(A) The Bonds, together with the premium, if any, and the interest thereon, shall be limited obligations of the Issuer payable, with respect to the Issuer, solely from the Trust Revenues, which Trust Revenues are hereby pledged and assigned for the equal and ratable payment of all sums due under the Bonds, and shall be used for no other purpose than to pay the principal of, premium, if any, on and interest on the Bonds except as may be otherwise expressly provided herein. (B)	THE BONDS ARE NOT AND SHALL NOT BE A DEBT OF THE STATE OR OF THE TOWN OF COLONIE, NEW YORK AND NEITHER THE STATE NOR THE TOWN OF COLONIE, NEW YORK SHALL BE LIABLE THEREON.

SECTION 203. EXECUTION. (A) The Bonds shall be executed on behalf of the Issuer by the manual or facsimile signature of its Chairman or its Vice Chairman, and the Issuer's corporate seal, or a reproduction thereof, shall be impressed, imprinted or otherwise reproduced thereon and attested by the manual or facsimile signature of its Secretary or its Assistant Secretary.

The reproduction of the Issuer's corporate seal on the Bonds shall have the same force and effect as if the Issuer's corporate seal had been impressed on the Bonds. (B)	In case any Authorized Representative of the Issuer whose signature shall appear on any Bond shall cease to be such Authorized Representative before the delivery of such Bond or the issuance of a new Bond following a transfer or exchange, such signature or such facsimile shall nevertheless be valid and sufficient for all purposes, the same as if such Authorized Representative had remained in office until delivery. SECTION 204. AUTHENTICATION. Only such Bonds as shall have endorsed thereon the Certificate of Authentication substantially in the forms set forth in the forms of Bond attached hereto as Exhibits A and B duly executed by the manual signature of an authorized officer of the Trustee shall be entitled to any right or benefit under this Indenture. No Bonds shall be valid or obligatory for any purpose unless and until such Certificate of Authentication shall have been duly executed by the Trustee; and such executed Certificate of Authentication upon any such Bond shall be conclusive evidence that such Bond has been authenticated and delivered under this Indenture. The Trustee's Certificate of Authentication on any Bond shall be deemed to have been executed by it if signed by an authorized officer of the Trustee, but it shall not be necessary that the same person sign the Certificate of Authentication on all of the Bonds. In the event of the appointment of a Tender Agent, other than the Trustee such Tender Agent may act as Co- Authenticating Agent with respect to the Tendered Bonds. SECTION 205. MUTILATED, LOST, STOLEN OR DESTROYED BONDS. (A) In the event any Bond is mutilated, lost, stolen or destroyed, the Issuer may execute and the Trustee may authenticate a new Bond, executed by the Issuer as provided in Section 203 hereof, of like maturity, interest rate and denomination as the Bond so mutilated, lost, stolen or destroyed. Any mutilated Bond shall first be surrendered to the Trustee; and in the case of any lost, stolen or destroyed Bond, there shall first be furnished to the Trustee evidence of such loss, theft or destruction satisfactory to the Trustee, together with indemnity satisfactory to the Trustee. The Issuer or the Trustee may charge the holder or owner of such Bond a sum sufficient to cover any tax or other governmental charge in connection with such exchange or substitution of such new Bond, together with any other reasonable fees and expenses incurred by the Issuer or the Trustee in connection therewith. (B)	Every Bond issued pursuant to the provisions of this Section 205 shall be equally and proportionately entitled to the benefits of this Indenture with all other Bonds secured by the Indenture. However, the Trustee shall not be required to treat both the original Bond and any Bond issued in lieu thereof as being Outstanding for purposes of determining the principal amount of Bonds Outstanding under this Indenture or for the purpose of determining any percentage of Bonds Outstanding hereunder, but both the original Bond and the Bond issued in lieu thereof shall be treated as one and the same. (C)	Notwithstanding any other provision of this Section 205, in lieu of delivering a new Bond for a Bond which has been mutilated, lost, stolen or destroyed and which has matured, upon receipt of evidence of such mutilation, loss, theft or destruction and indemnity satisfactory to the Trustee, the Trustee may make payment for such Bond. SECTION 206. TRANSFER AND EXCHANGE OF BONDS; PERSONS TREATED AS OWNERS. (A) The Trustee is designated and agrees to act as Bond Registrar and shall cause a bond register to be kept on behalf of the Issuer at the Office of the Trustee for the registration and transfer of Bonds. Except as provided in Section 213 hereof, any Bond, upon the surrender of such Bond to the Bond Registrar, may be transferred, but only upon delivery of an assignment duly executed by the registered owner or his duly authorized legal representative in the form imprinted on the Bond or in such other form as shall be satisfactory to the Bond Registrar. (B)	Except as otherwise provided in Section 206(E) or Section 213 hereof, upon receipt of such Bond and upon satisfaction of the conditions set forth in Section 206(A) and Section 206(C) hereof, the Trustee shall immediately record the transfer of such bond on the bond register and cause the transferee or transferees to be the registered owner of such Bond. Upon any such registration of transfer, the Issuer shall execute and the Trustee shall authenticate and deliver in exchange for such Bond one or more new Bonds, executed by the Issuer as provided in Section 203 hereof, registered in the name of the designated transferee thereof, of any denomination or denominations authorized by this Indenture and for the same aggregate principal amount as the Bond or Bonds surrendered for transfer. (C)	In the event of the appointment of a Tender Agent, other than the Trustee, such Tender Agent may act as Co-Bond Registrar with respect to Tendered Bonds. (D)	No service charge shall be made for any transfer or exchange of Bonds, but in all cases in which Bonds shall be transferred or exchanged hereunder, the Issuer or the Trustee may make a charge for every transfer or exchange of Bonds sufficient to reimburse them for any tax, fee or other governmental charge required to be paid with respect to such transfer or exchange, and such charge shall be paid before any such new Bond shall be delivered. (E)	The Person in whose name any Bond shall be registered shall be deemed and regarded as the absolute Owner thereof for all purposes, and payment of or on account of the principal of, or the premium if any or interest on, any such Bond shall be made only to or upon the order of the registered Holder thereof or his duly authorized legal representative, subject to the terms of Section 207(C) hereof. Such registration may be changed only as provided in this Section 206, and no other notice to the Issuer or the Trustee shall affect the rights or obligations with respect to the transference of any Bond or be effective to transfer any Bond. All payments to the Person in whose name any Bond shall be registered shall be valid and effectual to satisfy and discharge the liability upon such Bond to the extent of the sum or sums so paid. (F)	The Trustee shall not be required to make any such transfer or exchange of (1) any Bond during the fifteen (15) days next preceding a Bond Payment Date or (2) any Bond selected for redemption in whole or in part under Article III hereof; provided, however, that in the event of a Bond selected for redemption in part, nothing in this paragraph shall prohibit exchange of the remaining portion of such Bond redeemed in part for a new Bond with a reduced principal amount or the transfer or exchange of any such new Bond; provided, further that the foregoing shall not apply to the registration or transfer of any Bond which has been tendered to the Tender Agent pursuant to Section 304 hereof, and in any such case, for purposes of selection for redemption, the Bond so tendered and the Bond issued to the transferee thereof shall be deemed and treated as the same Bond. SECTION 207. PAYMENT PROVISIONS. (A) Payment of the principal of, premium, if any, on and interest on the Bonds shall be made in lawful money of the United States of America. (B)	Interest and any Sinking Fund Payment or principal payment due prior to maturity on any Bond which is payable, and which is punctually paid or duly provided for, on any Bond Payment Date shall be paid to the Person appearing on the bond register as the registered owner of that Bond (or one or more Predecessor Bonds) at the close of business on the Regular Record Date, by check or draft of the Trustee mailed by the Trustee on such Bond Payment Date to such registered owner at his address as it appears on the bond register; provided that at the option of any Holder of Bonds in an aggregate principal amount of $250,000 or greater, the Trustee shall cause such amounts to be transmitted on such Interest Payment Date by wire transfer at such owner's written request to the bank account number on file with the Trustee, provided such owner has delivered adequate instructions regarding same to the Trustee at least ten (10) Business Days prior to such Bond Payment Date. (C)	Any interest and any Sinking Fund Payment or principal payment due prior to maturity on any Bond which is payable, but is not punctually paid or duly provided for, on any Bond Payment Date (herein called "Defaulted Payments") shall forthwith cease to be payable to the Person appearing on the bond register as the registered owner on the relevant Regular Record Date solely by virtue of such Person having been such registered owner; and the Trustee shall make payment of any Defaulted Payments on Bonds to the Persons in whose names such Bonds (or their respective Predecessor Bonds) are registered at the close of business on a Special Record Date for the payment of such Defaulted Payments, which shall be fixed in the following manner. The Trustee shall determine the amount of Defaulted Payments to be paid on each Bond and establish the date of the proposed payment (which date shall be such as will enable the Trustee to comply with the next sentence hereof), and money in the aggregate amount of the proposed Defaulted Payments shall be segregated by the Trustee to be held in trust for the benefit of the Persons entitled to such Defaulted Payments as in this Subsection provided and not to be deemed part of the Trust Revenues. Thereupon the Trustee shall fix a Special Record Date for the payment of such Defaulted Payments which shall be not more than fifteen (15) nor less than ten (10) days prior to the date of the proposed payment. The Trustee shall promptly notify the Issuer, the Bank and the Company of such Special Record Date and shall cause notice of the proposed payment of such Defaulted Payments and the Special Record Date therefor to be mailed one time, first-class postage prepaid, to each registered owner of a Bond at his address as it appears in the bond register not less than ten (10) days prior to such Special Record Date. Notice of the proposed payment of such Defaulted Payments and the Special Record Date therefor having been mailed as aforesaid, such Defaulted Payments shall be paid to the Persons in whose names the Bonds (or their respective Predecessor Bonds) are registered on such Special Record Date. (D)	Subject to the foregoing provisions of this Section, each Bond delivered under this Indenture upon transfer of or in exchange for or in lieu of any other Bond shall carry all the rights to interest and any Sinking Fund Payments or principal payments due prior to maturity accrued and unpaid, and to accrue, which were carried by such other Bond, and each such Bond shall bear interest from such date so that neither gain nor loss in interest shall result from such transfer, exchange or substitution. (E)	The principal of and premium, if any, on any Bonds due at maturity shall be payable at the Office of the Trustee, upon presentation and surrender of such Bond by the registered owner thereof or his duly authorized legal representative at the maturity of such Bond or such other date as such payments become due, by redemption or otherwise. Except as provided in subsection (B) hereof, in the event of a partial redemption of any Bond, payment of the redemption price shall be made to the registered owner or his duly authorized legal representative only upon surrender to the Trustee of such Bond, and upon such surrender the Trustee shall authenticate a new Bond executed by the Issuer as provided in Section 203 for the unredeemed portion of such Bond. (F)	In NO EVENT shall the Trustee pay any portion of the principal of, premium, if any, or interest on any Bond from other than Non-Preference Moneys. SECTION 208. TEMPORARY BONDS. (A) Until definitive Bonds are ready for delivery, there may be executed, and upon the request of the Issuer the Trustee shall authenticate and deliver in lieu of definitive Bonds, temporary printed, lithographed or typewritten Bonds, in any authorized denomination, in substantially the tenor set forth in Exhibits A and B attached hereto and with such appropriate omissions, insertions and variations as may be required. (B)	If the Bonds are no longer Book Entry Bonds and if temporary Bonds shall have been issued, the Issuer shall, at the sole cost and expense of the Company, cause the definitive Bonds to be prepared and to be executed and delivered to the Trustee, and the Trustee, upon presentation to it at the Office of the Trustee of any temporary Bond, shall cancel the same and authenticate and deliver in exchange therefor, without charge to the owner thereof, a definitive Bond or Bonds of an equal aggregate principal amount of the same maturity and bearing interest at the same rate as the temporary Bond surrendered. Until so exchanged, the temporary Bonds shall in all respects be entitled to the same benefit and security of this Indenture as the definitive Bonds to be issued and authenticated hereunder. SECTION 209. SPECIFIC DETAILS OF BONDS. (A) The Bonds shall be issued in the aggregate principal amount of $6,000,000, shall be designated "Town of Colonie Industrial Development Agency Taxable Industrial Development Revenue Bonds (Mechanical Technology Incorporated Project - Letter of Credit Secured), Series 1998A". The Bonds shall be numbered from one upward and prefixed "R". The Bonds shall be issued in the denomination of $100,000 or any integral multiple of $5,000 in excess thereof. Interest on the Bonds prior to the Conversion Date shall be payable on the first (1st) Thursday of each month, commencing January 7, 1999. (B)	(1)	The Bonds shall be dated the Closing Date and shall bear interest from the Closing Date, or from the most recent Interest Payment Date to which interest has been paid. The Bonds shall mature on December 1, 2013. (2)	The Bonds shall bear interest as follows: (a)	From the Closing Date through and including December 23, 1998, the Bonds shall bear interest at a rate per annum equal to five and fifty-five hundredths percent (5.55%). (b)	Thereafter, except as provided in (e) below, the Bonds (other than Pledged Bonds) shall bear interest at the "Adjustable Rate". (i)	The Adjustable Rate shall be the rate of interest established by the Remarketing Agent on the first Business Day prior to each Adjustment Date, which in the Remarketing Agent's reasonable judgment would result, as nearly as practicable, in the market value of the Bonds on an Adjustment Date being equal to one hundred percent (100%) of the principal amount thereof. The Adjustable Rate so determined shall be adjusted in accordance with the directions of the Remarketing Agent on the Adjustment Date and shall remain in effect through and including the day prior to the next following Adjustment Date. (ii)	In determining the Adjustable Rate pursuant to the foregoing Section 209(B)(2)(b)(i), the Remarketing Agent shall take into account, to the extent applicable, (A) the market interest rates for comparable securities held by open-end municipal or other fixed income bond funds or other institutional or private investors with substantial portfolios (w) with interest rate adjustment periods and demand purchase options substantially identical to the Bonds, (x) bearing interest at a variable rate intended to maintain par value, (y) rated by a national credit rating agency in the same category as the Bonds or, if not rated, secured by substantially the same level of security as the Bonds, and (z) the interest on which is included in gross income of the holders thereof for federal income taxation purposes; (B) other financial market rates and indices which may have a bearing on the Adjustable Rate (including, but not limited to rates borne by commercial paper, Treasury bills, commercial bank prime rates, certificate of deposit rates, federal funds rates, the London Interbank Offered Rate, indices maintained by The Bond Buyer, and other publicly available taxable interest rate indices); (C) general financial market conditions (including current forward supply); (D) factors particular to the Project or the credit standing of the Company and the Bank; and (E) such other factors which the Remarketing Agent deems appropriate. (iii)	On the Business Day prior to each Adjustment Date, the Remarketing Agent shall notify the Trustee, by Immediate Notice, of the Adjustable Rate. (c)	If for any reason the position of Remarketing Agent is vacant or the Remarketing Agent fails to act, the Adjustable Rate shall be determined by a third party selected by the Company at the Company expense and shall be equal to one hundred percent (100%) of the yield applicable to 13-week United States Treasury bills determined by such third party on the basis of the average per annum discount rate at which such 13- week Treasury bills shall have been sold (1) at the most recent Treasury auction conducted during the immediately preceding Adjustment Period, (2) if no such auction shall have been conducted during the immediately preceding Adjustment Period, at the most recent Treasury auction conducted prior to such preceding Adjustment Period, plus fifty (50) basis points; provided, however, that in the event the Company notifies the Trustee that an index (as published in The Wall Street Journal) of seven-day yield evaluations at par of issuers of securities, the interest on which is includable in gross income for federal income tax purposes, and of comparable rating to the rating on the Bonds, published by any nationally recognized municipal securities evaluation service is available, the Adjustable Rate shall be determined by the Trustee and shall be equal to such index. (d)	The Adjustable Rate shall be calculated based on a 365 or 366- day year for the actual number of days elapsed. Further, each determination of the Adjustable Rate pursuant to and in accordance with the foregoing terms of the Indenture and the terms of the Bonds shall be conclusive and binding on the Issuer, the Trustee, the Company, the Bank, and the holders of the Bonds. (e)	(i) From and after the Conversion Date through the maturity or earlier redemption of the Bonds, the Bonds shall bear interest at the Fixed Rate, which shall be a fixed rate (or rates) of interest established by the Remarketing Agent at least fifteen (15), but not more than thirty (30) days prior to the Conversion Date, which in the reasonable judgment of the Remarketing Agent would result, as nearly as practicable, in the market value of the Bonds on the Conversion Date being equal to one hundred percent (100%) of the principal amount thereof. (ii)	(A)	At the Remarketing Agent's discretion, after the exercise of the Conversion Option, the Bonds may be converted into serial bonds, with a principal amount of Bonds maturing on a Principal Payment Date each year equal to the principal amount required to be redeemed as set forth in Section 301(E) hereof. In such event, each maturity of Bonds may bear a different interest rate, each of which shall be determined by the Remarketing Agent in the same manner as the Fixed Rate (for convenience each such rate shall be referred to as the Fixed Rate); provided, however, that in no event shall the Remarketing Agent be permitted to convert the Bonds into serial bonds as described above without delivering to the Trustee an opinion of Bond Counsel that such conversion is lawful under the Act and permitted under the Indenture. (B)	The Interest Payment Dates after the exercise of the Conversion Option shall be semi-annual, with one Interest Payment Date being the first day of the month preceding the Fixed Rate Conversion Date and the other Interest Payment Date being the first day of the month six (6) months later. Principal shall be payable annually thereafter in the amounts and the years set forth in Section 301(E) hereof on the Principal Payment Dates. (iii)	In determining the Fixed Rate, the Remarketing Agent shall take into account, to the extent applicable, (A) market interest rates for comparable securities which are held by open-end municipal or other fixed income bond funds or other institutional or private investors with substantial portfolios (w) with a term equal to the period to maturity remaining on the Bonds, (x) the interest on which is includable in the gross income of the holders thereof for federal income tax purposes, (y) rated by a national credit rating agency in the same rating category as the Bonds, or, if not rated, secured by substantially the same level of security as the Bonds, and (z) with redemption provisions similar to those which have bearing on the Fixed Rate; (B) other financial market rates and indices (including but not limited to rates borne by taxable industrial development bonds, other taxable revenue bonds, Treasury obligations, commercial bank prime rates, certificate of deposit rates, federal funds rates, indices maintained by The Bond Buyer and other publicly available taxable interest rates and indices); (C) general financial market conditions (including current forward supply); (D) factors particular to the Project or the credit standing of the Company and the Bank; and (E) such other factors which the Remarketing Agent deems appropriate. (iv)	The Fixed Rate shall be calculated based on a 360-day year of twelve 30-day months. The determination of the Fixed Rate by the Remarketing Agent pursuant to and in accordance with the terms of the Indenture and the terms of the Bonds shall be conclusive and binding on the Issuer, the Trustee, the Company, the Bank and the Holders of the Bonds. (v)	To exercise the Conversion Option, the Company shall deliver at least sixty (60) days prior to the Conversion Date, written notice to the Trustee, the Issuer and the Bank of its election of the Conversion Option. On the Conversion Date, the Bonds shall be subject to a Mandatory Tender for purchase as provided in Section 304 of the Indenture. Notwithstanding anything to the contrary contained herein, such notice shall not be effective unless the Bank shall have consented thereto in writing and such notice is accompanied by: (A)	a Substitute Letter of Credit with an expiration date of not earlier than fifteen (15) days following the Principal Payment Date which is at least three (3) years after the next succeeding Principal Payment Date and in an amount equal to the sum of the aggregate principal amount of the Bonds then Outstanding, 210 days' interest thereon computed at the Fixed Rate, together with the Optional Redemption Premium; provided, however, that if the Letter of Credit then in place has an expiration date of not earlier than fifteen (15) days following the Principal Payment Date which is at least three (3) years after the next succeeding Principal Payment Date and in an amount equal to the aggregate principal amount of the Bonds then Outstanding, 210 days' interest thereon computed at the Fixed Rate, together with the Optional Premium, no Substitute Letter of Credit need be obtained; (B)	a statement as to whether the Bonds shall be serial bonds as set forth in Section 209(B)(2)(e)(ii) above; and (C)	an opinion of Bond Counsel reasonably satisfactory to the Trustee, the Issuer and the Bank to the effect that the exercise of the Conversion Option is lawful under the Act and permitted by the Indenture. (f)	Notwithstanding anything herein to the contrary, any Pledged Bond shall bear interest at a rate equal to the Bank Rate, as such rate shall change from time to time; provided, however, that at no time shall the interest rate in effect for any Pledged Bond exceed the maximum rate permitted by applicable usury laws. (g)	Notwithstanding anything herein to the contrary, in no event will the rate of interest borne by any Bond (except any Bond constituting a Pledged Bond) exceed fifteen percent (15%) per annum. (h)	The Issuer hereby appoints the Company to act as agent of the Issuer for purposes of exercising the Conversion Option, all as set forth in this Indenture, and subject to compliance with the terms and provisions of this Indenture. SECTION 210. DELIVERY OF THE BONDS. Upon the execution and delivery of this Indenture, the Issuer shall execute and deliver the Bonds (including a number of additional Bonds to be retained by the Trustee for authentication and delivery upon transfer or exchange of any Bond) to the Trustee, and the Trustee shall authenticate and deliver the Bonds to the purchasers thereof against payment of the purchase price therefor, plus accrued interest to the day preceding the date of delivery, upon receipt by the Trustee of the following: (A)	a certified copy of the Resolution; (B)	the executed original Letter of Credit; (C)	executed counterparts of the Indenture and the other Financing Documents; (D)	a request and authorization to the Trustee on behalf of the Issuer signed by an Authorized Representative of the Issuer to deliver the Bonds to the purchasers thereof upon payment to the Trustee for the account of the Issuer of the purchase price therefor; (E)	signed copies of the opinions of counsel to the Issuer, the Company and the Bank, and of Bond Counsel, as required by the Bond Purchase Agreement; (F)	the certificates and policies, if available, of the insurance required by the Installment Sale Agreement; (G)	a current survey of the Land certified to the Issuer and the Trustee; (H)	proof of compliance with the State Environmental Quality Review Act; (I)	evidence that the Project Facility is not an area of special flood hazards, or a certificate and a policy, if available, of the insurance required by Section 6.3(D) of the Installment Sale Agreement; and (J)	such other documents as the Trustee, the Bank or Bond Counsel may reasonably require. SECTION 211. CANCELLATION OF BONDS. All Bonds surrendered to the Trustee for payment, redemption, transfer or exchange shall be promptly cancelled by the Trustee. No Bond shall be authenticated in lieu of or in exchange for any Bond cancelled as provided in this Section 211, except as expressly provided by this Indenture. All Bonds cancelled by the Trustee shall be destroyed by the Trustee and shall not be reissued. At the request of the Company, certificates of destruction evidencing such destruction shall be furnished by the Trustee to the Issuer and the Company. SECTION 212. PAYMENTS DUE ON SATURDAYS, SUNDAYS AND HOLIDAYS. In any case where the date of maturity of interest or a Sinking Fund Payment on or the principal of any Bond or the date fixed for redemption of any Bond shall not be a Business Day, then payment of interest on or principal or Redemption Price of such Bond shall be made on the next succeeding Business Day with the same force and effect as if made on the date of maturity or the date fixed for redemption, and no interest shall accrue for the period after such date. SECTION 213. BOOK ENTRY BONDS. (A) Notwithstanding any other provision of this Indenture, the Bonds are hereby authorized to be issued in book entry form as Book Entry Bonds, with respect to which the following procedures shall apply. (B)	For all purposes of this Indenture, the Depository shall be deemed to be holder of a Book Entry Bond and neither the Issuer, nor the Trustee shall have any responsibility or obligation to the beneficial owner of such Bond or to any direct or indirect participant in such Depository. Without limiting the generality of the foregoing, neither the Issuer nor the Trustee shall have any responsibility or obligation to any such participant or to the beneficial owner of a Book Entry Bond with respect to (1) the accuracy of the records of the Depository or any participant with respect to any beneficial ownership interest in such Book Entry Bond, (2) the delivery to any participant of the Depository, the beneficial owner of such Book Entry Bond or any other person, other than the Depository, of any notice with respect to such Book Entry Bond, including any notice of the redemption thereof, (3) the payment to any participant of the Depository, the beneficial owner of such obligation or any other person, other than the Depository, of any amount with respect to the principal or Redemption Price of, or interest or Sinking Fund Payments on, such Book Entry Bond or (4) any consent given or any other action taken by the Depository as Holder of the Book Entry Bonds. (C)	The Issuer and the Trustee may treat the Depository of a Book Entry Bond as the absolute owner of such Book Entry Bond for purpose of (1) payment of the principal of, premium, if any, and interest on such Book Entry Bond, (2) giving notices of redemption and of other matters with respect to such Book Entry Bond, (3) registering transfers with respect to such Book Entry Bond, and (4) for all other purposes whatsoever. The Trustee shall pay all principal of, premium, if any, and interest and Sinking Fund Payments on, such Book Entry Bond only to or upon the order of the Depository, and all such payments shall be valid and effective to fully satisfy and discharge the Book Entry Bonds with respect to such principal of, premium, if any, Sinking Fund Payments and interest to the extent of the sum or sums so paid. No person other than the Depository shall receive a Book Entry Bond or other instrument evidencing the Issuer's obligation to make payments of the principal of, premium, if any, Sinking Fund Payments and interest thereon. (D)	The Issuer, in its sole discretion, upon thirty (30) days prior written notice to the Trustee and without the consent of the Trustee or the beneficial owner of a Book Entry Bond or any other person, may terminate the services of the Depository with respect to a Book Entry Bond if the Issuer determines that (1) the Depository is unable to discharge its responsibilities with respect to such Book Entry Bond or (2) a continuation of the requirement that all of the Outstanding Bonds issued in book entry form be registered in the registration books of the Issuer in the name of the Depository, is not in the best interest of the beneficial owners of such Bonds, and the Issuer shall terminate the services of the Depository upon receipt by the Issuer and the Trustee of written notice from the Depository that it has received written requests that such Depository be removed from its participants having beneficial interests, as shown in the records of the Depository, in an aggregate amount of not less than fifty percent in principal amount of the then Outstanding Book Entry Bonds. (E)	Upon the termination of the services of a Depository with respect to a Book Entry Bond, or upon the resignation of a Depository with respect to a Book Entry Bond, after which no substitute securities depository willing to undertake the functions of such Depository can be found which, in the opinion of the Issuer, is able to undertake such functions upon reasonable and customary terms, such Bonds shall no longer be registered in the registration books kept by the Trustee in the name of a Depository, but may be registered in the name of the beneficial owners of such Bonds, and such beneficial owners, upon registration of such Bonds in their names, shall become the holders of such Bonds. (F)	Notwithstanding any other provisions of the Indenture, the Trustee shall have no liability for any inconsistency, if any, between a letter of representations that may be executed and delivered by the Issuer and/or the Trustee with the Depository and the provisions hereof, and with respect to any such inconsistency, the provisions of such letter of representations shall control. SECTION 214. ADDITIONAL BONDS.

(2)	a written opinion of counsel to the Bank which shall state that the execution and delivery of such Substitute Letter of Credit by the Bank has been duly authorized, executed and delivered by the Bank and that the Letter of Credit, as amended, constitutes the legal, valid and binding obligation of the Bank enforceable against the Bank in accordance with its terms, subject to the standard exceptions with respect to bankruptcy laws, equitable remedies and specific performance; (3)	evidence that the Financing Documents, as amended or supplemented in connection with the issuance of the Additional Bonds, provide that (a) the Bonds referred to therein shall mean and include the Additional Bonds being issued as well as the Bonds originally issued under the Indenture and any Additional Bonds theretofore issued, and (b) the Project Facility referred to in the Financing Documents includes any Additional Facilities being financed;

(8)	an opinion of Bond Counsel stating that, in the opinion of such Bond Counsel, the Issuer is duly authorized and entitled to issue such Additional Bonds and that, upon the execution, authentication and delivery thereof, such Additional Bonds will be duly and validly issued and will constitute valid and binding special obligations of the Issuer, subject to the standard exceptions with respect to bankruptcy laws, equitable remedies and specific performance; and that the issuance of the Additional Bonds will not, in and of itself, adversely affect the validity of the Bonds originally issued under the Indenture or any Additional Bonds theretofore issued; (9)	written evidence from each rating agency, if any, by which the Bonds are then rated to the effect that the issuance of such Additional Bonds will not, by itself, result in a reduction of the rating(s) on the Outstanding Bonds applicable immediately prior to the issuance of the Additional Bonds;

ARTICLE III REDEMPTION OF BONDS PRIOR TO MATURITY SECTION 301. REDEMPTION OF BONDS PRIOR TO MATURITY. (A) The Bonds are subject to redemption prior to maturity (1) as a whole, without premium, as provided in Section 406 hereof, in the event of (a) a taking in Condemnation of, or failure of title to, all or substantially all of the Project Facility, (b) damage to or destruction of part or all of the Project Facility and election by the Company to redeem the Bonds in accordance with Section 7.1 of the Installment Sale Agreement, or (c) a taking in Condemnation of part of the Project Facility and election by the Company to redeem the Bonds in accordance with Section 7.2 of the Installment Sale Agreement, or (2) in part, without premium, (a) as provided in Section 406(G) hereof, in the event that (i) to the extent excess moneys remain in the Insurance and Condemnation Fund following damage or condemnation of a portion of the Project Facility and completion of the repair, rebuilding or restoration of the Project Facility by the Company, and (ii) such moneys are not paid to the Company pursuant to Section 406(G) hereof, or (b) as provided in Section 403 hereof, in the event that excess moneys remain in the Project Fund after the Completion Date. In any such event, the Bonds shall be redeemed, as a whole or in part, as the case may be, in the manner provided in this Article III, at such time as the Trustee determines, at a redemption price equal to the principal amount thereof, plus accrued interest to the redemption date, without premium. (B)	The Bonds are also subject to redemption prior to maturity in the event of failure by the Company to provide a Substitute Letter of Credit at least forty-five (45) days prior to the Interest Payment Date immediately preceding the expiration date of the Letter of Credit then in effect. In any such event, the Bonds shall be redeemed, as a whole, on such Interest Payment Date at a redemption price equal to the principal amount to be redeemed, plus accrued interest to the redemption date, without premium. (C)	The Bonds are also subject to redemption prior to maturity upon receipt by the Trustee of a written notice from the Bank of the occurrence and continuance of a default by the Company under the Reimbursement Agreement and the Bank's election to compel redemption of the Bonds. In either such event, the Bonds shall be redeemed, as a whole, in the manner provided in this Article III, on the earliest date for which the Trustee can give notice of redemption pursuant to Section 303 hereof, at a redemption price equal to the principal amount thereof, plus accrued interest to the redemption date, without premium. (D)	(1) On or prior to the Conversion Date, the Bonds are also subject to redemption prior to maturity in denominations of $5,000 or any integral multiple of $5,000 in excess thereof at the option of the Company by exercise of its right to prepay the installment purchase payments payable under the Installment Sale Agreement as provided in Section 5.5 of the Installment Sale Agreement, on any Interest Payment Date, in the manner provided in this Article III, at a redemption price equal to the principal amount thereof, plus accrued interest to the redemption date, without premium. (2)	After the Conversion Date, the Bonds are subject to redemption, at the option of the Company by exercise of its right to prepay the installment purchase payments under the Installment Sale Agreement as provided in Section 5.5 thereof, as a whole or in part on any Interest Payment Date occurring after the end of the applicable call protection period at the redemption prices, expressed as percentages of unpaid principal amount to be redeemed, plus accrued interest to the redemption date, determined as follows: the call protection period and redemption prices shall be determined by the Remarketing Agent, after taking into account the factors described in Section 209(B)(2)(e) hereof and such other factors which the Remarketing Agent deems appropriate. The determination of the call protection period and redemption prices by the Remarketing Agent pursuant to and in accordance with the terms of the Indenture shall be conclusive and binding on the Issuer, the Trustee, the Company, the Bank and the Holders of the Bonds. (E) The Bonds will also be subject to scheduled mandatory redemption, by lot in such manner as the Trustee shall deem fair and appropriate for random selection, prior to maturity, commencing December 1, 1999 and on each December 1 thereafter, by the application of Sinking Fund Payments at a redemption price equal to one hundred percent (100%) the principal amount thereof, plus accrued interest to the redemption date, without premium, on December 1 of the years and in the principal amounts set forth below: YEAR	SINKING FUND PAYMENT YEAR	SINKING FUND PAYMENT 1999	$285,000			2006	$385,000 2000	$275,000			2007 $410,000 2001	$290,000			2008	$435,000 2002	$310,000			2009 $460,000 2003	$325,000			2010	$485,000 2004	$345,000			2011 $515,000 2005	$365,000			2012	$540,000 Following retirement by mandatory sinking fund redemption prior to their Stated Maturity, there will remain $575,000 principal amount of the Bonds maturing on December 1, 2013 to be paid at maturity. (F)	In no event shall the Trustee, in connection with any redemption of Bonds under this Section 301, pay any portion of the principal of, premium, if any, or interest on any Bond from other than Non-Preference Moneys. Furthermore, the Trustee shall make such payments by first drawing on the Letter of Credit pursuant to Section 408 hereof. (G)	In the event of any partial redemption, the particular Bonds or portions thereof to be redeemed shall be selected by the Trustee not more than sixty (60) days prior to the redemption date by lot. The Trustee shall apply any partial redemption payments (other than a scheduled mandatory redemption) to the schedule of mandatory redemption in inverse order of maturity. After the Conversion Date, if the Bonds are serial bonds as provided in Section 209(B)(2)(e)(ii) hereof, the Bonds shall be redeemed in inverse order of maturity selected by lot. Further, the Trustee may provide for the selection for redemption of portions (equal to $5,000 or any whole multiple thereof) of Bonds of a denomination larger than $5,000. In no event shall the principal amount of Bonds subject to any partial redemption be other than a whole multiple of $5,000; provided, however, that no $5,000 portion of a Bond shall be redeemed if it results in the unredeemed portion of the Bond being less than $100,000. SECTION 302. COMPANY'S ELECTION TO REDEEM. (A) The Company shall give written notice to the Trustee, the Bank and the Issuer of its election to cause redemption of Bonds prior to maturity pursuant to subsections (A) and (D) of Section 301 hereof and of the redemption date. (B)	In the event of an election by the Company to redeem the Bonds pursuant to Section 301(D) hereof, such notice shall be given at the time the Company delivers to the Trustee either (1) the prepayment of installment purchase payments with which the Bonds are to be redeemed, or (2) the assurance from the Bank that the Letter of Credit may be drawn upon to pay the redemption price of the Bonds, described in Section 5.5 of the Installment Sale Agreement, and the redemption date specified in such notice shall be deemed to be (notwithstanding the actual date set forth therein) the first Interest Payment Date more than thirty (30) days after such payment or assurance, as the case may be, is received by the Trustee and on which any moneys delivered to the Trustee by the Company for such purpose shall be Non-Preference Moneys. SECTION 303. NOTICE OF REDEMPTION; PAYMENT OF REDEEMED BONDS. (A) Notice of the intended redemption of each Bond subject to redemption shall be given by the Trustee one time by first class mail postage prepaid to the registered Owner of such Bond at the address of such Owner shown on the Trustee's bond register and to the Bank at its address set forth of in Section 1103 hereof. All such redemption notices shall be given not less than thirty (30) days prior nor more than forty-five (45) days prior to the date fixed for redemption. A follow-up notice shall be given by the Trustee by registered or certified mail to each registered owner who has not submitted a Bond subject to redemption within ninety (90) to one hundred twenty (120) days following the redemption date. Each notice shall specify the redemption price, the principal amount of the Bonds to be redeemed, the numbers of the Bonds to be redeemed if less than all of the Bonds are to be redeemed, the redemption date and the place or places where amounts due upon such redemption will be payable. Such notice shall further state that payment of the applicable redemption price plus accrued interest to the redemption date will be made upon presentation and surrender of the Bonds or portions thereof to be redeemed; that upon presentation and surrender to the Trustee of any Bond being redeemed in part, a new Bond in the principal amount of the unredeemed portion of such Bond will be issued; and that the Bonds or portions thereof so called for redemption will be deemed redeemed and will cease to bear interest on the specified redemption date, provided Non-Preference Moneys for their redemption have been duly deposited in the Bond Fund and, except for the purpose of payment, that such Bonds will no longer be protected by this Indenture. The failure to give any such notice, or any defect therein, shall not affect the validity of any proceeding for the redemption of any Bond with respect to which no such failure to give notice, or defect therein, has occurred. Notwithstanding anything herein to the contrary, the Trustee shall not give any notice under this Section 303 in the case of an optional redemption pursuant to Section 301(D) hereof requiring the payment of a premium upon such redemption unless the Company shall have complied with the provisions of Section 302(B) hereof. (B)	After notice shall have been given in the manner provided in Subsection (A) above, the Bonds or portions thereof called for redemption shall become due and payable on the redemption date so designated. Upon presentation and surrender of such Bonds at the Office of the Trustee, such Bonds shall be paid at the Redemption Price, plus accrued interest to the redemption date. If there shall be selected for redemption less than all of a Bond, the Issuer shall, upon the surrender of such Bond and with no charge to the Owner thereof, (1) pay the Redemption Price of the principal amount called for redemption, and (2) cause the Trustee to authenticate and deliver for the unredeemed balance of the principal amount of such Bond so surrendered a fully registered Bond of like maturity in any of the authorized denominations. (C)	If, on the redemption date, moneys for the redemption of all Bonds or portions thereof to be redeemed, in an amount equal to the principal of such Bonds or portions thereof to be redeemed, together with any premium due thereon and interest thereon to the redemption date, shall be held by the Trustee so as to be available therefor on such date, the Bonds or portions thereof so called for redemption shall cease to bear interest, and such Bonds or portions thereof shall no longer be Outstanding hereunder or be secured by or be entitled to the benefits of this Indenture. If such moneys shall not be so available on the redemption date, such Bonds or portions thereof shall continue to bear interest until paid at the same rate as they would have borne had they not been called for redemption and shall continue to be secured by and be entitled to the benefits of this Indenture. SECTION 304. MANDATORY TENDER; NOTICE. (A) The Bonds are subject to Mandatory Tender upon the exercise by the Company of the Conversion Option or the delivery by the Company of an Alternate Letter of Credit. (B)	Upon the exercise by the Company of the Conversion Option with respect to the Bonds, all such Bonds which have not been called for redemption shall be subject to Mandatory Tender by the owner thereof on the Conversion Date. Notwithstanding the foregoing, each Bondholder may, by delivery to the Trustee for receipt at least by twenty (20) days immediately preceding the Conversion Date of an irrevocable election not to tender, elect to continue to hold its Bonds (or portions thereof) past the Conversion Date at a Fixed Rate to be in effect at such time. Such notice shall be in substantially the form of Exhibit C-2 attached hereto. (C)	Not earlier than sixty (60) days prior to the Conversion Date or later than thirty (30) days prior to the Conversion Date, the Trustee shall send a notice to the owners of all Outstanding Bonds which have not been called for redemption, in substantially the form of Exhibit C-1 attached hereto. Such notice shall describe (1) the terms of the Mandatory Tender, (2) the right of the owner to elect not to tender, (3) the Letter of Credit to be in effect following the Mandatory Tender, (4) the right of the owner of Bonds in an aggregate amount of $200,000 or more to elect not to tender the total principal amount and to continue to hold a portion of its Bonds (but in no event may either the amount tendered or the amount not tendered be any amount other than $100,000, or any integral multiple of $5,000 in excess thereof) and (5) that the rating then in effect with respect to the Bonds, if any, may be withdrawn or lowered. (D)	In the event that prior to the Conversion Date of the Bonds the Company shall deliver notice to the Trustee at least sixty (60) days prior to the expiration of the Letter of Credit or Substitute Letter of Credit securing such Bonds of its intent to deliver an Alternate Letter of Credit pursuant to the terms of Section 5.8(A)(2) of the Installment Sale Agreement in substitution for such Letter of Credit or Substitute Letter of Credit, all Bonds secured by such Letter of Credit which have not been called for redemption shall be subject to Mandatory Tender by the owner thereof on the Alternate Security Date. Notwithstanding the foregoing, each Bondholder may, by delivery to the Trustee for receipt at least twenty (20) days immediately preceding any Alternate Security Date of an irrevocable election not to tender, elect to continue to hold its Bonds past the respective Alternate Security Date. Such notice shall be in substantially the form of Exhibit C-4 attached hereto. (E)	Not earlier than sixty (60) days prior to the Alternate Security Date or later than thirty (30) days prior to the Alternate Security Date, the Trustee shall send a notice to the owners of all Outstanding Bonds which have not been called for redemption, in substantially the form of Exhibit C-3 attached hereto. Such notice shall describe (1) the terms of the Mandatory Tender, (2) the right of the owner to elect not to tender, (3) a brief description of the Alternate Letter of Credit and the identity of the Substitute Bank issuing the Alternate Letter of Credit, (4) the right of the owner of Bonds in an aggregate amount of $200,000 or more to elect not to tender the total principal amount and to continue to hold a portion of its Bonds (but in no event may either the amount tendered or the amount not tendered be any amount other than $100,000 or any integral multiple of $5,000 in excess thereof) and (5) that the rating then in effect with respect to the Bonds secured by such Alternate Letter of Credit will be withdrawn or lowered. (F)	Owners of Bonds required to be tendered who do not provide the Trustee with the notice of their election not to tender as described in Section 304 hereof shall be required to deliver their Bonds to the Trustee for purchase at the Purchase Price on the Conversion Date or the Alternative Security Date, as the case may be, with an appropriate endorsement for transfer or accompanied by a bond power endorsed in blank. Any such Bonds not so delivered on such Conversion Date or the Alternate Security Date, as the case may be ("Undelivered Bonds"), for which there has been irrevocably deposited in trust with the Trustee an amount of moneys sufficient to pay the Purchase Price of the Undelivered Bonds, shall be deemed to have been purchased pursuant to this Section 304. IN THE EVENT OF A FAILURE BY AN OWNER OF BONDS REQUIRED TO BE TENDERED (OTHER THAN AN OWNER OF BONDS WHO HAS GIVEN NOTICE OF ITS ELECTION NOT TO TENDER AS PROVIDED ABOVE) TO DELIVER ITS BONDS ON OR PRIOR TO THE CONVERSION DATE OR THE ALTERNATE SECURITY DATE, SAID OWNER SHALL NOT BE ENTITLED TO ANY PAYMENT (INCLUDING ANY INTEREST TO ACCRUE ON OR SUBSEQUENT TO THE CONVERSION DATE OR THE ALTERNATE SECURITY DATE) OTHER THAN THE PURCHASE PRICE FOR SUCH UNDELIVERED BONDS, AND ANY UNDELIVERED BONDS SHALL NO LONGER BE ENTITLED TO THE BENEFITS OF THE INDENTURE, EXCEPT FOR THE PURPOSE OF PAYMENT OF THE PURCHASE PRICE THEREFOR. SECTION 305. DEMAND PURCHASE OPTION. (A) Prior to the Conversion Date, any Bond shall be purchased at the Purchase Price from the Owner thereof upon: (1)	delivery to, and receipt by, the Tender Agent or the Trustee at the addresses set forth in Section 1103 hereof on a Business Day of a Tender Notice which requests the purchase of the Bond.

Such Tender Notice shall provide the following information: (a) the principal amount of the Tendered Bond or portion thereof to be purchased, which portion shall be $100,000 or an integral multiple of $5,000 in excess thereof; provided, however, that no portion of a Tendered Bond shall be purchased if it results in the unpurchased portion of the Tendered Bond being less than $100,000, (b) the number of the Tendered Bond, (c) the date on which the Tendered Bond shall be purchased, which date shall be a Business Day at least seven (7) calendar days following the receipt by the Trustee or the Tender Agent of the Bondholder's Tender Notice (the "Repurchase Closing Date"), (d) the name and address of the Bondholder, (e) an irrevocable request of such purchase, and (f) an undertaking of the Bondholder to deliver the Bond to the Tender Agent or the Trustee in accordance with Section 305(A)(2) of the Indenture; (2)	delivery of the Tendered Bond, at the office of the Trustee or Tender Agent at or prior to 10:00 a.m., New York City time on the Repurchase Closing Date with an appropriate endorsement for transfer or accompanied by a bond power endorsed in blank; provided, however, the Tendered Bond shall only be deemed properly tendered hereunder if the Tendered Bond delivered to the Tender Agent or the Trustee conforms in all respects to the description thereof in the Bondholder's Tender Notice; and (3)	in the event the Tender Agent or the Trustee, as the case may be, determines that the Bondholder's Tender Notice is defective in any respect whatsoever, the Tender Agent or the Trustee, as the case may be, shall immediately notify the Bondholder tendering the Bond. (B)	Immediately upon receipt of a Bondholder's Tender Notice, the Tender Agent or the Trustee, as the case may be, shall notify the Company, the Remarketing Agent, the Bank and the Trustee or the Tender Agent, as the case may be, by Immediate Notice and shall promptly send a copy of such Bondholder's Tender Notice to the Company, the Remarketing Agent and the Trustee or the Tender Agent, as the case may be. (C)	(1) Bonds which are the subject of a Bondholder's Tender Notice described in (A)(1) above, but which are not tendered in accordance with (A)(2) above, shall be deemed tendered and all rights of the holder thereof shall be satisfied from the deposit with the Tender Agent or the Trustee of the Purchase Price thereof and the Tender Agent or the Trustee, as the case may be, shall hold such Purchase Price in trust for the benefit of such holder until the Bonds purchased with such moneys shall have been delivered to or for the account of such holder; and (2)	Holders of Tendered Bonds which are not delivered to the Tender Agent or the Trustee by the holder thereof shall have no further rights with respect to such Bonds except to receive payment of the Purchase Price therefor upon surrender of such Bonds to the Tender Agent or the Trustee. (D)	Notwithstanding the foregoing, the Bondholders shall have no Demand Purchase Option described in Section 305 hereof if (1) there shall have occurred and be continuing an Event of Default hereunder, except for an Event of Default under Section 601(I) hereof, or (2) the Fixed Rate is in effect for the Bonds being held by such Bondholder. (E)	Furthermore, no Bondholder shall have the right to exercise a Demand Purchase Option pursuant to Section 305 hereof with respect to those Bonds for which a notice of redemption has been mailed by the Trustee.

(C)	Upon the occurrence and continuance of any Event of Default, the Trustee may pursue any available remedy at law or in equity by suit, action, mandamus or other proceeding to enforce payment of and receive any amounts due or becoming due from the Issuer, the Bank or the Company under any of the provisions of this Indenture, the Installment Sale Agreement and the other Financing Documents, without prejudice to any other right or remedy of the Trustee or the Bondholders. (D)	Regardless of the happening of an Event of Default, the Trustee may institute and maintain such suits and proceedings as it may be advised shall be necessary or expedient to prevent any impairment of the security under this Indenture and the other Financing Documents by any acts which may be unlawful or in violation of the Indenture or of any other Financing Document or of any resolution authorizing the Bonds, or to preserve or protect the interest of the Trustee and/or the Bondholders. (E)	Notwithstanding anything to the contrary herein, so long as the Letter of Credit is in effect and the Bank is making all required payments with respect to the Letter of Credit in accordance with the terms of the Letter of Credit, the Trustee shall not exercise any remedies under this Article VI and the Trustee shall not, without the prior written consent of the Bank, take any actions which the Trustee is required or entitled to take under this Article VI unless and until the Trustee shall have accelerated the Bonds and drawn upon the Letter of Credit in accordance with Section 602 hereof and the Bank shall have defaulted in the performance of its obligations under the Letter of Credit, in which case the Bank shall have no authority to exercise any further rights hereunder. (F)	In the event of a default by the Bank in the performance of its obligations under the Letter of Credit, notwithstanding the provisions of subparagraph (E) above, the Bank shall have no authority to exercise any further rights hereunder, unless and until said default shall have been cured by the Bank to the satisfaction of the Trustee. (G)	Notwithstanding any other provision of this Indenture, failure of the Company or the Trustee to comply with the Continuing Disclosure Agreement shall not be considered an Event of Default; however, the Trustee may (and, at the request of any Underwriter or the Holders of at least twenty-five percent (25)% aggregate principal amount of Outstanding Bonds, shall) or any Bondholder may take such actions as may be necessary and appropriate, including seeking mandatory or specific performance by court order, to cause the Company to comply with its obligations under Section 8.5(B) of the Installment Sale Agreement or to cause the Trustee to comply with its obligations under Section 517(B) hereof. SECTION 604. APPOINTMENT OF RECEIVERS. Upon the occurrence and continuance of an Event of Default and upon the filing of a suit or commencement of other judicial proceedings to enforce the rights of the Trustee under the Indenture and the other Financing Documents, the Trustee shall be entitled, as a matter of right, to the appointment of a receiver or receivers of the Project Facility and of the revenues and receipts thereof, pending such proceedings, with such powers as the court making such appointment shall confer. SECTION 605. RIGHTS OF BONDHOLDERS TO OBLIGATE TRUSTEE TO PROTECT BONDHOLDERS. If an Event of Default shall have happened, and if requested so to do by the holders of not less than twenty-five percent (25%) in aggregate principal amount of Bonds then Outstanding, and if secured and indemnified as provided in Section 701(I) herein, the Trustee shall be obligated to proceed to protect its rights and the rights of the Bondholders under applicable law, the Installment Sale Agreement, the Bonds, the Letter of Credit, the Indenture and the other Financing Documents, as the Trustee, being advised by Independent Counsel, shall deem most expedient in the interest of the Bondholders. SECTION 606. REMEDIES NOT EXCLUSIVE; WAIVER AND NON-WAIVER OF EVENT OF DEFAULT. (A) No remedy by the terms of the Indenture conferred upon or reserved to the Trustee or to the Bondholders is intended to be exclusive of any other remedy, but each and every such remedy shall be cumulative and shall be in addition to any other remedy given to the Trustee or to the Bondholders hereunder or now or hereafter existing at law or in equity or by statute. (B)	No delay or omission to exercise any right or power accruing upon any Event of Default shall impair any such right or power or shall be construed to be a waiver of any such Event of Default or acquiescence therein; and every such right and power may be exercised from time to time and as often as may be deemed expedient. (C)	No waiver of any Event of Default hereunder, whether by the Trustee or by the Bondholders, shall extend to or shall affect any subsequent or concurrent Event of Default or shall impair any rights or remedies consequent thereto. SECTION 607. RIGHTS OF BONDHOLDERS TO DIRECT PROCEEDINGS. Anything in the Indenture to the contrary notwithstanding, the Holders of a majority in aggregate principal amount of Bonds then Outstanding shall have the right at any time, by an instrument in writing executed and delivered to the Trustee and upon offering the Trustee the security and indemnity provided for in Section 701(I) herein, to direct the time, method and place of conducting all proceedings to be taken in connection with the enforcement of the terms and conditions of the Indenture, the Letter of Credit, the Installment Sale Agreement or the other Financing Documents, or for the appointment of a receiver or any other proceedings hereunder, provided that such direction is in accordance with the provisions of law, and is not unduly prejudicial to the interests of the Bondholder not joining such direction. SECTION 608. WAIVER BY ISSUER. Upon the occurrence of an Event of Default, to the extent that such right may then lawfully be waived, neither the Issuer, nor anyone claiming through or under it, shall set up, claim or seek to take advantage of any appraisal, valuation, stay, extension or redemption laws now or hereafter in force, in order to prevent or hinder the enforcement of the Indenture or the foreclosure of the mortgage Lien on the Project Facility created by the Mortgage; and the Issuer, for itself and all who may claim through or under it, hereby waives, to the extent that it may lawfully do so, the benefit of all such laws and all rights of appraisal and redemption to which it may be entitled under the laws of the State. SECTION 609. APPLICATION OF MONEYS. (A) Except as provided in subsection (C) below, all moneys received by the Trustee pursuant to any right given or action taken under the provisions of this Article VI shall, after payment of the cost and expenses of the proceedings resulting in the collection of such moneys and of the fees, expenses, liabilities and advances incurred or made by the Trustee, be deposited into the Bond Fund; and all moneys in the Bond Fund shall be applied, together with the other moneys held by the Trustee hereunder, as follows: (1)	Unless the principal of all the Bonds shall have become due or shall have been declared due and payable, all such moneys shall be applied: FIRST - to the payment to the Persons entitled thereto of all installments of interest then due on the Bonds, in the order of the maturity of the installments of such interest and, if the amount available shall not be sufficient to pay in full any particular installment, then to the payment ratably, according to the amounts due on such installment, to the Persons entitled thereto, without any discrimination or privilege; SECOND - to the payment to the Persons entitled thereto of the unpaid principal of and any premium on the Bonds (other than Bonds called for redemption for the payment of which moneys shall be held pursuant to the provisions of the Indenture) which shall have become due, in order of their maturities, with interest from the date upon which they became due and, if the amount available shall not be sufficient to pay in full the principal of and premium, if any, and interest on the Bonds due on any particular date, then to the payment ratably, according to amounts due respectively for principal, interest and premium, if any, to the Persons entitled thereto, without any discrimination or privilege; THIRD - to the payment to the Persons entitled thereto of the principal of, premium, if any, on, or interest on the Bonds which may thereafter become due and payable, and, if the amount available shall not be sufficient to pay in full Bonds due on any particular date, together with interest and premium, if any, then due and owing thereon, payment shall be made ratably according to the amount of interest, principal and premium, if any, due on such date to the Persons entitled thereto, without any discrimination or privilege; and FOURTH - to the Bank. (2)	If the principal of all the Bonds shall have become due or shall have been declared due and payable, all such moneys shall be applied to the payment of the principal, premium, if any, and interest then due and unpaid upon the Bonds, without preference or priority of principal and premium over interest or of interest over principal and premium, or of any installment of interest over any other installment of interest, or of any Bonds over any other Bonds, ratably, according to the amounts due respectively for principal, premium, if any, and interest, to the Persons entitled thereto without any discrimination or privilege. (3)	If the principal of all the Bonds shall have been declared due and payable, and if such declaration shall thereafter have been rescinded and annulled under the provisions of paragraph (A)(2) of this Section 609 in the event that the principal of all the Bonds shall later become due or be declared due and payable, the moneys shall be applied in accordance with the provisions of paragraph (A)(1) of this Section. (B)	Whenever moneys are to be applied pursuant to the provisions of Section 609(A)(1) hereof, such moneys shall be applied at such times, and from time to time, as the Trustee shall determine, having due regard to the amount of such moneys available for such application and the likelihood of additional moneys becoming available in the future. Whenever the Trustee shall apply such moneys under Section 609(A)(1), it shall fix the date (which shall be an Interest Payment Date unless it shall deem another date more suitable) upon which such application is to be made, and upon such date interest on the amounts of principal to be paid on such date shall cease to accrue. Whenever moneys are to be applied pursuant to the provisions of Section 609(A)(2), such moneys shall be applied immediately upon receipt thereof. In either case, the Trustee shall give such notice as it may deem appropriate of the deposit with it of any such moneys and of the fixing of any such date, and shall not be required to make payment to the holder of any Bond until such Bond shall be presented to the Trustee and a new Bond is issued or the Bond is cancelled if fully paid. (C)	Any moneys received by the Trustee from the Bank pursuant to the exercise of any rights granted hereunder or under the Letter of Credit shall first be applied in accordance with Section 408 hereof. SECTION 610. REMEDIES VESTED IN TRUSTEE. All rights of action, including the right to file proof of claims, under the Indenture or under any of the Bonds may be enforced by the Trustee without the possession of any of the Bonds or the production thereof in any trial or other proceedings relating thereto, and any such suit or proceeding instituted by the Trustee shall be brought in its name as Trustee without the necessity of joining as plaintiffs or defendants any holders of the Bonds. Subject to the provisions of Section 609 hereof and any recovery or judgment shall be for the equal benefit of the holders of the Outstanding Bonds. SECTION 611. RIGHTS AND REMEDIES OF BONDHOLDERS. No holder of any Bond shall have any right to institute any suit, action or proceeding in equity or at law for the enforcement of the Indenture or for the execution of any trust under the Indenture or for the appointment to the extent permitted by law of a receiver or any other remedy hereunder, unless an Event of Default under Section 601(A) through (H) hereof has occurred or a default under Section 601(I) hereof has occurred of which the Trustee has been notified as provided in Section 614 hereof; nor unless also (A) such default, in the case of a default under Section 601(I), shall have become an Event of Default, and (B) the holders of at least twenty-five percent (25%) in aggregate principal amount of Bonds then Outstanding shall have made written request to the Trustee and shall have offered reasonable opportunity either to proceed to exercise the powers hereinbefore granted or to institute such action, suit or proceeding in its own name; nor unless also they have offered to the Trustee indemnity as provided in Section 701(I) hereof; nor unless the Trustee shall thereafter fail or refuse to exercise the powers hereinbefore granted, or to institute such action, suit or proceeding; and such notification, request and offer of indemnity are hereby declared in every case at the option of the Trustee to be conditions precedent to the execution of the powers and trusts of the Indenture, and to any action or cause of action for the enforcement of the Indenture, or for the appointment to the extent permitted by law of a receiver or for any other remedy hereunder; it being understood and intended that no one or more holders of the Bonds shall have any right in any manner whatsoever to affect, disturb, or prejudice the Lien of the Indenture by any action or to enforce any right hereunder except in the manner herein provided, and that all proceedings at law or in equity shall be instituted, had and maintained in the manner herein provided and for the equal benefit of the holders of all Bonds then Outstanding.

SECTION 612. TERMINATION OF PROCEEDINGS. In case the Trustee shall have undertaken any proceedings to enforce any right under the Indenture and such proceedings shall have been discontinued or abandoned for any reason, or shall have been determined adversely, then and in every such case, the Issuer, the Company, the Bank and the Trustee shall be restored to their former positions and rights hereunder, and all rights, remedies and powers of the Trustee shall continue as if no such proceedings had been taken. SECTION 613. WAIVERS OF EVENTS OF DEFAULT. The Trustee, with the prior written consent of the Bank, shall waive any Event of Default hereunder and its consequences and rescind any declaration of maturity of principal of and interest on the Bonds upon the written request of the holders of a majority of the aggregate principal amount of all the Bonds then Outstanding; provided, however, that there shall not be waived (A) any default in the payment of the principal of any Outstanding Bond at the date of maturity specified therein, or upon proceedings for mandatory redemption, (B) any Event of Default requiring a draw under the Letter of Credit unless the Trustee shall have received written notice from the Bank that the Letter of Credit has been reinstated to its full stated amount, if there has been a reduction thereon, or (C) any default in the payment when due of the interest or premium on any such Bonds, unless prior to such waiver or rescission all arrears of interest, with interest (to the extent permitted by law) at the rate borne by the Bonds in respect of which such default shall have occurred on overdue installments of interest or all arrears of payments of principal when due (whether at the stated maturity thereof or upon proceedings for redemption) as the case may be, shall have been paid or provided for, and no such waiver or rescission shall extend to any subsequent or other default, or impair any right consequent thereto. The Trustee shall not grant any waiver or rescission hereunder unless all ordinary and extraordinary fees and expenses of the Trustee, including, but not limited to, reasonable attorneys' fees, incurred in connection with said default have been paid or provided for, and in case of any such waiver or rescission, or in case any proceeding taken by the Trustee on account of any such default shall have been discontinued or abandoned or determined adversely, then, and in every such case, the Issuer, the Trustee, the Bank and the Bondholders, respectively, shall be restored to their former positions and rights hereunder. SECTION 614. NOTICE OF DEFAULTS; OPPORTUNITY TO CURE. (A) Anything herein to the contrary notwithstanding, no default under Section 601(I) hereof shall constitute an Event of Default until the Trustee shall have received written notice thereof or shall have actual notice thereof and until actual notice of such default by registered or certified mail shall be given by the Trustee or by the holders of not less than twenty-five (25%) percent of the aggregate principal amount of Bonds then Outstanding to the Issuer, the Bank and the Company, and the Issuer, the Bank and the Company shall have had thirty (30) days after receipt of such notice to correct said default or cause said default to be corrected, and shall not have corrected said default or caused said default to be corrected within the applicable period; provided, however, if said default be such that it cannot be corrected within the applicable period, it shall not constitute an Event of Default if corrective action is instituted by the Issuer, the Bank or the Company within the applicable period and diligently pursued until the default is corrected. (B)	The Trustee shall immediately notify the Issuer, the Company and the Bank of any Event of Default known to the Trustee. SECTION 615. STATEMENT OF INCOME AND EXPENDITURES. Upon the occurrence and continuance of an Event of Default, the Trustee shall render annually to the Bondholders a summarized statement of income and expenditures in connection with the Project Facility, but only to the extent, if any, that the Trustee can obtain such information without unreasonable effort or expense. ARTICLE VII THE TRUSTEE SECTION 701. ACCEPTANCE OF TRUSTS. The Trustee hereby accepts the trusts imposed upon it by the Indenture and agrees to perform said trusts upon the following terms and conditions: (A)	The Trustee may execute any of the trusts or powers hereof and perform any of its duties hereunder by or through attorneys, agents, receivers or employees, but shall not be answerable for the conduct of the same if appointed with due care, and shall be entitled to advice of counsel concerning all matters of the trusts hereof and the duties hereunder, and may in all cases pay such reasonable compensation to all such attorneys, agents, receivers and employees as may be reasonably employed in connection with the trusts hereof. The Trustee may act upon the opinion or advice of any attorney, who may be the attorney or attorneys for the Issuer, and shall not be responsible for any loss or damage resulting from any action or nonaction in reliance upon any such opinion or advice. (B)	Except as expressly provided herein, the Trustee shall not be responsible for any recital herein or in the Bonds (except in respect to the authentication certificate of the Trustee endorsed on the Bonds), or for the validity of the execution by the Issuer of the Indenture or of any supplements thereto or instruments of further assurance, or for the sufficiency of the security for the Bonds issued hereunder or intended to be secured hereby, or for insuring the Property subject to the Lien of the Financing Documents, or for the value or title of any of the Property subject to the Lien of the Financing Documents, or for the payment of, or for minimizing taxes, charges, assessments or Liens upon the same, or otherwise as to the maintenance of the security hereof, except as to the safekeeping of the pledged collateral and except that, in the event the Trustee enters into possession of part or all of the Property subject to the Lien of the Financing Documents pursuant to any provision thereof, it shall use due diligence in preserving the same, and the Trustee shall not be bound to ascertain or inquire as to the performance or observance of any covenant, condition or agreement on the part of the Issuer or the Company, but the Trustee may require of the Issuer and the Company full information and advice as to the performance of the covenants, conditions and agreements aforesaid and as to the condition of the Property subject to the Lien of the Financing Documents. (C)	The Trustee may become the owner of Bonds secured hereby with the same rights which it would have if not the Trustee. (D)	The Trustee shall be protected in acting upon any notice, request, consent, certificate, order, affidavit, letter, telegram or other paper or document reasonably believed to be genuine and correct and to have been signed or sent by the proper Person or Persons. Any action taken by the Trustee pursuant to the Indenture upon the request or authority or consent of any Person who at the time of making such request or giving such authority or consent is the owner of any Bond shall be conclusive and binding upon all future owners of the same Bond and of any Bond or Bonds issued in exchange therefore or in place thereof. (E)	The Trustee may accept a certificate of the Secretary or Assistant Secretary of the Issuer under its corporate seal to the effect that a resolution in the form therein set forth has been adopted by the Issuer as conclusive evidence that such resolution has been duly adopted and is in full force and effect. As to the existence or nonexistence of any fact or as to the sufficiency or validity of any instrument, paper or proceeding, the Trustee shall be entitled to rely upon a certificate of the Company or the Bank signed by an Authorized Representative of the Company or the Bank, as the case may be, or a certificate of an Authorized Representative of the Issuer under seal, as sufficient evidence of the facts therein contained and, prior to the occurrence of a default of which it has been notified as provided in paragraph (M) of this Section or of which by said paragraph it is deemed to have notice, shall also be at liberty to accept a similar certificate to the effect that any particular dealing, transaction or action is or is not necessary or expedient, but may at its discretion, at the reasonable expense of the Company, in every case secure such further evidence as it may think necessary or advisable, but shall in no case be bound to secure the same. (F)	The permissive right of the Trustee to do things enumerated in the Indenture shall not be construed as a duty unless so specified herein, and in doing or not doing so the Trustee shall not be answerable for other than its own gross negligence or willful misconduct. (G)	At any and all reasonable times, the Trustee, and its duly authorized agents, attorneys, experts, accountants and representatives, shall have the right fully to inspect all books, papers and records of the Issuer pertaining to the Project Facility and the Bonds, and to take such memoranda from and in regard thereto as may be desired. (H)	Notwithstanding anything elsewhere in the Indenture, the Trustee shall have the right, but shall not be required, to demand, in respect of the authentication of any Bonds, the withdrawal of any moneys, the release of any interest in Property or any action whatsoever, within the purview of the Indenture, any showings, certificates, opinions, appraisals or other information, or corporate action or evidence thereof, in addition to those required herein. (I)	Before taking any action hereunder (except declaring an Event of Default or drawing under the Letter of Credit on an Interest Payment Date or a Bond Payment Date), the Trustee may require that a security and indemnity reasonably satisfactory to it be deposited with it for the reimbursement of all fees, costs and expenses including, but not limited to, reasonable attorney's fees to which it may be put and to protect it against all liability, except liability which is adjudicated to have resulted from its gross negligence or willful misconduct by reason of any action so taken. (J)	All moneys received by the Trustee or any paying agent shall, until used or applied or invested as herein provided, be held in trust for the purposes for which they were received, but need not be segregated from other funds except to the extent required by law or by the Indenture. Neither the Trustee nor any paying agent shall be under any liability for interest on any moneys received hereunder except such as may be agreed upon with the Issuer. (K)	The Trustee, prior to an Event of Default hereunder and after curing all Events of Default which may have occurred, undertakes to perform only such duties as are specifically set forth in the Indenture. In case an Event of Default has happened which has not been cured, the Trustee shall exercise the rights, duties and powers vested in it by the Indenture in good faith and with that degree of diligence, care and skill which ordinarily prudent persons would exercise under similar circumstances in handling their own affairs. (L)	The Trustee shall furnish to the Issuer during the term of this Indenture upon the written request of the Issuer any reports or other account of the use of any of the Issuer's funds held by the Trustee that may be required by any governmental body. (M)	The Trustee shall not be required to take notice or be deemed to have notice of the occurrence of any Event of Default other than an Event of Default under Section 601(A) through (H), unless the Trustee shall have actual notice of such Event of Default or unless the Trustee shall be specifically notified in writing of such Event of Default by the Issuer, the Bank or the Company or by the owners of at least twenty-five percent (25%) in aggregate principal amount of Bonds Outstanding hereunder, and all notices or other instruments required by this Indenture to be delivered to the Trustee must, in order to be effective, be delivered at the main office of the Trustee, and, in the absence of such notice so delivered, the Trustee may conclusively assume there is no Event of Default, except as aforesaid. (N)	The Trustee shall not be personally liable for any debts contracted or for damages to Persons or to personal Property injured or damaged, or for salaries or nonfulfillment of contracts, during any period in which it may be in the possession of or managing any Property subject to the Lien of the Financing Documents as in this Indenture provided. (O)	The Trustee shall not be required to give any bond or surety in respect of the execution of the said trusts and powers or otherwise in respect of the premises. (P)	There shall be no additional fee charged by the Trustee for a draw under the Letter of Credit as contemplated by Section 408 hereof or by the terms of the Letter of Credit. Nothing in the foregoing sentence, however, shall limit the Trustee's right to charge additional fees in the event it is required to perform Extraordinary Services hereunder. (Q)	Before taking any action hereunder, or under the Mortgage or any other Financing Document, which would result in the Trustee acquiring title to or taking possession of any portion or all of the Project Facility, the Trustee may require such environmental inspections and tests of the Project Facility and other environmental reviews as the Trustee deems necessary and if the Trustee determines that the taking of title or possession of all or any portion of the Project Facility will expose it to claims or damages resulting from environmental or ecological conditions in any way relating to the Project Facility or any activities at the Project Facility, the Trustee may decline to take title to or possession of the Project Facility. SECTION 702. FEES, CHARGES AND EXPENSES OF TRUSTEE. The Trustee shall be entitled to payment for its Ordinary Services and Ordinary Expenses, including, but not limited to, reasonable attorney's fees, rendered or incurred hereunder and, in the event that it should become necessary for the Trustee to perform Extraordinary Services, it shall be entitled to reasonable extra compensation therefor, and to reimbursement for reasonable and necessary Extraordinary Expenses, including, but not limited to, reasonable attorney's fees, in connection therewith; provided that, if such Extraordinary Services or Extraordinary Expenses are occasioned by the gross negligence or willful misconduct of the Trustee, it shall not be entitled to compensation or reimbursement therefor. SECTION 703. NOTICE TO BONDHOLDERS OF DEFAULT. If an Event of Default occurs of which the Trustee is, by Section 614 or paragraph (M) of Section 701 hereof, required to take notice or if notice of an Event of Default has been given to it as in said Section 614 or paragraph (M) provided, then the Trustee shall give written notice thereof by mail to all owners of Bonds then Outstanding as shown on the bond register maintained by the Trustee. SECTION 704. INTERVENTION BY TRUSTEE. In any judicial proceeding to which the Issuer is a party and which in the opinion of the Trustee and its counsel has a substantial bearing on the interests of Bondholders, the Trustee may intervene on behalf of Bondholders and shall do so if requested in writing by the owners of at least twenty-five percent (25%) in aggregate principal amount of all Bonds then Outstanding if offered the security and indemnity provided for in Section 701(I). The rights and obligations of the Trustee under this Section 704 are subject to the approval of a court of competent jurisdiction. SECTION 705. SUCCESSOR TRUSTEE. Any corporation or association into which the Trustee may be converted or merged, or with which it may be consolidated, or to which it may sell or transfer its trust business and assets as a whole or substantially as a whole, or any corporation or association resulting from any such conversion, sale, merger, consolidation or transfer to which it is a party, shall, ipso facto, be and become successor Trustee hereunder and vested with all of the title to the Trust Revenues and all the trusts, powers, discretions, immunities, privileges and all other matters as was its predecessor, without the execution or filing of any instruments or any further act, deed or conveyance on the part of any of the parties hereto, anything herein to the contrary notwithstanding. SECTION 706. RESIGNATION BY TRUSTEE. The Trustee and any successor Trustee may at any time resign from the trusts hereby created by giving sixty (60) days' written notice to the Issuer, the Bank and the Company and by registered or certified mail to each owner of Bonds then Outstanding and such resignation shall take effect at the end of such sixty (60) days, but not prior to the acceptance of appointment by a successor Trustee under Section 709 hereof. Such notice to the Issuer, the Bank and the Company may be served personally or sent by registered mail. If an instrument of acceptance by a successor Trustee shall not be delivered to the Trustee within sixty (60) days after the giving of such notice of resignation, the resigning trustee may petition any court of competent jurisdiction for the appointment of a successor Trustee. SECTION 707. REMOVAL OF TRUSTEE. (A) The Trustee may be removed at any time, by an instrument or concurrent instruments in writing delivered to the Trustee, the Issuer, the Bank and the Company, and signed by the owners of a majority in aggregate principal amount of all Bonds then Outstanding. Such notice shall specify the date that such removal shall take effect. (B)	No removal of the Trustee under this Section 707 shall be effective until a successor Trustee shall have been appointed and shall have accepted the terms and conditions imposed hereby. SECTION 708. APPOINTMENT OF SUCCESSOR TRUSTEE BY BONDHOLDERS; TEMPORARY TRUSTEE. In case the Trustee hereunder shall resign or be removed, or be dissolved, or shall be in course of dissolution or liquidation, or otherwise become incapable of acting hereunder, or in case it shall be taken under the control of any public officer or officers, or of a receiver appointed by a court, a successor may be appointed by the owners of a majority in aggregate principal amount of Bonds then Outstanding, by an instrument or concurrent instruments in writing signed by such owners, or by their duly authorized attorneys; provided, nevertheless, that in case of vacancy, the Issuer by an instrument executed and signed by the Chairman or Vice Chairman and attested by the Secretary or Assistant Secretary of the Issuer under its seal, may appoint a temporary Trustee to fill such vacancy until a successor Trustee shall be appointed by such Bondholders in the manner above provided; and any such temporary Trustee so appointed by the Issuer shall immediately and without further act be superseded by the Trustee so appointed by such Bondholders. Every such successor or temporary Trustee appointed pursuant to the provisions of this Section 708 shall (A) be a trust company or bank organized under the laws of the United States of America or any state thereof and which is in good standing, (B) be located within or outside the State, (C) be duly authorized to exercise trust powers in the State, and (D) maintain a reported capital and surplus of not less than $5,000,000, or be a subsidiary of a bank holding company with such capital and surplus. SECTION 709. CONCERNING ANY SUCCESSOR TRUSTEE. Every successor Trustee appointed hereunder shall execute, acknowledge and deliver to its predecessor and also to the Issuer an instrument in writing accepting such appointment hereunder, and thereupon such successor, without any further act, deed or conveyance, shall become fully vested with all the estates, Properties, rights, powers, trusts, duties and obligations of its predecessor; but such predecessor shall, nevertheless, on the written request of the Issuer, or of its successor, and upon payment of all amounts due such predecessor, execute and deliver an instrument transferring to such successor Trustee all the estates, Properties, rights, powers and trusts of such predecessor hereunder; and every predecessor Trustee shall deliver all securities and moneys held by it as Trustee hereunder to its successor. Should any instrument in writing from the Issuer be required by a successor Trustee for more fully and certainly vesting in such successor the estates, Properties, rights, powers and duties hereby vested or intended to be vested in the predecessor, any and all such instruments in writing shall, on request, be executed, acknowledged and delivered by the Issuer. The resignation of any Trustee and the instrument or instruments removing any Trustee and appointing a successor hereunder, together with all other instruments provided for in this Article VII, shall be filed and/or recorded by the successor Trustee in each recording office where the Indenture shall have been filed and/or recorded. SECTION 710. TRUSTEE PROTECTED IN RELYING UPON RESOLUTIONS, ETC. The resolutions, opinions, certificates and other instruments provided for in the Indenture may be accepted by the Trustee as conclusive evidence of the facts and conclusions stated therein and shall be full warrant, protection and authority to the Trustee for the release of property and the withdrawal of moneys hereunder. SECTION 711. SUCCESSOR TRUSTEE AS TRUSTEE, PAYING AGENT AND BOND REGISTRAR. In the event of a change in the office of Trustee, the predecessor Trustee which has resigned or has been removed shall cease to be Trustee and paying agent on the Bonds and Bond Registrar, and the successor Trustee shall become such Trustee and paying agent and Bond Registrar. SECTION 712. TRUST MAY BE VESTED IN SEPARATE OR CO-TRUSTEE. (A) It is the purpose of the Indenture that there shall be no violation of any law of any jurisdiction, including particularly the law of the State, denying or restricting the right of banking corporations or associations to transact business as trustee in such jurisdiction. It is recognized that in case of litigation under the Indenture, and in particular in case of the enforcement of any such instrument on default, or in case the Trustee deems that by reason of any present or future law of any jurisdiction it may not exercise any of the powers, rights or remedies herein granted to the Trustee or hold title to the trust herein created, or take any other action which may be desirable or necessary in connection therewith, it may be necessary that the Trustee appoint an additional individual or institution as a separate or co-trustee.

Any consent, request, direction, approval, waiver, objection, appointment or other instrument required by the Indenture to be signed and executed by the Bondholders may be signed and executed in any number of concurrent writings of similar tenor and may be signed or executed by such Bondholders in person or by agent appointed in writing. Proof of the execution of any such instrument, if made in the following manner, shall be sufficient for any of the purposes of the Indenture, and shall be conclusive in favor of the Trustee with regard to any action taken under such instrument, namely: (A)	The fact and date of the execution by any Person of any such instrument may be proved by the affidavit of a witness of such execution or by the certificate of any notary public or other officer of any jurisdiction, authorized by the laws thereof to take acknowledgements of deeds, certifying to the execution thereof. Where such execution is by an officer of a corporation or association or a member of a partnership on behalf of such corporation, association or partnership, such affidavit or certificate shall also constitute sufficient proof of his authority. (B)	The ownership of Bonds shall be proven by the bond register. (C)	Any request, consent or vote of the holder of any Bond shall bind every future holder of the same Bond and the holder of every Bond issued in exchange therefor or in lieu thereof, in respect of anything done or permitted to be done by the Trustee or the Issuer pursuant to such request, consent or vote.

Only Bonds which the Trustee knows to be so owned shall be disregarded. Bonds so owned which have been pledged in good faith may be regarded as Outstanding for the purposes of this Section 1101 if the pledgee shall establish to the satisfaction of the Trustee the pledgee's right to vote such Bonds. In case of a dispute as to such right, any decision by the Trustee taken upon the advice of counsel shall be full protection to the Trustee. SECTION 1102. LIMITATION OF RIGHTS.

The Issuer shall not be liable for any action taken by it in good faith and reasonably believed by it to be within the discretion or power conferred upon it, or in good faith omitted to be taken by it and reasonably believed to be beyond such discretion or power, or taken by it pursuant to any direction or instruction by which it is governed under any Financing Document, or omitted to be taken by it by reason of the lack of direction or instruction required for such action under any Financing Document, and shall not be responsible for the consequences of any error of judgment reasonably made by it. When any payment, consent or other action by the Issuer is called for by the Indenture, the Issuer may defer such action pending an investigation or inquiry or receipt of such evidence, if any, as it may require in support thereof. A permissive right or power to act shall not be construed as a requirement to act, and no delay in the exercise of a right or power shall affect the subsequent exercise thereof.

(E)	In approving, concurring in or consenting to any action or in exercising any discretion or in making any determination under the Indenture, the Issuer may consider the interests of the public, which shall include the anticipated effect of any transaction on tax revenues and employment, as well as the interests of the other parties hereto and the Bondholders; provided, however, that nothing herein shall be construed as conferring on any Person other than the Trustee, the Bank and the Bondholders any right to notice, hearing or participation in the Issuer's consideration, and nothing in this Section 1109 shall be construed as conferring on any of them any right additional to those conferred elsewhere herein.

The principal of this Bond shall be paid on the Maturity Date upon presentation and surrender hereof at the Office of Manufacturers and Traders Trust Company, as trustee (together with its successors in trust, the "Trustee") under the trust indenture dated as of December 1, 1998 (from time to time, as amended or supplemented, the "Indenture") by and between the Issuer and the Trustee, or at the duly designated office of any successor trustee under the Indenture. The installments of interest described above shall, as provided in the Indenture, be paid to the Person in whose name this Bond (or one or more Predecessor Bonds, as defined in the Indenture) is registered at the close of business on the Business Day next preceding any Interest Payment Date (the "Regular Record Date"), and shall be paid by check or draft of the Trustee mailed by the Trustee on such Interest Payment Date to such registered owner at his address appearing on the registration books of the Issuer, or at the option of any holder of Bonds in an aggregate principal amount of $250,000 or greater be transmitted on such Interest Payment Date by wire transfer at such owner's written request to the bank account number on file with the Trustee. Any such interest not so punctually paid or duly provided for shall forthwith cease to be payable to the registered owner on such Regular Record Date, and may be paid to the Person in whose name this Bond (or one or more Predecessor Bonds) is registered at the close of business on a date for the payment of such defaulted interest to be fixed by the Trustee (the "Special Record Date"), notice whereof being given to registered owners of the Bonds not less than ten (10) days prior to such Special Record Date, or may be paid in any other lawful manner as shall be determined by the Trustee. The principal of, premium, if any, on and interest on this Bond are payable in lawful money of the United States of America. (Calculation of Interest) This Bond shall bear interest as follows: (a)	From the Closing Date through and including December 23, 1998, the Bonds shall bear interest at a rate per annum equal to five and fifty-five hundredths percent (5.55%). (b)	Thereafter, except as provided in (e) below, this Bond (other than Pledged Bonds) shall bear interest at the "Adjustable Rate". (i)	The Adjustable Rate shall be the rate of interest established by the Remarketing Agent on the first Business Day prior to each Adjustment Date, which in the Remarketing Agent's reasonable judgment would result, as nearly as practicable, in the market value of this Bond on an Adjustment Date being equal to one hundred percent (100%) of the principal amount thereof. The Adjustable Rate so determined shall be adjusted in accordance with the directions of the Remarketing Agent on the Adjustment Date and shall remain in effect through and including the day prior to the next following Adjustment Date. (ii)	In determining the Adjustable Rate pursuant to the foregoing paragraph (b)(i), the Remarketing Agent shall take into account, to the extent applicable, (A) the market interest rates for comparable securities held by open-end municipal or other fixed income bond funds or other institutional or private investors with substantial portfolios (w) with interest rate adjustment periods and demand purchase options substantially identical to the Bonds, (x) bearing interest at a variable rate intended to maintain par value, (y) rated by a national credit rating agency in the same category as the Bonds or, if not rated, secured by substantially the same level of security as the Bonds, and (z) the interest on which is included in gross income of the holders thereof for federal income taxation purposes; (B) other financial market rates and indices which may have a bearing on the Adjustable Rate (including, but not limited to rates borne by commercial paper, commercial paper, Treasury bills, commercial bank prime rates, certificate of deposit rates, federal funds rates, the London Interbank Offered Rate, indices maintained by The Bond Buyer, and other publicly available taxable interest rate indices); (C) general financial market conditions (including current forward supply); (D) factors particular to the Project or the credit standing of the Company and the Bank; and (E) such other factors which the Remarketing Agent deems appropriate. (iii)	On the Business Day prior to each Adjustment Date, the Remarketing Agent shall notify the Trustee, by Immediate Notice, of the Adjustable Rate. (c)	If for any reason the position of Remarketing Agent is vacant or the Remarketing Agent fails to act, the Adjustable Rate shall be determined by a third party selected by the Company at the Company expense and shall be equal to one hundred percent (100%) of the yield applicable to 13 week United States Treasury bills determined by such third party on the basis of the average per annum discount rate at which such 13- week Treasury bills shall have been sold (1) at the most recent Treasury auction conducted during the immediately preceding Adjustment Period, (2) if no such auction shall have been conducted during the immediately preceding Adjustment Period, at the most recent Treasury auction conducted prior to such preceding Adjustment Period, plus fifty (50) basis points; provided, however, that in the event the Company notifies the Trustee that an index (as published in The Wall Street Journal) of seven-day yield evaluations at par of issuers of securities, the interest on which is includable in gross income for federal income tax purposes, and of comparable rating to the rating on the Bonds, published by any nationally recognized municipal securities evaluation service is available, the Adjustable Rate shall be determined by the Trustee and shall be equal to such index. (d)	The Adjustable Rate shall be calculated based on a 365 or 366- day year for the actual number of days elapsed. Further, each determination of the Adjustable Rate pursuant to and in accordance with the foregoing terms of the Indenture and the terms of this Bond shall be conclusive and binding on the Issuer, the Trustee, the Company, the Bank, and the holder of this Bond. (e)	(i) From and after the Conversion Date through the maturity or earlier redemption of the Bonds, this Bond shall bear interest at the Fixed Rate, which shall be a fixed rate (or rates) of interest established by the Remarketing Agent at least fifteen (15), but not more than thirty (30) days prior to the Conversion Date, which in the reasonable judgment of the Remarketing Agent would result, as nearly as practicable, in the market value of this Bond on the Conversion Date being equal to one hundred percent (100%) of the principal amount thereof. (ii)	(A) At the Remarketing Agent's discretion, after the exercise of the Conversion Option, the Bonds may be converted into serial bonds, with a principal amount of Bonds maturing on a Principal Payment Date each year equal to the principal amount required to be redeemed as set forth in Section 301(E) of the Indenture. In such event, each maturity of Bonds may bear a different interest rate, each of which shall be determined by the Remarketing Agent in the same manner as the Fixed Rate (for convenience each such rate shall be referred to as the Fixed Rate); provided, however, that in no event shall the Remarketing Agent be permitted to convert the Bonds into serial bonds as described above without delivering to the Trustee an opinion of Bond Counsel that such conversion is lawful under the Act and permitted under the Indenture. (B)	The Interest Payment Dates after the exercise of the Conversion Option shall be semi-annual, with one Interest Payment Date being the first day of the month preceding the Fixed Rate Conversion Date and the other Interest Payment Date being the first day of the month six (6) months later. Principal shall be payable annually thereafter in the amounts and the years set forth in Section 301(E) hereof on the Principal Payment Dates. (iii)	In determining the Fixed Rate, the Remarketing Agent shall take into account, to the extent applicable, (A) market interest rates for comparable securities which are held by open-end municipal or other fixed income bond funds or other institutional or private investors with substantial portfolios (w) with a term equal to the period to maturity remaining on the Bonds, (x) the interest on which is included in the gross income of the holders thereof for federal income tax purposes, (y) rated by a national credit rating agency in the same rating category as the Bonds, or, if not rated, secured by substantially the same level of security as the Bonds, and (z) with redemption provisions similar to those which have bearing on the Fixed Rate; (B) other financial market rates and indices (including but not limited to rates borne by industrial development bonds, other taxable revenue bonds, Treasury obligations, commercial bank prime rates, certificate of deposit rates, federal funds rates, indices maintained by The Bond Buyer and other publicly available taxable interest rates and indices); (C) general financial market conditions (including current forward supply); (D) factors particular to the Project or the credit standing of the Company and the Bank; and (E) such other factors which the Remarketing Agent deems appropriate. (iv)	The Fixed Rate shall be calculated based on a 360-day year of twelve 30-day months. The determination of the Fixed Rate by the Remarketing Agent pursuant to and in accordance with the terms of the Indenture and the terms of this Bond shall be conclusive and binding on the Issuer, the Trustee, the Company, the Bank and the holder of this Bond. (v)	To exercise the Conversion Option, the Company shall deliver at least sixty (60) days prior to the Conversion Date, written notice to the Trustee, the Issuer and the Bank of its election of the Conversion Option. On the Conversion Date, this Bond shall be subject to a Mandatory Tender for purchase as provided in Section 304 of the Indenture. Notwithstanding anything to the contrary contained herein, such notice shall not be effective unless the Bank shall have consented thereto in writing and such notice is accompanied by: (A)	a Substitute Letter of Credit with an expiration date of not earlier than fifteen (15) days following the Principal Payment Date which is at least three (3) years after the next succeeding Principal Payment Date and in an amount equal to the sum of the aggregate principal amount of the Bonds then Outstanding, 210 days' interest thereon computed at the Fixed Rate, together with the Optional Redemption Premium; provided, however, that if the Letter of Credit then in place has an expiration date of not earlier than fifteen (15) days following the Principal Payment Date which is at least three (3) years after the next succeeding Principal Payment Date and in an amount equal to the aggregate principal amount of the Bonds then Outstanding, 210 days' interest thereon computed at the Fixed Rate, together with the Optional Premium, no Substitute Letter of Credit need be obtained; (B)	a statement as to whether the Bonds shall be serial bonds as set forth in paragraph (e)(ii) above; and (C)	an opinion of Bond Counsel reasonably satisfactory to the Trustee, the Issuer and the Bank to the effect that the exercise of the Conversion Option is lawful under the Act and permitted by the Indenture. (f)	Notwithstanding anything herein to the contrary, any Pledged Bond shall bear interest at a rate equal to the Bank Rate, as such rate shall change from time to time; provided, however, that at no time shall the interest rate in effect for any Pledged Bond exceed the maximum rate permitted by applicable usury laws. (g)	Notwithstanding anything herein to the contrary, in no event will the rate of interest borne by any Bond (except any Bond constituting a Pledged Bond) exceed fifteen percent (15%) per annum. (h)	The Issuer hereby appoints the Company to act as agent of the Issuer for purposes of exercising the Conversion Option, all as set forth in the Indenture, and subject to compliance with the terms and provisions of the Indenture. (Conversion Option) In the event the Company exercises the Conversion Option with respect to the Bonds, on the Conversion Date all Bonds which have not been called for redemption shall be subject to Mandatory Tender by the owners thereof on the Conversion Date. Notwithstanding the foregoing, each Bondholder may, by delivery to the Trustee for receipt at least twenty (20) days immediately preceding the Conversion Date of an irrevocable election not to tender, elect to continue to hold its Bonds (or portions thereof) past the Conversion Date at a Fixed Rate to be in effect at such time. Such notice shall be in substantially the form of Exhibit C-2 attached to the Indenture. Not earlier than sixty (60) days prior to the Conversion Date or later than thirty (30) days prior to the Conversion Date, the Trustee shall send a notice to the owners of all Outstanding Bonds which have not been called for redemption, in substantially the form of Exhibit C-1 attached to the Indenture. Such notice shall describe (a) the terms of the Mandatory Tender, (b) the right of the owner to elect not to tender, (c) the Letter of Credit to be in effect following the Mandatory Tender, (d) the right of the owner of Bonds in an aggregate amount of $200,000 or more to elect not to tender the total principal amount and to continue to hold a portion of its Bonds (but in no event may either the amount tendered or the amount not tendered be any amount other than $100,000, or any integral multiple of $5,000 in excess thereof), and (e) that the rating then in effect with respect to the Bonds, if any, may be withdrawn or lowered. In the event that prior to the Conversion Date of the Bonds the Company shall deliver notice to the Trustee at least sixty (60) days prior to the expiration of the Letter of Credit or Substitute Letter of Credit securing such Bonds of its intent to deliver an Alternate Letter of Credit in substitution for such Letter of Credit or Substitute Letter of Credit, all Bonds secured by such Letter of Credit which have not been called for redemption shall be subject to Mandatory Tender by the owner thereof on the Alternate Security Date. Notwithstanding the foregoing, each Bondholder may, by delivery to the Trustee for receipt at least twenty (20) days immediately preceding any Alternate Security Date of an irrevocable election not to tender, elect to continue to hold its Bonds past the respective Alternate Security Date. Such notice shall be in substantially the form of Exhibit C-4 attached to the Indenture. Not earlier than sixty (60) days prior to the Alternate Security Date or later than thirty (30) days prior to the Alternate Security Date, the Trustee shall send a notice to the owners of all Outstanding Bonds which have not been called for redemption, in substantially the form of Exhibit C-3 attached to the Indenture. Such notice shall describe (1) the terms of the Mandatory Tender, (2) the right of the owner to elect not to tender, (3) a brief description of the Alternate Letter of Credit and the identity of the Substitute Bank issuing the Alternate Letter of Credit, (4) the right of the owner of Bonds in an aggregate amount of $200,000 or more to elect not to tender the total principal amount and to continue to hold a portion of its Bonds (but in no event may either the amount tendered or the amount not tendered be any amount other than $100,000, or any integral multiple of $5,000 in excess thereof) and (5) that the rating then in effect with respect to the Bonds secured by such Alternate Letter of Credit will be withdrawn or lowered. Owners of Bonds required to be tendered who do not provide the Trustee with the notice of their election not to tender as described above shall be required to deliver their Bonds to the Trustee for purchase at the Purchase Price on the Conversion Date or the Alternate Security Date, as the case may be, with an appropriate endorsement for transfer or accompanied by a bond power endorsed in blank. Any such Bonds not so delivered on such Conversion Date or the Alternate Security Date, as the case may be ("Undelivered Bonds"), for which there has been irrevocably deposited in trust with the Trustee an amount of moneys sufficient to pay the Purchase Price of the Undelivered Bonds, shall be deemed to have been purchased. IN THE EVENT OF A FAILURE BY AN OWNER OF BONDS REQUIRED TO BE TENDERED (OTHER THAN AN OWNER OF BONDS WHO HAS GIVEN NOTICE OF ITS ELECTION NOT TO TENDER AS PROVIDED ABOVE) TO DELIVER ITS BONDS ON OR PRIOR TO THE CONVERSION DATE OR THE ALTERNATE SECURITY DATE, SAID OWNER SHALL NOT BE ENTITLED TO ANY PAYMENT (INCLUDING ANY INTEREST TO ACCRUE ON OR SUBSEQUENT TO SUCH CONVERSION DATE OR THE ALTERNATE SECURITY DATE) OTHER THAN THE PURCHASE PRICE FOR SUCH UNDELIVERED BONDS, AND ANY UNDELIVERED BONDS SHALL NO LONGER BE ENTITLED TO THE BENEFITS OF THE INDENTURE, EXCEPT FOR THE PURPOSE OF PAYMENT OF THE PURCHASE PRICE THEREFOR. (Demand Purchase Option) This Bond shall be purchased, at the option ("Demand Purchase Option") of the Owner hereof, at a price (the "Purchase Price") equal to one hundred percent (100%) of the principal amount hereof plus accrued and unpaid interest hereon to the Repurchase Closing Date (as hereinafter defined), upon: (A)	Delivery to, and receipt by, the Tender Agent at its designated address, or the Trustee at the address set forth herein on a Business Day of a written notice ("Bondholder's Tender Notice") which requests the purchase of the Bond. The Tender Notice shall be in substantially the form of Exhibit C-5 to the Indenture. Such Tender Notice shall provide the following information: (1) the principal amount of such Bond or portion thereof to be purchased (the "Tendered Bond"), which portion shall be $100,000 or an integral multiple of $5,000 in excess thereof; provided, however, that no portion of a Tendered Bond shall be purchased if it results in the unpurchased portion of the Tendered Bond being less than $100,000, (2) the number of the Tendered Bond, (3) the date on which the Tendered Bond shall be purchased, which date shall be a Business Day at least seven (7) calendar days following the receipt by the Trustee or the Tender Agent of the Bondholder's Tender Notice (the "Repurchase Closing Date"), (4) the name and address of the Bondholder, (5) an irrevocable request of such purchase, and (6) an undertaking of the Bondholder to deliver the Bond to the Tender Agent or the Trustee in accordance with (B) below; and (B)	Delivery of the Tendered Bond, at the office of the Trustee or Tender Agent at or prior to 10:00 a.m., New York City time, on the Repurchase Closing Date with an appropriate endorsement for transfer or accompanied by a bond power endorsed in blank; provided, however, the Tendered Bond shall only be deemed properly tendered hereunder if the Tendered Bond delivered to the Tender Agent or the Trustee conforms in all respects to the description thereof in the Bondholder's Tender Notice; and (C)	In the event the Tender Agent or the Trustee, as the case may be, determines that the Bondholder's Tender Notice is defective in any respect whatsoever, the Tender Agent or the Trustee, as the case may be, shall immediately notify the Bondholder tendering the Bond; and (D)	Bonds which are the subject of a Bondholder's Tender Notice described in (A) above, but which are not tendered in accordance with (B) above, shall be deemed tendered and all rights of the holder thereof shall be satisfied from the deposit with the Tender Agent or the Trustee of the Purchase Price thereof and the Tender Agent or the Trustee, as the case may be, shall hold such Purchase Price in trust for the benefit of such holder until the Bonds purchased with such moneys shall have been delivered to or for the account of such Holder. Holders of Tendered Bonds to be tendered which are not delivered to the Tender Agent or the Trustee by the holder thereof shall have no further rights with respect to such Bonds except to receive payment of the Purchase Price therefor upon surrender of such Bonds to the Tender Agent or the Trustee. Notwithstanding the foregoing, the Bondholders shall have no Demand Purchase Option described herein if (A) there shall have occurred and be continuing an Event of Default under the Indenture, except for an Event of Default under Section 601(I) of the Indenture or (B) the Fixed Rate is in effect for the Bonds being held by such Bondholder.
