                        CENTURA SOFTWARE CORPORATION
                     1996 DIRECTORS' STOCK OPTION PLAN


     1.   PURPOSES OF THE PLAN.  The purposes of this 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.

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


                                    -1-

<PAGE>

          (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 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 500,000 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 (the "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, and
(B) with respect to any other person, 50,000 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


                                    -2-

<PAGE>


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)  the 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 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.

          (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


                                    -3-

<PAGE>

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.

     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.

          (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.


                                    -4-

<PAGE>

     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.

          (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:


                                    -5-

<PAGE>


     (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


                                    -6-

<PAGE>

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 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.


                                    -7-

<PAGE>

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

                    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;

                                      -3-

          (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.
