2.1      Grant of Option. The School of Pharmacy hereby grants to Somantis the
         right to purchase and acquire the Patents in accordance with Clause
         8.1.

2.2      Assignment and Licence. On the Option Exercise Date subject to the
         provisions of this Agreement, The School of Pharmacy shall:

3.       Know-how and Confidential Information

3.1      Provision of Know-how. Upon Somantis' reasonable request, The School of
         Pharmacy shall supply Somantis with all Know-how in its possession that
         The School of Pharmacy is at liberty to disclose and has not previously
         been disclosed and which is reasonably necessary or desirable to enable
         Somantis to undertake the further development of the Royalty-bearing
         Products. The Know-how shall be subject to the confidentiality
         provisions of Clause 3.4 and The School of Pharmacy shall be bound by
         such provisions as if the Know-how had been developed by Somantis and
         disclosed to The School of Pharmacy hereunder. If it is agreed that any
         representative of The School of Pharmacy shall travel to Somantis'
         premises in connection with such supply, Somantis shall reimburse all
         travel (at business class rates), accommodation and subsistence costs
         incurred.

3.2      Status of Know-how. Somantis acknowledges that the Know-how is at an
         early stage of development. Accordingly, specific results cannot be
         guaranteed and any results, materials, information or other items
         (together "Delivered Items") provided under this Agreement are provided
         "as is" and without any express or implied warranties, representations
         or undertakings. As examples, but without limiting the foregoing, The
         School of Pharmacy does not give any warranty that Delivered Items do
         not infringe third party rights, are of merchantable or satisfactory
         quality, are fit for any particular purpose, comply with any sample or
         description, or are viable, uncontaminated, safe or non-toxic.

3.3      Responsibility for development of Royalty-bearing Products. Somantis
         shall be exclusively responsible for the technical and commercial
         development and manufacture of Royalty-bearing Products and for
         incorporating any modifications or developments thereto that may be
         necessary or desirable and for all Royalty-bearing Products sold or
         supplied, and accordingly Somantis shall indemnify The School of
         Pharmacy in the terms of Clause 7.4.

3.4      Confidentiality obligations. Subject to the terms of this Agreement,
         each Party ("Receiving Party") undertakes:

         (a)      to maintain as secret and confidential all Know-how and other
                  technical or commercial information obtained directly or
                  indirectly from the other Party ("Disclosing Party") in the
                  course of or in anticipation of this Agreement and to respect
                  the Disclosing Party's rights therein,

         (b)      to use the same exclusively for the purposes of this
                  Agreement, and

         (c)      to disclose the same only to those of its employees,
                  contractors and licensees or sublicensees pursuant to this
                  Agreement (if any) to whom and to the extent that such
                  disclosure is reasonably necessary for the purposes of this
                  Agreement.

3.5      Exceptions to obligations. The provisions of Clause 3.4 shall not apply
         to Know-how and other information which the Receiving Party can
         demonstrate by reasonable, written evidence:

         (b)      is subsequently disclosed to the Receiving Party without any
                  obligations of confidence by a third party who has not derived
                  it directly or indirectly from the Disclosing Party; or

         (c)      is or becomes generally available to the public through no act
                  or default of the Receiving Party or its agents, employees,

                  any competent jurisdiction, or to any government regulatory
                  agency or financial authority, provided that the Receiving
                  Party shall (i) inform the Disclosing Party as soon as is
                  reasonably practicable, and (ii) at the Disclosing Party's
                  request seek to persuade the court, agency or authority to
                  have the information treated in a confidential manner, where
                  this is possible under the court, agency or authority's
                  procedures; or

         (e)      in the case of information disclosed by The School of Pharmacy
                  to Somantis, is disclosed to actual or potential customers for
                  Royalty-bearing Products in so far as such disclosure is
                  reasonably necessary to promote the sale or use of
                  Royalty-bearing Products, provided that the customers sign a
                  written confidentiality undertaking at least as restrictive as
                  Clauses 3.4 and 3.5.


3.6      Disclosure to employees. The Receiving Party shall procure that all of
         its employees, contractors and licensees or sub-licensees pursuant to
         this Agreement (if any) who have access to any of the Disclosing
         Party's information to which Clause 3.4 applies, shall be made aware of
         and subject to these obligations and shall have entered into written
         undertakings of confidentiality at least as restrictive as Clauses 3.4
         and 3.5 and which apply to the Disclosing Party's information.

3.7      Right to Publish Notwithstanding the provisions of Clause 3.4, The
         School of Pharmacy shall have the right to use, publish and present the
         Patents and Know-how for academic and research purposes (irrespective
         of applications). The School of Pharmacy will use reasonable endeavours
         to submit material intended for publication which relates to the
         Patents or the Know-how to Somantis in writing not less than thirty
         (30) days in advance of the submission for publication. Somantis may
         request that submission for publication be delayed if Somantis
         reasonably believes that the intended publication would materially
         damage its commercial interests (such as, without limitation, the
         protection of confidential information or the filing of patent
         applications). A delay imposed on submission for publication as a
         result of a request made by Somantis shall not exceed sixty (60) days
         from the date of receipt of the material by Somantis. Notification of
         the request for delay in submission for publication must be received by
         The School of Pharmacy within fourteen (14) days after the receipt of
         the material by Somantis, failing which The School of Pharmacy shall be
         free to assume that Somantis has no objection to the proposed

         manner use its best endeavours to secure from the proper authority in
         the relevant country permission to make the said payments and will make
         them within 7 days of receiving such permission. If such permission is

6.3.2    If the Parties fail to agree on a joint programme of action, including
         how the costs of any such action are to be borne and how any damages or
