PART II:  INFORMATION REQUIRED IN THE REGISTRATION STATEMENT

ITEM 3         INFORMATION INCORPORATED BY REFERENCE

     The following documents and information heretofore filed with the
Securities and Exchange Commission (the "Commission") are hereby incorporated by
reference:

       ITEM 3(a)

          The Registrant's latest annual report on Form 10-K filed pursuant to
     Section 13(a) or 15(d) of the Securities Exchange Act of 1934, as amended
     (the "Exchange Act"), which contains audited financial statements for the
     Registrant's latest fiscal year for which such statements have been filed.

       ITEM 3(b)

          All other reports filed by the Registrant pursuant to Section 13(a) or
     15(d) of the Exchange Act, since the end of the fiscal year covered by the
     annual report on Form 10-K referred to in (a) above.

       ITEM 3(c)

          The description of Registrant's Common Stock contained in the
     Registrant's Registration Statement on Form 8-A filed with the Commission
     under Section 12 of the Exchange Act on December 17, 1992, as amended by
     Amendment No. 1 to Form 8-A filed on January 29, 1993, and including any
     further amendment or report filed for the purpose of updating such
     description.

          All documents subsequently filed by the Registrant pursuant to
     Sections 13(a), 13(c), 14 and 15(d) of the Exchange Act, prior to the
     filing of a post-effective amendment which indicates that all securities
     offered have been sold or which deregisters all securities then remaining
     unsold, shall be deemed to be incorporated by reference in this
     Registration Statement and to be part hereof from the date of filing of
     such documents.

ITEM 4         DESCRIPTION OF SECURITIES

          Not Applicable.

ITEM 5         INTERESTS OF NAMED EXPERTS AND COUNSEL

          Certain legal matters with respect to the legality of the issuance of
     the Common Stock registered hereby will be passed upon for the Registrant
     by Venture Law Group, Menlo Park, California.  As of the date of this
     Registration Statement, certain members of Venture Law Group and investment
     partnerships of which members of Venture Law Group are partners
     beneficially own 28,000 shares of the Registrant's Common Stock.

ITEM 6         INDEMNIFICATION OF DIRECTORS AND OFFICERS

          The Registrant's Articles of Incorporation limit the liability of
     directors for monetary damages


                                         -4-
<PAGE>

     to the maximum extent permitted by California law.  Such limitation of
     liability has no effect on the availability of equitable remedies, such as
     injunctive relief or rescission.  The Registrant's By-laws include
     provisions whereby the directors, officers and other agents of the Company
     are to be indemnified against certain liabilities to the fullest extent
     permitted by the California Corporations Code.  Pursuant to approval of the
     Board of Directors, the Registrant entered into indemnification agreements
     with each of its current directors and officers which provide for
     indemnification of, and advancement of expenses to, such persons to the
     greatest extent permitted by the California Corporations Code, including by
     reason of action or inaction occurring  in the past and circumstances in
     which indemnification and the advancement of expenses are discretionary
     under California law.  It is the opinion of the staff of the Securities and
     Exchange Commission that indemnification provisions such as those contained
     in these agreements have no effect on a director's or officer's liability
     under the federal securities laws.  In addition, the Registrant maintains
     an insurance policy covering its officers and directors under which the
     insurer has agreed to pay, subject to certain exclusions, the amount of any
     claim made against the officers or directors of the Registrant for wrongful
     acts that such officers or directors may otherwise be required to pay or
     for which the Registrant is required to indemnify such officers or
     directors.

ITEM 9         UNDERTAKINGS

     A.   The undersigned Registrant hereby undertakes:

          (1)  To file, during any period in which offers or sales are being
made, a post-effective amendment to this Registration Statement to include any
material information with respect to the plan of distribution not previously
disclosed in the Registration Statement or any material change to such
information in the Registration Statement.

          (2)  That, for the purpose of determining any liability under the
Securities Act of 1933, each such post-effective amendment shall be deemed to be
a new registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

          (3)  To remove from registration by means of a post-effective
amendment any of the securities being registered which remain unsold at the
termination of the offering.

     B.   The undersigned Registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
Registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
Exchange Act (and, where applicable, each filing of an employee benefit plan's
annual report pursuant to Section 15(d) of the Exchange Act) that is
incorporated by reference in the Registration Statement shall be deemed to be a
new registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

     C.   Insofar as indemnification for liabilities arising under the
Securities Act of 1933 may be permitted to directors, officers and controlling
persons of the Registrant pursuant to the foregoing provisions, or otherwise,
the Registrant has been advised that in the opinion of the Securities and
Exchange Commission such indemnification is against public policy as expressed
in the Act and is, therefore, unenforceable.  In the event that a claim for
indemnification against such liabilities (other than the payment by the
Registrant of expenses incurred or paid by a director, officer or controlling
person of the Registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the Registrant will, unless in
the opinion of its counsel the matter has been settled by controlling precedent,
submit to a court of appropriate jurisdiction the question whether such
indemnification by it is against public policy as expressed in the Act and will
be governed by the final adjudication of such issue.

                             CENTURA SOFTWARE CORPORATION

                          1992 EMPLOYEE STOCK PURCHASE PLAN

                             (AS AMENDED JUNE 17, 1998)

     The following constitute the provisions of the 1992 Employee Stock Purchase
Plan of Centura Software Corporation.

     1.   PURPOSE.  The purpose of the Plan is to provide employees of the
Company and its Designated Subsidiaries with an opportunity to purchase Common
Stock of the Company.  It is the intention of the Company to have the Plan
qualify as an "Employee Stock Purchase Plan" under Section 423 of the Internal
Revenue Code of 1986, as amended.  The provisions of the Plan shall,
accordingly, be construed so as to extend and limit participation in a manner
consistent with the requirements of that section of the Code.

     2.   DEFINITIONS.

          (a)  "BOARD"  shall mean the Board of Directors of the Company.

          (b)  "CODE"  shall mean the Internal Revenue Code of 1986, as amended.

          (c)  "COMMON STOCK"  shall mean the Common Stock of the Company.

          (d)  "COMPANY"  shall mean Centura Software Corporation, a California
corporation.

          (e)  "COMPENSATION" shall mean all regular straight time gross
earnings, excluding payments for overtime, shift premium, incentive
compensation, incentive payments, bonuses, commissions and other compensation.

          (f)  "CONTINUOUS STATUS AS AN EMPLOYEE" shall mean the absence of any
interruption or termination of service as an Employee.  Continuous Status as an
Employee shall not be considered interrupted in the case of a leave of absence
agreed to in writing by the Company, provided that such leave is for a period of
not more than 90 days or reemployment upon the expiration of such leave is
guaranteed by contract or statute.

          (g)  "CONTRIBUTIONS" shall mean all amounts credited to the account of
a participant pursuant to the Plan.

          (h)  "DESIGNATED SUBSIDIARIES" shall mean the Subsidiaries which have
been designated by the Board from time to time in its sole discretion as
eligible to participate in the Plan.


<PAGE>

          (i)  "EMPLOYEE" shall mean any person, including an officer, who is
customarily employed for at least twenty (20) hours per week and more than five
(5) months in a calendar year by the Company or one of its Designated
Subsidiaries.

          (j)  "EXCHANGE ACT" shall mean the Securities Exchange Act of 1934, as
amended.

          (k)  "EXERCISE DATE" shall mean the last day of each Offering Period
of the Plan.

          (l)  "OFFERING DATE" shall mean the first business day of each
Offering Period of the Plan, except that in the case of an individual who
becomes an eligible Employee after the first business day of an Offering Period
but prior to the first business day of the last calendar quarter of such
Offering Period, the term "Offering Date" shall mean the first business day of
the calendar quarter coinciding with or next succeeding the day on which that
individual becomes an eligible Employee.

               Options granted after the first business day of an Offering
Period will be subject to the same terms as the options granted on the first
business day of such Offering Period except that they will have a different
grant date (thus, potentially, a different exercise price) and, because they
expire at the same time as the options granted on the first business day of such
Offering Period, a shorter term.

          (m)  "OFFERING PERIOD" shall mean a period of three (3) months.

          (n)  "PLAN" shall mean this Employee Stock Purchase Plan.

          (o)  "REPORTING PERSON" shall mean an officer, director or other
employee who is subject to Section 16 of the Exchange Act.

          (p)  "SUBSIDIARY"  shall mean a corporation, domestic or foreign, of
which not less than 50% of the voting shares are held by the Company or a
Subsidiary, whether or not such corporation now exists or is hereafter organized
or acquired by the Company or a Subsidiary.

     3.   ELIGIBILITY.

          (a)  Any person who is an Employee as of the Offering Date of a given
Offering Period shall be eligible to participate in such Offering Period under
the Plan, provided that such person was not eligible to participate in such
Offering Period as of any prior Offering Date, and further, subject to the
requirements of Section 5(a) and the limitations imposed by Section 423(b) of
the Code.

          (b)  Any provisions of the Plan to the contrary notwithstanding, no
Employee shall be granted an option under the Plan (i) if, immediately after the
grant, such Employee (or any other person whose stock would be attributed to
such Employee pursuant to Section 424(d) of the Code) would own stock and/or
hold outstanding options to purchase stock possessing five percent (5%) or


                                          2

<PAGE>

more of the total combined voting power or value of all classes of stock of the
Company or of any subsidiary of the Company, or (ii) if such option would permit
his or her rights to purchase stock under all employee stock purchase plans
(described in Section 423 of the Code) of the Company and its Subsidiaries to
accrue at a rate which exceeds Twenty-Five Thousand Dollars ($25,000) of fair
market value of such stock (determined at the time such option is granted) for
each calendar year in which such option is outstanding at any time.

     4.   OFFERING PERIODS.  The Plan shall be implemented by a series of
Offering Periods, with new Offering Periods commencing on or about January 1,
April 1, July 1, and October 1 of each year (or at such other time or times as
may be determined by the Board of Directors).  The first Offering Period shall
commence on the effective date of the Registration Statement on Form S-1 for the
initial public offering of the Company's Common Stock and continue until June
30, 1993.  The Plan shall continue until terminated in accordance with
Section 19 hereof.  The Board of Directors of the Company shall have the power
to change the duration and/or the frequency of Offering Periods with respect to
future offerings without shareholder approval if such change is announced at
least fifteen (15) days prior to the scheduled beginning of the first Offering
Period to be affected.

     5.   PARTICIPATION.

          (a)  An eligible Employee may become a participant in the Plan by
completing a subscription agreement on the form provided by the Company and
filing it with the Company's payroll office prior to the applicable Offering
Date, unless a later time for filing the subscription agreement is set by the
Board for all eligible Employees with respect to a given offering.  The
subscription agreement shall set forth the percentage of the participant's
Compensation (which shall be not less than 1% and not more than 10%) to be paid
as Contributions pursuant to the Plan.

          (b)  Payroll deductions shall commence on the first payroll following
the Offering Date and shall end on the last payroll paid on or prior to the
Exercise Date of the offering to which the subscription agreement is applicable,
unless sooner terminated by the participant as provided in Section 10.

     6.   METHOD OF PAYMENT OF CONTRIBUTIONS.

          (a)  The participant shall elect to have payroll deductions made on
each payday during the Offering Period in an amount not less than one
percent (1%) and not more than ten percent (10%) of such participant's
Compensation on each such payday; provided that the aggregate of such payroll
deductions during the Offering Period shall not exceed ten percent (10%) of the
participant's aggregate Compensation during said Offering Period.  All payroll
deductions made by a participant shall be credited to his or her account under
the Plan.  A participant may not make any additional payments into such account.

          (b)  A participant may discontinue his or her participation in the
Plan as provided in Section 10.  If a participant desires to change the rate of
his or her contributions, he or she may do


                                          3

<PAGE>

so effective as of the beginning of the next Offering Period following the date
of filing of a new subscription agreement.

          (c)  Notwithstanding the foregoing, to the extent necessary to comply
with Section 423(b)(8) of the Code and Section 3(b) herein, a participant's
payroll deductions may be decreased to 0% at such time during any Offering
Period which is scheduled to end during the current calendar year that the
aggregate of all payroll deductions accumulated with respect to such Offering
Period and any other Offering Period ending within the same calendar year equal
$25,000.  Payroll deductions shall re-commence at the rate provided in such
participant's subscription Agreement at the beginning of the first Offering
Period which is scheduled to end in the following calendar year, unless
terminated by the participant as provided in Section 10.

     7.   GRANT OF OPTION.

          (a)  On the Offering Date of each Offering Period, each eligible
Employee participating in such Offering Period shall be granted an option to
purchase on the Exercise Date a number of shares of the Company's Common Stock
determined by dividing such Employee's Contributions accumulated prior to such
Exercise Date and retained in the participant's account as of the Exercise Date
by the lower of (i) eighty-five percent (85%) of the fair market value of a
share of the Company's Common Stock on the Offering Date, or (ii) eighty-five
percent (85%) of the fair market value of a share of the Company's Common Stock
on the Exercise Date; provided however, that the maximum number of shares an
Employee may purchase during each Offering Period shall be determined at the
Offering Date by dividing $6,250 by the fair market value of a share of the
Company's Common Stock on the Offering Date, and provided further that such
purchase shall be subject to the limitations set forth in Sections 3(b) and 12.
The fair market value of a share of the Company's Common Stock shall be
determined as provided in Section 7(b).

          (b)  The option price per share of the shares offered in a given
Offering Period shall be the lower of:  (i) 85% of the fair market value of a
share of the Common Stock of the Company on the Offering Date; or (ii) 85% of
the fair market value of a share of the Common Stock of the Company on the
Exercise Date.  The fair market value of the Company's Common Stock on a given
date shall be determined by the Board in its discretion based on the closing
price of the Common Stock for such date (or, in the event that the Common Stock
is not traded on such date, on the immediately preceding trading date), as
reported by the National Association of Securities Dealers Automated Quotation
(NASDAQ) National Market System or, if such price is not reported, the mean of
the bid and asked prices per share of the Common Stock as reported by NASDAQ or,
in the event the Common Stock is listed on a stock exchange, the fair market
value per share shall be the closing price on such exchange on such date (or, in
the event that the Common Stock is not traded on such date, on the immediately
preceding trading date), as reported in THE WALL STREET JOURNAL.  For purposes
of the Offering Date under the first Offering Period under the Plan, the fair
market value of a share of the Common Stock of the Company shall be the Price to
Public as set forth in the final prospectus filed with the Securities and
Exchange Commission pursuant to Rule 424 under the Securities Act of 1933, as
amended.


                                          4

     8.   EXERCISE OF OPTION.  Unless a participant withdraws from the Plan as
provided in paragraph 10, his or her option for the purchase of shares will be
exercised automatically on the Exercise Date of the Offering Period, and the
maximum number of full shares subject to option will be purchased at the
applicable option price with the accumulated Contributions in his or her
account.  The shares purchased upon exercise of an option hereunder shall be
deemed to be transferred to the participant on the Exercise Date.  If the
participant is a Reporting Person, the shares purchased upon exercise of an
option shall not be sold or otherwise transferred by the participant within six
(6) months after the Exercise Date.  During his or her lifetime, a participant's
option to purchase shares hereunder is exercisable only by him or her.

     9.   DELIVERY.  As promptly as practicable after the Exercise Date of each
Offering Period, the Company shall arrange the delivery to each participant, as
appropriate, of a certificate representing the shares purchased upon exercise of
his or her option.  Any cash remaining to the credit of a participant's account
under the Plan after a purchase by him or her of shares at the termination of
each Offering Period, or which is insufficient to purchase a full share of
Common Stock of the Company, shall be returned to said participant.

     10.  WITHDRAWAL; TERMINATION OF EMPLOYMENT.

          (a)  A participant may withdraw all but not less than all the
Contributions credited to his or her account under the Plan at any time prior to
the Exercise Date of the Offering Period by giving written notice to the
Company.  All of the participant's Contributions credited to his or her account
will be paid to him or her promptly after receipt of his or her notice of
withdrawal and his or her option for the current period will be automatically
terminated, and no further Contributions for the purchase of shares will be made
during the Offering Period.

          (b)  Upon termination of the participant's Continuous Status as an
Employee prior to the Exercise Date of the Offering Period for any reason,
including retirement or death, the Contributions credited to his or her account
will be returned to him or her or, in the case of his or her death, to the
person or persons entitled thereto under Section 14, and his or her option will
be automatically terminated.

          (c)  In the event an Employee fails to remain in Continuous Status as
an Employee of the Company for at least twenty (20) hours per week during the
Offering Period in which the employee is a participant, he or she will be deemed
to have elected to withdraw from the Plan and the Contributions credited to his
or her account will be returned to him or her and his or her option terminated.

          (d)  A participant's withdrawal from an offering will not have any
effect upon his or her eligibility to participate in a succeeding offering or in
any similar plan which may hereafter be adopted by the Company.

     11.  INTEREST.  No interest shall accrue on the Contributions of a
participant in the Plan.


                                          5

<PAGE>

     12.  STOCK.

          (a)  The maximum number of shares of the Company's Common Stock which
shall be made available for sale under the Plan shall be 1,400,000 shares,
subject to adjustment upon changes in capitalization of the Company as provided
in Section 18.  If the total number of shares which would otherwise be subject
to options granted pursuant to Section 7(a) on the Offering Date of an Offering
Period exceeds the number of shares then available under the Plan (after
deduction of all shares for which options have been exercised or are then
outstanding), the Company shall make a pro rata allocation of the shares
remaining available for option grant in as uniform a manner as shall be
practicable and as it shall determine to be equitable.  In such event, the
Company shall give written notice of such reduction of the number of shares
subject to the option to each Employee affected thereby and shall similarly
reduce the rate of Contributions, if necessary.

          (b)  The participant will have no interest or voting right in shares
covered by his or her option until such option has been exercised.

          (c)  Shares to be delivered to a participant under the Plan will be
registered in the name of the participant or in the name of the participant and
his or her spouse.

     13.  ADMINISTRATION.  The Board, or a committee named by the Board, shall
supervise and administer the Plan and shall have full power to adopt, amend and
rescind any rules deemed desirable and appropriate for the administration of the
Plan and not inconsistent with the Plan, to construe and interpret the Plan, and
to make all other determinations necessary or advisable for the administration
of the Plan.  The composition of the committee shall be in accordance with the
requirements to obtain or retain any available exemption from the operation of
Section 16(b) of the Exchange Act pursuant to Rule 16b-3 promulgated thereunder.

     14.  DESIGNATION OF BENEFICIARY.

          (a)  A participant may file a written designation of a beneficiary who
is to receive any shares and cash, if any, from the participant's account under
the Plan in the event of such participant's death subsequent to the end of the
Offering Period but prior to delivery to him or her of such shares and cash.  In
addition, a participant may file a written designation of a beneficiary who is
to receive any cash from the participant's account under the Plan in the event
of such participant's death prior to the Exercise Date of the Offering Period.
If a participant is married and the designated beneficiary is not the spouse,
spousal consent shall be required for such designation to be effective.

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


                                          6

<PAGE>

the spouse or to any one or more dependents or relatives of the participant, or
if no spouse, dependent or relative is known to the Company, then to such other
person as the Company may designate.

     15.  TRANSFERABILITY.  Neither Contributions credited to a participant's
account nor any rights with regard to the exercise of an option or to receive
shares under the Plan may be assigned, transferred, pledged or otherwise
disposed of in any way (other than by will, the laws of descent and
distribution, or as provided in Section 14) by the participant.  Any such
attempt at assignment, transfer, pledge or other disposition shall be without
effect, except that the Company may treat such act as an election to withdraw
funds in accordance with Section 10.

     16.  USE OF FUNDS.  All Contributions received or held by the Company under
the Plan may be used by the Company for any corporate purpose, and the Company
shall not be obligated to segregate such Contributions.

     17.  REPORTS.  Individual accounts will be maintained for each participant
in the Plan.  Statements of account will be given to participating Employees
promptly following the Exercise Date, which statements will set forth the
amounts of Contributions, the per share purchase price, the number of shares
purchased and the remaining cash balance, if any.

     18.  ADJUSTMENTS UPON CHANGES IN CAPITALIZATION.  Subject to any required
action by the shareholders of the Company, the number of shares of Common Stock
covered by each option under the Plan which has not yet been exercised and the
number of shares of Common Stock which have been authorized for issuance under
the Plan but have not yet been placed under option (collectively, the
"Reserves"), as well as the price per share of Common Stock covered by each
option under the Plan which has not yet been exercised, shall be proportionately
adjusted for any increase or decrease in the number of issued shares of Common
Stock resulting from a stock split, reverse stock split, stock dividend,
combination or reclassification of the Common Stock, or any other increase or
decrease in the number of shares of Common Stock effected without receipt of
consideration by the Company; provided, however, that conversion of any
convertible securities of the Company shall not be deemed to have been "effected
without receipt of consideration".  Such adjustment shall be made by the Board,
whose determination in that respect shall be final, binding and conclusive.
Except as expressly provided herein, no issue by the Company of shares of stock
of any class, or securities convertible into shares of stock of any class, shall
affect, and no adjustment by reason thereof shall be made with respect to, the
number or price of shares of Common Stock subject to an option.

     In the event of the proposed dissolution or liquidation of the Company, the
Offering Period will terminate immediately prior to the consummation of such
proposed action, unless otherwise provided by the Board.  In the event of a
proposed sale of all or substantially all of the assets of the Company, or the
merger of the Company with or into another corporation, each option under the
Plan shall be assumed or an equivalent option shall be substituted by such
successor corporation or a parent or subsidiary of such successor corporation,
unless the Board determines, in the exercise of its sole discretion and in lieu
of such assumption or substitution, to shorten the Offering Period then in
progress by setting a new Exercise Date (the "New Exercise Date").  If the Board
shortens the Offering Period then in progress in lieu of assumption or
substitution in the event of a merger or sale


                                          7

<PAGE>

of assets, the Board shall notify each participant in writing, at least ten (10)
days prior to the New Exercise Date, that the Exercise Date for his or her
option has been changed to the New Exercise Date and that his or her option will
be exercised automatically on the New Exercise Date, unless prior to such date
he or she has withdrawn from the Offering Period as provided in Section 10.  For
purposes of this paragraph, an option granted under the Plan shall be deemed to
be assumed if, following the sale of assets or merger, the option confers the
right to purchase, for each share of option stock subject to the option
immediately prior to the sale of assets or merger, the consideration (whether
stock, cash or other securities or property) received in the sale of assets or
merger by holders of Common Stock for each share of Common Stock held on the
effective date of the transaction (and if such holders were offered a choice of
consideration, the type of consideration chosen by the holders of a majority of
the outstanding shares of Common Stock); provided, however, that if such
consideration received in the sale of assets or merger was not solely common
stock of the successor corporation or its parent (as defined in Section 424(e)
of the Code), the Board may, with the consent of the successor corporation and
the participant, provide for the consideration to be received upon exercise of
the option to be solely common stock of the successor corporation or its parent
equal in fair market value to the per share consideration received by holders of
Common Stock and the sale of assets or merger.

     The Board may, if it so determines in the exercise of its sole discretion,
also make provision for adjusting the Reserves, as well as the price per share
of Common Stock covered by each outstanding option, in the event that the
Company effects one or more reorganizations, recapitalizations, rights offerings
or other increases or reductions of shares of its outstanding Common Stock, and
in the event of the Company being consolidated with or merged into any other
corporation.

     19.  AMENDMENT OR TERMINATION.

          (a)  The Board of Directors of the Company may at any time terminate
or amend the Plan.  Except as provided in Section 18, no such termination may
affect options previously granted, nor may an amendment make any change in any
option theretofore granted which adversely affects the rights of any
participant.  In addition, to the extent necessary to comply with Rule 16b-3
under the Exchange Act, or under Section 423 of the Code (or any successor rule
or provision or any applicable law or regulation), the Company shall obtain
shareholder approval in such a manner and to such a degree as so required.

          (b)  Without shareholder consent and without regard to whether any
participant rights may be considered to have been adversely affected, the Board
(or its committee) shall be entitled to change the Offering Periods, limit the
frequency and/or number of changes in the amount withheld during an Offering
Period, establish the exchange ratio applicable to amounts withheld in a
currency other than U.S. dollars, permit payroll withholding in excess of the
amount designated by a participant in order to adjust for delays or mistakes in
the Company's processing of properly completed withholding elections, establish
reasonable waiting and adjustment periods and/or accounting and crediting
procedures to ensure that amounts applied toward the purchase of Common Stock
for each participant properly correspond with amounts withheld from the
participant's


                                          8

<PAGE>


Compensation, and establish such other limitations or procedures as the Board
(or its committee) determines in its sole discretion advisable which are
consistent with the Plan.

loss.

          I HEREBY AGREE TO NOTIFY THE COMPANY IN WRITING WITHIN 30 DAYS AFTER

received ordinary compensation income at the time of such disposition in an
amount equal to the excess of the fair market value of the shares at the time
such shares were transferred to me over the price which I paid for the shares,

market value at transfer.  The remainder of the gain or loss, if any, recognized

                             CENTURA SOFTWARE CORPORATION

                                1995 STOCK OPTION PLAN

                              (AS AMENDED JUNE 17, 1998)

     1.   PURPOSES OF THE PLAN.   The purposes of this Stock Option Plan are to

for a given day no sales were reported, the closing bid on that day shall be
used), as such price is reported in THE WALL STREET JOURNAL or such other source
as the Administrator deems reliable;

               (ii)   If the Common Stock is quoted on the NASDAQ System (but
not on the National Market thereof) or regularly quoted by a recognized
securities dealer but selling prices are not reported,  its Fair Market Value

Stock, the Fair Market Value thereof shall be determined in good faith by the

having been exercised in full, the unpurchased Shares that were subject thereto
shall, unless the Plan shall have been terminated, become available for future
grant under the Plan. Notwithstanding any other provision of the Plan,  shares
issued under the Plan and later repurchased by the Company shall not become

     4.   ADMINISTRATION OF THE PLAN.

          (a)  COMPOSITION OF ADMINISTRATOR.

               (i)   MULTIPLE ADMINISTRATIVE BODIES.  If permitted by Rule
16b-3,  and by the legal requirements relating to the administration of
incentive stock option plans,  if any, of applicable securities laws and the
Code (collectively, the "Applicable Laws"), the Plan may (but need not) be
administered by different administrative bodies with respect to Directors,
Officers and Employees who are neither Directors nor Officers.


                                       3
<PAGE>

               (ii)   ADMINISTRATION WITH RESPECT TO DIRECTORS AND OFFICERS. 
With respect to grants of Options to Employees or Consultants who are also
Officers or Directors of the Company, the Plan shall be administered by (A) the
Board, if the Board may administer the Plan in compliance with Rule 16b-3 as it
applies to a plan intended to qualify thereunder as a discretionary plan and
Section 162(m) of the Code as it applies so as to qualify grants of Options to
Named Executives as performance-based compensation, or (B) a Committee
designated by the Board to administer the Plan, which Committee shall be
constituted in such a manner as to permit the Plan to comply with Rule 16b-3 as
it applies to a plan intended to qualify thereunder as a discretionary plan, to
qualify grants of Options to Named Executives as performance-based compensation
under Section 162(m) of the Code and to satisfy the Applicable Laws.

               (iii)  ADMINISTRATION WITH RESPECT TO OTHER PERSONS.  With
respect to grants of Options to Employees or Consultants who are neither
Directors nor Officers of the Company, the Plan shall be administered by (A) 
the Board or (B)  a Committee designated by the Board, which Committee shall be
constituted in such a manner as to satisfy the Applicable Laws.

               (iv)  GENERAL.   Once a Committee has been appointed pursuant to
subsection (ii)  or (iii)  of this Section 4(a),  such Committee shall continue
to serve in its designated capacity until otherwise directed by the Board.  From
time to time the Board may increase the size of any Committee and appoint
additional members thereof, remove members (with or without cause) and appoint
new members in substitution therefor, fill vacancies (however caused) and remove
all members of a Committee and thereafter directly administer the Plan, all to
the extent permitted by the Applicable Laws and, in the case of a Committee
appointed under subsection (ii), to the extent permitted by Rule 16b-3 as it
applies to a plan intended to qualify thereunder as a discretionary plan, and to
the extent required under Section 162(m) of the Code to qualify grants of
Options to Named Executives as performance-based compensation.

          (b)  POWERS OF THE ADMINISTRATOR.   Subject to the provisions of the
Plan and in the case of a Committee, the specific duties delegated by the Board
to such Committee, the Administrator shall have the authority, in its
discretion:

               (i)   to determine the Fair Market Value of the Common Stock, in
accordance with Section 2(m) of the Plan;

               (ii)   to select the Employees and Consultants to whom Options
may from time to time be granted hereunder;

               (iii)   to determine whether and to what extent Options are
granted hereunder;

               (iv)   to determine the number of shares of Common Stock to be
covered by each such award granted hereunder;

               (v)   to approve forms of agreement for use under the Plan;


                                       4
<PAGE>

               (vi)   to determine the terms and conditions, not inconsistent
with the terms of the Plan, of any award granted hereunder (including, but not
limited to, the share price and any restriction or limitation, or any vesting
acceleration or waiver of forfeiture restrictions regarding any Option and/or
the shares of Common Stock relating thereto, based in each case on such factors
as the Administrator shall determine, in its sole discretion);

               (vii)   to determine whether,  to what extent and under what
circumstances Common Stock and other amounts payable with respect to an award
under this Plan shall be deferred either automatically or at the election of the
participant  (including providing for and determining the amount,  if any, of
any deemed earnings on any deferred amount during any deferral period); and

               (viii)   to reduce the exercise price of any Option to the then
current Fair Market Value if the Fair Market Value of the Common Stock covered
by such Option shall have declined since the date the Option was granted;

          (c)  EFFECT OF ADMINISTRATOR'S DECISION.  All decisions,
determinations and interpretations of the Administrator shall be final and
binding on all Optionees and any other holders of any Options.

     5.   ELIGIBILITY.

          (a)  RECIPIENTS OF GRANTS.  Nonstatutory Stock Options may be granted
only to Employees and Consultants.  Incentive Stock Options may be granted only
to Employees.  An Employee or Consultant who has been granted an Option may, if
he or she is otherwise eligible, be granted an additional Option or Options.

          (b)  TYPE OF OPTIONS.  Each Option shall be designated in the written
option agreement as either an Incentive Stock Option or a Nonstatutory Stock
Option.  However, notwithstanding such designations, to the extent that the
aggregate Fair Market Value of shares with respect to which Incentive Stock
Options are exercisable for the first time by an Optionee during any calendar
year (under all plans of the Company or any Parent or Subsidiary)  exceeds
$100,000,  such excess Options shall be treated as Nonstatutory Stock Options. 
For purposes of this Section 5(b), Incentive Stock Options shall be taken into
account in the order in which they were granted, and the Fair Market Value of
the Shares shall be determined as of the time the Option with respect to such
Shares is granted.

          (c)  NO EMPLOYMENT RIGHTS.  The Plan shall not confer upon any
Optionee any right with respect to continuation of employment or consulting
relationship with the Company, nor shall it interfere in any way with his or her
right or the Company's right to terminate his or her employment or consulting
relationship at any time, with or without cause.

     6.   TERM OF PLAN.  The Plan shall become effective upon the earlier to
occur of its adoption by the Board or its approval by the shareholders of the
Company as described in 


                                       5
<PAGE>

Section 20 of the Plan.   It shall continue in effect for a term of ten (10)
years unless sooner terminated under Section 16 of the Plan.

     7.   TERM OF OPTION.  The term of each Option shall be the term stated in
the Option Agreement; provided, however, that in the case of an Incentive Stock
Option, the term shall be no more than ten (10) years from the date of grant
thereof or such shorter term as may be provided in the Option Agreement. 
However, in the case of an Option granted to an Optionee who, at the time the
Option is granted, owns stock representing more than ten percent (10%) of the
voting power of all classes of stock of the Company or any Parent or Subsidiary,
the term of the Option shall be five (5) years from the date of grant thereof or
such shorter term as may be provided in the Option Agreement.

     8.   LIMITATION ON GRANTS TO EMPLOYEES.  Subject to adjustment as provided
in this Plan, the maximum number of Shares which may be subject to Options
granted to any one Employee under this Plan for any fiscal year of the Company
shall be 250,000.

     9.   OPTION EXERCISE PRICE AND CONSIDERATION.

          (a)  EXERCISE PRICE.  The per Share exercise price for the Shares to
be issued pursuant to exercise of an Option shall be such price as is determined
by the Administrator, but shall be subject to the following:

               (i)   In the case of an Incentive Stock Option

                     (A)  granted to an Employee who, at the time of the grant
of such Incentive Stock Option, owns stock representing more than ten percent
(10%) of the voting power of all classes of stock of the Company or any Parent
or Subsidiary, the per Share exercise price shall be no less than 110% of the
Fair Market Value per Share on the date of grant;

                     (B)  granted to any Employee, the per Share exercise price
shall be no less than 100% of the Fair Market Value per Share on the date of
grant.

               (ii)  In the case of a Nonstatutory Stock Option

                     (A)   granted to a person who, at the time of the grant of
such Option, owns stock representing more than ten percent (10%) of the voting
power of all classes of stock of the Company or any Parent or Subsidiary, the
per Share exercise price shall be no less than 110% of the Fair Market Value per
Share on the date of the grant;

                     (B)   granted to a person who, at the time of the grant of

                     (C)   granted to any person other than a Named Executive,
the per Share exercise price shall be no less than 85% of the Fair Market Value
per Share on the date of grant.

          (b)  PERMISSIBLE CONSIDERATION.  The consideration to be paid for the
Shares to be issued upon exercise of an Option, including the method of payment,
shall be determined by the Administrator (and, in the case of an Incentive Stock
Option, shall be determined at the time of grant) and may consist entirely of
(1) cash,  (2) check,  (3) promissory note,  (4) other Shares that (x)  in the
case of Shares acquired upon exercise of an Option either have been owned by the
Optionee for more than six months on the date of surrender or were not acquired,
directly or indirectly, from the Company, and (y) have a Fair Market Value on
the date of surrender equal to the aggregate exercise price of the Shares as to
which said Option shall be exercised,  (5)  authorization from the Company to
retain from the total number of Shares as to which the Option is exercised that
number of Shares having a Fair Market Value on the date of exercise equal to the
exercise price for the total number of Shares as to which the Option is
exercised,  (6) delivery of a properly executed exercise notice together with
irrevocable instructions to a broker to deliver promptly to the Company the
amount of sale or loan proceeds required to pay the exercise price,  (7)
delivery of an irrevocable subscription agreement for the Shares that
irrevocably obligates the option holder to take and pay for the Shares not more
than twelve months after the date of delivery of the subscription agreement, 
(8)  any combination of the foregoing methods of payment, or (9) such other
consideration and method of payment for the issuance of Shares to the extent
permitted under Applicable Laws.  In making its determination as to the type of
consideration to accept, the Administrator shall consider if acceptance of such
consideration may be reasonably expected to benefit the Company.

     10.  EXERCISE OF OPTION.

          (a)   PROCEDURE FOR EXERCISE; RIGHTS AS A SHAREHOLDER.  Any Option
granted hereunder shall be exercisable at such times and under such conditions
as determined by the Administrator, including performance criteria with respect
to the Company and/or the Optionee, and as shall be permissible under the terms
of the Plan.

          An Option may not be exercised for a fraction of a Share.

          An Option shall be deemed to be exercised when written notice of such
exercise has been given to the Company in accordance with the terms of the
Option by the person entitled to exercise the Option and full payment for the
Shares with respect to which the Option is exercised has been received by the
Company. Full payment may, as authorized by the Administrator, consist of any
consideration and method of payment allowable under Section 9(b) of the Plan. 
Until the issuance (as evidenced by the appropriate entry on the books of the
Company or of a duly authorized transfer agent of the Company) of the stock
certificate evidencing such Shares, no right to vote or receive dividends or any
other rights as a shareholder shall exist with respect to the Optioned Stock,
notwithstanding the exercise of the Option.  The Company shall issue (or cause
to be issued) such stock certificate promptly upon exercise of the Option.  No
adjustment 


                                       7
<PAGE>

will be made for a dividend or other right for which the record date is prior to
the date the stock certificate is issued, except as provided in Section 14 of
the Plan.

          Exercise of an Option in any manner shall result in a decrease in the
number of Shares which thereafter may be available, both for purposes of the
Plan and for sale under the Option, by the number of Shares as to which the
Option is exercised.

          (b)   TERMINATION OF STATUS AS AN EMPLOYEE OR CONSULTANT.  In the
event of termination of an Optionee's Continuous Status as an Employee or
Consultant, such Optionee may, but only within thirty (30) days (or such other
period of time, not exceeding three (3) months in the case of an Incentive Stock
Option or six (6) months in the case of a Nonstatutory Stock Option, as is
determined by the Administrator, with such determination in the case of an
Incentive Stock Option being made at the time of grant of the Option) after the
date of such termination (but in no event later than the date of expiration of
the term of such Option as set forth in the Option Agreement), exercise his or
her Option to the extent that he or she was entitled to exercise it at the date
of such termination.  To the extent that the Optionee was not entitled to
exercise the Option at the date of such termination, or if the optionee does not
exercise such Option (which he or she was entitled to exercise) within the time
specified herein, the Option shall terminate.

          (c)   DISABILITY OF OPTIONEE.  Notwithstanding the provisions of
Section 10(b) above, in the event of termination of an Optionee's Continuous
Status as an Employee or Consultant as a result of his or her total and
permanent disability (as defined in Section 22(e)(3) of the Code), he or she
may, but only within six (6) months (or such other period of time not exceeding
twelve (12) months as is determined by the Administrator, with such
determination in the case of an Incentive Stock Option being made at the time of
grant of the Option) from the date of such termination (but in no event later
than the date of expiration of the term of such Option as set forth in the
Option Agreement), exercise his or her Option to the extent he or she was
entitled to exercise it at the date of such termination.  To the extent that he
or she was not entitled to exercise the Option at the date of termination, or if
he does not exercise such Option (which he was entitled to exercise) within the
time specified herein, the Option shall terminate.

          (d)  DEATH OF OPTIONEE.   In the event of the death of an Optionee:

               (i)   during the term of the Option who is at the time of his
death an Employee or Consultant of the Company and who shall have been in
Continuous Status as an Employee or Consultant since the date of grant of the
Option, the Option may be exercised, at any time within six (6) months (or such
other period of time, not exceeding six (6) months, as is determined by the
Administrator, with such determination in the case of an Incentive Stock Option
being made at the time of grant of the Option) following the date of death (but
in no event later than the date of expiration of the term of such Option as set
forth in the Option Agreement), by the Optionee's estate or by a person who
acquired the right to exercise the Option by bequest or inheritance but only to
the extent of the right to exercise that would have accrued had the Optionee
continued living and remained in Continuous Status as an Employee or Consultant 


                                       8
<PAGE>

three (3) months (or such other period of time as is determined by the
Administrator as provided above) after the date of death, subject to the
limitation set forth in Section 5(b); or

               (ii)   within thirty (30) days  (or such other period of time not
exceeding three (3) months as is determined by the Administrator, with such
determination in the case of an Incentive Stock Option being made at the time of
grant of the Option) after the termination of Continuous Status as an Employee
or Consultant, the Option may be exercised, at any time within six (6) months
following the date of death (but in no event later than the date of expiration
of the term of such Option as set forth in the Option Agreement), by the
Optionee's estate or by a person who acquired the right to exercise the Option
by bequest or inheritance, but only to the extent of the right to exercise that
had accrued at the date of termination.

          (e)  RULE 16b-3.  Options granted to persons subject to Section 16(b)
of the Exchange Act must comply with Rule 16b-3 and shall contain such
additional conditions or restrictions as may be required thereunder to qualify
for the maximum exemption from Section 16 of the Exchange Act with respect to
Plan transactions.

     11.  WITHHOLDING TAXES.  As a condition to the exercise of Options granted
hereunder, the Optionee shall make such arrangements as the Administrator may
require for the satisfaction of any federal, state, local or foreign withholding
tax obligations that may arise in connection with the exercise, receipt or
vesting of such Option.  The Company shall not be required to issue any Shares
under the Plan until such obligations are satisfied.

     12.  STOCK WITHHOLDING TO SATISFY WITHHOLDING TAX OBLIGATIONS.  At the
discretion of the Administrator, Optionees may satisfy withholding obligations
as provided in this paragraph.  When an Optionee incurs tax liability in
connection with an Option which tax liability is subject to tax withholding
under applicable tax laws, and the Optionee is obligated to pay the Company an
amount required to be withheld under applicable tax laws, the Optionee may
satisfy the withholding tax obligation by one or some combination of the
following methods: (a) by cash payment, or (b) out of Optionee's current
compensation, (c) if permitted by the Administrator, in its discretion, by
surrendering to the Company Shares that (i) in the case of Shares previously
acquired from the Company, have been owned by the Optionee for more than six
months on the date of surrender, and (ii) have a fair market value on the date
of surrender equal to or less than Optionee's marginal tax rate times the
ordinary income recognized, or (d) by electing to have the Company withhold from
the Shares to be issued upon exercise of the Option that number of Shares having
a fair market value equal to the amount required to be withheld.  For this
purpose, the fair market value of the Shares to be withheld shall be determined
on the date that the amount of tax to be withheld is to be determined (the "Tax
Date").

               Any surrender by an Officer or Director of previously owned
Shares to satisfy tax withholding obligations arising upon exercise of this
Option must comply with the applicable provisions of Rule 16b-3 and shall be
subject to such additional conditions or restrictions as may be required
thereunder to qualify for the maximum exemption from Section 16 of the Exchange
Act with respect to Plan transactions.


                                       9
<PAGE>

               All elections by an Optionee to have Shares withheld to satisfy
tax withholding obligations shall be made in writing in a form acceptable to the
Administrator and shall be subject to the following restrictions:

          (a)  the election must be made on or prior to the applicable Tax Date;

          (b)  once made, the election shall be irrevocable as to the particular
Shares of the Option as to which the election is made;

          (c)  all elections shall be subject to the consent or disapproval of
the Administrator;

          (d)  if the Optionee is an Officer or Director, the election must
comply with the applicable provisions of Rule 16b-3 and shall be subject to such
additional conditions or restrictions as may be required thereunder to qualify
for the maximum exemption from Section 16 of the Exchange Act with respect to
Plan transactions.

               In the event the election to have Shares withheld is made by an
Optionee and the Tax Date is deferred under Section 83 of the Code because no
election is filed under Section 83(b) of the Code, the Optionee shall receive
the full number of Shares with respect to which the Option is exercised but such
Optionee shall be unconditionally obligated to tender back to the Company the
proper number of Shares on the Tax Date.

     13.  NON-TRANSFERABILITY OF OPTIONS.   The Option may not be sold, pledged,
assigned, hypothecated, transferred, or disposed of in any manner other than by
will or by the laws of descent or distribution.  The designation of a
beneficiary by an Optionee will not constitute a transfer.  An Option may be
exercised, during the lifetime of the Optionee, only by the Optionee or a
transferee permitted by this Section 13.

     14.  ADJUSTMENTS UPON CHANGES IN CAPITALIZATION; CORPORATE TRANSACTIONS. 

          (a)  ADJUSTMENTS.  Subject to any required action by the shareholders
of the Company, the number of shares of Common Stock covered by each outstanding
Option, the number of shares of Common Stock that have been authorized for
issuance under the Plan but as to which no Options have yet been granted or
which have been returned to the Plan upon cancellation or expiration of an
Option, the maximum number of shares of Common Stock for which Options may be
granted to any employee under Section 8 of the Plan, and the price per share of
Common Stock covered by each such outstanding Option, shall be proportionately
adjusted for any increase or decrease in the number of issued shares of Common
Stock resulting from a stock split, reverse stock split, stock dividend,
combination or reclassification of the Common Stock, or any other increase or
decrease in the number of issued shares of Common Stock effected without receipt
of consideration by the Company; provided, however, that conversion of any
convertible securities of the Company shall not be deemed to have been "effected
without receipt of consideration."  Such adjustment shall be made by the
Administrator, whose determination in that respect shall be final, binding and
conclusive.  Except as expressly 


                                       10
<PAGE>

provided herein, no issuance by the Company of shares of stock of any class, or
securities convertible into shares of stock of any class, shall affect, and no
adjustment by reason thereof shall be made with respect to, the number or price
of shares of Common Stock subject to an Option.

          (b)  CORPORATE TRANSACTIONS.  In the event of the proposed dissolution
or liquidation of the Company, the Option will terminate immediately prior to
the consummation of such proposed action, unless otherwise provided by the
Administrator.  The Administrator may, in the exercise of its sole discretion in
such instances, declare that any Option shall terminate as of a date fixed by
the Administrator and give each Optionee the right to exercise his or her Option
as to all or any part of the Optioned Stock, including Shares as to which the
Option would not otherwise be exercisable.  In the event of a proposed sale of
all or substantially all of the assets of the Company, or the merger of the
Company with or into another corporation, the Option shall be assumed or an
equivalent option shall be substituted by such successor corporation or a parent
or subsidiary of such successor corporation, unless the Administrator
determines, in the exercise of its sole discretion and in lieu of such
assumption or substitution, that the Optionee shall have the right to exercise
the Option as to some or all of the Optioned Stock, including Shares as to which
the Option would not otherwise be exercisable.  If the Administrator makes an
Option exercisable in lieu of assumption or substitution in the event of a
merger or sale of assets, the Administrator shall notify the Optionee that the
Option shall be exercisable for a period of thirty (30) days from the date of
such notice, and the Option will terminate upon the expiration of such period.

     15.  TIME OF GRANTING OPTIONS.  The date of grant of an Option shall,  for
all purposes, be the date on which the Administrator makes the determination
granting such Option or such other date as is determined by the Administrator. 
Notice of the determination shall be given to each Employee or Consultant to
whom an Option is so granted within a reasonable time after the date of such
grant.

     16.  AMENDMENT AND TERMINATION OF THE PLAN.

          (a)  AMENDMENT AND TERMINATION.   The Board may amend or terminate the
Plan from time to time in such respects as the Board may deem advisable;
provided that, the following revisions or amendments shall require approval of
the shareholders of the Company in the manner described in Section 20 of the
Plan:

               (i)   any increase in the number of Shares subject to the Plan,
          other than in connection with an adjustment under Section 14 of the
          Plan;

               (ii)   any change in the designation of the class of persons
          eligible to be granted Options;
          
               (iii)  any change in the limitation on grants to employees as
          described in Section 8 of the Plan or other changes which would
          require shareholder approval 


                                       11
<PAGE>

          to qualify options granted hereunder as performance-based compensation
          under Section 162(m) of the Code; or

               (iv)  if the Company has a class of equity securities registered
          under Section 12 of the Exchange Act at the time of such revision or
          amendment, any material increase in the benefits accruing to
          participants under the Plan.

          (b)  EFFECT OF AMENDMENT OR TERMINATION.  Any such amendment or
termination of the Plan shall not affect Options already granted and such
Options shall remain in full force and effect as if this Plan had not been
amended or terminated, unless mutually agreed otherwise between the Optionee and
the Board, which agreement must be in writing and signed by the Optionee and the
Company.

     17.  CONDITIONS UPON ISSUANCE OF SHARES.  Shares shall not be issued
pursuant to the exercise of an Option unless the exercise of such Option and the
issuance and delivery of such Shares pursuant thereto shall comply with all
relevant provisions of law, including, without limitation, the Securities Act of
1933, as amended, the Exchange Act, the rules and regulations promulgated
thereunder, and the requirements of any stock exchange upon which the Shares may
then be listed, and shall be further subject to the approval of counsel for the
Company with respect to such compliance.  As a condition to the exercise of an
Option, the Company may require the person exercising such Option to represent
and warrant at the time of any such exercise that the Shares are being purchased
only for investment and without any present intention to sell or distribute such
Shares if, in the opinion of counsel for the Company, such a representation is
required by any of the aforementioned relevant provisions of law.

     18.  RESERVATION OF SHARES.   The Company, during the term of this Plan,
will at all times reserve and keep available such number of Shares as shall be
sufficient to satisfy the requirements of the Plan.  The inability of the
Company to obtain authority from any regulatory body having jurisdiction, which
authority is deemed by the Company's counsel to be necessary to the lawful
issuance and sale of any Shares hereunder, shall relieve the Company of any
liability in respect of the failure to issue or sell such Shares as to which
such requisite authority shall not have been obtained.

     19.  OPTION AGREEMENT.   Options shall be evidenced by written option
agreements in such forms as the Board shall approve.

     20.  SHAREHOLDER APPROVAL.  Continuance of the Plan shall be subject to
approval by the shareholders of the Company within twelve (12) months before or
after the date the Plan is adopted.  Such shareholder approval shall be obtained
in the manner and to the degree required under applicable federal and state law
and the rules of any stock exchange and, in particular, shall be solicited
substantially in accordance with Section 14(a) of the Exchange Act and the rules
and regulations promulgated thereunder.

     21.  INFORMATION TO OPTIONEES.   The Company shall provide to each
Optionee, during the period for which such Optionee has one or more Options
outstanding, copies of all annual reports and other information which are
provided to all shareholders of the Company.

II.  AGREEMENT

     1.   GRANT OF OPTION.  The Plan Administrator of the Company hereby grants
to the Optionee named in the Notice of Grant attached as Part I of this
Agreement (the "Optionee"), an option (the "Option") to purchase a number of
Shares as set forth in the Notice of Grant, at the exercise price per share set
forth in the Notice of Grant (the "Exercise Price"), subject to the terms and
conditions of the Plan, which is incorporated herein by reference.  In the event
of a conflict between the terms and conditions of the Plan and the terms and
conditions of this Option Agreement, the terms and conditions of the Plan shall
prevail.

          If designated in the Notice of Grant as an Incentive Stock Option,
this Option is intended to qualify as an Incentive Stock Option under
Section 422 of the Code.

     2.   EXERCISE OF OPTION.

          (a)  RIGHT TO EXERCISE.  This Option is exercisable during its term,
in accordance with the Vesting Schedule set out in the Notice of Grant and the
applicable provisions of the Plan and this Option Agreement.  In the event of
Optionee's death, Disability or other termination of Optionee's employment or
consulting relationship, the exercisability of the Option is governed by the
applicable provisions of the Plan and this Option Agreement.

          (b)  METHOD OF EXERCISE.  This Option is exercisable by delivery of an
exercise notice, in the form attached as Exhibit A (the "Exercise Notice"),
which shall state the election to exercise the Option, the number of Shares in
respect of which the Option is being exercised (the "Exercised Shares"), and
such other representations and agreements as may be required by the Company
pursuant to the provisions of the Plan.  The Exercise Notice shall be signed by
the Optionee and shall be delivered in person or by certified mail to the
Secretary of the Company.  The Exercise Notice shall be accompanied by payment
of the aggregate Exercise Price as to all Exercised Shares.  This Option shall
be deemed to be exercised upon receipt by the Company of such fully executed
Exercise Notice accompanied by such aggregate Exercise Price.

          No Shares shall be issued pursuant to the exercise of this Option
unless such issuance and exercise complies with all relevant provisions of law
and the requirements of any stock exchange or quotation service upon which the
Shares are then listed.  Assuming such compliance, for income tax purposes, the
Exercised Shares shall be considered transferred to the Optionee on the date the
Option is exercised with respect to such Exercised Shares.


                                       2
<PAGE>

     3.   METHOD OF PAYMENT.  Payment of the aggregate Exercise Price shall be
by any of the following, or a combination thereof, at the election of the
Optionee:

          (a)  cash; or

          (b)  check; or

          (c)  delivery of a properly executed exercise notice, together with
such other documentation as the Administrator and the broker, if applicable,
shall require to effect an exercise of the Option and delivery to the Company of
the sale or loan proceeds required to pay the exercise price; or

          (d)  surrender of other Shares which (i) in the case of Shares
acquired upon exercise of an option, have been owned by the Optionee for more
than six (6) months on the date of surrender, and (ii) have a Fair Market Value
on the date of surrender equal to the aggregate Exercise Price of the Exercised
Shares.

     4.   NON-TRANSFERABILITY OF OPTION.  This Option may not be transferred in
any manner otherwise than by will or by the laws of descent or distribution and
may be exercised during the lifetime of Optionee only by the Optionee.  The
terms of the Plan and this Option Agreement shall be binding upon the executors,
administrators, heirs, successors and assigns of the Optionee.

     5.   TERM OF OPTION.  This Option may be exercised only within the term set
out in the Notice of Grant, and may be exercised during such term only in
accordance with the Plan and the terms of this Option Agreement.

     6.   TAX CONSEQUENCES.  Some of the federal and state tax consequences
relation to this Option, as of the date of this Option, are set forth below. 
THIS SUMMARY IS NECESSARILY INCOMPLETE, AND THE TAX LAWS AND REGULATIONS ARE
SUBJECT TO CHANGE.  THE OPTIONEE SHOULD CONSULT A TAX ADVISER BEFORE EXERCISING
THIS OPTION OR DISPOSING OF THE SHARES.

          (a)  EXERCISING THE OPTION.

               (i)   NONQUALIFIED STOCK OPTION ("NSO").  If this Option does
not qualify as an ISO, the Optionee may incur regular federal income tax and
state income tax liability upon exercise.  The Optionee will be treated as
having received compensation income (taxable at ordinary income tax rates) equal
to the excess, if any, of the fair market value of the Exercised Shares on the
date of exercise over their aggregate Exercise Price.  If the Optionee is an
employee, the Company will be required to withhold from his or her compensation
or collect from Optionee and pay to the applicable taxing authorities an amount
equal to a percentage of this compensation income at the time of exercise.


                                       3
<PAGE>

               (ii)  INCENTIVE STOCK OPTION ("ISO)".  If this Option qualifies
as an ISO, the Optionee will have no regular federal income tax or state income
tax liability upon its exercise, although the excess, if any, of the fair market
value of the Exercised Shares on the date of exercise over their aggregate
Exercise Price will be treated as an adjustment to the alternative minimum tax
for federal tax purposes and may subject the Optionee to alternative minimum tax
in the year of exercise.

          (b)  DISPOSITION OF SHARES.

               (i)   NSO.  If the Optionee holds NSO Shares for at least one
year, any gain realized on disposition of the Shares will be treated as
long-term capital gain for federal income tax purposes.

               (ii)  ISO.  If the Optionee holds ISO Shares for at least one
year after exercise AND two years after the grant date, any gain realized on
disposition of the Shares will be treated as long-term capital gain for federal
income tax purposes.  If the Optionee disposes of ISO Shares within one year
after exercise or two years after the grant date, any gain realized on such
disposition will be treated as compensation income (taxable at ordinary income
rates) to the extent of the excess, if any, of the LESSER OF (A) the difference
between the FAIR MARKET VALUE OF THE SHARES ACQUIRED ON THE DATE OF EXERCISE and
the aggregate Exercise Price, or (B) the difference between the SALE PRICE of
such Shares and the aggregate Exercise Price.

          (c)  NOTICE OF DISQUALIFYING DISPOSITION OF ISO SHARES.  If the
Optionee sells or otherwise disposes of any of the Shares acquired pursuant to
an ISO on or before the later of (i) two years after the grant date, or (ii) one
year after the exercise date, the Optionee shall immediately notify the Company
in writing of such disposition.  The Optionee agrees that he or she may be
subject to income tax withholding by the Company on the compensation income

                       (AS AMENDED AND RESTATED JUNE 17, 1998)


     1.   PURPOSES OF THE PLAN.  The purposes of this Amended and Restated
Directors' Stock Option Plan are to attract and retain the best available
personnel for service as Directors of the Company, to provide additional
incentive to the Outside Directors of the Company to serve as Directors, and to
encourage their continued service on the Board.

          All options granted hereunder shall be nonstatutory stock options.

     2.   DEFINITIONS.  As used herein, the following definitions shall apply:

          (a)  "BOARD" shall mean the Board of Directors of the Company.

          (b)  "CODE" shall mean the Internal Revenue Code of 1986, as amended.

          (c)  "COMMON STOCK" shall mean the Common Stock of the Company.

          (d)  "COMPANY" shall mean Centura Software Corporation, a California
corporation.

          (e)  "CONTINUOUS STATUS AS A DIRECTOR" shall mean the absence of any
interruption or termination of service as a Director.

          (f)  "DIRECTOR" shall mean a member of the Board.

          (g)  "EMPLOYEE" shall mean any person, including any officer or
director, employed by the Company or any Parent or Subsidiary of the Company.
The payment of a director's fee by the Company shall not be sufficient in and of
itself to constitute "employment" by the Company.

          (h)  "EXCHANGE ACT" shall mean the Securities Exchange Act of 1934, as
amended.

          (i)  "OPTION" shall mean a stock option granted pursuant to the Plan.
All options shall be nonstatutory stock options (i.e., options that are not
intended to qualify as incentive stock options under Section 422 of the Code).

          (j)  "OPTIONED STOCK" shall mean the Common Stock subject to an
Option.

          (k)  "OPTIONEE" shall mean an Outside Director who receives an Option.


<PAGE>


          (l)  "OUTSIDE DIRECTOR" shall mean a Director who is not an Employee.

          (m)  "PARENT" shall mean a "parent corporation," whether now or
hereafter existing, as defined in Section 424(e) of the Code.

          (n)  "PLAN" shall mean this Amended and Restated 1996 Directors' Stock
Option Plan.

          (o)  "SHARE" shall mean a share of the Common Stock, as adjusted in
accordance with Section 11 of the Plan.

          (p)  "SUBSIDIARY" shall mean a "subsidiary corporation," whether now
or hereafter existing, as defined in Section 424(f) of the Code.

     3.   STOCK SUBJECT TO THE PLAN.  Subject to the provisions of Section 11 of
the Plan, the maximum aggregate number of Shares which may be optioned and sold
under the Plan is 1,000,000 Shares (the "POOL") of Common Stock.  The Shares may
be authorized, but unissued, or reacquired Common Stock.

          If an Option should expire or become unexercisable for any reason
without having been exercised in full, the unpurchased Shares which were subject
thereto shall, unless the Plan shall have been terminated, become available for
future grant under the Plan.  If Shares which were acquired upon exercise of an
Option are subsequently repurchased by the Company, such Shares shall not in any
event be returned to the Plan and shall not become available for future grant
under the Plan.

     4.   ADMINISTRATION OF AND GRANTS OF OPTIONS UNDER THE PLAN.

          (a)  ADMINISTRATOR.  Except as otherwise required herein, the Plan
shall be administered by the Board.

          (b)  PROCEDURE FOR GRANTS.  All grants of Options hereunder shall be
automatic and nondiscretionary and shall be made strictly in accordance with the
following provisions:

               (i)    No person shall have any discretion to select which
Outside Directors shall be granted Options or to determine the number of Shares
to be covered by Options granted to Outside Directors.

               (ii)   Each Outside Director shall be automatically granted an
Option to purchase Shares (each an "OPTION") as follows: (A) with respect to
persons who are Outside Directors on the effective date of this Plan, as
determined in accordance with Section 6 hereof, 50,000 shares on such effective
date (each such grant may also be referred to hereinafter as an "INITIAL
OPTION"); (B) with respect to persons who are Outside Directors on the Amendment
Date of this Plan, as determined in accordance with Section 6 hereof, who were
granted Initial Options, 50,000 shares on such Amendment Date (each such grant
may also be referred to


                                         -2-
<PAGE>

hereinafter as a "SUPPLEMENTAL OPTION"); and (C) with respect to any other
person, 100,000 shares on the date on which such person first becomes an Outside
Director, whether through election by the shareholders of the Company or
appointment by the Board of Directors to fill a vacancy.

               (iii)  Notwithstanding the provisions of subsection (ii) hereof,
in the event that a grant would cause the number of Shares subject to
outstanding Options plus the number of Shares previously purchased upon exercise
of Options to exceed the Pool, then each such automatic grant shall be for that
number of Shares determined by dividing the total number of Shares remaining
available for grant by the number of Outside Directors receiving an Option on
such date on the automatic grant date.  Any further grants shall then be
deferred until such time, if any, as additional Shares become available for
grant under the Plan through action of the shareholders to increase the number
of Shares which may be issued under the Plan or through cancellation or
expiration of Options previously granted hereunder.

               (iv)   Notwithstanding the provisions of subsection (ii) hereof,
any grant of an Option made before the Company has obtained shareholder approval
of the Plan in accordance with Section 17 hereof shall be conditioned upon
obtaining such shareholder approval of the Plan in accordance with Section 17
hereof.

               (v)    The terms of each Option granted hereunder shall be as
follows:

                      (1)     the Option shall be exercisable only while the
Outside Director remains a Director of the Company, except as set forth in
Section 9 hereof;

                      (2)     the exercise price per Share shall be 100% of the
fair market value per Share on the date of grant of the Option, determined in
accordance with Section 8 hereof; and

                      (3)     each Initial Option shall become exercisable in
installments cumulatively as to 1/48th of the Shares subject to the Option on
each of the first forty-eight monthly anniversaries of the date of grant of the
Initial Option; each Supplemental Option and each Option granted to any Outside
Director after the Amendment Date shall become exercisable in installments
cumulatively as to 1/36th of the Shares subject to the Option on each of the
first thirty-six monthly anniversaries of the date of grant of the Option.

          (c)  POWERS OF THE BOARD.  Subject to the provisions and restrictions
of the Plan, the Board shall have the authority, in its discretion:  (i) to
determine, upon review of relevant information and in accordance with
Section 8(b) of the Plan, the fair market value of the Common Stock; (ii) to
determine the exercise price per share of Options to be granted, which exercise
price shall be determined in accordance with Section 8(a) of the Plan; (iii) to
interpret the Plan; (iv) to prescribe, amend and rescind rules and regulations
relating to the Plan; (v) to authorize any person to execute on behalf of the
Company any instrument required to effectuate the grant of an Option previously
granted hereunder; and (vi) to make all other determinations deemed necessary or
advisable for the administration of the Plan.


                                         -3-
<PAGE>

          (d)  EFFECT OF BOARD'S DECISION.  All decisions, determinations and
interpretations of the Board shall be final and binding on all Optionees and any
other holders of any Options granted under the Plan.

          (e)  SUSPENSION OR TERMINATION OF OPTION.  If the President or his or
her designee reasonably believes that an Optionee has committed an act of
misconduct, the President may suspend the Optionee's right to exercise any
option pending a determination by the Board of Directors (excluding the Outside
Director accused of such misconduct).  If the Board of Directors (excluding the
Outside Director accused of such misconduct) determines an Optionee has
committed an act of embezzlement, fraud, dishonesty, nonpayment of an obligation
owed to the Company, breach of fiduciary duty or deliberate disregard of the
Company rules resulting in loss, damage or injury to the Company, or if an
Optionee makes an unauthorized disclosure of any Company trade secret or
confidential information, engages in any conduct constituting unfair
competition, induces any Company customer to breach a contract with the Company
or induces any principal for whom the Company acts as agent to terminate such
agency relationship, neither the Optionee nor his or her estate shall be
entitled to exercise any option whatsoever.  In making such determination, the
Board of Directors (excluding the Outside Director accused of such misconduct)
shall act fairly and shall give the Optionee an opportunity to appear and
present evidence on Optionee's behalf at a hearing before the Board or a
committee of the Board.

     5.   ELIGIBILITY.  Options may be granted only to Outside Directors.  All
Options shall be automatically granted in accordance with the terms set forth in
Section 4(b) hereof.  An Outside Director who has been granted an Option may, if
he or she is otherwise eligible, be granted an additional Option or Options in
accordance with such provisions.

          The Plan shall not confer upon any Optionee any right with respect to
continuation of service as a Director or nomination to serve as a Director, nor
shall it interfere in any way with any rights which the Director or the Company
may have to terminate his or her directorship at any time.

     6.   TERM OF PLAN; EFFECTIVE DATE.  The Plan shall become effective on the
date on which it is adopted by resolution of the Company's Board of Directors.
It shall continue in effect for a term of ten (10) years unless sooner
terminated under Section 13 of the Plan.  The Plan shall be amended and restated
effective as of the date on which a majority of the Company's shareholders shall
have approved proposed amendments to the Plan.  Shareholder approval was
obtained for the amendments incorporated herein on June 17, 1998 (the "AMENDMENT
DATE").

     7.   TERM OF OPTIONS.  The term of each Option shall be ten (10) years from
the date of grant thereof.

     8.   EXERCISE PRICE AND CONSIDERATION.

          (a)  EXERCISE PRICE.  The per Share exercise price for the Shares to
be issued pursuant to exercise of an Option shall be 100% of the fair market
value per Share on the date of grant of the Option.


                                         -4-
<PAGE>

          (b)  FAIR MARKET VALUE.  The fair market value shall be determined by
the Board; PROVIDED, HOWEVER, that where there is a public market for the Common
Stock, the fair market value per Share shall be the mean of the bid and asked
prices of the Common Stock in the over-the-counter market on the day immediately
preceding the date of grant, as reported in THE WALL STREET JOURNAL (or, if not
so reported, as otherwise reported by the National Association of Securities
Dealers Automated Quotation ("Nasdaq") System) or, in the event the Common Stock
is traded on the Nasdaq National Market or listed on a stock exchange, the fair
market value per Share shall be the closing price on such system or exchange on
the day immediately preceding the date of grant of the Option (or, in the event
that the Common Stock is not traded on such date, on the immediately preceding
trading date), as reported in THE WALL STREET JOURNAL.

          (c)  FORM OF CONSIDERATION.  The consideration to be paid for the
Shares to be issued upon exercise of an Option shall consist entirely of cash,
check, other Shares of Common Stock having a fair market value on the date of
surrender equal to the aggregate exercise price of the Shares as to which said
Option shall be exercised (which, if acquired from the Company, shall have been
held for at least six months), or any combination of such methods of payment
and/or any other consideration or method of payment as shall be permitted under
applicable corporate law.

     9.   EXERCISE OF OPTION.

          (a)  PROCEDURE FOR EXERCISE; RIGHTS AS A SHAREHOLDER.  Any Option
granted hereunder shall be exercisable at such times as are set forth in
Section 4(b) hereof; provided, however, that no Options shall be exercisable
prior to shareholder approval of the Plan in accordance with Section 17 hereof
has been obtained.

               An Option may not be exercised for a fraction of a Share.

               An Option shall be deemed to be exercised when written notice of
such exercise has been given to the Company in accordance with the terms of the
Option by the person entitled to exercise the Option and full payment for the
Shares with respect to which the Option is exercised has been received by the
Company.  Full payment may consist of any consideration and method of payment
allowable under Section 8(c) of the Plan.  Until the issuance (as evidenced by
the appropriate entry on the books of the Company or of a duly authorized
transfer agent of the Company) of the stock certificate evidencing such Shares,
no right to vote or receive dividends or any other rights as a shareholder shall
exist with respect to the Optioned Stock, notwithstanding the exercise of the
Option.  A share certificate for the number of Shares so acquired shall be
issued to the Optionee as soon as practicable after exercise of the Option.  No
adjustment will be made for a dividend or other right for which the record date
is prior to the date the stock certificate is issued, except as provided in
Section 11 of the Plan.

               Exercise of an Option in any manner shall result in a decrease in
the number of Shares which thereafter may be available, both for purposes of the
Plan and for sale under the Option, by the number of Shares as to which the
Option is exercised.


                                         -5-
<PAGE>

          (b)  TERMINATION OF STATUS AS A DIRECTOR.  If an Outside Director
ceases to serve as a Director, he or she may, but only within ninety (90) days
after the date he or she ceases to be a Director of the Company, exercise his or
her Option to the extent that he or she was entitled to exercise it at the date
of such termination.  Notwithstanding the foregoing, in no event may the Option
be exercised after its term set forth in Section 7 has expired.  To the extent
that such Outside Director was not entitled to exercise an Option at the date of
such termination, or does not exercise such Option (which he or she was entitled
to exercise) within the time specified herein, the Option shall terminate.

          (c)  DISABILITY OF OPTIONEE.  Notwithstanding Section 9(b) above, in
the event a Director is unable to continue his or her service as a Director with
the Company as a result of his or her total and permanent disability (as defined
in Section 22(e)(3) of the Code), he or she may, but only within six (6) months
(or such other period of time not exceeding twelve (12) months as is determined
by the Board) from the date of such termination, exercise his or her Option to
the extent he or she was entitled to exercise it at the date of such
termination.  Notwithstanding the foregoing, in no event may the Option be
exercised after its term set forth in Section 7 has expired.  To the extent that
he or she was not entitled to exercise the Option at the date of termination, or
if he or she does not exercise such Option (which he or she was entitled to
exercise) within the time specified herein, the Option shall terminate.

          (d)  DEATH OF OPTIONEE.  In the event of the death of an Optionee:

               (i)    During the term of the Option who is, at the time of his
or her death, a Director of the Company and who shall have been in Continuous
Status as a Director since the date of grant of the Option, the Option may be
exercised, at any time within six (6) months following the date of death, by the
Optionee's estate or by a person who acquired the right to exercise the Option
by bequest or inheritance, but only to the extent of the right to exercise that
would have accrued had the Optionee continued living and remained in Continuous
Status as Director for six (6) months (or such lesser period of time as is
determined by the Board) after the date of death.  Notwithstanding the
foregoing, in no event may the Option be exercised after its term set forth in
Section 7 has expired.

               (ii)   Three (3) months after the termination of Continuous
Status as a Director, the Option may be exercised, at any time within six (6)
months following the date of death, by the Optionee's estate or by a person who
acquired the right to exercise the Option by bequest or inheritance, but only to
the extent of the right to exercise that had accrued at the date of termination.
Notwithstanding the foregoing, in no event may the option be exercised after its
term set forth in Section 7 has expired.

     10.  NONTRANSFERABILITY OF OPTIONS.  The Option may not be sold, pledged,
assigned, hypothecated, transferred, or disposed of in any manner other than by
will or by the laws of descent or distribution or pursuant to a qualified
domestic relations order (as defined by the Code or the rules thereunder).  The
designation of a beneficiary by an Optionee does not constitute a transfer.  An
Option may be exercised during the lifetime of an Optionee only by the Optionee
or a transferee permitted by this Section.

     11.  ADJUSTMENTS UPON CHANGES IN CAPITALIZATION; CORPORATE TRANSACTIONS.

          (a)  ADJUSTMENT.  Subject to any required action by the shareholders
of the Company, the number of shares of Common Stock covered by each outstanding
Option, and the number of shares of Common Stock which have been authorized for
issuance under the Plan but as to which no Options have yet been granted or
which have been returned to the Plan upon cancellation or expiration of an
Option, as well as the price per share of Common Stock covered by each such
outstanding Option, shall be proportionately adjusted for any increase or
decrease in the number of issued shares of Common Stock resulting from a stock
split, reverse stock split, stock dividend, combination or reclassification of
the Common Stock, or any other increase or decrease in the number of issued
shares of Common Stock effected without receipt of consideration by the Company;
PROVIDED, HOWEVER, that conversion of any convertible securities of the Company
shall not be deemed to have been "effected without receipt of consideration."
Such adjustment shall be made by the Board, whose determination in that respect
shall be final, binding and conclusive.  Except as expressly provided herein, no
issuance by the Company of shares of stock of any class, or securities
convertible into shares of stock of any class, shall affect, and no adjustment
by reason thereof shall be made with respect to, the number or price of shares
of Common Stock subject to an Option.

          (b)  CORPORATE TRANSACTIONS.  In the event of (i) a dissolution or
liquidation of the Company, (ii) a sale of all or substantially all of the
Company's assets, (iii) a merger or consolidation in which the Company is not
the surviving corporation, or (iv) any other capital reorganization in which
more than fifty percent (50%) of the shares of the Company entitled to vote are
exchanged, the Company shall give to the Eligible Director, at the time of
adoption of the plan for liquidation, dissolution, sale, merger, consolidation
or reorganization, either a reasonable time thereafter within which to exercise
the Option, including Shares as to which the Option would not be otherwise
exercisable, prior to the effectiveness of such liquidation, dissolution, sale,
merger, consolidation or reorganization, at the end of which time the Option
shall terminate, or the right to exercise the Option, including Shares as to
which the Option would not be otherwise exercisable (or receive a substitute
option with comparable terms), as to an equivalent number of shares of stock of
the corporation succeeding the Company or acquiring its business by reason of
such liquidation, dissolution, sale, merger, consolidation or reorganization.

     12.  TIME OF GRANTING OPTIONS.  The date of grant of an Option shall, for
all purposes, be the date determined in accordance with Section 4(b) hereof.
Notice of the determination shall be given to each Outside Director to whom an
Option is so granted within a reasonable time after the date of such grant.

     13.  AMENDMENT AND TERMINATION OF THE PLAN.

          (a)  AMENDMENT AND TERMINATION.  The Board may amend or terminate the
Plan from time to time in such respects as the Board may deem advisable;
PROVIDED THAT, to the extent necessary and desirable to comply with Rule 16b-3
under the Exchange Act (or any other applicable law or regulation), the Company
shall obtain approval of the shareholders of the


                                         -7-
<PAGE>

Company to Plan amendments to the extent and in the manner required by such law
or regulation.  Notwithstanding the foregoing, the provisions set forth in
Section 4 of this Plan (and any other Sections of this Plan that affect the
formula award terms required to be specified in this Plan by Rule 16b-3) shall
not be amended more than once every six months, other than to comport with
changes in the Code, the Employee Retirement Income Security Act of 1974, as
amended, or the rules thereunder.

          (b)  EFFECT OF AMENDMENT OR TERMINATION.  Any such amendment or
termination of the Plan that would impair the rights of any Optionee shall not
affect Options already granted to such Optionee and such Options shall remain in
full force and effect as if this Plan had not been amended or terminated, unless
mutually agreed otherwise between the Optionee and the Board, which agreement
must be in writing and signed by the Optionee and the Company.

          14.  CONDITIONS UPON ISSUANCE OF SHARES.  Shares shall not be issued
pursuant to the exercise of an Option unless the exercise of such Option and the
issuance and delivery of such Shares pursuant thereto shall comply with all
relevant provisions of law, including, without limitation, the Securities Act of
1933, as amended, the Exchange Act, the rules and regulations promulgated
thereunder, state securities laws, and the requirements of any stock exchange
upon which the Shares may then be listed, and shall be further subject to the
approval of counsel for the Company with respect to such compliance. As a
condition to the exercise of an Option, the Company may require the person
exercising such Option to represent and warrant at the time of any such exercise
that the Shares are being purchased only for investment and without any present
intention to sell or distribute such Shares, if, in the opinion of counsel for
the Company, such a representation is required by any of the aforementioned
relevant provisions of law.

     15.  RESERVATION OF SHARES.  The Company, during the term of this Plan,
will at all times reserve and keep available such number of Shares as shall be
sufficient to satisfy the requirements of the Plan.  Inability of the Company to
obtain authority from any regulatory body having jurisdiction, which authority
is deemed by the Company's counsel to be necessary to the lawful issuance and
sale of any Shares hereunder, shall relieve the Company of any liability in
respect of the failure to issue or sell such Shares as to which such requisite
authority shall not have been obtained.

     16.  OPTION AGREEMENT.  Options shall be evidenced by written option
agreements in such form as the Board shall approve.

17.  SHAREHOLDER APPROVAL.  Continuance of the Plan shall be subject to approval
by the shareholders of the Company at or prior to the first annual meeting of
shareholders held subsequent to the granting of an Option hereunder.  If such
shareholder approval is obtained at a duly held shareholders' meeting, it may be
obtained by the affirmative vote of the holders of a majority of the outstanding
shares of the Company present or represented and entitled to vote thereon.  If
such shareholder approval is obtained by written consent, it may be obtained by
the written consent of the holders of a majority of the outstanding shares of
the Company.  Options


                                         -8-

may be granted, but not exercised, before such shareholder approval.

                            CENTURA SOFTWARE CORPORATION

                        NONSTATUTORY STOCK OPTION AGREEMENT



     1.   GRANT OF OPTION.  The Board of Directors of the Company hereby grants
to the Optionee named in the Notice of Stock Option Grant attached as Part I of
this Agreement (the "OPTIONEE"), an option (the "OPTION") to purchase a number
of Shares, as set forth in the Notice of Stock Option Grant, at the exercise
price per share set forth in the Notice of Stock Option Grant (the "EXERCISE
PRICE"'), subject to the terms and conditions of the 1996 Directors' Stock
Option Plan (the "PLAN"), which is incorporated herein by reference.
(Capitalized terms not defined herein shall have the meanings ascribed to such
terms in the Plan.) In the event of a conflict between the terms and conditions
of the Plan and the terms and conditions of this Nonstatutory Stock Option
Agreement, the terms and conditions of the Plan shall prevail.

     2.   EXERCISE OF OPTION.

               (a)    RIGHT TO EXERCISE.  This Option is exercisable during its
term in accordance with the Vesting Schedule set out in the Notice of Stock
Option Grant and the applicable provisions of the Plan and this Nonstatutory
Stock Option Agreement.  In the event of Optionee's death, disability or other
termination of Optionee's employment or consulting relationship, the
exercisability of the Option is governed by the applicable provisions of the
Plan and this Nonstatutory Stock Option Agreement.

               (b)    METHOD OF EXERCISE.  This Option is exercisable by
delivery of an exercise notice, in the form attached as EXHIBIT A (the "EXERCISE
NOTICE"), which shall state the election to exercise the Option, the number of
Shares in respect of which the Option is being exercised (the "EXERCISED
SHARES"), and such other representations and agreements as may be required by
the Company pursuant to the provisions of the Plan.  The Exercise Notice shall
be signed by the Optionee and shall be delivered in person or by certified mail
to the Secretary of the Company.  The Exercise Notice shall be accompanied by
payment of the aggregate Exercise Price as to all Exercised Shares.  This Option
shall be deemed to be exercised upon receipt by the Company of such fully
executed Exercise Notice accompanied by such aggregate Exercise Price.

               No Shares shall be issued pursuant to the exercise of this Option
unless such issuance and exercise complies with all relevant provisions of law
and the requirements of any stock exchange or quotation service upon which the
Shares are then listed.  Assuming such compliance, for income tax purposes the
Exercised Shares shall be considered transferred to the Optionee on the date the
Option is exercised with respect to such Exercised Shares.

     3.   METHOD OF PAYMENT.  Payment of the aggregate Exercise Price shall be
by any of the following, or a combination thereof, at the election of the
Optionee:

               (a)    cash;


<PAGE>


               (b)    check;

               (c)    delivery of a properly executed exercise notice together
with such other documentation as the Administrator and the broker, if
applicable, shall require to effect an exercise of the Option and delivery to
the Company of the sale or loan proceeds required to pay the exercise price; or

               (d)    surrender of other Shares which (i) in the case of Shares
acquired upon exercise of an option, have been owned by the Optionee for more
than six (6) months on the date of surrender, and (ii) have a Fair Market Value
on the date of surrender equal to the aggregate Exercise Price of the Exercised
Shares.

     4.   NON-TRANSFERABILITY OF OPTION.  This Option may not be transferred in
any manner otherwise than by will or by the laws of descent or distribution or
pursuant to a domestic relations order (as defined by the Code or the rules
thereunder) and may be exercised during the lifetime of Optionee only by the
Optionee or a transferee permitted by Section 10 of the Plan.  The terms of the
Plan and this Nonstatutory Stock Option Agreement shall be binding upon the
executors, administrators, heirs, successors and assigns of the Optionee.

     5.   TERM OF OPTION.  This Option may be exercised only within the term set
out in the Notice of Stock Option Grant, and may be exercised during such term
only in accordance with the Plan and the terms of this Nonstatutory Stock Option
Agreement.

     6.   TAX CONSEQUENCES.  Set forth below is a brief summary of certain
federal and California tax consequences relating to this Option under the law in
effect as of the date of grant.  THIS SUMMARY IS NECESSARILY INCOMPLETE, AND THE
TAX LAWS AND REGULATIONS ARE SUBJECT TO CHANGE.  OPTIONEE SHOULD CONSULT HIS OR
HER OWN TAX ADVISER BEFORE EXERCISING THIS OPTION OR DISPOSING OF THE SHARES.

               (a)    EXERCISING THE OPTION.  Since this Option does not
qualify as an incentive stock option under Section 422 of the Code, the Optionee
may incur regular federal and California income tax liability upon exercise.
The Optionee will be treated as having received compensation income (taxable at
ordinary income tax rates) equal to the excess, if any, of the fair market value
of the Exercised Shares on the date of exercise over their aggregate Exercise
Price.

               (b)    DISPOSITION OF SHARES.  If the Optionee holds the Option
Shares for more than one year, gain realized on disposition of the Shares will
be treated as long-term capital gain for federal and California income tax
purposes.

thereof, modify or amend each Option;

               (viii) to accelerate or defer (with the consent of the Optionee)
the exercise date of any Option;

               (ix)   to authorize any person to execute on behalf of the
Company any instrument required to effectuate the grant of an Option previously
granted by the Administrator; and

               (x)    to make all other determinations deemed necessary or
advisable for the administration of the Plan.

               (c)    EFFECT OF ADMINISTRATOR'S DECISION.  All decisions,
determinations and interpretations of the Administrator shall be final and
binding on all Optionees and any other holders of any Options granted under the
Plan.

     5.   ELIGIBILITY.

               (a)    Options may be granted only to Employees and Consultants.
An Employee or Consultant who has been granted an Option may, if Optionee is
otherwise eligible, be granted an additional Option or Options.

               (b)    Each Option shall be designated in the written option
agreement as a Nonstatutory Stock Option.

               (c)    The Plan shall not confer upon any Optionee any right
with respect to continuation of employment or consulting relationship with the
Company, nor shall it interfere in any way with Optionee's right or the
Company's right to terminate Optionee's employment or consulting relationship at
any time, with or without cause.

     6.   TERM OF PLAN.  The Plan shall become effective upon its adoption by
the Board of Directors.  It shall continue in effect for a term of ten (10)
years unless sooner terminated under Section 14 of the Plan.

     7.   TERM OF OPTION. The term of each Nonstatutory Stock Option shall be
ten (10) years from the date of grant thereof or such shorter term as may be
provided in the Nonstatutory Stock Option Agreement.

     8.   EXERCISE PRICE AND CONSIDERATION.

               (a)    The per Share exercise price for the Shares to be issued
pursuant to exercise of an Option shall be such price as is determined by the
Administrator, but shall be no less than 85% of the fair market value per Share
on the date of grant.

               (b)    The consideration to be paid for the Shares to be issued
upon exercise of an Option, including the method of payment, shall be determined
by the Administrator and may consist entirely of (1) cash, (2) check, (3)
promissory note, (4) other Shares of Common Stock which (i) either have been
owned by the Optionee for more than six (6) months on the date of surrender or
were not acquired, directly or indirectly, from the Company, and (ii) have a
fair market value on the date of surrender equal to the aggregate exercise price
of the Shares as to which said Option shall be exercised, (5) delivery of a
properly executed exercise notice together with irrevocable instructions to a
broker to deliver promptly to the Company the amount of sale or loan proceeds
required to pay the exercise price, or (6) any combination of such methods of
payment.  In making its determination as to the type of consideration to accept,
the Administrator shall consider if acceptance of such consideration may be
reasonably expected to benefit the Company.

     9.   EXERCISE OF OPTION.

               (a)    PROCEDURE FOR EXERCISE; RIGHTS AS A SHAREHOLDER.  Any
Option granted hereunder shall be exercisable at such times and under such
conditions as determined by the Administrator, including performance criteria
with respect to the Company and/or the Optionee, and as shall be permissible
under the terms of the Plan.

               An Option may not be exercised for a fraction of a Share.

               An Option shall be deemed to be exercised when written notice of
such exercise has been given to the Company in accordance with the terms of the
Option by the person entitled to exercise the Option and full payment for the
Shares with respect to which the Option is exercised has been received by the
Company.  Full payment may, as authorized by the Administrator, consist of any
consideration and method of payment allowable under Section 9(b) of the Plan.
Until the issuance (as evidenced by the appropriate entry on the books of the
Company or of a duly authorized transfer agent of the Company) of the stock
certificate evidencing such Shares, no right to vote or receive dividends or any
other rights as a shareholder shall exist with respect to the Optioned Stock,
notwithstanding the exercise of the Option.  The Company shall issue (or cause
to be issued) such stock certificate promptly upon exercise of the


                                         -5-
<PAGE>

Option.  No adjustment will be made for a dividend or other right for which the
record date is prior to the date the stock certificate is issued, except as
provided in Section 11 of the Plan.

               Exercise of an Option in any manner shall result in a decrease in
the number of Shares which thereafter may be available, both for purposes of the
Plan and for sale under the Option, by the number of Shares as to which the
Option is exercised.

               (b)    TERMINATION OF STATUS AS AN EMPLOYEE OR CONSULTANT.  In
the event of termination of an Optionee's Continuous Status as an Employee or
Consultant, such Optionee may, but only within thirty (30) days (or such other
period of time, not exceeding six (6) months, as is determined by the
Administrator) after the date of such termination (but in no event later than
the date of expiration of the term of such Option as set forth in the Option
Agreement), exercise Optionee's Option to the extent that Optionee was entitled
to exercise it at the date of such termination.  To the extent that Optionee was
not entitled to exercise the Option at the date of such termination, or if
Optionee does not exercise such Option (which Optionee was entitled to exercise)
within the time specified herein, the Option shall terminate.

               (c)    DISABILITY OF OPTIONEE.  Notwithstanding the provisions
of Section 10(b) above, in the event of termination of an Optionee's Continuous
Status as an Employee or Consultant as a result of Optionee's total and
permanent disability (as defined in Section 22(e)(3) of the Code), Optionee may,
but only within twelve (12) months (but in no event later than the date of
expiration of the term of such Option as set forth in the Option Agreement),
from the date of such termination (but in no event later than the date of
expiration of the term of such Option as set forth in the Option Agreement),
exercise Optionee's Option to the extent Optionee was entitled to exercise it at
the date of such termination.  To the extent that Optionee was not entitled to
exercise the Option at the date of termination, or if Optionee does not exercise
such Option (which Optionee was entitled to exercise) within the time specified
herein, the Option shall terminate.

               (d)    DEATH OF OPTIONEE.  In the event of termination of an
Optionee's Continuance Status as an Employee or Consultant as a result of the
death of an Optionee, the Option may be exercised, at any time within twelve
(12) months following the date of death (but in no event later than the date of
expiration of the term of such Option as set forth in the Option Agreement), by
the Optionee's estate or by a person who acquired the right to exercise the
Option by bequest or inheritance, but only to the extent of the right to
exercise the Option at the date of death.  To the extent that Optionee was not
entitled to exercise the Option at the date of death, or if Optionee does not
exercise such Option to the extent so entitled within the time specified herein,
the Option shall terminate.

     10.  NON-TRANSFERABILITY OF OPTIONS.  The Option may not be sold, pledged,
assigned, hypothecated, transferred, or disposed of in any manner other than by
will or by the laws of descent or distribution; PROVIDED, that the Administrator
may in its discretion grant transferable Nonstatutory Stock Options pursuant to
option agreements specifying (i) the manner in which such Nonstatutory Stock
Options are transferable and (ii) that any such transfer shall be subject to the
Applicable Laws.  The designation of a beneficiary by an Optionee will not
constitute a


                                         -6-
<PAGE>

transfer.  An Option may be exercised, during the lifetime of the Optionee, only
by the Optionee or a transferee permitted by this Section 11.

     11.  ADJUSTMENTS UPON CHANGES IN CAPITALIZATION OR MERGER.

               (a)    ADJUSTMENTS.  Subject to any required action by the
shareholders of the Company, the number of shares of Common Stock covered by
each outstanding Option, and the number of shares of Common Stock which have
been authorized for issuance under the Plan but as to which no Options have yet
been granted or which have been returned to the Plan upon cancellation or
expiration of an Option, and the price per share of Common Stock covered by each
such outstanding Option, shall be proportionately adjusted for any increase or
decrease in the number of issued shares of Common Stock resulting from a stock
split, reverse stock split, stock dividend, combination or reclassification of
the Common Stock, or any other increase or decrease in the number of issued
shares of Common Stock effected without receipt of consideration by the Company;
provided, however, that conversion of any convertible securities of the Company
shall not be deemed to have been "effected without receipt of consideration."
Such adjustment shall be made by the Administrator, whose determination in that
respect shall be final, binding and conclusive.  Except as expressly provided
herein, no issuance by the Company of shares of stock of any class, or
securities convertible into shares of stock of any class, shall affect, and no
adjustment by reason thereof shall be made with respect to, the number or price
of shares of Common Stock subject to an Option.

               (b)    CORPORATE TRANSACTIONS.  In the event of the proposed
dissolution or liquidation of the Company, the Option will terminate immediately
prior to the consummation of such proposed action, unless otherwise provided by
the Administrator.  The Administrator may, in the exercise of its sole
discretion in such instances, declare that any Option shall terminate as of a
date fixed by the Administrator and give each Optionee the right to exercise
Optionee's Option as to all or any part of the Optioned Stock, including Shares
as to which the Option would not otherwise be exercisable.  In the event of a
proposed sale of all or substantially all of the assets of the Company, or the
merger of the Company with or into another corporation, the Option shall be
assumed or an equivalent option shall be substituted by such successor
corporation or a parent or subsidiary of such successor corporation, unless such
successor corporation does not agree to assume the Option or to substitute an
equivalent option, in which case the Administrator shall, in lieu of such
assumption or substitution, provide for the Optionee to have the right to
exercise the Option as to all of the Optioned Stock, including Shares as to
which the Option would not otherwise be exercisable.  If the Administrator makes
an Option fully exercisable in lieu of assumption or substitution in the event
of a merger or sale of assets, the Administrator shall notify the Optionee that
the Option shall be fully exercisable for a period of fifteen (15) days from the
date of such notice, and the Option will terminate upon the expiration of such
period.

     12.  TIME OF GRANTING OPTIONS.  The date of grant of an Option shall, for
all purposes, be the date on which the Administrator makes the determination
granting such Option.  Notice of the determination shall be given to each
Employee or Consultant to whom an Option is so granted within a reasonable time
after the date of such grant.


                                         -7-
<PAGE>

     13.  AMENDMENT AND TERMINATION OF THE PLAN.

               (a)    AMENDMENT AND TERMINATION.  The Board may amend or
terminate the Plan from time to time in such respects as the Board may deem
advisable

               (b)    EFFECT OF AMENDMENT OR TERMINATION.  Any such amendment
or termination of the Plan shall not adversely affect Options already granted
(except to the extent contemplated by such Options) and such Options shall
remain in full force and effect, unless mutually agreed otherwise between the
Optionee and the Board (or other body then administering the Plan), which
agreement must be in writing and signed by the Optionee and the Company.

     14.  CONDITIONS UPON ISSUANCE OF SHARES.  Shares shall not be issued
pursuant to the exercise of an Option unless the exercise of such Option and the
issuance and delivery of such Shares pursuant thereto shall comply with all
relevant provisions of law, including, without limitation, the Securities Act of
1933, as amended, the Exchange Act, the rules and regulations promulgated
thereunder, and the requirements of any stock exchange upon which the Shares may
then be listed, and shall be further subject to the approval of counsel for the
Company with respect to such compliance.

     As a condition to the exercise of an Option, the Company may require the
person exercising such Option to represent and warrant at the time of any such
exercise that the Shares are being purchased only for investment and without any
present intention to sell or distribute such Shares if, in the opinion of
counsel for the Company, such a representation is required by any of the
aforementioned relevant provisions of law.

     15.  RESERVATION OF SHARES.  The Company, during the term of this Plan,
will at all times reserve and keep available such number of Shares as shall be
sufficient to satisfy the requirements of the Plan.  The inability of the
Company to obtain authority from any regulatory body having jurisdiction, which
authority is deemed by the Company's counsel to be necessary to the lawful
issuance and sale of any Shares hereunder, shall relieve the Company of any
liability in respect of the failure to issue or sell such Shares as to which
such requisite authority shall not have been obtained.

     16.  OPTION AGREEMENT.  Options shall be evidenced by written option
agreements in such form as the Administrator shall approve.

     17.  INFORMATION TO OPTIONEES.  The Company shall provide to each Optionee
upon request, during the period for which such Optionee has one or more Options
outstanding, copies of all annual reports and other information which are
provided to all shareholders of the Company.

     18.  WITHHOLDING TAXES.  As a condition to the exercise of Options granted
hereunder, the Optionee shall make such arrangements as the Administrator may
require for the satisfaction of any federal, state, local or foreign withholding
tax obligations that may arise in connection


                                         -8-
<PAGE>

with the exercise, receipt or vesting of such Option.  The Company shall not be
required to issue any Shares under the Plan until such obligations are
satisfied.

     19.  STOCK WITHHOLDING TO SATISFY WITHHOLDING TAX OBLIGATIONS.  At the
discretion of the Administrator, Optionees may satisfy withholding obligations
as provided in this paragraph.  When an Optionee incurs tax liability in
connection with an Option which tax liability is subject to tax withholding
under applicable tax laws, and the Optionee is obligated to pay the Company an
amount required to be withheld under applicable tax laws, the Optionee may
satisfy the withholding tax obligation by one or some combination of the
following methods:  (a) by cash payment, or (b) out of Optionee's current
compensation, or (c) if permitted by the Administrator, in its discretion, by
surrendering to the Company Shares that (i) in the case of Shares previously
acquired from the Company, have been owned by the Optionee for more than six
months on the date of surrender, and (ii) have a fair market value on the date
of surrender equal to or less than Optionee's marginal tax rate times the
ordinary income recognized, or (d) by electing to have the Company withhold from
the Shares to be issued upon exercise of the Option that number of Shares having
a fair market value equal to the amount required to be withheld.  For this
purpose, the fair market value of the Shares to be withheld shall be determined
on the date that the amount of tax to be withheld is to be determined (the "Tax
Date").

          All elections by an Optionee to have Shares withheld to satisfy tax
withholding obligations shall be made in writing in a form acceptable to the
Administrator and shall be subject to the following restrictions:

          (a)  the election must be made on or prior to the applicable Tax Date;

          (b)  once made, the election shall be irrevocable as to the particular
Shares of the Option as to which the election is made; and

          (c)  all elections shall be subject to the consent or disapproval of
the Administrator.

          In the event the election to have Shares withheld is made by an
Optionee and the Tax Date is deferred under Section 83 of the Code because no
election is filed under Section 83(b) of the Code, the Optionee shall receive
the full number of Shares with respect to which the Option is exercised but such
Optionee shall be unconditionally obligated to tender back to the Company the
proper number of Shares on the Tax Date.

                            CENTURA SOFTWARE CORPORATION

                        NONSTATUTORY STOCK OPTION AGREEMENT


     1.   GRANT OF OPTION.  Centura Software Corporation, a California
corporation (the "COMPANY"), hereby grants to the Optionee named in the Notice
of Stock Option Grant attached to this Agreement ("OPTIONEE"), an option (the
"OPTION") to purchase the total number of shares of Common Stock (the "SHARES")
set forth in the Notice of Stock Option Grant, at the exercise price per share
set forth in the Notice of Stock Option Grant (the "EXERCISE PRICE") subject to
the terms, definitions and provisions of this Nonstatutory Stock Option
Agreement (the "Agreement").

          This Option is intended to be a Nonstatutory Stock Option.

     2.   EXERCISE OF OPTION.  This Option shall be exercisable during its term
in accordance with the Vesting Schedule set out in the Notice of Stock Option
Grant as follows:

          (a)  RIGHT TO EXERCISE.

               (i)    This Option may not be exercised for a fraction of a
share.

               (ii)   In the event of Optionee's death, disability or other
termination of employment, the exercisability of the Option is governed by
Sections 6, 7 and 8 below, subject to the limitations contained in paragraph
(iii) below.

               (iii)  In no event may this Option be exercised after the date
of expiration of the term of this Option as set forth in the Notice of Stock
Option Grant.

          (b)  METHOD OF EXERCISE.

               (i)    This Option shall be exercisable by delivering to the
Company a written notice of exercise (in the form attached as EXHIBIT A) which
shall state the election to exercise the Option, the number of Shares in respect
of which the Option is being exercised, and such other representations and
agreements as to the holder's investment intent with respect to such Shares of
Common Stock as may be required by the Company.  Such written notice shall be
signed by Optionee and shall be delivered in person or by certified mail to the
Secretary of the Company.  The written notice shall be accompanied by payment of
the Exercise Price.  This Option shall be deemed to be exercised upon receipt by
the Company of such written notice accompanied by the Exercise Price.

               (ii)   As a condition to the exercise of this Option, Optionee
agrees to make adequate provision for federal, state or other tax withholding
obligations, if any, which arise upon the exercise of the Option or disposition
of Shares, whether by withholding, direct payment to the Company, or otherwise.


<PAGE>


               (iii)  No Shares will be issued pursuant to the exercise of an
Option unless such issuance and such exercise shall comply with all relevant
provisions of law and the requirements of any stock exchange upon which the
Shares may then be listed.  Assuming such compliance, for income tax purposes
the Shares shall be considered transferred to Optionee on the date on which the
Option is exercised with respect to such Shares.

     3.   OPTIONEE'S REPRESENTATIONS.  In the event the Shares purchasable
pursuant to the exercise of this Option have not been registered under the
Securities Act of 1933, as amended (the "SECURITIES ACT"), at the time this
Option is exercised, Optionee shall, if required by the Company, concurrently
with the exercise of all or any portion of this Option, deliver to the Company
an investment representation statement in customary form, a copy of which is
available for Optionee's review from the Company upon request.

     4.   METHOD OF PAYMENT.  Payment of the Exercise Price shall be by any of
the following, or a combination of the following, at the election of Optionee:
(a) cash; (b) check; (c) surrender of other Shares of Common Stock of the
Company that (i) either have been owned by Optionee for more than six (6) months
on the date of surrender or were not acquired, directly or indirectly, from the
Company, and (ii) have a Fair Market Value on the date of surrender equal to the
aggregate exercise price of the Shares as to which said Option shall be
exercised; or (d) if there is a public market for the Shares and they are
registered under the Securities Act, delivery of a properly executed exercise
notice together with irrevocable instructions to a broker to deliver promptly to
the Company the amount of sale or loan proceeds required to pay the exercise
price.

     5.   RESTRICTIONS ON EXERCISE.  This Option may not be exercised if the
issuance of such Shares upon such exercise or the method of payment of
consideration for such shares would constitute a violation of any applicable
federal or state securities or other law or regulation, including any rule under
Part 207 of Title 12 of the Code of Federal Regulations ("REGULATION G") as
promulgated by the Federal Reserve Board.  As a condition to the exercise of
this Option, the Company may require Optionee to make any representation and
warranty to the Company as may be required by any applicable law or regulation.

     6.   TERMINATION OF RELATIONSHIP.  In the event of termination of
Optionee's employment or consulting relationship with the Company, Optionee may,
to the extent otherwise so entitled at the date of such termination (the
"TERMINATION DATE"), exercise this Option during the Termination Period set out
in the Notice of Stock Option Grant.  To the extent that Optionee was not
entitled to exercise this Option at the date of such termination, or if Optionee
does not exercise this Option within the time specified in the Notice of Stock
Option Grant, the Option shall terminate.

     7.   DISABILITY OF OPTIONEE.  Notwithstanding the provisions of Section 6
above, in the event of termination of Optionee's employment or consulting
relationship with the Company as a result of total and permanent disability (as
defined in Section 22(e)(3) of the Internal Revenue Code), Optionee may, but
only within five (5) years from the date of termination of such relationship
(but in no event later than the date of expiration of the term of this Option as
set forth in Section 10 below), exercise the Option to the extent otherwise so
entitled at the date of


                                         -2-
<PAGE>

such termination.  To the extent that Optionee was not entitled to exercise the
Option at the date of termination, or if Optionee does not exercise such Option
(to the extent otherwise so entitled) within the time specified in this
Agreement, the Option shall terminate.

     8.   DEATH OF OPTIONEE.  In the event of the death of Optionee:

          (a)  during the term of this Option and while an employee or
consultant of the Company and having been an employee or consultant of the
Company since the date of grant of the Option, the Option may be exercised, at
any time within five (5) years following the date of death (but in no event
later than the date of expiration of the term of this Option as set forth in
Section 10 below), by Optionee's estate or by a person who acquired the right to
exercise the Option by bequest or inheritance, including by an officer of High
Technology Capital Management, but only to the extent of the right to exercise
that would have accrued had Optionee continued living and remained as an
employee of the Company three (3) months after the date of death; or

          (b)  within thirty (30) days after the termination of Optionee's
employment or consulting relationship with the Company, the Option may be
exercised, at any time within five (5) years following the date of death (but in
no event later than the date of expiration of the term of this Option as set
forth in Section 10 below), by Optionee's estate or by a person who acquired the
right to exercise the Option by bequest or inheritance, but only to the extent
of the right to exercise that had accrued at the date of termination.

     9.   NON-TRANSFERABILITY OF OPTION.  This Option may not be transferred in
any manner otherwise than by will or by the laws of descent or distribution.
The designation of a beneficiary does not constitute a transfer.  An Option may
be exercised during the lifetime of Optionee only by Optionee or a transferee
permitted by this section.  The terms of this Option shall be binding upon the
executors, administrators, heirs, successors and assigns of Optionee.

     10.  TERM OF OPTION.  This Option may be exercised only within the term set
out in the Notice of Stock Option Grant, and may be exercised during such term
only in accordance with the terms of this Option.

     11.  NO ADDITIONAL EMPLOYMENT RIGHTS.  Optionee understands and agrees that
the vesting of Shares pursuant to the Vesting Schedule is earned only by
continuing as an employee or consultant of the Company at the will of the
Company (not through the act of being hired, being granted this Option or
acquiring Shares under this Agreement).  Optionee further acknowledges and
agrees that nothing in this Agreement shall confer upon Optionee any right with
respect to continuation as an employee or consultant of the Company, nor shall
it interfere in any way with his or her right or the Company's right to
terminate his or her employment or consulting relationship at any time, with or
without cause.

     12.  TAX CONSEQUENCES.  Optionee acknowledges that he or she has read the
brief summary set forth below of certain federal tax consequences of exercise of
this Option and disposition of the Shares under the law in effect as of the date
of grant.  OPTIONEE UNDERSTANDS THAT THIS SUMMARY IS NECESSARILY INCOMPLETE, AND
THE


                                         -3-
<PAGE>

TAX LAWS AND REGULATIONS ARE SUBJECT TO CHANGE.  OPTIONEE SHOULD CONSULT HIS OR
HER OWN TAX ADVISER BEFORE EXERCISING THIS OPTION OR DISPOSING OF THE SHARES.

          (a)  EXERCISE OF NONSTATUTORY STOCK OPTION.  Optionee may incur
regular federal income tax liability upon the exercise of the Option.  Optionee
will be treated as having received compensation income (taxable at ordinary
income tax rates) equal to the excess, if any, of the fair market value of the
Shares on the date of exercise over the Exercise Price.  In addition, if
Optionee is an employee of the Company, the Company will be required to withhold
from Optionee's compensation or collect from Optionee and pay to the applicable
taxing authorities an amount equal to a percentage of this compensation income
at the time of exercise.

          (b)  DISPOSITION OF SHARES.  Gain realized on the disposition of
Shares will be treated as long-term or short-term capital gain depending on
whether or not the disposition occurs more than one year after the exercise
date.

     13.  SIGNATURE.  This Stock Option Agreement shall be deemed executed by
the Company and Optionee upon execution by such parties of the Notice of Stock
Option Grant attached to this Stock Option Agreement.

                            CENTURA SOFTWARE CORPORATION

                        NONSTATUTORY STOCK OPTION AGREEMENT

     1.   GRANT OF OPTION.  Centura Software Corporation, a California
corporation (the "COMPANY"), hereby grants to the Optionee named in the Notice
of Stock Option Grant attached to this Agreement ("OPTIONEE"), an option (the
"OPTION") to purchase the total number of shares of Common Stock (the "SHARES")
set forth in the Notice of Stock Option Grant, at the exercise price per share
set forth in the Notice of Stock Option Grant (the "EXERCISE PRICE") subject to
the terms, definitions and provisions of this Nonstatutory Stock Option
Agreement (the "Agreement").

          This Option is intended to be a Nonstatutory Stock Option.

     2.   EXERCISE OF OPTION.  This Option shall be exercisable during its term
in accordance with the Vesting Schedule set out in the Notice of Stock Option
Grant as follows:

          (a)  RIGHT TO EXERCISE.

               (i)    This Option may not be exercised for a fraction of a
share.

               (ii)   In the event of Optionee's death, disability or other
termination of employment, the exercisability of the Option is governed by
Sections 6, 7 and 8 below, subject to the limitations contained in paragraph
(iii) below.

               (iii)  In no event may this Option be exercised after the date
of expiration of the term of this Option as set forth in the Notice of Stock
Option Grant.

          (b)  METHOD OF EXERCISE.

               (i)    This Option shall be exercisable by delivering to the
Company a written notice of exercise (in the form attached as EXHIBIT A) which
shall state the election to exercise the Option, the number of Shares in respect
of which the Option is being exercised, and such other representations and
agreements as to the holder's investment intent with respect to such Shares of
Common Stock as may be required by the Company.  Such written notice shall be
signed by Optionee and shall be delivered in person or by certified mail to the
Secretary of the Company.  The written notice shall be accompanied by payment of
the Exercise Price.  This Option shall be deemed to be exercised upon receipt by
the Company of such written notice accompanied by the Exercise Price.

               (ii)   As a condition to the exercise of this Option, Optionee
agrees to make adequate provision for federal, state or other tax withholding
obligations, if any, which arise upon the exercise of the Option or disposition
of Shares, whether by withholding, direct payment to the Company, or otherwise.

<PAGE>

               (iii)  No Shares will be issued pursuant to the exercise of an
Option unless such issuance and such exercise shall comply with all relevant
provisions of law and the requirements of any stock exchange upon which the
Shares may then be listed.  Assuming such compliance, for income tax purposes
the Shares shall be considered transferred to Optionee on the date on which the
Option is exercised with respect to such Shares.

     3.   OPTIONEE'S REPRESENTATIONS.  In the event the Shares purchasable
pursuant to the exercise of this Option have not been registered under the
Securities Act of 1933, as amended (the "SECURITIES ACT"), at the time this
Option is exercised, Optionee shall, if required by the Company, concurrently
with the exercise of all or any portion of this Option, deliver to the Company
an investment representation statement in customary form, a copy of which is
available for Optionee's review from the Company upon request.

     4.   METHOD OF PAYMENT.  Payment of the Exercise Price shall be by any of
the following, or a combination of the following, at the election of Optionee:
(a) cash; (b) check; (c) surrender of other Shares of Common Stock of the
Company that (i) either have been owned by Optionee for more than six (6) months
on the date of surrender or were not acquired, directly or indirectly, from the
Company, and (ii) have a Fair Market Value on the date of surrender equal to the
aggregate exercise price of the Shares as to which said Option shall be
exercised; (d) authorization from the Company to retain from the total number of
Shares as to which the Option is exercised that number of Shares having a Fair
Market value on the date of exercise equal to the exercise price for the total
number of Shares as to which the Option is exercised; or (e) if there is a
public market for the Shares and they are registered under the Securities Act,
delivery of a properly executed exercise notice together with irrevocable
instructions to a broker to deliver promptly to the Company the amount of sale
or loan proceeds required to pay the exercise price.

     5.   RESTRICTIONS ON EXERCISE.  This Option may not be exercised if the
issuance of such Shares upon such exercise or the method of payment of
consideration for such shares would constitute a violation of any applicable
federal or state securities or other law or regulation, including any rule under
Part 207 of Title 12 of the Code of Federal Regulations ("REGULATION G") as
promulgated by the Federal Reserve Board.  As a condition to the exercise of
this Option, the Company may require Optionee to make any representation and
warranty to the Company as may be required by any applicable law or regulation.

     6.   TERMINATION OF RELATIONSHIP.  In the event of termination of
Optionee's employment or consulting relationship with the Company, Optionee may,
to the extent otherwise so entitled at the date of such termination (the
"TERMINATION DATE"), exercise this Option during the Termination Period set out
in the Notice of Stock Option Grant.  To the extent that Optionee was not
entitled to exercise this Option at the date of such termination, or if Optionee
does not exercise this Option within the time specified in the Notice of Stock
Option Grant, the Option shall terminate.

     7.   DISABILITY OF OPTIONEE.  Notwithstanding the provisions of Section 6
above, in the event of termination of Optionee's employment or consulting
relationship with the Company


                                       -2-

<PAGE>

as a result of total and permanent disability (as defined in Section 22(e)(3) of
the Internal Revenue Code), Optionee may, but only within five (5) years from
the date of termination of such relationship (but in no event later than the
date of expiration of the term of this Option as set forth in Section 10 below),
exercise the Option to the extent otherwise so entitled at the date of such
termination.  To the extent that Optionee was not entitled to exercise the
Option at the date of termination, or if Optionee does not exercise such Option
(to the extent otherwise so entitled) within the time specified in this
Agreement, the Option shall terminate.

     8.   DEATH OF OPTIONEE.  In the event of the death of Optionee:

          (a)  during the term of this Option and while an employee or
consultant of the Company and having been an employee or consultant of the
Company since the date of grant of the Option, the Option may be exercised, at
any time within five (5) years following the date of death (but in no event
later than the date of expiration of the term of this Option as set forth in
Section 10 below), by Optionee's estate or by a person who acquired the right to
exercise the Option by bequest or inheritance, including by an officer of High
Technology Capital Management, but only to the extent of the right to exercise
that would have accrued had Optionee continued living and remained as an
employee of the Company three (3) months after the date of death; or

          (b)  within thirty (30) days after the termination of Optionee's
employment or consulting relationship with the Company, the Option may be
exercised, at any time within five (5) years following the date of death (but in
no event later than the date of expiration of the term of this Option as set
forth in Section 10 below), by Optionee's estate or by a person who acquired the
right to exercise the Option by bequest or inheritance, but only to the extent
of the right to exercise that had accrued at the date of termination.

     9.   NON-TRANSFERABILITY OF OPTION.  This Option may not be transferred in
any manner otherwise than by will or by the laws of descent or distribution.
The designation of a beneficiary does not constitute a transfer.  An Option may
be exercised during the lifetime of Optionee only by Optionee or a transferee
permitted by this section.  The terms of this Option shall be binding upon the
executors, administrators, heirs, successors and assigns of Optionee.

     10.  TERM OF OPTION.  This Option may be exercised only within the term set
out in the Notice of Stock Option Grant, and may be exercised during such term
only in accordance with the terms of this Option.

     11.  NO ADDITIONAL EMPLOYMENT RIGHTS.  Optionee understands and agrees that
the vesting of Shares pursuant to the Vesting Schedule is earned only by
continuing as an employee or consultant of the Company at the will of the
Company (not through the act of being hired, being granted this Option or
acquiring Shares under this Agreement).  Optionee further acknowledges and
agrees that nothing in this Agreement shall confer upon Optionee any right with
respect to continuation as an employee or consultant of the Company, nor shall
it interfere in any way with his or her right or the Company's right to
terminate his or her employment or consulting relationship at any time, with or
without cause.

     12.  TAX CONSEQUENCES.  Optionee acknowledges that he or she has read the
brief summary set forth below of certain federal tax consequences of exercise of
this Option and disposition of the Shares under the law in effect as of the date
of grant.  OPTIONEE UNDERSTANDS THAT THIS SUMMARY IS NECESSARILY INCOMPLETE, AND
THE TAX LAWS AND REGULATIONS ARE SUBJECT TO CHANGE.  OPTIONEE SHOULD CONSULT HIS
OR HER OWN TAX ADVISER BEFORE EXERCISING THIS OPTION OR DISPOSING OF THE SHARES.

          (a)  EXERCISE OF NONSTATUTORY STOCK OPTION.  Optionee may incur
regular federal income tax liability upon the exercise of the Option.  Optionee
will be treated as having received compensation income (taxable at ordinary
income tax rates) equal to the excess, if any, of the fair market value of the
Shares on the date of exercise over the Exercise Price.  In addition, if
Optionee is an employee of the Company, the Company will be required to withhold
from Optionee's compensation or collect from Optionee and pay to the applicable
taxing authorities an amount equal to a percentage of this compensation income
at the time of exercise.

          (b)  DISPOSITION OF SHARES.  Gain realized on the disposition of
Shares will be treated as long-term or short-term capital gain depending on
whether or not the disposition occurs more than one year after the exercise
date.

     13.  SIGNATURE.  This Stock Option Agreement shall be deemed executed by
the Company and Optionee upon execution by such parties of the Notice of Stock
Option Grant attached to this Stock Option Agreement.

                            CENTURA SOFTWARE CORPORATION

                        NONSTATUTORY STOCK OPTION AGREEMENT


     1.   GRANT OF OPTION.  Centura Software Corporation, a California
corporation (the "COMPANY"), hereby grants to the Optionee named in the Notice
of Stock Option Grant attached to this Agreement ("OPTIONEE"), an option (the
"OPTION") to purchase the total number of shares of Common Stock (the "SHARES")
set forth in the Notice of Stock Option Grant, at the exercise price per share
set forth in the Notice of Stock Option Grant (the "EXERCISE PRICE") subject to
the terms, definitions and provisions of this Nonstatutory Stock Option
Agreement (the "Agreement").

          This Option is intended to be a Nonstatutory Stock Option.

     2.   EXERCISE OF OPTION.  This Option shall be exercisable during its term
in accordance with the Vesting Schedule set out in the Notice of Stock Option
Grant as follows:

          (a)  RIGHT TO EXERCISE.

               (i)    This Option may not be exercised for a fraction of a
share.

               (ii)   In the event of Optionee's death, disability or other
termination of employment, the exercisability of the Option is governed by
Sections 6, 7 and 8 below, subject to the limitations contained in paragraph
(iii) below.

               (iii)  In no event may this Option be exercised after the date
of expiration of the term of this Option as set forth in the Notice of Stock
Option Grant.

          (b)  METHOD OF EXERCISE.

               (i)    This Option shall be exercisable by delivering to the
Company a written notice of exercise (in the form attached as EXHIBIT A) which
shall state the election to exercise the Option, the number of Shares in respect
of which the Option is being exercised, and such other representations and
agreements as to the holder's investment intent with respect to such Shares of
Common Stock as may be required by the Company.  Such written notice shall be
signed by Optionee and shall be delivered in person or by certified mail to the
Secretary of the Company.  The written notice shall be accompanied by payment of
the Exercise Price.  This Option shall be deemed to be exercised upon receipt by
the Company of such written notice accompanied by the Exercise Price.

               (ii)   As a condition to the exercise of this Option, Optionee
agrees to make adequate provision for federal, state or other tax withholding
obligations, if any, which arise upon the exercise of the Option or disposition
of Shares, whether by withholding, direct payment to the Company, or otherwise.


<PAGE>

               (iii)  No Shares will be issued pursuant to the exercise of an
Option unless such issuance and such exercise shall comply with all relevant
provisions of law and the requirements of any stock exchange upon which the
Shares may then be listed.  Assuming such compliance, for income tax purposes
the Shares shall be considered transferred to Optionee on the date on which the
Option is exercised with respect to such Shares.

     3.   OPTIONEE'S REPRESENTATIONS.  In the event the Shares purchasable
pursuant to the exercise of this Option have not been registered under the
Securities Act of 1933, as amended (the "SECURITIES ACT"), at the time this
Option is exercised, Optionee shall, if required by the Company, concurrently
with the exercise of all or any portion of this Option, deliver to the Company
an investment representation statement in customary form, a copy of which is
available for Optionee's review from the Company upon request.

     4.   METHOD OF PAYMENT.  Payment of the Exercise Price shall be by any of
the following, or a combination of the following, at the election of Optionee:
(a) cash; (b) check; (c) surrender of other Shares of Common Stock of the
Company that (i) either have been owned by Optionee for more than six (6) months
on the date of surrender or were not acquired, directly or indirectly, from the
Company, and (ii) have a Fair Market Value on the date of surrender equal to the
aggregate exercise price of the Shares as to which said Option shall be
exercised; (d) authorization from the Company to retain from the total number of
Shares as to which the Option is exercised that number of Shares having a Fair
Market value on the date of exercise equal to the exercise price for the total
number of Shares as to which the Option is exercised; or (e) if there is a
public market for the Shares and they are registered under the Securities Act,
delivery of a properly executed exercise notice together with irrevocable
instructions to a broker to deliver promptly to the Company the amount of sale
or loan proceeds required to pay the exercise price.

     5.   RESTRICTIONS ON EXERCISE.  This Option may not be exercised if the
issuance of such Shares upon such exercise or the method of payment of
consideration for such shares would constitute a violation of any applicable
federal or state securities or other law or regulation, including any rule under
Part 207 of Title 12 of the Code of Federal Regulations ("REGULATION G") as
promulgated by the Federal Reserve Board.  As a condition to the exercise of
this Option, the Company may require Optionee to make any representation and
warranty to the Company as may be required by any applicable law or regulation.

     6.   TERMINATION OF RELATIONSHIP.  In the event of termination of
Optionee's employment or consulting relationship with the Company, Optionee may,
to the extent otherwise so entitled at the date of such termination (the
"TERMINATION DATE"), exercise this Option during the Termination Period set out
in the Notice of Stock Option Grant.  To the extent that Optionee was not
entitled to exercise this Option at the date of such termination, or if Optionee
does not exercise this Option within the time specified in the Notice of Stock
Option Grant, the Option shall terminate.

     7.   DISABILITY OF OPTIONEE.  Notwithstanding the provisions of Section 6
above, in the event of termination of Optionee's employment or consulting
relationship with the Company


                                         -2-
<PAGE>

as a result of total and permanent disability (as defined in Section 22(e)(3) of
the Internal Revenue Code), Optionee may, but only within five (5) years from
the date of termination of such relationship (but in no event later than the
date of expiration of the term of this Option as set forth in Section 10 below),
exercise the Option to the extent otherwise so entitled at the date of such
termination.  To the extent that Optionee was not entitled to exercise the
Option at the date of termination, or if Optionee does not exercise such Option
(to the extent otherwise so entitled) within the time specified in this
Agreement, the Option shall terminate.

     8.   DEATH OF OPTIONEE.  In the event of the death of Optionee:

          (a)  during the term of this Option and while an employee or
consultant of the Company and having been an employee or consultant of the
Company since the date of grant of the Option, the Option may be exercised, at
any time within five (5) years following the date of death (but in no event
later than the date of expiration of the term of this Option as set forth in
Section 10 below), by Optionee's estate or by a person who acquired the right to
exercise the Option by bequest or inheritance, but only to the extent of the
right to exercise that would have accrued had Optionee continued living and
remained as an employee of the Company three (3) months after the date of death;
or

          (b)  within thirty (30) days after the termination of Optionee's
employment or consulting relationship with the Company, the Option may be
exercised, at any time within five (5) years following the date of death (but in
no event later than the date of expiration of the term of this Option as set
forth in Section 10 below), by Optionee's estate or by a person who acquired the
right to exercise the Option by bequest or inheritance, but only to the extent
of the right to exercise that had accrued at the date of termination.

     9.   NON-TRANSFERABILITY OF OPTION.  This Option may not be transferred in
any manner otherwise than by will or by the laws of descent or distribution.
The designation of a beneficiary does not constitute a transfer.  An Option may
be exercised during the lifetime of Optionee only by Optionee or a transferee
permitted by this section.  The terms of this Option shall be binding upon the
executors, administrators, heirs, successors and assigns of Optionee.

     10.  TERM OF OPTION.  This Option may be exercised only within the term set
out in the Notice of Stock Option Grant, and may be exercised during such term
only in accordance with the terms of this Option.

     11.  NO ADDITIONAL EMPLOYMENT RIGHTS.  Optionee understands and agrees that
the vesting of Shares pursuant to the Vesting Schedule is earned only by
continuing as an employee or consultant of the Company at the will of the
Company (not through the act of being hired, being granted this Option or
acquiring Shares under this Agreement).  Optionee further acknowledges and
agrees that nothing in this Agreement shall confer upon Optionee any right with
respect to continuation as an employee or consultant of the Company, nor shall
it interfere in any way with his or her right or the Company's right to
terminate his or her employment or consulting relationship at any time, with or
without cause.

     12.  TAX CONSEQUENCES.  Optionee acknowledges that he or she has read the
brief summary set forth below of certain federal tax consequences of exercise of
this Option and disposition of the Shares under the law in effect as of the date
of grant.  OPTIONEE UNDERSTANDS THAT THIS SUMMARY IS NECESSARILY INCOMPLETE, AND
THE TAX LAWS AND REGULATIONS ARE SUBJECT TO CHANGE.  OPTIONEE SHOULD CONSULT HIS
OR HER OWN TAX ADVISER BEFORE EXERCISING THIS OPTION OR DISPOSING OF THE SHARES.

          (a)  EXERCISE OF NONSTATUTORY STOCK OPTION.  Optionee may incur
regular federal income tax liability upon the exercise of the Option.  Optionee
will be treated as having received compensation income (taxable at ordinary
income tax rates) equal to the excess, if any, of the fair market value of the
Shares on the date of exercise over the Exercise Price.  In addition, if
Optionee is an employee of the Company, the Company will be required to withhold
from Optionee's compensation or collect from Optionee and pay to the applicable
taxing authorities an amount equal to a percentage of this compensation income
at the time of exercise.

          (b)  DISPOSITION OF SHARES.  Gain realized on the disposition of
Shares will be treated as long-term or short-term capital gain depending on
whether or not the disposition occurs more than one year after the exercise
date.

     13.  SIGNATURE.  This Stock Option Agreement shall be deemed executed by

                            CENTURA SOFTWARE CORPORATION

                        NONSTATUTORY STOCK OPTION AGREEMENT

     1.   GRANT OF OPTION.  Centura Software Corporation, a California
corporation (the "COMPANY"), hereby grants to the Optionee named in the Notice
of Stock Option Grant attached to this Agreement ("OPTIONEE"), an option (the
"OPTION") to purchase the total number of shares of Common Stock (the "SHARES")
set forth in the Notice of Stock Option Grant, at the exercise price per share
set forth in the Notice of Stock Option Grant (the "EXERCISE PRICE") subject to
the terms, definitions and provisions of this Nonstatutory Stock Option
Agreement (the "Agreement").

          This Option is intended to be a Nonstatutory Stock Option.

     2.   EXERCISE OF OPTION.  This Option shall be exercisable during its term
in accordance with the Vesting Schedule set out in the Notice of Stock Option
Grant as follows:

          (a)  RIGHT TO EXERCISE.

               (i)    This Option may not be exercised for a fraction of a
share.

               (ii)   In the event of Optionee's death, disability or other
termination of employment, the exercisability of the Option is governed by
Sections 6, 7 and 8 below, subject to the limitations contained in paragraph
(iii) below.

               (iii)  In no event may this Option be exercised after the date
of expiration of the term of this Option as set forth in the Notice of Stock
Option Grant.

          (b)  METHOD OF EXERCISE.

               (i)    This Option shall be exercisable by delivering to the
Company a written notice of exercise (in the form attached as EXHIBIT A) which
shall state the election to exercise the Option, the number of Shares in respect
of which the Option is being exercised, and such other representations and
agreements as to the holder's investment intent with respect to such Shares of
Common Stock as may be required by the Company.  Such written notice shall be
signed by Optionee and shall be delivered in person or by certified mail to the
Secretary of the Company.  The written notice shall be accompanied by payment of
the Exercise Price.  This Option shall be deemed to be exercised upon receipt by
the Company of such written notice accompanied by the Exercise Price.

               (ii)   As a condition to the exercise of this Option, Optionee
agrees to make adequate provision for federal, state or other tax withholding
obligations, if any, which arise upon the exercise of the Option or disposition
of Shares, whether by withholding, direct payment to the Company, or otherwise.

<PAGE>

               (iii)  No Shares will be issued pursuant to the exercise of an
Option unless such issuance and such exercise shall comply with all relevant
provisions of law and the requirements of any stock exchange upon which the
Shares may then be listed.  Assuming such compliance, for income tax purposes
the Shares shall be considered transferred to Optionee on the date on which the
Option is exercised with respect to such Shares.

     3.   OPTIONEE'S REPRESENTATIONS.  In the event the Shares purchasable
pursuant to the exercise of this Option have not been registered under the
Securities Act of 1933, as amended (the "SECURITIES ACT"), at the time this
Option is exercised, Optionee shall, if required by the Company, concurrently
with the exercise of all or any portion of this Option, deliver to the Company
an investment representation statement in customary form, a copy of which is
available for Optionee's review from the Company upon request.

     4.   METHOD OF PAYMENT.  Payment of the Exercise Price shall be by any of
the following, or a combination of the following, at the election of Optionee:
(a) cash; (b) check; (c) surrender of other Shares of Common Stock of the
Company that (i) either have been owned by Optionee for more than six (6) months
on the date of surrender or were not acquired, directly or indirectly, from the
Company, and (ii) have a Fair Market Value on the date of surrender equal to the
aggregate exercise price of the Shares as to which said Option shall be
exercised; (d) authorization from the Company to retain from the total number of
Shares as to which the Option is exercised that number of Shares having a Fair
Market value on the date of exercise equal to the exercise price for the total
number of Shares as to which the Option is exercised; or (e) if there is a
public market for the Shares and they are registered under the Securities Act,
delivery of a properly executed exercise notice together with irrevocable
instructions to a broker to deliver promptly to the Company the amount of sale
or loan proceeds required to pay the exercise price.

     5.   RESTRICTIONS ON EXERCISE.  This Option may not be exercised if the
issuance of such Shares upon such exercise or the method of payment of
consideration for such shares would constitute a violation of any applicable
federal or state securities or other law or regulation, including any rule under
Part 207 of Title 12 of the Code of Federal Regulations ("REGULATION G") as
promulgated by the Federal Reserve Board.  As a condition to the exercise of
this Option, the Company may require Optionee to make any representation and
warranty to the Company as may be required by any applicable law or regulation.

     6.   TERMINATION OF RELATIONSHIP.  In the event of termination of
Optionee's employment or consulting relationship with the Company, Optionee may,
to the extent otherwise so entitled at the date of such termination (the
"TERMINATION DATE"), exercise this Option during the Termination Period set out
in the Notice of Stock Option Grant.  To the extent that Optionee was not
entitled to exercise this Option at the date of such termination, or if Optionee
does not exercise this Option within the time specified in the Notice of Stock
Option Grant, the Option shall terminate.

     7.   DISABILITY OF OPTIONEE.  Notwithstanding the provisions of Section 6
above, in the event of termination of Optionee's employment or consulting
relationship with the Company


                                         -2-
<PAGE>

as a result of total and permanent disability (as defined in Section 22(e)(3) of
the Internal Revenue Code), Optionee may, but only within five (5) years from
the date of termination of such relationship (but in no event later than the
date of expiration of the term of this Option as set forth in Section 10 below),
exercise the Option to the extent otherwise so entitled at the date of such
termination.  To the extent that Optionee was not entitled to exercise the
Option at the date of termination, or if Optionee does not exercise such Option
(to the extent otherwise so entitled) within the time specified in this
Agreement, the Option shall terminate.

     8.   DEATH OF OPTIONEE.  In the event of the death of Optionee:

          (a)  during the term of this Option and while an employee or
consultant of the Company and having been an employee or consultant of the
Company since the date of grant of the Option, the Option may be exercised, at
any time within five (5) years following the date of death (but in no event
later than the date of expiration of the term of this Option as set forth in
Section 10 below), by Optionee's estate or by a person who acquired the right to
exercise the Option by bequest or inheritance, but only to the extent of the
right to exercise that would have accrued had Optionee continued living and
remained as an employee of the Company three (3) months after the date of death;
or

          (b)  within thirty (30) days after the termination of Optionee's
employment or consulting relationship with the Company, the Option may be
exercised, at any time within five (5) years following the date of death (but in
no event later than the date of expiration of the term of this Option as set
forth in Section 10 below), by Optionee's estate or by a person who acquired the
right to exercise the Option by bequest or inheritance, but only to the extent
of the right to exercise that had accrued at the date of termination.

     9.   NON-TRANSFERABILITY OF OPTION.  This Option may not be transferred in
any manner otherwise than by will or by the laws of descent or distribution.
The designation of a beneficiary does not constitute a transfer.  An Option may
be exercised during the lifetime of Optionee only by Optionee or a transferee
permitted by this section.  The terms of this Option shall be binding upon the
executors, administrators, heirs, successors and assigns of Optionee.

     10.  TERM OF OPTION.  This Option may be exercised only within the term set
out in the Notice of Stock Option Grant, and may be exercised during such term
only in accordance with the terms of this Option.

     11.  NO ADDITIONAL EMPLOYMENT RIGHTS.  Optionee understands and agrees that
the vesting of Shares pursuant to the Vesting Schedule is earned only by
continuing as an employee or consultant of the Company at the will of the
Company (not through the act of being hired, being granted this Option or
acquiring Shares under this Agreement).  Optionee further acknowledges and
agrees that nothing in this Agreement shall confer upon Optionee any right with
respect to continuation as an employee or consultant of the Company, nor shall
it interfere in any way with his or her right or the Company's right to
terminate his or her employment or consulting relationship at any time, with or
without cause.


                                         -3-
<PAGE>

     12.  TAX CONSEQUENCES.  Optionee acknowledges that he or she has read the
brief summary set forth below of certain federal tax consequences of exercise of
this Option and disposition of the Shares under the law in effect as of the date
of grant.  OPTIONEE UNDERSTANDS THAT THIS SUMMARY IS NECESSARILY INCOMPLETE, AND
THE TAX LAWS AND REGULATIONS ARE SUBJECT TO CHANGE.  OPTIONEE SHOULD CONSULT HIS
OR HER OWN TAX ADVISER BEFORE EXERCISING THIS OPTION OR DISPOSING OF THE SHARES.

          (a)  EXERCISE OF NONSTATUTORY STOCK OPTION.  Optionee may incur
regular federal income tax liability upon the exercise of the Option.  Optionee
will be treated as having received compensation income (taxable at ordinary
income tax rates) equal to the excess, if any, of the fair market value of the
Shares on the date of exercise over the Exercise Price.  In addition, if
Optionee is an employee of the Company, the Company will be required to withhold
from Optionee's compensation or collect from Optionee and pay to the applicable
taxing authorities an amount equal to a percentage of this compensation income
at the time of exercise.

          (b)  DISPOSITION OF SHARES.  Gain realized on the disposition of
Shares will be treated as long-term or short-term capital gain depending on
whether or not the disposition occurs more than one year after the exercise
date.

     13.  SIGNATURE.  This Stock Option Agreement shall be deemed executed by
the Company and Optionee upon execution by such parties of the Notice of Stock
Option Grant attached to this Stock Option Agreement.

Ladies and Gentlemen:

     We have examined the Registration Statement on Form S-8 to be filed by you
with the Securities and Exchange Commission on or about October 9, 1998 (the
"Registration Statement") in connection with the registration under the
Securities Act of 1933, as amended, of 1,000,000 shares of your Common Stock
reserved for issuance under the 1992 Employee Stock Purchase Plan, 1,000,000

shares reserved for issuance under the 1997 Nonstatutory Stock Option Plan,
375,000 shares reserved for issuance under the 1997 Nonstatutory Stock Option
Plan and 375,000 shares reserved for issuance under the 1997 Nonstatutory Stock
Option Plan (collectively the "Plans").  As your legal counsel, we have examined
the proceedings taken and are familiar with the proceedings proposed to be taken

Registration Statement and any amendments to it.

                                        Sincerely,
