                                HNC SOFTWARE INC.

                           1995 EQUITY INCENTIVE PLAN

                             As Adopted May 4, 1995
                           As Amended December 6, 1996


                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 2,800,000(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 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,

         stock effected in April 1996 and (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.

                                                      1995 Equity Incentive Plan

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;

                (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.

                                                      1995 Equity Incentive Plan



                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.

                         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

                                                               HNC Software Inc.
                                                      1995 Equity Incentive Plan




                         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 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.

                                                               HNC Software Inc.
                                                      1995 Equity Incentive Plan



                         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 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.

                         7.4      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:

                (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 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

                                                      1995 Equity Incentive Plan

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, 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)

                                                      1995 Equity Incentive Plan



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.

                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 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
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

                                                      1995 Equity Incentive 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.

                23.      DEFINITIONS.  As used in this Plan, the following terms
will have the following meanings:

                         "AFFILIATE" means any corporation that directly, or
indirectly through one or more intermediaries, controls or is controlled by, or
is under common control with, another corporation, where "control" (including
the terms "controlled by" and "under common control with") means the possession,
direct or indirect, of the power to cause the direction of the management and
policies of the corporation, whether through the ownership of voting securities,
by contract or otherwise.

                         "AWARD" means any award under this Plan, including any 
Option, Restricted Stock or Stock Bonus.

                         "AWARD AGREEMENT" means, with respect to each Award,
the signed written agreement between the Company and the Participant setting
