date and (ii) at the time any purchase of participations pursuant to this
sentence is actually made, the purchasing Lender shall be required to pay the
Swingline Bank interest on the principal amount of the participation purchased
for each day from and including the day upon which the Mandatory Borrowing would
otherwise have occurred to but excluding the date of payment for such

larger integral multiple of $100,000 in excess thereof.  If any notice of
prepayment is given, the principal amount stated therein, together with accrued
interest on the amount of LIBOR Advances prepaid and the amount, if any, due
under Section 2.12 and Section 2.14 hereof, shall be due and payable on the date

                                      35

specified in such notice unless the Borrower revokes its notice, provided that,
                                                                 -------------
if the Borrower revokes its notice of prepayment prior to such date specified,
the Borrower shall reimburse the Administrative Agent for the account of all
Lenders for all Consequential Losses suffered by each Lender as a result of the
Borrower's failure to prepay.  A certificate of each Lender claiming
compensation under this Section 2.04(a), setting forth in reasonable detail the
calculation of the additional amount or amounts to be paid to it hereunder shall
be presumptive evidence of the validity of such claim.

     (b) The application of prepayments made under this Section 2.04 as between
the Swingline Loan, the Revolver A Loan, the Revolver B Loan and the Working
Line Loan shall be determined in accordance with the provisions of Section
2.13(f) hereof.  All prepayments made pursuant to this Section 2.04 (other than
to the Swingline Loan) shall be first applied to Base Advances then to LIBOR
Advances, all without premium or penalty, except the Borrower must pay together
with any such prepayments, any Consequential Losses. After (i) the Conversion
Date, and (ii) the Option Date (if the Borrower and the SuperMajority Lenders
did not agree to an Extension Option), Working Line Advances prepaid hereunder
may not be reborrowed.

     2.05.  Mandatory Prepayments.

     (a) Asset Sales and Investments.  To the extent that the Borrower or any of
the Restricted Subsidiaries consummates any Disposition of any asset or any of
its Properties except (i) Dispositions consummated in accordance with the terms
of Section 8.05(a)(i) hereof and (ii) if there exists no Default or Event of
Default both before and after giving effect to any such Disposition,
Dispositions consummated in accordance with the other terms and provisions of
Section 8.05(a) hereof (other than Section 8.05(a)(i) hereof), then the Borrower
shall immediately use or cause to be used 100% of the Net Proceeds of any such
transaction received by or allocated to the Borrower or such Restricted
Subsidiary as the case may be, to repay the Obligations under the Loans except
to the extent that such Net Proceeds are ultimately reinvested within a 12 month
period after any such asset Disposition, in assets used in the
Telecommunications Business, including, without limitation, the internet,
internet protocol, web hosting or electronic commerce of the Borrower or any of
the Wholly Owned Restricted Subsidiaries, acquisitions permitted under Section
8.18 hereof or Investments permitted under Section 8.04 hereof.

     (b) Mandatory Prepayments, Generally.  The application of prepayments made
under this Section 2.05 as between the Swingline Loan, the Revolver A Loan, the
Revolver B Loan and the Working Line Loan shall be determined in accordance with
the provisions of Section 2.13(f) hereof.  All prepayments made pursuant to this
Section 2.05 (other than to the Swingline Loan) shall be first applied to Base
Advances then to LIBOR Advances, all without premium or penalty, except the
Borrower must pay together with such prepayments, any accrued interest on LIBOR
Advances repaid by such prepayments and any Consequential Losses.  After (i) the
Conversion Date, and (ii) the Option Date (if the Borrower and the SuperMajority
Lenders did not agree to an Extension Option), Working Line Advances prepaid
hereunder may not be reborrowed.

     2.06.  Repayment.

     (a) LIBOR Advances.  The principal amount of each LIBOR Advance is due and
payable on the last day of the applicable Interest Period, which principal
payment may be made by means of a Refinancing Advance in accordance with the
terms of Section 2.09 hereof (and subject to the other provisions of this
Agreement).

                                      36
<PAGE>

     (b) Commitment Reduction.  On the date of a reduction of any of the
Commitments pursuant to Section 2.11 hereof, the aggregate amount of outstanding
(i) Revolver A Advances in excess of the Revolver A Commitment as reduced, (ii)
Revolver B Advances in excess of the Revolver B Commitment as reduced, and (iii)
prior to the Conversion Date, Working Line Advances in excess of the Working
Line Commitment shall in each case be immediately due and payable.  Each such
principal repayments may not be made by means of Refinancing Advances.

     (c) Option Date and Extension Final Maturity.  The aggregate outstanding
amount of the Working Line Advances shall be due and payable in full on the
Option Date, provided that, notwithstanding the foregoing, on the Option Date if
             -------------
the Borrower and the SuperMajority Lenders have agreed to an Extension Option in
accordance with the terms of Section 2.16 hereof, then such extended portion of
the Working Line Loan shall be due and payable in full on the Extension Final
Maturity.  Any portion of the Working Line Loan not extended in accordance with
the terms of Section 2.16(a) hereof shall be due and payable on the Option Date.

     (d) Conversion Date.  If the Borrower and the Lenders have agreed to an
Extension Option, the aggregate outstanding amount of the Working Line Advances
shall be due and payable in full on the Extension Final Maturity, provided that,
                                                                  -------------
notwithstanding the foregoing, on the Extension Final Maturity, if the Borrower
and the Lenders have agreed to a Conversion Option, then the Working Line Loan
shall be due and payable in full on the Maturity Date.

     (e) Maturity Date.  All outstanding Advances under the Loans (other than
the Working Line Loan) and all other Obligations shall be due and payable in
full on the Maturity Date.

     (f) Repayments, Generally.  All outstanding Advances (other than Advances
under the Working Line Loan) and other Obligations shall be due and payable in
full on the Maturity Date.  Any repayments made pursuant to this Section shall
be without premium or penalty, except the Borrower must pay together with any
such prepayments, any Consequential Losses.  The application of all repayments
as between Loans under this Section 2.06 shall be determined in accordance with
the terms of Section 2.13(f).  Except for the Swingline Loan, repayment of
Advances shall be applied to Base Advances first, and then to LIBOR Advances.
After (i) the Conversion Date, and (ii) the Option Date (if the Borrower and the
SuperMajority Lenders did not agree to an Extension Option), Working Line
Advances prepaid hereunder may not be reborrowed.

     2.07.  Interest.

     (a) Revolver A Advances, Working Line Advances and Revolver B Advances.
Subject to Section 2.08 and Section 11.08 hereof, the Borrower shall pay
interest on the unpaid principal amount of each Advance except Swingline
Advances from the date of such Advance until such principal shall be paid in
full, at either the Base Rate or the LIBOR Rate, as set forth in subsection (i)
or (ii) below, as selected by the Borrower in accordance with Section 2.02
hereof and as follows:

          (i) Base Advances.  Base Advances shall bear interest at a rate per
     annum equal to the Base Rate as in effect from time to time.  If the amount
     of interest payable in respect of any interest computation period is
     reduced to the Highest Lawful Rate and the amount of interest payable in
     respect of any subsequent interest computation period would be less than
     the Maximum Amount, then the amount of interest payable in respect of such
     subsequent

                                      37
<PAGE>

     interest computation period shall be automatically increased to
     the Maximum Amount; provided that at no time shall the aggregate amount by
                         -------------
     which interest paid has been increased pursuant to this sentence exceed the
     aggregate amount by which interest has been reduced pursuant to this
     sentence.

          (ii) LIBOR Advances.  LIBOR Advances shall bear interest at the rate
     per annum equal to the LIBOR Rate applicable to such Advance.

          (iii)  Payment Dates.  Accrued and unpaid interest on Base Advances
     shall be paid quarterly in arrears on each Quarterly Date and on the
     Maturity Date.  Accrued and unpaid interest in respect of each LIBOR
     Advance shall be paid on the last day of the appropriate Interest Period,
     on the Maturity Date and on the date of any prepayment or repayment of such
     Advance; provided, however, that if any Interest Period for a LIBOR Advance
              --------  -------
     exceeds three months, interest shall also be paid on the date which falls
     three months after the beginning of such Interest Period and each three
     months thereafter until such Interest Period expires.

     (b) Swingline Advances.  The Borrower shall pay interest on the outstanding
principal amount of such Swingline Advance, from the date such Swingline Advance
is made until it is due (whether at maturity, by reason of acceleration or
otherwise) and repaid, at an interest rate per annum equal to a fixed money
market interest rate (plus the Applicable Margin for LIBOR Advances) quoted by
the Swingline Bank and agreed to by the Borrower for such Swingline Advance, but
in no event higher than the Highest Lawful Rate.   Accrued and unpaid interest
on Swingline Advances shall be paid quarterly in arrears on each Quarterly Date
and on the Maturity Date.

     2.08.  Default Interest.  During the continuation of any Event of
Default, the Borrower shall pay, on demand, interest (after as well as before
judgment to the extent permitted by Law) on the principal amount of all Advances
outstanding and on all other Obligations due and unpaid hereunder at a per annum
rate equal to (a) until, for each LIBOR Advance in existence at such time, the
expiration of the applicable Interest Period relating to such LIBOR Advance, the
lesser of (i) the Highest Lawful Rate and (ii) the applicable LIBOR Rate for
such LIBOR Advance plus 2% and (b) for each Base Advance, the lesser of the (i)
the Highest Lawful Rate and (ii) the Base Rate plus 2%.  LIBOR Advances shall
not be available for selection by the Borrower during the continuance of an
Event of Default.

     2.09.  Continuation and Conversion Elections.

     (a) The Borrower may upon irrevocable written notice to Administrative
Agent and subject to the terms of this Agreement:

               (i) elect to convert, on any Business Day, all or any portion of
     outstanding Advances which are Base Advances (in an aggregate amount not
     less than $500,000 or an integral multiple of $100,000 in excess thereof)
     into LIBOR Advances; or

               (ii) elect to convert at the end of any Interest Period therefor,
     all or any portion of outstanding Advances which are LIBOR Advances
     comprised in the same Borrowing (in an aggregate amount not less than
     $100,000 or an integral multiple of $50,000 in excess thereof) into Base
     Advances; or

                                      38
<PAGE>

               (iii)  elect to continue, at the end of any Interest Period
     therefor, any Advances which are LIBOR Advances;

provided, however, that if the aggregate amount of outstanding LIBOR Advances
--------  -------
comprised in the same Borrowing shall have been reduced as a result of any
payment, prepayment or conversion of part thereof to an amount less than
$500,000, the LIBOR Advances comprised in such Borrowing shall automatically
convert into Base Advances at the end of each respective Interest Period.

     (b) The Borrower shall deliver a notice of conversion or continuation (a
"Conversion or Continuation Notice"), in substantially the form of Exhibit G
                                                                   ---------
hereto, to Administrative Agent not later than (i) 12:00 p.m. central standard
time three Business Days prior to the proposed date of conversion or
continuation, if the Advances (or any portion of either thereof) are to be
converted into or continued as LIBOR Advances; and (ii) 12:00 p.m. central
standard time on the Business Day of the proposed conversion, if the Advances
(or any portion thereof) are to be converted into Base Advances.

     Each such Conversion or Continuation Notice shall be by telecopy or
telephone, promptly confirmed by letter, specifying therein:

               (i) the proposed date of conversion or continuation;

               (ii) the aggregate amount of Advances to be converted or
     continued, and whether the Advances are Revolver A Advances, Revolver B
     Advances or Working Line Advances;

               (iii)  the nature of the proposed conversion or continuation; and

               (iv) the duration of the applicable Interest Period.

     (c) If, upon the expiration of any Interest Period applicable to LIBOR
Advances, the Borrower shall have failed to select a new Interest Period to be
applicable to such LIBOR Advances or if an Event of Default shall then have
occurred and be continuing, the Borrower shall be deemed to have elected to
convert such LIBOR Advances into Base Advances effective as of the expiration
date of such current Interest Period.

     (d) Notwithstanding any other provision contained in this Agreement, after
giving effect to any conversion or continuation of any Advances, there shall not
be outstanding Advances with more than seven different Interest Periods.

     2.10.  Fees.

     (a)  Commitment Fees.

          (i) Revolver A Commitment Fee.  Subject to Section 11.08 hereof, the
     Borrower shall pay to Administrative Agent for the account of Lenders pro
     rata in accordance with each Lender's Revolver A Specified Percentage, a

     Commitment Fee").

          (ii) Working Line Commitment Fee.  Subject to Section 11.08 hereof,
     the Borrower shall pay to Administrative Agent for the account of Lenders

     Fee Percentage per annum on the average daily amount of the difference
     between the Working Line Commitment and the sum of all outstanding Working
     Line Advances (the "Working Line Commitment Fee").

          (iii)  Revolver B Commitment Fee.  Subject to Section 11.08 hereof,
     the Borrower shall pay to Administrative Agent for the account of Lenders

          (iv) Commitment Fees, Generally.  Each Commitment Fee set forth in
     subsections (i) through (iii) above shall be payable in arrears on each

     2.11.  Reduction of Commitments.

     (a) Mandatory Termination of the Revolver A Commitment and the Revolver B
Commitment.  The Revolver A Commitment and the Revolver B Commitment shall both
automatically be reduced to zero and terminate on the Maturity Date.

     (b) Mandatory Reduction of Commitment Due to Asset Sales.  The Commitment
shall be reduced immediately and automatically in an amount equal to any amount
that would be required by Section 2.05(a) hereof to prepay the Loans (regardless
of whether there are any outstanding Obligations under the Loans)  as a result
of any Dispositions of assets and Properties of the Borrower or any of the
Restricted Subsidiaries (this provision in and of itself not constituting
permission to effectuate any asset Dispositions), provided that (i) so long as
                                                  -------------
there exists no Event of Default both immediately before and after giving effect
to such asset Dispositions and both immediately before and after any permitted
reinvestment and (ii) if a Default exists after giving effect to any such
Disposition, so long as such Default does not ultimately become an Event of
Default, the Commitment shall not be automatically and immediately reduced if
the Borrower in good faith intends to reinvest, and such proceeds are ultimately
reinvested within a 12 month period after any such asset Disposition, in assets
used in the Telecommunications Business, including, without limitation, the
internet, internet protocol, web hosting or electronic commerce of the Borrower
or any of the Wholly Owned Restricted Subsidiaries, acquisitions permitted under
Section 8.18 hereof or Investments permitted under Section 8.04 hereof.

<PAGE>

     (c) Option Date or Extension Final Maturity.  (i)  If the Borrower and the
SuperMajority Lenders have not agreed to extend the Working Line Loan final
maturity in accordance with the Extension Option and the Borrower has not
exercised the Conversion Option in accordance with the terms of Section 2.16,
then the Working Line Commitment shall automatically be reduced to zero on the
Option Date.  (ii)   If the Borrower and the SuperMajority Lenders exercised the
Extension Option, then the Working Line Commitment shall automatically be
reduced to zero on the Extension Final Maturity.

     (d) Specified Change of Control.  If any Specified Change of Control shall
have occurred and such Specified Change of Control has caused a Repayment Event,
each of the Revolver A Commitment, the Revolver B Commitment, the Swingline
Commitment and the Working Line Commitment shall immediately and automatically
be reduced to zero.

     (e) Voluntary Commitment Reductions.  The Borrower may from time to time,
upon notice to Administrative Agent not later than 1:00 p.m., three Business
Days in advance, terminate in whole or reduce in part the Commitment, as
designated by the Borrower; provided, however, that the Borrower shall pay the
                            --------  -------
accrued interest and the applicable accrued Commitment Fee on the amount of such
reduction and all amounts due, and any partial reduction shall be in an
aggregate amount which is an integral multiple of $5,000,000.

     (f) Commitment Reduction and Repayments, Generally.  Application of both
voluntary and mandatory reductions of the Commitments as between the Revolver A
Commitment, the Working Line Commitment and the Revolver B Commitment shall be
determined in accordance with the terms of Section 2.13(f) hereof. To the extent
outstanding Revolver A Advances exceed the Revolver A Commitment after any
reduction thereof, the Borrower shall repay, on the date of such reduction, any
such excess amount and all accrued interest thereon, the applicable Revolver A
Commitment Fee on the amount of such reduction and all amounts due.  To the
extent outstanding Revolver B Advances exceed the Revolver B Commitment after
any reduction thereof, the Borrower shall repay, on the date of such reduction,
any such excess amount and all accrued interest thereon, the applicable Revolver
B Commitment Fee on the amount of such reduction and all amounts due.  Prior to
the Conversion Date, to the extent outstanding Working Line Advances exceed the
Working Line Commitment after any reduction thereof, the Borrower shall repay,
on the date of such reduction, any such excess amount and all accrued interest
thereon, the applicable Working Line Commitment Fee on the amount of such
reduction and all amounts due.  Once reduced or terminated, none of the Revolver
A Commitment, the Working Line Commitment or the Revolver B Commitment may be
increased or reinstated.  No reduction of the Commitment, either voluntary or
mandatory shall relieve or alter the mandatory reduction and termination of the
Revolver A Commitment, the Working Line Commitment and the Revolver B Commitment
pursuant to this Section 2.11.

     2.12.  Funding Losses.  The Borrower may prepay the outstanding principal
balance of any Advance, in full at any time or in part from time to time in
accordance with the terms of Section 2.04 hereof, provided, that as a condition
                                                  --------
precedent to the Borrower's right to make, and any Lender's obligation to
accept, any such prepayment, each such prepayment shall be in the amount of 100%
of the principal amount to be prepaid, plus, with respect to LIBOR Advances,
accrued unpaid interest thereon to the date of prepayment, plus any other sums
which have become due to Administrative Agent and Lenders under the Loan Papers
on or before the prepayment date but have not been paid, plus (subject to
Section 11.08 hereof) any Consequential Loss.

                                      41
<PAGE>

     The Borrower agrees that each Lender is not obligated to actually reinvest
the amount prepaid in any specific obligation as a condition to receiving any
Consequential Loss, or otherwise.

     2.13.  Computations and Manner of Payments.

     (a) The Borrower shall make each payment hereunder and under the other Loan
Papers not later than 1:00 p.m. on the day when due in same day funds (by wire
transfer or otherwise) to Administrative Agent, for the account of Lenders
unless otherwise specifically provided herein, at Administrative Agent's office
at Bank of America Plaza, 901 Main Street, Dallas, Texas  75202, referencing
Qwest Communications International Inc.  No later than the end of each day when
each payment hereunder is made, the Borrower shall notify Loan Operations at
(214) 508-9192 or such other Person as Administrative Agent may from time to
time specify.

     (b) Unless Administrative Agent shall have received notice from the
Borrower prior to the date on which any payment is due hereunder that the
Borrower will not make payment in full, Administrative Agent may assume that
such payment is so made on such date and may, in reliance upon such assumption,
make distributions to Lenders.  If and to the extent the Borrower shall not have
made such payment in full, each Lender shall repay to Administrative Agent
forthwith on demand the applicable amount distributed, together with interest
thereon at the Federal Funds Rate, from the date of distribution until the date
of repayment.  The Borrower hereby authorizes each Lender, if and to the extent
payment is not made when due hereunder, to charge the amount so due against any
account of the Borrower with such Lender.

     (c) Subject to Section 11.08 hereof, interest on LIBOR Advances under the
Loan Papers shall be calculated on the basis of actual days elapsed but computed
as if each year consisted of 360 days.  Subject to Section 11.08 hereof,
interest on Base Advances, the Commitment Fee and other amounts due under the
Loan Papers shall be calculated on the basis of actual days elapsed but computed
as if each year consisted of 365 or 366 days, as applicable.  Such computations
shall be made including the first day but excluding the last day occurring in
the period for which such interest, payment or Commitment Fee is payable.  Each
determination by Administrative Agent or a Lender of an interest rate, fee or
commission hereunder shall be presumptive evidence of the validity of such
claim.  All payments under the Loan Papers shall be made in United States
dollars, and without setoff, counterclaim, or other defense.

     (d) Whenever any payment to be made hereunder or under any other Loan
Papers shall be stated to be due on a day other than 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 interest or fees, if applicable;

provided, however, if such extension would cause payment of interest on or
--------  -------
principal of LIBOR Advances to be made in the next following calendar month,
such payment shall be made on the next preceding Business Day.

     (e) Reference to any particular index or reference rate for determining any
applicable interest rate under this Agreement is for purposes of calculating the
interest due and is not intended as and shall not be construed as requiring any
Lender to actually obtain funds for any Advance at any particular index or
reference rate.

                                      42
<PAGE>

     (f) Notwithstanding anything to the contrary herein or in any Loan Paper,
to the extent the Borrower makes any voluntary prepayment, or voluntary
reduction of the Commitment under Section 2.04 or 2.11 hereof, or any mandatory
prepayment, or mandatory reduction of the Commitment under Section 2.05 or 2.11
hereof, then such reduction of Commitment or such prepayment shall be applied as
follows:

          (i) So Long as there Exists No Payment Default or Event of Default.

               (A) Repayments and Prepayments.  So long as there exists no
          Default under Section 9.01(a) hereof or any Event of Default, all
          voluntary and mandatory repayments and prepayments shall be applied as
          directed by the Borrower, and in the absence of direction by the
          Borrower, shall be deemed to repay and prepay (1) the Swingline
          Advances until all the outstandings under the Swingline Loan have been
          paid in full, (2) the Revolver B Advances until all the outstandings
          under the Revolver B Loan have been repaid in full, then (3) (only if
          the date such payment is received is prior to the Conversion Date),
          the Working Line Loan until all the outstandings under the Working
          Line Loan have been repaid in full, then (4) the Revolver A Loan until
          all the outstandings under the Revolver A Loan have been repaid in
          full, then (5) (only is the date such payment is received is after the
          Conversion Date), the Working Line Loan, until all outstandings under
          the Working Line loan have been repaid in full, and then (6) all
          remaining outstanding and unpaid Obligations; and

               (B) Commitment Reductions.  So long as there exists no Default
          under Section 9.01(a) hereof or any Event of Default, all voluntary
          and mandatory Commitment reductions shall be applied as directed by
          the Borrower, and in the absence of direction by the Borrower, shall
          be deemed to reduce, respectively, (1) the Revolver B Commitment until
          the Revolver B Commitment has been reduced to zero, then (2) if prior
          to the Conversion Date, the Working Line Commitment until the Working
          Line Commitment has been reduced to zero, then (3) the Revolver A
          Commitment until the Revolver A Commitment has been reduced to zero.

          (ii) During the Existence of a Payment Default or Event of Default.

               (A) Repayments and Prepayments.  So long as there exists a
          Default under Section 9.01(a) hereof or any Event of Default, all
          mandatory and voluntary prepayments shall be applied to first to
          Advances outstanding under the Swingline Loan, and secondly to the
          Revolver B Loan, the Revolver A Loan and the Working Line Loan, pro
          rata, until the Advances outstanding under each of the Revolver B
          Loan, the Revolver A Loan and the Working Line Loan have been repaid
          in full, and then to all remaining outstanding Obligations.

               (B) Commitment Reductions.  So long as there exists a Default
          under Section 9.01(a) hereof or any Event of Default, all mandatory
          and voluntary Commitment reductions shall be applied to the Revolver A
          Commitment, the Revolver B Commitment and, if prior to the Conversion
          Date to the Working Line Commitment, pro rata.

                                      43

     (g) At all times prior to the Lenders making a Revolver A Advance pursuant
to Section 2.02(h) hereof, the Administrative Agent shall distribute all
payments in respect of the Swingline Advances to the Swingline Bank.  At such
time, if any, that the Lenders make a Revolver A Advance pursuant to Section
2.02(h) hereof, the Administrative Agent shall distribute all payments in
respect of the Swingline Advances to the Lenders in accordance with the
respective Revolver A Specified Percentages.

     2.14.  Yield Protection; Changed Circumstances.

     (a) If any Lender determines that either (i) the adoption of any Applicable
Law, rule, regulation or guideline regarding capital adequacy and applicable to
commercial banks or financial institutions generally or any change therein, or
any change, after the date hereof, in the interpretation or administration
thereof by any Tribunal, central bank or comparable agency charged with the
interpretation or administration thereof, or (ii) compliance by any Lender (or
Lending Office of any Lender) with any request or directive applicable to
commercial banks or financial institutions generally regarding capital adequacy
(whether or not having the force of law) of any such authority, central bank or
comparable agency has the effect of reducing the rate of return on such Lender's
capital as a consequence of its obligations hereunder to a level below that
which such Lender could have achieved but for such adoption, change or
compliance (taking into consideration such Lender's policies with respect to
capital adequacy) by an amount reasonably deemed by such Lender to be material,
then from time to time, within fifteen days after demand by such Lender, the
Borrower shall pay to such Lender such additional amount or amounts as will
adequately compensate such Lender for such reduction.  Each Lender will notify
the Borrower of any event occurring after the date of this Agreement which will
entitle such Lender to compensation pursuant to this Section 2.14(a) as promptly
as practicable after such Lender obtains actual knowledge of such event;
provided, no Lender shall be liable for its failure or the failure of any other
--------
Lender to provide such notification.  A certificate of such Lender claiming
compensation under this Section 2.14(a), setting forth in reasonable detail the
calculation of the additional amount or amounts to be paid to it hereunder shall
be presumptive evidence of the validity of such claim.  If such Lender demands
compensation under this Section 2.14(a), the Borrower may at any time, on at
least five Business Days' prior notice to such Lender (i) repay in full the then
outstanding principal amount of LIBOR Advances, of such Lender, together with
accrued interest thereon, or (ii) convert the LIBOR Advances to Base Advances in
accordance with the provisions of this Agreement; provided, however, that the
                                                  --------  -------
Borrower shall be liable for the Consequential Loss arising pursuant to those
actions.

     (b) If, after the date hereof, any Tribunal, central bank or other
comparable authority, at any time imposes, modifies or deems applicable any
reserve (including, without limitation, any imposed by the Board of Governors of
the Federal Reserve System), special deposit or similar requirement against
assets of, deposits with or for the amount of, or credit extended by, any
Lender, or imposes on any Lender any other condition affecting a LIBOR Advance,
the Notes, or its obligation to make a LIBOR Advance, or imposes on any Lender
any other condition affecting a Letter of Credit; and the result of any of the
foregoing is to increase the cost to such Lender of making or maintaining its
Letter of Credit, LIBOR Advances, or to reduce the amount of any sum received or
receivable by such Lender under this Agreement or under the Notes, the Letters
of Credit or reimbursement obligations by an amount deemed by such Lender, to be
material, then, within five days after demand by such Lender, the Borrower shall
          ----
pay to such Lender such additional amount or amounts as will compensate such
Lender for such increased cost or reduction.  Each Lender will

                                      44
<PAGE>

(i) notify the Borrower of any event occurring after the date of this Agreement
that entitles such Lender to compensation pursuant to this Section 2.14(b), as
promptly as practicable after such Lender obtains actual knowledge of the event;
provided, no Lender shall be liable for its failure or the failure of any other
--------
Lender to provide such notification and (ii) use good faith and reasonable
efforts to designate a different Lending Office for LIBOR Advances, of such
Lender if the designation will avoid the need for, or reduce the amount of, the
compensation and will not, in the sole opinion of such Lender, be
disadvantageous to such Lender. A certificate of such Lender claiming
compensation under this Section 2.14(b), setting forth in reasonable detail the
computation of the additional amount or amounts to be paid to it hereunder shall
be presumptive evidence of the validity of such claim. If such Lender demands
compensation under this Section 2.14(b), the Borrower may at any time, on at
least five Business Days' prior notice to such Lender (i) repay in full the then
outstanding principal amount of LIBOR Advances, of such Lender, together with
accrued interest thereon, or (ii) convert the LIBOR Advances to Base Advances in
accordance with the provisions of this Agreement; provided, however, that the
                                                  --------  -------
Borrower shall be liable for the Consequential Loss arising pursuant to those
actions.

     (c) Notwithstanding any other provision of this Agreement, if the
introduction of or any change in or in the interpretation or administration of
any Law shall make it unlawful, or any central bank or other Tribunal shall
assert that it is unlawful, for a Lender to perform its obligations hereunder to
issue or maintain Letters of Credit, make LIBOR Advances or to continue to fund
or maintain LIBOR Advances hereunder, then, on notice thereof and demand
therefor by such Lender to the Borrower, (i) each LIBOR Advance will
automatically, upon such demand, convert into a Base Advance, (ii) the
obligation of such Lender to make, or to convert Advances into, LIBOR Advances
shall be suspended until such Lender notifies Administrative Agent and the
Borrower that such Lender has determined that the circumstances causing such
suspension no longer exist, and (iii) the obligation of such Lender to make or
maintain Letters of Credit shall be suspended until such Lender notifies
Administrative Agent and the Borrower that such Lender has determined that the
circumstances causing such suspension no longer exist.

     (d) Upon the occurrence and during the continuance of any Default or Event
of Default, (i) each LIBOR Advance will automatically, on the last day of the
then existing Interest Period therefor, convert into a Base Advance and (ii) the
obligation of each Lender to make, or to convert Advances into, LIBOR Advances
shall be suspended.

     (e) If any Lender notifies Administrative Agent that the LIBOR Rate for any
Interest Period for any LIBOR Advances will not adequately reflect the cost to
such Lender of making, funding or maintaining LIBOR Advances for such Interest
Period, Administrative Agent shall promptly so notify the Borrower, whereupon
(i) each such LIBOR Advance will automatically, on the last day of the then
existing Interest Period therefor, convert into a Base Advance and (ii) the
obligation of such Lender to make, or to convert Advances into, LIBOR Advances
shall be suspended until such Lender notifies Administrative Agent that such
Lender has determined that the circumstances causing such suspension no longer
exist and Administrative Agent notifies the Borrower of such fact.

     (f) Failure on the part of any Lender to demand compensation for any
increased costs, increased capital or reduction in amounts received or
receivable or reduction in return on capital pursuant to this Section 2.14 with
respect to any period shall not constitute a waiver of any Lender's

                                      45
<PAGE>

right to demand compensation with respect to such period or any other period,
subject, however, to the limitations set forth in this Section 2.14.

     (g) The obligations of the Borrower under this Section 2.14 shall survive
any termination of this Agreement, provided that, in no event shall the Borrower
                                   -------------
be required to make a payment under this Section 2.14 with respect to any event
of which the Lender making such claim had knowledge more than 12 months prior to
demand for such payment.

     (h) Determinations by Lenders for purposes of this Section 2.14 shall be
presumptively correct.  Any certificate delivered to the Borrower by a Lender
pursuant to this Section 2.14 shall include in reasonable detail the basis for
such Lender's demand for additional compensation and a certification that the
claim for compensation is consistent with such Lender's treatment of similar
customers having similar provisions generally in their agreements with such
Lender.

     (i) Notwithstanding any other provision of this Agreement, no Lender not
organized under the Laws of the United States or any State (or which has a Bank
Affiliate not organized under the Laws of the United States or any State) shall
be entitled to compensation pursuant to this Section 2.14 with respect to any
amount which would otherwise be due under this Section 2.14 but which is the
result of an act of a Tribunal of the country in which such Lender or Bank
Affiliate is organized.

     2.15.  Use of Proceeds.
     (a) Revolver A Advances and Swingline Advances. The Borrower agrees to use
the proceeds of the Revolver A Loan and the Swingline Facility exclusively to
(i) finance working capital, (ii) refinance certain permitted indebtedness on
the Original Closing Date, (iii) finance acquisitions permitted under Section
8.18 hereof, (iv) finance Capital Expenditures and (v) for other general
corporate purposes of the Borrower.

     (b) Working Line Advances and Revolver B Advances. The Borrower agrees to
use the proceeds of the Working Line Loan and the Revolver B Loan exclusively
to:

          (i)  Prior to such time as the Senior Unsecured Debt Rating is BBB- or
          Baa3 or better and the Conditional Early Release Unlimited Guaranty
          has been released in accordance with the terms of Section 11.14
          hereof:

               In accordance with certain of the Existing Financing
          Documentation, finance or refinance all or any part of the cost of,
          the construction, installation, acquisition or improvement by the
          Borrower or any Restricted Subsidiary (as defined in the Existing
          Financing Documentation) of the Borrower of any new
          "Telecommunications Assets" (as defined below) constructed, installed,
          acquired or improved after March 31, 1997, provided that (i) the
                                                     -------------
          proceeds of such debt are expended for such purposes within a 270 day
          period of making such construction, installation, acquisition or
          improvement, and (ii) the amount of such debt does not exceed 100% of
          the cost of the construction, installation, acquisition or improvement
          of the applicable Telecommunications Assets.  For purposes of this
          paragraph, "Telecommunications Assets" means all assets, rights
          (contractual or otherwise) and properties, whether tangible or
          intangible, used or intended for use in connection with the business
          of (A) transmitting or providing services relating to the

                                      46
<PAGE>

          transmission of, voice, data or video through owned or leased
          transmission facilities, (B) constructing, creating, developing or

          primarily related to those identified in (A) or (B) above, provided
                                                                     --------
          that the determination of what constitutes such businesses shall be
          ----
          made in good faith by the Board of Directors.

          (ii)  After the Senior Unsecured Debt Rating is BBB- or Baa3 or better
          and the Conditional Early Release Unlimited Guaranty has been released
          in accordance with the terms of Section 11.14 hereof:

     2.16.  Extension Option and Conversion Option Relating to the Working Line
Loan                                                            .

          (a) Extension Option.  On the Option Date, the Borrower, with the
     prior written consent of the SuperMajority Lenders and so long as there
     exists no Default or Event of Default, may elect to extend the maturity of
     the Working Line Loan for an additional 364 day period until the Extension
     Final Maturity.  Such election must be made no sooner than 60 days prior to
     the Option Date and no later than 3 days prior to the Option Date by
     written notice in accordance with the terms of Section 11.02 hereof to each
     Lender of its request to extend the final maturity of the Working Line
     Loan.  Each Lender shall, no later than 10 Business Days after receipt of
     such notice, give written notice to the Borrower and the Administrative
     Agent of its approval or disapproval of such extension.  Any Lender failing
     to give such notice shall be deemed to have approved such extension; but,
     upon the Option Date, its Working Line Specified Percentage shall be zero
     and such Lender shall not be participating in the Working Line Loan
     thereafter.  Notwithstanding anything herein to the contrary, no Lender
     shall be obligated to consent to such extension.  If the Borrower fails to
     receive the consent of Lenders having Working Line Specified Percentages
     totaling 100%, then, if SuperMajority Lenders have consented to such
     extension (i) only those consenting Lenders will have Working Line
     Specified Percentages in excess of zero, (ii) subject to the terms of
     Section 2.18 hereof, the Working Line Commitment shall be reduced by a
     dollar amount equal to the product of the non-consenting Lenders' Working
     Line Specified Percentages times the Working Line Commitment in effect on
     the day before the Option Date, (iii) subject to the terms of Section 2.18
     hereof, the Administrative Agent will notify each Lender of its reallocated
     Working Line Specified Percentage, the new Working Line Commitment and the
     reallocated Total Specified Percentage, (iv) the Borrower will pay all
     Consequential Costs incurred as a result of any such reallocation of
     Working Line Specified Percentages, (v) subject to the terms of Section
     2.18 hereof, the Borrower shall repay in full all portions of the
     Obligations representing such non-consenting Lenders' Working Line
     Specified Percentages of all outstanding Working Line Advances to such non-
     consenting Lenders, (vi) the Borrower shall execute and deliver new
     promissory notes to each extending Lender in the form required by the
     Administrative Agent and (vii) subject to satisfaction of each of the
     foregoing requirements, the Working Line Loan final maturity shall be

                                      47
<PAGE>

     automatically extended on the Option Date to the Extension Final Maturity.
     If the Borrower receives the consent of Lenders having Working Line
     Specified Percentages totaling 100%, then the Working Line Loan final
     maturity shall be automatically extended on the Option Date to the
     Extension Final Maturity, and each Lender will retain its Working Line
     Specified Percentage and the Working Line Commitment shall remain the same.

          (b) Conversion Option.  On the Option Date, or, if the Borrower and
     the Lenders have agreed to extend the Working Line Loan until the Extension
     Final Maturity, then the Extension Final Maturity, the Borrower, so long as
     there exists no Default or Event of Default on such date of conversion,
     shall have the option (which shall not require the consent of any Lender)
     to convert the Working Line Loan to a term loan.  Such election must be
     made no sooner than 60 days prior to the Option Date or Extension Final
     Maturity, as applicable, and no later than 30 days prior to the Option Date
     or Extension Final Maturity, as applicable, by written notice in accordance
     with the terms of Section 11.02 hereof to each Lender of such conversion.
     Prior to such conversion, the Borrower shall execute and deliver new
     promissory notes to each Lender in the form required by the Administrative
     Agent.  Upon such notice and receipt by the Lenders of the new promissory
     notes, the Working Line Loan shall automatically convert to a term loan on
     the Option Date or the Extension Final Maturity, as applicable.

     2.17.  Rights of Borrower in Respect of Consequential Losses.

     (a) Duty to Mitigate.  If (i) any Lender shall request compensation under
Section 2.14(a) or (b) hereof or (ii) any Lender delivers a notice described in
Section 2.14(c) or (e) hereof then such Lender shall use reasonable efforts
(which shall not require such Lender to suffer any disadvantage or burden
reasonably deemed by it (in good faith) to be significant, including without
limitation, to incur an unreimbursed loss or unreimbursed cost or expense or
otherwise take any action inconsistent with its internal policies or legal or
regulatory restrictions), promptly thereafter, (x) to file any certificate or
document reasonably requested in writing by the Borrower or (y) to assign its
Rights and delegate and transfer its obligations hereunder to another of its
offices, branches or Bank Affiliates, if such filing or assignment would reduce
its claims for compensation under Section 2.14(a) or (b) hereof or enable it to
withdraw its notice pursuant to Section 2.14(c) or (e) hereof, as the case may
be, in the future.  The Borrower hereby agrees to pay all reasonable costs and
expenses incurred by any Lender in connection with any such filing or
assignment, delegation and transfer.

     (b) Replacement of a Lender Upon Request for Compensation.  If any Lender
has requested compensation or reimbursement in accordance with the terms of
Section 2.14 hereof and (i) such request is not the result of any uniform
changes in the statutes or regulations for capital adequacy, and (ii) the
Borrower and such Lender are unable to reach a written agreement regarding such
request within 30 days following written notice by such Lender to the Borrower
and the Administrative Agent of such request, then after the expiration of 30
days following the delivery of the notice under Section 2.14 hereof, the
Borrower may replace such Lender in whole with another Lender acceptable to the
Arranging Agents pursuant to an Assignment and Acceptance and in accordance with
Section 11.04 hereof, provided that, such Lender is replaced at par value of all
                      -------------
Obligations owing such Lender plus all accrued interest and fees, provided
further, that Borrower pays the assignment and acceptance fee set forth in
Section 11.04(a) hereof for such replacement.

                                      48
<PAGE>

Until such time as any Lender is replaced by the Borrower, the Borrower shall
reimburse or compensate such Lender in accordance with the terms of Section 2.14
hereof.

     2.18.  Rights of Borrower in Respect of Failure of any Lender to Fund or
Extend the Option Date.    If any Lender shall either (a) breach its agreement
to make any Advance available in accordance with the terms of this Agreement
(and each other Lender shall have made its portion of the Advance available to
the Borrower), or (b) on the Option Date, shall fail to extend the Working Line
Loan for an additional 364 day period in accordance with the terms of Section
2.16(a) hereof when all such other Lenders have extended, then, in each case,
such Lender shall, promptly upon the written request of the Borrower to such
Lender and the Administrative Agent, assign all of its Rights and duties
hereunder and under the other Loan Papers pursuant to an Assignment and
Acceptance in accordance with the terms of Section 11.04 hereof to another
financial institution or lender designated by the Borrower and acceptable to the
Arranging Agents in accordance with the terms of Section 11.04 hereof, provided
                                                                       --------
that, notwithstanding the foregoing, in no event shall any Lender be required to
----
take any such action if (a) such Lender is owed any payments by the Borrower
pursuant to this Agreement or the other Loan Papers, (b) there exists any
Default or Event of Default.

                        ARTICLE III.  LETTERS OF CREDIT

     3.01.  Issuance of Letters of Credit.  The Borrower shall give the
Administrative Agent not less than three Business Days prior written notice of a
request for the issuance of a Letter of Credit, and the Administrative Agent
shall promptly notify each Lender of such request.  Upon receipt of the
Borrower's properly completed and duly executed Applications, and subject to the
terms of such Applications and to the terms of this Agreement, including,
without limitation, the satisfaction of the conditions set forth in Section 4.02
hereof, the Administrative Agent agrees to issue Letters of Credit on behalf of
the Borrower in an aggregate face amount not in excess of the Letter of Credit
Commitment.  No Letter of Credit shall have a maturity extending beyond the
earliest of (i) the Maturity Date, or (ii) one year from the date of its
issuance, or (iii) such earlier date as may be required to enable the Borrower
to satisfy its repayment obligations under Section 2.06 hereof.  Subject to such
maturity limitations and so long as no Default or Event of Default has occurred
and is continuing or would result from the renewal of a Letter of Credit, the
Letters of Credit may be renewed by the Administrative Agent in its discretion.
The Lenders shall participate ratably in any liability under the Letters of
Credit (including, without limitation, the Existing Letter of Credit)  and in
any unpaid reimbursement obligations of the Borrower with respect to any Letter
of Credit in their Revolver A Specified Percentages.  The amount of the Letters
of Credit issued and outstanding and the unpaid reimbursement obligations of the
Borrower for such Letters of Credit shall reduce the amount of Revolver A
Commitment available, so that at no time shall the sum of (i) all outstanding
Revolver A Advances in the aggregate, plus (ii) all outstanding Swingline
Advances in the aggregate, plus (iii) the aggregate face amount of all
outstanding Letters of Credit, plus (iv) (without duplication) all outstanding
reimbursement obligations related to Letters of Credit, exceed the Revolver A
Commitment, and at no time shall the sum of all Revolver A Advances by any
Lender made plus its ratable share of Swingline Advances and amounts available
to be drawn under the Letters of Credit and the unpaid reimbursement obligations
of the Borrower in respect of such Letters of Credit exceed its Revolver A
Specified Percentage of the Revolver A Commitment.

     3.02.  Letters of Credit Fee.  In consideration for the issuance of each
Letter of Credit, the Borrower shall pay to (a) the Administrative Agent for its
sole account, an application and

                                      49
<PAGE>

processing fee in the amount of the higher of (i) $350.00 and (ii) the product
of 1/8th of 1% multiplied by the face amount of such Letter of Credit on each
Letter of Credit, due and payable on the date of issuance of each Letter of
Credit, and (b) the Administrative Agent for the account of the Administrative
Agent and the Lenders in accordance with their Revolver A Specified Percentages,
a per annum fee for each Letter of Credit equal to the higher of (i) $350.00 and
(ii) the product of the Applicable Margin for a LIBOR Advance in effect on the
date of calculation multiplied by the face amount of each such Letter of Credit.
Each fee for each Letter of Credit under subsection (b) above shall be due and
payable to the Administrative Agent quarterly as it accrues, on each Quarterly
Date during the term of the Letter of Credit and on the expiration or renewal
and/or extension of each such Letter of Credit, beginning with the first such
Quarterly Date after the issuance of each Letter of Credit and ending on the
expiration date of each such Letter of Credit.

     3.03.  Reimbursement Obligations.

     (a) The Borrower hereby agrees to reimburse Administrative Agent
immediately upon demand by Administrative Agent, and in immediately available
funds, for any payment or disbursement made by Administrative Agent under any
Letter of Credit.  Payment shall be made by the Borrower with interest on the
amount so paid or disbursed by Administrative Agent from and including the date
payment is made under any Letter of Credit to and including the date of payment,
at the lesser of (i) the Highest Lawful Rate, and (ii) the sum of the Base Rate
in effect from time to time plus 2% per annum; provided, however, that if the
                                               --------  -------
Borrower would be permitted under the terms of Section 2.01, Section 2.02 and
Section 4.02 to borrow Revolver A Advances in amounts at least equal to their
reimbursement obligation for a drawing under any Letter of Credit, a Base
Advance by each Lender, in an amount equal to such Lender's Revolver A Specified
Percentage, shall automatically be deemed made on the date of any such payment
or disbursement made by Administrative Agent in the amount of such obligation
and subject to the terms of this Agreement.

     (b) The Borrower hereby also agrees to pay to Administrative Agent
immediately upon demand by Administrative Agent and in immediately available
funds, as security for their reimbursement obligations in respect of the Letters
of Credit under Section 3.03(a) hereof and any other amounts payable hereunder
and under the Notes, an amount equal to the aggregate amount available to be
drawn under Letters of Credit then outstanding, irrespective of whether the
Letters of Credit have been drawn upon, upon an Event of Default.  Any such
payments shall be deposited in a separate account designated "Qwest
Communications International Inc. Special Account" or such other designation as
Administrative Agent shall elect.  All such amounts deposited with
Administrative Agent shall be and shall remain funds of the Borrower on deposit
with Administrative Agent and may be invested by Administrative Agent as
Administrative Agent shall determine.  Such amounts may not be used by
Administrative Agent to pay the drawings under the Letters of Credit; however,
such amounts may be used by Administrative Agent as reimbursement for Letter of
Credit drawings which Administrative Agent has paid.  During the existence of an
Event of Default but after the expiration of any Letter of Credit that was not
drawn upon, the Borrower may direct the Administrative Agent to use any cash
collateral for any such expired Letter of Credit, if any, to reduce the amount
of the Obligations.  Any amounts remaining in the Qwest Communications
International Inc. Special Account, after the date of the expiration of all
Letters of Credit and after all Obligations have been paid in full, shall be
repaid to the Borrower promptly after such expiration and such payment in full.

                                      50
<PAGE>

     (c) The obligations of the Borrower under this Section 3.03 will continue
until all Letters of Credit have expired and all reimbursement obligations with
respect thereto have been paid in full by the Borrower and until all other
Obligations shall have been paid in full.

     (d) The Borrower shall be obligated to reimburse Administrative Agent upon
demand for all amounts paid under the Letters of Credit as set forth in Section
3.03(a) hereof; provided, however, if the Borrower for any reason fails to
reimburse Administrative Agent in full upon demand, whether by borrowing
Revolver A Advances to pay such reimbursement obligations or otherwise, the
Lenders shall reimburse Administrative Agent in accordance with each Lender's
Revolver A Specified Percentage for amounts due and unpaid from the Borrower as
set forth in Section 3.04 hereof; provided, however, that no such reimbursement
made by the Lenders shall discharge the Borrower's obligations to reimburse
Administrative Agent.

     (e) The Borrower, as to Letters of Credit issued for its account, shall
indemnify and hold harmless the Administrative Agent, the Lead Arranger, each
Lender and their respective affiliates, officers, directors, employees, agents

limitation, any transaction in which any Letter of Credit is being issued and in
connection with actions taken under the Letters of Credit or in connection
therewith, whether or not an Indemnified Party is a party thereto, whether or
not the transactions contemplated herein are consummated, and whether or not
such claim, damage, loss, liability or expense results from the negligence of

reimbursed by the Borrower in accordance with Section 3.03 hereof. Each Lender
specifically acknowledges that the Existing Letter of Credit which was issued
prior to the Original Closing Date shall be included in the definition of
Letters of Credit and each Lender shall be obligated to the Administrative Agent
with respect thereto on the identical terms and conditions it is obligated to
the Administrative Agent with respect to all of the other Letters of Credit,

-------------
of default under the Existing Letter of Credit on the Original Closing Date. All
amounts payable by any Lender under this subsection shall include interest
thereon at the Federal Funds Rate, from the date of the applicable draw to the
date of reimbursement by such Lender. No Lender shall be liable for the

Administrative Agent under any Application.  Administrative Agent shall have no
duties or responsibilities except those expressly set forth herein and those
duties and liabilities shall be subject to the limitations and qualifications

     (c) Neither Administrative Agent nor any of its directors, officers, or
employees shall be liable for any action taken or omitted (whether or not such
action taken or omitted is expressly set forth herein) under or in connection
herewith or any other instrument or document in connection herewith, except for
gross negligence or willful misconduct, and no Lender waives its right to
institute legal action against Administrative Agent for wrongful payment of any
Letter of Credit due to Administrative Agent's gross negligence or willful
misconduct.  Administrative Agent shall incur no liability to any Lender, the
Borrower or any Affiliate of the Borrower or Lender in acting upon any notice,

         -----------------------------------------
power and has taken all necessary corporate action to authorize it to borrow

respect to each Plan of the Borrower and each member of its Controlled Group
(other

                                      58
<PAGE>

than a Multiemployer Plan), all reports required under ERISA or any other
Applicable Law to be filed with any governmental authority, the failure of which
to file would reasonably result in liability of the Borrower, or any member of
its Controlled Group in excess of $10,000,000, have been duly filed.  All such
reports are true and correct in all material respects as of the date given. On
the Original Closing Date other than as disclosed to the Administrative Agent in
writing, no such Plan of the Borrower, or any member of its Controlled Group has
any accumulated funding deficiency (as defined in Section 412(a) of the Code)
(without regard to any waiver granted under Section 412 of the Code), nor has
any funding waiver from the Internal Revenue Service been received or requested.

the Code) (without regard to any waiver granted under Section 412 of the Code),
nor has any funding waiver from the Internal Revenue Service been received or
requested which is, or would reasonably be expected to cause, a Material Adverse
Change.  None of the Borrower, or any member of its Controlled Group has failed
to make any contribution or pay any amount due or owing as required by Section
412 of the Code or Section 302 of ERISA or the terms of any such Plan prior to
the due date under Section 412 of the Code and Section 302 of ERISA in excess of
$10,000,000.  There has been no ERISA Event or any event requiring disclosure
under Section 4041(c)(3)(C), 4068(f), 4063(a) or 4043(b) of ERISA with respect
to any Plan or trust of the Borrower, or any member of its Controlled Group
within 60 months prior to the Original Closing Date or thereafter, except as
disclosed to the Administrative Agent in writing.  The value of the assets of
each Plan (other than a Multiemployer Plan) of the Borrower and each member of
its Controlled Group equaled or exceeded the present value of the benefit
liabilities, determined on an on-going Plan basis, as defined in Title IV of
ERISA, of each such Plan as of the most recent valuation date using Plan
actuarial assumptions at such date.  There are no pending or, to the actual
knowledge of an Authorized Officer, threatened claims, lawsuits or actions
(other than routine claims for benefits in the ordinary course) asserted or
instituted against (i) the assets of any Plan or trust or against any fiduciary
of a Plan with respect to the operation of such Plan, or (ii) the assets of any
employee welfare benefit plan within the meaning of Section 3(1) or ERISA, or
against any fiduciary thereof with respect to the operation of any such plan,
except any such claims, lawsuits or actions that are not, and would not
reasonably be expected to cause, a Material Adverse Change.  None of the
Borrower, or any member of its Controlled Group has engaged in any non-exempt
prohibited transactions, within the meaning of Section 406 of ERISA or Section
4975 of the Code, in connection with any Plan, except such transactions which
are not, or would not in the aggregate reasonably be expected to cause, a
Material Adverse Change. None of the Borrower or any member of its Controlled
Group has incurred or reasonably expects to incur any liability under Title IV
of ERISA (other than premiums due under Section 4007 of ERISA to the PBGC) in
excess of $10,000,000.  None of the Borrower any member of its Controlled Group,
or, to the actual knowledge of any Authorized Officer, any organization to which
the Borrower or any member of its Controlled Group is a successor or parent
corporation within the meaning of ERISA Section 4069(b), has engaged in a
transaction within the meaning of ERISA Section 4069.  None of the Borrower or
any member of its Controlled Group maintains or has established any welfare
benefit plan within the meaning of Section 3(1) of ERISA which provides for
continuing benefits or coverage for any participant or any beneficiary of any
participant after such participant's termination of employment except as may be
required by the Consolidated Omnibus Budget Reconciliation Act of 1985, as
amended ("COBRA") and the regulations thereunder, and at the expense of the
participant or the beneficiary of the participant, or retiree medical
liabilities, except any such plan that would not reasonably be expected to
result in material liability to the Borrower or any Qwest Material Subsidiary.
Each of the Borrower and its Controlled Group which maintains a welfare

                                      59
<PAGE>

benefit plan within the meaning of Section 3(1) of ERISA has complied in all
material respects with any applicable notice and continuation requirements of
COBRA and the regulations thereunder, except where any such noncompliance has
not caused, or would not reasonably be expected to cause, liability to the
Borrower or any Qwest Material Subsidiary in excess of $10,000,000.

     (m) Margin Stock.  The Borrower is not, nor are any of the Restricted
         ------------
Subsidiaries, 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 within the meaning of Regulations T, U and X of the Board of
Governors of the Federal Reserve System, and no part of the proceeds of the
Advances will be used to purchase or carry any margin stock (as defined by
Regulation U) or to extend credit to others for the purpose of purchasing or
carrying any margin stock.  Not more than 25% of the assets of any of the
Borrower or any of its Subsidiaries are margin stock (as defined by Regulation
U).  None of the Borrower and its Subsidiaries, nor any agent acting on their
behalf, has taken any action which might cause this Agreement or any Loan Papers
to violate any regulation of the Board of Governors of the Federal Reserve
System or to violate the Exchange Act, in each case as in effect now or as the
same may hereafter be in effect from time to time.

     (n) Event of Default.  The Borrower and the Qwest Material Subsidiaries are
         ----------------
in compliance with all of the provisions of their articles of incorporation.
The Borrower and the Qwest Material Subsidiaries are in material compliance with
all of the provisions of their by-laws.  No event has occurred or failed to
occur, which has not been remedied or waived, the occurrence or non-occurrence
of which constitutes, or which with the passage of time or giving of notice or
both would constitute, an Event of Default.

     (o) Investment Company Act of 1940.  The Borrower is not, nor are any of
         ------------------------------
its Subsidiaries, required to register under the provisions of the Investment
Company Act of 1940, as amended (the "ICA").  Neither the entering into or
performance by the Borrower of this Agreement nor the issuance of the Notes, nor
the execution, delivery and performance of the obligations by the Borrower and
its Restricted Subsidiaries under the Loan Papers, violates any provision of the
ICA or requires any consent, approval, or authorization of, or registration
with, the Securities and Exchange Commission or any other governmental or public
body of authority pursuant to any provisions of the ICA.

     (p) Environmental.  On the Original Closing Date, no Authorized Officer has
         -------------
any actual knowledge that any Hazardous Substance has been installed on any real
property now owned by the Borrower or any of its Restricted Subsidiaries, except
(i) for Hazardous Substances the presence of which is not in violation of
Environmental Law in an amount which is not or would not reasonably be expected
to cause, liability to the Borrower or any Restricted Subsidiary in the
aggregate in excess of $5,000,000 or (ii) as set forth on Schedule 5.01(p)
                                                          ----------------
hereto.  On each date after the Original Closing Date on which this
representation is deemed to be made, no Authorized Officer of the Borrower or
any Restricted Subsidiary has any actual knowledge that any Hazardous Substance
has been installed in violation of law on any real property now owned by the
Borrower or any of the Restricted Subsidiaries except those installations which
are not, and would not reasonably be expected to cause, a Material Adverse
Change.  As of the Original Closing Date, except as disclosed on Schedule
                                                                 --------
5.01(p) hereto, to the actual  knowledge of an Authorized Officer, the Borrower
-------
and the Restricted Subsidiaries are not in material violation of or subject to
any existing, pending or material threatened formal investigation or formal
inquiry by any governmental authority, or subject to any material remedial
obligations under any applicable Environmental Laws.  On each date after the
Original

                                      60
<PAGE>

Closing Date on which this representation is deemed to be made, to the
actual knowledge of an Authorized Officer, the Borrower and the Restricted
Subsidiaries are not in violation of or subject to any existing, pending  or
threatened formal investigation or inquiry by any governmental authority or to
any remedial obligations under any applicable Environmental Laws which in each
case is, or would reasonably be expected to cause, a Material Adverse Change.
To the actual knowledge of an Authorized Officer, the Borrower and the
Restricted Subsidiaries are not required to obtain any material permits,
Licenses or similar authorizations to construct, occupy, operate or use any
buildings, improvements, fixtures, and equipment forming a part of any real
property of the Borrower or any Restricted Subsidiary by reason of any
applicable Environmental Laws, except those that have been obtained, or which
the failure to obtain has not, and would not reasonably be expected to cause, a
Material Adverse Change.  As of the  Original Closing Date, except as set forth
in Schedule 5.01(p) hereto, no Authorized Officer has actual knowledge that any
   ----------------
Hazardous Substances or solid wastes have been disposed of on the real property
of the Borrower or any of its Restricted Subsidiaries in violation of any
applicable Environmental Law, except such violations which are not, and would
not reasonably be expected to cause, liability to the Borrower and/or the
Restricted Subsidiaries in the aggregate in excess of $5,000,000.  As of the
Original Closing Date, except as set forth in Schedule 5.01(p) hereto, no
                                              ----------------
Authorized Officer has actual knowledge that any Hazardous Substances or solid
wastes have been released on or to the real property of the Borrower or any of
its Restricted Subsidiaries in violation of any applicable Environmental Law,
except such violations which are not, and would not reasonably be expected to
cause, liability to the Borrower and/or the Restricted Subsidiaries in the
aggregate in excess of $10,000,000.  On each date after the Original Closing
Date on which this representation is deemed to be made, no Authorized Officer of
the Borrower and the Restricted Subsidiaries has actual knowledge that any
Hazardous Substances or solid wastes have been disposed of or otherwise released
on or to the real property of the Borrower or any of the Restricted
Subsidiaries, in violation of the applicable Environmental Laws, except any such
disposal or release which is not, and would not reasonably be expected to cause,
a Material Adverse Change.

     (q) Subsidiaries.  As of the Original Closing Date,, the Borrower has no
         ------------
Subsidiaries other than those Subsidiaries specifically disclosed in part (a) of

Schedule 5.01(q) hereto and has no equity investments in any other Person other
----------------
than those specifically disclosed in part (b) of Schedule 5.01(q) hereto.
                                                 ----------------

     (r) Broker's Fees.  No broker's, finder's or other similar fee or
         -------------
commission will be payable by the Borrower (other than to the Agents and the
Lenders hereunder) with respect to the making of the Commitment or the Advances
hereunder.

     (s) Intellectual Property.  To the actual knowledge of the Authorized
         ---------------------
Officers as of the Original Closing Date, the Borrower and its Restricted
Subsidiaries have obtained all licenses of material patents, trademarks,
service-marks, trade names, copyrights, and other rights from third parties that
are necessary for the operation of their business as presently conducted.  On
each date after the Original Closing Date on which this representation is deemed
to be made, the Borrower and the Restricted Subsidiaries have obtained all
Licenses of patents, trademarks, service-marks, trade names, copyrights and
other similar rights that are necessary for the operation of their business as
presently conducted, except those, the failure of which to obtain has not
caused, and would not reasonably be expected to cause, a Material Adverse
Change.  Nothing has come to the attention of the Borrower or any of the
Restricted Subsidiaries to the effect that (i) any process, method, part or
other material presently contemplated to be employed by the Borrower or any
Qwest Material Subsidiary may infringe any patent, trademark, service-mark,
trade name, copyright, or other right

                                      61
<PAGE>

owned by any other Person except to the extent Borrower or any of the Restricted
Subsidiaries has obtained a License therefor, or (ii) there is pending or
overtly threatened any claim or Litigation against or affecting the Borrower or
any Qwest Material Subsidiary contesting its right to sell or use any such
process, method, part or other material, except in the case of clause (i) and
(ii) above, any such event or circumstance which has not caused, and would not
reasonably be expected to cause, a Material Adverse Change.

     (t) Accuracy of Borrower Information.  On the Original Closing Date,
         --------------------------------
neither this Agreement nor any other document, certificate or statement (in each
case, taken as a whole but excluding the Offering Memorandum) which has been
furnished to any Lender by or on behalf of the Borrower or any of its
Subsidiaries in connection herewith contained any materially untrue statement of
a material fact or omitted to state a material fact necessary in order to make
the statement contained herein and therein not materially misleading at the time
it was furnished in light of the circumstances under which they were made,

provided that notwithstanding anything to the contrary in this Agreement or in
-------------
the Loan Papers, the Borrower makes no representation, warranty or guaranty as
to any projections furnished to the Lenders except that they were prepared in
good faith by the Borrower on the basis of assumptions which the Borrower
believed were reasonable as of the date of such projections.  On each date after
the Original Closing Date on which this representation is deemed to be made, the
Borrower represents that none of the regular or periodic reports, or any
registration statement or prospectus filed by the Borrower or any Restricted
Subsidiary with the Securities and Exchange Commission (or any successor agency)
contains any materially untrue statement of a material fact or omits to state a
material fact necessary in order to make the statement contained therein not
materially misleading at the time of such filing in light of the circumstances
under which they were made.  The historical financial statements of the Borrower
and Guarantor contained in the Offering Memorandum present fairly in all
material respects and in accordance with GAAP (subject to year end adjustments
and the absence of footnotes as to the Borrower's unaudited financial statements
contained therein) the financial position of the Borrower and the Guarantor,
respectively, and their respective consolidated Subsidiaries as of the date of
such financial statements.

     (u) Year 2000 Compliance.  The Year 2000 Problem has not resulted in, and
         --------------------
the Borrower reasonably believes that the Year 2000 Problem will not result in,
a Material Adverse Change.

     (v) Existing Financing.  The Loans and the Conditional Early Release
         ------------------
Unlimited Guaranty of the Loans and all Obligations are senior to or pari passu
with all Existing Financing.  Nothing in this Agreement and the other Loan
Papers violates any provision of the Existing Financing Documentation, and no
consent is required in connection with any of the Existing Financing
Documentation in order to execute, deliver and perform under this Agreement and
the other Loan Papers.  To the actual knowledge of the Authorized Officers,
there exists no "Default" or "Event of Default" as defined in, and under any of
the Existing Financing Documentation, or any other event or circumstance which
causes a Repayment Event with respect to any of the Existing Financing.  All
notices required by any Existing Financing Documentation regarding the
execution, delivery or performance by the Borrower or any Restricted Subsidiary
of the Loan Papers have been given in accordance with the terms of the Existing
Financing Documentation.

     (w) Fibers and Fiber Capacity. As of the Original Closing Date, the
         -------------------------
Borrower and its Restricted Subsidiaries own or have the right to use through
the Maturity Date not less than 24

                                      62
<PAGE>

optical fibers on a weighted average route mile basis on the Backbone (which
such fibers are not subject to any transfer, disposition or IRU Agreement
granting an IRU to any Person other than the Borrower or any Restricted
Subsidiary), and such fiber capacity is sufficient, on a weighted average route
mile basis, to meet the business plan of the Borrower.

     (x) Sinking Funds and Defeasance.  As of the Original Closing Date, no
         ----------------------------
documentation relating to any Debt for Borrowed Money of the Borrower or any
Restricted Subsidiary has any provision granting any creditor a sinking fund or
a right to require a defeasance of the obligations owing to it.

     5.02.  Survival of Representations and Warranties.  All representations
and warranties made under this Agreement and the other Loan Papers shall be
deemed to be made at and as of the Original Closing Date and at and as of the
date of each Advance (excluding each Refinancing Advance), and each shall be
true and correct in all material respects when made (except those
representations and warranties that specifically speak as of a particular date).
All such representations and warranties shall survive, and not be waived by, the
execution hereof by any Lender, any investigation or inquiry by any Lender, or
by the making of any Advance under this Agreement.

                        ARTICLE VI.  GENERAL COVENANTS

     So long as any of the Obligations are outstanding and unpaid or the
Commitment or any Letter of Credit is outstanding (whether or not the conditions
to borrowing have been or can be fulfilled), and subject to the terms of Section
9.08 hereof:

     6.01.  Preservation of Existence and Similar Matters.

     (a) The Borrower shall, and shall cause each Qwest Material Subsidiary to,

Tribunal (regulatory or otherwise) which the Borrower or such Qwest Material
Subsidiary deems reasonably necessary or advisable to conduct its business in
the ordinary course, and (ii) its existence (except as permitted by Section 8.05
hereof); and

     (b) The Borrower shall, and shall cause each Restricted Subsidiary to,
qualify and remain qualified and authorized to do business in each jurisdiction
in which the character of its Properties or the nature of its business requires
such qualification or authorization, except where the failure to do so is not,
and would not reasonably be expected to cause, a Material Adverse Change.

     6.02.  Business; Compliance with Applicable Law.    The Borrower shall, and
shall cause the Restricted Subsidiaries to (a) engage primarily in the
Telecommunications Business, including, without limitation, the internet,
internet protocol, web hosting or electronic commerce, and (b) comply in all
material respects with the requirements of all material Applicable Law.

     6.03.  Maintenance of Properties.  The Borrower shall, and shall cause

<PAGE>

order and condition, taken as a whole, and from time to time make or cause to be
made all appropriate repairs, renewals, replacements, additions, betterments and
improvements thereto.

     6.04.  Accounting Methods and Financial Records.  The Borrower shall, and
shall cause each Restricted Subsidiary to, maintain a system of accounting
established and administered in accordance with GAAP and keep adequate records
and books of account in which complete entries will be made and all transactions

the Restricted Subsidiaries to, maintain a fiscal year ending on December 31.

     6.05.  Insurance.  The Borrower shall, and shall cause each Restricted
Subsidiary to, maintain insurance from responsible companies in such amounts and
against such risks as shall be customary and usual in the industry for companies
of similar size and capability.  The Borrower shall use commercially reasonable
efforts to cause each insurance policy to provide for at least 30 days' prior
notice to the Administrative Agent of any proposed termination or cancellation
of such policy, whether on account of default or otherwise.

     6.06.  Payment of Taxes and Claims.  The Borrower shall, and shall cause
each of its Restricted Subsidiaries to, pay and discharge all federal and other
material Taxes, assessments and governmental charges or levies imposed upon it
or its income or Properties prior to the date on which penalties attach thereto
which are shown on such Person's Tax returns to be due and payable, and all
lawful material claims for labor, materials and supplies which, if unpaid, might
become a Lien upon any of their Properties or assets, except those Taxes,
assessments and charges which are immaterial or contested by the Borrower
diligently in good faith, and for which adequate reserves have been established
in accordance with GAAP.  The Borrower shall, and shall cause each of its
Restricted Subsidiaries to, timely file all information returns required by
federal Tax Authorities, and all material information returns required by state
or local Tax authorities.

     6.07.  Visits and Inspections.  The Borrower shall, and shall cause each
Restricted Subsidiary to, promptly, permit representatives of the Administrative
Agent and the Arranging Agents, or any Lender accompanied by the Administrative
Agent from time to time, upon prior notice reasonable under the circumstances,
to (a) visit and inspect the Properties of the Borrower and each Restricted
Subsidiary during normal business hours (unless there exists an Event of Default
in which case during such hours as is reasonable under the circumstances), (b)
inspect and make extracts from and copies of the Borrower's and each Restricted
Subsidiary's books and records, in each case as reasonable under the
circumstances, (c) discuss with the Borrower's and each Restricted Subsidiary's
officers (and during an Event of Default, with the Auditors together with an
Authorized Officer of the Borrower), its business, assets, liabilities,
financial positions, results of operations and business prospects, and (d) make
reasonable informational requests of the Auditors from time to time, with
respect to which the Borrower shall be obligated to procure such information
from the Auditors.

     6.08.  Use of Proceeds.  The Borrower agrees that the proceeds of the
Loans shall be used in accordance with the terms of Section 2.15 hereof.

                                      64
<PAGE>

     6.09.  Indemnity.   The Borrower agrees to indemnify and hold harmless
the Administrative Agent, the Lead Arranger, the Arranging Agents, the Co-
Arrangers, the Co-Syndication Agents, each Lender and their respective
affiliates, officers, directors, employees, agents and advisors (each, an
"Indemnified Party") from and against any and all claims, damages, losses,
liabilities and expenses (including, without limitation, the reasonable fees and
expenses of counsel and the allocated cost of internal counsel) which may be
incurred by or asserted or awarded against any Indemnified Party, in each case
arising out of or in connection with or by reason of, or in connection with the
preparation for a defense of, any investigation, litigation or proceeding
arising out of, related to or in connection with the Loans, including without
limitation, any transaction in which the proceeds of any borrowing are or are to
be applied, whether or not an Indemnified Party is a party thereto, whether or
not the transactions contemplated herein are consummated, and whether or not
such claim, damage, loss, liability or expense results from the negligence of
such Indemnified Party unless and only to the extent that as to any Indemnified
Party, it shall be determined in a final, non-appealable judgment by a court of
competent jurisdiction that such losses, claims, damages, liabilities, or
expenses resulted from such Indemnified Party's gross negligence or willful
misconduct.  Borrower will not settle or consent to judgment with respect to any
investigation, litigation, or proceeding without the prior written consent of
the Administrative Agent and any affected Indemnified Party, unless such
settlement or consent includes an unconditional release of each such Indemnified
Party or unless each Indemnified Party is entitled to be indemnified under this
Section 6.09 (which entitlement the Borrower will confirm to such Indemnified
Party in writing, if requested).  The Borrower shall periodically, upon request,
reimburse each Indemnified Party for its reasonable legal and other actual
expenses (including the costs of any investigation and preparation) incurred in
connection with any indemnified matter.  The Borrower agrees that no Indemnified
Party shall have any liability for any indirect or consequential damages in
connection with its activities related to the Loans.  The reimbursement,
indemnity and contribution obligations under this Section shall be in addition
to any liability which the Borrower may otherwise have, shall extend upon the
same terms and conditions to each Indemnified Party, and shall be binding upon
and inure to the benefit of any successors, assigns, heirs and personal
representatives of the Borrower, the Administrative Agent, the Lenders and all
other Indemnified Party.  This Section shall survive any termination of this
Agreement and repayment of the Obligations.

     6.10.  Environmental Law Compliance.  The use which the Borrower or any
of its Restricted Subsidiaries intends to make of any real Property owned by it
will not result in the disposal or other release of any Hazardous Substance or
solid waste on or to such real Property in violation of any Environmental Law,
except any such violation which is not, and would not reasonably be expected to
cause, a Material Adverse Change.  As used herein, the term "release" as used in
this Section shall have the meanings specified in CERCLA (as defined in the
definition of applicable Environmental Laws), and the terms "solid waste" and
"disposal" shall have the meaning specified in RCRA (as defined in the
definition of applicable Environmental Laws); provided, however, that if CERCLA
or RCRA is amended so as to broaden or narrow the meaning of any term defined
thereby, such broader or narrower meaning shall apply subsequent to the
effective date of such amendment; and provided further, to the extent that any
other law applicable to the Borrower, any of its Restricted Subsidiaries or any
of their properties and assets establishes a meaning for "hazardous substance,"
"release," "solid waste," or "disposal" which is broader than that specified in
either CERCLA or RCRA, such broader meaning shall apply.  The Borrower and each
Restricted Subsidiary agrees to indemnify and hold the Administrative Agent and
each Lender harmless from and against, and to reimburse them with respect to,
any and all claims, damages, losses, liabilities and expenses (including
reasonable attorneys' fees and courts costs) asserted or awarded against or

                                      65
<PAGE>

incurred by any of them by reason of or arising out of transactions contemplated
by this Agreement and (a) the failure of the Borrower or any of its Restricted
Subsidiaries to perform any obligation hereunder regarding asbestos or
applicable Environmental Laws, (b) any violation by the Borrower or Restricted
Subsidiary on or before the Release Date of any applicable Environmental Law in
effect on or before the Release Date, and (c) any act, omission, event or
circumstance existing or occurring on or prior to the Release Date, involving
the presence on such real Property or release from such real Property of
Hazardous Substances or solid wastes disposed of or otherwise released on or
prior to the Release Date, resulting from or in connection with the ownership by
the Borrower or any Restricted Subsidiary of the real Property, regardless of
whether the act, omission, event or circumstance constituted a violation of any
applicable Environmental Law at the time of its existence or occurrence, or
whether the act, omission, event or circumstance is caused by or relates to the
negligence of any indemnified Person; provided, that the Borrower shall not be
under any obligation to indemnify the Administrative Agent or any Lender to the
extent that any such liability arises as the result of the gross negligence or
willful misconduct of such Person, as finally judicially determined by a court
of competent jurisdiction.  The provisions of this Section shall survive the
Release Date and shall continue thereafter in full force and effect.

     6.11.  Restricted Subsidiary Designation.    The Borrower agrees that each
Restricted Subsidiary on the Original Closing Date will remain a Restricted
Subsidiary until the Obligations have been repaid in full and the Commitment has
been terminated, unless any such Restricted Subsidiary that is not a Qwest
Material Subsidiary has been Disposed of in accordance with the terms of Section
8.05(a)(ii)(A) hereof.  The Borrower agrees that, without the consent of the
Majority Lenders, the  Designated U S WEST Restricted Subsidiary will remain a
Restricted Subsidiary until the Obligations have been repaid in full and the
Commitment has been terminated.

     6.12.  Fiber Capacity.   The Borrower shall, and shall cause its Restricted
Subsidiaries to, at all times maintain ownership of or the right to use through
the Maturity Date (or until all Obligations are paid in full) not less than 24
optical fibers on a weighted average route mile basis on the Backbone, which
such fibers may not be transferred, disposed of or made subject to an IRU
Agreement granting an IRU to any Person other than the Borrower or any
Restricted Subsidiary if such transfer, disposal or IRU Agreement would result
in the Borrower and its Restricted Subsidiaries owning or having the right to
use less than 24 optical fibers on a weighted average route mile basis on the
Backbone through the Maturity Date (or until all Obligations are paid in full).

     6.13.  UCC Filings.    The Borrower shall, and shall cause its Restricted
Subsidiaries to, agree to file UCC-3 releases for all UCC filings recorded
against the Borrower and its Restricted Subsidiaries, which such UCC filings
evidence Debt that has been repaid in full and extinguished and do not evidence
Liens permitted under Section 8.03 hereof.

     6.14.  Sinking Funds and Defeasance.   To the extent that the Borrower or
any Restricted Subsidiary agrees in connection with the incurrence of any Debt
for Borrowed Money to a sinking fund or defeasance, the Borrower shall, and
shall cause each of its Restricted Subsidiaries to, grant to the Administrative
Agent and the Lenders proportionately similar rights to a sinking fund or
defeasance with respect to the Obligations.

     6.15.  Reimbursement of Costs and Expenses.   Within 30 days after the
Amendment and Restatement Closing Date,  the Borrower shall reimburse the
Administrative Agent for the reasonable costs, fees and expenses (including the
reasonable fees and expenses of Special Counsel)

                                      66
<PAGE>

incurred by the Administrative Agent in connection with the negotiation,
preparation and execution of this Agreement and the other Loan Papers.

                      ARTICLE VII.  INFORMATION COVENANTS

     So long as any of the Obligations are outstanding and unpaid or the
Commitment or any Letter of Credit is outstanding (whether or not the conditions
to borrowing have been or can be fulfilled), the Borrower shall, subject to
Section 9.08 hereof,  furnish or cause to be furnished to the Administrative
Agent two copies of the following:

     7.01.  Quarterly Financial Statements and Information.  Within 60 days
after the end of each fiscal quarter (except the fourth fiscal quarter), (a)
consolidated balance sheets of the Borrower and the Restricted Subsidiaries, and
(b) either (i) a copy of the Form 10-Q (including all financial statements
contained herein) filed by the Borrower or (ii) consolidated balance sheets of
the Borrower and its Subsidiaries, each as at the end of such quarter, and the
related consolidated and consolidating statements of income and consolidated
statements of changes in cash for such quarter and for the elapsed portion of
the year ended with the last day of such quarter, all of which shall be
certified by an Authorized Officer of the Borrower on behalf of the Borrower,
to, in his or her opinion, present fairly in all material respects, in
accordance with GAAP (except that such financial statements may be subject to
year-end audit adjustments and do not have to contain footnotes), the financial
position and results of operations of (A) the Borrower and the Restricted
Subsidiaries, and (B) the Borrower and its Subsidiaries, respectively, as at the
end of and for such period, and for the elapsed portion of the year ended with
the last day of such period.

     7.02.  Annual Financial Statements and Information.

     (a) Within 120 days after the end of each fiscal year, a copy of (i) the

     9.02.  Remedies upon Default.  If an Event of Default described in
Section 9.01(f) shall occur, the aggregate unpaid principal balance of and
accrued interest on all Advances and all other Obligations shall, to the extent
permitted by applicable Law, thereupon become due and payable concurrently
therewith, and the Commitment shall be concurrently automatically reduced to
zero and terminated, all without any action by Administrative Agent or any
Lender, and without diligence, presentment, demand, protest, notice of protest
or intent to accelerate, or notice of any other kind, all of which are hereby
expressly waived.  Subject to the foregoing sentence, if any Event of Default
shall occur and be continuing, Administrative Agent may at its election, and
shall at the direction of Majority Lenders, do any one or more of the following:

     (a) Declare the entire unpaid balance of all Obligations immediately due
and payable, whereupon it shall be due and payable without diligence,
presentment, demand, protest, notice of protest or intent to accelerate, or
notice of any other kind (except notices specifically provided for under Section
9.01 hereof), all of which are hereby expressly waived (except to the extent
waiver of the foregoing is not permitted by applicable Law);

     (b) Terminate any of the Revolver A Commitment, the Working Line Commitment
or the Revolver B Commitment, or terminate all of the Commitments;

     (c) Reduce any claim of Administrative Agent and Lenders to judgment;

     (d) Demand (and the Borrower shall pay to Administrative Agent) immediately
upon demand and in immediately available funds, the amount equal to the
aggregate amount of the Letters of Credit then outstanding as cash collateral,
irrespective of whether such Letters of Credit have been drawn upon, all as set
forth and in accordance with the terms of provisions of Article III hereof.  The
Administrative Agent shall promptly advise the Borrower of any such declaration
or demand but failure to do so shall not impair the effect of such declaration
or demand; and

     (e) Exercise any Rights afforded under any Loan Papers, by Law, including
but not limited to the UCC, at equity, or otherwise.

     9.03.  Cumulative Rights.  All Rights available to Administrative Agent
and Lenders under the Loan Papers shall be cumulative of and in addition to all
other Rights granted thereto at Law or in equity, whether or not amounts owing
thereunder shall be due and payable, and whether or not the Administrative Agent
or any Lender shall have instituted any suit for collection or other action in
connection with the Loan Papers.

     9.04.  Waivers.  The acceptance by Administrative Agent or any Lender at
any time and from time to time of partial payment of any amount owing under any
Loan Papers shall not be deemed to be a waiver of any Default or Event of
Default then existing.  No waiver by Administrative Agent or any Lender of any
Default or Event of Default shall be deemed to be a waiver of any Default or
Event of Default other than such Default or Event of Default.  No delay or
omission by Administrative Agent or any Lender in exercising any Right under the
Loan Papers shall impair such Right or be construed as a waiver thereof or an
acquiescence therein, nor shall any single or partial exercise of any such Right
preclude other or further exercise thereof, or the exercise of any other Right
under the Loan Papers or otherwise.

                                      89

     9.05.  Performance by Administrative Agent or any Lender.  Should any
covenant of any Obligor or Restricted Subsidiary fail to be performed in
accordance with the terms of the Loan Papers, Administrative Agent may, at its
option, perform or attempt to perform such covenant on behalf of such Obligor or
Restricted Subsidiary.  Notwithstanding the foregoing, it is expressly
understood that the Administrative Agent does not assume, and shall not ever
have, except by express written consent of the Administrative Agent, any
liability or responsibility for the performance of any duties or covenants of
any Obligor or Restricted Subsidiary.

     9.06.  Expenditures.  The Borrower shall reimburse Administrative Agent
for any reasonable sums spent by it in connection with the exercise of any Right
under Section 9.05 hereof.  Such sums shall bear interest at the lesser of (a)
the Base Rate (whether or not in effect), plus 2.00% per annum and (b) the
Highest Lawful Rate, from 15 days after the date the Administrative Agent makes
demand to the Borrower for reimbursement of such amount until the date of
repayment by the Borrower.

     9.07.  Control.  None of the covenants or other provisions contained in
this Agreement shall, or shall be deemed to, give Administrative Agent or any
Lender any Rights to exercise control over the affairs and/or management of any
of the Borrower or any of its Subsidiaries being limited to the Rights to
exercise the remedies provided in this Article; provided, however, that if
                                                --------  -------
Administrative Agent or any Lender becomes the owner of any partnership, stock

     9.08.  Compliance Concerning U S WEST Companies and Their Assets .

          (a) Notwithstanding anything in this Agreement or in any of the Loan
     Papers to the contrary (but subject to subsections (b) and (c) below),
     after the Acquisition Date, no breach of this Agreement, Default or Event
     of Default shall be deemed to have occurred and no condition precedent set
     forth in Article IV hereof shall fail to be satisfied, as a result of:

               (i) the inaccuracy of any representation or warranty contained in
          Article V hereof,

               (ii) any failure to comply with the provisions of any affirmative
          covenant contained in Article VI hereof (other than any provisions
          contained in Sections 6.07 and 6.11 hereof),

               (iii)  any failure to comply with any information covenant
          contained in Article VII hereof (other than any provisions contained
          in Sections 7.01, 7.02 , 7.04(d) and 7.07 hereof),

               (iv) any failure to comply with any negative covenant contained
          in Article VIII hereof (other than Sections 8.01, 8.02, 8.04, 8.07 and
          8.16 hereof) and

               (v) the occurrence of any event that would otherwise constitute
          any Default or Event of Default contained in Article IX hereof (other
          than under Sections 9.01(e), (o), (q) and (r) hereof),

                                      90
<PAGE>

     in each case set forth in (i) through (v) above, only to the extent that
     any such inaccuracy of any such representation or warranty, or failure to
     comply, failure to satisfy a condition precedent, Default or Event of
     Default is wholly or in part caused by, or attributable to, any U S WEST
     Company or the assets or liabilities of any U S WEST Company (a "U S WEST
     Event");

          (b) Section 9.08(a) above shall only be effective when:

               (i) at least one of the U S WEST Restricted Subsidiaries has in
          effect, and is bound by, a bank credit facility in excess of
          $100,000,000,

               (ii) the U S WEST Event has not caused the occurrence of a
          Material Adverse Effect, and

               (iii)  the Original Borrower and the Original Subsidiaries are
          otherwise in compliance with all such provisions exempting U S WEST
          Companies; and

          (c) Notwithstanding any provision of Section 9.08(a) above:

               (i) each U S WEST Restricted Subsidiary shall be subject to, and
          bound by, the terms and provisions contained in Sections 6.07, 6.11,
          7.01, 7.02., 7.04(d), 7.07, 8.01, 8.02, 8.04, 8.07 and 8.16 hereof,

               (ii) any Default or Event of Default under Sections 9.01(a), (e),
          (o), (q) and (r) that is wholly or in part caused by, or attributable
          to, any of the U S WEST Restricted Subsidiaries or the assets or
          liabilities of any of the U S WEST Restricted Subsidiaries, shall be a
          Default or Event of Default hereunder, as applicable, and

               (iii)  Although, in accordance with the terms of this Section
          9.08, the U S WEST Restricted Subsidiaries are not subject to the
          limitations of certain of the negative covenants of this Agreement,
          each U S WEST Restricted Subsidiary shall be included in any
          exceptions to such limitations to the extent that the U S WEST
          Restricted Subsidiaries would, but for this Section 9.08, fall within
          such exceptions.  For the avoidance of doubt, (1)  the U S WEST
          Restricted Subsidiaries that meet the definition of "Wholly Owned
          Restricted Subsidiaries", shall be considered and included in the
          definition of "Wholly Owned Restricted Subsidiaries" for purposes of
          (A) the parenthetical in Section 8.08 hereof, (B) Sections 8.10
          (a)(i), (b)(ii) and  8.11 (a) hereof, and (C) the second reference
          thereto in Section 8.18 (b) hereof, and (2)  the U S WEST Restricted
          Subsidiaries shall be considered "Restricted Subsidiaries" for
          purposes of the second and fourth references thereto in Section 8.17
          hereof.

                     ARTICLE X.  THE ADMINISTRATIVE AGENT

     10.01.  Authorization and Action.  Each Lender hereby appoints and
authorizes Administrative Agent to take such action as Administrative Agent
deems necessary on its behalf and to exercise such powers under this Agreement
and the other Loan Papers as are delegated to the Administrative Agent by the
terms of the Loan Papers, together with such powers as are reasonably incidental
thereto.  As to any matters not expressly provided for by this Agreement and the
other Loan Papers (including without limitation enforcement or collection of the
Notes), Administrative Agent shall not be required to exercise any discretion or
take any action, but shall be required to act or to refrain from acting (and
shall be fully protected in so acting or refraining from acting) upon the
instructions of Majority Lenders (or all Lenders, if required under Section
11.01 hereof), and such instructions shall be binding upon all Lenders;
provided, however, that Administrative Agent shall not be required to take any
--------  -------
action which exposes Administrative Agent to personal liability or which is
contrary to any Loan Papers or applicable Law.  Administrative Agent agrees to
give to each Lender (a) notice of each notice given to it by the Borrower
pursuant to the terms of this Agreement, (b) copies of all information delivered
to the Administrative Agent in accordance with the terms of Sections 7.01, 7.02
and 7.03 hereof and (c) to promptly distribute to each applicable Lender in like
funds all amounts delivered to Administrative Agent by the Borrower for the
individual account of any Lender pro rata in accordance with the Applicable
Specified Percentage, as set forth in this Agreement.  Functions of the
Administrative Agent are administerial in nature and in no event shall the
Administrative Agent have a fiduciary or trustee relationship in respect of any
Lender by reason of this Agreement or any other Loan Paper.

     10.02.  Administrative Agent's Reliance, Etc.  Neither Administrative
Agent, nor any of its directors, officers, agents, employees, or representatives
shall be liable for any action taken or omitted to be taken by it or them under
or in connection with this Agreement or any other Loan Paper, except for its or
their own gross negligence or willful misconduct.  Without limitation of the
generality of the foregoing, Administrative Agent (a) may treat the payee of any
Note as the holder thereof until Administrative Agent receives written notice of
the assignment or transfer thereof signed by such payee and in form satisfactory
to Administrative Agent; (b) may consult with legal counsel (including counsel
for the Borrower or any of the Restricted Subsidiaries), independent public
accountants, and other experts reasonably selected by it, and shall not be
liable for any action taken or omitted to be taken in good faith by it in
accordance with the advice of such counsel, accountants, or experts; (c) makes
no warranty or representation to any Lender and shall not be responsible to any
Lender for any statements, warranties, or representations made in or in
connection with this Agreement or any other Loan Papers; (d) shall not have any
duty to ascertain or to inquire as to the performance or observance of any of
the terms, covenants, or conditions of this Agreement or any other Loan Papers
on the part of the Borrower or the Restricted Subsidiaries or to inspect the
Property (including the books and records) of the Borrower or its Subsidiaries;
(e) shall not be responsible to any Lender for the due execution, legality,
validity, enforceability, genuineness, sufficiency, or value of this Agreement,
any other Loan Papers, or any other instrument or document furnished pursuant
hereto; and (f) shall incur no liability under or in respect of this Agreement
or any other Loan Papers by acting upon any notice, consent, certificate, or
other instrument or writing believed by it to be genuine and signed or sent by
the proper party or parties.

     10.03.  Bank of America, N.A. and Affiliates.  With respect to its
Revolver A Commitment, Working Line Commitment, Swingline Commitment, Revolver B
Commitment, its Advances, and any Loan Papers, Bank of America, N.A. has the
same Rights under this Agreement as any other

                                      92
<PAGE>

Lender and may exercise the same as though it were not Administrative Agent.
Bank of America, N.A. and its Affiliates may accept deposits from, lend money
to, act as trustee under indentures of, and generally engage in any kind of
business with, any Obligor, any Restricted Subsidiary, any Affiliate thereof,
and any Person who may do business therewith, all as if Bank of America, N.A.
were not Administrative Agent and without any duty to account therefor to any
Lender, including, without limitation, the TROL Transaction.

     10.04.  Lender Credit Decision.  Each Lender acknowledges that it has,
independently and without reliance upon Administrative Agent or any other
Lender, and based on the financial statements referred to in Section 5.01(j),
Section 7.01 and Section 7.02 hereof and such other documents and information as
it has deemed appropriate, made its own credit analysis and decision to enter
into this Agreement.  Each Lender also acknowledges that it will, independently
and without reliance upon Administrative Agent or any other Lender and based on
such documents and information as it shall deem appropriate at the time,
continue to make its own credit decisions in taking or not taking action under
this Agreement and the other Loan Papers.

     10.05.  Indemnification by Lenders.  Lenders shall indemnify
Administrative Agent, pro rata in accordance with each Lender's Total Specified
Percentage, from and against any and all liabilities, obligations, losses,
damages, penalties, actions, judgments, suits, reasonable costs and expenses, or
disbursements of any kind or nature whatsoever which may be imposed on, incurred
by, or asserted against Administrative Agent in any way relating to or arising
out of any Loan Papers or any action taken or omitted by Administrative Agent
thereunder, including any negligence of Administrative Agent; provided, however,
                                                              --------  -------
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 Administrative Agent's gross negligence or willful
misconduct.  Without limitation of the foregoing, Lenders shall reimburse
Administrative Agent, pro rata in accordance with each Lender's Total Specified
Percentage, promptly upon demand for any out-of-pocket expenses (including
reasonable attorneys' fees) incurred by Administrative Agent in connection with
the preparation, execution, delivery, administration, modification, amendment,
or enforcement (whether through negotiation, legal proceedings or otherwise) of,
or legal and other advice in respect of rights or responsibilities under, the
Loan Papers.  The indemnity provided in this Section 10.05 shall survive the
termination of this Agreement.

     10.06.  Successor Administrative Agent.  Administrative Agent may resign
at any time by giving 30 days written notice thereof to Lenders and the
Borrower, and may be removed at any time with or without cause by the action of
all of the Lenders (other than Administrative Agent, if it is a Lender).  If the
Administrative Agent also then serves in the capacity of the Swingline Bank or
the Letter of Credit issuing bank, such resignation or removal shall constitute
resignation or removal of the Swingline Bank and the Administrative Agent in its
capacity of Letter of Credit issuing bank and the successor Administrative Agent
shall serve in the capacity of the Swingline Bank and the Letter of Credit
issuing bank, provided that, the Administrative Agent agrees that if it
              -------------
voluntarily resigns as Administrative Agent, the Borrower shall have up to 180
days to reissue the existing Letters of Credit.  Upon any such resignation or
removal, Majority Lenders shall have the right to appoint a successor
Administrative Agent with the prior written consent of the Borrower (which shall
not be unreasonably withheld), provided that, if there exists an Event of
                               -------------
Default that is continuing, no consent of the Borrower shall be required.  If no
successor Administrative Agent shall have been so appointed and shall have
accepted such appointment within thirty days after the retiring Administrative
Agent's giving of notice of resignation, then the retiring Administrative Agent
may,

                                      93
<PAGE>

on behalf of Lenders, appoint a successor Administrative Agent, which shall
be a commercial bank organized under the Laws of the United States of America or
of any State thereof and having a combined capital and surplus of at least
$500,000,000.  Upon the acceptance of any appointment as Administrative Agent
hereunder by a successor Administrative Agent, such successor Administrative
Agent shall thereupon succeed to and become vested with all the Rights and
duties of the retiring Administrative Agent, and the retiring Administrative
Agent shall be discharged from its duties and obligations under the Loan Papers,

provided that if the retiring or removed Administrative Agent is unable to
-------------
appoint a successor Administrative Agent, Administrative Agent shall, after the
expiration of a sixty day period from the date of notice, be relieved of all
obligations as Administrative Agent hereunder.  Notwithstanding any
Administrative Agent's resignation or removal hereunder, the provisions of this
Article shall continue to inure to its benefit as to any actions taken or
omitted to be taken by it while it was Administrative Agent under this
Agreement.

                          ARTICLE XI.  MISCELLANEOUS

    11.01.  Amendments and Waivers.  No amendment or waiver of any provision
of this Agreement or any other Loan Papers, nor consent to any departure by the
Borrower or any Obligor or Restricted Subsidiary therefrom, shall be effective

Administrative Agent with the consent of the Majority Lenders, and then any such
waiver or consent shall be effective only in the specific instance and for the
specific purpose for which given; provided, however, that no amendment, waiver,

duties of Administrative Agent under any Loan Papers, unless it is in writing
and signed by Administrative Agent in addition to the requisite number of
Lenders.  No amendment, waiver, or consent shall affect the Rights or duties of

    11.03.  Parties in Interest.  All covenants and agreements contained in
this Agreement and all other Loan Papers shall bind and inure to the benefit of

to Section 11.04 hereof.  The Borrower may not assign or transfer its Rights or
obligations hereunder without the prior written consent of each Lender.

    11.04.  Assignments and Participations.

    (a) Each Lender (an "Assignor") may assign its Rights and obligations as a
Lender under the Loan Papers to another Lender or its Bank Affiliate, or to one
or more transferees pursuant to an Assignment and Acceptance, so long as, if
such Assignee is not another Lender or a Bank Affiliate of the Assignor (i) each
assignment shall be of a constant, and not a varying percentage of all Rights
and obligations thereunder, (ii) each Assignor shall obtain in each case the
prior written consent of Administrative Agent and the Borrower, such consent of
the Borrower not to be unreasonably withheld or delayed, provided that, in the
                                                         -------------
event there exists an Event of Default that is continuing, no consent of the
Borrower shall be required to make an assignment, (iii) each Assignor shall in
each case pay a $3,500 processing fee to Administrative Agent and (iv) no such
assignment is for an amount less than $10,000,000 (unless such Lender is
assigning all of its remaining interest) and in increments of $1,000,000 (and,
if such assignment is a partial assignment, no Lender shall hold less than
$10,000,000 immediately after giving effect to any assignment unless it assigned
all of its interest).  Assignments and other transfers (except participations)
with respect to each Lender's participation in a given Letter of Credit may only
be made with the prior written consent of the Administrative Agent.  Within five
Business Days after the Borrower receives notice of any such assignment, the
Borrower shall execute and deliver to Administrative Agent, but only in exchange
for the Notes issued to Assignor, new Notes to the order of such Assignor and
its assignee in amounts equal to their respective Applicable Specified
Percentages of the Revolver A Commitment and the Revolver B Commitment (if any
exists), and/or the Working Line Commitment, or after the Conversion Date (if
any), the amount of the Working Line Loan, as applicable.  Such new Notes shall
be dated the effective date of the assignment.  It is specifically acknowledged
and agreed that on and after the effective date of each assignment, the assignee
shall be a party hereto and shall have the Rights and obligations of a Lender
under the Loan Papers.

    (b) Each Lender may sell participations to one or more Persons in all or any
of its Rights and obligations under the Loan Papers; provided, however, that (i)
                                                     --------  -------
such Lender's obligations under the Loan Papers shall remain unchanged, (ii)
such Lender shall remain solely responsible to the other parties hereto for the
performance of such obligations, (iii) such Lender shall remain the holder of
its Notes for all purposes of the Loan Papers, (iv) the participant shall be
granted the Right to vote on or consent to only those matters described in
Sections 11.01(a), (b), (c), (d) and (e) hereof, (v) Obligors, the Restricted
Subsidiaries, the Administrative Agent, and other Lenders shall continue to deal
solely and directly with such Lender in connection with their respective Rights
and obligations under the Loan Papers and (vi) no such participation is for an
amount less than $5,000,000.

                                      97
<PAGE>

    (c) Any Lender may, in connection with any assignment or participation, or
proposed assignment or participation, disclose to the assignee or participant,
or proposed assignee or participant, any information relating to the Borrower
and its Subsidiaries furnished to such Lender by or on behalf of the Borrower
and its Subsidiaries, subject to the provisions of Section 11.15 hereof.

    (d) Notwithstanding any other provision set forth in this Agreement, (i) any
Lender may at any time create a security interest in all or any portion of its
Rights under this Agreement (including, without limitation, the Advances owing
to it and the Notes held by it) in favor of any Federal Reserve Bank in
accordance with Regulation A of the Board of Governors of the Federal Reserve
System and (ii) no participant of any Lender may further assign or participate
any of its interest in the Loan Papers to any Person (except as may be required
by Law or a Tribunal having authority over such participant).

    11.05.  Sharing of Payments.  If, after and during the continuance of any
Event of Default,  any Lender shall obtain any payment (whether voluntary,
involuntary, through the exercise of any Right of set-off, or otherwise) on
account of its Advances in excess of its pro rata share of payments made by the
Borrower in accordance with such Lender's Total Specified Percentage (except
payments to the Swingline Bank made to repay Swingline Advances), such Lender
shall forthwith purchase participations in Advances made by the other Lenders as
shall be necessary to share the excess payment pro rata in accordance with each
Lender's Total Specified Percentage with each of them; provided, however, that
                                                       --------  -------
if any of such excess payment is thereafter recovered from the purchasing
Lender, its purchase from each Lender shall be rescinded and each Lender shall
repay the purchase price to the extent of such recovery together with a pro rata
share of any interest or other amount paid or payable by the purchasing Lender
in respect of the total amount so recovered.  The Borrower agrees that any
Lender so purchasing a participation from another Lender pursuant to this
Section 11.05 may, to the fullest extent permitted by Law, exercise all its
Rights of payment (including the Right of set-off) with respect to such
participation as fully as if such Lender were the direct creditor of the
Borrower in the amount of such participation.

    11.06.  Right of Set-off.  Upon the occurrence and during the continuance
of any Event of Default, each Lender is hereby authorized (after prior written
notice to the Administrative Agent) at any time and from time to time, to the
fullest extent permitted by Law, to set-off and apply any and all deposits
(general or special, time or demand, provisional or final) at any time held and
other indebtedness at any time owing by such Lender to or for the credit or the
account of the Borrower or any of its Restricted Subsidiaries against any and
all of the obligations of the Borrower now or hereafter existing under this
Agreement and the other Loan Papers, whether or not Administrative Agent or any
Lender shall have made any demand under this Agreement or the other Loan Papers,
and even if such obligations are unmatured.  Each Lender shall promptly notify
the Borrower after any such set-off and application, provided that the failure
                                                     -------------
to give such notice shall not affect the validity of such set-off and
application.  The Rights of each Lender under this Section 11.06 are in addition
to other Rights (including, without limitation, other Rights of set-off) which
such Lender may have.

    11.07.  Costs, Expenses, and Taxes.

                                      98
<PAGE>

    (a) Notwithstanding anything to the contrary in the Loan Papers, the
Borrower agrees to pay on demand (i) all reasonable out of pocket costs and
expenses of Administrative Agent in connection with the preparation and
negotiation of all Loan Papers, including without limitation the reasonable fees
and out-of-pocket expenses of Special Counsel, FCC counsel, PUC counsel and
local counsel, as appropriate, (ii) all costs and expenses (including reasonable
attorneys' fees and expenses) of Administrative Agent in connection with any
interpretation, grant and perfection of any Lien, modification, amendment,
waiver, release of any Loan Papers, restructuring or work-out and (iii) all
costs and expenses (including reasonable attorneys' fees and expenses) of
Administrative Agent in connection with any collection of any portion of the
Obligations or the enforcement of any Loan Papers during the continuance of an
Event of Default.

    (b) In addition, notwithstanding anything to the contrary in the Loan
Papers, the Borrower shall pay any and all stamp, debt, and other Taxes payable
or determined to be payable in connection with any payment hereunder to
Administrative Agent, Arranging Agents or any Lender (but specifically excluding
any participant) (other than Taxes on the overall net income of Administrative
Agent or any Lender or franchise Taxes or Taxes on capital or capital receipts
of Administrative Agent or any Lender), or the execution, delivery, or
recordation of any Loan Papers, and agrees to save Administrative Agent and each
Lender harmless from and against any and all liabilities with respect to, or
resulting from any delay in paying or omission to pay any Taxes in accordance
with this Section 11.07, including any penalty, interest, and expenses relating
thereto.  All payments by the Borrower or any Restricted Subsidiary of the
Borrower under any Loan Papers shall be made free and clear of and without
deduction for any present or future Taxes (other than Taxes on the overall net
income of Administrative Agent or any Lender of any nature now or hereafter
existing, levied, or withheld, or franchise Taxes or Taxes on capital or capital
receipts of Administrative Agent or any Lender), including all interest,
penalties, or similar liabilities relating thereto.  If the Borrower shall be
required by Law to deduct or to withhold any Taxes from or in respect of any
amount payable hereunder (i) the amount so payable shall be increased to the
extent necessary so that, after making all required deductions and withholdings
(including Taxes on amounts payable to Administrative Agent or any Lender
pursuant to this sentence), Administrative Agent or any Lender receives an
amount equal to the sum it would have received had no such deductions or
withholdings been made, (ii) the Borrower shall make such deductions or
withholdings, and (iii) the Borrower shall pay the full amount deducted or
withheld to the relevant taxing authority in accordance with applicable Law.
Without prejudice to the survival of any other agreement of the Borrower
hereunder, the agreements and obligations of the Borrower contained in this
Section 11.07 shall survive the execution of this Agreement, termination of the
Commitment, repayment of the Obligations, satisfaction of each agreement
securing or assuring the Obligations and termination of this Agreement and each
other Loan Paper.

    11.08.  Rate Provision.  It is not the intention of any party to any Loan
Papers to make an agreement violative of the Laws of any applicable jurisdiction
relating to usury.  In no event shall any Obligor, Restricted Subsidiary or any
other Person be obligated to pay any amount in excess of the Maximum Amount.  If
Administrative Agent or any Lender ever receives, collects or applies, as
interest, any such excess, such amount which would be excessive interest shall
be deemed a partial repayment of principal and treated hereunder as such; and if
principal is paid in full, any remaining excess shall be paid to the Borrower or
the other Person entitled thereto.  In determining whether or not the interest
paid or payable, under any specific contingency, exceeds the Maximum Amount,
each Obligor, Restricted Subsidiary, Administrative Agent and each Lender shall,
to the maximum extent permitted under Applicable Laws, (a) characterize any
nonprincipal payment as an expense, fee or

                                      99
<PAGE>

premium rather than as interest, (b) exclude voluntary prepayments and the
effect thereof, and (c) amortize, prorate, allocate and spread in equal parts,
the total amount of interest throughout the entire contemplated term of the
Obligations so that the interest rate is uniform throughout the entire term of
the Obligations; provided that if the Obligations are paid and
                 ------------
performed in full prior to the end of the full contemplated term thereof, and if
the interest received for the actual period of existence thereof exceeds the
Maximum Amount, Administrative Agent or Lenders, as appropriate, shall refund to
the Borrower the amount of such excess or credit the amount of such excess
against the total principal amount owing, and, in such event, to the extent
permitted by Applicable Law, neither Administrative Agent nor any Lender shall
be subject to any penalties provided by any Laws for contracting for, charging
or receiving interest in excess of the Maximum Amount. This Section 11.08 shall
control every other provision of all agreements among the parties to the Loan
Papers pertaining to the transactions contemplated by or contained in the Loan
Papers.

    11.09.  Severability.  If any provision of any Loan Paper is held to be
illegal, invalid, or unenforceable under present or future Laws during the term
thereof, such provision shall be fully severable, the appropriate Loan Paper
shall be construed and enforced as if such illegal, invalid, or unenforceable
provision had never comprised a part thereof, and the remaining provisions
thereof shall remain in full force and effect and shall not be affected by the
illegal, invalid, or unenforceable provision or by its severance therefrom.
Furthermore, in lieu of such illegal, invalid, or unenforceable provision there
shall be added automatically as a part of such Loan Paper a legal, valid, and
enforceable provision substantially similar in terms to the illegal, invalid, or
unenforceable provision as may be possible.

    11.10.  Exceptions to Covenants.  No Obligor or Restricted Subsidiary
shall be deemed to be permitted to take any action or to fail to take any action
that is permitted as an exception to any covenant in any Loan Papers, or that is
within the permissible limits of any covenant, if such action or omission would
result in a violation of any other covenant in any Loan Papers.

    11.11.  Counterparts.  This Agreement and the other Loan Papers may be
executed in any number of counterparts with different parties signing on
different counterparts, all of which taken together shall constitute one and the
same instrument.  In making proof of any such agreement, it shall not be
necessary to produce or account for any counterpart other than one signed by the
party against which enforcement is sought.

    11.12.  GOVERNING LAW; WAIVER OF JURY TRIAL.

    (a) THIS AGREEMENT AND ALL OTHER LOAN PAPERS SHALL BE DEEMED TO BE CONTRACTS
MADE IN NEW YORK, NEW YORK, AND SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE
WITH THE LAWS OF THE STATE OF NEW YORK, AND THE UNITED STATES OF AMERICA.
WITHOUT EXCLUDING ANY OTHER JURISDICTION, THE BORROWER AGREES TO SUBMIT ITSELF
TO THE JURISDICTION OF THE FEDERAL COURTS OF NEW YORK LOCATED IN NEW YORK, NEW
YORK FOR PROCEEDINGS IN CONNECTION HEREWITH.  TO THE MAXIMUM EXTENT PERMITTED BY
LAW, THE BORROWER, THE ADMINISTRATIVE AGENT AND EACH LENDER  HEREBY WAIVES ANY
RIGHT THAT IT MAY HAVE TO A TRIAL BY JURY OF ANY DISPUTE (WHETHER A CLAIM IN
TORT, CONTRACT, EQUITY, OR OTHERWISE) ARISING UNDER OR RELATING TO THIS
AGREEMENT, THE OTHER LOAN PAPERS, OR ANY RELATED MATTERS, AND

                                      100
<PAGE>

AGREES THAT ANY SUCH DISPUTE SHALL BE TRIED BEFORE A JUDGE SITTING WITHOUT A
JURY.

    (b) THE BORROWER, THE ADMINISTRATIVE AGENT AND EACH LENDER HEREBY WAIVES
PERSONAL SERVICE OF ANY LEGAL PROCESS UPON IT.  THE BORROWER, THE ADMINISTRATIVE
AGENT AND EACH LENDER AGREES THAT SERVICE OF PROCESS MAY BE MADE UPON IT BY
REGISTERED MAIL (RETURN RECEIPT REQUESTED) DIRECTED TO THE BORROWER, THE
ADMINISTRATIVE AGENT OR EACH SUCH LENDER, RESPECTIVELY, AT ITS ADDRESS
DESIGNATED FOR NOTICE UNDER THIS AGREEMENT.   NOTHING IN THIS SECTION 11.12
SHALL AFFECT THE RIGHT OF ANY PARTY TO SERVE LEGAL PROCESS IN ANY OTHER MANNER
PERMITTED BY LAW.

    11.13.  ENTIRE AGREEMENT.  THIS AGREEMENT AND THE OTHER LOAN PAPERS
REPRESENT THE FINAL AGREEMENT BETWEEN THE PARTIES AND MAY NOT BE CONTRADICTED BY
EVIDENCE OF PRIOR, CONTEMPORANEOUS OR SUBSEQUENT ORAL AGREEMENT OF THE PARTIES.
THERE ARE NO UNWRITTEN ORAL AGREEMENTS BETWEEN THE PARTIES.  THIS AGREEMENT
SUPERSEDES AND REPLACES IN ITS ENTIRETY THE COMMITMENT LETTER AGREEMENT DATED
FEBRUARY 8, 2000 INCLUDING, WITHOUT LIMITATION, THE SUMMARY OF TERMS AND
CONDITIONS DATED FEBRUARY 8, 2000.

    11.14.  Release of Conditional Early Release Unlimited Guaranty. At such
time as (i) there exists no Default under Section 9.01(a) hereof, (ii) there
exists no Event of Default and (iii) the Senior Unsecured Debt Rating is BBB- or
Baa3 or better, the Guarantor shall be immediately and automatically released
from its obligations under the Conditional Early Release Unlimited Guaranty, and
the Administrative Agent shall, and the Arranging Agents and the Lenders hereby
authorize the Administrative Agent to, promptly take all action and execute such
documents to release the Guarantor from its obligations under the Conditional
Early Release Unlimited Guaranty in full, and return the Conditional Early
Release Unlimited Guaranty to the Guarantor.

    11.15.  Confidentiality. Each Lender agrees to keep information obtained
by it pursuant to the terms hereof or the terms of any other Loan Paper that is
not otherwise publicly available ("Confidential Information") confidential in
accordance with such Lender's customary procedures for handling confidential
information of this nature and in accordance with safe and sound banking
practices and agrees that it will only use such Confidential Information in
connection with the transactions contemplated by this Agreement and not disclose
any of such Confidential Information other than (a) to such Lenders and its
Affiliates' (other than an Affiliate which is a competitor of the Borrower or
its Subsidiaries) employees, counsel (in-house and outside), accountants,
consultants, representatives, professional advisors and agents so long as such
Person is advised of the confidentiality of such Confidential Information and
the limitation on its use under this Section 11.15, needs to have knowledge of
such Confidential Information for such limited use, and, if such Person is not
such Lenders' or its Affiliates' employee, counsel (in-house and outside),
accountant consultant,  professional advisor or agent, such Person has executed
a confidentiality undertaking in favor of the Borrower substantially upon the
terms of this Section 11.15 before such Confidential Information is disclosed to
such Person, (b) to regulatory officials, and in order to comply with any
Applicable Law, or other law, regulation or judicial order, or as requested or
required by bank regulators or auditors or other governmental authorities or
Tribunals, (c) as reasonably deemed

                                      101
<PAGE>

necessary in connection with any investigation, legal process or litigation, or
(d) to assignees or participants or proposed assignees or proposed participants
of all or any part of this credit facility so long as such Person has executed a
confidentiality undertaking in favor of the Borrower substantially upon the
terms of this Section 11.15 before such Confidential Information is disclosed to
such Person. The failure of any Lender to comply with the provisions of this
Section 11.15 shall not affect the Obligations, or the obligation of the
Borrower to comply with the terms of this Agreement and the other Loan Papers,
or the validity of any assignment or participation granted pursuant to the terms
of this Agreement. Each Lender shall be responsible for any breach of the
provisions of this Section 11.15 or unauthorized disclosure of such Confidential
Information by any of its or its Affiliates' employees, counsel (in-house and
outside), accountants, consultants, representatives, professional advisors and
agents. Each Lender shall take customary precautions to prevent Confidential
Information from being disclosed to its employees or employees of any Affiliate
who are equity analysts or Persons involved in publication of research in
connection with the Borrower or any of the Borrower's Subsidiaries or any of
their respective securities.

    11.16.  Amendment and Restatement.  This Agreement is an amendment and
restatement of the Original Credit Agreement by Majority Lenders in accordance
with the terms of Section 11.01 of the Original Credit Agreement, and, as such,
except for the "Obligation" as defined in the Original Credit Agreement (which
shall survive, be renewed and restated by the terms of this Agreement), all
terms and provisions of this Agreement supersede in their entirety the terms and
provisions of the Original Credit Agreement.  The Conditional Early Release
Unlimited Guaranty shall remain valid, binding and enforceable.  All references
in any Loan Paper to the "Credit Agreement" shall hereafter be deemed to be
references to this Agreement.  All provisions of each Loan Paper shall remain in
full force and effect, and such provisions are hereby ratified and confirmed,
regardless of whether any such Loan Paper was executed prior to the Amendment
and Restatement Closing Date.

    11.17.  Option Date and Extension.  The parties hereto acknowledge and
agree that on and as of the Option Date, the Borrower has exercised the
Extension Option, and the Working Line Loan has been extended for an additional
364 days in accordance with the terms of Section 2.16(a) hereof and the other
terms and provisions of this Agreement, and the Lenders' Working Line Specified
Percentages of the Working Line Loan, as so extended, shall be as set forth on
the signature pages hereto.

Borrower's requesting that an Advance (including a Refinancing Advance) not be
made on the date specified in the Borrowing Notice.

     2.03.  Evidence of Debt for Borrowed Money.  The Advances made by each
Lender under the Loans shall be evidenced by a Note in the amount of such
Lender's Specified Percentage of the Commitment.  The Administrative Agent's and
each Lender's records shall be presumptive evidence as to amounts owed
Administrative Agent and such Lender under the Notes and this Agreement.

     2.04.  Optional Prepayments.

                                      28
<PAGE>

     (a) The Borrower may, upon at least two Business Days prior written notice
to Administrative Agent stating the proposed date and aggregate principal amount
of the prepayment, prepay the outstanding principal amount of any Advances in
whole or in part, together with accrued interest to the date of such prepayment
on the principal amount of LIBOR Advances prepaid without premium or penalty
other than any Consequential Loss; provided, however, that in the case of a
                                   --------  -------
prepayment of a Base Advance, the notice of prepayment may be given by telephone
by 12:00 p.m. central standard time on the date of prepayment.  Each partial
prepayment shall, in the case of Base Advances under the Loans, be in an
aggregate principal amount of not less than $100,000 or a larger integral
multiple of $50,000 in excess thereof and, in the case of LIBOR Advances under
the Loans, be in an aggregate principal amount of not less than $500,000 or a
larger integral multiple of $100,000 in excess thereof.  If any notice of
prepayment is given, the principal amount stated therein, together with accrued
interest on the amount of LIBOR Advances prepaid and the amount, if any, due
under Section 2.12 and Section 2.14 hereof, shall be due and payable on the date
specified in such notice unless the Borrower revokes its notice, provided that,
                                                                 -------------
if the Borrower revokes its notice of prepayment prior to such date specified,
the Borrower shall reimburse the Administrative Agent for the account of all
Lenders for all Consequential Losses suffered by each Lender as a result of the
Borrower's failure to prepay.  A certificate of each Lender claiming
compensation under this Section 2.04(a), setting forth in reasonable detail the
calculation of the additional amount or amounts to be paid to it hereunder shall
be presumptive evidence of the validity of such claim.

     (b) All prepayments made pursuant to this Section 2.04 shall be first
applied to Base Advances then to LIBOR Advances, all without premium or penalty,
except the Borrower must pay together with any such prepayments, any
Consequential Losses.

     2.05.  Mandatory Prepayments.

     (a) Asset Sales and Investments.  To the extent that the Borrower or any of
the Restricted Subsidiaries consummates any Disposition of any asset or any of
its Properties except (i) Dispositions consummated in accordance with the terms
of Section 7.05(a)(i) hereof and (ii) if there exists no Default or Event of
Default both before and after giving effect to any such Disposition,
Dispositions consummated in accordance with the other terms and provisions of
Section 7.05(a) hereof (other than Section 7.05(a)(i) hereof), then the Borrower
shall immediately use or cause to be used 100% of the Net Proceeds of any such
transaction received by or allocated to the Borrower or such Restricted
Subsidiary as the case may be, to repay the Obligations under the Loans except
to the extent that such Net Proceeds are ultimately reinvested within a 12 month
period after any such asset Disposition, in assets used in the
Telecommunications Business, including, without limitation, the internet,
internet protocol, web hosting or electronic commerce of the Borrower or any of
the Wholly Owned Restricted Subsidiaries, acquisitions permitted under Section
7.18 hereof or Investments permitted under Section 7.04 hereof.

     (b) Mandatory Prepayments, Generally.  All prepayments made pursuant to
this Section 2.05 shall be first applied to Base Advances then to LIBOR
Advances, all without premium or penalty, except the Borrower must pay together
with such prepayments, any accrued interest on LIBOR Advances repaid by such
prepayments and any Consequential Losses.

     2.06.  Repayment.

                                      29
<PAGE>

     (a) LIBOR Advances.  The principal amount of each LIBOR Advance is due and
payable on the last day of the applicable Interest Period, which principal
payment may be made by means of a Refinancing Advance in accordance with the
terms of Section 2.09 hereof (and subject to the other provisions of this
Agreement).

     (b) Commitment Reduction.  On the date of a reduction of the Commitment
pursuant to Section 2.11 hereof, the aggregate amount of outstanding Advances in
excess of the Commitment as reduced shall in each case be immediately due and
payable.  Each such principal repayment may not be made by means of Refinancing
Advances.

     (c) Maturity Date.  All outstanding Advances under the Loans and all other
Obligations shall be due and payable in full on the Maturity Date.

     (d) Repayments, Generally.  Any repayments made pursuant to this Section
shall be without premium or penalty, except the Borrower must pay together with
any such prepayments, any Consequential Losses.  Repayment of Advances shall
be applied to Base Advances first, and then to LIBOR Advances.

     2.07.  Interest.  Subject to Section 2.08 and Section 10.08 hereof, the
Borrower shall pay interest on the unpaid principal amount of each Advance from
the date of such Advance until such principal shall be paid in full, at either
the Base Rate or the LIBOR Rate, as set forth in subsection (a) or (b) below, as
selected by the Borrower in accordance with Section 2.02 hereof and as follows:

           (a) Base Advances.  Base Advances shall bear interest at a rate per
     annum equal to the Base Rate as in effect from time to time.  If the amount
     of interest payable in respect of any interest computation period is
     reduced to the Highest Lawful Rate and the amount of interest payable in
     respect of any subsequent interest computation period would be less than
     the Maximum Amount, then the amount of interest payable in respect of such
     subsequent interest computation period shall be automatically increased to
     the Maximum Amount; provided that at no time shall the aggregate amount by
                         -------------
     which interest paid has been increased pursuant to this sentence exceed the
     aggregate amount by which interest has been reduced pursuant to this
     sentence.

           (b) LIBOR Advances.  LIBOR Advances shall bear interest at the rate
     per annum equal to the LIBOR Rate applicable to such Advance.

           (c) Payment Dates.  Accrued and unpaid interest on Base Advances
     shall be paid quarterly in arrears on each Quarterly Date and on the
     Maturity Date. Accrued and unpaid interest in respect of each LIBOR Advance
     shall be paid on the last day of the appropriate Interest Period, on the
     Maturity Date and on the date of any prepayment or repayment of such
     Advance; provided, however, that if any Interest Period for a LIBOR Advance
              -----------------
     exceeds three months, interest shall also be paid on the date which falls
     three months after the beginning of such Interest Period and each three
     months thereafter until such Interest Period expires.

     2.08.  Default Interest.  During the continuation of any Event of
Default, the Borrower shall pay, on demand, interest (after as well as before
judgment to the extent permitted by Law) on the principal amount of all Advances
outstanding and on all other Obligations due and unpaid hereunder at a per annum
rate equal to (a) until, for each LIBOR Advance in existence at such time, the

                                      30
<PAGE>

expiration of the applicable Interest Period relating to such LIBOR Advance, the
lesser of (i) the Highest Lawful Rate and (ii) the applicable LIBOR Rate for
such LIBOR Advance plus 2% and (b) for each Base Advance, the lesser of the (i)
the Highest Lawful Rate and (ii) the Base Rate plus 2%.  LIBOR Advances shall
not be available for selection by the Borrower during the continuance of an
Event of Default.

     2.09.  Continuation and Conversion Elections.

     (a) The Borrower may upon irrevocable written notice to Administrative
Agent and subject to the terms of this Agreement:

               (i)  elect to convert, on any Business Day, all or any portion of
     outstanding Advances which are Base Advances (in an aggregate amount not
     less than $500,000 or an integral multiple of $100,000 in excess thereof)
     into LIBOR Advances; or

               (ii) elect to convert at the end of any Interest Period therefor,
     all or any portion of outstanding Advances which are LIBOR Advances
     comprised in the same Borrowing (in an aggregate amount not less than
     $100,000 or an integral multiple of $50,000 in excess thereof) into Base
     Advances; or

               (iii) elect to continue, at the end of any Interest Period
     therefor, any Advances which are LIBOR Advances;

provided, however, that if the aggregate amount of outstanding LIBOR Advances
--------  -------
comprised in the same Borrowing shall have been reduced as a result of any
payment, prepayment or conversion of part thereof to an amount less than
$500,000, the LIBOR Advances comprised in such Borrowing shall automatically
convert into Base Advances at the end of each respective Interest Period.

     (b) The Borrower shall deliver a notice of conversion or continuation (a
"Conversion or Continuation Notice"), in substantially the form of Exhibit D
                                                                   ---------
hereto, to Administrative Agent not later than (i) 12:00 p.m. central standard
time three Business Days prior to the proposed date of conversion or
continuation, if the Advances (or any portion of either thereof) are to be
converted into or continued as LIBOR Advances; and (ii) 12:00 p.m. central
standard time on the Business Day of the proposed conversion, if the Advances
(or any portion thereof) are to be converted into Base Advances.

     Each such Conversion or Continuation Notice shall be by telecopy or
telephone, promptly confirmed by letter, specifying therein:

               (i)   the proposed date of conversion or continuation;

               (ii)  the aggregate amount of Advances to be converted or
     continued;

               (iii) the nature of the proposed conversion or continuation; and

               (iv)  the duration of the applicable Interest Period.

     (c) If, upon the expiration of any Interest Period applicable to LIBOR
Advances, the Borrower shall have failed to select a new Interest Period to be
applicable to such LIBOR Advances

                                      31
<PAGE>

or if an Event of Default shall then have occurred and be continuing, the
Borrower shall be deemed to have elected to convert such LIBOR Advances into
Base Advances effective as of the expiration date of such current Interest
Period.

     (d) Notwithstanding any other provision contained in this Agreement, after
giving effect to any conversion or continuation of any Advances, there shall not
be outstanding Advances with more than seven different Interest Periods.

     2.10.  Fees.

     (a) Commitment Fee.  Subject to Section 10.08 hereof, the Borrower shall
pay to Administrative Agent for the account of Lenders pro rata in accordance
with each Lender's Specified Percentage, a commitment fee equal to the
Applicable Commitment Fee Percentage per annum on the average daily amount of
the difference between the Commitment and the sum of all outstanding Advances
(the "Commitment Fee").  The Commitment Fee set forth above shall be payable in
arrears on each Quarterly Date commencing with the first Quarterly Date after
the Closing Date, and continuing until the Maturity Date.

     (b) Other Fees.  Borrower shall pay to Administrative Agent and the Lenders
such other fees as set forth in any Fee Letter addressed to the Administrative
Agent or any Lender.

     2.11.  Reduction of Commitments.

     (a) Mandatory Termination of the Commitment.  The Commitment shall
automatically be reduced to zero and terminate on the Maturity Date.

     (b) Mandatory Reduction of Commitment Due to Asset Sales.  The Commitment
shall be reduced immediately and automatically in an amount equal to any amount
that would be required by Section 2.05(a) hereof to prepay the Loans (regardless
of whether there are any outstanding Obligations under the Loans)  as a result
of any Dispositions of assets and Properties of the Borrower or any of the
Restricted Subsidiaries (this provision in and of itself not constituting
permission to effectuate any asset Dispositions), provided that (i) so long as
                                                  -------------
there exists no Event of Default both immediately before and after giving effect
to such asset Dispositions and both immediately before and after any permitted
reinvestment and (ii) if a Default exists after giving effect to any such
Disposition, so long as such Default does not ultimately become an Event of
Default, the Commitment shall not be automatically and immediately reduced if
the Borrower in good faith intends to reinvest, and such proceeds are ultimately
reinvested within a 12 month period after any such asset Disposition, in assets
used in the Telecommunications Business, including, without limitation, the
internet, internet protocol, web hosting or electronic commerce of the Borrower
or any of the Wholly Owned Restricted Subsidiaries, acquisitions permitted under
Section 7.18 hereof or Investments permitted under Section 7.04 hereof.

     (c) Specified Change of Control.  If any Specified Change of Control shall
have occurred and such Specified Change of Control has caused a Repayment Event,
the Commitment shall immediately and automatically be reduced to zero.

     (d) Voluntary Commitment Reductions.  The Borrower may from time to time,
upon notice to Administrative Agent not later than 1:00 p.m., three Business
Days in advance, terminate

                                      32
<PAGE>

in whole or reduce in part the Commitment, as designated by the Borrower;
provided, however, that the Borrower shall pay the accrued interest and the
-----------------
applicable accrued Commitment Fee on the amount of such reduction and all
amounts due, and any partial reduction shall be in an aggregate amount which is
an integral multiple of $5,000,000.

     (f) Commitment Reduction and Repayments, Generally.  To the extent
outstanding Advances exceed the Commitment after any reduction thereof, the
Borrower shall repay, on the date of such reduction, any such excess amount and
all accrued interest thereon, the applicable Commitment Fee on the amount of
such reduction and all amounts due.  Once reduced or terminated, the Commitment
may not be increased or reinstated.  No reduction of the Commitment, either
voluntary or mandatory shall relieve or alter the mandatory reduction and
termination of the Commitment pursuant to this Section 2.11.

     2.12.  Funding Losses.  The Borrower may prepay the outstanding principal
balance of any Advance, in full at any time or in part from time to time in
accordance with the terms of Section 2.04 hereof, provided, that as a condition
                                                  --------
precedent to the Borrower's right to make, and any Lender's obligation to
accept, any such prepayment, each such prepayment shall be in the amount of 100%
of the principal amount to be prepaid, plus, with respect to LIBOR Advances,
accrued unpaid interest thereon to the date of prepayment, plus any other sums
which have become due to Administrative Agent and Lenders under the Loan Papers
on or before the prepayment date but have not been paid, plus (subject to
Section 10.08 hereof) any Consequential Loss.

     The Borrower agrees that each Lender is not obligated to actually reinvest
the amount prepaid in any specific obligation as a condition to receiving any
Consequential Loss, or otherwise.

     2.13.  Computations and Manner of Payments.

     (a) The Borrower shall make each payment hereunder and under the other Loan
Papers not later than 1:00 p.m. on the day when due in same day funds (by wire
transfer or otherwise) to Administrative Agent, for the account of Lenders
unless otherwise specifically provided herein, at Administrative Agent's office
at Bank of America Plaza, 901 Main Street, Dallas, Texas  75202, referencing
Qwest Communications International Inc.  No later than the end of each day when
each payment hereunder is made, the Borrower shall notify Loan Operations at
(214) 508-9192 or such other Person as Administrative Agent may from time to
time specify.

     (b) Unless Administrative Agent shall have received notice from the
Borrower prior to the date on which any payment is due hereunder that the
Borrower will not make payment in full, Administrative Agent may assume that
such payment is so made on such date and may, in reliance upon such assumption,
make distributions to Lenders.  If and to the extent the Borrower shall not have
made such payment in full, each Lender shall repay to Administrative Agent
forthwith on demand the applicable amount distributed, together with interest
thereon at the Federal Funds Rate, from the date of distribution until the date
of repayment.  The Borrower hereby authorizes each Lender, if and to the extent
payment is not made when due hereunder, to charge the amount so due against any
account of the Borrower with such Lender.

     (c) Subject to Section 10.08 hereof, interest on LIBOR Advances under the
Loan Papers shall be calculated on the basis of actual days elapsed but computed
as if each year consisted of 360 days.  Subject to Section 10.08 hereof,
interest on Base Advances, the Commitment Fee and other

                                      33
<PAGE>

amounts due under the Loan Papers shall be calculated on the basis of actual
days elapsed but computed as if each year consisted of 365 or 366 days, as
applicable. Such computations shall be made including the first day but
excluding the last day occurring in the period for which such interest, payment
or Commitment Fee is payable. Each determination by Administrative Agent or a
Lender of an interest rate, fee or commission hereunder shall be presumptive
evidence of the validity of such claim. All payments under the Loan Papers shall
be made in United States dollars, and without setoff, counterclaim, or other
defense.

     (d) Whenever any payment to be made hereunder or under any other Loan
Papers shall be stated to be due on a day other than 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 interest or fees, if applicable;
provided, however, if such extension would cause payment of interest on or
--------  -------
principal of LIBOR Advances to be made in the next following calendar month,
such payment shall be made on the next preceding Business Day.

     (e) Reference to any particular index or reference rate for determining any
applicable interest rate under this Agreement is for purposes of calculating the
interest due and is not intended as and shall not be construed as requiring any
Lender to actually obtain funds for any Advance at any particular index or
reference rate.

     2.14.  Yield Protection; Changed Circumstances.

     (a   If any Lender determines that either (i) the adoption of any
Applicable Law, rule, regulation or guideline regarding capital adequacy and
applicable to commercial banks or financial institutions generally or any change
therein, or any change, after the date hereof, in the interpretation or
administration thereof by any Tribunal, central bank or comparable agency
charged with the interpretation or administration thereof, or (ii) compliance by
any Lender (or Lending Office of any Lender) with any request or directive
applicable to commercial banks or financial institutions generally regarding
capital adequacy (whether or not having the force of law) of any such authority,
central bank or comparable agency has the effect of reducing the rate of return
on such Lender's capital as a consequence of its obligations hereunder to a
level below that which such Lender could have achieved but for such adoption,
change or compliance (taking into consideration such Lender's policies with
respect to capital adequacy) by an amount reasonably deemed by such Lender to be
material, then from time to time, within fifteen days after demand by such
Lender, the Borrower shall pay to such Lender such additional amount or amounts
as will adequately compensate such Lender for such reduction.  Each Lender will
notify the Borrower of any event occurring after the date of this Agreement
which will entitle such Lender to compensation pursuant to this Section 2.14(a)
as promptly as practicable after such Lender obtains actual knowledge of such
event; provided, no Lender shall be liable for its failure or the failure of any
       --------
other Lender to provide such notification.  A certificate of such Lender
claiming compensation under this Section 2.14(a), setting forth in reasonable
detail the calculation of the additional amount or amounts to be paid to it
hereunder shall be presumptive evidence of the validity of such claim.  If such
Lender demands compensation under this Section 2.14(a), the Borrower may at any
time, on at least five Business Days' prior notice to such Lender (i) repay in
full the then outstanding principal amount of LIBOR Advances, of such Lender,
together with accrued interest thereon, or (ii) convert the LIBOR Advances to
Base Advances in accordance with the provisions of this Agreement; provided,
                                                                   --------
however, that the Borrower shall be liable for the Consequential Loss arising
-------
pursuant to those actions.

                                      34
<PAGE>

     (b) If, after the date hereof, any Tribunal, central bank or other
comparable authority, at any time imposes, modifies or deems applicable any
reserve (including, without limitation, any imposed by the Board of Governors of
the Federal Reserve System), special deposit or similar requirement against
assets of, deposits with or for the amount of, or credit extended by, any
Lender, or imposes on any Lender any other condition affecting a LIBOR Advance,
the Notes, or its obligation to make a LIBOR Advance, and the result of any of
the foregoing is to increase the cost to such Lender of making or maintaining
LIBOR Advances, or to reduce the amount of any sum received or receivable by
such Lender under this Agreement or under the Notes by an amount deemed by such
Lender, to be material, then, within five days after demand by such Lender, the
                        ----
Borrower shall pay to such Lender such additional amount or amounts as will
compensate such Lender for such increased cost or reduction.  Each Lender will
(i) notify the Borrower of any event occurring after the date of this Agreement
that entitles such Lender to compensation pursuant to this Section 2.14(b), as
promptly as practicable after such Lender obtains actual knowledge of the event;
provided, no Lender shall be liable for its failure or the failure of any other
--------
Lender to provide such notification and (ii) use good faith and reasonable
efforts to designate a different Lending Office for LIBOR Advances, of such
Lender if the designation will avoid the need for, or reduce the amount of, the
compensation and will not, in the sole opinion of such Lender, be
disadvantageous to such Lender.  A certificate of such Lender claiming
compensation under this Section 2.14(b), setting forth in reasonable detail the
computation of the additional amount or amounts to be paid to it hereunder shall
be presumptive evidence of the validity of such claim.  If such Lender demands
compensation under this Section 2.14(b), the Borrower may at any time, on at
least five Business Days' prior notice to such Lender (i) repay in full the then
outstanding principal amount of LIBOR Advances, of such Lender, together with
accrued interest thereon, or (ii) convert the LIBOR Advances to Base Advances in
accordance with the provisions of this Agreement; provided, however, that the
                                                  --------  -------
Borrower shall be liable for the Consequential Loss arising pursuant to those
actions.

     (c) Notwithstanding any other provision of this Agreement, if the
introduction of or any change in or in the interpretation or administration of
any Law shall make it unlawful, or any central bank or other Tribunal shall
assert that it is unlawful, for a Lender to perform its obligations hereunder to
make LIBOR Advances or to continue to fund or maintain LIBOR Advances hereunder,
then, on notice thereof and demand therefor by such Lender to the Borrower, (i)
each LIBOR Advance will automatically, upon such demand, convert into a Base
Advance and (ii) the obligation of such Lender to make, or to convert Advances
into, LIBOR Advances shall be suspended until such Lender notifies
Administrative Agent and the Borrower that such Lender has determined that the
circumstances causing such suspension no longer exist.

     (d) Upon the occurrence and during the continuance of any Default or Event
of Default, (i) each LIBOR Advance will automatically, on the last day of the
then existing Interest Period therefor, convert into a Base Advance and (ii) the
obligation of each Lender to make, or to convert Advances into, LIBOR Advances
shall be suspended.

     (e) If any Lender notifies Administrative Agent that the LIBOR Rate for any
Interest Period for any LIBOR Advances will not adequately reflect the cost to
such Lender of making, funding or maintaining LIBOR Advances for such Interest
Period, Administrative Agent shall promptly so notify the Borrower, whereupon
(i) each such LIBOR Advance will automatically, on the last day of the then
existing Interest Period therefor, convert into a Base Advance and (ii) the
obligation of such Lender to make, or to convert Advances into, LIBOR Advances
shall be

                                      35
<PAGE>

suspended until such Lender notifies Administrative Agent that such Lender has
determined that the circumstances causing such suspension no longer exist and
Administrative Agent notifies the Borrower of such fact.

     (f) Failure on the part of any Lender to demand compensation for any
increased costs, increased capital or reduction in amounts received or
receivable or reduction in return on capital pursuant to this Section 2.14 with
respect to any period shall not constitute a waiver of any Lender's right to
demand compensation with respect to such period or any other period, subject,
however, to the limitations set forth in this Section 2.14.

     (g) The obligations of the Borrower under this Section 2.14 shall survive
any termination of this Agreement, provided that, in no event shall the Borrower
                                   -------------
be required to make a payment under this Section 2.14 with respect to any event
of which the Lender making such claim had knowledge more than 12 months prior to
demand for such payment.

     (h) Determinations by Lenders for purposes of this Section 2.14 shall be
presumptively correct.  Any certificate delivered to the Borrower by a Lender
pursuant to this Section 2.14 shall include in reasonable detail the basis for
such Lender's demand for additional compensation and a certification that the
claim for compensation is consistent with such Lender's treatment of similar
customers having similar provisions generally in their agreements with such
Lender.

     (i) Notwithstanding any other provision of this Agreement, no Lender not
organized under the Laws of the United States or any State (or which has a Bank
Affiliate not organized under the Laws of the United States or any State) shall
be entitled to compensation pursuant to this Section 2.14 with respect to any
amount which would otherwise be due under this Section 2.14 but which is the
result of an act of a Tribunal of the country in which such Lender or Bank
Affiliate is organized.

     2.15.  Use of Proceeds.  The Borrower agrees to use the proceeds of the
Loans exclusively to:

          (a)  Prior to such time as the Senior Unsecured Debt Rating is BBB- or
          Baa3 or better and the Conditional Early Release Unlimited Guaranty
          has been released in accordance with the terms of Section 10.14
          hereof:

               In accordance with certain of the Existing Financing
          Documentation, finance or refinance all or any part of the cost of,
          the construction, installation, acquisition or improvement by the
          Borrower or any Restricted Subsidiary (as defined in the Existing
          Financing Documentation) of the Borrower of any new
          "Telecommunications Assets" (as defined below) constructed, installed,
          acquired or improved after March 31, 1997, provided that (i) the
                                                     -------------

     (c) Notwithstanding anything herein or in any other Loan Paper to the
contrary,

               (i)    the Borrower is not obligated to request participation
          from, or allocate to, any existing Lender any portion of the proposed
          increase.  Each existing Lender agrees and acknowledges that new
          creditors may be allocated all or any portion of the proposed increase
          upon the determination of the Borrower and the Administrative Agent,

               (ii)   the addition of any new facility hereunder will require an

          agree to execute any and all amendments and/or agreements reasonably
          requested by the Administrative Agent and the Borrower to effectuate
          the intent of this Section 2.16.

Section 2.14(a) or (b) hereof or (ii) any Lender delivers a notice described in
Section 2.14(c) or (e) hereof then such Lender shall use reasonable efforts
(which shall not require such Lender to suffer any disadvantage or burden
reasonably deemed by it (in good faith) to be significant, including without
limitation, to incur an unreimbursed loss or unreimbursed cost or expense or
otherwise take any action inconsistent with its internal policies or legal or
regulatory restrictions), promptly thereafter, (x) to file any certificate or
document reasonably requested in writing by the Borrower or (y) to assign its
Rights and delegate and transfer its obligations hereunder to another of its
offices, branches or Bank Affiliates, if such filing or assignment would reduce
its claims for compensation under Section 2.14(a) or (b) hereof or enable it to
withdraw its notice pursuant to Section 2.14(c) or (e) hereof, as the case may
be, in the future.  The Borrower hereby agrees to pay all reasonable costs and
expenses incurred by any Lender in connection with any such filing or
assignment, delegation and transfer.

     (b) Replacement of a Lender Upon Request for Compensation.  If any Lender
has requested compensation or reimbursement in accordance with the terms of
Section 2.14 hereof and (i) such request is not the result of any uniform
changes in the statutes or regulations for capital adequacy, and (ii) the
Borrower and such Lender are unable to reach a written agreement regarding such
request within 30 days following written notice by such Lender to the Borrower
and the Administrative Agent of such request, then after the expiration of 30
days following the delivery of the notice under Section 2.14 hereof, the
Borrower may replace such Lender in whole with another Lender acceptable to the
Arranging Agents pursuant to an Assignment and Acceptance and in accordance with
Section 10.04 hereof, provided that, such Lender is replaced at par value of all
                      -------------
Obligations owing such Lender plus all accrued interest and fees, provided
further, that Borrower pays the assignment and acceptance fee set forth in
Section 10.04(a) hereof for such replacement.  Until such time as any Lender is
replaced by the Borrower, the Borrower shall reimburse or compensate such Lender
in accordance with the terms of Section 2.14 hereof.

     2.18.  Rights of Borrower in Respect of Failure of any Lender to Fund.
If any Lender shall breach its agreement to make any Advance available in
accordance with the terms of this Agreement (and each other Lender shall have
made its portion of the Advance available to the Borrower) then, such Lender
shall, promptly upon the written request of the Borrower to such Lender and the
Administrative Agent, assign all of its Rights and duties hereunder and under
the other Loan Papers pursuant to an Assignment and Acceptance in accordance
with the terms of Section 10.04 hereof to another financial institution or
lender designated by the Borrower and acceptable to the Arranging Agents in
accordance with the terms of Section 10.04 hereof, provided that,
                                                   -------------
notwithstanding the foregoing, in no event shall any Lender be required to take
any such action if (a) such Lender is owed any payments by the Borrower pursuant
to this Agreement or the other Loan Papers, (b) there exists any Default or
Event of Default.

applicable provisions of ERISA, the Code, and any other applicable Federal or
state law, rule or regulation, except such non-compliance which is not, and

respect to each Plan of the Borrower and each member of its Controlled Group
(other than a Multiemployer Plan), all reports required under ERISA or any other
Applicable Law to be filed with any governmental authority, the failure of which
to file would reasonably result in liability of the Borrower, or any member of
its Controlled Group in excess of $10,000,000, have been duly filed.  All such
reports are true and correct in all material respects as of the date given. On
the Closing Date other than as disclosed to the Administrative Agent in writing,

under Section 4041(c)(3)(C), 4068(f), 4063(a) or 4043(b) of ERISA with respect
to any Plan or trust of the Borrower, or any member of its Controlled Group
within 60 months prior to the Closing Date or thereafter, except as disclosed to
the Administrative Agent in writing.  The value of the assets of each Plan
(other than a Multiemployer Plan) of the Borrower and each member of its
Controlled Group equaled or exceeded the present value of the benefit
liabilities, determined on an on-going Plan basis, as defined in Title IV of
ERISA, of each such Plan as of the most recent valuation date using Plan
actuarial assumptions at such date.  There are no pending or, to the actual
knowledge of an Authorized Officer, threatened claims, lawsuits or actions
(other than routine claims for benefits in the ordinary course) asserted or
instituted against (i) the assets of any Plan or trust or against any fiduciary

None of the Borrower, or any member of its Controlled Group has engaged in any
non-exempt prohibited transactions, within the meaning of Section 406 of ERISA
or Section 4975 of the Code, in connection with any Plan, except such
transactions which are not, or would not in the aggregate reasonably be expected
to cause, a Material Adverse Change. None of the Borrower or any member of its
Controlled Group has incurred or reasonably expects to incur any liability under
Title IV of ERISA (other than premiums due under Section 4007 of ERISA to the
PBGC) in excess of $10,000,000. None of the Borrower any member of its
Controlled Group, or, to the actual knowledge of any Authorized Officer, any
organization to which the Borrower or any member of its Controlled Group is a
successor or parent corporation within the meaning of ERISA Section 4069(b), has
engaged in a transaction within the meaning of ERISA Section 4069. None of the
Borrower or any member of its Controlled Group maintains or has established any
welfare benefit plan within the meaning of Section 3(1) of ERISA which provides
for continuing benefits or coverage for any participant or any beneficiary of
any participant after such participant's termination of employment except as may
be required by the Consolidated Omnibus Budget Reconciliation Act of 1985, as
amended ("COBRA") and the regulations thereunder, and at the expense of the
participant or the beneficiary of the participant, or retiree medical
liabilities, except any such plan that would not reasonably be expected to
result in material liability to the Borrower or any Qwest Material Subsidiary.

plan within the meaning of Section 3(1) of ERISA has complied in all material
respects with any applicable notice and continuation requirements of COBRA and

business of extending credit for the purpose of purchasing or carrying any
margin stock within the meaning of Regulations T, U and X of the Board of
Governors of the Federal Reserve System, and no part of the proceeds of the
Advances will be used to purchase or carry any margin stock (as defined by
Regulation U) or to extend credit to others for the purpose of purchasing or
carrying any margin stock.  Not more than 25% of the assets of any of the
Borrower or any of its Subsidiaries are margin stock (as defined by Regulation
U).  None of the Borrower and its Subsidiaries, nor any agent acting on their
behalf, has taken any action which might cause this Agreement or any Loan Papers
to violate any regulation of the Board of Governors of the Federal Reserve
System or to violate the Exchange Act, in each case as in effect now or as the
same may hereafter be in effect from time to time.

     (n) Event of Default.  The Borrower and the Qwest Material Subsidiaries are
         ----------------
in compliance with all of the provisions of their articles of incorporation.
The Borrower and the Qwest Material Subsidiaries are in material compliance with
all of the provisions of their by-laws.  No event has occurred or failed to

         ------------------------------
its Subsidiaries, required to register under the provisions of the Investment
Company Act of 1940, as amended (the "ICA").  Neither the entering into or
performance by the Borrower of this Agreement nor the issuance of the Notes, nor
the execution, delivery and performance of the obligations by the Borrower and
its Restricted Subsidiaries under the Loan Papers, violates any provision of the
ICA

                                      47
<PAGE>

or requires any consent, approval, or authorization of, or registration with,

of authority pursuant to any provisions of the ICA.

     (p) Environmental.  On the Closing Date, no Authorized Officer has any
         -------------
actual knowledge that any Hazardous Substance has been installed on any real
property now owned by the Borrower or any of its Restricted Subsidiaries, except
(i) for Hazardous Substances the presence of which is not in violation of
Environmental Law in an amount which is not or would not reasonably be expected
to cause, liability to the Borrower or any Restricted Subsidiary in the
aggregate in excess of $5,000,000 or (ii) as set forth on Schedule 4.01(p)
                                                          ----------------

Subsidiary has any actual knowledge that any Hazardous Substance has been

knowledge of an Authorized Officer, the Borrower and the Restricted Subsidiaries
are not in material violation of or subject to any existing, pending or material
threatened formal investigation or formal inquiry by any governmental authority,
or subject to any material remedial obligations under any applicable
Environmental Laws.  On each date after the Closing Date on which this
representation is deemed to be made, to the actual knowledge of an Authorized
Officer, the Borrower and the Restricted Subsidiaries are not in violation of or
subject to any existing, pending  or threatened formal investigation or inquiry
by any governmental authority or to any remedial obligations under any
applicable Environmental Laws which in each case is, or would reasonably be
expected to cause, a Material Adverse Change.  To the actual knowledge of an
Authorized Officer, the Borrower and the Restricted Subsidiaries are not
required to obtain any material permits, Licenses or similar authorizations to
construct, occupy, operate or use any buildings, improvements, fixtures, and
equipment forming a part of any real property of the Borrower or any Restricted
Subsidiary by reason of any applicable Environmental Laws, except those that
have been obtained, or which the failure to obtain has not, and would not
reasonably be expected to cause, a Material Adverse Change.  As of the  Closing
Date, except as set forth in Schedule 4.01(p) hereto, no Authorized Officer has
                             ----------------
actual knowledge that any Hazardous Substances or solid wastes have been
disposed of on the real property of the Borrower or any of its Restricted
Subsidiaries in violation of any applicable Environmental Law, except such
violations which are not, and would not reasonably be expected to cause,
liability to the Borrower and/or the Restricted Subsidiaries in the aggregate in
excess of $5,000,000.  As of the Closing Date, except as set forth in Schedule
                                                                      --------
4.01(p) hereto, no Authorized Officer has actual knowledge that any Hazardous
-------
Substances or solid wastes have been released on or to the real property of the
Borrower or any of its Restricted Subsidiaries in violation of any applicable
Environmental Law, except such violations which are not, and would not
reasonably be expected to cause, liability to the Borrower and/or the Restricted
Subsidiaries in the aggregate in excess of $10,000,000.  On each date after the
Closing Date on which this representation is deemed to be made, no Authorized
Officer of the Borrower and the Restricted Subsidiaries has actual knowledge
that any Hazardous Substances or solid wastes have been disposed of or otherwise
released on or to the real property of the Borrower or any of the Restricted
Subsidiaries, in violation of the applicable Environmental Laws, except any such
disposal or release which is not, and would not reasonably be expected to cause,
a Material Adverse Change.

     (q) Subsidiaries.  As of the Closing Date,, the Borrower has no
         ------------
Subsidiaries other than those Subsidiaries specifically disclosed in part (a) of
Schedule 4.01(q) hereto and has no equity
----------------

                                      48
<PAGE>

investments in any other Person other than those specifically disclosed in part
(b) of Schedule 4.01(q) hereto.
       ----------------

     (r) Broker's Fees.  No broker's, finder's or other similar fee or
         -------------
commission will be payable by the Borrower (other than to the Agents and the
Lenders hereunder) with respect to the making of the Commitment or the Advances
hereunder.

     (s) Intellectual Property.  To the actual knowledge of the Authorized
         ---------------------
Officers as of the Closing Date, the Borrower and its Restricted Subsidiaries
have obtained all licenses of material patents, trademarks, service-marks, trade
names, copyrights, and other rights from third parties that are necessary for
the operation of their business as presently conducted.  On each date after the
Closing Date on which this representation is deemed to be made, the Borrower and
the Restricted Subsidiaries have obtained all Licenses of patents, trademarks,
service-marks, trade names, copyrights and other similar rights that are
necessary for the operation of their business as presently conducted, except
those, the failure of which to obtain has not caused, and would not reasonably
be expected to cause, a Material Adverse Change.  Nothing has come to the
attention of the Borrower or any of the Restricted Subsidiaries to the effect
that (i) any process, method, part or other material presently contemplated to
be employed by the Borrower or any Qwest Material Subsidiary may infringe any
patent, trademark, service-mark, trade name, copyright, or other right owned by
any other Person except to the extent Borrower or any of the Restricted
Subsidiaries has obtained a License therefor, or (ii) there is pending or
overtly threatened any claim or Litigation against or affecting the Borrower or
any Qwest Material Subsidiary contesting its right to sell or use any such
process, method, part or other material, except in the case of clause (i) and
(ii) above, any such event or circumstance which has not caused, and would not
reasonably be expected to cause, a Material Adverse Change.

     (t) Accuracy of Borrower Information.  On the Closing Date, neither this
         --------------------------------
Agreement nor any other document, certificate or statement (in each case, taken
as a whole but excluding the Offering Memorandum) which has been furnished to
any Lender by or on behalf of the Borrower or any of its Subsidiaries in
connection herewith contained any materially untrue statement of a material fact
or omitted to state a material fact necessary in order to make the statement
contained herein and therein not materially misleading at the time it was
furnished in light of the circumstances under which they were made, provided
                                                                    --------
that notwithstanding anything to the contrary in this Agreement or in the Loan
----
Papers, the Borrower makes no representation, warranty or guaranty as to any
projections furnished to the Lenders except that they were prepared in good
faith by the Borrower on the basis of assumptions which the Borrower believed
were reasonable as of the date of such projections.  On each date after the
Closing Date on which this representation is deemed to be made, the Borrower
represents that none of the regular or periodic reports, or any registration
statement or prospectus filed by the Borrower or any Restricted Subsidiary with
the Securities and Exchange Commission (or any successor agency) contains any
materially untrue statement of a material fact or omits to state a material fact
necessary in order to make the statement contained therein not materially
misleading at the time of such filing in light of the circumstances under which
they were made.  The historical financial statements of the Borrower and
Guarantor contained in the Offering Memorandum present fairly in all material
respects and in accordance with GAAP (subject to year end adjustments and the
absence of footnotes as to the Borrower's unaudited financial statements
contained therein) the financial position of the Borrower and the Guarantor,
respectively, and their respective consolidated Subsidiaries as of the date of
such financial statements.

         --------------------
the Borrower reasonably believes that the Year 2000 Problem will not result in,
a Material Adverse Change.

     (v) Existing Financing.  The Loans and the Conditional Early Release
         ------------------
Unlimited Guaranty of the Loans and all Obligations are senior to or pari passu
with all Existing Financing.  Nothing in this Agreement and the other Loan
Papers violates any provision of the Existing Financing Documentation, and no
consent is required in connection with any of the Existing Financing
Documentation in order to execute, deliver and perform under this Agreement and
the other Loan Papers.  To the actual knowledge of the Authorized Officers,
there exists no "Default" or "Event of Default" as defined in, and under any of
the Existing Financing Documentation, or any other event or circumstance which
causes a Repayment Event with respect to any of the Existing Financing.  All
notices required by any Existing Financing Documentation regarding the
execution, delivery or performance by the Borrower or any Restricted Subsidiary
of the Loan Papers have been given in accordance with the terms of the Existing
Financing Documentation.

     (w) Fibers and Fiber Capacity. As of the Closing Date, the Borrower and its
         -------------------------
Restricted Subsidiaries own or have the right to use through the Maturity Date
not less than 24 optical fibers on a weighted average route mile basis on the
Backbone (which such fibers are not subject to any transfer, disposition or IRU
Agreement granting an IRU to any Person other than the Borrower or any
Restricted Subsidiary), and such fiber capacity is sufficient, on a weighted
average route mile basis, to meet the business plan of the Borrower.

     (x) Sinking Funds and Defeasance.  As of the Closing Date, no documentation
         ----------------------------
relating to any Debt for Borrowed Money of the Borrower or any Restricted
Subsidiary has any provision granting any creditor a sinking fund or a right to
require a defeasance of the obligations owing to it.

and warranties made under this Agreement and the other Loan Papers shall be
deemed to be made at and as of the Closing Date and at and as of the date of
each Advance (excluding each Refinancing Advance), and each shall be true and

representations and warranties shall survive, and not be waived by, the
execution hereof by any Lender, any investigation or inquiry by any Lender, or
by the making of any Advance under this Agreement.

     5.07.  Visits and Inspections.  The Borrower shall, and shall cause each
Restricted Subsidiary to, promptly, permit representatives of the Administrative
Agent and the Arranging Agents, or any Lender accompanied by the Administrative
Agent from time to time, upon prior notice reasonable under the circumstances,
to (a) visit and inspect the Properties of the Borrower and each Restricted
Subsidiary during normal business hours (unless there exists an Event of Default
in which case during such hours as is reasonable under the circumstances), (b)
inspect and make extracts from and copies of the Borrower's and each Restricted
Subsidiary's books and records, in each case as reasonable under the
circumstances, (c) discuss with the Borrower's and each Restricted Subsidiary's
officers (and during an Event of Default, with the Auditors together with an
Authorized Officer of the Borrower), its business, assets, liabilities,
financial positions, results of operations and business prospects, and (d) make
reasonable informational requests of the Auditors from time to time, with
respect to which the Borrower shall be obligated to procure such information
from the Auditors.

     5.08.  Use of Proceeds.  The Borrower agrees that the proceeds of the
Loans shall be used in accordance with the terms of Section 2.15 hereof.

     5.09.  Indemnity.  The Borrower agrees to indemnify and hold harmless
the Administrative Agent, the Lead Arranger, the Arranging Agents, the Co-
Arrangers, the Co-Syndication Agents, each Lender and their respective
affiliates, officers, directors, employees, agents and advisors (each, an
"Indemnified Party") from and against any and all claims, damages, losses,
liabilities and expenses (including, without limitation, the reasonable fees and
expenses of counsel and the allocated cost of internal counsel) which may be
incurred by or asserted or awarded against any Indemnified Party, in each case
arising out of or in connection with or by reason of, or in connection with the
preparation for a defense of, any investigation, litigation or proceeding
arising out of, related to or in connection with the Loans, including without
limitation, any transaction in which the proceeds of any borrowing are or are to
be applied, whether or not an Indemnified Party is a party thereto, whether or
not the transactions contemplated herein are consummated, and whether or not
such claim, damage, loss, liability or expense results from the negligence of
such Indemnified Party unless and only to the extent that as to any Indemnified
Party, it shall be determined in a final, non-appealable judgment by a court of
competent jurisdiction that such losses, claims, damages, liabilities, or
expenses resulted from such Indemnified Party's gross negligence or willful
misconduct.  Borrower will not settle or consent to judgment with respect to any
investigation, litigation, or proceeding without the prior written consent of
the Administrative Agent and any affected Indemnified Party, unless such
settlement or consent includes an unconditional release of each such Indemnified
Party or unless each Indemnified Party is entitled to be indemnified under this
Section 5.09 (which entitlement the Borrower will confirm to such Indemnified
Party in writing, if requested).  The Borrower shall periodically, upon request,
reimburse each Indemnified Party for its reasonable legal and other actual
expenses (including the costs of any investigation and preparation) incurred in
connection with any indemnified matter.  The Borrower agrees that no Indemnified
Party shall have any liability for any indirect or consequential damages in
connection with its activities related to the Loans.  The reimbursement,
indemnity and contribution obligations under this Section shall be in addition
to any liability which the Borrower may otherwise have, shall extend upon the
same terms and conditions to each Indemnified Party, and shall be binding upon
and inure to the benefit of any successors, assigns, heirs and personal
representatives of the Borrower, the Administrative Agent, the Lenders and all
other Indemnified Party.  This Section shall survive any termination of this
Agreement and repayment of the Obligations.

     5.10.  Environmental Law Compliance.  The use which the Borrower or any
of its Restricted Subsidiaries intends to make of any real Property owned by it
will not result in the disposal or other release of any Hazardous Substance or
solid waste on or to such real Property in violation of any Environmental Law,
except any such violation which is not, and would not reasonably be expected to
cause, a Material Adverse Change.  As used herein, the term "release" as used in
this Section shall have the meanings specified in CERCLA (as defined in the
definition of applicable Environmental Laws), and the terms "solid waste" and
"disposal" shall have the meaning specified in RCRA (as defined in the
definition of applicable Environmental Laws); provided, however, that if CERCLA
or RCRA is amended so as to broaden or narrow the meaning of any term defined
thereby, such broader or narrower meaning shall apply subsequent to the
effective date of such amendment; and provided further, to the extent that any
other law applicable to the Borrower, any of its Restricted Subsidiaries or any
of their properties and assets establishes a meaning for "hazardous substance,"
"release," "solid waste," or "disposal" which is broader than that specified in
either CERCLA or RCRA, such broader meaning shall apply.  The Borrower and each
Restricted Subsidiary agrees to indemnify and hold the Administrative Agent and
each Lender harmless from and against, and to reimburse them with respect to,
any and all claims, damages, losses, liabilities and expenses (including
reasonable attorneys' fees and courts costs) asserted or awarded against or
incurred by any of them by reason of or arising out of transactions contemplated
by this Agreement and (a) the failure of the Borrower or any of its Restricted
Subsidiaries to perform any obligation hereunder regarding asbestos or
applicable Environmental Laws, (b) any violation by the Borrower or Restricted
Subsidiary on or before the Release Date of any applicable Environmental Law in
effect on or before the Release Date, and (c) any act, omission, event or
circumstance existing or occurring on or prior to the Release Date, involving
the presence on such real Property or release from such real Property of
Hazardous Substances or solid wastes disposed of or otherwise released on or
prior to the Release Date, resulting from or in connection with the ownership by
the Borrower or any Restricted Subsidiary of the real Property, regardless of
whether the act, omission, event or circumstance constituted a violation of any
applicable Environmental Law at the time of its existence or occurrence, or
whether the act, omission, event or circumstance is caused by or relates to the
negligence of any indemnified Person; provided, that the Borrower shall not be
under any obligation to indemnify the Administrative Agent or any Lender to the
extent that any such liability arises as the result of the gross negligence or
willful misconduct of such Person, as finally judicially determined by a court
of competent jurisdiction.  The provisions of this Section shall survive the
Release Date and shall continue thereafter in full force and effect.

     5.11.  Restricted Subsidiary Designation.    The Borrower agrees that each
Restricted Subsidiary on the Existing Bank Facility Closing Date will remain a
Restricted Subsidiary until the Obligations have been repaid in full and the
Commitment has been terminated, unless any such Restricted Subsidiary that is
not a Qwest Material Subsidiary has been Disposed of in accordance with the
terms of Section 7.05(a)(ii)(A) hereof.  The Borrower agrees that, without the
consent of the Majority Lenders, the  Designated U S WEST Restricted Subsidiary
will remain a Restricted Subsidiary until the Obligations have been repaid in
full and the Commitment has been terminated.

     5.12.  Fiber Capacity.   The Borrower shall, and shall cause its Restricted
Subsidiaries to, at all times maintain ownership of or the right to use through
the Maturity Date (or until all Obligations are paid in full) not less than 24
optical fibers on a weighted average route mile basis on the Backbone, which
such fibers may not be transferred, disposed of or made subject to an IRU
Agreement granting an IRU to any Person other than the Borrower or any
Restricted Subsidiary if such transfer, disposal or IRU Agreement would result
in the Borrower and its Restricted

                                      53
<PAGE>

Subsidiaries owning or having the right to use less than 24 optical fibers on a
weighted average route mile basis on the Backbone through the Maturity Date (or
until all Obligations are paid in full).

     5.13.  UCC Filings.  The Borrower shall, and shall cause its Restricted
Subsidiaries to, agree to file UCC-3 releases for all UCC filings recorded
against the Borrower and its Restricted Subsidiaries, which such UCC filings
evidence Debt that has been repaid in full and extinguished and do not evidence
Liens permitted under Section 7.03 hereof.

     5.14.  Sinking Funds and Defeasance.  To the extent that the Borrower or
any Restricted Subsidiary agrees in connection with the incurrence of any Debt
for Borrowed Money to a sinking fund or defeasance, the Borrower shall, and
shall cause each of its Restricted Subsidiaries to, grant to the Administrative
Agent and the Lenders proportionately similar rights to a sinking fund or
defeasance with respect to the Obligations.

     5.15.  Reimbursement of Costs and Expenses.  Within 30 days after the
Closing Date,  the Borrower shall reimburse the Administrative Agent for the
reasonable costs, fees and expenses (including the reasonable fees and expenses
of Special Counsel) incurred by the Administrative Agent in connection with the
negotiation, preparation and execution of this Agreement, the other Loan Papers
and the making of the initial Loans.

exceeding $10,000,000;

     (k) Any of the Borrower or any of its Original Restricted Subsidiaries
shall be required under any Environmental Law: (i) to implement any remedial,
neutralization, or stabilization process or program, other than any such process
or program the cost of which has not had, and would not reasonably be expected

leased or owned), or the operations conducted thereon by any of the Borrower or
any of its Original Restricted Subsidiaries, or any current or prior owner or

and would not reasonably be expected to have,  a Material Adverse Effect; or
(ii) the Borrower or such Original Restricted Subsidiary shall not obtain or

<PAGE>

     (r) (i) Any U S WEST Restricted Subsidiary shall fail to comply with any of
the provisions of Sections 5.07, 5.11, 6.01, 6.02, 6.04(d), or 6.07 hereof, and
such failure shall continue after the grace period set forth in Section 8.01(d)
hereof applicable to such Section; or (ii)  any U S WEST Restricted Subsidiary

Adverse Effect has occurred as a result of any of the events set forth in
Sections 8.08(a)(i)-(iv) hereof, as modified by the last clause thereof.

     8.02.  Remedies upon Default.  If an Event of Default described in
Section 8.01(f) shall occur, the aggregate unpaid principal balance of and
accrued interest on all Advances and all other Obligations shall, to the extent
permitted by applicable Law, thereupon become due and payable concurrently
therewith, and the Commitment shall be concurrently automatically reduced to
zero and terminated, all without any action by Administrative Agent or any
Lender, and without diligence, presentment, demand, protest, notice of protest
or intent to accelerate, or notice of any other kind, all of which are hereby
expressly waived.  Subject to the foregoing sentence, if any Event of Default
shall occur and be continuing, Administrative Agent may at its election, and
shall at the direction of Majority Lenders, do any one or more of the following:

     (a) Declare the entire unpaid balance of all Obligations immediately due
and payable, whereupon it shall be due and payable without diligence,
presentment, demand, protest, notice of protest or intent to accelerate, or
notice of any other kind (except notices specifically provided for under Section
8.01 hereof), all of which are hereby expressly waived (except to the extent
waiver of the foregoing is not permitted by applicable Law);

     (b)  Terminate the Commitment;

     (c) Reduce any claim of Administrative Agent and Lenders to judgment; or

     (d) Exercise any Rights afforded under any Loan Papers, by Law, including
but not limited to the UCC, at equity, or otherwise.

     8.03.  Cumulative Rights.  All Rights available to Administrative Agent
and Lenders under the Loan Papers shall be cumulative of and in addition to all
other Rights granted thereto at Law or in equity, whether or not amounts owing
thereunder shall be due and payable, and whether or not

                                      76
<PAGE>

the Administrative Agent or any Lender shall have instituted any suit for
collection or other action in connection with the Loan Papers.

     8.04.  Waivers.  The acceptance by Administrative Agent or any Lender at
any time and from time to time of partial payment of any amount owing under any
Loan Papers shall not be deemed to be a waiver of any Default or Event of
Default then existing.  No waiver by Administrative Agent or any Lender of any
Default or Event of Default shall be deemed to be a waiver of any Default or
Event of Default other than such Default or Event of Default.  No delay or
omission by Administrative Agent or any Lender in exercising any Right under the
Loan Papers shall impair such Right or be construed as a waiver thereof or an
acquiescence therein, nor shall any single or partial exercise of any such Right
preclude other or further exercise thereof, or the exercise of any other Right
under the Loan Papers or otherwise.

     8.05.  Performance by Administrative Agent or any Lender.  Should any
covenant of any Obligor or Restricted Subsidiary fail to be performed in
accordance with the terms of the Loan Papers, Administrative Agent may, at its
option, perform or attempt to perform such covenant on behalf of such Obligor or
Restricted Subsidiary.  Notwithstanding the foregoing, it is expressly
understood that the Administrative Agent does not assume, and shall not ever
have, except by express written consent of the Administrative Agent, any
liability or responsibility for the performance of any duties or covenants of
any Obligor or Restricted Subsidiary.

     8.06.  Expenditures.  The Borrower shall reimburse Administrative Agent
for any reasonable sums spent by it in connection with the exercise of any Right
under Section 8.05 hereof.  Such sums shall bear interest at the lesser of (a)
the Base Rate (whether or not in effect), plus 2.00% per annum and (b) the
Highest Lawful Rate, from 15 days after the date the Administrative Agent makes
demand to the Borrower for reimbursement of such amount until the date of
repayment by the Borrower.

     8.07.  Control.  None of the covenants or other provisions contained in
this Agreement shall, or shall be deemed to, give Administrative Agent or any
Lender any Rights to exercise control over the affairs and/or management of any
of the Borrower or any of its Subsidiaries being limited to the Rights to
exercise the remedies provided in this Article; provided, however, that if
                                                --------  -------
Administrative Agent or any Lender becomes the owner of any partnership, stock
or other equity interest in any Person, whether through foreclosure or
otherwise, it shall be entitled to exercise such legal Rights as it may have by
being an owner of such stock or other equity interest in such Person.

     8.08.  Compliance Concerning U S WEST Companies and Their Assets.

          (a)  Notwithstanding anything in this Agreement or in any of the Loan
     Papers to the contrary (but subject to subsections (b) and (c) below),
     after the Acquisition Date, no breach of this Agreement, Default or Event
     of Default shall be deemed to have occurred and no condition precedent set
     forth in Article III hereof shall fail to be satisfied, as a result of:

               (i) the inaccuracy of any representation or warranty contained in
          Article IV hereof,

                                      77
<PAGE>

               (ii) any failure to comply with the provisions of any affirmative
          covenant contained in Article V hereof (other than any provisions
          contained in Sections 5.07 and 5.11 hereof),

               (iii)  any failure to comply with any information covenant
          contained in Article VI hereof (other than any provisions contained in
          Sections 6.01, 6.02 , 6.04(d) and 6.07 hereof),

               (iv) any failure to comply with any negative covenant contained
          in Article VII hereof (other than Sections 7.01, 7.02, 7.04, 7.07 and
          7.16 hereof) and

               (v) the occurrence of any event that would otherwise constitute
          any Default or Event of Default contained in Article VIII hereof
          (other than under Sections 8.01(e), (o), (q) and (r) hereof),

     in each case set forth in (i) through (v) above, only to the extent that
     any such inaccuracy of any such representation or warranty, or failure to
     comply, failure to satisfy a condition precedent, Default or Event of
     Default is wholly or in part caused by, or attributable to, any U S WEST
     Company or the assets or liabilities of any U S WEST Company (a "U S WEST
     Event");

          (b)  Section 8.08(a) above shall only be effective when:

               (i) at least one of the U S WEST Restricted Subsidiaries has in
          effect, and is bound by, a bank credit facility in excess of
          $100,000,000,

               (ii) the U S WEST Event has not caused the occurrence of a
          Material Adverse Effect, and

               (iii)  the Original Borrower and the Original Subsidiaries are
          otherwise in compliance with all such provisions exempting U S WEST
          Companies; and

          (c)  Notwithstanding any provision of Section 8.08(a) above:

               (i) each U S WEST Restricted Subsidiary shall be subject to, and
          bound by, the terms and provisions contained in Sections 5.07, 5.11,
          6.01, 6.02., 6.04(d), 6.07, 7.01, 7.02, 7.04, 7.07 and 7.16 hereof,

               (ii) any Default or Event of Default under Sections 8.01(a), (e),
          (o), (q) and (r) that is wholly or in part caused by, or attributable
          to, any of the U S WEST Restricted Subsidiaries or the assets or
          liabilities of any of the U S WEST Restricted Subsidiaries, shall be a
          Default or Event of Default hereunder, as applicable, and

               (iii)  although, in accordance with the terms of this Section
          8.08, the U S WEST Restricted Subsidiaries are not subject to the
          limitations of certain of the negative covenants of this Agreement,
          each U S WEST Restricted Subsidiary shall be included in any
          exceptions to such limitations to the extent that the U S WEST
          Restricted Subsidiaries would, but for this Section 8.08, fall within
          such exceptions.

                                      78
<PAGE>

          For the avoidance of doubt, (1) the U S WEST Restricted Subsidiaries
          that meet the definition of "Wholly Owned Restricted Subsidiaries",
          shall be considered and included in the definition of "Wholly Owned
          Restricted Subsidiaries" for purposes of (A) the parenthetical in
          Section 7.08 hereof, (B) Sections 7.10 (a)(i), (b)(ii) and 7.11 (a)
          hereof, and (C) the second reference thereto in Section 7.18 (b)
          hereof, and (2) the U S WEST Restricted Subsidiaries shall be
          considered "Restricted Subsidiaries" for purposes of the second and
          fourth references thereto in Section 7.17 hereof.

                     ARTICLE IX  THE ADMINISTRATIVE AGENT

     9.01.  Authorization and Action.  Each Lender hereby appoints and
authorizes Administrative Agent to take such action as Administrative Agent
deems necessary on its behalf and to exercise such powers under this Agreement
and the other Loan Papers as are delegated to the Administrative Agent by the
terms of the Loan Papers, together with such powers as are reasonably incidental
thereto.  As to any matters not expressly provided for by this Agreement and the
other Loan Papers (including without limitation enforcement or collection of the
Notes), Administrative Agent shall not be required to exercise any discretion or
take any action, but shall be required to act or to refrain from acting (and
shall be fully protected in so acting or refraining from acting) upon the
instructions of Majority Lenders (or all Lenders, if required under Section
10.01 hereof), and such instructions shall be binding upon all Lenders;
provided, however, that Administrative Agent shall not be required to take any
--------  -------
action which exposes Administrative Agent to personal liability or which is
contrary to any Loan Papers or applicable Law.  Administrative Agent agrees to
give to each Lender (a) notice of each notice given to it by the Borrower
pursuant to the terms of this Agreement, (b) copies of all information delivered
to the Administrative Agent in accordance with the terms of Sections 6.01, 6.02
and 6.03 hereof and (c) to promptly distribute to each applicable Lender in like
funds all amounts delivered to Administrative Agent by the Borrower for the
individual account of any Lender pro rata in accordance with the Specified
Percentage, as set forth in this Agreement.  Functions of the Administrative
Agent are administerial in nature and in no event shall the Administrative Agent
have a fiduciary or trustee relationship in respect of any Lender by reason of
this Agreement or any other Loan Paper.

     9.02.  Administrative Agent's Reliance, Etc.  Neither Administrative
Agent, nor any of its directors, officers, agents, employees, or representatives
shall be liable for any action taken or omitted to be taken by it or them under
or in connection with this Agreement or any other Loan Paper, except for its or
their own gross negligence or willful misconduct.  Without limitation of the
generality of the foregoing, Administrative Agent (a) may treat the payee of any
Note as the holder thereof until Administrative Agent receives written notice of
the assignment or transfer thereof signed by such payee and in form satisfactory
to Administrative Agent; (b) may consult with legal counsel (including counsel
for the Borrower or any of the Restricted Subsidiaries), independent public
accountants, and other experts reasonably selected by it, and shall not be
liable for any action taken or omitted to be taken in good faith by it in
accordance with the advice of such counsel, accountants, or experts; (c) makes
no warranty or representation to any Lender and shall not be responsible to any
Lender for any statements, warranties, or representations made in or in
connection with this Agreement or any other Loan Papers; (d) shall not have any
duty to ascertain or to inquire as to the performance or observance of any of
the terms, covenants, or conditions of this Agreement or any other Loan Papers
on the part of the Borrower or the Restricted Subsidiaries or to inspect the
Property (including the books and records) of the Borrower or its Subsidiaries;
(e) shall not be responsible to any Lender for

                                      79
<PAGE>

the due execution, legality, validity, enforceability, genuineness, sufficiency,
or value of this Agreement, any other Loan Papers, or any other instrument or
document furnished pursuant hereto; and (f) shall incur no liability under or in
respect of this Agreement or any other Loan Papers by acting upon any notice,
consent, certificate, or other instrument or writing believed by it to be
genuine and signed or sent by the proper party or parties.

     9.03.  Bank of America, N.A. and Affiliates.  With respect to its
Commitment, its Advances, and any Loan Papers, Bank of America, N.A. has the
same Rights under this Agreement as any other Lender and may exercise the same
as though it were not Administrative Agent.  Bank of America, N.A. and its
Affiliates may accept deposits from, lend money to, act as trustee under
indentures of, and generally engage in any kind of business with, any Obligor,
any Restricted Subsidiary, any Affiliate thereof, and any Person who may do
business therewith, all as if Bank of America, N.A. were not Administrative
Agent and without any duty to account therefor to any Lender, including, without
limitation, the TROL Transaction.

     9.04.  Lender Credit Decision.  Each Lender acknowledges that it has,
independently and without reliance upon Administrative Agent or any other
Lender, and based on the financial statements referred to in Section 4.01(j),
Section 6.01 and Section 6.02 hereof and such other documents and information as
it has deemed appropriate, made its own credit analysis and decision to enter
into this Agreement.  Each Lender also acknowledges that it will, independently
and without reliance upon Administrative Agent or any other Lender and based on
such documents and information as it shall deem appropriate at the time,
continue to make its own credit decisions in taking or not taking action under
this Agreement and the other Loan Papers.

     9.05.  Indemnification by Lenders.  Lenders shall indemnify
Administrative Agent, pro rata in accordance with each Lender's Specified
Percentage, from and against any and all liabilities, obligations, losses,
damages, penalties, actions, judgments, suits, reasonable costs and expenses, or
disbursements of any kind or nature whatsoever which may be imposed on, incurred
by, or asserted against Administrative Agent in any way relating to or arising
out of any Loan Papers or any action taken or omitted by Administrative Agent
thereunder, including any negligence of Administrative Agent; provided, however,
                                                              --------  -------
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 Administrative Agent's gross negligence or willful
misconduct.  Without limitation of the foregoing, Lenders shall reimburse
Administrative Agent, pro rata in accordance with each Lender's Specified
Percentage, promptly upon demand for any out-of-pocket expenses (including
reasonable attorneys' fees) incurred by Administrative Agent in connection with
the preparation, execution, delivery, administration, modification, amendment,
or enforcement (whether through negotiation, legal proceedings or otherwise) of,
or legal and other advice in respect of rights or responsibilities under, the
Loan Papers.  The indemnity provided in this Section 9.05 shall survive the
termination of this Agreement.

     9.06.  Successor Administrative Agent.  Administrative Agent may resign
at any time by giving 30 days written notice thereof to Lenders and the
Borrower, and may be removed at any time with or without cause by the action of
all of the Lenders (other than Administrative Agent, if it is a Lender).   Upon
any such resignation or removal, Majority Lenders shall have the right to
appoint a successor Administrative Agent with the prior written consent of the
Borrower (which shall not be unreasonably withheld), provided that, if there
                                                     -------------
exists an Event of Default that is continuing, no consent of the Borrower shall
be required.  If no successor Administrative Agent shall have been so

                                      80
<PAGE>

appointed and shall have accepted such appointment within thirty days after the
retiring Administrative Agent's giving of notice of resignation, then the
retiring Administrative Agent may, on behalf of Lenders, appoint a successor
Administrative Agent, which shall be a commercial bank organized under the Laws
of the United States of America or of any State thereof and having a combined
capital and surplus of at least $500,000,000. Upon the acceptance of any
appointment as Administrative Agent hereunder by a successor Administrative
Agent, such successor Administrative Agent shall thereupon succeed to and become
vested with all the Rights and duties of the retiring Administrative Agent, and
the retiring Administrative Agent shall be discharged from its duties and
obligations under the Loan Papers, provided that if the retiring or removed
                                   -------------
Administrative Agent is unable to appoint a successor Administrative Agent,
Administrative Agent shall, after the expiration of a sixty day period from the
date of notice, be relieved of all obligations as Administrative Agent
hereunder. Notwithstanding any Administrative Agent's resignation or removal
hereunder, the provisions of this Article shall continue to inure to its benefit
as to any actions taken or omitted to be taken by it while it was Administrative
Agent under this Agreement.

                           ARTICLE X  MISCELLANEOUS

    10.01.  Amendments and Waivers.  No amendment or waiver of any provision
of this Agreement or any other Loan Papers, nor consent to any departure by the
Borrower or any Obligor or Restricted Subsidiary therefrom, shall be effective
unless the same shall be in writing and signed by the Borrower and the
Administrative Agent with the consent of the Majority Lenders, and then any such
waiver or consent shall be effective only in the specific instance and for the
specific purpose for which given; provided, however, that no amendment, waiver,
                                  --------  -------

definitions of "Commitment", "Maturity Date" or "Majority Lenders", or (g) amend
this Section 10.01.  No amendment, waiver, or consent shall affect the Rights or

Lenders.  Notwithstanding the foregoing provision or any provision of this
Agreement or any Loan Paper to the contrary, any provision of (i) Section
2.16(b) hereof will require the consent of the Administrative Agent and the
Majority Lenders to amend, waive or consent to departure from any provision

    (iii)  If to any Lender, to its address shown opposite its signature block
on the signature pages hereto, or on any Assignment and Acceptance, or in any
other notice to the Borrower and the Administrative Agent,

or at such other address or, telecopier or telephone number or to the attention
of such other individual or department as the party to which such information
pertains may hereafter specify for the purpose in a notice to the other
specifically captioned "Notice of Change of Address".

    (c)  Effectiveness.  Each notice to be given or delivered to any party
pursuant to this Agreement shall be effective or deemed delivered or furnished
(i) if sent by mail upon receipt, (ii) if

                                      83
<PAGE>

sent by telecopier, when such notice is transmitted to the appropriate number,
answerback received, (iii) if sent by hand delivery or overnight courier, when
received by the addressee addressed as above provided, and (iv) if given by
telephone, when communicated to the individual or any member of the department
specified as the individual or department to whose attention notices,
communications and materials are to be given or delivered except that notices of
a change of address, telecopier or telephone number or individual or department
to whose attention notices, communications and materials are to be given or
delivered shall not be effective until received; provided, however, that notices
                                                 --------  -------
to Administrative Agent pursuant to Article II shall be effective when received.
The Borrower agrees that Administrative Agent shall have no duty or obligation
to verify or otherwise confirm telephonic notices given pursuant to Article II,
and agrees to indemnify and hold harmless Administrative Agent and Lenders for
any and all liabilities, obligations, losses, damages, penalties, actions,
judgments, suits, claims, costs, and expenses resulting, directly or indirectly,
from acting upon any such notice.

    10.03.  Parties in Interest.  All covenants and agreements contained in
this Agreement and all other Loan Papers shall bind and inure to the benefit of
the respective successors and permitted  assigns of the parties hereto.  Each
Lender may from time to time assign or transfer its interests hereunder pursuant
to Section 10.04 hereof.  The Borrower may not assign or transfer its Rights or
obligations hereunder without the prior written consent of each Lender.

    10.04.  Assignments and Participations.

    (a) Each Lender (an "Assignor") may assign its Rights and obligations as a
Lender under the Loan Papers to another Lender or its Bank Affiliate, or to one
or more transferees pursuant to an Assignment and Acceptance, so long as, if
such Assignee is not another Lender or a Bank Affiliate of the Assignor (i) each
assignment shall be of a constant, and not a varying percentage of all Rights
and obligations thereunder, (ii) each Assignor shall obtain in each case the
prior written consent of Administrative Agent and the Borrower, such consent of
the Borrower not to be unreasonably withheld or delayed, provided that, in the
                                                         -------------
event there exists an Event of Default that is continuing, no consent of the
Borrower shall be required to make an assignment, (iii) each Assignor shall in
each case pay a $3,500 processing fee to Administrative Agent and (iv) no such
assignment is for an amount less than $10,000,000 (unless such Lender is
assigning all of its remaining interest) and in increments of $1,000,000 (and,
if such assignment is a partial assignment, no Lender shall hold less than
$10,000,000 immediately after giving effect to any assignment unless it assigned
all of its interest).  Within five Business Days after the Borrower receives
notice of any such assignment, the Borrower shall execute and deliver to
Administrative Agent, but only in exchange for the Notes issued to Assignor, new
Notes to the order of such Assignor and its assignee in amounts equal to their
Specified Percentages of the Commitment.  Such new Notes shall be dated the
effective date of the assignment.  It is specifically acknowledged and agreed
that on and after the effective date of each assignment, the assignee shall be a
party hereto and shall have the Rights and obligations of a Lender under the
Loan Papers.

    (b) Each Lender may sell participations to one or more Persons in all or any
of its Rights and obligations under the Loan Papers; provided, however, that (i)
                                                     --------  -------
such Lender's obligations under the Loan Papers shall remain unchanged, (ii)
such Lender shall remain solely responsible to the other parties hereto for the
performance of such obligations, (iii) such Lender shall remain the holder of
its Notes for all purposes of the Loan Papers, (iv) the participant shall be
granted the Right to vote on or consent to only those matters described in
Sections 10.01(a), (b), (c), (d), (e) and (f) hereof,

                                      84
<PAGE>

(v) Obligors, the Restricted Subsidiaries, the Administrative Agent, and other
Lenders shall continue to deal solely and directly with such Lender in
connection with their respective Rights and obligations under the Loan Papers
and (vi) no such participation is for an amount less than $5,000,000.

    (c) Any Lender may, in connection with any assignment or participation, or
proposed assignment or participation, disclose to the assignee or participant,
or proposed assignee or participant, any information relating to the Borrower
and its Subsidiaries furnished to such Lender by or on behalf of the Borrower
and its Subsidiaries, subject to the provisions of Section 10.15 hereof.

    (d) Notwithstanding any other provision set forth in this Agreement, (i) any
Lender may at any time create a security interest in all or any portion of its
Rights under this Agreement (including, without limitation, the Advances owing
to it and the Notes held by it) in favor of any Federal Reserve Bank in
accordance with Regulation A of the Board of Governors of the Federal Reserve
System and (ii) no participant of any Lender may further assign or participate
any of its interest in the Loan Papers to any Person (except as may be required
by Law or a Tribunal having authority over such participant).

    10.05.  Sharing of Payments.  If, after and during the continuance of any
Event of Default,  any Lender shall obtain any payment (whether voluntary,
involuntary, through the exercise of any Right of set-off, or otherwise) on
account of its Advances in excess of its pro rata share of payments made by the
Borrower in accordance with such Lender's Specified Percentage, such Lender
shall forthwith purchase participations in Advances made by the other Lenders as
shall be necessary to share the excess payment pro rata in accordance with each
Lender's Specified Percentage with each of them; provided, however, that if any
                                                 --------  -------
of such excess payment is thereafter recovered from the purchasing Lender, its
purchase from each Lender shall be rescinded and each Lender shall repay the
purchase price to the extent of such recovery together with a pro rata share of
any interest or other amount paid or payable by the purchasing Lender in respect
of the total amount so recovered.  The Borrower agrees that any Lender so
purchasing a participation from another Lender pursuant to this Section 10.05
may, to the fullest extent permitted by Law, exercise all its Rights of payment
(including the Right of set-off) with respect to such participation as fully as
if such Lender were the direct creditor of the Borrower in the amount of such
participation.

    10.06.  Right of Set-off.  Upon the occurrence and during the continuance
of any Event of Default, each Lender is hereby authorized (after prior written
notice to the Administrative Agent) at any time and from time to time, to the
fullest extent permitted by Law, to set-off and apply any and all deposits
(general or special, time or demand, provisional or final) at any time held and
other indebtedness at any time owing by such Lender to or for the credit or the
account of the Borrower or any of its Restricted Subsidiaries against any and
all of the obligations of the Borrower now or hereafter existing under this
Agreement and the other Loan Papers, whether or not Administrative Agent or any
Lender shall have made any demand under this Agreement or the other Loan Papers,
and even if such obligations are unmatured.  Each Lender shall promptly notify
the Borrower after any such set-off and application, provided that the failure
                                                     -------------
to give such notice shall not affect the validity of such set-off and
application.  The Rights of each Lender under this Section 10.06 are in addition
to other Rights (including, without limitation, other Rights of set-off) which
such Lender may have.

    10.07.  Costs, Expenses, and Taxes.

                                      85
<PAGE>

    (a) Notwithstanding anything to the contrary in the Loan Papers, the
Borrower agrees to pay on demand (i) all reasonable out of pocket costs and
expenses of Administrative Agent in connection with the preparation and
negotiation of all Loan Papers, including without limitation the reasonable fees
and out-of-pocket expenses of Special Counsel, FCC counsel, PUC counsel and
local counsel, as appropriate, (ii) all costs and expenses (including reasonable
attorneys' fees and expenses) of Administrative Agent in connection with any
interpretation, grant and perfection of any Lien, modification, amendment,
waiver, release of any Loan Papers, restructuring or work-out and (iii) all
costs and expenses (including reasonable attorneys' fees and expenses) of
Administrative Agent in connection with any collection of any portion of the
Obligations or the enforcement of any Loan Papers during the continuance of an
Event of Default.

    (b) In addition, notwithstanding anything to the contrary in the Loan
Papers, the Borrower shall pay any and all stamp, debt, and other Taxes payable
or determined to be payable in connection with any payment hereunder to
Administrative Agent, Arranging Agents or any Lender (but specifically excluding
any participant) (other than Taxes on the overall net income of Administrative
Agent or any Lender or franchise Taxes or Taxes on capital or capital receipts
of Administrative Agent or any Lender), or the execution, delivery, or
recordation of any Loan Papers, and agrees to save Administrative Agent and each
Lender harmless from and against any and all liabilities with respect to, or
resulting from any delay in paying or omission to pay any Taxes in accordance
with this Section 10.07, including any penalty, interest, and expenses relating
thereto.  All payments by the Borrower or any Restricted Subsidiary of the
Borrower under any Loan Papers shall be made free and clear of and without
deduction for any present or future Taxes (other than Taxes on the overall net
income of Administrative Agent or any Lender of any nature now or hereafter
existing, levied, or withheld, or franchise Taxes or Taxes on capital or capital
receipts of Administrative Agent or any Lender), including all interest,
penalties, or similar liabilities relating thereto.  If the Borrower shall be
required by Law to deduct or to withhold any Taxes from or in respect of any
amount payable hereunder (i) the amount so payable shall be increased to the
extent necessary so that, after making all required deductions and withholdings
(including Taxes on amounts payable to Administrative Agent or any Lender
pursuant to this sentence), Administrative Agent or any Lender receives an
amount equal to the sum it would have received had no such deductions or
withholdings been made, (ii) the Borrower shall make such deductions or
withholdings, and (iii) the Borrower shall pay the full amount deducted or
withheld to the relevant taxing authority in accordance with applicable Law.
Without prejudice to the survival of any other agreement of the Borrower
hereunder, the agreements and obligations of the Borrower contained in this
Section 10.07 shall survive the execution of this Agreement, termination of the
Commitment, repayment of the Obligations, satisfaction of each agreement
securing or assuring the Obligations and termination of this Agreement and each
other Loan Paper.

    10.08.  Rate Provision.  It is not the intention of any party to any Loan
Papers to make an agreement violative of the Laws of any applicable jurisdiction
relating to usury.  In no event shall any Obligor, Restricted Subsidiary or any
other Person be obligated to pay any amount in excess of the Maximum Amount.  If
Administrative Agent or any Lender ever receives, collects or applies, as
interest, any such excess, such amount which would be excessive interest shall
be deemed a partial repayment of principal and treated hereunder as such; and if
principal is paid in full, any remaining excess shall be paid to the Borrower or
the other Person entitled thereto.  In determining whether or not the interest
paid or payable, under any specific contingency, exceeds the Maximum Amount,
each Obligor, Restricted Subsidiary, Administrative Agent and each Lender shall,
to the maximum extent permitted under Applicable Laws, (a) characterize any
nonprincipal payment as an expense, fee or

                                      86
<PAGE>

premium rather than as interest, (b) exclude voluntary prepayments and the
effect thereof, and (c) amortize, prorate, allocate and spread in equal parts,
the total amount of interest throughout the entire contemplated term of the
Obligations so that the interest rate is uniform throughout the entire term of
the Obligations; provided that if the Obligations are paid and performed in full
                 -------------
prior to the end of the full contemplated term thereof, and if the interest
received for the actual period of existence thereof exceeds the Maximum Amount,
Administrative Agent or Lenders, as appropriate, shall refund to the Borrower
the amount of such excess or credit the amount of such excess against the total
principal amount owing, and, in such event, to the extent permitted by
Applicable Law, neither Administrative Agent nor any Lender shall be subject to
any penalties provided by any Laws for contracting for, charging or receiving
interest in excess of the Maximum Amount. This Section 10.08 shall control every
other provision of all agreements among the parties to the Loan Papers
pertaining to the transactions contemplated by or contained in the Loan Papers.

    10.09.  Severability.  If any provision of any Loan Paper is held to be
illegal, invalid, or unenforceable under present or future Laws during the term
thereof, such provision shall be fully severable, the appropriate Loan Paper
shall be construed and enforced as if such illegal, invalid, or unenforceable
provision had never comprised a part thereof, and the remaining provisions
thereof shall remain in full force and effect and shall not be affected by the
illegal, invalid, or unenforceable provision or by its severance therefrom.
Furthermore, in lieu of such illegal, invalid, or unenforceable provision there
shall be added automatically as a part of such Loan Paper a legal, valid, and
enforceable provision substantially similar in terms to the illegal, invalid, or
unenforceable provision as may be possible.

    10.10.  Exceptions to Covenants.  No Obligor or Restricted Subsidiary
shall be deemed to be permitted to take any action or to fail to take any action
that is permitted as an exception to any covenant in any Loan Papers, or that is
within the permissible limits of any covenant, if such action or omission would
result in a violation of any other covenant in any Loan Papers.

    10.11.  Counterparts.  This Agreement and the other Loan Papers may be
executed in any number of counterparts with different parties signing on
different counterparts, all of which taken together shall constitute one and the
same instrument.  In making proof of any such agreement, it shall not be
necessary to produce or account for any counterpart other than one signed by the
party against which enforcement is sought.

    10.12.  GOVERNING LAW; WAIVER OF JURY TRIAL.

    (a) THIS AGREEMENT AND ALL OTHER LOAN PAPERS SHALL BE DEEMED TO BE CONTRACTS
MADE IN NEW YORK, NEW YORK, AND SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE
WITH THE LAWS OF THE STATE OF NEW YORK, AND THE UNITED STATES OF AMERICA.
WITHOUT EXCLUDING ANY OTHER JURISDICTION, THE BORROWER AGREES TO SUBMIT ITSELF
TO THE JURISDICTION OF THE FEDERAL COURTS OF NEW YORK LOCATED IN NEW YORK, NEW
YORK FOR PROCEEDINGS IN CONNECTION HEREWITH.  TO THE MAXIMUM EXTENT PERMITTED BY
LAW, THE BORROWER, THE ADMINISTRATIVE AGENT AND EACH LENDER  HEREBY WAIVES ANY
RIGHT THAT IT MAY HAVE TO A TRIAL BY JURY OF ANY DISPUTE (WHETHER A CLAIM IN
TORT, CONTRACT, EQUITY, OR OTHERWISE) ARISING UNDER OR RELATING TO THIS
AGREEMENT, THE OTHER LOAN PAPERS, OR ANY RELATED MATTERS, AND

                                      87
<PAGE>

AGREES THAT ANY SUCH DISPUTE SHALL BE TRIED BEFORE A JUDGE SITTING WITHOUT A
JURY.

    (b) THE BORROWER, THE ADMINISTRATIVE AGENT AND EACH LENDER HEREBY WAIVES
PERSONAL SERVICE OF ANY LEGAL PROCESS UPON IT.  THE BORROWER, THE ADMINISTRATIVE
AGENT AND EACH LENDER AGREES THAT SERVICE OF PROCESS MAY BE MADE UPON IT BY
REGISTERED MAIL (RETURN RECEIPT REQUESTED) DIRECTED TO THE BORROWER, THE
ADMINISTRATIVE AGENT OR EACH SUCH LENDER, RESPECTIVELY, AT ITS ADDRESS
DESIGNATED FOR NOTICE UNDER THIS AGREEMENT.   NOTHING IN THIS SECTION 10.12
SHALL AFFECT THE RIGHT OF ANY PARTY TO SERVE LEGAL PROCESS IN ANY OTHER MANNER
PERMITTED BY LAW.

    10.13.  ENTIRE AGREEMENT.  THIS AGREEMENT AND THE OTHER LOAN PAPERS
REPRESENT THE FINAL AGREEMENT BETWEEN THE PARTIES AND MAY NOT BE CONTRADICTED BY
EVIDENCE OF PRIOR, CONTEMPORANEOUS OR SUBSEQUENT ORAL AGREEMENT OF THE PARTIES.
THERE ARE NO UNWRITTEN ORAL AGREEMENTS BETWEEN THE PARTIES.  THIS AGREEMENT
SUPERSEDES AND REPLACES IN ITS ENTIRETY THE COMMITMENT LETTER AGREEMENT DATED
FEBRUARY 8, 2000 INCLUDING, WITHOUT LIMITATION, THE SUMMARY OF TERMS AND
CONDITIONS DATED FEBRUARY 8, 2000.

    10.14.  Release of Conditional Early Release Unlimited Guaranty. At such
time as (i) there exists no Default under Section 8.01(a) hereof, (ii) there
exists no Event of Default and (iii) the Senior Unsecured Debt Rating is BBB- or
Baa3 or better, the Guarantor shall be immediately and automatically released
from its obligations under the Conditional Early Release Unlimited Guaranty, and
the Administrative Agent shall, and the Arranging Agents and the Lenders hereby
authorize the Administrative Agent to, promptly take all action and execute such
documents to release the Guarantor from its obligations under the Conditional
Early Release Unlimited Guaranty in full, and return the Conditional Early
Release Unlimited Guaranty to the Guarantor.

    10.15.  Confidentiality. Each Lender agrees to keep information obtained
by it pursuant to the terms hereof or the terms of any other Loan Paper that is
not otherwise publicly available ("Confidential Information") confidential in
accordance with such Lender's customary procedures for handling confidential
information of this nature and in accordance with safe and sound banking
practices and agrees that it will only use such Confidential Information in
connection with the transactions contemplated by this Agreement and not disclose
any of such Confidential Information other than (a) to such Lenders and its
Affiliates' (other than an Affiliate which is a competitor of the Borrower or
its Subsidiaries) employees, counsel (in-house and outside), accountants,
consultants, representatives, professional advisors and agents so long as such
Person is advised of the confidentiality of such Confidential Information and
the limitation on its use under this Section 10.15, needs to have knowledge of
such Confidential Information for such limited use, and, if such Person is not
such Lenders' or its Affiliates' employee, counsel (in-house and outside),
accountant consultant,  professional advisor or agent, such Person has executed
a confidentiality undertaking in favor of the Borrower substantially upon the
terms of this Section 10.15 before such Confidential Information is disclosed to
such Person, (b) to regulatory officials, and in order to comply with any
Applicable Law, or other law, regulation or judicial order, or as requested or
required by bank regulators or auditors or other governmental authorities or
Tribunals, (c) as reasonably deemed

                                      88
<PAGE>

necessary in connection with any investigation, legal process or litigation, or
(d) to assignees or participants or proposed assignees or proposed participants
of all or any part of this credit facility so long as such Person has executed a
confidentiality undertaking in favor of the Borrower substantially upon the
terms of this Section 10.15 before such Confidential Information is disclosed to
such Person. The failure of any Lender to comply with the provisions of this
Section 10.15 shall not affect the Obligations, or the obligation of the
Borrower to comply with the terms of this Agreement and the other Loan Papers,
or the validity of any assignment or participation granted pursuant to the terms
of this Agreement. Each Lender shall be responsible for any breach of the
provisions of this Section 10.15 or unauthorized disclosure of such Confidential
Information by any of its or its Affiliates' employees, counsel (in-house and
outside), accountants, consultants, representatives, professional advisors and
agents. Each Lender shall take customary precautions to prevent Confidential
Information from being disclosed to its employees or employees of any Affiliate
who are equity analysts or Persons involved in publication of research in
connection with the Borrower or any of the Borrower's Subsidiaries or any of
their respective securities.
