        collect from its customers shall be paid by RAICHEM upon payment of the
        purchase price for the PRODUCT, or in lieu of this, RAICHEM shall
        provide to pHoenix a duty or tax exemption certificate acceptable to

                (b) In the event that PRODUCTs are sold in the form of
        combination products (PRODUCT sold in combination with a second
        discrete product sold by RAICHEM), then profits for such combination
        products will be calculated by multiplying actual cash payments for
        such combination products by the fraction A/(A+B) where A is the
        average invoice price (to third parties) during the previous month for
        the PRODUCTs when sold separately, and B is the average invoice price
        of any other active component or components manufactured or sold by
        RIACHEM in the combination when sold separately. If the active
        component(s) in the combination that are not PRODUCTs are not sold
        separately by RAICHEM, then profits shall be calculated by multiplying
        actual cash payments for such combination products by the fraction A/C
        where A is the average invoice price (to third parties) of the PRODUCTs
        when sold separately and C is the average invoice price (to third
        parties) of the combination product.

Article 5. Labeling, Package Inserts and Packaging
           ---------------------------------------

5.1     Labeling & Packaging. pHoenix shall deliver the PRODUCTs to RAICHEM in

        from the specifications or quality control standards, pHoenix shall be
        notified and provided with samples of the PRODUCTs tested. If,
        following a review of the test results and after conducting its own
        tests of the sample, pHoenix agrees that such sample does not conform
        to said specifications or quality control standards, pHoenix shall
        provide RAICHEM, free of any additional charge, with new deliveries of
        the same quantity of the PRODUCTs as the one from which the random
        sample were taken. RAICHEM shall return, at pHoenix's expense, the
        particular lot or shipment of the PRODUCT which does not comply with
        the aforesaid specifications or quality control standards. If, after
        investigation, pHoenix disagrees with RAICHEM, then the parties shall
        agree upon a mutually acceptable method to determine whether or not the
        Products should be accepted by RAICHEM. If the parties fail to agree
        upon a method within ten business days, then the parties shall promptly
        agree upon an independent quality control laboratory (the "Laboratory")
        to conduct an inspection of the PRODUCTs for purposes of determining if
        the PRODUCTs should be accepted by RAICHEM or replaced, at no charge,
        by pHoenix. The determination of the Laboratory shall be final and
        binding upon the parties and the party that was proven incorrect in its
        inspection analysis shall bear the entire cost of the Laboratory
        inspection.

6.2     PRODUCT Modification. Throughout the term of this Agreement, pHoenix
        may desire to make certain changes in the performance or appearance of

        Proprietary Rights only for so long as this Agreement is in effect.

9.3     Infringement. pHoenix shall undertake at pHoenix's own expense the
        defense of any suit or action for infringement of pHoenix's patents or

        the sale of any PRODUCTs, provided that RAICHEM shall have promptly
        advised pHoenix in writing of each notice or claim of infringement
        received by RAICHEM and of the commencement of the suit or action.
        pHoenix shall hold RAICHEM harmless from damages or other sums which

        be infringing on a third-party patent, pHoenix will negotiate in good
        faith with the third party to obtain a license to use the third party's
        technology and, if pHoenix fails to obtain such a license, or if

        the right to either terminate this Agreement by giving written notice
        of termination to pHoenix, and return for full credit all inventory on
        hand, or negotiate with the infringed party for such a license.

        party patent shall exclude RAICHEM's costs involved in negotiation with
        any infringed party for such a license.

        plant.

        immediately notify the other party in writing should it become aware of
        any defect or condition that may render the PRODUCT(s) supplied by
        pHoenix in violation of the U.S. Food, Drug and Cosmetic Act, or of a
        similar law of any jurisdiction where the PRODUCT is sold by RAICHEM.
        The parties shall share with each other all data on the PRODUCT
        complaints including, but not limited to, complaints or information
        regarding performance and/or allegations or reports of any negative
        effect from the use or misuse of the PRODUCTs as soon as such data is
        available. Each party will assist the other in resolving RAICHEM's
        customers' complaints. However, RAICHEM shall have sole responsibility
        and authority to interact directly with RAICHEM's customers in the
        resolution of such complaints, and pHoenix shall be responsible only
        for interacting with RAICHEM in such matters.

        THE SOLE EXCLUSIVE WARRANTIES PROVIDED TO RAICHEM AND TO CONSUMERS AND
        ARE IN LIEU OF ALL OTHER WARRANTIES, WHETHER WRITTEN OR ORAL, IMPLIED

        AND WORKMANSHIP UNDER THE NORMAL USE AND SERVICE FOR WHICH IT WAS
        DESIGNED, FOR THE SHELF LIFE PERIOD DEFINED IN APPENDIX A, pHoenix'S

Article 12. Confidentiality
            ---------------

12.1    Confidentiality. For purposes of this Agreement, the term "Confidential
        Information" shall mean all documents, clearly marked as "PROPRIETARY"
        or "CONFIDENTIAL" , relating to the respective products and businesses
        of the parties which (i) is disclosed, upon request, by one party
        hereto to the other and (ii) is claimed by the disclosing party to be
        secret, confidential and proprietary to the disclosing party.

        During the Agreement Term and for a period of one year thereafter, each
        party (except as is explicitly otherwise required hereby) shall keep
        confidential, shall not use itself or for the benefit of others and
        shall not copy or allow to be copied, in whole or in part , any
        Confidential Information disclosed to such party by the other.

        The obligations of confidentiality imposed upon the parties by the
        foregoing paragraph shall not apply with respect to any alleged
        Confidential Information which:

        (a)   is known to the recipient thereof prior to receipt thereof from
              the other party hereto (as evidenced by said recipient's written
              or other recorded records);

        (b)   is disclosed to said recipient by a third party who has the right
              to make such disclosure;

        (c)   is or becomes a part of the public domain or public knowledge
              through no fault of the said recipient;

        (d)   is independently developed by the recipient (as evidenced by said
              recipient's written or other recorded records); and

        (e)   is required to be disclosed under operation of law.

Article 13. Termination
            -----------

13.1    Termination For Cause. Either party will have the right to terminate
        this Agreement if the other party (a) assigns this Agreement or any of
        its rights hereunder in violation of the provisions of this Agreement,
        or (b) becomes bankrupt or insolvent, or (c) makes an assignment for
        the benefit of creditors, or a receiver, trustee in bankruptcy or
        similar officer appointed to take charge of all or part of its
        property, and such event has not been cured within thirty (30) days of
        written notice thereof by the non-breaching party. If either party
        materially breaches this Agreement, including, but not limited to
        either party's failure to adhere to the confidentiality provisions and
        restrictions on use of information set forth in this Agreement, then
        notwithstanding any other provision of this Agreement, no cure period
        shall be allowed and the non-breaching party shall be entitled to
        terminate this Agreement immediately.

13.2    Termination For Failure to meet Minimum Purchases. pHoenix shall have
        the right to terminate this Agreement upon three (3) months written
        notice at any time if RAICHEM fails to meet its minumin purchases as
        stated in this Agreement.

13.3    Rights and Obligations on Termination. Upon termination of this
        Agreement, RAICHEM shall immediately discontinue any previously
        authorized use of any of pHoenix's Proprietary Rights and shall
        immediately cease all conduct that might cause anyone to believe that
        RAICHEM is authorized to market or sell PRODUCTs or otherwise connected
        with pHoenix, and pHoenix may itself or through others, commence sale,
        distribution and service of PRODUCTs in the TERRITORY. Termination of
        this Agreement for any reason whatsoever shall not relieve either of
        the parties hereto from making payment of monies due to the other from
        fulfilling obligations incurred up to the effective date of termination
        or as otherwise expressly provided in this Agreement.

13.4    Termination or Expiration Damages. Neither pHoenix nor RAICHEM shall be
        liable to the other, or to any other business entity solely by reason
        of the expiration or termination of this Agreement regardless of the
        rationale for or propriety of any termination or expiration. The
        exculpation from liability shall be for any losses or damages of any
        kind whatsoever, including, but not limited to, direct, indirect,
        special, consequential or incidental damages sustained by reason of
        such termination, including but not limited to, any claim for loss of
        compensation or profits or for loss of prospective compensation or
        prospective profits in respect of sales of any of the PRODUCTs or on
        account of any expenditures, investments, leases, capital improvements
        or any other commitments made by either party in connection with their
        respective business made in reliance upon or by virtue of this
        Agreement or otherwise.

            ----------------------------------------

        all claims made or to be made regarding PRODUCTs' performance.

14.2    Inquiries. Each party shall keep the other informed of any formal or
        informal inquiry relating to PRODUCTs sold hereunder by any regulatory
        agency of any state or national government.

14.3    PRODUCT Recall. Should PRODUCT performance or any governmental action
        require the recall or withholding from market of PRODUCT sold by
        pHoenix to RAICHEM, RAICHEM shall bear the costs and expenses of recall
        if such recall is the result of any fault or omission attributable to
        RAICHEM and pHoenix shall bear the costs and expenses of recall if such
        recall is the result of any fault or omission attributable to pHoenix.
        Should such recall result from the equal fault of both parties, or
        should it prove impossible to assign fault to the satisfaction of both
        parties, the parties shall share the said costs and expenses equally.

Article 15. Arbitration
            -----------

15.1    Any controversy or claim arising under or in relation to this
        Agreement, except as otherwise expressly provided below, shall be
        settled exclusively by arbitration in accordance with the International
        Arbitration Rules of the American Arbitration Association (AAA). There
        shall be three arbitrators: one selected by PHoenix, one selected by
        RAICHEM, and one selected by the parties jointly or, failing their
        agreement, selected pursuant to the rules of the AAA. The arbitration
        shall be conducted in English and shall be held in Massachusetts. The
        prevailing party shall be entitled to recover its costs and attorneys'
        fees. The decision of the arbitrators shall be final and binding on the
        parties, and judgment upon the award rendered by the arbitrators may be
        entered by any court having jurisdiction thereof. The provisions of
        this arbitration clause shall not be applied to the determination of
        questions affecting the validity or scope of any trademarks or other
        intellectual property rights.

Article 16. General Provisions
            ------------------

16.1    Entire Agreement. This Agreement, including the Appendices, constitutes

        otherwise herein) except by a writing duly signed by both parties.

16.2    Assignment, Waiver, Severability. Neither party may assign this
        Agreement without the prior written consent of the other party. Failure
        by either party to enforce any term hereof shall not be deemed a waiver
        of future enforcement of that or any other term. If any provision of
        this Agreement is declared void or unenforceable by any judicial,
        administrative or arbitration authority, such action will not nullify
        the remaining provisions of this Agreement.

16.3    Governing Law. This Agreement shall be governed and construed under and
        according to the laws of the Commonwealth of Massacusetts, U.S.A.,
        excluding its choice of laws rules.

16.4    Relationship Created. The relationship of the parties is that of
        independent contractors. Nothing in this Agreement shall be construed
        as establishing an agency, joint venture or partnership between the
        parties. Each party is an independent entity, and shall have sole
        responsibility for its employees, even while such employees are on the
        premises of the other party's facility(ies). Neither RAICHEM nor
        pHoenix shall have the right to enter into any contracts or commitments
        or to make any representations or warranties, whether express or
        implied, in the name of or on behalf of any other party, or to bind any
        other party in any respect whatsoever, unless agreed to in writing or
        expressly permitted in this Agreement.

16.5    Authority. Each party hereby represents and warrants that it has full
        power and authority to enter into and perform this Agreement, without
        any governmental approvals, and that its entering into and performance
        of this Agreement will not conflict with any other agreement to which
        it is a party or by which it is bound.

16.6    Notice. Any written notice, or statement, necessary or appropriate
        under this Agreement shall be deemed to be properly given if delivered
        personally in writing or sent by registered or certified mail to the
        party to be notified at the address set forth above or at such other
        address as either party may hereafter designate in writing.

16.7    Captions. The captions or paragraph headings of this Agreement do not
        constitute any substantive part of this Agreement and shall not be
        considered in the construction or interpretation of this Agreement.

16.8    Force Majeure. Each party hereto shall be excused from the performance
        of its obligations hereunder in the event such performance is prevented
        by force majeure, and such excuse shall continue for so long as the
        condition constituting such force majeure and any consequences
        resulting from such condition continues. In addition, in the event the
        condition constituting the force majeure causes a substantial inability
        by either party hereto to meet its obligations hereunder, the term of
        this Agreement may, upon written agreement of both parties, be
        suspended for the period of such inability, but not to exceed six (6)
        months. For the purposes of this Agreement, force majeure shall mean
        causes beyond either party's control including, without limitation,
        acts of God; regulations or laws of any government; war, riot or civil
        commotion; damage to or destruction of production facilities or
