      Customer at LB's cost with no mark up or premium added. Customer shall pay
      for the Resins prior to the start of the cGMP run. LB shall use the Resins

      remain the property of Customer, and at the Customer's request and option,
      LB shall destroy or return to the Customer all of the Resins at the
      termination of this Agreement.

2.2   Immediately following the date of the Agreement the Customer shall supply
      to LB the Customer Information, together with full details of any hazards
      relating to the Cell Line and/or the Customer Materials, their storage and
      use. On review of this Customer Information, the Cell Line and/or the
      Customer Materials shall be provided to LB at LB's request. Property in
      the Cell Line and/or the Customer Materials and/or the Customer
      Information supplied to LB shall remain vested in the Customer.

2.3   The Customer hereby grants LB the non-exclusive right to use the Cell
      Line, the Customer Materials and the Customer Information only for the

            of the Services;

                                       4

<PAGE>

      2.4.3 To the best of the Customer's knowledge and belief as of the date of
            this Agreement the patents and patent applications and corresponding
            international applications and patents listed on Schedule 4 relating
            to any of the Cell Line, the other Customer Materials, Customer
            Information and Customer Patent Rights not owned by Customer are
            licensed to Customer under a licence which will permit their use by
            LB to perform the Services;

      2.4.4 to the best of Customer's knowledge and belief as of the date of
            this Agreement, the use by LB of the Cell Line, other Customer
            Materials, Customer Information and Customer Patent Rights for the
            Services (including without limitation the manufacture of the
            Product) will not infringe any intellectual property rights of any
            third party other than third parties from whom customer is a
            sublicensee through LB (provided, however, that LB shall waive any
            breach of this warranty which arises if a court of competent
            jurisdiction determines that the use by LB of the Cell Line, other
            Customer Materials, Customer Information or Customer Patent Rights
            for the Services infringes the intellectual property rights of a
            third party, provided that and for so long as Customer actually
            indemnifies LB pursuant to Clauses 2.5 and 2.6); this warranty is
            limited to the Cell Line, other Customer Materials, Customer
            Information and Customer Patent Rights; Customer makes no warranty
            as to the Process or the Services; and

            notified of a claim from a third party that the Cell Line, other
            Customer Materials, Customer Information or the Customer Patent
            Rights or that the use by LB thereof for the provision of the
            Services infringes any intellectual property rights of such third
            party.

Clause 2.4 is in lieu of all conditions, warranties and statements in respect of
the Cell Line, Customer Information, Customer Patent Rights and/or Customer
Materials whether expressed or implied by statute, custom of the trade or
otherwise (including but without limitation any such condition, warranty or
statement relating to the description or quality of the Cell Line, Customer
Patent Rights, Customer Materials and Customer Information, their fitness or
suitability for a particular purpose or use under any conditions whether or not
known to Customer) and any such condition, warranty or statement is hereby
excluded.

2.5   The Customer undertakes to indemnify and to maintain LB promptly
      indemnified against any direct loss, damage, costs and expenses (including
      court costs and legal fees), that LB may suffer arising directly out of
      any breach of the warranties given by the Customer under Clause 2.4 above
      or any claims alleging LB's use of the Cell Line, the Customer Materials
      or the Customer Information infringes any rights (including, without
      limitation, any intellectual or industrial property rights) vested in any
      third party (other than third parties from whom Customer is a sublicense
      through LB) (whether or not the Customer knows or ought to have known
      about the same).

2.6   The Customer shall further indemnify and maintain LB promptly indemnified
      against all claims, actions, costs, expenses (including court costs and
      legal fees on a full indemnity basis) or other liabilities whatsoever in
      respect of:

      2.6.1 any product liability in respect of Product, except to the extent
            such liability is caused by (1) the negligent or willful act or
            omission of LB in the production and/or supply of Product or
            provision of Services, or (2) breach of any warranty by LB, or (3)
            breach of a term of this Agreement by LB; and

      2.6.2 any negligent or willful act or omission of the Customer in relation
            to the use, processing, storage or sale of the Product.

2.7   Customer shall not be liable for the following loss or damage howsoever
caused (even if foreseeable or in the contemplation of LB or the Customer):

                                       5

<PAGE>

      2.7.1 loss of profits, business or revenue whether suffered by LB or any
            other person; or

      2.7.2 special, indirect or consequential loss, whether suffered by LB or
            any other person; and

      2.7.3 any loss arising from any claim made against LB by any other person.

2.8   Customer shall obtain and maintain clinical trial insurance with a
reputable and solvent insurance provider in the amount of five million dollars
per event or linked events. Customer shall supply LB with a copy of such
insurance policy on reasonable request and shall not terminate or amend (other
than amending to increase the level of cover) such policy without prior written
notice to LB.

2.9   The obligations of the Customer under this Clause 2 shall survive the
termination for whatever reason of the Agreement.

3     PROVISION OF THE SERVICES

      3.1.1 LB shall diligently carry out the Services as provided in Schedule
            2, shall initiate the first cGMP run prior to the end of March 2005,
            and shall use all reasonable efforts to achieve the estimated
            timescales and Specifications set out in that Schedule, with the aim
            of ensuring that the Product is accepted by the FDA for use in a
            Phase III clinical trial.

      3.1.2 If due to the negligence or willful misconduct of LB:

            (i)   the Product does not meet the Specification; or

            (ii)  the Product meets the Specification but for other reasons
            cannot be used in a clinical trial;

            then the Customer shall be under no obligation to pay for the cGMP
            batch that produced such Product (in which case LB shall refund
            amounts already paid by Customer in respect of such batch), and
            shall at its discretion have the option of terminating this
            Agreement in accordance with the principles of Clause 8.1 below
            (including making a pro-rata payment in respect of Services
            performed other than the cGMP batch that produced such Product) or
            requiring LB to repeat the appropriate cGMP batch, for which the
            Customer shall pay LB in accordance with the payment terms set out
            in Schedule 3 applicable to a cGMP batch. In the event Customer
            requires LB to replace such Product, LB shall use all reasonable
            efforts to do so with the minimum delay having regard to its
            commitments to third parties in the timing of such replacement.

            If failure to meet Specification is due to acts or omissions of both
            LB and Customer, then the cost to replace Product shall be
            apportioned to the extent fault lies with each party.

      3.1.3 If for reasons related to the inherent qualities of the Cell Line or
            Product:

            (i)   the Product does not meet the Specification; or

            (ii)  the Product meets the Specification but for other reasons
            cannot be used in a clinical trial;

            then the Customer shall pay to LB the sum of [ * * * ] for the cGMP
            batch that produced such Product.

                                       6

<PAGE>

            If the Services cannot be completed for scientific or technical
            reasons not the fault of either party then the provisions of section
            8.1 (termination) shall apply.

      3.1.4 For the cGMP runs (Stages 8 and 16) Customer shall perform the
            potency testing as set forth in Schedule 1 within thirty (30) days
            of sample receipt from LB. LB shall perform the remaining tests as
            set forth in Schedule 1 within thirty (30) days of completion of the
            run. Each party is entitled to audit the other party's test
            procedures. Prior to the start of the cGMP run the parties shall
            agree on the tests to be run and on the test results necessary for
            the Product to meet Specification. Costs incurred by Customer in
            auditing LB's tests shall be born by Customer. Costs incurred by LB
            in auditing Customer's test shall be born by LB. The Price shall
            include the actual costs incurred by LB in auditing Customer's test.

      3.1.5 LB shall commence the first cGMP batch (Stage 8) within 15 weeks of
            the completion of Stage 6 (bulk fill of 130L pilot batch) but in no
            event later than March 31, 2005. If due to any delays or actions or
            inactions caused solely by LB and not specifically related to
            Customer's Material this first cGMP batch is not commenced by such
            date, then the Customer shall be entitled to terminate this
            Agreement in accordance with Clause 8.1.

      3.1.6 If LB is unable to perform any or all of the Services for a period
            of at least thirty (30) days due to restrictions placed upon LB by
            the FDA or any other regulatory authority, Customer may terminate
            this Agreement in accordance with Clause 8.1 below.

      3.1.7 Prior to the start of the cGMP run each party shall designate in
            writing a Project Manager who shall be the primary contact for each
            party during the provision of the Services. Prior to the start of
            the cGMP Run the parties shall enter into a written Quality
            Agreement which shall be attached as an appendix hereto and
            incorporated by reference as a part of this agreement.

      3.1.8 In accordance with the Quality Agreement, LB shall make available to
            Customer such data and documentation as may be necessary for
            Customer to include in its regulatory filings with the FDA. LB shall
            cooperate as reasonably requested by Customer, at Customer's
            expense, in support of Customer's regulatory filings. Any such
            filings shall be the sole and exclusive property of Customer.

      3.1.9 The parties shall comply with all terms of the Quality Agreement.

3.2   LB shall comply with the International Committee for Harmonisation
      regulatory requirements and all applicable local, state and federal
      regulatory requirements including but not limited to FDA regulations from
      time to time applicable to the Services as set out in Schedule 2.

3.3   LB hereby undertakes not to use the Cell Line, the Customer Materials or
      the Customer Information (or any part thereof) for any purpose except as
      set forth in this Agreement.

3.4   LB shall:

      3.4.1 at all times keep the Cell Line and/or the Customer Materials secure
            and safe from loss and damage in such manner as LB stores its own
            material of similar nature;

      3.4.2 not part with possession of the Cell Line and/or the Customer
            Materials or the Product, save for the purpose of tests at the
            Testing Laboratories; and

                                       7

<PAGE>

      3.4.3 procure that all Testing Laboratories are subject to obligations of
            confidence substantially in the form of those obligations of
            confidence imposed on LB under this Agreement.

3.5   In providing the Services LB shall employ its most current, most efficient
      and best available LB Know How and LB Patent Rights.

4     DELIVERY, TRANSPORTATION OF PRODUCT AND CUSTOMER TESTS

4.1   Product shall be Delivered EXW (ex-works) LB premises (as defined by
      Incoterms 2000) which means (a) when LB places Product at the disposal of
      Customer at LB's premises not cleared for export and not loaded onto any
      collecting vehicle and (b) risk and title to Product pass to Customer upon
      Delivery ("Deliver," "Delivery," or "Delivered," as appropriate). Subject
      to Clause 4.2, unless otherwise instructed by Customer, LB shall not
      Deliver Product to Customer or place Product at the disposal of Customer
      until after Customer has received the Certificate of Analysis and approved
      (in writing) Product for Delivery. Transportation of Product, whether or
      not under any arrangements made by LB on behalf of Customer, shall be made
      at the sole risk and expense of the Customer. Notwithstanding the
      forgoing, Delivery by LB shall not be interpreted as the agreement by
      Customer that the Product meets the Specification.

4.2   At Customer's request, LB will Deliver Product in quarantine prior to
      delivery of the Certificate of Analysis. Such request shall be accompanied
      by Customer's written acknowledgement that the Product has been Delivered
      without the transmittal to Customer of a Certificate of Analysis and, that
      accordingly the Product cannot be administered to humans until transmittal
      of the Certificate of Analysis, and that Customer nevertheless accepts
      full risk of loss, title and ownership of the Product. The Delivery of
      Product in quarantine shall be subject to such testing requirements as LB
      may reasonably require.

4.3   Unless otherwise agreed in writing, LB shall package and label Product for
      Delivery in accordance with its standard operating procedures. It shall be
      the responsibility of the Customer to inform LB in writing in advance of
      any special packaging and labeling requirements for Product. Customer
      shall be responsible for validating any special packaging or vessels
      requested by Customer. All actual additional costs and expenses of
      whatever nature incurred by LB in complying with such special written
      requirements shall be charged to the Customer in addition to the Price.

4.4   If requested in writing by the Customer, LB will (acting as agent for
      Customer) arrange for insurance of Product whilst held by LB after
      Delivery (awaiting transportation) for a maximum of thirty (30) days on
      terms equivalent to those under which LB insures product prior to
      Delivery. All actual additional costs and expenses of whatever nature
      incurred by LB in arranging such insurance shall be charged to the
      Customer in addition to the Price.

4.5   If requested in writing by the Customer, LB will (acting as agent of the
      Customer for such purpose) arrange the transportation of Product from LB's
      premises to the destination indicated by the Customer together with
      insurance cover for Product in transit at its invoiced value. All actual
      additional costs and expenses of whatever nature incurred by LB in
      arranging such transportation and insurance shall be charged to the
      Customer in addition to the Price.

4.6   Where LB has made arrangements for the transportation of Product, the
      Customer shall diligently examine the Product as soon as practicable after
      receipt. Notice of all claims (time being of the essence) arising out of:

      4.6.1 visible damage to or total or partial loss of Product in transit
            shall be given in writing to LB and the carrier within five (5)
            working days of receipt by Customer; or

                                       8

<PAGE>

      4.6.2 non-Delivery shall be given in writing to LB within ten (10) days
            after Customer's receipt of LB's dispatch notice.

4.7   The Customer shall make damaged Product and associated packaging materials
      available for inspection and shall comply with the requirements of any
      insurance policy covering the Product notified by LB to the Customer. LB
      shall offer the Customer all reasonable assistance (at the cost and
      expense of the Customer) in pursuing any claims arising out of the
      transportation of Product.

4.8   If there is any dispute concerning whether Product returned to LB fails to
      meet Specification or whether such failure is due (in whole or in part) to
      acts or omissions of LB, the Customer, or any third party after Delivery,
      or if there is any dispute in relation to clauses 3.1.2 and/or 3.1.3, such
      dispute shall be referred for decision to an independent expert (acting as
      an expert and not as an arbitrator) to be appointed by agreement between
      LB and the Customer or, in the absence of agreement by the President for
      the time being of Biotechnology Industry Organization. The costs of such
      independent expert shall be borne equally between LB and the Customer. The
      decision of such independent expert shall be in writing and, save for
      manifest error on the face of the decision, shall be binding on both LB
      and the Customer.

4.9   The provisions of clauses 3.1.2, 3.1.3 and 4.8 shall be the sole remedy
      available to the Customer in respect of Product that fails to meet
      Specification. This limitation of remedy applies only to Customer's remedy
      with respect to its procurement of such Product and the provisions of
      Article 6 shall nevertheless apply.

5     PRICE AND TERMS OF PAYMENT

5.1   Unless otherwise indicated in writing by LB, all prices and charges are
      exclusive of Value Added Tax or of any other applicable taxes, levies,
      imposts, duties and fees of whatever nature imposed by or under the
      authority of any government or public authority, which shall be paid by
      the Customer (other than taxes on LB's income). All invoices are strictly
      net and payment must be made within thirty (30) days of date of invoice.

      counterclaim of any nature.

            rate in the United States, interest to accrue on a day to day basis
            both before and after judgment; and

      5.2.2 LB shall, at its sole discretion, and without prejudice to any other
            of its accrued rights, be entitled to suspend the provision of the
            Services or to treat this Agreement as repudiated on not less than
            thirty (30) days' prior notice in writing to Customer given at any
            time thereafter.

            Customer Information and Customer Patent Rights) and LB Patent
            Rights and LB Know How for the performance of the Services as

            infringes any intellectual property rights vested in such third
            party.

      against any direct loss, damage, costs and expenses (including court costs
      and legal fees) that Customer may suffer arising directly out of any
      breach of the warranties given by LB in Clause 6.1 or any claims alleging

any liability for death or personal injury resulting directly from negligence by
LB in carrying out the Services or any liability for breach of the implied

7.    CONFIDENTIALITY

7.1   The Customer acknowledges that LB Know-How and LB acknowledges that
      Customer Information with which it is supplied by the other pursuant to
      the Agreement is supplied, subject to Clause 7.5, in circumstances
      imparting an obligation of confidence and each agrees to keep such LB
      Know-How or such Customer Information secret and confidential and to
      respect the other's proprietary rights therein and not at any time for any
      reason whatsoever to disclose or permit such LB Know-How or LB Information
      or such Customer Information to be disclosed to any third party save as
      expressly provided herein.

7.2   The Customer and LB shall each procure that all their respective
      employees, consultants, contractors and persons for whom it is responsible
      having access to confidential LB Know-How or LB Information or
      confidential Customer Information shall be subject to the same obligations
      of confidence as the principals pursuant to Clauses 7.1 and 7.3 and shall
      be bound by secrecy agreements in support of such obligations.

7.3   LB and the Customer each undertake not to disclose or permit to be
      disclosed to any third party (including any contractors or consultants not
      previously approved in writing by LB, such approval not to be unreasonably
      withheld or delayed), or otherwise make use of or permit to be made use of
      (a) any trade secrets or confidential information relating to the
      technology, business affairs or finances of the other, any subsidiary,
      holding company or subsidiary or any such holding company of the other, or
      of any suppliers, agents, distributors, licensees or other customers of
      the other which comes into its possession under this Agreement. or (b) the
      commercial terms of this Agreement except to the extent that the same is
      required to be disclosed pursuant to subpoena, court order, judicial
      process or otherwise by law, provided the Receiving Party provides prompt
      notice to the Disclosing Party of such requirement in order to give the
      Disclosing Party an opportunity to timely seek a protective order or other
      appropriate judicial relief. In the event the Disclosing Party is unable
      to obtain a protective order or other appropriate judicial relief, the
      Receiving Party shall disclose only that portion of the Disclosing Party's
      Confidential Information

                                       11

<PAGE>

      which is legally required to be disclosed, and ensure that all such
      Confidential Information of the Disclosing Party shall be redacted to the
      fullest extent permitted by law prior to such disclosure and that the
      Disclosing Party shall be given an opportunity to review the Confidential
      Information prior to its disclosure.

7.4   The obligations of confidence referred to in this Clause 7 shall not
      extend to any information which:

      7.4.1 is or becomes generally available to the public otherwise than by
            reason of a breach by the Receiving Party of the provisions of this
            Clause 7;

      7.4.2 is known to the Receiving Party and is at its free disposal prior to
            its receipt from the Disclosing Party;

      7.4.3 is subsequently disclosed to the Receiving Party without being made
            subject to an obligation of confidence by a third party;

      7.4.4 LB or the Customer may be required to disclose under any statutory,
            regulatory or similar legislative requirement including but not
            limited to the U.S. Securities and Exchange Commission requirements
            for registrations to sell securities to the public , subject to the
            imposition of obligations of secrecy wherever possible in that
            relation; or

      7.4.5 is developed by any servant or agent of the Receiving Party without
            access to or use or knowledge of the information by the Disclosing
            Party.

7.5   The Customer and LB acknowledge that:

      7.5.1 without prejudice to any other rights and remedies that the parties
            may have, the parties agree that the Confidential Information is
            valuable and that damages may not be an adequate remedy for any
            breach of the provisions of Clauses 7.1, 7.2, 7.3 and 7.4. The
            parties agree that the relevant party will be entitled without proof
            of special damage to the remedies of an injunction and other
            equitable relief for any actual or threatened breach by the other
            party;

      7.5.2 the Customer shall not at any time have any right, title, licence or
            interest in or to LB Know-How, the LB Patent Rights or any other
            intellectual property rights relating to the Process which are
            vested in LB or to which LB is otherwise entitled except as
            otherwise agreed in writing by the parties; and

      7.5.3 LB acknowledges that save as provided herein LB shall not at any
            time have any right, title, licence or interest in or to the
            Customer Information, Customer Patent Rights or any other
            intellectual property rights vested in Customer or to which the
            Customer is entitled.

7.6   Ownership of any technique, process, apparatus, material, product, data,
      formula, software, design, trade secret, Confidential Information,
      improvement, know-how, or invention, whether patentable or not, made in
      performing the services will, save as set out in this section 7.6 follow
      the United States laws of inventorship, and inventors shall be the owners.

7.6.1 In the event that LB develops an invention which relates exclusively to
      the LB Process, Know-how or Patent Rights, and not to Customer Material,
      Information or Patent Rights, LB shall own all right, title and interest
      in and to such invention.

7.6.2 In the event that LB develops an invention which relates exclusively to
      the Customer Material, Information or Patent Rights, and not to the LB
      Process, Know-how or Patent Rights, LB shall promptly provide written
      notice to Customer of such invention and will,

                                       12

<PAGE>

      upon request of Customer, assign such invention to Customer on
      commercially reasonable terms to be negotiated in good faith between the
      parties. For the avoidance of doubt an invention shall not relate
      exclusively to the Customer material if such invention is capable of
      application by LB to materials other than Customer Material.

7.6.3 In the event that LB develops an invention using the Customer Material for
      which no Customer employee is an inventor and which is an invention not
      described in either section 7.6.1 or 7.6.2 above, then LB shall, upon
      request by Customer, grant a nonexclusive license to Customer of such
      invention on commercially reasonable terms to be negotiated in good faith
      by the parties.

7.6.4 In the event that Customer develops an invention relating to the LB
      Process, Know-how or Information during its interaction with LB in the
      performance of the Services, then Customer shall, upon request by LB,
      grant a nonexclusive license to LB of such invention on commercially
      reasonable terms to be negotiated in good faith by the parties.

7.6.5 All notices described in this section 7.6 shall include a detailed
      description of the invention.

7.7   The obligations of LB and the Customer under this Clause 7 shall survive
      the termination for whatever reason of the Agreement.

8.    TERMINATION

8.1   If the parties agree at any stage in the provision of the Services that it
      will not be possible to successfully complete the Services for scientific
      or technical reasons not the fault of either party, a thirty (30) day
      period shall be allowed for good faith discussion and attempts to resolve
      such problems. If such problems are not resolved within such period, or if
      the parties do not agree that scientific or technical reasons prohibit
      successful completion of the Services, LB and the Customer shall each have
      the right to terminate the Agreement forthwith by notice in writing. In
      the event of such termination, the Customer shall pay to LB a termination
      sum calculated by reference to all the Services performed by LB prior to
      such termination including a pro rata proportion of the Price for any
      stage of the Services which is in process at the date of termination
      including the costs of terminating any third party commitments entered
      into pursuant to the Agreement, such sum not to exceed the Price.

8.2   Customer may in its sole discretion terminate the Services at any time for
      any reason by giving not less than (thirty) 30 days' notice in writing to
      LB. In the event of termination pursuant to this Clause 8.2 and subject to
      Clauses 8.3 and 8.4 the Customer shall pay LB a termination sum calculated
      by reference to the Services actually performed by LB prior to termination
      including a pro rata proportion of the Price for any stage of the Services
      which is in process at the date of termination including costs of
      terminating any third party commitments entered into pursuant to this
      Agreement, such sum not to exceed the Price. plus:

      8.2.1 in the event notice to terminate Services pursuant to this Clause
            8.2 is issued to LB six (6) months or less before LB's then
            estimated start date for Stage 8 or Stage 16, or at any time during
            such Stages, Customer shall pay LB a sum equal to the full price of
            that stage or those stages in question, which payment shall fall due
            to LB thirty days from the date of termination of such Services.
            (For the avoidance of doubt, per Schedule 3 the first cGMP run, i.e.
            Stage 8, is already planned to start no later than the end of March
            2005; therefore this clause will require full payment if the first
            cGMP run is cancelled) ; or

      8.2.2 in the event notice to terminate Services pursuant to this Clause
            8.2 is issued to LB more than six (6) months but not more than
            twelve (12) months before LB's then estimated start date for Stage
            8, Customer shall pay LB a sum equal to 85%

                                       13

<PAGE>

            (eighty-five percent) of the full price of Stage 8, which payment
            shall fall due to LB thirty days from the date of termination of
            such Services; or

      8.2.3 in the event notice to terminate Services pursuant to this Clause
            8.2 is issued to LB more than six (6) but not more than nine (9)
            months before LB's then estimated start date for Stage 16, Customer
            shall pay LB a sum equal to twenty five percent (25%) of the full
            price of that stage or those stages in question; which payment shall
            fall due to LB thirty days from the date of termination of such
            Services.

      8.2.4 in the event notice to terminate Services pursuant to this Clause
            8.2 is issued to LB more than nine (9) months before LB's then
            estimated start date for Stage 16 then no payment shall be due to LB
            (For the avoidance of doubt, per Schedule 3, the second cGMP run,
            i.e. Stage 16 is now planned to start by the end of December 2005;
            therefore if Customer cancels this run prior to the end of March
            2005 then no payment shall be owed to LB for the second cGMP run) .

      LB shall use reasonable efforts to mitigate loss and the obligation to
      make payment under Clause 8.1 or clause 8.2 shall be reduced
      (retrospectively, and hence LB shall make an appropriate refund to
      Customer) to the extent that LB mitigates its loss in this regard (and LB
      shall promptly notify the Customer of any such mitigation). This provision
      shall not entitle the Customer to be refunded an amount greater than that
      paid by customer to LB pursuant to this Clause 8.

8.3   For the avoidance of doubt activities relating to the start or
      commencement of a run shall be deemed to commence with the date of removal
      of the vial of cells for the performance of the fermentation from frozen
      storage.

8.4   The parties may each terminate the Agreement forthwith by notice in
      writing to the other party upon the occurrence of any of the following
      events:

      8.4.1 if the other commits a material breach of the Agreement (which shall
            include a breach of the warranties set out in Clauses 2 and 6
            respectively) which in the case of a breach capable of remedy is not
            remedied within thirty (30) days of the receipt by the other of
            written notice identifying the breach and requiring its remedy; or

      8.4.2 if the other ceases for any reason to carry on business or compounds
            with or convenes a meeting of its creditors or has a receiver or
            manager appointed in respect of its assets to which this agreement
            pertains or is the subject of an application for an administration
            order or of any proposal for a voluntary arrangement or enters into
            liquidation (whether compulsorily or voluntarily) or undergoes any
            analogous act or proceedings under foreign law.

8.5   Upon the termination of the Agreement for whatever reason:

      8.5.1 LB shall promptly return to the Customer all Customer Information
            and shall dispose of or return to the Customer the Customer
            Materials (and where supplied by Customer the Cell Line) and any
            materials therefrom, as directed by the Customer;

      8.5.2 the Customer shall promptly return to LB all LB Know-How it has
            received from LB;

      8.5.3 the Customer shall not thereafter use or exploit the LB Patent
            Rights or the LB Know-How in any way whatsoever unless subject to a
            separate written license or agreement;

      8.5.4 LB and the Customer shall do all such acts and things and shall sign
            and execute all such documents as necessary to evidence compliance
            with this Clause 8.5.

                                       14

8.6   Termination of this Agreement for whatever reason shall not affect the
      accrued rights of either LB or the Customer arising under or out of this
      Agreement and all provisions which are expressed to survive the Agreement
      shall remain in full force and effect.

8.6.1 The term of this Agreement shall commence on the date first written above
      and shall expire upon completion of the Services and payment therefor,
      unless earlier terminated as provided herein.

8.7   During the course of this Agreement, and at any time prior to 31st
      December 2007, Customer may request and if requested, LB shall provide to
      Customer a license and technology transfer agreement for relevant
      technical know-how related to the Process, excluding the content of LB's
      proprietary feed additives, to allow Customer or its designee to duplicate
      the Process, under a technology transfer agreement mutually agreed upon,
      subject to commercially reasonable pricing and other terms associated with
      technology transfer. The financial terms for the technology transfer shall
      be negotiated in good faith by the parties, and the total fee for such
      technology transfer will depend on the extent of LB's proprietary know-how
      used in the Process. For the avoidance of doubt, the terms of any such
      technology transfer do not include a licence to LB's proprietary glutamine
      synthetase (GS) gene expression system.

8.8   If prior to 31st December 2006, LB and Customer agree that additional cGMP
      product is to be produced by LB for Customer then the terms for such
      further production at the 2000L scale shall include a price not to exceed
      the Price under this Agreement. All other terms of that agreement will be
      substantially as set forth in this Agreement.

8.9   Should the Customer seek future commercial supply of the Product at 2000L
      or 5000L scale Lonza will enter into good faith negotiations in respect of
      such supply. The price for such supply will be dependent upon selected
      scale, total product requirements and campaign size.

9.    FORCE MAJEURE

9.1   If LB is prevented or delayed in the performance of any of its obligations
      under the Agreement by Force Majeure and shall give written notice thereof
      to the Customer specifying the matters constituting Force Majeure together
      with such evidence as LB reasonably can give and specifying the period for
      which it is estimated that such prevention or delay will continue, LB
      shall be excused from the performance or the punctual performance of such
      obligations as the case may be from the date of such notice for so long as
      such cause of prevention or delay shall continue.

9.2   The expression "Force Majeure" shall be deemed to include any cause
      affecting the performance by LB of the Agreement arising from or
      attributable to acts, events, acts of God, omissions or accidents beyond
      the reasonable control of LB or which LB could not reasonably prevent or
      mitigate; provided, however that unanticipated scientific or technical
      problems shall not constitute Force Majeure. Customer shall have the right
      to terminate this Agreement if a force majeure event continues for a
      period longer than two months.

10.   GOVERNING LAW, JURISDICTION AND ENFORCEABILITY

10.1  The construction, validity and performance of the Agreement shall be
      governed by the laws of the United States and the State of New York, and
      LB and the Customer submit to the non-exclusive jurisdiction of the
      Courts.

10.2  No failure or delay on the part of either LB or the Customer to exercise
      or enforce any rights conferred on it by the Agreement shall be construed
      or operate as a waiver thereof nor shall any single or partial exercise of
      any right, power or privilege or further exercise thereof operate so as to
      bar the exercise or enforcement thereof at any time or times thereafter.

                                       15

<PAGE>

10.3  The illegality or invalidity of any provision (or any part thereof) of the
      Agreement or these Standard Terms shall not affect the legality, validity
      or enforceability of the remainder of its provisions or the other parts of
      such provision as the case may be.
