                            ------------------------
 
    This Proxy Statement is furnished in connection with the solicitation by the
Board of Directors of CORNERSTONE IMAGING, INC. ("Cornerstone" or the "Company")
of proxies to be voted at the Annual Meeting of Stockholders which will be held
at 9:00 a.m. on June 3, 1998, at the Company's principal executive offices, 1710
Fortune Drive, San Jose, California, or at any adjournments or postponements
thereof, for the purposes set forth in the accompanying Notice of Annual Meeting
of Stockholders. This Proxy Statement and the proxy card were first mailed to
stockholders on or about April 24, 1998.
 
                         VOTING RIGHTS AND SOLICITATION
 
    The close of business on April 14, 1998, was the record date for
stockholders entitled to notice of and to vote at the Annual Meeting. As of that
date, Cornerstone had 7,667,667 shares of common stock, $0.01 par value per
share (the "Common Stock"), issued and outstanding, exclusive of treasury stock.
All of the shares of the Company's Common Stock outstanding on the record date
are entitled to vote at the Annual Meeting, and stockholders of record entitled
to vote at the meeting will have one (1) vote for each share so held on the
matters to be voted upon.
 
    Shares of the Company's Common Stock represented by proxies in the
accompanying form that are properly executed and returned to Cornerstone will be
voted at the Annual Meeting of Stockholders in accordance with the stockholders'
instructions contained therein. In the absence of contrary instructions, shares
represented by such proxies will be voted FOR the election of each of the
directors as described herein under "Proposal 1--Election of Directors," FOR
approval of the amendment to the Cornerstone 1993 Stock Option/Stock Issuance
Plan as described herein under "Proposal 2--Approval of Amendment to the 1993
Stock Option/Stock Issuance Plan," FOR approval of the Cornerstone 1998 Employee
Stock Purchase Plan as described herein under "Proposal 3--Approval of the 1998
Employee Stock Purchase Plan," and FOR ratification of the selection of
accountants as described herein under "Proposal 4-- Ratification of Selection of
Independent Public Accountants." Management does not know of any matters to be
presented at this Annual Meeting other than those set forth in this Proxy
Statement and in the Notice accompanying this Proxy Statement. If other matters
should properly come before the meeting, the proxy holders will vote on such
matters in accordance with their best judgment. Any stockholder has the right to
revoke his or her proxy at any time before it is voted.
 
    The entire cost of soliciting proxies will be borne by Cornerstone. Proxies
will be solicited principally through the use of the mails but, if deemed
desirable, may be solicited personally or by telephone, facsimile or special
letter by officers and regular Cornerstone employees for no additional
compensation. The Company has engaged The First National Bank of Boston ("Bank
of Boston") to provide routine advice and services for proxy distribution and
collection. Bank of Boston will receive approximately $5,000 from the Company
per annum for such advice and services. Arrangements may be made with brokerage
houses and other custodians, nominees and fiduciaries to send proxies and proxy
material to the beneficial owners of the Company's Common Stock, and such
persons may be reimbursed for their expenses.
 
VOTES REQUIRED
 
    PROPOSAL 1.  Directors are elected by a plurality of the affirmative votes
cast by those shares present in person, or represented by proxy, and entitled to
vote at the Annual Meeting. The seven nominees for director receiving the
highest number of affirmative votes will be elected. Abstentions and broker non-
<PAGE>
votes will not be counted toward a nominee's total. Stockholders may not
cumulate votes in the election of directors.
 
    PROPOSAL 2.  Approval of the adoption of the amendment to the Company's 1993
Stock Option/Stock Issuance Plan requires the affirmative vote of a majority of
those shares present in person, or represented by proxy, and entitled to vote at
the Annual Meeting. Abstentions will be treated as votes against the proposal.
Broker non-votes will be treated as not entitled to vote on this matter and thus
will have no effect on the outcome of the vote.
 
    PROPOSAL 3.  Approval of the adoption of the Company's 1998 Employee Stock
Purchase Plan requires the affirmative vote of a majority of those shares
present in person, or represented by proxy, and entitled to vote at the Annual
Meeting. Abstentions will be treated as votes against the proposal. Broker
non-votes will be treated as not entitled to vote on this matter and thus will
have no effect on the outcome of the vote.
 
    PROPOSAL 4.  Ratification of the appointment of Coopers & Lybrand L.L.P. as
the Company's independent public accountants for the fiscal year ending December
31, 1998, requires the affirmative vote of a majority of those shares present in
person, or represented by proxy, and cast either affirmatively or negatively at
the Annual Meeting. Abstentions and broker non-votes will not be counted as
having been voted on the proposal.

    Stockholder proposals intended to be considered at the 1999 Annual Meeting

RECOMMENDATION OF THE BOARD OF DIRECTORS
 
    The Board of Directors recommends that the stockholders vote FOR the
election of each of the above nominees.
 
                                  PROPOSAL 2:
       APPROVAL OF AMENDMENT TO THE 1993 STOCK OPTION/STOCK ISSUANCE PLAN
 
    The stockholders are being asked to vote on a proposal to amend the 1993
Stock Option/Stock Issuance Plan (the "1993 Plan"). The 1993 Plan was amended by
the Board of Directors (the "Board") on March 25, 1998, to increase the number
of shares of Common Stock authorized for issuance thereunder by 200,000 shares
to 2,674,852 shares. The 1993 Plan was adopted by the Board on August 11, 1993,
to be effective on September 8, 1993 (the date of the Company's initial public
offering, the "Effective Date") to
 
                                       4
<PAGE>
provide a means whereby employees, officers, directors, consultants, and
independent advisers of the Company or parent or subsidiary corporations may be
given an opportunity to purchase shares of Common Stock. The Board believes the
amendment is necessary in order to provide the Company with a sufficient reserve
of Common Stock for future option grants needed to attract, employ, and retain
employees, directors, and consultants of outstanding ability.
 
    The principal terms and provisions of the 1993 Plan, as modified by the
recent amendment, are summarized below. The summary, however, does not purport
to be a complete description of all the provisions of the 1993 Plan. Any
stockholder of the Company who wishes to obtain a copy of the actual plan
document may do so by written request to the Corporate Secretary at the
Company's principal executive offices in San Jose.
 
STRUCTURE
 
    The 1993 Plan includes three separate equity incentive programs: (i) a
Discretionary Option Grant Program, under which eligible individuals may be
granted options to purchase shares of Common Stock at an exercise price not less
than 85% of their fair market value on the grant date, (ii) an Automatic Option
Grant Program, under which option grants will automatically be made to eligible
non-employee members of the Board to purchase shares of Common Stock at an
exercise price equal to their fair market value on the grant date, and (iii) a
Stock Issuance Program, under which eligible individuals may be issued shares of
Common Stock directly, through the immediate purchase of the shares or as a
bonus tied to the performance of services or the Company's attainment of
financial objectives, at a price not less than 85% of their fair market value on
the stock issuance date.
 
    Options granted under the Discretionary Option Grant Program may be either
incentive stock options designed to meet the requirements of Section 422 of the
Internal Revenue Code (the "Code") or non-statutory options not intended to
satisfy such requirements. All grants under the Automatic Option Grant Program
will be non-statutory options.
 
SECURITIES SUBJECT TO THE 1993 PLAN
 
    2,474,852 shares of Common Stock have been reserved for issuance over the
ten-year term of the 1993 Plan. If Proposal 2 is approved, that number will
increase by 200,000 shares to 2,674,852 shares. The 1993 Plan has been amended
on several prior occasions, including an amendment to increase the share reserve
by 400,000 shares, approved in 1997.
 
    Shares of Common Stock will be drawn from either the Company's authorized
but unissued shares of Common Stock or from reacquired shares of Common Stock,
including shares repurchased by the Company on the open market. Should an option
(including outstanding options incorporated into the 1993 Plan from the
predecessor plans) expire or terminate for any reason prior to exercise in full
(including options canceled in accordance with the cancellation-regrant
provisions of the 1993 Plan), the shares subject to the portion of the option
not so exercised will be available for subsequent issuance under the 1993 Plan.
Shares subject to any option surrendered or canceled in accordance with the
stock appreciation right provisions of the 1993 Plan and all stock issuances
under the 1993 Plan, whether or not the shares are subsequently reacquired by
the Company pursuant to its repurchase rights under the 1993 Plan, will reduce
on a share-for-share basis the number of shares of Common Stock available for
subsequent issuance.
 
    No individual participating in the 1993 Plan may be granted stock options
and direct stock issuances for more than 500,000 shares of Common Stock in the
aggregate over the term of the 1993 Plan, exclusive of option grants or stock
awards made prior to January 1, 1996.
 
                                       5
<PAGE>
PLAN ADMINISTRATION
 
    The 1993 Plan (other than the Automatic Option Grant Program) is
administered by a committee (the "Committee") comprised of two or more
non-employee Board members appointed by the Board. The Committee has discretion
(subject to the provisions of the 1993 Plan) to authorize stock option grants
and direct stock issuances. The 1993 Plan may be administered with respect to
participants who are not directors by a secondary committee comprised of one or
more Board members or by the full Board. All grants under the Automatic Option
Grant Program will be made in compliance with the provisions of the program, and
no administrative discretion will be exercised with respect to the automatic
grants.
 
    The Committee (or Board or secondary committee to the extent acting as plan
administrator) has full authority (subject to the express provisions of the 1993
Plan) to determine the eligible individuals who are to receive grants under the
1993 Plan and stock awards under the Stock Issuance Program, the number of
shares to be covered by each granted option and stock award, the date or dates
on which each option is to become exercisable, the maximum term for which each
option is to remain outstanding, whether a granted option will be an incentive
stock option ("Incentive Stock Option") which satisfies the requirements of
section 422 of the Code or a non-statutory option not intended to meet such
requirements, and the remaining provisions of the option grant or stock
issuance.
 
ELIGIBILITY
 
    Officers and other employees, non-employee members of the Board who do not
serve on the Committee, and independent consultants and advisors to the Company
(or any parent or subsidiary corporation) are eligible to participate in the
Discretionary Option Grant and Stock Issuance Programs. All non-employee members
of the Board participate in the Automatic Option Grant Program.
 
    As of March 31, 1998, it was estimated that four executive officers and
approximately 200 other employees were eligible to participate in the 1993 Plan
and five non-employee Board members were eligible to participate in the
Automatic Option Grant Program.
 
VALUATION
 
    The fair market value per share of Common Stock on any relevant date under
the 1993 Plan will be the closing price per share on that date on The Nasdaq
National Market ("Nasdaq"). If there is no reported closing price for such date,
then the closing price for the last previous date for which such quotation
exists will be determinative of fair market value. The fair market value of
Common Stock on March 31, 1998, as reported on Nasdaq, was $5.75 per share.

    Under the Discretionary Option Grant Program, the exercise price per share
of Common Stock subject to an Incentive Stock Option may not be less than 100%
of the fair market value per share on the grant date. The exercise price per
share of the Common Stock subject to a non-statutory option may not be less than
85% of the fair market value of that security on the grant date, except that
grants intended to be exempt from the $1 million limitation on compensation
deductions will be made at 100% of fair market value. No option will have a
maximum term in excess of ten years measured from the grant date. The Committee
has discretion to grant options (i) that are immediately exercisable for vested
or unvested shares or (ii) that become exercisable in installments for vested
shares over the optionee's period of service.
 
    The exercise price may be paid in cash or in shares of Common Stock valued
at fair market value on the exercise date. Options may also be exercised through
a same-day sale program, pursuant to which a designated brokerage firm is to
effect the immediate sale of the shares purchased under the option and pay
 
                                       6
<PAGE>
over to the Company, out of the sale proceeds on the settlement date, sufficient
funds to cover the exercise price for the purchased shares plus all applicable
withholding taxes. The Committee may also assist any optionee (including an
officer or director) in the exercise of his or her outstanding options by (a)
authorizing a Company loan to the optionee, or (b) permitting the optionee to
pay the exercise price in installments over a period of years. The terms and
conditions of any such loan or installment payment will be established by the
Committee in its sole discretion.
 
    The Committee will have the authority to effect, on one or more separate
occasions, the cancellation of outstanding options under the Discretionary
Option Grant Program (including outstanding options incorporated from the
predecessor plans) and to issue replacement options with an exercise price based
on the market price of Common Stock at the time of the new grant.
 
TERMINATION OF SERVICE
 
    Any option held by the optionee at the time of cessation of service will
normally not remain exercisable beyond the limited period designated by the
Committee (not to exceed 36 months) at the time of the option grant. During that
period, the option will generally be exercisable only for the number of shares
in which the optionee is vested at the time of cessation of service. Under no
circumstances, however, may any option be exercised after the specified
expiration date of the option term. The Committee may extend the period
following the optionee's cessation of service during which his or her
outstanding options may be exercised and/or to accelerate the exercisability of
such options in whole or in part at any time while the options remain
outstanding.
 
    Any unvested shares of Common Stock will be subject to repurchase by the
Company, at the original exercise price paid per share, upon the optionee's
cessation of service prior to vesting in those shares. The Committee will have
complete discretion in establishing the vesting schedule for any such unvested
shares and will have full authority to cancel the Company's outstanding
repurchase rights with respect to those shares in whole or in part at any time.
 
    The optionee does not have any stockholder rights with respect to the option
shares until the option is exercised and the exercise price is paid for the
purchased shares. Options are not assignable or transferable other than by will
or by the laws of inheritance following the optionee's death, and the option
may, during the optionee's lifetime, be exercised only by the optionee.
 
INCENTIVE STOCK OPTIONS
 
    Incentive Stock Options may only be granted to individuals who are employees
of the Company or its parent or subsidiary corporation. During any calendar
year, the aggregate fair market value (determined as of the grant date(s)) of
the Common Stock for which one or more options granted to any employee under the
1993 Plan (or any other option plan of the Company or its parent or subsidiary
corporations) may for the first time become exercisable as Incentive Stock
Options cannot exceed $100,000.
 
TANDEM STOCK APPRECIATION RIGHTS
 
    The Committee is authorized to issue tandem stock appreciation rights in
connection with option grants under the Discretionary Option Grant Program.
Tandem stock appreciation rights provide the holders with the right to surrender
their options for an appreciation distribution from the Company equal in amount
to the excess of (i) the fair market value of the vested shares of Common Stock
subject to the surrendered option over (ii) the aggregate exercise price payable
for such vested shares. Such appreciation distribution may, in the discretion of
the Committee, be made in cash or in shares of Common Stock.
 
                                       7
<PAGE>
LIMITED STOCK APPRECIATION RIGHTS
 
    Officers of the Company subject to the short-swing profit restrictions of
the Federal securities laws may be granted limited stock appreciation rights in
connection with their option grants, at the discretion of the Committee. Any
option with such a limited stock appreciation right in effect for at least six
months may be surrendered to the Company upon the successful completion of a
hostile tender offer for securities possessing more than 50% of the combined
voting power of the Company's outstanding securities. In return for the
surrendered option, the officer will be entitled to a cash distribution from the
Company in an amount per vested share of Common Stock subject to the surrendered
option equal to the excess of (i) the price per share of Common Stock paid in
such hostile tender offer over (ii) the option exercise price.
 
                         AUTOMATIC OPTION GRANT PROGRAM
 
    Under the Automatic Option Grant Program, each individual who was serving as
a non-employee Board member on November 5, 1993, was automatically granted a
non-statutory option to purchase 10,000 shares of Common Stock. In addition,
each individual who first becomes a non-employee Board member after November 5,
1993, whether through election by the Company's stockholders or appointment by
the Board, will automatically be granted at the time of such election or
appointment a non-statutory option to purchase 10,000 shares of Common Stock. On
the date of each Annual Stockholders Meeting, beginning with the 1995 Annual
Meeting, each individual who is then serving as a non-employee Board member,
whether or not standing for re-election at that meeting, will automatically be
granted a non-statutory option to purchase 2,500 shares of Common Stock,
provided such individual has served as a Board member for at least six months.
No non-employee Board member who has previously been in the employ of the
Company or any parent or subsidiary corporation will be eligible to receive an
automatic option grant.
 
    The exercise price per share of the Common Stock subject to an automatic
option grant will equal the fair market value per share of Common Stock on the
automatic grant date. Each option will have a term of ten years measured from
the grant date. Each 10,000-share option will become exercisable for the option
shares in a series of four equal annual installments over the first four years
of the optionee's period of Board service. Each 2,500-share option will become
exercisable for the option shares on the fourth anniversary of the automatic
grant date provided the optionee remains in Board service. The option will
remain exercisable for a three-month period following the optionee's cessation
of Board service for any reason other than death and for a twelve-month period
following death. In no event, however, may the option be exercised after the
expiration date of the option term. During the applicable exercise period, the
option may not be exercised for more than the number of shares (if any) in which
the optionee is vested at the time of the optionee's cessation of Board service.
However, should the optionee die while serving as a Board member and holding one
or more automatic option grants that had been outstanding for at least one year,
then each such option will become fully vested and remain exercisable for a
twelve-month period following such optionee's death and may be exercised by the
personal representative of the optionee's estate or the person to whom the grant
is transferred by the optionee's will or the laws of inheritance.
 
    Each automatic option grant will become exercisable in full upon the
occurrence of certain changes in control or ownership of the Company, as
explained in more detail below in the subsection entitled "Option/Vesting
Acceleration." Upon the successful completion of a hostile tender offer for
securities possessing more than 50% of the combined voting power of the
Company's outstanding securities, each automatic option grant that has been
outstanding for at least six months may be surrendered to the Company for a cash
distribution per surrendered option share in an amount equal to the excess of
(i) the price per share of Common Stock paid in such tender offer over (ii) the
exercise price payable for such share.

<PAGE>
                             STOCK ISSUANCE PROGRAM
 
    Shares may be sold under the Stock Issuance Program at a price per share not
less than 85% of the fair market value, payable in cash or through a promissory
note payable to the Company, or as a bonus for past services. Shares issued
under the Stock Issuance Program may either be vested upon issuance or subject
to a vesting schedule tied to the participant's period of service or the
attainment of designated performance goals. Unvested shares will be subject to
certain transfer restrictions and to repurchase or cancellation by the Company
upon either the participant's cessation of service prior to vesting in those
shares or the non-attainment of the applicable performance goals. The Committee
has discretion to accelerate the vesting of any issued shares in whole or in
part at any time. Individuals holding shares under the Stock Issuance Program
will have full stockholder rights with respect to those shares, whether the
shares are vested or unvested.
 
                               GENERAL PROVISIONS
 
OPTION/VESTING ACCELERATION
 
    Outstanding options under the 1993 Plan will become immediately exercisable
in full, and unvested shares issued under the 1993 Plan will become fully
vested, in the event of certain changes in the ownership or control of the
Company. The transactions that will trigger such option/vesting acceleration are
as follows:
 
    CORPORATE TRANSACTION:  any one of the following stockholder-approved
transactions:
 
    - a merger or consolidation in which the Company is not the surviving
      entity, except for a transaction the principal purpose of which is to
      change the state in which the Company is incorporated,
 
    - the sale, transfer or other disposition of all or substantially all of the
      Company's assets in complete liquidation or dissolution of the Company, or
 
    - any reverse merger in which the Company is the surviving entity but in
      which securities possessing more than 50% of the total combined voting
      power of the Company's outstanding securities are transferred to a person
      or persons different from those who held such securities immediately prior
      to the merger.
 
    CHANGE IN CONTROL:  a change in ownership or control of the Company effected
through either of the following transactions:
 
    - any person or related group of persons (other than the Company or a person
      that directly or indirectly controls, is controlled by, or is under common
      control with, the Company) directly or indirectly acquires beneficial
      ownership (within the meaning of Rule 13d-3 of the Securities and Exchange
      Act of 1934, as amended) of securities possessing more than 50% of the
      total combined voting power of the Company's outstanding securities
      pursuant to a tender or exchange offer made directly to the Company's
      stockholders, which the Board does not recommend such stockholders to
      accept; or
 
    - a change in the composition of the Board over a period of 36 consecutive
      months or less such that a majority of the Board members (rounded up to
      the next whole number) ceases, by reason of one or more contested
      elections for Board membership, to be comprised of individuals who either
      (i) have been Board members continuously since the beginning of such
      period or (ii) have been elected or nominated for election as Board
      members during such period by at least a majority of the Board members
      described in clause (i) who were still in office at the time such election
      or nomination was approved by the Board.
 
    Immediately following the consummation of a Corporate Transaction, all
outstanding options under the 1993 Plan will, to the extent not previously
exercised by the optionees or assumed by the successor
 
                                       9
<PAGE>
corporation (or its parent company), terminate and cease to be exercisable.
Options under the 1993 Plan that are accelerated in connection with a Change in
Control will remain so exercisable until the expiration or sooner termination of
the option term.
 
    Certain outstanding stock options under the predecessor plans that were
incorporated into the 1993 Plan do not contain any automatic acceleration
provisions that would allow the option to become immediately exercisable upon a
Corporate Transaction or change in control of the Company, and certain other
such incorporated options will accelerate on an acquisition subject to certain
limitations. The Committee has discretion to extend the automatic acceleration
provisions of the 1993 Plan to any or all stock options incorporated from the
predecessor plans.
 
    The acceleration of options or vesting of shares in the event of a Corporate
Transaction or Change in Control may be seen as an anti-takeover provision and
may have the effect of discouraging a merger proposal, a takeover attempt or
other efforts to gain control of the Company.
 
CHANGES IN CAPITALIZATION
 
    In the event any change is made to the outstanding shares of Common Stock by
reason of any recapitalization, stock dividend, stock split, combination of
shares, exchange of shares or other change in corporate structure effected
without the Company's receipt of consideration, appropriate adjustments will be
made to (i) the maximum number and/or class of securities issuable under the
1993 Plan, (ii) the maximum number and/or class of securities for which any one
individual may be granted stock options and direct share issuances in the
aggregate over the term of the 1993 Plan, (iii) the number and/or class of
securities and price per share in effect under each outstanding option,
including options from the predecessor plans incorporated into the 1993 Plan,
and (iv) the number and/or class of securities for which automatic option grants
will subsequently be made under the Automatic Option Grant Program per non-
employee Board member.
 
SPECIAL TAX ELECTION
 
    The Committee may provide one or more holders of non-statutory options or
unvested shares under the Discretionary Option Grant or Stock Issuance Program
with the right to have the Company withhold a portion of the shares of Common
Stock otherwise issuable to such individuals in satisfaction of the Federal,
state and local income and employment tax liability incurred by such individuals
in connection with the exercise of those options or the vesting of the shares.
Alternatively, the Committee may allow such individuals to deliver previously
acquired shares of Common Stock in payment of such tax liability.
 
AMENDMENT AND TERMINATION
 
    The Board may amend or modify the 1993 Plan in any or all respects
whatsoever. However, no such amendment may adversely affect the rights of
existing optionees or holders of unvested shares without their consent. In
addition, the Board may not, without the approval of the Company's stockholders,
(i) materially increase the maximum number of shares issuable under the 1993
Plan (except in connection with certain changes in the Company's capital
structure), (ii) materially modify the eligibility requirements for option
grants or share issuances or (iii) otherwise materially increase the benefits
accruing to participants under the 1993 Plan.
 
    Unless sooner terminated by the Board, the 1993 Plan will in all events
terminate on August 10, 2003. Each stock option or unvested share issuance
outstanding at the time of such termination will remain in force in accordance
with the provisions of the instruments evidencing such grant or issuance.
 
    As of March 31, 1998, options covering 1,699,320 shares were outstanding
under the 1993 Plan, 466,696 shares remained available for future grants
assuming approval of Proposal 2, and 526,373 shares
 
                                       10
<PAGE>
have been issued under the 1993 Plan. The expiration dates for all such options
range from April 4, 1998 to March 31, 2008.
 
NEW PLAN BENEFITS
 
    Because the 1993 Plan is discretionary, benefits to be received by
individual optionees are not determinable. However, each of Messrs. Crawford,
Silver and Tompkins and Dr. Crockett and Dr. Sheafor will receive an option
grant to purchase 2,500 shares under the Automatic Option Grant Program on the
date of the Annual Meeting with an exercise price per share equal to the closing
price per share of Common Stock on the date of the Annual Meeting.
 
FEDERAL INCOME TAX CONSEQUENCES OF OPTIONS GRANTED UNDER THE 1993 PLAN
 
    Options granted under the 1993 Plan may be either incentive stock options
that satisfy the requirements of Section 422 of the Internal Revenue Code or
non-statutory options that are not intended to meet such requirements. The
Federal income tax treatment for the two types of options differs as follows:
 
    INCENTIVE STOCK OPTIONS.  No taxable income is recognized by the optionee at
the time of the option grant, and no taxable income is generally recognized at
the time the option is exercised. However, the amount by which the fair market
value (at the time of exercise) of the purchased shares exceeds the exercise
price paid for those shares will constitute an adjustment to income for purposes
of the alternative minimum tax. The optionee will, however, recognize taxable
income in the year in which the purchased shares are sold or otherwise made the
subject of disposition. For Federal tax purposes, dispositions are divided into
two categories: (i) qualifying and (ii) disqualifying. The optionee will make a
qualifying disposition of the purchased shares if the sale or other disposition
of such shares is made after the optionee has held the shares for more than two
(2) years after the grant date of the option and more than one (1) year after
the exercise date. If the optionee fails to satisfy either of these two holding
periods prior to the sale or other disposition of the purchased shares, then a
disqualifying disposition will result.
 
    Upon a qualifying disposition of the shares, the optionee will recognize
long-term or medium-term capital gain in an amount equal to the excess of (i)
the amount realized upon the sale or other disposition of the purchased shares
over (ii) the exercise price paid for such shares. If there is a disqualifying
disposition of the shares, then generally the excess of (i) the fair market
value of those shares on the date the option was exercised over (ii) the
exercise price paid for the shares will be taxable as ordinary income. Any
additional gain recognized upon the disposition will be a capital gain.
 
    If the optionee makes a disqualifying disposition of the purchased shares,
then the Company will be entitled to an income tax deduction for the taxable
year in which such disposition occurs equal to the impact of ordinary income
recognized by the optionee. In no other instance will the Company be allowed a
deduction with respect to the optionee's disposition of the purchased shares.
The Company anticipates that any compensation deemed paid by the Company upon
one or more disqualifying dispositions of incentive stock option shares by the
Company's executive officers will remain deductible by the Company and will not
have to be taken into account for purposes of the $1 million limitation per
covered individual on the deductibility of the compensation paid to certain
executive officers of the Company.
 
    NON-STATUTORY OPTIONS.  No taxable income is recognized by an optionee upon
the grant of a non-statutory option. The optionee will in general recognize
ordinary income in the year in which the option is exercised equal to the excess
of the fair market value of the purchased shares on the exercise date over the
exercise price paid for the shares, and the optionee (if an employee or former
employee) will be required to satisfy the tax withholding requirements
applicable to such income.
 
                                       11
<PAGE>
    Special provisions of the Internal Revenue Code apply to the acquisition of
Common Stock under a non-statutory option if the purchased shares are subject to
repurchase by the Company. These special provisions may be summarized as
follows:
 
        (i) If the shares acquired upon exercise of the non-statutory option are
    subject to repurchase by the Company at the original exercise price in the
    event of the optionee's termination of service prior to vesting in such
    shares, the optionee will not recognize any taxable income at the time of
    exercise but will have to report as ordinary income, as and when the
    Company's repurchase right lapses, an amount equal to the excess of (a) the
    fair market value of the shares on the date such repurchase right lapses
    with respect to such shares over (b) the exercise price paid for the shares.
 
        (ii) The optionee may, however, elect under Section 83(b) of the
    Internal Revenue Code to include as ordinary income in the year of exercise
    of the non-statutory option an amount equal to the excess of (a) the fair
    market value of the purchased shares on the exercise date (determined as if
    the shares were not subject to the Company's repurchase right) over (b) the
    exercise price paid for such shares. If the Section 83(b) election is made,
    the optionee will not recognize any additional income as and when the
    repurchase right lapses.
 
    The Company will be entitled to a business expense deduction equal to the
amount of ordinary income recognized by the optionee with respect to the
exercised non-statutory option. The deduction will in general be allowed for the
taxable year of the Company in which such ordinary income is recognized by the
optionee. The Company anticipates that the compensation deemed paid by the
Company upon the exercise of non-statutory options with exercise prices equal to
the fair market value of the option shares on the grant date will remain
deductible by the Company and will not have to be taken into account for
purposes of the $1 million limitation per covered individual on the
deductibility of the compensation paid to certain executive officers of the
Company.
 
    STOCK APPRECIATION RIGHTS.  An optionee who is granted a stock appreciation
right will recognize ordinary income in the year of exercise equal to the amount
of the appreciation distribution. The Company will be entitled to a business
expense deduction equal to the appreciation distribution for the taxable year of
the Company in which the ordinary income is recognized by the optionee.
 
    STOCK ISSUANCES.  The tax principles applicable to direct stock issuances
under the 1993 Plan will be substantially the same as those summarized above for
the exercise of nonstatutory option grants.
 
STOCKHOLDER APPROVAL
 
    The affirmative vote of a majority of the outstanding voting shares of the
Company present or represented and entitled to vote on Proposal 2 at the 1998
Annual Meeting is required for approval of the amendment to the 1993 Plan.
SHOULD SUCH STOCKHOLDER APPROVAL NOT BE OBTAINED, THEN THE AMENDMENT TO THE 1993
PLAN WILL NOT BECOME EFFECTIVE, AND ALL OUTSTANDING OPTIONS GRANTED ON THE BASIS
OF THE 200,000 SHARE INCREASE WILL TERMINATE WITHOUT EVER BECOMING EXERCISABLE
FOR ANY OF THE OPTION SHARES.
 
RECOMMENDATION OF THE BOARD OF DIRECTORS
 
    The Board of Directors recommends that the stockholders vote FOR the
approval of the amendment to the 1993 Plan.
 
                                  PROPOSAL 3:
               APPROVAL OF THE 1998 EMPLOYEE STOCK PURCHASE PLAN
 
    The stockholders are being asked to vote on a proposal to approve the 1998
Employee Stock Purchase Plan (the "ESPP"). The Board of Directors adopted the
ESPP in March of 1998 to provide employees of the Company with an opportunity to
purchase Common Stock through payroll deductions. The principal
 
                                       12
<PAGE>
provisions of the ESPP are summarized below. The summary, however, does not
purport to be a complete description of the ESPP. Any stockholder who would like
to obtain a copy of the plan text may request one in writing from the Corporate
Secretary at the Company's principal offices in San Jose.
 
SUMMARY OF ESPP
 
    The ESPP becomes effective on July 1, 1998, and replaces an employee stock
purchase plan that the Company maintained since 1993. Under the ESPP, 50,000
shares of Common Stock are available for issuance during each semi-annual
accumulation period. Shares that are not used during a semi-annual accumulation
period may not be carried forward to any subsequent accumulation period. The
aggregate of 100,000 shares are available for issuance during the life of the
Plan. All full-time regular employees who have completed at least 30 days of
service (approximately 200 individuals) will be eligible to participate in the
ESPP.
 
    Eligible employees may contribute up to 10% of their base salaries to the
ESPP. Amounts withheld are applied at the end of every six-month accumulation
period to purchase shares of Common Stock, but not more than 1,000 shares per
accumulation period. The value of the Common Stock (determined as of the
beginning of the offering period) that may be purchased by any participant in a
calendar year is limited to $25,000. The closing price of Common Stock was $5.75
per share on March 31, 1998. Participants may withdraw their contributions at
any time before stock is purchased.
 
    The purchase price is equal to 85% of the lower of (a) the market price of
Common Stock immediately before the beginning of the applicable offering period
or (b) the market price of Common Stock at the time of the purchase. In general,
each offering period is 24 months long, but a new offering period begins every
six months. Thus up to four overlapping offering periods may be in effect at the
same time. An offering period continues to apply to a participant for the full
24 months, unless the market price of Common Stock is lower when a subsequent
offering period begins. In that event, the subsequent offering period
automatically becomes the applicable period for purposes of determining the
purchase price.
 
    The Board of Directors may amend any provision of the ESPP. Amendments do
not require stockholder approval, unless the aggregate number of shares of
Common Stock available for purchase under the ESPP is increased. The ESPP may be
terminated at any time by the Board of Directors.
 
NEW PLAN BENEFITS
 
    Since purchase rights are subject to discretion, including an employee's
decision not to participate in the ESPP, awards under the ESPP for the current
fiscal year are not determinable. No purchase rights have been granted to date
under the ESPP.
 
FEDERAL INCOME TAX CONSEQUENCES
 
    The following is a general description of certain federal income tax
consequences of the ESPP. This description does not purport to be complete.
 
    The ESPP is intended to qualify as an "employee stock purchase plan" under
section 423 of the Code. No income is recognized by a participant at the time a
right to purchase shares is granted. Likewise, no taxable income is recognized
at the time of the purchase, even though the purchase price reflects a discount
from the market value of the shares at that time.
 
    A participant must recognize taxable income upon a disposition of shares
acquired under the ESPP. The tax treatment may be more favorable if the
disposition occurs after the holding-period requirements of section 423 have
been satisfied (a "qualifying disposition"). To satisfy the holding-period
requirements of section 423, shares acquired under the ESPP cannot be disposed
of within two years after the first day of
 
                                       13
<PAGE>
the offering period during which the shares were purchased nor within one year
after the shares were purchased. The U.S. income tax consequences of a
qualifying disposition are as follows:
 
    The participant recognizes ordinary income equal to the lower of (a) the
excess of the fair market value of the shares on the date of the disposition
over the purchase price or (b) 15% of the fair market value of the shares on the
first day of the applicable offering period. The Company will not be entitled to
any deduction under these circumstances. The excess, if any, of the fair market
value of the shares on the date of the disposition over the sum of the purchase
price plus the amount of ordinary income recognized (as described above) will be
taxed as a medium-term or long-term capital gain. If a taxable disposition
produces a loss (i.e., the fair market value of the shares on the date of the
disposition is less than the purchase price) and the disposition involves
certain unrelated parties, then the loss will be a capital loss.
 
    A participant who disposes of shares acquired under the ESPP without meeting
the holding-period requirements makes a disqualifying disposition of such
shares. The U.S. income tax consequences of a disqualifying disposition are as
follows:
 
    The entire difference between the purchase price and the market value of the
shares on the date of purchase will be taxed to the participant as ordinary
income in the year of disposition. The Company will be entitled to a deduction
for the same amount, subject to certain conditions. The excess, if any, of the
market value of the shares on the date of disposition over their market value on
the date of purchase will be taxed as a capital gain (long-term or short term,
depending on how long the shares have been held). If the value of the shares on
the date of disposition is less than their value on the date of purchase, then
the difference will result in a capital loss (long-term, medium-term or
short-term, depending on the holding period), provided the disposition involves
certain unrelated parties. Any such loss will not affect the ordinary income
recognized upon the disposition.
 
RECOMMENDATION OF THE BOARD OF DIRECTORS
 
    The Board of Directors recommends that the stockholders vote FOR the
approval of the ESPP.
 
                                  PROPOSAL 4:
          RATIFICATION OF SELECTION OF INDEPENDENT PUBLIC ACCOUNTANTS
 
    The firm of Coopers & Lybrand L.L.P. served as independent public
accountants for the Company for the fiscal year ended December 31, 1997. The
Board of Directors desires the firm to continue in this capacity for the current
fiscal year. Accordingly, a resolution will be presented to the meeting to
ratify the selection of Coopers & Lybrand L.L.P. by the Board of Directors as
independent public accountants to audit the accounts and records of the Company
for the fiscal year ending December 31, 1998, and to perform other appropriate
services. In the event that stockholders fail to ratify the selection of Coopers
& Lybrand L.L.P., the Board of Directors would reconsider such selection. Even
if the selection is ratified, the Board of Directors in its discretion may
direct the appointment of a different independent auditing firm at any time
during the year if the Board of Directors believes that such a change would be
in the best interests of the Company and its stockholders.
 
    A representative of Coopers & Lybrand L.L.P. will be present at the Annual
Meeting to respond to appropriate questions and to make a statement if such
representative desires to do so.
 
RECOMMENDATION OF THE BOARD OF DIRECTORS
 
    The Board of Directors recommends that the stockholders vote FOR the
ratification of the selection of Coopers & Lybrand L.L.P. to serve as the
Company's independent auditors for the fiscal year ending December 31, 1998.

      COMPLIANCE WITH SECTION 16(a) OF THE SECURITIES EXCHANGE ACT OF 1934
 
    Section 16(a) of the Securities Exchange Act of 1934 requires the Company's
directors, executive officers and persons who own more than ten percent of a
registered class of the Company's equity securities to file with the Securities
and Exchange Commission (the "SEC") initial reports of ownership and reports of
changes in ownership of Common Stock and other equity securities of the Company.
Officers, directors and greater than ten percent beneficial owners are required
by SEC regulation to furnish the Company with copies of all Section 16(a)
reports they file.
 
    Based solely upon review of the copies of such reports furnished to the
Company and written representations that no other reports were required, the
Company believes that, except as further described below, there was compliance
for the fiscal year ended December 31, 1997, with all Section 16(a) filing
requirements applicable to the Company's officers, directors and greater than
ten percent beneficial owners except that Kenneth E. Westrick, the Company's
former Vice President and General Manager of Display Products filed one late
report regarding a single transaction and E. David Crockett, the Chairman of the
Company's Board of Directors, filed one late report regarding a single
transaction.

</TABLE>
 
- ------------------------
 
(1) The options listed in the table were granted under the 1993 Stock
    Option/Stock Issuance Plan. For a complete description of the 1993 Plan, see
    Proposal 2. All of the options granted on February 14, 1997 become
    exercisable as follows: 25% upon the completion of each of the first and
    second years of service measured from the vesting date, and an additional
    6.25% upon the completion of each full calendar quarter elapsed thereafter,
    until the option is fully vested upon the completion of the fourth year of
    service from the vesting date. All of the options granted on November 13,
    1997 become exercisable as follows: 40% upon the completion of each of the
    first year of service measured from the vesting date, and an additional 5%
    upon the completion of each full calendar quarter elapsed thereafter, until
    the option is fully vested upon the completion of the fourth year of service
    from the vesting date. The options were granted and began vesting on the
    date 10 years before the expiration date set forth in the table. Each option
    will become exercisable and then terminate in the event the Company is
    acquired by a merger or in the event of a liquidation or acquisition of the
    Company, except that the option does not terminate if it is assumed by the
    acquiring entity. Each option has a maximum term of 10 years, subject to
    earlier termination in the event of the optionee's cessation of service with
    the Company.
 
(2) The exercise price of each option may be paid in cash, in shares of Common
    Stock valued at fair market value on the exercise date or through a cashless
    exercise procedure involving a same-day sale of the purchased shares. The
    Company may also finance the option exercise by loaning the optionee
    sufficient funds to pay the exercise price for the purchased shares and the
    federal and state tax liability incurred in connection with such exercise.
    The optionee may be permitted, subject to the approval of the plan
    administrator, to apply a portion of the shares purchased under the option
    (or to deliver existing shares of Common Stock) in satisfaction of such tax
    liability. The plan administrator also has the authority to reprice
    outstanding options through the cancellation of those options and the grant
    of replacement options with an exercise price equal to the fair market value
    of the option shares on the regrant date.
 
(3) The five percent (5%) and ten percent (10%) assumed annual rates of
    compounded stock price appreciation are mandated by the rules of the
    Securities and Exchange Commission. There is no assurance provided to any
    executive officer or any other holder of the Company's securities that the
    actual stock price appreciation over the 10-year option term will be at the
    assumed 5% and 10% levels or at any other defined level. Unless the market
    price of the Common Stock does in fact appreciate over the option term, no
    value will be realized from the option grants.

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION
 
    No member of the Compensation Committee is a former or current officer or
employee of the Company or any of its subsidiaries. No executive officer of the
Company serves as a member of the board of directors or compensation committee
of any entity that has one or more executive officers serving as a member of the
Company's Board of Directors or Compensation Committee.
 
                      REPORT OF THE COMPENSATION COMMITTEE
 
    The following is the Report of the Compensation Committee of the Board of
Directors, describing the compensation policies and rationale applicable to the
Company's executive officers with respect to the compensation paid to such
executive officers for the year ended December 31, 1997.
 
PURPOSE OF THE COMPENSATION COMMITTEE
 
    The Committee is responsible for determining compensation levels for the
executive officers for each fiscal year based upon a consistent set of policies
and procedures.
 
COMMITTEE STRUCTURE
 
    The Committee is made up of two independent, non-employee members of the
Board of Directors who meet during the first quarter of each fiscal year to set
executive officer salaries, and as needed thereafter. No prior or current member
of the Committee has any interlocking relationships as defined by the SEC.
 
                                       19
<PAGE>
OBJECTIVES OF THE COMPENSATION PROGRAM
 
    The objectives of the compensation program are: (1) to provide a means for
the Company to attract and retain high-quality executives; (2) to tie executive
compensation directly to the Company's business and performance objectives; and
(3) to reward outstanding individual performance that contributes to the
long-term success of the Company.
 
ELEMENTS OF COMPENSATION
 
    Each executive officer's compensation package is comprised of three
elements: (1) base compensation, which reflects individual performance and is
designed primarily to be competitive with salary levels in a comparative group,
(2) annual bonus plan compensation payable in cash and tied to the achievement
of financial performance goals established by the Committee, and (3) long-term
stock-based incentive compensation which emphasizes a focus on Company growth
and increased stockholder value.
 
BASE COMPENSATION
 
    The base compensation for each executive officer is determined using an
analysis of competitive salary ranges provided by an independent public
accounting firm which focuses on companies similar in size and business who
compete with Cornerstone in the recruitment and retention of senior personnel.
The Committee believes that the Company's most direct competitors for executive
talent are not necessarily all of the companies that the Company would use in a
comparison of stockholder returns. Therefore, the compensation comparison group
is not the same as the industry group in the index used in the PERFORMANCE
GRAPH, below.
 
    The Committee considers specifically the following factors in determining
base compensation: (1) a comparison of the Company's growth and financial
performance relative to the performance of competitors, (2) salary levels for
comparable positions in the compensation comparison group and (3) each
executive's responsibility level and financial and strategic objectives for the
subsequent year. The Committee believes that the current base compensation for
executive officers is at the low end of the companies in the compensation
comparison group with which the Company competes for talent.
 
ANNUAL BONUS PLAN COMPENSATION
 
    The Company's annual bonus plan provides for incentive bonus compensation to
all officers and a number of key employees based on the achievement of specific
corporate performance targets established at the beginning of the fiscal year
relating to revenues and operating profits. For fiscal year 1997, a bonus range
was established such that achievement of planned revenue and operating profits
would result in a specified bonus level. For performance levels over plan, the
bonus compensation amount would increase proportionately. For fiscal year 1997,
revenue and operating profits were below established targets. The Committee
concluded that based on the return to profitability after significant first
quarter losses, the executive officers' performances warrant the bonus
compensation for 1997 as reflected in the SUMMARY COMPENSATION TABLE above.
 
    The Company's incentive bonus compensation structure was reviewed and
revised for fiscal year 1997 to include specific corporate performance targets
relating to revenues and net profits as well as specific individual performance
objectives.
 
LONG-TERM STOCK-BASED INCENTIVE COMPENSATION
 
    Long-term incentives are provided through stock option grants. The grants
are designed to align the interests of each executive officer with those of the
stockholders and provide each individual with a significant incentive to manage
the Company from the perspective of an owner with an equity stake in the
business. Each grant generally allows the officer to acquire shares of the
Company's common stock at a
 
                                       20
<PAGE>
fixed price per share (the market price on the grant date) over a specified
period of time (up to 10 years). Each option generally becomes exercisable in
installments over a four year period, contingent upon the executive officer's
continued employment with the Company. Accordingly, the option will provide a
return to the executive officer only if the executive officer remains employed
by the Company during the four year vesting period, and then only if the market
price of the shares appreciates over the option term. The size of the option
grant to each executive officer, based on the aggregate exercise price,
generally is set to a multiple of salary that the Committee deems appropriate in
order to create a meaningful opportunity for stock ownership based upon the
individual's current position with the Company, but also takes into account
comparable awards to individuals in similar positions in the industry as
reflected in external surveys, the individual's potential for future
responsibility and promotion over the option term and the individual's personal
performance in recent periods. The Committee also takes into account the number
of vested and unvested options held by the executive officer in order to
maintain an appropriate amount of equity incentive for that individual. The
weight of these various factors will vary over time and with respect to each
individual. However, the Committee does not adhere to any specific guidelines as
to the relative option holdings of the Company's executive officers.
 
CHIEF EXECUTIVE OFFICER'S COMPENSATION
 
    Compensation for the Chief Executive Officer is determined by a process
similar to that discussed above for executive officers. Mr. van Overbeek's base
compensation for fiscal 1997 was established by the Board of Directors in 1994
and was increased by the Committee effective September 30, 1995. The Committee
established Mr. van Overbeek's base salary adjustment based on an evaluation of
his personal performance and the objective of having his base salary keep pace
with salaries being paid to similarly situated chief executive officers.
Further, the Committee intends base salary to provide Mr. van Overbeek with a
level of stability and certainty each year and intends that this particular
component of compensation not be affected to any significant degree by Company
performance factors.
 
    The remaining components of Mr. van Overbeek's 1997 compensation, however,
were dependent upon financial performance and provided no dollar guarantees. The
incentive bonus compensation for Mr. van Overbeek for the 1997 fiscal year was
initially dependent on the achievements of specific corporate performance
targets established at the beginning of the fiscal year, as set forth above.
While revenue and operating profits were below established targets, upon
discretionary review by the Compensation Committee, Mr. van Overbeek was awarded
his bonus listed in the SUMMARY COMPENSATION TABLE above, based on the Company's
return to profitability in the fourth quarter, after a loss in the second
quarter as well as achieving profitability in the Company's Software Division in
the second half of fiscal 1997.
 
DEDUCTION LIMIT FOR EXECUTIVE COMPENSATION
 
    Section 162(m) of the Internal Revenue Code, enacted in 1993, limits federal
income tax deductions for compensation paid to the Chief Executive Officer and
the four other most highly compensated officers of a public company to $1
million per year, but contains an exception for performance-based compensation
that satisfies certain conditions.
 
    The Committee believes that option grants under the 1993 Plan are exempt
from the deduction limit. Because it is unlikely that other compensation payable
to any Company executive would exceed the deduction limit in the near future,
the Committee has not yet considered whether it will seek to qualify
compensation other than options for the performance-based exception or will
prohibit the payment of compensation that would exceed the deduction limit.
However, in approving the amount and form of compensation for Company
executives, the Committee will continue to consider all elements of cost to the
Company of providing that compensation.

                           CORNERSTONE IMAGING, INC.
                       1998 EMPLOYEE STOCK PURCHASE PLAN


SECTION 1.  PURPOSE OF THE PLAN.

     The Plan was adopted by the Board on March 25, 1998, effective as of 
July 1, 1998.  The purpose of the Plan is to provide Eligible Employees with 
an opportunity to increase their proprietary interest in the success of the 
Company by purchasing Stock from the Company on favorable terms and to pay 
for such purchases through payroll deductions.  The Plan is intended to 
qualify under section 423 of the Code.

SECTION 2.  ADMINISTRATION OF THE PLAN.

     (a)  COMMITTEE COMPOSITION.  The Plan shall be administered by the 
Committee. The Committee shall consist exclusively of one or more directors 
of the Company, who shall be appointed by the Board.

     (b)  COMMITTEE RESPONSIBILITIES.  The Committee shall interpret the Plan 
and make all other policy decisions relating to the operation of the Plan.  
The Committee may adopt such rules, guidelines and forms as it deems 
appropriate to implement the Plan.  The Committee's determinations under the 
Plan shall be final and binding on all persons.

SECTION 3.  ENROLLMENT AND PARTICIPATION.

     (a)  OFFERING PERIODS.  While the Plan is in effect, two overlapping 
Offering Periods shall commence in each calendar year.  The Offering Periods 
shall consist of the 24-month periods commencing on each January 1 and July 1.

     (b)  ACCUMULATION PERIODS.  While the Plan is in effect, two 
Accumulation Periods shall commence in each calendar year.  The Accumulation 
Periods shall consist of the six-month periods commencing on each January 1 
and July 1.

     (c)  ENROLLMENT.  Any individual who, on the day preceding the first day 
of an Offering Period, qualifies as an Eligible Employee may elect to become 
a Participant in the Plan for such Offering Period by executing the 
enrollment form prescribed for this purpose by the Committee.  The enrollment 
form shall be filed with the Company at the prescribed location not later 
than 10 days prior to the commencement of such Offering Period.

     (d)  DURATION OF PARTICIPATION.  Once enrolled in the Plan, a 
Participant shall continue to participate in the Plan until he or she ceases 
to be an Eligible Employee, withdraws from the Plan under Section 5(a) or 
reaches the end of the Accumulation Period in which his or her employee 
contributions were discontinued under Section 4(d) or 8(b).  A Participant 
who discontinued employee contributions under Section 4(d) or withdrew from 
the Plan under 

<PAGE>

Section 5(a) may again become a Participant, if he or she then is an Eligible 
Employee, by following the procedure described in Subsection (c) above.  A 
Participant whose employee contributions were discontinued automatically 
under Section 8(b) shall automatically resume participation at the beginning 
of the earliest Accumulation Period ending in the next calendar year, if he 
or she then is an Eligible Employee.

     (e)  APPLICABLE OFFERING PERIOD.  For purposes of calculating the 
Purchase Price under Section 7(b), the applicable Offering Period shall be 
determined as follows:

          (i)   Once a Participant is enrolled in the Plan for an Offering
     Period, such Offering Period shall continue to apply to him or her
     until the earliest of (A) the end of such Offering Period, (B) the
     end of his or her participation under Subsection (d) above or
     (C) re-enrollment for a subsequent Offering Period under Paragraph (ii) or
     (iii) below.

          (ii)  In the event that the Fair Market Value of Stock on the last
     trading day before the commencement of the Offering Period for which
     the Participant is enrolled is higher than on the last trading day
     before the commencement of any subsequent Offering Period, the
     Participant shall automatically be re-enrolled for such subsequent
     Offering Period.

          (iii) Any other provision of the Plan notwithstanding, the Company
     (at its sole discretion) may determine prior to the commencement of any
     new Offering Period that all Participants shall be re-enrolled for
     such new Offering Period.

          (iv)  When a Participant reaches the end of an Offering Period but
     his or her participation is to continue, then such Participant shall
     automatically be re-enrolled for the Offering Period that commences
     immediately after the end of the prior Offering Period.

SECTION 4.  EMPLOYEE CONTRIBUTIONS.

     (a)  FREQUENCY OF PAYROLL DEDUCTIONS.  A Participant may purchase shares 
of Stock under the Plan solely by means of payroll deductions.  Payroll 
deductions, as designated by the Participant pursuant to Subsection (b) 
below, shall occur on each payday during participation in the Plan.

     (b)  AMOUNT OF PAYROLL DEDUCTIONS.  An Eligible Employee shall designate 
on the enrollment form the portion of his or her Compensation that he or she 
elects to have withheld for the purchase of Stock.  Such portion shall be a 
whole percentage of the Eligible Employee's Compensation, but not less than 
1% nor more than 10%.

     (c)  CHANGING WITHHOLDING RATE.  If a Participant wishes to change the 
rate of payroll withholding, he or she may do so by filing a new enrollment 
form with the Company at the prescribed location at any time.  The new 
withholding rate shall be effective as soon as 


                                       2

<PAGE>

reasonably practicable after such form has been received by the Company.  The 
new withholding rate shall be a whole percentage of the Eligible Employee's 
Compensation, but not less than 1% nor more than 10%.

     (d)  DISCONTINUING PAYROLL DEDUCTIONS.  If a Participant wishes to 
discontinue employee contributions entirely, he or she may do so by filing a 
new enrollment form with the Company at the prescribed location at any time.  
Payroll withholding shall cease as soon as reasonably practicable after such 
form has been received by the Company.  (In addition, employee contributions 
may be discontinued automatically pursuant to Section 8(b).)  A Participant 
who has discontinued employee contributions may resume such contributions by 
filing a new enrollment form with the Company at the prescribed location.  
Payroll withholding shall resume as soon as reasonably practicable after such 
form has been received by the Company.

     (e)  LIMIT ON NUMBER OF ELECTIONS.  No Participant shall make more than 
two elections under Subsection (c) or (d) above during any Accumulation 
Period.

SECTION 5.  WITHDRAWAL FROM THE PLAN.

     (a)  WITHDRAWAL.  A Participant may elect to withdraw from the Plan by 
filing the prescribed form with the Company at the prescribed location at any 
time before the last day of an Accumulation Period.  As soon as reasonably 
practicable thereafter, payroll deductions shall cease and the entire amount 
credited to the Participant's Plan Account shall be refunded to him or her in 
cash, without interest.  No partial withdrawals shall be permitted.

     (b)  RE-ENROLLMENT AFTER WITHDRAWAL.  A former Participant who has 
withdrawn from the Plan shall not be a Participant until he or she re-enrolls 
in the Plan under Section 3(c).  Re-enrollment may be effective only at the 
commencement of an Offering Period.

SECTION 6.  CHANGE IN EMPLOYMENT STATUS.

     (a)  TERMINATION OF EMPLOYMENT.  Termination of employment as an 
Eligible Employee for any reason, including death, shall be treated as an 
automatic withdrawal from the Plan under Section 5(a).  (A transfer from one 
Participating Company to another shall not be treated as a termination of 
employment.)

     (b)  LEAVE OF ABSENCE.  For purposes of the Plan, employment shall not 
be deemed to terminate when the Participant goes on a military leave, a sick 
leave or another BONA FIDE leave of absence, if the leave was approved by the 
Company in writing.  Employment, however, shall be deemed to terminate 90 days 
after the Participant goes on a leave, unless a contract or statute 
guarantees his or her right to return to work.  Employment shall be deemed to 
terminate in any event when the approved leave ends, unless the Participant 
immediately returns to work.

     (c)  DEATH.  In the event of the Participant's death, the amount credited 
to his or her Plan Account shall be paid to a beneficiary designated by him or 
her for this purpose on the 


                                       3

<PAGE>

prescribed form or, if none, to the Participant's estate.  Such form 
shall be valid only if it was filed with the Company at the prescribed 
location before the Participant's death.

SECTION 7.  PLAN ACCOUNTS AND PURCHASE OF SHARES.

     (a)  PLAN ACCOUNTS.  The Company shall maintain a Plan Account on its 
books in the name of each Participant.  Whenever an amount is deducted from 
the Participant's Compensation under the Plan, such amount shall be credited 
to the Participant's Plan Account.  Amounts credited to Plan Accounts shall 
not be trust funds and may be commingled with the Company's general assets 
and applied to general corporate purposes.  No interest shall be credited to 
Plan Accounts.

     (b)  PURCHASE PRICE.  The Purchase Price for each share of Stock 
purchased at the close of an Accumulation Period shall be the lower of:

           (i) 85% of the Fair Market Value of such share on the last trading 
     day in such Accumulation Period; or
     
          (ii) 85% of the Fair Market Value of such share on the last trading 
     day before the commencement of the applicable Offering Period (as 
     determined under Section 3(e)).
     
     (c)  NUMBER OF SHARES PURCHASED.  As of the last day of each 
Accumulation Period, each Participant shall be deemed to have elected to 
purchase the number of shares of Stock calculated in accordance with this 
Subsection (c), unless the Participant has previously elected to withdraw 
from the Plan in accordance with Section 5(a).  The amount then in the 
Participant's Plan Account shall be divided by the Purchase Price, and the 
number of shares that results shall be purchased from the Company with the 
funds in the Participant's Plan Account. The foregoing notwithstanding, no 
Participant shall purchase more than 1,000 shares of Stock with respect to 
any Accumulation Period nor more than the amounts of Stock set forth in 
Sections 8(b) and 13(a).  The Committee may determine with respect to all 
Participants that any fractional share, as calculated under this Subsection 
(c), shall be (i) rounded down to the next lower whole share or (ii) credited 
as a fractional share.

     (d)  AVAILABLE SHARES INSUFFICIENT.  In the event that the aggregate 
number of shares that all Participants elect to purchase during an 
Accumulation Period exceeds the maximum number of shares available for 
issuance under Section 13(a), then the number of shares to which each 
Participant is entitled shall be determined by multiplying the number of 
shares available for issuance by a fraction, the numerator of which is the 
number of shares that such Participant has elected to purchase and the 
denominator of which is the number of shares that all Participants have 
elected to purchase.

     (e)  ISSUANCE OF STOCK.  Certificates representing the shares of Stock 
purchased by a Participant under the Plan shall be issued to him or her as 
soon as reasonably practicable after the close of the applicable Accumulation 
Period, except that the Committee may determine that such 


                                       4

<PAGE>

shares shall be held for each Participant's benefit by a broker designated by 
the Committee (unless the Participant has elected that certificates be issued 
to him or her).  Shares may be registered in the name of the Participant or 
jointly in the name of the Participant and his or her spouse as joint tenants 
with right of survivorship or as community property.

     (f)  UNUSED CASH BALANCES.  An amount remaining in the Participant's 
Plan Account that represents the Purchase Price for any fractional share 
shall be carried over in the Participant's Plan Account to the next 
Accumulation Period. Any amount remaining in the Participant's Plan Account 
that represents the Purchase Price for whole shares that could not be 
purchased by reason of Subsection (c) above, Section 8(b) or Section 13(a) 
shall be refunded to the Participant in cash, without interest.

     (g)  STOCKHOLDER APPROVAL.  Any other provision of the Plan 
notwithstanding, no shares of Stock shall be purchased under the Plan unless 
and until the Company's stockholders have approved the adoption of the Plan.

SECTION 8.  LIMITATIONS ON STOCK OWNERSHIP.

     (a)  FIVE PERCENT LIMIT.  Any other provision of the Plan 
notwithstanding, no Participant shall be granted a right to purchase Stock 
under the Plan if such Participant, immediately after his or her election to 
purchase such Stock, would own stock possessing more than 5% of the total 
combined voting power or value of all classes of stock of the Company or any 
parent or Subsidiary of the Company.  For purposes of this Subsection (a), 
the following rules shall apply:

           (i) Ownership of stock shall be determined after applying the 
     attribution rules of section 424(d) of the Code;
     
          (ii) Each Participant shall be deemed to own any stock that he or 
     she has a right or option to purchase under this or any other plan; and
     
         (iii) Each Participant shall be deemed to have the right to purchase 
     1,000 shares of Stock under this Plan with respect to each Accumulation 
     Period.
     
     (b)  DOLLAR LIMIT.  Any other provision of the Plan notwithstanding, no
Participant shall purchase Stock with a Fair Market Value in excess of the
following limit:

           (i) In the case of Stock purchased during an Offering Period that 
     commenced in the current calendar year, the limit shall be equal to (A) 
     $25,000 minus (B) the Fair Market Value of the Stock that the 
     Participant previously purchased in the current calendar year (under 
     this Plan and all other employee stock purchase plans of the Company or 
     any parent or Subsidiary of the Company).
     
          (ii) In the case of Stock purchased during an Offering Period that 
     commenced in the immediately preceding calendar year, the limit shall be 
     equal to 


                                       4

<PAGE>

     (A) $50,000 minus (B) the Fair Market Value of the Stock that the 
     Participant previously purchased (under this Plan and all other employee 
     stock purchase plans of the Company or any parent or Subsidiary of the 
     Company) in the current calendar year and in the immediately preceding 
     calendar year.
     
         (iii) In the case of Stock purchased during an Offering Period that 
     commenced in the second preceding calendar year, the limit shall be 
     equal to (A) $75,000 minus (B) the Fair Market Value of the Stock that 
     the Participant previously purchased (under this Plan and all other 
     employee stock purchase plans of the Company or any parent or Subsidiary 
     of the Company) in the current calendar year and in the two preceding 
     calendar years.
     
For purposes of this Subsection (b), the Fair Market Value of Stock shall be 
determined in each case as of the beginning of the Offering Period in which 
such Stock is purchased.  Employee stock purchase plans not described in 
section 423 of the Code shall be disregarded.  If a Participant is precluded 
by this Subsection (b) from purchasing additional Stock under the Plan, then 
his or her employee contributions shall automatically be discontinued and 
shall resume at the beginning of the earliest Accumulation Period ending in 
the next calendar year (if he or she then is an Eligible Employee).

SECTION 9.  RIGHTS NOT TRANSFERABLE.

     The rights of any Participant under the Plan, or any Participant's 
interest in any Stock or moneys to which he or she may be entitled under the 
Plan, shall not be transferable by voluntary or involuntary assignment or by 
operation of law, or in any other manner other than by beneficiary 
designation or the laws of descent and distribution.  If a Participant in any 
manner attempts to transfer, assign or otherwise encumber his or her rights 
or interest under the Plan, other than by beneficiary designation or the laws 
of descent and distribution, then such act shall be treated as an election by 
the Participant to withdraw from the Plan under Section 5(a).

SECTION 10.  NO RIGHTS AS AN EMPLOYEE.

     Nothing in the Plan or in any right granted under the Plan shall confer 
upon the Participant any right to continue in the employ of a Participating 
Company for any period of specific duration or interfere with or otherwise 
restrict in any way the rights of the Participating Companies or of the 
Participant, which rights are hereby expressly reserved by each, to terminate 
his or her employment at any time and for any reason, with or without cause.

SECTION 11.  NO RIGHTS AS A STOCKHOLDER.

     A Participant shall have no rights as a stockholder with respect to any 
shares of Stock that he or she may have a right to purchase under the Plan 
until such shares have been purchased on the last day of the applicable 
Accumulation Period.

SECTION 12.  SECURITIES LAW REQUIREMENTS.

     Shares of Stock shall not be issued under the Plan unless the issuance 
and delivery of such shares comply with (or are exempt from) all applicable 
requirements of law, including (without limitation) the Securities Act of 
1933, as amended, the rules and regulations promulgated thereunder, state 
securities laws and regulations, and the regulations of any stock exchange or 
other securities market on which the Company's securities may then be traded.

SECTION 13.  STOCK OFFERED UNDER THE PLAN.

     (a)  AUTHORIZED SHARES.  The number of shares of Stock available to all 
Participants for purchase under the Plan with respect to any Accumulation 
Period shall be 50,000, subject to adjustment pursuant to this Section 13.  
If fewer than 50,000 shares of Stock are purchased during an Accumulation 
Period, the unused shares shall not be available during any subsequent 
Accumulation Period.  The aggregate number of shares of Stock available to 
all Participants for purchase during the life of the Plan shall be 100,000, 
subject to adjustment pursuant to this Section 13.

     (b)  ANTI-DILUTION ADJUSTMENTS.  The number of shares of Stock available 
to all Participants with respect to any Accumulation Period or during the 
life of the Plan, the 1,000-share limitation described in Section 7(c) and 
the price of shares that any Participant has elected to purchase shall be 
adjusted proportionately by the Committee for any increase or decrease in the 
number of outstanding shares of Stock resulting from a subdivision or 
consolidation of shares or the payment of a stock dividend, any other 
increase or decrease in such shares effected without receipt or payment of 
consideration by the Company, the distribution of the shares of a Subsidiary 
to the Company's stockholders or a similar event.

     (c)  REORGANIZATIONS.  Any other provision of the Plan notwithstanding, 
immediately prior to the effective time of a Corporate Reorganization, the 
Offering Period and Accumulation Period then in progress shall terminate and 
shares shall be purchased pursuant to Section 7, unless the Plan is assumed 
by the surviving corporation or its parent corporation pursuant to the plan 
of merger or consolidation.  The Plan shall in no event be construed to 
restrict in any way the Company's right to undertake a dissolution, 
liquidation, merger, consolidation or other reorganization.

SECTION 14.  AMENDMENT OR DISCONTINUANCE.

     The Board shall have the right to amend, suspend or terminate the Plan 
at any time and without notice.  Except as provided in Section 13, any 
increase in the aggregate number of shares of Stock to be issued under the 
Plan shall be subject to approval by a vote of the stockholders of the 
Company.  In addition, any other amendment of the Plan shall be subject to 
approval by a vote of the stockholders of the Company to the extent required 
by an applicable law or regulation.

                   (Amended and Restated as of June 3, 1998)
                                       
                                  ARTICLE ONE
                                    GENERAL
                                       
  I.  PURPOSE OF THE PLAN

      A.   This 1993 Stock Option/Stock Issuance Plan ("Plan") is intended to
promote the interests of Cornerstone Imaging, Inc., a Delaware corporation (the
"Corporation"), by providing eligible individuals with the opportunity to
acquire a proprietary interest, or otherwise increase their proprietary
interest, in the Corporation as an incentive for them to remain in the service
of the Corporation (or its parent or subsidiary corporations).

      B.   The Plan became effective on September 8, 1993, the first date on
which the shares of the Corporation's common stock were registered under
Section 12(g) of the Securities Exchange Act of 1934, as amended (the "1934
Act"). Such date is hereby designated as the IPO Effective Date.

      C.   This Plan serves as the successor to the Corporation's existing
Employee Stock Option Plan and Key Employee Stock Purchase Plan (the
"Predecessor Plans"), and no further option grants or share issuances shall be
made under the Predecessor Plans from and after the IPO Effective Date. All
outstanding stock options and unvested share issuances under the Predecessor
Plans on the IPO Effective Date are hereby incorporated into this Plan and
shall accordingly be treated as outstanding stock options and unvested share
issuances under this Plan. However, each outstanding option grant and unvested
share issuance so incorporated shall continue to be governed solely by the
express terms and conditions of the instrument evidencing such grant or
issuance, and no provision of this Plan shall be deemed to affect or otherwise
modify the rights or obligations of the holders of such incorporated options
with respect to their acquisition of shares of the Corporation's common stock
thereunder. All unvested shares of the Corporation's common stock outstanding
under the Predecessor Plans on the IPO Effective Date shall continue to be
governed solely by the express terms and conditions of the instruments
evidencing such issuances, and no provision of this Plan shall be deemed to
affect or modify the rights or obligations of the holders of such unvested
shares.

  II. DEFINITIONS

      For purposes of the Plan, the following definitions shall be in effect:

      BOARD:  the Corporation's Board of Directors.

      CODE:  the Internal Revenue Code of 1986, as amended.

      CHANGE IN CONTROL:  a change in ownership or control of the
Corporation effected through either of the following transactions:

          a.   the acquisition directly or indirectly by any person or related
     group of persons (other than the Corporation or a person that directly or
     indirectly controls, is controlled by, or is under common control with,
     the Corporation) of beneficial ownership (within the meaning of Rule 13d-3
     of the 1934 Act) of securities possessing more than fifty percent (50%) of
     the total combined voting power of the Corporation's outstanding
     securities pursuant to a tender or exchange offer made directly to the
     Corporation's stockholders which the Board does not recommend such
     stockholders to accept; or
     
          b.   a change in the composition of the Board over a period of
     thirty-six (36) consecutive months or less such that a majority of the
     Board members (rounded up to the next whole number) ceases, by reason of
     one or more proxy contests for the election of Board members, to be
     comprised of individuals who either (A) have been Board members
     continuously since the beginning of such period or (B) have been elected
     or nominated for election as Board members during such period by at least
     a majority of the Board members described in clause (A) who were still in
     office at the time such election or nomination was approved by the Board.
     
      CORPORATE TRANSACTION:  any of the following stockholder-approved
transactions to which the Corporation is a party:

          a.   a merger or consolidation in which the Corporation is not the
     surviving entity, except for a transaction the principal purpose of which
     is to change the state in which the Corporation is incorporated,
     
          b.   the sale, transfer or other disposition of all or substantially
     all of the assets of the Corporation in complete liquidation or
     dissolution of the Corporation, or
     
          c.   any reverse merger in which the Corporation is the surviving
     entity but in which securities possessing more than fifty percent (50%) of
     the total combined voting power of the Corporation's outstanding
     securities are transferred to a person or persons different from those who
     held such securities immediately prior to such merger.
     
      EMPLOYEE:  an individual who performs services while in the employ of
the Corporation or one or more parent or subsidiary corporations, subject to
the control and direction of the employer entity not only as to the work to be
performed but also as to the manner and method of performance.

      FAIR MARKET VALUE:  the Fair Market Value per share of Common Stock
determined in accordance with the following provisions:

          a.   If the Common Stock is not at the time listed or admitted to
     trading on any national stock exchange but is traded on the Nasdaq
     National Market, the Fair Market Value shall be the closing price per
     share on the date in question, as such price is 

                                       2

<PAGE>

     reported on the Nasdaq National Market or any successor system. If there 
     is no reported closing price for the Common Stock on the date in question,
     then the closing price on the last preceding date for which such quotation
     exists shall be determinative of Fair Market Value.
     
          b.   If the Common Stock is at the time listed or admitted to trading
     on any national stock exchange, then the Fair Market Value shall be the
     closing selling price per share on the date in question on the exchange
     determined by the Plan Administrator to be the primary market for the
     Common Stock, as such price is officially quoted in the composite tape of
     transactions on such exchange. If there is no reported sale of Common
     Stock on such exchange on the date in question, then the Fair Market Value
     shall be the closing selling price on the exchange on the last preceding
     date for which such quotation exists.
     
      HOSTILE TAKE-OVER:  a change in ownership of the Corporation effected
through the following transaction:

          a.   any person or related group of persons (other than the
     Corporation or a person that directly or indirectly controls, is
     controlled by, or is under common control with, the Corporation) directly
     or indirectly acquires beneficial ownership (within the meaning of Rule
     13d-3 of the 1934 Act) of securities possessing more than fifty percent
     (50%) of the total combined voting power of the Corporation's outstanding
     securities pursuant to a tender or exchange offer made directly to the
     Corporation's stockholders which the Board does not recommend such
     stockholders to accept, AND
     
          b.   more than fifty percent (50%) of the securities so acquired in
     such tender or exchange offer are accepted from holders other than the
     officers and directors of the Corporation subject to the short-swing
     profit restrictions of Section 16 of the 1934 Act.
     
      OPTIONEE:  a person to whom an option is granted under the 
Discretionary Option Grant Program or the Automatic Option Grant Program.

      PARTICIPANT:  a person who is issued Common Stock under the Stock 
Issuance Program.

      PERMANENT DISABILITY OR PERMANENTLY DISABLED:  the inability of the
Optionee or the Participant to engage in any substantial gainful activity by
reason of any medically determinable physical or mental impairment expected to
result in death or to be of continuous duration of twelve (12) months or more.

      SERVICE:  the performance of services on a periodic basis to the
Corporation (or any parent or subsidiary corporation) in the capacity of an
Employee, a non-employee member of the Board or an independent consultant or
advisor, except to the extent otherwise specifically provided in the applicable

      TAKE-OVER PRICE:  the GREATER of (a) the Fair Market Value per share
of Common Stock on the date the option is surrendered to the Corporation in
connection with a Hostile Take-Over or (b) the highest reported price per share
of Common Stock paid by the tender offeror in effecting such Hostile Take-Over.
However, if the surrendered option is an Incentive Option, the Take-Over Price
shall not exceed the clause (a) price per share.

         B.  The following provisions shall be applicable in determining the
parent and subsidiary corporations of the Corporation:

             Any corporation (other than the Corporation) in an unbroken chain
    of corporations ending with the Corporation shall be considered to be a 
    PARENT of the Corporation, provided each such corporation in the unbroken 
    chain (other than the Corporation) owns, at the time of the 
    determination, stock possessing fifty percent (50%) or more of the total 
    combined voting power of all classes of stock in one of the other 
    corporations in such chain.

             Each corporation (other than the Corporation) in an unbroken chain
    of corporations beginning with the Corporation shall be considered to be 
    a SUBSIDIARY of the Corporation, provided each such corporation (other 
    than the last corporation) in the unbroken chain owns, at the time of the 
    determination, stock possessing fifty percent (50%) or more of the total 
    combined voting power of all classes of stock in one of the other 
    corporations in such chain.

    III. STRUCTURE OF THE PLAN

         A.  STOCK PROGRAMS.  The Plan shall be divided into three (3) separate
components: the Discretionary Option Grant Program specified in Article Two,
the Automatic Option Grant Program specified in Article Three and the Stock
Issuance Program specified in Article Four. Under the Discretionary Option
Grant Program, eligible individuals may, at the discretion of the Plan
Administrator, be granted options to purchase shares of Common Stock in
accordance with the provisions of Article Two. Under the Automatic Option Grant
Program, (i) each individual who first joins the Board as a non-employee
director on or after November 5, 1993 will receive an option grant at that time
and (ii) each non-employee director will receive an annual option grant to
purchase shares of Common Stock, both in accordance with the provisions of
Article Three. Under the Stock Issuance Program, eligible individuals may be
issued shares of Common Stock directly, either through the immediate purchase
of such shares at a price not less than eighty-five percent (85%) of the Fair
Market Value of the shares at the time of issuance or as a bonus tied to the
performance of services or the Corporation's attainment of financial
objectives, without any cash payment required of the recipient.

         B.  GENERAL PROVISIONS.  Unless the context clearly indicates 
otherwise, the provisions of Articles One and Five shall apply to the 
Discretionary Option Grant Program, the Automatic Option Grant Program and 
the Stock Issuance Program and shall accordingly govern the interests of all 
individuals under the Plan.

    IV.  ADMINISTRATION OF THE PLAN

                                       4

<PAGE>

         The Plan shall be administered in accordance with the following 
standards:

         A.  The Board shall appoint a committee consisting of not less than 
two (2) non-employee Board members to administer the Discretionary Option 
Grant and Stock Issuance Programs of the Plan, including (without limitation) 
the power to grant options under the Discretionary Option Grant Program and 
approve stock issuances under the Stock Issuance Program, the power to 
accelerate the exercisability of options granted under the Discretionary 
Option Grant Program and the vesting of shares issued under the Stock 
Issuance Program and the power to administer the option surrender provisions 
of the Discretionary Option Grant Program. This committee shall function as 
the "Primary Committee" under the Plan and shall have sole and exclusive 
authority to grant stock options to officers of the Corporation who are Board 
members. No non-employee Board member shall be eligible to serve on the 
Primary Committee if such individual has, within the relevant period 
designated below, received an option grant or direct stock issuance under 
this Plan or any other stock plan of the Corporation (or any parent or 
subsidiary corporation) other than pursuant to the Automatic Option Grant 
Program:

             (1)  for each of the initial members of the Primary Committee, 
the period commencing with the IPO Effective Date and ending with the date of 
his or her appointment to the Primary Committee, or

             (2)  for any successor or substitute member, the twelve 
(12)-month period immediately preceding the date of his or her appointment to 
the Primary Committee or (if shorter) the period commencing with the IPO 
Effective Date and ending with the date of his or her appointment to the 
Primary Committee.

         B.  Administration of the Discretionary Option Grant and Stock 
Issuance Programs with respect to the officers of the Corporation who are not 
Board members and all other key employees eligible to participate in the Plan 
may, at the Board's discretion, be vested in the Primary Committee or in a 
secondary committee of two (2) or more Board members appointed by the Board, 
or the Board may retain the power to administer the Plan with respect to all 
individuals who are not Board members. Should a secondary committee be 
appointed, the membership may include Board members who are employees of the 
Corporation eligible to receive option grants or stock issuances under this 
Plan or under any other stock option, stock appreciation, stock bonus or 
other stock plan of the Corporation (or any parent or subsidiary corporation).

         C.  Members of the Primary Committee or any secondary committee 
shall serve for such term as the Board may determine and shall be subject to 
removal by the Board at any time.

         D.  The term "Plan Administrator" as used from time to time in this 
plan document shall mean the particular entity, whether the Primary Committee 
or any secondary committee, which is authorized to administer the 
Discretionary Option Grant and Stock Issuance Programs with respect to one or 
more classes of eligible individuals, to the extent such entity is carrying 
out its administrative functions under the Plan with respect to those 
individuals.

                                       5

<PAGE>

         E.  The Plan Administrator shall have full power and authority 
(subject to the express provisions of the Plan) to establish rules and 
regulations for the proper administration of the Discretionary Option Grant 
and Stock Issuance Programs and to make such determinations under, and issue 
such interpretations of, the provisions of such programs and any outstanding 
option grants or stock issuances thereunder as it may deem necessary or 
advisable. Decisions of the Plan Administrator shall be final and binding on 
all parties who have an interest in the Discretionary Option Grant or Stock 
Issuance Programs or any outstanding option or share issuance thereunder.

         F.  Administration of the Automatic Option Grant Program shall be 
self-executing in accordance with the express terms and conditions of Article 
Three, and the Plan Administrator shall exercise no discretionary functions 
with respect to option grants made pursuant to that program.

    V.   ELIGIBILITY FOR OPTION GRANTS AND STOCK ISSUANCES

         A.  The persons eligible to participate in the Discretionary Option 
Grant Program under Article Two or the Stock Issuance Program under Article 
Four shall be limited to the following:

             (i)  officers and other key employees of the Corporation (or its
     parent or subsidiary corporations) who render services which contribute to
     the management, growth and financial success of the Corporation (or its
     parent or subsidiary corporations); and
     
             (ii) those consultants or other independent contractors who 
     provide valuable services to the Corporation (or its parent or subsidiary
     corporations).
     
         B.  The non-employee members of the Board, other than members of the 
Primary Committee, shall be eligible to participate in the Discretionary 
Option Grant and Stock Issuance Programs. No member of the Primary Committee 
shall be eligible to participate in the Discretionary Option Grant or Stock 
Issuance Program or in any other stock option, stock purchase, stock bonus or 
other stock plan of the Corporation (or its parent or subsidiary 
corporations). Non-employee members of the Board, including members of the 
Primary Committee, shall be eligible to receive automatic option grants 
pursuant to the provisions of Article Three.

         C.  The Plan Administrator shall have full authority, within the 
scope of its administrative functions under the Plan, to determine, (I) with 
respect to the option grants made under the Discretionary Option Grant 
Program, which eligible individuals are to receive option grants, the number 
of shares to be covered by each such grant, the status of the granted option 
as either an incentive stock option ("Incentive Option") which satisfies the 
requirements of Section 422 of the Code or a non-statutory option not 
intended to meet such requirements, the time or times at which each granted 
option is to become exercisable and the maximum term for which the option may 
remain outstanding and (II), with respect to stock issuances under the Stock 
Issuance Program, the number of shares to be issued to each Participant, the 
vesting schedule (if 

                                       6

<PAGE>

any) to be applicable to the issued shares, and the consideration to be paid 
by the individual for such shares.

    VI.  STOCK SUBJECT TO THE PLAN

         A.  Shares of Common Stock shall be available for issuance under the 
Plan and shall be drawn from either the Corporation's authorized but unissued 
shares of Common Stock or from reacquired shares of Common Stock, including 
shares repurchased by the Corporation on the open market. The maximum number 
of shares of Common Stock which may be issued over the term of the Plan shall 
not exceed 2,674,852(1) shares, subject to adjustment from time to time in 
accordance with the provisions of this Section VI. In no event may any one 
individual participating in the Plan acquire shares of Common Stock under the 
Plan in excess of 500,000 shares of Common Stock in the aggregate over the 
term of the Plan. For purposes of this limitation, any option grants or stock 
awards made prior to January 1, 1996 will not be taken into account.

         B.  Should one or more outstanding options under this Plan 
(including outstanding options under the Predecessor Plans incorporated into 
this Plan) expire or terminate for any reason prior to exercise in full 
(including any option cancelled in accordance with the cancellation-regrant 
provisions of Section IV of Article Two of the Plan), then the shares subject 
to the portion of each option not so exercised shall be available for 
subsequent option grants under the Plan. Shares subject to any option or 
portion thereof surrendered or cancelled in accordance with Section V of 
Article Two and all share issuances under the Plan (including unvested share 
issuances under the Predecessor Plans which have been incorporated into this 
Plan), whether or not the shares are subsequently repurchased by the 
Corporation pursuant to its repurchase rights under the Plan, shall reduce on 
a share-for-share basis the number of shares of Common Stock available for 
subsequent option grants under the Plan. In addition, should the option price 
of an outstanding option under the Plan (including any option incorporated 
from the Predecessor Plans) be paid with shares of Common Stock or should 
shares of Common Stock otherwise issuable under the Plan be withheld by the 
Corporation in satisfaction of the withholding taxes incurred in connection 
with the exercise of an outstanding option under the Plan or the vesting of a 
direct share issuance made under the Plan, then the number of shares of 
Common Stock available for issuance under the Plan shall be reduced by the 
gross number of shares for which the option is exercised or which vest under 
the share issuance, and not by the net number of shares of Common Stock 
actually issued to the holder of such option or share issuance.

         C.  Should any change be made to the Common Stock issuable under the 
Plan by reason of any stock split, stock dividend, recapitalization, 
combination of shares, exchange of shares or other change affecting the 
outstanding Common Stock as a class without the

January 30, 1996, and approved by the stockholders at the 1996 Annual 
Stockholders' Meeting, (ii) the 400,000-share increase authorized by the 
Board on February 14, 1997, and approved by the stockholders at the 1997 
Annual Stockholders' Meeting and (iii) the 200,000-share increase authorized 
by the Board on March 25, 1998, and approved by the stockholders at the 1998 
Annual Stockholders' Meeting.

Corporation's receipt of consideration, then appropriate adjustments shall be 
made to (i) the maximum number and/or class of securities issuable under the 
Plan, (ii) the number and/or class of securities for which automatic option 
grants are to be subsequently made per eligible non-employee Board member 
under the Automatic Option Grant Program, (iii) the number and/or class of 
securities and price per share in effect under each outstanding option and 
(iv) the number and/or class of securities and price per share in effect 
under each outstanding option incorporated into this Plan from the 
Predecessor Plans. Such adjustments to the outstanding options are to be 
effected in a manner which shall preclude the enlargement or dilution of 
rights and benefits under such options. The adjustments determined by the 
Primary Committee shall be final, binding and conclusive.

                      DISCRETIONARY OPTION GRANT PROGRAM
                                       
       I.    TERMS AND CONDITIONS OF OPTIONS

             Options granted pursuant to the Discretionary Option Grant 
Program shall be authorized by action of the Plan Administrator and may, at 
the Plan Administrator's discretion, be either Incentive Options or 
non-statutory options. Individuals who are not Employees of the Corporation 
or its parent or subsidiary corporations may only be granted non-statutory 
options. Each granted option shall be evidenced by one or more instruments in 
the form approved by the Plan Administrator; PROVIDED, however, that each 
such instrument shall comply with the terms and conditions specified below. 
Each instrument evidencing an Incentive Option shall, in addition, be subject 
to the applicable provisions of Section II of this Article Two.

             A.       OPTION PRICE.

                 (1)  The option price per share shall be fixed by the Plan 
Administrator in accordance with the following provisions:

                            (i)    The option price per share of the Common 
Stock subject to an Incentive Option shall in no event be less than one 
hundred percent (100%) of the Fair Market Value of such Common Stock on the 
grant date.

                            (ii)   The option price per share of the Common 
Stock subject to a non-statutory stock option shall in no event be less than 
eighty-five percent (85%) of the Fair Market Value of such Common Stock on 
the grant date.

                 (2)  The option price shall become immediately due upon 
exercise of the option and, subject to the provisions of Section I of Article 
Five and the instrument evidencing the grant, shall be payable in one of the 
following alternative forms specified below:

                      -    full payment in cash or check drawn to the
Corporation's order;

                      -    full payment in shares of Common Stock held for 
the requisite period necessary to avoid a charge to the Corporation's 
earnings for financial reporting purposes and valued at Fair Market Value on 
the Exercise Date (as such term is defined below);

                      -    full payment in a combination of shares of Common 
Stock held for the requisite period necessary to avoid a charge to the 
Corporation's earnings for financial reporting purposes and valued at Fair 
Market Value on the Exercise Date and cash or check drawn to the 
Corporation's order; or

                      -    full payment through a broker-dealer sale and 
remittance procedure pursuant to which the Optionee shall provide irrevocable 
written instructions to (I) a Corporation-designated brokerage firm to effect 
the immediate sale of the purchased shares and 

                                       9
<PAGE>

remit to the Corporation, out of the sale proceeds available on the 
settlement date, sufficient funds to cover the aggregate option price payable 
for the purchased shares plus all applicable Federal and state income and 
employment taxes required to be withheld by the Corporation in connection 
with such purchase and (II) to the Corporation to deliver the certificates 
for the purchased shares directly to such brokerage firm in order to complete 
the sale transaction.

             For purposes of this subparagraph (2), the Exercise Date shall 
be the date on which written notice of the option exercise is delivered to 
the Corporation. Except to the extent the sale and remittance procedure is 
used in connection with the exercise of the option, payment of the option 
price for the purchased shares must accompany such notice.

             B.  TERM AND EXERCISE OF OPTIONS. Each option granted under this 
Discretionary Option Grant Program shall be exercisable at such time or times 
and during such period as is determined by the Plan Administrator and set 
forth in the instrument evidencing the grant. No such option, however, shall 
have a maximum term in excess of ten (10) years from the grant date. During 
the lifetime of the Optionee, the option, together with any stock 
appreciation rights pertaining to such option, shall be exercisable only by 
the Optionee and shall not be assignable or transferable by the Optionee 
except for a transfer of the option effected by will or by the laws of 
descent and distribution following the Optionee's death.

             C.  TERMINATION OF SERVICE.

                 (1)  The following provisions shall govern the exercise period
applicable to any outstanding options held by the Optionee at the time of
cessation of Service or death.

                  -    Should an Optionee cease Service for any reason 
(including death or Permanent Disability) while holding one or more 
outstanding options under this Article Two, then none of those options shall 
(except to the extent otherwise provided pursuant to subparagraph C(3) below) 
remain exercisable for more than a thirty-six (36)-month period (or such 
shorter period determined by the Plan Administrator and set forth in the 
instrument evidencing the grant) measured from the date of such cessation of 
Service.

                  -    Any option held by the Optionee under this Article Two 
and exercisable in whole or in part on the date of his or her death may be 
subsequently exercised by the personal representative of the Optionee's 
estate or by the person or persons to whom the option is transferred pursuant 
to the Optionee's will or in accordance with the laws of descent and 
distribution. Such exercise, however, must occur prior to the EARLIER of (i) 
the first anniversary of the date of the Optionee's death or (ii) the 
specified expiration date of the option term. Upon the occurrence of the 
earlier event, the option shall terminate.

                  -    Under no circumstances shall any such option be 
exercisable after the specified expiration date of the option term.

                  -    During the applicable post-Service exercise period, 
the option may not be exercised in the aggregate for more than the number of 
shares (if any) in which the

                                       10
<PAGE>

Optionee is vested at the time of his or her cessation of Service. Upon the 
expiration of the limited post-Service exercise period or (if earlier) upon 
the specified expiration date of the option term, each such option shall 
terminate and cease to be outstanding with respect to any vested shares for 
which the option has not otherwise been exercised. However, each outstanding 
option shall immediately terminate and cease to be outstanding, at the time 
of the Optionee's cessation of Service, with respect to any shares for which 
the option is not otherwise at that time exercisable or in which the Optionee 
is not otherwise vested.

                  -    Should (i) the Optionee's Service be terminated for 
misconduct (including, but not limited to, any act of dishonesty, willful 
misconduct, fraud or embezzlement) or (ii) the Optionee make any unauthorized 
use or disclosure of confidential information or trade secrets of the 
Corporation or its parent or subsidiary corporations, then in any such event 
all outstanding options held by the Optionee under this Article Two shall 
terminate immediately and cease to be outstanding.

                 (2)  The Plan Administrator shall have complete discretion, 
exercisable either at the time the option is granted or at any time while the 
option remains outstanding, to permit one or more options held by the 
Optionee under this Article Two to be exercised, during the limited 
post-Service exercise period applicable under subparagraph (1) above, not 
only with respect to the number of vested shares of Common Stock for which 
each such option is exercisable at the time of the Optionee's cessation of 
Service but also with respect to one or more subsequent installments of 
vested shares for which the option would otherwise have become exercisable 
had such cessation of Service not occurred.

                 (3)  The Plan Administrator shall also have full power and 
authority to extend the period of time for which the option is to remain 
exercisable following the Optionee's cessation of Service (or death or 
Permanent Disability) from the limited period in effect under subparagraph 
(1) above to such greater period of time as the Plan Administrator shall deem 
appropriate. In no event, however, shall such option be exercisable after the 
specified expiration date of the option term.

             D.  STOCKHOLDER RIGHTS. An Optionee shall have no stockholder 
rights with respect to any shares covered by the option until such individual 
shall have exercised the option and paid the option price for the purchased 
shares.

             E.  REPURCHASE RIGHTS.

             The shares of Common Stock acquired upon the exercise of any 
Article Two option grant may be subject to repurchase by the Corporation in 
accordance with the following provisions:

                 (a) The Plan Administrator shall have the discretion to 
       authorize the issuance of unvested shares of Common Stock under this 
       Article Two. Should the Optionee cease Service while holding such 
       unvested shares, the Corporation shall have the right to repurchase 
       any or all of those unvested shares at the option price paid per 
       share. The terms and conditions upon which such repurchase right shall 
       be exercisable

                                       11
<PAGE>

       (including the period and procedure for exercise and the appropriate 
       vesting schedule for the purchased shares) shall be established by the 
       Plan Administrator and set forth in the instrument evidencing such 
       repurchase right.

                 (b) All of the Corporation's outstanding repurchase rights 
       under this Article Two shall automatically terminate, and all shares 
       subject to such terminated rights shall immediately vest in full, upon 
       the occurrence of a Corporate Transaction.

                 (c) The Plan Administrator shall have the discretionary 
       authority, exercisable either before or after the Optionee's cessation 
       of Service, to cancel the Corporation's outstanding repurchase rights 
       with respect to one or more shares purchased or purchasable by the 
       Optionee under this Discretionary Option Grant Program and thereby 
       accelerate the vesting of such shares in whole or in part at any time.

       II.   INCENTIVE OPTIONS

             The terms and conditions specified below shall be applicable to 
all Incentive Options granted under this Article Two. Incentive Options may 
only be granted to individuals who are Employees of the Corporation. Options 
which are specifically designated as non-statutory options when issued under 
the Plan shall NOT be subject to such terms and conditions.

             A.   DOLLAR LIMITATION. The aggregate Fair Market Value 
(determined as of the respective date or dates of grant) of the Common Stock 
for which one or more options granted to any Employee under this Plan (or any 
other option plan of the Corporation or its parent or subsidiary 
corporations) may for the first time become exercisable as incentive stock 
options under the Federal tax laws during any one calendar year shall not 
exceed the sum of One Hundred Thousand Dollars ($100,000). To the extent the 
Employee holds two (2) or more such options which become exercisable for the 
first time in the same calendar year, the foregoing limitation on the 
exercisability of such options as incentive stock options under the Federal 
tax laws shall be applied on the basis of the order in which such options are 
granted. Should the number of shares of Common Stock for which any Incentive 
Option first becomes exercisable in any calendar year exceed the applicable 
One Hundred Thousand Dollar ($100,000) limitation, then that option may 
nevertheless be exercised in that calendar year for the excess number of 
shares as a non-statutory option under the Federal tax laws.

             B.  10% STOCKHOLDER. If any individual to whom an Incentive 
Option is granted is the owner of stock (as determined under Section 424(d) 
of the Code) possessing more than ten percent (10%) of the total combined 
voting power of all classes of stock of the Corporation or any one of its 
parent or subsidiary corporations, then the option price per share shall not 
be less than one hundred and ten percent (110%) of the Fair Market Value per 
share of Common Stock on the grant date, and the option term shall not exceed 
five (5) years measured from the grant date.

            Except as modified by the preceding provisions of this Section 
II, the provisions of Articles One, Two and Five of the Plan shall apply to 
all Incentive Options granted hereunder.

    III.    CORPORATE TRANSACTION/CHANGE IN CONTROL

            A.   In the event of any Corporate Transaction or Change in 
Control, each option which is at the time outstanding under this Article Two 
shall automatically accelerate so that each such option shall, immediately 
prior to the specified effective date for the Corporate Transaction or Change 
in Control, respectively, become fully exercisable with respect to the total 
number of shares of Common Stock at the time subject to such option and may 
be exercised for all or any portion of such shares.

            B.   Upon the consummation of the Corporate Transaction, all 
outstanding options under this Article Two shall terminate and cease to be 
outstanding, except to the extent assumed by the successor corporation or its 
parent company. Any options accelerated in connection with the Change in 
Control shall remain fully exercisable until the expiration or sooner 
termination of the option term.

            C.   Each outstanding option under this Article Two which is 
assumed in connection with the Corporate Transaction or is otherwise to 
continue in effect shall be appropriately adjusted, immediately after such 
Corporate Transaction, to apply and pertain to the number and class of 
securities which would have been issued to the option holder, in consummation 
of such Corporate Transaction, had such person exercised the option 
immediately prior to such Corporate Transaction. Appropriate adjustments 
shall also be made to the option price payable per share, PROVIDED the 
aggregate option price payable for such securities shall remain the same. In 
addition, the class and number of securities available for issuance under the 
Plan following the consummation of the Corporate Transaction shall be 
appropriately adjusted.

            D.   The grant of options under this Article Two shall in no way 
affect the right of the Corporation to adjust, reclassify, reorganize or 
otherwise change its capital or business structure or to merge, consolidate, 
dissolve, liquidate or sell or transfer all or any part of its business or 
assets.

            E.    The exercisability as incentive stock options under the 
Federal tax laws of any options accelerated under this Section III in 
connection with a Corporate Transaction or Change in Control shall remain 
subject to the dollar limitation of Section II of this Article Two. To the 
extent such dollar limitation is exceeded, the accelerated option shall be 
exercisable as a non-statutory option under the Federal tax laws.

      IV.   CANCELLATION AND REGRANT OF OPTIONS

            The Plan Administrator shall have the authority to effect, at any 
time and from time to time, with the consent of the affected optionees, the 
cancellation of any or all outstanding options under this Article Two 
(including outstanding options under the Predecessor Plans incorporated into 
this Plan) and to grant in substitution new options under the Plan covering 
the same or different numbers of shares of Common Stock but with an option 
price per share not less than (i) eighty-five percent (85%) of the Fair 
Market Value of the Common Stock on the new grant date or (ii) one hundred 
percent (100%) of such Fair Market Value in the case of an

                                       13
<PAGE>

Incentive Option or (iii) one hundred and ten percent (110%) of such Fair 
Market Value in the case of an Incentive Option granted to a 10% Stockholder.

      V.    STOCK APPRECIATION RIGHTS

            A.    Provided and only if the Primary Committee determines in its 
discretion to implement the stock appreciation right provisions of this 
Section V, one or more Optionees may be granted the right, exercisable upon 
such terms and conditions as the Primary Committee may establish, to 
surrender all or part of an unexercised option under this Article Two in 
exchange for a distribution from the Corporation in an amount equal to the 
excess of (i) the Fair Market Value (on the option surrender date) of the 
number of shares in which the Optionee is at the time vested under the 
surrendered option (or surrendered portion thereof) over (ii) the aggregate 
option price payable for such vested shares.

             B.   No surrender of an option shall be effective hereunder 
unless it is approved by the Primary Committee. If the surrender is so 
approved, then the distribution to which the Optionee shall accordingly 
become entitled under this Section V may be made in shares of Common Stock 
valued at Fair Market Value on the option surrender date, in cash, or partly 
in shares and partly in cash, as the Primary Committee shall in its sole 
discretion deem appropriate.

             C.   If the surrender of an option is rejected by the Primary 
Committee, then the Optionee shall retain whatever rights the Optionee had 
under the surrendered option (or surrendered portion thereof) on the option 
surrender date and may exercise such rights at any time prior to the LATER of 
(i) five (5) business days after the receipt of the rejection notice or (ii) 
the last day on which the option is otherwise exercisable in accordance with 
the terms of the instrument evidencing such option, but in no event may such 
rights be exercised more than ten (10) years after the date of the option 
grant.

             D.   One or more officers of the Corporation subject to the 
short-swing profit restrictions of the Federal securities laws may, in the 
Primary Committee's sole discretion, be granted limited stock appreciation 
rights in tandem with their outstanding options under the Plan. Upon the 
occurrence of a Hostile Take-Over effected at any time when the Corporation's 
outstanding Common Stock is registered under Section 12(g) of the 1934 Act, 
the officer shall have a thirty (30)-day period in which he or she may 
surrender any outstanding options with such a limited stock appreciation 
right in effect for at least six (6) months to the Corporation, to the extent 
such option is at the time exercisable for fully-vested shares of Common 
Stock. The officer shall in return be entitled to a cash distribution from 
the Corporation in an amount equal to the excess of (i) the Take-Over Price 
of the vested shares of Common Stock at the time subject to each surrendered 
option (or surrendered portion of such option) over (ii) the aggregate option 
price payable for such shares. The cash distribution payable upon such option 
surrender shall be made within five (5) days following the consummation of 
the Hostile Take-Over. Neither the approval of the Primary Committee nor the 
consent of the Board shall be required in connection with such option 
surrender and cash distribution. Any unsurrendered portion of the option shall

                                       14
<PAGE>

continue to remain outstanding and become exercisable in accordance 
with the terms of the instrument evidencing such grant.

             E.   The shares of Common Stock subject to any option 
surrendered for an appreciation distribution pursuant to this Section V shall 
NOT be available for subsequent option grant under the Plan.

                        AUTOMATIC OPTION GRANT PROGRAM
                                       
     I.   ELIGIBILITY

          The individuals eligible to receive automatic option grants pursuant
to the provisions of this Article Three shall be limited to the individuals who
are first elected or appointed as non-employee Board members on or after
November 5, 1993, whether through appointment by the Board or election by the
Corporation's stockholders, and each individual who serves as a non-employee
Board member thereafter. In no event, however, shall a non-employee Board
member be eligible to participate in the Automatic Option Grant Program if such
individual has at any time been in the prior employ of the Corporation (or any
parent or subsidiary corporation). Each non-employee Board member eligible to
participate in the Automatic Option Grant Program pursuant to the foregoing
criteria shall be designated an Eligible Director for purposes of the Plan.

    II.   TERMS AND CONDITIONS OF AUTOMATIC OPTION GRANTS

          A. GRANT DATES. Option grants will be made under this Article Three 
on the dates specified below:

             (i) Each Eligible Director who first becomes a non-employee Board
     member at any time after November 5, 1993, whether through election at an
     Annual Stockholders' Meeting or through appointment by the Board, shall
     automatically be granted, at the time of such initial election or
     appointment, a non-statutory stock option to purchase 10,000 shares of
     Common Stock upon the terms and conditions of this Article Three.
     
            (ii) Each Eligible Director who is serving as a nonemployee Board
     member on November 5, 1993 shall automatically be granted, on such date, a
     non-statutory stock option to purchase 10,000 shares of Common Stock upon
     the terms and conditions of this Article Three.
     
           (iii) On the date of each Annual Stockholders' Meeting, beginning 
     with the 1995 Annual Stockholders' Meeting, each Eligible Director who 
     is at the time serving as a non-employee member of the Board shall 
     automatically be granted at that meeting, whether or not such 
     individual is standing for re-election as a Board Member at that 
     particular meeting, a non-statutory stock option under the Plan to 
     purchase 2,500 shares of Common Stock, provided such individual has 
     served as a non-employee Board member for at least six (6) months prior 
     to the date of such meeting.
     
   The 10,000-share limitation on the initial automatic option grants and the 
2,500-share limitation on the subsequent automatic option grants to be made 
to each Eligible Director shall be subject to periodic adjustment pursuant to 
the applicable provisions of paragraph VI.C of Article One.


                                      16

       B. OPTION PRICE. The option price per share of Common Stock subject to
each automatic option grant made under this Article Three shall be equal to one
hundred percent (100%) of the Fair Market Value per share of Common Stock on
the automatic grant date.

       C. PAYMENT.

   The option price shall be payable in one of the alternative forms 
specified below:

          (i) full payment in cash or check drawn to the Corporation's order;
     
         (ii) full payment in shares of Common Stock held for the requisite
     period necessary to avoid a charge to the Corporation's earnings for
     financial reporting purposes and valued at Fair Market Value on the
     Exercise Date (as such term is defined below);
     
        (iii) full payment in a combination of shares of Common Stock held for
     the requisite period necessary to avoid a charge to the Corporation's
     earnings for financial reporting purposes and valued at Fair Market Value
     on the Exercise Date and cash or check drawn to the Corporation's order;
     or
     
         (iv) full payment through a broker-dealer sale and remittance
     procedure pursuant to which the Optionee shall provide irrevocable written
     instructions to (I) a Corporation-designated brokerage firm to effect the
     immediate sale of the purchased shares and remit to the Corporation, out
     of the sale proceeds available on the settlement date, sufficient funds to
     cover the aggregate option price payable for the purchased shares plus all
     applicable Federal and state income and employment taxes required to be
     withheld by the Corporation in connection with such purchase and (II) to
     the Corporation to deliver the certificates for the purchased shares
     directly to such brokerage firm in order to complete the sale transaction.
     
   For purposes of this subparagraph C, the Exercise Date shall be the date 
on which written notice of the option exercise is delivered to the 
Corporation. Except to the extent the sale and remittance procedure specified 
above is used for the exercise of the option, payment of the option price for 
the purchased shares must accompany the exercise notice.

       D. OPTION TERM. Each automatic grant under this Article Three shall have
a maximum term of ten (10) years measured from the automatic grant date.

       E. EXERCISABILITY. Each 10,000-share initial automatic grant shall
become exercisable in a series of four (4) equal and successive annual
installments over the Optionee's period of service on the Board, with the first
such installment to become exercisable one year after the automatic grant date.
Each 2,500-share subsequent automatic grant shall become exercisable in full on
the fourth (4th) anniversary of the automatic grant date, provided the Optionee
remains in service on the Board. The exercisability of each automatic grant
outstanding

                                      17

<PAGE>

under this Article Three shall be accelerated as provided in
Section II.G and Section III of this Article Three.

       F. NON-TRANSFERABILITY. During the lifetime of the Optionee, each
automatic option grant, together with the limited stock appreciation right
pertaining to such option, shall be exercisable only by the Optionee and shall
not be assignable or transferable by the Optionee other than a transfer of the
option effected by will or by the laws of descent and distribution following
Optionee's death.

       G. EFFECT OF TERMINATION OF BOARD MEMBERSHIP.

          1.   Should the Optionee cease to serve as a Board member for any
reason (other than death) while holding an automatic option grant under this
Article Three, then such individual shall have a three (3)-month period
following the date of such cessation of Board membership in which to exercise
such option for any or all of the shares of Common Stock for which the option
is exercisable at the time of such cessation of Board service. Such option
shall immediately terminate and cease to be outstanding, at the time of such
cessation of Board service, with respect to any shares for which the option is
not otherwise at that time exercisable.

          2.   Should the Optionee die within three (3) months after cessation
of Board service, then any automatic option grant held by the Optionee at the
time of death may subsequently be exercised, for any or all of the shares of
Common Stock for which such option is exercisable at the time of the Optionee's
cessation of Board service (less any option shares subsequently purchased by
the Optionee prior to death), by the personal representative of the Optionee's
estate or by the person or persons to whom the option is transferred pursuant
to the Optionee's will or in accordance with the laws of descent and
distribution. Any such exercise must occur within twelve (12) months after the
date of the Optionee's death.

          3.   Should the Optionee die while serving as a Board member, then
any automatic option grant held by such Optionee under this Article Three shall
accelerate in full, and the representative of the Optionee's estate or the
person or persons to whom the option is transferred upon the Optionee's death
shall have a twelve (12)-month period following the date of the Optionee's
cessation of Board membership in which to exercise such option for any or all
of the shares of Common Stock subject to that option at the time of such death,
provided the option has been outstanding for at least one (1) year at the time
of death.

          4.   In no event shall any automatic grant under this Article Three
remain exercisable after the expiration date of the ten (10)-year option term.
Upon the expiration of the applicable post-service exercise period under
subparagraph 1, 2 or 3 above or (if earlier) upon the expiration of the ten
(10)-year option term, the automatic grant shall terminate and cease to be
outstanding for any unexercised shares for which the option was otherwise
exercisable at the time of the Optionee's cessation of Board service.

       H. STOCKHOLDER RIGHTS. The holder of an automatic option grant under
this Article Three shall have none of the rights of a stockholder with respect
to any shares subject to


                                      18

<PAGE>

such option until such individual shall have exercised the option and paid 
the option price for the purchased shares.

       I. REMAINING TERMS. The remaining terms and conditions of each automatic
option grant shall be as set forth in the form Director Automatic Grant
Agreement attached as Exhibit A.

   III. CORPORATE TRANSACTION/CHANGE IN CONTROL/HOSTILE TAKE-OVER
          
        A. In the event of any Corporate Transaction and in connection with any
Change in Control of the Corporation, each automatic option grant at the time
outstanding under this Article Three shall automatically accelerate so that
each such option shall, immediately prior to the specified effective date for
the Corporate Transaction or Change in Control, as applicable, become fully
exercisable with respect to the total number of shares of Common Stock at the
time subject to such option and may be exercised for all or any portion of such
shares. Upon the consummation of the Corporate Transaction, all automatic
option grants under this Article Three shall terminate and cease to be
outstanding. Any options accelerated in connection with the Change in Control
shall remain fully exercisable until the expiration or sooner termination of
the option term.

        B. Upon the occurrence of a Hostile Take-Over, the Optionee shall have a
thirty (30)-day period in which to surrender each option held by him or her
under this Article Three to the Corporation, to the extent such option has been
outstanding for a period of at least six (6) months to the Corporation. The
Optionee shall in return be entitled to a cash distribution from the
Corporation in an amount equal to the excess of (i) the Take-Over Price of the
shares of Common Stock at the time subject to the surrendered option (whether
or not the option is otherwise at the time exercisable for such shares) over
(ii) the aggregate option price payable for such shares. Such cash distribution
shall be paid within five (5) days following the consummation of the Hostile
Take-Over. Neither the approval of the Committee nor the consent of the Board
shall be required in connection with such option surrender and cash
distribution.

        C. The shares of Common Stock subject to each option surrendered in
connection with the Hostile Take-Over shall not be available for subsequent
option grant under this Plan.

        D. The automatic option grants outstanding under this Article Three
shall in no way affect the right of the Corporation to adjust, reclassify,
reorganize or otherwise change its capital or business structure or to merge,
consolidate, dissolve, liquidate or sell or transfer all or any part of its
business or assets.

   IV. AMENDMENT OF THE AUTOMATIC GRANT PROVISIONS

          The provisions of this Automatic Option Grant Program, together with
the automatic option grants outstanding under this Article Three, may not be
amended at intervals

                                      19

more frequently than once every six (6) months, other than to the extent 
necessary to comply with applicable Federal income tax laws and regulations.

                            STOCK ISSUANCE PROGRAM
                                       
   I. TERMS AND CONDITIONS OF STOCK ISSUANCES

               Shares may be issued under the Stock Issuance Program through
direct and immediate purchases without any intervening stock option grants. The
issued shares shall be evidenced by a Stock Issuance Agreement ("Issuance
Agreement") that complies with the terms and conditions of this Article Four.

       A. CONSIDERATION.

            1. Shares of Common Stock drawn from the Corporation's authorized
but unissued shares of Common Stock ("Newly Issued Shares") shall be issued
under the Stock Issuance Program for one or more of the following items of
consideration which the Plan Administrator may deem appropriate in each
individual instance:

                     (i)  cash or check drawn to the Corporation's order;
     
                    (ii)  a promissory note payable to the Corporation's
     order in one or more installments, which may be subject to
     cancellation in whole or in part upon terms and conditions
     established by the Plan Administrator; or
     
                   (iii)  past services rendered to the Corporation or any
     parent or subsidiary corporation.
     
            2. Newly Issued Shares may, in the absolute discretion of the Plan
Administrator, be issued for consideration with a value less than one hundred
percent (100%) of the Fair Market Value of such shares at the time of issuance,
but in no event less than eighty-five percent (85%) of such Fair Market Value.

            3. Shares of Common Stock reacquired by the Corporation and held as
treasury shares ("Treasury Shares") may be issued under the Stock Issuance
Program for such consideration (including one or more of the items of
consideration specified in subparagraph 1 above) as the Plan Administrator may
deem appropriate, whether such consideration is in an amount less than, equal
to, or greater than the Fair Market Value of the Treasury Shares at the time of
issuance. Treasury Shares may, in lieu of any cash consideration, be issued
subject to such vesting requirements tied to the Participant's period of future
Service or the Corporation's attainment of specified performance objectives as
the Plan Administrator may establish at the time of issuance.

       B. VESTING PROVISIONS.

            1. Shares of Common Stock issued under the Stock Issuance Program
may, in the absolute discretion of the Plan Administrator, be fully and
immediately vested upon issuance or may vest in one or more installments over
the Participant's period of Service. The

                                      21
<PAGE>

elements of the vesting schedule applicable to any unvested shares of 
Common Stock issued under the Stock Issuance Program, namely:

           (i)  the Service period to be completed by the Participant or 
     the performance objectives to be achieved by the Corporation,

          (ii)  the number of installments in which the shares are to vest,

         (iii)  the interval or intervals (if any) which are to 
     lapse between installments, and

          (iv)  the effect which death, Permanent Disability or other 
     event designated by the Plan Administrator is to have upon the vesting 
     schedule, shall be determined by the Plan Administrator and 
     incorporated into the Issuance Agreement executed by the Corporation 
     and the Participant at the time such unvested shares are issued.

            2. The Participant shall have full stockholder rights with respect
to any shares of Common Stock issued to him or her under the Plan, whether or
not his or her interest in those shares is vested. Accordingly, the Participant
shall have the right to vote such shares and to receive any regular cash
dividends paid on such shares. Any new, additional or different shares of stock
or other property (including money paid other than as a regular cash dividend)
which the Participant may have the right to receive with respect to his or her
unvested shares by reason of any stock dividend, stock split, reclassification
of Common Stock or other similar change in the Corporation's capital structure
or by reason of any Corporate Transaction shall be issued, subject to (i) the
same vesting requirements applicable to his or her unvested shares and (ii)
such escrow arrangements as the Plan Administrator shall deem appropriate.

            3. Should the Participant cease to remain in Service while holding
one or more unvested shares of Common Stock under the Plan, then those shares
shall be immediately surrendered to the Corporation for cancellation, and the
Participant shall have no further stockholder rights with respect to those
shares. To the extent the surrendered shares were previously issued to the
Participant for consideration paid in cash or cash equivalent (including the
Participant's purchase-money promissory note), the Corporation shall repay to
the Participant the cash consideration paid for the surrendered shares and
shall cancel the unpaid principal balance of any outstanding purchase-money
note of the Participant attributable to such surrendered shares. The
surrendered shares may, at the Plan Administrator's discretion, be retained by
the Corporation as Treasury Shares or may be retired to authorized but unissued
share status.

            4. The Plan Administrator may in its discretion elect to waive the
surrender and cancellation of one or more unvested shares of Common Stock (or
other assets attributable thereto) which would otherwise occur upon the
non-completion of the vesting schedule applicable to such shares. Such waiver
shall result in the immediate vesting of the Participant's interest in the
shares of Common Stock as to which the waiver applies. Such waiver


                                      22

<PAGE>

may be effected at any time, whether before or after the Participant's
cessation of Service or the attainment or non-attainment of the applicable
performance objectives.

     II. CORPORATE TRANSACTION/CHANGE IN CONTROL

          Upon the occurrence of any Corporate Transaction or Change in
Control, all unvested shares of Common Stock at the time outstanding under the
Stock Issuance Program shall immediately vest in full.

    III. TRANSFER RESTRICTIONS/SHARE ESCROW

       A. Unvested shares may, in the Plan Administrator's discretion, be 
held in escrow by the Corporation until the Participant's interest in such 
shares vests or may be issued directly to the Participant with restrictive 
legends on the certificates evidencing such unvested shares. To the extent an 
escrow arrangement is utilized, the unvested shares and any securities or 
other assets issued with respect to such shares (other than regular cash 
dividends) shall be delivered in escrow to the Corporation to be held until 
the Participant's interest in such shares (or other securities or assets) 
vests. Alternatively, if the unvested shares are issued directly to the 
Participant, the restrictive legend on the certificates for such shares shall 
read substantially as follows:

     "THE SHARES REPRESENTED BY THIS CERTIFICATE ARE UNVESTED AND ARE 
     ACCORDINGLY SUBJECT TO (I) CERTAIN TRANSFER RESTRICTIONS AND (II) 
     CANCELLATION OR REPURCHASE IN THE EVENT THE REGISTERED HOLDER (OR 
     HIS/HER PREDECESSOR IN INTEREST) CEASES TO REMAIN IN THE CORPORATION'S 
     SERVICE. SUCH TRANSFER RESTRICTIONS AND THE TERMS AND CONDITIONS OF 
     SUCH CANCELLATION OR REPURCHASE ARE SET FORTH IN A STOCK ISSUANCE 
     AGREEMENT BETWEEN THE CORPORATION AND THE REGISTERED HOLDER (OR HIS/HER 
     PREDECESSOR IN INTEREST) DATED ____________, 199____, A COPY OF WHICH 
     IS ON FILE AT THE PRINCIPAL OFFICE OF THE CORPORATION."

       B. The Participant shall have no right to transfer any unvested shares
of Common Stock issued to him or her under the Stock Issuance Program. For
purposes of this restriction, the term "transfer" shall include (without
limitation) any sale, pledge, assignment, encumbrance, gift, or other
disposition of such shares, whether voluntary or involuntary. Upon any such
attempted transfer, the unvested shares shall immediately be cancelled, and
neither the Participant nor the proposed transferee shall have any rights with
respect to those shares. However, the Participant shall have the right to make
a gift of unvested shares acquired under the Stock Issuance Program to his or
her spouse or issue, including adopted children, or to a trust established for
such spouse or issue, provided the donee of such shares delivers to the
Corporation a written agreement to be bound by all the provisions of the Stock
Issuance Program and the Issuance Agreement applicable to the gifted shares.

     I. LOANS OR INSTALLMENT PAYMENTS

        A. The Plan Administrator may, in its discretion, assist any Optionee or
Participant (including an Optionee or Participant who is an officer or director
of the Corporation, but not an Optionee who is a member of the Primary
Committee) in the exercise of one or more options granted to such Optionee
under the Discretionary Option Grant Program or the purchase of one or more
shares issued to such Participant under the Stock Issuance Program, including
the satisfaction of any Federal and state income and employment tax obligations
arising therefrom, by (i) authorizing the extension of a loan from the
Corporation to such Optionee or Participant or (ii) permitting the Optionee or
Participant to pay the option price or purchase price for the purchased Common
Stock in installments over a period of years. The terms of any loan or
installment method of payment (including the interest rate and terms of
repayment) shall be upon such terms as the Plan Administrator specifies in the
applicable option or issuance agreement or otherwise deems appropriate under
the circumstances. Loans or installment payments may be authorized with or
without security or collateral. However, the maximum credit available to the
Optionee or Participant may not exceed the option or purchase price of the
acquired shares (less the par value of such shares) plus any Federal and state
income and employment tax liability incurred by the Optionee or Participant in
connection with the acquisition of such shares.

        B. The Plan Administrator may, in its absolute discretion, determine
that one or more loans extended under this financial assistance program shall
be subject to forgiveness by the Corporation in whole or in part upon such
terms and conditions as the Plan Administrator may deem appropriate.

   II. AMENDMENT OF THE PLAN AND AWARDS

       A. The Board has complete and exclusive power and authority to amend or
modify the Plan (or any component thereof) in any or all respects whatsoever.
However, no such amendment or modification shall adversely affect rights and
obligations with respect to options at the time outstanding under the Plan, nor
adversely affect the rights of any Participant with respect to Common Stock
issued under the Stock Issuance Program prior to such action, unless the
Optionee or Participant consents to such amendment, and (ii) any amendment made
to the Automatic Option Grant Program (or any options outstanding thereunder)
shall be in compliance with the limitation of Section IV of Article Three. In
addition, the Board may not, without the approval of the Corporation's
stockholders, amend the Plan to (i) materially increase the maximum number of
shares issuable under the Plan, except for permissible adjustments under
Section VI.C of Article One, (ii) materially modify the eligibility
requirements for Plan participation or (iii) materially increase the benefits
accruing to Plan participants.

        B. (i)  Options to purchase shares of Common Stock may be granted under
the Plan and (ii) shares of Common Stock may be issued under the Stock Issuance
Program, which are in both instances in excess of the number of shares then
available for


                                      24

<PAGE>

issuance under the Plan, provided any excess shares actually issued are 
held in escrow until stockholder approval is obtained for a sufficient 
increase in the number of shares available for issuance under the Plan. 
If such stockholder approval is not obtained within twelve (12) months 
after the date the first such excess option grants or excess share 
issuances are made, then (I) any unexercised excess options shall 
terminate and cease to be exercisable and (II) the Corporation shall 
promptly refund the purchase price paid for any excess shares actually 
issued under the Plan and held in escrow, together with interest (at 
the applicable Short Term Federal Rate) for the period the shares were 
held in escrow.

   III. TAX WITHHOLDING

        A. The Corporation's obligation to deliver shares of Common Stock upon
the exercise of stock options for such shares or the vesting of such shares
under the Plan shall be subject to the satisfaction of all applicable Federal,
state and local income tax and employment tax withholding requirements.

        B. The Plan Administrator may, in its discretion and in accordance with
the provisions of this Section III of Article Five and such supplemental rules
as the Plan Administrator may from time to time adopt (including the applicable
safe-harbor provisions of Rule 16b-3 of the Securities and Exchange
Commission), provide any or all holders of non-statutory options granted under
the Discretionary Option Grant Program or unvested shares under the Plan with
the right to use shares of Common Stock in satisfaction of all or part of the
Federal, state and local income and employment tax liabilities incurred by such
holders in connection with the exercise of their options or the vesting of
their shares (the "Taxes"). Such right may be provided to any such holder in
either or both of the following formats:

            1. STOCK WITHHOLDING: The holder of the non-statutory option or
unvested shares may be provided with the election to have the Corporation
withhold, from the shares of Common Stock otherwise issuable upon the exercise
of such non-statutory option or the vesting of such shares, a portion of those
shares with an aggregate Fair Market Value equal to the percentage of the
applicable Taxes (not to exceed one hundred percent (100%)) designated by the
holder.

            2. STOCK DELIVERY: The Plan Administrator may, in its discretion,
provide the holder of the non-statutory option or the unvested shares with the
election to deliver to the Corporation, at the time the non-statutory option is
exercised or the shares vest, one or more shares of Common Stock previously
acquired by such individual (other than in connection with the option exercise
or share vesting triggering the Taxes) with an aggregate Fair Market Value
equal to the percentage of the Taxes incurred in connection with such option
exercise or share vesting (not to exceed one hundred percent (100%)) designated
by the holder.

     IV. EFFECTIVE DATE AND TERM OF PLAN

         A. The Plan was adopted by the Board on August 11, 1993 as the 
successor to the Predecessor Plans and was approved by Cornerstone 
Technology, Inc., the sole stockholder of the Corporation, on September 
1, 1993. The Plan became effective on September 8, 1993, the


                                      25

<PAGE>

date on which the shares of the Corporation's common stock were first 
registered under Section 12(g) of the 1934 Act.

       B. Each stock option grant outstanding under the Predecessor Plans
immediately prior to the Effective Date shall be incorporated into this Plan
and treated as an outstanding option under this Plan, but each such option
shall continue to be governed solely by the terms and conditions of the
instrument evidencing such grant, and nothing in this Plan shall be deemed to
affect or otherwise modify the rights or obligations of the holders of such
options with respect to their acquisition of shares of Common Stock thereunder.
Each unvested share of Common Stock outstanding under the Predecessor Plans on
the Effective Date shall continue to be governed solely by the terms and
conditions of the instrument evidencing such share issuance, and nothing in
this Plan shall be deemed to affect or otherwise modify the rights or
obligations of the holder of such unvested shares.

       C. On February 2, 1994, the Board adopted a restatement of the Plan to
(i) increase the number of shares issuable thereunder by 400,000 shares and
(ii) impose a limitation on the maximum number of shares for which any one
individual participating in the Plan may be granted stock options and
separately exercisable stock appreciation rights after December 31, 1993. The
1994 restatement was approved by the Corporation's stockholders at the 1994
Annual Stockholders' Meeting. On January 31, 1995, the Board approved an
increase in the number of shares issuable under the Plan by 350,000 shares. The
1995 restatement was approved by the Corporation's stockholders at the 1995
Annual Stockholders' Meeting. On January 30, 1996, the Board approved (i) an
increase in the number of shares issuable under the Plan by 500,000 shares and
(ii) a 500,000-share limitation on the maximum number of shares that any
Optionee or Participant may receive in the aggregate over the term of the Plan,
exclusive of option grants or stock awards made prior to January 1, 1996. The
1996 restatement was approved by the Corporation's stockholders at the 1996
Annual Stockholders' Meeting. On February 14, 1997, the Board approved an
increase in the number of shares issuable under the Plan by 400,000 shares. The
1997 restatement was approved by the Corporation's stockholders at the 1997
Annual Stockholders' Meeting. On March 25, 1998, the Board approved an increase
in the number of shares issuable under the Plan by 200,000 shares. The 1998
restatement was approved by the Corporation's stockholders at the 1998 Annual
Stockholders' Meeting.

       D. The option/vesting acceleration provisions of Section III of Article
Two and Section III of Article Three and Section II of Article Four relating to
Corporate Transactions and Changes in Control may, in the Plan Administrator's
discretion, be extended to one or more stock options or unvested share
issuances which are outstanding under the Predecessor Plans on the Effective
Date but which do not otherwise provide for such acceleration.

       E. The Plan shall terminate upon the EARLIER of (i) August 10, 2003 or
(ii) the date on which all shares available for issuance under the Plan shall
have been issued or cancelled pursuant to the exercise, surrender or cash-out
of the options granted under the Plan or the issuance of shares (whether vested
or unvested) under the Stock Issuance Program. If the date of termination is
determined under clause (i) above, then all option grants and unvested share


                                      26

<PAGE>

issuances outstanding on such date shall thereafter continue to have force and
effect in accordance with the provisions of the instruments evidencing such
grants or issuances.

     V. USE OF PROCEEDS

          Any cash proceeds received by the Corporation from the sale of shares
pursuant to option grants or share issuances under the Plan shall be used for
general corporate purposes.

    VI. REGULATORY APPROVALS

        A. The implementation of the Plan, the granting of any option under the
Plan, the issuance of any shares under the Stock Issuance Program, and the
issuance of Common Stock upon the exercise or surrender of the option grants
made hereunder shall be subject to the Corporation's procurement of all
approvals and permits required by regulatory authorities having jurisdiction
over the Plan, the options granted under it, and the Common Stock issued
pursuant to it.

        B. No shares of Common Stock or other assets shall be issued or
delivered under this Plan unless and until there shall have been compliance
with all applicable requirements of Federal and state securities laws,
including the filing and effectiveness of the Form S-8 registration statement
for the shares of Common Stock issuable under the Plan, and all applicable
listing requirements of any securities exchange on which stock of the same
class is then listed.

   VII. NO EMPLOYMENT/SERVICE RIGHTS

   Neither the action of the Corporation in establishing the Plan, nor 
any action taken by the Plan Administrator hereunder, nor any provision 
of the Plan shall be construed so as to grant any individual the right 
to remain in the employ or Service of the Corporation (or any parent or 
subsidiary corporation) for any period of specific duration, and the 
Corporation (or any parent or subsidiary corporation retaining the 
services of such individual) may terminate such individual's employment 
or Service at any time and for any reason, with or without cause.

  VIII. MISCELLANEOUS PROVISIONS

        A. The right to acquire Common Stock or other assets under the Plan may
not be assigned, encumbered or otherwise transferred by any Optionee or
Participant.

        B. The provisions of the Plan relating to the exercise of options and
the vesting of shares shall be governed by the laws of the State of California,
as such laws are applied to contracts entered into and performed in such State.

        C. The provisions of the Plan shall inure to the benefit of, and be
binding upon, the Corporation and its successors or assigns, whether by
Corporate Transaction or otherwise, and the Participants and Optionees, the
legal representatives of their respective estates, their respective heirs or
legatees and their permitted assignees.
