drawing, each such advance being hereinafter referred to as a "Tender Advance."
The Company shall repay to Agent, for the ratable benefit of Lenders, the amount

by, or assets held by, or deposits in or for the account of, any Lender or the
Letter of Credit Bank or (ii) impose on any Lender or the Letter of Credit Bank
any other condition regarding this Agreement or the Letter of Credit, and the
result of any event referred to in clause (i) or (ii) of this subsection shall
be to increase the cost to any Lender or the Letter of Credit Bank of issuing or
maintaining the Letter of Credit, then, within ten days of receipt of written
demand from Agent, the Company shall pay to Agent (on behalf of any such Lender
or the Letter of Credit Bank, as the case may be) all additional amounts which
are necessary to compensate such Lender or the Letter of Credit Bank, as the
case may be, for such increased cost incurred by such Person. All payments of
increased cost pursuant to this subsection shall bear interest thereon if not
paid within ten days of such notice until payment in full thereof at the Default
Rate. A certificate as to such increased cost incurred by any such Lender or the
Letter of Credit Bank, as the case may be, as a result of any event mentioned in
clause (i) or (ii) of this subsection and setting forth the additional amount or
amounts to be paid to Agent hereunder shall be prepared in good faith and
submitted by Agent to the Company and shall be conclusive (absent manifest
error) as to the amount thereof. In determining such amount, Agent may use any
reasonable averaging and attribution methods.

            (h) Reduced Return. If after the date hereof any Lender shall have
determined that the adoption of any applicable law, rule or regulation regarding
capital adequacy, or any change therein, or any change 


                                      -4-


in the interpretation or administration thereof by any Governmental Authority,
central bank or comparable agency charged with the interpretation or
administration thereof, or compliance by such Lender with any request or
directive regarding capital adequacy (whether or not having the force of law) of
any such Governmental Authority, central bank or comparable agency has the
effect of reducing the rate of return on the capital of such Lender as a
consequence of such Lender's obligations to reimburse the Letter of Credit Bank
for drawings under the Letter of Credit to a level below that which such Lender
could have achieved but for such adoption, change or compliance (taking into
consideration such Lender's policies with respect to capital adequacy) then,
upon notice of such change by Agent by submission to the Company of the
certificate hereinafter described, the Company shall within ten days of receipt
of such notice, pay to Agent (on behalf of such Lender) such additional amount
or amounts as will compensate such Lender for such reduction. All payments
pursuant to this subsection (g) shall bear interest thereon if not paid within
ten days of such notice until payment in full at the Default Rate. A certificate
of Agent claiming compensation under this subsection (g) and setting forth the
additional amount or amounts to be paid to it hereunder shall be prepared in
good faith and submitted by Agent to the Company and shall be conclusive in the
absence of manifest error. In determining such amount, Agent may use any
reasonable averaging and attribution method.

            (i) Overdue Amounts. The Company shall pay to Agent, for the ratable
benefit of Lenders, interest on any and all amounts unpaid by the Company when
due hereunder (in the case of amounts in respect of interest, to the maximum
extent permitted by law) for each day from the date such amounts become due
until payment in full, payable on demand, at the Default Rate; provided, that
such fluctuating interest rate shall in no event be higher (with respect to each
amount due and payable hereunder, from the date such amount is due and payable
until the date such amount is paid in full) than the maximum rate permitted by
applicable law.

and performance by the Company of this Agreement and the Related Documents to
which it is, or is to be, a party are within the Company's corporate powers,
have been duly authorized by all necessary corporate action, and do not and will
not contravene, or constitute a default under, any Contractual Obligation or
Requirement of Law of the Company, or result in the creation or imposition of
any Lien on any asset of the Company or any Subsidiary (other than pursuant to
the Related Documents).

            (c) Binding Effect. This Agreement and the Related Documents to
which the Company is, or is to be, a party constitute, or will constitute, when
executed and delivered in accordance with their terms, valid and binding
agreements of the Company.

to the knowledge of the Company, threatened against or affecting the Company or
any Subsidiary before any court or arbitrator or any Governmental Authority in
which there is a reasonable possibility of an adverse decision which could

to perform its obligations under this Agreement or any Related Document to which
it is, or is to be, a party, or which in any manner questions the validity of
this Agreement or any such Related Document.

            (f) Government Authorization. No authorization or approval of, or
other action by, and no notice to or filing with, any Governmental Authority is

Company to Agent for purposes of, or in connection with, this Agreement or any
transaction contemplated hereby is, and all such information hereafter furnished
by the Company to Agent will be, true and accurate in all material respects on
the date as of which such information is stated or certified. The Company has
disclosed to Agent in writing any and all facts that could reasonably be

Company can now reasonably foresee), the business, financial condition, results
of operations or prospects of the Company and its Subsidiaries, taken as a
whole, or the ability of the Company to perform its obligations under this
Agreement and the Related Documents.

      The representations and warranties contained or incorporated herein shall

date of each drawing under the Letter of Credit.

      The Company may, at any time and from time to time, update the accuracy of
any representation or warranty contained herein by providing written notice
thereof to Agent, provided, however, in no event may the Company so amend any
such representation or warranty if the existence of the information contained in
such amendment would reflect or evidence a Default or Event of Default.

      SECTION 7. Covenants. The Company agrees that during the term of this
Agreement:

            (a) Certain Covenants. Except as may be otherwise provided in this
Section 7, the Company will perform, comply with and be bound by, for the
benefit of Agent and Lenders, each of its agreements, covenants and obligations
contained in the Credit Agreement, each of which (together with the related
definitions and ancillary provisions) is hereby incorporated herein by
reference.


                                      -8-


            (b) Use of Proceeds. The proceeds of the sale of the Bonds shall not
be used in such a manner as to cause any of the Bonds to be treated as
"arbitrage bonds" within the meaning of Section 148 of the Code (or any
successor provision thereto) and the regulations promulgated or proposed
thereunder.

            (c) Governmental Authorizations. The Company will do and cause to be
done all things necessary to comply with all Requirements of Law applicable to
it, and obtain, and take all necessary or appropriate action to ensure the
continuance of, all consents, licenses, filings, registrations, approvals or
authorizations of or with any Governmental Authority which may at any time be
required with respect to the validity and enforceability of this Agreement and
the Related Documents to which the Company is, or is to be, a party, the
obligations of the Company hereunder and thereunder and the performance hereof
and thereof.

            (d) Amendments, Etc. The Company will not amend or otherwise permit

            (f) Independence of Covenants and Representations. The Company will
not exercise its rights under the Related Documents to direct the Issuer to call
the Bonds (or any portion thereof) for optional redemption, unless the Company
first demonstrates to the reasonable satisfaction of Agent that at the time of
such redemption the Letter of Credit Bank and each Lender will be fully
reimbursed with respect to all drawings under the Letter of Credit in connection
with such redemption.

            (g) Independence of Covenants and Representations. All covenants and
representations contained herein shall be given independent effect, so that if
any action or condition would violate any of such covenants (or would breach any
of such representations at any time made or deemed made), the fact that such
action or condition would not violate or breach another covenant or
representation shall not avoid the violation or breach of any such covenant or
representation.

same, which shall automatically become due and payable);

                  (ii) notify the Trustee of the occurrence of an Event of

Default or an Event of Default under the Credit Agreement or any other document
or agreement to which the Company is a party or otherwise subject other than the
Letter of Credit

indemnification provided above is in addition to any other rights (including
without limitation rights to indemnity) which Agent, each Lender and the Letter
of Credit Bank, as applicable, may be entitled to at law, by contract (including
without limitation the Credit Agreement) in equity or otherwise. Nothing in this
Section is intended to limit the Company's payment obligations contained in
subsection (a) of Section 2 hereof.

paid and satisfied in full and shall (x) be binding upon the Company and its
successors and assigns and (y) inure to the benefit of and be enforceable by

provided, however, that (i) the Company may not assign all or any part of its
rights or obligations under this Agreement without the prior written consent of
Agent and (ii) the obligations of the Company pursuant to Section 13 shall
survive the termination of this Agreement.

            (b) Any Lender may at any time sell or grant participations to any

such Lender's rights and benefits under this Agreement in which event the
Participant shall not have any rights hereunder (the Participant's rights
against such Lender to be as set forth in the agreement executed by such Lender
in favor of the Participant) and all amounts payable by the Company hereunder
shall be determined as if such lender had not sold or granted any participation.

      SECTION 15. Grant of Security Interest. To secure the Company's
obligations to Agent and Lenders hereunder and all other Obligations, the

for the equal and ratable benefit of the owners of the Bonds and the Agent, a
security interest in all of the Trust Estate under and as defined in the
Indenture and (2) hereby grants to Agent, for the ratable benefit of Lenders, a
security interest in all of the Company's goods hereafter acquired with the
proceeds of the Bonds and all replacements and substitutions therefor and all
proceeds and products thereof. The Company covenants and agrees that it will
defend Agent's rights and security interests created by this Section against the
claims and demands of all Persons. In addition to its other rights and remedies

remedies of a secured party under the Uniform Commercial Code or other
applicable law with respect to the security interests created by this Section.
Agent's rights under this Section are in addition to, and not in lieu of, its
rights and security interests under the Credit Agreement.

amendment to, or waiver of, (i) the Credit Agreement Representations, (ii) an
Event of Default under and as defined in the Credit Agreement or (iii) the
covenants from the Credit Agreement referred to in Section 7(a) hereof, which
has been consented to by Agent, shall be deemed to be incorporated herein by
reference and shall become effective hereunder when such amendment or waiver
becomes effective thereunder, without any further action necessary by either the
Company or Agent. Any such amendment or waiver shall be effective only in the
specific instance and for the specific purpose for which given.

            (b) The Credit Agreement Representations and the covenants from the
Credit Agreement referred to in Section 7(a) hereof incorporated herein by
reference, will be deemed to continue in effect for the benefit of Agent and
Lenders until the Letter of Credit has terminated and all amounts due hereunder

responsible for: (a) the use which may be made of the Letter of Credit or for
any acts or omissions of the Trustee, the Tender Agent and any beneficiary or
transferee in connection therewith; (b) the validity, or genuineness of
documents, or of any endorsement(s) thereon, even if such documents should in

any other circumstances whatsoever in making or failing to make payment under
the Letter of Credit, except only that the Company shall have a claim against
Agent, any Lender or the Letter of Credit Bank, as applicable, to the extent,
but only to the extent, of any direct, as opposed to consequential, damages
suffered by the Company which the Company proves were caused by (i) Agent's, any
Lender's or the Letter of Credit Bank's, as applicable, willful misconduct or
gross negligence in determining whether documents presented under the Letter of
Credit comply with the terms thereof or (ii) the Letter of Credit Bank's willful
failure to pay under the Letter of Credit after the presentation to it by the
Trustee (or a successor under the Indenture to whom the Letter of Credit has
been transferred in accordance with its terms) of a draft and certificate
strictly complying with the terms and conditions of the Letter of Credit. In
furtherance and not in limitation of the foregoing, the Letter of Credit Bank,
may accept documents that appear on their face to be in order, without
responsibility for further investigation, regardless of any notice or
information to the contrary.

      SECTION 19. Costs, Expenses and Taxes. The Company agrees to pay on demand
all out-of-pocket expenses of Agent, Lenders and the Letter of Credit Bank,

determined to be payable in connection with the execution, delivery, filing and
recording of this Agreement and such other documents and agrees to save Agent
and Lenders harmless from and against any and all liabilities with respect to or
resulting from any delay in paying or omission to pay such taxes and fees.

      SECTION 20. Severability. Any provision of this Agreement which is
prohibited, unenforceable or not authorized in any jurisdiction shall, as to
such jurisdiction, be ineffective to the extent of such prohibition,
unenforceability or non-authorization without invalidating the remaining
provisions hereof or affecting the validity, enforceability or legality of such
provision in any other jurisdiction.

      SECTION 21. Agent's Agreements. The Agent acknowledges that (a) during the
term of this Agreement and so long as no Event of Default has occurred and is
continuing hereunder, it will comply with the terms and conditions of its
agreement with the Letter of Credit Bank regarding the Letter of Credit so as
not to permit a default to occur thereunder and (b) so long as no Event of
Default has occurred and is continuing under the Credit Agreement, the Agent
shall charge the Company's loan account with Agent under the Credit Agreement as
a Bond Letter of Credit Loan at the times and in the amounts necessary to pay
all amounts payable hereunder when due so as not to cause a default hereunder

FORUM.
