letter of credit shall have an expiration date (including all rights of a
Borrower or the beneficiary to require renewals, but excluding automatic renewal
provisions if such Issuing Bank can, in its discretion, refuse to renew and
thereby cause the expiration date to occur no later than 7 Business Days prior

liability to pay such amount and shall be unconditionally obligated to such
Issuing Bank to the extent provided in this Section 2.2.

Borrower pursuant to this sentence. Each Borrower hereby unconditionally agrees
to pay and reimburse the Agent for the account of the Issuing Bank that issued a
Letter of Credit at the request of such Borrower for the amount of each demand
for payment under such Letter of Credit that is in substantial compliance with
the provisions of such Letter of Credit at or prior to the date on which payment
is to be made by such Issuing Bank to the beneficiary thereunder (or on the next
Business Day, if same day payment is required by the terms of such Letter of
Credit pursuant to a request of such Borrower and if the notice to such Borrower
from such Issuing Bank in respect of such demand contemplated by the first
sentence of this Section 2.2(c) is not given prior to 9:00 a.m. (New York City
time) on such date), without presentment, demand, protest or other formalities
of any kind, in each case together with interest thereon at a rate per annum
equal to the Base Rate plus the Applicable Margin in effect from time to time
for such Borrower as to Base Rate Advances, for the period from the date of such
demand until the date of such reimbursement. Each Borrower's obligations to
reimburse each Issuing Bank as provided herein shall be absolute,


                                      -21-


unconditional and irrevocable under all circumstances whatsoever, including the
following circumstances: (i) any lack of validity of this Agreement, the other
Credit Documents or the other documents to be delivered under this Agreement;
(ii) the existence of any claim, set-off, defense or other right that a Borrower
may have at any time against the Agent, any Bank, any Issuing Bank or any other
Person, whether in connection with the transactions contemplated by this
Agreement or any unrelated transaction; (iii) any action or inaction taken or
suffered by any Issuing Bank under a Letter of Credit if taken in good faith and
in conformity with applicable law; (iv) the payment by any Issuing Bank under a
Letter of Credit against presentation of a demand, statement or other document
which in the sole discretion of such Issuing Bank substantially complies with
the terms of such Letter of Credit, including any demand, statement or other
document which is forged, fraudulent, invalid or inaccurate in any respect; (v)
any exchange, release or non-perfection of any collateral for, or any release or
amendment or waiver of or consent to departure from any guarantee of, all or any
of the Obligations in respect of any Letter of Credit; and (vi) any
determination of invalidity or unenforceability with respect to any Letter of
Credit after payment by an Issuing Bank thereunder.

      (d) Payments by Banks to Issuing Banks. To the extent that a Borrower
fails to make any payment to an Issuing Bank that such Borrower is required to
make pursuant to Section 2.2(c), each Bank (other than such Issuing Bank) shall
pay to the Agent, for the account of such Issuing Bank in Dollars and in
immediately available funds, the amount of such Bank's LC Participation
Percentage of any payment under a Letter of Credit upon notice by such Issuing
Bank (through the Agent) to such Bank requesting such payment and specifying
such amount. Each such Bank's obligation to make such payment to the Agent for
the account of such Issuing Bank under this Section 2.2(d), and such Issuing
Bank's right to receive the same, shall be absolute and unconditional and shall
not be affected by any circumstance whatsoever other than the gross negligence
or willful misconduct of such Issuing Bank in making payment under such Letter
of Credit, including the failure of any other Bank to make its payment under
this Section 2.2(d), the financial condition of a Borrower (or any other
Person), the existence of any Default or Event of Default, the incorrectness of
any representation or warranty, the existence of any claim, set-off, defense or
other right, any amendment, extension or other modification of any Letter of
Credit or the reduction or termination of the Letter of Credit Commitments or
the Revolving Credit Commitments. If any Bank shall default in its obligation to
make any such payment to the Agent for the account of an Issuing Bank, for so
long as such default shall continue the Agent may, at the request of such
Issuing Bank, withhold from any payments received by the Agent under this
Agreement for the account of such Bank the amount so in default and, to the
extent so withheld, pay the same to such Issuing Bank for application to such
defaulted obligation.

      (e) Participations in Reimbursement Obligations. Upon the making of each
payment by a Bank to an Issuing Bank pursuant to Section 2.2(d) in respect of
any Letter of Credit, such Bank shall, automatically and without any further
action on the part of the Agent, any Issuing Bank or such Bank, acquire (i) a
funded participation in an amount equal to such payment in the Reimbursement
Obligation owing to such Issuing Bank by the applicable Borrower hereunder and
under the Letter of Credit Documents relating to such Letter of Credit and (ii)
a participation in a percentage equal to such Bank's LC Participation Percentage
in any interest or other amounts payable by the applicable Borrower hereunder
and under such Letter of Credit Documents in respect of such Reimbursement
Obligation (other than the Fronting Fee contemplated by Section 2.11(b)(i)).
Upon receipt by any Issuing Bank from or for the account of a Borrower of any
payment in respect of any Reimbursement Obligation or any such interest or other
amount (including by way of setoff or application of proceeds of any collateral
security or the withdrawal and application of funds from an LC Cash Collateral
Account in respect of such Borrower), such Issuing Bank shall promptly pay to
the Agent, for the account of each Bank entitled thereto, such Bank's LC
Participation Percentage of such payment, each such payment by such Issuing Bank
to be made in the same currency and funds in which received by such Issuing
Bank. In the event any payment received by any Issuing Bank and so paid to the
Banks hereunder is rescinded or must


                                      -22-


otherwise be returned by such Issuing Bank, each Bank shall, upon the request of
such Issuing Bank (through the Agent), repay to such Issuing Bank (through the
Agent) the portion of such payment paid to such Bank.

      (f) Information Provided by Issuing Banks to Banks. Promptly after the
issuance of or amendment to any Letter of Credit, the Issuing Bank that issued
such Letter of Credit will notify the Agent and the applicable Borrower in
writing of such issuance or amendment and such notice shall be accompanied by a
copy of such issued or amended Letter of Credit. Upon receipt of such notice,
the Agent shall notify each Bank of such issuance or amendment and, if requested
by a Bank, the Agent shall provide such Bank with copies of such issued or
amended Letter of Credit and any Letter of Credit Documents related thereto
delivered to the Agent.

      (g) Conditions Precedent to Issuance, Modification and Addition. The
obligation of any Issuing Bank to issue a Letter of Credit shall be subject to
satisfaction of each of the conditions precedent set forth in Section 3.2, and
shall further be subject to the conditions precedent that (i) such Letter of
Credit shall be in such form and contain such terms as shall be reasonably
satisfactory to such Issuing Bank consistent with its then current practices and
procedures of general applicability with respect to letters of credit of the
same type and (ii) the applicable Borrower shall have executed and delivered
such applications, agreements and other instruments relating to such Letter of
Credit as such Issuing Bank shall have reasonably requested consistent with its
then current practices and procedures of general applicability with respect to
letters of credit of the same type; provided that in the event of any conflict
between any such application, agreement or other instrument and the provisions
of this Agreement, the provisions of this Agreement shall control. The
obligation of any Issuing Bank to make any amendment, modification or supplement
to any Letter of Credit hereunder which increases the stated amount thereof
shall be subject to the same conditions applicable under this Section 2.2
(including the conditions set forth in Section 3.2) to the issuance of new
Letters of Credit, and no Issuing Bank shall be obligated to make any such
amendment, modification or supplement unless the Letter of Credit affected
thereby would have complied with such conditions had it originally been issued
hereunder, on the date of such amendment, modification or supplement, in such
amended, modified or supplemented form. The obligation of any Issuing Bank to
add any letter of credit hereto as contemplated by Section 2.2(a)(2) shall be
subject to the same conditions applicable under this Section 2.2 (including the
conditions set forth in Section 3.2) to the issuance of new Letters of Credit,
and no Issuing Bank shall be obligated to make any such addition unless the
Added Letter of Credit would have complied with such conditions had it
originally been issued hereunder on the date of such addition. In the event of
any conflict between any application, agreement or other instrument relating to
an Added Letter of Credit and the provisions of this Agreement, the provisions
of this Agreement shall control.

      (h) Interest Payable to Issuing Banks by Banks. To the extent that any
Bank shall fail to pay any amount required to be paid pursuant to Sections
2.2(d) or (e) on the due date therefor, such Bank shall pay interest to the
Issuing Bank owed such amount (through the Agent) on such amount from and
including such due date to but excluding the date such payment is made at a rate
per annum equal to the Federal Funds Rate.

      (i) Indemnification of the Banks, Issuing Banks and Agent. The Borrowers
hereby indemnify and hold harmless each Bank, each Issuing Bank and the Agent
from and against any and all claims, damages, losses, liabilities, costs, fees
and expenses that such Bank, such Issuing Bank or the Agent may incur (or that
may be claimed against such Bank, such Issuing Bank or the Agent by any Person
whatsoever) by reason of or in connection with the execution and delivery or
transfer of or payment or refusal to pay by each Issuing Bank under any Letter
of Credit (EXPRESSLY INCLUDING ANY SUCH CLAIM, DAMAGE, LOSS, LIABILITY, COST,
FEE OR EXPENSE ATTRIBUTABLE TO THE ORDINARY, SOLE OR CONTRIBUTORY NEGLIGENCE OF


                                      -23-


SUCH BANK, SUCH ISSUING BANK OR THE AGENT, AS THE CASE MAY BE, BUT EXCLUDING ANY
SUCH CLAIM, DAMAGE, LOSS, LIABILITY, COST, FEE OR EXPENSE ATTRIBUTABLE TO THE
GROSS NEGLIGENCE OR WILLFUL MISCONDUCT OF SUCH BANK, SUCH ISSUING BANK OR THE
AGENT, AS THE CASE MAY BE). IT IS THE INTENT OF THE PARTIES HERETO THAT EACH
BANK, EACH ISSUING BANK OR THE AGENT, AS THE CASE MAY BE, SHALL, TO THE EXTENT
PROVIDED IN THIS SECTION 2.2(I), BE INDEMNIFIED FOR ITS OWN ORDINARY, SOLE OR
CONTRIBUTORY NEGLIGENCE; provided that the Borrowers shall not be required to
indemnify any Bank, any Issuing Bank or the Agent for any claims, damages,
losses, liabilities, costs, fees or expenses to the extent, but only to the
extent, caused by (A) in the case of each Issuing Bank, the willful misconduct
or gross negligence of such Issuing Bank in determining whether a request
presented under any Letter of Credit complied with the terms of such Letter of
Credit or (B) in the case of any Bank, such Bank's failure to pay its Letter of
Credit Liabilities pursuant to Sections 2.2(d), (e) and (h).

      (j) Additional and Existing Letters of Credit. The Additional Letter of
Credit shall be deemed to be issued under this Agreement as of the Amendment
Date at the request of TWC and shall constitute a Letter of Credit hereunder for
all purposes (including Section 2.2(b) and Section 2.2(d)), and no notice
requesting issuance thereof shall be required hereunder. Each reference herein
to the issuance of a Letter of Credit shall include any such deemed issuance.
BofA shall be the Issuing Bank for purposes of the Additional Letter of Credit.
All fees (i) accrued on the Additional Letter of Credit to but excluding the
Amendment Date shall be for the account of BofA, (ii) accrued on the Additional
Letter Credit on and after the Amendment Date but before the date hereof shall
be for the account of BofA as "Issuing Bank" and the "Banks" (as those terms are
used in the 2004 Credit Agreement) as provided in the 2004 Credit Agreement, and
(iii) accruing on the Additional Letter of Credit on and after the date hereof
shall be for the account of BofA, as Issuing Bank hereunder, and the Banks as
provided herein. For the avoidance of doubt, the parties hereto acknowledge and
agree that all Existing Letters of Credit are deemed to be issued under this
Agreement by the Issuing Bank party thereto at the request of TWC and shall
constitute Letters of Credit hereunder for all purposes (including Section
2.2(b) and Section 2.2(d)), and no notice requesting issuance thereof shall be
required hereunder. Each reference herein to the issuance of a Letter of Credit
shall include any such deemed issuance. All fees accrued on the Existing Letters
of Credit to but excluding the date hereof shall be for the account of the
relevant "Issuing Bank" and the "Banks" (as those terms are used in the 2004
Credit Agreement) as provided in the 2004 Credit Agreement, and all fees
accruing on the Existing Letters of Credit on and after the date hereof shall be
for the account of the relevant Issuing Bank thereof and the Banks as provided
herein.

      (k) Cash Collateral. If any amounts are deposited in any LC Cash
Collateral Account in respect of any Borrower pursuant to Section 2.5(c), such
amounts shall be applied first, to reimburse the Collateral Agent for all costs,
fees, expenses and other amounts expended by it relating to such LC Cash
Collateral Account, second, to pay Reimbursement Obligations in respect of
Letters of Credit issued at the request of such Borrower outstanding at the time
of such deposit and, third, either (i) if at the time all such Letters of Credit
terminate and all such Reimbursement Obligations are paid no Event of Default
has occurred and is continuing (or if the Agent has not declared all amounts
payable hereunder by such Borrower to be due and payable), returned to such
Borrower or (ii) if at such time an Event of Default has occurred and is
continuing (and if the Agent has declared all amounts payable hereunder by such
Borrower to be due and payable), held by the Collateral Agent in an LC Cash
Collateral Account in respect of such Borrower in accordance with Section 6.2.

      (l) Applicability of ISP98 (ICC Publication No. 59). Unless otherwise
expressly agreed by an Issuing Bank and a Borrower when a Letter of Credit is
issued or except as otherwise specifically provided in respect of the Additional
Letter of Credit or an Added Letter of Credit, the rules of the "International
Standby Practices 1998" published by the Institute of International Banking Law
&


                                      -24-


Practice, Inc. (or such later version thereof as may be in effect at the time of
issuance) shall apply to each Letter of Credit.

      (m) Added Letters of Credit. Each Added Letter of Credit (i) shall be
deemed to be issued under this Agreement, as of the Added L/C Effective Date for
such Added Letter of Credit, at the request of the Borrower that gave the Notice
of Letter of Credit in respect of such Added Letter of Credit and (ii) as of
such Added L/C Effective Date, shall constitute a Letter of Credit issued
hereunder by the Issuing Bank specified in such Notice of Letter of Credit for
all purposes (including Section 2.2(b) and Section 2.2(d)). Each reference
herein to the issuance of a Letter of Credit shall include any such deemed
issuance. All fees accrued on a letter of credit that becomes an Added Letter of
Credit, to but excluding the Added L/C Effective Date for such Added Letter of
Credit shall be for the account of the entity that issued such Added Letter of
Credit, and all fees accruing on such letter of credit on and after such Added
L/C Effective Date shall be for the account of the relevant Issuing Bank thereof
and the Banks as provided herein.

      SECTION 2.3. Making the Revolving Credit Advances.

      (a) Each Revolving Credit Borrowing shall be made on notice, given not
later than 11:00 a.m. (New York City time) on the third Business Day prior to
the date of the proposed Revolving Credit Borrowing in the case of a Revolving
Credit Borrowing consisting of Eurodollar Rate Advances, or 10:00 a.m. (New York
City time) on the Business Day of the proposed Revolving Credit Borrowing in the
case of a Revolving Credit Borrowing consisting of Base Rate Advances, by the
Borrower requesting such Revolving Credit Borrowing to the Agent, which shall
give to each Bank prompt notice thereof. Each such notice of a Revolving Credit
Borrowing (a "Notice of Revolving Credit Borrowing") shall be by telephone,
confirmed immediately in writing, or telecopier in substantially the form of
Exhibit D-2 hereto, specifying therein the requested (i) date of such Revolving
Credit Borrowing, (ii) Type of Revolving Credit Advances, (iii) aggregate amount
of such Revolving Credit Borrowing, and (iv) in the case of a Revolving Credit
Borrowing consisting of Eurodollar Rate Advances, initial Interest Period for
each such Revolving Credit Advance. Each Bank shall, before 12:00 p.m. (New York
City time) on the date of such Revolving Credit Borrowing, make available for
the account of its Applicable Lending Office to the Agent at its address
referred to in Section 8.2 (excluding, for such purpose, any address to which
copies are to be sent), in same day funds, such Bank's ratable portion of such
Revolving Credit Borrowing. After the Agent's receipt of such funds, the Agent
will make such funds available to the Borrower requesting such Revolving Credit
Borrowing at such address; provided that the Agent shall not be required to make
such funds available if the applicable conditions set forth in Section 3.2 have
not been fulfilled.

      (b) Anything in Section 2.3(a) to the contrary notwithstanding, a Borrower
may not select Eurodollar Rate Advances for any Revolving Credit Borrowing if
the obligation of the Banks to make Eurodollar Rate Advances shall then be
suspended pursuant to Sections 2.3(e), 2.14 or 2.16.

      (c) No Borrower may select Eurodollar Rate Advances for any Revolving
Credit Borrowing if the aggregate amount of such Revolving Credit Borrowings is
less than $5,000,000.

      (d) Each Notice of Revolving Credit Borrowing shall be irrevocable and
binding on the Borrower delivering such notice. In the case of any Revolving
Credit Borrowing that the related Notice of Revolving Credit Borrowing specifies
is to be comprised of Eurodollar Rate Advances, the Borrower requesting such
Borrowing shall indemnify each Bank against any loss, cost or expense incurred
by such Bank as a result of any failure by such Borrower to fulfill on or before
the date specified in such Notice of Revolving Credit Borrowing for such
Revolving Credit Borrowing the applicable conditions set forth in Article III or
as a result of a cancellation pursuant to Section 2.3(f), including any loss
(excluding loss of anticipated profits), cost or expense incurred by reason of
the liquidation or reemployment of deposits or


                                      -25-


other funds acquired by such Bank to fund the Revolving Credit Advance to be
made by such Bank as part of such Revolving Credit Borrowing when such Revolving
Credit Advance, as a result of such failure or cancellation, is not made on such
date.

      (e) If the Agent is unable to determine the Eurodollar Rate for Eurodollar
Rate Advances, the obligation of the Banks to make, or to Convert Revolving
Credit Advances into, Eurodollar Rate Advances shall be suspended until the
Agent shall notify the Borrowers and the Banks that the circumstances causing
such suspension no longer exist, and, except as provided in Section 2.3(f), each
Revolving Credit Advance comprising any requested Revolving Credit Borrowing
shall be a Base Rate Advance.

      (f) If a Borrower has requested a proposed Revolving Credit Borrowing
consisting of Eurodollar Rate Advances and as a result of circumstances referred
to in Section 2.3(e), Section 2.14(b) or Section 2.16 such Revolving Credit
Borrowing would not consist of Eurodollar Rate Advances, such Borrower may, by
notice given not later than 3:00 p.m. (New York City time) at least one Business
Day prior to the date such proposed Revolving Credit Borrowing would otherwise
be made, cancel such Revolving Credit Borrowing, in which case such Revolving
Credit Borrowing shall be cancelled and no Revolving Credit Advances shall be
made as a result of such requested Revolving Credit Borrowing, but such Borrower
shall indemnify the Banks in connection with such cancellation as contemplated
by Section 2.3(d).

      (g) Unless the Agent shall have received notice from a Bank prior to the
date of any Revolving Credit Borrowing that such Bank will not make available to
the Agent such Bank's ratable portion of such Revolving Credit Borrowing, the
Agent may assume that such Bank has made such portion available to the Agent on
the date of such Revolving Credit Borrowing in accordance with Section 2.3(a)
and the Agent may, in reliance upon such assumption, make available to a
Borrower on such date a corresponding amount. If and to the extent that such
Bank shall not have so made such ratable portion available to the Agent, such
Bank and Borrower severally agree to repay to the Agent forthwith on demand such
corresponding amount together with interest thereon, for each day from the date
such amount is made available to such Borrower until the date such amount is
repaid to the Agent, at (i) in the case of such Borrower, the interest rate
applicable at the time to Revolving Credit Advances comprising such Revolving
Credit Borrowing and (ii) in the case of such Bank, the Federal Funds Rate. If
such Bank shall repay to the Agent such corresponding amount, such amount so
repaid shall constitute such Bank's Revolving Credit Advance as part of such
Revolving Credit Borrowing for purposes of this Agreement and such Borrower
shall be relieved of its obligations to repay on demand such amount under this
Section 2.3(g).

      (h) The failure of any Bank to make the Revolving Credit Advance to be
made by it as part of any Revolving Credit Borrowing shall not relieve any other
Bank of its obligation, if any, hereunder to make its Revolving Credit Advance
on the date of such Revolving Credit Borrowing, but no Bank shall be responsible
for the failure of any other Bank to make any Revolving Credit Advance to be
made by such other Bank.

      SECTION 2.4. Reduction of the Commitments. Each Borrower shall have the
right, upon at least three Business Days notice to the Agent, to terminate in
whole or reduce ratably in part (i) the Unused Revolving Credit Commitments for
such Borrower and (ii) the unused portions of the Letter of Credit Commitments;
provided that each partial reduction shall be in the aggregate amount of
$5,000,000 or an integral multiple of $1,000,000 in excess thereof and shall be
made ratably among the Banks or Issuing Banks, as the case may be, in accordance
with their respective Commitments for such Borrower or Letter of Credit
Commitments, as the case may be, and provided further that the amount of the
Letter of Credit Commitment of any Issuing Bank shall not be reduced to an
amount which is less than the


                                      -26-


aggregate amount of all Letter of Credit Liabilities in respect of all Letters
of Credit issued or deemed issued by such Issuing Bank; and provided further
that the Revolving Credit Commitments for TWC shall not be reduced to an amount
which is less than the greatest, for any Borrower, of the sum of (i) the
aggregate outstanding principal amount of Revolving Credit Advances owed by such
Borrower plus (ii) the aggregate amount of all Letter of Credit Liabilities in
respect of Letters of Credit issued at the request of such Borrower; and
provided further that the Revolving Credit Commitments for any Borrower shall
not be reduced to an amount which is less than the sum of (i) the aggregate
outstanding principal amount of Revolving Credit Advances owed by such Borrower
plus (ii) the aggregate amount of all Letter of Credit Liabilities in respect of
Letters of Credit issued at the request of such Borrower; and provided further
that the Revolving Credit Commitments for TWC shall not be reduced to an amount
which is less than the aggregate amount of the Letter of Credit Commitments.
Each termination or reduction of any Commitment shall be permanent.

      SECTION 2.5. Prepayments. (a) Each Borrower may, upon notice to the Agent,
(i) before 10:00 a.m. (New York City time) for Base Rate Advances on the date of
prepayment and (ii) upon at least two Business Days' notice to the Agent for
Eurodollar Rate Advances, stating the proposed date and aggregate principal
amount of the prepayment, and if such notice is given such Borrower shall,
prepay the outstanding principal amount of the Revolving Credit Advances
comprising part of the same Revolving Credit Borrowing in whole or ratably in
part, together with accrued interest to the date of such prepayment on the
principal amount prepaid and amounts, if any, required to be paid pursuant
Section 8.4(c) as a result of such prepayment; provided that each prepayment
pursuant to this Section 2.5(a) shall be in an aggregate principal amount of
$5,000,000 or an integral multiple of $1,000,000 in excess thereof.

      (b) Additionally, if at any date the sum of the aggregate amount of all
Revolving Credit Advances owed to any Bank by any Borrower plus the aggregate
amount of all Letter of Credit Liabilities held by such Bank for all Letters of
Credit issued at the request of such Borrower exceeds such Bank's Revolving
Credit Commitment for such Borrower at such date, such Borrower shall, on such
date, ratably repay the Revolving Credit Advances owed by such Borrower in a
principal amount necessary so that (after giving effect to such repayment) the
sum, for each Bank, of the aggregate amount of all Revolving Credit Advances
owed to such Bank by such Borrower plus the aggregate amount of all Letter of
Credit Liabilities held by such Bank for all Letters of Credit issued at the
request of such Borrower does not exceed such Bank's Revolving Credit Commitment
for such Borrower at such date.

      (c) At the time of each payment pursuant to Section 2.5(b) by a Borrower,
such Borrower shall also pay accrued interest to the date of such payment on the
principal amount paid and amounts, if any, required to be paid pursuant to
Section 8.4(c) as a result of such payment. To the extent that any amount would
be required hereunder to be applied to Revolving Credit Advances owed by any
Borrower but for the fact that no Revolving Credit Advances to such Borrower
remain outstanding, such Borrower will cause such amount first, to be paid on
any outstanding unreimbursed drawings under Letters of Credit issued at the
request of such Borrower and, second to be deposited in an LC Cash Collateral
Account in respect of such Borrower.

      (d) All amounts received by the Collateral Agent pursuant to any Security
Document shall be applied first, to reimburse the Collateral Agent for all
costs, fees, expenses and other amounts to the extent provided in such Security
Document, second, to ratably pay the principal of and interest of the Revolving
Credit Advances and unpaid drawings under Letters of Credit, third to ratably
pay all other Obligations, and fourth to be deposited in one or more LC Cash
Collateral Accounts to the extent any Letters of Credit are outstanding.


                                      -27-


     SECTION 2.6. Increased Costs.

     (a) If any Bank or Issuing Bank determines that (i) the introduction of or
any change in or in the interpretation, application or applicability of any law
or regulation or (ii) the compliance with any guideline issued or request made
by any central bank or other governmental or monetary authority (whether or not
having the force of law), in each case introduced, changed, issued or made after
the Effective Date (in the case of each Bank or Issuing Bank which was a party
to the 2004 Credit Agreement on the Effective Date) or after the effective date
of the relevant document (a Transfer Agreement, Revolving Credit Commitment
Increase Agreement, Letter of Credit Commitment Increase Agreement or this
Agreement) pursuant to which a Person becomes a Bank or an Issuing Bank (in the
case of each other Bank or Issuing Bank), affects or would affect the amount of
capital required or expected to be maintained by such Bank or Issuing Bank, as
the case may be, or any corporation controlling such Bank or Issuing Bank, as
the case may be, and that the amount of such capital is increased by or based
upon the existence of such Bank's or such Issuing Bank's, as the case may be,
commitment to lend hereunder, issue Letters of Credit or purchase participations
in Letters of Credit and other commitments of this type, then, upon demand by
such Bank or Issuing Bank, as the case may be (with a copy of such demand and
related certificate (which certificate shall specify in reasonable detail the
nature of such change in capital requirements, the proposed (or actual)
compliance change to be adopted by the applicable Bank or Issuing Bank and the
calculations upon which any compensation is claimed hereunder) to the Agent),
the Borrowers shall immediately pay to the Agent within five Business Days of
receipt of such demand for the account of such Bank or Issuing Bank, as the case
may be, from time to time as specified by such Bank or Issuing Bank, as the case
may be, additional amounts sufficient to compensate such Bank or Issuing Bank,
as the case may be, or such corporation in the light of such circumstances, to
the extent that such Bank or Issuing Bank, as the case may be, reasonably
determines such increase in capital to be allocable to the existence of such
Bank's or such Issuing Bank's, as the case may be, commitment to lend, issue
Letters of Credit or purchase participations in Letters of Credit hereunder. A
certificate as to the amount of such additional amounts, submitted to the
Borrower that is obligated to pay such amount and the Agent by such Bank or
Issuing Bank, as the case may be, shall be prima facie evidence of the amount of
such additional amounts absent manifest error. No Bank or Issuing Bank shall
have any right to recover any additional amounts from a Borrower under this
Section 2.6(a) for any period more than 90 days prior to the date such Bank or
Issuing Bank, as the case may be, notifies such Borrower of any such compliance.

     (b) If, due to either (i) the introduction of or any change (other than any
change by way of imposition or increase of reserve requirements included in the
Eurodollar Rate Reserve Percentage) in or in the interpretation, application or
applicability of any law or regulation or (ii) the compliance with any guideline
issued or request made by any central bank or other governmental or monetary
authority (whether or not having the force of law), in each case introduced,
changed, issued or made after the Effective Date (in the case of each Bank which
was a party to the 2004 Credit Agreement on the Effective Date) or after the
effective date of the relevant document (a Transfer Agreement, Revolving Credit
Commitment Increase Agreement or this Agreement) pursuant to which a Person
becomes a Bank (in case of each other Bank), there shall be any increase in the
cost to any Bank of agreeing to make or making, funding or maintaining
Eurodollar Rate Advances to any Borrower, from that in effect at the Effective
Date or at the date of such relevant document, as the case may be, then such
Borrower shall from time to time, upon demand by such Bank (with a copy of such
demand to the Agent), pay to the Agent for the account of such Bank additional
amounts sufficient to compensate such Bank for such increased cost. A
certificate as to the amount of such increased cost, submitted to such Borrower
and the Agent by such Bank, shall be prima facie evidence of the amount of such
increased cost absent manifest error. No Bank shall have the right to recover
any such increased costs for any period more than 90 days prior to the date such
Bank notifies such Borrower of any such introduction, change, compliance or
proposed compliance.

                                      -28-

     (c) In the event that any Bank (other than a Bank that is also an Issuing
Bank) (i) makes a demand for payment under Section 2.8 or 2.17 or this Section
2.6, or (ii) does not agree to provide its consent or agree to any amendment or
waiver pursuant to Section 8.1 where such consent or agreement to provide an
amendment or waiver is required of all the Banks hereto, TWC may within 90 days
of such demand or non-consent, if no Default or Event of Default then exists,
replace such Bank with another commercial bank in accordance with all of the
provisions of the second and third sentences of Section 8.5(a), and clauses (b)
and (d) of Section 8.5 (including execution of an appropriate Transfer
Agreement); provided that (v) all obligations of such Bank to lend hereunder or
purchase participations in Letters of Credit shall be terminated and the Letter
of Credit Interests held by such Bank and Notes payable to such Bank and all
other obligations owed to such Bank hereunder shall be purchased in full without
recourse at par plus accrued interest and fees at or prior to such replacement,
(w) such replacement bank shall be an Eligible Assignee, (x) such replacement
bank shall, from and after such replacement, be deemed for all purposes to be a
"Bank" hereunder with a Revolving Credit Commitment for each Borrower and Letter
of Credit Liabilities in the amount of the Revolving Credit Commitment for each
Borrower and Letter of Credit Liabilities of such Bank being replaced,
immediately prior to such replacement (plus, if such replacement bank is already
a Bank prior to such replacement the respective Revolving Credit Commitments for
each Borrower and Letter of Credit Liabilities of such Bank prior to such
replacement), as such amount may be changed from time to time pursuant hereto,
and shall have all of the rights, duties and obligations hereunder of the Bank
being replaced, including obligations under Section 2.2, (y) such other actions
shall be taken by the Borrowers, such Bank and such replacement bank as may be
appropriate to effect the replacement of such Bank with such replacement bank on
terms such that such replacement bank has all of the rights, duties and
obligations hereunder as such Bank (including specification of the information
contemplated by Schedule I as to such replacement bank), and (z) no Bank or
Issuing Bank shall be required to increase any Commitment it may have or to
replace such Bank being replaced.

     (d) Before making any demand under this Section 2.6, each Bank agrees to
use reasonable efforts (consistent with its internal policy and legal and
regulatory restrictions) to designate a different Applicable Lending Office if
the making of such a designation would avoid the need for, or reduce the amount
of, such increased cost and would not, in the reasonable judgment of such Bank,
be otherwise disadvantageous to such Bank.

     SECTION 2.7. Payments and Computations.

     (a) Each Borrower shall make each payment hereunder to be made by it not
later than 11:00 a.m. (New York City time) on the day when due in Dollars to the
Agent at its address referred to in Section 8.2 (excluding, for such purpose,
any address to which copies are to be sent), in each case in same day funds,
without deduction, counterclaim or offset of any kind. The Agent will promptly
thereafter cause to be distributed to the Banks like funds relating to the
payment of principal, interest or any fees payable to the Banks for the account
of their respective Applicable Lending Offices, and like funds relating to the
payment of any other amount payable to any Bank or Issuing Bank to such Bank or
Issuing Bank, as the case may be, for the account of its Applicable Lending
Office, in each case to be applied in accordance with the terms of this
Agreement. The Agent will promptly pay to the Collateral Agent like funds
relating to the payment of any amount payable to the Collateral Agent. In no
event shall any Bank be entitled to share any fee paid to the Agent or
Collateral Agent pursuant to Section 2.11(a), any other fee paid to the Agent or
Collateral Agent, as such, any amount applied to reimburse the Collateral Agent
as contemplated by Section 2.2(k), Section 2.5(d), Section 6.2 or any other
provision of any Credit Document or any Fronting Fee, other fee, cost or charge
paid to an Issuing Bank pursuant to Section 2.11(b)(i).

                                      -29-

     (b) (i) All computations of interest based on clause (a) of the definition
herein of "Base Rate" shall be made by the Agent on the basis of a year of 365
or 366 days, as the case may be, and (ii) all computations of Letter of Credit
Fees, Commitment Fees, Fronting Fees and all other fees and of interest based on
the Eurodollar Rate, the Federal Funds Rate and interest pursuant to Section
2.17 shall be made by the Agent on the basis of a year of 360 days, in each case
for the actual number of days (including the first day but excluding the last
day) occurring in the period for which such interest, Letter of Credit Fees,
Commitment Fees, Fronting Fees or other fees are payable. Each determination by
the Agent of an interest rate or fee hereunder shall be conclusive and binding
for all purposes, absent manifest error.

     (c) Whenever any payment hereunder shall be stated to be due on a day other
than a Business Day, such payment shall be made on the next succeeding Business
Day, and such extension of time shall in such case be included in the
computation of payment of interest, Commitment Fee, Letter of Credit Fee,
Fronting Fee or any other fee hereunder, as the case may be; provided, however,
that, if such extension would cause payment of interest on or principal of
Eurodollar Rate Advances to be made in the next following calendar month, such
payment shall be made on the next preceding Business Day.

     (d) Unless the Agent shall have received notice from a Borrower prior to
the date on which any payment is due by such Borrower to any Bank hereunder that
such Borrower will not make such payment in full, the Agent may assume that such
Borrower has made such payment in full to the Agent on such date and the Agent
may, in reliance upon such assumption, cause to be distributed to each Bank on
such due date an amount equal to the amount then due such Bank hereunder. If and
to the extent such Borrower shall not have so made such payment in full to the
Agent, each Bank shall repay to the Agent forthwith on demand such amount
distributed to such Bank together with interest thereon, for each day from the
date such amount is distributed to such Bank until the date such Bank repays
such amount to the Agent, at the Federal Funds Rate.

     SECTION 2.8. Taxes.

     (a) Any and all payments by any Borrower hereunder shall be made, in
accordance with Section 2.7, free and clear of and without deduction for any and
all present or future taxes, levies, imposts, deductions, charges or
withholdings with respect thereto, and all liabilities with respect thereto,
excluding in the case of each Bank, each Issuing Bank and the Agent, (i) taxes
imposed on its net income or net profits, and franchise taxes imposed on it, by
the jurisdiction under the laws of which such Bank, such Issuing Bank or the
Agent (as the case may be) is organized or any political subdivision thereof and
(ii) taxes imposed as a result of a present or former connection between such
Bank, such Issuing Bank or the Agent, as the case may be, and the jurisdiction
imposing such tax or any political subdivision thereof (other than any such
connection arising solely from such Bank, such Issuing Bank or the Agent, as the
case may be, having executed or delivered, or performed its obligations or
received a payment under, or taken any other action related to any Credit
Document) and, in the case of each Bank, taxes imposed on its net income or net
profits, and franchise taxes imposed on it, by the jurisdiction of such Bank's
Applicable Lending Office or any political subdivision thereof (all such
non-excluded taxes, levies, imposts, deductions, charges, withholdings and
liabilities being hereinafter referred to as "Taxes"). If any Borrower shall be
required by law to deduct any Taxes from or in respect of any sum payable
hereunder or under any Note to any Bank, any Issuing Bank or the Agent, (i) the
sum payable shall be increased as may be necessary so that after making all
required deductions for Taxes (including deductions for Taxes applicable to
additional sums payable under this Section 2.8) such Bank, such Issuing Bank or
the Agent, as the case may be, receives an amount equal to the sum it would have
received had no such deductions for Taxes been made, (ii) such Borrower shall
make such deductions and (iii) such Borrower shall pay the full amount deducted
to the relevant taxation authority or other authority in accordance with
applicable law.

                                      -30-

     (b) In addition, each Borrower agrees to pay all present or future filing
or recording fees, stamp or documentary taxes and all other excise or property
taxes, charges or similar levies which arise from any payment made by such
Borrower hereunder or from the execution, delivery, filing, recording or
registration of, or otherwise with respect to, any Credit Document (herein
referred to as "Other Taxes").

     (c) Each Borrower will indemnify each Bank, each Issuing Bank and the Agent
for the full amount of Taxes or Other Taxes (including any Taxes or Other Taxes
imposed by any jurisdiction on amounts payable under this Section 2.8) owed and
paid by such Bank, such Issuing Bank or the Agent, as the case may be, and any
liability (including penalties, interest and expenses) arising therefrom or with
respect thereto. This indemnification shall be made within 30 days from the date
such Bank, such Issuing Bank or the Agent, as the case may be, makes written
demand therefor; provided that such Borrower shall have no liability pursuant to
this clause (c) of this Section 2.8 to indemnify a Bank, an Issuing Bank or the
Agent for Taxes or Other Taxes which were paid by such Bank, such Issuing Bank
or the Agent, as the case may be, more than ninety days prior to such written
demand for indemnification.

     (d) In the event that a Bank, an Issuing Bank or the Agent receives a
written communication from any governmental authority with respect to an
assessment or proposed assessment of any Taxes, such Bank, such Issuing Bank or
Agent, as the case may be, shall promptly notify TWC in writing and provide TWC
with a copy of such communication. The Agent's, an Issuing Bank's or a Bank's
failure to provide a copy of such communication to TWC shall not relieve TWC of
any of its obligations hereunder.

     (e) Promptly following payment of Taxes by or at the direction of any
Borrower, such Borrower will furnish to the Agent, at its address referred to in
Section 8.2, the original or a certified copy of a receipt evidencing payment
thereof (or, if no such receipt is reasonably available, other evidence of
payment reasonably acceptable to the Agent). Should any Bank, any Issuing Bank
or the Agent ever receive any refund, credit or deduction from any taxing
authority to which such Bank, such Issuing Bank or the Agent, as the case may
be, would not be entitled but for the payment by such Borrower of Taxes or Other
Taxes as required by this Section 2.8 (it being understood that the decision as
to whether or not to claim, and if claimed, as to the amount of any such refund,
credit or deduction shall be made by such Bank, such Issuing Bank or the Agent,
as the case may be, in its reasonable judgment), such Bank, such Issuing Bank or
the Agent, as the case may be, thereupon shall repay to such Borrower an amount
with respect to such refund, credit or deduction equal to any net reduction in
taxes actually obtained by such Bank, such Issuing Bank or the Agent, as the
case may be, and determined by such Bank, such Issuing Bank or the Agent, as the
case may be, to be attributable to such refund, credit or deduction.

     (f) Each Bank organized under the laws of a jurisdiction outside the United
States shall on or prior to the date of its execution and delivery of this
Agreement in the case of each Bank which is a party to this Agreement on the
date this Agreement becomes effective and on the date the Transfer Agreement or
Revolving Credit Commitment Increase Agreement pursuant to which it becomes a
Bank is first effective in the case of each other Bank, and from time to time
thereafter as necessary or appropriate (but only so long thereafter as such Bank
remains lawfully able to do so), provide the Agent and each Borrower with two
original Internal Revenue Service Forms W-8BEN or W-8ECI (or, in the case of a
Bank that has provided a certificate to the Agent that it is not (i) a "bank" as
that term is used in Section 881(c)(3)(A) of the Code, (ii) a ten-percent
shareholder (within the meaning of Section 871(h)(3)(B) of the Code) of such
Borrower or (iii) a controlled foreign corporation related to such Borrower
(within the meaning of Section 864(d)(4) of the Code), Internal Revenue Service
Forms W-8BEN), or any successor or other form prescribed by the Internal Revenue
Service, certifying that such Bank is exempt from or entitled to a reduced rate
of United States withholding tax on payments pursuant to this Agreement or any
other Credit Document or, in the case of a Bank that has certified that it is
not a "bank" as described above, certifying that such Bank is a foreign
corporation. If the forms provided by a Bank at the time such Bank first becomes
a party to this Agreement (or at the time such Bank first became a party to the

                                      -31-

2004 Credit Agreement in the case of any Bank that was a party thereto) indicate
a United States interest withholding tax rate in excess of zero, withholding tax
at such rate shall be considered excluded from Taxes unless and until such Bank
provides the appropriate forms certifying that a lesser rate applies, whereupon
withholding tax at such lesser rate only shall be considered excluded from Taxes
for periods governed by such forms.

     (g) For any period with respect to which a Bank has failed to provide any
Borrower with the appropriate form, certificate or other document required by
subsection (f) of this Section 2.8 (other than if such failure is due to a
change in the applicable law, or in the interpretation or application thereof,
occurring after the date on which a form, certificate or other document
originally was required to be provided) such Bank shall not be entitled to
indemnification under subsection (a) or (c) of this Section 2.8 with respect to
Taxes imposed by the United States by reason of such failure; provided, however,
that should a Bank become subject to Taxes because of its failure to deliver a
form, certificate or other document required hereunder, the Borrowers shall take
such steps as such Bank shall reasonably request (at such Bank's expense) to
assist such Bank in recovering such Taxes.

     (h) Any Bank claiming any additional amounts payable pursuant to this
Section 2.8 agrees to use reasonable efforts to change the jurisdiction of its
Applicable Lending Office if the making of such a change would avoid the need
for, or reduce the amount of, any such additional amounts that may thereafter
accrue and would not, in the reasonable judgment of such Bank, be otherwise
materially disadvantageous to such Bank.

     (i) If a Borrower determines in good faith that a reasonable basis exists
for contesting a Tax, the relevant Bank, or the Agent, as applicable, shall
provide reasonable cooperation to such Borrower in challenging such Tax at such
Borrower's expense and if requested by such Borrower in writing; provided,
however, that no Bank shall be required to take any action hereunder which, in
the reasonable discretion of such Bank, would cause such Bank or its Applicable
Lending Office to suffer a legal, regulatory or material economic disadvantage.

     (j) Without prejudice to the survival of any other agreement of the
Borrowers hereunder, the agreements and obligations of the Borrowers contained
in this Section 2.8 shall survive the payment in full of principal and interest
hereunder and the Termination Date.

     (k) Notwithstanding any provision of this Agreement or the Notes to the
contrary, this Section 2.8 shall be the sole provision governing indemnities for
and claims for Taxes under this Agreement.

     (l) Notwithstanding any other provision in this Section 2.8, no additional
amount shall be required to be paid by any Borrower under Section 2.8(a) or
2.8(c) to any Bank organized under the laws of a jurisdiction outside the United
States in respect of Taxes or any liabilities (including penalties, interest and
expenses arising therefrom or with respect thereto), except to the extent that
any change after the Effective Date (in the case of each Bank which was a party
to the 2004 Credit Agreement on the Effective Date) or after the effective date
of the relevant document (a Transfer Agreement, Revolving Credit Commitment
Increase Agreement or this Agreement) pursuant to which a Person becomes a Bank
(in case of each other Bank) in any such requirement for a deduction,
withholding or payment of Taxes described in this Section 2.8 shall result in an
increase in the rate of such deduction, withholding or payment from that in
effect at the Effective Date (in the case of each Bank which was a party to the
2004 Credit Agreement on the Effective Date) or at the date of such relevant
document (in the case of each other Bank). For avoidance of doubt, this Section
2.8(l) does not apply to Other Taxes.

                                      -32-

     SECTION 2.9. Sharing of Payments, Etc. If any Bank shall obtain any payment
(whether voluntary or involuntary, or through the exercise of any right of
set-off or otherwise) on account of the Revolving Credit Advances owed to it or
its Letter of Credit Interest (other than pursuant to Section 2.6, 2.8, 2.17,
8.4(b) or 8.4(c)) in excess of its ratable share of payments on account of all
Revolving Credit Advances and Letter of Credit Interests obtained by all the
Banks, such Bank shall forthwith purchase from the other Banks such
participations in the Revolving Credit Advances and Letter of Credit Interests
of such other Banks as shall be necessary to cause such purchasing Bank to share
the excess payment ratably with each of them; provided that if all or any
portion of such excess payment is thereafter recovered from such purchasing
Bank, such purchase from each Bank shall be rescinded and such Bank shall repay
to the purchasing Bank the purchase price to the extent of such Bank's ratable
share (according to the proportion of (i) the amount of the participation
purchased from such Bank as a result of such excess payment to (ii) the total
amount of such excess payment) of such recovery together with an amount equal to
such Bank's ratable share (according to the proportion of (i) the amount of such
Bank's required repayment to (ii) the total amount so recovered from the
purchasing Bank) of any interest or other amount paid or payable by the
purchasing Bank in respect of the total amount so recovered. Each Borrower
agrees that any Bank so purchasing a participation from another Bank pursuant to
this Section 2.9 may, to the fullest extent permitted by law, exercise all its
rights of payment (including the right of set-off) with respect to such
participation as fully as if such Bank were the direct creditor of such Borrower
in the amount of such participation. For avoidance of doubt, in no event shall
the Borrowers be liable for duplicative payments under this Section 2.9 in
respect of any Obligations.

     SECTION 2.10. Evidence of Debt. (a) Each Bank and Issuing Bank shall
maintain in accordance with its usual practice an account or accounts evidencing
the indebtedness of each Borrower to such Bank or Issuing Bank resulting from
each Revolving Credit Advance or Letter of Credit Interest owing to such Bank or
Issuing Bank, as the case may be, from time to time, including the amounts of
principal and interest payable and paid to such Bank or Issuing Bank from time
to time hereunder. Each Borrower agrees that upon notice by any Bank to such
Borrower (with a copy of such notice to the Agent) to the effect that a
promissory note or other evidence of indebtedness is required or appropriate in
order for such Bank to evidence (whether for purposes of pledge, enforcement or
otherwise) the Revolving Credit Advances to such Borrower owing to, or to be
made by, such Bank, such Borrower shall promptly execute and deliver to such
Bank, with a copy to the Agent, a Note in substantially the form of Exhibit G
hereto payable to the order of such Bank. All references to Notes in the Credit
Documents shall mean Notes, if any, to the extent issued hereunder.

     (b) In addition to the entries contemplated by Section 8.5(c), the Register
maintained by the Agent shall set forth (i) the date and amount of each Letter
of Credit and Revolving Credit Borrowing made hereunder, the Type of Revolving
Credit Advances comprising such Revolving Credit Borrowing and, if appropriate,
the Interest Period applicable thereto, and (ii) the amount of any interest due
and payable from each Borrower to each Bank hereunder.

     (c) Entries made in good faith by the Agent in the Register pursuant to
subsection (b) above, and by each Bank or Issuing Bank in its account or
accounts pursuant to subsection (a) above, shall be prima facie evidence of the
matters set forth therein, absent manifest error; provided, however that the
failure of the Agent or such Bank or Issuing Bank to make an entry, or any
finding that an entry is incorrect, in the Register or such account or accounts
shall not limit or otherwise affect the obligations of any Credit Party under
any Credit Document.

                                      -33-

     SECTION 2.11. Fees.

     (a) Agent's and Collateral Agent's Fees. TWC agrees to pay to the Agent and
the Collateral Agent, for their respective sole account, such fees as may be
separately agreed to in writing by TWC and the Agent and the Collateral Agent.

     (b) Letter of Credit Fees.

          (i) Fronting Fee and Other Fees and Charges of Issuing Banks. Each
Borrower agrees to pay to the Agent for the account of each Issuing Bank a
fronting fee (a "Fronting Fee") based on the Available Amount of each Letter of
Credit issued at the request of such Borrower (for the stated duration thereof)
issued by such Issuing Bank in an amount equal to 0.15% per annum. All Fronting
Fees payable pursuant to this Section 2.11(b)(i) shall be payable in arrears on
the last Business Day of each Fiscal Quarter, on the Termination Date and on
demand from time to time during the continuance of an Event of Default. In
addition, each Borrower shall pay directly to each Issuing Bank for its own
account the customary issuance, presentation, amendment and other processing
fees, and other standard costs and charges, of such Issuing Bank relating to
Letters of Credit issued at the request of such Borrower as from time to time in
effect. Such customary fees and standard costs and charges are due and payable
on demand and are nonrefundable.

          (ii) Participating Banks. Each Borrower agrees to pay to the Agent for
the account of each Bank a letter of credit fee (a "Letter of Credit Fee") based
on such Bank's LC Participation Percentage of the average daily aggregate
Available Amount of all Letters of Credit issued at the request of such Borrower
outstanding from time to time at a rate per annum equal from time to time to the
Applicable Margin for Eurodollar Rate Advances for such Borrower in effect from
time to time (for the stated duration thereof). All amounts payable pursuant to
this Section 2.1l(b)(ii) shall be paid in arrears on the last Business Day of
each Fiscal Quarter, on the Termination Date and on demand from time to time
during the continuance of an Event of Default.

     (c) Commitment Fees. TWC agrees to pay to the Agent for the account of each
Bank a commitment fee (a "Commitment Fee"), in an amount equal to the Applicable
Commitment Fee Rate in effect from time to time multiplied by the average daily
amount of such Bank's Unused Revolving Credit Commitment for TWC (for purposes
of computing Commitment Fees only, Revolving Credit Advances made to any
Borrower shall be considered to have been made to TWC and Letters of Credit
issued at the request of any Borrower shall be considered to have been issued at
the request of TWC, and accordingly, for purposes of computing Commitment Fees
only, both shall be considered to be usage of such Revolving Credit Commitment
for TWC). All amounts payable pursuant to this Section 2.11(c) shall be paid in
arrears on the last Business Day of each Fiscal Quarter and on the Termination
Date.

     SECTION 2.12. Repayment of Revolving Credit Advances. Each Borrower shall
repay to the Agent for the ratable account of the Banks on the date set forth in
clause (i) of the definition herein of Termination Date, or such earlier date as
may be applicable pursuant to Article VI, the aggregate principal amount of the
Revolving Credit Advances made to such Borrower then outstanding.

     SECTION 2.13. Interest.

     (a) Scheduled Interest. Each Borrower shall pay interest on the unpaid
principal amount of each Revolving Credit Advance made to such Borrower from the
date of such Revolving Credit Advance until such principal amount shall be paid
in full, at the following rates per annum:

                                      -34-

          (i) Base Rate Advances. During such periods as such Revolving Credit
Advance is a Base Rate Advance, a rate per annum equal at all times to the sum
of (x) the Base Rate in effect from time to time plus (y) the Applicable Margin
in effect from time to time for such Borrower as to Base Rate Advances, payable
in arrears quarterly on the last Business Day of each Fiscal Quarter during such
periods and on the date such Base Rate Advance shall be Converted or paid in
full.

          (ii) Eurodollar Rate Advances. During such periods as such Revolving
Credit Advance is a Eurodollar Rate Advance, a rate per annum equal at all times
during each Interest Period for such Revolving Credit Advance to the sum of (x)
the Eurodollar Rate for such Interest Period for such Revolving Credit Advance
plus (y) the Applicable Margin in effect from time to time for such Borrower as
to Eurodollar Rate Advances, payable in arrears on the last day of such Interest
Period and, if such Interest Period has a duration of more than three months, on
each day that occurs during such Interest Period every three months from the
first day of such Interest Period and on the date such Eurodollar Rate Advance
shall be Converted or paid in full.

     (b) Default Interest. Upon the occurrence and during the continuance of an
Event of Default, each Borrower shall pay interest on (i) the past due principal
amount (if any) of (x) each Revolving Credit Advance owing to each Bank by such
Borrower, payable in arrears on demand and (y) each past due Reimbursement
Obligation (if any) owing by such Borrower, payable in arrears on demand, at a
rate per annum equal to 2% per annum above the rate per annum required to be
paid on such Revolving Credit Advance pursuant to Section 2.13(a) or such rate
per annum required to be paid on such Reimbursement Obligation pursuant to
Section 2.2(c) and (ii) to the fullest extent permitted by law, the amount of
any interest, Fronting Fee, Commitment Fee, Letter of Credit Fee or any other
fee or other amount payable hereunder that is not paid when due (giving effect
to any grace period), from the date such amount shall be due until such amount
shall be paid in full, payable in arrears on the date such amount shall be paid
in full and on demand, at a rate per annum equal at all times to 2% per annum
above the rate per annum required to be paid on Base Rate Advances owed by such
Borrower pursuant to Section 2.13(a)(i).

     SECTION 2.14. Interest Rate Determination.

     (a) The Agent shall give prompt notice to the Borrowers and the Banks of
the applicable interest rate determined by the Agent for purposes of Section
2.13(a)(i) or 2.13(a)(ii).

     (b) If, with respect to any Eurodollar Rate Advances, the Majority Banks
notify the Agent that either (1) the Eurodollar Rate for any Interest Period for
such Eurodollar Rate Advances will not adequately reflect the cost to such
Majority Banks of making, funding or maintaining their respective Eurodollar
Rate Advances for such Interest Period, or (2) Dollar deposits for the relevant
amounts and Interest Period for their respective Eurodollar Rate Advances are
not available to them in the London interbank market, the Agent shall forthwith
so notify the Borrowers and the Banks, whereupon (i) each Eurodollar Rate
Advance will automatically, on the last day of the then existing Interest Period
therefor, Convert into a Base Rate Advance, and (ii) the obligation of the Banks
to make, or to Convert Revolving Credit Advances into, Eurodollar Rate Advances
shall be suspended until the Agent shall notify the Borrowers and the Banks that
the circumstances causing such suspension no longer exist.

     (c) If a Borrower shall fail to select the duration of any Interest Period
for any Eurodollar Rate Advances in accordance with the provisions contained in
the definition of "Interest Period" in Section 1.01, the Agent will forthwith so
notify such Borrower and the Banks and such Revolving Credit Advances will
automatically, on the last day of the then existing Interest Period therefor,
Convert into Base Rate Advances.

                                      -35-

     (d) On the date on which the aggregate unpaid principal amount of
Eurodollar Rate Advances comprising any Revolving Credit Borrowing shall be
reduced, by payment or prepayment or otherwise, to less than $5,000,000, such
Revolving Credit Advances shall automatically Convert into Base Rate Advances
and the applicable Borrower shall pay any amounts required to be paid pursuant
Section 8.4(c) as a result of such Conversion.

     (e) If any Event of Default exists as to any Borrower, (i) each Eurodollar
Rate Advance made to such Borrower will automatically, on the last day of the
then existing Interest Period therefor, Convert into a Base Rate Advance and
(ii) the obligation of the Banks to make Eurodollar Rate Advances to such
Borrower, and to Convert Advances made to such Borrower into Eurodollar Rate
Advances, shall be suspended.

     SECTION 2.15. Optional Conversion of Revolving Credit Advances. Any
Borrower may on any Business Day, upon notice given to the Agent not later than
11:00 a.m. (New York City time) on the third Business Day prior to the date of
the proposed Conversion and subject to the provisions of Sections 2.14 and 2.16,
Convert all Revolving Credit Advances of one Type comprising the same Revolving
Credit Borrowing made to such Borrower into Revolving Credit Advances of the
other Type; provided, however, that any Conversion of Eurodollar Rate Advances
into Base Rate Advances shall be made only on the last day of an Interest Period
for such Eurodollar Rate Advances and any Conversion of Base Rate Advances into
Eurodollar Rate Advances shall be in an amount of $5,000,000 or an integral
multiple of $1,000,000 in excess thereof. Each such notice of a Conversion
shall, within the restrictions specified above, specify (a) the date of such
Conversion, (b) the Revolving Credit Advances to be Converted and (c) if such
Conversion is into Eurodollar Rate Advances, the duration of the initial
Interest Period for each such Revolving Credit Advance. Each notice of
Conversion shall be irrevocable and binding on such Borrower.

     SECTION 2.16. Illegality. Notwithstanding any other provision of this
Agreement, if any Bank shall notify the Agent that the introduction of or any
change in or in the interpretation of any law or regulation makes it unlawful,
or any central bank or other governmental authority having relevant jurisdiction
asserts that it is unlawful, for any Bank or its Eurodollar Lending Office to
perform its obligations hereunder to make Eurodollar Rate Advances or to fund or
maintain Eurodollar Rate Advances hereunder, (a) each Eurodollar Rate Advance
will automatically, upon such demand, Convert into a Base Rate Advance and (b)

Revolving Credit Advances into Eurodollar Rate Advances shall be suspended until
the Agent shall notify the Borrowers and the Banks that the circumstances
causing such suspension no longer exist.

     SECTION 2.17. Additional Interest on Eurodollar Rate Advances. Each
Borrower shall pay to each Bank, so long as such Bank shall be required under
regulations of the Federal Reserve Board to maintain reserves with respect to
liabilities or assets consisting of or including Eurocurrency Liabilities,
additional interest on the unpaid principal amount of each Eurodollar Rate
Advance of such Bank to such Borrower, from the date of such Revolving Credit
Advance until such principal amount is paid in full, at an interest rate per
annum equal at all times to the remainder obtained by subtracting (a) the
Eurodollar Rate for the Interest Period for such Revolving Credit Advance from
(b) the rate obtained by dividing such Eurodollar Rate by a percentage equal to
100% minus the Eurodollar Rate Reserve Percentage of such Bank for such Interest
Period, payable on each date on which interest is payable on such Revolving
Credit Advance. Such additional interest shall be determined by such Bank and
notified to such Borrower through the Agent. A certificate as to the amount of
such additional interest submitted to such Borrower and the Agent by such Bank
shall be conclusive and binding for all purposes, absent manifest error. No Bank
shall have the right to recover any additional interest pursuant to this Section
2.17 for any period more than 90 days prior to the date such Bank notifies such
Borrower that additional interest may be charged pursuant to this Section 2.17.

Borrower pursuant to Section 3.2, such representation and warranty shall only be
made by such Borrower as provided in clause (v) of this Section 2.18, (v) with
respect to the representations and warranties made in Article IV or, if
applicable, any other Credit Document, each Borrower makes such representations
and warranties only with respect to, and only to the extent applicable to, such
Borrower and its Subsidiaries, and (vi) with respect to covenants set forth in
Article V, each Borrower is only responsible for compliance with such covenants
only with respect to, and only to the extent applicable to, such Borrower and

2004, filed with the Securities and Exchange Commission, and such Borrower's
quarterly report on Form 10-Q for the quarter ended March 31, 2005, filed with

     (h) No Borrower is engaged in the business of extending credit for the
purpose of purchasing or carrying margin stock (within the meaning of Regulation

as amended.

     (j) No Termination Event has occurred or is reasonably expected to occur
with respect to any Plan that could reasonably be expected to have a Material
Adverse Effect in respect of any Borrower. No Credit Party nor any Subsidiary or
ERISA Affiliate of any Credit Party has received any notification that any
Multiemployer Plan is in reorganization or has been terminated, within the
meaning of Title IV of ERISA that could reasonably be expected to have a

                                      -44-

company," or a "public utility" within the meaning of the Public Utility Holding
Company Act of 1935, as amended.

     (m) Except as set forth in a Borrower's annual report on Form 10-K for the

representations by the MLP only, as set forth in any of its filings with the
Securities and Exchange Commission, or as disclosed in writing by any Borrower
to the Banks and the Agent after the date hereof and approved in writing by the
Majority Banks, each Borrower and its Material Subsidiaries are in compliance
with all applicable Environmental Laws, except as could not reasonably be
expected to have a Material Adverse Effect in respect of such Borrower. Except
as disclosed in writing by any Borrower to the Banks and the Agent after the
date hereof and approved in writing by the Majority Banks, the aggregate
contingent and non-contingent liabilities of each Borrower and its Material
Subsidiaries (other than those reserved for in accordance with GAAP and
excluding liabilities to the extent covered by insurance if the insurer has
confirmed that such insurance covers such liabilities or which such Borrower
reasonably expects to recover from ratepayers) which to such Borrower's
knowledge are reasonably expected to arise in connection with (i) the
requirements of any Environmental Law or (ii) any obligation or liability to any
Person in connection with any Environmental matters (including any release or
threatened release (as such terms are defined in the Comprehensive Environmental
Response, Compensation and Liability Act of 1980) of any Hazardous Waste,
Hazardous Substance, other waste, petroleum or petroleum products into the
Environment) could not reasonably be expected to have a Material Adverse Effect
in respect of such Borrower. Each Borrower and its Material Subsidiaries holds,
or has submitted a good faith application for all Environmental Permits (none of
which have been terminated or denied) required for any of its current operations
or for any property owned, leased, or otherwise operated by it; and is, and
within the period of all applicable statutes of limitation has been, in
compliance with all of its Environmental Permits, except where the failure to
comply with the matters set forth in this sentence, in the aggregate, could not
reasonably be expected to have a Material Adverse Effect in respect of such
Borrower.

     (n) No Default or Event of Default has occurred and is continuing.

     (o) As of the date hereof, each Revolving Credit Facility Increase
Effective Date and each Letter of Credit Facility Increase Effective Date only,
after giving effect to the Credit Documents and each transaction thereunder
(including each Revolving Credit Advance and each Letter of Credit), each Credit
Party, individually and together with its Subsidiaries, is Solvent.

     (p) At all times prior to the Collateral Release Date, an Acceptable
Security Interest in all Collateral exists. Unless the Collateral Release Date
has occurred, Pipeline Holdco is the legal and beneficial owner of all
Collateral free and clear of any Lien other than Collateral Permitted Liens.

     (q) As of the date hereof only, none of the reports, financial statements,
certificates or other written information furnished by or on behalf of any
Borrower to the Agent or any Bank on or prior to the date hereof (as modified or
supplemented by other information so furnished on or prior to the date hereof),
taken as a whole, contains any material misstatement of fact or omits to state
any material fact necessary to make the statements therein, in the light of the
circumstances under which they were made, not materially misleading, provided
that, with respect to any projected financial information, the Borrowers
represent only that such information was prepared in good faith based upon
assumptions believed by the Borrowers to be reasonable at the time (it being
recognized, however, that projections as to future events are not to be viewed
as facts and that the actual results during the period or periods covered by any
projections may materially differ from the projected results). None of the
reports, financial statements, certificates or other written information
furnished by or on behalf of any Borrower to


                                      -45-

the Agent, any Issuing Bank or any Bank after the date hereof (as modified or
supplemented by other information so furnished after the date hereof), taken as
a whole, contains any material misstatement of fact or omits to state any
material fact necessary to make the statements therein, in the light of the
circumstances under which they were made, not materially misleading.

Subsidiaries to maintain, insurance with responsible and reputable insurance
companies or associations in such amounts and covering such risks as is usually

thereto, and on the terms set forth herein or therein, in favor of the
Collateral Agent, any of the Issuing Banks or any of the Banks, including the
execution, delivery, recordation and filing of any necessary documentation and
any deliveries of Collateral necessary to grant an Acceptable Security Interest
in all Collateral.

     (g) Inspection Rights. Permit, and cause each of its Material Subsidiaries
to permit, any representatives designated by the Agent, the Collateral Agent or

in good faith by appropriate proceedings, (b) such Borrower or such Material
Subsidiary has set aside on its books adequate reserves with respect thereto in

     SECTION 5.2. Negative Covenants. So long as any Revolving Credit Advance
shall remain unpaid, any Letter of Credit or Reimbursement Obligation shall
remain outstanding, any Letter of Credit Liability shall exist or any Issuing
Bank or any Bank shall have any Commitment hereunder, no Borrower will, without
the written consent of the Majority Banks (it being understood that each of the
permitted exceptions to each of the covenants in this Section 5.2 is in addition
to, and not overlapping with, any other of such permitted exceptions to such
covenant, except to the extent expressly provided therein):

     (a) Liens, Etc. Create, assume, incur or suffer to exist, or permit any of
its Material Subsidiaries to create, assume, incur or suffer to exist, any Lien
on or in respect of any of its property, whether now owned or hereafter
acquired, in each case to secure or provide for the payment of any Debt of
itself or any other Person (other than obligations or liabilities that are (1)
incurred, and are owed to trading counterparties, in the ordinary course of the
trading business of the Borrowers or any of their Subsidiaries (other than
Non-Recourse Subsidiaries and International Subsidiaries), and (2) secured only
by cash, short term investments or a Letter of Credit); provided, that,
notwithstanding the foregoing, the Borrowers or any of their Material
Subsidiaries may create, incur, assume or suffer to exist (i) General Permitted
Liens on assets that are not Collateral and (ii) Collateral Permitted Liens on
Collateral.

     (b) Debt.

          (i) In the case of TWC, permit the ratio of (A) the aggregate amount
of Consolidated Debt of TWC and its Consolidated Subsidiaries to (B) the sum of

Quarter of TWC ending after the Effective Date (x) on or before December 31,
2004, 0.75 to 1.00, (y) after December 31, 2004 and on or before December 31,
2005, 0.70 to 1.00 and (z) after December 31, 2005, 0.65 to 1.00;

          (ii) In the case of any Borrower (other than TWC and MLP), permit the
ratio of (A) the aggregate amount of Consolidated Debt of such Borrower and its
Consolidated Subsidiaries, to (B)


                                      -50-

the sum of the Consolidated Net Worth of such Borrower plus the aggregate amount
of Consolidated Debt of such Borrower and its Consolidated Subsidiaries to
exceed, on the last day of any Fiscal Quarter of such Borrower ending after the
Effective Date, 0.55 to 1.00;

          (iii) In the case of TWC, create, incur or assume, or permit any of
its Subsidiaries to create, incur or assume, any Debt at any time, if after
giving effect to such Debt, the ratio of (A) the aggregate amount of
Consolidated Debt of TWC and its Consolidated Subsidiaries to (B) the sum of the
Consolidated Net Worth of TWC as of the end of the Fiscal Quarter of TWC most
recently ended prior to such time for which the appropriate financial
information is available (adjusted, at TWC's option, to give effect, in
accordance with GAAP, to all material asset acquisitions and dispositions by TWC
and its Consolidated Subsidiaries since the end of such Fiscal Quarter) plus the
aggregate amount of Consolidated Debt of TWC and its Consolidated Subsidiaries
would exceed at such time (x) if such time is on or before December 31, 2004,
0.75 to 1.00, (y) if such time is after December 31, 2004 and on or before
December 31, 2005, 0.70 to 1.00 and (z) if such time is after December 31, 2005,
0.65 to 1.00; and

          (iv) In the case of any Borrower (other than TWC and MLP), create,
incur or assume, or permit any of its Subsidiaries to create, incur or assume,
any Debt at any time, if after giving effect to such Debt, the ratio of (A) the
aggregate amount of Consolidated Debt of such Borrower and its Consolidated
Subsidiaries to (B) the sum of the Consolidated Net Worth of such Borrower as of
the end of the Fiscal Quarter of such Borrower most recently ended prior to such
time for which the appropriate financial information is available (adjusted, at
such Borrower's option, to give effect, in accordance with GAAP, to all material
asset acquisitions and dispositions by such Borrower and its Consolidated
Subsidiaries since the end of such Fiscal Quarter) plus the aggregate amount of
Consolidated Debt of such Borrower and its Consolidated Subsidiaries would
exceed at such time 0.55 to 1.00.

     (c) EBITDA to Interest Expense Ratio. Permit, for any Measurement Period,
the ratio of (i) EBITDA to (ii) Interest Expense to be less than (A) 1.50 to
1.00, for any Measurement Period ending on or before March 31, 2005, (B) 2.00 to
1.00 for any Measurement Period ending after March 31, 2005 and on or before
December 31, 2005 or (C) 2.50 to 1.00 for any Measurement Period ending after
December 31, 2005. For avoidance of doubt, it is agreed that such ratio will be

assets, except that this Section 5.2(d) shall not prohibit any merger or
consolidation by any Borrower or by Pipeline Holdco with any Person that is not
a Credit Party, if such Borrower (or Pipeline Holdco, as the case may be, in a
merger or consolidation not involving a Borrower) is the surviving entity, so
long as all Liens on Collateral continue, prior to the Collateral Release Date,
as Acceptable Security Interests following any such transaction.

Subsidiary, (2) those encumbrances and restrictions existing on the Effective
Date, and other customary encumbrances and restrictions existing after the
Effective Date that are not more restrictive in any material respect, taken as a
whole, than the encumbrances and restrictions existing on the Effective Date
(provided that the application of any such restrictions and encumbrances to
additional Subsidiaries not


                                      -51-

subject thereto on the Effective Date shall not be deemed to make such

that restricts distributions by that Subsidiary pending its sale or other
disposition or (D) provisions with respect to distributions of assets or
property in joint venture agreements, asset sale agreements, stock sale
agreements and other similar agreements; provided that such encumbrances or
restrictions apply only to the assets or property subject to such joint venture,
asset sale, stock sale or similar agreement or to the assets or property being
sold, as the case may be, and (7) encumbrances or restrictions existing under or
by reason of Collateral Permitted Liens or General Permitted Liens securing debt
otherwise permitted to be incurred under this Section 5.2 that limit the right
of the debtor to dispose of the assets subject to such Collateral Permitted
Liens or General Permitted Liens.

Equity Interests in RMT to TWC or any Wholly-Owned Subsidiary of TWC if, but
only if, (x) there shall not exist or result a Default or Event of Default and
(y) in the case of each sale, transfer or other disposition referred to in this
proviso, such sale, transfer or other disposition could not reasonably be
expected to impair materially the ability of any Credit Party to perform its
obligations hereunder or under any other Credit Document and each Credit Party
shall continue to exist.

     (g) Compliance with ERISA. (i) Terminate, or permit any ERISA Affiliate of
such Borrower to terminate, any Plan so as to result in any material liability
of such Borrower, any Material Subsidiary of such Borrower or any such ERISA
Affiliate to the PBGC, if such material liability of such ERISA Affiliate could
reasonably be expected to have a Material Adverse Effect in respect of such
Borrower, or (ii) permit to occur any Termination Event with respect to a Plan
that would have a Material Adverse Effect in respect of such Borrower.

     (h) Transactions with Related Parties. Make any sale to, make any purchase
from, extend credit to, make payment for services rendered by, or enter into any
other transaction with, or permit any Material Subsidiary of such Borrower to
make any sale to, make any purchase from, extend credit to, make payment for
services rendered by, or enter into any other transaction with, any Related
Party of such Borrower or of such Material Subsidiary, unless as a whole such
sales, purchases, extensions of credit, rendition of services and other
transactions are (at the time such sale, purchase, extension of credit,
rendition of services or other transaction is entered into) on terms and
conditions reasonably fair in all material respects to such Borrower or such
Material Subsidiary in the good faith judgment of such Borrower (or, in the case
of the MLP, its conflicts committee or other relevant Person); provided that the
following items will not be deemed to be subject to the provisions of this
Section 5.2(h): (i) declaring or paying any dividend or distribution or
purchasing, redeeming, retiring, defeasing or otherwise acquiring for value any
Equity Interests, in each case not otherwise prohibited hereunder, (ii) any
agreement,


                                      -52-

instrument or arrangement as in effect on the Effective Date or any amendment
thereto or any transaction contemplated thereby (including pursuant to any
amendment thereto) in any replacement agreement thereto so long as any such
amendment or replacement agreement is not more disadvantageous to the Banks in
any material respect than the original agreement as in effect on the Effective
Date as determined in good faith by an Authorized Financial Officer of TWC,
(iii) (A) corporate sharing agreements among a Borrower and its Subsidiaries
with respect to tax sharing and general overhead and other administrative
matters and (B) any other intercompany arrangements disclosed or described in
TWC's report on Forms 10-K for the year ended December 31, 2003 and December 31,
2004 (including the exhibits attached to each), all as in effect on the
Effective Date or the date hereof, and any amendment or replacement of any of
the foregoing so long as such amendment or replacement agreement is not less
advantageous to any Borrower party thereto in any material respect than the
agreement so amended or replaced, as such agreement was in effect on the
Effective Date, or (iv) any sale to, purchase from, extension of credit to,
payment of services rendered by or any other transaction (I) between the MLP and
one or more Related Parties (other than a Credit Party), if such sale, purchase,
extension of credit, payment or transaction is made or completed in compliance
with the terms and provisions of the MLP Agreement, or (II) between the MLP and
one or more Credit Parties, if (a) such sale, purchase, extension of credit,
payment or transaction is made or completed in compliance with the terms and
provisions of the MLP Agreement, and (b) such sale, purchase, extension of
credit, payment or transaction is on terms and conditions reasonably fair in all
material respects to the other Credit Parties party thereto in the good faith
judgment of such other Credit Parties.

     (i) Grantors. In the case of TWC, permit, prior to the Collateral Release
Date, Pipeline Holdco:

          (i) To cause the withdrawal, application or transfer of any financial
assets or security entitlements with respect to the Collateral or give any
instructions or entitlement orders with respect to them;

          (ii) To move or establish its chief executive office in any place
different from its current location or change its state of incorporation or
organization without prior notice to the Collateral Agent; or

(iii) To establish a new location for its chief executive office or change its
name until it has given to the Collateral Agent not less than 10 days' prior
          written notice of its intention to do so, clearly describing such new
location
or specifying such new name or other name as the case may be, and providing such
other information in connection therewith as Collateral Agent may reasonably
request.

     (j) Use of Proceeds. Use any proceeds of any Revolving Credit Advance for
any purpose other than general corporate purposes relating to the business of a
Borrower and its Subsidiaries (including working capital, acquisitions and
capital expenditures), or use any such proceeds in any manner which violates or
results in a violation of law; provided that no proceeds of any Revolving Credit
Advance will be used in any manner which contravenes law, and no proceeds of any
Revolving Credit Advance will be used to purchase or carry any margin stock
(within the meaning of Regulation U).

     (k) Collateral Disposition. Sell, lease, transfer or otherwise dispose of,
or permit any of its Subsidiaries to sell, lease, transfer or otherwise dispose
of, any Collateral prior to the Collateral Release Date. For avoidance of doubt,
the foregoing sentence does not permit any disposition on or after the
Collateral Release Date of Equity Interests in TGPL to the extent otherwise
prohibited by Section 5.2(f).

     (l) Restricted Payments. (i) Declare or pay any dividends (other than in
common stock of such Borrower), purchase, redeem, retire, defease or otherwise
acquire for value any of its Equity


                                      -53-

Interests now or hereafter outstanding, return any capital to its stockholders,
partners or members (or the equivalent Persons thereof) as such, make any other
distribution of assets, Equity Interests, obligations or securities to its
stockholders, partners or members (or the equivalent Persons thereof) as such,
or permit Pipeline Holdco to do any of the foregoing, or (ii) permit any of its
Subsidiaries to purchase, redeem, retire, defease or otherwise acquire for value
any Equity Interests in any Borrower or Pipeline Holdco, unless no Event of
Default shall have occurred and be continuing at the time of any action
described in clauses (i) and (ii) above and no Event of Default would result
therefrom; provided, that, notwithstanding the foregoing, at any time, whether
or not an Event of Default exists, (1) TGPL and NWP shall be permitted to pay
dividends to Pipeline Holdco to permit Pipeline Holdco to (A) pay corporate
overhead expenses incurred in the ordinary course of business not to exceed
$2,000,000 in any fiscal year, (B) (and Pipeline Holdco shall be permitted to)
pay dividends to TWC to pay the corporate overhead and administration expenses
allocated (in a manner consistent with past practices) to Pipeline Holdco, TGPL,
NWP and their Subsidiaries, and (C) pay any taxes which are due and payable by
Pipeline Holdco, TGPL and NWP as part of a consolidated group and (2) MLP shall
be permitted to declare, make or incur liability to make distributions, on a
quarterly basis, of its Available Cash (as defined in the MLP Agreement) to its
unitholders and its general partner in accordance with the provisions of the MLP
Agreement.

     (m) Subsidiary Debt. Permit, prior to the Collateral Release Date, Pipeline
Holdco to create, incur, assume or suffer to exist any Debt, except (A) Debt in
an aggregate amount not to exceed $150,000,000 at any time outstanding, (B) Debt
owed to TWC or any of its Subsidiaries if all such Debt is evidenced by a
promissory note that is delivered to the Collateral Agent and in which an
Acceptable Security Interest exists and (C) the Pipeline Holdco Guaranty.

     (n) Non-Recourse Debt. Except in the case of MLP, create, incur or assume,
or permit any of its Subsidiaries to create, incur or assume, any Non-Recourse
Debt, unless, at the time of such creation, incurrence or assumption and
immediately after giving effect thereto, both (i) the aggregate principal amount
of all Non-Recourse Debt of all Subsidiaries of such Borrower does not exceed
10% of the total Consolidated assets of such Borrower and its Consolidated
Subsidiaries; and (ii) the aggregate principal amount of all Non-Recourse Debt
of all Subsidiaries of such Borrower that is secured by assets owned by such
Borrower or its Subsidiaries or by any of the other Borrowers or their
respective Subsidiaries (without duplication), on December 31, 2003 or by Equity
Interests in any Person that owns any such asset or that is otherwise supported
by such assets does not exceed 7.5% of the total Consolidated assets of such
Borrower and its Consolidated Subsidiaries, as shown on the respective balance
sheets of the Borrowers delivered pursuant to Section 4.1(e) of the 2004 Credit
Agreement.

                                   ARTICLE VI

                                EVENTS OF DEFAULT

Document to which it is a party within ten days after the same becomes due and
payable; or


                                      -54-

      (b) Any certification, representation or warranty (other than any Added

to have been incorrect in any material respect when made or deemed made; or

      (c) Any Credit Party shall fail to perform or observe (i) any term,
covenant or agreement contained in this Agreement (other than a term, covenant
or agreement contained in Section 5.2), any Note or any other Credit Document on
its part to be performed or observed and such failure shall continue for 30 days
after the earlier of the date notice thereof shall have been given to TWC by the
Agent or any Bank or the date an Authorized Officer of such Credit Party shall
have knowledge of such failure or (ii) any term, covenant or agreement contained
in Section 5.2; or

      (d) Any Borrower or any Subsidiary of any Borrower (other than a
Non-Recourse Subsidiary or an International Subsidiary) shall fail to pay any
principal of or premium or interest on any Debt which is outstanding in a
principal amount of at least $100,000,000 in the aggregate (excluding Debt
incurred pursuant to any Revolving Credit Advance) of such Borrower or any
Subsidiary of such Borrower (as the case may be) (other than a Non-Recourse
Subsidiary or an International Subsidiary), when the same becomes due and
payable (whether by scheduled maturity, required prepayment, acceleration,
demand or otherwise), and such failure shall continue after the applicable grace
period, if any, specified in the agreement or instrument relating to such Debt;
or any other event shall occur or condition shall exist under any agreement or
instrument relating to any such Debt and shall continue after the applicable
grace period, if any, specified in such agreement or instrument, if the effect
of such event or condition is to accelerate the maturity of such Debt; or any
such Debt shall be declared to be due and payable, or required to be prepaid
(other than (i) by a regularly scheduled required prepayment, (ii) as required
in connection with any permitted sale of assets, (iii) as required in connection
with any casualty or condemnation or (iv) as required pursuant to an illegality
event of the type set forth in Section 2.16), prior to the stated maturity
thereof; provided, however, that the provisions of this Section 6.1(d) shall not

Subsidiary or International Subsidiary; or

      (e) Any Borrower or any Material Subsidiary of any Borrower shall
generally not pay its debts as such debts become due, or shall admit in writing
its inability to pay its debts generally, or shall make a general assignment for
the benefit of creditors; or any proceeding shall be instituted by or against
any Borrower or any Material Subsidiary of any Borrower seeking to adjudicate it
a bankrupt or insolvent, or seeking liquidation, winding up, reorganization,
arrangement, adjustment, protection, relief, or composition of it or its debts
under any law relating to bankruptcy, insolvency or reorganization or relief of

of its property and, in the case of any such proceeding instituted against it
(but not instituted by it), shall remain undismissed or unstayed for a period of
60 days; or any Borrower or any Material Subsidiary of any Borrower shall take
any action to authorize any of the actions set forth above in this subsection
(e) (for the avoidance of doubt, Non-Recourse Subsidiaries and International
Subsidiaries are not subject to this clause (e)); or

      (f) One or more judgments or orders for the payment of money in excess of
$100,000,000 in the aggregate (to the extent not paid or to the extent not
covered by insurance or indemnities that TWC, in its reasonable good faith
judgment, believes will be paid when due by the parties providing such
indemnities or insurance) shall be rendered against any Borrower or any Material
Subsidiary of any Borrower and remain unsatisfied and either (i) enforcement
proceedings shall have been commenced by any creditor upon such judgment or
order or (ii) there shall be any period of 30 consecutive days during

                                      -55-

which a stay of enforcement of such judgment or order, by reason of a pending
appeal or otherwise, shall not be in effect (for the avoidance of doubt,
Non-Recourse Subsidiaries and International Subsidiaries are not subject to this
clause (f)); or

      (g) Any Termination Event with respect to a Plan shall have occurred and,
30 days after notice thereof shall have been given to any Borrower by the Agent,
(i) such Termination Event shall still exist and (ii) the sum (determined as of
the date of occurrence of such Termination Event) of the Insufficiency of such

definition herein of Termination Event shall have occurred and then exist, the
liability related thereto) is equal to or greater than $125,000,000; or

      (h) Any Credit Party or any Subsidiary or ERISA Affiliate of any Credit
Party shall have been notified by the sponsor of a Multiemployer Plan that it
has incurred Withdrawal Liability to such Multiemployer Plan in an amount which,
when aggregated with all other amounts required to be paid to Multiemployer
Plans in connection with Withdrawal Liabilities (determined as of the date of
such notification), exceeds $125,000,000 in the aggregate; or

      (i) Any Credit Party or any Subsidiary or ERISA Affiliate of any Credit
Party shall have been notified by the sponsor of a Multiemployer Plan that such
Multiemployer Plan is in reorganization or is being terminated, within the
meaning of Title IV of ERISA, if as a result of such reorganization or
termination the aggregate annual contributions of the Credit Parties and their
respective ERISA Affiliates to all Multiemployer Plans which are then in
reorganization or being terminated have been or will be increased over the
amounts contributed to such Multiemployer Plans for the respective plan years
which include the Effective Date by an amount exceeding $125,000,000; or

      (j) Prior to the Collateral Release Date, the Pledge or the Pipeline
Holdco Guaranty for any reason is not a legal, valid, binding and enforceable
obligation of Pipeline Holdco or any Credit Party shall so state in writing; or

      (k) Prior to the Collateral Release Date, any Collateral shall become
unavailable for use by its owner or title to any such Collateral shall be

      (l) The TWC Guaranty for any reason is not a legal, valid, binding and
enforceable obligation of TWC or any Credit Party shall so state in writing; or

      (m) A Change of Control Event shall occur;

then, and in any such event, the Agent while such event exists (i) shall at the
request, or may with the consent, of the Majority Banks, by notice to the
Borrowers, declare the Commitments of each Bank and of each Issuing Bank and the
obligations of each Issuing Bank to issue any Letter of Credit and each Bank to
make Revolving Credit Advances to be terminated, whereupon each Commitment and
each such obligation shall forthwith terminate, and (ii) shall at the request,
or may with the consent, of the Majority Banks, by notice to the Borrower as to
which an Event of Default exists, declare the principal of the Reimbursement
Obligations and Revolving Credit Advances owed by such Borrower, all interest
thereon and all other amounts payable by such Borrower under this Agreement and
any other Credit Document to be forthwith due and payable, whereupon all such
amounts shall become and be forthwith due and payable, without requirement of
any presentment, demand, protest, notice of intent to accelerate, further notice
of acceleration or other further notice of any kind (other than the notice
expressly provided for above), all of which are hereby expressly waived by the
Borrowers; provided, however, that in the event of any Event of Default
described in Section 6.1(e), (A) the Commitments of each Bank and of each

                                      -56-

Issuing Bank and the obligations of each Issuing Bank to issue a Letter of
Credit and each Bank to make Revolving Credit Advances shall automatically be
terminated and (B) the principal of the Reimbursement Obligations and Revolving
Credit Advances, all such interest and all such other amounts shall
automatically become and be due and payable, without presentment, demand,
protest, notice of intent to accelerate, notice of acceleration or any other
notice of any kind, all of which are hereby expressly waived by the Borrowers.
For purposes of this Section 6.1, any Reimbursement Obligation or Revolving
Credit Advances owed to an SPC shall be deemed to be owed to its Designating
Bank.

      SECTION 6.2. LC Cash Collateral Accounts. Upon the occurrence and during
the continuance of any Event of Default that exists as to any Borrower (if the
Agent has declared all amounts owed by such Borrower hereunder to be due and
payable), such Borrower agrees that it shall forthwith, without any demand or
the taking of any other action by any Issuing Bank, the Agent, or any of the
Banks, provide cover for the outstanding Letter of Credit Liabilities in respect
of Letters of Credit issued at the request of such Borrower by paying to the
Collateral Agent immediately available funds in the amount equal to the then
aggregate Available Amounts of all outstanding Letters of Credit issued at the
request of such Borrower, which funds shall be deposited into a blocked deposit
account or accounts to be established and maintained at the office of Citibank
(or an affiliate thereof) in the name of the Collateral Agent as collateral
security for any outstanding Letter of Credit Liabilities in respect of Letters
of Credit issued at the request of such Borrower (the "LC Cash Collateral
Accounts" in respect of such Borrower). Each Borrower hereby pledges, and grants
to the Collateral Agent for the ratable benefit of each Issuing Bank and the
Banks, a security interest in all funds held in the LC Cash Collateral Accounts
in respect of such Borrower from time to time and all proceeds thereof, as
security for the payment of all Letter of Credit Liabilities in respect of
Letters of Credit issued at the request of such Borrower. The Agent shall from
time to time direct the Collateral Agent to withdraw funds then held in the LC
Cash Collateral Accounts in respect of any Borrower and to deliver such funds to
the Agent to be applied first, to reimburse the Collateral Agent for all costs,
fees, expenses and other amounts to the extent provided in the relevant Credit
Document and, second, to the payment of any Reimbursement Obligations owing by
such Borrower to any Issuing Bank as shall have become or shall become due and
payable by such Borrower to such Issuing Bank under this Agreement in connection
with the Letters of Credit issued at the request of such Borrower. The
Collateral Agent shall exercise reasonable care in the custody and preservation
of any funds held in the LC Cash Collateral Accounts and shall be deemed to have
exercised such care if such funds are accorded treatment substantially
equivalent to that which the Collateral Agent accords its own property, it being
understood that the Collateral Agent shall not have any responsibility for
taking any necessary steps to preserve rights against any parties with respect
to any such funds or for investing such funds. If at any time (a) no Event of
Default exists and (b) the funds in the LC Cash Collateral Accounts in respect
of any Borrower deposited pursuant to this Section 6.2 exceed the aggregate
amount of all Letter of Credit Liabilities in respect of Letters of Credit
issued at the request of such Borrower, the Collateral Agent shall, upon request
of such Borrower, return such excess to such Borrower. LC Cash Collateral
Accounts may also be created as contemplated by Section 2.5(c) whether or not an
Event of Default exists.

                                   ARTICLE VII

               THE AGENT; THE COLLATERAL AGENT; AND ISSUING BANKS

      SECTION 7.1. Agent's and Collateral Agent's Authorization and Action. Each
of the Banks and Issuing Banks hereby appoints and authorizes the Agent and the
Collateral Agent to take such action respectively as agent and collateral agent
on its behalf and to exercise such powers under this Agreement and the other
Credit Documents as are delegated respectively to the Agent and to the
Collateral Agent by the terms hereof and thereof, together with such powers as
are reasonably incidental thereto. As to any matters not expressly provided for
by the Credit Documents (including enforcement of the terms of this

                                      -57-

Agreement or collection of the Reimbursement Obligations or Notes, fees and any
other amounts due and payable pursuant to this Agreement), neither the Agent nor
the Collateral Agent shall be required to exercise any discretion or take any
action, but shall be required to act or to refrain from acting (and shall be
fully protected in so acting or refraining from acting) upon the instructions of
the Majority Banks, and such instructions shall be binding upon all Banks and
all holders of Notes; provided, however, that neither the Agent nor the
Collateral Agent shall be required to take any action which exposes the Agent or
the Collateral Agent to personal liability or which is contrary to the Credit
Documents or applicable law. The Agent and the Collateral Agent agree to give to
each Bank prompt notice of each notice given to it by any Borrower pursuant to
the terms of this Agreement or any other Credit Document. The Agent will
promptly furnish to each Bank all items furnished to the Agent pursuant to
Section 5.1(b).

      SECTION 7.2. Agent's and Collateral Agent's Reliance, Etc. Neither the
Agent nor the Collateral Agent nor any of their respective directors, officers,
agents or employees shall be liable for any action taken or omitted to be taken
by them or under or in connection with this Agreement, except for its or their
own gross negligence or willful misconduct. Without limitation of the generality
of the foregoing, the Agent and the Collateral Agent: (i) may consult with legal
counsel (including counsel for any Borrower), independent public accountants and
other experts selected by them and shall not be liable for any action taken or
omitted to be taken in good faith by them in accordance with the advice of such
counsel, accountants or experts; (ii) make no warranty or representation to any
Bank or Issuing Bank and shall not be responsible to any Bank of Issuing Bank
for any statements, warranties or representations (whether written or oral) made
in or in connection with this Agreement or any other Credit Document; (iii)
shall not have any duty to ascertain or to inquire as to the satisfaction,
performance or observance of any of the terms, covenants or conditions of this
Agreement or any other Credit Document on the part of any Credit Party or to
inspect the property (including the books and records) of any Credit Party; (iv)
shall not be responsible to any Bank or Issuing Bank for the perfection,
priority, existence, sufficiency or value of any Collateral, other security,
guaranty or insurance or for the due execution, legality, validity,
enforceability, genuineness, sufficiency or value of this Agreement, any other
Credit Document or any other instrument or document furnished pursuant hereto or
thereto; (v) shall incur no liability under or in respect of any Credit Document
by acting upon any notice, consent, certificate or other instrument or writing
(which may be by telecopier, telegram, cable, telex or otherwise) believed by
either of them in its reasonable judgment to be genuine and signed or sent by
the proper party or parties; (vi) may treat any Issuing Bank that issues or has
issued a Letter of Credit as being the issuer of such Letter of Credit for all
purposes and (vii) may treat a Bank as the obligee of any Revolving Credit
Advance or, if applicable, the payee of any Note as the holder thereof, until
the Agent receives and accepts a Transfer Agreement executed by a Borrower (if
required pursuant to Section 8.5), the assignor Bank and the assigning Bank
pursuant to Section 8.5. Without limiting the generality of the foregoing,
insofar as the Agent is concerned, for purposes of determining compliance with
any Credit Document (including Section 3.2 of this Agreement) with respect to
any Revolving Credit Advance, each Bank shall be deemed to have consented to,
approved and accepted and to be satisfied with each matter required under any
Credit Document (including Section 3.2 of this Agreement), unless the officer of
the Agent responsible for the transactions contemplated by the Credit Documents
shall have received written notice from such Bank prior to such Revolving Credit
Advance specifying its objection thereto and such Bank shall not have made
available to the Agent any portion of such Revolving Credit Advance; provided
that this sentence is solely for the benefit of the Agent (and not any Credit
Party) and shall not amend, waive or otherwise modify Section 3.2, Section
6.1(b) or any other provision applicable to any Credit Party, whether in respect
of such Revolving Credit Advance or any other Revolving Credit Advance or
matter.

      SECTION 7.3. Issuing Banks' Reliance, Etc. Neither the Issuing Banks nor
any directors, officers, agents or employees of the Issuing Banks shall be
liable for any action taken or omitted to be taken by any of them under or in
connection with this Agreement, except for its or their own gross negligence or
willful misconduct. The Issuing Banks shall not have, by reason of this
Agreement a

                                      -58-

fiduciary relationship in respect of any Bank; and nothing in this Agreement,
expressed or implied, is intended or shall be so construed as to impose upon the
Issuing Banks any obligations in respect of this Agreement except as expressly
set forth herein. Without limitation of the generality of the foregoing, the
Issuing Banks: (i) may consult with legal counsel (including counsel for any
Borrower), independent public accountants and other experts selected by it and
shall not be liable for any action taken or omitted to be taken in good faith by
it in accordance with the advice of such counsel, accountants or experts; (ii)
make no warranty or representation to any Bank or Issuing Bank and shall not be
responsible to any Bank or Issuing Bank for any statements, warranties or
representations (whether written or oral) made in or in connection with this
Agreement or any other Credit Document; (iii) shall not have any duty to
ascertain or to inquire as to the satisfaction, performance or observance of any
of the terms, covenants or conditions of this Agreement or any other Credit
Document on the part of any Credit Party or to inspect the property (including
the books and records) of any Credit Party; (iv) shall not be responsible to any
Bank or Issuing Bank for the perfection, priority, existence, sufficiency or
value of any Collateral, other security, guaranty or insurance or for the due
execution, legality, validity, enforceability, genuineness, sufficiency or value
of this Agreement or any other Credit Document or any other instrument or
document furnished pursuant hereto or thereto; and (v) shall incur no liability
under or in respect of any Credit Document by acting upon any notice, consent,
certificate or other instrument or writing (which may be by telecopier,
telegram, cable, telex or otherwise) believed by any of them in its reasonable
judgment to be genuine and signed or sent by the proper party or parties.
Without limiting the generality of the foregoing, insofar as each Issuing Bank
is concerned, for purposes of determining compliance with any Credit Document
(including Section 3.2 of this Agreement) with respect to any issuance or
increase of any Letter of Credit, each Bank shall be deemed to have consented
to, approved and accepted and to be satisfied with each matter required under
any Credit Document (including Section 3.2 of this Agreement), unless the
officer of such Issuing Bank responsible for the transactions contemplated by
the Credit Documents shall have received written notice from such Bank prior to
such issuance or increase specifying its objection thereto and such Bank shall
not have accepted after such issuance or increase any Letter of Credit Fee
associated with such increase or, in the case of an issuance of any Letter of
Credit, associated with such Letter of Credit; provided that this sentence is
solely for the benefit of the Issuing Banks (and not any Credit Party) and shall
not amend, waive or otherwise modify Section 3.2, Section 6.1(b) or any other
provision applicable to any Credit Party, whether in respect of such Letter of
Credit or any other Letter of Credit or matter.

      SECTION 7.4. Rights. With respect to its Commitments, the Revolving Credit
Advances made by it and the Notes, if any, issued to it, or any Letter of Credit
Interest held by it, CUSA shall have the same rights and powers under any such
Note and the other Credit Documents as any other Bank and may exercise the same
as though it was not the Agent and Collateral Agent. With respect to its Letter
of Credit Commitments, the Reimbursement Obligations owed to it or any Letter of
Credit Interest held by it, the Issuing Banks shall have the same rights and
powers under this Agreement as any other Bank and may exercise the same as
though it was not an Issuing Bank, as the case may be. CUSA, each Issuing Bank
and the respective affiliates of each may accept deposits from, lend money to,
act as trustee under indentures of, and generally engage in any kind of business
with, any Borrower, any Person who may do business with or own, directly or
indirectly, securities of any Borrower and any other Person, all as if CUSA were
not the Agent and Collateral Agent and each Issuing Bank was not an Issuing
Bank, in each case without any duty to account therefor to the Banks or the
Issuing Banks.

      SECTION 7.5. Indemnification. (a) The Banks agree to indemnify the Agent
and the Collateral Agent (to the extent not reimbursed by the Borrowers),
ratably according to the respective Letter of Credit Interests then held by each
of the Banks plus the respective principal amounts of the Revolving Credit
Advances owed to each of them (or if no Letter of Credit Interests or Revolving
Credit Advances are at the time outstanding, ratably according to their
respective Revolving Credit Commitments for TWC (or, if such Commitments have
terminated, their respective Revolving Credit Commitments for TWC immediately
prior to such termination)), from and against any and all claims, damages,
losses, liabilities,

                                      -59-

costs, fees and expenses (including reasonable fees and disbursements of
external counsel) of any kind or nature whatsoever which may be imposed on,
incurred by, or asserted against either the Agent or the Collateral Agent in any
way relating to or arising out of this Agreement or any other Credit Document or
any action taken or omitted by the Agent or the Collateral Agent under this
Agreement or any other Credit Document, including any of the foregoing incurred
in connection with any action taken under Section 5.1(g) (EXPRESSLY INCLUDING
ANY SUCH CLAIM, DAMAGE, LOSS, LIABILITY, COST, FEE OR EXPENSE ATTRIBUTABLE TO
THE ORDINARY, SOLE OR CONTRIBUTORY NEGLIGENCE OF THE AGENT OR THE COLLATERAL
AGENT, BUT EXCLUDING ANY SUCH CLAIM, DAMAGE, LOSS, LIABILITY, COST, FEE OR
EXPENSE ATTRIBUTABLE TO THE GROSS NEGLIGENCE OR WILLFUL MISCONDUCT OF THE AGENT
AND THE COLLATERAL AGENT). IT IS THE INTENT OF THE PARTIES HERETO THAT EACH OF
THE AGENT AND THE COLLATERAL AGENT SHALL, TO THE EXTENT PROVIDED IN THIS SECTION
7.5, BE INDEMNIFIED FOR ITS OWN ORDINARY, SOLE OR CONTRIBUTORY NEGLIGENCE.
Without limitation of the foregoing, each Bank agrees to reimburse the Agent and
the Collateral Agent promptly upon demand for their respective ratable shares of
any out-of-pocket expenses (including external counsel fees) incurred
respectively by the Agent or the Collateral Agent in connection with the
preparation, execution, delivery, administration, modification, amendment or
enforcement (whether through negotiations, legal proceedings or otherwise) of,
or legal advice in respect of rights or responsibilities under, this Agreement
or any other Credit Document to the extent that the Agent and the Collateral
Agent are not reimbursed for such expenses by the Borrowers.

      (b) The Banks agree to indemnify each Issuing Bank (to the extent not
reimbursed by the Borrowers), ratably according to the respective Letter of
Credit Interests then held by each of the Banks plus the respective principal
amounts of the Revolving Credit Advances owed to each of them (or if no Letter
of Credit Interests or Revolving Credit Advances are at the time outstanding,
ratably according to their respective Revolving Credit Commitments for TWC (or,
if such Commitments have terminated, their respective Revolving Credit
Commitments for TWC immediately prior to such termination)), from and against
any and all claims, damages, losses, liabilities, costs, fees and expenses
(including reasonable fees and disbursements of external counsel) of any kind or
nature whatsoever which may be imposed on, incurred by, or asserted against any
Issuing Bank in any way relating to or arising out of this Agreement or any
other Credit Document or any action taken or omitted by any Issuing Bank under
this Agreement or any other Credit Document (EXPRESSLY INCLUDING ANY SUCH CLAIM,
DAMAGE, LOSS, LIABILITY, COST, FEE OR EXPENSE ATTRIBUTABLE TO THE ORDINARY, SOLE
OR CONTRIBUTORY NEGLIGENCE OF ANY ISSUING BANK, BUT EXCLUDING ANY SUCH CLAIM,
DAMAGE, LOSS, LIABILITY, COST, FEE OR EXPENSE ATTRIBUTABLE TO THE GROSS
NEGLIGENCE OR WILLFUL MISCONDUCT OF SUCH ISSUING BANK). IT IS THE INTENT OF THE
PARTIES HERETO THAT AN ISSUING BANK SHALL, TO THE EXTENT PROVIDED IN THIS
SECTION 7.5, BE INDEMNIFIED FOR ITS OWN ORDINARY, SOLE OR CONTRIBUTORY
NEGLIGENCE. Without limitation of the foregoing, each Bank agrees to reimburse
each Issuing Bank promptly upon demand for its ratable share of any
out-of-pocket expenses (including external counsel fees) incurred by such
Issuing Bank in connection with the preparation, execution, delivery,
administration, modification, amendment or enforcement (whether through
negotiations, legal proceedings or otherwise) of, or legal advice in respect of
rights or responsibilities under, this Agreement or any other Credit Document to
the extent that such Issuing Bank is not reimbursed for such expenses by the
Borrowers.

      SECTION 7.6. Successor Agent and Collateral Agent. The Agent and
Collateral Agent may resign at any time respectively as Agent and Collateral
Agent under this Agreement by giving written notice thereof to the Banks and the
Borrowers and may be removed at any time with or without cause by the Majority
Banks; provided, however that any removal of the Agent will not be effective
until it has also been replaced as Collateral Agent. Upon any such resignation
or removal, the Majority Banks shall

                                      -60-

have the right to appoint, with the consent of the Borrowers (which consent
shall not be unreasonably withheld and shall not be required if an Event of
Default under Section 6.1(a) or 6.1(e) exists), a successor Agent and Collateral
Agent from among the Banks. If no successor Agent and Collateral Agent shall
have been so appointed by the Majority Banks with such consent, and shall have
accepted such appointment, within 30 days after the respective retiring Agent's
or Collateral Agent's giving of notice of resignation or the Majority Banks'
removal of the retiring Agent or Collateral Agent, then the retiring Agent or
Collateral Agent may, on behalf of the Banks, appoint respectively a successor
Agent or Collateral Agent, which shall be a Bank which is a commercial bank
organized under the laws of the United States of America or of any State thereof
and having a combined capital and surplus of at least $500,000,000. Upon the
acceptance of any appointment as Agent or Collateral Agent under this Agreement
by respectively a successor Agent or Collateral Agent, such successor Agent or
Collateral Agent shall thereupon succeed to and become vested with all the
rights, powers, privileges and duties of the retiring Agent or Collateral Agent
and shall function as the Agent or Collateral Agent under this Agreement, and
the retiring Agent or Collateral Agent shall be discharged from its duties and
obligations as Agent or Collateral Agent under this Agreement. After any
retiring Agent's or Collateral Agent's resignation or removal hereunder
respectively as Agent or Collateral Agent, the provisions of this Article VII
shall inure to its benefit as to any actions taken or omitted to be taken by it
while it was Agent or Collateral Agent under this Agreement.

      SECTION 7.7. Bank Decisions. Each of the Agent, the Collateral Agent, the
Banks and the Issuing Banks acknowledges that it has, independently and without
reliance upon the Collateral Agent, the Agent, the Syndication Agent, the Joint
Lead Arrangers, the Issuing Banks or any other Bank and based on the financial
statements referred to in Section 4.1(e) and such other documents and
information as it has deemed appropriate, made its own credit analysis and its
own decision to enter into this Agreement. Each of the Agent, the Collateral
Agent, the Banks and the Issuing Banks (in each case, both on its own behalf and
on behalf of its affiliates, directors, officers, employees and agents that are
Indemnified Parties) also acknowledges that it will, independently and without
reliance upon the Collateral Agent, the Agent, the Syndication Agent, the Joint
Lead Arrangers, the Issuing Banks or any other Bank and based on such documents
and information as it shall deem appropriate at the time, continue to make its
own decisions in taking or not taking action under this Agreement and the other
Credit Documents. The Collateral Agent shall not have any duty or
responsibility, either initially or on a continuing basis, to provide any Person
with any credit or other information, whether coming into its possession before
the issuance of any Letter of Credit or making of any Revolving Credit Advance
or at any time or times thereafter.

      SECTION 7.8. Certain Rights of the Collateral Agent. If the Collateral
Agent shall request instructions from the Majority Banks with respect to any act
or action (including failure to act) in connection with this Agreement or any
other Credit Document, the Collateral Agent shall be entitled to refrain from
such act or taking such action unless and until the Collateral Agent shall have
received instructions from the Majority Banks; and it shall not incur liability
to any Person by reason of so refraining. Without limiting the foregoing, no
Bank nor any Issuing Bank nor the Agent nor any Indemnified Party shall have any
right of action whatsoever against the Collateral Agent as a result of its
acting or refraining from acting hereunder or under any other Credit Document in
accordance with the instructions of the Majority Banks. Furthermore, except for
action expressly required of the Collateral Agent hereunder, the Collateral
Agent shall in all cases be fully justified in failing or refusing to act
hereunder unless it shall be specifically indemnified to its satisfaction by the
Banks against any and all liability and expense which may be incurred by it by
reason of taking or continuing to take any such action.

      SECTION 7.9. Other Agents. The Syndication Agent, the Co-Documentation
Agents and the Joint Lead Arrangers have no duties or obligations under any
Credit Document. None of the Syndication

                                      -61-

Agent, the Co-Documentation Agents or the Joint Lead Arrangers shall have, by
reason of this Agreement or the other Credit Documents, a fiduciary relationship
in respect of any Bank or any Issuing Bank, and nothing in this Agreement or
other Credit Documents, express or implied, is intended or shall be so construed
to impose on any of the Syndication Agent, the Co-Documentation Agents or the
Joint Lead Arrangers any obligation in respect of this Agreement or other Credit
Documents.

                                  ARTICLE VIII

                                  MISCELLANEOUS

      SECTION 8.1. Amendments, Etc. No amendment or waiver of any provision of
this Agreement, nor consent to any departure by any Borrower therefrom, shall in
any event be effective unless the same shall be in writing and signed by the
Majority Banks and the Borrowers, and then such waiver or consent shall be
effective only in the specific instance and for the specific purpose for which
given; provided, however, that no amendment, waiver or consent shall, unless in
writing and signed by all the Banks directly affected thereby (it being

addition to the Banks required above to take such action, affect the rights or
duties of the Agent under any Credit Document; and provided further that no
amendment, waiver or consent shall, unless in writing and signed by each Issuing
Bank in addition to the Banks required above to take such action, affect the

action, affect the rights or duties of the Collateral Agent under any Credit
Document.

THE PLATFORM IS PROVIDED "AS IS" AND "AS AVAILABLE". THE AGENT PARTIES (AS
DEFINED BELOW) DO NOT WARRANT THE ACCURACY OR COMPLETENESS OF THE
COMMUNICATIONS, OR THE ADEQUACY OF THE PLATFORM AND EXPRESSLY DISCLAIM LIABILITY
FOR ERRORS OR OMISSIONS IN THE COMMUNICATIONS. NO WARRANTY OF ANY KIND, EXPRESS,

LIABILITY TO ANY BORROWER, ANY BANK, ANY ISSUING BANK OR ANY OTHER PERSON OR
ENTITY FOR DAMAGES OF ANY KIND, INCLUDING DIRECT OR INDIRECT, SPECIAL,

held by such Bank, its Letter of Credit Interest and any or all of its Revolving
Credit Commitments); provided, that (i) each such assignment shall be of a
constant, and not a varying, percentage of all rights and obligations under this
Agreement and the Notes, (ii) except in the case of an assignment of all of a
Bank's rights and obligations under this Agreement or an assignment to another
Bank, the amount of the Revolving Credit Commitment for TWC of the assigning
Bank being assigned pursuant to each such assignment (determined as of the date
of the Transfer Agreement with respect to such assignment) shall be in an
aggregate amount of $5,000,000 (or such lesser amount as may be consented to by
the Agent and the Borrowers) and in an integral multiple of $1,000,000 (unless
otherwise consented to by the Agent and the Borrowers), (iii) each such
assignment shall be to an Eligible Assignee, (iv) the parties to each such
assignment shall execute and deliver to the Agent, for its acceptance and
recording in the Register maintained by the Agent, a Transfer Agreement and a
processing and recordation fee of $3,500 (which fee shall be paid by such
Eligible Assignee or, in the case of Transfer Agreements referred to in Section
2.19(c), TWC) and (v) each such assignment of any Revolving Credit Commitment
for any Borrower shall be made only if the same percentage of the Revolving
Credit Commitments of such assigning Bank for each of the other Borrowers and
the same percentage of the LC Participation Percentage of the assigning Bank are
simultaneously assigned by the assigning Bank to the same Eligible Assignee
pursuant to the same Transfer Agreement. Upon such execution, delivery,
acceptance and recording, from and after the effective date specified in each
Transfer Agreement, (x) the assignee thereunder shall be a party hereto as a
"Bank" and, to the extent that rights and obligations hereunder have been
assigned to it pursuant to such Transfer Agreement, have the rights and
obligations of a Bank hereunder (including obligations to the Issuing Banks, the
Agent and the Collateral Agent pursuant to Section 7.5) and (y) the Bank
assignor thereunder shall, to the extent that rights and obligations hereunder
have been assigned by it pursuant to such Transfer Agreement, relinquish its
rights and be released from its obligations under this Agreement, except for
rights and obligations which continue after repayment of the Reimbursement
Obligations and Revolving Credit Advances or termination of this Agreement
pursuant to the express terms of this Agreement (and, in the case of a Transfer
Agreement covering all of an assigning Bank's rights and obligations under this
Agreement, such Bank shall cease to be a party hereto, except as to such rights
and obligations).

      (b) By executing and delivering a Transfer Agreement, the Bank assignor
thereunder and the assignee thereunder confirm to and agree with each other and
the other parties hereto as follows: (i) other than as provided in such Transfer
Agreement, such assignor makes no representation or warranty and assumes no
responsibility with respect to any statements, warranties or representations
(whether written or oral) made in or in connection with this Agreement, any
other Credit Document or any other instrument or document furnished pursuant
hereto or in connection herewith, the perfection, priority, existence,
sufficiency or value of any Collateral, other security, guaranty or insurance or
the execution, legality, validity, enforceability, genuineness, sufficiency or
value of any Credit Document or any other instrument or document furnished
pursuant hereto or in connection herewith, (ii) such assignor makes no
representation or warranty and assumes no responsibility with respect to the
financial condition of any



                                      -66-

Borrower or any other Person or the performance or observance by any Borrower or
any other Person of any of its respective obligations under the Credit Documents
or any other instrument or document furnished pursuant hereto or in connection
herewith; (iii) such assignee confirms that it has received a copy of this
Agreement, together with copies of such financial statements and such other
documents and information as it has deemed appropriate to make its own credit
analysis and its own decision to enter into such Transfer Agreement; (iv) such
assignee will, independently and without reliance upon the Agent, the Collateral
Agent, any Issuing Bank, such assignor or any other Bank and based on such
financial statements and such other documents and information as it shall deem
appropriate at the time, continue to make its own credit analysis and its own
decisions in taking or not taking action under this Agreement, any of the other
Credit Documents or any other instrument or document; (v) such assignee confirms
that it is an Eligible Assignee; (vi) such assignee appoints and authorizes the
Agent and the Collateral Agent, respectively, to act as Agent and Collateral
Agent, respectively, on its behalf and to exercise such powers and discretion
under this Agreement, any other Credit Document or any other document executed
in connection herewith or therewith as are delegated to the Agent and the
Collateral Agent, respectively, by the terms hereof or thereof, together with
such powers and discretion as are reasonably incidental thereto; and (vii) such
assignee agrees that it will perform in accordance with their terms all of the
obligations which by the terms of this Agreement are required to be performed by
it as a Bank.

      (c) The Agent shall maintain a copy of each Transfer Agreement, Revolving
Credit Commitment Increase Agreement and Letter of Credit Commitment Increase
Agreement, delivered to and accepted by it and a register for the recordation of
the names and addresses of each Bank and each Issuing Bank together with its
respective Revolving Credit Commitment for each Borrower, Letter of Credit
Commitment, LC Participation Percentage, Letter of Credit Interest and the
principal amount of the Revolving Credit Advances owing to each Bank by each
Borrower from time to time (the "Register"). The entries in the Register made
pursuant to this Section 8.5(c) shall be conclusive and binding for all
purposes, absent manifest error, and the Borrowers, the Agent, the Issuing Banks
and the Banks may treat each Person whose name is recorded in the Register as a
Bank or Issuing Bank, as the case may be, hereunder for all purposes of this
Agreement. The Register shall be available for inspection by any Borrower, any
Issuing Bank or any Bank at any reasonable time and from time to time upon
reasonable prior notice.

      (d) Upon its receipt of a Transfer Agreement executed and completed by an
assigning Bank and an assignee representing that it is an Eligible Assignee (and
consented to by the Agent, the Issuing Banks and, if required, by TWC), the
Agent shall (i) accept such Transfer Agreement, (ii) record the information
contained therein in the Register and (iii) give prompt notice thereof to the
Borrowers. If requested by the assigning or assignee Bank, each Borrower after
its receipt of such notice, shall, at its own expense, execute and deliver to
the Agent, any Notes requested pursuant to Section 2.10(a) (with any Notes being
replaced thereby being promptly returned to such Borrower by the holder
thereof). Such new Notes shall be dated the effective date of such Transfer
Agreement and shall otherwise be in substantially the form of Exhibit G hereto.

      (e) Each Bank or Issuing Bank may sell participations to one or more banks
or other entities (other than the Borrowers or any of their Affiliates) in or to
all or a portion of its rights and obligations under this Agreement (including
all or a portion of its Commitment, the Revolving Credit Advances owing to it,
the Notes held by it and its Letter of Credit Interest); provided, that (i) such
Bank's or Issuing Bank's, as the case may be, obligations under this Agreement
shall remain unchanged, (ii) such Bank or Issuing Bank, as the case may be,
shall remain solely responsible to the other parties hereto for the performance
of such obligations, (iii) such Bank shall remain the holder of any such Note
for all purposes of this Agreement, (iv) the Borrowers, the Agent, the
Collateral Agent, each other Issuing Bank and the other Banks shall continue to
deal solely and directly with such Bank or Issuing Bank, as the case may be, in
connection with such Bank's or Issuing Bank's, as the case may be, rights and
obligations under this



                                      -67-

Agreement, (v) all amounts payable under this Agreement shall be calculated as
if such Bank or Issuing Bank, as the case may be, had not sold such
participation, and (vi) the terms of any such participation shall not restrict
such Bank's or Issuing Bank's, as the case may be, ability to consent to any
departure by any Borrower herefrom without the approval of the participant,
except that the approval of the participant may be required to the extent that
such amendment, waiver or consent would reduce the principal of, or interest on,
the Reimbursement Obligations or Revolving Credit Advances or any fees or other
amounts payable hereunder, in each case to the extent subject to such
participation, or postpone any date fixed for any payment of principal of, or
interest on, the Reimbursement Obligations or Revolving Credit Advances or any
fees or other amounts payable hereunder, in each case to the extent subject to
such participation.

      (f) Notwithstanding any other provisions set forth in this Agreement, any
Bank or Issuing Bank may at any time create a security interest in all or any
portion of its rights under this Agreement (including its Letter of Credit
Interest) or any of its Notes in favor of any Federal Reserve Bank in accordance
with Regulation A of the Federal Reserve Board without notice to or consent of
the Borrowers, the Issuing Banks or the Agent. Furthermore, any Bank or Issuing
Bank may assign, as collateral or otherwise, any of its rights (including rights
to payments of principal of and/or interest on its Letter of Credit Interest or
Revolving Credit Advances made by such Bank) under this Agreement, its Notes or
any of its Letter of Credit Interest to any Federal Reserve Bank without notice
to or consent of any Borrower, the Issuing Banks or the Agent.

      (g) Notwithstanding anything to the contrary contained herein, any Bank or
Issuing Bank (a "Designating Bank") with the consent of the Agent (and, if no
Event of Default has occurred and is continuing, the Borrowers) may grant to a
special purpose funding vehicle (an "SPC"), identified as such in writing from
time to time by the Designating Bank to the Agent and the Borrowers, the option
to fund all or any part of any payment to any Issuing Bank or Revolving Credit
Advance which the Designating Bank has agreed to make; provided that no
Designating Bank shall have granted at any one time such option to more than one
SPC; and provided further that (i) such Designating Bank's obligations under
this Agreement shall remain unchanged, (ii) such Designating Bank shall remain
solely responsible to the other parties hereto for the performance of such
obligations, (iii) the Borrowers, the Issuing Banks, the Collateral Agent, the
Agent and the other Banks shall continue to deal solely and directly with such
Designating Bank in connection with such Designating Bank's rights and
obligations under this Agreement, (iv) any such option granted to an SPC shall
not constitute a commitment by such SPC to fund any drawing under a Letter of
Credit or to fund any Revolving Credit Advance, and (v) neither the grant nor
the exercise of such option to an SPC shall increase the costs or expenses or
otherwise increase or change the obligations of a Borrower under this Agreement
(including its obligations under Section 2.6). The issuance of a Letter of
Credit or the making of a Revolving Credit Advance by an SPC hereunder shall
utilize the Commitment of the Designating Bank to the same extent, and as if,
such Revolving Credit Advance were made by or such Letter of Credit were issued
by such Designating Bank. Each party hereto hereby agrees that no SPC shall be
liable for any indemnity or similar payment obligation under this Agreement to
the extent that any such indemnity or similar payment obligations shall have
been paid by its Designating Bank. In furtherance of the foregoing, each party
hereto hereby agrees (which agreement shall survive the termination of this
Agreement) that, prior to the date that is one year and one day after the
payment in full of all outstanding commercial paper or other senior indebtedness
of any SPC, it will not institute against, or join any other person in
instituting against such SPC any bankruptcy, reorganization, arrangement,
insolvency or liquidation proceedings under the laws of the United States. In
addition, notwithstanding anything to the contrary contained in this Section
8.5, an SPC may not assign its interest in any Letter of Credit Interests or
Revolving Credit Advance except that, with notice to, but without the prior
written consent of, the Borrowers and the Agent and without paying any
processing fee therefor, such SPC may assign all or a portion of its interests
in any Letter of Credit Interests or Revolving Credit Advance to the Designating
Bank or to any financial institutions



                                      -68-

(consented to by the Borrowers, Issuing Banks and Agent), providing liquidity
and/or credit support to or for the account of such SPC to support the funding
or maintenance of Letter of Credit Interests or Revolving Credit Advance. Each
Designating Bank shall serve as the agent of its SPC and shall on behalf of its
SPC: (i) receive any and all payments made for the benefit of such SPC and (ii)
give and receive all communications and notices, and vote, approve or consent
hereunder, and take all actions hereunder, including votes, approvals, waivers,
consents and amendments under or relating to this Agreement, the Notes and the
other Credit Documents. Any such notice, communication, vote, approval, waiver,
consent or amendment shall be signed by the Designating Bank for the SPC and
need not be signed by such SPC on its own behalf. The Borrowers, the Issuing
Banks, the Collateral Agent, the Agent and the Banks may rely thereon without
any requirement that the SPC sign or acknowledge the same or that notice be
delivered to the Borrowers or the SPC. This Section 8.5(g) may not be amended
without the written consent of any SPC, which shall have been identified to the
Agent and the Borrowers.

      SECTION 8.6. Governing Law. This Agreement and the Notes shall be governed
by, and construed in accordance with, the laws of the State of New York.

      SECTION 8.7. Interest. It is the intention of the parties hereto that the
Agent, each Issuing Bank, the Collateral Agent and each Bank shall conform
strictly to usury laws applicable to it, if any. Accordingly, if the
transactions with the Agent, any Issuing Bank, the Collateral Agent or any Bank
contemplated hereby would be usurious under applicable law, then, in that event,
notwithstanding anything to the contrary in this Agreement, any Credit Document
or any other agreement entered into in connection with or as security for this
Agreement or any other Credit Document, it is agreed as follows: (i) the
aggregate of all consideration which constitutes interest under applicable law
that is contracted for, taken, reserved, charged or received by the Agent, such
Issuing Bank, the Collateral Agent or such Bank, as the case may be, under this
Agreement or any other Credit Document or under any other agreement entered into
in connection with or as security for this Agreement, the Notes or the other
Credit Documents shall under no circumstances exceed the maximum amount allowed
by such applicable law and any excess shall be canceled automatically and, if
theretofore paid, shall at the option of the Agent, such Issuing Bank, the
Collateral Agent or such Bank, as the case may be, be credited by the Agent,
such Issuing Bank, the Collateral Agent or such Bank, as the case may be, on the
principal amount of the obligations owed to the Agent, such Issuing Bank, the
Collateral Agent or such Bank, as the case may be, by the applicable Borrower or
refunded by the Agent, such Issuing Bank, the Collateral Agent or such Bank, as
the case may be, to the applicable Borrower, and (ii) in the event that the
maturity of any obligation payable to the Agent, such Issuing Bank, the
Collateral Agent or such Bank, as the case may be, is accelerated or in the
event of any required or permitted prepayment, then such consideration that
constitutes interest under law applicable to the Agent, such Issuing Bank, the
Collateral Agent or such Bank, as the case may be, may never include more than
the maximum amount allowed by such applicable law and excess interest, if any,
to the Agent, such Issuing Bank, the Collateral Agent or such Bank, as the case
may be, provided for in this Agreement or otherwise shall be canceled
automatically as of the date of such acceleration or prepayment and, if
theretofore paid, shall, at the option of the Agent, such Issuing Bank, the
Collateral Agent or such Bank, as the case may be, be credited by the Agent,
such Issuing Bank, the Collateral Agent or such Bank, as the case may be, on the
principal amount of the obligations owed to the Agent, such Issuing Bank, the
Collateral Agent or such Bank, as the case may be, by the applicable Borrower or
refunded by the Agent, such Issuing Bank, the Collateral Agent or such Bank, as
the case may be, to the applicable Borrower.

      SECTION 8.8. Execution in Counterparts. This Agreement may be executed in
any number of counterparts and by different parties hereto in separate
counterparts, each of which when so executed shall be deemed to be an original
and all of which taken together shall constitute one and the same agreement.
Delivery of a counterpart of a signature page hereof by telecopier shall be as
effective as delivery of an original executed counterpart hereof.



                                      -69-

      SECTION 8.9. Survival of Agreements, Representations and Warranties, Etc.
All warranties, representations and covenants made by any Borrower or any
Authorized Officer of any Borrower herein or in any certificate or other
document delivered in connection with this Agreement shall be considered to have
been relied upon by the Banks and the Issuing Banks and shall survive the
issuance of any Letters of Credit and the issuance and delivery of the Notes (if
any) and the making of Revolving Credit Advances regardless of any
investigation.

      SECTION 8.10. Confidentiality. Each Bank agrees that it will not disclose
without the prior consent of TWC (other than to employees, auditors,
accountants, counsel or other professional advisors of the Collateral Agent, the
Agent, any Issuing Bank or any Bank) any information with respect to the
Borrowers, which is furnished pursuant to this Agreement; provided that any Bank
and any Issuing Bank may disclose any such information (1) as has become
generally available to the public, (2) as may be required or appropriate in any
report, statement or testimony submitted to or required by any regulatory body
having or claiming to have jurisdiction over such Bank or Issuing Bank or
submitted to or required by the Federal Reserve Board or the Federal Deposit
Insurance Corporation or similar organizations (whether in the United States or
elsewhere) or their successors, (3) as may be required or appropriate in
response to any summons or subpoena in connection with any litigation, (4) in
order to comply with any law, order, regulation or ruling applicable to such
Bank or Issuing Bank, (5) to the prospective transferee or grantee in connection
with any contemplated transfer of any of the Commitments, Letter of Credit
Interests or Revolving Credit Advances or any interest therein by such Bank or
Issuing Bank or the grant of an option to an SPC to fund any drawing under a
Letter of Credit or Revolving Credit Advance; provided that such prospective
transferee executes an agreement with or for the benefit of the Borrowers
containing provisions substantially identical to those contained in this Section
8.10; and provided further that if the contemplated transfer is a grant of an
option to fund a drawing under a Letter of Credit or Revolving Credit Advance to
an SPC pursuant to Section 8.5(g), such SPC may disclose, if prior notice of the
delivery thereof is given to the Borrowers, such information as may be required
by law or regulation to be delivered, (6) in connection with the exercise of any
remedy by such Bank or Issuing Bank following an Event of Default, (7) in
connection with any litigation involving such Bank pertaining to this Agreement,
any of the Notes or any of the other Credit Documents or any other document
delivered in connection herewith, (8) to any Bank, any Issuing Bank, the
Collateral Agent or the Agent, (9) to any affiliate of any Bank; provided that
such affiliate has agreed with or for the benefit of the Borrowers to be bound
by provisions substantially identical to those contained in this Section 8.10 or
(10) to any prospective New Letter of Credit Issuing Bank or prospective New
Revolving Bank pursuant to Section 2.19.

      SECTION 8.11. WAIVER OF JURY TRIAL. THE BORROWERS, THE AGENT, THE
COLLATERAL AGENT, THE ISSUING BANKS AND THE BANKS HEREBY IRREVOCABLY WAIVE ANY
AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR
RELATING TO THIS AGREEMENT, ANY OF THE NOTES, ANY LETTER OF CREDIT, ANY OTHER
CREDIT DOCUMENT OR ANY OF THE TRANSACTIONS CONTEMPLATED HEREBY.

      SECTION 8.12. Severability. In the event any one or more of the provisions
contained in this Agreement or in any other Credit Document should be held
invalid, illegal or unenforceable in any respect, the validity, legality and
enforceability of the remaining provisions contained herein and therein shall
not in any way be affected or impaired thereby. The parties shall endeavor in
good-faith negotiations to replace the invalid, illegal or unenforceable
provisions with valid provisions the economic effect of which comes as close as
possible to that of the invalid, illegal or unenforceable provisions.

      SECTION 8.13. FORUM SELECTION AND CONSENT TO JURISDICTION; DAMAGES. ANY
LITIGATION BASED HEREON, OR ARISING OUT OF, UNDER, OR IN CONNECTION



                                      -70-

WITH, ANY CREDIT DOCUMENT, OR ANY COURSE OF CONDUCT, COURSE OF DEALING,
STATEMENTS (WHETHER ORAL OR WRITTEN) OR ACTIONS OF THE AGENT, THE BANKS, ANY
ISSUING BANK, THE COLLATERAL AGENT OR THE BORROWERS IN CONNECTION HEREWITH OR
THEREWITH MAY BE BROUGHT AND MAINTAINED IN THE COURTS OF THE STATE OF NEW YORK
SITTING IN THE COUNTY OF NEW YORK OR IN THE UNITED STATES DISTRICT COURT FOR THE
SOUTHERN DISTRICT OF NEW YORK; PROVIDED, HOWEVER, THAT ANY SUIT SEEKING
ENFORCEMENT AGAINST ANY COLLATERAL OR OTHER SECURITY MAY BE BROUGHT, AT THE
AGENT'S OPTION, IN THE COURTS OF ANY JURISDICTION WHERE SUCH COLLATERAL OR OTHER
SECURITY MAY BE FOUND. THE BORROWERS IRREVOCABLY CONSENT TO THE SERVICE OF
PROCESS BY REGISTERED MAIL, POSTAGE PREPAID, OR BY PERSONAL SERVICE WITHIN OR
WITHOUT THE STATE OF NEW YORK AT THE ADDRESS FOR NOTICES SPECIFIED IN ACCORDANCE
WITH SECTION 8.2. THE BORROWERS HEREBY EXPRESSLY AND IRREVOCABLY WAIVE, TO THE
FULLEST EXTENT PERMITTED BY LAW, ANY OBJECTION WHICH THEY MAY HAVE OR HEREAFTER
MAY HAVE TO THE LAYING OF VENUE OF ANY SUCH LITIGATION BROUGHT IN ANY SUCH COURT
REFERRED TO ABOVE AND ANY CLAIM THAT ANY SUCH LITIGATION HAS BEEN BROUGHT IN AN
INCONVENIENT FORUM. TO THE EXTENT THAT ANY BORROWER HAS OR HEREAFTER MAY ACQUIRE
ANY IMMUNITY FROM JURISDICTION OF ANY COURT OR FROM ANY LEGAL PROCESS (WHETHER
THROUGH SERVICE OR NOTICE, ATTACHMENT PRIOR TO JUDGMENT, ATTACHMENT IN AID OF
EXECUTION OR OTHERWISE) WITH RESPECT TO ITSELF OR ITS PROPERTY, SUCH BORROWER
HEREBY IRREVOCABLY WAIVES TO THE FULLEST EXTENT PERMITTED BY LAW SUCH IMMUNITY
IN RESPECT OF ITS OBLIGATIONS UNDER THE CREDIT DOCUMENTS. EACH OF THE BORROWERS,
THE AGENT, THE COLLATERAL AGENT, THE ISSUING BANKS AND THE BANKS HEREBY
IRREVOCABLY AND UNCONDITIONALLY WAIVES, TO THE FULLEST EXTENT IT MAY EFFECTIVELY
DO SO UNDER APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO CLAIM OR RECOVER IN ANY
ACTION OR PROCEEDING REFERRED TO IN THIS SECTION 8.13 ANY EXEMPLARY, PUNITIVE,
SPECIAL OR CONSEQUENTIAL DAMAGES; PROVIDED THAT NOTHING HEREIN SHALL CONSTITUTE
A WAIVER BY THE AGENT, THE COLLATERAL AGENT, ANY ISSUING BANK OR ANY BANK OF ANY
RIGHT TO RECEIVE FULL PAYMENT OF ALL OBLIGATIONS. TWC HEREBY AGREES TO SERVE AS
AGENT FOR SERVICE OF PROCESS ON BEHALF OF EACH OTHER CREDIT PARTY IN CONNECTION
WITH THE CREDIT DOCUMENTS AND THE OBLIGATIONS.

      SECTION 8.14. Right of Set-off. Upon (i) the occurrence and during the
continuance of any Event of Default and (ii) either (a) the Revolving Credit
Advances owed by any Borrower having become due and payable in accordance with
the terms hereof or (b) the making of the request or the granting of the consent
specified by Section 6.1 to authorize the Agent to declare the Revolving Credit
Advances owed by any Borrower due and payable pursuant to the provisions of
Section 6.1, each Bank and each Issuing Bank is hereby authorized at any time
and from time to time, to the fullest extent permitted by law, to set off and
apply any and all deposits (general or special, time or demand, provisional or
final) at any time held and other indebtedness at any time owing by such Bank or
such Issuing Bank, as the case may be, to or for the credit or the account of
such Borrower against any and all of the obligations of such Borrower now or
hereafter existing under this Agreement and the other Credit Documents,
irrespective of whether or not such Bank or such Issuing Bank, as the case may
be, shall have made any demand under this Agreement or any other Credit Document
and although such obligations may be unmatured. Each Bank or Issuing Bank, as
the case may be, agrees promptly to notify such Borrower after such set-off and
application made by such Bank or such Issuing Bank, as the case may be, provided
that the failure to give such notice shall not affect the validity of such
set-off and application. The rights of each Bank and each



                                      -71-

Issuing Bank under this Section are in addition to other rights and remedies
(including other rights of set-off) which such Bank or such Issuing Bank, as the
case may be, may have.

      SECTION 8.15. Termination of Security Documents and Pipeline Holdco
Guaranty. If (i) the senior unsecured long-term debt of TWC is rated (a) BBB- or
higher by S&P or Baa3 or higher by Moody's, (b) no lower than BB+ by S&P and (c)
no lower than Ba1 by Moody's, (ii) no Default or Event of Default has occurred
and is continuing, and (iii) the Agent has received (1) a notice from Pipeline
Holdco requesting that the Security Documents and the Pipeline Holdco Guaranty
be terminated, (2) a certificate of TWC certifying, as of the date thereof, the
ratings by both S&P and Moody's of such debt and that no Default or Event of
Default has occurred and is continuing, (3) such other documentation confirming
the foregoing that the Agent may reasonably request, then the Security Documents
and the Pipeline Holdco Guaranty shall terminate on the date (the "Collateral
Release Date") that is 5 Business Days following the Agent's receipt of all such
items. With reasonable promptness following such termination, the Collateral
Agent will, at the expense of TWC, execute and deliver (A) to Pipeline Holdco
such documents as Pipeline Holdco may reasonably request to evidence such
termination and will deliver to Pipeline Holdco any Pledged Collateral as may
then be in the Collateral Agent's possession, and Pipeline Holdco will, if
requested by the Collateral Agent, contemporaneously deliver to the Collateral
Agent a written receipt therefor in a reasonable form provided by the Collateral
Agent and (B) to the pledgor of any promissory note delivered to the Collateral
Agent pursuant to Section 5.2(m), such documents as such pledgor may reasonably
request to evidence such termination and any such promissory note as may then be
in the Collateral Agent's possession against the contemporaneous receipt by the
Collateral Agent of a written receipt therefor in a reasonable form provided by
the Collateral Agent.

      SECTION 8.16. Change of Certain Parties. Effective as of the date hereof,
(i) MLP is hereby added to this Agreement as a Borrower and (ii) each Bank (as
defined in the 2004 Credit Agreement) that is not a party to this Agreement is
deleted as a party to each Credit Document.

      SECTION 8.17. Releases. Upon delivery of the Pledge and the creation of
security interest created thereby, the Western Midstream Guaranty (as defined in
the 2004 Credit Agreement) and the Existing Security Documentation is hereby
terminated (except those provisions thereof that survive in accordance with the
express terms thereof) including release of all Liens thereunder. TWC hereby
requests, on behalf of the Borrowers, Pipeline Holdco and the Western Midstream
Subsidiaries (as defined in the 2004 Credit Agreement), that the Collateral
Agent execute and deliver to TWC or one or more of its Subsidiaries the
terminations and releases referred to on Schedule V, substantially
simultaneously with the delivery to the Collateral Agent of the Pledge and the
stock of TGPL covered thereby on the date hereof, and the Collateral Agent
agrees to do so. Additionally, the Collateral Agent agrees to execute and
deliver to TWC or one or more of its Subsidiaries, at TWC's expense, such
additional terminations and releases as TWC may reasonably request after the
date hereof to fully effectuate the terminations and release contained in the
first sentence of this Section 8.17. Each Bank and each Issuing Bank hereby
consent to such terminations and release and authorize the Collateral Agent to
execute all terminations, releases and other documents in connection therewith.
