2.10.3.4                                             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 2.10.3.2, 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 Agent a borrowing (each a “Letter of Credit Borrowing”) in Dollars in the Dollar Equivalent amount of such drawing.  Such Letter of Credit Borrowing shall be due and payable on demand (together with

36

interest) and shall bear interest at the rate per annum applicable to the Revolving Credit Loans under the Base Rate Option.  Each Lender’s payment to the Agent pursuant to Section 2.10.3.3 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 Lender in satisfaction of its participation obligation under this Section 2.10.3.

2.10.4                  Repayment of Participation Advances.

2.10.4.5                                             Upon (and only upon) receipt by the Agent for its account of immediately available funds from the Borrower (i) in reimbursement of any payment made by the Agent under the Letter of Credit with respect to which any Lender has made a Participation Advance to the Agent, or (ii) in payment of interest on such a payment made by the Agent under such a Letter of Credit, the Agent will pay to each Lender, in the same funds as those received by the Agent, the amount of such Lender’s Ratable Share of such funds, except the Agent shall retain the amount of the Ratable Share of such funds of any Lender that (a) did not make a Participation Advance in respect of such payment by Agent, or (b) is a Defaulting Lender in such latter case, up to the amount by which such Defaulting Lender has defaulted.

2.10.4.6                                             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 or otherwise, any portion of the payments made by any Loan Party to the Agent pursuant to Section 2.10.4.5 in reimbursement of a payment made under the Letter of Credit or interest or fee thereon, each Lender shall, on demand of the Agent, forthwith return to the Agent 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 Lender to the Agent, at a rate per annum equal to the Federal Funds Effective Rate in effect from time to time.

Each Loan Party agrees to be bound by the terms of the Agent’s application and agreement for letters of credit and the Agent’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, as determined by a final non-appealable judgment of a court of competent jurisdiction, the Agent 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.

2.10.6                  Determinations to Honor Drawing Requests.

In determining whether to honor any request for drawing under any Letter of Credit by the beneficiary thereof, the Agent 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.

(ix)                                any adverse change in the business, operations, properties, assets, condition (financial or otherwise) or prospects of any Loan Party or Subsidiaries of a Loan Party;

In addition to amounts payable as provided in Section 10.8 [Reimbursement and Indemnification of Agent by Borrower], the Borrower hereby agrees to protect, indemnify, pay and save harmless the Agent and any of Agent’s Affiliates that has issued a Letter of Credit from and against any and all claims, demands, liabilities, damages, taxes, penalties, interest, judgments, losses, costs, charges and expenses (including reasonable fees, expenses and disbursements of counsel and allocated costs of internal counsel) which the Agent or any of Agent’s Affiliates may incur or be subject to as a consequence, direct or indirect, of the issuance of any Letter of Credit, other than as a result of (i) the gross negligence, bad faith, or willful misconduct of the Agent as determined by a final judgment of a court of competent jurisdiction or (ii) the wrongful dishonor by the Agent or any of Agent’s Affiliates of a proper demand for payment made under any Letter of Credit, except if such dishonor resulted from any act or omission, whether rightful or wrongful, of any present or future de jure or de facto government or governmental authority (all such acts or omissions herein called “Governmental Acts”).

39

2.10.9                  Liability for Acts and Omissions.

As between any Loan Party and the Agent, or the Agent’s Affiliates, such Loan Party assumes all risks of the acts and omissions of, or misuse of the Letters of Credit by, the respective beneficiaries of such Letters of Credit.  In furtherance and not in limitation of the foregoing, the Agent shall not be responsible for any of the following including any losses or damages to any Loan Party or other Person or property relating therefrom:  (i) the form, validity, sufficiency, accuracy, genuineness or legal effect of any document submitted by any party in connection with the application for an issuance of any such Letter of Credit, even if it should in fact prove to be in any or all respects invalid, insufficient, inaccurate, fraudulent or forged (even if the Agent or the Agent’s Affiliates shall have been notified thereof); (ii) the validity or sufficiency of any instrument transferring or assigning or purporting to transfer or assign any such Letter of Credit or the rights or benefits thereunder or proceeds thereof, in whole or in part, which may prove to be invalid or ineffective for any reason; (iii) the failure of the beneficiary of any such Letter of Credit, or any other party to which such Letter of Credit may be transferred, to comply fully with any conditions required in order to draw upon such Letter of Credit or any other claim of any Loan Party against any beneficiary of such Letter of Credit, or any such transferee, or any dispute between or among any Loan Party and any beneficiary of any Letter of Credit or any such transferee; (iv) errors, omissions, interruptions or delays in transmission or delivery of any messages, by mail, cable, telegraph, telex or otherwise, whether or not they be in cipher; (v) errors in interpretation of technical terms; (vi) any loss or delay in the transmission or otherwise of any document required in order to make a drawing under any such Letter of Credit or of the proceeds thereof; (vii) the misapplication by the beneficiary of any such Letter of Credit of the proceeds of any drawing under such Letter of Credit; or (viii) any consequences arising from causes beyond the control of the Agent or the Agent’s Affiliates, as applicable, including any Governmental Acts, and none of the above shall affect or impair, or prevent the vesting of, any of the Agent’s or the Agent’s Affiliates rights or powers hereunder.  Nothing in the preceding sentence shall relieve the Agent from liability for the Agent’s bad faith, gross negligence or willful misconduct in connection with actions or omissions described in such clauses (i) through (viii) of such sentence, as determined by a final non-appealable judgment of a court of competent jurisdiction.  In no event shall the Agent or the Agent’s Affiliates be liable to any Loan Party for any indirect, consequential, incidental, punitive, exemplary or special damages or expenses (including without limitation attorneys’ fees), or for any damages resulting from any change in the value of any property relating to a Letter of Credit.

Without limiting the generality of the foregoing, the Agent and each of its Affiliates (a) may rely on any oral or other communication believed in good faith by the Agent or such Affiliate to have been authorized or given by or on behalf of the applicant for a Letter of Credit, (b) may honor any presentation if the documents presented appear on their face substantially to comply with the terms and conditions of the relevant Letter of Credit; (c) may honor a previously dishonored presentation under a Letter of Credit, whether such dishonor was pursuant to a court order, to settle or compromise any claim of wrongful dishonor, or otherwise, and shall be entitled to reimbursement to the same extent as if such presentation had initially been honored, together with any interest paid by the Agent or its Affiliate; (d) may honor any drawing that is payable upon presentation of a statement advising negotiation or payment, upon receipt of such statement (even if such statement indicates that a draft or other document is being

40

delivered separately), and shall not be liable for any failure of any such draft or other document to arrive, or to conform in any way with the relevant Letter of Credit; (e) may pay any paying or negotiating bank claiming that it rightfully honored under the laws or practices of the place where such bank is located; and (f) may settle or adjust any claim or demand made on the Agent or its Affiliate in any way related to any order issued at the applicant’s request to an air carrier, a letter of guarantee or of indemnity issued to a carrier or any similar document (each an “Order”) and honor any drawing in connection with any Letter of Credit that is the subject to such Order, notwithstanding that any drafts or other documents presented in connection with such Letter of Credit fail to conform in any way with such Letter of Credit.

In furtherance and extension and not in limitation of the specific provisions set forth above, any action taken or omitted by the Agent or the Agent’s Affiliates under or in connection with the Letters of Credit issued by it or any documents and certificates delivered thereunder, if taken or omitted in good faith, shall not put the Agent or the Agent’s Affiliates under any resulting liability to the Borrower or any Lender.

2.10.10            Cash Collateral.

Upon the request of the Agent, if, on the Expiration Date, any Letter of Credit Obligation for any reason remains outstanding, the Borrower shall immediately Cash Collateralize the then outstanding amount of all Letter of Credit Obligations. The Borrower hereby grants to the Agent, for the benefit of the Agent and the Lenders, a security interest in all cash collateral pledged pursuant to this Section or otherwise under this Agreement.

2.11                          Utilization of Commitments in Optional Currencies.

2.11.1                  Periodic Computations of Dollar Equivalent Amounts of Loans and Letters of Credit Outstanding.

The Agent will determine the Dollar Equivalent amount of (i) proposed Revolving Credit Loans or Letters of Credit to be denominated in an Optional Currency as of the requested Borrowing Date or date of issuance, as the case may be, and (ii) outstanding Revolving Credit Loans denominated in an Optional Currency as of the end of each Interest Period (each such date under clauses (i) and (ii), a “Computation Date”).

2.11.2                  Notices From Lenders That Optional Currencies Are Unavailable to Fund New Loans.

The Lenders shall be under no obligation to make the Revolving Credit Loans requested by the Borrower which are denominated in an Optional Currency if any Lender notifies the Agent by 5:00 p.m. (Pittsburgh time) four (4) Business Days prior to the Borrowing Date for such Revolving Credit Loans that such Lender cannot provide its share of such Revolving Credit Loans in such Optional Currency due to the introduction of, or any change in, any applicable Law or any change in the interpretation or administration thereof by any Official Body charged with the administration or interpretation thereof, or compliance by such Lender (or any of its lending offices) with any request or directive (whether or not having the force of Law)

41

of any such Official Body which would make it unlawful or impossible for such Lender (or any of its lending offices) to honor its obligations to make a Loan in an Optional Currency.  In the event the Agent timely receives a notice from a Lender pursuant to the preceding sentence, the Agent will notify the Borrower no later than 12:00 noon (Pittsburgh time) three (3) Business Days prior to the Borrowing Date for such Revolving Credit Loans that the Optional Currency is not then available for such Revolving Credit Loans, and the Agent shall promptly thereafter notify the Lenders of the same.  If the Borrower receives a notice described in the preceding sentence, the Borrower may, by notice to the Agent not later than 5:00 p.m. (Pittsburgh time) three (3) Business Days prior to the Borrowing Date for such Revolving Credit Loans, withdraw the Loan Request for such Revolving Credit Loans.  If the Borrower withdraws such Loan Request, the Agent will promptly notify each Lender of the same and the Lenders shall not make such Revolving Credit Loans.  If the Borrower does not withdraw such Loan Request before such time, (i) the Borrower shall be deemed to have requested that the Revolving Credit Loans referred to in its Loan Request shall be made in Dollars in an amount equal to the Dollar Equivalent amount of such Revolving Credit Loans and shall bear interest under the Base Rate Option, and (ii) the Agent shall promptly deliver a notice to each Lender stating: (a) that such Revolving Credit Loans shall be made in Dollars and shall bear interest under the Base Rate Option, (b) the aggregate amount of such Revolving Credit Loans, and (c) such Lender’s Ratable Share of such Revolving Credit Loans.

2.11.3                Notices From Lenders That Optional Currencies Are Unavailable to Fund Renewals of the Euro-Rate Option.

If the Borrower delivers a Loan Request requesting that the Lenders renew the Euro-Rate Option with respect to an outstanding Borrowing Tranche of Revolving Credit Loans denominated in an Optional Currency, the Lenders shall be under no obligation to renew such Euro-Rate Option if any Lender delivers to the Agent a notice by 5:00 p.m. (Pittsburgh time) four (4) Business Days prior to effective date of such renewal that such Lender cannot continue to provide Revolving Credit Loans in such Optional Currency due to the introduction of, or any change in, any applicable Law or any change in the interpretation or administration thereof by any Official Body charged with the administration or interpretation thereof, or compliance by such Lender (or any of its lending offices with) any request or directive (whether or not having the force of Law) of any such Official Body which would make it unlawful or impossible for such Lender (or any of its lending offices) to honor its obligations to make a Loan in an Optional Currency.  In the event the Agent timely receives a notice from a Lender pursuant to the preceding sentence, the Agent will notify the Borrower no later than 12:00 noon (Pittsburgh time) three (3) Business Days prior to the renewal date that the renewal of such Revolving Credit Loans in such Optional Currency is not then available, and the Agent shall promptly thereafter notify the Lenders of the same.  If the Agent shall have so notified the Borrower that any such continuation of Optional Currency Loans is not then available, any notice of renewal with respect thereto shall be deemed withdrawn, and such Optional Currency Loans shall be redenominated into Loans in Dollars subject to the Base Rate Option with effect from the last day of the Interest Period with respect to any such Optional Currency Loans.  The Agent will promptly notify the Borrower and the Lenders of any such redenomination, and in such notice, the Agent will state the aggregate Dollar Equivalent amount of the redenominated

42

Optional Currency Loans as of the Computation Date with respect thereto and such Lender’s Ratable Share thereof.

2.11.4                  European Monetary Union.

2.11.4.1                                          Payments In Euros Under Certain Circumstances.

If, as a result of the implementation of the European monetary union, (i) any Optional Currency ceases to be lawful currency of the nation issuing the same and is replaced by a European common currency (the “Euro”) or (ii) any Optional Currency and the Euro are at the same time recognized by any governmental authority of the nation issuing such currency as lawful currency of such nation and the Agent or the Required Lenders shall so request in a notice delivered to the Borrower, then any amount payable hereunder by any part hereto in such Optional Currency shall instead by payable in the Euro and the amount so payable shall be determined by translating the amount payable in such Optional Currency to the Euro at the exchange rate recognized by the European Central Lender for the purpose of implementing the European monetary union (and the provisions governing payments in Optional Currencies in this Agreement shall apply to such payment in the Euro as if such payment in the Euro were a payment in an Optional Currency).  Prior to the occurrence of the event or events described in clause (i) or (ii) of the preceding sentence, each amount payable hereunder in any Optional Currency will continue to be payable only in that currency, except as otherwise provided herein.

2.11.4.2                                          Additional Compensation Under Certain Circumstances.

The Borrower agrees, at the request of any Lender to compensate such Lender for any loss, cost, expense or reduction in return that such Lender shall reasonably determine shall be incurred or sustained by such Lender as a result of the implementation of European monetary union and that would not have been incurred or sustained but for the transactions provided for herein.  A certificate of any Lender setting forth such Lender’s determination of the amount or amounts necessary to compensate such Lender shall be delivered to the Borrower and shall be conclusive absent manifest error so long as such determination is made on a reasonable basis.  The Borrower shall pay such Lender the amount shown as due on any such certificate within ten (10) days after receipt thereof.

2.11.5                  Requests for Additional Optional Currencies.

The Borrower may deliver to the Agent a written request that Revolving Credit Loans hereunder also be permitted to be made in any other lawful currency (other than Dollars), in addition to the currencies specified in the definition of “Optional Currency” herein provided that such currency must be freely traded in the offshore interbank foreign exchange markets, freely transferable, freely convertible into Dollars and available to the Lenders in the applicable interbank market.  The Agent will promptly notify the Lenders of any such request promptly after the Agent receives such request.  The Agent and each Lender may grant or accept such request in their sole discretion.  The Agent will promptly notify the Borrower of the acceptance or rejection by the Agent and each of the Lenders of the Borrower’s

43

request.  The requested currency shall be approved as an Optional Currency hereunder only if the Agent and all of the Lenders approve of the Borrower’s request.

2.12                          Currency Repayments.

Notwithstanding anything contained herein to the contrary, the entire amount of principal of and interest on any Loan made in an Optional Currency shall be repaid in the same Optional Currency in which such Loan was made, provided, however, that if it is impossible or illegal for the Borrower to effect payment of a Loan in the Optional Currency in which such Loan was made, or if the Borrower defaults in its obligations to do so, the Required Lenders may at their option permit such payment to be made (i) at and to a different location, subsidiary, affiliate or correspondent of Agent, or (ii) in the Equivalent Amount of Dollars or (iii) in an Equivalent Amount of such other currency (freely convertible into Dollars) as the Required Lenders may solely at their option designate.  Upon any events described in (i) through (iii) of the preceding sentence, the Borrower shall make such payment and Borrower agrees to hold each Lender harmless from and against any loss incurred by any Lender arising from the cost to such Lender of any premium, any costs of exchange, the cost of hedging and covering the Optional Currency in which such Loan was originally made, and from any change in the value of Dollars, or such other currency, in relation to the Optional Currency that was due and owing.  Such loss shall be calculated for the period commencing with the first day of the Interest Period for such Loan and continuing through the date of payment thereof.  Without prejudice to the survival of any other agreement of Borrower hereunder, Borrower’s obligations under this Section 2.12 shall survive termination of this Agreement.

2.13                          Optional Currency Amounts.

Notwithstanding anything contained herein to the contrary, the Agent may, with respect to notices by the Borrower for Loans in an Optional Currency or voluntary prepayments of less than the full amount of an Optional Currency Borrowing Tranche, engage in reasonable rounding of the Optional Currency amounts requested to be loaned or repaid; and, in such event, the Agent shall promptly notify the Borrower and the Lenders of such rounded amounts and the Borrower’s request or notice shall thereby be deemed to reflect such rounded amounts.

2.14                          Right to Increase Revolving Credit Commitments.

Provided that there is no Event of Default or Potential Default, if the Borrower wishes to increase the Revolving Credit Commitments, the Borrower shall notify the Agent thereof, provided that any such increase shall be in a minimum of $10,000,000.00 and the aggregate of all such increases in the Revolving Credit Commitments shall not exceed $50,000,000.00 from and after the Closing Date.  Each Lender shall have the right at any time within fifteen (15) Business Days following such notice to increase its respective Revolving Credit Commitment so as to provide such added commitment pro rata in accordance with such Lender’s Ratable Share, and any portion of such requested increase that is not provided by any Lender shall: (i) first be available to the other Lenders pro rata in accordance with their Ratable Share, (ii) next be available to the other Lenders in such a manner as the Borrower, the Agent and those Lenders shall agree, and (iii) thereafter, to the extent not provided by the Lenders, to any

44

additional lender proposed by the Borrower, which is approved by the Agent (which approval shall not be unreasonably withheld) and that becomes a party to this Agreement pursuant to Section 11.11 [Successors and Assigns]. In the event of any such increase in the aggregate Revolving Credit Commitments effected pursuant to the terms of this Section 2.14, new Revolving Credit Notes shall, to the extent necessary, be executed and delivered by the Borrower in exchange for the surrender of the existing Revolving Credit Notes and the Agent shall amend Schedule 1.1(B) to reflect any additional Lender(s) and any change in Lenders’ Ratable Shares.

3.             [Intentionally Omitted.]

4.             INTEREST RATES

4.1                                Interest Rate Options.

The Borrower shall pay interest in respect of the outstanding unpaid principal amount of the Revolving Credit Loans as selected by it from the Base Rate Option or Euro-Rate Option set forth below applicable to the Revolving Credit 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 Revolving Credit 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 Revolving Credit Loans comprising any Borrowing Tranche, provided that there shall not be at any one time outstanding more than six (6) Borrowing Tranches in the aggregate among all of the Revolving Credit Loans, and provided further that Swing Loans shall bear interest at such rate, based upon the Base Rate, determined from time to time by PNC Bank.  If at any time the designated rate applicable to any Loan made by any Lender exceeds such Lender’s highest lawful rate, the rate of interest on such Lender’s Loan shall be limited to such Lender’s highest lawful rate. Interest on the principal amount of each Loan made in an Optional Currency as provided in Section 2.11.4, shall be paid by the Borrower in such Optional Currency.

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), except that no Loan to which a Base Rate shall apply may be made in an Optional Currency:

(i)                                     Revolving Credit Base Rate Option:  A fluctuating rate per annum (computed on the basis of a year of 360 days, and actual days elapsed, provided that, for Loans made in an Optional Currency for which a 365 day basis is the only market practice available to the Agent, such rate shall be calculated on the basis of a year of 365 days, for the actual days) equal to the Base Rate plus the Applicable Margin, such interest rate to change automatically from time to time effective as of the effective date of each change in the Base Rate or Applicable Margin; or

45

(ii)                                  Revolving Credit Euro-Rate Option:  A rate per annum (computed on the basis of a year of 360 days and actual days elapsed, provided that, for Loans made in an Optional Currency for which a 365 day basis is the only market practice available to the Agent, such rate shall be calculated on the basis of a year of 365 days, for the actual days) equal to the Euro-Rate plus the Applicable Margin, such interest rate to change automatically from time to time effective as of the effective date of each change in Applicable Margin.

4.1.2                        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 interest rates and the applicable currency exchange rates then in effect, but it is acknowledged that such projection shall not be binding on the Agent or the Lenders nor affect the rate of interest or the calculation of Equivalent Amounts which thereafter are 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 Euro-Rate Option, the Borrower shall notify the Agent thereof by delivering a Loan Request no later than 11:00 a.m. (Pittsburgh time) at least (i) four (4) Business Days prior to the effective date of such Interest Rate Option, with respect to an Optional Currency Loan, and (ii) three (3) Business Days prior to the effective date of such Interest Rate Option with respect to a Dollar Loan. 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 Euro-Rate Option:

4.2.1                        Amount of Borrowing Tranche.

The Dollar Equivalent amount of each Borrowing Tranche of Euro-Rate Loans shall be in integral multiples of $1,000,000.00 and not less than $5,000,000.00; and

4.2.2                        Renewals.

In the case of the renewal of a Euro-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:

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 2.10.2 [Letter of Credit Fees] or Section 4.1 [Interest Rate Options], respectively, shall be increased by 2.0% per annum; and

46

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 Interest Rate Option plus an additional two percent (2%) 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 Lenders are entitled to additional compensation for such risk; and all such interest shall be payable by Borrower upon demand by Agent.

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

4.4.1                        Unascertainable.

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

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

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

4.4.2                        Illegality; Increased Costs; Deposits Not Available.

If at any time any Lender shall have determined that:

(i)                                     the making, maintenance or funding of any Loan to which a Euro-Rate Option applies has been made impracticable or unlawful by compliance by such Lender in good faith with the adoption of any change in any Law or any interpretation or application thereof occurring after the Closing Date 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 Euro-Rate Option will not adequately and fairly reflect the cost to such Lender of the establishment or maintenance of any such Loan, or

(iii)                               after making all reasonable efforts, deposits of the relevant amount in Dollars or in the Optional Currency (as applicable) for the relevant Interest Period for a Loan, or to banks generally, to which a Euro-Rate Option applies, respectively, are not

47

available to such Lender 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 Lender’s Rights].

4.4.3                        Agent’s and Lender’s Rights.

In the case of any event specified in Section 4.4.1 [Unascertainable] above, the Agent shall promptly so notify the Lenders 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 Lender 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 Lenders 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 (i) the Lenders, in the case of such notice given by the Agent, or (ii) such Lender, in the case of such notice given by such Lender, to allow the Borrower to select, convert to or renew a Euro-Rate Option or select an Optional Currency (as applicable) shall be suspended until the Agent shall have later notified the Borrower, or such Lender shall have later notified the Agent, of the Agent’s or such Lender’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 Euro-Rate Option and such Interest Rate Option has not yet gone into effect, such notification shall be deemed to provide for the selection of, conversion to or renewal of the Base Rate Option otherwise available with respect to such Loans.  If any Lender 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 5.7 [Indemnity], as to any Loan of the Lender to which a Euro-Rate Option applies, on the date specified in such notice either, as applicable, (a) convert such Loan to the Base Rate Option otherwise available with respect to such Loan, or select a different Optional Currency or Dollars, or (b) prepay such Loan in accordance with Section 5.4 [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.

4.5                                 Selection of Interest Rate Options.

If the Borrower fails to select a new Interest Period or Optional Currency to apply to any Borrowing Tranche of Loans under the Euro-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 or to a Dollar Loan, as applicable, commencing upon the last day of the existing Interest Period.
