ITEM 2.  ACQUISITION OR DISPOSITION OF ASSETS

On July 25, 2003 (the "Closing") Billserv, Inc., a Nevada corporation (the
"Company") sold substantially all of its assets (the "Business") to Saro, Inc.,
a Delaware corporation (the "Purchaser"), which is a wholly owned subsidiary of
CyberStarts, Inc., a Delaware corporation (the "Sale").

The aggregate selling price for the Business was $4,800,000 (the "Purchase
Price") plus the Purchaser's assumption of certain liabilities of the Company.
The Purchase Price was determined through extensive negotiations between the
Purchaser and the Company. The board of directors of the Company, in its
reasonable business judgment, approved the Purchase Price based upon the
following factors: 1) the extensive search for a purchaser of the Business; 2)
the number of offers made by potential purchasers for the Business; 3) the
Company's ability to raise other sources of capital to operate the Business; and
4) the future trends in the industry of the Business.

At Closing, the Purchaser paid the Company $4,100,000 in cash. The Company may
earn an additional $700,000 based upon two earnouts calculated upon gross
revenues of the Business for the four consecutive quarters following the
Closing, the first quarter of which begins the first day of the first full month
after the Closing.

The pro forma financial information required by this item will be filed by
amendment not later than 60 days after the date of the filing of this report.
