Toward that end, we are writing you to ask for your consent to amend a certain provision of the indenture governing the 9% Convertible Subordinated Debentures due 1999 (the "Securities") of Spartech Corporation. Specifically, the proposed amendment will amend the indenture to allow for $1.5 million of dividends in the aggregate to be paid. The Indenture limits the amount of dividends to "Accumulated Net Earnings" since November 1, 1986. Because of the large losses incurred by the Company during the 1989- 91 period, "Accumulated Net Earnings" since November 1, 1986 equate to a deficit of $6.3 million. However, since 1991 earnings have improved in every quarter and "Accumulated Net Earnings" since November 1, 1991 have amounted to $18.9 million. The purpose, effects and text of the amendment is more fully explained and set forth in the attached Solicitation Statement. Subject to the terms and conditions set forth in the attached Solicitation Statement and the enclosed Consent form, the Company will pay consenting Securities holders $5 in cash for each $1,000 principal amount of Securities for which a consent has been accepted. The Company requests that consents be returned as soon as possible and in any event prior to 12:00 midnight on November 30, 1994. We would appreciate your prompt attention to this matter. Kindest regards, SPARTECH CORPORATION Bradley B. Buechler President and Chief Executive Officer BBB/mlc SPARTECH CORPORATION SOLICITATION OF CONSENT TO AMENDMENT OF A PROVISION OF THE INDENTURE GOVERNING ITS 9% CONVERTIBLE SUBORDINATED DEBENTURES DUE 1999 Spartech Corporation (the "Company" or "Spartech") is soliciting consents of registered holders of its 9% Convertible Subordinated Debentures due 1999 (the "Securities") to amend (the "Proposed Amendment") a provision of the indenture (the "Indenture") governing the Securities. The purpose of the solicitation (the "Solicitation") is to provide management with the ability to pay a dividend on its common shares as early as the first quarter of Fiscal 1995. Specifically, the Proposed Amendment would amend the Indenture to allow for $1.5 million of dividends in the aggregate to be paid irrespective of "Accumulated Net Earnings" defined in the Indenture to be net income of the Company and its consolidated subsidiaries from November 1, 1986 to the end of the most recent fiscal quarter preceding the calculation thereof and determined according to generally accepted accounting principles. This Solicitation Statement was first sent to holders of securities on November 5, 1994. Subject to the terms and conditions set forth in this Solicitation Statement, the Company will (i) accept all properly completed and executed consent forms constituting or deemed to constitute a vote for the Proposed Amendment (the "Consents") received by the Company prior to 12:00 midnight central standard time on November 30, 1994 (as such time which may be extended as provided herein, the "Expiration Date") and not properly revoked only if (x) Consents (the "Requisite Consents") in respect of at least 66 2/3% in aggregate principal amount of Securities that are outstanding and not owned by the Company or any Affiliate (as defined in the Indenture) have been received by the Expiration Date (and not properly revoked) and (y) the supplemental indenture embodying the Proposed Amendment (the "Supplemental Indenture") has been executed and (ii) pay consenting Holders (as hereinafter defined) $5 in cash (the "Consent Payment") for each $1,000 principal amount of Securities for which a Consent has been accepted. The Company will make Consent Payments to consenting Holders as promptly as practicable after the execution of the Supplemental Indenture. Holders who do not deliver their Consents prior to the Expiration Date will not be entitled to receive Consent Payments. The Expiration Date may be extended (including on a daily basis) at any time in the sole discretion of the Company whether or not the Requisite Consents have been received, and the Solicitation may be terminated at any time (including after the Expiration Date) in the sole discretion of the Company whether or not the Requisite Consents have been received. Only those persons ("Registered Holders") in whose name Securities were registered in the register maintained by The Bank of New York, as Trustee (herein so called) and Registrar under the Indenture, as of November 4, 1994 (the "Record Date"), or any other person who has obtained a proxy (in substantially the form included with the Consent form) authorizing such person (or any other person claiming title by or through such person) to vote the applicable Securities on behalf of a Registered Holder, will be eligible to consent to the Proposed Amendment and be entitled to receive a Consent Payment. The Company shall not be deemed to have accepted any Consents until the Supplemental Indenture is executed. If the Company and the Trustee execute the Supplemental Indenture as aforesaid, the Proposed Amendment will be binding upon all holders of Securities, whether or not such Holders have delivered their Consents. Neither this Solicitation nor the giving of Consents is conditioned upon the Company proceeding to pay or declare any dividend on its common stock and shall not obligate the Company to proceed with any such dividend. Consents are being solicited by the Board of Directors of the Company. The transfer of Securities after the Record Date will not have the effect of revoking the election made in any Consent form theretofore validly delivered by a Holder of such Securities, and each Consent will be counted notwithstanding any transfer of the Securities to which such Consent relates, unless the procedure for revoking Consents described herein has been complied with. A Consent received by the Company prior to the Expiration Date in respect of any Securities will be deemed to revoke any Consent form in respect of such Securities having an earlier date that has the "DO NOT CONSENT" or "ABSTAIN" box marked. A Holder who delivers a Consent form with the "DO NOT CONSENT" or "ABSTAIN" box marked will not be entitled to receive a Consent Payment in respect of the Securities to which such Consent form relates unless such Holder delivers a later dated Consent in respect of such Securities prior to the Expiration Date. CONSENTS MAY BE REVOKED IN ACCORDANCE WITH THE PROCEDURE SET FORTH HEREIN AT ANY TIME UP TO, BUT WILL BECOME IRREVOCABLE UPON, THE LATER OF THE EXPIRATION DATE AND THE RECEIPT BY THE TRUSTEE FROM THE COMPANY OF AN OFFICER'S CERTIFICATE IN ACCORDANCE WITH THE INDENTURE CERTIFYING THAT THE REQUISITE CONSENTS HAVE BEEN RECEIVED. ONLY HOLDERS WHO PROPERLY DELIVER THEIR CONSENTS PRIOR TO THE EXPIRATION DATE AND DO NOT PROPERLY REVOKE SUCH CONSENTS WILL BE ENTITLED TO RECEIVE CONSENT PAYMENTS IN THE EVENT THE SUPPLEMENTAL INDENTURE IS EXECUTED. IF ANY HOLDERS SUBMITS AN EXECUTED CONSENT FORM WITHOUT INDICATING A VOTE ON THE PROPOSED AMENDMENT SUCH SUBMISSION WILL BE DEEMED TO CONSTITUTE A VOTE FOR THE PROPOSED AMENDMENT. UNDER NO CIRCUMSTANCES SHOULD ANY PERSON TENDER OR DELIVER SECURITIES. THE SOLICITATION WILL EXPIRE AT 12:00 MIDNIGHT, CENTRAL STANDARD TIME, ON NOVEMBER 30, 1994, UNLESS EXTENDED. -2- AVAILABLE INFORMATION The Company is subject to the informational requirements of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), and, in accordance therewith, is required to file periodic reports and other information with the Securities and Exchange Commission (the "SEC") relating to its businesses, financial statements and other matters.

Capitalized terms used herein and not otherwise defined shall have the meanings ascribed to them elsewhere in this Solicitation Statement. Background and Purpose of the Solicitation A principal objective of management is to enhance shareholder value through current income and capital appreciation. Toward that end, the Board of Directors have considered and are studying the possibility of paying a dividend on the Common Shares of the Company. Although no dividend has been declared, provisions of the Indenture restrict paying a dividend. The Indenture limits the amount of dividends to "Accumulated Net Earnings" since November 1, 1986. Because of the large losses incurred by the Company during the 1989-91 period, "Accumulated Net Earnings" since November 1, 1986 equate to a deficit of $6.3 million. However, since 1991 earnings have improved in every quarter and "Accumulated Net Earnings" since November 1, 1991 have amounted to $18.9 million. Management estimates the earliest a dividend could be paid under the existing Indenture would be the second or third quarter of Fiscal 1995. Accumulated Net Earnings of the Company throughout the quarter ended July 30, 1994, was a loss of $6.3 Million calculated as follows: (Dollars in Thousands) Fiscal Year Ending Net Earnings (Loss) 1987 $ 2,478 1988 3,832 1989 (12,713) 1990 (1,109) 1991 (17,714) 1992 4,220 1993 6,716 Nine Months Ending 7/30/94 7,974 Estimated Cumulative Amounts Through 7/30/94 $ (6,316) Management believes the Proposed Amendment is in the best interest of the Company which would allow the Company to consider a dividend as early as the first quarter of Fiscal 1995. The Company is unable to predict the effect, if any, that the Proposed Amendment would have on the market price of the Securities. Proposed Amendment The Indenture will be amended to provide that dividends up to $1.5 million may be paid irrespective of Accumulated Net Earnings. -4- The Solicitation The Consent Payments......... The Company will pay $5 in cash for each $1,000 principal amount of Securities for which a Consent is received and accepted. The Company will make the Consent Payments as promptly as practicable after the execution of the Supplemental Indenture. The Consent Payment to each consenting Holder will be made by check sent by first class mail. Expiration Date.............. The Expiration Date is 12:00 midnight, Central Standard time, on November 30, 1994, unless the Solicitation is extended, in which case the term "Expiration Date" means the later date and time to which the solicita- tion is extended. The Company may extend the Solicitation at any time (including on a daily basis). Conditions to Proposed Amendment.................... The effectiveness of the Proposed Amendment is conditioned upon receipt of valid Consents (not properly revoked) from Holders of 66 2/3% in aggregate principal amount of Securities outstanding (other than those held by the Company or any Affiliate) and acceptance of such Consents by the Company. The Company will not be deemed to accept any Consents until the Supplemental Indenture is executed. Holders...................... The term "Registered Holder," when used with respect to the Solicitation, means any person in whose name a Security was registered in the register maintained by the Trustee as of the Record Date, and the term "Holder" means any Registered Holder or any other person who has obtained a proxy (in substantially the form included with the Consent form) authorizing such person (or any other person claiming title by or through such person) to vote Securities on behalf of a Registered Holder. Procedure of Consenting...... A beneficial owner or registered holder of Securities desiring to deliver a Consent form should either (i) if such beneficial owner or registered -5- holder is a Holder of such Securities, complete and sign the Consent form, or a facsimile thereof, have the signature thereon (and on any proxy delivered therewith) guaranteed or notarized (unless such Consent form or proxy, as the case may be, is given by or for the account of an Eligible Institution) and mail or otherwise deliver the Consent form, or such facsimile (together with a duly executed proxy in substantially the form included with the Consent form, if the Holder was not a Registered Holder, and any other proxy in substantially the form included with the Consent form, guarantee or notarization required to establish a beneficial owner's or registered holder's right to execute a Consent form) to the Information Company at its address set forth below or (ii) if such beneficial owner or registered holder is not a Holder of such Securities, request the Registered Holder of such Securities effect the transaction for such beneficial owner or registered holder or to provide such beneficial owner or registered holder with a proxy (in substantially the form included with the Consent form) authorizing such beneficial owner or registered holder to vote such Securities on behalf of such Registered Holder. The term Eligible Institution," when used with respect to the Solicitation, means a firm that is a member of a registered national securities exchange or the National Association of Securities Dealers, Inc., or a commercial bank or trust company having an office or correspondent in the United States. If any Holder submits an executed Consent form without indicating a vote on the Proposed Amendment such submission will be deemed to constitute a vote for the Proposed Amendment. Revocation................... Consents may be revoked by filing a written notice of revocation with the Trustee at any time prior to the later of the Expiration Date and receipt by the Trustee from the -6- Company of an officer's certificate in accordance with the Indenture certifying as to receipt of the Requisite Consents. Any Holder who properly revokes a Consent will not receive Consent Payments, unless such Consent is properly redelivered prior to the Expiration Date. The transfer of Securities after the Record Date will not have the effect of revoking the election made in any Consent form theretofore validly delivered by a Holder of such Securities, and each Consent will be counted notwith- standing any transfer of the Securities to which such Consent relates unless the procedure for revoking Consents described herein has been complied with. A Consent received by the Company prior to the Expiration Date in respect of any Securities will be deemed to revoke any Consent form in respect of such Securities having an earlier date that has the "DO NOT CONSENT" or "ABSTAIN" box marked. A Holder who delivers a Consent form with the "DO NOT CONSENT" or "ABSTAIN" box marked will not be entitled to receive a Consent Payment in respect of the Securities to which such Consent form relates unless such Holder delivers a later dated Consent in respect of such Securities prior to the Expiration Date. Delivery of Consent Forms.... Each Consent form should be sent to the Company, as follows: Spartech Corporation 7733 Forsyth Boulevard, Suite 1450 Clayton, MO 63105 Telephone Number: (314) 721-4242 Facsimile Number: (314) 721-1447 Certain Tax Considerations... In the opinion of Management, the only Federal income tax consequence of adoption of the Proposed Amendment to Holders of Securities will be that the full amount of the Consent Payment would be subject to tax as ordinary income to those holders who receive it. See "Certain Federal Income Tax Consequences." -7- Assistance; Additional Materials.................. Questions regarding the Solicitation relating to the procedure for consenting as well as requests for assistance for additional material should be directed to Mr. David B. Mueller at the Company as indicated above. -8- BACKGROUND AND PURPOSE OF THE SOLICITATION A principal objective of Management is to enhance shareholder value through capital appreciation and current income. Toward that end, the Board of Directors has considered and is studying the possibility of paying a dividend on the Common Shares of the Company. Although no dividend has been declared, the provisions of the Indenture restrict paying a dividend unless the Company has Accumulated Net Earnings since November 1, 1986. Through the Company's quarter ended July 30, 1994, Accumulated Net Earnings were a deficit of $6.3 Million. The Company has had positive net income for each of the last two fiscal years and for the first nine months of its current fiscal year. (See summary on Page 4). Management estimates the earliest a dividend could be paid under the existing Indenture would be the second or third quarter of Fiscal 1995. Management believes the Proposed Amendment is in the best interest of the Company because the Proposed Amendment will allow the Company to consider a dividend as early as the first quarter of Fiscal 1995. Based on the foregoing factors, management urges the holders of Securities to give their consent. PROPOSED AMENDMENT Set forth below is a description of the proposed modification to the Indenture for which the Consents of the Registered Holders of the Securities are being solicited hereby. This description is qualified by reference to the full provisions of the existing Indenture and the proposed Supplemental Indenture set forth in Annex A hereto. The capitalized terms used herein and not otherwise defined in this Solicitation Statement shall have the meanings ascribed to them in the Indenture or the Supplemental Indenture as set forth in Annex A hereto. Each holder of Securities, by executing and delivering a Consent, will consent to the Proposed Amendment as set forth in Annex A hereto and described below. Proposed Amendment If the Requisite Consents are received, the Indenture may be amended as follows: i) To provide that Section 1007 of the Indenture entitled LIMITATIONS OF DIVIDENDS AND OTHER STOCK PAYMENTS be modified to allow up to $1.5 million of dividend payments to be paid irrespective of the amount of Accumulated Net Earnings since November 1, 1986. -9- Effects of Proposed Amendment The principal effect of the Proposed Amendment will be to allow a dividend of up to $1.5 million to be paid irrespective of the "Accumulated Net Earnings" since November 1, 1986. As of July 31, 1994, the Company would have needed to earn an additional $6.3 million of Consolidated Net Income in order to eliminate the deficit in its dividend capacity. By comparison, under the Proposed Amendment, the Company would need to earn no additional Consolidated Net Income in order to pay a dividend of up to $1.5 million. -10- THE SOLICITATION Terms of the Solicitation Subject to the terms and conditions set forth herein, the Company hereby offers to make a Consent Payment of $5 for each $1,000 principal amount of Securities for which a valid Consent is (i) received by the Company at the address set forth below prior to the Expiration Date, (ii) not properly revoked as provided herein prior to the later of the Expiration Date and receipt by the Trustee from the Company of an officer's certificate in accordance with the Indenture certifying to the receipt of the Requisite Consents and (iii) accepted by the Company as provided herein. CONSENT PAYMENTS WILL BE MADE ONLY TO HOLDERS WHO, PRIOR TO THE EXPIRATION DATE, HAVE VALIDLY CONSENTED TO THE PROPOSED AMENDMENT. ANY BENEFICIAL OWNER OR REGISTERED HOLDER OF SECURITIES WHO IS NOT THE REGISTERED HOLDER AS OF THE RECORD DATE BUT WHO DESIRES TO GIVE A CONSENT AND THUS BE ENTITLED TO RECEIVE A CONSENT PAYMENT IN THE EVENT THE SUPPLEMENTAL INDENTURE IS EXECUTED MUST OBTAIN A PROXY (IN SUBSTANTIALLY THE FORM INCLUDED WITH THE CONSENT FORM) FROM THE REGISTERED HOLDER OF SUCH SECURITIES AS OF THE RECORD DATE THAT AUTHORIZES SUCH BENEFICIAL OWNER OR REGISTERED HOLDER TO VOTE THE SECURITIES ON BEHALF OF SUCH REGISTERED HOLDER AS OF THE RECORD DATE IN THE MANNER DESCRIBED BELOW. The Company will make the Consent Payments as promptly as practicable after the execution of the Supplemental Indenture. Such payments will be made to consenting Holders by check sent by first class mail. The Company reserves the right, in its sole discretion, to delay making Consent Payments, in whole or in part, in order to comply with any applicable law. The Consents will become irrevocable on the later of the Expiration Date and the date on which the Trustee receives from the Company an officer's certificate in accordance with the Indenture certifying that the Requisite Consents have been received. Following such delivery, the Trustee and the Company may execute the Supplemental Indenture. The Proposed Amendment shall be effective upon execution of the Supplemental Indenture. After execution of the Supplemental Indenture, all holders of Securities, including non-consenting holders and all subsequent holders of the Securities, will be bound by the Proposed Amendment. Non-consenting holders will not be entitled to any rights of appraisal or similar rights of dissenters with respect to the proposed modification to the Indenture. The term "Expiration Date" means 12:00 midnight, Central Standard time, on November 30, 1994, unless the Company, in its sole discretion, extends the period during which the Solicitation is open, in which event the term "Expiration Date" shall mean the time and date on which the Solicitation, as so extended by the Company, expires. The Company reserves the right to extend the Solicitation at any time and from time to time (including on a daily basis) by giving oral or written notice to the Trustee no later than 9:00 a.m., Central Standard time, on the business day following any previously announced Expiration Date. Any such extension will be followed -11- as promptly as practicable by public announcement (or written notice to the Registered Holders of Securities) thereof. The Company will not be obligated, and does not intend, to extend the Solicitation if the Requisite Consents have been received as of the Expiration Date. The Company expressly reserves the right (i) to terminate the Solicitation at any time (including after the Expiration Date) prior to the execution of the Supplemental Indenture (whether or not the Requisite Consents have been received) by giving oral or written notice of such termination to the Trustee, (ii) not to extend the Solicitation beyond the Expiration Date and (iii) to amend, at any time or from time to time, the terms of Solicitation. Any such termination or amendment will be followed as promptly as practicable by public announcement or written notice to the Registered Holders of Securities thereof. Subject to the foregoing, if Consents received by the Company (and not properly revoked) as of the Expiration Date are sufficient to permit adoption of the Proposed Amendment, the Company intends to execute the Supplemental Indenture. Consents will be deemed to be accepted when the Supplemental Indenture has been executed by the Company and the Trustee. The Company reserves the right to accept any or all Consents received after the Expiration Date. Consent Procedures This Solicitation Statement is being sent to all Registered Holders. The Company has designated November 4, 1994, as the Record Date for the Solicitation. Approval of the Proposed Amendment requires the consent of the Registered Holders of at least 66 2/3% in aggregate principal amount of the Securities that are outstanding and not owned by the Company or any Affiliates. As of the date of this Solicitation Statement, $10,134,000 principal amount of Securities were outstanding, none of which were owned by the Company or any Affiliate. Only (i) Registered Holders or (ii) any other person who has obtained a proxy (in substantially the form included with the Consent form) which authorizes such person (or any other person claiming title by or through such person) to vote the applicable Securities on behalf of such Registered Holder (collectively, "Holders") may execute and deliver a Consent and receive a Consent Payment. A beneficial owner of Securities who is not the Registered Holder of such Securities (e.g., a beneficial holder whose Securities are registered in the name of a nominee such as a brokerage firm) and a person who becomes a registered holder with respect to Securities after the Record Date must (i) arrange with the Registered Holder to execute and deliver a Consent on such beneficial owner's or registered holder's behalf or (ii) obtain a proxy (in substantially the form included with the Consent form) from the Registered Holder authorizing the beneficial owner or registered holder to vote the Securities on behalf of such Registered Holder. A Consent by a Holder is a continuing Consent notwithstanding that registered ownership of the Securities has been transferred subsequent to the Record Date unless the prior Consent is timely revoked by a Holder of such Securities in accordance with the procedure described herein. -12- A Consent received by the Company prior to the Expiration Date in respect of any Securities will be deemed to revoke any Consent form in respect of such Securities having an earlier date that has the "DO NOT CONSENT" or "ABSTAIN" box marked. A Holder who delivers a Consent form with the "DO NOT CONSENT" or "ABSTAIN" box marked will not be entitled to receive a Consent Payment in respect of the Securities to which such Consent form relates unless such Holder delivers a later dated Consent in respect of such Securities prior to the Expiration Date. The Consent form is enclosed with this Solicitation Statement. A Consent form (or, if the Holder signing such Consent form is not the Registered Holder, the accompanying irrevocable proxy in substantially the form included with the Consent form), to be effective, must be executed by the Registered Holder of the Securities to which such Consent form (or such irrevocable proxy) relates in the same manner as the name of the Registered Holder appears on such Securities. If such Securities are held of record as of the Record Date by two or more Registered Holders, all such Registered Holders must sign the Consent form (or such irrevocable proxy). If such Securities are registered in different names as of the Record Date, separate Consent forms (or irrevocable proxies) must be executed covering each form of registration. If a Consent form is signed by a trustee, executor, administrator, guardian, attorney-in-fact, officer of a corporation, or other person acting in a fiduciary or representative capacity, such person must so indicate when signing and must submit with the Consent form appropriate evidence of authority to execute the Consent form. In addition, (i) if a Holder is a Registered Holder and a Consent form relates to less than the total principal amount of Securities registered in the name of such Registered Holder as of the Record Date or (ii) if a Holder is not a Registered Holder and is consenting pursuant to a proxy given by a Registered Holder and a Consent form relates to less than the total principal amount of Securities to which such proxy relates, such Consent form must list the certificate numbers and principal amount of Securities to which the Consent form relates. Otherwise, the Consent form will be deemed to relate to the total principal amount of Securities registered in the name of such Registered Holder or to which such proxy relates, as the case may be. The ownership of Securities shall be proven by the Trustee, as registrar of the Securities. All questions as to the validity, form, eligibility (including time and receipt) and the acceptance of Consent forms and revocations of elections made on Consent forms with respect to Securities will be resolved in the first instance by the Company, whose determination shall be binding subject only to such final review as may be prescribed by the Trustee in accordance with the Indenture concerning proof of execution and ownership. The Company reserves the absolute right to reject any or all Consent forms and revocations that are not in proper form or the acceptance of which could, in the opinion of the Company's counsel, be unlawful. The Company also reserves the right, subject to such final review as the Trustee may prescribe in accordance with the Indenture for proof of execution and ownership, to waive any irregularities or conditions of delivery as to particular Consent forms or revocations. Unless waived, any irregularities in connection with the deliveries must be cured within such time as the Company determines. Neither the Company, the Trustee, or any other person shall be under any duty to give notification of any such irregularities or waiver, nor shall any of them incur any liability for -13- failure to give such notification. Deliveries of such Consent forms or notices of revocation will not be deemed to have been made until such irregularities have been cured or waived. The Company's interpretation of the terms and conditions of this Solicitation shall be binding. Consents to the Proposed Amendment, to be effective, must be properly executed and received by the Company prior to the Expiration Date. Each Holder of Securities wishing to vote Securities in respect of the Proposed Amendment must complete, sign and date the accompanying Consent form (or a facsimile thereof) in accordance with the instructions set forth herein and therein have the signatures thereon (and on any proxy delivered therewith) notarized or guaranteed and mail, hand deliver or send by overnight courier, or telecopy the Consent form and any other required documents to the Company. The method of delivery of all documents, including fully executed Consent forms, is at the election and risk of the Holder. Such delivery will be deemed made only when actually received by the Company. A signature guarantee must be by a firm that is a member of a registered national securities exchange or a member of the National Association of Securities Dealers, Inc., or by a commercial bank or trust company having an office or correspondent in the United States. IF ANY HOLDER SUBMITS AN EXECUTED CONSENT FORM WITHOUT INDICATING A VOTE ON THE PROPOSED AMENDMENT SUCH SUBMISSION WILL BE DEEMED TO CONSTITUTE A VOTE FOR THE PROPOSED AMENDMENT. Each Consent form should be sent to the Company, as follows: Spartech Corporation 7733 Forsyth Boulevard, Suite 1450 Clayton, MO 63105 Telephone Number: (314) 721-4242 Facsimile Number: (314) 721-1447 HOLDERS OF SECURITIES WHO WISH TO CONSENT SHOULD MAIL, HAND DELIVER, SEND BY OVERNIGHT COURIER, OR TELECOPY THEIR PROPERLY COMPLETED AND EXECUTED CONSENT FORMS TOGETHER WITH OTHER REQUIRED DOCUMENTS TO THE COMPANY IN ACCORDANCE WITH THE INSTRUCTIONS SET FORTH HEREIN AND THEREIN. CONSENT FORMS SHOULD BE DELIVERED TO THE COMPANY. IN NO EVENT SHOULD A HOLDER TENDER OR DELIVER SECURITIES. -14- Conditions of the Solicitation The Company shall not be deemed to have accepted any Consents unless and until the Supplemental Indenture is executed by the Company and the Trustee. Revocation of Consents Any Holder of Securities as to which a Consent has been given may revoke such Consent as to such Securities or any portion of such Securities (in integral multiples of $1,000) by filing a written notice of revocation with the Trustee at the Bank of New York, 48 Wall Street, New York, NY 10005, Attn: Alfia Monastra, prior to the later of the Expiration Date and the time that the Trustee receives from the Company an officer's certificate in accordance with the Indenture certifying to receipt of the Requisite Consents. The transfer of Securities after the Record Date will not have the effect of revoking the election made in any Consent form theretofore validly given by a Holder of such Securities, and each Consent will be counted notwithstanding any transfer of the Securities to which Consent relates, unless the procedure for revoking Consents described below has been complied with. A Consent received by the Company prior to the Expiration Date in respect of any Securities will be deemed to revoke any Consent form in respect of such Securities having an earlier date that has the "DO NOT CONSENT" or "ABSTAIN" box marked. A Holder who delivers a Consent form with the "DO NOT CONSENT" or "ABSTAIN" box marked will not be entitled to receive a Consent Payment in respect of the Securities to which such Consent form relates unless such Holder delivers a later dated Consent in respect of such Securities prior to the Expiration Date. A written notice of revocation, to be effective, must (i) contain the name of the Registered Holder, the certificate numbers to which such revocation relates, the principal amount of Securities to which such revocation relates and the signature of a Holder (with such signature, and the signatures in any accompanying proxy, notarized or guaranteed as described above) and (ii) be accompanied by the properly completed irrevocable proxy (in substantially the form included with the Consent form) if such Holder is not the Registered Holder of such Securities. The revocation (or, if the Holder is not the Registered Holder, the accompanying irrevocable proxy), to be effective, must be executed by the Registered Holder of such Securities in the same manner as the name of the Registered Holder appears on the Securities to which the revocation relates. If a revocation is signed by a trustee, executor, administrator, guardian, attorney-in-fact, officer of a corporation, or other person acting in a fiduciary or representative capacity, such person must so indicate when signing and must submit with the revocation appropriate evidence of authority to execute the revocation. A revocation of the Consent shall be effective only as to the Securities listed on the revocation and only if such revocation complies with the provisions of this Solicitation Statement. Only a Holder of Securities is entitled to revoke a Consent previously given. A beneficial owner of Securities or a registered holder of Securities other than the Registered Holder must arrange with the Registered Holder to execute and deliver on his behalf a revocation of any Consent already given with respect to such Securities, or obtain an irrevocable proxy (in substantially the form included with the Consent form) form the Registered Holder authorizing such beneficial holder or registered holder to -15- revoke such Consent in accordance with the procedures described herein. A purported notice of revocation that is not received by the Trustee in a timely fashion and accepted by the Trustee as a valid revocation will not be effective to revoke a Consent previously given. A revocation of a Consent may only be rescinded by the execution and delivery of a new Consent. A Holder who has delivered a revocation may thereafter deliver a new Consent by following one of the described procedures at any time prior to the Expiration Date. Prior to the execution of a Supplemental Indenture, the Company intends to consult with the Trustee to determine whether such Trustee has received any revocations of Consents. The Company reserves the right to contest the validity of any such revocations. Assistance; Additional Materials Questions relating to the procedure for consenting or the solicitation as well as requests for assistance or for additional copies of this Solicitation Statement or the Consent form may be directed to the Company at the address set forth above. -16- CERTAIN FEDERAL INCOME TAX CONSEQUENCES The following is a general discussion of certain of the anticipated Federal income tax consequences of the Proposed Amendment and the Consent Payment. This summary is based upon the relevant provisions of the Internal Revenue Code of 1986, as amended, and related regulations, revenue rulings and decisions now in effect, all of which are subject to change. The summary does not attempt to address the Federal income tax consequences of all categories of holders of Securities, some of which may be subject to special rules (e.g., life insurance companies, tax-exempt entities and foreign taxpayers). All holders of Securities are urged to consult their own tax advisers in determining the Federal, state, local and any other tax consequences of the Proposed Amendment and the Consent Payment. The Proposed Amendment and the Consent Payment Management believes that the only Federal income tax consequence of adoption of the Proposed Amendment to holders of Securities will be that the full amount of the Consent Payment will be subject to tax as ordinary income to those holders who receive it. This conclusion is based upon the Management's belief that such adoption will not be treated as a constructive exchange of the Securities for new securities. No ruling on the constructive exchange issue has been or will be sought from the Internal Revenue Service. Backup Withholding Under the Federal income tax law, a holder of Securities may, under certain circumstances, be subject to backup withholding at the rate of 31% with respect to the Consent Payment, unless such holder (i) is a corporation or is otherwise exempt and, when required, demonstrates this fact or (ii) provides a correct taxpayer identification number, certifies as to no loss of exemption from backup withholding and otherwise complies with applicable requirements of the backup withholding rules. See the instructions with respect to backup withholding contained in the accompanying Consent form. Other Tax Considerations There may be other Federal, state, local or foreign tax considerations applicable to the circumstances of a holder of a Security. Accordingly, all holders of Securities should consult their own tax advisers as to particular tax consequences to them of the Proposed Amendment and the Consent Payment. THE PRECEDING DISCUSSION OF CERTAIN FEDERAL INCOME TAX CONSEQUENCES IS INTENDED FOR GENERAL INFORMATION ONLY, AND DOES NOT CONSTITUTE TAX ADVICE. EACH HOLDER OF A SECURITY SHOULD CONSULT HIS OR HER OWN TAX ADVISER AS TO THE FEDERAL, STATE, LOCAL AND FOREIGN TAX CONSEQUENCES TO HIM OR HER OF THIS CONSENT SOLICITATION. -17- PRINCIPAL HOLDERS AND SECURITY OWNERSHIP OF MANAGEMENT The following table sets forth the names and addresses of those persons who are known by the Company to be the record owners of more than 5% in principal amount of the Securities outstanding as of the Record Date, based on information supplied to the Company by the Trustee, and as to each, the principal amount and the percentage of the total Securities which are owned by such person. Such information represents the record ownership of Securities, since the Company lacks sufficient information to determine whether, or by whom, such Securities are owned beneficially. The Company does not presently know whether or not such principal holders will consent to the Proposed Amendment. Mr. David B. Mueller, an officer and director, directly or beneficially owns $107,000 of face amount of the securities. No other directors or officers own directly or indirectly any of the Securities. Principal Amount Percentage Name and Address of Held of Record as of Securities Registered Holder of the Record Date Outstanding -18- EXPENSES OF SOLICITATION The Company will bear the costs of the Solicitation. The Company will reimburse the Trustee for expenses that the Trustee incurs in connection with the Solicitation. The Company will also reimburse banks, trust companies, securities dealers, nominees, custodians and fiduciaries for their reasonable expenses in forwarding Consent forms and other materials to beneficial owners of Securities. In addition to the solicitation of consents by mail, employees of the Company may solicit consents by personal interviews, by telephone or by telegraph. Employees of the Company will not be specially compensated for soliciting consents. If such personal interviews or telephone conversations are used to solicit consents, this Solicitation Statement and the appropriate Consent forms will precede the interview or telephone conversation. If as a result of the interview or conversation additional Consent forms are required, they will be forwarded to the registered holder. INCORPORATION OF CERTAIN DOCUMENTS BY REFERENCE The Company's Annual Report on Form 10-K for the fiscal year ended October 30, 1993, and the Company's Quarterly Report on Form 10-Q for the 39 weeks ended July 30, 1994, each of which has been filed by the Company with the Securities and Exchange Commission pursuant to the Securities Exchange Act of 1934, are attached to this Solicitation Statement and are hereby incorporated herein by reference. -19- ANNEX A SPARTECH CORPORATION 9% Convertible Subordinated Debentures due 1999 ____________________ FIRST SUPPLEMENTAL INDENTURE Dated as of [ ], 1994 Supplementing the Indenture dated as of April 15, 1987 ____________________ BANK OF NEW YORK (as successor to CHEMICAL BANK) Trustee FIRST SUPPLEMENTAL INDENTURE dated as of [ ], 1994, between SPARTECH CORPORATION, a Delaware corporation (the "Company"), and BANK OF NEW YORK, a national banking association (the "Trustee").

IMPORTANT TAX INFORMATION THE FEDERAL INCOME TAX DISCUSSION SET FORTH BELOW IS INCLUDED FOR GENERAL INFORMATION ONLY. EACH HOLDER IS URGED TO CONSULT A TAX ADVISOR TO DETERMINE THE PARTICULAR TAX CONSEQUENCES TO SUCH HOLDER (INCLUDING THE APPLICABILITY AND EFFECT OF STATE, LOCAL AND OTHER TAX LAWS) OF THE CONSENTS PURSUANT TO THE SOLICITATION, CERTAIN HOLDERS (INCLUDING INSURANCE COMPANIES, TAX-EXEMPT ORGANIZATIONS, FINANCIAL INSTITUTIONS, DEALERS IN SECURITIES AND FOREIGN PERSONS OR ENTITIES) MAY BE SUBJECT TO SPECIAL RULES NOT DISCUSSED BELOW. THE DISCUSSION DOES NOT CONSIDER THE EFFECT OF ANY APPLICABLE FOREIGN, STATE, LOCAL OR OTHER TAX LAWS. Substitute Form W-9 Under the Federal income tax laws, the Paying Agent may be required to withhold 31% of the amount of any payment made to certain Holders pursuant to the Solicitation. In order to avoid such backup withholding, each Holder must provide the Information Agent with such Holder's correct taxpayer identification number ("TIN") by completing the Substitute Form W-9 set forth below. In general, if a Holder is an individual, the TIN is the Social Security number of such individual. If the Depositary is not provided with the correct TIN, the Holder may be subject to a $50 penalty imposed by the Internal Revenue Service. Certain Holders (including, among others, all corporations) are not subject to these backup withholding and reporting requirements. These Holders should enter the correct TIN in Part 1 of the Substitute Form W-9, write "Exempt" in Part 2 of the Substitute Form W-9, sign under the certification and date the form. For further information regarding backup withholding and instructions for completing the Substitute Form W-9 (including how to obtain a TIN if you do not have one and how to complete the Substitute Form W-9 if Securities are held in more than one name), consult the Guidelines for Certification of Taxpayer Identification Number. Consequences of Failure to File Substitute Form W-9 Failure to complete Substitute Form W-9 may require the Paying Agent to withhold 31% of the amount of any payments made pursuant to the Solicita- tion. Backup withholding is not an additional Federal income tax. Rather, the Federal income tax liability of a person subject to backup withholding will be reduced by the amount of tax withheld. If withholding results in an overpayment of taxes, the Holder may claim a refund from the Internal Revenue Service.
