Item 6. Resignations of Registrant's Directors. On April 23, 2001, the Registrant received a letter from Robert D. Sanderson, one of the Registrant's directors, a copy of which is attached hereto as Exhibit 17.1. In his letter, Dr. Sanderson resigned as a director of Registrant effective April 23, 2001 and stated his disagreement with a proposal that Registrant's Board of Directors grant Thomas G. Grudnowski, Registrant's Chief Executive Officer, the option to purchase 50,000 shares of Registrant's common stock outside of Registrant's 1992 Long-term Incentive Plan. The proposed options were in addition to 50,000 options granted to Mr. Grudnowski under the Registrant's 1992 Long-term Incentive Plan. The proposed options would vest over a 4-year period and be exercisable at the fair market value of the common stock on the date of grant. The proposed option grant was approved on May 1, 2001 by each of Registrant's remaining directors, with Mr. Grudnowski abstaining, after the proposed grant was unanimously recommended by Registrant's Compensation Committee. The Compensation Committee based its recommendation on, among other factors, a review of Mr. Grudnowski's performance over the past year and the compensation of other similarly situated chief executive officers.

Dr. Robert M. Oliver, Chairman
Fair, Isaac & Co., Inc.
200 Smith Ranch Road
San Rafael, CA  94903

Dear Dr. Oliver:

I hereby resign as a Director of Fair, Isaac effective immediately.

I am resigning  because I disagree with the rest of the Board's  willingness  to
grant  100,000  stock  options to Tom  Grudnowski  in fiscal  2001.  This was an
incorrect decision for two principal reasons.

First, the Company's 1992 Long-Term  Incentive Plan limits the number of options
which may be granted to any one employee to 50,000 a year. While it may be legal
to grant Mr.  Grudnowski  100,000 options,  doing so would violate the spirit of
the agreement among the Company, the Board and the shareholders  embodied in the
plan.

Second,  Mr.  Grudnowski  doesn't  deserve  the  grant.  He was hired to get the
Company  growing again and to develop  Internet-based  new business.  During his
tenure as CEO revenue growth has been below the Company's  long-term record, and
revenues from new business have been miniscule.  He has not earned the reward of
an extraordinary option grant.

It is my hope that the Board will conclude, as I have, that the Company will not
achieve long-term success with Mr. Grudnowski in charge and that the best way to
increase shareholder value is to sell the Company.

Sincerely,



Robert D. Sanderson
