     SECOND AMENDMENT OF LEASE AGREEMENT (the “Second Amendment”) is made and entered into by and between STONEBRIAR I OFFICE PARTNERS, LTD. (“Lessor”), and COMSTOCK RESOURCES, INC. (“Lessee”).

RECITALS:

     WHEREAS, Lessor and Lessee entered into a certain Lease Agreement dated May 6, 2004, (the “Lease”), with the defined terms and conditions of the Lease being hereby incorporated herein by reference; and

     WHEREAS, Lessor and Lessee entered into First Amendment of Lease Agreement dated August 31, 2005; and

     WHEREAS, Lessee desires to exercise the option therein granted it to expand the Premises by incorporating additional space; and

     WHEREAS, Exhibit G of the Lease provides for the manner in which the Lease shall be amended in such circumstances.

     NOW, THEREFORE, for and in consideration of Ten Dollars ($10.00) and other good and valuable consideration paid by each party to the other, the receipt and sufficiency of which is hereby acknowledged, the Lessor and the Lessee hereby amend and modify the Lease, and agree as follows:

     1. Expansion of the Premises. Lessee and Lessor acknowledge that the Premises shall include Suite 320 of the Building, comprising 10,486 additional sqiare feet. Lessor and Lessee further acknowledge that the expiration date of the initial term of the Lease shall continue to be 5:00 p.m., July 31, 2014.

     2. New Rental for the Expanded Premises. Lessor and Lessee agree that the amended monthly Basic Rental payable by Lessee to the Lessor for the Premises shall be the sum of $81,341.25 ($22.50 per square foot) per month, commencing on December 1, 2007 or upon substantial completion of tenant improvements.

     3. Proportionate Shares. Lessee’s Proportionate Share is amended to be 39.75%.

     4. Refinishing. Lessor will provide Lessee with a construction allowance of $9.34 per rentable square foot on the Expanded Premises which includes the cost of new paint and carpet of equal quality to the paint and carpet in Lessee’s existing space.

               Lessor will oversee the construction, act as liaison between Tenant, the contractor, and the designer and coordinate the relationship between the construction, the Building, and the Building systems.
