     The City of Springdale, Arkansas, a public body politic and corporate, organized and existing under the laws of the State of Arkansas (the “City”), 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 February 1, 2008 (the “Indenture”), between the City 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 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 City designated as “City of Springdale, Arkansas Industrial Development Refunding Revenue Bonds (Advanced Environmental Recycling Technologies, Inc Project) Series 2008” (the “Bonds”). The Bonds have been issued under Title 14, Chapter 267 of the Arkansas Code of 1987, Annotated, and Title 14, Chapter 164, Subchapter 2 of the Arkansas Code of 1987, Annotated (the “Act”), to refinance costs of acquiring, constructing and equipping certain solid waste recovery and manufacturing facilities (the “Facilities”) and to fund a reserve fund with respect to the Series 2008 Bonds.

     This Bond is a limited obligation of the City payable solely from and secured by (a) a pledge of certain rights of the City under and pursuant to the Loan Agreement dated as of February 1, 2008 (the “Loan Agreement”), between the City 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 Arkansas or any county, city, town, school district, or other subdivision of the State of Arkansas or of any other political subdivision or body corporate and politic within the State of Arkansas other than the City (but only to the extent of the revenues pledged in this Indenture), and neither the State of Arkansas, nor any county, town, school district or other subdivision of the State of Arkansas, except the City to the extent provided above, shall be liable hereon; nor shall this Bond constitute the giving, pledging, or loaning of the faith and credit of the State of Arkansas, or any county, city, town, school district or other subdivision of the State of Arkansas or of any other political subdivision or body corporate and politic within the State of Arkansas, but shall be payable solely from the funds pledged therefor. The issuance of this Bond shall not, directly or indirectly or contingently, obligate the State of Arkansas or any subdivision of the State of Arkansas nor empower the City 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 Bonds and the interest thereon do not constitute an indebtedness of the City within the meaning of any constitutional or statutory limitation.

     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 City, 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 City and the Trustee.

     The Bonds are subject to optional redemption by the City 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 Springdale, Arkansas. The Bonds are also subject to optional redemption by the City 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 City. 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 City may attempt to have established a securities depository/book-entry system relationship with another qualified Depository under this Indenture. If the City does not or is unable to do so, the City 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 City 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 CITY, 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 City 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 City 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 City and of the owners of the Bonds may be made with the consent of the City 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 City Council of the City 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 Arkansas 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, the City of Springdale, Arkansas has caused this Bond to be signed in its name and on its behalf by the manual or facsimile signature of its Mayor, and a facsimile of its corporate seal to be affixed hereon and attested by the manual or facsimile signature of its City Clerk.
