failure to comply could not reasonably be expected to have a Material Adverse
Effect. To the best knowledge of each U.S. Guarantor, each U.S. Project is in
compliance with all applicable Environmental Laws and there are no existing
facts, circumstances or conditions which could under any existing applicable
Environmental Law, individually or in the aggregate with all other circumstances
and conditions, reasonably be expected to result in a Material Adverse Effect.

         Section 3.7 EMPLOYEE BENEFIT PLANS. No U.S. Guarantor sponsors,
maintains, administers, contributes to, participates in or has any obligation to
contribute to or any liability under, any Plan, nor since the date which is six
(6) years immediately preceding the

Closing Date has any U.S. Guarantor established, sponsored, maintained,
administered, contributed to, participated in or had any obligation to
contribute to or any liability under, any Plan. A Termination Event has not
occurred with respect to any Plan the occurrence of which has resulted in or to
each U.S. Guarantor's best knowledge is reasonably likely to result in a
Material Adverse Effect. No U.S. Guarantor nor any ERISA Affiliate thereof has
failed to make a required contribution or payment to a Multiemployer Plan when
due, the failure of which has resulted in or to such U.S. Guarantor's best
knowledge is reasonably likely to result in a Material Adverse Effect. To the
best of any U.S. Guarantor's knowledge, no accumu lated funding deficiency as
defined in Section 412 of the Code has been incurred nor has any funding waiver
from the Internal Revenue Service been received or requested with respect to any
Pension Plan, nor has any U.S. Guarantor or any ERISA Affiliate thereof failed
to make any contribution or to pay any amount due and owing as required by
Section 412 of the Code, Section 302 of ERISA or the terms of any Pension Plan,
nor has there been any event requiring disclosure under Section 4041(c)(3)(C) or
Section 4063 of ERISA with respect to any Pension Plan, the event or occurrence
of which has resulted in or to any U.S. Guarantor's best knowledge is reasonably
likely to result in a Material Adverse Effect. To any U.S. Guarantor's best
knowledge, each U.S. Guarantor and each ERISA Affiliate thereof have met their
minimum funding requirements under ERISA and the Code with respect to the Plans,
and all benefit liabilities under each Pension Plan are being funded in
accordance with applicable legal requirements and reasonable actuarial
assumptions and methods as set forth in ERISA and the Code. To any U.S.
Guarantor's best knowledge, no material proceeding, claim, lawsuit and/or
investigation exists or is threatened concerning any Pension Plan or
Multiemployer Plan the occurrence of which has resulted in or to any U.S.
Guarantor's best knowledge is reasonably likely to result in a Material Adverse
Effect. No U.S. Guarantor nor to any U.S. Guarantor's best knowledge any ERISA
Affiliate thereof has incurred any liability to the PBGC other than for
insurance premiums with respect to a Pension Plan, the payment of which is not
yet due.

         Section 3.8 BUSINESS OF EACH U.S. GUARANTOR. Except as otherwise

defaults which could not reasonably be expected to result in a Material Adverse
Effect.

         (c) To the best knowledge of any US. Guarantor, no default exists by
any other party to any U.S. Project Document or any other contract related to
any U.S. Project and no event of force majeure exists under any U.S. Project
Document except for defaults which, in either case, could not reasonably be
expected to result in a Material Adverse Effect.

         (d) All amounts available to fund Equity Cash Flows and Note Cash Flows
to the BNY Guarantor and the Warbasse Guarantor have been used for such purpose
and such payments have been in accordance with the scheduled amounts for such
purposes.

         Section 3.14 GOVERNMENTAL APPROVALS. All Governmental Approvals which
are required to be obtained by, in the name of or on behalf of any U.S.
Guarantor or, to the knowledge of any U.S. Guarantor, any other party to any
Transaction Document in connec tion with (a) the issuance of the U.S. Project
Note and (b) the execution, delivery and performance by any U.S. Guarantor or
any other party to any Transaction Document of the Transaction Documents have
been duly obtained and are in full force and effect, other than, in each case,
those Governmental Approvals which the failure to so obtain could not reasonably
be expected to result in a Material Adverse Effect.

of extending, or arranging for the extension of, credit for the purposes of
purchasing or carrying any "margin stock" (as defined in Regulation, T, U or X
of the Board of Governors of the Federal Reserve System). No part of the
proceeds of the U.S. Project Loan will be used for "purchasing" or "carrying"

amendment, modification, supplement or waiver of, any of the provisions of, or
give any consent under, any insurance policy obtained by it (including amending,

         Section 6.2 AMENDMENTS AND WAIVERS. No waiver, amendment, modification
or termination of any provision of this Agreement, or consent to any departure

it may now or hereafter have to the laying of venue of any of the aforesaid
actions or proceedings arising out of or in connection with this Agreement or
any other Finance Document brought in the courts referred to in clause (b) above

such U.S. Guarantor hereunder or any obligation of such U.S. Guarantor for the
payment of any amount payable hereunder for any claim based on, arising out of

Non-Recourse Person under any Transaction Document to which it is party, (b) the
rights and remedies of Funding Company against any such Non-Recourse Person
under any Transaction Document to which any such Non-Recourse Person is a party,

instrument and any of the parties hereto may execute this Agreement by signing
any such counterpart.

         Section 6.12 SUCCESSORS AND ASSIGNS. All of the covenants, promises and
agreements in this Agreement by or on behalf of any U.S. Guarantor or Funding
Company shall bind and inure to the benefit of their respective successors and

assign or transfer all or any part of its rights and obligations under this
Agreement other than with the prior written consent of the Bond Trustee and in

                                  SCHEDULE 3.5

                                   LITIGATION


1. Appeal by the Office of Public Utility Counsel of the Public Utility
   Commission of Texas Order in Docket No. 15328, APPLICATION OF TEXAS
   UTILITIES ELECTRIC COMPANY FOR THE APPROVAL OF RENEWABLE RESOURCES
   AGREEMENT WITH NEW WORLD POWER TEXAS RENEWABLE ENERGY LIMITED PARTNERSHIP.

2. In February 1997, the general contractor of the Brooklyn Navy Yard Project
   brought an action in California against Brooklyn Navy Yard Cogeneration
   Partners, LP ("BNYCP") seeking damages of $137 million for amounts owed
   under the turnkey contract and denying liability under various claims.
   BNYCP responded to the complaint, denying all the allegations contained
   therein and commenced an action in New York against the general contractor
   denying any liability under the turnkey contract and seeking damages in
   excess of $13 million pursuant to various counterclaims. In addition,
   BNYCP has been named as one of the defendants in another action relating to
   the construction activity of the Brooklyn Navy Yard Project. Although it
   is a general partner of BNYCP, B-41 Associates, L.P. ("B-41") was not
   served in these complaints and is not a party to any of the actions. Edison
   Mission Energy, Inc. ("Mission") has agreed to indemnify both BNYCP and
   B-41 against any costs resulting from the contractor's action. B-41 has
   agreed to reimburse Mission for 25% of the excess over $10 million of such
   costs, if any, with an aggregate limit of $10 million, payable solely out
   of B-41's partnership fees and distributions and further limited to $1
   million per year for 1998, 1999 and 2000, and $2 million per year
   thereafter.

                                 PERMITTED LIENS


1. B-41 Associates, L.P. ("York Partners") granted to Edison Mission Energy,
   Inc. ("Mission") a security interest in its portion of the (a) certain
   general partner fees calculated as a percentage of the gross revenues (the
   "General Partner Fees") of Brooklyn Navy Yard Cogeneration Partners, L.P.
   ("BNYCP") and (b) royalty fees calculated as a percentage of gross
   revenues (the "Royalty Fees") of BNYCP, the Royalty Fees and its right to
   receive distributions pursuant to the BNYCP Limited Partnership Agreement,
