         This SECOND AMENDMENT TO AGREEMENT AND PLAN OF MERGER dated as of

dated as of November 9, 1995, as amended by the First Amendment to the Agreement
and Plan of Merger dated as of February 2, 1996, including the exhibits and
schedules thereto (the "Merger Agreement") by and among Fairchild, RHI, TFC and
Shared Technologies. Terms not otherwise defined herein which are defined in the
Merger Agreement shall have the same respective meanings herein as therein.

         WHEREAS, Fairchild, RHI, TFC and Shared Technologies have agreed to
modify certain terms and conditions of the Merger Agreement as specifically set
forth in this Second Amendment.

         NOW, THEREFORE, in consideration of the premises and mutual agreements
contained herein and for other good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, the parties hereto agree as
follows:

                                    ARTICLE I

                         AMENDMENTS TO MERGER AGREEMENT

         1.1 The following shall be added as a new final paragraph to Schedule
3.1(b) to the Merger Agreement, "Summary of Terms of Special Preferred Stock":

         "The terms of the Special Preferred Stock will provide, or Fairchild,
         RHI and Shared Technologies shall enter into an agreement giving,
         Shared Technologies the option to extend the final maturity of the
         Special Preferred Stock from March 31, 2007, to March 31, 2008. If such
         option is exercised, Shared Technologies will pay a dividend to the
         holders of the Special Preferred Stock at the same rate payable on the
         Senior Discount Notes due 2006 to be issued by a subsidiary of the
         Surviving Corporation in connection with the Merger, calculated on the
         outstanding liquidation preference of the Special Preferred Stock. Such
         dividend shall accrue from March 31, 2007, and be payable quarterly
         beginning June 30, 2007."

         1.2 Section 6.7(a) of the Merger Agreement is amended by adding "(the
'Closing Date Balance Sheet')," after the words "Effective Date" on the last





line of such section, such that such line reads as follows:

         "......gies on the Effective Date (the "Closing Date Balance Sheet"),
         is at least $80,000,000);........ ."

         1.3 Section 6.7(b) of the Merger Agreement is amended in its entirety
to read as follows:

         "(b)   except as contemplated by Schedule 9.1 and except for the
                assignment to RHI by Fairchild of Fairchild's receivables (the
                "Permitted Receivables Assignment"), in an amount of $9,000,000,
                there has not been any direct or indirect redemption, purchase
                or other acquisition of any shares of capital stock of Fairchild
                or any of its subsidiaries, or any declaration, setting aside or
                payment of any dividend or other distribution by Fairchild or
                any of its subsidiaries in respect of their capital stock;
                provided that the Permitted Receivables Assignment shall not
                reduce the net worth of Fairchild to less than $80,000,000.
                Notwithstanding the foregoing, if the Effective Time shall not
                have occurred on or prior to March 15, 1996, the amount of the
                Permitted Receivables Assignment shall be increased to the
                maximum amount which would not cause the net worth of Fairchild,
                as evidenced by the Closing Date Balance Sheet, to be less than
                $80,000,000. Within 90 days of the Closing Date, Arthur
                Andersen, L.L.P. will prepare and deliver to the parties an
                audited balance sheet of Fairchild as of the Closing Date (the
                "Audited Balance Sheet"). In the event that the net worth of
                Fairchild, as shown on the Audited Balance Sheet, (x) is less
                than $80,000,000, Fairchild shall pay to Shared Technologies an
                amount in cash equal to such difference or (y) is more than
                $80,000,000, Shared Technologies shall pay to Fairchild an
                amount in cash equal to such difference; provided that no such
                cash payment, when taken together with the amount of receivables
                assigned to RHI by Fairchild pursuant to this paragraph, shall
                be required in an amount greater than the amount of the
                Permitted Receivables Assignment."

         1.4 The following shall be added as a new Section 8.12 of the Merger
Agreement:

         "8.12 Post-Merger Sale of Shared Technologies Cellular, Inc. RHI agrees
         that if, within 150 days of the Effective Time, the Surviving
         Corporation shall receive cash proceeds from the sale of its interest,
         as of this date, in STCI, then RHI shall contribute to the Surviving
         Corporation, a sum equal to 40% of such cash proceeds received by the
         Surviving Corporation, up to a maximum contribution of $1,600,000."






         1.5 Section 10.1(c) of the Merger Agreement is hereby amended by
deleting the date "March 8, 1996," and inserting the date "March 15, 1996," in
lieu thereof.

         1.6 Section 10.1(d) shall be amended by deleting the words "..., at the
Special Meeting of (including any adjournment thereof)," and adding at the end
of such section the words "on or before March 4, 1996". ARTICLE II

                     AMENDMENTS TO THE TAX SHARING AGREEMENT
                                   (EXHIBIT E)

         2.1 The parties hereto agree to amend The Tax Sharing Agreement as set
forth as Exhibit E to the Merger Agreement to provide for the following
language:

         (i) Notwithstanding any other representation in the Merger Agreement or
in the Tax Sharing Agreement, TFC and RHI make no representation or warranty as
to (i) the amount of any net operating loss and tax credits of the TFC Group
allocable to FII or VSI at the Effective Date as a result of the operations of
FII and VSI prior to the Effective Date; and (ii) the amount of any reduction in
tax payable by Shared Technologies due to utilization of any net operating loss
or tax credit of the TFC Group allocable to FII and VSI as a result of the
operations of FII and VSI prior to the Effective Date.

         (ii) Notwithstanding any other provision of the Tax Sharing Agreement,
Shared Technologies shall not share with TFC and RHI any reduction in the tax
payment of Shared Technologies as a result of Shared Technologies utilizing any
net operating losses or tax credits of the TFC Group allocable to FII or VSI at
the Effective Date or as a result of operations of FII and VSI prior to the
Effective Date.

                                   ARTICLE III

                        PROVISIONS OF GENERAL APPLICATION

Amendment shall be controlling.
