Item 5.  Other Events.
         ------------

                                SUMMARY OF RIGHTS

         On August 7, 2001,  the Board of Directors of Fair,  Isaac and Company,
Incorporated (the "Company") declared a dividend distribution of one "Right" for
each  outstanding  share of common stock (the "Common  Stock") of the Company to
stockholders  of record at the close of business on August 21, 2001 (the "Record
Date").  Except as set forth below, each Right,  when exercisable,  entitles the
registered holder to purchase from the Company one  one-thousandth of a share of
a new series of preferred stock,  designated as Series A Participating Preferred
Stock (the "Preferred Stock"), at a price of Two Hundred Forty Dollars ($240.00)
per one one-thousandth of a share (the "Purchase Price"), subject to adjustment.
The description and terms of the Rights are set forth in a Rights Agreement (the
"Rights  Agreement")  between the Company and Mellon  Investor  Services LLC, as
"Rights Agent."

         Initially, the Rights will be attached to all Common Stock certificates
representing  shares then outstanding,  and no separate Rights certificates will
be  distributed.   The  Rights  will  separate  from  the  Common  Stock  and  a
"Distribution Date" will occur upon the earliest of the following:  (i) a public
announcement that a person,  entity or group of affiliated or associated persons
or entities  (an  "Acquiring  Person")  has  acquired,  or obtained the right to
acquire,   beneficial  ownership  of  fifteen  percent  (15%)  or  more  of  the
outstanding shares of Common Stock (other than (A) as a result of repurchases of
stock by the Company or certain  inadvertent actions by institutional or certain
other  stockholders,  (B) the  Company,  any  subsidiary  of the  Company or any
employee  benefit plan of the Company or any  subsidiary  and (C) certain  other
instances  set forth in the Rights  Agreement);  or (ii) ten (10)  business days
(unless  such  date  is  extended  by the  Board  of  Directors)  following  the
commencement  of a tender  offer or exchange  offer  which  would  result in any
person, entity or group of affiliated or associated persons or entities becoming
an Acquiring  Person  (unless such tender offer or exchange offer is a Permitted
Offer (defined below)).

         Until the Distribution Date (or earlier redemption or expiration of the
Rights,  if applicable),  (i) the Rights will be evidenced by  certificates  for
Common Stock and will be transferred  only with such Common Stock  certificates,
(ii) new Common Stock  certificates  issued after the Record Date upon transfers
or new issuances of the Common Stock will contain a notation  incorporating  the
Rights  Agreement  by  reference  and (iii) the  surrender  for  transfer of any
certificates  for outstanding  Common Stock will also constitute the transfer of
the Rights  associated with such Common Stock. As soon as practicable  following
the  Distribution  Date,  separate  certificates  evidencing the Rights ("Rights
Certificates") will be mailed to holders of record of the Common Stock as of the
close of business on the Distribution Date, and the separate Rights Certificates
alone will evidence the Rights.

         The Rights are not  exercisable  unless and until a  Distribution  Date
occurs.  The Rights  will  expire on the  earliest  of (i) August 9, 2011,  (ii)
consummation  of a merger  transaction  with a  person,  entity or group who (x)
acquired  Common Stock pursuant to a Permitted  Offer and (y) is offering in the
merger the same price per share and form of consideration  paid in the Permitted
Offer or (iii)  redemption or exchange of the Rights by the Company as described
below.

                                       2




         The number of Rights  associated  with each share of Common Stock shall
be  proportionately  adjusted  in  the  event  of  a  stock  dividend  on,  or a
subdivision,  combination or reclassification of, the Common Stock. The Purchase
Price  payable,  and the number of one  one-thousandths  of a share of Preferred
Stock or other securities or property issuable,  upon exercise of the Rights are
subject to adjustment from time to time (i) in the event of a stock dividend on,
or a subdivision,  combination or  reclassification of the Preferred Stock, (ii)
upon the grant to holders of the Preferred Stock of certain  rights,  options or
warrants to subscribe for Preferred  Stock,  certain  convertible  securities or
securities having the same or more favorable rights,  privileges and preferences
as the  Preferred  Stock at less than the current  market price of the Preferred
Stock or (iii)  upon the  distribution  to  holders  of the  Preferred  Stock of
evidences of indebtedness or assets (excluding  regular quarterly cash dividends
out of earnings or retained  earnings)  or of  subscription  rights,  options or
warrants  (other than those  referred to above).  With  certain  exceptions,  no
adjustments in the Purchase Price will be required until cumulative  adjustments
require an adjustment of at least one percent (1%) in such Purchase Price.

         In the event that,  after the first date of public  announcement by the
Company or an  Acquiring  Person that an Acquiring  Person has become such,  the
Company  is  involved  in a merger  or other  business  combination  transaction
(whether or not the Company is the surviving corporation) or fifty percent (50%)
or more of the Company's assets or earning power are sold (in one transaction or
a series of transactions), proper provision shall be made so that each holder of
a Right  (other than an Acquiring  Person)  shall  thereafter  have the right to
receive,  upon the exercise  thereof at the then current  Purchase  Price,  that
number of shares of common stock of either the Company,  in the event that it is
the surviving corporation of a merger or consolidation, or the acquiring company
(or,  in the  event  there is more than one  acquiring  company,  the  acquiring
company   receiving  the  greatest  portion  of  the  assets  or  earning  power
transferred)  which at the time of such transaction would have a market value of
two (2) times the Purchase  Price (such right being called the "Merger  Right").
In the event that a person,  entity or group becomes an Acquiring Person (unless
pursuant  to a tender  offer or  exchange  offer for all  outstanding  shares of
Common Stock at a price and on terms  determined  prior to the date of the first
acceptance  of  payment  for any of such  shares by at least a  majority  of the
members of the Board of  Directors  who are not  officers of the Company and are
not Acquiring Persons (or affiliated or associated  persons or entities thereof)
to be fair to, and in the best interests of, the Company and its stockholders (a
"Permitted Offer")),  then proper provision shall be made so that each holder of
a Right will,  for a sixty (60) day period  (subject to extension  under certain
circumstances)  thereafter,  have the right to receive upon exercise that number
of shares of Common Stock (or, at the election of the  Company,  which  election
may be  obligatory  if  sufficient  authorized  shares of  Common  Stock are not
available,  a combination of Common Stock,  property,  other  securities  (e.g.,
Preferred  Stock)  or cash  (including  by way of a  reduction  in the  Purchase
Price))  having a market value of two (2) times the  Purchase  Price (such right
being called the "Subscription  Right").  The holder of a Right will continue to
have the Merger  Right  whether or not such holder  exercises  the  Subscription
Right.  Notwithstanding the foregoing,  upon the occurrence of any of the events
giving rise to the exercisability of the Merger Right or the Subscription Right,
any Rights that are or were at any time after the Distribution  Date owned by an
Acquiring Person (or affiliated or associated persons or entities thereof) shall
immediately become null and void.

                                       3



         At any time prior to the  earlier  to occur of (i) a person,  entity or
group  becoming an Acquiring  Person or (ii) the  expiration of the Rights,  the
Company  may redeem the Rights in whole,  but not in part,  at a price of $0.001
per Right (the "Redemption Price"), which redemption shall be effective upon the
action of the Board of  Directors.  Additionally,  the Company may,  following a
person,   entity  or  group  becoming  an  Acquiring  Person,  redeem  the  then
outstanding  Rights in whole,  but not in part, at the  Redemption  Price (i) if
such  redemption  is  incidental  to a  merger  or  other  business  combination
transaction or series of transactions involving the Company but not involving an
Acquiring  Person (or certain  related persons or entities) or (ii) following an
event  giving  rise to, and the  expiration  of the  exercise  period  for,  the
Subscription  Right if and for as long as the Acquiring  Person  triggering  the
Subscription Right  beneficially owns securities  representing less than fifteen
percent  (15%) of the  outstanding  shares  of  Common  Stock and at the time of
redemption  there  are no other  Acquiring  Persons.  The  redemption  of Rights
described in the preceding sentence shall be effective only as of such time when
the  Subscription  Right  is not  exercisable.  Upon the  effective  date of the
redemption  of the Rights,  the right to exercise the Rights will  terminate and
the only right of the holders of Rights will be to receive the Redemption Price.

         Subject to applicable law, the Board of Directors,  at its option,  may
at any time after a person, group or entity becomes an Acquiring Person (but not
after the acquisition by such Acquiring Person of fifty percent (50%) or more of
the  outstanding  shares  of  Common  Stock),  exchange  all or part of the then
outstanding  and  exercisable  Rights (except for Rights which have become void)
for  shares  of Common  Stock at a rate of one  share of Common  Stock per Right
(subject  to  adjustment)  or,  alternatively,   for  substitute   consideration
consisting  of  cash,  securities  of  the  Company  or  other  assets  (or  any
combination thereof).

         The  Preferred  Stock  purchasable  upon exercise of the Rights will be
nonredeemable  and junior to any other series of preferred stock the Company may
issue  (unless  otherwise  provided in the terms of such  stock).  Each share of
Preferred Stock will have a preferential  quarterly  dividend in an amount equal
to 1,000 times the dividend  declared on each share of Common  Stock,  but in no
event less than $25.00.  In the event of  liquidation,  the holders of shares of
Preferred Stock will receive a preferred  liquidation  payment equal, per share,
to the greater of  $1,000.00 or 1,000 times the payment made per share of Common
Stock. Each share of Preferred Stock will have 1,000 votes, voting together with
the shares of Common Stock. In the event of any merger,  consolidation  or other
transaction  in which  shares  of  Common  Stock are  exchanged,  each  share of
Preferred  Stock will be entitled to receive  1,000 times the amount and type of
consideration  received per share of Common  Stock.  The rights of the Preferred
Stock as to dividends,  liquidation and voting,  and in the event of mergers and
consolidations,  are protected by customary antidilution provisions.  Fractional
shares of Preferred  Stock will be issuable;  however,  the Company may elect to
(i) distribute  depositary  receipts in lieu of such fractional  shares and (ii)
make an adjustment in cash,  in lieu of fractional  shares other than  fractions
that are multiples of one  one-thousandth of a share,  based on the market price
of the Preferred Stock prior to the date of exercise.

         Until a Right is exercised,  the holder thereof,  as such, will have no
rights as a stockholder of the Company, including, without limitation, the right
to vote or to receive dividends. While the distribution of the Rights should not
be taxable to stockholders or to the Company,  holders of Rights may,  depending
upon the  circumstances,  recognize  taxable  income  in the  event (i) that the


                                       4




Rights  become  exercisable  for (x) Common Stock or  Preferred  Stock (or other
consideration)  or (y) common stock of an  acquiring  company in the instance of
the Merger Right as set forth above or (ii) of any redemption or exchange of the
Rights as set forth above.

         The Company and the Rights Agent  retain  broad  authority to amend the
Rights Agreement; however, following any Distribution Date any amendment may not
adversely affect the interests of holders of Rights.

         A copy of the Rights  Agreement has been filed with the  Securities and
Exchange  Commission  as an Exhibit to a  Registration  Statement on Form 8-A. A
copy of the Rights Agreement is available free of charge from the Company.  THIS
SUMMARY  DESCRIPTION  OF THE  RIGHTS  DOES NOT  PURPORT  TO BE  COMPLETE  AND IS
QUALIFIED  IN ITS  ENTIRETY  BY  REFERENCE  TO THE  RIGHTS  AGREEMENT,  WHICH IS
INCORPORATED HEREIN BY REFERENCE.

                   Fair, Isaac Adopts Stockholder Rights Plan

SAN RAFAEL, Calif.--August 9, 2001--Fair, Isaac and Company, Incorporated (NYSE:
FIC) today  announced  that its Board of  Directors  has  adopted a  Stockholder
Rights Plan. Under the Rights Plan,  rights will be distributed as a dividend at
the rate of one  right  for each  share of Fair,  Isaac  common  stock,  held by
stockholders of record as of the close of business on August 21, 2001.

The Rights Plan is designed to enable all Fair,  Isaac  stockholders  to realize
the full value of their  investment and to provide for fair and equal  treatment
for all stockholders in the event that an unsolicited attempt is made to acquire
Fair,  Isaac.  The  adoption  of the Rights Plan is intended as a means to guard
against abusive takeover  tactics.  While the Company as a matter of policy does
not comment on the existence or absence of takeover  proposals,  the Stockholder
Rights Plan was adopted only for precautionary purposes to protect the rights of
the stockholders and not in response to any known takeover proposal.

The rights will be  distributed  as a  non-taxable  dividend and will expire ten
years  from  the  date of  adoption  of the  Rights  Plan.  The  rights  will be
exercisable  only if a person  or group  acquires  15  percent  or more of Fair,
Isaac's  common  stock,  subject to certain  exceptions  set forth in the Rights
Plan.  If a person  acquires 15 percent or more of Fair,  Isaac's  common  stock
while the Rights Plan remains in place,  all rights  holders,  except the buyer,
will be entitled to acquire Fair,  Isaac common stock at a discount.  The effect
will be to discourage acquisitions of 15 percent or more of Fair, Isaac's common
stock in the absence of negotiations with the Company's Board of Directors.

The rights will trade with Fair,  Isaac's common stock unless and until they are
separated upon the occurrence of certain future events.  Fair,  Isaac's Board of
Directors  may  terminate the Rights Plan at any time or redeem the rights prior
to the time a person acquires 15 percent or more of Fair,  Isaac's common stock.
Additional details regarding

                                     -more-


the Rights Plan will be  outlined in a summary to be mailed to all  stockholders
following  the record date,  and a copy of the Rights Plan will be filed shortly
with the Securities and Exchange Commission.
