WHEREAS, Pledgor, the Collateral Agent and the lenders referred to therein, are parties to the Credit Agreement dated as of June 30, 2000 (as heretofore modified and supplemented and in effect on the date hereof, the “Existing Credit Agreement”) pursuant to which such lenders have made loans and extended other credit to Pledgor that remain outstanding on the date hereof. In connection with a proposed recapitalization of Pledgor, Pledgor, said lenders and certain other banks and financial institutions party thereto, and Rural Telephone Finance Cooperative, as Administrative Agent, are amending and restating in its entirety the Existing Credit Agreement pursuant to an Amended and Restated Credit Agreement dated as of the date hereof (as increased, modified and supplemented and in effect from time to time, the “Credit Agreement”), providing, subject to the terms and conditions thereof, for extensions of credit to be made by the Lenders (as defined in the Credit Agreement) to Pledgor in an original principal amount of up to $577,777,777, subject to increase as provided therein to $702,777,777. Pursuant to the Existing Credit Agreement, Pledgor and the Collateral Agent executed and delivered a Pledge and Security Agreement dated as of October 28, 2004 (as heretofore modified and supplemented and in effect on the date hereof, the “Existing Pledge Agreement”). In connection with the execution and delivery of the Credit Agreement, the parties hereto have agreed to modify the Existing Pledge Agreement in certain respects and, as so modified, to amend and restate the Existing Pledge Agreement in its entirety as provided herein; and

WHEREAS, the obligations of the Lenders (as defined therein) under the Credit Agreement to make Loans (as defined therein) and to issue Letters of Credit (as defined therein) are conditioned upon, among other things, the execution and delivery by Pledgor of this Agreement, amending and restating the Existing Pledge Agreement to pledge and grant to the Collateral Agent, for the ratable benefit of the Secured Parties (used herein as defined in the Security Agreement), a security interest in the Collateral (as hereinafter defined).

(b) The Collateral Agent in its discretion may, in its name or in the name of Pledgor or otherwise, demand, sue for, collect or receive any money or property at any time payable or receivable on account of or in exchange for any of the Collateral, but shall be under no obligation to do so; and

(c) The Collateral Agent may, upon ten (10) business days prior written notice to Pledgor of the time and place, with respect to the Collateral or any part thereof which shall then be or shall thereafter come into the possession, custody or control of the Collateral Agent or any of its agents, sell or otherwise dispose of all or any part of such Collateral, at such place or places as the Collateral Agent deems best, and for cash or on credit or for future delivery (without thereby assuming any credit risk), at public or private sale, without demand of performance or notice of intention to effect any such disposition or of time or place of sale (except such notice as is required above, or as is required by applicable statute and cannot be waived) and the Collateral Agent or anyone else may be the purchaser or recipient of any or all of the Collateral so disposed of at any public sale (or, to the extent permitted by law, at any private sale), and thereafter hold the same absolutely, free from any claim or right of whatsoever kind, including any right or equity of redemption (statutory or otherwise) of Pledgor, any such demand, notice or right or equity being hereby expressly waived and released. The proceeds of each collection, sale or other disposition under this Section 8.01 shall be applied in accordance with Section 8.04.

8.02 Deficiency. If the proceeds of sale, collection or other realization of or upon the Collateral are insufficient to cover the costs and expenses of such realization, including but not limited to court costs, and the payment in full of the Secured Obligations, Pledgor shall remain liable for any and all deficiency for which Pledgor is obligated under the Loan Documents.

8.03 Private Sale. Neither the Collateral Agent nor any Secured Party shall incur any liability as a result of the sale of the Collateral, or any part thereof, at any private sale conducted in a commercially reasonable manner in accordance with applicable law.

Pledge Agreement

- 7 -

Parties arising by reason of the fact that the price at which the Collateral may have been sold at such private sale was less than the price which might have been obtained at a public sale or was less than the aggregate amount of the Secured Obligations, unless the related sale was not conducted in a commercially reasonable manner in accordance with applicable law.

8.04 Application of Proceeds. Except as otherwise herein expressly provided, the proceeds of any collection, sale or other realization of all or any part of the Collateral, and any other cash at the time held by the Collateral Agent under this Article 8, shall be applied by the Collateral Agent:

First, to the payment of all costs and expenses incurred by the Collateral Agent (in its capacity as such hereunder or as Administrative Agent under any other Loan Document) in connection with such collection or sale or otherwise in connection with this Agreement or any of the Secured Obligations, including all court costs and the fees and expenses of its agents and legal counsel, the repayment of all advances made by the Collateral Agent hereunder or under any other Loan Document on behalf of Pledgor and any other costs or expenses incurred in connection with the exercise of any right or remedy hereunder or under any other Loan Document;

Third, to Pledgor, its successors or assigns, or as a court of competent jurisdiction may otherwise direct.

As used in this Article 8, “proceeds” of Collateral shall mean cash, securities and other property realized with respect to, exchanged for, and distributions in kind of, Collateral, including any thereof received under any merger, reorganization, liquidation or adjustment of debt of Pledgor or any issuer of or obligor on any of the Collateral.

8.06 Notification to Persons Obligated on Collateral. If an Event of Default under the Loan Documents shall have occurred and be continuing, Pledgor shall, at the request of the Collateral Agent, notify persons obligated on any of the Collateral, of the security interest of the Collateral Agent in the Collateral and that payment thereof is to be made directly to the Collateral Agent or its designee, as the Collateral Agent’s agent therefor, and the Collateral Agent may itself, without notice to or demand upon Pledgor, so notify persons obligated on any of the Collateral. After the making of such a request or the giving of any such notification, Pledgor shall hold any proceeds of the Collateral received by Pledgor as trustee for the Collateral Agent without commingling the same with other funds of Pledgor and shall turn the same over to the Collateral Agent in the identical form received, together with any necessary endorsements or assignments. The Collateral Agent shall apply the proceeds of Collateral received by the Collateral Agent to the Secured Obligations in accordance with Section 8.04.

8.07 Standards for Exercising Remedies. To the extent that applicable law imposes duties on the Collateral Agent to exercise remedies in a commercially reasonable manner, Pledgor acknowledges and agrees to the fullest extent permitted by applicable law that it is not commercially unreasonable for the Collateral Agent (a) to fail to incur expenses reasonably deemed significant by the Collateral Agent to prepare Collateral for disposition, (b) to fail to obtain third party consents for access to Collateral to be disposed of, or to obtain or, if not required by other law, to fail to obtain governmental or third party consents for the collection or disposition of Collateral to be collected or disposed of, (c) to fail to exercise collection remedies against account debtors or other persons obligated on Collateral or to remove liens or encumbrances on or any adverse claims against Collateral, (d) to exercise collection remedies against account debtors and other persons obligated on Collateral directly or through the use of collection agencies and other collection specialists, (e) to advertise dispositions of Collateral through publications or media of general circulation, whether or not the Collateral is of a specialized nature, (f) to contact other persons, whether or not in the same business as the Collateral Agent, for expressions of interest in acquiring all or any portion of the Collateral, (g) to hire one or more professional consultants or auctioneers to assist in the disposition of Collateral, whether or not the Collateral is of a specialized nature, (h) to dispose of Collateral by utilizing Internet sites that provide for the auction of assets of the types included in the Collateral or that have the reasonable capability of doing so, or that match buyers and sellers of assets, (i) to dispose of assets in wholesale rather than retail markets, (j) to disclaim disposition warranties, (k) to purchase insurance or credit enhancements to insure the Collateral Agent against risks of loss, collection or disposition of Collateral or to provide to the Collateral Agent a guaranteed return from the collection or disposition of Collateral, or (l) to the extent deemed appropriate by the Collateral Agent, to obtain the services of brokers, investment bankers, consultants and other professionals to assist the Collateral Agent in the collection or disposition of any of the Collateral. Pledgor acknowledges that the purpose of this Section 8.07 is to provide non-exhaustive indications of what actions or omissions by the Collateral Agent would

Pledge Agreement

- 9 -

not be commercially unreasonable in the Collateral Agent’s exercise of remedies against the Collateral and that other actions or omissions by the Collateral Agent shall not be deemed commercially unreasonable solely on account of not being indicated in this Section 8.07. Without limitation upon the foregoing, nothing contained in this Section 8.07 shall be construed to grant any rights to Pledgor or to impose any duties on the Collateral Agent that would not have been granted or imposed by this Agreement or by applicable law in the absence of this Section 8.07.

8.08 Remedies Cumulative. All rights and remedies of the Collateral Agent with respect to the Secured Obligations or the Collateral, whether evidenced by the Loan Documents or by any other instrument or papers, are cumulative, are not exclusive of any other remedies provided by law, and may be exercised singularly, alternatively, successively or concurrently at such time or times as the Collateral Agent deems expedient.

ARTICLE 11. Miscellaneous.

11.01 No Waiver. No failure on the part of the Collateral Agent or any of its agents to exercise, and no course of dealing with respect to, and no delay in exercising, any right, power or remedy hereunder shall operate as a waiver thereof; nor shall any single or partial exercise by the Collateral Agent or any of its agents of any right, power or remedy hereunder preclude any other or further exercise thereof or the exercise of any other right, power or remedy.
