Fair, Isaac Names e-Business Pioneer Thomas Grudnowski CEO


SAN RAFAEL, CALIFORNIA--September 8, 1999--Fair, Isaac and Company, Incorporated
(NYSE:  FIC) today announced that Thomas G. Grudnowski will become the company's
president  and chief  executive  officer,  and a member of its Board,  effective
December  2, 1999,  after  transitioning  from his current  responsibilities  at
Andersen Consulting. Grudnowski, 49, is currently the managing partner in charge
of Andersen's line-of-business e-commerce ventures.

As announced earlier this year, the company's current CEO, Larry E. Rosenberger,
will  continue  to  lead  Fair,   Isaac's  research  and  development   efforts,
company-wide.   Rosenberger  was  in  charge  of  the  company's   research  and
development unit earlier in his career and added responsibility for this area to
his duties as CEO in March.

Since 1994,  Grudnowski's  responsibilities  have focused on the  development of
electronic commerce businesses serving a wide variety of industries.  He led the
creation  of  several  Andersen  Consulting  strategic   initiatives   including
net-centric  computing,  industry  solutions  centers,  netsourcing,  and,  most
recently,   Andersen's  efforts  to  create  spin-out   e-commerce   businesses.
Grudnowski  launched and served in the role of CEO of four different  e-business
companies started under Andersen's  auspices.  Prior to 1994 he was the managing
partner  of  Andersen's   Minneapolis  region  Services  Industries  Group  with
responsibility   for   assignments  in  the  financial   services,   healthcare,
telecommunications,  transportation,  utility and government  sectors. A partner
since 1983,  Grudnowski  joined Andersen  Consulting in 1972. He holds a B.S. in
mathematics  and  accounting  from  St.  John's   University  in   Collegeville,
Minnesota.

Fair, Isaac chairman Robert M. Oliver said, "Tom Grudnowski was the overwhelming
choice of the search  committee,  and we are  delighted  that he is joining  the
Fair,  Isaac team. He has  experience  in all of the  industries we are actively
pursuing.  We were especially  impressed by Tom's proven ability to successfully
launch a number of  e-business  start-ups,  and  we're  looking  forward  to his
contributions."   Mr.  Oliver  continued,   "The  Board  is  grateful  to  Larry
Rosenberger  for his  leadership  over the past eight  years,  which  fueled our
growth from $25 million in  revenues to more than $250  million,  and we're very
pleased that he will be leading our research and  development  activities  going
forward."

Mr.  Grudnowski said, "I'm very excited by the prospect of helping to lead Fair,
Isaac into the 21st century. The same data-driven decision technologies that the
company pioneered in consumer credit have virtually  unlimited potential in many
other markets,  especially the rapidly expanding world of electronic commerce. I
think the new strategic plan  announced by the company  earlier this year can be
the blueprint for delivering greater value to an expanded client base, increased
opportunities  to  Fair,   Isaac's   employees  and  long-term  rewards  to  its
stockholders.  I'm looking  forward to working with the rest of the Fair,  Isaac
leadership team to make this great company even greater."
