Dear Kevin:

Based on our  conversation  of  today,  Cognigen  acknowledges  the need for and
requests   your   support   in   the   areas   of   expanded    consulting   and
technical/administrative services. The services to be performed and supported by
you included but may not be specifically limited to:

1)   Dealing with spam-related issues.

2)   Participating  in website issues  relating to server  performance,  product
     launch, truth in advertising, spelling, grammar, etc.

3)   Dealing with web competitive/copyright infringement issues.

4)   Ameliorating server related emergencies (7x24).

5)   Advising Bill Beason on commission related issues.

6)   Answering  calls and  email  from  Cognigen  staff on  "critical"  tactical
     issues.

7)   Participating in company and product development, meetings/conference calls
     (InTandem, etc.)

8)   Additional activity as agreed to in advance by both parties.

For your support in these areas, Cognigen will pay you a fee of $4,000 per month
covering  your time  through  December  31,  2003.  The $4,000 is an increase of
$3,000 to your current $1,000 Kevin E. Anderson consulting  agreement within the
Cantara  contract.  Additionally,  Cognigen will continue to support the expense
associated with your Internet T-1 connection (approximately $700 per month).

The work you have  performed for the months of January and February 2003 will be
paid at $3,000  additional  dollars per month ($6,000 total). A check for $6,000
will be cut by 3-15-03.

With the  concurrence,  this agreement  will become  effective  immediately  and
continue through 12-31-2003.


By                                        Agreed to by
