Fairchild  Corporation,  a Delaware corporation  ("TFC"), RHI Holdings,  Inc., a
Delaware   corporation   ("RHI")  and  Shared   Technologies  Inc.,  a  Delaware
corporation ("Shared Technologies").

          WHEREAS,  TFC currently  owns all of the  outstanding  common stock of
RHI,  RHI  currently  owns all of the  outstanding  common  stock  of  Fairchild
Industries,  Inc.,  a  Delaware  corporation  ("FII"),  and FII  owns all of the

          WHEREAS,  the  operations  of TFC,  RHI,  FII  and  VSI are  presently
included in the  consolidated  Federal income tax return filed for an affiliated
group  (within the meaning of ss. 1504 of the Internal  Revenue Code of 1986, as
amended ("Code")) (the "TFC Group") of which TFC is the common parent;

          WHEREAS,  TFC,  RHI,  FII  and  Shared  Technologies  have  signed  an
Agreement and Plan of Merger on November 9, 1995, a First Amendment to Agreement
and Plan of Merger as of February 2, 1996, a Second  Amendment to Agreement  and
Plan of Merger as of February 23, 1996 and a Third  Amendment  to Agreement  and
Plan of Merger as of March 1, 1996 (as so amended, the "Merger Agreement") under
which, inter alia, FII will merge into Shared Technologies;
  
          WHEREAS,  TFC,  RHI and  Shared  Technologies  desire to enter into an
agreement  providing for payments  among TFC, RHI and Shared  Technologies  with
respect to certain tax benefits and for indemnification  with respect to certain
tax liabilities;

          NOW,  THEREFORE,  in  consideration  of the premises and of the mutual
covenants and agreements herein contained,  the parties hereto,  intending to be
legally bound, agree as follows:
      
   1. Indemnity
         
         A. Definition

          This agreement applies to all Federal, State, local, and foreign taxes
(including income, franchise,  withholding,  and alternative minimum taxes), and
also includes all interest, penalties and additions imposed with respect to such
amounts (all such taxes and other amounts are collectively, "Taxes").
    
         B. Tax Indemnification
                 
          (1) TFC and RHI,  jointly and  severally,  shall pay and indemnify and
shall hold  Shared  Technologies  harmless  from and  against  (i) all Taxes and
claims for Taxes paid or payable by FII or VSI with  respect to any taxable year
or period of FII or VSI or predecessor  entities of either of them which ends on
or  before  the  date  of  the  merger  of FII  into  Shared  Technologies  (the
"Deconsolidation  Date"),  including any tax liability  which arises because FII
and VSI cease on the  Deconsolidation  Date to be members of the TFC Group or of
any other group filing a combined or consolidated tax return for foreign, state,
or local tax purposes and  including  any tax liability of FII and VSI resulting
from the Fairchild  Reorganization as further described on Schedule 9.1 attached
to the Merger Agreement, and (ii) all taxes and claims for Taxes paid or payable
by FII or VSI by virtue of Section 1.1502-6 of the Treasury  Regulations,  or by
virtue of any similar  provision of foreign,  state, or local law by reason that
FII and VSI were  members  of a group  which  files or has filed a  consolidated
federal income tax return,  or a combined or  consolidated  foreign,  state,  or
local tax return.  For purposes of this  Agreement,  any taxable year  beginning
before and ending after the  Deconsolidation  Date shall be treated as ending on
the Deconsolidation Date.
 
          For purposes of this  Agreement  any income or deduction  arising from
transactions  characterized  as deferred  intercompany  transactions for Federal
income tax purposes  which  occurred  before the  Deconsolidation  Date shall be
deemed  attributable  to a period ending on or before the  Deconsolidation  Date
(the "Pre-Deconsolidation Period").
      
          (2) Shared Technologies shall pay RHI and indemnify RHI and shall hold
RHI  harmless  to  the  extent  of  any  reduction  in  tax  payable  by  Shared
Technologies for any taxable year beginning on or after the Deconsolidation Date
(a  "Post-Deconsolidation  Period") as a result of a final  disallowance  of any
loss, deduction,  or credit claimed by FII or VSI as members of the TFC Group in
a Pre-Deconsolidation  Period and the allowance of such deduction or credit in a
Post-Deconsolidation  Period  (or as a  result  of a  final  determination  that
additional income is to be recognized in a Pre-Deconsolidation Period in lieu of
income which had been recognized in a Post-Deconsolidation Period). Such payment
shall be  limited  in all cases to the  amount of the  reduction  in actual  tax
otherwise payable by Shared Technologies and shall be paid when the reduction in
tax is recognized by Shared Technologies.

          (3)  Notwithstanding  any other  representation  and warranty or other
provision  in the Merger  Agreement  or this  Agreement,  any  reduction  in tax
payable by Shared Technologies for a Post-Deconsolidation  Period as a result of
utilization of net operating loss  carryforwards or tax credit  carryforwards of
FII and VSI originating in a Pre-Deconsolidation  Period shall not result in any
payment  by Shared  Technologies  to RHI of any of the  reduction  in actual tax
otherwise payable by Shared Technologies. All carryforwards and carrybacks shall
be  utilized  in  the  order  provided  by the  Code  and  Treasury  Regulations
thereunder.  Notwithstanding  any other  representation  and  warranty  or other
provision  in the  Merger  Agreement  or this  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 on the  Effective  Date of
the Merger of FII into Shared  Technologies as a result of the operations of FII
and VSI prior to the Effective  Date;  (ii) the amount of any net operating loss
and tax credit of FII and VSI that will be utilized by other  members of the TFC
Group before the Deconsolidation  Date; and (iii) the amount of any reduction in
tax payable by Shared  Technologies due to utilization of any net operating loss
and 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.
 
          (4) Any  reduction  in tax payable by the TFC Group as a result of the
allowance of any additional loss, deduction,  or credit claimed by the TFC Group
on a claim for refund or amended return filed after the Deconsolidation Date for
a  Pre-Deconsolidation   Period  shall  result  in  payment  by  RHI  to  Shared
Technologies of an amount equal to the increase in actual tax otherwise  payable
by Shared Technologies caused by the allowance of the loss,  deduction or credit
claimed by the TFC Group. Said payment shall be made at the time the increase in
tax is paid by Shared Technologies.
 
          (5) Any  reduction  in tax  payable  by the TFC  Group as a result  of
utilization of net operating losses or tax credits of FII or VSI that originated
in a Post-Deconsolidation Period shall result in payment by RHI and TFC, jointly
and  severally,  to Shared  Technologies  of an amount  equal to the increase in
actual tax otherwise  payable by Shared  Technologies  caused by the TFC Group's
use of such net operating  loss or credit.  RHI and TFC,  jointly and severally,
shall pay such amount at the time such increase is calculable.  The TFC Group is
not required to take any action to reduce its taxes to the extent such reduction
causes a permanent tax detriment to the TFC Group.

          (6) Except as provided in Paragraph 1(B)(5),  all tax refunds received
by FII or VSI for any  periods  prior to the  Deconsolidation  Date  received by
Shared Technologies shall be promptly paid by Shared Technologies to RHI.

          (7)  Shared   Technologies  is  responsible   for,  and  will  not  be
indemnified  for, any taxes arising out of an election under ss. 338 of the Code
and Shared  Technologies  will not make any  election  under ss. 338 of the Code
regarding  the  transactions  contemplated  by  the  Merger  Agreement.   Shared
Technologies and RHI agree to report the merger of FII into Shared  Technologies
on their  Federal and state  income tax returns as a statutory  merger under ss.
368(a)(1)(A)  of the Code.  Shared  Technologies  and RHI  agree to  report  all
dividends  declared  and paid by  Shared  Technologies  to RHI with  respect  to
Convertible  Preferred  Stock and Special  Preferred  Stock on their Federal and
State Income Tax Returns as dividends.
 
          (8)  If  any  item  resulting  in  an  indemnification   hereunder  is
disallowed by a taxing authority and all remedies discussed in paragraph 2 below
are  exhausted,   then  the  indemnitee   shall  promptly   return  the  related
indemnification amounts to the indemnitor.

         C. Time for Indemnification
 
          Unless otherwise  specified herein,  payments required under paragraph
1(B) above shall be made not later than the date or dates on which the estimated
payments or returns are filed,  or, if later, the date of any required notice or
exhaustion of remedies, as applicable.

         D. Returns, Payments and Refunds

          (1) The TFC Group shall include the results of FII and VSI  operations
for the  Pre-Deconsolidation  Period,  including  the  results of the  Fairchild
Reorganization  as  described in Schedule  9.1 to the Merger  Agreement,  in its
consolidated  Federal  income tax return  and any  combined  state tax return or
report for the  Pre-Deconsolidation  Period. The TFC Group and RHI shall file or
cause to be filed, when due, all required federal,  state,  foreign,  local, and
other returns,  reports and declarations involving taxes for (either mandatorily
or at the discretion of TFC and on a consolidated,  separate or any other basis)
the operations and assets, including the results of the Fairchild Reorganization
as  described in Schedule  9.1 to the Merger  Agreement,  of FII and VSI for all
taxable periods ending or deemed to end on or before the  Deconsolidation  Date.
Shared  Technologies  shall file or cause to be filed,  when due, all  required,
Federal,  state,  foreign,  local,  and other returns,  reports and declarations
involving  taxes for the  operations  and assets of FII and VSI for any  taxable
period  beginning  on  or  after  the  Deconsolidation   Date.  RHI  and  Shared
Technologies shall cooperate in filing the returns, reports and declarations for
FII and VSI described in this  subparagraph  (1) and shall make relevant records
available to each other and to FII and VSI at no cost.  Each  return,  report or
declaration filed for a Pre-Deconsolidation Period pursuant to this subparagraph
(1) shall be prepared in a manner consistent with the accounting  principles and
methods, elections and practices employed by the TFC Group in preparing the same
or similar  returns,  reports and  declarations for taxable periods prior to the
Deconsolidation Date.

          (2) The TFC Group, RHI and Shared Technologies shall each pay or cause
to be paid to the  appropriate  authorities  all amounts payable with respect to
any  returns,  reports or  declarations  which such party is required to file or
cause to be filed pursuant to the preceding subparagraph (1).

         2. Tax Contests
               
          A. If a  written  claim  is  made by any  taxing  authority  that,  if
successful, could result in the indemnification of Shared Technologies by TFC or
RHI hereunder (an  "Indemnifiable  Claim"),  Shared  Technologies shall promptly
notify  TFC and RHI in writing  of such  fact.  In the event  that such  written
notice is not given  within  thirty (30) days of the receipt of such claim,  the
obligation  to indemnify  with respect to such claim shall  terminate if each of
TFC and RHI is thereafter unable, directly or indirectly, to contest such claim,
pursue  other  administrative  remedies,  or sue for refund upon  payment of the
amount which is the subject of the claim.

          B.  Shared  Technologies  shall  take,  and shall cause FII and VSI to
take,  any and all actions in  connection  with any audit or similar  proceeding
relating to a  Pre-Deconsolidation  Period, or in connection with contesting any
Indemnifiable  Claim,  as RHI shall  reasonably  request from time to time.  RHI
shall   control   all   audits   or   similar   proceedings    relating   to   a
Pre-Deconsolidation Period and all proceedings in connection with contesting any
Indemnifiable Claim and shall be entitled to utilize counsel of its own choosing
in connection  therewith;  provided that,  where the results of any such contest
would have a material adverse impact on the ability of Shared Technologies,  FII
or VSI to obtain  the  benefit  of any item of  deduction,  loss or  credit  (or
require Shared  Technologies,  FII or VSI to recognize additional income) in any
Post-Deconsolidation   Period,   RHI  shall   reasonably   consult  with  Shared
Technologies  in  connection  with such  contest.  In  connection  with any such
proceedings,   RHI,  in  its  sole   discretion,   may:  pursue  or  forego  any
administrative appeal,  proceedings,  hearings and conferences with the relevant
taxing authority;  pay the tax claims and sue for a refund (where applicable law
permits such refund suits) or contest the claim in any other legally permissible
manner;  prosecute  such  contest  to a  determination  in a  court  of  initial
jurisdiction and in any applicable appellate courts; or take any other action it
deems  appropriate.  RHI shall reimburse Shared  Technologies for all reasonable
out-of-pocket  costs  (including fees and  disbursements  of outside counsel and
accountants) incurred in complying with any request by RHI pursuant to the first
sentence of this  subparagraph  (B). If costs are incurred in connection  with a
dispute  involving  both  Pre-Deconsolidation  Period  and  Post-Deconsolidation
Periods,  RHI and Shared Technologies shall agree on a reasonable  allocation of
such costs.

          C. Shared  Technologies  shall not settle or otherwise  compromise any
Indemnifiable  Claim  of FII  and  VSI  without  RHI's  prior  written  consent;
provided,   however,   that,  nothing  contained  herein  shall  require  Shared
Technologies  to contest a claim which it would otherwise be required to contest
pursuant hereto if Shared  Technologies  shall reasonably  consult with RHI with
respect to such claim and shall  waive  payment by RHI of any amount  that might
otherwise be payable by RHI  hereunder by way of indemnity in respect of such or
any similar claim.

          D. The payments for Taxes among TFC, RHI and Shared Technologies under
their  agreement  are not subject to the $4 Million  Basket in Sections 11.2 and
11.3 of the Merger Agreement.

         3. Interest

          If any  amount  payable  by TFC or RHI to  Shared  Technologies  or by
Shared  Technologies to TFC or RHI pursuant to this Agreement is not paid at the
time set forth  herein,  the amount shall bear  interest,  from the date of such
event,  at a rate equal to the rate of interest as described  in ss.  6621(a) of
the Code and computed thereunder from time to time.

         4. Entire Agreement: Prior Tax Agreements

          This Tax  Agreement  constitutes  the entire  agreement of the parties
concerning the subject matter hereof and supersedes and terminates all prior tax
agreements  among TFC, RHI, FII, VSI and the parties hereto effective on the day
immediately preceding the merger of FII into Shared Technologies.

         5. Expenses

          Unless  otherwise  expressly  provided in this  Agreement,  each party
shall bear any and all expenses that arise from its respective obligations under
this Agreement.

         6. Amendment

          This  Agreement  may not be amended  except by an agreement in writing
signed by the parties hereto.
