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.

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.

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.

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. 11 SECTION 83(b) ELECTION This statement is being made under Section 83(b) of the Internal Revenue Code, pursuant to Treas. Reg. Section 1.83-2. (1) The taxpayer who performed the services is: Name: Address: Taxpayer Ident. No.: (2) The property with respect to which the election is being made is ______ shares of the common stock of Computron Software, Inc. (3) The property was issued on _____________, 199__. (4) The taxable year in which the election is being made is the calendar year 199__. (5) The property is subject to a repurchase right pursuant to which the issuer has the right to acquire the property at the original purchase price if for any reason taxpayer's employment with the issuer is terminated. The issuer's repurchase right lapses in a series of installments over a four (4)-year period ending on__________________ , 199__ . (6) The fair market value at the time of transfer (determined without regard to any restriction other than a restriction which by its terms will never lapse) is $______________________ per share. (7) The amount paid for such property is $____________________ per share. (8) A copy of this statement was furnished to Computron Software, Inc. for whom taxpayer rendered the services underlying the transfer of property. (9) This statement is executed on________________________, 199__. _________________________________________ ____________________________________ Spouse (if any) Taxpayer This election must be filed with the Internal Revenue Service Center with which taxpayer files his or her Federal income tax returns and must be made within 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. 2. 13 APPENDIX The following definitions shall be in effect under the Agreement: A.
