The Adair County Industrial Authority (the “Authority”), a public trust organized and existing under the laws of the State of Oklahoma for the benefit of Adair County, Oklahoma (the “County”), for value received, hereby promises to pay, from the sources hereinafter described, the Principal Amount stated above, in lawful money of the United States of America, to the Registered Owner stated above or the registered assigns, on the Maturity Date stated above (unless this Bond shall have been called for prior redemption, in which case on such redemption date), upon the presentation and surrender hereof at the designated corporate trust office of Bank of Oklahoma, N.A., as Trustee (the “Trustee”), in Oklahoma, City, Oklahoma, or at the principal office of its successor in trust under an Indenture of Trust, dated as of December 1, 2007 (the “Indenture”), between the Authority and the Trustee, and to pay, from like sources, to the Registered Owner stated above as of the close of business on the first day of the calendar month immediately prior to an Interest Payment Date (the “Regular Record Date”), by check or draft mailed by the Trustee on the Interest Payment Date to such Registered Owner at his address as it last appears on the registration books kept for that purpose at the office of the Trustee, interest on said sum in like coin or currency from the Original Issue Date stated above or from the most recent date from which interest has been paid or duly provided for, at the Interest Rate stated above, payable semiannually on June 15 and December 15 of each year, commencing June 15, 2008, on the basis of a 360-day year composed of twelve 30-day months, until payment of the principal hereof has been made or provided for. The Trustee may make payments of principal at maturity or upon redemption and payment of interest by wire transfer within the United States to any owner of at least $1,000,000 in aggregate principal amount of the Bonds requesting the same in writing addressed to the Trustee as provided in this Indenture. Any interest not timely paid or duly provided for shall cease to be payable to the Registered Owner hereof at the close of business on the applicable Regular Record Date and shall be payable to the Registered Owner hereof at the close of business on a Special Record Date (as defined in the Indenture) for the payment of any defaulted interest. Such Special Record Date shall be fixed by the Trustee whenever monies become available for payment of the defaulted interest, and notice of such Special Record Date shall be given to the Registered Owner hereof not less than ten calendar days prior thereto. If the date for making any payment or the last day for performance of any act or the exercise of any right, as provided in this Bond, shall not be a “Business Day” as defined in this Indenture, such payment may be made or act performed or right exercised on the next succeeding Business Day with the same force and effect as if done on the nominal date provided in this Bond. Notwithstanding anything herein to the contrary, when this Bond is registered in the name of a Depository (as defined in this Indenture) or its nominee, the principal and redemption price of and interest on this Bond shall be payable in same day or federal funds delivered or transmitted to the Depository or its nominee.

This Bond is one of a duly authorized series of bonds of the Authority designated as “Adair County Industrial Authority Solid Waste Recovery Facilities Revenue Bonds (Advanced Environmental Recycling Technologies, Inc. Project) Series 2007” (the “Bonds”). The Bonds have been issued under Title 60 Oklahoma Statutes 2001, Section 176 et seq., as amended (the “Act”), to finance and refinance costs of acquiring, constructing and equipping certain solid waste recovery facilities (the “Facilities”); to fund six months of capitalized interest on the Series

2007 Bonds; to fund a reserve fund with respect to the Series 2007 Bonds; and to fund certain costs of issuing the Series 2007 Bonds.

This Bond is a limited obligation of the Authority payable solely from and secured by (a) a pledge of certain rights of the Authority under and pursuant to the Loan Agreement dated as of December 1, 2007 (the “Loan Agreement”), between the Authority and Advanced Environmental Recycling Technologies, Inc. (the “Company”); (b) a pledge of the Funds and Pledged Revenues other than the Rebate Fund (all as defined in the Indenture); (c) a mortgage interest on the Springdale Property, the Watts Property, the Lowell Property and the Junction Property (each as defined in the Indenture) (including personal property and equipment); (d) a Patent and Trademark Security Agreement from the Company for the benefit of the Trustee; and (e) an assignment of the Weyerhaeuser Agreement (as defined in the Indenture).

This Bond shall not constitute or become an indebtedness, a debt or a liability of or a charge against the general credit or taxing power of the State of Oklahoma or any political subdivision thereof, including the County, but shall constitute a special, limited revenue obligation of the Authority only payable solely from and only to the extent of the revenues pledged in the Indenture, and neither the State of Oklahoma, nor any political subdivision thereof, including the County, shall be liable hereon; nor shall this Bond constitute the giving, pledging, or loaning of the faith and credit of the State of Oklahoma, or any political subdivision thereof, including the County. The issuance of this Bond shall not, directly or indirectly or contingently, obligate the State of Oklahoma or any political subdivision thereof, including the County, to levy or collect any form of taxes or assessments therefor or to create any indebtedness payable out of taxes or assessments or make any appropriation for the payment of this Bond, and such appropriation or levy is prohibited. The Authority has no taxing power.

Reference is hereby made to the Indenture and the Loan Agreement for a description of the revenues pledged, the nature and extent of the security, the rights, duties and obligations of the Authority, the Trustee and the Registered Owners of the Bonds and the terms and conditions upon which the Bonds are, and are to be, secured, and a statement of the rights, duties, immunities and obligations of the Authority and the Trustee.

The Bonds are subject to optional redemption by the Authority upon the written direction of the Company Representative as a whole or in part at any time, at a redemption price equal to the principal amount thereof to be redeemed and accrued but unpaid interest to the redemption date, in certain events of damage, destruction or condemnation to the property of the Company located in Watts, Oklahoma. The Bonds are also subject to optional redemption by the Authority upon the written direction of the Company Representative, as a whole, but not in part, at redemption prices equal to 110% of the outstanding principal amount thereof to be redeemed and accrued but unpaid interest to the redemption date, as a condition precedent to the acquisition of substantially all of the assets of the Company or in the event of the merger or consolidation of the Company, as provided in the Loan Agreement.

The Bonds are also subject to mandatory sinking fund redemption by lot in such manner as the Trustee may determine pursuant to the Indenture, at a redemption price equal to 100% of the principal amount thereof and accrued but unpaid interest to the redemption date.

Upon the occurrence of a Determination of Taxability, as defined in this Indenture, the Bonds are subject to mandatory redemption in whole at a redemption price equal to 105% of the Outstanding principal amount thereof, plus unpaid interest accrued to the redemption date, at the earliest practicable date selected by the Trustee, after consultation with the Company, but in no event later than 45 calendar days following the Trustee’s notification of the Determination of Taxability. The occurrence of a Determination of Taxability with respect to the Bonds will not constitute an Event of Default under this Indenture and the sole remedy of the holders of the Bonds is the mandatory redemption of the Bonds pursuant to this paragraph.

In the event less than all Bonds are to be redeemed pursuant to the optional or special redemption provisions of this Indenture, they shall be redeemed in such order of maturity as the Company Representative shall determine (less than all of the Bonds of a single maturity to be selected by lot in such manner as the Trustee may determine). Except as hereinafter provided, notice of the call for redemption shall be given by the Trustee by mailing by first class mail a copy of the redemption notice not more than 45 days nor less than 30 days prior to the redemption date to the Registered Owners of Bonds to be redeemed in whole or in part at the address of such Registered Owner last showing on the registration books. Failure to give such notice or any defect therein shall not affect the validity of any proceedings for the redemption of such Bonds for which no such failure or defect occurs. All Bonds called for redemption will cease to bear interest after the specified redemption date, provided collected funds for their payment are on deposit at the place of payment at the time of redemption.

Notwithstanding the foregoing, no additional notice shall be required with respect to mandatory sinking fund redemption unless requested by the holders of 100% of the principal amount of the Bonds, and Bonds need not be presented for mandatory sinking fund redemption payment.

The Bonds are issuable only as fully registered bonds in the minimum denominations of $100,000 and in any integral multiple of $5,000 in excess thereof. The Bonds shall initially be registered in the name of Cede & Co., as nominee for The Depository Trust Company (“DTC”), to be held in a book-entry system and: (a) such Bonds shall be registered in the name of the DTC or its nominee, as Bondholder, and immobilized in the custody of DTC; (b) unless otherwise requested by DTC, there shall be a single Bond certificate for each maturity; and (c) such Bonds shall not be transferable or exchangeable, except for transfer to another Depository or another nominee of a Depository, without further action by the Authority. The owners of beneficial interest in the Bonds shall not have any right to receive Bonds in the form of physical certificates. If any Depository determines not to continue to act as a Depository for the Bonds for use in a book-entry system, the Authority may attempt to have established a securities depository/book-entry system relationship with another qualified Depository under this Indenture. If the Authority does not or is unable to do so, the Authority and the Trustee, after the Trustee has made provision for notification to the owners of beneficial interests by the then Depository, shall permit withdrawal of the Bonds from the Depository, and authenticate and deliver Bond certificates in fully registered form (in authorized denominations of not less than $100,000) to the assignees of the Depository or its nominee.

While a depository is the sole holder of the Bonds, delivery or notation of partial redemption of Bonds shall be effected in accordance with the provisions of the Letter of Representations, as defined in this Indenture.

In addition to the words and terms defined elsewhere in this Bond, the following terms shall have the following meanings:

“Beneficial Owner” means, with respect to the Bonds, a person owning a Beneficial Ownership Interest therein, as evidenced to the satisfaction of the Trustee.

“Beneficial Ownership Interest” means the beneficial right to receive payments and notices with respect to the Bonds which are held by a Depository under a book-entry system.

“Book-entry form” or “book-entry system” means, with respect to the Bonds, a form or system, as applicable, under which (a) the Beneficial Ownership Interests may be transferred only through a book-entry; and (b) physical Bond certificates in fully registered form are registered only in the name of a Depository or its nominee as holder, with the physical Bond certificates “immobilized” in the custody of the Depository. The book-entry system maintained by and the responsibility of the Depository (and not maintained by or the responsibility of the Authority or the Trustee) is the record that identifies, and records the transfer of the interests of, the owners of beneficial (book-entry) interests in the Bonds.

“Depository” means any securities depository that is a clearing agency under federal law operating and maintaining, with its participants or otherwise, a book-entry system to record ownership of book-entry interests in Bonds, and to effect transfers of book-entry interests in Bonds, and includes and means initially The Depository Trust Company (a limited purpose trust company), New York, New York.

“Direct Participant” means a Participant as defined in the Letter of Representations.

“Indirect Participant” means a person utilizing the book-entry system of the Depository by, directly or indirectly, clearing through or maintaining a custodial relationship with a Direct Participant.

NEITHER THE COUNTY, THE COMPANY, NOR THE TRUSTEE WILL HAVE ANY RESPONSIBILITY OR OBLIGATION TO ANY DIRECT PARTICIPANT, INDIRECT PARTICIPANT OR ANY BENEFICIAL OWNER OR ANY OTHER PERSON NOT SHOWN ON THE REGISTRATION BOOKS OF THE TRUSTEE AS BEING A HOLDER WITH RESPECT TO: (A) THE BONDS; (B) THE ACCURACY OF ANY RECORDS MAINTAINED BY DTC OR ANY DIRECT PARTICIPANT OR INDIRECT PARTICIPANT; (C) THE TIMELY OR ULTIMATE PAYMENT BY DTC OR ANY DIRECT PARTICIPANT OR INDIRECT PARTICIPANT OF ANY AMOUNT DUE TO ANY BENEFICIAL OWNER IN RESPECT OF THE PRINCIPAL OR REDEMPTION PRICE OF OR INTEREST ON THE BONDS; (D) THE DELIVERY BY ANY DIRECT PARTICIPANT OR INDIRECT PARTICIPANT OF ANY NOTICE TO ANY BENEFICIAL OWNER WHICH IS REQUIRED OR PERMITTED UNDER THE TERMS OF THIS INDENTURE TO BE GIVEN TO REGISTERED OWNERS; (E) THE SELECTION OF THE BENEFICIAL OWNERS TO RECEIVE PAYMENT IN THE EVENT OF ANY PARTIAL REDEMPTION OF THE

BONDS; OR (F) ANY CONSENT GIVEN OR OTHER ACTION TAKEN BY DTC AS REGISTERED OWNER.

Except for the 15 days next preceding the mailing of notice of redemption of the Bonds (and, if this Bond or portion thereof is called, the period following the giving of such notice), this Bond is fully transferable by the Registered Owner hereof in person or by his duly authorized attorney on the registration books kept at the designated office of the Trustee upon surrender of this Bond, together with a duly executed written instrument of transfer satisfactory to the Trustee. Upon such transfer, a new fully registered bond or bonds of authorized denomination or denominations for the same aggregate principal amount and maturity will be issued to the transferee in exchange therefor, all upon payment of the charges and subject to the terms and conditions set forth in this Indenture. The Authority and the Trustee may deem and treat the person in whose name this Bond is registered as the absolute owner hereof, whether or not this Bond shall be overdue, for the purpose of receiving payment (except as provided above with respect to Regular and Special Record Dates) and for all other purposes, and neither the Authority nor the Trustee shall be affected by any notice to the contrary. Bonds which are reissued upon transfer, exchange or other replacement shall bear interest from the most recent Interest Payment Date to which interest has been paid or duly provided for, or if no interest has been paid, then from the Original Issue Date.

To the extent permitted by, and as provided in the Indenture, modifications or amendments of the Indenture, or of any indenture supplemental thereto, and of the rights and obligations of the Authority and of the owners of the Bonds may be made with the consent of the Authority and, in certain instances, with the consent of the owners of not less than a majority in aggregate principal amount of the Bonds then Outstanding; provided, however, that no such modification or amendment shall be made which will affect the terms of payment of the principal of, premium, if any, or interest on any of the Bonds which are unconditional, unless consented to by all Bondholders. Any such consent by the owner of this Bond shall be conclusive and binding upon such owner and upon all future owners of this Bond and of any bond issued upon the transfer or exchange of this Bond whether or not notation of such consent is made upon this Bond.

The owner of this Bond shall have no right to enforce the provisions of the Indenture, the provisions of which are incorporated herein by this reference, or to institute action to enforce the pledge, assignment or covenants made therein or to take any action with respect to an Event of Default under the Indenture or to institute, appear in or defend any suit, action or other proceeding at law or in equity with respect thereto, except as provided in this Indenture. In case an Event of Default under the Indenture shall occur, the principal of all the Bonds at any such time Outstanding under the Indenture may be declared or may become due and payable, upon the conditions and in the manner and with the effect provided in this Indenture. The Indenture provides that such declaration may in certain events be rescinded and annulled by the Trustee under certain circumstances.

Neither the members of the Authority nor any person 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.

It is hereby certified, recited and declared that all conditions, acts and things required by the Constitution or statutes of the State of Oklahoma or by the Act or the Indenture to exist, to have happened or to have been performed precedent to or in the issuance of this Bond exist, have happened and have been performed.

This Bond shall not be entitled to any benefit under this Indenture or any indenture supplemental thereto, or become valid or obligatory for any purpose until the Trustee shall have signed the certificate of authentication hereon.

IN WITNESS WHEREOF, Adair County Industrial Authority has caused this Bond to be signed in its name and on its behalf by the manual or facsimile signature of its Chairman, and a facsimile of its corporate seal to be affixed hereon and attested by the manual or facsimile signature of its Secretary.

ARTICLE II

AUTHORIZATION, TERMS,

Section 2.01. Authorized Amount of Bonds. No Bonds may be issued under this Indenture except in accordance with this Article. The total principal amount of Bonds that may be issued hereunder is hereby expressly limited to, and the amount hereby authorized to be issued shall be, $13,515,000.

Section 2.02. All Bonds Equally and Ratably Secured by Trust Estate Except as Expressly Provided Herein; Limited Obligation of Bonds and Pledges Securing the Same. All Bonds issued under this Indenture and at any time Outstanding shall in all respects be equally and ratably secured hereby, without preference, priority or distinction as to date or dates or the actual time or times of the issue or maturity of the Bonds, so that all Bonds at any time issued and Outstanding hereunder shall have the same right, Lien and preference under and by virtue of this Indenture, and shall all be equally and ratably secured hereby, except as otherwise expressly provided herein.

The Bonds shall be special, limited revenue obligations of the Authority payable solely out of the security specified in this Indenture. The Bond shall not constitute or become an indebtedness, a debt or a liability of or a charge against the general credit or taxing power of the State of Oklahoma or any political subdivision thereof, including the County, but shall constitute a special, limited revenue obligation of the Authority only payable solely from and only to the extent of the Trust Estate pledged in the Indenture, and neither the State of Oklahoma, nor any political subdivision thereof, including the County, shall be liable thereon; nor shall the Bonds constitute the giving, pledging, or loaning of the faith and credit of the State of Oklahoma, or any political subdivision thereof, including the County. The issuance of the Bonds shall not, directly or indirectly or contingently, obligate the State of Oklahoma or any political subdivision thereof, including the County, to levy or collect any form of taxes or assessments therefor or to create any indebtedness payable out of taxes or assessments or make any appropriation for the payment of the Bonds, and such appropriation or levy is prohibited. The Authority has no taxing power.

Nothing in the Act shall be construed to authorize the Authority to create a debt of the State of Oklahoma within the meaning of the Constitution or statutes of the State of Oklahoma or authorize the Authority to levy or collect taxes or assessments. Neither the members of the Authority nor any person 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. The State of Oklahoma shall not in any event be liable for the payment of the principal of, premium, if any, or interest on the Bonds or for the performance of any pledge, mortgage, obligation or agreement of any kind whatsoever undertaken by the Authority. No breach of any such pledge, mortgage, obligation or agreement shall impose any pecuniary liability upon the State of Oklahoma or any charge upon its general credit or against its taxing power.

Section 2.03. Authorization of Bonds. There is hereby authorized to be issued hereunder and secured hereby an issue of bonds, designated as the “Adair County Industrial Authority Solid Waste Recovery Facilities Revenue Bonds (Advanced Environmental Recycling Technologies, Inc Project) Series 2007.” They shall be issuable only as fully registered bonds in

the minimum denomination of $100,000 plus integral multiples of $5,000 in excess thereof. The Bonds shall be separately lettered “R” and shall be numbered separately from 1 upward.

The Bonds shall be dated as of their date of original issuance, and shall bear interest from such date to maturity at the rate of 8.00% per annum, on the basis of a 360-day year composed of twelve 30-day months, payable semiannually on June 15 and December 15 of each year, with the first interest payment to be made on June 15, 2008, except that Bonds which are reissued upon transfer, exchange or other replacement shall bear interest from the most recent Interest Payment Date to which interest has been paid, or if no interest has been paid, from the date of original issuance of the Bonds.

The Bonds shall be originally issued in Book-Entry Form, and shall be registered in the name of Cede & Co., as nominee of The Depository Trust Company. While the Bonds are held in Book-Entry Form, (a) such Bonds shall be registered in the name of the Depository or its nominee, as Bondholder, and immobilized in the custody of the Depository; (b) unless otherwise requested by the Depository, there shall be a single Bond certificate for each Bond maturity; and (c) such Bonds shall not be transferable or exchangeable, except for transfer to another Depository or another nominee of a Depository, without further action by the Authority. While the Bonds are in Book-Entry Form, Bonds in the form of physical certificates shall only be delivered to the Depository.

So long as a book-entry system is in effect for the Bonds, the Authority and Trustee shall recognize and treat the Depository, or its nominee, as the holder of the Bonds for all purposes, including payment of debt service, giving of notices, and enforcement of remedies. The crediting of payments of debt service on the Bonds and the transmittal of notices and other communications by the Depository to the Direct Participant in whose Depository account the Bonds are recorded and such crediting and transmittal by Direct Participants to Indirect Participants or Beneficial Owners and by Indirect Participants to Beneficial Owners are the respective responsibilities of the Depository and the Direct Participants and the Indirect Participants and are not the responsibility of the Authority or the Trustee; provided, however, that the Authority and the Trustee understand that neither the Depository nor its nominee shall provide any consent requested of the Registered Owners of Bonds pursuant to this Indenture, and that the Depository will mail an omnibus proxy (including a list identifying the Direct Participants) to the Authority which assigns the Depository’s, or its nominee’s, voting rights to the Direct Participants to whose account at the Depository the Bonds are credited (as of the record date for mailing of requests for such consents). Upon receipt of such omnibus proxy, the Authority shall promptly provide such omnibus proxy (including the list identifying the Direct Participants attached thereto) to the Trustee, who shall then treat such owners as Registered Owners of the Bonds for purposes of obtaining any consents pursuant to the terms of this Indenture.

As long as the Bonds are registered in the name of a Depository, or its nominee, the Trustee agrees to comply with the terms and provisions of the Letter of Representations including the provisions of the Letter of Representations with respect to any delivery of the Bonds to the Trustee shall supersede the provisions of this Indenture with respect thereto.

If any Depository determines not to continue to act as a Depository for the Bonds held in a book-entry system, the Authority may attempt to have established a securities depository/book-entry system relationship with another Depository under this Indenture. If the Authority does not or is unable to do so, the Authority and the Trustee, after the Trustee has made provision for notification of the Beneficial Owners by appropriate notice to the then Depository, shall permit withdrawal of the Bonds from the Depository and shall authenticate and deliver Bonds certificates in fully registered form to the assignees of the Depository or its nominee or to the Beneficial Owners. A majority of the Beneficial Owners also may request that the Bonds be withdrawn from the Depository and that the Trustee authenticate and deliver Bonds certificates in fully registered form to the Beneficial Owners. Such withdrawal, authentication and delivery shall be at the cost and expense (including costs of printing or otherwise preparing and delivering such replacement Bonds) of the Company. Such replacement Bonds shall be in the denominations specified in the first paragraph of this Section 2.03.

NEITHER THE COUNTY, THE COMPANY NOR THE TRUSTEE WILL HAVE ANY RESPONSIBILITY OR OBLIGATION TO ANY DIRECT PARTICIPANT, INDIRECT PARTICIPANT OR ANY BENEFICIAL OWNER OR ANY OTHER PERSON NOT SHOWN ON THE REGISTRATION BOOKS OF THE TRUSTEE AS BEING A HOLDER WITH RESPECT TO: (A) THE SERIES 2007 BONDS; (B) THE ACCURACY OF ANY RECORDS MAINTAINED BY DTC OR ANY DIRECT PARTICIPANT OR INDIRECT PARTICIPANT; (C) THE TIMELY OR ULTIMATE PAYMENT BY DTC OR ANY DIRECT PARTICIPANT OR INDIRECT PARTICIPANT OF ANY AMOUNT DUE TO ANY BENEFICIAL OWNER IN RESPECT OF THE PRINCIPAL OR REDEMPTION PRICE OF OR INTEREST ON THE BONDS; (D) THE DELIVERY BY ANY DIRECT PARTICIPANT OR INDIRECT PARTICIPANT OF ANY NOTICE TO ANY BENEFICIAL OWNER WHICH IS REQUIRED OR PERMITTED UNDER THE TERMS OF THIS INDENTURE TO BE GIVEN TO REGISTERED OWNERS; (E) THE SELECTION OF THE BENEFICIAL OWNERS TO RECEIVE PAYMENT IN THE EVENT OF ANY PARTIAL REDEMPTION OF THE BONDS; OR (F) ANY CONSENT GIVEN OR OTHER ACTION TAKEN BY DTC AS HOLDER.

The Bonds shall mature on December 15, 2023.

Proceeds of the Bonds shall be applied as provided in the Indenture and the Loan Agreement.

The principal of and premium, if any, on the Bonds shall be payable at the designated corporate trust office of the Trustee currently located in Oklahoma City, Oklahoma, or at the principal office of its successor in trust upon presentation and surrender of the Bonds. Payment of interest on any Bond shall be made to the Registered Owner thereof by check or draft mailed on the Interest Payment Date by the Trustee to the Registered Owner at his address as it last appears on the registration books kept by the Trustee at the close of business on the Regular Record Date for such Interest Payment Date, but any such interest not so timely paid or duly provided for shall cease to be payable to the Registered Owner thereof at the close of business on the Regular Record Date and shall be payable to the Registered Owner thereof at the close of business on a Special Record Date for the payment of any such defaulted interest. Such Special Record Date shall be fixed by the Trustee whenever monies become available for payment of the

defaulted interest, and notice of such Special Record Date shall be given to the Registered Owners of the Bonds not less than 10 days prior thereto by first-class mail to each such Registered Owner as shown on the Trustee’s registration books on the date selected by the Trustee, stating the date of the Special Record Date and the date fixed for the payment of such defaulted interest. Notwithstanding the foregoing, at the written request addressed to the Trustee by any Bondholder of at least $1,000,000 in aggregate principal amount of the Bonds, payments of principal at maturity or upon redemption and payments of interest may be paid by wire transfer within the United States to the bank account number filed no later than the Regular Record Date with the Trustee for such purpose. All payments on the Bonds shall be made in lawful money of the United States of America upon collection of immediately available funds.

The Bonds are subject to prior redemption as herein set forth. The Bonds shall be substantially in the form and tenor hereinabove recited with such appropriate variations, omissions and insertions as are permitted or required by this Indenture.

Notwithstanding anything herein to the contrary, when any Bond is registered in the name of a Depository or its nominee, the principal and redemption price of and interest on such Bond shall be payable in same day or federal funds delivered or transmitted to the Depository or its nominee.

Section 2.04. Execution of Bonds. The Bonds shall be executed in the name and on behalf of the Authority, by the manual or facsimile signature of the Chairman of the Authority, and its corporate seal or a facsimile thereof shall be thereunto affixed, imprinted, engraved or otherwise reproduced thereon and attested by the manual or facsimile signature of its Secretary. Any Bond may be signed (manually or by facsimile), sealed or attested on behalf of the Authority by any person who, at the date of such act, shall hold the proper office, notwithstanding that at the date of authentication, issuance or delivery, such person may have ceased to hold such office.

Section 2.05. Registration, Transfer and Exchange of Bonds, Persons Treated as Owner. The Authority shall cause books for the registration and for the transfer of the Bonds as provided in this Indenture to be kept by the Trustee which is hereby appointed the transfer agent of the Authority for the Bonds. Notwithstanding such appointment, the Trustee is hereby authorized to make any arrangements with other institutions that it deems necessary or desirable in order that such institutions may perform the duties of transfer agent for the Bonds. Subject to the provisions of Section 2.03 hereof, upon surrender for transfer of any Bond at the designated corporate trust office of the Trustee, duly endorsed for transfer or accompanied by an assignment duly executed by the Registered Owner or his attorney duly authorized in writing, the Authority shall execute and the Trustee shall authenticate and deliver in the name of the transferee or transferees a new fully registered Bond or Bonds for a like aggregate principal amount of the same maturity.

Bonds may be exchanged at the designated corporate trust office of the Trustee for a like aggregate principal amount of fully registered Bonds of the same maturity in authorized denominations, which shall be no less than $100,000. The Authority shall execute and the Trustee shall authenticate and deliver Bonds which the Bondholder making the exchange is entitled to receive, bearing numbers not contemporaneously Outstanding. The execution by the

Authority of any fully registered Bond of any denomination shall constitute full and due authorization of such denomination and the Trustee shall thereby be authorized to authenticate and deliver such fully registered Bond.

The Trustee shall not be required to transfer or exchange any Bond during the period from the Regular Record Date next preceding the mailing of notice of redemption as herein provided. After the giving of such notice of redemption, the Trustee shall not be required to transfer or exchange any Bond, which Bond or portion thereof has been called for redemption.

Payment of either principal or interest on any fully registered Bond shall be made only to or upon the written order of the Registered Owner thereof or his legal representative, on the payment date for the principal and on the Regular Record Date or the Special Record Date for the payment of interest but such registration may be changed as hereinabove provided. All such payments shall be valid and effectual to satisfy, and discharge the liability upon such Bond to the extent of the sum or sums paid. As to any Bond, for all other purposes and on any other date, the Registered Owner shall be regarded as the absolute owner hereof.

The Trustee shall require the payment by any Bondholder requesting exchange or transfer of any tax or other governmental charge required to be paid with respect to such exchange or transfer. The Company shall, under the Loan Agreement, be liable to pay all expenses and charges of the Authority and of the Trustee in connection with such exchange or transfer.

Section 2.06. Lost, Stolen, Destroyed and Mutilated Bonds. Upon receipt by the Authority and the Trustee of evidence satisfactory to them of the ownership of and the loss, theft, destruction or mutilation of any Bond and, in the case of a lost, stolen or destroyed Bond, of indemnity satisfactory to them, and upon surrender and cancellation of the Bond, if mutilated, (a) the Authority shall execute, and the Trustee shall authenticate and deliver, a new Bond of the same maturity, series and denomination in lieu of such lost, stolen, destroyed or mutilated Bond; or (b) if such lost, stolen, destroyed or mutilated Bond shall have matured or have been called for redemption, in lieu of executing and delivering a new Bond as aforesaid, the Authority may pay such Bond. Any such new Bond shall bear a number not contemporaneously Outstanding. The applicant for any such new Bond may be required to pay all expenses and charges of the Authority and of the Trustee in connection with the issuance of such Bond. All Bonds shall be held and owned upon the express condition that, to the extent permitted by law, the foregoing conditions are exclusive with respect to the replacement and payment of mutilated, destroyed, lost or stolen Bonds.

Section 2.07. Delivery of Bonds. Upon the execution and delivery of this Indenture, the Authority shall execute and deliver to the Trustee and the Trustee shall authenticate the Bonds and deliver them to the initial purchasers thereof as directed by the Authority and as hereinafter in this Section provided.

(a) the Resolution duly adopted by the Authority, certified by its Secretary or other Authority Officer thereof, authorizing the financing of the Cost of the Project, the execution and delivery of the Loan Agreement and this Indenture and the issuance of the Bonds;

(b) a duly executed copy of this Indenture;

(d) the written order of the Authority as to the delivery of the Bonds signed by an Authority Officer.

Section 2.08. Trustee’s Authentication Certificate. The Trustee’s authentication certificate upon the Bonds shall be substantially in the form and tenor hereinbefore provided. No Bond shall be secured hereby or entitled to the benefit hereof, or shall be valid or obligatory for any purpose, unless the certificate of authentication, substantially in such form, has been duly executed by the Trustee; and such certificate of the Trustee upon any Bond shall be conclusive evidence and the only competent evidence that such Bond has been authenticated and delivered hereunder. The Trustee’s certificate of authentication shall be deemed to have been duly executed by it if manually signed by an authorized officer of the Trustee, but it shall not be necessary that the same person sign the signed certificate of authentication on all of the Bonds issued hereunder.

Section 2.09. Cancellation and Destruction of Bonds by the Trustee. Whenever any Outstanding Bonds shall be delivered to the Trustee for the cancellation thereof pursuant to this Indenture, upon payment of the principal amount or interest represented thereby, or for replacement pursuant to Section 2.06 hereof, such Bonds shall be promptly canceled and destroyed by the Trustee and counterparts of a certificate of destruction evidencing such destruction shall be furnished by the Trustee to the Authority and the Company.

Section 2.10. Temporary Bonds. Pending the preparation of definitive Bonds, the Authority may execute and the Trustee shall authenticate and deliver temporary Bonds. Temporary Bonds shall be issuable as fully registered Bonds without coupons, of any denomination, and substantially in the form of the definitive Bonds but with such omissions, insertions and variations as may be appropriate for temporary Bonds, all as may be determined by the Authority. Every temporary Bond shall be executed by the Authority and be authenticated by the Trustee upon the same conditions and in substantially the same manner, and with like effect, as the definitive Bonds. As promptly as practicable the Authority shall execute and shall furnish definitive Bonds and thereupon temporary Bonds may be surrendered in exchange therefor at the designated office of the Trustee and the Trustee shall authenticate and deliver in exchange for such temporary Bonds a like aggregate principal amount of definitive Bonds. Until so exchanged the temporary Bonds shall be entitled to the same benefits under this Indenture as definitive Bonds.

Section 2.11. Transfer Restrictions. Upon a transfer of a Beneficial Ownership Interest in a Series 2007 Bond (other than a transfer by the Underwriter pursuant to the initial sale of the Series 2007 Bonds), each purchaser of such Beneficial Ownership Interest shall be

deemed to have certified to the Trustee and acknowledged, represented and agreed with the Company and the Underwriter that such purchaser is acquiring the Series 2007 Bond for its own account, and that it is (a) a “qualified institutional buyer” within the meaning of Rule 144A promulgated under the Securities Act of 1933, as amended, or (b) an institutional “accredited investor,” as defined in Rule 501(a)(1), (2), (3), or (7) of the Securities Act of 1933, as amended.

The Trustee shall invest the Rebate Fund at the written direction (or by oral instruction promptly confirmed in writing) of the Company Representative and shall deposit income from said investments immediately upon receipt thereof in the Rebate Fund. For purposes of determining rebate calculations that may be required with respect thereto pursuant to the Tax Certificate, the Company shall employ, at its own expense, a Rebate Analyst. The Tax Certificate may be superseded or amended by a certificate of the Company, accompanied by an Opinion of Bond Counsel addressed to the Company and the Trustee to the effect that the use of said Company certificate will not adversely affect the exclusion of interest on the Bonds from gross income of the recipients thereof for purposes of federal income taxation.

Section 3.16. Rebate Deposits. The Trustee shall make the rebate deposit described in the Tax Certificate based upon the written instructions of the Company Representative. If a withdrawal from the Rebate Fund is permitted as a result of such computation because no rebate payments are required to be made, the amount withdrawn shall be deposited in the Bond Principal Fund in accordance with written instructions furnished to the Trustee. Record of the determinations required by this Section must be retained by the Company Representative and the Trustee until six years after the final retirement of the Bonds.

If the monies on deposit in the Rebate Fund are insufficient for the purposes thereof, the Trustee shall transfer monies to the Rebate Fund from the following Funds in the following order of priority: the Project Fund, the Reserve Fund, the Bond Principal Fund and the Bond Interest Fund.

Section 3.17. Rebate Disbursements. Not later than 60 days after the last day of the fifth Bond Year, as defined in the Tax Certificate, and every five years thereafter, the Trustee shall pay to the United States 90% of the amount, at the written direction of the Rebate Analyst, on deposit in the Rebate Fund as of such payment date. No later than 60 days after the final retirement of the Bonds, the Trustee shall pay to the United States 100% of the balance remaining in the Rebate Fund (or such lesser amount as shall be due and owing to the United States). Nothing herein shall relieve the Company of its obligation to pay the rebate amount in accordance with Section 5.01(g) of the Loan Agreement. Each payment required to be paid to the United States pursuant to this Section shall be filed with the Internal Revenue Service Center,

Ogden, UT 84201. Each payment shall be accompanied by a copy of the Internal Revenue Form 8038 originally filed with respect to the Bonds, Internal Revenue Form 8038-T and, if necessary, a statement summarizing the determination of the amount to be paid to the United States.

Section 3.18. Tax Certificate. The use and investment of monies in any of the Funds shall be subject to the provisions of the Tax Certificate, and the Authority and the Trustee, in the performance of their duties thereunder, agree to comply with the same.

The Trustee shall keep and maintain adequate records pertaining to the Cost of Issuance Fund, and all payments therefrom, which shall be open to inspection by the Company, Registered Owners of the Bonds, the Beneficial Owners or their duly authorized agents during normal business hours of the Trustee.

Section 3.22. Capitalized Interest Fund. The Company shall deposit to the Capitalized Interest Fund an amount equal to $497,031 (equivalent to 6 months of interest on the Bonds) from the proceeds of the Bonds. An amount equal to the interest due on the Bonds shall be transferred from the Capitalized Interest Fund to the Bond Interest Fund on each Interest Payment Date until the Capitalized Interest Fund is exhausted. Upon the occurrence of an Event of Default hereunder and the exercise by the Trustee of the remedy specified in Section 10.02 of the Loan Agreement and Section 8.02 hereof, any moneys in the Capitalized Interest Fund shall be transferred by the Trustee to the Bond Principal Fund.

Amounts on deposit in the Capitalized Interest Fund shall be: (a) held in trust solely for the benefit of the Registered Owners and (b) applied only in accordance with the provisions of this Indenture.

Section 5.01. Redemption of Bonds Upon Occurrence of Certain Events.

(a) The Bonds are redeemable by the Authority upon the direction of the Company Representative in whole or in part at any time at a redemption price equal to the principal amount of each Bond redeemed, and accrued but unpaid interest thereon to the redemption date, upon the occurrence of events described in Section 7.01 of the Loan Agreement.

(b) The Bonds are also redeemable by the Authority upon the direction of the Company Representative in whole but not in part at any time at a redemption price equal to 110% of the principal amount thereof, and accrued but unpaid interest thereon to the redemption date, as a condition precedent to the acquisition by any Person of

substantially all of the assets of the Company or as a condition precedent of the merger or consolidation of the Company, as provided in Section 8.14 of the Loan Agreement.

Section 5.02. Redemption of Bonds Upon a Determination of Taxability. Upon the occurrence of a Determination of Taxability, the Bonds are subject to mandatory redemption in whole at a redemption price equal to 105% of the Outstanding principal amount thereof, plus interest accrued to redemption date, at the earliest practicable date selected by the Trustee, after consultation with the Company, but in no event later than 45 days following the Trustee’s notification of the Determination of Taxability. The occurrence of a Determination of Taxability with respect to the Bonds will not constitute an Event of Default under this Indenture and the sole remedy of the holders will be mandatory redemption of the Bonds in accordance with this Section 5.02. Within five Business Days after receipt by the Trustee of written notice of a Determination of Taxability, the Trustee shall give written notice thereof to the holders of all Bonds then Outstanding and shall also give written notice to the Company and the Authority.

Section 5.03. Sinking Fund. The Bonds are subject to mandatory sinking fund redemption at a redemption price equal to 100% of the principal amount thereof and accrued but unpaid interest to the redemption date. As and for a sinking fund for the redemption of such Bonds, there shall be deposited pursuant to Section 5.01(a) of the Loan Agreement in the Bond Principal Fund and Bond Interest Fund a sum which is sufficient to redeem (after credit as provided below) the following principal amounts of such Bonds and accrued but unpaid interest to the redemption date:

2021		1,417,800
2022		1,467,600
2023		1,518,400

Not more than 45 days nor less than 30 days prior to a sinking fund payment date for the Bonds, the Trustee shall proceed to select for redemption (by lot in such manner as the Trustee may determine) from all Bonds Outstanding which are subject to sinking fund redemption on such date a principal amount of such Bonds equal to the aggregate principal amount of Bonds

redeemable with the required sinking fund payment, and shall call such Bonds for redemption from the particular sinking fund on the next December 15, and give notice of such call.

At the option of the Company Representative (so long as no Event of Default has occurred and is continuing) to be exercised by delivery of a written certificate to the Trustee and the Authority not less than 45 days next preceding any sinking fund redemption date, it may (a) deliver to the Trustee for cancellation Bonds which are subject to sinking fund redemption on such date in an aggregate principal amount designated by the Company Representative; or (b) specify a principal amount of such Bonds which prior to said date have been redeemed (otherwise than through the operation of such sinking fund) and canceled by the Trustee and not theretofore applied as a credit against any sinking fund redemption obligation for such Bonds. Each Bond so delivered or previously redeemed shall be credited by the Trustee at 100% of the principal amount thereof against the obligation of the Company on such sinking fund redemption date, and any excess shall be so credited against future sinking fund redemption obligations for Bonds proportionately to all remaining sinking fund payments. In the event the Company Representative shall avail itself of the provisions of clause (a) of the first sentence of this paragraph the certificate required by the first sentence of this paragraph shall be accompanied by the Bonds to be canceled.

Notwithstanding any provision of this Indenture to the contrary, in the event all Bonds are held by a single holder, no additional notice shall be required with respect to mandatory sinking fund redemption unless requested by the holders of 100% of the principal amount of the Bonds, and Bonds need not be presented for mandatory sinking fund redemption payment.

Section 5.04. Method of Selecting Bonds. Except in the case of mandatory sinking fund redemption pursuant to Section 5.03 hereof, in the event that less than all of the Outstanding Bonds shall be redeemed, the Bonds redeemed shall be redeemed in such order of maturity as the Company Representative shall determine in accordance with written directions furnished to the Trustee (less than all of the Bonds of a single maturity to be selected by lot in such manner as the Trustee may determine).

Section 5.05. Notice of Redemption. Bonds shall be called for redemption by the Trustee as herein provided but only if funds have been deposited with the Trustee on or before the date fixed for redemption sufficient to pay the applicable redemption price of the Bonds to be redeemed. Except as otherwise herein provided, the Company shall provide to the Trustee, at least 45 days prior to the redemption date, a certificate of the Company Representative specifying the principal amount of the Bonds to be called for redemption, the applicable redemption price or prices and the provision or provisions of this Indenture pursuant to which such Bonds are to be called for redemption, provided that such certificate shall not be required with respect to a sinking fund redemption pursuant to Section 5.03 hereof and Bonds shall be called for redemption by the Trustee pursuant to such Section without the necessity of any action by the Authority or the Company. In the case of any redemption or tender other than as provided in Section 5.03 hereof, the Trustee shall cause notice of such redemption to be given by mailing not more than 45 days nor less than 30 days prior to the redemption date by first class mail a copy of the redemption notice to the Registered Owner of any Bonds designated for redemption in whole or in part, at their address as the same shall last appear upon the registration books; provided, however, that failure to give such notice or any defect therein, shall not affect the

validity of any proceedings for the redemption of such Bonds for which no such failure or defect occurs.

Notice of any redemption hereunder with respect to Bonds held under a book-entry system shall be given by the Trustee only to the Depository, or its nominee, as the holder of such Bonds. Selection of book-entry interests in the Bonds called for redemption, and notice of call to the owners of those interests called, is the responsibility of the Depository, the Direct Participants and the Individual Participants and any failure of the Depository to advise any Direct Participant and any failure of a Direct Participant or any Indirect Participant to notify the Beneficial Owner of any such notice and its contents or effect will not affect the validity of such notice of any proceedings for the redemption of such Bonds.

Each notice of redemption shall specify the name of the Bonds, the date the Bonds were originally issued, the date fixed for redemption, the date of mailing of the notice, the redemption price, the place or places of payment (including contact person and phone number), the CUSIP numbers of Bonds being redeemed, the rate of interest borne by each Bond being redeemed, the maturity date of each Bond being redeemed, that payment will be made upon presentation and surrender of the Bonds to be redeemed, that unpaid interest accrued to the date fixed for redemption will be paid as specified in said notice, any conditions to the redemption (including, but not limited to, deposit of the applicable redemption price) and that on and after said date interest thereon will cease to accrue. If less than all the Outstanding Bonds are to be redeemed, the notice of redemption shall specify the Bonds to be redeemed, and the numbers of the Bonds or portions thereof to be redeemed.

Section 5.06. Bonds Due and Payable on Redemption Date; Interest Ceases to Accrue. On or before any redemption pursuant to this Article V, collected funds sufficient to redeem all the Bonds called for redemption at the appropriate redemption price, including accrued but unpaid interest to the date fixed for redemption, shall be deposited with the Trustee. On the redemption date, the principal amount of each Bond to be redeemed, together with the accrued but unpaid interest thereon to such date, and premium, if any, shall become due and payable; from and after such date, notice of redemption having been given, and deposit having been made in accordance with the provisions of this Article V, then, notwithstanding that any Bonds called for redemption shall not have been surrendered, no further interest shall accrue on any of such Bonds. From and after such date of redemption (such notice having been given and such deposit having been made), the Bonds to be redeemed shall not be deemed to be Outstanding hereunder, and the Authority shall be under no further liability in respect thereof.

Section 5.07. Cancellation. All Bonds which have been redeemed shall be canceled by the Trustee and destroyed as provided in Section 2.09 hereof.

Section 5.08. Partial Redemption of Bonds. Upon surrender of any Bond for redemption in part only, the Authority shall execute, and the Trustee shall authenticate and deliver to the owner thereof, the cost of which shall be paid by the Company, a new Bond or Bonds of the same maturity and of authorized denominations, in an aggregate principal amount equal to the unredeemed portion of the Bond surrendered; provided that the Trustee shall select Bonds for redemption so as to assure that after such redemption no Registered Owner or owner of Beneficial Interests shall retain Bonds in authorized denominations of not less than $100,000;

and provided further that, if less than all of an Outstanding Bond of one maturity in a book-entry system is to be called for redemption, the Trustee shall give notice to the Depository or the nominee of the Depository that is the holder of such Bond, and the selection of the Beneficial Interests in that Bond to be redeemed shall be at the sole discretion of the Depository and its participants. In the case of a partial redemption of Bonds by lot, each unit of face value of principal thereof equal to $5,000 (each such $5,000 unit is hereinafter referred to as a “Unit”) shall be treated as though it were a separate Bond in the amount of such Unit. If it is determined that one or more, but not all, of the Units represented by a Bond are to be called for redemption, then upon notice of redemption of a Unit or Units of Bonds, the holder of that Bond shall surrender the Bond to the Trustee (a) for payment of the redemption price of the Unit or Units of Bonds called for redemption (including without limitation the unpaid interest accrued to the date fixed for redemption and any premium); and (b) for issuance, without charge to the holder thereof, of a new Bond or Bonds of $100,000 or amounts in excess thereof in such integrals as are permitted hereunder, aggregating a principal amount equal to the unmatured and unredeemed portion of, and bearing interest at the same rate and maturing on the same date as, the Bond surrendered.

ARTICLE VI

As to any investment agreement, the Trustee shall give notice to any provider of an investment agreement in accordance with the terms of the investment agreement so as to receive funds thereunder when needed with no penalty or premium paid.

Section 6.02. Arbitrage. In reliance upon the covenant of the Company in Section 4.06 of the Loan Agreement, the Authority hereby covenants for the benefit of each owner of the Bonds that no use will be made of the proceeds of the Bonds or of any monies in the Funds and that no other action shall be taken which will cause the Bonds or any obligations subsequently issued by the Authority to be “arbitrage bonds” within the meaning of Section 148 of the Code and the regulations prescribed thereunder.

Unless otherwise required by Section 148 of the Code, the Chairman or any other officer of the Authority having responsibility with respect to the issuance of the Bonds shall, on or prior to the date of issuance of the Bonds, if applicable, either alone or in conjunction with any other officer, employee, consultant or agent of the Authority, deliver to the Trustee the certification required by the regulations promulgated under Section 148 of the Code to evidence that such Bonds will not be “arbitrage bonds” within the meaning of Section 148 of the Code and the regulations thereunder. Such certificates may rely upon the certificates of the Company delivered to the Authority pursuant to Section 4.06 of the Loan Agreement.

Section 6.03. Allocation and Transfers of Investment Income. Any investments shall be held by or under the control of the Trustee and shall be deemed at all times a part of the Fund from which the investment was made. Any loss resulting from such investments shall be charged to such Fund.

(d) any interest or other gain realized as a result of any investments or reinvestments of moneys in the Cost of Issuance Fund shall be paid to the Company;

(e) any interest or other gain realized as a result of any investment or reinvestment of moneys in the Rebate Fund shall be retained in the Rebate Fund; and

If, when the Bonds secured hereby shall be paid in accordance with their terms (or payment of the Bonds has been provided for in the manner set forth in the following paragraph), together with all other sums payable hereunder, then this Indenture and the Trust Estate and all rights granted hereunder shall thereupon cease, terminate and become void and be discharged and satisfied.

The Trustee shall be entitled as a matter of right without notice or demand (such notice being expressly waived hereby), ex parte, to the appointment of a receiver or receivers of the Trust Estate, and of the rents, revenues, income, products and profits thereof, pending such proceedings, but, notwithstanding the appointment of any receiver, trustee or other custodian, the Trustee shall be entitled to the possession and control of any cash, securities or other instruments at the time held by, or payable or deliverable under the provisions of this Indenture to, the Trustee.

(d) Suit for Judgment on the Bonds. The Trustee shall be entitled to sue for and recover judgment, either before or after or during the pendency of any proceedings for the enforcement of the Lien of this Indenture, for the enforcement of any of its rights, or the rights of the Bondholders hereunder, but any such judgment against the Authority shall be enforceable only against the Trust Estate. No recovery of any judgment by the Trustee shall in any manner or to any extent affect the Lien of this Indenture or any rights, powers or remedies of the Trustee hereunder, or any Lien, rights, powers or remedies of the owners of the Bonds, but such Lien, rights, powers and remedies of the Trustee or the Bondholders shall continue unimpaired as before.

In the event written notice is given by the Bondholders to the Trustee under Section 8.01(c) hereof and upon due receipt of such notice by the Trustee, the Trustee shall immediately give notice with respect to such default to the Company.

No right or remedy is intended to be exclusive of any other right or remedy, but each and every such right or remedy shall be cumulative with respect to the Trustee and the Bondholders, and in addition to any other right or remedy given hereunder or now or hereafter existing at law or in equity or by statute.

If any Event of Default shall have occurred and if instructed and directed in writing by the owners of not less than the sum of a majority in aggregate principal amount of Bonds then Outstanding and indemnified as provided in Section 9.01 hereof, the Trustee shall exercise such one or more of the rights and powers conferred by this Section as the Trustee, being advised by counsel, shall deem most expedient in the interests of the Bondholders or as may be set forth in such directions.

Section 8.03. Majority of Bondholders and Holders of Parity Indebtedness May Control Proceedings. Anything in this Indenture to the contrary notwithstanding and subject to prior notice to the Authority, the owners of the sum of a majority in aggregate principal amount of the Bonds and Parity Indebtedness then Outstanding shall have the right, at any time, to the extent permitted by law, by an instrument or instruments in writing executed and delivered to the Trustee, to direct the time, method and place of conducting all proceedings to be taken in connection with the enforcement of the terms and conditions of this Indenture, or for the appointment of a receiver, or any other proceedings hereunder; provided that such direction shall not be otherwise than in accordance with the provisions hereof. The Trustee shall not be required to act on any direction given to it pursuant to this Section unless indemnified as provided in Section 9.01 hereof.

Section 8.04. Rights and Remedies of Bondholders. No owner of any Bond or Parity Indebtedness shall have any right to institute any suit, action or proceeding in equity or at law for the enforcement of this Indenture or for the execution of any trust hereof or for the appointment of a receiver or any other remedy hereunder, unless a default has occurred of which the Trustee has been notified as provided in Section 9.01 hereof, or of which by said Section it is deemed to have notice, nor unless such default shall have become an Event of Default and the owners of the sum of not less than a majority in aggregate principal amount of Bonds then Outstanding shall have made written request to the Trustee and shall have offered within 10 days either to proceed to exercise the powers hereinbefore granted or to institute such action, suit or proceeding in its own name, nor unless they have also furnished to the Trustee indemnity as provided in Section 9.01 hereof nor unless the Trustee shall thereafter fail or refuse to exercise the powers hereinbefore granted, or to institute such action, suit or proceeding in its own name; and such notification, request and furnishing of indemnity are hereby declared in every case at the option of the Trustee to be conditions precedent to the execution of the powers and trusts of this Indenture, and to any action or cause of action for the enforcement of this Indenture, or for the appointment of a receiver or for any other remedy hereunder; it being understood and intended that no one or more owners of the Bonds shall have the right in any manner whatsoever to affect, disturb or prejudice the Lien of this Indenture by his, her or their action or to enforce any right hereunder except in the manner herein provided and that all proceedings at law or in equity shall be instituted, had and maintained in the manner herein provided and for the equal benefit of the owners of all Bonds then Outstanding. Nothing in this Indenture contained shall, however, affect or impair the right of any owner of Bonds to enforce the payment, by the institution of any suit, action or proceeding in equity or at law, of the principal of, premium, if any, or interest on any

Bond at and after the maturity thereof, or the obligation of the Authority to pay the principal of, premium, if any, and interest on each of the Bonds to the respective owners of the Bonds at the time and place, from the source and in the manner herein and in the Bonds expressed.

Section 8.05. Application of Monies. All monies received by the Trustee pursuant to any reasonable right given or action taken under the provisions of this Article shall, after payment of the fees of the Trustee, costs and expenses of the proceedings resulting in the collection of such monies and the expenses, liabilities and advances incurred or made by the Trustee, first, to the extent of any deficiency of required amounts in the Rebate Fund be deposited in the Rebate Fund, and thereafter shall be held in trust and all monies so deposited in the Bond Principal Fund and the Bond Interest Fund and all monies held or deposited in the Bond Principal Fund and the Bond Interest Fund during the continuance of an Event of Default shall be applied as follows:

(a) Unless the principal of all the Bonds and Parity Indebtedness shall have become or shall have been declared due and payable, all such monies shall be applied:

FIRST, to the payment to the Persons entitled thereto of all installments of interest then due on the Bonds and Parity Indebtedness in the order of the maturity of the installments of such interest and, if the amount available shall not be sufficient to pay in full any particular installment, then to the payment ratably, according to the amounts due on such installment, to the Persons entitled thereto, without any discrimination or privilege; and

SECOND, to the payment to the Persons entitled thereto of the unpaid principal of and premium, if any, on any of the Bonds and Parity Indebtedness which shall have become due (other than Bonds called for redemption for the payment of which moneys are held pursuant to the provisions of the Indenture), in the order of their due dates, with interest on the unpaid principal of and premium, if any, on such Bonds from the respective dates upon which they became due, at a rate which shall be the highest rate of interest borne by any such Bond and Parity Indebtedness during the 365 days prior to the date on which such Bonds and Parity Indebtedness became due or the maximum rate permitted by law if less than such rate aforesaid and, if the amount available shall not be sufficient to pay in full such Bonds and Parity Indebtedness due on any particular date, together with such interest, then to the payment ratably, according to the amount of principal due on such date, to the Persons entitled thereto, without any discrimination or privilege.

(b) If the principal of all the Bonds and Parity Indebtedness shall have become due or 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 all of the Bonds and such Parity Indebtedness, together with interest on overdue installments of principal at a rate which shall be the highest rate of interest borne by any Outstanding Bond during the 365 days prior to the date on which Bonds become due or the maximum rate permitted by law if less than such rate aforesaid, without preference or priority of principal over interest or of interest over principal, or of any installment of interest over any other installment of

interest, or of any such Bond over any other such Bond, ratably, according to the amounts due respectively for principal and interest, to the Persons entitled thereto without any discrimination or privilege.

(c) If the principal of all the Bonds and Parity Indebtedness shall have been declared due and payable, and if such declaration shall thereafter have been rescinded and annulled under the provisions of this Article then, subject to the provisions of paragraph (b) of this Section in the event that the principal of all the Bonds and Parity Indebtedness shall later become due or be declared due and payable, the monies shall be applied in accordance with the provisions of paragraph (a) of this Section .

Whenever monies are to be applied pursuant to the provisions of this Section, such monies shall be applied at such times, and from time-to-time, as the Trustee shall determine, having due regard to the amount of such monies available for application and the likelihood of additional monies becoming available for such application in the future. Whenever the Trustee shall apply such funds, it shall fix the date (which shall be an Interest Payment Date unless it shall deem another date more suitable) upon which such application is to be made, and upon such date interest on the amounts of principal to be paid on such dates shall cease to accrue. The Trustee shall give such notice as it may deem appropriate of the deposit of any such monies and of the fixing of any such date, and shall not be required to make payment to the owner of any Bond and Parity Indebtedness until such Bond and Parity Indebtedness shall be presented to the Trustee for appropriate endorsement or for cancellation if fully paid.

Whenever all of the Bonds and Parity Indebtedness and interest thereon have been paid under the provisions of this Section and all expenses and fees of the Trustee and all other amounts to be paid to the Authority hereunder or under the Loan Agreement have been paid, any balance remaining in the Funds shall be paid as provided in Section 3.13 hereof.

Section 8.06. Trustee May Enforce Rights Without Bonds. All rights of action and claims under this Indenture or any of the Bonds Outstanding hereunder may be enforced by the Trustee without the possession of any of the Bonds or the production thereof in any trial or proceedings relative thereto; and any suit or proceeding instituted by the Trustee shall be brought in its name as Trustee, without the necessity of joining as plaintiffs or defendants any owners of the Bonds, and any recovery of judgment shall be for the ratable benefit of the owners of the Bonds subject to the provisions of this Indenture.

Section 8.07. Trustee to File Proofs of Claim in Receivership, Etc. In the case of any receivership, insolvency, bankruptcy, reorganization, arrangement, adjustment, composition or other judicial proceedings affecting the Trust Estate or the Company, the Authority or the Trustee shall, to the extent permitted by law, be entitled to file such proofs of claims and other documents as may be necessary or advisable in order to have claims of the Trustee and of the Bondholders allowed in such proceedings for the entire amount due and payable by the Authority under this Indenture, or by the Company, as the case may be, at the date of the institution of such proceedings and for any additional amounts which may become due and payable by it after such date, without prejudice, however, to the right of any Bondholder to file a claim in his own behalf.

Section 8.08. Delay or Omission No Waiver. No delay or omission of the Trustee, any Bondholder or any holder to exercise any right or power accruing upon any default shall exhaust or impair any such right or power or shall be construed to be a waiver of any such default, or acquiescence therein; and every power and remedy given by this Indenture may be exercised from time-to-time and as often as may be deemed expedient.

Section 8.09. No Waiver of One Default to Affect Another. No waiver of any default hereunder, whether by the Trustee or the Bondholders, shall extend to or affect any subsequent or any other then existing default or shall impair any rights or remedies consequent thereon.

Section 8.10. Discontinuance of Proceedings on Default; Position of Parties Restored. In case the Trustee shall have proceeded to enforce any rights under this Indenture and such proceedings shall have been discontinued or abandoned for any reason, or shall have been determined adversely to the Trustee, then and in every such case the Authority and the Trustee shall be restored to their former positions and rights hereunder with respect to the Trust Estate, and all rights, remedies and powers of the Trustee shall continue as if no such proceedings had been taken.

Section 8.11. Waivers of Events of Default. Subject to prior written notice to and prior written consent of the Authority, the Trustee may in its discretion waive any Event of Default hereunder and its consequences and rescind any declaration of maturity of principal of and interest on the Bonds, and shall do so upon the written request of the owners of the sum of a majority in aggregate principal amount of all the Bonds then Outstanding in respect of which default exists; provided, however, that there shall not be waived (a) any Event of Default in the payment of the principal of or premium on any Outstanding Bonds at the date of maturity or redemption thereof, or any default in the payment when due of the interest on any such Bonds, unless prior to such waiver or rescission, all arrears of interest or all arrears of payments of principal and premium, if any (with interest upon such principal and premium, if any, at a rate which shall be 1% per annum above the highest rate of interest borne by any Bond during the 365 days prior to the date on which such principal and premium, if any, were due or the maximum rate permitted by law if less than such rate aforesaid) and all expenses of the Trustee, and all amounts to be paid to the Authority hereunder and under the Loan Agreement, in connection with such default shall have been paid or provided for; or (b) any default in the payment of amounts set forth in Section 5.01(d) of the Loan Agreement. In case of any such waiver or rescission, or in case any proceedings taken by the Trustee on account of any such default shall have been discontinued or abandoned or determined adversely to the Trustee, then and in every such case the Authority, the Trustee, the Bondholders shall be restored to their former positions and rights hereunder, respectively, but no such waiver or rescission shall extend to or affect any subsequent or other default, or impair any rights or remedies consequent thereon.

ARTICLE IX

CONCERNING THE TRUSTEE

Section 9.01. Duties of the Trustee. The Trustee hereby accepts the trusts imposed upon it by this Indenture and agrees to perform said trusts, but only upon and subject to the following express terms and conditions, and no implied covenants or obligations shall be read into this Indenture against the Trustee:

(a) The Trustee, prior to the occurrence of an Event of Default and after the curing of all Events of Default which may have occurred, undertakes to perform such duties and only such duties as are specifically set forth in this Indenture. In case an Event of Default has occurred (which has not been cured or waived), the Trustee shall exercise such of the rights and powers vested in it by this Indenture, and use the same degree of care and skill in their exercise, as a prudent man would exercise or use under the circumstances in the conduct of the affairs of others.

(b) The Trustee may execute any of the trusts hereof or powers hereunder and perform any of its duties by or through attorneys, agents, receivers or employees but shall be answerable for the conduct of the same in accordance with the standard specified above, only if the Trustee has not exercised reasonable care in the selection thereof and shall be entitled to act upon an opinion of independent counsel concerning all matters of the trust hereof and its duties hereunder, and may in all cases pay such reasonable compensation to all such attorneys, agents, receivers and employees as may reasonably be employed in connection with the trusts hereof. The Trustee may act upon an opinion of independent counsel and shall not be responsible for any loss or damage resulting from any action or nonaction taken by or omitted to be taken in good faith in reliance upon such opinion of independent counsel.

(c) The Trustee shall not be responsible for any recital herein or in the Bonds (except in respect to the certificate of authentication of the Trustee endorsed on the Bonds), or for insuring the Trust Estate or collecting any insurance monies or for the validity of the execution by the Authority of this Indenture or of any supplements hereto or instruments of further assurance, or for the sufficiency of the security for the Bonds issued hereunder or intended to be secured hereby, or for the value of or title to the assets of the Company and the Trustee shall not be bound to ascertain or inquire as to the performance or observance of any covenants, conditions or agreements on the part of the Authority, except as hereinafter set forth; but the Trustee may require of the Authority or the Company full information and advice as to the performance of the covenants, conditions and agreements as to the condition of the assets of the Company contained herein or in the Loan Agreement.

(e) The Trustee shall be protected in acting upon any notice, request, consent, certificate, order, affidavit, letter, telegram or other paper or document believed to be genuine and correct and to have been signed or sent by the proper person or persons. Any action taken by the Trustee pursuant to this Indenture upon the request or authority or consent of any person who at the time of making such request or giving such authority or consent is the owner of any Bonds shall be conclusive and binding upon all future owners of the same Bond and upon Bonds issued in place thereof.

(f) As to the existence or nonexistence of any fact or as to the sufficiency or validity of any instrument, paper or proceeding, the Trustee shall be entitled to rely upon a certificate signed on behalf of the Authority by an Authority Officer or such other person as may be designated for such purpose by the Authority as sufficient evidence of the facts therein contained, and prior to the occurrence of a default of which the Trustee has been notified as provided in subsection (h) of this Section, or of which by said subsection it is deemed to have notice, shall also be at liberty to accept a similar certificate to the effect that any particular dealing, transaction or action is necessary or expedient, but may at its discretion secure such further evidence deemed necessary or advisable, but shall in no case be bound to secure the same.

(g) The permissive rights of the Trustee to do things enumerated in this Indenture shall not be construed as a duty and the Trustee shall not be answerable for other than its negligence or willful default, subject to Section 9.01(a) hereof.

(h) The Trustee shall not be required to take notice or be deemed to have notice of any default hereunder except failure by the Authority to cause to be made any of the payments to the Trustee required to be made by Article III hereof unless the Trustee shall be specifically notified in writing of such default by the Authority or by the owners of at least 25% in aggregate principal amount of Bonds then Outstanding, and all notices or other instruments required by this Indenture to be delivered to the Trustee must, in order to be effective, be delivered at the designated corporate trust office of the Trustee; in the absence of such notice so delivered, the Trustee may conclusively assume that there is no default except as aforesaid.

(j) At any and all reasonable times, the Trustee, and its duly authorized agents, attorneys, experts, engineers, accountants and representatives, shall have the right, but shall not be required, to inspect any and all of the Trust Estate, including all books, papers and records of the Authority pertaining to the Project and the Bonds.

(k) The Trustee shall not be required to give any note or surety in respect of the execution of the said trusts and powers or otherwise in respect of the premises.

(l) Notwithstanding anything in this Indenture contained, the Trustee shall have the right, but shall not be required, to demand, in respect of the authentication of any Bonds, the withdrawal of any cash, the release of any property, or any action whatsoever within the purview of this Indenture, any showings, certificates, opinions, appraisals or other information, or corporate action or evidence thereof, in addition to that by the terms hereof required, as a condition of such action by the Trustee deemed desirable for the purpose of establishing the right of the Authority to the authentication of any Bonds, the withdrawal of any cash, the release of any property or the taking of any other action by the Trustee.

(m) Before taking any action under Section 8.02, 8.03 or 8.04 hereof, the Trustee may require that reasonable indemnity be furnished to it by the owners of the Bonds and for the reimbursement of all expenses which it may incur and to protect it against all liability, except liability which may result from its negligence or willful default, by reason of any action so taken.

(n) The Trustee may deposit the property held in the Funds with a court of general jurisdiction in the city in which the Trustee is located, or the Authority may file an action to interplead the Trust Estate and the Company, the Authority and any other appropriate parties to such action in the event of the Trustee’s resignation hereunder and the failure of a successor trustee to succeed to the duties of the Trustee hereunder within 90 days of the giving of notice of the Trustee’s resignation. Upon the deposit of such property and the filing of a complaint in interpleader, the Trustee shall be relieved of all liabilities and duties under the Loan Agreement and this Indenture. The Authority and the Company shall thereupon submit themselves to the jurisdiction of the District Court.

(o) In the event there occurs a conflict of interest arising as the result of the Trustee’s acting as Trustee or in fiduciary capacity with respect to other Indebtedness of the Company, the Trustee shall appoint a Co-Trustee with respect to the Bonds.

Section 9.03. Resignation or Replacement of Trustee. The Trustee may resign by giving to the Authority, the Company and the Bondholders 90 days’ notice of such resignation, provided, however that no such resignation shall become effective until a successor has been appointed and has accepted the duties of Trustee. The present or any future Trustee may be removed at any time by the Bondholders by an instrument in writing, executed by the Authority and the Company, so long as the Company is not in default or by the owners of a majority in aggregate principal amount of the Bonds then Outstanding; provided, however, that no such removal shall become effective until a successor has been appointed and has accepted the duties of Trustee hereunder.

In case the Trustee shall at any time resign or be removed or otherwise become incapable of acting, subject to the prior written approval of the Authority, a successor may be appointed by the owners of a majority in aggregate principal amount of the Bonds Outstanding by an instrument or concurrent instruments signed by such Bondholders, or their attorneys-in-fact duly appointed; provided that the Authority may appoint a successor until a new successor shall be appointed by the Bondholders as herein authorized. The Authority upon making such appointment shall forthwith give notice thereof to the Bondholders and to the Company, which notice may be given concurrently with the notice of resignation given by any resigning Trustee. Any successor so appointed by the Authority shall immediately and without further act be superseded by a successor appointed in the manner above provided by the owners of a majority in aggregate principal amount of the Bonds Outstanding.

Should any instrument in writing from the Authority be reasonably required by any successor for such vesting and confirming, the Authority shall execute, acknowledge and deliver the said deeds, conveyances and instruments on the request of such successor.

The notices herein provided for, to be given to the Bondholders, shall be given by mailing a copy of such notices by first class mail to the Bondholders at their addresses as the same shall last appear upon the registration books. The notice herein provided for to be given to the Authority, the Company and the retiring Trustee, shall be given in accordance with Section 11.07 hereof.

The instruments evidencing the resignation or removal of the Trustee and the appointment of a successor hereunder, together with all other instruments provided for in this Section, shall be filed and/or recorded by the successor Trustee in each recording office where this Indenture shall have been filed and/or recorded.

Section 9.05. Trustee to Retain Information. So long as any of the Bonds shall be Outstanding, the Trustee shall retain all certificates, financial statements and other written information furnished to it by or on behalf of the Company, the Authority or any other Person under this Indenture, the Loan Agreement and any other agreement or instrument pertaining to the Bonds and shall make such documentation available for review after reasonable notice during regular business hours at the designated corporate trust office of the Trustee to any Bondholder and to any Beneficial Owner. The Trustee shall permit such reviewers to take copies of all or any part of such documentation, subject to their payment of such reasonable copying and handling charges as the Trustee may impose.
