Exhibit 10.22



October 29, 1997

Mr. A.J. Berkeley
Interlink Computer Sciences

Dear A.J.,

On behalf of the Company's  shareholders,  employees and Board of Directors,  it
gives me great  pleasure  to offer  you the  position  of  President  and  Chief
Executive Officer.

Allow me to review  the terms of the offer:  as  President  and Chief  Executive
Officer,  your base salary will be $270,000  annually  payable  according to the
Company's  standard  payroll  process.  You are  eligible  to  receive  up to an
additional  $130,000 based on attainment of individual  objectives which will be
mutually  agreed  upon  between  you and the  Board.  These  objectives  will be
finalized within the first 30 days of your assuming the position.

You will also been granted 151,150 stock options (grant and initial vesting date
effective October 1, 1997) according to the terms of the Company's 1992 Employee
Stock Option Plan.

In addition,  you have been granted a performance based stock option totaling an
additional  151,150  options.  These  options  are to vest over a seven (7) year
period.  According  to the terms of this grant,  if the  average  share price in
effect on October 1, 1997 doubles and the  increased  price is sustained  over a
one month period,  your performance  based options will accelerate their vesting
by one year. Thereafter, an additional year of vesting will accelerate for every
$5 of incremental  value added to the Company's  average  stock.  The stock must
retain its increased value over a one month period in order for any acceleration
of options to occur.  The  performance  based option grant will carry a two year
minimum vesting schedule regardless of acceleration factors.

In addition,  the Company will provide financial  coverage for up to 1/2 of your
personal  investment in your previous  business  venture.  The total anticipated
cost to the Company is limited to a maximum of $75,000.

Finally,  as President and Chief Executive  Officer,  you will receive up to one
year of severance  pay if you should  involuntarily  lose your  position for any
reason other than for Cause.

For all purposes under this Agreement,
     "Cause"  shall mean (i)  willful  failure by the  Executive  to perform his
     duties  hereunder,  (ii) a willful act by the Executive  which  constitutes
     gross  misconduct  and which is injurious  to the Company,  (iii) a willful
     breach by the Executive of a material provision of this Agreement,  or (iv)
     a material  violation  of a federal,  state or

                                       41

     foreign law or regulation applicable to the business of the Company. No act
     or failure to act by the  Executive  shall be considered  "willful"  unless
     committed without good faith or without a reasonable belief that the act or
     omission was in the Company's best interest.

AJ, I am delighted that you have chosen to stay at Interlink and believe that we
have many good things ahead of us. Congratulations!




Sincerely,


Tom Bredt
Chairman of the Board
