                                  ACQUISITION NOTE

July 30, 1997
Toronto, Ontario

MATURITY DATE:    July 1, 2007

FOR VALUE RECEIVED, the undersigned (the "Maker") acknowledges itself
indebted to and promises to pay to Heartsoft Inc. (the "Holder") on the dates
specified below at 225 Richmond Street West, Suite 400, Toronto, Ontario, M5V
I W2 (or at such other place as the Holder may from time to time designate in
writing to the Maker), the principal sum of $1,225,000 (one million two
hundred twenty-five thousand dollars)(the "Principal Sum") in lawful money
of Canada, together with interest thereon as set forth herein.

The Principal Sum plus all accrued and unpaid interest thereon shall be due
and payable by the Maker to the Holder in full on July 1, 2007.

The Principal Sum from time to time outstanding shall bear interest from and
after the date hereof at the rate of five percent (5%) per annum, payable in
U.S. dollars, compounded annually both before and after demand, default,
maturity and judgment with interest on overdue principal and interests at the
same rate until the date of payment in full.  The Maker shall pay all accrued
and unpaid interest on the principal amount outstanding from time to time,
annually, in arrears, on or before January 30 of each year.

In the event that the Maker defaults in payment of any sum due hereunder, and
fails to correct that default within 30 days of receiving written notice from
the Holder, the Principal Sum then outstanding together with accrued but
unpaid interest may, at the Holder's option, be accelerated and immediately
become due and payable in full, with interest thereon from such date at the
rate as specified herein.

So long as the Maker is not in default in the making of any payment due
hereunder, it shall have the right to prepay at any time and from time to
time all or any part of the Principal Sum then outstanding, and any interest
thereon, without notice, bonus or penalty, provided that the right of the
Maker to make any such prepayments shall be conditional upon payment by the
Maker to the Holder of all accrued and unpaid interest owing in respect of
the Principal Sum to the date of any such prepayment.

The provisions of this promissory note shall enure to the benefit of the
Holder (who may not transfer, assign, pledge or otherwise encumber this
promissory note without the express written consent of the Maker, which
consent may be unreasonably withheld) and shall be binding upon the Maker and
its successors and assigns.  The Maker hereby waives presentment, protest,
demand, notice of protest and notice of dishonor of this promissory note and
expressly agrees that this promissory note and any payment due hereunder may
be extended from time to time by the Holder without in any way affecting the
liability of the Maker.

<PAGE>

The Maker agrees to pay to the Holder 100% of Gross Receipts, as defined in
the offering memorandum of the Maker dated May 30, 1997 (the "Offering
Memorandum"), on an annual basis, until all of the interest owing under this
promissory note is paid in full, and to pay to the Holder 44% of
Distributable Cash (as defined in the Offering Memorandum) until all
principal owing under this promissory note has been paid in full.

This promissory note is issued by the Maker and accepted by the Holder as
partial payment of the consideration due under a software agreement dated
July 30, 1997 between the Maker and the Holder, and this promissory note is
subject to the terms and conditions of that agreement.

This promissory note shall be governed by and construed in accordance with
the laws of the Province of Ontario and the laws of Canada applicable therein.
