hereto in separate counterparts, each of which when so executed
shall be deemed to be an original and all of which taken together shall constitute one and the same agreement. Delivery of an executed counterpart of a signature page to this Amendment No. 1 by

7. Governing Law. This Amendment No. 1 and the rights and obligations of the parties hereunder shall be governed by, and
construed and interpreted in accordance with, the laws of the State of New York.

CONSENTEXHIBIT 10.1
                                                                    ------------

                             PARTICIPATION AGREEMENT

         This Participation Agreement (this "Agreement"), executed the date as
of each signature hereinbelow, but dated effective as of December 5, 2003
("EFFECTIVE DATE"), by and between PENN VIRGINIA OIL & GAS CORPORATION, with
offices at 840 Gessner, Suite 800, Houston, Texas 77024 ("PVOG") and GMX
RESOURCES INC. and its wholly-owned subsidiaries, EXPEDITION NATURAL RESOURCES
INC. and ENDEAVOR PIPELINE, INC., with offices at One Benham Place, Suite 600,
9400 N. Broadway, Oklahoma City, Oklahoma, 73114 (collectively, "GMX"). PVOG and
GMX are sometimes referred to herein collectively as the "Parties" and each
individually as a "Party".

                                   RECITATION
                                   ----------

         GMX is the leasehold owner of 100% of the working interest comprising
17,816 gross and 15,374 net acres in Harrison and Panola Counties, Texas
hereinafter referred to as the "BLOCKER PROSPECT". For purposes of addressing
the rights and obligations of the Parties herein, the Blocker Prospect is
divided into three geographic Phases. "PHASE I", "PHASE II" AND "PHASE III" each
are located on the plat identified in Exhibit "A-2" with the applicable leases
for Phases I and II being identified in Exhibits "A-3" and "A-4". Such exhibits
are further referenced as follows:

         Exhibit "A-1"     Identification of Properties for each Phase
         Exhibit "A-2"     Plat of the Leases and AMI
         Exhibit "A-3"     Description of Leases for Phase I
         Exhibit "A-4"     Description of Leases for Phase II

         The Parties desire to enter into this Agreement to provide for the
exploration and development of the Blocker Prospect subject to the terms and
conditions set forth herein.

         NOW THEREFORE, for and in consideration of the mutual covenants,
promises, rights and obligations contained herein and for other good and
valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, the Parties agree as follows:

                                    SECTION I

                           GMX DRILLING LOCATION PADS
                           --------------------------

         1.1 DRILLING LOCATION PADS.
             -----------------------

PVOG will prepay GMX $250,000 to be used as a reimbursement for future drilling
location pads previously built by GMX. Such location pads and GMX's actual costs
are identified on Exhibit "B" attached hereto. PVOG agrees that if there are any
drilling locations PVOG identifies within 467 feet of a GMX location pad, then
PVOG will utilize such GMX location pad and reimburse GMX for the actual
location and title costs incurred for the applicable location in accordance with
Exhibit "B"; provided, however, if the objective depth for any well is 7,000
feet or less, the reimbursement obligation shall be limited to $40,000 plus a
mutually agreed amount for any GMX's costs in excess of pad construction costs.
The $250,000 reimbursement for future drilling location pads shall be paid no
later than January 7, 2004. At such time such location pads may be used, the
costs will be joint billed to the participating Parties pursuant to the
respective AFE. To the extent GMX is obligated to pay costs for drilling on any
such location, it will pay its share of such costs. Otherwise, the $250,000
payment to GMX will be nonrefundable.

                                   SECTION II

                                   OPERATIONS
                                   ----------

         2.1 OPERATIONS.
             -----------

PVOG will be designated as Operator on all new drilling, completion and
production activities affecting Phase I and Phase II while this Agreement is in
effect. The Blocker Prospect will be subject to either "OPERATING
AGREEMENT-UNIT" as attached in Exhibit "C-1" or "OPERATING AGREEMENT-WELLBORE"
as attached as Exhibit "C-2". The respective Operating Agreement-Unit or
Operating Agreement-Wellbore shall be applicable as identified in the Sections
hereinbelow. No more than one well in which GMX has elected to participate may
be drilled or drilling at the same time for wells in Phase I, Part B and Phase
II, Part B collectively. If either Party elects not to participate in a well in
Phase I, Part B or Phase II, Part B, the non-consenting Party shall farmout its
interest to the consenting Party in the applicable wellbore with a 77% NRI,
proportionately reduced to its interest, and retaining an overriding royalty for
any NRI in excess of such amount.

                                   SECTION III

            BLOCKER PROSPECT PHASES (PHASE I, PHASE II AND PHASE III)
            ---------------------------------------------------------

         3.1 PHASE I.
             --------

                           3.1.1    PHASE I,  PART A.

                              3.1.1.1 ACQUISITION OF OIL & GAS LEASES.

                                    3.1.1.1.1 LEASE COSTS REIMBURSEMENT. Upon
                                    execution of this Agreement, PVOG shall pay
                                    GMX an upfront land reimbursement cost of
                                    $700,932 ($200/acre for 4,289 net acres for
                                    an 80% working interest) in exchange for an
                                    assignment of 80% of GMX's leasehold working
                                    interest in all of GMX's leases within Phase
                                    I. The net revenue interest ("NRI")
                                    delivered to PVOG will be GMX's recorded
                                    lease NRI. The assignment shall be in the
                                    form of Exhibit D, which shall include an
                                    exclusion for existing wellbores, equipment
                                    and certain other rights which will be
                                    retained by GMX.

                                    3.1.1.1.2 TITLE TO LEASES. GMX represents
                                    and warrants that the interest being
                                    delivered to PVOG is free of any burdens,
                                    liens or encumbrances created by, through
                                    and under GMX but not otherwise. In order
                                    that the Parties may close this Agreement on
                                    or before December 31, 2003 and given the
                                    insufficient time for PVOG to verify title
                                    to the Phase I leases, GMX agrees that if
                                    title should fail to any of the GMX leases
                                    within Phase I, provided such failure is
                                    identified within one (1) year, then GMX
                                    shall promptly reimburse PVOG $200 per net
                                    mineral acre, proportionally reduced to
                                    PVOG's working interest.

                                    3.1.1.1.3 LEASE MAINTENANCE. GMX agrees to
                                    properly and timely pay, or cause to be
                                    paid, all delay rentals and shut-in payments
                                    (collectively the "Lease Maintenance Costs")
                                    which are required to be paid to maintain in
                                    force and effect as to the existing GMX
                                    leases identified in Exhibit "A-3" until
                                    such time as PVOG has the opportunity to

                                  Page 2 of 11
<PAGE>

                                    input such leases within PVOG's system. PVOG
                                    will notify GMX in writing when it is
                                    prepared to take over such lease maintenance
                                    responsibilities.

                              3.1.1.2  DRILLING OPERATIONS OF PHASE I, PART A.

                                    3.1.1.2.1 DRILLING PROGRAM. Upon the
                                    execution of this Agreement, PVOG will have
                                    the right to select locations with the
                                    option to drill five (5) wells to the Cotton
                                    Valley Formation within the current GMX
                                    designated acreage position or Phase I AMI.
                                    PVOG will pay 100% of the costs of the
                                    completed well to the tanks or sales line as
                                    the case may be, excluding any acreage costs
                                    to acquire additional acreage in any unit in
                                    which a well is drilled for which GMX will
                                    bear its 20% proportionate share of costs.
                                    As of first sales from each well drilled
                                    under this paragraph, PVOG will have an 80%
                                    working interest and GMX will have a 20%
                                    working interest in all future costs and
                                    elections pursuant to Operating
                                    Agreement-Unit attributable to such well and
                                    applicable unit.

                                    3.1.1.2.2 CONTINUOUS DRILLING. It is PVOG's
                                    intent to drill five (5) wells on a
                                    back-to-back basis. If (i) PVOG does not
                                    drill 5 wells; (ii) the first well is not
                                    commenced prior to March 1, 2004 or (iii) if
                                    there is a delay of more than sixty (60)
                                    days between the completion of one well and
                                    the commencement of operations on the next
                                    well under this paragraph, this Agreement
                                    shall terminate, PVOG shall have no further
                                    rights hereunder. PVOG will have the right
                                    to bank any unused continuous drilling or
                                    operation days between wells to be credited
                                    for future wells if it elects to do so.

                                    3.1.1.2.3 SUBSTITUTE WELL. PVOG shall
                                    commence the drilling of wells as provided
                                    herein and continue the operation with due
                                    diligence (i) to the objective depth, or
                                    (ii) until it encounters mechanical
                                    difficulties, uncontrolled influx of
                                    subsurface water, abnormal pressures,
                                    pressured or heaving shale, salt, granite or
                                    other practicably impenetrable substances or
                                    other similar conditions prevail in the hole
                                    that render further drilling impracticable.
                                    If such well is abandoned due to the
                                    conditions described above, then PVOG may
                                    drill a substitute well.

                                          extent it arises from leases relating
                                          to the 80% interest assigned by GMX to
                                          PVOG. In the event PVOG elects to
                                          participate in the 1st well in Phase
                                          I, Part B and PVOG has not spent at

                                            PART A.

                                          3.2.1.1.1 DRILLING PROGRAM. Phase II,
                                          Part A may commence after completion
                                          of Phase I, Part A. If proposed by
                                          PVOG, the first Phase II well may spud
                                          no earlier than January 1, 2005 and no
                                          later than July 1, 2005. In Phase II,
                                          Part A, PVOG will select locations
                                          with the option to drill four (4)
                                          wells to the Cotton Valley Formation
                                          within the current GMX designated
                                          acreage position or Phase II AMI. Such
                                          drilling will be governed by an
                                          Operating Agreement- Unit for each
                                          unit in which a well is drilled. In
                                          the event PVOG selects an existing GMX
                                          location, as identified in Exhibit
                                          "B", PVOG will reimburse GMX for
                                          actual location and title costs
                                          incurred for the applicable location
                                          in accordance with Exhibit B. PVOG
                                          will pay 100% of the costs of the
                                          completed well to the tanks or sales
                                          line as the case may be, excluding any
                                          additional acreage costs for acreage
                                          in the unit in which the well is
                                          drilled. As of first sales from each
                                          well drilled under this paragraph,
                                          PVOG will earn an assignment of (i)
                                          80% of the GMX working interest and
                                          GMX will have a 20% working interest
                                          in all future costs and elections
                                          relating to such well; and (ii) 50% of
                                          the GMX working interest in the unit
                                          (excluding the wellbore of such well)
                                          and GMX will have the remaining 50% as
                                          it relates to all future operations
                                          and elections in such unit, pursuant
                                          to the Operating Agreement-Unit
                                          attributable to such well and
                                          applicable unit. GMX will retain a
                                          100% working interest, including any
                                          liability for operations or
                                          abandonment in their existing
                                          wellbores and equipment as to the HBP
                                          acreage included in Phase II. The
                                          assignment shall be free of any
                                          burdens, liens or other encumbrances
                                          created by, through or under GMX but

                                          3.2.1.1.2 CONTINUOUS DRILLING. It is
                                          PVOG's intent to drill four (4) wells
                                          on a back-to-back basis in Phase II,
                                          Part A. If (i) the first well is not
                                          commenced before July 1, 2005; (ii)
                                          four wells are not drilled or (iii)
                                          there is a delay of more than sixty

                                          operations on the next well under this
                                          paragraph, PVOG will forfeit its
                                          rights under this Agreement as it
                                          relates to Phase II, Part B and Phase
                                          III, retaining only the interest that
                                          has been earned as of the date of the
                                          forfeiture. PVOG will have the right
                                          to bank any unused continuous drilling
                                          or operation days between wells to be
                                          credited for future wells if it elects
                                          to do so. PVOG will incur no other
                                          penalties or liabilities other than as
                                          provided above.

                                          3.2.1.1.3 SUBSTITUTE WELL. PVOG shall
                                          commence the drilling of wells as
                                          provided herein and continue the
                                          operation with due diligence (i) to
                                          the objective depth, or (ii) until it
                                          encounters mechanical difficulties,
                                          uncontrolled influx of subsurface

                                          prevail in the hole that render
                                          further drilling impracticable. If
                                          such well is abandoned due to the
                                          conditions described above, then PVOG
                                          may drill a substitute well

                                          At such time the interest is delivered
                                          to PVOG, pursuant to the terms herein,
                                          such interest shall be free of any
                                          liens, burdens, or other encumbrances
                                          created by, through or under GMX but
                                          not otherwise..

                                          maintain and be responsible for all
                                          GMX leases within Phase II. GMX will
                                          use its best efforts to properly and
                                          timely pay all Lease Maintenance Costs
                                          which are required to be paid to

                                          existing GMX leases identified in
                                          Exhibit "A-4" until such time PVOG
                                          earns its acreage within Phase II and
                                          mutually agrees as to a transfer of
                                          lease maintenance responsibility to
                                          PVOG as operator of such wells.

                                          Agreement. The Operating
                                          Agreement-Wellbore shall become
                                          effective for Phase II, Part B upon
                                          the proposal of the first well. The

                                          Part A shall also apply under this
                                          Part B.

                                          3.2.2.1.2 ACREAGE ASSIGNMENT. Prior to
                                          the drilling of each well within Phase
                                          II, Part B for any well covered by
                                          existing GMX acreage, GMX shall
                                          deliver PVOG an assignment for 50% of
                                          GMX's interest (in accordance with the
                                          form attached as Exhibit "D") that
                                          lies within the unit for such well and
                                          GMX HBP acreage . The NRI will be
                                          GMX's recorded lease NRI. The
                                          assignment shall be free of any
                                          burdens, liens or other encumbrances
                                          created by, through and under GMX, but
                                          not otherwise.

         3.3 PHASE III
             ---------

                  3.3.1 FIRST RIGHT OF REFUSAL. The current GMX acreage position
                  in Phase III ("Phase III Acreage") shall be retained by GMX on
                  a 100% working interest basis. However, in the event GMX
                  desires to accept a bona fide offer to sell, trade, farmout,
                  create a joint venture agreement or otherwise dispose any of
                  its Phase III Acreage to an unrelated third party industry
                  partner, then PVOG shall have a first right of refusal to
                  match such offer and shall be subject to the same terms and
                  conditions stated therein, including rights to operate wells,
                  if any. GMX shall notify PVOG of the terms and conditions of
                  such offer within 15 days of receipt of an offer in the form
                  GMX is prepared to accept and provide a copy of such written
                  documentation to evidence such offer. PVOG shall then have
                  fifteen (15) days after receipt of such notice in which to
                  notify GMX of its election to accept or reject such terms and
                  if PVOG does not notify GMX of its election by such date, PVOG
                  shall be deemed to have rejected such offer and GMX may
                  complete the transaction on the terms proposed and any Phase
                  III Acreage transferred shall no longer be subject to this
                  Agreement. The right of first refusal shall not apply to any
                  merger, consolidation, reorganization or sale of all or
                  substantially all of the assets of GMX. Notwithstanding
                  anything herein to the contrary, should GMX accept an offer
                  pursuant to the terms and conditions herein prior to PVOG
                  having the opportunity to complete, at no fault of their own,
                  Phase I, Part A and/or Phase II, Part A, then PVOG shall
                  nevertheless have such first right of refusal as provided
                  herein.

                  3.3.2 RESTRICTION ON ACREAGE ACQUISTION. During the period
                  commencing on the date of this Agreement and ending on the
                  earlier of (i) the date which is one (1) year after the
                  termination of this Agreement, or (ii) the date GMX no longer
                  owns any Phase III Acreage, except as permitted by Section
                  3.3.1, neither PVOG nor any of its affiliates will, without
                  the prior written consent of GMX or as otherwise specifically
                  permitted under paragraph hereof, directly or indirectly, own,
                  acquire or solicit the acquisition of (or assist any other
                  person to own, acquire or solicit the acquisition of) any
                  leases, farmouts, royalty or overriding royalty interests or
                  any interest of any kind relating to oil and gas properties in
                  whole or in part in the Phase III area or conduct (or assist
                  any third person to conduct) any oil and gas business on or
                  with respect to the Phase III area..

                             AREA OF MUTUAL INTEREST
                             -----------------------

         4.1 TERM. The Parties hereby establish an Area of Mutual Interest
         ("AMI") consisting of Phase I and Phase II within the outlines attached
         hereto as Exhibit "A-2". The AMI covering each such Phase shall be
         effective for a term of three (3) years from the Effective Date.

         4.2 ACQUISITIONS. During the term of the AMI, either Party shall have
         the right and authority to acquire oil and gas leases, option
         agreements, mineral interests, royalty interests, farmouts or other
         contracts with respect thereto which affect lands and minerals lying
         wholly or partially within the Phase I and Phase II AMI's ("AMI
         Acreage"). If the acquisition requires drilling, seismic, or other
         operations on the lands lying within the AMI, the election of the
         non-acquiring Party to participate in any acquisition shall be deemed
         an election to participate in the agreement governing such operations,
         to the extent necessary to acquire the interest.

                  4.2.1 PHASE I AMI. Within the Phase I AMI, PVOG will have the
                  right to participate for 70% and GMX the right to participate
                  for 30% on all new leasehold or other acquisitions of Acreage.

                  4.2.2 PHASE II, AMI. Within the Phase II AMI, PVOG shall have
                  the right to participate for 50% and GMX the right to
                  participate for 50% on all new leasehold or other acquisitions
                  of Acreage.

                  4.2.3 ELECTIONS. Each Party shall give the other party notice
                  of any new leases or other Acreage acquisitions made in the
                  AMI on a calendar quarterly basis within 15 days after the end
                  of each calendar quarter, which shall contain a description of
                  the acreage acquired, the terms of any leases and the
                  acquisition cost. Within 25 days after the receipt of such
                  notice, the non-acquiring party shall notify the acquiring
                  party of its election to participate in whole or in part in
                  any new leases or other acquisitions of Acreage that occurred
                  during the quarter. Such elections may not include a
                  fractional interest in any interest acquired. Notwithstanding
                  the foregoing, for new leases or other Acreage acquisitions in
                  a unit in which a well is being drilled or in any contiguous
                  tracts, a separate notice shall be given and the non-acquiring
                  Party shall have 48 hours to notify the acquiring Party of its
                  election to participate. The Party electing to participate in
                  such acquisition shall pay the Party who acquired such
                  interest its proportionate share of the applicable leasehold
                  and/or acquisition costs as follows:

                           4.2.3.1 Land, lease, brokerage, and legal costs
                           incurred within the confines of an existing GMX
                           acreage block (which shall mean any unit or proposed
                           unit in which GMX owns acreage consisting of 50% or
                           more of such unit), the Party electing to participate
                           for its interest shall pay its proportionate share
                           within thirty (30) days of receipt of billing.

                           4.2.3.2 Land, lease, brokerage, and legal costs
                           incurred outside the confines of any existing GMX
                           acreage block but within the AMI, the party electing
                           to participate for its interest shall pay its
                           proportionate share on December 1 for acquisitions
                           during the preceding calendar quarters.

                  Within thirty (30) days after receipt of payment from the
                  non-acquiring Party for the acquired interests, the acquiring
                  Party will deliver to the non-acquiring Party an appropriate
                  assignment. The non-acquiring Party's failure to timely elect
                  or pay its share of costs associated with the acquired
                  interest will be deemed an election by the non-acquiring Party
                  not to acquire such interest.

                                   ----------

         5.1 EXISTING WELLBORES, FLOWLINES, FACILITIES AND COSTS. GMX will
         retain ownership and liability of all existing wellbores, flowlines,
         and facilities associated within the Blocker Prospect. Notwithstanding
         the prior sentence, PVOG shall have the right to take over up to three
         (3) mutually agreeable inactive GMX wellbores to be used for salt well
         disposal purposes in exchange for PVOG assuming the costs of the
         plugging and abandonment of same. GMX agrees to work in good faith to
         make such wells available as needed in each of the Phase areas. In the
         event such flowlines and facilities are needed by PVOG to develop its
         operated wells and assets, the Parties agree to work in good faith to
         mutually agree on a cost structure to account for PVOG's utilization of
         such GMX owned flowlines and facilities.

         5.2 SALT WATER DISPOSAL. PVOG has intentions to install its own salt
         water disposal system within Phase I and possibly Phase II and Phase
         III. Prior to such installation, PVOG will have a right to utilize
         GMX's salt water disposal system in accordance with the terms of the
         saltwater disposal agreement attached hereto as Exhibit F. PVOG's
         access to such system shall be subject to the system capacity needs of
         GMX, but PVOG shall have the right to use any excess capacity.
         Likewise, GMX will have a right to utilize PVOG's salt water disposal
         system on the same terms, with GMX and PVOG having pro-rata rights to
         system capacity based on their respective ownership in the wells being
         served by such system. The Parties agree to negotiate in good faith a
         final Salt Water Disposal Agreement by January 21, 2004.

         5.3 GAS GATHERING. PVOG has intentions to install its own gas gathering
         system within Phase I and possibly Phase II and Phase III. Prior to
         such installation, PVOG will have a right to utilize GMX's gas
         gathering system in accordance with the terms of the gas gathering
         agreement attached as Exhibit G. PVOG's access to such system shall be
         subject to the system capacity needs of GMX, but PVOG shall have the
         right to use any excess capacity. Likewise, GMX will have a right to
         utilize PVOG's gas gathering system on the same terms with GMX and PVOG
         having pro-rata rights to system capacity based on their respective
         ownership in the wells being served by such system. The Parties agree
         to negotiate in good faith a final Gas Gathering Agreement by January
         21, 2004.

                               DISPUTE RESOLUTION
                               ------------------

         6.1 The Parties agree to try to resolve all disputes under this
         Agreement through good faith negotiations. If the negotiations are
         unsuccessful, the Parties agree to submit the resolution of such
         disputes to binding arbitration in Dallas, Texas, in accordance with
         the Commercial Arbitration Rules of the American Arbitration
         Association ("AAA"), including the AAA Optional Rules for Emergency
         Measures of Protection and the Optional Procedures for Large, Complex
         Commercial Disputes.

         7.5 INDEMNITY OF GMX. GMX shall protect, indemnify and hold PVOG
         harmless from and against any liabilities, obligations, claims, losses,
         demands and causes of action arising from or as a result of GMX's
         ownership and operations of the Blocker Prospect, except as may be

         and PVOG. On and after the Effective Date, the Parties shall assume and
         be responsible for liabilities associated with their respective
         ownership and operations within the Blocker Prospect, and shall
         protect, indemnify and hold each other harmless from and against any
         liabilities, obligations, claims, losses, demands and causes of action
         arising or as a result of its ownership and operations in accordance
         with any applicable Operating Agreement between GMX and PVOG.

         7.6 SEVERABILITY. If any provision of this Agreement is held to be
         illegal, invalid or unenforceable under the present or future laws
         effective during the term of this Agreement, then the provision will be
         fully severable; this Agreement will be modified, construed and
         enforced as if the illegal, invalid or unenforceable provision had
         never been in the Agreement; and the remaining provisions will remain
         in full force and effect.

         7.7 NOTICES. Any notices, communications or documents that may be

         7.8 ENTIRE AGREEMENT. This Agreement, including the Exhibits, embodies
         the entire agreement between the Parties, supercedes all prior
         agreements and understandings, if any, relating to the subject matter
         hereof, and may be amended only by an instrument in writing executed
         jointly by an authorized representative of the Parties.

         7.9 CONFIDENTIALITY. All jointly owned well data, geophysical,
         geological and other geoscience data acquired, compiled or generated
         pursuant to and after the Effective Date of this Agreement shall be
         treated as confidential during the term of this Agreement and for a
         period of one (1) year after termination of this Agreement, and shall
         not be sold, traded or otherwise disposed of or divulged without the
         prior written consent of the Party participating in the acquisition of
         such data; provided that access to such data may be made available to a
         party's parent company and/or its subsidiaries, agents, employees,
         contractors engaged in the performance of any work or performing
         services to any Party, a lender or other financing source of a Party or
         any person interested in acquiring a Party or otherwise entering into a
         business transaction with a Party, or to any other person or entity
         where disclosure is required by law. Such jointly owned data shall not
         be available for brokerage, trade or sale until termination of the
         confidentiality obligations specified herein, unless otherwise mutually
         agreed to by all Parties owning the data. If any income or information
         is derived from sale or trade of any jointly owned information, data or
         materials, such information or income shall be shared by the Parties
         participating in their respective interests. A merger, consolidation,
         reorganization or sale of all or substantially all of the assets of a
         Party shall not be considered a sale or disposition of any such data.

         7.10 PARTNERSHIP. The liabilities, obligations, options, elections or
         rights of the Parties hereunder shall be several, not joint or
         collective. It is not the intention of the Parties to create, nor shall
         this Agreement be deemed as creating, a mining, tax or other
         partnership or association or to render the Parties liable as partners.
         However, if for federal income tax purposes, this Agreement and the
         operations contemplated hereunder are regarded as a partnership, each
         Party thereby affected elects to be excluded from the application of
         all of the provisions of Subchapter "K", Chapter 1, Subtitle "A" of the
         Internal Revenue Code of 1986, as amended (hereinafter referred to as
         the "Code"), as permitted and authorized by Section 761 of the Code and
         the regulations promulgated thereunder. Should there be any requirement
         that any Party hereby affected give further evidence of this election,
         each such Party shall execute such documents and furnish such other
         evidence as may be required by the Federal Internal Revenue Service or
         as may be necessary to evidence this election. No Party shall give any
         notice or take any other action inconsistent with the election made
         hereby. In making the foregoing election, each Party states that the
         income derived by such Party from the operations contemplated hereunder
         can be adequately determined without the computation of partnership
         taxable income.

         7.11 PRESS RELEASES. The Parties shall make no press release, public
         announcement or public disclosure relating to this Agreement, except as
         necessary to meet legal or regulatory requirements or as mutually
         approved. The Party electing to issue such press release shall send a
         draft copy to the other Party who will have 48 hours in which to
         comment on such statements. PVOG acknowledges that GMX will make a
         press release relating to this Agreement and that this Agreement will
         be filed as an Exhibit to GMX's reports filed with the Securities and
         Exchange Commission.

         7.12 TERM OF AGREEMENT. Unless earlier terminated pursuant to the
         provisions hereof, this Agreement shall be in effect for the life of
         the leases. The provisions of Sections 3.3.2, 5.2, 5.3, 6.1, 7.9 and
         7.5 shall survive any termination of this Agreement.
