                                       TO
                            NONQUALIFIED STOCK OPTION


   1. Term and Termination of the Option.  The Option is effective as of the
Option Date. The Option will expire, terminating the Optionee's right to
exercise it, automatically and without any requirement of notice to the
Optionee, on the "Expiration Date" specified above; except that:
   (i)   If the Optionee terminates his or her Employment prior to the
      Expiration Date for any reason except Disability or Retirement, the
      Option will expire immediately upon the termination of the Optionee's
      employment; or
   (ii)  If Spartech terminates the Optionee's Employment prior to the
      Expiration Date for Cause, the Option will expire immediately upon the
      termination of the Optionee's employment; or
   (iii) If Spartech terminates the Optionee's Employment for any other

      year after the date of death, but in no event later than the Expiration
      Date; or

      Employment provided in Section 1(iii), the Option will expire upon
      written notice of termination given by Spartech to the Optionee, but in
      no event later than the Expiration Date.
   2. When the Option Becomes Exercisable.  The Option will become exercisable
("vest") in installments at a rate of 25% of the total number of Option Shares

basis; provided, however, that, subject to the above termination provisions:
   (i)   The Option will immediately vest in full (A) upon the death of the
      Optionee, or (B) if the Optionee's Employment terminates because of
      Disability, or (C) in the event of a Change in Control;
   (ii)  The Option will continue to vest in accordance with the above
      schedule if the Optionee's Employment terminates by reason of the
      Optionee's Retirement; and
   (iii) Except as set forth above, no part of the Option will vest after the
      termination of the Optionee's Employment.
   3. Exercise of the Option.  Subject to the other terms and conditions
contained herein, the Option may be exercised only in the following manner:
   (a)   Who May Exercise the Option.  The Option may be exercised during the
lifetime of the Optionee only by the Optionee or a permitted transferee of the
Option registered as such on Spartech's books, and thereafter only by the
personal representative of the Optionee or such permitted transferee or a person
who acquired the right to exercise the Option by bequest or inheritance or by
reason of the death of the Optionee or such permitted transferee.  Solely for
purposes of Sections 3(b) and 3(c), the term "Optionee" shall include any person
permitted to exercise the Option.
   (b)   Method of Exercise.  The Optionee shall deliver to Spartech's Chief
Financial Officer or Director of Taxes or other representative designated or
authorized by Spartech for such purpose, at Spartech's principal office, a
written notice signed by the Optionee (the form of which may be prescribed by
Spartech) specifying the number of Option Shares which the Optionee wishes to
purchase pursuant to the Option and the method of payment, accompanied by:
   (i)   Payment of the Exercise Price as described in Section 3(c); plus
   (ii)  Payment of any required withholding taxes as described in Section
      3(d); plus
   (iii) Certificates for any shares surrendered in payment of the option
      price, or such other evidence of ownership and transfer of such shares
      as Spartech may require.
   (c)   Payment of Exercise Price.  The Optionee may pay the Exercise Price by
any one or a combination of the following methods:
   (i)   By delivering a certified or cashier's check in the amount of the
      Exercise Price; or
   (ii)  By delivering shares of Spartech common stock owned by the Optionee
      for at least six months preceding the exercise date and having a fair
      market value equal to the Exercise Price; or
   (iii) In lieu of such delivery, by attesting (in such form as Spartech may
      require) to the Optionee's ownership of deliverable shares of Spartech
      common stock owned by the Optionee for at least six months preceding
      the exercise date and having a fair market value equal to the Exercise
      Price, in which event the number of such shares shall be withheld from
      the Option Shares issued pursuant to the exercise; provided that such
      shares may not have been attested to for any similar purpose within the
      previous six months; or
   (iv)  If Spartech consents in advance, by authorizing a third party to
      sell a portion of the acquired Option Shares promptly on the open
      market and remit the sale proceeds to Spartech not later than the
      settlement date in payment of the Exercise Price.
   (d)   Payment of Withholding Taxes.  As a condition of the exercise of the
Option, at or before the time of exercise the original Optionee shall pay, or
make arrangements satisfactory to Spartech to assure the timely payment of, all
federal and state taxes required to be withheld by Spartech as a result of the
exercise.  Such withholding taxes may be paid by any one or a combination of the
following methods:
   (i)   By delivering a certified or cashier's check in the amount of such
      taxes; or
   (ii)  By delivering shares of Spartech common stock owned by the Optionee
      for at least six months preceding the exercise date and having a fair
      market value equal to the amount of such taxes; or
   (iii) In lieu of such delivery, by attesting (in such form as Spartech may
      require) to the Optionee's ownership of deliverable shares of Spartech
      common stock owned by the Optionee for at least six months preceding
      the exercise date and having a fair market value equal to the amount of
      such taxes, in which event the number of such shares shall be withheld
      from the Option Shares issued pursuant to the exercise; provided that
      such shares may not have been attested to for any similar purpose
      within the previous six months; or
   (iv)  If Spartech consents in advance, by authorizing a third party to
      sell a portion of the acquired Option Shares promptly on the open
      market and remit the sale proceeds to Spartech not later than the
      settlement date in payment of such taxes; or
   (v)   By the partial surrender and cancellation of the Option as to an
      aggregate number of shares of Spartech common stock which, if issued,
      would have a fair market value equal to the amount of such taxes;
      provided that no taxes in excess of the minimum amount of taxes
      required to be withheld by applicable laws or regulations may be paid
      by this method.
If for any reason payment is not made as aforesaid, Spartech may withhold the
amount of any remaining withholding taxes from any other compensation due to the
Optionee.
   (e)   Fair Market Value.  For the purposes of Sections 3(c) and 3(d), the
"fair market value" of Spartech common stock means the closing price (i.e.
excluding after-hours trading) on the New York Stock Exchange (or such other
exchange as may then be the principal exchange for Spartech common stock) on the
last day on which Spartech common stock was traded prior to the date the notice
of exercise is received by Spartech.
   (f)   Option Shares Not Issued Until Full Payment Received.  The Option
Shares shall not be deemed issued for any purpose except to permit a sale
pursuant to Section 3(c)(iv) or 3(d)(iv), and certificates for the Option Shares
shall not be delivered to the Optionee, until full payment has been received by
Spartech; and the Optionee shall not have any right or status as a stockholder
with respect to any Option Shares prior to their issuance.
   4. Restrictions on the Option and the Option Shares.  The Option and Option
Shares shall be subject to the following restrictions:
   (a)   Limitations on Transfers.  Neither the Option nor any interest or
expectancy in the Option Shares prior to their issuance may be transferred in
whole or in part except:
   (i)   By the Optionee's last will and testament; or pursuant to the laws
      of descent and distribution; or
   (ii)  By gift or under a domestic relations order to any child, stepchild,
      grandchild, parent, stepparent, grandparent, spouse, former spouse,
      sibling, niece, nephew, mother-in-law, father-in-law, son-in-law,
      daughter-in-law, brother-in-law or sister-in-law, including adoptive
      relationships, any person sharing the Optionee's household other than a
      tenant or employee, a trust in which these persons have more than fifty
      percent of the beneficial interest, a foundation in which these persons
      or the Optionee control the management of assets, and any other entity
      in which these persons or the Optionee own more than fifty percent of
      the voting interests (collectively, "Family Members").
Spartech may require appropriate written evidence of such transfer as a
condition of recording any such change of ownership on its books.  Spartech
shall not be required to recognize any such transfer until the transfer is duly
recorded on its books.
   (b)   No Pledges.  Neither the Option nor any interest or expectancy in the
Option Shares prior to exercise may be pledged, hypothecated, or otherwise used
as collateral to secure the payment of any debt.
   (c)   Spartech's Repurchase Rights.  If, either during the Optionee's
Employment or within one year after the termination of the Optionee's Employment
(regardless of the reason for termination or which part initiates it), the
Optionee directly or indirectly engages in any Detrimental Activity, Spartech
shall have the right to repurchase from the Optionee any Option Shares acquired
pursuant to exercise of the Option, subject to the limitations below, at a price
equal to the Exercise Price of such Option Shares without regard to any tax
effects of the exercise or the repurchase.  This repurchase right shall only
apply to Option Shares acquired pursuant to the Option within one year preceding
Spartech's notice to the Optionee of its exercise of the right, and only to
Option Shares still owned by the Optionee, and to exercise the right, Spartech
must give the Optionee written notice of its election to exercise the right,
specifying the nature of the Detrimental Activity, not later than one year after
termination of the Optionee's Employment.

      or instructions concerning the Optionee's employment; or
   (v)   Any other act or circumstance constituting "cause" under any

   (iv)  Disclosing to anyone outside Spartech, or using in other than

   (v)   Refusing to disclose promptly and to assign to Spartech at its
      request all right, title and interest in any invention or idea,
      patentable or not, made or conceived by the Optionee during his or her
      Employment, relating in any manner to the actual or anticipated
      business, research or development work of Spartech, or refusing to do
      anything reasonably requested by Spartech to enable it to secure a
      patent where appropriate in the United States and in other countries;
      or
   (vi)  Engaging in activity that results in termination of the Optionee's
      Employment for Cause.
   (d)   "Disability" means, in Spartech's sole discretion, either (A) the
Optionee's permanent and total disability as defined in Section 22(e)(3) of the
Internal Revenue Code and as determined consistent with the Code and the

Optionee incapable of continuing his or her usual and customary employment for a

more in any consecutive period of 240 days, which may be determined conclusively
for purposes of the Option by a licensed physician chosen by Spartech, or (C)
the commencement of payment of permanent disability benefits under any
disability insurance policy maintained for the benefit of the Optionee.
   (e)   "Employment" means substantially full-time employment by Spartech or a
subsidiary.  In this regard, the transfer of the Optionee's employment between
Spartech and a subsidiary or between subsidiaries shall not be deemed to be a
termination of Employment.  Moreover, the Optionee's Employment shall not be
deemed to have been terminated because of absence from active employment on
account of temporary illness or authorized vacation or temporary leaves of
absence from active employment granted by Spartech or a subsidiary for reasons
of professional advancement, education, health, or government service, or during
military leave for any period if the Optionee returns to active employment
within 90 days after the termination of military leave, or during any period
required to be treated as a leave of absence by virtue of any valid law or
agreement.  The Committee's determination in good faith regarding whether a
termination of Employment has occurred shall be conclusive.
   (f)   "Retirement" means the permanent withdrawal of the Optionee from the
conduct of regular, active business activities, on or after the Optionee reaches
the age of 60.  Retirement does not preclude part-time employment, consulting,
service as a non-employee director, passive activities such as the management of
the Optionee's investments, or other activities expressly approved by Spartech's
Chief Executive Officer.  For purposes of Section 1, if an Optionee whose
Employment has terminated by reason of Retirement subsequently engages in
business activities inconsistent with Retirement, the Option shall be construed
as if the Optionee had voluntarily terminated his or her Employment on the date
such subsequent business activities commence.
   6. Securities Law Restrictions.  The Optionee agrees that if at the time of
acquisition or delivery of any Option Shares issued hereunder the sale of such
shares is not covered by an effective registration statement filed under the
Securities Act of 1933 (the "Act"), the Optionee will acquire the Option Shares
for the Optionee's own account and without a view to resale or distribution in
violation of the Act or any other securities law, and that the Optionee will
enter into such written representations, warranties and agreements as Spartech
may reasonably request in order to comply with the Act or any other securities
law or with the Option.
   7. Reorganization of Spartech; Adjustment of Option Shares.  The existence of
the Option shall not affect in any way the right or power of Spartech or its
stockholders to make or authorize any or all adjustments, recapitalizations,
reorganizations or other changes in Spartech's capital structure or its
business, or any merger or consolidation of Spartech, or any issue of bonds,
debentures, preferred or prior preference stock ahead of or affecting the Option
Shares or the rights thereof, or the dissolution or liquidation of Spartech, or
any sale or transfer of all or any part of Spartech's assets or business, or any
other corporate act or proceeding, whether of a similar character or otherwise.
However, if the Common Stock is subdivided, consolidated, increased, decreased,
changed into or exchanged for a different number or kind of shares or other
securities, whether through reorganization, merger, recapitalization,
reclassification, capital adjustment or otherwise, or if Spartech shall issue
common stock or other securities as a dividend or upon a stock split, then for
all purposes, references herein to Common Stock or to Option Shares shall mean
and include all securities or other property (other than cash) that holders of
the Common Stock are entitled to receive in respect of the Common Stock by
reason of each such event, which securities or other property (other than cash)
shall be treated in the same manner and shall be subject to the same
restrictions as the underlying Option Shares.  Any such adjustment shall be made
without change in the total Exercise Price applicable to the unexercised portion
of the Option, but in computing any adjustment hereunder, any fractional share
or other security which might otherwise become subject to issuance may be
eliminated.  Any adjustments pursuant to this section may be determined by the
Committee, whose determination as to what, if any, adjustment shall be made
shall be final, binding and conclusive.
   8. No Guarantee of Employment or Other Contract Right.  The Option is not a
contract of employment, and neither the Option nor the Plan shall confer upon
the Optionee any right with respect to continuance of Employment or other
service with Spartech or any subsidiary, or interfere in any way with any right
Spartech or any subsidiary would otherwise have to terminate the Optionee's
Employment or other service.  Receipt of the Option shall not be deemed to
create a right to receive any future incentive award, and shall not constitute
an acquired labor right for purposes of any foreign law.  The Option is not a
part of the Optionee's salary or wages and shall not afford the Optionee any
additional right to severance payments or other termination awards or
compensation under any Spartech policy or any domestic or foreign law as a
result of the termination of the Optionee's employment for any reason
whatsoever.
   9. Amendment and Termination.  No amendment or termination of the Option
which would impair the rights of the Optionee may be made without the written
consent of the Optionee.  No amendment or termination of the Plan may impair the
rights of the Optionee under the Option without the written consent of the
Optionee.
   10.   Severability.  If any provision of the Option shall be held illegal,
invalid, or unenforceable for any reason, such provision shall be fully
severable and shall not affect the remaining provisions of the Option, and the
Option shall be construed and enforced as if the illegal, invalid, or
unenforceable provision had never been included herein.
   11.   Governing Law.  The Option shall be construed in accordance with the
laws of the State of Missouri.


                                End of Exhibit A
