A. Roanoke Gas Company and Appalachian Gas entered into an Asset Purchase and Sale Agreement dated as of February 16, 2007 (the “Asset Purchase Agreement”), under which, among other things, Roanoke Gas Company sold to Appalachian Gas, and Appalachian Gas purchased from Roanoke Gas Company the assets from the Bluefield Division of Roanoke Gas Company, on the terms and subject to the conditions set forth therein (the “Acquisition”).

B. In connection with the Acquisition, Appalachian Gas executed in favor of Roanoke Gas Company a Promissory Note in the aggregate amount of One Million Three Hundred Thousand Dollars ($1,300,000) (the “ANGD Note”). All obligations of ANGD to Roanoke Gas Company under the ANGD Note including the obligation to pay principal, interest, fees, premiums and expenses of collection, and including any obligations on account of any extension, renewal or restructuring of the debt due and owing to Roanoke Gas Company by such Borrower under the Subordinated Note, are hereafter referred to as the “Subordinated Debt”. The Subordinated Debt will be secured by all assets of the Borrowers pursuant to the terms of the Asset Purchase Agreement, ANGD Note and all documents related thereto (the “Subordinated Documents”).

C. The Bank and Borrowers are parties to a Loan Agreement dated as of the date hereof, as it may be amended, modified or supplemented from time to time (the “Loan Agreement”), under the terms of which a term loan in the original principal amount of $6,800,000.00 (the “Term Loan”) and a line of credit in the maximum principal amount of $4,400,000.00 (the “Line of Credit”) have been extended by Bank to Borrowers (collectively, the “Bank Loans”). All obligations of Borrowers to the Bank under the Loan Agreement, the other Loan Documents (as defined below) and the Bank Loans, whether such obligations now exist or arise hereafter, including principal, interest, fees, premiums and expenses of collection, and including any obligations on account of any extension, renewal or restructuring of the Bank Loans, is hereafter referred to as the “Senior Debt”. As used herein, the term “Loan Documents” means the documents described in the Loan Agreement as “Loan Documents”, as well as any other agreement, instrument or document executed by any Borrower to evidence any Bank Loan. The Bank Loans will be secured by all assets of Borrowers pursuant to the terms of the Loan Documents.

D. Having determined that the Senior Debt will be of substantial benefit to Borrowers and Roanoke Gas Company, and as required by the Loan Agreement, Roanoke Gas

Company has agreed to the subordination of the Subordinated Debt to the Senior Debt and the lien subordination on the terms and conditions set forth herein.

NOW, THEREFORE, in consideration of the foregoing and other good and valuable consideration, the receipt and sufficiency of which is acknowledged, and intending to be legally bound, the parties agree as follows:

1. All indebtedness, obligations and liabilities of Borrowers under, arising out of, or in any way connected with the Subordinated Debt, or any instruments, agreements or documents relating to the Subordinated Debt, shall be junior in right of payment and collection to the prior payment and collection in full of all Senior Debt. However, Roanoke Gas Company shall not receive scheduled payments on the Subordinated Debt payable to Roanoke Gas Company in the event that an Event of Default has occurred and is continuing under the Loan Documents.

2. Roanoke Gas Company shall not ask, demand or sue for, take or receive, or accelerate or exercise any other remedy or enforcement right (including initiating any suit or proceeding) with respect to, any payment or distribution on account of or for application against any Subordinated Debt from any source, whether as a result of setoff, voluntary payment or otherwise, and Borrowers shall not offer, give or make any payment or distribution on account of or for application to any Subordinated Debt obligations of Borrowers to Roanoke Gas Company, if at the time of such payment or at the time Roanoke Gas Company proposes to take any action described above if any Borrower is in violation of the terms of the Loan Agreement or the other Loan Documents, or if such payment or the taking of such action by Roanoke Gas Company would cause any Borrower to be in violation of the Loan Agreement or the other Loan Documents.

3. In the event of any insolvency, bankruptcy, liquidation or assignment for the benefit of creditors of any Borrower, or in the event of any acceleration of the Subordinated Debt, the Senior Debt shall be accelerated as provided in the Loan Documents and all of the Senior Debt shall be paid in full before any payment or distribution shall be made on account of or for application against any Subordinated Debt.

4. Subject to the terms and conditions of this Agreement, Roanoke Gas Company hereby agrees that all security interests and liens of Roanoke Gas Company securing the Subordinated Debt, whether now existing or hereafter created or acquired, in assets of any Borrower that constitute collateral securing the Bank Debt (the “Collateral”) shall be subordinate and junior in lien, right, priority and dignity to any lien or security interest of Bank in the Collateral securing the Senior Debt, regardless of (i) the date, manner, order or method of attachment or perfection of any such security interests or liens, (ii) the time or order of filing or recording of financing statements or other agreements, documents or instruments filed or recorded to perfect security interests or liens in any Collateral or any failure of Bank to file or record any financing statement or any continuations thereof under the Uniform Commercial Code or other law in any other applicable jurisdiction to perfect security interests or liens in any Collateral, (iii) anything contained in any filing or agreement to which Bank or Roanoke Gas
