         (B) INTEREST PERIODS. In connection with each Eurodollar Rate Loan,
the applicable Borrower may, pursuant to the applicable Notice of
Conversion/Continuation select an interest period (each an "INTEREST PERIOD")
to be applicable to such Loan, which Interest Period shall be, at the
applicable Borrower's option, either a one-, two- or three-month period;
provided that:

                  (i)      the initial Interest Period for any Eurodollar Rate
         Loan shall commence on the Funding Date in respect of such Loan, in
         the case of a Loan initially made as a Eurodollar Rate Loan, or on
         the date specified in the applicable Notice of
         Conversion/Continuation, in the case of a Loan converted to a
         Eurodollar Rate Loan;

                  (ii)     in the case of immediately successive Interest
         Periods applicable to a Eurodollar Rate Loan continued as such
         pursuant to a Notice of Conversion/Continuation, each successive
         Interest Period shall commence on the day on which the next preceding
         Interest Period expires;

                  (iii)    if an Interest Period would otherwise expire on a
         day that is not a Business Day, such Interest Period shall expire on
         the next succeeding Business Day; provided that, if any Interest
         Period would otherwise expire on a day that is not a Business Day but
         is a day of the month after which no further Business Day occurs in
         such month, such Interest Period shall expire on the next preceding
         Business Day;

                  (iv)     any Interest Period that begins on the last
         Business Day of a calendar month (or on a day for which there is no
         numerically corresponding day in the calendar month at the end of
         such Interest Period) shall, subject to clauses (v), (vi) and (vii)
         of this subsection 2.2B, end on the last Business Day of a calendar
         month;

                  (v)      no Interest Period with respect to any portion of
         the Loans shall extend beyond the Maturity Date for such Loans;

                  (vi)     no Interest Period with respect to any portion of
         the Series A Revolving Loans shall extend beyond a date on which
         Finance Sub is required to make a scheduled payment of principal on
         the Series A Revolving Loans unless the sum of (a) the aggregate
         principal amount of Series A Revolving Loans that are Base Rate Loans
         plus (b) the aggregate principal amount of Series A Revolving Loans
         that are Eurodollar Rate Loans with Interest Periods expiring on or
         before such date equals or exceeds the principal amount required to
         be paid on the Series A Revolving Loans on such date.

                  (vii)    no Interest Period with respect to any portion of
         the Series B Term Loans or Series C Term Loans shall extend beyond a
         date on which Company is required to make a scheduled payment of
         principal of the Series B Term Loans or Series C Term loans, as the
         case may be, unless the sum of (a) the aggregate principal amount of
         Series

                                      35

<PAGE>   44

         B Term Loans or Series C Term Loans, as the case may be, that are
         Base Rate Loans plus (b) the aggregate principal amount of Series B
         Term Loans or Series C Term Loans, as the case may be, that are
         Eurodollar Rate Loans with Interest Periods expiring on or before
         such date equals or exceeds the principal amount required to be paid
         on the Series B Term Loans or Series C Term Loans, as the case may
         be, on such date;

                  (viii)   [Intentionally Omitted]

                  (ix)     there shall be no more than ten (10) Interest
         Periods outstanding at any time; and

                  (x)      in the event a Borrower fails to specify an
         Interest Period for any Eurodollar Rate Loan in the applicable Notice
         of Conversion/Continuation, such shall be deemed to have selected an
         Interest Period of one month.

         Any Loan made prior to the Restatement Closing Date shall continue
with the Interest Period it had under the Original Credit Agreement subject to
the provisions of subsection 2.2D below.

         (C) INTEREST PAYMENTS. Subject to the provisions of subsection 2.2E,
interest on each Loan shall be payable in arrears on and to each Interest
Payment Date applicable to that Loan, upon any prepayment of that Loan (to the
extent accrued on the amount being prepaid) and at maturity (including final
maturity).

         (D) CONVERSION OR CONTINUATION. Subject to the provisions of
subsection 2.6, each Borrower shall have the option (i) to convert at any time
all or any part of its outstanding Loans equal to $5,000,000 and integral
multiples of $1,000,000 in excess of that amount from Loans bearing interest
at a rate determined by reference to one basis to Loans bearing interest at a
rate determined by reference to an alternative basis or (ii) upon the
expiration of any Interest Period applicable to a Eurodollar Rate Loan, to
continue all or any portion of such Loan equal to $5,000,000 and integral
multiples of $1,000,000 in excess of that amount as a Eurodollar Rate Loan;
provided, however, that a Eurodollar Rate Loan may only be converted into a
Base Rate Loan on the expiration date of an Interest Period applicable
thereto.

         The applicable Borrower shall deliver a Notice of
Conversion/Continuation to Administrative Agent no later than 10:00 A.M. (New
York City time) at least one Business Day in advance of the proposed
conversion date (in the case of a conversion to a Base Rate Loan) and at least
three Business Days in advance of the proposed conversion/continuation date
(in the case of a conversion to, or a continuation of, a Eurodollar Rate
Loan). A Notice of Conversion/Continuation shall specify (i) the proposed
conversion/continuation date (which shall be a Business Day), (ii) the amount
and type of the Loan to be converted/continued, (iii) the nature of the
proposed conversion/continuation, (iv) in the case of a conversion to, or a
continuation of, a Eurodollar Rate Loan, the requested Interest Period, and
(v) in the case of a conversion to, or a continuation of, a Eurodollar Rate
Loan, that no Potential Event of Default or Event of Default has occurred and
is continuing. In lieu of delivering the above-described Notice of
Conversion/Continuation, such Borrower may give Administrative Agent
telephonic notice by the required time of any proposed conversion/continuation
under this subsection 2.2D;

                                      36

<PAGE>   45


provided that such notice shall be promptly confirmed in writing by delivery
of a Notice of Conversion/Continuation to Administrative Agent on or before
the proposed conversion/continuation date. Upon receipt of written or
telephonic notice of any proposed conversion/continuation under this
subsection 2.2D, Administrative Agent shall promptly transmit such notice by
telefacsimile or telephone to each Lender.

         Neither Administrative Agent nor any Lender shall incur any liability
to either Borrower in acting upon any telephonic notice referred to above that
Administrative Agent believes in good faith to have been given by a duly
authorized officer or other person authorized to act on behalf of such
Borrower or for otherwise acting in good faith under this subsection 2.2D, and
upon conversion or continuation of the applicable basis for determining the
interest rate with respect to any Loans in accordance with this Agreement
pursuant to any such telephonic notice the applicable Borrower shall have
effected a conversion or continuation, as the case may be, hereunder.

         Except as otherwise provided in subsections 2.6B, 2.6C and 2.6G, a
Notice of Conversion/Continuation for conversion to, or continuation of, a
Eurodollar Rate Loan (or telephonic notice in lieu thereof) shall be
irrevocable on and after the related Interest Rate Determination Date, and the
applicable Borrower shall be bound to effect a conversion or continuation in
accordance therewith.

         (E) DEFAULT INTEREST. Any principal payments on the Loans not paid
when due and, to the extent permitted by applicable law, any interest payments
on the Loans or any fees or other amounts owed hereunder not paid when due, in
each case whether at stated maturity, by notice of prepayment, by acceleration
or otherwise, shall thereafter bear interest (including post-petition interest
in any proceeding under the Bankruptcy Code or other applicable bankruptcy
laws) payable on demand at a rate which is 2% per annum in excess of the
interest rate otherwise payable under this Agreement with respect to the
applicable Loans (or, in the case of any such fees and other amounts, at a
rate which is 2% per annum in excess of the interest rate otherwise payable
under this Agreement for Base Rate Loans); provided that, in the case of
Eurodollar Rate Loans, upon the expiration of the Interest Period in effect at
the time any such increase in interest rate is effective such Eurodollar Rate
Loans shall thereupon become Base Rate Loans and shall thereafter bear
interest payable upon demand at a rate which is 2% per annum in excess of the
interest rate otherwise payable under this Agreement for Base Rate Loans.
Payment or acceptance of the increased rates of interest provided for in this
subsection 2.2E is not a permitted alternative to timely payment and shall not
constitute a waiver of any Event of Default or otherwise prejudice or limit
any rights or remedies of Administrative Agent or any Lender.

         (F) COMPUTATION OF INTEREST. Interest on the Loans shall be computed
(i) in the case of Base Rate Loans, on the basis of a 365-day or 366-day year,
as the case may be, and (ii) in the case of Eurodollar Rate Loans, on the
basis of a 360-day year, in each case for the actual number of days elapsed in
the period during which it accrues. In computing interest on any Loan, the
date of the making of such Loan or the first day of an Interest Period
applicable to such Loan or, with respect to a Base Rate Loan being converted
from a Eurodollar Rate Loan, the date of conversion of such Eurodollar Rate
Loan to such Base Rate Loan, as the case may be, shall be included, and the
date of payment of such Loan or the expiration date of an Interest Period
applicable to such Loan or, with respect to a Base Rate Loan being converted
to a Eurodollar

                                      37

<PAGE>   46

Rate Loan, the date of conversion of such Base Rate Loan to such Eurodollar
Rate Loan, as the case may be, shall be excluded; provided that if a Loan is
repaid on the same day on which it is made, one day's interest shall be paid
on that Loan.

2.3      FEES.

         (A) [INTENTIONALLY OMITTED]

         (B) OTHER FEES. Borrowers agree to pay to Arranger and Administrative
Agent such other fees in the amounts and at the times separately agreed upon
between Company, Arranger and Administrative Agent.

         (C) RESTRUCTURING FEE. Borrowers shall pay to Administrative Agent,
for distribution to Lenders executing this Agreement in accordance with their
Pro Rata Shares, a restructuring fee equal to 1.25% of the aggregate
outstanding principal amount of Loans (after giving effect to the prepayments
referred to in subsection 3.1J), 1.00% payable in Cash upon the Restatement
Effective Date and the remaining 0.25% payable from Net Asset Sale Proceeds
received following the Restatement Effective Date (such 0.25%, the "DEFERRED
RESTRUCTURING FEE").

         on the date required and, if given by telephone, promptly confirmed
         in writing to Administrative Agent (which original written or
         telephonic notice Administrative Agent will promptly transmit by
         telefacsimile or telephone to each Lender), at any time and from time
         to time prepay any Loans on any Business Day in whole or in part in

         respect to any Eurodollar Rate Loan prepaid prior to the expiration
         of the Interest Period applicable thereto, Borrowers shall pay all
         amounts payable pursuant to subsection 2.6D.  Notice of prepayment
         having been given as aforesaid, the principal amount of the Loans
         specified in such notice shall become due and payable on the
         prepayment date specified therein.  Any such voluntary prepayment
         shall be applied as specified in subsection 2.4B(iv).

                  (ii)     [Intentionally omitted].

                  (iii)    Mandatory Prepayments. The Loans shall be prepaid
         in the amounts and under the circumstances set forth below, all such
         prepayments to be applied as set forth below or as more specifically
         provided in subsection 2.4B(iv):

                           (a)      Prepayments From Net Asset Sale Proceeds.
                  No later than the first Business Day following the date of
                  receipt by Company or any of its Restricted Subsidiaries of
                  any Net Asset Sale Proceeds in respect of any Asset Sale
                  (excluding ACSI Network Sales only to the extent the Net
                  Asset Sale Proceeds received from such Asset Sales are
                  accounted for as revenue (whether currently or on a deferred
                  basis) from continuing operations in accordance with GAAP),
                  Company or Finance Sub, as applicable, shall apply such Net
                  Asset Sale Proceeds first to pay the Deferred Restructuring
                  Fee to the full extent thereof, and second to prepay the
                  Loans.  Notwithstanding the foregoing, as long as no Event
                  of Default or Potential Event of Default shall have occurred
                  and be continuing and the Deferred Restructuring Fee has
                  been paid in full, Company or Finance Sub, as applicable,
                  may reinvest within 270 days from the date of receipt
                  thereof up to 50% of the Net Asset Sale Proceeds in
                  Telecommunications Assets used by Company and its Restricted
                  Subsidiaries in the conduct of its business and to the
                  extent of the amount of Net Asset Sale Proceeds so
                  reinvested (up to such 50% limit) no prepayment of Loans
                  shall be required under this subsection 2.4(B)(iii)(a).  If
                  upon any Asset Sale, Company elects to reinvest up to 50% of
                  the Net Asset Sale Proceeds as permitted under this
                  subsection 2.4B(iii)(a), (1) no later than the first
                  Business Day following the consummation of such Asset Sale,

<PAGE>   49

                  Company shall deliver an Officers' Certificate to
                  Administrative Agent demonstrating the derivation of the Net
                  Asset Sale Proceeds of such Asset Sale from the gross sales
                  prices thereof and certifying the portion of such proceeds
                  which Company elects to reinvest in Telecommunications
                  Assets and certifying that no Event of Default or Potential
                  Event of Default shall have occurred and be continuing and
                  (2) upon the expiration of 270 days after the date of
                  receipt of the Net Asset Sale Proceeds certified as being
                  scheduled for reinvestment, Company shall deliver to
                  Administrative Agent an Officers' Certificate indicating the
                  amount of Net Asset Sale Proceeds reinvested as of such
                  date, the assets in which such Net Asset Sale Proceeds have
                  been reinvested, and the amount of any remaining Net Asset
                  Sale Proceeds which shall be applied to prepay the Loans as
                  set forth in this subsection 2.4B(iii)(a).

                           (b)      Prepayments from Net
                  Insurance/Condemnation Proceeds. No later than the second
                  Business Day following the date of receipt by Administrative
                  Agent or by Company or any of its Subsidiaries of any Net
                  Insurance/Condemnation Proceeds that are required to be
                  applied to prepay the Loans pursuant to the provisions of
                  subsection 5.4C, Company or Finance Sub, as applicable,
                  shall prepay the Loans in an aggregate amount equal to the
                  amount of such Net Insurance/Condemnation Proceeds.

                           (c)      Prepayments from Consolidated Excess Cash
                  Flow. In the event that there shall be Consolidated Excess
                  Cash Flow for any Fiscal Year (commencing with Fiscal Year
                  2002), Company or Finance Sub, as applicable, shall, no
                  later than 100 days after the end of such Fiscal Year,
                  prepay the Loans in an aggregate amount equal to 75% of such
                  Consolidated Excess Cash Flow.

                           (d)      Prepayments Due to Restrictions on Loans.
                  Company shall from time to time prepay the Series B Term
                  Loans and Series C Term Loans to the extent necessary to
                  give effect to the limitations set forth in subsection
                  2.1A(iv).

                           (e)      Prepayments Due to Payments of Master
                  Note. Company shall, from time to time, prepay the Series B
                  Term Loans and the Series C Term Loans to the extent
                  necessary so that the aggregate outstanding amount of Series
                  B Term Loans and the Series C Term Loans shall not at any
                  time exceed the aggregate amount outstanding under the
                  Master Note.

                           (f)      Calculations of Net Proceeds Amounts,
                  Additional Prepayments and Reductions Based on Subsequent
                  Calculations.  Concurrently with any prepayment of the Loans
                  pursuant to subsections 2.4B(iii)(a)-(c), Company shall
                  deliver to Administrative Agent an Officers' Certificate
                  demonstrating the calculation of the amount (the "NET
                  PROCEEDS AMOUNT") of the applicable Net Asset Sale Proceeds
                  or Net Insurance/Condemnation Proceeds (as such terms are
                  defined in subsections 2.4B(iii)(a) and (b) respectively) or
                  the applicable Consolidated Excess Cash Flow, as the case
                  may be, that gave rise to such prepayment and/or reduction.
                  In the event that Company shall subsequently determine that
                  the actual Net Proceeds Amount was greater than the amount
                  set

                                      41

<PAGE>   50

                  forth in such Officers' Certificate, Company or Finance Sub,
                  as applicable, shall promptly make an additional prepayment
                  of the Loans in an amount equal to the amount of such
                  excess, and Company shall concurrently therewith deliver to
                  Administrative Agent an Officers' Certificate demonstrating
                  the derivation of the additional Net Proceeds Amount
                  resulting in such excess.

                  (iv)     Application of Prepayments.

                           (a)      Application of Prepayments by Type of
                  Loans.  Any amount (the "APPLIED AMOUNT") to be applied as a
                  voluntary prepayment pursuant to subsection 2.4B(i) or
                  mandatory prepayment pursuant to subsections
                  2.4B(iii)(a)-(c) shall be applied to reduce the aggregate
                  amount of Loans of Lenders in accordance with their Pro Rata
                  Shares (as determined pursuant to clause (iv) of the
                  definition thereof).  With respect to each Lender's
                  outstanding Loans, prepayments shall be applied first, to
                  reduce such Lender's outstanding Series B Term Loans,
                  second, to reduce such Lender's Series C Term Loans and
                  third, to reduce such Lender's Series A Revolving Loans
                  (provided that the Lenders may agree among themselves to
                  reallocate prepayments otherwise payable to the Series A
                  Revolving Loans).  Voluntary prepayments pursuant to
                  subsection 2.4B(i) shall be applied to reduce scheduled
                  installments of principal of the Series A Revolving Loans,
                  Series B Term Loans and Series C Term Loans on a pro rata
                  basis.  Mandatory prepayments pursuant to subsection
                  2.4B(iii)(a)-(c) shall be applied to reduce scheduled
                  installments of principal of the Series A Revolving Loans,
                  Series B Term Loans and Series C Term Loans in inverse order
                  of maturity.

                           (b)      Application of Prepayments to Base Rate
                  Loans and Eurodollar Rate Loans. Any prepayment of Loans
                  shall be applied first to Base Rate Loans to the full extent
                  thereof before application to Eurodollar Rate Loans, in each
                  case in a manner which minimizes the amount of any payments
                  required to be made pursuant to subsection 2.6D.

                  (v)      Prepayment Fees.  If any portion of the Series C
         Term Loans is prepaid on or prior to the second anniversary of the
         Closing Date, Company shall pay to Administrative Agent, for
         distribution to Lenders having Series C Term Loans so prepaid in
         accordance with their Pro Rata Shares, a fee equal to (1) 3.00% of
         the principal amount of Series C Term Loans so prepaid during the
         period commencing on the Closing Date and ending on the day prior to
         the first anniversary of the Closing Date and (2) 2.00% of the
         principal amount of Series C Term Loans so prepaid during the period
         commencing on the first anniversary of the Closing Date and ending on
         the second anniversary of the Closing Date; provided, however, that
         such prepayment fees shall not be payable with respect to (a) the
         prepayments made in accordance with subsections 3.1J and 3.1O, (b)
         mandatory prepayments made pursuant to subsection 2.4B(iii)(a)-(c) or
         (c) voluntary prepayments pursuant to subsection 2.4B(i) made within
         90 days after the Restatement Effective Date.

         (C) GENERAL PROVISIONS REGARDING PAYMENTS.

                  (i)      Manner and Time of Payment. All payments by each
         Borrower of principal, interest, fees and other Obligations hereunder
         and under the Notes shall be made in Dollars in same day funds,
         without defense, setoff or counterclaim, free of any restriction or
         condition, and delivered to Administrative Agent not later than 12:00
         Noon (New York City time) on the date due at the Funding and Payment
         Office for the account of Lenders; funds received by Administrative
         Agent after that time on such due date shall be deemed to have been
         paid by such Borrower on the next succeeding Business Day.

                  (ii)     Application of Payments to Principal and Interest.
         All payments in respect of the principal amount of any Loan shall
         include payment of accrued interest on the principal amount being
         repaid or prepaid, and all such payments shall be applied to the
         payment of interest before application to principal.

                  (iii)    Apportionment of Payments.  Aggregate principal and
         interest payments in respect of Loans shall be apportioned among all
         outstanding Loans to which such payments relate, in each case
         proportionately to Lenders' respective Pro Rata Shares, subject to
         the provisions of subsection 2.4B(iv)(a). Administrative Agent shall
         promptly distribute to each Lender, at its primary address set forth
         below its name on the appropriate signature page hereof or at such
         other address as such Lender may request, its Pro Rata Share of all
         such payments received by Administrative Agent and the commitment
         fees of such Lender when received by Administrative Agent pursuant to
         subsection 2.3.  Notwithstanding the foregoing provisions of this
         subsection 2.4C(iii), if, pursuant to the provisions of subsection
         2.6C, any Notice of Conversion/Continuation is withdrawn as to any
         Affected Lender or if any Affected Lender makes Base Rate Loans in
         lieu of its Pro Rata Share of any Eurodollar Rate Loans,
         Administrative Agent shall give effect thereto in apportioning
         payments received thereafter.

                  (iv)     Payments on Business Days. Whenever any payment to
         be made hereunder shall be stated to be due on a day that is not a
         Business Day, such payment shall be made on the next succeeding
         Business Day and such extension of time shall be included in the
         computation of the payment of interest hereunder or of the commitment
         fees hereunder, as the case may be.

                  (v)      Notation of Payment. Each Lender agrees that before
         disposing of any Note held by it, or any part thereof (other than by
         granting participations therein), that Lender will make a notation
         thereon of all Loans evidenced by that Note and all principal
         payments previously made thereon and of the date to which interest
         thereon has been paid; provided that the failure to make (or any
         error in the making of) a notation of any Loan made under such Note
         shall not limit or otherwise affect the obligations of Borrowers
         hereunder or under such Note with respect to any Loan or any payments
         of principal or interest on such Note.

         (D) APPLICATION OF PROCEEDS OF COLLATERAL AND PAYMENTS UNDER
SUBSIDIARY GUARANTY.

                  (i)      Application of Proceeds of Collateral. Except as
         provided in subsection 2.4B(iii)(a) with respect to prepayments from
         Net Asset Sale Proceeds, all proceeds received by Administrative
         Agent in respect of any sale of, collection from, or other
         realization upon all or any part of the Collateral under any
         Collateral Document may, in the discretion of Administrative Agent,
         be held by Administrative Agent as Collateral for, and/or (then or at
         any time thereafter) applied in full or in part by Administrative
         Agent against, the applicable Secured Obligations (as defined in such
         Collateral Document) in the following order of priority:

                           (a)      To the payment of all costs and expenses
                  of such sale, collection or other realization, including
                  reasonable compensation to Administrative Agent and its
                  agents and counsel, and all other expenses, liabilities and
                  advances made or incurred by Administrative Agent in
                  connection therewith, and all amounts for which
                  Administrative Agent is entitled to indemnification under
                  such Collateral Document and all advances made by
                  Administrative Agent thereunder for the account of the
                  applicable Loan Party, and to the payment of all costs and
                  expenses paid or incurred by Administrative Agent in
                  connection with the exercise of any right or remedy under
                  such Collateral Document, all in accordance with the terms
                  of this Agreement and such Collateral Document;

                           (b)      thereafter, to the extent of any excess
                  such proceeds, to the payment of all other such Secured
                  Obligations for the ratable benefit of the holders thereof;
                  and

                           (c)      thereafter, to the extent of any excess
                  such proceeds, to the payment to or upon the order of such
                  Loan Party or to whosoever may be lawfully entitled to
                  receive the same or as a court of competent jurisdiction may
                  direct.

                  (ii)     Application of Payments Under Subsidiary Guaranty.
         All payments received by Administrative Agent under the Subsidiary
         Guaranty shall be applied promptly from time to time by
         Administrative Agent in the following order of priority:

                           (a)      To the payment of the costs and expenses
                  of any collection or other realization under the Subsidiary
                  Guaranty, including reasonable compensation to
                  Administrative Agent and its agents and counsel, and all
                  expenses, liabilities and advances made or incurred by
                  Administrative Agent in connection therewith, all in
                  accordance with the terms of this Agreement and the
                  Subsidiary Guaranty;

                           (b)      thereafter, to the extent of any excess
                  such payments, to the payment of all other Guarantied
                  Obligations (as defined in the Subsidiary Guaranty) for the
                  ratable benefit of the holders thereof; and

                           (c)      thereafter, to the extent of any excess
                  such payments, to the payment to the applicable Subsidiary
                  Guarantor or to whosoever may be lawfully entitled to
                  receive the same or as a court of competent jurisdiction may
                  direct.

                                      44

<PAGE>   53

                  (iii)    Ratable Sharing of Proceeds of Collateral and
         Subsidiary Guaranty.  Any and all amounts received by Administrative
         Agent in connection with the enforcement of any of the Collateral
         Documents or the Subsidiary Guaranty or in connection with a
         distribution in a bankruptcy, insolvency or similar proceeding to be
         applied against any of the Obligations hereunder shall be shared
         ratably by all Lenders hereunder in accordance with their Pro Rata
         Shares (as determined pursuant to clause (iv) of the definition
         thereof), irrespective of whether the Obligations of all Lenders or
         only the Obligations of Lenders having outstanding Series A Revolving
         Loans, Series B Term Loans or Series C Term Loans are secured by the
         Collateral with respect to which such amounts are received or
         guaranteed by the Subsidiary Guaranty.

2.5      USE OF PROCEEDS.

         (A) SERIES A REVOLVING LOANS. The proceeds of the Series A Revolving
Loans were applied by Finance Sub for working capital and for other general
corporate purposes, including the financing of capital expenditures from time
to time.

         (B) SERIES B TERM LOANS AND SERIES C TERM LOANS. The proceeds of the
Series B Term Loans and Series C Term Loans were applied by Company solely to
finance the acquisition, construction or improvement of Telecommunications
Assets of Company and its Restricted Subsidiaries; provided that Company used
all proceeds of any Series B Term Loans and Series C Term Loans to make
intercompany loans to Finance Sub pursuant to the Master Note which were
secured by the Finance Sub Pledge and Security Agreement, and Finance Sub in
turn made intercompany loans of such proceeds to the applicable Restricted
Subsidiary of Finance Sub pursuant to the Intercompany Purchase Money Note
which were secured by the Intercompany Pledge and Security Agreement.

         (C) MARGIN REGULATIONS. No portion of the proceeds of any borrowing
under this Agreement was used by Company or any of its Subsidiaries in any
manner that might cause the borrowing or the application of such proceeds to
violate Regulation U, Regulation T or Regulation X of the Board of Governors
of the Federal Reserve System or any other regulation of such Board or to
violate the Exchange Act, in each case as in effect on the date or dates of
such borrowing and such use of proceeds.

2.6      SPECIAL PROVISIONS GOVERNING EURODOLLAR RATE LOANS.

         Notwithstanding any other provision of this Agreement to the
contrary, the following provisions shall govern with respect to Eurodollar
Rate Loans as to the matters covered:

         (A) DETERMINATION OF APPLICABLE INTEREST RATE. As soon as practicable
after 10:00 A.M. (New York City time) on each Interest Rate Determination
Date, Administrative Agent shall determine (which determination shall, absent
manifest error, be final, conclusive and binding upon all parties) the
interest rate that shall apply to the Eurodollar Rate Loans for which an
interest rate is then being determined for the applicable Interest Period and
shall promptly give notice thereof (in writing or by telephone confirmed in
writing) to Company or Finance Sub, as applicable, and each Lender.

                                      45

<PAGE>   54

         (B) INABILITY TO DETERMINE APPLICABLE INTEREST RATE. In the event
that Administrative Agent shall have determined (which determination shall be
final and conclusive and binding upon all parties hereto), on any Interest
Rate Determination Date with respect to any Eurodollar Rate Loans, that by
reason of circumstances affecting the interbank Eurodollar market adequate and
fair means do not exist for ascertaining the interest rate applicable to such
Loans on the basis provided for in the definition of Adjusted Eurodollar Rate,
Administrative Agent shall on such date give notice (by telefacsimile or by
telephone confirmed in writing) to Company or Finance Sub, as applicable, and
each Lender of such determination, whereupon (i) no Loans may be made as, or
converted to, Eurodollar Rate Loans until such time as Administrative Agent
notifies Company or Finance Sub, as applicable, and Lenders that the
circumstances giving rise to such notice no longer exist and (ii) any Notice
of Borrowing or Notice of Conversion/Continuation given by either Borrower
with respect to the Loans in respect of which such determination was made
shall be deemed to be rescinded by such Borrower.

         (C) ILLEGALITY OR IMPRACTICABILITY OF EURODOLLAR RATE LOANS. In the
event that on any date any Lender shall have determined (which determination
shall be final and conclusive and binding upon all parties hereto but shall be
made only after consultation with Company and Administrative Agent) that the
making, maintaining or continuation of its Eurodollar Rate Loans (i) has
become unlawful as a result of compliance by such Lender in good faith with
any law, treaty, governmental rule, regulation, guideline or order (or would
conflict with any such treaty, governmental rule, regulation, guideline or
order not having the force of law even though the failure to comply therewith
would not be unlawful) or (ii) has become impracticable, or would cause such
Lender material hardship, as a result of contingencies occurring after the
date of this Agreement which materially and adversely affect the interbank
Eurodollar market, then, and in any such event, such Lender shall be an
"AFFECTED LENDER" and it shall on that day give notice (by telefacsimile or by
telephone confirmed in writing) to Borrowers and Administrative Agent of such
determination (which notice Administrative Agent shall promptly transmit to
each other Lender). Thereafter (a) the obligation of the Affected Lender to
make Loans as, or to convert Loans to, Eurodollar Rate Loans shall be
suspended until such notice shall be withdrawn by the Affected Lender, (b) to
the extent such determination by the Affected Lender relates to a Eurodollar
Rate Loan then being requested by a Borrower pursuant to a Notice of Borrowing
or a Notice of Conversion/Continuation, the Affected Lender shall make such
Loan as (or convert such Loan to, as the case may be) a Base Rate Loan, (c)
the Affected Lender's obligation to maintain its outstanding Eurodollar Rate
Loans (the "AFFECTED LOANS") shall be terminated at the earlier to occur of
the expiration of the Interest Period then in effect with respect to the
Affected Loans or when required by law, and (d) the Affected Loans shall
automatically convert into Base Rate Loans on the date of such termination.
Notwithstanding the foregoing, to the extent a determination by an Affected
Lender as described above relates to a Eurodollar Rate Loan then being
requested by a Borrower pursuant to a Notice of Borrowing or a Notice of
Conversion/Continuation, such Borrower shall have the option, subject to the
provisions of subsection 2.6D, to rescind such Notice of Borrowing or Notice
of Conversion/Continuation as to all Lenders by giving notice (by
telefacsimile or by telephone confirmed in writing) to Administrative Agent of
such rescission on the date on which the Affected Lender gives notice of its
determination as described above (which notice of rescission Administrative
Agent shall promptly transmit to each other Lender). Except as provided in the
immediately preceding sentence, nothing in this subsection 2.6C shall affect
the obligation of any Lender other than an

                                      46

<PAGE>   55

Affected Lender to make or maintain Loans as, or to convert Loans to,
Eurodollar Rate Loans in accordance with the terms of this Agreement.

         (D) COMPENSATION FOR BREAKAGE OR NON-COMMENCEMENT OF INTEREST
PERIODS. Each Borrower shall compensate each Lender, upon written request by
that Lender (which request shall set forth the basis for requesting such
amounts), for all reasonable losses, expenses and liabilities (including any
interest paid by that Lender to lenders of funds borrowed by it to make or
carry its Eurodollar Rate Loans and any loss, expense or liability sustained
by that Lender in connection with the liquidation or re-employment of such
funds) which that Lender may sustain: (i) if for any reason (other than a
default by that Lender) a borrowing of any Eurodollar Rate Loan does not occur
on a date specified therefor in a Notice of Borrowing or a telephonic request
for borrowing, or a conversion to or continuation of any Eurodollar Rate Loan
does not occur on a date specified therefor in a Notice of
Conversion/Continuation or a telephonic request for conversion or
continuation, (ii) if any prepayment (including any prepayment pursuant to
subsection 2.4B(i)) or other principal payment or any conversion of any of its
Eurodollar Rate Loans occurs on a date prior to the last day of an Interest
Period applicable to that Loan, (iii) if any prepayment of any of its
Eurodollar Rate Loans is not made on any date specified in a notice of
prepayment given by such Borrower, or (iv) as a consequence of any other
default by such Borrower in the repayment of its Eurodollar Rate Loans when
required by the terms of this Agreement.

         (E) BOOKING OF EURODOLLAR RATE LOANS. Any Lender may make, carry or
transfer Eurodollar Rate Loans at, to, or for the account of any of its branch
offices or the office of an Affiliate of that Lender.

         (F) ASSUMPTIONS CONCERNING FUNDING OF EURODOLLAR RATE LOANS.
Calculation of all amounts payable to a Lender under this subsection 2.6 and
under subsection 2.7A shall be made as though that Lender had actually funded
each of its relevant Eurodollar Rate Loans through the purchase of a
Eurodollar deposit bearing interest at the rate obtained pursuant to clause
(i) of the definition of Adjusted Eurodollar Rate in an amount equal to the
amount of such Eurodollar Rate Loan and having a maturity comparable to the
relevant Interest Period and through the transfer of such Eurodollar deposit
from an offshore office of that Lender to a domestic office of that Lender in
the United States of America; provided, however, that each Lender may fund
each of its Eurodollar Rate Loans in any manner it sees fit and the foregoing
assumptions shall be utilized only for the purposes of calculating amounts
payable under this subsection 2.6 and under subsection 2.7A.

         (G) EURODOLLAR RATE LOANS AFTER DEFAULT. After the occurrence of and
during the continuation of a Potential Event of Default or an Event of Default
and upon notice to such effect to Borrowers from the Administrative Agent or
Requisite Lenders which notice may be delivered after delivery of a Notice of
Borrowing or Notice of Conversion/Continuation but prior to the funding or
continuation or conversion of Loans pursuant thereto, (i) no Borrower may
elect to have a Loan be made or maintained as, or converted to, a Eurodollar
Rate Loan after the expiration of any Interest Period then in effect for that
Loan and (ii) subject to the provisions of subsection 2.6D, any Notice of
Borrowing or Notice of Conversion/Continuation given by a Borrower with
respect to a requested borrowing or conversion/continuation that has not yet
occurred shall be deemed to be rescinded by such Borrower.

2.7      INCREASED COSTS; TAXES; CAPITAL ADEQUACY.

         (A) COMPENSATION FOR INCREASED COSTS AND TAXES. Subject to the
provisions of subsection 2.7B (which shall be controlling with respect to the
matters covered thereby), in the event that any Lender shall determine (which
determination shall, absent manifest error, be final and conclusive and
binding upon all parties hereto) that any law, treaty or governmental rule,
regulation or order, or any change therein or in the interpretation,
administration or application thereof (including the introduction of any new
law, treaty or governmental rule, regulation or order), or any determination
of a court or governmental authority, in each case that becomes effective
after the date hereof, or compliance by such Lender with any guideline,
request or directive issued or made after the date hereof by any central bank
or other governmental or quasi-governmental authority (whether or not having
the force of law):

                  (i)      subjects such Lender (or its applicable lending
         office) to any additional Tax (other than any Tax on the overall net
         income of such Lender) with respect to this Agreement or any of its
         obligations hereunder or any payments to such Lender (or its
         applicable lending office) of principal, interest, fees or any other
         amount payable hereunder;

                  (ii)     imposes, modifies or holds applicable any reserve
         (including any marginal, emergency, supplemental, special or other
         reserve), special deposit, compulsory loan, FDIC insurance or similar
         requirement against assets held by, or deposits or other liabilities
         in or for the account of, or advances or loans by, or other credit
         extended by, or any other acquisition of funds by, any office of such
         Lender (other than any such reserve or other requirements with
         respect to Eurodollar Rate Loans that are reflected in the definition
         of Adjusted Eurodollar Rate); or

                  (iii)    imposes any other condition (other than with
         respect to a Tax matter) on or affecting such Lender (or its
         applicable lending office) or its obligations hereunder or the
         interbank Eurodollar market;

and the result of any of the foregoing is to increase the cost to such Lender
of agreeing to make, making or maintaining Loans hereunder or to reduce any
amount received or receivable by such Lender (or its applicable lending
office) with respect thereto; then, in any such case, the applicable Borrower
shall promptly pay to such Lender, upon receipt of the statement referred to
in the next sentence, such additional amount or amounts (in the form of an
increased rate of, or a different method of calculating, interest or otherwise
as such Lender in its sole discretion shall determine) as may be necessary to
compensate such Lender for any such increased cost or reduction in amounts
received or receivable hereunder. Such Lender shall deliver as soon as
reasonably practicable to each Borrower (with a copy to Administrative Agent)
a written statement, setting forth in reasonable detail the basis for
calculating the additional amounts owed to such Lender by such Borrower under
this subsection 2.7A, which statement shall be conclusive and binding upon all
parties hereto absent manifest error.

(B) WITHHOLDING OF TAXES.

                  (i)      Payments to Be Free and Clear. All sums payable by
         each Borrower under this Agreement and the other Loan Documents shall
         (except to the extent required by law) be paid free and clear of, and
         without any deduction or withholding on account of, any Tax (other
         than a Tax on the overall net income of any Lender) imposed, levied,
         collected, withheld or assessed by or within the United States of
         America or any political subdivision in or of the United States of
         America or any other jurisdiction from or to which a payment is made
         by or on behalf of Company or by any federation or organization of
         which the United States of America or any such jurisdiction is a
         member at the time of payment.

                  (ii)     Grossing-up of Payments. If a Borrower or any other
         Person is required by law to make any deduction or withholding on
         account of any such Tax from any sum paid or payable by such Borrower
         to Administrative Agent or any Lender under any of the Loan
         Documents:

                           (a)      Such Borrower shall notify Administrative
                  Agent of any such requirement or any change in any such
                  requirement as soon as Company becomes aware of it;

                           (b)      Such Borrower shall pay any such Tax
                  before the date on which penalties attach thereto, such
                  payment to be made (if the liability to pay is imposed on
                  such Borrower) for its own account or (if that liability is
                  imposed on Administrative Agent or such Lender, as the case
                  may be) on behalf of and in the name of Administrative Agent
                  or such Lender;

                           (c)      the sum payable by such Borrower in
                  respect of which the relevant deduction, withholding or
                  payment is required shall be increased to the extent
                  necessary to ensure that, after the making of that
                  deduction, withholding or payment, Administrative Agent or
                  such Lender, as the case may be, receives on the due date a
                  net sum equal to what it would have received had no such
                  deduction, withholding or payment been required or made; and

                           (d)      within 30 days after paying any sum from
                  which it is required by law to make any deduction or
                  withholding, and within 30 days after the due date of
                  payment of any Tax which it is required by clause (b) above
                  to pay, such Borrower shall deliver to Administrative Agent
                  evidence satisfactory to the other affected parties of such
                  deduction, withholding or payment and of the remittance
                  thereof to the relevant taxing or other authority;

         provided that no such additional amount shall be required to be paid
         to any Lender under clause (c) above except to the extent that any
         change after the date hereof (in the case of each Lender listed on
         the signature pages hereof) or after the date of the Assignment
         Agreement pursuant to which such Lender became a Lender (in the case
         of each other Lender) in any such requirement for a deduction,
         withholding or payment as is mentioned therein shall result in an
         increase in the rate of such deduction, withholding or payment

                                      49

<PAGE>   58

         from that in effect at the date of this Agreement or at the date of
         such Assignment Agreement, as the case may be, in respect of payments
         to such Lender.

                  (iii)    Evidence of Exemption from U.S. Withholding Tax.

                           (a)      Each Lender that is not a U.S. person as
                  defined in Section 7701(a)(30) of the Code (for purposes of
                  this subsection 2.7B(iii), a "NON-US LENDER") shall deliver
                  to Administrative Agent for transmission to Borrowers, on or
                  prior to the Closing Date (in the case of each Lender listed
                  on the signature pages hereof) or on or prior to the date of
                  the Assignment Agreement pursuant to which it becomes a
                  Lender (in the case of each other Lender), and at such other
                  times as may be necessary in the determination of Borrowers
                  or Administrative Agent (each in the reasonable exercise of
                  its discretion), (1) two original copies of Internal Revenue
                  Service Form 1001 or 4224 (or any successor forms), properly
                  completed and duly executed by such Lender, together with
                  any other certificate or statement of exemption required
                  under the Internal Revenue Code or the regulations issued
                  thereunder to establish that such Lender is exempt from
                  United States federal income tax with respect to any
                  payments to such Lender of principal, interest, fees or
                  other amounts payable under any of the Loan Documents or (2)
                  if such Lender is not a "bank" or other Person described in
                  Section 881(c)(3) of the Internal Revenue Code and cannot
                  deliver either Internal Revenue Service Form 1001 or 4224
                  pursuant to clause (1) above, a Certificate re Non-Bank
                  Status together with two original copies of Internal Revenue
                  Service Form W-8 (or any successor form), properly completed
                  and duly executed by such Lender, together with any other
                  certificate or statement of exemption required under the
                  Internal Revenue Code or the regulations issued thereunder
                  to establish that such Lender is not subject to deduction or
                  withholding of United States federal income tax with respect
                  to any payments to such Lender of interest payable under any
                  of the Loan Documents.

                           (b)      Each Lender required to deliver any forms,
                  certificates or other evidence with respect to United States
                  federal income tax withholding matters pursuant to
                  subsection 2.7B(iii)(a) hereby agrees, from time to time
                  after the initial delivery by such Lender of such forms,
                  certificates or other evidence, whenever a lapse in time or
                  change in circumstances renders such forms, certificates or
                  other evidence obsolete or inaccurate in any material
                  respect, that such Lender shall promptly (1) deliver to
                  Administrative Agent for transmission to Borrowers two new
                  original copies of Internal Revenue Service Form 1001 or
                  4224, or a Certificate re Non-Bank Status and two original
                  copies of Internal Revenue Service Form W-8, as the case may
                  be, properly completed and duly executed by such Lender,
                  together with any other certificate or statement of
                  exemption required in order to confirm or establish that
                  such Lender is not subject to deduction or withholding of
                  United States federal income tax with respect to payments to
                  such Lender under the Loan Documents or (2) notify
                  Administrative Agent and Borrowers of its inability to
                  deliver any such forms, certificates or other evidence.

<PAGE>   59

                           (c)      Borrowers shall not be required to pay any
                  additional amount to any Non-US Lender under clause (c) of
                  subsection 2.7B(ii) if such Lender shall have failed to
                  satisfy the requirements of clause (a) or (b)(1) of this
                  subsection 2.7B(iii); provided that if such Lender shall
                  have satisfied the requirements of subsection 2.7B(iii)(a)
                  on the Closing Date (in the case of each Lender listed on
                  the signature pages hereof) or on the date of the Assignment
                  Agreement pursuant to which it became a Lender (in the case
                  of each other Lender), nothing in this subsection
                  2.7B(iii)(c) shall relieve Borrowers of its obligation to
                  pay any additional amounts pursuant to clause (c) of
                  subsection 2.7B(ii) in the event that, as a result of any
                  change in any applicable law, treaty or governmental rule,
                  regulation or order, or any change in the interpretation,
                  administration or application thereof, such Lender is no
                  longer properly entitled to deliver forms, certificates or
                  other evidence at a subsequent date establishing the fact
                  that such Lender is not subject to withholding as described
                  in subsection 2.7B(iii)(a).

                  (iv)     Payment of Refunds.  If the Administrative Agent or
         any Lender receives a refund in respect of any Taxes paid by a
         Borrower pursuant to Section 2.7(B)(ii)(b), which in the reasonable
         judgment of such Lender is allocable to such payment, it shall
         promptly pay such refund, together with any other amounts paid by the
         relevant Borrower in connection with such Taxes, to such Borrower,
         net of all out-of-pocket expenses of such Lender incurred in
         obtaining such refund, provided, however, that such Borrower agrees
         to promptly return such refund to the Administrative Agent or the
         applicable Lender, as the case may be, if it receives notice from the
         Administrative Agent or applicable Lender that such Administrative
         Agent or Lender is required to repay such refund.

         (C) CAPITAL ADEQUACY ADJUSTMENT. If any Lender shall have determined
that the adoption, effectiveness, phase-in or applicability after the date
hereof of any law, rule or regulation (or any provision thereof) regarding
capital adequacy, or any change therein or in the interpretation or
administration thereof by any governmental authority, central bank, the
National Association of Insurance Commissioners, or comparable agency charged
with the interpretation or administration thereof, or compliance by any Lender
(or its applicable lending office) with any guideline, request or directive
regarding capital adequacy (whether or not having the force of law) of any
such governmental authority, central bank, the National Association of
Insurance Commissioners or comparable agency, has or would have the effect of
reducing the rate of return on the capital of such Lender or any corporation
controlling such Lender as a consequence of, or with reference to, such
Lender's Loans or participations therein or other obligations hereunder with
respect to the Loans to a level below that which such Lender or such
controlling corporation could have achieved but for such adoption,
effectiveness, phase-in, applicability, change or compliance (taking into
consideration the policies of such Lender or such controlling corporation with
regard to capital adequacy) by an amount which such Lender deems material,
then from time to time, within five Business Days after receipt by Borrowers
from such Lender of the statement referred to in the next sentence, the
applicable Borrower shall pay to such Lender such additional amount or amounts
as will compensate such Lender or such controlling corporation on an after-tax
basis for such reduction. Such Lender shall deliver to Borrowers (with a copy
to Administrative Agent) a written statement, setting forth in reasonable
detail the basis of the calculation of such additional amounts, which
statement shall be conclusive and binding upon all

                                      51

<PAGE>   60

parties hereto absent manifest error; provided that Borrowers shall not be
required to compensate a Lender pursuant to this subsection 2.7C for any
amounts incurred more than six months prior to the date that such Lender
notifies Borrowers of such Lender's intention to claim compensation therefor,
except that, if the circumstances giving rise to such claim have a retroactive
effect, then such six-month period shall be extended to include the period of
such retroactive effect.

         (D) SUBSTITUTE LENDERS. In the event Company is required under the
provisions of this subsection 2.7 to make payments in a material amount to any
Lender or in the event any Lender fails to lend to Borrowers in accordance
with this Agreement, Borrowers may, so long as no Event of Default or
Potential Event of Default shall have occurred and be continuing, elect to
terminate such Lender as a party to this Agreement; provided that,
concurrently with such termination, (i) each Borrower shall pay that Lender
all principal, interest and fees and other amounts (including without
limitation, amounts, if any, owed under this subsection 2.7) owed to such
Lender through such date of termination, (ii) another financial institution
satisfactory to Administrative Agent (or if Administrative Agent is also the
Lender to be terminated, the successor Administrative Agent) shall agree, as
of such date, to become a Lender for all purposes under this Agreement
(whether by assignment or amendment) and to assume all obligations of the
Lender to be terminated as of such date, and (iii) all documents and
supporting materials necessary, in the judgment of Administrative Agent (or if
Administrative Agent is also the Lender to be terminated, the successor
Administrative Agent), to evidence the substitution of such Lender shall have
been received and approved by Administrative Agent as of such date.

2.8      OBLIGATION OF LENDERS TO MITIGATE.

         Each Lender agrees that, as promptly as practicable after the officer
of such Lender responsible for administering the Loans of such Lender becomes
aware of the occurrence of an event or the existence of a condition that would
cause such Lender to become an Affected Lender or that would entitle such
Lender to receive payments under subsection 2.7, it will, to the extent not
inconsistent with the internal policies of such Lender and any applicable
legal or regulatory restrictions, use reasonable efforts (i) to maintain the
affected Loans of such Lender through another lending office of such Lender,
or (ii) take such other measures as such Lender may deem reasonable, if as a
result thereof the circumstances which would cause such Lender to be an
Affected Lender would cease to exist or the additional amounts which would
otherwise be required to be paid to such Lender pursuant to subsection 2.7
would be materially reduced and if, as determined by such Lender in its sole
discretion, the maintaining of such Loans through such other lending office or
in accordance with such other measures, as the case may be, would not
otherwise materially adversely affect such Loans or the interests of such
Lender; provided that such Lender will not be obligated to utilize such other
lending office pursuant to this subsection 2.8 unless Company agrees to pay
all incremental expenses incurred by such Lender as a result of utilizing such
other lending office as described in clause (i) above. A certificate as to the
amount of any such expenses payable by Company pursuant to this subsection 2.8
(setting forth in reasonable detail the basis for requesting such amount)
submitted by such Lender to Company (with a copy to Administrative Agent)
shall be conclusive absent manifest error.

                                  SECTION 4.
                  BORROWERS' REPRESENTATIONS AND WARRANTIES

         In order to induce Lenders to enter into this Agreement and to
continue the Loans and to induce other Lenders to purchase participations
therein, each Borrower represents and warrants to each Lender, on the date of
this Agreement, that the following statements are true, correct and complete:

4.1      ORGANIZATION, POWERS, QUALIFICATION, GOOD STANDING, BUSINESS AND
         SUBSIDIARIES.

         (A)      ORGANIZATION AND POWERS. Each Loan Party is duly organized,
validly existing and in good standing under the laws of its jurisdiction of
organization as specified in Schedule 4.1

                                      55

<PAGE>   64

annexed hereto. Each Loan Party has all requisite power and authority to own
and operate its properties, to carry on its business as now conducted and as
proposed to be conducted, to enter into the Loan Documents to which it is a
party and to carry out the transactions contemplated thereby.

         (B) QUALIFICATION AND GOOD STANDING. Each Loan Party is qualified to
do business and in good standing in every jurisdiction where its assets are
located and wherever necessary to carry out its business and operations,
except in jurisdictions where the failure to be so qualified or in good
standing has not had and could not reasonably be expected to have a Material
Adverse Effect.

         (C) CONDUCT OF BUSINESS. Loan Parties are engaged only in the
businesses permitted to be engaged in pursuant to subsection 6.14.

         (D) SUBSIDIARIES. All of the Subsidiaries of Company are identified
in Schedule 4.1 annexed hereto, as said Schedule 4.1 may be supplemented from
time to time pursuant to the provisions of subsection 5.1(xvi). The Capital
Stock of each of the Subsidiaries of Company identified in Schedule 4.1
annexed hereto (as so supplemented) is duly authorized, validly issued, fully
paid and nonassessable and none of such Capital Stock constitutes Margin
Stock. Each of the Subsidiaries of Company identified in Schedule 4.1 annexed
hereto (as so supplemented) is duly organized, validly existing and in good
standing under the laws of its respective jurisdiction of organization set
forth therein, has all requisite power and authority to own and operate its
properties and to carry on its business as now conducted and as proposed to be
conducted, and is qualified to do business and in good standing in every
jurisdiction where its assets are located and wherever necessary to carry out
its business and operations, in each case except where failure to be so
qualified or in good standing or a lack of such corporate power and authority
has not had and could not reasonably be expected to have a Material Adverse
Effect. Schedule 4.1 annexed hereto (as so supplemented) correctly sets forth
the ownership interest of Company and each of its Subsidiaries in each of the
Subsidiaries of Company identified therein.

         (E) REGULATORY AUTHORIZATIONS.

                  (i)      Licenses.  Except as set forth in Part I of
         Schedule 4.1E annexed hereto as such Schedule 4.1E may be
         supplemented from time to time pursuant to the provisions of
         subsection 5.1(xvii), each of the Loan Parties has obtained all
         licenses, permits, certifications or other authorizations required by
         the Communications Regulatory Authorities under the Communications
         Act, State Law and local law in order to carry out its business and
         operations as presently conducted and as proposed to be conducted,
         including the provision of the telecommunications services set forth
         in any Licenses except to the extent the failure to obtain such
         licenses, permits, certifications or other authorizations would not
         individually or in the aggregate have a Material Adverse Effect. Part
         II of Schedule 4.1E (as so supplemented) annexed hereto accurately
         lists all Licenses, including their expiration dates, held by each of
         the Loan Parties as of the date of this Agreement.  Each such License
         was duly and validly issued by the FCC, the appropriate State PUC or
         local governmental authority pursuant to procedures which materially
         comply with all requirements of all applicable federal, state or
         local laws and is in full force and effect except to the extent the
         failure to be in full force and effect

                                      56

<PAGE>   65

         could not reasonably be expected individually or in the aggregate to
         have a Material Adverse Effect.  None of the Loan Parties has any
         knowledge of the occurrence of any event or the existence of any
         circumstance which, in the reasonable judgment of such Loan Party, is
         likely to lead to the revocation, suspension, non-renewal or adverse
         modification of any material Licenses.

                  (ii)     Compliance with Applicable Laws.  The Loan Parties
         are in compliance with the terms of all applicable Regulations except
         to the extent noncompliance could not reasonably be expected
         individually or in the aggregate to have a Material Adverse Effect.
         Each of the Loan Parties has duly filed in a timely manner all
         filings, including tariff filings, required by the FCC, any State PUC
         or any local governmental authority to be filed by such Loan Party as
         a precondition to the provision of the telecommunications services
         which it offers except to the extent failure to do so could not
         reasonably be expected individually or in the aggregate to have a
         Material Adverse Effect.  None of the Loan Parties is a party as a
         defendant to, or is aware of any overt threat of, any litigation,
         proceeding, action, notice of violation or apparent liability, order
         to show cause, order of forfeiture, formal or informal complaint,
         inquiry or investigation by or before the FCC, any State PUC or any
         local governmental authority with jurisdiction over the services
         which it offers as to which there is a reasonable possibility of an
         adverse determination and, which if adversely determined, could
         reasonably be expected, individually or in the aggregate, to have a
         Material Adverse Effect.

4.2      AUTHORIZATION, ETC.

         (A) AUTHORIZATION. The execution, delivery and performance of the
Loan Documents have been duly authorized by all necessary action on the part
of each Loan Party that is a party thereto.

Parties of the Loan Documents to which they are parties and the consummation
of the transactions contemplated by the Loan Documents do not and will not (i)
violate any provision of any law or any governmental rule or regulation

Documents of any Loan Party or any of its Subsidiaries or any order, judgment
or decree of any court or other agency of government binding on any Loan Party
or any of its Subsidiaries, (ii) conflict with, result in a breach of or
constitute (with due notice or lapse of time or both) a default under any

any approval or consent of any Person under any Contractual Obligation of any
Loan Party or any of its Subsidiaries, except for such approvals or consents

in the case of the issuance and sale of certain other Required Junior Capital
or Subsequent Junior Capital, approval by the stockholders of Company and any

         (C) GOVERNMENTAL CONSENTS. The execution, delivery and performance by
Loan Parties of the Loan Documents to which they are parties and the

         (D) BINDING OBLIGATION. Each of the Loan Documents has been duly
executed and delivered by each Loan Party that is a party thereto and is the
legally valid and binding obligation of such Loan Party, enforceable against
such Loan Party in accordance with its respective terms, except as may be
limited by bankruptcy, insolvency, reorganization, moratorium or similar laws
relating to or limiting creditors' rights generally or by equitable principles
relating to enforceability.

4.3      FINANCIAL CONDITION.

         Company has heretofore delivered to Lenders, at Lenders' request, the
following financial statements and information: (i) the audited consolidated
balance sheets of Company and its Subsidiaries as at December 31, 1999 and the
related consolidated statements of income, stockholders' equity and cash flows

Contingent Obligation, contingent liability or liability for taxes, long-term
lease or unusual forward or long-term commitment that is not reflected in the
foregoing financial statements or the notes thereto and which in any such case
is material in relation to the business, operations, properties, assets,
condition (financial or otherwise) or prospects of Company or any of its
Subsidiaries.

4.4      NO MATERIAL ADVERSE CHANGE; NO RESTRICTED JUNIOR PAYMENTS.

         Since June 30, 2000, no event or change has occurred that has caused

lease, sublease or assignment is in full force and effect and no Borrower has
knowledge of any material default that has occurred and is continuing
thereunder, and each such agreement constitutes the legally valid and binding

Party or any of its Subsidiaries) at law or in equity, or before or by any
federal, state, municipal or other governmental department, commission, board,
bureau, agency or instrumentality, domestic or foreign (including any
Environmental Claims) that are pending or, to the knowledge of either
Borrower, threatened against any Loan Party or any of its Subsidiaries or any
property of any Loan Party or any of its Subsidiaries and that, individually
or in the aggregate, could reasonably be expected to result in a Material

Effect, or (ii) is subject to or in default with respect to any final

when due and payable. Neither Borrower knows of any material proposed tax
assessment against any Loan Party or any of its Subsidiaries which is not
being actively contested by such Loan Party or such Subsidiary in good faith

appropriate provisions, if any, as shall be required in conformity with GAAP
shall have been made or provided therefor.

4.8      PERFORMANCE OF AGREEMENTS; MATERIALLY ADVERSE AGREEMENTS; MATERIAL
         CONTRACTS.

         (A) No Loan Party nor any of its Subsidiaries is in default in the
performance, observance or fulfillment of any of the obligations, covenants or
conditions contained in any of its Contractual Obligations, and no condition
exists that, with the giving of notice or the lapse of time or both, would
constitute such a default, except where the consequences, direct or indirect,
of such default or defaults, if any, could not reasonably be expected to have
a Material Adverse Effect.

         (B) No Loan Party nor any of its Subsidiaries is a party to or is
otherwise subject to any agreements or instruments or any charter or other
internal restrictions which, individually or in the aggregate, could
reasonably be expected to result in a Material Adverse Effect.

4.9      GOVERNMENTAL REGULATION.

         No Loan Party nor any of its Subsidiaries is subject to regulation
under the Public Utility Holding Company Act of 1935, the Federal Power Act,
the Interstate Commerce Act or the Investment Company Act of 1940 or under any
other federal or state statute or regulation (other than Regulation X of the
Board of Governors of the Federal Reserve System) which may limit its ability
to incur Indebtedness or which may otherwise render all or any portion of the
Obligations unenforceable.

4.10     SECURITIES ACTIVITIES.

         No Loan Party nor any of its Subsidiaries (i) is engaged principally,
or as one of its important activities, in the business of extending credit for
the purpose of purchasing or carrying any Margin Stock or (ii) will use the
proceeds of any Loans to purchase Margin Stock or in any manner whatsoever to
cause a violation of Regulation U of the Board of Governors of the Federal
Reserve System.

         (A) Each Loan Party and each of their respective ERISA Affiliates are
in material compliance with all applicable provisions and requirements of
ERISA and the regulations and published interpretations thereunder with
respect to each Employee Benefit Plan, and have performed all their
obligations under each Employee Benefit Plan, except where the failure to
comply or perform could not reasonably be expected to result in a Material
Adverse Effect. Each Employee Benefit Plan which is intended to qualify under
Section 401(a) of the Internal Revenue Code has received a favorable
determination letter from the IRS and nothing, to the best knowledge of the
Loan Parties, has occurred with respect to the operation of an Employee
Benefit Plan since the date of such letter which would reasonably be expected
to cause it to be no longer valid or effective.

                                      60

<PAGE>   69

         (B) No ERISA Event has occurred or is reasonably expected to occur
that could reasonably be expected to have a Material Adverse Effect.

         (C) As of the most recent valuation date for any Pension Plan, the
amount of unfunded benefit liabilities (as defined in Section 4001(a)(18) of
ERISA), individually or in the aggregate for all Pension Plans (excluding for
purposes of such computation any Pension Plans with respect to which assets
exceed benefit liabilities), does not exceed an amount, which if immediately
due and payable, could reasonably be expected to have a Material Adverse
Effect.

         (D) As of the most recent valuation date for each Multiemployer Plan
for which the actuarial report has been provided to Borrowers, the potential
liability of Loan Parties and their respective ERISA Affiliates for a complete
withdrawal from such Multiemployer Plan (within the meaning of Section 4203 of
ERISA), when aggregated with such potential liability for a complete
withdrawal from all Multiemployer Plans, could not reasonably be expected to
have a Material Adverse Effect.

4.12     CERTAIN FEES.

         No broker's or finder's fee or commission will be payable with
respect to this Agreement or any of the transactions contemplated hereby, and
Borrowers hereby indemnify Lenders against, and agree that each of them will
hold Lenders harmless from, any claim, demand or liability for any such
broker's or finder's fees alleged to have been incurred in connection herewith
or therewith and any expenses (including reasonable fees, expenses and
disbursements of counsel) arising in connection with any such claim, demand or
liability.

4.13     ENVIRONMENTAL PROTECTION.

                  (i)      No Loan Party nor any of its Subsidiaries nor any
         of their respective Facilities or operations are subject to any
         outstanding written order, consent decree or settlement agreement
         with any Person relating to (a) any Environmental Law, (b) any
         Environmental Claim, or (c) any Hazardous Materials Activity that,
         individually or in the aggregate, could reasonably be expected to
         have a Material Adverse Effect;

                  (ii)     No Loan Party nor any of its Subsidiaries has
         received any letter or request for information under Section 104 of
         the Comprehensive Environmental Response, Compensation, and Liability
         Act (42 U.S.C. Section 9604) or any comparable state law;

                  (iii)    There are and, to Borrowers' knowledge, have been
         no conditions, occurrences, or Hazardous Materials Activities which
         could reasonably be expected to form the basis of an Environmental
         Claim against any Loan Party or any of its Subsidiaries that,
         individually or in the aggregate, could reasonably be expected to
         have a Material Adverse Effect;

                  (iv)     Except as could not, individually or in the
         aggregate, reasonably be expected to have a Material Adverse Effect,
         no Loan Party nor any of its Subsidiaries nor, to Borrower's
         knowledge, any predecessor of Company or any of its Subsidiaries has
         filed any notice under any Environmental Law indicating past or
         present treatment of

         treatment, storage or disposal of hazardous waste, as defined under
         40 C.F.R. Parts 260-270 or any state equivalent;

                  (v)      Compliance with all current or, to the best
         knowledge of each Loan Party, reasonably foreseeable future
         requirements pursuant to or under Environmental Laws could not,
         individually or in the aggregate, be reasonably expected to have a
         Material Adverse Effect.

         Notwithstanding anything in this subsection 4.13 to the contrary, no
event or condition has occurred or is occurring with respect to any Loan Party
or any of its Subsidiaries relating to any Environmental Law, any Release of
Hazardous Materials, or any Hazardous Materials Activity which individually or
in the aggregate has had or could reasonably be expected to have a Material
Adverse Effect.

         Except as set forth in Schedule 4.14 annexed hereto, no Loan Party or
any of its Subsidiaries is as of the date hereof, a party to any collective

<PAGE>   87

goods or accounts receivable) of Borrowers or any of its Restricted
Subsidiaries, whether now owned or hereafter acquired, or any income or
profits therefrom, or file or permit the filing of, or permit to remain in
effect, any financing statement or other similar notice of any Lien with
respect to any such property, asset, income or profits under the Uniform
Commercial Code of any State or under any similar recording or notice statute,
except:

                  (i)      Permitted Encumbrances;

                  (ii)     Liens granted pursuant to the Collateral Documents;

                  (iii)    Existing Liens described in Schedule 6.2 annexed

                  (iv)     Liens securing Indebtedness permitted pursuant to
         subsection 6.1(vi) so long as such Liens relate solely to the assets
         financed with such Indebtedness; provided that purchase money
         Indebtedness permitted pursuant to subsection 6.1(vi) may also be
         secured by subordinated Liens on the Collateral if the holder of such
         Indebtedness enters into an intercreditor agreement in form and
         substance satisfactory to Requisite Lenders in their sole discretion
         pursuant to which (a) such Liens are subordinate to the Liens on the
         Collateral granted to the Administrative Agent for the benefit of
         Lenders and (b) any deficiency claims of such holder related to such
         Indebtedness are subordinated to the Obligations.

         (B) NO FURTHER NEGATIVE PLEDGES. Except with respect to specific
property encumbered to secure payment of particular Indebtedness (including
Indebtedness permitted under subsection 6.1(vi)) or to be sold pursuant to an
executed agreement with respect to an Asset Sale, neither Borrower nor any of
its Restricted Subsidiaries shall enter into any agreement (other than any
agreement prohibiting only the creation of Liens securing Subordinated
Indebtedness) prohibiting the creation or assumption of any Lien upon any of
its properties or assets, whether now owned or hereafter acquired (other than
in connection with Additional Notes permitted under subsection 6.1(iii),
provided that the covenants regarding Liens are no more restrictive to Company
and its Subsidiaries than those in the Existing Senior Note Indentures).

         (C) NO RESTRICTIONS ON SUBSIDIARY DISTRIBUTIONS TO COMPANY OR OTHER
SUBSIDIARIES. Except as provided herein, each Borrower will not, and will not
permit any Restricted Subsidiaries to, create or otherwise cause or suffer to
exist or become effective any consensual encumbrance or restriction of any
kind on the ability of any such Restricted Subsidiary to (i) pay dividends or
make any other distributions on any of such Restricted Subsidiary's Capital
Stock owned by Company or any other Restricted Subsidiary of Company, (ii)
repay or prepay any Indebtedness owed by such Restricted Subsidiary to Company
or any other Restricted Subsidiary of Company, (iii) make loans or advances to
Company or any other Restricted Subsidiary of Company, or (iv) transfer any of
its property or assets to Company or any other Restricted Subsidiary of
Company, except for such encumbrances or restrictions existing under or by
reason of (a) any restrictions existing under the Loan Documents and (b) any
restriction with respect to a Restricted Subsidiary imposed pursuant to an
agreement that has been entered into in connection with the disposition of all
or substantially all of the Capital Stock or assets of such Restricted
Subsidiary.

                  For purposes of determining compliance with this covenant,
         the Consolidated Adjusted EBITDA for ACSI to be included in such
         calculations shall be determined on the basis of (i) Consolidated
         Adjusted EBITDA of ACSI for the Fiscal Quarter ended June 30, 2000,
         (ii) the quarterly average of Consolidated Adjusted EBITDA of ACSI
         for the two-Fiscal Quarter period ended September 30, 2000, (iii) the
         quarterly average of Consolidated Adjusted EBITDA for ACSI for the
         three-Fiscal Quarter period ended December 31, 2000 and (iv)
         thereafter the quarterly average of Consolidated Adjusted EBITDA for
         ACSI for the rolling four Fiscal Quarter period then ended (i.e.,
         Consolidated Adjusted EBITDA of ACSI for the four-Fiscal Quarter
         period then ended divided by four).

         Consolidated Quarterly Revenue for Cybergate and ICP and Minimum
         Consolidated Adjusted EBITDA for the Company and its Restricted
         Subsidiaries shall each be reduced by the corresponding Consolidated
         Quarterly Revenue and Consolidated Adjusted EBITDA attributable to

         hereto as Exhibit XIV.

                  (v)      Minimum Cash Balances.  Borrowers shall not permit
         the Cash Balances of the Company and its Restricted Subsidiaries at

                  (ii)     [Intentionally Omitted].

                  (iii)    Maximum Leverage Ratio. Borrowers shall not permit
         (a) the ratio of Consolidated Senior Debt to Consolidated Annualized
         EBITDA of Company and its Restricted Subsidiaries or (b) the ratio of
         Consolidated Total Debt to Consolidated Annualized EBITDA of Company
         and its Restricted Subsidiaries as of the last day of any Fiscal
         Quarter set forth below to exceed the correlative ratios indicated:

rendering of any service) with any holder of 5% or more of any class of equity
Securities of Company or with any Affiliate of Company or of any such holder,

Subsidiaries, (ii) reasonable and customary fees paid or stock options awarded

Business unless such Subsidiary is a direct or indirect Wholly Owned
Subsidiary of Finance Sub.

6.15     AMENDMENTS OR WAIVERS OF CERTAIN RELATED AGREEMENTS.

         Neither Company nor any of its Subsidiaries will agree to any
amendment to, or request any waiver of (other than a waiver for which no fee
is paid and no other concessions or considerations are granted by Company or
its Subsidiaries), or waive any of their respective rights under, any of the
Related Agreements (other than any amendment or waiver described in the next
succeeding sentence) without in each case obtaining the prior written consent
of Administrative Agent and Requisite Lenders to such amendment, request or
waiver and giving notice to Arranger. Notwithstanding the foregoing, Company

Agreements (i) to cure any ambiguity, to correct or supplement any provision
therein which may be defective or inconsistent with any other provision
therein, or (ii) to comply with the Trust Indenture Act of 1939, as amended,
or (iii) to make modifications of a technical or clarifying nature or which
are no less favorable to the Lenders, in the reasonable opinion of
Administrative Agent and Requisite Lenders, than the provisions of the Related
Agreements as in effect on the Restatement Effective Date (for the purposes of
this subsection 6.15, any amendment, modification or change which would extend
the maturity or reduce the amount of any payment of principal on the Existing
Senior Notes or which would reduce the rate or extend the date for payment of
interest thereon, provided that no fee is payable in connection therewith,
shall be deemed to be an amendment, modification or change that is no less
favorable to the Lenders). Neither Company, Finance Sub nor any Restricted
Subsidiary shall agree to any amendment or any waiver of any of the
Intercompany Loan Documents without the prior written consent of Requisite
Lenders.

in accordance with the terms hereof or thereof, the satisfaction in full of
the Obligations or any other termination of such Collateral Document in
accordance with the terms hereof or thereof) or shall be declared null and
void, or Administrative Agent shall not have or shall cease to have a valid

         Any of the following shall occur, the result of which would
reasonably be expected to have a Material Adverse Effect: (i) any material
License shall be cancelled, terminated, rescinded, revoked, suspended,
materially impaired or otherwise finally denied renewal, or shall cease to be
in full force and effect; (ii) any proceeding shall have been instituted by or

in a material adverse respect or a renewal thereof on terms that materially
and adversely affect the economic or commercial value or usefulness thereof;

Communications Act, State Law or any Regulations, in whole or in part; or

7.14     STOCKHOLDER AND NASDAQ APPROVALS.

         The proxy statement relating to the Stockholder Approval for the
Committed Preferred shall not have been filed with the SEC within 15 days

required NASDAQ approval for the Committed Preferred shall not have been
obtained within 90 days after the Restatement Effective Date;

THEN (i) upon the occurrence of any Event of Default described in subsection
7.6 or 7.7, each of (a) the unpaid principal amount of and accrued interest on
the Loans and (b) all other Obligations shall automatically become immediately
due and payable, without presentment, demand, protest or other requirements of
any kind, all of which are hereby expressly waived by Borrowers and (ii) upon
the occurrence and during the continuation of any other Event of Default,
Administrative Agent shall, upon the request or with the consent of Requisite
Lenders, by written notice to Borrowers, (1) declare all or any portion of the
amounts described in clauses (a) and (b) above to be, and the same shall
forthwith become, immediately due and payable, and the obligation of each
Lender to make any Loan hereunder shall thereupon terminate and (2) subject to
the terms of the Loan Documents, take any and all other actions requested by
Requisite Lenders.

                                      95

<PAGE>   104

         Notwithstanding anything contained in the second preceding paragraph,
if at any time within 60 days after an acceleration of the Loans pursuant to
clause (ii) of such paragraph Borrowers shall pay all arrears of interest and
all payments on account of principal which shall have become due otherwise
than as a result of such acceleration (with interest on principal and, to the
extent permitted by law, on overdue interest, at the rates specified in this
Agreement) and all Events of Default and Potential Events of Default (other
than non-payment of the principal of and accrued interest on the Loans, in
each case which is due and payable solely by virtue of acceleration) shall be
remedied or waived pursuant to subsection 9.6, then Requisite Lenders, by
written notice to Borrowers, may at their option rescind and annul such
acceleration and its consequences; but such action shall not affect any
subsequent Event of Default or Potential Event of Default or impair any right
consequent thereon. The provisions of this paragraph are intended merely to
bind Lenders to a decision which may be made at the election of Requisite
Lenders and are not intended, directly or indirectly, to benefit Borrowers,
and such provisions shall not at any time be construed so as to grant
Borrowers the right to require Lenders to rescind or annul any acceleration
hereunder or to preclude Administrative Agent or Lenders from exercising any
of the rights or remedies available to them under any of the Loan Documents,
even if the conditions set forth in this paragraph are met.

                                  SECTION 8.
                                    AGENTS

8.1      APPOINTMENT.

         (A) APPOINTMENT OF AGENTS. GSCP is hereby appointed Arranger and
Syndication Agent hereunder, and each Lender hereby authorizes Arranger and
Syndication Agent to act as its agent in accordance with the terms of this
Agreement and the other Loan Documents. BNY is hereby appointed Administrative
Agent hereunder and under the other Loan Documents and each Lender hereby
authorizes Administrative Agent to act as its agent in accordance with the
terms of this Agreement and the other Loan Documents. First Union National
Bank is hereby appointed Documentation Agent hereunder and CIT Lending
Services Corporation is hereby appointed Collateral Agent hereunder and each
Lender hereby authorizes Documentation Agent and Collateral Agent to act as
its agent in accordance with the terms of this Agreement and the other Loan
Documents. Each Agent hereby agrees to act upon the express conditions
contained in this Agreement and the other Loan Documents, as applicable. The
provisions of this Section 8 are solely for the benefit of Agents and Lenders
and Borrowers shall have no rights as a third party beneficiaries of any of
the provisions thereof. In performing its functions and duties under this
Agreement, each Agent shall act solely as an agent of Lenders and does not
assume and shall not be deemed to have assumed any obligation towards or
relationship of agency or trust with or for Borrowers or any of their
Subsidiaries. Each of Arranger and Syndication Agent, without consent of or
notice to any party hereto, may assign any and all of its rights or
obligations hereunder to any of its Affiliates. As of the Closing Date, all
obligations of Arranger, Syndication Agent, Documentation Agent and Collateral
Agent hereunder shall terminate other than the obligations of Syndication
Agent under subsection 2.1A(vi).

         (B) APPOINTMENT OF SUPPLEMENTAL COLLATERAL AGENTS. It is the purpose
of this Agreement and the other Loan Documents that there shall be no
violation of any law of any jurisdiction denying or restricting the right of
banking corporations or associations to transact

                                      96

<PAGE>   105

business as agent or trustee in such jurisdiction. It is recognized that in
case of litigation under this Agreement or any of the other Loan Documents,
and in particular in case of the enforcement of any of the Loan Documents, or
in case Administrative Agent deems that by reason of any present or future law
of any jurisdiction it may not exercise any of the rights, powers or remedies
granted herein or in any of the other Loan Documents or take any other action
which may be desirable or necessary in connection therewith, it may be
necessary that Administrative Agent appoint an additional individual or
institution as a separate trustee, co-trustee, collateral agent or collateral
co-agent (any such additional individual or institution being referred to
herein individually as a "SUPPLEMENTAL COLLATERAL AGENT" and collectively as
"SUPPLEMENTAL COLLATERAL AGENTS").

         In the event that Administrative Agent appoints a Supplemental
Collateral Agent with respect to any Collateral, (i) each and every right,
power, privilege or duty expressed or intended by this Agreement or any of the
other Loan Documents to be exercised by or vested in or conveyed to
Administrative Agent with respect to such Collateral shall be exercisable by
and vest in such Supplemental Collateral Agent to the extent, and only to the
extent, necessary to enable such Supplemental Collateral Agent to exercise
such rights, powers and privileges with respect to such Collateral and to
perform such duties with respect to such Collateral, and every covenant and
obligation contained in the Loan Documents and necessary to the exercise or
performance thereof by such Supplemental Collateral Agent shall run to and be
enforceable by either Agent or such Supplemental Collateral Agent, and (ii)
the provisions of this Section 8 and of subsections 9.2 and 9.3 that refer to
Administrative Agent shall inure to the benefit of such Supplemental
Collateral Agent and all references therein to Administrative Agent shall be
deemed to be references to Administrative Agent and/or such Supplemental
Collateral Agent, as the context may require.

         Should any instrument in writing from Company or any other Loan Party
be required by any Supplemental Collateral Agent so appointed by
Administrative Agent for more fully and certainly vesting in and confirming to
him or it such rights, powers, privileges and duties, Company shall, or shall
cause such Loan Party to, execute, acknowledge and deliver any and all such
instruments promptly upon request by Administrative Agent. In case any
Supplemental Collateral Agent, or a successor thereto, shall die, become
incapable of acting, resign or be removed, all the rights, powers, privileges
and duties of such Supplemental Collateral Agent, to the extent permitted by
law, shall vest in and be exercised by Administrative Agent until the
appointment of a new Supplemental Collateral Agent.

8.2      POWERS AND DUTIES; GENERAL IMMUNITY.

         (A) POWERS; DUTIES SPECIFIED. Each Lender irrevocably authorizes each
Agent to take such action on such Lender's behalf and to exercise such powers,
rights and remedies hereunder and under the other Loan Documents as are
specifically delegated or granted to such Agent by the terms hereof and
thereof, together with such powers, rights and remedies as are reasonably
incidental thereto. Each Agent shall have only those duties and
responsibilities that are expressly specified in this Agreement and the other
Loan Documents. Each Agent may exercise such powers, rights and remedies and
perform such duties by or through its agents or employees. No Agent shall
have, by reason of this Agreement or any of the other Loan Documents, a
fiduciary relationship in respect of any Lender; and nothing in this Agreement
or any of the other Loan

                                      97

<PAGE>   106

Documents, expressed or implied, is intended to or shall be so construed as to
impose upon any Agent any obligations in respect of this Agreement or any of
the other Loan Documents except as expressly set forth herein or therein.

         (B) NO RESPONSIBILITY FOR CERTAIN MATTERS. No Agent shall be
responsible to any Lender for the execution, effectiveness, genuineness,
validity, enforceability, collectibility or sufficiency of this Agreement or
any other Loan Document or for any representations, warranties, recitals or
statements made herein or therein or made in any written or oral statements or
in any financial or other statements, instruments, reports or certificates or
any other documents furnished or made by any of Agent to Lenders or by or on
behalf of either Borrower to any Agent or any Lender in connection with the
Loan Documents and the transactions contemplated thereby or for the financial
condition or business affairs of either Borrower or any other Person liable
for the payment of any Obligations, nor shall any Agent be required to
ascertain or inquire as to the performance or observance of any of the terms,
conditions, provisions, covenants or agreements contained in any of the Loan
Documents or as to the use of the proceeds of the Loans or as to the existence
or possible existence of any Event of Default or Potential Event of Default.
Anything contained in this Agreement to the contrary notwithstanding,
Administrative Agent shall not have any liability arising from confirmations
of the amount of outstanding Loans or the component amounts thereof.

         (C) EXCULPATORY PROVISIONS. None of Agents nor any of their
respective officers, partners, directors, employees or agents shall be liable
to Lenders for any action taken or omitted by any Agent under or in connection
with any of the Loan Documents except to the extent caused by such Agent's
gross negligence or willful misconduct. Each Agent shall be entitled to
refrain from any act or the taking of any action (including the failure to
take an action) in connection with this Agreement or any of the other Loan
Documents or from the exercise of any power, discretion or authority vested in
it hereunder or thereunder unless and until such Agent shall have received
instructions in respect thereof from Requisite Lenders (or such other Lenders
as may be required to give such instructions under subsection 9.6) and, upon
receipt of such instructions from Requisite Lenders (or such other Lenders, as
the case may be), such Agent shall be entitled to act or (where so instructed)
refrain from acting, or to exercise such power, discretion or authority, in
accordance with such instructions. Without prejudice to the generality of the
foregoing, (i) each Agent shall be entitled to rely, and shall be fully
protected in relying, upon any communication, instrument or document believed
by it to be genuine and correct and to have been signed or sent by the proper
person or persons, and shall be entitled to rely and shall be protected in
relying on opinions and judgments of attorneys (who may be attorneys for
Borrowers and their Subsidiaries), accountants, experts and other professional
advisors selected by it; and (ii) no Lender shall have any right of action
whatsoever against any Agent as a result of such Agent acting or (where so
instructed) refraining from acting under this Agreement or any of the other
Loan Documents in accordance with the instructions of Requisite Lenders (or
such other Lenders as may be required to give such instructions under
subsection 9.6).

         (D) AGENT ENTITLED TO ACT AS LENDER. The agency hereby created shall
in no way impair or affect any of the rights and powers of, or impose any
duties or obligations upon, any Agent in its individual capacity as a Lender
hereunder. With respect to its participation in the Loans and the Letters of
Credit, each Agent shall have the same rights and powers hereunder as any
other Lender and may exercise the same as though it were not performing the
duties and functions

                                      98

<PAGE>   107


delegated to it hereunder, and the term "Lender" or "Lenders" or any similar
term shall, unless the context clearly otherwise indicates, include each Agent
in its individual capacity. Any Agent and its Affiliates may accept deposits
from, lend money to and generally engage in any kind of banking, trust,
financial advisory or other business with Company or any of its Affiliates as
if it were not performing the duties specified herein, and may accept fees and
other consideration from Borrowers for services in connection with this
Agreement and otherwise without having to account for the same to Lenders.

8.3      REPRESENTATIONS AND WARRANTIES; NO RESPONSIBILITY FOR APPRAISAL OF
         CREDITWORTHINESS.

         Each Lender represents and warrants that it has made its own
independent investigation of the financial condition and affairs of the Loan
Parties in connection with the making of the Loans hereunder and that it has
made and shall continue to make its own appraisal of the creditworthiness of
the Loan Parties. No Agent shall have any duty or responsibility, either
initially or on a continuing basis, to make any such investigation or any such
appraisal on behalf of Lenders or to provide any Lender with any credit or
other information with respect thereto, whether coming into its possession
before the making of the Loans or at any time or times thereafter, and no
Agent shall have any responsibility with respect to the accuracy of or the
completeness of any information provided to Lenders.

8.4      RIGHT TO INDEMNITY.

         Each Lender, in proportion to its Pro Rata Share, severally agrees to
indemnify each Agent, to the extent that such Agent shall not have been
reimbursed by Borrowers, for and against any and all liabilities, obligations,
losses, damages, penalties, actions, judgments, suits, costs, expenses
(including counsel fees and disbursements) or disbursements of any kind or
nature whatsoever which may be imposed on, incurred by or asserted against
such Agent in exercising its powers, rights and remedies or performing its
duties hereunder or under the other Loan Documents or otherwise in its
capacity as such Agent in any way relating to or arising out of this Agreement
or the other Loan Documents; provided that no Lender shall be liable for any
portion of such liabilities, obligations, losses, damages, penalties, actions,
judgments, suits, costs, expenses or disbursements resulting from such Agent's
gross negligence or willful misconduct. If any indemnity furnished to any
Agent for any purpose shall, in the opinion of such Agent, be insufficient or
become impaired, such Agent may call for additional indemnity and cease, or
not commence, to do the acts indemnified against until such additional
indemnity is furnished.

8.5      SUCCESSOR ADMINISTRATIVE AGENT.

         (A) SUCCESSOR ADMINISTRATIVE AGENT. Administrative Agent may resign
at any time by giving 30 days' prior written notice thereof to Lenders and
Borrowers, and Administrative Agent may be removed at any time with or without
cause by an instrument or concurrent instruments in writing delivered to
Borrowers and Administrative Agent and signed by Requisite Lenders. Upon any
such notice of resignation or any such removal, Requisite Lenders shall have
the right, upon five Business Days' notice to Borrowers, to appoint a
successor Administrative Agent, which successor Administrative Agent shall,
unless an Event of Default shall have occurred and be continuing, be subject
to approval of Borrowers (such approval not to be unreasonably

                                      99

<PAGE>   108

withheld or delayed). Upon the acceptance of any appointment as Administrative
Agent hereunder by a successor Administrative Agent, that successor
Administrative Agent shall thereupon succeed to and become vested with all the
rights, powers, privileges and duties of the retiring or removed
Administrative Agent and the retiring or removed Administrative Agent shall be
discharged from its duties and obligations under this Agreement. After any
retiring or removed Administrative Agent's resignation or removal hereunder as
Administrative Agent, the provisions of this Section 8 shall inure to its
benefit as to any actions taken or omitted to be taken by it while it was
Agent under this Agreement.

         (B)      INTENTIONALLY OMITTED.

8.6      COLLATERAL DOCUMENTS AND GUARANTIES.

         Each Lender hereby further authorizes Administrative Agent, on behalf
of and for the benefit of Lenders, to enter into each Collateral Document as
secured party and to be the agent for and representative of Lenders under the
Subsidiary Guaranty, and each Lender agrees to be bound by the terms of each
Collateral Document and the Subsidiary Guaranty; provided that Administrative
Agent shall not (i) enter into or consent to any material amendment,
modification, termination or waiver of any provision contained in any
Collateral Document or the Subsidiary Guaranty or (ii) release any Collateral
(except as otherwise expressly permitted or required pursuant to the terms of
this Agreement or the applicable Collateral Document), in each case without
the prior consent of Requisite Lenders (or, if required pursuant to subsection
9.6, all Lenders); provided further, however, that, without further written
consent or authorization from Lenders, Administrative Agent shall, in
accordance with the terms of this subsection 8.6 and the Loan Documents,
execute any documents or instruments necessary to (a) release any Lien
encumbering any item of Collateral that is the subject of a sale or other
disposition of assets permitted by this Agreement or to which Requisite
Lenders have otherwise consented or (b) release any Subsidiary Guarantor from
the Subsidiary Guaranty if all of the Capital Stock of such Subsidiary
Guarantor is sold to any Person (other than an Affiliate of Company) pursuant
to a sale or other disposition permitted hereunder or to which Requisite
Lenders have otherwise consented. In the event Collateral is sold in an Asset
Sale permitted hereunder or otherwise consented to by Requisite Lenders,
Administrative Agent shall, without further consent or authorization from
Lenders, release the Liens granted under the Collateral Documents on the
Collateral that is the subject of such Asset Sale concurrently with the
consummation of such Asset Sale; provided that Administrative Agent (and its
counsel) shall have received (i) not less than 5 Business Days' prior to the
consummation of such Asset Sale from Company unless a shorter notice period is
agreed to by Administrative Agent, notice of such Asset Sale in the form of an
Officers' Certificate (1) certifying that no Event of Default or Potential
Event of Default shall have occurred and be continuing as of the date of such
release of Collateral, (2) setting forth a detailed description of the
Collateral subject to such Asset Sale, (3) certifying that such Asset Sale is
permitted under this Agreement and that all conditions precedent to such Asset
Sale under this Agreement have been met, (4) attaching UCC-3 release
statements correctly prepared in form and substance reasonably satisfactory to
Administrative Agent for execution by Administrative Agent to release the
Lenders' Lien on the Collateral subject to such Asset Sale and (5) attaching,
if applicable, in the case of an ACSI Network Sale, a true and correct copy of
the ACSI Escrow Agreement; (ii) upon consummation of such Asset Sale, written
notice of the consummation thereof; and (iii) in the case of an Asset Sale
other than an ACSI Asset Sale prior

                                     100

<PAGE>   109

to or simultaneously with the consummation of such Asset Sale, Administrative
Agent shall have received the Officers' Certificate required pursuant to
subsection 2.4B(iii)(f) together with all Net Asset Sale Proceeds of such
Asset Sale, if any, then required to be applied to repay Secured Obligations
under this Agreement. Upon payment in full of all of the Obligations,
Administrative Agent shall release the Liens on such Collateral granted
pursuant to the Collateral Documents. Upon any release of Collateral pursuant
to the foregoing, Administrative Agent shall, at Borrowers' expense, execute
and deliver such documents (without recourse or representation or warranty) as
reasonably requested to evidence such release. Anything contained in any of
the Loan Documents to the contrary notwithstanding, Company, Administrative
Agent and each Lender hereby agree that (1) no Lender shall have any right
individually to realize upon any of the Collateral under any Collateral
Document or to enforce the Subsidiary Guaranty, it being understood and agreed
that all powers, rights and remedies under the Collateral Documents and the
Subsidiary Guaranty may be exercised solely by Administrative Agent for the
benefit of Lenders in accordance with the terms thereof, and (2) in the event
of a foreclosure by Administrative Agent on any of the Collateral pursuant to
a public or private sale, Administrative Agent or any Lender may be the
purchaser of any or all of such Collateral at any such sale and Administrative
Agent, as agent for and representative of Lenders (but not any Lender or
Lenders in its or their respective individual capacities unless Requisite
Lenders shall otherwise agree in writing) shall be entitled, for the purpose
of bidding and making settlement or payment of the purchase price for all or
any portion of the Collateral sold at any such public sale, to use and apply
any of the Obligations as a credit on account of the purchase price for any
Collateral payable by Administrative Agent at such sale.

                                  SECTION 9.
                                MISCELLANEOUS

9.1      ASSIGNMENTS AND PARTICIPATIONS IN LOANS.

         (A) GENERAL. Subject to subsection 9.1B, each Lender shall have the
right at any time to (i) sell, assign or transfer to any Eligible Assignee, or
(ii) sell participations to any Person in, all or any part of any Loan or
Loans made by it or any other interest herein or in any other Obligations owed
to it; provided that no such sale, assignment, transfer or participation
shall, without the consent of Borrowers, require Borrowers to file a
registration statement with the SEC or apply to qualify such sale, assignment,
transfer or participation under the securities laws of any state; provided
further that no such sale, assignment or transfer described in clause (i)
above shall be effective unless and until an Assignment Agreement effecting
such sale, assignment or transfer shall have been accepted by Administrative
Agent and recorded in the Register as provided in subsection 9.1B(ii). Except
as otherwise provided in this subsection 9.1, no Lender shall, as between
Borrowers and such Lender, be relieved of any of its obligations hereunder as
a result of any sale, assignment or transfer of, or any granting of
participations in, all or any part of its Loans, or the other Obligations owed
to such Lender.

         (B) ASSIGNMENTS.

                  (i)      Amounts and Terms of Assignments.  Each Loan or
         other Obligation may (a) be assigned in any amount to another Lender,
         or to an Affiliate of the assigning Lender or another Lender, with
         the giving of notice to Borrowers and Administrative

                                     101

<PAGE>   110

         Agent or (b) be assigned in an aggregate amount of not less than
         $1,000,000 in the case of the Series A Revolving Loans and $1,000,000
         in the case of the Series B Term Loans and the Series C Term Loans
         (in each case, other than for assignments to other Lenders or
         Affiliates of such Lender or other Lenders) (or such lesser amount as
         shall constitute the aggregate amount of the Loans and other
         Obligations of the assigning Lender) to any other Eligible Assignee
         with the giving of notice to Borrowers and with the consent of
         Company (except with respect to any assignment under the Loan Put
         Agreement or upon the occurrence and during the continuance of an
         Event of Default) and Administrative Agent (which consent of Company
         and Administrative Agent shall not be unreasonably withheld or
         delayed).  To the extent of any such assignment in accordance with
         either clause (a) or (b) above, the assigning Lender shall be
         relieved of its obligations with respect to its Loans or other
         Obligations or the portion thereof so assigned.  The parties to each
         such assignment shall execute and deliver to Administrative Agent,
         for its acceptance and recording in the Register, an Assignment
         Agreement, together with a processing and recordation fee of $3,500
         with respect to assignments by any Lender (other than GSCP) to any
         person and $500 with respect to assignments by or to GSCP, and such
         forms, certificates or other evidence, if any, with respect to United
         States federal income tax withholding matters as the assignee under
         such Assignment Agreement may be required to deliver to
         Administrative Agent pursuant to subsection 2.7B(iii)(a).  Upon such
         execution, delivery, acceptance and recordation, from and after the
         effective date specified in such Assignment Agreement, (1) the
         assignee thereunder shall be a party hereto and, to the extent that
         rights and obligations hereunder have been assigned to it pursuant to
         such Assignment Agreement, shall have the rights and obligations of a
         Lender hereunder and (2) the assigning Lender thereunder shall, to
         the extent that rights and obligations hereunder have been assigned
         by it pursuant to such Assignment Agreement, relinquish its rights
         (other than any rights which survive the termination of this
         Agreement under subsection 9.8B) and be released from its obligations
         under this Agreement (and, in the case of an Assignment Agreement
         covering all or the remaining portion of an assigning Lender's rights
         and obligations under this Agreement, such Lender shall cease to be a
         party hereto.  If any such assignment occurs after the issuance of
         any Notes hereunder, the assigning Lender shall, upon the
         effectiveness of such assignment or as promptly thereafter as
         practicable, surrender its applicable Notes to Administrative Agent
         for cancellation, and thereupon, upon the request of the assignee
         and/or the assigning Lender, new Notes shall be issued to the
         assignee and/or to the assigning Lender, substantially in the form of
         Exhibit IV, Exhibit V or Exhibit VI annexed hereto, as the case may
         be, with appropriate insertions, to reflect the new Loans of the
         assignee and/or the assigning Lender.

                  (ii)     Acceptance by Administrative Agent; Recordation in
         Register.  Upon its receipt of an Assignment Agreement executed by an
         assigning Lender and an assignee representing that it is an Eligible
         Assignee, together with the processing and recordation fee referred
         to in subsection 9.1B(i) and any forms, certificates or other
         evidence with respect to United States federal income tax withholding
         matters that such assignee may be required to deliver to
         Administrative Agent pursuant to subsection 2.7B(iii)(a),
         Administrative Agent shall, if Administrative Agent and Company have
         consented to the assignment evidenced thereby (in each case to the

         accept such Assignment Agreement by executing a

         counterpart thereof as provided therein (which acceptance shall
         evidence any required consent of Administrative Agent to such
         assignment), (b) record the information contained therein in the
         Register, and (c) give prompt notice thereof to Company.

         Loan Put Agreement shall be permitted assignments hereunder.

         (C) PARTICIPATIONS. The holder of any participation, other than an
Affiliate of the Lender granting such participation, shall not be entitled to
require such Lender to take or omit to take any action hereunder except action
directly affecting (i) the extension of the regularly scheduled maturity of
any portion of the principal amount of or interest on any Loan allocated to
such participation or (ii) a reduction of the principal amount of or the rate
of interest payable on any Loan allocated to such participation, and all
amounts payable by Company hereunder (including amounts payable to such Lender
pursuant to subsections 2.6D and 2.7) shall be determined as if such Lender
had not sold such participation. Company and each Lender hereby acknowledge
and agree that, solely for purposes of subsections 9.4 and 9.5, (a) any
participation will give rise to a direct obligation of Company to the
participant and (b) the participant shall be considered to be a "Lender".

         (D) ASSIGNMENTS TO FEDERAL RESERVE BANKS. In addition to the
assignments and participations permitted under the foregoing provisions of
this subsection 9.1, any Lender may assign and pledge all or any portion of

Federal Reserve Bank as collateral security pursuant to Regulation A of the
Board of Governors of the Federal Reserve System and any operating circular
issued by such Federal Reserve Bank or (ii) to a trustee in connection with a
Loan securitization transaction; provided that (i) no Lender shall, as between
Borrowers and such Lender, be relieved of any of its obligations hereunder as
a result of any such assignment and pledge and (ii) in no event shall any
Federal Reserve Bank be considered to be a "Lender" or be entitled to require
the assigning Lender to take or omit to take any action hereunder.

         (E) INFORMATION. Each Lender may furnish any information concerning
the Loan Parties in the possession of that Lender from time to time to
assignees and participants (including prospective assignees and participants),
subject to subsection 9.18.

         (F) REPRESENTATIONS OF LENDERS. Each Lender listed on the signature
pages hereof hereby represents and warrants (i) that it is an Eligible
Assignee described in clause (i) of the definition thereof; (ii) that it has
experience and expertise in the making of or investing in loans such as the
Loans; and (iii) that it will make its Loans for its own account in the
ordinary course of its business and without a view to distribution of such
Loans within the meaning of the Securities Act or the Exchange Act or other
federal securities laws (it being understood that, subject to the provisions
of this subsection 9.1, the disposition of such Loans or any interests therein
shall at all times remain within its exclusive control). Each Lender that
becomes a party hereto pursuant to an Assignment Agreement shall be deemed to
agree that the representations

                                     103

and warranties of such Lender contained in Section 2(c) of such Assignment

9.3      INDEMNITY.

         In addition to the payment of expenses pursuant to subsection 9.2,
whether or not the transactions contemplated hereby shall be consummated,
Borrowers agree, jointly and severally, to defend (subject to Indemnitees'
selection of counsel), indemnify, pay and hold harmless Agents and Lenders,
and the officers, partners, directors, employees, agents and affiliates of any
of Agents and Lenders (collectively called the "INDEMNITEES"), from and
against any and all Indemnified Liabilities (as hereinafter defined); provided
that neither Borrower shall have any obligation to any Indemnitee hereunder
with respect to any Indemnified Liabilities to the extent such Indemnified
Liabilities arise solely from the gross negligence or willful misconduct of
that Indemnitee as determined by a final, non-appealable judgment of a court
of competent jurisdiction.

         As used herein, "INDEMNIFIED LIABILITIES" means, collectively, any
and all liabilities, obligations, losses, damages (including natural resource
damages), penalties, actions, judgments, suits, claims (including
Environmental Claims), costs (including the costs of any investigation, study,
sampling, testing, abatement, cleanup, removal, remediation or other response
action necessary to remove, remediate, clean up or abate any Hazardous
Materials Activity), expenses and disbursements of any kind or nature
whatsoever (including the reasonable fees and disbursements of counsel for
Indemnitees in connection with any investigative, administrative or judicial
proceeding commenced or threatened by any Person, whether or not any such
Indemnitee shall be designated as a party or a potential party thereto, and
any fees or expenses incurred by Indemnitees in enforcing this indemnity),
whether direct, indirect or consequential and whether based on any federal,
state or foreign laws, statutes, rules or regulations (including securities
and commercial laws, statutes, rules or regulations and Environmental Laws),
on common law or equitable cause or on contract or otherwise, that may be
imposed on, incurred by, or asserted against any such Indemnitee, in any
manner relating to or arising out of (i) this Agreement or the other Loan
Documents or the transactions contemplated hereby or thereby (including
Lenders' agreement to make the Loans hereunder or the use or intended use of
the proceeds thereof, or any enforcement of any of the Loan Documents
(including any sale of, collection from, or other realization upon any of the
Collateral or the enforcement of the Subsidiary Guaranty)), (ii) the
statements contained in the commitment letter delivered by any Lender to
Company with respect thereto, or (iii) any Environmental Claim or any
Hazardous Materials Activity relating to or arising from, directly or
indirectly, any past or present activity, operation, land ownership, or
practice of Company or any of its Subsidiaries.

         To the extent that the undertakings to defend, indemnify, pay and
hold harmless set forth in this subsection 9.3 may be unenforceable in whole
or in part because they are violative of any law or public policy, Borrowers
shall contribute the maximum portion that it is permitted to pay and satisfy
under applicable law to the payment and satisfaction of all Indemnified
Liabilities incurred by Indemnitees or any of them.

9.4      SET-OFF; SECURITY INTEREST IN DEPOSIT ACCOUNTS.

         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 of
any Event of Default each Lender is hereby authorized by Borrowers at any time
or from time to time, without notice to Borrowers or to any

                                     105

<PAGE>   114

other Person, any such notice being hereby expressly waived, to set off and to
appropriate and to apply any and all deposits (general or special, including
Indebtedness evidenced by certificates of deposit, whether matured or
unmatured, but not including trust accounts) and any other Indebtedness at any
time held or owing by that Lender to or for the credit or the account of such
Borrower against and on account of the obligations and liabilities of such
Borrower to that Lender under this Agreement and the other Loan Documents,
including all claims of any nature or description arising out of or connected
with this Agreement or any other Loan Document, irrespective of whether or not
(i) that Lender shall have made any demand hereunder or (ii) the principal of
or the interest on the Loans or any other amounts due hereunder shall have
become due and payable pursuant to Section 7 and although said obligations and
liabilities, or any of them, may be contingent or unmatured. Borrowers hereby
further grant to Administrative Agent and each Lender a security interest in
all deposits and accounts maintained with Administrative Agent or such Lender
as security for the Obligations.

9.5      RATABLE SHARING.

         Lenders hereby agree among themselves that if any of them shall,
whether by voluntary payment (other than a voluntary prepayment of Loans made
and applied in accordance with the terms of this Agreement), by realization
upon security, through the exercise of any right of set-off or banker's lien,
by counterclaim or cross action or by the enforcement of any right under the
Loan Documents or otherwise, or as adequate protection of a deposit treated as
cash collateral under the Bankruptcy Code, receive payment or reduction of a
proportion of the aggregate amount of principal, interest, fees and other
amounts then due and owing to that Lender hereunder or under the other Loan
Documents (collectively, the "AGGREGATE AMOUNTS DUE" to such Lender) which is
greater than the proportion received by any other Lender in respect of the
Aggregate Amounts Due to such other Lender, then the Lender receiving such
proportionately greater payment shall (i) notify Administrative Agent and each
other Lender of the receipt of such payment and (ii) apply a portion of such
payment to purchase participations (which it shall be deemed to have purchased
from each seller of a participation simultaneously upon the receipt by such
seller of its portion of such payment) in the Aggregate Amounts Due to the
other Lenders so that all such recoveries of Aggregate Amounts Due shall be
shared by all Lenders in proportion to the Aggregate Amounts Due to them;
provided that if all or part of such proportionately greater payment received
by such purchasing Lender is thereafter recovered from such Lender upon the
bankruptcy or reorganization of either Borrower or otherwise, those purchases
shall be rescinded and the purchase prices paid for such participations shall
be returned to such purchasing Lender ratably to the extent of such recovery,
but without interest. Borrowers expressly consent to the foregoing arrangement
and agrees that any holder of a participation so purchased may exercise any
and all rights of banker's lien, set-off or counterclaim with respect to any
and all monies owing by Borrowers to that holder with respect thereto as fully
as if that holder were owed the amount of the participation held by that
holder.

9.6      AMENDMENTS AND WAIVERS.

         No amendment, modification, termination or waiver of any provision of
the Loan Documents, or consent to any departure by Loan Parties therefrom,
shall in any event be effective without the written concurrence of Requisite
Lenders; provided that no such amendment, modification, termination, waiver or
consent shall, without the consent of each

                                     106

<PAGE>   115

Lender (with Obligations directly affected in the case of the following clause
(i)): (i) extend the scheduled final maturity of any Loan or Note or waive,
reduce or postpone any scheduled repayments of the Loans pursuant to
subsection 2.4A or reduce the rate of interest on any Loan (other than any
waiver of any increase in the interest rate applicable to any Loan pursuant to
subsection 2.2E) or any commitment fees payable hereunder, or extend the time
for payment of any such interest or fees, or reduce the principal amount of
any Loan or (ii) amend, modify, terminate or waive any provision of subsection
2.4D(iii), subsection 9.5 or this subsection 9.6, (iii) reduce the percentage
specified in the definition of "Requisite Lenders", (iv) consent to the
assignment or transfer by either Borrower of any of its rights and obligations
under this Agreement or (v) release all or substantially all of the Collateral
or all or substantially all of the Subsidiary Guarantors from the Subsidiary
Guaranty except as expressly provided in the Loan Documents; provided, further
that no such amendment, modification, termination or waiver shall amend,
modify, terminate or waive any provision of Section 8 as the same applies to
any Agent, or any other provision of this Agreement as the same applies to the
rights or obligations of any Agent, in each case without the consent of such
Agent, and provided further that, subject to the agreement of the Lenders not
to take certain actions without the consent of the Huff Fund in Section 7 of
the Loan Put Agreement, neither the Huff Fund nor any Affiliate of the Huff
Fund shall have any voting rights under this subsection 9.6 or otherwise under
the Loan Documents in respect of the Assigned Loans (as defined in the Loan
Put Agreement) including in any bankruptcy proceedings. The immediately
preceding proviso shall terminate with respect to Loans that are duly assigned
pursuant to subsection 9.1 to a Person that is not an Affiliate of the Huff
Fund. Administrative Agent may, but shall have no obligation to, with the
concurrence of any Lender, execute amendments, modifications, waivers or
consents on behalf of that Lender. Any waiver or consent shall be effective
only in the specific instance and for the specific purpose for which it was
given. No notice to or demand on Borrowers in any case shall entitle Borrowers
to any other or further notice or demand in similar or other circumstances.
Any amendment, modification, termination, waiver or consent effected in
accordance with this subsection 9.6 shall be binding upon each Lender at the
time outstanding, each future Lender and, if signed by Borrowers, on
Borrowers.

8.4 and 9.5 shall survive the payment of the Loans and the termination of this
Agreement.

9.9      FAILURE OR INDULGENCE NOT WAIVER; REMEDIES CUMULATIVE.

         No failure or delay on the part of Administrative Agent or any Lender
in the exercise of any power, right or privilege hereunder or under any other
Loan Document shall impair such power, right or privilege or be construed to
be a waiver of any default or acquiescence therein, nor shall any single or
partial exercise of any such power, right or privilege preclude other or
further exercise thereof or of any other power, right or privilege. All rights
and remedies existing under this Agreement and the other Loan Documents are
cumulative to, and not exclusive of, any rights or remedies otherwise
available.

9.10     MARSHALLING; PAYMENTS SET ASIDE.

         Neither Administrative Agent nor any Lender shall be under any
obligation to marshal any assets in favor of Company or any other party or
against or in payment of any or all of the Obligations. To the extent that
either Borrower makes a payment or payments to Administrative Agent or Lenders
(or to Administrative Agent for the benefit of Lenders), or Administrative
Agent or Lenders enforce any security interests or exercise their rights of
setoff, and such payment or payments or the proceeds of such enforcement or
setoff or any part thereof are subsequently invalidated, declared to be
fraudulent or preferential, set aside and/or required to be repaid to a
trustee, receiver or any other party under any bankruptcy law, any other state
or federal law, common law or any equitable cause, then, to the extent of such
recovery, the obligation or part thereof originally intended to be satisfied,

effect as if such payment or payments had not been made or such enforcement or
setoff had not occurred.

9.11     SEVERABILITY.

         In case any provision in or obligation under this Agreement or the
Notes shall be invalid, illegal or unenforceable in any jurisdiction, the
validity, legality and enforceability of the remaining provisions or
obligations, or of such provision or obligation in any other jurisdiction,
shall not in any way be affected or impaired thereby.

9.12     OBLIGATIONS SEVERAL; INDEPENDENT NATURE OF LENDERS' RIGHTS.

         The obligations of Lenders hereunder are several and no Lender shall
be responsible for the obligations of any other Lender hereunder. Nothing
contained herein or in any other Loan Document, and no action taken by Lenders
pursuant hereto or thereto, shall be deemed to constitute Lenders as a
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, and each Lender shall be entitled to protect and enforce its
rights arising out of this Agreement and it shall not be necessary for any
other Lender to be joined as an additional party in any proceeding for such
purpose.

RESPECTIVE RIGHTS TO A JURY TRIAL OF ANY CLAIM OR CAUSE OF ACTION BASED UPON
OR ARISING OUT OF THIS AGREEMENT OR ANY OF THE OTHER LOAN DOCUMENTS OR ANY
DEALINGS BETWEEN THEM RELATING TO THE SUBJECT MATTER OF THIS LOAN TRANSACTION

9.18     CONFIDENTIALITY.

         Each Lender shall hold all non-public information obtained pursuant
to the requirements of this Agreement which has been identified as
confidential by Borrowers in accordance with such Lender's customary
procedures for handling confidential information of this nature and in
accordance with prudent lending or investing practices, it being understood
and agreed by Borrowers that in any event a Lender may make disclosures to
Affiliates of such Lender or disclosures reasonably required by any bona fide
assignee, transferee or participant in connection with the contemplated
assignment or transfer by such Lender of any Loans or any participations
therein (it being understood that the Persons to whom such disclosure is made
will be informed of the confidential nature of such information and will have
agreed to keep such information confidential) or disclosures required by any
governmental agency or representative thereof or by the National Association
of Insurance Commissioners or pursuant to legal process; provided that, unless
specifically prohibited by applicable law or court order, each Lender shall
notify Borrowers of any request by any governmental agency or representative
thereof (other than any such request in connection with any examination of the
financial condition of such Lender by such governmental agency) for disclosure
of any such non-public information prior to disclosure of such information;
and provided, further that in no event shall any Lender be obligated or
required to return any materials furnished by Company or any of its
Subsidiaries.

9.19     MAXIMUM AMOUNT.

         (A) It is the intention of Borrowers and Lenders to conform strictly
to the usury and similar laws relating to interest from time to time in force,
and all agreements between Borrowers, Administrative Agent and Lenders,
whether now existing or hereafter arising and whether oral or written, are
hereby expressly limited so that in no contingency or event whatsoever,
whether by acceleration of maturity hereof or otherwise, shall the amount paid
or agreed to be paid in the aggregate to Lenders or to Administrative Agent on
behalf of Lenders as interest hereunder or under the other Loan Documents or
in any other security agreement given to secure the Obligations, or in any
other document evidencing, securing or pertaining to the indebtedness
evidenced hereby or thereby, exceed the maximum amount permissible under
applicable usury or such other laws (the "MAXIMUM AMOUNT"). If under any
circumstances whatsoever fulfillment of any provision hereof, or of any of the
other Loan Documents, at the time performance of such provision shall be due,
shall involve exceeding the Maximum Amount, then, ipso facto, the obligation
to be fulfilled shall be reduced to the Maximum Amount. For the purposes of
calculating the actual amount of interest paid and/or payable hereunder in
respect of laws pertaining to usury or such other laws, all sums paid or
agreed to be paid to Lenders for the use, forbearance or detention of the
indebtedness of Company evidenced hereby, outstanding from time to time shall,
to the extent permitted by applicable law, be amortized, pro rated, allocated
and spread from the date of disbursement of the proceeds of the Loans until
payment in full of all of such indebtedness, so that the actual rate of
interest on account of such indebtedness is uniform throughout the term
hereof. The terms and provisions of this subsection shall control and
supersede every other provision of all agreements between Company,
Administrative Agent and Lenders.

                                     111

<PAGE>   120

         (B) If under any circumstances Lenders shall receive an amount which
would exceed the Maximum Amount, such amount shall be deemed a payment in
reduction of the principal amount of the Loans and shall be treated as a
voluntary prepayment under subsection 2.4B(i), and shall be so applied in
accordance with subsection 2.4B(iv) hereof, or if such amount exceeds the
unpaid balance of the Loans and any other indebtedness of Company in favor of
Lenders, the excess shall be deemed to have been a payment made by mistake and
shall be refunded to Company.

9.20     ENTIRE AGREEMENT.

         This Agreement, together with the other Loan Documents and other
documents delivered pursuant hereto and thereto, represent the entire
agreement among the parties hereto with respect to the subject matter hereof
and supersede all prior agreements and understandings of the parties relating
to the subject matter hereof.

9.21     COUNTERPARTS; EFFECTIVENESS.

         This Agreement and any amendments, waivers, consents or supplements
hereto or in connection herewith may be executed in any number of counterparts
and by different parties hereto in separate counterparts, each of which when
so executed and delivered shall be deemed an original, but all such
counterparts together shall constitute but one and the same instrument;
signature pages may be detached from multiple separate counterparts and
attached to a single counterpart so that all signature pages are physically
attached to the same document. This Agreement shall become effective upon the
execution of a counterpart hereof by each of the parties hereto and receipt by
Company and Administrative Agent of written or telephonic notification of such
execution and authorization of delivery thereof.

9.22     ACKNOWLEDGMENT AND CONSENT.

         Each Loan Party hereby acknowledges that it has reviewed the terms
and provisions of this Agreement. Each Loan Party hereby confirms that each
Loan Document to which it is a party or otherwise bound and all Collateral
encumbered thereby will continue to guaranty or secure, as the case may be, to
the fullest extent possible the payment and performance of all "Guarantied
Obligations" and "Secured Obligations" as the case may be (in each case as

         Each of the Loan Parties hereby, to the fullest extent permitted by
applicable law, acknowledges and confirms that it does not have any grounds
and hereby agrees not to challenge (or to allege or to pursue any matter,
cause or claim arising under or with respect to) the Original Credit
Agreement, this Agreement or any of the other Loan Documents, any of the terms
or conditions thereof or thereunder, or the status of any thereof as legal,
valid and binding obligations enforceable in accordance with their respective
terms; and it does not possess (and hereby forever waives, remises, releases,
discharges and holds harmless the Lenders and the Agents, and their respective
affiliates, stockholders, directors, officers, employees, attorneys, agents
and representatives and each of their respective heirs, executors,
administrators, successors and assigns (collectively, the "INDEMNIFIED
PARTIES") from and against, and agrees not to allege or pursue) any action,
cause of action, suit, debt, claim, counterclaim, cross-claim, demand,
defense, offset, opposition, demand and other right of action whatsoever,
whether in law, equity or otherwise (which it, all those claiming by, through
or under it, or its successors or assigns, have or may have) against the
Indemnified Parties, or any of them, prior to or as of the Restatement
Effective Date for, upon, or by reason of, any matter, cause or thing
whatsoever, arising out of, or relating to the Original Credit Agreement, this
Agreement or any of the other Loan Documents (including, without limitation,
any payment, performance, validity or enforceability of any or all of the
terms or conditions thereof or thereunder) or any transaction relating to any
of the foregoing, or any or all actions, courses of conduct or other matters
in any manner whatsoever relating to or otherwise connected with any of the
foregoing.
