                            COMPUTRON SOFTWARE, INC.
                            STOCK PURCHASE AGREEMENT



                        AGREEMENT made as of this _______ day of ______________
19__, by and between Computron Software, Inc., a Delaware corporation and
__________________________, Optionee under the Corporation's 1995 Stock Option
Plan.

                        All capitalized terms in this Agreement shall have the
meaning assigned to them in this Agreement or in the attached Appendix.

         A.       EXERCISE OF OPTION

                  1.    EXERCISE. Optionee hereby purchases ______________
unvested shares of Common Stock (the "Purchased Shares") pursuant to that
certain option (the "Option") granted Optionee on ____________________, 199__
(the "Grant Date") to purchase up to _______________ shares of Common Stock
under the Plan at the exercise price of $______ per share (the "Exercise
Price").

                  2.    PAYMENT. Concurrently with the delivery of this
Agreement to the Corporation, Optionee shall pay the Exercise Price for the
Purchased Shares in accordance with the provisions of the Option Agreement and
shall deliver whatever additional documents may be required by the Option
Agreement as a condition for exercise, together with a duly-executed blank
Assignment Separate from Certificate (in the form attached hereto as Exhibit I)
with respect to the Purchased Shares.

                  3.    DELIVERY OF CERTIFICATES.  The certificates representing
the Purchased Shares shall be held in escrow in accordance with the provisions
of this Agreement.

                  4.    STOCKHOLDER RIGHTS. Until such time as the Corporation
exercises the Repurchase Right, Optionee (or any successor in interest) shall
have all the rights of a stockholder (including voting, dividend and liquidation
rights) with respect to the Purchased Shares, subject, however, to the transfer
restrictions of Article B.

                  5.    COMPLIANCE WITH LAW. Under no circumstances shall shares
of Common Stock or other assets be issued or delivered to Optionee pursuant to
the provisions of this Agreement unless, in the opinion of counsel for the
Corporation or its successors, there shall have been compliance with all
applicable requirements of the Federal and state securities laws, all applicable
listing requirements of any stock exchange (or the Nasdaq National Market, if
applicable) on which the Common Stock is at the time listed for trading and all
other requirements of law or of any regulatory bodies having jurisdiction over
such issuance and delivery.


   2
         B.       TRANSFER RESTRICTIONS

                  1.    RESTRICTION ON TRANSFER.  Except for any Permitted
Transfer, Optionee shall not transfer, assign, encumber or otherwise dispose of
any of the Purchased Shares which are subject to the Repurchase Right.

                  2.    RESTRICTIVE LEGEND.  The stock certificates for the
Purchased Shares shall be endorsed with the following restrictive legend:

                        "The shares represented by this certificate are unvested
         and are subject to a repurchase right granted to the Corporation and
         accordingly may not be sold, assigned, transferred, encumbered, or in
         any manner disposed of except in conformity with the terms of a written
         agreement dated _____________________, 199_ between the Corporation and
         the registered holder of the shares (or the predecessor in interest to
         the shares). A copy of such agreement is maintained at the
         Corporation's principal corporate offices."

                  3.    TRANSFEREE OBLIGATIONS. Each person (other than the
Corporation) to whom the Purchased Shares are transferred by means of a
Permitted Transfer must, as a condition precedent to the validity of such
transfer, acknowledge in writing to the Corporation that such person is bound by
the provisions of this Agreement and that the transferred shares are subject to
the Repurchase Right to the same extent such shares would be so subject if
retained by Optionee.

         C.       REPURCHASE RIGHT

                  1.    GRANT. The Corporation is hereby granted the right (the
"Repurchase Right"), exercisable at any time during the ninety (90)-day period
following the date Optionee ceases for any reason to remain in Service or (if
later) during the ninety (90)-day period following the execution date of this
Agreement, to repurchase at the Exercise Price all or any portion of the
Purchased Shares in which Optionee is not, at the time of his or her cessation
of Service, vested in accordance with the Vesting Schedule (such shares to be
hereinafter referred to as the "Unvested Shares").

                  2.    EXERCISE OF THE REPURCHASE RIGHT. The Repurchase Right
shall be exercisable by written notice delivered to each Owner of the Unvested
Shares prior to the expiration of the ninety (90)-day exercise period. The
notice shall indicate the number of Unvested Shares to be repurchased and the
date on which the repurchase is to be effected, such date to be not more than
thirty (30) days after the date of such notice. The certificates representing
the Unvested Shares to be repurchased shall be delivered to the Corporation
prior to the close of business on the date specified for the repurchase.
Concurrently with the receipt of such stock certificates, the Corporation shall
pay to Owner, in cash or cash equivalents (including the cancellation of any
purchase-money indebtedness), an amount

                                       2.

   3
equal to the Exercise Price previously paid for the Unvested Shares which are to
be repurchased from Owner.

                  3.    TERMINATION OF THE REPURCHASE RIGHT. The Repurchase
Right shall terminate with respect to any Unvested Shares for which it is not
timely exercised under Paragraph C.2. In addition, the Repurchase Right shall
terminate and cease to be exercisable with respect to any and all Purchased
Shares in which Optionee vests in accordance with the Vesting Schedule.

                  4.    AGGREGATE VESTING LIMITATION. If the Option is exercised
in more than one increment so that Optionee is a party to one or more other
Stock Purchase Agreements (the "Prior Purchase Agreements") which are executed
prior to the date of this Agreement, then the total number of Purchased Shares
as to which Optionee shall be deemed to have a fully-vested interest under this
Agreement and all Prior Purchase Agreements shall not exceed in the aggregate
the number of Purchased Shares in which Optionee would otherwise at the time be
vested, in accordance with the Vesting Schedule, had all the Purchased Shares
(including those acquired under the Prior Purchase Agreements) been acquired
exclusively under this Agreement.

                  5.    RECAPITALIZATION. Any new, substituted or additional
securities or other property (including cash paid other than as a regular cash
dividend) which is by reason of any Recapitalization distributed with respect to
the Purchased Shares shall be immediately subject to the Repurchase Right, but
only to the extent the Purchased Shares are at the time covered by such right.
Appropriate adjustments to reflect such distribution shall be made to the number
and/or class of Purchased Shares subject to this Agreement and to the price per
share to be paid upon the exercise of the Repurchase Right in order to reflect
the effect of any such Recapitalization upon the Corporation's capital
structure; provided, however, that the aggregate purchase price shall remain the
same.

                  6.    CORPORATE TRANSACTION.

                        (a)      Immediately prior to the consummation of any
Corporate Transaction, the Repurchase Right shall automatically lapse in its
entirety, except to the extent the Repurchase Right is to be assigned to the
successor corporation (or parent thereof) in connection with the Corporate
Transaction.

                        (b)      To the extent the Repurchase Right remains in
effect following a Corporate Transaction, such right shall apply to the new
capital stock or other property (including any cash payments) received in
exchange for the Purchased Shares in consummation of the Corporate Transaction,
but only to the extent the Purchased Shares are at the time covered by such
right. Appropriate adjustments shall be made to the price per share payable upon
exercise of the Repurchase Right to reflect the effect of the Corporate
Transaction upon the Corporation's capital structure; provided, however, that
the aggregate purchase price shall remain the same.

                                       3.

   4
                        (c)      The Repurchase Right shall automatically lapse
in its entirety, and all the Purchased Shares shall immediately vest in full,
upon an Involuntary Termination of Optionee's Service within eighteen (18)
months following the effective date of a Corporate Transaction in which the
Repurchase Right has been assigned.

         D.       ESCROW

                  1.    DEPOSIT. Upon issuance, the certificates for the
Purchased Shares shall be deposited in escrow with the Corporation to be held in
accordance with the provisions of this Article D. Each deposited certificate
shall be accompanied by a duly-executed Assignment Separate from Certificate in
the form of Exhibit I. The deposited certificates, together with any other
assets or securities from time to time deposited with the Corporation pursuant
to the requirements of this Agreement, shall remain in escrow until such time or
times as the certificates (or other assets and securities) are to be released or
otherwise surrendered for cancellation in accordance with Paragraph D.3. Upon
delivery of the certificates (or other assets and securities) to the
Corporation, Owner shall be issued a receipt acknowledging the number of
Purchased Shares (or other assets and securities) delivered in escrow.

                  2.    RECAPITALIZATION/REORGANIZATION. Any new, substituted or
additional securities or other property which is by reason of any
Recapitalization or Reorganization distributed with respect to the Purchased
Shares shall be immediately delivered to the Corporation to be held in escrow
under this Article D, but only to the extent the Purchased Shares are at the
time subject to the escrow requirements hereunder. However, all regular cash
dividends on the Purchased Shares (or other securities at the time held in
escrow) shall be paid directly to Owner and shall not be held in escrow.

                  3.    RELEASE/SURRENDER. The Purchased Shares, together with
any other assets or securities held in escrow hereunder, shall be subject to the
following terms relating to their release from escrow or their surrender to the
Corporation for repurchase and cancellation:

                         (i)     Should the Corporation elect to exercise the
         Repurchase Right with respect to any Unvested Shares, then the escrowed
         certificates for those Unvested Shares (together with any other assets
         or securities attributable thereto) shall be surrendered to the
         Corporation concurrently with the payment to Owner of an amount equal
         to the aggregate Exercise Price paid for those Unvested Shares, and
         Owner shall cease to have any further rights or claims with respect to
         such Unvested Shares (or other assets or securities attributable
         thereto).

                        (ii)     Should the Corporation elect not to exercise
         the Repurchase Right with respect to any Unvested Shares held at the
         time in escrow hereunder, then the escrowed certificates for those
         shares (together

                                       4.

   5
         with any other assets or securities attributable thereto) shall be
         released to Owner.

                       (iii)     As the Purchased Shares (or any other assets or
         securities attributable thereto) vest in accordance with the Vesting
         Schedule, the certificates for those vested shares (as well as all
         other vested assets and securities) shall be released from escrow upon
         Owner's request.

                        (iv)     Upon any earlier termination of the Repurchase
         Right in connection with a Corporate Transaction or Involuntary
         Termination, any Purchased Shares (or other assets or securities) at
         the time held in escrow hereunder shall promptly be released to Owner.

         E.       SPECIAL TAX ELECTION

                  The acquisition of the Purchased Shares may result in adverse
tax consequences which may be avoided or mitigated by filing an election under
Code Section 83(b). Such election must be filed within thirty (30) days after
the date of this Agreement. A description of the tax consequences applicable to
the acquisition of the Purchased Shares and the form for making the Code Section
83(b) election are set forth in Exhibit II. OPTIONEE SHOULD CONSULT WITH HIS OR
HER TAX ADVISOR TO DETERMINE THE TAX CONSEQUENCES OF ACQUIRING THE PURCHASED
SHARES AND THE ADVANTAGES AND DISADVANTAGES OF FILING THE CODE SECTION 83(b)
ELECTION. OPTIONEE ACKNOWLEDGES THAT IT IS OPTIONEE'S SOLE RESPONSIBILITY, AND
NOT THE CORPORATION'S, TO FILE A TIMELY ELECTION UNDER CODE SECTION 83(b), EVEN
IF OPTIONEE REQUESTS THE CORPORATION OR ITS REPRESENTATIVES TO MAKE THIS FILING
ON HIS OR HER BEHALF.

         F.       GENERAL PROVISIONS

                  1.    ASSIGNMENT.  The Corporation may assign the Repurchase
Right to any person or entity selected by the Board, including (without
limitation) one or more stockholders of the Corporation.

                  2.    NO EMPLOYMENT OR SERVICE CONTRACT. Nothing in this
Agreement or in the Plan shall confer upon Optionee any right to continue in
Service for any period of specific duration or interfere with or otherwise
restrict in any way the rights of the Corporation (or any Parent or Subsidiary
employing or retaining Optionee) or of Optionee, which rights are hereby
expressly reserved by each, to terminate Optionee's Service at any time for any
reason, with or without cause.

                  3.    NOTICES.  Any notice required to be given under this
Agreement shall be in writing and shall be deemed effective upon personal
delivery or upon deposit in the U.S. mail, registered or certified, postage
prepaid and properly addressed to the party

                                       5.

   6
entitled to such notice at the address indicated below such party's signature
line on this Agreement or at such other address as such party may designate by
ten (10) days advance written notice under this paragraph to all other parties
to this Agreement.

                  4.    NO WAIVER. The failure of the Corporation in any
instance to exercise the Repurchase Right shall not constitute a waiver of any
other repurchase rights that may subsequently arise under the provisions of this
Agreement or any other agreement between the Corporation and Optionee. No waiver
of any breach or condition of this Agreement shall be deemed to be a waiver of
any other or subsequent breach or condition, whether of like or different
nature.

                  5.    CANCELLATION OF SHARES. If the Corporation shall make
available, at the time and place and in the amount and form provided in this
Agreement, the consideration for the Purchased Shares to be repurchased in
accordance with the provisions of this Agreement, then from and after such time,
the person from whom such shares are to be repurchased shall no longer have any
rights as a holder of such shares (other than the right to receive payment of
such consideration in accordance with this Agreement). Such shares shall be
deemed purchased in accordance with the applicable provisions hereof, and the
Corporation shall be deemed the owner and holder of such shares, whether or not
the certificates therefor have been delivered as required by this Agreement.

                  6.    GOVERNING LAW.  This Agreement shall be governed by, and
construed in accordance with, the laws of the State of New Jersey without resort
to that State's conflict-of-laws rules.

                  7.    SUCCESSORS AND ASSIGNS. The provisions of this Agreement
shall inure to the benefit of, and be binding upon, the Corporation and its
successors and assigns and upon Optionee, Optionee's permitted assigns and the
legal representatives, heirs and legatees of Optionee's estate, whether or not
any such person shall have become a party to this Agreement and have agreed in
writing to join herein and be bound by the terms hereof.

                                       6.

   7
                  IN WITNESS WHEREOF, the parties have executed this Agreement
on the day and year first indicated above.

                                   EXHIBIT II

                      FEDERAL INCOME TAX CONSEQUENCES AND
                           SECTION 83(b) TAX ELECTION

         I.       FEDERAL INCOME TAX CONSEQUENCES AND SECTION 83(b) ELECTION FOR
EXERCISE OF NON-STATUTORY OPTION. If the Purchased Shares are acquired pursuant
to the exercise of a Non-Statutory Option, as specified in the Grant Notice,
then under Code Section 83, the excess of the fair market value of the Purchased
Shares on the date any forfeiture restrictions applicable to such shares lapse
over the Exercise Price paid for such shares will be reportable as ordinary
income on the lapse date. For this purpose, the term "forfeiture restrictions"
includes the right of the Corporation to repurchase the Purchased Shares
pursuant to the Repurchase Right. However, Optionee may elect under Code Section
83(b) to be taxed at the time the Purchased Shares are acquired, rather than
when and as such Purchased Shares cease to be subject to such forfeiture
restrictions. Such election must be filed with the Internal Revenue Service
within thirty (30) days after the date of the Agreement. Even if the fair market
value of the Purchased Shares on the date of the Agreement equals the Exercise
Price paid (and thus no tax is payable), the election must be made to avoid
adverse tax consequences in the future. The form for making this election is
attached as part of this exhibit. FAILURE TO MAKE THIS FILING WITHIN THE
APPLICABLE THIRTY (30)-DAY PERIOD WILL RESULT IN THE RECOGNITION OF ORDINARY
INCOME BY OPTIONEE AS THE FORFEITURE RESTRICTIONS LAPSE.

         II.      FEDERAL INCOME TAX CONSEQUENCES AND CONDITIONAL SECTION 83(b)
ELECTION FOR EXERCISE OF INCENTIVE OPTION.  If the Purchased Shares are acquired
pursuant to the exercise of an Incentive Option, as specified in the Grant
Notice, then the following tax principles shall be applicable to the Purchased
Shares:

                        (i)      For regular tax purposes, no taxable income
         will be recognized at the time the Option is exercised.

                        (ii)     The excess of (a) the fair market value of the
         Purchased Shares on the date the Option is exercised or (if later) on
         the date any forfeiture restrictions applicable to the Purchased Shares
         lapse over (b) the Exercise Price paid for the Purchased Shares will be
         includible in Optionee's taxable income for alternative minimum tax
         purposes.

                        (iii)    If Optionee makes a disqualifying disposition
         of the Purchased Shares, then Optionee will recognize ordinary income
         in the year of such disposition equal in amount to the excess of (a)
         the fair market value of the Purchased Shares on the date the Option is
         exercised or (if later) on the date any forfeiture restrictions
         applicable to the Purchased Shares lapse over (b) the Exercise Price
         paid for the Purchased Shares. Any additional gain recognized upon the
         disqualifying disposition will be either short-term or long-term
         capital gain depending upon the period for which the Purchased Shares
         are held prior to the disposition.

                                     II-1.

   10
                        (iv)     For purposes of the foregoing, the term
         "forfeiture restrictions" will include the right of the Corporation to
         repurchase the Purchased Shares pursuant to the Repurchase Right. The
         term "disqualifying disposition" means any sale or other 
         disposition(1/) of the Purchased Shares within two (2) years after 
         the Grant Date or within one (1) year after the exercise date of the 
         Option.

                        (v)      In the absence of final Treasury Regulations
         relating to Incentive Options, it is not certain whether Optionee may,
         in connection with the exercise of the Option for any Purchased Shares
         at the time subject to forfeiture restrictions, file a protective
         election under Code Section 83(b) which would limit (a) Optionee's
         alternative minimum taxable income upon exercise and (b) Optionee's
         ordinary income upon a disqualifying disposition to the excess of the
         fair market value of the Purchased Shares on the date the Option is
         exercised over the Exercise Price paid for the Purchased Shares.
         Accordingly, such election if properly filed will only be allowed to
         the extent the final Treasury Regulations permit such a protective
         election. Page 2 of the attached form for making the election should be
         filed with any election made in connection with the exercise of an
         Incentive Option.

- ------------------
         (1/) Generally, a disposition of shares purchased under an Incentive
Option includes any transfer of legal title, including a transfer by sale,
exchange or gift, but does not include a transfer to the Optionee's spouse, a
transfer into joint ownership with right of survivorship if Optionee remains one
of the joint owners, a pledge, a transfer by bequest or inheritance or certain
tax free exchanges permitted under the Code.

                                     II-2.

thirty (30) days after the execution date of the Stock Purchase Agreement. This
filing should be made by registered or certified mail, return receipt requested.
Optionee must retain two (2) copies of the completed form for filing with his or
her Federal and state tax returns for the current tax year and an additional
copy for his or her records.



   12
The property described in the above Section 83(b) election is comprised of
shares of common stock acquired pursuant to the exercise of an incentive stock
option under Section 422 of the Internal Revenue Code (the "Code"). Accordingly,
it is the intent of the Taxpayer to utilize this election to achieve the
following tax results:

                  1.    The purpose of this election is to have the alternative
minimum taxable income attributable to the purchased shares measured by the
amount by which the fair market value of such shares at the time of their
transfer to the Taxpayer exceeds the purchase price paid for the shares. In the
absence of this election, such alternative minimum taxable income would be
measured by the spread between the fair market value of the purchased shares and
the purchase price which exists on the various lapse dates in effect for the
forfeiture restrictions applicable to such shares. The election is to be
effective to the full extent permitted under the Code.

                  2.    Section 421(a)(1) of the Code expressly excludes from
income any excess of the fair market value of the purchased shares over the
amount paid for such shares. Accordingly, this election is also intended to be
effective in the event there is a "disqualifying disposition" of the shares,
within the meaning of Section 421(b) of the Code, which would otherwise render
the provisions of Section 83(a) of the Code applicable at that time.
Consequently, the Taxpayer hereby elects to have the amount of disqualifying
disposition income measured by the excess of the fair market value of the
purchased shares on the date of transfer to the Taxpayer over the amount paid
for such shares. Since Section 421(a) presently applies to the shares which are
the subject of this Section 83(b) election, no taxable income is actually
recognized for regular tax purposes at this time, and no income taxes are
payable, by the Taxpayer as a result of this election.


THIS PAGE 2 IS TO BE ATTACHED TO ANY SECTION 83(b) ELECTION FILED IN CONNECTION
WITH THE EXERCISE OF AN INCENTIVE STOCK OPTION UNDER THE FEDERAL TAX LAWS.
