              Fair, Isaac Expects Higher Revenue But Flat Earnings

December 16, 1997


San Rafael,  Calif.--Fair,  Isaac and Company,  Inc. (NYSE: FIC) today announced
that, while it expects healthy revenue growth in the quarter ending December 31,
1997, compared with the same period a year ago, the company anticipates that its
operating margin will be lower than in the December 1996 quarter.  President and
CEO Larry E. Rosenberger said he believes the percentage  growth in revenues for
the quarter,  over the same period a year ago, will be in the "mid-twenties" but
that the company's  operating expenses are growing even faster. As a result, the
company  expects  that  operating  income and earnings per share for the current
quarter will be approximately even with the same quarter a year ago.

Rosenberger  noted,  "A number of factors are putting  pressure on our operating
margin  right now.  Our  internal  forecast  had called for even higher  revenue
growth  early in the  1998  fiscal  year,  so we  authorized  hiring  and  other
expenditures  accordingly.  However,  the  continuing  wave of bank  mergers has
resulted in the  cancellation of some orders and has delayed other projects.  In
addition,  the internal systems staffs of many of our clients are preoccupied by
`Year  2000'  issues and are thus unable to provide  the  assistance  we need to
complete--and  sometimes to start--our work.  Finally,  we remain constrained by
staffing shortages in certain areas.

"On the expense side, some units are still finding it necessary to use expensive
contract  labor to meet  current  demand  from our  clients  while  keeping  the
development  of new  products on schedule.  While we have made some  progress in
recent months in recruiting  additional  permanent  staff, it takes some time to
get newly hired employees to the point where they are fully productive.  We have
also chosen to expend  resources in pursuing new product and market  development
opportunities  which we believe have great future  potential--but  which are not
yet producing revenue."

                                   -- more --





Mr.  Rosenberger  concluded  by  saying,  "Fundamentally,  the  demand for Fair,
Isaac's  products and services  remains  strong.  The current  margin squeeze is
mostly a case of 'growing pains', and we believe it will be temporary.  Where we
can cut costs without sacrificing  long-term growth and profitability we will do
so, but we are  determined  to manage the  company for the long haul rather than
just quarter-to-quarter results."
