                               TRINIDAD GUARANTEE


    This TRINIDAD GUARANTEE (this "Guarantee") is entered into as of
August 4, 1998 by YORK HOLDINGS (BARBADOS) SRL, a society with restricted
liability organized in Barbados (the "Guarantor"), in favor of THE BANK OF
NEW YORK, a New York banking corporation, under that certain Indenture described
in the recitals below, and as Collateral Agent under the Intercreditor Agreement
for the benefit of the Secured Parties (in such capacities, the "Collateral
Agent"). All capitalized terms used herein but not specifically defined shall
have the respective meanings given to such terms in Appendix A to the
Indenture, which Appendix A is hereby incorporated herein by reference as if
set forth in full herein.

                              W I T N E S S E T H:

    WHEREAS, York Power Funding (Cayman) Limited (the "Funding Company") is a
limited liability company organized under the laws of the Cayman Islands for
the sole purpose of issuing the Securities pursuant to the Indenture and
making loans to the Project Borrowers from the proceeds of such issuance;

    WHEREAS, the Funding Company has on the date hereof issued and sold
Securities in the principal amount of $150 million;

    WHEREAS, the principal and interest payments on the Securities will be
partially serviced by repayment of a loan made by the Funding Company to the
Trinidad Project Borrower and guaranteed by the Trinidad Guarantor subject to
the conditions set forth in the Indenture;

    WHEREAS, the Funding Company will loan $100 million of the proceeds of
issuance of the Securities to the Trinidad Project Borrower, which will be
contributed by the Trinidad Project Borrower to the Trinidad Guarantor and
will be loaned by the Trinidad Guarantor to the Trinidad Obligor pursuant to
the Trinidad Loan Agreement; and

    WHEREAS, the Guarantor is a subsidiary of the Trinidad Project Borrower
and anticipates benefiting directly and indirectly from the Trinidad Project
Loan and, therefore, is willing to guarantee certain of the obligations of
the Trinidad Project Borrower thereunder in accordance with the terms hereof.

    NOW, THEREFORE, in consideration of the above premises and for other good
and valuable consideration, the receipt and adequacy of which are hereby
acknowledged, the parties hereto hereby agree as follows:

         1. (a) As set forth in this Guarantee, the Guarantor guarantees the
full payment of the Guaranteed Obligations (as hereafter defined) when due,
upon maturity, acceleration or otherwise; PROVIDED, HOWEVER, that no demand
under this Guarantee may be made, and no obligation to pay all or any portion
of the Guaranteed Obligations shall exist, unless at the time such demand
shall have been made there also shall have occurred and be continuing an
Event of Default under Section 5.1(a) of the Trinidad Project Loan Agreement
between the Trinidad Project Borrower and the Funding Company.

<PAGE>

              (b) The Guarantor hereby and unconditionally agrees that upon
any failure by the Trinidad Project Borrower to pay, when due, of any of the
Guaranteed Obligations, the Guarantor will promptly pay the same. Each and
every failure in the payment of any of the Guaranteed Obligations shall give
rise to a separate cause of action under this Guarantee, and separate suits
may be brought against the Guarantor hereunder as each cause of action arises.

              (c) The Guarantor further agrees that this Guarantee
constitutes an absolute, present and continuing guarantee of payment and not
of collection and shall apply to all Guaranteed Obligations whenever arising
and waives any right to require that any resort be had by the Funding Company
after the failure (after giving effect to any applicable grace period) by the
Trinidad Project Borrower in making such payment to the Funding Company
rights against any other Person, or any other right or remedy available to
the Funding Company by contract, Applicable Law or otherwise.

         2. Guaranteed Obligations as used herein shall mean all principal,
interest, fees, charges, penalties, expenses, payments and all other amounts
due on or with respect to the Trinidad Project Note or otherwise pursuant to
the Trinidad Project Loan Agreement (the "Guaranteed Obligations").

         3. The liability of the Guarantor under this Guarantee in respect of
the Guaranteed Obligations shall be absolute and unconditional and shall not
be affected or released in any way, irrespective of:

              (a) any lack of validity or enforceability of the Trinidad
Project Loan Agreement, the Trinidad Project Note or any of the other
Transaction Documents;

              (b) any change in the time, manner or place of payment of, or
in any other term of any of the Guaranteed Obligations or amendment or waiver
of, or any consent to any departure from, any Transaction Document,
including, without limitation, any increase in the Guaranteed Obligations or
other obligations of the Trinidad Project Borrower under the Trinidad Project
Loan Agreement.

              (c) any enforcement of any Transaction Document, including the
taking, holding or sale of any collateral, or any termination or release of
any collateral from the liens created by any Transaction Document or the
non-perfection of any liens created by any Transaction Document;

              (d) any change, restructuring or termination of the structure
or existence of the Funding Company or the Trinidad Project Borrower;

              (e) any Event of Default of the Funding Company under
Section 5.1 of the Indenture; or

              (f) any Event of Default of the Trinidad Project Borrower under
Section 5.1 of the Trinidad Project Loan Agreement.

    This Guarantee shall continue to be effective or be reinstated, as the
case may be, if at any time any payment of any of the Guaranteed Obligations
is rescinded or must otherwise be returned by the Collateral Agent or any
other Person upon the insolvency, bankruptcy or reorganization of, the
Trinidad Project Borrower or the Guarantor, or otherwise, all as though such
payment had not been made.

         4. The obligations hereunder are independent of the obligations of
the Trinidad Project Borrower, and a separate action or actions may be
brought and prosecuted against the Guarantor whether action is brought
against either the Trinidad Project Borrower, or whether the Trinidad Project
Borrower be joined in any such action or actions, and to the extent permitted
by Applicable Law, the Guarantor waives the benefit of any statute of
limitations affecting its liability hereunder.

         5. The Guarantor authorizes the Funding Company or the Bond Trustee,
as applicable, acting pursuant to the Trinidad Project Loan Agreement,
without notice or demand and without affecting its liability hereunder, from
time to time, whether before or after termination of this Guarantee, to (a)
renew, compromise, extend, accelerate or otherwise change the time for
payment of the obligations of the Trinidad Project Borrower under the
Trinidad Project Loan Agreement or any part thereof, (b) take and hold
security for the payment of this Guarantee or the Guaranteed Obligations, and
exchange, enforce, waive, release, fail to perfect, sell, or otherwise

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

indirectly, principally, or as one of its important activities, in the
business of extending, or arranging for the extension of, credit for the

warranties made by the Guarantor and each of its Affiliates, and to its

         9. The Guarantor hereby irrevocably waives, to the extent permitted
by Applicable Law, any claim or other rights which it may now or hereafter
acquire against the Trinidad Project Borrower, whether due or to become due,
voluntary or involuntary, absolute or contingent, liquidated or unliquidated,
determined or undetermined, including, without limitation, any right of
subrogation, reimbursement, exoneration, contribution, indemnification, any

Trinidad Project Borrower or the Guarantor makes a payment or payments to the
Funding Company, or the Collateral Agent receives any proceeds of Collateral,

declared to be fraudulent or preferential set aside or otherwise required to
be repaid to either the Trinidad Project Borrower, its estate, trustee,
receiver or any other party, including, without limitation, under any
bankruptcy law, state or federal law, common law or equitable cause, then to
the extent of such payment or repayment, the obligation or part thereof which
has been paid, reduced or satisfied by such amount shall be reinstated and
continued in full force and effect as of the date such initial payment,
reduction or satisfaction occurred. The Guarantor shall defend or indemnify
the Funding Company from and against any claim or loss under this Section 8
(including reasonable attorneys' fees and expenses) in the defense of any
such action or suit.

Agent has no duty at any time to disclose to the Guarantor any information
relating to the business operations or financial condition of the Trinidad
Project Borrower.

         12. To the extent that the waiver set forth in SECTION 7 is or is
deemed to be ineffective or inapplicable, any obligations of the Trinidad
Project Borrower to the Guarantor, now or hereafter existing, are hereby
subordinated to the Guaranteed Obligations. If the Collateral Agent so
requests, after the occurrence of an Event of Default under the Trinidad
Project Loan Agreement, such obligations of the Trinidad Project Borrower to
the Guarantor shall be enforced and performance received by the Guarantor as
trustee for the Collateral Agent and the proceeds thereof shall be paid over
to the Collateral Agent on account of the Guaranteed Obligations, but without
reducing or affecting in any manner the maximum liability of the Guarantor
under the other provisions of this Guarantee.

         13. The Collateral Agent may, without notice to the Guarantor and
without affecting the Guarantor's obligations hereunder, assign this
Guarantee, in whole or in part in accordance with the provisions of the
Trinidad Project Loan Agreement and the Intercreditor Agreement. The
Guarantor agrees that the Collateral Agent may, subject to the provisions of
the Trinidad Project Loan Agreement, disclose to any prospective purchaser
and any purchaser of all or part of the Guaranteed Obligations any

                                      -14-

Guarantor, this Guarantee and any security for this Guarantee.

         14. The Guarantor agrees to pay all reasonable attorneys' expenses
and fees and all other fees and expenses which may be incurred by the
Collateral Agent in the enforcement of this Guarantee.

         15. The Collateral Agent agrees that no partners, directors,
officers, shareholders or employees or agents of the Guarantor shall in any
way be liable for the payment of the Trinidad Project Note or any sums now or
hereafter owing under the terms of, or for the performance of any obligation
contained in, this Guarantee.

         16. No modification or waiver of any of the provisions of this
Guarantee shall be binding on the Collateral Agent, except as expressly set
forth in a writing duly signed and delivered by the Collateral Agent acting
pursuant to the terms of the Intercreditor Agreement.

         17. This Guarantee shall be binding upon and inure to the benefit of
the Guarantor and the Collateral Agent for the benefit of the Secured Parties
and their respective successors and assigns; PROVIDED that the Guarantor
shall not assign its rights or the Guaranteed Obligations created under this
Guarantee without the prior written consent of the Collateral Agent.

         18. In case any provision of this Guarantee, the Trinidad Project
Loan Agreement or the Trinidad Project Note shall be invalid, illegal or
unenforceable in any jurisdiction, the validity, legality and enforceability
of the remaining provisions or the Guaranteed Obligations, or of such
provision or the Guaranteed Obligations in any jurisdiction, shall not in any
way be affected or impaired thereby.

         19. This Guarantee shall be governed by and construed according to
the laws of the State of New York.

         20. This Guarantee embodies the entire agreement and understanding
between the parties hereto and supersedes all prior agreements and
