ITEM 2.           ACQUISITION OR DISPOSITION OF ASSETS.
- -------           -------------------------------------

         As reported in Form 8-K dated September 30, 1999 and filed with the
Securities and Exchange Commission on October 15, 1999 by Response USA, Inc.
(the "Company"), the Company sold the stock of two of its wholly owned
subsidiaries, United Security Systems, Inc. and The Jupiter Group, Inc. d/b/a
Triple A Patrol to Vector Security, Inc. (the "Sale Transaction"). This Form
8-K/A provides pro forma financial information required under Item 7 of Form
8-K. Item 7 to the Form 8-K is hereby amended and restated in its entirety as
provided below.


         The pro forma adjustments are based on available information and
upon certain assumptions that management believes are reasonable under the
circumstances. The unaudited pro forma financial statements and accompanying
notes should be read in conjunction with the historical Consolidated
Financial Statements of the Company including the notes thereto, and other
financial information pertaining to the Company. The unaudited pro forma
financial statements do not purport to represent what the actual results of
operations or the actual financial position would have been if the Sale
Transaction and the use of related proceeds had, in fact, occurred on such
assumed dates or to project the Company's results of operations or financial
position for any future period or date. The unaudited pro forma consolidated
financial statements only reflect effects from the Sale Transaction and the
use of related proceeds.


         The Private Securities Litigation Reform Act of 1995 (the "Reform Act")
provides a "safe harbor" for forward-looking statements to encourage companies
to provide prospective information so long as those statements are identified as
forward-looking and are accompanied by meaningful cautionary statements
identifying important factors that would cause actual results to differ
materially from those discussed in the statement. The Company desires to take
advantage of the "safe harbor" provisions of the Reform Act. Except for the
historical information contained herein, the matters discussed in this Form
8-K/A are forward-looking statements, which involve risks and uncertainties.
Although the Company believes that the expectations reflected in such
forward-looking statements are based upon reasonable assumptions, it can give no
assurance that its expectations will be achieved. Important factors that can
cause actual results to differ materially from the Company's expectations are
disclosed in conjunction with the forward-looking statements or elsewhere
herein.

         The following unaudited pro forma consolidated statements of operations
for the year ended June 30, 1999 and the three months ended September 30, 1999
give effect to the Sale Transaction and the use of the proceeds received from
such sale to acquire and


                                      -2-



retire 747,582 shares of treasury stock and to cancel 437,500 shares of Common
Stock originally held in escrow, as if such events had been completed at July 1,
1998. The pro forma information is based on the historical financial statements
of the Company giving effect to the adjustments described in the accompanying
notes to the unaudited pro forma financial information.

         THESE PRO FORMA STATEMENTS OF OPERATIONS MAY NOT BE INDICATIVE OF THE
RESULTS THAT ACTUALLY WOULD HAVE OCCURRED IF THE SALE TRANSACTION HAD OCCURRED
ON JULY 1, 1998.

        EXHIBITS.

        (a) Financial Statements of Business Acquired: N/A.
