Section 3.01    The Project. Construction of the Project is complete. The Project is the property of the Company.

Section 3.02    Sale of Bonds and Deposit of Proceeds. In order to provide funds for the refunding of the Prior Bonds, the Authority, on the date specified in the Bond Purchase Agreement or as soon thereafter as practicable, and concurrently with the issuance and delivery to the Trustee of the Note as provided in Section 4.01 hereof, will issue, sell and deliver the Bonds, all pursuant to and as provided in the Bond Purchase Agreement and subject to the conditions set forth in Section 2.06 of the Indenture, and will deposit the proceeds of such sale including the accrued interest, if any, paid by the initial purchasers of the Bonds in the Project Fund.

Section 3.03     Disbursements from Project Fund. 1. The Authority has in the Indenture authorized and directed the Trustee to make payments from the Project Fund in accordance with Section 8.01 of the Indenture, to pay the redemption price of the Prior Bonds and costs related thereto upon receipt from time to time of letters signed by an Authorized Company Representative in accordance with Section 8.01 of the Indenture. Concurrently with the delivery by the Company of each such letter to the Trustee, the Company will deliver to the Authority a copy thereof and any attachments thereto. The Company will indemnify and save harmless the Authority and the Trustee from any liability incurred in connection with any letter so delivered and any payments made in reliance thereon.

2. All monies remaining in the Project Fund after the redemption of the Prior Bonds and payment of all costs related thereto shall, at the written direction of an Authorized Company Representative, be paid to the Company.

Section 3.04    Adequacy of Project Fund. The Company acknowledges that the monies in the Project Fund are not sufficient to pay the redemption price of the Prior Bonds and costs related thereto in full.

Section 3.05    Ownership and Possession of the Project.

NOTE AND PAYMENTS

Section 4.01    Execution and Delivery of Note to Trustee. Concurrently with the authentication by the Trustee and delivery by the Authority of the Bonds and in order to evidence the obligation of the Company to the Authority to repay the Bonds, the Authority hereby directs the Company, and the Company hereby agrees, to execute and deliver to the Trustee its Note, duly and validly executed and delivered, relating to the Bonds. The Note shall be in substantially the form attached hereto as Exhibit A with only such changes to such form as may be approved by the Authority. Thereafter, the Company shall be obligated to make the Note Payments, constituting payments of principal of, and premium, if any, and interest on the Note, and the Additional Payments required by this Participation Agreement.

Provision for payment in full of all amounts payable or to become payable under the Note shall be deemed to have occurred upon receipt by the Trustee of written notice from the Authority acknowledging that the Company has satisfied its obligations to the Authority under the Note. The Authority agrees to deliver such written notice to the Trustee promptly when such provision for payment in full has been made.

Section 4.02    Payments Payable; Note Payments; Additional Payments.

(a)The Company covenants and agrees to pay the Payments as and when the same are due and payable in accordance with the Note and this Section 4.02. The Company shall provide the Trustee with a written allocation of amounts paid under this Section 4.02 among the various purposes set forth in this Section 4.02.

(b)The Note Payments shall be in an aggregate amount sufficient for, together with other amounts held by the Trustee and available under the Indenture for application to, the payment in full of the Bonds consisting of (i) the total interest becoming due and payable on the Bonds to the date of payment thereof, and (ii) the total principal amount plus premium, if any, of the Bonds.

(c)The Company shall make Note Payments as set forth in Section 4.02(b) at or prior to the time the corresponding payment is due on the Bonds. Each installment of Note Payments paid by the Company shall be increased as may be necessary to make up any previous deficiency of any of the required payments and to make up any deficiency in the Bond Fund.

(d)In addition, the Company shall pay to the Registrar and Paying Agent for deposit in the Bond Purchase Fund and credit to the Company Account therein an amount sufficient to provide for the payment of the Purchase Price (as defined in the Bond Purchase Trust Agreement) of any Bond tendered for purchase pursuant to the Bond Purchase Trust Agreement to the extent that sufficient moneys are not available for the payment of such Purchase Price from the other sources described therein.

8

Exhibit 4.2.1

(e)The Company covenants that it shall deposit, or cause to be deposited with the Trustee, sufficient funds to assure that no default shall occur in the payment of the principal of or premium, if any, or the interest on, or the Purchase Price of, the Bonds as and when due, and that no unreasonable delay shall occur in the payment of the costs and expenses payable from Additional Payments.

(f)The Company further covenants and agrees to pay, when due and payable, as Additional Payments, certain additional amounts and costs and expenses. Each installment of Additional Payments, if any, shall be equal to the sum of the amounts set forth in clauses (i) to (iv), inclusive, below, and shall be paid directly to the persons entitled to such payments. "Additional Payments" is hereby defined to be the aggregate of the installments of the following:

(i)the reasonable fees and expenses payable to the Trustee, any Indexing Agent, the Registrar and Paying Agent, any issuer of a Support Facility (and in the case of Auction Rate Bonds, the Auction Agent under the Auction Agency Agreement, any Broker-Dealers under the respective Broker-Dealer Agreements, and any Remarketing Agent under the Remarketing Agreement), and of any counsel or agents of any of the foregoing;

(ii) all costs incurred in connection with the transfer, exchange, purchase or redemption of Bonds not otherwise paid by the holders thereof, including all charges of the Authority (and in the case of Auction Rate Bonds, the Auction Agent, any Broker-Dealer and any Remarketing Agent), the Registrar and Paying Agent and the Trustee with respect thereto, to the extent monies are not otherwise available therefor;

(iii)the reasonable fees and other costs incurred for services of such attorneys and accountants as are employed to make examinations, provide services, render opinions and prepare reports required under this Participation Agreement, the Tax Regulatory Agreement, the Bond Purchase Trust Agreement, and the Indenture; and

(iv)initial administration fees in the amount of $731,750 on the date of authentication and delivery of the Bonds to the initial purchasers thereof, an annual fee equal to $130 per million dollar principal amount of the Bonds on July 1, 2000 and on July 1 of each year thereafter, based upon the amount of Bonds Outstanding as of such July 1 and for purposes of the calculation of such fee, rounding up to the nearest whole million dollars, and all reasonable expenses, disbursements, advances, taxes, assessments or impositions, not otherwise paid under this Participation Agreement or the Indenture, incurred by or imposed upon the Authority in connection with its administration and enforcement of, and compliance with, this Participation Agreement, the Auction Agency Agreement, the Bond Purchase Trust Agreement, the Remarketing Agreement and the Indenture, which amounts the Company is obligated to pay, including, but not limited to, reasonable attorneys' fees. In addition, the Company shall deliver to the Authority a check payable to the State of New York with respect to a bond issuance charge applicable to the Bonds pursuant to Section 2976 of the Public Authorities Law of the State of New York in the amount specified by such section on the date of authentication and delivery of the Bonds.

9

Exhibit 4.2.1

(g) In the event that the Company shall fail to make any Payment as required by Sections 4.02(a) - (e) hereof, the Payment so in default shall continue as an obligation of the Company until the amount in default shall have been fully paid, and the Company agrees to pay the same with interest thereon, which interest shall also constitute an obligation of the Company at the maximum rate of interest payable on the Bonds pursuant to the Indenture, to the extent permitted by law, from the date of default until paid; provided, that the Company agrees in the event the Company shall fail to make any Payment during an Auction Rate Period, the Payment so in default shall continue as an obligation of the Company until the amount in default shall have been fully paid, and the Company agrees to pay the same with interest thereon, which interest shall also constitute an obligation of the Company at the Overdue Rate, to the extent permitted by law, from the date of default until paid. Nothing in this Section 4.02 shall require the Company to pay costs and expenses mentioned in clause (f)(iii) above so long as the validity or the reasonableness thereof shall be contested in good faith unless the Trustee shall receive an opinion of independent counsel that such contest jeopardizes the respective interests of the Authority and the Trustee in this Participation Agreement, the Auction Agency Agreement, the Bond Purchase Trust Agreement, the Indenture or the Remarketing Agreement, in which event the Company shall pay such costs and expenses (without prejudice to any rights of the Company to recover such costs and expenses if not valid or reasonable) to the end that the respective interests of the Authority and the Trustee, in the opinion of independent counsel, are not jeopardized.

Section 4.03    Notice to Pay; Medium of Payment; Acceleration. Failure to receive any prior notice of the due date of any Payment will not relieve the Company of its obligation to pay such Payment when it is due and payable. The Company covenants and agrees that it will pay or cause to be paid when due and payable hereunder the Payments, and every installment thereof, without notice or demand therefor and without abatement, reduction or set-off of any kind or nature whatsoever, in lawful money of the United States of America.

If pursuant to the provisions of Section 12.03 of the Indenture, the Bonds are accelerated or shall otherwise be declared due and payable immediately, then the Company shall forthwith pay or cause to be paid to the Trustee an amount sufficient with all other funds available therefor, to pay the Bonds in full and, secondly an amount which shall be sufficient, with all other funds available therefor, to pay all other obligations of the Authority or the Company incurred or to be incurred under the Indenture, this Participation Agreement, the Auction Agency Agreement, the Bond Purchase Trust Agreement or the Remarketing Agreement.

Section 4.04    Prepayment of Note Payments. The Note may be prepaid, in whole or in part, at the option of the Company in connection with an optional redemption of the Bonds pursuant to Article V of the Indenture and shall be prepaid, in whole or in part, in connection with any mandatory redemption of the Bonds pursuant to Article V of the Indenture other than a mandatory redemption pursuant to Section 5.07 of the Indenture. Prepayment of the Note pursuant to the preceding sentence shall be with or without premium, as required to provide sufficient funds to redeem the Bonds being redeemed pursuant to Article V of the Indenture. The Note also may be prepaid in whole or in part at any time, without premium, at the option of the Company subsequent to the redemption of the Bonds with moneys furnished by the State of New York pursuant to Section 5.07 of the Indenture.

10

Exhibit 4.2.1

The Company shall give notice to the Trustee and the Authority of any intention to prepay the Note in whole or in part and of the principal amount to be prepaid not more than sixty (60) nor less than thirty-five (35) days prior to the date on which such prepayment is to be made on the Note. Such optional prepayment may be made not later than one (1) Business Day prior to the date of prepayment of the Bonds.

The Company may also elect to provide for the defeasance of the Bonds in accordance with Article XV of the Indenture and upon the defeasance of the Bonds, the Note will be deemed paid, in whole or in applicable part.

Section 4.05    Company's Payments as Trust Funds. All Note Payments and Additional Payments required to be made by the Company under this Participation Agreement and the Note to the Authority, the Trustee or the Registrar and Paying Agent which under the Indenture are required to be applied in payment of or as security for the Bonds, shall be and constitute and are hereby declared to be trust funds, whether held by the Authority, the Trustee, the Registrar and Paying Agent, or any bank or trust company, designated for such purpose and shall continue to be impressed with a trust until such monies are applied in the manner provided in the Indenture.

Section 4.06    Absolute Obligation to Make Payments. The obligation of the Company to pay the Note Payments and the Additional Payments, as required by this Participation Agreement and the Note, and to satisfy any other financial liabilities incurred hereunder and thereunder shall be an absolute, direct, general obligation, and shall be unconditional and shall not be abated, rebated, set off, reduced, abrogated, waived, diminished or otherwise modified in any manner or to any extent whatsoever (other than for prior payment), regardless of any rights of set-off, recoupment or counterclaim that the Company might otherwise have against the Authority or the Trustee or any other party or parties and regardless of any contingency, act of God, event or cause whatsoever and notwithstanding any circumstance or occurrence that may arise or take place including, but without limiting the generality of the foregoing, the following:

(a)any damage to or destruction of any part or all of the Project;

(b)the taking or damaging of any part or all of the Project by any public authority or agency in the exercise of the power of eminent domain or otherwise;

(c)any assignment, novation, merger, consolidation, transfer of assets, subleasing or other similar transaction of or affecting the Company whether with or without the approval of the Trustee, except as otherwise expressly provided in this Participation Agreement;

(d)with respect solely to the obligation of the Company to pay the Additional Payments, the termination of this Agreement and payment or provision for payment in full of the amount due under the Note pursuant to the provisions hereof;

(e)any failure of any party to perform or observe any agreement or covenant, whether express or implied, or any duty, liability or obligation arising out of or in connection with this Participation Agreement, the Note, the Auction Agency

(f)any change or delay in the time of availability of the Project or any part thereof for use of the Project or any part thereof;

(g)any acts or circumstances that may constitute an eviction or constructive eviction from any part of the Project;

(h)failure of consideration, failure of title to any part of the Project or commercial frustration; and

(i) any change in the tax or other laws of the United States or of any state or other governmental authority;

provided, however, that the foregoing shall not be deemed to be a waiver of any right of recourse the Company may have against the Authority, the holder of any Bond or others, including but not limited to, the rights, causes of action or claims which may arise out of the breach of their respective obligations or the inaccuracy of their respective warranties, provided, however, that the Company may pursue any such right, claim or cause of action only by a separate proceeding or action and not by counterclaim or set-off hereunder and the bringing of such separate proceeding or action shall not affect the Company's absolute, irrevocable and unconditional obligation to make payments pursuant to this Section 4.06.

Section 4.07    Assignment of Authority's Rights.

Section 7.02    Remedies on Default. In the event any of the Bonds shall at the time be Outstanding and unpaid and provision for the payment thereof shall not have been made in accordance with the provisions of the Indenture, whenever any Event of Default referred to in Section 7.01 hereof shall have happened and be subsisting, the Authority or the Trustee, following acceleration of the Bonds in accordance with provisions of Section 12.03 of the Indenture where so provided, may take any one or more of the following remedial steps:

(a)The Trustee as provided in the Indenture may, at its option, or shall, to the extent required by the Indenture, declare all payments payable under clauses (a) - (e) of Section 4.02 hereof and the Note for the remainder of the term of this Participation Agreement to be immediately due and payable, whereupon the same shall become immediately due and payable.

(b)The Authority or the Trustee may take whatever action at law or in equity that may appear necessary or desirable to collect the amounts then due and thereafter to become due, or to enforce performance and observance of any obligation, agreement or covenant of the Company under this Participation Agreement or the Note whether for specific performance of any covenant or agreement contained herein or therein or in aid of the execution of any power herein granted.

Any amounts collected pursuant to action taken under this Section 7.02 shall be paid into the Bond Fund and applied in accordance with the provisions of the Indenture.

If any such declaration of acceleration of the Bonds shall have been annulled pursuant to the terms of the Indenture and if, at any time after such declaration, but before all the Bonds shall have matured by their terms, all arrears of interest upon the Note, and interest on overdue installments of interest (to the extent enforceable under applicable law) at the rate or rates per annum specified for the Note and the principal of and premium, if any, on the Note which shall have become due and payable otherwise than by acceleration, and all other sums payable hereunder, except the principal of, and interest on, the Note which pursuant to such declaration shall have become due and payable, shall have been paid by or on behalf of the Company or

22

Exhibit 4.2.1

provision satisfactory to the Trustee shall have been made for such payment, then such acceleration of the Note shall ipso facto be deemed to be rescinded and any such Default and its consequences shall ipso facto be deemed to be annulled, but no such annulment shall extend to or affect any subsequent Default or impair or exhaust any right or remedy consequent thereon.

Section 7.03    No Remedy Exclusive. No remedy herein conferred upon or reserved to the Authority or to the Trustee is intended to be exclusive of any other available remedy or remedies, but each and every such remedy shall be cumulative and shall be in addition to every other remedy given under this Participation Agreement or now or hereafter existing at law or in equity or by statute. No delay or omission to exercise any right or power accruing upon any Default shall impair any such right or power or shall be construed to be a waiver thereof, but any such right and power may be exercised from time to time and as often as may be deemed expedient. In order to entitle the Authority or the Trustee to exercise any remedy reserved to it in this Article, it shall not be necessary to give any notice, other than such notice as may be herein expressly required. Such rights and remedies as are given the Authority hereunder shall also extend to the Trustee and the Trustee and the Holders of the Bonds issued under the Indenture shall be deemed third party beneficiaries of all covenants and agreements herein contained.

In case the Trustee (as assignee of the Authority under the Indenture) or the Authority shall have proceeded to enforce its rights under this Participation Agreement and such proceedings shall have been discontinued or abandoned for any reason or shall have been determined adversely to the Trustee or the Authority, then and in every such case, the Company, the Authority and the Trustee shall be restored respectively to their several positions and rights hereunder, and all rights, remedies and powers of the Company, the Authority and the Trustee shall continue as though no such proceeding had been taken.

The Company covenants that, in case an Event of Default shall occur with respect to any Note Payments payable under Sections 4.02(a) - (e) hereof and the Note, then, upon demand of the Trustee (as assignee of the Authority under the Indenture) the Company will pay to the Trustee the whole amount that then shall have become due and payable under said Sections, with interest (to the extent permitted by law) on said amount at the rate of interest then borne by the Bonds pursuant to the Indenture, but not exceeding the maximum rate permitted by law, until paid, and in addition thereto, such further amounts as shall be sufficient to cover the costs and expenses of collection, including reasonable compensation to the Trustee, its agents, attorneys, and counsel, and any other expenses or liabilities incurred by the Trustee other than those incurred through bad faith or negligence.

In case the Company shall fail forthwith to pay such amounts upon such demand, the Authority or the Trustee (as assignee of the Authority under the Indenture) shall be entitled and empowered to institute any action or proceeding at law or in equity for the collection of the sums so due and unpaid, and may prosecute any such action or proceeding to judgment or final decree, and may enforce any such judgment or final decree against the Company and collect, in the manner provided by law out of the property of the Company, the monies adjudged or decreed to be payable.

23

Exhibit 4.2.1

In case there shall be pending proceedings for the bankruptcy or for the reorganization of the Company under the Federal bankruptcy laws or any other applicable law, or in case a receiver or trustee shall have been appointed for the property of the Company or in the case of any other similar judicial proceedings relative to the Company or to the creditors or property of the Company, the Trustee shall be entitled and empowered, by intervention in such proceedings or otherwise, to file and provide a claim or claims for the whole amount owing and unpaid pursuant to this Participation Agreement and, in case of any judicial proceedings, to file such proofs of claim and other papers or documents as may be necessary or advisable in order to have the claims of the Holders and the Trustee allowed in such judicial proceedings relative to the Company, its creditors, or its property, and to collect and receive any monies or other property payable or deliverable on any such claims, and to distribute the same after the deduction of its charges and expenses; and any receiver, assignee or trustee in bankruptcy or reorganization is hereby authorized to make such payments to the Trustee, and to pay to the Trustee any amount due it for compensation and expenses, including reasonable counsel fees and expenses incurred by it up to the date of such distribution.

Nothing herein contained shall be construed to prevent the Authority from enforcing directly any of its rights under Sections 4.02, 4.13 and 5.08 hereof; provided that, in case the Company shall have failed to pay amounts required to be paid under Sections 4.02(f), 4.13 and 5.08 hereof which event shall have continued for a period of thirty (30) days after the date on which written notice of such failure, requiring the Company to remedy the same, shall have been given to the Company by the Authority or the Trustee, the Authority or the Trustee may take whatever action at law or in equity as may appear necessary or desirable to enforce performance or observance of any obligations or agreements of the Company under Sections 4.02(f), 4.13 and 5.08 hereof.

Section 7.04    No Additional Waiver Implied by One Waiver. In the event any agreement contained herein or in the Note should be breached by any party and thereafter waived by the other party, such waiver shall be limited to the particular breach so waived and shall not be deemed to waive any other breach hereunder.
