ITEM 5.  OTHER EVENTS.

     On September 28, 1994, the registrant (then named O'Brien Environmental
Energy, Inc.) filed a voluntary petition for reorganization under Chapter 11 of
the United States Bankruptcy Code with the United States Bankruptcy Court for
the District of New Jersey (the "Court").  On April 30, 1996, the registrant
emerged from bankruptcy.  The registrant has filed with the Securities and
Exchange Commission under cover of  Form 8-K the monthly reports which were
filed with the Court relating to periods during which the registrant was under
the protection of the bankruptcy laws.  However, because of the pendency of the
bankruptcy proceeding and the related disruptions to the registrant's business
and organization, it was necessary for the registrant to delay the preparation
of audited financial statements for the fiscal year ended June 30, 1995.  Such
financial statements have been prepared and the report thereon of the
registrant's accountants, Price Waterhouse LLP, dated September 16, 1996, has
been issued.  This Report on Form 8-K is filed to report such results.

     Particularly in light of the completion of the bankruptcy proceeding and
the age of the referenced financial statements, the registrant believes that
the following financial statements are not  representative of the current
financial or operational status of the registrant, and that investors should
exercise caution in evaluating such statements.  The registrant expects
to complete the preparation of its financial statements for the year ended June
30, 1996, in October 1996 and to file its Report on Form 10-K for the year ended
June 30, 1996, at the earliest practicable date thereafter.  Investors are
strongly encouraged to review such Report on Form 10-K in its entirety when it
is available and to evaluate the financial statements filed herewith in the
context of the more complete and current information which will be included in
such filing.

                       Report of Independent Accountants


September 16, 1996

To the Stockholders and Board of Directors
of NRG Generating (U.S.) Inc.


In our opinion, the accompanying consolidated balance sheet and the related
consolidated statements of operations, of stockholders' equity and of cash
flows present fairly, in all material respects, the financial position of
O'Brien Environmental Energy, Inc., Debtor-in-Possession, and its subsidiaries
at June 30, 1995, and the results of their operations and their cash flows for
the year in conformity with generally accepted accounting principles. These
financial statements are the responsibility of the Company's management; our
responsibility is to express an opinion on these financial statements based on
our audit. We conducted our audit of these statements in accordance with
generally accepted auditing standards which require that we plan and perform
the audit to obtain reasonable assurance about whether the financial statements
are free of material misstatement. An audit includes examining on a test basis,
evidence supporting the amounts and disclosures in the financial statements,
assessing the accounting principles used and significant estimates made by
management, and evaluating the overall financial statement presentation. We
believe that our audit provides a reasonable basis for the opinion expressed
above. The consolidated financial statements of O'Brien Environmental Energy,
Inc., Debtor-in-Possession, for the years ended June 30, 1994 and 1993 were
audited by other independent accountants whose report dated October 7, 1994
expressed an unqualified opinion on those statements and included an
explanatory paragraph expressing substantial doubt about the Company's ability
to continue as a going concern. That report also disclosed the voluntary
petition filed by the Company for reorganization under Chapter 11 of Federal
Bankruptcy Code in the United States Bankruptcy Court on September 28, 1994.

As discussed in Note 1 to the consolidated financial statements, on April 30,
1996, O'Brien Environmental Energy, Inc.  was reorganized pursuant to a plan of
reorganization submitted by NRG Energy, Inc., the O'Brien Official Committee of
Equity Security Holders and Wexford Management Corp., and approved by the
Bankruptcy Court for the District of New Jersey on January 18, 1996. As part of
the reorganization, NRG Energy, Inc. acquired an approximate 42% equity
interest in the reorganized company, renamed NRG Generating (U.S.) Inc.

  1.  BUSINESS - LIQUIDITY AND CAPITAL RESOURCES

      O'Brien Environmental Energy, Inc. and its subsidiaries (the "Company")
      develop, own and operate biogas projects and develop and own cogeneration
      and waste-heat recovery projects which produce electricity and thermal
      energy for sale to industrial and commercial users and public utilities.
      In addition, the Company sells and rents power generation, cogeneration
      and standby/peak shaving equipment and services.

      On April 30, 1996, O'Brien Environmental Energy, Inc., the parent
      company, emerged from bankruptcy. The plan of reorganization, approved on
      January 18, 1996 by the U.S. Bankruptcy Court for the District of New
      Jersey (the "Court"), awarded NRG Energy, Inc. ("NRG") the rights to
      acquire a 41.86% equity interest in the Company and generally provided
      for full and immediate payment of all undisputed prepetition liabilities
      and included a provision for post-petition interest. The Company was
      renamed on the April 30, 1996 closing date to NRG Generating (U.S.) Inc.
      ("NRGG").

      O'Brien Environmental Energy, Inc., the parent company, filed a voluntary
      petition for reorganization under Chapter 11 of the United States
      Bankruptcy Code with the Court on September 28, 1994 to pursue financial
      restructuring efforts under the protection afforded by the U.S.
      bankruptcy laws. The decision to seek Chapter 11 relief was based on the
      conclusion that action had to be taken to preserve its relationships and
      maintain the operational strength and assets of the Company and to
      restructure its debt and utilize its assets in a manner consistent with
      the interests of all creditors and shareholders rather than liquidate to
      satisfy the demands of a particular group of creditors. The Company
      continued its normal operations as Debtor-in-Possession during the
      bankruptcy period but could not engage in transactions outside the
      ordinary course of business without approval, after notice and hearing,
      of the Court.

      Under the Chapter 11 bankruptcy proceedings, all parent company
      ("Debtor") liabilities and claims which existed on the September 28, 1994
      filing date were stayed. The Company segregated and reclassified these
      Debtor liabilities on its balance sheet to "Prepetition Liabilities."
      Subsequently, the Debtor received approval from the Bankruptcy Court to
      make payments on certain prepetition obligations including employee wages
      and expense reports and was also directed to make periodic adequate
      protection payments on specific secured debt obligations.

      Management concluded that the maximum return to creditors and
      shareholders could only be accomplished through the sale of an equity
      interest in the Company or of substantially all of its assets to a third
      party and focused its reorganization efforts on the implementation of a
      sale process. After extensive solicitation efforts, two separate third
      party plans of reorganization

      were submitted to the Bankruptcy Court. On November 17, 1995, the Company
      distributed a Master Disclosure Statement urging that creditors and equity
      security holders vote to accept both plans of reorganization to further
      enhance recovery. The competitive bidding process extended to the
      confirmation hearings.

      On January 18, 1996, the Bankruptcy Court confirmed the plan of
      reorganization (the "Plan") submitted by NRG, the O'Brien Official
      Committee of Equity Security Holders and Wexford Management Corp
      ("Wexford") in which NRG would acquire an approximate 42% equity interest
      in the reorganized company.

      On April 30, 1996, NRG funded approximately $107,418 in accordance with
      the Plan and acquired a 41.86% equity interest in the Company. The funds
      were disbursed according to the Plan's terms which generally provided for
      full payment (or cure/reinstatement) of all undisputed prepetition
      liabilities including the payment of post-petition interest on most
      prepetition obligations. The funding also included a $7,500 escrow fund
      for a prorata direct distribution by NRG to shareholders. Additionally,
      disbursements were made to certain creditors of subsidiary companies
      whose obligations were not included in prepetition liabilities and for
      professional fees incurred during the bankruptcy proceedings. Certain
      other bankruptcy claims filed with the Court remain in dispute. An escrow
      fund has been established to fully reserve for these disputed claims. Any
      remaining funds resulting from the Court disallowing any disputed claims
      will be disbursed prorata to all allowed non-reinstated creditor
      claimholders as additional post-petition interest (see Note 32).

  2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

      Basis of presentation
      The consolidated financial statements include the accounts of the Company
      and all significant subsidiaries which are more than 50 percent owned and
      controlled. Intercompany transactions and unrealized intercompany profits
      and losses on transactions with equity method investees have been
      eliminated in consolidation. Foreign subsidiaries with fiscal years
      ending on March 31 are included in the consolidated financial statements.
      If events occurred between March 31 and June 30 which materially affect
      the consolidated financial position or results of operations, they would
      be reflected in the consolidated financial statements. Investments in
      less than majority-owned entities are recorded at cost plus equity in
      their undistributed earnings or losses since acquisition.

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

      Prepetition liabilities
      Outstanding and unpaid liabilities of the parent company which existed as
      of the filing for bankruptcy on September 28, 1994 subject to the Court
      proceedings are presented separately on the June 30, 1995 balance sheet
      as prepetition liabilities at amounts expected to be approved by the
      court as allowed claims.

      Reorganization costs
      Expenses incurred after filing bankruptcy incurred in the Company's
      reorganization and restructuring efforts have been presented separately
      in the statement of operations as reorganization costs.

      Revenue recognition
      Energy revenues from cogeneration and biogas projects are recognized as
      billed over the term of the contract.  Profits and losses from sales and
      rental of power generation equipment, including sales to projects in
      which the Company retains less than a 100% interest are recognized as the
      equipment is sold or over the term of the rental.  Development fee
      revenue is recognized on a cost recovery basis as cash is received
      (without future lending provisions) or as equity interest in the
      partnership increases, whereby revenues are recognized subsequent to the
      recovery of all project development costs.

      Inventories
      Inventories, consisting principally of power generation equipment and
      related parts held for sale are valued at the lower of cost (determined
      primarily by the specific identification method) or market.

      Property, plant and equipment
      Property, plant and equipment is stated at the lower of cost or appraised
      fair market value and depreciated using the straight-line method over the
      estimated useful lives of the assets which range from five to thirty
      years.  Amortization on equipment acquired under capital leases is
      recognized on a straight line basis over the shorter of the estimated
      asset life or lease term. Depreciation on equipment held for future
      projects is not provided until the equipment is placed in service. For
      income tax purposes, the Company uses a combination of accelerated and
      straight-line depreciation methods.

      Cost of maintenance and repairs is charged to expense as incurred.
      Betterments and improvements are capitalized.  Upon retirement or other
      disposition of items of plant and equipment, cost of items and related
      accumulated depreciation are removed from the accounts and any gain or
      loss is included in the results of operations.

      Equipment held for sale
      Equipment held for sale consists of power generation equipment not
      currently being used in an operating project and is valued at the lower
      of cost or estimated net realizable value.

      Project development costs
      Project development costs consist of fees, licenses and permits, site
      testing, bids and other charges, including salary and interest charges
      incurred by the Company in developing projects. For wholly-owned
      projects, these costs are transferred to property, plant and equipment
      upon commencement of construction and depreciated over the contract term
      when operations begin. For projects structured as partnerships, these
      costs may be recovered through development cost reimbursements from the
      partnership or third parties or may be transferred to an investment in
      the partnership. It is the Company's policy to expense these costs in any
      period in which management determines the costs to be unrecoverable.

      Deferred financing costs
      Financing costs are deferred and amortized on a straight-line basis over
      the term of the related financing.

      Recourse long-term debt and nonrecourse project financing
      Recourse long-term debt consists of collateralized long-term debt for
      which repayment is a general obligation of the Company exclusive of any
      debt subject to the bankruptcy proceedings. Nonrecourse project financing
      consists of long-term debt for which repayment obligations are limited to
      specific project subsidiaries.

      Income taxes
      The provision for income taxes has been calculated using the asset and
      liability approach of accounting for income taxes. Under this approach,
      deferred taxes represent the future tax consequences expected to occur
      when the reported amounts of assets and liabilities are recovered or
      paid. The provision for income taxes represents income taxes payable or
      paid for the current year and the change in deferred taxes during the
      year. Deferred taxes result from differences between the tax and
      financial bases of the Company's assets and liabilities and are adjusted
      for any changes in the tax rates and laws. Valuation allowances are
      recorded when it is more likely than not that a tax benefit will not be
      realized.

      Gas swap agreements
      The Company enters into gas swap agreements from time to time to reduce
      the impact of changes in gas prices on its operating income. The
      differentials to be paid or received under such agreements are accrued
      and are recorded as increments or decrements to gas expense.

      Interest rate swap agreement
      The Company has entered into an interest rate swap agreement to reduce
      the impact of changes in interest rates on certain of its variable rate
      nonrecourse debt. The differentials paid or received under such
      agreements are accrued and are recorded as increments or decrements to
      interest and debt expense.

      Cost in excess of net assets acquired
      Excess of cost of investment in subsidiaries over net assets at the date
      of acquisition is being amortized by charges to operations on a
      straight-line basis over twenty-five years. It is the Company's policy to
      expense excess cost of investment in any period in which management
      determines these costs to be unrecoverable.

      Net income (loss) per share
      Net income (loss) per share is calculated by dividing net income (loss)
      by the weighted average shares of common stock and common stock
      equivalents outstanding. Fully diluted net income (loss) per share is not
      presented because conversion of the convertible senior subordinated
      debentures and other common stock equivalents would be antidilutive.

      Foreign currency accounting
      The financial statements of foreign subsidiaries have been translated in
      accordance with Statement of Financial Accounting Standards No. 52,
      whereby assets and liabilities are translated at year-end rates of
      exchange and statements of operations are translated at the average rates
      of exchange for the year. Currency translation adjustments are
      accumulated in the other component of stockholders' equity until the
      entity is substantially sold or liquidated.

      Transaction gains and losses associated with foreign activities are
      reflected in operations.

      Cash and cash equivalents
      For purposes of the consolidated statements of cash flows, the Company
      considers all highly liquid investments with maturities of three months
      or less at the time of purchase to be cash equivalents.

      Concentration of credit risk
      The Company primarily sells electricity and steam to public utilities and
      corporations on the east and west coasts of the United States under
      long-term agreements. Also, the Company services, sells and rents
      equipment to various entities worldwide. The Company performs on-going
      credit evaluations of its customers and generally does not require
      collateral. The Company maintains reserves for potential credit losses
      and such losses have been within management's expectations.

      The Company invests its excess cash in deposits with financial
      institutions. Those securities typically mature within ninety days and,
      therefore, bear minimal risk. The Company has not experienced any losses
      on these deposits.

  3.  CASH AND RESTRICTED CASH

      Due to restrictions in the Newark and Parlin project financing
      agreements, $3,520 and $2,346 of cash and cash equivalents at June 30,
      1995 and 1994, respectively, is generally available for use only by those
      projects.

      Additionally, the Company has classified certain cash and cash
      equivalents that are not fully available for use in its operations as
      restricted. Restricted cash and cash equivalents relate primarily to debt
      service reserve accounts for O'Brien (Newark) Cogeneration, Inc. and
      O'Brien (Parlin) Cogeneration, Inc. (see Note 17) and compensating
      balances maintained by the Company at financial institutions in
      connection with lines of credit extended to its United Kingdom
      subsidiaries (see Note 13).

      Restricted cash and cash equivalents consist of the following:

      Depreciation expense was $8,892, $9,717 and $9,643 in 1995, 1994 and
      1993, respectively.

      The Company recorded a charge of $15,985 in the fiscal 1995 fourth
      quarter to reduce the carrying amount of property, plant and equipment to
      a lower fair market appraised value. Additionally, the Company
      reclassified the reduced appraised value of certain equipment held for
      future projects to equipment held for sale based upon the anticipated
      implementation of the NRG plan of reorganization.

      Equipment related to energy revenues includes the property and equipment
      of the Newark and Parlin cogeneration plants and the biogas projects.

      The Newark project consists of a 52 megawatt cogeneration power plant in
      Newark, New Jersey which commenced operations in November 1990 and is
      supplying electricity and steam pursuant to 25-year supply contracts. The
      facility has been financed utilizing nonrecourse project financing (see
      Notes 17 and 32).

      The Parlin project consists of a 122 megawatt cogeneration power plant in
      Parlin, New Jersey which commenced operations on June 26, 1991 and is
      supplying 101 megawatts of electricity pursuant to a 20-year electric
      supply contract and steam pursuant to a 30-year supply contract. The
      facility has been financed utilizing nonrecourse project financing (see

 5.   EQUIPMENT HELD FOR SALE

      As part of the Company's debt restructuring program and its efforts to
      improve both short-term and long-term liquidity, it has actively begun
      seeking buyers for specific energy equipment not currently being used in
      an operating project nor critical to the completion of any projects in
      development. These assets, consisting mainly of gas and steam turbines,
      are being held for sale in order to raise cash.

      The value of these assets sold in a secondary market is less than if they
      were incorporated into an internally developed operating project.
      Accordingly, the Company recorded a noncash charge in the fourth quarter
      of the fiscal 1994 period in the amount of $6,250 to adjust the carrying
      value of these assets to an estimated resale value of $8,458 based upon
      appraisals made by the Company.

      In the fourth quarter of the fiscal year ended June 30, 1995, the Company
      recorded an additional charge of $5,655 based upon a recent independent
      appraisal report to further reduce the carrying value to reflect the
      Company's intent to accelerate the disposal of this equipment.

 7.   COALBED METHANE GAS PROPERTIES NOTE

      In August 1993, the Company entered into an arrangement with an unrelated
      third party joint venture to sell substantially all proved and unproved
      coalbed methane gas properties for $6,500. The Company received $2,000 in
      cash and a production payment note receivable of $4,500. In addition, the
      Company agreed to contribute up to $800 to complete non-producing wells
      into commercial wells which was included in other current liabilities at
      June 30, 1994. The Company discounted the note in fiscal 1994 to an
      estimated net realizable value in consideration of the Company's plans to
      monetize the note and accelerate cash flow. Fiscal 1994 development fees
      and other includes $5,121 of revenues recognized in connection with this
      sale.

      In May 1994, the joint venture filed a complaint with the American
      Arbitration Association. The Company subsequently counterclaimed. On
      March 31, 1995, a settlement agreement was executed with the joint
      venture to resolve all disputes in which the Company accepted
      responsibility for $1,166 in cost reimbursement toward completion on
      non-producing wells with interest at prime plus 5%. The joint venture
      accepted an assignment of any and all payments due the Company on the
      note receivable in satisfaction of the obligation until the sums withheld
      satisfy the obligation plus all accrued interest. Until the obligation
      plus all accrued interest is satisfied in full, the Company has no rights
      to the net revenues, as defined, nor can the note receivable be sold,
      pledged or assigned to any other party. The joint venture is not entitled
      to look to the Company for the payment of any cost obligations. Only
      after recoupment of the chargeback obligation, will payment on the note
      receivable be paid from a percentage of net revenues, as defined, from
      the coalbed methane properties until the earlier of (1) the note is paid
      in full or (2) 10 years. At June 30, 1995, the Company has reduced the
      carrying value of the note by the cost obligation and fully reserved the
      balance (see Note 6).

 9.   NOTES RECEIVABLE FROM FORMER OFFICER

      At June 30, 1995, the Company had notes receivable totaling $238 from a
      former officer of the Company. The notes are unsecured and bear interest
      at 8.25% per annum. At June 30, 1995, the Company established a reserve
      for the notes and accrued interest to reflect a court approved
      stipulation agreement between the Official Committee of Unsecured
      Creditors ("the Committee") and the former officer whereby, in
      consideration of the notes, the former officer agreed to withdraw his
      claim against the Company and assist the Committee with its prosecution

      In March 1996, Trigen (Schuylkill) Cogeneration, an unrelated party, was
      admitted to the partnership. O'Brien Schuylkill and Adwin each received a
      $1,000 admittance fee. Net operating profits and losses will be allocated
      to the partners, generally equally, based upon the terms and provisions
      as stated in the partnership agreement. Also in March 1996, the
      partnership entered into a credit agreement with Chase Manhattan Bank
      N.A. to finance the construction and equipment for the facility. Pursuant
      to the credit agreement, the three partners will each contribute $10,000
      of additional capital to the partnership.  Additionally, the stock of
      O'Brien Schuylkill was pledged as collateral for the loan.

      NRG and O'Brien Schuylkill entered into a $10,000 credit agreement in
      March 1996, guaranteed by the Company, to provide funding for this
      commitment when required (see Note 32).

      Artesia
      The Artesia project consists of a 32 megawatt cogeneration facility in
      Artesia, California which commenced operations in 1990 and is supplying
      electricity and steam pursuant to 30-year supply contracts. The project
      is owned and operated by O'Brien California Cogen Limited, a limited
      partnership. O'Brien Cogeneration, Inc. II ("Cogen II"), a wholly-owned
      subsidiary of the Company, is the managing general partner. In addition
      to its share of the limited partnership's operations, the Company
      receives annual management fees of approximately $138 and participates in
      a fuel supply partnership. On April 30, 1996, Cogen II was sold to NRG
      under the terms of the plan of reorganization (see Note 32).

      PoweRent Limited
      PoweRent Limited, an entity in which a subsidiary of the Company owns a
      50% interest, is a United Kingdom company that sells and rents power
      generation equipment. The remaining 50% of PoweRent is owned by an
      officer of a wholly- owned United Kingdom subsidiary.

      Intrag, Joint Venture
      Intrag, Joint Venture was formed for the purpose of developing power
      generation projects and for the manufacture, sale and/or rental of power
      generation equipment in Pakistan. The Company relinquished its equity
      interest in the Joint Venture opting instead to participate as an
      equipment vendor to the project. Under Pakistani law, a Company cannot
      simultaneously be a vendor and own an equity interest in the same joint
      venture. Accordingly, the Company expensed its investment in equity
      affiliate as unrecoverable.

      The Company's investment in equity affiliates has been accounted for
      using the equity method.

14.   Prepetition Liabilities

      All liabilities at June 30, 1995 subject to the bankruptcy proceedings
      have been classified on the balance sheet as prepetition liabilities
      stated at amounts expected to be approved by the court as allowed claims
      and consist of the following:

<TABLE>
      <S>                                                            <C>
      Subordinated debentures (see Note 16)                          $   49,174
      Recourse debt (see Note 15)                                        30,368
      Prepetition accrued interest                                        5,634
      Accounts payable and accrued expenses                               2,567
                                                                     ----------
                                                                     $   87,743
                                                                     ==========
</TABLE>

      During the bankruptcy proceedings, the Company received approval from the
      Court to make payments on certain prepetition liabilities including
      employee wages and expense reports incurred prior to the filing. The
      Court also ordered the Company to make periodic adequate protection
      payments on certain secured debt obligations and allowed the continuation
      of payments due on insurance premiums which had been financed prior to
      September 28, 1994. In addition, the Company has accrued $6,194 for
      post-petition interest through June 30, 1995 on prepetition liabilities
      which is included on the balance sheet as a component of accrued interest
      expense. The NRG plan of reorganization provides for the payment of
      post-petition interest on primarily all prepetition obligations (see Note
      32).

15.   Recourse Long-Term Debt

      Upon the parent company filing a petition for bankruptcy, all debt
      subject to compromise was reclassed to prepetition liabilities (see Note
      14). Recourse long-term debt at June 30, 1995 consists of post-petition
      financing and of all subsidiary long-term recourse debt which is not part
      of the bankruptcy proceedings.

      (a)  The Company reclassified a $5,000 current liability to long-term
           debt at June 30, 1994. The $5,000 repurchase option for the
           Philadelphia Water Department project reacquired on August 5, 1994
           was funded by long-term financing from an unrelated third party in
           August 1994. The refinancing was reclassified to prepetition
           liabilities on September 28, 1994 and is collateralized by the
           common stock of the reacquired subsidiary.

      (b)  As a result of defaults under certain of a subsidiary company's loan
           agreements, the Company reclassified $4,374 out of a long-term
           classification for a total of $8,751 of its recourse debt as a
           current liability.  Of this amount, approximately $2,383 was
           triggered by non-payment and the remainder, $1,991, remains
           reclassified because of the Chapter 11 bankruptcy filing on
           September 28, 1994.

      and 1993, respectively. Of these amounts $403 and $1,873 were capitalized
      in 1994 and 1993, respectively. No amounts were capitalized in 1995.

      On August 22, 1994, the trustees for each of the 1987 Debentures, 1990
      Debentures and 1991 Debentures (collectively, the "Debentures") delivered
      acceleration notices to the Company demanding immediate payment of the
      total principal of $49,174 and past due interest in the amount of $5,231
      as of September 20, 1994 based on the following factors:

      -  The Board of Directors elected not to make the March 15, 1994 or the
         September 15, 1994 semi-annual required interest payments on the
         Debentures which total $5,036. Each semi-annual required interest
         payment consists of $442, $632 and $1,444 for the 1987 Debentures,
         1990 Debentures and 1991 Debentures, respectively.

      -  The Company was in default under the 1987 indenture's funded
         indebtedness covenant (as defined in the 1987 indenture). Such
         covenant prohibited the Company from incurring or creating any funded
         indebtedness, if, after giving effect to such incurrence or creation,
         the total outstanding funded indebtedness of the Company on a
         consolidated basis would exceed 75% of the sum of consolidated
         stockholders' equity and funded indebtedness.

      Additionally, the Company was in default under the 1987 indenture, 1990
      indenture and 1991 indenture due to defaults on other indebtedness which
      results in the acceleration of the maturity of at least an aggregate of
      $1,000, $2,000 and $2,000, respectively, of other indebtedness which is
      not cured within 60 days, 90 days and 90 days, respectively, after notice
      to the Company.

      As a result of the losses experienced by the Company, a covenant in the
      1990 indenture and 1991 indenture requiring the Company to purchase 7.5%
      of the outstanding 1990 Debentures and 1991 Debentures if the Company's
      consolidated stockholders' equity is less than $10,000 at the end of each
      of any two consecutive fiscal quarters was triggered. Additionally, a
      covenant in the 1987 indenture requires the Company to purchase 7.5% of
      the outstanding 1987 Debentures if the Company's consolidated
      stockholders' equity is less than $7,500 at the end of each of any two
      consecutive fiscal quarters. The Company was unable to satisfy these
      default obligations.

      In May 1994, the Company filed a Registration Statement on Form S-4 (the
      "Registration Statement") with the Securities and Exchange Commission
      relating to a proposed exchange offering of cumulative senior preferred
      stock and Class A common shares and warrants for each $1 principal amount
      of debentures outstanding and a solicitation of consent to certain
      proposed amendments to the Indentures as well as the waiver of all
      defaults under the debentures. In June 1994, an amendment to the
      Registration Statement was filed. Subsequent to such amendment, the
      Company began discussions with an ad hoc committee (the "Ad Hoc
      Committee") representing the holders of the debentures and entered into a
      standstill agreement with the Ad Hoc Committee pursuant to which the
      Company agreed, among other things, to assist the Ad Hoc Committee in its
      due diligence efforts. The failure to reach an agreement with the Ad Hoc
      Committee was one of the factors upon which the Company's decision to
      file for protection under the Bankruptcy Code was based (see Note 1).

      The Debentures became subject to compromise on the September 28, 1994
      bankruptcy filing date. The Court subsequently ruled that the total
      principal and accrued interest outstanding on September 28, 1994 in the
      amount of $49,174 and $5,231, respectively, were allowed claims. On April
      30, 1996, the debentures were fully funded and paid with post-petition
      interest in accordance with the NRG plan of reorganization (see Note 32).

      The Form S-4 registration statement was declared abandoned by the
      Securities and Exchange Commission on March 1, 1996.

      Nonrecourse project financing consists of the following:

                                                                          $   -       $   60,310
                                                                          =========   ==========
</TABLE>

      The nonrecourse project financing agreements contain various covenants,
      the most restrictive of which are the maintenance of positive working
      capital, limitation on the payment of dividends or other distributions to
      the Company and a restriction on additional borrowings by the project
      subsidiaries.

      At June 30, 1995 and 1994, both the Newark and Parlin projects were in
      default of the covenant which requires the maintenance of positive
      working capital. At June 30, 1995, because of the ongoing bankruptcy
      proceedings of the parent, neither the Newark or Parlin subsidiaries
      sought waivers from the lenders and accordingly, classified the entire
      amounts outstanding as short-term debt due to a default of positive
      working capital.

      On September 26, 1994, the project lenders agreed to waive this covenant
      at June 30, 1994 through July 1, 1995 for the Parlin project only. The
      lenders were not willing to provide a similar waiver for the Newark
      project at June 30, 1994 and, as a result, $25,010 of Newark's
      nonrecourse debt was reclassified from long-term to short-term debt in
      fiscal 1994.

      (a)  The Newark project financing is an obligation of O'Brien (Newark)
           Cogeneration, Inc. ("Newark"), a wholly- owned subsidiary of the
           Company. The project financing was converted from a nonrecourse
           construction loan to a nonrecourse 12-year term loan in October
           1990. On June 6, 1995, Newark executed a Settlement and
           Restructuring

           Agreement (the "agreement") which significantly changed the terms of
           the loan. Among other things, the agreement allowed monthly
           predetermined cash distributions to the parent,  obligated monthly
           rather than semi-annual debt payments to the lender, accelerated the
           maturity date to January 1997 and provided for escalating interest
           rate margin increases initially at 1.25% effective January 1, 1995
           increasing to a maximum 2.75% per annum throughout the remaining
           term of the loan. The effective interest rate on the loan at June
           30, 1995 was 7.37%. Additionally, the agreement designated all cash
           as restricted and obligated that Newark's monthly "excess cash," as
           defined, be used to pay off any outstanding bank fees and,
           thereafter, applied as additional principal payments on the term
           loan. Previously, the term loan provided for a variable interest
           rate tied to either LIBOR or the prime rate. During 1995, 1994 and
           1993, $2,065, $1,693 and $1,759, respectively, of interest costs
           were incurred pursuant to the project financing. The sole collateral
           for the term loan is the common stock of Newark, which has net
           assets of approximately $40,574 excluding the nonrecourse financing
           at June 30, 1995.

           On May 17, 1996, the Company entered into a Credit Agreement with a
           new lender (the "New Agreement"). On May 23, 1996, the Company
           borrowed $60,000 in the form of a six-month term loan pursuant to
           the New Agreement and used the proceeds, among other things, to
           refinance the Newark nonrecourse project finance debt ($19,001
           outstanding on that date). On July 11, 1996, the six-month term loan
           was incorporated into a $155,000 term loan which is a joint and
           several obligation of both the Newark and Parlin projects (see Note
           32).

      (b)  The Parlin financing is an obligation of O'Brien (Parlin)
           Cogeneration, Inc. ("Parlin"), a wholly-owned subsidiary of the
           Company. The project financing was converted from a nonrecourse
           construction loan to a nonrecourse 12-year term loan in December
           1990. Through the use of an interest rate swap agreement, $43,389 of
           the term loan has a fixed interest rate of approximately 11% per
           annum for a period of 10 years. The Company is exposed to credit
           loss in the event of nonperformance by the other party to the swap,
           however, the Company does not anticipate nonperformance. The balance
           of the loan has a variable interest rate tied to LIBOR or the prime
           rate unless the Company chooses to fix the interest rate at the
           prevailing long-term market rates. At June 30, 1995, approximately
           $16,921 of this loan had a floating rate of 7.37%. During 1995, 1994
           and 1993, $6,470, $6,633 and $7,166 of interest costs were incurred
           pursuant to the term loan which includes $2,050, $3,253 and $3,544
           for 1995, 1994 and 1993, respectively, of costs associated with the
           interest rate swap agreement. The sole collateral for the term loan
           is the common stock of Parlin which has net assets of approximately
           $65,610 excluding the nonrecourse financing at June 30, 1995.

           On June 28, 1996, NRG purchased the outstanding Parlin nonrecourse
           project debt from the lender ($52,838 outstanding on that date) and
           paid a $3,100 brokerage fee to terminate the interest rate swap
           agreement. On July 11, 1996, the Company borrowed $95,000 under the
           terms of the New Agreement and used the proceeds, among other
           things, to repay NRG for the funds advanced on June 28, 1996. The
           New Agreement provides for a $155,000 term loan which is a joint and
           several obligation of both the Newark and Parlin projects (see Note
           32).

18.   STOCKHOLDERS' EQUITY

      Preferred stock
      The Board of Directors of the Company is authorized to issue shares of
      preferred stock in one or more series and to determine the rights and
      preferences of each series (see Note 32).

      Common stock
      Except for voting and conversion privileges, shares of Class A and Class
      B common stock are identical. Class A stockholders are entitled to one
      vote per share while Class B stockholders are entitled to ten votes per
      share.  Class B common stock is convertible into Class A common stock on
      the basis of one share of Class A common stock for each share of Class B
      common stock (see Note 32).

      All outstanding shares of Class B common stock were owned by III
      Enterprises, Inc., a company wholly-owned by the former Chairman and
      Chief Executive Officer of the Company, which had the controlling voting
      interest in the Company. In October 1993, III Enterprises, Inc. filed for
      bankruptcy protection under Chapter 11 of the Federal Bankruptcy Code.
      The Class B shares were pledged to one or more principal lenders of III
      Enterprises, Inc. On July 10, 1995, under a foreclosure sale, Wexford
      acquired 1,360,000 shares of the pledged Class B common stock from a III
      Enterprises, Inc. lender. In addition, Wexford was granted a proxy to
      vote a further 1,360,000 shares of the pledged stock held by the lender.
      Wexford also acquired 100,000 and 380,000 shares of Class B common stock,
      respectively, from two separate III Enterprises, Inc. lenders. Prior to
      these acquisitions, Wexford had owned 178,071 shares of Class A common
      stock.

      As a result of its acquisition of the pledged Class B common stock,
      Wexford obtained voting control of the Company and accordingly replaced
      all Class B directors at an August 8, 1995 meeting of the Board of
      Directors. The ability of Wexford and/or the Board of Directors to direct
      the actions of the Company was, however, limited by July 27, 1995 and
      August 30, 1995 orders of the Court which generally prohibited the board
      from terminating or directing management authority of the Court appointed
      Crisis Manager who was acting as Chief Administrative Officer of the
      Company.

      On April 30, 1996, in accordance with the NRG plan of reorganization, all
      Class A and Class B common shares of the Company were canceled and
      exchangeable for a new single class of common shares of NRGG, the
      reorganized Company.  Under the plan, NRGG issued 6,474,814 common shares
      of which 2,710,357 (41.86%) is owned by NRG and the remaining 3,764,457
      shares (58.14%) became issuable to the existing shareholders of the
      Company. In addition, holders of the Company's Class A and Class B shares
      became entitled to receive an aggregate $7,500 (approximately $.44 cents
      per old share) from NRG. The cash distribution is payable to shareholders
      when the old common shares are submitted to the transfer agent for
      exchange (see Note 32).

      Minority interest
      On August 5, 1994, the Company reacquired an 83% interest in the
      Philadelphia Water Department Project by exercising its repurchase option
      for the common stock of O'Brien (Philadelphia) Cogeneration, Inc. ("OPC")
      from an unrelated private investor for $5,000. The remaining 17% interest
      was retained by the private investor represented by 100 shares of OPC
      Series A preferred Stock, $.01 par value and redeemable by the Company at
      its option for a price, as defined, equal to 17% of the present value of
      the projected income stream of the project as set forth in the repurchase
      agreement. The private investor can also obligate the Company to
      repurchase all, but not less than all, outstanding OPC Preferred Stock at
      60% of the Company's redemption price. The Company's redemption price at
      June 30, 1995 was approximately $2,084.

      The OPC preferred stock also obligates a quarterly distribution of 17% of
      the net earnings of OPC, as defined, payable within 50 days of the end of
      each respective quarter. These distributions amounted to $209 through
      June 30, 1995 and are reported as interest expense in the consolidated
      statement of operations (see Note 31).

      Other
      The other component of stockholders' equity includes a foreign currency
      translation adjustment of ($562), ($587) and ($551) at June 30, 1995,
      1994 and 1993, respectively, and treasury stock of $64 at June 30, 1995,
      1994 and 1993. Treasury stock is recorded at cost and consists of 90,200
      shares of Class A common stock and 165,000 shares of Class B common
      stock, including 75,000 shares of Class A common stock and 165,000 shares
      of Class B

      common stock held by O'Brien Energy Services Company ("OES"), a
      wholly-owned subsidiary, at the date of its acquisition by the Company.

19.   STOCK OPTIONS

      The Company had several stock option plans for the granting of qualified
      and/or nonqualified options on Class A common stock to officers,
      directors and key employees. Under the terms of the NRG plan of
      reorganization, these stock options were terminated on April 30, 1996. No
      options were exercised in fiscal 1995 or 1994 nor were any options
      exercised through the closing date.

20.   BUSINESS INTERRUPTION INSURANCE CLAIMS

      During 1995, 1994 and 1993, energy revenues include $1,035, $1,706 and
      $6,247 received under net business interruption insurance claims
      associated with the Newark and Parlin cogeneration plants.

21.   DEVELOPMENT FEES AND OTHER

      In September 1994, the Company sold its rights to develop a 14 megawatt
      standby electric facility project for $1,762.

      In June 1994, the Company sold its rights to develop a standby/peak
      shaving project for a $5,000 cash payment which is included in
      development fees and other income. The costs associated with the
      development rights were insignificant.

      In August 1993, the Company sold its contractual rights to develop
      certain coalbed methane reserves. The selling price consisted of a $2,000
      cash payment and a production note of $4,500. The Company discounted the
      note in fiscal 1994 by $1,379 to reflect a lower estimated net realizable
      value in consideration of the Company's plans to monetize the note and
      accelerate cash flow. The previously capitalized costs and remaining
      drilling obligation amounted to approximately $5,100 resulting in no gain
      on the transaction. A March 1995 settlement agreement resolved a dispute
      between the Company and the purchaser regarding a chargeback obligation.
      The Company further discounted the note for the chargeback obligation and
      fully reserved the balance (see Notes 6 and 7).

      In December 1992, the Company and a utility entered into an agreement
      pursuant to which the electric contract previously entered into was
      terminated for $4,000 from the utility, payable in five annual
      installments of $800 without interest. The payments are collateralized by
      a standby letter of credit. The net present value of the $4,000 was
      determined to be $3,462, assuming an interest rate of 5.95% and is
      reflected as development fees and other in the accompanying consolidated
      statements of operations. The associated project development costs
      amounted to $2,386 which resulted in a net gain of $1,076.

      In December 1992, the Company sold a biogas project located in the United
      Kingdom for $821, of which $331 was paid pursuant to a promissory note
      with an interest rate of 8% and is reflected as development and other
      fees in the accompanying consolidated statements of operations. The
      associated project development costs amounted to $265, which reflects a
      $66 discount for early payment offered by the Company.

      In September 1992, the Company sold a 50% interest in a biogas project
      pursuant to a stock purchase agreement. The remaining 50% interest was
      sold on June 30, 1993. The aggregate sale price was $625 of which $555
      was paid pursuant to a promissory note with an interest rate of 8%. The
      costs associated with the sale amounted to $267 which resulted in a net
      gain of $358.

      In June 1992, the Company sold the power purchase, landfill gas and other
      agreements associated with two biogas projects that were operated by the
      Company to two unrelated limited partnerships for $323 in cash and $1,725
      in notes receivable with interest rates of 9.5% and 10%. In addition, the
      Company entered into equipment rental agreements with the respective
      buyers of those projects to lease certain power generation equipment for
      annual rentals of $185 through December 31, 2002. The leases may be
      extended for six years at the option of the lessee.  Also, the annual
      rentals may be reduced if equipment is removed from the project sites by
      the Company in accordance with provisions in the rental agreements. In
      January 1994, these notes receivable were satisfied for $1,100, which
      reflects a $202 discount for early payment offered by the Company.

      During 1995, 1994 and 1993 the Company recognized approximately $2,975,
      $4,015 and $3,989, respectively, of revenues associated with the sale of
      natural gas to the Artesia project under a fuel management contract. The
      costs associated with the fuel transactions amounted to $2,975, $4,015
      and $3,989, respectively.

22.   LITIGATION SETTLEMENT COSTS

      In September 1993, the Company and certain subsidiaries and an equity
      affiliate entered into a settlement agreement with Hawker Siddeley Power
      Engineering Inc. and related entities, the turnkey contractor for the
      Hartford cogeneration plant. Pursuant to the settlement agreement, the
      Company relinquished its 5% general partner interest, paid Hawker $250
      and issued a promissory note for $250 to the succeeding general partner,
      which resulted in a total charge of $1,121 in fiscal 1993, which is
      included in selling, general and administrative expenses in the
      accompanying consolidated statement of operations.

23.   INVOLUNTARY CONVERSION GAIN

      On December 25, 1992, a fire disabled the Newark cogeneration plant. The
      damage to the plant caused by the fire has been repaired. The plant
      returned to partial operations in August 1993 and resumed full operation
      in October 1993. The Newark cogeneration plant generated revenues of
      $28,908, $23,082 (including net business interruption proceeds of $980)
      and $19,629 (including net business interruption proceeds of $5,880) in
      1995, 1994 and 1993, respectively. The Company received $36,000 from its
      insurance carrier which covered a substantial majority of the Company's
      cost of repair and loss of net profits due to business interruption.
      Additionally, the Company recognized an involuntary conversion gain of
      $6,066 in fiscal 1994.

      The increase in the valuation allowance from 1994 to 1995 is due
      primarily to the uncertainty of being able to realize more likely than
      not the benefits associated with loss carryforwards and future net
      deductible temporary differences generated in 1995 and an increased
      valuation allowance against the benefits associated with loss
      carryforwards generated prior to 1995.

      The Company has $36,012 of state net operating loss carryforwards
      available to offset state taxable income. These carryforwards will expire
      starting in 1996 and will continue to expire through 2010.

      The Company also has unused net operating loss carryforwards for United
      Kingdom income tax purposes. Using the exchange rate at June 30, 1995
      these loss carryforwards approximated $1,711. For United Kingdom tax
      purposes, these losses can be carried forward and can be used to offset
      future taxable income. However, due to the uncertainty of their ultimate
      realization, the Company has established a full valuation allowance
      against the benefits associated with these loss carryforwards.

      Additionally, a federal alternative minimum tax may be imposed at a 20%
      rate on the Company's alternative minimum taxable income which is
      determined by making statutory adjustments to the Company's regular
      taxable income. For alternative minimum tax purposes, loss carryforwards
      may offset only 90% of the Company's alternative minimum taxable income.
      The net operating loss carryforwards for alternative minimum tax purposes
      are approximately $32,750 at June 30, 1995. In 1992, the Company was
      subject to the alternative minimum tax which resulted in an alternative
      minimum tax expense of $84. This amount will be allowed as a credit
      carryover against future regular income tax expense and is not subject to
      expiration.

25.   TRANSACTIONS WITH RELATED PARTIES

      PoweRent Limited is 50% owned by the Company and 50% by an officer of a
      wholly-owned subsidiary. Amounts receivable from or payable to related
      parties are noninterest bearing and are classified as current, as
      settlement is expected to occur within one year.

      A summary of activity with related parties is as follows:

      (1)  The Company leases office space from Pennsport Partnership, a
           Pennsylvania partnership in which the former Chief Executive Officer
           and former Principal Stockholder (FCEO) of the Company has a 50%
           ownership interest.  Rental expense for 1995, 1994 and 1993 was
           $242, $289, and $293, respectively. The Company also leases office
           space from Christiana River Holdings, Ltd., an entity owned by the
           FCEO of the Company. Rental expense was $150 for fiscal 1995 and
           1994.

      (2)  In 1993, the Company recognized $156 of revenue by selling equipment
           and related services to PoweRent. The cost of the equipment and
           related service was $130.

      (3)  The Company also was charged commissions by O'Brien Power Systems,
           Inc. of $647 in 1994 in connection with equipment sales and services
           provided to third parties. In 1993, the Company recognized $346 of
           revenue by selling equipment and related services to O'Brien Power
           Systems, Inc., a company controlled by a relative of the FCEO of the
           Company. The cost of the equipment and related services was $322.

      (4)  In September 1993, O.B. Power Plant Limited, a wholly-owned (U.K.
           subsidiary), ("Puma"), purchased its executive offices and its
           principal facility located in Ash, Canterbury, Kent, United Kingdom
           from III Enterprises Limited, an entity owned by the FCEO of the
           Company for approximately $800. The Company has estimated a fair
           value of these facilities indicating a value of approximately
           $1,100. However, predecessor cost of $498 has been used to record
           the assets purchased and the excess of the purchase price over III
           Enterprises Limited's historical net book value of these facilities
           has been reflected as an increase in the accumulated deficit. Prior
           to September 1993, Puma leased the facility from III Enterprises
           Limited with rental expense amounting to $66 and $156 in fiscal 1994
           and 1993, respectively.

      (5)  Subsequent to June 30, 1995, the Company obtained a working capital
           line of credit facility from NRG totaling $3,500 (see Note 32).

      In addition, the Company has had transactions with projects structured as
      partnerships in which the Company had or retains a general partnership
      interest (see Note 10).

26.   SEGMENT INFORMATION AND MAJOR CUSTOMERS

      The Company operates principally in two industry segments: the
      developing, owning and operating of biogas projects and the development
      and ownership of cogeneration and waste heat recovery projects (energy)

      Revenue by segment consists of sales to unaffiliated customers;
      intersegment sales are not significant. For the purpose of this
      presentation, development and other fees are considered revenues of the
      energy segment.

      Identifiable assets by segment are those assets that are used in the
      operations of each segment. Corporate assets are those not used in the
      operations of a specific segment and consist primarily of cash, notes
      receivable from officers and deferred financing costs. Investments in
      limited partnerships are included in the identifiable assets of the
      energy segment.

      Selling, general and administrative expenses have been allocated to the
      individual segments on the basis of segment revenues and geographical
      location.

29.   LITIGATION

      Hawker Siddeley
      The Company was involved in litigation with Hawker Siddeley Power
      Engineering, Inc. ("Hawker"), the turnkey contractor for the Parlin (the
      "Parlin Action") and former Salinas projects (the "Salinas Action"). In
      the aggregate, Hawker's lawsuits, as amended, sought compensatory damages
      of $15,000 and $3,000 from the Parlin and former Salinas Projects,
      respectively. In May 1994, Parlin, O'Brien Cogeneration Inc. II,
      wholly-owned subsidiaries, and O'Brien Environmental Energy, Inc. entered
      into a settlement agreement with Hawker Siddeley, Power Engineering,
      Inc., the ("Hawker Settlement Agreement"), other than a $1,500 Promissory
      Note ("Note") issued by the Company to Hawker Siddeley, no money was
      exchanged and O'Brien (Parlin) Cogeneration, Inc. was not obligated to
      pay the $5,100 contract price withheld and all parties dismissed their
      claims related to the Parlin Action. Pursuant to the Hawker Settlement
      Agreement, the Salinas Action, prior to being dismissed, required that
      the first payment under the Note be paid by October 6, 1994.

      The note became subject to the bankruptcy proceedings on September 28,
      1994 and paid with post petition interest on April 13, 1996 (see Note
      32).

      Newark Fire Deaths
      During September 1993 to November 1993, three actions were filed against
      Newark by survivors of three employees of the independent operator of the
      Newark Cogeneration facility who were killed as the result of a fire
      which occurred at the facility in December 1992. All three actions were
      settled and covered in full by the Company's insurance carrier.

      Other Proceedings
      On July 27, 1994, an alleged stockholder of the Company filed suit
      seeking money damages in an amount allegedly sustained by the
      stockholder. On September 15, 1994, two alleged debenture holders filed
      suit seeking money damages in an amount allegedly sustained by debenture
      holders who purchased debentures from September 28, 1992 through April
      12, 1994. The complaints name as defendants O'Brien Environmental Energy,
      Inc. and certain of its officers and directors. The complaints allege
      that O'Brien Environmental Energy, Inc. and the other defendants violated
      the Securities Exchange Act of 1934 and disseminated or were responsible
      for  the disseminating of a series of false and misleading statements
      concerning the Company's business, results of operations and future
      prospects. The Bankruptcy Court, by its confirmation order dated February
      13, 1996, limited the rights of these claimants against

      the reorganized Company to the extent of any recoveries available to the
      Company under the insurance policies providing any insurance coverage in
      respect to such claims.

      The reorganized Company is continuing its dispute of certain prepetition
      creditor claims as well as certain professional fees and administrative
      priority claims filed with the Bankruptcy Court. Although the Company
      cannot give definitive assurance regarding the ultimate resolution of the
      various claims described above, the Company does not presently believe
      the matters described above or the resolution thereof will have a
      material adverse impact on the Company's financial statements.

      (1)  The carrying amount of these items are a reasonable estimate of
           their value as of June 30, 1995.

      (2)  Prepetition liabilities are stated at the value of the amount
           expected to be approved by the court as allowed claims. Under the
           NRG plan of reorganization, primarily all allowed claims will be
           paid in full, along with post-petition interest.

      (3)  The fair value of interest rate swap in the amount at which it could
           be settled based on an estimate obtained from the dealer.

      Fair value estimates are made at a specific point in time, based on
      relevant market information about the financial instruments. These
      estimates are subjective in nature, involve uncertainties and are matters
      of significant judgment and therefore cannot be determined with
      precision. Changes in assumptions could significantly affect the
      estimates.

31.   SALE AND REPURCHASE OF PHILADELPHIA WATER DEPARTMENT PROJECT

      On November 12, 1993, the Company sold the capital stock of O'Brien
      (Philadelphia) Cogeneration, Inc. ("OPC") and Philadelphia BioGas Supply,
      Inc. ("Biogas"), wholly-owned subsidiaries, and issued 5.5 million
      warrants for Class A common stock to entities controlled by an unrelated
      private investor for $5,000 in cash. The warrants were exercisable at
      prices ranging from $4.00 to $6.00 per share and assigned a value of
      $1,300 which was reflected in additional paid-in capital. The primary
      assets of OPC and Biogas consist of a 20-year energy service agreement
      and a digester gas supply agreement with the Philadelphia Municipal
      Authority ("Authority").

      On August 5, 1994, the Company exercised its option to repurchase 83% of
      OPC and Biogas for $5,000. The Company continued to own and rent to OPC
      and Biogas the facilities and all related generation and associated
      equipment to the project during the period the project was owned by the
      unrelated private investor and accordingly recognized rental revenues of
      approximately $254 and $2,187 in fiscal 1995 and 1994, respectively.

      The repurchase agreement obligates OPC to distribute quarterly, 17% of
      its net earnings, as defined. These distributions totaled $209 in fiscal
      1995 and are recorded in interest expense in the consolidated statement
      of operations. The 17% minority interest retained by the private investor
      is represented by 100 shares of OPC series A preferred stock, $.01 par
      value and redeemable by the Company at its option for a price, as
      defined, equal to 17% of the present value of the projected income stream
      of the project as set forth in the repurchase agreement.  The private
      investor can also obligate the Company to repurchase all, but not less
      than all, of

      the outstanding preferred stock at 60% of the Company's redemption price.
      The Company's redemption price at June 30, 1995 was approximately $2,084.

      None of the Company's Class A common stock warrants issued to the private
      investor on November 12, 1993 have been exercised. Under the terms of the
      NRG plan of reorganization, the warrants were terminated on the April 30,
      1996 closing date.

32.   SUBSEQUENT EVENTS

      Emerging from bankruptcy
      The Company emerged from bankruptcy on April 30, 1996 under a court
      approved plan of reorganization submitted by NRG. NRG acquired an
      approximate 42% equity interest on the April 30, 1996 closing date. The
      Company was renamed to NRGG (see Note 1).

      NRG funded $107,418 on the closing date. NRGG received $99,918 of which
      $71,240 was advanced under the terms of the ("NRG-New Loans"); $21,178
      was allocated as an equity contribution and $7,500 was designated as
      proceeds for the sale of 10 wholly-owned subsidiaries to NRG. In
      addition, NRG transferred $7,500 directly to the Company's stock transfer
      agent representing a cash distribution by NRG to the current common
      stockholders.

      On April 30, 1996, the outstanding Class A and Class B common shares of
      the Company were canceled and exchangeable for a new single issue of
      common stock of NRGG. NRGG authorized 50,000,000 shares, par value $.01.
      Additionally, the reorganized company authorized 50,000 shares of a new
      Series A preferred stock, par value $.01. The preferred stock is
      cumulative with a cash dividend per share at a rate per annum equal to
      the lesser of 14% or 400 basis points above the rate of interest being
      paid on the NRG loan to the Company. The total new common shares issued
      were 6,474,814 of which 2,710,357 (41.86%) are owned by NRG.
      Additionally, 49,574 shares of preferred stock were issued to Wexford in
      accordance with the plan of reorganization and subsequently redeemed,
      with dividends, paid on May 23, 1996 from proceeds of the new project
      financing loan.

      Prepetition liability funding
      Generally, all undisputed prepetition liabilities approved by the court
      as allowed claims were fully funded (or cured/reinstated) and paid with
      post-petition interest on the closing date. Certain proofs of claims,
      filed with the bankruptcy court, however, remain in dispute. An

      escrow fund was established to fully reserve for these disputed claims.
      Any remaining funds resulting from the Court disallowing any of these
      disputed claims will be disbursed prorata to all allowed non-reinstated
      creditor claimholders as additional post-petition interest. An
      approximate allocation of the $99,918 funding to NRGG is as follows:

                     Prepetition liabilities                   $  76,129

</TABLE>

      Additionally, prepetition liabilities of approximately $4,957 consisting
      primarily of subordinated debentures owned by Wexford Management Corp.
      were satisfied by the issuance of preferred shares in the reorganized
      company.  These shares were subsequently redeemed in May 1996 from the
      new project financing proceeds.

      Sale of subsidiaries to NRG
      Under the terms of the plan of reorganization, NRG purchased the stock of
      10 wholly-owned subsidiaries from the Company for $7,500 on April 30,
      1996. The companies sold (collectively "the subsidiaries") were O'Brien
      Biogas I (SKB), O'Brien Biogas Inc. VI, O'Brien Biogas (Mazzaro) Inc.,
      O'Brien Biogas (Corona) Inc., O'Brien Biogas Inc.  IV, O'Brien Biogas
      (Hackensack) Inc., O'Brien Biogas Inc. III (Atochem), O'Brien Biogas VII,
      O'Brien Cogen Inc. II (Artesia) and O'Brien Standby Power Energy, Inc.

      The subsidiaries sold include all of the Company's biogas projects
      (operating and those in development), the general partner holding a 3%
      equity interest in the Artesia Cogeneration partnership and a standby
      power project placed in service on December 31, 1995. Assets included on
      the June 30, 1995 consolidated balance sheet attributable to the
      subsidiaries total $10,458. The fiscal 1995 consolidated statement of
      operations include $1,315 in revenues and income (loss) from operations
      attributable to the subsidiaries of $(4,021) which includes an allocation
      of the equipment appraisal writedown of $2,839.

      Debtor-in-Possession financing
      On August 30, 1995, the Company and NRG with the approval of the Court,
      entered into a Chapter 11 financing agreement ("DIP financing") which
      provided for a $3,000 commitment with interest at 2% over prime. The loan
      commitment was increased on February 22, 1996 by an additional $500. The
      Company made periodic drawdowns totaling $3,450 through the April 30,
      1996 closing date. The agreement required monthly interest-only payments.
      The principal balance was repaid to NRG from the project refinancing in
      May 1996.

      Amendment to Newark and Parlin Power Purchase Agreements
      The Company renegotiated the Power Purchase Agreements ("PPAs") for the
      Parlin and Newark projects in early 1996.  Effective May 1, 1996, Parlin
      began operating as an Electric Wholesale Generator ("EWG") for the
      remaining term of the original contract. Historically, both projects have
      operated as Qualifying Facilities ("QF's"). The primary commercial
      difference is that under the amended PPAs, the project's customer
      supplies and pays for the cost of fuel. Until May 1, 1996, Newark and
      Parlin have incurred the cost of fuel as well as the risk of fluctuating
      prices. Although energy revenues as well as cost of energy revenues are
      anticipated to decrease under the new contracts, it is believed that
      operating gross profit margins will remain similar to historical results.
      However, margin fluctuations attributable to periodic swings in fuel
      costs will be eliminated. Additionally, the Parlin project has changed
      from a full base load operation to a half base load/half dispatchable
      project and the operating requirements relating to QF status have been
      eliminated.

      New project financing
      On May 17, 1996, Newark and Parlin entered into a Credit Agreement ("the
      new agreement") with a new lender. The new agreement established
      provisions for a $155,000 15 year amortizing loan, a $77,500 interest
      rate swap agreement and a $5,000 debt service reserve line of credit
      facility. On July 11, 1996, the new agreement became a joint and several
      liability of both the Newark and Parlin projects.

      On May 23, 1996, Newark borrowed $60,000 in the form of a six-month term
      loan under the terms of the new agreement. Also effective May 23, 1996,
      NRG Energy, Inc. guaranteed payment of pre-existing liabilities of Newark
      and Parlin up to $5,000 which will be reduced as certain defined
      milestones are reached and will be eliminated no later than May 23, 2001.
      The proceeds were used, among other things, to repay the Newark
      nonrecourse project financing and the DIP financing, redeem the Wexford
      preferred stock, and to reduce the NRG-New Loans.

      On June 28, 1996, NRG advanced approximately $56,000 to payoff the Parlin
      nonrecourse financing which included a $3,100 cost to terminate the
      interest rate swap agreement. On July 11, 1996, an additional $95,000 was
      borrowed pursuant to the new agreement and combined with Newark's six
      month term loan which was converted into a $155,000 15 year amortizing
      term loan under the terms of the new agreement. Proceeds of this
      borrowing were used to repay $56,000 to NRG, obligations of NRGG as well
      as to fund certain required reserve accounts under the terms of the new
      agreement. Also effective July 11, 1996, NRGG guaranteed repayment of up
      to $25,000 of the term loan and that payment of all income and franchise
      taxes of Parlin and Newark would be paid when due. NRG is required to
      maintain an investment of not less than $29,000 in the Company during the
      term of the new agreement.

      Collateral for the term loan includes a perfected first security interest
      on all assets of Newark and Parlin and a pledge of all capital stock of
      both Newark and Parlin.

      New NRG loans
      In accordance with the plan of reorganization, NRG and NRGG executed
      three loan agreements on April 30, 1966 ("the NRG - New Loans") with
      commitments of $45,000, $24,000 and $15,855 at annual interest rates of
      9.5%, 9.5% and 9%, respectively. On April 30, 1996, the NRG funding
      included $71,240 drawn under these NRG - New Loans. There remains $13,615
      available to the Company under one of the NRG - New Loans which obligates
      NRG to fund, if needed, a court established reserve to adequately cover
      the anticipated administrative, priority and tax claims that are
      contingent, unliquidated or unmatured or for allowed claim amounts which
      were undetermined on the April 30, 1996 closing date.

      O'Brien Schuylkill Note and Stock Option Agreement
      In March 1996, NRG and O'Brien (Schuylkill) Cogen ("OSC"), a wholly-owned
      subsidiary of the Company, entered into a $10,000 loan agreement ("the
      note") to provide a means of funding an OSC capital contribution
      obligation to the Grays Ferry Partnership (see Note 10).  No amounts have
      yet been borrowed under the note.

      In connection with NRG's assistance with the Gray's Ferry project, its
      financing and the note, the Company granted NRG the right, approved by
      the bankruptcy court in March 1996, to convert a portion of borrowings
      under the note to common stock of NRGG.  The option agreement provides
      that NRG can convert $3,000 of borrowings under the note for common stock
      of the reorganized Company which would equal, on a fully diluted basis,
      5.76% of the shares of common stock of the Company as of the NRG Plan
      Effective Date, April 30, 1996.
