Dear Melinda,

This Employment Agreement records your employment with Synon Research Limited

September 1992.

1.       Duties and place of work

1.1      The Company shall employ you as Director of Development or in any
         other capacity as the Company may agree with you from time to time.
         You will be a Director of the Company.  You will be required to work
         at 91 St Pauls Road, London N1 2YU, or in the event of the Company or
         any of its subsidiary or associated companies no longer occupying that
         address at such other address within a three mile radius of that
         address that the Company may agree with you from time to time.  You
         may be required to travel on the business of the Company or any of its
         subsidiary or associated companies anywhere in the world (as the same
         are defined in Section 736 of the Companies Act 1985 and Section 416
         of the Income and Corporation Taxes Act 1988, respectively).  You are
         to report to the Chief Technology Officer of Synon Corporation.

1.2      You shall devote the whole of your time and attention during working
         hours to the interests and welfare of the Company and its subsidiary
         and associated companies and faithfully and diligently perform your
         duties to de best of your ability.  You may be required in pursuance
         of your duties to perform services not only for the Company but also
         for any subsidiary or associated company.

1.3      You will not during the term of your employment hereunder be directly
         or indirectly concerned, engaged or interested in any business
         competing with that of the Company except with the written consent of
         the Board of Directors of the Company, or as the holder (directly or
         through nominees) of investments listed on any recognised stock
         exchange where the holding does not exceed five per cent of the issued
         shares or stock of any class of any one company.

1.4      Under an Employment Agreement of even date between the Company and
         Simon Williams, the Company has authorised Simon Williams to employ
         and direct on its behalf a Development Team located at your place of
         work, which you shall manage.  The said Development Team may comprise,
         at Simon Williams' sole discretion, up to seventeen (17) people
         (including yourself) of appropriate skills and experience, employed at
         salaries and under terms and conditions commensurate with those that
         prevail in similar software research and development organisations
         within the London area.  The Development Team will be engaged upon
         such software product research and development projects as Synon
         Corporation shall determine from time to time.  It is a condition of
         your employment that Simon Williams is Chief Technology Officer of
         Synon Corporation and that the Company shall continue to authorise
         Simon Williams to employ the Development Team on its behalf under the
         terms and conditions set out in this clause 1.4.

                          breach of this Employment Agreement;

                 then the said rate of Commission shall not be so reduced.  The
                 references to "Preferred Stock", "Common Stock" and
                 "Conversion Price" in this clause 2.5.ii shall have the

         plant, machinery, processes or formulae of the Company or any
         subsidiary or associated company or any customer of the Company or of
         any subsidiary or associated company.  This restriction shall cease to

         may evolve, discover, invent or improve at any time during the course
         of or arising out of your employment with the Company, including any
         of the said procedures or inventions which result from disclosures to
         you by any customer of his own procedures, inventions or machinery

         necessary to secure and where appropriate to register in the name of
         the Company or the customer as the case may be any letters patent,
         copyrights and/or trade marks in the United Kingdom and elsewhere in
         respect of the said procedures and inventions.

         other, or in the absence of notice the date of actual termination of
         your employment.
