                discloseable by TIMERx Technologies without violation of duties
                of confidentiality owed to third parties), together with all
                intellectual property and other rights and interests of TIMERx
                Technologies and its Affiliates thereto and therein in the
                Territory. For the avoidance of doubt Sanofi Test and Regulatory
                Data are excluded from this definition.

        1.33.   "TIMERx TRADEMARK(S)" shall mean those names, symbols and or
                characters described in Exhibit 1.33 hereto, as the same may be
                amended from time to time during the term of this Agreement by
                TIMERx Technologies on at least six (6) months' prior written
                notice to Sanofi, that are owned and registered (or are
                registrable) by TIMERx Technologies and that have been
                designated by it for use in conjunction with Sanofi's packaging
                and promotion of the Designated Product hereunder, pursuant to
                Section 5.2.

2.      GRANT OF LICENSE AND TRANSFER OF TECHNOLOGY.

        2.1.    TIMERx Technologies hereby grants to Sanofi a license under the
                TIMERx Technologies Patents and TIMERx Technologies'
                Confidential Technology disclosed to Sanofi hereunder and to all
                TIMERx Improvements, to manufacture, use and sell and register
                the Designated Product in the Territory during the License Term.
                Subject to Section 7.3, such license shall be exclusive for such
                purposes in each country during the Exclusivity Period for that
                country, and otherwise shall be nonexclusive. TIMERx
                Technologies hereby grants to Sanofi a nonexclusive license
                under the Product Production Technology to make and have made
                the Designated Product in the Territory during the License Term
                using Formulated TIMERx supplied by TIMERx Technologies or
                produced pursuant to the license under Section 7.6. Such
                licenses do not extend to the making of TIMERx or Formulated
                TIMERx, those matters being covered by Section 7.6. Sanofi shall
                have the right to grant sublicenses of its rights hereunder to
                any Affiliate(s) of Sanofi (and this Agreement shall thereby be
                binding upon and inure to the benefit of such Affiliate within
                the area of such sublicense), but shall otherwise have no right
                to grant sublicenses hereunder without the prior written consent
                of TIMERx Technologies in its discretion. TIMERx Technologies
                will, throughout the License Term, promptly notify Sanofi of all
                TIMERx Technologies Patents referred to in Subsection 1.31.2 and
                provide Sanofi with access to all of the same and to other
                TIMERx Improvements, solely for use within the scope of the
                license stated in this section.

        2.2.    TIMERx Technologies hereby grants Sanofi a nonexclusive, paid-up
                license, with right to sublicense as stated in Section 2.1,
                under all rights of TIMERx Technologies and its Affiliates in
                and to the TIMERx Technologies Test and Regulatory Data to use
                the same for purposes of complying with governmental
                requirements, but solely with respect to the Designated Product
                for marketing or use in the Territory. TIMERx Technologies
                hereby consents to Sanofi's and its permitted sublicensees'
                cross-referencing, in any PLA or other governmental filings made
                by them within the scope of such license, any ANDA, NDA or other
                PLA filing made or drug master file created by TIMERx
                Technologies or its Affiliates relating to or containing any of
                the TIMERx Technologies Test and Regulatory Data. The license
                and rights under this section shall survive any termination or
                expiration of the term of this Agreement, except a termination
                under Section 11.4 due to an uncured breach by Sanofi. TIMERx
                Technologies will, throughout the License Term and solely for
                use within the scope of the license stated in this section,
                provide to Sanofi on request access to all of the TIMERx
                Technologies Test and Regulatory Data in or coming into TIMERx
                Technologies' possession or otherwise reasonably available to
                it.

        2.3.    TIMERx Technologies will at its expense exert reasonable efforts
                to make knowledgeable personnel reasonably available within
                thirty (30) days from the later of the Effective Date or
                Sanofi's written request, to consult with Sanofi to the extent
                necessary to enable Sanofi to produce Designated Product for
                Sanofi and its Affiliates pursuant to this Agreement. The
                parties understand and agree that Sanofi's performance under
                this Agreement depends upon the communication of the Product
                Production Technology, and that, if for any reason, it is not
                possible to transfer such technology to Sanofi, this will not
                lead to liability on Sanofi's part. The Product Production
                Technology will be deemed to have been successfully transferred
                upon the satisfactory completion of the Phase II Dissolution
                Profile Studies.

3.      DEVELOPMENT AND REGULATORY PERIODS.

        3.1.    In consideration of TIMERx Technologies' entering into this
                Agreement, Sanofi shall pay TIMERx Technologies upon the
                Effective Date a nonrefundable initial fee of ********.

        3.2.    During the Development Period, TIMERx Technologies will exert
                all its reasonable efforts to complete the Phase I Dissolution
                Profile Studies and Sanofi will cooperate in such effort.
                ********** Phase I Dissolution Profile Studies (as more fully
                described in Exhibit 1.9), Sanofi will pay TIMERx Technologies a
                milestone fee of **********.

        3.3.    During the Development Period, Sanofi will exert all its
                reasonable efforts to complete the Phase II Dissolution Profile
                Studies as soon as is practicable, and TIMERx Technologies will
                cooperate in such effort. ********** Phase II Dissolution
                Profile Studies (as more fully described in Exhibit 1.9), Sanofi
                will pay TIMERx Technologies a milestone fee of **********.

        3.4.    Each party's Project Contact(s) will provide written reports to
                the other party's Project Contact(s) at least monthly throughout
                the Development Period and the Regulatory Period, stating in
                detail all efforts made and in process, and all significant
                progress achieved and difficulties encountered in the reporting
                party's portion of the development effort or regulatory efforts,
                as the case may be, since the last such report. Each of the
                Project Contacts will also be available throughout the
                Development Period and the Regulatory Period to answer any
                reasonable questions from the other party's Project Contacts, as
                appropriate.

        3.5.    Sanofi will supply to TIMERx Technologies, without charge, all
                Adalat LA and Designated Product reasonably required to support
                the development effort by TIMERx Technologies during the
                Development Period (other than Designated Product for the Phase
                I Dissolution Profile Studies, which shall be supplied by TIMERx
                Technologies at its expense), and TIMERx Technologies shall
                provide at its own expense all Formulated TIMERx reasonably
                required for such effort.

        3.6.    Throughout the Development Period and the Regulatory Period, the
                parties' Project Contacts and other relevant personnel (as
                determined in good faith by each party) shall attend project
                meetings to be held quarterly or on such other basis as may be
                mutually agreed. The sites for such meetings will alternate
                between Patterson, N.Y. and Guildford, Surrey (which is the
                location of Sanofi's Affiliate, Sanofi Winthrop Limited ("Sanofi
                Winthrop"), which will be the Sanofi branch with the closest
                relationship to this Agreement). Each party shall bear its own
                expenses of its personnel's travel, lodging and meals incurred
                in connection with attending such quarterly meetings. Each party
                shall bear its own expenses for all activities during the
                Development Period and the Regulatory Period, except that, if
                TIMERx Technologies personnel travel outside the Patterson, New
                York area during the Development Period or the Regulatory Period
                at the request of Sanofi and for the convenience of Sanofi,
                other than to attend such meetings, Sanofi shall bear all of the
                reasonable travel, lodging and meal expenses for such personnel,
                and if Sanofi personnel travel outside the Guildford, Surrey
                area during the Development Period or the Regulatory Period at
                the request of TIMERx Technologies and for the convenience of
                TIMERx Technologies, other than to attend such meetings, TIMERx

                shall bear all of the reasonable travel, lodging and meal
                expenses for such personnel.

4.      OTHER REGULATORY PERIOD PROVISIONS.

        4.1.    Promptly following approval by Sanofi of the Phase II
                Dissolution Profile Study for the Designated Product pursuant to
                Section 3.3 above, the Regulatory Period will begin. Sanofi
                will, during the Regulatory Period, exert all its reasonable
                efforts to perform the ********** and TIMERx Technologies will
                cooperate in such effort. As to scheduling, the parties
                understand that *************.

        4.2.    Subject to completion by Sanofi of the **********, Sanofi will
                exert all its continuing reasonable efforts to obtain and retain
                marketing approval for the Designated Product throughout the
                Territory, including, at its expense, the preparation and filing
                during and after the Regulatory Period of PLAs for the
                Designated Product with the relevant Regulatory Authorities
                throughout the Territory, and the prosecution of the same
                successfully to the granting of marketing approvals from such
                authorities for the Designated Product. As the term is used in
                this Section 4, the exertion of all Sanofi's reasonable efforts
                will mean that (i) Sanofi will exert on a continuing basis such
                reasonable efforts as would be normal for sponsors or applicants
                for regulatory approval of drugs under PLAs generally, and (ii)
                this project will receive a priority at least as high as any of
                Sanofi's other generic drug development efforts (if such a
                priority would lead to the exertion of greater efforts than
                those described in clause (i)).

        4.3.    Each party will cooperate with the other throughout the
                Regulatory Period and may at its discretion provide to the other
                party all information in or coming into its possession or
                reasonably available to it which it considers useful to support
                the goals of the Regulatory Period. Without prejudice to its
                obligations under this Agreement, each party understands and
                agrees that the other does not warrant or commit that the
                Designated Product will be successfully developed, nor that, if
                developed, that it will be successfully registered in any county
                or countries, and neither party shall have any liability or
                responsibility to the other or to third parties for any such
                failure of the development process hereunder.

        4.4.    In addition to the fees payable in Section 3.1, 3.2, and 3.3,
                and in consideration of TIMERx Technologies' entering into this
                Agreement, Sanofi agrees to pay TIMERx Technologies the
                following non-refundable fees:

                4.4.1   a milestone fee payable within ********** in the
                        Territory, in the amount of **********; and

                4.4.2   another milestone fee, also in the amount of **********,
                        payable within ********** in the Territory.

        4.5.    Except as otherwise provided in this Section 4, each party shall
                bear its own expenses for all activities during the Regulatory
                Period, provided, however that TIMERx Technologies shall provide
                to ************, and reasonable quantities of Designated Product
                ********** for purposes of comparing therewith the Designated
                Product manufactured by Sanofi in dissolution profile testing
                and finished product quality control testing, and provided
                further, however, that Sanofi shall provide at its own expense
                all other Designated Product and other materials and
                manufacturing and testing services reasonably required to
                support the testing and certification effort.

        4.6     Except as provided in Section 4.7, Sanofi shall be responsible
                for, and hereby agrees to conduct or arrange for, at Sanofi's
                expense, all testing and studies during the Regulatory Period,
                including as to efficacy, bioavailability, bioequivalence, and
                safety and any other necessary testing, in connection with the
                development, manufacture and marketing of the Designated
                Product, and for compliance with all requirements imposed by any
                Regulatory Authority or otherwise by the government of any
                country in the Territory with respect to the Designated Product
                provided that TIMERx Technologies shall have promptly and
                throughout the Regulatory Period provided to Sanofi all
                necessary information in or coming into TIMERx Technologies'
                possession and available to it in support of the completion of
                such testing.

        4.7     If one or more Regulatory Authorities, following Sanofi's filing
                of a PLA with it or them, require additional tests or studies,
                ******************************* (i.e., ************), *****
                ************* shall be borne entirely by Sanofi, within the
                context and limits of its agreement hereunder to exert all
                reasonable efforts to obtain marketing approval for the
                Designated Product.

        4.8     It is understood and agreed that the Specifications for
                Formulated TIMERx for Designated Product to be sold in the
                United Kingdom and outside the United Kingdom shall be the same,
                because this will be required for the technically satisfactory
                production, regulatory approval, and exploitation of the
                Designated Product. Accordingly, in no event will Sanofi permit
                the Designated Product to be certified for sale anywhere in the
                Territory on any other basis, unless TIMERx Technologies has
                consented thereto in writing after detailed consultation

                with Sanofi. It is understood, however, that the Regulatory
                Authority in the respective countries of the Territory may
                require differing tests and certificates of analysis on the
                Formulated TIMERx to be provided hereunder with respect to
                Designated Products to be sold in those countries, and in such
                event the parties shall agree on how to proceed.

        4.9     Sanofi's Project Contacts will provide written reports to TIMERx
                Technologies' Project Contacts, as appropriate, at least monthly
                throughout the Regulatory Period, stating in detail all efforts
                made and in process, and all significant progress achieved and
                difficulties encountered in the certification effort since the
                last such report. Sanofi's Project Contacts will also be
                available throughout the Regulatory Period to answer any
                reasonable questions from TIMERx Technologies' Project Contacts,
                as appropriate.

5.   MARKETING PERIOD.

        5.1.    Subject to the granting of all necessary governmental approvals
                or concurrences to sell the Designated Product, Sanofi hereby
                agrees, during the Marketing Period, to use all continuing
                reasonable efforts to market and sell the Designated Product
                throughout the portion of the Territory for which its sale has
                been approved.

                accordance will all applicable laws and regulations in the
                Territory. Provided that the TIMERx Trademarks remain registered
                in the countries listed in Exhibit 1.33, and that TIMERx
                Technologies undertakes reasonable efforts to protect and defend
                the same in such countries, Sanofi agrees to market the
                Designated Product in conjunction with the appropriate TIMERx
                Trademark(s), and as provided below in this Section, and in
                association, if Sanofi so desires in any country of the
                Territory, with a Sanofi Trademark.

                5.2.1   Sanofi acknowledges that all TIMERx Trademarks and all
                        rights therein or registrations thereof, worldwide,
                        shall belong exclusively to TIMERx Technologies, and
                        TIMERx Technologies shall use all reasonable efforts to
                        obtain and maintain registrations for the TIMERx
                        Trademarks in the countries of the Territory. All use of
                        the TIMERx Trademarks as contemplated in this Agreement
                        by Sanofi shall accrue to the benefit of TIMERx
                        Technologies. Sanofi shall make no use of any of the
                        TIMERx Trademarks except to identify and promote the
                        Designated Product as contemplated hereunder for sale in
                        the Territory. Sanofi shall not continue using the
                        TIMERx Trademarks after

                        termination or expiration of this Agreement, nor after
                        the removal or alteration of any such TIMERx Trademark
                        from Exhibit , except to complete sale of reasonable
                        quantities of inventory of the Designated Product on
                        hand at the time of termination or expiration, or at the
                        time of such removal or alteration.

                5.2.2   Sanofi shall cooperate with TIMERx Technologies, at
                        TIMERx Technologies' request and at TIMERx Technologies'
                        expense, to protect the interest of TIMERx Technologies
                        in the TIMERx Trademarks, and shall neither attempt to
                        register nor authorize others to register the TIMERx
                        Trademarks without the prior written consent of TIMERx
                        Technologies in each instance. Sanofi shall promptly
                        inform TIMERx Technologies of any actual or apparent
                        infringement of any TIMERx Trademarks or other
                        intellectual properties of TIMERx Technologies which may
                        come to Sanofi's attention during the term hereof.

                5.2.3   Sanofi shall use all appropriate notices of trademark
                        status of the TIMERx Trademarks, including the "TM"
                        designation (or the (R) symbol for registered marks), in
                        all labeling and promotional materials and shall
                        otherwise conform with all policies and notices of
                        TIMERx Technologies' rights in the marks and for the
                        protection of the TIMERx Trademarks, including without
                        limitation the inclusion of an appropriate footnote
                        acknowledging the use of the TIMERx Trademark(s) under
                        license.

                5.2.4   Samples of the Designated Product and any advertising,
                        promotional materials or packaging related thereto shall
                        be provided by Sanofi to TIMERx Technologies at least
                        thirty days prior to the first use or sale thereof, and
                        at other times upon the reasonable written request of
                        TIMERx Technologies. Sanofi shall use its reasonable
                        commercial endeavours to present drafts (or their
                        equivalents) of such items for the written approval of
                        TIMERx Technologies, which approval shall not be
                        unreasonably withheld, prior to the initial use thereof
                        (or, where this is not possible prior to such initial
                        use, then as soon as possible thereafter). So long as
                        the TIMERx Trademark is registered in the Territory,
                        TIMERx Technologies shall have the right to enter into
                        Sanofi's facilities up to once a year at times agreed by
                        the parties and/or to take other appropriate methods to
                        check the quality of the Designated Product manufactured
                        or offered by Sanofi, from time to time during the term
                        of this Agreement after reasonable prior notice to
                        Sanofi. If at any time or times TIMERx Technologies
                        determines that the quality of the Designated Product
                        manufactured or offered by Sanofi, or the packaging or

                        TIMERx Technologies standards as communicated from time
                        to time to Sanofi, TIMERx Technologies, at its option
                        (and as its only remedy as to trademark matters), shall
                        have the right to suspend or prohibit the use of the
                        TIMERx Trademark(s), provided that TIMERx Technologies
                        has given Sanofi a written notice thereof and a period
                        of 60 days to bring them up to TIMERx Technologies'
                        standards; provided further, however, that TIMERx
                        Technologies need not give such opportunity to cure any
                        deficiency that has been the subject of more than two
                        such notices on prior occasions during the preceding
                        twelve months.

        5.3.    Except for sales to Sanofi or its Affiliates hereunder, and
                subject also to the provisions of Section 7.3, TIMERx
                Technologies agrees that it shall not directly or indirectly,
                during the Exclusivity Period for any country in the Territory,
                sell or market the Designated Products or the Formulated TIMERx
                (for use in the Designated Product) in such country or knowingly
                for export into such country, provided that Sanofi understands
                that TIMERx Technologies may not have effective means to control
                where the Designated Products or Formulated TIMERx are
                ultimately sold or used after being sold by TIMERx Technologies
                or its licensees; provided, however, that nothing herein shall,
                without any objectively justified reason, require TIMERx
                Technologies (i) to refuse to meet unsolicited orders from users
                or resellers outside the Territory who would market the
                Designated Products or Formulated TIMERx within the Territory or
                (ii) to make it difficult for users or resellers to obtain the
                Designated Products or Formulated TIMERx in accordance with
                applicable law from other resellers within the European Union,
                or in particular to prevent users or resellers from obtaining
                outside or from putting on the market in the Territory
                Designated Products or Formulated TIMERx which have been
                lawfully put on the market within the European Union by TIMERx
                Technologies, or with its consent.

        5.4     Subject to Section 7.3, Sanofi shall have no right to sell the
                Designated Products directly or indirectly in or knowingly for
                export to any area other than the Territory, and Sanofi hereby
                agrees that neither it nor its Affiliates shall do so or attempt
                to do so, whether directly or indirectly, provided that TIMERx
                Technologies understands that Sanofi may not have effective
                control over where the Designated Products are ultimately sold
                or used after being sold by Sanofi or its Affiliates; provided,
                however, that nothing herein shall, without any objectively
                justified reason, require Sanofi or its Affiliates (i) to refuse
                to meet unsolicited orders from users or resellers in the
                Territory who would market the Designated Products within that
                part of the European Union outside of the Territory or (ii) to
                make it difficult for users or resellers to obtain the

                Designated Products in accordance with applicable law from other
                resellers within the European Union, or in particular to prevent
                users or resellers from obtaining outside or from putting on the
                market in the Territory Designated Products which have been
                lawfully put on the market within the European Union by TIMERx
                Technologies, or with its consent.

        5.5     In consideration of TIMERx Technologies' entering this Agreement
                and of the grant of the licenses by TIMERx Technologies
                hereunder, Sanofi hereby agrees to pay to TIMERx Technologies
                Royalties equal to ********************************************

                ************************************************.


        5.6     All Royalties payable pursuant to this Agreement shall be due
                quarterly within 60 days following the end of each calendar
                quarter for Net Sales in such calendar quarter. Each such
                payment of Royalties shall be accompanied by a statement of Net
                Sales for the quarter and the calculation of Royalties payable
                hereunder, including an itemization of the quantities of the two
                dosage strengths sold. All Royalties and all other amounts
                payable under this Agreement will bear interest at the rate of 1
                1/2% per month or the maximum legal rate, whichever is less,
                from the date due through the date of payment. Sanofi shall keep
                and shall cause its Affiliates to keep complete, true and
                accurate records for the purpose of showing the derivation of
                all Royalties payable to TIMERx Technologies under this
                Agreement. TIMERx Technologies shall have the right to have such
                records inspected, copied and audited no more than one a year by
                an independent expert during reasonable business hours upon
                reasonable prior written notice to Sanofi or any of its
                Affiliates, respectively. Any such audit shall be at the expense
                of TIMERx Technologies, unless the audit reveals that, with
                respect to the period under audit, less than 97% of the
                Royalties due to TIMERx Technologies hereunder have been paid,
                in which event Sanofi shall pay or reimburse TIMERx Technologies
                for the reasonable expenses of such audit, in addition to TIMERx
                Technologies' other remedies for such underpayment. The parties
                shall reasonably agree from time to time as to whether Royalties
                and other amounts payable under this Agreement shall be
                collected on a local or centralised basis, provided that the
                basis of collection will not reduce the net amounts ultimately
                realized by TIMERx Technologies.

        5.7     All monies due to TIMERx Technologies under this Agreement shall
                be paid in United States Dollars to TIMERx Technologies in

6.      SUPPLY OF FORMULATED TIMERx.

        6.1.    It is understood and agreed that an established source of supply
                of the Formulated TIMERx for use in the Designated Product in
                accordance with the Specifications will be required for
                technically satisfactory exploitation of the rights granted
                hereunder. Accordingly, except as provided in Section 6.2, and
                subject to the other provisions hereof, TIMERx Technologies will
                supply Sanofi and its Affiliates with quantities of Formulated
                TIMERx sufficient to meet their reasonable requirements thereof
                during the Marketing Period, and Sanofi shall purchase all of
                its and its Affiliates' requirements for TIMERx from TIMERx
                Technologies during such period. The price for each kilogram of
                Formulated TIMERx sold hereunder shall equal the applicable Per-
                Kilogram Price multiplied by the kilograms purchased.
                ************************************************************
                **********. If at any time during the term of this Agreement the
                value of the French franc depreciates by more than **********
                during period of at ********** in comparison to the exchange
                rate fixed at the Effective Date, TIMERx Technologies may review
                accordingly the price at which the Formulated TIMERx is supplied
                to Sanofi.

        6.2     If TIMERx Technologies, for reasons of force majeure, fails or
                is unable to supply Sanofi with its and its Affiliates'
                requirements of Formulated TIMERx during the Marketing Period
                pursuant to Section 6.1, TIMERx Technologies shall grant Sanofi
                a nonexclusive license to manufacture Formulated TIMERx under
                the TIMERx Production Technology, and shall make knowledgeable
                personnel available at the expense of TIMERx Technologies (up to
                a maximum of ******) to consult with Sanofi, all to the extent
                necessary to enable Sanofi to produce Formulated TIMERx (from
                the appropriate raw materials) that would otherwise have been
                supplied by TIMERx Technologies or an alternate supplier
                hereunder for Sanofi and its Affiliates in connection with the
                production of the Designated Product pursuant to this Agreement.
                TIMERx Technologies will provide as much prior notice to Sanofi
                of any failure described in this section as the circumstances
                permit. In such event Sanofi shall pay to TIMERx Technologies,
                in addition to the Royalties under Section 5.5,****** of
                Formulated TIMERx produced, converted to Designated Product and
                sold by Sanofi hereunder, *************************************.

        6.3     The following provisions shall be applicable to the situation
                described in Section 6.2:

                6.3.1   Sanofi shall maintain all information and technology
                        delivered to Sanofi pursuant to such Section, whether
                        orally or in writing, in strictest confidence and shall
                        use such information and technology only for the purpose
                        of producing the Formulated TIMERx for its own use and
                        the use of its Affiliates and permitted sublicensees (if
                        any) in connection with this Agreement.

                6.3.2   Sanofi acknowledges that, in doing the foregoing, TIMERx
                        Technologies will not be providing a "turnkey"
                        operation. Rather, TIMERx Technologies will only be
                        required to make available to Sanofi the best standard
                        of knowledge and information then available to TIMERx
                        Technologies and directly used in its or its Affiliate's
                        or licensee's manufacture of the Formulated TIMERx.
                        TIMERx Technologies will not be required to prepare,
                        provide or obtain any information not then in its
                        possession, nor to adapt any of the knowledge or
                        information provided to the particular plant or
                        manufacturing location of Sanofi, including without
                        limitation any local legal, licensing, or environmental
                        considerations. If any professional licenses, visas, or
                        other permits are required for any of the consulting to
                        be provided by TIMERx Technologies' or its Affiliates'
                        or licensees' personnel, Sanofi shall so inform TIMERx
                        Technologies and Sanofi shall bear the costs of
                        obtaining the same.

                6.3.3.  Without prejudice to TIMERx Technologies' obligations
                        under this Agreement, neither TIMERx Technologies nor
                        its Affiliates or licensees will be responsible for any
                        failure of Sanofi or its personnel to understand or
                        properly to implement such knowledge and information or
                        for any materials made by any party other than TIMERx
                        Technologies or such respective Affiliate or licensee
                        using such knowledge and information, except where such
                        failure to understand results from the negligence or
                        willful misconduct of TIMERx Technologies.

                6.3.4.  If TIMERx Technologies' non-delivery of the Formulated
                        TIMERx as described in Section 6.2 resulted in whole or
                        in part from a temporary inability to produce and
                        deliver the same, and TIMERx Technologies gives

                        will again be able and willing to supply the Formulated

                        unreasonably), resume the supply of the Formulated

                        Sanofi will be entitled to exhaust its work in process
                        and any inventory of Formulated TIMERx ****************

        6.4     All sales of Formulated TIMERx hereunder shall be F.O.B.
                Patterson, N.Y., and Sanofi shall bear all transportation,
                insurance, taxes, duties, and other costs and risks of loss,
                spoilage and damage associated with shipping and delivery to
                Sanofi or its Affiliates. All payments by Sanofi to TIMERx
                Technologies pursuant to this Section 6 will be made in US
                dollars within thirty (30) days of receipt by Sanofi of TIMERx
                Technologies' invoice, by direct bank transfer to such account
                of TIMERx Technologies as TIMERx Technologies shall from time to
                time notify Sanofi.

        6.5     TIMERx Technologies shall perform routine quality control tests
                with respect to all Formulated TIMERx as required by the
                applicable Regulatory Authority and any additional quality
                control tests as TIMERx Technologies deems necessary in
                accordance with its applicable policies. No other or special
                tests by TIMERx Technologies will be required, unless and to the
                extent that Sanofi establishes that the same are required in
                order to obtain or maintain a Regulatory Authority or other
                governmental license to market the Designated Product in the
                Territory. The parties will reasonably and timely agree in a
                separate quality control agreement upon quality control, quality
                assurance, and inspection testing procedures and
                responsibilities as required by applicable regulations.

        6.6     If Sanofi considers any such shipment not to conform to the
                applicable Specifications for the Formulated TIMERx, Sanofi
                shall notify TIMERx Technologies in accordance with the quality
                control agreement referenced in Section 6.5 and provide TIMERx
                Technologies with the relevant analysis. TIMERx TECHNOLOGIES'
                SOLE OBLIGATION AND SANOFI'S EXCLUSIVE REMEDY FOR ANY SUCH
                NONCONFORMITY THAT IS EITHER DETECTED, OR THAT WOULD HAVE BEEN
                DETECTABLE THROUGH PROPER APPLICATION OF THE STANDARD QUALITY
                CONTROL PROCEDURES IN THE INDUSTRY, SHALL BE AS FOLLOWS:

                                accept return, or cause its supplier to accept
                                return, of any shipment not accepted, or else

                                destruction; and

                        ii)     TIMERx Technologies shall replace the

        6.7     While TIMERx Technologies is supplying Formulated TIMERx
                hereunder to Sanofi, TIMERx Technologies shall, after receipt of
                reasonable prior notice, give duly accredited representatives of
                Sanofi access at all reasonable times during regular business
                hours to TIMERx Technologies' or its Affiliate's plant in which
                the Formulated TIMERx is being produced, and (if and to the
                extent Sanofi establishes that it must have such access in order
                to obtain or maintain a Regulatory Authority or other
                governmental license to market the Designated Product) to the
                plant of any licensee in which the Formulated TIMERx is being
                produced, in up to two visits per year. In addition, TIMERx
                Technologies will use all its reasonable efforts to obtain the
                permission of any such licensee for other access to such
                licensee's plant as may be reasonably requested by Sanofi.

        6.8     Sanofi shall, within three months following the filing by Sanofi
                of each PLA with each Regulatory Authority for the Designated
                Product, submit to TIMERx Technologies Sanofi's best estimate of
                its requirements for Formulated TIMERx in the six month period
                following the later of the Approval Date or the Other
                Governmental Approval Date in the applicable country, which
                estimates will be subject to firm order pursuant to Section 6.9.

        6.9     Sanofi shall deliver to TIMERx Technologies a firm written order
                stating its (and/or its Affiliates') requirements for Formulated
                TIMERx to be used for production of the Designated Product for
                commercial use or sale no less than **** in advance of the
                requested delivery date therefor. All such firm orders shall be
                non-cancellable by Sanofi. TIMERx Technologies will supply
                quantities within **** following receipt of Sanofi's firm
                written order therefor. TIMERx Technologies shall have no
                obligation to supply Sanofi with quantities during any quarter
                in excess of **** of the highest quantity estimated in Sanofi's
                estimates for that quarter pursuant to Section 6.10. TIMERx
                Technologies, will supply to Sanofi an inventory of ****
                production requirements of Formulated TIMERx for Sanofi and its
                Affiliates, based on Sanofi's projections given under Section
                6.10 for the **** extending beyond the **** firm ordering period
                (but not in excess of **** of Sanofi's actual firm order volume
                for such firm order period). TIMERx Technologies will bear the
                costs of this **** inventory of Formulated TIMERx to be held by
                Sanofi at its own storage facilities (at Sanofi's costs and risk
                as to storage), by not invoicing Sanofi for the price of such
                inventory (unless and until the inventory is finally depleted).

        6.10    At least **** before Sanofi and/or its Affiliates begin
                commercial sale of the Designated Product, Sanofi shall deliver
                to TIMERx Technologies a written, non-binding estimate of all
                requirements of Formulated TIMERx

                during the following ****. Sanofi will deliver to TIMERx
                Technologies updates to such estimates on or before the first
                day of each January, April, July and October thereafter, which
                updates may revise estimates previously submitted, and will add
                estimates for additional months so that each such estimate
                covers the **** period following the end of the firm-order
                period (that is, the **** after the month in which such
                estimates are made), it being understood, however, that as to
                ****, Sanofi may give such estimates on an aggregated quarterly
                or semi-annual basis.

        6.11    Pursuant to the terms of Exhibit 6.11, each party shall promptly
                notify the other of any fact, circumstance, condition or
                knowledge dealing with TIMERx or the Designated Product of which
                the Party becomes aware that bears upon the safety or efficacy
                of TIMERx or the Designated Product or as to any adverse drug
                reaction (whether or not due to a defect in the Designated
                Product or the Formulated TIMERx). Each party shall immediately
                notify the other of any inspection or audit relating to TIMERx,
                Formulated TIMERx, or the Designated Product by any governmental
                regulatory authority in the Territory. If a representative of
                the governmental authority takes samples in connection with such
                audit or inspection, the parties shall immediately provide each
                other, as appropriate, with samples from the same batch. The
                party in receipt of such notice will provide the other party
                within 72 hours, with copies of all relevant documents, warning
                letters and other correspondence and notifications as such other
                party may reasonably request. TIMERx Technologies and Sanofi
                agree to cooperate with each other during any inspection,
                investigation or other inquiry by a Regulatory Authority or
                other governmental entity, including providing information
                and/or documentation, as requested by the Regulatory Authority,
                or other governmental entity. To the extent permissible, TIMERx
                Technologies and Sanofi also agree to discuss any responses to
                observations or notifications received and to give the other
                party an opportunity to comment on any proposed response before
                it is made. In the event of disagreement concerning the content
                or form of such response, Sanofi shall be responsible for
                deciding the appropriate form and content of any response with
                respect to any of its cited activities and TIMERx Technologies
                shall be responsible for deciding the appropriate form and
                content of any response with respect to any of its cited
                activities. Each party shall inform the other of all comments
                and conclusions received from the governmental authority.

7.      OWNERSHIP AND OTHER LICENSES.

        7.1.    Except as otherwise explicitly licensed or transferred as
                provided herein, each party will, as between it and the other
                party hereto, retain

                ownership of any and all inventions, copyrights, trade marks,
                trade secrets, patent rights and other technology and rights to
                the extent conceived or developed by its personnel or
                contractors (other than the other party hereto) pursuant to this
                Agreement. Neither party makes any grant of rights by
                implication. TIMERx Technologies will retain ownership in (but
                Sanofi shall have the right to use within the scope of its
                licenses) the Phase I Dissolution Profile Studies and Sanofi
                will retain ownership (but TIMERx Technologies shall have the
                right to use within the scope of, and as limited by, its
                licenses thereto under Section 7.8) Sanofi Test and Regulatory
                Data and its PLAs.

        7.2     Except as otherwise provided herein, each party shall be
                responsible, as it shall determine, for the filing and
                prosecution of any and all patent applications with respect, in
                whole or in part, to its own intellectual property and for the
                maintenance of any available patent protection with respect
                thereto; provided however, that neither party commits that any
                such patent protection will be available or continuous
                hereunder, but TIMERx Technologies shall exert, as to the
                Territory, all reasonable efforts to secure and to maintain in
                force patent protection under the Principal Patents.

        7.3     Notwithstanding Section 2.1, Sanofi understands and agrees that
                TIMERx Technologies and/or its other licensee(s) may, during the
                Exclusivity Period, supply the Designated Product within any
                country in the Territory, so long as it does so following the
                fifth anniversary of the first time the Designated Product is
                put on the market anywhere in the European Union and in response
                to unsolicited orders and does not pursue an active policy of
                putting the Designated Product on the market in such
                country(ies) during the Exclusivity Period. Similarly, Sanofi
                will have the right to supply the Designated Product within any
                country in the European Union that is not part of the Territory,
                so long as it does so in response to unsolicited orders and does
                not pursue an active policy of putting the Designated Product on
                the market in such country(ies), and so long as it does so
                following such fifth anniversary with respect to any areas in
                which TIMERx Technologies has at any time granted another entity
                distribution rights with respect to the Designated Product.

        7.4     Sanofi acknowledges that TIMERx Technologies, for itself and for
                others, applies, and will seek to apply, TIMERx to products
                other than the Designated Product. No provision hereof, and no
                exclusivity hereunder, shall prevent TIMERx Technologies from so
                applying TIMERx or Formulated TIMERx, so long as the end product
                is not the Designated Product in the Territory hereunder.

        7.5     Sanofi hereby grants to TIMERx Technologies a nonexclusive,
                paid-up

                to make, have made, use and sell Formulated TIMERx during the
                License Term, if and to the extent such license is necessary for
                TIMERx Technologies to do so as agreed hereunder, for the
                purposes of manufacturing, having manufactured and supplying the
                Formulated TIMERx to Sanofi hereunder, including without
                limitation any and all Sanofi Test and Regulatory Data.

        7.6     Subject to and conditional upon the failure or continuing
                inability of TIMERx Technologies to meet Sanofi's and its
                Affiliates' requirements for Formulated TIMERx for reasons of
                force majeure as provided in Section 6.2, TIMERx Technologies
                grants to Sanofi a nonexclusive license under the TIMERx
                Production Technology to make and have made the Formulated
                TIMERx during the License Term (subject to Section 6.3.4) solely
                for use in manufacturing the Designated Product as permitted
                hereunder. Sanofi shall have no right to grant sublicenses of
                its rights hereunder except to an Affiliate of Sanofi without
                the prior written consent of TIMERx Technologies, in its
                discretion.

        7.7     Sanofi hereby grants to TIMERx Technologies a nonexclusive,
                paid-up, worldwide license, with right to sublicense, under any
                and all Sanofi Improvements and any and all patents, patent
                applications, trade secrets, copyrights, and other intellectual
                property rights of any sort covering the Sanofi Improvements, to
                make, have made, use and sell any products or services using or
                based upon TIMERx or related technology, other than the
                Designated Product in the Territory during the License Term.
                Sanofi will, throughout the License Term, promptly notify TIMERx
                Technologies of all Sanofi Improvements and provide TIMERx
                Technologies with access to all of the same, solely for use
                within the scope of the license stated in this section; provided
                that the exercise of any patents covering any Sanofi
                Improvements shall, except as stated in Section 7.5, require the
                payment to Sanofi of a reasonable fee or royalty.

        7.8     Sanofi hereby grants TIMERx Technologies a nonexclusive, paid-up
                (except as noted below in this section) license, with right to
                sublicense, under all rights of Sanofi and its Affiliates in and
                to the Sanofi Test and Regulatory Data to use the same for

                Designated Product for marketing or use in a country in the
                Territory during the Exclusivity Period in such country. Such
                licensed use of Sanofi Clinical Data shall require prior notice
                to Sanofi and its consent thereto, which consent shall not be
                unreasonably withheld or delayed, and such license shall also

                Clinical Data is used under this license; provided, however that
                no such fee shall be payable if the only use of the Sanofi
                Clinical Data is in connection with attempts to secure
                regulatory approval for the Designated Product in a country or
                countries which were once in the Territory but as to which
                Sanofi has, for any reason, abandoned its efforts to secure such
                approval. Sanofi hereby agrees to make the Sanofi Test and
                Regulatory Data available to TIMERx Technologies which may in
                turn make the same available to sublicensees for use by them in
                respect of any Abbreviated New Drug Application ("ANDA"), New
                Drug Application ("NDA"), PLA, or other governmental filings
                made by them within the scope of such license. The license under
                this section shall survive any termination or expiration of the
                term of this Agreement, except a termination under Section 11.4
                due to an uncured breach by TIMERx Technologies. Sanofi will,
                throughout the License Term and solely for use within the scope
                of the license stated in this section, provide to TIMERx
                Technologies on request access to all of the Sanofi Test and
                Regulatory Data in or coming into Sanofi's possession or
                otherwise reasonably available to it.

        7.9     Each party agrees to mark and to have marked by its sublicensees
                every product manufactured, used or sold by it or its
                sublicensees in accordance with applicable laws relating to the
                marking of patented articles with notices of patent.

8.      CONFIDENTIALITY.

        8.1.    In the course of performance under this Agreement or during the
                discussions leading thereto, a party may disclose, or may have
                disclosed, in writing, orally or by demonstration or sample, to
                the other party confidential information belonging to such party
                or entrusted to it by a supplier or licensee, which information
                is marked or stated in writing at or within 30 days after its
                disclosure to be "confidential" or "trade secret" information.
                All such confidential information disclosed by a party shall be
                maintained in confidence by the other and will not be used by
                the other party for any purpose except as authorized hereunder.
                Each party shall exercise, and shall cause its Affiliates,
                sublicensees, and consultants to exercise, a reasonable degree
                of care and at least the same degree of care as it uses to
                protect its own confidential information of similar nature to
                preserve the confidentiality of such information disclosed by
                the other party. Each party shall safeguard such information
                against disclosure to third parties, including without
                limitation employees and persons working or consulting for such
                party that do not have an established, current need to know such
                information for purposes authorized under this Agreement. This
                obligation of confidentiality does

                not apply to information and material:

                8.1.1.  that were properly in the possession of the receiving
                        party, without any restriction on use or disclosure,
                        prior to receipt from the other party, each party
                        acknowledging that the other very likely already has
                        information that is relevant to this Agreement;

                8.1.2.  that are at the time of disclosure hereunder in the
                        public domain by public use, publication, or general
                        knowledge;

                8.1.3.  that become general or public knowledge through no fault
                        of the receiving party or its Affiliates following
                        disclosure hereunder;

                8.1.4.  that are properly obtained by the receiving party from a
                        third party not under a confidentiality obligation to
                        the disclosing party hereto; or

                8.1.5.  to the extent the same are required to be disclosed by
                        order of any court or governmental authority; provided,
                        however, that the receiving party shall use its best
                        efforts to give the disclosing party prior notice of any
                        such disclosure so as to afford the disclosing party a
                        reasonable opportunity to seek, at the expense of the
                        disclosing party, such protective orders or other relief
                        as may be available in the circumstances.

        8.2     Neither party shall make any public announcement or other
                publication regarding this Agreement (whether as to the
                existence or terms hereof) or the development work or project
                hereunder or the results thereof without the prior, written
                consent of the other party, which consent shall not be
                unreasonably withheld; provided that the foregoing shall not
                prohibit any disclosure which, in the opinion of counsel to the
                disclosing party, is required by any applicable law or by any
                competent governmental authority. In no event shall either party
                make any disclosure of any such results before a patent
                application has been filed with respect thereto, except upon the
                prior written approval of the other party.

9.      INFRINGEMENT.

        9.1.    TIMERx Technologies shall exert all reasonable efforts to
                monitor and to attempt to stop any infringements by third
                parties of any patent included within the Principal Patents and
                shall promptly inform Sanofi of any such suspected infringements
                or of any of the other TIMERx






                                       25
   26


                Technologies Patents or the infringement or misappropriation of
                the Product Production Technology or the TIMERx Production
                Technology by a third party of which it becomes aware, to the
                extent such infringement involves the manufacture, use or sale
                of the Designated Product in a country in the Territory during
                the Exclusivity Period for such country ("Covered
                Infringement"). Sanofi shall exert reasonable efforts to monitor
                the marketplace and shall promptly inform TIMERx Technologies of
                any suspected infringement of any of the TIMERx Technologies
                Patents or infringement or misappropriation of the Product
                Production Technology or the TIMERx Production Technology of
                which it becomes aware, whether or not the same involves a
                Covered Infringement.

        9.2     If the suspected infringement or misappropriation does not
                involve a Covered Infringement, TIMERx Technologies may take, or
                refrain from taking, any action it chooses, with or without
                notice to Sanofi, and Sanofi shall have no right to take any
                action with respect to such suspected infringement or
                misappropriation, nor to any recoveries with respect thereto. If
                the suspected infringement or misappropriation involves a
                Covered Infringement, TIMERx Technologies shall, within 120 days
                of the first notice referred to in Section 9.1, inform Sanofi
                whether or not TIMERx Technologies intends to institute suit
                against such third party with respect to a Covered Infringement,
                it being understood that any failure of TIMERx Technologies to
                bring any such suit shall only lead to the consequences stated
                in Section 9.7 if such failure is a breach of TIMERx
                Technologies' duty of reasonable efforts stated in Section 9.1.
                Sanofi will not take any steps toward instituting suit against
                any third party involving a Covered Infringement until TIMERx
                Technologies has informed Sanofi of its intention pursuant to
                the previous sentence.

        9.3     TIMERx Technologies shall notify Sanofi of any suit that it
                institutes against a third party with respect to a Covered
                Infringement. If Sanofi does not agree to join in such suit as
                provided in Section 9.4, TIMERx Technologies may bring such suit
                on its own and shall in such event bear all costs of, and shall
                exercise all control over, such suit. TIMERx Technologies may,
                at its expense, bring such action in the name of Sanofi and/or
                cause Sanofi to be joined in the suit as a plaintiff.
                Recoveries, if any, whether by judgment, award, decree or
                settlement, shall belong solely to TIMERx Technologies.

        9.4     If TIMERx Technologies notifies Sanofi that it intends to
                institute suit against such third party with respect to a
                Covered Infringement together with a description of all of the
                material information available to TIMERx Technologies with
                respect thereto, and Sanofi notifies TIMERx Technologies within
                30 days after receipt of such notice and description

                that Sanofi desires to institute suit jointly, the suit shall be
                brought jointly in the names of both parties and all costs
                thereof shall be borne equally. Recoveries, if any, whether by
                judgment, award, decree or settlement, shall, after the
                reimbursement of each of TIMERx Technologies and Sanofi for its
                share of the joint costs in such action, be shared between
                TIMERx Technologies and Sanofi equally.

        9.5     If TIMERx Technologies notifies Sanofi that it does not intend
                to institute suit against such third party with respect to a
                Covered Infringement, Sanofi may institute suit on its own.

                in connection with such suit. Otherwise, Sanofi may ****** as
                such reimbursements. Recoveries, if any, whether by judgment,
                award, decree or settlement covered by this section, shall
                belong solely to Sanofi.

        9.6     Should either TIMERx Technologies or Sanofi commence a suit
                under the provisions of this Section 9 and thereafter elect to
                abandon the same, it shall give timely notice to the other
                party, who may, if it so desires, be joined as a plaintiff in
                the suit (or continue as such if it is already one) and continue
                prosecution of such suit, provided, however, that the sharing of
                expenses and any recovery of such suit shall be as agreed upon
                between TIMERx Technologies and Sanofi.

        9.7     In no event shall Sanofi's monetary remedies for any breaches or
                deficiencies in TIMERx Technologies' performance of its
                obligations under this Section 9 or under Section 7.2,
                regardless of the number or severity thereof, exceed the rebate
                of one-third of the Royalties that would otherwise be due to
                TIMERx Technologies under Section 5.5 with respect to Net Sales
                made in or to the country or countries to which such breaches or
                deficiencies relate, unless such breaches or deficiencies lead
                to a result described in Exhibit 5.5 , in which case that
                Exhibit shall apply as stated in Section 5.5.

10.     REPRESENTATIONS, WARRANTIES AND INDEMNITIES.

        10.1.   Each party represents and warrants to the other that, to the
                best of its current knowledge, it has the full right and

                        10.2 or 10.3.1;

                10.9.3. a breach of TIMERx Technologies' warranty under Section
                        10.6, except as otherwise provided in Section 6.2, in
                        the circumstances there stated;

                10.9.4. any failure of the Formulated TIMERx manufactured by
                        TIMERx Technologies or its alternate supplier (but not
                        by Sanofi under Section 6.2), as delivered to Sanofi
                        hereunder to conform to the applicable Specifications or
                        the negligent or defective manufacture by TIMERx
                        Technologies of the Formulated TIMERx; or

                10.9.5  any failure of TIMERx Technologies to comply with its
                        obligation under Section 6.11 to notify Sanofi of any
                        information coming into TIMERx Technologies' possession
                        and bearing on the safety of TIMERx or the Designated
                        Product, and not arising from any other aspect of the
                        Designated Product or its formulation, development,
                        supply, production, manufacture, sale, delivery,
                        distribution or use, nor from any act or omission of
                        Sanofi with respect to the Designated Product or with
                        respect to any Formulated TIMERx following its delivery
                        to Sanofi hereunder. TIMERx Technologies shall also
                        indemnify, defend and hold Sanofi and its Affiliates and
                        sublicensees harmless from any and all third-party
                        claims to the extent arising from, in connection with,
                        based upon, by reason of, or relating in any way to a
                        breach of TIMERx Technologies' warranty under Section
                        10.3.2 (subject, however to Section 10.5), provided,
                        however, that if TIMERx Technologies reasonably believes
                        that it may have committed any such breaches, it may at
                        its election terminate the License Term upon thirty (30)
                        days' notice to Sanofi with respect to any Designated
                        Product with respect to sales thereof that could add to
                        the size of its exposure under Section 10.5; provided,
                        however, that if TIMERx Technologies so terminates the
                        License Term under this sentence, Sanofi's remedies will
                        not be limited by Section 10.5 as to claims arising
                        from, in connection with, based upon, by reason of, or
                        relating in any way to, such situation.

        10.10   Sanofi shall indemnify, defend and hold TIMERx Technologies
                harmless from any and all third-party claims to the extent
                arising from, in connection with, based upon, by reason of, or
                relating in any way to: (i) the supply, registration,
                production, manufacture, sale, delivery, distribution or use of
                the Designated Product, except for any matters which are covered
                by TIMERx Technologies' indemnities under Section 10.9; (ii) a
                breach of Sanofi's warranty under Section 10.1; or (iii) any





                                       30
   31


                                                                           
                failure of Sanofi to comply with its obligation under Section
                6.11 to notify TIMERx Technologies of any information coming
                into Sanofi's possession and bearing on the safety of TIMERx or
                the Designated Product.

        10.11   Notwithstanding anything to the contrary set forth elsewhere
                herein, neither Sanofi nor TIMERx Technologies shall be
                obligated to indemnify the other party for claims or liabilities
                to the extent arising from such other party's negligence,
                intentional misconduct, or breach of its duties, obligations,
                warranties or representations set forth herein or those of its
                Affiliates, sublicensees or assigns.

        10.12   Whenever indemnification is provided for a party under this
                Agreement, such right of indemnification shall extend also to
                the indemnified party's Affiliates, officers, directors,
                shareholders, successors, assigns, agents, employees, and
                insurers to the extent the same become subject to such claim in
                such capacity. The party seeking indemnification shall provide
                the indemnifying party with written notice of any claim or
                action within ten (10) days of its receipt thereof, and shall
                afford the indemnifying party the right to control the defense
                and settlement of such claim or action. The party seeking
                indemnification shall provide reasonable assistance to the
                indemnifying party in the defense of such claim or action. If
                the defendants in any such action include both Sanofi and TIMERx
                Technologies and either party concludes that there may be legal
                defenses available to it which are different from, additional
                to, or inconsistent with, those available to the other, that
                party shall have the right to select separate counsel to
                participate in the defense of such action on its behalf, and
                such party shall thereafter bear the cost and expense of such
                separate defense. Should the indemnifying party determine not to
                defend such claim or action, the other party shall have the
                right to maintain the defense of such claim or action and the
                indemnifying party agrees to provide reasonable assistance to it
                in the defense of such claim or action. Neither party shall
                settle any such claim or action in a way that prejudices or
                adversely impacts the other party to this Agreement without the
                prior approval of such other party (which approval shall not be
                unreasonably withheld).

        10.13   NOTWITHSTANDING ANYTHING TO THE CONTRARY CONTAINED IN THIS
                AGREEMENT (OTHER THAN SECTION 8, SECTION 9.7, SECTION 10.5,
                SECTION 10.9, AND SECTION 10.10), NEITHER PARTY SHALL UNDER ANY
                CIRCUMSTANCES BE LIABLE FOR CLAIMS FOR ANY INCIDENTAL,
                CONSEQUENTIAL, INDIRECT OR SPECIAL DAMAGES, INCLUDING ANY LOST
                PROFITS OR SAVINGS, ARISING FROM ANY BREACH OF WARRANTY OR THE
                PERFORMANCE OR BREACH OF ANY PROVISION OF THIS

                AGREEMENT OR THE USE OR INABILITY TO USE TIMERx, THE DESIGNATED
                PRODUCT, TIMERx TECHNOLOGIES PATENTS, TIMERx TECHNOLOGIES'
                CONFIDENTIAL TECHNOLOGY, PRODUCT PRODUCTION TECHNOLOGY, TIMERx
                PRODUCTION TECHNOLOGY, TIMERx TECHNOLOGIES TEST AND REGULATORY
                DATA, SANOFI IMPROVEMENTS, OR SANOFI TEST AND REGULATORY DATA.

11.     TERM AND TERMINATION.

        11.1    The term of this Agreement shall begin on the date set forth
                above and shall, unless earlier terminated as provided herein,
                continue until the end of the License Term.

        11.2    TIMERx Technologies may at its option transform the Exclusivity
                Period in a country (or group of countries, as so designated in
                Exhibit 11.2) into a period for the balance of the License Term,
                in which Sanofi's rights will be nonexclusive, if Sanofi fails
                to sell at least the minimum sales volumes stated in Exhibit
                11.2 in such country or group (as indicated in Exhibit 11.2),
                for any of the periods stated. Such option shall be exercised by
                TIMERx Technologies, if at all, by written notice to Sanofi
                given during the 120 days following TIMERx Technologies' receipt
                of Sanofi's report of sales indicating that any such minimum
                sales volume was not met during the applicable period.

        11.3    If Sanofi fails to meet at least ***** of the minimum sales
                volumes specified in Exhibit 11.2 with respect to any country or
                group of countries (as indicated in Exhibit 11.2) for any of the
                periods stated in such Exhibit, TIMERx Technologies may at its
                option elect to terminate the Marketing Period and the License
                Term with respect to that country or group upon the delivery of
                written notice to Sanofi, delivered on or prior to the 90th day
                after the later of the end of such period or TIMERx
                Technologies' receipt of a report from Sanofi reporting such
                failure.

        11.4    In the event that either party materially breaches any of the
                terms, conditions or agreements contained in this Agreement to
                be kept, observed or performed by it, then the other party may
                terminate this Agreement, at its option and without prejudice to
                any of its other legal or equitable rights or remedies, by
                giving the party who committed the breach (i) in the case of
                breach of obligations other than the payment of money, 60 days'
                notice in writing, unless the notified party within such 60-day
                period shall have cured the breach, and (ii) in the case of
                breach of an obligation for the payment of money, 20 days'
                notice in writing, unless the notified party within such 20-day
                period shall have cured the







                                       32
   33


                breach, including any required payment of interest on previously
                unpaid amounts as set forth herein.

        11.5    This Agreement will automatically terminate if either party
                files for protection under applicable bankruptcy laws, becomes
                insolvent, makes an assignment for the benefit of creditors,
                appoints or suffers appointment of a receiver or trustee over
                its property, files a petition under any bankruptcy or
                insolvency act or has such petition filed against it.

        11.6    Any sublicenses granted by Sanofi under this Agreement shall
                provide for termination or assignment to TIMERx Technologies, at
                the option of TIMERx Technologies, of Sanofi's interest therein
                upon termination of this Agreement.

        11.7    Following any expiration or termination of the License Term, or
                of the Exclusivity Period in any country, the license to TIMERx
                Technologies under Section 7.8 shall be thereafter extended to
                include (in addition to its coverage as stated in such section)
                the use of Sanofi Test and Regulatory Data for purposes of
                complying with governmental requirements with respect to the
                Designated Product for marketing or use in the Territory, or in
                such country as to which the Exclusivity Period has expired or
                terminated.

        11.8    Sanofi's obligations regarding payment of Royalties accrued as
                of the date of termination, TIMERx Technologies' rights under
                Sections 7.7 and 7.8 (except if this Agreement is terminated due
                to an uncured breach on the part of TIMERx Technologies), and
                Sanofi's rights under Section 2.2 (except if this Agreement is
                terminated due to an uncured breach on the part of Sanofi), and
                the provisions of Sections 8, 10, and 12, hereof shall survive
                any expiration or termination of this Agreement.

12.     MISCELLANEOUS.

        12.1.   This Agreement incorporates the Exhibits referenced herein. This
                Agreement constitutes the entire agreement and supersedes all
                prior agreements and understandings, both written and oral,
                between the parties hereto with respect to the subject matter
                hereof.

        12.2    This Agreement shall be binding upon and inure to the benefit of
                the parties hereto and their successors and permitted assigns;
                provided, however, that except as part of the transfer of all or
                substantially all assets (which, as to TIMERx Technologies,
                shall refer to the assets of its division of Penwest, Ltd.) to a
                single buyer or pursuant to a merger or

                other corporate reorganization (other than a sale by either
                party to Bayer or Pfizer or any of their affiliates):

                12.2.1  TIMERx Technologies shall not delegate or subcontract
                        any of its obligations during the Development Period,
                        and

                12.2.2  Sanofi shall not assign or delegate its rights or
                        obligations hereunder at any time, without the prior
                        written consent of the other party hereto.
                        Notwithstanding the foregoing, either party may assign
                        or delegate all or part of its rights and obligations
                        hereunder to its Affiliates without the prior written
                        consent of the other party (but such assignment or
                        delegation shall require that the other party be given
                        notice thereof).

        12.3.   All notices, requests or other communication provided for or
                permitted hereunder shall be given in writing and shall be hand
                delivered or sent by facsimile, reputable courier or by
                registered or certified mail, postage prepaid, return receipt
                requested, to the address set forth on the signature page of
                this Agreement, or to such other address as either party may
                inform the other of in writing. Notices will be deemed delivered
                on the earliest of transmission by facsimile, actual receipt or
                three days after mailing as set forth herein.

        12.4    Any terms of this Agreement may be amended, modified or waived
                only in a writing signed by both parties.

        12.5    If any provision of this Agreement shall be held invalid,
                illegal or unenforceable, such provision shall be enforced to
                the maximum extent permitted by law and the parties' fundamental
                intentions hereunder, and the remaining provisions shall not be
                affected or impaired.

        12.6    Nothing herein contained shall constitute this a joint venture
                agreement or constitute either party as the partner, principal
                or agent of the other, this being an Agreement between
                independent contracting entities. Neither party shall have the
                authority to bind the other in any respect whatsoever. Except as
                provided herein, nothing contained in this Agreement shall be
                construed as conferring any right on either party to use any
                name, trade name, trademark or other designation of the other
                party hereto, unless the express, written permission of such
                other party has been obtained.

        12.7    In the event that either party hereto is prevented from carrying
                out its obligations under this Agreement by events beyond its
                reasonable







                                       34

                control, including without limitation acts of God or government,
                natural disasters or storms, fire, political strife, labor
                disputes, failure or delay of transportation, default by
                suppliers or unavailability of parts, then such party's
                performance of its obligations hereunder shall be excused during
                the period of such event and for a reasonable period of recovery
                thereafter, and the time for performance of such obligations
                shall be automatically extended for a period of time equal to
                the duration of such event or events; provided, however, that
                the other party may, at its election, terminate this Agreement
                upon 120 days' prior notice to the party affected by such
                events, unless such events cease to prevent such affected
                party's performance hereunder during such 120-day period.

        12.8    This Agreement shall be governed by, and construed and enforced
                in accordance with, the laws of England without regard to its
                conflict of laws rules.

        12.9    Any dispute or difference, other than a question relating to
                patent validity, between the parties arising out of or in
                connection with this Agreement shall be resolved by arbitration
                conducted in the English language in London, England before a
                panel of three arbitrators under the administration and
                then-current rules of the London Court of International
                Arbitration, or other rules or administration as the parties may
                agree. The arbitrators shall apply to the merits of the dispute
                or claim the provisions of this Agreement, and in case of
                silence of such provisions, the laws of England. The prevailing
                party in any such proceeding shall be entitled to an award of
                its reasonable attorneys' fees and other costs, including the
                fees and expenses of the arbitrators and the London Court of
                International Arbitration, provided that the same may be
                apportioned between the parties by the arbitrators if they
                determine that each party has prevailed in part. The arbitral
                award shall be binding and conclusive on both parties and may be
                enforced in any court of competent jurisdiction. Notwithstanding
