                             STOCK OPTION AGREEMENT
                                FEBRUARY 5, 2002
                             (FOR A. GEORGE BATTLE)

NONSTATUTORY
STOCK OPTION                      This option is not intended to qualify as an
                                  incentive stock option under Section 422 of
                                  the Internal Revenue Code.

VESTING                           Your entire option is 100% vested and
                                  exercisable in full at all times.


TERM                              Your option will expire at the close of
                                  business at Fair, Isaac and Company,
                                  Incorporated ("Fair, Isaac") headquarters on
                                  the earlier of (a) the Expiration Date shown
                                  on the Notice of Grant of Stock Options and
                                  Options Agreement ("Option Agreement,) or (b)
                                  12 months after the date on which your
                                  service, whether as a non-employee director,
                                  consultant or employee with Fair, Isaac
                                  terminates.

                                  Fair, Isaac determines when your service
                                  terminates for this purpose.

RESTRICTIONS ON
EXERCISE                          You agree not to exercise this option if the
                                  issuance of shares at that time would violate
                                  any law or regulation, as determined by Fair,
                                  Isaac. Moreover, you cannot exercise this
                                  option unless you have returned a signed copy
                                  of the Option Agreement to Fair, Isaac.

NOTICE OF EXERCISE                When you wish to exercise this option, you
                                  must notify Fair, Isaac by filing Fair,
                                  Isaac's "Notice of Exercise" form at the
                                  address given on the form. The notice will be
                                  effective when it is received by Fair, Isaac.
                                  If your notice was sent by facsimile
                                  transmission, it will be effective only if it
                                  is promptly confirmed by filing a form with an
                                  original signature.

                                  Your notice must specify how many shares you
                                  wish to purchase. Your notice must also
                                  specify how your shares should be registered
                                  (in your name only or in your and your
                                  spouse's names as community property or as
                                  joint tenants with right of survivorship).

                                  If someone else wants to exercise this option
                                  after your death, that person must prove to
                                  Fair, Isaac's satisfaction that he or she is
                                  entitled to do so.

                                  must include payment of the exercise price for

                                           Isaac to sell your option shares and

                                           balance of the sale proceeds, if any,
                                           will be delivered to you via your
                                           broker.) The directions must be given
                                           by signing a special "Notice of
                                           Exercise" form provided by Fair,
                                           Isaac.

                                        -  Certificates for Fair, Isaac stock
                                           that you have owned for at least 12

                                           to effect a transfer of the shares to
                                           Fair, Isaac. The value of the shares,
                                           determined as of the effective date
                                           of the option exercise, will be
                                           applied to the exercise price.

WITHHOLDING TAXES                 Fair, Isaac will not withhold taxes on stock
                                  option exercises made by non-employee
                                  directors.

RESTRICTIONS ON RESALE            By signing the Option Agreement, you agree not
                                  to sell any shares at a time when applicable
                                  laws or Fair, Isaac policies prohibit a sale.
                                  This restriction will apply as long as you are
                                  a non-employee director of Fair, Isaac (or a
                                  subsidiary).

TRANSFER OF OPTION                Prior to your death, only you or a permitted
                                  assignee as defined herein may exercise this
                                  option (unless this option or a portion
                                  thereof has been transferred to your former
                                  spouse by a domestic relations order by a
                                  court of competent jurisdiction). You may
                                  transfer this option or a portion of this
                                  option by gift to members of your immediate
                                  family, a partnership consisting solely of you
                                  and/or members of your immediate family, or to
                                  a trust established for the benefit of you
                                  and/or members of your immediate family
                                  (including a charitable remainder trust whose
                                  income beneficiaries consist solely of such
                                  persons). For purposes of the foregoing,
                                  "immediate family" means your spouse, children
                                  or grandchildren, including step-children or
                                  step-grandchildren. Any of these persons is a
                                  "permitted assignee." However, such transfer
                                  shall not be effective until you have
                                  delivered to Fair, Isaac notice of such
                                  transfer. You cannot otherwise transfer or
                                  assign this option. For instance, you may not
                                  sell this option or use it as security for a
                                  loan. If you attempt to do any of these
                                  things, this option will immediately become
                                  invalid. You may, however, dispose of this
                                  option in your will or by a written
                                  beneficiary designation. Such a designation
                                  must be filed with Fair, Isaac on the proper
                                  form and will be recognized only if it is
                                  received at Fair, Isaac headquarters before
                                  your death.

RETENTION RIGHTS                  Neither the Option Agreement nor the terms of
                                  this Agreement give you the right to be
                                  retained by Fair, Isaac (or any subsidiaries)
                                  in any capacity.

STOCKHOLDER RIGHTS                You, or your estate, beneficiaries or heirs,
                                  have no rights as a stockholder of Fair, Isaac
                                  until a certificate for your option shares has
                                  been issued. No adjustments are made for
                                  dividends or other rights if the applicable
                                  record date occurs before your stock
                                  certificate is issued, except as otherwise
                                  described herein.

ADJUSTMENTS                       In the event of a subdivision of the
                                  outstanding common stock of Fair, Isaac, a
                                  declaration of a dividend payable in common
                                  stock, a declaration of a dividend payable in
                                  a form other than common stock in an amount
                                  that has material effect on the price of
                                  common stock, a combination or consolidation
                                  of the outstanding common stock (by
                                  reclassification or otherwise) into a lesser
                                  number of common stock, a recapitalization, a
                                  spinoff or a similar occurrence, the
                                  Compensation Committee of the Board of
                                  Directors shall make appropriate adjustments
                                  in (a) the number of shares of common stock
                                  underlying this option and (b) the exercise
                                  price under this option. Except as provide
                                  herein you shall have no rights by reason of
                                  any issue by the Company of stock of any class
                                  or securities convertible into stock of any
                                  class, any subdivision or consolidation of
                                  shares of stock of any class, the payment of
                                  any stock dividend or any other increase or
                                  decrease in the number of shares of stock of
                                  any class.

                                  In the event that the Company is a party to a
                                  merger or other reorganization, this option
                                  shall be subject to the agreement of merger or
                                  reorganization. Such agreement may provide,
                                  without limitation, for the assumption of this
                                  option by the surviving corporation or its
                                  parent, for their continuation by the Company
                                  (if the Company is a surviving corporation),
                                  or for settlement in cash.

APPLICABLE LAW                    This Agreement will be interpreted and
                                  enforced under the laws of the State of
                                  Delaware (without regard to its rules on
                                  choice of law).

OTHER AGREEMENTS                  This Agreement constitutes the entire
                                  understanding between you and Fair, Isaac
                                  regarding this option. Any prior agreements,
                                  commitments or negotiations concerning this
                                  option are superseded. This Agreement may be
                                  amended only in writing.

                                  BY SIGNING THE NOTICE OF GRANT AND STOCK
                                  OPTION AGREEMENT, YOU AGREE TO ALL OF THE
