                                  SYBASE, INC.
             1991 AMENDED AND RESTATED EMPLOYEE STOCK PURCHASE PLAN
                         (As Amended on March 13, 1998)

      1.    Purpose

            This Amended and Restated Sybase, Inc. 1991 Employee Stock Purchase
Plan (the "Plan") is designed to encourage and assist employees of Sybase, Inc.
("Sybase") and participating subsidiaries (together, the "Company") to acquire
an equity interest in the Company through the purchase of shares of Sybase
common stock (the "Common Stock").

      2.    Administration

            The Plan shall be administered by the Board of Directors of Sybase
(or a committee of "disinterested" directors no fewer in number than required by
Rule 16b-3 of the Securities and Exchange Commission ("Rule 16b-3") as in effect
with respect to the Company from time to time, which in either case is referred
to as the "Board") in accordance with Rule 16b-3. The Board may from time to
time select a committee or persons (the "Administrator"), to be responsible for
any matters for which a "disinterested administrator" is not required by Rule
16-b. Subject to the express provisions of the Plan, to the overall supervision
of the Board, and to the limitations of Section 423 of the Internal Revenue Code
of 1986, as amended (the "Code"), the Administrator may administer and interpret
the Plan in any manner it believes to be desirable, and any such interpretation
shall be conclusive and binding on the Company and all participants.

      3.    Number of Shares

            (a)   The Company has reserved for sale under the Plan 7,500,000
shares of Common Stock (after giving effect to the November 1993 2-for-1 stock
split) less any shares sold under the Sybase 1991 Amended and Restated Foreign
Subsidiary Employee Stock Purchase Plan. Shares sold under the Plan may be newly
issued shares or shares reacquired in private transactions or open market
purchases, but all shares sold under the Plan, regardless of source, shall be
counted against the 7,500,000 share limitation.

            (b)   In the event of any reorganization, recapitalization, stock
split, reverse stock split, stock dividend, combination of shares, merger,
consolidation, offering of rights, or other similar change in the capital
structure of the Company, the Board may make such adjustment, if any, as it
deems appropriate in the number, kind, and purchase price of the shares
available for purchase under the Plan and in the maximum number of shares
subject to any option under the Plan.

      4.    Eligibility Requirements

            (a)   Each employee of the Company, except those described in the
next paragraph, shall become eligible to participate in the Plan in accordance
with Section 5 on the first Enrollment Date on or following commencement of his
or her employment 


   2
by the Company or following such period of employment as is designated by the
Board from time to time. Participation in the Plan is entirely voluntary.

            (b)   The following employees are not eligible to participate in the
Plan:

                  (i)   employees who would, immediately upon enrollment in the
Plan, own directly or indirectly, or hold options or rights to acquire stock
possessing, five percent or more of the total combined voting power or value of
all classes of stock of Sybase or any subsidiary of Sybase;

                  (ii)  employees who are customarily employed by the Company
less than 20 hours per week or less than five months in any calendar year; and

                  (iii) employees who are prohibited by the laws of the nation
of their residence or employment from participating in the Plan.

Employees who are also directors or officers of the Company may participate only
in accordance with Rule 16b-3 of the Securities and Exchange Commission.

            (c)   "Employee" shall mean any individual who is an employee of the
Company or a Participating Subsidiary within the meaning of Section 3401(c) of
the Code and the Treasury Regulations thereunder. "Subsidiary" shall mean any
corporation described in Section 425(e) or (f) of the Code. "Participating
Subsidiary" shall mean a subsidiary which has been designated by the
Administrator as covered by the Plan.

      5.    Enrollment

            Any eligible employee may enroll or re-enroll in the Plan each year
as of the first trading day of (i) the month immediately following the closing
of the Company's initial public offering of shares of its Common Stock on a
Registration Statement on Form S-1 (except that if such closing occurs during
the last month of a fiscal quarter (e.g. September), then the first Enrollment
Date will be the first trading day of the second month of the quarter
immediately following the closing (e.g. November)), (ii) the sixth month
following such month, and (iii) each yearly anniversary of such months (e.g. any
March and September or May and November), or such other days as may be
established by the Board from time to time (the "Enrollment Dates"). In order to
enroll, an eligible employee must complete, sign, and submit to the Company an
enrollment form. Any enrollment form received by the Company by the 15th day of
the month preceding an Enrollment Date (or by the Enrollment Date in the case of
employees hired after such 15th day), or such other date established by the
Administrator from time to time, will be effective on that Enrollment Date. For
purposes of the Plan, a "trading day" is any day on which regular trading occurs
on any established stock exchange or market system on which the Common Stock is
traded.

      6.    Grant of Option on Enrollment

            (a)   Enrollment or re-enrollment by a participant in the Plan on an
Enrollment Date will constitute the grant by the Company to the participant of
an option to purchase shares of Common Stock from the Company under the Plan.
Any participant whose option expires and who has not withdrawn from the Plan
will automatically be re-
   3

enrolled in the Plan and granted a new option on the Enrollment Date
immediately following the date on which the option expires.

            (b)   Except as provided in Section 9, each option granted under the
Plan shall have the following terms:

                  (i)   each option granted under the Plan will have a term of
not more than 24 months or such shorter option period as may be established by
the Board from time to time; notwithstanding the foregoing, however, whether or
not all shares have been purchased thereunder, the option will expire on the
earlier to occur of (A) the completion of the purchase of shares on the last
Purchase Date occurring within 24 months after the Enrollment Date for such
option, or such shorter option period as may be established by the Board before
an Enrollment Date for all options to be granted on such date or (B) the date on
which the employee's participation in the Plan terminates for any reason;

                  (ii)  payment for shares purchased under the option will be
made only through payroll withholding in accordance with Section 7;

                  (iii) purchase of shares upon exercise of the option will be
effected only on the Purchase Dates established in accordance with Section 8;

                  (iv)  the price per share under the option will be determined
as provided in Section 8;

                  (v)   the number of shares available for purchase under the
option will, unless otherwise established by the Board before an Enrollment Date
for all options to be granted on such date, be determined by dividing $25,000 by
the fair market value of a share of Common Stock on the Enrollment Date and by
multiplying the result by the number of calendar years included in whole or in
part in the period from grant to expiration of the option;

                  (vi)  the option (taken together with all other options then
outstanding under this and all other similar stock purchase plans of Sybase and
any subsidiary of Sybase, collectively "Options") will in no event give the
participant the right to purchase shares at a rate per calendar year which
accrues in excess of $25,000 of fair market value of such shares, less the fair
market value of any shares accrued and already purchased during such year under
Options which have expired or terminated, determined at the applicable
Enrollment Dates; and

                  (vii) the option will in all respects be subject to the terms
and conditions of the Plan, as interpreted by the Administrator from time to
time.

      7.    Payroll and Tax Withholding; Use by Company

            (a)   Each participant shall elect to have amounts withheld from his
or her compensation paid by the Company during the option period, at a rate
equal to any whole percentage up to a maximum of 10 percent, or such lesser
percentage as the Board may establish from time to time before an Enrollment
Date. Compensation includes regular salary payments, annual and quarterly
performance bonuses, hire-on bonuses, cash recognition awards, commissions,
overtime pay, shift premiums, and elective 

   4
contributions by the participant to qualified employee benefit plans, but
excludes all other payments including, without limitation, long-term disability
or workers compensation payments, car allowances, employee referral bonuses,
relocation payments, expense reimbursements (including but not limited to
travel, entertainment, and moving expenses), salary gross-up payments, and
non-cash recognition awards. The participant shall designate a rate of
withholding in his or her enrollment form and may elect to increase or decrease
the rate of contribution effective as of any Enrollment Date, by delivery to the
Company, not later than 15 days before such Enrollment Date, of a written notice
indicating the revised withholding rate.

            (b)   Payroll withholdings shall be credited to an account
maintained for purposes of the Plan on behalf of each participant, as soon as
administratively feasible after the withholding occurs. The Company shall be
entitled to use the withholdings for any corporate purpose, shall have no
obligation to pay interest on withholdings to any participant, and shall not be
obligated to segregate withholdings.

            (c)   Upon disposition of shares acquired by exercise of an option,
the participant shall pay, or make provision adequate to the Company for payment
of, all federal, state, and other tax (and similar) withholdings that the
Company determines, in its discretion, are required due to the disposition,
including any such withholding that the Company determines in its discretion is
necessary to allow the Company to claim tax deductions or other benefits in
connection with the disposition. A participant shall make such similar
provisions for payments that the Company determines, in its discretion, are
required due to the exercise of an option, including such provisions as are
necessary to allow the Company to claim tax deductions or other benefits in
connection with the exercise of the option.

      8.    Purchase of Shares

            (a)   On the last trading day of each month immediately preceding a
month containing an Enrollment Date, or on such other days as may be established
by the Board from time to time, prior to an Enrollment Date for all options to
be granted on an Enrollment Date (each a "Purchase Date"), the Company shall
apply the funds then credited to each participant's payroll withholdings account
to the purchase of whole shares of Common Stock. The cost to the participant for
the shares purchased under any option shall be not less than 85 percent of the
lower of:

                  (i)   the fair market value of the Common Stock on the
Enrollment Date for such option; or

                  (ii)  the fair market value of the Common Stock on that
Purchase Date.

The "fair market value" of the Common Stock on a date shall be the closing price
of the Common Stock on such date on any established stock exchange or market
system if the Common Stock is traded on such an exchange or market system (and
the largest such exchange or market system if the Common Stock is traded on more
than one), if the Common Stock is not so traded then the mean between the bid
and asked prices for Common Stock on such date as quoted on NASDAQ or reported
in The Wall Street Journal or similar publication if such prices are so quoted
or reported, or the fair market 


   5
value on such date as determined by the Administrator if shares of Common Stock
are not so traded, quoted, or reported.

            (b)   Any funds in an amount less than the cost of one share of
Common Stock left in a participant's payroll withholdings account on a Purchase
Date shall be carried forward in such account for application on the next
Purchase Date, and any additional amount shall be distributed to the participant
 .

            (c)   If at any Purchase Date, the shares available under the Plan
are less than the number all participants would otherwise be entitled to
purchase on such date, purchases shall be reduced proportionately to eliminate
the deficit. Any funds that cannot be applied to the purchase of shares due to
such a reduction shall be refunded to participants as soon as administratively
feasible.

      9.    Grant of Additional Options

            In addition to the options which may be granted under Section 6 of
this Plan, the Board, in its sole discretion, may grant, to each employee
satisfying the eligibility requirements of Section 4, additional options, for a
term not to exceed 27 months and for an identical number of shares. The options
granted hereunder shall be subject to the limitations of Section 6(b)(v) and
6(b)(vi); provided, however, that immediately before the grant of such
additional options, the limitations imposed thereby upon each recipient's
Options subject to payroll withholdings shall be adjusted to the minimum extent
necessary to permit the grant. The option price shall not be less than 85% of
the lower of (i) the fair market value of the stock on the grant date for such
option, or (ii) the fair market value on the date of exercise. The option will
be subject to such additional terms and conditions, not inconsistent with the
terms of the Plan as interpreted by the Administrator, as may be established
from time to time by the Board.

      10.   Withdrawal from the Plan

            A participant may withdraw from the Plan in full (but not in part)
at any time, effective after written notice thereof is received by the Company.
All funds credited to a participant's payroll withholdings account shall be
distributed to him or her without interest within 60 days after notice of
withdrawal is received by the Company. Any eligible employee who has withdrawn
from the Plan may enroll in the Plan again on any subsequent Enrollment Date in
accordance with the provisions of Section 5.

      11.   Termination of Employment

            Participation in the Plan terminates immediately when a participant
ceases to be employed by the Company for any reason whatsoever (including death
or disability) or otherwise becomes ineligible to participate in the Plan. As
soon as administratively feasible after termination, the Company shall pay to
the participant or his or her beneficiary or legal representative, all amounts
credited to the participant's payroll withholdings account; provided, however,
that if a participant ceases to be employed by the Company because of the
commencement of employment with a Subsidiary of the Company that is not a
Participating Subsidiary, funds then credited to such participant's payroll
withholdings account shall be applied to the purchase of whole 


   6
shares of Common Stock at the next Purchase Date and any funds remaining after
such purchase shall be paid to the participant.

      12.   Designation of Beneficiary

            (a)   Each participant may designate one or more beneficiaries in
the event of death and may, in his or her sole discretion, change such
designation at any time. Any such designation shall be effective upon receipt in
written form by the Company and shall control over any disposition by will or
otherwise.

            (b)   As soon as administratively feasible after the death of a
participant, amounts credited to his or her account shall be paid in cash to the
designated beneficiaries or, in the absence of a designation, to the executor,
administrator, or other legal representative of the participant's estate. Such
payment shall relieve the Company of further liability with respect to the Plan
on account of the deceased participant. If more than one beneficiary is
designated, each beneficiary shall receive an equal portion of the account
unless the participant has given express contrary written instructions.

      13.   Assignment

            (a)   The rights of a participant under the Plan shall not be
assignable by such participant, by operation of law or otherwise. No participant
may create a lien on any funds, securities, rights, or other property held by
the Company for the account of the participant under the Plan, except to the
extent that there has been a designation of beneficiaries in accordance with the
Plan, and except to the extent permitted by the laws of descent and distribution
if beneficiaries have not been designated.

            (b)   A participant's right to purchase shares under the Plan shall
be exercisable only during the participant's lifetime and only by him or her,
except that a participant may direct the Company in the enrollment form to issue
share certificates to the participant and his or her spouse in community
property, to the participant jointly with one or more other persons with right
of survivorship, or to certain forms of trusts approved by the Administrator.

      14.   Administrative Assistance

            If the Administrator in its discretion so elects, it may retain a
brokerage firm, bank or other financial institution to assist in the purchase of
shares, delivery of reports, or other administrative aspects of the Plan. If the
Administrator so elects, each participant shall (unless prohibited by the laws
of the nation of his or her employment or residence) be deemed upon enrollment
in the Plan to have authorized the establishment of an account on his or her
behalf at such institution. Shares purchased by a participant under the Plan
shall be held in the account in the name in which the share certificate would
otherwise be issued pursuant to Section 13(b).

      15.   Costs

            All costs and expenses incurred in administering the Plan shall be
paid by the Company, except that any stamp duties or transfer taxes applicable
to participation in the Plan may be charged to the account of such participant
by the Company. Any 

   7
brokerage fees for the purchase of shares by a participant shall be paid by the
Company, but brokerage fees for the resale of shares by a participant shall be
borne by the participant.

      16.   Equal Rights and Privileges

            All eligible employees shall have equal rights and privileges with
respect to the Plan so that the Plan qualifies as an "employee stock purchase
plan" within the meaning of Section 423 of the Code and the related Treasury
Regulations. Any provision of the Plan which is inconsistent with Section 423 of
the Code shall without further act or amendment by the Company or the Board be
reformed to comply with the requirements of Section 423. This Section 16 shall
take precedence over all other provisions of the Plan.

      17.   Applicable Law

            The Plan shall be governed by the substantive laws (excluding the
conflict of laws rules) of the State of California.

      18.   Modification and Termination

            (a)   The Board may amend, alter, or terminate the Plan at any time,
including amendments to outstanding options. No amendment shall be effective
unless within 12 months after it is adopted by the Board, it is approved by the
holders of a majority of the votes cast at a duly held shareholders' meeting at
which a quorum of the voting power of the Company is represented in person or by
proxy, if such amendment would: 

                   (i) increase the number of shares reserved for purchase under
the Plan; or

                  (ii)  require shareholder approval in order to comply with SEC
Rule 16b-3.

            (b)   In the event the Plan is terminated, the Board may elect to
terminate all outstanding options either immediately or upon completion of the
purchase of shares on the next Purchase Date, or may elect to permit options to
expire in accordance with their terms (and participation to continue through
such expiration dates). If the options are terminated prior to expiration, all
funds contributed to the Plan that have not been used to purchase shares shall
be returned to the participants as soon as administratively feasible.

            (c)   In the event of the sale of all or substantially all of the
assets of Sybase or the Company, or the merger of Sybase or the Company with or
into another corporation, or the dissolution or liquidation of Sybase, a
Purchase Date shall occur on the trading day immediately preceding the date of
such event, unless otherwise provided by the Board in its sole discretion,
including provision for the assumption or substitution of each option under the
Plan by the successor or surviving corporation, or a parent or subsidiary
thereof.

      19.   Rights as an Employee

   8
            Nothing in the Plan shall be construed to give any person the right
to remain in the employ of the Company or to affect the Company's right to
terminate the employment of any person at any time with or without cause.

      20.   Rights as a Shareholder; Delivery of Certificates

            Unless otherwise determined by the Board, certificates evidencing
shares purchased on any Purchase Date shall be delivered to participants as soon
as administratively feasible. Participants shall be treated as the owners of
their shares effective as of the Purchase Date.

      21.   Board and Shareholder Approval

            The Plan was approved by the Board of Directors on April 30, 1991,
and by the holders of a majority of the votes cast at a duly held shareholders'
meeting on June 13, 1991, at which a quorum of the voting power of the Company
was represented in person or by proxy. As amended and restated to adopt
amendments not requiring shareholder approval, the Plan was approved by the
Board of Directors on July 30, 1991. The Plan was amended by the Board of
Directors on January 28, 1993, January 27, 1994, January 24, 1995 and January
21, 1997 and such amendments were approved by the holders of a majority of the
votes cast at a duly held shareholders' meeting on May 18, 1993, May 24, 1994,
May 23, 1995, and May 20, 1997 respectively. The Plan also was amended by the
Board of Directors on March 13, 1998.

                            1991 AMENDED AND RESTATED
                 FOREIGN SUBSIDIARY EMPLOYEE STOCK PURCHASE PLAN
                           (As Amended March 13, 1998)

      1.    Purpose

            This Amended and Restated Sybase, Inc. 1991 Foreign Subsidiary
Employee Stock Purchase Plan (the "Plan") is designed to encourage and assist
employees of designated subsidiaries of Sybase, Inc. ("Sybase" or the "Company")
to acquire an equity interest in the Company through the purchase of shares of
Sybase common stock (the "Common Stock").

      2.    Administration

            The Plan shall be administered by the Board of Directors of Sybase
or a committee (the "Committee") selected from time to time by the Board.
Subject to the express provisions of the Plan and to the overall supervision of
the Board, the Committee may administer and interpret the Plan in any manner it
believes to be desirable, and any such interpretation shall be conclusive and
binding on the Company and all participants. If and to the extent that Rule
16b-3 of the Securities and Exchange Commission ("Rule 16b-3") becomes
applicable to the Plan, the Board and the Committee shall use their best efforts
to cause the Plan to be administered in accordance therewith.

      3.    Number of Shares

            (a)   The Company has reserved for sale under the Plan 7,500,000
shares of Common Stock (after giving effect to the November 1993 2-for-1stock
split) less any shares sold under the Sybase 1991 Amended and Restated Employee
Stock Purchase Plan. Shares sold under the Plan may be newly issued shares or
shares reacquired in private transactions or open market purchases, but all
shares sold under the Plan, regardless of source, shall be counted against the
7,500,000 share limitation.

            (b)   In the event of any reorganization, recapitalization, stock
split, reverse stock split, stock dividend, combination of shares, merger,
consolidation, offering of rights, or other similar change in the capital
structure of the Company, the Committee may make such adjustment, if any, as it
deems appropriate in the number, kind, and purchase price of the shares
available for purchase under the Plan and in the maximum number of shares
subject to any option under the Plan.

      4.    Designation of Subsidiaries; Employee Eligibility Requirements

            (a)   The Board may at any time designate one or more Subsidiaries
as participating in the Plan. The names of all Participating Subsidiaries shall
be shown on Exhibit A to the Plan, which shall be amended from time to time to
reflect additions and deletions of Participating Subsidiaries; failure to show a
Participating Subsidiary on Exhibit A shall not, however, prevent otherwise
eligible employees of that Subsidiary from participating in the Plan. No
Subsidiary participating in the Company's 1991 Employee Stock Purchase Plan may
be designated for participating in the Plan.


   10
            (b)   Each employee of a Participating Subsidiary, except those
described in the next paragraph, shall become eligible to participate in the
Plan in accordance with Section 5 on the first Enrollment Date on or following
commencement of his or her employment by the Participating Subsidiary or
following such period of employment as is designated by the Board from time to
time. Participating in the Plan is entirely voluntary.

            (c)   Except to the extent otherwise determined by the Board or
provided by the Plan, the following employees are not eligible to participate in
the Plan:

                  (i)   employees who would, immediately upon enrollment in the
Plan, own directly or indirectly, or hold options or rights to acquire stock
possessing, five percent or more of the total combined voting power or value of
all classes of stock of Sybase or any subsidiary of Sybase;

                  (ii)  employees who are customarily employed by the
Participating Subsidiary less than 20 hours per week or less than five months in
any calendar year; and

                  (iii) employees who are prohibited by the laws of the nation
of their residence or employment from participating in the Plan.

Employees who are also directors or officers of the Company may participate only
in accordance with Rule 16b-3 of the Securities and Exchange Commission.

            (d)   "Employee" shall mean any individual who is an employee of a
Participating Subsidiary within the meaning of Section 3401(c) of the Internal
Revenue Code of 1986, as amended (the "Code") and the Treasury Regulations
thereunder. "Subsidiary" shall mean any corporation described in Section 425(e)
or (f) of the Code. "Participating Subsidiary" shall mean a subsidiary which has
been designated by the Committee as covered by the Plan.

      5.    Enrollment

            Any eligible employee may enroll or re-enroll in the Plan each
year as of the first trading day of (i) the month immediately following the
closing of the Company's initial public offering of shares of its Common Stock
on a Registration Statement on Form S-1 (except that if such closing occurs
during the last month of a fiscal quarter (e.g., September), then the first
Enrollment Date will be the first trading day of the second month of the quarter
immediately following the closing (e.g., November)), (ii) the sixth month
following such month, and (iii) each yearly anniversary of such months (e.g.,
any March and September or May and November), or such other days as may be
established by the Board from time to time (the "Enrollment Dates"). In
addition, for purposes of participating in the Plan by an eligible employee
following termination of such employee's participation in the Sybase 1991
Amended and Restated Employee Stock Purchase Plan (the "U.S. Plan") a deemed
Enrollment Date may be designated corresponding to the employee's most recent
Enrollment Date under the U.S. Plan. In order to enroll, an eligible employee
must complete, sign, and submit to the Company or the Participating Subsidiary
an enrollment form. Any enrollment form received by the 

   11
Participating Subsidiary or the Company by the 15th day of the month preceding
an Enrollment Date (or by the Enrollment Date in the case of employees hired
after such 15th day), or such other date established by the Committee from time
to time, will be effective on that Enrollment Date. For purposes of the Plan, a
"trading day" is any day on which regular trading occurs on any established
stock exchange or market system on which the Common Stock is traded.

      6.    Grant of Option on Enrollment

            (a)   Enrollment or re-enrollment by a participant in the Plan on an
Enrollment Date will constitute the grant by the Company to the participant of
an option to purchase shares of Common Stock from the Company under the Plan.
Any participant whose option expires and who has not withdrawn from the Plan
will automatically be re-enrolled in the Plan and granted a new option on the
Enrollment Date immediately following the date on which the option expires.

            (b)   Except as provided in Section 9 or Section 11, each option
granted under the Plan shall have the following terms unless otherwise
determined by the Board:

                  (i)   each option granted under the Plan will have a term of
not more than 24 months or such shorter option period as may be established by
the Board from time to time; notwithstanding the foregoing, however, whether or
not all shares have been purchased thereunder, the option will expire on the
earlier to occur of (A) the completion of the purchase of shares on the last
Purchase Date occurring within 24 months after the Enrollment Date for such
option, or such shorter option period as may be established by the Board before
an Enrollment Date for all options to be granted on such date or (B) the date on
which the employee's participation in the Plan terminates for any reason;

                  (ii)  payment for shares purchased under the option will be
made only through payroll withholding in accordance with Section 7;

                  (iii) purchase of shares upon exercise of the option will be
effected only on the Purchase Dates established in accordance with Section 8;

                  (iv)  the price per share under the option will be determined
as provided in Section 8;

                  (v)   the number of shares available for purchase under an
option will, unless otherwise established by the Board before an enrollment Date
for all options to be granted on such date, be determined by dividing $25,000 by
the fair market value of a share of Common Stock on the Enrollment Date and by
multiplying the result by the number of calendar years included in whole or in
part in the period from grant to expiration of the option;

                  (vi)  the option (taken together with all other options then
outstanding under this and all other similar stock purchase plans of Sybase and
any subsidiary of Sybase, collectively "Options") will in no event give the
participant the right to purchase shares at a rate per calendar year which
accrues in excess of $25,000 of fair market value of such shares, less the fair
market value of any shares accrued and 

   12
already purchased during such year under Options which have expired or
terminated, determined at the applicable Enrollment Dates; and

                  (vii) the option will in all respects be subject to the terms
and conditions of the Plan, as interpreted by the Committee from time to time.

      7.    Payroll and Tax Withholding; Use by Participating Subsidiary and the
Company

            (a)   Each participant shall elect to have amounts withheld from his
or her compensation and paid to the Company during the option period, at a rate
equal to any whole percentage up to a maximum of 10 percent, or such lesser
percentage as the Board may establish from time to time before an Enrollment
Date. Compensation includes regular salary payments, annual and quarterly
performance bonuses, hire-on bonuses, cash recognition awards, commissions,
overtime pay, shift premiums, and elective contributions by the participant to
qualified employee benefit plans, but excludes all other payments including,
without limitation, long-term disability or workers compensation payments, car
allowances, employee referral bonuses, relocation payments, expense
reimbursements (including but not limited to travel, entertainment, and moving
expenses), salary gross-up payments, and non-cash recognition awards. The
participant shall designate a rate of withholding in his or her enrollment form
and may elect to increase or decrease the rate of contribution effective as of
any Enrollment Date, by delivery to the Participating Subsidiary, not later than
15 days before such Enrollment Date, of a written notice indicating the revised
withholding rate.

            (b)   Payroll withholdings shall be credited to an account
maintained for purposes of the Plan on behalf of each participant in local
currency, as soon as administratively feasible after the withholding occurs. The
Participating Subsidiary and the Company shall be entitled to use the
withholdings for any corporate purpose, shall have no obligation to pay interest
on withholdings to any participant, and shall not be obligated to segregate
withholdings.

            (c)   Upon disposition of shares acquired by exercise of an option,
the participant shall pay, or make provision adequate to the Company and the
Participating Subsidiary for payment of, all federal, state, and other tax (and
similar) withholdings that the Company or the Participating Subsidiary
determines, in its discretion, are required due to the disposition, including
any such withholding that the Company or the Participating Subsidiary
determines, in its discretion, is necessary to allow the Company or the
Participating Subsidiary to claim tax deductions or other benefits in connection
with the disposition. A participant shall make such similar provisions for
payment that the Company or the Participating Subsidiary determines, in its
discretion, are required due to the exercise of an option, including such
provisions as are necessary to allow the Company or the Participating Subsidiary
to claim tax deductions or other benefits in connection with the exercise of the
option.

      8.    Purchase of Shares

            (a)   On the last trading day of each month immediately preceding a
month containing an Enrollment Date, or on such other days as may be established
by the Board from time to time, prior to an Enrollment Date for all options to
be granted on an 

   13
Enrollment Date (each a "Purchase Date"), the Company shall convert each
participant's account balance, including amounts carried forward pursuant to
Section 8(b) below, to U.S. Dollars determined as of such Purchase Date (or
applying such formula as may be established by the Administrator) and shall
apply the funds then credited to each participant's payroll withholdings account
to the purchase of whole shares of Common Stock. The cost to the participant for
the shares purchased under any option shall be not less than 85 percent of the
lower of:

                  (i)   the fair market value of the Common Stock on the
Enrollment Date for such option; or

                  (ii)  the fair market value of the Common Stock on that
Purchase Date.

            The "fair market value" of the Common Stock on a date shall be the
closing price of the Common Stock on such date on any established stock exchange
or market system if the Common Stock is traded on such an exchange or market
system (and the largest such exchange or market system if the Common Stock is
traded on more than one), if the Common Stock is not so traded then the mean
between the bid and asked prices for Common Stock on such date as quoted on
NASDAQ or reported in The Wall Street Journal or similar publication if such
prices are so quoted or reported, or the fair market value on such date as
determined by the Committee if shares of Common Stock are not so traded, quoted,
or reported.

            (b)   Any funds in an amount less than the cost of one share of
Common Stock left in a participant's payroll withholdings account on a Purchase
Date shall be carried forward in such account for application on the next
Purchase Date, and any additional amount shall be distributed to the
participant.

            (c)   If at any Purchase Date, the shares available under the Plan
are less than the number all participants would otherwise be entitled to
purchase on such date, purchases shall be reduced proportionately to eliminate
the deficit. Any funds that cannot be applied to the purchase of shares due to
such a reduction shall be refunded to participants as soon as administratively
feasible.

      9.    Grant of Additional Options

            In addition to the options which may be granted under Section 6
of this Plan, the Committee, in its sole discretion, may grant, to each employee
of a Participating Subsidiary satisfying the eligibility requirements of Section
4, additional options, for a term not to exceed 27 months and for an identical
number of shares. The options granted hereunder shall be subject to the
limitations of Section 6(b)(v) and 6(b)(vi); provided, however, that immediately
before the grant of such additional options, the limitations imposed thereby
upon each recipient's Options subject to payroll withholdings shall be adjusted
to the minimum extent necessary to permit the grant. The option price shall not
be less than 85% of the lower of (i) the fair market value of the stock on the
grant date for such option, or (ii) the fair market value on the date of
exercise. The option will be subject to such additional terms and conditions,
not inconsistent with the terms of the Plan as interpreted by the Committee, as
may be established from time to time by the Board.


   14
      10.   Withdrawal from the Plan

            A participant may withdraw from the Plan in full (but not in part)
at any time, effective after written notice thereof is received by the Company.
All funds credited to a participant's payroll withholdings account shall be
distributed to him or her without interest within 60 days after notice of
withdrawal is received by the Company. Any eligible employee who has withdrawn
from the Plan may enroll in the Plan again on any subsequent Enrollment Date in
accordance with the provisions of Section 5.

      11.   Termination of Employment

            (a)   Except as provided in Section 11(b) below, participation in
the Plan terminates immediately when a participant ceases to be employed by a
Participating Subsidiary for any reason whatsoever (including death or
disability) or otherwise becomes ineligible to participate in the Plan. Transfer
of a participant's employment from one Participating Subsidiary to another
without material interruption shall not be deemed a termination of employment
for purposes of this Section 11. As soon as administratively feasible after
termination, the Company shall pay to the participant or his or her beneficiary
or legal representative, all amounts credited to the participant's payroll
withholdings account.

            (b)   Following transfer of a participant's employment without
material interruption from a Participating Subsidiary to the Company or any
subsidiary of the Company other than a participating Subsidiary, any outstanding
option granted to such participant under the Plan shall not terminate until the
occurrence of the earliest of: (i) the last Purchase Date included in the term
of such option; (ii) enrollment of the participant in the U.S. Plan; or (iii)
any event or change of condition or status (other than the transfer described in
this Section 11(b)) that would have caused the option to terminate if the
transfer of employment described in this Section 11(b) had not occurred. While
an option remains outstanding pursuant to this Section 11(b), the Company or
other subsidiary to which the participant is transferred shall, in accordance
with Section 7, effect payroll withholdings under the option and shall remit
them to the Company or the Participating Subsidiary that employed the
participant at the time of the transfer; such withholdings shall be credited to
the Participant's payroll withholdings account at the time withheld by the
Company or other subsidiary and in the currency of the Company or subsidiary by
which the participant is employed at the time of the withholdings.

      12.   Designation of Beneficiary

            (a)   Each participant may designate one or more beneficiaries in
the event of death and may, in his or her sole discretion, change such
designation at any time. Any such designation shall be effective upon receipt in
written form by the Company or the Participating Subsidiary and shall control
over any disposition by will or otherwise.

            (b)   As soon as administratively feasible after the death of a
participant, amounts credited to his or her account shall be paid in cash to the
designated beneficiaries or, in the absence of a designation, to the executor,
administrator, or other legal representative of the participant's estate. Such
payment shall relieve the 

   15
Participating Subsidiary of further liability with respect to the Plan on
account of the deceased participant. If more than one beneficiary is designated,
each beneficiary shall receive an equal portion of the account unless the
participant has given express contrary written instructions.

      13.   Assignment

            (a)   The rights of a participant under the Plan shall not be
assignable by such participant, by operation of law or otherwise. No participant
may create a lien on any funds, securities, rights, or other property held by
the Company or the Participating Subsidiary for the account of the participant
under the Plan, except to the extent that there has been a designation of
beneficiaries in accordance with the Plan, and except to the extent permitted by
the laws of descent and distribution if beneficiaries have not been designated.

            (b)   A participant's right to purchase shares under the Plan shall
be exercisable only during the participant's lifetime and only by him or her,
except that a participant may direct the Company in the enrollment form to issue
share certificates to the participant and his or her spouse in community
property, to the participant jointly with one or more other persons with right
of survivorship, or to certain forms of trusts approved by the Committee.

      14.   Administrative Assistance

            If the Committee in its discretion so elects, it may retain a
brokerage firm, bank, or other financial institution to assist in the purchase
of shares, delivery of reports, or other administrative aspects of the Plan. If
the Committee so elects, each participant shall (unless prohibited by the laws
of the nation of his or her employment or residence) be deemed upon enrollment
in the Plan to have authorized the establishment of an account on his or her
behalf at such institution. Shares purchased by a participant under the Plan
shall be held in the account in the name in which the share certificate would
otherwise be issued pursuant to Section 13(b).

      15.   Costs

            All costs and expenses incurred in administering the Plan shall be
paid by the Company, except that any stamp duties or transfer taxes applicable
to participation in the Plan may be charged to the account of such participant
by the Company. Any brokerage fees for the purchase of shares by a participant
shall be paid by the Company, but brokerage fees for the resale of shares by a
participant shall be borne by the participant.

      16.   Equivalent Rights and Privileges

            It is intended that all eligible employees shall have substantially
equivalent rights and privileges with respect to the Plan; notwithstanding any
other provision of the Plan, however, the Committee may make such changes in the
terms of eligibility and participation from Subsidiary to Subsidiary that it
determines, in its discretion, to be necessary or desirable to reflect or comply
with local laws or conditions.


   16
      17.   Applicable Law

      The Plan shall be governed by the substantive laws (excluding the conflict
of laws rules) of the State of California.

      18.   Modification and Termination

            (a)   The Board may amend, alter, or terminate the Plan at any time,
including amendments to outstanding options. To the extent required for the Plan
to comply with Rule 16b-3 or applicable tax laws or regulations, no amendment
shall be effective unless within 12 months after it is adopted by the Board, it
is approved by the holders of a majority of the votes cast at a duly held
shareholders' meeting at which a quorum of the voting power of the Company is
represented in person or by proxy, if such amendment would:

            (i) increase the number of shares reserved for purchase under the
Plan;

            (ii) increase the benefits accruing to participants under the Plan;
or

            (iii) modify the requirements as to eligibility for participation in
the Plan.

            (b)   In the event the Plan is terminated, the Board may elect to
terminate all outstanding options either immediately or upon completion of the
purchase of shares on the next Purchase Date, or may elect to permit options to
expire in accordance with their terms (and participation to continue through
such expiration dates). If the options are terminated prior to expiration, all
funds contributed to the Plan that have not been used to purchase shares shall
be returned to the participants as soon as administratively feasible.

            (c)   In the event of the sale of all or substantially all of the
assets of Sybase or a Participating Subsidiary, or the merger of Sybase or a
Participating Subsidiary with or into another corporation, or the dissolution or
liquidation of Sybase, a Purchase Date shall occur on the trading day
immediately preceding the date of such event, unless otherwise provided by the
Board in its sole discretion, including provision for the assumption or
substitution of each option under the Plan by the successor or surviving
corporation, or a parent or subsidiary thereof.

      19.   Rights as an Employee

            Nothing in the Plan shall be construed to give any person the right
to remain in the employ of the Participating Subsidiary or to affect the
Participating Subsidiary's right to terminate the employment of any person at
any time with or without cause.

      20.   Rights as a Shareholder; Delivery of Certificates


   17
            Unless otherwise determined by the Board, certificates evidencing
shares purchased on any Purchase Date shall be delivered to participants as soon
as administratively feasible. Participants shall be treated as the owners of
their shares effective as of the Purchase Date.

      21.   Board and Shareholder Approval

            The Plan was approved by the Board of Directors on April 30, 1991,
and by the holders of a majority of the votes cast at a duly held shareholders'
meeting on June 13, 1991, at which a quorum of the voting power of the Company
was represented in person or by proxy. As amended and restated to adopt
amendments not requiring shareholder approval, the Plan was approved by the
Board of Directors on July 30, 1991. The Plan was amended by the Board of
Directors on January 28, 1993, January 27, 1994, January 24, 1995 and January
21, 1997 and such amendments were approved by the holders of a majority of the
votes cast at a duly held shareholders' meeting on May 18, 1993, May 24, 1994,
May 23, 1995, and May 20, 1997 respectively. The Plan also was amended by the
Board of Directors on March 13, 1998.
