                                   PROPOSAL 2
 
                 APPROVAL OF 1995 EMPLOYEE STOCK PURCHASE PLAN
 
  A proposal to approve the Company's 1995 Employee Stock Purchase Plan (the
"1995 Purchase Plan") will be presented to stockholders at the Annual Meeting.
The 1995 Purchase Plan, which was adopted by the Board of Directors of the
Company in March 1995 subject to stockholder approval, is intended to qualify
as an "employee stock purchase plan" under Section 423 of the Internal Revenue
Code of 1986, as amended (the "Code"). The 1995 Purchase Plan, which authorizes
the grant to employees of the Company and designated subsidiaries of rights to
purchase up to 2,000,000 shares of Common Stock, is intended to replace the
Company's existing Employee Stock Purchase Plan (the "Existing Purchase Plan")
upon depletion of the shares authorized for issuance under the Existing
Purchase Plan, which the Company expects to occur in August 1995.
 
  The goal of the Company is to recruit the best available talent in what it
believes to be one of the most competitive labor markets in the United States.
Equity incentives are a fundamental tool used by the Company to recruit and
retain employees. Consequently, the Board of Directors considers the adoption
of the 1995 Purchase Plan to be necessary to achieve that goal.
 
  Approval of the 1995 Purchase Plan requires the affirmative vote of the
holders of record of a majority of the shares represented and voting, in person
or by proxy, at the Annual Meeting.
 
  THE BOARD OF DIRECTORS RECOMMENDS A VOTE IN FAVOR OF THE ADOPTION OF THE 1995
PURCHASE PLAN.
 
  The persons designated in the enclosed proxy will vote your shares FOR
approval of the 1995 Purchase Plan unless instructions to the contrary are
indicated in the proxy.
 
  The essential features of the 1995 Purchase Plan are summarized below.
 
 1995 Employee Stock Purchase Plan
 
  Purpose. The purpose of the 1995 Purchase Plan is to provide employees with
an opportunity to purchase Common Stock through accumulated payroll deductions.
The Company, by means of the 1995 Purchase Plan, seeks to retain the services
of its employees, to secure and retain the services of new employees, and to
provide incentives for such persons to exert maximum efforts for the success of
the Company by providing eligible employees with an opportunity to participate
in the Company's future growth.
 
  Administration. The 1995 Purchase Plan will be administered by the Board of
Directors of the Company or by a committee appointed by the Board (the Board or
such committee being referred to as the "Plan Administrator"). The Plan
Administrator has full and exclusive discretionary authority to construe,
interpret and apply the terms of, and to determine eligibility and to
adjudicate all disputed claims filed under, the 1995 Purchase Plan. Every
finding, decision and determination made by the Plan Administrator is, to the
full extent permitted by law, final and binding on all parties.
 
                                       4
<PAGE>
 
  Available Shares. A total of 2,000,000 shares of Common Stock have been
reserved for issuance under the 1995 Purchase Plan, subject to adjustment in
the event of stock splits, stock dividends and other similar changes in the
Common Stock or the capital structure of the Company.
 
  Eligibility. All employees of the Company, and of any subsidiary of the
Company designated by the Plan Administrator, are eligible to participate in
the 1995 Purchase Plan, except that the Plan Administrator may, in its
discretion, exclude any one or more of the following classes of employees: (a)
employees whose customary employment is 20 hours or less per week; (b)
employees whose customary employment is less than five months per calendar
year; (c) employees who have been employed by the Company or by a designated
subsidiary for less than two years; and (d) highly compensated employees
(within the meaning of Section 414(q) of the Code). Non-employee directors and
persons who own, and/or own options to acquire, 5% or more of the outstanding
shares of Common Stock are not eligible to participate in the 1995 Purchase
Plan.
 
  Purchase Periods. Under the 1995 Purchase Plan, offerings will be made in
periods (each a "Purchase Period") with lengths determined by the Plan
Administrator, provided that no Purchase Period may be longer than 27 months.
Purchase Periods will commence on the dates determined by the Plan
Administrator. The Plan Administrator has the discretion to implement
overlapping Purchase Periods and to permit employees to participate
simultaneously in more than one overlapping Purchase Period. Upon establishing
each Purchase Period, the Plan Administrator will also establish (a) one or
more dates during such Purchase Period (one of which must be on the last day
thereof) on which amounts in the accounts of participating employees will be
applied to purchase shares of Common Stock (each such date an "Exercise Date"),
(b) a discount from the fair market value of the Common Stock of no less than
0% and no more than 15% (in whole percentages) (the "Applicable Discount") at
which purchases will be made during such Purchase Period, (c) the components of
participating employees' total compensation (such components, the
"Compensation") which may be contributed to participants' 1995 Purchase Plan
accounts during such Purchase Period, and (d) a maximum number of shares that
may be purchased by any participating employee on any Exercise Date (the "Per-
Participant Limit"). Upon establishing each Purchase Period, the Plan
Administrator may, in its discretion, fix a maximum number of shares that may
be purchased by all participating employees in the aggregate during any given
Purchase Period and/or on any given Exercise Date. Once fixed, the Exercise
Date or Dates, the Applicable Discount, the Compensation, the Per-Participant
Limit and any aggregate share purchase limits with respect to a given Purchase
Period may not be changed, except upon the occurrence of a Corporate
Transaction (as defined below).
 
  Replacement Purchase Periods. If, on the day following any Exercise Date, the
fair market value of the Common Stock is less than it was on the first day of
the applicable Purchase Period, the Plan Administrator may, in its discretion,
terminate such Purchase Period and enroll each participant in a newly
established Purchase Period. Upon establishment of any such replacement
Purchase Period, the Plan Administrator will fix the Exercise Date or Dates,
the Applicable Discount, the Compensation, and the Per-Participant Limit; and
may fix aggregate share purchase limits, with respect to such replacement
Purchase Period, none of which may be subsequently changed except upon the
occurrence of a Corporate Transaction (as defined below).
 
  Participation and Withdrawal. Eligible employees elect to participate by
delivering a written subscription agreement to the Company. Employees may end
their participation at any time during a Purchase Period by delivering a
written notice of withdrawal to the Company, and participation ends
automatically upon termination of their employment for any reason other than
retirement. If a participating employee retires three months or less before the
next Exercise Date of any given Purchase Period, the retiree will remain
enrolled in such Purchase Period unless he/she delivers a written notice of
withdrawal to the Company. The Plan Administrator has the discretion to change
such three-month period from time to time during the term of the 1995 Purchase
Plan, but such period shall not exceed three months.
 
  Payroll Deductions. During each Purchase Period, the Company will deduct from
the pay of each eligible employee who elects to participate in such Purchase
Period an amount specified by such employee, and credit such amounts to the
employee's account under the 1995 Purchase Plan. Such amounts may be
 
                                       5
<PAGE>
 
from 3% to 15% (in whole percentages) of such employee's Compensation. Amounts
credited to employees' accounts will not bear interest, and employees may not
make direct cash payments to their accounts. All payroll deductions received or
held by the Company under the 1995 Purchase Plan may be used by the Company for
any corporate purpose, and the Company shall not be obligated to segregate such
payroll deductions.
 
  Grant and Exercise of Purchase Rights. On the first day of each Purchase
Period, each participating employee shall be granted the right to purchase
shares of Common Stock from his/her payroll deductions. On each Exercise Date,
the purchase rights will be exercised automatically through the application of
amounts in each participant's account to purchase shares of Common Stock at a
price per share determined by applying the Applicable Discount to the lower of
(a) the fair market value of the Common Stock on the first day of the
applicable Purchase Period or (b) the fair market value of the Common Stock on
the applicable Exercise Date (in each case as adjusted for stock splits, stock
dividends and other similar changes in the Common Stock or the capital
structure of the Company); provided, however, that the Plan Administrator may,
in its discretion, determine the per share purchase price by applying the
Applicable Discount solely to the fair market value of the Common Stock on the
first day of the applicable Purchase Period (as adjusted as provided above),
but only if the Plan Administrator elects to do so at the time it establishes
such Purchase Period. The shares purchased may be newly issued shares, treasury
shares or shares acquired by the Company on the open market or otherwise. As of
March 31, 1995, the closing sale price of the Common Stock on the New York
Stock Exchange was $11.375 per share.
 
  Share Purchase Limits. In addition to any share purchase limits fixed by the
Plan Administrator, certain additional limitations on the amount of Common
Stock that may be purchased in any calendar year under the 1995 Purchase Plan
are imposed by the Code, including a requirement that no employee may purchase
in any calendar year under the 1995 Purchase Plan and any other employee stock
purchase plans of the Company, Common Stock with an aggregate fair market value
greater than $25,000.
 
  Discretion to Accelerate in Certain Circumstances. If a Corporate Transaction
(as defined below) occurs or becomes imminent, the Board of Directors has the
discretion to shorten any or all ongoing Purchase Periods by fixing a new
Exercise Date (a "New Exercise Date") with respect to such period or periods,
in which case the Board of Directors may also change the Applicable Discount,
the Compensation, the Per-Participant Limit and any aggregate share purchase
limits previously established by the Plan Administrator with respect to such
period or periods. If the Board exercises its discretion to establish a New
Exercise Date, it will notify each participant in the applicable Purchase
Period or Periods of such date, of any changes to the Applicable Discount, the
Compensation, the Per-Participant Limit and any aggregate share purchase
limits, and that the amounts held in such employee's account will be applied to
purchase Common Stock on the New Exercise Date and, if applicable, on such
changed terms, unless such employee withdraws from the Purchase Period prior
thereto. A "Corporate Transaction" means any of the following events: (a) a
Share Acquisition Date (as defined below); (b) a dissolution or liquidation of
the Company; (c) a merger or consolidation in which the Company is not the
surviving corporation; (d) a merger in which the Company is the surviving
corporation but the shares of Common Stock outstanding immediately prior to the
merger are converted by virtue of the merger into other property, whether in
the form of securities, cash or otherwise; (e) any capital reorganization in
which more than 50% of the shares of the Company entitled to vote are
exchanged; and (f) any other event that the Board deems, in its discretion, to
constitute a change in control of the Company. A "Share Acquisition Date" means
the first date of public announcement that a person (other than the Company, a
subsidiary of the Company, or an employee benefit plan of the Company or any
subsidiary) (an "Acquiring Person") has become the beneficial owner of 20% or
more of the outstanding shares of Common Stock in a transaction or series of
transactions that has not been approved by a majority of the directors of the
Company who are not affiliated with such Acquiring Person.
 
  Term and Early Termination. The 1995 Purchase Plan will become effective on
the date it is approved by the stockholders, and shall terminate ten years
after such date, unless sooner terminated by the Board of

Directors. The Board of Directors may terminate the 1995 Purchase Plan at any
time and for any reason, subject to certain restrictions on the ability to
adversely affect rights previously granted thereunder.
 
  Amendment. The Board of Directors may amend the 1995 Purchase Plan at any
time and for any reason, subject to certain restrictions on the ability to
adversely affect rights previously granted thereunder and to any legal
requirement to obtain stockholder approval.

but bears the expenses of administration.
 
 U.S. Federal Income Tax Consequences Relating to the 1995 Purchase Plan.
 
  Under the provisions of Section 423 of the Code, an employee who elects to
participate in the 1995 Purchase Plan will not realize income upon commencement
of a Purchase Period or upon issuance to him/her of shares of Common Stock,
and, except as herein described, the Company will not be entitled to any
deduction from income. If the employee retains the shares issued to him/her
under the 1995 Purchase Plan for more than two years from the first day of the
Purchase Period and for more than one year after the date of the issuance of
such shares to him/her, or if he/she dies while owning the shares, the employee
will be required to include in income as compensation, for the year in which
he/she disposes of such shares or dies, an amount equal to the lesser of (i) an
amount determined by applying the Applicable Discount to the fair market value
of such shares on the first day of the Purchase Period in which such shares
were purchased, or (ii) the excess of the fair market value of such shares at
the time of disposition or death over the purchase price. If, on the other
hand, the employee disposes of such shares within the aforesaid two-year or
one-year period, the employee will be required to include in income as
compensation for the year in which such disposition occurs an amount equal to
the excess of the fair market value of such shares on the date of purchase over
the purchase price, and the Company will be entitled to a deduction from income
equal to the amount the employee is required to include in income as
compensation. Any additional gain or loss realized upon a disposition, other
than the amounts treated as compensation, as aforesaid, will be treated as
capital gain or loss.
 
                                   PROPOSAL 3
 
                     APPROVAL OF 1995 STOCK INCENTIVE PLAN
 
  A proposal to approve the Company's 1995 Stock Incentive Plan (the "1995
Incentive Plan") will be presented to stockholders at the Annual Meeting. The
1995 Incentive Plan was adopted by the Board of Directors of the Company in
March 1995 subject to stockholder approval. The 1995 Incentive Plan, which
authorizes the grant to Eligible Individuals (as defined below) of options,
restricted stock grants or bonuses and stock appreciation rights covering up to
3,500,000 shares of Common Stock, is intended to supplement the Company's
existing 1991 Stock Incentive Plan (the "1991 Incentive Plan"). As of April 6,
1995, 1,402,768 shares of Common Stock remained eligible for issuance under the
1991 Incentive Plan.
 
  The Company, by means of the 1995 Incentive Plan, seeks to retain the
services of persons now employed by or serving as consultants or directors to
the Company, to secure and retain the services of persons capable of filling
such positions, and to provide incentives for such persons to exert maximum
efforts for the success of the Company. The Board of Directors considers the
adoption of the 1995 Incentive Plan to be necessary to achieve that goal.
 
  Approval of the 1995 Incentive Plan requires the affirmative vote of the
holders of record of a majority of the shares represented and voting, in person
or by proxy, at the Annual Meeting.
 
  THE BOARD OF DIRECTORS RECOMMENDS A VOTE IN FAVOR OF THE ADOPTION OF THE 1995
INCENTIVE PLAN.
 
  The persons designated in the enclosed proxy will vote your shares FOR
approval of the 1995 Incentive Plan unless instructions to the contrary are
indicated in the proxy.

  The essential features of the 1995 Incentive Plan are summarized below.
 
 1995 Stock Incentive Plan
 
  Purpose. The purpose of the 1995 Incentive Plan is to allow the Company to
provide incentives to Eligible Individuals (as defined below) for employment,
increased efforts and successful achievements on behalf of or in the interest
of the Company and its affiliates and to maximize the rewards due them for
those efforts and achievements.
 
  Administration. The 1995 Incentive Plan will be administered by the Board of
Directors of the Company (the "Board"), by one or more separate committees
appointed by the Board with respect to specified groups of participants (each
such committee, a "Committee"), and by the Secretary of the Company, as set
forth below. As used herein, the term "Plan Administrator" shall refer to the
Board, or any Committee, as applicable, that is administering the provisions of
the 1995 Incentive Plan being referred to.
 
  (a) With respect to awards to Eligible Individuals who are officers or
directors of the Company subject to Section 16(b) ("Section 16(b) Persons") of
the Securities Exchange Act of 1934, as amended (the "Exchange Act") and to
"covered employees" within the meaning of Section 162(m) of the Code ("Covered
Employees"), the 1995 Incentive Plan shall be administered by a Committee
constituted to comply with the rules governing a plan intended to qualify as a
discretionary plan under Rule 16b-3 or its successors under the Exchange Act
("Rule 16b-3") and a "committee comprised solely of two or more outside
directors" within the meaning of Section 162(m) of the Code.
 
  (b) With respect to awards made to Eligible Individuals who are neither
Section 16(b) Persons nor Covered Employees, the 1995 Incentive Plan may be
administered by the Board or by any Committee consisting of one or more
persons.
 
  (c) The Secretary of the Company shall administer the provisions of the 1995
Incentive Plan providing for the grant of stock options to Eligible Individuals
who are non-employee directors. This function will be limited to matters of
interpretation and administrative oversight.
 
  The Plan Administrator, except with respect to grants of stock options to
non-employee directors, shall determine the Eligible Individuals who are to
receive awards under the 1995 Incentive Plan, the timing of such awards, the
type of award and the terms thereof. The Plan Administrator shall have the sole
authority, in its absolute discretion, to adopt, amend and rescind such rules
and regulations as, in its opinion, may be advisable for the administration of
the 1995 Incentive Plan, to construe and interpret the 1995 Incentive Plan, the
rules and regulations thereof, and the instruments evidencing awards granted
thereunder, and to make all other determinations deemed necessary or advisable
for the administration of the 1995 Incentive Plan. All decisions,
determinations and interpretations of the Plan Administrator shall be binding
on all participants. Notwithstanding the foregoing, the Plan Administrator will
not exercise any discretionary functions with respect to options granted to
non-employee directors.
 
  Types of Awards. Awards under the 1995 Incentive Plan may consist of (a)
options to purchase Common Stock that are designed to qualify as "incentive
stock options" under Section 422 of the Code ("Incentive Stock Options"), (b)
options to purchase Common Stock that are not described in Sections 422 or 423
of the Code ("Non-Qualified Stock Options" and, collectively with Incentive
Stock Options, "Options"), (c) the sale or bonus grant of restricted shares of
Common Stock ("Restricted Stock"), and (d) the grant of stock appreciation
rights ("SARs"), either independently of ("Independent SARs"), or in tandem
with ("Tandem SARs"), Options.
 
  Available Shares. A total of 3,500,000 shares of Common Stock have been
reserved for issuance under the 1995 Incentive Plan, subject to adjustment in
the event of any merger, consolidation, reorganization, reincorporation, stock
split, stock dividend (in excess of 2%) or other change in the corporate
structure of the Company. Such number of shares shall be subject to adjustment
as described below.
 
                                       8
<PAGE>
 
  (a) The following awards will count against and reduce the number of shares
available under the 1995 Incentive Plan: (i) shares of Common Stock subject to
outstanding Options issued under the 1995 Incentive Plan; (ii) outstanding
shares of Restricted Stock issued under the 1995 Incentive Plan; (iii) shares
subject to Independent SARs issued under the 1995 Incentive Plan; and (iv) with
respect to Tandem SARs issued under the 1995 Incentive Plan, the number of
shares subject to such Tandem SAR or to the related Option, whichever is
greater.
 
  (b) The following shares will be added back to the number of shares available
under the 1995 Incentive Plan: (i) shares underlying Options issued under the
1995 Incentive Plan that are cancelled or terminate before being exercised;
(ii) shares of Restricted Stock issued under the 1995 Incentive Plan that are
cancelled or repurchased pursuant to their vesting restrictions; (iii) shares
underlying Independent SARs issued under the 1995 Incentive Plan that are
cancelled or terminate before being exercised; (iv) shares as to which an
Option related to a Tandem SAR issued under the 1995 Incentive Plan has been
surrendered in connection with the exercise of such Tandem SAR; and (v) shares
underlying Independent SARs issued under the 1995 Incentive Plan that are
exercised and paid in cash; but only, in each case, if the holder of such award
did not receive dividends or other benefits of ownership with respect to such
shares.
 
  Eligible Individuals. Employees, officers (including officers who are
directors of the Company), independent contractors and consultants of the
Company and any subsidiary of the Company designated by the Plan Administrator
(collectively, the "Eligible Individuals") are eligible to participate in the
1995 Incentive Plan. Non-employee directors are not eligible to receive any
awards under the 1995 Incentive Plan other than automatic nondiscretionary
stock options.
 
  Limitation on Awards. No Eligible Individual may be granted Options or SARs
covering more than 1,000,000 shares during any calendar year.
 
  Non-Discretionary Option Grants.
 
  (a) Option Grants. The 1995 Incentive Plan provides for the automatic, non-
discretionary grant of Options ("Non-Discretionary Options") covering 5,000
shares of Common Stock to each non-employee director of the Company on the date
following each annual meeting of the Company's stockholders during the term of
the 1995 Incentive Plan. Following stockholder approval of the 1995 Incentive
Plan, non-employee directors will not receive further grants of options under
the 1991 Incentive Plan.
 
  (b) Option Term. Each Non-Discretionary Option shall be evidenced by a
written stock option agreement, shall have a term of ten years (subject to
earlier termination in the circumstances described below), or such shorter term
as may be required to comply with applicable law, shall have an exercise price
no less than the fair market value of the underlying shares on the grant date,
and shall vest as to 50% of the shares covered thereby on the six-month
anniversary of the grant date, and thereafter in daily increments equal to
1/365 of such shares so that the Non-Discretionary Option becomes fully vested
on the first anniversary of the grant date. The term of each Non-Discretionary
Option will terminate early in the following circumstances: (a) if the optionee
ceases to be a director for any reason other than death, disability or cause,
the Option will terminate on the last date of the period beginning on the date
after the optionee ceases to be a director and running thereafter for a period
of time equal to the duration of such director's continuous service on the
Board (but in no event more than three years); (b) if the optionee ceases to be
a director due to death or disability, the Option will terminate on the third
anniversary of the date the optionee ceases to be a director; and (c) if the
optionee's service on the board is terminated for cause, the Option will
terminate immediately. In any of the foregoing cases, vesting of the Option
will cease on the date the optionee ceases to be a director.

  Discretionary Option Grants.
 
  (a) Option Grants. The Plan Administrator may, in its discretion, grant
Options ("Discretionary Options") to Eligible Individuals from time to time
during the term of the 1995 Incentive Plan, provided that only employees of the
Company may receive Incentive Stock Options. All grants of Discretionary
Options will be evidenced by a written option agreement.
 
  (b) Option Term. The Plan Administrator shall determine the term of any
Discretionary Option granted by it, provided that the term of any Incentive
Stock Option may not be longer than ten years, and provided further that the
term of any Incentive Stock Option granted to an Eligible Individual possessing
more than 10% of the combined voting power of the Company or an affiliate (a
"10% Holder") may not be longer than five years.
 
  (c) Number of Underlying Shares. The Plan Administrator shall determine the
number of shares underlying any Discretionary Option it elects to grant,
provided that the aggregate fair market value of all shares underlying
Incentive Stock Options granted to an Eligible Individual that first become
exercisable in any calendar year may not exceed $100,000.
 
  (d) Exercise Price. The Plan Administrator shall determine the exercise price
of any Discretionary Option it elects to grant, provided that (i) the exercise
price of Incentive Stock Options may not be less than the fair market value of
the underlying shares on the grant date, and (ii) the exercise price of any
Incentive Stock Option granted to a 10% Holder may not be less than 110% of the
fair market value of the underlying shares on the grant date.
 
  (e) Vesting. The Plan Administrator shall determine the vesting schedule, if
any, with respect to each Discretionary Option it elects to grant.
 
  Exercise of Options. The exercise price for all Options must be paid to the
Company at the time of exercise in cash, personal or certified check, bank
draft, or postal or express money order, provided that the Plan Administrator
may, in its discretion, (a) permit the exercise price of a Discretionary Option
to be paid in any one, or any combination, of the following manners: (i) with
shares of Common Stock owned by the optionee; (ii) with shares of Common Stock
withheld from the shares otherwise deliverable to the optionee upon exercise of
the Option; (iii) by delivery of an irrevocable direction to a securities
broker to sell shares of Common Stock and deliver the proceeds to the Company;
and (iv) by delivery of a promissory note with recourse, interest, security,
redemption and other terms as the Plan Administrator shall determine; and (b)
permit the exercise price of any Non-Discretionary Option to be paid in any
one, or any combination, of the manners specified in clauses (i), (ii) and
(iii) above. Any shares of Common Stock used to exercise an Option shall be
valued at their fair market value as of the exercise date. The Plan
Administrator also may, in its discretion, permit the holder of a Discretionary
Option to surrender all or part of such option in exchange for a payment (in
cash, shares of Common Stock valued at fair market value on the date of
surrender, or any combination thereof) in an amount equal to the difference
between the aggregate fair market value (as of the surrender date) and the
aggregate exercise price of the shares as to which such option is surrendered.
As of March 31, 1995, the closing sale price of the Common Stock on the New
York Stock Exchange was $11.375 per share.
 
  Reload Feature. If, upon the exercise of any Discretionary Option, shares
otherwise issuable to the optionee are withheld to satisfy the exercise price
or federal, state and local withholding tax obligations, the Plan Administrator
may, in its discretion, issue a new Option to such optionee covering the number
of shares withheld. Any such new Option will be identical to the Discretionary
Option being exercised, except that the exercise price will be equal to the
fair market value of the Common Stock as of the grant date of such new Option.
 
  Restricted Stock Awards. The Plan Administrator may, in its discretion, grant
awards of Restricted Stock to Eligible Individuals from time to time during the
term of the 1995 Incentive Plan. Each such award may be either a sale or a
bonus grant, and will be evidenced by a written Restricted Stock purchase or
bonus
 
                                       10
<PAGE>
 
agreement, as applicable. The Plan Administrator has the discretion to fix the
terms applicable to each Restricted Stock award, including without limitation
payment terms, transfer restrictions, and forfeiture, repurchase and vesting
provisions, subject only to the restrictions contained in the 1995 Incentive
Plan. The Plan Administrator may, in its discretion, condition any Restricted
Stock award on the attainment of one or more preestablished objective
performance goals meeting the requirements of Section 162(m) of the Code and
the regulations thereunder.
 
  SAR Awards. The Plan Administrator may, in its discretion, grant awards of
SARs to Eligible Individuals from time to time during the term of the 1995
Incentive Plan. Each such award will be evidenced by a written agreement, which
will specify the term of the SAR and may contain any other provisions that the
Plan Administrator deems appropriate and that are consistent with the
provisions of the 1995 Incentive Plan.
 
  Acceleration upon Change in Ownership. On the twenty-second day after any
Share Acquisition Date (as defined below), each Option, SAR, Restricted Stock
bonus or Restricted Stock purchase agreement evidencing an Option, SAR or
Restricted Stock automatically will become fully vested, nonforfeitable and
exercisable, and any Restricted Stock covered by any such agreement will be
released from all restrictions on transfer and all repurchase and forfeiture
restrictions, unless, before such twenty-second day, a majority of the
directors of the Company who are not affiliated with the Acquiring Person (as
defined below) have approved the transaction pursuant to which such person
became an Acquiring Person. A "Share Acquisition Date" means the first date of
public announcement that a person (other than the Company, a subsidiary of the
Company, or an employee benefit plan of the Company or any subsidiary) (an
"Acquiring Person") has become the beneficial owner of 20% or more of the
outstanding shares of Common Stock.
 
  Certain Other Corporate Changes. The Plan Administrator has the discretion,
to the extent permitted by applicable law, to include provisions in any
agreements evidencing awards granted under the 1995 Incentive Plan providing
that, in the event of a dissolution, liquidation, merger or consolidation of
the Company, or any other event that the Plan Administrator deems to have
effected a change in control of the Company, any such awards shall accelerate
and become fully vested, and all forfeiture and/or transfer restrictions with
respect thereto shall lapse, regardless of whether such awards are otherwise to
be assumed or replaced in connection with such event.
 
  Term and Early Termination. The 1995 Incentive Plan will become effective on
the date it receives stockholder approval, and will terminate with respect to
the grant of additional awards on the tenth anniversary thereof, unless sooner
terminated by the Board of Directors. The Board of Directors may terminate or
suspend the 1995 Incentive Plan at any time and for any reason, subject to
certain restrictions on the ability to adversely affect awards previously
granted thereunder.
 
  Amendment. The Board of Directors may amend the 1995 Incentive Plan, and any
agreements evidencing awards granted thereunder, (other than agreements
evidencing Non-Discretionary Options) at any time and for any reason, subject
to certain restrictions on the ability to adversely affect awards previously
granted thereunder and to any legal requirement to obtain stockholder approval.
Such amendments may include, without limitation, accelerating vesting
provisions of, and repricing, awards other than Non-Discretionary Options. In
addition, terms of the 1995 Incentive Plan relating to Non-Discretionary
Options may not be amended more than once every six months, except if necessary
to comport with changes in the Code, the Employee Retirement Income Security
Act of 1974, as amended, or any applicable rules and regulations thereunder.
With the holder's written consent, the Plan Administrator also may cancel any
outstanding Option or SAR or accept any outstanding Discretionary Option or SAR
in exchange for a new Discretionary Option or SAR.
 
  Rule 16b-3 Compliance. Transactions under the 1995 Incentive Plan are
intended to comply with all applicable conditions of Rule 16b-3. To the extent
any provision of the 1995 Incentive Plan, or any action of the Plan
Administrator, fails so to comply, such provision or action will be deemed null
and void to the
 
                                       11
<PAGE>
 
extent that is permitted by applicable law and that the Plan Administrator
deems advisable. If the 1995 Incentive Plan does not include any provision
required by Rule 16b-3 in order to qualify awards of Non-Discretionary Options
as awards under a non-discretionary formula within the meaning of that Rule,
such provision (other than one relating to eligibility requirements or the
price or amount of awards) will be deemed automatically to be incorporated by
reference into the 1995 Incentive Plan with respect to awards of Non-
Discretionary Options.
 
  Expenses. The Company makes no cash contributions to the 1995 Incentive Plan,
but bears the expenses of administration. In addition, the Company also will
incur cash expenses in connection with the exercise of SARs.
 
 U.S. Federal Income Tax Consequences Relating to the 1995 Incentive Plan.
 
  The following is a brief summary of the current U.S. federal income tax rules
generally applicable to the awards under the 1995 Incentive Plan.
 
  Non-Qualified Stock Options. An optionee is not subject to federal income tax
upon grant of a Non-Qualified Stock Option. At the time of exercise, the
optionee will realize ordinary income (subject to withholding) to the extent
that the then fair market value of the Common Stock exceeds the option price.
The amount of such income will constitute an addition to the optionee's tax
basis in the optioned stock. Sale of the shares will result in capital gain or
loss (long-term or short-term depending on the optionee's holding period). The
Company is entitled to a business expense deduction at the same time and to the
same extent that the optionee realizes ordinary income.
 
  Incentive Stock Options. Incentive Stock Options awarded under the 1995
Incentive Plan are intended to constitute "incentive stock options" under
Section 422 of the Code. An optionee is not subject to federal income tax upon
either the grant or exercise of an Incentive Stock Option. If the optionee
holds the shares acquired upon exercise for at least one year after issuance of
the optioned shares and until at least two years after grant of the option,
then the difference between the amount realized on a subsequent sale or other
disposition of shares and the option price will constitute long-term capital
gain or loss. The Company will not be entitled to any deduction with respect to
the grant or exercise of an Incentive Stock Option.
 
  If the optionee sells the shares acquired under an Incentive Stock Option
before the requisite holding period, he/she will be deemed to have made a
"disqualifying disposition" of the shares and will realize ordinary income in
the year of disposition equal to the lesser of the fair market value of the
shares at exercise or the amount realized on their disposition over the option
price of the shares. Any gain recognized upon a disqualifying disposition in
excess of the ordinary income portion will constitute either short-term or
long-term capital gain. In the event of a disqualifying disposition, the
Company will be entitled to a business expense deduction in the amount of the
ordinary income realized by the optionee.
 
  The option spread on the exercise of an Incentive Stock Option is an
adjustment in computing alternative minimum taxable income. No adjustment is
required, however, if the optionee made a disqualifying disposition of the
shares in the same year as he/she is taxed on the exercise.
 
  Stock Appreciation Rights. An optionee is not taxed upon the grant of SARs.
An optionee exercising SARs will realize ordinary income (subject to
withholding) in the amount of the cash or the fair market value of the shares
received. The Company will be entitled to a business expense deduction at the
same time and to the same extent that the optionee realizes ordinary income.
 
  Restricted Stock. An awardee of Restricted Stock will generally realize
ordinary income (subject to withholding) when and to the extent that the
restrictions on the shares lapse, as measured by the value of the shares at the
time of lapse. The awardee's holding period for the shares will not commence
until the date of lapse, and dividends paid during the restriction period will
be treated as compensation. The income realized on lapse of the restrictions
will constitute an addition to the awardee's tax basis in the shares.
 
                                       12
<PAGE>
 
  In lieu of deferred recognition of income, the awardee may formally elect,
within 30 days of the award, to realize income at the time of award, as
measured by the fair market value of the stock on the date of the award
determined without regard to the restrictions. The income realized will
constitute an addition to the tax basis of the shares. In the case of such
election, any appreciation (or depreciation) on the shares during the
restriction period will give rise to capital gain (or capital loss). In the
event that the awardee terminates employment during the restriction period and
forfeits his/her shares, no deduction may be claimed and the taxes paid on
award of the shares shall be forfeited.
 
  The Company will be entitled to a business expense deduction at the same time
and to the same extent that the awardee realizes ordinary income.

                          RATIFICATION OF SELECTION OF
                         INDEPENDENT PUBLIC ACCOUNTANTS
 
  The Board of Directors has selected Arthur Andersen LLP as the Company's
independent public accountants for the fiscal year ending December 31, 1995,
and has further directed that management submit the selection of independent
public accountants for ratification by the stockholders at the Annual Meeting.
Arthur Andersen LLP has audited the Company's financial statements annually
since the Company's inception. Its representatives are expected to be present
at the Annual Meeting, will have the opportunity to make a statement if they
desire to do so and will be available to respond to appropriate questions.
 
  Stockholder ratification of the selection of Arthur Andersen LLP as the
Company's independent public accountants is not required by the Company's By-
Laws or otherwise. The Board of Directors is submitting the selection of Arthur
Andersen LLP to the stockholders for ratification as a matter of good corporate
practice. In the event the stockholders fail to ratify the selection, the Board
of Directors will reconsider whether or not to retain that firm. Even if the
selection is ratified, the Board of Directors in its discretion may direct the
appointment of a different independent accounting firm at any time during the
year if the Board of Directors determines that such a change would be in the
best interests of the Company and its stockholders.

  Section 16(a) of the Exchange Act requires the Company's directors and
executive officers, and persons who own more than ten percent of the Company's
Common Stock, to file reports of securities ownership and changes in such
ownership with the Securities and Exchange Commission. Directors, executive
officers, and greater than ten percent shareholders are required to furnish
the Company with copies of all Section 16(a) forms that they file. Based upon
a review of these filings and written representations from the Company's
directors and executive officers for the fiscal year ended December 31, 1994,
the Company notes that in connection with Mr. Johannsmeier's retirement from
the Board of Directors in May 1994, Mr. Johannsmeier's stock options expired
unexercised in August 1994. No Form 5 was filed as required in February 1995
reporting this expiration, but a Form 4 reporting this expiration was filed in
March 1995.

(1) Granted at fair market value on the date of grant; vesting over five years
    with 10% of the shares vesting six months after the date of grant and the
    balance vesting daily over the remaining term. Vesting may be accelerated
    and the options may be repriced at the discretion of the Board of
    Directors. In the event of a dissolution, merger or other reorganization
    of the Company in which more than 50% of the Company's stock is exchanged,
    any surviving corporation shall assume the options outstanding, substitute
    similar rights for outstanding options, or the options shall continue. If
    the surviving corporation refuses to assume or continue the options,
    vesting on such options shall be accelerated.
(2) The dollar amounts under these columns are the result of calculations at
    the 5% and 10% annual rates of stock appreciation prescribed by the
    Securities and Exchange Commission and are not intended to forecast
    possible future appreciation, if any, of the Company's stock price.
    Assuming 5% and 10% compounded annual appreciation of the stock price over
    the term of the option, the price of a share of Common Stock underlying an
    option issued February 24, 1994 with an exercise price of $11.50 would be
    $18.73 and $29.83, respectively, on February 24, 2004, and the price of a
    share of Common Stock underlying an option issued November 18, 1994 with
    an exercise price of $16.75 would be $27.28 and $43.45, respectively, on
    November 18, 2004. The share price of Acuson stock on December 30, 1994
    was $16.25.

               REPORT OF THE COMPENSATION COMMITTEE AND BOARD OF
                       DIRECTORS--EXECUTIVE COMPENSATION
 
  The Company believes that compensation of the Company's key executives should
be sufficient to attract and retain highly qualified personnel in the
competitive Silicon Valley area, and should also provide meaningful incentives
for measurably superior performance. The Company seeks to reward achievement of
long and short-term performance goals measured by successful development of new
products, sales volume, meeting or exceeding financial targets, and other
factors. In addition, the Company's performance is considered on an absolute
basis and in comparison to other ultrasound companies in determining executive
remuneration.
 
  The Company's executive compensation generally consists of a base salary, a
cash bonus and long-term incentive compensation in the form of stock options.
For 1994, salaries for the Company's executive officers, other than for the
President, were recommended by the President, reviewed by the Chairman of the
Board and approved by the Compensation Committee. The 1994 salary for the
President was recommended by the Chairman of the Board and approved by the
Compensation Committee. In determining his recommendations for salaries of
executive officers, the President did not employ a formulaic approach or assign
a predetermined weight to any specific objective or subjective criteria.
Rather, the President relied on a number of factors he deemed important in
making his recommendation, including his view of the Company's performance, the
ultrasound market in general and the value of that executive's position at
Acuson. The President also relied on publicly available executive compensation
surveys chosen for their reputability and relevance to the Company in terms of
geographical area and size of companies surveyed and on a study of executive
compensation in publicly-held ultrasound companies and high technology
companies in the San Francisco Bay Area. Neither the surveys nor the study
specifically use data for the companies included in the groups listed in the
performance graph in this proxy statement.
 
  The 1994 salary for Dr. Maslak, the Company's President and Chief Executive
Officer, was determined using a similar process and philosophy as was used for
all other executive officers. Generally, the Chairman of the Board considered
the survey data described above in concert with his own assessment of the
Company's performance and Dr. Maslak's performance and contributions to the
Company. There was no formulaic tie between the Company's stated goals and
performance and the President's salary in the Chairman's recommendation;
instead the Chairman's judgment and discretion was used in his recommendations
to the Compensation Committee.
 
  The Compensation Committee met in February 1994 to determine executive
officer salaries for 1994. The President reported that survey data received
placed the Company's officers' salary compensation, including bonuses, between
the 50th and 75th percentile of executive compensation for high technology
companies of a similar size in the Northern California area. The President then
noted that weak worldwide economic conditions, together with uncertainties
about United States governmental health care reimbursement as well as health
care reform and consolidations in general, would continue to impact sales in
ultrasound markets. Further, the President reported that the Company would
continue to make substantial investments in field operations and product
development, which would have an immediate effect on profits for the year.
Given these factors, the President recommended, and the Compensation Committee
accepted, that a 4.5% target salary raise be established for all executive
officers, other than the President. This 4.5% target is equal to the amount of
the Company's average "merit budget" for 1994 for the Company's employees as a
whole. (The Company's "merit budget" is the percentage raise that the Company
allocates in its budget planning process for merit salary increases for the
Company's employees as a whole; thus, while individual merit raises might vary,
all salary merit raises for employees must average 4.5%.) The President then
recommended that raises in the salaries of certain selected officers be greater
than 4.5% based, in some cases on the officers being promoted, in some cases on
the President's assessment of the officer's individual performance during 1993
and in some cases on an adjustment in base salary due to the addition or
deletion of the potential for a bonus based on sales results. The Committee
accepted these recommendations. The Chairman of the Board then recommended that
although the President's individual performance merited a higher raise, in
light of the factors described above affecting the Company as a whole, the
President's salary increase should be limited to the Company's average "merit
budget" for 1994 for employees as a whole, 4.5%, and the Compensation Committee
accepted that recommendation. Dr. Maslak's 1994 total cash compensation is
between the 50th and 75th percentile of the total cash compensation, including
bonuses, of CEOs in the survey data.
 
                                       18

  Officer bonuses for 1994 were determined in February 1995. Due to the
retirement of two of the three members of the 1994 Compensation Committee, the
Board of Directors determined officer bonuses for 1994. Under the terms of the
Company's Officer Bonus Plan, the target bonus for any officer is 25% of the
officer's cash compensation. This target is not established on an annual basis.
The amount of any particular annual bonus awarded under the Bonus Plan, other
than for the President, is recommended by the President based on his assessment
of the achievement of Company goals in the areas of financial results,
including orders, shipments and profit margins, relative market share, meeting
in a timely manner product development milestones and expense controls. These
goals are not formally established at any point in time and no specific target
amounts are included in these goals, but they are discussed on a subjective
basis with the Board at the time the Board considers the bonuses. The President
reviews the Company's performance in these areas in light of his assessment of
overall market conditions, as well as his assessment of the officer's
performance during the prior year. For 1994, the President reported to the
Board that sales for the Company had increased compared to 1993; the Company
had successfully controlled expenses; the Company's net income had been
significantly higher than its publicly-held competitors that reported
ultrasound financial results; and the Company believes it maintained its
overall market share in an increasingly competitive market. Based on these
factors, the President recommended that bonuses of 6% of salary for all
executive officers other than the President be granted, with the exception of
certain officers, who, because of exceptional performance, should be granted a
larger bonus. Dr. Maslak then requested that he receive no bonus for 1994. The
Board accepted these recommendations.
 
  The Company also has a merit bonus program that applies to employees
(including officers) to recognize special accomplishments or significant
efforts. The President has the discretion to grant a bonus to any officer
consistent with the principles of this program. No bonuses were awarded to
executive officers under this program in 1994.
 
  Stock options are awarded to provide incentives to the officers to improve
long-term financial results and to align rewards for officers with long-term
increased value for shareholders. For 1994, the President relied on the survey
and study data described above in determining the overall size of the pool of
shares available for option grants to officers as a whole. According to this
data, the overall pool of shares allocated for officer grants was in the middle
of the range for officer option grants among the companies in the survey data.
The President's recommendation of which individual officers should receive
grants of options and the size of those grants were based primarily on his view
of individual performance, and, to a lesser extent, on his evaluation of the
relative importance of that individual in meeting the Company's objectives, and
on advice from the Company's Employee Relations department on compensation
necessary to hire and retain senior executives in the Silicon Valley area. The
Compensation Committee, for options granted in February 1994, and the Board of
Directors, for options granted in November 1994, accepted all of his
recommendations. The President did not receive an option grant during 1994.
 
  Internal Revenue Code Section 162(m) limits the deductibility of annual
compensation in excess of one million dollars paid to any of the five most
highly compensated executive officers of the Company. This provision excludes
certain forms of "performance-based compensation" from the compensation taken
into account for purposes of that limit. The Company believes that its stock
incentive plans are deemed "performance-based" under the rules contained in the
proposed IRS regulations, and as a result, the Company believes that all
compensation payments in 1994 are fully deductible. The Company will review the
final regulations and determine whether any action is appropriate with regard
to the deductibility of compensation payments in later years.

                             COMPENSATION COMMITTEE
                      INTERLOCKS AND INSIDER PARTICIPATION
 
  During 1994, the Compensation Committee consisted of Messrs. Perkins and
Diener, and until May 1994, Mr. Johannsmeier, none of whom has ever been an
officer or employee of the Company.
 
                  CERTAIN RELATIONSHIPS AND OTHER TRANSACTIONS
 
  In connection with Dr. Freund's relocation to California in April 1989, the
Company loaned Dr. Freund a total of $600,000 under two separate loans to
assist him in the purchase of a home in California. The two loans, one in the
amount of $500,000 and the other in the amount of $100,000, were secured by Dr.
Freund's residence.
 
  The $500,000 loan to Dr. Freund was interest-free and was to be fully
forgiven on a daily basis over a seven year period which commenced on June 1,
1990. Pursuant to the Employment and Non-Competition Agreement described below,
at 1994 year-end, the remaining balance of the $500,000 loan was forgiven in
full. The largest aggregate amount outstanding during the year was
approximately $243,548.
 
  The $100,000 loan to Dr. Freund was paid in full by Dr. Freund in April 1994.
Under its terms, the loan was interest-free until May 1, 1994, at which time it
would bear interest at 11.25% per year.
 
  In December 1994, Dr. Freund resigned his employment with the Company. In
connection with his resignation, Dr. Freund and the Company entered into an
Employment and Non-Competition Agreement whereby Dr. Freund agreed to serve as
a consultant to the Company until June 30, 1995 and until that date, Dr. Freund
agreed he would not obtain employment with or provide consulting services to
any third party engaged in the manufacture and/or sale of medical diagnostic
ultrasound imaging equipment. In exchange, the Company agreed to forgive all
amounts then outstanding under the $500,000 loan described above; to pay on an
after-tax basis any amounts Dr. Freund paid to continue his existing Company-
provided health insurance covering him and his family pursuant to COBRA until
June 30, 1995, and on January 6, 1995 to pay Dr. Freund the sum of $163,150.
 
  In connection with Mr. Dugan's relocation to the San Francisco Bay Area in
August 1991, the Company loaned Mr. Dugan $400,000 to assist him in the
purchase of a home in the San Francisco Bay Area. The loan is secured by Mr.
Dugan's residence.
 
  The loan to Mr. Dugan is interest-free and will be fully forgiven on a daily
basis over a seven year period which commenced on August 8, 1991. The loan will
be automatically forgiven upon termination of Mr. Dugan's employment by the
Company without "cause" as defined in the promissory note, Mr. Dugan's death,
reduction of Mr. Dugan's salary below $200,000, or a "change in control" of the
Company, as defined in the note. If Mr. Dugan voluntarily terminates his
employment with the Company or if he is terminated by the Company for "cause,"
he must repay the outstanding balance of the loan plus any tax savings to him
resulting from any repayment of the loan, no later than the second anniversary
of the date of termination.
 
  As of December 31, 1994, approximately $183,188 of the loan to Mr. Dugan was
outstanding and the largest aggregate amount outstanding during the year was
approximately $262,156.
 
  Upon Mr. Abbott's retirement as Senior Executive Vice President of the
Company in June 1994, the Company entered into a two-year agreement with Mr.
Abbott pursuant to which Mr. Abbott agreed to provide consulting services to
the Company for an annual consulting fee of $234,000 in the first year and
$156,000 in the second year. In addition, pursuant to that agreement, the
Company agreed to reimburse Mr. Abbott for his reasonable out-of-pocket
expenses in performing his consulting services and to accelerate vesting of
certain options held by Mr. Abbott.

       3.   Eligibility.
            ----------- 

       (a) Any Employee who has been continuously employed by the Company prior
to the applicable Enrollment Date for such minimum period of time (not to exceed
two years), if any, as the Plan Administrator may require and who is employed by
the Company on such Enrollment Date shall be eligible to participate in the Plan
for the Purchase Period commencing with such Enrollment Date.  Members of the
Board who are eligible Employees are permitted to participate in the Plan except
to the extent limited by paragraph 13(b).

       (b) Any provisions of the Plan to the contrary notwithstanding, no
Employee shall be granted purchase rights under the Plan (i) if, immediately
after the grant, such Employee (taking into account stock owned by any other
person whose stock would be attributed to such Employee pursuant to Section

purchase stock possessing five percent (5%) or more of the total combined voting

been employed by the Company or any Designated Subsidiary for less than two

414(q) of the Code).

       4.   Purchase Periods.
            ---------------- 

       (a) The Plan shall be implemented by Purchase Periods until such time as
(i) the maximum number of shares of Common Stock available for issuance under
the Plan shall have been purchased or (ii) the Plan shall have terminated in
accordance with paragraph 19 or paragraph 24 hereof. Each Purchase Period shall
be of such duration (not to exceed twenty-seven months per Purchase Period) as
determined by the Plan Administrator upon establishment of such Purchase Period.
Purchase Periods will commence on such dates as may be determined by the Plan
Administrator during the period in which the Plan remains in existence.  The
Plan Administrator shall have the discretion to establish overlapping Purchase
Periods.

       (b) Upon establishing each Purchase Period, the Plan Administrator shall
fix (i) one or more Exercise Dates with respect to such Purchase Period, one of
which shall be on the last day of such Purchase Period, (ii) the Applicable
Discount with respect to such Purchase Period, (iii) the Compensation with
respect to such Purchase Period and (iv) the maximum number of shares that may
be purchased by any Participant on any Exercise Date during such Purchase Period
(the "Per-Participant Limit").  In addition, the Plan Administrator may, in its
discretion, fix a maximum number of shares of Common Stock that may be purchased
by all Participants in the aggregate during such Purchase Period and/or on any
given Exercise Date therein.  Once fixed, the Exercise Date or Dates, the
Applicable Discount, the 

                                      -3-
<PAGE>
 
Compensation, the Per-Participant Limit and any aggregate share purchase limits
with respect to a given Purchase Period may not be changed, except upon the
occurrence of a Corporate Transaction as provided in paragraph 18(b).

       (c) A Participant shall be granted a separate purchase right for each
Purchase Period in which he/she participates. The purchase right shall be
granted on the first day of the Purchase Period and shall be automatically
exercised in successive installments on each Exercise Date during the Purchase
Period.

       (d) If the Plan Administrator establishes overlapping Purchase Periods,
the Plan Administrator may, in its discretion, permit Participants to
participate in more than one Purchase Period at a time.

       (e) If on the Trading Day following any Exercise Date in a Purchase
Period the Fair Market Value of the Common Stock is less than the Fair Market
Value of the Common Stock on the first day of such Purchase Period (after taking
into account any adjustment during the Purchase Period pursuant to paragraph
18(a)), the Plan Administrator may, in its discretion, provide that the Purchase
Period shall be terminated and that all Participants therein shall be enrolled
in a new Purchase Period, other than any such Participants who are not eligible
to participate in the Plan on that date or who have elected to terminate
participation in the Plan.  Any such new Purchase Period (a "Replacement
Purchase Period") shall be established by the Plan Administrator pursuant to
paragraph 4(a) and shall commence on the date that such previous Purchase Period
is terminated.  The Plan Administrator shall fix one or more Exercise Dates, the
Applicable Discount, the Compensation and the Per-Participant Limit, and may fix
aggregate share purchase limits, pursuant to paragraph 4(b) with respect to such
Replacement Purchase Period.

       (f) Except as specifically provided herein, the acquisition of Common
Stock through participation in the Plan for any Purchase Period shall neither
limit nor require the acquisition of Common Stock by a Participant in any
subsequent Purchase Period.

       5.   Participation.
            ------------- 

       (a) An eligible Employee may become a Participant in the Plan by
completing a subscription agreement authorizing payroll deductions in a form
designated by the Company and filing it with the Company's payroll office prior
to the Enrollment Date for the Purchase Period in which such participation will
commence in accordance with the filing deadline established by the Company.
Such agreement will remain effective under subsequent Purchase Periods unless
and until such Employee files a new agreement or terminates his/her
participation in the Plan in accordance with paragraph 6(c), provided that such
Employee must file a new subscription agreement to enroll in any Purchase Period
that overlaps with a Purchase Period in which such Employee has previously
enrolled.

       (b) Payroll deductions for a Participant shall commence with the first
payroll following the Enrollment Date and shall end on the last complete payroll
period during the Purchase Period, unless sooner terminated by the Participant
as provided in paragraph 10.

       6.   Payroll Deductions.
            ------------------ 

       (a) At the time a Participant files his/her subscription agreement,
he/she shall elect to have payroll deductions made on each pay day during the
Purchase Period in an amount from three to fifteen percent (in whole percentages
only) of the Compensation which he/she receives on each such pay day.

       (b) All payroll deductions made for a Participant shall be credited to
his/her account under the Plan.  A Participant may not make any additional
payments into such account.

                                      -4-
<PAGE>
 
       (c) A Participant may discontinue his/her participation in the Plan as
provided in paragraph 10.  A Participant's subscription agreement shall remain
in effect for successive Purchase Periods unless and until such Participant
files a new agreement or terminates his/her participation in the Plan as
provided in paragraph 10.  The Plan Administrator may, in its discretion, permit
Participants to amend their subscription agreements to increase and/or decrease
the rate of their payroll deductions during any given Purchase Period.

       (d) Notwithstanding the foregoing, to the extent necessary to comply with
Section 423(b)(8) of the Code and paragraph 3(b) herein, a Participant's payroll
deductions may be decreased to 0% at such time during any Purchase Period which
is scheduled to end during the current calendar year (the "Current Purchase
Period") that the aggregate of all payroll deductions which were previously used
to purchase stock under the Plan in any other Purchase Period that ended or that
will end during that calendar year plus all payroll deductions accumulated with
respect to the Current Purchase Period equal the maximum amount permitted under
Section 423 of the Code.  Payroll deductions shall recommence at the rate
provided in such Participant's subscription agreement at the beginning of the
first Purchase Period which is scheduled to end in the following calendar year,
unless terminated by the Participant as provided in paragraph 10.

       7.   Grant of Purchase Right.  On the first day of each Purchase Period,
            -----------------------                                            
each Participant in such Purchase Period shall be granted the right to purchase
on each Exercise Date of such Purchase Period (at the applicable Purchase Price)
up to a number of shares of Common Stock determined by dividing such
Participant's payroll deductions accumulated prior to such Exercise Date and
retained in the Participant's account as of the Exercise Date by the applicable
Purchase Price; provided that such purchase shall be subject to the limitations
set forth in paragraphs 3(b), 4(b), 6(d), 8(b) and 12(a) hereof.  Exercise of
the purchase right shall occur as provided in paragraph 8, unless the
Participant has withdrawn from the Plan pursuant to paragraph 10, and the
purchase right, to the extent not exercised, shall expire on the last day of the
Purchase Period.

       8.   Exercise of Purchase Right.
            -------------------------- 

       (a) Unless a Participant withdraws from the Plan as provided in paragraph
10 below, his/her right to purchase shares will be exercised automatically on
each Exercise Date, and the maximum number of full shares subject to such right
shall be purchased for such Participant at the applicable Purchase Price with
the accumulated payroll deductions in his/her account.  No fractional shares
will be purchased; any payroll deductions accumulated in a Participant's account
which are not sufficient to purchase a full share shall be carried over to the
next Exercise Date under the Plan or returned to the Participant, provided that,
if the next Exercise Date falls within a new Purchase Period, such payroll
deductions shall be carried over to such Exercise Date only if the Participant
participates in such new Purchase Period.  Any amount remaining in a
Participant's account at the close of any Exercise Date caused by anything other
than a surplus due to fractional shares (including the accumulated payroll
deductions in any Participant's account as of any Exercise Date that are in
excess of the amount needed to purchase the maximum number of full shares which
may be purchased by such Participant based on the limitations in paragraphs
3(b), 4(b), 6(d), 8(b) and 12(a) hereof) shall be refunded to the Participant in
cash as soon as practicable and shall not be carried over to the next Exercise
Date.  During a Participant's lifetime, a Participant's right to purchase shares
hereunder is exercisable only by him/her.

       (b) If, on a given Exercise Date, the aggregate purchase of shares upon
the exercise in full of all purchase rights would exceed the aggregate share
purchase limit, if any, fixed by the Plan Administrator pursuant to paragraph
4(b) with respect to the applicable Purchase Period, the Company shall make a
pro-rata allocation of the available shares in as nearly uniform a manner as
shall be practicable and as it shall determine to be equitable.

       9.   Delivery.  The Company shall arrange the delivery to each
            --------                                                 
Participant of a certificate representing the shares of Common Stock purchased
upon exercise of his/her purchase right based upon instructions provided to the
Company by the Participant from time to time, but subject to paragraph 12(c).

       10   Withdrawal; Termination of Employment.
            ------------------------------------- 

       (a) A Participant may withdraw all but not less than all the payroll
deductions credited to his/her account and not yet used to exercise his/her
purchase right under the Plan at any time by giving written notice to the
Company in a form designated by the Company.  All of the Participant's payroll
deductions credited to his/her account will be paid to such Participant as soon
as practicable after receipt of such notice of withdrawal.  Upon receipt of such
notice of withdrawal, the Participant's purchase right for the Purchase Period
will be automatically terminated, and no further payroll deductions for the
purchase of shares will be made during the Purchase Period.  If a Participant
withdraws from a Purchase Period, payroll deductions will not resume at the
beginning of the succeeding Purchase Period unless the Participant delivers to
the Company a new subscription agreement.

       (b) Upon a Participant's ceasing to be an eligible Employee for any
reason other than retirement, the payroll deductions credited to such
Participant's account during the Purchase Period but not yet used to exercise
his/her purchase right will be returned to such Participant or, in the case of
his/her death, to the person or persons entitled thereto under paragraph 14, and
such Participant's purchase right will be automatically terminated.

       (c) Upon a Participant's ceasing to be an eligible Employee by reason of
his/her retirement, the provisions of this paragraph 10(c) shall apply.  If such
retirement occurs three months or less prior to the next Exercise Date, the
retired Participant shall have the option of withdrawing from the Plan as
provided in paragraph 10(a), or taking no action and thereby continuing
participation in the Purchase Period in which he/she was participating at the
time of retirement.  If retirement occurs more than three months prior to the
next Exercise Date, the payroll deductions credited to such retired
Participant's account during the Purchase Period but not yet used to exercise
his/her purchase right will be returned to such Participant and such
Participant's purchase right will be automatically terminated.  The Plan
Administrator shall have the discretion to shorten or lengthen such period from
time to time during the term of the Plan, but such period shall in no event
exceed three months.

       11.  Interest.  No interest shall accrue on the payroll deductions of a
            --------                                                          
Participant in the Plan.

       12.  Stock.
            ----- 

       (a) The maximum number of shares of the Company's Common Stock which
shall be made available for sale under the Plan shall be 2,000,000 shares,
subject to adjustment upon changes in capitalization of the Company as provided
in paragraph 18.  If on a given Exercise Date the aggregate number of shares
with respect to which purchase rights are to be exercised exceeds the number of
shares then available under the Plan, the Company shall make a pro rata
allocation of the shares remaining available for purchase in as uniform a manner
as shall be practicable and as it shall determine to be equitable.  If any
purchase right granted under the Plan shall terminate for any reason without
having been exercised, the Common Stock not purchased under such right shall
again become available under the Plan.

       (b) A Participant will have no interest or voting right in shares covered
by his/her purchase right until such shares are actually purchased on the
Participant's behalf in accordance with the applicable provisions of the Plan.
No adjustment shall be made for dividends, distributions or other rights for
which the record date is prior to the date of such purchase.

       (c) Shares to be delivered to a Participant under the Plan will be
registered in the name of the Participant, in the name of the Participant and
his/her spouse, in the name of the stockbroker at which the Participant
maintains an account in accordance with instructions provided to the Company by
the Participant pursuant to paragraph 9 or in the name of any permitted
transferee of the Participant pursuant to paragraph 15.

                                      -6-
<PAGE>
 
       (d) The Common Stock subject to the Plan may be unissued shares, treasury
shares or shares purchased by the Company on the open market or otherwise.

       13.  Administration.
            -------------- 

       (a) The Plan shall be administered by the Plan Administrator, which shall
have full and exclusive discretionary authority to construe, interpret and apply
the terms of the Plan, to determine eligibility and to adjudicate all disputed
claims filed under the Plan. Every finding, decision and determination made by
the Plan Administrator shall, to the full extent permitted by law, be final and
binding upon all parties.

       (b) Notwithstanding the provisions of paragraph 13(a), in the event that
Rule 16b-3 promulgated under the Exchange Act or any successor provision ("Rule
16b-3") provides specific requirements for the administrators of plans of this
type, the Plan shall be only administered by such a body and in such a manner as
shall comply with the applicable requirements of Rule 16b-3.  Unless permitted
by Rule 16b-3, no discretion concerning decisions regarding the Plan shall be
afforded to any committee or person that is not "disinterested" as that term is
used in Rule 16b-3.

       14.  Designation of Beneficiary.
            -------------------------- 

       (a) Participants may file a written designation of a beneficiary, on a
form designated by the Company, who is to receive any shares and cash, if any,
from the Participant's account under the Plan in the event of such Participant's
death.  If a Participant is married and the designated beneficiary is not the
spouse, spousal consent shall be required for such designation to be effective.

       (b) Such designation of beneficiary may be changed by the Participant
(and his/her spouse, if any) at any time by written notice.  In the event of the
death of a Participant and in the absence of a beneficiary validly designated
under the Plan who is living at the time of such Participant's death, the
Company shall deliver such shares and/or cash to the executor or administrator
of the estate of the Participant, or if no such executor or administrator has
been appointed (to the knowledge of the Company), the Company, in its
discretion, may deliver such shares and/or cash to the spouse or to any one or
more dependents or relatives of the Participant, or if no spouse, dependent or
relative is known to the Company, then to such other person as the Company may
designate.

       15.  Transferability.  Neither payroll deductions credited to a
            ---------------                                           
Participant's account nor any rights with regard to the exercise of a purchase
right or to receive shares under the Plan may be assigned, transferred, pledged
or otherwise disposed of in any way (other than by will, the laws of descent and
distribution or as provided in paragraph 14 hereof) by the Participant. Any such
attempt at assignment, transfer, pledge or other disposition shall be without
effect, except that the Company may treat such act as an election to withdraw
funds from a Purchase Period in accordance with paragraph 10.

       16.  Use of Funds.  All payroll deductions received or held by the
            ------------                                                 
Company under the Plan may be used by the Company for any corporate purpose, and
the Company shall not be obligated to segregate such payroll deductions.

       17.  Reports.  Individual accounts will be maintained for each
            -------                                                  
Participant in the Plan.  Such accounts will be unfunded.  Statements of account
will be given to Participants as soon as practicable following each Exercise
Date, which statements will set forth the amounts of payroll deductions, the
Purchase Price, the number of shares purchased and the remaining cash balance,
if any.

       18.  Adjustments Upon Changes in Capitalization or Ownership.
            ------------------------------------------------------- 

       (a) Subject to any required action by the shareholders of the Company,
the Reserves, as well as the Purchase Price with respect to each purchase right
under the Plan that has not yet been 

                                      -7-
<PAGE>
 
exercised, shall be proportionately adjusted for any increase or decrease in the
number of issued shares of Common Stock resulting from a stock split, reverse
stock split, stock dividend, combination or reclassification of the Common
Stock, or any other increase or decrease in the number of shares of Common Stock
effected without receipt of consideration by the Company; provided, however,
that conversion of any convertible securities of the Company shall not be deemed
to have been "effected without receipt of consideration." Such adjustment shall
be made by the Plan Administrator, whose determination in that respect shall be
final, binding and conclusive. Except as expressly provided herein, no issuance
by the Company of shares of stock of any class, or securities convertible into
shares of stock of any class, shall affect, and no adjustment by reason thereof
shall be made with respect to, the number or price of shares of Common Stock
subject to purchase rights granted under the Plan. The Plan Administrator may,
if it so determines in the exercise of its sole discretion, make provision for
adjusting the Reserves, as well as the price per share of Common Stock covered
by each outstanding purchase right, in the event the Company effects one or more
reorganizations, recapitalizations, rights offerings or other increases or
reductions of shares of its outstanding Common Stock.

       (b) In the event that any Corporate Transaction occurs or becomes
imminent, the Board may determine, in the exercise of its sole discretion, to
shorten any Purchase Period or Purchase Periods then in progress by setting a
new Exercise Date (the "New Exercise Date").  If it elects to fix a New Exercise
Date, the Board also may, in its discretion, change the Applicable Discount, the
Compensation, the Per-Participant Limit and any aggregate share purchase limits
previously established with respect to the shortened Purchase Period or Periods.
If the Board shortens any such Purchase Period, the Board shall notify each
Participant in writing that the Exercise Date for his/her purchase right has
been changed to the New Exercise Date and that his/her purchase right will be
exercised automatically on the New Exercise Date, unless prior to such date
he/she has withdrawn from such Purchase Period as provided in paragraph 10.
Such written notice shall also include a description of any changes made to the
Applicable Discount, the Compensation, the Per-Participant Limit and any
aggregate share purchase limits made pursuant to this paragraph 18(b).

       (c) For purposes of paragraph 18(b), the following definitions shall
apply:

       "Acquiring Person" means any Person who or which, together with all
        ----------------                                                  
       Affiliates and Associates of such Person, shall be the Beneficial Owner
       of 20% or more of the Common Stock then outstanding, but shall not
       include the Company, any Subsidiary of the Company or any employee
       benefit plan of the Company or any Subsidiary of the Company, or any
       entity holding Common Stock for or pursuant to the terms of any such
       plan.  Notwithstanding the foregoing, no Person shall become an Acquiring
       Person as the result of an acquisition of Common Stock by the Company
       which, by reducing the number of shares outstanding, increases the
       proportionate number of shares beneficially owned by such Person to 20%
       or more of the Common Stock of the Company then outstanding; provided,
                                                                    -------- 
       however, that if a Person becomes the Beneficial Owner of 20% or more of
       -------                                                                 
       the Common Stock of the Company then outstanding by reason of share
       purchases by the Company and shall, after such share purchases by the
       Company, become the Beneficial Owner of any additional Common Stock of
       the Company, then such Person shall be deemed to be an Acquiring Person.

       "Affiliate" and "Associate" have the respective meanings ascribed to such
        ---------       ---------                                               
       terms in Rule 12b-2 of the General Rules and Regulations under the
       Exchange Act.

            ----------------------------------                               
not be issued with respect to a purchase right unless the exercise of such
purchase right and the issuance and delivery of such shares pursuant thereto
shall comply with all applicable provisions of law, domestic or foreign,
including, without limitation, the Securities Act of 1933, as amended, the
Exchange Act, the rules and regulations promulgated thereunder, and the
requirements of any stock exchange or any automated inter-dealer quotation
system maintained by the National Association of Securities Dealers, Inc. upon
which the Common Stock may then be listed, and shall be further subject to the
approval of counsel for the Company with respect to such compliance.  As a
condition to the exercise of a purchase right, the Company may require the
person exercising such purchase right to represent and warrant at the time of
any such exercise that the shares are being purchased only for investment and
without any present intention to sell or distribute such shares if, in the
opinion of counsel for the Company, such a representation is required by any of
the aforementioned applicable provisions of law.

       22.  Additional Restrictions of Rule 16b-3.  The terms and conditions of
            -------------------------------------

subject to Section 16 of the Exchange Act 

                                      -10-
<PAGE>
 
shall comply with the applicable provisions of Rule 16b-3. This Plan shall be
deemed to contain, such purchase rights shall contain, and the shares issued
upon exercise thereof shall be subject to, such additional conditions and
restrictions as may be required by Rule 16b-3 to qualify for the maximum
exemption from Section 16 of the Exchange Act with respect to Plan transactions.

       23.  Effective Date.  The Plan shall become effective on the date it is
            --------------                                                    
approved by the stockholders (the "Effective Date").

(10) years after the Effective Date unless sooner terminated under paragraph 19.
No rights may be granted under the Plan following its termination.

       25.  Shareholder Approval.  Continuance of the Plan shall be subject to

approval by the shareholders of the Company within twelve (12) months before or
after the date the Plan is adopted by the Board.  If such shareholder approval
is obtained at a duly held shareholders' meeting, the Plan must be approved by a
majority of the votes cast at a shareholders' meeting at which a quorum
(consisting of at least a majority of all outstanding voting stock of the
Company) is, either in person or by proxy, present and voting on the Plan, or,
if such shareholder approval is obtained by written consent, it must be obtained
by the written consent of the holders of a majority of all outstanding voting
stock of the Company; provided, however, that approval at a meeting or by
written consent may be obtained by a lesser degree of shareholder approval if
the Board determines, in its discretion after consultation with the Company's
legal counsel, that such a lesser degree of shareholder approval will comply
with all applicable laws and will not adversely affect the qualification of the
Plan under Section 423 of the Code.

       26.  No Employment Rights.  The Plan does not, directly or indirectly,
            --------------------                                             
create any right for the benefit of any employee or class of employees to
purchase any shares under the Plan, or create in any employee or class of
employees any right with respect to continuation of employment by the Company,
and it shall not be deemed to interfere in any way with the Company's right to
terminate, or otherwise modify, an employee's employment at any time.

       27.  Effect of Plan.  The provisions of the Plan shall, in accordance
            --------------                                                  
with its terms, be binding upon, and inure to the benefit of, all successors of
each Participant, including, without limitation, such Participant's estate and
the executors, administrators or trustees thereof, heirs and legatees, and any
receiver, trustee in bankruptcy or representative of creditors of such
Participant.

       28.  Governing Law.  The law of the State of California will govern all
            -------------                                                     
matters relating to this Plan except to the extent it is superseded by the laws
of the United States.

                               ACUSON CORPORATION

                           1995 STOCK INCENTIVE PLAN
                           -------------------------


1.  Establishment, Purpose, and Definitions.
    --------------------------------------- 

    (a) Acuson Corporation (the "Company") hereby adopts the Acuson Corporation
1995 Stock Incentive Plan (the "Plan").

    (b) The purpose of the Plan is to allow the Company to provide incentives to
Eligible Individuals (as defined in Section 4, below) for employment, increased
efforts and successful achievements on behalf of or in the interests of the
Company and its Affiliates and to maximize the rewards due them for those
efforts and achievements.  In the case of Employees (including officers and
directors who are Employees) of the Company and of its Affiliates such
incentives include (i) an opportunity to purchase shares of common stock, par
value $.0001 per share, of the Company ("Stock") pursuant to options which may
qualify as incentive stock options (referred to as "incentive stock options")
under Section 422 of the Internal Revenue Code of 1986, as amended (the "Code"),
(ii) an opportunity to purchase shares of Stock pursuant to options which are
not described in Sections 422 or 423 of the Code (referred to as "nonqualified
stock options"), (iii) the sale or bonus of restricted Stock ("Restricted
Stock"), and (iv) the grant of stock appreciation rights ("SARs"), either
separately or in relation ("tandem") with stock options, entitling holders to
compensation measured by appreciation in the value of Stock. The Plan also
provides for the grant of similar incentives (other than incentive stock
options) to independent contractors and consultants to the Company and its
Affiliates. Finally, the Plan provides for the automatic, nondiscretionary grant
of nonqualified stock options to directors of the Company who are not Employees
of the Company or any Affiliate ("Non-Employee Directors").

    (c) Except for purposes of Section 12, the term "Affiliate" means parent or
subsidiary corporations of the Company, as defined in Sections 424(e) and (f) of
the Code (but substituting "the Company" for "employer corporation"), including
parents or subsidiaries of the Company that become such after adoption of the
Plan.

    (d) The term "Employee" means any person, including officers and directors,
who is an employee of the Company or an Affiliate for purposes of income tax
withholding under the Code. Neither service as a director nor payment of a
director's fee by the Company shall be sufficient to constitute a person an
Employee.

2.  Administration of the Plan.
    -------------------------- 

    (a) If permitted by Rule 16b-3 (or any successor thereto) promulgated under
the Securities Exchange Act of 1934, as amended ("Rule 16b-3"), the Plan may be
administered by different committees with respect to: (i) Non-Employee
Directors; (ii) Eligible Individuals who are (A) officers or directors subject
to Section 16(b) of the Securities Exchange Act of 1934, as amended (the
"Exchange Act"), or (B) "covered employees" within the meaning of Section
162(m)(3) of the Code ("Covered Employees"); and (iii) Eligible Individuals who
are neither officers or directors subject to Section 16(b) of the Exchange Act
nor Covered Employees.  Each committee, in addition to satisfying any specific
requirements imposed by this Section 2, shall also satisfy any legal
requirements relating to the administration of stock-based compensation plans
under applicable state corporate and securities laws and the Code ("Applicable
Laws"). References herein to the "Plan Administrator" shall refer to the
applicable committee(s) or, if the Board of

                                       1
<PAGE>
 
Directors of the Company (the "Board") does not delegate administration of some
aspects of the Plan to a committee, shall be construed to refer to the Board.

    (b) The Secretary of the Company shall administer the provisions of Section
5 of the Plan (providing for stock option grants to Non-Employee Directors).
This function shall be limited to matters of interpretation and administrative
oversight.

    (c) With respect to awards made to Eligible Individuals who are officers or
directors subject to Section 16(b) of the Exchange Act or Covered Employees, the
Plan shall be administered by a committee of the Board, which committee shall be
constituted to comply with the rules governing a plan intended to qualify as a
discretionary plan under Rule 16b-3 and a "committee comprised solely of two or
more outside directors" for purposes of Section 162(m) of the Code. Once
appointed, such committee shall continue to serve in its designated capacity
until otherwise directed by the Board. From time to time, the Board may increase
the size of the committee and appoint additional members, remove members (with
or without cause) and substitute new members, fill vacancies (however caused),
all to the extent permitted by Rule 16b-3, Section 162(m) of the Code, the rules
and regulations with respect to each, and Applicable Laws.  The committee shall
select one of its members as chair of the committee and shall hold meetings at
such times and places as it may determine.  To the extent permitted by Rule 16b-
3, Section 162(m) of the Code, the rules and regulations with respect to each,
and Applicable Laws, a majority of the committee shall constitute a quorum, and
acts of the committee at which a quorum is present, or acts reduced to or
approved in writing by all the members of the committee, shall be the valid acts
of the committee.

    (d) With respect to awards made to Eligible Individuals who are neither
officers nor directors subject to Section 16(b) of the Exchange Act nor Covered
Employees, the Plan shall be administered by (i) the Board; or (ii) a committee
of one or more persons (which may be the committee established pursuant to
Section 2(c), above) designated by the Board. Once appointed, such committee
shall continue to serve in its designated capacity until otherwise directed by
the Board. From time to time, the Board may increase the size of the committee
and appoint additional members, remove members (with or without cause) and
substitute new members, fill vacancies (however caused), and remove all members
of the committee and thereafter directly administer the Plan, all to the extent
permitted by Applicable Laws. The committee shall select one of its members as
chair of the committee and shall hold meetings at such times and places as it
may determine.  To the extent permitted by Applicable Laws, a majority of the
committee shall constitute a quorum, and acts of the committee at which a quorum
is present, or acts reduced to or approved in writing by all the members of the
committee, shall be the valid acts of the committee.

    (e) The Plan Administrator shall determine which Eligible Individuals shall
be granted options under the Plan, the timing of such grants, the terms thereof
(including any restrictions on the Stock), and the number of shares subject to
such options.

    (f) The Plan Administrator shall also determine which Eligible Individuals
shall be granted or issued SARs or Restricted Stock (other than pursuant to the
exercise of options) under the Plan, the timing of such grants or issuances, the
terms thereof (including any restrictions and the consideration, if any, to be
paid therefor) and the number of shares or SARs to be granted.

    (g) Except for options granted to Non-Employee Directors pursuant to Section
5, the Plan Administrator may amend the terms of any outstanding option or SAR
granted under this Plan, but any amendment that would adversely affect the
holder's rights under an outstanding option or SAR shall not be made without the
holder's written consent.  The Plan Administrator may, with the holder's written
consent, cancel any outstanding option or SAR or accept any outstanding option
or SAR in exchange for a new option or SAR.  The Plan Administrator also may
amend any Restricted Stock purchase agreement or Restricted Stock bonus
agreement relating to sales or bonuses of Restricted Stock under the Plan, but
any

                                       2
<PAGE>
 
amendment that would adversely affect the individual's rights to the Restricted
Stock shall not be made without his or her written consent.

    (h) The Plan Administrator shall have the sole authority, in its absolute
discretion, to adopt, amend, and rescind such rules and regulations as, in its
opinion, may be advisable for the administration of the Plan, to construe and
interpret the Plan, the rules and the regulations, and the instruments
evidencing options, SARs or Restricted Stock granted or issued under the Plan
and to make all other determinations deemed necessary or advisable for the
administration of the Plan.  All decisions, determinations, and interpretations
of the Plan Administrator shall be binding on all participants.  Notwithstanding
the foregoing, the Plan Administrator shall not exercise any discretionary
functions with respect to options granted to Non-Employee Directors pursuant to
Section 5.

3.  Stock Subject to the Plan.
    ------------------------- 

    (a) The maximum aggregate number of shares of Stock available for issuance
under the Plan and during the life of the Plan shall equal 3,500,000 shares,
subject to adjustment from time to time in accordance with this Section 3.  The
Stock subject to the Plan may be unissued shares, treasury shares or shares
purchased by the Company on the open market or otherwise.

    (b) For purposes of the limitation specified in Section 3(a), the following
principles shall apply, provided that no Stock shall be treated as issuable
under the Plan to persons subject to Section 16 of the Exchange Act if otherwise
prohibited from issuance under Rule 16b-3:



         (1) the following transactions, if granted pursuant to this Plan, shall
         count against and decrease the number of shares of Stock that may be
         issued for purposes of Section 3(a): (i) shares of Stock subject to
         outstanding options, outstanding shares of Restricted Stock, and shares
         subject to SARs granted independently of options (based upon a good
         faith estimate by the Company or the Plan Administrator of the maximum
         number of shares for which the SAR may be settled (assuming payment in
         full in shares of Stock), and (ii) in the case of options granted in
         tandem with SARs, the greater of the number of shares of Stock that
         would be counted if one or the other alone was outstanding (determined
         as described in clause (i) above);

         (2) the following shall be added back to the number of shares of Stock
         that may be issued for purposes of Section 3(a): (i) shares of Stock
         with respect to which options, SARs granted independent of options, or
         Restricted Stock awards expire, are cancelled, or otherwise terminate
         without being exercised, converted, or vested, as applicable, and (ii)
         in the case of options granted in tandem with SARs, shares of Stock as
         to which an option has been surrendered in connection with the exercise
         of a tandem SAR, to the extent the number surrendered exceeds the
         number issued upon exercise of the SAR; provided that, in any case, the
                                                 -------------                  
         holder of such awards did not receive any dividends or other benefits
         of ownership with respect to the underlying shares being added back,
         other than voting rights and the accumulation (but not payment) of
         dividends of Stock;

         (3) shares of Stock subject to SARs granted independently of options
         (calculated as provided in clause (1) above) that are exercised and
         paid in cash shall be added back to the number of shares of Stock that
         may be issued for purposes of Section 3(a), provided that the holder of
         such SAR did not receive any dividends or other benefits of ownership,
         other than

         voting rights and the accumulation (but not payment) of dividends,
         relative to the shares of Stock subject to the SARs;

         (4) shares of Stock that are transferred by a holder of an award (or
         withheld by the Company) as full or partial payment to the Company of
         the purchase price of shares of Stock subject to an option or the
         Company's or any Affiliate's tax withholding obligations shall not be
         added back to the number of shares of Stock that may be issued for
         purposes of Section 3(a) and shall not again be subject to awards; and

         (5) if the number of shares of Stock counted against the number of
         shares that may be issued for purposes of Section 3(a) is based upon an
         estimate made by the Company or the Plan Administrator as provided in
         clause (1) above and the actual number of shares of Stock issued
         pursuant to the applicable award is greater or less than the estimated
         number, then upon such issuance, the number of shares of Stock that may
         be issued pursuant to Section 3(a) shall be further reduced by the
         excess issuance or increased by the shortfall, as applicable.


    (c) If there is any change in the Stock through merger, consolidation,
reorganization, recapitalization, reincorporation, stock split, stock dividend
(in excess of 2%), or other change in the capital structure of the Company,
appropriate adjustments shall be made by the Plan Administrator, in order to
preserve but not to increase the benefits to the outstanding options, SARs and
Restricted Stock purchase or Restricted Stock bonus awards under the Plan,
including adjustments to the aggregate number and kind of shares subject to the
Plan, or to outstanding Restricted Stock purchase or Restricted Stock bonus
agreements, or SAR agreements, and the number and kind of shares and the price
per share subject to outstanding options.

    (d) The Plan Administrator shall have the discretion, to the extent
permitted by Applicable Law, to include provisions in any agreements evidencing
awards granted under the Plan providing that, in the event of a dissolution,
liquidation, merger or consolidation of the Company, or any other event that the
Plan Administrator deems to have effected a change in control of the Company,
any such awards shall accelerate and become fully vested, and all forfeiture
and/or transfer restrictions with respect thereto shall lapse, regardless of
whether such awards are otherwise to be assumed or replaced in connection with
such event.

4.  Eligible Individuals.  Individuals who shall be eligible to have the Plan
    --------------------                                                     
Administrator grant to them options, SARs or Restricted Stock under the Plan
("Eligible Individuals") shall be such employees, officers (including officers
who are directors of the Company), independent contractors, and consultants of
the Company or an Affiliate as the Plan Administrator, in its discretion, shall
designate from time to time.  Notwithstanding the foregoing, only Employees
shall be eligible to receive incentive stock options.  Eligible Individuals
shall not include Non-Employee Directors.  Non-Employee Directors shall receive
automatic and nondiscretionary option grants pursuant to Section 5 and will not
be otherwise eligible to receive any other option grants or awards of SARs or
Restricted Stock under the Plan or any other stock plan of the Company or any
Affiliate.

5.  Automatic Option Grants to Non-Employee Directors.
    ------------------------------------------------- 

    (a) All grants of options pursuant to this Section 5 shall be automatic and
nondiscretionary and shall be made strictly in accordance with the provisions of
this Section 5.  No person shall have any discretion to determine which Non-
Employee Directors shall be granted options, the number of shares of Stock to be
covered by options granted to Non-Employee Directors, the timing of such option
grants or the exercise price thereof.

                                       4
<PAGE>
 
    (b) An option to purchase 5,000 shares of Stock shall be granted to each
Non-Employee Director continuing in office immediately following each annual
meeting of the Company's stockholders which occurs on or after the date of
approval of the Plan by the stockholders of the Company and prior to the
termination of the Plan.

    (c) The term of each option granted pursuant to this Section 5 shall be ten
years from the date of grant, unless a shorter period is required to comply with
any Applicable Law, and except for the early termination provisions contained in
the written stock option agreement in the form of Exhibit A hereto, in either of
which cases such shorter period shall apply.

    (d) Each option granted pursuant to this Section 5 shall vest and become
fully exercisable as to fifty percent (50%) of the shares subject to the option
on the date which is six (6) months from the date the option is granted, then
daily thereafter as to 1/365th of the total shares subject to the option so that
the option is fully exercisable no later than one year following the date the
option is granted.

    (e) Each option grant to an Non-Employee Director pursuant to this Section 5
shall be evidenced by a written stock option agreement, in the form of Exhibit A
hereto, executed by the Company and the Non-Employee Director to whom such
option is automatically granted.

    (f) This Section 5 shall be deemed to contain such additional conditions and
restrictions as may be required for the Plan with respect to options granted
pursuant to this Section 5 to qualify as a "formula plan" under Rule 16b-3 as
then applicable to the Company or any Affiliate.

6.  Terms and Conditions of Options.
    ------------------------------- 

    (a) Each option granted pursuant to the Plan will be evidenced by a written
stock option agreement executed by the Company and the person to whom such
option is granted.

    (b) Except for options granted under Section 5 above, the Plan Administrator
shall determine the term of each option granted under the Plan; provided,
however, that the term of an incentive stock option shall not be for more than
ten years and that, in the case of an incentive stock option granted to a person
possessing more than 10% of the combined voting power of the Company or an
Affiliate on the date the option is granted, the term of each incentive stock
option shall be no more than five years.

    (c) In the case of incentive stock options, the aggregate fair market value
(determined as of the time such option is granted) of the Stock with respect to
which incentive stock options are exercisable for the first time by an Eligible
Individual in any calendar year (under this Plan and any other plans of the
Company or its Affiliates) shall not exceed $100,000. If the aggregate fair
market value of the Stock with respect to which incentive stock options are
exercisable by an optionee for the first time in any calendar year exceeds
$100,000, such options shall be treated, to the minimum extent required to
preserve incentive stock option treatment for as many options as possible, as
nonqualified stock options. The rule set forth in the preceding sentence shall
be applied by taking options into account in the order in which they were
granted.

    (d) The exercise price of each incentive stock option shall be not less than
the per share fair market value of the Stock subject to such option on the date
the option is granted.  The exercise price of each nonqualified stock option
shall be as determined by the Plan Administrator.  Notwithstanding the
foregoing, (i) in the case of an incentive stock option granted to a person
possessing more than 10% of the combined voting power of the Company or an
Affiliate on the date the option is granted, the exercise price shall be not
less than 110% of the fair market value of the Stock on the date the option is
granted, and

                                       5
<PAGE>
 
(ii) in the case of an option granted pursuant to Section 5 above, the exercise
price shall be not less than the per share fair market value of the Stock
subject to such option on the date the option is granted. The exercise price of
an option shall be subject to adjustment to the extent provided in Section 3(c),
above.

    (e) Except for options granted under Section 5 above, the stock option
agreement may contain such other terms, provisions, and conditions consistent
with this Plan as may be determined by the Plan Administrator.  If an option, or
any part thereof, is intended to qualify as an incentive stock option, the stock
option agreement shall contain those terms and conditions which are necessary to
so qualify it.

    (f) The maximum number of shares of Stock with respect to which SARs or
options to acquire Stock may be granted to any individual during any calendar
year shall not exceed 1,000,000 shares (which number may be increased without
stockholder approval to reflect adjustments under Section 3(c), above, to the
extent such increase does not cause the grant to fail to qualify as remuneration
payable solely on account of one or more performance goals within the meaning of
Section 162(m) of the Code). To the extent required by Section 162(m) of the
Code or the regulations thereunder, in applying the foregoing limitation with
respect to any employee, if any option is cancelled, the cancelled option shall
continue to count against the maximum number of shares for which options may be
granted to the employee under this Section 6(f). For this purpose, the repricing
of an option shall be treated as a cancellation of the existing option and the
grant of a new option to the extent required by Section 162(m) of the Code or
the regulations thereunder.

7.  Payment Upon Exercise of Options.
    -------------------------------- 

    (a) Payment of the purchase price upon exercise of any option granted under
this Plan shall be made in cash, by optionee's personal check, a certified
check, bank draft, or postal or express money order payable to the order of the
Company in lawful money of the United States (collectively, "Cash
Consideration"); provided, however, that, except for options granted under
Section 5 above, the Plan Administrator, in its sole discretion, may permit an
optionee to pay the option price in whole or in part (i) with shares of Stock
owned by the optionee or with shares of Stock withheld from the shares otherwise
deliverable to the optionee upon exercise of an option; (ii) by delivery on a
form prescribed by the Company of an irrevocable direction to a securities
broker approved by the Company to sell shares of Stock and deliver all or a
portion of the proceeds to the Company in payment for the Stock; (iii) by
delivery of the optionee's promissory note with such recourse, interest,
security, and redemption provisions as the Plan Administrator in its discretion
determines appropriate; or (iv) in any combination of the foregoing.  The
exercise price of any options granted under Section 5 above, shall be paid in
Cash Consideration, the consideration specified in clauses (i) or (ii) of the
preceding sentence or in any combination thereof.  Any Stock used to exercise
options shall be valued at its fair market value on the date of the exercise of
the option.  In addition, the Plan Administrator, in its sole discretion, may
authorize the surrender by an optionee of all or part of an unexercised option
(excluding options granted under Section 5 above) and authorize a payment in
consideration thereof of an amount equal to the difference between the aggregate
fair market value of the Stock subject to such option and the aggregate option
price of such Stock.  In the Plan Administrator's discretion, such payment may
be made in cash, shares of Stock with a fair market value on the date of
surrender equal to the payment amount, or some combination thereof.

    (b) In the event that the exercise price is satisfied by shares withheld
from the shares of Stock otherwise deliverable to the optionee, the Plan
Administrator may issue the optionee an additional option, with terms identical
to the option agreement under which the option was exercised, entitling the
optionee to purchase additional shares of Stock equal to the number of shares so
withheld but at an exercise price equal to the fair market value of the Stock on
the grant date of the new option; provided, however, that no such additional
options may be granted with respect to options granted pursuant to Section 5,
above.

                                       6
<PAGE>
 
8   Terms and Conditions of Restricted Stock Purchases and Bonuses
    --------------------------------------------------------------

    (a) Each sale (other than upon exercise of options) or bonus grant of
Restricted Stock pursuant to the Plan will be evidenced by a written Restricted
Stock purchase or Restricted Stock bonus agreement, as applicable, executed by
the Company and the person to whom such Restricted Stock is sold or granted.

    (b) The Restricted Stock purchase agreement or Restricted Stock bonus
agreement may contain such terms, provisions, and conditions consistent with
this Plan as may be determined by the Plan Administrator, including not by way
of limitation, payment terms, restrictions on transfer, forfeiture provisions,
repurchase provisions, and vesting provisions.

    (c) The Plan Administrator may condition the award or the exercise of any
right under an award under this Section 8 upon the attainment of one or more
preestablished objective performance goals meeting the requirements of Section
162(m) of the Code and the regulations thereunder.

9.  Terms and Conditions of SARs.  The Plan Administrator may, under such terms
    ----------------------------                                               
and conditions as it deems appropriate, authorize the issuance of SARs evidenced
by a written SAR agreement (which, in the case of tandem options, may be part of
the option agreement to which the SAR relates) executed by the Company and the
person to whom the SARs are granted.  The SAR agreement shall specify the term
for the SARs covered thereby and contain such other terms, provisions and
conditions consistent with this Plan as may be determined by the Plan
Administrator.

10. Withholding Taxes.
    ----------------- 

    (a) No Stock shall be granted or sold under the Plan to any Eligible
Individual, and no SAR may be exercised, until the individual has made
arrangements acceptable to the Plan Administrator for the satisfaction of
federal, state, and local income and employment tax withholding obligations,
including without limitation obligations incident to the receipt of Stock under
the Plan, the lapsing of restrictions applicable to such Stock, the failure to
satisfy the conditions for treatment as incentive stock options under applicable
tax law, or the receipt of cash payments.  Upon the exercise of an option or the
lapsing of a restriction on Stock issued under the Plan, the Company (or the
optionee's or stockholder's employer) may withhold from the shares otherwise
deliverable to the optionee upon such exercise, or require the stockholder to
surrender shares of Stock as to which the restriction has lapsed, such number of
shares having a fair market value sufficient to satisfy federal, state and local
income and employment tax withholding obligations.

    (b.) In the event that such tax withholding is satisfied by the Company or
the optionee's employer withholding shares of Stock otherwise deliverable to the
optionee, the Plan Administrator may issue the optionee an additional option,
with terms identical to the option agreement under which the option was
exercised, entitling the optionee to purchase additional shares of Stock equal
to the number of shares so withheld but at an exercise price equal to the fair
market value of the Stock on the grant date of the new option; provided,
however, that no such additional options may be granted with respect to options
granted pursuant to Section 5, above.

11. Assignability.  To the extent required by Rule 16b-3, no option or SAR
    -------------                                                         
granted pursuant to this Plan shall be transferable by the holder except by
operation of law or by will or the laws of descent and distribution; provided
that, if Rule 16b-3 is amended after the date of the Board's adoption of the
Plan to permit broader transferability of options or SARs under that Rule, (i)
options granted under Section 5 to Non-Employee Directors shall be transferable
to the fullest extent permitted by Rule 16b-3 as so amended, (ii) any other
option or SAR shall be transferable to the extent provided in the option
agreement or SAR agreement covering the option or SAR, and the Plan
Administrator shall have the discretion to amend any

                                       7
<PAGE>
 
such outstanding option or SAR to provide for broader transferability of the
option or SAR as the Plan Administrator may authorize within the limitations of
Rule 16b-3. Stock subject to a Restricted Stock purchase agreement or a
Restricted Stock bonus agreement shall be transferable only as provided in such
agreement. Notwithstanding the foregoing, if required by the Code, each
incentive stock option under the Plan shall be transferable by the optionee only
by will or the laws of descent and distribution, and, during the optionee's
lifetime, be exercisable only by the optionee. In the event of any Rule 16b-3
permitted transfer of an option hereunder, the transferee shall be entitled to
exercise the option in the same manner and only to the same extent as the
optionee (or his/her personal representative or the person who would have
acquired the right to exercise the option by bequest or intestate succession)
would have been entitled to exercise the option under Sections 5, 6 and 7 had
the option not been transferred.

12. Change in Control.
    ----------------- 

    (a) Notwithstanding anything to the contrary contained in the Plan, each
stock option, SAR, Restricted Stock bonus or Restricted Stock purchase agreement
(or an amendment thereto) evidencing an option, SAR, Restricted Stock bonus or
Restricted Stock purchase hereunder shall automatically and without further
action be fully vested, nonforfeitable and become exercisable, and any
Restricted Stock covered by such an agreement shall be released from
restrictions on transfer and repurchase or forfeiture rights, on the twenty-
second day after any Share Acquisition Date, unless prior to such twenty-second
day a majority of the Continuing Directors then in office has determined that
the transaction pursuant to which a Person has become an Acquiring Person is an
Approved Transaction.

    (b) Certain Definitions.  For purposes of this Section 12, the following
        -------------------                                                 
definitions shall apply:

         "Acquiring Person" means any Person who or which, together with all
          ----------------                                                  
         Affiliates and Associates of such Person, shall be the Beneficial Owner
         of 20% or more of the Common Shares then outstanding, but shall not
         include the Company, any Subsidiary of the Company or any employee
         benefit plan of the Company or any Subsidiary of the Company, or any
         entity holding Common Shares for or pursuant to the terms of any such
         plan.  Notwithstanding the foregoing, no Person shall become an
         "Acquiring Person" as the result of an acquisition of Common Shares by
         the Company which, by reducing the number of shares outstanding,
         increases the proportionate number of shares beneficially owned by such
         Person to 20% or more of the Common Shares of the Company then
         outstanding; provided, however, that if a Person becomes the Beneficial
                      --------  -------                                         
         Owner of 20% or more of the Common Shares of the Company then
         outstanding by reason of share purchases by the Company and shall,
         after such share purchases by the Company, becomes the Beneficial Owner
         of any additional Common Shares of the Company, then such Person shall
         be deemed to be an "Acquiring Person".

         "Affiliate" and "Associate" have the respective meanings ascribed to
          ---------       ---------

         Exchange Act.

         "Approved Transaction" means any transaction that occurs at a time when

         Continuing Directors are in office and a majority of the Continuing
         Directors then in office has determined that the transaction is in the
         best interest of the Company and its stockholders.

         A Person shall be deemed the "Beneficial Owner" of and shall be deemed
                                       ----------------

         such Person's Affiliates or Associates beneficially owns, directly or
         indirectly; (ii) which such Person or any of such Person's Affiliates
         or Associates has (A) the right to acquire (whether such right is
         exercisable immediately or only after the passage of time) pursuant to
         any agreement, arrangement or

                                       8
<PAGE>
 
         understanding, or upon the exercise of conversion rights, exchange
         rights, rights (other than the Rights), warrants or options, or
         otherwise; provided, however, that a Person shall not be deemed the
                    --------  -------
         Beneficial Owner of, or to beneficially own, securities tendered
         pursuant to a tender or exchange offer made by or on behalf of such
         Person or any of such Person's Affiliates or Associates until such
         tendered securities are accepted for purchase or exchange; or (B) the
         right to vote pursuant to any agreement, arrangement or understanding;
         provided, however, that a Person shall not be deemed the Beneficial
         --------  -------
         Owner of, or to beneficially own, any security if the agreement,
         arrangement or understanding to vote such security (1) arises solely
         from a revocable proxy or consent given to such person in response to a

         accordance with, the applicable rules and regulations of the Exchange
         Act and (2) is not also then reportable on Schedule 13D under the
         Exchange Act (or any comparable or successor report); or (iii) which
         are beneficially owned, directly or indirectly, by any other Person
         with which such Person or any of such Person's Affiliates or Associates
         has any agreement, arrangement or understanding for the purpose of
         acquiring, holding, voting (except to the extent contemplated by the
         proviso to clause (ii)(B) of this definition) or disposing of any
         securities of the Company; provided further, however, that nothing in
         this Section 12 shall cause a Person to be the Beneficial Owner of, or
         to beneficially own, any securities (x) acquired through such Person's
         participation in the business of underwriting securities in good faith
         in a firm commitment underwriting until the expiration of forty days
         after the date of such acquisition or (y) which such Person has
         reported on Schedule 13G under the Exchange Act and has not ceased to

         Exchange Act.

         Person who subsequently becomes a member of the Board, while such
         Person is a member of the Board, who is not an Acquiring Person, or an
         Affiliate or Associate of an Acquiring Person, or a representative of
         an Acquiring Person or of any such Affiliate or Associate, if such

deems advisable; provided that such amendment, suspension or termination
complies with all applicable requirements of state and federal law, including
any applicable requirement that the Plan or an amendment to the Plan be approved

         (3) To materially modify the eligibility requirements for participation
         in the Plan or the class of employees eligible to receive options under
         the Plan or to change the designation or class of persons eligible to
         receive incentive stock options under the Plan.


    (b) No option or SAR may be granted nor may any Stock be issued (other than
upon exercise of outstanding options) under the Plan during any suspension or
after the termination of the Plan, and no amendment, suspension, or termination

any rights or obligations under any option or SAR previously granted under the
Plan.

    (c) In addition to the limitations on amendments provided in Sections 13(a)
and 13(b) above, the provisions set forth in Section 5 of the Plan (and any
other sections of the Plan that affect the formula award terms of option grants

shall not be amended periodically and in no event more than once every six
months, other than to comport with changes in the Code, the Employee Retirement

thereunder.

14. Term of Plan.  The Plan shall terminate with respect to the grant of
    ------------                                                        
additional awards on the tenth anniversary of the date the Plan is approved by
the stockholders, unless previously terminated by the Board pursuant to Section
13.

15. Use of Proceeds.  Cash proceeds realized from the exercise of options
    ---------------                                                      
granted under the Plan or from other sales of Stock under the Plan shall
constitute general funds of the Company.

16. Stockholder Approval.  The Plan shall become effective, and awards may be
    --------------------                                                     
granted hereunder, only upon approval by the holders of a majority of the

award granted pursuant thereto shall confer upon any employee, independent
contractor, consultant or director any right to continue in the employ of the
Company or any Affiliate (or to continue acting as an independent contractor,

                               ACUSON CORPORATION

          NON-EMPLOYEE DIRECTORS' NON-QUALIFIED STOCK OPTION AGREEMENT
          ------------------------------------------------------------


          This agreement (the "Agreement") is made as of __________ __, 199__
(the "Grant Date") between Acuson Corporation (the "Company") and
_________________ ("Optionee").

WITNESSETH:

          WHEREAS, the Company has adopted the Acuson Corporation 1995 Stock
Incentive Plan (the "Plan"), which Plan is incorporated in this Agreement by
reference and made a part of it (capitalized terms shall have the meaning
ascribed to them in the Plan);

          WHEREAS, the Plan provides for automatic option grants to Non-Employee
Directors of the Company;

          NOW, THEREFORE, in consideration of the mutual covenants hereinafter
set forth, the parties to this Agreement hereby agree as follows:



          1.  Option Grant.  The Company hereby grants to Optionee the right and
              ------------                                                      
option to purchase from the Company on the terms and conditions hereinafter set
forth, all or any part of an aggregate of Five Thousand (5,000) shares of the
Common Stock, $.0001 par value, of the Company (the "Stock").  The exercise
price of the Stock subject to this option shall be $_______ per share. This
grant is an automatic option grant under Section 5 of the Plan.

          2.  Option Period.  This option shall be exercisable only during the
              -------------                                                   
period (the "Option Period") commencing on the Grant Date and, except as
provided in paragraph 3, ending on the date (the "Terminal Date") which shall be
ten years from the Grant Date.  During the Option Period, the exercisability of
this option shall be subject to the limitations of paragraph 3 and the vesting
provisions of paragraph 4.


          3.  Limits on Option Period.  The Option Period may end before the
              -----------------------                                       
Terminal Date, as follows:

          (a) If Optionee ceases to be a director on the Company's Board of
Directors (the "Board") for any reason other than cause, disability (within the
meaning of subparagraph (c) below) or death during the Option Period, the Option
Period shall terminate on the earlier of (i) the last day of the period,
beginning on the day next following the day on which the Optionee ceases to be a
director, which equals in length the most recent period of the Optionee's
continuous service as a director (including all portions of such period prior to
the Grant Date), (ii) three years after the date Optionee ceases to be a
director, or (iii) the Terminal Date, and in each case the option shall be
exercisable only to the extent exercisable under paragraph 4 on the date
Optionee ceases to be a director.

          (b) If Optionee should die while serving on the Board, the Option
Period shall terminate three years after the date of death or on the Terminal
Date, whichever shall first occur, and this option shall be exercisable only to
the extent exercisable under paragraph 4 on the date of Optionee's death.  In
the event of Optionee's death, Optionee's executor or administrator or the
person or persons to whom Optionee's rights under this option shall pass by will
or by the applicable laws of descent and distribution 

                                       1
<PAGE>
 
may exercise the entire unexercised portion of this option to the extent
exercisable on the date of Optionee's death.

          (c) If Optionee ceases to be a director by reason of disability, as
defined below, the Option Period shall terminate three years after the date
Optionee ceases to be a director or on the Terminal Date, whichever shall first
occur, and this option shall be exercisable only to the extent exercisable under
paragraph 4 on the date Optionee ceases to be a director.  For purposes of this
subparagraph (c), an individual is permanently and totally disabled if he is
unable to engage in any substantial gainful activity by reason of any medically
determinable physical or mental impairment which can be expected to result in
death or which has lasted or can be expected to last for a continuous period of
not less than 12 months.  An individual shall not be considered to be
permanently and totally disabled unless he furnishes proof of the existence
thereof in such form and manner, and at such times, as the Board may require.

          (d) If Optionee is removed from the Board for cause during the Option
Period, the Option Period shall terminate on the date of such Optionee's removal
as a director and shall not thereafter be exercisable to any extent.

          4.  Vesting of Right to Exercise Options.
              ------------------------------------ 

          (a) This option shall vest as to fifty percent (50%) of the number of
shares originally covered by this option on the date which is six months from
the Grant Date, then daily thereafter as to 1/365th of the total shares subject
to this option so that the option will become fully vested and exercisable no
later than one (1) year following the Grant Date. In no event shall the Company
be required to issue fractional shares.

          (b) Notwithstanding the foregoing, all options granted under this
Agreement shall be fully vested and nonforfeitable and shall become fully
exercisable under the circumstances specified in Section 12 of the Plan.


          5.  Method of Exercise.  Optionee may exercise the option with respect
              ------------------                                                
to all or any part of the shares of Stock then subject to such exercise as
follows:

          (a) By giving the Company written notice of such exercise, specifying
the number of such shares as to which this option is exercised.  Such notice
shall be accompanied by an amount equal to the exercise price of such shares, in
any of the forms permitted under Section 7 of the Plan.

          (b) If required by the Company, Optionee shall give the Company
satisfactory assurance in writing, signed by Optionee or Optionee's legal
representative, as the case may be, that such shares are being purchased for
investment and not with a view to the distribution thereof, provided that such
assurance shall be deemed inapplicable to (1) any sale of such shares by such
Optionee made in accordance with the terms of a registration statement covering
such sale, which has heretofore been (or may hereafter be) filed and become
effective under the Securities Act of 1933, as amended, and with respect to
which no stop order suspending the effectiveness thereof has been issued, and
(2) any other sale of such shares with respect to which, in the opinion of
counsel for the Company, such assurance is not required to be given in order to
comply with the provisions of the Securities Act of 1933, as amended.

          (c) As soon as practicable after receipt of the notice required in
paragraph 5(a) and satisfaction of the conditions set forth in paragraph 5(b),
the Company shall, without transfer or issue tax and without other incidental
expense to Optionee, deliver to Optionee at the office of the Company, at 1220
Charleston Road, Mountain View, CA 94043, attention of the Corporate Secretary,
or such other place as may be mutually acceptable to the Company and Optionee, a
certificate or certificates for such 

                                       2
<PAGE>
 
shares of Stock; provided, however, that the time of such delivery may be
postponed by the Company for such period as may be required for it with
reasonable diligence to comply with applicable registration requirements under
the Securities Act of 1933, as amended, the Securities Exchange Act of 1934, as
amended, any applicable listing requirements of any national securities
exchange, and requirements under any other law or regulation applicable to the
issuance or transfer of such shares. If Optionee fails to accept delivery of and
pay for all or any part of the number of shares specified in such notice upon
tender or delivery thereof, Optionee's right to purchase such shares may be
terminated by the Company at its election.


         6.   Changes in Capitalization.  If there should be any change in a
              -------------------------                                     
class of Stock subject to this option, through merger, consolidation,
reorganization, recapitalization, reincorporation, stock split, stock dividend
(in excess of 2 percent) or other change in the capital structure of the
Company, appropriate adjustments shall be made in order to preserve, but not to
increase, the benefits to Optionee, including adjustments of the number and kind
of shares of such Stock subject to this option and of the price per share. Any
adjustment made pursuant to this paragraph 6 as a consequence of a change in the
capital structure of the Company shall not entitle Optionee to acquire a number
of shares of such Stock of the Company or shares of stock of any successor
company greater than the number of shares Optionee would receive if, prior to
such change, Optionee had actually held a number of shares of such Stock equal
to the number of shares subject to this option.


         7.  Limitations on Transfer.  To the extent required by Rule 16b-3
             -----------------------                                       
under the Exchange Act, this option shall not be transferable by Optionee other
than by operation of law or by will or by the laws of descent or distribution;
provided that, if Rule 16b-3 is amended after the Board's adoption of the Plan
to permit greater transferability, this option shall be transferable to the
fullest extent provided by Rule 16b-3 as so amended.  In the event of any Rule
16b-3 permitted transfer of this option, the transferee shall be entitled to
exercise this option in the same manner and only to the same extent as the
Optionee (or his personal representative or the person who would have acquired
the right to exercise this option by bequest or intestate succession) would have
been entitled to exercise this option had this option not been transferred.

         8.  No Stockholder Rights.  Neither Optionee nor any person entitled
             ---------------------                                           
to exercise Optionee's rights in the event of Optionee's death shall have any of
the rights of a stockholder with respect to the shares of Stock subject to this
option except to the extent the certificates for such shares shall have been
issued upon the exercise of this option.

         9.  No Employment Right.  Nothing in the Plan or this Agreement shall
             -------------------                                              
confer upon the Optionee any right to continue service as a director of the
Company or any Affiliate or shall affect the right of the Company or any
Affiliate or the shareholders of the Company or any Affiliate, as the case may
be to terminate the directorship of Optionee, with or without cause.

         10.  Notice.  Any notice required to be given under the terms of this
              ------                                                          
Agreement shall be addressed to the Company in care of its Corporate Secretary
at the office of the Company at 1220 Charleston Road, Mountain View, CA 94043,
and any notice to be given to Optionee shall be addressed to Optionee at the
address given by Optionee beneath Optionee's signature to this Agreement, or
such other address as either party to this Agreement may hereafter designate in
writing to the other.  Any such notice shall be deemed to have been duly given
when enclosed in a properly sealed envelope addressed as aforesaid, registered
or certified and deposited (postage and registration or certification fee
prepaid) in a post office or branch post office regularly maintained by the
United States.

         11.  Successors.  This Agreement shall be binding upon and inure to
              ----------                                                    
the benefit of any successor or successors of the Company.  Where the context
permits, "Optionee" as used in this Agreement 

                                       3
<PAGE>
 
shall include Optionee's executor, administrator or other legal representative
or the person or persons to whom Optionee's rights pass by will or the
applicable laws of descent and distribution.

         12.  Withholding.  Optionee agrees to make appropriate arrangements
              -----------                                                   
with the Company for satisfaction of any applicable federal, state or local
income tax withholding requirements or social security requirements.

         13.  Applicable Law.  The interpretation, performance, and enforcement
              --------------                                                   
of this Agreement shall be governed by the laws of the State of California.

         IN WITNESS WHEREOF, this Agreement has been executed as of the day and
year first written above.
