                      AMENDED AND RESTATED LOAN AGREEMENT


     This Amended and Restated Loan Agreement (this "Agreement") is entered
into by and between Davel Communications Group, Inc., an Illinois corporation
("Borrower") and The Boatmen's National Bank of St. Louis, a national banking
association ("Lender").

                                   Preamble

     Prior to the date hereof, Borrower and Lender entered into a Loan
Agreement dated as of September 30, 1994 (the "Prior Loan Agreement"), pursuant
to which Lender extended a revolving credit facility to Borrower in the amount
of $15,000,000 (as the same may have been renewed, extended, amended,
rearranged, restructured, refinanced, restated, replaced or otherwise modified
from time to time, the "Prior Revolving Loan"), which was evidenced by a
revolving note in said amount (the "Prior Revolving Note"), up to $10,000,000 of
which was convertible to a term credit facility (as the same may have been
renewed, extended, amended, rearranged, restructured, refinanced, restated,
replaced or otherwise modified from time to time, the "Prior Term Loan";
together with the Prior Revolving Loan, the "Prior Loans"), which was evidenced
by a term note in said amount (the "Prior Term Note;" together with the Prior
Revolving Note, the "Prior Notes").

     Borrower has requested that Lender restructure and refinance and
increase the Prior Loans as described in this Agreement. Lender is willing to
restructure, refinance, and increase the Prior Loans upon and subject to certain
terms and conditions to which Borrower has agreed and which are fully contained
herein.

     This Agreement amends and restates (and the Borrower expressly states
that it does not constitute an extinguishment or novation of) the Prior Loan
Agreement, the Prior Revolving Loan, the Prior Term Loan, the Prior Revolving
Note and the Prior Term Note. This Agreement and each document executed in
connection herewith evidences or effects a restructuring and refinancing of the
Prior Revolving Loan and the Prior Term Loan, and does not evidence under any
circumstances a release or relinquishment of the priority of any or all of the
Liens of Lender in any assets (real and personal) of Borrower, or a waiver of
Borrower's obligation to reimburse Lender for any amounts previously evidenced
by the Prior Revolving Note or the Prior Term Note or as otherwise set forth in
the Prior Loan Agreement and related loan documents. The loan documents executed
in connection with the Prior Loan Agreement shall be deemed amended to refer to
this Agreement and the obligations of Borrower described herein.

     In consideration of the mutual agreements herein and other sufficient
consideration, the receipt of which is hereby acknowledged, Borrower and Lender
agree as follows:

1.  General.

     1.1.  Effective Date. This Agreement shall become effective on 
September 23, 1996 (the "Effective Date").


     1.2.  Defined Terms.  Each capitalized term in this Agreement shall
have the meaning defined in the Glossary which is attached hereto as Appendix  .
If a capitalized term is not defined in the Glossary, it shall have the meaning
defined elsewhere in this
<PAGE>
 
Agreement. If a capitalized term is not defined in either the Glossary or
elsewhere in this Agreement, it shall have the meaning defined in the UCC.

     1.3.  Singular and Plural Forms.  All definitions shall be equally
applicable to both the singular and the plural forms of the terms defined.

     1.4.  References.  The words "hereof", "herein", "hereby",
"hereunder", and words of similar import refer to this Agreement as a whole and
not to any particular provision of this Agreement. The word "Section" or
"section" and "Page" or "page" refer to a section or page, respectively, of this
Agreement unless it expressly refers to something else.

     1.5.  References to Applicable Lending Office.  The term "Applicable
Lending Office" means the office of Lender at One Boatmen's Plaza, 800 Market
Street, St. Louis, Missouri 63101.

     1.6.  References to Covered Person.  The term "Covered Person"
means Borrower, and if it now has or at any time acquires any Subsidiaries that
have significant assets or operations in the reasonable determination of Lender,
each of such Subsidiaries.  The words "a Covered Person", "any Covered Person",
"each Covered Person" and "every Covered Person" refer to Borrower and each of
its Subsidiaries separately.

     1.7.  Accounting Terms with GAAP Meanings; Consolidated Basis.
Unless the context otherwise requires, accounting terms herein that are not
defined herein shall have their meanings and shall be calculated under GAAP.
All financial measurements herein respecting "Borrower" shall be made and
calculated for Borrower and all of its Subsidiaries on a consolidated basis in
accordance with GAAP.

     1.8.  "Satisfactory to Lender".  Whenever herein a document is
required to be "satisfactory to Lender", unless expressly stated otherwise such
document must be satisfactory to Lender in both form and substance. If a
document or matter is required herein to be "satisfactory to Lender", unless
expressly stated otherwise Lender shall have the absolute discretion to
determine whether the document or matter is satisfactory to Lender.

     1.9.  Computation of Time Periods.  In this Agreement, in the
computation of periods of time from a specified date to a later specified date,
the word "from" shall mean "from and including" and the words "to" and "until"
shall each mean "to but excluding."  Periods of days referred to in this
Agreement shall be counted in calendar days unless Business Days are expressly
prescribed, and references in this Agreement to months and years shall be to
calendar months and calendar years unless otherwise specified.

2.  Commitment.

     2.1. Revolving Commitment. The "Revolving Commitment" on any date shall be
an amount equal to $7,500,000 minus the Dollar amount by which it may have
otherwise been reduced as provided herein. Subject to the terms and conditions
hereof, and in reliance upon the representations and warranties of Borrower
herein, Lender commits to make advances to Borrower (each a "Revolving Advance")
from time to time during the period commencing on the Effective Date and ending
at the close of business on September 23, 2001 (the "Ultimate Revolving Maturity
Date"). (The from time to time outstanding principal balance of all Revolving
Advances from the Lender is referred to herein as the "Revolving
<PAGE>
 
Loan".)  The obligation of Borrower to repay the Revolving Loan shall
be evidenced by a promissory note payable to the order of Lender in a maximum
principal amount equal to the Revolving Commitment (the "Revolving Note")
satisfactory to Lender.  Amounts applied to reduce the Revolving Loan may be
reborrowed as Revolving Advances as provided herein, but no Revolving Advance
will be made on or after the Ultimate Revolving Maturity Date.  At any time
after an Event of Default occurs that is not waived in writing by Lender, Lender
may cancel the Revolving Commitment as provided in Section   .

          2.1.1. Limitation on Revolving Advances. No revolving Advance will be
     made which would result in the Revolving Loan exceeding the Revolving
     Commitment. Lender may, however, in its sole discretion make such Revolving
     Advances, but shall not be deemed by doing so to have increased the
     Revolving Commitment and shall not be obligated to make any such Revolving
     Advances thereafter. No Revolving Advance will be made on or after the
     Ultimate Revolving Maturity Date.

     2.2.  Convertible Revolving Commitment.  The "Convertible
Revolving Commitment" on any date shall be an amount equal to $17,500,000 minus
(i) the sum of all Term Conversions, and (ii) the Dollar amount by which it may
have otherwise been reduced as provided herein.  Subject to the terms and
conditions hereof, and in reliance upon the representations and warranties of
Borrower herein, Lender commits to make advances to Borrower (each a
"Convertible Revolving Advance") from time to time during the period commencing
on the Effective Date and ending at the close of business on September 23, 1998
(the "Ultimate Convertible Revolving Maturity Date").  (The from time to time
outstanding principal balance of all Revolving Advances from the Lender is
referred to herein as the "Convertible Revolving Loan".)  The obligation of
Borrower to repay the Convertible Revolving Loan shall be evidenced by a
promissory note payable to the order of Lender in a maximum principal amount
equal to the Convertible Revolving Commitment (the "Convertible Revolving Note")
satisfactory to Lender.  Amounts applied to reduce the Convertible Revolving
Loan may be reborrowed as Convertible Revolving Advances as provided herein, but
no Convertible Revolving Advance will be made on or after the Convertible
Ultimate Revolving Maturity Date.  At any time after an Event of Default occurs
that is not waived in writing by Lender, Lender may cancel the Convertible
Revolving Commitment as provided in Section   .

          2.2.1. Limitation on Convertible Revolving Advances. No Convertible
     Revolving Advance will be made which would result in the Convertible
     Revolving Loan exceeding the Convertible Revolving Commitment. Lender may,
     however, in its sole discretion make such Convertible Revolving Advances,
     but shall not be deemed by doing so to have increased the Convertible
     Revolving Commitment and shall not be obligated to make any such
     Convertible Revolving Advances thereafter. No Convertible Revolving Advance
     will be made on or after the Ultimate Convertible Revolving Maturity Date.

     2.3.  Term Conversions.  Subject to the terms and conditions
hereof, Lender commits to convert (each a "Term Conversion"), provided that no
Default or Event of Default exists, portions or all of the outstanding principal
amount of the Convertible Revolving Loan into term loans (each a "Conversion
Term Loan" and collectively the "Conversion Term Loans") to Borrower (the "Term
Commitment"), in one or more conversions, from time to time during the period
commencing on the Effective Date and ending at the close of Lender's 
<PAGE>
 
business at the Applicable Lending Office on the Ultimate Convertible Revolving
Maturity Date. No Term Conversion will be made which would result in the
aggregate Conversion Term Loans exceeding the Term Commitment. No Term
Conversion will be made after the Ultimate Convertible Revolving Maturity Date.
Each Term Conversion will have a repayment period of from 12 to 20 quarters (the
"Term Conversion Repayment Period"), as elected by Borrower in the applicable
Term Conversion Request, but in any event each Term Conversion will be payable
in full on the Ultimate Term Maturity Date. The obligation of Borrower to repay
each Conversion Term Loan shall be evidenced by a promissory note in
substantially the form attached hereto as Exhibit with respect to each such
Conversion Term Loan payable to the order of Lender (each a "Term Note" and
collectively, the "Term Notes"). Amounts applied to reduce any Conversion Term
Loan may not be reborrowed. The Convertible Revolving Commitment shall be
permanently reduced, on a dollar for dollar basis, by the amount of each Term
Conversion.

3.  Interest.

     3.1. Rates. The Revolving Loan, the Convertible Revolving Loan, and each
Conversion Term Loan shall bear interest at a per annum rate that is either the
Adjusted CBR or the Adjusted LIBO Rate, as designated by Borrower as provided
herein. "Adjusted CBR" shall mean the CBR plus the CBR increment. The "Adjusted
LIBO Rate" shall mean the LIBO Rate plus the LIBO increment. The "CBR increment"
and the "LIBO increment" shall be the percentage from the table below that is
adjacent to the ratio of Borrower's Funded Indebtedness (as defined in Section )
to EBITDA (as defined in Section   ) as calculated at the end of each fiscal
quarter of Borrower ending each March 31, June 30, September 30 and December 31
for the entire 12 month period then ended and shall be adjusted, if necessary,
effective the first calendar day of each June, September, December and March.

<TABLE>
<CAPTION> 
============================================================

 Indebtedness to EBITDA      CBR increment   LIBOR increment

 2.50 to 1.00                
------------------------------------------------------------

</TABLE>

The LIBOR Increment for each LIBOR Loan shall be determined quarterly, but shall
not be effective as to any existing LIBOR Loan until and unless it is renewed as
a LIBOR Loan.

The CBR Increment for each CBR Loan shall be determined quarterly, and shall
become effective for all CBR Loans immediately.

If Borrower does not deliver its Financial Statements to Lender within the
period required by this Agreement, and such failure continues for 2 Business
Days after notice from Lender, the highest possible CBR Increment and LIBOR
Increment shall become applicable as of the last day of such period and shall
remain applicable until Borrower delivers such Financial Statements to Lender.

     3.2. Interest Periods for LIBOR Loans. For each Loan that Borrower
designates to be a LIBOR Loan, Borrower shall select an interest period (each an
"Interest
    
<PAGE>
 
Period") to be applicable to such Loan.  The Interest Period
for a LIBOR Loan shall be either a one month, two month, three month, or six
month period; provided that:

     (i) every such Interest Period for an Advance shall commence on the date
     of the Advance;

     (ii) if any Interest Period would otherwise expire on a day of a calendar
     month which is not a Business Day, then such Interest Period shall expire
     on the next succeeding Business Day in that calendar month; provided,
     however, that if the next succeeding Business Day would be in the following
     calendar month, it shall expire on the first preceding Business Day;

     (iii) any Interest Period that begins on the last Business Day of a
     calendar month (or on a day for which there is no numerically corresponding
     day in the calendar month at the end of such Interest Period) shall end on
     the last Business Day of a calendar month; and

     (iv) no Interest Period for a Revolving Loan shall extend beyond the
     Revolver Maturity Date, no Interest Period for a Convertible Revolving Loan
     shall extend beyond the Convertible Revolver Maturity Date, and no Interest
     Period for a Term Loan shall extend beyond the Term Maturity Date.

     3.3.  Conversion of Loans.  Borrower may (i) at any time convert a Loan of
one type into a Loan of another type, or (ii) at the end of any Interest Period
for a LIBOR Loan, continue such LIBOR Loan for an additional Interest Period;
provided, however, that a LIBOR Loan may only be so converted or continued on
the last day of its Interest Period. To cause a conversion or continuation,
Borrower shall give Lender, prior to 11:00 a.m., St. Louis time, two (2)
Business Days prior to the date the conversion or continuation is to be
effective (the "Conversion Date"), a written request given in accordance with
the notice provisions of this Agreement (a "Notice of Conversion/Continuation")
(i) identifying the Loan to be converted or continued, (ii) specifying whether a
conversion or continuation is requested, (iii) in the case of a conversion,
specifying whether the Adjusted LIBO Rate or the Adjusted CBR is to be
applicable to the Loan upon the conversion, and (iv) in the case of conversion
to or continuation of a LIBOR Loan, specifying the Interest Period therefor. If
a Notice of Conversion/Continuation is not made by 11:00 a.m. St. Louis time on
the last day of the Interest Period for a Loan with a base rate for which an
Interest Period must be specified, then Borrower shall be deemed to have timely
given a Notice of Conversion/Continuation to Lender requesting to convert the
Loan to an Adjusted CBR Loan.

     3.4.  Compensation for Increase In LIBOR Loan Costs. If after the Execution
Date there is any change in any Law or in any rule, order, or guideline of any
Governmental Authority (whether or not having the force of law and whether or
not failure to comply therewith would be unlawful, and including but not limited
to any imposition or increase of reserve requirements) and as a result thereof
or as a result of compliance therewith by Lender or its parent holding company:

     (i)  Lender is subject to any tax, duty or other charge with respect to its
     LIBOR Loans or its obligation to make Advances that are LIBOR Loans, or the
     basis of taxation of payments to Lender of the principal of or interest on
     its LIBOR Loans, or its obligation to make the same, change (except for
     changes in the rate of tax on the overall net income of Lender
<PAGE>
 
     imposed by the United States or other jurisdiction in which Lender's
     principal executive office is located); or

     (ii) any reserve (including, without limitation, any imposed by the FRB),
     special deposit, compulsory loan, assessment, or similar requirement
     against assets of, deposits with or for the account of, or credit extended
     by, Lender is imposed or deemed applicable or any other condition affecting
     its LIBOR Loans or its obligation to make them is imposed on Lender or the
     London Interbank Market;

and as a result thereof there is any increase in the direct cost to Lender of
agreeing to make or making an Advance that is a LIBOR Advance or maintaining its
LIBOR Loans (except to the extent already included in the determination of the
applicable LIBO Rate), or there is a reduction in the amount received or
receivable by Lender, then Borrower shall from time to time, upon written notice
from and demand by Lender, pay to Lender, within five Business Days after the
date specified in such notice and demand, additional amounts sufficient to
compensate Lender in the amount of such increased cost.  If Lender claims
compensation under this Section, Lender shall furnish a certificate to Borrower
that states the additional amount or amounts to be paid to it hereunder and the
basis therefor.  Borrower shall have the burden of proving that any such
certificate is not correct.

     3.5. LIBOR Loan Funding Losses. Borrower shall pay to Lender upon demand an
amount sufficient to compensate Lender for all loss and expense suffered by
Lender, including but not limited to loss of profit and the cost of acquiring
funds to make or carry a LIBOR Advance or LIBOR Loan, (i) if for any reason
(other than a default by Lender) a Borrowing does not occur on the date
specified therefor in a Notice of Borrowing (whether or not withdrawn), (ii) if
any prepayment or repayment of a LIBOR Loan or conversion of a LIBOR Loan to a
Loan with a base rate other than the LIBO Rate, whether or not required hereby,
occurs on a date which is not the last day of the Interest Period therefor, or
(iii) if for any reason Borrower fails to repay a LIBOR Loan when required by
the terms of this Agreement. The minimum that Borrower shall be obligated to pay
to Lender in any such event shall be an amount equal to (x) the greater of zero
or

{[A x (B-C) x D]} OVER 360

wherein

     "A" is the Affected Principal Amount;

     "B" is the decimal equivalent of the LIBO Rate that is (or would be in the
     case of Borrower's failure to borrow after giving a Notice of Borrowing)
     payable by Borrower on such Loan;

     "C" is the decimal equivalent of the LIBO Rate that would apply to a
     hypothetical LIBOR Advance the Borrowing Date of which was on the last
     Business Day on or before the first day of the Remaining Interest Period
     and the amount and Interest Period of which were approximately equal, as
     determined by Lender, to the Affected Principal Amount and the Remaining
     Interest Period; and
<PAGE>
 
     "D" is the number of days from and including the first day of the Remaining
     Interest Period to but excluding the last day of the Remaining Interest
     Period;

plus (y) any other out-of-pocket loss or expense (including any internal
processing charge customarily charged by Lender) suffered by Lender in
liquidating deposits prior to maturity in amounts which correspond to the
Affected Principal Amount.

For purposes of this Section:

     "Affected Principal Amount" means, as applicable, (i) the principal amount
     of a LIBOR Advance that Borrower fails to take after having given a
     Revolving Advance Request; (ii) the entire principal amount of a LIBOR Loan
     that Borrower fails to repay when required by the terms of this Agreement;
     or (iii) the amount of any prepayment or repayment on a LIBOR Loan that
     occurs, or the entire principal amount of a LIBOR Loan that converts to a
     Loan with a base rate other than the LIBOR Rate, whether or not required
     hereby, on a date which is not the last day of the Interest Period
     therefor.

     "Remaining Interest Period" means, as applicable, (i) the entire Interest
     Period that would have been applicable to a Loan that Borrower fails to
     take after having given a Revolving Advance Request; (ii) a period equal in
     duration to the Interest Period of a LIBOR Loan that Borrower fails to
     repay when required by the terms of this Agreement; or (iii) if a
     prepayment or repayment on a LIBOR Loan occurs, or a LIBOR Loan converts to
     a Loan with a base rate other than the LIBOR Rate, whether or not required
     hereby, prior to the last day of the Interest Period therefor, the period
     from and including the date thereof to but excluding the last day of such
     Interest Period.

A certificate of Lender claiming compensation under this Section and setting
forth the amounts to be paid to it hereunder and the method of calculation
thereof shall be deemed and treated as prima facie correct (subject to rebuttal
by Borrower).

     3.6. Rate After Maturity. Borrower shall pay interest on a Loan after its
Maturity, and (at the option of Lender) upon all the Loans and other amounts
that are owing with respect thereto after the occurrence of an Event of Default,
at a per annum rate equal to the rate that would otherwise apply hereunder plus
4%.

     3.7. Time of Accrual. Interest shall accrue on all principal amounts
outstanding from and including the date when first outstanding to but excluding
the date when no longer outstanding. Amounts shall be deemed outstanding until
payments are applied thereto as provided herein.

     3.8. Computation. Interest shall be computed for the actual days elapsed
over a year deemed to consist of 360 days. Interest rates that are based on the
CBR shall change simultaneously with any change in the CBR and such rates shall
be effective for the entire day on which such CBR change becomes effective.

     3.9. Usury. Notwithstanding any provisions to the contrary in Section or
elsewhere in any of the Loan Documents, Borrower shall not be obligated to pay
interest at a rate which exceeds the maximum rate permitted by Law. If, but for
this Section 3.9, Borrower
<PAGE>
 
would be deemed obligated to pay interest at a rate which exceeds the maximum
rate permitted by Law, or if any of the Loan Obligations is paid or becomes
payable before its originally scheduled Maturity and as a result Borrower has
paid or would be obligated to pay interest at such an excessive rate, then (i)
Borrower shall not be obligated to pay interest to the extent it exceeds the
interest that would be payable at the maximum rate permitted by Law; (ii) any
such excess interest that has been paid by Borrower shall be refunded; and (iii)
the effective rate of interest shall be deemed automatically reduced to the
maximum rate permitted by Law.

4.  Fees.

     4.1. Non-Use Fee. Borrower shall pay to Lender a fee (the "Non-Use Fee")
calculated by applying (i) the percentage in the table below that is adjacent to
the ratio of Borrower's Funded Indebtedness (as defined in Section ) to EBITDA
(as defined in Section , as calculated at the end of each fiscal quarter of

calendar quarter beginning after the Effective Date and continuing on the first
day of each calendar quarter beginning thereafter and upon the Ultimate

on an annual percentage shall be calculated on the basis of a year deemed to
consist of 360 days and for the actual number of days elapsed.

          5.3.2. Principal. Borrower shall repay the principal of each
     Conversion Term Loan in consecutive equal quarterly installments, in a
     Dollar amount equal to a fraction the numerator of which is the initial
     principal amount of such Conversion Term Loan and the denominator of which
     is the total number of calendar quarters of the Term Conversion Repayment
     Period, beginning on the first day of the first full calendar quarter
     following the date of such Conversion Term Loan, and continuing on the
     first day of each calendar quarter thereafter, with a final installment of
     the remaining outstanding principal balance on the Ultimate Term Maturity
     Date.

     5.4.  Prepayments and Reduction of Commitments.

          5.4.1.  Voluntary.
 
               5.4.1.1. Revolving Loan. Borrower shall not be entitled to prepay
          any LIBOR Loan. Borrower may prepay the Revolving Loan and the
          Convertible Revolving Loan (provided such Loans are Adjusted CBR
          Loans) at any time without penalty. Amounts applied to reduce the
          Revolving Loan or the Convertible Revolving Loan may be reborrowed as
          Revolving Advances or Convertible Revolving Advances, respectively, as
          provided herein, but no Revolving Advance will be made on or after the
          Ultimate
<PAGE>
 
          Revolving Maturity Date and no Convertible Revolving Advance will be
          made on or after the Ultimate Convertible Revolving Maturity Date.

               5.4.1.2. Revolving Commitment. Borrower may reduce the Revolving
          Commitment or the Convertible Revolving Commitment in whole multiples
          of $100,000 at any time and from time to time, but only if (i)
          Borrower gives Lender written notice of Borrower's intention to make
          such reduction at least one Business Day prior to the effective date
          of the reduction, and (ii) Borrower makes on the effective date of the
          reduction any payment on the Revolving Loan or Convertible Revolving
          Loan required under Section as a consequence of the reduction. Any
          such reduction of the Revolving Commitment or the Convertible
          Revolving Commitment shall be permanent.

               5.4.1.3. Term Loan. Borrower shall not be entitled to prepay any
          LIBOR Loan. Borrower may wholly prepay any Conversion Term Loan
          (provided such Loans are Adjusted CBR Loans) at any time, and may make
          partial prepayments on any Conversion Term Loan in whole multiples of
          $100,000 from time to time, but only if (i) Borrower gives Lender
          written notice of Borrower's intention to make such prepayment at
          least one Business Day prior to tendering the prepayment, and (ii)
          Borrower pays any accrued interest on the amount prepaid at the time
          of such prepayment. Each partial prepayment on a Conversion Term Loan
          shall be applied to the remaining principal installments in the
          inverse order of their due dates.

               5.4.1.4. Premiums. No penalty or premium shall be payable upon
          any reduction by Borrower in the Revolving Commitment or Convertible
          Revolving Commitment. No penalty or premium shall be payable upon any
          prepayment of any Conversion Term Loan.

          5.4.2.  Mandatory.

               5.4.2.1. Over-Advances. If at any time the Revolving Loan exceeds
          the Revolving Commitment or the Convertible Revolving Loan exceeds the
          Convertible Revolving Commitment, whether as a result of an optional
          Revolving Advance or Convertible Revolving Advance by Lender as
          contemplated by Section , Section , or otherwise, Borrower shall on
          demand make a payment to Lender in the amount of the excess. Each such
          prepayment shall be applied first to reduce Adjusted CBR Loans which
          are Revolving Loans or Convertible Revolving Loans, as applicable,
          until such Loans are reduced to zero, and applied next to reduce LIBOR
          Loans which are Revolving Loans or Convertible Revolving Loans, as
          applicable, until such Loans are reduced to zero.
<PAGE>
 
               5.4.2.2.  Term Conversions. On the date of any Term Conversion,
          Borrower shall pay to Lender any accrued interest which accrued prior
          to such Term Conversion on the amount so converted.

               5.4.2.3.  Proceeds from Sales of Assets. If Borrower sells any of
          its assets in a single transaction or related series of transactions
          that are not in the ordinary course of business, Borrower shall make a
          prepayment on the Conversion Term Loans in the amount of the gross
          proceeds therefrom less reasonable selling expenses and the increment
          in federal, state and local income taxes, if any, payable as a
          consequence of any taxable gain from such sale. Borrower need not make
          such prepayment, however, unless the net proceeds from such sale or
          sales exceed an amount equal to five percent (5%) of Total Assets of
          Borrower (calculated prior to giving effect to such sale) in the
          aggregate in any Fiscal Year.

               5.4.2.4.  Proceeds from Sale of Securities. Unless otherwise
          permitted herein, if after the Execution Date Borrower issues any
          securities, or warrants or options therefor, except such as are
          subordinated in right of payment to all the Loan Obligations in a
          manner satisfactory to Lender, Borrower shall make a prepayment on the
          Conversion Term Loans promptly after such sale in an amount equal to
          the lesser of (i) the Conversion Term Loans, or (ii) fifty percent
          (50%) of the gross proceeds therefrom less reasonable brokers' and
          underwriters' fees and commissions and other reasonable issuing
          expenses. Borrower need not make such prepayment, however, as a result
          of any issuance of securities, warrants, or options provided the net
          proceeds from such issuances do not exceed $1,000,000 in the aggregate
          in any Fiscal Year ("Permitted Issuances").

               5.4.2.5.  Application of Insurance/Condemnation Proceeds. On the
          90th day after receipt by Borrower of any Insurance/Condemnation
          Proceeds in excess of $500,000, Borrower shall make a prepayment on
          the Conversion Term Loans in the amount of such Insurance/Condemnation
          Proceeds that have not, within the 90 day period following Borrower's
          receipt of such Insurance/Condemnation Proceeds, been either expended,
          or committed to be expended, by Borrower for the purpose of
          rebuilding, repairing or replacing the property for which such
          Insurance/Condemnation Proceeds were paid or for re-investment in
          Covered Persons. All amounts so committed to be expended, but not yet
          expended, by Borrower for the purpose of rebuilding, repairing or
          replacing such property or for re-investment in Covered Persons shall
          be deposited in an interest-bearing account with Lender in the name of
          Borrower (the "Proceeds Account"). Borrower hereby assigns and grants
          to Lender a security interest in any such Proceeds Account as security
          for payment and performance of the Loan Obligations. To the extent
          that Borrower provides evidence
<PAGE>
 
          satisfactory to Lender that Borrower has committed to expend funds in
          the Proceeds Account for rebuilding, repairing or replacing such
          property, Borrower may expend such funds. Any funds remaining in the
          Proceeds Account upon completion of the rebuilding, repairing or
          replacing of such property shall be applied to reduce the Conversion
          Term Loans.

     Each prepayment under this Section 5.4 that is required to be applied to
     reduce the Conversion Term Loans shall be applied to the Conversion Term
     Loans in such order as Lender determines in its sole and absolute
     discretion. If application to the Conversion Term Loans of any prepayment
     required under this Section 5.4 reduces the Conversion Term Loans to zero,
     the remaining amount of such prepayment shall be applied to reduce the
     Revolving Loan and the Revolving Commitment shall be automatically and
     permanently reduced by an equivalent amount. If application to the
     Revolving Loan of any prepayment required under this Section 5.4 reduces
     the Revolving Loan to zero, the remaining amount of such prepayment shall
     be applied to reduce the Convertible Revolving Loan and the Convertible
     Revolving Commitment shall be automatically and permanently reduced by an
     equivalent amount.

     5.5. Manner of Payments and Timing of Application of Payments.

          5.5.1.  Payment Requirement. Unless expressly provided to the contrary
     elsewhere herein, Borrower shall make each payment on the Loan Obligations
     to Lender as required under the Loan Documents in Dollars at the Applicable
     Lending Office on the date when due, without deduction, set-off or
     counterclaim.

          5.5.2.  Application of Payments. All payments received by Lender in
     immediately available funds at or before 12:00 p.m., St. Louis time, on a
     Business Day will be applied on the same day. Such payments received on a
     day that is not a Business Day or after 12:00 p.m. on a Business Day will
     be applied to the relevant Loan Obligation on the next Business Day. Except
     as otherwise expressly provided in this Agreement, Lender shall determine
     in its discretion the order and manner in which proceeds of the Collateral
     and other payments that Lender receives are applied to the Loan
     Obligations, and Borrower hereby irrevocably waives the right to direct the
     application of all payments and such proceeds. Lender shall have the
     continuing and exclusive right to apply and reverse and reapply all such
     proceeds and payments to any of the Loan Obligations.

          5.5.3.  Interest Calculation. Section notwithstanding, for purposes of
     interest calculation only, (i) a payment by check, draft or other
     instrument received at or before 12:00 p.m., St. Louis time, on a Business
     Day shall be deemed to have been applied to the relevant Loan Obligation on
     the second following Business Day, (ii) a payment by check, draft or other
     instrument received on a day that is not a Business Day or after 12:00 p.m.
     on a Business Day shall be deemed to have been applied by Lender to the
     relevant Loan Obligation on the third following Business Day, (iii) a
     payment in cash or by wire transfer received at or before 12:00 p.m., St.
     Louis time, on a Business Day shall be deemed to have been applied to the
     relevant Loan Obligation on the Business
<PAGE>
 
     Day when it is received, and (iv) a payment in cash or by wire transfer
     received on a day that is not a Business Day or after 12:00 p.m., St. Louis
     time, on a Business Day shall be deemed to have been applied to the
     relevant Loan Obligation on the next Business Day.

          5.5.4.  Returned Checks. If a payment is made by check, draft or other
     instrument and the check, draft or other instrument is returned to Lender
     unpaid, the application of the payment to the Loan Obligation will be
     reversed and will be treated as never having been made.

     5.6.  Due Dates Not on Business Days. If any payment required hereunder
becomes due on a date that is not a Business Day, then such due date shall be
deemed automatically extended to the next Business Day.

6.  Indemnity for Returned Payments. If after receipt of any payment of, or
proceeds applied to the payment of, all or any part of the Loan Obligations,
Lender is for any reason compelled to surrender such payment or proceeds to any
Person because such payment or application of proceeds is invalidated, declared
fraudulent, set aside, determined to be void or voidable as a preference, an
impermissible setoff, or a diversion of trust funds, or for any other reason,
then the Loan Obligations or part thereof intended to be satisfied shall be
revived and this Agreement shall continue in full force and Borrower shall be
liable to pay to Lender, and hereby does indemnify Lender and hold Lender
harmless for, the amount of such payment or proceeds surrendered. The provisions
of this Section shall be and remain effective notwithstanding any contrary
action which may be taken by Lender in reliance upon any such payment or
application of proceeds, and any such contrary action so taken shall be without
prejudice to Lender's rights under this Agreement and shall be deemed to have
been conditioned upon such payment or application of proceeds having become
final and irrevocable. The provisions of this Section shall survive termination
of the Revolving Commitment, the Convertible Revolving Commitment, the Term
Commitment and the payment and satisfaction of all of the Loan Obligations.

7.  Borrowing Procedure and Limits.

     7.1.  Revolving Advances. Borrower may request a Revolving Advance or
Convertible Revolving Advance by submitting a Revolving Advance Request to
Lender. Only a written request (which may be mailed, personally delivered or
telecopied as provided in Section ) from a Borrowing Officer to Lender that
specifies the amount of the Revolving Advance or Convertible Revolving Advance
to be made, the date the proceeds of the Revolving Advance or Convertible
Revolving Advance are requested to be made available to Borrower (the "Revolving
Advance Date"), whether it is to be a LIBOR Advance or an Adjusted CBR Advance,
and the Interest Period to be applicable to the Advance if it is a LIBOR Advance
shall be treated as a "Revolving Advance Request". Each Revolving Advance and
Convertible Revolving Advance shall be in an amount of no less than $50,000 that
is a whole multiple of $10,000. A Revolving Advance Request received by Lender
on a day that is not a Business Day or that is received by Lender after 2:00
p.m., St. Louis time, on a Business Day shall be treated as having been received
by Lender at 2:00 p.m., St. Louis time, on the next Business Day. A Revolving
Advance Request shall become irrevocable at 2:00 p.m., St. Louis time, on the
Revolving Advance Date unless it is sooner revoked by a Borrowing Officer.
Lender shall incur no liability to Borrower for treating any such request as a
Revolving Advance Request or for treating a revocation thereof as such if Lender
believes in good faith that the Person
<PAGE>
 
making the request or revocation is a Borrowing Officer.  Lender shall also
incur no liability to Borrower for failing to treat any such request as a
Revolving Advance Request or for treating a revocation thereof as such if Lender
believes in good faith that the Person making the request or revocation is not a
Borrowing Officer.  Each Revolving Advance Request by a Borrowing Officer shall
constitute a certification by Borrower that (i) no Default has occurred that is
continuing and not waived in writing by Lender and no Event of Default has
occurred that is not waived in writing by Lender, (ii) all representations and
warranties of Borrower in this Agreement are then true, and will be true on the
Revolving Advance Date, as if then made, and (iii) all conditions precedent
hereunder to the making of the requested Revolving Advance or Convertible
Revolving Advance have been satisfied.  There may not be more than one Revolving
Advance or Convertible Revolving Advance made pursuant to a Revolving Advance
Request on any one day.  Provided that all conditions precedent herein to a
requested Revolving Advance or Convertible Revolving Advance have been
satisfied, Lender will fund the amount of such requested Revolving Advance or
Convertible Revolving Advance, as applicable into the Concentration Account on
the Revolving Advance Date.

     7.2.  Lender's Right to Make Other Revolving Advances. Lender shall have
the right to make Revolving Advances or Convertible Revolving Advances at any
time and from time to time to cause timely payment of any of the Loan
Obligations. Lender will give notice to Borrower after making any such Revolving
Advance or Convertible Revolving Advance.

     7.3.  Term Conversions. Borrower may request a Term Conversion by
submitting a Term Conversion Request to Lender. Only a written request (which
may be mailed, personally delivered or telecopied as provided in Section ) from
a Borrowing Officer to Lender that specifies the amount of the Term Conversion
to be made, the Term Conversion Repayment Period, and the date the Term
Conversion is requested to be made (the "Term Conversion Date") shall be treated
as a "Term Conversion Request". If at any time the Convertible Revolving Loan
exceeds $7,500,000, Borrower shall be deemed to have made a Term Conversion
Request in the amount of $7,500,000. Each Term Conversion shall be made in an
amount of no less than $2,000,000 that is a whole multiple of $250,000. A Term
Conversion Request received by Lender on a day that is not a Business Day or
that is received by Lender after 2:00 p.m., St. Louis time, on a Business Day
shall be treated as having been received by Lender at 2:00 p.m., St. Louis time,
on the next Business Day. A Term Conversion Request shall become irrevocable at
2:00 p.m., St. Louis time, on the Term Conversion Date unless it is sooner
revoked by a Borrowing Officer. Lender shall incur no liability to Borrower for
treating any such request as a Term Conversion Request or for treating a
revocation thereof as such if Lender believes in good faith that the Person
making the request or revocation is a Borrowing Officer. Lender shall also incur
no liability to Borrower for failing to treat any such request as a Term
Conversion Request if Lender believes in good faith that the Person making the
request is not a Borrowing Officer. Each Term Conversion Request by a Borrowing
Officer shall constitute a certification by Borrower that (i) no Default has
occurred that is continuing and not waived in writing by Lender and no Event of
Default has occurred that is not waived in writing by Lender, (ii) all
representations and warranties of Borrower in this Agreement are then true, and
will be true on the Term Conversion Date, as if then made, and (iii) all
conditions precedent hereunder to the making of the requested Term Conversion
have been satisfied. There may not be more than one Term Conversion made
pursuant to a Term Conversion Request on any one day. Provided that all
conditions precedent herein to a requested Term Conversion have been satisfied,
Lender will make the requested Term Conversion on the later to occur of (i) the
date Lender receives a
<PAGE>
 
Term Note from Borrower to evidence the Conversion Term Loan created by such
Term Conversion or (ii) the Term Conversion Date.

     7.4.  Restriction on Number of LIBOR Loans. No more than ten LIBOR Loans
with different Interest Periods may be outstanding at any one time.

     7.5.  Suspension of Obligation to Make LIBOR Advances. If (i) on any date
for determining the LIBO Rate for any Interest Period, by reason of any changes
arising after the Execution Date affecting the London Interbank Market, or
Lender's position in such market, adequate and fair means do not exist for
ascertaining the applicable interest rate on the basis provided for in the
definition herein of LIBO Rate, or (ii) the making of any Advance which is to be
a LIBOR Advance or the continuance of any LIBOR Advance by Lender has become
unlawful by compliance by Lender in good faith with any Law or any pronouncement
of a Governmental Authority (whether or not having the force of law and whether
or not failure to comply therewith would be unlawful), then Lender shall
promptly give notice to Borrower of such determination. Until Lender notifies
Borrower that the circumstances giving rise to the suspension described herein
no longer exist, (a) the obligation of Lender to make Advances which are LIBOR
Advances shall be suspended, (b) each outstanding LIBOR Advance from Lender
shall be automatically converted into an Adjusted CBR Advance on the earlier of
the last day of the Interest Period for such LIBOR Advance or the last date
permitted by applicable law, and (c) all Revolving Advances from Lender shall be
Adjusted CBR Advances. Notwithstanding anything to the contrary contained
herein, if a LIBOR Advance is converted to an Adjusted CBR Advance pursuant to
this Section 7.5, the per annum interest rate applicable thereto from and after
the effective date of such conversion shall be the Adjusted CBR (but otherwise
calculated as provided in Section ).

8.  Security and Guaranties. As security for payment and performance of the Loan
Obligations, Borrower shall on the Execution Date execute and deliver, or cause
to be executed and delivered, to Lender the following documents:

     8.1.  Security.

          8.1.1.  security agreements from Borrower granting to Lender a
     security interest in all of the Goods, Equipment, Accounts, Inventory,

     whether now owned or hereafter acquired, and all proceeds thereof (the
     "Borrower Personal Property Collateral"), subject only to Permitted Liens
     affecting such property (each such security agreement that Borrower
     executes and delivers to Lender, either on or after the Execution Date, and
     as it may be amended, restated or replaced from time to time, a "Borrower
     Security Agreement");

          8.1.2.  stock pledge agreements granting to Lender a lien and security
     interest in all of the capital stock and other Securities of every
     Subsidiary and Affiliate of Borrower, now or hereafter issued and
     outstanding, and all proceeds thereof (each such stock pledge agreement
     that Borrower or any Subsidiary or Affiliate of Borrower executes and
     delivers to Lender, either on or after the Execution Date, and as it may be
     amended, restated, or replaced from time to time, a "Stock Pledge
     Agreement");
<PAGE>
 
          8.1.3.  subordination agreements as required by Lender, executed by
     Persons having any security interest in the assets of Borrower or any
     Covered Person, including, but not limited to, a subordination agreement
     executed by Resurgens Communications Group, Inc., with respect to its liens
     and security interests under that certain agreement For The Provision of
     Billing and Collection Services By Resurgens Communications Group, Inc. To
     Phone Zone dated June 2, 1992, and that certain Agreement for Operator
     Services dated June 2, 1992 between Resurgens and Phone Zone, as the same
     may be amended, renewed, restated or otherwise modified (the "Resurgens
     Agreements") (each such subordination agreement that Borrower causes to be
     executed and delivered to Lender, either on or after the Execution Date,
     and as it may be amended, restated or replaced from time to time, a
     "Subordination Agreement");

          8.1.4.  a collateral assignment of contracts (the "Assignment of
     Contracts") among Borrower, Phone Zone, Inc. and Lender, assigning to
     Lender (i) all of Borrower's rights and interest in the Equipment Lease
     Agreement and certain other contracts and (ii) all of Phone Zone, Inc.'s
     right, title and interest in the Resurgens Agreements.

     Lender may, in its sole discretion, (i) exchange, waive or release any of
     the Collateral, (ii) apply Collateral and direct the order or manner of
     sale thereof as Lender may determine, and (iii) settle, compromise, collect
     or otherwise liquidate any Collateral in any manner, all without affecting
     the Loan Obligations or Lender's right to take any other action with
     respect to any other Collateral.

     8.2.  Guaranties. The Loan Obligations shall be guarantied jointly and
severally by all current and hereafter existing or acquired Subsidiaries of
Borrower that have significant assets or operations in the reasonable
determination of Lender including, but not limited to, Telaleasing Enterprises,

California corporation and Jax Payphones, Inc., a Florida corporation, pursuant
to one or more continuing guaranties satisfactory to Lender (each and
collectively, as the same may be amended, restated or replaced from time to
time, the "Guaranty").

     8.3.  Guarantor Security Agreements. The obligations of Guarantors under
the Guaranty shall be secured by security agreements from each Guarantor
granting to Lender a security interest in all of the Goods, Equipment, Accounts,
Inventory, Instruments, Documents, Chattel Paper, General Intangibles and other
personal property of such Guarantor, whether now owned or hereafter acquired,
and all proceeds thereof (the "Guarantor Personal Property Collateral"), subject

     Except as otherwise described the disclosure schedule that is attached
hereto as Exhibit (the "Disclosure Schedule"), Borrower represents and warrants
to Lender as follows:

     11.1.  Organization and Existence. Each Covered Person is duly organized
and existing in good standing under the laws of the state of its organization,
is duly qualified to do business and is in good standing in every state where
the nature or extent of its business or properties require it to be qualified to
do business, except where the failure to so qualify will not have a Material
Adverse Effect. Each Covered Person has the power and authority to own its
properties and carry on its business as now being conducted.

     11.2.  Authorization. Each Covered Person is duly authorized to execute and
perform every Loan Document to which such Covered Person is a party, and
Borrower is duly authorized to borrow hereunder, and this Agreement and the
other Loan Documents have been duly authorized by all requisite corporate action
of each Covered Person. No consent, approval or authorization of, or declaration
or filing with, any Governmental Authority, and no consent of any other Person,
is required in connection with Borrower's execution, delivery or performance of
this Agreement and the other Loan Documents, except for those already duly
obtained.

party has been executed on behalf of such Covered Person by a Person duly
authorized to do so.

     11.4.  Enforceability of Obligations. Each of the Loan Documents to which a
Covered Person is a party constitutes the legal, valid and binding obligation of
such Covered Person, enforceable against such Covered Person in accordance with
its terms, except to the extent that the enforceability thereof against such
Covered Person may be limited by bankruptcy, insolvency, reorganization,
moratorium or similar laws affecting creditors' rights generally or by equitable
principles of general application.
<PAGE>
 
     11.5.  Burdensome Obligations. No Covered Person is a party to or bound by
any Contract or is subject to any provision in the Charter Documents of such
Covered Person which would, if performed by such Covered Person, result in a
Default or Event of Default either immediately or upon the elapsing of time.

     11.6.  Legal Restraints. The execution of any Loan Document by a Covered
Person will not violate or constitute a default under the Charter Documents of
such Covered Person, any Material Agreement of such Covered Person, or any
Material Law, and will not, except as expressly contemplated or permitted in
this Agreement, result in any Lien being imposed on any of such Covered Person's
property. The performance by any Covered Person of its obligations under any
Loan Document to which it is a party will not violate or constitute a default
under the Charter Documents of such Covered Person, any Material Agreement of
such Covered Person, or any Material Law, and will not, except as expressly
contemplated or permitted in this Agreement, result in any Lien being imposed on
any of such Covered Person's property.

     11.7.  Labor Disputes. There is no collective bargaining agreement or other
labor contract covering employees of a Covered Person, and no such collective
bargaining agreement or other labor contract is scheduled to expire during the
term of this Agreement. No union or other labor organization is seeking to
organize, or to be recognized as, a collective bargaining unit of employees of a
Covered Person for any similar purpose, and there is no pending or, to the best
of Borrower's knowledge, threatened, strike, work stoppage, material unfair

     Employment Laws which, if adversely determined, would have a Material
     Adverse Effect on Borrower.

          11.10.3.  Investigations. None of the operations of any Covered Person
     are the subject of investigation by any Governmental Authority regarding
     the improper transportation, storage, disposal, generation or release into
     the environment of any Hazardous Waste, the results of which may have a
     Material

     Adverse Effect on such Covered Person, on the value of the Collateral, or
     on the overall assets of such Covered Person.

          11.10.4.  Notices; Reports. No notice or report under any
     Environmental Law indicating a past or present spill or release into the

     11.21.  Tax Liabilities; Governmental Charges. Each Covered Person has
filed or caused to be filed all tax reports and returns required to be filed by
it with any Governmental Authority, except where extensions have been properly
obtained or where such Covered Person was unaware of any obligation to file a
report or return, and has paid or made adequate provision for payment of all
taxes, assessments, fees and other charges levied upon it or upon its income or
properties by any Governmental Authority which are due and payable, including
interest and penalties, except such taxes, assessments, fees and other charges,
if any, as are being diligently contested in good faith by appropriate
proceedings and as to which such Covered Person has established adequate
reserves in conformity with GAAP on the books of such Covered Person. No Liens
for any such taxes, assessments, fees or other charges have been filed and no
claims are being asserted with respect to any such taxes, assessments, fees or
other charges which, if adversely determined, would have a Material Adverse
Effect on such Covered Person. Except as disclosed on Exhibit , none of the
federal income tax returns of any Covered Person has ever been audited by the
Internal Revenue Service. There are no material unresolved issues concerning any
tax liability of a Covered Person which, if adversely determined, would have a
Material Adverse Effect on such Covered Person.

     committed a breach of any of the responsibilities or obligations imposed
     upon fiduciaries by Title I of ERISA.

          11.22.2.  Claims. There are no claims, pending or threatened,
     involving any such Pension Benefit Plan by a current or former employee (or
     beneficiary thereof) of such Covered Person or ERISA Affiliate, nor is
     there any reasonable basis to anticipate any claims involving any such
     Pension Benefit Plan which would likely be successfully maintained against
     such Covered Person or ERISA Affiliate.

          11.22.3.  Reporting and Disclosure Requirements. There are no
     violations of any reporting or disclosure requirements with respect to any
     such Pension Benefit Plan and none of such Pension Benefit Plans has
     violated any applicable Law, including but not limited to ERISA and the
     Code.
<PAGE>

     reasonably expected to be in reorganization or to be terminated within the
     meaning of Title IV of ERISA.

     11.23.  Welfare Benefit Plans. No Covered Person or ERISA Affiliate
maintains a Welfare Benefit Plan that has a liability which, if enforced or

COBRA.

     11.24.  Retiree Benefits. No Covered Person or ERISA Affiliate has an

maintain its existence in good standing and its right to transact business in
those states in which it is now or hereafter doing business, except where the
failure to do so would not have a Material Adverse Effect on Borrower. Each

Person. Notwithstanding anything in this Section to the contrary, any Covered
Person may transfer its assets, including without limitation Material Licenses,
to another Covered Person, provided that Borrower gives Lender prior written

otherwise discontinue its right to transact business.

Covered Person shall maintain in good standing and free of defaults all of its
leases of buildings, equipment, machinery, fixtures and other real and personal
property whose useful economic life has not elapsed and which is necessary for

in such manner and to such extent and covering such risks as such properties are
usually insured. Each Covered Person shall at all times carry insurance, with
insurance companies having a rating of at least "A" by Best's Rating Service,
against liability on account of damage to persons or property (including product

consent, to adjust and compromise proceeds payable under such policies of
insurance, (ii) to collect, receive and give receipts for such proceeds in the
name of Borrower and Lender, and (iii) to endorse Borrower's name upon any
instrument in payment thereof. Such power granted to Lender shall be deemed
coupled with an interest and shall be irrevocable. All policies of insurance
maintained hereunder shall contain a clause providing that such policies may not
be canceled, reduced in coverage or otherwise modified without 30 days prior
written notice to Lender. Borrower shall upon request of Lender at any time
furnish updated Evidence of Insurance (in the form required as a condition to
Lender's lending hereunder) for such insurance to Lender.

therefrom and all claims of materialmen, mechanics, carriers, warehousemen,
landlords and other like Persons for labor, materials, supplies, storage or
other items or services which if unpaid might be or become a Lien or charge upon
any of its property; provided, however, that nothing herein contained shall be
construed as prohibiting a Covered Person from diligently contesting in good
faith by appropriate proceedings the validity of any such taxes, rates, levies,
or assessments, provided such Covered Person has established adequate reserves
therefor in conformity with GAAP on the books of such Covered Person, and no
Lien, other than a Permitted Lien, results from such non-payment.

under Section 401(a)(29) of the Code; (3) shall at all times make prompt
payments or contributions to meet the minimum funding standards set forth in

           announcement at any adjourned sale without being required to
           give a new notice of sale, all as Lender deems advisable, for
           cash or credit; provided, however, that Lender may become the
           purchaser at any such sale if permissible under applicable Law
           and Lender may, in lieu of actual payment of the purchase price,
           offset the amount thereof against Borrower's obligations owing
           to Lender; and Borrower agrees that Lender has no obligation to
           preserve rights to Collateral against prior parties or to
           marshal any Collateral for the benefit of any Person;

      In connection with the advertising for sale, selling or otherwise
      realizing upon any of the Collateral securing the obligations of
      Borrower to Lender, Lender may use and is hereby granted a license to
      use, without charge or liability to Lender therefor, any of Borrower's
      labels, trade names, trademarks, trade secrets, service marks, patents,
      patent applications, licenses, certificates of authority, advertising
      materials, or any of Borrower's other properties or interests in
      properties of similar nature, to the extent that such use thereof is not
      prohibited by agreements under which Borrower has rights therein, and
      all of Borrower's rights under license, franchise and similar agreements
      shall inure to Lender's benefit.

           16.4.7.  Miscellaneous.  Upon the occurrence of an Event of Default
      and at any time thereafter, Lender may exercise any other rights and
<PAGE>
 
      remedies available to Lender under the Loan Documents or otherwise
      available to Lender at law or in equity.

           16.4.8.  Application of Funds.  Any funds received by Lender with
      respect to the Loan Obligations after any acceleration, including but
      not limited to proceeds of Collateral, shall be applied as follows:  (i)
      first, to reimburse Lender for any amounts due to Lender under Sections
      and ; (ii) second, to the payment of all other amounts due hereunder
      (other than the Loans and interest accrued thereon); (iii) third, to the
      payment of interest accrued on the Loans; (iv) fourth, to the payment of
      the Loans, in such order as Lender determines in its sole discretion;
      and (v) fifth, to the payment of the other Loan Obligations.  Any
      remaining amounts shall be paid to Borrower or such other Persons as
      shall be legally entitled thereto.

      16.5.  Limitation of Liability; Waiver. Lender shall not be liable to
Borrower as a result of any commercially reasonable possession, repossession,
collection or sale by Lender of Collateral; and Borrower hereby waives all
rights of redemption from any such sale and the benefit of all valuation,
appraisal and exemption laws. If Lender seeks to take possession of any of the
Collateral by replevin or other court process, Borrower hereby irrevocably
waives (i) the posting of any bonds, surety and security relating thereto
required by any statute, court rule or otherwise as an incident to such
possession, (ii) any demand for possession of the Collateral prior to the
commencement of any suit or action to recover possession thereof, (iii) any
requirement that Lender retain possession and not dispose of any Collateral
until after trial or final judgment, and (iv) to the extent permitted by
applicable law, all rights to notice and hearing prior to the exercise by Lender
of Lender's right to repossess the Collateral without judicial process or to
replevy, attach or levy upon the Collateral without notice or hearing. Lender
shall have no obligation to preserve rights to the Collateral or to marshall any
Collateral for the benefit of any Person.

      16.6  Notice.  Any notice of intended action required to be
given by Lender, if given as provided in Section  at least 10 calendar days
prior to such proposed action, shall be effective and constitute commercially
reasonable and fair notice to Borrower.

      17.    Miscellaneous.

      17.1.  Notices.  All notices, consents, requests and demands to or upon
the respective parties hereto shall be in writing, and shall be deemed to have
been given or made when delivered in person to those Persons listed on the
signature pages hereof or when deposited in the United States mail, postage
prepaid, or, in the case of telegraphic notice, or the overnight courier
services, when delivered to the telegraph company or overnight courier service,
or in the case of telex or telecopy notice, when sent, verification received, in
each case addressed as set forth on the signature pages hereof, or such other
address as either party may designate by notice to the other in accordance with
the terms of this paragraph. No notice given to or demand made on Borrower by
Lender in any instance shall entitle Borrower to notice or demand in any other
instance.

      17.2.  Right to Cure.  Lender may from time to time, in its sole
discretion (but shall have no obligation to do so), for Borrower's account and
at Borrower's expense, pay (or make a Revolving Advance or Convertible Revolving
Advance to pay) any amount or do any act required of Borrower hereunder or
requested by Lender to preserve, protect, maintain
<PAGE>
 
or enforce the Loan Obligations, the Collateral or Lender's Liens thereon, and
which Borrower fails to pay or do, including, without limitation, payment of any
judgment against Borrower, insurance premium, taxes or assessments, warehouse
charge, finishing or processing charge, landlord's claim, and any other Lien
upon or with respect to the Collateral. All payments that Lender makes pursuant
to this Section and all out-of-pocket costs and expenses that Lender pays or
incurs in connection with any action taken by it hereunder shall be a part of
the Loan Obligations, the repayment of which shall be secured by the Collateral.
Any payment made or other action taken by Lender pursuant to this Section shall
be without prejudice to any right to assert an Event of Default hereunder and to
pursue Lender's other rights and remedies with respect thereto.

      17.3.  Amendments, Waivers and Consents.  No amendment to, waiver of, or
departure from full compliance with any provision of this Agreement, or of any
of the other Loan Documents, or consent to any departure by Borrower herefrom or
therefrom, shall be effective unless it is in writing and signed by authorized
officers of Borrower and the Lender; provided, however, that any such waiver or
consent shall be effective only in the specific instance and for the purpose for
which given. No failure by Lender to exercise, and no delay by Lender in
exercising, any right, remedy, power or privilege hereunder shall operate as a
waiver thereof, nor shall any single or partial exercise by Lender of any right,
remedy, power or privilege hereunder preclude any other exercise thereof, or the
exercise of any other right, remedy, power or privilege.

      17.4.  Rights Not Exclusive.  Every right granted to Lender hereunder or
under any other Loan Document or allowed to it at law or in equity shall be
deemed cumulative and may be exercised from time to time.

      17.5.  Survival of Agreements.  All covenants and agreements made herein
and in the other Loan Documents shall survive the execution and delivery of this
Agreement, the Notes and other Loan Documents and the making of every Advance
and every Term Conversion. All agreements, obligations and liabilities of
Borrower under this Agreement concerning the payment of money to Lender,
including but not limited to Borrower's obligations under Sections and , but
excluding the obligation to repay the Loans and interest accrued thereon, shall
survive the repayment in full of the Loans and interest accrued thereon, the
return of the Notes to Borrower and the termination of the Commitments.

      17.6.  Successors and Assigns.  This Agreement shall be binding upon and
inure to the benefit of the parties hereto and all future holders of the Notes
and their respective successors and assigns, except that Borrower may not
assign, delegate or transfer any of its rights or obligations under this
Agreement without the prior written consent of Lender. With respect to
Borrower's successors and assigns, such successors and assigns shall include,
without limitation, any receiver, trustee or debtor-in-possession of or for
Borrower. Lender shall have the right to assign its rights and to delegate its
obligations under the Loan Documents to one or more financial institutions
selected by Lender and reasonably acceptable to Borrower that assumes Lender's
obligations to make Revolving Advances, Convertible Revolving Advances, and
Conversion Term Loans to Borrower subject to the terms and conditions herein.
Lender shall have the right to assign its rights under the Loan Documents to any
Federal Reserve Bank, but without delegation of Lender's obligations thereunder.

      17.7.  Participations.  Lender may in the ordinary course of its
commercial banking business and in accordance with applicable law grant
participations to one or more
<PAGE>
 
banks or other financial institutions in the Loans. For this purpose, Lender may
disclose to a potential or actual participant any information supplied to Lender
by or on behalf of Borrower. Borrower hereby acknowledges and agrees that every
such participant has the same right of set-off as does Lender under Section ;
provided, however, that all amounts received by any such participant through the
exercise of the right of set-off in excess of its share of the Loans as a
participant shall be remitted to Lender.

      17.8.  Payment of Expenses.  Borrower agrees to pay or reimburse Lender
for its costs and expenses incurred in connection with Lender's due diligence
review, the negotiation and preparation of the Loan Documents, and the
perfection of Lender's liens and security interests in the Collateral, including
but not limited to recording and filing fees, appraisal fees, environmental
consultant fees, all actual attorney's expenses advanced (including but not
limited to expenses for lien searches and filing charges, facsimile and other
electronic data transmissions, long-distance telephone charges, courier and
delivery charges and photocopying charges) and reasonable attorneys' fees.
Further, if at any time or times hereafter Lender engages legal counsel for
advice or other representation to enforce the rights of Lender against Borrower
under the Loan Documents or in connection with any amendment, supplement,
waiver, consent or subsequent closing relating to any of the Loan Documents at
the request of Borrower or as a consequence of a Default or Event or Default,
then all reasonable fees and all expenses advanced of such legal counsel and all
litigation costs, including costs incurred as a consequence of any proceedings
involving Borrower under the federal Bankruptcy Code (if any) shall constitute a
part of the Loan Obligations and be payable on demand.

      17.9.  Indemnity.  Borrower shall pay, indemnify and hold harmless Lender
and its directors, officers, employees, agents, and representatives (the
"Indemnified Parties") for, from and against, and promptly reimburse the
Indemnified Parties for, any and all claims, damages, liabilities, losses, costs
and expenses (including, without limitation, reasonable attorneys' fees and
expenses and amounts paid in settlement) (the "Indemnified Liabilities")
incurred, paid or sustained by the Indemnified Parties in connection with,
arising out of, based upon or otherwise involving or resulting from any
threatened, pending or completed action, suit, investigation or other proceeding
by, against or otherwise involving the Indemnified Parties and in any way
dealing with, relating to or otherwise involving this Agreement, any of the
other Loan Documents, or any transaction contemplated hereby or thereby (each a
"Triggering Event"); provided, however, that Borrower shall have no obligation
to indemnify the Indemnified parties hereunder with respect to any Indemnified
Liabilities arising from the gross negligence, bad faith or willful misconduct
of any of the Indemnified Parties. The obligations of Borrower under this
Section shall survive the termination of the Commitments, the payment and
satisfaction of all of the Loan Obligations, and the release of the Collateral.
To the extent that any of the indemnities set forth in this Section may be
unenforceable because it is violative of any Law or public policy, Borrower
shall pay the maximum portion which it is permitted to pay under applicable law.

      17.10.  Changes in Accounting Principles.  If Borrower, at the end of its
Fiscal Year and with the concurrence of its independent certified public
accountants, changes the method of valuing the Inventory of Borrower, or if any
other changes in accounting principles from those used in the preparation of any
of the Financial Statements are required by or result from the promulgation of
principles, rules, regulations, guidelines, pronouncements or opinions by the
Financial Accounting Standards Board or the American Institute of Certified
Public Accountants (or successors thereto or bodies with similar
<PAGE>
 
functions), and any of such changes result in a change in the method of
calculation of, or affect the results of such calculation of, any of the
financial covenants, standards or terms found herein, then the parties hereto
agree to enter into and diligently pursue negotiations in order to amend such
financial covenants, standards or terms so as to equitably reflect such changes,
with the desired result that the criteria for evaluating the financial condition
and results of operations of Borrower shall be the same after such changes as if
such changes had not been made; provided, however, that until such changes are
made, all financial covenants herein and all the provisions hereof which
contemplate financial calculation hereunder shall remain in full force and
effect.

      17.11.  Loan Records.  The date and amount of all Advances to Borrower,
Term Conversions and payments of amounts due from Borrower under the Loan
Documents will be recorded in the records that Lender normally maintains for
such types of transactions. The failure to record, or any error in recording,
any of the foregoing shall not, however, affect the obligation of Borrower to
repay the Loans and other amounts payable under the Loan Documents. Borrower
shall have the burden of proving that Lender's records are not correct. Borrower
agrees that Lender's books and records showing the Loan Obligations and the
transactions pursuant to this Agreement shall be admissible in any action or
proceeding arising therefrom, and shall constitute prima facie proof thereof,
irrespective of whether any Loan Obligation is also evidenced by a promissory
note or other instrument. Lender will provide to Borrower a monthly statement of
Advances, Term Conversions, payments, and other transactions pursuant to this
Agreement. Such statement shall be deemed correct, accurate and binding on
Borrower and an account stated (except for reversals and reapplications of
payments as provided in Section and corrections of errors discovered by Lender),
unless Borrower notifies Lender in writing to the contrary within thirty (30)
days after such statement is rendered. In the event a timely written notice of
objections is given by Borrower, only the items to which exception is expressly
made will be considered to be disputed by Borrower.

      17.12.  Other Security and Guaranties.  Lender may, without notice or
demand and without affecting Borrower's obligations hereunder, from time to
time: (a) take from any Person and hold collateral (other than the Collateral)
for the payment of all or any part of the Loan Obligations and exchange, enforce
and release such collateral or any part thereof; and (b) accept and hold any
endorsement or guaranty of payment of all or any part of the Loan Obligations
and release or substitute any such endorser or guarantor, or any Person who has
given any Lien in any other collateral as security for the payment of all or any
part of the Loan Obligations, or any other Person in any way obligated to pay
all or any part of the Loan Obligations.

      17.13.  Severability.  Any provision of this Agreement which is
prohibited, unenforceable or not authorized in any jurisdiction shall, as to
such jurisdiction, be ineffective to the extent of such prohibition,
unenforceability or lack of authorization without invalidating the remaining
provisions hereof or affecting the validity, enforceability or legality of such
provision in any other jurisdiction unless the ineffectiveness of such provision
would result in such a material change as to cause completion of the
transactions contemplated hereby to be unreasonable.

      17.14.  Counterparts.  This Agreement may be executed by the parties
hereto on any number of counterparts and on separate counterparts, and all such
counterparts taken together shall constitute one and the same instrument. It
shall not be necessary in
<PAGE>
 
making proof of this Agreement to produce or account for more than one
counterpart signed by the party to be charged.

      17.15.  Governing Law; No Third Party Rights.  THIS AGREEMENT, THE OTHER
LOAN DOCUMENTS AND THE NOTES AND THE RIGHTS AND OBLIGATIONS OF THE PARTIES
HEREUNDER AND THEREUNDER SHALL BE GOVERNED BY AND CONSTRUED AND INTERPRETED IN
ACCORDANCE WITH THE INTERNAL LAWS OF THE STATE OF MISSOURI APPLICABLE TO
CONTRACTS MADE AND TO BE PERFORMED WHOLLY WITHIN SUCH STATE. This Agreement is
solely for the benefit of the parties hereto and their respective successors and
assigns, and no other Person shall have any right, benefit, priority or interest
under, or because of the existence of, this Agreement.

      17.16.  Choice of Forum.  SUBJECT ONLY TO THE EXCEPTION IN THE NEXT
SENTENCE, BORROWER AND LENDER HEREBY AGREE TO THE EXCLUSIVE JURISDICTION OF THE
FEDERAL COURT OF THE EASTERN DISTRICT OF MISSOURI AND THE STATE COURTS OF
MISSOURI LOCATED IN ST. LOUIS COUNTY AND THE CITY OF ST. LOUIS, MISSOURI, AND
WAIVE ANY OBJECTION BASED ON VENUE OR FORUM NON CONVENIENS WITH RESPECT TO ANY
ACTION INSTITUTED THEREIN, AND AGREE THAT ANY DISPUTE CONCERNING THE
RELATIONSHIP BETWEEN LENDER AND BORROWER OR THE CONDUCT OF EITHER PARTY IN
CONNECTION WITH THIS AGREEMENT OR OTHERWISE SHALL BE HEARD ONLY IN THE COURTS
DESCRIBED ABOVE. NOTWITHSTANDING THE FOREGOING: (1) LENDER SHALL HAVE THE RIGHT
TO BRING ANY ACTION OR PROCEEDING AGAINST BORROWER OR ITS PROPERTY IN ANY COURTS
OF ANY OTHER JURISDICTION LENDER DEEMS NECESSARY OR APPROPRIATE IN ORDER TO
REALIZE ON THE COLLATERAL, REAL ESTATE OR OTHER SECURITY FOR THE LOAN
OBLIGATIONS, AND (2) EACH OF THE PARTIES HERETO ACKNOWLEDGES THAT ANY APPEALS
FROM THE COURTS DESCRIBED IN THE IMMEDIATELY PRECEDING SENTENCE MAY HAVE TO BE
HEARD BY A COURT LOCATED OUTSIDE THOSE JURISDICTIONS.

      17.17.  Jury Trial.  BORROWER AND LENDER EACH HEREBY WAIVES ANY RIGHT TO
TRIAL BY JURY OF ANY CLAIM, DEMAND, ACTION OR CAUSE OF ACTION (1) ARISING UNDER
THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT, OR (2) IN ANY WAY CONNECTED WITH OR
RELATED OR INCIDENTAL TO THE DEALINGS OF THE PARTIES HERETO OR EITHER OF THEM IN
RESPECT OF THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT, OR THE TRANSACTIONS
RELATED HERETO OR THERETO, IN EACH CASE WHETHER NOW EXISTING OR HEREAFTER
ARISING, AND WHETHER SOUNDING IN CONTRACT OR TORT OR OTHERWISE. EACH OF BORROWER
AND LENDER AGREES AND CONSENTS THAT ANY SUCH CLAIM, DEMAND, ACTION OR CAUSE OF
ACTION SHALL BE DECIDED BY COURT TRIAL WITHOUT A JURY AND THAT EITHER MAY FILE
AN ORIGINAL COUNTERPART OR A COPY OF THIS AGREEMENT WITH ANY COURT AS WRITTEN
EVIDENCE OF THE CONSENT OF THE PARTIES HERETO TO THE WAIVER OF THEIR RIGHT TO
TRIAL BY JURY.

Documents are incorporated in and made a part of this Agreement by this
reference.

Section 432.045 of the Missouri Revised Statutes; nothing contained in such
notice shall be deemed to limit or modify the terms of the Loan Documents:

      ORAL AGREEMENTS OR COMMITMENTS TO LOAN MONEY, EXTEND CREDIT OR TO
      FORBEAR FROM ENFORCING REPAYMENT OF A DEBT INCLUDING PROMISES TO EXTEND
      OR RENEW SUCH DEBT ARE NOT ENFORCEABLE.  TO PROTECT YOU (BORROWER) AND
      US (CREDITOR) FROM MISUNDERSTANDING OR DISAPPOINTMENT, ANY AGREEMENTS WE

                               FORM OF TERM NOTE

$________________    St. Louis, Missouri
                                                               __________, 199__

     For value received, Davel Communications Group, Inc., an Illinois
corporation ("Borrower") promises to pay to the order of THE BOATMEN'S NATIONAL
BANK OF ST. LOUIS, a national banking association ("Lender") the principal sum
of ________________________ DOLLARS ($___________________) in ______________
(____) consecutive equal principal payments to be made quarterly commencing on
_________________ ___, 199__, and on the first day of each calendar quarter
thereafter, through and including _________________ ___, 199__, with a final
installment in the amount of the remaining outstanding principal balance and all
accrued interest thereon being due on ______________ ___, 199__.

     Borrower further promises to pay interest from the date hereof on the
balance of said principal from time to time outstanding at a per annum rate or
rates determined pursuant to the Loan Agreement. Upon the occurrence of any
Event of Default as defined in the Loan Agreement, or at the option of Lender
upon the occurrence of a Default as defined in the Loan Agreement, all
outstanding principal and, to the extent permitted by law, accrued interest in
respect of this Term Note (this "Note"), and all other amounts owing hereunder
shall bear interest, payable on demand, at the Default Rate set forth in the
Loan Agreement. In addition, such default rate of interest shall apply after
Maturity, whether by acceleration or otherwise. All such interest shall be
computed on the basis of a year deemed to consist of 360 days and paid for the
actual number of days elapsed. Interest shall be payable on such dates as are
provided under the Loan Agreement.

     Both principal and interest are payable in Dollars to Lender at its office
at One Boatmen's Plaza, 800 Market Street, St. Louis, Missouri 63101
(Attention:_________________).

     This Note is referred to in, and is issued under the terms of, and pursuant
to the provisions of, that certain Amended and Restated Loan Agreement dated as
of August ___, 1996 between Lender and Borrower (as it may be further amended,
restated, extended, renewed, replaced, or otherwise modified from time to time,
the "Loan Agreement"). All capitalized terms used and not otherwise defined
herein shall have the same meanings as given them in the Loan Agreement.

     This Note is secured by the Collateral described in the Loan Documents,
executed from time to time by Borrower in favor of Lender as set forth in the
Loan Agreement and reference to the Loan Documents and the Loan Agreement is
made for a statement of the rights of the Lender with respect to such
Collateral.

     Borrower shall prepay the principal amount of this Note to the extent
provided in the Loan Agreement. Borrower may prepay the principal amount of this
Note to the extent and upon the conditions provided in the Loan Agreement.
<PAGE>
 
     The date and amount of all disbursements and receipts representing
principal and receipts of interest by Lender with respect to the Term Loan shall
be recorded by Lender in the records it maintains with respect thereto. The
failure to record, or any error in recording, any of the foregoing shall not,
however, affect the obligations of Borrower under this Note to repay the
principal amount advanced hereunder together with all interest accruing thereon.
Such record as maintained by Lender shall constitute prima facie evidence of the
amount outstanding under this Note.

     Reference is made to the Loan Agreement for provisions regarding the
acceleration of the maturity hereof on the occurrence of any Event of Default,
which provisions are incorporated herein by this reference.

     If any payment required under this Note or the Loan Agreement is not made
when due, or upon any other Event of Default, Borrower shall pay all costs of
collection on this Note, including but not limited to court costs and reasonable
attorneys fees and actual expenses of such attorneys, whether or not litigation
is commenced, including representation of Lender in connection with any
bankruptcy or insolvency proceeding of Borrower.

     Demand for payment, protest, notice of dishonor, and all other notices and
demands under this Note and any and all lack of diligence in the enforcement of
this Note are hereby waived by all who are or shall become parties to this Note
and the same hereby assent to each and every extension or postponement of the

         attached Financial Statements.

     3.  The examinations described in paragraph 2 did not disclose, and I have
         no knowledge of, the existence of any condition or event which
