the Borrower and any one or more Lenders (including New Lenders) may, with the

Date and prior to April 10, 2004, agree that such Lenders shall make an
additional loan facility (the "Incremental Facility"; the commitments
thereunder, the "Incremental Commitments" and the loans thereunder, the
"Incremental Loans") available to the Borrower. Such Incremental Facility may be
documented by a supplement to this Agreement signed by the Borrower, the
Administrative Agent and the Lenders party thereto. Notwithstanding the
foregoing, without the consent of the Required Lenders, (i) the aggregate amount
of the Incremental Facility shall not exceed $250,000,000 (minus the amount of

this Agreement in connection with any transaction described in Section 2.1(c) or
2.1(d) shall execute a New Lender Supplement (each, a "New Lender Supplement"),

Borrower shall borrow Revolving Loans under the additional Revolving Commitments
provided under Section 2.1(c) above from each Lender participating in the
relevant increase in an amount determined by reference to the amount of each
Type of Loan (and, in the case of Eurodollar Loans, of each Eurodollar Tranche)
which would then have been outstanding from such Lender if (i) each such Type or
Eurodollar Tranche had been borrowed or effected on such Increased Facility
Closing Date and (ii) the aggregate amount of each such Type or Eurodollar
Tranche requested to be so borrowed or effected had been proportionately
increased. The Eurodollar Base Rate applicable to any Eurodollar Loan borrowed

Tranche (or, until the expiration of the then-current Interest Period, such
other rate as shall be agreed upon between the Borrower and the relevant
Lender).

ABR Loans, $5,000,000 or a whole multiple of $1,000,000 in excess thereof (or,
if the then aggregate Available Revolving Commitments are less than $5,000,000,
such lesser amount) and (x) in the case of Eurodollar Loans, $5,000,000 or a
whole multiple of $1,000,000 in excess thereof; provided, that the Swingline
Lender may request, on behalf of the Borrower, borrowings under the Revolving
Commitments that are ABR Loans in other amounts pursuant to Section 2.5. Each
borrowing under the Delayed-Draw Term Facility shall be in an aggregate amount
equal to (y) in the case of ABR Loans, $5,000,000 or a whole multiple of
$1,000,000 in excess thereof (or, if the then aggregate Available Delayed-Draw
Term Commitments are less than $5,000,000, such lesser amount) and (z) in the
case of Eurodollar Loans, $5,000,000 or a whole multiple of $1,000,000 in excess

to the Administrative Agent at the Funding Office an amount in immediately
available funds equal to the Loan to be made by such Lender. The Administrative
Agent shall credit the account of the Borrower on the books of such office of
the Administrative Agent with the aggregate of the amounts made available to the
Administrative Agent by the Lenders in immediately available funds.

                  (b) The Tranche B Term Loans of each Tranche B Term Lender
shall mature in 21 consecutive quarterly installments (each due on the last day
of each calendar quarter), commencing on March 31, 2003, each of which shall be
in an amount equal to such Lender's Tranche B Term Percentage multiplied by (i)
in the case of the first 20 such installments, 0.25% of the Tranche B Aggregate
Funded Amount and (ii) in the case of the last such installment (which shall be
due on March 31, 2008), 95.0% of the Tranche B Aggregate Funded Amount.

                  (c) The Total Revolving Commitments shall be permanently

                  (d) (i) Any reduction or termination of the Revolving
Commitments pursuant to this Section 2.3 shall be accompanied by prepayment of
the Revolving Loans and/or Swingline Loans to the extent that the Total
Revolving Extensions of Credit exceed the amount of the Total

<PAGE>   35
                                                                              30


Revolving Commitments after giving effect thereto, provided that if the
aggregate principal amount of Revolving Loans and Swingline Loans then
outstanding is less than the amount of such excess (because L/C Obligations
constitute a portion thereof), the Borrower shall, to the extent of the balance
of such excess, replace outstanding Letters of Credit and/or deposit an amount
in cash in a cash collateral account established with the Administrative Agent
for the benefit of the Lenders on terms and conditions satisfactory to the
Administrative Agent. The application of any prepayment pursuant to this
paragraph shall be made, first, to ABR Loans and, second, to Eurodollar Loans.
Each prepayment of the Loans under this paragraph (other than ABR Loans and
Swingline Loans) shall be accompanied by accrued interest to the date of such
prepayment on the amount prepaid.

                           (ii) The Borrower shall repay all outstanding
Revolving Loans on the Revolving Termination Date.

                  2.4. Swingline Commitment. (a) Subject to the terms and
conditions hereof, the Swingline Lender agrees to make a portion of the credit
otherwise available to the Borrower under the Revolving Commitments from time to
time during the Revolving Commitment Period by making swing line loans
("Swingline Loans") to the Borrower; provided that (i) the aggregate principal
amount of Swingline Loans outstanding at any time shall not exceed the Swingline
Commitment then in effect (notwithstanding that the Swingline Loans outstanding
at any time, when aggregated with the Swingline Lender's other outstanding
Revolving Loans hereunder, may exceed the Swingline Commitment then in effect)
and (ii) the Borrower shall not request, and the Swingline Lender shall not
make, any Swingline Loan if, after giving effect to the making of such Swingline
Loan, the aggregate amount of the Available Revolving Commitments would be less
than zero. During the Revolving Commitment Period, the Borrower may use the
Swingline Commitment by borrowing, repaying and reborrowing, all in accordance
with the terms and conditions hereof.

                  (b) The Borrower shall repay all outstanding Swingline Loans
on the Revolving Termination Date.

                  2.5. Procedure for Swingline Borrowing; Refunding of Swingline
Loans. (a) Whenever the Borrower desires that the Swingline Lender make
Swingline Loans it shall give the Swingline Lender irrevocable telephonic notice
confirmed promptly in writing (which telephonic notice must be received by the
Swingline Lender not later than 2:00 P.M., New York City time, on the proposed
Borrowing Date), specifying (i) the amount to be borrowed and (ii) the requested
Borrowing Date (which shall be a Business Day during the Revolving Commitment
Period). Each borrowing under the Swingline Commitment shall be in an amount
equal to $500,000 or a whole multiple of $100,000 in excess thereof. Not later
than 3:00 P.M., New York City time, on the Borrowing Date specified in a notice
in respect of Swingline Loans, the Swingline Lender shall make available to the
Administrative Agent at the Funding Office an amount in immediately available
funds equal to the amount of the Swingline Loan to be made by the Swingline
Lender. The Administrative Agent shall make the proceeds of such Swingline Loan
available to the Borrower on such Borrowing Date by depositing such proceeds in
the account of the Borrower with the Administrative Agent on such Borrowing Date
in immediately available funds (unless in the notice of borrowing the Borrower
gives instructions that the funds

<PAGE>   36
                                                                              31


shall be wired to another account, in which case the funds shall be so wired to
the designated account prior to 3:00 P.M., New York City time).

                  (b) The Swingline Lender, at any time and from time to time in
its sole and absolute discretion may, on behalf of the Borrower (which hereby
irrevocably directs the Swingline Lender to act on its behalf), on one Business
Day's notice given by the Swingline Lender no later than 12:00 Noon, New York
City time, request each Revolving Lender to make, and each Revolving Lender
hereby agrees to make, a Revolving Loan, in an amount equal to such Revolving
Lender's Revolving Percentage of the aggregate amount of the Swingline Loans
(the "Refunded Swingline Loans") outstanding on the date of such notice, to
repay the Swingline Lender. Each Revolving Lender shall make the amount of such
Revolving Loan available to the Administrative Agent at the Funding Office in
immediately available funds, not later than 10:00 A.M., New York City time, one
Business Day after the date of such notice. The proceeds of such Revolving Loans
shall be immediately made available by the Administrative Agent to the Swingline
Lender for application by the Swingline Lender to the repayment of the Refunded
Swingline Loans. The Borrower irrevocably authorizes the Swingline Lender to
charge the Borrower's accounts with the Administrative Agent (up to the amount
available in each such account) in order to immediately pay the amount of such
Refunded Swingline Loans to the extent amounts received from the Revolving
Lenders are not sufficient to repay in full such Refunded Swingline Loans.

                  (c) If prior to the time a Revolving Loan would have otherwise
been made pursuant to Section 2.5(b), one of the events described in Section
8(f) shall have occurred and be continuing with respect to the Borrower or if
for any other reason, as determined by the Swingline Lender in its sole
discretion, Revolving Loans may not be made as contemplated by Section 2.5(b),
each Revolving Lender shall, on the date such Revolving Loan was to have been
made pursuant to the notice referred to in Section 2.5(b) (the "Refunding
Date"), purchase for cash an undivided participating interest in the then
outstanding Swingline Loans by paying to the Swingline Lender an amount (the
"Swingline Participation Amount") equal to (i) such Revolving Lender's Revolving
Percentage times (ii) the sum of the aggregate principal amount of Swingline
Loans then outstanding that were to have been repaid with such Revolving Loans.

                  (d) Whenever, at any time after the Swingline Lender has
received from any Revolving Lender such Lender's Swingline Participation Amount,
the Swingline Lender receives any payment on account of the Swingline Loans, the
Swingline Lender will distribute to such Lender its Swingline Participation
Amount (appropriately adjusted, in the case of interest payments, to reflect the
period of time during which such Lender's participating interest was outstanding
and funded and, in the case of principal and interest payments, to reflect such
Lender's pro rata portion of such payment if such payment is not sufficient to
pay the principal of and interest on all Swingline Loans then due); provided,
however, that in the event that such payment received by the Swingline Lender is
required to be returned, such Revolving Lender will return to the Swingline
Lender any portion thereof previously distributed to it by the Swingline Lender.

                  (e) Each Revolving Lender's obligation to make the Loans
referred to in Section 2.5(b) and to purchase participating interests pursuant
to Section 2.5(c) shall be absolute and

<PAGE>   37
                                                                              32


unconditional and shall not be affected by any circumstance, including (i) any
setoff, counterclaim, recoupment, defense or other right that such Revolving
Lender or the Borrower may have against the Swingline Lender, the Borrower or
any other Person for any reason whatsoever; (ii) the occurrence or continuance
of a Default or an Event of Default or the failure to satisfy any of the other
conditions specified in Section 5; (iii) any adverse change in the condition
(financial or otherwise) of the Borrower; (iv) any breach of this Agreement or
any other Loan Document by the Borrower, any other Loan Party or any other
Revolving Lender; or (v) any other circumstance, happening or event whatsoever,
whether or not similar to any of the foregoing.

                  2.6. Commitment Fees, etc. (a) The Borrower agrees to pay to
the Administrative Agent for the account of each Revolving Lender a commitment
fee for the period from and including the Restatement Effective Date to the last
day of the Revolving Commitment Period, computed at the Commitment Fee Rate on
the average daily amount of the Available Revolving Commitment of such Lender
during the period for which payment is made, payable quarterly in arrears on the
last day of each March, June, September and December and on the Revolving
Termination Date, commencing on the first of such dates to occur after the date
hereof.

                  (b) The Borrower agrees to pay to the Administrative Agent for
the account of each Delayed-Draw Term Lender a commitment fee for the period
from and including the Restatement Effective Date to the date on which the
Delayed-Draw Term Commitments have been fully utilized or terminated, computed
at the Commitment Fee Rate on the average daily amount of the Available
Delayed-Draw Term Commitments of such Lender during the period for which payment
is made, payable quarterly in arrears on the last day of each March, June,
September and December and on the date on which the Delayed-Draw Term
Commitments have been fully utilized or terminated, commencing on the first of
such dates to occur after the date hereof.

                  (c) The Borrower agrees to pay to the Administrative Agent the
fees in the amounts and on the dates previously agreed to in writing by the
Borrower and the Administrative Agent.

                  2.7. Optional Termination or Reduction of Commitments. The
Borrower shall have the right, upon notice (or, when accompanied by a prepayment
of ABR Loans or Eurodollar Loans, not less than one or three Business Days'
notice, respectively) to the Administrative Agent, to terminate the Revolving
Commitments and Delayed-Draw Term Commitments or, from time to time, to reduce
the amount of the Revolving Commitments and Delayed-Draw Term Commitments;
provided that no such termination or reduction of Revolving Commitments shall be
permitted if, after giving effect thereto and to any prepayments of the
Revolving Loans and Swingline Loans made on the effective date thereof, the
Total Revolving Extensions of Credit would exceed the Total Revolving
Commitments. Any such reduction shall be in an amount equal to $1,000,000, or a
whole multiple thereof, and shall reduce ratably and permanently the Revolving
Commitments and Delayed-Draw Term Commitments then in effect.

<PAGE>   38
                                                                              33


                  2.8. Optional Prepayments. Subject to Section 2.9(d), the
Borrower may at any time and from time to time prepay the Loans, in whole or in
part, without premium or penalty, upon irrevocable notice delivered to the
Administrative Agent at least three Business Days prior thereto in the case of
Eurodollar Loans and at least one Business Day prior thereto in the case of ABR
Loans, which notice shall specify the date and amount of prepayment and whether
the prepayment is of Eurodollar Loans or ABR Loans; provided, that if a
Eurodollar Loan is prepaid on any day other than the last day of the Interest
Period applicable thereto, the Borrower shall also pay any amounts owing
pursuant to Section 2.18. Upon receipt of any such notice the Administrative
Agent shall promptly notify each relevant Lender thereof. If any such notice is
given, the amount specified in such notice shall be due and payable on the date
specified therein, together with (except in the case of Revolving Loans that are
ABR Loans and Swingline Loans) accrued interest to such date on the amount
prepaid. Partial prepayments of Term Loans and Revolving Loans shall be in an
aggregate principal amount of $1,000,000 or a whole multiple thereof. Partial
prepayments of Swingline Loans shall be in an aggregate principal amount of
$100,000 or a whole multiple thereof.

                  2.9. Additional Mandatory Prepayments and Commitment
Reductions. Until the date on which the ratio of Consolidated Total Debt on such
day to Annualized Consolidated EBITDA for the most recent complete fiscal
quarter of TWTC is less than 4.00 to 1.0, the following mandatory prepayment
provisions shall be applicable and the Borrower shall apply the following
amounts to prepay the Term Loans and permanently reduce the Revolving
Commitments and the Delayed-Draw Term Commitments as follows:

                  (a) Except to the extent required to refinance or replace any
bridge financings or Rollover Notes pursuant to the terms of any Additional
Financing, if any Capital Stock or Indebtedness shall be issued or incurred by
TWTC or any of its Subsidiaries (excluding any Indebtedness permitted under
Section 7.2, the Net Cash Proceeds of any issuance of TWTC's Capital Stock to
the extent used to finance the cost of capital expenditures permitted under
Section 7.7 or the business plan as described in the Confidential Information
Memorandum) after the Restatement Effective Date, 100% of the Net Cash Proceeds
thereof shall be applied on the date of such issuance or incurrence toward the
prepayment of the Term Loans and the reduction of the Revolving Commitments and
the Delayed-Draw Term Commitments as set forth in accordance with Section
2.9(d).

                  (b) If on any date TWTC or any of its Subsidiaries shall
receive Net Cash Proceeds from any Asset Sale, Exchange or Recovery Event (which
Net Cash Proceeds, in the case of a Recovery Event, exceed $1,000,000) then,
unless a Reinvestment Notice shall be delivered in respect thereof, such Net
Cash Proceeds shall be applied within three Business Days after such date toward
the prepayment of the Term Loans and the reduction of the Revolving Commitments
and the Delayed-Draw Term Commitments as set forth in Section 2.9(d); provided,
that, notwithstanding the foregoing, (i) the aggregate Net Cash Proceeds of
Asset Sales, Exchanges and Recovery Events that may be excluded from the
foregoing requirement pursuant to a Reinvestment Notice shall not exceed
$30,000,000 at any time, other than with respect to Asset Sales permitted under
Section 7.5(i), at any time (in each case, after giving effect to any actual
reinvestment of such Net Cash Proceeds in accordance with a Reinvestment Notice)
and (ii) on each Reinvestment Prepayment Date, an amount equal to the
Reinvestment

<PAGE>   39
                                                                              34


Prepayment Amount with respect to the relevant Reinvestment Event shall be
applied toward the prepayment of the Term Loans and the reduction of the
Revolving Commitments and the Delayed-Draw Term Commitments as set forth in
Section 2.9(d).

                  (c) If, for any fiscal year of TWTC commencing with the 2003
fiscal year, there shall be Excess Cash Flow, the Borrower shall, on the
relevant Excess Cash Flow Application Date, apply an amount equal to 50% of such
Excess Cash Flow toward the prepayment of the Term Loans and the reduction of
the Revolving Commitments and the Delayed-Draw Term Commitments as set forth in
Section 2.9(d). Each such prepayment and commitment reduction shall be made on a
date (an "Excess Cash Flow Application Date") no later than five Business Days
after the earlier of (i) the date on which the financial statements of TWTC
referred to in Section 6.1(a), for the fiscal year with respect to which such
prepayment is made, are required to be delivered to the Lenders and (ii) the
date such financial statements are actually delivered.

                  (d) Amounts to be applied in connection with prepayments of
Term Loans and reductions of Revolving Commitments and Delayed-Draw Term
Commitments made pursuant to Section 2.9 shall be applied, first, to the
prepayment of the Term Loans and, second, to reduce ratably and permanently the
Revolving Commitments and the Delayed-Draw Term Commitments. Any such reduction
of the Revolving Commitments shall be accompanied by prepayment of the Revolving
Loans and/or Swingline Loans to the extent, if any, that the Total Revolving
Extensions of Credit exceed the amount of the Total Revolving Commitments as so
reduced, provided that if the aggregate principal amount of Revolving Loans and
Swingline Loans then outstanding is less than the amount of such excess (because
L/C Obligations constitute a portion thereof), the Borrower shall, to the extent
of the balance of such excess, replace outstanding Letters of Credit and/or
deposit an amount in cash in a cash collateral account established with the
Administrative Agent for the benefit of the Lenders on terms and conditions
satisfactory to the Administrative Agent. The application of any prepayment
pursuant to Section 2.9 shall be made, first, to ABR Loans and, second, to
Eurodollar Loans. Each prepayment of the Loans under Section 2.9 (except in the
case of Revolving Loans that are ABR Loans and Swingline Loans) shall be
accompanied by accrued interest to the date of such prepayment on the amount
prepaid.

                  (e) Notwithstanding anything to the contrary in Section 2.8,
2.9(d) or 2.15, with respect to the amount of optional or mandatory prepayment
described in Section 2.8 and Section 2.9, respectively, that is allocated to
Tranche B Term Loans (such amount, the "Tranche B Prepayment Amount"), at any
time when Delayed-Draw Term Loans remain outstanding, the Borrower will, in lieu
of applying automatically such amount to the prepayment of Tranche B Term Loans,
as provided in Section 2.8 or Section 2.9(d), as the case may be, at least five
Business Days prior to the date on which the Borrower expects to make such
prepayment, give the Administrative Agent telephonic notice (promptly confirmed
in writing) requesting that the Administrative Agent prepare and provide to each
Tranche B Term Lender a notice (each, a "Prepayment Option Notice") as described
below. As promptly as practicable after receiving such notice from the Borrower,
the Administrative Agent will send to each Tranche B Term Lender a Prepayment
Option Notice, which shall be in the form of Exhibit F, and shall include an
offer by the Borrower to prepay the relevant Tranche B Term Loans of such Lender
by an amount equal to such Lender's Tranche B Term Percentage multiplied by the
Tranche B

<PAGE>   40
                                                                              35


Prepayment Amount on the date of such expected prepayment (each, a "Prepayment
Date"). Each Tranche B Term Lender shall give notice to the Administrative Agent
prior to the applicable Prepayment Date if it elects to accept all or any
portion of such prepayment, and each Tranche B Term Lender which has not
notified the Administrative Agent of whether or not it elects to accept such
prepayment shall be deemed to have accepted such prepayment. On the Prepayment
Date, (i) the Borrower shall pay to the relevant Tranche B Term Lenders that
have not expressly rejected their Prepayment Option Notice the amount indicated
in such Notice, and such amount shall be applied toward the prepayment of the
Tranche B Term Loans and (ii) the Borrower shall pay to the Delayed-Draw Term
Lenders an amount equal to the portion of the Tranche B Prepayment Amount
expressly rejected by the relevant Tranche B Term Lenders, and such amount shall
be applied toward the prepayment of the Delayed-Draw Term Loans.

                  2.10. Conversion and Continuation Options. (a) The Borrower
may elect from time to time to convert Eurodollar Loans to ABR Loans by giving
the Administrative Agent at least two Business Days' prior irrevocable notice of
such election, provided that any such conversion of Eurodollar Loans may only be
made on the last day of an Interest Period with respect thereto. The Borrower
may elect from time to time to convert ABR Loans to Eurodollar Loans by giving
the Administrative Agent at least three Business Days' prior irrevocable notice
of such election (which notice shall specify the length of the initial Interest
Period therefor), provided that no ABR Loan may be converted into a Eurodollar
Loan when any Event of Default has occurred and is continuing and the
Administrative Agent has or the Majority Facility Lenders in respect of such
Facility have determined in its or their sole discretion not to permit such
conversions. Upon receipt of any such notice the Administrative Agent shall
promptly notify each relevant Lender thereof.

                  (a) Any Eurodollar Loan may be continued as such upon the
expiration of the then current Interest Period with respect thereto by the
Borrower giving irrevocable notice to the Administrative Agent, in accordance
with the applicable provisions of the term "Interest Period" set forth in
Section 1.1, of the length of the next Interest Period to be applicable to such
Loans, provided that no Eurodollar Loan may be continued as such when any Event
of Default has occurred and is continuing and the Administrative Agent has or
the Majority Facility Lenders in respect of such Facility have determined in its
or their sole discretion not to permit such continuations, and provided,
further, that if the Borrower shall fail to give any required notice as
described above in this paragraph or if such continuation is not permitted
pursuant to the preceding proviso such Loans shall be automatically converted to
ABR Loans on the last day of such then expiring Interest Period. Upon receipt of
any such notice the Administrative Agent shall promptly notify each relevant
Lender thereof.

                  2.11. Limitations on Eurodollar Loans. Notwithstanding
anything to the contrary in this Agreement, all borrowings, conversions and
continuations of Eurodollar Loans hereunder and all selections of Interest
Periods hereunder shall be in such amounts and be made pursuant to such
elections so that, (a) after giving effect thereto, the aggregate principal
amount of the Eurodollar Loans comprising each Eurodollar Tranche shall be equal
to $5,000,000 or a whole multiple of $1,000,000 in excess thereof and (b) no
more than 20 Eurodollar Tranches shall be outstanding at any one time.

<PAGE>   41
                                                                              36


                  2.12. Interest Rates and Payment Dates. (a) Each Eurodollar
Loan shall bear interest for each day during each Interest Period with respect
thereto at a rate per annum equal to the Eurodollar Rate determined for such day
plus the Applicable Margin.

                  (b) Each ABR Loan shall bear interest at a rate per annum
equal to the ABR plus the Applicable Margin.

                  (c) (i) If all or a portion of the principal amount of any
Loan or Reimbursement Obligation shall not be paid when due (whether at the
stated maturity, by acceleration or otherwise), such overdue amount shall bear
interest at a rate per annum equal to (x) in the case of the Loans, the rate
that would otherwise be applicable thereto pursuant to the foregoing provisions
of this Section plus 2% or (y) in the case of Reimbursement Obligations, the
rate applicable to ABR Loans under the Revolving Facility plus 2%, and (ii) if
all or a portion of any interest payable on any Loan or Reimbursement Obligation
or any commitment fee or other amount payable hereunder shall not be paid when
due (whether at the stated maturity, by acceleration or otherwise), such overdue
amount shall bear interest at a rate per annum equal to the rate then applicable
to ABR Loans under the relevant Facility plus 2% (or, in the case of any such
other amounts that do not relate to a particular Facility, the rate then
applicable to ABR Loans under the Revolving Facility plus 2%), in each case,
with respect to clauses (i) and (ii) above, from the date of such non-payment
until such amount is paid in full (as well after as before judgment).

                  (d) Interest shall be payable in arrears on each Interest
Payment Date, provided that interest accruing pursuant to paragraph (c) of this
Section shall be payable from time to time on demand.

                  2.13. Computation of Interest and Fees. (a) Interest and fees
payable pursuant hereto shall be calculated on the basis of a 360-day year for
the actual days elapsed, except that, with respect to ABR Loans the rate of
interest on which is calculated on the basis of the Prime Rate, the interest
thereon shall be calculated on the basis of a 365- (or 366-, as the case may be)
day year for the actual days elapsed. The Administrative Agent shall as soon as
practicable notify the Borrower and the relevant Lenders of each determination
of a Eurodollar Rate. Any change in the interest rate on a Loan resulting from a
change in the ABR or the Eurocurrency Reserve Requirements shall become
effective as of the opening of business on the day on which such change becomes
effective. The Administrative Agent shall as soon as practicable notify the
Borrower and the relevant Lenders of the effective date and the amount of each
such change in interest rate.

                  (b) Each determination of an interest rate by the
Administrative Agent pursuant to any provision of this Agreement shall be
conclusive and binding on the Borrower and the Lenders in the absence of
manifest error. The Administrative Agent shall, at the request of the Borrower,
deliver to the Borrower a statement showing the quotations used by the
Administrative Agent in determining any interest rate pursuant to Section 2.12.

                  2.14. Inability to Determine Interest Rate. If prior to the
first day of any Interest Period:

                                                                              37


                  (a) the Administrative Agent shall have determined (which
         determination shall be conclusive and binding upon the Borrower) that,
         by reason of circumstances affecting the relevant market, adequate and
         reasonable means do not exist for ascertaining the Eurodollar Rate for
         such Interest Period, or

                  (b) the Administrative Agent shall have received notice from
         the Required Lenders that the Eurodollar Rate determined or to be
         determined for such Interest Period will not adequately and fairly
         reflect the cost to such Lenders (as conclusively certified by such
         Lenders) of making or maintaining their affected Loans during such
         Interest Period,

the Administrative Agent shall give telecopy or telephonic notice thereof to the
Borrower and the relevant Lenders as soon as practicable thereafter. If such
notice is given (x) either the Borrower may withdraw any request for a borrowing
of Eurodollar Loans or any Eurodollar Loans requested to be made on the first
day of such Interest Period shall be made as ABR Loans, (y) any Loans that were
to have been converted on the first day of such Interest Period to Eurodollar
Loans shall be continued as ABR Loans and (z) any outstanding Eurodollar Loans
shall be converted, on the last day of the then-current Interest Period, to ABR
Loans. Until such notice has been withdrawn by the Administrative Agent, no
further Eurodollar Loans shall be made or continued as such, nor shall the
Borrower have the right to convert Loans to Eurodollar Loans.

                  2.15. Pro Rata Treatment and Payments. (a) Each borrowing by
the Borrower from the Lenders hereunder, each payment by the Borrower on account
of any commitment fee and any reduction of the Commitments of the Lenders shall
be made pro rata according to the respective Delayed-Draw Term Percentages,
Tranche B Term Percentages or Revolving Percentages, as the case may be, of the
relevant Lenders.

                  (b) Each payment other than an optional prepayment (including
each mandatory prepayment) by the Borrower on account of principal of and
interest on the Term Loans shall be made pro rata according to the respective
outstanding principal amounts of the Term Loans then held by the Term Lenders
(except as otherwise provided in Section 2.9(e)). The amount of each mandatory
principal prepayment of the Term Loans shall be applied to reduce the then
remaining installments of the Delayed-Draw Term Loans and Tranche B Term Loans,
as the case may be, pro rata based upon the then remaining principal amount
thereof. Notwithstanding anything to the contrary herein, each optional
prepayment of the Delayed-Draw Term Loans and Tranche B Term Loans shall be
applied first, towards the next scheduled installment payment of such Term Loans
pursuant to Section 2.3 and second, to reduce the then remaining installments of
such Term Loans pro rata based upon the then remaining principal amount thereof.
Amounts paid on account of the Term Loans may not be reborrowed.

                  (c) Each payment (including each prepayment) by the Borrower
on account of principal of and interest on the Revolving Loans shall be made pro
rata according to the respective outstanding principal amounts of the Revolving
Loans then held by the Revolving Lenders.

                                                                              38


                  (d) All payments (including prepayments) to be made by the
Borrower hereunder, whether on account of principal, interest, fees or
otherwise, shall be made without setoff or counterclaim and shall be made prior
to 12:00 Noon, New York City time, on the due date thereof to the Administrative
Agent, for the account of the Lenders, at the Funding Office, in Dollars and in
immediately available funds. The Administrative Agent shall distribute such
payments to the Lenders promptly upon receipt in like funds as received. If any
payment hereunder (other than payments on the Eurodollar Loans) becomes due and
payable on a day other than a Business Day, such payment shall be extended to
the next succeeding Business Day. If any payment on a Eurodollar Loan becomes
due and payable on a day other than a Business Day, the maturity thereof shall
be extended to the next succeeding Business Day unless the result of such
extension would be to extend such payment into another calendar month, in which
event such payment shall be made on the immediately preceding Business Day. In
the case of any extension of any payment of principal pursuant to the preceding
two sentences, interest thereon shall be payable at the then applicable rate
during such extension.

                  (e) Unless the Administrative Agent shall have been notified
in writing by any Lender prior to a borrowing that such Lender will not make the
amount that would constitute its share of such borrowing available to the
Administrative Agent, the Administrative Agent may assume that such Lender is
making such amount available to the Administrative Agent, and the Administrative
Agent may, in reliance upon such assumption, make available to the Borrower a
corresponding amount. If such amount is not made available to the Administrative
Agent by the required time on the Borrowing Date therefor, such Lender shall pay
to the Administrative Agent, on demand, such amount with interest thereon at a
rate equal to the daily average Federal Funds Effective Rate for the period
until such Lender makes such amount immediately available to the Administrative
Agent. A certificate of the Administrative Agent submitted to any Lender with
respect to any amounts owing under this paragraph shall be conclusive in the
absence of manifest error. If such Lender's share of such borrowing is not made
available to the Administrative Agent by such Lender within three Business Days
of such Borrowing Date, the Administrative Agent shall also be entitled to
recover such amount with interest thereon at the rate per annum applicable to
ABR Loans under the relevant Facility, on demand, from the Borrower.

                  (f) Unless the Administrative Agent shall have been notified
in writing by the Borrower prior to the date of any payment being made hereunder
that the Borrower will not make such payment to the Administrative Agent, the
Administrative Agent may assume that the Borrower is making such payment, and
the Administrative Agent may, but shall not be required to, in reliance upon
such assumption, make available to the Lenders their respective pro rata shares
of a corresponding amount. If such payment is not made to the Administrative
Agent by the Borrower within three Business Days of such required date, the
Administrative Agent shall be entitled to recover, on demand, from each Lender
to which any amount which was made available pursuant to the preceding sentence,
such amount with interest thereon at the rate per annum equal to the daily
average Federal Funds Effective Rate. Nothing herein shall be deemed to limit
the rights of the Administrative Agent or any Lender against the Borrower.

                  2.16. Requirements of Law. (a) If the adoption of or any
change in any Requirement of Law or in the interpretation or application thereof
or compliance by any Lender

<PAGE>   44
                                                                              39


with any request or directive (whether or not having the force of law) from any
central bank or other Governmental Authority made subsequent to the date hereof:

                  (i) shall subject any Lender to any tax of any kind whatsoever
         with respect to this Agreement, any Letter of Credit, any Application
         or any Eurodollar Loan made by it, or change the basis of taxation of
         payments to such Lender in respect thereof (except for Non-Excluded
         Taxes covered by Section 2.17 and changes in the rate of tax on the
         overall net income of such Lender);

                  (ii) shall impose, modify or hold applicable any reserve,
         special deposit, compulsory loan or similar requirement against assets
         held by, deposits or other liabilities in or for the account of,
         advances, loans or other extensions of credit by, or any other
         acquisition of funds by, any office of such Lender that is not
         otherwise included in the determination of the Eurodollar Rate
         hereunder; or

                  (iii) shall impose on such Lender any other condition;

and the result of any of the foregoing is to increase the cost to such Lender,
by an amount that such Lender deems to be material, of making, converting into,
continuing or maintaining Eurodollar Loans or issuing or participating in
Letters of Credit, or to reduce any amount receivable hereunder in respect
thereof, then, in any such case, the Borrower shall promptly pay such Lender,
upon its demand, any additional amounts necessary to compensate such Lender for
such increased cost actually incurred or reduced amount actually received. If
any Lender becomes entitled to claim any additional amounts pursuant to this
paragraph, it shall promptly (and, in any event, within three months) notify the
Borrower (with a copy to the Administrative Agent) of the event by reason of
which it has become so entitled.

                  (b) If any Lender shall have determined that the adoption of
or any change in any Requirement of Law regarding capital adequacy or in the
interpretation or application thereof or compliance by such Lender or any
corporation controlling such Lender with any request or directive regarding
capital adequacy (whether or not having the force of law) from any Governmental
Authority made subsequent to the date hereof shall have the effect of reducing
the rate of return on such Lender's or such corporation's capital as a
consequence of its obligations hereunder or under or in respect of any Letter of
Credit to a level below that which such Lender or such corporation could have
achieved but for such adoption, change or compliance (taking into consideration
such Lender's or such corporation's policies with respect to capital adequacy)
by an amount deemed by such Lender to be material, then from time to time, after
submission by such Lender to the Borrower (with a copy to the Administrative
Agent) of a written request therefor, the Borrower shall pay to such Lender such
additional amount or amounts as will compensate such Lender for such reduction;
provided that the Borrower shall not be required to compensate a Lender pursuant
to this paragraph for any amounts incurred more than 90 days prior to the date
that such Lender notifies the Borrower of such Lender's intention to claim
compensation therefor; and provided further that, if the circumstances giving
rise to such claim have a retroactive effect, then such 90-day period shall be
extended to include the period of such retroactive effect.

                  (c) A certificate, setting forth a reasonably detailed
explanation as to the reason for any additional amounts payable pursuant to this
Section, as to any additional amounts payable pursuant to this Section submitted
by any Lender to the Borrower (with a copy to the Administrative Agent) shall be
conclusive in the absence of manifest error. The obligations of the Borrower
pursuant to this Section shall survive the termination of this Agreement and the
payment of the Loans and all other amounts payable hereunder.

                  2.17. Taxes. (a) All payments made by the Borrower under this
Agreement shall be made free and clear of, and without deduction or withholding
for or on account of, any present or future income, stamp or other taxes,
levies, imposts, duties, charges, fees, deductions or withholdings, now or
hereafter imposed, levied, collected, withheld or assessed by any Governmental
Authority, excluding net income taxes and franchise taxes (imposed in lieu of
net income taxes) imposed on the Administrative Agent or any Lender as a result
of a present or former connection between the Administrative Agent or such
Lender and the jurisdiction of the Governmental Authority imposing such tax or
any political subdivision or taxing authority thereof or therein (other than any
such connection arising solely from the Administrative Agent or such Lender
having executed, delivered or performed its obligations or received a payment
under, or enforced, this Agreement or any other Loan Document). If any such
non-excluded taxes, levies, imposts, duties, charges, fees, deductions or
withholdings ("Non-Excluded Taxes") or Other Taxes are required to be withheld
from any amounts payable to the Administrative Agent or any Lender hereunder,
the amounts so payable to the Administrative Agent or such Lender shall be
increased to the extent necessary to yield to the Administrative Agent or such
Lender (after payment of all Non-Excluded Taxes and Other Taxes) interest or any
such other amounts payable hereunder at the rates or in the amounts specified in
this Agreement, provided, however, that the Borrower shall not be required to
increase any such amounts payable to any Lender with respect to any Non-Excluded
Taxes (i) that are attributable to such Lender's failure to comply with the
requirements of paragraph (d) or (e) of this Section or (ii) that are United
States withholding taxes imposed on amounts payable to such Lender at the time
the Lender becomes a party to this Agreement, except to the extent that such
Lender's assignor (if any) was entitled, at the time of assignment, to receive
additional amounts from the Borrower with respect to such Non-Excluded Taxes
pursuant to this paragraph.

                  (b) In addition, the Borrower shall pay any Other Taxes to the
relevant Governmental Authority in accordance with applicable law.

                  (c) Whenever any Non-Excluded Taxes or Other Taxes are payable
by the Borrower, as promptly as possible thereafter the Borrower shall send to
the Administrative Agent for its own account or for the account of the relevant
Lender, as the case may be, a certified copy of an original official receipt
received by the Borrower showing payment thereof. If the Borrower fails to pay
any Non-Excluded Taxes or Other Taxes when due to the appropriate taxing
authority or fails to remit to the Administrative Agent the required receipts or
other required documentary evidence, the Borrower shall indemnify the
Administrative Agent and the Lenders for any incremental taxes, interest or
penalties that may become payable by the Administrative Agent or any Lender as a
result of any such failure.

                                                                              41


                  (d) Each Lender (or Transferee) that is not a "U.S. Person" as
defined in Section 7701(a)(30) of the Code (a "Non-U.S. Lender") shall deliver
to the Borrower and the Administrative Agent (or, in the case of a Participant,
to the Lender from which the related participation shall have been purchased)
two copies of either U.S. Internal Revenue Service Form W-8BEN or Form W-8ECI,
or, in the case of a Non-U.S. Lender claiming exemption from U.S. federal
withholding tax under Section 871(h) or 881(c) of the Code with respect to
payments of "portfolio interest", a statement substantially in the form of
Exhibit G and a Form W-8BEN, or any subsequent versions thereof or successors
thereto, properly completed and duly executed by such Non-U.S. Lender claiming
complete exemption from, or a reduced rate of, U.S. federal withholding tax on
all payments by the Borrower under this Agreement and the other Loan Documents.
Such forms shall be delivered by each Non-U.S. Lender on or before the date it
becomes a party to this Agreement (or, in the case of any Participant, on or
before the date such Participant purchases the related participation). In
addition, each Non-U.S. Lender shall deliver such forms promptly upon the
obsolescence or invalidity of any form previously delivered by such Non-U.S.
Lender. Each Non-U.S. Lender shall promptly notify the Borrower at any time it
determines that it is no longer in a position to provide any previously
delivered certificate to the Borrower (or any other form of certification
adopted by the U.S. taxing authorities for such purpose). Notwithstanding any
other provision of this paragraph, a Non-U.S. Lender shall not be required to
deliver any form pursuant to this paragraph that such Non-U.S. Lender is not
legally able to deliver.

                  (e) A Lender that is entitled to an exemption from or
reduction of non-U.S. withholding tax under the law of the jurisdiction in which
the Borrower is located, or any treaty to which such jurisdiction is a party,
with respect to payments under this Agreement shall deliver to the Borrower
(with a copy to the Administrative Agent), at the time or times prescribed by
applicable law or reasonably requested by the Borrower, such properly completed
and executed documentation prescribed by applicable law as will permit such
payments to be made without withholding or at a reduced rate, provided that such
Lender is legally entitled to complete, execute and deliver such documentation
and in such Lender's judgment such completion, execution or submission would not
materially prejudice the legal position of such Lender.

                  (f) If any payee receives a refund of any Non-Excluded Taxes
or Other Taxes paid by the Borrower under this Section 2.17, which refund in the
sole judgment of such payee is allocable to such payment, such payee shall
promptly pay over to the Borrower the amount of such refund, net of all
out-of-pocket expenses of such payee; provided, however, that the Borrower, upon
the request of such payee, agrees to repay the amount paid over to the Borrower
to such payee in the event such Lender or the Administrative Agent is required
to repay such refund.

                  (g) The agreements in this Section shall survive the
termination of this Agreement and the payment of the Loans and all other amounts
payable hereunder.

                  2.18. Indemnity. The Borrower agrees to indemnify each Lender
and to hold each Lender harmless from any loss or expense that such Lender may
sustain or incur as a consequence of (a) default by the Borrower in making a
borrowing of, conversion into or continuation of Eurodollar Loans after the
Borrower has given a notice requesting the same in

<PAGE>   47
                                                                              42


accordance with the provisions of this Agreement, (b) default by the Borrower in
making any prepayment of or conversion from Eurodollar Loans after the Borrower
has given a notice thereof in accordance with the provisions of this Agreement
or (c) the making of a prepayment of Eurodollar Loans on a day that is not the
last day of an Interest Period with respect thereto. Such indemnification may
include an amount equal to the excess, if any, of (i) the amount of interest
that would have accrued on the amount so prepaid, or not so borrowed, converted
or continued, for the period from the date of such prepayment or of such failure
to borrow, convert or continue to the last day of such Interest Period (or, in
the case of a failure to borrow, convert or continue, the Interest Period that
would have commenced on the date of such failure) in each case at the applicable
rate of interest for such Loans provided for herein (excluding, however, the
Applicable Margin included therein, if any) over (ii) the amount of interest (as
reasonably determined by such Lender) that would have accrued to such Lender on
such amount by placing such amount on deposit for a comparable period with
leading banks in the interbank eurodollar market. A certificate as to any
amounts payable pursuant to this Section submitted to the Borrower by any Lender
shall be conclusive in the absence of manifest error. This covenant shall
survive the termination of this Agreement and the payment of the Loans and all
other amounts payable hereunder.

                  2.19. Change of Lending Office. Each Lender agrees that, upon
the occurrence of any event giving rise to the operation of Section 2.16 or
2.17(a) with respect to such Lender, it will, if requested by the Borrower, use
reasonable efforts (subject to overall policy considerations of such Lender) to
designate another lending office for any Loans affected by such event with the
object of avoiding the consequences of such event; provided, that such
designation is made on terms that, in the sole judgment of such Lender, cause
such Lender and its lending office(s) to suffer no economic, legal or regulatory
disadvantage, and provided, further, that nothing in this Section shall affect
or postpone any of the obligations of any Borrower or the rights of any Lender
pursuant to Section 2.16 or 2.17(a).

                  2.20. Replacement of Lenders. The Borrower shall be permitted
to replace any Lender that (a) requests reimbursement for amounts owing pursuant
to Section 2.16 or 2.17(a) or (b) defaults in its obligation to make Loans
hereunder, with a replacement financial institution; provided that (i) such
replacement does not conflict with any Requirement of Law, (ii) no Event of
Default shall have occurred and be continuing at the time of such replacement,
(iii) prior to any such replacement, such Lender shall not have eliminated,
after requested to do so by the Borrower, the continued need for payment of
amounts owing pursuant to Section 2.16 or 2.17(a), (iv) the replacement
financial institution shall purchase, at par, all Loans and other amounts owing
to such replaced Lender on or prior to the date of replacement, (v) the Borrower
shall be liable to such replaced Lender under Section 2.18 if any Eurodollar
Loan owing to such replaced Lender shall be purchased other than on the last day
of the Interest Period relating thereto, (vi) the replacement financial
institution, if not already a Lender, shall be reasonably satisfactory to the
Administrative Agent, (vii) the replaced Lender shall be obligated to make such
replacement in accordance with the provisions of Section 10.6 (provided that the
Borrower shall be obligated to pay the registration and processing fee referred
to therein), (viii) until such time as such replacement shall be consummated,
the Borrower shall pay all additional amounts (if any) required pursuant to
Section 2.16 or 2.17(a), as the case may be, and (ix) any such

<PAGE>   48
                                                                              43


replacement shall not be deemed to be a waiver of any rights that the Borrower,
the Administrative Agent or any other Lender shall have against the replaced
Lender.

                          SECTION 3. LETTERS OF CREDIT

                  3.1. L/C Commitment. (a) Subject to the terms and conditions
hereof, the Issuing Lender, in reliance on the agreements of the other Revolving
Lenders set forth in Section 3.4(a), agrees to issue letters of credit ("Letters
of Credit") for the account of the Borrower on any Business Day during the
Revolving Commitment Period in such form as may be approved from time to time by
the Issuing Lender; provided that the Issuing Lender shall not issue any Letter
of Credit if, after giving effect to such issuance, (i) the L/C Obligations
would exceed the L/C Commitment or (ii) the aggregate amount of the Available
Revolving Commitments would be less than zero. Each Letter of Credit shall (i)
be denominated in Dollars, (ii) have a face amount of at least $500,000 (unless
otherwise agreed by the Issuing Lender) and (iii) expire no later than the
earlier of (x) the first anniversary of its date of issuance and (y) the date
that is five Business Days prior to the Revolving Termination Date, provided
that any Letter of Credit with a one-year term may provide for the renewal
thereof for additional one-year periods (which shall in no event extend beyond
the date referred to in clause (y) above).

                  (b) The Issuing Lender shall not issue any Letter of Credit
hereunder if such issuance would conflict with, or cause the Issuing Lender or
any L/C Participant to exceed any limits imposed by, any applicable Requirement
of Law.

                  3.2. Procedure for Issuance of Letter of Credit. The Borrower
may from time to time request that the Issuing Lender issue a Letter of Credit
by delivering to the Issuing Lender at its address for notices specified herein
an Application therefor, completed to the satisfaction of the Issuing Lender,
and such other certificates, documents and other papers and information as the
Issuing Lender may request. Upon receipt of any Application, the Issuing Lender
will process such Application and the certificates, documents and other papers
and information delivered to it in connection therewith in accordance with its
customary procedures and shall promptly issue the Letter of Credit requested
thereby (but in no event shall the Issuing Lender be required to issue any
Letter of Credit earlier than three Business Days after its receipt of the
Application therefor and all such other certificates, documents and other papers
and information relating thereto) by issuing the original of such Letter of
Credit to the beneficiary thereof or as otherwise may be agreed to by the
Issuing Lender and the Borrower. The Issuing Lender shall furnish a copy of such
Letter of Credit to the Borrower or at its direction promptly following the
issuance thereof. The Issuing Lender shall promptly furnish to the
Administrative Agent, which shall in turn promptly furnish to the Lenders,
notice of the issuance of each Letter of Credit (including the amount thereof).

                  3.3. Fees and Other Charges. (a) The Borrower will pay a fee
on all outstanding Letters of Credit at a per annum rate equal to the Applicable
Margin then in effect with respect to Eurodollar Loans under the Revolving
Facility, shared ratably among the Revolving Lenders and payable quarterly in
arrears on each L/C Fee Payment Date after the issuance date. In addition, the
Borrower shall pay to the Issuing Lender for its own account a

<PAGE>   49
                                                                              44


fronting fee of 0.25% per annum on the undrawn and unexpired amount of each
Letter of Credit, payable quarterly in arrears on each L/C Fee Payment Date
after the issuance date.

                  (b) In addition to the foregoing fees, the Borrower shall pay
or reimburse the Issuing Lender for such normal and customary costs and expenses
as are incurred or charged by the Issuing Lender in issuing, negotiating,
effecting payment under, amending or otherwise administering any Letter of
Credit.

                  3.4. L/C Participations. (a) The Issuing Lender irrevocably
agrees to grant and hereby grants to each L/C Participant, and, to induce the
Issuing Lender to issue Letters of Credit hereunder, each L/C Participant
irrevocably agrees to accept and purchase and hereby accepts and purchases from
the Issuing Lender, on the terms and conditions set forth below, for such L/C
Participant's own account and risk an undivided interest equal to such L/C
Participant's Revolving Percentage in the Issuing Lender's obligations and
rights under and in respect of each Letter of Credit issued hereunder and the
amount of each draft paid by the Issuing Lender thereunder. Each L/C Participant
unconditionally and irrevocably agrees with the Issuing Lender that, if a draft
is paid under any Letter of Credit for which the Issuing Lender is not
reimbursed in full by the Borrower in accordance with the terms of this
Agreement, such L/C Participant shall pay to the Issuing Lender upon demand at
the Issuing Lender's address for notices specified herein an amount equal to
such L/C Participant's Revolving Percentage of the amount of such draft, or any
part thereof, that is not so reimbursed.

                  (b) If any amount required to be paid by any L/C Participant
to the Issuing Lender pursuant to Section 3.4(a) in respect of any unreimbursed
portion of any payment made by the Issuing Lender under any Letter of Credit is
paid to the Issuing Lender within three Business Days after the date such
payment is due, such L/C Participant shall pay to the Issuing Lender on demand
an amount equal to the product of (i) such amount, times (ii) the daily average
Federal Funds Effective Rate during the period from and including the date such
payment is required to the date on which such payment is immediately available
to the Issuing Lender, times (iii) a fraction the numerator of which is the
number of days that elapse during such period and the denominator of which is
360. If any such amount required to be paid by any L/C Participant pursuant to
Section 3.4(a) is not made available to the Issuing Lender by such L/C
Participant within three Business Days after the date such payment is due, the
Issuing Lender shall be entitled to recover from such L/C Participant, on
demand, such amount with interest thereon calculated from such due date at the
rate per annum applicable to ABR Loans under the Revolving Facility. A
certificate of the Issuing Lender submitted to any L/C Participant with respect
to any amounts owing under this Section shall be conclusive in the absence of
manifest error.

                  (c) Whenever, at any time after the Issuing Lender has made
payment under any Letter of Credit and has received from any L/C Participant its
pro rata share of such payment in accordance with Section 3.4(a), the Issuing
Lender receives any payment related to such Letter of Credit (whether directly
from the Borrower or otherwise, including proceeds of collateral applied thereto
by the Issuing Lender), or any payment of interest on account thereof, the
Issuing Lender will distribute to such L/C Participant its pro rata share
thereof; provided, however, that in the event that any such payment received by
the Issuing Lender shall be required to be

returned by the Issuing Lender, such L/C Participant shall return to the Issuing
Lender the portion thereof previously distributed by the Issuing Lender to it.

                  3.5. Reimbursement Obligation of the Borrower. The Borrower
agrees to reimburse the Issuing Lender on each date on which the Issuing Lender
notifies the Borrower of the date and amount of a draft presented under any
Letter of Credit and paid by the Issuing Lender for the amount of (a) such draft
so paid and (b) any taxes, fees, charges or other costs or expenses incurred by
the Issuing Lender in connection with such payment. Each such payment shall be
made to the Issuing Lender at its address for notices specified herein in lawful
money of the United States and in immediately available funds. Interest shall be
payable on any and all amounts remaining unpaid by the Borrower under this
Section from the date such amounts become payable (whether at stated maturity,
by acceleration or otherwise) until payment in full at the rate set forth in (i)
until the second Business Day following the date of the applicable drawing,
Section 2.12(b) and (ii) thereafter, Section 2.12(c).

                  3.6. Obligations Absolute. The Borrower's obligations under
this Section 3 shall be absolute and unconditional under any and all
circumstances and irrespective of any setoff, counterclaim or defense to payment
that the Borrower may have or have had against the Issuing Lender, any
beneficiary of a Letter of Credit or any other Person. The Borrower also agrees
with the Issuing Lender that the Issuing Lender shall not be responsible for,
and the Borrower's Reimbursement Obligations under Section 3.5 shall not be
affected by, among other things, the validity or genuineness of documents or of
any endorsements thereon, even though such documents shall in fact prove to be
invalid, fraudulent or forged, or any dispute between or among the Borrower and
any beneficiary of any Letter of Credit or any other party to which such Letter
of Credit may be transferred or any claims whatsoever of the Borrower against
any beneficiary of such Letter of Credit or any such transferee. The Issuing
Lender shall not be liable for any error, omission, interruption or delay in
transmission, dispatch or delivery of any message or advice, however
transmitted, in connection with any Letter of Credit, except for errors or
omissions found by a final and nonappealable decision of a court of competent
jurisdiction to have resulted from the gross negligence or willful misconduct of
the Issuing Lender. The Borrower agrees that any action taken or omitted by the
Issuing Lender under or in connection with any Letter of Credit or the related
drafts or documents, if done in the absence of gross negligence or willful
misconduct and in accordance with the standards of care specified in the Uniform
Commercial Code of the State of New York, shall be binding on the Borrower and
shall not result in any liability of the Issuing Lender to the Borrower.

                  3.7. Letter of Credit Payments. If any draft shall be
presented for payment under any Letter of Credit, the Issuing Lender shall
promptly notify the Borrower of the date and amount thereof. The responsibility
of the Issuing Lender to the Borrower in connection with any draft presented for
payment under any Letter of Credit shall, in addition to any payment obligation
expressly provided for in such Letter of Credit, be limited to determining that
the documents (including each draft) delivered under such Letter of Credit in
connection with such presentment are substantially in conformity with such
Letter of Credit.

                  3.8. Applications. To the extent that any provision of any
Application related to any Letter of Credit is inconsistent with the provisions
of this Section 3, the provisions of this Section 3 shall apply.

                   SECTION 4. REPRESENTATIONS AND WARRANTIES

                  To induce the Administrative Agent and the Lenders to enter
into this Agreement and to make the Loans and issue or participate in the
Letters of Credit, TWTC and the Borrower hereby jointly and severally represent
and warrant to the Administrative Agent and each Lender that:

                  4.1. Financial Condition. (a) The unaudited pro forma
consolidated balance sheet of TWTC and its consolidated Subsidiaries as at June
30, 2000 (including the notes thereto) (the "Pro Forma Balance Sheet"), copies
of which have heretofore been furnished to each Lender, has been prepared giving
effect (as if such events had occurred on such date) to (i) the consummation of
the Acquisition, (ii) the Loans expected to be made on the Restatement Effective
Date as of the date on which the Pro Forma Balance Sheet was delivered and
certain Additional Financing in connection with the Acquisition and/or the
business plan of TWTC as described in the Confidential Information Memorandum
and the use of proceeds thereof and (iii) the payment of fees and expenses in
connection with the foregoing. The Pro Forma Balance Sheet has been prepared
based on information and assumptions believed by TWTC to be reasonable as of the
date of delivery thereof, and presents fairly, based on such information and
assumptions, on a pro forma basis the estimated financial position of TWTC and
its consolidated Subsidiaries as at June 30, 2000, assuming that the events
specified in the preceding sentence had actually occurred at such date.

                  (b) The audited consolidated balance sheets of TWTC as at
December 31, 1998 and December 31, 1999, and the related consolidated statements
of income and of cash flows for the fiscal years ended on such dates, reported
on by and accompanied by an unqualified report from Ernst & Young LLP, present
fairly the consolidated financial condition of TWTC as at such date, and the
consolidated results of its operations and its consolidated cash flows for the
respective fiscal years then ended. The unaudited consolidated balance sheet of
TWTC as at June 30, 2000, and the related unaudited consolidated statements of
income and cash flows for the six-month period ended on such date, present
fairly the consolidated financial condition of TWTC as at such date, and the
consolidated results of its operations and its consolidated cash flows for the
six-month period then ended (subject to normal year-end adjustments). All such
financial statements, including the related schedules and notes thereto, have
been prepared in accordance with GAAP applied consistently throughout the
periods involved (except as approved by the aforementioned firm of accountants
and disclosed therein). TWTC and its Subsidiaries do not have any material
Guarantee Obligations, contingent liabilities and liabilities for taxes, or any
long-term leases or unusual forward or long-term commitments, including any
interest rate or foreign currency swap or exchange transaction or other
obligation in respect of derivatives, that are not reflected in the most recent
financial statements referred to in this paragraph. During the period from June
30, 2000 to and including the date hereof there has been no Disposition by TWTC
or any of its Subsidiaries of any material part of its business or property.

<PAGE>   52
                                                                              47


                  4.2. No Change. Since June 30, 2000, there has been no
development or event that has had or could reasonably be expected to have a
Material Adverse Effect.

                  4.3. Existence; Compliance with Law. Each of TWTC and its
Subsidiaries (a) is duly organized, validly existing and in good standing under
the laws of the jurisdiction of its organization, (b) has the power and
authority under its constitutive documents, and the legal right, to own and
operate its property, to lease the property it operates as lessee and to conduct
the business in which it is currently engaged, (c) is duly qualified as a
foreign corporation, partnership or limited liability company, as the case may
be, and in good standing under the laws of each jurisdiction where its
ownership, lease or operation of property or the conduct of its business
requires such qualification and (d) is in compliance with all Requirements of
Law except to the extent that the failure to comply therewith could not, in the
aggregate, reasonably be expected to have a Material Adverse Effect.

                  4.4. Power; Authorization; Enforceable Obligations. Each Loan
Party has the power and authority under its constitutive documents, and the
legal right, to make, deliver and perform the Loan Documents to which it is a
party and, in the case of the Borrower, to obtain extensions of credit
hereunder. Each Loan Party has taken all necessary organizational action under
its constitutive documents to authorize the execution, delivery and performance
of the Loan Documents to which it is a party and, in the case of the Borrower,
to authorize the extensions of credit on the terms and conditions of this
Agreement. No consent or authorization of, filing with, notice to or other act
by or in respect of, any Governmental Authority or any other Person is required
in connection with the extensions of credit hereunder or with the execution,
delivery, performance, validity or enforceability of this Agreement or any of
the Loan Documents, except (i) consents, authorizations, filings and notices
described in Schedule 4.4, which consents, authorizations, filings and notices
have been obtained or made and are in full force and effect unless otherwise
indicated on Schedule 4.4 and (ii) the filings referred to in Section 4.19. Each
Loan Document has been duly executed and delivered on behalf of each Loan Party
party thereto. This Agreement constitutes, and each other Loan Document upon
execution will constitute, a legal, valid and binding obligation of each Loan
Party party thereto, enforceable against each such Loan Party in accordance with
its terms, except as enforceability may be limited by applicable bankruptcy,
insolvency, reorganization, moratorium or similar laws affecting the enforcement
of creditors' rights generally and by general equitable principles (whether
enforcement is sought by proceedings in equity or at law).

                  4.5. No Legal Bar. The execution, delivery and performance of
this Agreement and the other Loan Documents, the issuance of Letters of Credit,
the borrowings hereunder and the use of the proceeds thereof will not violate
any Requirement of Law or any Contractual Obligation of TWTC or any of its
Subsidiaries and will not result in, or require, the creation or imposition of
any Lien on any of their respective properties or revenues pursuant to any
Requirement of Law or any such Contractual Obligation (other than the Liens
permitted under Section 7.3). No Requirement of Law or Contractual Obligation
applicable to TWTC or any of its Subsidiaries could reasonably be expected to
have a Material Adverse Effect.

                                                                              48


                  4.6. Litigation. No litigation, investigation or proceeding of
or before any arbitrator or Governmental Authority is pending or, to the
knowledge of TWTC or the Borrower, threatened by or against TWTC or any of its
Subsidiaries or against any of their respective properties or revenues (a) with
respect to any of the Loan Documents or any of the transactions contemplated
hereby or thereby, or (b) that could reasonably be expected to have a Material
Adverse Effect.

                  4.7. No Default. Neither TWTC nor any of its Subsidiaries is
in default under or with respect to any of its Contractual Obligations in any
respect that could reasonably be expected to have a Material Adverse Effect. No
Default or Event of Default has occurred and is continuing.

                  4.8. Ownership of Property; Liens. Each of TWTC and its
Subsidiaries has title in fee simple to, or a valid leasehold interest in, all
its real property, and good title to, or a valid leasehold interest in, all its
other property, and none of such property is subject to any Lien except as
permitted by Section 7.3. TWTC has no Lien on the assets of any of its limited
partnership Subsidiaries pursuant to its limited partnership interests or
otherwise and any claim or interest that TWTC has in such assets is subordinated
and junior in right to that of the Lenders.

                  4.9. Intellectual Property. TWTC and each of its Subsidiaries
owns, or is licensed to use, all Intellectual Property necessary for the conduct
of its business as currently conducted. No material claim has been asserted and
is pending by any Person challenging or questioning the use of any Intellectual
Property or the validity or effectiveness of any Intellectual Property, nor does
TWTC or any of its Subsidiaries know of any valid basis for any such claim. The
use of Intellectual Property by TWTC and its Subsidiaries does not infringe on
the rights of any Person in any material respect.

                  4.10. Taxes. Each of TWTC and its Subsidiaries has filed or
caused to be filed all Federal, state and other material tax returns that are
required to be filed and has paid all taxes shown to be due and payable on said
returns or on any assessments made against it or any of its property and all
other taxes, fees or other charges imposed on it or any of its property by any
Governmental Authority (other than any the amount or validity of which are
currently being contested in good faith by appropriate proceedings and with
respect to which reserves in conformity with GAAP have been provided on the
books of TWTC or its Subsidiaries, as the case may be); no tax Lien has been
filed, and, to the knowledge of TWTC and the Borrower, no claim is being
asserted, with respect to any such tax, fee or other charge (except, in each
case, for taxes in respect of GST or its affiliates in an aggregate amount not
to exceed the amount held back from the purchase price paid by TWTC to GST and
its affiliates in connection with the Acquisition).

                  4.11. Federal Regulations. No part of the proceeds of any
Loans, and no other extensions of credit hereunder, will be used for "buying" or
"carrying" any "margin stock" within the respective meanings of each of the
quoted terms under Regulation U as now and from time to time hereafter in effect
or for any purpose that violates the provisions of the Regulations of the Board.
If requested by any Lender or the Administrative Agent, the Borrower will
furnish

<PAGE>   54
                                                                              49


to the Administrative Agent and each Lender a statement to the foregoing effect
in conformity with the requirements of FR Form G-3 or FR Form U-1, as
applicable, referred to in Regulation U.

                  4.12. Labor Matters. Except as, in the aggregate, could not
reasonably be expected to have a Material Adverse Effect: (a) there are no
strikes or other labor disputes against TWTC or any of its Subsidiaries pending
or, to the knowledge of TWTC or the Borrower, threatened; (b) hours worked by
and payment made to employees of TWTC and its Subsidiaries have not been in
violation of the Fair Labor Standards Act or any other applicable Requirement of
Law dealing with such matters; and (c) all payments due from TWTC or any of its
Subsidiaries on account of employee health and welfare insurance have been paid
or accrued as a liability on the books of TWTC or the relevant Subsidiary.

                  4.13. ERISA. Neither a Reportable Event with respect to a Plan
which, if terminated, would result in material liability nor an "accumulated
funding deficiency" (within the meaning of Section 412 of the Code or Section
302 of ERISA) has occurred during the five-year period prior to the date on
which this representation is made or deemed made with respect to any Plan, and
each Plan has complied in all material respects with the applicable provisions
of ERISA and the Code. No termination of a Single Employer Plan, other than a
standard termination pursuant to Section 4041(b) of ERISA, has occurred, and no
Lien in favor of the PBGC or a Plan has arisen, during such five-year period, in
either case with respect to which the Borrower has any outstanding liability.
The present value of all accrued benefits under each Single Employer Plan (based
on those assumptions used to fund such Plans) did not, as of the last annual
valuation date prior to the date on which this representation is made or deemed
made, exceed the value of the assets of such Plan allocable to such accrued
benefits by a material amount. Neither the Borrower nor any Commonly Controlled
Entity has had a complete or partial withdrawal from any Multiemployer Plan that
has resulted or could reasonably be expected to result in a material liability
under ERISA which has not been satisfied as of the date hereof, and neither the
Borrower nor any Commonly Controlled Entity would to the knowledge of the
Borrower become subject to any material liability under ERISA if the Borrower or
any such Commonly Controlled Entity were to withdraw completely from all
Multiemployer Plans as of the valuation date most closely preceding the date on
which this representation is made or deemed made. No such Multiemployer Plan is
in Reorganization or Insolvent.

                  4.14. Investment Company Act; Other Regulations. No Loan Party
is an "investment company", or a company "controlled" by an "investment
company", within the meaning of the Investment Company Act of 1940, as amended.
No Loan Party is subject to regulation under any Requirement of Law (other than
Regulation X of the Board) that limits its ability to incur Indebtedness.

                  4.15. Subsidiaries. Except as disclosed to the Administrative
Agent by the Borrower in writing from time to time after the Restatement
Effective Date, (a) Schedule 4.15 sets forth the name and jurisdiction of
incorporation of each Subsidiary and, as to each such Subsidiary, the percentage
of each class of Capital Stock owned by any Loan Party and (b) there are no
outstanding subscriptions, options, warrants, calls, rights or other agreements
or commitments (other than stock options granted to employees or directors and
directors'

<PAGE>   55
                                                                              50


qualifying shares) of any nature relating to any Capital Stock of the Borrower
or any Subsidiary of TWTC, except as created by the Loan Documents.

                  4.16. Use of Proceeds. The proceeds of the Term Loans shall be
used to finance the Acquisition and to pay related fees and expenses. The
remaining portion of the proceeds of the Term Loans, if any, and the proceeds of
the Revolving Loans, the Swingline Loans and the Letters of Credit shall be used
for general corporate purposes, working capital needs, including permitted
acquisitions and investments, and to fund the construction, expansion,
development or acquisition of properties or assets to be utilized directly or
indirectly, for the design, development, construction, installation,
integration, management or provision of any telecommunications business,
including voice, video, internet and data transmission products, services and
systems, fiber network construction and any business reasonably related to the
foregoing.

                  4.17. Environmental Matters. Except as, individually or in the
aggregate, could not reasonably be expected to have a Material Adverse Effect:

                  (a) the facilities and properties owned, leased or operated by
         TWTC or any of its Subsidiaries (the "Properties") do not contain any
         Materials of Environmental Concern in amounts or concentrations or
         under circumstances that constitute a violation of, or could reasonably
         be expected to give rise to liability under, any Environmental Law;

                  (b) neither TWTC nor any of its Subsidiaries has received any
         written notice of any violation, alleged violation, liability or
         potential liability regarding environmental matters or compliance with
         Environmental Laws with regard to any of the Properties or the business
         operated by TWTC or any of its Subsidiaries (the "Business"), nor does
         TWTC or the Borrower have knowledge that any such notice will be
         received or is being threatened;

                  (c) Materials of Environmental Concern have not been
         transported or disposed of from the Properties in violation of, or in a
         manner or to a location that could reasonably be expected to give rise
         to liability under, any Environmental Law, nor have any Materials of
         Environmental Concern been generated, treated, stored or disposed of
         at, on or under any of the Properties in violation of, or in a manner
         that could reasonably be expected to give rise to liability under, any
         applicable Environmental Law;

                  (d) no judicial proceeding or governmental or administrative
         action is pending or, to the knowledge of TWTC and the Borrower,
         threatened, under any Environmental Law to which TWTC or any Subsidiary
         is or will be named as a party with respect to the Properties or the
         Business, nor are there any consent decrees or other decrees, consent
         orders, administrative orders or other orders outstanding under any
         Environmental Law with respect to the Properties or the Business;

                  (e) there has been no release or threat of release of
         Materials of Environmental Concern at or from the Properties, or
         arising from or related to the operations of TWTC or any Subsidiary in
         connection with the Properties or otherwise in connection with the

<PAGE>   56
                                                                              51


         Business, in violation of or in amounts or in a manner that could give
         rise to liability under Environmental Laws; and

                  (f) the Properties and all operations at the Properties or
         otherwise in respect to the Business are in compliance, and have in the
         last five years been in compliance, with all applicable Environmental
         Laws.

                  4.18. Accuracy of Information, etc. No statement or
information contained in this Agreement, any other Loan Document, the
Confidential Information Memorandum or any other document, certificate or
statement furnished by or on behalf of any Loan Party to the Administrative
Agent or the Lenders, or any of them, for use in connection with the
transactions contemplated by this Agreement or the other Loan Documents,
contained as of the date such statement, information, document or certificate
was so furnished (or, in the case of the Confidential Information Memorandum, as
of the date of this Agreement), any untrue statement of a material fact or
omitted to state a material fact necessary to make the statements contained
herein or therein, when taken as a whole and in conjunction with TWTC's public
filings and disclosures, not misleading. The projections contained in the
materials referenced above are based upon good faith estimates and assumptions
believed by management of TWTC to be reasonable at the time made, it being
recognized by the Lenders that such financial information as it relates to
future events is not to be viewed as fact and that actual results during the
period or periods covered by such financial information may differ from the
projected results set forth therein by a material amount. To the best knowledge
of TWTC and the Borrower, as of the Restatement Effective Date, the
representations and warranties contained in the GST Asset Purchase Agreement are
true and correct in all material respects. There is no fact known to any Loan
Party that could reasonably be expected to have a Material Adverse Effect that
has not been expressly disclosed herein, in the other Loan Documents, in the
Confidential Information Memorandum or in any other documents, certificates and
statements furnished to the Administrative Agent and the Lenders for use in
connection with the transactions contemplated hereby and by the other Loan
Documents.

                  4.19. Security Documents. The Guarantee and Collateral
Agreement is effective to create or continue in favor of the Administrative
Agent, for the benefit of the Lenders, a legal, valid and enforceable security
interest in the Collateral described therein and proceeds thereof. In the case
of the pledged stock described in the Guarantee and Collateral Agreement, when
stock certificates representing such pledged stock are delivered to the
Administrative Agent, and in the case of the other Collateral described in the
Guarantee and Collateral Agreement, when financing statements and other filings
specified on Schedule 3 to the Guarantee and Collateral Agreement in appropriate
form are filed in the offices specified on Schedule 3 to the Guarantee and
Collateral Agreement, the Guarantee and Collateral Agreement shall constitute a
fully perfected Lien on, and security interest in, all right, title and interest
of the Loan Parties in such Collateral and the proceeds thereof to the extent
perfection may be accomplished by the filing of such financing statements and
other filings, as security for the Obligations (as defined in the Guarantee and
Collateral Agreement), in each case prior and superior in right to any other
Person (except, in the case of Collateral other than pledged stock, Liens
permitted by Section 7.3).

                                                                              52


                  4.20. Solvency. Except for any Shell Subsidiaries, each Loan
Party is, and after giving effect to the Acquisition and the incurrence of all
Indebtedness and obligations being incurred in connection herewith and therewith
will be and will continue to be, Solvent.

                  4.21. Certain Documents. The Borrower has delivered to the
Administrative Agent a complete and correct copy of the GST Asset Purchase
Agreement, including any amendments, supplements or modifications with respect
to any of the foregoing.

                        SECTION 5. CONDITIONS PRECEDENT

                  5.1. Conditions to the Initial Extension of Credit on or After
the Restatement Effective Date. The agreement of each Lender to make the initial
extension of credit requested to be made by it is subject to the satisfaction,
prior to or concurrently with the making of such extension of credit on the
Restatement Effective Date, of the following conditions precedent:

                  (a) Guarantee and Collateral Agreement. The Administrative
         Agent shall have received (i) the Guarantee and Collateral Agreement,
         executed and delivered by TWTC, the Borrower and each Subsidiary
         Guarantor and (ii) an Acknowledgment and Consent in the form attached
         to the Guarantee and Collateral Agreement, executed and delivered by
         each Issuer (as defined therein), if any, that is not a Loan Party.

                  (b) Additional Financing. The Administrative Agent shall have
         received evidence, in form, scope and substance reasonably satisfactory
         to the Administrative Agent and the Arranger, that TWTC shall have
         received cash proceeds of the Additional Financing in an aggregate
         amount of no less than $700,000,000, and that all such funds shall have
         been made available.

                  (c) Approvals. All material governmental and third party
         approvals (other than in connection with the consummation of the
         Acquisition) necessary or, in the reasonable discretion of the
         Administrative Agent, advisable in connection with the continuing
         operations of TWTC and its Subsidiaries and the transactions
         contemplated hereby shall have been obtained and be in full force and
         effect, and all applicable waiting periods shall have expired without
         any action being taken or threatened by any competent authority that
         would restrain, prevent or otherwise impose adverse conditions on the
         financing contemplated hereby.

                  (d) Closing Certificate. The Administrative Agent shall have
         received, with a counterpart for each Lender, a certificate of each
         Loan Party, dated the Restatement Effective Date, substantially in the
         form of Exhibit C, with appropriate insertions and attachments.

                  (e) Legal Opinions. The Administrative Agent shall have
         received the following executed legal opinions:

<PAGE>   58
                                                                              53

         case, proceeding or other action seeking issuance of a warrant of
         attachment, execution, distraint or similar process against all or any
         substantial part of its assets that results in the entry of an order
         for any such relief that shall not have been vacated, discharged, or
         stayed or bonded pending appeal within 60 days from the entry thereof;
         or (iv) TWTC or any of its Subsidiaries shall take any action in
         furtherance of, or indicating its consent to, approval of, or

         Lenders, likely to result in the termination of such Plan for purposes
         of Title IV of ERISA, (iv) any Single Employer Plan shall terminate for
         purposes of Title IV of ERISA, (v) the Borrower or any Commonly

         the sole judgment of the Required Lenders, reasonably be expected to
         have a Material Adverse Effect; or

         TWTC or any of its Subsidiaries involving in the aggregate a liability
         (to the extent (i) not paid by insurance or (ii) as to which no
         reasonable expectation of insurance coverage exists) of $10,000,000 or
         more (or, with respect to judgments related to reciprocal compensation

         been vacated, discharged, stayed or bonded pending appeal within 30
         days from the entry thereof; or

                  (i) any of the Security Documents shall cease, for any reason,

         any Loan Party shall so assert, or any Lien created by any of the
         Security Documents shall cease to be enforceable and of the same effect
         and priority purported to be created thereby; or

                  (j) the guarantee contained in Section 2 of the Guarantee and

         and effect or any Loan Party or any Affiliate of any Loan Party shall
         so assert; or

                  (k) the Time Warner Arrangements shall cease, for any reason,
         to be in full force and effect or any Loan Party or any Affiliate of
         any Loan Party shall so assert (other than any expiration of any of the
         Time Warner Arrangements in accordance with its terms that could not,
         individually or in the aggregate, reasonably be expected to have a
         Material Adverse Effect); or

                  (l) (i) the Permitted Investors shall cease to have the power

         on a fully diluted basis); (ii) the Permitted Investors shall cease to
         own of record and beneficially, directly or indirectly, securities of
         TWTC representing at least 30% (determined on a fully diluted basis) of

         terms are used in Sections 13(d) and 14(d) of the Securities Exchange
         Act of 1934, as amended (the "Exchange Act")), excluding the Permitted
         Investors, shall become, or obtain rights (whether by means or
         warrants, options or otherwise) to become, the "beneficial owner" (as
         defined in Rules 13(d)-3 and 13(d)-5 under the Exchange Act), directly
         or indirectly, of more than the percentage of the outstanding common
         stock of TWTC at the time owned and controlled by the Permitted

         outstanding Capital Stock of the Borrower free and clear of all Liens
         (except Liens created by the Guarantee and Collateral Agreement); or
         (vi) a Specified Change of Control shall occur; provided, that the
         merger of Time Warner, Inc. with AOL, Inc. is expressly permitted
         hereunder and shall not constitute an Event of Default under this
         Section 8(l);

then, and in any such event, (A) if such event is an Event of Default specified
in clause (i) or (ii) of paragraph (f) above with respect to the Borrower,
automatically the Commitments shall immediately terminate and the Loans
hereunder (with accrued interest thereon) and all other amounts owing under this
Agreement and the other Loan Documents (including all amounts of L/C
Obligations, whether or not the beneficiaries of the then outstanding Letters of
Credit shall have presented the documents required thereunder) shall immediately
become due and payable, and (B) if such event is any other Event of Default,
either or both of the following actions may be taken: (i) with the consent of
the Required Lenders, the Administrative Agent may, or upon the request of the
Required Lenders, the Administrative Agent shall, by notice to the Borrower

<PAGE>   80
                                                                              75


declare the Commitments to be terminated forthwith, whereupon the Commitments
shall immediately terminate; and (ii) with the consent of the Required Lenders,
the Administrative Agent may, or upon the request of the Required Lenders, the
Administrative Agent shall, by notice to the Borrower, declare the Loans
hereunder (with accrued interest thereon) and all other amounts owing under this
Agreement and the other Loan Documents (including all amounts of L/C
Obligations, whether or not the beneficiaries of the then outstanding Letters of
Credit shall have presented the documents required thereunder) to be due and
payable forthwith, whereupon the same shall immediately become due and payable.
With respect to all Letters of Credit with respect to which presentment for
honor shall not have occurred at the time of an acceleration pursuant to this
paragraph, the Borrower shall at such time deposit in a cash collateral account
opened by the Administrative Agent an amount equal to the aggregate then undrawn
and unexpired amount of such Letters of Credit. Amounts held in such cash
collateral account shall be applied by the Administrative Agent to the payment
of drafts drawn under such Letters of Credit, and the unused portion thereof
after all such Letters of Credit shall have expired or been fully drawn upon, if
any, shall be applied to repay other obligations of the Borrower hereunder and
under the other Loan Documents. After all such Letters of Credit shall have
expired or been fully drawn upon, all Reimbursement Obligations shall have been
satisfied and all other obligations of the Borrower hereunder and under the
other Loan Documents shall have been paid in full, the balance, if any, in such
cash collateral account shall be returned to the Borrower (or such other Person
as may be lawfully entitled thereto). Except as expressly provided above in this
Section, presentment, demand, protest and all other notices of any kind are
hereby expressly waived by the Borrower.

                             SECTION 9. THE AGENTS

                  9.1. Appointment. Each Lender hereby irrevocably designates
and appoints the Administrative Agent as the agent of such Lender under this
Agreement and the other Loan Documents, and each such Lender irrevocably
authorizes the Administrative Agent, in such capacity, to take such action on
its behalf under the provisions of this Agreement and the other Loan Documents
and to exercise such powers and perform such duties as are expressly delegated
to the Administrative Agent by the terms of this Agreement and the other Loan
Documents, together with such other powers as are reasonably incidental thereto.
Notwithstanding any provision to the contrary elsewhere in this Agreement, the
Administrative Agent shall not have any duties or responsibilities, except those
expressly set forth herein, or any fiduciary relationship with any Lender, and
no implied covenants, functions, responsibilities, duties, obligations or
liabilities shall be read into this Agreement or any other Loan Document or
otherwise exist against the Administrative Agent.

                  9.2. Delegation of Duties. The Administrative Agent may
execute any of its duties under this Agreement and the other Loan Documents by
or through agents or attorneys-in-fact and shall be entitled to advice of
counsel concerning all matters pertaining to such duties. The Administrative
Agent shall not be responsible for the negligence or misconduct of any agents or
attorneys in-fact selected by it with reasonable care.

<PAGE>   81
                                                                              76


                  9.3. Exculpatory Provisions. Neither any Agent nor any of
their respective officers, directors, employees, agents, attorneys-in-fact or
affiliates shall be (i) liable for any action lawfully taken or omitted to be
taken by it or such Person under or in connection with this Agreement or any
other Loan Document (except to the extent that any of the foregoing are found by
a final and nonappealable decision of a court of competent jurisdiction to have
resulted from its or such Person's own gross negligence or willful misconduct)
or (ii) responsible in any manner to any of the Lenders for any recitals,
statements, representations or warranties made by any Loan Party or any officer
thereof contained in this Agreement or any other Loan Document or in any
certificate, report, statement or other document referred to or provided for in,
or received by the Agents under or in connection with, this Agreement or any
other Loan Document or for the value, validity, effectiveness, genuineness,
enforceability or sufficiency of this Agreement or any other Loan Document or
for any failure of any Loan Party a party thereto to perform its obligations
hereunder or thereunder. The Agents shall not be under any obligation to any
Lender to ascertain or to inquire as to the observance or performance of any of
the agreements contained in, or conditions of, this Agreement or any other Loan
Document, or to inspect the properties, books or records of any Loan Party.

                  9.4. Reliance by Administrative Agent. The Administrative
Agent shall be entitled to rely, and shall be fully protected in relying, upon
any instrument, writing, resolution, notice, consent, certificate, affidavit,
letter, telecopy, telex or teletype message, statement, order or other document
or conversation believed by it to be genuine and correct and to have been
signed, sent or made by the proper Person or Persons and upon advice and
statements of legal counsel (including counsel to TWTC or the Borrower),
independent accountants and other experts selected by the Administrative Agent.
The Administrative Agent may deem and treat the payee of any Note as the owner
thereof for all purposes unless a written notice of assignment, negotiation or
transfer thereof shall have been filed with the Administrative Agent. The
Administrative Agent shall be fully justified in failing or refusing to take any
action under this Agreement or any other Loan Document unless it shall first
receive such advice or concurrence of the Required Lenders (or, if so specified
by this Agreement, all Lenders) as it deems appropriate or it shall first be
indemnified to its satisfaction by the Lenders against any and all liability and
expense that may be incurred by it by reason of taking or continuing to take any
such action. The Administrative Agent shall in all cases be fully protected in
acting, or in refraining from acting, under this Agreement and the other Loan
Documents in accordance with a request of the Required Lenders (or, if so
specified by this Agreement, all Lenders), and such request and any action taken
or failure to act pursuant thereto shall be binding upon all the Lenders and all
future holders of the Loans.

                  9.5. Notice of Default. The Administrative Agent shall not be
deemed to have knowledge or notice of the occurrence of any Default or Event of
Default hereunder unless the Administrative Agent has received notice from a
Lender, TWTC or the Borrower referring to this Agreement, describing such
Default or Event of Default and stating that such notice is a "notice of
default". In the event that the Administrative Agent receives such a notice, the
Administrative Agent shall give notice thereof to the Lenders. The
Administrative Agent shall take such action with respect to such Default or
Event of Default as shall be reasonably directed by the Required Lenders (or, if
so specified by this Agreement, all Lenders); provided that unless and until the
Administrative Agent shall have received such directions, the Administrative
Agent

<PAGE>   82
                                                                              77


may (but shall not be obligated to) take such action, or refrain from taking
such action, with respect to such Default or Event of Default as it shall deem
advisable in the best interests of the Lenders.

                  9.6. Non-Reliance on Agents and Other Lenders. Each Lender
expressly acknowledges that neither the Agents nor any of their respective
officers, directors, employees, agents, attorneys-in-fact or affiliates have
made any representations or warranties to it and that no act by any Agent
hereafter taken, including any review of the affairs of a Loan Party or any
affiliate of a Loan Party, shall be deemed to constitute any representation or
warranty by any Agent to any Lender. Each Lender represents to the Agents that
it has, independently and without reliance upon any Agent or any other Lender,
and based on such documents and information as it has deemed appropriate, made
its own appraisal of and investigation into the business, operations, property,
financial and other condition and creditworthiness of the Loan Parties and their
affiliates and made its own decision to make its Loans hereunder and enter into
this Agreement. Each Lender also represents that it will, independently and
without reliance upon any 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 analysis, appraisals and decisions in taking or not taking action
under this Agreement and the other Loan Documents, and to make such
investigation as it deems necessary to inform itself as to the business,
operations, property, financial and other condition and creditworthiness of the
Loan Parties and their affiliates. Except for notices, reports and other
documents expressly required to be furnished to the Lenders by the
Administrative Agent hereunder, the Administrative Agent shall not have any duty
or responsibility to provide any Lender with any credit or other information
concerning the business, operations, property, condition (financial or
otherwise), prospects or creditworthiness of any Loan Party or any affiliate of
a Loan Party that may come into the possession of the Administrative Agent or
any of its officers, directors, employees, agents, attorneys-in-fact or
affiliates.

                  9.7. Indemnification. The Lenders agree to indemnify each
Agent in its capacity as such (to the extent not reimbursed by TWTC or the
Borrower and without limiting the obligation of TWTC or the Borrower to do so),
ratably according to their respective Aggregate Exposure Percentages in effect
on the date on which indemnification is sought under this Section (or, if
indemnification is sought after the date upon which the Commitments shall have
terminated and the Loans shall have been paid in full, ratably in accordance
with such Aggregate Exposure Percentages immediately prior to such date), from
and against any and all liabilities, obligations, losses, damages, penalties,
actions, judgments, suits, costs, expenses or disbursements of any kind
whatsoever that may at any time (whether before or after the payment of the
Loans) be imposed on, incurred by or asserted against such Agent in any way
relating to or arising out of, the Commitments, this Agreement, any of the other
Loan Documents or any documents contemplated by or referred to herein or therein
or the transactions contemplated hereby or thereby or any action taken or
omitted by such Agent under or in connection with any of the foregoing; provided
that no Lender shall be liable for the payment of any portion of such
liabilities, obligations, losses, damages, penalties, actions, judgments, suits,
costs, expenses or disbursements that are found by a final and nonappealable
decision of a court of competent jurisdiction to have resulted from such Agent's
gross negligence or willful misconduct. The

<PAGE>   83
                                                                              78


agreements in this Section shall survive the payment of the Loans and all other
amounts payable hereunder.

                  9.8. Agent in Its Individual Capacity. Each Agent and its
affiliates may make loans to, accept deposits from and generally engage in any
kind of business with any Loan Party as though such Agent were not an Agent.
With respect to its Loans made or renewed by it and with respect to any Letter
of Credit issued or participated in by it, each Agent shall have the same rights
and powers under this Agreement and the other Loan Documents as any Lender and
may exercise the same as though it were not an Agent, and the terms "Lender" and
"Lenders" shall include each Agent in its individual capacity.

                  9.9. Successor Administrative Agent. The Administrative Agent
may resign as Administrative Agent upon 30 days' notice to the Lenders and the
Borrower. If the Administrative Agent shall resign as Administrative Agent under
this Agreement and the other Loan Documents, then the Required Lenders shall
appoint from among the Lenders a successor agent for the Lenders, which
successor agent shall (unless an Event of Default under Section 8(a) or Section
8(f) with respect to the Borrower shall have occurred and be continuing) be
subject to approval by the Borrower (which approval shall not be unreasonably
withheld or delayed), whereupon such successor agent shall succeed to the
rights, powers and duties of the Administrative Agent, and the term
"Administrative Agent" shall mean such successor agent effective upon such
appointment and approval, and the former Administrative Agent's rights, powers
and duties as Administrative Agent shall be terminated, without any other or
further act or deed on the part of such former Administrative Agent or any of
the parties to this Agreement or any holders of the Loans. If no successor agent
has accepted appointment as Administrative Agent by the date that is 30 days
following a retiring Administrative Agent's notice of resignation, the retiring
Administrative Agent's resignation shall nevertheless thereupon become effective
and the Lenders shall assume and perform all of the duties of the Administrative
Agent hereunder until such time, if any, as the Required Lenders appoint a
successor agent as provided for above. After any retiring Administrative Agent's
resignation as Administrative Agent, the provisions of this Section 9 shall
inure to its benefit as to any actions taken or omitted to be taken by it while
it was Administrative Agent under this Agreement and the other Loan Documents.

                  9.10. Documentation Agent and Co-Syndication Agents. Neither
the Documentation Agent nor the Co-Syndication Agents shall have any duties or
responsibilities hereunder in its capacity as such.

                           SECTION 10. MISCELLANEOUS

                  10.1. Amendments and Waivers. Neither this Agreement, any
other Loan Document, nor any terms hereof or thereof may be amended,
supplemented or modified except in accordance with the provisions of this
Section 10.1. The Required Lenders and each Loan Party party to the relevant
Loan Document may, or, with the written consent of the Required Lenders, the
Administrative Agent and each Loan Party party to the relevant Loan Document
may, from time to time, (a) enter into written amendments, supplements or
modifications hereto and to the other Loan Documents for the purpose of adding
any provisions to this Agreement or

<PAGE>   84
                                                                              79


the other Loan Documents or changing in any manner the rights of the Lenders or
of the Loan Parties hereunder or thereunder or (b) waive, on such terms and
conditions as the Required Lenders or the Administrative Agent (with the written
consent of the Required Lenders), as the case may be, may specify in such
instrument, any of the requirements of this Agreement or the other Loan
Documents or any Default or Event of Default and its consequences, including,
without limitation, the termination of the Commitments and the Loans being due
and payable; provided, however, that no such waiver and no such amendment,
supplement or modification shall (i) forgive the principal amount or extend the
final scheduled date of maturity of any Loan, extend the scheduled date of any
reduction of the Revolving Commitments provided in Section 2.3(c), extend the
date for any scheduled amortization payment in respect of any Term Loan, reduce
the stated rate of any interest or fee payable hereunder (except that any
amendment or modification of defined terms used in the financial covenants in
this Agreement shall not constitute a reduction in the rate of interest or fees
for purposes of this clause (i)) or extend the scheduled date of any payment
thereof, or increase the amount or extend the expiration date of any Lender's
Commitment, in each case without the written consent of each Lender directly
affected thereby; (ii) eliminate or reduce the voting rights of any Lender under
this Section 10.1 without the written consent of such Lender; (iii) reduce any
percentage specified in the definition of Required Lenders, consent to the
assignment or transfer by the Borrower of any of its rights and obligations
under this Agreement and the other Loan Documents, release all or substantially
all of the Collateral or release all or substantially all of the Subsidiary
Guarantors from their obligations under the Guarantee and Collateral Agreement,
in each case without the written consent of all Lenders; (iv) amend, modify or
waive any provision of Section 2.15(a), (b) or (c) without the written consent
of each Lender adversely affected thereby; (v) reduce the percentage specified
in the definition of Majority Facility Lenders with respect to any Facility
without the written consent of all Lenders under such Facility; (vi) amend,
modify or waive any provision of Section 9 without the written consent of the
Administrative Agent; (vii) amend, modify or waive any provision of Section 2.4
or 2.5 without the written consent of the Swingline Lender; or (viii) amend,
modify or waive any provision of Section 3 without the written consent of the
Issuing Lender. Any such waiver and any such amendment, supplement or
modification shall apply equally to each of the Lenders and shall be binding
upon the Loan Parties, the Lenders, the Administrative Agent and all future
holders of the Loans. In the case of any waiver, the Loan Parties, the Lenders
and the Administrative Agent shall be restored to their former position and
rights hereunder and under the other Loan Documents, and any Default or Event of
Default waived shall be deemed to be cured and not continuing; but no such
waiver shall extend to any subsequent or other Default or Event of Default, or
impair any right consequent thereon.

                  For the avoidance of doubt, this Agreement may be amended (or
amended and restated) with the written consent of the Required Lenders, the
Administrative Agent and the Borrower (a) to add one or more additional credit
facilities to this Agreement and to permit the extensions of credit from time to
time outstanding thereunder and the accrued interest and fees in respect thereof
(collectively, the "Additional Extensions of Credit") to share ratably in the
benefits of this Agreement and the other Loan Documents with the Term Loans and
the Revolving Extensions of Credit and the accrued interest and fees in respect
thereof and (b) to include appropriately the Lenders holding such credit
facilities in any determination of the Required Lenders and the Majority
Facility Lenders.

provided that any notice, request or demand to or upon the Administrative Agent
or the Lenders shall not be effective until received.

                  10.3. No Waiver; Cumulative Remedies. No failure to exercise
and no delay in exercising, on the part of the Administrative Agent or any
Lender, any right, remedy, power or privilege hereunder or under the other Loan
Documents shall operate as a waiver thereof; nor shall any single or partial
exercise of any right, remedy, power or privilege hereunder preclude any other
or further exercise thereof or the exercise of any other right, remedy, power or
privilege. The rights, remedies, powers and privileges herein provided are
cumulative and not exclusive of any rights, remedies, powers and privileges
provided by law.

                  10.4. Survival of Representations and Warranties. All
representations and warranties made hereunder, in the other Loan Documents and
in any document, certificate or statement delivered pursuant hereto or in
connection herewith shall survive the execution and delivery of this Agreement
and the making of the Loans and other extensions of credit hereunder.

                  10.5. Payment of Expenses and Taxes. Each of TWTC and the
Borrower agrees (a) to pay or reimburse the Administrative Agent and the
Arrangers for all their reasonable out-of-pocket costs and expenses incurred in
connection with the development, preparation and execution of, and any
amendment, supplement or modification to, this Agreement and the other Loan
Documents and any other documents prepared in connection herewith or therewith,
and the consummation and administration of the transactions contemplated hereby
and thereby, including the reasonable fees and disbursements of counsel to the
Administrative Agent and filing and recording fees and expenses, with statements
with respect to the foregoing to be submitted to the Borrower prior to the
Restatement Effective Date (in the case of amounts to be paid on the Restatement
Effective Date) and from time to time thereafter on a quarterly basis or such
other periodic basis as the Administrative Agent shall deem appropriate, (b) to
pay or reimburse each Lender and the Administrative Agent for all its costs and
expenses incurred in connection with the enforcement or preservation of any
rights under this Agreement, the other Loan Documents and any such other
documents, including the fees and disbursements of counsel to each Lender and of
counsel to the Administrative Agent and the Arrangers, (c) to pay, indemnify,
and hold each Lender and the Administrative Agent harmless from, any and all
recording and filing fees and any and all liabilities with respect to, or
resulting from any delay in paying, stamp, excise and other taxes, if any, that
may be payable or determined to be payable in connection with the execution and
delivery of, or consummation or administration of any of the transactions
contemplated by, or any amendment, supplement or modification of, or any waiver
or consent under or in respect of, this Agreement, the other Loan Documents and
any such other documents, and (d) to pay, indemnify, and hold each Lender, the
Administrative Agent and the Arrangers and their respective officers, directors,
employees, affiliates, agents and controlling persons (each, an "Indemnitee")
harmless from and against any and all other liabilities, obligations, losses,
damages, penalties, actions, judgments, suits, costs, expenses or disbursements
of any kind or nature whatsoever with respect to the execution, delivery,
enforcement, performance and administration of this Agreement, the other Loan
Documents and

<PAGE>   87
                                                                              82


any such other documents, including any of the foregoing relating to the use of
proceeds of the Loans or the violation of, noncompliance with or liability
under, any Environmental Law applicable to the operations of TWTC or any of its
Subsidiaries or any of the Properties and the reasonable fees and expenses of
legal counsel in connection with claims, actions or proceedings by any
Indemnitee against any Loan Party under any Loan Document (all the foregoing in
this clause (d), collectively, the "Indemnified Liabilities"), provided, that
neither TWTC nor the Borrower shall have any obligation hereunder to any
Indemnitee with respect to Indemnified Liabilities to the extent such
Indemnified Liabilities are found by a final and nonappealable decision of a
court of competent jurisdiction to have resulted from the gross negligence or
willful misconduct of such Indemnitee. It is understood and agreed that, to the
extent not precluded by a conflict of interest, each Indemnitee shall endeavor
to work cooperatively with a view to minimizing the legal and other expenses
associated with any defense and any potential settlement or judgment. Without
limiting the foregoing, and to the extent permitted by applicable law, TWTC
agrees not to assert and to cause its Subsidiaries not to assert, and hereby
waives and agrees to cause its Subsidiaries to waive, all rights for
contribution or any other rights of recovery with respect to all claims,
demands, penalties, fines, liabilities, settlements, damages, costs and expenses
of whatever kind or nature, under or related to Environmental Laws, that any of
them might have by statute or otherwise against any Indemnitee. All amounts due
under this Section 10.5 shall be payable not later than 10 days after written
demand therefor. Statements payable by TWTC or the Borrower pursuant to this
Section 10.5 shall be submitted to the address of the Borrower set forth in
Section 10.2, or to such other Person or address as may be hereafter designated
by the Borrower in a written notice to the Administrative Agent. The agreements
in this Section 10.5 shall survive repayment of the Loans and all other amounts
payable hereunder.

                  10.6. Successors and Assigns; Participations and Assignments.
(a) This Agreement shall be binding upon and inure to the benefit of TWTC, the
Borrower, the Lenders, the Administrative Agent, all future holders of the Loans
and their respective successors and assigns, except that the Borrower may not
assign or transfer any of its rights or obligations under this Agreement without
the prior written consent of each Lender.

                  (b) Any Lender other than any Conduit Lender may, without the
consent of the Borrower, in accordance with applicable law, at any time sell to
one or more banks, financial institutions or other entities (each, a
"Participant") participating interests in any Loan owing to such Lender, any
Commitment of such Lender or any other interest of such Lender hereunder and
under the other Loan Documents. In the event of any such sale by a Lender of a
participating interest to a Participant, such Lender's obligations under this
Agreement to the other parties to this Agreement shall remain unchanged, such
Lender shall remain solely responsible for the performance thereof, such Lender
shall remain the holder of any such Loan for all purposes under this Agreement
and the other Loan Documents, and the Borrower and the Administrative Agent
shall continue to deal solely and directly with such Lender in connection with
such Lender's rights and obligations under this Agreement and the other Loan
Documents. In no event shall any Participant under any such participation have
any right to approve any amendment or waiver of any provision of any Loan
Document, or any consent to any departure by any Loan Party therefrom, except to
the extent that such amendment, waiver or consent would reduce the principal of,
or interest on, the Loans or any fees payable hereunder, or postpone the

<PAGE>   88
                                                                              83


date of the final maturity of the Loans, in each case to the extent subject to
such participation. The Borrower agrees that if amounts outstanding under this
Agreement and the Loans are due or unpaid, or shall have been declared or shall
have become due and payable upon the occurrence of an Event of Default, each
Participant shall, to the maximum extent permitted by applicable law, be deemed
to have the right of setoff in respect of its participating interest in amounts
owing under this Agreement to the same extent as if the amount of its
participating interest were owing directly to it as a Lender under this
Agreement, provided that, in purchasing such participating interest, such
Participant shall be deemed to have agreed to share with the Lenders the
proceeds thereof as provided in Section 10.7(a) as fully as if it were a Lender
hereunder. The Borrower also agrees that each Participant shall be entitled to
the benefits of Sections 2.16, 2.17 and 2.18 with respect to its participation
in the Commitments and the Loans outstanding from time to time as if it was a
Lender; provided that, in the case of Section 2.19, such Participant shall have
complied with the requirements of said Section and provided, further, that no
Participant shall be entitled to receive any greater amount pursuant to any such
Section than the transferor Lender would have been entitled to receive in
respect of the amount of the participation transferred by such transferor Lender
to such Participant had no such transfer occurred.

                  (c) Any Lender other than any Conduit Lender (an "Assignor")
may, in accordance with applicable law, at any time and from time to time assign
to any Lender, any affiliate of any Lender or any Approved Fund or, with the
consent of the Borrower and the Administrative Agent (which, in each case, shall
not be unreasonably withheld or delayed), to an additional bank, financial
institution or other entity (an "Assignee") all or any part of its rights and
obligations under this Agreement and the other Loan Documents pursuant to an
Assignment and Acceptance, executed by such Assignee, such Assignor and any
other Person whose consent is required pursuant to this paragraph, and delivered
to the Administrative Agent for its acceptance and recording in the Register;
provided that, unless otherwise agreed by the Borrower and the Administrative
Agent, no such assignment to an Assignee (other than any Lender or any affiliate
of any Lender or any Approved Fund) shall be in an aggregate principal amount of
less than $5,000,000 (or, in the case of the Tranche B Term Facility,
$1,000,000), in each case except in the case of an assignment of all of a
Lender's interests under this Agreement. For purposes of the proviso contained
in the preceding sentence, the amount described therein shall be aggregated in
respect of each Lender and its related Approved Funds, if any. Any such
assignment need not be ratable as among the Facilities. Upon such execution,
delivery, acceptance and recording, from and after the effective date determined
pursuant to such Assignment and Acceptance, (x) the Assignee thereunder shall be
a party hereto and, to the extent provided in such Assignment and Acceptance,
have the rights and obligations of a Lender hereunder with a Commitment and/or
Loans as set forth therein, and (y) the Assignor thereunder shall, to the extent
provided in such Assignment and Acceptance, be released from its obligations
under this Agreement (and, in the case of an Assignment and Acceptance covering
all of an Assignor's rights and obligations under this Agreement, such Assignor
shall cease to be a party hereto) except with respect to its obligations under
Section 10.15. Notwithstanding any provision of this Section 10.6, the consent
of the Borrower shall not be required for any assignment that occurs when an
Event of Default pursuant to Section 8(a) or Section 8(f) shall have occurred
and be continuing with respect to the Borrower. Notwithstanding the foregoing,
any Conduit Lender may assign at any time to its designating Lender hereunder
without the consent of the Borrower or the Administrative Agent any or all of
the Loans it may have funded

<PAGE>   89
                                                                              84


hereunder and pursuant to its designation agreement and without regard to the
limitations set forth in the first sentence of this Section 10.6(c).

                  (d) The Administrative Agent shall, on behalf of the Borrower,
maintain at its address referred to in Section 10.2 a copy of each Assignment
and Acceptance delivered to it and a register (the "Register") for the
recordation of the names and addresses of the Lenders and the Commitment of, and
the principal amount of the Loans owing to, each Lender from time to time. The
entries in the Register shall be conclusive, in the absence of manifest error,
and the Borrower, each other Loan Party, the Administrative Agent and the
Lenders shall treat each Person whose name is recorded in the Register as the
owner of the Loans and any Notes evidencing the Loans recorded therein for all
purposes of this Agreement. Any assignment of any Loan, whether or not evidenced
by a Note, shall be effective only upon appropriate entries with respect thereto
being made in the Register (and each Note shall expressly so provide). Any
assignment or transfer of all or part of a Loan evidenced by a Note shall be
registered on the Register only upon surrender for registration of assignment or
transfer of the Note evidencing such Loan, accompanied by a duly executed
Assignment and Acceptance, and thereupon one or more new Notes shall be issued
to the designated Assignee.

                  (e) Upon its receipt of an Assignment and Acceptance executed
by an Assignor, an Assignee and any other Person whose consent is required by
Section 10.6(c), together with payment to the Administrative Agent of a
registration and processing fee of $3,500, the Administrative Agent shall (i)
promptly accept such Assignment and Acceptance and (ii) record the information
contained therein in the Register on the effective date determined pursuant
thereto.

                  (f) For avoidance of doubt, the parties to this Agreement
acknowledge that the provisions of this Section 10.6 concerning assignments of
Loans and Notes relate only to absolute assignments and that such provisions do
not prohibit assignments creating security interests, including any pledge or
assignment by a Lender of any Loan or Note to any Federal Reserve Bank in
accordance with applicable law.

                  (g) The Borrower, upon receipt of written notice from the
relevant Lender, agrees to issue Notes to any Lender requiring Notes to
facilitate transactions of the type described in paragraph (f) above.

                  (h) Each of TWTC, the Borrower, each Lender and the
Administrative Agent hereby confirms that it will not institute against a
Conduit Lender or join any other Person in instituting against a Conduit Lender
any bankruptcy, reorganization, arrangement, insolvency or liquidation
proceeding under any state bankruptcy or similar law, for one year and one day
after the payment in full of the latest maturing commercial paper note issued by
such Conduit Lender; provided, however, that each Lender designating any Conduit
Lender hereby agrees to indemnify, save and hold harmless each other party
hereto for any loss, cost, damage or expense arising out of its inability to
institute such a proceeding against such Conduit Lender during such period of
forbearance.

                                                                              85


                  10.7. Adjustments; Set-off. (a) Except to the extent that this
Agreement expressly provides for payments to be allocated to a particular Lender
or to the Lenders under a particular Facility, if any Lender (a "Benefitted
Lender") shall receive any payment of all or part of the Obligations owing to
it, or receive any collateral in respect thereof (whether voluntarily or
involuntarily, by set-off, pursuant to events or proceedings of the nature
referred to in Section 8(f), or otherwise), in a greater proportion than any
such payment to or collateral received by any other Lender, if any, in respect
of the Obligations owing to such other Lender, such Benefitted Lender shall
purchase for cash from the other Lenders a participating interest in such
portion of the Obligations owing to each such other Lender, or shall provide
such other Lenders with the benefits of any such collateral, as shall be
necessary to cause such Benefitted Lender to share the excess payment or
benefits of such collateral ratably with each of the Lenders; provided, however,
that if all or any portion of such excess payment or benefits is thereafter
recovered from such Benefitted Lender, such purchase shall be rescinded, and the
purchase price and benefits returned, to the extent of such recovery, but
without interest.

                  (b) In addition to any rights and remedies of the Lenders
provided by law, each Lender shall have the right, without prior notice to TWTC
or the Borrower, any such notice being expressly waived by TWTC and the Borrower
to the extent permitted by applicable law, upon any amount becoming due and
payable by TWTC or the Borrower hereunder, subject to applicable grace periods
(whether at the stated maturity, by acceleration or otherwise), to set off and
appropriate and apply against such amount any and all deposits (general or
special, time or demand, provisional or final), in any currency, and any other
credits, indebtedness or claims, in any currency, in each case whether direct or
indirect, absolute or contingent, matured or unmatured, at any time held or
owing by such Lender or any branch or agency thereof to or for the credit or the
account of TWTC or the Borrower, as the case may be. Each Lender agrees promptly
to notify the Borrower and the Administrative Agent after any such setoff and
application made by such Lender, provided that the failure to give such notice
shall not affect the validity of such setoff and application.

                  10.8. Counterparts. This Agreement may be executed by one or
more of the parties to this Agreement on any number of separate counterparts,
and all of said counterparts taken together shall be deemed to constitute one
and the same instrument. Delivery of an executed signature page of this
Agreement by facsimile transmission shall be effective as delivery of a manually
executed counterpart hereof. A set of the copies of this Agreement signed by all
the parties shall be lodged with the Borrower and the Administrative Agent.

                  10.9. Severability. Any provision of this Agreement that is
prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction,
be ineffective to the extent of such prohibition or unenforceability without
invalidating the remaining provisions hereof, and any such prohibition or
unenforceability in any jurisdiction shall not invalidate or render
unenforceable such provision in any other jurisdiction.

                  10.10. Integration. This Agreement and the other Loan
Documents represent the entire agreement of TWTC, the Borrower, the
Administrative Agent and the Lenders with respect to the subject matter hereof
and thereof, and there are no promises, undertakings,

<PAGE>   91
                                                                              86


representations or warranties by the Administrative Agent or any Lender relative
to subject matter hereof not expressly set forth or referred to herein or in the
other Loan Documents.

                  10.11. GOVERNING LAW. THIS AGREEMENT AND THE RIGHTS AND
OBLIGATIONS OF THE PARTIES UNDER THIS AGREEMENT SHALL BE GOVERNED BY, AND
CONSTRUED AND INTERPRETED IN ACCORDANCE WITH, THE LAW OF THE STATE OF NEW YORK.

                  10.12. Submission To Jurisdiction; Waivers. Each of TWTC and
the Borrower hereby irrevocably and unconditionally:

                  (a) submits for itself and its property in any legal action or
         proceeding relating to this Agreement and the other Loan Documents to
         which it is a party, or for recognition and enforcement of any judgment
         in respect thereof, to the non-exclusive general jurisdiction of the
         courts of the State of New York, the courts of the United States for
         the Southern District of New York, and appellate courts from any
         thereof;

                  (b) consents that any such action or proceeding may be brought
         in such courts and waives any objection that it may now or hereafter
         have to the venue of any such action or proceeding in any such court or
         that such action or proceeding was brought in an inconvenient court and
         agrees not to plead or claim the same;

                  (c) agrees that service of process in any such action or
         proceeding may be effected by mailing a copy thereof by registered or
         certified mail (or any substantially similar form of mail), postage
         prepaid, to TWTC or the Borrower, as the case may be at its address set
         forth in Section 10.2 or at such other address of which the
         Administrative Agent shall have been notified pursuant thereto;

                  (d) agrees that nothing herein shall affect the right to
         effect service of process in any other manner permitted by law or shall
         limit the right to sue in any other jurisdiction; and

                  (e) waives, to the maximum extent not prohibited by law, any
         right it may have to claim or recover in any legal action or proceeding
         referred to in this Section any special, exemplary, punitive or
         consequential damages.

                  10.13. Acknowledgments. Each of TWTC and the Borrower hereby
acknowledges that:

                  (a) it has been advised by counsel in the negotiation,
         execution and delivery of this Agreement and the other Loan Documents;

                  (b) neither the Administrative Agent nor any Lender has any
         fiduciary relationship with or duty to TWTC or the Borrower arising out
         of or in connection with this Agreement or any of the other Loan
         Documents, and the relationship between Administrative Agent and
         Lenders, on one hand, and TWTC and the Borrower, on the other hand, in
         connection herewith or therewith is solely that of debtor and creditor;
         and

<PAGE>   92
                                                                              87


                  (c) no joint venture is created hereby or by the other Loan
         Documents or otherwise exists by virtue of the transactions
         contemplated hereby among the Lenders or among TWTC, the Borrower and
         the Lenders.

                  10.14. Releases of Guarantees and Liens. (a) Notwithstanding
anything to the contrary contained herein or in any other Loan Document, the
Administrative Agent is hereby irrevocably authorized by each Lender (without
requirement of notice to or consent of any Lender except as expressly required
by Section 10.1) to take any action requested by the Borrower having the effect
of releasing any Collateral or guarantee obligations (i) to the extent necessary
to permit consummation of any transaction not prohibited by any Loan Document or
that has been consented to in accordance with Section 10.1 or (ii) under the
circumstances described in paragraph (b) below.

                  (b) At such time as the Loans, the Reimbursement Obligations
and the other obligations under the Loan Documents (other than obligations under
or in respect of Hedge Agreements) shall have been paid in full, the Commitments
have been terminated and no Letters of Credit shall be outstanding, the
Collateral shall be released from the Liens created by the Security Documents,
and the Security Documents and all obligations (other than those expressly
stated to survive such termination) of the Administrative Agent and each Loan
Party under the Security Documents shall terminate, all without delivery of any
instrument or performance of any act by any Person.

                  10.15. Confidentiality. Each of the Administrative Agent and
each Lender agrees to keep confidential all non-public information (including
oral information) provided to it by any Loan Party pursuant to this Agreement
that is designated by such Loan Party as confidential; provided that nothing
herein shall prevent the Administrative Agent or any Lender from disclosing any
such information (a) to the Administrative Agent, any other Lender, any
affiliate of any Lender or any Approved Fund (provided that such Affiliate or
Approved Fund expressly agrees to comply with the provisions of this Section),
(b) to any actual or prospective Transferee or Hedge Agreement counterparty that
expressly agrees to comply with the provisions of this Section, (c) to its
employees, directors, agents, attorneys, accountants and other professional
advisors or those of any of its affiliates, (d) upon the request or demand of
any Governmental Authority, (e) in response to any order of any court or other
Governmental Authority or as may otherwise be required pursuant to any
Requirement of Law, (f) if requested or required to do so in connection with any
litigation or similar proceeding, (g) that has been publicly disclosed or
otherwise disclosed to such Person on a non-confidential basis, (h) to the
National Association of Insurance Commissioners or any similar organization or
any nationally recognized rating agency that requires access to information
about a Lender's investment portfolio in connection with ratings issued with
respect to such Lender, (i) in connection with the exercise of any remedy
hereunder or under any other Loan Document or (j) to any direct or indirect
contractual counterparty in swap agreements or such contractual counterparty's
professional advisor (so long as such contractual counterparty or professional
advisor to such contractual counterparty expressly agrees to be bound by the
provisions of this Section 10.15); provided, further, that with respect to
disclosures pursuant to clauses (d), (e) and (f) of this Section, unless
prohibited by applicable law or court order, each Lender and the Administrative
Agent shall attempt to notify TWTC of any request by any governmental agency or
representative thereof or other Person

<PAGE>   93
                                                                              88


(other than any such request in connection with an examination of the financial
condition of such Lender by such governmental agency) for disclosure of any
material confidential information after receipt of such request, and if
reasonably practicable and permissible, before disclosure of such information.

                  10.16. WAIVERS OF JURY TRIAL. TWTC, THE BORROWER, THE
ADMINISTRATIVE AGENT AND THE LENDERS HEREBY IRREVOCABLY AND UNCONDITIONALLY
WAIVE TRIAL BY JURY IN ANY LEGAL ACTION OR PROCEEDING RELATING TO THIS AGREEMENT
