                                HNC SOFTWARE INC.

                           1995 EQUITY INCENTIVE PLAN

                             As Adopted May 4, 1995
 As Amended January 11, 1996 (effective as of July 27, 1995), December 6, 1996,
      November 25, 1997, May 21, 1998, November 20, 1998 and May 20, 1999

             1. PURPOSE. The purpose of this Plan is to provide incentives to
attract, retain and motivate eligible persons whose present and potential
contributions are important to the success of the Company, its Parent,
Subsidiaries and Affiliates, by offering them an opportunity to participate in
the Company's future performance through awards of Options, Restricted Stock and
Stock Bonuses. Capitalized terms not defined in the text are defined in Section
23.

             2. SHARES SUBJECT TO THE PLAN.

                     2.1 Number of Shares Available. Subject to Sections 2.2 and
18, the total number of Shares reserved and available for grant and issuance
pursuant to this Plan will be 7,250,000(1) Shares plus any Shares that are made
available for grant and issuance under this Plan pursuant to the following
sentence. Any Shares remaining unissued under the 1987 Stock Option Plan adopted
by HNC Software Inc., a California corporation that is the Company's predecessor
(the "PRIOR PLAN") on the Effective Date (as defined below) and any Shares
issuable upon exercise of options granted pursuant to the Prior Plan that expire
or become unexercisable for any reason without having been exercised in full,
will no longer be available for grant and issuance under the Prior Plan, but
will also be available for grant and issuance under this Plan. Subject to
Sections 2.2 and 18, Shares that: (a) are subject to issuance upon exercise of
an Option but cease to be subject to such Option for any reason other than
exercise of such Option; (b) are subject to an Award granted hereunder but are
forfeited or are repurchased by the Company at the original issue price; or (c)
are subject to an Award that otherwise terminates without Shares being issued;
will again be available for grant and issuance in connection with future Awards
under this Plan. At all times the Company shall reserve and keep available a
sufficient number of Shares as shall be required to satisfy the requirements of
all outstanding Options granted under this Plan and all other outstanding but
unvested Awards granted under this Plan.

                     2.2 Adjustment of Shares. In the event that the number of
outstanding Shares is changed by a stock dividend, recapitalization, stock
split, reverse stock split, subdivision, combination, reclassification or
similar change in the capital structure of the Company without consideration,
then (a) the number of Shares reserved for issuance under this Plan, (b) the
Exercise Prices of and number of Shares subject to outstanding Options, and (c)
the number of Shares subject to other outstanding Awards will be proportionately
adjusted, subject to any required action by the Board or the stockholders of the
Company and compliance with applicable securities laws; provided, however, that
fractions of a Share will not be issued but will

(1) Adjusted to reflect (i) the 2-for-1 split of the Company's capital stock
    effected in April 1996; (ii) the authorization of 1,500,000 additional
    shares of Common Stock for issuance under the Plan approved by the Company's
    stockholders on December 6, 1996; (iii) the authorization of 750,000
    additional shares of Common Stock for issuance under the Plan approved by
    the Company's stockholders on November 25, 1997; (iv) the authorization of
    1,000,000 additional shares of Common Stock for issuance under the Plan
    approved by the Company's stockholders on May 21, 1998; (v) the
    authorization of 700,000 additional shares of Common Stock for issuance
    under the Plan approved by the Company's stockholders on November 20, 1998;
    and (vi) the authorization of 2,000,000 additional shares of Common Stock
    for issuance under the Plan approved by the Company's stockholders on May
    20, 1999.

either be replaced by a cash payment equal to the Fair Market Value of such
fraction of a Share or will be rounded up to the nearest whole Share, as
determined by the Committee.

             3. ELIGIBILITY. ISOs (as defined in Section 5 below) may be granted
only to employees (including officers and directors who are also employees) of
the Company or of a Parent or Subsidiary of the Company. All other Awards may be
granted to employees, officers, directors, consultants, independent contractors
and advisors of the Company or any Parent, Subsidiary or Affiliate of the
Company; provided such consultants, contractors and advisors render bona fide
services not in connection with the offer and sale of securities in a
capital-raising transaction. No person will be eligible to receive more than
500,000(2) Shares in any calendar year under this Plan pursuant to the grant of
Awards hereunder, other than new employees of the Company or of a Parent,
Subsidiary or Affiliate of the Company (including new employees who are also
officers and directors of the Company or any Parent, Subsidiary or Affiliate of
the Company) who are eligible to receive up to a maximum of 700,000(3) Shares in
the calendar year in which they commence their employment. A person may be
granted more than one Award under this Plan.

             4. ADMINISTRATION.

                     4.1 Committee Authority. This Plan will be administered by
the Committee or by the Board acting as the Committee. Subject to the general
purposes, terms and conditions of this Plan, and to the direction of the Board,
the Committee will have full power to implement and carry out this Plan. Without
limitation, the Committee will have the authority to:

             (a)     construe and interpret this Plan, any Award Agreement and
                     any other agreement or document executed pursuant to this
                     Plan;

             (b)     prescribe, amend and rescind rules and regulations relating
                     to this Plan;

             (c)     select persons to receive Awards;

             (d)     determine the form and terms of Awards;

             (e)     determine the number of Shares or other consideration
                     subject to Awards;

             (f)     determine whether Awards will be granted singly, in
                     combination with, in tandem with, in replacement of, or as
                     alternatives to, other Awards under this Plan or any other
                     incentive or compensation plan of the Company or any
                     Parent, Subsidiary or Affiliate of the Company;

             (g)     grant waivers of Plan or Award conditions;

             (h)     determine the vesting, exercisability and payment of
                     Awards;

             (i)     correct any defect, supply any omission or reconcile any
                     inconsistency in this Plan, any Award or any Award
                     Agreement;



- --------

(2)  Adjusted to reflect the 2-for-1 split of the Company's capital stock
     effected in April 1996.

(3)  Adjusted to reflect the 2-for-1 split of the Company's capital stock
     effected in April 1996.




   3

             (j)     determine whether an Award has been earned; and

             (k)     make all other determinations necessary or advisable for
                     the administration of this Plan.

                     4.2 Committee Discretion. Any determination made by the
Committee with respect to any Award will be made in its sole discretion at the
time of grant of the Award or, unless in contravention of any express term of
this Plan or Award, at any later time, and such determination will be final and
binding on the Company and on all persons having an interest in any Award under
this Plan. The Committee may delegate to one or more officers of the Company the
authority to grant an Award under this Plan to Participants who are not Insiders
of the Company.

                     4.3 Exchange Act Requirements. If two or more members of
the Board are Outside Directors, the Committee will be comprised of at least two
(2) members of the Board, all of whom are Outside Directors and Disinterested
Persons. During all times that the Company is subject to Section 16 of the
Exchange Act, the Company will take appropriate steps to comply with the
disinterested administration requirements of Section 16(b) of the Exchange Act,
which will consist of the appointment by the Board of a Committee consisting of
not less than two (2) members of the Board, each of whom is a Disinterested
Person.

             5. OPTIONS. The Committee may grant Options to eligible persons and
will determine whether such Options will be Incentive Stock Options within the
meaning of the Code ("ISOS") or Nonqualified Stock Options ("NQSOS"), the number
of Shares subject to the Option, the Exercise Price of the Option, the period
during which the Option may be exercised, and all other terms and conditions of
the Option, subject to the following:

                     5.1 Form of Option Grant. Each Option granted under this
Plan will be evidenced by an Award Agreement which will expressly identify the
Option as an ISO or an NQSO ("STOCK OPTION AGREEMENT"), and will be in such form
and contain such provisions (which need not be the same for each Participant) as
the Committee may from time to time approve, and which will comply with and be
subject to the terms and conditions of this Plan.

                     5.2 Date of Grant. The date of grant of an Option will be
the date on which the Committee makes the determination to grant such Option,
unless otherwise specified by the Committee. The Stock Option Agreement and a
copy of this Plan will be delivered to the Participant within a reasonable time
after the granting of the Option.

                     5.3 Exercise Period. Options will be exercisable within the
times or upon the events determined by the Committee as set forth in the Stock
Option Agreement governing such Option; provided, however, that no Option will
be exercisable after the expiration of ten (10) years from the date the Option
is granted; and provided further that no ISO granted to a person who directly or
by attribution owns more than ten percent (10%) of the total combined voting
power of all classes of stock of the Company or of any Parent or Subsidiary of
the Company ("TEN PERCENT STOCKHOLDER") will be exercisable after the expiration
of five (5) years from the date the ISO is granted. The Committee also may
provide for the exercise of Options to become exercisable at one time or from
time to time, periodically or otherwise, in such number of Shares or percentage
of Shares as the Committee determines.




   4

                     5.4 Exercise Price. The Exercise Price of an Option will be
determined by the Committee when the Option is granted and may be not less than
100% of the Fair Market Value of the Shares on the date of grant; provided that:
the Exercise Price of any ISO granted to a Ten Percent Shareholder will not be
less than 110% of the Fair Market Value of the Shares on the date of grant.
Payment for the Shares purchased may be made in accordance with Section 8 of
this Plan.

                     5.5 Method of Exercise. Options may be exercised only by
delivery to the Company of a written stock option exercise agreement (the
"EXERCISE AGREEMENT") in a form approved by the Committee (which need not be the
same for each Participant), stating the number of Shares being purchased, the
restrictions imposed on the Shares purchased under such Exercise Agreement, if
any, and such representations and agreements regarding Participant's investment
intent and access to information and other matters, if any, as may be required
or desirable by the Company to comply with applicable securities laws, together
with payment in full of the Exercise Price for the number of Shares being
purchased.

                     5.6 Termination. Notwithstanding the exercise periods set
forth in the Stock Option Agreement, exercise of an Option will always be
subject to the following:

             (a)     If the Participant is Terminated for any reason except
                     death or Disability, then the Participant may exercise such
                     Participant's Options only to the extent that such Options
                     would have been exercisable upon the Termination Date no
                     later than three (3) months after the Termination Date (or
                     such shorter or longer time period not exceeding five (5)
                     years as may be determined by the Committee, with any
                     exercise beyond three (3) months after the Termination Date
                     deemed to be an NQSO), but in any event, no later than the
                     expiration date of the Options.

             (b)     If the Participant is Terminated because of Participant's
                     death or Disability (or the Participant dies within three
                     (3) months after a Termination other than because of
                     Participant's death or disability), then Participant's
                     Options may be exercised only to the extent that such
                     Options would have been exercisable by Participant on the
                     Termination Date and must be exercised by Participant (or
                     Participant's legal representative or authorized assignee)
                     no later than twelve (12) months after the Termination Date
                     (or such shorter or longer time period not exceeding five
                     (5) years as may be determined by the Committee, with any
                     such exercise beyond (a) three (3) months after the
                     Termination Date when the Termination is for any reason
                     other than the Participant's death or Disability, or (b)
                     twelve (12) months after the Termination Date when the
                     Termination is for Participant's death or Disability,
                     deemed to be an NQSO), but in any event no later than the
                     expiration date of the Options.

                     5.7 Limitations on Exercise. The Committee may specify a
reasonable minimum number of Shares that may be purchased on any exercise of an
Option, provided that such minimum number will not prevent Participant from
exercising the Option for the full number of Shares for which it is then
exercisable.

                     5.8 Limitations on ISOs. The aggregate Fair Market Value
(determined as of the date of grant) of Shares with respect to which ISOs are
exercisable for the first time by a




   5

Participant during any calendar year (under this Plan or under any other
incentive stock option plan of the Company or any Affiliate, Parent or
Subsidiary of the Company) will not exceed $100,000. If the Fair Market Value of
Shares on the date of grant with respect to which ISOs are exercisable for the
first time by a Participant during any calendar year exceeds $100,000, then the
Options for the first $100,000 worth of Shares to become exercisable in such
calendar year will be ISOs and the Options for the amount in excess of $100,000
that become exercisable in that calendar year will be NQSOs. In the event that
the Code or the regulations promulgated thereunder are amended after the
Effective Date of this Plan to provide for a different limit on the Fair Market
Value of Shares permitted to be subject to ISOs, such different limit will be
automatically incorporated herein and will apply to any Options granted after
the effective date of such amendment.

                     5.9 Modification, Extension or Renewal. The Committee may
modify, extend or renew outstanding Options and authorize the grant of new
Options in substitution therefor, provided that any such action may not, without
the written consent of a Participant, impair any of such Participant's rights
under any Option previously granted. Any outstanding ISO that is modified,
extended, renewed or otherwise altered will be treated in accordance with
Section 424(h) of the Code. The Committee may reduce the Exercise Price of
outstanding Options without the consent of Participants affected by a written
notice to them; provided, however, that the Exercise Price may not be reduced
below the minimum Exercise Price that would be permitted under Section 5.4 of
this Plan for Options granted on the date the action is taken to reduce the
Exercise Price.

                     5.10 No Disqualification. Notwithstanding any other
provision in this Plan, no term of this Plan relating to ISOs will be
interpreted, amended or altered, nor will any discretion or authority granted
under this Plan be exercised, so as to disqualify this Plan under Section 422 of
the Code or, without the consent of the Participant affected, to disqualify any
ISO under Section 422 of the Code.

             6. RESTRICTED STOCK. A Restricted Stock Award is an offer by the
Company to sell to an eligible person Shares that are subject to restrictions.
The Committee will determine to whom an offer will be made, the number of Shares
the person may purchase, the price to be paid (the "PURCHASE PRICE"), the
restrictions to which the Shares will be subject, and all other terms and
conditions of the Restricted Stock Award, subject to the following:

                     6.1 Form of Restricted Stock Award. All purchases under a
Restricted Stock Award made pursuant to this Plan will be evidenced by an Award
Agreement ("RESTRICTED STOCK PURCHASE AGREEMENT") that will be in such form
(which need not be the same for each Participant) as the Committee will from
time to time approve, and will comply with and be subject to the terms and
conditions of this Plan. The offer of Restricted Stock will be accepted by the
Participant's execution and delivery of the Restricted Stock Purchase Agreement
and full payment for the Shares to the Company within thirty (30) days from the
date the Restricted Stock Purchase Agreement is delivered to the person. If such
person does not execute and deliver the Restricted Stock Purchase Agreement
along with full payment for the Shares to the Company within thirty (30) days,
then the offer will terminate, unless otherwise determined by the Committee.

                     6.2 Purchase Price. The Purchase Price of Shares sold
pursuant to a Restricted Stock Award will be determined by the Committee and
will be at least 100% of the




   6

Fair Market Value of the Shares on the date the Restricted Stock Award is
granted. Payment of the Purchase Price may be made in accordance with Section 8
of this Plan.

                     6.3 Restrictions. Restricted Stock Awards will be subject
to such restrictions (if any) as the Committee may impose. The Committee may
provide for the lapse of such restrictions in installments and may accelerate or
waive such restrictions, in whole or part, based on length of service,
performance or such other factors or criteria as the Committee may determine.

             7. STOCK BONUSES.

                     7.1 Awards of Stock Bonuses. A Stock Bonus is an award of
Shares (which may consist of Restricted Stock) for services rendered to the
Company or any Parent, Subsidiary or Affiliate of the Company. A Stock Bonus may
be awarded for past services already rendered to the Company, or any Parent,
Subsidiary or Affiliate of the Company (provided that the Participant pays the
Company the par value of the Shares awarded by such Stock Bonus in cash)
pursuant to an Award Agreement (the "STOCK BONUS AGREEMENT") that will be in
such form (which need not be the same for each Participant) as the Committee
will from time to time approve, and will comply with and be subject to the terms
and conditions of this Plan. A Stock Bonus may be awarded upon satisfaction of
such performance goals as are set out in advance in the Participant's individual
Award Agreement (the "PERFORMANCE STOCK BONUS AGREEMENT") that will be in such
form (which need not be the same for each Participant) as the Committee will
from time to time approve, and will comply with and be subject to the terms and
conditions of this Plan. Stock Bonuses may vary from Participant to Participant
and between groups of Participants, and may be based upon the achievement of the
Company, Parent, Subsidiary or Affiliate and/or individual performance factors
or upon such other criteria as the Committee may determine.

                     7.2 Terms of Stock Bonuses. The Committee will determine
the number of Shares to be awarded to the Participant and whether such Shares
will be Restricted Stock. If the Stock Bonus is being earned upon the
satisfaction of performance goals pursuant to a Performance Stock Bonus
Agreement, then the Committee will determine: (a) the nature, length and
starting date of any period during which performance is to be measured (the
"PERFORMANCE PERIOD") for each Stock Bonus; (b) the performance goals and
criteria to be used to measure the performance, if any; (c) the number of Shares
that may be awarded to the Participant; and (d) the extent to which such Stock
Bonuses have been earned. Performance Periods may overlap and Participants may
participate simultaneously with respect to Stock Bonuses that are subject to
different Performance Periods and different performance goals and other
criteria. The number of Shares may be fixed or may vary in accordance with such
performance goals and criteria as may be determined by the Committee. The
Committee may adjust the performance goals applicable to the Stock Bonuses to
take into account changes in law and accounting or tax rules and to make such
adjustments as the Committee deems necessary or appropriate to reflect the
impact of extraordinary or unusual items, events or circumstances to avoid
windfalls or hardships.

                     7.3 Form of Payment. The earned portion of a Stock Bonus
may be paid currently or on a deferred basis with such interest or dividend
equivalent, if any, as the Committee may determine. Payment may be made in the
form of cash, whole Shares, including Restricted Stock, or a combination
thereof, either in a lump sum payment or in installments, all as the Committee
will determine.




   7

                     7.4 Termination During Performance Period. If a Participant
is Terminated during a Performance Period for any reason, then such Participant
will be entitled to payment (whether in Shares, cash or otherwise) with respect
to the Stock Bonus only to the extent earned as of the date of Termination in
accordance with the Performance Stock Bonus Agreement, unless the Committee will
determine otherwise.

             8. PAYMENT FOR SHARE PURCHASES.

                     8.1 Payment. Payment for Shares purchased pursuant to this
Plan may be made in cash (by check) or, where expressly approved for the
Participant by the Committee and where permitted by law:

             (a)     by cancellation of indebtedness of the Company to the
                     Participant;

             (b)     by surrender of shares that either: (1) have been owned by
                     Participant for more than six (6) months and have been paid
                     for within the meaning of SEC Rule 144 (and, if such shares
                     were purchased from the Company by use of a promissory
                     note, such note has been fully paid with respect to such
                     shares); or (2) were obtained by Participant in the public
                     market;

             (c)     by tender of a full recourse promissory note having such
                     terms as may be approved by the Committee and bearing
                     interest at a rate sufficient to avoid imputation of income
                     under Sections 483 and 1274 of the Code; provided, however,
                     that Participants who are not employees or directors of the
                     Company will not be entitled to purchase Shares with a
                     promissory note unless the note is adequately secured by
                     collateral other than the Shares; provided, further, that
                     the portion of the Purchase Price equal to the par value of
                     the Shares, if any, must be paid in cash;

             (d)     by waiver of compensation due or accrued to the Participant
                     for services rendered; provided, further, that the portion
                     of the Purchase Price equal to the par value of the Shares,
                     if any, must be paid in cash;

             (e)     with respect only to purchases upon exercise of an Option,
                     and provided that a public market for the Company's stock
                     exists:

                     (1)    through a "same day sale" commitment from the
                            Participant and a broker-dealer that is a member of
                            the National Association of Securities Dealers (an
                            "NASD DEALER") whereby the Participant irrevocably
                            elects to exercise the Option and to sell a portion
                            of the Shares so purchased to pay for the Exercise
                            Price, and whereby the NASD Dealer irrevocably
                            commits upon receipt of such Shares to forward the
                            Exercise Price directly to the Company; or

                     (2)    through a "margin" commitment from the Participant
                            and a NASD Dealer whereby the Participant
                            irrevocably elects to exercise the Option and to
                            pledge the Shares so purchased to the NASD Dealer in
                            a margin account as security for a loan from the
                            NASD Dealer in the amount of the Exercise Price, and
                            whereby the NASD Dealer




   8

                            irrevocably commits upon receipt of such Shares to
                            forward the Exercise Price directly to the Company;
                            or

             (f)     by any combination of the foregoing.

                     8.2 Loan Guarantees. The Committee may help the Participant
pay for Shares purchased under this Plan by authorizing a guarantee by the
Company of a third-party loan to the Participant.

             9. WITHHOLDING TAXES.

                     9.1 Withholding Generally. Whenever Shares are to be issued
in satisfaction of Awards granted under this Plan, the Company may require the
Participant to remit to the Company an amount sufficient to satisfy federal,
state and local withholding tax requirements prior to the delivery of any
certificate or certificates for such Shares. Whenever, under this Plan, payments
in satisfaction of Awards are to be made in cash, such payment will be net of an
amount sufficient to satisfy federal, state, and local withholding tax
requirements.

                     9.2 Stock Withholding. When, under applicable tax laws, a
Participant incurs tax liability in connection with the exercise or vesting of
any Award that is subject to tax withholding and the Participant is obligated to
pay the Company the amount required to be withheld, the Committee may allow the
Participant to satisfy the minimum withholding tax obligation by electing to
have the Company withhold from the Shares to be issued that number of Shares
having a Fair Market Value equal to the minimum amount required to be withheld,
determined on the date that the amount of tax to be withheld is to be determined
(the "TAX DATE"). All elections by a Participant to have Shares withheld for
this purpose will be made in writing in a form acceptable to the Committee and
will be subject to the following restrictions:

             (a)     the election must be made on or prior to the applicable Tax
                     Date;

             (b)     once made, then except as provided below, the election will
                     be irrevocable as to the particular Shares as to which the
                     election is made;

             (c)     all elections will be subject to the consent or disapproval
                     of the Committee;

             (d)     if the Participant is an Insider and if the Company is
                     subject to Section 16(b) of the Exchange Act: (1) the
                     election may not be made within six (6) months of the date
                     of grant of the Award, except as otherwise permitted by SEC
                     Rule 16b-3(e) under the Exchange Act, and (2) either (A)
                     the election to use stock withholding must be irrevocably
                     made at least six (6) months prior to the Tax Date
                     (although such election may be revoked at any time at least
                     six (6) months prior to the Tax Date) or (B) the exercise
                     of the Option or election to use stock withholding must be
                     made in the ten (10) day period beginning on the third day
                     following the release of the Company's quarterly or annual
                     summary statement of sales or earnings; and

             (e)     in the event that the Tax Date is deferred until six (6)
                     months after the delivery of Shares under Section 83(b) of
                     the Code, the Participant will receive the full number of
                     Shares with respect to which the exercise occurs,




   9

                     but such Participant will be unconditionally obligated to
                     tender back to the Company the proper number of Shares on
                     the Tax Date.

             10. PRIVILEGES OF STOCK OWNERSHIP.

                     10.1 Voting and Dividends. No Participant will have any of
the rights of a stockholder with respect to any Shares until the Shares are
issued to the Participant. After Shares are issued to the Participant, the
Participant will be a stockholder and have all the rights of a stockholder with
respect to such Shares, including the right to vote and receive all dividends or
other distributions made or paid with respect to such Shares; provided, that if
such Shares are Restricted Stock, then any new, additional or different
securities the Participant may become entitled to receive with respect to such
Shares by virtue of a stock dividend, stock split or any other change in the
corporate or capital structure of the Company will be subject to the same
restrictions as the Restricted Stock; provided, further, that the Participant
will have no right to retain such stock dividends or stock distributions with
respect to Shares that are repurchased at the Participant's original Purchase
Price pursuant to Section 12.

                     10.2 Financial Statements. The Company will provide
financial statements to each Participant prior to such Participant's purchase of
Shares under this Plan, and to each Participant annually during the period such
Participant has Awards outstanding; provided, however, the Company will not be
required to provide such financial statements to Participants whose services in
connection with the Company assure them access to equivalent information.

             11. TRANSFERABILITY. Awards granted under this Plan, and any
interest therein, will not be transferable or assignable by Participant, and may
not be made subject to execution, attachment or similar process, otherwise than
by will or by the laws of descent and distribution or as consistent with the
specific Plan and Award Agreement provisions relating thereto. During the
lifetime of the Participant an Award will be exercisable only by the
Participant, and any elections with respect to an Award, may be made only by the
Participant.

             12. RESTRICTIONS ON SHARES. At the discretion of the Committee, the
Company may reserve to itself and/or its assignee(s) in the Award Agreement (a)
a right of first refusal to purchase all Shares that a Participant (or a
subsequent transferee) may propose to transfer to a third party, and/or (b) a
right to repurchase a portion of or all Shares held by a Participant following
such Participant's Termination at any time within ninety (90) days after the
later of Participant's Termination Date and the date Participant purchases
Shares under this Plan, for cash and/or cancellation of purchase money
indebtedness, at: (A) with respect to Shares that are "Vested" (as defined in
the Award Agreement), the higher of: (l) Participant's original Purchase Price,
or (2) the Fair Market Value of such Shares on Participant's Termination Date,
provided, that such right of repurchase (i) must be exercised as to all such
"Vested" Shares unless a Participant consents to the Company's repurchase of
only a portion of such "Vested" Shares and (ii) terminates when the Company's
securities become publicly traded; or (B) with respect to Shares that are not
"Vested" (as defined in the Award Agreement), at the Participant's original
Purchase Price, provided, that the right to repurchase at the original Purchase
Price lapses at the rate of at least 20% per year over five (5) years from the
date the Shares were purchased (or from the date of grant of options in the case
of Shares obtained pursuant to a Stock Option Agreement and Stock Option
Exercise Agreement), and if the right to repurchase is assignable, the assignee
must pay the Company, upon assignment of the right to repurchase, cash equal to
the excess of the Fair Market Value of the Shares over the original Purchase
Price.




   10

             13. CERTIFICATES. All certificates for Shares or other securities
delivered under this Plan will be subject to such stock transfer orders, legends
and other restrictions as the Committee may deem necessary or advisable,
including restrictions under any applicable federal, state or foreign securities
law, or any rules, regulations and other requirements of the SEC or any stock
exchange or automated quotation system upon which the Shares may be listed or
quoted.

             14. ESCROW; PLEDGE OF SHARES. To enforce any restrictions on a
Participant's Shares, the Committee may require the Participant to deposit all
certificates representing Shares, together with stock powers or other
instruments of transfer approved by the Committee, appropriately endorsed in
blank, with the Company or an agent designated by the Company to hold in escrow
until such restrictions have lapsed or terminated, and the Committee may cause a
legend or legends referencing such restrictions to be placed on the
certificates. Any Participant who is permitted to execute a promissory note as
partial or full consideration for the purchase of Shares under this Plan will be
required to pledge and deposit with the Company all or part of the Shares so
purchased as collateral to secure the payment of Participant's obligation to the
Company under the promissory note; provided, however, that the Committee may
require or accept other or additional forms of collateral to secure the payment
of such obligation and, in any event, the Company will have full recourse
against the Participant under the promissory note notwithstanding any pledge of
the Participant's Shares or other collateral. In connection with any pledge of
the Shares, Participant will be required to execute and deliver a written pledge
agreement in such form as the Committee will from time to time approve. The
Shares purchased with the promissory note may be released from the pledge on a
pro rata basis as the promissory note is paid.

             15. EXCHANGE AND BUYOUT OF AWARDS. The Committee may, at any time
or from time to time, authorize the Company, with the consent of the respective
Participants, to issue new Awards in exchange for the surrender and cancellation
of any or all outstanding Awards. The Committee may at any time buy from a
Participant an Award previously granted with payment in cash, Shares (including
Restricted Stock) or other consideration, based on such terms and conditions as
the Committee and the Participant may agree.

             16. SECURITIES LAW AND OTHER REGULATORY COMPLIANCE. An Award will
not be effective unless such Award is in compliance with all applicable federal
and state securities laws, rules and regulations of any governmental body, and
the requirements of any stock exchange or automated quotation system upon which
the Shares may then be listed or quoted, as they are in effect on the date of
grant of the Award and also on the date of exercise or other issuance.
Notwithstanding any other provision in this Plan, the Company will have no
obligation to issue or deliver certificates for Shares under this Plan prior to:
(a) obtaining any approvals from governmental agencies that the Company
determines are necessary or advisable; and/or (b) completion of any registration
or other qualification of such Shares under any state or federal law or ruling
of any governmental body that the Company determines to be necessary or
advisable. The Company will be under no obligation to register the Shares with
the SEC or to effect compliance with the registration, qualification or listing
requirements of any state securities laws, stock exchange or automated quotation
system, and the Company will have no liability for any inability or failure to
do so.

             17. NO OBLIGATION TO EMPLOY. Nothing in this Plan or any Award
granted under this Plan will confer or be deemed to confer on any Participant
any right to




   11
continue in the employ of, or to continue any other relationship with, the
Company or any Parent, Subsidiary or Affiliate of the Company or limit in any
way the right of the Company or any Parent, Subsidiary or Affiliate of the
Company to terminate Participant's employment or other relationship at any time,
with or without cause.

             18. CORPORATE TRANSACTIONS.

                     18.1 Assumption or Replacement of Awards by Successor. In
the event of (a) a dissolution or liquidation of the Company, (b) a merger or
consolidation in which the Company is not the surviving corporation (other than
a merger or consolidation with a wholly-owned subsidiary, a reincorporation of
the Company in a different jurisdiction, or other transaction in which there is
no substantial change in the stockholders of the Company or their relative stock
holdings and the Awards granted under this Plan are assumed, converted or
replaced by the successor corporation, which assumption will be binding on all
Participants), (c) a merger in which the Company is the surviving corporation
but after which the stockholders of the Company (other than any stockholder
which merges (or which owns or controls another corporation which merges) with
the Company in such merger) cease to own their shares or other equity interests
in the Company, (d) the sale of substantially all of the assets of the Company,
or (e) any other transaction which qualifies as a "corporate transaction" under
Section 424(a) of the Code wherein the stockholders of the Company give up all
of their equity interest in the Company (except for the acquisition, sale or
transfer of all or substantially all of the outstanding shares of the Company
from or by the stockholders of the Company), any or all outstanding Awards may
be assumed, converted or replaced by the successor corporation (if any), which
assumption, conversion or replacement will be binding on all Participants. In
the alternative, the successor corporation may substitute equivalent Awards or
provide substantially similar consideration to Participants as was provided to
stockholders (after taking into account the existing provisions of the Awards).
The successor corporation may also issue, in place of outstanding Shares of the
Company held by the Participant, substantially similar shares or other property
subject to repurchase restrictions no less favorable to the Participant. In the
event such successor corporation (if any) refuses to assume or substitute
Options, as provided above, pursuant to a transaction described in this
Subsection 18.1, such Options will expire on such transaction at such time and
on such conditions as the Board will determine.

                     18.2 Other Treatment of Awards. Subject to any greater
rights granted to Participants under the foregoing provisions of this Section
18, in the event of the occurrence of any transaction described in Section 18.1,
any outstanding Awards will be treated as provided in the applicable agreement
or plan of merger, consolidation, dissolution, liquidation, sale of assets or
other "corporate transaction."

                     18.3 Assumption of Awards by the Company. The Company, from
time to time, also may substitute or assume outstanding awards granted by
another company, whether in connection with an acquisition of such other company
or otherwise, by either; (a) granting an Award under this Plan in substitution
of such other company's award; or (b) assuming such award as if it had been
granted under this Plan if the terms of such assumed award could be applied to
an Award granted under this Plan. Such substitution or assumption will be
permissible if the holder of the substituted or assumed award would have been
eligible to be granted an Award under this Plan if the other company had applied
the rules of this Plan to such grant. In the event the Company assumes an award
granted by another company, the terms and conditions of such award will remain
unchanged (except that the exercise price and the number and nature of Shares
issuable upon exercise of any such option will be adjusted appropriately




   12

pursuant to Section 424(a) of the Code). In the event the Company elects to
grant a new Option rather than assuming an existing option, such new Option may
be granted with a similarly adjusted Exercise Price.

             19. ADOPTION AND STOCKHOLDER APPROVAL. This Plan will become
effective on the date on which the registration statement filed by the Company
with the SEC under the Securities Act registering the initial public offering of
the Company's Common Stock is declared effective by the SEC (the "EFFECTIVE
DATE"); provided, however, that if the Effective Date does not occur on or
before December 31, 1995, this Plan will terminate as of December 31, 1995
having never become effective. This Plan shall be approved by the stockholders
of the Company (excluding Shares issued pursuant to this Plan), consistent with
applicable laws, within twelve (12) months before or after the date this Plan is
adopted by the Board. Upon the Effective Date, the Board may grant Awards
pursuant to this Plan; provided, however, that: (a) no Option may be exercised
prior to initial stockholder approval of this Plan; (b) no Option granted
pursuant to an increase in the number of Shares subject to this Plan approved by
the Board will be exercised prior to the time such increase has been approved by
the stockholders of the Company; and (c) in the event that stockholder approval
of such increase is not obtained within the time period provided herein, all
Awards granted hereunder will be canceled, any Shares issued pursuant to any
Award will be canceled, and any purchase of Shares hereunder will be rescinded.
So long as the Company is subject to Section 16(b) of the Exchange Act, the
Company will comply with the requirements of Rule 16b-3 (or its successor), as
amended, with respect to stockholder approval.

             20. TERM OF PLAN. Unless earlier terminated as provided herein,
this Plan will terminate ten (10) years from the date this Plan is adopted by
the Board or, if earlier, the date of stockholder approval.

             21. AMENDMENT OR TERMINATION OF PLAN. The Board may at any time
terminate or amend this Plan in any respect, including without limitation
amendment of any form of Award Agreement or instrument to be executed pursuant
to this Plan; provided, however, that the Board will not, without the approval
of the stockholders of the Company, amend this Plan in any manner that requires
such stockholder approval pursuant to the Code or the regulations promulgated
thereunder as such provisions apply to ISO plans or (if the Company is subject
to the Exchange Act or Section 16(b) of the Exchange Act) pursuant to the
Exchange Act or Rule 16b-3 (or its successor), as amended, thereunder,
respectively.

             22. NONEXCLUSIVITY OF THE PLAN. Neither the adoption of this Plan
by the Board, the submission of this Plan to the stockholders of the Company for
approval, nor any provision of this Plan will be construed as creating any
limitations on the power of the Board to adopt such additional compensation
arrangements as it may deem desirable, including, without limitation, the
granting of stock options and bonuses otherwise than under this Plan, and such
arrangements may be either generally applicable or applicable only in specific
cases.
