(d)    Promptly following receipt of an Interest Election Request, the Administrative Agent shall advise each Lender of the relevant Class of the details thereof and of such Lender’s portion of each resulting Borrowing.

(e)    If the Borrower fails to deliver a timely Interest Election Request with respect to a

Eurodollar Borrowing prior to the end of the Interest Period applicable thereto, then, unless such Borrowing is repaid as provided herein, at the end of such Interest Period such Borrowing shall be converted to an ABR Borrowing. Notwithstanding any contrary provision hereof, if an Event of Default has occurred and is continuing and the Administrative Agent, at the request of the Required Lenders, so notifies the Borrower (or, in the case of an Event of Default of the type described in paragraph (i) or (j) of Article 7 with respect to the Borrower, automatically), then, so long as an Event of Default has occurred and is continuing, no outstanding Borrowing may be converted to or continued as a Eurodollar Borrowing having an Interest Period longer than one month; provided that, if (x) an Event of Default of the type described in paragraph (a), (b), (i) or (j) of Article 7 has occurred and is continuing and (y) other than in the case of an Event of Default of the type described in paragraph (i) or (j) of Article 7 with respect to the Borrower, the Required Lenders have so requested, then (i) no outstanding Borrowing may be converted to or continued as a Eurodollar Borrowing and (ii) unless repaid prior to or at the end of the Interest Period then applicable thereto, each Eurodollar Borrowing shall be converted to an ABR Borrowing at the end of such Interest Period.

(a) The Borrower hereby unconditionally promises to pay to the Administrative Agent (i) for the account of each Revolving Lender the then unpaid principal amount of such Lender’s Revolving Loans on the Revolving Maturity Date and (ii) for the account of each Term Lender the then unpaid principal amount of such Lender’s Term Loans as provided in Section 2.09.

(e)Any Lender may request that Loans of any Class made by it be evidenced by a promissory note. In such event, the Borrower shall prepare, execute and deliver to such Lender a promissory note payable to such Lender (or, if requested by such Lender, to such Lender and its registered assigns) and in a form approved by the Administrative Agent; provided that, in order for any such promissory note to be delivered on the Sixth ARCA Effective Date, the Tranche B-6 Refinancing and Incremental Amendment Effective Date or, the Second Tranche B-6 Incremental Amendment Effective Date or the Tranche B-7 Refinancing Amendment Effective Date, the request therefor shall be delivered no later than two Business Days prior to the Sixth ARCA Effective Date, the Tranche B-6 Refinancing and Incremental Amendment Effective Date or, the Second Tranche B-6 Incremental Amendment Effective Date or the Tranche B-7 Refinancing Amendment Effective Date, as applicable. 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).

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.

(g) Optional Prepayment of Tranche B-6 Term Loans.

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.

SECTION 5.11. Further Assurances. (a) Each Loan Party will execute and deliver any and all further documents, financing statements, agreements and instruments, and take all such further actions (including the filing and recording of financing statements, fixture filings and other documents), that may be required under any applicable law, or that the Collateral Agent or the Required Lenders may reasonably request, to cause the Collateral and Guarantee Requirement to be and remain satisfied, all at the Borrower’s expense. The Borrower will provide to the Collateral Agent, from time to time upon any reasonable request from the Collateral Agent, evidence reasonably satisfactory to the Collateral Agent as to the perfection and priority of the Liens intended to be created by the Security Documents.

(b)    If any material assets (other than (i) any real property or improvements thereto or any interest therein, (ii) any RUS Grant Funds, (iii) any asset purchased with RUS Grant Funds and any proceeds thereof or (iv) Notes Escrowed Proceeds) are acquired by any Loan Party after the Sixth ARCA Effective Date (other than assets constituting Collateral that become subject to Transaction Liens upon acquisition thereof), the Borrower will notify the Collateral Agent thereof, and, if requested by the Collateral Agent or the Required Lenders, will cause such assets to be subjected to a Transaction Lien

(d)Further, notwithstanding anything to the contrary contained in this Section, if following the Sixth ARCA Effective Date, the Administrative Agent and the Borrower shall have jointly identified an obvious error or any error or omission of a technical or immaterial nature, in each case, in any provision of the Loan Documents then the Administrative Agent (acting in its sole discretion) and the Borrower shall be permitted to amend such provision and such amendment shall become effective without any further action or consent of any other party to any Loan Document if the same is not objected to in writing by the Required Lenders within five Business Days following receipt of notice thereof.
