<PAGE>   6

                                   SECTION 1.
                           AMOUNTS AND TERMS OF LOANS

                  1.1      Loans. Subject to the terms and conditions of this
Agreement, including, particularly, satisfaction of all those conditions
precedent set forth in Sections 7.1 and 7.2, and in reliance upon the
representations and warranties of each Loan Party contained herein and in each
Loan Document:

                  (A)      Revolving Loans. Each Lender agrees, severally and
not jointly, to lend to Borrower during the period from the Closing Date to (but
excluding) the Expiry Date its Pro Rata Share of any Loans requested by Borrower
to be made by Lenders under this Section 1.1(B) during such period, up to an
aggregate maximum amount for each Lender of its "Revolving Loan Commitment" as
specified opposite its name on its signature page, and up to an aggregate
maximum amount for all Lenders of Thirty-five Million Dollars ($35,000,000) (as
each of the same may be reduced or added to pursuant hereto or to a Lender
Addition Agreement, herein called, individually, as to each Lender, its
"Revolving Loan Commitment," and, collectively, as to all Lenders, their
"Revolving Loan Commitments") and, subject to the terms and conditions of
Section 1.1(C), to permit Borrower to obtain Letters of Credit from time to
time; provided, however, that the maximum amount of Loans which may be
outstanding hereunder at any one time, when aggregated with all then outstanding
L/C Exposure, shall not exceed the lesser of: (i) the aggregate Revolving Loan
Commitments or (ii) the Maximum Lending Multiple, as defined below in this
Section 1.1(B) (the lesser amount so determined hereinafter sometimes referred
to as the "Maximum Revolving Loan Balance"). Loans outstanding from time to time
made pursuant to the Revolving Loan Commitments are sometimes called herein
"Revolving Loans". Revolving Loans may be borrowed, repaid and reborrowed, but,
subject to earlier payment in accordance with the provisions of the last
paragraph of this Section 1.1(B) and Section 6.3, shall be repaid in full on the
Expiry Date, on which date the Revolving Loan Commitments shall cease to be
effective and no Revolving Loans may be obtained. The proceeds of the Revolving
Loans shall be used to supplement Borrower's or its Subsidiaries' working
capital, to finance their making of Capital Expenditures and for other general
corporate purposes of Borrower and its Subsidiaries consistent with the terms
and conditions of this Agreement; provided, however, that, unless otherwise may
be approved in writing by Agent and all Lenders, in their sole discretion, from
time to time, no proceeds of any Revolving Loan shall be used to finance, in
whole or in part, an Approved Acquisition. Written or telephonic notice must be
provided to Agent by Borrower by 11:00 a.m. (Atlanta time), on the Business Day
that such Revolving Loan is requested to be made, in the case of any Revolving
Loan requested to be made as a Base Rate Loan, and by 11:00 a.m. (Atlanta time)
on the third Business Day prior to the Business Day, in the case of any
Revolving Loan requested to be made as a LIBOR Loan. All Revolving Loans
requested telephonically by Borrower must be confirmed in writing by Borrower to
Agent within one (1) Business Day. Each such written notice (or written
confirmation of telephonic notice) shall be made in substantially the form of
the "Notice of Borrowing" annexed hereto as EXHIBIT A. As used in this Section
1.1(B), the "Maximum Lending Multiple" shall mean the product of (i) EBITDA,
determined for the Test Period ending as of the last day of Borrower's most
recently completed fiscal month for which financial statements have been
delivered to Agent in accordance with Section 4.1(A); multiplied by (ii) two and
five-tenths (2.5), which shall be


                                      -2-
<PAGE>   7

determined by Agent on the Closing Date and monthly thereafter, effective as of
the first day of each calendar month.

                  Borrower acknowledges that Lenders do not presently intend to
make, or permit to remain outstanding, Revolving Loans in an aggregate amount in
excess of the Maximum Revolving Loan Balance (such Revolving Loans in excess of
the Maximum Revolving Loan Balance being referred to as "Excess Revolving
Loans"); and if any such Excess Revolving Loans continue to exist for three (3)
Business Days or more after demand for repayment, the same shall constitute an
Event of Default. Notwithstanding the foregoing, however, if at any time
subsequent to the Closing Date, Borrower requests that Lenders make, or permit
to remain outstanding Excess Revolving Loans, the Requisite Lenders may, in
their sole discretion, elect to cause all Lenders to make, or permit to remain
outstanding, such Excess Revolving Loans, provided, however, that the Requisite
Lenders shall not cause all Lenders to make, or permit to remain outstanding,
either (i) Revolving Loans (including Excess Revolving Loans) which are in the
aggregate in excess of the Revolving Loan Commitments or (ii) Excess Revolving
Loans in excess of ten percent (10%) of the Maximum Revolving Loan Balance at
such time (without giving effect to the making of any such Excess Revolving
Loan), or (iii) Excess Revolving Loans which remain outstanding for more than
twenty one (21) consecutive days in any event. If Excess Revolving Loans are
made, or permitted to remain outstanding, pursuant to the preceding sentence,
then (a) the Maximum Revolving Loan Balance shall be deemed increased by the
amount of such Excess Revolving Loans, but only for so long as the Requisite
Lenders allow such Excess Revolving Loans to be outstanding and (b) all Lenders
that have committed to make Revolving Loans shall be bound to make, or permit to
remain outstanding, such Excess Revolving Loans based upon their Pro Rata Shares
thereof in accordance with the terms of this Agreement.

                  (B)      Letters of Credit.

                  (1)      Subject to the terms and conditions set forth herein,
in addition to Revolving Loans, Borrower may request the issuance of Letters of
Credit for its own account by the Issuing Lender, in a form reasonably
acceptable to the Issuing Lender, at any time and from time to time during the
term of the Revolving Loan Commitments. Letters of Credit issued hereunder shall
constitute utilization of the Revolving Loan Commitments. In the event of any
inconsistency between the terms and conditions hereof and the terms and
conditions of any form of letter of credit application or other agreement
submitted by the Borrower to, or entered into by the Borrower with, the Issuing
Lender relating to any Letter of Credit, the terms and conditions hereof shall
govern and control.

                  (2)      To request the issuance of a Letter of Credit (or the
amendment, renewal or extension of an outstanding Letter of Credit), Borrower
shall deliver to the Issuing Lender and the Agent (if not the Issuing Lender),
at least three (3) Business Days in advance of the requested date of issuance,
amendment, renewal or extension, a notice requesting the issuance of a Letter of
Credit, or identifying the Letter of Credit to be amended, renewed or extended,
the date of issuance, amendment, renewal or extension, the date on which such
Letter of Credit is to expire (which shall comply with paragraph (3) of this
Section), the amount of such Letter of Credit, whether the Letter of Credit is a
"standby" or "commercial" Letter of Credit, the name and


                                      -3-
<PAGE>   8

address of the beneficiary thereof and such other information as shall be
necessary to prepare, amend, renew or extend such Letter of Credit. If requested
by the Issuing Lender, Borrower also shall submit a letter of credit application
on the Issuing Lender's standard form in connection with any request for a
Letter of Credit. A Letter of Credit shall be issued, amended, renewed or
extended only if (and upon issuance, amendment, renewal or extension of each
Letter of Credit Borrower shall be deemed to represent and warrant that), after
giving effect to such issuance, amendment, renewal or extension (i) the
aggregate LC Exposure of the Issuing Lender (determined for these purposes
without giving effect to the participations therein of the Lenders pursuant to
paragraph (4) of this Section) shall not exceed the LC Commitment.

                  (3)      Each Letter of Credit shall expire at or prior to the
close of business on the earlier of (i) the date one (1) year after the date of
the issuance of such Letter of Credit (or, in the case of any renewal or
extension thereof, one (1) year after such renewal or extension) provided that
any such Letter of Credit may provide for automatic extensions thereof to a date
not later than one (1) year beyond its current expiration date, and (ii) the
date that is five (5) Business Days prior to the Expiry Date. No Letter of
Credit may be extended beyond the date that is five (5) Business Days prior to
the Expiry Date, however.

                  (4)      Upon its issuance of a Letter of Credit (or an
amendment to a Letter of Credit increasing the amount thereof) in accordance
with terms hereof, without any further action on its part, the Issuing Lender
shall be deemed to have granted to each Lender, and each Lender shall be deemed
to have acquired from the Issuing Lender, a participation in such Letter of
Credit equal to such Lender's Pro Rata Share of the aggregate amount available
to be drawn under such Letter of Credit. In consideration and in furtherance of
the foregoing, each Lender hereby absolutely and unconditionally agrees to pay
to the Agent, for the account of the Issuing Lender, such Lender's applicable
Pro Rata Share of each LC Disbursement made by the Issuing Lender and not
reimbursed by Borrower on the date due as provided in paragraph (5) of this
Section, or of any reimbursement payment in respect of any Letter of Credit
required to be refunded to Borrower for any reason. Each Lender acknowledges and
agrees that its obligation to acquire participations pursuant to this paragraph
in respect of Letters of Credit is absolute and unconditional, provided that the
Issuing Lender has complied with the terms hereof in connection therewith, and
shall not be affected by any circumstance whatsoever, including any amendment,
renewal or extension of any Letter of Credit or the occurrence and continuance
of a Default or Event of Default or any subsequent reduction or termination of
the Revolving Loan Commitments, and that each such payment shall be made without
any offset, abatement, withholding or reduction whatsoever.

                  (5)      If the Issuing Lender shall make any LC Disbursement
in respect of a Letter of Credit, the Borrower shall reimburse the Issuing
Lender in respect of such LC Disbursement by paying to the Agent for the account
of the Issuing Lender an amount equal to such LC Disbursement not later than
1:00 p.m. (Atlanta time), on (i) the Business Day that the Borrower receives
notice of such LC Disbursement, if such notice is received prior to 1:00 p.m.
(Atlanta time), or (ii) the Business Day immediately following the day that the
Borrower receives such notice, if such notice is not received prior to such
time, provided that Borrower may, subject to the conditions to borrowing set
forth herein, request that such payment be financed with a Revolving Loan in an
equivalent amount and, to the extent so financed,


                                      -4-

Borrower's obligation to make such payment shall be discharged and replaced by
the resulting Revolving Loan. If Borrower fails to make such payment when due,
Agent shall notify each Lender of the applicable LC Disbursement and the payment
then due from the Borrower in respect thereof, and such Lender shall pay to the
Agent its Pro Rata Share of the payment then due from Borrower, in the same
manner as provided herein with respect to Revolving Loans made by such Lender,
and Agent shall promptly pay to the Issuing Lender the amounts so received by it
from the Lenders. Promptly following receipt by Agent of any payment from
Borrower pursuant to this paragraph, Agent shall distribute such payment to the
Issuing Lender or, to the extent that the Lenders have made payments pursuant to
this paragraph to reimburse the Issuing Lender, then to such Lenders and the
Issuing Lender as their interests may appear. Any payment made directly by a
Lender pursuant to this paragraph to reimburse the Issuing Lender for any LC
Disbursement shall not constitute a Loan and, in any event, shall not relieve
Borrower of its obligation to reimburse such LC Disbursement.

                  (6)      (i) Borrower's obligation to reimburse LC
Disbursements as provided in paragraph (5) of this Section shall be absolute,
unconditional and irrevocable, and shall be performed strictly in accordance
with the terms hereof under any and all circumstances whatsoever, irrespective
of (A) any lack of validity or enforceability of any Letter of Credit, or any
term or provision therein, (B) any draft or other document presented under a
Letter of Credit proving to be forged, fraudulent or invalid in any respect or
any statement therein being untrue or inaccurate in any respect, (C) payment by
the Issuing Lender under a Letter of Credit against presentation of a draft or
other document that does not comply strictly with the terms of such Letter of
Credit and (D) any other event or circumstance whatsoever, whether or not
similar to any of the foregoing, that might, but for the provisions of this
Section, constitute a legal or equitable discharge of Borrower's obligations
hereunder.

                  (7)      Neither the Agent, the Lenders nor the Issuing Lender
shall have any liability or responsibility by reason of or in connection with
the issuance or transfer of any Letter of Credit by the Issuing Lender or any
payment or failure to make any payment thereunder (irrespective of any of the
circumstances referred to in the preceding sentence), or any error, omission,
interruption, loss or delay in transmission or delivery of any draft, notice or
other communication under or relating to any Letter of Credit (including any
document required to make a drawing thereunder), any error in interpretation of
technical terms or any consequence arising from causes beyond the control of the
Issuing Lender; provided that the foregoing shall not be construed to excuse the
Issuing Lender from liability to Borrower to the extent of any direct damages
(as opposed to consequential damages, claims in respect of which are hereby
waived by Borrower to the extent permitted by applicable law) suffered by the
Borrower that are caused by the Issuing Lender's gross negligence or willful
misconduct when determining whether drafts and other documents presented under a
Letter of Credit comply with the terms thereof. Subject in all respects to the
foregoing, the parties hereto expressly agree that:

                  (a)      the Issuing Lender may accept documents that appear
         on their face to be in substantial compliance with the terms of a
         Letter of Credit without responsibility for further investigation,
         regardless of any notice or information to the contrary, and may make
         payment upon presentation of documents that appear on their face to be
         in substantial compliance with the terms of such Letter of Credit;


                                      -5-
<PAGE>   10

                  (b)      the Issuing Lender shall have the right, in its sole
         discretion, to decline to accept such documents and to make such
         payment if such documents are not in strict compliance with the terms
         of such Letter of Credit; and

                  (c)      this paragraph (7) shall establish the standard of
         care to be exercised by the Issuing Lender when determining whether
         drafts and other documents presented under a Letter of Credit comply
         with the terms thereof (and the parties hereto hereby waive, to the
         extent permitted by applicable law, any standard of care inconsistent
         with the foregoing).

                  (8)      The Issuing Lender shall, promptly following its
receipt thereof, examine all documents purporting to represent a demand for
payment under any Letter of Credit. The Issuing Lender shall promptly notify
Agent and Borrower by telephone (confirmed by telecopy) of such demand for
payment and whether the Issuing Lender has made or will make an LC Disbursement
thereunder; provided that any failure to give or delay in giving such notice
shall not relieve Borrower of its obligation to reimburse the Issuing Lender and
the Lenders with respect to any such LC Disbursement.

                  (9)      If the Issuing Lender shall make any LC Disbursement
in respect of any Letter of Credit, then, unless, Borrower shall reimburse the
Issuing Lender for such LC Disbursement in full on the date such LC Disbursement
is made, the unpaid amount thereof shall bear interest, for each day from and
including the date such LC Disbursement is made to but excluding the date that
Borrower reimburses such LC Disbursement, at the rate per annum then applicable
to Revolving Loans. Interest accrued pursuant to this paragraph shall be for the
account of the Issuing Lender, except that interest accrued on and after the
date of payment by any Lender pursuant to paragraph (5) of this Section to
reimburse the Issuing Lender shall be for the account of such Lender to the
extent of such payment.

                  (10)     If either (i) a Default or Event of Default shall
occur and be continuing and the Borrower receives notice from the Agent or the
Requisite Lenders demanding the deposit of cash collateral pursuant to this
paragraph, Borrower shall immediately deposit with the Issuing Lender an amount
in cash equal to the LC Exposure on such date; provided that the obligation to
deposit cash collateral in an amount equal to the LC Exposure shall become
effective immediately, and such deposit shall become immediately due and
payable, without demand or other notice of any kind, upon the occurrence of any
Event of Default described in clauses (F) or (G) of Section 6.1. Such deposit
shall be held by the Agent as Collateral in the first instance for the LC
Exposure hereunder and thereafter for the payment of any other Obligations of
the Loan Parties hereunder.

                  (C)      Notes. Borrower shall execute and deliver to each
Lender on the Closing Date, a New Note to evidence such Lender's Pro Rata Share
of the Revolving Loans, such Note to be in the principal amount of such Lender's
Revolving Loan Commitment. Each such Note shall supersede and replace, as to the
Lender receiving same, any "Note" heretofore issued to such Lender pursuant to
the Existing Credit Agreement. In the event of an assignment under subsection
8.1, Borrower shall, upon surrender of the assigning Lender's Notes, issue new
Notes


                                      -6-
<PAGE>   11

to reflect the interests of the assigning Lender, if any, and the Person to
which interests are to be assigned.

                  1.2      Interest and Related Fees.

                  (A)      Loans shall bear interest at the rates set forth in
either paragraphs (1) or (2) below:

                  (1)      Unless Borrower elects otherwise in respect of any
Loans pursuant to paragraph (2) below, all Loans shall bear interest at the sum
of the Base Rate plus the Applicable Margin. As used herein, (i) "Base Rate"
means a variable rate of interest equal to the greater of the Prime Rate or (B)
the sum of the Federal Funds Effective Rate plus one-half of one percent (1/2%)
per annum; and (ii) "Base Rate Loans" means Loans bearing interest at rates
determined by reference to the Base Rate plus the Applicable Margin. Each such
determination by Agent of the Base Rate, in the absence of manifest error, shall
be binding and conclusive on all parties hereto.

                  (2)      Provided no Default or Event of Default then exists,
Borrower may, on or after the third (3rd) Business Day after the Closing Date,
request that Loans be made as LIBOR Loans and that outstanding portions of any
Loans be converted to LIBOR Loans. Any such request, which must be made (if at
all) in writing in the applicable Notice of Borrowing, shall pertain to Loans in
an aggregate minimum amount of Two Million Dollars ($2,000,000) and integral
multiples of Five Hundred Thousand Dollars ($500,000) in excess thereof. Once
given, a LIBOR Loan request shall be irrevocable and Borrower shall be bound
thereby. "LIBOR" means, for each Interest Period, a rate per annum equal to: (a)
the rate of interest determined by Agent at which deposits in U.S. dollars
approximately equal in principal amount to or comparable to the amount of a
given LIBOR Loan for a term equal or comparable to the relevant Interest Period
as reported on Telerate Page 3750 at approximately 11:00 a.m. (London time) on
that Business Day which is two (2) Business Days prior to the first day of such
Interest Period; provided, however, that (i) if two or more such offered rates
appear on such page in respect of the foregoing, the arithmetic mean of such
rates shall be used, and (ii) if Telerate ceases to provide LIBOR quotations,
such rate shall be the rate of interest at which comparable deposits in U.S.
dollars are offered as of the determination date by The Chase Manhattan Bank (or
any successor entity) to prime banks in the London interbank market; divided by
(b) a number equal to 1.0 minus the aggregate (but without duplication) of the
rates (expressed as a decimal fraction) of reserve requirements in effect on the
day which is two (2) Business Days prior to the beginning of such Interest
Period (including, without limitation, basic, supplemental, marginal and
emergency reserves under any regulations of the Board of Governors of the
Federal Reserve System or other governmental authority having jurisdiction with
respect thereto, as now and from time to time in effect) for Eurocurrency
funding (currently referred to as "Eurocurrency Liabilities" in Regulation D of
such Board) which are required to be maintained by a member bank of the Federal
Reserve System; such rate to be rounded upward to the next whole multiple of
one-sixteenth of one percent (.0625%); and "LIBOR Loans" means Loans bearing
interest at rates determined by reference to LIBOR plus the Applicable Margin.
Each such determination of LIBOR by Agent, in the absence of manifest error,
shall be binding and conclusive on all parties hereto.


                                      -7-
<PAGE>   12

Each LIBOR Loan may be obtained for periods of one (1) month, two (2) months,
three (3) or six (6) months (each being an "Interest Period"), at the Borrower's
option. With respect to LIBOR Loans: (a) the Interest Period will commence on
the date that the LIBOR Loan is made or the date on which a Base Rate Loan is
converted into a LIBOR Loan, as applicable, or in the case of immediately
successive Interest Periods, each successive Interest Period shall commence on
the day on which the next preceding Interest Period expires, (b) if the Interest
Period expires on a day that is not a Business Day, then it will expire on the
next Business Day (or, if such next Business Day is in the next calendar month,
on the preceding Business Day), and (c) no Interest Period shall extend beyond
the Expiry Date in any event. Upon the expiration of an Interest Period, in the
absence of a new LIBOR Loan request submitted to Agent not less than three (3)
Business Days prior to the end of such Interest Period, any LIBOR Loan then
maturing shall be automatically converted to a Base Rate Loan. There may be no
more than six (6) LIBOR Loans outstanding at any one time. Loans which are not
made the subject of a LIBOR Loan request shall be made (or continued) as Base
Rate Loans.

If the introduction of, or any change in the interpretation of, any law, rule,
or regulation, in each case, occurring after the Closing Date, would increase
the cost to any Lender of making or maintaining a LIBOR Loan, then Agent, on
behalf of all affected Lenders, shall submit a certificate to Borrower
demonstrating in reasonable detail the calculation of the increased cost and
requiring payment thereof to Agent for the benefit of the affected Lenders
within ten (10) days after the date of the certificate. Each Lender shall use
reasonable efforts to reduce or eliminate any claim for compensation pursuant to
this paragraph, including but not limited to designating a different Lending
Office for its making of LIBOR Loans if such designation will avoid the need
for, or reduce the amount of, such claim and will not, in the reasonable
judgment of such Lender, be materially disadvantageous to such Lender or result
in an increase in the aggregate amount payable by the Borrower.

Any Obligations other than the Loans, including without limitation, any accrued
interest, fees or reimbursable expenses, which are not paid when due, shall
themselves bear interest at the Base Rate plus the Applicable Margin, until
fully paid and satisfied, subject, however, to subsections (E) and (F) below,
and except as otherwise may be expressly provided in any Loan Document(s)
evidencing or giving rise to such Obligations.

                  (B)      Unused Revolving Loan Fees. Unless and until the
Revolving Loan Commitments are terminated, Borrower shall pay Agent, for the
benefit of all Lenders committed to make Revolving Loans (based upon their
respective Pro Rata Shares thereof), a fee in an amount equal to (i) (a) the
total of the Revolving Loan Commitments as in effect on the first day of each
calendar quarter (except that the first such calculation shall be based on the
total of the Revolving Loan Commitments as in effect on the Closing Date) less
(b) the average daily balance of the Revolving Loans and LC Exposure computed
for the calendar quarter (or portion thereof) in question multiplied by (ii) the
Applicable Margin (pertaining to "Unused Loan Fees"). Such fee is to be paid
quarterly in arrears on the first day of each calendar quarter for the preceding
calendar month, or portion thereof, commencing on the first of such days
succeeding the Closing Date.


                                      -8-
<PAGE>   13

                  (C)      Amendment Fee. On the Closing Date, Borrower shall
pay to Agent, for the benefit of all Lenders, to be allocated among them, based
on their respective Pro Rata Shares of the Commitments as of the Closing Date,
an amendment fee of Fifty Thousand Dollars ($50,000).

                  (D)      Letter of Credit Fees. Borrower agrees to pay with
respect to Letters of Credit outstanding hereunder the following fees:

                  (i)      to Agent for the account of each Lender a
         participation fee with respect to its participation in each "standby"
         Letter of Credit, which shall be equal to the product of (i) the rate
         per annum equal to the then Applicable Margin used in determining
         interest on LIBOR Loans (regardless whether then available), times (ii)
         such Lender's LC Exposure in respect of such standby Letter of Credit,
         payable in advance upon issuance of such Letter of Credit;

                  (ii)     to Agent for the account of each Lender a
         participation fee with respect to its participations in "commercial"
         Letters of Credit, which shall accrue at a rate per annum equal to the
         then Applicable Margin used in determining interest on LIBOR Loans
         (regardless whether then available) on the average daily amount of such
         Lender's LC Exposure (excluding any portion thereof attributable to
         unreimbursed LC Disbursements) during the period from and including the
         Closing Date to but excluding the later of the date on which such
         Lender's Revolving Loan Commitment terminates and the date on which
         there shall no longer be any such Letters of Credit outstanding
         hereunder, payable quarterly in arrears, on each January 1, April 1,
         and October 1 hereafter and at maturity; and

                  (iii)    to the Issuing Lender (x) a fronting fee for its own
         account, in amounts and at times separately agreed between Borrower and
         the Issuing Lender, and (y) the Issuing Lender's standard fees with
         respect to the issuance, amendment, renewal or extension of any Letter
         of Credit or the processing of drawings thereunder.

All participation fees and fronting fees shall be computed on the basis of a
year of 360 days and shall be payable for the actual number of days elapsed
(including the first day but excluding the last day).

                  (E)      Agent's and Arranger's Fees. Borrower shall also pay
to each of the Agent and Arranger, for its own account, such fees as are set
forth in the Fee Letter at the time or times specified therein.

                  (F)      Computation of Interest and Related Fees; Interest
Payment Dates. Interest on all Loans and all other Obligations and any fees set
forth in this subsection 1.2 shall be calculated daily on the basis of a three
hundred sixty (360) day year for the actual number of days elapsed in the period
during which it accrues. The date of funding of a Base Rate Loan and the first
day of an Interest Period with respect to a LIBOR Loan shall be included in the
calculation of interest. The date of payment of a Base Rate Loan and the last
day of an Interest Period with respect to a LIBOR Loan shall be excluded from
the calculation of interest. If a


                                      -9-
<PAGE>   14

Loan is repaid on the same day that it is made, one (1) day's interest shall be
charged. Interest on all Base Rate Loans shall be payable in arrears on the
first day of each calendar month and on the Expiry Date, whether by acceleration
or otherwise. Interest on LIBOR Loans shall be payable in arrears on the first
day of each calendar month, at the end of each Interest Period and on the Expiry
Date (whether by acceleration or otherwise). Such first day of each calendar
month shall be excluded in calculating the amount of interest payable on such
day, and be included in calculating the amount of interest payable on the next
succeeding interest payment date.

                  (G)      Default Rate of Interest. After the occurrence of any
Event of Default and for so long as it continues, all Loans and other
Obligations shall bear interest at a rate that is two percent (2%) in excess of
the rates otherwise payable under this Agreement. Furthermore, during any period
in which any Default or Event of Default has occurred and is continuing, as the
Interest Periods for LIBOR Loans then in effect expire, such Loans shall be
converted into Base Rate Loans and the LIBOR election provided in Section
1.2(A)(2) will not be available to Borrower so long as such Default or Event of
Default is continuing.

                  (H)      Excess Interest. Under no circumstances will the rate
of interest chargeable in respect of any Obligations be in excess of the maximum
amount permitted by law. If any excess interest is charged and paid in error,
then the excess amount will be promptly refunded to Borrower.

                  (I)      LIBOR Breakage Fee. In the event of any payment of a
LIBOR Loan on any day that is not the last day of the Interest Period applicable
thereto (regardless of the source of such prepayment and whether voluntary, by
acceleration or otherwise), Borrower shall pay Agent, for the benefit of all
affected Lenders, an amount (the "LIBOR Breakage Fee") equal to the amount of
any losses, expenses and liabilities (including, without limitation, any loss
(including interest paid) sustained by each such affected Lender in connection
with the re-employment of such funds) that any such affected Lender may sustain
as a result of the payment of such LIBOR Loan on a day that is not the last day
of the Interest Period applicable thereto. Agent, on behalf of all affected
Lenders, shall submit a certificate to Borrower demonstrating in reasonable
detail the calculation of any LIBOR Breakage Fee and requiring payment thereof
to Agent for the benefit of the affected Lenders within ten (10) days after the
date of such certificate.

                  1.3      Payments and Prepayments.

                  Payments. All payments by Borrower of the Obligations shall be
made in same day funds and delivered to Agent, for the benefit of Agent and
Lenders, as applicable, by wire transfer to such account and place as Agent may
from time to time designate. Borrower shall receive credit on the day of receipt
for funds received by Agent by 2:00 p.m. (Atlanta time). In the absence of
timely receipt, such funds shall be deemed to have been paid on the next
Business Day. Unless any payment owing hereunder is prescribed to be due on a
date certain, such payment shall be due and payable within ten (10) days after
Borrower's receipt of written demand therefor from Agent or Requisite Lenders,
as the case may be. Whenever any payment to be made hereunder shall be stated to
be due on a day that is not a Business Day, the payment


                                      -10-
<PAGE>   15

may be made on the next succeeding Business Day and such extension of time shall
be included in the computation of the amount of interest and fees due hereunder.
Borrower hereby authorizes and directs Lenders to make Revolving Loans, on the
basis of their Pro Rata Shares, for the payment of interest, fees and expenses
reimbursable to Lenders or Agent, if and to the extent that such Obligations are
not paid by Borrower when due, provided that Lenders shall have no obligation to
do so.

                  1.4      Term of the Agreement. All Commitments shall cease
and all Obligations shall become due and payable on the Expiry Date, unless any
earlier date is elsewhere expressly prescribed herein or in any Loan Document
with respect thereto, in which event such earlier date shall control. Upon such
date and following repayment in full of all such Obligations, this Agreement
will terminate. Notwithstanding any such termination, however, unless and until
all such Obligations have been fully paid and satisfied (excepting therefrom any
constituting at the time contingent indemnity obligations arising hereunder),
Agent, for the benefit of Agent and Lenders, shall be entitled to retain the
security interests in the Collateral granted under the Security Documents and
the ability to exercise all rights and remedies available under the Loan
Documents and applicable laws.

                  1.5      Loan Accounts. Agent will maintain loan account
records for (a) all Loans, Letters of Credit, interest charges and payments
thereof, (b) the charging and payment of all fees, costs and expenses and (c)
all other debits and credits pursuant to this Agreement and the other Loan
Documents. The balance in the loan accounts shall be presumptive evidence of the
amounts due and owing to Lenders (absent manifest error), provided that any
failure by Agent so to record shall not limit or affect the Borrower's
obligation to pay. Within ten (10) days after the first day of each calendar
month, Agent shall provide a statement to Borrower for each loan account setting
forth the principal of each account and interest due thereon. Borrower may
deliver a written objection within thirty (30) days after receipt of such
statement; otherwise, such statement will be conclusive evidence of the
Obligations therein stated absent manifest error. Unless a Default or Event of
Default has occurred and is continuing, Borrower shall have the right to direct
the application of any and all payments made on the Obligations (including any
made from funds withdrawn from the Dominion Account). During the continuance of
any Default or Event of Default, Borrower irrevocably waives the right to direct
the application of any and all such payments and Borrower hereby irrevocably
agrees that Agent shall have the continuing exclusive right to apply and reapply
payments in any manner it deems appropriate.

                  1.6      Capital Adequacy and Other Adjustments. In the event
that the adoption after the date hereof of any law, treaty, governmental (or
quasi-governmental) rule, regulation, guideline or order regarding capital
adequacy, reserve requirements (other than reserve requirements taken into
account in calculating LIBOR) or similar requirements or compliance by any
Lender or any corporation controlling such Lender with any request or directive
first made after the Closing Date regarding capital adequacy, reserve
requirements or similar requirements (whether or not having the force of law and
whether or not failure to comply therewith would be unlawful) from any central
bank or governmental agency or body having jurisdiction does or shall have the
effect of increasing the amount of capital, reserves or other funds required to
be maintained by such Lender or any corporation controlling such Lender and
thereby reducing the rate of return on such Lender's or such corporation's
capital as a consequence of its obligations


                                      -11-
<PAGE>   16

hereunder, then Borrower shall from time to time within ten (10) days after
notice and demand from such Lender (together with the certificate referred to in
the next sentence and with a copy to Agent) pay to Agent, for the account of
such Lender, additional amounts sufficient to compensate such Lender for such
reduction. A certificate as to the amount of such cost and showing in reasonable
detail the basis of the computation of such cost submitted by such Lender to
Borrower and Agent shall be conclusive absent manifest error. Each Lender shall
use reasonable efforts to reduce or eliminate any claim for compensation
pursuant to this subsection, including but not limited to designating a
different Lending Office for the Loans if such designation will avoid the need
for, or reduce the amount of, such claim and will not, in the sole discretion of
such Lender, be materially disadvantageous to such Lender or result in an
increase in the aggregate amount payable by Borrower. The failure or delay of
any Lender to demand compensation pursuant hereto shall not constitute a waiver
of such Lender's right to demand such compensation; provided, however, that
Borrower shall not be required to compensate a Lender pursuant hereto for any
increased costs or reductions more than six (6) months prior to the date that
such demand for compensation is made (but if an event giving rise to such demand
for compensation has retroactive effect, then, the retroactive period shall be
tacked to such six (6) months period for purposes hereof).

                  1.7      Taxes.

                  (A)      No Deductions. Subject to subsection (C) below, any
and all payments or reimbursements made hereunder or under the Notes shall be
made free and clear of and without deduction for any and all taxes, levies,
imposts, deductions, charges or withholdings, and all liabilities with respect
thereto, excluding, however, taxes imposed on the net income of a Lender or
Agent (all such taxes, levies, imposts, deductions, charges or withholdings and
all liabilities with respect thereto, excluding, however, such taxes imposed on
net income, as hereinabove excepted therefrom herein "Tax Liabilities"). Subject
to subsection (C) below, and excluding any withholding required for taxes
imposed on the net income of a Lender or Agent, if Borrower shall be required by
law to deduct any such amounts from or in respect of any sum payable hereunder
to any Lender or Agent, then the sum payable hereunder shall be increased as may
be necessary so that, after making all required deductions, such Lender or Agent
receives an amount equal to the sum it would have received had no such
deductions been made.

                  (B)      Changes in Tax Laws. In the event that, subsequent to
the Closing Date, (1) any changes in any existing law, rule or regulation or in
the interpretation or application thereof, (2) any new law, rule or regulation
enacted or any interpretation or application thereof, or (3) compliance by Agent
or any Lender with any request or directive (whether or not having the force of
law) from any governmental authority, agency or instrumentality does or shall
subject Agent or any Lender to any tax on the recording, registration,
notarization or other formalization of the Loans or the Notes and the result of
any of the foregoing is to increase the cost to Agent or any such Lender of
making or continuing any Loan hereunder, as the case may be, or to reduce any
amount receivable hereunder, then, in any such case, Borrower shall promptly pay
to Agent or such Lender, upon its demand, any additional amounts necessary to
compensate Agent or such Lender, on an after-tax basis, for such additional cost
or reduced amount receivable, as determined by Agent or such Lender with respect
to this Agreement or the other Loan Documents. Before making any such demand,
Agent or such Lender shall designate


                                      -12-
<PAGE>   17

a different Lending Office if such designation will avoid the need for, or
reduce the amount of, such demand and will not, in the reasonable judgment of
Agent or such Lender, be otherwise materially disadvantageous to Agent, the
Lender or the Borrower in any respect. If Agent or such Lender becomes entitled
to claim any additional amounts pursuant to this subsection, it shall promptly
notify Borrower of the event by reason of which Agent or such Lender has become
so entitled. A certificate as to any additional amounts payable pursuant to the
foregoing sentence submitted by Agent or such Lender to Borrower and Agent shall
be rebuttably presumed to be correct. Such certificate shall set forth the
nature of the occurrence giving rise to such compensation, the additional amount
or amounts to be paid hereunder and the method by which such amount or amounts
were determined. The failure or delay of any Lender to demand compensation
pursuant hereto shall not constitute a waiver of such Lender's right to demand
such compensation; provided, however, that Borrower shall not be required to
compensate a Lender pursuant hereto for any additional amounts more than six (6)
months prior to the date that such demand for compensation is made (but if an
event giving rise to such demand for compensation has retroactive effect, then,
the retroactive period shall be tacked to such six (6) months period for
purposes hereof).

                  (C)      Foreign Lenders. Each Lender organized under the laws
of a jurisdiction outside the United States (a "Foreign Lender") as to which
payments to be made under this Agreement or under the Notes are exempt from
United States withholding tax or are subject to United States withholding tax at
a reduced rate under an applicable statute or tax treaty shall provide to
Borrower and Agent (1) a properly completed and executed Internal Revenue
Service Form 4224 or Form 1001 or other applicable form, certificate or document
prescribed by the Internal Revenue Service of the United States certifying as to
such Foreign Lender's entitlement to such exemption or reduced rate of
withholding with respect to payments to be made to such Foreign Lender under
this Agreement and under the Notes (a "Certificate of Exemption") or (2) a
letter from any such Foreign Lender stating that it is not entitled to any such
exemption or reduced rate of withholding (a "Letter of Non-Exemption"). Prior to
becoming a Lender under this Agreement and within fifteen (15) days after a
reasonable written request of Borrower or Agent from time to time thereafter,
each Foreign Lender that becomes a Lender under this Agreement shall provide a
Certificate of Exemption or a Letter of Non-Exemption to Borrower and Agent. If
a Foreign Lender is entitled to an exemption with respect to payments to be made
to such Foreign Lender under this Agreement (or to a reduced rate of
withholding) and does not provide a Certificate of Exemption to Borrower and
Agent within the time periods set forth in the preceding sentence, Borrower
shall withhold taxes from payments to such Foreign Lender at the applicable
statutory rates and Borrower shall not be required to pay any additional amounts
as a result of such withholding, provided that all such withholding shall cease
or decrease, as applicable, upon delivery by such Foreign Lender of a valid and
correct Certificate of Exemption to Borrower and Agent.

                  1.8      Optional Prepayment/Replacement of Lender in Respect
of Increased Costs. Within fifteen (15) days after receipt by Borrower of
written notice and demand from any Lender (an "Affected Lender") for payment of
additional costs as provided in subsection 1.2(A) or Section 1.6, provided no
Default or Event of Default then exists, Borrower may, at its option, notify
Agent and such Affected Lender of its intention to do one of the following:


                                      -13-
<PAGE>   18

                  (A)      Subject to compliance with Sections 1.9 and 8.1,
Borrower may obtain, at Borrower's expense, a replacement Lender ("Replacement
Lender") for such Affected Lender, which Replacement Lender shall be reasonably
satisfactory to Agent. In the event Borrower obtains a Replacement Lender within
ninety (90) days following notice of its intention to do so, the Affected Lender
shall sell and assign its Loans and delegate its obligations under each of its
Commitments to such Replacement Lender, provided that Borrower has reimbursed
such Affected Lender for its increased costs for which it is entitled to
reimbursement under this Agreement through the date of such sale and assignment;
or

                  (B)      In lieu of the foregoing, Borrower may prepay in full
all outstanding Obligations owed to such Affected Lender and terminate each of
such Affected Lender's Commitments, in which case the aggregate Commitments will
be reduced by the amount of such Commitments so terminated concurrently with the
prepayment referred to in the next sentence. Borrower shall, within ninety (90)
days following notice of its intention to do so, prepay in full all outstanding
Obligations owed to such Affected Lender (including such Affected Lender's
increased costs for which it is entitled to reimbursement under this Agreement
through the date of such prepayment), and terminate such Affected Lender's
obligations under its respective Commitments.

                  1.9      Voluntary Termination or Reduction of Certain
Commitments. Borrower may voluntarily terminate, or from time to time reduce,
the Commitments at its option, provided, however, that (i) any such termination
is accompanied by full prepayment of all Loans then outstanding under the
Commitments, (ii) any such reduction is in the minimum amount of One Million
Dollars ($1,000,000) and integral multiples of Five Hundred Thousand Dollars
($500,000) in excess thereof; and (iii) any such reduction is accompanied by
prepayment of Loans outstanding under the Commitments by that amount necessary
so that the Maximum Revolving Loan Balance is not exceeded (after giving effect
to such Commitment reduction). Borrower shall notify Agent of any election to
terminate or reduce its Commitments at least three (3) Business Days prior to
the intended effective date of such termination or reduction, specifying such
election and the effective date thereof. Promptly following receipt of any
notice, Agent shall advise the lenders of the contents thereof. Each notice
delivered by the Borrower pursuant to this Section shall be irrevocable, and any
termination or reduction of Commitments shall be permanent. Each reduction of
Commitments shall be made ratably among the applicable Lenders in accordance
with their respective Commitments being reduced.

                  1.10     Affiliate Guaranty.

                  (A)      The Guarantee. The Affiliate Guarantors hereby
jointly and severally guarantee to the Agent and the Lenders the prompt payment
in full when due (whether at stated maturity, by acceleration or otherwise) of
all Obligations (such Obligations herein called, collectively, the "Guaranteed
Obligations"), in each case strictly in accordance with the terms hereof. The
Affiliate Guarantors hereby further jointly and severally agree that if Borrower
shall fail to pay in full when due (whether at stated maturity, by acceleration
or otherwise) any of the Guaranteed Obligations, the Affiliate Guarantors will
promptly pay the same, without any demand or notice whatsoever, and that in the
case of any extension of time of payment or renewal of any of the Guaranteed
Obligations, the same will be promptly paid in full when due


                                      -14-
<PAGE>   19

(whether at extended maturity, by acceleration or otherwise) in accordance with
the terms of such extension or renewal.

                  (B)      Obligations Unconditional. The obligations of the
Affiliate Guarantors hereunder are absolute and unconditional, joint and
several, irrespective of the value, genuineness, validity, regularity or
enforceability of the obligations of Borrower under this Agreement, the Notes or
any other Loan Document or any substitution, release or exchange of any other
guarantee of or security for any of the Guaranteed Obligations, and, to the
fullest extent permitted by applicable law, irrespective of any other
circumstance whatsoever that might otherwise constitute a legal or equitable
discharge or defense of a surety or guarantor (other than, subject to clause (C)
below, full payment and satisfaction of all Guaranteed Obligations), it being
the intent of this Section that the obligations of the Affiliate Guarantors
hereunder shall be absolute and unconditional, joint and several, under any and
all circumstances. Without limiting the generality of the foregoing, it is
agreed that, to the extent permitted by applicable law, the occurrence of any
one or more of the following shall not alter or impair the liability of the
Affiliate Guarantors hereunder which shall remain absolute and unconditional as
described above:

                  (i)      at any time or from time to time, without notice to
         any of the Affiliate Guarantors, the time for any performance of or
         compliance with any of the Guaranteed Obligations shall be extended, or
         such performance or compliance shall be waived;

                  (ii)     any of the acts mentioned in any of the provisions of
         this Agreement or the Notes or any other agreement or instrument
         referred to herein or therein on the part of Borrower to be done shall
         fail to be done or be omitted;

                  (iii)    the maturity of any of the Guaranteed Obligations
         shall be accelerated, or any of the Guaranteed Obligations shall be
         modified, supplemented or amended in any respect, or any right under
         this Agreement or the Notes or any other Loan Document shall be waived
         or any other guarantee of any of the Guaranteed Obligations or any
         security therefor shall be released or exchanged in whole or in part or
         otherwise dealt with; or

                  (iv)     any lien or security interest granted to, or in favor
         of, the Agent as security for any of the Guaranteed Obligations shall
         fail to be perfected.

The Affiliate Guarantors hereby expressly waive diligence, presentment, demand
of payment, protest and all notices whatsoever, and any requirement that Agent
or any Lender exhaust any right, power or remedy or proceed against Borrower
under this Agreement or the Notes or any other Loan Document, or against any
other Person under any other Guaranty of, or security for, any of the Guaranteed
Obligations.

                  (C)      Reinstatement. The obligations of the Affiliate
Guarantors hereunder shall be automatically reinstated if and to the extent that
for any reason any payment by or on behalf of Borrower in respect of the
Guaranteed Obligations is rescinded or must be otherwise restored by any holder
of any of the Guaranteed Obligations, whether as a result of any proceedings in
bankruptcy or reorganization or otherwise and the Affiliate Guarantors jointly
and severally


                                      -15-
<PAGE>   20

agree that they will indemnify each Agent and Lender on demand for all
reasonable costs and expenses (including, without limitation, reasonable fees
and disbursements of legal counsel) incurred by Agent or such Lender in
connection with such rescission or restoration, including any such costs and
expenses incurred in defending against any claim alleging that such payment
constituted a preference, fraudulent transfer or similar payment under any
bankruptcy, insolvency or similar law.

                  (D)      Deferral of Subrogation. Each Affiliate Guarantor
hereby subordinates to Agent and the Lenders all rights of subrogation or
contribution against Borrower, whether arising by contract or operation of law
(including, without limitation, any such right arising under the Bankruptcy
Code) or otherwise by reason of any payment by it pursuant to the provisions
hereof until all Obligations (other than any constituting contingent indemnity
obligations) are fully paid and satisfied and all Commitments are terminated.

                  (E)      Remedies. The Affiliate Guarantors jointly and
severally agree that, as between the Affiliate Guarantors and Agent and Lenders,
the Guaranteed Obligations may be declared to be forthwith due and payable as
provided herein (and shall be deemed to have become automatically due and
payable in the circumstances provided herein) for purposes hereof,
notwithstanding any stay, injunction or other prohibition preventing such
declaration (or such obligations from becoming automatically due and payable) as
against Borrower and that, in the event of such declaration in accordance with
the terms hereof (whether or not due and payable by the Borrower) shall
forthwith become due and payable by the Affiliate Guarantors for purposes
hereof.

                  (F)      Instrument for the Payment of Money. Each Affiliate
Guarantor hereby acknowledges that its guaranty herein constitutes an instrument
for the payment of money.

                  (G)      Continuing Guaranty. The guaranty set forth herein is
a continuing guaranty, and shall apply to all Guaranteed Obligations, whenever
and howsoever arising.

                  (H)      Rights of Contribution. The Affiliate Guarantors
hereby agree, as between themselves, that if any Affiliate Guarantor shall
become an "Excess Funding Guarantor" (as defined below) by reason of the payment
by such Affiliate Guarantor of any Guaranteed Obligations, each other Affiliate
Guarantor shall, on demand of such Excess Funding Guarantor (but subject to the
next sentence), pay to such Excess Funding Guarantor an amount equal to such
Affiliate Guarantor's "Pro Rata Share" (as defined below and determined, for
this purpose, without reference to the properties, debts and liabilities of such
Excess Funding Guarantor) of the "Excess Payment" (as defined below) in respect
of such Guaranteed Obligations. The payment obligation of an Affiliate Guarantor
to any Excess Funding Guarantor under this Section shall be subordinate and
subject in right of payment to the prior payment in full of the obligations of
such Affiliate Guarantor under the other provisions of this Section 1.11 and
such Excess Funding Guarantor shall not exercise any right or remedy with
respect to such excess until payment and satisfaction in full of all such
obligations. For purposes hereof, (i) "Excess Funding Guarantor" means, in
respect of any Guaranteed Obligations, an Affiliate Guarantor that has paid an
amount in excess of its Pro Rata Share of such Guaranteed Obligations, (ii)
"Excess Payment" means, in respect of any Guaranteed Obligations, the amount
paid by an Excess


                                      -16-
<PAGE>   21

Funding Guarantor in excess of its Pro Rata Share of such Guaranteed Obligations
(iii) "Pro Rata Share" means, for any Affiliate Guarantor, the ratio (expressed
as a percentage) of (x) the amount by which the aggregate present fair saleable
value of all assets of such Affiliate Guarantor (excluding any shares of stock
of any other Affiliate Guarantor) exceeds the amount of all the debts and
liabilities of such Affiliate Guarantor (including contingent, subordinated,
unmatured and unliquidated liabilities, but excluding the obligations of such
Affiliate Guarantor hereunder and any obligations of any other Affiliate
Guarantor that have been guaranteed by such Affiliate Guarantor) to (y) the
amount by which the aggregate fair saleable value of all assets of all of the
Affiliate Guarantors exceeds the amount of all the debts and liabilities
(including contingent, subordinated, unmatured and unliquidated liabilities, but
excluding the obligations of the Affiliate Guarantor hereunder) of the Affiliate
Guarantors, determined (A) with respect to any Affiliate Guarantor that is a
party hereto on the Closing Date, as of the Closing Date, and (B) with respect
to any other Affiliate Guarantor, as of the date such Affiliate Guarantor
becomes an Affiliate Guarantor hereunder.

                  (I)      Limitation on Guaranteed Obligations. In any action
or proceeding involving any state corporate law, or any state or Federal
bankruptcy, insolvency, reorganization or other law affecting the rights of
creditors generally, if the obligations of the Affiliate Guarantors hereunder,
after giving effect to the contribution rights provided herein above, would
otherwise be held or determined to be void, invalid or unenforceable, or
subordinated to the claims of any other creditors, on account of the amount of
its liability hereunder, then, notwithstanding any other provision hereof to the
contrary, the amount of such liability shall, without any further action by any
Affiliate Guarantor, Agent, any Lender or any other Person, be automatically
limited and reduced to the highest amount that is valid and enforceable and not
subordinated to the claims of other creditors as determined in such action or
proceeding.


                                   SECTION 2
                              AFFIRMATIVE COVENANTS

                  Borrower covenants and agrees that so long as the Commitments
are in effect and until payment in full of all Obligations, unless Requisite
Lenders shall otherwise give their prior written consent, Borrower shall perform
and comply with, and shall cause each of the other Loan Parties to perform and
comply with, all covenants in this Section 2 applicable to such Person.

                  2.1      Compliance With Laws. Borrower will (a) comply with,
and will cause each of the Loan Parties to comply with, the requirements of all
applicable laws, rules, regulations and orders of any Governmental Authority as
now in effect and which may be imposed in the future in all jurisdictions in
which Borrower or the Loan Parties are now doing business or may hereafter be
doing business, noncompliance with which would reasonably be expected to have a
Material Adverse Effect, and (b) maintain or obtain, and will cause each of the
Loan Parties to maintain or obtain, all licenses, qualifications and permits now
held or hereafter required to be held by Borrower and its Subsidiaries, for
which the loss, suspension, revocation or failure to obtain or renew would
reasonably be expected to have a Material Adverse Effect. Without limiting the
generality of the foregoing, Borrower will cause all Loan Parties to
continuously hold all FCC Licenses and Franchises required for the operation of
their


                                      -17-
<PAGE>   22

respective businesses, including all Franchises required by the FCC or any state
Governmental Authority in connection with the ownership and operation of their
respective businesses, in any such case where the failure to hold any such FCC
License or Franchise, would reasonably be expected to have a Materially Adverse
Effect. Borrower will also cause all Loan Parties to comply in all material
respects with all applicable filing and operating requirements of all of such
FCC Licenses and Franchises, and any and all other regulations promulgated by
the FCC and state Governmental Authorities, including, as applicable, the "no
hazard" clearance determination issued by the FAA, the antenna structure
registration certificate issued by the FCC, and any state health permit or
public utility license, if required. The foregoing shall not preclude the
Borrower or any Loan Party from contesting any taxes or other payments claimed
to be owing at any time to any Governmental Authority, if they are being
diligently contested in good faith and if appropriate expense provisions have
been recorded (if and to the extent required in conformity with GAAP).

                  2.2      Maintenance of Properties; Insurance. Borrower will
maintain, and cause the Loan Parties to maintain, in good repair, working order
and condition (ordinary wear and tear excepted) all material properties used in
the respective businesses of Borrower and the Loan Parties and will make or
cause to be made all appropriate repairs, renewals and replacements thereof.
Borrower further will maintain and cause the Loan Parties to maintain, with
financially sound and reputable insurers, public liability, property damage and
business interruption insurance with respect to its business and properties and
the business and properties of the Loan Parties against loss or damage of the
kinds and in the amounts customarily carried or maintained by companies of
established reputation engaged in similar businesses and will deliver evidence
thereof to Agent. Borrower further shall cause Agent, pursuant to endorsements
and assignments and assignments in form and substance reasonably satisfactory to
be named as loss payee in the case of casualty insurance, additional insured in
the case of all liability insurance and assignee in the case of all business
interruption insurance. Without limiting the generality of the foregoing,
Borrower will cause each Loan Party to (x) maintain or cause to be maintained
flood insurance with respect to each Flood Hazard Property in amounts approved
by Agent, or provide evidence acceptable to Agent that such insurance is not
available and (y) maintain or cause to be maintained replacement value casualty
insurance on all tangible Collateral under such policies of insurance, in each
case with such insurance companies, in such amounts, with such deductibles, and
covering such terms and risks as are at all times satisfactory to the Agent in
its commercially reasonable judgment. Each such policy of insurance shall (A)
name the Agent for the benefit of the Lenders as an additional insured
thereunder as its interests may appear and (B) in the case of each business
interruption and casualty insurance policy, contain a loss payable clause or
endorsement, satisfactory in form and substance to the Agent that names Agent
for the benefit of the Lenders as the loss payee thereunder for any covered loss
and provides for at least thirty (30) days prior written notice to Agent of any
modifications or cancellation of such policy.

                  2.3      Inspections. Borrower shall permit any authorized
representatives of Agent to (i) visit and inspect any of the properties of
Borrower or any of the Loan Parties, including its and their financial and
accounting records, and to make copies and take extracts therefrom, (ii) to
discuss its and their affairs, finances and business with Borrower's and the
Loan Parties' officers or managers and certified public accountants, and (iii)
to visit any Collateral Location and inspect the Collateral, observe its use,
maintenance or storage, and


                                      -18-
<PAGE>   23

confirm Borrower's and the Affiliate Guarantors' compliance with the terms of
the Security Documents; in each case, at such reasonable times during normal
business hours as may be reasonably requested by Agent.

                  2.4      Corporate or Company Existence, Etc. Except as
otherwise may be expressly permitted by Section 3.6, Borrower will, and will
cause each of the Loan Parties to, at all times preserve and keep in full force
and effect its corporate or company existence and all rights and Franchises
material to its business.

                  2.5      Further Assurances. Borrower shall, and shall cause
each of the Loan Parties to, from time to time, execute such financing
statements, documents and reports as Agent or Requisite Lenders at any time may
reasonably request to evidence, perfect or otherwise implement the guaranties
and security for repayment of the Obligations contemplated by the Loan
Documents.

                  2.6      Pledge of Stock. On the Closing Date, in each case to
the extent not completed prior to the First Closing Date, (i) as to Borrower,
Parent shall, and (ii) as to all Subsidiaries (whether direct or indirect) of
Borrower existing on the Closing Date, and upon the establishment, creation or
acquisition thereof, as to each such Subsidiary established, created or acquired
subsequent to the Closing Date in accordance with Section 3.13 below, Borrower
shall, or (as the case may be) shall cause each of its Subsidiaries to, pledge
to Agent, as security for payment of the Obligations, pursuant to one or more
Pledge Agreements, all Equity Interests owned in Borrower by Parent or by
Borrower or any such Subsidiary in any such Subsidiaries of Borrower; provided,
however, that, notwithstanding the foregoing, if any such Subsidiary is a
Foreign Subsidiary, then (i) the foregoing pledge shall not be required unless
and until such Subsidiary's total assets exceed One Million Dollars ($1,000,000)
and (ii) the foregoing pledge, if required, shall be limited in any event to
sixty-five percent (65%) of the Equity Interests in such Subsidiary.

                  2.7      Conforming Leasehold Interests; Matters Relating to
Additional Real Property Collateral.

                  (A)      If any Loan Party acquires any Material Leasehold
Property subsequent to the Closing Date each of the Loan Parties shall use its
reasonable efforts (without requiring Loan Party to relinquish any material
rights or incur any material obligations or to expend more than a nominal amount
of money over and above the reimbursement, if required, of the landlord's
out-of-pockets costs, including attorneys' fees) to cause such Leasehold
Property to be a Conforming Leasehold Interest.

                  (B)      From and after the Closing Date, in the event that
(i) any Loan Party acquires any fee simple interest in real property or any
Material Leasehold Property, or the Agent determines in its sole discretion to
place a Mortgage on any Real Property Asset owned on the Closing Date by any
Loan Party (if a Mortgage was not placed on any such Real Property Asset as of
the Closing Date), or (ii) at the time any Person becomes a Subsidiary
Guarantor, such Person owns or holds any fee interest in real property or any
Material Leasehold Property, in either case excluding any such Real Property
Asset the encumbering of which requires the


                                      -19-
<PAGE>   24

consent of any applicable lessor or (in the case of clause (ii) above) any
then-existing senior lienholder, where the Loan Parties are unable to obtain
such lessor's or senior lienholder's consent (any such non-excluded Real
Property Asset described in the foregoing clause (i) or (ii) being a "Additional
Mortgaged Property"), such Loan Party shall deliver to Agent, as soon as
practicable after such Person acquires such Additional Mortgaged Property, but,
in any event within thirty (30) days thereafter, the following:

                  (i)      Additional Mortgages. A fully executed and notarized
         Mortgage (an "Additional Mortgage"), in proper form for recording in
         all appropriate places in all applicable jurisdictions, encumbering the
         interest of such Loan Party in such Additional Mortgaged Property;

                  (ii)     Recorded Leasehold Interests. In the case of any
         Additional Mortgaged Property consisting of a Leasehold Property,

         Agreement with respect thereto and where required by the terms of any
         lease, the consent of the mortgagee, ground lessor or other party and
         (b) evidence that such Leasehold Property is a Recorded Leasehold
         Interest;

                  (iv)     Matters Relating to Flood Hazard Properties. (A)
         Evidence as to whether any Additional Mortgaged Property is a Flood
         Hazard Property and (B) if such Additional Mortgaged Property is a
         Flood Hazard Property, evidence that the applicable Loan Party, has
         obtained flood insurance with respect to each Flood Hazard Property in
         amounts approved by Agent, or evidence acceptable to Agent that such
         insurance is not available;

                  (v)      Title Insurance. (A) If required by Agent, ALTA
         mortgagee title insurance policies or unconditional commitments
         therefor (the "Additional Mortgage Policies') issued by the Title
         Company with respect to the Additional Mortgaged Property, in an amount
         satisfactory to Agent, insuring fee simple title to, or a valid
         leasehold interest in, each such Additional Mortgaged Property vested
         in such Loan Party and assuring Agent that such Additional Mortgage
         creates a valid and enforceable first priority mortgage Lien on such
         Additional Mortgaged Property, subject only to such standard exceptions
         as may be reasonably acceptable to Agent and Permitted Encumbrances,
         which Additional Mortgage Policy (I) shall include all endorsement for
         matters reasonably requested by Agent and (II) shall provide for
         affirmative insurance and such reinsurance as the Agent may reasonably
         request, all of the foregoing to be in form and substance reasonably
         satisfactory to Agent; and (B) evidence satisfactory to Agent that such
         Loan Party has (I) delivered to the Title Company all certificates and
         affidavits required by the Title Company m connection with the issuance
         of the Additional Mortgage Policy and (II) paid to the Title Company or
         to the appropriate Governmental Authorities all expenses and premiums

created or acquired hereafter either pursuant to an Approved Acquisition or
otherwise with the prior written consent of the Requisite Lenders, shall, upon
its establishment, creation or acquisition, become an Affiliate Guarantor
hereunder by its execution and delivery to Agent of a Joinder Agreement in

Subsidiary owned by it, nor permit any Subsidiary to issue any shares of stock
of any class whatsoever to any Person other than to a Loan Party. The Loan
Parties will take such action from time to time as shall be necessary to ensure
that the percentage of the Equity Interests of any class or character owned by
it in any Subsidiary on the Closing Date hereof (or, in the case of any newly
formed or newly acquired Subsidiary, on the date of formation or acquisition) is
not any time decreased, other than by reason of transfers to another Loan Party.
In the event that any additional Equity Interests shall be issued by Borrower or
any Subsidiary, the respective holder of such Equity Interests shall forthwith
deliver to Agent pursuant to a Pledge Agreement any certificates evidencing such
Equity Interests, accompanied by undated stock powers executed in blank and to
take such other action as Agent shall request to perfect the security interest
created therein pursuant to such Pledge Agreement.

                                      -39-
<PAGE>   44

contingent, based on or arising from the generation, storage, transport,
handling or disposal of Hazardous Materials by any Loan Party, or relating to
any site or facility owned, operated or leased by any Loan Party, which claims
or liabilities (insofar as they are payable by any Loan Party after deducting
any portion thereof which is reasonably expected to be paid by other
creditworthy Persons jointly and severally liable therefor), in the judgment of
the Requisite Lenders are reasonably likely to be determined adversely to any
Loan Party, and the amount thereof is, singly or in the aggregate, is reasonably
likely to have a Material Adverse Effect;

                  (R) Subordinated Indebtedness. Any default occurs in respect
of any Subordinated Indebtedness and such default continues beyond any grace or
cure period prescribed in regard thereto; or any Loan Party or any Person (other
than Agent or Lenders) party to a subordination agreement favoring Agent or
Lenders in respect thereof (including any as to which Agent or Lenders are third
party beneficiaries) fails to observe or perform any term, covenant or condition
of such subordination; or

                  6.2 Suspension of Commitments. Upon the occurrence of any
Event of Default, each Lender, at the direction of Agent or Requisite Lenders,
without notice or demand, may immediately cease making additional Loans and
cause its obligation to lend its Pro Rata Share of the Commitments to be
suspended, in whole or in part, as so directed; provided, however, that, in the
case of any such Event of Default, if the subject condition or event is


                                      -40-
<PAGE>   45

thereafter waived or otherwise removed by Requisite Lenders, any suspended
portion of the Commitments shall be reinstated.

                  6.3 Acceleration. Upon the occurrence of any Event of Default
described in the foregoing subsections 6.1(F) or 6.1(G), the unpaid principal
amount of and accrued interest and fees on the Loans and all other Obligations
shall automatically become immediately due and payable, without presentment,
demand, protest, notice of intent to accelerate, notice of acceleration or other
requirements of any kind, all of which are hereby expressly waived by Borrower,
and the Commitments shall thereupon terminate. Upon the occurrence and during
the continuance of any other Event of Default, Agent may, and upon written
demand by Requisite Lenders shall, by written notice to Borrower declare all or
any portion of the Loans and all or some of the other Obligations to be, and the
same shall forthwith become, immediately due and payable together with accrued
interest thereon, and the Commitments shall thereupon terminate.

                  6.4 Performance by Agent. If Borrower shall fail to perform
any covenant, duty or agreement contained in any of the Loan Documents, Agent
may perform or attempt to perform such covenant, duty or agreement on behalf of
Borrower after the expiration of any cure or grace periods set forth herein if
such failure constitutes an Event of Default. In such event, Borrower shall, at
the request of Agent, promptly pay any reasonable amount expended by Agent, in
good faith, in such performance or attempted performance to Agent, together with
interest thereon at the highest rate of interest in effect upon the occurrence
of an Event of Default as specified in subsection 1.2(G) from the date of such
expenditure until paid. Notwithstanding the foregoing, it is expressly agreed
that Agent shall not have any liability or responsibility for the performance of
any obligation of Borrower under this Agreement or any other Loan Document, and
that Borrower shall have no obligation to reimburse Agent for expenses incurred
as a result of, or in connection with, Agent's gross negligence or willful
misconduct.

                  (B) The representations and warranties contained in Section 5

                          ASSIGNMENT AND PARTICIPATION

                  8.1 Assignments and Participations in Loans and Notes. Each
Lender may assign, subject to the terms of a Lender Addition Agreement, its
rights and delegate its obligations under this Agreement to another Person,
provided that, unless the assignment is to an Affiliate of the assigning Lender
or to another Lender, such Lender shall first obtain the written consent (not to
be unreasonably withheld, conditioned or delayed) of Agent, and, provided no
Default or Event of Default has occurred which is then continuing, Borrower; (b)
the Commitments (and Loans) being assigned must include all types of Commitments
and Loans and equal Pro Rata Shares of each type of Commitment and Loans; (c)
the principal amount of the Commitments and Loans being assigned shall in no
event be less than the lesser of (i) Five Million Dollars ($5,000,000) and (ii)
the entire amount of such Lender's Pro Rata Shares of such Commitments and
Loans; (d) any assignee that is a foreign bank shall have complied with Section
1.7(A) hereof; and (e) upon the consummation of each such assignment, the
assigning Lender shall pay Agent an administrative fee of Three Thousand Five
Hundred Dollars ($3,500)



                                      -45-
<PAGE>   50

and any expenses reasonably incurred by Agent (or its legal counsel) in giving
effect to such assignment. The administrative fee referred to in clause (e) of
the preceding sentence shall not apply to an assignment from a Lender to an
Affiliate of such Lender. Upon the valid effectuation of an assignment
authorized under this subsection 8.1, the assignee shall become a Lender and
shall have, to the extent of such assignment, the same rights, benefits and
obligations as it would if it were an initial Lender hereunder. The assigning
Lender shall be relieved of its obligations hereunder with respect to its Pro
Rata Share of the Commitments and Loans, or portion thereof, validly assigned.

                  Each Lender (including Wachovia) may also sell participations
in all or any part of its Commitments and Loans to another Person, provided that
all amounts payable by Borrower hereunder shall be determined as if that Lender
had not sold such participation and the holder of any such participation shall
not be entitled to require such Lender to take or omit to take any action
hereunder.

                  Except as otherwise provided in this subsection 8.1, no Lender
shall, as between Borrower and that Lender, be relieved of any of its
obligations hereunder as a result of any sale, assignment, transfer or
negotiation of, or granting of a participation in, all or any part of the Loans,
the Notes or other Obligations owed to such Lender. Each Lender may furnish any
information concerning Borrower and its Subsidiaries in the possession of that
Lender from time to time to assignees and participants (including prospective
assignees and participants approved by Borrower), subject to the provisions of
Section 9.13 concerning confidentiality.

                  Borrower agrees that it will assist and cooperate with Agent
and any Lender in any manner reasonably requested by Agent or such Lender to
effect the sale of a participation or an assignment described above.

                  Agent shall provide Borrower with written notice of the name
and address of any new Lender after the date hereof.

                  Notwithstanding anything contained in this Agreement to the
contrary, so long as the Requisite Lenders shall remain capable of making LIBOR
Loans, no Person shall become a "Lender" hereunder unless such Person shall also
be capable of making LIBOR Loans.

                  8.2  Agent.

                  (A) Appointment. Each Lender hereby designates and appoints
Wachovia as its Agent under this Agreement and the other Loan Documents, and
each Lender hereby irrevocably authorizes Agent to take such action or to
refrain from taking such action on its behalf under the provisions of this
Agreement and the other Loan Documents and to exercise such powers as are set
forth herein or therein, together with such other powers as are reasonably
incidental thereto. Agent is authorized and empowered to amend, modify, or waive
any provisions of this Agreement or the other Loan Documents on behalf of
Lenders subject to the requirement that the consent of certain Lenders be
obtained in certain instances as provided in subsections 8.3 and 9.2. Agent
agrees to act as such on the express conditions contained in this


                                      -46-
<PAGE>   51

subsection 8.2 (other than subsections (G) and (H) below). The provisions of
this subsection 8.2 are solely for the benefit of Agent and Lenders and neither
Borrower nor any other Loan Party shall have any rights as a third party
beneficiary of any of the provisions hereof. In performing its functions and
duties under this Agreement, Agent shall act solely as agent of Lenders and does
not assume and shall not be deemed to have assumed any obligation toward or
relationship of agency or trust with or for Borrower or any other Loan Party.
Agent may perform any of its duties hereunder, or under the Loan Documents, by
or through its agents or employees.

                  (B) Nature of Duties. The duties of Agent shall be mechanical
and administrative in nature. Agent shall not have by reason of this Agreement a
fiduciary relationship in respect of any Lender. Nothing in this Agreement or
any of the Loan Documents, express or implied, is intended to or shall be
construed to impose upon Agent any obligations in respect of this Agreement or
any of the Loan Documents except as expressly set forth herein or therein. Each
Lender shall make its own independent investigation of the financial condition
and affairs of Borrower in connection with the extension of credit hereunder and
shall make its own appraisal of the creditworthiness of Borrower, and Agent
shall have no duty or responsibility, either initially or on a continuing basis,
to provide any Lender with any credit or other information with respect thereto
(other than as expressly required herein). If Agent seeks the consent or
approval of any Lenders to the taking or refraining from taking any action
hereunder, then Agent shall send notice thereof to each Lender. Agent shall
promptly notify each Lender any time that the Requisite Lenders have instructed
Agent to act or refrain from acting pursuant hereto.

                  (C) Rights, Exculpation, Etc. Neither Agent nor any of its
officers, directors, employees or agents shall be liable to any Lender for any
action taken or omitted by them hereunder or under any of the Loan Documents, or
in connection herewith or therewith, except that Agent shall be liable with
respect to its own gross negligence or willful misconduct. Agent shall not be
liable for any apportionment or distribution of payments made by it in good
faith and if any such apportionment or distribution is subsequently determined
to have been made in error the sole recourse of any Lender to whom payment was
due but not made, shall be to recover from other Lenders any payment in excess
of the amount to which they are determined to be entitled (and such other
Lenders hereby agree to return to such Lender any such erroneous payments
received by them). In performing its functions and duties hereunder, Agent shall
exercise the same care which it would in dealing with loans for its own account,
but Agent shall not be responsible to any Lender for any recitals, statements,
representations or warranties herein or for the execution, effectiveness,
genuineness, validity, enforceability, collectibility, or sufficiency of this
Agreement or any of the Loan Documents or the transactions contemplated thereby,
or for the financial condition of any Loan Party. Agent shall not be required to
make any inquiry concerning either the performance or observance of any of the
terms, provisions or conditions of this Agreement or any of the Loan Documents
or the financial condition of any Loan Party, or the existence or possible
existence of any Default or Event of Default. Agent may at any time request
instructions from Lenders with respect to any actions or approvals which by the
terms of this Agreement or of any of the Loan Documents Agent is permitted or
required to take or to grant, and if such instructions are promptly requested,
Agent shall be absolutely entitled to refrain from taking any action or to
withhold any approval and shall not be under any liability whatsoever to any
Person for refraining from any action or withholding any approval


                                      -47-
<PAGE>   52

under any of the Loan Documents until it shall have received such instructions
from Requisite Lenders or all of the Lenders, as applicable. Without limiting
the foregoing, no Lender shall have any right of action whatsoever against Agent
as a result of Agent acting or refraining from acting under this Agreement, the
Notes, or any of the other Loan Documents in accordance with the instructions of
Requisite Lenders.

                  (D) Reliance. Agent shall be entitled to rely, and shall be
fully protected in relying, upon any written or oral notices, statements,
certificates, orders or other documents or any telephone message or other
communication (including any writing, telex, telecopy or telegram) believed by
it in good faith to be genuine and correct and to have been signed, sent or made
by the proper Person, and with respect to all matters pertaining to this
Agreement or any of the Loan Documents and its duties hereunder or thereunder,
upon advice of counsel selected by it. Agent shall be entitled to rely upon the
advice of legal counsel, independent accountants, and other experts selected by
Agent in its sole discretion.

                  (E) Indemnification. Lenders will reimburse and indemnify
Agent for and against any and all liabilities, obligations, losses, damages,
penalties, actions, judgments, suits, costs, expenses (including, without
limitation, attorneys' fees and expenses), advances or disbursements of any kind
or nature whatsoever which may be imposed on, incurred by, or asserted against
Agent in any way relating to or arising out of this Agreement or any of the Loan
Documents or any action taken or omitted by Agent under this Agreement or any of
the Loan Documents, in proportion to each Lender's Pro Rata Share; provided,
however, that no Lender shall be liable for any portion of such liabilities,
obligations, losses, damages, penalties, actions, judgments, suits, costs,
expenses, advances or disbursements resulting from Agent's gross negligence or
willful misconduct. If any indemnity furnished to Agent for any purpose shall,
in the opinion of Agent, be insufficient or become impaired, Agent may call for
additional indemnity and cease, or not commence, to do the acts indemnified
against until such additional indemnity is furnished. The obligations of Lenders
under this subsection shall survive the payment in full of the Obligations and
the termination of this Agreement.

                  (F) Agent Individually. With respect to its obligations under
the Commitments, the Loans made by it, and the Notes issued to it, the Agent
shall have and may exercise the same rights and powers hereunder and is subject
to the same obligations and liabilities as and to the extent set forth herein
for any other Lender. The terms "Lenders" or "Requisite Lenders" or any similar
terms shall, unless the context clearly otherwise indicates, include the Agent
in its individual capacity as a Lender or one of the Requisite Lenders. The
Agent may lend money to, and generally engage in any kind of banking, trust or
other business with, any Loan Party as if it were not acting as Agent pursuant
hereto.

<PAGE>   53

                  (G) Successor Agent.

                  (1) Resignation. Agent may resign from the performance of all
its agency functions and duties hereunder at any time by giving at least thirty
(30) Business Days' prior written notice to Borrower and the Lenders. Such
resignation shall take effect upon the acceptance by a successor Agent of
appointment pursuant to clause (2) below or as otherwise provided below.

                  (2) Appointment of Successor. Upon any such notice of
resignation pursuant to clause (1) above, the Requisite Lenders shall appoint a
successor Agent. If a successor Agent shall not have been so appointed within
thirty (30) days, the retiring Agent shall then appoint a successor Agent from
among the Lenders who shall serve as Agent until such time, if any, as Requisite
Lenders appoint a successor Agent as provided above.

                  (3) Successor Agent. Upon the acceptance of any appointment as
Agent under the Loan Documents by a successor Agent, such successor Agent shall
thereupon succeed to and become vested with all the rights, powers, privileges
and duties of the retiring Agent, and the retiring Agent shall be discharged
from its duties and obligations under the Loan Documents. After any retiring
Agent's resignation as Agent under the Loan Documents, the provisions of this
subsection shall inure to its benefit as to any actions taken or omitted to be
taken by it while it was Agent under the Loan Documents.

                  (H) Collateral Matters.

                  (1) Release of Collateral. Lenders hereby irrevocably
authorize Agent, at its option and in its discretion, to release any Lien
granted to or held by Agent upon any property covered by the Security Documents
(i) upon termination of the Revolving Loan Commitment and payment and
satisfaction of all Obligations (other than contingent indemnification
Obligations not then due and payable); (ii) constituting property being sold or
disposed of if Borrower certifies to Agent that the sale or disposition is made
in compliance with the provisions of this Agreement, and Agent may rely in good
faith conclusively on any such certificate, without further inquiry (it being
understood that no release by Agent on any Inventory shall be necessary if such
Inventory is sold in the Ordinary Course of Business); or (iii) constituting
property leased to Borrower under a lease which has expired or been terminated
in a transaction permitted under this Agreement or is about to expire and which
has not been, and is not intended by Borrower to be, renewed or extended.

                  (2) Confirmation of Authority; Execution of Releases. Without
in any manner limiting Agent's authority to act without any specific or further
authorization or consent by Lenders, each Lender agrees to confirm in writing,
upon request by Agent or Borrower, the authority to release any property covered
by the Security Documents conferred upon Agent under clauses (i) through (iii)
of subsection 8.2(H)(1). Upon receipt by Agent of confirmation from the
requisite percentage of Lenders required by subsection 8.2(H)(1), if any, of its
authority to release or compromise any particular item or types of property
covered by the Security Documents, and upon at least ten (10) Business Days
prior written request by Borrower, Agent


                                      -49-
<PAGE>   54

shall (and is hereby irrevocably authorized by Lenders to) execute such
documents as may be necessary to evidence the release or compromise of the Liens
granted to Agent, for the benefit of Agent and Lenders, upon such Collateral,
provided that (i) Agent shall not be required to execute any such document on
terms which, in Agent's reasonable opinion, would expose Agent to liability or
create any obligation or entail any consequence other than the release or
compromise of such Liens without recourse or warranty, and (ii) such release or
compromise shall not in any manner discharge, affect or impair the Obligations
or any Liens upon (or obligations of any Loan Party, in respect of), all
interests retained by any Loan Party, including (without limitation) the
proceeds of any sale, all of which shall continue to constitute part of the
property covered by the Security Documents.

                  (3) Absence of Duty. Agent shall have no obligation whatsoever
to any Lender or any other Person to assure that the property covered by the
Security Documents exists or is owned by Borrower or is cared for, protected or
insured or has been encumbered or that the Liens granted to Agent have been
properly or sufficiently or lawfully created, perfected, protected or enforced
or are entitled to any particular priority, or to exercise at all or in any
particular manner or under any duty of care, disclosure or fidelity, or to
continue exercising, any of the rights, authorities and powers granted or
available to Agent in this subsection 8.2(H) or in any of the Loan Documents, it
being understood and agreed that in respect of the property covered by the
Security Documents or any act, omission or event related thereto, Agent may act
in any manner it may deem appropriate, in its discretion, given Agent's own
interest in property covered by the Security Documents as one of the Lenders and
that Agent shall have no duty or liability whatsoever to any of the other
Lenders, provided that Agent shall exercise the same care which it would in
dealing with loans for its own account.

                  (I) Agency for Perfection. Agent and each Lender hereby
appoint each other Lender as agent for the purpose of perfecting Agent's
security interest in assets which, in accordance with Article 9 of the Uniform
Commercial Code in any applicable jurisdiction, can be perfected only by
possession. Should any Lender (other than Agent) obtain possession of any such
Collateral, such Lender shall notify Agent thereof, and, promptly upon Agent's
request therefor, shall deliver such Collateral to Agent or in accordance with
Agent's instructions. Each Lender agrees that it will not have any right
individually to enforce or seek to enforce any Security Document or to realize
upon any collateral security for the Loans, it being understood and agreed that
such rights and remedies may be exercised only by Agent.

                  (J) Dissemination of Information. Agent will use its best
efforts to provide Lenders with any information received by Agent from Borrower
or any other Loan Party which is required to be provided to a Lender hereunder,
provided that Agent shall not be liable to Lenders for any failure to do so,
except to the extent that such failure is attributable to Agent's gross
negligence or willful misconduct.

                  8.3 Amendments, Consents and Waivers for Certain Actions. In
the event Agent requests the consent of a Lender and does not receive a written
consent or denial thereof within ten (10) Business Days after such Lender's
receipt of such request, then such Lender will be deemed to have given such
consent.


                                      -50-
<PAGE>   55

                  8.4 Set Off and Sharing of Payments. In addition to any rights
now or hereafter granted under applicable law and not by way of limitation of
any such rights, upon the occurrence and during the continuance of any Event of
Default, each Lender is hereby authorized by Borrower at any time or from time
to time, with concurrent or reasonably prompt subsequent notice to Borrower (any
prior notice being hereby expressly waived) to set off and to appropriate and to
apply any and all (A) balances held by such Lender at any of its offices for the
account of Borrower or any of its Subsidiaries (regardless of whether such
balances are then due to Borrower or its Subsidiaries), and (B) other property
at any time held or owing by such Lender to or for the credit or for the account
of Borrower or any of its Subsidiaries, against and on account of any of the
Obligations; except that no Lender shall exercise any such right without the
prior written consent of Agent. Any Lender exercising a right to set off shall,
to the extent the amount of any such set off exceeds its Pro Rata Share of the
amount set off, purchase for cash (and the other Lenders shall sell) interests
in each such other Lender's Pro Rata Share of the Obligations as would be
necessary to cause such Lender to share such excess with each other Lender in
accordance with their respective Pro Rata Shares. Borrower agrees, to the
fullest extent permitted by law, that any Lender may exercise its right to set
off with respect to amounts in excess of its Pro Rata Share of the Obligations
and upon doing so shall deliver such excess to the Agent for the benefit of all
Lenders in accordance with their Pro Rata Shares.

                  8.5 Disbursement of Funds. Agent shall, at all times subject
to the terms and conditions hereof, on behalf of Lenders, disburse funds to
Borrower for Loans requested. Each Lender shall reimburse Agent on demand for
all funds disbursed on its behalf by Agent, or if Agent so requests, each Lender
will remit to Agent its Pro Rata Share of any Loan before Agent disburses same
to Borrower. If Agent elects to require that each Lender make funds available to
Agent, prior to a disbursement by Agent to Borrower, Agent shall advise each
Lender by telephone or telecopy of the amount of such Lender's Pro Rata Share of
the Loan requested by Borrower no later than noon (Atlanta time) on the Funding
Date applicable thereto, and each such Lender shall pay Agent such Lender's Pro
Rata Share of such requested Loan, in same day funds, by wire transfer to
Agent's account on such Funding Date. If any Lender fails to pay the amount of
its Pro Rata Share forthwith upon Agent's demand, Agent shall promptly notify
Borrower, and Borrower shall promptly, but in any event within five (5) Business
Days after receipt of such notice, repay such amount to Agent. Any repayment
required pursuant to this subsection 8.5 shall be without premium or penalty.
Nothing in this subsection 8.5 or elsewhere in this Agreement or the other Loan
Documents, including without limitation the provisions of subsection 8.6, shall
be deemed to require Agent to advance funds on behalf of any Lender or to
relieve any Lender from its obligation to fulfill its commitments hereunder or
to prejudice any rights that Agent or Borrower may have against any Lender as a
result of any default by such Lender hereunder.

                  8.6 Disbursements of Advances; Payment.

                  (A) Settlement.

                  (1) The outstanding principal balance of each of the Revolving
Loans may fluctuate from day to day through Agent's disbursement of funds to,
and receipt of funds from, Borrower. In order to minimize the frequency of
transfers of funds between Agent and each


                                      -51-
<PAGE>   56

Lender, notwithstanding terms to the contrary set forth in Section 1 or Section
8.5, advances and payments of Revolving Loans will be settled among Agent and
Lenders according to the procedures described in this subsection 8.6.
Notwithstanding these procedures, each Lender's obligation to fund its portion
of any Revolving Loans made by Agent to Borrower will commence on the date such
Loans are made by Agent. Such payments will be made by such Lender without
set-off, counterclaim or reduction of any kind.

                  (2)      On the first (1st) Business Day of each week, or more
frequently (including daily), if Agent so elects (each such day being a
"Settlement Date"), Agent will advise each Lender by telephone or telecopy of
the amount of each such Lender's Pro Rata Share of each Revolving Loan balance
as of the close of business of the (2nd) second Business Day immediately
preceding the Settlement Date. In the event that payments are necessary to
adjust the amount of such Lender's required Pro Rata Share of each Loan balance
to such Lender's actual Pro Rata Share of each Revolving Loan balance as of any
Settlement Date, the party from which such payment is due will pay the other, in
same day funds, by wire transfer to the other's account not later than 1:00 p.m.
(Atlanta time) on the Business Day following the Settlement Date.

                  (3)      For purposes of this subsection 8.6(A)(3), the
following terms and conditions will have the meanings indicated:

                  (1)      "Daily Loan Balance" means an amount calculated as of
         the end of each calendar day by subtracting (i) the cumulative
         principal amount paid by Agent to a Lender on each Loan from the
         Closing Date through and including such calendar day, from (ii) the
         cumulative principal amount on each Loan advanced by such Lender to
         Agent on that Loan from the Closing Date through and including such
         calendar day.

                  (2)      "Daily Interest Rate" means an amount calculated by
         dividing the per annum interest rate payable to a Lender on each
         Revolving Loan by three hundred sixty (360).

                  (3)      "Daily Interest Amount" means an amount calculated by
         multiplying the Daily Loan Balance of each Revolving Loan by the
         associated Daily Interest Rate on that Loan.

                  (4)      "Interest Ratio" means a number calculated by
         dividing the total amount of the interest on a Loan received by Agent
         with respect to the immediately preceding month by the total amount of
         interest on that Loan due from Borrower during the immediately
         preceding month.

On the first (1st) Business Day of each month ("Interest Settlement Date"),
Agent will advise each Lender by telephone, telex, or telecopy of the amount of
such Lender's Pro Rata Share of interest and fees on each of the Loans as of the
end of the last day of the immediately preceding month. Provided that such
Lender has made all payments required to be made by it under this Agreement,
Agent will pay to such Lender, by wire transfer to such Lender's account (as
specified by such Lender on the signature page of this Agreement or the
applicable Lender



                                      -52-
<PAGE>   57

Addition Agreement, as amended by such Lender from time to time after the date
hereof pursuant to the notice provisions contained herein or in the applicable
Lender Addition Agreement) not later than 3:00 p.m. (Atlanta time) on the
Interest Settlement Date, such Lender's Pro Rata Share of interest and fees on
each of the Loans. Such Lender's Pro Rata Share of interest on each Loan will be
calculated for that Loan by adding together the Daily Interest Amounts for each
calendar day of the prior month for that Loan and multiplying the total thereof
by the Interest Ratio for that Loan. Such Lender's Pro Rata Share of each of the
fees described in subsection 1.2(B) to which it is entitled shall be paid and
calculated in a manner consistent with the payment and calculation of interest
as described in this subsection 8.6(A).

                  (B)      Related Fee Payments. Payments of all other interest,
fees and expenses not otherwise described in subsection 8.6(A) will be settled
on the first Business Day of each week following receipt of such payment by
Agent in accordance with the provisions of Section 1.

                  (C)      Availability of Lender's Pro Rata Share.

                  (1)      Unless Agent has been notified by a Lender prior to a
Funding Date of such Lender's intention not to fund its Pro Rata Share of the
Loan amount requested by Borrower, Agent may assume that such Lender will make
such amount available to Agent on the Business Day following the next Settlement
Date. If such amount is not, in fact, made available to Agent by such Lender
when due, Agent will be entitled to recover such amount on demand from such
Lender without set-off, counterclaim or deduction of any kind plus interest
thereon, until fully paid, at the Federal Funds Effective Date, and pending such
full payment, such Lender's voting rights hereunder shall be suspended.

                  (2)      Nothing contained in this subsection 8.6(C) will be
deemed to relieve a Lender of its obligation to fulfill its Commitments or to
prejudice any rights Agent or Borrower may have against such Lender as a result
of any default by such Lender under this Agreement.

                  (D)      Return of Payments.

                  (1)      If Agent pays an amount to a Lender under this
Agreement in the belief or expectation that a related payment has been or will
be received by Agent from Borrower and such related payment is not received by
Agent, then Agent will be entitled to recover such amount from such Lender
without set-off, counterclaim or deduction of any kind.

                  (2)      If Agent determines at any time that any amount
received by Agent under this Agreement must be returned to Borrower or paid to
any other person pursuant to any solvency law or otherwise, then,
notwithstanding any other term or condition of this Agreement, Agent will not be
required to distribute any portion thereof to any Lender. In addition, each
Lender will repay to Agent on demand any portion of such amount that Agent has
distributed to such Lender, together with interest at such rate, if any, as
Agent is required to pay to Borrower or such other Person, without set-off,
counterclaim or deduction of any kind.


                                      -53-
<PAGE>   58

                  (E)      The determination of whether Borrower has paid any
amount due hereunder shall not be affected by the provisions of subsections (A)
through (D) of this Section 8.6.

                  8.7      Documentation Agent and Syndication Agent. Agent may,
at any time or from time to time, appoint one or more Lenders as "Documentation
Agent" or "Syndication Agent" hereunder, and such Lender(s) may publicize such
fact. Any such designation shall not confer upon such designee any rights,
privileges, powers, duties, immunities, indemnities or other benefits granted
to, or assumed by, Agent hereunder, but shall be honorary only.


                                   SECTION 9
                                  MISCELLANEOUS

                  9.1      Indemnities. Borrower agrees to indemnify, save, and
hold Agent, each Lender and their respective officers, directors, employees,
agents, and attorneys (the "Indemnitees") harmless from and against any and all
liabilities, obligations, losses, damages, penalties, actions, judgments, suits
and claims of any kind or nature whatsoever that may be imposed on, incurred by,
or asserted against the Indemnitee in any action, claim, suit, proceeding or
investigation (whether or not the Indemnitee is a party thereto) as a result of
its being a party to this Agreement or any other Loan Document, or its exercise
of any rights or remedies hereunder, thereunder or under applicable law,
including, without limitation, by reason of any defense, setoff, claim,
counterclaim, recoupment or reduction of liability asserted by any Person
obligated to Borrower or any Affiliate Guarantor (or to whom Borrower or any
Affiliate Guarantor is otherwise obligated) in respect of any Collateral;
provided that Borrower shall have no obligation to an Indemnitee hereunder with
respect to liabilities arising from either (i) the gross negligence or willful
misconduct of that Indemnitee or (ii) the breach by any Indemnitee of any term
of this Agreement or any Loan Document binding on it. This subsection and other
indemnification provisions contained within the Loan Documents shall survive the
termination of this Agreement.

                  9.2      Amendments and Waivers. Except as otherwise provided
herein, no amendment, modification, termination or waiver of any provision of
this Agreement, the Notes or any of the other Loan Documents, or consent to any
departure by any Loan Party therefrom, shall in any event be effective unless
the same shall be in writing and signed by Requisite Lenders (or Agent, if
expressly set forth herein, in any Note or in any other Loan Document) and the
applicable Loan Party; provided, that except to the extent permitted by the
applicable Lender Addition Agreement, no amendment, modification, termination or
waiver shall, unless in writing and signed by all Lenders, do any of the
following: (a) increase any Lender's Commitment; (b) reduce the principal of,
rate of interest on or fees payable with respect to any Loan; (c) extend the
Expiry Date, or change any date fixed for any payment of principal, interest or
fees; (d) change the aggregate unpaid principal amount of the Loans; (e) change
the percentage of Lenders which shall be required for Lenders or any of them to
take any action hereunder; (f) release Collateral (except if the sale or
disposition of such Collateral is permitted under subsection 8.2 or any other
Loan Document); (g) amend or waive this Section 9.2 or any of the definitions of
the terms used in this Section 9.2 insofar as the definitions affect the
substance of


                                      -54-
<PAGE>   59

this Section 9.2; (h) change the requirement that all Lenders must consent to
any proposed Acquisition before it can be an Approved Acquisition; or (i) change
the form or manner in which interest is required to be paid; and provided,
further, that no amendment, modification, termination or waiver affecting the
rights or duties of Agent under any Loan Document shall in any event be
effective, unless in writing and signed by Agent, in addition to Lenders
required hereinabove to take such action. Each amendment, modification,
termination or waiver shall be effective only in the specific instance and for
the specific purpose for which it was given. No amendment, modification,
termination or waiver shall be required for Agent to take additional Collateral
for the ratable benefit of the Lenders pursuant to any Loan Document. No
amendment, modification, termination or waiver of any provision of any Note
shall be effective without the written concurrence of the holder of that Note.
No notice to or demand on Borrower or any other Loan Party in any case shall
entitle Borrower or any other Loan Party to any other or further notice or
demand in similar or other circumstances unless and except to the extent (if
any) such notice or demand otherwise is required pursuant hereto or pursuant to
any other Loan Document. Any amendment, modification, termination, waiver or
consent effected in accordance with this Section 9.2 shall be binding upon each
holder of the Notes at the time outstanding, each future holder of the Notes,

                                    or in the applicable Lender Addition
                                    Agreement

                  9.4      Failure or Indulgence Not Waiver; Remedies
Cumulative. No failure or delay on the part of Agent or any Lender to exercise,
nor any partial exercise of, any power, right or privilege hereunder or under
any other Loan Documents shall impair such power, right, or privilege or be
construed to be a waiver of any Default or Event of Default. All rights and
remedies existing hereunder or under any other Loan Document are cumulative to
and not exclusive of any rights or remedies otherwise available.

                  9.5      Marshalling; Payments Set Aside. Neither Agent nor
any Lender shall be under any obligation to marshall any assets in payment of
any or all of the Obligations. To the extent that Borrower makes payment(s) or
Agent enforces its Liens or Agent or any Lender exercises its right of set-off,
and such payment(s) or the proceeds of such enforcement or set-off are
subsequently invalidated, declared to be fraudulent or preferential, set aside,
or required to be repaid by anyone, then to the extent of such recovery, the
Obligations or part thereof originally intended to be satisfied, and all Liens,
rights and remedies therefor, shall be revived and continued in full force and
effect as if such payment had not been made or such enforcement or set-off had
not occurred.

                  9.6      Severability. The invalidity, illegality, or
unenforceability in any jurisdiction of any provision under the Loan Documents
shall not affect or impair the remaining provisions in the Loan Documents.

                  9.7      Lenders' Obligations Several; Independent Nature of
Lenders' Rights. The obligation of each Lender hereunder is several and not
joint and no Lender shall be responsible for the obligation or commitment of any
other Lender hereunder. In the event that any Lender at any time should fail to
make a Loan as herein provided, the Lenders, or any of them, at their sole
option, may make the Loan that was to have been made by the Lender so failing to
make such Loan. Nothing contained in any Loan Document and no action taken by
Agent or any Lender pursuant hereto or thereto shall be deemed to constitute
Lenders to be a


                                      -56-
<PAGE>   61

partnership, an association, a joint venture or any other kind of entity. The
amounts payable at any time hereunder to each Lender shall be a separate and
independent debt.

                  9.8      Headings. Section and subsection headings are
included herein for convenience of reference only and shall not constitute a
part of this Agreement for any other purposes or be given substantive effect.

                  9.9      Applicable Law. THIS AGREEMENT AND, UNLESS EXPRESSLY
PROVIDED THEREIN, THE OTHER LOAN DOCUMENTS, SHALL BE GOVERNED BY AND SHALL BE
CONSTRUED AND ENFORCED IN ACCORDANCE WITH THE INTERNAL LAWS OF THE STATE OF
GEORGIA.

                  9.10     Successors and Assigns. This Agreement shall be
binding upon and inure to the benefit of the parties hereto and their respective
successors and permitted assigns. Borrower may not assign its rights or
obligations hereunder without the written consent of all Lenders.

                  9.11     No Fiduciary Relationship. No provision in the Loan
Documents and no course of dealing between the parties shall be deemed to create
any fiduciary duty owing to Borrower by Agent or any Lender.

                  9.12     Construction. Agent, each Lender and Borrower
acknowledge that each of them has had the benefit of legal counsel of its own
choice and has been afforded an opportunity to review the Loan Documents with
its legal counsel and that the Loan Documents shall be construed as if jointly
drafted by Agent, each Lender and Borrower.

                  9.13     Confidentiality. Each party hereto agrees to exercise
its best efforts to keep any non-public information contained in or delivered
pursuant to the Loan Documents confidential from Persons other than those
employed by or engaged by such party and, in the case of Lenders, and those
employed by or engaged by each such Lender's assignees or participants, or
potential assignees or participants who, in each instance, need to know such
information to evaluate or administer the Loan Documents. This subsection shall
not apply to disclosures required to be made by any party to any regulatory or
governmental agency or pursuant to legal process.

                  9.14     Consent to Jurisdiction and Service of Process.

                  (1)      EACH PARTY HERETO HEREBY IRREVOCABLY SUBMITS TO THE
NON-EXCLUSIVE JURISDICTION OF ANY UNITED STATES FEDERAL OR STATE COURT SITTING

EFFECTIVE AND BINDING SERVICE IN EVERY RESPECT. A COPY OF ANY SUCH PROCESS SO
SERVED SHALL BE MAILED BY REGISTERED MAIL TO EACH PARTY AT ITS ADDRESS PROVIDED
IN SUBSECTION 9.3 EXCEPT THAT UNLESS OTHERWISE PROVIDED BY APPLICABLE LAW, ANY
FAILURE TO MAIL SUCH COPY SHALL NOT AFFECT THE VALIDITY OF SERVICE OF PROCESS.
IF ANY AGENT APPOINTED BY A PARTY REFUSES TO ACCEPT SERVICE, SUCH PARTY HEREBY
AGREES THAT SERVICE UPON IT BY MAIL SHALL CONSTITUTE SUFFICIENT NOTICE. NOTHING
HEREIN SHALL AFFECT THE RIGHT TO SERVE PROCESS IN ANY OTHER MANNER PERMITTED BY
LAW.

                  9.15     Waiver of Jury Trial. EACH PARTY HERETO HEREBY WAIVES
ITS RIGHTS TO A JURY TRIAL OF ANY CLAIM OR CAUSE OF ACTION BASED UPON OR ARISING
OUT OF THIS AGREEMENT, ANY OF THE OTHER LOAN DOCUMENTS, OR ANY DEALINGS RELATING
TO THE SUBJECT MATTER OF THIS LOAN TRANSACTION AND THE LENDER/BORROWER
RELATIONSHIP THAT IS BEING ESTABLISHED. THE SCOPE OF THIS WAIVER IS INTENDED TO
BE ALL-ENCOMPASSING OF ANY AND ALL DISPUTES THAT MAY BE FILED IN ANY COURT AND
THAT RELATE TO THE SUBJECT MATTER OF THIS TRANSACTION, INCLUDING WITHOUT
LIMITATION, CONTRACT CLAIMS, TORT CLAIMS, BREACH OF DUTY CLAIMS, AND ALL OTHER
COMMON LAW AND STATUTORY CLAIMS. EACH PARTY ACKNOWLEDGES THAT THIS WAIVER IS A
MATERIAL INDUCEMENT TO ENTER INTO A BUSINESS RELATIONSHIP, THAT EACH HAS ALREADY
RELIED ON THE WAIVER IN ENTERING INTO THIS AGREEMENT AND THAT EACH WILL CONTINUE
TO RELY ON THE WAIVER IN ITS RELATED FUTURE DEALINGS. EACH PARTY FURTHER
WARRANTS AND REPRESENTS THAT EACH HAS REVIEWED THIS WAIVER WITH ITS LEGAL
COUNSEL, AND THAT EACH KNOWINGLY AND VOLUNTARILY WAIVES ITS JURY TRIAL RIGHTS

THE LOAN DOCUMENTS, OR TO ANY OTHER DOCUMENTS OR AGREEMENTS RELATING TO THE
LOANS OR THE LENDER LETTERS OF CREDIT OR RISK PARTICIPATION AGREEMENTS. IN THE
EVENT OF LITIGATION, THIS AGREEMENT MAY BE FILED AS A WRITTEN CONSENT TO A TRIAL
BY THE COURT. EACH PARTY HERETO ALSO WAIVES ANY BOND OR SURETY OR SECURITY UPON
SUCH BOND WHICH MIGHT, BUT FOR THIS WAIVER, BE REQUIRED OF ANY OTHER PARTY

Existing Credit Agreement and, to the extent amended and restated pursuant to
the Loan Documents being executed concurrently herewith, any other "Loan
Documents" (as that term is defined therein), and may not be contradicted or

discussions of the parties hereto.

                  9.18     Counterparts; Effectiveness. This Agreement and any

This Agreement shall become effective upon the execution of a counterpart hereof
by each of the parties hereto.

                  9.19     Press Release; Public Offering Materials. Borrower

fees, costs and expenses for which Borrower is responsible under this subsection
shall be deemed part of the Obligations when incurred, payable in accordance

         the rate table set forth below; and (ii) beginning with the Adjustment

         That is to say, the Applicable Margin shall be subject to reduction or
         increase, as applicable and as set forth in the table above, on a
         quarterly basis according to the performance of Borrower as measured by
         the Total Debt Coverage for the Test Period ending September 30, 2000.
         Any such increase or reduction in the Applicable Margin provided for
         herein shall be effective on the first day of the next month following
         receipt by Agent of the applicable financial statements and
         corresponding Compliance Certificate. If the financial statements and
         the Compliance Certificate of Borrower setting forth Total Debt
         Coverage are not received by Agent by the date required pursuant to
         Section 4.1 of this Agreement, the Applicable Margin shall be
         determined at Level III of the rate table set forth above, commencing
         on the date when any cure period in respect of Borrower's failure to
         deliver such financial statements and Compliance Certificate shall have
         expired and continuing until such time as such financial statements and
