Item 5.  Other Events


     Execution of Agreement and Plan of Merger and Reorganization
     ------------------------------------------------------------

     On July 5, 1998, Davel Communications Group, Inc., an Illinois corporation
(the "Company"), Davel Holdings, Inc., a Delaware corporation and a wholly owned
subsidiary of the Company ("New Davel"), and Peoples Telephone Company, Inc., a
New York corporation ("Peoples"), entered into an Agreement and Plan of Merger
and Reorganization (the "Merger Agreement"). Pursuant to the Merger Agreement,
Peoples will become a subsidiary of the Company, or, in the event that the
Company's previously announced merger with PhoneTel Technologies, Inc. (the
"PhoneTel Transaction") is completed, of New Davel.  Holders of issued and
outstanding shares of the common stock, $.01 par value per share, of Peoples
(the "Peoples Common Stock") will receive in exchange therefor .235 share of the
common stock of the Company or, if the PhoneTel Transaction is completed, of New
Davel.  The exchange ratio is fixed and is not subject to adjustment.  Based on
the Company's closing stock price of $24.9375 on July 2, 1998, the last trading
day prior to the execution of the Merger Agreement, the Peoples Common Stock
would be valued at $5.86 per share. The transaction is conditioned on its being
accounted for as a pooling of interests and is expected to be tax free to
shareholders of Peoples and the Company.  A representative of UBS Capital II LLC
("UBS"), a significant shareholder of Peoples, will serve on the Company's Board
of Directors for a one-year period.

     In connection with the execution of the Merger Agreement, the Company and
Peoples also entered into a Termination Option Agreement, dated as of July 5,
1998, pursuant to which Peoples granted the Company an option to purchase up to
3,226,274 shares of newly issued Peoples Common Stock, at a price of $5.86 per
share, subject to certain adjustments (the "Option"). The Option becomes
exercisable in the event that the Merger Agreement is terminated under certain
conditions.

     The transaction, which is expected to close in the fall of 1998, is subject
to the approval of the shareholders of both companies and receipt of regulatory
approvals.  UBS entered into a voting agreement with the Company pursuant to
which UBS has agreed to vote all of the shares of  Peoples Common Stock owned by
it in favor of the transaction.  In addition, David R. Hill, Chairman of the
Company, and Samstock, L.L.C., a significant shareholder of the Company, have
entered into voting agreements with Peoples to vote all of the shares of Company
common stock owned by them in favor of the transaction.  The transaction is
subject to certain other conditions, including the conversion by UBS of the
Peoples Series C Cumulative Preferred Stock held by it into Peoples Common Stock
and completion of a cash tender offer for Peoples' 12 1/4% Senior Notes due
2002, pursuant to which a minimum of 80% of the $100 million principal amount
outstanding shall have been tendered.  Satisfaction of these conditions is
dependent upon receipt by the Company of financing, which is expected to be
obtained through a combination of high yield debt and a senior credit facility.

                                   --------

          WHEREAS, the Boards of Directors of Parent, Holdings and the Company

this Agreement;

          WHEREAS, the respective Boards of Directors of Parent, Holdings and

Option Agreement dated as of the date of this Agreement (the "Termination Option

                                   ARTICLE 1

                                   THE MERGER

          SECTION 1.01   The Merger.
                         ---------- 

               (a)  At the Effective Time (as defined in Section 1.01(b)
     hereof), Newco shall be merged (the "Merger") with and into the Company in
                                          ------ 
     accordance with the New York Business Corporation Law ("New York Law"),
                                                             ------------
     whereupon the separate existence of Newco shall cease, and the Company
     shall be the surviving corporation (the "Surviving Corporation"). The
                                              ---------------------
     Merger and the other transactions contemplated hereby are sometimes
     hereinafter referred to as the "Transaction."
                                     ----------- 

               (b)  As soon as practicable after satisfaction or, to the extent
     permitted hereunder, waiver of all conditions to the Merger, the Company
     and Newco will cause a certificate of merger to be executed, verified and
     delivered for filing by the New York Department of State (the "Certificate
                                                                    ----------- 
     of Merger") and make all other filings or recordings required by New York
        ------  
     Law in connection with the Merger. The Merger shall become effective at
     such time as the Certificate of Merger is duly filed by the New York
     Department of State and any additional requirements of New York Law are
     complied with or at such later time as is specified in the Certificate of
     Merger (the "Effective Time").
                  --------------

               (c)  From and after the Effective Time, the Surviving Corporation
     shall possess all the assets, rights, privileges, powers and franchises and
     be subject to all of the liabilities, restrictions, disabilities and duties
     of the Company and Newco, all as provided under New York Law.

          SECTION 1.02   Conversion of Shares.
                         -------------------- 

               (a)  At the Effective Time and by virtue of the Merger and
     without any action on the part of the holders thereof:

                    (i)  each share of common stock of the Company held by the
          Company as treasury stock or owned by Parent, Holdings, Newco or any
          subsidiary of either of them immediately prior to the Effective Time
          shall be canceled, and no payment shall be made with respect thereto;
          provided, however, that any shares of common stock of the Company as
          to which the Company, Holdings or Parent is or may be required to act
          as a fiduciary or in a similar capacity shall not be canceled but,
          instead, shall be treated as set forth in Section 1.02(a)(iii) below;

                    (ii)  each share of capital stock of Newco outstanding
          immediately prior to the Effective Time shall be converted into and
          become one share of capital stock of the Surviving Corporation with
          the same rights and privileges as the shares so converted and shall
          constitute the only outstanding shares of capital stock of the
          Surviving Corporation; and

                                      -2-
<PAGE>
 
                    (iii) subject to Section 1.03(e) and Section 1.04 hereof,
          each share (a "Share") of common stock of the Company, $0.01 par value
                         -----
          per share (the "Company Common Stock"), outstanding immediately prior
                          -------------------- 
          to the Effective Time shall, except as otherwise provided in clause
          (i) of this subsection, be converted into the right to receive .235
          (the "Exchange Ratio") fully paid and nonassessable shares of common
                --------------  
          stock, no par value (the "Parent Common Stock"), of Parent (the
                                    -------------------
          "Merger Consideration"). As of the Effective Time, all such Shares
           --------------------
          shall no longer be outstanding and shall automatically be canceled and
          retired and shall cease to exist, and each holder of a certificate
          representing any such Company Common Stock shall cease to have any
          rights with respect thereto, except the right to receive the Merger
          Consideration and any cash in lieu of fractional shares of Parent
          Common Stock to be issued or paid in consideration therefor upon
          surrender of such certificate in accordance with Section 1.03 hereof,
          without interest.

     SECTION 1.03  Exchange of Shares.
                   ------------------ 

          (a)  As of the Effective Time, Parent or Holdings, as applicable,
     shall enter into an agreement with ChaseMellon Shareholder Services,
     L.L.C., as exchange agent for the Merger (the "Exchange Agent"), which
                                                    --------------  
     shall provide that Parent or Holdings, as applicable, shall deposit with
     the Exchange Agent as of the Effective Time, for the benefit of the holders
     of Shares, for exchange in accordance with this Article 1, through the
     Exchange Agent, certificates representing the shares of Parent Common Stock
     or, if applicable, Holdings Common Stock (as defined below) (such shares of
     Parent Common Stock or Holdings Common Stock, together with any dividends
     or distributions with respect thereto with a record date after the
     Effective Time, any Excess Shares (as defined in Section 1.03(e) hereof)
     and any cash (including cash proceeds from the sale of the Excess Shares)
     payable in lieu of any fractional shares of Parent Common Stock being
     hereinafter referred to as the "Exchange Fund") issuable pursuant to
                                     -------------  
     Section 1.02 hereof in exchange for outstanding Shares.

          (b)  As soon as reasonably practicable after the Effective Time,
     the Exchange Agent shall mail to each holder of record of a certificate or
     certificates which immediately prior to the Effective Time represented
     outstanding Company Common Stock (the "Certificates") whose shares were
                                            ------------                    
     converted into the right to receive the Merger Consideration, pursuant to
     Section 1.02 hereof, (i) a letter of transmittal (which shall specify that
     delivery shall be effected, and risk of loss and title to the Certificates
     shall pass, only upon delivery of the Certificates to the Exchange Agent
     and shall be in such form and have such other provisions as Parent or, if
     applicable, Holdings may reasonably specify) and (ii) instructions for use
     in surrendering the Certificates in exchange for certificates representing
     the Merger Consideration, as applicable.  Upon surrender of a Certificate
     for cancellation to the Exchange Agent, together with such letter of
     transmittal, duly executed, and such other documents as may reasonably be
     required by the Exchange Agent, the holder of such Certificate shall be
     entitled to receive in exchange therefor a certificate representing that
     number of whole shares of Parent Common Stock or, if applicable, Holdings
     Common Stock which such holder has the right to receive pursuant to the
     provisions of this Article 1, certain dividends or other distributions in
     accordance with Section 1.03(c) hereof and cash in lieu of any fractional
     share of Parent Common Stock or, if applicable, Holdings Common Stock 

                                      -3-
<PAGE>
 
     in accordance with Section 1.03(e) hereof, and the Certificate so
     surrendered shall forthwith be canceled. In the event of a transfer of
     ownership of Shares which is not registered in the transfer records of the
     Company, a certificate representing the proper number of shares of Parent
     Common Stock or, if applicable, Holdings Common Stock may be issued to a
     person other than the person in whose name the Certificate so surrendered
     is registered if such Certificate is properly endorsed or otherwise in
     proper form for transfer and the person requesting such issuance pays any
     transfer or other taxes required by reason of the issuance of shares of
     Parent Common Stock or, if applicable, Holdings Common Stock to a person
     other than the registered holder of such Certificate or establishes to the
     satisfaction of Parent that such tax has been paid or is not applicable.
     Until surrendered as contemplated by this Section 1.03, each Certificate
     shall be deemed at any time after the Effective Time to represent only the
     right to receive upon such surrender the Merger Consideration, which the
     holder thereof has the right to receive in respect of such Certificate
     pursuant to the provisions of this Article 1, certain dividends or other
     distributions in accordance with Section 1.03(c) hereof and cash in lieu of
     any fractional share of Parent Common Stock or Holdings Common Stock in
     accordance with Section 1.03(e) hereof. No interest shall be paid or will
     accrue on any cash payable to holders of Certificates pursuant to the
     provisions of this Article 1.

               (c)  No dividends or other distributions with respect to Parent
     Common Stock or, if applicable, Holdings Common Stock with a record date
     after the Effective Time shall be paid to the holder of any unsurrendered
     Certificate with respect to the shares of Parent Common Stock or Holdings
     Common Stock represented thereby, and, in the case of Certificates
     representing Company Common Stock, no cash payment in lieu of fractional
     shares shall be paid to any such holder pursuant to Section 1.03(e) hereof,
     and all such dividends, other distributions and cash in lieu of fractional
     shares of Parent Common Stock or, if applicable, Holdings Common Stock
     shall be paid by Parent or, if applicable, Holdings to the Exchange Agent
     and shall be included in the Exchange Fund, in each case until the
     surrender of such Certificate in accordance with this Article 1.  Subject
     to the effect of applicable escheat or similar laws, following surrender of
     any such Certificate there shall be paid to the holder of the certificate
     representing whole shares of Parent Common Stock or Holdings Common Stock
     issued in exchange therefor, without interest, (i) at the time of such
     surrender, the amount of dividends or other distributions with a record
     date after the Effective Time theretofore paid with respect to such whole
     shares of Parent Common Stock or Holdings Common Stock, and, in the case of
     Certificates representing Company Common Stock, the amount of any cash
     payable in lieu of a fractional share of Parent Common Stock or, if
     applicable, Holdings Common Stock to which such holder is entitled pursuant
     to Section 1.03(e) hereof, and (ii) at the appropriate payment date, the
     amount of dividends or other distributions with a record date after the
     Effective Time but prior to such surrender and with a payment date
     subsequent to such surrender payable with respect to such whole shares of
     Parent Common Stock or Holdings Common Stock.

               (d)  All shares of Parent Common Stock or, if applicable,
     Holdings Common Stock issued upon the surrender for exchange of
     Certificates in accordance with the terms of this Article 1 (including any
     cash paid pursuant to this Article 1) shall be deemed to have been issued
     (and paid) in full satisfaction of all rights pertaining to the 

                                      -4-
<PAGE>
 
     Company Common Stock theretofore represented by such Certificates, subject,
     however, to the Surviving Corporation's obligation to pay any dividends or
     make any other distributions with a record date prior to the Effective Time
     which may have been declared or made by the Company on such shares of
     Company Common Stock which remain unpaid at the Effective Time, and there
     shall be no further registration of transfers on the stock transfer books
     of the Surviving Corporation of the shares of Company Common Stock which
     were outstanding immediately prior to the Effective Time. If, after the
     Effective Time, Certificates are presented to the Surviving Corporation or
     the Exchange Agent for any reason, they shall be canceled and exchanged as
     provided in this Article 1, except as otherwise provided by law.

               (e)  (i)  No certificates or scrip representing fractional
          shares of Parent Common Stock or, if applicable, Holdings Common Stock
          shall be issued upon the surrender for exchange of Certificates, no
          dividend or distribution of Parent or, if applicable, Holdings shall
          relate to such fractional share interests and such fractional share
          interests will not entitle the owner thereof to vote or to any rights
          of a stockholder of Parent or Holdings.

               (ii) As promptly as practicable following the Effective Time, the
          Exchange Agent shall determine the excess of (A) the number of whole
          shares of Parent Common Stock or, if applicable, Holdings Common Stock
          delivered to the Exchange Agent by Parent or Holdings pursuant to
          Section 1.03(a) hereof over (B) the aggregate number of whole shares
          of Parent Common Stock or, if applicable, Holdings Common Stock to be
          distributed to former holders of Company Common Stock pursuant to
          Section 1.03(b) hereof (such excess being herein called the "Excess
                                                                       ------
          Shares"). Following the Effective Time, the Exchange Agent shall, on

          behalf of former holders of Certificates representing Company Common
          Stock, sell the Excess Shares at then-prevailing prices on the Nasdaq
          National Market, all in the manner provided in Section 1.03(e)(iii)
          hereof.

               (iii)  The sale of the Excess Shares by the Exchange Agent shall
          be executed on the Nasdaq National Market in round lots to the extent
          practicable. The Exchange Agent shall use reasonable efforts to
          complete the sale of the Excess Shares as promptly following the
          Effective Time as, in the Exchange Agent's sole judgment, is
          practicable consistent with obtaining the best execution of such sales
          in light of prevailing market conditions. Until the net proceeds of
          such sale or sales have been distributed to the holders of
          Certificates formerly representing Company Common Stock, the Exchange
          Agent shall hold such proceeds in trust for such holders (the "Common
                                                                         ------
          Stock Trust"). The Surviving Corporation shall pay all commissions,

          transfer taxes and other out-of-pocket transaction costs, including
          the expenses and compensation of the Exchange Agent incurred in
          connection with such sale of the Excess Shares. The Exchange Agent
          shall determine the portion of the Common Stock Trust to which each
          former holder of Company Common Stock is entitled, if any, by
          multiplying the amount of the aggregate net proceeds comprising the
          Common Stock Trust by a fraction, the numerator of which is the amount
          of the fractional share interest to which such former holder of
          Company Common Stock is entitled (after taking into account all shares
          of Company Common Stock held at the 

                                      -5-

          Effective Time by such holder) and the denominator of which is the
          aggregate amount of fractional share interests to which all former
          holders of Company Common Stock are entitled.

                    (iv) Notwithstanding the provisions of Section 1.03(e)(ii)
          and (iii) hereof, the Surviving Corporation may elect at its option,
          exercised prior to the Effective Time, in lieu of the issuance and
          sale of Excess Shares and the making of the payments hereinabove
          contemplated, to pay each former holder of Company Common Stock an
          amount in cash equal to the product obtained by multiplying (A) the
          fractional share interest to which such former holder (after taking
          into account all shares of Company Common Stock held at the Effective
          Time by such holder) would otherwise be entitled by (B) the closing
          price for a share of Parent Common Stock or, if applicable, Holdings
          Common Stock as reported on the Nasdaq National Market (as reported in
          The Wall Street Journal, or, if not reported thereby, any other

          authoritative source) on the Closing Date, and, in such case, all
          references herein to the cash proceeds of the sale of the Excess
          Shares and similar references shall be deemed to mean and refer to the
          payments calculated as set forth in this Section 1.03(e)(iv).

                    (v) As soon as practicable after the determination of the
          amount of cash, if any, to be paid to holders of Certificates formerly
          representing Company Common Stock with respect to any fractional share
          interests, the Exchange Agent shall make available such amounts to
          such holders of Certificates formerly representing Company Common
          Stock subject to and in accordance with the terms of Section 1.03(c)
          hereof.

               (f)  Any portion of the Exchange Fund which remains undistributed
     to the holders of the Certificates for six months after the Effective Time
     shall be delivered to Parent or, if applicable, Holdings, upon demand, and
     any holders of the Certificates who have not theretofore complied with this
     Article 1 shall thereafter look only to Parent or, if applicable, Holdings
     for payment of their claims for Merger Consideration, any dividends or
     distributions with respect to Parent Common Stock or Holdings Common Stock,
     as applicable, and any cash in lieu of fractional shares of Parent Common
     Stock or Holdings Common Stock.

               (g)  None of Parent, Holdings, the Company nor the Exchange Agent
     shall be liable to any person in respect of any shares of Parent Common
     Stock or Holdings Common Stock, any dividends or distributions with respect
     thereto, any cash in lieu of fractional shares of Parent Common Stock or
     Holdings Common Stock or any cash from the Exchange Fund, in each case,
     delivered to a public official pursuant to any applicable abandoned
     property, escheat or similar law. If any Certificate shall not have been
     surrendered prior to two years after the Effective Time (or immediately
     prior to such earlier date on which any Merger Consideration, any dividends
     or distributions payable to the holder of such Certificate or any cash
     payable to the holder of such Certificate formerly representing Company
     Common Stock pursuant to this Article 1, would otherwise escheat to or
     become the property of any Governmental Entity (as defined in Section 3.05
     hereof)), any such

     Certificate or such cash shall, to the extent permitted by applicable law,
     become the property of the Surviving Corporation, free and clear of all
     claims or interest of any person previously entitled thereto.

               (h)  The Exchange Agent shall invest any cash included in the
     Exchange Fund, as directed by Parent or, if applicable, Holdings, on a
     daily basis. Any interest and other income resulting from such investments
     shall be paid to Parent or, if applicable, Holdings.

               (i)  If any Certificate shall have been lost, stolen or
     destroyed, upon the making of an affidavit of that fact by the person
     claiming such Certificate to be lost, stolen or destroyed and, if required
     by the Surviving Corporation, the posting by such person of a bond in such
     reasonable amount as the Surviving Corporation may direct as indemnity
     against any claim that may be made against it with respect to such
     Certificate, the Exchange Agent shall issue in exchange for such lost,
     stolen or destroyed Certificate the Merger Consideration and, if
     applicable, any unpaid dividends and distributions on shares of Parent
     Common Stock or Holdings Common Stock deliverable in respect thereof and
     any cash in lieu of fractional shares, in each case, due to such person
     pursuant to this Agreement.

     Parent and Holdings after consultation with one another; provided, however,

     Form S-8 (or other appropriate form) registering a number of shares of

     statement shall be kept effective (and the current status of the prospectus
     required thereby shall be maintained), if then required by the SEC, for at
     least as long as Adjusted Options, Adjusted Warrants or Company Awards
     remain outstanding.

               (e) As soon as practicable after the Effective Time, Parent (or,
     if applicable, Holdings) shall deliver to the holders of the options
     granted under the Company Stock Option Plans, Warrants and Company Awards

     same terms and conditions (subject to the adjustments required by this
     Section 1.05 after giving effect to the Merger).

          SECTION 3.14   Change of Control Provisions.  Except as disclosed in
                         ----------------------------

- -------------                                                                 
3.13 hereof and none of the Company's or any Subsidiary's employee benefit
plans, programs or arrangements contains any provision that would become
operative as the result of the Merger or any other transactions contemplated by
this Agreement.

          SECTION 3.15   Employee Benefit Plans.
                         ---------------------- 

               (a)  Except as set forth on Schedule 3.15 hereto, all of the (i)
                                          -------------                       
     Plans (as defined in subsection (b) of this Section 3.15), and (ii) other
     bonus, insurance, pension, profit sharing, retirement, health, and other
     benefit plans, stock option plans and stock purchase or ownership plans
     currently maintained by the Company or any of the Subsidiaries or to which
     the Company or any of the Subsidiaries is a party may be terminated by the
     Surviving Corporation following the Effective Time without material
     financial penalty or premium and there will be no obligation of the
     Surviving Corporation or Parent following the Effective Time to issue any
     shares of their respective capital stock pursuant to any of the foregoing
     or otherwise following the Effective Time.  Except as set forth in Schedule
                                                                        --------
     3.15 hereto, no payment by the Company or any of the Subsidiaries to any
     ----                                                                    
     person (whether payable or distributable pursuant to the foregoing
     agreements and plans, this Agreement or otherwise) will be nondeductible by
     the Company or any of the Subsidiaries for federal income tax purposes
     because of Section 280G of the Code.

               (b)  Except as set forth on Schedule 3.15 hereto, all employee
                                          -------------                     
     benefit plans within the meaning of Section 3(3) of the Employee Retirement
     Income Security Act of 1974, as amended ("ERISA"), maintained by the
                                               -----                     
     Company or any of the Subsidiaries since December 31, 1997 (collectively,
     the "Plans") are in material compliance with, and have been administered
          -----                                                              
     and operated in all material respects in accordance with, the terms of such
     Plans and applicable law, and the Internal Revenue Service has determined
     that each such Plan which is intended to be "qualified" within the meaning
     of Section 401(a) of the Code 

                                     -17-
<PAGE>
 
     is so qualified and that each related trust is exempt from tax under
     Section 501(a) of the Code. No event which constitutes a "reportable event"
     as defined in Section 4043 of ERISA for which the 30-day notice requirement
     to the Pension Benefit Guaranty Corporation has not been waived has
     occurred and is continuing with respect to any Plan subject to Title IV of
     ERISA. No material liability under any statutes, orders, governmental rules
     or regulations applicable to any Plan, including, without limitation, ERISA
     and the Code, has been or may reasonably be expected to be incurred with
     respect to any Plan (other than liabilities for premiums to the Pension
     Benefit Guaranty Corporation and the payment of contributions and benefits
     in the ordinary course) that has not been satisfied in full. No Plan has
     been terminated pursuant to Title IV of ERISA. No event has occurred and no
     condition exists with respect to any Plan which presents a material risk of
     termination or partial termination of any Plan, which could reasonably be
     anticipated to result in material liability on the part of the Company or
     any of the Subsidiaries. Full payment has been made, or provision has been
     made therefor in the Company's or a Subsidiary's financial statements or
     records, of all amounts which the Company or any of the Subsidiaries were
     required under the terms of the Plans to have paid as contributions to such
     Plans on or prior to the date hereof and no Plan which is subject to Part 3
     of Subtitle B of Title I of ERISA has incurred any "accumulated funding
     deficiency" (within the meaning of Section 302 of ERISA or Section 412 of
     the Code), whether or not waived. Neither the Company nor any of the
     Subsidiaries nor, to the knowledge of the Company, any other "disqualified
     person" or "party in interest" (as defined in Section 4975 of the Code and
     Section 3(14) of ERISA, respectively) has engaged in any nonexempt
     prohibited transactions in connection with any Plan (or its related trust)
     with respect to which the Company, any of the Subsidiaries, or any officer,
     director, employee of the Company or any of the Subsidiaries or, to the
     knowledge of the Company, any trustee, administrator or other fiduciary of
     any Plan, would be subject to either a civil penalty pursuant to Section
     502(i) of ERISA or a tax imposed by Section 4975 of the Code nor, to the
     knowledge of the Company, will the consummation of the transactions
     contemplated by this Agreement constitute such a transaction. Except as
     disclosed on Schedule 3.15 hereto, no claim, action or litigation has been
                  -------------
     made, commenced or, to the knowledge of the Company, threatened with
     respect to any Plan (other than routine claims for benefits). No Plan or
     related trust owns any securities in violation of Section 407 of ERISA. No
     withdrawal by the Company or any of the Subsidiaries, partial or complete,
     within the meaning of Title IV of ERISA, has occurred or may be reasonably
     expected to occur with respect to any Plan which is a multiemployer plan
     which would create a material liability not adequately reserved against by
     the Company. With respect to each employee pension benefit plan (as defined
     in Section 3(2) of ERISA) which is a defined benefit plan and is not a
     multiemployer plan, the assets of such Plan available to meet the accrued
     liabilities of such Plan would exceed such liabilities, based on the
     actuarial assumptions used for plan termination. The Company has paid, or
     has set up an adequate reserve for the payment of, all liabilities under
     each Plan.

          SECTION 3.16   Licenses.  Except as set forth on Schedule 3.16 hereto,
                         --------                          -------------        
the Company and its Subsidiaries have obtained all permits, concessions, grants,
franchises, licenses and other federal, state, local or foreign governmental
authorizations and approvals (collectively, "Licenses") material, individually
                                             --------                         
or in the aggregate, to the conduct of the business of the Company and the
Subsidiaries taken as a whole.  All of such Licenses are in full force and
effect and, to the 

                                      -18-
<PAGE>
 
knowledge of the Company, will not be impaired or adversely affected by the
Transaction in a manner or to a degree that would reasonably be expected to have
a Company Material Adverse Effect. There is not pending or, to the knowledge of
the Company, threatened any domestic or foreign suit or proceeding with respect
to the suspension, revocation, cancellation, modification or non-renewal of any
of such Licenses, and, except as set forth on Schedule 3.16, no event under the
                                              -------------
control of the Company has occurred that (whether with notice or lapse of time,
or both) would reasonably be expected to result in a suspension or revocation of
or failure to renew any of the Licenses, the loss of which would reasonably be
expected to have a Company Material Adverse Effect.

          SECTION 3.17   Real Estate Leases.  Schedule 3.17 hereto sets forth a
                         ------------------   -------------                    
list of (a) all leases and subleases under which the Company or any of the
Subsidiaries is lessor or lessee of any real property, together with all
amendments, supplements, nondisturbance agreements and other agreements
pertaining thereto, (b) all options held by the Company and the Subsidiaries or
contractual obligations on the part of the Company and the Subsidiaries to
purchase or acquire any interest in real property and (c) all options granted by
the Company and the Subsidiaries or contractual obligations on the part of the
Company and the Subsidiaries to sell or dispose of any interest in real
property, in each case, other than site location agreements between the Company
or any of the Subsidiaries and Location Owners ("Site Location Agreements").

          SECTION 3.18   Real Property.  Schedule 3.18 hereto lists all real
                         -------------   -------------                      
property owned, as of the date of this Agreement, by the Company and its
Subsidiaries.  Each of the Company and its Subsidiaries has good and marketable
title in fee simple to its respective real properties set forth on Schedule 3.18
                                                                   -------------
hereto, in each case, to the knowledge of the Company, free and clear of all
liens, except for (a) liens set forth on Schedule 3.18 hereto, (b) mechanics',
                                         -------------                        
construction, carriers', workmen's, repairmen's or other like liens arising or
incurred in the ordinary course of business, (c) liens for taxes and other
governmental charges that are not due and payable or which may thereafter be
paid without penalty, (d) minor survey exceptions, reciprocal easement
agreements and other customary liens on title to real property that (i) were not
incurred in connection with any indebtedness, (ii) do not render title to the
property encumbered thereby unmarketable and (iii) do not, individually or in
the aggregate, materially adversely affect the value of or the use of such
property for its present purposes, and (e) liens in favor of Parent or Holdings.

           SECTION 3.19  Intellectual Property.
                         --------------------- 

               (a) All of the patents, registered trademarks, registered service
     marks, registered copyrights, application for any of the foregoing and

     ----                                                                    
     title and interest in and to, or possess the valid and enforceable right to
     use, the Intellectual Property; (ii) the Company has not received any

     misappropriation from any third party with respect to any material item of
     Intellectual Property; and (iii) the Company and 

                                      -19-

     its Subsidiaries are not currently infringing and, except as set forth on

Company has approved this Agreement and the consummation of the Merger and the

inability of the Company, Parent or Holdings to receive the proceeds from such
Financing.

     portion of the business or assets of the Company and the Subsidiaries.

               (b) The Company shall advise Parent in writing of (i) the

the contrary contained in this Agreement or in the Schedules hereto, the Company
and each Subsidiary shall use reasonable best efforts to be duly qualified and
in good standing on the Effective Date with the Secretary of State in each
jurisdiction in which the character of its properties owned or held under lease
or the nature of its activities makes such qualification necessary.

          SECTION 5.06   Termination Option Agreement.   The Company will fully
                         ----------------------------

receipt of funds sufficient for such purposes from the proceeds of the
Financing, use reasonable best efforts to (i) consummate a tender offer for all
of the Company's 12 1/4% Senior Notes due 2002 (the "Notes") at a price
                                                     -----             
reasonably acceptable to Parent, pursuant to which at least 85% of the aggregate
outstanding principal amount of the Notes shall have been tendered (it being
understood and agreed that (A) Parent and Holdings will use their reasonable
best efforts to obtain the Financing and (B) any failure to receive tenders of
at least 85% of the aggregate outstanding principal amount of the Notes shall
not be a breach of the covenant set forth in this Section 5.07), (ii) procure
the consent of the requisite principal amount of the Notes to allow the Company
to amend the indenture governing the Notes in a manner reasonably satisfactory
to Parent and (iii) enter into a supplemental indenture with respect to the
Notes reflecting such amendments.

     that such employees are eligible to participate in as of the Closing Date.

               (d) As of the Closing Date, Parent or Holdings shall, or shall
     cause the Company or the Parent Subsidiaries to, provide coverage and
     benefits to Affected Employees pursuant to the employee benefit plans or

     reasonable best efforts to cause the Proxy Statement to be mailed to their
     respective stockholders as promptly as practicable after the Form S-4 is

     Company or Parent, or any of their respective affiliates, officers or
     directors, should be discovered by the Company or Parent which should be
     set forth in an amendment or supplement to any of the Form S-4 or the Proxy
     Statement, so that any of such documents would not include any misstatement
     of a material fact or omit to state any material fact necessary to make the
     statements therein, in light of the circumstances under which they were
     made, not misleading, the party which discovers such information shall
     promptly notify the other party hereto and an appropriate amendment or

     contemplated hereby (provided that the termination described in this
                          --------

               (j) by the Company, if the Davel/PhoneTel Merger Agreement has
     been amended, or any obligation of PhoneTel thereunder has been waived, and
     such waiver or amendment causes a material reduction in the value of the
     Merger Consideration to the holders of Company Common Stock or any
     reduction in the value of the Merger Consideration to the holders of
     Company Common Stock that does not have the same relative impact on holders
     of Parent Common Stock (or, after the Davel/PhoneTel Merger, on such
     holders whose Parent Common Stock has been exchanged for Holdings Common
     Stock).

inaccuracies in the representations and warranties contained herein or in any
document delivered pursuant hereto, and (c) except for the requirements set
forth in Sections 8.01(a) through (f), waive compliance with any of the

hereto to any such extension or waiver shall be valid if set forth in an
instrument in writing signed on behalf of such party.

          SECTION 9.03    Closing. Subject to the satisfaction of the conditions
                          -------
contained in Article 8 hereof, the closing of the Merger contemplated by this
Agreement (the "Closing") shall take place at the offices of Kirkland & Ellis 
                -------
in Chicago, Illinois as soon as practicable after the satisfaction or waiver of
all of the conditions to the Merger contained in Article 8 hereof or at such
other time and place as Parent and the Company shall agree (the "Closing Date").

                          -------------------------------------- 

               (a) If this Agreement is terminated pursuant to Section 9.01
     hereof, this Agreement shall become void and of no effect with no liability
     on the part of any party hereto, except that the agreements contained in
     Sections 7.13, 9.04(b) and 10.04 hereof shall survive the termination
     hereof and the Termination Option Agreement shall survive in accordance
     with its terms, and except that no such termination shall relieve any party
     from liability for breach of this Agreement or failure by it to perform its
     obligations hereunder.

               (b) If (i) Parent or Holdings shall have terminated this
     Agreement pursuant to clause (e) of Section 9.01 hereof or (ii) the Company
     shall have terminated this Agreement pursuant to clause (h) of Section 9.01
     hereof, then in either such case, the Company shall promptly, but in no
     event later than two business days after the date of such failure to close
     or termination, pay Parent a termination fee of $5,000,000 plus an amount,
     not to exceed $1,000,000, equal to the actual and reasonably documented
     out-of-pocket expenses incurred by Parent and Equity Group Investments,
     Inc. directly attributable to the proposed acquisition of the Company,
     including negotiation and execution of this Agreement and the attempted
     financing and completion of the Merger, which fee and amount shall be
     payable in same day funds.  In no event shall the Company be required to
     pay more than one termination fee and reimbursement of expenses pursuant to
     this Section 9.04(b).

Dear Sirs:

          The undersigned, a holder of shares of common stock, par value $.01
per share ("Peoples Common Stock"), of Peoples Telephone Company, Inc., a New
            --------------------                                             
York corporation ("Peoples"), is entitled to receive in connection with the
                   -------                                                 
merger (the "Merger") of Peoples with and into a wholly owned subsidiary of
             ------                                                        
Davel Communications Group, Inc., an Illinois corporation ("Davel"), shares of
                                                            -----             
common stock, no par value (the "Davel Common Stock"), of Davel. [SUBSTITUTE
                                 ------------------                         
DAVEL HOLDINGS, INC. FOR DAVEL COMMUNICATIONS GROUP, INC. THROUGHOUT THIS LETTER
IF PHONETEL/DAVEL MERGER HAS OCCURRED.]  The undersigned has been advised that
the undersigned may be deemed an "affiliate" of Peoples within the meaning of
Rule 145 ("Rule 145") promulgated under the Securities Act of 1933, as amended
           --------                                                           
(the "Securities Act"), by the Securities and Exchange Commission (the "SEC")
      --------------                                                    ---  
and may be deemed an "affiliate" of Peoples for purposes of qualifying the
Merger for pooling of interests accounting treatment under Opinion 16 of the
Accounting Principles Board and applicable SEC rules and regulations.  Nothing
contained herein should be construed as an admission that I am an "affiliate" of
Peoples as described in the immediately preceding sentence.

          If, in fact, the undersigned were an affiliate under the Securities
Act, the undersigned's ability to sell, assign or transfer the shares of Davel
Common Stock received by the undersigned in exchange for any shares of Peoples
Common Stock in connection with the Merger may be restricted unless such
transaction is registered under the Securities Act or an exemption from such
registration is available.  The undersigned understands that such exemptions are
limited and the undersigned has obtained or will obtain advice of counsel as to
the nature and conditions of such exemptions, including information with respect
to the applicability to the sale of such securities of Rules 144 and 145(d)
promulgated under the Securities Act.  The undersigned understands that Davel
will not be required to maintain the effectiveness of any registration statement
under the Securities Act for the purposes of sale, transfer or other disposition
of shares of Davel Common Stock by the undersigned (other than pursuant to the
Registration Rights Agreement, dated _______, 1998, between Davel and the
undersigned) or take any action (other than to comply with the reporting
requirements of the Securities Exchange Act of 1934, as amended, so long as it
is subject to such requirements) to make compliance with an exemption from
registration available to the undersigned.

          The undersigned hereby represents to and covenants with Davel that the
undersigned will not sell, assign or transfer any of the shares of Davel Common
Stock received by the undersigned in exchange for shares of Peoples Common Stock
in connection with the Merger except (i) pursuant to an effective registration
statement under the Securities Act, (ii) in conformity with the volume and other
limitations of Rule 145 or (iii) in a transaction which, in the opinion of the
general counsel of Davel or other counsel reasonably satisfactory to Davel or as
described in a "no-action" or

                                      A-1
<PAGE>
 
interpretive letter from the staff of the SEC specifically issued with respect
to a transaction to be engaged in by the undersigned, is not required to be
registered under the Securities Act.

          The undersigned hereby further represents to and covenants with Davel
that from the date that is 30 days prior to the Effective Time (as defined in
the Agreement and Plan of Merger, dated as of _______, 1998, by and among Davel,
Davel Holdings, Inc. and Peoples), the undersigned will not sell, transfer or
otherwise dispose of any shares of Peoples Common Stock held by the undersigned
and that the undersigned will not sell, transfer or otherwise dispose of any
shares of Davel Common Stock received by the undersigned in the Merger until
after such time as results covering at least 30 days of post-Merger combined
operations of Peoples and Davel have been published by Davel, in the form of a
quarterly earnings report, an effective registration statement filed with the
SEC, a report to the SEC on Form 10-K, 10-Q or 8-K, or any other public filing
or announcement which includes such combined results of operations, except after
prior written notice to Davel of the undersigned's intention to make such sale
and Davel's determination that such sale would not reasonably be expected to
adversely affect the qualification of the Merger as a pooling-of-interests.

          In the event of a sale or other disposition by the undersigned of
shares of Davel Common Stock pursuant to Rule 145 or other exempt transaction,
the undersigned will supply Davel with evidence of compliance with such Rule, in
the form of a letter in the form of Annex I hereto or the opinion of counsel or
no-action letter referred to above, as the case may be. The undersigned
understands that Davel may instruct its transfer agent to withhold the transfer
of any shares of Davel Common Stock disposed of by the undersigned, but that
(provided such transfer is not prohibited by any other provision of this letter
agreement) upon receipt of such evidence of compliance, Davel shall cause the
transfer agent to effectuate the transfer of the shares of Davel Common Stock
sold as indicated in such letter.

          The undersigned acknowledges and agrees that the legend set forth
below will be placed on certificates representing the Davel Common Stock
received by the undersigned in connection with the Merger or held by a
transferee thereof, which legend will be removed by delivery of substitute
certificates upon receipt of an opinion in form and substance reasonably
satisfactory to Davel from counsel reasonably satisfactory to Davel to the
effect that such legend is no longer required for purposes of the Securities
Act.

          There will be placed on the certificates for Davel Common Stock issued
to the undersigned, or any substitutions therefor, a legend stating in
substance:

          "THE SHARES REPRESENTED BY THIS CERTIFICATE WERE ISSUED PURSUANT TO A
BUSINESS COMBINATION WHICH IS BEING ACCOUNTED FOR AS A POOLING OF INTERESTS, IN
A TRANSACTION TO WHICH RULE 145 PROMULGATED UNDER THE SECURITIES ACT OF 1933
APPLIES.  THE SHARES HAVE NOT BEEN ACQUIRED BY THE HOLDER WITH A VIEW TO, OR FOR
RESALE IN CONNECTION WITH, ANY DISTRIBUTION THEREOF WITHIN THE MEANING OF THE
SECURITIES ACT OF 1933.  THE SHARES MAY NOT BE SOLD, PLEDGED OR OTHERWISE
TRANSFERRED (I) UNTIL SUCH TIME AS DAVEL SHALL HAVE PUBLISHED FINANCIAL RESULTS
COVERING AT LEAST 30 DAYS OF COMBINED OPERATIONS AFTER THE EFFECTIVE TIME AND
(II) EXCEPT IN ACCORDANCE WITH AN EXEMPTION FROM THE REGISTRATION REQUIREMENTS
OF THE SECURITIES ACT OF 1933."

          The undersigned acknowledges that (i) the undersigned has carefully
read this letter and understands the requirements hereof and the limitations
imposed upon the distribution, sale, transfer or other disposition of Davel
Common Stock and (ii) the receipt by Davel of this letter is an inducement to
Davel's obligations to consummate the Merger.

                              Very truly yours,

[Date]


[Name]

          On __________, the undersigned sold shares of common stock (the "Davel
                                                                           -----
Common Stock") of Davel Communications Group, Inc., an Illinois corporation
- ------------                                                               
("Davel"), which were received by the undersigned in connection with the merger
  -----                                                                        
of Peoples Telephone Company, Inc. with and into a wholly owned subsidiary of
Davel.

          Based upon the most recent report or statement filed by Davel with the
Securities and Exchange Commission, the shares of Davel Common Stock sold by the
undersigned were within the prescribed limitations set forth in paragraph (e) of
Rule 144 promulgated under the Securities Act of 1933, as amended (the
"Securities Act").
 --------------

          The undersigned hereby represents that the shares of Davel Common
Stock were sold in "brokers' transactions" within the meaning of Section 4(4) of
the Securities Act or in transactions directly with a "market maker" as that
term is defined in Section 3(a)(38) of the Securities Exchange Act of 1934, as
amended.  The undersigned further represents that the undersigned has not
solicited or arranged for the solicitation of orders to buy the Davel Common
Stock, and that the undersigned has not made any payment in connection with the
offer or sale of the Davel Common Stock to any person other than to the broker
who executed the order in respect of such sale.
          
                               Very truly yours,

                                                                       EXHIBIT B
                                                                       ---------


     (a)   All capitalized terms used but not defined in this Exhibit B shall
have the meanings assigned to them in the Agreement to which this Exhibit B is
attached. For purposes of the provisions contained in this Exhibit B:

           (i)    The term "Common Stock" means the common stock, no par value
     of Davel or, if the PhoneTel/Davel Merger (as defined in the Merger
     Agreement) has occurred, the common stock, par value $.01 per share, of
     Holdings.

           (ii)   The term "Holder" means, at any given time, UBS, provided that
     UBS owns of record shares of Common Stock of the Issuer at such time, and
     any affiliate of UBS who then owns of record Registrable Securities,
     provided that such affiliate has previously executed and delivered a
     written counterpart to this Agreement.

           (iii)  The term "Issuer" means Davel or Holdings, as applicable.

           (iv)   The term "register," "registered" and "registration" refer to
     a registration effected by preparing and filing a registration statement in
     compliance with the Securities Act.

           (v)    The term "Registrable Securities" means shares of Common Stock
     of the Issuer held, from time to time, by any Holder.

           (vi)   The term "Rule 415 Offering" means an offering on a delayed or
     continuous basis pursuant to Rule 415 (or any successor rule to similar
     effect) promulgated under the Securities Act.

           (vii)  The term "SEC" means the Securities and Exchange Commission or
     any governmental agency that is a successor thereto.

           (viii) The term "Securities Act" means the Securities Act of 1933, as
     amended, and the rules and regulations promulgated thereunder.

           (ix)   The term "Shelf Registration Statement" means a registration
     statement intended to effect a shelf registration in connection with a Rule
     415 Offering.

     (b)   On a single occasion, the Issuer shall, upon the written request of
Holder, prepare and file with the SEC a registration statement with respect to
all or any portion of (or at the request of UBS a Shelf Registration Statement
with respect to all shares of) the Issuer's Common Stock acquired by UBS in or
in connection with the Peoples/Davel Merger for distribution of such stock in
the manner or manners specified in such request and use its reasonable best
efforts to cause such registration statement to become effective and keep such
registration statement effective until such time as such shares have been sold
or disposed of thereunder or sold, transferred or otherwise disposed of to a
person that is not a Holder (but in any event, with respect to a registration
statement other than a Shelf Registration Statement, no later than the third
anniversary of the date such 

                                      B-1
<PAGE>
 
registration statement becomes effective); provided, however, that Holder shall
                                           --------  -------
not be entitled to demand registration of Common Stock pursuant to this
paragraph (b) in an underwritten public offering if, at the time of such
request, such Holder does not beneficially own at least 25% of the number of
shares of Common Stock received by UBS in or in connection with the
Peoples/Davel Merger; and provided further that if, at any time after giving a
                          -------- -------
written request for registration (other than a shelf registration) and prior to
the effective date of the registration statement filed in connection with such
request, the managing underwriters of such offering determine that the aggregate
amount of shares requested to be registered by the Holders of the Registrable
Securities, together with the amount of shares requested by all persons and
entities ("Other Persons") exercising (with respect to such offering) incidental
registration rights granted to such Other Persons by Davel or Holdings, could
materially and adversely affect such offering, then the Issuer may reduce the
number of Registrable Securities of such Holders to be included in such offering
to the maximum number of shares that the underwriters deem advisable, and the
Issuer will allocate the number of securities to be registered among such
Holders and Other Persons on a pro rata basis in accordance with the number of
shares each Holder and Other Person initially requested to be sold (it being
understood that if, as a result of such reduction and allocation, less than 75%
of the Registrable Securities requested by such Holders to be included in such
offering are so included, then the Holders shall again be entitled to the
benefits of this paragraph (b)). Notwithstanding the foregoing, if the Issuer
shall furnish to Investor a certificate signed by the Chief Executive, Chief
Operating, or Chief Financial Officer of the Issuer stating that, in the good
faith judgment of a majority of the Issuer's directors, it would be materially
detrimental to the Issuer for such registration statement to be filed, the
Issuer shall have the right to defer such filing for a period of not more than
90 days after receipt of UBS' request; provided that the Issuer may not utilize
this right more than once in any 12-month period.


     (c)   If the Issuer proposes to register any Common Stock to be issued by
it or held by any other person ("Other Securities") in a public offering under
the Securities Act, on a form and in a manner which would permit registration of
Registrable Securities for sale to the public under the Securities Act, it will
give prompt written notice to each Holder of its intention to do so, and upon
the written request of a Holder delivered to the Issuer within fifteen business
days after the giving of any such notice (which request shall specify the
Registrable Securities intended to be disposed of by such Holder and the
intended method of disposition thereof), the Issuer will use its reasonable best
efforts to effect, in connection with the registration of the Other Securities,
the registration under the Securities Act of all Registrable Securities which
the Issuer has been so requested to register by such Holder, to the extent
required to permit the disposition (in accordance with the intended method or
methods thereof as aforesaid) of the Registrable Securities so to be registered,
provided that:
- --------      

           (i) if, at any time after giving such written notice of its intention
     to register any Other Securities and prior to the effective date of the
     registration statement filed in connection with such registration, the
     managing underwriters of such offering or offerings determine that the
     aggregate amount of shares to be registered by the Holders of the
     Registrable Securities, together with all other shares requested by all
     other persons or entities to be included in such offering, could materially
     and adversely affect such offering, then the Issuer may reduce the number
     of Registrable Securities of such Holders or such other persons or entities
     to be included in such offering to the maximum number of shares that the
     underwriters deem advisable, and the Issuer will allocate the number of
     securities to be 

                                      B-2
<PAGE>
 
     registered among such Holders and other persons or entities on a pro rata
     basis in accordance with the number of shares each Holder and other person
     or entity initially requested to be sold.
     
           (ii)   the Issuer shall not be required to effect any registration of
     Registrable Securities under this paragraph (c) incidental to the
     registration of any of its securities in connection with (A) mergers,
     acquisitions or exchange offers on Form S-4 or any successor form, (B)
     dividend reinvestment plans or (C) stock option or other employee benefit
     plans; and

           (iii)  Holders, cumulatively, shall have the right to exercise
     registration rights pursuant to this paragraph (c) without limit during the
     term hereof.

No registration of Registrable Securities effected under this paragraph (c)
shall relieve the Issuer of its obligation to effect a registration of
Registrable Securities pursuant to paragraphs (b) or (c).

     (d)   Whenever the Issuer is required to effect a registration statement
pursuant to paragraphs (b) or (c), the Issuer shall, as expeditiously as
reasonably possible:

           (i)    Prepare and file with the SEC such amendments and supplements
     to such registration statement and the prospectus used in connection
     therewith as may be necessary to comply with the provisions of the
     Securities Act with respect to the disposition of all securities covered
     thereby.

           (ii)   Furnish to the Holders such numbers of copies of a prospectus,
     including a preliminary prospectus, in conformity with the requirements of
     the Securities Act, and such other documents as they may reasonably request
     in order to facilitate the disposition of Registrable Securities covered by
     such registration statement owned by them.

           (iii)  Use its reasonable best efforts to register and qualify the
     securities covered by such registration statement under such other
     securities or Blue Sky laws of such states or other jurisdictions as shall
     be reasonably requested by any Holder, provided that the Issuer shall not
     be required to qualify to do business or to file a general consent to
     service of process in any such states or jurisdictions where it is not so
     subject.

           (iv)   Notify each Holder of Registrable Securities covered by such
     registration statement at any time when a prospectus relating thereto is
     required to be delivered under the Securities Act of the happening of any
     event as a result of which the prospectus included in such registration
     statement, as then in effect, includes an untrue statement of a material
     fact or omits to state a material fact required to be stated therein or
     necessary to make the statements therein not misleading in the light of the
     circumstances then existing, and then use its best efforts to promptly
     correct such statement or omission.  Notwithstanding the foregoing and
     anything to the contrary set forth in this paragraph (d), each Holder
     acknowledges that the Issuer shall have the right to suspend the use of the
     prospectus forming a part of a registration statement if such offering
     would interfere with a pending corporate transaction or for other reasons
     until such time as an amendment to the registration statement has been
     filed by the Issuer and declared effective by the SEC, or until such time
     as the Issuer 

                                      B-3
<PAGE>
 
     has filed an appropriate disclosure report with the SEC. Each Holder hereby
     covenants that it will (i) keep any such notice strictly confidential, and
     (ii) not sell any shares of Common Stock pursuant to such prospectus during
     the period commencing at the time at which the Issuer gives the Holder
     notice of the suspension of the use of such prospectus and ending at the
     time the Issuer gives the Holder notice that it may thereafter effect sales
     pursuant to such prospectus. The Issuer shall only be able to suspend the
     use of such prospectus for periods aggregating no more than 90 days in
     respect of any registration.

           (v)    Make available for inspection by any Holder of Registrable
     Securities included in such registration statement, any underwriter
     participating in any offering pursuant to such registration statement, and
     any attorney, accountant or other agent retained by any such Holder or
     underwriter (collectively, the "Inspectors"), all financial and other
     records and other information, pertinent corporate documents and properties
     of any of the Issuer and its subsidiaries and affiliates (collectively, the
     "Records"), as shall be reasonably necessary to enable them to exercise
     their due diligence responsibilities; provided, however, that the Records
                                           --------  -------                  
     that the Issuer determines, in good faith, to be confidential and which it
     notifies the Inspectors in writing are confidential shall not be disclosed
     to any Inspector unless such Inspector signs a confidentiality agreement
     reasonably satisfactory to the Issuer (which shall permit the disclosure of
     such Records in such registration statement or the related prospectus if
     necessary to avoid or correct a material misstatement in or material
     omission from such registration statement or prospectus) and either (i) the
     disclosure of such Records is necessary to avoid or correct a misstatement
     or omission in such registration statement or (ii) the release of such
     Records is ordered pursuant to a subpoena or other order from a court of
     competent jurisdiction; provided, further, that (A) any decision regarding
                             --------  -------                                 
     the disclosure of information pursuant to subclause (i) shall be made only
     after consultation with counsel for the applicable Inspectors and the
     Issuer and (B) with respect to any release of Records pursuant to subclause
     (ii), each Holder of Registrable Securities agrees that it shall, promptly
     after learning that disclosure of such Records is sought in a court having
     jurisdiction, give notice to the Issuer so that the Issuer, at the Issuer's
     expense, may undertake appropriate action to prevent disclosure of such
     Records.

           (v)    Enter into such customary agreements (including underwriting
     agreements in customary form) and take all such other actions as the
     Holders of a majority of the Registrable Securities being sold or the
     underwriters, if any, reasonably request in order to expedite or facilitate
     the disposition of such Registrable Securities (including obtaining
     opinions of counsel and "cold comfort" letters and updates thereof from the
     Issuer's independent certified public accountants).

     (e)   It shall be a condition precedent to the obligations of the Issuer to
take any action pursuant to this Agreement with respect to the Registrable
Securities of any selling Holder that such Holder shall furnish to the Issuer
such information regarding itself, the Registrable Securities held by it, and
the intended method of disposition of such securities as shall be required to
effect the registration of such Holder's Registrable Securities and as may be
required from time to time to keep such registration current.

                                      B-4
<PAGE>
 
     (f)   All expenses incurred by or on behalf of the Issuer in connection
with registrations, filings or qualifications pursuant to paragraphs (b) or (c),
including, without limitation, all registration, filing and qualification fees,
printers' and accounting fees, and fees and disbursements of counsel for the
Issuer, shall be borne by the Issuer. In no event shall the Issuer be obligated
to bear any underwriting discounts or commissions or brokerage fees or
commissions relating to Registrable Securities or, except as otherwise set forth
herein, the fees and expenses of counsel to the selling Holders.

     (g)   In the event of registration of any Registrable Securities hereunder:

           (i)    To the extent permitted by law, the Issuer will indemnify and
     hold harmless each Holder and the affiliates of such Holder, and their
     respective directors, officers, general and limited partners, agents and
     representatives (and the directors, officers, affiliates and controlling
     persons thereof), and each other person, if any, who controls such Holder
     within the meaning of the Securities Act, against any losses, claims,
     damages, or liabilities ("Losses"), joint or several, to which they may
     become subject under the Securities Act or other federal or state law,
     insofar as such Losses (or actions in respect thereof) arise out of or are
     based upon any of the following statements, omissions or violations
     (collectively a "Violation"): (i) any untrue statement or alleged untrue
     statement of a material fact contained in such registration statement,
     including any preliminary prospectus (provided that this indemnity shall
     not apply to the extent that the Losses are attributable to an untrue
     statement or alleged untrue statement of any material fact or omission or
     alleged omission to state a material fact in a preliminary prospectus that
     was corrected in a final prospectus which was provided to the Holder on a
     timely basis but which the Holder or the underwriters failed to deliver to
     the purchaser within the time required by applicable securities laws)
     contained therein or any amendments or supplements thereto, (ii) 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 (but only if such omission is not corrected in the final
     prospectus), or (iii) any violation or alleged violation by the Issuer in
     connection with the registration of Registrable Securities under the
     Securities Act, any state securities law or any rule or regulation
     promulgated under the Securities Act or any state securities law; and the
     Issuer will pay to each such Holder, affiliate or controlling person, as
     incurred, any legal or other expenses reasonably incurred by them in
     connection with investigating or defending any such Loss or action;
                                                                        
     provided, however, that the indemnity contained in this subparagraph (g)(i)
     --------  -------                                                          
     shall not apply to amounts paid in settlement of any such loss, claim,
     damage, liability or action if such settlement is effected without the
     consent of the Issuer (which consent shall not be unreasonably withheld),
     nor shall the Issuer be liable in any such case for any such loss, claim,
     damage, liability or action to the extent that it arises out of or is based
     upon a Violation which occurs in reliance upon and in conformity with
     written information furnished expressly for use in connection with such
     registration by or on behalf of such Holder or its Affiliates or
     controlling person.  Each indemnified party shall furnish such information
     regarding itself or the claim in question as an indemnifying party may
     reasonably request in writing and as shall be reasonably required in
     connection with the defense of such claim and litigation resulting
     therefrom.

                                      B-5
<PAGE>
 
           (ii)   To the extent permitted by law, each selling Holder will
     indemnify and hold harmless the Issuer, each of its directors, each of its
     officers who has signed the registration statement, each person, if any,
     who controls the Issuer within the meaning of the Securities Act, any
     underwriter, any other Holder selling securities in such registration
     statement and any controlling person of any such underwriter or other
     Holder, against any Losses, joint or several, to which any of the foregoing
     persons may become subject, under the Securities Act or other federal or
     state law, insofar as such losses, claims, damages or liabilities (or
     actions in respect thereto) arise out of or are based upon any Violation,
     in each case to the extent (and only to the extent) that such Violation
     occurs in reliance upon and in conformity with written information
     furnished by such Holder expressly for use in connection with such
     registration; and each such Holder will pay, as incurred, any legal or
     other expenses reasonably incurred by any person intended to be indemnified
     pursuant to this subparagraph (g)(ii) in connection with investigating or
     defending any such loss, claim, damage, liability or action; provided,
                                                                  -------- 
     however, that the indemnity contained in this subparagraph (g)(ii) shall
     -------                                                                 
     not apply to amounts paid in settlement of any such Loss or action if such
     settlement is effected without the consent of such Holder, which consent
     shall not be unreasonably withheld; provided, that, in no event shall any
                                         --------                             
     indemnity under this subparagraph (g)(ii) exceed the gross proceeds from
     the offering received by such Holder.

           (iii)  Promptly after receipt by an indemnified party of notice of
     the commencement of any action (including any governmental action), such
     indemnified party will, if a claim in respect thereof is to be made against
     any indemnifying party under this paragraph (g), deliver to the
     indemnifying party a written notice of the commencement thereof and the
     indemnifying party shall have the right to participate in, and, to the
     extent the indemnifying party so desires, jointly with any other
     indemnifying party similarly noticed, to assume the defense thereof with
     counsel mutually satisfactory to the parties. The failure to deliver
     written notice to the indemnifying party within a reasonable time after the
     commencement of any such action, if materially prejudicial to its ability
     to defend such action, shall relieve such indemnifying party of any
     liability to the indemnified party under this paragraph (g) to the extent
     of such prejudice, but the omission so to deliver written notice to the
     indemnifying party will not relieve it of any liability that it may have to
     any indemnified party otherwise than under this paragraph (g). The
     indemnified party shall have the right, but not the obligation, to
     participate in the defense of any action referred to above through counsel
     of its own choosing and shall have the right, but not the obligation, to
     assert any and all separate defenses, cross claims or counterclaims which
     it may have, and the fees and expenses of such counsel shall be at the
     expense of such indemnified party unless (A) the employment of such counsel
     has been specifically authorized in advance by the indemnifying party, (B)
     there is a conflict of interest that prevents counsel for the indemnifying
     party from adequately representing the interests of the indemnified party
     or there are defenses available to the indemnified party that are different
     from, or additional to, the defenses that are available to the indemnifying
     party, (C) the indemnifying party does not employ counsel that is
     reasonably satisfactory to the indemnified party within a reasonable period
     of time, or (D) the indemnifying party fails to assume the defense or does
     not reasonably contest such action in good faith, in which case, if the
     indemnified party notifies the indemnifying party that it elects to employ
     separate counsel, the indemnifying party shall not have the right to assume
     the defense of such action on behalf of the indemnified party and the
     reasonable fees and expenses of such separate

                                      B-6
<PAGE>
 
     counsel shall be borne by the indemnifying party; provided, however, that,
                                                       --------  -------
     the indemnifying party shall not, in connection with any proceeding or
     related proceedings in the same jurisdiction, be liable for the reasonable
     fees and expenses of more than one separate firm (in addition to, to the
     extent reasonably necessary to employ local counsel, one firm acting as
     local counsel) for all indemnified parties.

           (iv)   If the indemnification provided for in this paragraph (g) is
     unavailable to an indemnified party in respect of any Losses (other than in
     accordance with its terms), then each applicable indemnifying party, in
     lieu of indemnifying such indemnified party, shall contribute to the amount
     paid or payable by such indemnified party as a result of such Losses, in
     such proportion as is appropriate to reflect the relative fault of the
     indemnifying party, on the one hand, and such indemnified party, on the
     other hand, in connection with the actions, statements or omissions that
     resulted in such Losses as well as any other relevant equitable
     considerations.  The relative fault of such indemnifying party, on the one
     hand, and indemnified party, on the other hand, shall be determined by
     reference to, among other things, whether any action in question, including
     any untrue statement of a material fact or omission or alleged omission to
     state a material fact, has been taken by, or relates to information
     supplied by, such indemnifying party or indemnified party, and the parties'
     relative intent, knowledge, access to information and opportunity to
     correct or prevent any such action, statement or omission.  The amount paid
     or payable by a party as a result of any Losses shall be deemed to include
     any legal or other fees or expenses incurred by such party in connection
     with any investigation or proceeding.  No contribution required by this
     paragraph to be made by any Holder shall exceed the gross proceeds from the
     offering received by such Holder.

           (v)    The obligations of the Issuer and the Holders under this
     paragraph (g) shall survive the completion of any offering of Registrable
     Securities in a registration statement under this Agreement.

           (vi)   Notwithstanding the foregoing, to the extent that the
     provisions on indemnification and contribution contained in the
     underwriting agreement (if any) entered into in connection with any
     underwritten public offering of the Registrable Securities are in conflict
     with the foregoing provisions, the provisions in such underwriting
     agreement shall control.

     (h)   With a view to making available to the holders the benefits of Rule
144 and any other rule or regulation of the SEC that may at any time permit a
Holder to sell securities of the Issuer to the public without registration or
pursuant to a registration on Form S-3, the Issuer agrees to:

           (i)    use its reasonable best efforts to make and keep public
     information available, as those terms are understood and defined in Rule
     144;

           (ii)   use its reasonable best efforts to file with the SEC in a
     timely manner all reports and other documents required under the Securities
     Act and the Securities Exchange Act of 1934, as amended; and

                                      B-7
<PAGE>
 
           (iii)  furnish to any Holder forthwith upon request (i) a written
     statement by the Issuer as to its compliance with the reporting
     requirements of Rule 144, or as to whether it qualifies as a registrant
     whose securities may be resold pursuant to Form S-3, (ii) a copy of the
     most recent annual or quarterly report of the Issuer and such other reports
     and documents so filed by the Issuer, and (iii) such other information (and
     the Issuer shall take such action) as may be reasonably requested in
     availing any Holder of any rule or regulation of the SEC which permits the
     selling of any such securities without registration or pursuant to such
     form.

     (i)   The rights to cause the Issuer to register Registrable Securities
pursuant to this Agreement may only be assigned by a Holder to a transferee or
assignee of any Registrable Securities if such transferee or assignee is or
becomes a Holder in connection with such transfer or assignment.

     (j)   The observance by the Issuer of any provision of this Agreement may
be waived (either generally or in a particular instance and either retroactively
or prospectively) with the written consent of the Holders of a majority of the
Registrable Securities, and any waiver effected in accordance with this
paragraph shall be binding upon each Holder of Registrable Securities.

     (k)   Each Holder of Registrable Securities, if requested by an underwriter
of any registered public offering of Issuer securities being sold in a firm
commitment underwriting, agrees not to sell or otherwise transfer or dispose of
any Common Stock (or other voting securities of the Issuer) held by such Holder
other than shares of Registrable Securities included in the registration during
the seven days prior to, and during a period of up to 180 days following, the
effective date of the registration statement.  Such agreement shall be in
writing in a form reasonably satisfactory to the Issuer and such underwriter.
The Issuer may impose stop-transfer instructions with respect to the securities
subject to the foregoing restriction until the end of the required stand-off
period. Notwithstanding the foregoing, Holder shall only be bound by the
provisions of this paragraph (k) if all other holders of Common Stock entitled
to registration rights are similarly restricted.

                         TERMINATION OPTION AGREEMENT

          This TERMINATION OPTION AGREEMENT (this "Agreement"), is made and
                                                   ---------               
entered into as of July 5, 1998, by and among Davel Communications Group, Inc.,
an Illinois corporation (the "Grantee"), and Peoples Telephone Company, Inc., a
                              -------                                          
New York corporation (the "Grantor").
                           -------   

          WHEREAS, concurrently with the execution and delivery of this
Agreement, the Grantor, the Grantee and Davel Holdings, Inc., a Delaware
corporation ("Holdings"), are entering into an Agreement and Plan of Merger and
Reorganization, dated as of the date hereof (the "Merger Agreement"); and
                                                  ----------------       

          WHEREAS, as a condition to the Grantee's willingness to enter into the
Merger Agreement, the Grantee has requested that the Grantor agree, and in order
to induce the Grantee to enter into the Merger Agreement, the Grantor has so
agreed, to grant to the Grantee an option with respect to certain shares of the
Grantor's common stock, $0.01 par value per share (the "Grantor Common Stock"),
                                                        --------------------   
on the terms and subject to the conditions set forth herein.

          NOW, THEREFORE, in consideration of the foregoing and of the mutual
covenants and agreements set forth herein and in the Merger Agreement and for
other good and valuable consideration, the receipt and adequacy of which are
hereby acknowledged, the parties hereto hereby agree as follows:

     1.   Grant of Option.  The Grantor hereby grants to the Grantee an
          ---------------                                              
irrevocable option (the "Stock Option") to purchase up to 3,226,274 shares of
                         ------------                                        
Grantor Common Stock, or such other number of shares of the Grantor Common Stock
as equals 19.9% of the issued and outstanding shares of the Grantor Common Stock
at the time of exercise of the Stock Option, in the manner set forth below, at a
price of $5.86 per share (the "Exercise Price"), payable in cash in accordance
                               --------------                                 
with Section 4 hereof.  Capitalized terms used and not otherwise defined herein
shall have the meanings set forth in the Merger Agreement.

     2.   Exercise of Option.  The Stock Option may be exercised by the Grantee,
          ------------------                                                    
in whole or in part, at any time or from time to time after the termination of
the Merger Agreement pursuant to Sections 9.01(e), 9.01(f) or 9.01(h) thereof.
The Stock Option shall be exercisable until the earliest to occur of (i) the
closing of any transaction pursuant to an Acquisition Proposal with any
corporation, partnership, person, other entity or group (as defined in Section
13(d)(3) of the Exchange Act) other than Grantor or any of its subsidiaries or
affiliates (each a "Third Party"); (ii) any Third Party acquiring beneficial
ownership of more than 50% of the outstanding Grantor Common Stock; or (iii)
twelve (12) months after the date of termination of the Merger Agreement. In the
event the Grantee wishes to exercise the Stock Option, the Grantee shall deliver
to the Grantor a written notice (an "Exercise Notice") specifying the total
                                     ---------------                       
number of shares of the Grantor Common Stock it wishes to purchase.  Each
closing of a purchase of shares of Grantor Common Stock (a "Closing") shall
                                                            -------        
occur at a place, on a date and at a time designated by the Grantee in any
Exercise Notice delivered at least two (2) business days prior to the date of
such Closing.
<PAGE>
 
     3.   Conditions to Closing.  The obligation of the Grantor to issue shares
          ---------------------                                                
of the Grantor Common Stock to the Grantee hereunder is subject to the
conditions (which, other than the conditions described in clauses (a) and (b)
below, may be waived by the Grantor in its sole discretion) that (a) all waiting
periods, if any, under the HSR Act applicable to the issuance of shares of the
Grantor Common Stock hereunder shall have expired or have been terminated, and
all consents, approvals, order or authorization of, or registration,
declarations or filings with, any federal or state administrative agency or
commission or other federal or state governmental authority or instrumentality,
if any, required in connection with the issuance of shares of the Grantor Common
Stock hereunder shall have been obtained or made, as the case may be; (b) no
preliminary or permanent injunction or other order by any court of competent
jurisdiction prohibiting or otherwise restraining such issuance shall be in
effect; (c) any consent under any material contract, agreement or other
instrument to which the Grantor is a party or by which its assets are bound has
been obtained (other than those consents the failure of which to be obtained
would not have a material adverse effect on the Grantor); and (d) such shares
shall have been approved for listing on the American Stock Exchange (or such
other exchange or quotation system upon which the Grantor Common Stock is then
listed or included), subject to official notice of issuance.

     4.   Closing.  At any Closing, (a) the Grantor will deliver to the Grantee
          -------                                                              
a single certificate in definitive form representing the number of shares of the
Grantor Common Stock designated by the Grantee in its Exercise Notice, such
certificate to be registered in the name of the Grantee, or a nominee of the
Grantee designated by the Grantee in the Exercise Notice, and to bear the legend
set forth in Section 9 hereof, and (b) the Grantee will deliver to the Grantor
the aggregate Exercise Price for the shares of the Grantor Common Stock so
designated and being purchased at such Closing by wire transfer of immediately
available funds.

     5.   Representations and Warranties of the Grantor.  The Grantor represents
          ---------------------------------------------                         
and warrants to the Grantee that (a) the Grantor is a corporation duly
organized, validly existing and in good standing under the laws of the State of
New York and has the corporate power and authority to enter into this Agreement
and to carry out its obligations hereunder, (b) the execution and delivery of
this Agreement by the Grantor and the consummation by the Grantor of the
transactions contemplated hereby have been duly authorized by all necessary

     7.   Registration Rights.  In the event that the Grantee shall desire to
          -------------------                                                
sell any of the shares of the Grantor Common Stock purchased pursuant to the
Stock Option within two (2) years after such purchase, and such sale requires in
the opinion of counsel to the Grantor, which opinion shall be reasonably
satisfactory to the Grantee and its counsel, registration of such shares under
the Securities Act of 1933, the Grantee may, by written notice (the
"Registration Notice") to the Grantor, request the Grantor to register under the
 -------------------                                                            
Securities Act all or any part of the shares purchased pursuant to the Stock
Option ("Restricted Shares") beneficially owned by the Grantee (the "Registrable
         -----------------                                           -----------
Securities") pursuant to a bona fide firm commitment underwritten public
- ----------                                                              
offering in which the Grantee and the underwriters shall effect as wide a
distribution of such Registrable Securities as is reasonably practicable and
shall use their best efforts to prevent any person (including any Group) and its
affiliates from purchasing through such offering Restricted Shares representing
more than 2% of the outstanding shares of common stock of the Grantor on a fully
diluted basis (a "Permitted Offering").  The Registration Notice shall include a
                  ------------------                                            
certificate executed by the Grantee and its proposed managing underwriter, which
underwriter shall be an investment banking firm of nationally recognized
standing reasonably acceptable to the Grantor (the "Manager"), stating that (a)
                                                    -------                    
it has a good faith intention to commence promptly a Permitted Offering and (b)
the Manager in good faith believes that, based on the then prevailing market
conditions, it will be able to sell the Registrable Securities at a per share
price to be specified in such Registration Notice (the "Fair Market Value").
                                                        -----------------    
The Grantor (and/or any person designated by the Grantor) shall thereupon have
the option, exercisable by written notice delivered to the Grantee within ten
(10) business days after the receipt of the Registration Notice, irrevocably to
agree to purchase all or any part of the Registrable Securities for cash at a
price (the "Option Price") equal to the product of (a) the number of Registrable
            ------------                                                        
Securities and (b) the Fair Market Value of such Registrable Securities. Any
such purchase of Registrable Securities by the Grantor hereunder shall take
place at a closing to be held at the principal executive offices of the Grantor
or its counsel at any reasonable date and time designated by the Grantor and its
designee in such notice within forty (40) business days after delivery of such
notice.  Any payment for the shares to be purchased shall be made by delivery at
the time of such closing of the Option Price in immediately available funds.  If
the Grantor does not elect to exercise its option pursuant to this Section 7
with respect to all Registrable Securities designated in the Registration
Notice, it shall use its best efforts to effect, as promptly as practicable, the
registration under the Securities Act of the unpurchased Registrable Securities;
provided, however, that (a) the Grantee shall not be entitled to more than an
- --------  -------                                                            
aggregate of two effective registration statements hereunder and (b) the Grantor
will not be required to file any such registration statement during any period
of time (not to exceed 90 days after such request in the case of clause (ii)
below or 150 days in the case of clauses (i) and (iii) below) when (i) the
Grantor is in possession of material non-public information which it reasonably
believes would be detrimental to be disclosed at such time and, in the judgment
of the Board of Directors of the Grantor, such information would have to be
disclosed if a registration statement were filed at that time; (ii) the Grantor
is required under the Securities Act to include audited financial statements for
any period in such registration statement and such financial statements are not
yet available for inclusion in such registration statement; or (iii) the Grantor
determines, in its reasonable judgment, that such registration would interfere
with any financing, acquisition or other material transaction involving the
Grantor or any of its affiliates.  If consummation of the sale of any
Registrable Securities pursuant to a registration hereunder does not occur
within 120 days after the filing with the SEC of the initial registration
statement with respect 

                                      -4-

thereto, the provisions of this Section 7 shall again be applicable to any
proposed registration; provided, however, that the Grantee shall not be entitled
                       --------  -------
to request more than two registrations pursuant to this Section 7 to be
qualified for sale under the securities or blue-sky laws of such jurisdictions
as the Grantee may reasonably request and shall continue such registration or
qualification in effect in such jurisdiction; provided, further, that the
                                              --------  -------
Grantor shall not be required to qualify to do business in, or consent to
general service of process in, any jurisdiction by reason of this provision. The
registration rights set forth in this Section 7 are subject to the condition
that the Grantee shall provide the Grantor with such information with respect to
the Grantee's Registrable Securities, the plans for the distribution thereof,
and such other information with respect to the Grantee as, in the reasonable
judgment of counsel for the Grantor, is necessary to enable the Grantor to
include in such registration statement all material facts required to be
disclosed with respect to a registration thereunder. A registration effected
under this Section 7 shall be effected at the Grantor's expense, except for
underwriting discounts and commissions and the fees and the expenses of counsel
to the Grantee, and the Grantor shall provide to the underwriters such
documentation (including certificates, opinions of counsel and "comfort" letters
from auditors) as are customary in connection with underwritten public offerings
as such underwriters may reasonably require. In connection with any such
registration, the parties agree (a) to indemnify each other and the underwriters
in the customary manner and (b) to enter into an underwriting agreement in form
and substance customary to transactions of this type with the Manager and the
other underwriters participating in such offering.

     8.   Adjustment upon Changes in Capitalization.  In the event of any change
          -----------------------------------------                             
in the Grantor Common Stock by reason of stock dividends, stock splits, mergers
(other than the Merger), recapitalizations, combinations, exchange of shares or
the like, the type and number of shares or securities subject to the Stock
Option, and the Exercise Price per share, shall be adjusted appropriately.

     9.   Restrictive Legends. Each certificate representing shares of the
          -------------------                                             
Grantor Common Stock issued to the Grantee hereunder shall initially be endorsed
with a legend in substantially the following form:

     THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED
     UNDER THE SECURITIES ACT OF 1933, AS AMENDED, AND MAY BE REOFFERED OR SOLD
     ONLY IF SO REGISTERED OR IF AN EXEMPTION FROM SUCH REGISTRATION AND
     APPLICABLE STATE SECURITIES LAWS IS AVAILABLE. SUCH SECURITIES ARE ALSO
     SUBJECT TO ADDITIONAL RESTRICTIONS ON TRANSFER AS SET FORTH IN THE
     TERMINATION OPTION AGREEMENT, DATED JULY 5, 1998, A COPY OF WHICH MAY BE
     OBTAINED FROM THE ISSUER HEREOF.

     10.  Binding Effect; No Assignment.  This Agreement shall be binding upon
          -----------------------------                                       
and inure to the benefit of the parties hereto and their respective successors,
and permitted assigns. Except as expressly provided in this Agreement, neither
this Agreement nor the rights or the obligations of either party hereto are
assignable, except by operation of law, or with the written consent of the other
party; provided, however, that the Grantee may assign its rights and obligations
       --------  -------                                                        
hereunder to Holdings at any time after the consummation of the PhoneTel/Davel
Merger (as defined in the Merger Agreement) and prior to the Closing.  Nothing

intended to confer upon any person other than the parties hereto and their
respective permitted assigns any rights or remedies of any nature whatsoever by
reason of this Agreement. Any Restricted Shares sold by a party in compliance
with the provisions of Section 7 hereof shall, upon consummation of such sale,
be free of the restrictions imposed with respect to such shares by this
Agreement, in no event will any transferee of any Restricted Shares be entitled
to the rights of the Grantee hereunder. Certificates representing shares sold in
a registered public offering pursuant to Section 7 hereof shall not be required
to bear the legend set forth in Section 9 hereof.

     11.  Incorporation by Reference.  The provisions of Sections 10.01, 10.04,

     DAVEL COMMUNICATIONS GROUP AND PEOPLES TELEPHONE ANNOUNCE SIGNING OF
                               MERGER AGREEMENT

    COMBINED COMPANY WILL OPERATE OVER 125,000 PAYPHONES ACROSS THE NATION

TAMPA, Fla. and MIAMI -- July 6 /PRNewswire/ -- Davel Communications Group, Inc.
(Nasdaq: DAVL), and Peoples Telephone Company, Inc. (Amex: PHO), today announced
the signing of a definitive agreement to merge the two companies. The
combination of the companies, when coupled with PhoneTel Technologies, Inc.,
with which Davel recently announced its intention to merge, will be the nation's
largest independent payphone provider, with more than 125,000 installed
payphones and pro forma 1997 revenues in excess of $320 million. The merger of
the companies is expected to result in significant cost savings from lower line
and transmission costs, lower field operating costs through more efficient
concentration of payphone routes, and elimination of redundant general and
administrative expenses.

Under the terms of the agreement, which has been approved by the Board of
Directors of each company, holders of common stock of Peoples Telephone will
received 0.235 shares of Davel common stock for each outstanding share of
Peoples Telephone common stock. The exchange ratio is fixed and not subject to
adjustment. The companies expect the transaction to be tax-free to shareholders
of both companies. Based on Davel's closing price of $24.9375 on July 2, 1998,
the transaction is valued at $5.86 per share of Peoples Telephone common stock.

The transaction, which is intended to close in the fall of 1998, is subject to
the approval of the shareholders of both companies, receipt of required
regulatory approvals and other customary conditions. Consummation of the merger
is conditioned on its eligibility for pooling-of-interests accounting treatment.
The transaction is also subject to conversion of Peoples Telephone's convertible
preferred stock into common stock and receipt by Davel of financing for, and
successful consummation of, a cash tender offer for Peoples' 12 1/4% Senior
Notes due 2002, pursuant to which a minimum of 85% of the aggregate outstanding
principal amount of $100 million shall have been tendered. The refinancing of
the combined companies' indebtedness will be achieved through a combination of
high yield debt and a senior credit facility. No assurances can be given that
all of the conditions to consummation of the proposed merger will be satisfied.
The Peoples Telephone transaction is independent of and not contingent on
consummation of Davel's previously announced merger agreement with PhoneTel.

Robert D. Hill, President and Chief Executive Officer of Davel commented, "The
combination of our operations with Peoples Telephone, a recognized quality
public access leader, presents an exciting opportunity for Davel and its
shareholders. We believe that this transaction creates an opportunity to achieve
meaningful cost savings. In addition to creating significant synergy value, this
merger will provide our combined sales staff with the opportunity to market
payphone services on a truly nationwide basis. For the first time, customers
with a nationwide presence can look to a single payphone provider to fill their
public communications needs throughout the
<PAGE>
 
country."

Peoples Telephone is expected to become a subsidiary of the previously announced
holding company to be formed in connection with the PhoneTel combination which
will be called Davel Communications, Inc. The new company will be headquartered
in Tampa, Florida and will be operated by senior management of Davel
Communications Group. Davel's Board of Directors will be joined for a period of
one year by a representative of UBS Capital II LLC who currently serves on the
Board of Directors of Peoples Telephone.

Commenting on the merger, E. Craig Sanders, President and Chief Executive
Officer of Peoples Telephone said, "This merger, which unites Peoples Telephone
with the Davel organization, is an ideal combination that maximizes value for
our shareholders, and dramatically alters the public communications landscape.
The transaction value of $5.86 per share represents an 88% premium over Peoples
Telephone's closing price on July 2. Peoples believes that the new company, with
Sam Zell's investment, possesses the resources and complementary skills to
compete effectively in the new telecommunications environment. We anticipate
that this merger will yield route density, cost efficiencies and broad service
synergies -- making this an excellent transaction for both our customers and
stakeholders. Peoples' Telephone is excited over the prospects presented by this
combination, and we look forward to the days ahead.''

Concluding his comments, Mr. Hill said, "We are fortunate to have the
management, systems and financial resources available to manage the task of
integrating these companies. By combining Peoples Telephone, PhoneTel and
Communications Central Inc. with Davel, we will have created the first
independent payphone provider to rival the size of the Regional Bell Operating
Companies' payphone operations. We further believe that our nationwide footprint
provides us with significant competitive advantages in the areas of marketing
and customer service.'' Davel Communications Group, Inc. operates a system of
approximately 40,000 pay telephones in 36 states and the District of Columbia
and provides long distance operator services for its payphones through its
digitally-switched long distance network.

PhoneTel Technologies, Inc. operates a system of approximately 45,000 payphones
in 42 states and the District of Columbia.

Peoples Telephone Company, Inc. operates a system of approximately 43,000
installed payphones in 39 states and the District of Columbia and provides
value-added services to thousands of additional payphones throughout the United
States.
