                                ----------------

         This Waiver Agreement (this "Agreement") dated as of December 5, 2005,
is made between GMX Resources Inc., an Oklahoma corporation ("Borrower"), and
Hibernia National Bank, a national banking association ("Lender") who agrees as
follows:

         A. This Agreement pertains to that certain Loan Agreement (Line of
Credit) dated as of July 29, 2005, between Borrower and Lender (the "Loan
Agreement"). As used in this Agreement, capitalized terms used herein without
definition herein shall have the meanings provided in the Loan Agreement.

         1. Borrower has advised Lender that Borrower desires to establish a new
Subsidiary as an Oklahoma corporation (and qualified to do business in Texas),
with 100% of the capital stock owned by the Borrower. This new Subsidiary will
acquire and operate one or more drilling rigs. The Borrower will provide working
capital to the new Subsidiary, a portion of which will be funded from the Loan.
The new Subsidiary's acquisition of its first rig will be by purchase from
McLachlan Drilling Company for an aggregate purchase price of approximately
$5,100,000.00. This price is to be paid on or about January 2, 2006, and for the
1 month interim period Borrower on behalf of the new Subsidiary shall incur
indebtedness owing to McLachlan Drilling Company, secured by a security interest
Lien on the drilling rig being acquired. At Borrower's request, and subject to
the terms of this Agreement, Lender hereby grants a one-time waiver or consent
as to each of (i) the covenant in Section 6.3 requiring the Lender's prior
written consent for the Borrower to establish a new Subsidiary, to permit the
establishment of this Subsidiary, (ii) the covenant in Section 6.1 limiting
Debt, to permit the purchase money Debt owing to McLachlan Drilling Company, and
(iii) the covenant in Section 6.2 prohibiting Liens, to permit the purchase
money Lien in favor of McLachlan Drilling Company.

         2. Borrower and Lender agree to execute and deliver promptly a First
Amendment to Loan Agreement, which shall include without limitation agreements
by Borrower (a) to pledge the stock of the new Subsidiary to the Lender pursuant
to the terms of a security agreement in substantially the same form as the
Security Agreement (Stock) pledging the stock of Endeavor, (b) to cause all loan
advances made by the Borrower to the new Subsidiary to be evidenced by a
negotiable promissory note which (i) is payable to the order of the Borrower,
(ii) waives the Subsidiary's right to set off, (iii) is secured by a security
interest in the drilling rigs, and (iv) is (together with such security
agreement) otherwise in form and substance reasonably satisfactory to the
Lender, (c) to pledge such intercompany note to Lender and to cause the
Subsidiary to execute and deliver to Lender an acknowledgment of the pledge of
the intercompany note by the Borrower to the Lender as further security for the
Indebtedness, all in form and substance satisfactory to the Lender, and (d) to
establish a maximum limit on the amount of the Borrower's investment (both debt
and equity) in the new Subsidiary under Section 6.3 at $12 million. In
connection with the foregoing, the Borrower shall execute and deliver or cause
the new Subsidiary to execute and deliver such further documents, agreements and
instruments in compliance with or accomplish of the foregoing, including without
limitation the note by the new Subsidiary to the Borrower, the security
agreement by the new Subsidiary to the Borrower, the security agreement by the
Borrower to the Lender pledging the promissory note, an acknowledgment of pledge
by the new Subsidiary in favor of the Lender, a stock pledge agreement by the
Borrower, the originals of intercompany promissory note and stock certificate,

         3. The First Amendment to Loan Agreement shall be executed by the
parties no later than December 20, 2005, together with the stock pledge
agreement by Borrower and delivery of the stock certificate. The Debt owing by
the Borrower to McLachlan Drilling Company for the purchase of the drilling rig
shall not exceed $5,200,000.00 and, and the Lien granted to McLachlan Drilling
Company shall encumber only the drilling rig being purchased and no other
assets. The Debt owing to McLachlan Drilling Company shall be paid in full, and
the Lien held by McLachlan Drilling Company shall be released of record, no
later than January 18, 2006. The Collateral Documents pledging the promissory
note issued by Subsidiary to Borrower (and related documents as provided herein)
shall be executed and delivered to Lender no later than January 25, 2005.

         4. Except as expressly modified by this Agreement, all terms and
provisions of the Loan Agreement are hereby ratified and confirmed and shall be
and shall remain in full force and effect, enforceable in accordance with their
terms.

         5. Borrower hereby represents and warrants that no Default has occurred
and is continuing on the date hereof, and further represents and warrants that
all of the representations, warranties and covenants made in the Loan Agreement
are, as of the date hereof, true and correct in all material respects.

         6. Borrower hereby represents and warrants that there is no defense,

amounts due under, or performance of, the terms of the Note and the Loan
Agreement, and to the extent any such defense, offset, compensation,
