Each notice delivered by the Borrower pursuant to this Section shall be irrevocable; provided that a notice of termination of the Revolving Commitments delivered by the Borrower may state that such notice is conditioned upon the occurrence or non-occurrence of any event specified therein (including the consummation of an acquisition, sale or other similar transaction, or the receipt of proceeds from the incurrence or issuance of Indebtedness or Equity Interests or the effectiveness of other credit facilities), in which case such notice may be revoked by the Borrower (by notice to the Administrative Agent on or prior to the specified effective date) if such condition is not satisfied. Any termination or reduction of the Commitments of any Class shall be permanent. Each reduction of the Commitments of any Class

maintain such accounts or any error therein shall not in any manner affect the obligation of the Borrower to repay the Loans in accordance with the terms of this Agreement.

(e)    Any Lender may request that Loans of any Class made by it be evidenced by a

Thereafter, the Loans evidenced by such promissory note and interest thereon shall at all times (including after assignment pursuant to Section 9.04) be represented by one or more promissory notes in such form payable to the payee named therein (or, if such promissory note is a registered note, to such payee and its registered assigns).

(c)    Any prepayment of Term Loans of any Class will be applied to reduce the subsequent scheduled repayments of the Term Loans of such Class to be made pursuant to this Section, in the case of mandatory prepayments, in direct order of maturity, and in the case of voluntary prepayments, ratably.

(d)    Before repaying any Term Loans of any Class pursuant to this Section, the Borrower shall select the Borrowing or Borrowings of the applicable Class to be repaid and shall notify the Administrative Agent by telephone (confirmed by telecopy) of such selection not later than 11:00 a.m., New York City time, three Business Days before the scheduled date of such repayment. Each such repayment of a Borrowing shall be applied ratably to the Loans included in such Borrowing and shall be accompanied by accrued interest on the amount repaid.

Before any optional or mandatory prepayment of Borrowings hereunder, the Borrower shall select the Borrowing or Borrowings to be prepaid and shall specify such selection in the notice of such prepayment pursuant to paragraph (h) of this Section. Optional prepayments shall be applied to such Classes of Term Loans as directed by the Borrower in the notice of prepayment, provided that such prepayments of any Class of Term Loan shall be applied in accordance with the second sentence of Section 2.10(i). In the event of any mandatory prepayment of Term Borrowings made at a time when Term Borrowings of more than one Class remain outstanding, the aggregate amount of such prepayment shall be allocated among the Term Borrowings of each Class pro rata based on the aggregate principal amount of outstanding Borrowings of each such Class, provided however that any Tranche B-5 Lender and any Tranche B-6 Lender may elect, by notice to the Administrative Agent by telephone (confirmed by telecopy) at least one Business Day prior to the prepayment date, to decline all or any portion of any prepayment of its Tranche B-5 Term Loans or its Tranche B-6 Term Loans, as applicable, pursuant to this Section (other than an optional prepayment pursuant to paragraph (a) of this Section which may not be declined), in which case the aggregate amount of the prepayment that would have been applied to prepay Term Loans of any such Class but was so declined shall be applied to prepay Term Borrowings of the other Classes on a ratable basis (subject to the rights of the Tranche B-5 Lenders and the Tranche B-6 Lenders to decline such payments as set forth in this proviso) until no Term Borrowings of any other Class remain outstanding. All optional or mandatory prepayments of Revolving Borrowings made at a time when Revolving Borrowings of more than one Class remain outstanding shall be allocated among the Revolving Borrowings of each Class pro rata based on the aggregate principal amount of outstanding Borrowings of each such Class. All optional or mandatory prepayments of a Revolving Borrowing shall be applied in accordance with the second sentence of Section 2.10(i).

(f)    Accrued Interest. Each prepayment of a Borrowing shall be accompanied by accrued interest to the extent required by Section 2.12.

purposes of the Wireline Companies. The proceeds of any Incremental Facility will be used only as provided in Section 2.01(i)(iii) and in the Incremental Facility Amendment. No part of the proceeds of any Loan or Letters of Credit will be used, whether directly or indirectly, to purchase or carry margin stock or to extend credit to others for the purpose of purchasing or carrying margin stock or for any other purpose, in each case that entails a violation of any of the Regulations of the Board, including Regulations T, U and X. Letters of Credit will be issued only to support general corporate obligations of the Wireline Companies. The proceeds of the Tranche B-6 Term Loans made on the Tranche B-6 Refinancing and Incremental Amendment Effective Date shall be utilized (i) to the extent constituting Other Term Loans, on the Tranche B-6 Refinancing and Incremental Amendment Effective Date, to refinance in full the Existing Tranche B-6 Term Loans and (ii) otherwise, (A) to redeem all or a portion of the 2017 Notes and to pay related fees and expenses and (B) for general corporate purposes, including without limitation, to refinance in full or in part any other series of outstanding notes of the Borrower or its subsidiaries and to pay related fees and expenses.

SECTION 5.10. Additional Subsidiaries. If any additional Subsidiary, other than an Insignificant Subsidiary, a Notes SPV or a Special Purpose Receivables Subsidiary, is formed or acquired after the Sixth ARCA Effective Date, the Borrower will, within ten Business Days after such Subsidiary is formed or acquired, notify the Administrative Agent and the Collateral Agent thereof and cause the Collateral and Guarantee Requirement to be satisfied with respect to any Equity Interest in such Subsidiary held by a Loan Party and any Indebtedness of such Subsidiary owed to a Loan Party. If at any time any Subsidiary that is not then a Loan Party, other than (A) an Insignificant Subsidiary, (B) prior to the PAETEC Notes Redemption Date, a Qualified PAETEC Group Member, (C) a Notes SPV, (D) any Subsidiary listed on Schedule 5.10 or (E) a Special Purpose Receivables Subsidiary, (x) is a wholly-owned Domestic Subsidiary and is permitted by applicable law or regulation (without the need to obtain any Governmental Authorization) to Guarantee the Facility Obligations or (y) Guarantees any Loan Party’s obligations in respect of any AC Holdings Bonds or any other Indebtedness (other than Indebtedness created under the Loan Documents), the Borrower shall promptly cause (A) such Subsidiary to Guarantee the Facility Obligations pursuant to the Guarantee Agreement (in the case of any Subsidiary described in clause (y), on terms no less favorable to the Lenders than those applicable under such Guarantee of other Indebtedness) and (B) the other provisions of the Collateral and Guarantee Requirement to be satisfied with respect to such Subsidiary, whereupon such Subsidiary will become a “Guarantor” and “Lien Grantor” for purposes of the Loan Documents. The Borrower will not, and will not permit any of its Subsidiaries to, form or acquire any Subsidiary (other than Insignificant Subsidiaries and other than (i) any Notes SPV, (ii) prior to the PAETEC Notes Redemption Date, any Qualified PAETEC Group Member and (iii) any Special Purpose Receivables Subsidiary) after the Sixth ARCA Effective Date unless either (x) all of the Equity Interests in such Subsidiary shall be directly held by a Loan Party or (y) such Subsidiary shall have Guaranteed the Facility Obligations pursuant to the Guarantee Agreement and shall have satisfied the other provisions of the Collateral and Guarantee Requirement with respect to such Subsidiary. Prior to the PAETEC Notes Redemption Date, the Borrower will not permit any PAETEC Group Member to form or acquire any Subsidiary except for the purpose of reorganizing the organizational structure or form of organization of any of the PAETEC Group Members. For the avoidance of doubt, from and after the PAETEC Notes Redemption Date, any Qualified PAETEC Group Member not previously subject to the requirements set forth in this Section 5.10 shall be subject to the requirements set forth in this Section 5.10 as if such Qualified PAETEC Group Member became a Subsidiary on such date.
