the Company's Financial
Statements. Effective September 30, 2003 the Company sold a 2% interest in the
SEFL venture for $231,000 reducing its interest to 49%. The Company's interest
was further reduced to 32% in the Fourth Quarter of 2003. As a result, the
Company's investment in the SEFL joint venture was accounted for using the
equity method. The deconsolidation of the SEFL Joint Venture had a significant
effect on the Company's consolidated total assets. As indicated in Note E, the
Company has sold its investments in the Swedish energy business to SEFL's senior
lender. The Company has fully reserved its investment in SEFL.


NOTE I - TRANSACTION AND DEBT ISSUANCE COSTS

Transaction and Debt Issuance Costs totaling $12,230,000 consisting of
non-recurring expenses associated with the completion of the transaction with
CPIF were expensed during the period. Included in this amount is $9,886,000
reimbursed to CPIF related to expenses incurred by CPIF in the acquisition of
the Existing Loans from the existing lenders and $2,344,000 of unamortized debt
issuance costs related to the debt acquired by CPIF that remained on USEB books.

Debt issuance costs are amortized on a straight-line basis over the terms of the
financing. For the three months ended June 30, 2004, the amount amortized to
expense was approximately $259,000 and the unamortized balance as of June 30,
2004 was $11.7 million. This amount will be amortized over 15 years, the
remaining term of the debt, with the annual amortization expense equal to
approximately $793,000 on an annual basis.

NOTE J -- DISCONTINUED OPERATIONS

The Company sold its USE Canada operation to the Countryside Fund. The closing
date of the sale was April 8, 2004. The sale of USE Canada resulted in that
entity becoming a discontinued operation in 2003 and was categorized as such on
previous financial statements. Assets and liabilities categorized as
discontinued operations were as follows:

Item 2: Management's Discussion and Analysis of financial condition and RESULTS
OF Operations

Results Of Operations

The revenues and expenses for the three and six months ended June 30, 2004 are
lower than reported in the corresponding periods in the prior year due to a
number of events affecting the Company. These events include: the sale of USE
Canada to the CPIF, the accounting for SEFL under the equity method and the sale
of Geothermal LLC. USE Canada and Geothermal LLC are reflected on the statement
of operations under the caption "Income from Discontinued Operations". See Notes
H and J to the financial statements.


Total revenues decreased $2,751,000 or 38.0 % in the three months ended June 30,
2004 compared with the three months ended June 30, 2003. Total revenues
decreased $4,813,000 or 33.4 % in the first six months of 2004 compared with the
first six months of 2003. These decreases are due principally to certain items
included in the 2003 periods but excluded in the 2004 periods. The table below
indicates the items:

After adjusting total revenues for the non-recurring items, the variations in
the three month and six month periods amount to an increase of $60,000 and
$65,000, respectively, or approximately 1%. The investment in SEFL was reserved
during the first six months of 2004. Non-recurring Revenues related to a
project no longer in operation due to a contract termination and to other
revenues related to operations which were offset by operating expenses as
indicated below.

Operating expenses decreased $1,384,000 or 33.8% in the three months ended 2004
compared with the three months ended June 30, 2003. Operating expenses decreased
$2,101,000 or 29.9% in the first six months of 2004 compared with the first six
months of 2003. The decreases principally reflect items included in the 2003
period but excluded in the 2004 period. The table below indicates the items:

</TABLE>

The large increase in general and administrative expenses in the three month and
six month periods ended June 30, 2004 is due principally to the Incentive
Compensation awarded to employees in connection with the CPIF transaction and
incentive compensation paid to officers per existing employment agreements
which, combined, totaled $3.2 million In addition, $1,348,000 of costs
associated with the CPIF transaction which were previously capitalized were
expensed. CPIF reimbursed the Company $4,839,000 for expenses incurred by the
Company related to the CPIF transaction. This reimbursement has offset
compensation and other general and administrative expenses related to the CPIF
transaction recorded during the period.

Depreciation and amortization expense increased by $243,000 or 28.8% in the
second quarter of 2004 compared with the second quarter of 2003 due principally
to increased amortization of debt issuance costs. During

                                       13

<PAGE>
the first six months of 2004 depreciation and amortization increased by $286,000
or 16.1% compared with the comparable period in 2003. This increase reflects
debt amortization costs. The increase in debt amortization costs in the second
quarter and the six month periods reflect the increase in the amortization of
debt issuance costs associated with the CPIF transaction. The amortization of
debt issuance costs amounts to $793,000 on an annual basis.

The Company reached an overall settlement on its investment in SEFL and reserved
the entire investment of $8.2 million.  See notes E and G to the financial
statements for a further discussion of the two events.

Interest income increased by $502,000 and $521,000 in the three and six months
periods ended June 30, 2004, respectively, compared with the same periods in
2003, reflecting interest on increased cash balances. The increased cash
balances are due to the CPIF transaction.

Interest expense increased by $770,000 or 42.4% in the second quarter of 2004
compared with the second quarter of 2003. Interest expense increased by $695,000
or 15.7 % in the first six months of 2004 compared with the first six months of
2003. In both periods the increase reflects increased interest on long-term debt
due to the CPIF transaction.

Development Costs totaling $12,230,000 consisting of non-recurring expenses
associated with the completion of the CPIF transaction were expensed during the
period. Included in this amount is $9,886,000 reimbursed to CPIF related to
expenses incurred by CPIF in their acquisition of the Existing Loans and
$2,344,000 of unamortized debt issuance costs related to the debt acquired by
CPIF that remained on USEB books.

Income from discontinued operations reflects the after tax net income applicable
to the Canadian District Energy System (USE Canada) which was sold to CPIF in
April 2004 and Geothermal, LLC (Steamboat) which was sold in June 2003.

Gain on sale of subsidiaries reflects the sale of USE Canada to CPIF and the
gain resulting from AJG's payment for its 50% ownership interests in IEGP II
that it had previously acquired. The after-tax gain on the sale of USE Canada
amounted to $5,560,000 and the net gain on AJG's payment for its interest in
IEGP II after allowing for taxes and minority interest amounted to $5,383,000.
For additional information on these items see note G to the consolidated
financial statements.


Liquidity And Capital Resources

At June 30, 2004, cash and cash equivalents totaled approximately $46,763,000 of
which $21,009,000 was unrestricted, compared with $3,210,000 of unrestricted
cash at December 31, 2003. In connection with notes payable by certain USEB
subsidiaries, the lender required these subsidiaries to maintain various
restricted cash accounts, which, at June 30, 2004, amounted to $25,754,000. This
amount also includes approximately $533,000 of funds the Company set aside to
ensure the payment of dividends on certain series of our preferred stock in
accordance with the terms thereof. The increases in total cash and cash
equivalents of $25,850,000 reflect the CPIF transaction.

The large increases in total cash and cash equivalents during the first six
months of 2004 amounting to $25,850,000 reflect the CPIF transaction. During the
first six months of 2004, cash flow was positively impacted by operating
activities, ($4,729,000), by investing activities $15,580,000 and
by financing activities, $14,999,000.

Restricted cash increased by $8,051,000 in the first six months of 2004. The
increase is the result of the funding of various reserve accounts pursuant to
amendments to the Existing Loans in connection with the CPIF transaction. A
total of $8,200,000 was added to the Illinois reserve account, $4,000,000 was
funded into an improvement reserve which can be utilized to expand USEB and
$2,000,000 was deposited into a debt service reserve. These reserve fundings
were offset by the release of previously restricted cash accounts


Our consolidated working capital (including $25,754,000 of restricted cash)
increased to $46,679,000 at June 30, 2004 from $23,850,000 at December 31, 2003
reflecting the increased amount of cash and cash equivalents from the CPIF
transaction.

                                       14

<PAGE>
We continue to evaluate current and forecasted cash flow as a basis to determine
financing operating requirements and capital expenditures. We believe that we
have sufficient cash flow from operations and working capital including
unrestricted cash on hand to satisfy all obligations under outstanding
indebtedness, to finance anticipated capital expenditures and to fund working
capital requirements during the next twelve months.
