whether or not fixed as to liability or liquidated as to amount, with respect to
which such party has been given written notice prior to the Survival Date or
such thirtieth day after the expiration of the applicable statute of limitations
(or extensions or waivers thereof), whichever shall be applicable thereto in
accordance with this Section 8.1.

      8.2. INDEMNIFICATION BY STOCKHOLDER. Stockholder and InterSystems shall
jointly and severally indemnify, defend, protect and hold harmless Compounding
Innovation and the Company, each of their respective successors and assigns and
each of their respective directors, officers, employees, attorneys, agents and
affiliates (each a "Compounding Innovation Indemnified Person"), at all times
from and after the date of this Agreement (subject to any limitation on the
survival of representations and warranties set forth in Section 8.1) against all
losses, claims, damages, actions, suits, proceedings, demands, assessments,
adjustments, costs and expenses ("Losses") (including specifically, but without
limitation, reasonable attorneys' fees and expenses of investigation ("Legal
Expenses")) based upon, resulting from or arising out of (a) any inaccuracy or
breach of any representation or warranty of Stockholder or InterSystems
contained in this Agreement (it being understood that, notwithstanding anything
to the contrary contained in this Agreement, to determine if there has been an
inaccuracy or breach of a representation or warranty of Stockholder or
InterSystems and the Losses arising from such inaccuracy or breach, such
representation or warranty shall be read as if it were not qualified by
materiality, including, without limitation, qualifications indicating accuracy
"in all material respects" or accuracy except to the extent the inaccuracy will
not have a "Material Adverse Effect") and (b) the breach by Stockholder or
InterSystems of, or the failure by Stockholder or InterSystems to observe, any
of the covenants or other agreements contained in this Agreement; provided,
however, that Compounding Innovation shall have no recourse against the
Stockholder or InterSystems unless and to the extent the aggregate amount of its
claims under this Agreement exceeds $50,000. Stockholder's and InterSystems'
aggregate liability in respect of all claims for breach of representations and
warranties shall not exceed $700,000 in the aggregate.

      8.3. INDEMNIFICATION BY COMPOUNDING INNOVATION OR THE COMPANY. Compounding
Innovation and the Company shall jointly and severally indemnify, defend,
protect and hold harmless Stockholder and InterSystems, their successors and
assigns and each of their respective directors, officers, employees, attorneys,
agents and affiliates (each a


                                       23
<PAGE>
"Stockholder Indemnified Person") at all times from and after the date of this
Agreement (subject to any limitation on the survival of representations and
warranties set forth in Section 8.1) against all Losses (including specifically,
but without limitation, Legal Expenses) based upon, resulting from or arising
out of (a) any inaccuracy or breach of any representation or warranty of
Compounding Innovation contained in this Agreement, (b) the breach by
Compounding Innovation of, or the failure by Compounding Innovation to observe,
any of its covenants or other agreements contained in or made pursuant to this
Agreement, (c) the breach by the Company or the failure by the Company to
observe any of its covenants and agreements set forth in Article 5, and (d) the
conduct of the Company after the Closing.

      8.4. INDEMNIFICATION PROCEDURES.

            (a) Promptly after receipt by any person entitled to indemnification
under Section 8.2 or 8.3 (an "indemnified party") of notice of the commencement
of any action, suit or proceeding by a person not a party to this Agreement in
respect of which the indemnified party will seek indemnification hereunder (a
"Third Party Action"), the indemnified party shall notify the person that is
obligated to provide such indemnification (the "indemnifying party") thereof in
writing, but any failure to so notify the indemnifying party shall not relieve
it from any liability that it may have to the indemnified party under Section
8.2 or 8.3, except to the extent that the indemnifying party is prejudiced by
the failure to give such notice. The indemnifying party shall be entitled to
participate in the defense of such Third Party Action and to assume control of
such defense (including settlement of such Third Party Action) with counsel
reasonably satisfactory to such indemnified party; provided, however, that:

                  (i) the indemnified party shall be entitled to participate in
the defense of such Third Party Action and to employ counsel at its own expense
(which shall not constitute Legal Expenses for purposes of this Agreement) to
assist in the handling of such Third Party Action;

                  (ii) the indemnifying party shall obtain the prior written
approval of the indemnified party before entering into any settlement of such
Third Party Action or ceasing to defend against such Third Party Action, if
pursuant to or as a result of such settlement or cessation, injunctive or other
equitable relief would be imposed against the indemnified party or the
indemnified party would be materially adversely affected thereby;

                  (iii) no indemnifying party shall consent to the entry of any
judgment or enter into any settlement that does not include as an unconditional
term thereof the giving by each claimant or plaintiff to each indemnified party
of a release from all liability in respect of such Third Party Action; and

                  (iv) the indemnifying party shall not be entitled to control
the defense of any Third Party Action unless the indemnifying party confirms in
writing its assumption of such defense and continues to pursue the defense
reasonably and in good faith.

After written notice by the indemnifying party to the indemnified party of its
election to assume control of the defense of any such Third Party Action in
accordance with the foregoing, (i) the indemnifying party shall not be liable to
such indemnified party hereunder for any Legal Expenses subsequently incurred by
such indemnified party attributable to defending against such


                                       24
<PAGE>
Third Party Action, and (ii) as long as the indemnifying party is reasonably
contesting such Third Party Action in good faith, the indemnified party shall
not admit any liability with respect to, or settle, compromise or discharge the
claim underlying, such Third Party Action without the indemnifying party's prior
written consent. If the indemnifying party does not assume control of the
defense of such Third Party Action in accordance with this Section 8.4, the
indemnified party shall have the right to defend and/or settle such Third Party
Action in such manner as it may deem reasonably appropriate at the cost and
expense of the indemnifying party provided that the indemnifying party has
received written notice of the proposed settlement and the terms thereof, and
the indemnifying party will promptly reimburse the indemnified party therefor in
accordance with this Section 8. The reimbursement of fees, costs and expenses
required by this Section 8 shall be made by periodic payments during the course
of the investigation or defense, as and when bills are received or expenses
incurred.

            (b) If an indemnified party becomes entitled to any indemnification
from an indemnifying party pursuant to this Agreement, such indemnification
payment shall be made in cash upon demand.

            (c) If an indemnified party has actual knowledge of any facts or
circumstances other than the commencement of a Third Party Action which cause in
good faith it to believe that it is entitled to indemnification under this
Section 8, then such indemnified party shall promptly give the indemnifying
party notice thereof in writing, but any failure to so notify the indemnifying
party shall not relieve it from any liability that it may have to the
indemnified party under Section 8.2 or 8.3, as the case may be, except to the
extent that the indemnifying party is prejudiced by the failure to give such
notice.

            (d) All payments made under this Section 8 shall be made by wire
transfer in immediately available funds in U.S. dollars.

            (e) The parties hereto agree that if InterSystems or Stockholder
becomes liable to any Compounding Innovation indemnified party pursuant to
Section 8.2 hereof, Compounding Innovation shall have the right, in addition to
Compounding Innovation rights hereunder, at law or in equity, to withhold or
offset any amount payable to Stockholder under the Promissory Note and/or
Guaranty delivered to Stockholder pursuant to this Agreement, but only to the
extent of such liability and in no event shall Compounding Innovation or the
Company withhold or offset an amount in excess of $150,000 in the aggregate
under the Promissory Note. Neither Compounding Innovation nor the Company will
offset any amount payable to Stockholder pursuant to Section 1 hereof or with
respect to any similar relationship with Mytex or its Affiliates for the benefit
of Mytex.

            (f) Notwithstanding anything to the contrary herein, an indemnifying
party shall not be liable for Losses arising out of or in connection with any
matter described in this Section 8 if and to the extent such Losses are covered
by a policy of insurance or benefits from a right to indemnification from a
Person not a party to this Agreement and payment is made under such policy to
the indemnified party by the insurer or under such right to indemnification by
such Person, as applicable.


                                       25
<PAGE>
            (g) The remedies provided in this Section 8 shall be the exclusive
remedy for monetary damages (whether at law or in equity) with respect to
matters subject to indemnification under Section 8.2(a) or Section 8.3(a)
hereof.

9.    NONCOMPETITION

      9.1. PROHIBITED ACTIVITIES.

      Stockholder and InterSystems hereby jointly and severally covenant,
acknowledge and agree as follows:

            (a) For a period of five (5) years after the Closing (except as set
forth in the following paragraph), neither Stockholder nor InterSystems nor any
of their Affiliates shall for any reason whatsoever, directly or indirectly, for
itself or on behalf or in conjunction with any other person, persons, company,
partnership, corporation or business of whatever nature engage, as a
shareholder, owner, partner, joint venturer, or in any capacity, whether as a
contractor, consultant or advisor in any plastic compounding business that is
located in the United States of America.

Notwithstanding the foregoing provisions of this paragraph, Stockholder may (i)
be a passive investor owning no more than 5% of the outstanding equity
securities of any corporation the equity securities of which are listed on a
national securities exchange or traded on the NASDAQ National Market System and
with which Stockholder has no other connection whatsoever or (ii) provide
financial assistance to any Person pursuant to a factoring or other lending
arrangement provided such arrangement does not result in Stockholder,
InterSystems or their respective affiliates owning securities representing (or
convertible into) more than 5% of the outstanding equity securities of such
entity;

            (b) For a period of five (5) years neither InterSystems nor
Stockholder shall and shall cause each of its Affiliates not to, offer to employ
any person who is, at that time, or who has been within one (1) year prior to
that time, an employee of Compounding Innovation or the Company;

            (c) For a period of five (5) years after the Closing Date, neither
InterSystems nor Stockholder shall and shall cause each of its Affiliates to,
engage or participate in any effort or act to induce any customer, supplier,
associate, employee, sales or other agent or independent contractor of
Compounding Innovation or the Company or which has been a customer, supplier,
employee, sales or other agent or independent contractor of Compounding
Innovation or the Company within one (1) year prior to that time, to take any
action which might be disadvantageous to Compounding Innovation or the Company,
or to not take any action which might be advantageous to Compounding Innovation
or the Company in the plastics compounding business;

            (d) Stockholder and InterSystems acknowledge that the damages that
would be suffered by Compounding Innovation as a result of any breach of the
provisions of this Section 9.1 may not be calculable and that an award of a
monetary judgment for such a breach would be an inadequate remedy. Consequently,
Compounding Innovation shall have the right, in addition to any other rights it
may have, to obtain, in any court of competent jurisdiction, injunctive relief
to restrain any breach or threatened breach of any provision of this Section 9.1
or otherwise to


                                       26
<PAGE>
specifically enforce any of the provisions hereof, and Compounding Innovation
shall not be obligated to post a bond or other security in seeking such relief.
This remedy is in addition to damages directly or indirectly suffered by
Compounding Innovation and reasonable attorneys fees;

            (e) It is agreed by the parties that the foregoing covenants in this
Section 9.1 impose a reasonable restraint on InterSystems and Stockholder in
light of the activities and business of the Company and Compounding Innovation
on the date of the execution of this Agreement and the current plans of
Compounding Innovation; and

            (f) The parties hereto agree that the duration and area for which
the covenants in this Section 9.1 are to be effective are reasonable. In the
event that any court finally determines that the time period or the geographic
scope of any such covenant is unreasonable or excessive and any covenant is to
that extent made unenforceable, the parties agree that the restrictions of this
Section 9.1 shall remain in full force and effect for the greatest time period
and within the greatest geographic area that would not render it unenforceable.
The parties intend that each of the covenants in Sections 9.1 (a), (b), (c), (d)
and (e) shall be deemed to be a separate covenant.

            9.2. INDEPENDENT COVENANT. All of the covenants in this Section 9
shall be construed as an agreement independent of any other provision of this
Agreement, and the existence of any claim or cause of action of Stockholder or
InterSystems against the Company or Compounding Innovation, whether predicated
on this Agreement or otherwise, shall not constitute a defense to the
enforcement by Compounding Innovation or the Company of such covenants. It is
specifically agreed that the period of five (5) years stated above, shall be
computed by excluding from such computation any time during which any
Stockholder is in violation of any provision of this Section 9 and any time
during which there is pending in any court of competent jurisdiction any action
(including any appeal from any judgment) brought by any person, whether or not a
party to this Agreement, in which action Compounding Innovation or the Company
seeks to enforce the agreements and covenants of Stockholder or InterSystems in
this Section 9 or in which any person contests the validity of such agreements
and covenants or their enforceability or seeks to avoid their performance or
enforcement.

      9.3. MATERIALITY. Stockholder hereby agrees that this covenant is a
material and substantial part of this transaction.
