FOURTH AMENDED AND RESTATED LINE OF CREDIT AGREEMENT

THIS FOURTH AMENDED AND RESTATED LINE OF CREDIT AGREEMENT (this “Agreement”) is made and entered into as of May 29, 2006, by and between CoBANK, ACB (“CoBank”) and COMMONWEALTH TELEPHONE COMPANY (the “Borrower”).

WHEREAS, the Borrower and CoBank have previously entered into that certain Third Amended and Restated Line of Credit Agreement, dated as of May 31, 2005 (the “Prior Agreement”); and

WHEREAS, CoBank and the Borrower desire to amend and restate in its entirety the Prior Agreement; and

WHEREAS, this Agreement, among other things, will extend the availability period for Loans hereunder and increase the available loan amount as more fully provided herein.

SECTION 1. The Loan. On the terms and conditions set forth in this Agreement, and subject to Section 11, CoBank agrees to make advances to the Borrower during the period commencing on May 29, 2006 and ending at 12:00 noon Eastern time on May 27, 2007 (the “Availability Period”) in an aggregate principal amount up to $135,000,000 at any one time outstanding (the “Loan”). Within the limits of the Loan, the Borrower may borrow, repay and reborrow.

SECTION 2. Purpose and Use of Proceeds. The proceeds of the Loan shall be applied by the Borrower to refinance existing indebtedness of the Borrower and to finance capital expenditures, working capital and other general corporate purposes of the Borrower. The Borrower agrees that the proceeds of the Loan shall be used for only the purpose set forth in this Section 2.

SECTION 3. Availability. Subject to Section 11, the advances under the Loan will be made on any day on which CoBank is open for business (a “Business Day”), except any day when Federal Reserve Banks are closed, by wire transfer of immediately available funds to such account or accounts as the Borrower may designate, provided that (i) an authorized officer of the Borrower shall have provided CoBank with at least one Business Day’s prior written notice of the date on which such advance under the Loan is to be made (each, a “Funding Date”), unless the Borrower elects to have a portion of the Loan accrue interest at a LIBOR Rate (as defined in Section 4(A)(2)), in which case the Borrower shall have provided such notice two Banking Days (as defined in Section 4(A)(2)) prior to such Funding Date and such Funding Date shall be a Banking Day, and (ii) any Funding Date so designated shall not be later than the last day of the Availability Period. A “Banking Day” means a Business Day on which dealings in U.S. dollar deposits are carried out in the London Interbank Market and banks are open for business in New York, New York and London, England.

SECTION 4. Interest and Fees.

(A) The unpaid principal balance of the Loan shall accrue interest at the rate or rates selected by the Borrower in accordance with this Subsection (A).

(1) Base Rate Option. As to any portion of the unpaid principal balance of the Loan selected by the Borrower (any such portion, and any portion selected pursuant to Subsection (A)(2), is hereinafter referred to as a “Portion” of the Loan), interest shall accrue pursuant to this variable rate option at a variable annual interest rate equal to the sum of the Base Rate (as hereinafter defined) minus 1.00%. “Base Rate” means a variable rate of interest per annum equal, on any day, to the higher of (i) CoBank’s Base Rate or (ii) the sum of Federal Funds Rate plus 0.50%. “Federal Funds Rate” shall mean, for any day, the rate of interest per annum (rounded upward, if necessary, to the nearest whole multiple of 1/1000 of 1%) equal to the weighted average of the rates on overnight Federal funds transactions with members of the Federal Reserve System arranged by Federal funds brokers, as published by the Federal Reserve Bank of New York on the Business Day next succeeding such day, provided that (i) if such day is not a Business Day, the Federal Funds Rate for such day shall be such rate on such transactions on the next preceding Business Day and (ii) if no such rate is so published on the next succeeding Business Day, the Federal Funds Rate for such day shall be the average rate quoted to CoBank on such day on such transactions as determined by CoBank. The term “Base Rate” shall mean the rate of interest established by CoBank from time to time as its Base Rate, which rate is intended by CoBank to be a reference rate and not its lowest rate, and CoBank may charge other borrowers rates at, above, or below that rate. The Base Rate will change on the date established by CoBank as the effective date of any change thereof.

(2) LIBOR Option. As to any Portion or Portions of the Loan selected by the Borrower, interest shall accrue pursuant to this LIBOR option at a fixed annual interest rate (a “LIBOR Rate”) equal to the sum of LIBOR (as hereinafter defined) plus 0.625%. Under this option: (i) rates may be fixed for Interest Periods (as hereinafter defined) of one, two, three, or six months, as selected by the Borrower; (ii) amounts fixed shall be in increments of $100,000 or multiples thereof; and (iii) rates may only be fixed on a Banking Day on three Banking Days’ prior written notice; provided, however, that the LIBOR option shall not be available with respect to new advances during the continuance of any Default or Event of Default. “LIBOR” means the rate (rounded upward to the nearest sixteenth of one percent and adjusted for reserves required on Eurocurrency Liabilities (as hereinafter defined) for banks subject to FRB Regulation D (as hereinafter defined) or required by any other federal law or regulation) quoted by the British Bankers Association (the “BBA”) at 11:00 a.m. London time two Banking Days before the commencement of the Interest Period for the offering of U.S. dollar deposits in the London interbank market for the Interest Period designated by the Borrower, as published by Bloomberg or another major information vendor listed on BBA’s official website. “Banking Day” shall mean a day on which CoBank is open for business, dealings in U.S. dollar deposits are being carried out in the London interbank market, and

2

Loan No. S0667F

banks are open for business in New York City and London, England. “Interest Period” shall mean the time period chosen by the Borrower during which the chosen fixed rate is to apply to a Portion of the Loan, which period commences on the day a rate fixed under this Subsection 4(A)(2) becomes effective. The Interest Period for Portions accruing interest at the LIBOR option rate shall end on the day in the next calendar month or in the month that is one, two, three, or six months thereafter which corresponds numerically with the day the Interest Period commences; provided, however, that: (a) in the event such ending day is not a Banking Day, such period shall be extended to the next Banking Day unless such next Banking Day falls in the next calendar month, in which case it shall end on the preceding Banking Day; and (b) if there is no numerically corresponding day in the month, then such period shall end on the last Banking Day in the relevant month. No Interest Period shall extend beyond the Maturity Date (as defined in Section 5). “Eurocurrency Liabilities” has the meaning as set forth in FRB Regulation D. “FRB Regulation D” means Regulation D as promulgated by the Board of Governors of the Federal Reserve System, 12 CFR Part 204, as amended from time to time.

(3) Selection And Changes of Rates. The Borrower shall select the applicable interest rate option or options at the time it gives CoBank written notice of the Funding Date for an advance pursuant to Section 3. The Borrower may, on any Banking Day, elect to have the LIBOR Rate apply to any Portion of the Loan then accruing interest at the Base Rate. In addition, with respect to any Portion of the Loan accruing interest pursuant to the LIBOR Rate, the Borrower may, subject to Subsection (A)(2), two Banking Days prior to the last day of the Interest Period for such Portion, elect to fix the interest rate accruing on such Portion for an Interest Period at a LIBOR Rate. In the absence of any such refix, interest shall automatically accrue on such Portion of the Loan at the Base Rate minus 1% as provided in Section 4(A)(1). Notwithstanding the foregoing, in the event the Borrower elects to have any Portion of the Loan accruing interest at the LIBOR Rate and the last day of the Interest Period for such Portion is not a Banking Day, then interest shall accrue on such Portion at the Base Rate minus 1% as provided in Section 4(A)(1) until the LIBOR Rate becomes effective. From time to time the Borrower may elect on a Business Day and upon payment of the Surcharge (as defined in, and calculated pursuant to, Section 6), to convert all, but not part, of any Portion of the Loan accruing interest pursuant to the LIBOR Rate to accrue interest at the Base Rate or pursuant to the LIBOR Rate for another Interest Period selected in accordance with Subsection (A)(2); provided, however, that any such conversion to a LIBOR Rate shall not be effective until two Banking Days after such election, which can only be made on a Banking Day. Except for the initial selection, all interest rate selections provided for herein shall be made by telephonic or written request of an authorized employee of the Borrower by 12:00 noon, Eastern time, on the relevant day. In taking actions upon telephonic requests, CoBank is entitled to rely on (and will incur no liability to the Borrower in acting upon) any request made by a person identifying himself or herself as one of the persons authorized by the Borrower to select interest rates hereunder; provided, however, that in the case of LIBOR rate loans, all such selections must be confirmed in writing upon CoBank’s request.

Loan No. S0667F

(4) Accrual of Interest. Interest shall accrue pursuant to any LIBOR Rate selected by the Borrower from and including the first day of the applicable Interest Period to but excluding the last day of the Interest Period. If the Borrower elects to refix the interest rate on any Portion of the Loan pursuant to Subsection (A)(3), the first day of the new Interest Period shall be the last day of the preceding Interest Period. In the absence of any such refix, interest shall accrue on such Portion at the Base Rate minus 1% as provided in Section 4(A)(1) from and including the last day of such Interest Period. If the Borrower elects to convert from the LIBOR Rate to the Base Rate or to the LIBOR Rate upon payment of the Surcharge as provided in Subsection (A)(3), interest at the existing LIBOR Rate shall accrue through the day before such conversion and either (i) the first day of any new Interest Period shall be the date of such conversion, or (ii) interest at the Base Rate shall accrue on the Portion of the Loan so converted from and including the date of conversion.

(5) Rate Combinations. Notwithstanding the foregoing, at any one time there may be no more than five Portions of the Loan in the aggregate accruing interest pursuant to the LIBOR option.

(B) Payment and Calculation. The Borrower will pay interest on the Loan (i) monthly in arrears on the 20th day of the following month (or on such other day in such month as CoBank will require in a written notice to the Borrower); provided, however, in the event the Borrower elects to fix all or a portion of the indebtedness outstanding under the LIBOR interest rate option above, at CoBank’s option upon written notice to the Borrower, interest will be payable at the maturity of the Interest Period and if the LIBOR interest rate fix is for a period longer than 3 months, interest on that Portion will be payable quarterly in arrears on each three-month anniversary of the commencement date of such Interest Period, and at maturity of such Interest Period, (ii) upon any prepayment (whether due to acceleration or otherwise) and (iii) on the Maturity Date; provided, further, however, that if any such payment date for accrued interest is not a Business Day, then the accrued interest then due shall be paid on the next Business Day. Interest will be calculated on the actual number of days the Loan, or any part thereof, is outstanding on the basis of a year consisting of 360 days. In calculating accrued interest, the date the Loan is made will be included and the date any principal amount of the Loan is repaid or prepaid will be excluded as to such amount.

(C) Default Rate. After maturity, whether by reason of acceleration or otherwise, or upon the occurrence and during the continuation of an Event of Default, including if the Borrower fails to make any payment or investment required to be made under the terms of this Agreement or the Note (including this Section 4), then, at CoBank’s option in each instance, the unpaid principal balance of the Loan shall accrue interest at 2% per annum in excess of the Base Rate. All interest provided for in this Subsection (C) shall be payable on demand and shall be calculated from and including the date such payment was due to but excluding the date paid on the basis of a year consisting of 360 days.

(D) Commitment Fee. In consideration of the Loan, the Borrower shall pay a commitment fee on the average daily unused Portion of the Loan at the rate of 0.125% per annum

4

Fourth Amended and Restated Line of Credit Agreement/Commonwealth

Loan No. S0667F

(calculated on a 360-day basis), payable monthly in arrears by the twentieth (20th) day of the following month (or such other day of such month as CoBank may require in written notice to the Borrower). Such fee shall be payable for each month (or portion thereof) occurring during the original or any extended term of the Loan.

SECTION 5. Principal Repayment and Maturity. The term of the Loan shall be from May 29, 2006 to May [27], 2007 (the “Maturity Date”). On the Maturity Date, the amount of the then unpaid principal balance of the Loan and any and all other amounts due and owing hereunder or under any other Loan Document shall be due and payable. If the Maturity Date is not a Business Day, then the principal installment then due shall be paid on the next Business Day and shall continue to accrue interest until paid. The Borrower shall have the right, upon at least three Business Days’ prior written notice to CoBank, to permanently reduce or terminate the Loan, provided, however, no reduction or termination shall be permitted if, after giving effect thereto and to any prepayment made therewith, the aggregate principal balance of the Loan then outstanding would exceed the Loan as so reduced.

SECTION 6. Prepayment. The Borrower may, on (i) one Business Day’s prior written notice, prepay in full or in part, any Portion of the Loan accruing interest at the Base Rate, or (ii) on two Business Day’s prior written notice, prepay in full or in part, in minimum amounts of $100,000, any Portion of the Loan accruing interest at the LIBOR Rate. Notwithstanding the foregoing, the Borrower’s right to prepay any Portion of the Loan accruing interest at the LIBOR Rate shall be conditioned upon the payment of a surcharge (the “Surcharge”) equal to the present value of any funding losses incurred by CoBank as a result of such prepayment. The Surcharge, including the amount of any funding losses, shall be the greater of $300 or the amount determined and calculated as follows:

(A) Determine the difference between: (i) CoBank’s cost of funds (determined in accordance with its standard methodology) on the date the interest rate was fixed to fund the Portion of the Loan being prepaid; minus (ii) CoBank’s cost of funds (determined in accordance with such methodology) on the date of prepayment to fund a new loan with a weighted average life equal to the weighted average life over the remainder of the selected Interest Period of the Portion of the Loan being prepaid. If such difference is negative, then no Surcharge other than $300 is payable.

(B) If such difference is positive, divide the result determined in Subsection (A) by 12.

(C) For each month or part thereof during which the Portion of the Loan prepaid was scheduled to have been outstanding, multiply the amount determined in Subsection (B) by that part of the Portion of the Loan prepaid that was scheduled to have been outstanding during such month (such that there is a monthly calculation for each month during which the Portion of the Loan prepaid was scheduled to have been outstanding).

5

Fourth Amended and Restated Line of Credit Agreement/Commonwealth

Loan No. S0667F

(D) Determine the present value of each monthly calculation made under Subsection (C) based upon the scheduled time that interest on the Portion of the Loan prepaid would have been payable and a discount rate equal to the rate set forth in Subsection (A)(ii).

(E) Add all of the calculations made under Subsection (D). The result shall be the Surcharge.

For purposes of calculating the Surcharge provided for in this Section 6, early conversion of a Portion of the Loan accruing interest pursuant to the LIBOR rate so that it accrues interest at a different rate pursuant to Section 4(A)(3) shall be deemed a prepayment in full of that Portion of the Loan.

SECTION 7. Note. The Borrower’s obligation to repay the Loan shall be evidenced by an amended and restated promissory note, dated as of even date herewith, in form and content acceptable to CoBank (as the same may be amended, modified, supplemented, extended or restated from time to time and any promissory note that may be issued from time to time in substitution, renewal, replacement or exchange therefor, the “Note”).

SECTION 8. Manner and Time of Payment. If any date on which payment is due hereunder is not a Business Day, the payment shall be made on the next succeeding Business Day. The Borrower shall make each payment under this Agreement and under the Note by wire transfer of immediately available funds or by check. Wire transfers shall be made to ABA No. 307088754 for advice to and credit of “CoBANK” (or to such other account as CoBank may designate by notice) with sufficient information to identify the source and application of such funds. The Borrower shall give CoBank telephonic notice no later than 12:00 noon, Eastern time, of its intent to pay by wire transfer. Wire transfers received after 3:00 p.m., Eastern time, shall be credited on the next Business Day. Checks shall be mailed or delivered to CoBank at Department 167, Denver, Colorado 80291-0167 (or to such other address as CoBank may designate by notice). Credit for payment by check will not be given until the next Business Day after receipt of the check or the actual receipt of immediately available funds, whichever is later.

SECTION 9. Capitalization. The Borrower agrees to purchase non-voting participation certificates in CoBank as CoBank may from time to time require in accordance with its bylaws and capital plan (as each may be amended from time to time), except that the maximum amount of non-voting participation certificates that the Borrower may be required to purchase in connection with a loan may not exceed the maximum amount permitted by the bylaws at the time the Agreement relating to such loan is entered into or such loan is renewed or refinanced by CoBank. In connection with the foregoing, the Borrower hereby acknowledges receipt, prior to the execution of this Agreement, of CoBank’s bylaws, a written description of the terms and conditions under which the equity is issued, CoBank’s Loan-Based Capital Plan, CoBank’s most recent annual report, and if more recent than CoBank’s latest annual report, its latest quarterly report. All such investments and all other equities which the Borrower may now own or hereafter acquire or be allocated in CoBank shall be subject to a statutory first lien in favor of CoBank.

(E) Compliance with Laws. The Borrower is in compliance in all material respects with all federal, state, and local laws, rules, regulations, ordinances, codes, and orders (collectively, “Laws”), the failure to comply with which could have a material adverse effect on the condition, financial or otherwise, operations, properties, or business of the Borrower, or on the ability of the Borrower to perform its obligations under the Loan Documents, except as the Borrower has disclosed on Schedule 1 hereto.
