PART I

ITEM 2.  ACQUISITION OR DISPOSITION OF ASSETS

On March 15, 1996, PhoneTel Technologies, Inc., the Registrant (or "Company")
completed the following acquisitions:

         On November 22, 1995, the Company entered into an agreement and Plan
         of Merger to acquire the outstanding common stock of International Pay
         Phones, Inc. of South Carolina and International Pay Phones, Inc. of
         Tennessee (collectively "IPP"), companies affiliated through common
         ownership and management.  Under the terms of the Agreements, the
         Company  acquired 2,101 installed phones for a purchase price of
         $3,367,212 in cash, and 555,589 restricted shares of the Company's
         Common Stock, par value $0.01, ("Common Stock"), plus 5,453 shares of
         the Company's 14% Convertible Cumulative Redeemable Preferred Stock,
         (immediately convertible into 54,530 shares of Common Stock), plus
         warrants to purchase 117,785 shares of the Company's Common Stock at a
         nominal per share exercise price.  Additionally, the Company assumed
         approximately $1,754,000 in liabilities.  The purchase price included
         the purchase of two five year non-compete agreements, valued at
         $40,000, for two of IPP's former officers.

         On November 16, 1995, the Company entered into a Share Purchase
         Agreement with Paramount Communications Systems, Inc. ("Paramount").
         Under the terms of the Agreement, the Company acquired 2,528 installed
         phones for a cash purchase price of $9,618,553, plus 8,333 shares of
         14% Convertible Cumulative Redeemable Preferred Stock (immediately
         convertible into 83,330 shares of Common Stock), plus warrants to
         purchase 179,996 shares of the Company's Common Stock at a nominal per
         share exercise price.  Additionally the Company assumed approximately
         $733,000 in liabilities.  The purchase price included a five year
         consulting and non-compete agreement, valued at $50,000 for one of
         Paramount's former officers.

The assets of IPP and Paramount consisted of 4,626 pay telephones installed on
locations, together with enclosures, inventory of uninstalled pay telephones,
parts, vehicles, computers and contracts pursuant to which the acquired pay
telephones are installed on property owned by others.  The acquisitions of IPP
and Paramount will be accounted for using the purchase method and, accordingly,
the purchase price will be allocated to the net assets, based on their
estimated fair values.


ITEM 5. OTHER EVENTS

CHANGES IN STOCKHOLDERS' EQUITY

Subsequent to December 31, 1995, the Company created three new classes of
preferred stock: (i) Series A Special Convertible Preferred Stock, $0.20 par
value, 250,000 authorized shares, immediately convertible into 20 shares of
Common Stock, and non-voting, ("Series A Preferred"); (ii) Series B Special
Convertible Preferred Stock, $0.20 par value, 250,000 authorized shares,
immediately convertible into 20 shares of Common Stock, and non-voting ("Series
B Preferred"); and (iii) 14% Convertible Cumulative Redeemable Preferred Stock,
without par value, $60 Stated Value, non-voting, June 30, 2000, mandatory
redemption date at a redemption price of $60 per share, 200,000 authorized
shares, and immediately convertible into 10 shares of Common Stock ("14%
Preferred").

CHANGES IN LONG-TERM DEBT

In a transaction consummated on March 15, 1996, the Company borrowed additional
funds of $30,530,954 (out of a total credit facility commitment of $37,250,000)
from Internationale Nederlanden (U.S.) Capital Corporation and one other lender
(collectively know as "ING"). The Company has available under the credit
facility $6.7 million to fund future acquisitions and for general working
capital purposes. The Company used the funds to complete the Paramount and IPP
acquisitions, repaid all outstanding long-term debt and capital lease
obligations which had a secured interest in the Company's installed phones,
redeemed certain series of Preferred Stock and paid related transaction fees.
The ING credit facility requires monthly interest payments at prime plus 5%.
Principal payments commence September 1997, with the amount of the principal
payment contingent upon numerous factors, including the borrowing base and cash
flow of the Company. All of the Company's installed phones are pledged as
collateral to the ING credit facility.

The majority of the ING credit facility (currently $29 million) can be converted
into Series B Preferred at the ratio of 833 shares for each $100,000 in
outstanding debt and interest. Additionally, ING received warrants to purchase
204,824 shares of Series A Preferred at an exercise price of $0.20 per share.
Each share of Series A Preferred and Series B Preferred is convertible into 20
shares of Common Stock. The difference between the exercise price of Series A
Preferred and the estimated fair value of the warrants on the date of grant will
be recorded as interest expense over the term of the ING credit facility. The
Company has estimated the annual non-cash interest expense to be $3,000,000.

Concurrent with the ING transaction, the Company redeemed the 10% Cumulative
Preferred, the 8% Preferred, and the 7% Preferred. The redemption price was
$1,117,371 and 34,434 shares of 14% Preferred. In the aggregate, $6,475,011 of
the Company's outstanding obligations, including portions of the purchase price
for the pending acquisitions, was liquidated by issuing 107,918 shares of 14%
Preferred.

Warrants to purchase 2,018,946 shares of Common Stock at a nominal exercise
price per share ("Nominal Value Warrants") were issued in conjunction with the
IPP and Paramount acquisitions, redemption of the 10% Cumulative Preferred, 8%
Preferred, and the 7% Preferred, and conversion of certain debt of the Company
to the 14% Preferred.

The Company has reserved 13,966,026 shares of Common Stock for issuance under
the following scenarios: (1) conversion of $29,000,000 of ING outstanding debt
into 241,667 shares of Series B Preferred Stock which is then immediately
convertible into 4,833,333 shares of Common Stock; (2) exercising of warrants to
purchase 204,824 shares of Series A Preferred Stock at $0.20 per share,
immediately convertible into 4,096,480 shares of Common Stock; (3) conversion of
107,918 shares of 14% Preferred into 1,079,179 shares of Common Stock; (4)
conversion, upon Shareholder approval, of 530,534 shares of 10% Non-Voting
Preferred into 885,992 shares of Common Stock; (5) the exercising of 2,018,946
Nominal Value Warrants; (6) the exercising of 580,351 warrants at prices ranging
from $5.70 to $15.75 per share; and (7) the exercising of 471,745 stock options
at prices ranging from $3.00 to $19.50 per share.

International Payphones, Inc.
Hilton Head Island, South Carolina


We have audited the accompanying Balance Sheets of International Payphones, Inc.
(a Tennessee corporation) as of September 30, 1995 and December 31, 1994, and
the related Statements of Earnings and Retained Earnings and Cash Flows for the
nine month period and year then ended. These financial statements are the
responsibility of the management. Our responsibility is to express an opinion on
these financial statements based on our audit.

We conducted our audit 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 audit provides a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the financial position of International Payphones, Inc.
and the results of its operations and its cash flows for the nine month period
ended September 30, 1995 and the year ended December 31, 1994 in conformity with
generally accepted accounting principles.

                       NOTES TO THE FINANCIAL STATEMENTS

                    September 30, 1995 and December 31, 1994





Note A - General

     International Payphones, Inc. is a Tennessee corporation formed in 1985 to
sale, install, lease and maintain pay telephone equipment. The majority of the
Company's operations are in the eastern region of the the state of Tennessee
where it owns approximately 500 telephones and receives pay telephone coin
income and long distance commissions. Under agreements with pay phone site
location owners, the Company collects the pay phone coin revenue and the long
distance commission income and pays a percentage of this revenue to the site
location owner each month. These agreements cover periods ranging from five to
twenty years. Approximately thirty to forty percent of the Company's revenue is
received under agreements with two long distance telecommunications companies.
These agreements are between an affiliate of the Company, Resort Hospitality
Services, and the two long distance carriers.


Note B - Property and equipment

     Property and equipment is stated at cost and is depreciated using the
straight-line method over useful lives ranging from 5 to 7 years for equipment
and vehicles and 31.5 years for leasehold improvements. Repairs and maintenance
are charged to expense when incurred and improvements which substantially
prolong the useful lives of the assets involved are capitalized and depreciated.
The cost of assets classified by major categories is as follows:

                                           1995                    1994

        Vehicles                         60,333.90               85,096.62
                                        ----------              ----------
           Total cost                   744,819.89              720,142.61

Note C - Income taxes

     The Company is an S corporation for Federal income tax purposes. As a
result, no provision for Federal income taxes is made by the Company because the
individual stockholders' report and pay Federal income tax on their allocated
percentage of the Company's net earnings. The Company does pay Tennessee state
excise tax on its net earnings at a 6% tax rate.

     There are timing differences in how items of income and expense reported on
the tax return and in the financial statements. These differences involve trade
receivables for long distance commission income which is reported as income when
earned in the financial statements but is reported as received for tax purposes.
In addition, depreciation expense is claimed under IRS Code Section 179 and
using accelerated writeoff methods for tax purposes, while the straight-line
writeoff method is used for financial reporting. State excise tax is provided
for in the financial statements as the items of income and deduction are
recognized therein regardless of when they are reported on the income tax
return. As a result of the timing differences, deferred tax liabilities of   
$6,000 and $5,100, respectively, have been accrued at September 30, 1995 and
December 31, 1994. In addition, income tax expense at September 30, 1995
includes $900 in deferred state excise taxes.

Board of Directors
International Pay Phones, Inc.
107 Dave Warlick Dr.
Lincolnton, North Carolina 28092

We have audited the accompanying balance sheet of International Pay Phones, Inc.
(a South Carolina corporation) as of December 31, 1994, and the related
statements of income and retained earnings, and cash flows for the year then
ended. These financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on this financial
statement based on our audit.

We conducted our audit 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 balance sheet. 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 audit provides a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the financial position of International Pay Phones, Inc.
as of December 31, 1994, and the results of its operations and its cash flows
for the year then ended in conformity with generally accepted accounting
principles.

                         NOTES TO FINANCIAL STATEMENTS

                        December 31, 1994, 1993 and 1992



(1)  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     (a) THE COMPANY

         Paramount Communications Systems, Inc. (the "Company"), a Florida
         corporation, was formed in March, 1987 as a result of the deregulation
         of the telephone industry. The Company is a Subchapter S corporation in
         the business of installing, maintaining and operating pay telephones
         throughout South Florida.


     (b) CASH AND CASH EQUIVALENTS

         The Company considers all highly liquid investments with an original
         maturity of three months or less to be cash equivalents.

     (c) PROPERTY AND EQUIPMENT

         Property and equipment are stated at cost. Depreciation and
         amortization on property and equipment are calculated on a
         straight-line basis over five years, the estimated useful lives of the
         assets.

     (d) INTANGIBLE ASSETS

         Intangible assets consist of non-compete agreements and location
         contracts. The non-compete agreements are being amortized on a
         straight-line basis over their duration (five years) and expire through
         July, 1998. The location contracts are amortized over two and one-half
         years and expire through June, 1995.

     (e) RECOGNITION OF REVENUE

         Revenues from coin calls and non-coin calls are recognized as calls are
         made. When revenue on a telephone call is recorded, an expense is also
         recorded for fees associated with the call. Revenue from the telephone
         service agreement is recognized in the month of service.

     (f) INCOME TAXES

         The Company is a Subchapter S corporation. As such, no provision is
         made for income taxes as income or loss is included in the tax returns
         of the shareholders.

     (g) CONCENTRATIONS OF CREDIT AND BUSINESS RISK

         Receivables have a significant concentration of credit risk in the
         telecommunications industry. In addition, receivables are generated by
         the Company's pay telephones located in the state of Florida. No single
         customer accounted for more than 5% of the Company's sales.


                                                                     (Continued)

                                  (ii)  The Consideration shall be decreased by
         the amount owing in respect of any telephone bills received by the
         Company on or before the Closing Date which are due prior to the
         Closing Date but not paid by the Company or Sellers on or before the
         Closing Date.
                                  (iii)  The Consideration shall be increased
         by the excess of (A) the amount accrued as of the Closing Date as
         receivables from AT&T, Opticon, and third and fourth quarter APCC (but
         only to the extent such amount is received by the Company within 150

                                  (iv)  The Consideration shall be decreased by
         the amount of all indebtedness or other Liabilities relating to the

(but in any event not more than 150 days after the Closing Date), the Parent
shall cause to be prepared and delivered to Seller Representative and the
Escrow Agent a schedule (the "Adjustment Schedule") which shows, as of the
Closing Date, the calculation of the Consideration as provided in Section

         objects to the Adjustment Schedule, Seller Representative and Parent

         Parent's receipt of such objections.  If Parent and Seller
         Representative are unable to resolve the matter within such 10-day
         period, they shall jointly appoint a mutually acceptable firm of
         independent certified public accountants (or, if they cannot agree on
         a mutually acceptable firm, they shall cause their respective
         accounting firms to select such firm) within five days after the end
         of such 10-day period.  The fees of such independent certified public

         deemed complete upon the earlier of (A) the eleventh (11th) day after
         Parent's delivery of the Adjustment Schedule to Seller Representative,
         unless prior to such day Seller Representative shall have notified
         Parent of a dispute in accordance with paragraph (i), and (B) the
         resolution of all disputes, pursuant to paragraph (ii).  Within two
         business days following completion of the Adjustment Schedule as

                 Sellers, the amount, if any, by which the Consideration (as
                 adjusted) exceeds the amount paid pursuant to Section 1.3(b);
                 or

provide a basis for a valid claim or acceleration under any Contract as against

accordance with the provisions of Section 7.5 or Section 7.6 hereof, such claim
and any related claims may continue to be asserted beyond such period.

all Losses asserted against, resulting to, imposed upon or incurred by any
Buyer





                                       63
<PAGE>   65
Indemnified Party, directly or indirectly, by reason of or resulting from:
                                           (i)    the breach of or any
           inaccuracy in any of the representations and warranties of
           the Sellers or the Company contained in or made pursuant to any 
           section of this Agreement, or any facts or circumstances

                                           (ii)    the breach or
           nonperformance of any covenant or agreement of the Sellers or the
           Company contained in or made pursuant to this Agreement or any
           facts or circumstances constituting such breach or nonperformance; 
           and
                                          (iii)    any and all Taxes

                        (i)    the breach of or any inaccuracy in any of the 
           representations and warranties of the Parent contained in or made

               7.5    Indemnification Procedures.
                      --------------------------
                            (a)    NOTICE.  If any legal proceeding shall be 
threatened or instituted or any claim or demand shall be asserted by any Buyer 
Indemnified Party or Seller Indemnified Party in respect of which 
indemnification may be sought under the provisions of this Agreement, the 
party seeking indemnification (the "Claiming Party") shall promptly cause 
written notice of the assertion of any such claim, demand or proceeding of





                                       65
<PAGE>   67
which it has knowledge to be forwarded to the party from whom it is claiming
indemnification (the "Indemnitor").  Such notice shall contain a reference to
the provisions hereof or of such other agreement, instrument or certificate
delivered pursuant hereto, in respect of which such claim is being made, and
shall specify, in reasonable detail, the amount of such Loss if determinable at
such time.  The Claiming Party's failure to give the Indemnitor prompt notice
shall not preclude the Claiming Party from seeking indemnification from the
Indemnitor unless the Claiming Party's failure has materially prejudiced the
Indemnitor's ability to defend the claim, demand or proceeding.
                                        (b)    THIRD PARTY CLAIMS.  If the
Claiming Party seeks indemnification from the Indemnitor as a result of a claim
or demand being made by a third party (a "Third Party Claim"), the Indemnitor
shall have the right to promptly assume the control of the defense of such
Third Party Claim, including, at its own expense, employment by it of counsel
reasonably satisfactory to the Claiming Party. The Claiming Party may, in its
sole discretion and at its own expense, employ counsel to represent it in the
defense of the Third Party Claim, and in such event counsel for the Indemnitor
shall cooperate





                                       66
<PAGE>   68
with counsel for the Claiming Party in such defense, provided that the
Indemnitor shall direct and control the defense of such Third Party Claim or
proceeding.  Except with the written consent of the Claiming Party, the
Indemnitor shall not consent to the entry of any judgment nor enter into any
settlement of such Third Party Claim which (i) does not include as an
unconditional term thereof the release of the Claiming Party from all liability
in respect of such Third Party Claim and (ii) results in the imposition on the
Claiming Party of any remedy other than money damages; provided, however, that
the Claiming Party shall not unreasonably withhold or delay its consent to the
entry of any judgment or any settlement of a Third Party Claim.  If the
Indemnitor elects not to exercise its rights to assume the defense of the Third
Party Claim, or if injunctive relief is sought which would have an adverse
effect on the Claiming Party, the Claiming Party may, but shall have no
obligation to, defend against such Third Party Claim or legal proceeding in
such manner as it may deem appropriate, and the Claiming Party may compromise
or settle such Third Party Claim and proceeding without the Indemnitor's
consent so long as the Claiming Party acts





                                       67
<PAGE>   69
in a commercially reasonable manner (without regard to the Claiming Party's
indemnification rights hereunder).  
                                        (c)    PAYMENT. After any final 
judgment or award shall have been rendered by a court, arbitration board or 
administrative agency of competent jurisdiction and the time in which to appeal
therefrom shall have expired, or a settlement shall have been consummated, or
the Claiming Party and the Indemnitor shall arrive at a mutually binding
agreement with respect to each separate matter alleged to be indemnified by the
Indemnitor hereunder, the Claiming Party shall forward to the Indemnitor notice
of any sums due and owing by it with respect to such matter (in accordance with
Section 8.10 hereof) and the Indemnitor shall pay all of the sums so owing to
the Claiming Party within 10 days after the date of such notice. 
Notwithstanding the foregoing, the obligation of Sellers to indemnify under
this Article VII shall be limited to 50% of the aggregate Consideration; such
indemnification obligation shall be satisfied 50% in cash (by wire transfer,
certified or bank cashier's check) and 50% in Parent Shares (valued at the
Stock Price).
                                        (d)    ESCROW.  To the extent that the
Escrow Amount has not been released pursuant to the Escrow Agreement, the Buyer
Indemnified Party's right to





                                       68
<PAGE>   70
indemnification and to be held harmless pursuant to Section 7.3 hereof must
first be asserted against the Escrow Amount.

Procedures:  Notice Requirements; Control Of Proceedings.
- --------------------------------------------------------
                                        (a)    If a notice of deficiency, 
proposed adjustment, adjustment, assessment, audit, examination,
suit, dispute or other claim (a "Tax Claim") shall be delivered, sent,
commenced, or initiated to or against any Buyer Indemnified Party by any taxing
authority with respect to Taxes for which the Sellers have agreed to indemnify
any Buyer Indemnified Party, Parent shall promptly notify the Sellers'
Representative in writing of the Tax Claim.  If any such Tax Claim shall be
delivered, sent, commenced or initiated to or against the Sellers by the
relevant taxing authority, the Sellers shall promptly notify Parent in writing
of such Tax Claim.
                                        (b)    The Sellers' Representative may,
upon timely notice to Parent, assume and control the defense of any such Tax
Claim at their own cost and expense and with their own counsel.  If the
Sellers' Representative elects to assume the defense of any such Tax Claim,
notwithstanding anything to the contrary contained herein, (i) the Seller's
Representative shall consult with





                                       69
<PAGE>   71
Parent and shall not enter into any settlement with respect to any such Tax
Claim without Parent's prior written consent if the effect of such settlement
would be to increase the liability for Taxes of Buyer for any taxable period;
(ii) the Sellers shall keep Parent informed of all material developments and
events relating to such Tax Claim; and (iii) at its own cost and expense,
Parent shall have the right to participate in (but not to control) the defense
of such Tax Claim.
                                        (c)    In connection with any Tax Claim
that the Sellers' Representative does not timely elect to control pursuant to
Section 7.6, such contest shall be controlled by the Parent, and the Sellers
agree to cooperate with the Parent and its affiliates in pursuing such contest.
Parent shall keep the Sellers informed of all material developments and events
relating to such Tax claim and Sellers, at their own cost and expense, shall
have the right to participate in (but not control) the defense of such Tax
claim.  Nothing contained herein shall be construed as limiting Parent's right
to indemnification under this Article VII.

Seller hereby designates and appoints the Seller Representative as its
authorized agent upon whom process may be served in any suit, proceeding or
other action against such Seller instituted by the Buyer and relating to this
Agreement.  Such designation and appointment shall, to the extent permitted by
law, be irrevocable, unless and until a successor authorized agent acceptable
to the Buyer shall have been appointed by the Sellers, such successor shall
have accepted such appointment and written notice thereof shall have been given
to the Buyer.  Each Seller further agrees that service of process upon such
authorized agent or successor shall be deemed in every respect service of
process upon such Seller in any such suit, proceeding or other action.  Each
Seller further agrees to take any and all action, including the execution and
filing of all such instruments and documents, as may be necessary to continue
such designation and appointment of such authorized agent in full force and

                                       TO
                      THE AGREEMENT AND PLAN OF MERGER
                                     AMONG
                         PHONETEL TECHNOLOGIES, INC.
                         INTERNATIONAL PAY PHONES, INC.
                                [South Carolina]
                                      AND
               THE SHAREHOLDERS OF INTERNATIONAL PAY PHONES, INC.


                 Amendment No. 1, dated as of January 16, 1996 ("Amendment No.
1"), to the Agreement and Plan of Merger, dated as of November 22, 1995 (the
"Original Agreement"), among PhoneTel Technologies, Inc., an Ohio corporation
("Parent"), International Pay Phones, Inc., a South Carolina corporation
("Company"), and the shareholders of the Company (collectively, the "Sellers").

                 Parent and Sellers entered into the Original Agreement on
November 22, 1995.  Parent and Sellers desire to amend the Original Agreement
to make the changes set forth below.

                 NOW THEREFORE, in consideration of the agreements herein set
forth and for other valuable consideration, the receipt and adequacy of which
are hereby acknowledged, Parent and Sellers covenant and agree as follows:

         1.      Alton L. Huffman is hereby added as a party to the Original
                 Agreement.  Exhibit A to the Original Agreement is hereby
                 deleted and Exhibit A attached to this Amendment No. 1 is
                 hereby substituted in its place.

         2.      The Closing as defined in Section 1.7(a) of the Original
                 Agreement shall take place on or before February 29, 1996, as
                 may be mutually agreed by Buyer and Sellers, and the term
                 "Closing Date", as defined and used in the Original Agreement,
                 shall be amended to mean the date on which the Closing
                 actually takes place.
<PAGE>   95
         3.      The term "Buyer" as used in the Original Agreement is hereby
                 deleted and replaced with the term "Parent" as defined and
                 used in the Original Agreement.

         4.      The term "Buyer" is hereby eliminated as a defined term from
                 Section 9.1 of the Original Agreement.

         5.      The following Section 1.4(c)(v) is added to the Original
                 Agreement:

                          "The Consideration shall be increased by an amount
                          equal to the Company's net operating loss, before
                          depreciation and amortization, from January 11, 1996
                          through the date of Closing as reflected on the
                          Company's income statement which shall be prepared on
                          the date of Closing in accordance with generally
                          accepted accounting practices."

         6.      Section 8.2(a) of the Original Agreement is hereby amended to
                 add the following language at the end of such Section:

                          ", and, from and after the Closing Date, Parent may
                          assign its rights hereunder to any party providing
                          financing to Parent."

         7.      If the merger of the Company into Parent (the "Merger")
                 contemplated by the Original Agreement, as hereby amended, has
                 not been consummated by February 1, 1996, then the $225,000
                 deposit held pursuant to the Escrow Agreement shall be
                 disbursed to Sellers by Bethea, Jordan & Griffin, P.A.
                 ("Escrow Agent"), PROVIDED, HOWEVER, that (i) such $225,000
                 shall be credited as a partial payment of the Consideration if
                 the Merger is later consummated and (ii) if either of (a) the
                 Closing of the Merger or (b) the closing of Parent's pending
                 financing arrangements with ING are not closed on or prior to
                 February 29, 1996 due to a breach by the Company or Sellers of
                 the Original Agreement, as hereby amended, then the Escrow
                 Agent shall not disburse any funds to Sellers and, if




                                      2
<PAGE>   96
                 previously disbursed, Sellers shall promptly (and in any event
                 within two Business Days after Parent's written request) repay
                 to Parent the entire $225,000 previously disbursed from the
                 Escrow.

         8.      The Original Agreement and the Escrow Agreement are hereby
                 amended to provide that (a) the total amount to be held by the
                 Escrow Agent pursuant to the Escrow Agreement after Closing
                 shall be $187,500, (b) the cash portion of such $187,500 shall
                 be held by the Escrow Agent in an interest bearing account
                 with interest accruing to the Sellers, (c) the claim period
                 provided for in the Escrow Agreement shall be shortened to
                 provide that the Escrow Agent shall hold the $187,500, and
                 that claims can be made, only for a period of six (6) months,
                 and (d) the amounts to be released to Sellers' Representative
                 in the first six months of the Escrow shall be reduced by
                 one-half.

         9.      The parties agree to execute a formal Amendment to the Escrow
                 Agreement prior to Closing incorporating the changes and
                 modifications set forth in paragraph 8 of this Amendment No.
                 1.

         10.     Except as herein amended, all terms, provisions and conditions
                 of the Original Agreement, all Exhibits and Schedules thereto
                 and all documents executed in connection therewith shall
                 continue in full force and effect and shall remain enforceable
                 and binding in accordance with their terms.

         11.     This Amendment No. 1 may be executed in any number of
                 identical counterparts, each of which shall for all purposes
                 be deemed an original and all of which constitute,
                 collectively, one agreement.

         12.     This Amendment No. 1 shall be governed by and construed in
                 accordance with the laws of the State of New York.

         13.     In the event of a conflict between the terms and conditions of
                 the Original Agreement and





                                       3

                 the terms and conditions of this Amendment No. 1, then the
                 terms and conditions of this Amendment No. 1 shall prevail.


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

("Company"), and the shareholders of the Company (collectively, the "Sellers").

                 Parent, the Company and Sellers entered into the Original

are hereby acknowledged, Parent and Sellers covenant and agree as follows:

         1.      Section 1.1 of the Original Agreement, as amended by Amendment
                 No. 1, is hereby deleted  and replaced with the following:

                          1.1  THE MERGER.  Upon the terms and subject to
                 conditions of this Agreement and in accordance with Chapter 17
                 of the Revised Code  of the State of Ohio (the "GCL") at the
                 Effective Time, the Company shall be merged with and into the
                 Parent (the "Merger") and the separate corporate existence of
                 the Company shall cease.  After the Merger, the Parent shall
                 continue as the surviving corporation (sometimes hereinaf-





                                      
<PAGE>   101
                 ter referred to as the "Surviving Corporation").  The Merger
                 shall have the effects as provided in the applicable
                 provisions of the GCL.  Without limiting the generality of the
                 foregoing, upon the Merger, all the rights, privileges,
                 immunities, powers and franchises of the Company and the
                 Parent shall vest in the Surviving Corporation and, except as
                 otherwise provided for in this Agreement, all obligations,
                 duties, debts and liabilities of the Company and the Parent
                 shall be the obligations, duties, debts and liabilities of the
                 Surviving Corporation.

         2.      Section 1.7(c) of the Original Agreement, as amended by
                 Amendment No. 1, is hereby deleted and replaced with the
                 following:

                                  (c)  On the Closing Date, the Parent and the
                 Company will cause an appropriate Certificate of Merger to be
                 executed and filed with the Secretary of State of South
                 Carolina in such form and executed as provided in the BCA.
                 The Parent and the Company will also cause an appropriate
                 Certificate of Merger to be executed and filed with the
                 Secretary of State of Ohio in such form and executed as
                 provided in the GCL.  The Merger shall become effective on the
                 date on which both the South Carolina and Ohio Certificates of
                 Merger have been duly filed with the Secretaries of State or
                 such time as is agreed upon by the parties and specified in
                 the Ohio Certificate of Merger, and such time is hereinafter
                 referred to as the "Effective Time".

         3.      Except as herein amended, all terms, provisions and conditions
                 of the Original Agreement, as amended by Amendment No. 1, all
                 Exhibits and Schedules thereto and all documents executed in
                 connection therewith shall continue in full force and effect
                 and shall remain enforceable and binding in accordance with
                 their terms.

         4.      This Amendment No. 2 may be executed in any number of
                 identical counterparts, each of which shall for all purposes
                 be deemed an original

                 and all of which constitute, collectively, one agreement.

         5.      This Amendment No. 2 shall be governed by and construed in
                 accordance with the laws of the State of New York.

         6.      In the event of a conflict between the terms and conditions of
                 the Original Agreement and             the terms and
                 conditions of this Amendment No. 2, then the terms and
                 conditions of this Amendment No. 2 shall prevail.

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

                                       TO
                      THE AGREEMENT AND PLAN OF MERGER

                         PHONETEL TECHNOLOGIES, INC.
                         INTERNATIONAL PAY PHONES, INC.
                                [South Carolina]
                                      AND
               THE SHAREHOLDERS OF INTERNATIONAL PAY PHONES, INC.


                 Amendment No. 1, dated as of January 16, 1996 ("Amendment No.
1"), to the Agreement and Plan of Merger, dated as of November 22, 1995 (the
"Original Agreement"), among PhoneTel Technologies, Inc., an Ohio corporation
("Parent"), International Pay Phones, Inc., a South Carolina corporation
("Company"), and the shareholders of the Company (collectively, the "Sellers").

                 Parent and Sellers entered into the Original Agreement on
November 22, 1995.  Parent and Sellers desire to amend the Original Agreement
to make the changes set forth below.

                 NOW THEREFORE, in consideration of the agreements herein set
forth and for other valuable consideration, the receipt and adequacy of which
are hereby acknowledged, Parent and Sellers covenant and agree as follows:

         1.      Alton L. Huffman is hereby added as a party to the Original
                 Agreement.  Exhibit A to the Original Agreement is hereby
                 deleted and Exhibit A attached to this Amendment No. 1 is
                 hereby substituted in its place.

         2.      The Closing as defined in Section 1.7(a) of the Original
                 Agreement shall take place on or before February 29, 1996, as
                 may be mutually agreed by Buyer and Sellers, and the term
                 "Closing Date", as defined and used in the Original Agreement,
                 shall be amended to mean the date on which the Closing
                 actually takes place.
<PAGE>   109
         3.      The term "Buyer" as used in the Original Agreement is hereby
                 deleted and replaced with the term "Parent" as defined and
                 used in the Original Agreement.

         4.      The term "Buyer" is hereby eliminated as a defined term from
                 Section 9.1 of the Original Agreement.

         5.      The following Section 1.4(c)(v) is added to the Original
                 Agreement:

                          "The Consideration shall be increased by an amount
                          equal to the Company's net operating loss, before
                          depreciation and amortization, from January 11, 1996
                          through the date of Closing as reflected on the
                          Company's income statement which shall be prepared on
                          the date of Closing in accordance with generally
                          accepted accounting practices."

         6.      Section 8.2(a) of the Original Agreement is hereby amended to
                 add the following language at the end of such Section:

                          ", and, from and after the Closing Date, Parent may
                          assign its rights hereunder to any party providing
                          financing to Parent."

         7.      If the merger of the Company into Parent (the "Merger")
                 contemplated by the Original Agreement, as hereby amended, has
                 not been consummated by February 1, 1996, then the $225,000
                 deposit held pursuant to the Escrow Agreement shall be
                 disbursed to Sellers by Bethea, Jordan & Griffin, P.A.
                 ("Escrow Agent"), PROVIDED, HOWEVER, that (i) such $225,000
                 shall be credited as a partial payment of the Consideration if
                 the Merger is later consummated and (ii) if either of (a) the
                 Closing of the Merger or (b) the closing of Parent's pending
                 financing arrangements with ING are not closed on or prior to
                 February 29, 1996 due to a breach by the Company or Sellers of
                 the Original Agreement, as hereby amended, then the Escrow
                 Agent shall not disburse any funds to Sellers and, if




                                      2
<PAGE>   110
                 previously disbursed, Sellers shall promptly (and in any event
                 within two Business Days after Parent's written request) repay
                 to Parent the entire $225,000 previously disbursed from the
                 Escrow.

         8.      The Original Agreement and the Escrow Agreement are hereby
                 amended to provide that (a) the total amount to be held by the
                 Escrow Agent pursuant to the Escrow Agreement after Closing
                 shall be $187,500, (b) the cash portion of such $187,500 shall
                 be held by the Escrow Agent in an interest bearing account
                 with interest accruing to the Sellers, (c) the claim period
                 provided for in the Escrow Agreement shall be shortened to
                 provide that the Escrow Agent shall hold the $187,500, and
                 that claims can be made, only for a period of six (6) months,
                 and (d) the amounts to be released to Sellers' Representative
                 in the first six months of the Escrow shall be reduced by
                 one-half.

         9.      The parties agree to execute a formal Amendment to the Escrow
                 Agreement prior to Closing incorporating the changes and
                 modifications set forth in paragraph 8 of this Amendment No.
                 1.

         10.     Except as herein amended, all terms, provisions and conditions
                 of the Original Agreement, all Exhibits and Schedules thereto
                 and all documents executed in connection therewith shall
                 continue in full force and effect and shall remain enforceable
                 and binding in accordance with their terms.

         11.     This Amendment No. 1 may be executed in any number of
                 identical counterparts, each of which shall for all purposes
                 be deemed an original and all of which constitute,
                 collectively, one agreement.

         12.     This Amendment No. 1 shall be governed by and construed in
                 accordance with the laws of the State of New York.

         13.     In the event of a conflict between the terms and conditions of
                 the Original Agreement and

Agreement, effective as of the date and year first above written.

                        THE AGREEMENT AND PLAN OF MERGER
                                     AMONG

                                      AND
               THE SHAREHOLDERS OF INTERNATIONAL PAY PHONES, INC.


                 Amendment No. 2, dated as of February 23, 1996 ("Amendment No.

("Company"), and the shareholders of the Company (collectively, the "Sellers").

                 Parent, the Company and Sellers entered into the Original
Agreement on November 22, 1995.  The Original Agreement was amended pursuant to
Amendment No. 1, dated as of January 16, 1996, among Parent, the Company and

                 NOW THEREFORE, in consideration of the agreements herein set
forth and for other valuable consideration, the receipt and adequacy of which
are hereby acknowledged, Parent and Sellers covenant and agree as follows:

         1.      Section 1.1 of the Original Agreement, as amended by Amendment
                 No. 1, is hereby deleted  and replaced with the following:

                          1.1  THE MERGER.  Upon the terms and subject to
                 conditions of this Agreement and in accordance with Chapter 17
                 of the Revised Code  of the State of Ohio (the "GCL") at the
                 Effective Time, the Company shall be merged with and into the
                 Parent (the "Merger") and the separate corporate existence of
                 the Company shall cease.  After the Merger, the Parent shall
                 continue as the surviving corporation (sometimes hereinaf-





                                      
<PAGE>   115
                 ter referred to as the "Surviving Corporation").  The Merger
                 shall have the effects as provided in the applicable
                 provisions of the GCL.  Without limiting the generality of the
                 foregoing, upon the Merger, all the rights, privileges,
                 immunities, powers and franchises of the Company and the
                 Parent shall vest in the Surviving Corporation and, except as
                 otherwise provided for in this Agreement, all obligations,
                 duties, debts and liabilities of the Company and the Parent
                 shall be the obligations, duties, debts and liabilities of the
                 Surviving Corporation.

         2.      Section 1.7(c) of the Original Agreement, as amended by
                 Amendment No. 1, is hereby deleted and replaced with the
                 following:

                                  (c)  On the Closing Date, the Parent and the
                 Company will cause an appropriate Certificate of Merger to be
                 executed and filed with the Secretary of State of South
                 Carolina in such form and executed as provided in the BCA.
                 The Parent and the Company will also cause an appropriate
                 Certificate of Merger to be executed and filed with the
                 Secretary of State of Ohio in such form and executed as
                 provided in the GCL.  The Merger shall become effective on the
                 date on which both the South Carolina and Ohio Certificates of
                 Merger have been duly filed with the Secretaries of State or
                 such time as is agreed upon by the parties and specified in
                 the Ohio Certificate of Merger, and such time is hereinafter
                 referred to as the "Effective Time".

         3.      Except as herein amended, all terms, provisions and conditions
                 of the Original Agreement, as amended by Amendment No. 1, all
                 Exhibits and Schedules thereto and all documents executed in
                 connection therewith shall continue in full force and effect
                 and shall remain enforceable and binding in accordance with
                 their terms.

         4.      This Amendment No. 2 may be executed in any number of
                 identical counterparts, each of which shall for all purposes
                 be deemed an original

                 and all of which constitute, collectively, one agreement.

         5.      This Amendment No. 2 shall be governed by and construed in
                 accordance with the laws of the State of New York.

         6.      In the event of a conflict between the terms and conditions of
                 the Original Agreement and             the terms and
                 conditions of this Amendment No. 2, then the terms and
                 conditions of this Amendment No. 2 shall prevail.

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

Directors of the Parent and the Company have each approved this Agreement and

<PAGE>   3
terms of this Agreement and the Business Corporation Act of the State of
Tennessee (the "BCA"); and
                 WHEREAS, for United States federal income tax purposes, it is
intended that the Merger (as defined herein) shall qualify as a reorganization
under Section 368(a) of the Internal Revenue Code of 1986, as amended (the
"Code"), and this Agreement is intended to be and is adopted as a plan of
reorganization within the meaning of Section 368 of the Code;
                 NOW, THEREFORE, in consideration of the mutual agreements,
covenants, representations and warranties set forth herein, and intending to be

                                 THE MERGER
                                 ----------
                 1.1      THE MERGER.  Upon the terms and subject to conditions
of this Agreement and in accordance with the BCA at the Effective Time, the
Company shall be merged with and into the Buyer (the "Merger") and the separate

effects as provided in the applicable provisions of the BCA.  Without limiting
the generality of the foregoing, upon the Merger, all the rights, privileges,
immunities, powers and franchises of the Company and the Buyer shall vest in
the Surviving Corporation and, except as otherwise provided for in this
Agreement, all obligations, duties, debts and liabilities of the Company and
the Buyer shall be the obligations, duties, debts and liabilities of the

                 1.2      CONVERSION OF SHARES.  At the Effective Time:
                          (a)  Each share of common stock, par value $1.00 per
share, of the Company ("Company Shares") outstanding immediately prior to the
Effective Time shall be converted into the right to receive a percentage of the
Consideration equal to the percentage such Company Share represents of all
Company Shares.  The consideration (the "Consideration") shall equal the sum of
(i) the excess of (A) the product of $3800 and the Company Phones Amount, over
(B) $15,000, subject to adjustment as set forth in Section 1.4 hereof (to be
paid one half in cash and one half in certificates representing Parent Shares,
valued at the Stock Price) plus (ii) the sum of (A) the product of $1,000 and
the





                                       3
<PAGE>   5
Customer Phones Amount plus (B) $25,000 (to be paid in Parent Shares, valued at
the Stock Price).
                          (b)  Each share of common stock of Buyer outstanding
immediately prior to the Effective Time shall be converted into one share of
common stock of the Surviving Corporation and shall constitute the only
outstanding shares of capital stock of the Surviving Corporation.
                 1.3      CLOSING PAYMENT.  (a)  Not later than three business
days prior to the Closing, Seller's Representative shall deliver to Buyer a
good faith estimate of the adjustments to the Consideration as of the Closing
Date, including all the detail required by Section 1.4 hereof.
                          (b)  At the Closing, Parent shall pay to Seller
Representative (for distribution Pro Rata to Sellers) an amount equal to the
Consideration which would be payable if adjusted pursuant to Section 1.4 (using
the good faith estimates delivered pursuant to paragraph (a) above); provided
that such amount shall be reduced by $125,000 (one-half in cash and one-half in
Parent Shares, valued at the Stock Price).
                 1.4      Consideration Adjustments.
                          -------------------------

<PAGE>   6
                          (a)  COMPANY PHONE AMOUNT.  The Consideration shall
be adjusted to reflect the actual Company Phones Amount and the Customer Phones
Amount, as provided in Section 1.2(a).  In addition, the Consideration shall be
further adjusted by the following calculations, provided that the adjustments
in Paragraph (b) shall be made before any adjustments are made pursuant to
paragraph (c).

                                  (i)  If at the Closing Date the Average Term
         is less than 30 months, then the Consideration shall be reduced by
         multiplying (A) the amount calculated pursuant to Section 1.2(a)(i),
         (as adjusted by Section 1.4(a)), by (B) a fraction, the numerator of
         which will be the Average Term and the denominator of which will be
         30.
                                  (ii)  If the Average Income is less than $115
         per phone then the Consideration shall be reduced by multiplying (A)
         the amount calculated pursuant to Section 1.2(a)(i) (as adjusted by
         Section 1.4(a) and 1.4(b)(i)) by (B) a fraction, the numerator of
         which will be





                                       5
<PAGE>   7
         the Average Income and the denominator of which will be 115.
                          (c)  Other Adjustments.
                               -----------------
                                  (i)  The Consideration shall be decreased by
         an amount equal to the excess of (A) all Liabilities of the Company as
         of the Closing over (B) the sum of all Current Assets.  For purposes
         of this paragraph 1.4(c)(i), all amounts specified in clauses (ii) and
         (iii) below or in respect of telephone bills due on or after the
         Closing Date shall be disregarded.
                                  (ii)  The Consideration shall be decreased by
         the amount owing in respect of any telephone bills received by the
         Company on or before the Closing Date which are due prior to the
         Closing Date but not paid by the Company or Sellers on or before the
         Closing Date.
                                  (iii)  The Consideration shall be increased
         by the excess of (A) the amount accrued as of the Closing Date as
         receivables from AT&T, Opticon, and third and fourth quarter APCC (but
         only to the extent such amount is received by the Company within 150
         days after the Closing Date) over (B) the amount of all site
         commissions accrued but not





                                       6
<PAGE>   8
         paid as of the Closing Date.  In the event the amount specified in
         clause (B) above exceeds the amount in clause (A) above, the
         Consideration shall be decreased by the amount of such excess.
                                  (iv)  The consideration shall be decreased by
         the amount of all indebtedness or other Liabilities relating to the
         vehicles specified in Schedule 5.18(d) to the Disclosure Schedule.
                          (d)  The number of Parent Shares to be issued
hereunder shall be adjusted to account for any stock splits, reverse stock
splits, stock dividends, or any similar transaction with respect to Parent
Shares.
                          (e)  As soon as practicable after the Closing Date
(but in any event not more than 150 days after the Closing Date), the Parent
shall cause to be prepared and delivered to Seller Representative and the
Escrow Agent a schedule (the "Adjustment Schedule") which shows, as of the
Closing Date, the calculation of the Consideration as provided in Section
1.2(a) and as adjusted pursuant to this Section 1.4.
                                  (i)  Upon receipt of the Adjustment Schedule,
Seller Representative





                                       7
<PAGE>   9
         shall have the right during the succeeding 10-day period to examine
         the Adjustment Schedule and all records used to prepare such
         Adjustment Schedule.  Seller Representative shall notify Parent in
         writing, on or before the last day of the 10-day period, of any good
         faith objections to the Adjustment Schedule, setting forth a
         reasonably specific description of such objections and the dollar or
         other amount, as the case may be, of each objection.
                                  (ii)  If Seller Representative in good faith
         objects to the Adjustment Schedule, Seller Representative and Parent
         shall attempt to resolve any such objections within 10 days of
         Parent's receipt of such objections.  If Parent and Seller
         Representa-tive are unable to resolve the matter within such 10-day
         period, they shall jointly appoint a mutually acceptable firm of
         independent certified public accountants (or, if they cannot agree on
         a mutually acceptable firm, they shall cause their respective
         accounting firms to select such firm) within five days after the end
         of such 10-day period.  The fees





                                       8
<PAGE>   10
         of such independent certified public accountants shall be divided
         equally between Parent and the Seller Representative (on behalf of all
         Sellers).  Such firm's resolution of the dispute shall be conclusive
         and binding upon the Sellers and Parent.
                                  (iii)  The Adjustment Schedule shall be
         deemed complete upon the earlier of (A) the eleventh (11th) day after
         Parent's delivery of the Adjustment Schedule to Seller Representative,
         unless prior to such day Seller Representative shall have notified
         Parent of a dispute in accordance with paragraph (i), and (B) the
         resolution of all disputes, pursuant to paragraph (ii).  Within two
         business days following completion of the Adjustment Schedule as
         aforesaid, either
                 (A)      Parent shall pay Seller Representative, on behalf of
                 Sellers, the amount, if any, by which the Consideration (as
                 adjusted) exceeds the amount paid pursuant to Section 1.3(b);
                 or
                 (B)      Seller Representative, on behalf of Sellers, shall
                 pay to Buyer the amount, if any, by





                                       9
<PAGE>   11
         which the amount paid pursuant to Section 1.3(b) exceeds the
         Consideration (as adjusted).
         (C)      All payments pursuant to this Section 1.4(e)(iii)
         shall be 50% cash and 50% Parent Shares (valued at the Stock Price)
                 1.5      Escrow.
                          ------
                          (a)  Simultaneously herewith, Parent, the Company,
Seller Representative (on behalf of the Sellers) and Bethea, Jordan & Griffin,
P.A., as escrow agent (the "Escrow Agent") are entering into an Escrow
Agreement in the form attached hereto as Exhibit B, and Parent is depositing
$75,000 (the "Escrow Amount") with the escrow agent, to be held and disposed of
by the Escrow Agent pursuant to the Escrow Agreement.  In the event the Closing
does not occur due to (i) a material breach of this Agreement by Parent or (ii)
the failure of the condition set forth in Section 6.1(f) hereof (which failure
has not been waived by Parent), Seller Representative (on behalf of all
Sellers, Pro Rata) shall be entitled to receive the entire Escrow Amount, as
liquidated damages, and shall have no other rights or remedies in respect of
this Agreement.  Within three business days after such receipt, the Seller
Representative may sell to Parent for cash, at $1.05 per Parent Share, all of
the Parent Shares theretofore constituting a part of the Escrow Amount.

                          (b)  At the Closing, Parent shall deposit an
additional $50,000 with the Escrow Agent, which shall become part of the Escrow
Amount, and the Jail Escrow Amount.
                          (c)  Delivery of funds and Parent Shares by the
Escrow Agent to the applicable parties shall be pursuant to the terms of the
Escrow Agreement.
                          (d)  All sums deposited by Parent with the Escrow
Agent shall be 50% cash and 50% Parent Shares (valued at the Stock Price),
except the Jail Escrow Amount.
                 1.6      APPOINTMENT OF THE SELLER REPRESENTATIVE.  Each
Seller hereby irrevocably appoints Nickey Maxey (the "Seller Representative")
as such Seller's attorney-in-fact and representative, to do any and all things

<PAGE>   13

                 1.7      The Closing.

such Seller are necessary to authorize such execution, delivery and
consummation.  No power of attorney has been granted by such Seller with

                 2.3      CONSENTS AND APPROVALS; NO VIOLATION.   Except as set
forth on Schedule 2.3 of the Disclosure Schedule, neither the execution and
delivery of this Agreement and the Other Documents, nor the consummation of the

                          (k)  take, or agree in writing or otherwise to take,
any of the foregoing actions or any action which would make any representation
or warranty of the Company or Sellers contained in this Agreement untrue or
incorrect as of the date when made or as of any future date or which could

                                  7.1              SURVIVAL OF REPRESENTATIONS
AND WARRANTIES.  All representations and warranties of the Sellers and the

"Buyer Indemnified Party"), from and against any and all Losses asserted
against, resulting to, imposed upon or





                                       63
<PAGE>   65
incurred by any Buyer Indemnified Party, directly or indirectly, by reason of
or resulting from:
                            (i)    the breach of or any inaccuracy in any
              of the representations and warranties of the Sellers or the
              Company contained in or made pursuant to any section of this
              Agreement, or any facts or circumstances constituting such        
              breach or inaccuracy;

                            (ii)    the breach or nonperformance of
              any covenant or agreement of the Sellers or the Company contained
              in or made pursuant to this Agreement or any facts or
              circumstances constituting such breach or nonperformance; and

                            (iii)    any and all Taxes imposed upon
              the Company or Sellers with respect to any taxable period (or any
              portion thereof) ending on or before the Closing Date.  Without
              limiting the generality of the foregoing, Sellers shall
              indemnify, defend and hold harmless any Buyer Indemnified Party
              from and against any and all Losses asserted against, resulting
              to, imposed upon or incurred by any Buyer Indemnified
              Party, directly or





                                       64
<PAGE>   66
         indirectly, by reason or resulting from any and all Taxes imposed upon
         the Company or the Sellers arising directly or indirectly from (i) the
         failure of the Company to be an S corporation or the termination of
         the Company's status as an S corporation and (ii) the imposition of
         any Taxes on the Company for any taxable period in which the Company's
         election of subchapter S status was in effect (including but not
         limited to those Taxes described in Section 1374 and 1375 of the
         Code).
                                  7.4              INDEMNIFICATION BY THE

Party, directly or indirectly, by reason of or resulting from:
                            (i)    the breach of or any inaccuracy in any
              of the representations and warranties of the Parent contained     
              in or made pur-

                                      65
<PAGE>   67
              suant to this Agreement or any facts or circumstances 
              constituting such breach or inaccuracy; and

                            (ii)    the breach or non-performance
              of any agreement of the Parent contained in or made pursuant to
              this Agreement or any facts or circumstances constituting such    
              breach or nonperformance.

                                  7.5        Indemnification Procedures.
                                             --------------------------
                                             (a)    NOTICE.  If any legal
proceeding shall be threatened or instituted or any claim or demand shall be
asserted by any Buyer Indemnified Party or Seller Indemnified Party in respect
of which indemnification may be sought under the provisions of this Agreement,
the party seeking indemnification (the "Claiming Party") shall promptly cause
written notice of the assertion of any such claim, demand or proceeding of
which it has knowledge to be forwarded to the party from whom it is claiming
indemnification (the "Indemnitor").  Such notice shall contain a reference to
the provisions hereof or of such other agreement, instrument or certificate
delivered pursuant hereto, in respect of which such claim is being made, and
shall specify, in reasonable detail, the amount of such Loss if





                                       66
<PAGE>   68
determinable at such time.  The Claiming Party's failure to give the Indemnitor
prompt notice shall not preclude the Claiming Party from seeking
indemnification from the Indemnitor unless the Claiming Party's failure has
materially prejudiced the Indemnitor's ability to defend the claim, demand or
proceeding.
                                        (b)    THIRD PARTY CLAIMS.  If the
Claiming Party seeks indemnification from the Indemnitor as a result of a claim
or demand being made by a third party (a "Third Party Claim"), the Indemnitor
shall have the right to promptly assume the control of the defense of such
Third Party Claim, including, at its own expense, employment by it of counsel
reasonably satisfactory to the Claiming Party. The Claiming Party may, in its
sole discretion and at its own expense, employ counsel to represent it in the
defense of the Third Party Claim, and in such event counsel for the Indemnitor
shall cooperate with counsel for the Claiming Party in such defense, provided
that the Indemnitor shall direct and control the defense of such Third Party
Claim or proceeding.  Except with the written consent of the Claiming Party,
the Indemnitor shall not consent to the entry of any judgment nor enter into
any settlement of such Third Party Claim which (i) does not include as an
unconditional term





                                       67
<PAGE>   69
thereof the release of the Claiming Party from all liability in respect of such
Third Party Claim and (ii) results in the imposition on the Claiming Party of
any remedy other than money damages; provided, however, that the Claiming Party
shall not unreasonably withhold or delay its consent to the entry of any
judgment or any settlement of a Third Party Claim.  If the Indemnitor elects
not to exercise its rights to assume the defense of the Third Party Claim, or
if injunctive relief is sought which would have an adverse effect on the
Claiming Party, the Claiming Party may, but shall have no obligation to, defend
against such Third Party Claim or legal proceeding in such manner as it may
deem appropriate, and the Claiming Party may compromise or settle such Third
Party Claim and proceeding without the Indemnitor's consent so long as the
Claiming Party acts in a commercially reasonable manner (without regard to the
Claiming Party's indemnification rights hereunder).
                                        (c)    PAYMENT.  After any final
judgment or award shall have been rendered by a court, arbitration board or
administrative agency of competent jurisdiction and the time in which to appeal
therefrom shall have expired, or a settlement shall have been consummated, or
the Claiming Party and the Indemnitor shall arrive at a





                                       68
<PAGE>   70
mutually binding agreement with respect to each separate matter alleged to be
indemnified by the Indemnitor hereunder, the Claiming Party shall forward to
the Indemnitor notice of any sums due and owing by it with respect to such
matter (in accordance with Section 8.10 hereof) and the Indemnitor shall pay
all of the sums so owing to the Claiming Party within 10 days after the date of
such notice.  Notwithstanding the foregoing, the obligation of Sellers to
indemnify under this Article VII shall be limited to 50% of the aggregate
Consideration; such indemnification obligation shall be satisfied 50% in cash
(by wire transfer, certified or bank cashier's check) and 50% in Parent Shares
(valued at the Stock Price).
                                        (d)    ESCROW.  To the extent that the
Escrow Amount has not been released pursuant to the Escrow Agreement, the Buyer
Indemnified Party's right to  indemnification and to be held harmless pursuant

                                       TO
                        THE AGREEMENT AND PLAN OF MERGER

                          PHONETEL TECHNOLOGIES, INC.
                         INTERNATIONAL PAY PHONES, INC.
                                  [Tennessee]
                                      AND
               THE SHAREHOLDERS OF INTERNATIONAL PAY PHONES, INC.


                 Amendment No. 1, dated as of January 16, 1996 ("Amendment No.
1"), to the Agreement and Plan of Merger, dated as of November 22, 1995 (the
"Original Agreement"), among PhoneTel Technologies, Inc., an Ohio corporation
("Parent"), International Pay Phones, Inc., a Tennessee corporation
("Company"), and the shareholders of the Company (collectively, the "Sellers").

                 Parent and Sellers entered into the Original Agreement on
November 22, 1995.  Parent and Sellers desire to amend the Original Agreement
to make the changes set forth below.

                 NOW THEREFORE, in consideration of the agreements herein set
forth and for other valuable consideration, the receipt and adequacy of which
are hereby acknowledged, Parent and Sellers covenant and agree as follows:

         1.      The Closing as defined in Section 1.7(a) of the Original
                 Agreement shall take place on or before February 29, 1996, as
                 may be mutually agreed by Parent and Sellers, and the term
                 "Closing Date", as defined and used in the Original Agreement,
                 shall be amended to mean the date on which the Closing
                 actually takes place.

         2.      The term "Buyer" as used in the Original Agreement is hereby
                 deleted and replaced with the term "Parent" as defined and
                 used in the Original Agreement.
<PAGE>   96
         3.      The term "Buyer" is hereby eliminated as a de
                 fined term from Section 9.1 of the Original Agreement.

         4.      The following Section 1.4(c)(v) is added to the
                 Original Agreement:

                          "The Consideration shall be increased by an amount
                          equal to the Company's net operating loss, before
                          depreciation and amortization, from January 11, 1996
                          through the date of Closing as reflected on the
                          Company's income statement which shall be prepared on
                          the date of Closing in accordance with generally
                          accepted accounting practices."

         5.      Section 8.2(a) of the Original Agreement is hereby amended to
                 add the following language at the end of such Section:

                          ", and, from and after the Closing Date, Parent may
                          assign its rights hereunder to any party providing
                          financing to Parent."

         6.      If the merger of the Company into Parent (the "Merger")
                 contemplated by the Original Agreement, as hereby amended, has
                 not been consummated by February 1, 1996, then the $75,000
                 deposit held pursuant to the Escrow Agreement shall be
                 disbursed to Sellers by Bethea, Jordan & Griffin, P.A.
                 ("Escrow Agent"), PROVIDED, HOWEVER, that (i) such $75,000
                 shall be credited as a partial payment of the Consideration if
                 the Merger is later consummated and (ii) if either of (a) the
                 Closing of the Merger or (b) the closing of Parent's pending
                 financing arrangements with ING are not closed on or prior to
                 February 29, 1996 due to a breach by the Company or Sellers of
                 the Original Agreement, as hereby amended, then the Escrow
                 Agent shall not disburse any funds to Sellers and, if
                 previously disbursed, Sellers shall promptly (and in any event
                 within two Business Days after Parent's written request) repay
                 to Parent the entire $75,000 previously disbursed from the
                 Escrow.

         7.      The Original Agreement and the Escrow Agreement are hereby
                 amended to provide that (a) the total amount (exclusive of the
                 Jail Escrow Amount) to be held by the Escrow Agent pursuant to
                 the Escrow Agreement after Closing shall be $62,500, (b) the
                 cash portion of the $62,500 shall be held by the Escrow Agent
                 in an interest bearing account with interest accruing to the
                 Sellers, (c) the claim period provided for in the Escrow
                 Agreement shall be shortened to provide that the Escrow Agent

and the shareholders of the Company (collectively, the "Sellers").

            Parent, the Company and Sellers entered into the Original Agreement
on November 22, 1995.  The Original Agreement was amended pursuant to Amendment
No. 1, dated as of January 16, 1996 among Parent, the Company and Sellers
("Amendment No. 1").  Parent, the Company and Sellers desire to further amend

            NOW THEREFORE, in consideration of the agreements herein set forth
and for other valuable consideration, the receipt and adequacy of which are
hereby acknowledged, Parent and Sellers covenant and agree as follows:
     
     1.     Section 1.1 of the Original Agreement, as amended by Amendment No.
            1, is hereby deleted and replaced with the following:

                         1.1  THE MERGER.  Upon the terms and subject to 
            conditions of this Agreement and in accordance with Chapter 17 of
            the Revised Code  of the State of Ohio (the "GCL") at the Effective

            "Merger") and the separate corporate existence of the Company shall
            cease.  After the Merger, the Parent shall continue as the
            surviving corporation (sometimes hereinaf-
            
<PAGE>   100
            ter referred to as the "Surviving Corporation").  The Merger shall 
            have the effects as provided in the applicable provisions of the 
            GCL.  Without limiting the generality of the foregoing, upon the 
            Merger, all the rights, privileges, immunities, powers and 
            franchises of the Company and the Parent shall vest in the
            Surviving Corporation and, except as otherwise provided for in 
            this Agreement, all obligations, duties, debts and liabilities 
            of the Company and the Parent shall be the obligations, duties, 
            debts and liabilities of the Surviving Corporation.

     2.     Section 1.7(c) of the Original Agreement, as amended by Amendment
            No. 1, is hereby deleted and replaced with the following:

                        (c)  On the Closing Date, the Parent and the Company 
            will cause appropriate Articles of Merger (the "Articles of
            Merger") to be executed and filed with the Secretary of State of
            Tennessee in such form and executed as provided in the BCA.  The
            Parent and the Company will also cause an appropriate Certifi- cate
            of Merger (the "Certificate of Merger") to be executed and filed
            with the Secretary of State of Ohio in such form and executed as
            provided in the GCL.  The Merger shall become effective on the date
            on which the Articles of Merger and the Certificate of Merger has
            been duly filed with the appropriate Secretary of State or such
            time as is agreed upon by the parties and specified in the
            Certificate of Merger, and such time is hereinafter referred to as
            the "Effective Time".

     3.     Except as herein amended, all terms, provisions and conditions of
            the Original Agreement, as amended by Amendment No. 1, all exhibits
            and Schedule thereto and all documents executed in connection
            therewith shall continue in full force and effect and shall remain
            enforceable and binding in accordance with their terms.

                          (c)  Each of the Sellers shall be entitled to receive
such percentage of the payment made pursuant to subsection (a)(i) and (ii) of
this Section 1, and shall have such percentage interest in the payment to the
Escrow Agent made pursuant to subsection (a)(iii) of this Section 1 as is set
forth opposite such Seller's name on Exhibit A hereto.
                 1.3      CLOSING PRICE ADJUSTMENT. (a)  If the number of PCS
Phones as of the Closing Date is greater than the PCS Phones Amount, the
Consideration shall be increased by the product obtained by multiplying an
amount to be mutually agreed upon by Buyer and the Sellers' Representative
(which shall be between $2500 and $4000), by the excess of (i) the number of
PCS Phones as of the Closing Date over (ii) the PCS Phones Amount.  For
purposes of this Section 1.3(a), PCS Phones added after November 16, 1995 shall
be counted only to the extent approved by Buyer.  If the amount to be paid for
the additional phones is disputed, then $2,500 would be paid at Closing, and if
the net to operator shows an average of $120 per month after ninety days, then
an additional $1,500 would be paid.
                          (b)  If the number of PCS Phones as of the Closing 
Date is less than the PCS Phones Amount, the





                                       4
<PAGE>   9
Consideration shall be decreased by the product obtained from multiplying
$4,000 by the excess of (i) the PCS Phones Amount over (ii) the number of PCS
Phones as of the Closing Date.
                          (c)  The Consideration shall be reduced by the
amount, if any, by which (x) the aggregate liabilities of PCS as of the Closing
Date exceeds (y) the current assets of PCS as of the Closing Date (excluding
any amounts payable pursuant to Section 5.11 hereof).
                          (d)  The Consideration shall be reduced by the amount
of all severance pay for the termination of any employees of PCS terminated by
PCS within one business day after the Closing, consistent with past practice of
PCS.  Buyer shall notify Seller's Representative of the employees to be
terminated within two days prior to the Closing.
                          (e)  As soon as practicable after the Closing Date,
the Buyer shall cause to be prepared and delivered to Sellers' Representative
and the Escrow Agent a schedule (the "Adjustment Schedule") which shows, as of
the Closing Date, each of the following items: (i) the current assets of PCS as
of the Closing Date, (ii) all liabilities of PCS as of the Closing Date, (iii)
the number of PCS Phones as of the Closing Date and (iv) the





                                       5
<PAGE>   10

                          (f)  Upon receipt of the Adjustment Schedule,
Sellers' Representative shall have the right during the succeeding 10 business
day period to examine the Adjustment Schedule and all records used to prepare
such Adjustment Schedule.  Sellers' Representative shall notify the Buyer and
the Escrow Agent in writing, on or before the last day of the 10 business day
period, of any good faith objections to the Adjustment Schedule, setting forth
a reasonably specific description of such objections and the dollar or other
amount, as the case may be, of each objection.
                          (g)  If Sellers' Representative in good faith objects
to the Adjustment Schedule, Sellers' Representative and the Buyer shall attempt
to resolve any such objections within 10 days of the Buyer's receipt of such
objections.  Upon such resolution, Buyer and Sellers' Representative shall
notify the Escrow Agent and furnish instructions for the delivery of funds from
the Escrow Account, and consistent with this Section 1.3.  If the Buyer and
Sellers' Representative are unable to resolve the matter within such 10
business day period, they shall jointly appoint a mutually acceptable firm of
independent





                                       6
<PAGE>   11
certified public accountants (or, if they cannot agree on a mutually acceptable
firm, they shall cause their respective accounting firms to select such firm)
within five days after the end of such 10 business day period, and shall notify
the Escrow Agent of the identity of such firm.  The fees of such independent
certified public accountants shall be divided equally between the Buyer and the
Sellers.  Such firm's resolution of the dispute shall be conclusive and binding
upon the Sellers and the Buyer.
                          (h)  The Adjustment Schedule shall be deemed complete
upon the earlier of (i) the eleventh (11th) day after the Buyer's delivery of
the Adjustment Schedule to Sellers' Representative, unless prior to such day
Sellers' Representative shall have notified the Buyer of a dispute in
accordance with paragraph (f), and (ii) the resolution of all disputes,
pursuant to paragraph (g).  Within two business days following completion of
the Adjustment Schedule as aforesaid, either
                                  (A)  Buyer shall pay Sellers, Pro Rata, the
         amount, if any, by which the Consideration (as adjusted) exceeds the
         amount paid at the Closing pursuant to Section 1.2(a); or

                                  (B)  Sellers shall pay to Buyer the amount,
         if any, by which the amount paid at the Closing pursuant to Section
         1.2(a) exceeds the Consideration (as adjusted).
                 1.4      DELIVERY OF ESCROW AMOUNT. Delivery of the Escrow
Amount by the Escrow Agent to the applicable parties shall be made pursuant to
the terms of the Escrow Agreement.

limitation, such Seller's Common Shares)) under, any of the terms, conditions
or provisions of any note, bond, mortgage, indenture, Encumbrance, Contract,
Permit, Order, or other instrument or obligation to which such Seller is a

3.11 of the Disclosure Schedule.
                 3.12     CONTRACTS. Schedule 3.12 of the Disclosure Schedule

available for inspection by the Buyer.  All written Contracts and all oral
Material Contracts (i) are valid and binding obligations of PCS and the other
parties thereto, (ii) are in full force and effect and are enforceable as to
PCS and the other parties thereto, in accordance with their respective terms,
and (iii) have not been amended or terminated except in the ordinary course of

thereunder, (ii) has given notice, to the knowledge of any Seller, that it
intends to terminate such Contract or (iii) has altered, in any way adverse to
PCS, its performance under such Contract.  No event or condition has occurred
(or is alleged by any other party to a Contract to have occurred) which, with
or without due notice or lapse of time or both, would constitute a breach or
event of default on the part of PCS, would provide a basis for a valid claim or
acceleration under any Contract as against PCS or would prevent PCS from





                                       28
<PAGE>   33
exercising and obtaining the full benefits of any rights or options contained
therein.  The telephone location contracts of PCS have an average remaining
life per PCS Phone of forty-two (42) months.  All PCS Phones are installed
pursuant to written location Contracts, except for not more than 150 PCS
Phones; to Sellers' knowledge such PCS Phones not subject to written Contracts
have been in place since 1993, and are not under any threat of removal or
termination.

are now being conducted in all material respects in compliance with all Laws
and Orders of all Governmental Authorities having jurisdiction over PCS and all
Permits relating to any of its properties or applicable to its business.
                          (b)   Except as and to the extent set forth on

full force and effect, and PCS has fulfilled its obligations under each of the
Permits, and no event has





                                       29
<PAGE>   34
occurred or condition or state of facts exists which constitutes or, after
notice or lapse of time or both, would constitute a default or violation under
any of the Permits or would permit revocation or termination of any of the
Permits.  No proceeding which might involve the revocation or termination of
any such Permits is pending or, to the knowledge of PCS or the Sellers,
threatened.
                          (c)     PCS has made all filings and received all
approvals in connection with the Permits which are necessary for the Buyer to
own and operate the property and assets of PCS and to conduct PCS's business as
it is currently and has heretofore been conducted.
                 3.14    LITIGATION AND ARBITRATION. (a)  Since January 1, 1992,

Order has been initiated, brought or commenced, or been pending or threatened,
against PCS or affecting its business, operations or assets (including actions
by or before any administrative body, arbitration or mediation panel or
Governmental Authority), except as set forth on Schedule 3.14(a) of the
Disclosure Schedule.  No Order of any Governmental Authority, arbitrator or
mediator is outstanding against PCS, its business, operations or assets.
Neither PCS nor any of the Sellers has knowledge





                                       30

                          (b)     No claim, action, suit, proceeding, inquiry

applicable laws and regulations.  PCS has taken no actions which might
reasonably be expected to result in any violations of ERISA or the Code.  The
consummation of the transactions contemplated by this Agreement will not

to severance pay, unemployment compensation or any other payment, except as
expressly provided herein.  There are no pending, threatened or anticipated
claims by or on behalf of any employee of PCS.

had in effect since its incorporation a valid election to be treated as an "S"
corporation for federal income tax purposes under the Code and in the State of
Florida, and none of PCS or the Sellers has taken or caused or permitted to be
taken any action during such periods that would have caused or permitted to be
taken any action during such periods that would have caused a termination of
such S election.
                          (b)  PCS has duly and timely filed all Tax Returns
required to be filed by it on or before the Closing Date or has received a

notice to Buyer, assume and control the defense of a Tax Claim involving only
Pre-Closing Taxes at their own cost and expense and with their own counsel.  If
the Sellers' Representative elects to assume the defense of any such Tax Claim,
notwithstanding anything to the contrary contained herein, (i) the Sellers'

Period and (iii) any Tax Claim that the Sellers' Representative has the ability
to control but does not timely elect to control pursuant to Section 7.7 (f),
such contest shall be controlled by the Buyer, and the Sellers agree to
cooperate with the Buyer and its affiliates in pursuing such contest.  In
connection with any such contest that relates to (ii) or (iii) above, the Buyer
shall keep the Sellers informed of all material developments and events
relating to such Tax claim and Sellers, at their own cost and expense, shall

                 7.8      INDEMNIFICATION PROCEDURES.
                          (a)  NOTICE.  If any legal proceeding shall be
threatened or instituted or any claim or demand shall be asserted by any Buyer
Indemnified Party or Seller Indemnified Party in respect of which
indemnification may be sought under the provisions of this Agreement, the party
seeking indemnification (the "Claiming Party") shall promptly cause written
notice of the assertion of any such claim, demand or proceeding of which it has
knowledge to be forwarded to the party from whom it is claiming indemnification
(the "Indemnitor").  Such notice shall contain a reference to the provisions
hereof or of such other agreement, instrument or certificate delivered pursuant
hereto, in respect of which such claim is being made, and shall specify, in
reasonable detail, the amount of such Loss if determinable at such time.  The
Claiming Party's failure to give the Indemnitor prompt notice shall not
preclude the Claiming Party from seeking indemnification from the Indemnitor
unless the Claiming Party's failure has materially prejudiced the Indemnitor's
ability to defend the claim, demand or proceeding.
                          (b)  THIRD PARTY CLAIMS.  If the Claiming Party seeks
indemnification from the Indemnitor as a 





                                       64
<PAGE>   69

result of a claim or demand being made by a third party (a "Third Party Claim"),
the Indemnitor shall have the right to promptly assume the control of the
defense of such Third Party Claim, including, at its own expense, employment
by it of counsel reasonably satisfactory to the Claiming Party. The Claiming
Party may, in its sole discretion and at its own expense, employ counsel to
represent it in the defense of the Third Party Claim, and in such event counsel
for the Indemnitor shall cooperate with counsel for the Claiming Party in such
defense, provided that the Indemnitor shall direct and control the defense of
such Third Party Claim or proceeding.  Except with the written consent of the
Claiming Party, the Indemnitor shall not consent to the entry of any judgment
nor enter into any settlement of such Third Party Claim which (i) does not
include as an unconditional term thereof the release of the Claiming Party from
all liability in respect of such Third Party Claim and (ii) results in the
imposition on the Claiming Party of any remedy other than money damages;
provided, however, that the Claiming Party shall not unreasonably withhold or
delay its consent to the entry of any judgment or any settlement of a Third
Party Claim. If the Indemnitor elects not to exercise its rights to assume
the defense 


                                      65
<PAGE>   70


of the Third Party Claim, or if injunctive relief is sought which would have 
an adverse effect on the Claiming Party, the Claiming Party may, but shall have
no obligation to, defend against such Third Party Claim or legal proceeding in
such manner as it may deem appropriate, and the Claiming Party may compromise or
settle such Third Party Claim and proceeding without the Indemnitor's consent so
long as the Claiming Party acts in a commercially reasonable manner (without
regard to the Claiming Party's indemnification rights hereunder).  The parties
agree that the right to jointly defend against any actions which may impact both
parties is hereby granted (provided that the party other than the Claiming Party
shall be solely liable for its costs and expenses in connection with such joint
defense), and it is understood that the Sellers shall incur the costs for
actions relating to PCS which occurred prior to Closing.
                          (c)  PAYMENT.  After any final judgment or award
shall have been rendered by a court, arbitration board or administrative agency
of competent jurisdiction and the time in which to appeal therefrom shall have
expired, or a settlement shall have been consummated, or the Claiming Party and
the Indemnitor shall arrive at a mutually binding agreement with respect to
each separate

                                      66
<PAGE>   71

matter alleged to be indemnified by the Indemnitor hereunder, the Claiming
Party shall forward to the Indemnitor notice of any sums due and owing by it
with respect to such matter (in accordance with Section 8.10 hereof) and the
Indemnitor shall pay all of the sums so owing to the Claiming Party  by wire
transfer, certified or bank cashier's check within 10 days after the date of
such notice.
                          (d)  ESCROW.  To the extent that the Escrow Amount
has not been released pursuant to the Escrow Agreement, the Buyer Indemnified
Party's right to  indemnification and to be held harmless pursuant to Section
7.3 hereof must first be asserted against the Escrow Amount.
                 7.9      CONSIDERATION ADJUSTMENT. Unless otherwise required by
law, the parties shall treat any payments made pursuant to this Article VII as
an adjustment to the Consideration for federal, state, and local income tax
purposes.

other action against such Seller instituted by the Buyer and relating to this

law, be irrevocable, unless and until a successor authorized agent acceptable
to the Buyer shall have been appointed by the Sellers, such successor shall
have accepted such appointment and written notice thereof shall have been given
to the Buyer.  Each Seller further agrees that service of process upon such
authorized agent or successor shall be deemed in every respect service of
process upon such Seller in any such suit, proceeding or other action.  Each
Seller further agrees to take any and all action, including the execution and
filing of all such instruments and documents, as may be necessary to continue

obligations hereunder to any Designated Subsidiary, PROVIDED, HOWEVER, that the

of (i) the number of PCS Phones as of the Closing Date over (ii) the PCS Phones

on demand such amounts as such Lender may determine to be reasonably necessary

determines are attributable to its making or maintaining Loans, or maintaining
Commitments hereunder or its obligation to make any such Loans hereunder, or
any reduction in any amount receivable by such Lender hereunder in respect of
any such Loans, Commitments or obligation, resulting from any Regulatory Change
which: (i) changes the basis of taxation of any amounts payable to such Lender
under this Agreement in respect of any of such Loans or Commitments (other than
taxes imposed on the overall net income of such Lender); or (ii) imposes or
modifies any reserve, special deposit, deposit insurance or assessment, minimum
capital, capital ratio or similar requirements relating to any extensions of
credit or other assets of, or any deposits with or other liabilities of, such
Lender or any holding company of such bank (including, without limitation, a
request or requirement which affects the manner in which any Lender or the
holding company of any thereof allocates capital resources to commitments,
including the Commitments and obligations of such Lender hereunder).  Each
Lender will notify the Borrower of any event occurring after the date of this
Agreement which will entitle such Lender to compensation pursuant to this
clause (a) as promptly as practicable after it obtains knowledge thereof and
determines to





                                       30
<PAGE>   37
request such compensation.

                 (b)      Without limiting the effect of the foregoing
provisions of this SECTION 2.4 (but without duplication), the Borrower shall
pay to each Lender from time to time upon demand by such Lender such amounts as
the Lender may determine to be reasonably necessary to compensate such Lender
for any costs which it determines are attributable to the maintenance by it or
its holding company, pursuant to any law or regulation of any jurisdiction or
any interpretation, directive or request (whether or not having the force of
law) of any court or governmental or monetary authority, whether in effect on
the date of this Agreement or thereafter, of capital in respect of its Loans or
its obligation to make the Loans hereunder (such compensation to include,
without limitation, an amount equal to any reduction in return on assets or
equity of such Lender or its holding company to a level below that which it
could have achieved but for such law, regulation, interpretation, directive or
request).  The Lender will notify the Borrower with a copy to the Agent) if it
is entitled to compensation pursuant to this clause (b) as promptly as
practicable after it determines to request such compensation.

                 (c)      Each notice delivered by any Lender pursuant to this
SECTION 2.4 shall contain a statement of such Lender as to any such additional
amount or amounts (including calculations thereof in reasonable detail) which
shall, in the absence of manifest error, be conclusive  of the matters stated
therein and be binding upon the Borrower.  In determining such amount, any
Lender may use any method of averaging and attribution that it in good faith
shall deem applicable.

                 (d)      Without prejudice to the survival of any other
agreement of the Borrower hereunder or under any other Loan Document, the
agreements and obligations of the Borrower contained in this SECTION 2.4 shall
survive the payment in full of principal, interest and other amounts payable
hereunder and under the Notes and the other Loan Documents.

                 (e)      Notwithstanding anything in this SECTION 2.4 to the
contrary, to the extent that notice is given by any Lender to the Borrower of
any additional amount owing to such Lender under this SECTION 2.4 more than 360
days after the occurrence of the event giving rise to such obligation, such
Lender shall not be entitled to compensation under this SECTION 2.4 for any
amounts incurred or accruing 360 days prior to the giving of such notice to
Borrower.

                 (f)      Upon the receipt by the Borrower from any Lender (an
"AFFECTED LENDER") of a claim for compensation pursuant to this SECTION 2.4 or
SECTION 3.5, the Borrower may (i) request one or more of the Lenders to acquire
all or part of such Affected Lender's Loans and Revolving Loan Commitment
(provided that no such other Lender shall have any obligation to so acquire or
assume all 





                                       31
<PAGE>   38
or any part of such Affected Lender's Loans and Revolving Loan
Commitment), or (ii) designate a Replacement Lender reasonably satisfactory to
the Agent.  Any such designation of a Replacement Lender under clause (ii)
shall be subject to the prior written consent of the Agent, which consent shall
not be unreasonably withheld.

                 SECTION 2.5.     INVESTMENT REPRESENTATIONS.  Each Lender
represents and warrants that it is holding its Notes for its own account, for
investment purposes and not with a view to distribution thereof; PROVIDED,
HOWEVER, that the foregoing representation shall not be construed as imposing
any limitation on such Lender's right to transfer or sell any Loans or Notes
that is not otherwise expressly set forth in this Agreement or required under
applicable law.  Each Lender agrees that it will not, directly or indirectly,
offer, transfer, sell, assign, pledge; hypothecate or otherwise dispose of any
of the Notes, any shares of Series B Preferred Stock or any Common Stock (or
solicit any offers to buy, purchase or otherwise acquire or take a pledge of
Notes, Series B Preferred Stock or Common Stock), except in compliance with the
Securities Act of 1933, as amended or otherwise modified from time to time.
Each Lender agrees that it will not transfer, sell, assign, pledge, hypothecate
or otherwise dispose of any Notes, Series B Preferred Stock or Common Stock if
any such disposition would cause the Borrower to be required to register any of
the foregoing pursuant to Section 12(g) of the Securities Exchange Act of 1934,
as amended or otherwise modified from time to time.

                 SECTION 3.1.     BORROWING PROCEDURE.  By delivering a
Borrowing Request to the Agent at the Agent's Atlanta Office on or before 11:00

time request, (i) in the case of Revolving A Loans, on not less than two (2)
Business Days' nor more than three (3) Business Days' notice and (ii) in the
case of Revolving B Loans, on not less than one (1) Business Day notice, that a
Borrowing of Revolving Loans be made on the Business Day specified in such
Borrowing Request.  The Borrowing Request shall specify whether such Borrowing
is to be made as Revolving A Loans or Revolving B Loans.  Borrowings of
Revolving A Loans shall be in a minimum aggregate amount equal to $250,000 and
in integral multiples of $50,000 or, if less, the amount of the Revolving A
Loan Availability immediately prior to





                                       32
<PAGE>   39
such Borrowing.  Borrowings of Revolving B Loans shall be in a minimum
aggregate amount equal to $50,000 and in integral multiples of $50,000 or, if
less, the amount of the Revolving B Loan Availability immediately prior to such
Borrowing.  Each Revolving Loan shall be made on the Business Day specified in
the Borrowing Request therefor (including the initial Revolving Loans to be
made on the Closing Date).  On the day prior to such Business Day specified by
the Borrower, each Lender shall, on or before 2:00 p.m., New York City time,
deposit same day funds with the Agent in an amount equal to such Lender's
Revolving Percentage of the requested Borrowing, such deposit to be made to
such account as the Agent shall specify from time to time by notice to the
Lenders.  On the Business Day specified by the Borrower in the Borrowing
Request, the proceeds of all Borrowings shall be made available to the Borrower
by wire transfer of such proceeds to such transferees, or to such accounts of
the Borrower, as the Borrower shall have specified in the Borrowing Request
therefor; PROVIDED, HOWEVER, that in each case the Agent shall be required to
make available to the Borrower the proceeds of any Borrowing only to the extent
received by it in same day funds from the Lenders.  No Lender's obligation to
make any Loan shall be affected by any other Lender's failure to make any Loan.

Loan, by a Term Note payable to the order of such Lender in a principal amount
equal to such Lender's Term Percentage of the Term Loan;

                 (b)      in the case of such Lender's Revolving A Loans, by a
Revolving A Note payable to the order of such Lender in a principal amount
equal to such Lender's Revolving Percentage of the Revolving A Loan Commitment
Amount; and

                 (c)      in the case of such Lender's Revolving B Loans, by a

equal to such Lender's Revolving Percentage of the Revolving B Loan Commitment
Amount.

The Borrower hereby irrevocably authorizes each Lender to make (or cause to be
made) appropriate notations on a grid schedule attached to such Lender's Notes
(or on a continuation of any such grid attached to any Note and made a part
thereof), which notations shall evidence, INTER ALIA, the date and outstanding
principal amount of the Loans evidenced thereby.  The notations on any such
grid (and on any such continuation) indicating the outstanding principal amount
of such Lender's Loans shall be presumptive evidence of the principal amount
thereof owing and unpaid, but the failure to record any such amount on any such
grid (or on any such continuation) shall not limit or otherwise affect the
obligations of the Borrower hereunder or under such Note to make payments of
principal of or interest on such Loans when due.

                 SECTION 3.3.     PRINCIPAL PAYMENTS.  Repayments and

management system required to be maintained by the Borrower under SECTION
6.1.17, make mandatory prepayments of the Revolving A Loans and the Revolving B

payment in full of all outstanding Revolving A Loans).

Unless expressly set forth to the contrary in this SECTION 3.3.1 or elsewhere
in the Agreement, any payments required to be made by the Borrower pursuant to
this SECTION 3.3.1 shall be applied to principal in the following order:

                 (i)      FIRST, to the payment in full of all outstanding
Revolving A Loans,

<PAGE>   43
the proceeds of borrowed funds or the issuance of debt securities, the Borrower
shall be required to pay to the Lenders prior to or concurrently with such
prepayment a Prepayment Fee in an amount equal to one percent (1%) of the
amount of the Loans as of the date of the prepayment.  Any Prepayment Fee shall
be paid by the Borrower to the Lenders as liquidated damages for the loss of
the bargain and shall not constitute a penalty.

                 SECTION 3.3.3.   REVOLVING LOANS ON BORROWER'S BEHALF. The
Lenders are authorized to, and at their option may, make Revolving Loans on
behalf of the Borrower for payment of all fees, expenses, charges, costs,
principal and interest owed by the Borrower to the Lenders or the Agent under
this Agreement and the other Loan Documents.  Such Revolving Loans shall be
made when and as the Borrower fails promptly to pay same, and all such
Revolving Loans shall constitute  Revolving Loans made to the Borrower and
shall be secured by all of the Collateral.  Following the making of any
Revolving Loans pursuant to this SECTION 3.3.3, such Lender shall promptly
notify the Borrower of the making of such Revolving Loans on the Borrower's
behalf and the aggregate principal amount of such Loans; PROVIDED THAT the
failure by any Lender to give such notice shall not affect the Borrower's
obligations under this Agreement or with respect to such Revolving Loans.

                 SECTION 3.3.4.  REDUCTION OF REVOLVING LOAN COMMITMENT.

                 (a)      The Borrower shall have the right, upon at least
thirty (30) days notice to the Agent, to reduce in whole or in part (ratably as
to all Lenders) the Revolving A Loan Commitment Amount and the Revolving B Loan
Commitment Amount, PROVIDED, HOWEVER, that the Revolving A Loan Commitment
Amount and the Revolving B Loan Commitment Amount of the Lenders shall not be
reduced to an amount which is less than the aggregate amount of the Revolving A
Loans and Revolving B Loans, respectively, then outstanding after giving effect
to any prepayments made in connection with such reduction, PROVIDED, FURTHER,
HOWEVER, that each partial reduction of the Revolving A Loan Commitment Amount
or the Revolving B Loan Commitment Amount shall be in an aggregate amount of
$1,000,000 or an integral multiple of $500,000 in excess  thereof (or, if less,
the entire amount thereof), and the Borrower shall pay any Prepayment Fee
required under SECTION 3.3.2.  Any notice given pursuant to this clause (a) of
SECTION 3.3.4 shall be irrevocable, and once the Revolving A Loan Commitment
Amount or the Revolving B Loan Commitment Amount, as the case may be, is
reduced pursuant to this clause (a) of SECTION 3.3.4, such amount thereafter
may not be reinstated or increased.  The Borrower shall not be permitted to
reduce the Revolving B Loan Commitment Amount unless the Revolving A Loan
Commitment Amount has been reduced to zero in accordance with the terms hereof.

                 (b)      The Revolving A Loan Commitment (and the Revolving A
Loan Commitment Amount) and the Revolving B Loan Commitment (and





                                       37
<PAGE>   44
the Revolving B Loan Commitment Amount) shall be permanently reduced by the
amount of Net Cash Proceeds received by the Borrower or any of its Subsidiaries
in connection with any sale or disposition of assets to the extent the net book
value of the asset(s) sold or disposed together with the net book value of all
other assets sold or disposed during the term of this Agreement exceeds
$250,000.  Any reduction pursuant to this clause (b) shall be applied first to
the Revolving A Loan Commitment Amount and then to the Revolving B Loan
Commitment Amount.

                 (c)      On September 15, 1996, the Revolving A Loan
Commitment (and the Revolving A Loan Commitment Amount) shall be permanently
reduced (ratably as to all Lenders) by an amount equal to the difference
between the Revolving A Loan Commitment Amount and the amount of Revolving A
Loans outstanding on such date.

                 (d)      The Revolving A Loan Commitment (and the Revolving A
Loan Commitment Amount) and the Revolving B Loan Commitment (and Revolving B
Loan Commitment Amount) shall be permanently reduced by the amount of any
prepayments required under clauses (c), (d), (e), (f), (g), (h) or (i) of
SECTION 3.3.1.  Any reduction pursuant to this clause (d) shall be applied
first to the Revolving A Loan Commitment Amount and then to the Revolving B
Loan Commitment Amount.

                 SECTION 3.4.     INTEREST.  Interest on the outstanding
principal amount of the Loans and other outstanding Obligations shall accrue
and be payable in accordance with this SECTION 3.4.

                 SECTION 3.4.1.   RATES.  Subject to SECTION 3.4.3, Borrowings
shall accrue interest at the ING Alternate Base Rate as in effect from time to
time PLUS 5.00%.

                 SECTION 3.4.2.   POST-DEFAULT RATES.  From and after the
occurrence of an Event of Default and during the continuance thereof, the
Borrower shall pay interest (after as well as before judgment) on the
outstanding principal amount of all Loans and other Obligations at a rate per
annum equal to the Post-Default Rate applicable to such Loans and Obligations.

                 SECTION 3.4.3.   PAYMENT DATES.  Accrued interest on the Loans
shall be payable, without duplication:

                 (a)      on Maturity;

                 (b)      with respect to any portion of any Loan prepaid or
repaid pursuant to SECTION 3.3.1, on the date of such prepayment or repayment
is due as provided in SECTION 3.3.1 and, in the case of a voluntary prepayment,
on the date set forth in any notice required for such prepayment; and

                 (c)      on each Monthly Payment Date, commencing with the

<PAGE>   45
first such day following the Closing Date.

applicable law, interest on overdue amounts (including overdue interest), shall

                 SECTION 3.4.4.   RATE DETERMINATIONS.  All determinations by
the Agent of the rate of interest applicable to any Loan shall be conclusive in
the absence of manifest error.

                 SECTION 3.5.     TAXES.  (a)  Any and all payments by the
Borrower hereunder or under the Notes or any other Loan Document shall be made,
in accordance with this SECTION 3.5, free and clear of and without deduction
for any and all present or future Taxes.  If the Borrower shall be required by
law to deduct any Taxes from or in respect of any sum payable hereunder or
under any Note to any Lender or the Agent, (i) the sum payable shall be
increased as may be necessary so that after making all required deductions
(including deductions applicable to additional sums payable under this SECTION
3.5), such Lender or the Agent (as the case may be) receives an amount equal to
the sum it would have received had no such deductions been made, (ii) the
Borrower shall make such deductions and (iii) the Borrower shall pay the full
amount deducted to the relevant taxation authority or other authority in
accordance with applicable law;

                 (b)      In addition, the Borrower agrees to pay any present
or future stamp or documentary taxes or intangibles taxes or any other excise
or property taxes, transfer taxes, charges or similar levies which arise from
any payment made hereunder or under the Notes or from the execution, delivery
or registration of, or otherwise with respect to this Agreement, the Notes, or
any other Loan Document;

                 (c)      The Borrower will indemnify each Lender and the Agent
for the full amount of the taxes, charges and levies described in clauses (a)
and (b) of this SECTION 3.5 (including, without limitation, any such taxes,
charges and levies imposed by any jurisdiction on amounts payable under this
SECTION 3.5) paid by such Lender or the Agent (as the case may be) and any
liability (including penalties, interest and expenses) arising therefrom or
with respect thereto, whether or not such taxes, charges and  levies were
correctly or legally asserted.  Payment under this clause (c) shall be made
within 10 days from the date such Lender or the Agent (as the case may be)
makes written demand therefor;

                 (d)      Within 10 days after the date of any payment of
Taxes, the Borrower will furnish to the Agent, at its address referred to in
SECTION 10.2, the original or a certified copy of any receipt received by the
Borrower evidencing payment thereof;

                 (e)      On or prior to the Closing Date and on or prior to





                                       39
<PAGE>   46
the first Business Day of each calendar year thereafter, each Foreign Lender
shall provide the Agent and the Borrower with two properly executed original
Forms 4224 and 1001 (or any successor form) prescribed by the Internal Revenue
Service or other documents satisfactory to the Borrower and the Agent, and
properly executed Internal Revenue Service Forms W-8 or W-9, as the case may
be, certifying (i) as to such Foreign Lenders's status for purposes of
determining exemption from United States withholding taxes with respect to all
payments to be made to such Foreign Lender hereunder and under the Notes or
(ii) that all payments to be made to such Foreign Lender hereunder and under
the Notes are subject to such taxes at a rate reduced to zero by an applicable
tax treaty.  Each Foreign Lender agrees to provide the Agent and the Borrower
with new forms prescribed by the Internal Revenue Service upon the expiration
or obsolescence of any previously delivered form, or after the occurrence of
any event requiring a change in the most recent forms delivered by it to the
Agent and the Borrower;

                 (f)      In the event that the Agent or any Lender receives a
refund of any taxes paid on its behalf by the Borrower in accordance with this
SECTION 3.5, the Agent or such Lenders, as the case may be, shall pay such
refund to the Borrower; and

                 (g)      Without prejudice to the survival of any other
agreement hereunder, the agreements and obligations contained in this SECTION
3.5 shall survive the payment in full of principal and interest hereunder and
under the Notes.

                 SECTION 3.6.     PAYMENTS, INTEREST RATE COMPUTATIONS, OTHER
COMPUTATIONS, ETC.  All payments by the Borrower pursuant to this Agreement,
the Notes or any other Loan Document,  in respect of principal or interest on
the Notes shall be made by the Borrower to the Agent for the account of the
Lenders, PRO RATA according to their respective unpaid principal amounts of the
Notes.  The payment of the commitment fee referred to in SECTION 2.3 shall be
made by the Borrower to the Agent for the account of the Lenders PRO RATA
according to their respective Revolving Percentages.  All other amounts payable
to the Agent or any Lender under this Agreement or any other Loan Document
(except under SECTION 2.4) shall be paid to the Agent for the account of the
Person entitled thereto.  All such payments required to be made to the Agent
shall be made, without setoff, deduction or counterclaim, not later than 2:00
p.m., New York City time, on the  date due, in immediately available funds, to
the Collection Account.  Funds received after that time shall be deemed to have
been received by the Agent on the next following Business Day.  The Agent shall
promptly remit in the type of funds received to each Lender notified to the
Agent its share, if any, of such payments received by the Agent for the account
of such Lender or holder.  All interest and fees shall be computed on the basis
of the actual number of days (including the first day but excluding the last
day) occurring during the period for which such interest or fee is payable over
a year comprised of





                                       40
<PAGE>   47
360 days.  Whenever any payment to be made shall otherwise be due on a day
which is not a Business Day, such payment shall be made on the immediately
preceding Business Day.  For purposes of determining the Revolving A Loan
Availability and the Revolving B Loan Availability (a) all payments (including
cash sweeps) consisting of cash, wire, or electronic transfers in immediately
available funds shall be deemed received by the Agent on the day of deposit in
the Collection Account and notice to the Agent of such deposit, and (b) all
payments consisting of checks, drafts, or similar noncash items shall be deemed
received on the day of receipt of good funds following deposit in the
Collection Account (together with notice to the Agent of such deposit).  For
the purposes of computing interest and fees hereunder, all payments received in
the form of cash sweeps from the Concentration Accounts will be credited on the
Business Day following the day on which such payments are deemed received for
purposes of the preceding sentence.

                 SECTION 3.7.     PRORATION OF PAYMENTS.  If any Lender shall
obtain any payment or other recovery (whether voluntary, involuntary, by
application of setoff or otherwise) on account of principal of or interest on
any Loan or other Obligations in excess of such Lender's or holder's PRO RATA
share of payments then or therewith obtained thereon by all Lenders, such
Lender which has received in excess of its PRO RATA share shall purchase from
the other Lenders such participations in such Notes or other Obligations held
by them as shall be necessary to cause such purchaser to share the excess
payment or other recovery ratably with each of them; PROVIDED, HOWEVER, that if
all or any portion of the excess payment or other recovery is thereafter
recovered from such purchasing holder, the purchase shall be rescinded and the
purchase price restored to the extent of such recovery, but without interest.
The Borrower agrees that any Lender so purchasing a participation from another
Lender pursuant to this SECTION 3.7 may, to the fullest extent permitted by
law, exercise all its rights of payment (including pursuant to SECTION 3.8)
with respect to such participation as fully as if such Lender were the direct
creditor of the Borrower in the amount of such participation.  If under any
applicable bankruptcy, insolvency or other similar law, any Lender receives a
secured claim in lieu of a setoff to which this SECTION 3.7 applies, such
Lender shall, to the extent practicable, exercise its rights in respect of such
secured claim in a manner consistent with the rights of the Lenders under this
SECTION 3.7 to share in the benefits of any recovery on such secured claim.

                 SECTION 3.8.     SETOFF.  In addition to and not in limitation
of any rights of any Lender under applicable law, each Lender shall, upon the
occurrence and during the continuance of any Event of Default, have the right
to appropriate and apply to the payment of the Obligations owing to it (whether
or not then due), and (as security for such Obligations) the Borrower hereby
grants to each Lender, a continuing security interest in, any and all





                                       41
<PAGE>   48
balances, credits, deposits, accounts or moneys of the Borrower then or
thereafter maintained with such Lender; PROVIDED, HOWEVER, that any such
appropriation and application shall be subject to the provisions of SECTION
3.7.  Following any such appropriation and application pursuant to this SECTION
3.8, such Lender shall promptly provide the Borrower with notice of such
appropriation and application and the amount applied, provided, that the
failure by any Lender to give any such notice shall not affect the obligations
of the Borrower or impair any right of any Lender under this Agreement or
subject any Lender to any liability.

                 SECTION 3.9.     USE OF PROCEEDS.

                 (a)      The Borrower shall use the proceeds of the Term Loan
and the Revolving A Loans and Revolving B Loans made on the Closing Date (i) to
pay a portion of the "Consideration" (as such term is defined in each of the
Acquisition Agreements), (ii) to pay costs and expenses arising in connection
with the transactions contemplated hereby which are set forth in ITEM 1
("Transaction Costs") of the Disclosure Schedule (subject to the Required
Lenders' approval of such costs and expenses), (iii) to refinance certain
existing Indebtedness as listed on ITEM 3 ("Indebtedness to be Refinanced") of
the Disclosure Schedule, all as more specifically described in ITEM 2 ("Sources
and Uses") of the Disclosure Schedule, and (iv) to finance its general working
capital needs.

                 (b)      The Borrower shall use the proceeds of (i) the
Revolving A Loans made after the Closing Date to finance acquisitions
(PROVIDED, HOWEVER, that this clause (i) shall not be construed to permit any
acquisitions which are otherwise prohibited by the terms of this Agreement or
the other Loan Documents), and (ii) the Revolving B Loans made after the
Closing Date to finance its continuing working capital needs; PROVIDED,
HOWEVER, that the Revolving B Loans shall not be used to repay any other
outstanding Loan.

                 (c)      No part of the proceeds of any Loans shall be used
for any purpose which violates Regulations G, T, U or X of the F.R.S. Board.

whomsoever with respect to any employee benefit plan, fund, program,
arrangement, agreement

or commitment described in clause (i) or (ii) of the immediately preceding
sentence.

                 (b)      No Reportable Event which could result in a Material
Adverse Change has occurred during the six-year period prior to the date on
which this representation is made or deemed made with respect to any Single
Employer Plan.  The Borrower, each Commonly Controlled Entity, each Subsidiary,
each Plan, and each trust maintained pursuant to any such Plan have complied in
all material respects with the applicable provisions of ERISA, the IRC, and any
other applicable laws.  Except as disclosed in ITEM 7 ("Benefit Plans") of the
Disclosure Schedule, the present value of all "benefit liabilities" (within the
meaning of Section 4001(a)(16) of ERISA) under each Single Employer Plan
maintained by the Borrower, any Subsidiary or any Commonly Controlled Entity
(based on those assumptions that would be used in a termination of each such
Plan) did not, as of the last annual valuation date for which an actuarial
valuation report has been done, exceed the value of the assets of such Plan as
of such date.  Except as disclosed in such ITEM 7, neither the Borrower nor any
Commonly Controlled Entity or Subsidiary has incurred any liability to the PBGC
or to any other Person under Section 4062, 4063 or Section 4064 of ERISA on
account of the termination of, or its withdrawal from, a Single Employer Plan,
and no Lien has been imposed on the assets of the Borrower or any Commonly
Controlled Entity or Subsidiary under Section 4068 of ERISA.  To the knowledge
of the Borrower and any Commonly Controlled Entities and Subsidiaries, there
does not exist any event or condition which would permit the institution of
proceedings to terminate any Single Employer Plan pursuant to Section 4042 of
ERISA.  Except as disclosed in ITEM 7 of the Disclosure Schedule, no
"accumulated funding deficiency" (as defined in Section 302 of ERISA or Section
412 of IRC), whether or not waived, exists with respect to any Pension Plan.
The Borrower and each Commonly Controlled Entity and Subsidiary have timely
made in full each quarterly installment payment to any Pension Plan required
under Section 302(e) of ERISA or Section 412(m) of the IRC and have also made
full and timely payment of any other costs or expenses related to such a Plan.
The Borrower and all Commonly Controlled Entities and Subsidiaries have made
full and timely payment of all contributions to Multiemployer Plans required
under ERISA, the IRC or applicable collective bargaining agreements.  Neither
the Borrower nor any Commonly Controlled Entity or Subsidiary has had a
complete or partial withdrawal from any Multiemployer Pension Plan and the
liability to which the Borrower or any Commonly Controlled Entity or Subsidiary
would become subject under ERISA if the Borrower or any such Commonly
Controlled Entity or Subsidiary were to withdraw completely from all
Multiemployer Pension Plans as of the valuation date most closely preceding the
date hereof is not in excess of $100,000.  No such Multiemployer Pension Plan
has been terminated or is in Reorganization or Insolvent, nor, to the knowledge
of the Borrower and any Commonly Controlled Entities and Subsidiaries, is any
such





                                       55
<PAGE>   62
Multiemployer Pension Plan likely to be terminated or to become in
Reorganization or Insolvent.  To the  knowledge of the Borrower and any
Commonly Controlled Entities and Subsidiaries, no "accumulated funding
deficiency" (as defined in Section 302 of ERISA or Section 412 of the IRC),
whether or not waived, exists with respect to any Multiemployer Plan.  The
present value (determined using assumptions which are reasonable in respect of
the benefits provided and the employees participating) of the aggregate
liability of the Borrower and each Subsidiary and Commonly Controlled Entity
for post-retirement benefits to be provided to their current and former
employees under Plans which are welfare benefit plans (as defined in Section
3(1) of ERISA) is not in excess of $100,000.  No written notice of liability
has been received with respect to the Borrower, any of its Subsidiaries, or any
Plan for any "prohibited transaction" (within the meaning of Section 4975 of
the IRC or Section 406 of ERISA), nor has any such prohibited transaction
resulting in material liability to the Borrower, any of its Subsidiaries
occurred.  Neither the Borrower nor any Subsidiary or Commonly Controlled
Entity will, as a result of consummating the transactions contemplated by this
Agreement (pursuant to the provisions of the Agreement, by operation of law or
otherwise) (i) have incurred or become liable for any tax assessed by the
Internal Revenue Service for any alleged violations of Section 4975 of the IRC
or any civil penalty imposed by the Department of Labor for any alleged
violations of Section 406 of ERISA, (ii) have caused or permitted to occur any
"prohibited transaction" within the meaning of such Section 4975 of the IRC or
Section 406 of ERISA with respect to any Plan for which no exemption is
available or (iii) have incurred any liability to the PBGC (other than ordinary
and usual PBGC premium liability) or any liability for complete or partial
withdrawal to any Multiemployer Plan.  Neither the Borrower nor any Subsidiary
is subject (directly or indirectly) to, and no facts exist which could subject
the Borrower or any Subsidiary (directly or indirectly) to, any other
liability, penalty, tax or lien whatsoever, which could result in a Material
Adverse Change and which is directly or indirectly related to any Plan,
including, but not limited to, liability for any damages or penalties arising
under Title I or Title IV of ERISA, liability for any tax or penalty resulting
from a loss of deduction under Section 404 or 419 of the IRC, any tax or
penalty under chapter 43 of the IRC, or any taxes or penalties under any other
applicable law, but excluding any liability to make contributions or pay
premiums to or under an ongoing Plan before the last due date on which such
contributions or premiums could be paid or made without penalty or to pay
benefits when due in accordance with Plan terms.

                 SECTION 5.12.    LABOR CONTROVERSIES.  Except as disclosed in
ITEM 8 ("Labor Controversies") of the Disclosure Schedule, there are no labor
controversies pending or, to the best knowledge of the Borrower, threatened,
relating to the Borrower or any Subsidiary.  There is (i) no unfair labor
practice complaint pending against the





                                       56
<PAGE>   63
Borrower, or any of its Subsidiaries or, to the best knowledge of the Borrower,
threatened against any of them, before the National Labor Relations Board, and
no  grievance  or arbitration proceeding arising out of or under any collective
bargaining agreement is so pending against the Borrower or any of its
Subsidiaries or, to the best knowledge of the Borrower, threatened against any
of them, (ii) no strike, labor dispute, slowdown or stoppage is pending against
the Borrower or any of its Subsidiaries or, to the best knowledge of the
Borrower, threatened against the Borrower or any of its Subsidiaries and (iii)
no union representation question existing with respect to the employees of the
Borrower or any of its Subsidiaries.  Each of the Borrower and its Subsidiaries
is in compliance in all material respects with all collective bargaining
agreements to which it is subject.

                 SECTION 5.13.    OWNERSHIP OF PROPERTIES; COLLATERAL.

                 (a) Each of the Borrower and its Subsidiaries shall own good
title to all of its material personal properties and assets of any nature
whatsoever, free and clear of all Liens except as permitted pursuant to SECTION
6.2.3.

                 (b)      Except to the extent otherwise consented to in
writing by the Required Lenders, the provisions of the Security Agreement are
effective to create in favor of the Agent for the benefit of the Agent and the
Lenders, a legal, valid and enforceable security interest in all right, title
and interest of the Loan Parties in the Collateral described therein, and, upon
the filing of the Financing Statements and any required filing in the United
States Patent and Trademark Office pursuant to SECTION 4.1.13, the Security
Documents will create a fully perfected first priority security interest in all
right, title and interest of the Loan Parties in all of the Collateral
described therein, to the extent that a security interest therein can be
perfected by such a filing, subject to no other Liens other than Liens
permitted by SECTION 6.2.3.

                 SECTION 5.14.    INTELLECTUAL PROPERTY.  Each of the Borrower
and its Subsidiaries owns or licenses all such Intellectual Property, and has
obtained assignments of all licenses and other rights, as the Borrower
considers necessary for or as are otherwise material to the conduct of the
business of the Borrower and its Subsidiaries as now conducted without,
individually or in the aggregate, any infringement upon rights of other Persons
which could result in a Material Adverse Change.  All Intellectual Property
owned or licensed from third Persons described in this SECTION 5.14 is set
forth in ITEM 9 ("Intellectual Property") of the Disclosure Schedule.

                 SECTION 5.15.    ACCURACY OF INFORMATION.  All factual

document or statement furnished to the Agent or any of the Lenders by or on
behalf of the Borrower contains any untrue statement of a material fact or

contained herein or therein not materially misleading.

                 SECTION 5.16.    INSURANCE.  All policies of insurance in

other Loan Documents or the authorization or issuance of Series B Special

any preemptive rights.  Except as set forth in Item 24 (Preemptive Rights,
Options, Warrants) of the Disclosure Schedule, no issued, no authorized but
unissued and no treasury shares of capital stock of the Borrower are subject to
any preemptive right, option, warrant, right of conversion or purchase or any

the Securities Act or any applicable state securities laws.

                 SECTION 5.32.    NO CONFLICT.  None of the transactions
contemplated by this Agreement or any of the other Loan Documents (including
the issuance of shares of Series B Special Preferred  Stock upon conversion of
Notes or shares of Common Stock upon conversion of the Series B Special
Preferred Stock) will give rise to any payment or the acceleration of any

conditions, if any, could subject the Borrower or any Subsidiary (directly or

such Lender's option, any time prior to the satisfaction in full of all of the
outstanding principal under and accrued interest on such Lender's Term Note or
Term Notes, convert its Term Note or Term Notes, in whole or in part (in
amounts of $100,000 or integral multiples thereof), at 100% of the amount so
converted, into fully paid and non-assessable shares of Series B Special
Preferred Stock at a rate (the "CONVERSION RATE") of 833.3333 shares of Series
B Special Preferred Stock for each $100,000 of outstanding principal and
accrued interest so converted.  All outstanding principal under and accrued
interest on the Term Notes may be converted as provided herein.

                 SECTION 8.2.     CONVERSION PROCEDURE.

                 (a)      To convert a Term Note or portion thereof, a Lender
must (i) complete and sign the notice set forth as Exhibit G hereto, (ii)
surrender such Term Note to the Borrower and (iii) furnish appropriate
endorsements and transfer documents if reasonably required by the Borrower.

                 (b)      As promptly as practicable after the surrender of a
Term Note in compliance with this SECTION 8.2, the Borrower shall issue and
deliver to the Lender so surrendering such Term Note, or on such Lender's
written order, a certificate of certificates for the number of whole and
fractional shares of Series B Special Preferred Stock issuable upon the
conversion of such Term Note or portion thereof in accordance with the
provisions of this Article 8.  If a Term Note shall be surrendered for partial
conversion, the Borrower shall execute and deliver to the Lender so
surrendering such Term Note without charge to such Lender, a new Term Note in
an





                                       85
<PAGE>   92
aggregate principal amount equal to the unconverted portion of the surrendered
Term Note with no other changes in or to the terms thereof.

                 (c)      Each conversion shall be deemed to have been effected
on the date on which the Term Note shall have been surrendered in compliance
with this SECTION 8.2, and the Person in whose name any certificate or
certificates issuable upon such conversion shall be deemed to have become on
said date the holder of record of the shares represented thereby; provided,
however, that any such surrender on any date when the stock transfer books of
the Borrower shall be closed shall constitute the Person in whose name the
certificates are to be issued as the record holder  thereof for all purposes on
the next succeeding day on which such stock transfer books are open, but such
conversion shall be at the Conversion Price in effect on the date upon which
the Term Note shall have been surrendered.  The Borrower shall deliver
certificates for shares of Series B Special Preferred Stock reflecting such
conversion as directed by the converting Lender not later than 48 hours after
the surrender of the Term Note in accordance herewith.

                 SECTION 8.3.  EFFECT ON RECLASSIFICATION, CONSOLIDATION,
MERGER OR SALE.  In the event of (i) any reclassification or change of
outstanding shares of Borrower Common Stock (other than a change in par value,
or from par value to no par value, or from no par value to par value, or as a
result of subdivision or combination), (ii) any consolidation, merger or
combination of the Borrower with another corporation or entity as a result of
which holders of shares of Borrower Common Stock shall be entitled to receive
securities or other property (including cash) with respect to or in exchange
for such shares or (iii) any sale or conveyance of the property of the Borrower
as, or substantially as, an entirety to any other corporation or entity as a
result of which holders of shares of Common Stock shall be entitled to receive
securities or other property (including cash) with respect to or in exchange
for such shares, then the Borrower or the successor or purchasing corporation
or entity, as the case may be, shall enter into a supplemental agreement
providing that the Term Notes shall be convertible into the kind and amount of
securities or other property (including cash) receivable upon such
reclassification, exchange, consolidation, merger, combination, sale or
conveyance by a holder of a number of shares issuable upon conversion of the
Term Notes immediately prior to such reclassification, exchange, consolidation,
merger, combination, sale or conveyance.  Such supplemental agreement shall
provide for adjustments which shall be as nearly equivalent as may be
practicable to the adjustments provided for in this Article 8.  The above
provision of this SECTION 8.3 shall similarly apply to successive
reclassifications, exchanges, consolidations, mergers, combinations, sales or
conveyances.

                 SECTION 8.4.     TAXES ON SHARES ISSUED.  The issuance of stock
certificates on conversions of the Term Notes shall be made without charge to
the converting Lender for any tax in respect of the issuance thereof.  The
Borrower shall not, however, be required to pay any tax which may be payable in
respect of any transfer involved in the issue and delivery of a stock
certificate in any name other than that of the converting Lender.

Notes that may be outstanding under this Agreement.

                 (b)      The Borrower covenants that all shares of Series B
Special Preferred Stock which may be issued upon conversion of Term Notes will
upon issuance be fully paid and nonassessable by the Borrower and free from all
taxes, liens and charges with respect to the issue thereof.

                 (c)      The Borrower covenants that if any shares to be
provided for the purpose of conversion of Term Notes require registration with
or approval of any governmental authority under any applicable federal or state
law (excluding federal or state securities laws) before such shares may be
validly issued upon conversion, the Borrower will in good faith and as
expeditiously as possible endeavor to secure such registration or approval, as
the case may be.

                 (d)      The Borrower covenants that if at any time shares of
Common Stock shall be listed on the New York Stock Exchange or any other
national securities exchange or on the Nasdaq Stock Market, the Borrower will,
if permitted by the rules of such exchange or market list and keep listed so

                 SECTION 8.6.     NOTICE TO LENDERS PRIOR TO CERTAIN ACTIONS.
In the event:

                 (a)      the Borrower shall declare a dividend (or any other
distribution) on its shares (other than in cash out of retained earnings); or

                 (b)     the Borrower shall authorize the granting to the 
holders of its shares generally of rights or warrants to subscribe for or

or

                                       87
<PAGE>   94
                 (c)      of any reclassification of shares of the Borrower
(other than a subdivision or combination of its outstanding shares, or a change
in par value, or from par value to no par value, or from par value to par
value), or of any consolidation or merger to which the Borrower is a party and
for which approval of any shareholders of the Borrower is required, or of the

                 (d)      of the voluntary or involuntary dissolution,

the date as of which the holders of shares of record to be entitled to such
dividend, distribution, rights or warrants are to be determined, or (y) the
date on which such reclassification, consolidation, merger, sale, transfer,
dissolution, liquidation or winding-up is expected to become effective or
occurring and the date as of which it is expected that holders of shares of

                                   ARTICLE 9.

                                   THE AGENT

                 SECTION 9.1.     ACTIONS.  Each Lender and the  holder of each
Note authorize the Agent to act on behalf of such Lender or holder under this
Agreement and any other Loan Document and, in the absence of other written
instructions from the Required Lenders received from time to time by the Agent
(with respect to which the Agent agrees that it will, subject to the last two
sentences of this SECTION 9.1, comply, except as otherwise reasonably advised
by counsel), to exercise such powers hereunder and thereunder as are
specifically delegated to or required of the Agent by the terms hereof and
thereof, together with such powers as may be reasonably incidental thereto.
Each Lender (including, without limitation, ING in its capacity as a Lender)
agrees (which agreement shall survive any termination of  this Agreement) to
indemnify the Agent, severally but not jointly PRO RATA according to such
Lender's aggregate percentage of the Revolving Loan Commitments and the
principal amount of outstanding Term Loans, from and against any and all
liabilities, obligations, losses, damages, penalties, actions, judgments,
suits, costs, expenses or disbursements of any





                                       88
<PAGE>   95
kind or nature whatsoever which may at any time be imposed on, incurred by, or
asserted against the Agent in any way relating to or arising out of this
Agreement, the Notes, or any other Loan Document, including the reimbursement
of the Agent for all out-of-pocket expenses (including attorneys' fees)
incurred by the Agent hereunder or in connection herewith or in enforcing the
Obligations of the Borrower under this Agreement or any other Loan Document, in
all cases as to which the Agent is not reimbursed by the Borrower; PROVIDED
that no Lender shall be liable for the payment of any portion of such
liabilities, obligations, losses, damages, penalties, actions, judgments,
suits, costs, expenses or disbursements determined by a court of competent
jurisdiction in a final proceeding to have resulted primarily from the Agent's
gross negligence or wilful misconduct.  Notwithstanding any other provision of
this Agreement to the contrary, the Agent shall not be required to take any
action hereunder or under any other Loan Document, or to prosecute or  defend
any suit in respect of this Agreement or any other Loan Document, unless it is
indemnified to its reasonable satisfaction by the Lenders against loss, costs,
liability and expense.  If any indemnity in favor of the Agent shall become
impaired, it may call for additional indemnity and cease to do the acts
indemnified against until such additional indemnity is given.

                 SECTION 9.2.     FUNDING RELIANCE, ETC.  Unless the Agent
shall have been notified by telephone, confirmed in writing, by any Lender by
5:00 p.m., New York City time, on the day prior to a Borrowing that such Lender
will not make available the amount which would constitute its Revolving
Percentage of such Borrowing on the date specified therefor, the Agent may
assume that such Lender has made such amount available to the Agent and, in
reliance upon such assumption, make available to the Borrower a corresponding
amount; PROVIDED, HOWEVER, that the Agent shall have no obligation to do so.
If such amount is made available by such Lender to the Agent on a date after
the date of such Borrowing, such Lender shall pay to the Agent on demand
interest on such amount at the Federal Funds Rate for the number of days from
and including the date of such Borrowing to the date on which such amount
becomes immediately available to the Agent, together with such other
compensatory amounts as may be required to be paid by such Lender to the Agent
pursuant to the Rules for Interbank Compensation of the Council on
International Banking or the Clearinghouse Compensation Committee, as the case
may be, as in effect from time to time.  A statement of the Agent submitted to
any Lender with respect to any amounts owing under this SECTION 9.2 shall be
conclusive, in the absence of manifest error.  If such amount is not in fact
made available to the Agent by such Lender within three Business Days after the
date of such Borrowing, the Agent shall be entitled to recover such amount,
with interest thereon at the rate per annum then applicable to the Loans
comprising such Borrowing, within five Business Days after demand, from the
Borrower.

<PAGE>   96
                 SECTION 9.3.     EXCULPATION.  Neither the Agent nor any of
its directors, officers, employees or agents shall be liable to any Lender for
any action taken or omitted to be taken by it under this Agreement, the Notes,
or any Loan Document, or in connection herewith or therewith, except for its
own wilful misconduct or gross negligence.  The Agent shall not be responsible
to any Lender for any recitals, statements, representations or warranties
herein or in any certificate or other document delivered in connection herewith
or for the authorization, execution, effectiveness, genuineness, validity,
enforceability, perfection, collectibility, or sufficiency of any of the Loan
Documents, the financial condition of the Borrower or any Subsidiary or the
condition or value of any of the Collateral, or be required to make any inquiry
concerning either the performance or observance of any of the terms, provisions
or conditions of any of the Loan Documents, the financial condition of the
Borrower or any Subsidiary or the existence or possible existence of any
Default.  The Agent shall be entitled to rely upon advice of counsel
concerning legal matters and upon any notice, consent, certificate, statement
or writing which it believes to be genuine and to have been presented by a
proper Person.

                 SECTION 9.4.     SUCCESSOR.  The Agent may resign as such at
any time upon at least thirty (30) days' prior notice to the Borrower and all
Lenders, such resignation not to be effective until a successor Agent is in
place.  The Agent shall be required to resign, upon the written request of the
Required Lenders, if it holds less than $10,000,000 of the Loans and
Commitments outstanding; PROVIDED, HOWEVER, that the Agent shall not be
required to resign pursuant to the terms of this sentence if the Agent's
Revolving Percentage plus its Term Percentage is equal to or greater than that
of each other Lender.  If the Agent at any time resigns, the Required Lenders
may appoint another Lender as a successor Agent which shall thereupon become
the Agent hereunder.  If no successor Agent shall have been so appointed by the
Required Lenders, and shall have accepted such appointment, within 30 days
after the retiring Agent's giving notice of resignation, then the retiring
Agent may, on behalf of the Lenders, appoint a successor Agent, which shall be
one of the Lenders or a financial institution reasonably acceptable to the
Borrower organized under the laws of the United States and having a combined
capital and surplus of at least $500,000,000.  Upon the acceptance of any
appointment as Agent hereunder by a successor Agent, such successor Agent shall
be entitled to receive from the retiring Agent such documents of transfer and
assignment as such successor Agent may reasonably request, and shall thereupon
succeed to and become vested with all rights, powers, privileges, and duties of
the retiring Agent, and the retiring Agent shall be discharged from its duties
and obligations under this Agreement and the other Loan Documents.

                 SECTION 9.5.     LOANS BY THE AGENT.  The Agent shall have the
same rights and powers with respect to (a) the Loans made by it 




                                       90
<PAGE>   97
or any of its Affiliates and (b) the Notes held by it or any of its Affiliates,
as any Lender and may exercise the same as if it were not the Agent.

                 SECTION 9.6.     CREDIT DECISIONS.  Each Lender acknowledges
that it has, independently of the Agent and each other Lender, and based on
such financial information and such other documents, information and
investigations as it has deemed appropriate, made its own credit decision to
extend its Commitments, and to make the Loans.  Each Lender also acknowledges
that it will, independently of the Agent and each other Lender, and based on
such other documents, information and investigations as it shall deem
appropriate at any time, continue to make its own credit decisions as to
exercising or not exercising from time to time any rights and privileges
available to it under this Agreement or any other Loan Document.

                 SECTION 9.7.     COPIES, ETC.  The Agent shall give prompt
notice to each Lender of each notice or request required or permitted to be
given to the Agent by the Borrower pursuant to the terms of this Agreement.
The Agent will distribute to each Lender each Instrument received for its
account and copies of all other communications received by the Agent from the
Borrower for distribution to the Lenders by the Agent in accordance with the
terms of this Agreement.  Notwithstanding anything herein contained to the
contrary, all notices to and communications with the Borrower under this
Agreement and the other Loan Documents shall be effected by the Lenders through
the Agent.

                                 MISCELLANEOUS

                 SECTION 10.1.    WAIVERS, AMENDMENTS, ETC.

                 (a)      The provisions of this Agreement and of each Loan
Document may from time to time be amended, modified or waived, if such
amendment, modification or waiver is in writing and, (x) in the case of an
amendment or modification, is consented to by the Borrower and the Required
Lenders or (y) in the case of a waiver of any obligation of the Borrower or
compliance with any prohibition contained in this Agreement, is consented to by
the Required Lenders; PROVIDED, HOWEVER, that no such amendment, modification
or waiver:

                 (i)      which would modify any requirement hereunder that any
         particular action be taken by all the Lenders or by the Required 
         Lenders shall be effective unless consented to by each Lender;  
                                                        

                 (ii)     which would modify this SECTION 10.1, change the





                                       91
<PAGE>   98
definition of "Required Lenders," increase the Revolving Loan Commitment Amount
or change any Revolving Percentage or Term Percentage for any Lender, reduce
any fees payable to the Lenders described in ARTICLE 2 and ARTICLE 3, extend
the Revolving Loan Commitment Termination Date or subject any Lender to any
additional obligations shall be made without the consent of each Lender;

            (iii)         which would extend the due date for, or reduce the
         amount of, any payment or prepayment of principal of or interest on
         any Loan (or reduce the principal amount of or rate of interest on any
         Loan) shall be made without the consent of the holder of the Note
         evidencing such Loan; or

             (iv)         which would affect adversely the interests, rights,
         compensation or obligations of the Agent QUA the Agent shall be made
         without consent of the Agent.

                 (b)      No failure or delay on the part of the Agent, any
Lender or the holder of any Note in exercising any power or right under this
Agreement or any other Loan Document shall operate as a  waiver thereof, nor
shall any single or partial exercise of any such power or right preclude any
other or further exercise thereof or the exercise of any other power or right.
No notice to or demand on the Borrower in any case shall entitle it to any
notice or demand in similar or other circumstances.  No waiver or approval by
the Agent, any Lender, or the holder of any Note under this Agreement or any
other Loan Document shall, except as may be otherwise stated in such waiver or
approval, be applicable to subsequent transactions.  No waiver or approval
hereunder shall require any similar or dissimilar waiver or approval thereafter
to be granted hereunder.

                 (c)      Neither any Lender nor the Agent shall be under any
obligation to marshal any assets in favor of the Borrower or any other party or
against or in payment of any or all of the Obligations.  Recourse for security
shall not be required at any time.  To the extent that the Borrower makes a
payment or payments to the Agent or the Lenders, or the Agent or the Lenders
enforce their security interests or exercise their rights of setoff, and such
payment or payments or the proceeds of such enforcement or setoff or any part
thereof are subsequently for any reason invalidated, set aside or required to
be repaid to a trustee, receiver or any other party under any bankruptcy law,
state or federal law, common law or equitable cause, then to the extent of such
recovery, the obligation or part thereof originally intended to be satisfied,
and all Liens, rights and remedies therefor, shall be revived and continued in
full force and effect as if such payment had not been made or such enforcement
or setoff had not occurred.

                 SECTION 10.2.    NOTICES.  All notices hereunder shall be

Person; any Environmental Liabilities and Costs related to any  property owned,

relating to any of the foregoing, whether or not the Agent or any Lender (or
any of their respective officers, directors, partners, employees or agents) is
a party thereto;

EXCEPT FOR any such Indemnified Liabilities arising for the account of a
particular Lender Party by reason of the relevant Lender Party's bad faith,
gross negligence or wilful misconduct as determined by a final and
nonappealable decision of a court of competent jurisdiction.  If and to the
extent that the foregoing undertaking may be unenforceable for any reason, the
Borrower hereby agrees to make the maximum contribution to the payment and
satisfaction of each of the Indemnified Liabilities which is permissible under
applicable law.  The foregoing indemnity shall become effective immediately
upon the execution and delivery hereof and shall remain operative and in full
force and effect notwithstanding the consummation of the transactions
contemplated hereunder, the repayment of any of the Loans made hereunder, the
invalidity or unenforceability of any term or provision of this Agreement or
any other Loan Document, or any investigation made by or on behalf of any
Lender or the Agent.

                 SECTION 10.5.    SURVIVAL.  The obligations of the Borrower
under SECTIONS 2.4, 3.5, 10.3 and 10.4, and the obligations of the Lenders
under SECTION 9.1, shall in each case survive any termination of this
Agreement.  The representations and warranties made by the Borrower in this
Agreement, the Notes and in each other Loan Document shall survive the
execution and  deliver of this Agreement, the Notes and each such other Loan
Document.

                 SECTION 10.6.    SEVERABILITY.  Any provision of this
Agreement, the Notes or any other Loan Document which is prohibited or
unenforceable in any jurisdiction shall, as to such jurisdiction, be
ineffective to the extent of such prohibition or unenforceability without
invalidating the remaining provisions of this Agreement, the Notes or such
other Loan Document or affecting the validity or enforceability of such
provision in any other jurisdiction.

                 SECTION 10.7.    HEADINGS.  The various headings of this
Agreement, the Notes and of each other Loan Document are inserted for
convenience only and shall not affect the meaning or interpretation of this
Agreement, the Notes or such other Loan Document or any provisions hereof or
thereof.

                 SECTION 10.8.    COUNTERPARTS, EFFECTIVENESS, ETC.  This
Agreement may be executed by the parties hereto in several counterparts, each
of which shall be executed by the Borrower and the Agent and be deemed to be an
original and all of which shall constitute together but one and the same
agreement.  This Agreement shall become effective when counterparts hereof
executed on behalf of the Borrower and each Lender (or notice thereof
satisfactory to the Agent) shall have been received by the Agent and notice
thereof





                                       96
<PAGE>   103
shall have been given by the Agent to the Borrower and each Lender.

                 SECTION 10.9.    GOVERNING LAW; ENTIRE AGREEMENT.  (a) THIS
AGREEMENT AND THE NOTES SHALL EACH BE DEEMED TO BE A CONTRACT MADE UNDER AND
GOVERNED BY THE INTERNAL LAWS OF THE STATE OF NEW YORK.  This Agreement, the
Notes and the other Loan Documents constitute the entire understanding among
the parties hereto with respect to the subject matter hereof and supersede any
prior agreements, written or oral, with respect thereto.

                 (b)      EACH PARTY TO THIS AGREEMENT HEREBY IRREVOCABLY
SUBMITS TO THE JURISDICTION OF ANY NEW YORK STATE OR FEDERAL COURT SITTING IN
NEW YORK IN ANY ACTION OR PROCEEDING ARISING OUT OF OR RELATING TO THIS
AGREEMENT OR ANY OTHER LOAN DOCUMENT OR RELATED DOCUMENT, AND EACH HEREBY
IRREVOCABLY AGREES THAT ALL CLAIMS IN RESPECT OF SUCH ACTION OR PROCEEDING MAY
BE HEARD AND DETERMINED IN SUCH NEW YORK STATE OR FEDERAL COURT.  THE BORROWER
AGREES THAT SUCH JURISDICTION SHALL BE EXCLUSIVE WITH RESPECT TO ANY SUCH
ACTION OR PROCEEDING BROUGHT BY IT AGAINST THE AGENT OR ANY LENDER.  EACH PARTY
TO THIS AGREEMENT HEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT IT MAY
EFFECTIVELY DO SO, THE DEFENSE OF ANY INCONVENIENT FORUM TO THE MAINTENANCE OF
SUCH ACTION OR PROCEEDING.

                 (c)      The Borrower hereby irrevocably designates, appoints
and empowers CT Corporation System, whose present address is 1633 Broadway, New
York, New York 10019, as its authorized  agent to receive, for and on its
behalf and its property, service of process in the State of New York when and
as such legal actions or proceedings may be brought in the courts of the State
of New York or of the United States of America sitting in New York, and such
service of process shall be deemed complete upon the date of delivery thereof
to such agent whether or not such agent gives notice thereof to the Borrower,
or upon the earliest of any other date permitted by applicable law.  The
Borrower shall furnish the consent of CT Corporation System so to act to the
Agent on or prior to the Closing Date.  It is understood that a copy of said
process served on such agent will as soon as practicable be forwarded to the
Borrower, at its address set forth below, but its failure to receive such copy
shall not affect in any way the service of said process on said agent as the
agent of the Borrower.  The Borrower irrevocably consents to the service of
process out of any of the aforementioned courts in any such action or
proceeding by the mailing of the copies thereof by certified mail, return
receipt requested, postage prepaid, to it at its address set forth herein, such
service to become effective upon the earlier of (i) the date 10 calendar days
after such mailing or (ii) any earlier date permitted by applicable law.  The
Borrower agrees that it will at all times continuously maintain an agent to
receive service of process in the State of New York on behalf of itself and its
properties and in the event that, for any reason, the agent named above or its
successor shall no longer serve as its agent to receive service of process in
the State of New York on its behalf,





                                       97
<PAGE>   104
it shall promptly appoint a successor so to serve and shall advise the Agent
and the Lenders thereof (and shall furnish to the Agent the consent of any
successor agent so to act).  Nothing in this SECTION 10.9 shall affect the
right of the Agent or any Lender to bring proceedings against the Borrower in
the courts of any other jurisdiction or to serve process in any other manner
permitted by applicable law.

                 SECTION 10.10.   SUCCESSORS AND ASSIGNS.  This Agreement shall
be binding upon and shall inure to the benefit of the parties hereto and their
respective successors and assigns; PROVIDED, HOWEVER, that the Borrower may not
assign or transfer its rights or obligations hereunder without the prior
written consent of all Lenders; and the rights of sale, assignment and transfer
of the Lenders are subject to SECTION 10.11.

                 SECTION 10.11.   SALE AND TRANSFERS, PARTICIPATIONS, ETC.

                 (a)      Any Lender may at any time sell to one or more
Participants participating interests in any Loan owing to such Lender, any Note
held by such Lender, the Revolving Loan Commitment of such Lender, or any other
interest of such Lender hereunder.  In the event of any such sale by a Lender
of participating interests to a Participant, such Lender's obligations under
this Agreement shall remain unchanged and such Lender shall remain solely
responsible for the performance thereof, such Lender shall remain the holder of
any such Note for all purposes under this Agreement and the other Loan
Documents,  and the Borrower and the Agent shall continue to deal solely and
directly with such Lender in connection with such Lender's rights and
obligations under this Agreement and the other Loan Documents.  The Borrower
agrees that if amounts outstanding under this Agreement and the Notes are due
or unpaid, or shall have been declared or shall have become due and payable
upon the occurrence of an Event of Default, each Participant shall be deemed to
have the right of setoff in respect of its participating interest in amounts
owing under this Agreement and any Note to the same extent as if the amount of
its participating interest were owing directly  to it as a Lender under this
Agreement or any Note, PROVIDED that such right of setoff shall be subject to
the approval of the Required Lenders and to the obligations of such Participant
to share with the Lenders, and the Lenders agree to share with such
Participant, as provided in SECTION 3.7 as if the Participant were a Lender
hereunder.  The Borrower also agrees that each Participant shall be entitled to
the benefits of (i) SECTION 10.4 and (ii) SECTIONS 2.4 and 3.6, with respect to
its participation in the Commitments and the Loans outstanding from time to
time; PROVIDED, that no Participant shall be entitled to receive any greater
amount pursuant to the Sections referred to in clause (ii) than the transferor
Lender would have been entitled to receive in respect of the amount of the
participation transferred by such transferor Lender to such Participant had no
such transfer occurred.  No Lender shall grant





                                       98
<PAGE>   105
any participation under which the Participant shall have rights to approve any
amendment to or waiver of this Agreement or any other Loan Document except to
the extent such amendment or waiver would (i) extend the due date for, or
reduce the amount of, any payment or prepayment of principal of or interest on
the Loan or reduce the principal amount of or rate of interest on the Loan
(except in connection with a waiver of interest at the Post-Default Rate) (it
being understood that a waiver of any Default or Event of Default shall not
constitute a change in the terms of such participation, and that an increase in
the Loan shall be permitted without consent of any Participant if the
Participant's participation is not increased as a result thereof), (ii) release
a substantial part of the Collateral, or (iii) consent to the assignment or
transfer by the Borrower of any of its rights and obligations under this
Agreement.

                 (b)      Subject to the provisions of clause (g) of this
SECTION 10.11, with the consent of the Required Lenders and the consent of the
Borrower (which consent, in all instances, shall not be unreasonably withheld
or delayed), any Lender may at any time sell to any Purchasing Lender all or
any part in a minimum amount of $1,000,000, of its rights and obligations under
this Agreement and the Notes pursuant to a Transfer Supplement, executed by
such Purchasing Lender, such transferor Lender, the Agent and the Borrower.
Upon (i) such execution of such Transfer Supplement, and (ii) delivery of a
fully executed copy thereof to the Borrower, such Purchasing Lender shall for
all purpose be a Lender party to this Agreement and shall have all the rights
and obligations of a Lender under this Agreement, to the same extent as if it
were an original party hereto with a Revolving Percentage  and Term Percentage
as set forth in such Transfer Supplement, and no further consent or action by
the Borrower, the Lenders or the Agent shall be required.  Such Transfer
Supplement shall be deemed to amend this Agreement to the extent, and only to
the extent, necessary to reflect the addition of such Purchasing Lender and the
resulting adjustment of Revolving Percentages and Term Percentages arising from
the purchase by such Purchasing Lender of all or a portion of the rights and
obligations of such transferor Lender under this Agreement and the Notes.  Upon
the consummation of any transfer to a Purchasing Lender pursuant to this
paragraph (b), the transferor Lender, the Agent and the Borrower shall make
appropriate arrangements so that, if required, replacement Notes are issued to
such transferor Lender and new Notes to the Purchasing Lender in the amount
equal to their respective Revolving Loan Commitments and outstanding Loans, as
appropriately adjusted pursuant to such Transfer Supplement.

                 (c)      The Agent shall maintain at its address referred to
herein a copy of each Transfer Supplement delivered to it and the Register for
the recordation of the names and addresses of the Lenders and the Revolving
Loan Commitment of, and principal amount of the Loans owing to, each Lender
from time to time.  The entries





                                       99
<PAGE>   106
in the Register shall be conclusive, in the absence of manifest error, and the
Borrower, the Agent and the Lenders may treat each Person whose name is
recorded in the Register as the owner of the Loans recorded therein for all
purposes of this Agreement.  The Register shall be available for inspection by
the Borrower or any Lender at any reasonable time and from time to time upon
reasonable prior notice.

                 (d)      Upon its receipt of a Transfer Supplement executed by
a transferor Lender, the Agent and a Purchasing Lender together with payment by
such Purchasing Lender to the Agent, for the account of the Agent and not for
the account of the Lenders, of a registration and processing fee of $2,500, and
the Notes subject to such Transfer Supplement, the Agent shall (i) accept such
Transfer Supplement, (ii) record the information therein in the Register and
(iii) give prompt notice of such acceptance and recordation to the Lenders and
the Borrower.

                 (e)      If, pursuant to this SECTION 10.11, any interest in
this Agreement or any Note is transferred to any Participant or Purchasing
Lender which is organized under the laws of any jurisdiction other than the
United States or any State thereof, the transferor Lender shall cause such
Participant or Purchasing Lender, concurrently with the effectiveness of such
transfer, (i) to represent to the transferor Lender (for the benefit of the
transferor Lender, the Agent and the Borrower) that under applicable law and
treaties no taxes will be required to be withheld by the Agent, the Borrower or
the transferor Lender with respect to any payments to be made to such
Participant or Purchasing Lender in respect of the Loans or Commitments, (ii)
to furnish to the transferor Lender, the Agent and the Borrower two properly
executed original Internal Revenue Service Forms 4224 or  1001 (or any
successor forms) and properly executed Internal Revenue Service Forms W-8 and
W-9, as the case may be, (wherein such Participant or Purchasing Lender claims
entitlement to complete exemption from the United States federal withholding
tax on all interest payments hereunder and all fees payable under SECTION 2.3)
and (iii) to agree (for the benefit of the transferor Lender, the Agent and the
Borrower) to provide the transferor Lender, the Agent and the Borrower new
Internal Revenue Service Forms 4224 or 1001 upon the expiration or obsolescence
of any previously delivered form or after the occurrence of any event requiring
a change in the most recent forms delivered by it to the Transferor Lender, the
Agent and the Borrower, and comparable statements in accordance with applicable
United States laws and regulations and amendments duly executed and completed
by such Participant or Purchasing Lender, and to comply from time to time with
all applicable United States laws and regulations with regard to such
withholding tax exemption.

                 (f)      Notwithstanding anything to the contrary set forth in
this SECTION 10.11, but subject to the provisions of clause (g)





                                      100
<PAGE>   107
of this SECTION 10.11, (i) any Lender may sell to any of its Affiliates all or
any part of its rights and obligations under this Agreement and the Notes, (ii)
any Lender may create a security interest in all or any portion of its rights
under this Agreement (including, without limitation, the Loans owing to it and
the Notes held by it) in favor of the Federal Reserve Bank in accordance with
Regulation A of the F.R.S.  Board, and (iii) upon the occurrence and during the
continuance of an Event of Default, any Lender may sell to any Purchasing
Lender all or any part of its rights and obligations under this Agreement and
the Notes, in the case of clause (i) or (iii) above, notwithstanding that the
Borrower does not consent to such sale, provided such Lender has obtained the
consent of the Agent (which consent shall not be unreasonably withheld or
delayed) and otherwise meets the requirements of this SECTION 10.11.  The Agent
agrees to waive the registration and processing fee set forth in clause (d) of
this SECTION 10.11 in connection with the exercise by any Lender of its rights
under clause (i) of the preceding sentence prior to April 15, 1996.

                 (g)      If any transfer of a Term Note is not made pursuant
to an effective registration statement under the Securities Act, the Lender
desiring to transfer such Term Note will, if reasonably requested by the
Borrower, deliver to the Borrower an opinion of counsel, which may be counsel
to such Lender but which counsel must be reasonably satisfactory to the
Borrower (provided that King & Spalding and Lowenstein, Sandler, Kohl, Fisher &
Boylan shall be deemed reasonably satisfactory), reasonably satisfactory in
form, scope and substance to the Borrower, that such Term Note may be sold
without registration under the Securities Act, and the Purchasing Lender shall
upon purchase of such Term Note or portion thereof be deemed to have affirmed
and agreed to the investment representation set forth in SECTION 2.5.  Each
Lender agrees that its Term Note will bear the following legend:


                           "THIS TERM NOTE HAS NOT BEEN REGISTERED UNDER THE
                           SECURITIES ACT OF 1933, AS AMENDED, OR ANY STATE
                           SECURITIES LAWS, AND MAY NOT BE SOLD OR TRANSFERRED
                           IN THE ABSENCE OF SUCH REGISTRATION OR AN EXEMPTION,
                           OR AN OPINION OF COUNSEL (WHICH MAY BE COUNSEL TO
                           THE HOLDER) AS TO AN EXEMPTION, FROM THE
                           REGISTRATION PROVISIONS OF SAID ACT OR LAWS."

Each Lender further agrees that its Term Note will bear the following legend:

                          "THIS TERM NOTE IS SUBJECT TO THE TERMS OF A CREDIT
                          AGREEMENT, DATED AS OF MARCH 15, 1996, BETWEEN

                          CAPITAL CORPORATION, AS AGENT FOR THE LENDERS, COPIES
                          OF EACH OF WHICH ARE ON FILE AT THE MAIN OFFICE OF
                          THE BORROWER.  ANY SALE OR TRANSFER OF THE SECURITIES
                          EVIDENCED BY THIS TERM NOTE IS SUBJECT TO THE TERMS
                          OF SAID CREDIT AGREEMENT AND ANY SALE OR TRANSFER OF
                          SUCH SECURITIES IN VIOLATION OF SAID CREDIT AGREEMENT
                          SHALL BE INVALID."

                 (h)      If any transfer of any shares of Series B Special
Preferred Stock or Common Stock issued upon conversion of Series B Special
Preferred Stock (any such shares, "TERM NOTE SHARES") is not made pursuant to
an effective registration statement under the Securities Act, the holder
desiring to transfer such Term Note Shares will, if reasonably requested by the
Borrower, deliver to the Borrower an opinion of counsel, which may be counsel
to such holder but which counsel must be reasonably satisfactory to the
Borrower (provided that King & Spalding and Lowenstein, Sandler, Kohl, Fisher &
Boylan shall be deemed reasonably satisfactory), reasonably satisfactory in
form, scope and substance to the Borrower, that such Term Note Shares may be
sold without registration under the Securities Act, as well as (i) an
investment covenant reasonably satisfactory to the Borrower signed by the
proposed transferee (except that no such covenant will be required in
connection with a transfer effected in accordance with Rule 144A under the
Securities Act), and (ii) an agreement by such transferee to the impression of
the restrictive legends set forth below on the Term Note Shares.

All Term Note Shares will bear the following legend (the "SECURITIES LEGEND"):

                          "THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE
                          NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933,
                          AS AMENDED, OR ANY STATE SECURITIES LAWS, SAID
                          SECURITIES MAY NOT BE SOLD OR TRANSFERRED IN THE
                          ABSENCE OF SUCH REGISTRATION OR AN EXEMPTION, OR AN
                          OPINION OF COUNSEL (WHICH MAY BE COUNSEL TO THE
                          HOLDER) AS TO AN EXEMPTION, FROM THE REGISTRATION
                          PROVISIONS OF SAID ACT OR LAWS."

Notwithstanding the foregoing provisions of this clause (h) of SECTION 10.11,
the restrictions upon the transferability of Term Note Shares and the
Securities Legend requirements set forth in this clause (h) of this SECTION
10.11 shall terminate as to any such Term Note Shares (i) when and so long as
such Term Note Shares shall have been effectively registered under the
Securities Act and





                                      102
<PAGE>   109
disposed of pursuant thereto or (ii) when the Borrower shall have received an
opinion of counsel reasonably satisfactory to it that such Securities Legend is
not required in order to ensure compliance with the Securities Act.  Whenever
the restrictions imposed by this clause (h) of  SECTION 10.11 shall terminate
as to any Term Note Shares as hereinabove provided, the holder thereof shall be
entitled to receive from the Borrower, at the expense of the Borrower, a new
certificate or certificates for such Term Note Shares bearing the following
legend in place of the Securities Legend set forth above:

                          "THE RESTRICTIONS ON TRANSFERABILITY OF THE
                          SECURITIES REPRESENTED BY THIS CERTIFICATE TERMINATED
                          ON ______________, 19__, AND ARE OF NO FURTHER FORCE
                          AND EFFECT."

In addition, each certificate representing Term Note Shares will bear the
following legend:

                          "THE SECURITIES REPRESENTED BY THIS CERTIFICATE ARE
                          SUBJECT TO THE TERMS OF CLAUSE (H) OF SECTION 10.11
                          OF A CREDIT AGREEMENT, DATED AS OF MARCH 15, 1996,
                          BETWEEN PHONETEL TECHNOLOGIES, INC. (THE "COMPANY"),
                          THE LENDERS NAMED THEREIN, AND INTERNATIONALE
                          NEDERLANDEN (U.S.) CAPITAL CORPORATION ("ING") AS
                          AGENT FOR THE LENDERS, COPIES OF EACH OF WHICH ARE ON
                          FILE AT THE MAIN OFFICE OF THE COMPANY.  ANY SALE OR
                          TRANSFER OF THE SECURITIES EVIDENCED BY THIS
                          CERTIFICATE IS SUBJECT TO THE TERMS OF SAID AGREEMENT
                          AND ANY SALE OR TRANSFER OF SUCH SECURITIES IN
                          VIOLATION OF SAID AGREEMENT SHALL BE INVALID."


                 SECTION 10.12.   OTHER TRANSACTIONS.  Nothing contained herein
shall preclude the Agent or any other Lender from engaging in any transaction,
in addition to those contemplated by this Agreement or any other Loan Document,
with the Borrower or any of its Affiliates in which the Borrower or such
Affiliate is not restricted hereby from engaging with any other Person.

                 SECTION 10.13.   CONFIDENTIALITY.  (a)  The Lenders and the
Agent shall treat any information concerning the Borrower (whether prepared by
the Borrower, its advisors or otherwise) which has been or will be furnished by
or on behalf of the Borrower or any Subsidiary thereof (herein collectively
referred to as the "CONFIDENTIAL INFORMATION") in accordance with the customary
procedures for handling confidential information of this nature and





                                      103
<PAGE>   110
will not willfully disclose any Confidential Information to any other party,
except as otherwise provided herein.  The Confidential Information will be used
solely in connection with the transactions contemplated by the Loan Documents
or as otherwise authorized by the Borrower.  The term "Confidential
Information" does not include information which (i) is or becomes generally
available to the public other than as a result of a disclosure by the Agent,
the Lenders or their respective affiliates, directors, officers or employees,
or (ii) becomes available on a nonconfidential basis from a source other than
the Borrower, any of its Subsidiaries, or their advisors, provided that such
source is not known by the Agent or the Lenders to be bound by a
confidentiality agreement with or other obligation of secrecy to the Borrower
or any of its Subsidiaries.

                 (b)      Notwithstanding the foregoing, (i) Confidential
Information may be disclosed to the Agent's and Lenders' affiliates, directors,
partners, officers, employees and advisors who are in a confidential
relationship with such Person or who are informed of the confidential nature of
such information, (ii) Confidential Information may be disclosed as reasonably
required by any proposed syndicate member or any proposed transferee or
participant in connection with the contemplated transfer of any Note or
participation therein or of any Loan Document or related document, PROVIDED
that any such proposed syndicate member or proposed transferee or participant
shall have agreed in writing for the Borrower's benefit to be bound by the
terms of this SECTION 10.13, and shall agree to return any Confidential
Information, and will not retain any copies, extracts or other reproductions in
whole or in part of such Confidential Information, if it does not become a
syndicate member, transferee or participant, (iii) Confidential Information may
be disclosed to the extent requested or required by bank regulators or auditors
or any administrative body or commission to whose jurisdiction the Agent or a
Lender may be subject, (iv) Confidential Information may be disclosed to the
extent required by law, regulation, subpoena, judicial order or legal process,
provided that notice of such requirement or order shall be promptly furnished
to the Borrower unless such notice is legally prohibited, (v) Confidential
Information may be disclosed to the extent  required by the rules of any
securities exchange on which securities of the Agent or any Lender are listed
and traded, (vi) Confidential Information may be disclosed in connection with
the enforcement by the Agent or any Lender of its rights under the Loan
Documents or in connection with any litigation between any Loan Party and the
Agent or any Lender with respect to the Loan or any Loan Document, and (vii)

to such disclosure.

                 SECTION 10.14.   CHANGE IN ACCOUNTING PRINCIPLES.  If

                 (a)      any changes in accounting principles from those used
in the preparation of the financial statements referred to in





                                      104
<PAGE>   111
clause (a)(i) of SECTION 5.4 hereafter occur as a result of the promulgation of
rules, regulations, pronouncements or opinions by the Financial Accounting
Standards Board or the American Institute of Certified Public Accountants (or
successors thereto or agencies with similar functions) result in a change in
the method of calculation of financial covenants, standards or terms found in
this Agreement; or

                 (b)      there is any change in the Borrower's Fiscal Year
with the Required Lenders' prior written consent pursuant to SECTION 6.2.16
hereof;

the parties hereto agree to enter into negotiations in order to amend such
financial covenants, standards or terms so as to equitably reflect such changes
with the desired result that the evaluations of the Borrower's financial
condition shall be the same after such changes as if such changes had not been
made; PROVIDED, HOWEVER, that, until the parties hereto have reached a
definitive agreement on such amendments the Borrower shall not change its
Fiscal Year and the Borrower's financial condition and operations shall
continue to be evaluated on the same principles as those used in the
preparation of the financial statements referred to in clause (a)(i) of SECTION
5.4.

                 SECTION 10.15.   WAIVER OF JURY TRIAL, ETC.  THE AGENT, THE
LENDERS AND THE BORROWER HEREBY KNOWINGLY, VOLUNTARILY, AND INTENTIONALLY WAIVE
ANY RIGHTS THEY MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION BASED
HEREON, OR ARISING OUT OF, UNDER, OR IN CONNECTION WITH, THIS AGREEMENT, THE
NOTES OR ANY OTHER LOAN DOCUMENT, OR ANY COURSE OF CONDUCT, COURSE OF DEALING,
STATEMENTS (WHETHER VERBAL OR WRITTEN), OR ACTIONS OF THE AGENT, SUCH LENDERS,
OR THE BORROWER.  THIS PROVISION IS A MATERIAL INDUCEMENT FOR THE AGENT AND
SUCH LENDERS ENTERING INTO THIS AGREEMENT.

                 SECTION 10.16.   LIMITATION OF LIABILITY.  Neither the Agent,
the Lenders nor any Affiliate thereof shall have any liability with respect to,
and THE BORROWER HEREBY WAIVES, RELEASES AND AGREES NOT TO SUE UPON, ANY CLAIM
FOR ANY SPECIAL, INDIRECT, PUNITIVE, EXEMPLARY OR CONSEQUENTIAL DAMAGES
SUFFERED BY THE BORROWER IN CONNECTION WITH, ARISING OUT OF, OR IN ANY WAY
RELATED TO THIS AGREEMENT, THE LOAN DOCUMENTS, THE TRANSACTIONS  CONTEMPLATED
HEREIN, OR ANY ACT, OMISSION OR EVENT OCCURRING IN CONNECTION THEREWITH.

                 SECTION 10.17.   USURY SAVINGS CLAUSE.  Notwithstanding
anything to the contrary in this Agreement or any other Loan Document, if at
any time any rate of interest accruing on any Obligation, when aggregated with
all amounts payable by the Borrower or any other Loan Party under any of the
Loan Documents that are deemed or construed to be interest accrued or accruing
on such Obligation under applicable law, exceeds the highest rate of interest
permissible under any law which a court of competent





                                      105
<PAGE>   112
jurisdiction shall, in a final determination, deem applicable to such Lender
with respect to such Obligation (each a "MAXIMUM LAWFUL RATE"), then in such
event and so long as the Maximum Lawful Rate would be so exceeded, such rate of
interest shall be reduced to the Maximum Lawful Rate; PROVIDED that if at any
time thereafter such rate of interest accruing on Obligations held by such
Lender is less than the Maximum Lawful Rate, the Borrower shall continue to pay
interest to such Lender at the Maximum Lawful Rate until such time as the total
interest received by such Lender in respect of the Obligations held by it is
equal to the total interest which such Lender would have received had interest
on all Obligations held by such Lender (but for the operation of this SECTION
10.17) accrued at the rate otherwise applicable under this Agreement and the
other Loan Documents.  Thereafter, interest payable to such Lender in respect
of the Obligations held by it shall accrue at the applicable rate set forth in
this Agreement or other Loan Documents unless and until such rate again exceeds
the Maximum Lawful Rate, in which event this SECTION 10.17 shall again apply.
In no event, shall the total interest received by any Lender pursuant to the
terms hereof exceed the amount which such Lender could lawfully have received
had interest been calculated for the full term of this Agreement at the Maximum
Lawful Rate.  In the event that the Maximum Lawful Rate is calculated pursuant
to this SECTION 10.17, (a) if required by applicable law, such interest shall
be calculated at a daily rate equal to the Maximum Lawful Rate divided by the
number of days in the year in which such calculation is made, and (b) if
permitted by applicable law, the Borrower and such Lender shall (i)
characterize any non-principal payment as an expense, fee or premium rather
than as interest, (ii) exclude voluntary prepayments and the effect thereof,
and (iii) amortize, prorate, allocate and spread in equal or unequal parts the
total amount of interest throughout the entire contemplated term of the Loans
so that interest for the entire term of the Loans shall not exceed the Maximum
Lawful Rate.  In the event that a court of competent jurisdiction,
notwithstanding the provisions of this SECTION 10.17 shall make a final
determination that any Lender has received interest in excess of the Maximum
Lawful Rate, such Lender shall, to the extent permitted by applicable law,
promptly apply such excess, FIRST to any interest due and outstanding under
this Agreement and the other Loan Documents, SECOND to any principal due and
payable under this Agreement and the Notes, THIRD to the remaining principal
amount of the Notes and FOURTH to other unpaid  Obligations held by such
Lender, and thereafter shall refund any excess to the Borrower or as a court of
competent jurisdiction may otherwise order.

                 SECTION 10.18.   CONFLICT IN LOAN DOCUMENTS.  To the extent
there is any actual irreconcilable conflict between the provisions of this
Agreement and any other Loan Document, the provisions of this Agreement shall
prevail.

                            CASH MANAGEMENT SYSTEM
_______________________________________________________________________________

         The Borrower agrees to establish on or prior to April 15, 1996 (the
"EFFECTIVE DATE"), and to thereafter maintain at all times, the cash management
system described below:

         1.      Neither the Borrower nor any of its Subsidiaries shall
maintain any deposit, checking, operating or other bank account except for the
Coin Concentration Account and the Receivables Concentration Account described
below, and those accounts of the Borrower and its Subsidiaries identified below
in paragraph 12.  The Borrower shall not permit the aggregate Net Balances in
its Disbursement Account and any other deposit account of the Borrower and its
Subsidiaries (other than the Blocked Accounts and Concentration Accounts), to
exceed on any Business Day $150,000.  If as of the close of any Business Day
such Net Balances so exceed $150,000, the Borrower shall make a mandatory
prepayment of the Revolving A Loans and the Revolving B Loans on such Business
Day in the amount of such excess.  As used herein "NET BALANCE" means the
amount of collected funds in an account less the amount of all unpaid checks,
drafts and other items drawn on such account.

         2.      Commencing on the Effective Date, the Borrower and its
Subsidiaries shall deposit or cause to be deposited, on the date of receipt
thereof, all cash collected from Telephones into one or more accounts
identified below in paragraph 12 as "Blocked Accounts" (collectively, the
"BLOCKED ACCOUNTS").

         3.      On or before the Effective Date, the Borrower shall have
established a concentration account in the Borrower's name (the "COIN
CONCENTRATION ACCOUNT") and a second concentration account in the Borrower's
name (the "RECEIVABLES CONCENTRATION ACCOUNT"), each at a bank reasonably
acceptable to the Required Lenders.  The Coin Concentration Account and the
Receivables Concentration Account are collectively referred to as the
"Concentration Accounts".

         4.      On or before the Effective Date, each of the Borrower shall
have delivered to each account debtor with respect to its accounts receivables
an irrevocable notice and direction to mail all payments in respect of accounts
receivable to a lockbox established with the bank at which the Receivables
Concentration Account is established, which payments are to be deposited
directly by such bank into the Receivables Concentration Account in accordance
with the terms of the Receivables Concentration Account Agreement described
below.  In the event that, notwithstanding the irrevocable notices and
directions given by the Borrower and its Subsidiaries to account debtors, the
Borrower or any its Subsidiaries receives any check or other item of payment
with respect to its accounts receivable the Borrower or such Subsidiary shall
hold such items in trust for the benefit of  the Agent and deposit the same on
the date of receipt thereof in the Receivables Concentration Account.

<PAGE>   119
         5.      On or before the Effective Date, the banks at which the
Blocked Accounts are maintained shall have entered into tri-party blocked
account agreements (the "BLOCKED ACCOUNT AGREEMENTS") with the Agent, the
Borrower and any other depositor, in form and substance reasonably satisfactory
to the Required Lenders.  Each such Blocked Account Agreement shall provide,
among other things, that (a) such bank executing such agreement has no rights
of set-off or recoupment or any other claim against such Blocked Account, other
than for payment of its service fees and other charges directly related to the
administration of such account, (b) such bank agrees to sweep on a daily basis
all amounts received in the Blocked Account to the Coin Concentration Account
and (c) the Agent has exclusive dominion and control of, and a first priority
security interest in, such Blocked Account.

         6.      On or before the Effective Date, the bank at which the Coin
Concentration Account is maintained shall have entered into a tri-party
concentration account agreement (the "COIN CONCENTRATION ACCOUNT AGREEMENT")
with the Agent and the Borrower, in form and substance reasonably satisfactory
to the Required Lenders.  Such Coin Concentration Account Agreement shall
provide, among other things, that (a) such bank executing such agreement has no
rights of set-off or recoupment or any other claim against such Coin
Concentration Account, other than for payment of its service fees and other
charges directly related to the administration of such account, (b) such bank
agrees to sweep on a daily basis all amounts received in the Coin Concentration
Account to the Collection Account and (c) the Agent has exclusive dominion and
control of, and a first priority security interest in, the Coin Concentration
Account.

         7.      On or before the Effective Date, the bank at which the
Receivables Concentration Account is maintained, shall have entered into a
tri-party concentration account agreement (the "RECEIVABLES CONCENTRATION
ACCOUNT AGREEMENT") with the Agent and the Borrower, in form and substance
reasonably satisfactory to the Required Lenders.  Such Receivables Accounts
Concentration Account Agreement shall provide, among other things, that (a)
such bank executing such agreement has no rights of set-off or recoupment or
any other claim against such Receivables Concentration Account, other than for
the payment of its service fees and other charges directly related to the
administration of such account, (b) such bank shall deposit all receipts from a
lockbox to be established with such bank into the Receivables Concentration
Account, (c) such bank agrees to sweep on a daily basis all amounts received in
the Receivables Concentration Account to the Collection Account, and (d) the
Agent has exclusive dominion and control of, and a first priority security
interest in, the Receivables Concentration Account.

         8.      The Borrower may maintain, in its name, an account (the
"DISBURSEMENT ACCOUNT") at a bank reasonably acceptable to the Required Lenders
into which the Agent shall, from time to time, deposit proceeds of Revolving A
Loans or Revolving B Loans made pursuant to SECTION 2.1.1 or SECTION 2.1.2 for
use solely in accordance with the provisions of SECTION 3.9.  The Disbursement
Account as of the Closing Date is identified below in paragraph 12

as the "Disbursement Account".

         9.      All amounts deposited in the Collection Account shall be
deemed received by the Agent in accordance with the terms of SECTION 3.6.  In
no event shall any amount be so applied unless and until such amount shall have
been credited in immediately available funds to the Collection Account.

         10.     The Borrower hereby constitutes and irrevocably appoints, from
and after the Closing Date until payment in full of all Loans and the
termination of the Commitments, the Agent as its true and lawful attorney, with
full power of substitution, to demand, collect, receive and sue for all amounts
which may become due and payable under the Blocked Accounts, Coin Concentration
Account, and the Receivables Concentration Account, and to exercise all
withdrawal receipts or other orders for the Borrower or any of its Subsidiaries
in the Agent's own name or in the Borrower's or its Subsidiary's name or
otherwise, which the Agent deems necessary or appropriate to protect and
preserve its right, title and interest in such accounts.

         11.     Upon the request of the Required Lenders, the Borrower shall
forward to the Lenders, on a daily basis, evidence of the deposit of all items
of payment received by the Borrower into the Blocked Accounts, the Coin
Concentration Account and the Receivables Concentration Agreement, and copies
of all such checks and other items, in form and substance reasonably
satisfactory to the Required Lenders.

         12.     The following consists of all of the deposit, checking,
operating and other bank accounts of the Borrower and its Subsidiaries as of
the Closing Date.

         Inventory to a purchaser in the ordinary course of business) or any of
         such Grantor's agents or processors, such Grantor shall notify in
         writing such warehouseman, bailee, agent or processor of the Security
         Interests created hereby, shall obtain such warehouseman's, bailee's,
         agent's or processor's agreement in writing to hold all such

         exchange, assign or otherwise dispose of, or grant any option, warrant

         the rights of the Agent and the Lenders hereunder if an Event
         of Default shall have occurred and be continuing, the Grantors may

         of the Credit Agreement, whereupon, in the case of such a disposition,
         sale or exchange, the Security Interests created hereby  in such item

         exchange) shall cease immediately without any further action on the
         part of the Agent; or (B) create, incur or suffer to exist any Lien

                             (ii) Upon the occurrence and during the 
         continuance of any Event of Default, upon request of the Agent,
         each Grantor will promptly notify (and each Grantor hereby authorizes
         the Agent so to notify) each Account Debtor in respect of any Account
         or Instrument that such Collateral has been assigned to the Agent
         hereunder, and that any payments due or to become due in respect of
         such Collateral are to be made directly to the Agent or its designee.

                            (iii) Each Grantor will perform and comply in all
         material respects with all of its obligations in respect of Accounts,
         Instruments and General Intangibles.

         the Agent immediately of any additional location where Inventory is

as lienholder on any such certificate of title and applications.  The Grantors
shall promptly inform the Agent of any material additions to or deletions from
the Equipment and shall not permit any such items to become a fixture to real
estate or an accession to other personal property.

                 (e)      PATENTS, TRADEMARKS, ETC.  The Grantors shall notify
the Agent immediately (i) of its acquisition after the Closing Date of any
patent, patent license, Trademark or Trademark License and (ii) if it knows, or
has reason to know, that any application or registration relating to any patent
or Trademark owned by or licensed to the Grantors is reasonably likely to
become abandoned or dedicated, or of any adverse determination or development
(including, without limitation, the institution of, or any such determination
or development in, any proceeding in the United States Patent and Trademark
Office or any court) regarding any Grantor's ownership of any patent or
Trademark, its right to register the same, or to keep and maintain the same.
In the event that any patent, patent license, Trademark or Trademark License is
infringed, misappropriated or diluted by a third party, the Grantors shall
notify the Agent promptly after they learn thereof and shall, unless the
Grantors shall reasonably determine that any such action would be of immaterial
economic value, promptly sue for infringement, misappropriation or dilution and
to recover any and all damages for such infringement, misappropriation or
dilution, and take such other actions as the Grantors shall reasonably deem
appropriate under the circumstances to protect such patent, patent





                                       11

license, Trademark or Trademark License.  In no event shall the Grantors,
either themselves or through any agent, employee or licensee, file an
application for the registration of any patent or Trademark with the United
States Patent and Trademark Office or any similar office or agency in any other
country or any political subdivision thereof, unless not less than thirty (30)
days prior thereto it informs the Agent, and, upon issuance of such patent or
Trademark, executes and delivers any and all agreements, instruments, documents
and papers the Agent may reasonably request to evidence the Security Interests
in such patent or Trademark and the goodwill and general intangibles of the
Grantors relating thereto or represented thereby.  Each Grantor hereby
constitutes the Agent its attorney-in-fact to execute and file all such
writings for the foregoing purposes, all acts of such attorney being hereby
ratified and confirmed, and such power, being coupled with  an interest, shall
be irrevocable until the Commitments have terminated and the Secured
Obligations are paid in full.

         SECTION 5.  REPORTING AND RECORDKEEPING.  Each Grantor covenants and
agrees with the Agent and the Lenders that from and after the date of this
Agreement and until the Commitments have terminated, and all Secured
Obligations are paid in full.

                 (a)      MAINTENANCE OF RECORDS GENERALLY.  Such Grantor will
keep and maintain at its own cost and expense records of the Collateral,
complete in all material respects, including, without limitation, a record of
all payments received and all credits granted with respect to the Collateral
and all other dealings with the Collateral.  Such Grantor will mark its books
and records pertaining to the Collateral to evidence this Agreement and the
Security Interests.  All Chattel Paper will be marked with the following
legend:  "This writing and the obligations evidenced or secured hereby are
subject to the security interest of Internationale Nederlanden (U.S.) Capital
Corporation, as Agent".  For the Agent's and the Lenders' further security,
such Grantor agrees that the Agent and the Lenders shall have a security
interest in all of the Grantor's books and records pertaining to the Collateral
and, upon the occurrence and during the continuation of any Default or Event of
Default, the Grantor shall deliver and turn over full and complete copies of
any such books and records to the Agent or to its representatives at any time
on demand of the Agent.  Prior to the occurrence of a Default or an Event of
Default and upon reasonable notice from the Agent, such Grantor shall permit
any representative of the Agent, at reasonable times and reasonable intervals
upon one Business Day's notice, to inspect such books and records and will
provide photocopies thereof to the Agent.

                 (b)      SPECIAL PROVISIONS REGARDING MAINTENANCE OF RECORDS
AND REPORTING RE: ACCOUNTS, INVENTORY AND EQUIPMENT.

                          (i)  Such Grantor shall keep complete and accurate 
         records of its Accounts. Upon the request of the





                                       12
<PAGE>   13
         Agent, such Grantor shall deliver to the Agent all documents,
         including, without limitation, repayment histories, present status
         reports, relating to the Accounts so scheduled and such other matters
         and information relating to the status of then existing Accounts as
         the Agent shall reasonably request.

                             (ii) In the event any amounts due and owing in
         excess of $50,000 individually or $100,000 in the aggregate are in
         dispute between any Account Debtor and such Grantor, such Grantor
         shall provide the Agent with written notice thereof promptly after
         such Grantor's learning thereof explaining in detail the reason for
         the dispute, all claims related thereto and the amount in controversy.

                             (iii)         Such Grantor shall maintain itemized
         records, accurate in all material respects, itemizing and describing
         the kind, type, quality, quantity, location and book value of its
         Inventory and Equipment and shall furnish the Agent with a current
         schedule containing the foregoing information and upon request by the
         Required Lenders.

                              (iv)         Such Grantor will promptly upon, but
         in no event later than five (5) Business Days after:

                             (A)  Such Grantor's learning thereof, inform the
                 Agent, in writing, of any material delay in the Grantor's
                 performance of any of its material obligations to any Account
                 Debtor and of any assertion of any material claims, offsets or
                 counterclaims by any Account Debtor and of any allowances,
                 credits and/or other monies granted by such Grantor to any
                 Account Debtor, in each case involving amounts in excess of
                 $50,000 for any single Account or Account Debtor or in excess
                 of $100,000 in the aggregate for all Accounts and Account
                 Debtors; and

                             (B)  such Grantor's receipt or learning thereof,
                 furnish to and inform the Agent of all material adverse
                 information relating to the financial condition of any Account
                 Debtor with respect to Accounts exceeding $50,000 individually
                 or $100,000 in the aggregate.

                             (iv) Such Grantor will promptly notify the Agent
         in writing if any Account, the face value of which exceeds $10,000,
         arises out of a contract with the United States of America, or any
         department, agency, subdivision or instrumentality thereof, or of any
         state (or department, agency, subdivision or instrumentality thereof)
         where such state has a state assignment of claims act or other law
         comparable to the Federal Assignment of Claims Act, and will take any
         action required or requested by the Agent to give notice of the
         Agent's security interest in such Accounts under





                                       13
<PAGE>   14
         the provisions of the Federal Assignment of Claims Act or any
         comparable law or act enacted by any state or local governmental
         authority; and

                             (v)  Such Grantor at its expense will cause
         independent public accountants reasonably satisfactory to the Agent to
         prepare and deliver to the Agent at any time and from time to time
         promptly upon the Agent's reasonable request, the following reports:
         (A) a reconciliation of all of its Accounts, (B) an aging of all of
         its Accounts, (C) trial balances, and (D) a test verification of such
         Accounts.

                 (c)      FURTHER IDENTIFICATION OF COLLATERAL.  Such Grantor
will if so requested by the Agent furnish to the Agent, as often as the Agent
reasonably requests, statements and schedules further identifying and
describing the Collateral and such other reports  in connection with the
Collateral as the Agent may reasonably request, all in reasonable detail.

                 (d)      NOTICES.  In addition to the notices required by
SECTION 5(B) hereof, such Grantor will advise the Agent promptly, in reasonable
detail, (i) of any material Lien or claim made or asserted against any of the
Collateral, (ii) of any material adverse change in the composition of the
Collateral, and (iii) of the occurrence of any other event which would have a
material adverse effect on the aggregate value of the Collateral or on the
validity, perfection or priority of the Security Interests.

         SECTION 6.  COLLATERAL ACCOUNTS.  In accordance with the terms of the
Credit Agreement, on or prior to April 15, 1996, each Grantor shall maintain
and abide by the cash management system described in Schedule 3 of the Credit
Agreement.

         SECTION 7.  GENERAL AUTHORITY.  Each Grantor hereby irrevocably
appoints the Agent its true and lawful attorney, with full power of
substitution, in the name of such Grantor, the Agent, the Lenders or otherwise,
for the sole use and benefit of the Agent and the Lenders, but at such
Grantor's expense, to exercise, at any time from time to time all or any of the
following powers:

                             (i)  to file the financing statements, financing
         statement amendments and continuation statements referred to in
         SECTION 4(A)(III),

                             (ii) to demand, sue for, collect, receive and give
         acquittance for any and all monies due or to become due with respect
         to any Collateral or by virtue thereof,

                             (iii)         to settle, compromise, compound,
         prosecute or defend any action or proceeding with respect to any
         Collateral,





                                       14
<PAGE>   15
                             (iv) to sell, transfer, assign or otherwise deal
         in or with the Collateral or the proceeds or avails thereof, as fully
         and effectually as if the Agent were the absolute owner thereof, and

                             (v)  to extend the time of payment of any or all
         thereof and to make any allowance and other adjustments with reference
         to the Collateral;

PROVIDED that the Agent shall not take any of the actions described in this
SECTION 7 except those described in clause (i) above unless an Event of Default
shall have occurred and be continuing.

         SECTION 8.  REMEDIES UPON EVENT OF DEFAULT.

                 (a)      If any Event of Default has occurred and is
continuing, the Agent may exercise on behalf of the Lenders without further
notice, all rights and remedies under this Agreement, the Credit Agreement, the
Subsidiary Guaranty, any other Loan Document or that are available to a secured
creditor under the UCC or that are otherwise available at law or in equity, at
any time, in any order and in any combination, including the following (i) to
collect any and all Obligations from Borrower, (ii) to collect any and all
Guaranteed Obligations from any Subsidiaries under the Subsidiary Guaranty;
and, in addition, the Agent may (i) withdraw all cash, if any, in the
Collateral Account and investments made with amounts on deposit in the
Collateral Account, and apply such monies, investments and other cash, if any,
then held by it as Collateral as specified in SECTION 10 and (ii) sell the
Collateral or any part thereof at public or private sale, for cash, upon credit
or for future delivery, and at such price or prices as the Agent may deem
satisfactory.  The Agent shall give each Grantor not less than ten days' prior
written notice of the time and place of any sale or other intended disposition
of such Grantor's Collateral, except any Collateral which is perishable or
threatens to decline speedily in value or is of a type customarily sold on a
recognized market.  The Grantors agree that any such notice constitutes
"reasonable notification" within the meaning of Section 9-504(3) of the UCC (to
the extent such Section is applicable).

The Agent or any Lender may be the purchaser of any or all of the Collateral so
sold at any public sale (or, if the Collateral is of a type customarily sold in
a recognized market or is of a type which is the subject of widely distributed
standard price quotations or if otherwise permitted under applicable law, at
any private sale) and thereafter hold the same, absolutely, free from any right
or claim of whatsoever kind.  The Grantors will execute and deliver such
documents and take such other action as the Agent deems necessary or advisable
in order that any such sale may be made in compliance with law.  Upon any such
sale the Agent shall have the right to deliver, assign and transfer to the
purchaser





                                       15
<PAGE>   16
thereof the Collateral so sold.  Each purchaser at any such sale shall hold the
Collateral so sold to it absolutely, free from any claim or right of any kind,
including any equity or right of redemption of the Grantors.  To the extent
permitted by law, each Grantor hereby specifically waives all rights of
redemption, stay or appraisal which it has or may have under any law now
existing or hereafter adopted.  The notice (if any) of such sale shall (1) in
case of a public sale, state the time and place fixed for such sale, and (2) in
the case of a private sale, state the day after which such sale may be
consummated.  Any such public sale shall be held at such time or times within
ordinary business hours and at such place or places as the Agent may fix in the
notice of such sale.  At any such sale the Collateral may be sold in one lot as
an entirety or in separate parcels, as the Agent may determine.  The Agent
shall not be obligated to make any such sale pursuant to any such notice.  The
Agent may, without notice or publication, adjourn any public or private sale or
cause the same to be  adjourned from time to time by announcement at the time
and place fixed for the sale, and such sale may be made at any time or place to
which the same may be so adjourned.  In case of any sale of all  or any part of
the Collateral on credit or for future delivery, the Collateral so sold may be
retained by the Agent until the selling price is paid by the purchaser thereof,
but the Agent shall not incur any liability in case of the failure of such
purchaser to take up and pay for the Collateral so sold and, in case of any
such failure, such Collateral may again be sold upon like notice.  The Agent,
instead of exercising the power of sale herein conferred upon it, may proceed
by a suit or suits at law or in equity to foreclose the Security Interests and
sell the Collateral, or any portion thereof, under a judgment or decree of a
court or courts of competent jurisdiction.  The Grantors shall remain liable,
jointly and severally, for any deficiency.

                 (b)      For the purpose of enforcing any and all rights and
remedies under this Agreement, the Agent may (i) require the Grantors to, and
the Grantors agree that they will, at their expense and upon the request of the
Agent, forthwith assemble all or any part of the Collateral as directed by the
Agent and make it available at a place designated by the Agent which is, in the
Agent's opinion, reasonably convenient to the Agent and the Grantors, whether
at the premises of a Grantor or otherwise, (ii) to the extent permitted by
applicable law, enter, with or without process of law and without breach of the
peace, any premise where any of the Collateral is or may be located and,
without charge or liability to the Agent, seize and remove such Collateral from
such premises, (iii) have access to and use the Grantors' books and records,
computers and software relating to the Collateral, (iv) prior to the
disposition of the Collateral, store or transfer such Collateral without charge
in or by means of any storage or transportation facility owned or leased by the
Grantors, process, repair or recondition such Collateral or otherwise prepare
it for disposition in any manner and to the extent the Agent deems ap-





                                       16
<PAGE>   17
propriate and, in connection with such preparation and disposition, use without
charge any trademark, trade name, copyright, patent or technical process used
by the Grantors and (v) prior to the disposition of any pay phones, manage and
operate those pay phones, collect all payments, coins, income and profits from
those pay phones or that may otherwise relate to any Telephone Placement
Agreements, arrange for alternate telephone service with respect to any pay
phones and exercise any other right or remedy of a Grantor under, or with
respect to, any Telephone Placement Agreement (all at the expense of the
Grantors).  Should the Agent (or any successor or assign of the Agent or any
agent or designee of any of the foregoing) notify any Person who is a party to
a Telephone Placement Agreement that an Event of Default has occurred and is
continuing, that Person is hereby irrevocably authorized and instructed to
follow any direction that it may receive in that notice (or any subsequent
notice) relating to that Telephone Placement Agreement and permit the Agent (or
any successor or assign or designee of Agent) to exercise all of any  Grantor's
rights and remedies under that Telephone Placement Agreement as described
above.

                 (c)      Without limiting the generality of the foregoing, if
any Event of Default has occurred and is continuing:

                             (i)  the Agent may license, or sublicense, whether
         general, special or otherwise, and whether on an exclusive or
         non-exclusive basis, any patents or Trademarks included in the
         Collateral throughout the world for such term or terms, on such
         conditions and in such manner as the Agent shall in its sole
         discretion determine;

                             (ii) the Agent may (without assuming any
         obligations or liability thereunder), at any time and from time to
         time, enforce (and shall have the exclusive right to enforce) against
         any licensee or sublicensee all rights and remedies of the Grantors
         in, to and under any patent licenses or Trademark Licenses and take or
         refrain from taking any action under any thereof, and each Grantor
         hereby releases the Agent and each of the Lenders from, and agrees to
         hold the Agent and each of the Lenders free and harmless from and
         against any claims arising out of, any lawful action so taken or
         omitted to be taken with respect thereto EXCEPT FOR the Agent's or
         such Lender's bad faith, gross negligence or wilful misconduct as
         determined by a final and nonappealable decision of a court of
         competent jurisdiction; and

                             (iii)         upon request by the Agent, the
         Grantors will execute and deliver to the Agent powers of attorney, in
         form and substance satisfactory to the Agent, for the implementation
         of any lease, assignment, license, sublicense, grant of option, sale
         or other disposition of a patent or Trademark.  In the event of any
         such disposition pursuant to





                                       17
<PAGE>   18
         this Section, the Grantors shall supply their know-how and expertise
         relating to the manufacture and sale of the products bearing
         Trademarks or the products or services made or rendered in connection
         with patents, and its customer lists and other records relating to
         such patents or Trademarks and to the distribution of said products,
         to the Agent.

         SECTION 9.  LIMITATION ON DUTY OF AGENT IN RESPECT OF COLLATERAL.
Beyond reasonable care in the custody thereof, the Agent shall have no duty as
to any Collateral in its possession or control or in the possession or control
of any agent or bailee or any income thereon or as to the preservation of
rights against prior parties or any other rights pertaining thereto.  The Agent
shall be deemed to have exercised reasonable care in the custody of the
Collateral in its possession if the Collateral is accorded treatment
substantially equal to that which it accords its own property, and the Agent
shall not be liable or responsible for any loss or damage to any of the
Collateral, or for any diminution in the value thereof, by reason of the act or
omission of any  warehouseman, carrier, forwarding agency, consignee or other
agent or bailee selected by the Agent in good faith.

         SECTION 10.  APPLICATION OF PROCEEDS.  Upon the occurrence and during
the continuance of an Event of Default, the proceeds of any sale of, or other
realization upon, all or any part of the Collateral of any Grantor shall be
applied by the Agent in the following order of priorities:

                 FIRST, to payment of the reasonable out-of-pocket expenses of
         such sale or other realization, including reasonable compensation to
         agents and counsel for the Agent, and all reasonable out-of-pocket
         expenses, liabilities and advances incurred or made by the Agent in
         connection therewith, and any other unreimbursed expenses for which
         the Agent or any Lender is to be reimbursed pursuant to Section 9.3 of
         the Credit Agreement, or SECTION 13 hereof or any corresponding
         provision of any of the other Loan Documents;

                 SECOND, to the ratable payment of accrued but unpaid interest
         (including post-petition interest) and fees constituting Secured
         Obligations of such Grantor;

                 THIRD, to the ratable payment of unpaid principal of the
         Secured Obligations of such Grantor;

                 FOURTH, to the ratable payment of all other Secured
         Obligations of such Grantor, until all such Secured Obligations shall
         have been paid in full; and

                 FINALLY, to payment to such Grantor or its successors or
         assigns, or as a court of competent jurisdiction





                                       18
<PAGE>   19
         may direct, of any surplus then remaining from such proceeds.

The Agent may make distributions hereunder in cash or in kind or, on a ratable
basis, in any combination thereof.

         SECTION 11.  CONCERNING THE AGENT.  The provisions of Article 8 of the
Credit Agreement shall inure to the benefit of the Agent in respect of this
Agreement and shall be binding upon the parties to the Credit Agreement in such
respect.  In furtherance and not in derogation of the rights, privileges and
immunities of the Agent therein set forth:

                 (a)      The Agent is authorized to take all such action as is
provided to be taken by it as Agent hereunder or otherwise permitted under the
Credit Agreement and all other action reasonably incidental thereto.  As to any
matters not expressly provided for herein or therein, the Agent may request
instructions from the Lenders and shall act or refrain from acting in
accordance with written instructions from the Required Lenders or,  in the
absence of such instructions, in accordance with its discretion.

                 (b)      The Agent shall not be responsible for the existence,
genuineness or value of any of the Collateral or for the validity, perfection,
priority or enforceability of the Security Interests, whether impaired by
operation of law or by reason of any action or omission to act on its part.
The Agent shall have no duty to ascertain or inquire as to the performance or
observance of any of the terms of this Agreement by the Grantors.

         SECTION 12.  APPOINTMENT OF CO-AGENTS.  At any time or times, in order
to comply with any legal requirement in any jurisdiction, the Agent may appoint
another bank or trust company or one or more other Persons reasonably
acceptable to the Required Lenders, either to act as co-agent or co-agents,
jointly with the Agent, or to act as separate agent or agents on behalf of the
Agent and the Lenders with such power and authority as may be necessary for the
effectual operation of the provisions hereof and specified in the instrument of
appointment (which may, in the discretion of the Agent, include provisions for
the protection of such co-agent or separate agent similar to the provisions of
SECTION 11).

         SECTION 13.  EXPENSES.  In the event that any Grantor fails to comply
with the provisions of the Credit Agreement, this Agreement or any other Loan
Document, such that the value of any Collateral or the validity, perfection,
rank or value of the Security Interests are thereby diminished or potentially
diminished or put at risk, the Agent if requested by the Required Lenders may,
but shall not be required to, effect such compliance on behalf of such Grantor,
and the Grantors shall reimburse the Agent, jointly and severally, for the
reasonable costs thereof on demand.  All reasonable insurance expenses and all
reasonable expenses of





                                       19
<PAGE>   20
protecting, storing, warehousing, appraising, insuring, handling, maintaining
and shipping the Collateral, any and all excise, stamp, intangibles, transfer,
property, sales, and use taxes imposed by any state, federal, or local
authority or any other Governmental Authority on any of the Collateral, or in
respect of periodic appraisals and inspections of the Collateral to the extent
the same may be requested by the Required Lenders from time to time (provided,
however, that unless an Event of Default has occurred and is continuing the
Required Lenders may only request two such appraisals and inspections during
any Fiscal Year), or in respect of the sale or other disposition thereof, shall
be borne and paid by the Grantors; and if the Grantors fail promptly to pay any
portion thereof when due, the Agent or any Lender may, at its option, but shall
not be required to, pay the same and charge the Grantors' accounts therefor,
and the Grantors agree to reimburse the Agent or such Lender therefor on
demand.  All sums so paid or incurred by the Agent or any Lender for any of the
foregoing and any and all other sums for which the Grantors may become liable
hereunder and all reasonable costs and expenses (including attorneys' fees,
legal expenses and court costs) incurred by the Agent or any Lender in
enforcing or protecting the  Security Interests or any of their rights or
remedies thereon shall be payable by the Grantors on demand and shall bear
interest (after as well as before judgment) until paid at the rate set forth in
Section 3.4.3 of the Credit Agreement and shall be additional Secured
Obligations hereunder.

         SECTION 14.  TERMINATION OF SECURITY INTERESTS; RELEASE OF COLLATERAL.
Upon the repayment in full of all Secured Obligations and the termination of
the Commitments, the Security Interests shall terminate and all rights to the
Collateral shall revert to the Grantors.  At any time and from time to time
prior to such termination of the Security Interests, the Agent may release any
of the Collateral with the prior written consent of the Required Lenders;
PROVIDED, HOWEVER, that the Security Interest of the Agent in any Collateral
constituting an asset of which the Grantors may dispose under Section 6.2.11 of
the Credit Agreement shall automatically terminate and be released upon such
disposition by the Grantors without the necessity of any further action or
consent by the Agent or any Lender.  Upon any such termination of the Security
Interests or release of Collateral, the Agent will, at the expense of the
Grantors, execute and deliver to the Grantors such documents as the Grantors
shall reasonably request, including but not limited to a UCC-3 termination
statement, to evidence the termination of the Security Interests or the release
of such Collateral, as the case may be.

         SECTION 15.  NOTICES.  All notices hereunder shall be in writing or by
telecopy and shall be sufficiently given to the Agent, the Lenders or the
Grantors if addressed or delivered to them at, in the case of the Borrower, the
Agent and the Lenders, their respective addresses and telecopier numbers
specified in





                                       20
<PAGE>   21
Section 9.2 of the Credit Agreement (in each case with copies addressed as
provided in Section 9.2 of the Credit Agreement), and, in the case of the
Grantors that are Subsidiaries of the Borrower at, their respective addresses
and telecopier numbers specified in Section 15 of the Subsidiary Guaranty (in
each case with copies addressed as provided in Section 15 of the Subsidiary
Guaranty), or at such other address as any party may designate to any other
party by written notice.  All such notices and communications shall be deemed
to have been duly given:  at the time delivered by hand, if personally
delivered; when received if deposited in the mail, postage prepaid; when
transmission is verified, if telecopied; and on the next Business Day, if
timely delivered to an air courier guaranteeing overnight delivery.

         SECTION 16.  WAIVERS, NON-EXCLUSIVE REMEDIES.  No failure on the part
of the Agent to exercise, and no delay in exercising and no course of dealing
with respect to, any right under the Credit Agreement, this Agreement or any
other Loan Document shall operate as a waiver thereof; nor shall any single or
partial exercise by the Agent or any Lender of any right under the Credit
Agreement, this Agreement or any other Loan Document preclude any other or
further exercise thereof or the exercise of any other right.  The rights in
this Agreement, the Credit Agreement and the other Loan  Documents are
cumulative and are not exclusive of any other remedies provided by law.  This
Agreement is a Loan Document executed pursuant to the Credit Agreement.

         SECTION 17.  SUCCESSORS AND ASSIGNS.  This Agreement is for the
benefit of the Agent and the Lenders and their permitted successors and
assigns, and in the event of an assignment of all or any of the Secured
Obligations, the rights hereunder, to the extent applicable to the indebtedness
so assigned, may be transferred with such indebtedness.  This Agreement shall
be binding on the Grantors and their successors and assigns; PROVIDED, HOWEVER,
that the Grantors may not assign any of their rights or obligations hereunder
without the prior written consent of the Agent and the Lenders.

         SECTION 18.  CHANGES IN WRITING.  Neither this Agreement nor any
provision hereof may be changed, waived, discharged or terminated orally, but
only in writing signed by the Grantors and the Agent with the consent of the
Required Lenders.

         SECTION 19.  GOVERNING LAW.  THIS AGREEMENT SHALL BE CONSTRUED IN
ACCORDANCE WITH AND GOVERNED BY THE LAWS OF THE STATE OF NEW YORK, EXCEPT TO
THE EXTENT THAT PERFECTION (AND THE EFFECT OF PERFECTION AND NONPERFECTION) AND
CERTAIN REMEDIES MAY BE GOVERNED BY THE LAWS OF ANY JURISDICTION OTHER THAN NEW
YORK.

         SECTION 20.  SEVERABILITY.  If any provision hereof is invalid and
unenforceable in any jurisdiction, then, to the fullest extent permitted by
law, (i) the other provisions hereof shall remain in





                                       21
<PAGE>   22
full force and effect in such jurisdiction and shall be liberally construed in
favor of the Agent and the Lenders in order to carry out the intentions of the
parties hereto as nearly as may be possible; and (ii) the invalidity or
unenforceability of any provision hereof in any jurisdiction shall not affect
the validity or enforceability of such provision in any other jurisdiction.

         SECTION 21.      SUPPLEMENT.  In the event that any Subsidiary of the
Borrower is required, under the terms of the Credit Agreement or otherwise, to
grant a security interest in Collateral, such Subsidiary shall become a Grantor
hereunder and shall be bound by all of the terms and conditions hereof, upon
the delivery to the Agent of an executed counterpart of a Supplement to this
Security Agreement in the form of EXHIBIT A attached hereto.

of any event) to any director, officer or employee of the Company or any
Subsidiary.

                 (d)      ABSENCE OF TAKEOVER STATUTES.  The Board of Directors
of the Company has approved for purposes of Chapter 1704 of the Ohio Revised
Code (Transactions Involving Interested Shareholders) the transactions
contemplated by this Agreement, the other Warrant Documents and the Loan
Documents and the issuance of the Warrant Securities and any shares of capital
stock to be issued pursuant to the Loan Documents and upon conversion of any
such shares.  The provisions of Ohio Revised Code Section 1707.041 with respect
to "control bids" as defined in Ohio Revised Code Section 1707.01(V)(1) do not
apply to the transactions  contemplated by the Warrant Agreement, the other
Warrant Documents and the Loan Documents or the issuance of the Warrant
Securities and any shares of Stock to be issued pursuant to the Loan Documents
or upon conversion of such shares.  No other "fair price," "moratorium,"
"control share acquisition," "business combination," "shareholder protection,"
or similar antitakeover statute will apply to any Holder as a result of this
Agreement, any of the other Warrant Documents or any of the Loan Documents or
the authorization or issuance of the Warrant Securities or any shares of
capital stock to be issued pursuant to the Loan Documents.  The Company is not
a party to, and is not subject to, any rights plan, rights agreement or similar
agreement, arrangement or understanding.

                 (e)      COMMUNICATIONS ACT.  None of the Company and its
Subsidiaries holds any licenses or conducts any business which would result in
the application of Section 310 of the Communications Act of 1934 as a result of
this Agreement, any of the other Warrant Documents, or any of the Loan
Documents or the authorization or issuance of the Warrant Securities or any
shares of capital stock to be issued pursuant to the Loan Documents.

                 (f)      VALIDITY, ETC.  This Agreement constitutes, and each
of the other Warrant Documents will upon the execution and delivery thereof
constitute, the legal, valid and binding obligations of the Company enforceable
in accordance with their respective terms, in each case subject to (i) the
effect of any applicable bankruptcy, insolvency, moratorium or similar laws
affecting creditors' rights generally, and (ii) the effect of general principles
of equity (regardless of whether considered in a proceeding in equity or at
law).

of the Warrant Certificates therefor in accordance with the terms hereof, the

                 (j)      NO INTEGRATION OF ISSUE.  Neither the Company nor any
Person authorized or employed by the Company as agent, broker or otherwise in
connection with the offering of the Warrants has offered the Warrants for sale
to, or solicited any offers to buy the Warrants from, or otherwise approached

of such Preferred Stock), except such dividends and distributions as accrue and
cumulate in accordance with the terms of such Preferred Stock as in effect on

apply, any of its funds, properties or assets to the purchase, redemption,

                 (j)      ANTITAKEOVER STATUTES.  The Company shall take all
action necessary to avoid the application of any "fair price," "moratorium,"
"control share acquisition," "business combination," "shareholder protection" or
similar antitakeover statute to the transactions contemplated by this Agreement,
any of the other Warrant Documents or any of the Loan Documents (including the
issuance of the Warrant Securities or any shares of capital stock to be issued
pursuant to the Loan Documents).

                 (k)      REDEMPTIONS; EXTRAORDINARY DIVIDENDS.  The Company (i)

result in the application of Section 310 of the Communications Act of 1934 (or
any similar provision) as a result of this Agreement, any of the other Warrant
Documents, or any of the Loan Documents or the authorization or issuance of the
Warrant Securities or any shares of capital stock to be issued pursuant to the
Loan Documents.

                 (m)      GOVERNMENTAL APPROVALS.  The Company will, and will


                                      22

<PAGE>   26

cooperate with the Holders to, secure all necessary consents, approvals,
authorizations and exemptions from all governmental authorities (including the
making of all filings under the Hart-Scott-Rodino Antitrust Improvements Act of
1976, as amended (the "HSR Act")) in connection with the exercise of the
Warrants, the issuance of shares of Series A Special Preferred Stock upon

                 SECTION 7.  WARRANT CERTIFICATES.  The Warrant Certificates to
be delivered pursuant to this Agreement shall be in registered form only and
shall be in the form set forth as EXHIBIT A attached hereto.

                 SECTION 8.  EXECUTION OF WARRANT CERTIFICATES.  Warrant
Certificates shall be signed on behalf of the Company by its Chairman of the
Board or its President or a Vice President and by its Secretary or an Assistant
Secretary under its corporate seal.  Each such signature upon the Warrant
Certificates may be in the form of a facsimile signature of the Chairman of the
Board, President, Vice President, Secretary or Assistant Secretary and may be
printed or otherwise reproduced on the Warrant Certificates and for that
purpose the Company may adopt and use the facsimile signature of any person who
shall have been Chairman of the Board, President, Vice President, Secretary or
Assistant Secretary, notwithstanding the fact that at the time the Warrant
Certificates shall be delivered or disposed of such person shall have ceased to
hold such office.  The seal of the Company may be in the form of a facsimile
thereof and may be impressed, affixed, imprinted or otherwise reproduced on the
Warrant Certificates.

                 In case any officer of the Company who shall have signed any
of the Warrant Certificates shall cease to be such officer before the Warrant
Certificates so signed shall have been disposed of by the Company, such Warrant
Certificates nevertheless may be delivered or disposed of as though such person
had not ceased to be such officer of the Company; and any Warrant Certificate
may be signed on behalf of the Company by any person who, at the actual date of
the execution of such Warrant Certificate, shall be a proper officer of the
Company to sign such Warrant Certificate although at the date of the execution
of this Agreement such person was not such an officer.

                 SECTION 9.  REGISTRATION.  The Company shall number and

                                      23

<PAGE>   27

register the Warrant Certificates in a register as they are issued.  The
Company may deem and treat the registered holder(s) of the Warrant Certificates
as the absolute owner(s) thereof (notwithstanding any notation of ownership or
other writing thereon made by anyone) for all purposes and shall not be
affected by any notice to the contrary.

                 SECTION 10.  REGISTRATION OF TRANSFERS AND EXCHANGES.  The
Company shall from time to time register the transfer of any outstanding
Warrant Certificates in a Warrant register to be maintained by the Company upon
surrender of such Warrant Certificates accompanied by a written instrument or
instruments of transfer in form reasonably satisfactory to the Company, duly
executed by the registered Holder or Holders thereof or by the duly appointed
legal representative thereof or by a duly authorized attorney.  Upon any such
registration of transfer, a new Warrant Certificate shall be issued to the
transferee(s) and the surrendered Warrant Certificate shall be cancelled and
disposed of by the Company.  The Company agrees that it will make the Warrant
register available for inspection by the Holders during normal business hours at
its office and that the Holders may rely on the Warrant register for purposes of
complying with the preceding sentence.

                 The Warrants shall be transferable in whole or in part and, in
the event that a Warrant Certificate is transferred in respect of fewer than
all the Warrants evidenced by the Warrant Certificate, a new Warrant
Certificate evidencing the remaining Warrant or Warrants will be issued and
delivered pursuant to the provisions of this SECTION 10 and of SECTION 8.

                 If such transfer of Warrants is not made pursuant to an
effective registration statement under the Securities Act, the Holder will, if
reasonably requested by the Company, deliver to the Company an opinion of
counsel, which may be counsel to the Holder but which counsel must be
reasonably satisfactory to the Company (provided that King & Spalding and
Lowenstein, Sandler, Kohl, Fisher & Boylan  shall be deemed reasonably
satisfactory), reasonably satisfactory in form, scope and substance to the
Company, that the Warrants may be sold without registration under the
Securities Act, as well as:

                          (1)     an investment covenant reasonably
satisfactory to the Company signed by the proposed transferee (except that no
such covenant will be required in connection with a transfer effected in
accordance with Rule 144A under the Securities Act); and

                          (2)     an agreement by such transferee to the
impression of the restrictive legends set forth below on the Warrant
Certificate.

<PAGE>   28
                 The Holders agree that each Warrant Certificate and each
certificate representing Warrant Shares will bear the following
legend (the "SECURITIES LEGEND"):


                           "THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE
                           NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF
                           1933, AS AMENDED, OR ANY STATE SECURITIES LAWS.
                           SAID SECURITIES MAY NOT BE SOLD OR TRANSFERRED IN
                           THE ABSENCE OF SUCH REGISTRATION OR AN EXEMPTION, OR
                           AN OPINION OF COUNSEL (WHICH MAY BE COUNSEL TO THE
                           HOLDER) AS TO AN EXEMPTION, FROM THE REGISTRATION
                           PROVISIONS OF SAID ACT OR LAWS."

Notwithstanding the foregoing provisions of this SECTION 10, the restrictions
upon the transferability of the Warrant Certificates and the Securities Legend
requirement set forth above in this SECTION 10 shall terminate as to any of the
Warrant Securities (i) when and so long as such Warrant Security shall have
been effectively registered under the Securities Act and disposed of pursuant
thereto or (ii) when the Company shall have received an opinion of counsel
reasonably satisfactory to it that such Securities Legend is not required in
order to ensure compliance with the Securities Act.  Whenever the restrictions
imposed by  this SECTION 10 shall terminate as to any Warrant Security, as
hereinabove provided, the Holder thereof shall be entitled to receive from the
Company, at the expense of the Company, a new Warrant Certificate or
certificate for Warrant Shares bearing the following legend in place of the
Securities Legend set forth above:

                          "THE RESTRICTIONS ON TRANSFERABILITY OF THE
                          SECURITIES REPRESENTED BY THIS CERTIFICATE TERMINATED
                          ON ______________, 19__, AND ARE OF NO FURTHER FORCE
                          AND EFFECT."

                 The Holders further agree that each Warrant Certificate and
each certificate representing Warrant Shares will bear the following legend:

                          "THE SECURITIES REPRESENTED BY THIS CERTIFICATE ARE
                          SUBJECT TO THE TERMS OF A WARRANT PURCHASE
                          AGREEMENT, DATED AS OF MARCH 15, 1996, BETWEEN
                          PHONETEL TECHNOLOGIES, INC. (THE "COMPANY") AND
                          INTERNATIONALE NEDERLANDEN (U.S.) CAPITAL CORPORATION
                          ("ING") AND CERBERUS PARTNERS, L.P. ("CERBERUS"), AND
                          A REGISTRATION RIGHTS AGREEMENT, DATED AS OF MARCH 15,
                          1996, AMONG THE COMPANY, ING 


                                      25

<PAGE>   29
                          AND CERBERUS, COPIES OF EACH OF WHICH ARE ON
                          FILE AT THE MAIN OFFICE OF THE COMPANY.  ANY SALE OR
                          TRANSFER OF THE SECURITIES EVIDENCED BY THIS
                          CERTIFICATE IS SUBJECT TO THE TERMS OF THOSE
                          AGREEMENTS AND ANY SALE OR TRANSFER OF SUCH SECURITIES
                          IN VIOLATION OF SAID AGREEMENTS SHALL BE INVALID."

                 Warrant Certificates may be exchanged at the option of the
Holder(s) thereof when surrendered to the Company at its office for another
Warrant Certificate or other Warrant Certificates of like tenor and
representing in the aggregate a like number of Warrants, including, without
limitation, upon an adjustment in the Exercise Price or in the number of
Warrant Shares purchasable upon exercise of the Warrants.  Warrant Certificates
surrendered for exchange shall be cancelled and disposed of by the Company.

                 SECTION 11.  WARRANTS; EXERCISE OF WARRANTS.  Subject to the
terms of this Agreement, each Holder shall have the right, which may be
exercised at any time or from time to time prior to April 1, 2006, to receive
from the Company the number of fully paid and nonassessable Warrant Shares
which such Holder may at the time be entitled to receive on exercise of all or
any part of the Warrants and payment of the Exercise Price then in effect for
such Warrant Shares.

                 A Warrant may be exercised upon surrender to the Company at
its office designated for such purpose (the address of which is set forth in
SECTION 20) of the certificate or certificates evidencing the Warrants to be
exercised with the form of election to purchase attached thereto properly
completed and signed, upon payment to the Company of the Exercise Price for the
number of Warrant Shares in respect of which such Warrants are then exercised.
Payment of the aggregate Exercise Price shall be made in cash or by check
payable to the order of the Company.

                 Upon such surrender of Warrant Certificates and payment of the
Exercise Price, the Company shall issue and cause to be delivered with all
reasonable dispatch (and in any event within five (5) Business Days of such
surrender and payment) to or, subject to the provisions of SECTION 10, upon the
written order of the Holder, and in the name of the Holder or the Holder's
nominee, a certificate or certificates for the number of full Warrant Shares
issuable upon the exercise of such Warrants together with such other property
(including cash) and securities as may then be deliverable upon such exercise,
including cash for fractional Warrant Shares as provided in SECTION 16.  Such
certificate or certificates shall be deemed to have been issued and the Person
so named therein shall be deemed to have become a holder of record of such
Warrant Shares as of the date of the surrender of such Warrant Certificates and
payment of the Exercise Price.


                                      26

<PAGE>   30

                 The Warrants shall be exercisable, at the election of the
Holders thereof, either in full or from time to time in part, and, in the event
that a Warrant Certificate is exercised in respect of fewer than all of the
Warrant Shares issuable pursuant to such Warrant Certificate at any time prior
to the date of expiration of the Warrants, a new Warrant Certificate evidencing
the remaining Warrant or Warrants will be issued and delivered pursuant to the
provisions of this SECTION 11 and of SECTION 8.

                 All Warrant Certificates surrendered upon exercise of Warrants
shall be cancelled and disposed of by the Company.  The Company shall keep
copies of this Agreement and any notices received hereunder available for
inspection during normal business hours at its office.  The Company will
furnish, at its expense, copies of this Agreement and all such notices, upon
request, to any Holder of any Warrant Certificates.

                 SECTION 12.  PAYMENT OF TAXES.  The Company will pay all stamp
and transfer taxes in connection with the issuance, sale and delivery of the
Warrants hereunder, as well as all such taxes attributable to the initial
issuance of Warrant Shares upon the exercise of Warrants and payment of the
Exercise Price and upon the issuance of shares of Common Stock upon the
conversion of shares of Series A Special Preferred Stock.  The Company will
not, however, be required to pay any tax or other similar charges imposed in
connection with any transfer of any Warrant Securities.  Nothing herein shall
be construed as requiring the Company to pay any taxes imposed in respect of
income realized by any Holder upon  the purchase, transfer or exercise of
Warrants or upon conversion of shares of Series A Special Preferred Stock.

                 SECTION 13.  MUTILATED OR MISSING WARRANT CERTIFICATES.  In
case any of the Warrant Certificates shall be mutilated, lost, stolen or
destroyed, upon receipt of an affidavit and reasonable indemnity from the
holder thereof stating that such Warrant Certificate has been mutilated, lost,
stolen or destroyed the Company shall issue, in exchange and substitution for
and upon cancellation of the mutilated Warrant Certificate, or in lieu of and
substitution for the Warrant Certificate lost, stolen or destroyed, a new
Warrant Certificate of like tenor and representing an equivalent number of
Warrants.

                 SECTION 14.  RESERVATION OF WARRANT SHARES.  The Company will
at all times reserve and keep available, free from preemptive or similar
rights, out of the aggregate of its authorized but unissued capital stock or
its authorized and issued capital stock held in its treasury, for the purpose
of enabling it to satisfy any obligation to issue Warrant Shares upon exercise
of Warrants, (i) the maximum number of shares of each class of capital stock
constituting a part of the Warrant Shares which may then be deliverable upon
the exercise of all outstanding Warrants and (ii) the maximum number of shares
of each class of Stock of the 


                                      27

<PAGE>   31

Company which may then be delivered upon the conversion into Common Stock of all
issued Warrant Shares.  The Company shall cause all shares of Common Stock into
which Warrant Shares are convertible to be (x) listed (or to be listed subject
to notice of issuance) on each securities exchange on which shares of Common
Stock are listed, or (y) admitted for trading in any inter-dealer quotation
system on which shares of Common Stock are traded.

                 The Company or, if appointed, the transfer agent for shares of
each class of capital stock of the Company (the "TRANSFER AGENT") and every
subsequent transfer agent for any shares of the Company's capital stock
issuable upon the exercise of the Warrants will be irrevocably authorized and
directed at all times to reserve such number of authorized shares as shall be
required for such purpose.  The Company will keep a copy of this Agreement on
file with the Transfer Agent and with every subsequent transfer agent for any
shares of the Company's capital stock issuable upon the exercise of the rights
of purchase represented by the Warrants or of the rights of conversion of the
Warrant Shares.  The Company will furnish such Transfer Agent a copy of all
notices of adjustments, and certificates related thereto, transmitted to each
Holder pursuant to SECTION 17.

                 Before taking any action which would cause an adjustment
pursuant to SECTION 15 to reduce the Exercise Price below the then par value
(if any) of the Warrant Shares, the Company will take any corporate action
which may, in the opinion of its counsel (which may be counsel employed by the
Company), be necessary in order that the Company may validly and legally issue
fully paid  and nonassessable Warrant Shares at the Exercise Price as so
adjusted.

                 SECTION 15.  ADJUSTMENT OF EXERCISE PRICE AND NUMBER OF
WARRANT SHARES ISSUABLE.  The Exercise Price and the number of Warrant Shares
issuable upon the exercise of each Warrant are subject to adjustment from time
to time upon the occurrence of any of the events enumerated in this SECTION 15.

                 (a)  REORGANIZATION OF THE COMPANY

                 In the event of any capital reorganization, recapitalization
or reclassification of the capital stock of the Company, or consolidation,
merger or amalgamation of the Company with another entity, any acquisition of
capital stock of the Company by means of a share exchange, or the sale, lease,
transfer, conveyance or other disposition of all or substantially all of its
assets to another entity, then, as a condition of such reorganization,
recapitalization, reclassification, consolidation, merger, amalgamation, share
exchange or sale, lease, transfer, conveyance or other disposition, lawful and
adequate provision shall be made whereby the Holders of the Warrant
Certificates shall thereafter have the right to purchase and receive, on the
basis and upon the terms and conditions specified in this Agreement and in 

                                      28

<PAGE>   32

lieu of the Warrant Shares immediately theretofore purchasable and receivable
upon the exercise of the rights represented by the Warrants, (i) such shares of
stock, securities, cash or property as may be issued or payable with respect to
or in exchange for a number of outstanding Warrant Shares equal to the number of
Warrant Shares immediately theretofore purchasable and receivable upon the
exercise of the rights represented by the Warrant Certificates had such
reorganization, recapitalization, reclassification, consolidation, merger,
amalgamation, share exchange or sale, lease, transfer, conveyance or other
disposition not taken place, and (ii) if such consolidation, merger,
amalgamation, share exchange, sale, lease, transfer, conveyance or other
disposition is with any Person (or any Affiliate of such Person) who shall have
made a purchase, tender or exchange offer which was accepted by the holders of
not less than twenty percent (20%) of the outstanding shares of Common Stock,
the Holders of the Warrants shall have been given a reasonable opportunity (and,
in no event, less than 30 days) to elect to receive, either (x) the stock,
securities, cash or property it would have received pursuant to clause (i)
immediately preceding or (y) the stock, securities, cash or property issued to
previous holders of the Common Stock in accordance with such offer, or the
equivalent thereof.  In any such case appropriate provision shall be made with
respect to the rights and interests of the Holders of the Warrants to the end
that the provisions hereof (including, without limitation, provisions for
adjustment of the Exercise Price and of the number and type of securities
purchasable upon the exercise of the Warrants) shall thereafter be applicable,
as nearly as may be, in relation to any shares of stock, securities, cash or
property thereafter deliverable upon  the exercise of the Warrants.  The Company
shall not effect any such consolidation, merger, amalgamation, share exchange or
sale, lease, transfer, conveyance or other disposition unless prior to or
simultaneously with the consummation thereof the successor entity (if other than
the Company) resulting from such consolidation, merger or amalgamation, share
exchange or the entity purchasing or otherwise acquiring such assets or shares
(i) shall assume by a supplemental Warrant Agreement, satisfactory in form,
scope and substance to the Holders (which shall be mailed or delivered to the
Holders of the Warrants at the last address of such Holders appearing on the
books of the Company) the obligation to deliver to such Holders such shares of
stock, securities, cash or property as, in accordance with the foregoing
provisions, such Holders may be entitled to purchase (the "SUBSTITUTE
SECURITIES") and (ii) shall assume all of the other obligations of the Company
set forth in this Agreement and the Registration Rights Agreement.  Following
such assumption such obligations shall  apply to the Substitute Securities
rather than to the Warrants and the Warrant Shares.  The foregoing provisions of
this paragraph shall similarly apply to successive reorganizations,
recapitalizations, reclassifications, consolidations, mergers, amalgamations,
share exchanges, sales, leases, transfers, conveyances or other dispositions.





                                       29
<PAGE>   33
                 If the issuer of securities deliverable upon exercise of
Warrants under the supplemental Warrant Agreement is an Affiliate of the
formed, surviving, transferee or lessee entity, such issuer shall join the
supplemental Warrant Agreement.

                 (b)      WHEN ISSUANCE OR PAYMENT MAY BE DEFERRED

                 In any case in which this SECTION 15 shall require that an
adjustment in the Exercise Price be made effective as of a record date for a
specified event, the Company may elect to defer until the occurrence of such
event (i) issuing to the Holder of any Warrant exercised after such record date
the Warrant Shares issuable upon such exercise over and above the Warrant
Shares issuable upon such exercise on the basis of the Exercise Price prior to
such adjustment and (ii) paying to such Holder any amount in cash in lieu of a
fractional share pursuant to SECTION 16; PROVIDED, HOWEVER, that the Company
shall deliver to such Holder a bill or other appropriate instrument evidencing
such Holder's right to receive such additional Warrant Shares and cash upon the
occurrence of the event requiring such adjustment.

                 SECTION 16.      FRACTIONAL INTERESTS.  The Company shall not
be required to issue fractional Warrant Shares on the exercise of Warrants.  If
more than one Warrant shall be presented for exercise in full at the same time
by the same Holder, the number of full Warrant Shares which shall be issuable
upon exercise thereof shall be computed on the basis of the aggregate number of
Warrant Shares purchasable on exercise of the Warrants so presented.  If any
fraction of the Warrant Shares would, except for the provisions of this SECTION
16, be issuable on the exercise of  any Warrants (or specified portion
thereof), the Company shall pay an amount in cash equal to the product of (x)
the Fair Market Value per Share on the day immediately preceding the date the
Warrant is presented for exercise, multiplied by (y) the Conversion Rate,
multiplied by (z) such fraction.

                 SECTION 17.      NOTICE TO WARRANT HOLDERS.  Upon any
adjustment of the Exercise Price or number of Warrant Shares purchasable upon
exercise of the Warrants pursuant to SECTION 15 or subparagraph (1)(vii) of the
Certificate of Amendment and as otherwise required by SECTION 15 or
subparagraph (1)(vii) of the Certificate of Amendment, the Company shall
promptly thereafter (i) upon the reasonable request of the Required Holders,
cause to be filed with the Company a certificate of the independent certified
public accountants for the Company setting forth the Exercise Price and the
number and type of securities or other property constituting Warrant Shares
after such adjustment and setting forth in reasonable detail the method of
calculation and the facts upon which such calculations are based and, in the
case of an adjustment pursuant to SECTION 15(A) or subparagraph (1)(vii) of the
Certificate of Amendment, setting forth the number and type of securities or
other property constituting Warrant Shares (or 

                                      30

<PAGE>   34

portion thereof) issuable, after such adjustment in the Exercise Price and
number of Warrant Shares purchasable upon exercise of the Warrants, upon
exercise of a Warrant and payment of the adjusted Exercise Price, and (ii) cause
to be given to each of the Holders of the Warrant Certificates written notice of
such adjustments, together with a copy of such certificate.  Where appropriate,
such notice may be given in advance and included as a part of the notice
required to be given under the other provisions of this SECTION 17.

                 In the event:

                 (a)      the Company shall authorize the issuance to holders
(although not necessarily to all such holders) of shares of Common Stock or
rights, options or warrants to subscribe for or purchase or otherwise acquire
shares of Common Stock or of any other securities or property (including
securities of any other issuer) or of any other subscription rights, options or
warrants; or

                 (b)      the Company shall authorize the payment of any
dividend or distribution to holders of shares of Common Stock of cash, capital
stock or other securities or property (including securities of any other
issuer) of the Company; or

                 (c)      of any capital reorganization, reclassification or
recapitalization of the capital stock of the Company, or any amalgamation,
consolidation or merger to which the Company is a party, or any acquisition of
capital stock of the Company through a share exchange, or of the sale, lease,
conveyance, transfer or other disposition of the properties and assets of the
Company substantially as an entirety, or a purchase, tender or exchange offer
for shares of Common Stock or other securities constituting  part of the
Warrant Shares (whether by the Company or some other party); or

                 (d)      of the voluntary or involuntary dissolution,
liquidation or winding up of the Company; or

                 (e)      the Company proposes to take any action which would
require an adjustment of the Exercise Price or number of Warrant Shares
purchasable upon exercise of the Warrants pursuant to SECTION 15 or
subparagraph (1)(vii) of the Certificate of Amendment;

then the Company shall cause to be given to each of the Holders, at least 20
days prior to the applicable record date hereinafter specified (or promptly in
the case of events for which there is no record date), a written notice stating
(as applicable) (i) the date as of which the holders of record of shares of
Common Stock entitled to receive any such rights, options, warrants or
dividends or distribution are to be determined, (ii) the date on which any such
reclassification, recapitalization or reorganization, consolidation, merger,
amalgamation, share exchange, sale, lease, 

                                      31

<PAGE>   35

conveyance, transfer, disposition, dissolution, liquidation or winding up is
expected to become effective or be consummated, or (iii) the initial expiration
date set forth in any purchase, tender or exchange offer for shares of Common
Stock, and the date as of which it is expected that holders of record of shares
of Common Stock or other securities constituting a part of the Warrant Shares
(or securities into which the Warrant Shares may be converted) shall be entitled
to exchange such shares or securities for securities or other property, if any,
deliverable upon such reclassification, recapitalization, reorganization,
consolidation, merger, amalgamation, share exchange, sale, lease, conveyance,
transfer, disposition, dissolution, liquidation or winding up.

                 Nothing contained in this Agreement or in any of the Warrant
Certificates shall be construed as conferring upon the Holders thereof the
right to vote or to consent as stockholders in respect of the meetings of
stockholders or the election of members of the Board of Directors of the
Company or any other matter, or any rights whatsoever as stockholders of the
Company.

                 SECTION 18.      CASH DISTRIBUTIONS AND DIVIDENDS.  If the
Company pays a dividend or makes a distribution to the holders of its Common
Stock of any securities (other than capital stock for which an adjustment in
the Conversion Rate is made pursuant to subparagraph (1)(vii) of the
Certificate of Amendment) or property (including cash and securities of other
companies) of the Company, or any rights, options or warrants to subscribe for
or purchase securities (other than Common Stock) or property (including
securities of other companies) of the Company, then, simultaneously with the
payment of such dividend or the making of such distribution, and as a condition
precedent to its right to do so, it will pay or distribute to the Holders of
Warrant  Certificates an amount of property (including, without limitation,
cash) and/or securities (including, without limitation, securities of other
companies) of the Company as would have been received by such Holders had they
exercised all of the Warrants represented by the Warrant Certificates and the
Warrant Shares issued upon such exercise had been converted into Common Stock,
in each case immediately prior to the record date (or other applicable date)
used for determining stockholders of the Company entitled to receive such
dividend or distribution.  No adjustment to the Exercise Price shall be made for
the distribution of Convertible Securities or rights, options or warrants to
purchase Convertible Securities of the Company to the Holders pursuant to the
provisions of this SECTION 18.

                 SECTION 19.      PUT RIGHTS; TAG-ALONG RIGHTS AND REGISTRATION
RIGHTS.

                 (a)      PUT BY HOLDERS.

                 Unless the Required Holders have otherwise agreed in 


                                      32

<PAGE>   36
writing, at any time and from time to time on or after (i) the repayment in full
or in part of the Loan in each case utilizing the proceeds of borrowed funds or
the issuance of debt securities  or (ii) the occurrence of an Additional Put
Event, the Put Right shall be exercisable by each of the Holders, PROVIDED,
HOWEVER, that ING agrees not to exercise its Put Right upon the occurrence of an
event specified in clause (i) until an event in clause (ii) occurs if the event
in clause (i) involves the use of proceeds of borrowed funds provided through a
credit facility for which ING serves as the administrative agent or the issuance
of debt securities pursuant to a private placement or public offering for which
ING or one of its Affiliates serves as a co-placement agent or co-lead
underwriter, and PROVIDED, FURTHER, with respect to each event specified in
clauses (i) and (ii) (other than an Additional Put Event within the meaning of
clause (c) of such definition in which case the put may be exercised with
respect to all Warrant Securities), the total number of Warrant Securities that
the Holders shall be entitled to put pursuant to this Section 19 shall not
represent more than the greater of (x) 6% of the shares of Common Stock
outstanding on a fully diluted basis on the date hereof, and (y) 20% of the
Warrant Securities held by such Holders (it being understood that each Holder
shall be entitled to put such Warrant Securities pro rata based upon the number
of Warrant Securities held by it). The Put Right shall be exercised by the
delivery of a Put Notice

                 After receipt of a Put Notice from any Holder, the Company
will promptly (and in any event within ten (10) days) give written notice (the
"EXERCISE NOTICE") to each of the other Holders of Warrant Securities that a
Put Right has been exercised.  Each Holder will have the right to participate
in the Put Right and require the Company to repurchase all or any portion of
such Holder's Warrant Securities by delivering written notice to the Company
within ten (10) days following receipt of the Exercise  Notice.  All such
notices delivered by such other Holders will be deemed to have been delivered
as of the date of the initial Put Notice and taken together will be deemed to
be one exercise of the Put Right.

                 Upon the exercise by a Holder of the Put Right, the Purchase
Price payable to such Holder by the Company for such Holder's Warrant
Securities shall be as follows:

                 (i)      in the case of Warrants, an amount determined by
subtracting (A) the aggregate Exercise Price for such Warrants then in effect
under the Warrant Agreement from (B) the product of (1) the Contract Value per
Share, MULTIPLIED BY (2) the number of shares of Common Stock that may be
acquired upon the conversion by such Holder of the shares of Series A Special
Preferred Stock that would be received upon exercise of such Holder's Warrants
with respect to which the Put Right is being exercised;

                                     33

<PAGE>   37

                (ii)      in the case of Series A Special Preferred Stock, an
amount equal to the product of (A) the Contract Value per Share, MULTIPLIED BY
(B) the number of shares of Common Stock that may be acquired upon the
conversion by such Holder of the shares of Series A Special Preferred Stock
with respect to which the Put Right is being exercised; and

             (iii) in the case of Common Stock, an amount equal to the product
of (A) the Contract Value per Share, multiplied by (B) the number of shares of
Common Stock with respect to which the Put Right is being exercised.

                 Promptly upon the receipt of a Put Notice pursuant to SECTION
19(A) the Company shall cause the Contract Value per Share to be determined,
and shall give written notice of the determination thereof to each Holder,
promptly upon the determination thereof and in any event within thirty (30)
days following the Company's receipt of the Put Notice.

                 The provisions of this SECTION 19(A) shall apply until the
termination of this Agreement pursuant to SECTION 24 to any Person who acquires
in any manner any Warrant Securities from any Holder.

                 (b)  CLOSING.

                 Each closing of the purchase and sale of any Warrant
Securities pursuant to SECTION 19(A) shall take place on a date (a "PUT CLOSING
DATE") which is thirty (30) days after the giving of the Put Notice, provided
that if such day is not a Business Day such closing shall be on the next
succeeding Business Day.  Payment of the Purchase Price shall be due and
payable in full on the Put Closing Date.  The closing of such purchase and sale
of Warrant Securities shall take place at 10:00 a.m. on the Put Closing Date at
such location in Atlanta, Georgia, or New York, New York, as the Required
Holders may reasonably determine and  notify the Company or at such other
location as may be agreed to by the Company and the Required Holders.

                 The Purchase Price shall be paid in full at each such closing,
by wire transfer of immediately available federal funds, and the Warrant
Securities to be repurchased at such closing shall be duly endorsed for
transfer.  Such Warrant Securities shall be free and clear of all liens and
encumbrances of any kind, nature and description, other than applicable
restrictions under federal and state securities laws, and each Holder shall
represent and warrant to the Company to such effect with respect to such
Holder's Warrant Securities.  The Company will pay all stamp and transfer taxes
in connection with the repurchase of the Warrant Securities hereunder.

                 (c)      RESTRICTIONS ON PURCHASE.

<PAGE>   38

                 The Company covenants and agrees that, other than the
Restrictive Provisions, it shall not, and shall not permit any of its
Subsidiaries to, without the prior written consent of the Required Holders,
enter into or agree to become subject to any term, condition, provision or
agreement that would conflict with or restrict in any way the performance of
the Company's obligations under this Agreement or that would by its terms
restrict the availability of Legally Available Funds with which to perform such
obligations.

                 Anything in this Agreement to the contrary notwithstanding,
the Company shall not be required to purchase Warrant Securities under SECTION
19(A) if at the time of closing of the purchase and sale of any Warrant
Securities pursuant to SECTION 19(A) there exists any Restrictions on Purchase.

                 Upon receipt of a Put Notice, if the Company's obligations
under SECTION 19(A) at the time of performance would be subject to Restrictions
on Purchase, then the Company (i) shall promptly use all reasonable efforts
(excluding the payment of waiver, consent or similar transactional fees, but
including reasonable documentation costs and other similar expenses) to cause
the Required Lenders to waive compliance with any such Restrictive Provisions
and/or to amend the Restrictive Provisions so as to permit the purchase of the
Warrant Securities pursuant to this Agreement, (ii) shall not repay, redeem,
purchase or otherwise retire any indebtedness for borrowed money of, or any
debt securities issued by, the Company in an amount or for a price or other
consideration in excess of the principal amount thereof, and (iii) shall not
declare or pay any dividend or distribution on any shares of Stock (other than
dividends that accrue and cumulate on Preferred Stock in accordance with the
terms of such Preferred Stock as is in effect on the date such Put Notice is
received by the Company).

                 If, notwithstanding the Company's reasonable efforts required
under this SECTION 19(C), the Company is unable to  fulfill its obligations
under SECTION 19(A) because of the existence of one or more Restrictions on
Purchase, the Company shall give prompt written notice thereof to each Holder
exercising Put Rights, specifying in reasonable detail the nature thereof and
the extent, if any, to which the Company would be able to fulfill its
obligation to pay the Purchase Price within the Restrictions on Purchase.

                 If any Restrictions on Purchase exist on the proposed Put
Closing Date, then at the sole and independent election of each such Holder,
and pursuant to written notice given by any such Holder to the Company:  (i)
such Holder's Put Right shall remain exercised and the closing of the purchase
and sale of Warrant Securities pursuant to such Holder's Put Right shall be
deferred until not more than five Business Days after all such Restrictions 

                                     35

<PAGE>   39

on Purchase cease to exist; PROVIDED, HOWEVER, that, as and to the extent that
such Restrictions on Purchase cease to exist, the Company shall promptly make
partial payments of the Purchase Price to such Holder, in which case there
shall be a series of such closings, each of which shall take place not more
than five Business Days after such Restrictions on Purchase have ceased to
exist to an extent that would permit such partial payments of the Purchase
Price in increments of not less than $100,000 ("PARTIALLY AVAILABLE FUNDS"); or
(ii) the exercise of such Holder's Put Right shall be rescinded and such Holder
shall reserve its right to exercise the Put Right at any subsequent time.  In
the event that any Holders make the election provided in clause (i) of the
immediately preceding sentence, the Company shall purchase from such selling
Holders that number of Warrant Securities as may be purchased at the Purchase
Price using that portion of Partially Available Funds for such purchase as
equals the product of (a) all Partially Available Funds, and (b) the ratio of
(i) the Warrant Securities originally proposed to be sold by such Holders
electing to sell and not electing to rescind pursuant to clause (ii) of the
immediately preceding sentence, to (ii) the Warrant Securities originally
proposed to be sold by all Holders (treating all Warrants as fully exercised
for the Warrant Shares to which the Holders would be entitled upon exercise of
such Warrants).  Such purchase shall be made from each selling Holder PRO RATA
based on the ratio of (i) the number of Warrant Securities originally proposed
to be sold by such Holder to (ii) the Warrant Securities originally proposed to
be sold by all Holders.

                 None of the provisions of this SECTION 19(C) shall be
construed to limit any other right or remedy under applicable law which any
Holder may have as a result of the failure by the Company to purchase Warrant
Securities as herein provided.

                 (d)      TAG-ALONG RIGHTS.

                 Without limitation to the right of any Holder to exercise its
Put Right pursuant to SECTION 19(A), if at any time the Company or Graf shall
determine to enter into any transaction or series of transactions that would
result in a Change of Control  (a "CHANGE OF CONTROL TRANSACTION") (any third
party proposing to enter into such transaction or transactions with the Company
or Graf being hereinafter referred to in this SECTION 19(D) as a "PROSPECTIVE
PURCHASER"), either the Company or Graf, as the case may be, and in either case
any Prospective Purchaser, shall first give written notice (the "OFFER NOTICE")
to all of the Holders, specifying the name and address of the Prospective
Purchaser and the number of shares, if any, of Stock proposed to be issued,
sold, transferred or otherwise disposed of by the Company or Graf, as
applicable, and setting forth in reasonable detail the price, structure and
other terms and conditions of the Change of Control Transaction, as applicable.
The Offer Notice shall represent the offer (the "OFFER") from the Prospective
Purchaser to each of the Holders of 

                                     36

<PAGE>   40

the right to sell to the Prospective Purchaser as a condition to the
consummation of the proposed transaction described in the Offer Notice, all the
Warrant Securities then owned by each Holder to the Prospective Purchaser and,
at the option of the Holders, on the same terms and conditions (including price
and form of consideration) as are being offered by the Prospective Purchaser to
the Company or Graf, as the case may be, or at the Fair Market Value per Share,
determined as of the date of the Offer Notice.  Each Holder shall have thirty
(30) days from the date of receipt of the Offer Notice to give written notice
of its intention to accept or reject the Offer.  Failure to respond within such
thirty-day period shall be deemed notice of rejection.  In the event that any
Holder gives written notice to the Company or Graf, as the case may be, and the
Prospective Purchaser of its intention to accept such Offer, then such written
notice, taken in conjunction with the Offer Notice, shall constitute a valid
and legally binding agreement, and each of the Holders so giving such written
notice shall be entitled to sell to the Prospective Purchaser,
contemporaneously with the consummation of the Change of Control Transaction,
all of the Warrant Securities at the price specified therefor by such Holder in
accordance with this SECTION 19(D).  In the event that all of the Holders
reject or are deemed to have rejected the offer represented by the Offer
Notice, the Company or Graf, as applicable, shall be free to proceed to
consummate such Change of Control Transaction on the terms and conditions set
forth in the Offer Notice, provided that such sale is not otherwise prohibited
by any agreement between the Company and the Purchaser.  In the event the
Company or Graf, as applicable, fails to complete the proposed sale, transfer
or other disposition within ninety (90) days after the Holder or Holders
rejected or were deemed to have rejected the Offer, such shares of Stock shall
again be subject to the provisions of this SECTION 19(D).

                 The provisions of this SECTION 19(D) shall apply until the
termination of this Agreement pursuant to SECTION 24 to any Person who acquires
in any manner any Warrant Securities from any Holder.

                 (e)      LIMITATION ON PUT RIGHTS OF OTHERS.  The Company
covenants and agrees that, neither the Company nor any of its Subsidiaries
shall, directly or indirectly, grant to any Person or agree to or otherwise
become obligated in respect of any rights to require the Company or any of its
Subsidiaries to purchase securities of the Company upon the demand of any
Person.  The Company represents and warrants that neither it nor any of its
Subsidiaries has previously entered into any agreement granting any such rights
to any Person.

                 (f)      SEVERABILITY.  If any provision of this Agreement
shall be held or deemed to be, or shall in fact be, invalid, inoperative or
unenforceable as applied to any particular case in any jurisdiction or
jurisdictions, or in all jurisdictions or in 

                                     37

<PAGE>   41

all cases, because of the conflict of any provision with any constitution,
statute, rule or public policy, or for any other reason, such circumstances
shall not have the effect of rendering the provision or provisions in question,
invalid, inoperative or unenforceable in any other jurisdiction or in any other
case or circumstance or of rendering any other provision or provisions herein
contained invalid, inoperative or unenforceable to the extent that such other
provisions are not themselves actually in conflict with such constitution,
statute, rule or public policy, but this Agreement shall be reformed and
construed in any such jurisdiction or case as if such invalid, inoperative or
unenforceable provision had never been contained herein and such provision
reformed so that it would be valid, operative and enforceable to the maximum
extent permitted in such jurisdiction   or in such case.

                 (g)      REGISTRATION RIGHTS.  The Warrant Securities are
subject to and entitled to the benefit of certain registration rights, as more
fully set forth in the Registration Rights Agreement, which is incorporated
herein by reference.

                 SECTION 20.      NOTICES.  All notices, consents, approvals,
agreements and other communications provided hereunder shall be in writing or

Holders and the Company if addressed or delivered to them at the following

                 SECTION 22.      INDEMNIFICATION.  In consideration of the
transactions contemplated by this Agreement and the other Warrant Documents,
the Company hereby agrees to indemnify, exonerate and hold the Purchasers and
each Holder, each of their respective successors and assigns, each of the
respective officers, directors, employees, attorneys and agents of the
Purchasers and each Holder and each of their respective successors and assigns
(collectively, the "INDEMNIFIED PARTIES") free and harmless from and against
any and all actions, causes of action, suits, losses, costs, liabilities,
damages and expenses (irrespective of whether such Indemnified Party is a party
to the action for which indemnification hereunder is sought), including
attorneys' fees and disbursements (the "INDEMNIFIED LIABILITIES"), incurred by
the Indemnified Parties or any of them or asserted or awarded against the
Indemnified Parties or any of them as a result of, or arising out of, or
relating to:

                 (a)      the making of any claim by any investment banking
firm, broker or third party, claiming through the Company or as a result of the
relationship of such investment banking firm, broker or third party with the
Company, that it is entitled to compensation from any Indemnified Party in
connection with this Agreement or the transactions contemplated hereby;

                 (b)      any claim, investigation, litigation, or proceeding
made or commenced by a third party related to this Agreement or any other
Warrant Documents, whether or not the Indemnified Party or
any other Indemnified Party is party thereto;

                 (c)      the breach by the Company of any representation or
warranty set forth in this Agreement or in any other Warrant Document; or

                 (d)      the failure of the Company to comply with all terms,
conditions, and covenants set forth in this Agreement or in any other Warrant
Document;

EXCEPT FOR any such Indemnified Liabilities arising for the account 


                                     40

<PAGE>   44

of a particular Indemnified Party by reason of the relevant Indemnified Party's
gross negligence or wilful misconduct as determined by a final and
nonappealable decision of a court of competent jurisdiction.

                 If and to the extent that the foregoing undertaking may be
unenforceable for any reason, the Company hereby agrees to make the maximum
contribution to the payment and satisfaction of each of the Indemnified
Liabilities which is permissible under applicable law.  The foregoing indemnity
shall become effective immediately upon the execution and delivery hereof and
shall remain operative and in full force and effect notwithstanding the
consummation of the transactions contemplated hereunder, the issuance or
exercise of the Warrants hereunder, the termination of this Agreement pursuant
to SECTION 24, the invalidity or unenforceability of any term or provision of
this Agreement or any other Warrant Document, or any investigation made by or
on behalf of any Holder or any Purchaser.

                 SECTION 23.      SUCCESSORS.  All the covenants and provisions
of this Agreement by or for the benefit of the Company or the Holders shall
bind and inure to the benefit of their respective successors and assigns,
including those by operation of law, merger, consolidation or as otherwise
provided in SECTION 15(A).

                 SECTION 24.      TERMINATION.  Except as otherwise provided
herein, this Agreement shall terminate when all Warrants have expired
unexercised in accordance with their terms and no Warrant Securities are
outstanding.

                 SECTION 25.      GOVERNING LAW.  THIS AGREEMENT AND THE
WARRANTS SHALL BE GOVERNED BY THOSE PROVISIONS OF THE CORPORATE
CODE OF THE JURISDICTION IN WHICH THE COMPANY IS INCORPORATED AND ARTICLE 8 OF
THE UNIFORM COMMERCIAL CODE OF THE JURISDICTION IN WHICH THE COMPANY IS
INCORPORATED WHICH ARE NECESSARILY APPLICABLE TO SECURITIES ISSUED BY A
CORPORATION INCORPORATED IN SUCH JURISDICTION AND OTHERWISE SHALL BE DEEMED TO
BE A CONTRACT MADE UNDER THE LAWS OF THE STATE OF NEW YORK AND FOR ALL PURPOSES
SHALL BE CONSTRUED IN ACCORDANCE WITH THE INTERNAL LAWS OF SAID STATE.

                 SECTION 26.      BENEFITS OF THIS AGREEMENT.  Nothing in this
Agreement shall be construed to give to any Person other than the Company and
the Holders any legal or equitable right, remedy or  claim under this
Agreement; but this Agreement shall be for the sole and exclusive benefit of
the Company and the Holders.

                 SECTION 27.      COUNTERPARTS.  This Agreement may be executed
in any number of counterparts and each such counterpart shall for all purposes
be deemed to be an original, and all such counterparts shall together
constitute one and the same instrument.

                 SECTION 28.      AMENDMENTS; WAIVER.  No provision of this


                                     41


<PAGE>   45

Agreement may be amended or waived except by an instrument in writing signed by
the party sought to be bound; PROVIDED, HOWEVER, that any amendment requested
or waiver sought from the Holders of any provision of this Agreement which
affects Holders generally may be given by the Required Holders and any waiver
so given shall be binding on all Holders; PROVIDED FURTHER, that the provisions
of SECTION 11 with respect to the type of securities for which the Warrants are
exercisable may not be changed without the consent of each Holder affected
thereby.  No failure or delay by any party in exercising any right or remedy
hereunder shall operate as a waiver thereof, nor shall a waiver of a particular
right or remedy on one occasion be deemed a waiver of any other right or remedy
or a waiver of the same right or remedy on any subsequent occasion.

                 SECTION 29.      WAIVER OF JURY TRIAL.  EACH PURCHASER, EACH
HOLDER AND THE COMPANY HEREBY KNOWINGLY, VOLUNTARILY, AND INTENTIONALLY WAIVE
ANY RIGHTS THEY MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION BASED
HEREON, ON THE WARRANTS OR ON ANY OF THE OTHER WARRANT DOCUMENTS, OR ARISING
OUT OF, UNDER OR IN CONNECTION WITH, THIS AGREEMENT, THE WARRANTS OR ANY OF THE
OTHER WARRANT DOCUMENTS, OR ANY COURSE OF CONDUCT, COURSE OF DEALING,
STATEMENTS (WHETHER ORAL OR WRITTEN) OR ACTIONS OF THE PURCHASERS, ANY HOLDER
OR THE COMPANY.  THIS PROVISION IS A MATERIAL INDUCEMENT FOR THE PURCHASERS' 
ENTERING INTO THIS AGREEMENT.

                 SECTION 30.      JURISDICTION.  The Company hereby agrees that
any legal action or proceeding against it with respect to this Agreement, the
Warrants or any of the other Warrant Documents may be brought in the courts of
the State of New York or of the United States of America sitting in New York as
any Holder may elect, and, by execution and delivery hereof, for itself and in
respect of its property it accepts and consents to, generally and
unconditionally, the jurisdiction of the aforesaid courts and agrees that such
jurisdiction shall be exclusive, unless waived by the Required Holders in
writing,  with respect to any action or proceeding brought by it against such
Holders.  The Company hereby irrevocably designates, appoints and empowers CT
Corporation System whose present address is 1633 Broadway, New York, New York
10019, as its authorized agent to receive, for and on its behalf and its
property, service of process in the State of New York when and as legal actions
or proceedings may be brought in the courts of the State of New York or of the
United States of America sitting in New York, and such service of process shall
be deemed complete upon the date of delivery thereof to such agent, or upon
the earliest of any other date permitted by applicable law.  It is understood
that a copy of said process served on such agent will be forwarded to the
Company as soon as practicable, at its address set forth herein, but its
failure to receive such copy shall not affect in any way the service of said
process on said agent as the agent of the Company.  The Company irrevocably
consents to the service of process out of any of the aforementioned courts in
any such action or proceeding by the mailing of the copies thereof by certified

                                     42


<PAGE>   46

mail, return receipt requested, postage prepaid, to it at its address set forth
herein, such service to become effective upon the earlier of (i) the date 10
calendar days after such mailing and (ii) any earlier date permitted by
applicable law.  The Company agrees that it will at all times continuously
maintain an agent to receive service of process in the State of New York on
behalf of itself and its properties and in the event that, for any reason, the
agent named above or its successor shall no longer serve as its agent to
receive service of process in the State of New York on its behalf, it shall
promptly appoint a successor so to serve and shall advise the Holders thereof.
The Company agrees that Sections 5-1401 and 5-1402 of the General Obligations
Law of the State of New York shall apply to this Agreement and each of the
other Warrant Documents and waives any right to stay or to dismiss
any action or proceeding brought before said courts on the basis of FORUM NON
CONVENIENS.  Nothing herein shall affect the right of any Holder to bring
proceedings against the Company in the courts of any other jurisdiction or to
serve process in any other manner permitted by applicable law.

                 SECTION 31.      SPECIFIC PERFORMANCE.  The Company recognizes
that the rights of the Holders under this Agreement and the other Warrant
Documents are unique and, accordingly, the Holders shall, in addition to such
other remedies as may be available to any of them at law or in equity, have the
right to enforce their rights hereunder and thereunder by actions for
injunctive relief and specific performance to the extent permitted by law.  The
Company agrees that monetary damages would not be adequate compensation for any
loss incurred by reason of a breach by it of the provisions of this Agreement
or any of the other Warrant Documents and hereby agrees to waive in any action
for specific performance the defense that a remedy at law would be adequate.
This Agreement is not intended to limit or abridge any rights of the Holders
which may exist apart from this Agreement.

                 (a)      Each Holder shall treat any information concerning
the Company (whether prepared by the Company, its advisors or otherwise) which
has been or will be furnished by or on behalf of the Company or any Subsidiary
thereof (herein collectively referred to as the "CONFIDENTIAL INFORMATION") in
accordance with such Holder's customary procedures for handling confidential
information of this nature and will not wilfully disclose any Confidential
Information to any other party, except as otherwise provided herein.  The
Confidential Information will be used solely  in connection with the
transactions contemplated by the Warrant Documents or as otherwise authorized
by the Company.  The term "Confidential Information" shall not include, with
respect to any Holder, information which (i) is or becomes generally available
to the public other than as a result of a disclosure by such Holder, or its
affiliates, partners, directors, officers or employees, or 

                                     43

(ii) becomes available on a non-confidential basis from a source other than the
Company, any of its Subsidiaries, or their respective affiliates, partners,
directors, officers, employees or advisors, provided that such source is not
known by such Holder to be bound by a confidentiality agreement with or other
obligation of secrecy to the Company or any of its Subsidiaries.

                 (b)      Notwithstanding the foregoing, (i) Confidential
Information may be disclosed to the Holders' affiliates, partners, directors,
officers, employees and advisors who are in a confidential relationship with
such Person or who are informed of the confidential nature of such information,
(ii) Confidential Information may be disclosed as reasonably required by any
proposed transferee of Warrant Securities, provided that such proposed
transferee shall have agreed in writing for the Company's benefit to be bound
by the terms of this SECTION 32 and shall agree to return any Confidential
Information, and will not retain any copies, extracts or other reproductions in
whole or in part of such Confidential Information, if it does not become a
transferee of Warrant Securities, (iii) Confidential Information may be
disclosed to the extent requested or required by bank regulators or auditors or
any administrative body or commission to whose jurisdiction a Holder may be
subject, (iv) Confidential Information may be disclosed to the extent required
by law, regulation, subpoena, judicial order or legal process, provided that
notice of such requirement or order shall be promptly furnished to the Company
unless such notice is legally prohibited, (v) Confidential Information may be
disclosed to the extent required by the rules of any securities exchange on
which securities of any Holder are listed and traded, (vi) Confidential
Information may be disclosed in connection with the enforcement by any Holder
of its rights under the Warrant Documents or in connection with any litigation
between the Company and any Holder with resect to such Holder's Warrant
Securities or any Warrant Document, and (vii) Confidential Information may be
disclosed to the extent the Company consents to such disclosure.

                 SECTION 33.      ENTIRE AGREEMENT.  The parties hereto agree
that this Agreement, the Registration Rights Agreement, and the Loan Documents
constitute the entire agreement among the parties with respect to the subject
matter hereof and supersedes all prior agreements and understandings between
them as to such subject matter; and there are no restrictions, agreements,
arrangements, oral or written, between any or all of the parties relating to
the subject matter hereof which are not fully expressed or referred to herein
or therein.

                 IN WITNESS WHEREOF, the parties hereto have caused this
Agreement to be executed by their respective officers thereunto duly authorized
as of the day and year first above written.

                              Warrant Certificate

                          PHONETEL TECHNOLOGIES, INC.

                 This Warrant Certificate certifies that _________________, or
registered assigns, is the registered holder of the number of Warrants (the
"WARRANTS") set forth above to purchase shares of Series A Special Convertible
Preferred Stock, par value $.20 per share (the "SERIES A SPECIAL PREFERRED
STOCK"), of PHONETEL TECHNOLOGIES, INC., an Ohio corporation (the "COMPANY").
Each Warrant entitles the holder upon exercise to receive from the Company one
fully paid and nonassessable share of Series A Special Preferred Stock (a
"WARRANT SHARE") at the initial exercise price (the "EXERCISE PRICE") of $0.20,
payable in lawful money of the United States of America, upon surrender of this
Warrant Certificate and payment of the Exercise Price, if applicable, at the
office of the Company designated for such purpose, subject to the conditions
set forth herein and in the Warrant Agreement referenced below.  The Exercise
Price and number and type of Warrant Shares issuable upon exercise of the
Warrants are subject to adjustment upon the occurrence of certain events, as
set forth in the Warrant Agreement.

                 The Warrants evidenced by this Warrant Certificate are part of
a duly authorized issue of Warrants, and are issued or to be issued pursuant to
a Warrant Purchase Agreement dated as of March 15, 1996 (the "WARRANT
AGREEMENT"), duly executed and  




                                      A-1

delivered by the Company, ING and Cerberus, which Warrant Agreement is hereby
incorporated by reference in and made a part of this instrument and is hereby
referred to for a description of the rights, obligations and duties hereunder
of the Company and the holders of the Warrants (the words "holders" or "holder"
meaning the registered holders or registered holder).  A copy of the Warrant
Agreement may be obtained by the holder hereof upon written request to the
Company.

                 The holder of Warrants evidenced by this Warrant Certificate
may exercise such Warrants under and pursuant to the terms and conditions of
the Warrant Agreement by surrendering this Warrant Certificate, with the form
of election to purchase attached hereto (and by this reference made a part
hereof) properly completed and executed, together with payment of the Exercise
Price in cash at the office of the Company designated for such purpose.  In the
event that any exercise of Warrants evidenced hereby shall be for less than the
total number of Warrants evidenced hereby, there shall be issued by the Company
to the holder hereof or his or its registered assignee a new Warrant
Certificate evidencing the number of Warrants not exercised.

                 The Warrant Agreement provides that upon the occurrence of
certain events the Exercise Price set forth on the face hereof may, subject to
certain conditions, be adjusted.  If the Exercise Price is adjusted, the
Warrant Agreement provides that the number of shares of Warrant Shares issuable
upon the exercise of each Warrant shall be adjusted.  No fractional shares of
Warrant Shares will be issued upon the exercise of any Warrant, but the Company
will pay the cash value thereof determined as provided in the Warrant
Agreement.

                 The holder hereof possesses certain rights to require the
Company to purchase the Warrants (the "PUT RIGHTS"), and the holder hereof has
been granted certain rights to participate in a sale of the Common Stock of the
Company by certain shareholders of the Company (and certain of their successors
and assigns) all at the times specified in, and pursuant to the terms and
conditions set forth in, the Warrant Agreement.

                 The Holders of the Warrants are entitled to certain
registration rights as set forth in a Registration Rights Agreement dated as of
March 15, 1996, among the Company, ING and Cerberus (the "REGISTRATION RIGHTS
AGREEMENT").  By acceptance of this Warrant Certificate, the Holder hereof
agrees that upon exercise of any or all of the Warrants evidenced hereby, such
Holder will be bound by the Registration Rights Agreement.  A copy of the
Registration Rights Agreement may be obtained by the holder hereof upon written
request to the Company.


                 Warrant Certificates, when surrendered at the office of the
Company by the registered holder thereof in person or by  legal representative
or attorney duly authorized in writing, may be exchanged, in the manner and
subject to the limitations provided in the Warrant Agreement, for another
Warrant Certificate or Warrant Certificates of like tenor evidencing in the
aggregate a like number of Warrants.

                 The Company may deem and treat the registered holder(s)



                                      2

thereof as the absolute owner(s) of this Warrant Certificate (notwithstanding
any notation of ownership or other writing made hereon) for the purpose of any
exercise hereof, of any distribution to the holder(s) hereof and for all other
purposes, and the Company shall not be affected by any notice to the contrary.
Neither the Warrants nor this Warrant Certificate entitles any holder hereof to
any rights of a stockholder of the Company (other than the right to receive
dividends and distributions as set forth in SECTION 18 of the Warrant
Agreement).

                 IN WITNESS WHEREOF, the Company has caused this Warrant
Certificate to be signed by its duly authorized officer and has caused its
corporate seal to be affixed hereunto or imprinted hereon.

         SECTION 2.  REGISTRATION OF SECURITIES BY THE COMPANY.

                 (a)  PIGGYBACK REGISTRATION.  If at any time or from time to
time the Company shall propose to file on its behalf or on behalf of any of its
security holders a registration statement under the Securities Act on Form S-1,
S-2 or S-3 (or on any other form for the general registration of securities)
with respect to  any class of securities (other than a Shelf Registration
Statement filed pursuant to Section 3), the Company shall in each case:

                             (i)  promptly give written notice to each Holder
                 at least thirty (30) days before the anticipated filing date,
                 indicating the proposed offering price and describing the plan
                 of distribution;

                             (ii) include in such registration (and any related
                 qualification under blue sky or other state securities laws or
                 other compliance) and, at the request of any Holder, in any
                 underwriting involved therein, all the Registrable Securities
                 specified by any Holder or Holders of Registrable Securities
                 (the "SPECIFIED REGISTRABLE SECURITIES") in a written request
                 (the "REGISTRATION REQUEST") made within twenty (20) days
                 after receipt of such written notice from the Company; and

                            (iii) use its best efforts to cause the managing





                                       4
<PAGE>   8
                 underwriter(s) of such proposed underwritten offering to
                 permit the Specified Registrable Securities to be included in
                 the Registration Statement for such offering on the same terms
                 and conditions as any similar securities of the Company
                 included therein.

Notwithstanding the foregoing, if the managing underwriter(s) of such offering
advise(s) the Holders of Specified Registrable Securities in writing that
marketing considerations require a limitation on the securities, other than the
securities the Company intends to sell, to be included in any Registration
Statement filed under this Section 2 to a certain number of shares (the
"Available Securities"), then the Company shall in such case be obligated to
such Holders only with respect to such number of Available Securities.  Subject
to the registration rights of the holder of the Warrant to Purchase Common
Stock of the Company dated September 12, 1995 between PhoneTel and Gabriel
Capital, L.P., the holder of the Warrant to Purchase Common Stock of the
Company dated September 12, 1995 between PhoneTel and Ariel Fund, Ltd., the
former stockholders of World Communications, Inc. as beneficiaries of the
Registration Rights Agreement, dated September 22, 1995 (the "WORLD
REGISTRATION RIGHTS AGREEMENT"), and the former stockholders of Public
Telephone Corporation as beneficiaries of the Registration Rights Agreement
dated October 16, 1995 in each case as in effect on the date hereof, the
limitation on the number of Specified Registrable Securities will be imposed
pro rata (based upon the ratio of the number of shares of Specified Registrable
Securities which the managing underwriter(s) propose to include at the
anticipated initial public offering price to the number of Specified
Registrable  Securities owned by each Holder) among all Holders of Specified
Registrable Securities.

         Each Registration Request shall set forth the number or amount of
Specified Registrable Securities.  Notwithstanding any other provision of this
Agreement to the contrary, neither the delivery of the notice by the Company
nor of the Registration Request by any Holder shall in any way obligate the
Company to file a Registration Statement and, notwithstanding such filing, the
Company may, at any time prior to the effective date thereof, in its sole
discretion, determine not to offer the securities to which the Registration
Statement relates without liability to any of the Holders.  No registration of
Registrable Securities effected under this SECTION 2 shall relieve the Company
of its obligation to effect the registration of Registrable Securities pursuant
to SECTION 3.

                 (b)      PIGGYBACK REGISTRATION PROCEDURES.  If and when the
Company shall be required by the provisions of this SECTION 2 to effect the
registration of Registrable Securities under the Securities Act, the Company
will use its best efforts to effect such registration to permit the sale of
such Registrable Securities in accordance with the intended method or methods
of disposition thereof, and pursuant thereto it will, as expeditiously as





                                       5

possible:

                 (i)      before filing a Registration Statement or Prospectus
         or any amendments or supplements thereto, furnish to the Holders of
         the Registrable Securities covered by such Registration Statement and
         the underwriter(s), if any, copies of all such documents proposed to
         be filed, which documents will be made available, on a timely basis,
         for review by such Holders and underwriters;

                 (ii)     prepare and file with the SEC such amendments and
         post-effective amendments to any Registration Statement, and such
         supplements to the Prospectus, as may be reasonably requested by any
         Holder of Registrable Securities or the managing underwriter(s), if
         any, or as may be required by the Securities Act, the Exchange Act or
         by the rules, regulations or instructions applicable to the
         registration form utilized by the Company or as may otherwise be
         necessary to keep such Registration Statement effective until the
         earlier of such time as all of the Registrable Securities covered by
         such Registration Statement have been disposed of in accordance with
         the intended method of disposition set forth in such Registration
         Statement or Prospectus; and cause the Prospectus as so supplemented
         to be filed pursuant to Rule 424 (or any successor rule) under the
         Securities Act; and comply with the provisions of the Securities Act
         with respect to the disposition of all securities covered by such
         Registration Statement during the applicable period in accordance with
         the intended methods of disposition by the sellers thereof set forth
         in such Registration Statement or Prospectus;

                 (iii)    promptly notify the selling Holders of Registrable
         Securities and the managing underwriter(s), if any, and if requested
         by any such Person, confirm such advice in writing:

                          (a)     of the filing of the Prospectus or any
                 supplement to the Prospectus and of the effectiveness of the
                 Registration Statement and/or any post-effective amendment,

                          (b)     of any request by the SEC for amendments or
                 supplements to the Registration Statement or the Prospectus or
                 for additional information,

                          (c)     of the issuance by the SEC of any stop order
                 suspending the effectiveness of the Registration Statement or
                 the initiation of any proceedings for that purpose,

                          (d)     of the Company's becoming aware at any time 
                 that the representations and warranties of the Company





                                       6

                 contemplated by paragraph (xiv)(a) below have ceased to be
                 true and correct,

                 notification with respect to the suspension of the
                 qualification of the Registrable Securities for sale in any
                 jurisdiction or the initiation or threat of any proceeding for
                 such purpose, and

                          (f)     of the existence of any fact which, to the
                 knowledge of the Company, results in the Registration
                 Statement, the Prospectus or any document incorporated therein
                 by reference containing an untrue statement of material fact
                 or omitting to state a material fact required to be stated
                 therein or necessary to make the statements therein not
                 misleading;

                 (iv)     make every reasonable effort to obtain the withdrawal
         of any order suspending the effectiveness of the Registration

                 (v)      if reasonably requested by the managing
         underwriter(s) or the Required Holders of Registrable Securities being
         sold in connection with an underwritten  offering, immediately
         incorporate in a supplement to the Prospectus or post-effective
         amendment to the Registration Statement such information as the
         managing underwriter(s) or the Required Holders of the Registrable
         Securities being sold reasonably request to have included therein
         relating to the plan of distribution with respect to such Registrable
         Securities, including, without limitation, information with respect to
         the amount of Registrable Securities being sold to such underwriters,
         the purchase price being paid therefor by such underwriters and any
         other terms of the underwritten (or best-efforts underwritten)
         offering of the Registrable Securities to be sold in such offering;
         and make all required filings of such supplement to the Prospectus or

         Prospectus or post-effective amendment to the Registration Statement;

         Securities Act, as soon as practicable, but in no event later than
         thirty (30) days after the end of the 12 calendar month period
         commencing after the effective date of the Registration Statement;

                 (xvii)   cooperate and assist in any filings required to be

         Statement or the Prospectus, upon receipt of such confidentiality
         agreements as the Company may reasonably request, provide copies of

of outstanding Common Stock will execute and deliver an agreement undertaking
not to effect any public sale or distribution, including any sale pursuant to

after the effective date of a registration statement filed pursuant to this
SECTION 2.
         SECTION 3.  SHELF REGISTRATION.

                 (a)      FILING OF SHELF REGISTRATION STATEMENT. Promptly
after the date hereof and in any event on or before June 1, 1996, the Company
shall cause to be filed the Shelf Registration Statement providing for the sale
by the Holders of all of the Registrable Securities in accordance with the
terms hereof, and the Company will use its best efforts to cause such Shelf
Registration Statement to be declared effective by the SEC on or before June
30, 1996.  The Company agrees to use its best efforts to keep the Shelf
Registration Statement with respect to the Registrable Securities continuously
effective so long as any Holder holds Registrable Securities until such time as
each Holder has received an opinion of counsel to the Company (which opinion
and counsel shall be reasonably satisfactory to the Holder) to the effect that
each such Holder is permitted under Rule 144 to dispose of all of its
Registrable Securities within three months without such registration.  The
Company further agrees to amend the Shelf Registration Statement if and as
required by the rules, regulations or instructions applicable to the
registration form used by the Company for such Shelf Registration Statement or
by the Securities





                                       11

Act or any rules and regulations thereunder; PROVIDED, HOWEVER, that the
Company shall not be deemed to have used its best efforts to keep the Shelf
Registration Statement effective during the applicable period if it voluntarily
takes any action that would result in selling Holders not being able to sell
Registrable Securities covered thereby during that period, unless such action
is permitted by this Agreement or required under applicable law or the Company
has filed a post-effective amendment to the Shelf Registration Statement and
the SEC has not declared  it effective.  The Company may cause to be included
in the Shelf Registration Statement any securities of the Company held by
persons with registration rights under the agreements listed on SCHEDULE I to
the extent provided by such agreements and to permit such persons to exercise
any existing registration rights contained in the agreements listed on SCHEDULE
I.

                 (b)      SHELF REGISTRATION PROCEDURES.  In connection with
the obligations of the Company with respect to the Shelf Registration Statement
contemplated by this SECTION 3, the Company shall use its best efforts to
effect such registration to permit the sale of such Registrable Securities in
accordance with the intended method or methods of disposition thereof, and
pursuant thereto it will, as expeditiously as possible:

                 (i)      before filing a Shelf Registration Statement or Shelf
         Prospectus or any amendments or supplements thereto, furnish to the
         Holders of the Registrable Securities covered by such Shelf
         Registration Statement and the underwriter(s), if any, copies of all
         such documents proposed to be filed, which documents will be made
         available, on a timely basis, for review by such Holders and
         underwriters; and the Company will not file any Shelf Registration
         Statement or amendment thereto or any Shelf Prospectus or any
         supplement thereto to which the Required Holders of the Registrable
         Securities covered by such Shelf Registration Statement or the
         managing underwriter(s), if any, shall reasonably object;

                 (ii)     prepare and file with the SEC, within the time period
         set forth in SECTION 3(A) hereof, the Shelf Registration Statement,
         which Shelf Registration Statement (a) shall be available for the sale
         of the Registrable Securities in accordance with the intended method
         or methods of distribution by the selling Holders thereof and (b)
         shall comply as to form in all material respects with the requirements
         of the applicable form and include all financial statements required
         by the SEC to be filed therewith;

                 (iii) (a) prepare and file with the SEC such amendments to
         such Shelf Registration Statement as may be reasonably requested by
         any Holder of Registrable Securities or the managing underwriter(s),
         if any, or as may be required by the Securities Act, the Exchange Act
         or by the rules, regulations





                                       12

         or instructions applicable to the registration form utilized by the
         Company or as may otherwise be necessary to keep such Shelf
         Registration Statement effective for the applicable period; (b) cause
         the Shelf Prospectus to be amended or supplemented as may be
         reasonably requested by any Holder of Registrable Securities or the
         managing underwriter(s), if any, or as may be required by the
         Securities Act, the  Exchange Act or by the rules, regulations or
         instructions applicable to the registration form utilized by the
         Company or as may otherwise be necessary to keep such Shelf
         Registration Statement effective for the applicable period; (c) cause
         the Shelf Prospectus as so amended or supplemented to be filed
         pursuant to Rule 424 (or any successor rule) under the Securities Act;
         (d) respond as promptly as practicable to any comments received from
         the SEC with respect to the Shelf Registration Statement or any
         amendment thereto; and (e) comply with the provisions of the
         Securities Act with respect to the disposition of all securities
         covered by such Shelf Registration Statement during the applicable
         period in accordance with the intended method or methods of
         distribution by the selling Holders thereof;

                 (iv)     promptly notify the selling Holders of Registrable
         Securities and the managing underwriter(s), if any, and if requested
         by any such Person, confirm such advice in writing:

                          (a)     of the filing of the Shelf Prospectus or any
                 supplement to the Shelf Prospectus and of the effectiveness of
                 the Shelf Registration Statement and/or any post-effective
                 amendment,

                          (b)     of any request by the SEC for amendments or
                 supplements to the Shelf Registration Statement or the Shelf
                 Prospectus or for additional information,

                          (c)     of the issuance by the SEC of any stop order

                 purpose,

                          (d)     of the Company's becoming aware at any time
                 that the representations and warranties of the Company
                 contemplated by paragraph (xv)(a) below have ceased to be true
                 and correct,

                          (e)     of the receipt by the Company of any
                 notification with respect to the suspension of the
                 qualification of the Registrable Securities for sale in any
                 jurisdiction or the initiation or threat of any proceeding for
                 such purpose, and

                          (f)     of the existence of any fact which, to the

                 knowledge of the Company, results in the Shelf Registration
                 Statement, the Shelf Prospectus or any document incorporated
                 therein by reference containing an untrue statement of
                 material fact or omitting to state a material fact required to

                 underwriters shall reasonably request) with respect to all
                 parties to be indemnified pursuant to said SECTION 6; and

                          (e)     deliver such documents and certificates as
                 may reasonably be requested by the Required Holders of the
                 Registrable Securities being sold, or the managing
                 underwriter(s), if any, to evidence compliance with this
                 paragraph (xiv) and with any customary conditions contained in
                 the underwriting agreement or other agreement entered into by
                 the Company;

         the foregoing to be done upon each closing under any underwriting or
         similar agreement as and to the extent required thereunder and from
         time to time as may reasonably be requested by any selling Holder of
         Registrable Securities in connection with the disposition of
         Registrable Securities pursuant to such Shelf Registration Statement,
         all in a manner consistent with customary industry practice;

                 (xvi)    upon execution and delivery of such confidentiality
         agreements as the Company may reasonably request, make available to
         the Holders of the Registrable Securities being sold, any underwriter
         participating in any disposition pursuant to such Shelf Registration
         Statement, and any attorney or accountant retained by such Holders or
         underwriter, all financial and other records, pertinent corporate
         documents and properties of the Company, and cause the Company's
         officers, directors and employees to supply all information reasonably
         requested by any such Holder, underwriter, attorney or accountant in
         connection with the registration, at such time or times as the Person
         requesting such information shall reasonably determine;

                 (xvii)   otherwise use its best efforts to comply with the
         Securities Act, the Exchange Act, all applicable rules and regulations
         of the SEC and all applicable state blue sky and other securities
         laws, rules and regulations, and make generally available to its
         security holders, as soon as practicable, an earnings statement
         satisfying the provisions of Section 11(a) of the Securities Act;

                 (xviii)  cooperate and assist in any filings required to be
         made with the NASD and in the performance of any due diligence
         investigation by any underwriter (including any "qualified independent
         underwriter" that is required to be retained in accordance with the
         rules and regulations of the NASD); and





                                       17
<PAGE>   21
                 (xix)    prior to the filing of any document which is being
         prepared for incorporation by reference into the Registration
         Statement or the Prospectus, upon receipt of such confidentiality
         agreements as the Company may reasonably request, provide copies of
         such document to counsel to the selling Holders of Registrable
         Securities, and to the managing underwriter(s), if any, and make the
         Company's representatives available for discussion of such document.

                 (c)      COVENANTS OF HOLDERS.  In connection with and as a
condition to the Company's obligations with respect to the Shelf Registration
Statement pursuant to this SECTION 3, each Holder covenants and agrees that (i)
upon receipt of any notice from the Company contemplated by Section 3(b)(iv)
(in respect of the occurrence of an event contemplated by clause (f) of Section
3(b)(iv)), such Holder shall not offer or sell any Registrable Securities
pursuant to the Shelf Registration Statement until such Holder receives copies
of the supplemented or amended Shelf Prospectus contemplated by Section
3(b)(xii) hereof and receives notice that any post-effective amendment has
become effective, and, if so directed by the Company, such Holder will deliver
to the Company (at the expense of the Company) all copies in its possession,
other than permanent file copies then in such Holder's possession, of the Shelf
Prospectus as amended or supplemented at the time of receipt of such notice;
(ii) such Holder and any of its officers, directors or affiliates, if any, will
comply with the provisions of Rule 10b-6 and 10b-7 under the Exchange Act as
applicable to them in connection with sales of Registrable Securities pursuant
to the Shelf Registration Statement; and (iii) such Holder and any of its
officers, directors or affiliates, if any, will comply with the prospectus
delivery requirements of the Securities Act as applicable to them in connection
with sales of Registrable Securities pursuant to the Shelf Registration
Statement.

                 (d)  MECHANICS OF SHELF REGISTRATION.  Each registration
effected pursuant to this SECTION 3 shall be effected by the filing of a Shelf
Registration Statement on Form S-1 or Form S-3 (provided that if Form S-3 is
used the Shelf Prospectus shall contain the information that would have been
required to be included therein had Form S-1 been used), unless the use of a
different form has been agreed upon in writing by the Required Holders;
PROVIDED, HOWEVER, that if the intended method of disposition by the requesting
Holders is to be an underwritten  offering, the Company shall use such form of
Registration Statement as is acceptable to the underwriter(s).  Whenever a
registration requested by one or more Holders pursuant to this SECTION 3 is for
an underwritten offering, only Registrable Securities which are to be
distributed by the underwriters may be included in such registration, without
the written consent of the Required Holders.

                 (e)  BLACKOUT PERIOD.  The Company shall be entitled to





                                       18
<PAGE>   22
(i) postpone for not more than 45 days the filing of the Shelf Registration
Statement otherwise required to be prepared and filed by the Company pursuant
to SECTION 3, or (ii) elect that the Shelf Registration Statement not be
usable, for a reasonable period of time, but not in excess of 45 days (a
"Blackout Period"), if the Company determines in good faith that the
registration and distribution of Registrable Securities (or the use of the
Shelf Registration Statement or related Shelf Prospectus) would interfere with
any pending material financing, acquisition or corporate reorganization or
similar transaction involving the Company or any of its subsidiaries because it
would require premature disclosure thereof and promptly gives the Holders of
Registrable Securities written notice of such determination, containing a
general statement of the reasons for such postponement or restriction on use
and an approximation of the anticipated delay; PROVIDED, HOWEVER, that the
aggregate number of days included in all Blackout Periods during any
consecutive 12 months shall not exceed 90 days.

                 (f)      HOLDBACK AGREEMENT.  Subject to the provisions of
this sentence becoming effective in accordance with the immediately following
sentence, if (i) the Company shall file a registration statement (other than in
connection with the registration of securities issuable pursuant to an employee
stock option, stock purchase or similar plan or pursuant to a merger, exchange
offer or a transaction of the type specified in Rule 145(a) under the
Securities Act) with respect to its Common Stock and (ii) with reasonable prior
notice, the managing underwriter or underwriters advises the Company in writing
(in which case the Company shall notify the Holders) that a public sale or
distribution of Registrable Securities would adversely impact such offering,
then each Holder of Registrable Securities shall, to the extent not
inconsistent with applicable law, refrain from effecting any public sale or
distribution of Registrable Securities during the 10-day period prior to, and
during the 90-day period beginning on, the effective date of such registration
statement.  The provisions set forth in the preceding sentence shall not become
effective until the Company shall have entered into agreements with the holders
of at least two-thirds of the shares entitled to registration rights pursuant
to the World Registration Rights Agreement providing that (i) such holders
agree to waive any priority to which they are entitled over the  Holders in
connection with the exercise of incidental or piggyback registration rights and
instead agree that in connection with any reductions in the shares entitled to
participate in an underwritten offering such holders under the World
Registration Rights Agreement, the Holders and any other holders entitled to an
equal priority with the Holders will bear such reductions on a pro rata basis
based on the number of shares held by each such Person, and (ii) such holders
agree to a holdback agreement on terms no less favorable to the Company than
set forth in the preceding sentence.

<PAGE>   23
                 (a)      All expenses incident to the Company's performance of
or compliance with its obligations under this Agreement (excluding underwriting
discounts, selling commissions and brokerage fees, which will be paid by the
selling Holders) will be paid by the Company, regardless of whether Registrable
Securities are sold pursuant to any Registration Statement or Shelf
Registration Statement, including, without limitation:

                 (i)         all registration, filing and listing fees;

                 (ii)        fees and expenses of compliance with securities or
         blue sky laws (including, without limitation, the fees and
         disbursements of counsel for the underwriters, if any, or selling
         Holders in connection with blue sky and state securities
         qualifications of Registrable Securities and determination of their
         eligibility for investment under the laws of such jurisdictions as the
         managing underwriter(s), if any, or the Required Holders of the
         Registrable Securities covered by such Registration Statement or Shelf
         Registration Statement may reasonably designate);

                 (iii)       printing (including, without limitation, expenses
         of printing or engraving certificates for the Registrable Securities
         in a form eligible for deposit with Depository Trust Company and of
         printing prospectuses), messenger, telephone and delivery expenses;

                 (iv)        fees and disbursements of counsel for the Company
         and, subject to SECTION 4(B), counsel for the selling Holders of the
         Registrable Securities;

                 (v)         fees and disbursements of all independent
         certified public accountants of the Company (including, without
         limitation, the expenses of any special audit and, in connection with
         any underwritten offering, "cold  comfort" letters required by or
         incident to such performance);

                 (vi)        Securities Act liability insurance if the Company
         so desires or if the managing underwriters, if any, so require(s);

                 (vii)       fees and expenses of other Persons (including
         special experts) retained by the Company; and

                 (viii)      fees and expenses associated with any NASD filing
         required to be made in connection with any Registration Statement or
         Shelf Registration Statement, including, if applicable, the fees and
         expenses of any "qualified independent underwriter" (and its counsel)





                                       20
<PAGE>   24
         that is required to be retained in accordance with the rules and
         regulations of the NASD.

         The Company will, in any event, pay its internal expenses (including,
without limitation, all salaries and expenses of its officers and employees
performing legal or accounting duties), the expense of any annual audit, the
fees and expenses incurred in connection with the listing of the securities to
be registered on each securities exchange on which securities of the same class
are then listed or the qualification for trading of the securities to be
registered in each inter-dealer quotation system in which securities of the
same class are then traded, and rating agency fees.

                 (b)      In connection with each Registration Statement or
Shelf Registration Statement required hereunder, the Company will reimburse the
Holders of Registrable Securities being registered pursuant to such
Registration Statement or Shelf Registration Statement for the reasonable fees
and disbursements of not more than one counsel chosen by the Required Holders
of the Registrable Securities being sold; the expense of any additional counsel
for the Holders shall be paid by the Holders.

                 (c)      The term "REGISTRATION EXPENSES" shall mean the
expenses payable by the Company pursuant to the provisions of this SECTION 4.

         SECTION 5.  CONDITIONS TO REGISTRATION.

         Each Holder's right to have Registrable Securities included in any
Registration Statement or Shelf Registration Statement filed by the Company in
accordance with the provisions of SECTION 2 or SECTION 3 shall be subject to
the following conditions:

                 (a)      The Holders on whose behalf such Registrable
Securities are to be included shall be required to furnish the Company in a
timely manner with all information required by the applicable rules and
regulations of the SEC concerning the proposed method of sale or other
disposition of such securities, the identity of and compensation to be paid to
any proposed underwriters to be employed in connection therewith, and such
other information as may be reasonably required by the Company properly to
prepare and file such Registration Statement or Shelf Registration Statement in
accordance with applicable provisions of the Securities Act;

                 (b)      If any such Holder desires to sell and distribute
Registrable Securities over a period of time, or from time to time, at then
prevailing market prices, then any such Holder shall execute and deliver to the
Company such written undertakings as the Company and its counsel may reasonably
require in order to assure full compliance with relevant provisions of the
Securities Act and





                                       21
<PAGE>   25
the Exchange Act;

                 (c)      In the case of any registration requested pursuant to
the provisions of SECTION 2, the offering price for any Registrable Securities
to be so registered shall be no less than for any securities of the same class
then to be registered for sale for the account of the Company or other security
holders, unless such Registrable Securities are to be offered from time to time
based on the prevailing market price;

                 (d)      Upon receipt of any notice from the Company of the
happening of any event of the kind described in paragraph (xi) of SECTION 2(B)
or paragraph (xii) of SECTION 3(B), such Holder will forthwith discontinue
disposition of Registrable Securities until such Holder's receipt of the copies
of the supplemented Prospectus contemplated by such paragraph, or until it is
advised in writing by the Company that the use of the Prospectus may be
resumed, and has received copies of any additional or supplemental filings
which are incorporated by reference in the Prospectus, and, if so directed by
the Company, such Holder will deliver to the Company (at the Company's expense)
all copies, other than permanent file copies then in such Holder's possession,
of the Prospectus covering such Registrable Securities current at the time of
receipt of such notice; and

                 (e)      In the case of any underwritten offering on behalf of
the Holders of Registrable Securities, such Holders will enter into such
agreements (including underwriting agreements and lock-up agreements) as the
managing underwriters shall reasonably request and as are customary in similar
circumstances.

         SECTION 6.       INDEMNIFICATION.

                 (a)      INDEMNIFICATION BY THE COMPANY.  In the event of the
registration of any Registrable Securities under the  Securities Act pursuant
to the provisions hereof, the Company will indemnify and hold harmless the
seller of such Registrable Securities, its partners, directors, officers,
employees and agents, each underwriter, broker and dealer, if any, who
participates in the offering or sale of such securities, and each other Person,
if any, who controls such seller or any such underwriter, broker or dealer
within the meaning of either Section 15 of the Securities Act or Section 20 of
the Exchange Act (each such Person being hereinafter sometimes referred to as
an "INDEMNIFIED PERSON", provided that for purposes of clauses (b), (c) and (d)
of this SECTION 6 "Indemnified Person" shall include the Company, its partners,
directors, officers, employees and agents, and each other Person, if any who
controls the Company within the meaning of either Section 15 of the Securities
Act or Section 20 of the Exchange Act) from and against any losses, claims,
damages, liabilities or expenses, joint or several, to which such indemnified
Person may become subject under the Securities Act, the Exchange Act or
otherwise, insofar as such





                                       22
<PAGE>   26
losses, claims, damages, liabilities or expenses (or actions in respect
thereof) arise out of or are based upon any untrue statement or alleged untrue
statement of any material fact contained or incorporated by reference in any
Registration Statement, Shelf Registration Statement, Prospectus or Shelf
Prospectus or any amendment or supplement thereto, or any document incorporated
by reference therein, or arise out of or are based upon the omission or alleged
omission to state therein a material fact required to be stated therein or
necessary to make the statements therein not misleading, and will reimburse
each such Indemnified Person for any legal or other expenses reasonably
incurred by such Indemnified Person in connection with investigating or
defending any such loss, claim, damage, liability or action; PROVIDED, HOWEVER,
that the Company will not be liable in any such case to the extent that any
such loss, claim, damage or liability (i) arises out of or is based upon an
untrue statement or alleged untrue statement or omission or alleged omission
made or incorporated by reference in the Registration Statement, Shelf
Registration Statement, Prospectus or Shelf Prospectus or any amendment or
supplement thereto, in reliance upon and in conformity with written information
furnished to the Company by such Indemnified Person for use in preparation
thereof or (ii) arises out of the use of any Prospectus or Shelf Prospectus  by
an Indemnified Party after the Company has provided such Indemnified Party with
the notice and supplement referred to in SECTION 2(B)(XI) or SECTION 3(B)(XII)
if such Prospectus or Shelf Prospectus is the subject of such notice.  Such
indemnity shall remain in full force and effect regardless of any investigation
made by or on behalf of such Indemnified Person and shall survive the transfer
of such Registrable Securities by such seller.

                 (b)      INDEMNIFICATION BY HOLDERS OF REGISTRABLE SECURITIES.
In the event of the registration of any Registrable Securities under the
Securities Act pursuant to the provisions hereof, each Holder on whose behalf
such Registrable Securities shall have been registered will indemnify and hold
harmless each and every Indemnified Person against any losses, claims, damages
or liabilities, joint or several, to which such Indemnified Person may become
subject under the Securities Act, the Exchange Act or otherwise, insofar as
such losses, claims, damages, liabilities or expenses (or actions in respect
thereof) arise out of or are based upon any untrue statement or alleged untrue
statement of a material fact contained or incorporated by reference in any
Registration Statement, Shelf Registration Statement, Prospectus or Shelf
Prospectus or any amendment or supplement thereto or any document incorporated
by reference therein, or arise out of or are based upon the omission or alleged
omission to state therein a material fact required to be stated therein or
necessary to make the statements therein not misleading, which untrue statement
or alleged untrue statement or omission or alleged omission has been made or
incorporated therein in reliance upon and in conformity with written
information furnished to the Company by such Holder





                                       23
<PAGE>   27
specifically stating that it is for use in preparation thereof, and will
reimburse each such Indemnified Person for any legal and other expenses
reasonably incurred by such Indemnified Person in connection with investigating
or defending any such loss, claim, damage, liability or action; PROVIDED,
HOWEVER, that the liability of each Holder hereunder shall be limited to the
proceeds received by such Holder from the sale of Registrable Securities
covered by such Registration Statement or Shelf Registration Statement.

                 (c)      PROCEDURE.  Promptly after receipt by an Indemnified
Person of notice of the commencement of any action (including any governmental
investigation or inquiry), such Indemnified Person will, if such Indemnified
Person intends to make a claim in respect thereof against the party agreeing to
indemnify such Indemnified Person pursuant to paragraphs (a) or (b) hereof
(each such Person being hereinafter referred to as an "INDEMNIFYING PERSON"),
give written notice to such Indemnifying Person of the commencement thereof,
but the omission so to notify the Indemnifying Person shall not relieve the
Indemnifying Person from any of its obligations pursuant to the provisions of
this SECTION 6 except to the extent that the Indemnifying Person is actually
prejudiced by such failure to give notice.  In case any such action is brought
against any Indemnified Person and it notifies an Indemnifying Person of the
commencement thereof, the Indemnifying Person shall be entitled to participate
in, and to the extent that it may wish, jointly with any other Indemnifying
Person similarly notified, to assume the defense thereof, with counsel
reasonably satisfactory to such Indemnified Person, and after notice from the
Indemnifying Person to such Indemnified Person, the Indemnifying Person shall
not, except as hereinafter  provided, be responsible for any legal or other
expenses subsequently incurred by such Indemnified Person in connection with
the defense thereof.  No Indemnifying Person will consent to entry of any
judgment or enter into any settlement which does not include as an
unconditional term thereof the giving by the claimant or plaintiff to such
Indemnified Person of a release from all liability in respect of such claim or
litigation.

         Such Indemnified Person shall have the right to employ separate
counsel in any such action and to participate in the defense thereof, but the
fees and expenses of such counsel shall be the expense of such Indemnified
Person unless (a) the Indemnifying Person has agreed to pay such fees and
expenses or (b) the Indemnifying Person shall have failed to assume the defense
of such action or proceeding or has failed to employ counsel reasonably
satisfactory to such Indemnified Person in any such action or proceeding or (c)
the named parties to any such action or proceeding (including any impleaded
parties) include both such Indemnified Person and the Indemnifying Person and
such Indemnified Person shall have been advised by counsel that representation
of both parties by the same counsel would be inappropriate due to actual or
potential material differing interests between them (in which case, if such
Indemnified Person notifies the Indemnifying





                                       24
<PAGE>   28
Person in writing that it elects to employ separate counsel at the expense of
the Indemnifying Person, the Indemnifying Person shall not have the right to
assume the defense of such action or proceeding on behalf of such Indemnified
Person).  The Indemnifying Person shall not be liable for any settlement of any
such action or proceeding effected without its written consent, which consent
shall not unreasonably be withheld, delayed or conditioned, but if settled with
its written consent, or if there is a final judgment for the plaintiff in any
such action or proceeding, the Company agrees to indemnify and hold harmless
such Indemnified Persons from and against any loss or liability by reason of
such settlement or judgment.

                 (d)      CONTRIBUTION.  If the indemnification provided for in
this SECTION 6 is unavailable to a party that would have been an Indemnified
Person under this SECTION 6 in respect of any losses, claims, damages,
liabilities or expenses (or actions in respect thereof) referred to herein,
then each party that would have been an Indemnifying Person thereunder shall,
in lieu of indemnifying such Indemnified Person, contribute to the amount paid
or payable by such Indemnified Person as a result of such losses, claims,
damages, liabilities or expenses (or actions in respect thereof) in such
proportion as is appropriate to reflect the relative fault of the Indemnifying
Person on the one hand and the Indemnified Person on the other in connection
with the statement or omission which resulted in such losses, claims, damages,
liabilities or expenses (or actions in respect thereof), as well as any other
relevant equitable considerations.  The  relative fault shall be determined by
reference to, among other things, whether the untrue or alleged untrue
statement of a material fact or the omission or alleged omission of a material
fact relates to information supplied by the Indemnifying Person or the
Indemnified Person and the parties' relative intent, knowledge, access to
information and opportunity to correct or prevent such statement or omission.
The amount paid or payable by a party as a result of the losses, claims,
damages, liabilities and expenses referred to above shall be deemed to include,
subject to the limitations set forth in SECTION 6(C), any legal or other fees
or expenses reasonably incurred by such party in connection with the
investigation or defense of any action or claim.  The Company and each Holder
of Registrable Securities agrees that it would not be just and equitable if
contribution pursuant to this SECTION 6 were determined by PRO RATA allocation
or by any other method of allocation which does not take account of the
equitable considerations referred to in this SECTION 6.  Notwithstanding the
provisions of this SECTION 6(D), no Holder of Registrable Securities shall be
required to contribute any amount in excess of the amount by which the total
price at which the Registrable Securities sold by it exceeds the amount of any
damages which such Holder has otherwise been required to pay by reason of such
untrue or alleged untrue statement or omission or alleged omission.





                                       25
<PAGE>   29
         No Person guilty of fraudulent misrepresentation (within the meaning
of Section 11(f) of the Securities Act) shall be entitled to contribution from
any Person who was not guilty of such fraudulent misrepresentation.

         Indemnification or, if appropriate, contribution, similar to that
specified in the preceding provisions of this SECTION 6 (with appropriate
modifications) shall be given by the Company and each seller of Registrable
Securities with respect to any required registration or other qualification of
such securities under any federal or state law or regulation or governmental
authority other than the Securities Act.

         In the event of any underwritten offering of Registrable Securities
under the Securities Act pursuant to the provisions of SECTION 2 or SECTION 3,
the Company and each Holder on whose behalf such Registrable Securities shall
have been registered agree to enter into an underwriting agreement, in standard
form, with the underwriters, which underwriting agreement may contain
additional provisions with respect to indemnification and contribution in lieu
thereof.

         SECTION 7.  EXCHANGE ACT REGISTRATION; RULE 144 REPORTING.

         The Company covenants and agrees that until such time as the Holders
no longer hold any Registrable Securities it will:

                 (a)      if required by law, maintain an effective
registration statement (containing such information and documents as the SEC
shall specify) with respect to the Common Stock of the Company under Section
12(g) of the Exchange Act;

                 (b)      make and keep public information available, as those
terms are understood and defined in Rule 144 under the Securities Act, at all
times after the effective date that the Company becomes subject to the
reporting requirements of the Securities Act or the Exchange Act (even if the
Company subsequently ceases to be subject to such reporting requirements);

                 (c)      file with the SEC in a timely manner all reports and
documents required of the Company under the Securities Act and the Exchange
Act;

                 (d)      furnish to any Holder promptly upon request (i) a
written statement by the Company as to its compliance with the reporting
requirements of Rule 144 (and any similar or successor rules) and of the
Securities Act and the Exchange Act, (ii) a copy of the most recent annual or
quarterly report of the Company (beginning after the Company becomes subject to
such reporting requirements), and (iii) such other reports and documents of the
Company and other information in the possession of or reasonably attainable by
the Company as such Holder may reasonably request in





                                       26
<PAGE>   30
availing itself of any rule or regulation of the SEC allowing such Holder to
sell any such securities without registration; and

                 (e)      take such further action as any Holder of Registrable
Securities may from time to time reasonably request to enable such Holder to
sell Registrable Securities without registration under the Securities Act
within the limitation of the exemptions provided by (i) Rule 144 under the
Securities Act, as such rule may be amended from time to time, or (ii) any
similar rule or regulation hereafter adopted by the SEC.

         The Company represents and warrants that such registration statement
or any information, document or report filed with the SEC in connection
therewith or any information so made public shall not contain any untrue
statement of a material fact or omit to state a material fact required to be
stated therein or necessary in order to make the statements contained therein
not misleading.  The Company agrees to indemnify and hold harmless (or to the
extent the same is not enforceable, make contribution to) the Holders, their
partners, officers, directors, employees and agents, each broker, dealer or
underwriter (within the meaning of the Securities Act) acting for any Holder in
connection with any offering or sale by such Holder of Registrable Securities
or any Person controlling (within the meaning of either Section 15 of the
Securities Act or Section 20 of the Exchange Act) such Holder and any such
broker, dealer or underwriter from and against any and all losses, claims,
damages, liabilities or expenses (or actions in respect thereof) arising out of
or resulting from any breach of the foregoing representation or warranty, all
on terms and conditions comparable to those set forth in SECTION 6.

         SECTION 8.  LIMITATION ON REGISTRATION RIGHTS OF OTHERS.

         The Company represents and warrants that, except as set forth on
SCHEDULE I to this Agreement, it has not granted to any Person the right to
request or require the Company to register any securities issued by the
Company.  The Company covenants and agrees that after the date hereof, so long
as any Holder holds any Warrant Securities, Term Notes, Series B Special
Preferred Stock or Common Stock issuable upon conversion of Series B Special
Preferred Stock, the Company will not, directly or indirectly, grant to any
Person (except as provided in Section 3(a) hereof) or agree to or otherwise
become obligated in respect of (a) any registration rights of securities of the
Company upon the demand of any Person (including any shelf registration)
without the prior written consent of the Required Holders; or (b) rights of
registration in the nature or substantially in the nature of those set forth in
SECTION 2 unless such rights are expressly subject and subordinated to the
rights of registration of the Holders pursuant to SECTION 2 hereof on terms
reasonably satisfactory to the Required Holders.

         SECTION 9.  MERGERS, ETC.





                                       27
<PAGE>   31
         In addition to any other restrictions on mergers, consolidations and
reorganizations contained in the Credit Agreement, the Warrant Agreement or in
the certificate of incorporation, by-laws or agreements of the Company, the
Company covenants and agrees that it shall not, directly or indirectly, enter
into any merger, consolidation or reorganization in which the Company shall not
be the surviving corporation and in which the Holders shall not have had the
right to receive cash for all their Registrable Securities, unless the
surviving corporation shall, prior to such merger, consolidation or
reorganization, agree in a writing satisfactory in form, scope and substance to
the Required Holders to assume the obligations of the Company under this
Agreement, and for such purpose references hereunder to "Registrable
Securities" shall be deemed to include the securities which such Holders would
be entitled to receive in exchange for Registrable Securities pursuant to any
such merger, consolidation or reorganization.

         If, and as often as, there are any changes in the Registrable
Securities by way of stock split, stock dividend, combination or
classification, or through merger, consolidation, reorganization or
recapitalization, or by any other means, appropriate adjustments shall be made
in the provisions hereof as may be  required, so that the rights and privileges
granted hereby shall continue with respect to the Registrable Securities as so
changed.

         SECTION 10.  NOTICES, ETC.

         All notices, consents, approvals, agreements and other communications
provided hereunder shall be in writing or by telex or telecopy and shall be

         SECTION 11.  ENTIRE AGREEMENT.

         The parties hereto agree that this Agreement and the agreements
specifically referred to in Section 33 of the Warrant Agreement constitute the
entire agreement among the parties with respect to the subject matter hereof
and supersedes all prior





                                       29
<PAGE>   33
agreements and understandings between them as to such subject matter; and there
are no restrictions, agreements, arrangements, oral or written, between any or
all of the parties relating to the subject matter hereof which are not fully
expressed or referred to herein or therein.

         SECTION 12.  WAIVERS AND FURTHER AGREEMENTS.

         Any waiver of any terms or conditions of this Agreement shall not
operate as a waiver of any other breach of such terms or conditions or any
other term or condition, nor shall any failure to enforce any provision hereof
operate as a waiver of such provision or of any other provision hereof;
PROVIDED, HOWEVER, that no such written waiver unless it by its own terms
explicitly provides to the contrary, shall be construed to effect a continuing
waiver of the provision being waived and no such waiver in any instance shall
constitute a waiver in any other instance or for any other purpose or impair
the right of the party against whom such waiver is claimed in all other
instances or for all other purposes to require full compliance with such
provision.  Each of the parties hereto agrees to execute all such further
instruments and documents and to take all such further action as the other
parties may reasonably require in order to effectuate the terms and purposes of
this Agreement.

         SECTION 13.  AMENDMENTS.

         This Agreement may not be amended nor shall any waiver, change,
modification, consent or discharge be effected except by an instrument in
writing executed by or on behalf of the party or parties against whom
enforcement of any amendment, waiver, change, modification, consent or
discharge is sought; PROVIDED, HOWEVER, that any waiver sought from the Holders
of any provision of this Agreement which affects the Holders generally, and any
action required to be taken by the Holders as a group pursuant to this
Agreement, shall be given or taken by the Required Holders, and any such waiver
or action so given or taken shall be binding on all Holders.  No failure or
delay by any party in exercising any right or remedy hereunder shall operate as
a waiver thereof, and a waiver of a particular right or remedy on one occasion
shall not be deemed a waiver of any other right or remedy or a waiver of the
same right or remedy on any subsequent occasion.

         SECTION 14.  ASSIGNMENT; SUCCESSORS AND ASSIGNS.

         This Agreement shall be binding upon and shall inure to the benefit of
the parties hereto and their respective heirs, executors, legal
representatives, successors and permitted assigns, including, without
limitation, any Holders, from time to time of the Registrable Securities.
Anything in this Agreement to the contrary notwithstanding, the term "Holders"
as used in this Agreement shall be deemed to include the registered Holders
from





                                       30
<PAGE>   34
time to time of the Warrant Securities, the Term Notes, the Series B Special
Preferred Stock and Common Stock issuable upon conversion of the Series B
Special Preferred Stock.

         SECTION 15.  SEVERABILITY.

         If any provision of this Agreement shall be held or deemed to be, or
shall in fact be, invalid, inoperative or unenforceable as applied to any
particular case in any jurisdiction or jurisdictions, or in all jurisdictions
or in all cases, because any provision conflicts with any constitution,
statute, rule or public policy, or for any other reason, such circumstance
shall not have the effect of rendering the provision or provisions in question,
invalid, inoperative or unenforceable in any other jurisdiction or in any other
case or circumstance or of rendering any other provision or provisions herein
contained invalid, inoperative or unenforceable to the extent that such other
provisions are not themselves actually in conflict with such constitution,
statute, rule or public policy, but this Agreement shall be reformed and
construed in any such jurisdiction or case  as if such invalid, inoperative or
unenforceable provision had never been contained herein and such provision
reformed so that it would be valid, operative and enforceable to the maximum
extent permitted in such jurisdiction or in such case.

         SECTION 16.  COUNTERPARTS.

         This Agreement may be executed in two or more counterparts (each of
which need not be executed by each of the parties), each of which shall be
deemed an original, but all of which together shall constitute one and the same
instrument, and in pleading or proving any provision of this Agreement, it
shall not be necessary to produce more than one such counterpart.

         SECTION 17.  SECTION HEADINGS.

         The headings contained in this Agreement are for reference purposes
only and shall not in any way affect the meaning or interpretation of this
Agreement.

         SECTION 18.  GENDER; USAGE.

         Whenever used herein the singular number shall include the plural, the
plural shall include the singular, and the use of any gender shall include all
genders.  The words "hereof," "herein" and "hereunder," and words of similar
import, when used in this Agreement shall refer to this Agreement as a whole
and not to any particular provision of this Agreement.

         SECTION 19.  GOVERNING LAW.

         THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED AND ENFORCED





                                       31
<PAGE>   35
IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK OTHER THAN THE CONFLICTS
OF LAWS PRINCIPLES THEREOF.

         SECTION 20.      TERMINATION.

         The rights of any Holder under SECTIONS 2 and 3 of this Agreement
shall terminate as to any Registrable Securities when such Registrable
Securities have been effectively registered under the Securities Act and sold
pursuant to a Registration Statement or Shelf Registration Statement covering
such Registrable Securities.  The indemnification and contribution provisions
of SECTIONS 6 and 7 shall survive any termination of this Agreement.

         SECTION 21.      EXPENSES.

         The Company shall be obligated to pay to the Holders, on demand, all
costs and expenses (including, without limitation, court costs and attorneys'
fees and expenses and interest to the extent permitted by applicable law on
overdue amounts) paid or  incurred in collecting any sums due from, or
enforcing any other obligations of, the Company.

         SECTION 22.      SPECIFIC PERFORMANCE.

         The Company recognizes that the rights of the Holders under this
Agreement are unique and, accordingly, the Holders shall, in addition to such
other remedies as may be available to any of them at law or in equity, have the
right to enforce their rights hereunder by actions for injunctive relief and
specific performance to the extent permitted by law.  The Company agrees that
monetary damages would not be adequate compensation for any loss incurred by
reason of a breach by it of the provisions of this Agreement and hereby agrees
to waive the defense in any action for specific performance that a remedy at
law would be adequate.  This Agreement is not intended to limit or abridge any
rights of the Holders which may exist apart from this Agreement.

         IN WITNESS WHEREOF, the parties hereto have caused this Agreement to
be executed by their respective officers thereunto duly authorized as of the
day and year first above written.
