ITEM 2.    ACQUISITION OR DISPOSITION OF ASSETS

        On June 30, 1998, INTERLINQ Software Corporation (the "Company")
acquired all of the right, title and interest in and to substantially all of
the assets and business of Logical Software Solutions Corporation, a Maryland
corporation ("LSSC"), an enterprise application integration developer and
service provider, pursuant to an Asset Purchase Agreement by and among the
Company, LSSC and certain shareholders of LSSC (the "Purchase Agreement").
Through this transaction, the Company is acquiring LSSC's technology,
intellectual property and customer base, and key LSSC personnel will join the
Company. The Company intends to continue using the acquired assets as they were
used by LSSC. The Company intends to integrate the technology with its existing
products and to offer significant enhancements to the product formerly owned by
LSSC through release of an upgraded version. The assets were purchased for
$3,600,001 in cash and 233,334 unregistered shares of common stock of the
Company, valued at $1,400,000.

        The consideration for the acquisition was determined in arm's-length
negotiations between the Company and LSSC. The Company financed the cash
purchase price through cash on hand.

        The Company will account for the acquisition as a purchase. The Company
expects to record a nonrecurring charge of $3 million to $4 million in the
quarter ending June 30, 1998, for in-process research and development.

        The Purchase Agreement and the press release issued in connection with
the closing of this acquisition are filed as exhibits to this report and are
incorporated herein by reference.
