Mr. Michael German, President

Corning, NY 14830

Dear Mr. German:

This letter sets forth the governing terms of our agreement between Community Bank, N.A. (the "Bank") and Corning Natural Gas Corp. (the "Borrower") concerning a revolving line of credit (the "Revolving Line") in the aggregate maximum amount outstanding at any one time of $7,000,000.00, subject to the terms of this letter. This Revolving Line was committed by the provisions of a commitment letter from the Bank to the Borrower dated February 16, 2011 (the "Commitment Letter"), the contents of which are herein incorporated by reference.

Proceeds of the Revolving Line shall be used for Borrower's working capital purposes needs. So long as no Event of Default exists under this Agreement or under the terms of any other agreement or loan document between the Borrower or any Guarantor hereunder and the Bank, the Borrower may borrow, repay, and reborrow under the Revolving Line from time to time so long as the aggregate principal amount outstanding at any one time does not exceed $7,000,000.00 and the Bank has not demanded payment in full. Notwithstanding the foregoing, beginning March 31, 2010, aggregate borrowings at any one time under the Revolving Line may not exceed the sum then available according to the following formula:

"Eligible accounts receivable" shall be all trade accounts of the Borrower less than 90 days beyond the date of invoice (and originating in the ordinary course of business) minus all contra accounts receivable, affiliate company accounts receivable and employee accounts receivable.

"Miscellaneous eligible inventories" shall be all ordinary-course non-gas inventories of the Borrower valued at cost.

"Rabbi Trust" shall be the investment account of the Borrower numbered 89151111309 held by Community Bank, N.A.

The Borrower shall execute a Demand Grid Note (the "Revolving Line Note") evidencing obligations related to the Revolving Line in a form acceptable to the Bank.

All outstanding amounts under the Revolving Line shall bear interest until paid in full. The rate of interest payable hereunder shall be a fluctuating rate per annum (the "Stated Rate") equal to the greater of 3.50% or the 30-day Libor Rate plus 2.25%, with changes to occur automatically with changes in the 30-day Libor Rate from time to time in effect. Each change in the Stated Rate shall take effect simultaneously with the corresponding change in such Libor Rate. The "30-day Libor Rate" shall mean the 30-day Libor Rate as published by the Wall Street Journal from time to time during the period that any portion of the principal hereunder remains unpaid. Interest shall be calculated based on actual days elapsed divided by a year of 360 days. Changes in the rate of interest applicable to the Revolving Line Note shall become effective automatically and without notice at the time of changes in the 30-day Libor Rate. The Bank, shall, however, provide the Borrower with notice of changes which have occurred in the rate applicable to the Revolving Line during the preceding billing period in its regular billing statements.

Unless sooner demanded, payments of all accrued interest under the Revolving Line are due and payable on the first day of each month. All remaining outstanding principal and accrued interest under the Revolving Line shall be due and payable in full on the earlier of (i) February 28, 2012, or (ii) the date of a demand by the Bank, or (iii) the date of an Event of Default (collectively, the "Expiration Date") unless the Revolving Line is extended by the Bank in its sole discretion. The Revolving Line will terminate on, and the Bank shall have no further obligation to make credit available after, the Expiration Date.

Any amount due not fully paid within ten (10) days after the date due shall be subject to a late payment charge of the greater of $25.00 or five percent (5%) of the total payment due.

The Borrower shall pay any fees, expenses and disbursements, including reasonable legal fees, of the Bank related to the Revolving Line and the transactions contemplated by this letter. Such payments shall be due from time to time upon the Bank giving the Borrower notice of the amount of such expenses.

At the request of the Bank, the Borrower shall promptly pay any expenses, reasonable attorney's fees, costs, or disbursements in connection with collection of any of the obligations related to the Revolving Line or enforcement of any of the Bank's rights hereunder or under any note, guaranty, or other agreement related hereto. This obligation shall survive the payment of the Revolving Line Note. The Bank may apply any payments of any nature received by it first to the payment of obligations under this paragraph, notwithstanding any conflicting provision contained in this letter or any other agreement with the Borrower.

Upon the occurrence of an Event of Default and acceleration by the Bank of the Revolving Line Note such that it becomes immediately due and payable in full, the rate of interest on each of the obligations related thereto shall be increased to a rate at all times equal to two percent (2%) above the rate of interest which would be in effect absent such Event of Default, such increased rate to remain in effect through and including payment in full of all of the Obligations, or written waiver of such Event of Default by the Bank.

• Those financial assets of the Borrower now held by the Bank pursuant to a "Collateral Assignment" dated November 28, 2005;
• A first security interest in accounts receivable, inventory, chattel paper, documents, instruments and general intangibles and equipment arising under a Security Agreement between the Borrower and the Bank dated August 4, 2005 and spread to cover the credit line facility hereby renewed, accomplished by "Collateral Security Spreader Agreement" dated November 28, 2005; and
