The Variable Rate shall be the lesser of (i) the Maximum Interest Rate or (ii) a fluctuating per annum rate equal to the per annum rate for the for the one-week period commencing on a Thursday and ending on the Wednesday succeeding such Thursday (the “Accrual Period”) determined by the Remarketing Agent (herein defined) by 9:00 a.m., Portland, Oregon time, on the Wednesday preceding the day on which the Accrual Period commences or, if such day of determination is not a Business Day (herein defined) for the Remarketing Agent, on the first succeeding day which is a Business Day (the “Determination Date”), to be equal to (but not more than) the rate required to be borne by the Bonds for such Accrual Period to produce a bid for the purchase of all the Bonds on such Determination Date at a price equal to the principal amount thereof plus accrued interest, if any, thereon from the most recent Interest Payment Date. If for any reason the Variable Rate is not determined as set forth above on any Determination Date, the interest rate announced on the preceding Determination Date shall continue in effect. If for any reason the Variable Rate is not so determined for a second succeeding week or thereafter, the Variable Rate shall thereafter be determined by the Trustee and shall be a percentage per annum (not to exceed the Maximum Interest Rate) equal to twenty-five basis points in excess of the then current municipal swap index as quoted by the Bond Market Association.

     During the Variable Rate Period, the Borrower may provide for the conversion of the interest on all of the Project Bonds to a Fixed Interest Rate as provided in Section 4.01 hereof.

     During the Variable Rate Period, each Bond is required to be purchased on demand made by the Owner thereof upon the terms and conditions, including presentment of such Bond at the office of the Tender Agent, as specified in Section 3.02 hereof and the Notice of Demand Privilege as set forth in Exhibit A attached hereto.

     After conversion to a Fixed Interest Rate, the Project Bonds shall bear interest payable semi-annually on each Interest Payment Date, with such interest being initially paid on the first April 1 or October 1 after conversion to a Fixed Interest Rate, computed on the basis of a 360-day year of twelve 30-day months.

     Each Bond is subject to mandatory tender to the Tender Agent as specified in Section 3.01B, 3.03 and the Notice of Demand Privilege appearing in Exhibit A attached hereto in the City of Portland, Oregon, for purchase at a price equal to the principal amount thereof plus interest accrued thereon from the most recent Interest Payment Date therefor to the date of purchase specified below, unless sooner purchased on such terms pursuant to remarketing in accordance with the Remarketing Agreement, (1) on the Conversion Date when converted to a different Interest Rate Mode, and (2) on the last Interest Payment Date prior to the release of either the Letter of Credit or any Confirming Letter of Credit (in connection with a substitution of the Letter of Credit or any Confirming Letter of Credit, as the case may be, then in effect)..

     The principal of the Project Bonds shall be payable in lawful money of the United States of America at the Principal Office of the Paying Agent or its successor upon presentation of the Project Bonds. Payment of interest on the Project Bonds shall be made in lawful money of the United States of America to the Owner thereof by check or draft mailed to the Owner by the Paying Agent at his address as it appears on the registration books maintained by or on behalf of the Issuer on the Record Date, or at such other address as is furnished to the Paying Agent in writing by such Owner. Payment of interest on the Project Bonds may, at the option of any Owner of Project Bonds in an aggregate principal amount of at least $1,000,000, be transmitted by wire transfer to such Owner to the bank account number on file with the Registrar as of the Record Date or, when applicable, the Special Record Date.

     Section 2.02. Interest on Bonds .

     The Bonds shall bear interest from and including the date thereof until payment of the principal or redemption price thereof shall have been made or provided for in accordance with the provisions hereof, whether at maturity, upon redemption or otherwise. Interest accrued on the Bonds from the date of authentication to and including January 3, 2007 shall be paid on the first Thursday of January, 2007 at the Variable Rate. Thereafter until the Conversion Date, interest accrued on the Bonds during each Interest Period (calculated and determined for each Accrual Period) shall be paid on each Interest Payment Date and (except as otherwise provided in Section 4.06 hereof following conversion to a Fixed Interest Rate) computed on the basis of a year of 365 or 366 days, as appropriate, for the actual number of days elapsed. In no event shall the Variable Rate exceed the Maximum Interest Rate.

     Section 2.03. Execution . The Bonds shall be executed on behalf of the Issuer by the manual or facsimile signature of the Executive, attested by the manual or facsimile signature of the Secretary, and the Issuer’s corporate seal may be affixed, imprinted or reproduced thereon. All authorized facsimile signatures shall have the same force and effect as if manually signed. In case any official whose signature or a facsimile of whose signature shall appear on the Bonds shall cease to be such official before the delivery of such Bonds, such signature or such facsimile shall nevertheless be valid and sufficient for all purposes, the same as if such official had remained in office until delivery.

     No covenant, provision or agreement of the Issuer herein or in the Bonds or in any other document executed by the Issuer in connection with the issuance, sale and delivery of the Bonds, or any obligation herein or therein imposed upon the Issuer or breach thereof, shall give rise to a pecuniary liability of the Issuer, its members, officers, employees or agents or a charge against the Issuer’s general credit or general fund or shall obligate the Issuer, its members, officers, employees or agents financially in any way except with respect to this Indenture and the application of revenues therefrom and the proceeds of the Bonds. No failure of the Issuer to comply with any term, condition, covenant or agreement therein shall subject the Issuer, its members, officers, employees or agents to liability for any claim for damages, costs or other financial or pecuniary charges except to the extent that the same can be paid or recovered from this Indenture or revenues therefrom or proceeds of the Bonds. No execution on any claim, demand, cause of action or judgment shall be levied upon or collected form the general credit or general fund of the Issuer. In making the agreements, provisions and covenants set forth herein, the Issuer has not obligated itself except with respect to this Indenture and the application of revenues hereunder as hereinabove provided. The Bonds constitute special limited obligations of the Issuer, payable solely from the revenues pledged to the payment thereof pursuant to this Indenture and the Agreement, and do not now and shall never constitute an indebtedness or a loan of the credit of the Issuer, the State of Georgia or any political subdivision thereof or a charge against general taxing powers within the meaning of any constitutional or statutory provision whatsoever. It is further understood and agreed by the Borrower and the Holders that the Issuer, its members, officers, employees, or agents shall incur no pecuniary liability hereunder and shall not be liable for any expenses related hereto, all of which the Borrower agrees to pay. If, notwithstanding the provisions of this Section, the Issuer, its members, officers, employees or agents incur any expense, or suffer any losses, claims or damages or incur any liabilities, the Borrower will indemnify and hold harmless the Issuer, its members, officers, employees or agents from the same and will reimburse the Issuer, its members, officers, employees or agents in relation thereto, and this covenant to indemnify, hold harmless and reimburse the Issuer, its members, officers, employees or agents survives delivery of and payment for the Bonds.

     Section 2.04. Authentication . No Bond shall be valid or obligatory for any purpose or entitled to any security or benefit under this Indenture unless and until a certificate of authentication on such Bond substantially in the form set forth on Exhibit A hereto shall have been duly executed by the Trustee, and such executed certificate of the Trustee by a duly authorized signatory 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 manually signed by an authorized signatory of the Trustee, but it shall not be necessary that the same signatory sign the certificate of authentication on all of the Bonds issued hereunder. The Trustee shall insert the date of authentication of each Bond in the place provided for such purpose in the form of certificate of authentication of the Trustee to appear on each Bond.

     Section 2.05. Form of Bonds . The Bonds issued under this Indenture shall be substantially in the form set forth on Exhibit A hereto with, in the case of Additional Bonds, such omissions, insertions and variations as may be authorized or permitted by the Bond Resolution authorizing, or supplemental indenture entered into in connection with, such Additional Bonds, all consistent with this Indenture.

     Section 2.06. Delivery of Project Bonds . Upon the execution and delivery of this Indenture, the Issuer shall execute and deliver to the Trustee and the Trustee shall authenticate the Project Bonds and deliver them to or on behalf of the Underwriter as directed by the Issuer as hereinafter in this Section provided.

     2. The Letter of Credit and the Confirming Letter of Credit.

     3. Original executed counterparts of this Indenture and the Agreement.

     (e) require all payments on such Note to be made on or prior to the date for the corresponding payments to be made on the Project Bonds;

     (f) contain optional prepayment provisions and provisions in respect of the acceleration of principal and any premium corresponding to such provisions of the Project Bonds;

     (g) be on a parity with all other Notes thereafter executed and delivered by the Borrower.

     5. A request and authorization to the Trustee on behalf of the Issuer to authenticate and deliver the Project Bonds to or as directed by the Underwriter upon payment to the Trustee, but for the account of the Issuer, of a sum specified in such request and authorization.

     6. An opinion of Bond Counsel substantially to the effect that the Project Bonds constitute legal, valid and binding limited obligations of the Issuer, enforceable in accordance with their terms, subject to bankruptcy, insolvency, moratorium, reorganization and other similar laws affecting the rights of creditors and to the exercise of judicial discretion in accordance with general principles of equity; and

     7. Opinion of counsel to the Borrower in form and substance reasonably satisfactory to the Trustee, Bond Counsel, the Bank and the Underwriter.

     Section 2.07. 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 of like denomination as that mutilated, lost, stolen or destroyed; provided that, in the case of any mutilated Bond, such mutilated Bond shall first be surrendered to the Issuer and in the case of any lost, stolen or destroyed Bond, there shall be first furnished to the Issuer and the Trustee and the Borrower evidence of such loss, theft or destruction satisfactory to the Issuer, the Trustee and the Borrower, together with any indemnity satisfactory to them. In the event any such Bond

shall have matured, instead of issuing a duplicate Bond, the Issuer may pay the same without surrender thereof. The Issuer and the Trustee may charge the owner of such Bond with their reasonable fees and expenses in this connection.

     B. In the event that any Bond to be purchased pursuant to Section 3.09 hereof is not delivered by the Owner thereof on the date such Bond is to be purchased, the Issuer shall execute and the Authenticating Agent shall authenticate and deliver a new Bond of like date, maturity and denomination as the Bond to be purchased, and the Registrar shall register such Bond in the name of the new Owner.

     Section 2.08. Registration and Exchange of Bonds; Persons Treated as Owners . The Issuer shall cause books for the registration and for the transfer of the Bonds as provided in this Indenture to be kept by the Trustee which is hereby constituted and appointed the Registrar of the Issuer.

     Upon surrender for transfer of any Bond at the designated corporate trust office of the Trustee, duly endorsed for transfer or accompanied by an assignment duly executed by the registered owner or his attorney duly authorized in writing, the Trustee shall authenticate and deliver in the name of the transferee or transferees a new Bond or Bonds duly executed by the Issuer of an Authorized Denomination or Authorized Denominations for a like aggregate principal amount.

     Any Bond or Bonds may be exchanged at the designated corporate trust office of the Trustee for a new Bond or Bonds of like principal amount of another Authorized Denomination or other Authorized Denominations. Upon surrender of any Bond or Bonds for exchange, the Trustee shall authenticate and deliver a new Bond or Bonds duly executed by the Issuer which the Bondholder making the exchange is entitled to receive.

     The Trustee shall not be required to transfer or exchange any Bond during the period of fifteen (15) days next preceding any Interest Payment Date nor to transfer or exchange any Bond after the mailing of notice calling such Bond or portion thereof for redemption has been given as herein provided, nor during the period of fifteen (15) days next preceding the giving of such notice of redemption.

     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 premium, if any, or interest on any such Bond shall be made only to or upon the written order of the registered owner thereof or his legal representative, but such registration may be changed as hereinabove provided. All such payments shall be valid and effectual to satisfy and discharge the liability upon such Bond to the extent of the sum or sums so paid.

     In each case the Trustee shall require the payment by the Bondholder requesting exchange or transfer of any tax or other governmental charge required to be paid with respect to such exchange or transfer, but otherwise no charge shall be made to the Bondholder for such exchange or transfer.

     Section 2.09. Cancellation of Bonds . Whenever any outstanding Bond shall be delivered to the Trustee for cancellation pursuant to this Indenture, upon payment of the principal amount represented thereby, or for replacement pursuant to Section 2.07, or for transfer pursuant to Section 2.08, such Bond shall be promptly canceled and destroyed by the Trustee.

     Section 2.10. Book Entry System . The Project Bonds shall be initially issued in the name of “Cede & Co.,” as nominee for The Depository Trust Company (“DTC”), as registered owner of the Project Bonds, and held in the custody of DTC. A single Bond certificate will be issued and delivered to DTC. The actual purchasers of the Project Bonds (the “Beneficial Owners”) will not receive physical delivery of Bond certificates except as provided herein. For so long as DTC shall continue to serve as

securities depository for the Project Bonds as provided herein, all transfers of beneficial ownership interests will be made by book-entry only, and no investor or other party purchasing, selling or otherwise transferring beneficial ownership of Project Bonds is to receive, hold or deliver any Bond certificate.

     For every transfer and exchange of Bonds, the Beneficial Owner may be charged a sum sufficient to cover such Beneficial Owner’s allocable share of any tax, fee or other governmental charge that may be imposed in relation thereto.

     Bond certificates are required to be delivered to and registered in the name of the Beneficial Owner under the following circumstances:

     (a) DTC determines to discontinue providing its service with respect to the Bonds. Such a determination may be made at any time by giving 30 days’ notice to the Issuer, the Borrower and the Trustee and discharging its responsibilities with respect thereto under any applicable law; or

     (b) the Borrower determines to discontinue the system of book-entry transfers through DTC (or a successor securities depository).

     The Issuer, the Borrower and the Trustee will recognize DTC or its nominee as the Bond owner for all purposes, including notices and voting.

     The Issuer, the Trustee and the Underwriter may conclusively rely on (A) a certificate of DTC as to the identity of the participants in the book-entry system, and (B) a certificate of such participants as to the identity of, and the respective principal amounts of Bonds beneficially owned by, the Beneficial Owners.

     Whenever, during the term of the Bonds, beneficial ownership thereof is determined by a book entry at DTC, the requirements in this Indenture of holding, delivering or transferring Bonds shall be deemed modified to require the appropriate person to meet the requirements of DTC as to registering or transferring the book entry to produce the same effect.

     The Trustee and the Issuer, at the direction and expense of the Borrower and with the written consent of the Underwriter, may from time to time appoint a successor securities depository and enter into an agreement with such successor securities depository, to establish procedures with respect to the Bonds not inconsistent with the provisions of this Indenture. Any successor securities depository shall be a “clearing agency” registered under Section 17A of the Securities Exchange Act of 1934, as amended.

     Neither the Issuer, the Borrower, the Trustee nor the Underwriter (except and only to the extent it is also a participant in the book-entry system) will have any responsibility or obligation to DTC, any participant in the book-entry system or the Beneficial Owners with respect to (i) the accuracy of any records maintained by DTC or any participant, (ii) the payment by DTC or any participant of any amount due to any Beneficial Owner with respect to the principal or purchase price or, the premium or interest on, any Bond, (iii) the delivery of any notice by DTC or any participant, (iv) the selection of the Beneficial Owners to receive payment in the event of any partial redemption of the Bonds, or (v) any other action taken by DTC or any participant.

     Notwithstanding anything in this Indenture to the contrary, the Issuer and the Trustee hereby agree as follows with respect to the Bonds, if and to the extent any Bond is registered in the name of “Cede & Co.” as nominee of DTC: (i) the Trustee shall give DTC all special notices required by the Representation Letter at the times, in the forms and by the means required by the Representation Letter; (ii) the Trustee shall make payments to Cede & Co. at the times and by the means specified in the Representations Letter; (iii) Cede & Co., shall not be required to surrender Bonds which have been

partially paid or prepaid to the extent permitted by the Representation Letter; and (iv) the Trustee shall set a special record date (and shall notify the registered owners of the Bonds thereof in writing) prior to soliciting any Bondholder consent or vote, such notice to be given not less than 15 calendar days prior to such record date (any Bond transferred by a registered owner subsequent to the establishment of the special record date and prior to obtaining such consent or vote shall have attached to it a copy of the notice to Bondholders by the Trustee).

     If at any time DTC ceases to hold the Bonds, all references herein to DTC shall be of no further force and effect.

     Section 2.11 Issuance of Additional Bonds . At the request of the Borrower, the Issuer may issue Additional Bonds from time to time for any purpose permitted by the Act.

          Those Additional Bonds shall be on a parity with the Project Bonds and any Additional Bonds theretofore or thereafter issued and outstanding as to the assignment to the Trustee of the Issuer’s right, title and interest in the Agreement, the Project Fund and the Bond Fund and the moneys and investments therein to provide for payment of principal of, and premium, if any, and interest on the Project Bonds; provided, that nothing herein shall prevent payment of principal of, and premium, if any, and interest on any series of Additional Bonds from (i) being otherwise secured and protected from sources or by property or instruments not applicable to the Project Bonds and any one or more series of Additional Bonds, or (ii) not being secured or protected from sources or by property or instruments applicable to the Project Bonds or one or more series of Additional Bonds. Each series of Additional Bonds shall be given a separate designation to distinguish it from any other series of Bonds issued hereunder, and any Supplemental Indenture entered into in connection with a series of Additional Bonds shall establish a separate Reimbursement Account with respect to that series, in which shall be deposited the proceeds of the drawings on the additional letter of credit securing such series, and which Reimbursement Account shall not be pledged to or constitute part of the security for the payment of principal of, and premium, if any, and interest on any other series of Bonds.

     Section 2.12 Delivery of Additional Bonds . Before any Additional Bonds shall be authenticated and delivered by the Trustee, there shall be filed with the Trustee the following items:

     1. A copy, duly certified by the Secretary or Assistant Secretary of the Issuer, of the proceedings of the Issuer authorizing the execution and delivery of any amendments to the Agreement, the Note, this Indenture, and the Bond Purchase Agreement, and the issuance of the Additional Bonds.

     2. An original executed letter of credit and the confirming letter of credit.

     3. Original executed counterparts of any amendments to this Indenture and the Agreement.

     4. The original executed additional Note or Notes with such variations in principal amounts, interest rates, interest payment and maturity dates and prepayment provisions as may be appropriate to correspond to such provisions of the Additional Bonds, which Note or Notes will:

     (a) be payable to the Issuer and assigned to the Trustee;

     (b) be issued in an aggregate principal amount equal to the aggregate principal amount of the Additional Bonds;

     (c) provide for payments of interest equal to the payments of interest on the Additional Bonds;

     (d) require payments of principal, any premium and/or prepayments equal to the payments of principal, any premium and/or sinking fund payments on the Additional Bonds;

     (e) require all payments on such additional Note or Notes to be made on or prior to the date for the corresponding payments to be made on the Additional Bonds;

     (f) contain optional prepayment provisions and provisions in respect of the acceleration of principal and any premium corresponding to such provisions of the Additional Bonds; and

     (g) be on a parity with all other Notes before or after executed and delivered by the Borrower pursuant to the Agreement corresponding to any Bonds.

     5. A request and authorization to the Trustee on behalf of the Issuer to authenticate and deliver the Additional Bonds to or as directed by the purchaser thereof upon payment to the Trustee, but for the account of the Issuer, of a sum specified in such request and authorization.

     6. An opinion of Bond Counsel substantially to the effect that the Additional Bonds constitute legal, valid and binding limited obligations of the Issuer, enforceable in accordance with their terms, subject to bankruptcy, insolvency, moratorium, reorganization and other similar laws affecting the rights of creditors and to the exercise of judicial discretion in accordance with general principles of equity; and

     7. Opinion of counsel to the Borrower in form and substance reasonably satisfactory to the Trustee, Bond Counsel and the Underwriter.

     8. The consent of the Bank, which shall not be unreasonably withheld.

     The Trustee, the Tender Agent and the Remarketing Agent shall hold all money delivered to the Trustee, the Tender Agent or the Remarketing Agent, respectively, hereunder for the purchase of Bonds in trust solely for the benefit of the respective Persons that shall have so delivered such money until the Bonds purchased with such money are delivered pursuant to Section 3.05 and, thereafter, in the order specified above, for the benefit of the Owners tendering such Bonds.

     Section 3.05 Disposition of Tendered Bonds.

     A. Bonds tendered or deemed tendered pursuant to Section 3.02 or Section 3.03, the Purchase Price for which has been paid pursuant to Section 3.04, shall be deemed to have been purchased:

     (1) by the Persons to whom Bonds have been remarketed to the extent the Purchase Price therefor is paid from proceeds from the remarketing thereof pursuant to Section 3.04.

     (2) by the Borrower as pledgor for the benefit of the Bank or the Confirming Bank, respectively, as pledgee to the extent the Purchase Price therefor is paid from amounts drawn under or derived from the Letter of Credit pursuant to Section 3.04A or any Confirming Letter of Credit pursuant to Section 3.04B, and

     (3) otherwise by the Borrower.

     All Bonds purchased with proceeds made available through the Letter of Credit or any Confirming Letter of Credit pursuant to this Section shall constitute “Pledged Bonds,” and shall be delivered to and held by the Trustee as agent for the Bank or any Confirming Bank, as applicable (and shall be shown as Pledged Bonds on the bond register), in accordance with the terms and provisions of this Indenture and the Reimbursement Agreement. All payments on such Pledged Bonds shall be paid to the Bank. The Remarketing Agent shall at the request of the Bank or any Confirming Bank continue to use its best efforts to arrange for the sale of any Pledged Bonds at the purchase price, subject to full reinstatement of the amount available to be drawn under the Letter of Credit with respect to such Bonds to an amount equal to the principal amount of such Bonds plus the amount required for premium and interest thereon.

     If the Remarketing Agent remarkets any Pledged Bonds, the Remarketing Agent shall direct the purchaser of such Pledged Bond to transfer, by 10:00 a.m., Portland, Oregon time, on the purchase date, the purchase price of such remarketed Pledged Bond in immediately available funds to the Tender Agent, to be disbursed from such account solely for the purposes described in this paragraph. The Tender Agent shall immediately notify either the Bank or the Confirming Bank, as applicable (depending upon whether the purchase proceeds were made available through a draw on the Letter of Credit or a Confirming Letter of Credit), and the Remarketing Agent and the Trustee of the receipt of the purchase price for such Pledged Bond, and upon receipt of the purchase price and written notice from the Bank, to the Trustee of full reinstatement of the amount available to be drawn under the Letter of Credit or Confirming Letter of Credit, as applicable, with respect to such remarketed Pledged Bonds (as contemplated by the proceeding paragraph), such Pledged Bond shall be released from the pledge of the Bank or Confirming Bank, as the case may be. The Trustee shall transfer such purchase price to the Bank or Confirming Bank, as the case may be, upon receipt thereof and of evidence satisfactory to the Trustee of full reinstatement of the amount available to be drawn under the Letter of Credit or Confirming Letter of Credit with respect to such remarketed Pledged Bonds (as contemplated by the preceding paragraph) to the extent that amounts remain due and owing to either the Bank under the Letter of Credit or the Confirming Bank under the Confirming Letter of Credit, and give all required notices, in accordance with the terms of the Letter of Credit or the Confirming Letter of Credit, as the case may be. If money remains on deposit with the Tender Agent after payment is made to the Bank or Confirming Bank, as described in the proceeding sentence, such moneys shall be paid to, or upon the order of, the Borrower.

     Notwithstanding anything to the contrary in this subsection, if and for so long as the Bonds are held in book entry form, the registration requirements under this subsection shall be deemed satisfied if Pledged Bonds are (A) registered in the name of the securities depository or its nominee, (B) credited on the books of the securities depository to the account of the Trustee (or its nominee) and (C) further credited on the books of the Trustee (or such nominee) to the account of the Bank (or its designee).

     B. Whenever any Bond tendered or deemed tendered pursuant to Section 3.01 or Section 3.03 is purchased pursuant to Sections 3.04 and 3.05A, the Issuer shall execute, and the Authenticating Agent shall authenticate and deliver, in the name of the Person that purchased or that is deemed to have purchased the same or its designee, one or more new Bonds bearing interest at a Variable Rate or a Fixed Interest Rate, as appropriate, of any authorized denomination and of a like aggregate principal amount pursuant hereto.

     C. The Tender Agent shall hold all Bonds delivered to such Person hereunder solely for the benefit of the respective Owners which have so delivered such Bonds until money representing the Purchase Price of such Bonds shall have been delivered to or for the account of or to the order of such Owners and, in the case of Bonds pledged to or held in the name of the Bank, for the benefit of the Bank until disposed of pursuant to instructions from the Bank.

     D. In carrying out their respective responsibilities under this Article, the Remarketing Agent, the Tender Agent and the Paying Agent shall be acting solely as the agent of the Owners from time to time of the Bonds tendered or deemed tendered and of the Persons purchasing the same pursuant to Sections 3.04 and 3.05A, respectively. No delivery of Bonds to the Tender Agent pursuant hereto shall constitute a redemption of Bonds or other extinguishment of the debt evidenced thereby.

     Section 3.06. No Purchases or Sales After Certain Defaults . Anything in this Indenture to the contrary notwithstanding, there shall be no purchases of Bonds with moneys in the Bond Fund or sales of Bonds pursuant to Sections 3.01, 3.02, 3.03 or 3.04 if there shall have occurred and be continuing an

Event of Default hereunder, other than an Event of Default described in paragraphs (d), (e), (f), (g) or (h) of Section 9.01 hereof.

     Section 3.07. Mandatory Redemption of Bonds .

     A. The Project Bonds shall be subject to mandatory redemption in whole (or, in the case of the event stated in (2) of this paragraph, in whole or in part as provided below), at a redemption price equal to 100% of the principal amount thereof, plus accrued interest, if any, to the redemption date, on any Business Day within 180 days after the occurrence of either of the following events:

     (1) As a result of any changes in the Constitution of the State or the Constitution of the United States of America or of legislative or administrative action (whether state or federal) or by final decree, judgment or order of any court or administrative body (whether state or federal) entered after the contest thereof by the Borrower in good faith, the Note shall have become void or unenforceable or impossible of performance in accordance with the intent and purposes of the parties as expressed in the Agreement; or

     (2) [Reserved].

     B. [Reserved].

     C. The Bonds are subject to mandatory redemption in whole on any Interest Payment Date which next precedes either a Letter of Credit Termination Date or the expiration date of the Confirming Letter of Credit, or a subsequent date to which the Letter of Credit Termination Date or the expiration date of the Confirming Letter of Credit, respectively, shall have been extended (or if the Letter of Credit Termination Date or the expiration date of the Confirming Letter of Credit is on an Interest Payment Date, then such date), at a redemption price of 100% of the principal amount thereof plus accrued interest to the redemption date unless, at least forty-five (45) days prior to any such Interest Payment Date (a) the Bank and/or Confirming Bank, as the case may be, shall have extended or further extended the Letter of Credit Termination Date or the expiration date of the Confirming Letter of Credit, as the case may be, to a date not earlier than one (1) year from the Letter of Credit Termination Date or Confirming Letter of Credit expiration date being extended or (b) the Borrower shall have obtained an Alternate Letter of Credit or Alternate Confirming Letter of Credit with a termination date not earlier than one (1) year from the Letter of Credit Termination Date or Confirming Letter of Credit expiration date for the Letter of Credit or Confirming Letter of Credit, as the case may be, it replaces. If the Bonds are then rated by either Moody’s or S&P, the Trustee shall promptly notify such rating agency in writing of any such extension of a Letter of Credit Expiration Date or the expiration date of any Confirming Letter of Credit.

     D. The Bonds shall be subject to mandatory redemption by the Issuer, as a whole or in part, at a redemption price of 100% of the principal amount thereof plus accrued interest, if any, to the redemption date, on any date within one hundred and eighty (180) days after the Completion Date with and to the extent of any excess proceeds of the Bonds, including income from the investment thereof, which shall remain in the Project Fund after completion of the Project and the payment of the Project Costs. Upon the occurrence of the event stated in this Section 3.07D, the principal amount of the Bonds to be redeemed will be a principal amount equal to the lowest integral multiple of $5,000 (provided that the unredeemed portion of any Bond redeemed in part shall be $100,000 or more), equal to or in excess of the remaining proceeds of the Bonds, including income from the investment thereof.

     Section 3.08. Optional Redemption .

     A. Prior to conversion to the Fixed Interest Rate, the Bonds shall be subject to optional redemption by the Issuer in whole or in part in integral multiples of $5,000 (provided that the unredeemed portion of any Bond redeemed in part shall be $100,000 or more), at the direction of the Borrower, on any Interest Payment Date, at the principal amount thereof without premium or penalty. Notwithstanding the provisions of Section 6.04 hereof, while the Letter of Credit is in effect with respect to the Bonds, the redemption price to be paid pursuant to this paragraph shall be derived solely from Available Moneys or, with the prior written consent of the Bank, which may be granted or denied in its sole and absolute discretion, moneys received from a drawing under the Letter of Credit.

     B. From and after conversion to the Fixed Interest Rate through the Maturity Date (the “Fixed Rate Period”), the Bonds shall be subject to optional redemption by the Issuer in whole or in part in the amount of $5,000 or any integral multiples thereof (provided that the unredeemed portion of any Bond redeemed in part shall be $100,000 or more), at the direction of the Borrower, on any Interest Payment Date, as follows: (1) no Bonds shall be subject to such optional redemption prior to the first Redemption Year which shall commence on the October 1 next preceding the midpoint of the Fixed Rate Period (unless such midpoint is October 1 of any year, in which case the Redemption Year shall commence on such April 1); (2) during such first Redemption Year, Bonds may be redeemed at a redemption price of 102% of their principal amount, plus accrued interest to the redemption date; (3) thereafter, during the Redemption Year next following Bonds may be redeemed at a redemption price of 101% of their principal amount, plus accrued interest to the redemption date; and (4) thereafter, until and including the next succeeding Mandatory Tender Date (or final maturity, if earlier) of such Series, such Bonds may be redeemed at a redemption price equal to their principal amount, plus accrued interest to the redemption date. Notwithstanding the foregoing, Bonds may be redeemed on any Mandatory Tender Date at a redemption price equal to their principal amount plus accrued interest to the redemption date.

     C. The Bonds shall be subject to optional redemption in whole by the Issuer, but not in part, on any Business Day, at a redemption price equal to 100% of the principal amount thereof plus accrued interest, if any, to the redemption date, upon the exercise by the Borrower of its option to prepay payments under Section 8.2 of the Agreement, if any of the following shall have occurred:

     (1) All or substantially all of the Project shall be damaged or destroyed and the Borrower shall determine that it is not practicable or desirable to rebuild, repair or restore the Project;

     (2) All or substantially all of the Project shall be condemned or such use or control thereof shall be taken as to render the Project unsatisfactory to the Borrower for continued operation; or

     (3) Unreasonable burdens or excessive liabilities shall be imposed upon the Issuer or the Borrower with respect to the Project or the operation thereof.

While the Letter of Credit or an Alternate Letter of Credit is in effect with respect to the Bonds, the redemption price to be paid pursuant to this paragraph shall be derived solely from Available Moneys or, with the prior written consent of the Bank, which consent may be granted or denied in its sole and absolute discretion, moneys received from a drawing under the Letter of Credit or from moneys paid under the Alternate Letter of Credit.

     Section 3.09. Purchase of Bonds Upon Conversion to Fixed Interest Rate or Upon Release of the Letter of Credit .

     A. In the event that Bonds are subject to mandatory tender for purchase in accordance with Section 3.03B(1) or Section 3.03B(2), the Borrower shall, with the prior written consent of the Bank,

have the right to direct the Trustee to purchase, or cause to be purchased for cancellation, Bonds in an aggregate principal amount specified in a written direction delivered to the Trustee on or before the Interest Payment Date on which such Bonds are to be purchased pursuant to Section 3.03B hereof, such Bonds to be purchased at a price of 100% of the principal amount thereof plus accrued interest to the date of such purchase. Moneys for the payment of such purchase price shall be derived solely from Available Moneys provided by the Borrower and on deposit with the Trustee in a special trust account of the Bond Fund on the date of such purchase or from moneys drawn under the Letter of Credit or an Alternate Letter of Credit.

     B. Bonds to be purchased as provided in paragraph A above which are not delivered by the Owners thereof to the Tender Agent on the Interest Payment Date on which such Bonds are to be tendered pursuant to Section 3.03B(1) or 3.03B(2) hereof shall nonetheless be deemed to have been delivered by the Owner thereof for purchase and to have been purchased from funds described in paragraph A above. Thereafter, the Trustee or the Authenticating Agent shall authenticate (and the Issuer execute, if necessary) a new Bond as provided in Section 2.08B hereof. Accrued interest payable to the date of purchase of Bonds purchased as provided in this Section 3.09 shall be paid to the Owner as of the Record Date next preceding the date of purchase of such Bond in the same manner as if such Bonds were not purchased pursuant to paragraph A above. Moneys deposited with the Paying Agent for purchase of Bonds pursuant to this Section 3.09 shall be held in trust in a separate escrow account, shall not be invested by the Paying Agent and shall be paid to the former Owners of such Bonds upon presentation thereof. The Paying Agent shall promptly give notice by Mail to each Owner whose Bonds are deemed to have been purchased pursuant to this Section 3.09, which notice shall state that interest on such Bonds ceased to accrue on the date of purchase and that moneys representing the purchase price of such Bonds are available against delivery thereof at the principal office of the Paying Agent. The Paying Agent shall hold moneys deposited by the Borrower or drawn by the Trustee under the Letter of Credit or Alternate Letter of Credit for the purchase of Bonds as provided in this Section 3.09, without liability for interest thereon, for the benefit of the former Owner of the Bond on such Interest Payment Date, who shall thereafter be restricted exclusively to such moneys, for any claim of whatever nature on his part under this Indenture or on, or with respect to, such Bond. Any moneys so deposited with and held by the Paying Agent not so applied to the payment of Bonds, if any, within two (2) years after such Interest Payment Date, shall be paid by the Paying Agent to the Borrower upon the written direction of an Authorized Borrower Representative (or, if the Bank shall have given written notice to the Paying Agent of the existence of a breach of the Borrower’s obligations under the Reimbursement Agreement, to the Bank to the extent of such amount) and thereafter the former Owners shall be entitled to look only to the Borrower for payment, and then only to the extent of the amount so repaid, and the Borrower shall not be liable for any interest thereon and shall not be regarded as a trustee of such money.

     Section 3.10. Selection of Bonds to be Redeemed . If less than all of the Bonds are called for redemption, the Trustee shall select the Bonds or portions thereof in the amount of $5,000 or any integral multiple thereof (provided, however, that the unredeemed portion of any Bond redeemed in part shall be $100,000 or more) to be redeemed from the Bonds outstanding not previously called for redemption by lot in such manner as the Trustee in its discretion may deem proper, and each $5,000 of face value of each Bond shall be treated as a separate Bond for the purpose of selection by lot. If it is determined that a portion but not all of the principal amount of any Bond is to be called for redemption, then, upon notice of intention to redeem such portion, the owner of such Bond shall surrender such Bond to the Trustee for (a) payment to such owner of the redemption price of the portion of principal amount called for redemption, and (b) delivery to such owner of a new Bond or Bonds in the aggregate principal amount of the unredeemed portion of the principal amount of such Bond. New Bonds representing the unredeemed portion of the principal amount of such Bond shall be issued to the owner thereof without charge therefor. If the owner of any such Bond shall fail to present such Bond to the Trustee for payment and exchange as aforesaid, such Bond shall, nevertheless, become due and payable on the date fixed for redemption to the

extent of the portion of principal amount called for redemption (and to that extent only) and interest with respect to such portion will cease to accrue provided that funds for the redemption thereof are on deposit with the Trustee at that time.

     Anything herein to the contrary notwithstanding, Pledged Bonds, as defined in the Reimbursement Agreement, shall so long as the Bank is not in default with respect to its obligations under the Letter of Credit, be redeemed prior to any other Outstanding Bonds.

     Section 3.11. Notice of Redemption .

     A. In the event any of the Bonds are called for redemption, the Trustee shall give notice, in the name of the Issuer, of the redemption of such Bonds, which notice shall (i) specify the Bonds to be redeemed, the redemption date, the redemption price and the place or places where amounts due upon such redemption will be payable (which shall be the principal office of the Paying Agent) and, if less than all of the Bonds are to be redeemed, the numbers of the Bonds, and the portions of Bonds, so to be redeemed, (ii) state any condition to such redemption and (iii) state that on the redemption date and upon the satisfaction of any such condition, the Bonds to be redeemed shall cease to bear interest. Such notice may set forth any additional information relating to such redemption. Such notice shall be given by Mail at least thirty (30) days prior to the date fixed for redemption to the Owners of Bonds to be redeemed and, if all the Bonds are to be redeemed and the Bonds are then rated by Moody’s or S&P, to Moody’s or S&P, to such agency, and, during the Variable Rate Period, the Remarketing Agent; provided, however, that if a Bond delivered pursuant to Section 3.05 hereof on or after the Special Record Date established for a proposed redemption of Bonds shall be deemed to have been selected for redemption pursuant to Section 3.10 hereof, such notice shall be given by telephone or telecopy, confirmed in writing, as promptly as practicable. Provided, however, that failure to duly give such notice, or any defect therein, shall not affect the validity of any proceedings for the redemption of Bonds with respect to which no such failure or defect occurred. In addition, the Trustee may give such other notice or notices as may be recommended in releases, letters, pronouncements or other writings of the Securities and Exchange Commission and the Municipal Securities Rulemaking Board. No defect in or delay or failure in giving any recommended notice described in the preceding sentence of this Section 3.11 shall in any manner affect the notice of redemption described in the first sentence of this Section 3.11. Any notice mailed as provided in this Section shall be conclusively presumed to have been duly given, whether or not the owner receives the notice. If a notice of redemption shall be unconditional, or if the conditions of a conditional notice of redemption shall have been satisfied, then upon presentation and surrender of Bonds so called for redemption at the place or places of payment, such Bonds shall be redeemed.

     B. [Reserved]

     C. Any Bonds which have been duly selected for redemption and which are deemed to be paid in accordance with Article VIII hereof shall cease to bear interest on the specified redemption date.

     Section 3.12. No Partial Redemption After Default . Anything in this Indenture to the contrary notwithstanding, if there shall have occurred and be continuing an Event of Default (other than an Event of Default described in clause (f) of Section 9.01 hereof), there shall be no redemption of less than all of the Bonds at the time Outstanding.

     Section 3.13. Payment of Redemption Price . For the redemption of any of the Bonds, the Issuer shall cause to be deposited in the Bond Fund, solely out of Available Moneys or drawings under the Letter of Credit or Alternate Letter of Credit, an amount sufficient to pay the principal of, premium, if any, and interest to become due on the date fixed for such redemption. The obligation of the Issuer to cause any such deposit to be made hereunder shall be reduced by the amount of Available Moneys or

moneys resulting from a drawing under the Letter of Credit in the Bond Fund available for and used on such redemption date for payment of the principal of, premium, if any, and accrued interest on the Bonds to be redeemed within the meaning of Article VIII hereof.

     Section 3.14. Partial Redemption of Bonds . In case a Bond is of a denomination larger than the minimum Authorized Denomination, all or a portion of such Bond may be redeemed in an Authorized Denomination. Upon surrender of any Bond for redemption in part only, the Trustee shall authenticate and deliver to the owner thereof, without cost to the owner, a new Bond or Bonds duly executed by the Issuer in Authorized Denominations in aggregate principal amount equal to the unredeemed portion of the Bond surrendered.

     Section 3.15. Notice by Tender Agent . The Tender Agent shall give Immediate Notice to the Remarketing Agent of (i) its receipt of any tendered Bonds, and (ii) the receipt of any Notice described in Section 3.03 hereof.

ARTICLE IV

CONVERSION TO FIXED INTEREST RATE

     Section 4.01. Authority for and Conditions to Conversion to Fixed Interest Rate . The interest rate borne by the Bonds shall be converted to the Fixed Interest Rate as follows:

     With the prior written consent of the Bank, which consent may be granted or denied in its sole and absolute discretion, upon receipt by the Trustee of an amendment to the Letter of Credit, or upon the delivery of an Alternate Letter of Credit, increasing the amount available to be drawn for the payment of accrued interest on the Bonds to two hundred (200) days of accrued interest on the then existing principal balance of the Bonds at the Fixed Interest Rate, on any Interest Payment Date (if such date is designated by the Borrower as the Conversion Date), the Borrower may elect to convert the rate on the Bonds to the Fixed Interest Rate through the Maturity Date. The Borrower may exercise its conversion option by giving the Trustee, the Bank, the Confirming Bank, the Paying Agent, the Tender Agent and the Remarketing Agent written notice of its intention to convert the rate to the Fixed Interest Rate, at least fifty (50) days prior to the proposed Conversion Date.

     If the Borrower elects to convert the interest rate as aforesaid, the Paying Agent shall notify each Bondholder in writing by Mail at least thirty (30) days prior to the Conversion Date of the fact that the rate will be converted, and that the Bondholder shall tender the Bonds for purchase by the Remarketing Agent prior to the Interest Payment Date which is the Conversion Date in accordance with the terms of the Bonds.

     Section 4.02 Determination of Fixed Interest Rate . On a day which is a Business Day at least seven (7) days prior to the Conversion Date (the “Rate Determination Date”), the Remarketing Agent shall determine the Fixed Interest Rate.

     The Remarketing Agent shall determine the Fixed Interest Rate on the Rate Determination Date to be that rate per annum which, if borne by all of the outstanding Bonds through the Maturity Date, would, in the judgment of the Remarketing Agent (taking into consideration current transactions and comparable securities in which the Remarketing Agent is involved or of which it is aware and prevailing financial market conditions), be the interest rate necessary (but which would not exceed the interest rate necessary) to produce as nearly as practical a par bid for each outstanding Bond on the Rate Determination Date.

     On the Rate Determination Date, the Remarketing Agent shall advise the Borrower, the Trustee and the Bank by telephone (to be confirmed in writing) of the Fixed Interest Rate.

     Section 4.03. Replacement Bonds . The Paying Agent, at the direction of the Borrower, shall deliver replacement Bonds bearing the Fixed Interest Rate with deletion of such terms as are no longer applicable. Any such replacement Bonds shall be executed and authenticated as provided in Sections 2.03 and 2.04 herein. Notwithstanding anything herein to the contrary, any replacement Bonds shall be in $5,000 denominations or integral multiples thereof.

     Section 4.04. Certain Provisions No Longer Applicable .

     A. The day after the effective date of the Fixed Interest Rate, the Bonds shall no longer be subject to the following provisions of this Indenture, and in the event of delivery of replacement Bonds pursuant to Section 4.03 hereof, any recital of such provisions shall be deleted from such replacement Bonds:

     (i) The provisions of Section 2.01 relating to computation of the Variable Rate;

     (ii) The provisions of Sections 3.01, 3.02, 3.03, 3.04, 3.05 and 3.06 relating to the purchase, remarketing and delivery of Bonds;

     (iii) Article IV relating to conversion to a Fixed Interest Rate, except this Section 4.04 and Section 4.05; and

     (iv) Sections 10.11, 10.12, 10.13 and 10.14 relating to the Remarketing Agent and the Tender Agent.

     Additionally, following conversion to the Fixed Interest Rate, all references herein and in the Agreement and the Note to the Remarketing Agent shall be of no further effect, except with respect to any unpaid fees or expenses of the Remarketing Agent and the indemnification provided in the Agreement.

     Section 4.05. Interest on Bonds After Conversion to Fixed Interest Rate . Following conversion to a Fixed Interest Rate, the Bonds shall bear interest at the Fixed Interest Rate, payable each April 1 and October 1, commencing on the first April 1 or October 1 following such conversion, computed on the basis of a year of 360 days and twelve 30-day months.
