                         WELLPOINT HEALTH NETWORKS INC.

                         2000 EMPLOYEE STOCK OPTION PLAN

                                   ARTICLE ONE

                               GENERAL PROVISIONS

1.1  PURPOSE OF THE PLAN

          This WellPoint Health Networks Inc. 2000 Employee Stock Option Plan
("PLAN") is adopted effective February 17, 2000, (the "EFFECTIVE DATe"), to
enable WellPoint Health Networks Inc. (the "COMPANY") to offer stock options to
non-executive officers of the Company or any affiliate.

1.2  ELIGIBILITY

          The following individuals ("ELIGIBLE INDIVIDUALS") are be eligible to
be granted stock options under the Plan: Each employee of the Company or of an
affiliate ("AFFILIATE") of the Company linked to the Company by a 50% or greater
chain of ownership or in which the Company has a significant ownership interest,
directly or indirectly (as determined by the Committee, as defined below) who,
on the date of grant or such date before the grant as the Committee shall
specify for administrative purposes is not an executive officer of the Company.

1.3  ADMINISTRATION OF THE PLAN

          A. COMMITTEE. The Plan will be administered by a committee or
committees appointed by the Board of Directors of the Company (the "BOARD") and
consisting of two or more members of the Board. If no committee is appointed,
the Board will serve as the committee. The term "COMMITTEE," when used in this
Plan, refers to the committee that has been delegated authority with respect to
a matter, or to the Board if no committee has been delegated such authority.
Members of a committee will serve for such term as the Board may determine, and
may be removed by the Board at any time.

          B. AUTHORITY. The Committee has full authority to administer the Plan
within the scope of its delegated responsibilities, including authority to
interpret and construe any relevant provision of the Plan, to adopt rules and
regulations that it deems necessary, to determine which individuals are Eligible
Individuals, to determine which Eligible Individuals shall be granted options
under the Plan, to determine the amount and/or number of shares subject to such
options, and to determine the terms of such an option (which terms need not be
identical). Decisions of a Committee made within the discretion delegated to it
by the Board are final and binding on all persons.

1.4  STOCK SUBJECT TO THE PLAN

<PAGE>

          A. NUMBER OF SHARES. Shares of the Company's Common Stock ("COMMON
STOCK") available for issuance under the Plan will be drawn from the Company's
authorized but unissued shares of Common Stock or from reacquired shares of
Common Stock, including shares purchased by the Company on the open market. The
number of shares of Common Stock that may be issued under the Plan will not
exceed 3,000,000, subject to adjustment in accordance with Paragraph C below.

          B. SHARE COUNTING. In determining whether the number of shares issued
under the Plan exceeds the maximum number set forth in Paragraph 1.4.A., only
the net number of shares actually issued under an option shall count against the
limit. Thus, if any outstanding option under the Plan expires, is terminated, is
cancelled or is forfeited for any reason before the full number of shares
governed by the option grant are issued, those remaining shares will not be
charged against the limit in Paragraph 1.4.A. above and will be available for
subsequent option grants under the Plan. If shares held by an optionee are
delivered to the Company, or are withheld from shares otherwise issuable under
the option, in payment of all or a portion of the exercise price or tax
withholding obligations under the option, only the net number of shares issued
by the Company (i.e., the gross number less the shares delivered or withheld)
shall be counted toward the limit of Paragraph 1.4.A.

          C. ADJUSTMENTS. If any change is made to the Common Stock issuable
under the Plan by reason of any stock split, stock dividend, recapitalization,
combination of shares, exchange of shares or other change affecting the
outstanding Common Stock as a class without receipt of consideration, then the
Committee shall make appropriate adjustments to (i) the maximum number and/or
class of securities issuable under the Plan and (ii) the number and/or class of
securities and price per share in effect under each option outstanding under the
Plan. The purpose of these adjustments will be to preclude the enlargement or
dilution of rights and benefits under the options.

                                   ARTICLE TWO

                                TERMS OF OPTIONS

2.1  TERMS AND CONDITIONS OF OPTIONS

          A. TYPE AND TERM. All options granted under the Plan shall be
non-qualified options not intended to satisfy the requirements for incentive
stock options under Section 422 of the Internal Revenue Code.

          B. PRICE AND EXERCISABILITY. The option price per share and the period
or periods within the term of an option that such option may be exercised will
be fixed by the Committee.

          C. EXERCISE AND PAYMENT. After any option granted under the Plan
becomes exercisable, it may be exercised by notice to the Company at any time
before termination of the option. The option price will be payable in full in
cash or check made payable to the Company or, subject to such limitations as the
Committee may determine, in one or more of the following alternative forms:

<PAGE>

          (1) in shares of Common Stock valued as of the Exercise Date (defined
below) and held by the optionee for the requisite period to avoid a charge to
earnings; or

          (2) through a sale and remittance procedure under which the option
holder delivers in such form as the Committee shall authorize an exercise notice
and irrevocable instructions to a broker to promptly deliver to the Company the
amount of sale proceeds to pay the option price.

For purposes of Subparagraph (2) immediately above, the "EXERCISE DATE" is the
date on which notice, in such form as the Committee shall authorize, of the
exercise of the option is delivered to the Company. In all other cases, the
Exercise Date is the date on which notice and actual payment is received by the
Company.

An option may provide, subject to such restrictions as the Committee may
specify, that, to the extent that the exercise price of an option (or the
Federal, State and local income and employment tax withholding obligations
attributable thereto) is paid in shares of Common Stock (whether delivered to
the Company by the holder or withheld from shares otherwise issuable upon
exercise), the holder will automatically be granted a new option covering the
number of shares so delivered or withheld; the terms of the new option shall
generally be the same as the option so exercised, except that the per share
exercise price of the new option shall be the fair market value of one share of
Common Stock on the date of grant of the new option and the term of the new
option shall be equal to the remaining term of the option so exercised.

          D. STOCKHOLDER RIGHTS. An option holder will have no stockholder
rights with respect to any shares covered by an option before the Exercise Date
of the option, as defined in the immediately preceding Paragraph.

          E. SEPARATION FROM SERVICE. The Committee will determine and set forth
in each option whether the option will continue to be exercisable, and the terms
of such exercise, on and after the date that an optionee ceases to be employed
by or to provide services to the Company or an Affiliate. The date of
termination of an optionee's employment or services will be determined by the
Committee, which determination will be final.

          F. TRANSFERABILITY. During the lifetime of the optionee, options will
be exercisable only by the optionee and will not be assignable or transferable
by the optionee otherwise than by will or by the laws of descent and
distribution following the optionee's death. However, if and to the extent that
the Committee so authorizes at the time an option is granted or amended, an
option may be assigned in whole or in part during the optionee's lifetime to one
or more members of the optionee's family or an entity in which the optionee or a
member of the optionee's family holds an interest.

2.2  CORPORATE TRANSACTIONS

          The Committee may determine and set forth in each option, either at
the time of grant or by amendment thereafter, the effect, if any, that any sale
of stock or assets, merger, combination, spinoff, reorganization, or liquidation
of the Company will have upon the term, exercisability and/or vesting of
outstanding options, provided that any options that are continued, assumed or
replaced with comparable awards in connection with any transaction will be
adjusted

<PAGE>

as provided in Section 1.4.C. The grant of options under this Plan will in no
way affect the right of the issuer of Common Stock to adjust, reclassify,
reorganize, or otherwise change its capital or business structure or to merge,
consolidate, dissolve, liquidate or sell or transfer all or any part of its
business or assets.

                                  ARTICLE THREE

                                  MISCELLANEOUS

3.1  AMENDMENT

          A. BOARD ACTION. The Board may amend, suspend or discontinue the Plan
in whole or in part at any time; provided, however, that (1) such action shall
not adversely affect a holder's rights and obligations with respect to options
at the time outstanding under the Plan and (2) the Board may condition any
amendment upon the approval of the Company's stockholders, if and to the extent
that the Board determines that stockholder approval is required by applicable
law or regulatory standards or is otherwise advisable.

          B. MODIFICATION OF OPTIONS. The Committee has full power and authority
to modify or waive any or all of the terms, conditions or restrictions
applicable to any outstanding option under the Plan, to the extent not
inconsistent with the Plan; provided, however, that no such modification or
waiver shall, without the consent of the holder of the option, adversely affect
the holder's rights thereunder.

3.2  TAX WITHHOLDING

          A. OBLIGATION. The Company's obligation to deliver shares or
cash upon the exercise of options under the Plan is subject to the satisfaction
of all applicable Federal, State and local income and employment tax withholding
requirements.

          B. STOCK WITHHOLDING. The Committee may require or permit, in
its discretion and upon such terms and conditions as it may deem appropriate,
any or all holders of outstanding options under the Plan to elect to have the
Company withhold, from the shares of Common Stock otherwise issuable pursuant to
such option, one or more of such shares with an aggregate Fair Market Value
equal to the Federal, State and local income and employment taxes ("TAXES")
incurred in connection with the acquisition of such shares. Holders of options
under the Plan may also be granted the right to deliver previously acquired
shares of Common Stock held for the requisite period to avoid a charge to
earnings in satisfaction of such Taxes. The withheld or delivered shares will be
valued at Fair Market Value on the applicable determination date for such Taxes.

3.3  VALUATION

          For all purposes under this Plan, the fair market value per share of
Common Stock on any relevant date under the Plan ("FAIR MARKET VALUE") will be
determined as follows:

          (1) NATIONAL EXCHANGE. If the Common Stock is at the time listed or
admitted to trading on any national stock exchange, then the Fair Market Value
will be the closing selling price per share of Common Stock on the day before
the date in question on the stock exchange

<PAGE>

determined by the Committee to be the primary market for the Common Stock, as
such price is officially quoted in the composite tape of transactions on such
exchange. If there is no reported sale of Common Stock on such exchange on the
day before the date in question, then the Fair Market Value will be the closing
selling price on the exchange on the last preceding date for which such
quotation exists.

          (2) NASDAQ. If the Common Stock is not at the time listed or admitted
to trading on any national stock exchange but is traded in the over-the-counter
market, the fair market value will be the mean between the highest bid and
lowest asked prices (or, if such information is available, the closing selling
price) per share of Common Stock on the date in question in the over-the-counter
market, as such prices are reported by the National Association of Securities
Dealers through its NASDAQ system or any successor system. If there are no
reported bid and asked prices (or closing selling price) for the Common Stock on
the date in question, then the mean between the highest bid price and lowest
asked price (or the closing selling price) on the last preceding date for which
such quotations exist will be determinative of fair market value.

          (3) COMMITTEE. Notwithstanding the foregoing, if the Committee
determines that, as a result of circumstances existing on any date, the use of
the above rules is not a reasonable method of determining Fair Market Value on
that date or if Common Stock is not at the time listed or admitted to trading as
outlined above, the Committee may use such other method as, in its judgment, is
reasonable.

3.4  EFFECTIVE DATE AND TERM OF PLAN

          A. EFFECTIVE DATE. This Plan becomes effective on the Effective Date.

          B. TERM. The Committee may grant options under the Plan at any time
after the Effective Date of the Plan and before the Plan is terminated by the
Board.

3.5  REGULATORY APPROVALS

          The implementation of the Plan, any option grants under the
Plan, and the issuance of stock pursuant to any option granted under the Plan is
subject to the procurement by the Company of all approvals and permits required
by regulatory authorities having jurisdiction over the Plan, option grants made
under the Plan, and stock issued pursuant to the Plan.

3.6  NO EMPLOYMENT/SERVICE RIGHTS

          Neither the establishment of this Plan, nor any action taken under the
terms of this Plan, nor any provision of this Plan will be construed to grant
any individual the right to remain in the employ or service of the Company (or
any subsidiary or parent of the Company) for any period of specific duration,
and the Company (or any subsidiary or parent of the Company

<PAGE>

retaining the services of such individual) may terminate such individual's
employment or service at any time and for any reason, with or without cause;
provided that nothing contained in this Plan or in any option granted under this
Plan will affect any contractual rights of the Company or an employee pursuant
to a written employment agreement executed by the parties thereto.<PAGE>

                             ULTRATECH STEPPER, INC.
                      1993 STOCK OPTION/STOCK ISSUANCE PLAN
                      -------------------------------------
                  (Amended and Restated as of January 3, 2000)

                                   ARTICLE ONE

         I.       PURPOSE OF THE PLAN

         This 1993 Stock Option/Stock Issuance Plan ("Plan") is intended to
promote the interests of Ultratech Stepper, Inc., a Delaware corporation (the
"Corporation"), by providing (i) key employees (including officers) of the
Corporation (or its parent or subsidiary corporations) who are responsible for
the management, growth and financial success of the Corporation (or its parent
or subsidiary corporations), (ii) the non-employee members of the Corporation's
Board of Directors and (iii) independent consultants and other advisors who
provide valuable services to the Corporation (or its parent or subsidiary
corporations) with the opportunity to acquire a proprietary interest, or
otherwise increase their proprietary interest, in the Corporation as an
incentive for them to remain in the service of the Corporation (or its parent or
subsidiary corporations).

         A. The Plan became effective on September 29, 1993, the date on which
the shares of the Corporation's Common Stock were registered under Section 12(g)
of the Securities Exchange Act of 1934, as amended (the "1934 Act"). Such date
is hereby designated as the Effective Date for the Plan.

         B. This Plan shall serve as the successor to the Corporation's existing
1993 Stock Option and 1993 Stock Issuance Plans (the "Predecessor Plans"), and
no further option grants or share issuances shall be made under the Predecessor
Plans from and after the Effective Date of this Plan. All outstanding stock
options and unvested share issuances under the Predecessor Plans on the
Effective Date are hereby incorporated into this Plan and shall accordingly be
treated as outstanding stock options and unvested share issuances under this
Plan. However, each outstanding option grant and unvested share issuance so
incorporated shall continue to be governed solely by the express terms and
conditions of the instrument evidencing such grant or issuance, and no provision
of this Plan shall be deemed to affect or otherwise modify the rights or
obligations of the holders of such incorporated options with respect to their
acquisition of shares of Common Stock thereunder. All unvested shares of Common
Stock outstanding under the Predecessor Plans on the Effective Date shall
continue to be governed solely by the express terms and conditions of the
instruments evidencing such issuances, and no provision of this Plan shall be
deemed to affect or modify the rights or obligations of the holders of such
unvested shares.

         II. DEFINITIONS

         III.     STRUCTURE OF THE PLAN

         A. STOCK PROGRAMS. The Plan shall be divided into three separate
components: the Discretionary Option Grant Program specified in Article Two, the
Automatic Option Grant Program specified in Article Three and the Stock Issuance
Program specified in Article Four. Under the Discretionary Option Grant Program,
eligible individuals may, at the discretion of the Plan Administrator, be
granted options to purchase shares of Common Stock in accordance with the
provisions of Article Two. Under the Automatic Option Grant Program,
non-employee Board members will receive a series of automatic option grants over
their period of continued Board service to purchase shares of Common Stock in
accordance with the provisions of Article Three. Under the Stock Issuance
Program, eligible individuals may be issued shares of Common Stock directly,
either through the immediate purchase of such shares at Fair Market Value at the
time of issuance or as a bonus tied to the performance of services or the
Corporation's attainment of financial objectives, without any cash payment
required of the recipient.

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

         IV.      ADMINISTRATION OF THE PLAN

         A. Both the Discretionary Option Grant Program and the Stock Issuance
Program shall be administered by a committee ("Committee") of two or more
non-employee Board members. Members of the Committee shall serve for such period
of time as the Board may determine and shall be subject to removal by the Board
at any time.

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

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

         V.       OPTION GRANTS AND STOCK ISSUANCES

         A. The persons eligible to participate in the Discretionary Option
Grant Program under Article Two or the Stock Issuance Program under Article Four
shall be limited to the following:
<PAGE>
            1. officers and other key employees of the Corporation (or its
parent or subsidiary corporations) who render services which contribute to
the management, growth and financial success of the Corporation (or its
parent or subsidiary corporations);

            2. non-employee members of the Board; and

            3. those independent consultants or other advisors who provide
valuable services to the Corporation (or its parent or subsidiary
corporations).

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

         VI.      STOCK SUBJECT TO THE PLAN

         A. Shares of Common Stock shall be available for issuance under the
Plan and shall be drawn from either the Corporation's authorized but unissued
shares of Common Stock or from reacquired shares of Common Stock, including
shares repurchased by the Corporation on the open market. The maximum number
of shares of Common Stock reserved for issuance over the term of the Plan
shall be limited to 6,126,229 shares(1). Such share reserve includes (i) the
initial number of shares incorporated into this Plan from the Predecessor
Plans on the Effective Date, (ii) an additional 600,000-share increase
authorized by the Board on March 21, 1996 and approved by the stockholders at
the 1996 Annual Stockholders Meeting, (iii) an additional 277,239 shares
attributable to the automatic annual share increase for fiscal 1996 which was
effected on January 2, 1996, (iv) an additional 284,346 shares attributable
to the automatic annual share increase for fiscal 1997 which was effected on
January 2, 1997, (v) an additional 450,000 shares authorized by the Board on
March 18, 1997 and approved by the stockholders at the 1997 Annual Meeting,
(vi) an additional 291,008 shares attributable to the automatic annual share
increase for fiscal 1998 which was effected on January 2, 1998, (vii) an
additional 295,480 shares attributable to the automatic annual share increase
for fiscal 1999 which was effected on January 4, 1999, and (viii) an
additional 299,490 shares attributable to the automatic annual share increase
for fiscal 2000 which was effected on January 3, 2000. The share reserve in
effect from time to time under the Plan shall be subject to periodic
adjustment in accordance with the provisions of this Section VI. To the
extent one or more outstanding options under the Predecessor Plans which have
been incorporated into this Plan are subsequently exercised, the number of
shares issued with respect to each such option shall reduce, on a
share-for-share basis, the number of shares available for issuance under this
Plan.

         B. In no event may the aggregate number of shares of Common Stock for
which any one individual participating in the Plan may be granted stock options,
separately-exercisable stock appreciation rights and direct stock issuances
exceed 400,000 shares per fiscal year, beginning with the 1995 fiscal year.
However, for the fiscal year in which an individual receives his or her initial
stock option grant or direct stock issuance under the Plan, the limit shall be
increased to 600,000 shares. Such limitations shall be subject to adjustment
from time to time in accordance with the provisions of this Section VI.

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

         D. Should any change be made to the Common Stock issuable under the
Plan by reason of any stock split, stock dividend, recapitalization, combination
of shares, exchange of shares or other change affecting the outstanding Common
Stock as a class without the Corporation's receipt of consideration, then
appropriate adjustments shall be made to (i) the maximum number and/or class of
securities issuable under the Plan, (ii) the maximum number and/or class of
securities for which any one person may be granted stock options, separately
exercisable stock appreciations rights and direct stock issuances under this
Plan per calendar year, (iii) the number and/or class of securities for which
automatic option grants are to be subsequently made per eligible non-employee
Board member under the Automatic Option Grant Program, (iv) the number and/or
class of securities and price per share in effect under each option outstanding
under either the Discretionary Option Grant or Automatic Option Grant Program
and (v) the number and/or class of securities and price per share in effect
under each outstanding option incorporated into this Plan from the Predecessor
Plans. Such adjustments to the outstanding options are to be effected in a
manner which shall preclude the enlargement or dilution of rights and benefits
under such options. The adjustments deter-mined by the Plan Administrator shall
be final, binding and conclusive.

(1)     All figures have been adjusted to reflect the 2:1 stock split the
Corporation effected May 10, 1995.

                                   ARTICLE TWO

                       DISCRETIONARY OPTION GRANT PROGRAM

         I.       TERMS AND CONDITIONS OF OPTIONS

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

         A.       OPTION PRICE.

               1. The option price per share shall be fixed by the Plan
Administrator and shall in no event be less than one hundred percent (100%) of
the fair market value of such Common Stock on the grant date.

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

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

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

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

                           - full payment through a broker-dealer sale and
         remittance procedure pursuant to which the Optionee (I) shall provide
         irrevocable written instructions to a Corporation-designated brokerage
         firm to effect the immediate sale of the purchased shares and remit to
         the Corporation, out of the sale proceeds available on the settlement
<PAGE>
         date, sufficient funds to cover the aggregate option price payable for
         the purchased shares plus all applicable Federal and State income and
         employment taxes required to be withheld by the Corporation in
         connection with such purchase and (II) shall provide written directives
         to the Corporation to deliver the certificates for the purchased shares
         directly to such brokerage firm in order to complete the sale
         transaction.

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

         B. TERM AND EXERCISE OF OPTIONS. Each option granted under this
Discretionary Option Grant Program shall be exercisable at such time or times
and during such period as is determined by the Plan Administrator and set forth
in the instrument evidencing the grant. No such option, however, shall have a
maximum term in excess of ten (10) years from the grant date.

         C. LIMITED TRANSFERABILITY. During the lifetime of the Optionee,
Incentive Options shall be exercisable only by the Optionee and shall not be
assignable or transferable other than by will or by the laws of descent and
distribution following the Optionee's death. However, non-statutory options may,
in connection with the Optionee's estate plan, be assigned in whole or in part
during the Optionee's lifetime to one or more members of the Optionee's
immediate family or to a trust established exclusively for one or more such
family members. The assigned portion may only be exercised by the person or
persons who acquire a proprietary interest in the option pursuant to the
assignment. The terms applicable to the assigned portion shall be the same as
those in effect for the option immediately prior to such assignment and shall be
set forth in such documents issued to the assignee as the Plan Administrator may
deem appropriate.

         D. TERMINATION OF SERVICE.

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

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

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

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

                           - During the applicable post-Service exercise period,
         the option may not be exercised in the aggregate for more than the
         number of shares (if any) in which the Optionee is vested at the time
         of his or her cessation of Service. Upon the expiration of the limited
         post-Service exercise period or (if earlier) upon the specified
         expiration date of the option term, each such option shall terminate
         and cease to be outstanding with respect to any vested shares for which
         the option has not otherwise been exercised. However, each outstanding
         option shall, immediately upon the Optionee's cessation of Service for
         any reason, terminate and cease to be outstanding with respect to any
         shares for which the option is not otherwise at that time exercisable
         or in which the Optionee is not otherwise at that time vested.
<PAGE>
                           - Should (i) the Optionee's Service be terminated for
         misconduct (including, but not limited to, any act of dishonesty,
         willful misconduct, fraud or embezzlement) or (ii) the Optionee make
         any unauthorized use or disclosure of confidential information or trade
         secrets of the Corporation or its parent or subsidiary corporations,
         then in any such event all outstanding options held by the Optionee
         under this Article Two shall terminate immediately and cease to be
         outstanding.

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

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

         E. STOCKHOLDER RIGHTS.

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

         F. REPURCHASE RIGHTS.

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

               (a) The Plan Administrator shall have the discretion to authorize
the issuance of unvested shares of Common Stock under this Article Two. Should
the Optionee cease Service while holding such unvested shares, the Corporation
shall have the right to repurchase any or all of those unvested shares at the
option price paid per share. The terms and conditions upon which such repurchase
right shall be exercisable (including the period and procedure for exercise and
the appropriate vesting schedule for the purchased shares) shall be established
by the Plan Administrator and set forth in the instrument evidencing such
repurchase right.

               (b) All of the Corporation's outstanding repurchase rights under
this Article Two shall automatically terminate, and all shares subject to such
terminated rights shall immediately vest in full, upon the occurrence of a
Corporate Transaction, except to the extent: (i) any such repurchase right is
expressly assigned to the successor corporation (or parent thereof) in
connection with the Corporate Transaction or (ii) such accelerated vesting is
precluded by other limitations imposed by the Plan Administrator at the time the
repurchase right is issued.

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

         II.      INCENTIVE OPTIONS

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

               I. DOLLAR LIMITATION. The aggregate fair market value (determined
as of the respective date or dates of grant) of the Common Stock for which one
or more options granted to any Employee after December 31, 1986 under this Plan
(or any other option plan of the Corporation or its parent or subsidiary
corporations) may for the first time become exercisable as incentive stock
<PAGE>
options under the Federal tax laws during any one calendar year shall not exceed
the sum of One Hundred Thousand Dollars ($100,000). To the extent the Employee
holds two (2) or more such options which become exercisable for the first time
in the same calendar year, the foregoing limitation on the exercisability of
such options as incentive stock options under the Federal tax laws shall be
applied on the basis of the order in which such options are granted. Should the
number of shares of Common Stock for which any Incentive Option first becomes
exercisable in any calendar year exceed the applicable One Hundred Thousand
Dollar ($100,000) limitation, then that option may nevertheless be exercised in
that calendar year for the excess number of shares as a non-statutory option
under the Federal tax laws.

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

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

         III.     CORPORATE TRANSACTIONS/CHANGES IN CONTROL

               A. In the event of any Corporate Transaction, each option which
is at the time outstanding under this Article Two shall automatically accelerate
so that each such option shall, immediately prior to the specified effective
date for the Corporate Transaction, become fully exercisable with respect to the
total number of shares of Common Stock at the time subject to such option and
may be exercised for all or any portion of such shares as fully-vested shares.
However, an outstanding option under this Article Two shall not so accelerate if
and to the extent: (i) such option is, in connection with the Corporate
Transaction, either to be assumed by the successor corporation or parent thereof
or to be replaced with a comparable option to purchase shares of the capital
stock of the successor corporation or parent thereof, (ii) such option is to be
replaced with a cash incentive program of the successor corporation which
preserves the option spread existing at the time of the Corporate Transaction
and provides for subsequent payout in accordance with the same vesting schedule
applicable to such option, or (iii) the acceleration of such option is subject
to other limitations imposed by the Plan Administrator at the time of the option
grant. The determination of option comparability under clause (i) above shall be
made by the Plan Administrator, and its determination shall be final, binding
and conclusive.

               B. Immediately following the consummation of the Corporate
Transaction, all outstanding options under this Article Two shall terminate and
cease to be outstanding, except to the extent assumed by the successor
corporation or its parent company.

               C. Each outstanding option under this Article Two which is
assumed in connection with the Corporate Transaction or is otherwise to continue
in effect shall be appropriately adjusted, immediately after such Corporate
Transaction, to apply and pertain to the number and class of securities which
would have been issued to the option holder, in consummation of such Corporate
Transaction, had such person exercised the option immediately prior to such
Corporate Transaction. Appropriate adjustments shall also be made to the option
price payable per share, PROVIDED the aggregate option price payable for such
securities shall remain the same. In addition, appropriate adjustments to
reflect the Corporate Transaction shall be made to (i) the class and number of
securities available for issuance over the remaining term of the Plan, (ii) the
maximum number and/or class of securities for which any one person may be
granted stock options, separately exercisable stock appreciation rights and
direct stock issuances under this Plan per calendar year and (iii) the maximum
number and/or class of securities which may be issued pursuant to Incentive
Options granted under the Plan.

               D. The Plan Administrator shall have the discretion, exercisable
either at the time the option is granted or at any time while the option remains
outstanding, to provide (upon such terms as it may deem appropriate) for the
automatic acceleration of one or more outstanding options which are assumed or
replaced in the Corporate Transaction and do not otherwise accelerate at that
time, in the event the Optionee's Service should subsequently terminate within a
designated period following the effective date of such Corporate Transaction.
<PAGE>
               E. The grant of options under this Article Two shall in no way
affect the right of the Corporation to adjust, reclassify, reorganize or
otherwise change its capital or business structure or to merge, consolidate,
dissolve, liquidate or sell or transfer all or any part of its business or
assets.

               F. The Plan Administrator shall have the discretionary authority,
exercisable either at the time the option is granted or at any time while the
option remains outstanding, to provide for the automatic acceleration of one or
more outstanding options under this Article Two (and the termination of one or
more of the Corporation's outstanding repurchase rights under this Article Two)
upon the occurrence of any Change in Control. The Plan Administrator shall also
have full power and authority to condition any such option acceleration (and the
termination of any outstanding repurchase rights) upon the subsequent
termination of the Optionee's Service within a specified period following the
Change in Control.

               G. Any options accelerated in connection with the Change in
Control shall remain fully exercisable until the expiration or sooner
termination of the option term.

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

         IV.      CANCELLATION AND REGRANT OF OPTIONS

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

         V.       STOCK APPRECIATION RIGHTS

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

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

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

               D. One or more officers of the Corporation subject to the
short-swing profit restrictions of the Federal securities laws may, in the Plan
Administrator's sole discretion, be granted limited stock appreciation rights in
tandem with their outstanding options under the Plan. Upon the occurrence of a
Hostile Take-Over effected at any time when the Corporation's outstanding Common
Stock is registered under Section 12(g) of the 1934 Act, the officer shall have
a thirty (30)-day period in which he or she may surrender any outstanding option
with such a limited stock appreciation right to the Corporation, to the extent
such option is at the time exercisable for fully-vested shares of Common Stock.
The officer shall in return be entitled to a cash distribution from the
Corporation in an amount equal to the excess of (i) the Take-Over Price of the
vested shares of Common Stock at the time subject to each surrendered option (or
<PAGE>
surrendered portion of such option) over (ii) the aggregate exercise price
payable for such shares. The cash distribution payable upon such option
surrender shall be made within five (5) days following the consummation of the
Hostile Take-Over. The Plan Administrator shall pre-approve, at the time the
limited stock appreciation right is granted, the subsequent exercise of that
right in accordance with the terms of the grant and the provisions of this
Section V.D. No additional approval of the Plan Administrator or the Board shall
be required at the time of the actual option surrender and distribution. Any
unsurrendered portion of the option shall continue to remain outstanding and
become exercisable in accordance with the terms of the instrument evidencing
such grant.

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

                         AUTOMATIC OPTION GRANT PROGRAM
                         ------------------------------

         I.       ELIGIBILITY

                  The provisions of the Automatic Option Grant Program were
revised, effective March 1, 1996, to eliminate the special one-time option grant
for 28,800 shares of Common Stock to each newly-elected or newly-appointed
non-employee Board member and to implement a new program of periodic option
grants to all eligible non-employee Board members. Under the revised Automatic
Option Grant Program, the following individuals shall be eligible to receive
automatic option grants over their period of Board service: (i) those
individuals who were serving as non-employee Board members on the date of the
1996 Annual Stockholders Meeting but who first joined the Board after September
29, 1993, (ii) those individuals who first join the Board as non-employee Board
members after the date of the 1996 Annual Stockholders Meeting and (iii) those
individuals who first joined the Board prior to September 30, 1993 and continue
to serve as non-employee Board members through one or more Annual Stockholders
Meetings, beginning with the 1996 Annual Meeting. However, a non-employee Board
member who has previously been in the employ of the Corporation (or any Parent
or Subsidiary) shall not be eligible to receive a 12,000-share option grant at
the time of his or her initial election or appointment to the Board, but such
individual shall be eligible to receive one or more 4,000-share annual option
grants over his or her period of continued Board service. Each non-employee
Board member eligible to participate in the Automatic Option Grant Program
pursuant to the foregoing criteria shall be designated an Eligible Director for
purposes of the Plan.

         II.      TERMS AND CONDITIONS OF AUTOMATIC OPTION GRANTS

               A. GRANT DATE.

                  1. Each individual serving as a non-employee Board member on
the date of the 1996 Annual Stockholders Meeting shall be granted on that date a
non-statutory stock option to purchase 12,000 shares of Common Stock upon the
terms and conditions of this Article Three, provided such individual (i) has not
previously been in the employ of the Corporation (or any Parent or Subsidiary)
and (ii) did not join the Board prior to September 30, 1993. If any such
individual previously received an automatic option grant for 28,800 shares of
Common Stock at the time of his or her initial election or appointment to the
Board, then that option was automatically cancelled upon stockholder approval of
the revised Automatic Option Grant Program at the 1996 Annual Meeting.

                  2. Each individual who is first elected or appointed as a
non-employee Board member after the date of the 1996 Annual Stockholders Meeting
shall automatically be granted, on the date of such initial election or
appointment, a non-statutory stock option to purchase 12,000 shares of Common
Stock upon the terms and conditions of this Article Three, provided such
individual has not previously been in the employ of the Corporation (or any
Parent or Subsidiary).

                  3. On the date of each Annual Stockholders Meeting, beginning
with the 1996 Annual Stockholders Meeting, each individual who is to continue to
serve as a non-employee Board member, whether or not he or she is standing for
re-election to the Board at that particular Annual Meeting, shall automatically
be granted a Non-Statutory Option to purchase 4,000 shares of Common Stock,
provided such individual did not receive any other option grants under this
Automatic Option Grant Program within the preceding six (6) months. There shall
be no limit on the number of such 4,000-share option grants any one Eligible
Director may receive over his or her period of Board service, and individuals
who have previously been in the employ of the Corporation (or any Parent or
Subsidiary) shall be eligible to receive such annual option grants over their
<PAGE>
period of continued Board service.

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

               C. PAYMENT.

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

                           (i) full payment in cash or check made payable to the
Corporation's order; or

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

                         (iii) full payment in a combination of shares of
Common Stock held for the requisite period necessary to avoid a charge to the
Corporation's reported earnings and valued at Fair Market Value on the Exercise
Date and cash or check payable to the Corporation's order; or

                          (iv) to the extent the option is exercised for vested
shares, full payment through a sale and remittance procedure pursuant to which
the non-employee Board member (I) shall provide irrevocable written instructions
to a Corporation-designated brokerage firm to effect the immediate sale of the
purchased shares and remit to the Corporation, out of the sale proceeds
available on the settlement date, sufficient funds to cover the aggregate
exercise price payable for the purchased shares and shall (II) concurrently
provide written directives to the Corporation to deliver the certificates for
the purchased shares directly to such brokerage firm in order to complete the
sale transaction.

For purposes of this subparagraph C, the Exercise Date shall be the date on
which written notice of the option exercise is delivered to the Corporation.
Except to the extent the sale and remittance procedure specified above is
utilized in connection with the exercise of the option for vested shares,
payment of the option price for the purchased shares must accompany the exercise
notice. However, if the option is exercised for any unvested shares, then the
optionee must also execute and deliver to the Corporation a stock purchase
agreement for those unvested shares which provides the Corporation with the
right to repurchase, at the exercise price paid per share, any unvested shares
held by the optionee at the time of cessation of Board service and which
precludes the sale, transfer or other disposition of any shares purchased under
the option, to the extent those shares are subject to the Corporation's
repurchase right.

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

               E. EXERCISABILITY/VESTING. Each automatic grant shall be
immediately exercisable for any or all of the option shares. However, any shares
purchased under the option shall be subject to repurchase by the Corporation, at
the exercise price paid per share, upon the Optionee's cessation of Board
service prior to vesting in those shares. The shares subject to each
12,000-share initial automatic option grant shall vest as follows: (i) fifty
percent (50%) of the shares shall vest upon the optionee's completion of one (1)
year of Board service measured from the grant date, and (ii) the remaining
shares shall vest in three (3) successive equal annual installments upon the
optionee's completion of each of the next three (3) years of Board service
thereafter. The shares subject to each 4,000-share annual automatic option grant
shall vest upon the optionee's completion of one (1) year of Board service
measured from the grant date. Vesting of the option shares shall be subject to
acceleration as provided in Section II.G and Section III of this Article Three.

               F. LIMITED TRANSFERABILITY. Each option granted under this
Automatic Option Grant Program prior to the 1997 Annual Stockholders Meeting
shall, during the lifetime of the optionee, be exercisable only by the optionee
and shall not be assignable or transferable by the optionee otherwise than by
will or the by the laws of descent and distribution following the optionee's
death. However, each option granted under this Automatic Option Grant Program on
or after the 1997 Annual Stockholders Meeting shall be assignable in whole or in
part by the optionee during his or her lifetime, but only to the extent such
<PAGE>
assignment is made in connection with the optionee's estate plan to one or more
members of the optionee's immediate family or to a trust established exclusively
for one or more such family members. The assigned portion may only be exercised
by the person or persons who acquire a proprietary interest in the option
pursuant to the assignment. The terms applicable to the assigned portion shall
be the same as those in effect for the option immediately prior to such
assignment and shall be set forth in such documents issued to the assignee as
the Plan Administrator may deem appropriate.

               G. EFFECT OF TERMINATION OF BOARD SERVICE.

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

                  2. Should the Optionee die within six (6) months after
cessation of Board service, then any automatic option grant held by the Optionee
at the time of death may subsequently be exercised, for any or all of the option
shares in which the Optionee is vested at the time of his or her cessation of
Board service (less any vested option shares subsequently purchased by the
Optionee prior to death), by the personal representative of the Optionee's
estate or by the person or persons to whom the option is transferred pursuant to
the Optionee's will or in accordance with the laws of descent and distribution.
Any such exercise must occur within twelve (12) months after the date of the
Optionee's death.

                  3. Should the Optionee die or become Permanent Disabled while
serving as a Board member, then the shares of Common Stock at the time subject
to each automatic option grant held by such Optionee under this Article Three
shall immediately vest in full, and the Optionee (or the representative of the
Optionee's estate or the person or persons to whom the option is transferred
upon the Optionee's death) shall have a twelve (12)-month period following the
date of the Optionee's cessation of Board service in which to exercise such
option for any or all of those vested shares of Common Stock.

                  4. In no event shall any automatic grant under this Article
Three remain exercisable after the expiration date of the ten (10)-year option
term. Upon the expiration of the applicable post-service exercise period under
subparagraph 1, 2 or 3 above or (if earlier) upon the expiration of the ten
(10)--year option term, the automatic grant shall terminate and cease to be
outstanding for any option shares in which the Optionee was vested at the time
of his or her cessation of Board service but which were not otherwise purchased
thereunder.

                  5. STOCKHOLDER RIGHTS. The holder of an automatic option grant
under this Article Three shall have none of the rights of a stockholder with
respect to any shares subject to such option until such individual shall have
exercised the option and paid the exercise price for the purchased shares.

                  6. REMAINING TERMS. The remaining terms and conditions of each
automatic option grant shall be as set forth in the form Non-statutory Stock
Option Agreement attached as Exhibit A.

                  III.     CORPORATE TRANSACTION/CHANGE IN CONTROL/HOSTILE
                           TAKE-OVER

               A. In the event of any Corporate Transaction, the shares of
Common Stock at the time subject to each outstanding option under this Article
Three but not otherwise vested shall automatically vest in full so that each
such option shall, immediately prior to the specified effective date for the
Corporate Transaction, become fully exercisable for all of the shares of Common
Stock at the time subject to that option and may be exercised for all or any
portion of such shares as fully-vested shares of Common Stock. Immediately
following the consummation of the Corporate Transaction, all automatic option
grants under this Article Three shall terminate and cease to be outstanding,
unless assumed by the successor corporation or its parent company.

               B. In connection with any Change in Control of the Corporation,
the shares of Common Stock at the time subject to each outstanding option under
this Article Three but not otherwise vested shall automatically vest in full so
that each such option shall, immediately prior to the specified effective date
for the Change in Control, become fully exercisable for all of the shares of
<PAGE>
Common Stock at the time subject to that option and may be exercised for all or
any portion of such shares as fully-vested shares of Common Stock. Each such
option shall remain fully exercisable for the option shares which vest in
connection with the Change in Control until the expiration or sooner termination
of the option term.

               C. Upon the occurrence of a Hostile Take-Over, the Optionee shall
have a thirty (30)-day period in which to surrender each option held by him or
her under this Article Three to the Corporation. The Optionee shall in return be
entitled to a cash distribution from the Corporation in an amount equal to the
excess of (i) the Take-Over Price of the shares of Common Stock at the time
subject to the surrendered option (whether or not the Optionee is otherwise at
the time vested in those shares) over (ii) the aggregate exercise price payable
for such shares. Such cash distribution shall be paid within five (5) days
following the consummation of the Hostile Take-Over. Stockholder approval of
this March 1997 restatement of the Plan shall constitute pre-approval of each
option subsequently granted with a surrender provision and the subsequent
surrender of that option in accordance with the terms and provisions of this
Section III.C. No additional approval of the Plan Administrator or the Board
shall be required at the time of the actual option cancellation and cash
distribution.

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

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

                                  ARTICLE FOUR

                             STOCK ISSUANCE PROGRAM
                             ----------------------

I.       TERMS AND CONDITIONS OF STOCK ISSUANCES

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

               A. CONSIDERATION.

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

                           (i) cash or cash equivalents (such as a personal
check or bank draft) paid the Corporation;

                          (ii) a promissory note payable to the Corporation's
order in one or more installments, which may be subject to cancellation in whole
or in part upon terms and conditions established by the Plan Administrator; or

                         (iii) past services rendered to the Corporation or
any parent or subsidiary corporation.

                  2. The consideration for any Newly Issued Shares issued under
this Stock Issuance Program shall have a value determined by the Plan
Administrator to be not less than one-hundred percent (100%) of the Fair Market
Value of those shares at the time of issuance.

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

                  1. Shares of Common Stock issued under the Stock Issuance
Program may, in the absolute discretion of the Plan Administrator, be fully and
immediately vested upon issuance or may vest in one or more installments over
the Participant's period of Service. The elements of the vesting schedule
applicable to any unvested shares of Common Stock issued under the Stock
Issuance Program, namely:

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

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

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

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

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

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

                  4. The Plan Administrator may in its discretion elect to waive
the surrender and cancellation of one or more unvested shares of Common Stock
(or other assets attributable thereto) which would otherwise occur upon the
non-completion of the vesting schedule applicable to such shares. Such waiver
shall result in the immediate vesting of the Participant's interest in the
shares of Common Stock as to which the waiver applies. Such waiver may be
effected at any time, whether before or after the Participant's cessation of
Service or the attainment or non-attainment of the applicable performance
objectives.

II. CORPORATE TRANSACTIONS/CHANGE IN CONTROL

               A. Upon the occurrence of any Corporate Transaction, all unvested
shares of Common Stock at the time outstanding under the Stock Issuance Program
shall immediately vest in full, except to the extent the Plan Administrator
imposes limitations in the Issuance Agreement which preclude such accelerated
vesting in whole or in part.

               B. The Plan Administrator shall have the discretionary authority,
exercisable either in advance of any actually-anticipated Change in Control or
at the time of an actual Change in Control, to provide for the immediate and
automatic vesting of one or more unvested shares outstanding under the Stock
Issuance Program at the time of such Change in Control. The Plan Administrator
shall also have full power and authority to condition any such accelerated
vesting upon the subsequent termination of the Participant's Service within a
specified period following the Change in Control.
<PAGE>
II.      TRANSFER RESTRICTIONS/SHARE ESCROW

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

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

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

                                  ARTICLE FIVE

                                  MISCELLANEOUS
                                  -------------

         I.       LOANS OR INSTALLMENT PAYMENTS

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

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

II. AMENDMENT OF THE PLAN AND AWARDS

                  I. The Board has complete and exclusive power and authority to
amend or modify the Plan (or any component thereof) in any or all respects
whatsoever. However, no such amendment or modification shall adversely affect
rights and obligations with respect to options at the time outstanding under the
<PAGE>
Plan, nor adversely affect the rights of any Participant with respect to Common
Stock issued under the Stock Issuance Program prior to such action, unless the
Optionee or Participant consents to such amendment. In addition, certain
amendments may require stockholder approval pursuant to applicable laws or
regulations.

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

III.     TAX WITHHOLDING

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

                  The Plan Administrator may, in its discretion and in
accordance with the provisions of this Section III of Article Five and such
supplemental rules as the Plan Administrator may from time to time adopt
(including the applicable safe-harbor provisions of SEC Rule 16b-3), provide any
or all holders of non-statutory options (other than the automatic grants made
pursuant to Article Three of the Plan) or unvested shares under the Plan with
the right to use shares of Common Stock in satisfaction of all or part of the
Federal, State and local income and employment withholding taxes to which such
holders may become subject in connection with the exercise of their options or
the vesting of their shares (the "Withholding Taxes"). Such right may be
provided to any such holder in either or both of the following formats:

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

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

         IV.      EFFECTIVE DATE AND TERM OF PLAN

                  A. The Plan was adopted by the Board on July 23, 1993, and was
approved by the stockholders on the same date. The Plan became effective on
September 29, 1993, the date on which the shares of the Corporation's Common
Stock were first registered under the 1934 Act. No further option grants or
stock issuances shall be made under the Predecessor Plans from and after the
Effective Date.

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

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

                  D. On March 16, 1995, the Board adopted an amendment to the
Plan which (i) increased the number of shares of Common Stock available for
issuance under the Plan by an additional 600,000 shares (as adjusted for the May
1995 stock split), (ii) provided for an automatic annual increase to the
existing share reserve on the first trading day in each of the next five (5)
fiscal years, beginning with the 1996 fiscal year and continuing through fiscal
year 2000, equal to 1.4% of the total number of shares of Common Stock
outstanding on the last trading day of the fiscal year immediately preceding the
fiscal year of each such share increase and (iii) imposed certain limitations
required under applicable Federal tax laws with respect to Incentive Option
grants. The amendment was approved by the stockholders at the 1995 Annual
Meeting on May 17, 1995.

                  E. On March 21, 1996, the Board adopted an amendment to the
Plan which (i) increased the number of shares of Common Stock available for
issuance under the Plan by an additional 600,000 shares, (ii) increased the
limit on the maximum number of shares of Common Stock issuable under the 1993
Plan prior to the required cessation of further Incentive Option grants to
3,780,000 shares plus an additional increase of 277,000 shares per fiscal year
over each of the next four (4) fiscal years, beginning with the 1997 fiscal
year, (iii) revised the Automatic Option Grant Program to eliminate the special
one-time option grant for 28,800 shares of Common Stock to each newly-elected or
newly-appointed non-employee Board member and implement a new option grant
program pursuant to which all eligible non-employee Board members will receive a
series of automatic option grants over their period of continued Board service.
The amendment was approved by the stockholders at the 1996 Annual Meeting.

                  F. On March 18, 1997, the Board adopted a series of amendments
to the Plan which (i) increased the number of shares of Common Stock reserved
for issuance over the term of the Plan by an additional 450,000 shares, (ii)
rendered all non-employee Board members eligible to receive option grants and
direct stock issuances under the Discretionary Option Grant and Stock Issuance
Programs, (iii) allowed unvested shares issued under the Plan and subsequently
repurchased by the Corporation at the option exercise price or direct issue
price paid per share to be reissued under the Plan, (iv) eliminated the plan
limitation which precluded the grant of additional Incentive Options once the
number of shares of Common Stock issued under the Plan, whether as vested or
unvested shares, exceeded a certain level, (v) removed certain restrictions on
the eligibility of non-employee Board members to serve as Plan Administrator,
and (vi) effected a series of additional changes to the provisions of the Plan
(including the stockholder approval requirements) in order to take advantage of
the recent amendments to Rule 16b-3 of the 1934 Act which exempts certain
officer and director transactions under the Plan from the short-swing liability
provisions of the federal securities laws. The March 18, 1997 amendments were
approved by the stockholders at the 1997 Annual Meeting.
