         October 16 through October 20 was Rating Category Five and thereafter
         was Rating Category Four, the Applicable Margin for such Advance would

         Borrower more than six A Borrowings comprised of Eurodollar Rate
         Advances;

                 (ii)     no Borrower may select Eurodollar Rate Advances for
         any Borrowing if the aggregate amount of such Borrowing is less than
         (x) if such Borrowing is made by WPL, $5,000,000, and (y) if such
         Borrowing is made by any other Borrower, $20,000,000;

                 (iii)    if the Majority Banks shall notify the Agent that
         either (A) the Eurodollar Rate for any Interest Period for any
         Eurodollar Rate Advances will not adequately reflect the cost to such
         Banks of making or funding their respective Eurodollar Rate Advances
         for such Interest Period, or (B) that U.S. dollar deposits for the
         relevant amounts and Interest Period for their respective Advances are
         not available to them in the London interbank market, or it is
         otherwise impossible to have Eurodollar Rate Advances, the Agent shall
         forthwith so notify the Borrowers and the Banks, whereupon (1) 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 obligations of the Banks to make, or to Convert
         Advances into, Eurodollar Rate Advances shall be suspended until the
         Agent, at the request of the Majority Banks, shall notify the
         Borrowers and the Banks that the circumstances causing such suspension
         no longer exist, and, except as provided in Section 2.02(b)(v), each
         Advance comprising any requested A Borrowing shall be a Base Rate
         Advance;

                 (iv)     if the Agent is unable to determine the Eurodollar
         Rate for Eurodollar Rate Advances, the obligation of the Banks to
         make, or to Convert 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 2.02(b)(v), each Advance comprising any
         requested A Borrowing shall be a Base Rate Advance; and

                 (v)      if a Borrower has requested a proposed A Borrowing
         consisting of Eurodollar Rate Advances and as a result of
         circumstances referred to in Section 2.02(b)(iii) or (iv) such A
         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 A Borrowing
         would otherwise be made, cancel such A Borrowing, in which case such A
         Borrowing shall be cancelled and no Advances shall be made as a


                                      -17-
   22
         result of such requested A Borrowing, but such Borrower shall
         indemnify the Banks in connection with such cancellation as
         contemplated by Section 2.02(c).

                 (c)      Each Notice of A Borrowing shall be irrevocable and
binding on the Borrowers, except as set forth in Section 2.02(b)(v).  In the
case of any A Borrowing requested by a Borrower which the related Notice of A
Borrowing specifies is to be comprised of Eurodollar Rate Advances, such
Borrower shall indemnify each Bank against any loss, cost or expense incurred
by such Bank as a result of any failure to fulfill on or before the date
specified in such Notice of A Borrowing for such A Borrowing the applicable
conditions set forth in Article III, including, without limitation, any loss
(including loss of reasonably anticipated profits), cost or expense incurred by
reason of the liquidation or reemployment of deposits or other funds acquired
by such Bank to fund the A Advance to be made by such Bank as part of such A
Borrowing when such A Advance, as a result of such failure, is not made on such
date. A certificate in reasonable detail as to the basis for and the amount of
such loss, cost or expense submitted to such Borrower and the Agent by such
Bank shall be prima facie evidence of the amount of such loss, cost or expense.
If an A Borrowing requested by a Borrower which the related Notice of A
Borrowing specifies is to be comprised of Eurodollar Rate Advances is not made
as an A Borrowing comprised of Eurodollar Rate Advances as a result of Section
2.02(b), such Borrower shall indemnify each Bank against any loss (excluding
loss of profits), cost or expense incurred by such Bank by reason of the
liquidation or reemployment of deposits or other funds acquired by such Bank
prior to the time such Bank is actually aware that such A Borrowing will not be
so made to fund the A Advance to be made by such Bank as part of such A
Borrowing. A certificate in reasonable detail as to the basis for and the
amount of such loss, cost or expense submitted to such Borrower and the Agent
by such Bank shall be prima facie evidence of the amount of such loss, cost or
expense.

                 (d)      Unless the Agent shall have received notice from a
Bank prior to the date of any A Borrowing to a Borrower that such Bank will not
make available to the Agent such Bank's ratable portion of such A Borrowing,
the Agent may assume that such Bank has made such portion available to the
Agent on the date of such A Borrowing in accordance with subsection (a) of this
Section 2.02 and the Agent may, in reliance upon such assumption, make
available to such Borrower requesting such A Borrowing 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 such 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 A Advances comprising such A 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 A
Advance as part of such A Borrowing for purposes of this Agreement.

   23
                 (e)      The failure of any Bank to make the A Advance to be
made by it as part of any A Borrowing shall not relieve any other Bank of its
obligation, if any, hereunder to make its A Advance on the date of such A
Borrowing, but no Bank shall be responsible for the failure of any other Bank
to make the A Advance to be made by such other Bank on the date of any A
Borrowing.

                 Section 2.03.  Fees.

                 (a)      Commitment Fee. TWC agrees to pay to the Agent for
the account of each Bank a commitment fee on the average daily unused (for the
purposes of this Section 2.03(a) A Advances made to any Borrower shall be
considered to have been made to TWC, but B Advances to any Borrower shall not,
for purposes of this Section 2.03(a), be considered to be usage of any
Commitment) portion of such Bank's Commitment to TWC from the date hereof until
the Termination Date at a rate per annum from time to time equal to (i) at such
times as Rating Category One is applicable to TWC, .10%, (ii) at such times as

Category Three is applicable to TWC, .15%, (iv) at such times as Rating
Category Four is applicable to TWC, .20%, (v) at such times as Rating Category
Five is applicable to TWC, .30%, (vi) at such times as Rating Category Six is
applicable to TWC, .375% and (vii) at such times as Rating Category Seven is
applicable to TWC, .50%, payable in arrears on the last day of each March,
June, September and December during the term such Bank has any Commitment to
any Borrower and on the Termination Date.

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

                 Section 2.04.  Reduction of the Commitments.  (a) Optional.
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 the unused portions
of the respective Commitments of the Banks to such Borrower, provided that each
partial reduction shall be in the aggregate amount of at least $20,000,000, and
provided further, that the aggregate amount of the Commitments of the Banks to
any Borrower shall not be reduced to an amount which is less than the aggregate
principal amount of the Advances then outstanding to such Borrower, and
provided further, that the aggregate amount of the Commitments of the Banks to
TWC shall not be reduced to an amount which is less than the aggregate
principal amount of the Advances then outstanding to the Borrower as to which
the aggregate outstanding principal amount of Advances is then the largest.

                 (b)      Termination.  If all of the Commitments of the Banks
to a Borrower (other than TWC) are terminated pursuant to Section 2.04(a) and
such Borrower has paid all principal, interest, fees, costs and other amounts
owed by it hereunder and under the Notes executed by it, such Borrower shall
have the right, upon


                                      -19-
   24
at least three Business Days notice to the Agent, to elect to cease to be a
Borrower hereunder, except for purposes of the definition herein of Majority
Banks and for purposes of Sections 2.11, 2.14 and 8.04.

                 Section 2.05.  Repayment of A Advances.  Each Borrower shall
repay, on the Stated Termination Date or such earlier date as the Notes may be
declared due pursuant to Article VI, the unpaid principal amount of each A
Advance made by each Bank to such Borrower.

                 Section 2.06.  Interest on A Advances. Each Borrower shall pay
interest on the unpaid principal amount of each A Advance made by each Bank to
such Borrower from the date of such A Advance until such principal amount shall
be paid in full, at the following rates per annum:

                 (a)      Base Rate Advances. At such times as such A Advance
         is a Base Rate Advance, a rate per annum equal at all times to the
         Base Rate in effect from time to time plus the Applicable Margin in
         effect from time to time for such A Advance, payable quarterly in
         arrears on the last day of each March, June, September and December
         and on the date such Advance shall be Converted or paid in full;
         provided that any amount of principal of any Base Rate Advance,
         interest, fees and other amounts payable hereunder (other than
         principal of any Eurodollar Rate Advance) which is not paid when due
         (whether at stated maturity, by acceleration or otherwise) shall bear
         interest, from the date on which such amount is due until such amount
         is paid in full, payable on demand, at a rate per annum equal at all
         times to the sum of the Base Rate in effect from time to time plus the
         Applicable Margin for Base Rate Advances to such Borrower in effect
         from time to time plus 2% per annum.

                 (b)      Eurodollar Rate Advances. At such times as such A
         Advance is a Eurodollar Rate Advance, a rate per annum equal at all
         times during each Interest Period for such A Advance to the sum of the
         Eurodollar Rate for such Interest Period plus the Applicable Margin in
         effect from time to time for such A Advance, payable on the last day
         of such Interest Period and, if such Interest Period has a duration of
         more than three months, on each day which occurs during such Interest
         Period every three months from the first day of such Interest Period;
         provided that any amount of principal of any Eurodollar Rate Advance
         which is not paid when due (whether at stated maturity, by
         acceleration or otherwise) shall bear interest, from the date on which
         such amount is due until such amount is paid in full, payable on
         demand, at a rate per annum equal at all times to the greater of (x)
         the sum of the Base Rate in effect from time to time plus the
         Applicable Margin for Base Rate Advances to such Borrower in effect
         from time to time plus 2% per annum and (y) the sum of the rate per
         annum required to be paid on such A Advance immediately prior to the
         date on which such amount became due plus 2% per annum.

   25
                 Section 2.07.  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 Board of Governors of the Federal Reserve
System 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 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 (i) the Eurodollar Rate for the Interest Period for such Advance
from (ii) 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
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 2.07 for any period more than 90 days prior to the date such Bank
notifies the Borrowers that additional interest may be charged pursuant to this
Section 2.07.

                 Section 2.08.  Interest Rate Determination. The Agent shall
give prompt notice to the Borrower to which an A Advance is made and the Banks
of the applicable interest rate for each Eurodollar Rate Advance determined by
the Agent for purposes of Section 2.06(b).

                 Section 2.09.  Evidence of Debt. The indebtedness of each
Borrower resulting from the A Advances owed to each Bank by such Borrower shall
be evidenced by an A Note of such Borrower payable to the order of such Bank.

                 Section 2.10.  Prepayments.

                 (a)      No Borrower shall have any right to prepay any
principal amount of any A Advance except as provided in this Section 2.10.

                 (b)      Any Borrower may, in respect of Base Rate Advances
upon notice to the Agent before 10:00 A.M.  (New York City time) on the date of
prepayment, and in respect of Eurodollar Rate Advances upon at least three
Business Days' notice to the Agent, in each case stating the proposed date
(which shall be a Business Day) and aggregate principal amount of the
prepayment, and if such notice is given such Borrower shall, prepay the
outstanding principal amounts of the A Advances comprising part of the same A
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 to Section 8.04(b) as a result of such prepayment;
provided, however, that each partial prepayment pursuant to this Section
2.10(b) shall be in an aggregate principal amount not less than $5,000,000 and
in an aggregate


                                      -21-
   26
principal amount such that after giving effect thereto no A Borrowing comprised
of Base Rate Advances shall have a principal amount outstanding of less than
$5,000,000 and no A Borrowing comprised of Eurodollar Rate Advances shall have
a principal amount outstanding of less than (i) if such A Borrowing was made by
WPL, $5,000,000, and (ii) if such A Borrowing was made by any other Borrower,
$20,000,000.

                 (c)      Each Borrower will give notice to the Agent at or
before the time of each prepayment by such Borrower of Advances pursuant to
this Section 2.10 specifying the Advances which are to be prepaid and the
amount of such prepayment to be applied to such Advances, and each payment of
any Advance pursuant to this Section 2.10 or any other provision of this
Agreement shall be made in a manner such that all Advances comprising part of
the same Borrowing are paid in whole or ratably in part.

                 Section 2.11.  Increased Costs. (a) 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 or request from any
central bank or other governmental authority (whether or not having the force
of law), 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, 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. 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 the Borrowers of any such introduction, change,
compliance or proposed compliance.

                 (b)      If any Bank determines that compliance with any law
or regulation or any guideline or request from any central bank or other
governmental authority (whether or not having the force of law) affects or
would affect the amount of capital required or expected to be maintained by
such Bank or any corporation controlling such Bank and that the amount of such
capital is increased by or based upon the existence of such Bank's commitment
to lend to any Borrower hereunder and other commitments of this type, then,
upon demand by such Bank (with a copy of such demand to the Agent), such
Borrower shall immediately pay to the Agent for the account of such Bank, from
time to time as specified by such Bank, additional amounts sufficient to
compensate such Bank or such corporation in the light of such circumstances, to
the extent that such Bank reasonably determines such increase in capital to be
allocable to the existence of such Bank's commitment to lend hereunder.  A
certificate as to the amount of such additional amounts, submitted to such
Borrower and the Agent by such



                                      -22-
   27
Bank, shall be prima facie evidence of the amount of such additional amounts.
No Bank shall have any right to recover any additional amounts under this
Section 2.11(b) for any period more than 90 days prior to the date such Bank
notifies the Borrower of any such compliance.

                 (c)      In the event that any Bank makes a demand for payment
under Section 2.07 or this Section 2.11, TWC may within ninety days of such
demand, if no Event of Default or event which, with the giving of notice or
lapse of time or both, would constitute an Event of Default then exists,
replace such Bank with another commercial bank in accordance with all of the
provisions of the last sentence of Section 8.06(a) (including execution of an
appropriate Transfer Agreement) provided that (i) all obligations of such Bank
to lend hereunder shall be terminated and the 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 at or prior to such replacement,
(ii) such replacement bank shall be reasonably satisfactory to the Agent and
the Majority Banks, (iii) such replacement bank shall, from and after such
replacement, be deemed for all purposes to be a "Bank" hereunder with a
Commitment to each Borrower in the amount of the respective Commitment of such
Bank to such Borrower immediately prior to such replacement (plus, if such
replacement bank is already a Bank prior to such replacement the respective
Commitment of such Bank to such Borrower 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, and
(iv) 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, without
limitation, execution and delivery of new Notes of each Borrower to such
replacement bank, redelivery to each Borrower in due course of the Notes of
such Borrower payable to such Bank and specification of the information
contemplated by Schedule I as to such replacement bank).

                 Section 2.12.  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 shall make it unlawful, or that any central bank or other
governmental authority shall assert that it is unlawful, for any Bank or its
Eurodollar Lending Office to perform its obligations hereunder to make, or
Convert a Base Rate Advance into, a Eurodollar Rate Advance or to continue to
fund or maintain any Eurodollar Rate Advance, then, on notice thereof to the
Borrowers by the Agent, (i) the obligation of each of the Banks to make, or to
Convert Advances into, Eurodollar Rate Advances shall be suspended until the
Agent, at the request of the Majority Banks, shall notify the Borrowers and the
Banks that the circumstances causing such suspension no longer exist, and (ii)
the Borrowers shall forthwith prepay in full all Eurodollar Rate Advances of
all Banks then outstanding together with all accrued interest thereon and all
amounts payable pursuant to Section 8.04(b), unless


                                      -23-
   28
each Bank shall determine in good faith in its sole opinion that it is lawful
to maintain the Eurodollar Rate Advances made by such Bank to the end of the
respective Interest Periods then applicable thereto or unless the Borrower,
within five Business Days of notice from the Agent, Converts all Eurodollar
Rate Advances of all Banks then outstanding into Base Rate Advances in
accordance with Section 2.19.

                 Section 2.13.  Payments and Computations.  (a) Each Borrower
shall make each payment hereunder and under the Notes to be made by it not
later than 11:00 A.M. (New York City time) on the day when due in U.S. dollars
to the Agent at its New York address referred to in Section 8.02 in same day
funds. The Agent will promptly thereafter cause to be distributed like funds
relating to the payment of principal, interest or commitment fees ratably
(other than amounts payable pursuant to Section 2.07, 2.11, 2.14, 2.16 or
8.04(b)) 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 to such Bank for the account of its Applicable Lending Office, in each
case to be applied in accordance with the terms of this Agreement. In no event
shall any Bank be entitled to share any fee paid to the Agent pursuant to
Section 2.03(b), any auction fee paid to the Agent pursuant to Section
2.16(a)(i) or any other fee paid to the Agent, as such.

                 (b)      Each Borrower hereby authorizes each Bank, if and to
the extent payment owed to such Bank by such Borrower is not made when due
hereunder or under any Note of such Borrower held by such Bank, to charge from
time to time against any or all of such Borrower's accounts with such Bank any
amount so due.

                 (c)      All computations of interest based on clause (a) or
clause (b) of the definition herein of Base Rate and of commitment fees shall
be made by the Agent on the basis of a year of 365 or 366 days, as the case may
be, and all computations of interest based on the Eurodollar Rate, the Federal
Funds Rate  or clause (c) of the definition herein of Base Rate shall be made
by the Agent, and all computations of interest pursuant to Section 2.07
shall be made by a Bank, 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 or commitment fees are payable.
Each determination by the Agent (or, in the case of Section 2.07, by a Bank) of
an interest rate hereunder shall be conclusive and binding for all purposes,
absent manifest error.

                 (d)      Whenever any payment hereunder or under the Notes
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 or
commitment fee, as the case may be; provided, however, 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.




                                      -24-
   29
                 (e)      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.  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 2.14.  Taxes.  (a) Any and all payments by any
Borrower hereunder or under the Notes shall be made, in accordance with Section
2.13, 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 and the Agent, taxes imposed on its income, and franchise taxes
imposed on it, by the jurisdiction under the laws of which such Bank or the
Agent (as the case may be) is organized or any political subdivision thereof
and, in the case of each Bank, taxes imposed on its income, 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 or the Agent, (i) the sum payable shall be increased as may be
necessary so that after making all required deductions (including deductions
applicable to additional sums payable under this Section 2.14) such Bank or the
Agent (as the case may be) receives an amount equal to the sum it would have
received had no such deductions 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.

                 (b)      In addition, each Borrower agrees to pay any present
or future stamp or documentary taxes or any other excise or property taxes,
charges or similar levies which arise from any payment made by such Borrower
hereunder or under the Notes executed by it or from the execution, delivery or
registration of, or otherwise with respect to, this Agreement or such Notes
(hereinafter referred to as "Other Taxes").

                 (c)      Each Borrower will indemnify each Bank and the Agent
for the full amount of Taxes or Other Taxes (including, without limitation, any
Taxes or Other Taxes imposed by any jurisdiction on amounts payable under this
Section 2.14) owed and paid by such 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 or the Agent  (as the case may be) makes written demand
therefor.





                                      -25-
   30
                 (d)      Within 30 days after the date of the 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 8.02, the original or a certified
copy of a receipt evidencing payment thereof.  Should any Bank or the Agent
ever receive any refund, credit or deduction from any taxing authority to which
such Bank or the Agent would not be entitled but for the payment by a Borrower
of Taxes as required by this Section 2.14 (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 or the Agent, as
the case may be, in its sole discretion), such 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 or the Agent, as the case may be, and determined by such
Bank or the Agent, as the case may be, to be attributable to such refund,
credit or deduction.

                 (e)      Without prejudice to the survival of any other
agreement of the Borrowers hereunder, the agreements and obligations of the
Borrowers contained in this Section 2.14 shall survive the payment in full of
principal and interest hereunder and under the Notes.

                 Section 2.15. 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 A Advances made by it
(other than pursuant to Section 2.07, 2.11, 2.14 or 8.04(b)) in excess of its
ratable share of payments on account of the A Advances obtained by all the
Banks, such Bank shall forthwith purchase from the other Banks such
participations in the A Advances owed to them as shall be necessary to cause
such purchasing Bank to share the excess payment ratably with each of them,
provided, however, 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 2.15 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.

                 Section 2.16. The B Advances. (a) Each Bank severally agrees
that each Borrower may make B Borrowings under this Section 2.16 from time to
time on any Business Day during the period from the date hereof until the
earlier of (I) the





                                      -26-
   31
Termination Date or (II) the date occurring 30 days prior to the Stated
Termination Date in the manner set forth below; provided that, following the
making of each B Borrowing, the aggregate amount of the Advances then
outstanding to such Borrower shall not exceed the aggregate amount of the
Commitments of the Banks to such Borrower (computed without regard to any B
Reduction) and the aggregate amount of all Advances then outstanding shall not
exceed the aggregate amount of the Commitments of the Banks to TWC (computed
without regard to any B Reduction).

                 (i)      A Borrower may request a B Borrowing under this
         Section 2.16 by delivering to the Agent, by telecopier, telex or
         cable, confirmed immediately in writing, a notice of a B Borrowing (a
         "Notice of B Borrowing"), in substantially the form of Exhibit B-2
         hereto, specifying the date and aggregate amount of the proposed B
         Borrowing, the maturity date for repayment of each B Advance to be
         made as part of such B Borrowing (which maturity date may not be
         earlier than the date occurring 14 days after the date of such B
         Borrowing or later than the earlier of (x) 6 months after the date of
         such B Borrowing or (y)  the Stated Termination Date), the interest
         payment date or dates relating thereto, and any other terms to be
         applicable to such B Borrowing (including, without limitation, the
         basis to be used by the Banks in determining the rate or rates of
         interest to be offered by them as provided in paragraph (ii) below and
         prepayment terms, if any, but excluding any waiver or other
         modification to any of the conditions set forth in Article III), not
         later than 10:00 A.M. (New York City time) (A) at least one Business
         Day prior to the date of the proposed B Borrowing, if such Borrower
         shall specify in the Notice of B Borrowing that the rates of interest
         to be offered by the Banks shall be fixed rates per annum and (B) at
         least five Business Days prior to the date of the proposed B
         Borrowing, if the Borrower shall instead specify in the Notice of B
         Borrowing the basis to be used by the Banks in determining the rates
         of interest to be offered by them.  The Agent shall in turn promptly
         notify each Bank of each request for a B Borrowing received by it from
         a Borrower by sending such Bank a copy of the related Notice of B
         Borrowing.  Each time that a Borrower gives a Notice of B Borrowing,
         such Borrower shall pay to the Agent an auction fee equal to $250
         times the number of Banks at such time.

                 (ii)     Each Bank may, if in its sole discretion it elects to
         do so, irrevocably offer to make one or more B Advances to a Borrower
         as part of such proposed B Borrowing at a rate or rates of interest
         specified by such Bank in its sole discretion, by notifying the Agent
         (which shall give prompt notice thereof to such Borrower), before
         10:00 A.M. (New York City time) (x) on the date of such proposed B
         Borrowing, in the case of a Notice of B Borrowing delivered pursuant
         to clause (A) of paragraph (i) above, and (y) three Business Days
         before the date of such proposed B Borrowing in the case of a Notice
         of B Borrowing delivered pursuant to clause (B) of paragraph (i)
         above, of the minimum amount and maximum amount of each B Advance
         which such Bank





                                      -27-
   32
         would be willing to make as part of such proposed B Borrowing (which
         amounts may, subject to the proviso to the first sentence of this
         Section 2.16(a), exceed such Bank's Commitment to such Borrower), the
         rate or rates of interest therefor and such Bank's Applicable Lending
         Office with respect to such B Advance; provided that if the Agent in
         its capacity as a Bank shall, in its sole discretion, elect to make
         any such offer, it shall notify such Borrower of such offer before
         9:45 A.M. (New York City time) on the date on which notice of such
         election is to be given to the Agent by the other Banks.  If any Bank
         shall elect not to make such an offer, such Bank shall so notify the
         Agent, before 10:00 A.M. (New York City time) on the date on which
         notice of such election is to be given to the Agent by the other
         Banks, and such Bank shall not be obligated to, and shall not, make
         any B Advance as part of such B Borrowing; provided that the failure
         by any Bank to give such notice shall not cause such Bank to be
         obligated to make any B Advance as part of such proposed B Borrowing.

                 (iii)    The Borrower requesting such proposed B Borrowing
         shall, in turn, before 11:00 A.M. (New York City time) (x) on the
         date of such proposed B Borrowing in the case of a Notice of B
         Borrowing delivered pursuant to clause (A) of paragraph (i) above and
         (y) three Business Days before the date of such proposed B Borrowing
         in the case of a Notice of B Borrowing delivered pursuant to clause
         (B) of paragraph (i) above, either

                          (A)     cancel such B Borrowing by giving the
                 Agent notice to that effect, or

                          (B)     accept one or  more  of  the  offers  made
                 by any Bank or Banks pursuant to paragraph (ii) above, in
                 order of the  lowest  to  highest rates of interest or margins
                 (or, if two or more Banks bid at the same rates of interest,
                 and the amount of accepted offers is less than the aggregate
                 amount of such offers, the amount to be borrowed from such
                 Banks as part of such B Borrowing shall be allocated among
                 such Banks pro rata on the basis of the maximum amount offered
                 by such Banks at such rates or margin in connection with such
                 B Borrowing), in any aggregate amount up to the aggregate
                 amount initially requested by the Borrower in the relevant
                 Notice of B Borrowing, by giving notice to the Agent of the
                 amount of each B Advance (which amount shall be equal to or
                 greater than the minimum amount, and equal to or less than the
                 maximum amount, notified to such Borrower by the Agent on
                 behalf of such Bank for such B Advance pursuant to paragraph
                 (ii) above) to be made by each Bank as part of such B
                 Borrowing, and reject any remaining offers made by Banks
                 pursuant to paragraph (ii) above by giving the Agent notice to
                 that effect.

   33
                 (iv)     If the Borrower requesting such B Borrowing notifies
         the Agent that such B Borrowing is cancelled pursuant to paragraph
         (iii)(A) above, the Agent shall give prompt notice thereof to the
         Banks and such B Borrowing shall not be made.

                 (v)      If the Borrower requesting such B Borrowing accepts
         one or more of the offers made by any Bank or Banks pursuant to
         paragraph (iii)(B) above, the Agent shall in turn promptly notify (A)
         each Bank that has made an offer as described in paragraph (ii) above,
         of the date and aggregate amount of such B Borrowing and whether or
         not any offer or offers made by such Bank pursuant to paragraph (ii)
         above have been accepted by such Borrower, (B) each Bank that is to
         make a B Advance as part of such B Borrowing, of the amount of each B
         Advance to be made by such Bank as part of such B Borrowing, and (C)
         each Bank that is to make a B Advance as part of such B Borrowing,
         upon receipt, that the Agent has received forms of documents appearing
         to fulfill the applicable conditions set forth in Article III.  Each
         Bank that is to make a B Advance as part of such B Borrowing shall,
         before 12:00 noon (New York City time) on the date of such B Borrowing
         specified in the notice received from the Agent pursuant to clause (A)
         of the preceding sentence or any later time when such Bank shall have
         received notice from the Agent pursuant to clause (C) of the preceding
         sentence, make available for the account of its Applicable Lending
         Office to the Agent at its New York address referred to in Section
         8.02 such Bank's portion of such B Borrowing, in same day funds.  Upon
         fulfillment of the applicable conditions set forth in Article III and
         after receipt by the Agent of such funds, the Agent will make such
         funds available to such Borrower at the Agent's aforesaid address.
         Promptly after each B Borrowing the Agent will notify each Bank of the
         amount of the B Borrowing, the Borrower to which such B Borrowing was
         made, the consequent B Reduction and the dates upon which such B
         Reduction commenced and will terminate.

                 (b)      Each B Borrowing shall be in an aggregate amount of
         not less than $5,000,000 or an integral multiple of $1,000,000 in
         excess thereof.  Each Borrower agrees that it will not request a B
         Borrowing unless, upon the making of such B Borrowing, the limitations
         set forth in the proviso to the first sentence of Section 2.16(a) are
         complied with.

                 (c)      Within the limits and on the conditions set forth in
         this Section 2.16,  each Borrower may from time to time borrow under
         this Section 2.16, repay or prepay pursuant to subsection (d) below,
         and reborrow under this Section 2.16, provided that a B Borrowing
         shall not be made by any Borrower within three Business Days of the
         date of another B Borrowing to such Borrower.

                 (d)      Each Borrower shall repay to the Agent for the
         account of each Bank which has made a B Advance to such Borrower, or
         each other holder of a B Note of such Borrower, on the maturity date
         of each B Advance made to such Borrower (such maturity date being that
         specified by such Borrower for repayment of such B Advance in the
         related Notice of B Borrowing delivered pursuant to subsection (a)(i)
         above and provided in the B Note evidencing such B Advance) the then
         unpaid principal amount of such B Advance.  No Borrower shall have any
         right to prepay any principal amount of any B Advance unless, and then
         only on the terms, specified by such Borrower for such B Advance in
         the related Notice of B Borrowing delivered pursuant to subsection
         (a)(i) above and set forth in the B Note evidencing such B Advance.

                 (e)      Each Borrower shall pay interest on the unpaid
         principal amount of each B Advance made to such Borrower from the date
         of such B Advance to the date the principal amount of such B Advance
         is repaid in full, at the rate of interest for such B Advance
         specified by the Bank making such B Advance in its notice with respect
         thereto delivered pursuant to subsection (a)(ii) above, payable on the
         interest payment date or dates specified by such Borrower for such B
         Advance in the related Notice of B Borrowing delivered pursuant to
         subsection (a)(i) above, as provided in the B Note evidencing such B
         Advance.

                 (f)      The indebtedness of each Borrower resulting from each
         B Advance made to such Borrower as part of a B Borrowing shall be
         evidenced by a separate B Note of such Borrower payable to the order
         of the Bank making such B Advance.

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

                 Section 2.17. Optional Termination.  Notwithstanding anything
to the contrary in this Agreement, if (i) any Person (other than a trustee or
other fiduciary holding securities under an employee benefit plan of TWC or of
any Subsidiary of TWC) or two or more Persons acting in concert (other than any
group of employees of TWC or of any of its Subsidiaries) shall have acquired
beneficial ownership (within the meaning of Rule 13d-3 of the Securities and
Exchange Commission under the Securities Exchange Act of 1934), directly or
indirectly, of securities of TWC (or other securities convertible into such
securities) representing 20% or more of the combined voting power of all
securities of TWC entitled to vote in the election of directors, other than
securities having such power only by reason of the happening of a contingency,
or (ii) during any period of up to 24 consecutive months, commencing before or
after the date of this Agreement, individuals who at the beginning of such
24-month period were





                                      -30-
   35
directors of TWC or who were elected by individuals who at the beginning of
such period were such directors or by individuals elected in accordance with
this clause (ii) shall cease for any reason to constitute a majority of the
board of directors of TWC, or (iii) any Person (other than TWC or a
Wholly-Owned Subsidiary of TWC) or two or more Persons acting in concert shall
have acquired by contract or otherwise, or shall have entered into a contract
or arrangement which upon consummation will result in its or their acquisition
of, the power to exercise, directly or indirectly, a controlling influence over
the management or policies of any Borrower; then the Agent shall at the
request, or may with the consent, of the holders of at least 66-2/3% in
principal amount of the A Notes then outstanding or, if no A Notes are then
outstanding, Banks having at least 66-2/3% of the Commitments, by notice to the
Borrowers, declare all of the Commitments and the obligation of each Bank to
make Advances to be terminated, whereupon all of the Commitments and each such
obligation shall forthwith terminate, and no Borrower shall have any further
right to borrow hereunder.

         Section 2.18. Extension of Termination Date.  By notice given to the
Agent and the Banks, at least thirty days but not more than forty-five days
before February 1 of any year after 1998, the Borrowers may request the Banks
to extend the Stated Termination Date for an additional year to a date which is
an anniversary date of the Stated Termination Date.  Within thirty days after
receipt of such request, each Bank that agrees, in its sole and absolute
discretion, to so extend the Stated Termination Date shall notify the Borrowers
and the Agent that it so agrees, and if all Banks so agree the Stated
Termination Date shall be so extended.

         Section 2.19. Voluntary Conversion of Advances.  Any Borrower may on
any Business Day, if no Event of Default then exists as to such Borrower, upon
notice (which shall be irrevocable) given to the Agent not later than 11:00
A.M.  (x) in the case of a proposed Conversion into Eurodollar Rate Advances,
on the third Business Day prior to the date of the proposed conversion, and (y)
in the case of a proposed Conversion into Base Rate Advances, on the date of
the proposed Conversion, and subject to the provisions of Sections 2.02 and
2.12, Convert all Advances of one Type comprising the same A Borrowing into
Advances of the other Type; provided that (i) no Conversion of any Eurodollar
Rate Advances shall occur on a day other than the last day of an Interest
Period for such Eurodollar Rate Advances, except as contemplated by Section
2.12, and (ii) Advances may not be Converted into Eurodollar Rate Advances if
the aggregate unpaid principal amount of the Advances is less than $20,000,000.
Each such notice of a Conversion shall, within the restrictions specified
above, specify (i) the date of such Conversion, (ii) the A Advances to be
Converted, and (iii) if such Conversion is into Eurodollar Rate Advances, the
duration of the Interest Period for each such Advance.

         Section 2.20. Automatic Provisions. (a) If any Borrower shall fail to
select the duration of any Interest Period for Eurodollar Rate Advances in
accordance with the provisions contained in the definition of "Interest Period"
in Section 1.01, the





                                      -31-
   36
Agent will forthwith so notify such Borrower and the Lenders, and such Advances
will automatically, on the last day of the then existing Interest Period
therefor, Convert into Base Rate Advances.

                 (b)      On the date on which the aggregate unpaid principal
         amount of the Eurodollar Rate Advances of any Borrower shall be
         reduced to less than $20,000,000, all of such Eurodollar Rate Advances
         shall automatically Convert into Base Rate Advances.

         Section 8.10 thereof) and that all principal, interest and other
         amounts owed thereunder have been paid in full.  Each Bank hereby

Borrowing.  The obligation of each Bank to make an A Advance to a Borrower on
the occasion of any A Borrowing (including the initial A Borrowing) shall be

such Borrower that on the date of such A Borrowing such statements are true):

                 (i)      The representations and warranties contained in

         proceeds therefrom, as though made on and as of such date,

                 (ii)     No event has occurred and is continuing, or would
         result from such A Borrowing or from the application of the proceeds

         Borrowings which have been requested on or prior to such date but
         which have not been made prior to such date, the aggregate principal

                 (1)      The representations and warranties contained in
         Section 4.01 pertaining to such Borrower and its Subsidiaries are
         correct on and as of the date of such B Borrowing, before and after

                 Section 4.01. Representations and Warranties of the Borrowers.
Each Borrower represents and warrants as to itself and its Subsidiaries as

                 (a)      Each Borrower is a corporation duly organized,
         validly existing and in good standing under the laws of the State of
         Delaware and has all corporate powers and all governmental licenses,
         authorizations, certificates, consents and approvals required to carry
         on its business as now conducted in all material respects, except for

         material adverse effect on the business, assets, condition or
         operation of such Borrower and its Subsidiaries taken as a whole.
         Each Subsidiary of each Borrower is a corporation duly organized,
         validly existing and in good standing under the laws of its
         jurisdiction of incorporation, except where the failure to be so
         organized, existing and in good standing could not reasonably be
         expected to have a material adverse effect on the business, assets,
         condition or operations of such Borrower and its Subsidiaries taken as
         a whole.  Each Subsidiary of a Borrower has all corporate powers and
         all governmental licenses, authorizations, certificates, consents and

         Subsidiaries taken as a whole.

                 (b)      The execution, delivery and performance by each
         Borrower of this Agreement and  the Notes and the consummation of the
         transactions contemplated by this Agreement are within such Borrower's

         action, do not contravene (i) such Borrower's charter or by-laws or
         (ii) law or any contractual restriction binding on or affecting such
         Borrower and will not result in or require the creation or imposition
         of any Lien prohibited by this Agreement.  At the time of each
         borrowing of any Advance by a Borrower, such borrowing and the use of
         the proceeds of such Advance will be within such Borrower's corporate
         powers, will have been duly authorized by all necessary corporate
         action, will not contravene (i) such Borrower's charter or by-laws or

         contractual restriction binding on or affecting such Borrower and will
         not result in or require the creation or imposition of any Lien
         prohibited by this Agreement.

                 (c)      No authorization or approval or other action by, and
         no notice to or filing with, any governmental authority or regulatory
         body is required for the due execution, delivery and performance by
         any Borrower of this Agreement or the Notes or the consummation of the
         transactions contemplated by this Agreement. At the time of each
         borrowing of any Advance by a Borrower, no authorization or approval
         or other action by, and no notice to or filing with, any governmental
         authority or regulatory body will be required for such borrowing or
         the use of the proceeds of such Advance.

                 (d)      This Agreement has been duly executed and delivered
         by each Borrower. This Agreement is the legal, valid and binding
         obligation of each Borrower enforceable against each Borrower in
         accordance with its terms, except as such enforceability may be
         limited by any applicable bankruptcy, insolvency, reorganization,
         moratorium or similar law affecting creditors' rights generally and by
         general principles of equity. The A Notes of each Borrower are, and
         when executed the B Notes of such Borrower will be, the legal, valid

         Borrower in accordance with their respective terms, except as such
         enforceability may be limited by any applicable bankruptcy,

         respect to any Borrower; provided, however, that this sentence shall
         not be applicable to any adverse change resulting from or arising in
         connection with any event, circumstance or condition (other than those
         listed in clauses (i) through (iv) of this sentence) occurring or

         Banks, there is, as to each Borrower, no pending or, to the knowledge
         of such Borrower, threatened action





                                      -38-
   43
         or proceeding affecting such Borrower or any Subsidiary of such
         Borrower before any court, governmental agency or arbitrator, which
         could reasonably be expected to materially and adversely affect the
         financial condition or operations of such Borrower and its
         Subsidiaries taken as a whole or which purports to affect the
         legality, validity, binding effect or enforceability of this Agreement
         or any Note.

                 (g)      No proceeds of any Advance will be used for any
         purpose or in any manner not permitted by Section 5.02(k).

         credit for the purpose of purchasing or carrying margin stock (within
         the meaning of Regulation U issued by the Board of Governors of the
         Federal Reserve System), and no proceeds of any Advance will be used
         to purchase or carry any such margin stock (other than purchases of
         common stock expressly permitted by Section 5.02(k)) or to extend
         credit to others for the purpose of purchasing or carrying any such
         margin stock. Following the application of the proceeds of each

         represented by such margin stock.

                 (i)      No Borrower is an "investment company" or a company
         "controlled" by an "investment company" within the meaning of the
         Investment Company Act of 1940, as amended.

                 (j)      No Termination Event has occurred or is reasonably
         expected to occur with respect to any Plan for which an Insufficiency
         exists. No Borrower nor any ERISA Affiliate of any Borrower has
         received any notification that any Multiemployer Plan is in
         reorganization or has been terminated, within the meaning of Title IV
         of ERISA, and no Borrower is aware of any reason to expect that any
         Multiemployer Plan is to be in reorganization or to be terminated
         within the meaning of Title IV of ERISA.

                 (k)      As of the date of this Agreement, the United States
         federal income tax returns of each Borrower and the Subsidiaries of
         each Borrower have been examined through the fiscal year ended

         have filed all United States Federal income tax returns and all other
         material domestic tax returns which are required to be filed by them
         and have paid, or provided for the payment before the same become

         any assessment received by any Borrower or any such Subsidiary, other
         than those taxes contested in good faith by appropriate proceedings.
         The charges, accruals





                                      -39-

         each Borrower in respect of taxes are adequate.

                 (l)      No Borrower is a "holding company", or a "subsidiary
         company" of a "holding company", or an "affiliate" of a "holding
         company" or of a "subsidiary company"' of a "holding 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 the Public Filings or as
         otherwise disclosed in writing by a Borrower to the Banks and the
         Agent after the date hereof and approved by the Majority Banks, the
         Borrowers and their respective Subsidiaries are in compliance in all
         material respects with all Environmental Protection Statutes to the
         extent material to their respective operations or financial condition.
         Except as set forth in the Public Filings or as otherwise disclosed in

         accounting principles and set forth in the financial statements
         regarding such Borrower referred to in Section 4.01(e) and delivered
         to each Bank) which are reasonably expected to arise in connection
         with (i) the requirements of Environmental Protection Statutes or (ii)
         any obligation or liability to any Person in connection with any
         Environmental matters (including, without limitation, 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) does not exceed 10% of the
         Consolidated Tangible Net Worth of such Borrower (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).

         Subsidiaries, and all lawful claims which, if unpaid, might become a
         Lien upon any property of it or any of its Subsidiaries, provided
         that no Borrower nor any Subsidiary of a Borrower shall be required
         to pay any such tax, assessment, charge, levy or claim which is being
         contested in good faith and by proper proceedings and with respect to

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

                 (c)      Any Borrower shall fail to perform or observe (i) any

         Business Days after the earlier of the date notice thereof shall have
         been given to such Borrower by the Agent or any Bank or the date such
         Borrower shall have knowledge of such failure, or (ii) any term,
         covenant or agreement contained in this Agreement (other than a term,
         covenant or agreement contained in Section 5.01(b)) or any Note on its
         part to be performed or observed; or

                 (d)      Any Borrower or any Subsidiary of any Borrower shall

                 (e)      Any Borrower or any Subsidiary of any Borrower
         (except any immaterial Subsidiary of such Borrower other than WNG, WEV
         and WFS) 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

         excess of $20,000,000 shall be rendered against any Borrower or any
         Subsidiary of any Borrower (except any immaterial Subsidiary of such
         Borrower other than WEV, WNG and WFS) 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 which a stay of enforcement of such
         judgment or order, by reason of a pending appeal or otherwise, shall
         not be in effect; or

         exist and (ii) the sum (determined as of the date of occurrence of
         such Termination Event) of the Insufficiency of such Plan and the
         Insufficiency of any and all other Plans with respect to which a
         Termination Event shall have occurred and then exist (or in the case
         of a Plan with respect to which a Termination Event described in
         clause (ii) of the definition of Termination Event shall have occurred
         and then exist, the liability related thereto) is equal to or greater
         than $5,000,000; or

                 (h)      Any Borrower or any ERISA Affiliate of any Borrower
         shall have been notified by the sponsor of a Multiemployer Plan that
         it has incurred





                                      -50-
   55
         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 $715,000,000
         in the aggregate or requires payments exceeding $10,000,000 per annum;
         or

                 (i)      Any Borrower or any ERISA Affiliate of any Borrower
         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 Borrowers 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 date hereof by an amount exceeding $5,000,000;

then, and in any such event, the Agent (i) shall at the request, or may with
the consent, of the holders of at least 66-2/3% in principal amount of the A
Notes then outstanding or, if no A Notes are then outstanding, Banks having at
least 66-2/3% of the Commitments, by notice to the Borrowers, declare all of
the Commitments and the obligation of each Bank to make Advances to be
terminated, whereupon all of the Commitments and each such obligation shall
forthwith terminate, and (ii) shall at the request, or may with the consent,
of the holders of at least 66-2/3% in principal amount of the A Notes then
outstanding or if no A Notes are then outstanding, Banks having at least
66-2/3% of the Commitments, or, if no A Notes are then outstanding and all
Commitments have terminated, the holders of at least 66-2/3% in principal
amount of the B Notes then outstanding, by notice to the Borrower as to which
an Event of Default exists (determined as contemplated by the definition herein
of Events of Default), declare the Notes of such Borrower, all interest thereon
and all other amounts payable by such Borrower under this Agreement to be
forthwith due and payable, whereupon such Notes, such interest and 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 each Borrower; provided, however, that in the event of any Event of Default
described in Section 6.01(e), (A)the obligation of each Bank to make Advances
shall automatically be terminated and (B) the Notes, all such interest and all
such 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 each Borrower.

                                   THE AGENT

                 Section 7.01. Authorization and Action.  Each Bank hereby
appoints and authorizes the Agent to take such action as agent on its behalf
and to exercise such powers under this Agreement as are delegated to the Agent
by the terms hereof, together with such powers as are reasonably incidental
thereto.  As to any matters not expressly provided for by this Agreement
(including, without limitation, enforcement or collection of the Notes), the
Agent shall not be required to exercise any discretion or take any action, but
shall be required to act or to refrain from acting (and shall be fully
protected in so acting or refraining from acting) upon the instructions of
holders of at least 66-2/3% in principal amount of the A Notes then outstanding
or, if no A Notes are then outstanding, Banks having at least 66-2/3% of the
Commitments (or, if no A Notes are then outstanding and all Commitments have
terminated, upon the instructions of holders of at least 66-2/3% in principal
amount of the B Notes then outstanding), and such instructions shall be binding
upon all Banks and all holders of Notes; provided, however, that the Agent
shall not be required to take any action which exposes the Agent to personal
liability or which is contrary to any Note, this Agreement or applicable law.
The Agent agrees to give to each Bank prompt notice of each notice given to it
by any Borrower pursuant to the terms of this Agreement.

                 Section 7.02. Agent's Reliance, Etc.  Neither the Agent nor
any of its directors, officers, agents or employees shall be liable for any
action taken or omitted to be taken by it or them under or in connection with
any Note or this Agreement, except for its or their own gross negligence or
willful misconduct.  Without limitation of the generality of the foregoing, the
Agent: (i) may treat the payee of any Note as the holder thereof until the
Agent receives and accepts a Transfer Agreement executed by a Borrower, the
Bank which is the payee of such Note, as assignor, and the assignee in
accordance with the last sentence of Section 8.06(a); (ii) 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; (iii) makes no warranty or
representation to any Bank and shall not be responsible to any Bank for any
statements, warranties or representations (whether written or oral) made in or
in connection with any Note or this Agreement; (iv) shall not have any duty to
ascertain or to inquire as to the performance or observance of any of the
terms, covenants or conditions of any Note or this Agreement on the part of any
Borrower or to inspect the property (including the books and records) of any
Borrower; (v) shall not be responsible to any Bank for the due execution,
legality, validity, enforceability, genuineness, sufficiency or value of any
Note or this Agreement or any other instrument or document furnished pursuant
hereto; and (vi) shall incur no liability under or in respect of any Note or
this Agreement by acting upon any notice, consent,

certificate or other instrument or writing (which may be by telecopier,
telegram, cable or telex) believed by it to be genuine and signed or sent by
the proper party or parties.

                 Section 7.03. Citibank and Affiliates.  With respect to its
Commitments, the Advances made by it and the Notes issued to it, Citibank shall
have the same rights and powers under any Note and this Agreement as any other
Bank and may exercise the same as though it was not the Agent; and the term
"Bank" or "Banks" shall, unless otherwise expressly indicated, include Citibank
in its individual capacity.  Citibank and its affiliates may accept deposits
from, lend money to, act as trustee under indentures of, and generally engage
in any kind of business with, any Borrower, any Subsidiary of any Borrower, any
Person who may do business with or own, directly or indirectly, securities of
any Borrower or any such Subsidiary and any other Person, all as if Citibank
were not the Agent and without any duty to account therefor to the Banks.

                 Section 7.04. Bank Credit Decision.  Each Bank acknowledges
that it has, independently and without reliance upon the Agent or any other
Bank and based on the financial statements referred to in Section 4.01(e) and
such other documents and information as it has deemed appropriate, made its own
credit analysis and decision to enter into this Agreement.  Each Bank also
acknowledges that it will, independently and without reliance upon the
Agent or any other Bank and based on such documents and information as it
shall deem appropriate at the time, continue to make its own credit decisions
in taking or not taking action under any Note or this Agreement.

                 Section 7.05. Indemnification.  The Banks agree to indemnify
the Agent (to the extent not reimbursed by the Borrowers), ratably according to
the respective principal amounts of the A Notes then held by each of them (or
if no A Notes are at the time outstanding or if any A Notes are held by Persons
which are not Banks, ratably according to either (i) the respective amounts of
their Commitments to TWC, or (ii) if all Commitments to TWC have terminated,
the respective amounts of the Commitments to TWC immediately prior to the time
the Commitments to TWC terminated), from and against any and all liabilities,
obligations, losses, damages, penalties, actions, judgments, suits, costs,
expenses or disbursements of any kind or nature whatsoever which may be imposed
on, incurred by, or asserted against the Agent in any way relating to or
arising out of any Note or this Agreement or any action taken or omitted by the
Agent under any Note or this Agreement, provided that no Bank shall be liable
to the Agent for any portion of such liabilities, obligations, losses, damages,
penalties, actions, judgments, suits, costs, expenses or disbursements
resulting from the Agent's gross negligence or willful misconduct.  Without
limitation of the foregoing, each Bank agrees to reimburse the Agent promptly
upon demand for its ratable share of any out-of-pocket expenses (including
counsel fees) incurred by the 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





                                      -53-
   58
rights or responsibilities under, any Note or this Agreement to the extent that
the Agent is not reimbursed for such expenses by the Borrowers.

                 Section 7.06. Successor Agent.  The Agent may resign at any 
time as 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. Upon any such resignation or removal, the Majority
Banks shall have the right to appoint, with the consent of TWC (which consent
shall not be unreasonably withheld), a successor Agent from among the Banks. 
If no successor Agent shall have been so appointed by the Majority Banks with
such consent, and shall have accepted such appointment, within 30 days after
the retiring Agent's giving of notice of resignation or the Majority Banks'
removal of the retiring Agent, then the retiring Agent may, on behalf of the
Banks, appoint a successor 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 under this Agreement by a
successor Agent, such successor Agent shall thereupon succeed to and become
vested with all the rights, powers, privileges and duties of the retiring Agent
and shall function as the Agent under this Agreement, and the retiring Agent
shall be discharged from its duties and obligations as Agent under this
Agreement.  After any retiring Agent's resignation or removal hereunder as
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 under this
Agreement.


                                  ARTICLE VIII

                                 MISCELLANEOUS

                 Section 8.01. Amendments, Etc.  No amendment or waiver of any
provision of any Note or 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 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, do any of the following: (a)
waive any of the conditions specified in Article III, (b) increase the
Commitments of the Banks or subject the Banks to any additional obligations,
(c) reduce the principal of, or interest on, the Notes or any fees or other
amounts payable hereunder, (d) postpone any date fixed for any payment of

hereunder, (e) take any action which requires the signing of all the Banks
pursuant to the terms of this Agreement, (f) change the percentage of the
Commitments or of the aggregate unpaid principal amount of the A Notes or B
Notes, or the number of Banks, which shall be





                                      -54-
   59
required for the Banks or any of them to take any action under this Agreement,
or (g) amend this Section 8.01; and provided, further, that no amendment,
waiver or consent shall, unless in writing and signed by the Agent in addition
to the Banks required above to take such action, affect the rights or duties of
the Agent under any Note or this Agreement.

                 Section 8.02. Notices, Etc.  All notices and other
communications provided for hereunder shall be in writing (including telecopy,
telegraphic, telex or cable communication) and mailed, telecopied, telegraphed,
telexed, cabled or delivered, if to any Bank, as specified opposite its name on

result of a payment pursuant to Section 2.10 or 2.12 or acceleration of the

result of any such purchase or any Conversion, such Borrower shall, upon demand

additional losses, costs or expenses which it may reasonably incur as a result
of any such payment, purchase or Conversion, including, without limitation, any

                 (c)      Each Borrower agrees, to the fullest extent permitted
by law, to indemnify and hold harmless the Agent, the Arranger and each Bank
and each of their respective directors, officers, employees and agents from and
against any and all claims, damages, liabilities and out-of-pocket expenses

party thereto, arising out of, related to or in connection with this Agreement

Advances are applied (other than any such claim, damage, liability or expense

   61
a Borrower due and payable pursuant to the provisions of Section 6.01, each
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 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 Notes held by such Bank,
irrespective of whether or not such Bank shall have made any demand under this
Agreement or such Notes and although such obligations may be unmatured.  Each
Bank agrees promptly to notify such Borrower after such set-off and application
made by such Bank, provided that the failure to give such notice shall not
affect the validity of such set-off and application.  The rights of each Bank
under this Section are in addition to other rights and remedies (including,
without limitation, other rights of set-off) which such Bank may have.

                 Section 8.06.    Binding Effect; Transfers.    (a) This
Agreement shall become effective when it shall have been executed by the
Borrowers and the Agent and when each Bank listed on the signature pages hereof
has delivered an executed counterpart hereof to the Agent, has sent to the
Agent a facsimile copy of its signature hereon or has notified the Agent that
such Bank has executed this Agreement and thereafter shall be binding upon and
inure to the benefit of the Borrowers, the Agent and each Bank and their
respective successors and assigns, except that the Borrowers shall not have the
right to assign any of their respective rights hereunder or any interest herein
without the prior written consent of the Banks.  Each Bank may assign to one or
more banks, financial institutions or government entities all or any part of,
or may grant participations to one or more banks, financial institutions or
government entities in or to all or any part of, any Advance or Advances owing
to such Bank, any Note or Notes held by such Bank and all or any portion of
such Bank's Commitments, and to the extent of any such assignment or
participation (unless otherwise stated therein) the assignee or purchaser of
such assignment or participation shall, to the fullest extent permitted by law,
have the same rights and benefits hereunder and under such Note or Notes as it
would have if it were such Bank hereunder, provided that, except in the case
of an assignment meeting the requirements of the next sentence hereof, (1) such
Bank's obligations under this Agreement, including, without limitation, its
Commitments to the Borrowers hereunder, shall remain unchanged, such Bank shall
remain responsible for the performance thereof, such Bank shall remain the
holder of any such Note or Notes for all purposes under this Agreement, and the
Borrowers, the other Banks and the Agent shall continue to deal solely with and
directly with such Bank in connection with such Bank's rights and obligations
under this Agreement; and (2) no Bank shall assign or grant a participation
that conveys to the assignee or participant the right to vote or consent under
this Agreement, other than the right to vote upon or consent to (i) any
increase in the amount of any Commitment of such Bank; (ii) any reduction of
the principal amount of, or interest to be paid on, such Bank's Advance or
Advances or Note or Notes; (iii) any reduction of any fee or other amount
payable hereunder to such





                                      -57-
   62
Bank; or (iv) any postponement of any date fixed for any payment of principal
of, or interest on, such Bank's Advance or Advances or Note or Notes or any fee
or other amount payable hereunder to such Bank.

         If (I) the assignee of any Bank either (1) is another Bank or (2) is
approved in writing by the Agent and the Borrowers or (3) is approved in
writing by the Agent and either an Event of Default exists or the Borrowers
have relinquished the right to approve the assignment pursuant to Section
8.06(b), and (II) such assignee assumes all or any portion (which portion shall
be a constant, and not a varying, percentage, and the amount of the Commitment
to TWC assigned, whether all or a portion, shall be in a minimum amount of
$5,000,000) of each of the Commitments of such assigning Bank to the respective
Borrowers (either all of each such Commitment shall be assigned or the
percentage portion of each such Commitment assigned shall be the same as to
each Borrower) by executing a document in the form of Exhibit H (or with such
changes thereto as have been approved in writing by the Agent in its sole
discretion as evidenced by its execution thereof duly executed by the Agent,
the Borrowers (unless an Event of Default exists or the Borrowers have
relinquished the right to approve the assignment pursuant to Section 8.06(b)),
such assigning Bank and such assignee and delivered to the Agent ("Transfer
Agreement"), then upon such delivery, (i) such assigning Bank shall be released
from its obligations under this Agreement with respect to all or such portion,
as the case may be, of its Commitments, (ii) such assignee shall become
obligated for all or such portion, as the case may be, of such Commitments and
all other obligations of such assigning Bank hereunder with respect to or
arising as a result of all or such portion, as the case may be, of such
Commitments, (iii) such assignee shall be assigned the right to vote or consent
under this Agreement, to the extent of all or such portion, as the case may be,
of such Commitments, (iv) each Borrower shall deliver, in replacement of the A
Note of such Borrower to such assigning Bank then outstanding (a) to such
assignee, a new A Note of such Borrower in the amount of the Commitment of such
assigning Bank to such Borrower which is being so assumed by such assignee
plus, in the case of any assignee which is already a Bank hereunder, the amount
of such assignee's Commitment to such Borrower immediately prior to such
assignment (any such assignee which is already a Bank hereunder agrees to
cancel and return to such Borrower, with reasonable promptness following the
delivery of such new A Note, the A Note being replaced thereby), (b) to such
assigning Bank, a new A Note in the amount of the balance, if any, of the
Commitment of such assigning Bank to such Borrower (without giving effect to
any B Reduction) retained by such assigning Bank (and such assigning Bank
agrees to cancel and return to such Borrower, with reasonable promptness
following delivery of such new A Notes, the A Note being replaced thereby), and
(c) to the Agent, photocopies of such new A Notes, (v) if such assignment is of
all of such assigning Bank's Commitments to the Borrowers, all of the
outstanding A Advances made by such assigning Bank shall be transferred to such
assignee, (vi) if such assignment is not of all of such Commitments, a part of
each A Advance to each Borrower equal to the





                                      -58-
   63
amount of such Advance multiplied by a fraction, the numerator of which is the
amount of such portion of such assigning Bank's Commitment to such Borrower so
assumed and the denominator of which is the amount of the Commitment of such
assigning Bank to such Borrower (without giving effect to any B Reduction)
immediately prior to such assumption, shall be transferred to such assignee and
evidenced by such assignee's A Note from such Borrower, and the balance of such
A Advance shall be evidenced by such assigning Bank's new A Note from such
Borrower delivered pursuant to clause (iv)(b) of this sentence, (vii) if such
assignee is not a "Bank" hereunder prior to such assignment, such assignee
shall become a party to this Agreement as a Bank and shall be deemed to be a
"Bank" hereunder, and the amount of all or such portion, as the case may be, of
the Commitments to the respective Borrowers so assumed shall be deemed to be
the amount set opposite such assignee's name on the signature pages hereof for
purposes of this Agreement, and (viii) if such assignee is not a Bank hereunder
prior to such assignment, such assignee shall be deemed to have specified the
offices of such assignee named in the respective Transfer Agreement as its
"Domestic Lending Office" and "Eurodollar Lending Office" for all purposes of
this Agreement and to have specified for purposes of Section 8.02 the notice
information set forth in such Transfer Agreement; and the Agent shall promptly
after execution of any Transfer Agreement by the Agent and the other parties
thereto notify the Bank's of the parties to such Transfer Agreement and the
amounts of the assigning Bank's Commitments assumed thereby.

         (b)     If the Borrowers do not consent to a proposed assignment by a
Bank pursuant to the last sentence of Section 8.06(a), TWC may, within 15 days
of its receipt of a request that it consent to such assignment nominate by
notice to the Agent and such Bank a bank which, if it is not a Bank, is
acceptable to the Agent, and which unconditionally offers in writing (with a
copy to the Agent) to purchase and assume, to the extent of the amount of such
proposed assignment, in accordance with all of the provisions of the last
sentence of Section 8.06(a) (including execution of an appropriate Transfer
Agreement), all of such Bank's rights and obligations (including, without
limitation, its Commitments) hereunder and interest in the Advances owing to
such Bank and the Notes held by such Bank without recourse at par plus interest
accrued thereon to the date of such purchase on a date therein specified (not
less than three nor greater than five Business Days after such nomination).
Such Bank at its option may elect to accept or not accept such purchase offer.
If a Bank accepts such an offer and the bank first nominated by TWC pursuant to
this Section 8.06(b) fails to purchase such rights and interest on such
specified date in accordance with the terms of such offer, TWC may, within 15
days of such failure, repeat the process contemplated by the first sentence of
this Section 8.06(b) by nominating another bank for purposes of this Section
8.06(b) by notice to the Agent and such Bank.  If TWC does not so nominate such
a bank within 15 days of its receipt of such request that it consent to such
assignment or if TWC fails to nominate another bank following such a failure to
purchase or if such second nominated bank fails to purchase in accordance with
the





                                      -59-
   64
terms of an offer complying with the first sentence of this Section 8.06(b),
the Borrowers shall be deemed to have relinquished their right to consent to
such assignment.  If such Bank elects to not accept such a purchase offer under
this Section 8.06(b) as to a particular proposed assignment, the Borrowers
shall not be deemed to have relinquished their right to consent to such
assignment.

         (c)     The Borrowers agree to promptly execute the Transfer Agreement
pertaining to any assignment as to which approval by the Borrowers of the
assignee is not required by clause (1) of the last sentence of Section 8.06(a).

         (d)     Any Bank may assign, as collateral or otherwise, any of its
rights (including, without limitation, rights to payments of principal of
and/or interest on the Notes) under this Agreement or an), of the Notes to any
Federal Reserve Bank without notice to or consent of any Borrower or the Agent.

                 Section 8.07. 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 8.08. Interest.  It is the intention of the parties
hereto that the Agent and each Bank shall conform strictly to usury laws
applicable to it, if any.  Accordingly, if the transactions with the Agent or
any Bank, contemplated hereby would be usurious under applicable law, then, in
that event, notwithstanding anything to the contrary in the Notes, this
Agreement or any other agreement entered into in connection with or as security
for this Agreement or the Notes, 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 or such Bank,
as the case may be, under the Notes, this Agreement or under any other
agreement entered into in connection with or as security for this Agreement or
the Notes shall under no circumstances exceed the maximum amount allowed by
such applicable law and any excess shall be cancelled automatically and, if
theretofore paid, shall at the option of the Agent or such Bank, as the case
may be, be credited by the Agent or such Bank, as the case may be, on the
principal amount of the obligations owed to the Agent or such Bank, as the
case may be, by the appropriate Borrower or refunded by the Agent or such
Bank, as the case may be, to the appropriate Borrower, and (ii) in the event
that the maturity of any Note or other obligation payable to the 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 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 or such Bank, as the case may be, provided for
in this Agreement or otherwise shall be cancelled automatically as of the date
of such acceleration or prepayment and, if theretofore paid, shall, at the
option of the Agent or such Bank, as the case may be, be credited by the Agent
or such Bank, as the case may be, on the principal amount of the obligations





                                      -60-
   65
owed to the Agent or such Bank, as the case may be, by the appropriate Borrower
or refunded by the Agent or such Bank, as the case may be, to the appropriate
Borrower.

                 Section 8.09. 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.

                 Section 8.10. Survival of Agreements, Representations and
Warranties, Etc.  All warranties, representations and covenants made by any
Borrower or any 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 shall survive the issuance and delivery
of the Notes and the making of the Advances regardless of any investigation.
The indemnities and other payment obligations of each Borrower contained in
this Agreement, and the indemnities by the Banks in favor of the Agent and its
officers, directors, employees and agents, will survive the repayment of the
Advances and the termination of this Agreement.

                 Section 8.11. Borrowers' Right to Apply Deposits.  In the
event that any Bank is placed in receivership or enters a similar proceeding,
each Borrower may, to the full extent permitted by law, make any payment due to
such Bank hereunder, to the extent of finally collected unrestricted deposits
of such Borrower in U.S. dollars held by such Bank, by giving notice to the
Agent and such Bank directing such Bank to apply such deposits to such
indebtedness.  If the amount of such deposits is insufficient to pay such
indebtedness then due and owing in full, such Borrower shall pay the balance of
such insufficiency in accordance with this Agreement.

                 Section 8.12. Confidentiality.  Each Bank agrees that it will
use best efforts, to the extent not inconsistent with practical business
requirements, not to disclose without the prior consent of TWC -(other than to
employees, auditors, accountants, counsel or other professional advisors of the
Agent or any Bank) any information with respect to the Borrowers or their
Subsidiaries which is furnished pursuant to this Agreement and which (i) the
Borrowers in good faith consider to be confidential and (ii) is either clearly
marked confidential or is designated by the Borrowers to the Agent or the Banks
in writing as confidential, provided that any Bank may disclose any such
information (a) as has become generally available to the public, (b) as may be
required or appropriate in any report, statement or testimony submitted to or
required by any municipal, state or Federal regulatory body having or claiming
to have jurisdiction over such Bank or submitted to or required by the Board of
Governors of the Federal Reserve System or the Federal Deposit Insurance
Corporation or similar organizations (whether in the United States or
elsewhere) or their successors, (c)  as may be required or appropriate in
response to any summons or subpoena in connection with any litigation, (d) in
order to comply with any law, order, regulation





                                      -61-
   66
or ruling applicable to such Bank, (e) to the prospective transferee in
connection with any contemplated transfer of any of the Notes or any interest
therein by such Bank, 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 8.12, and provided
further that if the contemplated transfer is a grant of a participation in a
Note (and not an assignment), no such information shall be authorized to be
delivered to such participant pursuant to this clause (e) except (i) such
information delivered pursuant to Section 4.01(e) or Section 5.01(b) (other
than paragraph (iv) thereof), and (ii) if prior notice of the delivery thereof
is given to TWC, such information as may be required by law or regulation to be
delivered, (f) in connection with the exercise of any remedy by such Bank
pertaining to this Agreement, any of the Notes or any other document delivered
in connection herewith, (g) in connection with any litigation involving such
Bank pertaining to this Agreement, any of the Notes or any other document
delivered in connection herewith, (h) to any Bank or the Agent, or (i) to any
affiliate of any Bank, provided that such affiliate executes an agreement with
or for the benefit of the Borrowers containing provisions substantially
identical to those contained in this Section 8.12.

                 Section 8.13. WAIVER OF JURY TRIAL.  THE BORROWERS,
THE AGENT, 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 NOTE OR ANY OF THE TRANSACTIONS CONTEMPLATED HEREBY.

                 IN WITNESS WHEREOF, the parties hereto have caused this
Agreement to be executed by their respective officers thereunto duly
authorized, as of the date first above written.
