          (a) The Borrower hereby agrees to reimburse or pay to the Bank (to the extent not already paid) immediately and on the same Business Day on which the Bank shall be required to pay any draft presented under the Letter of Credit with respect to any Drawing a sum equal to (i) the amount paid by the Bank under the Letter of Credit and (ii) the amount of any taxes, fees, charges or other costs and expenses incurred by the Bank in connection with any payment made by the Bank under or with respect to the Letter of Credit. Notwithstanding the provisions of the immediately preceding sentence, in the event that any draw under the Letter of Credit is a Remarketing Draw, outside the control of the Borrower and such event is not an Event of Default, the Bank agrees that the Borrower will not be obliged to repay any such amounts drawn down until the earlier to occur of (i) demand upon the occurrence of an Event of Default, (ii) upon receipt of the proceeds from the resale of Bonds acquired under the Remarketing Draw or (iii) the Letter of Credit Termination Date.

          (b) Whenever an Event of Default shall have occurred under this Agreement, the Bank shall have the option to increase the rate of interest on the unpaid principal to the Default Rate, and if it does so, the Borrower agrees to pay interest on the unpaid principal at a rate per annum equal to the Default Rate.

          (c) If after the date of issuance of the Letter of Credit, any change in any law or regulation or in the interpretation thereof by any court or administrative or governmental authority charged with the administration thereof shall impose, modify or deem applicable any reserve, special deposit or similar requirement which would impose on the Bank any additional costs (i) generally upon the issuance or maintenance of so called letters of credit by the Bank, or (ii) specifically in respect of the Letter of Credit documents or the Letter of Credit, and the result of such imposition or additional costs upon either clause (i) or (ii) above shall be to increase the cost of the Bank of issuing or maintaining the Letter of Credit (which increase in cost shall be the result of the Bank’s reasonable allocation of the aggregate of such cost increases resulting from such events), then (x) the Bank shall so notify Borrower and (y) upon receipt of such notice from the Bank, accompanied by a certificate as to such increased costs, Borrower shall pay as of the effective date of such change or interpretation all additional amounts which are necessary to compensate the Bank for such increased costs incurred by the Bank.

          (d) The Borrower hereby agrees to pay to the Bank a fee of $150.00 upon each drawing under the Letter of Credit.

          (e) The Borrower shall execute and deliver to the Bank a Demand Note evidencing amounts due under paragraphs (a) or (b) above, such Demand Note to be substantially in the form of Exhibit B attached hereto, but in the absence of any such Demand Note, the obligation of the Borrower to repay amounts due thereunder shall be conclusively evidenced hereby and by the Bank’s records of disbursements and payments.

     2.05 Payments and Computations. (a) Payments received by the Bank from the Trustee pursuant to Sections 2.07(e), 5.03(c) and 14.01 of the Indenture shall be treated as payments made by the Borrower hereunder.

          (b) All sums payable by the Borrower hereunder, whether of principal, interest, fees, expense or otherwise, shall be paid in full, without any deduction or withholding whatsoever. In the event that the Borrower is compelled by law to make any such deduction or withholding, then the Borrower shall pay to the Bank such additional amount as will result in the receipt by the Bank of a net sum equal to the sum it would have received had no such deduction or withholding been required to be made. In the event such law, regulation or condition shall be revoked, rescinded, declared invalid or inapplicable or otherwise rescinded, the Bank shall forthwith refund to the Borrower any and all amounts repaid to it upon or after such rescission which are attributable to payments made by the Borrower to the Bank pursuant to this Section.

          (c) In the event any fees payable under the terms hereof are not paid on or before the date the same are due and payable, the payment of such fees shall be accompanied by interest thereon, at the Default Rate, from the date such payment becomes due until paid in full.

The Letter of Credit Fee paid to the Bank shall accrue and be payable through the end of the quarter in which the substitution is made as if no substitution had taken place.

Borrower has the option, in its sole discretion, to terminate the Letter of Credit, without penalty, by notifying the Bank and the Trustee, in writing, sixty (60) days prior to the date it wishes to terminate the Letter of Credit.

If no such confirmation is provided, Borrower may terminate the Letter of Credit without penalty.

The execution of the Borrower Documents by the Borrower does not require any consent(s) which have not otherwise been obtained, whether of the Borrower’s creditors or otherwise; and does not violate Borrower’s certificate of incorporation, by-laws or similar documents or agreements of creation, governance, or management.

The Borrower has obtained all Licenses and Permits and private approvals of every nature whatsoever, if any, as may be reasonably required to conduct or transact its business or to own, lease or operate its property, and no violations with respect thereto, except where the failure to do so, or such violations, would not have a Material Adverse Effect.

          (i) Full Disclosure. The representations and warranties made by Borrower in this Agreement do not contain any untrue statement of a material fact, and do not omit to state a material fact necessary to make the statements contained in such representations and warranties not misleading, in light of the circumstances under which they were made.

               (v) With respect to the Facilities, there are no proceedings, governmental administrative actions or judicial proceedings pending or contemplated under any federal, state or local law regulating the discharge of hazardous or toxic materials or substances into the environment, to which the Borrower is named as a party.

               (ii) The Borrower represents, warrants and covenants that the Borrower has received all of such Governmental Consents with respect to its assets, properties and operations, and (ii) all of such Governmental Consents have been duly and validly granted by the governmental authorities in the jurisdictions where its operations are located, are in full force and effect and have not been amended, modified, rescinded, revoked or assigned, except to the extent no Material Adverse Effect would in each case be caused thereby.

               (iii) To the best of the Borrower’s knowledge, no condition exists or event has occurred that, in itself or with the giving of notice or lapse of time or both, would result in the suspension, revocation, impairment, forfeiture, non-renewal of any Governmental Consent applicable to any operations owned or operated by the Borrower or the Borrower’s participation in any government programs, and there is no claim that any such Governmental Consent, participation or contract is not in full force and effect.

          (i) Transactions with Affiliates. Except in the ordinary course of and pursuant to the reasonable requirements of the Borrower’s business and upon fair and reasonable terms no less favorable to the Borrower than would obtain in a comparable arms’ length transaction with a Person not an Affiliate, Borrower shall not enter into any transaction, including, without limitation, the purchase, sale, or exchange of property or the rendering of any service, with any Affiliate.

          (j) ERISA. Borrower shall not (i) terminate any Plan so as to result in any material liability to the Borrower, or (ii) engage in or permit any Person to engage in any “Prohibited Transaction” involving any Plan which would subject the Borrower to any material tax, penalty or other liability.

          (k) Debt to Capitalization. The Borrower shall not exceed a Debt to Capitalization ratio (“Debt to Capitalization Ratio”) of 70%. Such ratio shall be measured quarterly as of the close of each fiscal quarter. “Debt” shall mean the sum of all notes payable and other short-term obligations (including current maturities of long-term debt and capital lease obligations), plus long-term debt (including capital lease obligations). “Capitalization” shall mean total capital of the Borrower.

          (l) EBIT to Interest.

        The Borrower acknowledges and agrees that each and every Event of Default described above shall be of equal weight and significance, and equally and fully shall allow Bank to exercise its rights and remedies hereunder. The Borrower acknowledges and agrees that the Bank has relied on each such Event of Default, and been induced thereby, to enter into this Agreement and that the Bank would be irreparably harmed if the Bank, in any way, were unable to exercise its rights and remedies on the basis that certain Events of Default (for example, Events of Default not relating to payment) were of less weight or significance than certain other Events of Default (for example, Events of Default relating to payment).

SECTION 7. REMEDIES.

     7.01 Notice to Trustee. Upon the occurrence of an Event of Default, the Bank shall, at its option, and in its sole discretion, have the right to notify the Trustee of the occurrence of such Event of Default and, in its sole discretion, to request that the Trustee require a redemption of the Bonds in accordance with Section 8.02 of the Indenture or require the Trustee to pursue any and all remedies available under Indenture. Upon the occurrence of any Event of Default, whether or not the Bank notifies the Trustee of such Event of Default and whether or not the Trustee draws upon the Letter of Credit to redeem the Bonds as a result thereof, (a) the Bank shall have the option to declare (i) all sums then owing to the Bank hereunder (including without limitation the Term Loan) or under any of the other Borrower Documents, plus (ii) a sum equal to the then Stated Amount of the Letter of Credit (which sum, upon receipt thereof by the Bank, shall be held by the Bank as collateral security for the reimbursement of any drawings under the Letter of Credit and the payment of any other amounts due and payable hereunder or under any of the other Borrower Documents and as collateral security for the Trustee for the benefit of the Bondholders for the repayment by the Borrower of principal and interest on the Bonds), immediately due and payable by the Borrower to the Bank, without presentment, demand, protest, or notice of any kind; provided that upon the occurrence of any Event of Default described in Section 6.01(i) the above-described sums shall automatically become immediately due and payable without the necessity of any such declaration by the Bank; (b) the Bank shall have all the rights and remedies provided herein, in the other Related Documents, at law, in equity or otherwise, including, without limitation, the right to enforce any liens granted under this Agreement, subject to the mortgage of the First Mortgage Bonds and (c) the Bank may cause the Borrower to take action to enforce the Borrower’s rights under the Related Documents.

-27-

Exhibit 4.20

     7.02 Defaults under Other Documents. The Bank shall have the right to cure any default under any of the Related Documents but shall have no obligation to do so and any action to so cure a default shall not be deemed to make the Bank liable for any other obligations of the Borrower.

SECTION 8. OTHER ACTIONS BY THE BANK

     8.01 Right to Advance or Post Funds. The Bank, in addition to its other rights granted by this Agreement or otherwise, shall have the right to advance or post funds. In the event of the occurrence of an Event of Default or Default under any of the Related Documents, the Bank may advance or transfer, as applicable, funds from any account provided hereunder to cure such default and may thereafter advance its own funds for the account of the Borrower to correct such event or condition, as the Bank deems proper, without prejudice to the Borrower’s rights, if any, to recover such funds from the party to whom paid. Such advances may be pursuant to such agreements as the Bank deems proper. All sums so advanced by the Bank from its own funds to cure any such default or to correct any such event or condition, or which are agreed to be paid pursuant to any such agreement, shall be for the account of the Borrower. Any amounts advanced by the Bank to pay such accrued amounts hereunder shall constitute Other Accrued Amounts and shall be reimbursed to the Bank. The Bank shall give notice to the Borrower of any action it takes pursuant to this Section 8, but the Bank’s failure to give notice to the Borrower of any actions permitted by this Section 8 shall not affect the Bank’s right to take any such action or the Borrower’s reimbursement obligation for any amounts advanced or paid by the Bank hereunder. Nothing in this Agreement shall be construed as imposing under any circumstances any obligation upon the Bank to cure any default of the Borrower under this Agreement or under any of the Borrower Documents or other Related Documents, or otherwise to advance any funds or perform any of the Obligations of the Borrower hereunder or thereunder.

     8.02 LIBOR Rate Lending Unlawful. If the Bank shall determine (which determination shall, upon notice thereof to the Borrower be conclusive and binding on the Borrower) that the introduction of or any change in or in the interpretation of any law, rule, regulation or guideline, (whether or not having the force of law) makes it unlawful, or any central bank or other governmental authority asserts that it is unlawful, for the Bank to make, continue or maintain any LIBOR Rate loan as a LIBOR Rate loan of a certain duration, then until the Bank shall notify the Borrower that the circumstances causing such suspension no longer exist, interest on all Drawings outstanding shall bear interest at the Bank’s Prime Rate beginning at the end of the then current Interest Periods with respect thereto or sooner, if required by such law or assertion.

     8.03 Substitute Rate. If the Bank shall have determined that: (a) US dollar deposits in the relevant amount and for the relevant Interest Period are not available to the Bank in the London interbank market; (b) by reason of circumstances affecting the Bank in the London interbank, adequate means do not exist for ascertaining the LIBOR Rate applicable hereunder to Drawing, or (c) LIBOR no longer adequately reflects the Bank’s cost of funding loans; then, upon notice from the Bank to the Borrower, then until the Bank shall notify the Borrower that the

-28-

Exhibit 4.20

circumstances causing such suspension no longer exist, interest on all Drawings outstanding shall bear interest at the Bank’s Prime Rate.

     8.04 Increased Costs. If on or after the date hereof the adoption of any applicable law, rule or regulation or guideline (whether or not having the force of law), or any change therein, or any change 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 the Bank with any request or directive (whether or not having the force of law) of any such authority, central bank or comparable agency: (a) shall subject the Bank to any tax, duty or other charge with respect to its LIBOR Rate loans or its obligation to make LIBOR Rate loans, or shall change the basis of taxation of payments to the Bank of the principal of or interest on its LIBOR Rate loans or any other amounts due under this agreement in respect of its LIBOR Rate loans or its obligation to make LIBOR Rate loans (except for the introduction of, or change in the rate of, tax on the overall net income of the Bank or franchise taxes, imposed by the jurisdiction (or any political subdivision or taxing authority thereof) under the laws of which the Bank is organized or in which the Bank’s principal executive office is located); or (b) shall impose, modify or deem applicable any reserve, special deposit or similar requirement (including, without limitation, any such requirement imposed by the Board of Governors of the Federal Reserve System of the United States) against assets of, deposits with or for the account of, or credit extended by, the Bank or shall impose on the Bank or on the London interbank market any other condition affecting its LIBOR Rate loans or its obligation to make LIBOR Rate loans; and the result of any of the foregoing is to increase the cost to the Bank of making or maintaining any LIBOR Rate loan, or to reduce the amount of any sum received or receivable by the Bank under this Agreement with respect thereto, by an amount deemed by the Bank to be material, then, (x) the Bank shall so notify Borrower and (y) upon receipt of such notice from the Bank, accompanied by a certificate as to such increased costs, Borrower shall pay as of the effective date of such change or interpretation all additional amounts which are necessary to compensate the Bank for such increased costs incurred by the Bank. The Borrower may review and comment on the Bank’s reasons for, and calculation of, the increased costs, which comments the Bank shall consider in good faith in making its final certification. However, the final certification of the Bank as to such increased costs shall be conclusive (absent manifest error) as to the amount thereof.

     8.05 Offering Statement. Within five (5) business days of the Borrower’s written request, the Bank shall either confirm or update disclosure information regarding the Bank, in the form currently contained in Appendix D of the Offering Statement of the Borrower, dated March 1, 2004.

SECTION 9. GENERAL PROVISIONS.

     9.01 Amendment and Waiver. The Borrower Documents may only be amended, terminated, extended, or otherwise modified by a writing signed by each party thereto. In no event whatsoever shall any oral agreements, promises, actions, inactions, knowledge, course of conduct, course of dealing, or the like be effective to modify, terminate, extend, or otherwise amend any Borrower Document. ANY ACTION, INACTION, ORAL STATEMENTS, COURSE OF CONDUCT OR DEALING, OR ANY OTHER NON-WRITTEN WAIVERS, MODIFICATIONS, OR AMENDMENTS TO THE BORROWER DOCUMENTS ARE

-29-

Exhibit 4.20

EXPRESSLY UNAUTHORIZED AND SO THE BANK MAY NEVER BE BOUND THEREBY. ACCORDINGLY, AS THE BORROWER IS HEREBY BEING ADVISED THAT ANY SUCH ACTIONS BY AN OFFICER, AGENT, OR EMPLOYEE ARE NOT AUTHORIZED BY THE BANK, RELIANCE THEREON SHALL BE CONSIDERED TO BE PER SE UNREASONABLE.

     9.02 Notices. All notices, requests and demands to or upon the respective parties hereto to be effective shall be in writing (which writing may be in the form of a facsimile transmission provided that a copy thereof is delivered by other permitted means), and, unless otherwise expressly provided herein, shall be deemed to have been duly given or made when delivered, or five days after being deposited in the mail, postage prepaid, or, in the case of facsimile notice, when received, addressed as follows, or to such other address as may be hereafter notified by the respective parties hereto:

provided that any notice, request or demand to or upon the Bank pursuant to Section 2 shall not be effective until received.

Exhibit 4.20

     9.03 No Waiver; Cumulative Remedies. No failure to exercise and no delay in exercising, on the part of any party hereto, any right, remedy, power or privilege hereunder or under the Borrower Documents shall operate as a waiver thereof; nor shall any single or partial exercise of any right, remedy, power or privilege hereunder preclude any other or further exercise thereof or the exercise of any other right, remedy, power or privilege. The rights, remedies, powers and privileges herein provided are cumulative and not exclusive of any rights, remedies, powers and privileges provided by law.

     9.04 Survival of Representations and Warranties. All agreements, representations and warranties made in this Agreement and the other Borrower Documents and in any related certificates shall survive the execution and delivery of this Agreement and the issuance and expiration of the Letter of Credit, and shall continue until any and all sums payable under this Agreement and all Obligations shall have been paid and performed in full.

     9.05 Payment of Expenses and Taxes; Indemnification. (a) The Borrower agrees (i) to reimburse the Bank for its reasonable out-of-pocket costs, fees and expenses paid or incurred in connection with the development, preparation, negotiation and execution of, and any amendment, supplement or modification to, the Commitment Letter, this Agreement and the other Borrower Documents and any other documents prepared in connection herewith or therewith, and the consummation and administration of the transactions contemplated hereby and thereby, including, without limitation, the reasonable fees and disbursements of counsel to the Bank or accountant’s fees and including without limitation a fee of Two Hundred Fifty Dollars ($250.00) for any amendment to the Letter of Credit, all taxes and assessments, recording fees, the letter of credit transfer fee and the fees of any third party consultants which provide services to the Bank performing services as may, from time to time, be required by the Bank, provided that attorney’s fees related to the development, preparation, negotiation and execution of the Commitment Letter, this Agreement and other documents related to the initial transaction shall not exceed $25,000, (ii) to reimburse the Bank for all its reasonable costs and expenses incurred in connection with the enforcement or preservation of any rights under this Agreement, the Related Documents and any such other documents, including, without limitation, the reasonable fees and disbursements of counsel to the Bank, (iii) to indemnify and hold the Bank harmless, from, any and all recording and filing fees and any and all liabilities with respect to, or resulting from any delay in paying, stamp, excise and other taxes, if any, which may be payable or determined to be payable in connection with the execution and delivery of, or consummation or administration of any of the transactions contemplated by, or any amendment, supplement or modification of, or any waiver or consent under or in respect of, this Agreement or the Related Documents and any such other documents with respect to such Borrower, and (iv) to indemnify and hold the Bank (and its respective affiliates, directors, officers, agents and employees (collectively, the “Indemnified Parties”) harmless from and against any and all other liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, out-of-pocket expenses or disbursements of any kind or nature whatsoever arising from or in connection with the execution, delivery, enforcement, performance and administration of this Agreement, the Related Documents and any such other documents, including but not limited to (A) any breach by Borrower of any representation, warranty or covenant made in or pursuant to this Agreement; (B) any failure by Borrower to comply with any applicable Legal Requirement or federal or state laws or regulations pertaining to the offer and sale of the Bonds; or (C) any failure by Borrower

-31-

Exhibit 4.20

to comply with any applicable Legal Requirement or the laws or regulations of any jurisdiction (all the foregoing in this clause (iv), collectively, the “Indemnified Liabilities”), provided, that such Borrower shall have no obligation hereunder to any Indemnified Party with respect to Indemnified Liabilities arising solely from such Indemnified Party’s gross negligence or willful misconduct. Nothing contained herein is intended to limit the Borrower’s obligations under Section 2.04.

          (b) Neither the Bank nor any of the officers, directors, employees or agents of the Bank shall be liable or responsible for: (i) the use made of the Letter of Credit or for any acts or omissions of the Trustee or any Letter of Credit beneficiary; (ii) the validity, sufficiency or genuineness of any documents, or endorsements, even if such documents should in fact prove to be in any or all respects invalid, insufficient, fraudulent or forged, (iii) payment by the Bank against presentation of documents which do not comply with the terms of the Letter of Credit, including failure of any documents to bear adequate reference to the Letter of Credit; or (iv) any other circumstances in making payment under the Letter of Credit in accordance with its terms provided, however, the Bank shall be liable to the extent of any direct damages suffered by the Borrower as a result of the Bank’s (y) willful misconduct or gross negligence in determining whether documents presented under the Letter of Credit comply with the terms thereof, or (z) the Bank’s willful failure to pay under the Letter of Credit after presentation to it by the Trustee of a draft and certificate complying with the terms and conditions of the Letter of Credit. The determination of whether a draft has been presented under the Letter of Credit prior to the Letter of Credit Termination Date or whether a draft drawn under the Letter of Credit or any accompanying document or instrument is in proper and sufficient form shall be made by the Bank in its sole discretion, which determination shall be conclusive and binding upon the Borrower, absent manifest error. The Borrower hereby waives any right to object to any payment made under the Letter of Credit against a draft with accompanying documents in the forms provided for in the Letter of Credit but varying in punctuation, capitalization, spelling or similar matters of form. IN NO EVENT SHALL THE BANK EVER BE LIABLE FOR CONSEQUENTIAL OR PUNITIVE DAMAGES, ANY RIGHT OR CLAIM THERETO BEING EXPRESSLY AND UNCONDITIONALLY WAIVED.

          (c) The Borrower agrees that it does not have any claims or causes of action against any disclosed or undisclosed officer, director, employee, trustee, shareholder, partner, principal, parent, subsidiary or other affiliate of Bank (collectively, the “Bank’s Affiliates”) arising out of or in connection with this Agreement or the transactions contemplated hereby. The Borrower agrees to look solely to the Bank and its assets for the satisfaction of any liability or obligation arising out of or in connection with this Agreement or the transactions contemplated hereby, and further agrees not to ▇▇▇ or otherwise seek to enforce any personal obligation against any of Bank’s Affiliates with respect to any matters arising out of or in connection with this Agreement or the transactions contemplated hereby.

          (d) Without limiting the generality of the foregoing, the Borrower hereby unconditionally and irrevocably waives any and all claims and causes of action of any nature whatsoever it may now or hereafter have against Bank’s Affiliates, and hereby unconditionally and irrevocably releases and discharges Bank’s Affiliates from any and all liability whatsoever which may now or hereafter accrue in favor of the Borrower against Bank’s Affiliates arising out

-32-

Exhibit 4.20

of or in connection with this Agreement or the transactions contemplated hereby except for the Bank’s gross negligence or willful misconduct.

          (e) The provisions of this Section 9.05 shall survive the issuance of the Letter of Credit, the performance of the Obligations of the Borrower hereunder, and the termination of this Agreement.

     9.06 Successors and Assigns; Participations. (a) This Agreement is a continuing obligation and shall be binding upon the Bank and the Borrower, and their respective successors, transferees and assigns, and shall inure to the benefit of and be enforceable by the Bank and the Borrower, and their respective successors, transferees and assigns; provided, however, that the Borrower may not assign all or any part of this Agreement without the prior written consent of the Bank, except that Borrower may assign any and all of its obligations to an entity it merges with as provided herein. This is intended to be a restriction on both the right and the power to assign, and any purported assignment not consented to by the Bank as herein required shall be void, shall confer no rights on the purported assignee and need not be recognized by the Bank.

          (b) The Bank may, without notice to or the consent of any party, sell, assign or otherwise dispose of all or any portion of its rights under the Borrower Documents to one or more parties which are banks, other than banks with no United States office or United States or state license, so long as such actions do not adversely affect any rating then borne by the Bonds or subject them to redemption or otherwise impair any of Borrower’s rights under the Bonds. In the event all of such rights, remedies, powers, privileges, and duties are transferred to another person or entity (including, without limitation, any trustee or other fiduciary) where the Bonds retain their rating as of the time of such transfer, then such party shall succeed to and become vested with all rights, remedies, powers, privileges, and duties of the Bank under the Borrower Documents and, upon written notice thereof to the Borrower, the Bank shall thereupon be discharged and relieved from its duties and obligations hereunder and thereunder. The Borrower shall accord full recognition to any such assignment, and all rights and remedies of the Bank in connection with the interest so assigned shall be as fully enforceable by such assignee as they were by the Bank before such assignment.

          (c) The Bank may, without notice to or the consent of any party sell its interest in the Letter of Credit, in whole or in part, provided Borrower’s rights under the Commitment Letter, the Borrower Documents or the documents evidencing the Bonds will not be modified thereby and provided no downgrade of the Bonds shall occur as a result thereof. Borrower hereby agrees to provide the Bank with reasonable cooperation it may require in the sale of participations in the Letter of Credit, including but not limited to, supplying financial statements and other financial information and the documentation pertaining to the issuance of the Letter of Credit. Borrower hereby gives the Bank the right to provide potential participants with any and all information pertaining to Borrower and the Letter of Credit which may be required by the participant in evaluating the purchase of a loan participation. The terms and conditions at which participations are to be sold are to be determined at the Bank’s sole discretion.

-33-

Exhibit 4.20

          (d) In connection with a sale or assignment pursuant to subsection (b) or (c) above, the Borrower hereby authorizes the Bank to disclose to any prospective or actual participants or transferees (each, a “Transferee”) any and all financial information in the Bank’s possession concerning the Borrower which has been delivered to the Bank by or on behalf of the Borrower pursuant to this Agreement or which has been delivered to the Bank by or on behalf of the Borrower in connection with the Bank’s credit evaluation of the Borrower prior to becoming a party to this Agreement, provided that the proposed transferee agrees to keep such information confidential.

     9.07 Set-Off. In any proceeding by the Bank or its Affiliates against the Borrower for a right of set-off of liabilities arising hereunder upon and against any and all instruments, documents, policies and certificates of insurance, securities, goods, accounts receivable, choses in action, chattel paper, cash, property and the proceeds thereof owned by the Borrower or in which the Borrower has an interest, which now or hereafter are at any time in possession or control of the Bank or an Affiliate or in transit by mail or carrier to or from the Bank or an Affiliate or in the possession of any third party acting in the Bank’s behalf, without regard to whether the Bank received the same in pledge, for safekeeping, as agent for collection or transmission or otherwise or whether the Bank has conditionally released the same, Borrower agrees to waive its statutory defenses and rights against said set-off.

     9.08 Power of Attorney. The Borrower hereby irrevocably constitutes and appoints the Bank, during the continuance of an Event of Default hereunder, as its true and lawful attorney-in-fact with full irrevocable power and authority in the place and stead of the Borrower to take any and all appropriate action and to execute any and all documents and instruments that may be necessary or desirable to accomplish the purposes of the Borrower Documents. The powers conferred on the Bank hereunder are solely to protect the interests of the Bank and shall not impose any duty upon the Bank to exercise any such power.

     9.09 Conflicts. This Agreement and the Letter of Credit are intended to govern the entire relationship between the parties with respect to the Letter of Credit and the terms and provisions hereof and thereof expressly supplement the other Borrower Documents as fully as if set forth therein. In the event of a conflict between the rights of the Bank under any of the Borrower Documents, then the Bank may elect, at its sole discretion, to exercise any such rights in such order and combinations as it deems appropriate. However, if after giving effect to such interpretive guidelines a conflict still exists between the terms and provisions of this Agreement and any other Borrower Document, then this Agreement shall govern.

     9.10 Severability. Any provision of this Agreement which is prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof, and any such prohibition or unenforceability in any jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction.

Exhibit 4.20

     9.11 Integration; Confidentiality. (a) This Agreement and the Borrower Documents represent the agreement of the Borrower and the Bank with respect to the subject matter hereof, and there are no promises, undertakings, representations or warranties by Bank relative to subject matter hereof, not expressly set forth or referred to in this Agreement or in the Borrower Documents.

     (b) The Borrower hereby acknowledges that the Bank and its Affiliates (collectively, the “Bank Parties”) may be providing debt financing, equity capital or other services (including financial advisory services) to other companies in respect of which the Borrower may have conflicting interests regarding the transactions described herein and otherwise. The Bank Parties will not use confidential information obtained from the Borrower by virtue of the transactions contemplated by this Agreement or their other relationships with the Borrower in connection with the performance by each of the Bank Parties of services for other companies, and each of the Bank Parties will not furnish any such information to other companies. The Borrower also acknowledges that no Bank Party has any obligation to use in connection with the transactions contemplated by this Agreement, or to furnish to it, confidential information obtained from other companies.

     9.12 No Fiduciary Relationship. The Borrower acknowledges and agrees that its dealings with the Bank are solely in the nature of a debtor/creditor relationship and that in no event shall the Bank be considered to be a partner or joint venturer of the Borrower. Borrower agrees to hold the Bank harmless from any damages and expenses resulting from the construction of the relationship of the parties as partner or joint venturer, except for any damages and expenses arising solely from the Bank’s gross negligence or willful misconduct. Also, the Borrower represents and warrants that it has independently evaluated the business transaction and has not relied upon, nor will it rely upon, the expertise, advice or other comments or statements of the Bank (including agents of the Bank), if any, in deciding to pursue such undertaking. As the Borrower is experienced in business, in no event shall the Bank owe any fiduciary or similar obligations to it in connection with the subject transaction.

     9.13 Certificate of Status. Within fifteen (15) days after the Bank’s written request, the Borrower shall provide a certificate of confirmation as to the current Obligations including, without limitation, confirmation (i) of the amounts outstanding under the Borrower Documents; (ii) if true, that no defenses, offsets, claims, or counterclaims exist to the punctual performance of all Obligations and the full payment of all amounts due under the Borrower Documents; (iii) if true, that the Borrower Documents are valid and enforceable in accordance with their terms, except as such enforceability may be limited by applicable bankruptcy, reorganization, moratorium, insolvency or other similar laws affecting the enforcement of creditors’ rights generally and except as limited by general equitable principles; (iv) if true, the Borrower Documents have not been modified or amended, either by express agreement, course of conduct, course of dealing, or otherwise; and (v) any other matter reasonably requested by the Bank.

The failure of the Borrower to timely provide such a certificate or describe in detail the basis for any disagreement shall be conclusively binding upon the Borrower

     9.17 Compliance with Usury Laws.

     Umbrella or Excess Liability

     Umbrella or excess liability coverage following the form of applicable general liability, employers’ liability and automobile liability coverages with a $5,000,000 combined single limit per occurrence, and if general aggregate limits are included, a general aggregate not less than $5,000,000 is required.

     The policy shall also provide a minimum of an amount equal $10,000,000 annual aggregate coverage or sublimits separately for the perils of earthquake and, if applicable, flood.

     Business Interruption

     Business Interruption insurance shall be secured on all operations of the Borrower covering the loss of gross earnings of the Borrower (and extra expense incurred) by reason of the total or partial suspension of, or interruption in, the use or occupancy of the operating assets of the Borrower caused by loss or damage to, or destruction of, any part of said operating assets, covering a period of suspension or interruption of a minimum of one year, in an amount not less than the maximum debt service on the Bonds due in any bond year (principal, plus interest), together with additional expenses of the Borrower expected to be incurred during such period.

     (c) Deductibles and Self-Insured Retentions. The Borrower may retain risk through deductibles and self-insured retentions on any of the commercial insurance specified in subsection (b) above, with the exception of Business Interruption Insurance, which may not be self-insured. However, deductibles or self-insured retentions shall not exceed $100,000 per occurrence for an individual contract of insurance, except as provided in subsection (d) below.

     (d) Alternative to Commercial Insurance. Except for All Risk Property, Business Interruption, and Builder’s Risk insurance, the Borrower may, with the prior written consent of the Bank, utilize alternative risk financing programs reasonably comparable to those described in subsection (b) above, including any program not rated “A-, VIII” or better by A.M. Best Co. (“Best”). Such programs may include commercial carriers with lower or no Best ratings, single-parent or group captives, risk retention groups or qualified self-insurance trusts. Any commercial insurance with deductibles or self-insured retentions exceeding $100,000 per occurrence shall be considered an alternative risk financing program and shall be subject to the provisions of this subsection.

     Should any such alternative risk financing program be used, the Borrower shall submit to the Bank documentation regarding the financial security of the program, as requested by the Bank. Such information may include, but not be limited to, actuarial certification of adequate reserves, audited financial statements, and coverage documents of the alternative risk financing program. The use of such program shall be subject to written approval by the Bank, so long as such approval is not unreasonably withheld. The right of the Bank to review and approve such programs shall in no way certify or imply that such program is financially sound, nor obligate the

Exhibit 4.20

Bank in any way to the Borrower or other third parties as to the legality or financial solvency of such programs.

     In addition to the foregoing, before the Borrower may enter into a program of self-insurance, as permitted herein, against any particular risk for which it is not on the date thereof self-insuring, it must receive a certificate from an independent insurance consultant reasonably acceptable to the Bank to the effect that an actuarially sound claims reserve fund has been created by the Borrower for such self-insurance program and is funded annually with the actuarially required deposit (as determined by an independent insurance consultant) deposited in a separate trust fund by an independent corporate trustee (which trust fund may have separate accounts).

     (e) Insurance Policy Provisions.

     (1) All insurance prescribed by this Exhibit shall be procured from sound and reputable insurers admitted to do business in the State of Connecticut, rated “A-, VIII” or better by Best or otherwise approved in writing by the Bank. Any insurers not rated “A-, VIII” or better by Best (including any such insurer approved by the Bank) shall be considered an alternative risk financing program subject to the provisions of subsection (d) above.

     (2) Should claims made form coverage be used to meet any of these risk financing requirements, the following items must be provided:

     (a) retroactive date as the first effective date of claims made coverage and prior acts or extended reporting (“tail”) coverage maintained so long as any of the obligations of the Borrower hereunder are outstanding.

     (b) an amended definition of a claim so that a claim is deemed to have been made when any insured reports an incident likely to give rise to a claim for damages under the policy.

     (c) provide the option of any extended reporting provision for a minimum of twelve months should the policy be cancelled, non-renewed or the retroactive date be advanced.

     (3) All insurance policies shall provide that the insurance company shall give at least sixty (60) days’ notice in writing to the Bank of the cancellation or non-renewal of the policy other than for non-payment of premium and at least ten (10) days’ notice in writing to the Bank, if the reason for cancellation is non-payment of premium.

     (4) All policies of insurance (except automobile, workers’ compensation, fiduciary and D&O) shall include the Bank, as an additional insured, as its interests may appear.

     (f) Evidence of Compliance; Waiver or Adjustment. Certificates of insurance and other required documentation shall be provided to the Bank prior to the delivery of the Bonds. In addition, certificates of insurance, or evidence of continuation of insurance coverage, which may be in the form of a binder, shall be provided to the Bank not less than thirty (30) days prior to the expiration of any policy period.

Exhibit 4.20

     Complete copies of insurance policies, including all declarations, terms, conditions, endorsements and exclusions shall remain available for inspection by the Bank at all reasonable times.

     The minimum limits and types of coverage stated in this Exhibit are subject to written waiver or adjustment based upon commercial availability and/or evidence of standard industry practices which may differ, from time to time, with currently stated limits. The Bank shall have the right to increase the minimum limits and modify the types of insurance required as reasonably prudent business practices dictate following, if circumstances permit, consideration or advice of an independent insurance consultant.

EXHIBIT E

     All liens in the First Mortgage listed in the “Permitted Encumbrances” section on pages 16 and 17, except subsection (f).
