EXHIBIT 10.7

                                                                  CONFORMED COPY

                                    PARENT GUARANTEE AGREEMENT dated as of March
                           12,  1996,   between  SHARED   TECHNOLOGIES  INC.,  a
                           Delaware  corporation  (the  "Guarantor",  which term
                           shall,  after the  Merger  referred  to in the Credit
                           Agreement  referred to below,  include the  surviving
                           corporation in such Merger) and CREDIT SUISSE, a bank
                           organized  under  the  laws  of  Switzerland,  acting
                           through its New York branch, as collateral agent (the
                           "Collateral  Agent")  for  the  Secured  Parties  (as
                           defined in the Credit Agreement referred to below).


                  Reference  is made to the Credit  Agreement  dated as of March
12, 1996 (as amended,  supplemented or otherwise modified from time to time, the
"Credit Agreement"), among Shared Technologies Fairchild Communications Corp., a
Delaware corporation (the "Borrower"),  the Guarantor,  the lenders from time to
time party thereto (the "Lenders"),  Credit Suisse, as administrative  agent (in
such  capacity,  the  "Administrative  Agent") and as collateral  agent (in such
capacity,  the "Collateral Agent") for the Lenders, the fronting banks listed on
Schedule 2.20  (the  "Fronting  Banks"),  and each of  Citicorp  USA,  Inc.  and
NationsBank, N.A., as documentation agent (individually and collectively in such
capacity,  the  "Documentation  Agent").  Capitalized  terms used herein and not
defined  herein  shall have the  meanings  assigned  to such terms in the Credit
Agreement.

                  The Lenders have agreed to make Loans to the Borrower, and the
Fronting  Banks have  agreed to issue  Letters of Credit for the  account of the
Borrower,  pursuant  to,  and upon  the  terms  and  subject  to the  conditions
specified  in,  the  Credit  Agreement.  As the owner of all of the  issued  and
outstanding  capital stock of the Borrower,  the Guarantor  acknowledges that it
will derive substantial  benefit from the making of the Loans by the Lenders and
the issuance of the Letters of Credit by the Fronting Banks.  The obligations of
the Lenders to make Loans and of the Fronting  Banks to issue  Letters of Credit
are  conditioned  on,  among other  things,  the  execution  and delivery by the
Guarantor of a Guarantee Agreement in the form hereof. As consideration therefor
and in order to induce the Lenders to make Loans and the Fronting Banks to issue
Letters of Credit, the Guarantor is willing to execute this Agreement.

                  Accordingly, the parties hereto agree as follows:

                  SECTION   1.   Guarantee.   The   Guarantor    unconditionally
guarantees,  as a primary  obligor  and not merely as a surety,  (a) the due and
punctual  payment of (i) the  principal  of and  premium,  if any,  and interest
(including interest accruing during the pendency of any bankruptcy,  insolvency,
receivership  or other  similar  proceeding,  regardless  of whether  allowed or
allowable  in  such  proceeding)  on the  Loans,  when  and as due,  whether  at
maturity,  by  acceleration,  upon  one or  more  dates  set for  prepayment  or
otherwise,  (ii) each  payment  required  to be made by the  Borrower  under the
Credit Agreement in respect of any Letter of Credit,  when and as due, including
payments in respect of  reimbursement  of  disbursements,  interest  thereon and
obligations to provide cash collateral and (iii) all other monetary obligations,
including fees,  costs,  expenses and indemnities,  whether primary,  secondary,
direct, contingent,  fixed or otherwise (including monetary obligations incurred
during the pendency of any bankruptcy, insolvency, receivership or other similar
proceeding,  regardless of whether allowed or allowable in such proceeding),  of
the Loan Parties to the Secured Parties under the Credit Agreement and the other
Loan  Documents,  (b)  the  due  and  punctual  performance  of  all  covenants,
agreements, obligations and liabilities of the Loan Parties under or pursuant to
the Credit  Agreement  and the other  Loan  Documents  and (c) unless  otherwise
agreed upon in writing by the





applicable  Lender party thereto,  all obligations of the Borrower,  monetary or
otherwise,  under each Interest Rate  Protection  Agreement  entered into with a
counterparty  that  was a Lender  at the  time  such  Interest  Rate  Protection
Agreement was entered into (all the monetary and other  obligations  referred to
in  the  preceding   clauses (a)  through  (c)  being  collectively  called  the
"Obligations").  The  Guarantor  further  agrees  that  the  Obligations  may be
extended or renewed,  in whole or in part,  without  notice to or further assent
from it, and that it will remain bound upon its  guarantee  notwithstanding  any
extension  or renewal of any  Obligation.  The  Guarantor  further  agrees  that
(a) the  maturity of the  Obligations  guaranteed  hereby may be  accelerated as
provided  in  Article VII  of the  Credit  Agreement  for  the  purposes  of the
Guarantor's  guarantee  herein,  notwithstanding  any stay,  injunction or other
prohibition   preventing  such   acceleration  in  respect  of  the  Obligations
guaranteed  hereby,  and (b) in the event of any  declaration of acceleration of
such obligations as provided in such Article VII,  such Obligations  (whether or
not due and payable) shall forthwith become due and payable by the Guarantor for
the purposes of this Section.

                  SECTION 2.  Obligations  Not  Waived.  To the  fullest  extent
permitted by applicable  law, the  Guarantor  waives  presentment  to, demand of
payment  from and protest to the  Borrower of any of the  Obligations,  and also
waives  notice  of  acceptance  of its  guarantee  and  notice  of  protest  for
nonpayment.  To the fullest extent  permitted by applicable law, the obligations
of the  Guarantor  hereunder  shall not be  affected  by (a) the  failure of the
Collateral  Agent or any other Secured Party to assert any claim or demand or to
enforce  or  exercise  any right or remedy  against  the  Borrower  or any other
guarantor of the Obligations under the provisions of the Credit  Agreement,  any
other Loan  Document or  otherwise,  (b) any  rescission,  waiver,  amendment or
modification  of, or any  release  from any of the terms or  provisions  of this
Agreement,  any other  Loan  Document,  any  Guarantee  or any other  agreement,
including  with  respect to any other  guarantor of the  Obligations  or (c) the
failure to perfect  any  security  interest  in, or the  release  of, any of the
security  held by or on behalf  of the  Collateral  Agent or any  other  Secured
Party.

                  SECTION 3. Security.  The Guarantor  authorizes the Collateral
Agent and each of the other  Secured  Parties to (a) take and hold  security for
the payment of this Guarantee and the Obligations and exchange,  enforce,  waive
and release any such  security,  (b) apply such security and direct the order or
manner of sale  thereof  as they in their  sole  discretion  may  determine  and
(c) release or substitute any one or more endorsees,  other  guarantors or other
obligors.

                  SECTION 4. Guarantee of Payment.  The Guarantor further agrees
that its  guarantee  constitutes  a  guarantee  of  payment  when due and not of
collection,  and  waives  any  right to  require  that any  resort be had by the
Collateral  Agent or any other  Secured  Party to any of the  security  held for
payment of the Obligations or to any balance of any deposit account or credit on
the books of the  Collateral  Agent or any other  Secured  Party in favor of the
Borrower or any other person.

                  SECTION 5. No  Discharge or  Diminishment  of  Guarantee.  The
obligations  of the Guarantor  hereunder  shall not be subject to any reduction,
limitation,   impairment  or   termination   for  any  reason  (other  than  the
indefeasible payment in full in cash of the Obligations), including any claim of
waiver, release, surrender,  alteration or compromise of any of the Obligations,
and shall not be subject to any defense or setoff,  counterclaim,  recoupment or
termination   whatsoever   by   reason   of  the   invalidity,   illegality   or
unenforceability   of  the  Obligations  or  otherwise.   Without  limiting  the
generality of the foregoing,  the  obligations of the Guarantor  hereunder shall
not be  discharged  or  impaired  or  otherwise  affected  by the failure of the
Collateral  Agent or any other Secured Party to assert any claim or demand or to
enforce any remedy under the Credit  Agreement,  any other Loan  Document or any


                                       2


other agreement,  by any waiver or modification of any provision of any thereof,
by any default, failure or delay, wilful or otherwise, in the performance of the
Obligations,  or by any other act or omission that may or might in any manner or
to any extent vary the risk of the Guarantor or that would otherwise  operate as
a  discharge  of the  Guarantor  as a matter  of law or equity  (other  than the
indefeasible payment in full in cash of all the Obligations).

                  SECTION 6. Defenses of Borrower Waived.  To the fullest extent
permitted  by  applicable  law,  the  Guarantor  waives any defense  based on or
arising  out of any  defense  of the  Borrower  or the  unenforceability  of the
Obligations or any part thereof from any cause,  or the cessation from any cause
of the liability of the Borrower,  other than the final and indefeasible payment
in full in cash of the  Obligations.  The Collateral Agent and the other Secured
Parties may, at their election, foreclose on any security held by one or more of
them by one or more judicial or nonjudicial  sales,  accept an assignment of any
such  security  in lieu of  foreclosure,  compromise  or adjust  any part of the
Obligations,  make any  other  accommodation  with  the  Borrower  or any  other
guarantor  or exercise  any other right or remedy  available to them against the
Borrower or any other guarantor,  without  affecting or impairing in any way the
liability of the Guarantor  hereunder  except to the extent the Obligations have
been  fully,  finally  and  indefeasibly  paid in cash.  To the  fullest  extent
permitted by applicable law, the Guarantor waives any defense arising out of any
such election even though such election operates, pursuant to applicable law, to
impair or to extinguish any right of reimbursement or subrogation or other right
or remedy of the Guarantor  against the Borrower or any other guarantor,  as the
case may be, or any security.

                  SECTION 7. Agreement to Pay; Subordination.  In furtherance of
the foregoing and not in limitation of any other right that the Collateral Agent
or any other  Secured  Party has at law or in equity  against the  Guarantor  by
virtue  hereof,  upon the failure of the Borrower or any other Loan Party to pay
any Obligation  when and as the same shall become due,  whether at maturity,  by
acceleration,  after notice of  prepayment or  otherwise,  the Guarantor  hereby
promises to and will forthwith pay, or cause to be paid, to the Collateral Agent
or such other  Secured  Party as  designated  thereby in cash the amount of such
unpaid Obligations.  Upon payment by the Guarantor of any sums to the Collateral
Agent or any  Secured  Party as  provided  above,  all  rights of the  Guarantor
against the Borrower arising as a result thereof by way of right of subrogation,
contribution,  reimbursement,  indemnity or  otherwise  shall in all respects be
subordinate and junior in right of payment to the prior indefeasible  payment in
full in cash  of all the  Obligations.  In  addition,  any  indebtedness  of the
Borrower now or hereafter held by the Guarantor is hereby  subordinated in right
of payment to the prior payment in full of the Obligations.  If any amount shall
erroneously  be  paid to the  Guarantor  on  account  of  (i) such  subrogation,
contribution,  reimbursement,  indemnity  or  similar  right  or  (ii) any  such
indebtedness of the Borrower, such amount shall be held in trust for the benefit
of the Secured Parties and shall forthwith be paid to the Collateral Agent to be
credited against the payment of the  Obligations,  whether matured or unmatured,
in accordance with the terms of the Loan Documents.

                  SECTION   8.   Information.    The   Guarantor   assumes   all
responsibility for being and keeping itself informed of the Borrower's financial
condition and assets,  and of all other  circumstances  bearing upon the risk of
nonpayment of the Obligations and the nature, scope and extent of the risks that
the  Guarantor  assumes  and  incurs  hereunder,  and  agrees  that  none of the
Collateral  Agent or the other Secured  Parties will have any duty to advise the
Guarantor of information known to it or any of them regarding such circumstances
or risks.

                  SECTION 9. Termination. The Guarantee made hereunder (a) shall
terminate when


                                       3



all the Obligations have been  indefeasibly paid in full and the Lenders have no
further commitment to lend under the Credit Agreement, the L/C Exposure has been
reduced  to zero and the  Fronting  Banks have no  further  obligation  to issue
Letters  of Credit  under the  Credit  Agreement  and (b) shall  continue  to be
effective or be reinstated,  as the case may be, if at any time payment,  or any
part thereof,  of any  Obligation is rescinded or must  otherwise be restored by
any Secured Party or the Guarantor upon the bankruptcy or  reorganization of the
Borrower, the Guarantor or otherwise.

                  SECTION 10. Binding Agreement;  Assignments.  Whenever in this
Agreement  any of the parties  hereto is referred  to, such  reference  shall be
deemed to include the successors  and assigns of such party;  and all covenants,
promises and  agreements by or on behalf of the Guarantor  that are contained in
this  Agreement  shall bind and inure to the  benefit  of each party  hereto and
their respective  successors and assigns.  This Agreement shall become effective
when a counterpart  hereof  executed on behalf of the Guarantor  shall have been
delivered  to the  Collateral  Agent and a  counterpart  hereof  shall have been
executed on behalf of the Collateral Agent, and thereafter shall be binding upon
the Guarantor  and the  Collateral  Agent and their  respective  successors  and
assigns,  and shall inure to the benefit of the Guarantor,  the Collateral Agent
and the other Secured  Parties,  and their  respective  successors  and assigns,
except  that the  Guarantor  shall not have the right to  assign  its  rights or
obligations  hereunder or any interest herein (and any such attempted assignment
shall be void).

                  SECTION 11. Waivers; Amendment. (a) No failure or delay of the
Collateral  Agent in exercising any power or right  hereunder shall operate as a
waiver  thereof,  nor shall any single or partial  exercise of any such right or
power, or any abandonment or  discontinuance of steps to enforce such a right or
power,  preclude  any other or further  exercise  thereof or the exercise of any
other right or power.  The rights and remedies of the Collateral Agent hereunder
and of the other Secured  Parties under the other Loan  Documents are cumulative
and are not exclusive of any rights or remedies that they would  otherwise have.
No waiver of any provision of this  Agreement or consent to any departure by the
Guarantor  therefrom  shall in any event be  effective  unless the same shall be
permitted  by  paragraph (b)  below,  and then such  waiver or consent  shall be
effective only in the specific  instance and for the purpose for which given. No
notice or demand on the Guarantor in any case shall entitle the Guarantor to any
other or further notice or demand in similar or other circumstances.

         (b) Neither  this  Agreement  nor any  provision  hereof may be waived,
amended or modified except pursuant to a written  agreement entered into between
the Guarantor and the Collateral  Agent,  with the prior written  consent of the
Required Lenders (except as otherwise provided in the Credit Agreement).

                  SECTION 12.  GOVERNING LAW. THIS  AGREEMENT  SHALL BE GOVERNED
BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK.

                  SECTION 13. Notices. All communications and notices hereunder
shall be in  writing  and  given  as  provided  in  Section  9.01 of the  Credit
Agreement.  All  communications  and notices hereunder to the Guarantor shall be
given to it at 100 Great Meadow Road Wethersfield,  CT 06109, Attention of Chief
Executive Officer.

                  SECTION 14.  Survival of Agreement. All covenants, agreements,
representations  and  warranties  made  by  the  Guarantors  herein  and  in the
certificates  or other  instruments  prepared or delivered in connection with or
pursuant to this  Agreement or any other Loan  Document  shall be


                                       4


considered  to have  been  relied  upon by the  Collateral  Agent  and the other
Secured Parties and shall survive the making by the Lenders of the Loans and the
issuance  of the  Letters  of Credit by the  Fronting  Banks  regardless  of any
investigation made by the Secured Parties or on their behalf, and shall continue
in full force and effect as long as the principal of or any accrued  interest on
any Loan or any other fee or amount  payable  under this  Agreement or any other
Loan Document is outstanding  and unpaid or the L/C Exposure does not equal zero
and as long as the Commitments and the L/C Commitment have not been terminated.

                  SECTION 15.  Counterparts.  This  Agreement may be executed in
counterparts,  each of which shall constitute an original, but all of which when
taken together shall constitute a single contract, and shall become effective as
provided in Section 10. Delivery of an executed signature page to this Agreement
by  facsimile  transmission  shall be as  effective  as  delivery  of a manually
executed counterpart of this Agreement.

                  SECTION 16.  Rules    of   Interpretation.    The   rules   of
interpretation  specified  in  Section 1.02  of the  Credit  Agreement  shall be
applicable to this Agreement.



                  IN WITNESS WHEREOF, the parties hereto have duly executed this
Agreement as of the day and year first above written.
