international private payphone operators and telcos providing public
communications services. Elcotel is one of the leaders in sales of
microprocessor-based payphone products to domestic private payphone operators.
Elcotel's payphones support coin, credit card and debit card applications and
are controlled internally by a microprocessor, memory chips, and other
electronic components which automate the call management functions performed by
the payphone.

                                   THE MERGER
 
  At the effective time of the Merger ("Effective Time"), Merger Subsidiary
will merge into TSG, with TSG as the surviving corporation of the Merger. As a
result of the Merger, TSG will become a wholly-owned subsidiary of Elcotel. The
Effective Time of the Merger will be at such time as the certificate of merger
is filed with the Delaware Secretary of State, or at such subsequent date or
time as Elcotel and TSG agree and specify in the certificate of merger. The
filing of the certificate of merger will occur no later than the fifth business
day after satisfaction or waiver of the conditions to the consummation of the
Merger set forth in the Merger Agreement unless another date is agreed to in
writing by TSG, Elcotel and Merger Subsidiary (the "Closing Date").
 
THE MERGER CONSIDERATION
 
  At the Effective Time of the Merger, each share of TSG Common Stock issued
and outstanding immediately prior to the Effective Time (other than shares of
TSG Common Stock owned by TSG as treasury stock and shares of TSG Common Stock
owned by Elcotel or any direct or indirect wholly-owned subsidiary of Elcotel
or TSG) will by virtue of the Merger and without any action on the part of the
holder thereof be automatically converted into the right to receive 1.05 fully
paid and nonassessable shares of Elcotel Common Stock. No fractional shares of
Elcotel Common Stock will be issued in connection with the Merger. In lieu of
any fractional shares, Elcotel will pay to each holder of TSG Common Stock
otherwise entitled to receive a fractional share, an amount in cash equal to
such fraction multiplied by the arithmetic mean of the closing sales prices for
Elcotel Common Stock reported on the Nasdaq National Market for each of the
five consecutive trading days on which Elcotel Common Stock was traded
immediately preceding the Effective Time. See "The Merger Agreement--Conversion
of TSG Shares." Holders of options and rights to purchase shares of TSG Common
Stock ("TSG Stock Options") pursuant to TSG's option and stock purchase plans
will receive options and rights to purchase, at a proportionately reduced per
share exercise price, a number of shares of Elcotel Common Stock equal to 1.05
times the number of shares of TSG Common Stock they were entitled to purchase
immediately prior to the Effective Time under such TSG Stock Options. See "The
Merger Agreement--Conversion of Options to Purchase TSG Common Stock." Holders
of warrants to purchase TSG Common Stock ("TSG Warrants") will receive warrants
to purchase, at a proportionately reduced per share exercise price, a number of
shares of Elcotel Common Stock equal to 1.05 times the number of shares of TSG
Common Stock they were entitled to purchase immediately prior to the Effective
Time under such TSG Warrants. See "The Merger Agreement--Conversion of Warrants
to Purchase TSG Common Stock."
 
TERMINATION
 
  The Merger Agreement may be terminated before the effective time
notwithstanding approval by the stockholders of Elcotel or TSG, under the
circumstances specified in the Merger Agreement, including by mutual written
agreement of Elcotel and TSG and termination by either party if the Merger is
not consummated by December 31, 1997. See "The Merger Agreement--Termination."
 
TERMINATION FEES AND EXPENSES
 
  Under certain circumstances, either Elcotel or TSG may be required to pay a
termination fee or to reimburse the other party for its reasonable out-of-
pocket expenses if the Merger is not consummated. Under certain circumstances
Elcotel may be required to reimburse TSG for certain costs if the Merger is not
consummated. See "The Merger Agreement--Termination Fees and Expenses."
 
RECOMMENDATION OF THE ELCOTEL BOARD
 
  The Elcotel Board has approved the Merger Agreement and recommends that the
stockholders of Elcotel vote FOR the approval of the issuance of Elcotel Common
Stock pursuant to the Merger Agreement and any
 
                                       7
<PAGE>
 
other actions required in furtherance of the Merger. For a discussion of the
factors considered by the Elcotel Board in reaching its conclusions, see "The
Merger--Elcotel's Reasons for the Merger; Recommendation of the Elcotel Board."
 
OPINION OF ELCOTEL'S FINANCIAL ADVISOR
 
  In determining to approve the Merger Agreement, the Elcotel Board considered,
among other factors, the oral opinion, confirmed in a written opinion dated
August 5, 1997, of Murray, Devine & Co. ("Murray Devine") to the effect that as
of such date the Merger is fair to the stockholders of Elcotel from a financial
point of view. The full text of the Murray Devine opinion, which sets forth a
description of the assumptions made, matters considered and limitations on the
review undertaken, is attached to this Joint Proxy Statement-Prospectus as
Appendix B. Elcotel stockholders are urged to read the Murray Devine opinion
carefully in its entirety. The Merger Agreement does not require that such
opinion be updated prior to the Effective Time. See "The Merger--Opinion of
Murray Devine."
 
RECOMMENDATION OF THE TSG BOARD
 
  The TSG Board has approved the Merger Agreement and recommends that the
stockholders of TSG vote FOR the adoption of the Merger Agreement and any other
actions as may be required in furtherance of the Merger. For a discussion of
the factors considered by the TSG Board in reaching its conclusions, see "The
Merger--TSG's Reasons for the Merger; Recommendation of the TSG Board."
 
INTERESTS OF CERTAIN PERSONS
 
  In considering the recommendations of the Elcotel Board and the TSG Board
with respect to the Merger and the transactions contemplated thereby, holders
of Elcotel Common Stock and of TSG Common Stock, respectively, should be aware
that certain members of Elcotel's and TSG's management and of the Elcotel Board
and the TSG Board have certain interests in the Merger that are in addition to
the interests of stockholders of Elcotel and TSG generally, including, among
other things, (i) the conversion pursuant to the Merger Agreement of the TSG
Stock Options into options to acquire Elcotel Common Stock, with adjustments to
the exercise price per share and number of shares subject thereto based on the
Exchange Ratio, and their immediate exercisability as a result of the Merger,
pursuant to the terms of the plans governing the TSG Stock Options (the "TSG
Option Plans") and stock option agreements, whether or not such TSG Stock
Options were exercisable immediately prior to the Effective Time; (ii) the
payment of a $200,000 investment banking fee to an affiliate of Wexford, the
holder of approximately 52% of the outstanding TSG Common Stock; and (iii) the
employment agreements that Elcotel will enter into with C. Shelton James, the
Chief Executive Officer and Chairman of the Board of Elcotel, Tracey Gray, the
President of Elcotel, and Vincent Bisceglia, the President and Chief Executive
Officer of TSG, in connection with the Merger. See "The Merger--Interests of
Certain Persons and Employee Matters."
 
CERTAIN FEDERAL INCOME TAX CONSEQUENCES
 
  The Merger is intended to be a tax-free reorganization as a result of which
no income, gain or loss will be recognized by Elcotel or TSG and no income,
gain or loss will be recognized by TSG stockholders upon exchange of their TSG
Common Stock for Elcotel Common Stock pursuant to the Merger Agreement, except
in respect of cash received by holders of TSG Common Stock in lieu of
fractional shares of Elcotel Common Stock. It is a condition precedent to the
obligations of TSG pursuant to the Merger Agreement that TSG receive an opinion
of counsel to the effect that neither TSG nor any of its stockholders will
recognize gain or loss for United States federal income tax purposes as a
result of the Merger (other than in respect of any cash paid in lieu of
fractional shares). See "The Merger--Certain Federal Income Tax Consequences"
and "The Merger Agreement--Conditions Precedent to Obligations of TSG."
 
                                       8
<PAGE>
 
 
ACCOUNTING TREATMENT
 
  The Merger will be accounted for by Elcotel under the "purchase" method of
accounting. Accordingly, the merger consideration will be allocated to the
assets and liabilities of TSG based on their estimated fair values with the
excess recorded as goodwill. See "Unaudited Pro Forma Consolidated Financial
Information."
 
NO APPRAISAL OR DISSENTERS' RIGHTS
 
  Under the Delaware General Corporation Law ("Delaware Law"), neither the
holders of Elcotel Common Stock nor the holders of TSG Common Stock are
entitled to appraisal or dissenters' rights in connection with the approval of
the Merger Agreement and the transactions contemplated thereby. See "The
Merger--No Appraisal or Dissenters' Rights."
 
                              RECENT DEVELOPMENTS
 
  On September 30, 1997, Elcotel acquired from Lucent Technologies Inc.
("Lucent") certain assets related to Lucent's payphone manufacturing and
component parts business (the "Lucent Acquisition"). The purchase price was
approximately $6 million, subject to adjustment based upon a final inventory
valuation. See "Unaudited Pro Forma Financial Information--Lucent Acquisition
Purchase Price." Elcotel acquired from Lucent the inventory, machinery,
equipment, tooling and certain other assets related to the payphone
manufacturing and component parts business conducted by Lucent, as well as a
license of certain patent and other intellectual property rights related
thereto. Elcotel did not acquire any employees or facilities of Lucent pursuant
to such acquisition. The customers for Lucent's payphones and component parts
consisted principally of RBOCs and other telcos. Elcotel believes that
approximately 60% (approximately 1.2 million units) of the current installed
base of payphones in the United States are payphones of the design purchased by
Elcotel pursuant to the Lucent Acquisition. Elcotel believes that a significant
part of the revenues that may arise from the assets acquired by Elcotel
pursuant to the Lucent Acquisition will consist of the sale of components and
replacement parts with respect to that installed base of payphones.

    adding the number of shares of Elcotel Common Stock to be issued in
    connection with the Merger to the actual number of outstanding shares of
    Elcotel Common Stock for the respective periods.
(2) Equivalent pro forma per share amounts have been calculated by multiplying
    the Elcotel pro forma per share amounts by the Exchange Ratio of 1.05 of
    Elcotel Common Stock for each share of TSG Common Stock.

    SELECTED HISTORICAL AND PRO FORMA CONSOLIDATED FINANCIAL DATA OF ELCOTEL
 
  The following table sets forth certain selected consolidated financial data
of Elcotel for the year ended March 31, 1997 and as of and for the three months
ended June 30, 1997 and certain selected unaudited pro forma consolidated
financial information of Elcotel for the year ended March 31, 1997 and as of
and for the three months ended June 30, 1997 after giving effect to the Merger
and the Lucent Acquisition. The selected consolidated historical financial data
and the selected unaudited pro forma consolidated financial information of
Elcotel presented below should be read in conjunction with the consolidated
financial statements, including the notes thereto, of Elcotel set forth in
Elcotel's Annual Report on Form 10-K for the fiscal year ended March 31, 1997
and Elcotel's Quarterly Report on Form 10-Q for the fiscal quarter ended June
30, 1997 incorporated in this Joint Proxy Statement-Prospectus by reference and
the unaudited pro forma consolidated financial information set forth in this
Joint Proxy Statement-Prospectus.
 
  The selected unaudited pro forma consolidated financial information at June
30, 1997 set forth below was prepared as if the Merger and the Lucent
Acquisition had been consummated on June 30, 1997. The selected unaudited pro
forma consolidated financial information for the year ended March 31, 1997 and
three months ended June 30, 1997 set forth below was prepared as if the Merger
and the Lucent Acquisition had been consummated on April 1, 1996.
 
  The unaudited pro forma financial information set forth in this Joint Proxy
Statement-Prospectus has been prepared assuming the Merger and the Lucent
Acquisition are accounted for using the purchase method of accounting.
Accordingly, the unaudited pro forma consolidated financial information assumes
that (1) the Merger consideration consisting of (i) the fair value of
securities to be issued by Elcotel to effect the Merger, (ii) the fair value of
outstanding common stock, options and warrants of TSG to be converted into
Elcotel securities, and (iii) the estimated direct costs and expenses to be
incurred by Elcotel in connection with the transaction, is allocated to the
assets and liabilities of TSG based on their estimated fair values and (2) the
aggregate purchase price related to the Lucent Acquisition is allocated to the
assets acquired based on their estimated fair values.
 
  The selected unaudited pro forma consolidated financial information presented
below reflects pro forma adjustments that are directly attributable to the
Merger and the Lucent Acquisition and the use of the purchase method of
accounting. The selected unaudited pro forma consolidated operations data does
not reflect anticipated cost reductions or revenue enhancements expected to be
realized from the Merger or the anticipated revenues, gross profit and
operating expenses from the Lucent Acquisition. Accordingly, the unaudited pro
forma consolidated operations data for the year ended March 31, 1997 and three
months ended June 30, 1997 are not necessarily indicative of the consolidated
results of operations as they might have been had the Merger and Lucent
Acquisition actually occurred on the dates indicated, nor are they necessarily
indicative of future results.

                             CERTAIN RISK FACTORS
 
  Holders of TSG Common Stock, in evaluating whether to approve the Merger and
thereby become holders of Elcotel Common Stock, and holders of Elcotel Common
Stock, in evaluating whether to approve the issuance of Elcotel Common Stock
in connection with the Merger, should carefully consider the following risk
factors, in addition to the other information included and incorporated by
reference in this Joint Proxy Statement--Prospectus.
 
INTEGRATION OF OPERATIONS
 
  The integration of operations following the Merger and the Lucent
Acquisition will require the dedication of management resources which will
detract from attention to the day-to-day business of Elcotel subsequent to the
Merger. The difficulties of integration are increased by the necessity of
coordinating geographically separated organizations, integrating personnel
with disparate business backgrounds, and combining two different corporate
cultures. Following the Merger, Elcotel is expected to seek to reduce expenses
by eliminating duplicative or unnecessary facilities, employees, research and
development programs and other expenses in the areas of sales, marketing,
advertising and administration. Elcotel will utilize existing systems which it
believes have been effective in controlling costs and improving margins to
achieve improved operating efficiencies in TSG's manufacturing and inventory
management. Additionally, Elcotel will seek to combine sales and marketing
channels, promotional activities, and product marketing strategies. There can
be no assurance that Elcotel will be able subsequent to the Merger to reduce
expenses in this fashion, that there will not be high costs associated with
such activities, and that there will not be other material adverse effects of
such activities. In particular, the realization of cost savings will depend
upon an effective and expedient transition schedule which may span a period of
six months to one year. The near-term effect could be a reduction in net
income for the year subsequent to the Merger and short-term dilution.
 
FIXED EXCHANGE RATIO DESPITE POSSIBLE CHANGE IN STOCK PRICES
 
  The Exchange Ratio is expressed in the Merger Agreement as a fixed ratio.
Accordingly, the Exchange Ratio will not be adjusted in the event of any
increase or decrease in the market price of either Elcotel Common Stock or TSG
Common Stock. Additionally, neither Elcotel nor TSG has the right to terminate
the Merger Agreement in the event of any increase or decrease in the market
price of either Elcotel Common Stock or TSG Common Stock. The market price of
Elcotel Common Stock at the Effective Time may vary from its price at the date
of this Joint Proxy Statement--Prospectus and the dates of the Elcotel Annual
Meeting and TSG Special Meeting, possibly by a material amount. Such
variations may be the result of changes in the business, operations or
prospects of Elcotel or TSG, market assessments of the likelihood that the
Merger will be consummated and the timing thereof, regulatory considerations,
general market and economic conditions and other factors, many of which will
be beyond the control of Elcotel or TSG. Because the Effective Time may occur
at a date later than the date of the Elcotel Annual Meeting and the TSG
Special Meeting, there can be no assurance that the market price of Elcotel
Common Stock on such date will be indicative of its market price at the
Effective Time. Elcotel and TSG have no intention of resoliciting stockholder
approval should the market prices of Elcotel Common Stock or TSG Common Stock
change materially after the date of the Elcotel Annual Meeting or the TSG
Special Meeting, as the case may be. The Effective Time will occur no later
than the fifth business day after satisfaction or waiver of the conditions to
the consummation of the Merger set forth in the Merger Agreement, unless
another date is agreed to in writing. Because the Exchange Ratio will not be
adjusted to reflect changes in the market value of Elcotel Common Stock or TSG
Common Stock, the market value of the Elcotel Common Stock issued in the
Merger, and the value of the TSG Common Stock surrendered in the Merger, may
be higher or lower than the value of such shares at the time the Merger was
negotiated or approved by stockholders. Stockholders of Elcotel and TSG are
urged to obtain current market quotations for Elcotel Common Stock and TSG
Common Stock. See "Summary--Comparative Market Prices."
 
                                      15
<PAGE>
 
DEPENDENCE ON KEY PERSONNEL
 
  Following the Merger, Elcotel's business will be dependent upon the
performance of certain key individuals, including C. Shelton James, its
Chairman of the Board, Tracey Gray, its President and Chief Executive Officer,
and Vincent Bisceglia, its Chief Operating Officer. The loss of services of
any of these persons could have a material adverse effect on Elcotel. In
connection with the Merger, Elcotel will enter into employment agreements with
each of Messrs. James, Gray and Bisceglia, but these agreements do not ensure
that Messrs. James, Gray and Bisceglia will remain employed by Elcotel. See
"The Merger--Interests of Certain Persons and Employee Matters--Employment
Agreements."
 
INTENSE COMPETITION
 
  The public communications industry is highly competitive. Prior to 1984, the
telcos held a monopoly in the pay telephone industry, and they continue to
have a dominant share of the public communications market. Elcotel competes
with firms in the United States (principally Intellicall, Protel, Quadrum and,
prior to the Merger, TSG) that manufacture and market to telcos and
independent payphone operators privately-owned payphones and other products
similar to Elcotel's products. In addition, there are many other firms which
have the resources and ability to develop and market products which could
compete with Elcotel's products. Elcotel expects possible competition from
other companies. Some telecommunications companies, already established in the
telephone industry with substantial engineering, manufacturing and capital
resources, are positioned to enter the public communications market, some of
which are foreign manufacturers. Telcos also compete with private payphone
operators by making site owner compensation arrangements more attractive for
their existing phones, thereby reducing the site owners' incentive to use
privately owned payphones. Many existing and potential competitors have
financial, marketing, management and technical resources substantially greater
than those of Elcotel. As a result, they may be able to respond more quickly
to new or emerging technologies and changes in customer requirements, or to
devote greater resources to the development, promotion and sale of their
products than Elcotel. It is also possible that new competitors may emerge and
acquire significant market share. Possible new competitors include large
foreign corporations, RBOCs and other entities with substantial resources.
Increased competition is likely to result in price reductions, reduced gross
margins and loss of market share, any of which would have a material adverse
effect on Elcotel's business, results of operations and financial condition.
There can be no assurance that Elcotel will be able to compete successfully
against current or future competitors or that competitive pressures will not
have a material adverse effect on Elcotel's business, results of operations
and financial condition. The market for international public communications is
highly competitive, and numerous competitors are larger, better capitalized
and have greater experience in marketing their products internationally. See
"Technology Service Group, Inc.--Competition; Sales and Markets."
 
  Telecommunications technology is constantly changing. Alternative means of
communicating, such as radio-based paging services, cellular mobile telephone
services and personal communication services, are becoming more popular. To
date, such alternative means of communicating have not reduced the need for or
replaced payphones. As competing technologies are developed, however, or
become substantially less expensive, there is some risk that public payphones
will become less widely used. In such event, the demand for payphone products
and services could be materially and adversely affected. Elcotel expects
competition from such competing technologies. In addition, even if payphones
continue to exist or proliferate world-wide, technological advances could
occur that would render Elcotel's technology and know-how non-competitive.
Such development would have a material adverse effect on Elcotel. See
"Technology Service Group, Inc.--Competition."
 
RISKS ASSOCIATED WITH INTERNATIONAL MARKET
 
  Elcotel's export sales to international markets approximated $1,920,000,
$1,536,000, and $8,045,000 during fiscal 1995, 1996 and 1997, respectively.
Conducting business internationally is subject to a number of potential risks,
including political instability, foreign currency fluctuations, adverse
movements in exchange rates, economic instability, the imposition of tariffs
and import and export controls, changes in governmental policies (including
U.S. policy toward foreign countries), general credit and business risks and
other factors, one or more
 
                                      16
<PAGE>
 
of which, if they occur, could have an adverse effect on Elcotel's ability to
generate international sales or operations. Elcotel's sales to date have been
denominated in U.S. dollars and as a result, no losses related to currency
fluctuations have been incurred. For the same reason, Elcotel has not engaged
in currency hedging activities. There is no assurance, however, that Elcotel
will be able to continue to export its products in U.S. dollar denominations
or that its business will not become subject to significant exposure to
foreign currency risks. Finally, many of Elcotel's known and potential
international competitors have substantially more financial and other
resources than Elcotel and, therefore, are formidable competitors. See
"Technology Service Group, Inc.--Competition; Sales and Markets."
 
TECHNOLOGICAL OBSOLESCENCE
 
  Because of rapid technological changes in the telecommunications industry,
there can be no assurance that Elcotel's payphones will not be rendered
obsolete or unmarketable in the future due to the introduction of new products
or technological developments by other companies. Elcotel believes that it
will be required to develop enhancements, new products and services in the
future to remain competitive. See "Technology Service Group, Inc.--The Public
Payphone Industry."
 
GOVERNMENT REGULATION; POSSIBLE ADVERSE EFFECT OF FUTURE REGULATORY CHANGES
 
  Products and services offered by Elcotel and operated by its customers are
subject to varying degrees of regulation at both the federal and state levels.
There can be no assurance that changes in such regulation, if proposed and
adopted, would not have an adverse impact on the operations of Elcotel and its
customers. The privately owned pay telephone industry is highly regulated by
the Federal Communications Commission (the "FCC") and the various state public
utilities commissions. Certain of Elcotel's products must comply with FCC
rules. Parts 15 and 68 establish technical standards and procedural and
labeling requirements for equipment subject to those rules. While Elcotel
believes that its products currently comply with the technical requirements of
the FCC and the states, there can be no assurance that additional or different
technical requirements will not be adopted which would require Elcotel to
modify its telephones or that rate or other regulatory changes will not be
adopted which might adversely affect Elcotel's operations or its customers.
See "Technology Service Group, Inc.--Government Regulation."
 
  The Telecommunications Reform Act of 1996 requires that the FCC establish a
per call compensation plan to ensure that all payphone service providers are
fairly compensated for every completed intrastate and interstate call using
their payphones. In September 1996, the FCC established an interim
compensation plan for payphone service providers for access code and
subscriber 800 calls. Under that interim compensation plan, payphone service
providers were compensated at a flat rate of $45.85 per payphone per month
(compared to the previous compensation of $6.00 per month) until September 1,
1997 and thereafter at the rate of $.35 per 800 or access code call. The
United States Court of Appeals for the District of Columbia Circuit has
vacated the FCC's action in adopting the interim compensation plan and
remanded to the FCC for further consideration the issue of compensation for
such calls on a permanent and interim basis. On October 9, 1997 the FCC issued
an order addressing certain issues with respect to payphone compensation
previously remanded to it by the Court of Appeals. The FCC set the per call
compensation rate at $.284 per call during the period October 7, 1997 through
October 6, 1999. After that period, the compensation rate would be whatever is
charged at the phone for a local call, less $.066, the amount the FCC
determined to be the avoided cost in completing a non-coin call. The FCC must
still determine the compensation rate for the period November 6, 1996 through
October 6, 1997 and which carriers must pay compensation for that period. It
is likely that the FCC's latest action may also be challenged in court. The
ultimate outcome with respect to per call compensation will have a significant
impact on the business and operations of Elcotel's customers. Elimination or
significant reductions in the amount, or delays in the payment, of per call
compensation may reduce demand for payphones and the ability of Elcotel to
collect its receivables from its customers. See "Technology Service Group,
Inc.--Government Regulation."
 
  The Telecommunications Act of 1996 also deregulated many elements of the
telecommunications industry as a means of stimulating competition. This
deregulation could affect the payphone products industry. Although
 
                                      17
<PAGE>
 
Elcotel believes that deregulation generally will benefit it, there can be no
assurance that Elcotel will benefit from deregulation or that it will not be
adversely affected by deregulation. Elcotel will monitor future changes in
federal and state regulations and may be required to modify its products to
comply with additional technical requirements or other factors which could
result in Elcotel's products not being in compliance with federal or state
regulations.
 
DIVIDENDS NOT LIKELY
 
  Elcotel does not anticipate paying any cash dividends to its stockholders in
the foreseeable future. Elcotel's current borrowing arrangement with its bank
prohibits Elcotel from paying cash dividends without the bank's consent. It is
likely that any new borrowing arrangements entered into in connection with the
Merger will have a similar prohibition. See "The Merger--Refinancing of TSG
and Elcotel Indebtedness."
 
CONTROL OF ELCOTEL
 
  Upon consummation of the Merger, Wexford and Fundamental will beneficially
own in the aggregate approximately 30% of the outstanding Elcotel Common
Stock. Pursuant to the Stockholders' Agreement to be entered into among
Elcotel, Fundamental and Wexford (the "Fundamental/Wexford Stockholders'
Agreement") on the Closing Date, Wexford and Fundamental have agreed to vote,
during the period ending immediately after the second annual meeting of
Elcotel stockholders which occurs after the Annual Meeting, all of their
shares of Elcotel Common Stock in favor of any nominees for director of
Elcotel nominated by the incumbent Elcotel Board. Fundamental and Wexford will
have substantial influence over all matters requiring approval of the
stockholders of Elcotel. The combined voting power of Fundamental and Wexford
may have the effect of discouraging certain types of transactions involving an
actual or potential change in control of Elcotel where such change in control
is not in the interest of at least one of Fundamental or Wexford.
 
DILUTION TO ELCOTEL STOCKHOLDERS
 
  The owners of the outstanding Elcotel Common Stock immediately prior to the
Merger will own approximately 62%, and the former TSG stockholders will own
approximately 38%, of the Elcotel Common Stock outstanding immediately after
the consummation of the Merger.
 
DEBT REFINANCING
 
  In connection with the consummation of the Merger, Elcotel intends to
refinance the existing indebtedness of TSG to its bank and of Elcotel to its
bank. Elcotel intends to seek a revolving line of credit of approximately $15
million for such refinancing. There can be no assurance that Elcotel will be
able to obtain such a line of credit or as to the terms of such line of
credit. See "The Merger--Refinancing of TSG and Elcotel Indebtedness."
 
LIMITED NUMBER OF CUSTOMERS IN CERTAIN MARKETS
 
  TSG derives substantially all of its revenues from certain of the RBOCs. The
loss of any one of such RBOC customers or a significant reduction in sales to
such RBOCs would have a material adverse effect on TSG's business and, after
the Merger, Elcotel's business. TSG's ability to maintain and increase its
sales is dependent on its ability to compete for and maintain satisfactory
relationships with the RBOCs, particularly TSG's current significant
customers. Elcotel will be subject to this risk, although it will be lessened
somewhat because the amount of sales to this limited number of customers will
represent a smaller percentage of the total sales of Elcotel after the Merger
than such amount represented as a percentage of TSG's total sales. See
"Technology Service Group, Inc.--Sales and Markets."
 
  Pursuant to the Telecommunications Act of 1996, the RBOCs will be permitted
to manufacture and provide telecommunications equipment and to manufacture
customer premises equipment when certain competitive conditions have been met.
It is possible that one or more RBOCs will decide to manufacture payphone
products, which could cause Elcotel to compete with such RBOCs for customers.
The existence of such a competitive relationship would decrease demand for
Elcotel's products by such RBOCs. See "Technology Service Group, Inc.--
Government Regulation."
 
                                      18
<PAGE>
 
DEPENDENCE ON CERTAIN MANUFACTURERS; SINGLE SOURCES OF SUPPLY
 
  Elcotel generally assembles its smart payphone products from assemblies
produced by certain manufacturers under contractual arrangements. To the
extent that such manufacturers encounter difficulties in their production
processes that delay shipment to Elcotel or that affect the quality of items
supplied to Elcotel, Elcotel's ability to satisfy its sales obligations or
otherwise to meet supply schedules with its customers can be adversely
affected. In the event that contract manufacturers delay shipments or supply
defective materials to Elcotel, and such delays or defects are material,
Elcotel's customer relations could deteriorate and its sales and operating
results could be materially and adversely affected.
 
  After the Merger, many of Elcotel's products in terms of revenues will
contain components or assemblies that are purchased from single sources.
Elcotel believes that there are alternative sources of supply for most of the
components and assemblies currently purchased from single sources. Some of the
components and assemblies used by Elcotel for which there are not immediately
available alternative sources of supply are provided to Elcotel under standard
purchase arrangements. If a shortage or termination of the supply of any one
or more of such components or assemblies were to occur, however, Elcotel's
business could be materially and adversely affected. In such event, Elcotel
would have to incur the costs associated with redesigning its products to
include available components or assemblies or otherwise obtain adequate
substitutes, which costs could be material. Also, any delays with respect to
redesigning products or obtaining substitute components would materially
adversely affect Elcotel's business. See "Technology Service Group, Inc.--
Manufacturing, Assembly and Sources of Supply."
 
FIXED PRICE PRODUCTS
 
  TSG's agreements with its manufacturers generally provide that TSG will bear
certain cost increases incurred by the manufacturer. Accordingly, TSG's
manufacturing costs may fluctuate based on costs incurred by its contract
manufacturers and such fluctuations could have a material and adverse impact
on Elcotel's earnings after the Merger. TSG's sales agreements with customers
generally have fixed product prices with limited price escalation provisions.
Consequently, there is a risk that after the Merger Elcotel may not be able to
pass on price increases to those customers. In the event Elcotel's costs
increase or orders are lost due to price increases, Elcotel's profitability
would be adversely affected. See "Technology Service Group, Inc.--Sales and
Markets."
 
PATENTS AND TECHNOLOGY
 
  After the Merger, Elcotel will own several patents covering aspects of its
payphone products. As a result of the Lucent Acquisition, Elcotel is licensed
under several patents covering aspects of the payphone products acquired from
Lucent. However, Elcotel views its business as not being primarily dependent
upon patent protection. Elcotel does not believe that it is infringing on the
patents of others. There can be no assurance, however, that infringement
claims will not be asserted in the future or that the results of any patent
related litigation would not be material to Elcotel. TSG has a license
agreement under which certain minimum annual royalties must be paid to the
licensor in the event that a patent for the licensed algorithm is issued. TSG
management does not believe that a patent for the algorithm will be issued due
to existing prior art, but TSG cannot assure that such patent will not be
issued. If a patent were to be issued, significant royalties would be payable
regardless of whether or not the algorithm is incorporated into TSG's
products. See "Technology Service Group, Inc.--Licenses, Patents and
Trademarks" and "Consolidated Financial Statements of "Technology Service
Group, Inc." in Appendix C.
 
POTENTIAL ENVIRONMENTAL LIABILITIES
 
  During the year ended March 28, 1997, TSG completed the evaluation,
assessment and monitoring of soil and groundwater contamination at one of
TSG's former facilities in Florida in accordance with requirements stipulated
by the Florida Department of Environmental Protection (the "FDEP"), and in
April 1997 received a formal "no further action status" notification for the
site from the FDEP. Accordingly, TSG has not accrued any additional costs with
respect to this site. It is possible, however, that the FDEP could reopen the
investigation
 
                                      19
<PAGE>
 
in the future and require TSG to take further actions at the site. TSG cannot
estimate a range of costs, if any, that it could incur in the future since
such costs would be dependent upon the scope of additional actions, if any,
that may be required by the State of Florida.
 
  During the year ended March 28, 1997, TSG was a Potentially Responsible
Party ("PRP") for undertaking response actions at a facility for the
treatment, storage, and disposal of hazardous substances operated by Seaboard
Chemical Corporation from 1975 to 1989 at Jamestown, North Carolina. However,
TSG, as a small generator "De Minimis" party, executed a buy-out agreement
with respect to the remediation activities at a cost of approximately $8,200
during the year ended March 28, 1997. TSG believes, based on information
presently available to TSG, that it has no further obligations with respect to
the site. However, if additional waste is attributed to TSG, it is possible
that TSG could be liable for additional costs. TSG cannot estimate a range of
costs, if any, that it could incur in the future since such costs would be
dependent upon the amount of additional waste, if any, that could be
attributed to TSG.
 
  TSG has also been notified that it is a PRP with respect to response actions
at the Galaxy/Spectron Superfund Site in Elkton, Maryland. TSG, however, is
also a De Minimis party with respect to this site, and TSG believes its
proportionate share of costs to undertake response actions will likely be
insignificant. TSG has received notification that the De Minimis parties will
be able to buy out and obtain a release from any further clean-up liability at
the site at a cost presently estimated at $3.70 per gallon of contributed
waste, which would amount to $2,849 with respect to TSG's contribution. TSG
has not incurred any costs with respect to this site and believes that its
ultimate costs will not be material.
 
  These potential environmental liabilities could have an adverse effect on
Elcotel after the Merger. See "Technology Service Group, Inc.--Potential
Environmental Liabilities."

 Board of Directors' Recommendations
 
  THE ELCOTEL BOARD BY A VOTE OF 5 TO 2 HAS APPROVED THE MERGER AGREEMENT AND
RECOMMENDS THAT ELCOTEL STOCKHOLDERS VOTE "FOR" THE APPROVAL OF THE ISSUANCE
OF ELCOTEL COMMON STOCK PURSUANT TO THE MERGER AGREEMENT AND ANY OTHER ACTIONS
REQUIRED IN FURTHERANCE OF THE MERGER. SEE "THE MERGER--ELCOTEL'S REASONS FOR
THE MERGER; RECOMMENDATION OF THE ELCOTEL BOARD." THE ELCOTEL BOARD
UNANIMOUSLY RECOMMENDS THAT ELCOTEL STOCKHOLDERS VOTE "FOR" (I) THE ELECTION
OF THE DIRECTOR NOMINEES SPECIFIED HEREIN, (II) THE APPROVAL OF THE ELCOTEL
AMENDMENT, (III) THE RATIFICATION OF THE APPOINTMENT OF DELOITTE & TOUCHE LLP
AS ELCOTEL'S INDEPENDENT PUBLIC ACCOUNTANTS FOR THE FISCAL YEAR ENDING MARCH
31, 1998, (IV) THE APPROVAL OF THE AMENDMENT TO THE 1991 STOCK OPTION PLAN AND
(V) THE APPROVAL OF THE AMENDMENTS TO THE DIRECTORS STOCK OPTION PLAN. SEE
"THE MERGER--ELCOTEL'S REASONS FOR THE MERGER; RECOMMENDATION OF THE ELCOTEL
BOARD."
 
 Record Date; Required Vote; Quorum.
 
  Only holders of record of Elcotel Common Stock at the close of business on
the Elcotel Record Date (which is October 22, 1997) are entitled to receive
notice of and to vote at the Elcotel Annual Meeting. At the close of business
on the Elcotel Record Date, there were 8,210,352 shares of Elcotel Common
Stock outstanding. Each share of Elcotel Common Stock is entitled to one vote
on all matters presented to the Elcotel Annual Meeting with no right to vote
cumulatively.
 
  Elcotel's Bylaws provide that the presence, in person or by proxy, of a
majority of the issued and outstanding shares of Elcotel Common Stock entitled
to vote at the Elcotel Annual Meeting will constitute a quorum. A quorum, once
established, will not be broken by the withdrawal from the Elcotel Annual
Meeting of enough votes to leave less than a quorum, and the votes present at
the Elcotel Annual Meeting after the establishment of a quorum will be
sufficient to transact all business at the Elcotel Annual Meeting. Shares
represented by proxies that reflect abstentions or "broker non-votes" (i.e.,
shares held by a broker or nominee which are represented at the meeting, but
with respect to which such broker or nominee is not empowered to vote on a
particular proposal) will be counted as shares that are present and entitled
to vote for purposes of determining the presence of a quorum.
 
  In the event that a quorum is not present at the Elcotel Annual Meeting, it
is expected that the Elcotel Annual Meeting will be adjourned or postponed to
solicit additional proxies, except that shares represented by proxies which
have been voted "against," or have abstained with respect to the proposal to
approve the issuance of shares of Elcotel Common Stock pursuant to the Merger
Agreement and any other actions required in furtherance of the Merger, will
not be used to vote "for" postponement or adjournment of the Elcotel Annual
Meeting for the purpose of allowing additional time for soliciting additional
votes "for" such adoption.
 
                                      21
<PAGE>
 
  Approval of the amendment to the Certificate of Incorporation of Elcotel to
increase the number of shares of Elcotel Common Stock authorized for issuance
to 30,000,000 will require the affirmative vote of a majority of the shares of
Elcotel Common Stock outstanding as of the Elcotel Record Date. Approval of
the issuance of Elcotel Common Stock pursuant to the Merger Agreement (as
required by rules applicable to companies whose securities are traded on the
Nasdaq National Market), ratification of the appointment of Deloitte & Touche
llp as the independent public accountants of Elcotel for the fiscal year
ending March 31, 1998 and the approval of the amendments to the 1991 Stock
Option Plan and the Directors Stock Option Plan will require the affirmative
vote of a majority of the shares of Elcotel Common Stock present in person or
represented by properly executed proxy at the Elcotel Annual Meeting. The
election of each director will require the affirmative vote of a plurality of
the shares of Elcotel Common Stock present in person or represented by
properly executed proxy at the Elcotel Annual Meeting. Abstentions will be
counted for purposes of determining the total number of votes cast with
respect to a particular matter. Broker non-votes will not be counted for
purposes of determining the number of votes cast with respect to the
particular proposal on which the broker has expressly not voted. Broker non-
votes with respect to Elcotel proposals set forth in this Joint Proxy
Statement-Prospectus will therefore not be considered votes cast and,
accordingly, will not affect the determination as to whether a majority of
votes cast has been obtained with respect to a particular matter, other than
with respect to the approval of the Elcotel Amendment which requires the
affirmative vote of a majority of the outstanding shares of Elcotel Common
Stock.
 
 Share Ownership of Officers, Directors and Certain Stockholders
 
  At the close of business on the Elcotel Record Date, directors and executive
officers of Elcotel and their respective affiliates were the beneficial owners
of an aggregate of approximately 2,308,961 shares (approximately 27.5%) of the
Elcotel Common Stock then outstanding (which amount includes the shares owned
by Fundamental referred to in the next sentence). As of the Elcotel Record
Date, Fundamental owned an aggregate of 1,439,223 shares (approximately 17.5%)
of the Elcotel Common Stock then outstanding. See "Other Information Regarding
Elcotel--Security Ownership of Certain Beneficial Owners and Management."
Pursuant to a Voting Agreement, dated as of August 13, 1997, among Elcotel,
Wexford, Fundamental, Vincent Bisceglia and C. Shelton James ("Voting
Agreement"), Fundamental has agreed to vote its shares of Elcotel Common Stock
in favor of the issuance of Elcotel Common Stock in connection with the Merger
and has generally agreed not to transfer such shares before the consummation
of the Merger or termination of the Merger Agreement. Such agreement increases
the likelihood that the vote of the Elcotel stockholders required for the
issuance of Elcotel Common Stock in connection with the Merger will be
obtained. See "The Voting Agreement."
 
TSG SPECIAL MEETING
 
 General; Matters to be Considered
 
  The TSG Special Meeting will be held at Deloitte & Touche llp, 125 Summer
Street, Boston, MA 02110 on Friday, December 5, 1997, at 10:00 A.M., local
time. The purpose of the TSG Special Meeting is to consider and vote upon the
following matters: (i) the approval of the Merger Agreement and any other
actions as may be required in furtherance of the Merger; and (ii) the
transaction of such other business as may properly come before the TSG Special
Meeting and any adjournment or postponement thereof, and matters incident to
the conduct of the TSG Special Meeting.
 
 Revocability of Proxies; Default Voting of Proxies
 
  Any person giving a proxy has the power to revoke it at any time before its
exercise by a later dated proxy, a written revocation sent to the Secretary of
TSG, or attendance at the TSG Special Meeting and voting in person. In the
absence of contrary instructions, properly executed proxies, received and
unrevoked, will be voted by the persons named in the proxy: (i) for the
approval of the Merger Agreement and any other actions as may be required in
furtherance of the Merger; and (ii) in their discretion, on such other
business as may properly come before the TSG Special Meeting and matters
incident to the conduct of the TSG Special Meeting.

 Board of Directors' Recommendations
 
  THE TSG BOARD HAS UNANIMOUSLY APPROVED THE MERGER AGREEMENT AND UNANIMOUSLY
RECOMMENDS THAT TSG STOCKHOLDERS VOTE "FOR" THE APPROVAL OF THE MERGER
AGREEMENT AND ANY OTHER ACTIONS AS MAY BE REQUIRED IN FURTHERANCE OF THE
MERGER. SEE "THE MERGER--TSG'S REASONS FOR THE MERGER; RECOMMENDATION OF THE
TSG BOARD."
 
 Record Date; Required Vote; Quorum.
 
  Only holders of record of TSG Common Stock at the close of business on the
TSG Record Date (which is October 22, 1997) are entitled to receive notice of
and to vote at the TSG Special Meeting. At the close of business on the TSG
Record Date, there were 4,708,851 shares of TSG Common Stock outstanding. Each
share of TSG Common Stock is entitled to one vote on all matters presented to
the TSG Special Meeting with no right to vote cumulatively.
 
  TSG's Bylaws provide that the presence, in person or by proxy, of a majority
of the issued and outstanding shares of TSG Common Stock entitled to vote at
the TSG Special Meeting will constitute a quorum. A quorum, once established,
will not be broken by the withdrawal from the TSG Special Meeting of enough
votes to leave less than a quorum, and the votes present at the TSG Special
Meeting after the establishment of a quorum will be sufficient to transact all
business at the TSG Special Meeting. Shares represented by proxies that
reflect abstentions or "broker non-votes" (i.e., shares held by a broker or
nominee which are represented at the meeting, but with respect to which such
broker or nominee is not empowered to vote on a particular proposal) will be
counted as shares that are present and entitled to vote for purposes of
determining the presence of a quorum.
 
  Approval of the Merger Agreement will require the affirmative vote of a
majority of the shares of TSG Common Stock outstanding as of the TSG Record
Date. Because Wexford (which owns approximately 52% of the shares of TSG
Common Stock outstanding and has generally agreed not to transfer those shares
before the consummation of the Merger or termination of the Merger Agreement)
has agreed to vote those shares in favor of the approval of the Merger
Agreement, such agreement ensures that the vote of TSG stockholders required
to approve the Merger Agreement will be obtained. See "The Voting Agreement."
Abstentions will be counted for purposes of determining the total number of
votes cast with respect to a particular matter. Broker non-votes will not be
counted for purposes of determining the number of votes cast with respect to
the particular proposal on which the broker has expressly not voted. Broker
non-votes with respect to TSG proposals set forth in this Joint Proxy
Statement-Prospectus will therefore not be considered votes cast. Accordingly,
broker non-votes will affect the determination as to whether a majority of
votes cast has been obtained with respect to the approval of the Merger
Agreement, which approval will require the affirmative vote of a majority of
the outstanding shares of TSG Common Stock, but may not affect the
determination as to whether a majority of votes has been obtained with respect
to any other matters as may be voted upon. However, as indicated above,
approval of the Merger Agreement by the stockholders of TSG is ensured because
Wexford has agreed to vote its shares in favor of the approval of the Merger
Agreement.
 
 Share Ownership of Officers, Directors and Certain Stockholders
 
  At the close of business on the TSG Record Date, directors and executive
officers of TSG and their affiliates were the beneficial owners of an
aggregate of approximately 3,276,854 shares (approximately 65%) of the TSG
Common Stock then outstanding (which amount includes the shares owned by
Wexford referred to in the next sentence). As of the TSG Record Date, Wexford
owned an aggregate of 2,444,286 shares (approximately 52%) of the TSG Common
Stock then outstanding. See "Directors and Executive Officers of TSG--Security
Ownership of Certain Beneficial Holders and Management." Wexford has agreed to
vote its shares of TSG Common Stock in favor of the approval of the Merger
Agreement and has generally agreed not to transfer such shares before the
consummation of the Merger or termination of the Merger Agreement. Such
agreement ensures that the vote of TSG stockholders required to consummate the
Merger will be obtained. See "The Voting Agreement."

                                  THE MERGER
 
GENERAL
 
  The description of the Merger and the Merger Agreement contained in this
Joint Proxy Statement-Prospectus does not purport to be complete and is
qualified in its entirety by reference to the Merger Agreement, a copy of
which is attached hereto as Appendix A and incorporated herein by reference.
 
  At the Effective Time, Merger Subsidiary will merge with and into TSG,
leaving TSG as the surviving corporation in the Merger and a wholly-owned
subsidiary of Elcotel. The Merger will become effective at such time as the
certificate of merger is filed with the Delaware Secretary of State, or at
such later time as is agreed by Elcotel and TSG and specified in the
certificate of merger. The filing of the certificate of merger will occur no
later than the fifth business day after satisfaction or waiver of the
conditions precedent to the consummation of the Merger (see "The Merger
Agreement--General Conditions Precedent to the Merger") unless another date is
agreed to in writing by Elcotel, TSG and Merger Subsidiary.
 
  At the Effective Time, each share of TSG Common Stock issued and outstanding
immediately prior to the Effective Time (other than shares of TSG Common Stock
owned by TSG as treasury stock and shares of TSG Common Stock owned by Elcotel
or any subsidiary of Elcotel or TSG), will automatically be converted into the
right to receive 1.05 fully paid and nonassessable shares of Elcotel Common
Stock. Holders of TSG Stock Options will receive options and rights to
purchase, at a proportionately reduced per share exercise price, a number of
shares of Elcotel Common Stock equal to 1.05 times the number of shares of TSG
Common Stock they were entitled to purchase immediately prior to the Effective
Time under such TSG Stock Options. Holders of TSG Warrants will receive
warrants to purchase, at a proportionately reduced per share exercise price, a
number of shares of Elcotel Common Stock equal to 1.05 times the number of
shares of TSG Common Stock they were entitled to purchase immediately prior to
the Effective Time under such TSG Warrants.
 
BACKGROUND OF THE MERGER
 
  In the third calendar quarter of 1994, Elcotel and TSG had preliminary
discussions with respect to a possible purchase of TSG by Elcotel. Elcotel
made two offers to purchase TSG for combinations of cash and Elcotel Common
Stock. TSG rejected both offers in favor of Wexford's offer to purchase TSG
for cash only. For a description of the acquisition of TSG by Wexford, see
"Technology Service Group, Inc.--History."
 
  On January 30, 1997, Rodney O'Connor and Robert L. Reisley of Cameron
Associates, a financial adviser to Elcotel, met with C. Shelton James, Chief
Executive Officer and Chairman of the Board of Elcotel, and Tracey Gray,
President of Elcotel, at Elcotel's headquarters to discuss strategic
alternatives to maximize shareholder value, including the sale of Elcotel to a
third party, a merger and/or the acquisition of one or more companies
operating in the public communications equipment industry. TSG was identified
as an attractive acquisition target because the two companies complement one
another in terms of their respective customer bases, product lines and market
focus. Several other benefits were also identified including the potential for
gross margin
 
                                      24

improvement and consolidation savings, greater industry visibility, synergies
in marketing, and, if the transaction were structured as a merger, greater
liquidity for investors due to an increase in the public float of the combined
company's stock.
 
  In early February 1997, Vincent Bisceglia, the President and Chief Executive
Officer of TSG, received a telephone call from Mr. Gray regarding Elcotel's
interest in exploring a possible combination of TSG and Elcotel. Mr. Bisceglia
was receptive to the concept. Pursuant to authorization from Mr. James, Mr.
Reisley contacted TSG's Chairman of the Board, David Steadman, to discuss the
potential benefits of merging the two companies. Mr. Steadman indicated that
he understood the rationale for the combination and recommended that, in view
of the size of Wexford's holding of TSG stock, Mr. Reisley contact Robert M.
Davies, Executive Vice President of Wexford Management. Mr. Bisceglia had a
further discussion with Mr. Gray on February 19, 1997 concerning the structure
of a merger and the advantages and problems that might be encountered in a
combination of the two companies.
 
  On February 21, 1997, Messrs. Reisley and O'Connor of Cameron Associates and
Messrs. Davies and Mark L. Plaumann of Wexford Management met in the offices
of Wexford Management. Mr. Reisley and Mr. O'Connor reviewed the merits of
combining Elcotel and TSG and proposed merging the two companies in a cashless
transaction, in which TSG stockholders would receive shares of Elcotel Common
Stock. Mr. Davies indicated that he held similar views regarding consolidation
opportunities and as the investment manager of the majority stockholder of
TSG, Wexford Management would consider such a transaction based on an
appropriate valuation of TSG and adequate representation on the combined
company's board of directors. The parties agreed to exchange certain financial
information and to instruct Mr. Gray and Mr. Bisceglia to begin discussions
regarding the management and organizational structure of a combined company.
On February 27, 1997, TSG and Elcotel executed a confidentiality agreement
with respect to information to be exchanged by the two companies.
 
  During the first two weeks of March 1997, the parties exchanged financial
information and began preliminary negotiations on a transaction structure.
Messrs. Gray and Bisceglia also met several times to discuss the
organizational structure and customer-related issues involved in a combination
of the two companies.
 
  On March 14, 1997, the TSG Board held a meeting at which Mr. Bisceglia
reported on the meetings that had taken place between Wexford Management, on
behalf of Wexford, and Cameron Associates. Mr. Bisceglia noted that over the
prior eighteen months he had had discussions with five different companies in
the payphone industry about possible acquisitions, none of which proceeded
beyond the preliminary discussion stage. He also reminded directors that TSG
had had discussions with Elcotel in 1994 when TSG was in the beginning stages
of its restructuring. The TSG Board then discussed the fact that TSG and
Elcotel could complement each other as to products, customers and technology
since Elcotel sells mainly to the private payphone market, while TSG's main
customers are the RBOCs. Mr. Plaumann, a director of TSG and an officer of
Wexford Management, presented to the TSG Board an analysis showing that there
could be both margin and consolidation savings in a merger of the two
companies and that the resulting entity would be approximately twice the
current size of TSG. Directors discussed TSG's options for going forward and
concluded by giving management authorization to continue discussions with
Elcotel.
 
  On March 20, 1997, Mr. Bisceglia had a further discussion with Mr. Gray
about the composition of the board of directors, key management positions and
employment agreements for certain employees of the combined entity. On April
7, 1997, representatives of TSG, Wexford Management, Fundamental and Elcotel
met in New York City in an attempt to establish a basis for continuing merger
discussions. The parties decided to work toward a definitive merger agreement
in parallel with the continuation of a due diligence investigation by each
company into the business, operations and finances of the other company. On
April 9, 1997, Messrs. Bisceglia and Gray discussed the information each
company would need to conduct the due diligence review.
 
  At the Elcotel Board meeting held on April 14, 1997, Mr. James and Mr. Gray
informed the Elcotel Board that they had had informal preliminary discussions,
through Mr. Reisley of Cameron Associates, concerning a
 
                                      25
<PAGE>
 
possible merger with TSG. Messrs. James and Gray reported that TSG was in the
payphone and refurbishment business, with TSG's customer base consisting of
large telcos and some international customers. A business combination would be
complementary since Elcotel's strengths were in the independent payphone
operator market whereas TSG's biggest market was the telco market and
international wireless market. Preliminary discussions contemplated the merger
to be non-dilutive with an approximate one-to-one exchange of shares, giving
Elcotel stockholders approximately 62% and TSG stockholders approximately 38%
of the company after the merger. The Elcotel Board authorized Elcotel
management to proceed with a due diligence investigation of TSG.
 
  At the TSG Board meeting held on April 15, 1997, Mr. Bisceglia reported to
directors on the April7 meeting in New York City. After a discussion, the TSG
Board decided that all but the most sensitive due diligence investigation
should be completed by both companies before signing a definitive merger
agreement. The TSG Board also discussed the advisability of retaining a firm
knowledgeable in the industry to do an independent analysis of Elcotel and its
technology so that the TSG Board could be as fully informed as possible. In
that connection, the TSG Board authorized management to retain Corporate
Builders L.P. through one of its principals, Glenn Bierman, an individual who
had done an analysis of Elcotel for TSG in the past. At this meeting, Mr.
Plaumann reported that his discussions with Elcotel on behalf of Wexford were
centering on an exchange ratio of 1.05 shares of Elcotel Common Stock for each
share of TSG.
 
  During the week of May 12, 1997, Elcotel personnel and its counsel visited
the New York offices of TSG's counsel to review various due diligence
materials of TSG. TSG personnel conducted a similar due diligence review at
the Philadelphia offices of Elcotel's counsel the following week.
 
  On May 16, 1997, TSG's Board met to review the proposed merger and received
a preliminary report from Glenn Bierman in which he reviewed the work he had
done to date and indicated that in his view the merger as proposed would be
beneficial to TSG.
 
  On May 22, 1997, the Elcotel Board met, and Mr. Gray updated the Elcotel
Board on the results of the due diligence review held the previous week at the
New York offices of TSG's counsel and further discussions with TSG about a
possible merger. After discussions, the Elcotel Board unanimously determined
that the proposal to merge the two companies was unacceptable as presented,
due to Elcotel's concern about TSG's ability to achieve its revenue
projections and to improve its gross margins. The Elcotel Board voted to cease
the due diligence review.
 
  After the Elcotel Board meeting, Mr. Reisley informed Mr. Plaumann of
Elcotel's concerns. At Mr. Plaumann's suggestion, he and Mr. Bisceglia met
with Mr. Gray and Mr. Reisley on June 4, 1997 to discuss Elcotel's concerns.
Mr. Bisceglia provided additional details on the potential to increase
revenues and improve gross margins, and information on a new contract not
included in its business plan, all of which attempted to address the concerns
raised by Elcotel.
 
  At the June 9, 1997 meeting of the Elcotel Board, Mr. James advised the
Elcotel Board that since its May 22, 1997 meeting, Mr. Gray and Mr. Bisceglia
had had further discussions, and that TSG had provided additional information
to Elcotel to support TSG's potential to increase its revenues and improve
gross margins. Mr. Gray discussed TSG's revenue sources, TSG's technology and
the basis for potential gross margin improvements. He also described TSG's new
smart phone board and the potential markets for that product. Mr. James
requested authority to proceed with the due diligence review of TSG and to
have Elcotel management report the results to the Elcotel Board. After
extensive discussion, the Elcotel Board concluded that it was advisable to
allow management to proceed with the due diligence review in order to evaluate
whether there was an opportunity for Elcotel to increase shareholder value.
All members of the Elcotel Board voted in favor of the motion, except Mr.
Thomas Wiltse, who voted against. Mr. Wiltse stated that Elcotel should focus
on its current business plan, and that pursuing the merger with TSG could have
an adverse impact on Elcotel's ability to implement its business plan. Mr.
Wiltse expressed continued concerns about TSG's ability to achieve its
projections, the level of TSG's debt and the amount of goodwill created by the
proposed transaction. Mr. Wiltse made a written submission to the Elcotel
Board, dated June 9, 1997, explaining his position.

  At TSG's Board meeting held on June 24, 1997, Mr. Bisceglia reported to the
TSG Board on the progress of TSG's due diligence investigation of Elcotel. Mr.
Bierman of Corporate Builders L.P. joined the meeting to brief directors on
his analysis of Elcotel and TSG and to report that in his view the proposed
merger with Elcotel would be advantageous for TSG from a financial, business
and technological point of view. The TSG Board then discussed at length the
merits of the proposed merger, including that the stock of both companies is
thinly traded and that the stock prices of the companies are not indicative of
their values. The TSG Board also noted that Elcotel has a large number of
customers, growth in its international sales, and excellent margins, while by
comparison, TSG has a relatively smaller number of larger customers, lower
margins, and is only starting to penetrate international markets. The Board
then decided to continue with the merger negotiations on the basis of the
proposed 1.05 to 1 exchange ratio. The TSG Board also considered whether to
seek a fairness opinion from an investment bank with respect to the proposed
merger. In concluding that it was not necessary or useful to do so, the Board
took into account the work done to date by Corporate Builders L.P. to evaluate
the proposed merger, the familiarity of TSG's management with Elcotel arising
from the discussions held in 1994, and the strategic (as opposed to the purely
financial) reasons, for the merger. The Board decided that it should obtain
some general financial advice and support in connection with the ongoing
negotiations and decided to retain Wexford Management to provide analytical
support, liaison with Elcotel's representatives, and assistance with
negotiations and valuations for a fee of $200,000 (including expenses) payable
only if the Merger is consummated. See "The Merger--Interests of Certain
Parties and Employee Matters."
 
  On July 14, 1997, Mr. Bisceglia and William Thompson, Chief Financial
Officer of TSG, attended an Elcotel Board meeting at the invitation of Mr.
Gray. Mr. Bisceglia made a presentation describing TSG's domestic and
international markets, and answered questions from Elcotel Board members. Mr.
James explained the reasons he believed the merger was a sound strategy to
increase shareholder value. He stated that the combination of Elcotel and TSG
would create a company that would be the largest supplier of payphone products
in the United States and that the combined company could gain critical mass in
the international markets. He further stated that the merger was advisable due
to the economies of scale to be realized. A motion was approved to give
management authority to negotiate and enter into a definitive merger
agreement, subject to obtaining a fairness opinion, director review of the
definitive agreement and completion of a due diligence and financial review.
Messrs. Gray, James, Jasmann, Moore and Patton voted for the motion and Mr.
Suplee voted against the motion, stating that he was in favor of the Merger,
but that the purchase price was too high. Mr. Wiltse was not present at the
meeting.
 
  On July 16, 1997, the TSG Board met to discuss the formal written report of
Corporate Builders L.P., a due diligence analysis of Elcotel prepared by the
management of TSG, and some comparative analyses prepared by Wexford
Management. At the meeting, Mr. Bisceglia advised the directors of an informal
agreement concerning the composition of the post-merger board of directors.
Directors decided that both the board structure and the composition of senior
management should be made a formal part of the merger agreement so that TSG's
stockholders would have assurance as to the management of the combined
entities for at least the first year after the Merger. Mr. Plaumann reported
to the Board that he had found little information about comparable companies
against which to measure Elcotel and its relative value to TSG. The Board then
voted to proceed with negotiations and formally approved the agreement by
which Wexford Management was engaged as the TSG financial advisor.
 
  At the July 22, 1997 telephonic meeting of the Elcotel Board, Mr. Gray
reported on TSG's current sales projections and TSG's backlog of domestic
sales. He also reported that TSG had signed a new sales contract with an RBOC
that was expected to provide incremental revenue not reflected in TSG's
projections. Members of the Elcotel Board discussed TSG's ability to achieve
its forecasts. The Board discussed several firms as possible candidates to
deliver a fairness opinion, and approved the selection of Murray Devine.
 
  On July 31, 1997 members of Elcotel's management visited TSG's Roswell,
Georgia headquarters to review strategy for the combined entity and to discuss
technology, product and customer issues.
 
                                      27
<PAGE>
 
  At its August 5, 1997 meeting, the Elcotel Board discussed the near final
draft of the Merger Agreement and related documents. Several due diligence
reports were presented. Representatives of Murray Devine orally advised the
Elcotel Board that in Murray Devine's opinion, the Merger was fair, from a
financial point of view, to Elcotel. Murray Devine also discussed the
procedures it had performed and its analysis. The Elcotel Board discussed
various questions raised by individual board members. After extensive
discussion, the Elcotel Board approved the current draft of the Merger
Agreement and the Merger by a vote of 5 to 2. Messrs. Gray, James, Jasmann,
Moore and Patton voted to approve the Merger and Messrs. Suplee and Wiltse
voted against.
 
  On August 11, 1997, the TSG Board held a special meeting to review a near
final draft of the Merger Agreement, the Voting Agreement and both companies'
disclosure schedules. Directors discussed some of the key merger terms,
including the Exchange Ratio, the treatment of warrant and option holders, the
representations, warranties and covenants being made by TSG in the Merger
Agreement, the terms under which the Merger Agreement may be terminated by one
or both of the parties, and the effect on the Merger of the Voting Agreement.
Mr. Bisceglia noted that he had been informed that Elcotel's financial adviser
had rendered an affirmative opinion as to the fairness of the Merger Agreement
to the stockholders of Elcotel from a financial point of view and that the
Elcotel Board had approved the Merger Agreement. At the end of the meeting,
TSG's directors adopted formal resolutions by which they stated their opinion
that the terms of the Merger are fair and in the best interests of TSG and its
stockholders; authorized management to sign the Merger Agreement on behalf of
TSG; granted to management the authority to negotiate improvements in the
terms and conditions to the extent they are able to do so; and authorized the
call of a meeting of stockholders to consider the approval of the Merger.
 
  On August 13, 1997, representatives of Elcotel and TSG executed the Merger
Agreement, and Fundamental, Wexford and Elcotel and the other parties executed
the Voting Agreement. On August 14, 1997, Elcotel and TSG each issued a press
release announcing the proposed Merger.
 
ELCOTEL'S REASONS FOR THE MERGER; RECOMMENDATION OF THE ELCOTEL BOARD
 
  The Elcotel Board has approved the Merger Agreement and recommended that the
stockholders of Elcotel vote to approve the issuance of Elcotel Common Stock
pursuant to the Merger Agreement and any other actions required in furtherance
of the Merger. In reaching its conclusion, the Elcotel Board considered a
number of factors, including:
 
  .  The judgment and advice of Elcotel's senior management, including in
     respect of the conditions in the payphone industry and the strategic
     options available to Elcotel.
 
  .  The oral analyses and opinion of Murray Devine presented to the Elcotel
     Board on August 5, 1997 and written opinion dated August 5, 1997, to the
     effect that as of such date the Exchange Ratio is fair to the
     stockholders of Elcotel from a financial point of view. A copy of the
     written opinion dated August 5, 1997 of Murray Devine, setting forth the
     assumptions made, factors considered and scope of the review undertaken
     by Murray Devine, is attached as Appendix B hereto. Elcotel stockholders
     are urged to read the opinion of Murray Devine carefully and in its
     entirety. See "The Merger--Opinion of Murray Devine; Background of the
     Merger."
 
  .  The financial condition, results of operations and cash flows of Elcotel
     and TSG, both on a historical and a prospective basis.
 
  .  The terms and conditions of the Merger Agreement, including the amount
     and form of consideration to be paid pursuant to the Merger Agreement.
 
  .  Historical market prices and trading information with respect to Elcotel
     Common Stock and TSG Common Stock.
 
  .  The Voting Agreement which provides, among other things, for Fundamental
     to vote its shares of Elcotel Common Stock, and for Wexford to vote its
     shares of TSG Common Stock, in favor of adoption of the Merger
     Agreement.
 
                                      28
<PAGE>
 
  .  Complementary technologies and market positions of TSG and Elcotel.
 
  .  Ability of the combined company to take advantage of domestic and
     international sales opportunities.
 
  .  Increased interest from the investment community and an expanded trading
     market for Elcotel Common Stock.
 
  The foregoing discussion of the information and factors considered and given
weight by the Elcotel Board is not intended to be exhaustive. In view of the
variety of factors considered in connection with its evaluation of the Merger,
the Elcotel Board did not find it practicable to and did not attempt to rank
or assign relative weights to the foregoing factors. In addition, individual
members of the Elcotel Board may have given different weights to different
factors.
 
  Elcotel's business combination with TSG pursuant to the Merger is an
integral part of Elcotel's strategy to expand into the telco markets
domestically, improve its cellular based technology for international
applications and establish a service capability related to payphone repair,
reconditioning and refurbishing. Elcotel's acquisition of TSG pursuant to the
Merger supports a number of important strategic objectives of Elcotel. Elcotel
believes the Merger will enable Elcotel to achieve market diversification, and
in particular, to provide Elcotel with a meaningful share of the market for
sales of payphones to RBOCs which it has yet to penetrate. Elcotel believes
the Merger will position Elcotel as a major supplier to both domestic and
international payphone markets offering a more complete line of products.
 
  Following the Merger, as soon as reasonably practicable, Elcotel expects to
rename all TSG entities Elcotel-TSG and integrate them with Elcotel's
operations. Elcotel believes the elimination of duplicate overhead expenses
may result in a reduction in annual combined operating costs, beginning during
the six-month period after the Effective Time. In addition, Elcotel believes
that there are other cost reductions and cost avoidance opportunities
presented by the Merger (including eliminating duplicate sales and marketing
activities, eliminating duplicate development programs, achieving
manufacturing cost reductions from higher volume and improvements in TSG's
processes, and reducing inventories and manufacturing overhead expenses), as
well as opportunities for enhanced revenue growth from the telephone companies
in the domestic and international markets. Elcotel believes that the potential
cost reductions from the integration of TSG's business, the avoidance of costs
and expenses that would be incurred by TSG and Elcotel as separate entities,
and the potential revenue enhancements will enable the combined business to
absorb the amortization of intangible assets, including goodwill, resulting
from the Merger. However, there can be no assurance in that regard.
 
  THE ELCOTEL BOARD BY A VOTE OF 5 TO 2 HAS RECOMMENDED THAT THE HOLDERS OF
ELCOTEL COMMON STOCK VOTE "FOR" ADOPTION OF THE ISSUANCE OF ELCOTEL COMMON
STOCK PURSUANT TO THE MERGER AGREEMENT AND ANY OTHER ACTIONS REQUIRED IN
FURTHERANCE OF THE MERGER.
 
OPINION OF MURRAY DEVINE
 
  Elcotel engaged Murray Devine to act as its financial advisor in connection
with the transactions contemplated by the Merger Agreement based upon Murray
Devine's qualifications, expertise and reputation. On August 5, 1997, Murray
Devine rendered an oral opinion to the Elcotel Board which was confirmed by
delivery of its written opinion dated August 5, 1997 (the "Murray Devine
Opinion") to the effect that, as of such date, and based upon and subject to
the assumptions, limitations and qualifications set forth in such opinion, the
Merger pursuant to the Merger Agreement is fair, from a financial point of
view, to Elcotel.
 
  THE FULL TEXT OF THE MURRAY DEVINE OPINION IS SET FORTH AS APPENDIX B TO
THIS JOINT PROXY STATEMENT-PROSPECTUS AND SHOULD BE READ CAREFULLY IN ITS
ENTIRETY, INCLUDING WITHOUT LIMITATION THE DESCRIPTIONS OF THE PROCEDURES
FOLLOWED, ASSUMPTIONS MADE, OTHER MATTERS CONSIDERED AND LIMITATIONS OF THE
REVIEW UNDERTAKEN IN ARRIVING AT SUCH OPINION. THE MURRAY DEVINE OPINION
ADDRESSES
 
                                      29
<PAGE>
 
THE FAIRNESS OF THE MERGER TO ELCOTEL FROM A FINANCIAL POINT OF VIEW AND DOES
NOT CONSTITUTE A RECOMMENDATION TO ANY STOCKHOLDER OF ELCOTEL OR TSG AS TO HOW
SUCH STOCKHOLDER SHOULD VOTE AT THE ELCOTEL ANNUAL MEETING OR TSG SPECIAL
MEETING.
 
  The Murray Devine Opinion does not constitute an opinion as to the price at
which Elcotel Common Stock will actually trade at any time. The type and
amount of consideration was determined in arm's length negotiations between
Elcotel and TSG in which negotiations Cameron Associates, not Murray Devine,
advised Elcotel. No restrictions or limitations were imposed upon Murray
Devine with respect to the investigations made or procedures followed by
Murray Devine in rendering its opinion. In arriving at its opinion, Murray
Devine, among other things: (i) reviewed the Merger Agreement and other
related documents; (ii) reviewed such publicly available business and
financial information relating to Elcotel and TSG as Murray Devine deemed
appropriate; (iii) reviewed certain internal financial and operating
information relating to Elcotel and TSG (including financial plans) prepared
by their respective managements; (iv) discussed the past and current
operations and financial condition and prospects of Elcotel with the senior
management of Elcotel; (v) discussed the past and current operations and
financial condition and prospects of TSG with the senior management of TSG;
(vi) reviewed pro forma financial statements (including financial plans) of
Elcotel and TSG on a combined basis (the "Combined Companies") prepared
jointly by the management of Elcotel and TSG; and (vii) reviewed recent stock
market data relating to Elcotel and TSG. In addition, Murray Devine compared
certain financial and securities data of Elcotel and TSG with various other
companies whose securities are traded in public markets and conducted such
other financial studies, analyses and investigations as Murray Devine deemed
appropriate for purposes of rendering its opinion.
 
  In rendering its opinion, Murray Devine did not independently verify any of
the foregoing information and relied on its being complete and accurate in all
material respects and further relied upon the assurances of Elcotel management
that they are unaware of any facts that would make the information provided to
Murray Devine incomplete or misleading in any material respect. Murray Devine
also assumed that the financial plans have been reasonably prepared on a basis
reflecting the best currently available estimates and judgments of Elcotel's
and TSG's management as to the expected future financial performance of
Elcotel and TSG. Murray Devine did not make any independent evaluation or
appraisal of the individual assets of Elcotel or TSG, nor was Murray Devine
furnished with any such appraisals.
 
  The Murray Devine opinion is necessarily based on economic, market,
financial and other conditions as they existed on, and on information made
available to it as of, the date of its opinion. Murray Devine does not have
any obligation to revise or reaffirm its opinion before the Effective Time or
thereafter.
 
  Murray Devine was selected to render an opinion in connection with the
Merger based upon Murray Devine's qualifications, expertise and reputation,
including the fact that Murray Devine, as part of its investment banking
business, is regularly engaged in the valuation of businesses and their
securities in connection with mergers and acquisitions, and valuations for
corporate and other purposes.
 
  Murray Devine received a non-contingent fee of $100,000.
 
TSG'S REASONS FOR THE MERGER; RECOMMENDATION OF THE TSG BOARD
 
  On August 11, 1997, the TSG Board, by unanimous vote, approved the Merger
Agreement and the transactions contemplated thereby (including the Merger) and
decided to recommend adoption of the Merger Agreement and the transactions
contemplated thereby to TSG's stockholders. In reaching these conclusions, the
TSG Board considered, among other things, the following factors:

  .  Historical market prices and trading information with respect to Elcotel
     Common Stock and TSG Common Stock.
 
  .  The Voting Agreement which provides, among other things, for Wexford to
     vote its shares of TSG Common Stock and for Fundamental to vote its
     shares of Elcotel Common Stock, in favor of adoption of the Merger
     Agreement.
 
  The foregoing discussion of the information and factors considered by the
TSG Board is not intended to be exhaustive, but includes material factors
considered by the Board. In reaching its determination to approve the Merger
Agreement and the transactions contemplated thereby, the TSG Board did not
assign any relative or specific weights to the various factors considered by
it nor did it specifically characterize any factor as positive or negative
(except as described above), and individual directors may have given different
weights to different factors and may have viewed certain factors more
positively or negatively than others.
 
  TSG's merger with Elcotel is an essential element of TSG's strategy to build
critical mass, broaden its customer base and enhance its product offering.
TSG's strategy to combine with Elcotel is reflective of the combined
companies' strategy to become a leading global provider of public
communications products and services.
 
  FOR THE REASONS DESCRIBED ABOVE, THE TSG BOARD UNANIMOUSLY RECOMMENDS THAT
THE HOLDERS OF TSG COMMON STOCK VOTE "FOR" APPROVAL OF THE MERGER AGREEMENT
AND THE APPROVAL OF ANY OTHER ACTIONS REQUIRED IN FURTHERANCE OF THE MERGER.
 
CERTAIN FEDERAL INCOME TAX CONSEQUENCES
 
  Following is a summary of material federal income tax consequences of the
Merger based on current law. Neither Elcotel nor TSG has requested or will
request any ruling from the IRS as to the United States federal income tax
consequences of the Merger. Future legislative, judicial or administrative
changes or interpretations, which may be retroactive, could alter or modify
the statements set forth herein. This summary may not apply to certain classes
of taxpayers, including, without limitation, insurance companies, tax-exempt
organizations, financial institutions, dealers in securities, nonresident
aliens, foreign corporations, persons who acquired shares of TSG Common Stock
pursuant to the exercise of employee stock options or rights or otherwise as
compensation, and persons who hold shares of TSG Common Stock in a hedging
transaction or as part of a straddle or conversion transaction. Also, this
summary does not address state, local or foreign tax consequences of the
Merger. Consequently, each holder of TSG Common Stock (a "Holder") should
consult such Holder's own tax advisor as to the specific tax consequences of
the Merger to such Holder.
 
  The Merger is intended to be treated as a "reorganization" within the
meaning of Section 368(a) of the Code. Accordingly, for federal income tax
purposes, no income, gain or loss will be recognized by either Elcotel or TSG
as a result of the Merger, and Holders who exchange shares of TSG Common Stock
for shares of Elcotel Common Stock pursuant to the Merger will be treated as
follows: (i) no income, gain or loss will be recognized by a Holder with
respect to the receipt of Elcotel Common Stock; (ii) the aggregate adjusted
tax basis of shares of Elcotel Common Stock (including a fractional share
interest in Elcotel Common Stock deemed received and redeemed as described in
(iv) below) received by a Holder will be the same as the aggregate adjusted
tax basis of the shares of TSG Common Stock exchanged therefor; (iii) the
holding period of shares of Elcotel Common Stock (including the holding period
of a fractional share interest in Elcotel Common Stock deemed received and
redeemed as described in (iv) below) received by a Holder will include the
holding period of the TSG Common Stock exchanged therefor, provided that such
shares of TSG Common Stock are held as capital assets at the Effective Time;
and (iv) a Holder of TSG Common Stock who receives cash in lieu of a
fractional share interest in Elcotel Common Stock will be treated as having
received such fractional share interest and then as having received the cash
in redemption of such fractional share interest.
 
                                      31
<PAGE>
 
  It is a condition to the consummation of the Merger that TSG receive an
opinion of counsel to the effect that neither TSG nor any of its stockholders
will recognize gain or loss for United States federal income tax purposes as a
result of the Merger (other than in respect of any cash paid in lieu of
fractional shares). The opinion referred to in this paragraph will be based
upon certain facts, assumptions and representations and/or covenants,
including those contained in certificates of officers of Elcotel, TSG and,
possibly, others. If such opinion is not received, the Merger will not be
consummated unless the condition requiring its receipt is waived. TSG
currently anticipates that such opinion will be delivered and that TSG will
not waive the condition requiring receipt of such opinion. Such opinion will
not be binding upon the IRS and no assurance can be given that the IRS will
not take a contrary position.
 
  Conversion pursuant to the Merger Agreement of the TSG Stock Options into
options to acquire Elcotel Common Stock should not change the federal income
tax treatment of the TSG Stock Options. The conversion is intended to satisfy
Section 424(a) of the Internal Revenue Code, so that it will not constitute a
modification of the TSG Stock Options. In the absence of a modification, the
date the TSG Stock Options were granted will continue to be considered the
date of grant, for purposes of qualifying for favorable federal income tax
treatment upon disposition of stock purchased pursuant to an incentive stock
option or the 1995 Employee Stock Purchase Plan.
 
INTERESTS OF CERTAIN PERSONS AND EMPLOYEE MATTERS
 
  In considering the recommendation of the Elcotel Board and the TSG Board
with respect to the Merger, stockholders of Elcotel and TSG should be aware
that certain members of the management of Elcotel and TSG and of the Elcotel
Board and the TSG Board have certain interests in the Merger that are in
addition to the interests of stockholders of Elcotel and TSG generally.
 
  Directorships. Pursuant to the Merger Agreement, Elcotel has agreed to
invite to become directors of Elcotel following the Merger: David Steadman,
who has an employment agreement with TSG and is Chairman of its Board of
Directors; Mark Plaumann, a member of the Board of Directors of TSG and Senior
Vice President of Wexford Management, an affiliate of Wexford, the holder of
approximately 52% of the outstanding TSG Common Stock; Kenneth Rubin, Vice
President of Wexford; and Vincent Bisceglia, President and Chief Executive
Officer of TSG, who will enter into an employment agreement with Elcotel in
connection with the Merger. During the period ending immediately after the
second annual meeting of Elcotel stockholders following this Elcotel Annual
Meeting, Fundamental and Wexford have agreed to vote their shares in favor of
any nominees for director of Elcotel nominated by the incumbent Elcotel Board.
See "Fundamental/Wexford Stockholders' Agreement--Voting of Capital Stock."
Immediately after the Merger, the Elcotel Board will include two
representatives of Fundamental, Mr. James and Charles Moore, and two
representatives of Wexford, Messrs. Plaumann and Rubin.
 
  Investment Banking Fee. Pursuant to an agreement entered into in July 1997,
TSG will pay a $200,000 investment banking fee to Wexford Management, an
affiliate of Wexford, the holder of approximately 52% of the outstanding TSG
Common Stock, for services rendered in connection with the Merger if the
Merger or other transaction involving the sale of all or substantially all of
TSG is consummated. In the event the Merger does not close, TSG has agreed to
reimburse Wexford Management for up to $5,000 of out-of-pocket costs and
expenses. At its option, Elcotel can pay the $200,000 fee to Wexford
Management by the issuance of 30,769 shares of Elcotel Common Stock.
 
  Treatment of Stock Options. The conversion pursuant to the Merger Agreement
of the TSG Stock Options into options to acquire Elcotel Common Stock will
result in adjustments to the per share exercise price and number of shares
subject thereto based on the Exchange Ratio. The Merger will result in the
acceleration and immediate vesting of: all outstanding TSG Stock Options
granted to Mr. Bisceglia and Mr. Steadman under TSG's 1994 Omnibus Plan
(options to purchase approximately 57,500 shares of TSG Common Stock,
including options to purchase 50,000 shares which otherwise vest on November
1, 1997) pursuant to the terms of their stock option agreements; 50% of
unvested TSG Stock Options granted to the other executive officers of TSG
 
                                      32
<PAGE>
 
(options to purchase approximately 48,750 shares of TSG Common Stock,
including 18,750 shares which otherwise vest on November 1, 1997) pursuant to
the terms of an Officers' Policy adopted by the TSG Board, and all outstanding
TSG Stock Options granted to TSG's directors under TSG's 1995 Non-Employee
Director Plan (options to purchase approximately 12,000 shares of TSG Common
Stock) pursuant to the terms of the plan and their stock option agreements.
All other options outstanding under TSG Stock Options will vest according to
their terms.
 
  Employment Agreements. In connection with the Merger, Elcotel has entered
into employment agreements with each of Vincent Bisceglia, President and Chief
Executive Officer of TSG, C. Shelton James, Chief Executive Officer of Elcotel
and Chairman of its Board of Directors, and Tracey Gray, President of Elcotel.
See "The Merger Agreement--General Conditions Precedent to the Merger." Mr.
James will be elected Chairman of the Board of Directors of Elcotel, will
receive an annual salary of not less than $94,000, subject to annual increase,
and will be entitled to an annual incentive bonus computed as a percentage of
base salary based on whether certain performance goals are met and additional
stock options as approved by the Compensation and Stock Committee of the
Elcotel Board. Mr. Gray will be elected President and Chief Executive Officer
of Elcotel, will receive an annual salary of not less than $170,000, subject
to annual increase, and will be entitled to an annual incentive bonus computed
as a percentage of base salary based on whether certain performance goals are
met and additional stock options as approved by the Compensation and Stock
Committee of the Elcotel Board. Mr. Bisceglia will be elected Executive Vice
President and Chief Operating Officer (or, at Elcotel's choice, to a higher
office), will receive an annual salary of not less than $160,000, subject to
annual increase, and will be entitled to retain all options granted to him as
an employee of TSG that will be converted to options to purchase Elcotel
Common Stock (see "The Merger Agreement--Conversion of Options to Purchase TSG
Common Stock), an additional option to purchase 50,000 shares of Elcotel
Common Stock and an incentive bonus for Elcotel's fiscal year ending March 31,
1998 equal to 2% of TSG's operating profits (defined as net income before
taxes, amortization, depreciation, interest, gains and losses arising from
revaluation of assets, and effects of the Merger on TSG's operations). For
fiscal years beginning after March 31, 1998, Mr. Bisceglia will be entitled to
participate in any bonus program maintained for senior executives of Elcotel
to the same extent and on the same terms as the Chief Executive Officer of
Elcotel. After a transition period ending seven months after the consummation
of the Merger, Mr. Bisceglia will be required to relocate his residence to the
Sarasota, Florida area. Elcotel will reimburse Mr. Bisceglia for certain
expenses in connection with such relocation. Mr. Bisceglia's employment
agreement with Elcotel will supercede any prior employment agreements with
TSG. Each of these employment agreements of Elcotel will continue until
December 31, 1998, subject to earlier termination for cause or for certain
other reasons. Each employment agreement will continue for additional one-year
periods thereafter unless Elcotel gives written notice of nonrenewal at least
180 days prior to the end of any such period. Upon non-renewal of the
employee's employment term or the employee's death or permanent disability,
the employee will be entitled to severance equal to six months (or, for Mr.
Bisceglia if he has relocated his residence to Sarasota, Florida, one year) of
salary and benefits and any bonus and stock options to which such employee is
entitled. Elcotel may terminate the employee's employment without cause if
Elcotel pays the employee severance as described in the preceding sentence for
at least one year. Pursuant to these agreements, each employee is indemnified
by Elcotel with respect to claims made against him as a director, officer
and/or employee of Elcotel or any subsidiary of Elcotel to the fullest extent
permitted by Elcotel's Certificate of Incorporation, its Bylaws or Delaware
Law.
 
  Registration Rights. Pursuant to the Fundamental/Wexford Stockholders'
Agreement, Wexford, Acor S.A., a holder of approximately 9.7% of the
outstanding TSG Common Stock, and Fundamental will receive certain
registration rights with respect to Elcotel Common Stock beneficially owned by
them, including the Elcotel Common Stock issued to Wexford pursuant to the
Merger. See "Fundamental/Wexford Stockholders' Agreement--Registration
Rights."
 
REFINANCING OF TSG AND ELCOTEL INDEBTEDNESS
 
  Elcotel intends to refinance with one bank the existing indebtedness of TSG
to its bank and of Elcotel to its bank in connection with the consummation of
the Merger. Elcotel believes it will require a revolving line of credit of
approximately $15 million. There can be no assurance whether it will be able
to obtain such a line of credit or as to the terms of such line of credit.
 
 
                                      33
<PAGE>
 
ACCOUNTING TREATMENT
 
  The Merger will be accounted for under the "purchase" method of accounting
in accordance with generally accepted accounting principles ("GAAP").
Accordingly, the merger consideration will be allocated to the assets and
liabilities of TSG based on their estimated fair values with the excess
recorded as goodwill. See "Unaudited Pro Forma Consolidated Financial
Information."
 
ANTITRUST
 
  No filing in respect of the Merger is required under the Hart-Scott-Rodino
Antitrust Improvements Act of 1976, as amended.
 
NO APPRAISAL OR DISSENTERS' RIGHTS
 
  Under Delaware Law, holders of TSG Common Stock are not entitled to
appraisal or dissenters' rights in connection with the Merger because the TSG
Common Stock is designated as a National Market security on an interdealer
quotation system by the NASD and the consideration which such holders will be
entitled to receive in the Merger will consist solely of (i) Elcotel Common
Stock, which will also be designated as a National Market security on an
interdealer quotation system by the NASD, and (ii) cash in lieu of fractional
shares. Under Delaware Law, holders of Elcotel Common Stock are not entitled
to appraisal or dissenters' rights in connection with the Merger because
Elcotel is not a constituent corporation to the Merger.
 
RESALES OF ELCOTEL COMMON STOCK
 
  All shares of Elcotel Common Stock issued pursuant to the Merger will be
freely transferable, except that shares of Elcotel Common Stock received by
any person who may be deemed to be an "affiliate" of TSG prior to the Merger
(for purposes of Rule 145 promulgated under the 1933 Act) may not be resold
except in transactions permitted by Rule 145 or as otherwise permitted under
the 1933 Act. Persons deemed to be affiliates of TSG are those individuals or
entities that control, are controlled by, or are under common control with,
such party and generally include executive officers and directors of such
party as well as certain principal stockholders of such party.
 
  TSG has agreed to deliver to Elcotel, at least 30 days before the Effective
Time, a letter identifying all persons who are, at the time of the TSG Special
Meeting, deemed to be "affiliates" (as defined in the preceding paragraph) of
TSG, and to use its best efforts to cause each person so identified to deliver
to Elcotel at or before the Effective Time, a written agreement substantially
in the form previously approved by Elcotel and TSG, providing that such person
will not sell, pledge, transfer or otherwise dispose of any Elcotel Common
Stock received by such person in exchange for shares of TSG Common Stock
pursuant to the Merger, except pursuant to an effective registration statement
or in compliance with such Rule 145 or another exemption from the registration
requirements of the 1933 Act. Elcotel will be entitled to issue appropriate
stop transfer instructions to the transfer agent for the Elcotel Common Stock
to be issued to such affiliates pursuant to the Merger, consistent with the
terms of such letter. This Joint Proxy Statement-Prospectus does not cover any
resale of Elcotel Common Stock received by affiliates of TSG in connection
with the Merger. Pursuant to the Fundamental/Wexford Stockholders' Agreement,
Wexford and Acor S.A., a holder of approximately 9.7% of the outstanding TSG
Common Stock, have been granted certain registration rights with respect to
the resale of Elcotel Common Stock. See "Fundamental/Wexford Stockholders'
Agreement."
 
NASDAQ NATIONAL MARKET
 
  Elcotel will use its best efforts to cause the shares of Elcotel Common
Stock to be issued in connection with the Merger to be approved for listing on
the Nasdaq National Market at or prior to the Effective Time.

                             THE MERGER AGREEMENT
 
  The following summary of the Merger Agreement contained in this Joint Proxy
Statement-Prospectus is not intended to be a complete description of the terms
and conditions thereof and is qualified in its entirety by reference to the
full text thereof, which is incorporated herein by reference and a copy of
which is attached hereto as Appendix A. Unless otherwise defined in this Joint
Proxy Statement-Prospectus, the capitalized terms used in this section have
the meanings ascribed thereto in the Merger Agreement.
 
GENERAL
 
  The Merger Agreement provides that, subject to the terms and conditions
thereof and in accordance with Delaware law, at the Effective Time, Elcotel
and TSG will consummate the Merger pursuant to which (i) Merger Subsidiary
will be merged with and into TSG and the separate corporate existence of
Merger Subsidiary will thereupon cease, and (ii) TSG, the surviving
corporation, will become a direct wholly-owned subsidiary of Elcotel and will
continue to be governed by the laws of the State of Delaware.
 
EFFECTIVE TIME
 
  The Effective Time of the Merger will be at such time as the certificate of
merger is filed with the Delaware Secretary of State, or at such later time as
Elcotel and TSG agree and specify in the certificate of merger. The filing of
the certificate of merger will occur no later than the fifth business day
after satisfaction or waiver of the conditions precedent to the consummation
of the Merger. See "The Merger Agreement--General Conditions Precedent to the
Merger." Elcotel and TSG currently anticipate that the Effective Time will
occur on or before December 31, 1997. However, there can be no assurance that
the conditions to the Merger will be satisfied by such date or at all, or that
the Merger Agreement will not be terminated.
 
CORPORATE MATTERS
 
  The certificate of incorporation of Merger Subsidiary will be the
certificate of incorporation of the surviving corporation, except that, at the
Effective Time, the name of the surviving corporation will 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.
 
  The bylaws of Merger Subsidiary in effect at the Effective Time will 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.
 
CONVERSION OF TSG SHARES
 
  The Merger Agreement provides that each share of TSG Common Stock issued and
outstanding immediately prior to the Effective Time (other than TSG Common
Stock owned by TSG as treasury stock, and, if any, TSG Common Stock owned by
Elcotel or any direct or indirect wholly-owned subsidiary of Elcotel or TSG)
will, at the Effective Time, by virtue of the Merger and without any action on
the part of the holder thereof, be converted into the right to receive 1.05
shares of fully paid and nonassessable Elcotel Common Stock (such conversion
rate, the "Exchange Ratio").
 
  In lieu of any fractional share of Elcotel Common Stock to which a holder of
TSG Common Stock would be entitled, Elcotel will pay to each former
stockholder of TSG who otherwise would be entitled to receive a fractional
share of Elcotel Common Stock an amount in cash determined by multiplying (i)
such fraction by (ii) the arithmetic mean of the closing sales prices for the
Elcotel Common Stock reported on the Nasdaq National Market for each of the
five 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.
 
                                      35
<PAGE>
 
  All shares of TSG Common Stock owned by TSG as treasury stock and any shares
of TSG Common Stock owned by Elcotel or any direct or indirect wholly owned
subsidiary of Elcotel will, at the Effective Time, be canceled and retired and
will cease to exist and no Elcotel Common Stock will be delivered in exchange
therefor.
 
  The Merger Agreement provides that, on and after the Effective Time, holders
of certificates which immediately prior to the Effective Time represented
outstanding shares of TSG Common Stock (the "Certificates") will cease to have
any rights as stockholders of TSG, except the right to receive the
consideration set forth in the Merger Agreement for each share of TSG Common
Stock held by them.
 
  BEFORE THE EFFECTIVE TIME, ELCOTEL WILL APPOINT AN AGENT FOR THE PURPOSE OF
EXCHANGING CERTIFICATES REPRESENTING TSG COMMON STOCK FOR THE MERGER
CONSIDERATION (THE "EXCHANGE AGENT"). WITHIN FIVE BUSINESS DAYS AFTER THE
EFFECTIVE TIME, ELCOTEL OR THE EXCHANGE AGENT WILL MAIL TO EACH HOLDER OF
RECORD OF A CERTIFICATE WHOSE SHARES OF TSG COMMON STOCK WERE CONVERTED IN THE
MERGER INTO THE RIGHT TO RECEIVE ELCOTEL COMMON STOCK A LETTER OF TRANSMITTAL
AND INSTRUCTIONS FOR USE IN EFFECTING THE SURRENDER OF SUCH CERTIFICATES IN
EXCHANGE FOR ELCOTEL COMMON STOCK.
 
  TSG STOCKHOLDERS SHOULD NOT FORWARD TSG STOCK CERTIFICATES TO THE EXCHANGE
AGENT UNTIL THEY HAVE RECEIVED SUCH TRANSMITTAL LETTERS. TSG STOCKHOLDERS
SHOULD NOT RETURN STOCK CERTIFICATES WITH THE ENCLOSED PROXY.
 
CONVERSION OF OPTIONS TO PURCHASE TSG COMMON STOCK
 
  In accordance with the Merger Agreement, at the Effective Time, each
outstanding TSG Stock Option, whether vested or unvested, will be converted
into an option to acquire, on the same terms and conditions as were applicable
under the TSG Stock Option, a number of shares of Elcotel Common Stock equal
to 1.05 times the number of shares of TSG Common Stock which the option holder
was entitled to purchase immediately prior to the Effective Time under such
TSG Stock Option, 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 the TSG Stock Option divided by (ii) the aggregate
number of shares of Elcotel Common Stock deemed purchasable pursuant to the
TSG Stock Option, with any fractional share of Elcotel Common Stock resulting
from such calculation for such holder being rounded up to the nearest whole
share. However, in the case of any option to which Section 421 of the Internal
Revenue Code applies by reason of such option's qualification under Section
422 or 423 of the Code, the option price, the number of shares purchasable
pursuant to such option and the terms and conditions of exercise of such
option will be determined in order to comply with Section 424 of the Code.
 
  Elcotel will prepare and file with the Commission 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 TSG Option Plans and will use
its reasonable efforts to have such registration statement declared effective
as soon as practicable following the Effective Time.
 
CONVERSION OF WARRANTS TO PURCHASE TSG COMMON STOCK
 
  In accordance with the Merger Agreement, at the Effective Time, the TSG
Underwriter Warrants and each TSG Public Warrant (which in the aggregate
provide for the right to acquire 675,000 shares of TSG Common Stock) will
become a warrant to acquire, at a proportionately reduced exercise price per
share, a number of shares of Elcotel Common Stock equal to 1.05 times the
number of shares of TSG Common Stock that the warrant holder was entitled to
purchase immediately prior to the Effective Time under such TSG Warrants.
 
CONDUCT OF TSG PENDING THE MERGER
 
  In the Merger Agreement, TSG has agreed that, until the Effective Time,
except as expressly provided in the Merger Agreement or with the prior written
consent of Elcotel (which approval will not be unreasonably

CONDUCT OF ELCOTEL PENDING THE MERGER
 
  In the Merger Agreement, Elcotel has agreed that until the Effective Time,
except as expressly provided in the Merger Agreement or with the prior written
consent of TSG (which consent will not be unreasonably withheld or delayed
with respect to (c), (d), (h), (i), (j), (n) or (o), or (k) as it applies to
filing an amended tax return):
 
    (a) Elcotel will not adopt or propose any change in its Certificate of

part of the non-terminating party set forth in the Merger Agreement, or in the
event of non-occurrence of a condition precedent to the terminating party's
obligations (see "The Merger Agreement--Conditions Precedent to Obligations of
Elcotel; Conditions Precedent to Obligations of TSG"); or (iv) in the event a
court order is issued restricting or prohibiting the Merger; (c) by TSG if (i)

recommended a superior proposal to the stockholders of TSG or TSG shall have
entered into a definitive agreement providing for a superior proposal with a
person other than Elcotel.
 
TERMINATION FEES AND EXPENSES
 
  If the Merger Agreement is terminated because the TSG Board has determined
that termination is required for the TSG Board to comply with its fiduciary
duties to stockholders by reason of an unsolicited superior proposal having
been made or the TSG Board or recommends such a proposal to its stockholders,
or TSG enters into an agreement providing for such a superior proposal, then
TSG must pay Elcotel a termination fee of $1,300,000. If either party
terminates the Merger Agreement because the stockholders of TSG have voted not
to approve the Merger and prior to such termination any person or group has
made an alternative proposal, or if Elcotel terminates the Merger Agreement
because the TSG Board has withdrawn or modified its favorable recommendation
of the Merger in a manner materially adverse to Elcotel, then TSG must pay to
Elcotel up to $500,000 for Elcotel's out-of-pocket expenses relating to the
Merger Agreement. Elcotel must pay TSG's out-of-pocket expenses in an amount
up to $500,000 if either party terminates the Merger Agreement because Elcotel
has failed to obtain the approval of its stockholders, or if TSG terminates
the Merger Agreement because the Elcotel Board has withdrawn or modified its
favorable recommendation of the Merger in a manner materially adverse to TSG.
The same out-of-pocket expenses must be paid by the non-terminating party when
either party terminates the Merger Agreement in the event of certain material
breaches of the Merger Agreement on the part of the non-terminating party or
certain conditions precedent to the terminating party's obligations under the
Agreement have not been fulfilled. Additionally, under a manufacturing
agreement between Elcotel and TSG
 
                                      43
<PAGE>
 
dated September 26, 1997, Elcotel is obligated to reimburse TSG for certain
costs in establishing a new manufacturing facility, not to exceed $100,000, in
the event, subject to certain conditions, that the Merger is not consummated.
See "Technology Service Group, Inc.--Properties." Also, in the event the
Merger is not consummated, Elcotel will be obligated to issue a credit to TSG
for the difference between the purchase price of a certain product recently
purchased by TSG from Elcotel and the amount that TSG would have paid if TSG
had purchased a comparable product from another supplier. The total amount of
such credit would depend on the number of units purchased by TSG from Elcotel,
but Elcotel does not expect that the total amount of such credit will exceed
$100,000. Except as described above, all costs and expenses incurred in
connection with the Merger, the Merger Agreement and the transactions
contemplated thereby will be paid by the party incurring such costs or
expenses, whether or not the Merger is consummated. However, if the Merger is
consummated, Elcotel has agreed to issue 30,769 shares of Elcotel Common Stock
in payment of TSG's investment banking fee payable to Wexford Management.

Stockholders' Agreement to be entered into among Elcotel, Fundamental and
Wexford on the Closing Date. The following summary of the Fundamental/Wexford
Stockholders' Agreement contained in this Joint Proxy Statement-Prospectus is
not
 
                                      44
<PAGE>
 
intended to be a complete description of the terms and conditions thereof and
is qualified in its entirety by reference to the full text thereof. The
Fundamental/Wexford Stockholders' Agreement is filed as an exhibit to the
Registration Statement and is incorporated herein by reference.
 
RESTRICTIONS ON TRANSFERS
 
  Each of Wexford and Fundamental will not transfer any of the Elcotel capital
stock owned by it during the six month period beginning on the effective date
of the Merger; except that Fundamental may sell capital stock not to exceed
75,000 shares and Wexford may sell capital stock not to exceed 125,000 shares
(i) during the three-month period beginning on the day after the effective
date of the Merger and (ii) during the three-month period beginning three
months after the effective date of the Merger. Commencing on the date which is
six months after the effective date of the Merger, Wexford and Fundamental
may, subject to certain restrictions, transfer shares of capital stock owned
by them in accordance with applicable law. Notwithstanding the foregoing, (a)
Wexford may sell to A.T.T. IV, N.V. up to 142,857 shares (subject to
adjustment) of capital stock pursuant to a certain option agreement and (b)
Wexford or Fundamental may sell its capital stock to an affiliate.
 
TAG ALONG RIGHTS
 
  If Wexford or Fundamental (collectively the "Stockholders") proposes to sell
any shares of its capital stock otherwise permitted to be sold pursuant to the
terms of the Fundamental/Wexford Stockholders' Agreement, but excluding (i)
sales to certain affiliates or to A.T.T. IV, N.V. as described above or (ii)
any sale in which all of the Stockholders agree and are permitted to
participate, then such Stockholder must offer (the "Participation Offer") to
include in the proposed sale a number of shares of capital stock of the other
Stockholders, not to exceed the number of shares equal to the product of (A)
the aggregate number of shares of capital stock to be sold by such offering
Stockholder to the proposed transferee(s) and (B) a fraction the numerator of
which is equal to the number of shares of capital stock owned by such other
Stockholder and the denominator of which is equal to the number of shares of
capital stock held by all Stockholders. If any Stockholder has accepted the
Participation Offer, the offering Stockholder will reduce to the extent
necessary the amount of capital stock it otherwise would have sold in the
proposed sale so as to permit the other Stockholders who have accepted the
Participation Offer to sell the number of shares that they are entitled to
sell, and the offering Stockholder and such other Stockholders will sell the
number of shares specified in the Participation Offer in accordance with the
terms of such sale.
 
TERMINATION
 
  The Fundamental/Wexford Stockholders' Agreement will terminate as follows:
(i) upon the unanimous agreement of all Stockholders and Elcotel; (ii) upon
the happening of certain bankruptcy-related events with respect to Elcotel;
(iii) Elcotel is merged with or into another company and the stockholders of
Elcotel immediately prior to such merger do not own after such merger
substantially all of the capital stock of Elcotel or the surviving entity of
such merger in substantially the same proportions or whose shares of capital
stock will not be listed on a national securities exchange or quoted on the
National Association of Securities Dealers, Inc. Automated Quotation System;
or (iv) with respect to a specific Stockholder, at such time as such
Stockholder and certain related entities collectively own less than 5% of the
outstanding Elcotel Common Stock (but such Stockholder and its related
entities' registration rights pursuant to the Fundamental/Wexford
Stockholders' Agreement will only terminate upon such Stockholder and such
entities owning no outstanding Elcotel Common Stock). In any event, the
Fundamental/Wexford Stockholders' Agreement will terminate on the fifth
anniversary of the Closing Date of the Merger.
 
REGISTRATION RIGHTS
 
  Elcotel has agreed to file with the Commission, within forty-five days after
the effective date of the Merger, a "shelf" registration statement on Form S-3
or other appropriate available form, covering the Elcotel Common Stock issued
to Wexford pursuant to the Merger, any other Elcotel Common Stock beneficially
owned by
 
                                      45
<PAGE>
 
Wexford, any Elcotel Common Stock beneficially owned by Fundamental, any
Elcotel Common Stock beneficially owned by Acor S.A. and any other securities
issuable with respect to such Elcotel Common Stock by way of a stock dividend
or stock split or in connection with a combination of shares,
recapitalization, merger, consolidation, or reorganization (with certain
exceptions). Registration expenses are generally borne by Elcotel.
 
VOTING OF CAPITAL STOCK
 
  During the period ending immediately after the second annual meeting of
stockholders of Elcotel which occurs after the Elcotel Annual Meeting at which
the Merger is approved, each of the Stockholders has agreed that it will vote
(or cause to be voted) its shares of capital stock in favor of any nominees
for director nominated by the incumbent Elcotel Board.
 
                              LUCENT ACQUISITION
 
  On September 30, 1997, Elcotel acquired from Lucent Technologies Inc.
("Lucent") certain assets related to Lucent's payphone manufacturing and
component parts business (the "Lucent Acquisition"). The purchase price was
approximately $6.04 million, subject to adjustment based upon a final
inventory valuation. See "Unaudited Pro Forma Consolidated Financial
Information--Lucent Acquisition Purchase Price." Elcotel acquired from Lucent
the inventory, machinery, equipment, tooling and certain other assets related
to the payphone manufacturing and component parts business conducted by
Lucent, as well as a license of certain patent and other intellectual property
rights related thereto. Elcotel did not acquire any employees or facilities of
Lucent pursuant to such acquisition. As part of the acquisition, Elcotel is
expected to enter into a contract with a Taiwanese manufacturer that had been
Lucent's manufacturing source for its payphones. Elcotel borrowed $6,850,000
from its bank in connection with financing the Lucent Acquisition and the
purchase of certain capital equipment. The customers for Lucent's payphones
and component parts consisted principally of RBOCs and other telcos. Elcotel
believes that approximately 60% (approximately 1.2 million units) of the
current installed base of payphones in the United States are payphones of the
design purchased by Elcotel pursuant to the Lucent Acquisition. Elcotel
believes that a significant part of the revenues that may arise from the
assets acquired by Elcotel pursuant to the Lucent Acquisition will consist of
the sale of components and replacement parts with respect to that installed
base of payphones.
 
  Since 1995, Elcotel and Lucent had been involved in a strategic marketing
alliance primarily directed to international markets. In addition, Elcotel
produced and sold to Lucent a privately labeled Elcotel payphone using
Lucent's payphone housing and Elcotel's payphone network management system
which Lucent incorporated into its own payphone systems. Both companies
marketed that product in international markets.
 
  In addition, Lucent and Elcotel jointly marketed their respective products
in the United States, including the private labeled Elcotel payphone. As
indicated above, Elcotel believes there are approximately 1.2 million
payphones in operation in the United States of the design which was previously
sold by Lucent to RBOCs and other telcos. Elcotel believes that many of these
payphone units may require upgrades so that those payphones would internally
process more of the functions associated with the payphone rather than
performing those functions through a remote central office system. In
addition, Elcotel believes these payphone units will require continuing repair
and replacement of components, which had previously been supplied by Lucent.
 
  In January 1997, Lucent decided to cease its international business and
agreed to assign its customer contracts with respect to such international
business to Elcotel for completion of those orders, subject to the customer's
approval. With Elcotel's purchase of certain of Lucent's domestic payphone
assets, Elcotel believes that it will enhance its payphone opportunities in
the United States markets with RBOCs and other telcos. Elcotel believes that
if it is able to obtain most of the replacement parts and payphone housing
business from those customers to which Lucent previously sold, it could expect
annual revenues of approximately $12 million from that business. Elcotel also
believes that if it obtains such amount of business, Elcotel's overall
earnings will increase as a result. Elcotel believes that the Merger and the
Lucent Acquisition will allow it to reduce its levels of inventory, improve
manufacturing efficiencies, expand its sales to RBOCs and other telcos and
improve service to its customers.

refurbishment and upgrade conversion services to the telcos which consist of
the RBOCs and other local exchange carriers. See "Products and Services."
 
  TSG operates in one business segment as a provider of public communication
systems, products and services to communications providers in the United
States and foreign markets. TSG presently markets its products and services
primarily to the RBOCs in the United States and to cellular service providers
in certain international markets. TSG has derived substantially all of its
revenues from sales to four RBOCs. See "Sales and Markets." TSG is presently
developing a new microprocessor-based wireline payphone processor for
international markets and for the RBOC and independent markets in the United
States.
 
  The term "Predecessor" refers to TSG for all periods prior to October31,
1994, the date TSG Acquisition Corp., a wholly-owned subsidiary of Wexford,
acquired all of the outstanding capital stock of TSG (see "History--
Acquisition;" "TSG Management's Discussion and Analysis of TSG's Financial
Condition and Results of Operations" and "Consolidated Financial Statements of
Technology Service Group, Inc." included as Appendix C. TSG's principal
executive offices are located at 20 Mansell Court East, Suite 200, Roswell,
Georgia 30076, and its telephone number at that address is (770) 587-0208.
 
DEVELOPMENTS DURING FISCAL 1997
 
  Initial Public Offering. In May 1996, TSG completed the TSG IPO, an initial
public offering of 1,150,000 units (the "Units"), each Unit consisting of one
share of TSG Common Stock and one redeemable warrant ("Public Warrant"), at a
price of $9.00 per Unit for gross proceeds of $10,350,000. In connection with
such initial public offering, TSG issued, for nominal consideration, warrants
to the underwriter to purchase 100,000 shares of TSG Common Stock (the
"Underwriter Warrants"). Net proceeds from the offering, after underwriting
discounts and expenses of $1,231,897 and other expenses of $824,953, amounted
to $8,293,169. The net proceeds of the offering were used to repay TSG's then
outstanding indebtedness of $2,509,524 under bank term and installment notes;
to repay $3,808,589 of indebtedness outstanding under a bank revolving credit
agreement; and to repay $2.8 million of outstanding indebtedness under 10%
interest-bearing subordinated promissory notes payable to stockholders. See
"History--Acquisition;" "TSG Management's Discussion and Analysis of TSG's
Financial Condition and Results of Operations;" and "Consolidated Financial
Statements of Technology Service Group, Inc." included as Appendix C.
 
  Stock Purchase Agreement. TSG, Wexford, Acor S.A., Firlane Business Corp.
("Firlane"), and A.T.T. IV, N.V. ("ATTI") entered into a Stock Purchase and
Option Agreement on May 3, 1996 (the "Stock Purchase Agreement"). Wexford,
Acor S.A. and Firlane, concurrently with the TSG IPO, sold to ATTI an
aggregate of 366,300 shares of TSG Common Stock at a price of $8.14 per share
and options to purchase an additional 183,150 shares of TSG Common Stock at an
exercise price of $11.00 per share (the "Options") at a price of $.10 per
Option. Wexford sold 285,714 shares and Options to purchase 142,857 shares.
Acor S.A. sold 53,114 shares and Options to purchase 26,557 shares. Firlane
sold 27,472 shares and Options to purchase 13,736 shares. The consideration
received by Wexford, Acor S.A. and Firlane was $2,339,998, $435,004 and
$224,995, respectively. No consideration was received by TSG.
 
  Fiscal 1997 Facilities Consolidation. During the year ended March 28, 1997,
TSG closed its Kentucky facility and consolidated service operations into its
Virginia manufacturing facility. Also, during the year ended
 
                                      47
<PAGE>
 
March 28, 1997, TSG assigned the capital lease obligation related to the
closed facility to an unaffiliated third party, and recorded the retirement of
the outstanding capital lease obligation and the disposition of the property.
See "TSG Management's Discussion and Analysis of TSG's Financial Condition and
Results of Operations" and "Consolidated Financial Statements of Technology
Service Group, Inc." included as Appendix C.
 
  In November 1996, TSG executed a lease agreement with respect to a 39,200
square foot facility located in Alpharetta, Georgia that commenced on April 1,
1997. TSG originally planned to close its present corporate office facility
and to consolidate its product assembly operations and corporate activities
into the new facility. The lease has an initial term of five years and is
renewable for an additional five-year term. However, in view of the potential
business combination with Elcotel, TSG delayed the start-up of the new Georgia
facility. Elcotel and TSG have agreed, as part of their integration and
consolidation plan, to dispose of the facility and relocate certain TSG
assembly operations into Elcotel's facilities. On September 30, 1997, TSG
assigned the lease agreement to an unaffiliated third party. In contemplation
of an assignment of the lease and the Merger, TSG entered into an agreement
with Elcotel dated September 26, 1997 that provides for the assembly of
certain of TSG products by Elcotel at prices equal to TSG's cost. In the event
the Merger is not consummated, Elcotel has agreed, subject to certain
exceptions, to continue to assemble such products at prices equal to TSG's
cost until the first anniversary of the date Elcotel becomes obligated to
provide manufacturing services under the agreement, and has agreed to
reimburse TSG for certain costs in establishing a new manufacturing facility
to replace the Alpharetta facility not to exceed $100,000.
 
  Sales Agreements. In November 1996, TSG entered into a new non-exclusive
supply agreement, effective July 1, 1996, to provide its Gemini(TM) smart
payphones and processors, CoinNet payphone management system and other
payphone components to Telesector Resources Group, Inc., an affiliate of NYNEX
("NYNEX") for a period of five years. See "Sales and Markets--Domestic."
 
  In June 1997, TSG entered into an agreement with Southwestern Bell Telephone
Company ("SWB") that supersedes and terminates a December 1994 agreement
between the parties. Under the new agreement, TSG agreed (i) to reduce SWB's
remaining purchase commitment of GemStar(TM) processors and electronic locks
to approximately $3 million from approximately $8 million under the former
agreement and (ii) among other things, to upgrade SWB's payphone management
system. In return, SWB made a $250,000 cash payment to TSG, terminated TSG's
obligation to pay royalties on sales of GemStar processors to other customers
and terminated TSG's obligation to repay $375,000 received from the sale of
product software under the December 1994 agreement. SWB also agreed to make
additional cash payments to TSG aggregating up to $750,000 between July 2,
1997 and March 31, 1998, subject to TSG's compliance with the terms and
conditions contained in the agreement. See "Sales and Markets--Domestic." "TSG
Management's Discussion and Analysis of TSG's Financial Condition and Results
of Operations" and "Consolidated Financial Statements of Technology Service
Group, Inc." included as Appendix C.
 
HISTORY
 
  General. TSG was incorporated in the State of Delaware in 1975. Between 1975
and 1986, TSG was engaged in the high-speed dot matrix printer business. In
1986, TSG acquired International Teleservice Corporation, Inc., a company
engaged in the repair and refurbishment of telecommunication products
consisting of residential telephones and payphones. During 1987 and 1988, TSG
discontinued its high-speed dot-matrix printer business, sold the assets of
its residential telephone repair and refurbishment business, and began to
focus its business on the public communications industry. TSG established
International Service Technologies, Inc. ("IST"), which established a foreign
division in Taiwan, and Technology Service Enterprises, Inc., and expanded its
public communications business to include the manufacture and marketing of
payphones and payphone components and the provision of services to convert and
upgrade payphones with components designed and manufactured by TSG and its
subsidiaries. In 1991, Technology Service Enterprises, Inc. acquired the
assets of the Public Communication Systems Division of Executone Information
Systems, Inc. ("PCS"), including its microprocessor-based technology. In
fiscal 1993, TSG established Wireless Technologies, Inc. and began to develop
microprocessor-based wireless payphone products for international
applications. In April 1993,
 
                                      48
<PAGE>
 
International Teleservice Corporation, Inc., Technology Service Enterprises,
Inc. and Wireless Technologies, Inc. were merged into TSG.
 
  Acquisition. On October 31, 1994, TSG Acquisition Corp., a wholly-owned
subsidiary of Wexford, acquired all of the outstanding capital stock of TSG.
The consideration paid by TSG Acquisition Corp. aggregated $3.5 million. In
connection with this transaction, TSG entered into an Investment Agreement
with Wexford, Acor S.A. and Firlane. TSG issued an aggregate of 3.5 million
shares of TSG Common Stock at a price of $1.00 per share to Wexford. Wexford,
in turn, sold to Acor S.A. and Firlane 507,500 and 262,500 shares,
respectively, of TSG Common Stock. The consideration paid by Wexford, Acor
S.A. and Firlane for their shares of TSG Common Stock was $2,730,000, $507,500
and $262,500, respectively. Also, TSG borrowed $2.8 million from Wexford and
Acor S.A. and issued subordinated promissory notes due November 1, 1999 with
interest at a rate of 10% per annum (the "Affiliate Notes"). The Affiliate
Notes were repaid during the fiscal year ended March 28, 1997 with a portion
of the proceeds from the TSG IPO.
 
  Fiscal 1994 Restructuring. During the three years ended April 1, 1994, TSG
generated net losses due to poor operating performance caused in large part by
the termination of a sales agreement between TSG and one of its then
significant RBOC customers with respect to a first generation microprocessor-
based payphone product as a result of technical and delivery problems (which
were subsequently remedied) and the non-renewal of a refurbishment sales
agreement with that RBOC. In the fourth quarter of fiscal 1994, TSG initiated
a plan (the "fiscal 1994 Restructuring") to change certain senior management,
restructure its operations, refocus its development activities, increase sales
and attain profitable operations. Although TSG reduced its operating costs and
expenses, TSG continued to operate at a loss during the seven months ended
October 31, 1994 and five months ended March 31, 1995. However, during fiscal
1996 and fiscal 1997, TSG's sales performance improved and TSG returned to
profitability.
 
THE PUBLIC PAYPHONE INDUSTRY
 
  Domestic Market. Public telecommunication services, including "coin" or
"pay" telephone service, in the United States are provided by telcos (which
are regulated telephone operating companies), including those owned by the
RBOCs, AT&T and other long distance (or "inter-exchange") carriers ("IXCs")
and independent payphone providers. The operations of long distance and local
exchange carriers are subject to extensive regulation by the FCC and state
regulatory agencies (see "Government Regulation"). Virtually all services
offered by telcos and IXCs, including payphone services, are provided in
accordance with tariffs filed with appropriate regulatory agencies, including
the FCC. Independent payphone providers are subject to regulations of state
regulatory agencies.
 
  TSG believes that the RBOCs control approximately 60% (approximately 1.2
million units) of the payphones in service in the United States. The remaining
installed base of payphones are owned and operated by the large independent
telephone operating companies (such as GTE), other telcos and independent
payphone providers.
 
  The majority of payphones deployed by the RBOCs are essentially mechanical
devices that perform the functions of normal residential telephones, with the
additional ability to hold and collect or refund coins. In these conventional
payphone systems, all of the intelligence required to provide service is
located at central offices or other network locations of long distance
carriers or telcos and is supplied to the payphone via a "coin line." In June
1984, the FCC approved the operation of independently owned payphones, which
permitted independent payphone providers to enter the industry. However,
barriers to entry into the industry by independent payphone providers were
substantial. The RBOCs had in place and available the services of the central
offices to provide payphone service, including call rating and routing
information, the "bong" tone that signals callers to input calling card
numbers, and collection/return signaling for the payphone to collect or return
coins. These services were not required to be made available to independent
payphone providers and placed them at a disadvantage. Regulatory actions,
together with the development of technologically advanced microprocessor-based
payphones that perform the functions of the central office within the
telephone (referred to in the industry as "smart
 
                                      49
<PAGE>
 
payphones"), have enabled independent payphone operators to enter the industry
and compete effectively with the telcas. Microprocessor-based technology
provided independent payphone providers with the capability to route and
determine the proper charges ("rate") for calls and to deploy payphones
containing maintenance diagnostics and reporting features, coin administration
and credit card features, and station message detail recording and reporting
features. These features enable independent payphone providers to either route
calls to Alternate Operator Services or to store and retrieve call data and
billing information, thereby allowing the owner to share in the long-distance
revenues generated by the phone, reduce the cost of maintenance and
collection, and monitor coin pilferage, among other things.
 
  On February 8, 1996, the President of the United States signed into law the
Telecommunications Reform Act of 1996 (the "Telecommunications Act"), the most
comprehensive reform of communications law since the enactment of the
Communications Act of 1934. The Telecommunications Act eliminates long-
standing legal barriers separating telcos, long distance carriers, and cable
television companies and preempts conflicting state laws in an effort to
foster greater competition in all telecommunications market sectors, improve
the quality of services, and lower prices.
 
  The Telecommunications Act expressly supersedes the consent decree which led
to the break-up of AT&T, the formation of the RBOCs, and the line-of-business
restrictions that prohibited the RBOCs from providing long distance services
and from manufacturing telecommunications equipment. The RBOCs are now
permitted to provide long distance service outside their local service areas
and to seek approval from the FCC to provide long-distance service within
their local service areas based upon a showing that they have opened their
local exchange markets to competition. After the FCC has given its approval to
a request to provide in-region long distance service, an RBOC may also engage
in the manufacture and provision of telecommunications equipment and the
manufacture of customer premises equipment, including pay telephones. Such
manufacturing enterprises must be conducted through separate affiliates for at
least three years after the date of enactment of the Telecommunications Act.
In addition, a RBOC may not discriminate in favor of equipment produced or
supplied by an affiliate, but rather must make procurement decisions based on
an objective assessment of price, quality, delivery and other commercial
factors.
 
  TSG believes that as a result of the reform legislation, the public
communications industry will undergo fundamental changes, many of which may
affect TSG's business. The legislation is likely to increase the number of
providers of telecommunications services, including perhaps providers of
payphone services. This increase in the number of providers is likely to
stimulate demand for new payphone equipment. In that event, TSG believes that
existing payphone service providers, including the RBOCs, could seek to
enhance their technology base in order to compete more effectively with each
other and with new entrants. In addition, as the local exchange and intrastate
long distance markets are opened to competition, inter-exchange carriers
seeking to serve these markets may deploy greater numbers of payphones to
capture local and intrastate traffic. There can be no assurance, however, that
these trends will develop, or that if they do develop, they will have a
beneficial impact on the payphone market generally or on TSG's business in
particular. See "Government Regulation."
 
  Over the past couple of years, in response to the competitive pressures from
independent payphone providers and in anticipation of passage of the
Telecommunications Act, several of the RBOCs and other telcos began to upgrade
their payphone base with microprocessor-based "smart" payphone technology. TSG
believes that approximately 15% to 20% of the installed base of payphones
operated by the RBOCs have been upgraded with smart payphone systems,
including those provided by TSG. TSG's prospects for future and continued
profitability are largely dependent on such trend continuing. See "Sales and
Markets--Domestic."
 
  International Market. Internationally, it is estimated that there are
several million payphones in the installed base. Public communication services
in foreign countries are provided by large government-controlled postal,
telephone and telegraph companies ("PTTs"), former PTTs that have been
privatized for the purpose of investing in and expanding telecommunication
networks and services, and cellular carriers. TSG believes that a trend toward
privatization and liberalization of the international telecommunication
industry is opening the international markets, previously dominated by
monopoly and government infrastructure, to increased
 
                                      50
<PAGE>
 
competition. In addition, many countries are allowing private firms to
construct cellular networks and compete with national telecommunication
authorities. TSG believes that some of the large United States based
telecommunications companies, including certain RBOCs, have invested in
telecommunication opportunities abroad including the acquisition of interests
in the privatized PTTs and consortiums for the acquisition of licenses and
construction of cellular networks to provide cellular communication services.
On February 15, 1997, over 60 countries signed a World Trade Organization pact
aimed at opening the global telecommunications industry to competition. This
agreement provides for most of the countries to end their telephone monopolies
by the year 2000. However, the agreement, which must be ratified by the
individual countries, will likely encounter substantial opposition.
Accordingly, there is no assurance that the agreement will be ratified or
facilitate free market conditions within the global telecommunications market.
 
  Presently, the density of payphone installations in many foreign countries
on a per capita basis is far less than that in the United States. TSG believes
that many of these countries are seeking to expand and upgrade their
telecommunications systems and are funding programs to provide communication
services to the public. The expansion programs include the construction of
wireless networks, and TSG believes that wireless payphone service will become
one of the primary avenues of providing communication services to the public
in certain foreign markets. TSG believes that large scale payphone deployment
programs are underway in several foreign markets, and that the international
public communications industry will continue to evolve and be a significant
growth industry over the next several decades to the extent that privatization
and the investment in and expansion of both wireline and wireless networks
progresses.
 
  Although foreign markets are believed to be a potential source of
significant demand for TSG's products, there are impediments to TSG's ability
to penetrate such markets, including resource limitations, regulations and the
normal difficulties attendant on conducting international business.
 
PRODUCTS AND SERVICES
 
  TSG manufactures and markets "coin" and "coinless" "payphone" systems and
products that connect to and operate as integral parts of domestic and foreign
telecommunication networks. TSG also markets payphone and payphone component
repair, refurbishment and conversion upgrade services to local exchange
carriers in the United States. TSG's products include payphones equipped with
non-smart payphone electronics (for coin line installations) and payphones
equipped with microprocessor-based smart payphone processors (for coin line
and/or non-coin line installations) that connect to wireline telecommunication
networks ("wireline payphones") and payphones equipped with a specially
designed smart cellular processor that connect to cellular telecommunication
networks ("wireless payphones"). Smart payphone processors (and non-smart
electronics) are the primary electronic assemblies or "engines" of payphones.
TSG also supplies smart payphone retrofit kits and a wide range of payphone
components (including, among other things, dials, handsets, chrome doors,
credit card readers and volume amplification modules) required to manufacture
payphones and to repair and/or upgrade deployed payphones with enhanced
technology. TSG's smart payphone systems are provided with CoinNet payphone
management software. This management system is used by customers to remotely
manage networks of TSG's smart payphone products interactively. A significant
portion of TSG's revenues is derived from the sale of smart payphone
processors and payphone retrofit kits to certain RBOCs that are upgrading
their installed base of payphones with technologically advanced processors.
 
  TSG's wireline payphone products were developed specifically for the
regulated telephone operating companies in the United States. The design of
TSG's wireline coin payphones is based upon the Western Electric configuration
developed for use in the Bell system versus the GTE configuration developed
for the independent telephone companies and also used by most of the
independent payphone providers. TSG's coinless wireless ("cellular") payphone
products were developed for use in foreign markets, and are manufactured in
several different configurations, including the Western Electric
configuration, depending on the application.
 
  The majority of foreign countries follow the network standards of the
Consultative Committee for International Telephone and Telegraph ("CCITT").
One of the primary technical network differences in the
 
                                      51
<PAGE>
 
payphone industry between the countries following the CCITT network standards
and those following the U.S. network standards relates to call rating. TSG has
not to date offered a wireline product that operates with networks following
the CCITT standards. TSG is presently developing a new smart payphone
processor that it believes will be capable of operating with networks
following either standard. TSG believes that this technology will enable TSG
to compete in the independent market in the United States and in foreign
countries that follow the CCITT standard. TSG's new smart payphone processor
is currently undergoing limited field trial testing and evaluation in coin
line and in non-coin line installations domestically. TSG believes that its
new smart payphone processor will be available to market during the latter
part of its 1998 fiscal year, although there can be no assurance in that
regard. See "Design and Product Development."
 
  The following table outlines products currently offered by TSG:
 
 PRODUCT                   DESCRIPTION
 
 GEMINI SYSTEM II(TM)      The Gemini System II(TM) ("Gemini") product is a
                           sophisticated microprocessor-based smart payphone
                           processor which is programmable to operate in
                           either a coin line mode or a non-coin line mode.
                           The coin line mode uses the rating and answer
                           supervision services provided by the central office
                           ("CO") and associated network. In contrast, rating
                           and answer supervision services are performed
                           within the processor when programmed to operate in
                           the non-coin line mode. Programmable billing,
                           reporting and operating cost reduction features
                           offered with the Gemini product include: (i)
                           station message detail recording, which provides
                           for the storage of all call data within the phone;
                           (ii) maintenance reporting and diagnostics, which
                           provides for remote diagnosis of payphone and
                           component operating status via telemetry; (iii)
                           coin administration, which provides coin accounting
                           capability and reporting of coin box status; (iv)
                           call routing, which provides for the routing of
                           calls to the programmed carrier; and (v) credit
                           card billing and auditing, which provides the
                           ability to bill credit card calls and to identify
                           invalid cards or card numbers. The Gemini product
                           is also designed to interface with an electronic
                           lock to control and to permit remote monitoring of
                           collection activities. Programmable revenue
                           enhancement features offered with the Gemini
                           product include: (i) voice messaging, which enables
                           the user to record a message to the called party
                           rather than allow the call to go uncompleted; and
                           (ii) usage based pricing, which administrates local
                           call costing on the basis of time. The features
                           available with the Gemini product are designed to
                           enable customers to enhance revenues and to reduce
                           costs of operation and maintenance through accurate
                           scheduling of maintenance and collection
                           activities. All programming, retrieval, reporting
                           and telemetry features are performed remotely using
                           TSG's payphone software management system.
 
 GEMSTAR(TM)               The GemStar product is a microprocessor-based smart
                           payphone processor designed for coin line
                           applications which require the rating and answer
                           supervision functions performed by the CO network.
                           The GemStar product offers the primary cost
                           reduction and reporting features of the Gemini
                           product, including maintenance reporting and
                           diagnostics and coin administration. With added
                           memory, the GemStar product also provides station
                           message detail recording. The GemStar product is
                           also designed to interface with an electronic lock
                           to control and to permit remote monitoring of
                           collection activities.

  INMATE(TM)               The InMate product is a microprocessor-based smart
                           payphone processor designed for prisons where cost
                           reduction and revenue enhancement features as well
                           as other specialized features are required. The
                           InMate product offers station message detail
                           recording, maintenance reporting and diagnostics,
                           voice messaging, usage based pricing and call
                           routing. In addition, specialized features include:
                           (i) outgoing call restriction, which can restrict
                           calls to specified numbers; (ii) call duration,
                           which limits the time duration of calls; and (iii)
                           personal identification numbers, which permit valid
                           user access only. Coin administration features are
                           not provided in this coinless environment.
 
  GEMCELL(TM)              The GemCell product is a microprocessor-based
                           cellular payphone processor that interfaces to a
                           cellular transceiver for use in domestic and
                           international wireless networks. The GemCell
                           product was designed to have the primary features
                           available with the Gemini product except coin
                           administration. Instead, the GemCell product was
                           designed to accept debit ("prepay") cards, smart
                           ("chip") cards or credit cards as the form of
                           payment. The GemCell product is not currently
                           marketed in the U.S.
 
  COINNET(TM)              The CoinNet product is a remote payphone software
                           management system which operates on personal
                           computers in a multi-tasking environment. This
                           proprietary software product provides TSG's
                           customers with the ability to manage networks of
                           installed payphones interactively. Downloading
                           software changes, retrieving station message detail
                           recording data, maintenance and diagnostics data
                           and coin box data are a few of the functions of
                           this Unix or MS--DOS-based software system.
 
  PAYPHONES                TSG offers its payphones in a wide range of
                           electronic and smart configurations depending upon
                           the application requirements of its customers.
                           TSG's wireline payphones include coin (or token)
                           payphones and/or coinless payphones, including
                           credit card applications. TSG's wireless, coinless
                           payphones include debit ("prepay") and smart
                           (chip") card payphones which are offered in fixed
                           configurations as well as configurations for mobile
                           deployment, such as taxis, trains and buses. TSG's
                           smart wireline payphone technology derives power
                           from the telephone line, eliminating the need for
                           external power sources. TSG's wireless payphones
                           are powered by commercial electric line power or by
                           a solar powered platform so that they can be
                           deployed without network wiring and cabling.
 
  CELLULAR ASSISTANCE      TSG also offers a specialized Cellular Assistance
  PHONE                    Phone designed to provide emergency phone service
                           in specific applications, such as along highways
                           and in remote areas. The Cellular Assistance Phone
                           is provided with a cellular transceiver and is
                           powered by commercial electric line power or by a
                           solar powered platform so that it can be deployed
                           without network wiring and cabling. The features of
                           the Cellular Assistance Phone are limited to those
                           required for emergency situations and permit the
                           user to automatically dial a preset emergency
                           assistance number. The Cellular Assistance Phone is
                           not currently marketed in the United States.
 
 PAYPHONE COMPONENTS       Payphone components supplied by TSG include, among
                           others, non-smart payphone electronics, touchtone
                           dials, handsets, coin relays, and volume
                           amplification assemblies. These components are
                           manufactured at TSG's facilities to Bellcore
                           specifications.

 SERVICES                  TSG provides payphone and payphone component
                           repair, refurbishment and upgrade conversion
                           services for its customers. Refurbishment services
                           involve the rebuilding of payphone components and
                           sets to "like new" condition. Upgrade conversion
                           services include the modification of payphone
                           components and sets to an updated or enhanced
                           technology.
 
SALES AND MARKETS
 
  Domestic. TSG markets its payphone products and services predominately to
the RBOCs. In fiscal years 1995, 1996 and 1997, sales to RBOCs accounting for
greater than 10% of TSG's sales aggregated 72%, 88% and 90%, respectively, of
TSG's sales revenues. During fiscal 1995, Ameritech Services, Inc.
("Ameritech"), Bell Atlantic Corp. ("Bell Atlantic"), SWB and NYNEX accounted
for approximately $2.8 million, $5.8 million, $3.8 million and $2.2 million,
respectively, of TSG's sales. During fiscal 1996, Bell Atlantic, NYNEX and SWB
accounted for approximately $5.6 million, $7.9 million and $15.5 million,
respectively, of TSG's sales. During fiscal 1997, Ameritech, Bell Atlantic and
NYNEX accounted for approximately $4.6 million, $5.2 million and $20.2
million, respectively, of TSG's sales. TSG anticipates that it will continue
to derive most of its revenues from these customers, and other RBOCs, for the
foreseeable future. During the last year, mergers between Pacific Telesis Inc.
and SBC Communications, Inc. (the parent of SWB), and between Bell Atlantic
and NYNEX were announced and/or consummated. TSG cannot predict the impact
that these mergers will or may have on TSG's business.
 
  TSG competes for and enters into non-exclusive supply contracts to provide
products, components and services to the RBOCs. TSG has entered into sales
agreements to provide payphone components to Bell Atlantic, NYNEX and SWB. TSG
has entered into sales agreements to provide repair, refurbishment and
conversion services to Ameritech Services, Inc., Bell Atlantic, NYNEX and SWB.
These agreements have terms ranging from two to three years, are renewable at
the option of and subject to the procurement process of the particular RBOC,
contain fixed sales prices for TSG's products and services with limited
provisions for price increases, and expire at various dates from June 1997 to
March 1999. These sales agreements are frameworks for dealing on open account
and do not specify or commit TSG's customers to purchase a specific volume of
products or services. If orders are made, however, TSG has agreed to fill such
orders in accordance with the contract specifications. The agreements are
generally subject to termination at the option of the customer upon 30 days'
notice to TSG, or if TSG defaults under any material provision of the
agreement, including provisions with respect to performance.
 
  In November 1996, TSG entered into a non-exclusive sales agreement,
effective July 1, 1996, to provide its Gemini smart payphones and processors,
CoinNet payphone management system and other payphone components to NYNEX for
a period of five years. This agreement superseded a December 1995 smart
product sales agreement between TSG and NYNEX. The November 1996 agreement
sets forth the terms and conditions relating to the sale of products to NYNEX,
and does not specify or commit NYNEX to purchase a specific volume of products
from TSG. If orders are made, however, TSG has agreed to fill such orders in
accordance with NYNEX's specifications and at fixed prices set forth in the
agreement. TSG has agreed not to increase its prices during the term of the
agreement and has agreed to implement a continuous improvement program to
improve productivity and quality and to reduce product costs during the term
of the agreement. The agreement includes provisions for reductions in sales
prices to NYNEX based on product cost reductions achieved from the continuous
improvement program and based on NYNEX's purchase volume. The agreement
contains a "most favored customer" clause pursuant to which TSG has agreed to
provide price and other terms at least as favorable as those extended by TSG
to other customers for similar purchase volumes of products covered by the
agreement. TSG has agreed to indemnify NYNEX against expenses, liabilities,
claims and demands resulting from products covered by the agreement, including
those related to patent infringement and performance specifications. The
agreement may be terminated by either party upon default by the other party
upon 30 days' written notice, provided the default is not cured within 30 days
from the receipt of notice of default. Further, NYNEX may terminate the
agreement upon 120 days' written notice to TSG. However, upon such a
termination,
 
                                      54
<PAGE>
 
NYNEX has agreed to purchase TSG's inventories related to the products covered
by the agreement, provided that such obligation will not exceed the value of
NYNEX's purchases for a 120-day period, determined based upon the average
monthly volume for the previous six-month period, less the value of
outstanding orders to be shipped, the value of products which may be sold to
other customers, and the value of inventory that may be returned to TSG's
suppliers. The agreement expires on July 1, 2001.
 
  In June 1997, TSG entered into an agreement with SWB that supersedes and
terminates a December 1994 agreement between the parties. Under the new
agreement, TSG agreed to reduce SWB's remaining purchase commitment of GemStar
processors and electronic locks to approximately $3 million from approximately
$8 million under the former agreement and, among other things, upgrade SWB's
payphone management system. In return, SWB made a cash payment of $250,000 to
TSG, terminated TSG's obligation to pay royalties on sales of GemStar
processors to other customers and terminated TSG's obligation to repay
$375,000 received from the sale of product software under the December 1994
agreement. SWB also agreed to make additional cash payments of $250,000 on
July 2, 1997, $100,000 on September 1, 1997, $150,000 on December 31, 1997 and
$250,000 on March 31, 1998 to TSG subject to TSG's compliance with the terms
and conditions of the agreement, including conditions with respect to product
quality and performance, service and repair. As of the date hereof, TSG had
received scheduled payments from SWB in accordance with the terms of the
contract. SWB has the right to cancel the agreement without further obligation
to TSG, including any obligation to make additional payments or to purchase
additional products, upon a default by TSG of any of the terms and conditions
contained in the agreement. Further, SWB may terminate the agreement by giving
TSG 30 days' prior written notice, in which case, SWB is obligated to purchase
the products and make the payments set forth in the agreement. See "TSG
Management's Discussion and Analysis of TSG's Financial Condition and Results
of Operations" and "Consolidated Financial Statements of Technology Service
Group, Inc." included as Appendix C.
 
  TSG sells its products and services directly to its customers. TSG involves
a wide range of personnel in its sales and marketing activities, including its
Vice President of Sales and Marketing, two experienced sales directors, three
service technicians, its engineering staff, its quality managers, and its
President and CEO. TSG's engineering staff and service technicians provide
support and technical services via telephone without charge, and TSG provides
field engineering support services during the initial deployment of products
and when customers encounter unusual or technical problems. TSG's commitment
to service and support throughout its organization is directed at maintaining
strong relationships with customers' operating, technical and administrative
personnel. TSG also conducts training seminars and provides assistance to
customers in the installation and set-up of TSG's payphone software management
system.
 
  International. TSG markets its smart wireless payphones in Korea, Mexico,
Ecuador, Venezuela and other South American countries, primarily under
distributor and reseller relationships. TSG presently has distributor
relationships in Venezuela, for the South American markets, and in Korea. TSG
also markets its products in Central American markets directly and through an
independent sales representative.
 
  TSG's export sales during fiscal 1995, 1996 and 1997 approximated $1.4
million, $856,000 and $461,000, respectively. TSG's export sales during the
three months ended June 27, 1997 approximated $601,000. TSG believes that the
international public communications market represents a growth opportunity.
TSG, however, has limited experience exporting products and operating outside
the United States and there can be no assurance that TSG will be able to
generate significant revenues from international business. Conducting business
internationally is subject to a number of risks, including political
instability, foreign currency fluctuations, adverse movements in exchange
rates, economic instability, the imposition of tariffs and import and export
controls, changes in governmental policies (including U.S. policy toward
foreign countries), general credit and business risks and other factors, one
or more of which, if they occur, could have an adverse effect on TSG's ability
to generate international sales or operations. TSG's sales to date have been
denominated in U.S. dollars and as a result, no losses related to currency
fluctuations have been incurred. For the same reason, TSG has not engaged in
currency hedging activities. There is no assurance, however, that TSG will be
able to continue to
 
                                      55
<PAGE>
 
export its products in U.S. dollar denominations or that its business will not
become subject to significant exposure to foreign currency risks. In addition,
TSG intends to complete the development and begin marketing wireline payphone
products for international CCITT applications during fiscal 1998, and there is
no assurance that TSG will be able to successfully complete the development of
such products or that it will be able to successfully market such products.
Finally, many of TSG's known and potential international competitors have
substantially greater financial and other resources than TSG and, therefore,
are formidable competitors. See "Competition."
 
  TSG believes that wireless payphone services will become one of the primary
avenues of providing communication services to the public in many of the
developing nations in South America and Central America and that these markets
represent a significant growth opportunity. Many of the cellular licenses
awarded to companies in foreign markets to provide services in competition
with national communication authorities have been awarded to consortiums and
companies in which the RBOCs have invested. TSG believes that an opportunity
exists to expand its market channel within the RBOC arena by deployment of its
wireless payphone technology to international wireless concerns affiliated
with the RBOCs. TSG intends to continue to invest in the development of
wireless products and hardware for non-coin technologies including prepay and
debit cards, including smart ("chip") cards.
 
COMPETITION
 
  TSG believes that it is a significant provider of payphone products and
payphone repair services to the RBOCs. TSG operates in a highly competitive
environment and competes against numerous domestic and foreign providers of
payphones and payphone repair services that have financial, management and
technical resources substantially greater than those of TSG. In addition,
there are many other firms which have the resources and ability to develop and
market products which could compete with TSG's products. TSG believes its
ability to compete depends upon many factors within and outside its control,
including the timing and market acceptance of new products developed by TSG
and its competitors, performance, price, reliability and customer service and
support.
 
  The Telecommunications Act lifts the restriction on the manufacturing of
telecommunications equipment by the RBOCs. After the FCC finds that an RBOC
has opened its local exchange market to competition, the RBOC, through a
separate affiliate, may manufacture and provide telecommunications equipment
and may manufacture customer premises equipment, such as payphones. As a
result of the legislation, TSG could face new competitors in the manufacture
of payphones and payphone components from one or more of the RBOCs or their
affiliates. The RBOCs have financial, management and technical resources
substantially greater than TSG. However, the legislation does not permit RBOCs
to create joint manufacturing operations with each other. In addition, the
legislation provides that as long as Bellcore is an affiliate of more than one
RBOC, Bellcore may not engage in manufacturing telecommunications equipment or
customer premises equipment. The Telecommunications Act also incorporates
numerous safeguards to ensure that standards-setting organizations conduct
themselves fairly, and requires the FCC to establish a dispute resolution
process for equipment manufacturers involved in conflicts over standards
setting.
 
  TSG believes that the primary competitive factors affecting its business
with the RBOCs are quality, price, service and delivery performance. TSG
competes aggressively with respect to the pricing of its products and
services, and because TSG's contractual agreements with the RBOCs generally
provide TSG with limited ability to increase prices if manufacturing costs
increase, TSG attempts to reduce its manufacturing costs rather than increase
its prices. TSG also attempts to maintain inventory at levels which enable TSG
to provide immediate service and to fulfill the delivery requirements of its
customers.
 
  TSG believes that its principal competitors in the United States include
Protel Inc., Elcotel, Intellicall, Inc., Lucent Technologies and International
Totalizing Systems, Inc., and with respect to repair and refurbishment
services, Restor Industries, Inc. TSG also competes with numerous foreign
companies marketing products in the United States, including Northern Telecom,
Inc. However, TSG does not believe that foreign competitors have
 
                                      56
<PAGE>
 
yet been able to successfully penetrate the payphone industry in the United
States. Some of TSG's competitors, including Protel Inc., Intellicall, Inc.
and Elcotel, supply payphone products to independent payphone providers which
compete with the RBOCs. During fiscal 1997, TSG did not actively market its
products to independent payphone providers.
 
  Many of TSG's competitors are substantially larger than TSG and have
significantly greater financial, technical and marketing resources. As a
result, they may be able to respond more quickly to new or emerging
technologies and changes in customer requirements, or to devote greater
resources to the development, promotion and sale of their products than TSG.
It is also possible that new competitors may emerge and acquire significant
market share. Possible new competitors include large foreign corporations,
TSG's RBOC customers and other entities with substantial resources. Increased
competition is likely to result in price reductions, reduced gross margins and
loss of market share, any of which would have a material adverse effect on
TSG's business, results of operations and financial condition. There can be no
assurance that TSG will be able to compete successfully against current or
future competitors or that competitive pressures will not have a material
adverse effect on TSG's business, results of operations and financial
condition. In addition, it is unlikely that TSG will become a significant
supplier of smart payphone products to all of the RBOCs since competition for
business with the RBOCs is intense.
 
  Internationally, TSG competes with numerous foreign competitors, all of
which have financial, management and technical resources substantially greater
than TSG. These foreign competitors market payphone products predominately to
the PTT's and thereby dominate the international payphone market. TSG believes
that the primary competitive factors affecting its international business are
the ability to provide products that meet the specific application
requirements of the customers, quality and price.
 
  TSG expects that a number of personal communications technologies will
become increasingly competitive with payphone services provided by the
telephone companies and independent payphone providers. Such technologies
include radio-based paging services, cellular mobile telephone services and
personal communication services. However, TSG believes, but cannot assure,
that the payphone industry will continue to be a major provider of
telecommunications access.
 
  Prior to 1984, the regulated telephone companies held a monopoly in the
United States payphone market, and they continue to have a dominant share of
the payphone market. The regulated telephone companies have financial,
marketing, management and technical resources substantially greater than those
of private payphone providers. TSG believes that the regulated telephone
companies will continue to experience increasing competition from independent
payphone providers. Accordingly, TSG believes, but cannot ensure, that the
telephone operating companies can be expected to upgrade their technology base
and protect their market share.
 
MANUFACTURING, ASSEMBLY AND SOURCES OF SUPPLY
 
  TSG performs repair, refurbishment and conversion services and most of its
product assembly operations at its facilities. In addition, certain
components, including low-density electronic circuit board assemblies, dials
and handsets, are assembled at TSG's facilities. Other components are
purchased from various distributors and manufacturers, including contract
manufacturers engaged by TSG. TSG generally assembles its smart payphone
products from assemblies produced by manufacturers under contractual
arrangements.
 
  On October 21, 1994, TSG entered into a manufacturing agreement with Avex
Electronics, Inc. ("Avex"), a large contract manufacturer, that provided for
the production of TSG's GemStar circuit board assemblies and payphone
processor. TSG committed to purchase $12.2 million of GemStar assemblies. At
March 28, 1997, TSG had purchased the majority of its initial commitment. TSG
has also engaged Avex to manufacture the printed circuit board assemblies for
its Gemini processors, its new smart payphone processor presently under
development and other products, and has committed to purchase approximately
$5.5 million of assemblies for its new smart payphone processor during the
first year of production. The manufacturing agreement may be terminated by
either party for default upon a material breach of the terms of the agreement
by the other party,
 
                                      57
<PAGE>
 
provided such breach is not cured within a 30-day notice period. Further, TSG
may terminate the agreement at any time. However, upon a termination of the
agreement by TSG, TSG is obligated to purchase inventories held by the
manufacturer and pay vendor cancellation and restocking charges, and a
reasonable profit thereon. In addition, upon a cancellation by TSG of its
purchase obligation, or a substantial portion thereof, related to its new
smart payphone processor, TSG is obligated to pay a cancellation penalty of up
to $500,000. This cancellation obligation varies depending upon quantities
purchased by TSG and expires when TSG has substantially met its purchase
commitment. TSG is dependent upon Avex to manufacture and supply products
required to meet sales commitments under the terms of its smart product sales
agreements.
 
  On November 18, 1994, TSG entered into an exclusive dealer agreement with
Control Module, Inc. that provided TSG with the rights to purchase and supply
electronic lock devices to SWB in accordance with the terms of a December 1994
sales agreement between TSG and SWB. TSG committed to purchase approximately
$3.5 million of the electronic lock devices at specified prices over a two-
year period. At March 28, 1997, TSG had satisfied its purchase commitment, and
had an adequate inventory of electronic lock devices to meet its remaining
sales commitment to SWB. The dealer agreement expired upon TSG's purchase of
the committed volume.
 
  On September 16, 1991, TSG entered into a Manufacturing Rights Agreement
(the "Manufacturing Agreement") with Commtek Industries, Inc., an unaffiliated
Taiwan corporation. TSG granted Commtek the exclusive right to utilize the
assets owned by TSG's foreign division for a period of five years to
manufacture many of the non-electronic components and assemblies for TSG's
products. TSG agreed to purchase a minimum aggregate annual volume of $2.5
million during the first year of the agreement and $3 million for each year
thereafter. The Manufacturing Agreement expired on September 15, 1996.
However, the parties have continued the supply relationship under standard
purchase arrangements. TSG believes that there are alternative sources of
supply for the components and assemblies currently purchased from Commtek.
However, if a shortage or termination of the supply of any one or more of such
components or assemblies were to occur, TSG's business could be materially and
adversely affected.
 
WARRANTY AND SERVICE
 
  TSG provides warranties of 90 days with respect to repair, refurbishment and
conversion services and from one to three years on its products. Under TSG's
warranty program, TSG repairs or replaces defective parts and components at no
charge to its customers. TSG's contract manufacturers provide warranties on
the electronic circuit board assemblies ranging from 90 days to 120 days,
pursuant to which defective electronic circuit board assemblies are replaced
or repaired at no charge to TSG.
 
  TSG generally enters into repair agreements with respect to its smart
products under which TSG agrees to perform non-warranty repair services at
specified prices. TSG also provides repair, refurbishment and conversion
services under agreements with its customers. See "Sales and Markets."
 
LICENSES, PATENTS AND TRADEMARKS
 
  The engineering designs on which TSG's electronic products and components
are based were internally developed by TSG's engineering staff. TSG owns eight
United States patents relating to payphone components, its smart payphone
platform and other technology which expire between April 2010 and May 2014.
TSG has one patent application outstanding. Although TSG believes that its
patents and trademarks are important to its business, it does not believe that
patent protection or trademarks are critical to the operation or success of
its business. TSG does not believe that it is infringing on the patents of
others and would defend itself against any allegations to that effect. There
can be no assurance, however, that infringement claims will not be asserted in
the future or that the results of any patent-related litigation would not have
a material adverse affect on TSG's business.
 
  TSG regards its manufacturing processes and circuit designs as proprietary
trade secrets and confidential information. To protect this information, TSG
relies largely upon a combination of agreements with its contract
 
                                      58
<PAGE>
 
manufacturers, confidentiality procedures, and employee agreements. However,
there can be no assurance that TSG's trade secrets will not be disclosed or
misappropriated.
 
  TSG licenses certain technologies from third parties under agreements
providing for the payment of royalties. Royalty expense during the year ended
March 28, 1997 approximated $196,100. See "Consolidated Financial Statements
of Technology Service Group, Inc." included as Appendix C.
 
DESIGN AND PRODUCT DEVELOPMENT
 
  TSG's engineering department is staffed with software, electrical and
mechanical engineering professionals. Their activities are dedicated to the
development of new products, enhancements of TSG's deployed product line,
including the CoinNet management system, and enhancements to improve product
reliability. Their efforts are also directed to reducing product costs through
new manufacturing methods. During fiscal 1995 and 1996, TSG expended
approximately $938,000 and $1.2 million, respectively, on engineering,
research and development activities consisting primarily of the design and
development of GemStar, Gemini and GemCell products. During fiscal 1997, TSG
expanded its research and development activities for the purpose of designing
and developing a new smart payphone processor capable of operating in domestic
coin line installations, domestic non-coin line installations and in foreign
CCITT network installations. During the year ended March 28, 1997, TSG
expended approximately $1.8 million on engineering, research and development
activities, and in addition thereto, capitalized software development expenses
of $421,693.
 
  TSG believes that new products and product enhancements have the potential
to increase its market opportunities and are essential to its long-term
growth, particularly in international wireline markets, and TSG's ability to
fund future research and development activities, in turn, will be dependent
upon its ability to generate cash in excess of its operating needs. See "TSG
Management's Discussion and Analysis of TSG's Financial Condition and Results
of Operations."
 
EMPLOYEES
 
  At September 26, 1997, TSG had 148 full-time employees and 61 temporary
contract employees, consisting of 140 persons engaged in direct labor
activities, 32 persons engaged in manufacturing support activities, 16 persons
engaged in administrative, sales and finance activities and 21 persons engaged
in engineering and engineering support activities. In addition, TSG has three
independent contractors engaged in product development activities. TSG
considers its relations with its employees to be satisfactory.
 
  At September 26, 1997, none of TSG's employees were represented by a
collective bargaining unit.
 
BACKLOG
 
  The amount of TSG's backlog is subject to large fluctuations because TSG's
business depends upon a small number of customers and large orders. TSG
calculates its backlog by including only items for which there are purchase
orders with firm delivery schedules. Contractual commitments are not included
in backlog until purchase orders are received by TSG. At September 26, 1997,
the backlog of all products and services was approximately $3.8 million as
compared to approximately $5.3 million at September 27, 1996. TSG's objective
is to ship orders within 30 days of receipt and, therefore, TSG does not
expect its backlog, other than orders with scheduled deliveries under
contractual commitments, to exceed monthly sales levels. Accordingly, TSG's
backlog at any given date is not indicative of future revenues.
 
SEASONALITY
 
  TSG's sales are generally stronger during periods when weather does not
interfere with the maintenance and installation of payphone equipment by TSG's
customers. Accordingly, TSG's sales could be adversely affected during certain
periods of the year. TSG's sales may also be adversely impacted near the end
of the calendar year by the budget shortfalls of customers. As a result, TSG's
sales during its third quarter may decline significantly in relation to other
quarters.

POTENTIAL ENVIRONMENTAL LIABILITIES
 
  During the year ended March 28, 1997, TSG completed the evaluation,
assessment and monitoring of soil and groundwater contamination at one of
TSG's former facilities in Florida in accordance with requirements stipulated
by the Florida Department of Environmental Protection (the "FDEP"), and in
April 1997 received a formal "no further action status" notification for the
site from the FDEP. Accordingly, TSG has not accrued any additional costs with
respect to this site. It is possible, however, that the FDEP could reopen the
investigation in the future and require TSG to take further actions at the
site. TSG cannot estimate a range of costs, if any, that it could incur in the
future since such costs would be dependent upon the scope of additional
actions, if any, that may be required by the State of Florida.
 
  During the year ended March 28, 1997, TSG was a Potentially Responsible
Party ("PRP") for undertaking response actions at a facility for the
treatment, storage, and disposal of hazardous substances operated by Seaboard
Chemical Corporation from 1975 to 1989 at Jamestown, North Carolina. However,
TSG, as a small generator "De Minimis" party, executed a buy-out agreement
with respect to the remediation activities at a cost of approximately $8,200
during the year ended March 28, 1997. TSG believes, based on information
presently available to TSG, that it has no further obligations with respect to
the site. However, if additional waste is attributed to TSG, it is possible
that TSG could be liable for additional costs. TSG cannot estimate a range of
costs, if any, that it could incur in the future since such costs would be
dependent upon the amount of additional waste, if any, that could be
attributed to TSG.
 
  TSG has also been notified that it is a PRP with respect to response actions
at the Galaxy/Spectron Superfund Site in Elkton, Maryland. TSG, however, is
also a De Minimis party with respect to this site, and TSG believes its
proportionate share of costs to undertake response actions will likely be
insignificant. TSG has received notification that the De Minimis parties will
be able to buy out and obtain a release from any further clean-up liability at
the site at a cost presently estimated at $3.70 per gallon of contributed
waste, which would amount to $2,849 with respect to TSG's contribution. TSG
has not incurred any costs with respect to this site and believes that its
ultimate costs will not be material.
 
GOVERNMENT REGULATION
 
  TSG's operations are subject to certain federal, state and local regulatory
requirements relating to environmental, health and safety matters. Management
believes that TSG's business is operated in compliance with applicable
regulations promulgated by the Occupational Safety and Health Administration
and the Environmental Protection Agency and corresponding state agencies which
pertain to health and safety in the work place and the use, discharge and
storage of chemicals employed in its operations, respectively. Current costs
of compliance with such regulations are not material to TSG. However, the
adoption of new or modified requirements not presently anticipated could
create additional expense for TSG.
 
  The FCC regulates under Part 15 of its rules the operation and marketing of
devices which emit radio-frequency energy, whether intentionally or
unintentionally, and which do not require an individual license. The marketing
of such devices is also regulated under Part 2 of the FCC's rules. The FCC
regulates the direct connection of terminal equipment to the public switched
telephone network and the marketing of such equipment under Part 68 of its
rules. Parts 15 and 68 establish technical standards and procedural and
labeling requirements for equipment subject to these rules. Certain
modifications to equipment subject to these rules must also comply with these
technical standards and procedural and labeling requirements. Manufacturers of
products subject to Part 68 also must implement a continuing compliance
program under which products currently in production must be tested every six
months to ensure continued compliance with the applicable technical standards.
Certain types of devices sold as components or subassemblies are exempt from
the technical standards and procedural and labeling requirements of Parts 15
and 68. If such components or subassemblies are incorporated into and marketed
as part of systems or sets subject to Part 15 or Part 68, however, such
systems or sets must comply with the applicable rules. TSG believes that it
was in compliance with Parts 15 and 68 of the FCC's rules and regulations at
March 28, 1997.
 
 
                                      60

  TSG believes that the regulatory climate in the United States over recent
years has begun to influence the RBOCs' deployment of public communication
products. TSG also believes that the RBOCs have begun to upgrade their
payphone base with smart products that reduce their cost of management,
maintenance and coin administration and that include revenue enhancement
features. The deployment and business strategies of the public communication
divisions of the RBOCs have affected and will continue to affect TSG's
business. To the extent that these business strategies were to change, for
regulatory reasons or otherwise, TSG's prospects would be materially and
adversely affected.
 
  On September 20, 1996, the FCC released its order (the "Order") adopting
regulations to implement the section of the Telecommunications Act which
mandated fair compensation for all payphone providers and otherwise changed
the regulatory regime for the payphone industry pursuant to the
Telecommunications Act. The Telecommunications Act requires that the FCC
establish a per call compensation plan to ensure that all payphone service
providers are fairly compensated for each and every completed intrastate and
interstate call using their payphones. Among other matters, the Order
addressed compensation for non-coin calls, local coin calling rates, and
removal of subsidies and discrimination favoring payphones operated by telcos,
and authorized RBOCs and other providers to select service providers.
 
  In the Order, the FCC decided that the dial-around compensation rate for
access code calls and subscriber 800 and other toll free calls should be equal
to the deregulated local coin call rate. The FCC also established an interim
compensation plan whereby compensation for access code and subscriber 800
calls would be paid to payphone service providers. Under the first phase of
the FCC's interim compensation plan, payphone service providers would be
compensated at a flat rate of $45.85 per payphone per month (based on $.35 per
call multiplied by 131, the average number of 800 and access code calls per
payphone per month), as compared to the previous compensation of $6.00 per
month. This interim rate expired on September 1, 1997, and replaced all other
dial-around compensation prescribed at the state or federal level. This
compensation was to be paid by the major inter-exchange carriers based on
their share of toll revenues in the long distance market. Payphones owned by
the RBOCs and other telcos would be eligible for interim compensation when
they removed their payphones from their regulated accounts, which was to be
completed by April 15, 1997. By October 1, 1997, the inter-exchange carriers
were required to have per-call tracking instituted. At that point, under the
second phase of the interim compensation plan, all payphones would switch to a
per-call compensation rate set at $.35 per 800 or access code call. Under this
system, compensation would be paid on every completed 800-subscriber and
access code call. The carrier which is the primary beneficiary of the call
would pay the per-call compensation. After one year of deregulation of coin
rates (October 1, 1998), the compensation rate would be adjusted to equal the
local coin rate charge in a particular payphone.
 
  On July 1, 1997, the United States Court of Appeals for the District of
Columbia Circuit issued its decision on appeals of certain portions of the
Order. The Court ruled that the FCC was unjustified in setting the per-call
compensation rate at an amount equal to the deregulated local coin rate. The
Court remanded to the FCC for further consideration the issues of compensation
for 800 and access code calls both on a permanent and an interim basis. On
September 16, 1997, the Court clarified its earlier ruling by vacating the
compensation of $.35 per call on both an interim and default basis. The Court
ordered that interim compensation for 0+ calls be included in the new interim
compensation plan.
 
  The Court upheld the FCC's authority to regulate the rates charged for local
coin calls (thereby eliminating state limitations on such rates) and the FCC's
decision to require the carrier rather than the calling party to pay the
compensation to payphone service providers for 800 and access code calls.
 
  On October 9, 1997 the FCC issued an order addressing certain issues with
respect to payphone compensation previously remanded to it by the Court of
Appeals. The FCC set the per call compensation rate at $.284 per call during
the period October 7, 1997 through October 6, 1999. After that period, the
compensation rate would be whatever is charged at the phone for a local call,
less $.066, the amount the FCC determined to be the avoided cost in completing
a non-coin call. The FCC must still determine the compensation rate for the
period November 6, 1996 through October 6, 1997 and which carriers must pay
compensation for that period. It is likely that the FCC's latest action may
also be challenged in court. The ultimate outcome with respect to per call
 
                                      61
<PAGE>
 
compensation will have a significant impact on the business and operations of
payphone customers. Elimination or significant reductions in the amount, or
delay in the payment, of per call compensation may reduce demand for
payphones.
 
  The Order required telco payphones to be removed from regulation, separating
payphone costs from regulated accounts by April 15, 1997. This requirement is
intended to eliminate all subsidies that favor telco payphones. Telcos were
also required to reduce interstate access charges to reflect separation of
payphones from regulated accounts. In order to eliminate discrimination,
telcos are also required to offer coin line services to independent providers
if telcos continue to connect their payphones to central office-driven coin
line services. The FCC did not mandate unbundling of specific coin line
related services, but did make provisions to allow states to impose further
payphone services requirements that are consistent with the Order.
 
  The Order authorizes RBOCs to select the operator service provider serving
their payphones and for independent payphone providers to select the operator
service provider serving theirs. This provision preempts state regulations
that require independent providers to route intralata calls to the telcos. The
FCC, however, did not establish conditions that require operator service
providers to pay independent payphone providers the same commission levels as
the RBOCs demand.
 
  Although dramatic regulatory changes, particularly those created by recent
legislative actions, have occurred and may continue to occur, TSG believes
that the telecommunications industry will continue to be regulated in some
form by Federal and/or state authorities. There can be no assurance that
changes in regulations affecting the telecommunications industry would not
have an adverse impact on the operations of TSG's customers and, therefore, on
the operations of TSG.
 
PROPERTIES
 
  TSG's administration, sales, marketing and engineering activities have
historically been located at its headquarters in approximately 11,800 square
feet of leased office space located at 20 Mansell Court East, Suite 200,
Roswell, Georgia. The lease expires on December 31, 1997.
 
  In November 1996, TSG executed a lease agreement with respect to a 39,200
square foot facility located in Alpharetta, Georgia that commenced on April 1,
1997. TSG originally planned to close its present corporate office facility
and to consolidate its product assembly operations and corporate activities
into the new facility. The lease has an initial term of five years and is
renewable for an additional five-year term. However, in view of the potential
business combination with Elcotel, TSG delayed the start-up of the new Georgia
facility. Elcotel and TSG have agreed, as part of their integration and
consolidation plan, to dispose of the facility and relocate certain TSG
assembly operations into Elcotel's facilities. On September 23, 1997, TSG
assigned the lease agreement to an unaffiliated third party. In contemplation
of the assignment of the lease and the Merger, TSG entered into an agreement
with Elcotel dated September 26, 1997 that provides for the assembly of
certain of TSG products by Elcotel at prices equal to TSG's cost. In the event
the Merger is not consummated, Elcotel has agreed, subject to certain
exceptions, to continue to assemble such products at prices equal to TSG's
cost until the first anniversary of the date Elcotel becomes obligated to
provide manufacturing services under the agreement, and has agreed to
reimburse TSG for its costs in establishing a manufacturing facility to
replace the Alpharetta facility, not to exceed $100,000.
 
  TSG performs payphone assembly operations and repair, refurbishment and
conversion service operations in a 53,400 square-foot leased facility located
in Orange, Virginia. The Orange, Virginia facility is leased pursuant to the
terms of an operating lease agreement that expires on July 31, 1998, with the
right to renew the lease for four additional terms of one year each.
 
  During the third quarter of fiscal 1997, TSG closed a one hundred thousand
square-foot facility located in Paducah, Kentucky and consolidated service
operations into its Orange, Virginia facility.
 
  TSG believes its facilities are adequate for its business.

OVERVIEW
 
  TSG's operating performance subsequent to the fiscal year ended March 31,
1995 reflects the outcome of initiatives and plans begun during the later part
of fiscal 1994 and throughout fiscal 1995 to turn around the business, to
return to profitability, and to improve TSG's financial condition and
liquidity. These initiatives included a change in senior management, a
restructuring of the organization, and raising additional capital and
financing. The restructuring was also directed at reducing operating costs and
expenses and increasing sales and gross profit margins. In addition, TSG
refocused its engineering and product development activities to resolve
certain technical product problems experienced prior to the restructuring and
to develop new smart payphone products that would position TSG to capture a
significant share of the market for the technological upgrade of the installed
base of payphones owned by the RBOCs.
 
  This discussion contains certain forward looking statements concerning TSG's
operations, economic performance and financial condition. Such statements are
subject to various risks and uncertainties. Actual results could differ
materially from those currently anticipated due to a number of factors,
including those identified herein. See "Summary."
 
  All dollar amounts, other than per share data, stated in this TSG
Management's Discussion and Analysis of TSG's Financial Condition and Results
of Operations are stated in thousands.
 
BACKGROUND--THE ACQUISITION
 
  On October 31, 1994, TSG Acquisition Corp., a wholly-owned subsidiary of
Wexford, acquired all of the outstanding Capital Stock pursuant to an
Agreement and Plan of Merger dated October 11, 1994 between Wexford, TSG
Acquisition Corp., TSG and the majority holders of TSG's capital stock (the
"Acquisition"). The consideration paid by TSG Acquisition Corp. aggregated
$3,500 including contingent consideration of $330 consisting of cash of $230
and a subordinated note of TSG in the principal amount of $100, placed in
escrow and distributed to former stockholders in September 1995. The aggregate
consideration consisted of $3,004 to acquire the outstanding Capital Stock and
$496 to retire a $400 subordinated master promissory note payable to former
stockholders and related accrued interest and preference fees of $96.
Aggregate cash payments to former stockholders, including the contingent
consideration and the retirement of the subordinated master promissory note,
accrued interest and preference fees of $496, amounted to $3,222.
Consideration of $278 was withheld from amounts paid to former stockholders to
pay certain liabilities of TSG.
 
  The Acquisition was accounted for using the purchase method of accounting.
Accordingly, the aggregate purchase price of $3,170, exclusive of contingent
consideration, was pushed down and allocated to the net assets acquired based
upon their fair values. The excess of the purchase price over the estimated
fair value of the net assets acquired of $3,854 was recorded as goodwill. Upon
distribution of the escrow consideration in September 1995, the aggregate
purchase price was increased to $3,500 which increased the excess purchase
price over the estimated fair value of net assets acquired and recorded as
goodwill by $330. Prior to the Acquisition, TSG is sometimes referred to as
the "Predecessor."
 
  In conjunction with the Acquisition, TSG Acquisition Corp. was merged into
TSG. The outstanding shares of TSG Common Stock and TSG's preferred stock were
canceled and the outstanding shares of capital stock of TSG Acquisition Corp.
were exchanged for one share of TSG Common Stock, $.05 par value (the "merger
share"). In addition, on October 31, 1994, TSG amended its Certificate of
Incorporation to reflect authorized capital consisting of 10 million shares of
Common Stock, and 100,000 shares of preferred stock, $100 par value. Further,
TSG entered into an investment agreement with Wexford, Acor S.A. and Firlane,
referred to herein collectively as the "investors." Pursuant to that
investment agreement, TSG issued 3.5 million shares of TSG Common Stock in
exchange for the merger share. Also, TSG borrowed $2,800 from Wexford and Acor
S.A. and
 
                                      65
<PAGE>
 
issued 10% interest-bearing subordinated promissory notes in respect thereof
due November 1, 1999 (the "Affiliate Notes") to such persons.
 
  The accompanying analysis compares the results of operations of TSG for the
three months ended June 27, 1997 and June 28, 1996 and for the years ended
March 28, 1997 and March 29, 1996 and the results of operations of TSG for the
fiscal year ended March 29, 1996 and the combined results of operations of the
Predecessor and TSG for the fiscal year ended March 31, 1995.
 
  Because of the Acquisition, certain financial information described below is
not comparable in all respects. In addition, comparability is affected because
of the following purchase accounting adjustments made by TSG on October 31,
1994: (i) a net decrease in inventories of $45 consisting of a reduction of
$491 attributable to a change in the method used to estimate the amount of
manufacturing overhead included in inventories to a method based on labor
factors, not on a combination of labor and material factors, offset by an
increase in the basis of inventories of $446 to reflect their estimated net
realizable value; (ii) an increase in the basis of property and equipment of
$382 to reflect their estimated fair value; (iii) an increase in debt
obligations of $107 to reflect present values of amounts to be paid determined
at current interest rates; (iv) a net increase in accrued liabilities of $125
to reflect the acquisition expenses of TSG Acquisition Corp. to be paid by
TSG, offset by a reduction of accrued interest and preference fees of $96
retired in connection with the Acquisition; (v) a reduction in accrued
restructuring charges of $203 retired in connection with the Acquisition; (vi)
a reduction of notes payable to stockholders of $400 retired in connection
with the Acquisition; (vii) a net increase in other assets of $429 consisting
of an increase in identifiable intangible assets (consisting of product
software, patents, customer contracts, and unpatented technology) of $584 to
reflect their estimated fair values, offset by a reduction in goodwill and
deferred debt issuance expenses of $155 recorded by the Predecessor; and
(viii) an increase in goodwill related to the Acquisition of $3,854. The
principal impacts of the purchase accounting adjustments on TSG's results of
operations for the five months ended March 31, 1995 consisted of a slight
increase in depreciation due to the increase in the basis of property and
equipment and their estimated useful lives, an increase in amortization
expense of approximately $100 due to the net increase in the basis of
intangible assets, including goodwill, and their estimated useful lives, and
an increase in cost of goods sold of approximately $235 due to the revaluation
of inventories. The change in the method used to estimate the amount of
manufacturing overhead included in inventories did not have a significant
effect on TSG's results of operations for the five months ended March 31,
1995.
 
  During the fiscal years ended March 29, 1996 and March 28, 1997, TSG reduced
goodwill by approximately $653 in the aggregate with respect to the
realization of acquired deferred tax assets. During the three months ended
June 27, 1997, TSG reduced goodwill by approximately $82 with respect to the
realization of acquired deferred tax assets.

  Sales. The decrease in sales is primarily attributable to (i) a decrease in
sales volume of smart payphone systems and processors and (ii) a 25% reduction
in the sales price of Gemini(TM) processors under the terms of a sales
agreement between TSG and NYNEX entered into during the year ended March 28,
1997, offset by (i) an increase in exported wireless payphone systems of
approximately $600 and (ii) sales revenue of $625 under the terms of a new
sales agreement between TSG and SWB entered into in June 1997. Sales of smart
payphone products decreased by approximately $6,700 and accounted for
approximately 25% of sales during the three months ended June 27, 1997 as
compared to 69% of sales during the three months ended June 28, 1996.
Refurbishment and repair services and related product sales for the three
months ended June 27, 1997 decreased by approximately 10% as compared to the
same period in the prior year, and accounted for 55% of sales as compared to
31% in the prior year. No export sales were made during the three months ended
June 28, 1996.
 
  TSG believes that the uncertainty in the marketplace caused by the passage
of the Telecommunications Act adversely affected its sales. In addition,
following a high level of demand at the start of the program last year, NYNEX
stabilized its deployment of TSG's smart payphone systems and processors under
the five-year agreement entered into last year.
 
  In June 1997, TSG entered into an agreement with SWB that supersedes and
terminates a December 1994 agreement. Under the new agreement, TSG agreed to
reduce SWB's remaining purchase commitment of GemStar(TM) processor kits to
approximately $3,000 from approximately $8,000 under the former agreement. In
addition, TSG provided an upgraded electronic key product and, among other
things, agreed to provide equipment and software to upgrade SWB's payphone
management system. SWB made a $250 cash payment to TSG, terminated TSG's
obligation to pay royalties on sales of GemStar processors to other customers,
terminated a contingent obligation of TSG to repay revenue of $375 from the
sale of product software under the former agreement, and agreed to make
additional cash payments to TSG of $250 on July 2, 1997, $100 on September 1,
1997, $150 on December 31, 1997 and $250 on March 31, 1998, subject to TSG's
compliance with its obligations under the new agreement, including conditions
with respect to performance, service and repair.
 
  Cost of Goods Sold. Cost of goods sold as a percentage of sales increased to
82% for the three months ended June 27, 1997 as compared to 81% for the three
months ended June 28, 1996. This increase resulted principally from the
decrease in sales volume and sales prices referred to above and an increase in
manufacturing costs of printed circuit board assemblies shifted to contract
manufacturers, offset by the impact of the initial sales revenues recognized
under the terms of the new agreement between TSG and SWB.
 
  General and Administrative Expenses. The decline in general and
administrative expenses is primarily attributable to a reduction in expenses
of $50 from the closure of one of TSG's manufacturing facilities during the
year ended March 28, 1997, a decrease in accrued performance-based
compensation of $18 and a reduction in the provision for doubtful accounts
receivable of $31.
 
  Marketing and Selling Expenses. The decrease in marketing and selling
expenses during the three months ended June 27, 1997 as compared to the same
period in the prior year is primarily attributable to the expiration of a
royalty agreement and the resulting decrease in royalty expense associated
with sales of smart payphone products.
 
  Engineering, Research and Development Expenses. TSG began to expand its
engineering resources during the three months ended June 28, 1996 in order to
facilitate the development of a new smart payphone processor and the
implementation of lower-cost manufacturing methodologies. During the three
months ended June 27, 1997, the requirement for contract engineering services
diminished and the related expense decreased accordingly. Also, TSG
capitalized approximately $130 of software development costs in connection
with the development of its new smart payphone processor during the three
months ended June 27, 1997. Software development costs during the three months
ended June 28, 1996 were not significant.
 
  Litigation Settlement. Pursuant to the terms of a settlement agreement and
mutual release dated July 3, 1996, a suit filed against TSG by a former
supplier to collect approximately $400 of unpaid obligations was
 
                                      67
<PAGE>
 
dismissed with prejudice. As a result of the settlement agreement, TSG
realized a gain of $105 representing the difference between unpaid obligations
recorded in TSG's accounts and aggregate settlement payments set forth in the
settlement agreement.
 
  Interest Expense. The decrease in interest expense during the three months
ended June 27, 1997 as compared to the same period in the prior year is
primarily due to the repayment of outstanding bank and stockholder debt
obligations during May 1996 from proceeds of TSG's initial public offering.
See "Liquidity and Capital Resources--Cash Flows From Financing Activities."
 
  Income Taxes. During the three months ended June 27, 1997, TSG recorded an
income tax benefit of $12 on pre-tax income of $26 as compared to an income
tax provision of $217 on pre-tax income of $802 for the three months ended
June 28, 1996. Current tax benefits for the three months ended June 27, 1997
amounted to $287 as compared to current tax expense of $262 for the three
months ended June 28, 1996. Deferred tax expense for the three months ended
June 27, 1997 amounted to $275 as compared to deferred tax benefits of $45 for
the three months ended June 28, 1996.

  Overview. TSG's operations for the year ended March 28, 1997 reflect a
slowdown in sales during the last six months of the year which TSG attributes
to several factors as explained below, an increase in engineering, research
and development spending of $580 directed at the development of a new wireline
smart payphone product for the RBOC, independent and international markets, a
gain on the settlement of litigation of $105, restructuring charges of $63,
lower interest expense as a result of debt repayments from proceeds of an
initial public offering, and higher income taxes due to limitations on
utilization of net operating loss carryforwards.
 
  Sales. The increase in sales during fiscal 1997 as compared to fiscal 1996
is primarily related to volume fluctuations. Sales of smart payphone products
and components decreased by approximately $600 (3%) to $21,200 in fiscal 1997
as compared to $21,800 in fiscal 1996, and accounted for approximately 63% of
sales during fiscal 1997 as compared to 66% of sales during fiscal 1996. Sales
related to refurbishment, repair and conversion services and related products
during fiscal 1997 increased by approximately $1,200 (11%) to $11,800 as
compared to $10,600 in fiscal 1996, and accounted for 35% of sales as compared
to 32% in fiscal 1996. Export sales consisting primarily of wireless products
during fiscal 1997 approximated $461 as compared to approximately $856 during
fiscal 1996.
 
                                      68

  TSG believes that the reduction in smart product sales volume was
attributable to several key factors, including the uncertainties created by
merger activities among TSG's RBOC customers, the efforts of the RBOCs to
comply with the requirements of the Telecommunications Act during the last six
months of TSG's fiscal year, and related budget implications. Notwithstanding,
sales from refurbishment, repair and conversion services and related products
increased as a result of additional volume from one of TSG's customers that
has not begun a smart product upgrade conversion program. Export sales
activities during fiscal 1997 did not generate volume comparable to fiscal
1996, a trend TSG expects to reverse during the 1998 fiscal year.
 
  TSG believes, but cannot assure, that the decline in smart product sales
volume during the last six months of fiscal 1997, which is believed to be
attributable to efforts of the RBOCs to comply with the Telecommunications
Act, represents a short-term trend, and that its sales will be favorably
affected by the implications of the new law during fiscal 1998 and beyond.
 
  During fiscal 1997, TSG entered into a non-exclusive sales agreement,
effective July 1, 1996, to provide its Gemini smart payphones and processors,
CoinNet payphone management system and other payphone components to NYNEX for
a period of five years. Sales of smart payphone products during the year ended
March 28, 1997 were primarily attributable to shipments under a former sales
agreement between TSG and NYNEX executed in December 1995. This sales
agreement expired during the third quarter of fiscal 1997, and although TSG
entered into the new contract, no significant orders were received until
February 1997, which TSG believes was due to the factors enumerated above.
During the year ended March 29, 1996, a significant portion of TSG's sales
were attributable to shipments under the former NYNEX agreement as well as a
sales agreement between TSG and SWB executed in December 1994. SWB had
purchased approximately 65% of the committed volume under the agreement as of
March 29, 1996. However, sales to SWB under the 1994 contract were not
significant during TSG's 1997 fiscal year, a condition TSG believes is
attributable to a change in deployment strategies of SWB. In June 1997, TSG
entered into an agreement with SWB that supersedes and terminates the December
1994 agreement. Under the new agreement, TSG agreed to reduce SWB's remaining
purchase commitment to approximately $3,000 from approximately $8,000 under
the former agreement and, among other things, upgrade SWB's payphone
management system. In return, SWB made a $250 cash payment to TSG, terminated
TSG's obligation to pay royalties on sales of GemStar processors to other
customers, and terminated TSG's obligation to repay $375 received from the
sale of product software under the December 1994 agreement. SWB also agreed to
make additional cash payments to TSG of $250 on July 2, 1997, $100 on
September 1, 1997, $150 on December 31, 1997, and $250 on March 31, 1998,
subject to TSG's compliance with the terms and conditions of the agreement,
including conditions with respect to performance, service and repair. See
"Business--Sales and Markets" for a discussion of TSG's dependence on
significant customers and contractual relationships. Also, see "Liquidity and
Capital Resources--Operating Trends and Uncertainties."
 
  Cost of Goods Sold. The 2% increase in cost of goods sold is primarily
attributable to the increase in sales, the increase in the percentage of sales
related to refurbishment, repair and conversion services and related products,
and certain sales price reductions. Incremental costs of approximately $350
incurred in connection with the closure of one of TSG's manufacturing
facilities and the consolidation of service operations were offset
substantially by gains of approximately $273 from changes in estimates of
contingent liability obligations recorded in connection with the Acquisition.
Production costs as a percentage of sales increased to approximately 80%
during the year ended March 28, 1997 as compared to 79% during the year ended
March 29, 1996 due to these factors.
 
  General and Administrative Expenses. The 8% increase in general and
administrative expenses is primarily related to incremental costs and expenses
incurred as a public reporting entity after the consummation of TSG's initial
public offering in May 1996.
 
  Marketing and Selling Expenses. The 32% decrease in marketing and selling
expenses is primarily attributable to the expiration of a smart product
royalty agreement on June30, 1996 and the related decrease in royalty expense.
 
                                      69
<PAGE>
 
  Engineering, Research and Development Expenses. Engineering, research and
development expenses increased by 48%, primarily due to an expansion of
engineering resources and product development activities. TSG began to expand
its engineering resources during the first quarter of fiscal 1997 in order to
facilitate smart product development activities and the implementation of
lower-cost manufacturing methodologies. During the year ended March 28, 1997,
TSG capitalized approximately $422 of software development costs in connection
with the development of its new smart payphone processor.
 
  Litigation Settlement. Pursuant to the terms of a settlement agreement dated
July 3, 1996, a suit filed against TSG by a former supplier to collect
approximately $400 of unpaid obligations was dismissed with prejudice. As a
result of the settlement agreement, TSG realized a gain of $105 representing
the difference between the unpaid obligations recorded in TSG's accounts and
the aggregate settlement payments.
 
  Interest Expense. The 57% decrease in interest expense is primarily due to
the repayment of outstanding bank and stockholder debt obligations during May
1996 from proceeds of the TSG IPO. See "Liquidity and Capital Resources--Cash
Flows From Financing Activities."
 
  Restructuring Charges. During August 1996, TSG initiated a facilities
consolidation plan intended to augment its ongoing productivity and quality
improvement programs. The consolidation plan provided for the closure of TSG's
Kentucky manufacturing facility, the closure of TSG's Georgia corporate office
facility, the consolidation of repair, refurbishment and conversion service
operations into TSG's Virginia facility, and the consolidation of corporate
activities and product assembly operations into a new Georgia facility. In
connection with this plan, TSG recorded restructuring charges of $63 during
the year ended March 28, 1997. These restructuring charges consisted of
severance obligations and estimated losses related to the abandonment of
assets in connection with the closure of facilities.
 
  Other Income. TSG assigned the capital lease obligation related to its
former Kentucky facility to an unaffiliated third party, and recorded the
retirement of the outstanding capital lease obligation and the disposition of
the property during the fiscal year ended March 28, 1997. In connection with
this transaction, TSG realized a gain of $44 representing the difference
between the outstanding lease obligation ($933) plus the proceeds received
($50) and the net book value of the property ($939). The increase in other
income during the year ended March 28, 1997 as compared to the year ended
March 29, 1996 is primarily attributable to the gain from the disposition of
the facility and an increase in income related to the sublease of a portion of
property leased by TSG.
 
  Income Tax Expense. The 63% increase in income tax expense is primarily due
to a reduction in tax benefits from utilization of net operating loss
carryforwards. Benefits of net operating loss carryforwards used to offset
current tax expense amounted to $72 during fiscal 1997 as compared to $335
during fiscal 1996. Deferred tax benefits of $493 were recognized during the
year ended March 28, 1997 as compared to $50 during the year ended March 29,
1996. However, deferred tax benefits related to acquired deferred tax assets
aggregating $442 were applied to goodwill during fiscal 1997 as compared to
$211 during fiscal 1996.

  Overview. TSG's results for the year ended March 29, 1996 reflect a
significant increase in sales volume, an increase in operating expenses, and
an income tax provision of $326 on pre-tax profits of $1,503, as compared to
the previous year during which TSG reported a loss of $1,488. The results of
the Predecessor during the seven months ended October 30, 1994 includes a gain
from the recognition of a litigation settlement of $261, restructuring credits
of $534, and acquisition expenses of $166. The results of operations of TSG
for the five months ended March 31, 1995 include the effects of the
Acquisition, consisting primarily of amortization of intangible assets of
approximately $100 and an increase in cost of goods sold of approximately
$226. The results of TSG during fiscal 1996 include the effects of the
Acquisition, consisting primarily of amortization of intangible assets,
including goodwill, of $253 and an increase in cost of goods sold of
approximately $221.
 
  Sales. Sales of smart payphone products and components during fiscal 1996
approximated $21,800 as compared to approximately $6,600 during fiscal 1995.
Sales attributable to refurbishment and conversion services and related
payphone components approximated $10,600 during fiscal 1996 as compared to
approximately $12,300 during fiscal 1995. Sales of wireless payphone products
and components consisting primarily of export sales approximated $856 during
fiscal 1996 as compared to approximately $1,400 during fiscal 1995. The
$15,200 increase in sales of smart payphone products and components during
fiscal 1996 as compared to fiscal 1995 was primarily attributable to an
increase in sales volume of GemStar products, Gemini products and electronic
locks under sales agreements entered into in December 1994 and December 1995.
Sales increases attributable to GemStar, Gemini and electronic lock products
were offset by a reduction in sales volume of InMate products, which TSG
believes is primarily attributable to the saturation of the InMate institution
market. The 14% decline in sales from repair, refurbishment and conversion
services and related payphone components during fiscal 1996 as compared to
fiscal 1995 was primarily due to a reduction in volume that TSG believes was
attributable to implementation of smart product conversion programs by certain
customers, as well as competition. The decline in TSG's wireless product sales
during fiscal 1996 as compared to fiscal 1995 was primarily due to a decrease
in export volume to Mexico, which TSG believes was attributable to the
devaluation of the Mexican peso during fiscal 1995.
 
  Cost of Goods Sold. The increase in cost of goods sold is primarily
attributable to the 64% increase in sales during fiscal 1996 as compared to
fiscal 1995. Production costs as a percentage of sales declined to 79% during
fiscal 1996 as compared to 86% during fiscal 1995 as a result of the increase
in volume. In addition, during the five months ended March 31, 1995, TSG
accrued damages of $200 attributable to a product recall initiated in April
1995 (see "Operating Trends and Uncertainties"). Purchase adjustments from the
revaluation of inventories in connection with the Acquisition had the impact
of increasing cost of goods sold by $226 and $221 during the five months ended
March 31, 1995 and year ended March 29, 1996, respectively.
 
 
                                      71
<PAGE>
 
  General and Administrative Expenses. The decline in general and
administrative expenses is primarily related to cost reductions associated
with a restructuring initiated during the latter part of fiscal 1994 and
expenses of $166 incurred by the Predecessor during the seven months ended
October 30, 1994 in connection with the Acquisition. Amortization of goodwill
and other intangible assets recorded in connection with the Acquisition
approximated $253 during fiscal 1996 as compared to approximately $100 during
the five months ended March 31, 1995.
 
  Marketing and Selling Expenses. The increase in marketing and selling
expenses is primarily due to royalties on sales of GemStar and Gemini products
incurred under an asset purchase agreement dated January 11, 1991, and an
elimination of royalties during the first six months of fiscal 1995 pursuant
to a November 9, 1994 amendment to the royalty provisions of that agreement.
 
  Engineering, Research and Development Expenses. Engineering, research and
development expenses increased primarily due to an expansion of engineering
resources and product development activities, which had been reduced during
fiscal 1995 as a result of the restructuring initiated during the later part
of fiscal 1994.
 
  Restructuring Credits. During the five months ended March 31, 1995, TSG
settled severance obligations under employment contracts terminated in fiscal
1994 and negotiated the termination of certain non-cancelable lease
obligations with respect to facilities closed in connection with the
restructuring initiated at the end of fiscal 1994. The severance and lease
obligations were settled on terms more favorable than estimated during the
year ended April 1, 1994, which resulted in the recognition of restructuring
credits of $249 and $274, respectively, during the seven months ended October
30, 1994. Restructuring credits recognized during the seven months ended
October 30, 1994 aggregated $534.
 
  Litigation Settlement. During the seven months ended October 30, 1994, TSG
settled litigation against a supplier to recover costs and damages
attributable to defective components supplied to TSG, and realized a gain of
approximately $261, net of legal fees of $56.
 
  Income Tax Expense. During the year ended March 29, 1996, TSG generated a
taxable profit as compared to a net loss during the year ended March 31, 1995.
Benefits of net operating loss carryforwards used to offset current tax
expense during fiscal 1996 aggregated $335. Deferred tax benefits recognized
during fiscal 1996 of $50 were offset by benefits of acquired deferred tax
assets aggregating $211 that were used to reduce goodwill. There was no tax
provision during fiscal 1995 as a result of the reported net loss.
 
LIQUIDITY AND CAPITAL RESOURCES
 
 Initial Public Offering
 
  During May 1996, TSG completed the TSG IPO, an initial public offering of
1,150,000 Units, each Unit consisting of one share of TSG Common Stock and a
redeemable warrant, at a price of $9.00 per Unit for gross proceeds of
$10,350. In connection with the offering, TSG issued, for nominal
consideration, warrants to the underwriter to purchase 100,000 shares of TSG
Common Stock (the "Underwriter Warrants"). Net proceeds received by TSG as of
June 28, 1996 and March 28, 1997, after underwriting discounts and expenses of
$1,232 and other expenses of $808 and $824, respectively, aggregated $8,310
and $8,294, respectively. At March 29, 1996, TSG had incurred and deferred
offering expenses of $338. Accordingly, net proceeds from TSG's initial public
offering during the three months ended June 28, 1996 and year ended March 28,
1997 aggregated $8,648 and $8,632, respectively.
 
  The proceeds of the offering, net of underwriting discounts and expenses,
were initially used to repay then outstanding indebtedness consisting of
subordinated notes payable to stockholders of $2,800 and indebtedness under a
Loan and Security Agreement (the "Loan Agreement") between TSG and its bank
aggregating $6,318 (see "The Loan Agreement" and "Cash Flows From Financing
Activities"). Indebtedness outstanding under the Loan Agreement repaid with
the net proceeds consisted of a $2,200 term note due November 30, 1997, $310
outstanding under a $650 term note due November 30, 1997 and indebtedness
under a revolving credit line of $3,808.
 
                                      72
<PAGE>
 
 The Loan Agreement
 
  TSG is able to borrow up to a maximum of $9,000 under the terms of the Loan
Agreement between TSG and its bank. The Loan Agreement provides for revolving
credit indebtedness up to a maximum amount based on specified percentages
applied to the value of eligible collateral consisting of accounts receivable
and inventory less indebtedness, if any, under the $2,200 term note due
November 30, 1997. In addition, the Loan Agreement contains provisions for
certain term and installment indebtedness that was repaid with the proceeds of
TSG's initial public offering in May 1996. At March 29, 1996, March 28, 1997
and June 27, 1997, outstanding indebtedness under the Loan Agreement bore
interest at a variable rate per annum equal to 1.5% above a base rate quoted
by Citibank, N.A. The interest rate was reduced from 2% above a base rate
quoted by Citibank, N.A. on March 1, 1996. The base rate at March 29, 1996,
March 28, 1997 and June 27, 1997 was 8.25%, 8.5% and 8.5% per annum,
respectively. Amounts borrowed under the Loan Agreement are secured by
substantially all assets of TSG, including accounts receivable, inventories
and property and equipment. The Loan Agreement expires on November 30, 1997,
and is renewable annually for one-year periods unless terminated by the bank
upon the occurrence of an event of default or by TSG upon at least 90 days'
notice.
 
  Indebtedness under the Loan Agreement at March 29, 1996 consisted of $2,525
outstanding under term and installment notes, including the $2,200 term note
due November 30, 1997 and $325 outstanding under a $650 term note due November
30, 1997, and $1,094 outstanding under the revolving credit line. Indebtedness
under the Loan Agreement at March 28, 1997 and June 27, 1997 consisted of
$3,811 and $2,400, respectively, outstanding under the revolving credit line.
 
  The Loan Agreement contains conditions and covenants that prevent TSG from
engaging in certain transactions without the consent of the bank, including
merging or consolidating, payment of subordinated stockholder debt
obligations, declaration or payment of dividends, and disposition of assets,
among others. Additionally, the Loan Agreement requires TSG to comply with
specific financial covenants, including covenants with respect to cash flow,
working capital and net worth. Noncompliance with any of these conditions and
covenants or the occurrence of an event of default, if not waived or
corrected, could accelerate the maturity of the indebtedness outstanding under
the Loan Agreement. Although TSG was in compliance with the covenants set
forth in the Loan Agreement at June 27, 1997, there is no assurance that TSG
will be able to remain in compliance with such covenants in the future.
 
  TSG uses the financing available under the Loan Agreement to finance its
working capital requirements. If an event of default were to occur, however,
TSG's ability in this regard could be curtailed. In such event, TSG would seek
alternative financing sources, but there is no assurance that alternative
financing sources would be available on commercially reasonable terms, or at
all. Further, the Loan Agreement expires on November 30, 1997 unless it is
renewed in accordance with its terms. Elcotel intends to refinance with one
bank this indebtedness as Elcotel's indebtedness with its bank in connection
with consummation of the Merger. Although TSG believes that it will negotiate
an acceptable renewal or refinancing agreement if the Merger is not
consummated, there is no assurance that its efforts will be successful. TSG's
liquidity would be materially and adversely affected if it is unable to renew
or refinance its present credit facility.
 
  TSG borrows funds to finance increases in accounts receivable and
inventories and decreases in bank overdrafts, accounts payable and accrued
liability obligations to the extent that such requirements exceed cash
provided by operations, if any. TSG also uses the financing available under
the revolving credit line to fund operations, investing activities and
payments on long-term debt when necessary. TSG repays borrowed funds with
cash, if any, provided by operating activities. TSG measures its liquidity
based upon the amount of funds that TSG is able to borrow under the Loan
Agreement, which varies based upon operating performance and the value of
current assets and liabilities. At June 27, 1997, TSG had unused borrowing
availability of approximately $5,400 under the revolving credit facility based
on the value of eligible collateral.

 Cash Flows From Financing Activities
 
  Pursuant to the October 31, 1994 Investment Agreement entered into in
connection with the Acquisition, TSG borrowed $2,800 from Wexford and Acor
S.A. and issued 10% interest bearing subordinated promissory notes due
November 1, 1999. TSG issued a 10% interest bearing subordinated note to
Wexford in the principal amount of $2,361 dated October 31, 1994. TSG issued
10% interest bearing subordinated promissory notes to Acor S.A. in the
principal amount of $208 dated October 31, 1994, $100 dated October 31, 1994,
$83 dated November 10, 1994 and $48 dated December 23, 1994. During the year
ended March 28, 1997, TSG repaid these subordinated promissory notes from the
proceeds of its initial public offering.
 
  Concurrently with the Acquisition, the Loan Agreement was amended, and
$2,200 of debt outstanding under the revolving credit line was converted into
a term note payable on November 30, 1997. However, proceeds of $2,569 from the
subordinated promissory notes dated October 31, 1994 issued to Wexford and
Acor S.A. were used to retire debt outstanding under the revolving credit
line, and after such repayment, the initial principal balance outstanding
under the $2,200 term note on October 31, 1994 amounted to $1,292. Between
October 31, 1994 and March 31, 1995, TSG borrowed the balance available under
the $2,200 term note of $908, and also re-borrowed $970 under the revolving
credit line. During the year ended March 28, 1997, TSG repaid the $2,200 term
note from the proceeds of its initial public offering.
 
  Net payments of indebtedness under TSG's revolving credit line during the
seven months ended October 31, 1994 and five months ended March 31, 1995
amounted to $1,491 and $1,599, respectively. Net proceeds under the revolving
credit line during the year ended March 29, 1996 amounted to $124. Net
proceeds under TSG's revolving credit line during the year ended March 28,
1997 amounted to $2,717, net of the repayment of $3,808 from the proceeds of
TSG's initial public offering. Net payments under TSG's revolving credit line
during the three months ended June 27, 1997 and June 28, 1996 amounted to
$1,411 and $901, respectively.
 
  Principal payments on other long-term debt and capital lease obligations
during the seven months ended October 30, 1994, five months ended March 31,
1995 and year ended March 29, 1996 amounted to $459, $482 and $814,
respectively. Principal payments on other long-term debt and capital lease
obligations during the three months ended June 28, 1996 and year ended March
28, 1997 aggregated $2,578 and $2,600, including repayment of the $2,200 term
note due November 30, 1997 and repayment of $310 outstanding under the $650
term note due November 30, 1997 from the proceeds of TSG's initial public
offering. Principal payments on other long-term debt and capital lease
obligations during the year ended March 28, 1997, excluding the repayments of
term note indebtedness from the proceeds of the offering, amounted to $90. The
decrease in principal payments (exclusive of repayments made from proceeds of
the offering) for the year ended March 28, 1997 as compared to the year ended
March 29, 1996 is attributable to debt maturing during fiscal 1997, the
repayments made from the proceeds of the offering and the assignment of the
capital lease obligation related to TSG's Kentucky facility to an unrelated
third party in November 1996.
 
  TSG has also established a cash management program with its bank under which
TSG funds drafts as they clear the bank. Accordingly, TSG maintains bank
overdrafts representing outstanding drafts and utilizes the cash management
account as a source of funding. Bank overdrafts vary according to many
factors, including the volume of business, and the timing of purchases and
disbursements. During the seven months ended October 30, 1994, five months
ended March 31, 1995, year ended March 29, 1996 and three months ended June
28, 1996 and June 27, 1997, TSG's bank overdrafts increased by $324, $121,
$502, $760 and $82, respectively. During the year ended March 28, 1997, TSG's
bank overdrafts decreased by $760.
 
  In June 1996, TSG issued 40,000 shares of common stock for aggregate
proceeds of $160 upon the exercise of outstanding common stock purchase
warrants issued in May 1995. During the year ended March 28, 1997, TSG issued
5,000 shares of common stock upon the exercise of incentive stock options at
an aggregate exercise price of $5, and issued 6,760 shares of common stock
upon the exercise of rights granted under TSG's 1995 Employee Stock Purchase
Plan for an aggregate purchase price of $52.

 Cash Flows From Operating Activities
 
  During the seven months ended October 30, 1994, TSG generated $915 of cash
from operating activities. TSG used $99 of cash, net of non-cash charges and
credits of $324, to fund operating losses during the seven months ended
October 30, 1994. Because of recurring losses, TSG's cash resources during the
seven months ended October 30, 1994 were not sufficient to fund working
capital, capital expenditure and debt service requirements, and TSG was unable
to meet all of its accrued liability and supplier obligations as they became
due. However, TSG was able to generate cash from reductions in accounts
receivable and inventories of $578 and $1,388, respectively, and prepaid
expenses of $67 during the seven months ended October 30, 1994. The cash
provided from these asset reductions enabled TSG to begin efforts to decrease
its past due obligations, and during the seven months ended October 30, 1994,
$966 of cash was used to reduce accounts payable, accrued liabilities and
accrued restructuring charges.
 
  During the five months ended March 31, 1995, TSG used $1,598 of cash to fund
operating activities. Cash used to fund operating losses during the five
months ended March 31, 1995 amounted to $358, net of non-cash charges and
credits of $707. Also, because of an increase in the volume of business, TSG
used $330 and $764 of cash to fund increases in accounts receivable and
inventories, respectively, during the five months ended March 31, 1995. As a
result of the investor financing received in connection the Acquisition and an
increase in deferred revenue which provided $375 in cash (see "Capital
Commitments and Liquidity"), TSG was able to further pay down its past due
liability obligations, and used $618 of cash to reduce its accounts payable,
accrued liabilities and accrued restructuring charges during the five months
ended March 31, 1995.
 
  During the year ended March 29, 1996, TSG generated cash of $194 from
operating activities. Cash provided by operations, after adjustments related
to non-cash charges of $1,584, during the year ended March 29, 1996, amounted
to $2,761. Also, although TSG paid remaining undisputed past due liability
obligations, a net increase in TSG's supplier and accrued liability
obligations, income taxes payable, deferred revenue and accrued restructuring
charges provided cash of $2,599 during fiscal 1996. TSG used $4,634 in cash to
fund increases in accounts receivable and inventories of $1,206 and $3,428,
respectively. In addition, TSG expended $474 of cash to fund increases in
other assets including the acquisition of a patent license and the expenses of
TSG's initial public offering during the year ended March 29, 1996. The
increases in accounts receivable, inventories and current liability
obligations during the year ended March 29, 1996 were primarily related to the
increase in the volume of business as compared to fiscal 1995.
 
  Cash used to fund operating activities during the year ended March 28, 1997
amounted to $4,995. During the year ended March 28, 1997, TSG's operations
generated $2,613 in cash, after adjustments related to non-cash charges and
credits of $1,603. In addition, a decrease in accounts receivable caused by
sales fluctuations provided cash of $632 during the year ended March 28, 1997.
TSG used $2,485 in cash to fund an increase in inventories during the year
ended March 28, 1997. This inventory increase was related to the production of
electronic locks and GemStar products under contractual commitments, the
anticipated final production run of Gemini printed circuit board assemblies to
meet estimated sales requirements until the planned release of TSG's new smart
payphone processor and a slow-down of orders during the latter part of the
year (see "Results of Operations"). TSG used $419 of cash to fund changes in
prepaid expenses and other assets consisting primarily of capitalized software
development expenses. In addition, cash used for decreases in accounts payable
of $3,984, income taxes payable of $39, deferred revenue of $541 and accrued
liabilities, including accrued restructuring charges, of $771 aggregated
$5,335 during the year ended March 28, 1997. The decrease in accounts payable
is related to the slow-down in sales and TSG's efforts to reduce contracted
manufacturing volume and inventory balances during the latter part of fiscal
1997. During fiscal 1997, TSG satisfied its delivery requirements with respect
to revenues deferred at March 29, 1996 and deferred revenue decreased
accordingly. The decrease in accrued liability obligations is primarily
attributable to the expiration of a smart product royalty agreement and the
payment of remaining royalty obligations during fiscal 1997 and a decrease in
accrued interest due to the repayment of debt obligations.

  Cash provided by operating activities during the three months ended June 27,
1997 amounted to $1,398. During the three months ended June 27, 1997, TSG's
operations generated $600 in cash, after adjustments related to non-cash
charges and credits of $562. Changes in operating assets and liabilities
provided $798 of cash during the three months ended June 27, 1997. Inventories
decreased by $1,070 primarily as a result of shipments of smart payphone
products manufactured during the year ended March 28, 1997. Accounts payable
increased by $891 primarily as a result of fluctuations in inventory
purchases. The decrease in accrued liabilities of $306 and deferred revenue of
$375 is primarily attributable to satisfaction of obligations under the new
sales agreement between TSG and SWB, and the payment of performance based
compensation accrued at March 28, 1997. The increase in other assets is
attributable to the capitalization of software development costs of
approximately $130. The increase in refundable income taxes of $301 is
primarily attributable to current tax benefits recognized during the three
months ended June 27, 1997. Income taxes payable declined by $126 due to
payments made during the three months ended June 27, 1997.
 
  Cash used to fund operating activities during the three months ended June
28, 1996 amounted to $3,089. During the three months ended June 28, 1996,
TSG's operations generated $1,032 in cash, after adjustments related to non-
cash charges and credits of $447. Changes in operating assets and liabilities
used $4,121 of cash during the three months ended June 28, 1996. Accounts
receivable increased by $2,795 as a result of an increase in the volume of
business during the period. The increase in inventory of $1,203 and accounts
payable of $515, although partially related to the increase in the volume of
business, was primarily attributable to an excess of inventory purchases under
purchase commitments over sales requirements as a result of a change in the
delivery requirements of one of TSG's customers. During the three months ended
June 28, 1996, TSG satisfied the majority of its delivery requirements with
respect to prepayments from customers and deferred revenue decreased by $486.
The decrease in accrued liabilities of $341 was primarily attributable to the
payment of interest accrued under the terms of the subordinated notes payable
to stockholders that were retired during the period, and the payment of
performance based compensation accrued at the beginning of the period. Current
tax expense for the period exceeded estimated tax payments and income taxes
payable increased by $114.
 
 Cash Flows From Investing Activities
 
  Cash used to fund investing activities during the seven months ended October
30, 1994, five months ended March 31, 1995, years ended March 29, 1996 and
March 28, 1997 and three months ended June 27, 1997 and June 28, 1996 amounted
to $9, $60, $252, $363, $37 and $59, respectively. TSG's capital expenditures
during these periods consisted primarily of investments in manufacturing
tooling and equipment and automated test equipment. TSG expects that its
capital expenditures over the next several quarters will increase as TSG
continues to invest in manufacturing and test equipment required to improve
its in-house prototype and manufacturing capabilities and moves forward to
select and begin the implementation of new management information systems (see
"Capital Commitments and Liquidity").
 
 Capital Commitments and Liquidity
 
  TSG has not entered into any significant commitments for the purchase of
capital assets. However, TSG intends to purchase and install information
systems and capital equipment, including printed circuit board assembly
equipment and other manufacturing equipment, to advance its prototype
manufacturing and product testing capabilities during the next year. In
addition, TSG intends to expand its manufacturing capabilities through the
purchase of capital equipment in the future as required to meet the needs of
its business. However, there can be no assurance that capital expenditures
will be made as planned or that additional capital expenditures will not be
required. TSG believes, based on its current plans and assumptions relating to
its operations, that its sources of capital, including capital available under
the revolving credit line and cash flow from operations will be adequate to
satisfy its anticipated cash needs, including anticipated capital
expenditures, for at least the next year. However, in the event that TSG's
plans or the basis for its assumptions change or prove to be inaccurate, or
cash flow and sources of capital prove to be insufficient to provide for TSG's
cash requirements (due to unanticipated expenses, loss of sales revenues, a
significant increase in inventories, operating difficulties or otherwise), TSG
would be required to seek additional financing. In such an event, there can be
no assurance that additional financing would be available to TSG on
commercially reasonable terms, or at all.
 
                                      76

  Extension of credit to customers and inventory purchases represent the
principal working capital requirements of TSG. Significant increases in
accounts receivable and inventory balances could have an adverse effect on
TSG's liquidity. TSG's accounts receivable, less allowances for doubtful
accounts, at March 29, 1996, March 28, 1997 and June 27, 1997 amounted to
$3,866, $3,235 and $3,162, respectively. Accounts receivable at March 29,
1996, March 28, 1997 and June 27, 1997 consists primarily of amounts due from
the RBOCs. TSG's inventories, less allowances for potential losses due to
obsolescence and excess quantities, amounted to $8,659, $10,879 and $9,781 at
March 29, 1996, March 28, 1997 and June 27, 1997, respectively. The level of
inventory maintained by TSG is dependent on a number of factors, including
delivery requirements of customers, availability and lead-time of components
and the ability of TSG to estimate and plan the volume of its business. TSG
markets a wide range of services and products and the requirements of its
customers vary significantly from period to period. Accordingly, inventory
balances may vary significantly.
 
  The Loan Agreement between TSG and its bank limits outstanding revolving
credit indebtedness secured by eligible inventory to $3,100. Accordingly,
increases in inventory together with decreases in sales during the last nine
months has adversely affected TSG's liquidity under the revolving credit
agreement. The ability of TSG to improve its liquidity during the next year is
dependent on the level of smart payphone product orders and the extent of the
related inventory reduction, if any.
 
  In October 1994, TSG entered into a contract manufacturing agreement for the
production of its GemStar smart payphone processors. TSG committed to purchase
$12,200 of product over an eighteen-month period beginning in December 1994.
In addition, in November 1994, TSG entered into a dealer agreement that
committed TSG to purchase approximately $3,500 of electronic lock devices over
a two-year period. TSG initially scheduled purchases under these agreements
based on anticipated quantities required to meet its sales commitments. At
March 28, 1997 and June 27, 1997, TSG had acquired the majority of committed
purchase volume under these purchase agreements. However, as a result of a
decline in sales to SWB, TSG's inventories related to these agreements
increased by approximately $2,000 during the year ended March 28, 1997.
 
  During the three months ended June 27, 1997, TSG released orders under the
terms of the manufacturing agreement entered into in October 1994 to purchase
approximately $5,500 of assemblies for its new smart payphone processor. Upon
a termination of the agreement by TSG, TSG is obligated to purchase
inventories held by the manufacturer and pay vendor cancellation and
restocking charges, and a reasonable profit thereon. In addition, TSG is
obligated to pay a cancellation penalty of up to $500 if it cancels the $5,500
purchase obligation or a substantial portion thereof. The amount of the
cancellation penalty, if any, will vary depending upon quantities purchased by
TSG.
 
  In December 1994, TSG entered into a sales agreement with SWB under which
SWB committed to purchase $21,300 of GemStar smart processors, electronic
locks and other components over a three-year period. In connection with this
agreement, TSG sold the rights to certain product software for an aggregate
purchase price of $500. TSG received back an exclusive irrevocable perpetual
right to sub-license the software in connection with the sale of related
products. In return, TSG agreed to pay royalties on sales of licensed products
to other customers. At March 28, 1997, TSG was not obligated and had not paid
any royalties under the agreement. TSG was obligated to repay, three years
from the date of sale, a portion of the purchase price up to a maximum amount
of $375, which is reflected as deferred revenue in TSG's consolidated
financial statements at March 29, 1996 and March 28, 1997. However, in June
1997, TSG entered into an agreement with SWB that superseded and terminated
the December 1994 agreement. Under the new agreement, TSG agreed to reduce
SWB's remaining purchase commitment to approximately $3,000 from approximately
$8,000 under the former agreement and, among other things, upgrade SWB's
payphone management system. In return, SWB made a $250 cash payment to TSG,
terminated TSG's obligation to pay royalties on sales of licensed products to
other customers and terminated TSG's contingent obligation to repay revenue of
$375 received from the sale of product software under the December 1994
agreement. SWB also agreed to make additional cash payments to TSG of $250 on
July 2, 1997, $100 on September 1, 1997, $150 on December 31, 1997 and $250 on
March 31, 1998, subject to TSG's compliance with the terms and conditions of
the agreement, including conditions with respect to
 
                                      77
<PAGE>
 
performance, service and repair. SWB has the right to cancel the agreement
upon default by TSG. Therefore, there is no assurance that TSG will receive
the additional payments or that it will ship the products set forth in the
agreement. TSG has received all scheduled payments under the new agreement
which were due as of the date hereof.
 
 Operating Trends and Uncertainties
 
  Dependence on Customers and Contractual Relationships. During TSG's last
three fiscal years, four of the RBOCs have accounted for the majority of TSG's
sales. TSG anticipates that it will continue to derive most of its revenues
from such customers, and other telcos, for the foreseeable future. Significant
reductions and/or fluctuations in sales volume from these customers can have a
material adverse effect on TSG's business. In addition, the loss of a
significant customer could have a material adverse effect on TSG's business.
 
  TSG's prospects for continued profitability are largely dependent upon the
RBOCs upgrading the technological capabilities of their installed base of
payphones, and utilizing TSG's products and services for such upgrade
conversion programs. Also, TSG's prospects and the ability of TSG to maintain
a profitable level of operations are dependent upon its ability to continue to
secure contract awards from the RBOCs. In addition, TSG's prospects for growth
are dependent upon the market acceptance and success of its smart payphone
products, as well as development of smart products containing additional
advanced features. If TSG is unable to attract the interest of the RBOCs to
deploy TSG's smart payphone products, TSG's sales revenues, business and
prospects for growth would be adversely affected. Further, TSG's ability to
maintain and/or increase its sales is dependent upon its ability to compete
for and maintain satisfactory relationships with the RBOCs, particularly those
RBOCs that are presently significant customers of TSG.
 
  Prior to a restructuring instituted in 1994, TSG experienced difficulties
with a first generation smart payphone product, which difficulties
subsequently were remedied. Such difficulties, however, resulted in the
termination of a contract for such product with one of TSG's then significant
RBOC customers. There can be no assurances that similar difficulties will not
occur in the future.
 
  The assessment of penalties and/or damages under TSG's sales contracts could
have a material adverse effect on TSG's operating results and liquidity. In
April 1995, TSG initiated a recall of products due to contamination introduced
into the manufacturing process by TSG's contract manufacturer. Although TSG's
contract manufacturer was responsible for the repair or replacement of the
recalled product, TSG incurred liquidated damages under the terms of the sales
agreement with its customer in the amount of $200.
 
  Sales Prices. TSG's agreements with its contract manufacturers generally
provide that TSG will bear certain cost increases incurred by the
manufacturer. Accordingly, TSG's manufacturing costs may fluctuate based on
costs incurred by its contract manufacturers and such fluctuations could have
a material and adverse impact on earnings. TSG's sales agreements with
customers generally have fixed product prices with limited price escalation
provisions. Consequently, there is a risk that TSG may not be able to increase
sales prices when product costs increase. In the event TSG's costs increase
without a corresponding price increase or orders are lost due to price
increases, TSG's profitability would be adversely affected. TSG encounters
substantial competition with respect to smart payphone contract awards from
the RBOCs. Pending the release of TSG's new smart payphone processor later
this year, market pressures have eroded margins on the product version
currently being shipped. Until TSG releases its new smart payphone processor,
TSG will realize little to no gross profit with respect to smart product sales
to NYNEX. Any other price reductions in response to competition will also
result in reduced gross profit margins unless TSG is able to achieve
reductions in product costs.
 
  Seasonality. TSG's sales are generally stronger during periods when weather
does not interfere with the maintenance and installation of payphone equipment
by TSG's customers, and may be adversely impacted near the end of the calendar
year by the budget shortfalls of customers. However, TSG may also receive
large year-end orders from its customers for shipment in December depending
upon their budget positions. In the event TSG does not receive any significant
end of year orders for its smart payphone products, its third quarter sales
may decline significantly in relation to other quarters.
 
                                      78
<PAGE>
 
  Sources of Supply and Dependence on Contract Manufacturers. TSG generally
assembles its smart payphone products from assemblies produced by certain
manufacturers under contractual arrangements. To the extent that such
manufacturers encounter difficulties in their production processes that delay
shipment to TSG or that affect the quality of items supplied to TSG, TSG's
ability to perform its sales agreements or otherwise to meet supply schedules
with its customers can be adversely affected. In the event that contract
manufacturers delay shipments or supply defective materials to TSG, and such
delays or defects are material, TSG's customer relations could deteriorate and
its sales and operating results could be materially and adversely affected.
 
  As a percentage of revenues, the majority of TSG's products contain
components or assemblies that are purchased from single sources. TSG believes
that there are alternative sources of supply for most of the components and
assemblies currently purchased from those sources. Most of the components and
assemblies used by TSG for which there are not immediately available
alternative sources of supply are provided to TSG under standard purchase
arrangements. In addition, suppliers of certain electronic parts and
components to TSG and its contract manufacturers occasionally place their
customers on allocation for those parts. If a shortage or termination of the
supply of any one or more of such components or assemblies were to occur,
TSG's business could be materially and adversely affected. In such event, TSG
would be required to incur the costs associated with redesigning its products
to include available components or assemblies or otherwise obtain adequate
substitutes, and those costs could be material. Also, any delays in
redesigning products or obtaining substitute components could adversely affect
TSG's business.
 
  Telecommunications Act. As a result of the Telecommunications Act, the RBOCs
will be permitted to manufacture and provide telecommunications equipment and
to manufacture customer premises equipment when certain competitive conditions
have been met. It is possible that one or more RBOCs will decide to
manufacture payphone products, which would increase the competition faced by
TSG and could decrease demand for TSG's products by such RBOCs.
Notwithstanding, TSG believes that deregulation generally will benefit TSG.
However, there can be no assurance that TSG will benefit from deregulation or
that it will not be adversely affected by deregulation.
 
  Net Operating Loss Carryforwards. As of June 27, 1997, TSG had net operating
loss carryforwards for income tax purposes of approximately $11,000 to offset
future taxable income. Under Section 382 of the Internal Revenue Code of 1986,
as amended, the utilization of net operating loss carryforwards is limited
after an ownership change, as defined in such Section 382, to an annual amount
equal to the value of the loss corporation's outstanding stock immediately
before the date of the ownership change multiplied by the federal long-term
tax-exempt rate in effect during the month the ownership change occurred. Such
an ownership change occurred on October 31, 1994 and could occur in the
future. As a result, TSG will be subject to an annual limitation on the use of
its net operating losses of approximately $210. This limitation only affects
net operating losses incurred up to the ownership change and does not reduce
the total amount of net operating losses which may be taken, but limits the
amount which may be used in a particular year. Therefore, in the event TSG
maintains profitable operations, such limitation would have the effect of
increasing TSG's tax liability and reducing net income and available cash
resources if the taxable income during a year exceeded the allowable loss
carried forward to that year. In addition, because of such limitations, TSG
will be unable to use a significant portion of its net operating loss
carryforwards.

NEW ACCOUNTING PRONOUNCEMENTS
 
  In February 1997, the Financial Accounting Standards Board issued Statement
of Financial Accounting Standards No. 128, Earnings Per Share ("SFAS 128").
SFAS 128 requires disclosure of basic earnings per share based on income
available to common stockholders and the weighted average number of common
shares outstanding during the period, and diluted earnings per share based on
income available to common stockholders and the weighted average number of
common and dilutive potential common shares outstanding during the period. The
adoption of SFAS 128 is required for fiscal years ending after December 15,
1997, and earlier adoption is not permitted. Had TSG adopted SFAS 128 during
the years ended March 29, 1996 and March 28, 1997, basic earnings per share on
a pro forma basis would have been $.34 and $.22 per share, respectively and
diluted earnings per share on a pro forma basis would have been $.30 and $.21
per share, respectively.
 
  Also in February 1997, the Financial Accounting Standards Board issued
Statement of Financial Accounting Standards No. 129, Disclosure of Information
about Capital Structure ("SFAS 129"). SFAS 129 requires a company to explain
the privileges and rights of its various outstanding securities, the number of
shares issued upon conversion, exercise or satisfaction of required conditions
during the most recent annual fiscal period, liquidation preferences of
preferred stock and other matters with respect to preferred stock. Although
the statement is effective for periods ending after December 15, 1997, TSG's
financial statement disclosures are in compliance with SFAS 129.
 
  In June 1997, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 130, Reporting Comprehensive Income ("SFAS
130"). SFAS 130 establishes standards for reporting and display of
comprehensive income and its components in a full set of general-purpose
financial statements. Comprehensive income is defined as the change in equity
of a business during a period from transactions and events and circumstances
from non-owner sources, and includes all changes in equity during a period
except those resulting from investments by owners and distributions to owners.
SFAS 130 is effective for fiscal years beginning after December 15, 1997. The
adoption of SFAS 130 will not have a material effect on TSG's results of
operations or financial position.
 
  Also in June 1997, the Financial Accounting Standards Board issued Statement
of Financial Accounting Standards No. 131, Disclosures about Segments of an
Enterprise and Related Information ("SFAS 131"). SFAS 131 requires public
entities to report certain information about operating segments, their
products and services, the geographic areas in which they operate, and their
major customers, in complete financial statements and in condensed interim
financial statements issued to stockholders. SFAS 131 is effective for fiscal
years beginning after December 15, 1997. The adoption of SFAS 131 will not
have a material effect on TSG's results of operations or financial position.

(1) These options were granted at an exercise price equal to the per share
    market value of TSG Common Stock on the grant date and vest in four equal
    annual installments on the grant date and the first three anniversaries of
    the grant date. In the event of a change in control of TSG, 50% of the
    shares not then exercisable will become fully exercisable. This will occur
    if the Merger is consummated.
(2) The potential realizable value is calculated based on the term of the
    option (ten years) at its date of grant. It is calculated by assuming that
    the stock price on the date of grant appreciates at the indicated annual
    rate compounded annually for the entire term of the option; however, the
    optionee will not actually realize any benefit from the option unless the
    market value of TSG's stock price in fact increases over the option price.
 
AGGREGATED OPTION EXERCISES IN THE LAST FISCAL YEAR AND FISCAL YEAR-END OPTION
VALUES
 
  The following table sets forth for each of TSG's executive officers named in
the Summary Compensation Table, certain information regarding exercises of
stock options during the fiscal year ended March 28, 1997 and stock options
held at that date. The "Value of Unexercised In-the-Money Options at Fiscal
Year End" is based on the difference between the market price of the TSG
Common Stock subject to the option on March 28, 1997 ($5.25 per share) and the
option exercise (purchase) price per share. During fiscal 1997, there were no
option exercises by any of the executive officers named in the Summary

EMPLOYMENT CONTRACTS AND TERMINATION OF EMPLOYMENT AND CHANGE-IN-CONTROL
ARRANGEMENTS
 
  Mr. Bisceglia. On October 31, 1994, TSG and Mr. Bisceglia entered into an
employment agreement that expires on December 31, 1997, subject to certain
early termination provisions and automatic renewal provisions. Pursuant to the
agreement, Mr. Bisceglia serves as the President and Chief Executive Officer
and as a director of TSG and is paid an annual salary of at least $147,200.
His base salary is subject to annual review for merit and other increases at
the discretion of the TSG Board as of January 1, 1996 and each year
thereafter, and as a result of such reviews, Mr. Bisceglia's annual salary was
increased to $160,000 per year on January 1, 1997.
 
                                      87
<PAGE>
 
  Pursuant to the terms of the agreement, Mr. Bisceglia is entitled to the
same benefits made available to the other senior executives of TSG on the same
terms and conditions as such executives. The agreement provides that TSG will
reimburse and/or pay on Mr. Bisceglia's behalf up to $4,000 per month of
temporary living expenses, including travel to and from TSG and Mr.
Bisceglia's residence, until TSG requires Mr. Bisceglia to relocate, at TSG's
expense. Mr. Bisceglia is also entitled to receive an incentive bonus for each
fiscal year during the term of the agreement equal to 2% of the operating
profits of TSG, defined as net income before taxes, amortization and
depreciation, interest, gains and losses arising from revaluation of assets,
and charges or allocations by a parent or affiliated company except to the
extent that such charges are for expenses that directly relate to the
operations of TSG.
 
  Pursuant to the terms of this agreement, Mr. Bisceglia was granted an option
to purchase 150,000 shares of TSG Common Stock at an exercise price of $1.00
per share under TSG's 1994 Omnibus Stock Plan. The shares subject to the
option become exercisable in four equal annual installments commencing on the
date of grant. In the event TSG's majority shareholder, Wexford, ceases to own
at least 51% of TSG's outstanding voting stock, the option becomes exercisable
in full. Upon consummation of the Merger, the option will become exercisable
in full. The option expires ten years from the date of grant, unless earlier
terminated upon termination of Mr. Bisceglia's employment for cause or upon
Mr. Bisceglia's resignation. The agreement contains provisions that require
TSG, at the option of Mr. Bisceglia, to purchase unexercised option shares at
market value if Mr. Bisceglia's employment is terminated by TSG for reasons
other than cause. Otherwise, the option remains in effect until its expiration
date.
 
  If the agreement is terminated by TSG without cause, Mr. Bisceglia is
entitled to receive the amount of compensation and benefits he would otherwise
have received for the remaining term of the agreement or for six months,
whichever period is longer. The agreement is automatically renewed for
additional one-year periods unless TSG provides Mr. Bisceglia 180 days' notice
of non-renewal or Mr. Bisceglia provides TSG with 120 days' notice of
termination on December 31, 1997, or on any date thereafter.
 
  Pursuant to the agreement, Mr. Bisceglia is indemnified by TSG with respect
to claims made against him as a director, officer, and/or employee of TSG or
any subsidiary of TSG to the fullest extent permitted by TSG's Certificate of
Incorporation, its Bylaws and Delaware Law.
 
  Mr. Steadman. Mr. Steadman is employed by TSG pursuant to an agreement dated
October 31, 1994 at the rate of $5,000 per month plus $500 per day for each
day spent on TSG business outside of the New England area (in which Mr.
Steadman's office is located), but not to exceed $7,500 in any one month.
Pursuant to the agreement, Mr. Steadman is elected Chairman of the TSG Board
and in that capacity renders advice to the Board and management on business,
operational and financial matters. Mr. Steadman is entitled to participate in
employee benefit plans made available to other senior executives of TSG. The
agreement also provided for the grant to Mr. Steadman of an option to purchase
50,000 shares of TSG Common Stock at an exercise price of $1.00 per share. The
option has substantially the same terms as those of Mr. Bisceglia's option
described above.
 
  Other Officers. Effective July 1, 1996, TSG adopted a policy regarding all
officers of TSG, which is described under the heading "Report of the
Compensation Committee on Executive Compensation--Other Executive Officers."
 
  Notwithstanding anything to the contrary set forth in any of TSG's filings
under the 1933 Act or the 1934 Act that might incorporate future filings,
including any Annual Report on Form 10-K in whole or in part, the following
report of the Compensation Committee, and the Performance Graph, will not be
deemed to be incorporated by reference into any such filings.

REPORT OF THE COMPENSATION COMMITTEE ON EXECUTIVE COMPENSATION
 
  This report has been prepared by the Compensation Committee of the TSG Board
and addresses TSG's compensation policies with respect to the Chief Executive
Officer and executive officers of TSG in general for the fiscal year ended
March 28, 1997. Except for Mr. Steadman, each member of the Committee is a
non-employee director. Mr. Steadman's compensation is based on his employment
agreement, described above, which was approved by the TSG Board in November
1994.
 
 Compensation Policy
 
  The overall intent of the Committee in respect of executive officers is to
establish levels of compensation that provide appropriate incentives in order
to command high levels of individual performance and thereby increase the
value of TSG to its stockholders, and that are sufficiently competitive to
retain and attract the skills required for the success and profitability of
TSG. The principal components of executive compensation are salary, bonus and
stock options.
 
 Chief Executive Officer's Compensation
 
  The Chief Executive Officer's compensation for fiscal 1997 is based on a
written employment agreement that was negotiated and entered into between him
and TSG in October 1994 and is described above under the heading "Employment
Contracts and Termination of Employment and Change-in-Control Arrangements."
The salary in the agreement was determined to be appropriate by the members of
the Committee at the time the agreement was entered into based on the
financial and legal difficulties that TSG had experienced; the expertise and
responsibility that the position requires; the Chief Executive Officer's
experience with TSG in other capacities; and the subjective judgment of
Committee members of a reasonable compensation level. The increase in salary
granted by the Committee in January 1997 was based on Mr. Bisceglia's
performance during fiscal 1997 and that of TSG as a whole and the subjective
judgment of Committee members of a reasonable raise.
 
 Other Executive Officers
 
  Officers' Policy. Effective July 1, 1996, TSG adopted a policy regarding all
officers of TSG to acknowledge that they have extra duties and
responsibilities and that they are held to a higher standard of performance
than employees generally. The policy provides, among other things, for TSG-
paid life insurance for each officer in the amount of two and one-half times
base salary; long-term disability insurance coverage; the establishment of an
annual pool of funds from TSG's operating profits for the payment of bonuses;
severance benefits in the event the officer's employment is terminated without
cause consisting of a minimum of continued payment of two months' salary and a
maximum of four months' salary, plus the continuation of TSG benefits during
the period of continued salary payment; and the acceleration of one-half of
the officer's unvested option shares in the event of a sale of substantially
all of the assets of TSG or a person or entity acquires more than 51% of the
outstanding voting stock of TSG. This acceleration will occur if the Merger is
consummated. The policy also provides the same level of indemnity as for Mr.
Bisceglia, described above.
 
  Salary. During fiscal 1997, the salary of each executive officer other than
the salary of the Chairman and the Chief Executive Officer (described above
under the heading "Employment Contracts and Termination of Employment and
Change-in-Control Arrangements") was based on the level of his prior salary
and on the subjective judgment of members of the Committee as to what
constitutes a compensation level that is fair and calculated to retain the
executive in TSG's employ. In the case of one executive officer, his salary
increase was also based on a promotion to a new position with increased
responsibilities.
 
  Bonuses. In July 1996, pursuant to the Officers' Policy described above, the
Compensation Committee adopted a bonus plan for the 1997 fiscal year covering
officers which also covers key employees of TSG other than those covered under
a sales bonus plan of TSG. Bonuses under the plan are to be paid out of a pool
of funds equal to 15% of the net income of TSG (i) before taxes and before the
payment of any bonuses paid outside
 
                                      89
<PAGE>
 
of the plan (such as to the Chief Executive Officer pursuant to his employment
agreement) and (ii) after deducting an amount equal to 15% of stockholders'
equity. The allocation of the fund to individual officers and key employees is
based on the recommendations to the Compensation Committee of the Chairman and
Chief Executive Officer. The decision of the Compensation Committee is final
and is based the recommendations it receives and the subjective judgment of
members of the Committee. The bonus plan was renewed for the year ending April
3, 1998.
 
  Mr. Bartusek's incentive bonus compensation as Senior Vice President of
Sales and Marketing is based on the difference between TSG's quarterly
revenues in fiscal 1996 and the corresponding quarterly revenues in fiscal
1997. If 1997 quarterly revenues meet a minimum target established for each
quarter, he is paid a percentage of the difference. The plan was based on the
budgeted revenues for fiscal 1997 and the subjective judgment of the members
of the Committee as to the appropriate level of incentive payment if the
budgeted minimum quarterly revenues are achieved. Payment of the incentive
compensation is made only after TSG's year-end audit has been completed.
 
  In July 1997, a new incentive bonus compensation plan for Mr. Bartusek was
adopted for TSG's 1998 fiscal year. Mr. Bartusek's incentive bonus
compensation as Senior Vice President of Sales and Marketing will be based on
the difference between (i) TSG's quarterly revenues in fiscal 1998 and 80% of
targeted revenues for fiscal 1998 and (ii) TSG's annual gross profit margin
for fiscal 1998 and 80% of targeted gross profit margin for fiscal 1998. If
quarterly revenues for a quarter exceed 80% of targeted revenues for that
quarter, Mr. Bartusek will receive a bonus based on a percentage of the
excess. If annual gross profit exceeds 80% of targeted gross profit for the
year, Mr. Bartusek will receive a bonus based on a percentage of the excess to
the extent of attainment of quarterly objectives as evaluated by the
Committee. Bonuses based on quarterly revenues will be paid at the end of each
quarter. The bonus based on gross profit will be paid at the end of the fiscal
year.
 
  Stock Options. Stock options are granted by the Stock Plans Committee of the
TSG Board. The Stock Plans Committee believes that stock ownership by
executive officers is important in aligning management's and stockholders'
interests in the enhancement of stockholder value over the long term. For
options granted during fiscal 1997, the exercise price was equal to the market
price of the TSG Common Stock on the date of grant. The stock option grants
made to the executive officers in fiscal 1997 were made based on the
subjective judgment of the Committee members of the appropriate recognition
for their services to TSG during the 1997 fiscal year and prior years.
 
  Compliance with Internal Revenue Code Section 162(m). Section 162(m) of the
Internal Revenue Code (enacted in 1993) generally disallows a tax deduction to
public companies for compensation over $1million paid to its chief executive
officer and its four other most highly compensated executives. The
compensation payable by TSG to any one executive officer (including potential
income from outstanding stock options) is currently and for the foreseeable
future unlikely to reach that threshold. Qualifying, performance-based
compensation will not be subject to the deduction limit if certain
requirements are met. The Committee currently intends to structure stock
option grants to executive officers in a manner that complies with the
performance-based requirements of the statute.

DIRECTORS' COMPENSATION
 
  Directors who are employees of TSG receive no compensation, as such, for
services as members of the Board. Directors who are not employees of TSG
receive no cash compensation for their services as directors. Mr. Steadman,
who is an employee of TSG, receives compensation as such. See "Compensation
Committee Interlocks and Insider Participation." All directors are reimbursed
for their out-of-pocket business expenses incurred in attending Board meetings
and for performing any other services for TSG.
 
  Non-employee directors of TSG receive "formula" stock option grants under
TSG's 1995 Non-Employee Director Stock Option Plan approved by stockholders on
May 10, 1995. Each non-employee director serving on the date that TSG's
initial registration statement became effective (May 10, 1996) was
automatically granted an option to purchase 10,000 shares of TSG Common Stock
(the "Initial Grants") that became fully exercisable six months after the
grant date. After the Initial Grants, each non-employee director is
automatically granted an additional option to purchase 3,000 shares on each
anniversary of September 1, 1996 so long as he is then serving as a non-
employee director. Each non-employee director first elected to the TSG Board
after May 10, 1996 automatically receives an option to purchase 3,000 shares
of TSG Common Stock on the date of his or her election and, so long as he or
she is then serving as a non-employee director, an additional option to
purchase 3,000 shares of TSG Common Stock on each anniversary of that date.
All options under such Plan are granted at an exercise price per share equal
to the market value of a share of TSG Common Stock on the date of grant.
Except for the Initial Grants, all options vest in full on the first
anniversary of the grant date.
 
COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION
 
  Decisions concerning executive compensation (other than that of the
Chairman) are made by the Compensation Committee of the TSG Board, which
currently consists of Messrs. Davidson, Plaumann and Steadman. Mr. Steadman is
Chairman of the TSG Board and an employee of TSG; Messrs. Davidson and
Plaumann are neither officers nor employees of TSG or any of its subsidiaries.
During fiscal 1997, no executive officer of TSG served as a director or member
of a compensation committee of another entity with which any director of TSG
had any relationship as a director or officer, except that Mr. Steadman is
Chairman of the Board of Directors and a member of the Compensation Committee
of Wahlco Environmental Systems, Inc., of which Mr. Plaumann is a director and
former President.
 
  Mr. Steadman was elected Chairman of the TSG Board and is employed by TSG
pursuant to an employment agreement that is described under the heading
"Employment Contracts and Termination of Employment and Change-in-Control
Arrangements." In fiscal 1997, Mr. Steadman received compensation of $69,000,
plus the reimbursement of $11,003 of out-of-pocket expenses incurred in
rendering services to TSG, and was also granted a stock option to purchase
15,000 shares of TSG Common Stock at $5.00 per share.
 
  Pursuant to an acquisition in January 1991 of the assets of the Public
Communication Systems Division of Executive Information Systems, Inc. ("PCS"),
TSG was obligated to pay OAB, Inc. royalties of 3.5% of TSG's sales of
microprocessor-based components through June 30, 1996. Mr. Bartusek and
certain other employees of TSG, who were employees of PCS, are stockholders of
OAB. Royalty payments under this agreement during fiscal 1997 through the June
30, 1996 expiration date were approximately $420,100 (including payments of
accrued royalties at March 29, 1996 and debt payments on notes issued in
respect of accrued royalties), of which Mr. Bartusek received approximately
$80,000.
 
  Wexford and Acor S.A. are parties to an Investment Agreement pursuant to
which they acquired $2,361,082 and $438,918, respectively, of 10% subordinated
notes of TSG in 1994. In May 1996, TSG repaid the principal balances of these
notes in full--$2,361,082 to Wexford and $438,918 to Acor S.A. Interest paid
on the notes to Wexford and Acor S.A. during fiscal 1997 was $128,081 and
$23,810, respectively.

PERFORMANCE GRAPH
 
  The following graph assumes an investment of $100 on May 10, 1996 (the date
the TSG Common Stock was first registered under Section 12 of the 1934 Act)
and compares yearly changes thereafter (through March 28, 1997) in the market
price of the Common Stock with (i) the Nasdaq Market Index for U.S. Companies
(a broad market index) and (ii) the Nasdaq Telecommunications Index, a
published industry index.
 
  The performance of the indices is shown on a total return (dividend
reinvestment) basis; however, TSG paid no dividends during the period shown.
The graph lines merely connect the beginning and end of the measuring periods
and do not reflect fluctuations between those dates.

Interlocks and Insider Participation" in "Executive Compensation," above.
 
            UNAUDITED PRO FORMA CONSOLIDATED FINANCIAL INFORMATION
 
  THE UNAUDITED PRO FORMA CONSOLIDATED FINANCIAL INFORMATION IS PRESENTED FOR
INFORMATIONAL PURPOSES ONLY AND IS NOT NECESSARILY INDICATIVE OF THE OPERATING
RESULTS OR FINANCIAL POSITION THAT WOULD HAVE OCCURRED, NOR IS IT NECESSARILY
INDICATIVE OF THE FUTURE OPERATING RESULTS OR FINANCIAL POSITION OF ELCOTEL
FOLLOWING THE MERGER OR THE LUCENT ACQUISITION.
 
  The following tables set forth certain unaudited pro forma consolidated
financial information of Elcotel after giving effect to the Merger and the
Lucent Acquisition. The unaudited pro forma consolidated balance sheet set
forth below was prepared as if the Merger and the Lucent Acquisition had been
consummated on June 30, 1997. The unaudited pro forma consolidated statements
of operations for the year ended March 31, 1997 and three months ended June
30, 1997 set forth below were prepared as if the Merger and the Lucent
Acquisition had been consummated on April 1, 1996.
 
  The unaudited pro forma financial information presented below has been
prepared assuming the Merger and the Lucent Acquisition are accounted for
using the purchase method of accounting. Accordingly, the unaudited pro forma
consolidated balance sheet assumes that (1) the Merger consideration,
consisting of (i) the fair value of securities to be issued by Elcotel to
effect the Merger, (ii) the fair value of outstanding common stock, options
and warrants of TSG to be converted into Elcotel securities, and (iii) the
estimated direct costs and expenses to be incurred by Elcotel in connection
with the transaction, is allocated to the assets and liabilities of TSG based
on their estimated fair values and (2) the aggregate purchase price related to
the Lucent Acquisition is allocated to the assets acquired based on their
estimated fair values.
 
  The unaudited pro forma consolidated financial information presented below
reflects pro forma adjustments that are directly attributable to the Merger
and the Lucent Acquisition and the use of the purchase method of accounting.
The accompanying unaudited pro forma consolidated statements of operations do
not reflect anticipated cost reductions or revenue enhancements expected to be
realized from the Merger or the anticipated revenues, gross profit and
operating expenses from the Lucent Acquisition. Accordingly, the unaudited pro
forma consolidated statements of operations for the year ended March 31, 1997
and three months ended June 30, 1997 are not necessarily indicative of the
consolidated results of operations as they might have been had the Merger and
Lucent Acquisition actually occurred on the dates indicated, nor are they
necessarily indicative of future results.

                             FINANCIAL INFORMATION
                 (DOLLARS IN THOUSANDS EXCEPT PER SHARE DATA)
 
BASIS OF PRESENTATION
 
  The accompanying unaudited pro forma consolidated financial information is
derived from and should be read in conjunction with the historical
consolidated financial statements and the related notes thereto of Elcotel and
TSG appearing elsewhere in this Joint Proxy Statement-Prospectus or
incorporated by reference herein.
 
  The unaudited pro forma consolidated balance sheet was prepared as if the
Merger and the Lucent Acquisition had been consummated on June 30, 1997. The
unaudited pro forma consolidated statements of operations for the year ended
March 31, 1997 and three months ended June 30, 1997 were prepared as if the
Merger and the Lucent Acquisition had been consummated on April 1, 1996.
 
  The unaudited pro forma consolidated financial information has been prepared
assuming the Merger and the Lucent Acquisition are accounted for using the
purchase method of accounting. Accordingly, the accompanying unaudited pro
forma consolidated balance sheet assumes that (1) the Merger consideration,
consisting of (i) the fair value of securities to be issued by Elcotel to
effect the Merger, (ii) the fair value of outstanding common stock, options
and warrants of TSG to be converted into Elcotel securities and (iii) the
estimated direct costs and expenses to be incurred by Elcotel in connection
with the transaction (collectively, the "merger consideration" or the
"purchase price"), is allocated to the assets and liabilities of TSG based on
their estimated fair values and (2) the aggregate purchase price related to
the Lucent Acquisition is allocated to the assets acquired based on their
estimated fair values.
 
  The unaudited pro forma consolidated financial information reflects pro
forma adjustments that are directly attributable to the Merger and the Lucent
Acquisition and the use of the purchase method of accounting. The accompanying
unaudited pro forma consolidated statements of operations do not reflect
anticipated cost reductions or revenue enhancements expected to be realized
from the Merger or the anticipated revenues, gross profit and operating
expenses from the Lucent Acquisition. Accordingly, the unaudited pro forma
consolidated statements of operations for the year ended March 31, 1997 and
three months ended June 30, 1997 are not necessarily indicative of the
consolidated results of operations as they might have been had the Merger and
Lucent Acquisition actually occurred on the dates indicated, nor are they
necessarily indicative of future results.
 
MERGER CONSIDERATION
 
  The Merger consideration has been estimated based on the terms of the Merger
Agreement and assuming the Merger had been consummated on June 30, 1997. The
estimated merger consideration is summarized as follows:

</TABLE>
 
  The average closing market price of Elcotel Common Stock for a period of
four days before and after the terms of the Merger were announced to the
public of $6.50 per share has been used to determine the fair value of the
shares of Elcotel Common Stock to be issued by Elcotel in connection with the
Merger.

  At June 30, 1997, there were outstanding warrants to purchase 575,000 shares
of TSG Common Stock at an exercise price of $11 per share (the "Public
Warrants"), warrants to purchase 100,000 shares of TSG Common Stock at a price
of $10.80 per share (the "Underwriter Warrants") and options and rights to
purchase an aggregate of 587,341 shares of TSG Common Stock at exercise prices
ranging from $1.00 per share to $10.812 per share under TSG's 1994 Omnibus
Stock Plan (the "Stock Plan"), 1995 Non-Employee Director Stock Option Plan
(the "Director Plan") and 1995 Employee Stock Purchase Plan (the "Employee
Plan"). Under the terms of the Merger Agreement, Elcotel has agreed to convert
into Elcotel securities outstanding warrants, options and rights to purchase
TSG Common Stock, subject to adjustment pursuant to the terms of the Merger
Agreement. Accordingly, the estimated fair value of outstanding common stock
warrants, options and rights to purchase TSG Common Stock is included as a
component of the merger consideration.
 
  The following table summarizes the number and exercise prices of stock
options and purchase rights outstanding under the Stock Plan, Director Plan
and Employee Plan at June 30, 1997, and as adjusted after giving effect to the
Merger, and their estimated fair values:

LUCENT ACQUISITION PURCHASE PRICE
 
  On September 30, 1997, Elcotel acquired from Lucent certain assets related
to Lucent's payphone manufacturing and component parts business. The purchase
price, including Elcotel's estimated acquisition expenses of $150, was $6,040,
subject to adjustment based on the difference between the book value of
inventories determined pursuant to the acquisition agreement and $3,849.
Assets acquired from Lucent included inventories, machinery, equipment,
tooling and certain other assets related to the payphone manufacturing and
component parts business conducted by Lucent, as well as a license of certain
patent and other intellectual property rights related thereto.
 
  Elcotel borrowed an aggregate of $6,850 under the terms of bank promissory
notes to finance the Lucent Acquisition, including acquisition expenses, debt
issuance expenses of $57 and other general corporate activities, including
acquisition of equipment. These notes consisted of an installment note in the
principal amount of $3,050 payable in eighty four equal monthly installments
of $37, a term note in the principal amount of $2,850 due March 31, 1998 and a
term note in the principal amount of $950 due March 31, 1998. The notes are
collateralized by the assets of Elcotel and bear interest at the Libor rate
plus 2.25 percentage points (7.9% upon issuance). Proceeds from notes from
Elcotel's bank were used to finance the purchase price, including expenses,
and the debt issuance expenses related to the Lucent Acquisition, which
aggregated $6,094. See "Unaudited Pro Forma Balance Sheet Adjustments Related
to the Lucent Acquisition."
 
UNAUDITED PRO FORMA CONSOLIDATED BALANCE SHEET ADJUSTMENTS RELATED TO THE
MERGER
 
  Elcotel has estimated the adjustments to the historical accounts of TSG
required to allocate the Merger consideration to the assets and liabilities of
TSG based on their estimated fair values. The allocations are subject to final
determinations based on independent appraisals and other evaluations of fair
value as of the date of consummation of the Merger. Therefore, the allocations
reflected in the accompanying unaudited consolidated financial information may
differ from the amounts ultimately determined. Unless otherwise indicated,
differences between the amounts included herein and the final allocations are
not expected to have a material effect on the unaudited pro forma consolidated
financial information.
 
  A summary of the allocation of the Merger consideration to the assets and
liabilities of TSG as of June 30, 1997 based on Elcotel's estimates of their
fair value is set forth below.

  Upon consummation of the Merger, Elcotel intends to discontinue certain
products manufactured and marketed by TSG and outsource the assembly of
printed circuit boards assembled by TSG. The allocation of merger
consideration to the estimated fair value of inventories has been decreased by
$3,238 to reflect the estimated net realizable value of inventories related to
products to be discontinued and inventories of components related to printed
circuit board assembly operations.
 
  The fair value of TSG's net assets will vary as of the consummation date of
the Merger based on changes in TSG's financial position between June 30, 1997
and consummation of the Merger.
 
  Identifiable intangible assets are comprised of TSG's trade names at an
estimated fair value of $2,869, assembled workforce at an estimated fair value
of $1,372, product software at an estimated fair value of $611, patented
technology at an estimated fair value of $419 and customer contracts at an
estimated fair value of $2,023.
 
  At June 30, 1997, TSG had net operating loss carryforwards of $11,098
available to reduce future taxable income, which expire from 1998 to 2010.
However, the utilization of these net operating loss carryforwards is subject
to an annual limitation of approximately $210 as a result of a previous change
in ownership of TSG. Accordingly, it is more likely than not that the future
tax benefits of net operating loss carryforwards of approximately $2,909 will
not be realized, and a corresponding valuation allowance has been provided in
the purchase price allocation.
 
  The fair value of accrued liabilities includes estimated expenses of $200 to
be incurred by TSG in connection with the Merger. In addition, the fair value
of accrued liabilities includes the estimated costs to terminate the
employment of certain employees of TSG and to relocate certain employees and
property of TSG. These costs have been estimated based on Elcotel's
preliminary integration and consolidation plan. Employee termination costs
reflecting the estimated cost of severance and salary continuation
arrangements and related employee benefits have been estimated at $195. The
costs of relocating employees and property of TSG have been estimated at $390.
 
  Adjustments to the Unaudited Pro Forma Consolidated Balance Sheet consist of
adjustments to the historical basis of the assets and liabilities of TSG to
arrive at their estimated fair values and other adjustments directly related
to the Merger. Pro forma adjustments to the historical basis of the assets and
liabilities of TSG to arrive at their estimated fair values based on the
purchase allocation are set forth in the following table.

UNAUDITED PRO FORMA INCOME PER COMMON AND COMMON EQUIVALENT SHARE
 
  Pro forma unaudited income per common and common equivalent share for the
year ended March 31, 1997 and three months ended June 30, 1997 is computed on
the basis of the weighted average number of common and dilutive common
equivalent shares outstanding during the period and assuming the issuance of
4,936,848 shares of Elcotel Common Stock to effect the Merger, the assumption
and adjustment of outstanding common stock options and warrants of TSG, and
the issuance of shares of Elcotel Common Stock to Wexford Management and
Cameron occurred on April 1, 1996. The weighted average number of dilutive
common equivalent shares outstanding during the period has been computed based
on the treasury stock method in accordance with Accounting Principles Board
Opinion No. 15, Earnings Per Share.

PRELIMINARY INTEGRATION AND CONSOLIDATION PLAN
 
  Elcotel intends to integrate and consolidate certain operations of TSG and
Lucent into those of Elcotel, including relocation of certain manufacturing
and assembly operations. The planned restructuring of the combined entity is
intended to result in significant cost and expense reductions, lower
manufacturing costs and improved gross profit margins. The planned
restructuring is also intended to result in the establishment of
organizational resources capable of absorbing the anticipated growth in the
business in the foreseeable future. Consequently, Elcotel believes, but cannot
assure, that its post-restructuring operating results will adequately absorb
the ongoing financial impact of the Merger and the Lucent Acquisition, which
consist primarily of non-cash charges related to amortization of goodwill and
intangible assets and additional interest expense related to the Lucent
Acquisition as presented in the accompanying unaudited pro forma consolidated
financial information.
 
FINANCING PLAN
 
  Concurrently with consummation of the Merger, Elcotel intends to secure a
new credit arrangement to refinance existing credit lines of TSG and Elcotel
and to finance working capital requirements of the combined entity. Although
Elcotel believes that it will be able to secure an acceptable financing
agreement, there is no assurance that its efforts will be successful.
 
                     DESCRIPTION OF ELCOTEL CAPITAL STOCK
 
  The statements set forth under this heading with respect to the Delaware
Law, Elcotel's Certificate of Incorporation (the "Elcotel Charter") and
Elcotel's Bylaws are brief summaries thereof and do not purport to be
complete. Such statements are subject to the detailed provisions of Delaware
Law, the Elcotel Charter and the Elcotel Bylaws. See "Available Information."
 
  Under the Elcotel Charter, Elcotel's authorized capital stock consists of
20,000,000 shares of Elcotel Common Stock. Elcotel has proposed to increase
the number of authorized shares of Elcotel Common Stock to 30,000,000 pursuant
to the Elcotel Amendment. See "Additional Proposal No. 2."
 
COMMON STOCK
 
  Dividends and Liquidation Rights. The holders of Elcotel Common Stock are
entitled to receive and share equally in such dividends as may be declared by
the Elcotel Board out of funds legally available therefor. In the event of the
liquidation of Elcotel, holders of Elcotel Common Stock are entitled to share
pro rata in the distribution of Elcotel's assets for such purpose.
 
  Voting Rights. The holders of Elcotel Common Stock elect the Elcotel Board
and act on such other matters as are required to be presented to them under
Delaware Law, the Elcotel Charter or as are otherwise presented to them by the
Elcotel Board. Each holder of Elcotel Common Stock is entitled to one vote per
share. Holders of Elcotel Common Stock are not entitled to cumulate votes in
the election of directors. The directors of Elcotel are elected each year at
the Elcotel Annual Meeting. Directors of Elcotel are elected by a plurality of
votes cast.
 
  Preemptive Rights. Holders of Elcotel Common Stock are not entitled to
preemptive, subscription, redemption or conversion rights with respect to any
shares that may be issued.
 
  The outstanding shares of Elcotel Common Stock are, and the shares of
Elcotel Common Stock issued pursuant to the Merger will be, duly authorized,
validly issued, fully paid and nonassessable.
 
CHANGE OF CONTROL
 
  Section 203 of Delaware Law prohibits generally a public Delaware
corporation, including Elcotel, from engaging in a Business Combination (as
defined below) with an Interested Stockholder (as defined below) for a
 
                                      105
<PAGE>
 
period of three years after the date of the transaction in which an Interested
Stockholder became such, unless: (i) the board of directors of such
corporation approved, prior to the date such Interested Stockholder became
such, either such Business Combination or such transaction; (ii) upon
consummation of such transaction, such Interested Stockholder owns at least
85% of the voting shares of such corporation (excluding specified shares); or
(iii) such Business Combination is approved by the board of directors of such
corporation and authorized by the affirmative vote (at an annual or special
meeting and not by written consent) of at least 66 2/3% of the outstanding
voting shares of such corporation (excluding shares held by such Interested
Stockholder). A "Business Combination" includes (i) mergers, consolidations
and sales or other dispositions of 10% or more of the assets of a corporation
to or with an Interested Stockholder, (ii) certain transactions resulting in
the issuance or transfer to an Interested Stockholder of any stock of such
corporation or its subsidiaries and (iii) certain other transactions resulting
in a financial benefit to an Interested Stockholder. An "Interested
Stockholder" is a person who, together with its affiliates and associates,
owns (or within a three-year period did own) 15% or more of a corporation's
stock entitled to vote generally in the election of directors.
 
                       COMPARISON OF STOCKHOLDER RIGHTS
 
  Upon consummation of the Merger, the stockholders of TSG will become
stockholders of Elcotel. Since both Elcotel and TSG are incorporated under the
laws of the State of Delaware, the rights and privileges of stockholders of
Elcotel and TSG, respectively, which rights and privileges are governed by the
Delaware Law, are substantially identical, except to the extent that their
respective Certificates of Incorporation ("Charters") and Bylaws differ. The
provisions in the Elcotel Charter relating to the lack of preemptive,
subscription or redemption rights are substantially similar to the provisions
in the TSG Charter. See "Description of Elcotel Capital Stock--Common Stock."
In addition, as Delaware corporations, both Elcotel and TSG are subject to the
provisions of Section 203 of the Delaware Law. See "Description of Elcotel
Capital Stock--Change of Control." Although it is not practical to compare all
the differences among the Elcotel Charter and Bylaws and the TSG Charter and
Bylaws, the following is a summary of certain material differences that may
significantly affect the rights of TSG stockholders. This summary is qualified
in its entirety by reference to the full text of such documents. The Elcotel
Charter and Bylaws and the TSG Charter and Bylaws are incorporated by
reference in this Joint Proxy Statement-Prospectus.
 
  The TSG Charter permits the issuance of preferred stock, par value $100 per
share. The Elcotel Charter does not provide for the issuance of preferred
stock. Therefore, the Elcotel Board will not be able to issue shares of
preferred stock that will have rights superior to Elcotel Common Stock without
stockholder approval. For a general description of Elcotel's capitalization,
see "The Merger Agreement--Capitalization of Elcotel." For a general
description of TSG's capitalization, see "The Merger Agreement--Capitalization
of TSG."
 
  Under Delaware Law, special meetings of stockholders may be called by the
Board of Directors and by such other person or persons authorized to do so by
the corporation's certificate of incorporation or bylaws. Both the Elcotel
Bylaws and the TSG Bylaws limit the ability to call special meetings to
directors, so that stockholders may not call a special meeting. Elcotel's
Bylaws are more restrictive because the TSG Board can call a special meeting
upon the vote of a majority of directors present, while the Elcotel Board can
do so only upon the vote of a majority of all directors.

                      ADDITIONAL MATTERS SUBMITTED TO THE
                        VOTE OF ELCOTEL'S STOCKHOLDERS
 
ADDITIONAL PROPOSAL NO. 1: ELECTION OF DIRECTORS
 
  In accordance with Elcotel's Bylaws, a board of seven directors will be
elected to serve until the next annual meeting of stockholders of Elcotel or
until successors to the directors have been elected and have qualified. All
directors are elected annually. It is the intention of the persons named in
the proxy, unless otherwise directed, to vote all proxies in favor of the
election to the Elcotel Board for the nominees listed below, all of whom are
presently directors of Elcotel. The Elcotel Board has no reason to believe
that any of the nominees will be unable or unwilling to be a candidate for
election at the time of the Elcotel Annual Meeting. If any nominee of Elcotel
is unable or declines to serve as a director at the time of the Elcotel Annual
Meeting, the proxies will be voted for any nominee designated by the present
Elcotel Board to fill the vacancy.
 
  Notwithstanding the election of directors of Elcotel at the Elcotel Annual
Meeting, if the Merger is approved by the stockholders of Elcotel and TSG and
is consummated, the number of directors comprising the entire board of
directors of Elcotel will be increased to nine and the directors immediately
after the Effective Time will include the Elcotel director nominees named
below, other than Mr. Wiltse and Mr. Suplee who will retire as directors of
Elcotel, and four individuals, three of whom are currently directors of TSG--
David Steadman, Mark Plaumann and Vincent Bisceglia--being appointed by the
remaining Elcotel Directors. See "The Merger Agreement--Appointment of
Directors."
 
  The Elcotel Board has unanimously recommended a slate of nominees for
election as directors at the Elcotel Annual Meeting. The names of the nominees
for directors of Elcotel, their ages and certain other information is set

nominations for election to Elcotel's Board if such nominations are in writing
and delivered to the Secretary of Elcotel not less than 135 days before the

the Secretary by July 23, 1998. The stockholder making the nomination must
provide information about the persons nominated that is required to be
disclosed in a proxy statement for solicitation of proxies with respect to
nominees for election as directors pursuant to the regulations under the 1934
Act. Only those persons nominated by the Elcotel Board and by stockholders of
Elcotel as described above will be voted upon at the annual meeting of
stockholders of Elcotel.
 
ADDITIONAL PROPOSAL NO. 2: AMENDMENT TO CERTIFICATE OF INCORPORATION
 
 The Elcotel Amendment
 
  At the meeting of the Elcotel Board on September 22, 1997, the Elcotel Board
approved an amendment to the Certificate of Incorporation of Elcotel that
would increase the authorized shares of Elcotel Common Stock from 20,000,000
shares to 30,000,000 shares. At the Elcotel Annual Meeting, the stockholders
of Elcotel will be asked to consider and vote upon a proposal to approve and
adopt the following resolution with respect to such amendment to the
Certificate of Incorporation of Elcotel:
 
  RESOLVED, that Article FOURTH of the Certificate of Incorporation of this
  Corporation is hereby amended to read in its entirety as follows:
 
    "FOURTH--The amount of total authorized capital stock of this
    corporation is 30,000,000 shares of Common Stock, par value $.01 per
    share."
 
 Reasons for the Elcotel Amendment
 
  The number of shares of Elcotel Common Stock issued and reserved for
issuance immediately following the Merger will be approximately 15.5 million
shares. The Elcotel Board believes that it is desirable for Elcotel
 
                                      109
<PAGE>
 
to have additional authorized but unissued shares of Elcotel Common Stock so
as to provide flexibility to act promptly with respect to acquisitions, public
and private financings, stock dividends and other appropriate purposes.
Approval of the increase now will eliminate the delays and expense that
otherwise would be incurred if stockholder approval were required to increase
the authorized number of shares of Elcotel Common Stock for possible future
transactions involving the issuance of additional shares.
 
 
 Effect of the Elcotel Amendment
 
  Additional shares of Elcotel Common Stock authorized pursuant to the Elcotel
Amendment may be issued, subject to certain exceptions, by the Elcotel Board
at such times, in such amounts and upon such terms as the Elcotel Board may
determine, without further approval of the stockholders of Elcotel. Any such
issuance could reduce the current stockholders' proportionate interests in
Elcotel, depending on the number of shares issued and the purpose, terms and
conditions of the issuance. Elcotel stockholders have no preemptive rights to
subscribe to additional shares when issued.
 
 Required Vote
 
  The affirmative vote of a majority of the outstanding shares of Elcotel
Common Stock is required to approve and adopt the Elcotel Amendment.
 
  THE ELCOTEL BOARD UNANIMOUSLY RECOMMENDS THAT THE STOCKHOLDERS OF ELCOTEL
VOTE FOR THE APPROVAL AND ADOPTION OF THE ELCOTEL AMENDMENT.
 
ADDITIONAL PROPOSAL NO. 3: RATIFICATION OF APPOINTMENT OF INDEPENDENT PUBLIC
ACCOUNTANTS
 
  The Board of Directors has appointed Elcotel's present independent public
accountants, Deloitte & Touche llp, for the fiscal year ending March 31, 1998.
This appointment will be submitted to the stockholders of Elcotel for
ratification at the Elcotel Annual Meeting.
 
  The submission of the appointment of Deloitte & Touche llp for ratification
by the stockholders of Elcotel is not required by law or by the Bylaws of
Elcotel. The Elcotel Board is nevertheless submitting it to its stockholders
to ascertain their views. If the stockholders do not ratify the appointment,
the selection of other independent public accountants will be considered by
the Elcotel Board.
 
  Representatives of Deloitte & Touche llp are expected to be present at the
Meeting to respond to appropriate questions and will have the opportunity to
make a statement if they so desire.
 
  THE ELCOTEL BOARD UNANIMOUSLY RECOMMENDS THAT THE STOCKHOLDERS OF ELCOTEL
VOTE FOR THE RATIFICATION OF THE APPOINTMENT OF DELOITTE & TOUCHE LLP.
 
 
ADDITIONAL PROPOSAL NO. 4: AMENDMENT TO 1991 STOCK OPTION PLAN
 
  The 1991 Stock Option Plan was adopted by the Elcotel Board on July 2, 1991
and approved by the stockholders of Elcotel on October 2, 1991. A total of
1,600,000 shares of Elcotel Common Stock are currently reserved for issuance
under the 1991 Stock Option Plan, as amended (the "1991 Plan").
 
  The 1991 Plan provides for the grant to employees of Elcotel of incentive
stock options within the meaning of Section 422 of the Code and nonqualified
stock options. In recognition of Elcotel's need to attract and retain
qualified employees in a highly competitive environment and in view of the
larger number of key employees that would be eligible for the grant of options
under the 1991 Plan following consummation of the Merger, the Elcotel Board
has approved an amendment to the 1991 Plan, subject to stockholder approval,
to increase the number of shares of Elcotel Common Stock reserved for issuance
pursuant to the 1991 Plan by 500,000 shares. The stockholders of Elcotel are
being requested to approve an increase in the number of shares reserved for
issuance under the 1991 Plan by 500,000 shares, from 1,600,000 currently
authorized shares to 2,100,000 shares.
 
                                      110
<PAGE>
 
  The essential features of the 1991 Plan are as follows:
 
  General. At September 30, 1997, 682,066 shares of Elcotel Common Stock had
been issued upon exercise of options granted under the 1991 Plan, options to
purchase 548,838 shares of Elcotel Common Stock were outstanding under the
1991 Plan and 369,096 shares of Elcotel Common Stock remained available for
future grant under the 1991 Plan.
 
  Purpose. The purpose of the 1991 Plan is to enable Elcotel to obtain and
retain the services of key employees and to provide them with increased
motivation and incentive to exert their best efforts on behalf of Elcotel by
enlarging their personal stake in its success.
 
  Administration. The 1991 Plan is administered by the Compensation and Stock
Option Committee of the Elcotel Board (the "Committee") composed of at least
two directors of Elcotel. The Committee has authority, subject to the terms of
the 1991 Plan, to determine the persons to whom options will be granted,
whether the options will be incentive stock options or nonqualified stock
options, the number of shares subject to each option, and the terms and
provisions of each option. Any power granted to the Committee can be exercised
by the Elcotel Board and any determination by the Committee is subject to
review and approval or modification by the Elcotel Board.
 
  Eligibility. Officers and key employees of Elcotel and its subsidiaries are
eligible to receive options. Elcotel estimates that as of September 30, 1997,
there were approximately 48 officers and other key employees of Elcotel who
were eligible to receive options under the 1991 Plan.
 
  Grant. Subject to certain antidilution provisions for stock dividends, stock
splits or other subdivisions or reclassifications of Elcotel Common Stock,
options may be granted under the 1991 Plan to purchase not more than 1,600,000
shares of Elcotel Common Stock, which limit would be increased to 2,100,000
shares pursuant to the proposed amendment. If any option expires or terminates
without being fully exercised and before the 1991 Plan terminates, the
unpurchased shares subject thereto are again available for purposes of the
1991 Plan.
 
  Change in Control. If any proposed transaction may constitute in a change in
control of Elcotel, the Committee, with the approval of the majority of the
members of the Board who are not then holding options, may accelerate the
exercise periods of any options in connection with such transaction.
 
  Nontransferability. Options are not transferable by the optionee except by
will or the laws of descent and distribution. During the lifetime of the
optionee, options are exercisable only by the optionee or to the extent such
exercise would not prevent an option from qualifying as an incentive stock
option, by his or her guardian or legal representative.
 
  Duration and Termination of Options. The maximum term of an option granted
under the 1991 Plan is five years, and an option may be exercised at any time
during its term unless the Committee fixes a specific vesting period or
periods for exercise of any option. The Committee typically grants options
which become exercisable 25 percent each year beginning on the first
anniversary of the date of grant. An optionee's rights under any option
terminate upon the termination of employment for any reason other than death,
disability or retirement, except that the Committee may permit exercise of
such option for a period ending on the earlier of the expiration date of the
option and a date thirty days after the termination of employment as to the
total number of shares purchasable under the option as of the date of
termination. The 1991 Plan provides that in the event of termination of an
optionee's employment by reason of the optionee's death, retirement or
disability, any outstanding option held by such optionee will immediately
become exercisable as to the total number of shares purchasable thereunder and
will remain so exercisable at any time prior to its expiration date or, if
earlier, the first anniversary of termination of the optionee's employment.
 
  Exercise Price. The exercise price per share of Elcotel Common Stock
deliverable upon the exercise of an option is determined by the Committee at
the time of grant. However, the exercise price per share under an option
 
                                      111
<PAGE>
 
may not be less than the greater of 100% (110% in the case of incentive stock
options granted to optionees who own more than ten percent of the voting power
of Elcotel) of the fair market value per share on the date the option is
granted and $0.75. On October 15, 1997, the closing price of Elcotel Common
Stock as reported on the Nasdaq National Market was $8.125. The exercise price
may be paid in cash or by certified or cashier's check or, to the extent
permitted by the Committee, in shares of Elcotel Common Stock.
 
  Plan Duration and Amendment. The 1991 Plan will continue in effect until
July 2, 2001, unless earlier suspended or discontinued. The 1991 Plan may be
modified, terminated or amended at any time by the Elcotel Board except that,
without stockholder approval, the Board may not increase the number of shares
of Elcotel Common Stock which may be issued under the 1991 Plan or modify the
requirements as to eligibility for participation. The modification, amendment
or termination of the 1991 Plan will not affect the rights of an optionee
under any option previously granted to the optionee unless the optionee
consents thereto.
 
  Certain Federal Income Tax Considerations. The following is a brief summary
of the federal income tax consequences of transactions under the 1991 Plan.
This summary is not intended to be exhaustive and does not discuss the tax
consequences of a participant's death or provisions of the income tax laws of
any municipality, state or foreign country in which an optionee may reside. As
stated above, the 1991 Plan permits the grant both of options that qualify as
incentive stock options under Section 422 of the Code and of nonqualified
options. Options which qualify as incentive stock options are entitled to
special tax treatment if shares purchased pursuant to the exercise of such an
option are not disposed of by the optionee within two years from the date of
granting of the incentive stock option and within one year after the issue of
the shares to the optionee upon exercise of the incentive stock option. If
this condition is satisfied neither the grant nor the exercise of incentive
stock options will result in taxable income to the recipient or in a deduction
to Elcotel. If cash is used to exercise, the optionee receives a tax basis in
the stock purchased under an incentive stock option equal to the option price.
The optionee realizes, upon subsequent sale or other disposition of stock
purchased pursuant to an incentive stock option, mid- or long-term capital
gain (or loss) equal to the excess (or deficiency) of the amount realized upon
disposition over such tax basis. For purposes of the alternative minimum tax,
however, the tax treatment of an incentive stock option is similar to the tax
treatment of a nonqualified stock option described below.
 
  An optionee who transfers shares purchased under an incentive stock option
within the one- or two-year holding period, subject to certain exceptions,
will realize, in the year of such disposition, (a) ordinary income equal to
the excess of (i) the fair market value of the shares on the date of exercise
over (ii) the option price and (b) capital gain equal to the excess, if any,
of the amount realized upon disposition over the fair market value of the
shares on the date of exercise. If the amount realized on disposition is less
than the fair market value of the shares on the date of exercise and the
disposition occurs in a sale or exchange with respect to which a loss (if
sustained) would be recognized, then the ordinary income realized by the
optionee will, in most cases, be limited to the excess of the amount realized
over the option price. Upon such a disposition, Elcotel will be entitled to
deduct an amount equal to the ordinary income realized by the optionee.
 
  If an incentive stock option is exercised and the optionee uses previously
owned shares of Elcotel Common Stock to pay the option price, the optionee's
tax basis will carry over to an equal number of shares purchased. The
remaining Elcotel Common Stock received upon exercise of the option will
receive a zero tax basis. The optionee will realize no gain or loss as a
result of the disposition of the previously-owned shares, provided, if the
shares were purchased under an incentive stock option, the holding period
requirement was satisfied.
 
  The grant of nonqualified stock options will not result in any taxable
income to the recipient or in a deduction by Elcotel. However, upon exercise
of a nonqualified option, the optionee will realize ordinary income equal to
the excess of the fair market value of the shares on the date of exercise over
the purchase price, and Elcotel will be entitled to a deduction equal to the
amount the employee is required to treat as ordinary income. If cash is used
to exercise the option, the optionee will receive a tax basis in stock
purchased under a nonqualified option equal to its fair market value at the
time of exercise. On subsequent disposition of the shares, the optionee will
realize capital gain (or loss) equal to the excess (or deficiency) of the
amount realized over such tax basis. The gain or loss will be long-, mid- or
short-term depending on the optionee's holding period for the shares.
 
                                      112
<PAGE>
 
  If a nonqualified option is exercised and the optionee uses previously-owned
shares of Elcotel Common Stock to pay the purchase price, the optionee will
realize ordinary income as described above, but will realize no gain or loss
as a result of the disposition of the previously-owned shares, provided, if
the shares were purchased under an incentive stock option, the holding period
requirement was satisfied. The optionee's tax basis will carry over to an
equal number of shares purchased. The remaining shares of Elcotel Common Stock
will take a tax basis equal to their fair market value.
 
  1991 Plan Benefits. Elcotel cannot now determine the number of options to be
granted in the future under the 1991 Plan to the Named Executive Officers, all
current officers as a group or all employees (including current officers who
are not executive officers) as a group. See "Elcotel Executive Compensation--
Stock Option Grants--Stock Option Exercises and Holdings" for the number of
stock options granted to the Named Executive Officers in the fiscal year ended
March 31, 1997. In the fiscal year ended March 31, 1997, options to purchase
90,000 shares of Elcotel Common Stock were granted to all current executive
officers as a group, and options to purchase 97,000 shares of Elcotel Common
Stock were granted to all employees (including current officers who are not
executive officers). However, pursuant to the employment agreement between
Elcotel and Vincent Bisceglia to become effective upon consummation of the
Merger, Mr. Bisceglia, who would become an Executive Vice President and Chief
Operating Officer of Elcotel, will be entitled to receive an option to
purchase 50,000 shares of Elcotel Common Stock pursuant to the 1991 Plan. It
is also expected that other officers of TSG who become officers of Elcotel
after the Merger will be granted options to purchase Elcotel Common Stock
pursuant to the 1991 Plan, in amounts to be determined by the Committee.
 
  Required Vote. The affirmative vote of the holders of a majority of the
outstanding shares of Elcotel Common Stock present in person or by proxy will
be required to approve this amendment to the 1991 Plan.
 
  THE ELCOTEL BOARD UNANIMOUSLY RECOMMENDS THAT THE STOCKHOLDERS OF ELCOTEL
VOTE "FOR" THE APPROVAL AND ADOPTION OF THE AMENDMENT TO THE 1991 PLAN.
 
ADDITIONAL PROPOSAL NO. 5: AMENDMENTS TO DIRECTORS STOCK OPTION PLAN
 
  The Directors Stock Option Plan was adopted by the Elcotel Board on July 2,
1991 and was approved by the stockholders of Elcotel on October 2, 1991. A
total of 175,000 shares of Elcotel Common Stock are currently reserved for
issuance under the Directors Stock Option Plan, as amended (the "Directors
Plan").
 
  The Directors Plan is a formula plan which provides for the automatic and
nondiscretionary grant of a specified number of options to directors of
Elcotel who are not employees of Elcotel. Those grants occur at the end of
each fiscal year of Elcotel to then current non-employee directors based upon
the number of Elcotel Board committees on which such director then serves and
the number of committee chairperson positions then held.
 
  The purpose of the Directors Plan is to enhance Elcotel's ability to obtain
and retain the services of outside directors and to secure the benefits
arising from those directors having or increasing their equity stake in
Elcotel. In view of the three new non-employee directors that would join the
Elcotel Board upon consummation of the Merger (resulting in a total of six
non-employee directors) and the additional options that would be granted to
those new directors upon such election, the Elcotel Board approved an
amendment to the Directors Plan, subject to stockholder approval, to increase
the number of shares of Elcotel Common Stock reserved for issuance pursuant to
the Directors Plan by 50,000 shares so that Elcotel would continue to have
sufficient shares available to grant stock options pursuant to the Directors
Plan. In addition, the Elcotel Board approved an amendment to the Directors
Plan, subject to stockholder approval, to eliminate the stockholder approval
requirement for changes in the Directors Plan that materially increase the
benefits accruing to participants under the Directors Plan. However,
stockholder approval would still be required for increasing the number of
shares issuable or changing the eligibility requirements for participation.
The Board included this change in the amendment to the Directors Plan in order
to afford more flexibility in adapting the Directors Plan as necessary to best
carry out its purposes of increasing the stake of participants in Elcotel's
continued success and progress and attracting and retaining outside directors.

  The stockholders of Elcotel are being requested to approve an increase in
the number of shares reserved for issuance under the Directors Plan by 50,000
shares, from 175,000 shares to 225,000 shares.
 
  The essential features of the Directors Plan are as follows:
 
  General. At September 30, 1997, 37,000 shares of Elcotel Common Stock had
been issued upon exercise of options granted under the Directors Plan, options
to purchase 100,000 shares of Elcotel Common Stock were outstanding under the
Directors Plan and 38,000 shares of Elcotel Common Stock remained available
for future grant under the Directors Plan.
 
  Purpose. The Directors Plan is intended to secure for Elcotel and its
stockholders the benefits arising from share ownership by directors and the
incentives created when directors acquire or increase their equity interest in
Elcotel and to enhance Elcotel's ability to obtain and retain the services of
non-employee directors.
 
  Administration. The Directors Plan is administered by the Compensation and
Stock Option Committee of the Elcotel Board (the "Committee") composed of at
least two directors of Elcotel. The Committee has authority, subject to the
terms of the Directors Plan, to interpret the provisions of the Directors
Plan, to construe the terms of the options granted thereunder and to
prescribe, amend and rescind rules relating to the Directors Plan.
 
  Eligibility. Members of the Elcotel Board who are not employees of Elcotel
are eligible to receive options under the Directors Plan.
 
  Grant. Each new eligible director receives a one-time grant of an option to
purchase 4,000 shares of Elcotel Common Stock. On the last business day of
each fiscal year of Elcotel, each non-employee director receives an option to
purchase 1,000 shares of Elcotel Common Stock for each committee on which such
director is then serving and an option to purchase 1,000 shares of Elcotel
Common Stock for each committee on which such director is then serving as
chairperson. Subject to certain antidilution provisions for stock dividends,
stock splits or other subdivisions or reclassifications of Elcotel Common
Stock, options may be granted under the Directors Plan to purchase not more
than 175,000 shares of Elcotel Common Stock in the aggregate, which limit
would be increased to 225,000 shares pursuant to the proposed amendment. If
any option expires or terminates without being fully exercised and before the
Directors Plan terminates, the unpurchased shares subject thereto are again
available for purposes of the Directors Plan.
 
  Change in Control. If any proposed transaction may constitute a change in
control of Elcotel, the Committee, with the approval of the majority of the
members of the Board who are not then holding options, may accelerate the
exercise periods of any options in connection with such transaction.
 
  Nontransferability. Options are not transferable by the optionee except by
will or the laws of descent and distribution. During the lifetime of the
optionee, options are exercisable only by the optionee or by his or her
guardian or legal representative.
 
  Duration and Termination of Options. The maximum term of an option granted
under the Directors Plan is five years, and an option may be exercised at any
time during its term unless the Committee fixes a specific vesting period or
periods for exercise of any option. If a grantee's status as director
terminates for any reason other than death, disability or retirement, each
option held by the director under the Directors Plan will, if not already
exercisable before that time, become immediately exercisable and in any event
remain exercisable until the earlier of its expiration date and the first
anniversary of termination of the grantee's status as director. If the
grantee's status as director terminates for any reason other than death,
disability or retirement, each option held by the director under the Directors
Plan will remain exercisable until the earlier of its expiration date and 30
days after termination of director status.
 
  Exercise Price. The exercise price per share of Elcotel Common Stock
deliverable upon the exercise of an option is the greater of $2.00 or 100% of
the fair market value per share on the date the option is granted. On
 
                                      114
<PAGE>
 
October 15, 1997, the closing price of Elcotel Common Stock as reported on the
Nasdaq National Market was $8.125. The exercise price may be paid in cash or
by certified or cashier's check or, to the extent permitted by the Committee,
in shares of Elcotel Common Stock.
 
  Plan Duration and Amendment. The Directors Plan will continue in effect
until July 2, 2001, unless earlier suspended or discontinued. The Directors
Plan may be modified, terminated or amended at any time by the Elcotel Board
except that, without stockholder approval, the Board may not materially
increase the benefits to optionees (which provision would be deleted pursuant
to the proposed amendment), increase the number of shares which may be issued
under the Directors Plan or modify the requirements as to eligibility for
participation. The modification, amendment or termination of the Directors
Plan will not affect the rights of an optionee under any option previously
granted to the optionee unless the optionee consents thereto.
 
  Certain Federal Income Tax Considerations. The following is a brief summary
of the federal income tax consequences of transactions under the Directors
Plan. This summary is not intended to be exhaustive and does not discuss the
tax consequences of a participant's death or provisions of the income tax laws
of any municipality, state or foreign country in which an optionee may reside.
The Directors Plan permits the grant only of nonqualified options. The grant
of nonqualified stock options will not result in any taxable income to the
recipient or in a deduction by Elcotel. However, upon exercise of a
nonqualified option, the optionee will realize ordinary income equal to the
excess of the fair market value of the shares on the date of exercise over the
purchase price, and Elcotel will be entitled to a deduction equal to the
amount the employee is required to treat as ordinary income. If cash is used
to exercise the option, the optionee will receive a tax basis in stock
purchased under a nonqualified option equal to its fair market value at the
time of exercise. On subsequent disposition of the shares, the optionee will
realize capital gain (or loss) equal to the excess (or deficiency) of the
amount realized over such tax basis. The gain or loss will be long-, mid- or
short-term depending on the optionee's holding period for the shares.
 
  If a nonqualified option is exercised and the optionee uses previously-owned
shares of Elcotel Common Stock to pay the purchase price, the optionee will
realize ordinary income as described above, but will realize no gain or loss
as a result of the disposition of the previously-owned shares. The optionee's
tax basis will carry over to an equal number of shares purchased. The
remaining shares of Elcotel Common Stock will take a tax basis equal to their
fair market value.
 
  Directors Plan Benefits. Elcotel cannot now determine the number of options
to be granted in the future under the Directors Plan to all current directors
who are not executive officers as a group, to each nominee for election as a
director or to each associate of such directors or nominees. In the fiscal
year ended March 31, 1997, options to purchase 17,000 shares of Elcotel Common
Stock were granted to all current directors who were not executive officers as
a group. See "Additional Matters Submitted to the Vote of Elcotel's
Stockholders--Additional Proposal No. 1: Election of Directors--Directors'
Compensation."
 
  Required Vote. The affirmative vote of the holders of a majority of the
outstanding shares of Elcotel Common Stock present in person or by proxy will
be required to approve the amendments to the Directors Plan.
 
  THE ELCOTEL BOARD UNANIMOUSLY RECOMMENDS THAT THE STOCKHOLDERS OF ELCOTEL
VOTE "FOR" THE APPROVAL AND ADOPTION OF THE AMENDMENTS TO THE DIRECTORS PLAN.

           ELCOTEL COMPENSATION AND STOCK OPTION COMMITTEE REPORT ON
                            EXECUTIVE COMPENSATION
 
  This report, prepared by Elcotel's Compensation and Stock Option Committee
(the "Compensation Committee"), reflects executive compensation policy and
philosophy applicable to fiscal year 1997. All members of the Compensation
Committee are non-employee directors.
 
  Elcotel's executive compensation plans have been structured to attract,
retain and incentivize talented executives capable of executing the strategies
and plans essential to a fast growth, technology-based company in the
traditional and emerging competitive telecommunications markets. The policies
and plans are designed to ensure individual executives receive compensation in
direct relationship to their contribution to key corporate financial and
strategic goals that are focused on short-term and long-term business success
while increasing shareholder values. The plans are designed to be equitable
and to recognize the balance between short-term operating performance and
stock performance.
 
  For fiscal year 1997, the Compensation Committee adopted an incentive
compensation bonus plan for the senior executive officers: C. Shelton James,
CEO and Tracey L. Gray, President/COO, related to overall corporate financial
performance. Discretionary bonuses up to 50% of base salary would be paid
based on Elcotel's performance as measured against key financial factors,
revenues, operating profits and increasing profitability. The Compensation
Committee determined the appropriate level of bonus based on overall
consideration of Elcotel's performance for the fiscal year. The Compensation
Committee awarded a $33,930 bonus to Mr. James and a $60,450 bonus to Mr.
Gray.
 
  For fiscal year 1997, the Compensation Committee adopted a discretionary
incentive compensation bonus plan for corporate officers other than Mr. James
and Mr. Gray. Maximum bonus levels of 20% to 25% of base salary would be paid
based on Elcotel achieving operating performance goals established for
revenues, gross margins, operating profits and personal objectives related to
each officer's area of responsibility. Recommendations regarding the bonus
payment to each officer were presented by Mr. Gray once final results were
available. No bonus is payable under the plan unless Elcotel reports profits.
All bonuses awarded under the plan are paid out in equal annual amounts over
four years. The corporate performance goals and the personal objectives of
each officer are approved at the beginning of each fiscal year following the
fiscal year business plan approval.
 
  In October of 1996, the Compensation Committee authorized adjustments in all
corporate officers' base compensation. This adjustment represented the first
increase in officer base compensation since July of 1995. The adjustments
represented a combination of annual salary review adjustments as well as
structural adjustments to address industry and competitive issues faced by
Elcotel as it attempts to attract a more talented and experienced executive
team. The Compensation Committee was briefed on comparable officer
compensation in the industry from a variety of salary survey reports and
competitors' officer compensation structures and also considered data provided
by Towers Perrin which had been commissioned by the Compensation Committee to
advise on compensation issues.
 
  Mr. James and Mr. Gray's base compensation was adjusted from $80,000 to
$87,000 and from $141,000 to $155,000, respectively, at the recommendation of
the Compensation Committee effective October 1, 1996.
 
  The Compensation Committee recognizes the merits and value of stock
ownership by Elcotel's executives as a basis for retention and aligning the
executive's interests with the stockholders of Elcotel. The use of stock
option grants has become a key element of the equity-based compensation plans
designed to increase the equity interest of Elcotel's executives and combined
with performance-based incentive compensation, ensures a balanced perspective
focused on these two objectives.
 
  The Committee also recognizes that in times of general economic distress, it
may not be economically practical to maintain total compensation, particularly
for senior managers, within the targeted ranges.
 
                                      122
<PAGE>
 
  To ensure executive compensation is appropriately aligned with performance
and the financial interest of stockholders, and that senior managers share
with those associates subject to layoff and shorter work weeks the financial
impact of difficult economic conditions, it has been the practice of the
Compensation Committee to recommend salary freezes or temporary salary
reduction for senior managers during periods of general economic distress and
poor corporate performance.

                   AGREEMENT AND PLAN OF MERGER


         AGREEMENT AND PLAN OF MERGER dated as of August 13, 1997 among ELCOTEL,
INC., a Delaware corporation ("Elcotel"), TECHNOLOGY SERVICE GROUP, INC., a
Delaware corporation ("TSG"), and ELCOTEL HOSPITALITY SERVICE, INC., a Delaware
corporation and a wholly-owned subsidiary of Elcotel ("Merger Subsidiary").

         WHEREAS, the respective Boards of Directors of Elcotel and TSG have
approved, and deem it advisable and in the best interests of their respective
stockholders to consummate the acquisition of TSG by Elcotel by means of a

herein;

         WHEREAS, for United States federal income tax purposes, it is intended
that the Merger contemplated by this Agreement qualify as a "reorganization"
within the meaning of Section 368 of the Internal Revenue Code of 1986, as
amended, and the rules and regulations promulgated thereunder (the "Code"); and

         WHEREAS, as a condition and inducement to Elcotel entering into this
Agreement and incurring the obligations set forth herein, concurrently with the
execution and delivery of this Agreement, Elcotel is entering into a Voting
Agreement with Wexford Partners Fund, L.P. ("Wexford") and Fundamental
Management Corporation ("Fundamental", together with Wexford, the

pursuant to which, among other things, Wexford has agreed to vote the shares of
TSG Common Stock owned by it in favor of this Agreement and the Merger and other
transactions provided for herein and Fundamental has agreed to vote the shares
of Elcotel Common Stock owned by it in favor of the issuance of shares of
Elcotel Common Stock pursuant to the Merger and the other transactions
contemplated by the Merger.

                             ARTICLE I
                            THE MERGER

         Section 1.01   The Merger.

              (a) Upon the terms and subject to the conditions set forth in this
Agreement, at the Effective Time, Merger Subsidiary shall be merged (the
"Merger") with and into TSG in accordance with the Delaware General Corporation
Law (the "Delaware Law"), whereupon the separate existence of Merger Subsidiary
shall cease, and TSG shall continue as the surviving corporation (the "Surviving
Corporation");

              (b) Upon the terms and subject to the conditions of this
Agreement, the closing of the Merger (the "Closing") shall take place at 10:00
a.m. on a date to be specified by the parties (the "Closing Date"), which shall
be no later than the fifth business day after satisfaction of the conditions set
forth in Article 6, at the offices of Schnader, Harrison, Segal & Lewis LLP,
14th Floor, 330 Madison Avenue, New York, New York 10017, unless another time,
date or place is agreed to in writing by the parties hereto;
 
              (c) Upon the Closing, TSG and Merger Subsidiary will file a
certificate of merger with the Secretary of State of the State of Delaware and
make all other filings or recordings required by Delaware Law in connection with
the Merger. The Merger shall become effective at such time as the certificate of
merger is duly filed with the Secretary of State of the State of Delaware or at
such later time as is agreed by Elcotel and TSG and specified in the certificate
of merger (the "Effective Time");

              (d) The Merger shall have the effects set forth in Section 259 of
the Delaware Law; and

              (e) 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 1.02   Conversion of Shares. 

              (a) 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:

                   (i) 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;

                                2
<PAGE>
 
                   (ii) each share of common stock, par value $0.01 per share,
    of Merger Subsidiary outstanding immediately prior to the Effective Time
    shall automatically be 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
 
                   (iii) 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").

              (b) 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);

              (c) 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
 
              (d) 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 1.03   Surrender and Payment. 

              (a) 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;

              (b) 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;

              (c) 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;

              (d) 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;

                                 4
<PAGE>
 
              (e) 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;

              (f) 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;

              (g) 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 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

              (h) 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 1.04   Stock Option Plans. 

              (a) 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

                                 5
<PAGE>
 
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;

              (b) 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

              (c) 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 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 1.05   TSG Warrants. 

              (a) 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.

              (b) 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 1.06 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.

                            ARTICLE III
               REPRESENTATIONS AND WARRANTIES OF TSG

         TSG represents and warrants to Elcotel that:

         Section 3.01 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

                                8
<PAGE>
 
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.
 
         Section 3.02 Corporate Authorization. The execution, delivery and
performance by TSG of this Agreement and the consummation by TSG of the
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 3.03 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.

                                9
<PAGE>
 
         Section 3.04 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

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 3.21   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

without limitation, any contract, agreement or other arrangement (i) providing

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.

     Section 3.23   Takeover Statutes. The Board of Directors of TSG 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
this Agreement and the Voting Agreement the provisions of Section 203 of the
Delaware Law. No other "fair price", "moratorium", "control share acquisition"
or other similar antitakeover statute or regulation enacted under state or
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.

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.

applicable as a result of such membership or holding has not expired.

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

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

information currently outstanding that could affect the Taxes of Elcotel or any
of its Subsidiaries.

other governmental agency (or closed by applicable statutes of limitations) and
all Tax liabilities in respect thereof have been finally determined for all

                                       43
<PAGE>
 
directors, employees, investment bankers, consultants and other agents of TSG

terminate, any existing activities, discussions or negotiations with any parties
with respect to any of the foregoing, and it will take the necessary steps to

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

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 (ii) to the extent required, complying with Rule 14e-2 promulgated
under the 1934 Act with regard to an Alternative Proposal.

     Section 5.04   Approval of Stockholders.  

           (a)   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

                                       44
<PAGE>
 
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;

           (b)   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;

           (c)   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 5.05   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

                                       45
<PAGE>
 
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.

and other information as such Persons may reasonably request and will instruct
Elcotel's employees, auditors, counsel and financial advisors to cooperate with
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.

the Merger.

         Section 5.15   Tax Treatment. Each of Elcotel and TSG shall not take
any action and shall not fail to take any action which action or failure to act
would cause, or would be reasonably likely to cause, Elcotel, TSG or their

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
Merger, and TSG shall use its reasonable efforts to obtain the opinion of

Effective Time whether prior to or after Stockholders' Approval:

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

              (b)  By either TSG or Elcotel upon notification to the non-
terminating party by the terminating party;

                   (i)   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;

                   (ii)  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

              (c)  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

              (a)  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;

              (b)  (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

<PAGE>
 
                   (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

    wire transfer of same day funds upon receipt of appropriate 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

              (c)  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

Gentlemen:

You have requested that we render an opinion as to the fairness, from a
financial point of view, to Elcotel, Inc. (the "Company") under Section 4.25 of
the Agreement and Plan of Merger (the "Merger Agreement", draft date August 2,
1997), among the Company, Technology Services Group, Inc. ("TSG") and Merger
Subsidiary, of the Merger.  Unless otherwise defined herein, all capitalized
terms are as defined in the Merger Agreement.

Pursuant to the Merger Agreement, at the Effective Time, Merger Subsidiary shall
be Merged with and into TSG in accordance with the Delaware Law, whereupon the
separate existence of Merger Subsidiary shall cease, and TSG shall continue as
the Surviving Corporation.  At the Effective Time by virtue of the Merger:  (i)
each share of common stock of TSG held by TSG as treasury stock or owned by the
Company or any subsidiary of the Company immediately prior to the Effective Time
shall automatically be canceled and retired without any conversion thereof, and
no common stock of the Company or other consideration shall be delivered in
exchange therefor; (ii) each share of common stock of Merger Subsidiary
outstanding immediately prior to the Effective Time shall automatically be
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 (iii) each share of TSG Common Stock outstanding
immediately prior to the Effective Time shall, except as otherwise provided in
(i) above, automatically be converted into the right to receive 1.05 shares of
fully paid and non-assessable common stock of the Company.
<PAGE>
 
Board of Directors
ELCOTEL,INC.
August 5,1997


In arriving at our opinion, we have, among other things:  (i) reviewed the
Merger Agreement and other related documents; (ii) reviewed such publicly
available business and financial information relating to the Company and TSG as
we deemed appropriate; (iii) reviewed certain internal financial and operating
information relating to the Company and TSG (including financial forecasts)
prepared by their respective managements; (iv) discussed the past and current
operations and financial condition and prospects of the Company with the senior
management of the Company; (v) discussed the past and current operations and
financial condition and prospects of TSG with the senior management of TSG; (vi)
reviewed pro forma financial statements (including financial forecasts) of the
Company and TSG on a combined basis (the "Combined Companies") prepared jointly
by the management of the Company and TSG; and (vii) reviewed recent stock market
data relating to the Company and TSG.

We have also considered certain financial data of the Company and TSG and have
compared that data from a financial point of view with similar data for other
publicly-held companies in businesses similar to those of the Company and TSG.
We have also considered such other information, financial studies, analyses and
investigations and financial, economic and market criteria which we deemed
relevant.

In connection with our review, we have not independently verified any of the
foregoing information, and have relied on its being complete and accurate in all
material respects and we have further relied upon the assurances of the Company
management that they are unaware of any facts that would make the information
provided to us incomplete or misleading in any material respect.  With respect
to the financial forecasts, we have assumed that they have been reasonably
prepared on a basis reflecting the best currently available estimates and
judgments of the Company's and TSG' management as to the expected future
financial performance of the Company, TSG and the Combined Companies.  In
addition, we have not made any independent evaluation or appraisal of the
individual assets of the Company or TSG, nor have we been furnished with any
such appraisals.

Based upon and subject to the foregoing, including that various assumptions and
limitations set forth herein, it is our opinion that the Merger pursuant to the
Merger Agreement, is fair, from a financial point of view, to the Company.

                          INDEPENDENT AUDITORS' REPORT


Stockholders
Technology Service Group, Inc.


We have audited the accompanying consolidated balance sheets of Technology
Service Group, Inc. and subsidiary as of March 28, 1997 and March 29, 1996, and
the related consolidated statements of operations, changes in stockholders'
equity (deficit), and cash flows for the years ended March 28, 1997 and March
29, 1996, five months ended March 31, 1995, and the seven months ended October
30, 1994.  These financial statements are the responsibility of the Company's
management.  Our responsibility is to express an opinion on the financial
statements based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards.  Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement.  An audit includes examining on a test basis, evidence supporting
the amounts and disclosures in the financial statements.  An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion, such consolidated financial statements present fairly, in all
material respects, the financial position of Technology Service Group, Inc. and
subsidiary at March 28, 1997 and March 29, 1996 and the results of their
operations and their cash flows for the years ended March 28, 1997 and March 29,
1996, the five months ended March 31, 1995, and the seven months ended October
30, 1994 in conformity with generally accepted accounting principles.

                         TECHNOLOGY SERVICE GROUP, INC.
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                  (Dollars in thousands except per share data)


1.   THE COMPANY

          Technology Service Group, Inc. ("TSG") was incorporated in the State
of Delaware in 1975. TSG designs, develops, manufactures and markets public
communication products including microprocessor-based ("smart") wireline and
wireless payphone systems, electronic wireline payphone products and related
payphone components.  TSG also provides payphone and payphone component repair,
refurbishment and upgrade conversion services.  The accompanying financial
statements include the accounts of TSG's wholly-owned subsidiary, International
Service Technologies, Inc. ("IST"), which has a foreign division located in
Taiwan.


2.   ACQUISITION

          On October 31, 1994, TSG Acquisition Corp. ("TSG Acquisition"), a non-
operating corporation wholly-owned by Wexford Partners Fund, L.P. ("Wexford"),
acquired all of the outstanding capital stock of TSG pursuant to an Agreement
and Plan of Merger dated October 11, 1994 (the "Plan of Merger") between
Wexford, TSG Acquisition, TSG and the majority holders of TSG's capital stock
(the "Acquisition").  TSG Acquisition paid an aggregate of $3.5 million in cash
pursuant to the Plan of Merger, including $330 of contingent consideration that
was placed in escrow.  The consideration consisted of $3,004 to acquire the
outstanding capital stock of TSG and $496 to retire a subordinated master
promissory note of $400 payable to former stockholders and related accrued
interest and preference fees of $96.  Cash payments to former stockholders on
October 31, 1994 aggregated $2,992 after deducting $278 to retire certain
obligations of TSG and $230 placed in escrow. Consideration placed in escrow of
$330 consisting of cash of $230 and a subordinated note of TSG payable to one of
the former stockholders in the principal amount of $100 was distributed to
former stockholders in September 1995 upon compliance with indemnification
provisions set forth in the Plan of Merger.

          In conjunction with the Acquisition, TSG Acquisition was merged into
TSG, which was then wholly-owned by Wexford. The outstanding shares of TSG's
capital stock and rights to purchase TSG's capital stock, including preferred
stock purchase warrants, at October 31, 1994 and TSG's Incentive Stock Option
Plan were cancelled and the outstanding shares of capital stock of TSG
Acquisition were exchanged for one share of TSG's common stock, $.05 par value
(the "merger share").  TSG is sometimes referred to as the "Predecessor" for
periods prior to the Acquisition.

          In addition, TSG entered into an Investment Agreement (the "Investment
Agreement") with Wexford and certain former investors (collectively the
"investors").  TSG issued 3.5 million shares of common stock, $.01 par value, in
exchange for the merger share held by Wexford.  Also, TSG borrowed $2.8 million
from the investors and issued 10% interest bearing subordinated promissory notes
due November 1, 1999 (see Note 7).

          The Acquisition has been accounted for using the purchase method of
accounting.  Accordingly, the aggregate purchase price of $3,170 (excluding
contingent consideration) was pushed down and allocated to assets and
liabilities of TSG as of October 31, 1994 (the date of acquisition) based upon
their estimated fair values.  The excess of the purchase price over the fair
value of the net assets acquired of $3,854 was recorded as goodwill (see Note
6).  The increase in the aggregate purchase price and goodwill upon the
distribution of escrow consideration of $330 was recognized in TSG's financial
statements during the year ended March 29, 1996.

</TABLE>

          The accompanying financial statements at March 29, 1996 and March 28,
1997 and for the five months ended March 31, 1995 and years ended March 29, 1996
and March 28, 1997 reflect the effects of the Acquisition. Assuming the
Acquisition had occurred on April 2, 1994, TSG's and the Predecessor's net loss
for the year ended March 31, 1995 including proforma adjustments for
depreciation, interest and amortization of assets to give effect to the
accounting bases recognized in recording the Acquisition would have approximated
$1,599 (unaudited), or a loss of $.45 per share (unaudited), as compared to the
reported loss of $1,488 ($423 for the seven months ended October 30, 1994 and
$1,065 for the five months ended March 31, 1995). The proforma adjustments
include an increase in the amortization of goodwill and other intangible assets
of approximately $140 (unaudited) due to the increase in the basis of intangible
assets and their estimated useful lives, a decrease in depreciation of
approximately $24 (unaudited) due to an increase in the basis of property and
equipment and their estimated useful lives and a decrease in interest expense of
approximately $6 (unaudited) due to revaluation of capital lease obligations,
the financing received from the investors and the repayment of indebtedness
under TSG's revolving credit agreement.


3.   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

          A summary of the significant accounting policies followed by TSG is
set forth below:

Fiscal Year

          TSG operates on a fiscal year ending the Friday nearest March 31
resulting in a 52/53 week year. The accompanying consolidated financial
statements include the audited financial statements of the Predecessor for the
seven months (30 weeks) ended October 30, 1994 and TSG, subsequent to the
Acquisition, for the five months (22 weeks) ended March 31, 1995 and years (52
weeks) ended March 29, 1996 and March 28, 1997.

                                      C-7
<PAGE>
 
Consolidation

          All significant intercompany balances and transactions have been
eliminated in consolidation.

Translation of Foreign Currency

          The financial position and results of operations of TSG's foreign
division are measured using local currency as the functional currency. Assets
and liabilities of TSG's foreign division are translated into United States
dollars at the applicable exchange rate in effect at the end of the period.
Income statement accounts are translated at the average rate in effect over the
period. Translation adjustments arising from the use of differing exchange rates
from period to period are accumulated in a separate component of stockholders'
equity. Gains and losses resulting from foreign currency transactions are
included in income in the period in which these transactions occur. The effects
of foreign currency translation on TSG's financial position and results of
operations are not significant. Also, the operations, assets and liabilities of
TSG's foreign division are not significant.

Cash

          TSG's cash balances serve as collateral under a loan agreement (see
Note 7) and, accordingly, are restricted.

Inventories

          Inventories are stated at the lower of cost or market. Cost is
determined based upon the first-in, first-out ("FIFO") method or standard cost,
which approximates cost on a FIFO basis.

          Reserves to provide for potential losses due to obsolescence and
excess quantities are established in the period in which such losses occur.

Property and Equipment

          Property and equipment is recorded at cost less accumulated
depreciation. Depreciation is computed using the straight-line method over the
established useful lives of the assets as follows:

<TABLE>
<CAPTION>
                                                Predecessor         Company
                                              ---------------    -------------
<S>                                           <C>                <C> 
Building and building improvements                   30 years         30 years
Machinery and equipment                            2-10 years        2-5 years
Furniture and fixtures                             2-10 years        2-3 years
Leasehold improvements                             5-15 years          5 years
</TABLE> 
 
          Additions, improvements and expenditures that significantly extend the
useful life of an asset are capitalized. Expenditures for repairs and
maintenance are charged to operations as incurred. When assets are retired or
disposed of, the cost and accumulated depreciation thereon are eliminated from
the accounts, and any gains or losses are included in income.
 
Revenue Recognition
 
          Sales and related costs, including reserves for warranties and
returns, are recorded by TSG upon shipment of products. Deferred revenue
consists of prepayments from customers and the refundable portion of proceeds
received from the sale of software (see Note 14) which is classified according
to the terms of the repayment obligation. Deferred revenue is recognized as
earned upon shipment of products or pursuant to the terms of the sales contract.
 

                                      C-8
<PAGE>
 
Engineering, Research, and Development Costs
 
          Costs and expenses incurred for the purpose of product research,
design and development are charged to operations as incurred. Engineering,
research and development costs consist primarily of costs associated with
development of new products and manufacturing processes. TSG capitalizes as
other assets certain product software development costs once technological
feasibility has been achieved. Commencing upon initial product release, these
costs are amortized based on the straight-line method over the estimated useful
life of the product, which is generally five years. Capitalized software
development costs are reported at the lower of cost, net of accumulated
amortization, or net realizable value (see Note 6). Software development costs
incurred prior to achieving technological feasibility are charged to research
and development expense as incurred.
 
Stock-Based Compensation
 
          In October 1995, the Financial Accounting Standards Board issued
Statement of Financial Accounting Standards No. 123, Accounting for Stock-Based
Compensation ("SFAS 123"). SFAS 123, which is effective for fiscal years
beginning after December 15, 1995, defines a fair value based method of
accounting for compensation cost related to stock options and other forms of
stock-based compensation plans. This statement gives entities a choice of
recognizing related compensation costs by adopting the new fair value method or
to continue to measure compensation using the intrinsic value approach contained
in Accounting Principles Board Opinion 25 ("APB 25"), the former standard. If
the former standard for measurement is elected, SFAS 123 requires supplemental
disclosure to show the effects of using the new measurement criteria. TSG has
elected to continue to apply the former standards contained in APB 25, and as a
result, TSG adopted the pro forma disclosure requirements of SFAS 123 during the
year ended March 28, 1997 (see Note 9). APB 25 requires compensation expense for
stock-based compensation plans to be recognized based on the difference, if any,
between the per-share market value of the stock and the option exercise price on
the measurement date, which is generally the grant date. TSG has not recognized
any compensation expense with respect to stock options granted under TSG's plans
in accordance with the requirements of APB 25.
 
Fair Value of Financial Instruments and Concentration of Credit Risk
 
          The estimated fair value of TSG's cash, accounts receivable, accounts
payable and outstanding indebtedness approximates the carrying amounts due
principally to their short maturities. Accounts receivable represent the primary
financial instrument which potentially subjects TSG to concentrations of credit
risk. TSG does not require its customers to provide collateral with respect to
amounts owed, but periodically evaluates the credit of its customers (see Note
14). The allowance for non-collection of accounts receivable is estimated based
upon the expected collectibility of all accounts receivable.
 
Goodwill
 
          The excess of the purchase price over the fair value of TSG's assets
and liabilities at the date of the Acquisition is being amortized to operations
on a straight-line basis over a period of 35 years. At each balance sheet date,
TSG evaluates the realizability of goodwill based on its expectations of future
undiscounted cash flows. Based on TSG's most recent analysis, TSG believes that
no material impairment of goodwill exists at March 28, 1997.
 
Income Taxes
 
          Income tax expense (benefit) is based upon income (loss) recognized
for financial statement purposes and includes the effects of temporary
differences between such income (loss) and that recognized for tax purposes in
accordance with Statement of Financial Accounting Standards No. 109 (SFAS 109),
"Accounting for Income Taxes." SFAS 109 requires recognition of deferred tax
assets and liabilities for the expected future tax consequences of events that
have been included in the financial statements or tax returns. Using the enacted
tax rate in effect for the year in which the differences are expected to
reverse, deferred tax assets and liabilities are determined based upon the
differences between the financial reporting basis and income tax basis of the
assets and liabilities (see Note 10). A valuation allowance is established for
deferred tax assets to the extent realization thereof is not assured.

Income (Loss) Per Common and Common Equivalent Share
 
          Income (loss) per common and common equivalent share for the five
months ended March 31, 1995 and years ended March 29, 1996 and March 28, 1997 is
computed on the basis of the weighted average number of common and dilutive
common equivalent shares outstanding during the period, except as required by
Accounting Principles Board Opinion No. 15, Earnings per Share, all outstanding
options and warrants during the year ended March 28, 1997 have been included in
the calculation in accordance with the modified treasury stock method, and
except as required by Securities and Exchange Commission Staff Accounting
Bulletin ("SECSAB") Topic 4:D, stock issued and stock options covering 89,000
shares of common stock granted during the 12 months prior to a May 10, 1996
initial public offering (see Note 9) at prices below the public offering price
have been included in the calculation of weighted average number of common and
common equivalent shares outstanding as if they were outstanding as of the
beginning of the period. Also, as a result of the Acquisition, income (loss) per
share is not presented for periods prior to the five months ended March 31, 1995
in accordance with SECSAB Topic 1:B2.
 
          In February 1997, the Financial Accounting Standards Board issued
Statement of Financial Accounting Standards No. 128, Earnings Per Share ("SFAS
128"). SFAS 128 requires disclosure of basic earnings per share based on income
available to common stockholders and the weighted average number of common
shares outstanding during the period, and diluted earnings per share based on
income available to common stockholders and the weighted average number of
common and dilutive potential common shares outstanding during the period. The
adoption of SFAS 128 is required for fiscal years ending after December 15,
1997, and earlier adoption is not permitted. Had TSG adopted SFAS 128 during the
years ended March 29, 1996 and March 28, 1997, basic earnings per share on a pro
forma basis would have been $.34 and $.22 per share, respectively, and diluted
earnings per share on a pro forma basis would have been $.30 and $.21 per share,
respectively.
 
New Accounting Pronouncements
 
          In February 1997, the Financial Accounting Standards Board issued
Statement of Financial Accounting Standards No. 129, Disclosure of Information
about Capital Structure ("SFAS 129"). SFAS 129 requires a Company to explain the
privileges and rights of its various outstanding securities, the number of
shares issued upon conversion, exercise or satisfaction of required conditions
during the most recent annual fiscal period, liquidation preferences of
preferred stock and other matters with respect to preferred stock. Although the
statement is effective for periods ending after December 15, 1997, TSG's
financial statement disclosures are in compliance with SFAS 129.
 
          In June 1997, the Financial Accounting Standards Board issued
Statement of Financial Accounting Standards No. 130, Reporting Comprehensive
Income ("SFAS 130"). SFAS 130 establishes standards for reporting and display of
comprehensive income and its components in a full set of general-purpose
financial statements. Comprehensive income is defined as the change in equity of
a business during a period from transactions and events and circumstances from
non-owner sources, and includes all changes in equity during a period except
those resulting from investments by owners and distributions to owners. SFAS 130
is effective for fiscal years beginning after December 15, 1997. The adoption of
SFAS 130 will not have a material effect on TSG's results of operations or
financial position.
 
          Also, in June 1997, the Financial Accounting Standards Board issued
Statement of Financial Accounting Standards No. 131, Disclosure about Segments
of an Enterprise and Related Information ("SFAS 131"). SFAS 131 requires public
entities to report certain information about operating segments, their products
and services, the geographic areas in which they operate, and their major
customers, in complete financial statements and in condensed interim financial
statements issued to stockholders. SFAS 131 is effective for fiscal years
beginning after December 15, 1997. The adoption of SFAS 131 will not have a
material effect on TSG's results of operations or financial position.
 
Use of Estimates

                                      C-10
<PAGE>
 
          The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 




Interim Financial Information

          The financial statements as of and for the three months ended June 27,
1997 and June 28, 1996 are unaudited. In the opinion of management, all
adjustments, including recurring adjustments, necessary for a fair presentation
of the results of operations have been included and these adjustments include no
unusual items.

          During the year ended March 28, 1997, TSG closed a one hundred
thousand square foot manufacturing facility located in Paducah, Kentucky and
assigned its capital lease obligation to an unaffiliated third party.
Accordingly, TSG recorded the retirement of the outstanding capital lease
obligation and the disposition of the property during the year ended March 28,
1997. In connection with this transaction, TSG realized a gain of $44
representing the difference between the outstanding lease obligation ($933) plus
the proceeds received ($50) and the net book value of the property ($939).


6.   OTHER ASSETS AND GOODWILL

          Other assets at March 29, 1996 and March 28, 1997, net of accumulated

          The excess of the purchase price over the fair value of net assets
acquired in connection with the Acquisition (goodwill), including the escrow
consideration distributed during the year ended March 29, 1996, aggregated
$4,184. Tax benefits of acquired deferred tax assets of $211 and $442 during the
years ended March 29, 1996 and March 28, 1997, respectively, were applied
against the excess purchase price (see Note 10). Accumulated amortization of
goodwill at March 29, 1996 and March 28, 1997 was $169 and $278, respectively.

          Other intangible assets recorded in connection with the Acquisition
consisted of product software of $234 patents of $164, customer contracts of
$126 and unpatented technology of $60. These assets are being amortized over
estimated useful lives ranging from less than two years to five years, and are
reported at the lower of cost, net of accumulated amortization, or net
realizable value.

          During the year ended March 28, 1997, TSG capitalized software
development costs of $422 in connection with the development of new products.
Software development costs during the five months ended March 31, 1995 and year
ended March 29, 1996 were not significant.

          Amortization expense for the seven months ended October 30, 1994, five
months ended March 31, 1995 and years ended March 29, 1996 and March 28, 1997
amounted to $193, $100, $277 and $277, respectively.


7.   BORROWINGS UNDER REVOLVING CREDIT AGREEMENT, LONG-TERM DEBT, CAPITAL LEASE
     OBLIGATIONS AND NOTES PAYABLE TO STOCKHOLDERS

Borrowings Under Revolving Credit Agreement

          At March 29, 1996, TSG was able to borrow up to a maximum of $9
million under term and installment notes and a revolving credit agreement under
the terms of a Loan and Security Agreement (the "Loan Agreement") between TSG
and its bank. Indebtedness under the Loan Agreement at March 29, 1996 included
$2,525 outstanding under term and installment notes and $1,094 outstanding under
the revolving credit agreement.

          At March 28, 1997 and June 27, 1997, TSG was able to borrow up to a
maximum of $9 million under the revolving credit agreement. At March 28, 1997
and June 27, 1997, TSG had outstanding debt of $3,811 and $2,400 (unaudited),
respectively, under the revolving credit agreement.
 
          Amounts borrowed under the Loan Agreement are collateralized by
substantially all assets of TSG including accounts receivable, inventories and
property and equipment. The borrowing limit under the revolving credit agreement
is based upon specified percentages applied to the value of collateral,
consisting of accounts receivable and inventories (less amounts outstanding
under a $2.2 million term note at March 29, 1996), and varies based upon changes
in the collateral value. Interest is payable monthly based upon the greater of
the actual outstanding debt balances or $4 million at a variable rate per annum
equal to 1.5% above a base rate quoted by Citibank (8.25% March 29, 1996 and
8.50% at March 28, 1997). The Loan Agreement is renewable annually for one year
periods unless terminated by the bank upon an occurrence of an event of default
or by TSG upon at least 90 days notice. TSG has agreed to pay termination fees
of up to 2% of the average monthly borrowings or the minimum loan amount ($4
million), whichever is greater, if the Loan Agreement is terminated on the date
other than an anniversary date.
 
          The Loan Agreement contains conditions and covenants that prevent TSG
from engaging in certain transactions without the consent of the bank, including
merging or consolidating, payment of subordinated stockholder debt obligations,
declaration or payment of dividends and disposition of assets, among others.
Additionally, the Loan Agreement requires TSG to comply with specific financial
covenants, including covenants with respect to cash flow, working capital and
net worth. Noncompliance with any of these conditions and covenants or the
occurrence of any other event of default, if not waived or corrected, could
accelerate the maturity of the borrowings outstanding under the Loan Agreement.
TSG was in compliance with the covenants and conditions contained in the Loan
Agreement at March 29, 1996 and March 28, 1997.
 
          Pursuant to an amendment to the Loan Agreement on October 31, 1994,
$2.2 million of debt outstanding under the revolving credit agreement was
converted into a term note payable on November 30, 1997.

                                      C-13
<PAGE>
 
In addition, the term of the Loan Agreement was extended from May 31, 1995 to
November 30, 1997, and the interest rate on amounts borrowed under the terms of
the Loan Agreement was reduced by .75%. Proceeds of $2,569 pursuant to
subordinated promissory notes dated October 31, 1994 issued to stockholders were
used to retire debt outstanding under the revolving credit agreement. After such
repayment, the initial principal balance outstanding under the $2.2 million term
note on October 31, 1994 amounted to $1,292. Between October 31, 1994 and March
31, 1995, TSG borrowed the balance available under the $2.2 million term note of
$908.
 
          Pursuant to a June 9, 1994 amendment to the Loan Agreement, the
aggregate principal obligation under an installment note was decreased from $500
to $465, and TSG borrowed an additional $402. The expiration date of the Loan
Agreement and the due date of the term and installment notes were extended from
February 28, 1995 to May 31, 1995. The monthly principal payment under the
installment note was increased from $21 to $25. This note was repaid during the
year ended March 29, 1996.
 
          In May 1996, TSG completed an initial public offering of equity
securities (see Note 9). A portion of the proceeds of the initial public
offering were used to repay TSG's then outstanding indebtedness under the Loan
Agreement. Accordingly, TSG classified $1,094 of indebtedness outstanding under
the revolving credit facility as a long-term obligation at March 29, 1996.

Long-Term Debt and Capital Lease Obligations

          Long-term debt and capital lease obligations payable at March 29, 1996

</TABLE>


          At March 31, 1995, TSG had outstanding indebtedness of $203 pursuant
to 10% interest bearing promissory notes payable to a company affiliated with
certain officers and employees of TSG. Outstanding indebtedness under these
promissory notes was paid in full during the year ended March 29, 1996. Interest
paid pursuant to these notes during the years ended March 31, 1995 and March 29,
1996 aggregated $49 and $9, respectively. On November 9, 1994, TSG executed a
non-interest bearing promissory note in the principal amount of $207
representing unpaid royalties at October 31, 1994 due to TSG affiliated with
certain of TSG's officers and employees. The note, payable in nineteen equal
monthly installments of $11 commencing on December 11, 1994, had an outstanding
balance of $33 at March 29, 1996. This note was paid in full during the year
ended March 28, 1997.

          In May 1996, TSG completed an initial public offering of equity
securities (see Note 9). A portion of the proceeds of the initial public
offering were used to repay TSG's then outstanding indebtedness under the Loan
Agreement. Accordingly, TSG classified indebtedness outstanding under the $2.2
million term note and $310 of indebtedness then outstanding under the $650 term
note as long-term obligations at March 29, 1996.

          During the year ended March 28, 1997, TSG assigned its capital lease
obligation with respect to a one hundred thousand square foot manufacturing
facility located in Paducah, Kentucky to an unaffiliated third

                                      C-14

party.  Accordingly, TSG recorded the retirement of the capital lease obligation
with a then outstanding balance of $933 (see Note 5) during the year ended March
28, 1997.

Notes Payable to Stockholders

          On June 9, 1994, TSG borrowed $400 from its preferred stockholders and
issued a subordinated master promissory note payable on demand bearing interest
at a rate of 10% per annum.  This note, accrued interest and preference fees,
which when added to accruing interest would equal 5% of the outstanding
principal amount for each month that the note was outstanding, became due upon
the Acquisition.  Accordingly, the subordinated master promissory note, together
with accrued interest and preference fees from the date of issuance aggregating
$96 were retired on October 31, 1994.

          On October 31, 1994, TSG entered into an Investment Agreement with the
investors.  Under the terms of the Investment Agreement, TSG borrowed $2.8
million from the investors and issued 10% interest bearing subordinated
promissory notes due November 1, 1999.  During the year ended March 28, 1997,
TSG repaid the subordinated promissory notes with a portion of the proceeds from
its initial public offering (see Note 9).  Interest accrued under the terms of
the subordinated promissory notes was payable semi-annually beginning May 1,

interest with respect to the subordinated notes of $280 and $152, respectively.
At March 29, 1996, interest accrued under the terms of the subordinated
promissory notes aggregated $117.

9.   STOCKHOLDERS' EQUITY

Preferred Stock

          TSG is authorized, under its Certificate of Incorporation as amended
on October 31, 1994, to issue up to 100,000 shares of preferred stock, $100 par
value, in one or more series or other designations determined by the Board of
Directors ("Board") of TSG. The Board is authorized to determine, as to any
particular series of preferred stock: the dividend rights, including annual
dividend rates and whether the dividends shall be cumulative

                                      C-15
<PAGE>
 
or non-cumulative; redemption provisions; per-share liquidation preferences;
voting powers; conversion terms; and any other rights or preferences.  No
dividends may be paid or declared on TSG's common stock or on any other class of
stock ranking junior to the preferred stock, nor shall any shares of common
stock or any other class of stock ranking junior to the preferred stock be
purchased, retired or otherwise acquired by TSG unless all dividends accrued and
payable on preferred shares and all amounts required to retire the preferred
shares have been paid out of assets legally available for the payment of such
obligations.

          At March 28, 1997, no preferred stock had been issued, nor has the
Board designated any series of preferred stock for issuance or determined any
related rights or preferences.

          In connection with the Acquisition, the then outstanding shares of
TSG's Series A, Series B, Series C and Series E preferred stock were cancelled.
The Series A, Series B, Series C and Series E preferred stock had per-share
liquidation preferences of $15, $5, $2.50 and $2.50, respectively, plus declared
and unpaid dividends. The aggregate liquidation preference of the preferred
stock in order of priority were as follows: Series E - $750; Series C - $5,852;
Series B - $1,500; and Series A - $4,600. The shares of preferred stock were
convertible into an equal number of shares of common stock, subject to certain
anti-dilution provisions. Shares of Series A, Series B and Series C preferred
stock were convertible into voting common stock. Shares of Series E preferred
stock were convertible into non-voting common stock. Series A, Series B and
Series C preferred shares had voting rights equal to the number of shares of
common stock which would have been received upon conversion to common shares.
The Series E preferred stock had no voting rights.

          TSG could not, without the consent of stipulated percentages of
holders of the applicable series of preferred stock, authorize or create any
class or series of capital stock ranking, either as to payment of dividends or
distribution of assets, prior to or on a parity with such series of convertible
preferred stock or alter or change the powers, preferences or rights of such
series of convertible preferred stock. Further, TSG could not sell shares of
capital stock ranking, either as to payment of dividends or distribution of
assets, prior to or on parity with those of convertible preferred stock at
prices less than the conversion prices or convertible into common stock at
prices less than the conversion prices of convertible preferred stock without
such consent(s).

Common Stock

          TSG is authorized, under its Certificate of Incorporation as amended
on October 31, 1994, to issue up to 10,000,000 shares of common stock, $.01 par
value. As described in Note 1, TSG issued 3.5 million shares of common stock on
October 31, 1994 in accordance with the terms of an Investment Agreement between
TSG, Wexford and certain former investors.

          Holders of voting common stock are entitled to one vote per share on
all matters to be voted on by the stockholders. No dividends may be paid or
declared on TSG's common stock until all dividends accrued and payable on
preferred shares outstanding have been paid.

          In connection with the Acquisition, the then outstanding shares of
TSG's common stock were cancelled. Prior to the Acquisition, TSG was authorized
to issue 11,100,000 shares of common stock, $.05 par value.

Initial Public Offering and Common Stock Purchase Warrants

          In May 1996, TSG completed an initial public offering of 1,150,000
units (the "Units"), each Unit consisting of one share of common stock and one
redeemable warrant ("Redeemable Warrant") at a price of $9.00 per Unit for gross
proceeds of $10,350. In connection with the offering, TSG issued warrants to the
underwriters to purchase 100,000 shares of common stock (the "Underwriter
Warrants") for nominal consideration. Net proceeds received by TSG, after
underwriting discounts and expenses of $1,232 and other expenses of $825,
amounted to $8,293. At March 29, 1996, TSG had incurred, and deferred as other
assets, offering expenses of $338. Accordingly, net proceeds during the year
ended March 28, 1997 amounted to $8,632.

          Two Redeemable Warrants entitle the holder thereof to purchase one
share of common stock at an exercise price of $11.00 per share. Unless the
Redeemable Warrants are redeemed, the Redeemable Warrants

                                      C-16
<PAGE>
 
may be exercised at any time beginning on May 10, 1996 and ending May 9, 1999,
at which time the Redeemable Warrants will expire.  Beginning on February 10,
1997, the Redeemable Warrants are redeemable by TSG at its option, as a whole
and not in part, at $.05 per Redeemable Warrant on 30 days' prior written
notice, provided that the average closing price of the common stock equals or
exceeds $12.00 per share for 20 consecutive trading days ending within five days
prior to the date of the notice of redemption.  The Redeemable Warrants will be
entitled to the benefit of adjustments in the exercise price and in the number
of shares of common stock deliverable upon the exercise thereof upon the
occurrence of certain events, including a stock dividend, stock split or similar
reorganization.

          The Underwriter Warrants are initially exercisable at a price of
$10.80 per share of common stock. The Underwriter Warrants contain anti-dilution
provisions providing for adjustments of the number of warrants and exercise
price under certain circumstances. The Underwriter Warrants grant to the holders
thereof certain rights of registration of the securities issuable upon exercise
of the Underwriter Warrants. The Underwriter Warrants may be exercised at any
time beginning on May 10, 1997 and ending May 9, 2001, at which time the
Underwriter Warrants will expire.

          As of October 31, 1994, TSG had outstanding warrants to purchase an
aggregate of 312,000 shares of Series C preferred stock at a price of $2.50 per
share.  These warrants were cancelled upon consummation of the Acquisition.
Generally, the warrants were exercisable for five-year periods beginning either
on the issuance date or one year thereafter, and expired on various dates
through March 31, 1996.

          On May 23, 1995, TSG issued a warrant to one of its contract
manufacturers to purchase 40,000 shares of common stock, $.01 par value, at a
price of $4.00 per share in return for the extension of credit under the terms
of a manufacturing agreement between TSG and the contract manufacturer.  On June
17, 1996, the warrant was exercised and TSG issued 40,000 shares of common stock
for aggregate proceeds of $160.

Stock Options

          On November 1, 1994, TSG's Board of Directors adopted the 1994 Omnibus
Stock Plan (the "Stock Plan").  The Stock Plan provides the Board or a committee
of the Board with the authority to grant to officers and employees of TSG
incentive stock options within the meaning of Section 422A of the Internal
Revenue Code and to grant to directors, officers, employees and consultants of
TSG non-qualified stock options and restricted stock which do not qualify as
incentive stock options. An aggregate of 635,000 shares of TSG's common stock
may be issued under the Stock Plan. The maximum number of shares with respect to
which options may be granted to any one employee may not exceed 300,000 shares.
The Board's authority to grant options under the Stock Plan expires on November
1, 2004. The Stock Plan is administered by a Stock Plans Committee consisting of
members appointed by the Board.

          The Board has the authority to determine option periods, the number of
shares of common stock subject to options granted and such other terms and
conditions under which options may be exercised.  The Board also has the
authority to determine at which times options or restricted stock may be
granted, the purchase price of restricted stock, whether an option shall be an
incentive stock option or a non-qualified option, whether restrictions such as
repurchase rights are to be imposed on shares subject to options and restricted
stock, and the nature of such restrictions.  The per-share option price of
incentive stock options granted under the Stock Plan shall not be less than the
per-share fair market value, as determined by the Board, of TSG's common stock
as of the date of grant, or 110% of the per-share market value with respect to
incentive stock options granted to employees owning 10% or more of the total
combined voting power of all classes of TSG's stock.  Option periods shall not
exceed ten years from the date options are granted, or five years with respect
to incentive stock options to employees owning 10% or more of the total voting
power of all classes of TSG's stock.  Options granted under the Stock Plan
generally expire 60 days after termination of employment or at the end of the
option period stipulated by the Board in the option agreement, whichever is
earlier.

          The Board has the authority to accelerate the date of exercise of an
option or any installment thereof, unless, in the case of incentive stock
options, such acceleration would violate the annual vesting limitations
contained in Section 422(d) of the Internal Revenue Code. The exercise prices of
options granted under the Stock Plan are subject to adjustment upon any
subdivision, combination, merger, splits, split-up, liquidation, or the like,

                                      C-17
<PAGE>
 
to reflect such subdivision, combination or exchange.  The number of shares of
common stock to be received upon exercise of options granted under the Stock
Plan are subject to adjustment upon declarations of stock dividends between the
date of grant and the date of exercise of options.  Also, the number of shares
of common stock reserved for issuance under the Stock Plan shall be adjusted
upon the occurrence of such events.

          The Board may grant restricted stock under the Stock Plan pursuant to
a restricted stock agreement. The Board has the authority to determine the
number of shares of common stock to be issued and to the extent, if any, to
which they shall be issued in exchange for cash and/or other consideration.
Shares issued pursuant to restricted stock may not be sold, transferred,
pledged, or otherwise disposed of, except by the laws of descent and
distribution, or as otherwise determined by the Board for a period as determined
by the Board from the date the restricted stock is granted. TSG has the right to
repurchase restricted stock at such price as determined by the Board on the date
of grant. The repurchase rights are exercisable on such terms as determined by
the Board upon the termination of services of the grantee prior to expiration of
the restriction on transfer of the shares, failure of the grantee to pay TSG
income taxes required to be withheld in respect of the restricted stock or under
such other circumstances as the Board may determine.

          The following table summarizes the status and changes in stock options
outstanding under the Stock Plan for the five months ended March 31, 1995 and
years ended March 29, 1996 and March 28, 1997:

          Options granted and outstanding under the Stock Plan are generally
exercisable in four equal annual installments beginning on the date of grant. At
March 28, 1997, outstanding options under the Stock Plan have a weighted average
remaining contractual life of 8.17 years. At March 29, 1996 and March 28, 1997,
635,000 and 630,000 shares, respectively, were reserved for issuance under the
Stock Plan.
 
          On May 10, 1995, the Board of Directors approved the adoption of the
1995 Employee Stock Purchase Plan (the "Employee Plan"). The Employee Plan
provides the Board of Directors with the authority to grant to TSG's officers
and employees the right to purchase up to 100,000 shares of common stock at 85%
of the public market price. However, the Employee Plan did not become effective
until TSG's initial public offering. The rights granted under the Employee Plan
are exercisable for an offering period as determined by the Board of Directors,
which may not exceed 27 months. No employee may be granted an option under which
the employee's

                                      C-18
<PAGE>
 
right to purchase shares under the Employee Plan first become exercisable at a
rate in excess of $25 in fair market value (determined at the date of grant) in
any calendar year. Also, an employee may not allocate in excess of 10% of his or
her compensation for purchase of stock under the Employee Plan during any
offering period. The Stock Plans Committee of the Board of Directors administers
the Employee Plan. The Employee Plan was approved by the stockholders of TSG on
December 26, 1995. At March 29, 1996 and March 28, 1997, 100,000 and 93,240
shares of common stock, respectively, were reserved for issuance under the
Employee Plan.
 
          During the first offering period ending November 15, 1996, 6,760
shares were purchased by employees at a price of $7.65 per share. During the
second offering which commenced January 13, 1997 (and which will end on July 11,
1997), 5,930 shares are subject to purchase under the Employee Plan based on the
base compensation of participates and the per-share market price of TSG's common
stock on January 13, 1997. The actual number of shares that may be issued will
vary based upon compensation of the participants during the offering period, the
per-share market value of TSG's common stock on July 11, 1997, and the number of
participates who have not withdrawn by the July 11, 1997 end date.
 
          On May 10, 1995, the Board approved the adoption of the 1995 Non-
Employee Director Stock Option Plan (the "Director Plan"). The Director Plan
provides for the grant to directors who are not employees of TSG of options to
purchase up to 100,000 shares of common stock. The Director Plan is administered
by the Stock Plans Committee consisting of members appointed by the Board.
Pursuant to the Director Plan, each non-employee director was automatically
granted a non-qualified option to purchase 10,000 shares of common stock upon
the consummation of TSG's initial public offering on May 10, 1996. Thereafter,
on September 1 of each year, each non-employee director receives a non-qualified
option to purchase 3,000 shares of common stock. Any non-employee director who
is first appointed or elected after TSG's initial public offering will receive a
non-qualified stock option to purchase 3,000 shares of common stock upon such
appointment or election and an additional option to purchase 3,000 shares of
common stock on each anniversary of the date of his or her election, provided
that he or she is then serving as a non-employee director. Options granted upon
consummation of TSG's initial public offering became exercisable six months from
the date the offering. All other options become exercisable on the anniversary
of the date of grant. Option periods shall not exceed ten years from the date
options are granted. Options granted under the Director Plan have an exercise
price equal to the market value per share of the common stock on the date of
grant. Options granted expire 180 days after the date a director ceases to serve
as a director or 10 years from the grant date, whichever is earlier. Vesting is
accelerated in the event of a change of control of TSG.
 
          On May 10, 1996, options to purchase 30,000 shares of common stock
were automatically granted to non-employee directors at an exercise price of
$8.50 per share. On May 17, 1996, options to purchase 3,000 shares of common
stock were granted at an exercise price of $10.781 to a non-employee director
elected to the Board on that date. On September 1, 1996, options to purchase
9,000 shares of common stock were automatically granted to non-employee
directors at an exercise price of $10.812 per share. On March 14, 1997, options
to purchase 3,000 shares of common stock were granted at an exercise price of
$5.00 to a non-employee director elected to the Board on that date. At March 28,
1997 options to purchase 45,000 shares of common stock at a weighted-average

                  On October 31, 1994 upon consummation of the Acquisition,
TSG's Incentive Stock Option Plan (the "Plan") adopted by the Board of Directors
effective June 1, 1992 was cancelled. The Plan provided the Board with the
authority to grant to key employees of TSG incentive stock options to purchase
up to a maximum of 300,000 shares of TSG's common stock. Options granted under
the Plan were intended to constitute incentive stock options within the meaning
of Section 422A of the Internal Revenue Code. The Board had the authority to
determine option periods, the number of shares of common stock subject to
options granted and such other terms and conditions under which options may be
exercised. Options granted under the Plan were to expire upon termination of
employment or at the end of the option period stipulated by the Board in the
option agreement, whichever was earlier. The Plan specifically limited the
aggregate fair market value of options which could be exercised by an employee
in any one calendar year to $100. The Board's authority to grant options under
the Plan was to expire on May 31, 2002. On August 4, 1994, the Board of
Directors authorized management to grant options covering 253,500 shares of
common stock to employees. However, as of the date of cancellation of the Plan,
no options had been granted.

Stock Option Compensation

                  TSG has adopted the disclosure-only provisions of SFAS 123.
Accordingly, no compensation cost has been recognized for stock options and
purchase rights granted under TSG's plans in accordance with the requirements of
APB 25. Had compensation cost related to stock options and purchase rights
granted under TSG's plans been recognized based on the fair value of awards on
the grant dates consistent with SFAS 123, TSG would have recorded compensation
expense of $55 and $613 during the years ended March 29, 1996 and March 28,
1997.

                  The fair value of each option or right granted under TSG's
stock option and purchase plans is estimated on the date of grant using the
Black-Scholes option pricing model. The significant weighted-average

assumptions used during the years ended March 29, 1996 and March 28, 1997 to
estimate the fair values of options and rights granted under TSG's plans are
summarized in the following table.

                  Based on these assumptions, the weighted-average fair value of
each option and right granted under TSG's plans for the years ended March 29,
1996 and March 28, 1997 amounted to $2.63 and $4.70, respectively. The
weighted-average fair value of each option granted under the Stock Plan during
the years ended March 29, 1996 and March 28, 1997 was $2.63 and $5.04,
respectively. The weighted-average fair value of each option granted under the
Director Plan during the year ended March 28, 1997 was $4.53. The
weighted-average fair value of each purchase right granted under the Employee
Plan during the year ended March 28, 1997 was $1.91.

                  A comparison of TSG's net income and net income per share as
reported and on a pro forma basis had compensation cost been recorded based on

          The valuation allowance for deferred tax assets during the seven 
months ended October 30, 1994 and five months ended March 31, 1995 increased by 
$964 and $425, respectively. The valuation allowance for deferred tax assets 
during the years ended March 29, 1996 and March 28, 1997 decreased by $1,407 and
$1,531, respectively. A full valuation allowance was maintained through March 
31, 1995 because it is more likely than not that deferred tax assets will not be
realized.

          Income taxes currently payable for the years ended March 29, 1996 and 
March 28, 1997 were reduced by $455 and $72, respectively, through the 
utilization of net operating loss carryforwards. During the years ended March 
29, 1996 and March 28, 1997, TSG reduced the valuation allowance and recorded 
tax benefits of $50 and $493, respectively. Deferred tax benefits from 
utilization of net operating loss carryforwards and reductions in the valuation
allowance of $211 and $442 were allocated to reduce goodwill during the years 
ended March 29, 1996 and March 28, 1997, respectively.


          As of March 28, 1997, TSG has tax net operating loss carryforwards 
available to reduce future taxable income of approximately $14 million, which 
expire from 1998 through 2010. The utilization of such net operating loss 
carryforwards and realization of tax benefits in future years depends 
predominantly upon the recognition of taxable income. Further, the utilization 
of these carryforwards is subject to annual limitations as a result of the 
change in ownership of TSG (as described in Note 2) as defined in the Internal 
Revenue Code. The limitation approximates $210 annually and represents the value
of TSG's capital stock immediately before the date of the ownership change 
multiplied by the federal long-term tax-exempt rate in effect during the month 
the ownership change occurred. This limitation does not reduce the total amount 
of net operating losses which may be taken, but rather substantially limits the 
amount which may be used during a particular year. As a result, TSG will be 
unable to use a significant portion of its net operating loss carryforwards.


11.    RESTRUCTURING CHARGES AND CREDITS

          As a result of the Acquisition and additional financing described in
Note 2, TSG was able to settle certain severance obligations under terminated
employment contracts and negotiate the termination of certain non-cancelable
lease obligations with respect to facilities closed in connection with a
restructuring initiated in fiscal 1994. The severance and lease obligations were
settled on terms more favorable than previously estimated, which resulted in the
recognition of restructuring credits of $249 and $274, respectively, during the
seven months ended October 30, 1994. In addition, TSG revised its estimate of
certain other severance obligations, and recorded additional restructuring
credits of $11. Accordingly, during the seven months ended October 30, 1994, TSG
realized net restructuring credits of $534.

          During the year ended March 28, 1997, TSG approved and initiated a
consolidation plan intended to augment its on-going productivity and quality
improvement programs. The consolidation plan provided for the closure of TSG's
Kentucky manufacturing facility, the closure of TSG's Georgia corporate office
facility, the consolidation of repair, refurbishment and conversion service
operations into TSG's Virginia facility and the consolidation of corporate
activities and product assembly operations into a new Georgia facility. In
connection with this plan, TSG recorded restructuring charges of $63 during the
year ended March 28, 1997. These restructuring charges consist of severance
obligations and losses related to abandonment of assets. Relocation expenses and
other incremental costs incurred in connection with the consolidation and
charged to operations during the year ended March 28, 1997 approximated $350.

12.    PROFIT SHARING RETIREMENT PLAN

          On January 1, 1995, TSG adopted a 401(k) retirement and profit sharing
plan. Eligible employees of TSG who are 21 years of age with one or more years
of service and who are not covered by collective bargaining agreements may elect
to participate in the plan. Employees who elect to become participants in the
plan may contribute up to 15% of their compensation to the plan up to a maximum
dollar limit established by law. TSG may also contribute to the plan at the
discretion of the Board of Directors. Contributions by TSG may consist of
matching contributions, discretionary profit sharing contributions and other
special contributions. During the five months ended March 31, 1995 and years
ended March 29, 1996 and March 28, 1997, TSG accrued profit sharing and
retirement expense of $2, $16 and $27, respectively, pursuant to discretionary
matching contributions authorized by the Board of Directors. Contributions to
the plan funded by TSG during the years ended March 29, 1996 and March 28, 1997
amounted to $14 and $26, respectively. Participants are 100% vested with respect
to their compensation contributions to the plan. Vesting in Company
discretionary contributions begins at 20% after one year of service and
increases by 20% annually each year until full (100%) vesting upon five years of
service. The plan pays retirement benefits based on the participant's vested
account balance. Benefit distributions are generally available upon a
participant's death, disability or retirement. Participants generally qualify to
receive retirement benefits upon reaching the age of 65. Early retirees
generally qualify for benefits provided they have reached age 55 and have
completed 5 years of service with TSG. Benefits are payable in lump sums equal
to 100% of the participant's account balance.

          Rental expense approximated $257 for the seven months ended October
30, 1994, $176 for the five months ended March 31, 1995, $376, net of sublease
income of approximately $18, for year ended March 29, 1996 and $323, net of
sublease income of approximately $45, for the year ended March 28, 1997.

Litigation, Disputes and Environmental Matters

          During the seven months ended October 30, 1994, TSG settled litigation
against a supplier to recover costs and damages attributable to defective
components supplied to TSG, and realized a gain of $261, net of legal fees of
$56.
 
          Pursuant to the terms of a settlement agreement and mutual release 
dated July 3, 1996, a suit filed against TSG by a former supplier to collect
approximately $400 of unpaid obligations was dismissed with prejudice. Under the
terms of the settlement agreement, TSG paid $180 and agreed to pay an additional
$112 in six equal monthly installments of $19 commencing on August 15, 1996. As
a result of the settlement agreement, TSG realized a gain of $105 representing
the difference between unpaid obligations recorded in TSG's accounts and
aggregate settlement payments set forth in the settlement agreement. The gain is
reflected in TSG's results of operations for the year ended March 28, 1997.
 
          TSG has been involved in a dispute with a former contract manufacturer
since 1994 with respect to inventories acquired by the manufacturer for TSG's
programs, which approximate $l million, unpaid obligations of TSG of
approximately $265, and other matters including an alleged claim of lost profits
by the contract manufacturer of approximately $916 related to TSG's minimum
contract purchase commitment. TSG has alleged that the contract manufacturer
breached the agreement, is obligated to pay unpaid obligations to TSG of
approximately $125 and is obligated to TSG for lost business and expenses due to
the delivery of defective products and the termination of a significant sales
agreement. Neither party is presently pursuing the dispute. There is no
assurance, however, that the dispute will not be pursued or escalate into
litigation. Should the dispute escalate into litigation, TSG intends to defend
and pursue its positions vigorously. In the opinion of management, the ultimate
outcome of this matter will not have a material impact on TSG's financial
statements.
 
          TSG is a potentially responsible party with respect to undertaking
response actions at a facility for the treatment, storage and disposal of
hazardous substances operated by an unaffiliated party. In the opinion of
management, the ultimate outcome of this environmental action will not have a
material impact on TSG's financial statements.

Significant Customers
 
          TSG's primary customers consist of the regional bell telephone 
companies. During the seven months ended October 30, 1994, three of the regional
bell telephone companies accounted for 33%, 23% and 11% of TSG's consolidated
sales. During the five months ended March 31, 1995, four of the regional bell
telephone companies accounted for 34%, 23%, 11% and 10% of TSG's consolidated
sales. During the year ended March 29, 1996, three of the regional bell
telephone companies accounted for 47%, 17% and 24% of TSG's consolidated sales.
During the year ended March 28, 1997, three of the regional bell telephone
companies accounted for 14%, 16% and 60% of TSG's consolidated sales. Accounts
receivable at March 29, 1996 and March 28, 1997 consists primarily of amounts
due from the regional bell telephone companies.

Royalty and License Agreements
 
          Pursuant to the terms of an asset purchase agreement entered into on
January 11, 1991, TSG agreed to pay royalties equal to 3.5% of sales of
microprocessor-based components to a company affiliated with certain officers
and employees of TSG. On November 9, 1994, the royalty provisions of the
purchase agreement were amended to eliminate royalties for the period April 2,
1994 to September 30, 1994. In return, the term of the royalty obligation was
extended from December 31, 1995 to June 30, 1996. Royalty expense under this
agreement amounted to $4 during the seven months ended October 30, 1994, $94
during the five months ended March 31, 1995, $564 during the year ended March
29, 1996 and $196 during the year ended March 28, 1997.
 
          TSG has entered into a patent license agreement providing TSG with the
exclusive world-wide rights to certain algorithm software covered by a patent
application. TSG is obligated to pay license fees aggregating $200 at a rate of
$50 annually over a four year period commencing on the date the patent is
issued. Further, the agreement provides for the payment of royalties on products
incorporating the licensed software. Minimum royalties payable upon issuance of
the patent will range between $125 and $500 annually during the life of the
patent. The term of the license agreement will correspond to the expiration date
of the patent upon its issuance. As of March 28, 1997, the patent has not been
issued. Accordingly, TSG has not recorded the contingent liability in the
accompanying financial statements. Further, as of March 28, 1997, TSG has not
sold any products incorporating the licensed software or incurred any royalty
obligations under the agreement.
 
          In December 1994, TSG sold the rights to certain product software 
for an aggregate purchase price of $500. TSG received an exclusive irrevocable
perpetual right to sublicense the software in connection with the sale of
products to other customers. In return, TSG agreed to pay royalties equal to the
greater of 4.44% of sales or ten dollars per unit sold. As of March 28, 1997,
TSG has not sold any products incorporating the licensed software to other
customers or incurred any royalty obligations under the agreement TSG was
obligated to repay, three years from the date of the contract, a portion of the
purchase price up to a maximum amount of $375 depending upon the amount of
aggregate royalties paid pursuant to the agreement. However, in May 1997, TSG
entered into an agreement that terminated TSG's royalty and repayment
obligations.

Employment Contracts

          On October 31, 1994, TSG entered into an employment contract with one
of its executives that provides for minimum annual compensation of $147 through
December 31, 1996 and $160 from January 1, 1997 through December 31, 1997. The
contract provides for compensation increases at the discretion of the Board of
Directors, additional compensation in the form of bonuses based on performance,
benefits equal to those provided to other executives of TSG, reimbursement of
business expenses, travel and temporary living expenses and options to purchase
shares of TSG's common stock. The agreement provides for annual renewals
subsequent to December 31, 1997 at the option of TSG. Termination by TSG without
cause entitles the executive to receive his current salary and benefits for the
remaining term of the agreement or for a period of six months, whichever is
greater. The agreement may be terminated by the executive upon 120 days notice
effective on December 31, 1997 or thereafter.

          On October 31, 1994, TSG entered into an agreement with the Chairman
of the Board of Directors that provides for minimum annual compensation of $60
through December 31, 1997. The agreement provides for additional compensation
based on services performed not to exceed $3 per month, benefits equal to

                                      C-28
<PAGE>
 
those provided to other executives of TSG, reimbursement of business expenses
and options to purchase shares of TSG's common stock. Termination by TSG without
cause entitles the Chairman to receive his current salary and benefits for the
remaining term of the agreement or for a period of six months, whichever is
greater. The agreement may be terminated by the Chairman upon 90 days written
notice. Prior to execution of the Chairman's Agreement, the Chairman provided
consulting services, as President of Atlantic Management Associates, Inc., to
TSG during the seven months ended October 30, 1994 similar to those provided
under the Chairman's Agreement. In addition, Atlantic Management Services, Inc.
assisted TSG and its stockholders in their efforts to attract a buyer for the
equity of TSG, and received a success fee in connection with the Acquisition of
$75 representing compensation for such services. During fiscal 1995, TSG paid
Atlantic Management Associates, Inc. $43 for consulting services, excluding
expenses of $7, rendered prior to the date of the Chairman's Agreement. During
fiscal 1995, TSG paid the Chairman and Atlantic Management Associates, Inc. $30,
excluding expenses of $9, for services rendered under the terms of the
Chairman's Agreement. During the year ended March 29, 1996, TSG paid the
Chairman and Atlantic Management Associates, Inc. $66, excluding reimbursed
expenses of $9, for services rendered under the terms of the Chairman's
Agreement. During the year ended March 28, 1997, TSG paid the Chairman and
Atlantic Management Associates, Inc. $69, excluding reimbursed expenses of $11,
for services rendered under the terms of the Chairman's Agreement.

Purchase and Sales Commitments

          At March 28, 1997, TSG has outstanding purchase order commitments to
purchase approximately $5.5 million of microprocessor-based products under the
terms of a manufacturing agreement entered into in October 1994. Upon a
termination of the agreement by TSG, TSG is obligated to purchase inventories
held by the manufacturer and pay vendor cancellation and restocking charges, and
a reasonable profit thereon. In addition, TSG is obligated to pay a cancellation
penalty of up to $500 if it cancels its purchase obligation or a substantial
portion thereof. The amount of the cancellation penalty, if any, will vary
depending upon quantities purchased by TSG.
 
          In June 1997, TSG entered into an agreement that supersedes and 
terminates a December 1994 sales agreement. Under the new agreement, TSG agreed
to reduce the customers remaining purchase commitment of certain smart
processors and other components to approximately $3 million from approximately
$8 million under the former agreement and, among other things, upgrade the
customer's payphone management system. In return, the customer made a $250 cash
payment to TSG, terminated TSG's obligation to pay royalties on sales of certain
products to other customers and terminated TSG's obligation to repay $375
received from the sale of certain product software under the December 1994
agreement. The customer also agreed to make additional cash payments of $250 on
July 2, 1997, $100 on September 1, 1997, $150 on December 31, 1997 and $250 on
March 31, 1998 to TSG subject to TSG's compliance with the terms and conditions
of the agreement, including conditions with respect to product performance,
service and repair. The customer has the right to cancel the agreement upon
default by TSG. Therefore, there is no assurance that TSG will receive the
additional payments or that its will ship the products set forth in the
agreement.
 
15.    SUBSEQUENT EVENT (UNAUDITED)
 
          On August 13, 1997, TSG entered into an Agreement and Plan of Merger
with Elcotel, Inc. ("Elcotel") and Elcotel Hospitality Service, Inc. ("EHS"), a
wholly-owned subsidiary of Elcotel (the "Merger Agreement"). The Merger
Agreement provides for the merger of EHS into TSG and for TSG to be the
surviving corporation (the "Merger"). At the effective time of the Merger, each
outstanding share of TSG's common stock will be converted into and represent the
right to receive 1.05 shares of Elcotel common stock, $0.01 par value per share.
The closing of the Merger is subject to certain conditions and approvals,
including the approval of TSG's and Elcotel's stockholders.

                                    PART II
 
                    INFORMATION NOT REQUIRED IN PROSPECTUS
 
ITEM 20. INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
  Elcotel is a Delaware corporation. The Delaware General Corporation Law (the
"Delaware Law") generally provides that a director, employee, officer or agent
of a Delaware corporation who was or is a party or is threatened to be made a
party to any threatened, pending or completed action, suit or proceeding,
whether civil, criminal, administrative or investigative, may be indemnified
against liability, expenses (including attorneys' fees), judgments, fines and
amounts paid in settlement actually and reasonably incurred by such person in
connection with such proceeding (other than in a proceeding by or in the right
of the corporation), provided such person acted in good faith and in a manner
such person reasonably believed to be in, or at least not opposed to, the best
interests of the corporation, and, with respect to any criminal proceeding,
had no reasonable cause to believe the conduct was unlawful. For actions or
suits brought by or in the right of the corporation, the Delaware Law provides
that a director, employee, officer or agent of a Delaware corporation may be
indemnified against expenses (including attorneys' fees) as incurred by such
person in connection with such proceeding if such person acted in good faith
and in a manner such person reasonably believed to be in, or at least not
opposed to, the best interests of the corporation, except that if such person
is adjudged to be liable to the corporation, such person can be indemnified if
and only to the extent that a court determines that despite the adjudication
of liability, in view of all the circumstances of the case, such person is
fairly and reasonably entitled to indemnity for such expenses as the court
deems proper.
 
  The Delaware Law provides that a corporation may include, in its articles or
certificate of incorporation, a provision which limits or eliminates the
personal liability of a director to the corporation or its stockholders for
monetary damages for such persons's conduct as a director, provided that such
provision may not so limit a director's liability (i) for a breach of his or
her duty of loyalty to the corporation or its stockholders; (ii) for acts or
omissions not in good faith or involving intentional misconduct or a knowing
violation of law; (iii) for unlawful payments of dividends, certain stock
repurchases or redemptions; or (iv) for any transaction from which the
director derived an improper personal benefit. The Elcotel Certificate of
Incorporation so limits the personal liability of directors to the fullest
extent permitted under the Delaware Law. The Delaware Law further provides
that where a director, officer, employee or agent of a corporation has been
successful on the merits or otherwise in defense of any action, suit or
proceeding for which indemnification is permissible, or in defense of any
claim, issue or matter related thereto, he will be indemnified against
expenses (including attorneys' fees) actually and reasonably incurred by him
in connection therewith.

  (a) The exhibits to this registration statement on Form S-4 (together with
all amendments, supplements and exhibits thereto, the "Registration
Statement") are listed in the Exhibit Index hereto and are incorporated herein
by reference.

the fiscal year ended March 31, 1997, which is incorporated herein by
reference.
 
  (c) The opinion of Murray, Devine & Co. is included in Part I as Annex B to
the Joint Proxy Statement-Prospectus included in this Registration Statement
and is incorporated herein by reference.
 
ITEM 22. UNDERTAKINGS.
 
  (a) The undersigned Registrant hereby undertakes as follows:
 
    (i) To file, during any period in which offers or sales are being made, a
  post-effective amendment to this Registration Statement:
 
      A. to include any prospectus required by Section 10(a)(3) of the
    Securities Act of 1933 (the "1933 Act");
 
                                     II-1
<PAGE>
 
      B. to reflect in the prospectus any facts or events arising after the
    effective date of this Registration Statement (or the most recent post-
    effective amendment thereof) which, individually or in the aggregate,
    represent a fundamental change in the information set forth in this
    Registration Statement; and
 
      C. to include any material information with respect to the plan of
    distribution not previously disclosed in this Registration Statement or
    any material change to such information in this Registration Statement.
 
    (ii) that, for the purpose of determining any liability under the 1933
  Act, each such post-effective amendment shall be deemed to be a new
  registration statement relating to the securities offered therein, and the
  offering of such securities at that time shall be deemed to be the initial
  bona fide offering thereof; and
 
    (iii) to remove from registration by means of a post-effective amendment
  any of the securities being registered which remain unsold at the
  termination of the offering.
 
  (b) The undersigned Registrant hereby undertakes that, for purposes of
determining any liability under the 1933 Act, each filing of the Registrant's
annual report pursuant to Section 13(a) or Section 15(d) of the 1934 Act that
is incorporated by reference in this Registration Statement shall be deemed to
be a new registration statement relating to the securities offered therein,
and the offering of such securities at that time shall be deemed to be the
initial bona fide offering thereof.
 
  (c) The undersigned Registrant hereby undertakes that, prior to any public
reoffering of the securities registered hereunder through the use of a
prospectus which is a part of this Registration Statement, by any person or
party who is deemed to be an underwriter within the meaning of Rule 145(c),
the issuer undertakes that such reoffering prospectus shall contain the
information called for by the applicable registration form with respect to
reofferings by persons who may be deemed underwriters, in addition to the
information called for by the other items of the applicable form.
 
  (d) The undersigned Registrant hereby undertakes that every prospectus: (i)
that is filed pursuant to the immediately preceding paragraph (c), or (ii)
that purports to meet the requirements of Section 10(a)(3) of the 1933 Act and
is used in connection with an offering of securities subject to Rule 415, will
be filed as a part of an amendment to the Registration Statement and will not
be used until such amendment is effective, and that, for purposes of
determining any liability under the 1933 Act, each such post-effective
amendment shall be deemed to be a new registration statement relating to the
securities offered therein, and the offering of such securities at that time
shall be deemed to be the initial bona fide offering thereof.
 
  (e) Insofar as indemnification for liabilities arising under the 1933 Act
may be permitted to directors, officers and controlling persons of the
Registrant pursuant to Item 20 of this Registration Statement, or otherwise,
the Registrant has been advised that in the opinion of the Securities and
Exchange Commission such indemnification is against public policy as expressed
in the 1933 Act and is, therefore, unenforceable. In the event that a claim
for indemnification against such liabilities (other than the payment by the
Registrant of expenses incurred or paid by a director, officer or controlling
person of the Registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the Registrant shall, unless
in the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the 1933
Act and shall be governed by the final adjudication of such issue.
 
  (f) The undersigned Registrant hereby undertakes to respond to requests for
information that is incorporated by reference into the Joint Proxy Statement-
Prospectus pursuant to Items 4, 10(b), 11 or 13 of this Form, within one
business day of receipt of such request, and to send the incorporated
documents by first-class mail or other equally prompt means. This includes
information contained in documents filed subsequent to the effective date of
the Registration Statement through the date of responding to the request.
 
  (g) The undersigned Registrant hereby undertakes to supply by means of a
post-effective amendment all information concerning a transaction, and the
company being acquired involved therein, that was not the subject of and
included in the Registration Statement when it became effective.

Gentlemen:

"Company"), in connection with the preparation and filing by the Company with 
the Securities and Exchange Commission of a Registration Statement on Form S-4
(the "Registration Statement") under the Securities Act of 1933, as amended, 
relating to the proposed issuance of up to 5,753,584 shares of Common Stock of 
the Company (the "Shares") and warrants to purchase 708,750 shares of Common 
Stock of the Company (the "Warrants") pursuant to a merger between Technology 
Service Group, Inc. and Elcotel Hospitality Service, Inc., a wholly-owned 
subsidiary of the Company (the "Merger").

Re:  Merger of Elcotel Hospitality Service, Inc.,
     a Wholly-Owned Subsidiary of
     Elcotel, Inc., into Technology Service Group, Inc.
     -------------------------------------------------

Ladies and Gentlemen:

               We have acted as tax counsel to Technology Service Group, Inc., a
Delaware corporation ("TSG"), in connection with the proposed merger (the 
"Merger") with and into TSG of Elcotel Hospitality Service, Inc. ("Merger 
Subsidiary"), a Delaware corporation and a wholly-owned subsidiary of Elcotel, 
Inc., a Delaware corporation ("Elcotel"), pursuant to the terms of the Agreement
and Plan of Merger dated as of August 13, 1997 by and among TSG, Elcotel and 
Merger Subsidiary (the "Agreement") as described in the Registration Statement 
on Form S-4 to be filed by Elcotel with the Securities and Exchange Commission 
today (the "Registration Statement"). These opinions are being rendered pursuant
to your request. All capitalized terms, unless otherwise specified, have the 
meaning assigned to them in the Registration Statement.

               In connection with these opinions, we have examined and are 
familiar with originals or copies, certified or otherwise identified to our 
satisfaction, of (i) the Agreement, (ii) the shareholder certificates signed by 
TSG shareholders holding approximately 52% of the outstanding TSG Common Stock 
on the date of the Merger (the "Shareholder Certificates"), (iii) the 
Registration Statement and (iv) those other documents as we have deemed 
necessary or appropriate in order to enable us to render the opinions below. In 
our examination, we have assumed the genuineness of all signatures, the legal 
capacity of all natural persons, the authenticity of all documents submitted to 
us as originals, the conformity to original documents of all documents submitted
to us as certified, conformed or photostatic copies and the authenticity of the 
originals of those copies. In rendering the opinions set forth below, we have 
relied upon certain written representations and covenants of TSG and Elcotel 
(and assumed the accuracy of their knowledge with respect to the relevant facts)
and on the Shareholder Certificates, all of which are annexed hereto.

        In rendering our opinion as, we have considered the applicable
provisions of the Internal Revenue Code of 1986, as amended (the "Code"),
Treasury regulations, pertinent judicial authorities, interpretive rulings of
the Internal Revenue Service and those other authorities as we have considered
relevant.

        Based upon and subject to the foregoing, it is our opinion that under 
current law the Merger will constitute a reorganization within the meaning of 
section 368(a) of the Code, and TSG, Elcotel and Merger Subsidiary each will be 
a party to the reorganization within the meaning of section 368(b) of the Code.

        As a reorganization, the Merger will have the following Federal income 
tax consequences:

        1.    A TSG shareholder will not recognize gain or loss on the exchange 
of a share of TSG Common Stock for a share of Elcotel Common Stock pursuant to 
the Merger.

        2.    The basis of a TSG shareholder in a share of Elcotel Common Stock 
received pursuant to the Merger will be equal to his basis in the share of TSG 
Common Stock surrendered in exchange therefor.

        3.    The holding period of a TSG shareholder in a share of Elcotel 
Common Stock received pursuant to the Merger will include his holding period for
the share of TSG Common Stock surrendered in exchange therefor, provided he held
that share of TSG Common Stock as a capital asset at the Effective Time.

        4.    Elcotel, Merger Subsidiary and TSG will not recognize gain or loss
as a result of the Merger.

              Except as set forth above, we express no opinion as to the tax 
consequences to any party, whether Federal, state, local or foreign, of the 
Merger or of any transactions related to the Merger or contemplated by the 
Agreement or described in the Registration Statement. These opinions are being 
furnished only to you in connection with the Merger and are solely for your 
benefit in connection therewith any may not be used or relied upon for any other
purpose and may not be circulated, quoted or otherwise referred to for any other
purpose without our express written consent.

                                        Sincerely,

                                        /s/ Greenberg, Traurig, Hoffman,

            Bonus calculated for the period from the beginning of the fiscal

            complete fiscal year.

       (ii) If Mr. Bisceglia shall resign from the Company's employ, no
            Incentive Bonus shall be payable with respect to the fiscal year in

            provided herein, or for any subsequent fiscal year.

            defined as the net income attributable to TSG's operations
            determined in accordance with generally accepted accounting
            principles, consistently applied, before payment or provision for
            federal or state income or franchise taxes, and excluding (a) any
            effects of the Merger on TSG's operations; (b)any amortization of
            goodwill or other intangibles and depreciation; (c) interest
            charges; (d) any gains or losses arising from the revaluation of

            consummation of the Merger; and (d) charges or allocations by the
            Company or an affiliated company except to the extent that such
            charges are for items of expense that, had they not been paid by the
            Company or a related entity, would have been paid by the Company
            (e.g. insurance premiums

                           Vincent C. Bisceglia Employment Agreement - continued

            and interest on working capital borrowings). For purposes of the

       (ii) The words "fiscal year" and "fiscal month" shall refer to the fiscal

            In the event that the fiscal year or month of the Company is changed
            for any reason, an equitable adjustment shall be made so that no
            portion of the Incentive Bonus that would otherwise have been
            payable hereunder shall by reason of such change become not payable.

2. Stock Option:  On the Commencement Date, the Company shall grant to Mr.
   Bisceglia an option to purchase fifty thousand (50,000) shares of the
   Company's common stock under the Company's Stock Option Plan at a purchase
   price per share equal to the closing per-share market value of the Company's
   common stock of the Company on such date.

   (a)  Vesting. The option shall become exercisable as to twenty-five percent
        (25%) of the shares one year after the date of the grant, and an
        additional twenty-five percent (25%) on each of the second, third and
        fourth anniversaries of the grant date, and shall terminate on the fifth
        anniversary of the grant date.

   (b)  Registration of Sale of Option Shares. The Company shall use its best
        efforts to register the sale of the option shares to Mr. Bisceglia on
        Securities and Exchange Commission Form S-8 before or as soon as
        practicable after the date of grant.

   (c)  Termination of Employment. The option shall continue in full force and
        effect after the termination of Mr. Bisceglia's employment in 
        accordance with the terms of the Company's 1991 Stock Option Plan.
