                         TECHNOLOGY SERVICE GROUP, INC.
                 ANNOUNCES AGREEMENT TO MERGE WITH ELCOTEL, INC.

Roswell,  Georgia,  August 14, 1997 -- Technology  Service Group,  Inc. (Nasdaq:
"TSGI")  announced today that the Company has entered into an Agreement and Plan
of Merger with Elcotel,  Inc.  (Nasdaq:  "ECTL") under which the companies  will
form a strategic combination of their businesses.

Technology  Service  Group,  Inc.  (the  "Company" or "TSG"),  based in Roswell,
Georgia,  is a  leading  provider  of smart  payphone  systems  to the  domestic
Regional  Bell market with sales  revenues of $33.5  million for the fiscal year
ended March 28, 1997.  Elcotel,  Inc., based in Sarasota,  Florida, is a leading
provider of smart payphone systems to domestic  private payphone  operators with
sales  revenues of $26.8 million for the fiscal year ended March 31, 1997.  Both
companies have also been  successful in marketing  products in foreign  markets.
TSG has  targeted  foreign  markets  with its wireless  payphone  systems  while
Elcotel has targeted foreign markets with its wireline payphone systems.

Under the terms of the Merger  Agreement,  TSG's  stockholders will receive 1.05
shares of Elcotel  common  stock,  par value  $.01 per share,  for each share of
TSG's common stock outstanding on the effective date of the Merger  irrespective
of the  trading  prices of the stocks on the  effective  date.  As of August 13,
1997, the Company had 4,708,476 shares of common stock outstanding,  and Elcotel
had  8,182,216  shares of common  stock  outstanding.  On August 13,  1997,  the
closing market price of TSG's common stock was $6.875 per share, and the closing
market price of Elcotel's common stock was $6.25 per share.

Vincent C. Bisceglia,  TSG's President and Chief Executive  Officer said,  "This
Merger will create a strong,  aggressive and powerful supplier of smart payphone
systems in the domestic  public  communications  industry.  It will position the
combined  company  to play a more  significant  role in the global  market,  and
should enhance shareholder value."

"Historically,   each  company  has  targeted   different  market  segments  and
therefore,  the combination is strategically and technologically  complementary.
The merged  companies  will be  well-positioned  to take advantage of the growth
opportunities in the United States created by the Telecommunications  Reform Act
of  1996  and  in  rapidly  expanding  foreign  telecommunication  markets  from
privatization   initiatives  that  are  creating   significant  demand  for  new
technology.  Our customers can be assured that the combined company's operations
will continue  without  interruptions  or delays in delivering  our products and
services since they will be working with the same dedicated  staff. The combined
business  will be  structured  to focus its  resources on each of its markets so
that we will continue to fulfill our respective customers' unique requirements."


                                      -5-

The completion of the Merger is subject to various  conditions,  including:  (i)
approval  of  the  stockholders  of  each  company;  (ii)  compliance  with  the
requirements of the Hart-Scott-Rodino  Antitrust Improvements Act of 1976; (iii)
the  listing  of the  shares  of  Elcotel's  common  stock to be  issued  in the
combination on the Nasdaq National  Market;  (iv) the  registration of shares of
Elcotel's  common stock to be issued in the  combination in accordance  with the
provisions of the  Securities  Act of 1933;  and (v) the execution of employment
agreements  with C. Shelton  James,  who will be Chairman,  and Tracey Gray, who
will be President  and Chief  Executive  Officer of the combined  entity and Mr.
Bisceglia, who will be its Executive Vice President and Chief Operating Officer.
In addition,  the Board of  Directors  will consist of five Elcotel and four TSG
nominees. The name of the combined entity will be announced at a later date.

Mr.  James  said,  "This  fulfills a  strategic  initiative  on the part of both
companies to diversify their  businesses and establish a strong presence in both
market  segments of the domestic  public  communications  industry.  At the same
time,  the companies  bring  together  complementary  coin,  card,  wireline and
wireless technology to address rapidly expanding foreign markets."

In connection with the Merger,  Wexford  Partners Fund,  L.P., which owns 52% of
TSG, and Fundamental Management  Corporation,  which owns 17.6% of Elcotel, will
enter into agreements that will include  provisions for each of them to vote for
the Merger and that restrict their sales of Elcotel securities after the Merger.

For its fiscal  year  ended  March 28,  1997,  TSG  reported  net income of $1.1
million, or $.22 per share. Elcotel reported net income of $1.6 million, or $.20
per share, for its fiscal year ended March 31, 1997.

                    5. Each  party  hereto  will,  either  prior to or after the
Effective Time,  execute such further  documents,  instruments,  deeds, bills of
sale, assignments and assurances and take such further actions as may reasonably
be requested by one or more of the others to consummate the Merger,  to vest the
Surviving  Corporation  with full title to all assets,  properties,  privileges,
rights, approvals,  immunities and franchises of Merger Subsidiary or TSG, or to
effect the other purposes of this Agreement.

                  Section B. Conversion of Shares.

                    1.  At the  Effective  Time by  virtue  of the  Merger,  and
without  any  action  on the part of the  holder of any  common  stock of TSG or
Merger Subsidiary:

                         a. each  share of  Common  Stock,  par value  $0.01 per
          share,  of TSG (the "TSG Common  Stock") held by TSG as treasury stock
          or owned by Elcotel or any Subsidiary of Elcotel  immediately prior to
          the Effective Time shall automatically be canceled and retired without
          any  conversion  thereof,   and  no  Elcotel  Common  Stock  or  other
          consideration shall be delivered in exchange therefor;

                         b. each  share of  common  stock,  par value  $0.01 per
          share,  of  Merger  Subsidiary  outstanding  immediately  prior to the
          Effective Time shall automatically be


                                      -16-
<PAGE>

         converted  into and become one share of common  stock of the  Surviving
         Corporation and shall constitute the only outstanding shares of capital
         stock of the Surviving Corporation; and

                         c. each share (each,  a "Share" and  collectively,  the
          "Shares") of TSG Common  Stock  outstanding  immediately  prior to the
          Effective  Time  shall,   except  as  otherwise  provided  in  Section
          1.02(a)(i),  automatically be converted into the right to receive 1.05
          shares of fully paid and non-assessable  Common Stock, par value $0.01
          per share of Elcotel (the "Elcotel Common Stock").

                    2. From and after the Effective  Time, all Shares  converted
in accordance with Section 1.02(a)(iii) shall no longer be outstanding and shall
automatically  be canceled and retired and shall cease to exist, and each holder
of a  certificate  representing  any such Shares  shall cease to have any rights
with respect thereto, except the right to receive the Merger Consideration. From
and after the Effective Time, all certificates  representing the common stock of
Merger  Subsidiary  shall be deemed for all purposes to represent  the number of
shares  of  Common  Stock of the  Surviving  Corporation  into  which  they were
converted in accordance with Section 1.02(a)(ii);

                    3. The Elcotel Common Stock to be received as  consideration
pursuant to the Merger by each holder of Shares  (together  with cash in lieu of
fractional  shares of Elcotel Common Stock) is referred to herein as the "Merger
Consideration"; and

                    4. For  purposes of this  Agreement,  the word  "Subsidiary"
when  used  with  respect  to  any  Person  means  any  other  Person,   whether
incorporated or  unincorporated,  of which at least a majority of the securities
or other interests having by their terms ordinary voting power to elect at least
a majority of the board of directors or others performing similar functions with
respect to such  corporation  or other  organization  is directly or  indirectly
owned or  controlled  by such Person or by any one or more of its  Subsidiaries.
For purposes of this Agreement,  "Person" means an individual, a corporation,  a
limited liability company, a partnership,  an association,  a trust or any other
entity or organization, including a Governmental Authority.

                  Section C.  Surrender and Payment.

                    1. Prior to the  Effective  Time,  Elcotel  shall appoint an
agent reasonably  satisfactory to TSG (the "Exchange  Agent") for the purpose of
exchanging  certificates  representing  Shares  for  the  Merger  Consideration.
Promptly  after the  Effective  Time (but in any event within five business days
thereafter),  Elcotel will send,  or will cause the Exchange  Agent to send,  to
each holder of Shares at the Effective Time (i) a letter of transmittal  for use
in such exchange (which shall specify that delivery of the Merger  Consideration
shall be effected,  and risk of loss and title to the certificates  representing
TSG Common  Stock shall  pass,  only upon  proper  delivery of the  certificates
representing  Shares to the  Exchange  Agent) and (ii)  instructions  for use in
effecting the surrender of the certificates  representing Shares in exchange for
the  certificates  representing  Elcotel  Common  Stock  and  cash  in  lieu  of
fractional  shares of  Elcotel  Common  Stock.  Notwithstanding  the  foregoing,
neither the  Exchange  Agent nor any party hereto shall be liable to a holder of
certificates  theretofore  representing  Shares  for  any  amount  which  may be
required to be paid to a public  official  pursuant to any applicable  abandoned
property, escheat or similar law;


                                      -17-
<PAGE>

                    2. Each  holder of Shares  that have been  converted  into a
right to receive the Merger Consideration,  upon surrender to the Exchange Agent
of a  certificate  or  certificates  representing  such Shares,  together with a
properly completed letter of transmittal  covering such Shares, will be entitled
to receive  the Merger  Consideration  payable in respect of such Shares and any
dividends payable pursuant to Section 1.03(f).  Until so surrendered,  each such
certificate shall, after the Effective Time, represent for all purposes only the
right to receive the Merger  Consideration and any dividends payable pursuant to
Section 1.03(f) and the holder thereof shall not be entitled to vote the Elcotel
Common Stock until such certificate is surrendered;

                    3. If any certificate  representing Merger  Consideration is
to be  delivered  to a Person  other  than the  registered  holder of the Shares
represented by the certificate or certificates surrendered in exchange therefor,
it shall be a condition to the issuance of such certificate  evidencing  Elcotel
Common  Stock that the  certificate  or  certificates  so  surrendered  shall be
properly  endorsed  or  otherwise  be in proper form for  transfer  and that the
Person  requesting  such payment shall pay to the Exchange Agent any transfer or
other taxes required by reason of the issuance of shares of Elcotel Common Stock
to a Person other than the registered  holder of such Shares  represented by the
certificate or certificates  so surrendered or establish to the  satisfaction of
the Exchange Agent that such tax has been paid or is not applicable;

                    4.  After the  Effective  Time,  there  shall be no  further
registration of transfers of Shares on the stock transfer book of TSG. If, after
the  Effective  Time,  certificates  representing  Shares are  presented  to the
Surviving   Corporation,   they  shall  be  canceled  and   exchanged   for  the
consideration  provided for, and in accordance with the procedures set forth, in
this Article I;

                    5. Any  portion of the  Merger  Consideration  that  remains
unclaimed by the holders of Shares six months after the Effective  Time shall be
returned to Elcotel,  upon demand, and any such holder who has not exchanged his
Shares for the Merger  Consideration  in accordance with this Section 1.03 prior
to that time shall  thereafter  look only to Elcotel  for  payment of the Merger
Consideration. Notwithstanding the foregoing, Elcotel shall not be liable to any
holder of Shares for any amount paid to a public official pursuant to applicable
abandoned  property laws. Any amounts  remaining  unclaimed by holders of Shares
seven years after the Effective Time (or such earlier date immediately  prior to
such time as such amounts would  otherwise  escheat to or become property of any
Governmental Authority) shall, to the extent permitted by applicable law, become
the  property of Elcotel  free and clear of any claims or interest of any Person
previously entitled thereto;

                    6. No  dividends  or other  distributions  with  respect  to
Elcotel  Common  Stock  issued in the Merger  shall be paid to the holder of any
unsurrendered  certificates  representing  Shares  until such  certificates  are
surrendered  as  provided  in  this  Section  1.03.  Subject  to the  effect  of
applicable laws,  following the surrender of such  certificates,  there shall be
paid, without interest,  to the record holder of the Elcotel Common Stock issued
in exchange  therefor at the time of such surrender,  the amount of dividends or
other distributions with a record date after the Effective Time payable prior to
or on the date of such  surrender  with  respect to such whole shares of Elcotel
Common Stock and not previously  paid, less the amount of any withholding  taxes
which may be required thereon;

                    7. In the event any  certificate  representing  Shares shall
have been lost, stolen or destroyed, upon the making of an affidavit of the fact
by the person claiming such certificate to be lost, stolen or destroyed, Elcotel
will,  after the  Effective  Time,  issue in exchange  for such lost,  stolen or
destroyed certificate the certificate  evidencing shares of Elcotel Common Stock
deliverable


                                      -18-
<PAGE>

in respect  thereof,  as  determined  in  accordance  with this  Article I. When
authorizing  such issue of the  certificate of shares of Elcotel Common Stock in
exchange therefor,  Elcotel may, in its discretion and as a condition  precedent
to the  issuance  thereof,  require the owner of such lost,  stolen or destroyed
certificate  to give  Elcotel a bond in such sum as it may  direct as  indemnity
against  any  claim  that  may be  made  against  Elcotel  with  respect  to the
certificate alleged to have been lost, stolen or destroyed; and

                    8.   Approval  and   adoption  of  this   Agreement  by  the
stockholders  of TSG  shall  constitute,  as an  integral  part  of the  Merger,
ratification  of the  appointment  of, and the  reappointment  of, said Exchange
Agent.

                  Section D.  Stock Option Plans.

                    1. At or before the  Effective  Time,  Elcotel and TSG shall
take such action as may be required to effect the  following:  the terms of each
outstanding option granted by TSG to purchase shares of TSG Common Stock (a "TSG
Stock Option") under the TSG 1994 Omnibus Stock Plan (the "Omnibus  Plan"),  the
TSG 1995 Employee  Stock Purchase Plan (the "Stock  Purchase  Plan") and the TSG
1995 Non-Employee Director Stock Option Plan (the "Director Plan," together with
the Omnibus  Plan and the Stock  Purchase  Plan,  collectively,  the "TSG Option
Plans"),  whether vested or unvested,  shall be adjusted as necessary to provide
that at the Effective Time, each TSG Stock Option outstanding  immediately prior
to the Effective  Time shall be deemed to constitute  and shall become an option
to acquire,  on the same terms and conditions as were applicable  under such TSG
Stock Option, the same number of shares of Elcotel Common Stock as the holder of
such TSG Stock Option would have been entitled to receive pursuant to the Merger
had such holder exercised such TSG Stock Option in full immediately prior to the
Effective  Time,  at a price per share of Elcotel  Common Stock equal to (i) the
aggregate   exercise  price  for  the  shares  of  TSG  Common  Stock  otherwise
purchasable  pursuant  to such TSG Stock  Option  divided by (ii) the  aggregate
number of shares of Elcotel Common Stock deemed purchasable pursuant to such TSG
Stock Option (each, as so adjusted, an "Adjusted Option");  provided that (after
aggregating  all the  Shares  of a holder  subject  to TSG  Stock  Options)  any
fractional  share of Elcotel Common Stock  resulting from such  calculation  for
such  holder  shall be  rounded  up to the  nearest  whole  share and  provided,
further, that in the case of any option to which Section 421 of the Code applies
by reason of its qualification under any of Sections 422 through 424 of the Code
("qualified stock options"),  the option price, the number of shares purchasable
pursuant to such option and the terms and  conditions of exercise of such option
shall be determined in order to comply with Section 424 of the Code;

                    2. As soon as practicable after the Effective Time,  Elcotel
shall deliver to the holders of TSG Stock Options  appropriate  notices  setting
forth such holders'  rights  pursuant to the respective TSG Option Plans and the
agreements  evidencing  the grants of such TSG Stock  Options  and that such TSG
Stock Options and  agreements  shall be assumed by Elcotel and shall continue in
effect on the same terms and conditions (subject to the adjustments  required by
this Section 1.04 after giving effect to the Merger); and

                    3.  Elcotel  shall  take  such  actions  as  are  reasonably
necessary for the  assumption  of the TSG Option Plans  pursuant to this Section
1.04, including the reservation, issuance and listing of Elcotel Common Stock as
is necessary to effectuate the  transactions  contemplated by this Section 1.04.
Elcotel shall prepare and file with the SEC a registration statement on Form S-8
or other appropriate form with respect to shares of Elcotel Common Stock subject
to TSG  Stock  Options  issued  under  such TSG  Option  Plans and shall use its
reasonable efforts to have such registration statement


                                      -19-
<PAGE>

declared  effective as soon as  practicable  following the Effective Time and to
maintain  the  effectiveness  of such  registration  statement  or  registration
statements  covering such TSG Stock Options (and maintain the current  status of
the prospectus or prospectuses  contained therein) for so long as such TSG Stock
Options remain outstanding.

                  Section E.  TSG Warrants.

                    1. At or before the  Effective  Time,  Elcotel and TSG shall
take such action in connection  with warrants to purchase  575,000 shares of TSG
Common Stock issued by TSG pursuant to that certain  warrant  agreement  between
TSG and Liberty Bank and Trust Company of Oklahoma  City,  N.A.  dated as of May
10,  1996  as may be  required  to  effect  the  following:  the  terms  of each
outstanding  warrant  to  purchase  shares of TSG  Common  Stock (a "TSG  Public
Warrant")  issued  pursuant  to such  warrant  agreement  shall be  adjusted  as
necessary  to  provide  that at the  Effective  Time,  each TSG  Public  Warrant
outstanding  immediately  prior  to  the  Effective  Time  shall  be  deemed  to
constitute  and shall  become a warrant to acquire,  on  substantially  the same
terms and conditions as were applicable under such TSG Public Warrant,  the same
number  of shares  of  Elcotel  Common  Stock as the  holder of such TSG  Public
Warrant  would have been  entitled  to receive  pursuant  to the Merger had such
holder  exercised  such TSG  Public  Warrant  in full  immediately  prior to the
Effective Time.

                    2. At or before the  Effective  Time,  Elcotel and TSG shall
take such action in connection  with the warrants to purchase  100,000 shares of
TSG Common Stock issued by TSG  pursuant to that certain  underwriter's  warrant
agreement between TSG and Brookehill Equities,  Inc. dated as of May 10, 1996 as
may be required to effect the following:  the terms of each outstanding  warrant
to purchase  shares of TSG Common  Stock (a "TSG  Underwriter  Warrant")  issued
pursuant to such underwriter's  warrant agreement shall be adjusted as necessary
to provide that at the Effective Time, each TSG Underwriter  Warrant outstanding
immediately  prior to the Effective Time shall be deemed to constitute and shall
become a warrant to acquire,  on substantially  the same terms and conditions as
were applicable under such TSG Underwriter Warrant, the same number of shares of
Elcotel  Common Stock as the holder of such TSG  Underwriter  Warrant would have
been entitled to receive  pursuant to the Merger had such holder  exercised such
TSG Underwriter Warrant in full immediately prior to the Effective Time.

                    Section F. Fractional Shares. Neither certificates nor scrip
for fractional shares of Elcotel Common Stock will be issued in the Merger,  but
in lieu thereof each holder of TSG Common Stock otherwise entitled to a fraction
of a share of Elcotel Common Stock (after  aggregating all fractional  shares of
TSG Common  Stock that would  otherwise  be  received  by such  holder)  will be
entitled  hereunder to receive a cash  payment.  The amount of such cash payment
shall equal,  in the case of each  fractional  share,  an amount (rounded to the
nearest  whole cent),  without  interest,  calculated as the product of (i) such
fraction, multiplied by (ii) the arithmetic mean of the closing sales prices for
the Elcotel Common Stock reported on the NASDAQ  National Market System for each
of the five (5)  consecutive  trading  days on which  Elcotel  Common  Stock was
traded  immediately  preceding the  Effective  Time as quoted in the Wall Street
Journal or other reliable financial  newspaper or publication.  For the purposes
of the  preceding  sentence,  a  "trading  day"  means  a day on  which  trading
generally takes place on the NASDAQ  National Market System.  No such fractional
share  interest  shall  entitle the owner  thereof to vote or to any rights of a
stockholder of Elcotel.

                            THE SURVIVING CORPORATION

                  Section A.  Certificate of  Incorporation.  The certificate of
incorporation of Merger  Subsidiary shall be the certificate of incorporation of
the Surviving  Corporation,  except that, at the Effective Time, the name of the
Surviving  Corporation  shall be  changed to "TSG" or such other name as Elcotel
may  designate on or before the  Effective  Time,  until  thereafter  amended in
accordance with applicable law and such certificate of incorporation.

                  Section B. Bylaws.  The bylaws of Merger  Subsidiary in effect
at the Effective  Time shall be the bylaws of the Surviving  Corporation,  until
thereafter  amended in  accordance  with  applicable  law,  the  certificate  of
incorporation of the Surviving Corporation and such bylaws.

                  Section  C.  Directors  and  Officers.   From  and  after  the
Effective Time,  until successors are duly elected or appointed and qualified in
accordance with the Delaware Law and the certificate of incorporation and bylaws

Corporation  shall be those persons set forth on Schedule 2.03 to the disclosure
letter delivered by Elcotel and Merger  Subsidiary to TSG concurrently  with the

                                  ARTICLE III.
                      REPRESENTATIONS AND WARRANTIES OF TSG

                  TSG represents and warrants to Elcotel that:

                  Section  A.  Organization  and  Power.  Each  of TSG  and  its
Subsidiaries  is a  corporation,  partnership  or other  entity duly  organized,
validly  existing and in good standing under the laws of the jurisdiction of its
incorporation  or organization,  and has the requisite  corporate or other power
and  authority  and  governmental  approvals  to  own,  lease  and  operate  its
properties and to carry on its business as now being conducted.  Each of TSG and
its  Subsidiaries  is duly  qualified  or licensed to do business and is in good
standing in each jurisdiction in which the property owned, leased or operated by
it or the nature of the  business  conducted by it makes such  qualification  or
licensing  necessary,  except  where  the  failure  to be so duly  qualified  or
licensed and in good standing would not, individually or in the aggregate,  have
a Material  Adverse Effect on TSG. For purposes of this  Agreement,  a "Material
Adverse  Effect" with respect to any Person means a material  adverse effect (i)
on the condition (financial or otherwise),  business,  liabilities,  properties,
assets,  results of operations or prospects of such Person and its Subsidiaries,
taken  as a  whole,  or (ii)  on the  ability  of such  Person  to  perform  its
obligations  under  or to  consummate  the  transactions  contemplated  by  this
Agreement.  Schedule 3.01 to the disclosure  letter  delivered by TSG to Elcotel
and Merger  Subsidiary  concurrently  with the  execution  and  delivery of this
Agreement (the "TSG Disclosure Letter") sets forth (i) the name and jurisdiction
of incorporation  of each Subsidiary of TSG, (ii) its authorized  capital stock,
(iii) the number of issued and outstanding shares of capital stock, and (iv) the
record and  beneficial  owners of such  shares.  Except as set forth on Schedule
3.01 to the TSG Disclosure  Letter,  TSG does not directly or indirectly own any
equity or similar interest in, or any interest  convertible into or exchangeable
or  exercisable  for,  any equity or similar  interest  in, any Person.  TSG has
heretofore  delivered to Elcotel true and complete  copies of the certificate or
articles  of  incorporation  and  bylaws as  currently  in effect of TSG and its
Subsidiaries.

transactions  contemplated  hereby are within TSG's corporate powers and, except
as set forth in the second  succeeding  sentence of this Section 3.02, have been
duly authorized by all necessary corporate action,  including without limitation
its Board of Directors.  The Board of Directors of TSG has recommended  approval
and adoption of this Agreement by the stockholders of TSG and directed that this
Agreement  be  submitted  to the  stockholders  of TSG for their  approval.  The
affirmative vote of a majority of the outstanding Shares is the only vote of any
class or series of TSG's  capital  stock  necessary  to  approve  and adopt this
Agreement and the  transactions  contemplated by this Agreement.  This Agreement
has been duly executed and  delivered by TSG and,  subject to the receipt of the
approval described in the immediately  preceding sentence,  constitutes a legal,
valid and binding agreement of TSG,  enforceable  against TSG in accordance with
its  terms  (subject  to  applicable  bankruptcy,  insolvency,   reorganization,
moratorium,  fraudulent  transfer and other  similar laws  affecting  creditors'
rights  generally  from  time to time in effect  and to  general  principles  of
equity, regardless of whether in a proceeding in equity or at law).

                  Section C. Governmental Authorization. The execution, delivery
and  performance by TSG of this  Agreement,  and the  consummation by TSG of the
transactions  contemplated  hereby,  require no action by or in  respect  of, or
filing with or notice to, any United States federal,  state or local government,
any  foreign  country,  any  foreign  state or local  government  or any  court,
administrative  agency or commission or other  governmental or regulatory agency
or authority of any of the foregoing  (collectively  "Governmental  Authorities"
and  individually a  "Governmental  Authority"),  other than (a) the filing of a
certificate of merger with respect to the Merger with the Delaware  Secretary of
State and appropriate documents with the relevant authorities of other states in
which TSG is  qualified  to do  business;  (b)  compliance  with any  applicable
requirements of the  Hart-Scott-Rodino  Antitrust  Improvements  Act of 1976, as
amended (the "HSR Act"); (c) compliance with any applicable  requirements of the
Securities Act of 1933, as amended,  and the rules and  regulations  promulgated
thereunder (the "1933 Act"); (d) compliance with any applicable  requirements of
the Securities  Exchange Act of 1934, as amended,  and the rules and regulations
promulgated   thereunder  (the  "1934  Act");  (e)  compliance  with  any  other
applicable  securities laws; and (f) those set forth on Schedule 3.03 to the TSG
Disclosure Letter.

                  Section D. Non-Contravention.  Except as set forth on Schedule
3.04 to the TSG Disclosure  Letter,  the execution,  delivery and performance by
TSG of this Agreement do not, and the  consummation  by TSG of the  transactions
contemplated  hereby  will not  require  the  consent  of any other  Person,  or
conflict with,  result in a violation or breach of,  constitute (with or without
notice  or lapse  of time or both) a  default  under,  result  in or give to any
Person  any  right  of  payment  or  reimbursement,  termination,  cancellation,
modification or acceleration  of, or result in the creation or imposition of any
Lien on any of the assets or properties of TSG or any of its Subsidiaries under,
any of the terms, conditions or provisions of (a) the certificate or articles of
incorporation,  bylaws or similar organizational  documents of TSG or any of its
Subsidiaries,  (b) assuming receipt of the approval of stockholders  referred to
in Section 3.02,  and compliance  with the matters  referred to in Section 3.03,
any  United  States or  foreign  statute,  law,  regulation,  rule or  ordinance
(together "Laws") or any judgment,  injunction,  order, writ, license, permit or
decree  of any  Governmental  Authority  (together  "Orders")  binding  upon  or
applicable to TSG, any  Subsidiary of TSG or any of their  respective  assets or
properties,  or (c) any note, bond,  mortgage,  security  agreement,  indenture,
lease,  contract,  instrument or other agreement of any kind to which TSG or any
Subsidiary of TSG is a party or by which TSG or any  Subsidiary of TSG or any of
their  respective  assets  or  properties  is bound (a "TSG  Agreement")  or any
license,  franchise,  permit or other similar  authorization  held by TSG or any
Subsidiary of TSG. For purposes of this Agreement, "Lien" means, with respect to
any asset, any


                                      -22-

mortgage,  lien, pledge, charge, security interest or encumbrance of any kind in
respect of such asset,  and,  in addition  with  respect to real  property,  any
easement, right of way or other restriction, limitation or burden of any kind in
respect of such real property.

                  Section E.   Capitalization of TSG.

                    1. The  authorized  capital stock of TSG consists  solely of
10,000,000 shares of TSG Common Stock and 100,000 shares of preferred stock, par
value $100.00 per share (the "TSG Preferred Stock"). As of the close of business
on July 31,  1997,  (i)  4,708,476  shares of TSG  Common  Stock are  issued and
outstanding,  no shares of TSG Common  Stock are issued and held in the treasury

Agreement  (including  Taxes  being  contested).  Neither  TSG  nor  any  of its
Subsidiaries  have any  material  liability  for any Taxes in excess of  amounts

                    4. The consummation of the transactions  contemplated hereby
will not result in the loss or impairment  of TSG's or any of its  Subsidiaries'
right to own or use any of the  Intellectual  Property  nor will it require  the
consent of any Governmental Authority or third party.

                    Section T. Labor Matters.  TSG has  previously  furnished to
Elcotel  true  and  complete  copies  of all  labor  and  collective  bargaining
agreements  to  which  TSG or any of its  Subsidiaries  is a party  and that are
currently  in effect,  together  with all  amendments  thereto  (if any).  Since
January 1, 1996, there have been no strikes,  slow downs or other work stoppages
or lockouts  involving any employees of TSG or any of its Subsidiaries and there
are no  disputes  by any labor  organization  in  progress or pending or, to the
knowledge of TSG,  threatened  against TSG or any of its Subsidiaries that would
have a  Material  Adverse  Effect  on  TSG.  TSG  and  its  Subsidiaries  are in
compliance in all material  respects with all applicable laws and regulations in
respect  of  employment  and  employment  practices,  terms  and  conditions  of
employment,  wages and hours,  occupational safety, health or welfare conditions
relating to premises occupied,  and civil rights. There are no charges of unfair
labor practices pending before any Governmental Authority involving or affecting
TSG or any of its  Subsidiaries.  As of the date of this Agreement,  there is no
representation  claim or petition  pending before the National  Labor  Relations
Board and, to the knowledge of TSG, no question concerning representation exists
with  respect to the  employees of TSG or any of its  Subsidiaries.  TSG has not
received notice that any customer or supplier of TSG or any or its  Subsidiaries
is  involved  in or  threatened  with or  affected  by any strike or other labor
disturbance  or dispute,  litigation or  administrative  proceeding or judgment,
order,  injunction,  decree or award,  the  consequences  of which  would have a
Material Adverse Effect on TSG.

                    Section  U.  Transactions  with  Affiliates.  Except  to the
extent  disclosed  in the TSG SEC  Documents  filed  prior  to the  date of this
Agreement,  none of the officers or directors of TSG or any of its  Subsidiaries
nor any of its Affiliates,  and, to its knowledge,  none of its key employees or
the key employees of any of its Subsidiaries, is a party to any transaction with
TSG or any of its Subsidiaries (other than for services as an employee,  officer
or  director  and other  than  transactions  between  TSG and one or more of its
direct or indirect  wholly owned  Subsidiaries  or between  such  Subsidiaries),
including,  without limitation, any contract, agreement or other arrangement (i)
providing for the  furnishing of services to or by, (ii) providing for rental of
real or personal property to or from, or (iii) otherwise  requiring  payments to
or from, any such officer,  director,  Affiliate or key employee,  any member of
the family of any such  officer,  director or key  employee or any  corporation,
partnership,  trust or other entity in which any such  officer,  director or key
employee has substantial  interest (excluding the ownership of not more than two
percent (2%) of the capital stock of a publicly traded  corporation) or which is
an Affiliate of such officer, director or key employee.

                    Section V.  Insurance.  Schedule 3.22 to the TSG  Disclosure
Letter  sets forth a  complete  and  accurate  list of all  primary,  excess and
umbrella policies, bonds and other forms of insurance currently owned or held by
or on  behalf  of  or  providing  insurance  coverage  to  TSG  or  any  of  its
Subsidiaries  and their  respective  businesses,  properties  and assets (or its
directors,  officers, agents or employees).  All such policies are in full force
and  effect.  Neither TSG nor any of its  Subsidiaries  has  received  notice of
default under any such policy,  or has received written notice of any pending or
threatened  termination or cancellation,  coverage  limitation or reduction,  or
material  premium  increase with respect to any such policy the failure of which
to maintain,  has a Material  Adverse  Effect on TSG.  Schedule  3.22 to the TSG
Disclosure  Letter  sets forth a  complete  and  accurate  summary of all of the
self-insurance  coverage  provided  by TSG or  any  of its  Subsidiaries  and no
letters of credit have been posted in respect thereof.

has duly and validly  approved the Merger,  this Agreement and the  transactions
contemplated  by this  Agreement  and such  approval  is  sufficient  to  render
inapplicable to the Merger, this Agreement, and the transactions contemplated by

federal laws in the United States (each, a "Takeover Statute") applicable to TSG
or any of its Subsidiaries is applicable to the Merger or the other transactions
contemplated hereby.

Letter sets forth a complete  list of Elcotel's  Subsidiaries,  all of which are

of Merger  Subsidiary and the Board of Directors of Elcotel,  in its capacity as

shares  contemplated by Sections 1.04 and 1.05),  constitutes a legal, valid and
binding agreement of each of Elcotel and Merger Subsidiary,  enforceable against
Elcotel  or Merger  Subsidiary,  as  applicable,  in  accordance  with its terms
(subject  to  applicable  bankruptcy,  insolvency,  reorganization,  moratorium,
fraudulent transfer and other similar laws affecting creditors' rights generally
from time to time in effect and to general principles of equity,

State and appropriate documents with the relevant authorities of other states in
which Merger  Subsidiary is qualified to do business;  (b)  compliance  with any
applicable  requirements  of the HSR Act;  (c)  compliance  with any  applicable

                    Section  D.  Non-Contravention.   Except  as  set  forth  on
Schedule 4.04 to the Elcotel  Disclosure  Letter,  the  execution,  delivery and
performance  by Elcotel and Merger  Subsidiary of this Agreement do not, and the
consummation by Elcotel and Merger  Subsidiary of the transactions  contemplated
hereby  will not  require the  consent of any other  Person,  or conflict  with,

of time or both) a default  under,  result in or give to any Person any right of

investigations  or audits  pending or, to the  knowledge of Elcotel,  threatened
against, relating to or affecting,  Elcotel or any of its Subsidiaries or any of
their respective assets or properties nor, to the knowledge of Elcotel, is there

                    1. All Tax Returns  required to be filed by Elcotel,  any of
its Subsidiaries, or any corporation that was included in the filing of a return
with Elcotel or its  Subsidiaries on a  consolidated,  combined or unitary basis
have been filed (the "Elcotel Tax  Returns") and all Taxes  required to be shown
on the Elcotel Tax Returns, or a subsequent  assessment with respect thereto, or
otherwise  due or payable (to the extent in excess of $50,000 in the  aggregate)
have been paid and any penalties  and interest  relating to such Taxes have been
paid. No other Taxes (to the extent in excess of $50,000 in the  aggregate)  are
payable by the Elcotel  Group with  respect to items or periods  covered by such
Tax Returns or with respect to Tax periods prior to the date of this  Agreement.
None  of the  Elcotel  Tax  Returns  contain,  or are  required  to  contain,  a
disclosure statement under Section 6662 of the Code, or any similar provision of
state, local or foreign law, with respect to any items that relate to Elcotel or
its  Subsidiaries  in order to avoid a penalty for any taxable year. All Elcotel
Tax Returns are true, correct and complete in all material respects. Elcotel has
made available to TSG correct and complete copies of all Elcotel Tax Returns for
all periods which are not closed by the statute of limitations.

                    2. No  adjustment  relating  to any  Elcotel Tax Returns has
been  proposed   formally  or,  to  Elcotel's   knowledge,   informally  by  any
Governmental  Authority  (to the extent in excess of $50,000 in the  aggregate),
and no basis exists for any such adjustment  that would have a Material  Adverse
Effect on TSG.  There are no outstanding  subpoenas or requests for  information
with  respect to any  Elcotel  Tax  Returns or  portions  thereof.  There are no
pending or, to Elcotel's  knowledge,  threatened  actions or proceedings for the
assessment or collection of Taxes for which Elcotel or its  Subsidiaries  may be
liable (to the extent in excess of $50,000 in the  aggregate).  There are no Tax
liens


                                      -39-
<PAGE>

on any assets of Elcotel or its Subsidiaries, except with respect to Taxes which
are not yet due and payable.

                    3. No  consent  under  Section  341(f)  of the Code has been
filed with respect to Elcotel or any of its  Subsidiaries.  Neither  Elcotel nor
any of its  Subsidiaries  is or has been subject to the dual  consolidated  loss
provisions of Section 1503 of the Code.

Elcotel  nor its  Subsidiaries  have  filed or  consented  to the  filing of any
Federal or state consolidated or combined return with any entity not a member of
the Elcotel Group.  Neither Elcotel nor any of its  Subsidiaries has been at any
time a member of any  partnership or joint venture or the holder of a beneficial
interest  in any trust for any Person for which the statute of  limitations  for
any Tax potentially applicable as a result of such membership or holding has not
expired.

                    5. Elcotel and its  Subsidiaries  have properly  accrued all
current or  contested  Taxes on their  books and  records,  and their  books and
records reflect  reserves that are adequate for the payment of all Taxes not yet
due and payable that are  properly  accruable  thereon  through the date of this
Agreement  (including  Taxes being  contested).  Neither  Elcotel nor any of its
Subsidiaries  have any  material  liability  for any Taxes in excess of  amounts
accrued  or  the  reserves  established.  All  Taxes  required  to be  withheld,
collected or deposited in  connection  with the  operations  and  activities  of
Elcotel or its Subsidiaries  have been timely  withheld,  collected or deposited
and, to the extent required, have been paid to the relevant taxing authority.

                    6.  Elcotel  does not own,  nor has it owned during the past
five years,  any of the capital  stock of TSG. At the Effective  Time,  the fair
market  value of the assets of Elcotel  will exceed the sum of its  liabilities,
plus the amount of other liabilities, if any, to which the assets are subject.

                    7. There are no  requests  for  rulings,  determinations  or
information  currently outstanding that could affect the Taxes of Elcotel or any
of its Subsidiaries.

                    8. The Elcotel Tax Returns  have been audited by the Service
or other governmental  agency (or closed by applicable  statutes of limitations)
and all Tax liabilities in respect thereof have been finally  determined for all
taxable  years  ending on or before  March 31,  1993.  There are no  outstanding
waivers or agreements  extending the statute of limitations  for any period with
respect to any Tax to which Elcotel or any of its Subsidiaries may be liable.

                    9. The term  "Elcotel  Group" shall mean,  individually  and
collectively,   (i)  Elcotel,  (ii)  its  Subsidiaries,  and  (iii)  any  trust,
corporation,  partnership  or  any  other  entity  as to  which  Elcotel  or its
Subsidiaries is liable for Taxes incurred by such entity either as a transferee,
or pursuant to Treasury  Regulations Section 1.1502-6,  or pursuant to any other
provision of federal, state, local or foreign law or regulations.

                    10.  Elcotel has made  available  to TSG a true and complete
copy of any: (i) elections, letter rulings and determination letters relating to
Taxes with respect to Elcotel or its Subsidiaries; and (ii) examination reports,
closing  agreements and statements of deficiencies for Taxes assessed against or

such plan so  qualifies,  and its trust is exempt from  taxation  under  Section

"accumulated funding deficiency",  as such term is defined in Section 412 of the
Code, whether or not waived;

                    4. Neither  Elcotel nor any ERISA Affiliate has incurred any

                    5.  With  respect  to each  Elcotel  Benefit  Plan that is a

medical or death benefits with respect to current or former employees of Elcotel
or any of its Subsidiaries beyond their termination of employment, other than as
required by law or on an employee-pay-all basis;

                    6. The consummation of the Merger pursuant to this Agreement

of  compensation  or benefits due to any individual  with respect to any Elcotel
Benefit Plan, or (ii)  constitute  or result in a prohibited  transaction  under
Section  4975 of the Code or  Section  406 or 407 of ERISA  with  respect to any
Elcotel Benefit Plan; and

plan", as such term is defined in Section 3(37) of ERISA, or which is covered by
Section 4063 or 4064 of ERISA.

approvals of all  Governmental  Authorities  necessary for the lawful conduct of

         of Elcotel  with  respect to any matters  relating to or arising out of

         previously  owned,  leased or operated by Elcotel or any  Subsidiary of
         Elcotel; and

                         c. there are no Environmental Liabilities.

                    2. For purposes of this Section 4.17, capitalized terms used
shall have the meanings assigned to them in Section 3.17(b),  except that in all
cases the word "Elcotel" shall be substituted for the word "TSG".

                    Section  R.  Assets.  The  assets,  properties,  rights  and
contracts, including (as applicable) title or leaseholds thereto, of Elcotel and
its  Subsidiaries,  taken as a whole,  are  sufficient to permit Elcotel and its
Subsidiaries  to  conduct  their   respective   businesses  as  currently  being
conducted.  All real property owned by Elcotel or its Subsidiaries is owned free
and clear of all Liens,  except (a) those  reflected or reserved  against in the
Elcotel  Balance  Sheet (or notes  thereto),  (b) taxes and  general and special
assessments  not in default and payable  without  penalty or  interest,  and (c)
Liens that do not  materially  adversely  interfere with any present use of such
property.

                  Section S.   Intellectual Property Rights.

                    1.  Elcotel  and its  Subsidiaries  own or have the right to
use, all Intellectual  Property individually or in the aggregate material to the
conduct of the businesses of Elcotel and its  Subsidiaries.  To the knowledge of
Elcotel,  (i) neither  Elcotel nor any  Subsidiary  of Elcotel is in default (or
with the  giving of notice or lapse of time or both would be in  default)  under
any license to use such Intellectual  Property,  (ii) such Intellectual Property
(other  than  patents)  is not being  infringed  by any third  party,  and (iii)
neither  Elcotel nor any  Subsidiary of Elcotel is infringing  any  intellectual
property of any third party. An accurate  schedule of all Intellectual  Property
of Elcotel or its  Subsidiaries  consisting of patents,  registered  trademarks,
registered  trade names and registered  copyrights and all pending  applications
therefor is set forth on Section 4.19 to the Elcotel Disclosure Letter;

                    2. Either  Elcotel or one of its  Subsidiaries  currently is
listed in the records of the appropriate United States,  state or foreign agency
as the sole owner of record for each  application and  registration  included in
the Intellectual Property,  other than Intellectual Property of which Elcotel or
its Subsidiaries is a licensee;

                    3.  Elcotel  and  its  Subsidiaries,  with  respect  to  all
Intellectual  Property  owned  thereby,  have  taken or  caused  to be taken all
reasonable steps in the exercise of reasonable  business  judgment to obtain and
retain valid and enforceable Intellectual Property rights therein, including the
submission  of  all  necessary   filings  in  accordance   with  the  legal  and
administrative requirements of the appropriate jurisdictions.  No application or
registration  listed on Schedule  4.19 to the Elcotel  Disclosure  Letter is the
subject  of any  pending,  existing  or,  to  Elcotel's  knowledge,  threatened,
opposition, interference, cancellation proceeding or other legal or governmental
proceeding before any registration authority in any jurisdiction; and

                    4. The consummation of the transactions  contemplated hereby
will  not  result  in  the  loss  or  impairment  of  Elcotel's  or  any  of its
Subsidiaries'  right to own or use any of the Intellectual  Property nor will it
require the consent of any Governmental Authority or third party.

                    Section T. Labor Matters.  Elcotel has previously  furnished
to  TSG  true  and  complete  copies  of all  labor  and  collective  bargaining
agreements to which Elcotel or any of its  Subsidiaries  is a party and that are
currently  in effect,  together  with all  amendments  thereto  (if any).  Since
January 1, 1996, there have been no strikes,  slow downs or other work stoppages
or lockouts  involving any employees of Elcotel or any of its  Subsidiaries  and
there are no  disputes by any labor  organization  in progress or pending or, to
the knowledge of Elcotel,  threatened against Elcotel or any of its Subsidiaries
that  would  have  a  Material  Adverse  Effect  on  Elcotel.  Elcotel  and  its
Subsidiaries are in compliance in all material respects with all applicable laws
and  regulations in respect of employment and  employment  practices,  terms and
conditions  of  employment,  wages and  hours,  occupational  safety,  health or
welfare conditions relating to premises occupied, and civil rights. There are no
charges of unfair labor  practices  pending  before any  Governmental  Authority
involving or  affecting  Elcotel or any of its  Subsidiaries.  As of the date of
this Agreement,  there is no representation claim or petition pending before the
National  Labor  Relations  Board and, to the knowledge of Elcotel,  no question
concerning representation exists with respect to the employees of Elcotel or any
of its  Subsidiaries.  Elcotel  has not  received  notice  that any  customer or
supplier of Elcotel or any or its Subsidiaries is involved in or threatened with
or affected by any strike or other labor  disturbance or dispute,  litigation or
administrative proceeding or judgment,  order, injunction,  decree or award, the
consequences of which would have a Material Adverse Effect on Elcotel.

                    Section  U.  Transactions  with  Affiliates.  Except  to the
extent  disclosed in the Elcotel SEC  Documents  filed prior to the date of this
Agreement,  none  of  the  officers  or  directors  of  Elcotel  or  any  of its
Subsidiaries nor any of its Affiliates,  and, to its knowledge,  none of its key
employees  or the key  employees of any of its  Subsidiaries,  is a party to any
transaction with Elcotel or any of its Subsidiaries  (other than for services as
an employee, officer or director and other than transactions between Elcotel and
one or more of its direct or indirect wholly owned  Subsidiaries or between such
Subsidiaries),  including,  without limitation, any contract, agreement or other
arrangement  (i)  providing  for  the  furnishing  of  services  to or by,  (ii)
providing for rental of real or personal property to or from, or (iii) otherwise
requiring  payments to or from,  any such  officer,  director,  Affiliate or key
employee, any member of the family of any such officer, director or key employee
or any  corporation,  partnership,  trust or  other  entity  in  which  any such
officer,  director or key  employee  has  substantial  interest  (excluding  the
ownership of not more than two percent  (2%) of the capital  stock of a publicly
traded  corporation)  or which is an Affiliate of such officer,  director or key
employee.

                    Section  V.   Insurance.   Schedule   4.22  to  the  Elcotel
Disclosure Letter sets forth a complete and accurate list of all primary, excess
and umbrella  policies,  bonds and other forms of insurance  currently  owned or
held by or on behalf of or providing insurance coverage to Elcotel or any of its
Subsidiaries  and their  respective  businesses,  properties  and assets (or its
directors,  officers, agents or employees).  All such policies are in full force
and effect.  Neither Elcotel nor any of its  Subsidiaries has received notice of
default under any such policy,  or has received written notice of any pending or
threatened  termination or cancellation,  coverage  limitation or reduction,  or
material  premium  increase with respect to any such policy the failure of which
to maintain,  has a Material  Adverse  Effect on Elcotel.  Schedule  4.22 to the
Elcotel Disclosure Letter sets forth a complete and


                                      -45-
<PAGE>

accurate summary of all of the  self-insurance  coverage  provided by Elcotel or
any of its  Subsidiaries  and no letters of credit  have been  posted in respect
thereof.

                    Section W.  Takeover  Statutes.  The Boards of  Directors of
Elcotel and Merger  Subsidiary have duly and validly  approved the Merger,  this
Agreement and the transactions  contemplated by this Agreement and such approval
is sufficient to render  inapplicable  to the Merger,  this  Agreement,  and the
transactions  contemplated  by this  Agreement  and the  Voting  Agreement,  the
provisions  of  Section  203 of the  Delaware  Law.  No other  Takeover  Statute
applicable to Elcotel or any of its  Subsidiaries is applicable to the Merger or
the other transactions contemplated hereby.

                    Section  X.  Finders'  Fees.  Except  for a fee  payable  to
Cameron  Associates,  a copy of whose engagement  agreement has been provided to
TSG, no investment banker, broker, finder, other intermediary or other Person is
entitled to any fee or commission from Elcotel or any Subsidiary of Elcotel upon
consummation of the transactions contemplated by this Agreement.

                    Section  Y.  Opinion  of  Financial  Advisor.   Elcotel  has
received the written  opinion of Murray,  Devine & Co. to the effect that, as of
the date  hereof,  the Merger  Consideration  to be  received  by the holders of
Shares in the Merger is fair to Elcotel from a financial point of view.  Elcotel
has delivered to TSG a copy of such opinion.

inform such parties of its


                                      -50-
<PAGE>

obligations under this Section;  and (c) it will notify Elcotel immediately (and
in no event later than 24 hours after  receipt of any  Alternative  Proposal) if
any such inquiries, proposals or offers are received by, any such information is
requested  from,  or any such  negotiations  or  discussions  are  sought  to be
initiated or continued with, it or any of such Persons; provided,  however, that
nothing  contained in this Section 5.03 shall prohibit the Board of Directors of
TSG from (i) furnishing  information to (but only pursuant to a  confidentiality
agreement  in  customary  form and  having  terms and  conditions  substantially
comparable to the  Confidentiality  Agreement) or entering into  discussions  or
negotiations  with any  person  or group  that  makes an  unsolicited  bona fide
Alternative  Proposal,  if,  and  only to the  extent  that,  (A) the  Board  of
Directors of TSG, based upon the written  opinion of outside  counsel (a copy of
which shall be provided promptly to Elcotel), determines in good faith that such
action is  required  for the Board of  Directors  to comply  with its  fiduciary
duties to  stockholders  imposed by Delaware Law, (B) prior to  furnishing  such
information to, or entering into  discussions or negotiations  with, such Person
or group,  TSG  provides  written  notice to Elcotel  to the  effect  that it is
furnishing  information to, or entering into  discussions or  negotiations  with
such Person or group,  and (C) TSG keeps Elcotel informed (which notice shall be
provided orally and in writing) of the status and material information including
the  identity of such Person or group with  respect to any such  discussions  or
negotiations  and any  Alternative  Proposal and the material  terms thereof and
gives  Elcotel  at least 24  hours'  advance  notice  of any  information  to be
supplied  to,  and at least 48  hours'  advance  notice of any  agreement  to be
entered into with,  any Person or group making such  Alternative  Proposal;  and

1934 Act with regard to an Alternative Proposal.

                  Section D.  Approval of Stockholders.

                    1. TSG shall,  through  its Board of  Directors,  duly call,
give  notice  of,  convene  and hold a  meeting  of its  stockholders  (the "TSG
Stockholders'  Meeting")  for the purpose of voting on the approval and adoption
of this Agreement and the Merger (the "TSG  Stockholders'  Approval") as soon as
reasonably  practicable  after the date  hereof.  Except as provided in the next
sentence, the Board of Directors of TSG shall recommend approval and adoption of
this  Agreement  and the Merger by the holders of TSG Common Stock and shall use
its best efforts to obtain such approval and adoption. The Board of Directors of
TSG shall be permitted  to (i) not  recommend to the holders of TSG Common Stock
that they give the TSG  Stockholders'  Approval or (ii)  withdraw or modify in a
manner adverse to Elcotel its  recommendation to the holders of TSG Common Stock
that they give the TSG Stockholders' Approval, but in each of cases (i) and (ii)
only if and to the extent that TSG has complied with Section 5.03 and a Superior
Proposal is pending at the time the TSG Board of  Directors  determines  to take
any such  action  or  inaction;  provided  that no such  failure  to  recommend,
withdrawal  or  modification  shall be made unless TSG shall have  delivered  to
Elcotel a written notice (a "Notice of Superior Proposal") advising Elcotel that
the Board of Directors of TSG has received a Superior  Proposal and  identifying
the Person or group  making  such  Superior  Proposal;  provided,  further  that
nothing  contained in this Agreement shall prevent the Board of Directors of TSG
from  complying with Rule 14e-2 under the 1934 Act with regard to an Alternative
Proposal.  For purposes of this  Agreement,  "Superior  Proposal" means any bona
fide Alternative  Proposal for at least a majority of the outstanding  Shares on
terms that the Board of Directors of TSG  determines in its good faith  judgment
(based on the advice of an independent reputable financial advisor,  taking into
account all the terms and conditions of the Alternative Proposal,  including any
break-up fees, expense reimbursement  provisions and conditions to consummation)
are more favorable and provide  greater value to all holders of TSG Common Stock
than this Agreement and the Merger taken as a whole;


                                      -51-
<PAGE>

                    2. Elcotel shall, through its Board of Directors, duly call,
give notice of,  convene and hold a meeting of its  stockholders  (the  "Elcotel
Stockholders'  Meeting" and,  together with the TSG Stockholders'  Meeting,  the
"Stockholders'  Meetings")  for the purpose of voting on the issuance of Elcotel
Common Stock in the Merger (the  "Elcotel  Stockholders'  Approval")  as soon as
reasonably  practicable after the date hereof. The Board of Directors of Elcotel
shall  recommend  that the  stockholders  of Elcotel  approve such  issuances of
Elcotel Common Stock, and shall use its best efforts to obtain such approval;

                    3.  Elcotel  and TSG shall  coordinate  and  cooperate  with
respect to the  timing of the  Stockholders'  Meetings  and shall use their best
efforts to cause the  Stockholders'  Meetings  to be held on the same day and as
soon as practicable after the date hereof.

                    Section E. Preparation of Form S-4 and Proxy Statement.  TSG
and  Elcotel  shall  prepare  and  file  with  the  SEC as  soon  as  reasonably
practicable  after the date  hereof,  the Proxy  Statement,  and  Elcotel  shall
prepare and file with the SEC as soon as reasonably practicable after such date,
the  Form  S-4 in  which  the  Proxy  Statement  will  be  included  within  the
prospectus.  Elcotel  and TSG shall use their best  efforts to have the Form S-4
declared  effective  by the SEC as promptly as  practicable  after such  filing.
Elcotel  shall  also  take  any  action  (other  than  qualifying  as a  foreign
corporation or taking any action which would subject it to service of process in
any jurisdiction  where Elcotel is not now so qualified or subject)  required to
be taken under  applicable  state blue sky or securities laws in connection with
the issuance of Elcotel  Common Stock in connection  with the Merger.  If at any
time prior to the Effective  Time any event shall occur that should be set forth
in an amendment of or a supplement  to the Form S-4,  Elcotel  shall prepare and
file  with  the SEC  such  amendment  or  supplement  as soon  thereafter  as is
reasonably practicable.  Elcotel, Merger Subsidiary and TSG shall cooperate with
each other in the  preparation  of the Form S-4 and the Proxy  Statement and any
amendment or supplement thereto,  and each shall notify the other of the receipt
of any  comments of the SEC with  respect to the Form S-4 and any  amendment  or
supplement thereto or for additional information, and shall provide to the other
promptly  copies of all  correspondence  between Elcotel or TSG, as the case may
be, with respect to the Form S-4 or the Proxy Statement.  Elcotel shall give TSG
and its  counsel the  opportunity  to review and comment on the Form S-4 and all
responses to requests for  additional  information by and replies to comments of
the SEC  before  their  being  filed  with,  or sent to,  the SEC.  Each of TSG,
Elcotel,   and  Merger  Subsidiary  agrees  to  use  its  best  efforts,   after
consultation  with the other  parties  hereto,  to respond  promptly to all such
comments of and requests by the SEC and to cause (x) the Form S-4 to be declared
effective by the SEC at the earliest  practicable  time and to be kept effective
as long as is necessary to consummate the Merger, and (y) the Proxy Statement to
be mailed to the holders of Elcotel  Common Stock and TSG Common Stock  entitled
to vote at the meetings of the  stockholders  of Elcotel and TSG at the earliest
practicable time.

                  Section F.  Access to Information.

                    1. To the extent  permitted by applicable law, from the date

advisors, auditors and other authorized representatives reasonable access during
normal business hours to the offices,  properties,  books and records of TSG and
its  Subsidiaries,  will furnish to Elcotel,  its counsel,  financial  advisors,
auditors and other authorized  representatives such financial and operating data

TSG's  employees,  auditors,  counsel and financial  advisors to cooperate  with
Elcotel  in its  investigation  of the  business  of TSG and  its  Subsidiaries;
provided  that no  investigation  pursuant  to this  Section  shall  affect  any
representation or warranty given

TSG in its  investigation  of the  business  of  Elcotel  and its  Subsidiaries,
provided  that no  investigation  pursuant  to this  Section  shall  affect  any
representation  or warranty given by Elcotel to TSG hereunder.  Such information
shall be held in confidence to the extent  required by, and in accordance  with,
the Confidentiality Agreement.

receive cash in lieu of fractional shares) to recognize gain or loss for federal
income tax purposes as a result of the  issuance of Elcotel  Common Stock in the

the transactions  contemplated  hereby may be abandoned at any time prior to the
Effective Time whether prior to or after Stockholders' Approval:

                    1. By  mutual  written  agreement  of TSG and  Elcotel  duly
authorized  by  action  taken by or on  behalf  of their  respective  Boards  of
Directors;

non-terminating party by the terminating party;

                         a. at any time after  November  30,  1997 if the Merger
         shall  not have  been  consummated  on or  prior to such  date and such
         failure to  consummate  the  Merger is not  caused by or  substantially
         attributable to a breach of this Agreement by the terminating party;

                         b. if (A) TSG  Stockholders'  Approval  (under Delaware
         Law) or (B) Elcotel  Stockholders'  Approval  (under  Delaware  Law and
         under the applicable  regulations of NASDAQ National Market System), as
         the case may be,  shall not be  obtained  by reason of the  failure  to

         stockholders, or any adjournment thereof, called therefor;

                         c. if (A)  there  has  been a  material  breach  of any
         representation,  warranty,  covenant  or  agreement  on the part of the
         non-terminating party set forth in this Agreement,  which breach is not
         curable  or, if  curable,  has not been cured  within  thirty (30) days
         following receipt by the non-terminating party of notice of such breach
         from the  terminating  party,  or (B) any  condition  precedent  to the
         terminating  party's obligations set forth in Article VII, with respect
         to Elcotel, or Article VIII, with respect to TSG, of this Agreement has
         not been met or waived by such party by November 30, 1997; or

                         d. if any  court  of  competent  jurisdiction  or other
         competent  Governmental  Authority  shall have  issued an order  making
         illegal or otherwise restricting,  preventing or prohibiting the Merger
         and such order shall have become final and nonappealable;

                    3. By TSG if (i) the Board of Directors of TSG determines in
good faith,  based upon the written  opinion of outside counsel (a copy of which
shall be provided  promptly to Elcotel),  that  termination  of the Agreement is
required  for the Board of  Directors  to comply  with its  fiduciary  duties to
stockholders  imposed  by law by reason  of an  unsolicited  bona fide  Superior
Proposal  having  been  made;  provided  that TSG shall have  complied  with the
provisions  of clauses (B) and (C) of Section 5.03 and shall  notify  Elcotel at
least 48 hours in advance of its intention to terminate  this Agreement or enter
into a definitive agreement with respect to such Superior Proposal;  or (ii) the
Board of  Directors  of Elcotel  shall have  withdrawn  or  modified in a manner
materially  adverse to TSG its approval or  recommendation  of this Agreement or
the Merger; or

                    4. By  Elcotel  if the Board of  Directors  of TSG (x) shall
have  withdrawn  or  modified  in a manner  materially  adverse to  Elcotel  its
approval or  recommendation  of this  Agreement  or the Merger or (y) shall have
recommended a Superior Proposal to the stockholders of TSG or shall have entered
into a definitive  agreement  providing  for a Superior  Proposal  with a Person
other than Elcotel.

                  Section B.   Effect of Termination.

                    1. If this Agreement is validly  terminated by either TSG or
Elcotel  pursuant to Section 9.01, this Agreement will forthwith become null and
void and there will be no liability or  obligation  on the part of either TSG or
Elcotel (or any of their respective  representatives or Affiliates),  except (i)
that the  provisions  of Sections  10.05 and 10.08,  this  Section  9.02 and the
Confidentiality Agreement will continue to apply following any such termination,
(ii) that nothing contained herein shall relieve any party hereto from liability
for wilful breach of its  representations,  warranties,  covenants or agreements
contained in this  Agreement and (iii) as provided in paragraph  (b) below.  The
effectiveness  of any  termination  under this Agreement shall be subject to the
payments (if any)  required to be made  pursuant to paragraph (b) below being so
made;

                         2.  (i) If  this  Agreement  is  terminated  by (x) TSG
         pursuant to Section  9.01(c)(i)  or (y) by Elcotel  pursuant to Section
         9.01(d)(y),  then TSG shall pay or cause to be paid to Elcotel, by wire
         transfer  of  same  day  funds  on  the  day  of  such  termination,  a
         termination fee of $1,300,000;

                         (ii) In the event that (x) this Agreement is terminated
         by either party  pursuant to Section  9.01(b)(ii)(A)  and prior to such
         termination any person or group shall have made an Alternative Proposal
         or by Elcotel  pursuant  to Section  9.01(d)(x),  then TSG shall pay or
         cause to be paid to  Elcotel,  by wire  transfer of same day funds upon
         receipt of appropriate  documentation  therefor,  Elcotel's  documented
         out-of-pocket  expenses relating to this Agreement and the transactions
         contemplated hereby;  provided,  however,  that such expenses shall not
         exceed $500,000;

                         (iii) In the event that this Agreement is terminated by
         either party pursuant to Section  9.01(b)(ii)(B)  or by TSG pursuant to
         Section 9.01(c)(ii), then Elcotel shall pay or cause to be paid to TSG,
         by wire transfer of same day funds upon receipt of appropriate


                                      -59-
<PAGE>

         documentation   therefor,   TSG's  documented   out-of-pocket  expenses
         relating to this Agreement and the  transactions  contemplated  hereby;
         provided however, that such expenses shall not exceed $500,000;

                         (iv) In the event that this  Agreement is terminated by
         either party pursuant to Section 9.01(b)(iii), then the non-terminating
         party  shall pay or cause to be paid to the  terminating  party by wire
         transfer of same day funds upon  receipt of  appropriate  documentation
         therefor,  the terminating  party's documented  out-of-pocket  expenses
         relating to this Agreement and the  transactions  contemplated  hereby;
         provided, however, that such expenses shall not exceed $500,000; and

                    3. The parties acknowledge that the agreements  contained in
this Section 9.02 are an integral part of the transactions  contemplated by this
Agreement,  and that,  without these  agreements,  the parties  hereto would not
enter into this  Agreement;  accordingly,  if either party fails promptly to pay
the  amount due  pursuant  to this  Section  9.02,  and in order to obtain  such
payment,  either party commences a suit which results in a judgment  against the
non-paying party for any fee or expense  reimbursement set forth in this Section
9.02, the non-paying  party shall pay to the other party as the case may be, its
cost  and  expenses  (including  reasonable  attorney's  fees and  expenses)  in
connection  with such suit,  together  with interest on the amount of the fee at
the prime rate of Citibank, N.A. in effect on the date such payment was required
to be made.

                    (b) Authorization.  This Agreement has been duly and validly
executed and delivered by Wexford and constitutes a valid and binding  agreement

contemplated  hereby  and  (ii)  none  of the  execution  and  delivery  of this
Agreement  by  Wexford,   the   consummation  by  Wexford  of  the  transactions
contemplated  hereby or compliance by Wexford with any of the provisions  hereof
will (A) conflict with or result in any breach of the  organizational  documents
of  Wexford,  (B) result in a  violation  or breach of, or  constitute  (with or
without  notice or lapse of time or both) a  default  (or give rise to any third
party right of termination, cancellation, material modification or acceleration)
under any of the terms,  conditions or provisions of any note,  loan  agreement,
bond,  mortgage,   indenture,   license,  contract,   commitment,   arrangement,
understanding,  agreement or other instrument or obligation of any kind to which
Wexford is a party or by which Wexford or any of its properties or assets may be
bound, or (C) violate any order, writ, injunction,  decree,  judgment,  statute,

                    (d) No Encumbrances. Except as applicable in connection with
the  transactions  contemplated  by Section 1 hereof,  the Wexford Shares at all
times  during  the term  hereof,  will be,  beneficially  owned by  Wexford  and

all liens,  claims,  security interests,  proxies,  voting trusts or agreements,
understandings or arrangements or any other encumbrances whatsoever,  except for
any such matters arising hereunder.

                    (e) No  Finder's  Fees.  Except as set  forth in the  Merger
Agreement,  no broker,  investment banker,  financial advisor or other person is
entitled to any broker's,  finder's, financial adviser's or other similar fee or

based upon arrangements made by or on behalf of Wexford.

                    (f) Restriction on Transfer,  Proxies and  Non-Interference.

or enter into any contract,  option or other  arrangement or understanding  with
respect to or consent to the offer for sale,  sale,  transfer,  tender,  pledge,
encumbrance,  assignment  or other  disposition  of,  any or all of the  Wexford

obligations under this Agreement.

Wexford has reviewed  such  information  which  Wexford  considers  necessary or
appropriate  to evaluate  the risks and merits of an  investment  in the Elcotel

representatives  of  Elcotel  so as to receive  answers  and verify  information
obtained in its examination of Elcotel, including the information referred to in
this paragraph and any other documents or information  that Wexford has reviewed
in relation to its proposed  investment in Elcotel  Common Stock pursuant to the
Merger.  No oral or  written  representations  have  been  made  to  Wexford  in
connection  with  Wexford's  proposed  acquisition of Elcotel Common Stock which
were in any way inconsistent with the information reviewed by Wexford.

                    (h) Independent Decision.  Wexford is not relying on Elcotel
with respect to the tax considerations of Wexford relating to Wexford's proposed
investment in the Elcotel Common

Stock. Wexford has relied solely on the representations,  warranties,  covenants
and  agreements of Elcotel in the Merger  Agreement  (including the Exhibits and
Schedules thereto) and on Wexford's  examination and independent  investigation,
and on the answers and information  supplied pursuant to paragraph (g) above, in
making its decision to acquire Elcotel Common Stock.

                    SECTION 4.  COVENANTS,  REPRESENTATIONS  AND  WARRANTIES  OF
FUNDAMENTAL.  Fundamental  hereby  represents  and warrants to, and agrees with,

laws affecting creditors rights and (ii) that the remedy of specific performance
and injunctive  and other forms of equitable  relief may be subject to equitable
defenses and to the discretion of the court before which any proceeding therefor
may be brought.

                    (c)  No  Conflicts.  Except  for  filings,   authorizations,
consents and  approvals  as may be required  under the HSR Act, the 1933 Act and
the 1934 Act,  (i) no filing  with,  and no  permit,  authorization,  consent or
approval of, any state or federal  Governmental  Authority is necessary  for the
execution of this Agreement by Fundamental  and the  consummation by Fundamental
of the  transactions  contemplated  hereby  and (ii) none of the  execution  and
delivery of this Agreement by  Fundamental,  the  consummation by Fundamental of
the  transactions  contemplated  hereby or compliance by Fundamental with any of
the  provisions  hereof  will (A)  conflict  with or result in any breach of the
organizational documents of Fundamental, (B) result in a violation or breach of,
or  constitute  (with or without  notice or lapse of time or both) a default (or
give  rise to any  third  party  right of  termination,  cancellation,  material
modification or acceleration)  under any of the terms,  conditions or provisions
of any note, loan  agreement,  bond,  mortgage,  indenture,  license,  contract,
commitment,  arrangement,   understanding,  agreement  or  other  instrument  or
obligation of any kind to which  Fundamental is a party or by which  Fundamental
or any of its properties or assets may be bound, or (C) violate any order, writ,
injunction,   decree,  judgment,  statute,  rule  or  regulation  applicable  to

entitled to any broker's,  finder's, financial adviser's or other similar fee or
commission in connection  with the  transactions  contemplated by this Agreement
based upon arrangements made by or on behalf of Fundamental.

                    (f) Restriction on Transfer,  Proxies and  Non-Interference.

termination  of this  Agreement,  (i) except as permitted by Section 2(i) above,

dispose  of,  or enter  into  any  contract,  option  or  other  arrangement  or
understanding with respect to or consent to the offer for sale, sale,  transfer,

the Fundamental Shares or any interest therein; (ii) grant any proxies or powers
of attorney,  deposit the Fundamental Shares into a voting trust or enter into a

                    SECTION 6. AFFILIATE'S LETTER. Wexford will duly execute and
deliver to Elcotel an Affiliate's Letter prior to the Effective Time.

                    SECTION 7.  TERMINATION.  This Agreement will terminate upon
the earlier of (i) the  consummation  of the Merger and (ii) the  termination of
the Merger Agreement in accordance with its terms.

                    SECTION 8. MISCELLANEOUS.

                    (a) Entire Agreement.  This Agreement constitutes the entire
agreement  among the  parties  with  respect to the  subject  matter  hereof and
supersedes all other prior agreements and understandings, both written and oral,
between the parties with respect to the subject matter hereof.

                    (b)  Survival  of   Representations   and  Warranties.   The
representations  and warranties of the parties hereto contained in Sections 3, 4
and 5 of this Agreement shall survive the Closing.

                    (c)   Assignments;   Rights  of   Assignees;   Third   Party
Beneficiaries.  This  Agreement  shall not be  assignable  by any  party  hereto
without the consent of the other parties.  This Agreement shall be binding upon,
inure to the benefit  of, and be  enforceable  by, the parties  hereto and their
estates,  legal  representatives,  successors  and  permitted  assigns.  Nothing
expressed or referred to in this  Agreement is intended or shall be construed to
give any person  other than the parties to this  Agreement  or their  respective
estates,  legal representatives and/or successors or permitted assigns any legal
or equitable right, remedy or claim under or in respect of this Agreement or any
provision contained herein.

                    (d) Specific  Performance.  The parties  hereto  acknowledge
that money damages are an inadequate remedy for breach of this Agreement because
of the difficulty of ascertaining  the amount of damage that will be suffered by
the non-breaching party or parties in the event that this Agreement is breached.
Therefore,  each of the  Stockholders  agrees  that the  non-breaching  party or
parties may obtain specific  performance of this Agreement and injunctive relief
against any breach  hereof  without the  necessity of  establishing  irreparable
harm.

                    (e) Waiver.  No waiver of any  provision  of this  Agreement
shall be  effective  unless it is in writing  signed by the party  granting  the
waiver,  and a waiver by any party hereto of any one or more defaults  shall not
operate as a waiver of any future default or defaults, whether of a like or of a
different character.  No waiver of any of the provisions of this Agreement shall
constitute a waiver of any other provisions (whether or not similar),  nor shall
such a  waiver  constitute  a  continuing  waiver,  unless  otherwise  expressly
provided.

                    (f) Section Headings.  Headings  contained in this Agreement
are inserted only as a matter of  convenience  and in no way define,  limit,  or
extend the scope or intent of this Agreement or any provisions thereof.

                    (g) Choice of Law.  This  Agreement  will be governed by and
construed  and  enforced  in  accordance  with the laws of the State of Delaware
(without  regard to the principles of conflicts of law) applicable to a contract
executed  and to be  performed  in such state.  Each party  hereto (i) agrees to
submit to personal  jurisdiction  and to waive any  objection as to venue in the
state or federal courts  located in the State of Delaware,  (ii) agrees that any
action or proceeding shall be brought exclusively in such courts, unless subject
matter jurisdiction or personal jurisdiction cannot


                                      -70-
<PAGE>

be  obtained,  and (iii) agrees that service of process on any party in any such
action shall be effective if made by registered or certified  mail  addressed to
such party at the address  specified  herein,  or to any parties  hereto at such
other  addresses  as it may from time to time  specify  to the other  parties in
writing  for such  purpose.  The  exclusive  choice  of forum  set forth in this
Section  8(g) shall not be deemed to preclude  the  enforcement  of any judgment
obtained  in such  forum or the taking of any action  under  this  Agreement  to
enforce such judgment in any appropriate jurisdiction.

                    (h) Notices. All notices,  requests and other communications
to any party  hereunder shall be in writing and will be deemed to have been duly
given only if delivered personally or by facsimile transmission or mailed (first
class mail postage prepaid), or by overnight express courier (charges prepaid or
billed to the account of the sender) to the parties at the  following  addresses
