Testing Laboratories, Inc. ("USDTL") reported in Item 2 on the Form 8-K filed on
December 17, 2003,  the  following  unaudited pro forma  condensed  consolidated

         Pro forma Condensed Consolidated Balance Sheet at
            September 30, 2003                                            F-1

         Pro forma Condensed Consolidated Statement of
         Operations for the Year Ended September 30, 2003                 F-2


     The pro forma  condensed  consolidated  balance  sheet of the Company as of
September 30, 2003  reflects the financial  position of the Company after giving
effect to the disposition of the business and net assets, excluding cash, of its
USDTL  subsidiary and assume the  disposition  took place on September 30, 2003.
The pro forma condensed  consolidated statement of operations for the year ended
September 30, 2003 assumes the disposition took place on September 30, 2002, and
is based on the operations of the Company for the year ended September 30, 2003.

     The unaudited pro forma condensed  consolidated  financial  statements have
been prepared by the Company based upon  assumptions  deemed  appropriate by it.
These statements are not necessarily indicative of the future financial position
or results of  operations  or actual  results  that would have  occurred had the
transaction  been in effect as of the dates  presented.  The unaudited pro forma
condensed  consolidated  financial statements should be read in conjunction with
the Company's historical  financial  statements and related notes.  Furthermore,
the historical  amounts as of September 30, 2003 and for the year then ended are
unaudited and therefore are subject to further  adjustment upon  finalization of
the Company's  year-end audit. For the purposes of this pro forma  presentation,
the USDTL  amounts  included in the  historical  amounts are not  presented as a
discontinued operation.
