entitled to receive in exchange therefor a certificate representing that number

distributions with respect thereto payable to such holder in accordance with
Section 2.03(c) hereof and any cash payable in lieu of any fractional share of
Davel Common Stock in accordance with Section 2.03(e) hereof, and the PhoneTel
Certificate so surrendered shall forthwith be canceled. In the event of a
transfer of ownership of shares of PhoneTel Common Stock which is not registered
in the transfer records of PhoneTel, a certificate representing the proper
number of shares of Davel Common Stock may be issued to a person other than the
person in whose name the PhoneTel Certificate so surrendered is registered if
such PhoneTel Certificate, if in physical form, 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
Davel Common Stock to a person other than the registered holder of such PhoneTel
Certificate or establishes to the satisfaction of Davel that such tax has been
paid or is not applicable. Until surrendered as contemplated by this Section
2.03, each PhoneTel Certificate shall be deemed at any time after the PhoneTel
Effective Time to represent only the right to receive upon such surrender that
number of whole shares of Davel Common Stock which the holder thereof has the
right to receive pursuant to the provisions of this Article II, any dividends or
other distributions payable to the holder thereof in accordance with Section
2.03(c) hereof and cash in lieu of any fractional share of Davel Common Stock in
accordance with Section 2.03(e) hereof. No interest shall be paid or shall
accrue on any cash payable to holders of PhoneTel Certificates pursuant to the
provisions of this Article II.

          (c)  No dividends or other distributions with respect to Davel Common
Stock with a record date after the PhoneTel Effective Time shall be paid to the
holder of any unsurrendered PhoneTel Certificate, if in physical form, with
respect to the shares of Davel Common Stock obtainable upon surrender thereof,
and no cash payment in lieu of a fractional share of Davel Common Stock shall be
paid to any such holder pursuant to Section 2.03(e) hereof, in each case until
the surrender of such PhoneTel Certificate in accordance with this Article II,
and all such dividends, other distributions and cash in lieu of fractional
shares of Davel Common Stock shall be paid by Davel to the Exchange Agent and
shall be included in the PhoneTel Exchange Fund only after a proper surrender of
the PhoneTel Certificate has been made. Subject to the effect of applicable
escheat or similar laws, following surrender of any such PhoneTel Certificate,
there shall be paid to the holder of the certificate representing whole shares
of Davel 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 PhoneTel Effective Time theretofore paid with respect to
such whole shares of Davel Common Stock, and the amount of any cash payable in
lieu of a fractional share of Davel Common Stock to which such holder is
entitled pursuant to Section 2.03(e) hereof, and (ii) at the appropriate payment
date, the amount of dividends or other distributions with a record date after
the PhoneTel Effective Time but prior to such surrender and with a payment date
subsequent to such surrender payable with respect to such whole shares of Davel
Common Stock.

          (d)  All shares of Davel Common Stock issued upon the surrender for
exchange of PhoneTel Certificates in accordance with the terms of this Article
II (including any cash paid in lieu of fractional shares of Davel Common Stock
pursuant to this Article II) shall be deemed to have been issued (and paid) in
full satisfaction of all rights pertaining to PhoneTel Common Stock theretofore
represented by such PhoneTel 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 PhoneTel Effective Time which may have been
declared or made by PhoneTel on such shares of PhoneTel Common Stock which
remain unpaid at the PhoneTel Effective Time, and there shall be no further
registration of transfers on the stock transfer books of the Surviving
Corporation of the shares of PhoneTel Common Stock which were outstanding
immediately prior to the PhoneTel Effective Time.  If, after the PhoneTel
Effective Time, PhoneTel 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 II, except as otherwise provided by law.

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

               (i)   Davel shall pay or cause to be paid to each former holder
     of PhoneTel 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 PhoneTel Common Stock held at the
     PhoneTel Effective Time by such holder) would otherwise be entitled by (B)
     the average of the closing bid prices on the Nasdaq OTC market during the
     ten consecutive Trading Days ending on the second Trading Day prior to the
     date of the PhoneTel Stockholders Meeting. For purposes of this Agreement,
     "Trading Day" shall mean any day on which the Nasdaq OTC market is open for
      -----------
     trading.

               (ii)  As soon as practicable after the determination of the
     amount of cash, if any, to be paid to holders of PhoneTel Certificates
     formerly representing PhoneTel Common Stock with respect to any fractional
     share interests, the Exchange Agent shall make available such amounts to
     such holders of PhoneTel Certificates formerly representing shares of
     PhoneTel Common Stock subject to and in accordance with the terms of
     Section 2.03(c) hereof.

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

                                      -6-

          (g)  None of Davel, PhoneTel or the Exchange Agent shall be liable to
any person in respect of any shares of Davel Common Stock, any dividends or
distributions with respect thereto, or any cash in lieu of fractional shares of
Davel Common Stock, in each case, delivered to a public official pursuant to any
applicable abandoned property, escheat or similar law. If any PhoneTel
Certificate in physical form shall not have been surrendered prior to the date
on which any PhoneTel Merger Consideration, any dividends or distributions
payable to the holder of such PhoneTel Certificate or any cash payable to the
holder of such PhoneTel Certificate formerly representing PhoneTel Common Stock
pursuant to this Article II would otherwise escheat to or become the property of
any Governmental Entity, any such PhoneTel Merger Consideration, dividends or
distributions in respect of such PhoneTel Certificate or any 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 PhoneTel
Exchange Fund in investment grade securities or U.S. government obligations, as
directed by Davel, on a daily basis. Any interest and other income resulting
from such investments shall be paid to Davel.

          (i)  If any PhoneTel Certificate in physical form shall have been
lost, stolen or destroyed, upon the making of an affidavit of that fact by the
person claiming such PhoneTel 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 PhoneTel
Certificate, the Exchange Agent shall issue in exchange for such lost, stolen or
destroyed PhoneTel Certificate the PhoneTel Merger Consideration and, if
applicable, any unpaid dividends and distributions on shares of Davel Common
Stock deliverable in respect thereof and any cash in lieu of any fractional
share, in each case, due to such person pursuant to this Agreement.

          Section 2.04   Certain PhoneTel Adjustments. If, after the date hereof
and on or prior to the PhoneTel Effective Time, the outstanding shares of Davel
Common Stock or PhoneTel Common Stock shall (other than as contemplated by
Article I hereof) be changed into a different number, class or series of shares
or any other security by reason of any reclassification, recapitalization,
reorganization, merger, business combination, split-up, stock split, combination
or exchange of shares, or any dividend payable in stock or other securities
shall be declared thereon with a record date within such period, or any similar
event shall occur, the Exchange Ratio (and/or the security or securities to be
issued to the holders of PhoneTel Common Stock) shall be appropriately adjusted
to provide the effects contemplated by this Agreement prior to such
reclassification, recapitalization, reorganization, merger, business
combination, split-up, stock split, combination, exchange or dividend or similar
event.

          Section 2.05   Stock Options and Warrants.

          (a)  As of the PhoneTel Effective Time, (i) each outstanding option to
purchase PhoneTel Common Stock (collectively, the "PhoneTel Options") shall be
                                                   ----------------
converted into an

                                      -7-
<PAGE>

option (an "Adjusted PhoneTel Option") to purchase the number of shares of Davel
            ------------------------
Common Stock equal to the number of shares of PhoneTel Common Stock subject to
such options immediately prior to the PhoneTel Effective Time multiplied by the
Exchange Ratio (rounded to the nearest whole number of shares of Davel Common
Stock), at an exercise price per share equal to the exercise price for each such
share of PhoneTel Common Stock subject to such option divided by the Exchange
Ratio (rounded down to the nearest whole cent), and all references in each such
option to PhoneTel shall be deemed to refer to Davel, where appropriate;
provided, however, that the adjustments provided in this clause (i) with respect
--------  -------
to any options which are "incentive stock options" (as defined in Section 422 of
the Code) or which are described in Section 423 of the Code shall be effected so
as not to constitute a modification, extension or renewal of such option under
Section 424(a) of the Code, (ii) Davel shall assume the obligations of PhoneTel
under the PhoneTel Options, (iii) each outstanding warrant to purchase PhoneTel
Common Stock (the "PhoneTel Warrants") shall be converted into a warrant (an
                   -----------------
"Adjusted PhoneTel Warrant") to purchase the number of shares of Davel Common
 -------------------------
Stock equal to the number of shares of PhoneTel Common Stock subject to such
PhoneTel Warrants immediately prior to the PhoneTel Effective Time multiplied by
the Exchange Ratio (rounded to the nearest whole number of shares of Davel
Common Stock), at an exercise price per share equal to the exercise price for
each such share of PhoneTel Common Stock subject to such PhoneTel Warrant
divided by the Exchange Ratio (rounded to the nearest whole cent), and all
references in each such PhoneTel Warrant to PhoneTel shall be deemed to refer to
Davel, where appropriate and (iv) Davel shall assume the obligations of PhoneTel
under the PhoneTel Warrants. The other terms of each Adjusted PhoneTel Option
and Adjusted PhoneTel Warrant, and the plans or agreements under which they were
issued, if any, shall continue to apply in accordance with their terms. The date
of grant of each Adjusted PhoneTel Option and Adjusted PhoneTel Warrant shall be
the date on which the corresponding PhoneTel Option or PhoneTel Warrant was
granted.

          (b)  PhoneTel and Davel agree that each of the applicable PhoneTel
equity-based compensation plans (the "PhoneTel Stock Option Plans"), programs or
                                      ---------------------------
agreements and each of the applicable Davel equity-based compensation plans (the
"Davel Stock Option Plans") shall be amended, to the extent necessary, to
 ------------------------
reflect the transactions contemplated by this Agreement, including, without
limitation, the conversion of each share of PhoneTel Common Stock held or to be
awarded or paid pursuant to such plans, programs or agreements into shares of
Davel Common Stock on a basis consistent with the transactions contemplated by
this Agreement. PhoneTel and Davel shall submit such amendments to the Davel
Stock Option Plans or such PhoneTel Stock Option Plans, programs or agreements
to their respective stockholders, if such submission is determined to be
necessary by counsel to PhoneTel or Davel after consultation with one another to
preserve the benefits of the PhoneTel Options; provided, however, that such
                                               --------  -------
approval shall not be a condition to the consummation of the Transactions. No
options or other awards shall have been made under any Davel Stock Option Plan,
including the Davel Communications, Inc. 2000 Long-Term Equity Incentive Plan
(in accordance with the following sentence, the "New Plan"), or any PhoneTel
                                                 --------
Stock Option Plan at or prior to the PhoneTel Effective Time. Pursuant to
Section 7.05 below, the New Plan shall be amended, as of the PhoneTel Effective
Time, in substantially the form attached hereto as Exhibit C (the "Amended
                                                                   -------
Plan") to increase the number of options reserved and available for grant under
----
such plan, as necessary to permit four percent (4%) of the shares of Davel
Common Stock

                                      -8-
<PAGE>

outstanding immediately after the PhoneTel Effective Time, on a fully-diluted
basis, and including all shares reserved for grant under the Amended Plan.

          (c)  As of the PhoneTel Effective Time, Davel shall (i) reserve for
issuance the number of shares of Davel Common Stock that shall become subject to
the Adjusted PhoneTel Warrants and Adjusted PhoneTel Options and (ii) issue or
cause to be issued the appropriate number of shares of Davel Common Stock
pursuant to the Adjusted PhoneTel Warrants and Adjusted PhoneTel Options, upon
the exercise or maturation of rights existing thereunder on the PhoneTel
Effective Time or as thereafter granted or awarded. No later than the PhoneTel
Effective Time, Davel shall prepare and file with the Securities and Exchange
Commission (the "SEC") a registration statement on Form S-8 (or other
                 ---
appropriate form) registering a number of shares of Davel Common Stock necessary
to fulfill Davel's obligations under this Section 2.05. Such registration
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 any Adjusted PhoneTel Options remain outstanding.

          (d)  As soon as practicable after the PhoneTel Effective Time, Davel
shall deliver to the holders of PhoneTel Options and PhoneTel Warrants
appropriate notices setting forth (i) such holders' rights pursuant to the
respective plans and agreements evidencing the grants of the related PhoneTel
Options and PhoneTel Warrants, (ii) the number of Shares of Davel Common Stock
for which such holder's Adjusted PhoneTel Options or Adjusted PhoneTel Warrants
are then exercisable and the exercise price therefor, and (iii) that such
PhoneTel Options and PhoneTel Warrants and the related plans, programs and
agreements shall be assumed by Davel and shall continue in effect on the same
terms and conditions (subject to the adjustments required by this Section 2.05
after giving effect to the PhoneTel Merger).

          Section 2.06   Dissenter's Rights.

          (a)  Any PhoneTel Common Stock as to which dissenting shareholders'
rights are perfected under Sections 1701.84 and 1701.85 of the Ohio Law
("Dissenting Shares") shall not be converted into or represent a right to
  -----------------
receive the PhoneTel Merger Consideration. Holders of Dissenting Shares shall be
entitled only to the rights of a dissenting shareholder under Section 1701.85 of
the Ohio Law, and such PhoneTel Common Stock shall be canceled and retired and
shall cease to exist.

          (b)  If the rights of any holder who has made a demand for dissenting
shareholders' rights under Section 1701.85 of the Ohio Law are terminated for
any reason other than the purchase by the Surviving Corporation or Davel of the
PhoneTel Common Stock subject to the demand, the shares subject to the demand
shall be converted into and represent only the right to receive the PhoneTel
Merger Consideration, without interest thereon, upon surrender of the
certificates representing the shares, and such shares shall be canceled and
retired and shall cease to exist.


                                      -9-
<PAGE>


          (c)  PhoneTel shall give Davel (i) prompt notice and copies of any
demands for dissenting shareholders' rights under Sections 1701.84 and 1701.85
of the Ohio Law and of any withdrawals of any such demands and (ii) the right to
direct all negotiations and proceedings with respect to any such demands.
PhoneTel shall not, except with the prior written consent of Davel, voluntarily
make any payment with respect to any such demands or any offer to settle any
such demands and PhoneTel's board of directors shall not waive any failure by
any dissenting shareholder to comply with Section 1701.85 of the Ohio Law.

          Section 2.07  PhoneTel Articles of Incorporation. The articles of
incorporation of P Sub in effect at the PhoneTel Effective Time shall, without
further action, become (and shall be specified by the PhoneTel Certificate of
Merger to be) the articles of incorporation of the Surviving Corporation until
amended in accordance with applicable law, except that the name of the Surviving
Corporation shall be "PhoneTel Technologies, Inc."

          Section 2.08  PhoneTel Code of Regulations. The code of regulations of
P Sub in effect at the PhoneTel Effective Time shall, without further action,
become (and shall be specified by the PhoneTel Certificate of Merger to be) the
code of regulations of the Surviving Corporation until amended in accordance
with applicable law.

          Section 2.09  Directors and Officers. From and after the PhoneTel
Effective Time, until successors are duly elected or appointed in accordance
with applicable law, (a) the directors of P Sub at the PhoneTel Effective Time
shall constitute all of the directors of the Surviving Corporation, and (b) the
officers of PhoneTel at the PhoneTel Effective Time shall be the officers of the
Surviving Corporation.

                                  ARTICLE III

                               THE DAVEL MERGER

          Section 3.01  Effectuation of Davel Merger.

          (a)  On the terms and subject to the conditions hereof, on the Closing
Date, the parties shall effect the Davel Merger, pursuant to which D Sub shall
be merged with and into Davel Financing in accordance with the Delaware General
Corporation Law ("Delaware Law") and with the Delaware Limited Liability Company
                  ------------
Act ("Delaware LLC Act"), whereupon the separate corporate existence of D Sub
      ----------------
shall cease, and Davel Financing shall be the surviving company (the "Davel
                                                                      -----
Financing Surviving Company"), with all of its outstanding membership interests
---------------------------
then being held by Davel.

          (b)  On the Closing Date, in order to effectuate the Davel Merger,
Davel Financing and D Sub shall file a certificate of merger with the Secretary
of State of the State of Delaware (the "Davel Financing Certificate of Merger")
                                        -------------------------------------
and make all other filings or recordings required by the Delaware Law and
Delaware LLC Act in connection with the Davel Merger. The

                                     -10-
<PAGE>

Davel Merger shall become effective at 4:59 p.m., E.S.T., on the Closing Date,
which time shall be specified as the effective time on the Davel Financing
Certificate of Merger (the "Davel Effective Time").
                            --------------------

          (c)  From and after the Davel Effective Time, the Davel Financing
Surviving Company shall possess all of the assets, rights, privileges, powers
and franchises and be subject to all of the liabilities, restrictions,
disabilities and duties of Davel Financing, all as provided by the Delaware Law
and Delaware LLC Act.

          Section 3.02  Conversion of D Sub Shares. At the Davel Effective Time,
by virtue of the Davel Merger and without any action on the part of the holders
thereof, each share (and each fractional share) of D Sub Stock outstanding
immediately prior to the Davel Effective Time shall be converted into the right
to receive fully paid and nonassessable shares of Davel Common Stock  (the
"Davel Merger Consideration") in the ratio of 380,612.73 shares of Davel Common
Stock to each share of D Sub Stock (provided that, notwithstanding the foregoing
conversion ratio, to the extent that the application of such conversion ratio to
any holder of D Sub Stock would (after aggregating all such shares, and
fractions thereof, then held by such holder and being so converted) result in
such holder being entitled to receive a fractional share of Davel Common Stock,
then such holder shall be entitled (a) to receive only the highest whole number
of shares to which such holder would be entitled (and such fractional share
shall not be issued or paid to such holder in any other form) in the case in
which such fractional share constitutes less than one-half (1/2) of a share) or
(b) to receive the sum of the highest whole number of shares to which such
holder would be entitled plus one additional share (and such fractional share
shall not be issued or paid to such holder in any other form) in the case in
which such fractional share constitutes one-half (1/2) or more of a share). Each
such share (and fractional share) of D Sub Stock so converted shall cease to be
outstanding (and shall automatically be canceled and retired and shall cease to
exist), and each holder of a certificate representing any such shares, or
fractions thereof, of D Sub Stock shall cease to have any rights with respect
thereto, except the right to receive the Davel Merger Consideration to be issued
in consideration therefor upon surrender of such certificate in accordance with
Section 3.03 hereof, without interest.

          Section 3.03  Exchange of Davel Shares.

          (a)  Pursuant to the Exchange Agent Agreement, Davel shall deposit
with the Exchange Agent prior to the Davel Effective Time, for the benefit of
the holders of shares of D Sub Stock, for exchange in accordance with this
Article III, through the Exchange Agent, certificates representing the shares of
Davel Common Stock issuable pursuant to Section 3.02 hereof in exchange for
outstanding shares, or fractions thereof, of D Sub Stock (such shares of Davel
Common Stock, together with any dividends or distributions with respect thereto
payable to such holder in accordance with Section 3.03(c) hereof being herein
referred to as the "Davel Exchange Fund").
                    -------------------

          (b)  As soon as reasonably practicable after the Davel Effective Time,
the Exchange Agent shall mail to each holder of record of a certificate or
certificates which immediately prior to the Davel Effective Time represented
outstanding shares of D Sub Stock (including any book entry in lieu thereof, the
"D Sub Certificates") whose shares of D Sub Stock, or fractions thereof,
 ------------------

                                     -11-
<PAGE>

were converted into the right to receive the Davel Merger Consideration pursuant
to Section 3.02 hereof, (i) a letter of transmittal (which shall specify that
delivery shall be effected, and risk of loss and title to the D Sub Certificates
shall pass, only upon, if applicable, delivery of the D Sub Certificates to the
Exchange Agent and shall be in such form and have such other provisions typical
in transactions of this type as Davel may reasonably specify) and (ii)
instructions for use in surrendering the D Sub Certificates, if in physical
form, in exchange for the Davel Merger Consideration, as applicable. Upon
surrender of a D Sub 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 D Sub Certificate shall be entitled to receive in exchange therefor a
certificate representing that number of shares of Davel Common Stock which such
holder has the right to receive pursuant to the provisions of this Section 3.02
hereof, together with any dividends or other distributions with respect thereto
payable to such holder in accordance with Section 3.03(c) hereof, and each D Sub
Certificate so surrendered shall forthwith be canceled. In the event of a
transfer of ownership of shares of D Sub Stock, or fractions thereof, which is
not registered in the transfer records of D Sub, a certificate representing the
proper number of shares of Davel Common Stock may be issued to a person other
than the person in whose name the D Sub Certificate so surrendered is registered
if such D Sub Certificate, if in physical form, 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
Davel Common Stock to a person other than the registered holder of such D Sub
Certificate or establishes to the satisfaction of Davel that such tax has been
paid or is not applicable. Until surrendered as contemplated by this Section
3.03, each D Sub Certificate shall be deemed at any time after the Davel
Effective Time to represent only the right to receive upon such surrender that
number of shares of Davel Common Stock which the holder thereof has the right to
receive pursuant to the provisions of this Article III and any dividends or
other distributions payable to the holder thereof in accordance with Section
3.03(c) hereof. No interest shall be paid or shall accrue on any cash payable to
holders of D Sub Certificates pursuant to the provisions of this Article III.

          (c)  No dividends or other distributions with respect to D Sub Stock
with a record date after the Davel Effective Time shall be paid to the holder of
any unsurrendered D Sub Certificate, if in physical form, with respect to the
shares of D Sub Stock represented thereby, and all such dividends and other
distributions shall be paid by Davel to the Exchange Agent and shall be included
in the Davel Exchange Fund, in each case, until the surrender of such D Sub
Certificate in accordance with this Article III. Subject to the effect of
applicable escheat or similar laws, following surrender of any such D Sub
Certificate, there shall be paid to the holder of the certificate representing
shares of Davel 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 Davel Effective Time theretofore paid with respect
to such whole shares of Davel Common Stock, and (ii) at the appropriate payment
date, the amount of dividends or other distributions with a record date after
the Davel Effective Time but prior to such surrender and with a payment date
subsequent to such surrender payable with respect to such whole shares of Davel
Common Stock.

          (d)  All shares of Davel Common Stock issued upon the surrender for
exchange of D Sub Certificates in accordance with the terms of this Article III
shall be deemed to

                                     -12-
<PAGE>

have been issued (and paid) in full satisfaction of all rights pertaining to
shares (or fractional shares) of D Sub Stock theretofore represented by such D
Sub Certificates, subject, however, to the Davel Financing Surviving Company's
obligation to pay any dividends or make any other distributions with a record
date prior to the Davel Effective Time which may have been declared or made by
Davel Financing on such shares, or fractional shares, of D Sub Stock which
remain unpaid at the Davel Effective Time, and there shall be no further
registration of transfers on the stock transfer books of the Davel Financing
Surviving Company of D Sub Stock which were outstanding immediately prior to the
Davel Effective Time. If, after the Davel Effective Time, D Sub Certificates are
presented to the Davel Financing Surviving Company or the Exchange Agent for any
reason, they shall be canceled and exchanged as provided in this Article III,
except as otherwise provided by law.

          (e)  Any portion of the Davel Exchange Fund which remains
undistributed to the holders of the D Sub Certificates six months after the
Closing Date shall be delivered to Davel, upon demand, and any holders of the D
Sub Certificates who have not theretofore surrendered their D Sub Certificates
in accordance with this Article III shall thereafter look only to Davel for
payment of their claims for Davel Merger Consideration and any dividends or
distributions with respect to Davel Common Stock.

          (f)  None of Davel, D Sub or the Exchange Agent shall be liable to any
person in respect of any shares of Davel Common Stock, any dividends or
distributions with respect thereto, in each case, delivered to a public official
pursuant to any applicable abandoned property, escheat or similar law. If any D
Sub Certificate in physical form shall not have been surrendered prior to the
date on which any Davel Merger Consideration, any dividends or distributions
payable to the holder of such D Sub Certificate or any cash payable to the
holder of such D Sub Certificate formerly representing D Sub Stock pursuant to
this Article III would otherwise escheat to or become the property of any
Governmental Entity, any such Davel Merger Consideration, dividends or

                                  ARTICLE IV

                  REPRESENTATIONS AND WARRANTIES OF PHONETEL

          PhoneTel represents and warrants to Davel that:

          Section 4.01  Corporate Organization. PhoneTel is a corporation duly
organized, validly existing and in good standing under the laws of the State of
Ohio, and has all requisite corporate power and authority to own, operate and
lease its properties and assets and to carry on its business as it is now being
conducted. Except as set forth in Section 4.01 of the disclosure letter
delivered by PhoneTel to Davel with the execution of this Agreement (the
"PhoneTel Disclosure Letter"), PhoneTel is duly qualified to do business and is
in good standing 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, except where the failure to be so qualified or to be in
good standing would not, individually or in the aggregate, have a PhoneTel
Material Adverse Effect. As used herein, "PhoneTel Material Adverse Effect"
shall mean a material adverse effect on the ability of PhoneTel to consummate
the Transactions or, as a result of any event, change, circumstance or effect
arising from or having an impact on PhoneTel's business, assets, financial
condition or results of operations, a material adverse effect on the ability of
Davel and its stockholders to realize substantially all of the benefits of the
Transactions.

          Section 4.02  Authorization. PhoneTel has the necessary corporate
power and authority to enter into this Agreement and, subject to the approval of
the Transactions, including, but not limited to, the PhoneTel Restructuring, the
PhoneTel Merger and this Agreement (and the transactions and amendments, if any,
to its charter documents contemplated hereby) by the affirmative vote of the
holders of a majority of the outstanding shares of PhoneTel Common Stock on the
applicable record date at the PhoneTel Stockholders Meeting ("PhoneTel
Stockholder Approval"), to carry out its obligations hereunder. The execution
and delivery of this Agreement by PhoneTel, the performance by PhoneTel of its
obligations hereunder and the consummation by PhoneTel of the Transactions have

                                     -14-
<PAGE>

been duly and validly authorized by PhoneTel's Board of Directors, have been
unanimously approved by the PhoneTel Board of Directors prior to Davel becoming
an "interested shareholder" (as defined in Section 1704.01(C)(8) of Ohio Law)
and have been approved by PhoneTel's Board of Directors as otherwise required by
PhoneTel's articles of incorporation. Except for PhoneTel Stockholder Approval,
no other corporate proceeding on the part of PhoneTel is necessary for the
execution and delivery of this Agreement by PhoneTel, the performance by
PhoneTel of its obligations hereunder or the consummation by PhoneTel of the
Transactions. This Agreement has been duly and validly executed and delivered by
PhoneTel and is a legal, valid and binding obligation of PhoneTel, enforceable
against PhoneTel in accordance with its terms, except as such enforceability may
be limited by applicable bankruptcy, insolvency, moratorium, reorganization or
other laws affecting creditors' rights generally or by the availability of
equitable remedies generally.

          Section 4.03  Capital Stock.  The authorized capital stock of PhoneTel
consists of 45,000,000 shares of PhoneTel Common Stock, of which 10,189,684
shares were issued and outstanding and no shares are held in PhoneTel's
treasury. All of the outstanding shares of capital stock of PhoneTel have been
validly issued and are fully paid, nonassessable and free of preemptive rights
with no personal liability attaching to the ownership thereof. Except for (i)
options to acquire up to 345,000 shares of PhoneTel Common Stock and (ii)
warrants to acquire up to 1,077,024 shares of PhoneTel Common Stock, there are
no outstanding subscriptions, options, warrants, rights, contracts or other
arrangements or commitments obligating PhoneTel to issue any shares of its
capital stock or any securities convertible into or exchangeable for shares of
its capital stock. Section 4.03 of PhoneTel's Disclosure Letter sets forth a
list of each PhoneTel Option and PhoneTel Warrant to issue shares of PhoneTel
Common Stock outstanding on the date hereof, together with each such option or
warrant's term, exercise price, the number of shares subject thereto and, as
applicable, the name of the PhoneTel Stock Option Plan under which such PhoneTel
Option or PhoneTel Warrant was granted.

          Section 4.04  Subsidiaries. Section 4.04 of the PhoneTel Disclosure
Letter lists all direct and indirect subsidiaries of PhoneTel (each, a "PhoneTel
Subsidiary" and, collectively, the "PhoneTel Subsidiaries").  Except for the
PhoneTel Subsidiaries and as listed in Section 4.04 of the PhoneTel Disclosure
Letter, PhoneTel does not directly or indirectly own any interest in any other
corporation, partnership, joint venture or other business association or entity.
Each PhoneTel Subsidiary is a corporation duly organized, validly existing and
in good standing under the laws of the jurisdiction of its incorporation and has
all requisite corporate power and authority to own, operate and lease its
properties and assets and to carry on its business as it is now being conducted.
Except as set forth in Section 4.04 of the PhoneTel Disclosure Letter, each
PhoneTel Subsidiary is duly qualified to do business and is in good standing 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, except
where the failure to be so qualified or to be in good standing would not,
individually or in the aggregate, be reasonably expected to have a PhoneTel
Material Adverse Effect. Except as set forth in Section 4.04 of the PhoneTel
Disclosure Letter, all outstanding shares of capital stock of each PhoneTel
Subsidiary are validly issued, fully paid and nonassessable and are owned by
PhoneTel or another PhoneTel Subsidiary free and clear of any liens, claims or
encumbrances.

          Section 4.05  Consents and Approvals; No Violation. Except as set
forth in Section 4.05 of the PhoneTel Disclosure Letter and except for (a)
applicable requirements of the Securities Exchange Act of 1934, as amended, and
the rules and regulations thereunder (the "Exchange Act"), including the filing
with and clearing by the SEC of a joint proxy statement relating to the PhoneTel
Stockholders Meeting and the Davel Stockholders Meeting, as amended or
supplemented from time to time (the "Proxy Statement"), (b) the filing of the
PhoneTel Certificate of Merger as required by Ohio Law, (c) such filings and
consents as may be required under any environmental law pertaining to any
notification, disclosure or required approval triggered by the Transactions, (d)
filings with the SEC with respect to the deregistration of the shares of
PhoneTel Common Stock and (e) such consents, approvals, orders, authorizations,
notifications, registrations, declarations and filings as may be required by
state public utility or public service commissions or under the corporation,
takeover or blue sky laws of various states, no filing with or prior notice to,
and no permit, authorization, consent or approval of, any Federal, state, local,
foreign or other governmental department, commission, board, bureau, agency or
instrumentality (each, a "Governmental Entity") is necessary for the
consummation by PhoneTel of the Transactions. Neither the execution and delivery
of this Agreement by PhoneTel nor the consummation by PhoneTel of the
Transactions, nor compliance by PhoneTel with any of the provisions hereof, will
(i) conflict with or result in any violation of any provision of the articles of
incorporation or bylaws, or comparable organizational documents, of PhoneTel or
any PhoneTel Subsidiary, (ii) except as set forth in Section 4.05 of the
PhoneTel Disclosure Letter, result in a violation or breach of, or constitute
(with or without due notice or lapse of time or both) a default (or give rise to
any right of termination, cancellation or acceleration) under, any note, bond,
mortgage, indenture, license, agreement or other instrument or obligation to
which PhoneTel or any PhoneTel Subsidiary is a party or by which any of them or
any of their properties or assets may be bound, or, (iii) subject to the
governmental filings and other matters referred to above in this Section 4.05,
violate any Federal, state, local or foreign order, writ, injunction, decree,
statute, rule or regulation applicable to PhoneTel, any PhoneTel Subsidiary or
any of their properties or assets, excluding from the foregoing clauses (ii) and
(iii) violations, breaches or defaults which, either individually or in the
aggregate, would not reasonably be expected to have a PhoneTel Material Adverse
Effect or impair materially PhoneTel's ability to perform its obligations
hereunder or prevent or materially delay the consummation of the Transactions.
The Ohio Control Share Acquisition Act (Section 1701.831et seq. of the Ohio Law)
does not apply to the execution and delivery of this Agreement or the
consummation of the Transactions.

          Section 4.06  SEC Reports and Financial Statements.

          (a)  Since November 17, 1999, PhoneTel has filed all required forms,
reports and documents with the SEC required to be filed by it pursuant to the
Securities Act of 1933, as amended, and the rules and regulations promulgated
thereunder (the "Securities Act") and the Exchange Act (hereinafter collectively
                 --------------
referred to as the "PhoneTel Reports"), all of which have complied in all
                    ----------------
material respects with all applicable requirements of the Securities Act and the
Exchange Act.

          (b)  None of the PhoneTel Reports, including, without limitation, any
financial statements or schedules included therein, at the time filed, contained
any untrue statement of a material fact or omitted to state a material fact
required to be stated therein or necessary in order

                                     -16-
<PAGE>

to make the statements therein, in light of the circumstances under which they
were made, not misleading.

          (c)  The consolidated balance sheets and the related consolidated
statements of operations, stockholders' equity and changes in financial position
(including, without limitation, the related notes thereto) of PhoneTel and the
PhoneTel Subsidiaries included in the financial statements contained in
PhoneTel's Annual Report on Form 10-K for the year ended December 31, 2000 (the
"PhoneTel 10-K") and in PhoneTel's Quarterly Report on Form 10-Q for the quarter
 -------------
ended September 30, 2001 present fairly the consolidated financial position of
PhoneTel and the PhoneTel Subsidiaries as of their respective dates, and the
results of consolidated operations and changes in consolidated financial
position for the periods then ended, all in conformity with generally accepted
accounting principles ("GAAP") applied on a consistent basis, except as
                        ----
otherwise noted therein, and subject in the case of unaudited interim financial
statements to normal year-end audit adjustments and the absence of footnotes.

          Section 4.07  Absence of Undisclosed Liabilities. Neither PhoneTel nor
any PhoneTel Subsidiary has any liabilities (whether absolute, accrued or
contingent), except: (a) liabilities, obligations or contingencies that are
accrued and reserved against in the consolidated balance sheet of PhoneTel and
the PhoneTel Subsidiaries as of December 31, 2000 or reflected in the notes
thereto, (b) liabilities incurred since December 31, 2000 in the ordinary course
of business, (c) liabilities disclosed in Section 4.07 of the PhoneTel
Disclosure Letter, (d) any liabilities which, individually or in the aggregate,
have not had, and would not reasonably be expected to have, a PhoneTel Material
Adverse Effect or (e) liabilities relating to or arising from the Servicing
Agreement or PhoneTel's performance thereof.

          Section 4.08  Changes. Since the date of the PhoneTel 10-K, and except

stock of PhoneTel (other than pursuant to the exercise of options and warrants
pursuant to their terms), or any granting to any person of any option to
purchase or other right to acquire shares of capital stock of PhoneTel or any
stock split or other change in PhoneTel's capitalization, or any repricing or
other modification to the terms of any such option or right to acquire;

          (c)  neither PhoneTel nor any PhoneTel Subsidiary has entered into or
agreed to enter into any new or amended contract with any labor unions
representing employees of PhoneTel or any PhoneTel Subsidiary;

                                     -17-
<PAGE>

               (d)  neither PhoneTel nor any PhoneTel Subsidiary has entered
into or agreed to enter into any new or amended contract with any of the
officers thereof or otherwise increased the compensation payable to the officers
or directors of any such entity;

               (e)  neither PhoneTel nor any PhoneTel Subsidiary has (i) entered
into or amended any bonus, incentive compensation, deferred compensation, profit
sharing, retirement, pension, group insurance or other benefit plan except as

except for contributions specifically required by law or pursuant to the terms
of such plans; and

               (f)  neither PhoneTel nor any PhoneTel Subsidiary has made any
change in accounting methods, principles or practices materially and adversely
affecting its assets, liabilities or business.

Section 4.09   Investigations; Litigation.

               (a)  Except as described in Section 4.09(a) of the PhoneTel
Disclosure Letter, there are no pending or, to the knowledge of PhoneTel,
threatened investigations, reviews or inquiries by any Governmental Entity with
respect to PhoneTel or any PhoneTel Subsidiary or with respect to the activities
of any officer, director or, to the knowledge of PhoneTel, employee of PhoneTel
(an "Investigation"), other than Investigations which, if the resolution thereof
     -------------
were adverse, would not, individually or in the aggregate, reasonably be
expected to have a PhoneTel Material Adverse Effect. For the purpose of this
Agreement, "knowledge of PhoneTel" shall be deemed to mean the actual knowledge,
            ---------------------
after reasonable inquiry, of John D. Chichester or Richard P. Kebert.

               (b)  Except as described in Section 4.09(b) of the PhoneTel
Disclosure Letter, (i) there are no actions or proceedings pending or, to the
knowledge of PhoneTel, threatened against PhoneTel or any PhoneTel Subsidiary
before any court or before any administrative agency or administrative officer
or executive, whether Federal, state, local or foreign, which seek to enjoin the
PhoneTel Merger or which, if adversely determined, would, individually or in the
aggregate, reasonably be expected to have a PhoneTel Material Adverse Effect,
(ii) there are no outstanding domestic or foreign judgments, decrees or orders
against PhoneTel or any PhoneTel Subsidiary that, individually or in the
aggregate, would reasonably be expected to have a PhoneTel Material Adverse
Effect, (iii) neither PhoneTel nor any PhoneTel Subsidiary is in violation of,
and none of them has received any claim or notice that it is in violation of,
any Federal, state, local or foreign laws, statutes, rules, regulations or

violations, individually or in the aggregate, would reasonably be expected to
have a PhoneTel Material Adverse Effect; and (iv) there are no actions pending
or, to the knowledge of PhoneTel, threatened against the directors or any
director of PhoneTel alleging a breach of such directors' or director's
fiduciary duties (except such actions which may arise as a result of the
Transactions).

Section 4.10   Contracts and Commitments.

               (a)  Except as are attached as exhibits to any Filed PhoneTel
Report or as set forth in Section 4.10 of the PhoneTel Disclosure Letter,
PhoneTel is not, nor is any PhoneTel

<PAGE>

Subsidiary, with respect to its business, a party to any contracts or agreements
(other than site location agreements between PhoneTel or a PhoneTel Subsidiary
(the "PhoneTel Site Location Agreements") and location providers (the "Location
      ---------------------------------                                --------
Owners")) that are material to the business, properties, assets or financial
------
condition of PhoneTel and the PhoneTel Subsidiaries, either individually or
taken as a whole (together with all amendments, exhibits, attachments, waivers
or other changes thereto, the "PhoneTel Contracts").
                               ------------------

               (b)  PhoneTel has supplied or made available to Davel valid
copies of all PhoneTel Contracts and PhoneTel Site Location Agreements.

               (c)  Since January 1, 2001, except as set forth in Section 4.10
of the PhoneTel Disclosure Letter, PhoneTel has not altered its payment
practices with regard to amounts payable to local exchange carriers in respect
of payphone services or with regard to amounts payable to Location Owners in
respect of commissions, which alteration would result in a material breach of
the contractual duties of PhoneTel to such local exchange carriers in the
aggregate or to such Location Owners in the aggregate.

Section 4.11   Environmental Matters. Except as described in the Filed PhoneTel
Reports, (a) PhoneTel and each of the PhoneTel Subsidiaries are in compliance
with all applicable Federal, state, local and foreign laws and regulations and
all judicial and administrative orders and determinations relating to pollution
or protection of the environment or of human health (including, without
limitation, ambient air, surface water, ground water, land surface or subsurface
strata) (collectively, "Environmental Laws"), except for non-compliance that
would not, individually or in the aggregate, reasonably be expected to have a
PhoneTel Material Adverse Effect, which compliance includes, but is not limited
to, the possession by PhoneTel and each of the PhoneTel Subsidiaries of permits
and other governmental authorizations required under applicable Environmental
Laws, and compliance with the terms and conditions thereof; (b) neither PhoneTel
nor any of the PhoneTel Subsidiaries has received written notice of, or, to the
knowledge of PhoneTel, is the subject of, any actions, causes of action, claims,
investigations, demands or notices by any person alleging liability under or
non-compliance with any Environmental Law that would, individually or in the
aggregate, reasonably be expected to have a PhoneTel Material Adverse Effect;
and (c) there has not been by PhoneTel or any of the PhoneTel Subsidiaries any
treatment, storage, disposal or release of any hazardous or toxic material,
substance or waste or of petroleum, or any fractions or by-products thereof, at
any of their current or, to the knowledge of PhoneTel, former properties or
facilities or any current or, to the knowledge of PhoneTel, former offsite
properties and facilities used in the business of PhoneTel or the PhoneTel
Subsidiaries (in each case, other than properties or facilities where payphones
are located pursuant to PhoneTel Site Location Agreements) in a manner or at
levels that require or is reasonably likely to require investigation, removal or
remediation under Environmental Laws that would, either individually or in the
aggregate, reasonably be expected to have a PhoneTel Material Adverse Effect.

Section 4.12   Taxes. Each of PhoneTel and the PhoneTel Subsidiaries has filed
all tax returns and reports required to be filed by it and all such returns and
reports are complete and correct in all materials respects, or requests for
extensions to file such returns or reports have been timely filed, granted and
have not expired, except to the extent that such failures to file, to be
complete or

                                     -19-
<PAGE>

correct or to have extensions granted that remain in effect individually or in
the aggregate would not reasonably be expected to have a PhoneTel Material
Adverse Effect. Each of PhoneTel and the PhoneTel Subsidiaries has timely paid
(or PhoneTel has paid on its behalf) all taxes that have become due and payable,
except to the extent the failure to pay such taxes individually or in the
aggregate would not reasonably be expected to have a PhoneTel Material Adverse
Effect, and the most recent financial statements contained in the PhoneTel
Reports reflect an adequate provision in accordance with GAAP for all taxes
payable by PhoneTel and the PhoneTel Subsidiaries for all taxable periods and
portions thereof accrued through the date of such financial statements. No
taxing authority has given written notice of any proposal, assertion or
assessment of any tax deficiencies against PhoneTel or any of the PhoneTel
Subsidiaries that are not adequately reserved for, except for deficiencies that
individually or in the aggregate would not reasonably be expected to have a
PhoneTel Material Adverse Effect. There is no action, suit, taxing authority
proceeding or audit now in progress, pending, or, to the knowledge of PhoneTel,
threatened against or with respect to PhoneTel or any of the PhoneTel
Subsidiaries.

Section 4.13   Employment Agreements. Except as disclosed in Section 4.13 of the
PhoneTel Disclosure Letter, there are no employment, consulting, severance or
indemnification contracts or agreements between PhoneTel or any PhoneTel
Subsidiary, on the one hand, and any directors, officers or other employees of
PhoneTel or any PhoneTel Subsidiary, on the other hand. PhoneTel is not a party
to any collective bargaining agreement.

Section 4.14   Change of Control Provisions. Except as disclosed in Section 4.14
of the PhoneTel Disclosure Letter, none of the contracts or agreements set forth
in Section 4.13 of the PhoneTel Disclosure Letter and none of PhoneTel's or any
PhoneTel Subsidiary's employee benefit plans, programs or arrangements contains
any provision that would become operative as the result of a change of control
of PhoneTel or that would become operative as a result of the PhoneTel Merger or
the Transactions.

Section 4.15   Employee Benefit Plans.

               (a)  Except as set forth in Section 4.15(a) of the PhoneTel
Disclosure Letter, all of the (i) Plans 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
PhoneTel or any of the PhoneTel Subsidiaries or to which PhoneTel or any of the
PhoneTel Subsidiaries is a party may be terminated by the Surviving Corporation
following the PhoneTel Effective Time without financial penalty or premium and
there shall be no obligation of the Surviving Corporation or Davel following the
PhoneTel Effective Time to issue any shares of their respective capital stock
pursuant to any of the foregoing or otherwise following the PhoneTel Effective
Time. Except as set forth in Section 4.15(a) of the PhoneTel Disclosure Letter,
no payment by PhoneTel or any of the PhoneTel Subsidiaries to any person
(payable or distributable pursuant to the foregoing agreements and plans or this
Agreement) shall be nondeductible by PhoneTel or any of the PhoneTel
Subsidiaries for Federal income tax purposes because of Section 280G of the
Code.

               (b)  Since December 31, 2000, all employee benefit plans within
the meaning of Section 3(3) of the Employment Retirement Income Security Act of
1974, as amended
                                     -20-
<PAGE>

("ERISA"), maintained by PhoneTel or any of the PhoneTel Subsidiaries
  -----
(collectively, the "Plans") are in material compliance with, and have been
                    -----
administered and operated 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 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 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 the payment
of contributions and benefits in the ordinary course). 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 risk of termination or partial
termination of any Plan which could reasonably be anticipated to result in
liability on the part of PhoneTel or any of the PhoneTel Subsidiaries. Full
payment has been made, or provision has been made therefor, of all amounts which
PhoneTel or any of the PhoneTel 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
PhoneTel nor any of the PhoneTel Subsidiaries nor, to the knowledge of PhoneTel,
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 PhoneTel, any of the PhoneTel Subsidiaries, or any
officer, director, employee of PhoneTel or any of the PhoneTel Subsidiaries or,
to the knowledge of PhoneTel, any trustee, administrator or other fiduciary of
any Plan, would be subject to either a penalty pursuant to Section 502(i) of
ERISA or a material tax imposed by Section 4975 of the Code nor, to the
knowledge of PhoneTel, shall the consummation of the Transactions constitute
such a transaction. Except as disclosed in Section 4.15(b) of the PhoneTel
Disclosure Letter, no claim, action or litigation, has been made, commenced or,
to the knowledge of PhoneTel, threatened with respect to any Plan (other than
claims for benefits made in the ordinary course). No Plan or related trust owns
any securities in violation of Section 407 of ERISA. No withdrawal by PhoneTel
or any of the PhoneTel 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 PhoneTel. 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.
PhoneTel has paid, or has set up an adequate reserve for, all liabilities under
each Plan.

Section 4.16   Licenses. PhoneTel and the PhoneTel 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 PhoneTel and the PhoneTel Subsidiaries taken as a whole. All such
Licenses are in full force and effect and, to the knowledge of PhoneTel, will
not be impaired or adversely affected by the Transactions in a manner or to a
degree that would reasonably be expected


                                     -21-
<PAGE>

to have a PhoneTel Material Adverse Effect. There is not pending or, to the
knowledge of PhoneTel, threatened any domestic or foreign suit or proceeding

                                   OF DAVEL

                Davel represents and warrants to PhoneTel that:

own, operate and lease its properties and assets and to carry on its businesses
as now being conducted. Except as set forth in Section 5.01 of the disclosure
letter delivered by Davel to PhoneTel concurrently with the execution of this
Agreement (the "Davel Disclosure Letter"), Davel and P Sub are duly qualified to
do business and are in good standing in each jurisdiction in which the character
of their properties owned or held under lease or the nature of their activities
makes such qualification necessary except where the failure to be so qualified
or to be in good standing would not, individually or in the aggregate, have a
Davel Material Adverse Effect. As used herein, "Davel Material Adverse Effect"
shall mean a material adverse effect on the ability of Davel to consummate the
Transactions or, as a result of any event, change, circumstance or effect
arising from or having an impact on Davel's business, assets, financial
condition or results of operations, a material adverse effect on the ability of
PhoneTel and its stockholders to realize substantially all of the benefits of
the Transactions.

Section 5.02   Authorization. Each of Davel and P Sub has the necessary

Common Stock on the applicable record date

duly and validly authorized by the respective Boards of Directors of Davel and P
Sub, have been approved by the Boards of Directors of Davel and P Sub as
otherwise required by their respective articles of incorporation or comparable
organizational documents, and have been approved by Davel as the sole
stockholder of P Sub. Except for Davel Stockholder Approval, no other corporate
proceeding on the part of Davel or P Sub is necessary for the execution and
delivery of this Agreement by Davel and P Sub, the performance of their
obligations hereunder and the consummation by Davel and P Sub of the
Transactions. This Agreement has been duly and validly executed and delivered by
Davel and P Sub and is a legal, valid and binding obligation of Davel and P Sub,

enforceability may be limited by applicable bankruptcy, insolvency, moratorium,
reorganization or other laws affecting creditors' rights generally or by the

securities convertible into or exchangeable for shares of its capital stock.
Section 5.03 of Davel's Disclosure Letter sets forth a list of each Davel Option
and Davel Warrant to issue shares of Davel Common Stock outstanding on the date
hereof, together with each such Davel Option or Davel Warrant's term, exercise
price, and the number of shares subject thereto, and as applicable, the name of

Section 5.04 of the Davel Disclosure Letter, each Davel Subsidiary is duly
qualified to do business and is in good standing 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, except where the failure to be so
qualified or to be in good standing would not, individually or in the aggregate,
be reasonably expected to have a Davel Material Adverse Effect. Except as set
forth in Section 5.04 of the Davel Disclosure Letter, all outstanding shares of
capital

and delivery of this Agreement by Davel or P Sub, nor the consummation by Davel
or P Sub of the Transactions nor compliance by Davel or P Sub with any of the
provisions hereof, will (i) conflict with or result in any violation of any
provision of the articles of incorporation or bylaws, or comparable
organizational documents, of Davel or any Davel Subsidiary, (ii) at the Davel
Effective Time, result in a violation or breach of, or constitute (with or

which Davel or any Davel Subsidiary is a party or by which any of them or any of

the Davel Effective Time, to issue any shares of its capital stock pursuant to
any of the foregoing or otherwise following the Davel Effective Time. Except as
set forth in Section 5.15(a) of the Davel Disclosure Letter, no payment by Davel
or any of the Davel Subsidiaries to any person (payable or distributable
pursuant to the foregoing agreements and plans or this Agreement) shall be
nondeductible by Davel or any of the Davel Subsidiaries for Federal income tax
purposes because of Section 280G of the Code.

          (b)  Since December 31, 2000, all employee benefit plans within the
meaning of Section 3(3) of ERISA maintained by Davel or any of the Davel
Subsidiaries (collectively, the "Davel Benefit Plans") are in material
                                 -------------------
compliance with, and have been administered and operated in accordance with, the
terms of such Davel Benefit Plans and applicable law, and the Internal Revenue
Service has determined that each such Davel Benefit Plan which is intended to be
"qualified" within the meaning of Section 401(a) of the Code 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
has occurred and is continuing with respect to any Davel Benefit Plan subject to
Title IV of ERISA. No material liability under any statutes, orders,
governmental rules or regulations applicable to any Davel Benefit Plan,
including, without limitation, ERISA and the Code, has been or may reasonably be
expected to be incurred with respect to any Davel Benefit Plan (other than
liabilities for the payment of contributions and benefits in the ordinary
course). No Davel Benefit Plan has been terminated pursuant to Title IV of
ERISA. No event has occurred and no condition exists with respect to any Davel
Benefit Plan which presents a risk of termination or partial

                                     -30-
<PAGE>

termination of any Davel Benefit Plan which could reasonably be anticipated to
result in liability on the part of Davel or any of the Davel Subsidiaries. Full
payment has been made, or provision has been made therefor, of all amounts which
Davel or any of the Davel Subsidiaries were required under the terms of the
Davel Benefit Plans to have paid as contributions to such Davel Benefit Plans on
or prior to the date hereof and no Davel Benefit 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 Davel nor any of the Davel Subsidiaries
nor, to the knowledge of Davel, 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 Davel Benefit Plan (or its related trust) with respect to which Davel,
any of the Davel Subsidiaries, or any officer, director, employee of Davel or
any of the Davel Subsidiaries or, to the knowledge of Davel, any trustee,
administrator or other fiduciary of any Davel Benefit Plan, would be subject to
either a penalty pursuant to Section 502(i) of ERISA or a material tax imposed
by Section 4975 of the Code nor, to the knowledge of Davel, shall the
consummation of the Transactions constitute such a transaction. Except as
disclosed in Section 5.15(b) of the Davel Disclosure Letter, no claim, action or
litigation, has been made, commenced or, to the knowledge of Davel, threatened
with respect to any Davel Benefit Plan (other than claims for benefits made in
the ordinary course). No Davel Benefit Plan or related trust owns any securities
in violation of Section 407 of ERISA. No withdrawal by Davel or any of the Davel
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 Davel
Benefit Plan which is a multiemployer plan which would create a material
liability not adequately reserved against by Davel. 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. Davel
has paid, or has set up an adequate reserve for, all liabilities under each
Davel Benefit Plan.

          Section 5.16   Licenses. Davel and the Davel Subsidiaries have
obtained all Licenses material, individually or in the aggregate, to the conduct
of the business of Davel and the Davel Subsidiaries taken as a whole. All of
such Licenses are in full force and effect and, to the best of Davel's
knowledge, will not be impaired or adversely affected by the Transactions in a
manner or to a degree that would reasonably be expected to have a Davel Material
Adverse Effect. There is not pending or, to the knowledge of Davel, 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 in Section 5.16 of the Davel Disclosure Letter, no
event under the control of Davel 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 such Licenses, the loss of which would
reasonably be expected to have a Davel Material Adverse Effect.

          Section 5.17   Compliance with Other Instruments and Laws.  Except as
set forth in Section 5.17 of the Davel Disclosure Letter, neither Davel nor any
Davel Subsidiary is in violation of any term of its articles of incorporation or
bylaws or comparable organizational documents, or in violation of any Davel
Contract or of any judgment, decree or order which names Davel or any Davel
Subsidiary or in violation of any term of any other material instrument,
contract or agreement (other than any

                                     -31-
<PAGE>

Davel Site Location Agreement) to which it is a party or by which it or any of
its properties or assets is bound, except to the extent that any such violation
would not reasonably be expected to have a Davel Material Adverse Effect. Except
as set forth in Section 5.17 of the Davel Disclosure Letter, Davel's and each
Davel Subsidiary's businesses are in compliance with all Federal, state, local
and foreign statutes, laws, ordinances, rules, governmental regulations,
permits, concessions, grants, franchises, licenses or other governmental
authorizations or approvals applicable to the operation of such business, except
to the extent that the failure to be in compliance would not reasonably be
expected to have a Davel Material Adverse Effect.

          Section 5.18   Employees. Without limiting the generality of Section
5.17 hereof, Davel has complied in all material respects with all laws relating
to the employment of labor, including provisions thereof relating to wages,
hours, equal opportunity, collective bargaining, civil rights, workers
compensation, WARN statutes, severance, termination, record keeping, labor
relations and family and/or medical leave and, to the knowledge of Davel, it
does not have any material labor relations problems (including, without
limitation, actual or threatened strikes or work stoppages or material
grievances).

          Section 5.19   Information Supplied. None of the information supplied
or to be supplied by Davel for inclusion or incorporation by reference in (i)
the Form S-4 shall, at the time the Form S-4 is filed with the SEC or at the
time it becomes effective under the Securities Act, contain any untrue statement
of a material fact or omit to state any material fact required to be stated
therein or necessary to make the statements therein, in light of the
circumstances under which they were made, not misleading or (ii) the Proxy
Statement shall, at the date it is first mailed to Davel's stockholders or at
the time of the Davel Stockholders Meeting, contain any untrue statement of a
material fact or omit to state any material fact required to be stated therein
or necessary in order to make the statements therein, in light of the
circumstances under which they were made, not misleading. The Form S-4 shall
comply as to form in all material respects with the requirements of the
Securities Act, except that no representation or warranty is made by Davel with
respect to statements made or incorporated by reference in either the Form S-4
or the Proxy Statement based on information supplied by PhoneTel for inclusion
or incorporation by reference therein.

          Section 5.20   State Takeover Statutes. To the knowledge of Davel, no
"fair price," "moratorium," "control share acquisition" or other similar anti-
takeover statute or regulation enacted under state or Federal law applicable to
Davel is applicable to the Transactions.

          Section 5.21   Certain Fees. Except in connection with the engagement
of Marshall & Stevens and as otherwise set forth in Section 5.21 of the Davel
Disclosure Letter, neither Davel nor any Davel Subsidiary has employed any
broker or finder or incurred any liability for any financial advisory, brokerage
or finders' fees or commissions in connection with the Transactions. The fees
payable by Davel to Marshall & Stevens in connection with the Transactions are
set forth in Section 5.21 of the Davel Disclosure Letter.

          Section 5.22   Opinion of Financial Advisor. Davel has received the
opinion of Marshall & Stevens, dated the date hereof, attached hereto as Exhibit
F.

          Section 5.23   Voting Requirements. Except as contemplated by Article
I hereof, Davel Stockholder Approval is the only vote of the holders of any
class or series of Davel's capital stock necessary to adopt this Agreement and
approve the Transactions.

          Section 5.24   Payphones. As of January 10, 2002, Davel has good and
marketable title to at least 54,000 installed payphones, all of which, except
for those specifically described in Section 5.24 of the Davel Disclosure Letter,
are operational and which, except for those payphones further specifically
described in Section 5.24 of the Davel Disclosure Letter, are subject to
enforceable Davel Site Location Agreements with Location Owners. Davel's good
faith estimate of the average remaining term of the Davel Site Location
Agreements is 24 months.

          Section 5.25   Average Net Revenue. The Average Net Revenue is at
least $29.38 per payphone in operation by Davel and the Davel Subsidiaries as of
the date hereof.

                                                              ------------
Parties") to indemnify, to the fullest extent permitted under the applicable law
-------
of the state of incorporation of each such Indemnifying Party, each person who
was or is or becomes prior to the PhoneTel Effective Time, a director, officer
or trustee of any such entity (the "Indemnified Parties") for costs and expenses
                                    -------------------
incurred in respect of actions taken prior to and including the PhoneTel
Effective Time in connection with their duties as directors, officers or
trustees of the Indemnifying Parties (including with respect to the
Transactions) for a period of not less than six years from the PhoneTel
Effective Time; provided that, in the event any claim or claims are asserted or
                --------
made within such six-year period, all rights to indemnification in respect of
any such claim or claims shall continue until final disposition of any and all
such claims. Without limitation of the foregoing, in the event any Indemnified
Party becomes involved in such capacity in any pending or threatened action,
proceeding or investigation in connection with any matter or event, including
with respect to the Transactions, occurring prior to and including the PhoneTel
Effective Time, the Surviving Corporation, to the fullest extent permitted and
on such conditions as may be required by applicable law, shall make advances for
or reimburse such Indemnified Party for his or her legal and other out-of-pocket

directors and officers of such corporation's charter or bylaws as in effect as
of immediately prior to the PhoneTel Effective Time.

by the Indemnifying Parties' existing directors' and officers' liability
insurance. The Indemnifying Parties will maintain such insurance with policy
limits at least equal to the greater of (i) those in effect with respect to

its subsidiaries, in each case as of the date of this Agreement, and with

          Section 8.06  Preparation of the Form S-4 and the Proxy Statement. As
soon as practicable following the date of this Agreement, PhoneTel and Davel
shall jointly prepare and file with the SEC the Proxy Statement and PhoneTel and
Davel shall prepare, and Davel shall file, with the SEC the Form S-4, in which
the Proxy Statement shall be included as a prospectus. Each of PhoneTel and
Davel shall use reasonable best efforts to have the Form S-4 declared effective
under the Securities Act as promptly as practicable after such filing. PhoneTel

information relating to PhoneTel or Davel, or any of its affiliates, officers or
directors, should be discovered by PhoneTel or Davel which should be set forth

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 supplement describing such information shall be
promptly filed with the SEC and, to the extent required by law, disseminated to
the stockholders of PhoneTel and Davel.

Section 8.07   Letters of Accountants. Each of Davel and PhoneTel shall use its
reasonable best efforts to cause to be delivered to the other party two letters
from its respective independent accountants, one dated a date within two
business days before the date on which the Form S-4 shall become effective and
one dated a date within two business days before the Closing Date, each

Agreement, (b) refrain from taking any action that would render any such
representation or warranty untrue or incorrect as of such time, and (c) perform
