below) at any time, or within six months following a Change of Control
("Termination Following Change of Control") Inventa will:

     date of termination, or, if sooner, until the date you obtain other full-

B.   Pay all costs which Inventa would otherwise have incurred to maintain all
     of your health and welfare, and retirement benefits (either on the same, or
     substantially equivalent terms and conditions) if you had continued to

     termination of employment, or, if sooner, until you obtain other full-time
     employment; and

C.   Permit options granted to you which have not then vested to continue to
     vest in accordance with their stated vesting schedule(s) during the six
     month period after the date of termination, and to be exercisable during
     such six month period to the extent vested, including any options which
     would not otherwise have been exercisable during the first year after grant
     of such options.

During the period when such severance compensation is being paid to you, you
agree not to (i) engage, directly or indirectly, in providing services to any
other business, program or project that is competitive to a business, program or
project being conducted by Inventa or any affiliate of Inventa at the time of
such employment termination, or (ii) solicit, or attempt to solicit on behalf of
yourself or any other party, any employee or exclusive consultant of Inventa.

will be included as a participant in that plan and its terms will supersede the
"Termination Following Change of Control" provisions in this letter.

             fraud, theft or embezzlement or any other felony,
     (ii)    has failed or refused in any material respect, to follow reasonable
             written policies or directives established by the Board of
             Directors,
     (iii)   has willfully and persistently failed to attend to material duties
             or obligations imposed on him under this agreement, or
     (iv)    has performed or failed to act, which if he were prosecuted and
             convicted would constitute a crime or offense involving money or
             property of the Company (in either case in an amount or at a value
             in excess of $1,000), or which would constitute a felony in the
