BY AND BETWEEN

CORNING NATURAL GAS CORPORATION

AND

TALISMAN ENERGY USA INC.

THIS AGREEMENT, dated May 13, 2010 between Corning Natural Gas Corporation ("CNGC" and a "Party" hereto), a New York Corporation, and Talisman Energy USA Inc. ("Talisman" and a "Party" hereto), a Delaware Corporation, modifies amends and supersedes the "negotiated 311 transportation service agreement by and between Corning Natural Gas Corporation and Fortuna Energy Inc." dated January 11, 2010 and any other agreement or understanding, oral or written, between the parties. This agreement is for natural gas transportation service to be provided to Talisman by CNGC on the CNGC natural gas system.

WHEREAS, the Parties desire to enter into a transportation agreement. In order to accomplish this goal, the Parties contemplate that Talisman will deliver natural gas to be transported hereunder and that CNGC will provide transportation service for such natural gas supplies from the Receipt Point to the Delivery Point (as said terms hereafter are defined); and

WHEREAS, Talisman or its agent/supplier has made or will have made arrangements for transportation of said supply of natural gas to said facilities of CNGC:

NOW, THEREFORE, in consideration of the mutual promises made herein and other good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, the Parties agree as follows:

1. DEFINITIONS

The following capitalized terms are used in this Agreement as defined below.

"Access Agreement" refers to a contract between CNGC and Fortuna Energy Inc. (a predecessor corporation to Talisman) dated April 1, 2006, that specifies the obligation of both parties with respect to Talisman having access to the CNGC transmission and distribution system.

"Commencement Date" shall mean the date that CNGC notifies Talisman that CNGC stands ready to transport gas from the Receipt Point to the Delivery Point(s) pursuant to this Agreement.
