2.        DEVELOPMENT COMMITTEE

2.1       With effect from the Commencement Date the Parties shall establish and

          2.1.1     the DC shall comprise two (2) persons as voting members
                    ("Members") and Ardana and Columbia respectively shall be
                    entitled to appoint one (1) Member and to replace the Member
                    appointed by it. The initial Members shall be appointed by
                    each Party prior to the first DC meeting. Ardana and
                    Columbia respectively shall each notify the other of any
                    change in the identities of their Member from time to time.
                    Both sides shall use reasonable endeavours to keep an
                    appropriate level of continuity in representation. Members
                    may be represented at any meeting by another person
                    designated

                                       22

             SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION.



                    by the absent Member. Meetings of the DC shall be co-chaired
                    by the two Members and such co-chairpersons shall only be
                    entitled to exercise one (1) vote each as Members at the DC
                    and shall not have any right to a veto or casting vote;

          2.1.2     the quorum for meetings of the DC shall be the two (2)
                    Members. Conclusions and decisions of the DC shall be made
                    by unanimous agreement of the Members present wherever
                    possible and shall be minuted by or upon behalf of the
                    Chairpersons. Both Parties will use their reasonable efforts
                    to build consensus. If the DC does not reach unanimous
                    agreement regarding any matter such matter shall be referred
                    for resolution to the Chief Executive Officer of each Party;

          2.1.3     the venue for meetings not held by teleconference shall
                    alternate between the offices of Ardana in Edinburgh,
                    Scotland and the offices of COB in Livingston, New Jersey or
                    such other venue as may be agreed. Each Party shall be
                    responsible for its own expenses including travel and
                    accommodation costs incurred in connection with DC meetings;

          2.1.4     notwithstanding that each Party shall have only one Member
                    of the DC the Parties acknowledge that other individuals may
                    attend from either Party which additional attendees may
                    change according to the subject matter of DC meeting. Each
                    Party shall give the other reasonable advance notice of the
                    identity of any such additional attendees which it intends
                    to participate in the DC meeting in question. For the
                    avoidance of doubt it is agreed that such persons shall not
                    be Members and shall not have a right to vote or participate
                    in the decision making process of the DC; and

          2.1.5     the DC Members shall take alternate responsibility for
                    promptly preparing the minutes of any DC meeting, receiving
                    approval of those minutes from the other DC Member who
                    participated in the meeting, signing and dating the approved
                    minutes and promptly distributing a copy of the signed
                    minutes to each Party. It is only such signed and dated
                    minutes which shall constitute a decision of the DC.

                    co-development and Commercialisation of Candidate Product
                    and resultant Product this shall be an Ardana Positive
                    Election or a Columbia Positive Election, respectively.

          4.1.2     If Ardana or Columbia elects not to continue with the
                    co-development and Commercialisation of Candidate Product
                    and resultant Product this shall be an Ardana Negative
                    Election or a Columbia Negative Election, respectively.

4.2       In the event of an Ardana Positive Election and a Columbia Positive
          Election the Parties shall proceed with the co-development and
          Commercialisation of the Candidate Product and the resultant Product

                    terms of this Agreement have the exclusive right to

                    for their respective tasks under the Second Development

          4.2.4     the Parties shall agree the approach to be taken for the

          Election, Columbia shall have [***] to elect to change its position to

          and the Commercialisation Committee shall not be formed, Ardana shall
          on the terms of Clause 13.6 have the exclusive fully paid up royalty
          free right to continue with the worldwide development and
          commercialisation of Candidate Product and resultant Product either

          14.3, 14.4, 14.6, and 14.7 shall continue to apply and shall be deemed

          Ardana's sole reasonable expense: (1) for any additional filings
          requested by Ardana with regard to any Columbia IP over and above
          those filings which exist as of the Commencement Date, and (2) for any
          filings of Columbia IP regarding Columbia Technology developed after
          the Commencement Date requested by Ardana in countries other than
          those listed in Exhibit E. So long as Columbia's election remains a
          Negative Election, Ardana shall assume sole responsibility for the
          prosecution, maintenance, defence and enforcement of Joint Program IP
          at its own cost and expense, providing Columbia with at least 60 days
          advance notice, with copies, of all proposed filings and proposed
          correspondence, and prompt copies of all actual filings and
          correspondence. Columbia shall retain joint ownership in the Joint
          Program IP with rights to use or exploit the Joint Program IP other
          than with regard to the Candidate Product and resultant Product (in
          either case with any indication). If Ardana does not significantly
          continue and forward the development and commercialization of the
          Candidate Product and resulting Product consistent with Good Industry
          Practice in [***], all of Ardana's exclusive rights to the Joint
          Program IP regarding the Candidate Product and resultant Product shall
          become non-exclusive as to Columbia.

4.4       In the event of a Columbia Positive Election and an Ardana Negative
          Election, Ardana shall have [***] to elect to change its position to a
          Positive Election, in which

          case Clause 4.2 shall apply. However, if Ardana maintains its Negative
          Election, the DC shall be disbanded and the Commercialisation
          Committee shall not be formed, Ardana shall lose all rights under, and
          shall not use or exploit in any way the Columbia IP, and Columbia
          shall on the terms of Clause 13.7 have the exclusive fully paid up
          royalty free right to continue with the worldwide development and
          commercialisation of Candidate Product and resultant Product either
          alone or in conjunction with a Third Party without further obligation
          to Ardana. In such circumstances the provisions of Clauses 14.3, 14.6
          and 14.7 shall continue to apply. So long as Ardana's election remains
          a Negative Election, Columbia shall assume sole responsibility for the
          prosecution, maintenance, defence and enforcement of Joint Program IP
          at its own cost and expense, providing Ardana with at least 60 days
          advance notice, with copies, of all proposed filings and proposed
          correspondence, and prompt copies of all actual filings and
          correspondence. Ardana shall retain joint ownership in the Joint
          Program IP with rights to use or exploit the Joint Program IP other
          than with regard to the Candidate Product and resultant Product (in
          either case with any indication). If Columbia does not significantly
          continue and forward the worldwide development and commercialization
          of the Candidate Product and resulting Product consistent with Good
          Industry Practice in [***], all of Columbia's exclusive rights to the
          Joint Program IP regarding the Candidate Product and resultant Product
          shall become non-exclusive as to Ardana.

4.5       In the event of an Ardana Negative Election and a Columbia Negative
          Election, the DC shall be disbanded and the Commercialisation
          Committee shall not be formed. Ardana shall not use or exploit in any
          way whatsoever the Columbia IP, and neither Party shall use or exploit
          in any way whatsoever the Joint Program IP in relation to the
          Candidate Product or resultant Product for any indication, without the
          other Party's prior written consent. Each of the Parties shall use
          their reasonable efforts to find and appoint a Third Party to continue
          the worldwide development and commercialisation of the Candidate
          Product and resultant Product. The Parties shall agree upon a
          co-ordinated approach to this if this eventuality arises. The
          appointment of such Third Party shall be on the basis that such Third
          Party shall be granted an exclusive worldwide licence under the
          Columbia IP and each Party's interest in the Joint Program IP to
          develop, use, import, have imported, market, distribute and sell or
          have marketed, distributed and sold Candidate Product and resultant
          Product for all

          indications. The Net Revenues from any such Third Party appointment
          shall be shared equally between the Parties on the terms of Clause 8.
          Columbia agrees that it shall either manufacture and supply to such
          Third Party its requirements of CTM and Finished Product for [***]
          (which shall be paid separately to Columbia by such Third Party as a
          term of the licensing agreement with such third party) or shall grant
          such Third Party appropriate royalty-bearing licences under the
          Columbia IP to permit such Third Party to manufacture or have
          manufactured such CTM and Finished Product. The Net Revenues from any
          such royalty-bearing licences shall be shared equally between the
          Parties on the terms of Clause 8.

5.        SECOND DEVELOPMENT PROGRAM

5.1       As soon as practicable following an Ardana Positive Election and a
          Columbia Positive Election the Parties shall cause the DC to meet to
          agree the detailed work program for the Second Development Program and
          the Development Budget for the first Year of the Second Development
          Program. The Parties agree that in relation to any Clinical Trials to
          be carried out as part of the Second Development Program:

          5.1.1     Ardana shall be the sole sponsor of and for organising any
                    such Clinical Trials to be carried out in the Ardana
                    Territory and for the Development Costs to be paid in
                    respect thereof (recouping the appropriate share of such
                    Development Costs under the provisions of Clause 5.3) and
                    Ardana shall make all Regulatory Applications in respect of
                    such Clinical Trials or in respect of any subsequent
                    Marketing Authorisation in the Ardana Territory in its own
                    name;

          5.1.2     Columbia shall be the sole sponsor of and for organising any
                    such Clinical Trials to be carried out in the Columbia
                    Territory and for the Development Costs to be paid in
                    respect thereof (recouping the appropriate share of such
                    Development Costs under the provisions of Clause 5.3) and
                    Columbia shall make all Regulatory Applications in respect
                    of such Clinical Trials or in respect of any subsequent
                    Regulatory Approval in the Columbia Territory in its own
                    name.

5.2       Subject to the provisions of Clause 5.1 each Party shall carry out
          those tasks and parts of the work program for the Second Development
          Program allocated to it by the DC provided always that neither Party
          shall be obliged to commit more FTE to the Second Development Program
          in any Year than determined under Clause 2.2.4.

5.3       The Parties shall be jointly responsible on a 50:50 basis for all
          Development Costs incurred by them in carrying out the Second
          Development Program. Within thirty (30) days of the end of each
          Quarter each party shall supply the other with a report of the
          Development Costs paid by it during that Quarter which report shall
          set out the tasks undertaken (which tasks shall be cross-referenced to
          the Second Development Program) and the Development Costs paid in
          relation to such task. Within forty-five (45) days of the end of each
          Quarter there shall be a reconciliation prepared of the Development
          Costs incurred during such Quarter by the Parties which reconciliation
          shall be in the form of an invoice from one Party to the other Party
          and a balancing payment as necessary by such Party to the other shall
          be made so that each Party has borne 50% of the Development Cost for
          that Quarter. For the avoidance of doubt it is declared and agreed
          that the sharing of Development Costs shall commence from the point
          that each Party makes a positive election pursuant to Clause 4 and the
          Parties acknowledge and agree that subject to the provisions of Clause
          3.3 any costs and expenses incurred prior to that date are not
          chargeable to Development Costs.

5.4       If at the time that the DC seeks ratification of the Development
          Budget for any Year during the Second Development Program or the FTE
          commitment for any Year it is not so ratified by either Party's Chief
          Executive Officer in writing within 3 months of the commencement of
          the Year to which it relates (such Party's reasonable request for
          changes to the Second Development Program and consequential changes to
          the Development Budget or FTE commitment having been acceded to by the
          other Party) this shall be deemed notice of withdrawal from the Second
          Development Program by the Party refusing to ratify. Upon any such
          notice of withdrawal:

          5.4.1     the provisions of Clauses 4.3 and 4.4 shall be deemed to
                    apply such that the continuing Party shall have the fully
                    paid up royalty free worldwide right to continue alone with
                    development, commercialization, marketing, and sale of
                    Candidate Product and any resulting Product;

             SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION.



          5.4.2     the withdrawing Party shall upon the continuing Party's
                    written request deliver up to the continuing Party all
                    Documents containing any Know How (save for a single copy to
                    be retained for evidential purposes by the withdrawing
                    Party's lawyers), and any other Know How, held by the
                    withdrawing Party relating to the Candidate Product and/or
                    the resultant Product;

          5.4.3     the withdrawing Party shall not use or otherwise exploit in
                    any way, either directly or indirectly the Joint Program IP
                    as it relates to the Candidate Product or any resulting
                    Product in either case for all indications;

          5.4.4     only the continuing Party shall be free to use and exploit
                    all Joint Program IP as it relates to the Candidate Product
                    or any resulting Product in either case for all indications
                    as it sees fit with no obligation to the withdrawing Party
                    in respect thereof provided however that both Parties shall
                    be free to use and exploit all Joint Program IP, except as
                    it relates to the Candidate Product or any resulting Product
                    in either case for all indications, as each sees fit with no
                    obligation to the withdrawing Party in respect thereof;

          5.4.5     if the withdrawing Party is Columbia the licences granted by
                    Columbia to Ardana pursuant to Clause 13.6 shall continue in
                    full force and effect and shall be extended to the Columbia
                    Territory and ROW and Columbia shall do all such acts and
                    things as may be necessary to perfect this obligation and
                    the provisions of Clauses 14.1, 14.3, 14.4, 14.6, and 14.7
                    shall continue to apply and shall be deemed expanded in
                    scope to place similar obligations on Columbia in relation
                    to non-European Columbia IP owned by Columbia at Ardana's
                    request and sole reasonable expense. In such circumstances
                    Ardana shall assume sole responsibility for the prosecution,
                    maintenance, defence and enforcement of Joint Program IP at
                    its own cost and expense, under the same terms, obligations,
                    and consequences, and the same standards for maintaining
                    exclusive rights, as set forth in Clause 4.3;

          5.4.6     if the withdrawing Party is Ardana the licence granted by
                    Ardana to Columbia pursuant to Clause 13.7 shall continue in
                    full force and effect and shall be extended to the Ardana
                    Territory and ROW and Ardana shall do all

                    such acts and things as may be necessary to perfect this
                    obligation and the provisions of Clauses 14.3, 14.6, and
                    14.7 shall continue to apply. In such circumstances Columbia
                    shall assume sole responsibility for the prosecution,
                    maintenance, defence and enforcement of Joint Program IP at
                    its own cost and expense, under the same terms, obligations,
                    and consequences, and the same standards for maintaining
                    exclusive rights, as set forth in Clause 4.4;

          5.4.7     if the withdrawing Party is Columbia and it has obligations
                    to manufacture and supply CTM and Finished Product under the
                    terms of a Manufacturing and Supply Agreement entered into
                    pursuant to Clause 9 these shall continue;

          5.4.8     the withdrawing Party shall commensurate with legislative
                    and regulatory requirements, transfer to the continuing
                    Party or its nominee all Regulatory Approvals, Marketing
                    Authorisations, Regulatory Applications and other regulatory
                    filings and approvals for Candidate Product or resultant
                    Product in all countries of the territory of the withdrawing
                    Party and any country in the ROW Territory in relation to
                    which the withdrawing Party has been appointed the
                    Responsible Party pursuant to Clause 8. In the event that in
                    any country such a transfer is not possible, the withdrawing
                    Party shall use reasonable endeavours to ensure that the
                    continuing Party has the benefit of the relevant Regulatory
                    Approvals, Marketing Authorisations, Regulatory applications
                    and other regulatory filings and approvals and, to this end,
                    consents to any Governmental Authority cross-referencing to
                    the data and information on file with any Governmental
                    Authority as may be necessary to facilitate the granting of
                    second Marketing Authorisations, applications, regulatory
                    filings and approvals to the continuing Party, and the
                    withdrawing Party agrees to complete whatever other
                    procedures are reasonably necessary in relation to the same
                    to enable the continuing Party (either itself or in
                    conjunction with a third party) freely to develop and sell
                    the Product in substitution for the withdrawing Party; and

          5.4.9     the withdrawing Party shall use its reasonable endeavours to
                    assign to the continuing Party the benefit of any agreement
                    made between the

                    Product in ROW or any agreement between the withdrawing
                    Party and an agent or distributor in any country to which
                    Clause 8.1 relates.

5.5       In the event that during the course of the Development Program the DC
          identifies a strategic, legal, commercial, safety, efficacy,
          formulation, scientific or technical reason which means that both
          Parties wish to abandon the development of the Candidate Product, then
          this Agreement shall terminate by their mutual agreement to do so
          (such mutual agreement being said decision of the DC ratified by both
          the CEO of Ardana and the CEO of Columbia). Following any such
          termination Ardana shall not use or exploit in any way whatsoever the
          Columbia IP, and both Parties shall not use or exploit the Joint
          Program IP in relation to the Candidate Product or resultant Product
          in either case for any indication without the other Party's prior
          written consent.

5.6       In the event that the Second Development Program continues to its
          satisfactory conclusion and filings for Regulatory Approval are made
          in the Columbia Territory and filings for Marketing Authorisation are
          made in the Ardana Territory as specified in Clause 5.1 and
          subsequently such Regulatory Approvals and/or Marketing Authorisations
          are granted:

          5.6.1     Columbia shall own and hold the Regulatory Approvals for the
                    Columbia Territory and thereafter shall be solely
                    responsible for ensuring that all Applicable Laws and other
                    regulatory or other obligations arising as a result thereof
                    or in relation thereto are met.

          5.6.2     Ardana shall own and hold the Marketing Authorisations for
                    the Ardana Territory and thereafter shall be solely
                    responsible for ensuring that all Applicable Laws and other
                    regulatory or other obligations arising as a result thereof
                    or in relation thereto are met.

          5.6.3     Columbia shall be solely responsible (as between Columbia
                    and Ardana) at its own cost and expense for the
                    Commercialisation of the Product in the Columbia Territory
                    and shall have the exclusive benefit of all revenues
                    generated in relation thereto. It is agreed that whilst the
                    final decision on

                    Packaging and Labelling shall be Columbia's, the Packaging
                    and Labeling will be marked with all relevant patent numbers
                    in each country of the Territory, as may be required by
                    local patent law or practice or otherwise permitted under
                    Applicable Law and the MAs.

          5.6.4     Ardana shall be solely responsible (as between Ardana and
                    Columbia) at its own cost and expense for the
                    Commercialisation of the Product in the Ardana Territory and
                    shall have the exclusive benefit of all revenues generated
                    in relation thereto. It is agreed that whilst the final
                    decision on Packaging and Labelling shall be Ardana's, the
                    Packaging and Labeling will be marked with all relevant
                    patent numbers in each country of the Territory, as may be
                    required by local patent law or practice or otherwise
                    permitted under Applicable Law and the MAs.

          5.6.5     As and when any variation to any Regulatory Approval or
                    Marketing Authorisation is made each Party shall supply a
                    copy thereof to the other Party.

          5.6.6     The Parties shall co-ordinate and liaise with each other in
                    connection with Commercialisation of the Product in the
                    Ardana Territory and Columbia Territory respectively and
                    shall establish a separate committee for this purpose. In
                    particular but not limiting the foregoing each party shall
                    supply details of its Commercialisation Know How to the
                    other. The Commercialisation Committee:

                    (a)  shall be constituted as specified in Clause 2.1.1;

                    (b)  shall be purely a co-ordination, liaison and
                         communication forum and shall not be a decision making
                         body (all decisions about Commercialisation being
                         reserved exclusively to Ardana in respect of the Ardana
                         Territory and Columbia in respect of the Columbia
                         Territory);

          day period the withdrawing party shall be free to solicit interest
          from other Third Party licensees in respect of such territory and if

          10.1.1    each Party agrees to keep the other Party informed,
                    commencing within two (2) working days of notification of
                    any action by, or notification or other information which it
                    receives (directly or indirectly) from any Governmental
                    Authority, which (a) raises any material concerns regarding
                    the safety or efficacy of any Product, or (b) which
                    indicates or suggests a potential material liability for
                    either Party to third parties arising in connection with any
                    Product.

          10.1.2    each Party agrees to keep the other Party regularly informed
                    of all material correspondence and communications with any
                    Governmental Authority in its Territory concerning the
                    manufacture, Specification, quality, Packaging or labeling
                    of the Finished Product.

          reasonable directions of the other Party concerning any meeting or

                    the First Development Program.

11.2      Each Party shall keep and shall procure that its Affiliates, agents,
          distributors and sublicensees keep true and accurate records and books
          of account containing all data necessary for the calculation of the
          amounts payable by it to the other Party pursuant to this Agreement,
          and in particular but without limitation data relating to the
          calculation of Net Revenues and Development Costs. Those records and
          books of account shall be kept for seven (7) years following the end
          of the Year to which they relate. Upon a Party's (the "Assessing
          Party") written request a firm of independent accountants appointed by
          approval of the Parties which approval shall not be unreasonably
          delayed or withheld, shall carry out an audit procedure in relation to
          the other party (the "Assessed Party") and:

          11.2.1    such firm of accountants shall be given access to and shall
                    be permitted to examine and copy such books and records upon

                    Assessing Party and at all reasonable times on Business Days
                    for the purpose of certifying to the Assessing Party that
                    the Net Revenues and Development Costs calculated by the
                    Assessed Party its Affiliates and/or agents, distributors or
                    licensees during any Year was calculated currently in
                    accordance with this Agreement and if such certification
                    cannot be given specifying the reasons why which will enable
                    the Parties to recalculate the relevant sums;

             SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION.



          11.2.2    prior to any such examination taking place, such firm of
                    accountants shall undertake to the Assessed Party in a deed
                    that they shall keep all information and data contained in
                    such books and records, strictly confidential and shall not
                    disclose such information or copies of such books and
                    records to any third person including the Assessing Party,
                    but shall only use the same for the purpose of the
                    calculations which they need to perform in order to issue
                    the certificate to the Assessing Party which this Clause
                    11.2 envisages;

          11.2.3    any such access examination and certification shall occur no
                    more frequently than once per year and will not go back over
                    records more than two (2) years old unless a discrepancy is
                    found;

          11.2.4    the Assessed Party shall make available personnel to answer
                    queries on all books and records required for the purpose of
                    that certification; and

          11.2.5    if the certification shows that the Assessed Party has not
                    calculated the Net Revenues and Development Costs correctly
                    the Parties shall forthwith recalculate these sums and any
                    monies which such recalculation shows as being due and owing
                    by one Party to the other shall be paid by that Party. The
                    cost of the accountant shall be the responsibility of the
                    Assessed Party if the recalculation shows the Assessed
                    Party's previous figures supplied to the Assessing Party to
                    be inaccurate by more than five per cent (5%) and the
                    responsibility of the Assessing Party otherwise.

11.3      All payments under the terms of the Agreement are expressed to be
          exclusive of value added tax howsoever arising.

11.4      Unless otherwise approved or reasonably directed in writing by the
          Parties, all payments made by the Parties shall be made in United
          States dollars. All cost of foreign currency conversion to United
          States dollars shall be paid by the party making the payment without
          deductions for taxes, assessments, fees or charges of any kind. All
          payment amounts shall be converted to United States dollars on the
          last business day of each calendar month. Any necessary currency
          conversions shall be made using the United States dollar buying price
          quoted for such conversion into United States

             SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION.



13.1      Columbia hereby grants to Ardana a sole worldwide sub-licensable
          licence under the Columbia IP only for the purposes of carrying out
          the First Development Program. Columbia and Ardana hereby grant to
          each other the sub-licensable right for each other and their
          Affiliates to use the Joint Program IP for the purposes of carrying
          out the First Development Program.

13.2      If Ardana makes an Ardana Positive Election and Columbia makes a
          Columbia Positive Election pursuant to Clause 4 Ardana hereby grants
          to Columbia an exclusive fully paid up royalty free licence with the
          right to sub-license in accordance with Clause 13.3 in the Columbia
          Territory under Ardana's interest in the Joint Program IP to use the
          same as may be necessary in connection with the Second Development
          Program and to develop, have developed, make, have made, anywhere in
          the world, and to import, have imported, market, distribute and sell
          and have marketed, distributed and sold the Product only in the
          Columbia Territory.

13.3      Columbia shall be entitled to sublicense the rights granted to it
          under Clause 13.2 to any Affiliate and to Third Parties provided that
          Columbia has notified Ardana of the identity of any intended
          sublicensee (including in circumstances where the sublicensee is an
          Affiliate of Columbia, other than COB) and provides Ardana with a copy
          of any such sublicence at the same time as it is made. Columbia shall
          only have the right to sub-license any such rights on the basis that
          Columbia shall notify Ardana of the identity of any proposed third
          party licensee and Ardana shall have thirty (30) days to approve such
          licensee (which approval shall not be unreasonably withheld) and
          provided that the terms of appointment of such licensee shall prevent
          the further appointment of sub-licensees without first obtaining
          Ardana's prior written approval (which approval may be withheld by
          Ardana in its sole discretion). Notwithstanding this permission to
          sub-license Columbia shall remain responsible for all of its
          obligations hereunder and if the acts or omissions of any such
          sublicensee cause Columbia to be in breach of this Agreement Columbia

          provided for under this Agreement and any implied consequences)
          regardless of any remedy which Columbia may have against the
          sublicensee for breach of the sublicence. In particular but without
          limitation, Columbia shall ensure that any sublicensee performs its
          financial obligations under that sublicence and Columbia indemnifies
          Ardana against any and all loss, damage,

          cost or expense which Ardana may incur as a result of failure by a
          sublicensee of Columbia to perform such obligations.

13.4      If Ardana makes an Ardana Positive Election and Columbia makes a
          Columbia Positive Election pursuant to Clause 4 Columbia hereby grants
          to Ardana an exclusive fully paid-up, royalty-free licence with the
          right to sublicence in accordance with Clause 13.5 in the Ardana
          Territory under the Columbia IP and under Columbia's interest in the
          Joint Program IP in both cases such licence being to use the same as
          may be necessary in connection with the Second Development Program and
          to develop, have developed, make, have made, anywhere in the world,
          and to import, have imported, market, distribute, sell and have
          marketed, distributed and sold the Product only in the Ardana
          Territory. Ardana undertakes and agrees that unless and until it
          exercises its right to manufacture or have manufactured Product and/or
          Finished Product under the provisions of or following the consequences
          of Clauses 18.5.6 and 18.6 of this Agreement it shall not utilise the
          license granted to it under this Clause 13.4 to manufacture or have
          manufactured Product and/or Finished Product but instead shall obtain
          all of its requirements for the same from Columbia on the terms of
          Clause 9 of this Agreement.

13.5      Ardana shall be entitled to sublicense the rights granted to it under
          Clause 13.4 to any Affiliate and to Third Parties provided that Ardana
          has notified Columbia of the identity of any intended sublicensee
          (including in circumstances where the sublicensee is an Affiliate of
          Ardana) and provides Columbia with a copy of any such sublicence at
          the same time as it is made. Ardana shall only have the right to
          sub-license any such rights on the basis that Ardana shall notify
          Columbia of the identity of any proposed third party licensee and
          Columbia shall have thirty (30) days to approve such licensee (which
          approval shall not be unreasonably withheld) and provided that the
          terms of appointment of such licensee shall prevent the further
          appointment of sub-licensees without first obtaining Columbia's prior
          written approval (which approval may be withheld by Columbia in its
          sole discretion). Notwithstanding this permission to sub-license
          Ardana shall remain responsible for all of its obligations hereunder
          and if the acts or omissions of any such sublicensee cause Ardana to
          be in breach of this Agreement Ardana shall be responsible therefor
          (with all the express consequences provided for under this Agreement
          and any implied

                                       51

          consequences) regardless of any remedy which Ardana may have against
          the sublicensee for breach of the sublicence. In particular but
          without limitation, Ardana shall ensure that any sublicensee performs
          its financial obligations under that sublicence and Ardana indemnifies
          Columbia against any and all loss, damage, cost or expense which
          Columbia may incur as a result of failure by a sublicensee of Ardana
          to perform such obligations.

13.6      If Ardana makes an Ardana Positive Election pursuant to Clause 4 but
          Columbia makes and does not reverse a Columbia Negative Election
          pursuant to Clause 4 Columbia hereby grants to Ardana a worldwide
          exclusive fully paid-up, royalty-free, sub-licensable licence under
          the Columbia IP and under Columbia's interest in the Joint Program IP
          only to develop or have developed Candidate Product for all
          indications and to make, have made, use, import, have imported,
          market, distribute, sell and have marketed, distributed and sold the
          Product for all indications. Ardana undertakes and agrees that unless
          and until it exercises its right to manufacture or have manufactured
          Product and/or Finished Product under the provisions of or following
          the consequences of Clauses 18.5.6 and 18.6 of this Agreement it shall
          not utilise the license granted to it under this Clause 13.6 to
          manufacture or have manufactured Product and/or Finished Product but
          instead shall obtain all of its requirements for the same from
          Columbia on the terms of Clause 9 of this Agreement.

13.7      If Columbia makes a Columbia Positive Election pursuant to Clause 4
          but Ardana makes and does not reverse an Ardana Negative Election
          pursuant to Clause 4, Ardana hereby grants to Columbia a worldwide
          exclusive, fully paid-up, royalty-free worldwide, sub-licensable
          licence under Ardana's interest in the Joint Program IP only to
          develop or have developed Candidate Product for all indications and to
          make, have made, use, import, have imported, market, distribute and
          sell and have marketed, distributed and sold Product for all
          indications.

13.8      The Parties shall do all such acts and things and shall execute all
          such deeds and documents as may be necessary or desirable to register
          any of the foregoing licences at local patent offices.

13.9      Each Party shall, and shall procure that its Affiliates shall, during
          the Term promptly refer to the other Party (or as the other Party
          shall direct) all enquiries they receive for Finished Product for sale
          or ultimate delivery within the other Party's Territory.

13.10     Each Party shall exercise its rights conferred under this Clause 13 as
          principal and it shall not sell or otherwise dispose of Finished
          Product on behalf of, or in the name of the other Party or any of its
          Affiliates.

13.11     Each Party shall not claim any agency or other relationship which
          indicates any authority to bind the other Party or its Affiliates
          contractually or incur liabilities on behalf of the other Party or its
          Affiliates.

14.       INTELLECTUAL PROPERTY - PROSECUTION, MAINTENANCE AND ENFORCEMENT

14.1      Columbia shall at its own cost and expense be solely responsible for
          the filing, prosecution and maintenance of the Columbia Patent Rights
          in the Ardana Territory, and shall use its reasonable efforts to
          prosecute all patent applications forming part of Columbia Patent
          Rights in all countries of the Ardana Territory, to the extent such
          Patent Rights are subject to the licenses granted Ardana in this
          Agreement (including the conduct of any disputes or proceedings
          relating to them including any opposition, reissue, re-examination, or
          proceedings). Columbia will take account of Ardana's interest
          hereunder when making any submission to a patent in relation to the
          Columbia Patent Rights in the Ardana Territory.

          14.1.1    In the event that Columbia declines to pay the official fee
                    to maintain any issued Columbia Patent Rights necessary to
                    maintain the licenses granted Ardana in the Ardana
                    Territory, Columbia shall provide Ardana with written notice
                    thereof prior to the expiration of any deadline relating to
                    such activities, but in any event at least twenty (20)
                    Business Days prior notice. In such circumstances Ardana
                    shall have the right to decide, with reason and with written
                    notice thereof at least five (5) Business Days prior to the
                    deadline, to require Columbia to pay such fee to maintain
                    such Columbia Patent Rights in Columbia's own name and
                    expense and Columbia shall do so.

             SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION.



          14.1.2    In the event that Columbia declines to file or, having
                    filed, declines to further prosecute and maintain any
                    pending Columbia Patent Rights necessary to maintain the
                    licenses granted Ardana in the Ardana Territory, Columbia
                    shall provide Ardana with written notice thereof prior to
                    the expiration of any deadline relating to such activities,
                    but in any event at least thirty-five (35) Business Days
                    prior notice. In such circumstances Ardana shall have the
                    right to decide, with reason and with written notice at
                    least thirty (30) Business Days prior to the deadline, that
                    Columbia should continue to file or prosecute such Columbia
                    Patent Rights. Columbia shall then have the option to
                    decide, with at least twenty (20) Business Days notice to
                    Ardana, to:

                    14.1.2.1  continue to file or prosecute such Columbia Patent
                              Rights in Columbia's own name and expense; or

                    14.1.2.2  allow Ardana reasonably to file or prosecute such
                              Columbia Patent Rights in Columbia's name and at
                              Columbia's reasonable expense using counsel of
                              Ardana's own choice, in which instance Ardana
                              shall invoice Columbia for such expenses within 30
                              days of the end of each Quarter, such invoice to
                              be payable within 30 days.

14.2      Each Party shall disclose to the other Party any invention arising
          pursuant to the Development Program, such disclosures to be provided
          within twenty (20) Business Days after the Party determines that an
          invention has been made. Such disclosures shall be treated as
          Confidential Information. The DC shall confirm, subject, if needed, to
          advice from each of Columbia's and Ardana's patent counsel, whether
          the invention falls within Columbia IP or Joint Program IP. If the
          invention falls within Columbia IP the provisions of Clause 14.1 shall
          then apply. If the invention falls within Joint Program IP, the DC
          shall decide, subject to advice from each of Columbia's and Ardana's
          patent counsel, whether to file for Patent Rights applications
          claiming such invention. In the event Patent Rights are not filed on
          such invention disclosures by either Party, such invention disclosures
          shall be considered Joint Program Know How. If the DC decides that a
          filing for Joint Program Patent

          Rights should be made Ardana shall during the period of the
          Development Program be the Responsible Party in relation to the
          preparation, filing, prosecution and maintenance of such Joint Program
          Patent Rights and for conducting any interferences, oppositions,
          reexaminations, reissues, revocations or requests for patent term or
          SPC extensions relating thereto, subject to Columbia's right to at
          least 30 days advance notice, with copies, of all proposed filings and
          proposed correspondence, as well as an opportunity for input regarding
          all such matters, and prompt copies of all actual filings and
          correspondence. Subject always to the provisions of Clause 8.3.4 all
          costs and expenses associated with such Joint Program Patent Rights
          incurred during the period of the Development Program shall be
          considered part of Development Costs. Thereafter and subject always to
          the provision of Clause 8.3.4 in the event of an Ardana Positive
          Election and a Columbia Positive Election Ardana shall be the
          Responsible Party in relation to the Ardana Territory and all costs
          and expenses incurred in relation to the Ardana Territory shall be the
          sole responsibility of Ardana and Columbia shall be the Responsible
          Party in relation to the Columbia Territory and all costs and expenses
          incurred in relation to the Columbia Territory shall be the sole
          responsibility of Columbia. The Responsible Party promptly shall
          provide copies of all correspondence with the respective patent office
          to the other Party and shall use reasonable efforts to keep the other
          Party informed of the progress of such prosecution. No filing for or
          Joint Program Patent Rights shall be abandoned by the Responsible
          Party unless both Parties have agreed to such action; otherwise, the
          abandoning Responsible Party will transfer the filing or Joint Program
          Patent Rights to the other Party, at the other Party's request.

14.3      If either Party learns of any infringement or threatened infringement
          by a Third Party of Columbia IP or Joint Program IP then such Party
          shall promptly notify the other Party and shall provide such other
          Party with available evidence of such infringement. In the case of
          Columbia learning of such infringement or threatened infringement of
          Columbia IP the obligation set out in this Clause 14.3 shall only
          apply where Columbia reasonably believes the infringement or
          threatened infringement to be relevant to Ardana's licenses pursuant
          to this Agreement.

14.4      In the event of an infringement of the Columbia Patent Rights (to the
          extent licensed to Ardana) and/or Joint Program IP by a third party in
          the Ardana Territory, Columbia

          shall have first right to bring any action or proceedings, and shall
          have sole control of the conduct of any such proceedings, including,
          the right to settle them, provided such settlement does not adversely
          affect Ardana's rights and interests within the Ardana Territory in
          accordance with the following:

          14.4.1    as an exclusive licensee to the Joint Program IP and to
                    certain portions of the Columbia Patent Rights in the Ardana
                    Territory, Ardana at its election shall have the right to be
                    joined as a co-plaintiff and to be separately represented by
                    counsel of its own choice and at its own cost and expense.
                    In such a situation, if Columbia and Ardana succeed in any
                    such proceedings in relation to an infringement in the
                    Ardana Territory, whether at trial or by way of settlement,
                    in obtaining a financial payment to Columbia and/or Ardana
                    with respect to the Joint Program IP or to the portion of
                    the Columbia Patent Rights licensed to Ardana:

                    14.4.1.1  Columbia shall first deduct for itself all of its
                              costs and expenses incurred in relation to such
                              proceedings; and

                    14.4.1.2  Ardana shall then be entitled for itself all of
                              its costs and expenses incurred in relation to
                              such proceedings; and

                    14.4.1.3  either if in such proceedings a court has
                              allocated damages to Columbia and Ardana
                              respectively each shall be entitled to retain such
                              damages within the Ardana Territory subject to the
                              provisions of sub-clauses 14.4.1.1 and 14.4.1.2
                              or, if in such proceedings a court has not so
                              allocated damages within the Ardana Territory the

                    Parties shall share such damages related to Ardana's
                    licenses [***], subject to the provisions of sub-clauses
                    14.4.1.1 and 14.4.1.2;

          14.4.2    If Ardana elects not to be joined as a co-plaintiff and not
                    to be separately represented, Ardana shall, at Columbia's
                    reasonable request and expense, provide Columbia with
                    reasonable assistance in relation to such action or
                    proceedings in the Ardana Territory. If Columbia succeeds in
                    any such proceedings in relation to an infringement in the
                    Ardana Territory, whether at trial or by way of settlement,
                    in obtaining a financial payment to Columbia, Columbia shall
                    first deduct for itself all of its costs and expenses
                    incurred in relation to such proceedings in the Ardana
                    Territory, and, in the event of any balance remaining in
                    relation to the Ardana Territory, [***] shall be allocated
                    to Columbia and [***] to Ardana;

          14.4.3    If Columbia fails to institute an action or proceeding in
                    relation to an infringement in the Ardana Territory for more
                    than ninety (90) days from becoming aware of the
                    infringement pursuant to this Clause 14.4 and if Ardana
                    wishes to do so, Ardana shall so notify Columbia and Ardana
                    shall have the right to do so and Columbia shall do all such
                    acts and things at Ardana's cost and expense as Ardana shall
                    reasonably request to assist Ardana in such proceedings,
                    including, lending its name to such proceedings. Ardana
                    shall have sole control of the conduct of any such
                    proceedings, including the right to settle them, provided
                    such settlement does not adversely affect Columbia's rights
                    and interests outside of the Ardana Territory, provided that
                    Columbia, at its election, shall have the right to be joined
                    as a co-plaintiff and to be separately represented by
                    counsel of its own choice and at its own cost and expense,
                    and the terms of Clauses 14.4.1 and 14.4.2 with regard to
                    Ardana shall be applicable to Columbia, provided that if
                    Columbia does not elect to join the proceeding as a
                    co-plaintiff, Ardana shall be entitled to retain [***] of
                    the damages in relation to the Ardana Territory. At Ardana's
                    reasonable request and expense, Columbia shall do all such
                    acts and things and sign all such documents as may be
                    necessary to give Ardana the full benefit of this Clause
                    14.4.3.

14.5      As of and after the Commencement Date on an ongoing basis, each Party
          shall have disclosed, and will promptly disclose to the other Party
          any Patent Rights owned by or licensed to the disclosing Party, other
          than Joint Program Patent Rights as well as any Third Party Patent
          Rights that are or become known to it that claim or disclose Candidate
          Product or Product, processes relating to the manufacture thereof or
          methods for their use, or otherwise are relevant to the collaboration
          established hereunder. In the event that any such Third Party Patent
          Rights are identified the cost of any freedom to operate searches and
          analyses with respect to Candidate Product and Products will be
          chargeable to Development Costs and the Parties will agree through the
          DC on an allocation of responsibilities between themselves regarding
          such searches and analyses.

14.6      Each Party shall promptly take all necessary steps to facilitate the
          other's application (made either on the other's own initiative or upon
          request by the first Party ) for extensions to the term of Columbia
          Patent Rights, and/or Joint Program IP in any country including
          applications for supplementary protection certificates and patent term
          extensions for the same in respect of Products. Each Party shall use
          its best efforts to obtain any and all such extensions to the extent
          permitted by law or regulation.

14.7      If during or after the Term of this Agreement, either Party receives
          any notice, claim or proceedings from any third party alleging
          infringement of that third party's intellectual property rights by
          reason of any Party's activities in relation to this Agreement, then:

          14.7.1    the Party receiving that notice shall forthwith notify the
                    other Party of the notice, claim or proceeding;

          14.7.2    neither Party shall make any admission of liability;

          14.7.3    the Parties shall consult with each other, taking advice
                    from their patent attorney as to whether they consider the
                    third party intellectual property infringed and if so
                    whether the claim of infringement is valid; and

          14.7.4    in the event that the Parties whose activities are accused
                    (the Accused Parties) consider that there is a genuine issue
                    of infringement of such third

                    party's intellectual property rights , the Parties shall
                    discuss in good faith whether to design around or to
                    challenge the same. If the Parties agree that it is not
                    possible or commercially reasonable to design around such
                    third party intellectual property, or cannot so agree, and,
                    nevertheless, agree to defend the incoming infringement
                    claim from the third party, the Accused Parties shall do so
                    using a single counsel to be jointly appointed by them at
                    their joint cost and expense, unless an Accused Party
                    reasonably believes that it is in its best interests to be
                    separately represented, in which case each Accused Party
                    shall be responsible for its own costs and expenses.
                    Alternatively, the Parties may agree to seek a license from
                    such third party in which case Columbia shall be responsible
                    for doing so. If Columbia does not itself require a license
                    to cover Columbia's activities, Columbia may choose to allow
                    Ardana to be responsible for seeking a license for itself.
                    If the Accused Parties can obtain a license upon terms
                    acceptable to each Party in its sole discretion, at that
                    time the Parties shall agree on any fees and royalties that
                    are necessary to obtain and maintain such a license which
                    shall be shared between the Parties in proportions which are
                    agreed between them in good faith which proportions are fair
                    and equitable between them reflecting the respective value
                    of the license to them, including without limitation whether
                    and the extent to which a Party's Territory is covered by
                    the license.

15.       WARRANTIES, INDEMNIFICATION; LIMITATION OF LIABILITY; AND INSURANCE

15.1      Each Party represents and warrants to the other Party that:

          15.1.1    it has the corporate power and authority and the legal right
                    to enter into this Agreement, to grant the licenses granted
                    and to enter into its other obligations, that it has taken
                    any necessary corporate action with Affiliates, and that
                    this Agreement is a legal and valid obligation binding upon
                    such Party and enforceable in accordance with its terms. The
                    execution, delivery and performance of the Agreement by such
                    Party does not conflict with any agreement, instrument or
                    understanding, oral or written, to which it is or by

                    court, governmental body or administrative or other agency
                    having jurisdiction over it;

          15.1.2    such Party has not, and during the term of the Agreement
                    will not, without the prior written consent of the other

                    conflict with the rights granted to the other Party

                    Patent Rights or other intellectual property rights of any
                    third party;

          15.1.4    it is a corporation duly organised, validly existing and in
                    good standing under the laws of the jurisdiction in which it
                    is incorporated; and

          15.1.5    the execution and delivery of this agreement and the
                    performance of such Party's obligations do not constitute a
                    default or require any consent under any other contractual
                    obligation of such Party.

15.2      EXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT COLUMBIA MAKES NO
          WARRANTIES OR REPRESENTATIONS, IMPLIED OR EXPRESS, WITH RESPECT TO THE
          PRODUCT OR ANY OF THE RIGHTS, LICENSES, OR ACTIVITIES GRANTED OR
          CONTEMPLATED HEREIN. SPECIFICALLY AND WITHOUT LIMITATION, COLUMBIA

          15.3.1    any Columbia activity related to the Candidate Product or
                    resulting Product after Ardana gives up its rights and
                    relevant activity pursuant to Clause 4.4, 5.4, or 18.4.1;

          15.3.2    that part of any claim brought against Ardana by a Third
                    Party which arises as a result of any activities of
                    Columbia, its Affiliates or contract manufacturers under or
                    in relation to this Agreement being a claim that use of any
                    Finished Product(s) has caused death or bodily injury; or

          15.3.3    a breach of warranty by Columbia under Clause 15.1.

          Clause 15.3 shall promptly notify Columbia of any Third Party claim in
          respect of which the Indemnified Party intends to claim that
          indemnification. The Indemnified Party shall not compromise or settle
          the claim prior to any such notice. Columbia may assume and control
          the defence of any such Third Party claim, provided however, that an
          Indemnified Party shall have the right to retain its own counsel at
          its own cost and expense, if representation of that Indemnified Party
          by the counsel retained by Columbia would be inappropriate due to
          actual or potential differing interests between the Indemnified Party
          and any other party represented by that counsel in the proceedings.
          The Indemnified Party shall co-operate with Columbia and its legal
          representatives in the investigation of any matter covered by this
          indemnification.

15.4      Subject to the provisions of Clause 15.5, Ardana shall be responsible
          for and shall indemnify Columbia and its Affiliates, directors,
          officers, servants and agents (collectively "the Indemnified Party")
          against any and all liability, loss, damage, cost and expense
          (including legal costs) incurred or suffered by the Indemnified Party:

          15.4.1    any Ardana activity related to the Candidate Product or
                    resulting Product after Columbia gives up its rights and
                    relevant activity pursuant to Clause 4.3, 5.4, or 18.5.1;

          15.4.2    as a result of that part of any claim brought against
                    Columbia or its Affiliates by a Third Party which arises as
                    a result of the activities by Ardana or its affiliates,
                    sublicensees, distributors or agents under this Agreement
                    being a claim that use of any Finished Products has caused
                    death or bodily injury; or

          15.4.3    as a result of a breach of warranty by Ardana under Clause

          An Indemnified Party that intends to claim indemnification under this
          Clause 15.4 shall promptly notify Ardana of any Third Party claim in
          respect of which the Indemnified Party intends to claim the
          indemnifications. The Indemnified Party shall not compromise or settle
          the claim prior to any such notice. Ardana may assume and control the
          defence of any such Third Party claim, provided however, that an
          Indemnified Party shall have the right to retain its own counsel at
          its own cost and expense, if representation of that Indemnified Party
          by the counsel retained by Ardana would be inappropriate due to actual
          or potential differing interests between the Indemnified Party and any
          other party represented by that counsel in the proceedings. The
          Indemnified Party shall co-operate with Ardana and its legal
          representatives in the investigation of ay matter covered by this
          indemnification.

15.5      Neither Party shall be liable to the other in contract, tort,
          negligence, breach of statutory duty or otherwise for any loss,
          damage, costs or expenses of any nature whatsoever incurred or
          suffered by the other or its Affiliates:

15.6      Columbia shall secure and maintain comprehensive general liability
          insurance with insurers having an AM Best rating within the top 2
          categories at the time (at the date of this Agreement known as
          "superior" or "excellent"), including, product liability, contractual
          liability, personal injury, and insurance against claims regarding the
          development, manufacture, delivery, storage, handling and use of

          prudent insurance practice, but in no event less than the US dollar
          equivalent of [***] pounds sterling (GB(pound)[***]) per occurrence

          15.7 during the term of this Agreement and thereafter for so long as

          third parties nor to use the Confidential Information except to the

          Information shall not be subject to the restrictions and prohibitions
          set forth in this Clause 16 to the extent that such Confidential
          Information:

          16.1.1    is available to the public in public literature or
                    otherwise, or after disclosure by one Party to the other

                    provisions to keep confidential as many terms of this
                    Agreement as possible.

16.4      In respect of those public announcements and disclosures not permitted
          by Clause 16.3 the Party desiring to make any such public announcement

                    Clause 8. In the event that in any country such a transfer
                    is not possible, the Ardana shall use reasonable endeavours
                    to ensure that Columbia has the benefit of the relevant
                    Regulatory Approvals, Marketing Authorisations, Regulatory
                    applications and other regulatory filings and approvals and,
                    to this end, consents to any Governmental Authority
                    cross-referencing to the data and information on file with

                    Know How comprised in the Joint Program IP and all copies
                    made (save for a single copy to be retained for evidential
                    purposes by Columbia's lawyers) and any other Know How held
                    by Columbia relating to the Candidate Product and/or the
                    resultant Product;

          18.5.3    Columbia shall not use or otherwise exploit in any way,
                    either directly or indirectly the Joint Program IP with
                    regard to the Candidate Product or resultant Product in

          18.5.4    Ardana shall be free to use and exploit all Joint Program IP

                    thereof;

          18.5.5    Ardana shall have the option, on a case by case basis, to
                    assume sole responsibility for the prosecution, maintenance,
                    defence and enforcement of Joint Program IP at its own cost
                    and expense, though Columbia shall retain joint ownership

                    to the Candidate Product or resulting Product in either case
                    in relation to all indications;

          18.5.6    if Columbia has entered into a Manufacturing and Supply
                    Agreement this may at Ardana's option exercisable on 90 days

                    date of termination either continue or be terminated and if
                    Ardana exercises its rights to terminate the Manufacturing
                    and Supply Agreement, Columbia will at its own cost and
                    expense provide such reasonable technical and other
                    assistance as may be required in order to ensure that Ardana

                    ROW Territory in relation to which Columbia has been
                    appointed the Responsible Party pursuant to Clause 8. In the

                    to apply.

18.6      Termination of this Agreement (whether under this Clause 18, upon
          expiration of the Term, or otherwise) shall be without prejudice to
          any rights of either Party against the other that may have accrued to
          the date of such termination.

19.       FORCE MAJEURE

19.1      The obligations of the either Party hereunder shall be suspended

          complying therewith due to Force Majeure.

          circumstance, the Party so affected shall furnish to the other Party
          all particulars of the Force Majeure and the manner in which its
          performance is thereby prevented or delayed. The Party whose
          obligations hereunder have been suspended shall promptly and
          diligently pursue appropriate action to enable it to lift the Force
          Majeure situation, except that a Party shall not be obligated to
          settle any strike, lockout or other labor difficulty on terms contrary
          to its wishes.

20.       GENERAL PROVISIONS

20.1      Independent Contractors. Ardana and Columbia are independent of each
          other and nothing contained herein shall be construed to create a
          joint venture, partnership or similar relationship. Neither Party is
          authorized to, nor shall it, incur any liability whatsoever for which
          the other may become directly, indirectly or contingently liable.

20.2      Dispute Resolution; Consent to Jurisdiction. This Agreement shall be
          construed and interpreted in accordance with the law of the State of
          Delaware without regard to principles related to conflicts of laws.
          The parties expressly agree that the United Nations Convention on
          Contracts for the International Sale of Goods shall not apply to the
          interpretation and construction of this Agreement. In an effort to
          resolve informally and amicably any claim, controversy or dispute
          (whether such claim, sounds in contract, tort, or otherwise) arising
          out of or relating to this Agreement, or the breach thereof (a
          "Dispute"), each Party shall notify the other in writing of a Dispute
          hereunder that requires resolution. Such notice shall set forth the
          nature of the Dispute, the amount, if any, involved and the remedy
          sought. Each Party shall designate a representative who shall be
          empowered to investigate, discuss and seek to settle the Dispute. If
          the two representatives are unable to settle the Dispute within thirty
          (30) days after proper notification, the Dispute shall be submitted to
          the Chief Executive Officer of each Party for consideration for an
          additional thirty (30) days. If

          the Dispute remains unresolved after said sixty (60) day period,
          either Party shall have a right to commence any action, suit or
          proceeding with respect to such Dispute in a U.S. federal court of
          competent jurisdiction in Delaware. The venue for such action, suit or
          proceeding shall be in the U.S. federal Courts in Delaware. No
          provision of, or the exercise of any rights under, this Agreement
          shall limit the right of the parties to obtain, apply for, or resort
          to court ordered injunctive relief. Ardana and Columbia each further
          irrevocably consent to the service of any complaint, summons, notice
          or other process by delivery thereof to it by any manner in which
          notices may be given pursuant to this Agreement.

                    in accordance with Clause 20.3.3. Notices sent by hand or by
                    courier shall require a written receipt of delivery. Notices
                    sent by fax or E-Mail shall not be valid of themselves and
                    must be confirmed in hard copy form by hand or by recorded
                    delivery.

          20.3.2    Any notice given pursuant to this Clause shall be deemed to

                              on which the change is to take place; or

                              less than (five) clear Business Days after the

                              falling five clear Business Days after notice of
                              any such change has been given.

20.4      Assignment. Columbia shall not assign this Agreement without also
          assigning to the same assignee the relevant portions of the Columbia
          IP and its interest in the Joint Program IP and all related Regulatory
          Application and Regulatory Approvals the subject matter of this
          Agreement and conversely may not assign the rights in the relevant
          portion of the Columbia IP and in its interest in the Joint Program IP
          and all related Regulatory Applications and Regulatory Approvals the
          subject matter of this Agreement and Trade Marks (other than to an
          Affiliate) without also assigning to the same assignee this Agreement.
          Ardana shall not assign this Agreement without also assigning to the
          same assignee its rights in the Joint Program IP and all related
          Regulatory Applications and Marketing Authorisations the subject
          matter of this Agreement and conversely may not assign its rights in
          the Joint Program IP and all related Regulatory Applications and
          Marketing Authorizations the subject matter of this Agreement (other
          than to an Affiliate) without also assigning to the same assignee this
          Agreement. This Agreement shall not be assignable by either Ardana on
          the one hand or by Columbia on the other hand ("Assignor") without the
          written consent of the other ("Remaining Party") such consent not to
          be unreasonably withheld, provided however that either Party may
          assign this Agreement to any Affiliate or to a corporation with which
          such Party may merge or consolidate, or to which it may transfer all
          or substantially all of its assets to which this Agreement relates,

          may be amended, modified, superseded or cancelled, and any other of
          the terms or conditions hereof may be modified, only by a written
          instrument executed by both parties hereto or, in the case of a
          waiver, by the Party waiving compliance. Failure of any Party at any
          time or times to require performance of any provision hereof shall in
          no manner affect the right of such Party at a later time to enforce
          the same, and no waiver of any nature, whether by conduct or
          otherwise, in any one or more instances, shall be

                                       73

          deemed to be or considered as a further or continuing waiver of any
          other provision of this Agreement.

20.6      Severability. In the event that any one or more of the agreements,
          provisions or terms contained herein shall be declared invalid,
          illegal or unenforceable in any respect, the validity of the remaining
          agreements, provisions of terms contained herein shall in no way be
          affected, prejudiced or invalidated thereby.

20.7      Entire Agreement. This Agreement, together with the Exhibits hereto,
          contains the entire agreement between the parties hereto and

          counterparts, each of which shall be deemed to be an original, but

21.       MIPHARM AGREEMENT AND TESTOSTERONE FOR WOMEN

21.1      The Parties recognize the existence of, and that this Agreement is
          subject to, a license and supply agreement made between Bermuda and
          Mipharm SpA ("Mipharm") dated 5 March 1999 (the "Mipharm Agreement"),
          a copy of which is attached hereto as Exhibit F.

21.2      From the Commencement Date and up to the elections by the Parties
          under Clause 4.1, or such other date as the Parties may agree in
          writing, Columbia shall, consistent with Good Industry Practice, take
          all commercially reasonable acts to remove Chronodyne(R) (terbutaline
          gel) from the grant of the license to Mipharm under the Mipharm
          Agreement, such that the Mipharm Agreement does not affect the

          Agreement does not affect the Candidate Product or resultant Product,
          this Agreement shall be deemed to be amended to add Greece, Ireland,
          Italy (including San Marino and Vatican City), and Portugal to the
          definition of Europe. When undertaking its obligations under this
          Clause 21.2 Columbia shall regularly liaise with Ardana and Ardana
          shall, insofar as it communicates with Mipharm about the removal of
          Chronodyne (terbutaline gel) from the grant of the license to MiPharm,
          regularly liaise with Columbia. [***]
