2.6 Making Revolving Credit Loans and Swing Loans; Swing Notes; Presumptions by the Agent.

2.6.1 Making Revolving Credit Loans.

The Agent shall, promptly after receipt by it of a Loan Request pursuant to Section 2.5 [Revolving Credit Loan Requests], notify the Banks of its receipt of such Loan Request specifying: (i) the proposed Borrowing Date and the time and method of disbursement of the Revolving Credit Loans requested thereby; (ii) the amount and type of each such Revolving Credit Loan and the applicable Interest Period (if any); and (iii) the apportionment among the Banks of such Revolving Credit Loans as determined by the Agent in accordance with Section 2.2 [Nature of Banks' Obligations]. Each Bank shall remit the principal amount of each Revolving Credit Loan to the Agent such that the Agent is able to, and the Agent shall, to the extent the Banks have made funds available to it for such purpose and subject to Section 7.2 [Each Additional Loan], fund such Revolving Credit Loans to the Borrower in U.S. Dollars and immediately available funds at the Principal Office prior to 2:00 p.m., Pittsburgh time, on the applicable Borrowing Date, provided that if any Bank fails to remit such funds to the Agent in a timely manner, the Agent may elect in its sole discretion to fund with its own funds the Revolving Credit Loans of such Bank on such Borrowing Date, and such Bank shall be subject to the repayment obligation in Section 2.6.3 [Presumptions by the Agent].

2.6.2 Making Swing Loans.

So long as PNC Bank elects to make Swing Loans, PNC Bank shall, after receipt by it of a Swing Loan Request pursuant to Section 2.5.2 [Swing Loan Request], fund such Swing Loan to the Borrower in U.S. Dollars and immediately available funds at the Principal Office prior to 4:00 p.m. Pittsburgh time on the Borrowing Date.

2.6.3 Presumptions by the Agent.

Unless the Agent shall have received notice from a Bank prior to the proposed date of any Loan that such Bank will not make available to the Agent such Bank's share of such Loan, the Agent may assume that such Bank has made such share available on such date in accordance with Section 2.6.1 [Making Revolving Credit Loans] and may, in reliance upon such assumption, make available to the Borrower a corresponding amount. In such event, if a Bank has not in fact made its share of the applicable Loan available to the Agent, then the applicable Bank and the Borrower severally agree to pay to the Agent forthwith on demand such corresponding amount with interest thereon, for each day from and including the date such amount is made available to the Borrower to but excluding the date of payment to the Agent, at (i) in the case of a payment to be made by such Bank, the greater of the Federal Funds Effective Rate and a rate determined by the Agent in accordance with banking industry rules on interbank compensation and (ii) in the case of a payment to be made by the Borrower, the interest rate applicable to Loans under the Base Rate Option or LIBOR Rate Option, as applicable. If such Bank pays its share of the applicable Loan to the Agent, then the amount so paid shall constitute such Bank's Loan. Any payment by the Borrower shall be without prejudice to any claim the Borrower may have against a Bank that shall have failed to make such payment to the Agent.

2.9.1 Issuance of Letters of Credit.

On the Closing Date, the outstanding Letters of Credit previously issued by PNC Bank as an "Issuing Bank" under the Existing Credit Agreement that are set forth on Schedule 2.9.1 (the "Existing Letters of Credit") will automatically, without any action on the part of any Person, be deemed to be Letters of Credit issued hereunder for the account of the Borrower for all purposes of this Agreement and the other Loan Documents. In addition, Borrower may request the issuance of a letter of credit (each a "Letter of Credit") on behalf of itself or another Loan Party, or the amendment or extension of an existing Letter of Credit, by delivering or having such other Loan Party deliver to the Issuing Bank (with a copy to the Agent) a completed application and agreement for letters of credit, or request for such amendment or extension, as applicable, in such form as the Issuing Bank may specify from time to time by no later than 10:00 a.m., Pittsburgh time, at least five (5) Business Days, or such shorter period as may be agreed to by the Agent, in advance of the proposed date of issuance. Each Letter of Credit shall be a Standby Letter of Credit. Promptly after receipt of any letter of credit application, the Issuing Bank shall confirm with the Agent (by telephone or in writing) that the Agent has received a copy of such Letter of Credit application and if not, such Issuing Bank will provide Agent with a copy thereof. Unless the Issuing Bank has received notice from any Bank, Agent or any Loan Party, at least one day prior to the requested date of issuance, amendment or extension of the applicable Letter of Credit, that one or more applicable conditions in Section 7 [Conditions of Lending and Issuance of Letter of Credit] is not satisfied, then, so long as there is no Event of Default or Potential Default, subject to compliance with all of the terms and conditions set forth in this Agreement, any Letter of Credit may be automatically renewable if such selection is made on the application for such Letter of Credit. Subject to the terms and conditions hereof and in reliance on the agreements of the other Banks set forth in this Section 2.9, the Issuing Bank or any of the Issuing Bank's Affiliates will issue a Letter of Credit or renew an existing Letter of Credit, provided that each Letter of Credit shall (A) have a

39

Table of Contents

maximum maturity of twelve (12) months from the date of issuance, and (B) in no event expire later than one (1) year beyond the expiration date, provided that any Letter of Credit scheduled to expire after the Expiration Date is subject to the requirements in Section 2.9.10 [Cash Collateral Prior to the Expiration Date]. In no event shall (i) the Letter of Credit Obligations exceed, at any one time, $15,000,000 (the "Letter of Credit Sublimit") or (ii) the Revolving Facility Usage exceed, at any one time, the Revolving Credit Commitments or the Borrowing Base. Each request by the Borrower for the issuance, amendment or extension of a Letter of Credit shall be deemed to be a representation by the Borrower that it shall be in compliance with the preceding sentence and with Section 7.2 [Each Additional Loan or Letter of Credit] after giving effect to the requested issuance, amendment or extension of such Letter of Credit. Promptly after its delivery of any Letter of Credit or any amendment to a Letter of Credit to the beneficiary thereof, the applicable Issuing Bank will also deliver to Borrower and Agent a true and complete copy of such Letter of Credit or amendment.

2.9.2 Letter of Credit Fees.

The Borrower shall pay (i) to the Agent for the ratable account of the Banks a fee (the "Letter of Credit Fee") equal to the percentage per annum equal to the Revolving Credit LIBOR Rate Option, and (ii) if PNC ceases to be the only Bank holding a Revolving Credit Commitment, to the Issuing Bank for its own account a fronting fee equal to 0.25% per annum (computed on the basis of a year of 360 days and actual days elapsed), which fees shall be computed on the daily average Letter of Credit Obligations and shall be payable quarterly in arrears commencing with the last Business Day of each June, September, December and March following issuance of each Letter of Credit and on the Expiration Date. The Borrower shall also pay to the Issuing Bank for the Issuing Bank's sole account the Issuing Bank's then in effect customary fees and administrative expenses payable with respect to the Letters of Credit as the Issuing Bank may generally charge or incur from time to time in connection with the issuance, maintenance, modification (if any), assignment or transfer (if any), negotiation, and administration of Letters of Credit.

2.9.3 Disbursements, Reimbursement.

2.9.3.1    Immediately upon the issuance of each Letter of Credit, each Bank shall be deemed to, and hereby irrevocably and unconditionally agrees to, purchase from the Issuing Bank a participation in such Letter of Credit (including the Existing Letters of Credit) and each drawing thereunder in an amount equal to such Bank's Ratable Share of the maximum amount available to be drawn under such Letter of Credit and the amount of such drawing, respectively.

2.9.3.2    In the event of any request for a drawing under a Letter of Credit by the beneficiary or transferee thereof, the Issuing Bank will promptly notify the Borrower and the Agent thereof. Provided that it shall have received such notice, the Borrower shall reimburse (such obligation to reimburse the Issuing Bank shall sometimes be referred to as a "Reimbursement Obligation") the Issuing Bank prior to 12:00 noon, Pittsburgh time on each date that an amount is paid by the Issuing Bank under any Letter of Credit (each such date, a "Drawing Date") by paying to the Agent for the account of the Issuing Bank in an amount equal to the amount so paid by the Issuing Bank. In the event the Borrower

40

Table of Contents

fails to reimburse the Issuing Bank for the full amount of any drawing under any Letter of Credit by 12:00 noon, Pittsburgh time, on the Drawing Date, the Agent will promptly notify each Bank thereof, and the Borrower shall be deemed to have requested that Revolving Credit Loans be made by the Banks under the Base Rate Option to be disbursed on the Drawing Date under such Letter of Credit, subject to the amount of the unutilized portion of the Revolving Credit Commitment and subject to the conditions set forth in Section 7.2 [Each Additional Loan] other than any notice requirements. Any notice given by the Agent or Issuing Bank pursuant to this Section 2.9.3.2 may be oral if immediately confirmed in writing; provided that the lack of such an immediate confirmation shall not affect the conclusiveness or binding effect of such notice.

2.9.3.3    Each Bank shall upon any notice pursuant to Section 2.9.3.2 make available to the Agent for the account of the Issuing Bank an amount in immediately available funds equal to its Ratable Share of the amount of the drawing, whereupon the participating Banks shall (subject to Section 2.9.3.4) each be deemed to have made a Revolving Credit Loan under the Base Rate Option to the Borrower in that amount. If any Bank so notified fails to make available to the Agent for the account of the Issuing Bank the amount of such Bank's Ratable Share of such amount by no later than 2:00 p.m., Pittsburgh time on the Drawing Date, then interest shall accrue on such Bank's obligation to make such payment, from the Drawing Date to the date on which such Bank makes such payment (i) at a rate per annum equal to the Federal Funds Effective Rate during the first three days following the Drawing Date and (ii) at a rate per annum equal to the rate applicable to Loans under the Revolving Credit Base Rate Option on and after the fourth day following the Drawing Date. The Agent and the Issuing Bank will promptly give notice of the occurrence of the Drawing Date, but failure of the Agent or Issuing Bank to give any such notice on the Drawing Date or in sufficient time to enable any Bank to effect such payment on such date shall not relieve such Bank from its obligation under this Section 2.9.3.3.

2.9.3.4    With respect to any unreimbursed drawing that is not converted into Revolving Credit Loans under the Base Rate Option to the Borrower in whole or in part as contemplated by Section 2.9.3.2, because of the Borrower's failure to satisfy the conditions set forth in Section 7.2 [Each Additional Loan] other than any notice requirements or for any other reason, the Borrower shall be deemed to have incurred from the Issuing Bank a borrowing (each a "Letter of Credit Borrowing") in the amount of such drawing. Such Letter of Credit Borrowing shall be due and payable on demand (together with interest) and shall bear interest at the rate per annum applicable to the Revolving Credit Loans under the Base Rate Option. Each Bank's payment to the Agent on behalf of the Issuing Bank pursuant to Section 2.9.3.3 shall be deemed to be a payment in respect of its participation in such Letter of Credit Borrowing and shall constitute a "Participation Advance" from such Bank in satisfaction of its participation obligation under this Section 2.9.3.

2.9.4 Repayment of Participation Advances.

2.9.4.1    Upon (and only upon) receipt by the Agent for the account of the Issuing Bank of immediately available funds from the Borrower (i) in reimbursement of any

41

Table of Contents

payment made by the Agent under the Letter of Credit with respect to which any Bank has made a Participation Advance to the Agent, or (ii) in payment of interest on such a payment made by the Issuing Bank under such a Letter of Credit, the Agent on behalf of the Issuing Bank will pay to each Bank, in the same funds as those received by the Agent, the amount of such Bank's Ratable Share of such funds, except the Agent shall retain for the account of the Issuing Bank the amount of the Ratable Share of such funds of any Bank that did not make a Participation Advance in respect of such payment by Issuing Bank.

2.9.4.2    If the Agent is required at any time to return to any Loan Party, or to a trustee, receiver, liquidator, custodian, or any official in any Insolvency Proceeding, any portion of the payments made by any Loan Party to the Agent for the account of the Issuing Bank pursuant to Section 2.9.4.1 in reimbursement of a payment made under the Letter of Credit or interest or fee thereon, each Bank shall, on demand of the Agent, forthwith return to the Agent for the account of the Issuing Bank the amount of its Ratable Share of any amounts so returned by the Agent plus interest thereon from the date such demand is made to the date such amounts are returned by such Bank to the Agent, at a rate per annum equal to the Federal Funds Effective Rate in effect from time to time.

2.9.5 Documentation.

Each Loan Party agrees to be bound by the terms of the Issuing Bank's application and agreement for letters of credit and the Issuing Bank's written regulations and customary practices relating to letters of credit, though such interpretation may be different from such Loan Party's own. In the event of a conflict between such application or agreement and this Agreement, this Agreement shall govern. It is understood and agreed that, except in the case of gross negligence or willful misconduct, the Issuing Bank shall not be liable for any error, negligence and/or mistakes, whether of omission or commission, in following any Loan Party's instructions or those contained in the Letters of Credit or any modifications, amendments or supplements thereto.

2.9.6 Determinations to Honor Drawing Requests.

In determining whether to honor any request for drawing under any Letter of Credit by the beneficiary thereof, the Issuing Bank shall be responsible only to determine that the documents and certificates required to be delivered under such Letter of Credit have been delivered and that they comply on their face with the requirements of such Letter of Credit.

2.9.7 Nature of Participation and Reimbursement Obligations.

(a)all or any part of the outstanding Swing Loans and Letter of Credit Obligations of such Defaulting Bank shall be reallocated among the non-Defaulting Banks in accordance with their respective Ratable Shares but only to the extent that (x) the Revolving Facility Usage does not exceed the total of all non-Defaulting Bank's Revolving Credit Commitments, and (y) no Potential Default or Event of Default has occurred and is continuing at such time;

46

Table of Contents

(b) if the reallocation described in clause (A) above cannot, or can only partially, be effected, the Borrower shall within one Business Day following notice by the Agent (x) first, prepay such outstanding Swing Loans, and (y) second, Cash Collateralize for the benefit of the Issuing Bank the Borrower's obligations corresponding to such Defaulting Bank's Letter of Credit Obligations (after giving effect to any partial reallocation pursuant to clause (a) above) in a deposit account held at the Agent for so long as such Letter of Credit Obligations are outstanding;

(d)if the Letter of Credit Obligations of the non-Defaulting Banks are reallocated pursuant to clause (a) above, then the fees that would otherwise have been payable to the Defaulting Bank pursuant to Section 2.9.2 [Letter of Credit Fees] shall be paid to the non-Defaulting Banks adjusted in accordance with such reallocation; and

(e)if all or any portion of such Defaulting Bank's Letter of Credit Obligations are neither reallocated nor Cash Collateralized pursuant to clause (a) or (b) above, then, without prejudice to any rights or remedies of the Issuing Bank or any other Bank hereunder, all Letter of Credit Fees payable under Section 2.9.2 with respect to such Defaulting Bank's Letter of Credit Obligations shall be payable to the Issuing Bank (and not to such Defaulting Bank) until and to the extent that such Letter of Credit Obligations are reallocated and/or Cash Collateralized; and

(iv)    PNC shall not be required to fund any Swing Loans and the Issuing Bank shall not be required to issue, amend or increase any Letter of Credit, unless such Issuing Bank is satisfied that the related exposure and the Defaulting Bank's then outstanding Letter of Credit Obligations will be 100% covered by the Revolving Credit Commitments of the non-Defaulting Banks and/or Cash Collateral will be provided by the Borrower in accordance with Section 2.10(iii), and participating interests in any newly made Swing Loan or any newly issued or increased Letter of Credit shall be allocated among non-Defaulting Banks in a manner consistent with Section 2.10(iii)(a) (and such Defaulting Bank shall not participate therein).

If (i) a Bankruptcy Event with respect to a parent company of any Bank shall occur following the date hereof and for so long as such event shall continue, or (ii) PNC or the Issuing Bank has a good faith belief that any Bank has defaulted in fulfilling its obligations under one or more other agreements in which such Bank commits to extend credit, PNC shall not be required to fund any Swing Loan and the Issuing Bank shall not be required to issue, amend or increase any Letter of Credit, unless PNC or the Issuing Bank, as the case may be, shall have entered into arrangements with the Borrower or such Bank, satisfactory to PNC or the Issuing Bank, as the case may be, to defease any risk to it in respect of such Bank hereunder.

In the event that the Agent, the Borrower, PNC and the Issuing Bank agree in writing that a Defaulting Bank has adequately remedied all matters that caused such Bank to be a Defaulting

47

4. INTEREST RATES

4.1 Interest Rate Options.

The Borrower shall pay interest in respect of the outstanding unpaid principal amount of the Loans as selected by it from the Base Rate Option or LIBOR-Rate Option set forth below applicable to the Loans (provided that only the Base Rate Option shall apply to the Swing Loans), it being understood that, subject to the provisions of this Agreement, the Borrower may select different Interest Rate Options and different Interest Periods to apply simultaneously to the Loans comprising different Borrowing Tranches and may convert to or renew one or more Interest Rate Options with respect to all or any portion of the Loans comprising any Borrowing Tranche, provided that there shall not be at any one time outstanding more than three (3) Borrowing Tranches in the aggregate among all of the Loans and provided further that if an Event of Default or Potential Default exists and is continuing, the Borrower may not request, convert to, or renew the LIBOR Rate Option for any Loans and the Required Banks may demand that all existing Borrowing Tranches bearing interest under the LIBOR Rate Option shall be converted immediately to the Base Rate Option, subject to the obligation of the Borrower to pay any indemnity under Section 2.9.8 [Indemnity] in connection with such conversion. If at any

49

Table of Contents

time the designated rate applicable to any Loan made by any Bank exceeds such Bank's highest lawful rate, the rate of interest on such Bank's Loan shall be limited to such Bank's highest lawful rate.

4.1.1 Revolving Credit Interest Rate Options.

The Borrower shall have the right to select from the following Interest Rate Options applicable to the Revolving Credit Loans (subject to the provisions above regarding Swing Loans):

(i)    Revolving Credit Base Rate Option: A fluctuating rate per annum (computed on the basis of a year of 365 or 366 days, as the case may be, and actual days elapsed) equal to the Base Rate plus 1.75%, such interest rate to change automatically from time to time effective as of the effective date of each change in the Base Rate; or

(ii)    Revolving Credit LIBOR-Rate Option: A rate per annum (computed on the basis of a year of 360 days and actual days elapsed) equal to the LIBOR-Rate plus 2.75%.

Subject to Section 4.3 [Interest After Default], only the Base Rate Option applicable to Revolving Credit Loans shall apply to the Swing Loans.

4.1.2 Intentionally Omitted.

4.1.3 Rate Quotations.

The Borrower may call the Agent on or before the date on which a Loan Request is to be delivered to receive an indication of the rates then in effect, but it is acknowledged that such projection shall not be binding on the Agent or the Banks nor affect the rate of interest which thereafter is actually in effect when the election is made.

4.2 Interest Periods.

At any time when the Borrower shall select, convert to or renew a LIBOR-Rate Option, the Borrower shall notify the Agent thereof at least three (3) Business Days prior to the effective date of such LIBOR-Rate Option by delivering a Loan Request. The notice shall specify an Interest Period during which such Interest Rate Option shall apply. Notwithstanding the preceding sentence, the following provisions shall apply to any selection of, renewal of, or conversion to a LIBOR-Rate Option:

4.2.1 Amount of Borrowing Tranche.

each Borrowing Tranche of LIBOR-Rate Loans shall be in integral multiples of $500,000 and not less than $1,000,000; and

50

Table of Contents

4.2.2 Renewals.

in the case of the renewal of a LIBOR-Rate Option at the end of an Interest Period, the first day of the new Interest Period shall be the last day of the preceding Interest Period, without duplication in payment of interest for such day.

4.3 Interest After Default.

To the extent permitted by Law, upon the occurrence of an Event of Default and until such time such Event of Default shall have been cured or waived, at the discretion of the Agent or upon written demand by the Required Banks to the Agent:

4.3.1 Letter of Credit Fees, Interest Rate.

the Letter of Credit Fees and the rate of interest for each Loan otherwise applicable pursuant to Section 2.9.2 [Letter of Credit Fees] or Section 4.1 [Interest Rate Options], respectively, shall be increased by 2.0% per annum; and

4.3.2 Other Obligations.

each other Obligation hereunder if not paid when due shall bear interest at a rate per annum equal to the sum of the rate of interest applicable under the Revolving Credit Base Rate Option plus an additional 2.0% per annum from the time such Obligation becomes due and payable and until it is paid in full.

4.3.3 Acknowledgment.

The Borrower acknowledges that the increase in rates referred to in this Section 4.3 reflects, among other things, the fact that such Loans or other amounts have become a substantially greater risk given their default status and that the Banks are entitled to additional compensation for such risk; and all such interest shall be payable by Borrower upon demand by Agent.

4.4 LIBOR-Rate Unascertainable; Illegality; Increased Costs; Deposits Not Available.

4.4.1 Unascertainable.

If on any date on which a LIBOR-Rate would otherwise be determined, the Agent shall have determined that:

(i)    adequate and reasonable means do not exist for ascertaining such LIBOR-Rate, or

(ii)    a contingency has occurred which materially and adversely affects the London interbank eurodollar market relating to the LIBOR-Rate, then the Agent shall have the rights specified in Section 4.4.3 [Agent's and Bank's Rights].

51

Table of Contents

4.4.2 Illegality; Increased Costs; Deposits Not Available.

If at any time any Bank shall have determined that:

(i)    the making, maintenance or funding of any Loan to which a LIBOR-Rate Option applies has been made impracticable or unlawful by compliance by such Bank in good faith with any Law or any interpretation or application thereof by any Official Body or with any request or directive of any such Official Body (whether or not having the force of Law), or

(ii)    such LIBOR-Rate Option will not adequately and fairly reflect the cost to such Bank of the establishment or maintenance of any such Loan, or

(iii)    after making all reasonable efforts, deposits of the relevant amount in Dollars for the relevant Interest Period for a Loan, or to banks generally, to which a LIBOR-Rate Option applies, respectively, are not available to such Bank with respect to such Loan, or to banks generally, in the interbank eurodollar market,

then the Agent shall have the rights specified in Section 4.4.3 [Agent's and Bank's Rights].

4.4.3 Agent's and Bank's Rights.

In the case of any event specified in Section 4.4.1 [Unascertainable] above, the Agent shall promptly so notify the Banks and the Borrower thereof, and in the case of an event specified in Section 4.4.2 [Illegality; Increased Costs; Deposits Not Available] above, such Bank shall promptly so notify the Agent and endorse a certificate to such notice as to the specific circumstances of such notice, and the Agent shall promptly send copies of such notice and certificate to the other Banks and the Borrower. Upon such date as shall be specified in such notice (which shall not be earlier than the date such notice is given), the obligation of (A) the Banks, in the case of such notice given by the Agent, or (B) such Bank, in the case of such notice given by such Bank, to allow the Borrower to select, convert to or renew a LIBOR-Rate Option shall be suspended until the Agent shall have later notified the Borrower, or such Bank shall have later notified the Agent, of the Agent's or such Bank's, as the case may be, determination that the circumstances giving rise to such previous determination no longer exist. If at any time the Agent makes a determination under Section 4.4.1 [Unascertainable] and the Borrower has previously notified the Agent of its selection of, conversion to or renewal of a LIBOR-Rate Option and such Interest Rate Option has not yet gone into effect, such notification shall be deemed to provide for selection of, conversion to or renewal of the Base Rate Option otherwise available with respect to such Loans. If any Bank notifies the Agent of a determination under Section 4.4.2 [Illegality; Increased Costs; Deposits Not Available], the Borrower shall, subject to the Borrower's indemnification Obligations under Section 2.9.8 [Indemnity], as to any Loan of the Bank to which a LIBOR-Rate Option applies, on the date specified in such notice either convert such Loan to the Base Rate Option otherwise available with respect to such Loan or prepay such Loan in accordance with Section 5.6 [Voluntary Prepayments]. Absent due notice from the Borrower of conversion or prepayment, such Loan shall automatically be converted to the Base Rate Option otherwise available with respect to such Loan upon such specified date.

52

Table of Contents

4.5 Selection of Interest Rate Options.

If the Borrower fails to select a new Interest Period to apply to any Borrowing Tranche of Loans under the LIBOR-Rate Option at the expiration of an existing Interest Period applicable to such Borrowing Tranche in accordance with the provisions of Section 4.2 [Interest Periods], the Borrower shall be deemed to have converted such Borrowing Tranche to the Base Rate Option, commencing upon the last day of the existing Interest Period.

5. PAYMENTS

5.1 Payments.

All payments and prepayments to be made in respect of principal, interest, Commitment Fees, Letter of Credit Fees, Agent's Fee or other fees or amounts due from the Borrower hereunder shall be payable prior to 11:00 a.m., Pittsburgh time, on the date when due without presentment, demand, protest or notice of any kind, all of which are hereby expressly waived by the Borrower, and without set-off, counterclaim or other deduction of any nature, and an action therefor shall immediately accrue. Such payments shall be made to the Agent at the Principal Office for the account of PNC Bank with respect to Swing Loans and for the ratable accounts of the Banks with respect to the Revolving Credit Loans in U.S. Dollars and in immediately available funds, and the Agent shall promptly distribute such amounts to the Banks in immediately available funds, provided that in the event payments are received by 11:00 a.m., Pittsburgh time, by the Agent with respect to the Loans and such payments are not distributed to the Banks on the same day received by the Agent, the Agent shall pay the Banks the Federal Funds Effective Rate with respect to the amount of such payments for each day held by the Agent and not distributed to the Banks. The Agent's and each Bank's statement of account, ledger or other relevant record shall, in the absence of manifest error, be conclusive as the statement of the amount of principal of and interest on the Loans and other amounts owing under this Agreement and shall be deemed an "account stated."

5.2    Pro Rata Treatment of Banks. Each borrowing of Revolving Credit Loans shall be allocated to each Bank according to its Ratable Share, and each selection of, conversion to or renewal of any Interest Rate Option and each payment or prepayment by the Borrower with respect to principal, interest, Commitment Fee and Letter of Credit Fees (but excluding the Agent's Fee and the Issuing Bank's fronting fee) shall (except as otherwise may be provided with respect to a Defaulting Bank and except as provided in Section 4.4.3 [Agent's and Bank's Rights] in the case of an event specified in Section 4.4 [LIBOR Rate Unascertainable; Etc.], 5.6.2 [Replacement of a Bank] or 5.8 [Increased Costs]) be payable ratably among the Banks entitled to such payment in accordance with the amount of principal, interest, Commitment Fees, and Letter of Credit Fees, as set forth in this Agreement. Notwithstanding any of the foregoing, each borrowing or payment or prepayment by the Borrower of principal, interest, fees or other amounts from the Borrower with respect to Swing Loans shall be made by or to PNC according to Section 2.6.5 [Borrowings to Repay Swing Loans].

5.3    Sharing of Payments by Banks. If any Bank shall, by exercising any right of setoff, counterclaim or banker's lien, by receipt of voluntary payment, by realization upon security, or by any other non-pro rata source, obtain payment in respect of any principal of or

53

Table of Contents

interest on any of its Loans or other obligations hereunder resulting in such Bank's receiving payment of a proportion of the aggregate amount of its Loans and accrued interest thereon or other such obligations greater than the pro-rata share of the amount such Bank is entitled thereto, then the Bank receiving such greater proportion shall (a) notify the Agent of such fact, and (b) purchase (for cash at face value) participations in the Loans and such other obligations of the other Banks, or make such other adjustments as shall be equitable, so that the benefit of all such payments shall be shared by the Banks ratably in accordance with the aggregate amount of principal of and accrued interest on their respective Loans and other amounts owing them, provided that:

(i)    if any such participations are purchased and all or any portion of the payment giving rise thereto is recovered, such participations shall be rescinded and the purchase price restored to the extent of such recovery, together with interest or other amounts, if any, required by Law (including court order) to be paid by the Bank or the holder making such purchase; and

(ii)    the provisions of this Section 5.3 shall not be construed to apply to (x) any payment made by the Loan Parties pursuant to and in accordance with the express terms of the Loan Documents or (y) any payment obtained by a Bank as consideration for the assignment of or sale of a participation in any of its Loans or Participation Advances to any assignee or participant, other than to the Borrower or any Subsidiary thereof (as to which the provisions of this Section 5.3 shall apply).

Each Loan Party consents to the foregoing and agrees, to the extent it may effectively do so under applicable Law, that any Bank acquiring a participation pursuant to the foregoing arrangements may exercise against each Loan Party rights of setoff and counterclaim with respect to such participation as fully as if such Bank were a direct creditor of each Loan Party in the amount of such participation.

5.4    Presumptions by Agent. Unless the Agent shall have received notice from the Borrower prior to the date on which any payment is due to the Agent for the account of the Banks or the Issuing Bank hereunder that the Borrower will not make such payment, the Agent may assume that the Borrower has made such payment on such date in accordance herewith and may, in reliance upon such assumption, distribute to the Banks or the Issuing Bank, as the case may be, the amount due. In such event, if the Borrower has not in fact made such payment, then each of the Banks or the Issuing Bank, as the case may be, severally agrees to repay to the Agent forthwith on demand the amount so distributed to such Bank or the Issuing Bank, with interest thereon, for each day from and including the date such amount is distributed to it to but excluding the date of payment to the Agent, at the greater of the Federal Funds Effective Rate and a rate determined by the Agent in accordance with banking industry rules on interbank compensation.

5.5    Interest Payment Dates. Interest on Loans to which the Base Rate Option applies shall be due and payable in arrears on each Payment Date. Interest on Loans to which the LIBOR Rate Option applies shall be due and payable on the last day of each Interest Period for those Loans and, if such Interest Period is longer than three (3) Months, also on the 90th day of such Interest Period. Interest on mandatory prepayments of principal under Section 5.7

54

Table of Contents

[Mandatory Prepayments] shall be due on the date such mandatory prepayment is due. Interest on the principal amount of each Loan or other monetary Obligation shall be due and payable on demand after such principal amount or other monetary Obligation becomes due and payable (whether on the stated Expiration Date, upon acceleration or otherwise).

5.6 Voluntary Prepayments.

5.6.1 Right to Prepay.

The Borrower shall have the right at its option from time to time to prepay the Loans in whole or part without premium or penalty (except as provided in Section 5.6.2 [Replacement of a Bank] below, in Section 5.8 [Increased Costs] and Section 5.10 [Indemnity]).

(i)    at any time with respect to any Loan to which the Base Rate Option applies,

(ii)    on the last day of the applicable Interest Period with respect to Loans to which a LIBOR-Rate Option applies,

(iii)    on the date specified in a notice by any Bank pursuant to Section 4.4 [LIBOR-Rate Unascertainable, Etc.] with respect to any Loan to which a LIBOR-Rate Option applies.

Whenever the Borrower desires to prepay any part of the Loans, it shall provide a prepayment notice to the Agent by 1:00 p.m. on the date of prepayment of the Revolving Credit Loans and no later than 2:00 p.m., Pittsburgh time, on the date of prepayment of Swing Loans, setting forth the following information:

(x)    the date, which shall be a Business Day, on which the proposed prepayment is to be made;

(y)    a statement indicating the application of prepayment between Swing Loans and Revolving Loans; and

(z)    the total principal amount of such prepayment, which shall not be less than $100,000 for any Swing Loan or $500,000 for any Revolving Credit Loan; provided however, such prepayment may be less than such amounts if such prepayment pays in full all outstanding amounts under the Swing Loans or Revolving Credit Loans, as applicable.

All prepayment notices shall be irrevocable. The principal amount of the Loans for which a prepayment notice is given, together with interest on such principal amount except with respect to Loans to which the Base Rate Option applies, shall be due and payable on the date specified in such prepayment notice as the date on which the proposed prepayment is to be made. Except as provided in Section 4.4.3 [Agent's and Bank's rights], if the Borrower prepays a Loan but fails to specify the applicable Borrowing Tranche which the Borrower is prepaying, the prepayment shall be applied first to Loans to which the Base Rate Option applies, then to Loans to which the LIBOR-Rate Option applies. Any prepayment hereunder shall be subject to the Borrower's Obligation to indemnify the Banks under Section 5.10 [Indemnity].

Table of Contents

5.6.2 Replacement of a Bank.

In the event any Bank (i) gives notice under Section 4.4 [LIBOR Rate Unascertainable, Etc.], (ii) requests compensation under Section 5.8 [Increased Costs], or requires the Borrower to pay any Indemnified Taxes or additional amount to any Bank or any Official Body for the account of any Bank pursuant to Section 5.9 [Taxes], (iii) is a Defaulting Bank, (iv) becomes subject to the control of an Official Body (other than normal and customary supervision), or (v) is a Non-Consenting Bank referred to in Section 11.1 [Modifications, Amendments or Waivers], (iv) becomes subject to the control of an Official Body (other than normal and customary supervision), or (v) is a Non-Consenting Bank referred to in Section 11.1 [Modifications, Amendments or Waivers], then in any such event the Borrower may, at its sole expense, upon notice to such Bank and the Agent, require such Bank to assign and delegate, without recourse (in accordance with and subject to the restrictions contained in, and consents required by, Section 11.9 [Successors and Assigns]), all of its interests, rights (other than existing rights to payments pursuant to Sections 5.8 [Increased Costs] or 5.9 [Taxes]) and obligations under this Agreement and the related Loan Documents to an assignee that shall assume such obligations (which assignee may be another Bank, if a Bank accepts such assignment), provided that:

(i)    the Borrower shall have paid to the Agent the assignment fee specified in Section 11.9 [Successors and Assigns];

(ii)    such Bank shall have received payment of an amount equal to the outstanding principal of its Loans and Participation Advances, accrued interest thereon, accrued fees and all other amounts payable to it hereunder and under the other Loan Documents (including any amounts under Section 2.9.8 [Indemnity]) from the assignee (to the extent of such outstanding principal and accrued interest and fees) or the Borrower (in the case of all other amounts);

(iii)    in the case of any such assignment resulting from a claim for compensation under Section 5.8.1 [Increased Costs Generally] or payments required to be made pursuant to Section 5.9 [Taxes], such assignment will result in a reduction in such compensation or payments thereafter; and

(iv)    such assignment does not conflict with applicable Law.

A Bank shall not be required to make any such assignment or delegation if, prior thereto, as a result of a waiver by such Bank or otherwise, the circumstances entitling the Borrower to require such assignment and delegation cease to apply.

5.7 Mandatory Prepayments.

5.7.1 Prepayment Event.

(i)    Promptly (and in any event within three Business Days) after any officer of the Borrower obtains knowledge of any Prepayment Event or any action of the Borrower or any other Person that would be reasonably likely to result in a Prepayment Event, notice thereof in the form of an Officer's Certificate describing in reasonable detail the facts and

(ii)    Change in Control. At any time following the occurrence of a Prepayment Event (subject to the penultimate sentence of this Section 5.7.1(ii), the Agent shall have the right at its option, exercisable by the giving of notice to the Borrower (a "Prepayment Election Notice"), to elect to require the prepayment by the Borrower of all Loans on the prepayment date specified by Agent in such Prepayment Election Notice (which shall not in any event be less than 30 days nor more than 60 days after the date on which such holder shall have given such Prepayment Election Notice to the Borrower). On the prepayment date specified in any Prepayment Election Notice given by Agent, the Borrower will prepay all Loans. The right of the Agent to give a Prepayment Election Notice for the prepayment of the Loans pursuant to this Section following a Prepayment Event shall expire at the close of business in New York City on the one hundred-twentieth day following the later of (x) the date of such Prepayment Event and (y) actual receipt by Agent of notice of such Prepayment Event pursuant to Section 5.7.1(ii). Notwithstanding any provision hereof to the contrary, no failure on the part of the Agent to exercise its right to require the prepayment thereof by the Borrower pursuant to this Section 5.7.1(ii) following a Prepayment Event shall be deemed a waiver of or otherwise impair the rights of Agent pursuant to this Section 5.7.1(ii) in respect of any other events or circumstances constituting a Prepayment Event.

(a)"Prepayment Event" shall mean (i) any Loan Party's Change in Control, or (ii) any Control Event with respect to the Borrower or any of the other Loan Parties or (iii) any Parent Change in Control with respect to the Parent.

(c)"Control Event" means:

(i)the execution by the Parent or any of its Subsidiaries or Affiliates, or the Borrower or any of its Subsidiaries or Affiliates, of any agreement with respect to any proposed transaction or event or series of transactions or events which, individually or in the aggregate, would reasonably be expected to result in a Parent Change in Control or an Borrowers' Change in Control, or

(ii)the execution of any written agreement which, when fully performed by the parties thereto, would result in a Parent Change in Control or a Loan Party's Change in Control.

(i)    impose, modify or deem applicable any reserve, special deposit, compulsory loan, insurance charge or similar requirement against assets of, deposits with or for the account of, or credit extended or participated in by, any Bank (except any reserve requirement reflected in the LIBOR Rate) or the Issuing Bank;

(ii)    subject any Recipient to any Taxes (other than (A) Indemnified Taxes, (B) Taxes described in clauses (ii) through (iv) of the definition of Excluded Taxes and (C) Connection Income Taxes) on its loans, loan principal, letters of credit, commitments, or other obligations, or its deposits, reserves, other liabilities or capital attributable thereto; or

(iii)    impose on any Bank, the Issuing Bank or the London interbank market any other condition, cost or expense (other than Taxes) affecting this Agreement or Loans made by such Bank or any Letter of Credit or participation therein;

and the result of any of the foregoing shall be to increase the cost to such Bank or such other Recipient of making, converting to, continuing or maintaining any Loan or of maintaining its obligation to make any such Loan, or to increase the cost to such Bank, the Issuing Bank or such other Recipient of participating in, issuing or maintaining any Letter of Credit (or of maintaining its obligation to participate in or to issue any Letter of Credit), or to reduce the amount of any sum received or receivable by such Bank, the Issuing Bank or other Recipient hereunder (whether of principal, interest or any other amount) then, upon request of such Bank (accompanied by the certificate described in Section 5.8.3 [Certificates for Reimbursement, etc.]), the Issuing Bank or other Recipient, the Borrower will pay to such Bank, the Issuing Bank or other Recipient, as the case may be, within the timeframe set forth in Section 5.8.3 [Certificates for Reimbursement, etc.], such additional amount or amounts as will compensate such Bank or the Issuing Bank, as the case may be, for such additional costs incurred or reduction suffered.

5.8.2    Capital Requirements. If any Bank or the Issuing Bank reasonably determines that any Change in Law affecting such Bank or the Issuing Bank or any lending office of such Bank or such Bank's or the Issuing Bank's holding company, if any, regarding capital or liquidity requirements has or would have the effect of reducing the rate of return on such Bank's or the Issuing Bank's capital or on the capital of such Bank's or the Issuing Bank's holding company, if any, as a consequence of such Bank's or Issuing Bank's obligations under this Agreement, the Commitments of such Bank or the Loans made by, or participations in Letters of

58

Table of Contents

Credit or Swing Loans held by, such Bank, or the Letters of Credit issued by the Issuing Bank, to a level below that which such Bank or the Issuing Bank or such Bank's or the Issuing Bank's holding company would have achieved but for such Change in Law (taking into consideration such Bank's or the Issuing Bank's policies and the policies of such Bank's or the Issuing Bank's holding company with respect to capital adequacy), then from time to time upon written request of such Bank or the Issuing Bank (accompanied by the certificate described in Section 5.8.3 [Certificates for Reimbursement, etc.], the Borrower will pay to such Bank or the Issuing Bank, as the case may be, within the timeframe set forth in Section 5.8.3 [Certificates for Reimbursement, etc.], such additional amount or amounts as will compensate such Bank or the Issuing Bank or such Bank's or the Issuing Bank's holding company for any such reduction suffered.

5.8.3    Certificates for Reimbursement; Repayment of Outstanding Loans; Borrowing of New Loans. A certificate of a Bank or the Issuing Bank setting forth the amount or amounts necessary to compensate such Bank or the Issuing Bank or its holding company, as the case may be, as specified in Sections 5.8.1 [Increased Costs Generally] or 5.8.2 [Capital Requirements] and setting forth the calculations of such amount or amounts and delivered to the Borrower shall be conclusive absent manifest error. The Borrower shall pay such Bank or the Issuing Bank, as the case may be, the amount shown as due on any such certificate within ten (10) days after receipt thereof.

5.8.4.    Delay in Requests. Failure or delay on the part of any Bank or the Issuing Bank to demand compensation pursuant to this Section shall not constitute a waiver of such Bank's or the Issuing Bank's right to demand such compensation, provided that the Borrower shall not be required to compensate a Bank or the Issuing Bank pursuant to this Section for any increased costs incurred or reductions suffered more than six months prior to the date that such Bank or the Issuing Bank, as the case may be, notifies the Borrower of the Change in Law giving rise to such increased costs or reductions and of such Bank's or the Issuing Bank's intention to claim compensation therefor (except that, if the Change in Law giving rise to such increased costs or reductions is retroactive, then the six (6) month period referred to above shall be extended to include the period of retroactive effect thereof).

5.9 Taxes.

5.9.1    Issuing Bank. For purposes of this Section 5.9, the term "Bank" includes the Issuing Bank.

5.9.2    Payments Free of Taxes. Any and all payments by or on account of any obligation of any Loan Party under any Loan Document shall be without deduction or withholding for any Taxes, except as required by applicable Law. If any applicable Law (as determined in the good faith discretion of an applicable Withholding Agent) requires the deduction or withholding of any Tax from any such payment by a Withholding Agent, then the applicable Withholding Agent shall be entitled to make such deduction or withholding and shall timely pay the full amount deducted or withheld to the relevant Official Body in accordance with applicable Law and, if such Tax is an Indemnified Tax, then the sum payable by the applicable Loan Party shall be increased as necessary so that after such deduction or withholding has been made (including such deductions and withholdings applicable to additional sums payable under

59

Table of Contents

this Section 5.9 [Taxes]) the applicable Recipient receives an amount equal to the sum it would have received had no such deduction or withholding been made.

5.9.3    Payment of Other Taxes by the Borrower. The Borrower shall timely pay to the relevant Official Body in accordance with applicable Law, or at the option of the Agent timely reimburse it for the payment of, any Other Taxes.

5.9.4    Indemnification by the Borrower. The Borrower shall indemnify each Recipient, within ten (10) days after demand therefor, for the full amount of any Indemnified Taxes (including Indemnified Taxes imposed or asserted on or attributable to amounts payable under this Section 5.9 [Taxes]) payable or paid by such Recipient or required to be withheld or deducted from a payment to such Recipient and any reasonable expenses arising therefrom or with respect thereto, whether or not such Indemnified Taxes were correctly or legally imposed or asserted by the relevant Official Body. A certificate as to the amount of such payment or liability delivered to the Borrower by a Bank (with a copy to the Agent), or by the Agent on its own behalf or on behalf of a Bank, shall be conclusive absent manifest error.

5.9.5    Indemnification by the Banks. Each Bank shall severally indemnify the Agent, within ten (10) days after demand therefor, for (i) any Indemnified Taxes attributable to such Bank (but only to the extent that any Loan Party has not already indemnified the Agent for such Indemnified Taxes and without limiting the obligation of any of the Loan Parties to do so), (ii) any Taxes attributable to such Bank's failure to comply with the provisions of Section 11.9.4 [Participations] relating to the maintenance of a Participant Register, and (iii) any Excluded Taxes attributable to such Bank, in each case, that are payable or paid by the Agent in connection with any Loan Document, and any reasonable expenses arising therefrom or with respect thereto, whether or not such Taxes were correctly or legally imposed or asserted by the relevant Official Body. A certificate as to the amount of such payment or liability delivered to any Bank by the Agent shall be conclusive absent manifest error. Each Bank hereby authorizes the Agent to set off and apply any and all amounts at any time owing to such Bank under any Loan Document or otherwise payable by the Agent to the Bank from any other source against any amount due to the Agent under this Section 5.9.5 [Indemnification by the Banks].

5.9.6    Evidence of Payments. As soon as practicable after any payment of Taxes by any Loan Party to an Official Body pursuant to this Section 5.9 [Taxes], such Loan Party shall deliver to the Agent the original or a certified copy of a receipt issued by such Official Body evidencing such payment, a copy of the return reporting such payment or other evidence of such payment reasonably satisfactory to the Agent.

5.9.7    Status of Banks.

(i)    Any Bank that is entitled to an exemption from or reduction of withholding Tax with respect to payments made under any Loan Document shall deliver to the Borrower and the Agent, at the time or times reasonably requested by the Borrower or the Agent, such properly completed and executed documentation reasonably requested by the Borrower or the Agent as will permit such payments to be made without withholding or at a reduced rate of withholding. In addition, any Bank, if reasonably requested by the Borrower or the Agent, shall deliver such other documentation prescribed by applicable Law or reasonably requested by the

60

Table of Contents

Borrower or the Agent as will enable the Borrower or the Agent to determine whether or not such Bank is subject to backup withholding or information reporting requirements. Notwithstanding anything to the contrary in the preceding two sentences, the completion, execution and submission of such documentation (other than such documentation set forth in Section 5.9.7(ii)(a), (ii)(b) and (ii)(d) below) shall not be required if in the Bank's reasonable judgment such completion, execution or submission would subject such Bank to any material unreimbursed cost or expense or would materially prejudice the legal or commercial position of such Bank.

(ii)    Without limiting the generality of the foregoing, in the event that the Borrower is a U.S. Borrower,

(a)    any Bank that is a U.S. Person shall deliver to the Borrower and the Agent on or prior to the date on which such Bank becomes a Bank under this Agreement (and from time to time thereafter upon the reasonable request of the Borrower or the Agent), executed originals of IRS Form W-9 certifying that such Bank is exempt from U.S. federal backup withholding tax;

(b)    any Foreign Bank shall, to the extent it is legally entitled to do so, deliver to the Borrower and the Agent (in such number of copies as shall be requested by the recipient) on or prior to the date on which such Foreign Bank becomes a Bank under this Agreement (and from time to time thereafter upon the reasonable request of the Borrower or the Agent), whichever of the following is applicable:

(i) in the case of a Foreign Bank claiming the benefits of an income tax treaty to which the United States is a party (x) with respect to payments of interest under any Loan Document, executed originals of IRS Form W-8BEN establishing an exemption from, or reduction of, U.S. federal withholding Tax pursuant to the "interest" article of such tax treaty and (y) with respect to any other applicable payments under any Loan Document, IRS Form W-8BEN establishing an exemption from, or reduction of, U.S. federal withholding Tax pursuant to the "business profits" or "other income" article of such tax treaty;

(iv) to the extent a Foreign Bank is not the beneficial owner, executed originals of IRS Form W-8IMY, accompanied by IRS Form W-8ECI, IRS Form W-8BEN, a U.S. Tax Compliance Certificate substantially in the form of Exhibit 5.9.7(B) or Exhibit 5.9.7(C), IRS Form W-9, and/or other certification documents from each beneficial owner, as applicable; provided that if the Foreign Bank is a partnership and one or more direct or indirect partners of such Foreign Bank are claiming the portfolio interest exemption, such Foreign Bank may provide a U.S. Tax Compliance Certificate substantially in the form of Exhibit 5.9.7(D) on behalf of each such direct and indirect partner;

(c)    any Foreign Bank shall, to the extent it is legally entitled to do so, deliver to the Borrower and the Agent (in such number of copies as shall be requested by the recipient) on or prior to the date on which such Foreign Bank becomes a Bank under this Agreement (and from time to time thereafter upon the reasonable request of the Borrower or the Agent), executed originals of any other form prescribed by applicable Law as a basis for claiming exemption from or a reduction in U.S. federal withholding Tax, duly completed, together with such supplementary documentation as may be prescribed by applicable Law to permit the Borrower or the Agent to determine the withholding or deduction required to be made; and

(d)    if a payment made to a Bank under any Loan Document would be subject to U.S. federal withholding Tax imposed by FATCA if such Bank were to fail to comply with the applicable reporting requirements of FATCA (including those contained in Section 1471(b) or 1472(b) of the Code, as applicable), such Bank shall deliver to the Borrower and the Agent at the time or times prescribed by law and at such time or times reasonably requested by the Borrower or the Agent such documentation prescribed by applicable law (including as prescribed by Section 1471(b)(3)(C)(i) of the Code) and such additional documentation reasonably requested by the Borrower or the Agent as may be necessary for the Borrower and the Agent to comply with their obligations under FATCA and to determine that such Bank has complied with such Bank's obligations under FATCA or to determine the amount to deduct and withhold from such payment. Solely for purposes of this clause (D), "FATCA" shall include any amendments made to FATCA after the date of this Agreement.

Each Bank agrees that if any form or certification it previously delivered expires or becomes obsolete or inaccurate in any respect, it shall update such form or certification or promptly notify the Borrower and the Agent in writing of its legal inability to do so.

5.9.8    Treatment of Certain Refunds. If any party determines, in its sole discretion exercised in good faith, that it has received a refund of any Taxes as to which it has been indemnified pursuant to this Section 5.9 [Taxes] (including by the payment of additional amounts pursuant to this Section 5.9 [Taxes]), it shall pay to the indemnifying party an amount equal to such refund (but only to the extent of indemnity payments made under this Section 5.9 [Taxes] with respect to the Taxes giving rise to such refund), net of all out-of-pocket expenses (including Taxes) of such indemnified party and without interest (other than any interest paid by the relevant Official Body with respect to such refund). Such party will make such payment to

62

Table of Contents

the indemnified party within ten (10) days after the party has determined that it owes amounts to the indemnifying party pursuant to the first sentence of this Section 5.9.8 [Treatment of Certain Refunds]. Such indemnifying party, upon the request of such indemnified party shall repay to such indemnified party the amount paid over pursuant to this Section 5.9.8 [Treatment of Certain Refunds] (plus any penalties, interest or other charges imposed by the relevant Official Body) in the event that such indemnified party is required to repay such refund to such Official Body. Notwithstanding anything to the contrary in this Section 5.9.8 [Treatment of Certain Refunds]), in no event will the indemnified party be required to pay any amount to an indemnifying party pursuant to this Section 5.9.8 [Treatment of Certain Refunds] the payment of which would place the indemnified party in a less favorable net after-Tax position than the indemnified party would have been in if the indemnification payments or additional amounts giving rise to such refund had never been paid. This paragraph shall not be construed to require any indemnified party to make available its Tax returns (or any other information relating to its Taxes that it deems confidential) to the indemnifying party or any other Person.

5.9.9    Survival. Each party's obligations under this Section 5.9 [Taxes] shall survive the resignation of the Agent or any assignment of rights by, or the replacement of, a Bank, the termination of the Commitments and the repayment, satisfaction or discharge of all Obligations.

5.10    Indemnity. In addition to the compensation or payments required by Section 5.8 [Increased Costs]or Section 5.9 [Taxes], the Borrower shall indemnify each Bank against all liabilities, losses or expenses (including loss of anticipated profits, any foreign exchange losses and any loss or expense arising from the liquidation or reemployment of funds obtained by it to maintain such Loan, from fees payable to terminate the deposits from which such funds were obtained or from the performance of any foreign exchange contract) which such Bank sustains or incurs as a consequence of any:

(i)    payment, prepayment, conversion or renewal of any Loan to which a LIBOR Rate Option applies on a day other than the last day of the corresponding Interest Period (whether or not such payment or prepayment is mandatory, voluntary or automatic and whether or not such payment or prepayment is then due),

(ii)    attempt by the Borrower to revoke (expressly, by later inconsistent notices or otherwise) in whole or part any Loan Requests under Section 2.5 [Revolving Credit Loan Requests; Swing Loan Requests] or Section 4.2 [Interest Periods] or notice relating to prepayments under Section 5.6 [Voluntary Prepayments], or

(iii)    default by the Borrower in the performance or observance of any covenant or condition contained in this Agreement or any other Loan Document, including any failure of the Borrower to pay when due (by acceleration or otherwise) any principal, interest, Commitment Fee or any other amount due hereunder.

If any Bank sustains or incurs any such loss or expense, it shall from time to time notify the Borrower of the amount determined in good faith by such Bank (which determination may include such assumptions, allocations of costs and expenses and averaging or attribution methods as such Bank shall deem reasonable), which notice shall include the calculations of any such amount, to be necessary to indemnify such Bank for such loss or expense. Such notice shall

63

Table of Contents

set forth in reasonable detail the basis for such determination. Such amount shall be due and payable by the Borrower to such Bank ten (10) Business Days after such notice is given.

5.11    Settlement Date Procedures. In order to minimize the transfer of funds between the Banks and the Agent, the Borrower may borrow, repay and reborrow Swing Loans and [PNC] may make Swing Loans as provided in Section 2.1.2 [Swing Loan Commitments] hereof during the period between Settlement Dates. The Agent shall notify each Bank of its Ratable Share of the total of the Revolving Credit Loans and the Swing Loans (each a "Required Share"). On such Settlement Date, each Bank shall pay to the Agent the amount equal to the difference between its Required Share and its Revolving Credit Loans, and the Agent shall pay to each Bank its Ratable Share of all payments made by the Borrower to the Agent with respect to the Revolving Credit Loans. The Agent shall also effect settlement in accordance with the foregoing sentence on the proposed Borrowing Dates for Revolving Credit Loans and on [Mandatory Prepayment Dates] and may at its option effect settlement on any other Business Day. These settlement procedures are established solely as a matter of administrative convenience, and nothing contained in this Section 5.11 shall relieve the Banks of their obligations to fund Revolving Credit Loans on dates other than a Settlement Date pursuant to Section 2.1.2 [Swing Loan Commitment]. The Agent may at any time at its option for any reason whatsoever require each Bank to pay immediately to the Agent such Bank's Ratable Share of the outstanding Revolving Credit Loans and each Bank may at any time require the Agent to pay immediately to such Bank its Ratable Share of all payments made by the Borrower to the Agent with respect to the Revolving Credit Loans.

6.1.6 No Conflict.

Neither the execution and delivery of this Agreement or the other Loan Documents by any Loan Party nor the consummation of the transactions herein or therein contemplated nor compliance with the terms and provisions hereof or thereof by any Loan Party will conflict with, constitute a default under or result in any breach of (i) the terms and conditions of the Organizational Documents of any Loan Party or (ii) any Law or any material Coal Supply Contract, Coal Lease or other agreement or instrument or any order, writ, judgment, injunction or decree to which any Loan Party or any of its Subsidiaries is a party or by which it or any of its Subsidiaries is bound or to which it is subject, or result in the creation or enforcement of any Lien, charge or encumbrance whatsoever upon any property (now or hereafter acquired) of any Loan Party or any of its Subsidiaries (other than Liens granted under the Loan Documents and Liens granted under the Note Purchase Documents).

None of the Loan Parties or any Subsidiaries of any Loan Party is in violation of any order, writ, injunction or decree of any Official Body (including without limitation Environmental Laws or the USA Patriot Act) which either individually or in the aggregate could reasonably be expected to result in a Material Adverse Change.

6.1.8 Title to Properties.

Schedule 6.1.8 identifies all of the real property interests, both owned and leased, of the Loan Parties and sets forth, with respect to each such real property interest the name of the Loan Party which is the owner or lessee thereof, as the case may be, and, if leased, the name of the owner and lessor thereof. Each Loan Party and each Subsidiary of each Loan Party has good and marketable title to all real estate owned by it and a valid leasehold interest in all properties, assets and other rights which it purports to lease or which are reflected as owned or leased on its books and records, free and clear of all Liens and encumbrances except Permitted Liens, and subject to the terms and conditions of the applicable leases; provided, however, a Loan Party shall not be in breach of the foregoing in the event that (i) it fails to own a valid leasehold interest which, either considered alone or together with all other such valid leaseholds which it fails to own, is not material to the continued operations of such Loan Party as contemplated by the Financial Projections or its mining plan as in effect on the Closing Date or (ii) the Loan Party's interest in a leasehold is less than fully marketable because the consent of the lessor to future assignments has not been obtained. All leases of property which are material to the continued operations of each Loan Party as contemplated by the Financial Projections and its

66

Table of Contents

mining plan as in effect on the Closing Date are in full force and effect without the necessity for any consent which has not previously been obtained.

The Financial Projections represent a reasonable range of possible results in light of the history of the business, present and foreseeable conditions and the intentions of the Borrower's management. The Financial Projections represent the Borrower's good faith estimate of future performance based upon historical financial information and upon assumptions which were reasonable at the time of the preparation thereof and which remain reasonable as of the date hereof.

(iii)    Accuracy of Financial Statements; Material Liabilities. Except for liabilities arising in the ordinary course of business and the Indebtedness arising in connection with the Notes and the Note Purchase Documents since the date of the last Historical Statement, neither the Borrower nor any Subsidiary of the Borrower has incurred any liabilities, contingent or otherwise, or forward or long-term commitments that are not disclosed in the Historical Statements or in the notes thereto or on Schedule 6.1.9, and except as disclosed therein there are no unrealized or anticipated losses from any commitments of the Borrower or any Subsidiary of the Borrower which either individually or in the aggregate could reasonably be expected to result in a Material Adverse Change. Since December 31, 2011, no Material Adverse Change has occurred.

Neither this Agreement nor any other Loan Document, nor any certificate, statement, agreement or other documents furnished by any Loan Party to the Agent or any Bank in connection herewith or therewith, contains any untrue statement of a material fact or omits to state a material fact necessary in order to make the statements contained herein and therein, in light of the circumstances under which they were made, not misleading. There is no fact known to any Loan Party which materially adversely affects the business, property, assets, financial condition, results of operations or prospects of any Loan Party or Subsidiary of any Loan Party which has not been set forth in this Agreement or in the certificates, statements, agreements or other documents furnished in writing to the Agent and the Banks prior to or at the date hereof in connection with the transactions contemplated hereby.

If an Event of Default shall have occurred and be continuing, each Bank, the Issuing Bank, and each of their respective Affiliates and any participant of such Bank or Affiliate which has agreed in writing to be bound by the provisions of Section 5.3 [Sharing of Payments by Banks] is hereby authorized at any time and from time to time, to the fullest extent permitted by applicable Law, to set off and apply any and all deposits (general or special, time or demand, provisional or final, in whatever currency) at any time held and other obligations (in whatever currency) at any time owing by such Bank, the Issuing Bank or any such Affiliate or participant to or for the credit or the account of any Loan Party (other than TWCC) against any and all of the Obligations of such Loan Party now or hereafter existing under this Agreement or any other Loan Document to such Bank, the Issuing Bank, Affiliate or participant, irrespective of whether or not such Bank, Issuing Bank, Affiliate or participant shall have made any demand under this Agreement or any other Loan Document, whether or not such debt owing to or funds held for the account of the Borrower or such other Loan Party (other than TWCC) is or are matured or unmatured and regardless of the existence or adequacy of any Collateral, Guaranty or any other security, right or remedy available to any Bank, Issuing Bank, or the Agent. The rights of each Bank, the Issuing Bank and their respective Affiliates and participants under this Section are in addition to other rights and remedies (including other rights of setoff) that such Bank, the Issuing Bank or their respective Affiliates and participants may have. Each Bank and the Issuing Bank agrees to notify the Borrower and the Agent promptly after any such setoff and application; provided that the failure to give such notice shall not affect the validity of such setoff and application. Notwithstanding anything contained in this Section 9.2.3 to the contrary, to the extent that Borrower maintains a deposit account with any Bank, which Borrower has identified to the Agent as containing monies solely for the payment of black lung trust fund obligations (the "Black Lung Trust Account"), the Banks agree that they will not set-off against any monies contained in such Black Lung Trust Account; and

If an Event of Default shall occur and be continuing, and whether or not the Agent shall have accelerated the maturity of Loans pursuant to any of the foregoing provisions of this Section 9.2, the Agent or any Bank, if owed any amount with respect to the Loans, may proceed to protect and enforce its rights by suit in equity, action at law and/or other appropriate proceeding, whether for the specific performance of any covenant or agreement contained in this Agreement or the other Loan Documents, including as permitted by applicable Law the obtaining of the ex parte appointment of a receiver, and, if such amount shall have become due, by declaration or otherwise, proceed to enforce the payment thereof or any other legal or equitable right of the Agent or such Bank; and

9.2.5 Application of Proceeds.

From and after the date on which the Agent has taken any action pursuant to this Section 9.2 and until all Obligations of the Borrower and the Guarantors have been paid in full,

116

any and all proceeds received by the Agent from any sale or other disposition of the Collateral, or any part thereof, or the exercise of any other remedy by the Agent, shall be applied as follows:

(i)first, to reimburse the Agent and the Banks for out-of-pocket costs, expenses and disbursements, including reasonable attorneys' and paralegals' fees and legal expenses, incurred by the Agent or the Banks in connection with realizing on the Collateral or collection of any Obligations of any of the Loan Parties under any of the Loan Documents, including advances made by the Banks or any one of them or the Agent for the reasonable maintenance, preservation, protection or enforcement of, or realization upon, the Collateral, including advances for taxes, insurance, repairs and the like and reasonable expenses incurred to sell or otherwise realize on, or prepare for sale or other realization on, any of the Collateral;

Any notice required to be given by the Agent of a sale, lease, or other disposition of the Collateral or any other intended action by the Agent, if given ten (10) days prior to such proposed action, shall constitute commercially reasonable and fair notice thereof to the Borrower.

10. THE AGENT

10.1    Appointment and Authority. Each of the Banks and the Issuing Bank hereby irrevocably appoints PNC to act on its behalf as the Agent hereunder and under the other Loan Documents and authorizes the Agent to take such actions on its behalf and to exercise such powers as are delegated to the Agent by the terms hereof or thereof, together with such actions and powers as are reasonably incidental thereto. The provisions of this Section 10 are solely for the benefit of the Agent, the Banks and the Issuing Bank, and neither the Borrower nor any other Loan Party shall have rights as a third party beneficiary of any of such provisions, except that the Borrower shall have the rights granted to it in Section 10.6.

10.2    Rights as a Bank. The Person serving as the Agent hereunder shall have the same rights and powers in its capacity as a Bank as any other Bank and may exercise the same as

117

Table of Contents

though it were not the Agent and the term "Bank" or "Banks" shall, unless otherwise expressly indicated or unless the context otherwise requires, include the Person serving as the Agent hereunder in its individual capacity. Such Person and its Affiliates may accept deposits from, lend money to, act as the financial advisor or in any other advisory capacity for and generally engage in any kind of business with the Borrower or any Subsidiary or other Affiliate thereof as if such Person were not the Agent hereunder and without any duty to account therefor to the Banks.

10.3    Exculpatory Provisions. The Agent shall not have any duties or obligations except those expressly set forth herein and in the other Loan Documents. Without limiting the generality of the foregoing, the Agent:

(a)    shall not be subject to any fiduciary or other implied duties, regardless of whether a Potential Default or Event of Default has occurred and is continuing;

(b)    shall not have any duty to take any discretionary action or exercise any discretionary powers, except discretionary rights and powers expressly contemplated hereby or by the other Loan Documents that the Agent is required to exercise as directed in writing by the Required Banks (or such other number or percentage of the Banks as shall be expressly provided for herein or in the other Loan Documents); provided that the Agent shall not be required to take any action that, in its opinion or the opinion of its counsel, may expose the Agent to liability or that is contrary to any Loan Document or applicable Law; and

(c)    shall not, except as expressly set forth herein and in the other Loan Documents, have any duty to disclose, and shall not be liable for the failure to disclose, any information relating to the Borrower or any of its Affiliates that is communicated to or obtained by the Person serving as the Agent or any of its Affiliates in any capacity.

The Agent shall not be liable for any action taken or not taken by it (i) with the consent or at the request of the Required Banks (or such other number or percentage of the Banks as shall be necessary, or as the Agent shall believe in good faith shall be necessary, under the circumstances as provided in Sections 11.1 [Modifications, Amendments or Waivers] and 9.2 [Consequences of Event of Default]) or (ii) in the absence of its own gross negligence or willful misconduct. The Agent shall be deemed not to have knowledge of any Potential Default or Event of Default unless and until notice describing such Potential Default or Event of Default is given to the Agent by the Borrower, a Bank or the Issuing Bank.

The Agent shall not be responsible for or have any duty to ascertain or inquire into (i) any statement, warranty or representation made in or in connection with this Agreement or any other Loan Document, (ii) the contents of any certificate, report or other document delivered hereunder or thereunder or in connection herewith or therewith, (iii) the performance or observance of any of the covenants, agreements or other terms or conditions set forth herein or therein or the occurrence of any Potential Default or Event of Default, (iv) the validity, enforceability, effectiveness or genuineness of this Agreement, any other Loan Document or any other agreement, instrument or document or (v) the satisfaction of any condition set forth in Section 7 [Conditions of Lending and Issuance of Letters of Credit] or elsewhere herein, other than to confirm receipt of items expressly required to be delivered to the Agent.

10.4    Reliance by Agent. The Agent shall be entitled to rely upon, and shall not incur any liability for relying upon, any notice, request, certificate, consent, statement, instrument, document or other writing (including any electronic message, Internet or intranet website posting or other distribution) believed by it to be genuine and to have been signed, sent or otherwise authenticated by the proper Person. The Agent also may rely upon any statement made to it orally or by telephone and believed by it to have been made by the proper Person, and shall not incur any liability for relying thereon. In determining compliance with any condition hereunder to the making of a Loan, or the issuance of a Letter of Credit, that by its terms must be fulfilled to the satisfaction of a Bank or the Issuing Bank, the Agent may presume that such condition is satisfactory to such Bank or the Issuing Bank unless the Agent shall have received notice to the contrary from such Bank or the Issuing Bank prior to the making of such Loan or the issuance of such Letter of Credit. The Agent may consult with legal counsel (who may be counsel for the Borrower), independent accountants and other experts selected by it, and shall not be liable for any action taken or not taken by it in accordance with the advice of any such counsel, accountants or experts.

10.5    Delegation of Duties. The Agent may perform any and all of its duties and exercise its rights and powers hereunder or under any other Loan Document by or through any one or more sub‑agents appointed by the Agent. The Agent and any such sub‑agent may perform any and all of its duties and exercise its rights and powers by or through their respective Related Parties. The exculpatory provisions of this Section 10 shall apply to any such sub‑agent and to the Related Parties of the Agent and any such sub‑agent, and shall apply to their respective activities in connection with the syndication of the credit facilities provided for herein as well as activities as Agent.

10.6    Resignation of Agent. The Agent may at any time give notice of its resignation to the Banks, the Issuing Bank and the Borrower. Upon receipt of any such notice of resignation, the Required Banks shall have the right, with approval from the Borrower (so long as no Event of Default has occurred and is continuing), to appoint a successor, such approval not to be unreasonably withheld or delayed. If no such successor shall have been so appointed by the Required Banks and shall have accepted such appointment within thirty (30) days after the retiring Agent gives notice of its resignation, then the retiring Agent may on behalf of the Banks and the Issuing Bank, appoint a successor Agent; provided that if the Agent shall notify the Borrower and the Banks that no qualifying Person has accepted such appointment, then such resignation shall nonetheless become effective in accordance with such notice and (i) the retiring Agent shall be discharged from its duties and obligations hereunder and under the other Loan Documents (except that in the case of any collateral security held by the Agent on behalf of the Banks or the Issuing Bank under any of the Loan Documents, the retiring Agent shall continue to hold such collateral security until such time as a successor Agent is appointed) and (ii) all payments, communications and determinations provided to be made by, to or through the Agent shall instead be made by or to each Bank and the Issuing Bank directly, until such time as the Required Banks (with the approval of the Borrower, where applicable) appoint a successor Agent as provided for above in this Section 10.6. Upon the acceptance of a successor's appointment as Agent hereunder, such successor shall succeed to and become vested with all of the rights, powers, privileges and duties of the retiring (or retired) Agent, and the retiring Agent shall be discharged from all of its duties and obligations hereunder or under the other Loan Documents (if not already discharged therefrom as provided above in this Section). The fees payable by the

119

Table of Contents

Borrower to a successor Agent shall be the same as those payable to its predecessor unless otherwise agreed between the Borrower and such successor. After the retiring Agent's resignation hereunder and under the other Loan Documents, the provisions of this Section 10 and Section 11.3 [Expenses; Indemnity; Damage Waiver] shall continue in effect for the benefit of such retiring Agent, its sub‑agents and their respective Related Parties in respect of any actions taken or omitted to be taken by any of them while the retiring Agent was acting as Agent.

If PNC resigns as Agent under this Section 10.6, PNC shall also resign as an Issuing Bank. Upon the appointment of a successor Agent hereunder, such successor shall (i) succeed to all of the rights, powers, privileges and duties of PNC as the retiring Issuing Bank and Agent and PNC shall be discharged from all of its respective duties and obligations as Issuing Bank and Agent under the Loan Documents, and (ii) issue letters of credit in substitution for the Letters of Credit issued by PNC, if any, outstanding at the time of such succession or make other arrangement satisfactory to PNC to effectively assume the obligations of PNC with respect to such Letters of Credit.

10.7    Non-Reliance on Agent and Other Banks. Each Bank and the Issuing Bank acknowledges that it has, independently and without reliance upon the Agent or any other Bank or any of their Related Parties and based on such documents and information as it has deemed appropriate, made its own credit analysis and decision to enter into this Agreement. Each Bank and the Issuing Bank also acknowledges that it will, independently and without reliance upon the Agent or any other Bank or any of their Related Parties and based on such documents and information as it shall from time to time deem appropriate, continue to make its own decisions in taking or not taking action under or based upon this Agreement, any other Loan Document or any related agreement or any document furnished hereunder or thereunder.

10.8    No Other Duties, etc. Anything herein to the contrary notwithstanding, no other agent listed on the cover page hereof shall have any powers, duties or responsibilities under this Agreement or any of the other Loan Documents, except in its capacity, as applicable, as the Agent, a Bank or the Issuing Bank hereunder.

10.11    No Reliance on Agent's Customer Identification Program. Each Bank acknowledges and agrees that neither such Bank, nor any of its Affiliates, participants or assignees, may rely on the Agent to carry out such Bank's, Affiliate's, participant's or assignee's customer identification program, or other obligations required or imposed under or pursuant to

120

11.2    No Implied Waivers; Cumulative Remedies. No course of dealing and no delay or failure of the Agent or any Bank in exercising any right, power, remedy or privilege under this Agreement or any other Loan Document shall affect any other or future exercise thereof or operate as a waiver thereof, nor shall any single or partial exercise thereof preclude any further exercise thereof or of any other right, power, remedy or privilege.

(v)    No Assignment to Borrower. No such assignment shall be made to the Borrower or any of the Borrower's Affiliates or Subsidiaries.

(vi)    No Assignment to Natural Persons. No such assignment shall be made to a natural person.

Subject to acceptance and recording thereof by the Agent pursuant to Section 11.9.3 [Register], from and after the effective date specified in each Assignment and Assumption Agreement, the assignee thereunder shall be a party to this Agreement and, to the extent of the interest assigned by such Assignment and Assumption Agreement, have the rights and obligations of a Bank under this Agreement, and the assigning Bank thereunder shall, to the extent of the interest assigned by such Assignment and Assumption Agreement, be released from its obligations under this Agreement (and, in the case of an Assignment and Assumption Agreement covering all of the assigning Bank's rights and obligations under this Agreement, such Bank shall cease to be a party hereto) but shall continue to be entitled to the benefits of Sections 4.4 [LIBOR Rate Unascertainable; Etc.], 5.8 [Increased Costs], and 11.3 [Expenses, Indemnity; Damage Waiver] with respect to facts and circumstances occurring prior to the effective date of such assignment. Any assignment or transfer by a Bank of rights or obligations under this Agreement that does not comply with this Section 11.9.2 shall be treated for purposes of this Agreement as a sale by such Bank of a participation in such rights and obligations in accordance with Section 11.9.4 [Participations].

11.9.3    Register. The Agent, acting solely for this purpose as an agent of the Borrower, shall maintain a record of the names and addresses of the Banks, and the Commitments of, and principal amounts of the Loans owing to, each Bank pursuant to the terms hereof from time to time. Such register shall be conclusive, and the Borrower, the Agent and the Banks may treat each Person whose name is in such register pursuant to the terms hereof as a Bank hereunder for all purposes of this Agreement, notwithstanding notice to the contrary. Such register shall be available for inspection by the Borrower and any Bank, at any reasonable time and from time to time upon reasonable prior notice.

11.9.4    Participations. Any Bank may at any time, without the consent of, or notice to, the Borrower or the Agent, sell participations to any Person (other than a natural person or the Borrower or any of the Borrower's Affiliates or Subsidiaries) (each, a "Participant") in all or a portion of such Bank's rights and/or obligations under this Agreement (including all or a portion of its Commitment and/or the Loans owing to it); provided that (i) such Bank's obligations under this Agreement shall remain unchanged, (ii) such Bank shall remain solely responsible to the

127

Table of Contents

other parties hereto for the performance of such obligations and (iii) the Borrower, the Agent, the Banks, and the Issuing Bank shall continue to deal solely and directly with such Bank in connection with such Bank's rights and obligations under this Agreement.

Any agreement or instrument pursuant to which a Bank sells such a participation shall provide that such Bank shall retain the sole right to enforce this Agreement and to approve any amendment, modification or waiver of any provision of this Agreement; provided that such agreement or instrument may provide that such Bank will not, without the consent of the Participant, agree to any amendment, modification or waiver with respect to Sections 11.1.1 [Increase of Commitment], 11.1.2 [Extension of Payment, Etc.], or 11.1.3 [Release of Collateral or Guarantor]) that affects such Participant. The Borrower agrees that each Participant shall be entitled to the benefits of Sections 4.4 [LIBOR Rate Unascertainable, Etc.], 5.8 [Increased Costs], 5.10 [Indemnity] and 5.9 [Taxes] (subject to the requirements and limitations therein, including the requirements under Section 5.9.7 [Status of Banks] (it being understood that the documentation required under Section 5.9.7 [Status of Banks] shall be delivered to the participating Bank)) to the same extent as if it were a Bank and had acquired its interest by assignment pursuant to Section 11.8.2 [Assignments by Banks]; provided that such Participant (A) agrees to be subject to the provisions of Section 5.6.2 [Replacement of a Bank] as if it were an assignee under Section 11.9.2 [Assignments by Banks]; and (B) shall not be entitled to receive any greater payment under Sections 5.8 [Increased Costs] or 5.9 [Taxes], with respect to any participation, than its participating Bank would have been entitled to receive, except to the extent such entitlement to receive a greater payment results from a Change in Law that occurs after the Participant acquired the applicable participation. Each Bank that sells a participation agrees, at the Borrower's request and expense, to use reasonable efforts to cooperate with the Borrower to effectuate the provisions of Section 5.6.2 [Replacement of a Bank] with respect to any Participant. To the extent permitted by Law, each Participant also shall be entitled to the benefits of Section 9.2.3 [Set-off] as though it were a Bank; provided that such Participant agrees to be subject to Section 5.3 [Sharing of Payments by Banks] as though it were a Bank. Each Bank that sells a participation shall, acting solely for this purpose as an agent of the Borrower, maintain a register on which it enters the name and address of each Participant and the principal amounts (and stated interest) of each Participant's interest in the Loans or other obligations under the Loan Documents (the "Participant Register"); provided that no Bank shall have any obligation to disclose all or any portion of the Participant Register (including the identity of any Participant or any information relating to a Participant's interest in any commitments, loans, letters of credit or its other obligations under any Loan Document) to any Person except to the extent that such disclosure is necessary to establish that such commitment, loan, letter of credit or other obligation is in registered form under Section 5f.103-1(c) of the United States Treasury Regulations. The entries in the Participant Register shall be conclusive absent manifest error, and such Bank shall treat each Person whose name is recorded in the Participant Register as the owner of such participation for all purposes of this Agreement notwithstanding any notice to the contrary. For the avoidance of doubt, the Agent (in its capacity as Agent) shall have no responsibility for maintaining a Participant Register.

11.9.5    Certain Pledges; Successors and Assigns Generally. Any Bank may at any time pledge or assign a security interest in all or any portion of its rights under this Agreement to secure obligations of such Bank, including any pledge or assignment to secure obligations to a Federal Reserve Bank; provided that no such pledge or assignment shall release such Bank from
