                 within one hundred and eighty days (180) days of receiving

                 failure within one hundred and twenty (120) days after

                 right to terminate Glycyx's exclusive rights in that country
                 upon written notice to Glycyx;

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

         any adverse condition relating to the safety, quality or efficacy of
         that Product or any other restrictions or delays imposed or caused by
         governmental authorities, or other condition or event beyond Glycyx's
         control that would reasonably justify Glycyx, after consulting with
         Biorex, in exercising prudent and justifiable business judgment, to
         conclude that development or marketing of such Product should be
         delayed, suspended or stopped altogether, and Glycyx's obligation to
         develop or market any such Product shall be delayed or suspended so
         long as any such condition or event exists, but for a maximum of five

         addition, Glycyx shall not be responsible for any delays caused by
         failure of any health regulatory agency to accept data provided by
         Biorex or by inability of Glycyx to obtain, or delays in obtaining,
         sufficient quantities of clinical materials on reasonable terms.

                 or can be used in the Territory without infringing the rights
                 of a Third Party.

7.1      Biorex Fees. Subject to the provisions of Clause 10, Glycyx shall pay
         ------------
         to Biorex [*] percent ([*]%) of all Net Receipts.

7.2      Third Party Royalties. In the event that Glycyx is required to pay to a
         ---------------------
         Third Party any royalties on a Product with respect to technology

8.       REPORTS AND ACCOUNTING

8.1      Reports. After the Commercial Introduction of a Product, Glycyx shall
         -------
         furnish to Biorex on a quarterly basis a written report covering
         Glycyx's fiscal quarters showing, on a country by country basis:

         (i)    Net Receipts for the preceding fiscal quarter;

         (ii)   withholding taxes, if any, required by law to be deducted in
                respect of such amounts; and

         (iii)  the dates of the Commercial Introductions of any Products in any
                country in the Territory during the reporting period.

         Reports shall be due forty-five (45) days following the close of each
         respective quarter. Glycyx shall keep accurate records in sufficient
         detail to enable the Net Receipts to be determined. For the avoidance
         of doubt, Glycyx shall be entitled to enter into Sublicenses in which
         the Sublicensee is required to pay royalties on a semi-annual basis. In
         case no payment is due for any quarter period hereunder, Glycyx shall
         so report.

8.2      Audits
         ------

         8.2.1  Upon the written request of Biorex, at Biorex's expense and not
                more than once each Glycyx fiscal year, Glycyx shall permit or
                procure an independent public accountant selected by Biorex and
                reasonably acceptable to Glycyx to have access during normal
                business hours to such of the records of Glycyx, its
                Sublicensees and Affiliates as may be reasonably necessary to
                verify the accuracy of the Reports made not more than thirty-six
                (36) months prior to the date of such request. Biorex may, at
                its discretion, require Glycyx to arrange such verification of
                Sublicensee reports.

         8.2.2  In the event such accountant concludes that additional amounts
                were owed during such period, the additional amounts shall be
                paid promptly. The fees charged by such accountant shall be paid
                by Biorex unless the audit establishes that the amounts payable
                by Glycyx for the audited period are more than one hundred and
                five percent (105%) of the amounts actually paid for such
                period, in which case Glycyx shall pay the reasonable fees and
                expenses charged by the accountant.

         8.2.3  Upon the expiration of thirty-six (36) months following the date
                of any Report, the calculation of Biorex Fees payable with
                respect to the quarter covered by such Report shall be binding
                and conclusive upon Biorex; and Glycyx shall be released from
                any liability or accountability with respect to Biorex Fees for
                such year.

                                       12


8.3      Confidential Financial Information. Biorex agrees that all information
         ----------------------------------
         subject to review under this Clause 8 is confidential and shall cause
         its accountant to retain all such information in confidence except for
         discussions with Biorex.

9.       PAYMENT TERMS

9.1      Payment of Biorex Fees. Subject to Clause 9.2, amounts shown to have
         ----------------------
         accrued by each Report shall be due and payable on the date such Report
         is due. Glycyx shall use commercially reasonable efforts to ensure
         prompt receipt of Net Receipts.

9.2      Initial License Fees. Glycyx shall forthwith upon receipt of any
         Initial License Fees, pay to Biorex the corresponding Biorex Fee in
         respect of such Initial License Fee by electronic bank transfer into
         the bank account designated by Biorex from time to time for such
         purpose.

9.3      Currency Conversion. All payments to Biorex shall be made in British
         -------------------
         Pounds. Biorex Fees shall be first determined in the currency in which
         such amounts are received by Glycyx and then converted to its
         equivalent in British Pounds. The midpoint between the buying and
         selling rates of exchange for such currency in British Pounds, as
         quoted in The Wall Street Journal (U.S. edition) as of the last
                       -------------------
         business day of the quarter for which the calculation is made, shall be
         used for such conversion, or such other benchmark as may be agreed in
         writing between Biorex and Glycyx from time to time.

9.4      Exchange Control. Notwithstanding Clauses 9.1, 9.2 and 9.3 if at any
         ----------------
         time legal restrictions prevent the prompt remittance of part or all
         payments with respect to any country of the Territory, payment shall be
         made through such lawful means or methods as Biorex may designate.

9.5      Late Payments. Any payments that are not paid on or before the date
         -------------
         such payments are due under this Agreement shall bear interest to the
         extent permitted by applicable law at the time by the base rate laid
         down from time to time by the Bank of England plus one percent,
         calculated on the number of days such payment is delinquent. This
         Clause 9.5 shall in no way limit any other remedy available to either
         party.

10.      INFRINGEMENT

10.1     Infringement Rights. The provisions of this Clause 10 shall govern the
         -------------------
         parties' rights and obligations, as between themselves, with respect to
         actions against and by Third Parties for infringement of patents
         licensed under this Agreement or owned by such Third Parties. In the
         event that either party learns of a significant infringement of the
         Patent Rights within the Territory, it shall promptly notify the other
         party.

                                       13


10.2     Enforcement of Patent Rights.
         ----------------------------

         10.2.1   Glycyx and its Sublicensees shall have the exclusive right to
                  bring, direct and control any action to enforce the Patent
                  Rights against infringers within the Territory.

         10.2.2   Glycyx may deduct from Net Receipts all of its costs and
                  expenses incurred in any quarterly period in enforcing the
                  Patent Rights. Any remaining undeducted costs and expenses may
                  be carried forward and deducted under the same conditions from
                  the Net Receipts in each subsequent quarter.

         10.2.3   After reimbursement to Glycyx for its unreimbursed expenses,
                  all damages and other payments recovered by Glycyx from such
                  infringing parties shall be included in Net Receipts. Biorex
                  shall cooperate with Glycyx, at Glycyx's expense, in
                  connection with any such litigation, including without
                  limitation by joining as a party if necessary or appropriate
                  and executing such documents as Glycyx may reasonably request.

10.3     Third Party Claims. In the event that Glycyx is sued by a Third Party
         ------------------
         alleging that the manufacture, sale or use of a Product in the
         Territory infringes patent rights of such Third Party, then Glycyx may
         withhold up to [*] percent ([*]%) of any Biorex Fees payable in any
         quarter with respect to the region involved in such claim and apply
         such amounts to any damages, costs, liabilities or expenses (including
         the reasonable fees of attorneys and other professionals) incurred as a
         result of such claim up to a maximum of [*] percent ([*]%) of such
         damages, costs, liabilities and expenses. All unreimbursed damages,
         costs liabilities and expenses shall thereafter be deducted in
         calculating the Net Receipts in successive quarters.

11.      CONFIDENTIALITY

11.1     General. Except as expressly otherwise provided in this Agreement, each
         -------
         party shall hold in confidence and not use or disclose to any Third
         Party (other than employees, consultants, advisors, permitted
         Sublicensees and Third Parties with whom such party is considering
         entering into a business relationship who are similarly bound in
         writing) any product, technical, manufacturing, process, marketing,
         financial, business or other information, ideas, or know-how of the
         other party that is identified in writing by the other party as
         confidential ("Proprietary Information") at the time of its disclosure
         or within thirty (30) days thereafter; provided, however, that
         Proprietary Information of a party shall not include:

         11.1.1   Items which at the time of disclosure are published or
                  otherwise generally available to the public;

         11.1.2   Items which, after disclosure to the other party, are
                  published or become generally available to the public through
                  no breach of this Agreement by the other party or the other
                  party's employees or agents; or

[*] CONFIDENTIAL TREATMENT REQUESTED; CERTAIN INFORMATION OMITTED AND FILED
SEPARATELY WITH THE SEC.

                                       14


         11.1.3   Items which the other can document were or are (i) in its
                  possession at the time of disclosure and not acquired directly
                  or indirectly from such party, (ii) independently developed.

11.2     Exceptions.  A party may disclose Proprietary Information of the other:
         ----------

         11.2.1   in connection with the order of a court of law or in
                  compliance with laws or regulations relating to registrations
                  or sale of securities or product approval; or

         11.2.2   if such information is also rightfully acquired from a Third
                  Party who, to the best of such party's knowledge and belief,
                  is entitled to rightfully make such disclosure, but only to
                  the extent such party complies with any restrictions imposed
                  by the Third Party;

         11.2.3   after five (5) years from the date such information is
                  disclosed to it hereunder.

11.3     Licensed Information. Any Proprietary Information of or used by Biorex
         --------------------
         which is or may be subject to an exclusive licence to Glycyx hereunder,
         shall not be disclosed by Biorex to any Third Party for use in the
         Territory except for purposes not inconsistent with such exclusive
         license and only pursuant to confidentiality and non-use restrictions
         at least as restrictive as those provided herein.

11.4     Terms of this Agreement. Glycyx and Biorex agree not to disclose the
         -----------------------
         financial terms or conditions of this Agreement to any Third Party
         without the prior written consent of the other party hereto (which
         consent shall not be unreasonably withheld), except as required by
         applicable law, or to professional advisers, or to persons with whom
         Biorex or Glycyx has entered into or proposes to enter into a business
         relationship for the purposes of raising capital to run their business,
         and then only under conditions of confidence.

12.      PATENT PROSECUTION AND MAINTENANCE

12.1     Control. Glycyx shall have the right to take such actions as are
         -------
         necessary or appropriate, with counsel of its choosing, to effect the
         patent applications within the Patent Rights and to obtain patent
         protection with respect to the subject matter therein in any country
         within the Territory. In the event that Glycyx or a Sublicensee elects
         not to prosecute or maintain a patent application or patent within the
         Patent Rights, Biorex shall have the right to do so at its own expense.

12.2     Expenses. The cost of Glycyx's preparing, filing, prosecuting and
         --------
         maintaining all patent applications and patents contemplated by this
         Agreement shall be borne by Glycyx.

                                       15


12.3     Co-operation. Glycyx shall provide Biorex with copies of all material
         ------------
         documentation after Glycyx's receipt from or prior to submission to any
         governmental agency with jurisdiction to issue such patents, as
         appropriate, so that Biorex may be informed and appraised of the
         continuing prosecution. Glycyx shall consult with Biorex and its
         counsel concerning prosecution of any patent application and adopt
         reasonable suggestions made with respect thereto, and shall use its
         best efforts to amend any patent application to include claims
         reasonably requested by Biorex and required to protect the product
         contemplated to be sold under this Agreement. Biorex shall make
         available to Glycyx or its authorised attorneys, agents or
         representatives, Biorex's employees, agents or consultants necessary or
         appropriate to enable Glycyx to file, prosecute and maintain patent
         applications and resulting patents within the Patent Rights. Biorex
         shall sign or cause to have signed all documents relating to said
         patent applications or patents at no charge to Glycyx.

13.      TERM AND TERMINATION

13.1     Expiration. Unless terminated earlier pursuant to this Clause 13, this
         ----------
         Agreement shall expire fifteen (15) years from the date of Launch. Upon
         expiration of this Agreement, Glycyx shall have an irrevocable,
         non-exclusive, royalty-free licence (with the right to sublicense)
         under the Technical Information and Manufacturing Technology to make,
         have made, use, sell and have sold Products in the Territory.

13.2     Termination for Cause. Either party may terminate this Agreement
         ---------------------
         following the material breach of any material provision of this
         Agreement by the other party if the breaching party has not commenced
         to cure such breach within ninety (90) days after written notice
         thereof by the other party and thereafter proceeded diligently to cure
         such breach within a reasonable time; provided, that in no event shall
         such reasonable time to cure such breach exceed one hundred eighty
         (180) days from the date of such notice. In determining whether there
         has been a material breach of a material provision of this Agreement
         for purposes of this Clause 13.2, all of the circumstances of the
         breach shall be considered, including the breaching party's conduct,
         the hardship of termination, the extent to which the breaching party
         has performed its obligations, the extent to which the non-breaching
         party will obtain the benefits it reasonably anticipated, and similar
         factors.

13.3     Termination by Glycyx. Glycyx shall have the right to terminate this
         ---------------------
         Agreement and the licences granted herein, in whole or as to any
         specified Product or country, at any time, and from time to time, by
         giving notice in writing to Biorex. Such termination shall be effective
         ninety (90) days from the date Biorex receives such notice and all
         Glycyx's rights associated therewith shall cease as of that date;
         provided, however, that if Glycyx revokes in writing its notice of
         termination before the end of such 90 day period, such notice of
         termination shall have no effect and the rights specified in such
         notice of termination shall not terminate.

                                       16


13.4     Termination by Biorex. Without prejudice to any other rights Biorex may
         ---------------------
         have to terminate under this Agreement:

         13.4.1   if Salix or Glycyx ceases business or seeks protection from
                  its creditors pursuant to Chapter 11 of the U.S. Bankruptcy
                  Code or files or has filed against it a voluntary or
                  involuntary bankruptcy procedure that is not dismissed within
                  sixty (60) days or if a receiver or assignee is appointed for
                  the benefit of its creditors or if it takes or suffers any
                  similar action in consequence of debt with respect to all or
                  substantially all of its assets; then Biorex shall have the
                  right to terminate this Agreement forthwith.

         13.4.2   if:

                  (a) a Sublicensee terminates its Sublicense with Glycyx and

                  (b) Biorex and the Sublicensee have either:

                      (i)   prior to the date of the relevant Sublicense
                            agreement; or

                      (ii)  on the same day as the date of the relevant
                            Sublicense agreement; or

                      (iii) after the date of the relevant Sublicense agreement
                            and with the consent of Glycyx, such consent not to
                            be delayed or unreasonably withheld

                      entered into an agreement under which Biorex agrees, in
                      the event of termination of the Sublicense, to grant a
                      licence directly to the Sublicensee;

                  then Glycyx's rights and licenses under this Agreement shall
                  terminate forthwith automatically in respect of the country
                  covered by the relevant Sublicense.

          13.4.3  if:

                  (a) by reason of any act or omission on the part of Glycyx, a
                      Sublicensee is entitled to a royalty-free licence to
                      manufacture Products; and

                  (b) the Sublicensee exercises such right, and such licence
                      continues for more than 180 days

                  then Biorex shall have the right to terminate Glycyx's rights
                  and licenses under this Agreement forthwith in respect of the
                  region covered by the relevant Sublicense.

                                       17


13.5     Effect of Termination.
         ---------------------

         13.5.1   Upon a termination of this Agreement by Glycyx under Clause
                  13.3 above, or by Biorex under Clause 13.4 above, or by reason
                  of a material breach by Glycyx, all licenses granted to Glycyx
                  hereunder (or in the event of a partial termination the
                  licenses to the Products and countries to which such
                  termination pertains) shall terminate. In the event of such a
                  termination, Glycyx shall (to the extent that any applicable
                  Sublicense agreement allows) assign to Biorex filings made in
                  Glycyx's or its Sublicensees name with the health regulatory
                  authorities within the terminated country that pertain to the
                  Products.

         13.5.2   Expiration or termination of this Agreement shall not relieve
                  the parties of any obligation accruing prior to such
                  expiration or termination.

         13.5.3   Upon termination of this Agreement by either party, Glycyx
                  shall provide Biorex with a written inventory of all Products
                  in process of manufacture or in stock, and Glycyx (and its
                  Affiliates and Sublicensees) shall have the privilege of
                  disposing of such Products within a period of one hundred
                  eighty (180) days; provided, however, that Glycyx shall pay
                  Biorex Fees on any sales of such Products at the rate and at
                  the time herein provided and shall render Reports thereon.

         13.5.4   In event of any termination of this Agreement or any licenses
                  granted hereunder, whether in whole or in part, any
                  Sublicense, marketing or other distribution rights granted by
                  Glycyx hereunder shall survive, and the relevant Sublicense
                  and/or distribution agreements, if any, shall be deemed
                  assigned to Biorex, except where Biorex and the relevant
                  Sublicensee enter into an agreement to provide an alternative

14.      INDEMNITY

14.1     Glycyx. Subject to Biorex's compliance with its obligations set forth
         ------
         in Clause 14.3 below, Glycyx agrees to indemnify and hold Biorex, its
         Affiliates and their employees and agents harmless from and against any
         losses, claims, damages, liabilities or actions (including reasonable
         attorneys' fees and court and other expenses of litigation)
         (collectively, the "Liabilities") suffered or incurred in connection
         with Third Party claims for personal injuries or any Product recall to
         the extent caused by:

                                       18


         14.1.1   any failure to test for or provide adequate warnings of
                  adverse side effects to the extent such failure arises out of
                  acts or omissions in connection with the performance of
                  Glycyx's clinical testing obligations hereunder;

         14.1.2   any manufacturing defect in any Product or other material
                  manufactured by Glycyx or its subcontractors; or

         14.1.3   any other act or omission (without regard to culpable conduct)
                  of Glycyx or its subcontractors in connection with the
                  activities contemplated under this Agreement, except to the
                  extent such Liabilities resulted from negligence, recklessness
                  or intentional misconduct of Biorex.

14.2     Biorex. Subject to Glycyx's compliance with its obligations set forth
         ------
         in Clause 14.3, Biorex agrees to indemnify and hold Glycyx, its
         Affiliates, and Sublicensees and their employees and agents harmless
         from and against any Liabilities suffered or incurred in connection
         with third party claims for personal injuries or any Product recall to
         the extent caused by:

         14.2.1   any failure to test for or provide adequate warnings of
                  adverse side effects to the extent such failure arises out of
                  acts or omissions in connection with Biorex's clinical testing
                  obligations hereunder;

         14.2.2   any manufacturing defect in any Product or other material
                  manufactured by Biorex or its subcontractors; or

         14.2.3   any other act or omission (without regard to culpable conduct)
                  of Biorex or its subcontractors in connection with the
                  activities contemplated under this Agreement, except to the
                  extent such Liabilities resulted from negligence, recklessness
                  or intentional misconduct of Glycyx or its Affiliates,
                  sublicensees or subcontractors.

         Notwithstanding the foregoing, Biorex shall not be obligated to
         indemnify Glycyx or its Affiliates, Sublicensees or subcontractors with
         respect to Liabilities incurred in the course of human clinical trials
         conducted by Glycyx (itself or through subcontractors), or with respect
         to Liabilities resulting from the use of Products supplied by Biorex as
         clinical trials materials for use in such clinical trials.

14.3     Procedure. A party (the "Indemnitee") that intends to claim
         ---------
         indemnification under this Clause 14 shall promptly notify the other
         party (the "Indemnitor") in writing of any loss, claim, damage,
         liability or action in respect of which the Indemnitee or any of its
         Affiliates, employees or agents intend to claim such indemnification,
         and the Indemnitor shall have the right to participate in, and, to the
         extent the Indemnitor so desires, jointly with any other Indemnitor
         similarly noticed, to assume the defence thereof with counsel mutually
         satisfactory to the parties; provided, however, that an Indemnitee
         shall have the right to retain its own counsel, with the fees and
         expenses to be paid by the Indemnitee, if representation of such
         Indemnitee by the counsel retained by the

                                       19


         Indemnitor would be inappropriate due to actual or potential differing
         interests between such Indemnitee and any other party represented by
         such counsel in such proceeding. The indemnity agreement in this Clause
         14 shall not apply to amounts paid in settlement of any loss, claim,
         damage, liability or action if such settlement is effected without the
         consent of the Indemnitor, which consent shall not be withheld
         unreasonably. The failure to deliver written notice to the Indemnitor
         within a reasonable time after the commencement of any such action, if
         prejudicial to its ability to defend such action, shall relieve such
         Indemnitor of any liability to the Indemnitee under this Clause 14, but
         the omission so to deliver written notice to the Indemnitor shall not
         relieve it of any liability that it may have to any Indemnitee
         otherwise than under this Clause 14. The Indemnitee under this Clause
         14, its employees and agents, shall cooperate fully with the Indemnitor
         and its legal representatives in the investigation of any action, claim
         or liability covered by this indemnification.

15.      FORCE MAJEURE

         Neither party shall be held liable or responsible to the other party
         nor be deemed to have defaulted under or breached this Agreement for
         failure or delay in fulfilling or performing any term of this Agreement
         when such failure or delay is caused by or results from causes beyond
         the reasonable control of the affected party or from fire, floods,
         embargoes, war, acts of war (whether war be declared or not),
         insurrections, riots, civil commotions, strikes, lockouts or other
         labour disturbances, acts of God or acts, omissions or delays in acting
         by any governmental authority or the other party.

16.      ASSIGNMENT

         This Agreement may not be assigned or otherwise transferred, nor,
         except as expressly provided hereunder, may any right or obligations
         hereunder be assigned or transferred, by either party without the
         written consent of the other party; provided, however that either
         Biorex or Glycyx may, without such consent, assign this Agreement and
         its rights and obligations hereunder in connection with the transfer or
         sale of all or substantially all of its business, if such assets
         include substantially all of the assets relating to its performance of
         its respective obligations hereunder, or in the event of its merger or
         consolidation with another company at any time during the term of this
         Agreement. Any purported assignment in violation of the preceding
         sentence shall be void. Any permitted assignee shall assume all
         obligations of its assignor under this Agreement. No assignment shall
         relieve either party of responsibility for the performance of any
         accrued obligation which such party then has hereunder.
