Item 5. Other Events.

         On February 6, 2002, pursuant to an Asset Purchase Agreement dated as
of January 29, 2002 (the "Purchase Agreement") by and among Pegasystems Inc., a
Massachusetts corporation (the "Company"), 1Mind Corporation, a Delaware
corporation ("1Mind"), 1Mind.com, LLC, a Delaware limited liability company and
a wholly owned subsidiary of 1Mind ("Target Subsidiary", and together with
1Mind, the "Sellers"), and the equity holders of 1Mind (the "Equity Holders"),
the Company acquired substantially all of the assets and specified liabilities
of the Sellers. In consideration for the acquired assets, at the closing the
Company (i) issued to 1Mind 384,189 unregistered shares of the Company's common
stock and a warrant to purchase 83,092 additional unregistered shares of the
Company's common stock for $70,808.28 and (ii) deposited into escrow 155,760
unregistered shares of the Company's common stock to secure the indemnification
obligations of the Equity Holders under the Purchase Agreement. The Purchase
Agreement provides for the Company to pay up to approximately $6 million of
additional consideration, payable in the form of common stock or cash, at the
Company's option, if the acquired business achieves specified revenue, backlog
and margin targets relating to 2002.
