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. -18- 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.

(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. -28- 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. -29- 34 (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.

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.

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.
