         To record the acquisition of IPP and Paramount for a purchase price
         consisting of cash, 555,589 unregistered shares of Common Stock, 13,786
         shares of 14% Preferred, and Nominal Value Warrants to purchase 297,781
         shares of Common Stock; assumption and immediate payoff of most of the
         acquired debt; the write-up of acquired property, plant, and equipment
         to its fair value; the recording of the increased value of IPP's and
         Paramount's existing phone contracts; the value of four Non-compete
         Agreements with three former officers of IPP and one former officer of
         Paramount; and the recording of the fair value of the Nominal Value
         Warrants. The shares of Common Stock were valued at the average of the
         BID and ASK on the date of closing (March 15, 1996) as reported by
         NASDAQ, less an unregistered discount of 35% ("Discounted Market
         Price"). Each share of the 14% Preferred was valued based on its
         conversion into ten shares of Common Stock priced at the Discounted
         Market Price. The Nominal Value Warrants were valued based on their
         equivalent common shares at the Discounted Market Price less the
         nominal exercise price per share. As required by purchase accounting,
         the accumulated retained earnings or deficits of IPP and Paramount
         prior to the date of acquisition were eliminated.

         To record the restructuring of the Company's long-term debt and
         obligations under capital leases and application of the debt proceeds,
         including - repayment of certain obligations of the Company (payment of
         transaction fees, all outstanding debt and obligations under capital
         leases which had a secured interest in the Company's operating assets,
         certain trade accounts payable and customer commissions, shareholders
         loans, and redemption of the 10%, 8%, and 7% Preferred stock). A
         portion of the outstanding debt at December 31, 1995, was paid with
         16,371 shares of Common Stock. The redemption of the 10%, 8%, and 7%
         Preferred resulted in the recording of a dividend in the amount of
         $2,002,386. An extraordinary loss resulting from the debt payoff, of
         $687,445, was recorded to the accumulated deficit.

         Represents the estimated recurring benefits resulting from the
         acquisitions and the incremental depreciation and amortization
         associated with the acquisitions. The savings are primarily the result
         of backroom efficiencies, including the elimination of certain offices
         and executives and economies of scale in billing and other operating
         areas. The increase in property, plant and equipment is assumed to
         depreciate over 60 months while the intangible assets relating to IPP's
         and Paramount's existing phone contracts is being amortized over 60
         months. The value of the Non-compete Agreements is being amortized over
         the life of the agreements which is 60 months.
