STOCKHOLDERS' AGREEMENT AND IRREVOCABLE PROXY

This Stockholders' Agreement and Irrevocable Proxy (this "Agreement") is
made and entered into as of January 6, 1997, by and among Centura Software
Corporation, a California corporation ("Acquiror"), InfoSpinner, Inc., a
Delaware corporation ("Target") and the undersigned stockholder (the
"Stockholder") of Target.

RECITALS

A. Concurrently with the execution of this Agreement, Acquiror, Target and
IS Acquisition Corporation ("Merger Sub") are entering into an Agreement and
Plan of Reorganization (the "Reorganization Agreement"), which provides for the
merger (the "Merger") of Merger Sub with and into Target, pursuant to which
Target will become a wholly-owned subsidiary of Acquiror. The Stockholder
understands that Acquiror has undertaken and will continue to undertake
substantial expenses in connection with the negotiation and execution of the
Reorganization Agreement and the subsequent actions necessary to consummate the
Merger and the other transactions contemplated by the Reorganization Agreement.
The Stockholder also understands that in connection with the Merger, the
Stockholder will receive shares of Common Stock, $.01 par value, of Acquiror
(the "Acquiror Shares") in exchange for the shares of Common Stock and Preferred
Stock of Target owned by the Stockholder, in accordance with the provisions of
the Reorganization Agreement.

B. The Stockholder owns the number of issued and outstanding shares of
Common Stock and Preferred Stock, each with a par value of $.001 per share, of
Target as indicated on the final page of this Agreement (as applicable, the
"Common Shares" and the "Preferred Shares" and collectively, the "Shares").

C. The execution of the Reorganization Agreement and the combination of the
businesses of Acquiror and Target will benefit the Stockholder.

AGREEMENT

As an inducement to, and as a condition to Acquiror entering into the
Reorganization Agreement, and in consideration of the expenses incurred and to
be incurred by Acquiror in connection therewith, and for other good and valuable
consideration, the Stockholder and Acquiror agree as follows:

1. AGREEMENT TO VOTE SHARES. During the term of this Agreement, at every
meeting of the stockholders of Target called with respect to any of the
following, and at every adjournment thereof, and on every action or approval by
written consent of the stockholders of Target with respect to any of the
following, the Stockholder agrees to vote the Shares and any shares of capital
stock of Target that Stockholder purchases or with respect to which Stockholder
otherwise acquires beneficial ownership after execution of this Agreement and
prior to the Expiration Date ("New Shares"): (i) in favor of approval of the
Reorganization Agreement and the Merger and any matter that could reasonably be
expected to facilitate the Merger, and (ii) against approval of any proposal
made in opposition to or in competition with consummation of the Merger and
against any merger, consolidation, sale of assets, reorganization or
recapitalization and against any liquidation or winding up of Target (each of
the foregoing is hereinafter referred to as an "Opposing Proposal"). This
Agreement is intended to bind Stockholder only with respect to the specific
matters set forth herein and shall not prohibit Stockholder from acting in
accordance with his or her fiduciary duties, if applicable, as an officer or
director of Target.

2. APPOINTMENT OF PROXY. The Stockholder hereby constitutes and appoints
Xxxxxxx Xxxxxxx ("Proxy Holder"), with full power of substitution, the
Stockholder's true and lawful proxy and attorney-in-fact, to vote the Shares as
indicated in Section 1 hereof at any meeting or in any written consent of the

stockholders of the Company. The Stockholder intends the proxy granted hereby to
be irrevocable and coupled with an interest and will take such further action
and execute such other instruments as may be necessary to effectuate the intent
of this proxy. The Stockholder hereby revokes any proxy previously granted by
the Stockholder with respect to the Shares. During the term of this Agreement,
the Stockholder shall not grant any proxy to any person which conflicts with the
proxy granted herein and any attempt to do so shall be void.

3. VOTING. The Stockholder shall have the right in the first instance to
vote the Shares at any meeting or in any written consent in accordance with the
provisions of Section 1 of this Agreement. In the event that the Stockholder
fails for any reason to vote the Shares in accordance with Section 1, then the
Proxy Holder shall have the right to vote the Shares in accordance with the
provisions of Section 1 pursuant to the provisions of Section 2. The vote of the
Proxy Holder shall control in any conflict between the Proxy Holder's vote of
the Shares and a vote by the Stockholder of the Shares.

4. RESTRICTIONS ON TRANSFERABILITY. The Stockholder will not sell, assign,
transfer or otherwise dispose of (including, without limitation, by the creation
of a Lien (as hereinafter defined)) or permit to be sold, assigned, transferred
or otherwise disposed of any Shares owned by the Stockholder or any Shares the
disposition of which is under the control of the Stockholder, whether such
Shares are owned of record or beneficially by the Stockholder on the date of
this letter agreement or are subsequently acquired, whether pursuant to the
exercise of stock options or otherwise, except (a) for transfers by will or by
operation of law (in which case this letter agreement shall bind the
transferee), (b) for transfers where the transferee agrees in writing to be
bound by the provision of this Agreement and a copy of such agreement by the
transferee is delivered to Acquiror prior to the effectiveness of such transfer
or (c) as Acquiror may otherwise agree in writing. The agreements contained
herein are intended to restrict the transferability of the Shares and to
continue only for such time as may be reasonably necessary to obtain stockholder
and regulatory approval of the Merger and thereafter to consummate the Merger.

5. REPRESENTATIONS, WARRANTIES AND COVENANTS OF THE STOCKHOLDER. The
Stockholder hereby represents, warrants and covenants to Target as follows:

5.1. OWNERSHIP OF SHARES. The Stockholder (i) except as set forth on
the Schedule of Exceptions attached hereto, presently is the sole beneficial and
record owner and holder of the number of the shares of Common Stock and
Preferred Stock of the Target indicated opposite the Stockholder's name on the
last page of this Agreement, free and clear of any liens, claims, charges or
other encumbrances and restrictions of any kind whatsoever arising as a result
of any action or inaction by the Stockholder ("Liens"), and has sole and
unrestricted voting power with respect to such Shares; and (ii) does not own any
shares, or options or warrants or other securities convertible into shares of
capital stock of Target other than the Shares.

5.2. DUE EXECUTION; BINDING AGREEMENT. The Stockholder represents that
the Stockholder has the complete and unrestricted power and the unqualified
right to enter into and perform the terms of this Agreement. The Stockholder
further represents that this Agreement constitutes a valid and binding agreement
with respect to such party, enforceable against such party in accordance with
its terms.

6. ADDITIONAL COVENANTS OF TARGET. Target agrees to take all actions
reasonably deemed by Acquiror to be required to ensure that the rights given to
Acquiror hereunder are effective and that Acquiror enjoys the benefits thereof.
Such actions include, without limitation, the use of Target's best efforts to
cause the Shares to be voted at any meeting or in any written consent in
accordance with the provisions of Section 1 of this Agreement. Target will not,
by any voluntary action, avoid or seek to avoid the observance or performance of
any of the terms to be performed hereunder by Target, nor prevent or seek to
prevent the observance or performance of any of the terms to be performed
hereunder by the Stockholder, but will at all times in good faith assist in the
carrying out of all of the provisions of this Agreement and in the taking of all
actions as may be necessary or appropriate in order to protect the rights of
Acquiror hereunder against impairment.

7. ADDITIONAL DOCUMENTS. The Stockholder hereby covenants and agrees to
execute and deliver any additional documents reasonably deemed by Acquiror to be
necessary or desirable to carry out the intent of this Agreement. 8.Termination.
Notwithstanding anything herein to the contrary, the agreements contained herein

any other remedies that may be available to Target upon any such violation,
Acquiror shall have the right to enforce such covenants and agreements by
