All outstanding principal and accrued and unpaid interest shall become due and payable upon the earlier of (i) the consummation of a public offering of the common shares of Payor of more than 1,000,000 shares, (ii) upon transfer of ownership of more than 20% of the outstanding common stock of Payor, or (iii) a sale of substantially all of the assets of Payor.

        Payor shall have the right to prepay all or any part of the unpaid principal amount and accrued interest on this Note without any premium at any time.

        Upon (i) the failure of Payor to make any payment hereunder when due or (ii) the commencement of any bankruptcy, reorganization, arrangement, adjustment of debt, relief of debtors, dissolution, insolvency or liquidation or similar proceeding of any jurisdiction relating to the Payor, the unpaid principal amount and any accrued and unpaid interest hereof shall become immediately due and payable without presentment, demand, protest or notice of any kind in connection with this Note.

        This Note is the note referred to in the Assignment and Assumption Agreement, dated as of July 14, 2000, among Payor and Payee, and is subject to the terms thereof.

        The Payee is hereby authorized to record all loans and advances made by it to the Payor (all of which shall be evidenced by this Note), and all repayments or prepayments thereof, in its books and records, such books and records constituting prima facie evidence of the accuracy of the information contained therein.

        All payments under this Note shall be made without offset, counterclaim or deduction of any kind.

THIS NOTE SHALL BE CONSTRUED IN ACCORDANCE WITH AND GOVERNED BY THE LAW OF THE STATE OF NEW YORK.

EXHIBIT A
TO AMENDMENT NUMBER TWO TO PROMISSORY NOTE

        FOR VALUE RECEIVED, ACCPAC International, Inc., a Delaware corporation (the "Payor"), promises to pay to the order of Computer Associates International, Inc., a Delaware corporation, or its registered assigns (the "Payee"), in lawful money of the United States of America, the Effective Date Principal Amount, together with all accrued and unpaid interest thereon as hereinafter provided.

        The following is a statement of the rights of the Payee and the conditions to which this Note is subject:

        "Effective Date" means the date on which the Payor closes an initial public offering of its common stock.

        "Effective Date Principal Amount" means the aggregate principal amount outstanding under this promissory note, together with any accrued but unpaid interest thereon, as of the Effective Date.

        "Obligations" mean the principal, interest and other amounts payable under this Note.

        "Maturity Date" means the first day of the month immediately following the sixteenth anniversary of the Effective Date.

        "Quarterly Anniversary Dates" means each of the sixty (60) calendar dates occurring quarterly beginning with the date fifteen (15) months after the Effective Date and ending with the date one hundred ninety-two (192) months after the Effective Date.

        "Quarterly Payment Dates" means each of the sixty (60) calendar dates occurring on the first day of the month immediately following each of the Quarterly Anniversary Dates.

        "Quarterly Principal Amount" means the quotient of the Effective Date Principal Amount divided by sixty (60).

"Treasury Bill Rate" means during each one-year period beginning on April 1 and ending on March 31 during the term hereof, the monthly average yield on United States Treasury Securities—Constant Maturity Series issued by the United States Government for a term of ten (10) years, as published by the Federal Reserve Board in Federal Reserve Statistical Release H.15 as "Averages of Business Days" (the "Rate Release") for April of such one-year period and available at http://www.federalreserve.gov/releases/h15/data/m/tcm10y.txt. If the Rate Release is not available at the foregoing location, ACCPAC shall obtain it from an alternate publication or source which is acceptable to Payee.

2.

Payment of Interest and Principal.

(a)

The principal amount of this Note shall be due and payable quarterly in sixty (60) consecutive installments of the Quarterly Principal Amount on each of the Quarterly Payment Dates, provided, however, that the last such payment shall be in the amount necessary to repay in full all unpaid principal amount of this Note on the Maturity Date.

(b)

Interest shall accrue on the unpaid principal balance of this Note from the Effective Date until the Maturity Date at a variable rate equal to the Treasury Bill Rate plus one half of one percent (0.5%).

Each determination of the Treasury Bill Rate by the Payor shall be conclusive and binding absent manifest error. If, with respect to the Treasury Bill Rate, the sale of treasury securities by the United States Government has been suspended, or treasury securities are not being offered for sale by the United States Government, or the weekly average yield is no longer printed by the Federal Reserve Board in Federal Reserve

Statistical Release H.15 or any successor format, then the Payor shall forthwith give notice thereof to the Payee and the Payee shall determine a new index for determining the interest rate to be charged on this Note which, in the good faith judgment of the Payee, shall be substantially equivalent to the Treasury Bill Rate, and the Payee shall forthwith so advise the Payor.

(c)

Interest on the unpaid principal balance of this Note shall be payable quarterly in arrears on each of the Quarterly Payment Dates, provided, however, that the last such payment shall be in the amount necessary to repay in full all unpaid principal amount of this Note on the Maturity Date.



(d)

All payments hereunder shall be made in lawful money of the United States of America by wire transfer of immediately available funds in accordance with the instructions provided by the Payee to the Payor.

        (c)    Involuntary Bankruptcy or Insolvency Proceedings.    Proceedings for the appointment of a receiver, trustee, liquidator or custodian of the Payor or of all or a substantial part of the respective property thereof, or an involuntary case or other proceedings seeking liquidation, reorganization or other relief with respect to the Payor or the debts thereof under any bankruptcy, insolvency or other similar law now or hereafter in effect shall be commenced and an order for relief entered, or such case or proceeding shall not be dismissed or discharged within thirty (30) days of commencement.
