The total aggregate principal amount of Bonds that may be issued and Outstanding under this Indenture is expressly limited to $22,000,000, exclusive of Bonds executed and authenticated as provided in Section 2.07 hereof; provided, however, that no Bonds shall be delivered hereunder until the Registrar receives a request and authorization of the Issuer signed by the Executive Officer to authenticate and deliver the principal amount of the Bonds therein specified to the purchaser or purchasers therein identified upon payment to the Trustee, for the account of the Issuer, of the sum specified in such request and authorization.

Section 2.02.

Date, Denomination, Interest Rate, and Maturity. (a) The Bonds shall be dated as of the Dated Date. The Bonds shall be issued as registered bonds without coupons. The Bonds shall be issued only in Authorized Denominations. The Bonds shall be numbered consecutively from R-1 upwards.

The Bonds shall mature on September 1, 2019 and bear interest at the rate of 7.50% per annum, payable on March 1 and September 1 of each year, commencing September 1, 2007. The Bonds shall bear interest from the Dated Date or from and including the most recent Interest Payment Date with respect to which interest has been paid or duly provided for. Interest shall be calculated on the basis of a 360-day year consisting of twelve 30-day months.

(b) Each Bond shall bear interest from the Interest Payment Date next preceding the date of registration and authentication thereof unless it is registered and authenticated on or prior to the first Interest Payment Date, in which event it shall bear interest from the Dated Date; provided, however, that if, as shown by the records of the Trustee, interest on the Bonds shall be in default, Bonds issued in exchange for Bonds surrendered for registration of transfer or exchange shall bear interest from the last date to which interest has been paid in full or duly provided for on the Bonds, or, if no interest has been paid or duly provided for on the Bonds, from the Dated Date. Payment of the interest on any Bond shall be made to the person appearing on the bond registration books of the Registrar as the registered Owner thereof on the Record Date (except that, if and to the extent that there shall be a default in the payment of the interest due on an Interest Payment Date, such defaulted interest shall be paid to the Owners in whose name any such Bonds are registered as of a special record date to be fixed by the Trustee, notice of which shall be given to such Owners not less than ten days prior thereto), such interest to be paid by the Trustee to such registered Owner, as follows:

(1)

in respect of any Bond which is registered in the book-entry system pursuant to Section 2.10 hereof, in immediately available funds by no later than 2:30 p.m., New York City time, and

14

Execution of Bonds. The Bonds shall be signed in the name and on behalf of the Issuer with the manual or facsimile signature of its Mayor and attested by the manual or facsimile signature of the Clerk-Treasurer. The Bonds shall then be delivered to the Registrar for authentication by it. In case any officer who shall have signed any of the Bonds shall cease to be such officer before the Bonds so signed or attested shall have been authenticated or delivered by the Registrar or issued by the Issuer, such Bonds may nevertheless be authenticated, delivered and issued and, upon such authentication, delivery and issuance, shall be as binding upon the Issuer as though those who signed and attested the same had continued to be such officers of the Issuer. Also, any Bond may be signed on behalf of the Issuer by such persons as on the actual date of the execution of such Bond shall be the proper officers although on the nominal date of such Bond any such person shall not have been such officer.

Only such of the Bonds as shall bear thereon a certificate of authentication in the form set forth in Exhibit A hereto, manually executed by an authorized signatory of the Registrar, shall be valid or obligatory for any purpose or entitled to the benefits of this Indenture, and such certificate of the Registrar shall be conclusive evidence that the Bonds so authenticated have been duly authenticated and delivered hereunder and are entitled to the benefits of this Indenture. Upon authentication of any Bond, the Registrar shall set forth on such Bond the date of such authentication.

15

Section 2.05.

Transfer and Exchange of Bonds. Registration of any Bond may, in accordance with the terms of this Indenture, be transferred at the Principal Office of the Registrar, upon the books of the Registrar required to be kept pursuant to the provisions of Section 2.06 hereof, by the Person in whose name it is registered, in person or by its attorney duly authorized in writing, upon surrender of such Bond for cancellation, accompanied by a written instrument of transfer in a form approved by the Registrar, duly executed. The Registrar shall require the payment by the Owner of the Bond requesting such transfer of any tax or other governmental charge required to be paid and there shall be no other charge to any Owners for any such transfer. Whenever any Bond shall be surrendered for registration of transfer, the Issuer shall execute and the Registrar shall authenticate and deliver a new Bond or Bonds of the same tenor and of Authorized Denominations. No registration of transfer of Bonds shall be required to be made for a period of 15 days next preceding the date on which the Trustee sends by Mail any notice of redemption, nor shall any registration of transfer of Bonds called for redemption be required, except the unredeemed portion of any Bond being redeemed in part.

In the event any Owner fails to provide a correct taxpayer identification number to the Trustee, the Trustee may make a charge against the Owner sufficient to pay any government charge required to be paid as a result of such failure. In compliance with Section 3406 of the Code, this amount may be deducted by the Trustee from amounts payable to the Owner under this Indenture or the Bonds.

Bonds may be exchanged at the Principal Office of the Registrar for a like aggregate principal amount of Bonds of the same tenor and of Authorized Denominations. The Registrar shall require the payment by the Owner of the Bond requesting such exchange of any tax or other governmental charge required to be paid with respect to such exchange, and there shall be no other charge to any Owners for any such exchange. No exchange of Bonds shall be required to be made for a period of 15 days next preceding the date on which the Trustee Mails notice of redemption, nor shall any exchange of Bonds called for redemption be required, except the unredeemed portion of any Bond being redeemed in part.

The Issuer, the Registrar, the Trustee and any agent of the Issuer, the Registrar or the Trustee may treat the person in whose name the Bond is registered as the owner thereof for the purpose of receiving payment as herein provided and for all other purposes, whether or not the Bond be overdue, and neither the Issuer, the Registrar, the Trustee, nor any such agent shall be affected by notice to the contrary.

Section 2.06.

Section 2.07.

Bonds Mutilated, Lost, Destroyed or Stolen. If any Bond shall become mutilated, the Issuer, upon the request and at the expense of the Owner of said Bond, shall execute, and the Registrar shall thereupon authenticate and deliver, a new Bond of like tenor and number in exchange and substitution for the Bond so mutilated, but only upon surrender to the Registrar of the Bond so mutilated. Every mutilated Bond so surrendered to the Registrar shall be canceled by it and delivered to the Company. If any Bond issued hereunder shall be lost, destroyed or stolen, evidence of such loss, destruction or theft may be submitted to the Issuer, the Company and the Registrar, and if such evidence shall be satisfactory to them and indemnity satisfactory to them shall be given, the Issuer, at the expense of the Owner, shall execute, and the Registrar shall thereupon authenticate and deliver, a new Bond of like tenor in lieu of and in substitution for the Bond so lost, destroyed or stolen (or if any such Bond shall have matured or shall be about to mature, instead of issuing a substitute Bond the Registrar may pay the same without surrender thereof). The Issuer may require payment of a reasonable fee for each new Bond issued under this Section and payment of the expenses which may be incurred by the Issuer and the Registrar. Any Bond issued under the provisions of this Section in lieu of any Bond alleged to be lost, destroyed or stolen shall constitute an original additional contractual obligation on the part of the Issuer whether or not the Bond so alleged to be lost, destroyed or stolen be at any time enforceable by anyone, and shall be equally and proportionately entitled to the benefits of this Indenture with all other Bonds secured by this Indenture.

To the extent permitted by law, the provisions of this Section are exclusive and shall preclude all other rights and remedies with respect to the replacement or payment of mutilated, lost, destroyed or stolen Bonds.

Section 2.08.

Bonds; Limited Obligations. The Bonds, together with premium, if any, and interest thereon, shall be limited and not general obligations of the Issuer not constituting or giving rise to a pecuniary liability of the Issuer nor any charge against its general credit or taxing powers nor an indebtedness of or a loan of credit thereof within the meaning of any provision or limitation of the State Constitution or laws, shall be payable solely from the Revenues and other moneys pledged therefor under this Indenture, and shall be a valid claim of the respective Owners thereof only against the Bond Fund, the Revenues and other moneys held by the Trustee as part of the Trust Estate, subordinate to the rights of the Senior Lender under the Senior Loan. The Issuer shall not be obligated to pay the purchase price of Bonds from any source.

17

THE BONDS AND THE OBLIGATION TO PAY INTEREST THEREON AND PREMIUM WITH RESPECT THERETO ARE SPECIAL, LIMITED OBLIGATIONS OF THE ISSUER PAYABLE SOLELY OUT OF THE REVENUES AND INCOME DERIVED FROM THE AGREEMENT AND AS OTHERWISE PROVIDED IN THIS INDENTURE, AND SHALL NOT BE DEEMED TO CONSTITUTE AN INDEBTEDNESS OR AN OBLIGATION OF THE ISSUER, THE STATE OF INDIANA, OR ANY POLITICAL SUBDIVISION THEREOF WITHIN THE PURVIEW OF ANY CONSTITUTIONAL LIMITATION OR STATUTORY PROVISION. THE BONDS DO NOT NOW OR SHALL NEVER CONSTITUTE A CHARGE AGAINST THE GENERAL CREDIT OF THE ISSUER. THE BONDS ARE NOT IN ANY RESPECT A GENERAL OBLIGATION OF THE ISSUER, NOR ARE THEY PAYABLE IN ANY MANNER FROM REVENUES RAISED BY TAXATION.

No recourse shall be had for the payment of the principal of, or premium, if any, or interest on any of the Bonds or for any claim based thereon or upon any obligation, covenant or agreement contained in this Indenture, the Bonds, the Agreement or any other related documents, against any past, present or future officer, elected official agent or employee of the Issuer, or any incorporator, officer, director or member of any successor corporation, as such, either directly or through the Issuer or any successor corporation, under any rule of law or equity, statute or constitution or by the enforcement of any assessment or penalty or otherwise, and all such liability of any such incorporator, officer, director or member as such is hereby expressly waived and released as a condition of and in consideration for the execution of this Indenture and the issuance of any of the Bonds.

Section 2.09.

Disposal of Bonds. Upon payment of the principal of, premium, if any, and interest represented thereby or transfer or exchange pursuant to Section 2.05 hereof or replacement pursuant to Section 2.07 hereof, any Bond shall be canceled and such Bond shall be disposed of by the Registrar in accordance with its customary procedures and the Registrar shall provide evidence satisfactory to the Company of such cancellation and disposition.

Section 2.10.

Book-Entry System. (a) Unless otherwise determined by the Issuer, the Bonds shall be issued in the form of a single certificated fully-registered Bond, registered in the name of Cede & Co., as nominee of DTC, or any successor nominee (the “Nominee”). The actual owners of the Bonds (the “Beneficial Owners”) will not receive physical delivery of Bond certificates except as provided herein.

The Issuer, the Company, the Registrar and the Trustee may treat and consider the person in whose name each Bond is registered in the registration books kept by the Registrar as the absolute owner of such Bond for the purpose of payment of principal, purchase price, premium and interest with respect to such Bond, for the purpose of giving notices of redemption and other matters with respect to such Bond, for the purpose of registering transfers with respect to such Bond, and for all other purposes whatsoever. The Trustee shall pay all principal of and premium if any, and interest on, the Bonds only to or upon the order of the respective Owners, as shown in the registration books kept by the Registrar, or their respective attorneys duly authorized in writing, and all such payments shall be valid and effective to fully satisfy and discharge the Issuer’s obligations with respect to payment of principal of, and premium, if any, and interest on, the Bonds to the extent of the sum or sums so paid. No person other than an Owner, as shown in the registration books kept by the Registrar, shall receive a certificated Bond evidencing the obligation of the Issuer to make payments of principal, premium, if any, and interest pursuant to this Indenture.

(c)

The Issuer has executed and delivered to DTC a letter of representations in customary form with respect to the Bonds in book-entry form (the “DTC Representation Letter”).

DTC may determine to discontinue providing its services with respect to the Bonds at any time by giving reasonable notice to the Issuer or the Trustee and discharging its responsibilities with respect thereto under applicable law. The Issuer, with the consent of the Company, may terminate the services of DTC with respect to the Bonds. Upon the discontinuance or termination of the services of DTC with respect to the Bonds, unless a substitute securities depository is appointed to undertake the functions of DTC hereunder, the Issuer, at the expense of the Company, is obligated to deliver Bond certificates to the Beneficial Owners of such Bonds, as described in this Indenture, and such Bonds shall no longer be restricted to being registered in the registration books kept by the Registrar in the name of the Nominee, but may be registered in whatever name or names Owners transferring or exchanging Bonds shall designate, in accordance with the provisions of this Indenture. The Trustee, the Registrar and the Issuer may conclusively rely on information provided by DTC and DTC Participants as to the identity of the Owners and the amount owed.

19

Owners shall have no lien or security interest in any rebate or refund paid by DTC to the Trustee which arises from the payment by the Trustee of principal of, or premium, if any, or interest on, the Bonds in immediately available funds to DTC.

Section 2.11.

CUSIP Numbers. The Issuer in issuing the Bonds may use “CUSIP” numbers (if then generally in use), and, if so, the Trustee shall use CUSIP numbers in notices of redemption as a convenience to Owners; provided that any such notice may state that no representation is made as to the correctness of such numbers either as printed on the Bonds or as contained in any notice of a redemption and that reliance may be placed only on the other identification numbers printed on the Bonds, and any such redemption shall not be affected by any defect in or omission of such numbers. The Issuer or the Company will promptly notify the Trustee and the Registrar of any change in any CUSIP number(s).

None of the Issuer, the Registrar nor the Trustee shall have any responsibility for any defect in the CUSIP number that appears on any Bond, check, advice of payment or redemption notice, and any such document may contain a statement to the effect that CUSIP numbers have been assigned by an independent service for convenience of reference and that none of the Issuer, the Registrar nor the Trustee shall be liable for any inaccuracy in such matters.

Each such notice shall also state that the interest on the Bonds designated for redemption shall cease to accrue from and after such redemption date and that on said date there will become due and payable on each of said Bonds the principal amount thereof to be redeemed, interest accrued thereon, if any, to the redemption date and the premium, if any, thereon (such premium to be specified) and shall require that such Bonds be then surrendered at the address or addresses of the Trustee specified in the redemption notice. Notwithstanding the foregoing, failure by the Trustee to give notice pursuant to this Section 3.05 to anyone or more of the Information Services or Securities Depositories or the insufficiency of any such notices shall not affect the sufficiency of the proceedings for redemption. Failure to give any required notice of redemption as to any particular Bond shall not affect the validity of the call for redemption of any Bonds in respect of which no such failure has occurred.

(b)

With respect to any notice of optional redemption of Bonds in accordance with Section 3.02(b) hereof, unless, upon the giving of such notice, such Bonds shall be deemed to have been paid within the meaning of Article VII hereof, such notice may state that such redemption is conditioned upon the receipt by the Trustee, on or prior to the date fixed for such redemption, of moneys sufficient to pay the principal of, and premium, if any, and interest on, such Bonds to be redeemed. In the event such moneys are not so received, the redemption shall not be made and the Trustee shall within a reasonable time thereafter give notice, in the manner in which the notice of redemption was given, that such redemption will not take place.

Section 3.06.

Partial Redemption of Bonds. Upon surrender of any Bond redeemed in part only, the Registrar shall exchange the Bond redeemed for a new Bond of like tenor and in an Authorized Denomination without charge to the Owner in the principal amount of the portion of the Bond not redeemed. In the event of any partial redemption of a Bond which is registered in the name of Cede & Co., DTC may elect to make a notation on the Bond certificate which reflects the date and amount of the reduction in the principal amount of said Bond in lieu of surrendering the Bond certificate to the Registrar for exchange. The Issuer, the Company and the Trustee shall be fully released and discharged from all liability to the extent of payment of the redemption price for such partial redemption.

24

Section 3.07.

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 Section 8.01(c) hereof) of which an authorized officer of the corporate trust department of the Trustee has actual knowledge, there shall be no redemption of less than all of the Bonds at the time Outstanding.

Section 3.08.

Payment of Redemption Price. For the redemption of any of the Bonds, the Trustee shall deposit in the Principal Account or the Redemption Account of the Bond Fund, as the case may be, solely out of the Revenues and any other moneys constituting the Trust Estate, an amount sufficient to pay the principal of, and premium, if any, and interest to become due on, the Bonds called for redemption on the date fixed for such redemption. Such deposit shall be reduced by the amount of moneys in the Principal Account or the Redemption Account of the Bond Fund, as the case may be, or any fund in Article VII hereof available for and used on such redemption date for payment of the principal of, and premium, if any, and accrued interest on, the Bonds to be redeemed.

Section 3.09.

Effect of Redemption. Notice of redemption having been duly given as aforesaid, and moneys for payment of the redemption price being held by the Trustee if such redemption was conditioned thereon, the Bonds so called for redemption shall, on the redemption date designated in such notice, become due and payable at the redemption price specified in such notice, interest on the Bonds so called for redemption shall cease to accrue, said Bonds shall cease to be entitled to any lien, benefit or security under this Indenture, and the Owners of said Bonds shall have no rights in respect thereof except to receive payment of the redemption price thereof, without interest accrued on any funds held to pay such redemption price accruing after the date of redemption.

All Bonds fully redeemed pursuant to the provisions of this Article III shall be canceled upon surrender thereof to the Trustee, which shall upon the written request of the Company, deliver to the Company a certificate evidencing such cancellation.

Anything contained in this Indenture to the contrary notwithstanding, it is hereby understood and agreed that all of the representations and warranties or covenants of the Issuer contained in this Indenture are subject to the limitations set forth in Section 2.08 hereof and are not intended to and do not create a general obligation of the Issuer.

No covenant or agreement contained in the Bonds, in this Indenture or in any other agreement referred in this Indenture shall be deemed to be the covenant or agreement of any trustee, officer, member, agent or employee of the Issuer in his or her individual capacity, and neither such persons nor any official executing the Bonds shall be liable personally on the Bonds or be subject to any personal liability or accountability by reason of the issuance thereof.

Section 4.03.

The Issuer shall upon the reasonable request of the Trustee, from time to time execute and deliver such further instruments and take such further action as may be reasonable (and consistent with the Bond Documents) and as may be required to effectuate the purposes of this Indenture or any provisions hereof, provided, however, that no such instruments or actions shall pledge the general credit or the full faith of the Issuer.

27

Section 4.05.

Arbitrage and Tax Covenants. Subject to the Company’s direction of the investment of moneys on deposit in certain funds pursuant to Section 6.01 hereof, the Issuer covenants that it will not take or fail to take any action and within the reasonable control of the Issuer that would impair the exclusion of interest on the Bonds from gross income for federal income tax purposes. Subject to the appropriate direction by the Company of the investment of moneys on deposit in certain funds pursuant to Section 6.01 hereof, the Issuer further will not knowingly act or fail to act so as to cause the proceeds of the Bonds, any moneys derived, directly or indirectly, from the use or investment thereof and any other moneys on deposit in any fund or account maintained in respect of the Bonds (whether such moneys were derived from the proceeds of the sale of the Bonds or from other sources) to be used in a manner which would cause the Bonds to be treated as “arbitrage bonds” within the meaning of Section 148 of the Code, or which would otherwise adversely affect the Tax-Exempt status of the Bonds. The Issuer shall be deemed to have complied with the requirements of this Section 4.06, so long as, the Issuer acts on the written direction of the Company, and the Issuer shall be required to take action only based upon the written direction of the Company.

Section 4.07.

Section 4.09.

Source of Payment of Bonds. The Bonds are not general obligations of the Issuer, nor are they payable in any manner from revenues raised by taxation, but are limited obligations payable solely from the Revenues. The Revenues have been pledged and assigned as security for the equal and ratable payment of the Bonds and shall be used for no other purpose than to pay the principal of, and premium, if any, and interest on, the Bonds, except as may be otherwise expressly authorized in this Indenture, the Agreement, the Subordinate Mortgage, the Subordinate Security Agreement or the Subordination Agreement.

FUND AND ACCOUNTS; DEPOSIT AND APPLICATION

OF BOND PROCEEDS; REVENUES

Section 5.01.

Creation of Bond Fund and Accounts; Debt Service Reserve Fund; Rebate Fund; Condemnation and Awards Fund. (a) There is hereby created by the Issuer and ordered established a separate Bond Fund, to be held by the Trustee and to be designated “City of Bluffton, Indiana Subordinate Solid Waste Disposal Facility Revenue Bonds, Series 2007A (Indiana Bio-Energy, LLC Ethanol Plant Project) Bond Fund” and therein created (i) a Principal Account, (ii) an Interest Account, (iii) a Redemption Account and (iv) a Capitalized Interest Account.

(b)

For purposes of satisfying (i) any deficiency in the Interest Account or the Principal Account, and (ii) a deficiency in the Redemption Account solely in connection with the mandatory redemption in whole of the Bonds upon a Determination of Taxability, there is hereby created by the Issuer and ordered established a separate Debt Service Reserve Fund, to be held by the Trustee and to be designated “City of Bluffton, Indiana Subordinate Solid Waste Disposal Facility Revenue Bonds, Series 2007A (Indiana Bio-Energy, LLC Ethanol Plant Project) Debt Service Reserve Fund.”

The Bonds shall be secured by the Debt Service Reserve Fund. The Debt Service Reserve Fund Requirement may be satisfied by the use of a Reserve Fund Credit Instrument.

(c)

For purposes of complying with the requirements of Section 148 of the Code, the Rebate Fund is hereby established with the Trustee to make arbitrage payments as contemplated by the Tax Agreement. The Trustee shall deposit such amounts into the Rebate Fund and pay such amounts from the Rebate Fund as it shall be directed by an Authorized Company Representative, in accordance with the Tax Agreement and Section 6.04 hereof. To the extent the amount in the Rebate Fund exceeds the Rebate Amount (as defined in the Tax Agreement), the Trustee shall withdraw such excess in accordance with Section 6.04(c) herein and apply such excess as provided therein. The Trustee shall have no responsibility for calculating the amount of arbitrage rebate with respect to the Bonds.

29

There is hereby established with the Trustee a “City of Bluffton, Indiana Subordinate Solid Waste Disposal Facility Revenue Bonds, Series 2007A (Indiana Bio-Energy, LLC Ethanol Plant Project) Condemnation and Awards Fund.”

Section 5.02.

Application of Bond Proceeds and Equity Contribution. (a) The Issuer will cause the proceeds of the initial sale of the Bonds to be deposited with the Trustee as described below. The Company will cause an equity contribution in the amount of $515,300 (the “Equity Contribution”) to be deposited with the Trustee on the Closing Date and applied as described below. The Trustee will hold those proceeds and the Equity Contribution in trust for the benefit of the Company and the Bondholders and will apply the proceeds and the Equity Contribution in accordance with this Section.

The Trustee shall deposit into the Interest Account of the Bond Fund all accrued interest, if any, received from the proceeds of the sale of the Bonds, to be held by the Trustee and applied solely to the payment of interest when due on the Bonds.

The Trustee shall deposit into the Capitalized Interest Account, capitalized interest in the amount of $2,476,352.66. On the Business Day preceding each Interest Payment Date during the Capitalized Interest Period, the Trustee shall transfer from the Capitalized Interest Account to the Interest Account an amount sufficient to pay the interest on the Bonds coming due on the next succeeding Interest Payment Date. Upon receipt of the Notice of Completion, the Trustee shall transfer any balance remaining in the Capitalized Interest Account to the Construction Fund, unless the Trustee has received a Favorable Opinion of Bond Counsel with respect to the continued use of moneys in the Capitalized Interest Account to pay interest on the Bonds.

If, on the Business Day preceding any Interest Payment Date, the amount on deposit in the Capitalized Interest Account is not sufficient to pay the interest coming due on the Bonds on such Interest Payment Date, the Trustee shall first transfer from the Debt Service Reserve Fund, and second, if needed for any Interest Payment Date occurring prior to the Completion Date, transfer from the Construction Fund to the Interest Account, without further authorization, an amount which, after giving effect to any transfer from the Capitalized Interest Account, is sufficient to pay interest on the Bonds due on such Interest Payment Date.

The Trustee shall deposit into the Debt Service Reserve Fund the amount of $2,200,000 to satisfy the initial Debt Service Reserve Requirement for the Bonds.

30

The Trustee will deposit $515,300 of the Company’s Equity Contribution into the “Costs of Issuance Fund” which is hereby created with the Trustee, to pay a portion of the costs of issuing the Bonds, including, without limitation, all printing and recording expenses in connection with this Indenture, the Agreement, the Subordinate Mortgage, the Subordinate Security Agreement, the Subordination Agreement, the Bonds, the preliminary official statement and official statement for the Bonds; legal fees; compensation to the underwriter (payable solely from the Company’s Equity Contribution); and the initial fees of the Issuer and the Trustee. The costs described above are payable upon submission of a written request from an Authorized Company Representative stating that the amount indicated thereon is justly due and owing, has not been the subject of another written request which has been paid and is a proper cost of issuing the Bonds. The Trustee may conclusively rely on such requisitions. Any moneys remaining in the Costs of Issuance Fund on the earlier of the payment of all costs of issuance of the Bonds or June 1, 2007 shall be transferred to the Construction Fund and applied as described below.

The Trustee will deposit all remaining proceeds from the initial sale of the Bonds and any excess proceeds from the Costs of Issuance Fund into the “Construction Fund,” which is hereby created with the Trustee. Moneys in the Construction Fund will be disbursed to pay the Project Costs (as defined below), or to reimburse the Company for Project Costs paid by it. Other than for disbursements from the Construction Fund to be used for the payment of capitalized interest on the Bonds during the Capitalized Interest Period as to which no further authorization for the Trustee is required, the Trustee shall disburse moneys in the Construction Fund upon receipt of a requisition, substantially in the form as attached hereto as Exhibit B, signed by an Authorized Company Representative and approved by an Authorized Senior Lender Representative stating with respect to each disbursement to be made, the following:

If the Trustee shall have received an Independent Engineer’s Certificate stating that the Net Proceeds are sufficient to repair, replace, rebuild or restore the Plant substantially to its prior condition, such Net Proceeds in the Condemnation and Awards Fund will be used at the written direction of the Company to repair, replace, rebuild or restore the Plant substantially to its prior condition. If the Net Proceeds exceed the cost of such repair, replacement, rebuilding or restoration, the Trustee shall transfer the balance of such moneys on deposit in the Condemnation and Awards Fund to the Redemption Account for the redemption of the Bonds, in whole or in part, in accordance with Section 3 .03( c) hereof, after making any transfer to the Rebate Fund pursuant to Section 4.2 of the Tax Agreement and Section 6.04 hereof, and after the completion of such repair, replacement, rebuilding or restoration.

36

(iii)

If an Event of Default shall exist at the time of the receipt by the Trustee of the Net Proceeds in the Condemnation and Awards Fund, unless the Event of Default would be cured upon the application of such Net Proceeds, the Trustee shall promptly request the written direction of the Owners of a majority in aggregate principal amount of the Bonds outstanding, and if such Event of Default shall not have been cured or waived, shall thereupon apply such Net Proceeds, after making any transfer to the Rebate Fund as directed pursuant to the Tax Agreement and Section 6.04 hereof, to the rebuilding, replacement, repair and restoration of the Plant, or for deposit in the Redemption Account as directed by such percentage of Bondholders (or if no such direction shall be received within 90 days after request therefor by the Trustee shall have been made, for deposit in the Redemption Account) provided, that no such directions shall allow for a distribution other than ratably among the Bondowners.

(iv)

The Trustee is hereby authorized to apply the amounts in the Condemnation and Awards Fund to the payment (or reimbursement to the extent the same have been paid by or on behalf of the Company or the Issuer) of the costs required for the rebuilding, replacement, repair and restoration of the Plant in accordance with the provisions of the Subordinate Mortgage and this Indenture and in substantially the same manner as provided for disbursements from the Construction Fund. The Trustee shall keep and maintain adequate records pertaining to the Condemnation and Awards Fund and all disbursements therefrom and shall furnish copies of same to the Issuer and the Company upon reasonable written request therefor.

(v)

The date of completion of the restoration of the Plant shall be evidenced to the Issuer and the Trustee by a Company’s Certificate stating (1) the date of such completion, (2) that all labor, services, machinery, equipment, materials and supplies used therefore and all costs and expenses in connection therewith have been paid for, (3) that the Plant has been restored to substantially its condition immediately prior to the loss event, or to a condition of at least equivalent value, operating efficiency and function, (4) that the Issuer has good and valid title to all property constituting part of the restored Plant, all property of the Plant is subject to the lien and security interest of the Subordinate Mortgage, (5) the Rebate Amount applicable with respect to the Net Proceeds and the earnings thereon (with a statement as to the determination of the Rebate Amount and a direction to the Trustee of any required transfer to the Rebate Fund), and (6) that the restored Plant is ready for occupancy, use and operation for its intended purposes. Notwithstanding the foregoing, such certificate shall state (x) that it is given without prejudice to any rights of the Company against third parties which exist at the date of such certificate or which may subsequently come into being, (y) that it is given only for the purposes of this Section, and (z) that no Person other than the Issuer or the Trustee may benefit therefrom. If the Net Proceeds received from the loss event shall be equal to or greater than $500,000, such certificate shall be accompanied by those same documents as are required to evidence the Completion Date of the Plant.

(vi)

All earnings on amounts on deposit in the Condemnation and Awards Fund shall be transferred by the Trustee and deposited in accordance with Section 5.03 hereof.

37

(vii)

Any surplus remaining in the Condemnation and Awards Fund after the completion of the rebuilding, replacement, repair and restoration of the Plant shall, after making any transfer to the Rebate Fund as directed pursuant to the Tax Agreement and Section 6.04 hereof, and after depositing in the Debt Service Reserve Fund an amount equal to any deficiency therein, be transferred by the Trustee to the Redemption Account.

(e)

Investment of Construction Fund Moneys. Moneys on deposit in the Construction Fund may be invested only in accordance with the provisions of Sections 6.03 and 6.05 of the Agreement and Article VI hereof, and income resulting therefrom shall be credited first to the Rebate Fund if required in the Tax Agreement and Section 6.04 hereof, and next to the Construction Fund.

(f) Redemption; Event of Default. If the Company is required to, or shall elect to redeem the Bonds in whole, any balance in the Construction Fund shall be deposited in the Redemption Account. If an Event of Default occurs and the maturity of the Bonds is accelerated, the Trustee will to the extent necessary transfer moneys in the Construction Fund to the Bond Fund, regardless of the other provisions of this Section.

Section 5.03.

38

(4)

Fourth, commencing on September 1, 2009, the Trustee shall deposit into the Principal Account of the Bond Fund amounts sufficient to pay one-sixth of the principal amount of the Bonds coming due on the next succeeding Principal Payment Date; and

(5)

Fifth, the Trustee shall deposit into the Debt Service Reserve Fund amounts necessary to cause the amount on deposit therein to equal the Debt Service Reserve Requirement and any deficiency in said Fund shall be replenished in accordance with Section 5.03(c)(ii) herein.

(ii)

Amounts transferred from the Capitalized Interest Account, the Construction Fund or the Debt Service Reserve Fund to pay interest on the Bonds shall be credited to the Interest Account.

(iii)

Excess or remaining amounts in the Construction Fund shall be credited as described in Section 5.02(c) hereof.

(1)

First, to the Rebate Fund as and if required by Section 4.2 of the Tax Agreement and Section 6.04 hereof;

(2)

Second, to the Construction Fund until the Completion Date; and

(3)

Last to the Interest Account.

(vi)

Investment income on the Capitalized Interest Account shall be credited to the Capitalized Interest Account.

(vii)

Investment income on the Debt Service Reserve Fund shall be credited as follows:

(1)

First, to the Debt Service Reserve Fund but only to the extent required to maintain the Debt Service Reserve Fund Requirement in accordance with Section 5.03(c)(ii) herein; and

(2)

Second, to the Interest Account.

39

(viii)

Amounts transferred from the Debt Service Reserve Fund pursuant to Section 5.03(c) hereof shall be deposited and credited to the Interest Account, the Principal Account or the Redemption Account, as the case may be.

(b)

(i) The Trustee shall on each Interest Payment Date pay or cause to be paid out of the Interest Account, the interest due on the Bonds, and further payout of the Interest Account any amounts required for the payment of accrued interest upon any purchase or redemption (including any mandatory Sinking Fund Installment redemption) of the Bonds.

(ii)

The Trustee shall on each Principal Payment Date payout of the Principal Account, the principal amount, if any, due on the Bonds, upon the presentation and surrender of the requisite Bonds. On each Sinking Fund Installment payment date, the Trustee shall pay in immediately available funds the amounts required for the Sinking Fund Installment due and payable with respect to Bonds which are to be redeemed from Sinking Fund Installments on such date (accrued interest on such Bonds being payable from the Interest Account). The Trustee shall call for redemption Bonds in a principal amount equal to the Sinking Fund Installment then due. Such call for redemption shall be made even though at the time of mailing of the notice of such redemption sufficient moneys therefor shall not have been deposited in the Bond Fund relating to such Bonds.

(iii)

Amounts in the Redemption Account shall be applied, at the written direction of the Company, as promptly as practicable, to the purchase of such Bonds at prices not exceeding the redemption price thereof applicable on the earliest date upon which such Bonds are next subject to redemption, plus accrued interest to the date of redemption. Any amount in the Redemption Account not so applied to the purchase of such Bonds by 45 days prior to the next date on which the Bonds are so redeemable shall be applied to the redemption of Bonds on such redemption date. Any amounts deposited in the Redemption Account and not applied within 12 months of their date of deposit to the purchase or redemption of Bonds shall be transferred to the Interest Account. Upon the purchase of any Bonds out of prepayments under the Agreement, or upon the redemption of any Bonds, an amount equal to the principal of such Bonds so purchased or redeemed shall be credited against the Sinking Fund Installments for such Bonds in such order as an Authorized Company Representative shall direct the Trustee in writing (or, in the absence of any such written direction, in inverse order of the due dates of such Sinking Fund Installments) until the full principal amount of such Bonds so purchased or redeemed shall have been so credited. The portion of any such Sinking Fund Installment remaining after the deduction of such amounts so credited shall continue to be deemed to be the amount of such Sinking Fund Installment for the purposes of any calculation thereof under this Indenture.

40

(iv)

In connection with purchases of Bonds out of the Bond Fund as provided in this Section, the Company shall arrange and the Trustee shall execute such purchases (through brokers or otherwise, and with or without receiving tenders) at the written direction of the Company; provided, however, that the Trustee may not effect such purchases through a broker unless the Company shall have previously approved in writing the use of such broker and the amount of such broker’s fees. The payment of the purchase price shall be made out of the moneys deposited in the Redemption Account and the payment of accrued interest shall be made out of moneys deposited in the Interest Account.

(v)

The Issuer shall receive a credit in respect of Sinking Fund Installments for any Bonds which are subject to mandatory Sinking Fund Installment redemption and which are delivered by the Issuer or the Company to the Trustee on or before the 45th day next preceding any Sinking Fund Installment payment date and for any Bonds which prior to said date have been purchased or redeemed (otherwise than through mandatory sinking fund redemption) and cancelled by the Trustee and not theretofore applied as a credit against any Sinking Fund Installment. Each Bond so delivered, cancelled or previously purchased or redeemed shall be credited by the Trustee at 100% of the principal amount thereof against the obligation of the Issuer to pay such Sinking Fund Installments in such order of the due dates of such Sinking Fund Installments and maturity as an Authorized Company Representative shall direct the Trustee in writing (or, in the absence of such written direction, in the inverse order of the due dates of such Sinking Fund Installments), and the principal amount of Bonds to be redeemed by application of Sinking Fund Installment payments shall be accordingly reduced.

(vi)

The Company shall on or before the 45th day next preceding each Sinking Fund Installment payment date furnish the Trustee with the Company’s certificate indicating whether or not and to what extent the provisions of this Section are to be availed of with respect to such Sinking Fund Installment payment, stating, in the case of the credit provided for, that such credit has not theretofore been applied against any Sinking Fund Installment and confirming that immediately available cash funds for the balance of the next succeeding prescribed Sinking Fund Installment payment will be paid on or prior to the next succeeding Sinking Fund Installment payment date.

(vii)

Moneys in the Redemption Account which are not set aside or deposited for the redemption or purchase of Bonds shall be transferred by the Trustee to the Interest Account or to the Principal Account.

(viii)

In the event that a deficiency shall exist in any account of the Bond Fund on any Interest Payment Date after giving effect to any transfers made pursuant to Sections 5.02, 5.03(a) and 5.03(c) hereof, the Trustee shall make demand on the Company for such deficiency.

41

(c)

(i) If on any Interest Payment Date or redemption date for the Bonds the amount in the Interest Account (after taking into account amounts available to be transferred to the Interest Account from the Capitalized Interest Account) shall be less than the amount of interest then due and payable on the Bonds, or if on any Principal Payment Date, the amount in the Principal Account shall be less than the amount of principal of the Bonds then due and payable, in each case, after giving effect to all payments received by the Trustee in immediately available funds by 10:00 a.m. (Indianapolis, Indiana time) on such date, the Trustee forthwith shall transfer moneys from the Debt Service Reserve Fund (including any amount derived from investment earnings), first to such Interest Account, and second to such Principal Account, all to the extent necessary to make good any such deficiency. If on any redemption date, solely in connection with the mandatory redemption in whole of the Bonds upon a Determination of Taxability, the amount in the Redemption Account shall be less than the amount of the aggregate principal amount of the Bonds to be redeemed plus accrued interest to said redemption date, after giving effect to all payments received by the Trustee in immediately available funds by 10:00 a.m. (Indianapolis, Indiana time) on such date, the Trustee forthwith shall transfer moneys from the Debt Service Reserve Fund (including any amount derived from investment earnings) to such Redemption Account all to the extent necessary to make good any such deficiency.

(ii)

On February 15 and August 15 of each year and upon any withdrawal from the Debt Service Reserve Fund, the Trustee shall determine the amount on deposit in the Debt Service Reserve Fund.

In the case of the Debt Service Reserve Fund, a “surplus” means the amount by which the amount on deposit therein is in excess of the Debt Service Reserve Fund Requirement with respect to the Bonds (including any amount derived from investment earnings). If a surplus exists as of any such valuation date, the Trustee shall transfer an amount equal to such surplus to the Interest Account.

In the case of the Debt Service Reserve Fund, a “deficiency” means the amount by which the amount on deposit therein is less than the Debt Service Reserve Fund Requirement with respect to the Bonds (including any amount derived from investment earnings). If on any such valuation date a deficiency exists, the Trustee shall notify the Issuer and the Company of such deficiency and that such deficiency shall be replenished by the Company over a twelve-month period following the date on which the Trustee has notified the Issuer and the Company of said deficiency. To the extent required to maintain the Debt Service Reserve Fund Requirement, investment earnings received on the investments in the Debt Service Reserve Fund shall be retained in such Fund.

42

Section 5.04.

Bonds Not Presented for Payment of Principal. In the event any Bonds shall not be presented for payment when the principal thereof becomes due, either at maturity or at the date fixed for redemption thereof or the acceleration of maturity, or in the event that any interest thereon is unclaimed, if moneys sufficient to pay such Bonds or interest are held by the Trustee, the Trustee shall segregate and hold such moneys in trust (but shall not invest such moneys), without liability for interest thereon, for the benefit of Owners of such Bonds who shall, except as provided in the following paragraph, thereafter be restricted exclusively to such fund or funds for the satisfaction of any claim of whatever nature on their part under this Indenture or relating to said Bonds or interest. Such Bonds which shall not have been so presented for payment shall be deemed paid for any purposes of this Indenture.

Any moneys which the Trustee shall segregate and hold in trust for the payment of the principal of or interest on any Bond and remaining unclaimed for two years after such principal or interest has become due and payable shall be paid by the Trustee to the Company upon written request of an Authorized Company Representative. After the payment of such unclaimed moneys to the Company, the Owner of such Bond shall look only to the Company for payment, and then only to the extent of the amount so repaid to the Company, and the Company shall not be liable for any interest thereon and shall not be regarded as a trustee of such money, and all liability of the Issuer and the Trustee with respect to such moneys shall thereupon cease.

Neither the Company nor the Issuer shall have any right, title or interest in or to any moneys held by the Trustee pursuant to this Section. The Trustee shall not be liable to the Issuer or any Owner for interest on funds held by it for the payment and discharge of the principal, interest, or premium on any of the Bonds to any Owner.

Section 5.05.

Payment to the Company. After the right, title and interest of the Trustee in and to the Trust Estate and all covenants, agreements and other obligations of the Issuer to the Owners shall have ceased, terminated and become void and shall have been satisfied and discharged in accordance with Section 5.04 and Article VII hereof, and all fees, expenses and other amounts payable to the Registrar, the Trustee and the Issuer pursuant to any provision of this Indenture shall have been paid, any moneys remaining in the Bond Fund, Debt Service Reserve Fund and the Rebate Fund shall be paid to the Company upon request of an Authorized Company Representative, other than any unclaimed moneys held pursuant to Section 5.04. The Trustee may conclusively rely on certificates of the Registrar as to the amount of any fees, expenses and other amounts owing to it.

43

ARTICLE VI

INVESTMENTS

Section 6.01.

Investment of Moneys in Funds. Subject to Section 4.06 hereof and the provisions of the Tax Agreement, moneys in the Construction Fund, the Bond Fund, the Condemnation and Awards Fund, the Debt Service Reserve Fund, the Costs of Issuance Fund and the Rebate Fund may be invested and reinvested in Investment Securities. Such investments shall be made by the Trustee, as specifically directed and designated by the Company in a certificate of an Authorized Company Representative. Each such certificate shall contain a statement that each investment so designated by the Company constitutes an Investment Security and can be made without violation of any provision hereof or of the Agreement, the Tax Agreement or applicable law. The Trustee shall be entitled to rely on each such certificate or advice and shall incur no liability for making any such investment so designated or for any loss, fee, tax or other charge incurred in selling such investment or for any action taken pursuant to this Section that causes the Bonds to be treated as “arbitrage bonds” within the meaning of Section 148 of the Code. No investment instructions shall be given by the Company if the investments to be made pursuant thereto would violate any covenant set forth in Section 4.06 hereof or the provisions of the Agreement or the Tax Agreement. The Trustee is hereby authorized, in making or disposing of any investment permitted by this Section 6.01, to deal with itself (in its individual capacity) or with anyone or more of its affiliates, whether it or such affiliate is acting as an agent of the Trustee or for any third person or dealing as principal for its own account. The Trustee shall not be responsible for any loss on any investment made in accordance herewith.

Section 6.02.

Conversion of Investment to Cash. As and when any amounts so invested may be needed for disbursements from the Construction Fund, the Bond Fund, the Debt Service Reserve Fund or the Rebate Fund, the Trustee shall cause a sufficient amount of such investments to be sold or otherwise converted into cash to the credit of such fund. As long as no Event of Default shall have occurred and be continuing, the Company shall have the right to designate the investments to be sold and to otherwise direct the Trustee in the sale or conversion to cash of such investments; provided that the Trustee shall be entitled to conclusively assume the absence of any Event of Default unless it has notice thereof within the meaning of Section 9.05 hereof.

Section 6.03.

Credit for Gains and Charge for Losses. Gains from investments shall be credited to and held in, and losses shall be charged to, the fund or account from which the investment is made.

44

Section 6.04.

Payments into Rebate Fund; Application of Rebate Fund. (a) The Rebate Fund and the amounts deposited therein shall not be subject to a security interest, pledge, assignment, lien or charge in favor of the Trustee or any Bondholder or any other Person.

(b)

The Trustee, on the first Business Day following each Computation Period (as defined in the Tax Agreement) and the receipt of a Company’s Certificate pursuant to Section 4.2 of the Tax Agreement, shall deposit in the Rebate Fund that amount, as shall be so specified in such certificate of written direction, from any of the following: (i) moneys furnished by the Company; (ii) any investment income on funds and accounts held by the Trustee in accordance with Article V hereof, and (iii) any excess or remaining amounts in the Construction Fund and the Condemnation and Awards Fund pursuant to Sections 5.02(c) and 5.02(d), respectively, hereof. If there has been delivered to the Trustee a certification of the Rebate Amount (as defined in the Tax Agreement) in conjunction with the completion of the Plant or the restoration of the Plant pursuant to Section 5.02(d) hereof, the Trustee shall at the written direction of an Authorized Company Representative deposit in the Rebate Fund such amount so specified in such certification as required in order that the amount held in the Rebate Fund after such deposit is equal to the Rebate Amount calculated at the completion of the Plant or the restoration of the Plant.

(c)

In the event that the amount on deposit in the Rebate Fund exceeds the Rebate Amount as determined in accordance with the Tax Agreement, the Trustee, upon the receipt of written instructions from an Authorized Company Representative, shall withdraw such excess amount and deposit it in the Construction Fund until the completion of the Plant, or, after the Completion Date, deposit it in the Interest Account.

(d)

The Trustee, upon the receipt of written instructions from an Authorized Company Representative, shall pay to the United States of America, out of amounts in the Rebate Fund, (i) not later than 30 days after the end of each five year period after the date of original issuance of the Bonds, an amount such that, together with prior amounts paid to the United States of America, the total paid to the United States of America is equal to 90% of the Rebate Amount with respect to the Bonds calculated as of the end of the most recent Computation Period, and (ii) not later than 30 days after the date on which all of the Bonds have been redeemed or paid in full, 100% of the Rebate Amount as of the end of the final Computation Period.

(e)

The Company has agreed in the Tax Agreement to retain an arbitrage rebate consultant to calculate the Rebate Amount at least each Computation Period, and annually at its discretion or as may be required for the preparation of its annual financial statements. In the event that the amounts available in the Rebate Fund are insufficient to pay the required rebate payment, the Company shall pay all amounts required to the Trustee for payment to the United States of America.

45

ARTICLE VII

DEFEASANCE

Section 7.01.

Defeasance. If the Issuer shall pay or cause to be paid to the Owner of any Bond secured hereby the principal of, and premium, if any, and interest due and payable, and thereafter to become due and payable, upon such Bond or any portion of such Bond in an Authorized Denomination thereof, such Bond or portion thereof shall cease to be entitled to any lien, benefit or security under this Indenture.

If the Issuer shall pay or cause to be paid the principal of, and premium if any, and interest due and payable on, all Outstanding Bonds, and thereafter to become due and payable thereon, and shall pay or cause to be paid all other sums payable hereunder by the Issuer, including any necessary and proper fees, compensation and expenses of the Trustee and the Registrar, then, and in that case, the right, title and interest of the Trustee in and to the Trust Estate shall thereupon cease, terminate and become void. In such event, the Trustee shall assign, transfer and turn over the Trust Estate to the Company and any surplus in the Bond Fund and any balance remaining in any other fund created under this Indenture shall be paid to the Company upon the request of an Authorized Company Representative, other than any unclaimed moneys held pursuant to Section 5.04. The Trustee may conclusively rely on certificates of the Registrar as to the amount of any fees, expenses and other amounts owing to it.

All or any portion of Bonds (in Authorized Denominations) shall, prior to the maturity or redemption date thereof, be deemed to have been paid within the meaning of this Article VII and for all purposes of this Indenture when:

(a)

in the event said Bonds or portions thereof have been selected for redemption in accordance with Section 3.04 hereof, the Trustee shall have given, or the Company shall have given to the Trustee in form satisfactory to it irrevocable instructions to give, on a date in accordance with the provisions of Section 3.05 hereof, notice of redemption of such Bonds or portions thereof;

(b)

there shall have been deposited with the Trustee moneys in an amount sufficient (without relying on any investment income), in the opinion of a firm of nationally recognized certified public accountants, to pay when due the principal of, and premium, if any, and interest due and to become due (which amount of interest to become due shall be calculated at the actual rate borne by such Bonds) on said Bonds or portions thereof on and prior to the redemption date or maturity date thereof, as the case may be;

46

(c)

in the event said Bonds or portions thereof do not mature and are not to be redeemed within the next succeeding 60 days, the Company on behalf of the Issuer shall have given the Trustee in form satisfactory to it irrevocable instructions to give, as soon as practicable in the same manner as a notice of redemption is given pursuant to Section 3.05 hereof, and a notice to the Owners of said Bonds or portions thereof that the deposit required by clause (b) above has been made with, and the opinion required by clause (b) above has been delivered to, the Trustee and that said Bonds or portions thereof are deemed to have been paid in accordance with this Article VII and stating the maturity date or redemption date upon which moneys are to be available for the payment of the principal of, and premium, if any, and interest on, said Bonds or portions thereof; and

(d)

the Trustee shall have received a Favorable Opinion of Bond Counsel with respect to such deposit.

Moneys deposited with the Trustee pursuant to this Article VII shall not be withdrawn or used for any purpose other than, and shall be held in trust for, the payment of the principal of, premium, if any, and interest on said Bonds or portions thereof; provided that such moneys, if not then needed for such purpose, shall to the extent practicable, be invested and reinvested in Government Obligations maturing on or prior to the Interest Payment Date next succeeding the date of investment or reinvestment, and interest earned from such investments shall be paid over to the Company, as received by the Trustee, free and clear of any trust, lien or pledge. If payment of less than all the Bonds is to be provided for in the manner and with the effect provided in this Article VII, the Trustee shall select such Bonds or portion of such Bonds in the manner specified by Section 3.04 hereof for selection for redemption of less than all Bonds in the principal amount permitted by Section 3.01(b) hereof.

Notwithstanding that all or any portion of the Bonds are deemed to be paid within the meaning of this Article VII, the provisions of this Indenture relating to (i) the registration and exchange of Bonds, (ii) replacement of mutilated, lost, destroyed or stolen Bonds, (iii) payment of the Bonds from the moneys deposited as described in this Article and (iv) payment, compensation, reimbursement and indemnification of the Trustee and the Registrar shall remain in full force and effect with respect to all Bonds until the maturity date thereof or the last date fixed for redemption of all Bonds prior to maturity and, in the case of clause (iv), until payment, compensation, reimbursement or indemnification, as the case may be, of the Trustee and the Registrar.

47

ARTICLE VIII

DEFAULTS AND REMEDIES

Section 8.01.

Events of Default. Each of the following events shall constitute and is referred to in this Indenture as an “Event of Default”:

(a)

a failure to pay the principal of or premium, if any, on any of the Bonds when the same shall become due and payable at maturity, upon redemption or otherwise;

(b)

a failure to pay an installment of interest on any of the Bonds for a period of 5 days after the date upon which such interest has become due and payable;

(c)

a failure by the Issuer to observe and perform any covenant, condition, agreement or provision (other than as specified in this Section 8.01 (a) and Section 8.01 (b) contained in the Bonds or in this Indenture on the part of the Issuer to be observed or performed, which failure shall continue for a period of 90 days after written notice, specifying such failure and requesting that it be remedied, shall have been given to the Issuer and the Company by the Trustee by registered or certified mail which may give such notice in its discretion and shall give such notice at the written request of the Owners of not less than a majority in principal amount of the Bonds then Outstanding, unless the Trustee, or the Trustee and the Owners of a principal amount of Bonds not less than the principal amount of Bonds the Owners of which requested such notice, as the case may be, shall agree in writing to an extension of such period prior to its expiration; provided, however, that the Trustee, or the Trustee and the Owners of such principal amount of Bonds, as the case may be, shall be deemed to have agreed to an extension of such period if corrective action is initiated by the Issuer or the Company on behalf of the Issuer within such period and is being diligently pursued; or

(d)

an “Event of Default” under the Agreement has occurred and is continuing.

If on the date on which payment of principal of, interest on or other amount in any respect of the Bonds is due, sufficient moneys are not available to make such payment after taking into account any funds available for said purpose in the Debt Service Reserve Fund, the Trustee shall promptly give telephonic notice of such insufficiency to the Company by notice to the President and Treasurer at the telephone number provided for in Section 12.08 hereof.

48

Section 8.02.

Acceleration; Other Remedies. (a) If an Event of Default described in Section 8.0l(a) or Section 8.01(b) or an Event of Default described in Section 8.0l(d) hereof resulting from an “Event of Default” under Section 8.01(a), Section 8.01(c) or Section 8.01(e) of the Agreement (of which the Trustee shall have received notice or be deemed to have notice pursuant to the provisions of Section 9.05 hereof) has occurred and has not been cured or waived, then the Trustee may, or upon the written request of the Owners of not less than a majority in principal amount of the Bonds then Outstanding, the Trustee shall, by written notice by registered or certified mail to the Issuer and the Company, declare the Bonds to be immediately due and payable, whereupon the Bonds shall without further action, become and be immediately due and payable, anything in this Indenture or in the Bonds to the contrary notwithstanding, and the Trustee shall give notice thereof by Mail to all Owners of Outstanding Bonds. Upon any declaration of acceleration, the Trustee shall immediately exercise such rights as it may have under the Agreement.

(b)

The provisions of Section 8.02(a) are subject further to the condition that if, after the principal of the Bonds shall have been so declared to be due and payable and before any judgment or decree for the payment of the moneys due shall have been obtained or entered as hereinafter provided, the Issuer shall cause the Company to deposit with the Trustee a sum sufficient to pay all matured installments of interest upon all Bonds, any unpaid purchase price and the principal of any and all Bonds which shall have become due otherwise than by reason of such declaration (with interest upon such principal and, to the extent permissible by law, on overdue installments of interest, at the rate per annum then borne by the Bonds) and such amount as shall be sufficient to cover reasonable compensation and reimbursement of expenses payable to the Trustee and all Events of Default (other than nonpayment of the principal of Bonds which shall have become due by said declaration) shall have been remedied, then, in every such case, such Event of Default shall be deemed waived and such declaration and its consequences rescinded and annulled; provided, however, that no such waiver, rescission and annulment shall extend to or affect any other Event of Default or subsequent Event of Default or impair any right, power or remedy consequent thereon. The Trustee shall send notice of any rescission to the Company.

(c)

Upon the occurrence and continuance of any Event of Default, then and in every such case the Trustee in its discretion, may, and upon the written request of the Owners of not less than a majority in principal amount of the Bonds then Outstanding and receipt of indemnity to its satisfaction (except against its own negligence or willful misconduct) shall in its own name and as the Trustee of an express trust:

(i)

by mandamus, or other suit, action or proceeding at law or in equity, enforce all rights of the Owners under, and require the Issuer or the Company to carry out any agreements with or for the benefit of the Owners of Bonds and to perform its or their duties under, the Act, the Agreement, this Indenture, the Subordinate Mortgage, the Subordinate Security Agreement and the Subordination Agreement, provided that any such remedy may be taken only to the extent permitted under the applicable provisions of the Agreement or this Indenture, as the case may be;

(ii)

bring suit upon the Bonds;

49

(iii)

by action or suit in equity require the Issuer to account as if it were the trustee of an express trust for the Owners of Bonds; or

(iv)

by action or suit in equity enjoin any acts or things which may be unlawful or in violation of the rights of the Owners of Bonds.

In exercising such rights and the rights given the Trustee under this Article VIII, the Trustee will take such action as, in the judgment of the Trustee applying the standards described in Section 9.17, would best serve the interests of the Bondholders, taking into account the provisions of the Subordinate Mortgage and the Subordinate Security Agreement.

(d)

Section 8.05.

Limitation on Owners’ Right to Institute Proceedings. No Owner shall have any right to institute any suit, action or proceeding in equity or at law for the execution of any trust or power hereunder, or any other remedy hereunder or in the Bonds, unless such Owner previously shall have given to the Trustee written notice of an Event of Default as herein above provided and unless the Owners of not less than a majority in principal amount of the Bonds then Outstanding shall have made written request of the Trustee so to do after the right to institute said suit, action or proceeding under Section 8.02 hereof shall have accrued, and shall have afforded the Trustee a reasonable opportunity to proceed to institute the same in either its or their name, and unless there also shall have been offered to the Trustee security and indemnity satisfactory to it against the costs, expenses and liabilities to be incurred therein or thereby (except against its own negligence or willful misconduct), and the Trustee shall not have complied with such request within a reasonable time; and such notification, request and offer of indemnity are hereby declared in every such case, at the option of the Trustee, to be conditions precedent to the institution of said suit, action or proceeding, it being understood and intended that no one or more of the Owners shall have any right in any manner whatever by his or their action to affect, disturb or prejudice the security of this Indenture, or to enforce any right hereunder or under the Bonds, except in the manner herein provided, and that all suits, actions and proceedings at law or in equity shall be instituted, had and maintained in the manner herein provided and for the equal benefit of all Owners.

Section 8.08.

No Remedy Exclusive. Except as provided in Section 2.07, no remedy herein conferred upon or reserved to the Trustee or to the Owners is intended to be exclusive of any other remedy or remedies, and each and every such remedy shall be cumulative, and shall be in addition to every other remedy given hereunder or under the Agreement, or now or hereafter existing at law or in equity or by statute; provided, however, that any conditions set forth herein to the taking of any remedy to enforce the provisions of this Indenture, the Bonds or the Agreement shall also be conditions to seeking any remedies at law or in equity or by statute pursuant to this Section 8.08.

Section 8.09.

52

(a)

Unless the principal of all the Bonds shall have been declared due and payable, all such moneys shall be applied (i) first, to the payment to the persons entitled thereto of all installments of interest then due on each Bond, with interest on overdue installments of interest, if lawful at the rate per annum then borne by such Bond, in the order of maturity of the installments of such interest and, if the amount available shall not be sufficient to pay in full any particular installment of interest, then to the payment ratably, according to the amounts due on such installment, and (ii) second, to the payment to the persons entitled thereto of the unpaid principal of any of the Bonds which shall have become due (other than Bonds called for redemption for the payment of which money is held pursuant to the provisions of this Indenture) with interest on each Bond at its rate from the respective dates upon which it became due and, if the amount available shall not be sufficient to pay in full Bonds due on any particular date, together with such interest, then to the payment ratably, according to the amount of principal and interest due on such date, in each case to the persons entitled thereto, without any discrimination or privilege.

(b)

If the principal of all the Bonds shall have been declared due and payable, all such moneys shall be applied to the payment of the principal and interest then due and unpaid upon the Bonds, with interest on overdue interest and principal as aforesaid, without preference or priority of principal over interest or interest over principal or of any installment of interest over any other installment of interest, or of any Bond over any other Bond, ratably, according to the amounts due respectively for principal and interest, to the persons entitled thereto without any discrimination or privilege.

(c)

Whenever the Trustee shall apply such funds, it shall fix the Bond Payment Date upon which such application is to commence and upon such Bond Payment Date interest on the amounts of principal and interest to be paid on such Bond Payment Date shall cease to accrue. The Trustee shall give notice of the deposit with it of any such moneys and of the fixing of any such Bond Payment Date by Mail to the Provider and all Owners of Outstanding Bonds and shall not be required to make payment to any Owner until such Bond shall be presented to the Registrar for appropriate endorsement or cancellation if fully paid.

TRUSTEE; REGISTRAR

Section 9.01.

Acceptance of Trusts. The Issuer has appointed U.S. Bank National Association, as Trustee (and paying agent for the Bonds). The Trustee hereby accepts and agrees to execute the trusts hereby created, but only upon the additional terms set forth in this Article IX, to all of which the Issuer agrees and the respective Owners agree by their acceptance of delivery of any of the Bonds. The Trustee, prior to the occurrence of an Event of Default and after the curing of all Events of Default, undertakes to perform such duties and only such duties as are specifically set forth herein, and no implied covenant shall be read into this Indenture against the Trustee.

Section 9.02.

No Responsibilities for Recitals. The recitals, statements and representations contained in this Indenture or in the Bonds shall not be taken and construed as made by or on the part of the Trustee, and the Trustee does not assume, and shall not have, any responsibility or obligation for the correctness of any thereof or for the validity, sufficiency or priority of this Indenture or the Agreement, or the perfection or the maintenance of the perfection of any security interest granted hereby.

Section 9.03.

Limitations on Liability. The Trustee may execute any of the trusts or powers hereof and perform the duties required of it hereunder by or through attorneys, agents, receivers or employees, and shall be entitled to and may conclusively rely upon advice of counsel concerning all matters of trust and its duties hereunder and shall not be answerable for the conduct of any such attorney, agent, receiver or employee if appointed by the Trustee with reasonable care, and the advice of any such counsel shall be full and complete authorization and protection in respect of any action taken, suffered or omitted hereunder in good faith and reliance thereon, and may in all cases pay such reasonable compensation to such attorneys, agents, receivers or employees as may be reasonably employed in connection with the trusts hereof. The Trustee shall not be answerable for the exercise of any discretion or power under this Indenture or for anything whatsoever in connection with the trusts created hereby, except only for its own negligence or willful misconduct.

54

The Trustee shall not be liable with respect to any action taken or omitted to be taken by it in good faith in accordance with the direction of the Owners of a majority in aggregate principal amount of the Bonds Outstanding relating to the time, method and place of conducting any proceeding or any remedy available to the Trustee, or exercising any trust or power conferred upon the Trustee under this Indenture.

No provision of this Indenture shall require the Trustee to expend or risk its own funds or otherwise incur any financial liability in the performance of any of its duties hereunder, or in the exercise of any of its rights or powers. The Trustee shall not be required to give any bond or surety in respect to the execution of its trusts and powers hereunder.

The permissive rights of the Trustee to do things enumerated in this Indenture shall not be construed as a duty unless so specified herein.

The Trustee shall not be liable for any error of judgment made in good faith by an officer, director or employee unless it shall be proved that the Trustee was negligent in ascertaining the pertinent facts.

The Trustee shall be under no obligation to exercise any of the rights or powers vested in it by this Indenture at the request, order or direction of any of the Owners pursuant to the provisions of this Indenture unless there shall have been provided to the Trustee reasonable security or indemnity against the costs, expenses and liabilities which may be incurred therein or thereby.

The Trustee shall not be responsible or liable for any loss suffered in connection with the investment of moneys made by it in accordance with Article VI.

In situations where a Favorable Opinion of Bond Counselor an opinion of Bond Counsel is required or requested to be delivered under this Indenture, the Agreement or the Tax Agreement after the date of delivery of the Bonds, the Trustee shall accept (unless otherwise directed by the Company) an opinion in such form and with such disclosures as may be required so that such opinion will not be treated as a “covered opinion” for purposes of the United States Treasury Department regulations governing practice before the Internal Revenue Service (Circular 230), 31 CFR Part 10.

Whether or not expressly so provided, every provision of this Indenture relating to the conduct or affecting the liability of the Trustee shall be subject to the provisions of this Article IX and shall extend to the Registrar and employees and agents of the Trustee and the Registrar.

55

Section 9.04.

Compensation, Expenses and Advances. The Trustee and the Registrar shall be entitled to such compensation as shall be agreed in writing with the Company for their services rendered hereunder (not limited by any provision of law in regard to the compensation of the trustee of an express trust) and to reimbursement for their out-of-pocket expenses (including reasonable counsel fees and expenses) reasonably incurred in connection therewith except as a result of their negligence or willful misconduct. If the Issuer shall fail to perform any of the covenants or agreements contained in this Indenture, the Trustee may, in its uncontrolled discretion and without notice to the Owners, at any time and from time to time, make advances to effect performance of the same on behalf of the Issuer, but the Trustee shall be under no obligation so to do; and any and all such advances shall bear interest at a rate per annum equal to the rate of interest then in effect and as announced by U.S. Bank National Association as its prime lending rate for domestic commercial loans in New York, New York; but no such advance shall operate to relieve the Issuer from any Event of Default. In no event shall the Trustee be liable for any claims resulting from any decision on its part not to advance funds as permitted in the immediately preceding sentence. In the Agreement, the Company has agreed that it will pay to the Trustee and the Registrar compensation and reimbursement of expenses and advances and certain indemnities, but the Company may, without creating an Event of Default, contest in good faith the reasonableness of any such expenses and advances. If the Company shall have failed to make any payment to the Trustee or the Registrar under the Agreement, then each of the Trustee and the Registrar shall have, in addition to any other rights hereunder, a claim, prior to the claim of the Owners, for the payment of their compensation and indemnities and the reimbursement of their expenses and any advances made by them, as provided in this Section 9.04, upon the moneys and obligations in the Bond Fund, except for moneys or obligations deposited with or paid to the Trustee for the redemption or payment of Bonds which are deemed to have been paid in accordance with Article VII hereof, or funds held pursuant to Section 5.04 hereof.

Notwithstanding any other provision of this Indenture, in each instance in which this Indenture shall provide for compensation, reimbursement or indemnification of the Trustee, such provision shall be deemed to provide for, whether or not expressly so stated, the payment of all related fees, costs, charges, advances and reasonable expenses of the Trustee (including, without limitation, reasonable attorneys’ fees and expenses), unless the context clearly indicates otherwise.

Without prejudice to any other rights available to the Trustee under applicable law, when the Trustee incurs expenses or renders services in connection with an Event of Default specified in Section 8.01(c) of the Agreement, the expenses (including the reasonable charges and expenses of its counsel) and the compensation for the services are intended to constitute expenses of administration under any applicable federal or state bankruptcy, insolvency or other similar law.

The provisions of this Section 9.04 shall survive the termination of this Indenture.

56

Section 9.05.

Notice of Events of Default and Determination of Taxability. Notwithstanding anything otherwise provided herein, the Trustee shall not be required to take notice, or be deemed to have notice of any default or Event of Default, other than an Event of Default under Section 9.01(a) or Section 9.01(b) hereof, unless the Trustee shall have actual knowledge thereof or shall have been specifically notified in writing at the Principal Office of the Trustee, Attention: Corporate Trust, of such Event of Default by the Owners of at least 25% in principal amount of the Bonds then Outstanding, the Issuer or the Company. The Trustee may, however, at any time, in its discretion, require of the Issuer full information and cooperation as to the performance of any of the covenants, conditions and agreements contained herein. Such inquiry shall not for the purposes of this Section 9.05 constitute notice of any Event of Default. The Issuer shall not be required to take notice, or be deemed to have notice, of any Event of Default, other than an Event of Default of which it shall have actual knowledge. If an Event of Default occurs after the Trustee has notice of the same as provided in this Section 9.05, or if a Determination of Taxability occurs of which the Trustee has received notice as provided in Section 9.02 of the Agreement, then the Trustee shall give notice thereof by Mail to the Company and the Owners of Outstanding Bonds.

Section 9.06.

Action by Trustee. Except as provided in Section 8.02 and Section 8.04 hereof and except for the payment of principal of, and premium, if any, and interest on, the Bonds when due from moneys held by the Trustee as part of the Trust Estate, the Trustee shall be under no obligation to take any action in respect of any Event of Default or toward the execution or enforcement of any of the trusts hereby created, or to institute, appear in or defend any suit or other proceeding in connection therewith, unless requested in writing so to do by the Owners of at least a majority in principal amount of the Bonds then Outstanding and, if in its opinion such action may tend to involve it in expense or liability, unless furnished, from time to time as often as it may require, with security and indemnity satisfactory to it (except against its own negligence or willful misconduct); but the foregoing provisions are intended only for the protection of the Trustee, and shall not affect any discretion or power given by any provisions of this Indenture to the Trustee to take action in respect of any Event of Default without such notice or request from the Owners, or without such security or indemnity.

57

Section 9.07.

Good-Faith Reliance. The Trustee and the Registrar shall be protected and shall incur no liability in acting or proceeding in good faith upon any resolution, notice, telegram, telex or facsimile transmission, request, consent, waiver, certificate, statement, affidavit, voucher, bond, requisition or other paper or document which it shall in good faith believe to be genuine and to have been passed or signed by the proper board, body or person or to have been prepared and furnished pursuant to any of the provisions of this Indenture or the Agreement, or upon the written opinion of any attorney, engineer, accountant or other expert believed, without independent investigation, by the Trustee or the Registrar, as the case may be, to be qualified in relation to the subject matter. The Trustee and the Registrar shall be under no duty to make any investigation or inquiry as to any statements contained or matters referred to in any such instrument, but may accept and rely upon the same as conclusive evidence of the truth and accuracy of such statements; provided, however, that the Trustee may, in its discretion, make, but shall in no case be required to make, such further inquiry or investigation into such facts or matters as it may see fit, and, if the Trustee shall determine to make such further inquiry or investigation it shall be entitled to examine the books, records and premises of the Company personally or by agent or attorney. Neither the Trustee nor the Registrar shall be bound to recognize any person as an Owner or to take any action at such person’s request unless satisfactory evidence of the ownership of such Bond shall be furnished to such entity.

Whenever in the administration of this Indenture the Trustee shall deem it desirable that a matter be proved or established prior to taking, suffering or omitting any action hereunder, the Trustee (unless other evidence be herein specifically prescribed) may, in the absence of negligence or bad faith on its part, request and conclusively rely upon a certificate of an Authorized Company Representative or an Executive Officer, and, prior to the occurrence of a default of which the Trustee has been notified as provided in Section 9.05 or of which by said section it is deemed to have notice, the Trustee shall also be at liberty to accept a similar certificate to the effect that any particular dealing, transaction or action is necessary or advisable, but shall in no case be bound to secure the same.

The Trustee may execute any of the trusts or powers hereunder or perform any duties hereunder either directly or by or through agents or attorneys and the Trustee shall not be responsible for any misconduct or negligence on the part of any agent or attorney appointed with due care by it hereunder.

Notwithstanding anything elsewhere in this Indenture contained, the Trustee or the Registrar, as the case may be, shall have the right, but shall not be required, to demand, in respect of the authentication of any Bonds or the taking of any other action whatsoever within the purview of this Indenture or the Agreement, any showings, certificates, opinions or other information, or corporate action or evidence thereof, in addition to those by the terms hereof or thereof required as a condition of such action which are reasonably deemed desirable by the Trustee or the Registrar, as the case may be, for the purpose of establishing the right of the Issuer or the Company to request the taking of such action by the Trustee or the Registrar.

58

Section 9.08.

Dealings in Bonds; Allowance of Interest. The Trustee and the Registrar, in its individual capacity, may in good faith buy, sell, own, hold and deal in any of the Bonds issued hereunder and may join in any action which any Owner may be entitled to take with like effect as if it did not act in any capacity hereunder. The Trustee or the Registrar, in its individual capacity, either as principal or agent, may also engage in or be interested in any financial or other transaction with the Issuer or the Company, and may act as depositary, trustee or agent for any committee or body of Owners secured hereby or other obligations of the Issuer or the Company as freely as if it did not act in any capacity hereunder.

All moneys received by the Trustee shall, until used or applied 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. The Trustee shall be under no liability for interest on any moneys received hereunder except for accounting for income from Investment Securities.

Section 9.09.

Several Capacities. Anything in this Indenture to the contrary notwithstanding, with the consent of the Company, the same entity may serve hereunder as the Trustee and the Registrar and in any other combination of such capacities, to the extent permitted by law.

Section 9.10.

Resignation of Trustee. The Trustee may resign and be discharged of the trusts created by this Indenture by executing any instrument in writing resigning such trust and specifying the date when such resignation shall take effect, and filing the same with the Issuer, the Company and the Registrar not less than 45 days before the date specified in such instrument when such resignation shall take effect, and by giving notice of such resignation by Mail not less than three weeks prior to such resignation date, to all Owners of Bonds. Such resignation shall take effect on the day specified in such instrument and notice, unless previously a successor Trustee shall have been appointed as hereinafter provided, in which event such resignation shall take effect immediately upon the appointment of such successor Trustee, but in no event shall a resignation take effect earlier than the date on which a successor Trustee, acceptable to the Issuer and the Company, has been appointed and has accepted its appointment.

Section 9.11.

Removal of Trustee. (a) The Trustee may be removed at any time by filing with the Trustee so removed and with the Issuer, the Company and the Registrar, an instrument or instruments in writing executed by (x) the Company, if no default or Event of Default or condition which with the giving of notice or the passage of time, or both, would constitute a default or an Event of Default, shall have occurred and be continuing, or (y) during the occurrence and continuation of a default or an Event of Default or condition which with the giving of notice or the passage of time, or both, would constitute a default or an Event of Default, the Owners of not less than a majority in principal amount of the Bonds then Outstanding.

59

(c)

In no event shall a removal take effect earlier than the date on which a successor Trustee has been appointed and has accepted its appointment.

Section 9.12.

Appointment of Successor Trustee. In case at any time the Trustee shall be removed, or be dissolved, or if its property or affairs shall be taken under the control of any state or federal court or administrative body because of insolvency or bankruptcy, or for any other reason, then a vacancy shall forthwith and ipso facto exist in the office of Trustee and a successor may be appointed, and in case at any time the Trustee shall resign, then a successor may be appointed by filing with the Issuer, the Company and the Registrar an instrument in writing executed by the Company if no default or Event of Default or condition which with the giving of notice or the passage of time, or both, would constitute a default or an Event of Default, is then existing under Section 8.01 of the Agreement or Section 8.01(a) or (b) of this Indenture or, if a default is then existing, by the Owners of not less than a majority in principal amount of the Bonds then Outstanding. Copies of such instrument shall be promptly delivered by the Issuer to the predecessor Trustee and to the Trustee so appointed. Any successor Trustee appointed upon the removal of the original Trustee hereunder shall assume the obligations of the original Trustee through an instrument of acceptance.

Until a successor Trustee shall be appointed by the Company or the Owners as herein authorized, the Issuer, by an instrument authorized by the governing body of the Issuer, shall appoint a successor Trustee acceptable to the Company. After any appointment by the Issuer, it shall cause notice of such appointment to be given to the Registrar and to be given by Mail to all Owners of Bonds.

61

A-3

The Bonds shall be redeemed in whole or in part, and if in part by such method as the Trustee may deem fair and appropriate, at any time at a redemption price equal to 100% of the principal amount thereof, plus accrued interest to the redemption date upon receipt by the Trustee of a written notice from the Company stating that any of the following events has occurred and that the Company therefore intends to exercise its option to prepay the payments due under the Agreement in whole or in part and thereby effect the redemption of Bonds in whole or in part out of moneys available pursuant to the Indenture and, if necessary, Company funds: (a) the Company shall have determined or concurred in a determination that the continued operation of the Plant is impracticable, uneconomical or undesirable for any reason; (b) all or substantially all of the Plant shall have been condemned or taken by eminent domain; (c) the operation of the Plant shall have been enjoined or shall have otherwise been prohibited by, or shall conflict with, any order, decree, rule or regulation of any court or of any federal, state or local regulatory body, administrative agency or other governmental body; or (d) unreasonable burdens or excessive liabilities shall have been imposed upon the Company in respect of all or a part of the Project or the Plant including, without limitation, federal, state or other ad valorem, property, income or other taxes not being imposed on the date of the Agreement, as well as any statute or regulation enacted or promulgated after the date of the Agreement that prevents the Company from deducting interest in respect of the Agreement for federal income tax purposes.

The Bonds shall be subject to optional redemption upon prepayment of the Loan Payments at the option of the Company, in whole, or in part by lot, prior to their maturity, on any date during the redemption periods specified below, in each case in whole or in part, at the redemption prices (expressed as percentages of principal amount) hereinafter indicated plus accrued interest, if any, to the redemption date:

The Bonds shall be redeemed in whole on any date from amounts which are to be prepaid by the Company under the Agreement, at a redemption price equal to 100% of the principal amount thereof plus interest accrued, if any, to the redemption date within 180 days after the occurrence of a Determination of Taxability; provided that if, in the opinion of Bond Counsel delivered to the Trustee, the redemption of a specified portion of the Bonds outstanding would have the result that interest payable on the Bonds remaining outstanding after such redemption would remain Tax-Exempt, then the Bonds shall be redeemed in part by such method as the Trustee may deem fair and appropriate (in Authorized Denominations), in such amount as Bond Counsel in such opinion shall have determined is necessary to accomplish that result.

A-5

A “Determination of Taxability” shall be deemed to have occurred if as a result of the Company’s failure to observe any covenant, agreement or representation in the Agreement, a final decree or judgment of any federal court or a final action of the Internal Revenue Service determines that interest paid or payable on any Bond is or was includible in the gross income of an Owner of the Bonds for federal income tax purposes under the Code (other than an Owner who is a “substantial user” or “related person” within the meaning of Section 147(a) of the Code). However, no such decree or action will be considered final for this purpose unless the Company has been given written notice of the same, either directly or in the name of any Owner of a Bond, and, if it is so desired and is legally allowed, has been afforded the opportunity to contest the same, either directly or in the name of any Owner of a Bond, and until conclusion of any appellate review, if sought.

Following an occurrence in which the Plant is taken by eminent domain or threat thereof, or is damaged or destroyed, the Bonds shall be subject to mandatory redemption, in whole or in part by lot (or such other random means selected by the Trustee), on the earliest practicable date thereafter (which date shall be not less than 45 days from the date the Trustee transfers any moneys in the Condemnation and Awards Fund to the Redemption Account in accordance with the terms of the Indenture), at a redemption price equal to the principal amount thereof, together with accrued interest to the date of redemption.

Notice of any optional or mandatory redemption shall be given by first-class mail not less than 30 days (except as provided in the Indenture) nor more than 60 days prior to the date fixed for redemption to the Owners of Bonds at the address shown on the registration books of the Registrar on the date such notice is mailed. Except as described above for partial redemptions upon a Determination of Taxability, if less than all of the Bonds are called for redemption, the Trustee shall select the Bonds or any given portion thereof from the outstanding Bonds or such given portion thereof not previously called for redemption, by such method as the Trustee may deem fair and appropriate. For the purpose of any such selection the Trustee shall assign a separate number for each minimum Authorized Denomination of each Bond of a denomination of more than such minimum; provided that, following any such selection, both the portion of such Bond to be redeemed and the portion remaining shall be in Authorized Denominations.

Any notice of optional redemption of Bonds may state that such redemption is conditioned upon the receipt by the Trustee, on or prior to the date fixed for such redemption, of moneys sufficient to pay the principal of, and premium, if any, and interest on, such Bonds to be redeemed. In the event such moneys are not so received, the redemption shall not be made and the Trustee shall within a reasonable time thereafter give notice, in the manner in which the notice of redemption was given, that such redemption will not take place.

Subject to the limitations and upon payment of the charges, if any, provided in the Indenture, Bonds may be exchanged at the Principal Office of the Registrar for a like aggregate principal amount of Bonds of the same tenor and of Authorized Denominations.

A-6

This Bond is transferable by the person in whose name it is registered, in person, or by its attorney duly authorized in writing, at the Principal Office of the Registrar, but only in the manner, subject to the limitations and upon payment of the charges, if any, provided in the Indenture, and upon surrender and cancellation of this Bond accompanied by a written instrument of transfer in a form approved by the Registrar, duly executed. Upon such transfer a new fully registered Bond or Bonds in Authorized Denominations, for the same aggregate principal amount, will be issued to the transferee in exchange therefor.

The Issuer, the Registrar, the Trustee and any agent of the Issuer, the Registrar or the Trustee may treat the person in whose name this Bond is registered as the owner hereof for the purpose of receiving payment as herein provided and for all other purposes, whether or not this Bond be overdue, and neither the Issuer, the Registrar, the Trustee nor any such agent shall be affected by notice to the contrary.

The Bonds are equally and ratably secured, to the extent provided in the Indenture, by the pledge thereunder of the Trust Estate, subordinate to the rights of the Senior Lender under the Senior Loan. The Issuer has also pledged and assigned to the Trustee as security for the Bonds all other rights and interests of the Issuer under the Agreement (other than its rights to indemnification, exemption from personal liability and certain administration expenses and certain other rights).

The Owner of this Bond shall have no right to enforce the provisions of the Indenture, or to institute action to enforce the covenants therein, or to take any action with respect to any Event of Default under the Indenture, or to institute, appear in or defend any suit or other proceeding with respect thereto, except as provided in the Indenture.

With certain exceptions as provided therein, the Indenture and the Agreement may be modified or amended by the Owners of not less than a majority in aggregate principal amount of all Bonds then Outstanding under the Indenture.

Reference is hereby made to the Indenture, the Agreement, the Subordinate Security Agreement, the Subordinate Mortgage, the Subordination Agreement and the Tax Agreement, copies of which are on file with the Trustee, for the provisions, among others, with respect to the nature and extent of the rights, duties and obligations of the Issuer, the Company, the Trustee, the Registrar and the Owners of the Bonds. The Owner of this Bond, by the acceptance hereof, is deemed to have agreed and consented to and to be bound by the terms and provisions of the Indenture, the Agreement, the Subordinate Security Agreement, the Subordinate Mortgage, the Subordination Agreement and the Tax Agreement.

A-7

The Indenture prescribes the manner in which it may be discharged, including (a) a provision that the Bonds shall be deemed to be paid if moneys sufficient to pay the principal of, premium, if any, and interest on the Bonds and all necessary and proper fees, compensation and expenses of the Trustee and the Registrar, shall have been deposited with the Trustee, after which the Bonds shall no longer be secured by or entitled to the benefits of the Indenture, except for the purposes of registration and exchange of Bonds and of delivery of the Bonds to the Trustee for purchase, and (b) a provision that, if the Bonds mature or are called for redemption pursuant to the Indenture, the Bonds shall be deemed to be paid if Government Obligations, as defined in the Indenture, maturing as to principal and interest in such amounts and at such times as to insure the availability of sufficient moneys to pay the principal of, premium, if any, and interest on the Bonds on and prior to the redemption date or maturity date thereof, and all necessary and proper fees, compensation and expenses of the Issuer, the Trustee and the Registrar, shall have been deposited with the Trustee, after which the Bonds shall no longer be secured by or entitled to the benefits of the Indenture, except for the purposes of registration and exchange of Bonds and of such payment.

No recourse shall be had for the payment of the principal of, premium, if any, or interest on any of the Bonds or for any claim based thereon or upon any obligation, covenant or agreement in the Indenture, the Bonds, the Agreement or any other related document contained, against any past, present or future officer, elected official agent or employee of the Issuer, or any incorporator, officer, director or member of any successor corporation, as such, either directly or through the Issuer or any successor corporation, under any rule of law or equity, statute or constitution or by the enforcement of any assessment or penalty or otherwise, and all such liability of any such incorporator, officer, director or member is hereby expressly waived and released as a condition of and in consideration for the execution of the Indenture and the issuance of any of the Bonds.

IT I S HEREBY CERTIFIED, RECITED AND DECLARED that all acts, conditions and things required to exist, happen and be performed precedent to and in the execution and delivery of the Indenture and the issuance of this Bond do exist, have happened and have been performed in due time, form and manner as required by law, and that the issuance of this Bond and the issue of which it forms a part, together with all other obligations of the Issuer, does not exceed or violate any constitutional or statutory limitation of indebtedness.

This Bond shall not be entitled to any security or benefit under the Indenture, or be valid or become obligatory for any purpose, until this Bond shall have been authenticated by the execution by the Registrar of the certificate of authentication inscribed hereon.
