                     INFORMATION NOT REQUIRED IN PROSPECTUS

ITEM 24.  INDEMNIFICATION OF DIRECTORS AND OFFICERS

    The Nevada Revised Statutes and certain provisions of the Company's Bylaws
under certain circumstances provide for indemnification of the Company's
officers, directors and controlling persons against liabilities that they may
incur in such capacities. A summary of the circumstances in which such
indemnification is provided for is contained herein, but this description is
qualified in its entirety by reference to the Company's Bylaws and to the
statutory provisions.

    In general, any officer, director, employee or agent may be indemnified
against expenses, fines, settlements or judgments arising in connection with a
legal proceeding to which such person is a party, if that person's actions were
in good faith, were believed to be in the Company's best interest, and were not
unlawful. Unless such person is successful upon the merits in such an action,
indemnification may be awarded only after a determination by independent
decision of the Board of Directors, by legal counsel, or by a vote of the
stockholders, that the applicable standard of conduct was met by the person to
be indemnified.

    The circumstances under which indemnification is granted in connection with
an action brought on behalf of the Company is generally the same as those set
forth above; however, with respect to such actions, indemnification is granted
only with respect to expenses actually incurred in connection with the defense
or settlement of the action. In such actions, the person to be indemnified must
have acted in good faith and in a manner believed to have been in the Company's
best interest, and must not have been adjudged liable for negligence or
misconduct.

    Indemnification may also be granted pursuant to the terms of agreements that
may be entered in the future or pursuant to a vote of stockholders or directors.
The statutory provision cited above also grants the power to the Company to
purchase and maintain insurance which protects its officers and directors
against any liabilities incurred in connection with their service in such a
position, and such a policy may be obtained by the Company.

the Company during the past three years that were not registered under the
Securities Act.

    (a) The Company issued 995,000 shares in January 1998 pursuant to a
share-for-share exchange with the stockholders of International Metal
Protection, Inc. in a transaction conducted solely to reincorporate the Company
in a new jurisdiction. This transaction was exempt from the registration
requirements of the

                                      II-1
<PAGE>
Securities Act pursuant to Section 4(2) of the Securities Act. There was no
change in ownership and the stockholders made no significant investment
decision.

    (b) The Company issued 500,000 shares in February 1998 for the purchase
price of $.10 per share pursuant to a private placement exempt from the
registration requirements of the Securities Act pursuant to Section 4(2) of the
Securities Act. At that time, the Company had only a business plan and no
assets. There were eleven offerees in this offering, all of whom made purchases
and all of whom were sophisticated investors. The Company fully apprised each of
the offerees of the Company's start-up nature and gave them full details
regarding the Company's business plan. There was no general solicitation or
advertising used in connection with the offer to sell or sale of these
securities. The purchasers were advised that the securities, once purchased,
could not be resold or otherwise transferred without subsequent registration
under the Securities Act. Each purchaser represented to the Company that they
were purchasing the securities for their own account for investment purposes
only.

    (c) The Company issued 4,530,000 shares in February 1998 for a purchase
price of $.22 per share pursuant to a Regulation D, Rule 504 offering. Offerees
were provided with a private placement memorandum containing detailed
information about the Company and its plan. The Company required each
prospective investor to represent in writing that (i) they had adequate means of
providing for their current needs and personal contingencies and had no need to
sell the securities in the foreseeable future and (ii) they, either alone or
with their duly designated purchaser representative, had such knowledge and
experience in business and financial matters that they were capable of
evaluating the risks and merits of an investment in the securities.

    (d) The Company issued 5,000,000 shares in April 1998 for a purchase price
of $1.25 per share pursuant to a Regulation D, Rule 506 offering. The Company
accepted subscriptions only from accredited investors. Offerees were provided

Company and its plan. The Company required each prospective investor to
represent in writing that (i) they had received and reviewed the private
placement memorandum and understood the risks of an investment in the Company;
(ii) they had the experience and knowledge with respect to similar investments
which enabled them to evaluate the merits and risks of such investment, or they
had obtained and relied upon an experienced independent adviser with respect to
such evaluation; (iii) they had adequate means to bear the economic risk of such
investment, including the loss of the entire investment; (iv) they had adequate
means to provide for their current needs and possible personal contingencies;
(v) they had no need for liquidity of their investment in the Company; (vi) they
understood that the securities had not been registered under the Securities Act

laws and, therefore, that they could not sell or transfer the securities unless

available to them; (vii) they were acquiring the securities for investment
solely for their own account and without any intention of reselling or
distributing them; and (viii) they understood that the securities would bear a

services to the Company for one year in return for these warrants.

ITEM 28.  UNDERTAKINGS.

    Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of the
registrant, the registrant has been advised that in the opinion of the
Securities and Exchange Commission such indemnification is against public policy
as expressed in the Act and is, therefore, unenforceable. In the event that a
claim for indemnification against such liabilities (other than the payment by
the registrant of expenses incurred or paid by a director, officer or
controlling person of the registrant in the successful defense of any action,
suit or proceeding) is asserted by such director, officer or controlling person
in connection with the securities being registered, the registrant will, unless
in the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the Act and
will be governed by the final adjudication of such issue.

    The undersigned registrant hereby undertakes:

    (1)  To file, during any period in which offers or sales are being made, a
post-effective amendment to this registration statement: (i) to include any
prospectus required by Section 10(a)(3) of the Securities Act of 1933; (ii) to
reflect in the prospectus any facts or events arising after the effective date
of the registration statement (or the most recent post-effective amendment
thereof) which, individually or in the aggregate, represent a fundamental change
in the information set forth in the registration statement. Notwithstanding the
foregoing, any increase or decrease in volume of securities offered (if the
total dollar value of securities offered would not exceed that which was
registered) and any deviation from the low or high end of the estimated maximum
offering range may be reflected in the form of prospectus filed with the
Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume
and price represent no more than a 20% change in the maximum aggregate offering
price set forth in the "Calculation of Registration Fee" table in the effective
registration statement; and (iii) to include any additional or changed material
information on the plan of distribution.

    (2)  that, for purposes of determining any liability under the Securities
Act of 1933, the information omitted from the form of prospectus filed as part
of this registration statement in reliance upon Rule 430A and contained in a
form of prospectus filed by the registrant pursuant to Rule 424(b)(1) or (4) or
497(h) under the Securities Act shall be deemed to be part of this registration
statement as of the time it was declared effective.


    (3)  that, for the purpose of determining any liability under the Securities
Act of 1933, each post-effective amendment that contains a form of prospectus
shall be deemed to be a new registration statement relating to the securities
offered therein, and the offering of such securities at that time shall be
deemed to be the initial bona fide offering thereto.

reference (the "Subject Lands"), and wishes to drill natural gas wells to
further develop its coalbed methane gas reserves.

         B.   Producer desires to produce and deliver Gas from the Subject Lands
to Gatherer and Gatherer desires to receive and gather from Producer said Gas,
all on the terms and conditions set forth herein.

         NOW THEREFORE, in consideration of the above recitals and the mutual
promises, covenants, commitments, and agreements herein contained, Producer and
Gatherer agree as follows:

                                    ARTICLE I

interest in the Subject Lands, without limitation, as set forth on Exhibit B
hereto and all of Producer's Gas reserves thereunder, for the life of the
production from the Subject Lands, together with any extensions, renewals or
modifications of the Subject Lands, whether now owned or hereafter acquired
during the term of this Agreement.

         C.   The Parties hereto agree to establish an Area of Mutual Interest
("AMI") as depicted on Exhibit C, attached hereto and incorporated herein by
reference. Producer agrees to dedicate to Gatherer, under the terms contained in
this Agreement, all interest currently owned or subsequently acquired by
Producer in lands and/or leases in the AMI whether or not they are described on
Exhibit B hereto. Gatherer agrees to receive and gather all of Producer's Gas
produced from the AMI subject to the terms and conditions set forth in this
Agreement.

         D.   Gatherer shall gather Producer's Gas from the Point(s) of Delivery
and shall redeliver thermally equivalent volumes at the Redelivery Points, less
Fuel, water, and Pipeline Loss as provided in this Agreement. Gatherer shall
have the right but not the obligation to commingle Gas delivered hereunder with
Gas gathered by Gatherer for other producers provided that Producer's Gas is
gathered on a priority basis. However, in the event capacity on a downstream
pipeline is restricted, Producer's Gas will be redelivered as dictated by the
downstream pipeline.

                                   ARTICLE II
                    CONSTRUCTION OF PIPELINE GATHERING SYSTEM

         A.   Gatherer agrees to complete the construction of and equip and
operate sufficient miles of pipeline gathering facilities to connect all of the
wells drilled and produced, or to be drilled and produced, on the Subject Lands
by Producer at the Point(s) of Delivery described on Exhibit D. The original
design of the pipeline gathering facilities to be completed by Gatherer is
intended to be as follows:

           Anticipated production of 250 Mcf/d per well
           Nineteen (19) wells from the Swanson Acreage x 250 mcfd = 4,750 mcfd

                                       2

<PAGE>

           Seventeen (17) wells from the Jim Wolff Acreage x 250 mcfd = 4,250
              mcfd
           Twenty (20) wells from the Harry Wolff Acreage x 250 mcfd =
              5,000 mcfd
           Twenty-eight (28) wells from the Hemela Acreage x 250 mcfd = 7,000
              mcfd
           Twenty-two (22) wells from the Rourke Acreage x 250 mcfd = 5,500
              mcfd
           Compression facilities downstream of the Wellhead Metering
              Facilities to maintain a suction pressure between 0 to 2 psig
           4" SDRI 7 poly pipe from wellhead to Wellhead Metering Facilities

         B.   Gatherer shall have the option to make connections on Gatherer's
Facilities for new Gas developed and produced and saved by Producer on the
Subject Lands described on Exhibit B. If such proposal is to gather such Gas
under the terms and conditions set forth in this Agreement, including, but not
limited to, the design specifications in Article ILA and the service rates and
charges as set forth in Article IV, then such proposal shall be deemed accepted
by Producer. Otherwise, throughout the term of this Agreement, within fifteen
(15) Days from receipt of notice of the completion of sufficient deliverable
quantities of Gas by Producer on the Subject Lands listed on Exhibit B, Gatherer
shall submit a written proposal to Producer to construct and install the
necessary facilities to gather said Gas. Producer shall have 30 Days from
receipt of such proposal to accept or reject Gatherer's proposal for gathering
service hereunder. Failure to respond within the said 30 Day-time period shall
be deemed an election by Producer to reject said proposal.

         C.   Upon receipt of written acceptance of said proposal by Producer or
if such proposal is deemed accepted as provided in Article II.B above, Gatherer
shall commence in a commercially reasonable manner construction and installation
of the gathering facilities necessary to gather Producer's Gas and redeliver
said Gas to the Redelivery Point(s) set forth on Exhibit E, as may be amended
from time to time.

         D.   Should Producer decline the proposal as set forth above, Gatherer
shall not be obligated to make any such connection, and Producer may require
Gatherer to release such well(s) from the Agreement, but only as to the
formation in which such well was originally completed at the time Gatherer
determined the connection to be uneconomic.

         E.   Except for the wells to be connected to the Initial Facilities, in
the event Producer desires Gatherer to connect a group or pod of wells to
Gatherer's Facilities which wells, in Gatherer's sole opinion, would not
constitute an economic connection, Gatherer shall be under no obligation to
connect any such wells, or to accept any Gas therefrom. In the event Gatherer
deems the connection of a group of wells to be uneconomic such that Gatherer
declines to connect such wells, Producer may construct its own field system
connecting such wells and may thereafter connect such facilities to Gatherer's
Facilities. In recognition of the fact that the services required by Gatherer
shall be reduced as a result of Producer's connection, Gatherer's fees for the
services to be provided by Gatherer to complete the gathering of such Gas shall
be appropriately reduced.. In setting these fees, the Parties shall take into
consideration the breakdown of fees set forth in Article IV.

                                       3

<PAGE>


         F.   The term "connect" as used in this Agreement means that
Gatherer shall take custody of Producer's Gas at the Point(s) of Delivery of
each well to be connected to Gatherer's Facilities and shall install such
facilities as are necessary to gather the Gas produced from each such well to
a Wellhead Metering Facility ("WMF") at which the Gas from each well shall be
metered, and from each WMF to the Redelivery Points specified on Exhibit E.
Downstream of each WMF, Gatherer shall install an electronic flow meter to be
used for payment, nominations and imbalance calculations under this Agreement
("Master Meter").

                                   ARTICLE III
                          QUANTITY AND DELIVERY OF GAS

         A.   The Parties agree that certain acreage as described on Exhibit
C is dedicated for redelivery to Western Gas Resources, Inc. ("WGR") under
separate agreement. Gatherer agrees to gather up to 11.0 MMcfd from the WGR
acreage dedication and redeliver said Gas to the interconnect with WGR as
described on Exhibit E. All Gas in excess of 11.0 MMcfd gathered from the WGR
acreage dedication may be gathered and redelivered to any of the proposed
Redelivery Points as described on Exhibit E or any redelivery points that may
be added to Exhibit E from time to time as mutually selected by the Parties
if such Gas is released from dedication by WGR. Gas from the remaining
Subject Lands may be gathered and delivered to any of the proposed redelivery
points as mutually selected by the Parties.

         B.   Producer represents that the Gas to be gathered and redelivered
shall be delivered to Gatherer in conformance with the specifications and
conditions set forth in the Appendix, including Gatherer's Gas quality
specifications.

                                   ARTICLE IV
                            SERVICE RATES AND CHARGES

         A.   Gatherer shall gather and redeliver Producer's Gas and Producer
agrees to pay a gathering fee for redelivery to the interconnect with WGR as
described on Exhibit E. The total gathering fee shall be ******** per Mcf as
measured at each Master Meter until such time as additional redelivery points
other than WGR are available. This gathering fee is comprised of: (i) a fee of
******** per Mcf for gathering service from the wellheads to and through the WMF
as measured at the Master Meter; and (ii) a fee of ******** per Mcf for service
from the WMF to the WGR Redelivery Point as described on Exhibit E as measured
at the Master Meter.

         1.   Upon completion of an interconnect with a proposed redelivery
point described on Exhibit E, Producer agrees to pay a total gathering fee of
******** per Mcf as measured at each Master Meter other than the WGR acreage
dedication Points of Delivery which shall continue to be charged the********
gathering fee. This gathering fee is comprised of: (i) a fee of ******** per
Mcf for service from the wellheads to and through the WMF as measured at the
Master Meter; and (ii) a fee of ******** per Mcf for service from the WMF to
the proposed Redelivery Points as described on Exhibit E as measured at the
Master Meter.

******        This portion of the agreement has been omitted pursuant to a
confidential treatment request that has been filed with the Securities and
Exchange Commission.

                                       4

<PAGE>

         2.   For any WGR acreage dedication Gas in excess of 11.0 MMcfd
requiring additional capital expenditure by Gatherer, the Parties shall
negotiate a mutually agreeable gathering fee.

         3.   For Gas in excess of 11.0 MMcfd that is released from
dedication by WGR and redelivered to any of the proposed Redelivery Points,
Producer agrees to pay a total gathering fee of ******** per Mcf as set forth
above.

         B.   After completion of the Initial Facilities, the total Monthly
gathering fee paid by Producer shall not be less than ******** for the first
Accounting Period, not less than ******** for the second Accounting Period and
not less than ******** for the next fifty-eight (58) Accounting Periods
("Minimum Payments") regardless of the volumes actually delivered to Gatherer.
Should the product of the. actual Monthly volumes as measured at the Master
Meter(s) multiplied by the appropriate gathering fees as set forth in Paragraph
A of this Article IV be less than the Minimum Payment, Gatherer shall invoice
Producer for the remaining balance, payment of which shall be due as provided in
Article VI. Should the product of the actual Monthly volumes as measured at the
Master Meter(s) multiplied by the appropriate gathering fees as set forth in
Paragraph A above be more than the Minimum Payment, Gatherer shall invoice
Producer for the actual Mcf's delivered multiplied by the appropriate gathering
fee set forth in Paragraph A above, payment of which shall be due as provided in
Article VI. The Minimum Payment shall be subject to reduction in the event
Gatherer refuses to accept Gas tendered from Producer which otherwise meets the
specifications of this Agreement, or in the event of a force majeure affecting
Gatherer's facilities which impairs Gatherer's ability to accept Producer's Gas.
No Minimum Payment shall apply during any such Month during which Gatherer's
refusal to accept Gas tendered or Gatherer's force majeure is the cause of
Producer's failure to meet the Minimum Payment.

         1 .   "Initial Facilities" shall be the facilities necessary for
Gatherer to gather Gas produced from the Points of Delivery in the Swanson,
Jim Wolff (should Producer finalize the purchase of such acreage), Harry
Wolff, Hemela and Rourke acreage as described on Exhibit D and redeliver said
Gas to the interconnect with WGR as described on Exhibit E. Gatherer shall
use commercially reasonable efforts to complete the Initial Facilities on or
before April 1, 1999.

         C.   In addition to the foregoing, and not in limitation thereof,
the following additional fees and charges shall be applicable:

              1.   Producer shall reimburse Gatherer for the actual tap fee,
         measurement costs and any associated costs relating to the interconnect
         between Gatherer's Facilities and the Redelivery Point(s). Said
         reimbursement shall be based on Producer's maximum volume requirements
         at each interconnect as provided to Gatherer by Producer in writing.
         Gatherer shall use reasonable efforts to minimize all costs associated
         with said interconnects.

              2.   An alternative power/fuel source fee, in the event any of
         Producer's Gas flows through a compression facility or facilities
         powered by electrical power, or any fuel or power source other than Gas
         being delivered into Gatherer's Facilities, equal to Producer's
         allocable

                                       5

<PAGE>

         portion of the power or alternative fuel costs necessary to operate
         such facility or facilities. Such costs shall be allocated to each
         Point of Delivery by multiplying the total power and fuel cost of each
         compression facility for an Accounting Period by a fraction, the
         numerator of which shall be the volume of Gas flowing through the
         facility attributable to the particular Point(s) of Delivery and the
         denominator of which shall be the total volume of Gas flowing through
         such facilities. Gatherer shall charge Producer, on a Monthly basis,
         the resultant product.

              3.   If treating of the Gas is required, Producer and Gatherer
         shall negotiate a mutually agreeable treating fee.

              4.   Beginning April 1, 2004, the fees described in Paragraph A
         of this Article IV shall be escalated pursuant to changes reflected by
         the Producer Price Index, using as a base such Index as it exists on
         January 1, 2004 as the basis for such adjustment. Escalation of the
         fees set forth in Paragraph A above shall occur annually (on January 1
         of each year) pursuant to adjustments reflected in the Producer Price
         Index. In the event the Producer Price Index is discontinued or
         modified, an index most similar to the Producer Price Index shall
         thereafter be used. However, in no event shall the ******** fee
         described in Paragraph A of this Article IV be greater than ********
         per Mcf and the ******** fee described in Paragraph A above be greater
         than ******** per Mcf.

                                    ARTICLE V
                         NOMINATIONS AND DELIVERY TERMS

         A.   Gas to be delivered by Producer shall be nominated upon terms and
conditions to be agreed upon by the Parties consistent with the requirements of
downstream pipelines. Nominations shall be submitted in writing via facsimile
using the Nomination form attached hereto as the "Nomination Schedule". Producer
shall submit the total volume to be nominated from all Point(s) of Delivery at
least five (5) working Days prior to the first Day of each Month. Unless
required earlier to allow the Parties to meet downstream nomination
requirements, nominations of specified volumes to downstream pipeline(s) shall
be submitted at least one (1) Day prior to the nomination deadline of the
downstream pipeline(s) pursuant to Gas Industry Standards Board ("GISB")
standards. Producer shall give at least twenty-four (24) hours notice of
nomination changes. Producer's nominations shall be confirmed or rejected within
twenty-four (24) hours of receipts Nominations shall not be rejected without
cause. Producer shall use its best efforts to maintain uniform hourly rates of
delivery at all Points of Delivery hereunder to the extent practicable. Gas
shall be measured at the Master Meters and shall meet the specifications as set
forth on the Appendix or as provided by the downstream pipeline.

         B.   To aid Producer in preparation of its Nominations, Gatherer shall
from time to time as Producer may reasonably request, provide Producer with its
best, good faith estimate of the amount of Pipeline Loss and Fuel Gas
anticipated to occur from the Points of Delivery to the Redelivery Point(s).

******        This portion of the agreement has been omitted pursuant to a
confidential treatment request that has been filed with the Securities and
Exchange Commission.

                                       6

<PAGE>

         C.   In addition to its nominations for deliveries to Gatherer at
the Point(s) of Delivery, Producer shall also submit to Gatherer nominations
for delivery to the Redelivery Point(s) as set forth on the Nomination
Schedule based upon Gatherer's estimate of Fuel Gas and Pipeline Loss. Such
nominations at the Redelivery Point(s) shall be consistent with those issued
by Producer to. each pipeline company accepting Producer's Gas at each
respective Redelivery Point. Recognizing that operating conditions may from
time to time result in actual deliveries by Producer at the Point(s) of
Delivery or the Redelivery Point(s) in amounts greater or less than those so
nominated, the following procedures, rights and obligations shall apply:

              1.   Gatherer shall attempt to verify that the amounts nominated
         by Producer to Gatherer hereunder as reflected on the Nomination
         Schedule and nominated to the pipeline company accepting Producer's Gas
         at the Redelivery Point(s) are consistent. Producer and Gatherer shall
         communicate and cooperate to insure that any discrepancy in those
         nominations shall be promptly reported to each other and the pipeline
         company accepting Producer's Gas at the Redelivery Point(s).

              2.   Gatherer shall operate its Facilities in order to accept and
         redeliver Gas hereunder in such a way as to maintain balance on its
         Facilities as between receipts and redeliveries of Gas subject to the
         Agreement as closely as possible. Gatherer shall have the right to
         refuse to accept volumes if Producer's deliveries exceed its
         nominations, or to refuse to confirm nominations if nominations exceed
         deliveries. Nothing herein shall be construed to require Gatherer to
         deliver Gas to any Redelivery Point(s) in excess of that actually
         received by Gatherer from Producer at the applicable Point(s) of
         Delivery.

              3.   Gatherer shall include in its Monthly statement of Producer's
         metered volumes at each WMF, Producer's allocated share of the Gas
         metered at each Master Meter, Fuel Gas, Pipeline Loss on Gatherer's
         Facilities, and the Gas allocated to Producer at each Redelivery Point.
         The difference between the sum of Producer's allocated share of Gas
         metered at each Master Meter and the sum of the Gas allocated to
         Producer at each Redelivery Point, less Pipeline Loss and Fuel Gas
         shall constitute Producer's imbalance on Gatherer's Facilities. The
         Parties shall endeavor to balance Thermally Equivalent volumes of Gas
         received and redelivered for Producer as nearly as feasible. Gatherer
         and Producer shall cooperate to eliminate any cumulative imbalance as
         soon as is practicable after the Monthly accounting of the cumulative
         imbalance. If Gatherer has received less Gas than it has credited to
         Producer at the Redelivery Points, then Producer shall increase
         deliveries to Gatherer or decrease nominations in order to eliminate
         such imbalances. If Gatherer has received more Gas than has been
         credited to Producer at the Redelivery Points, then Producer shall
         decrease deliveries to Gatherer or nominate increased volumes in order
         to eliminate such imbalance.

              4.   In recognition that Gas gathered under this Agreement is
         purchased from, sold to, or transported by third parties, Producer and
         Gatherer shall use reasonable efforts to cause each such third party to
         cooperate fully with the Parties' efforts to maintain balance on
         Gatherer's Facilities.

                                       7

<PAGE>

              5.    If deemed necessary by the Parties, Gatherer shall use
         reasonable efforts to enter into Operational Balancing Agreements with
         downstream transporters at such Redelivery Point(s) so that Producer
         may be credited at such Redelivery Point(s) with its confirmed
         nominations for such point. Additionally, Gatherer represents that all
         producers who are or may be connected to the Gatherer's Facilities are
         or will, upon connection, be subject to provisions similar to those in
         subparagraphs 1 through 4 above. Gatherer agrees to enforce such
         provisions on a nondiscriminatory basis so as to minimize imbalances on
         Gatherer's Facilities and the risk of downstream imbalances for all
         parties whose gas is gathered by Gatherer.

              6.   Gatherer shall keep accurate records of the quantities of
         Gas nominated and scheduled for gathering and any imbalances, which
         records shall be reported to Producer on a Monthly basis. If Producer's
         Gas is commingled with other gas at the Point(s) of Delivery, the
         wellhead operator shall provide Gatherer with the allocation of the Gas
         at such Point. If Producer's Gas is commingled with other gas at the
         Redelivery Point(s), Gatherer shall provide the operator of the
         downstream facilities at such Redelivery Point(s) with the allocation
         of such Gas. Such allocation shall be based upon the methodology set
         forth in Section 8 of the Appendix.

              7.   Gatherer and Producer recognize that the primary obligation
         and burden of responsibility to monitor, control, adjust and maintain a
         concurrent balance between nominations and deliveries of Gas shall rest
         with Producer. Therefore, except to the extent otherwise set forth
         above, Gatherer does not assume, by the provisions of this section, the
         responsibility or obligation to monitor or adjust Producer's
         nominations or deliveries.

              8.   Except as provided in subparagraph 9 below, Gatherer shall
         not be liable for any penalties and charaes incurred by Producer with
         any downstream pipeline to which Gatherer is delivering Producer's Gas.
         Producer agrees to indemnify and hold harmless Gatherer, its parents,
         members, subsidiaries and affiliate corporations or entities, and their
         respective officers, directors, employees, members and agents, and
         co-venturers (if any) in the performance of this Agreement, from and
         against any and all claims, causes of action, penalties, liabilities,
         damages and losses pertaining to such penalties and charges.

              9.   All penalties and charges incurred by Producer with any
         downstream pipeline to which Gatherer is delivering Producer's Gas by
         reason of Gatherers failure to deliver Producer's nominated volumes
         which were properly delivered to Gatherer by Producer shall be the sole
         responsibility of Gatherer. Gatherer agrees to indemnify and hold
         harmless Producer, its parents, members, subsidiaries and affiliate
         corporations or entities, and their respective officers, directors,
         employees, members and agents, and co-venturers (if any) in the
         performance of this Agreement, from and against any and all claims,
         causes of action, penalties, liabilities, damages and losses pertaining
         to such penalties and charges.

                                   ARTICLE VI


                                       8

<PAGE>



                             STATEMENTS AND PAYMENTS

         A.   On or before the fifteenth (15th) Day of each Accounting Period,
Gatherer shall send to Producer a statement of charges for Gas gathering and
other services rendered hereunder in the previous Accounting Period along with
any Minimum Payment due Gatherer under this Agreement.

         B.   Producer shall pay Gatherer by Electronic Funds Transfer to a
designated bank account established by Gatherer. Payments shall be made by
Producer to Gatherer within ten (10) Days from the date on which the statement
is received ("Due Date") for all charges billed. Payments made by Electronic
Funds Transfer shall be considered to have been made on the date when such
payment of good funds is received by Gatherer. To avoid uncertainty respecting
date of receipt of statements, Gatherer may fax its statement and the fax
confirmation date shall be deemed the date of receipt.

         C.   Should Producer fail to pay part or all of the amount of any such
statement, interest thereon shall accrue on the unpaid balance at the prime rate
per annum. plus two percent (2%) compounded on a quarterly basis. For purpose
hereof, the prime rate shall be that rate established by BankBoston N.A. as the
most favorable rate available to business customers, such rate to change upon
each announced rate change; provided, that the interest rate to be applied to
unpaid balances hereunder shall not exceed the maximum rate permitted under
Colorado law. If such failure to pay continues thirty (30) Days after payment is
due, Gatherer, in addition to any other remedy it may have may suspend further
service to Producer until such amount is paid after Gatherer provides Producer
with ten (10) Days prior written notice; provided, however, that if Producer in
good faith disputes in writing the amount of any such statement or parts thereof
and pays to Gatherer such amounts as it concedes to be correct, and at any time
thereafter within thirty (30) Days of demand made by Gatherer shall furnish a
good and sufficient surety bond guaranteeing payment to Gatherer of the amount
ultimately found due upon such statements after a final determination, which may
be reached either by Agreement or judgment of the courts as may be the case,
then Gatherer shall not be entitled to suspend service on account of failure to
pay such charges unless and until default be made in the conditions of such
bond. If resolution of the dispute is in favor of Producer and Producer
furnished a surety bond instead of paying the disputed amount, then Gatherer
shall reimburse Producer for the cost of securing that surety bond. No payment
by Producer of the amount of a disputed bill shall prejudice the night of either
Party to claim an adjustment of the disputed statement.

         D.   In the event that an error is discovered in the amount billed or
paid hereunder, such error shall be adjusted within thirty (30) Days of the
determination thereof, provided that claim therefor shall have been made within
twenty-four (24) Months from the date of the applicable billing.

         E.   Each Party shall preserve for a period of at least two (2)
years on a rolling basis all test data, charts, and other similar records
relating to each Accounting Period for audit purposes. After twenty-four (24)
Months, all data, charts, and other similar records pertaining to a
particular Accounting Period shall be presumed to be correct, unless written
notice of contest is presented to Gatherer within said time period.

         F.   Either Party, upon thirty (30) Days prior written notice and upon
execution of a confidentiality agreement, a form of which is attached hereto as
Exhibit F, shall have the right, at reasonable times during business hours, but
no more frequently than once each calendar year, at its expense, to examine the
books and records of the other Party to the extent necessary to audit and verify
the accuracy of any statement, charge, or computation made under or pursuant to
this Agreement. The scope of such audit shall be limited to the twenty-four (24)
Month period prior to the Month in which such audit commences. All statements,
allocations, measurements, and payments made in any period prior to the
twenty-four (24) Months preceding such Month shall be conclusively deemed true
and correct. The Party conducting the audit shall have six (6) Months after
commencement of the audit in which to submit a written claim, with supporting
detail, for adjustments.

<PAGE>

                                      TERM

         A.   This Agreement shall be in full force and effect as of the
Effective Date and shall continue and remain in full force and effect
thereafter for the life of production from the Subject Lands.

                                    ARTICLE IX
                                SPECIAL PROVISIONS

         A.   The Parties acknowledge that maximum online performance of
Gatherer's Facilities is important to Producer's ability to maximize production
from the Subjects Lands. In recognition thereof, Gatherer agrees to an online
performance of Gatherer's Facilities of ninetyeight percent (98%) of the hours
in each Month for which Producer delivers volumes of Gas to Gatherer in
quantity, quality and at a pressure which do not prevent Gatherer from
performing its responsibilities under the terms of this Agreement.

              One hundred percent (100%) online performance for a single
              compressor is considered to be seven hundred thirty (730)
              hours per Month. The online performance of Gatherer's
              Facilities shall be calculated by multiplying a fraction, the
              numerator of which is the aggregate runtime hours of all
              compressors on Gatherer's Facilities plus aggregate downtime
              hours for reasons listed in subparagraph A.1 of this Article
              IX and the denominator of which is the number of compressors
              multiplied by seven hundred thirty (730) hours, by one hundred
              (100) (conversion to percent).

              EXAMPLE OF ONLINE PERFORMANCE PERCENTAGE CALCULATION:

         (AGGREGATE RUNTIME HRS + EXCLUDED AGGREGATE DOWNTIME HRS) x 100
                  = Percent Runtime Number of Units x 730 hours

         1.   Online performance will be calculated EXCLUDING the following:

                  -    Conditions of force majeure as defined in Section 11 of
                       the Appendix;
                  -    Conditions in Producers facilities at the Leases having
                       the effect of substantially reducing the volumes of Gas
                       delivered to Gatherer, or having the direct effect of
                       disrupting the operations of Gatherer;
                  -    Shutdown of Gatherer's Facilities for routine maintenance
                       (not to exceed four (4) hours per Month per unit) or
                       overhaul maintenance (not to exceed two (2) Days per
                       calendar year per unit), any other prudent and necessary
                       operation reason or for modification, expansion or
                       replacement.

              Gatherer shall reduce Producer's gathering fee by two-tenths of
              one cent ($.002) for every one percent (1%) of online performance
              below ninety-eight percent (98%). The

                                       11

<PAGE>

              reduction in fees shall be calculated down to an online
              performance of ninety percent (90%).

         B.   If Gatherer is unable to maintain online performance of ninety
percent (90%) as described in Paragraph A of this Article IX for any three
(3) Months within a six (6) Month period, Producer may provide written notice
of such non-performance and Gatherer shall have thirty (30) Days to remedy
such non-performance. Should Gatherer fail to remedy the non-performance
Producer shall have the option to purchase Gatherer's Facilities based on
Gatherer's projected cash flow discounted at a fifteen percent (15%) present
value over twenty (20) years. In no event shall the amount paid by Producer
to Gatherer for Gatherer's Facilities be less than one hundred fifty percent
(150%) of Gatherer's original book value for Gatherer's Facilities.

<PAGE>

              the complete combustion, at constant pressure, of the amount of
              Gas which would occupy a volume of one (1.0) cubic foot at a
              temperature of sixty degrees (60DEG) Fahrenheit saturated with
              water vapor and under a pressure of 14.73 Psia with air of the
              same temperature and pressure as the Gas, when the products of
              combustion are cooled to the initial temperature of the Gas and
              air and when the water formed by combustion is condensed to the
              liquid state.

         10)  "MCF" shall mean one thousand (1,000) cubic feet of Gas at a
              temperature of sixty degrees (60DEG) Fahrenheit and under a

              pursuant to adjustments reflected by the Producer Price Index
              shall only be increased, notwithstanding any decrease in Index.

         16)  "PSIA" shall mean pounds per square inch absolute.

         17)  "PSIG" shall mean pounds per square inch gauge.

         18)  "PIPELINE LOSS" shall mean the volume reduction in the Gas
              resulting from unaccounted for losses.

2.       POINT(S) OF DELIVERY, PRESSURE AND OWNERSHIP

         A.   The "Point(s) of Delivery" for all Gas delivered under the
Agreement shall be at the discharge of Producer's individual wellhead valves.

         B.   Producer, at its own expense, shall equip, maintain and operate
all facilities to deliver Producer's Gas to Gatherer at the Point(s) of
Delivery, including, but not limited to, installation and maintenance of
Producer's gathering facilities and mechanical separation equipment

         C.   Except as otherwise provided in the Agreement, Gatherer shall
construct, maintain, own and operate all necessary facilities to accept
Producer's Gas from Producer at the Point(s) of Delivery. Gatherer shall keep
Gatherer's Facilities reasonably clear of obstruction.

         D.   Gatherer has designed the original facilities to maintain
between 0 and 2 psig of pressure at the suction of the compressor described
in Article II.A of the Agreement and will similarly design facilities under
Article II.B. Provided Producer's production does not materially deviate from
such design specifications, if the Monthly average suction pressure when the
compressor is operating is greater than 2 psig, Gatherer shall take immediate
steps to reduce said pressures and shall inform Producer of the nature of
such steps. If Producer's production does materially deviate from the design
specifications, Gatherer may not be able to maintain the referenced suction
pressure; however, the Parties will work together to address any resulting
pressure issues. Furthermore, in the event Producer determines other
conditions on Gatherer's Facilities are excessively limiting production,
Producer shall provide written notice to Gatherer and Gatherer shall have
thirty (30) Days to provide in writing a suggested remedy to alleviate said
conditions. If Gatherer's suggested remedy is unacceptable to Producer,
Producer shall have the right to install the necessary facilities for remedy,
at Producer's sole cost and expense.

                                       2.A

<PAGE>

         E.   Producer shall deliver Gas at the Point(s) of Delivery at a
pressure sufficient to enter Gatherer's Facilities, but not to exceed the
maximum allowable operating pressure ("maop") of the pipe. Gatherer shall not
be obligated to redeliver the Gas at pressures which exceed 100 psig for Gas
that is redelivered to Redelivery Point(s) demanding the******** gathering
fee and 1,250 psig for Gas that is redelivered to Redelivery Point(s)
demanding the ******** gathering fee as set forth in Article IV.A and IV.A.1
of the Agreement. Should the Parties elect to utilize only the proposed
"Thunder Creek" Redelivery Point and should Gatherer's Facilities be designed
to redeliver Gas at approximately 500 psig, the Parties agree to discuss
reduction of the gathering fee to such Redelivery Point.

         F.   As between the Parties, Producer shall be in possession and
control of the Gas deliverable under the Agreement and responsible for any
injury or damage caused thereby until the same shall have been delivered to
Gatherer, after which delivery Gatherer shall be deemed to be in exclusive
possession and control thereof and responsible for any injury or damage
caused thereby.

3.       RESERVATIONS AND COVENANTS OF PRODUCER

         A.   Producer, as a reasonable and prudent operator, hereby expressly
reserves the following rights with respect to Producer's interest in the Subject
Lands:

              1)    The right to use the Gas produced from the Leases prior to
                    delivery to Gatherer for the following purposes:

                    a)    For fuel in the drilling, development and operation of
                          the Subject Lands from which the Gas is produced, or
                          within the boundaries of any unit plan or operation to
                          which any portion of the Leases may be committed,
                          excluding, however, the use of such Gas for secondary
                          or tertiary recovery projects;

                    b)    For delivery to the lessors of the leases of the Gas
                          if such lessors are entitled to use or take such Gas
                          in kind under the terms of the leases and agreements
                          associated with the Subject Lands;

                    c)    For fuel in the operation of the facilities which
                          Producer may install in order to deliver Gas hereunder
                          in accordance with the terms hereof.

              2)    The right to pool or unitize the Subject Lands (or any
                    portion thereof) with other lands and leases so long as such
                    action does not reduce Producer's interest in the Subject
                    Lands. In the event of any such pooling or unitization, the
                    Agreement will cover Producer's interest in the pool or unit
                    and the Gas attributable thereto to the extent that such
                    interest is derived from Producer's Subject Lands.

         B.   Producer shall provide to Gatherer all necessary information
whereby Gatherer can make the proper allocation herein called for or required
by Gatherer's normal and customary accounting practices or required by
Gatherer's normal and customary contract administration practices.

         C.   Producer shall operate the Subject Leases free of any control by
Gatherer, including without limitation, the right to make farmouts of any lease
subject to this Agreement, and to abandon any well and surrender any lease when
Producer deems the same no longer capable of producing Gas in commercial
quantities under normal methods of operation. Producer shall not be required to
produce any well or wells in any manner which in its sole judgment and
discretion would not constitute good operating practice, nor shall Producer be
obligated to drill additional wells or to deepen, repair or rework any existing
wells.

4.       PRODUCER'S WARRANTIES

         A.   The Parties recognize that uncertainties may exist with respect to
ownership of coalbed methane gas. However, as between the Parties hereto,
Producer warrants that Producer has the right to deliver said Gas and that such
Gas is free from all liens and adverse claims, including liens to secure
payments of production taxes, severance taxes, and

******        This portion of the agreement has been omitted pursuant to a
confidential treatment request that has been filed with the Securities and
Exchange Commission.

                                       3.A

<PAGE>

other taxes. Producer agrees to indemnify Gatherer and save it harmless from all
suits, actions, debts, accounts, damages, costs, losses and expenses arising
from or out of adverse claims, whether meritorious or not, of any and all
persons, firms, or corporations to said Gas or to royalties, overriding
royalties, taxes, license fees, or charges thereon, resulting from actions of,
by, through or under Producer. Gatherer shall be entitled to recover all costs
and reasonable attorneys' fees incurred as a result of its involvement in any
action or claim described herein.

5.      EASEMENTS

         A.   To the extent that it may contractually or lawfully do so under
its leasehold interest without impairing its own similar right, Producer
hereby assigns and transfers to Gatherer any easement across the Producer's
Subject Lands, and across any adjoining lands in which Producer may have an
interest, for the purposes of installing, using, inspecting, repairing,
operating, replacing, and/or removing Gatherer's pipe, meters, lines, and
other equipment used or useful in the performance of the Agreement It is
intended that any property of Gatherer placed in or upon any of such land
shall remain the personal property of Gatherer, subject to removal by it upon
the expiration or termination of the Agreement for any reason. Gatherer shall
have a reasonable time after the expiration or termination of the Agreement
to remove same. Gatherer shall indemnify and hold Producer harmless of and
from any and all claims and damages for all injuries to persons, including
death, or damage to property arising out of or incident to Gatherer's use of
the easement hereunder transferred to the extent said claim or damage shall
be the result of intentional acts of Gatherer, its employees, agents and
representatives or negligence legally imputable to Gatherer, its employees,
agents, and representatives.

6.       PIPELINE LOSS

         A.   Gatherer agrees to use ordinary care in gathering Producer's Gas
from the Point(s) of Delivery to the Redelivery Point(s) nominated. However, the
Parties understand and agree that certain losses in the Gas will occur and shall
be shared by and among Producer and other third parties whose gas is gathered to
the Redelivery Point(s), in the proportion that each party delivers gas into
Gatherer's Facilities at their respective Master Meter(s). Pipeline Loss shall
be determined by subtracting the total Mcf's measured at the Redelivery Point(s)
from the total Mcf's measured at all Master Meter(s) less actual Fuel Gas
consumed in Gatherer's Facilities.

         EXAMPLE OF PIPELINE LOSS CALCULATION:
         (Master Meter Mcf - Actual Fuel Gas Consumed) - Redelivery Point(s)
         Mcf's = Pipeline Loss(/Gain)

         Pipeline Loss shall be calculated on a twelve (12) Month rolling
average beginning with the first Month following initial deliveries. The
twelve (12) Month rolling average Pipeline Loss for Gas shall not be greater
than three percent (3%) of the Gas measured at the Master Meter(s). In the
event Pipeline Loss is greater than three percent (3%), Gatherer shall pay
Producer a price equal to Producer's weighted average sales price at the
Redelivery Point for which Producees proportionate share of the Pipeline Loss
Mcf's is in excess of three percent (3%). Said price shall be paid only for
the volumes in excess of three percent (3%).

7.       GAS MEASUREMENT AND QUALITY

         A. Gatherer, at its expense, shall furnish, install, operate and
maintain suitable measurement at Gatherer's WMFs and separate Master Meters
downstream of the WMFs including electronic flow measurement recording devices.
Each meter installed by Gatherer shall be a meter acceptable in the industry and
each meter shall be installed and operated in accordance with the requirements
of applicable provisions in ANSI/API 2530, "ORIFICE METERING OF NATURAL GAS"
(American Gas Association Gas Measurement Committee Report No. 3) of the Natural
Gas Department of the American Gas Association, as amended from time to time, or
by any other method commonly used in the industry and mutually acceptable to the
Parties. Any meter installed hereunder shall be open to inspection by Producer
at all reasonable times. The charts and records pertaining to measurement
hereunder shall be kept on file by Gatherer for a period of two (2) years for
the mutual use of the Parties. In the event any question arises as to the
accuracy of the measurement, the meter or meters shall be tested upon the demand
of either Party. The expense of any such special test shall be borne by the
Party demanding same if the meter registration is found to be correct, and by
Gatherer if found to be incorrect.

                                       4.A

<PAGE>

         B.   Producer may, at its option and sole expense, install, maintain
and operate check meters and other equipment to check Gatherer's meters;
provided, however, that such check meters and other equipment shall be
installed by Producer so as not to interfere with the operation of any of the
Gatherees Facilities. Gatherer and Producer shall have access to each other's
measuring equipment at all times during business hours, but the reading,
calibrating and adjustment thereof and the changing of charts shall be done
only by the employees or agents of Gatherer and Producer, respectively, as to
meters or check meters so installed hereunder.

         C.   At least semi-annually, unless otherwise required by statute,
Gatherer shall verify the calibration of all meters installed hereunder and make
adjustments as necessary. Should Producer so desire, Gatherer shall give notice
to Producer of the time of such calibrations sufficiently in advance of holding
same in order that Producer may have its representative present. With respect to
any test made hereunder, a registration within two percent (2%) of correct shall
be considered correct. However, the meter or meters, when found to be incorrect,
shall be adjusted to one hundred percent (100%) accuracy as soon as possible.
Settlement for any period during which the meter registration deviates by more
than two percent (2%) of correct shall be corrected at the rate of inaccuracy
for any period of inaccuracy which is definitely known or agreed upon; but in
case the period is not definitely known or agreed upon, then either for a period
of fifteen (15) Days prior to the date of said test, or for a period calculated
from the beginning of the Accounting Period in which the test was conducted,
whichever is longer. The rate of the inaccuracy shall be estimated and agreed
upon by the Parties hereto on the basis of the best available data, using the
first of the following methods which is feasible:

              1)    By using the registration of any check meter or meters if
                    installed and accurately registering; or, in the absence
                    thereof,

              2)    By calibration, test, or mathematical calculation; or

              3)    By estimation based on comparison of the quantity of
                    deliveries with deliveries during preceding periods
                    under similar conditions when the meter was registering
                    accurately.

         D.   All fundamental constants, observations, records and procedures
involved in the determination and/or verification of the quantity and other
characteristics of Gas measured hereunder, unless otherwise specified herein,
shall be in accordance with the applicable provisions in ANSI/API 2530, "ORIFICE
METERING OF NATURAL GAS" (American Gas Association Gas Measurement Committee
Report No. 3) of the Natural Gas Department of the American Gas Association, as
amended from time to time, or by any other method commonly used in the industry
and mutually acceptable to the Parties. The average local atmospheric pressure
shall be assumed to be 12.7 Psia. The temperature of Gas flowing through each
meter shall be determined by a recording thermometer, installed by Gatherer at
its sole cost and expense to properly record the temperature of the flowing Gas,
and the arithmetical average of the temperature recorded while the Gas is
flowing during each meter chart interval shall be used in correcting amounts
delivered hereunder to a temperature base of sixty degrees Fahrenheit (60DEGF)
and to a pressure base of 12.7 pounds Psia. Should the recording thermometer
malfunction, Gatherer shall assume a reasonable temperature for the period in
question.

         E.   Producer agrees that Gas delivered to the Redelivery Point(s)
shall comply with the most stringent quality specifications of the downstream
pipelines. To the extent the downstream pipelines is willing to accept
non-conforming Gas, Gatherer will gather and redeliver such non-conforming
Gas. To the extent the downstream pipelines will only accept a certain
quantity of non-conforming Gas, Gatherer will gather and redeliver such
quantities of non-conforming Gas.

         F.   Gatherer may test Producer's Gas delivered hereunder for adherence
to the specifications referenced above, such testing to be in accordance with
generally accepted industry standards and procedures. If the Gas so delivered by
Producer does not meet the specifications set forth above, Gatherer, at its
option, may refuse to accept delivery of said Gas into its Facilities. If
Producer shall deliver Gas to Gatherer which exceeds the maximum pressure
specifications, or fails to meet the quality specifications above-referenced,
Producer shall be responsible for any damages caused to Gatherer's Facilities
and any other damages resulting from Producer's delivery of such non-conforming
Gas. In such event, Producer shall have the right to conform Producer's Gas to
the above specifications. Should Producer fail to do so, Gatherer, at its
option, may elect to accept such nonconforming Gas, condition the same to
conform to the above specifications and charge Producer a mutually acceptable
conditioning fee. If neither Party elects to condition the Gas to conform to the
above specifications, then Producer, at its option, and upon sixty (60) Days
prior written notice to

                                       5.A

<PAGE>



Gatherer, shall have the right to obtain the release of such non-conforming Gas
from the Agreement, but only as to the formation from which said Gas is
produced. Notwithstanding anything hereinabove to the contrary, should Gatherer
elect to accept and pay for nonconforming Gas, Gatherer shall not be deemed to
have waived any of its rights hereunder and shall nevertheless be entitled, at
any time and from time to time, to enforce the quality provisions hereof and
refuse to accept delivery of any volumes of non-conforming Gas from Producer.

         G.   At least semi-annually, unless otherwise required by statute,
Gatherer shall take samples from each of Producer's wells at the WMF's and have
such samples analyzed by chromatograph analysis to determine the liquids content
by component and the Gross Heating Value of such Gas. Gatherer shall have the
right to take and analyze a spot Gas sample prior to the regularly scheduled
sampling. Additionally, upon Producer's written request to Gatherer and at
Producer's sole cost, risk and expense, Gatherer shall take and analyze Gas
samples more frequently. All Gas samples taken hereunder shall be taken at such
times that are reasonably mutually agreeable so that the sample will be
representative of the Gas produced, shall be analyzed using the most current Gas
Processor's Association Publications and Producer shall be permitted to be
present for such sampling and permitted to take a split sample. The test samples
shall be analyzed through the use of a calorimeter (acceptable to both Parties)
that employs the Thomas Principle of Calorimetry described in Research Paper
#519, published by the U.S. Department of Commerce or by the use of gas
chromatography equipment The Gross Heating Value calculation will use the Btu
values assigned to the various hydrocarbon components as adjusted and updated
from time to time by Gatherer using as a base those values set forth in the most
current GPA Publication 2145 in effect at the time the Gross Heating Value
calculation is derived under the provisions of the Agreement Measurement shall
be determined as delivered on a saturated basis or consistent with the basis
applied to all producers delivering gas to Gatherer's Facilities. Gatherer shall
furnish Producer advance notice of the sampling and analysis of the Gas in order
that Producer may witness same. If Producer's representative is not present,
Gatherer shall proceed with the taking and analysis of samples. All gas which
may be delivered by third parties to Gatherer's Facilities shall be tested and
the hydrocarbon content thereof determined or caused to be determined by
Gatherer, using the same sampling and test methods.

         H.   Measurement of the redelivered Gas will be accomplished by
suitable meters installed, maintained and operated by the third party
receiving pipeline company(ies). Gatherer will perform periodic analysis and
joint meter tests semi-annually, unless otherwise required by statute, to
insure the third party receiving pipeline company's(ies') compliance with
standard industry practices. Should Gatherer be refused the right to install
a check recorder on third party receiving pipeline company(ies) meter
tube(s), the three percent (3%) Pipeline Loss as set forth in Section 6.A
above shall be waived.

8.       ALLOCATION OF GAS

         A.   The volume received at each Point of Delivery shall be
allocated by multiplying the actual volumes measured at each Master Meter by
a fraction, the numerator of which is the volume attributable to each
particular Point of Delivery, and the denominator of which is the total
volume attributable to all Points of Delivery behind each Master Meter.
Further, the MMBtu's received at each Redelivery Point shall be allocated by
multiplying the actual MMBtu's received at the Redelivery Point(s) by a
fraction, the numerator of which is the MMBtu attributable to each particular
Master Meter, and the denominator of which is the total MMBtu attributable to
all Master Meters into Gatherer's Facilities.

9.       PRODUCER'S REPRESENTATIVE

         A.   The Producer shall designate a representative with respect to all
matters under the Agreement, including but not limited to the following:

              1)    To give and receive all notices;

              2)    To make and witness any tests to be made of Producer's Gas
                    and measuring equipment and adjustments to such equipment;

              3)    To deliver the quantities of Producer's Gas deliverable
                    hereunder;

                                       6.A

<PAGE>


              4)    To comply with the requirements, rules and regulations of
                    any duly constituted authority having jurisdiction.

         B.   Gatherer may act, and shall be fully protected in acting, in
reliance upon any and all acts and things done and performed by or agreements
made with respect to all matters dealt with herein by said representative on
behalf of Producer as fully and with the same effect as though Producer had
done, performed, made or executed the same.

         C.   Producer may change its representative designated above, or
designate a new representative from time to time by delivery of written notice
of change and designation of representative to Gatherer. The representative so
designated shall have and may exercise all power and authority therein granted
with like effect as though named as such representative herein in the first
instance.

10.      REGULATORY BODIES

         A.   The Agreement is subject to all present and future valid laws and
lawful orders of all regulatory bodies now or hereafter having jurisdiction of
the Parties, or either of them; and should either of the Parties, by force of
such law or regulation imposed at any time during the term of the Agreement, be
ordered or required to do any act inconsistent with the provisions of the
Agreement, the Agreement shall continue nevertheless and shall be deemed
modified to conform with the requirements of such law or regulation for that
period only during which the requirements of such law or regulation are
applicable. Nothing in the Agreement or this Appendix shall prohibit either
Party from obtaining or seeking to obtain modification or repeal of such law or
regulation or restrict either Party's right to legally contest the validity of
such law or regulation, and each Party reserves the right to file with such
regulatory bodies any material necessary to implement the terms of the Agreement
and this Appendix as they existed prior to the modification.

11.      FORCE MAJEURE

         A.   Except for Gatherer's and Producees respective obligations to make
proper settlement, accounting and distribution of proceeds to all interest
owners as provided above for Gas delivered to and gathered by Gatherer under the
Agreement, in the event either Gatherer or Producer is rendered unable, by
reason of an event of force majeure, to perform, wholly or in part, any
obligation or commitment set forth in the Agreement, then upon such Party giving
notice and full particulars (including all supporting documentation) of such
event as soon as practicable after the occurrence thereof, the obligations of
both Parties shall be suspended to the extent and for the period of such force
majeure provided that the Party claiming an event of force majeure shall make
all reasonable attempts to remedy the same with all reasonable dispatch.

         B.   The term "FORCE MAJEURE", as used herein, shall mean acts of God,
strikes, lockouts or industrial disputes or disturbances, civil disturbances,
arrest and restraint of rulers or people, interruptions by government or court
orders, necessity for compliance with any present and future valid orders of
court, or any law, statute, ordinance or regulation promulgated by any
governmental or regulatory authority having proper jurisdiction, acts of the
public enemy, wars, riots, blockades, insurrections, including inability to
secure materials by reason of allocations promulgated by authorized governmental
agencies, epidemics, landslides, lightning, earthquakes, fires, storms, floods,
washouts, inclement weather which necessitates extraordinary measures and
expense to construct facilities and/or maintain operations, explosions, partial
or entire failure of Gas supply, breakage or accident to machinery or lines of
pipe, freezing of wells or pipelines, inability to obtain or delays in obtaining
easements or rights-of-way, the shutting in of facilities for the making of
repairs, alterations or maintenance to wells, pipelines or plants, the
interruption or suspension of the receipt of Gas deliveries hereunder by
Gatherer due to the declaration of force majeure by third-party transporters, or
any other cause whether of the kind herein enumerated or otherwise, not
reasonably within the control of the Party claiming force majeure.

         C.   Neither Party shall be entitled to the benefit of the
provisions of this Section 11 under either or both of the following
circumstances:

               1)   To the extent that the failure was caused by the Party
                    claiming suspension having failed to remedy the condition
                    by taking all reasonable acts, short of litigation, if
                    such remedy requires litigation, and having failed to
                    resume performance of such commitments or obligations
                    with reasonable dispatch; or,


                                       7.A

<PAGE>

              2)    If the failure was caused by lack of funds, or with respect
                    to the payment of any amount or amounts then due hereunder.

         D.   Settlement of strikes and lockouts shall be entirely within the
discretion of the Party affected, and the duty that any event of force majeure
shall be remedied with all reasonable dispatch shall not require the settlement
of strikes and lockouts by acceding to the demands of the Parties directly or
indirectly involved in such strikes or lockouts when such course is inadvisable
in the discretion of the Party having such difficulty.

         E.   If volumes of Producer's Gas are destroyed by an event of force
majeure while in Gatherer's possession, the obligations of both Parties under
this Agreement shall terminate with respect to the volumes lost but Gatherer
shall make all reasonable efforts to minimize such lost volumes.

12.      DEFAULTS

         A.   It is covenanted and agreed that if either Party shall fail to
perform any of the covenants or obligations imposed upon it under and by virtue
of the Agreement or this Appendix, in addition to its other rights and remedies,
the other Party may terminate the Agreement by proceeding as follows:

              1)    The Party not in default shall cause a written notice to
                    be served on the other Party in default, stating
                    specifically the cause for terminating the Agreement, and
                    declaring it to be the intention of the Party giving
                    notice to terminate the same; thereupon, the Party in
                    default shall have thirty (30) Days after the service of
                    the aforesaid notice in which to commence to remedy or
                    remove the cause or causes stated in the notice for
                    terminating the Agreement. If within said thirty (30)
                    Days the Party in default fails to commence the steps
                    necessary to remove and remedy said cause or causes, or
                    fully indemnifies the Party not in default for any and
                    all consequences of such breach, then such notice shall
                    be withdrawn and the Agreement shall continue in full
                    force and effect

              2)    In case the Party in default does not commence steps
                    necessary to remedy and remove the cause or causes, or
                    does not indemnify the Party giving the notice for any
                    and all consequences of such breach, within said period
                    of thirty (30) Days, then the Agreement shall become null
                    and void from and after the expiration of said period.
                    Termination of the Agreement shall not preclude the
                    non-defaulting Party from pursuing all of its rights,
                    claims and demands or other relief from the defaulting
                    Party.

         B.   No waiver by either Producer or Gatherer of any default of the
other under the Agreement shall operate as a waiver of any future default,
whether of like or different character or nature, nor shall any failure to
exercise any right hereunder be considered as a waiver of such right in the
future.

13.      UNECONOMIC WELL CONNECTIONS

         A.   In the event Gas volumes available for delivery from any group or
pod of Producer's Wells hereunder become uneconomic to Gatherer in the exercise
of Gatherer's reasonable judgment, Gatherer agrees to release from dedication to
this Agreement the affected wells and the lease(s) to the extent of the drilling
and spacing unit(s) corresponding to such wells and/or lease(s). Alternatively,
Producer may nonetheless maintain the connection to Gatherer's facilities
provided the Parties agree upon the fees for the Gatherer's services to be
provided. In setting these fees, the Parties shall take into consideration the
breakdown of fees set forth in Article IV.


14.      UNECONOMIC OPERATION OF GATHERER'S FACILITIES

         A.   If, in the opinion of Gatherer, any part of Gatherer's
Facilities is or becomes uneconomic to operate due to its volume, quality,
governmental regulation or any other cause, upon ninety (90) Days advance
written notice to Producer, Gatherer may either modify or suspend operations
thereof, in which case Gatherer shall not be obligated to take delivery of
all or any portion of the Gas from Producer's Wells, so long as such
condition exists. For the purposes hereof,

                                       8.A

<PAGE>

"UNECONOMIC OPERATION" shall be defined as circumstances under which Gatherer's
revenues from any part of Gatherer's Facilities is insufficient to offset actual
operating costs thereof.

15.      LITIGATION - ATTORNEYS' FEES

         A.   In the event litigation arising out of the Agreement should be
initiated by any Party hereto, the prevailing Party, after the entry of a final
non-appealable order, shall be entitled to recover from the other Party, as a
part of said judgment, all court costs, fees and expenses of such litigation,
including reasonable aftomeys' fees.

16.      DAMAGES

         A.   Except as otherwise provided herein, whether or not occasioned
by a default or other breach of the Agreement, neither Party shall be liable
to the other for special, exemplary, or consequential damages, except as to
third-party claims, pursuant to the indemnification provisions of the
Agreement or this Appendix.

17.      GENERAL

Gatherer in such manner as Owner, in Owner's sole discretion, may deem
advisable, including without limitation, the right, but never the obligation, to
drill new wells, to repair and rework old wells, renew or extend, in whole or in
part, any oil and gas lease covering any of the oil and gas properties, and to
abandon any well or surrender any such oil and gas lease, in whole or in part,
when no longer deemed by Owner to be capable of producing gas in paying
quantities under normal methods of operation.

                                       -4-

<PAGE>

         b.   To use gas for developing and operating Owner's oil and gas
properties committed under this Agreement and to fulfill obligations to Owner's
lessors under those properties.
         c.   To pool, combine and unitize any of Owner's oil and gas properties
with other properties in the same field, and to alter such pooling, combination,
or units, in which event this Agreement will cover Owner's allocated interest in
unitized production insofar as that interest is attributable to the oil and gas
properties committed under this Agreement, and the description of property
covered hereby shall be considered to have been amended accordingly.

                                      III.
                              POD CONNECT CRITERIA

         3.1  From and after completion of Gatherer's high pressure gathering
headers in (1) the East Dedicated Area (for gas delivered at a Point of Receipt
in the East Dedicated Area), and (ii) the West Dedicated Area (for gas delivered
at a Point of Receipt in the West Dedicated Area), at the request of Owner,
Gatherer will (in accordance with the procedures and criteria set forth in
Section 3.2 and 3.3 below) extend its System and install necessary facilities to
connect a Pod, in the event such Pod has, as reasonably determined by Gatherer,
Gas reserves dedicated to this Agreement equal to one (1) Bcf for each mile of
pipe to be laid by Gatherer from its existing System to the Point of Receipt for
such Pod.
         3.2  In order for Gatherer to determine the reserves for each Pod,
Owner will notify Gatherer in writing of Owner's desire to connect a Pod and
will furnish Gatherer with any pertinent well data (i.e.- completion reports,
logs, etc.). Within fifteen (15) days of receipt of such request (with all
supporting well data), Gatherer will notify Owner, in writing of its election
to extend its System or not to extend its System. If Gatherer elects to
extend its System and connect such Pod, Gatherer will begin the activities
necessary for such connection within ten (10) days of such election and shall
proceed with due diligence to complete such connection. If Gatherer elects
not to extend its System, Owner may lay the pipe necessary, at its sole cost
and expense, to connect such Pod to Gatherer's System and Gatherer's charges
to Owner under this Agreement shall be adjusted as set forth in Section 3.4
hereof
         3.3  If Owner does not wish to lay the pipe necessary to connect such
Pod to Gatherer's System, Owner may: (i) cause Gatherer to install the necessary
pipe by paying Gatherer, in advance, for any and all costs (as determined by
Gatherer) to connect such Pod, or (ii) request in writing that up to 1600 acres
(comprised of up to ten wells in 160-acre spacing or twenty wells in 80-acre
spacing, as the case may be) actually connected to such Pod be released from
dedication under this Agreement. Gatherer will provide such release within
thirty (30) days of Owner's written request and will have no further obligations
hereunder relative to such wells and leases so released.

<PAGE>

         3.4  In the event Gatherer has declined to make an interconnection into
its System as set forth in Section 3.2 and Owner has elected to make any such
interconnection, the fees payable under this Agreement with respect to such Gas
flowing through such interconnection shall be adjusted based on the following:
         a.   For an interconnection into Gatherer's System at any existing
Point(s) of Receipt - no change;
         b.   For an interconnection into Gatherer's System at a location
having a normal operating pressure above 25 psig but below 200 psig - the
gathering fee for such gas shall be reduced by ****** per Mcf; and
         c.   For an interconnection into Gatherer's System at a location
having a normal operating pressure at or above 200 psig - the gathering fee
for such Gas shall be reduced by ******** per Mcf.
         3.5  All interconnections made by Owner into Gatherer's System pursuant
to Section 3.2 shall be made at Owner's sole cost and expense at locations which
Gatherer reasonably determines will not adversely affect or impair operation of
Gatherer's System. In addition, Owner, at its sole cost and expense, shall cause
any such Gas connected by Owner to be delivered as follows: (i) against the
operating pressure of Gatherer's System at such location as such pressure may
exist from time to time, and (ii) with respect to Gas delivered into any segment
of Gatherer's System having a normal operating pressure at or above 200 psig, to
be dehydrated to not more than 5 pounds of water per million standard cubic feet

                                       IV.
                  CONTRACT QUANTITY, NOMINATIONS AND IMBALANCES

         4.1  Commencing with the completion of facilities for the initial
Point(s) of Receipt within the Dedicated Area and subject to the terms and
conditions of this Agreement, Gatherer shall receive from Owner all of Owner's
Gas tendered at the Point(s) of Receipt and shall redeliver Thermally Equivalent
Volumes at the Point of Delivery, less the applicable in kind Fuel reduction.
         a.   Although Gatherer agrees to employ accepted industry practices and
act as a prudent operator in the handling of Owner's Gas, the parties understand
and agree that certain volumetric gains and losses in the Gas will occur and
shall be shared by and among Owner and other third parties whose gas is gathered
on Gatherer's System, in the proportion that each party delivers Gas into
Gatherer's System at their respective Point(s) of Receipt. Gatherer will use
commercially reasonable efforts to minimize gains or losses on the System.
         b.   Gatherer shall not be obligated to receive, gather and deliver any
quantity of Gas which, when taken in addition to all other volumes of Gas which
Gatherer is obligated to gather

******        This portion of the agreement has been omitted pursuant to a
confidential treatment request that has been filed with the Securities and
Exchange Commission.

                                       -6-

<PAGE>

under any and all then existing gathering commitments, is in excess of the
design capacity or operating pressure of Gatherer's System.
         c.   Once Gatherer's System or a segment thereof is at capacity and
Owner has notified Gatherer of such constraint in writing, Gatherer shall not
enter into any new agreements which require utilization of capacity on such
segment(s) unless and until Gatherer expands its System or such segment can
accommodate additional volumes; provided, however, the parties expressly
acknowledge that this Section 4.1(c) shall not prevent Gatherer from
receiving Gas which is contracted for delivery to Gatherer's System
(including Gas produced from the drilling of additional wells) prior to such
notice.
         d.   If at any time and from time to time Gatherer is unable to gather
all of Owner's Gas from the Point(s) of Receipt for reasons other than a
violation of subparagraph (c) above, Gatherer will take Owner's Gas based on the
following priority: (i) Gatherer will take all volumes of gas on its System as
to which it has firm gathering commitments (including firm commitments to gather
Owner's Gas and gas from Gatherer's affiliates, if applicable) as a first
priority; (ii) in the event Gatherer has insufficient capacity on its System due
to an event of force majeure to satisfy all existing firm gathering commitments,
Gatherer will take all gas as to which it has such firm commitments on a
volumetrically prorated basis; and (iii) following satisfaction of all firm
gathering commitments, Gatherer will take all other gas (including Owner's Gas
and gas from Gatherer's affiliates for which no firm commitment exists) on a
volumetrically prorated basis. Prorations under the preceding sentence shall be
based on the daily nominated quantity of each source of gas up to the lower of
(A) the historical or calculated production capacity accepted by Gatherer for
such owners' interest in the wells that such owners have provided to support
their nominations, or (B) the quantity nominated for receipt under a purchase or
transportation agreement by the receiving party at the Point of Delivery, after
adjustment for Fuel. During such times Gatherer is unable to gather all of
Owner's Gas from the Point(s) of Receipt, Owner may deliver such Gas Gatherer is
unable to gather to systems other than Gatherer's System and may commit such Gas
to such other systems on a month to month basis; provided, however, once
Gatherer's System is again able to receive and deliver such volumes Gatherer
shall give written notice to Owner, whereupon Owner shall recommence deliveries
of such Gas to the System beginning on the first day of the Month immediately
following the end of thirty (30) days after Gatherer's notice. In the event
Gatherer's failure to take Owner's gas continues for sixty (60) consecutive days
(excluding the period following Gatherer's notice that it is again able to
receive and deliver volumes of Gas), except for conditions of quality or force
majeure, Owner may request (which request must be delivered, if at all, during
the continuation of such inability by Gatherer) that the volume from the
producing formations in the

                                       -7-

<PAGE>

existing wells which is in excess of the average quantity Gatherer was able
to gather during such sixty-day period be released from the dedication set
forth in Section 2.2. For example, if the average quantity of Owner's Gas
Gatherer was able to gather during such sixty-day period was 45,000 Mcfd,
then all production from the producing formations in the existing wells in
excess of 45,000 Mcfd shall be released. Upon request of Owner, Gatherer
shall release specific existing wells and the spacing units attributable
thereto which are impacted by the capacity constraint and which have a
combined production capacity (as determined at the time of Owner's request)
up to, but not to exceed, the volume released. A release under this
provision shall not apply to future wells (and the spacing units attributable
thereto) from which Gatherer is able to receive Gas at the time of drilling
and completion. Such release shall be Owner's sole and exclusive remedy for
Gatherer's failure to receive and gather any Gas dedicated hereunder for any
reason.
         4.2  Owner or Owner's designee shall provide Nominations to Gatherer as
required by Gatherer and will be responsible for all nominations and other
transportation arrangements beyond the Point of Delivery. Owner shall make or
cause its designee to make all arrangements with the downstream pipelines and
shall ensure that its desired Nominations for downstream pipeline transportation
are properly and timely placed with the downstream pipeline in accordance with
that pipeline's nomination and confirmation procedures.
         a.   For each Month during the term of this Agreement, Owner or Owner's
representatives will provide Gatherer written notice of Owner's Gas quantity
nominated for delivery at the Point(s) of Receipt and the Point of Delivery.
Owner's notice shall be based in good faith upon the producing ability of
Owner's well(s) for the upcoming Month, adjusted as necessary during the Month,
to bring cumulative receipts into line with cumulative redeliveries, and
adjusted to cover Fuel. To enable Owner to make its Nominations hereunder, prior
to initial deliveries and from time to time thereafter as reasonably deemed
necessary by Gatherer, Gatherer shall make a good faith estimate of the Fuel
(expressed as a percentage) to be consumed in operation of Gatherer's System.
Gatherer may at any time or from time to time during each Month adjust Owner's
Nomination quantity as necessary to conform to the above requirements and to
maintain balance. Except in the case of an emergency, Gatherer will notify Owner
prior to any such adjustments and shall give Owner a reasonable opportunity to
adjust its Nominations or flows and in the event Owner does not adjust its
Nominations or flows then and, in such event, Gatherer shall make such
adjustments. Gatherer shall have no obligation to accommodate any imbalances
caused by Owner's inability or failure to match Nominations with actual
performance. Complete Nomination information for the first of the Month

downstream contract number, is due to Gatherer, on a normal business day,
twenty-four (24) hours prior to the downstream pipeline's nomination deadline.
         b.   Gatherer reserves the right to adjust these deadlines
reasonably in response to changes in the practices of pipelines downstream of
the Point of Delivery.
         c.   Gatherer is not obligated to assist Owner in resolving payment or
transportation disputes with pipelines downstream of the Point of Delivery or
Owner's customers other than to confirm the volumes delivered at the Point of
Delivery for Owner's account.
         d.   Owner shall have agents or employees available at all reasonable
times to receive from Gatherer's dispatchers advice and requests for changes in
the rates of delivery of Gas as required by Gatherer due to events of force
majeure, maintenance or repair of the System or other causes affecting the
operation or integrity of the System from time to time, and Owner will modify
its deliveries accordingly.
         4.3  It is recognized that because of dispatching and other variations,
certain imbalances may occur between volumes of Gas received by Gatherer
hereunder and the volumes of Gas delivered hereunder by Gatherer. However,
Gatherer shall use reasonable efforts to deliver to or for the account of Owner
each Day at the Point of Delivery a volume of Gas equal to Owner's Nomination
quantity for such Point of Delivery. Owner shall use reasonable efforts to keep
daily and monthly deliveries of Gas into Gatherer's System equal to Owner's then
current daily and monthly Nomination quantity for the Point(s) of Receipt.
         a.   The parties agree that during the term hereof Gatherer shall have
the right and obligation to operate its Gathering System and to receive and
deliver Gas hereunder in such a way as to maintain balance on its Gathering
System as between receipt and deliveries (after adjustment for Fuel) of Gas
subject to this Agreement as closely as possible. Gatherer will have the right
to refuse to accept volumes if Owner's production exceeds its Nominations, or to
refuse Nominations if such Nominations exceed production. The parties shall
cooperate to balance Thermally Equivalent Volumes of gas as nearly as feasible
on a daily basis.
         b.   Gatherer shall keep accurate records of the quantities of gas
nominated and scheduled for gathering, which records shall be reported to Owner
on a monthly basis. If Owner's gas is commingled with other gas at the Point(s)
of Receipt or at the Point of Delivery, the scheduling arrangements and
Gatherer's records shall include the allocations made at such Point(s) of
Receipt or Point of Delivery. Allocation of volumes between producers at the
Point(s) of Receipt shall be made as requested by the operator of the wells
connected to each Pod. Allocations at the Point of Delivery shall be made as
required by the downstream transporter at the Point of Delivery, or if

                                       -9-

<PAGE>

none, by Gatherer consistent with this Agreement. In no event shall Owner be
designated the swing party for any variances at the Point of Delivery.
         c.   For each Month, in its invoice to Owner for gathering services,
Gatherer shall include a statement of actual metered volumes at the Point(s)
of Receipt and Point of Delivery, Owner's allocation of such volumes, and the
difference between the quantity of Gas allocated to Owner at the Point(s) of
Receipt, less Fuel for such Month, and the quantity of Gas credited to Owner
at the Point of Delivery (the "Imbalance Quantity"). If the quantity of gas
received by Gatherer from Owner during a Month at the Point(s) of Receipt, as
adjusted for Fuel, exceeds the quantity of gas credited to Owner at the Point
of Delivery, the imbalance shall be cashed out by the payment by Gatherer to
Owner of an amount equal to the Imbalance Quantity times the Price Index. If
the quantity of gas credited to Owner during a Month at the point of Delivery
exceeds the quantity of gas received by Gatherer from Owner during a Month,
as adjusted for Fuel, the imbalance shall be cashed out by the payment by
Owner to Gatherer of an amount equal to the Imbalance Quantity times the
Price Index.
         d.   Gatherer will attempt to enter an operational balance agreement
with respect to deliveries into FUGG, on such terms and conditions as are
reasonable, customary, and acceptable to Gatherer.

                                       V.
                    DELIVERY PRESSURE AND REDELIVERY PRESSURE

         5.1  Owner shall deliver Gas to Gatherer hereunder at pressures
sufficient to effect delivery into Gatherer's System but not to exceed the
allowable operating pressure as determined solely by Gatherer. Owner shall
install pressure limiting devices of a design satisfactory to Gatherer to insure
over pressurization shall not occur on Gatherer's System. However, Owner shall
be solely responsible for pressure protection on any facilities operated by
Owner.
         5.2  Gatherer shall install equipment that is designed to maintain a
suction pressure at the inlet flange of the first compressor at or downstream of
each Point of Receipt of 5 psig and such equipment shall have the capability to
provide a suction inlet pressure of 2 psig under certain field operating
conditions. In addition, Gatherer will endeavor (without any additional cost or
expense to Gatherer) to maintain a suction pressure of 2 psig at the inlet
flange of the first compressor at or downstream of each Point of Receipt;
provided, however, that Gatherer shall have no liability for failure to maintain
a suction pressure of 2 psig. Except for circumstances constituting an event of
force majeure, during any Month where the average daily suction pressure at the
inlet flange of any such compressor exceeds 5 psig for a period in excess of two
(2) days during such Month, the fees payable during such Month with respect to
the Pod affected by such event shall be reduced

                                       -10-

<PAGE>

by******** per Mcf for every one (1) psig that the average monthly suction
pressure exceeds 5 psig, not to exceed a maximum of ******** per Mcf.
         5.3  Except as provided in Sections 3.5 and 5.2 above, neither Owner
nor Gatherer shall be obligated to install additional equipment (or continue
operation of such equipment once installed) to effect delivery of Gas to
Gatherer hereunder, but either Gatherer or Owner shall have the right to
install and operate equipment, if required. Any equipment installed and
operated by Owner shall be at its sole cost, risk and expense and shall (i)
be prior to delivery of Gas to Gatherer's System, and (ii) not interfere with
the operation (including gas measurement) of Gatherer's System.

                                       VI.
                             MEASUREMENT AND TESTING

         6.1  The volume of Gas received by Gatherer shall be measured at the
master meters immediately downstream of each Point of Receipt. The facilities to
measure the volume and quality of Gas delivered at the Point(s) of Receipt will
be owned, maintained and operated by Gatherer.
         6.2  The volume of Gas delivered by Gatherer at the Point of Delivery
shall be metered through a meter caused to be located by Gatherer at the Point
of Delivery.
         6.3  In the event that at any time, or from time to time, Gatherer
commingles Gas from Point(s) of Receipt with Gas from other than the Point(s) of
Receipt hereunder, Gatherer agrees to measure such other gas prior to its
entering Gatherer's System.
         6.4  The unit of measurement for Gas hereunder shall be one (1) cubic
foot of gas, and the term "cubic foot of gas" wherever used herein shall mean a
cubic foot of Gas at a temperature of sixty degrees Fahrenheit (60DEGF) and at a
pressure of fourteen and seventy-three hundredths (14.73) Psia.
         6.5  The Gas shall be metered downstream of the Point(s) of Receipt by
orifice meters which shall be constructed and installed in accordance with the
applicable provisions of the then current American Gas Association's Gas
Measurement Committee Report No. 3, as amended. Subject to the receipt of any
necessary governmental or regulatory approvals and authorizations, electronic
flow measurement recording devices (EFM) shall be installed at each of
Gatherer's master meters at the Points of Receipt. The volumes of Gas received
and delivered by Gatherer as measured at pipeline pressures and temperatures
shall be computed from the meter records and converted into the unit of
measurement specified above in accordance with the methods prescribed in the
then current Gas Measurement Committee Report No. 3 of the American Gas
Association, including the appendix thereto. Correction shall be made for
deviation from the Ideal Gas Laws at the pressure and temperature at which the
Gas is metered. To determine the factors for such correction a quantitative
analysis of the Gas shall be made at reasonable intervals, and such factors
shall be

obtained from data contained in the then current "Super-Compressibility
Factors for Natural Gas", Volumes 1 through 6, inclusive, or in "Tables for
the Determination of Super-Compressibility Factors for Natural Gas Containing
Nitrogen and/or Carbon Dioxide", Volume 7, as published by the American Gas
Association, or any subsequent revision thereof For the purposes of
measurement and meter calibration, the atmospheric pressure shall be assumed
to be twelve and seven-tenths (12.7) pounds per square inch, without regard
to variations in natural atmospheric pressure from time to time. Each EFM
unit will be equipped with communication equipment and Gatherer shall allow
Owner (or Owner's designee) remote electronic access to Gatherer's EFM data
for each master meter measuring gas from Owner hereunder. In the event
Gatherer has access to EFM data for deliveries into FUGG, Gatherer shall,
upon Owner's request, provide such EFM data with respect to Owner's volumes
of gas delivered into FUGG.
         6.6  The specific gravity of the Gas flowing through meters downstream
of the Point(s) of Receipt shall be determined by Gatherer at such intervals as
may be practicable under the circumstances, but at least semi-annually. All such
determinations of specific gravity shall be made by a standard gravity balance
in accordance with the provisions of the Natural Gas Processors Association
Publication No. 3130, entitled "Standard Method for Determining the Specific
Gravity of Gas", or by a gravitometer employing the "Momentum Method" of
specific gravity determinations as described in Chapter VII, "Determination of
Specific Gravity", of the then current American Gas Association Gas Measurement
Manual; or by standard calculation method using aforementioned Gas sample. The
specific gravity of the Gas flowing through each meter determined by either of
the above-mentioned methods shall be used in computing the volume of Gas
delivered through such meter. The specific gravity determined by any test shall
apply from the date the test was taken until the date of the next test.
         6.7  Temperature of the Gas gathered hereunder shall be determined by a
recording thermometer to record the temperature of the Gas flowing through each
meter, and the arithmetic average of the hourly temperatures recorded shall be
used in correcting the volumes delivered hereunder to the unit of measurement
specified above.
         6.8  The accuracy of Gatherer's measuring equipment shall be
verified by test, using means and methods generally acceptable in the gas
industry, at least semi-annually. Notice of the time and nature of each test
shall be given by Gatherer to Owner sufficiently in advance to pen-nit
convenient arrangement for Owner s representative to be present. Measuring
equipment found to be registering inaccurately shall be adjusted to read as
accurately as possible. If, after notice, Owner fails to have a
representative present, the results of the test shall nevertheless be
considered accurate until the next test. Gatherer shall, upon written request
by Owner, conduct a test of Gatherer's

                                       -12-

<PAGE>

measuring equipment, provided that in no event shall Gatherer be required to
test its equipment more frequently than once a month. All tests of such
measuring equipment shall be made at Gatherer's expense, except that Owner
shall bear the expense of tests made at its request if the inaccuracy is
found to be two percent (2%) or less.
         6.9  If for any reason any measuring equipment is inoperative or
inaccurate so that the volume of Gas delivered is not correctly indicated by
the reading thereof and, if such reading is in error by more than two percent
(2%) in the measurement of Gas, then the volume of Gas delivered, during the
period such measuring equipment is inoperative or inaccurate, shall be
determined by the parties hereto on the basis of the best data available
using the first of the following methods which is feasible:
         (i)   By using the registration of any check measuring equipment
               installed and accurately registering;
         (ii)  By correcting the error if the percentage of error is
               ascertainable by calibration, test or mathematical
               calculations; or
         (iii) By comparing deliveries made during preceding periods
               under similar delivery conditions when the meter was
               registering accurately.
         An adjustment based on such determination shall be made for such period
of inaccuracy as may be definitely known, or if not known, then for the lesser
of (i) one-half the period since the date of the last meter test or (ii) three
Months.
         6.10 Gatherer and Owner shall have the right to inspect equipment
installed or furnished by the other party, and the charts and other measurement
or test data of the other party, at all times during business hours; but the
reading, calibration and adjustment of such equipment and changing of charts
shall be done by the party installing and furnishing same. Unless the parties
otherwise agree, each party shall preserve all original test data, charts and
other similar records in such party's possession for a period of at least two
(2) years.
         6.11 In the event new technologies are developed and adopted by the
natural gas industry with respect to the measurement of volumes or determination
of gross heating value, Gatherer shall employ such technologies in connection
with operation of the System to the extent such technologies are economically
justified for the System, as determined by Gatherer acting in its reasonable
judgment.

                                      VII.
                             QUALITY SPECIFICATIONS

         Gas delivered by Owner hereunder shall be merchantable Gas conforming
to the following specifications:

                                       -13-

<PAGE>

         7.1  HEATING QUALITY, SULPHUR, CARBON DIOXIDE, OXYGEN, AND NITROGEN.
Gatherer may refuse to receive Gas with a Gross Heating Value of less than nine
hundred and fifty (950) Btu's. The Gas shall not contain any of the following in
excess of: one quarter (1/4) grain of hydrogen sulphide per hundred (100) cubic
feet; twenty (20) grains of total sulphur per hundred (100) cubic feet; four
percent (4.0%) by volume of carbon dioxide; ten parts per million (10 ppm) by
volume of oxygen; or three percent (3.0%) by volume of Nitrogen. Owner shall
make reasonable efforts to keep the Gas entirely free of oxygen.
         7.2  TEMPERATURE. The temperature of the Gas at the Point(s) of Receipt
shall not be in excess of one hundred twenty degrees (120DEG) Fahrenheit.
         7.3  WATER AND HYDROCARBON DEW POINT. Owner agrees that at the
temperature and pressure Gas is delivered hereunder it shall not contain any
hydrocarbon or non-hydrocarbon fractions which would condense to free liquids in
the pipeline at the operating pressure of Gatherer's System. The Gas shall not
contain any free H2O in the liquid state. Gatherer shall be responsible for any
additional dehydration required to meet any differing quality specifications of
downstream pipelines.
         7.4  MISCELLANEOUS. The Gas shall be commercially free of solids, sand,
dust, gums, crude oil, water and hydrocarbons in the liquid phase, and other
objectionable substances which may be injurious to pipelines or which may
interfere with the transmission or commercial utilization of said Gas.
         7.5  QUALITY GUIDELINES. Notwithstanding the above all Gas delivered
hereunder shall conform to the then current quality specifications, standards
and/or tariff requirements of any downstream pipeline for heating quality,
sulphur, carbon dioxide, oxygen and nitrogen (or any other quality
specifications not covered in this Agreement that are specified in such
downstream pipeline's then current tariff), subject, however, to the following
exceptions: Gatherer will accept gas for delivery on its System (A) with Gross
Heating Value less than the specification contained in this Agreement or the
specification of any applicable downstream pipeline or (B) a nitrogen content in
excess of the specification contained in this Agreement or the specification of
any downstream pipeline to the extent, and only to the extent, with respect to
either event in clause (A) and (B) such downstream pipeline accepts such gas. In
the event any downstream pipeline refuses to accept Owner's gas for failure to
meet the specifications in clause (ii) above, then Gatherer may, at its option,
reject such gas under this Agreement. In addition, should Owner's gas have a
carbon dioxide content (as measured at any Point of Receipt) in excess of four
percent (4%), Gatherer shall accept such gas to the extent, and only to the
extent, (i) such gas, when commingled with other streams of gas, is in
compliance with such specification, and (ii) Gatherer determines, acting in its
sole

                                       -14-

<PAGE>

discretion, that a carbon dioxide content in excess of four percent (4%) is
not detrimental to its System (or any part thereof).
         7.6  TESTS. Tests to determine the total sulphur, hydrogen sulphide,
carbon dioxide, oxygen and water vapor content of the Gas at the Point(s) of
Receipt shall be made by Gatherer by approved standard methods in general use in
the gas industry. Such tests shall be scheduled and made at the same time as are
the meter tests provided for in Article VI hereof, or as frequently as deemed
necessary by Gatherer.
         7.7  SUB-QUALITY GAS. Whenever the quality of the Gas delivered by
Owner hereunder does not conform to the quality specifications contained
herein, Gatherer shall have the night, upon notice to Owner, to: (i)
discontinue or cur-tail Gatherer's receipt of Owner's Gas hereunder, or (ii)
condition such off specification Gas and charge Owner a competitive rate for
such conditioning; provided, however, that Gatherer shall not unduly
discriminate against Owner with respect to curtailment or conditioning as
compared to other parties on Gatherer's System which are similarly situated
on the same segment of Gatherer's System. In the event Gatherer elects not to
condition Owner's Gas or in the event the rate at which Gatherer proposes to
condition such Gas is not competitive then, and in either such event, Owner
shall have the option to condition such Gas to make it conform to the quality
specifications of this Agreement; provided, however, if Owner elects to
condition its Gas, nothing contained in this Agreement shall obligate
Gatherer to pay for any such conditioning.
         If neither Gatherer nor Owner treats Gas produced from a well(s) which
does not conform to the quality specifications of this Agreement and Gatherer
chooses not to accept such Gas, then at the written request of Owner, Gatherer
shall release from the provisions of this Agreement up to 1600 acres (comprised
of up to ten wells on 160-acre spacing or twenty wells on 80-acre spacing, as
the case may be) actually connected to the Pod which is producing off
specification Gas.

                                      VIII.
                                     CHARGES

         8.1 Subject to the provisions hereof, for each Point of Receipt
hereunder Owner shall pay Gatherer as follows:
         (i)   For Gas delivered by Owner to Gatherer at
               Point(s) of Receipt located in the East Dedicated Area, Owner
               shall pay Gatherer ******** per Mcf of Owner's Gas received.
         (ii)  For Gas delivered by Owner to Gatherer at Point(s) of
               Receipt located in the West Dedicated Area, Owner shall pay
               Gatherer ******** per Mcf of Owner's Gas received.

<PAGE>

         8.2  The rates set forth in Section 8.1 (as adjusted for reductions,
if any, pursuant to Section 3.4) above shall be adjusted commencing on the
first day of the Month following the first anniversary of the date of first
deliveries of Owner's Gas into Gatherer's System, and annually thereafter, by
multiplying the applicable gathering fee then in effect by a fraction, the
numerator of which is the CPI Index for January of the year in which such
calculation is made, and the denominator of which is the CPI Index for
January of the immediately preceding year. "CPI Index" shall mean the
Consumer Price Index for All Urban Consumers ("CPl-U") as published for such
Month by the U.S. Department of Labor.  In no event shall the gathering fees
due hereunder ever be less than the rate(s) set forth in Section 8. 1.
         8.3  Notwithstanding the terms of Section 8.1 above, in the event
Gatherer provides gathering service on the System to a third party pursuant to
an agreement with a primary term exceeding fifteen (1 5) years at rates for
"Comparable Service" (as hereafter defined), lower than those set forth in this
Agreement, then Owner's rates herein shall automatically be adjusted as follows:
all rates otherwise payable by Owner under this Agreement for service in the
applicable portion of the Dedicated Area (i.e. the East Dedicated Area or the
West Dedicated Area, as applicable) shall be multiplied times a fraction, the
numerator of which is the rate charged to such third party for Comparable
Service and the denominator of which is the rate charged to Owner under this
Agreement for such service. For purposes of this Section 8.3, "Comparable
Service" shall mean gathering service provided to third parties in the same
portion of the Dedicated Area (i.e. the East Dedicated Area or the West
Dedicated Area) and at interconnections into Gatherer's System within the same
parameters set forth in Section 3.4. For example, in the event Gatherer extends
gathering service for receipt into Gatherer's System in the East Dedicated Area
under the parameters set forth in Section 3.4(a) at a rate of *********, then
all rates payable by Owner for service in the East Dedicated Area shall be multi
lied by the fraction ******** and rates in the West Dedicated Area would not be
reduced. As a second example, in the event Gatherer extends gathering service
for receipt into Gatherer's System in the East Dedicated Area under the
parameters set forth in Section 3.4(b) at a rate of ********, then all rates
payable by Owner for service in the East Dedicated Area shall be multiplied by
the fraction ******** and rates in the West Dedicated Area would not be reduced.
Rates payable by Owner for service in the East Dedicated Area or the West
Dedicated Area, as applicable, shall not be reduced unless Gatherer has given a
lower rate to the third party for service in such area.
         8.4  Owner shall have the option, to be exercised in writing no later
than thirty (30) days prior to the end of each Contract Year to convert to firm
service a portion of the gathering service to be rendered under this Agreement
(such election to be effective on the first day of a Month

specified in Owner's notice during the immediately succeeding Contract Year).
For such firm service, Owner shall pay Gatherer, in lieu of the charges per
Mcf set forth in Section 8.1, an advance monthly demand charge equal to the
applicable per unit charge in Section 8.1 multiplied by a quantity determined
in this Section 8.4. Owner may exercise its option to convert to firm service
for a quantity of up to fifty percent (50%) of Owner's average monthly usage
of gathering services hereunder for the Contract Year during which Owner's
notice is delivered; provided, however, that Owner's election to convert to
firm service shall not be cumulative from one Contract Year to the next and
Owner may not reduce its commitment for firm service from one Contract Year
to the next; and, further provided, in no event shall Owner ever be entitled
to firm gathering service during any given Month or on any given Day, as
applicable, for a quantity in excess of 900,000 Mcf/Month or 30,000 Mcf/Day.
Notwithstanding the other terms of this Section 8.4, Owner shall not be
entitled to (and Gatherer shall not be obligated to provide) firm gathering
service at any time from and after January 1, 2010. Gatherer's receipts from
Owner shall be allocated first to Owner's firm gathering service and then to
its pro rata service under this Agreement.

                                       IX.
                         BILLING, PAYMENT AND REPORTING

         9.1  On or before the twentieth (20th) day of each Month after
deliveries of Gas commence hereunder, Gatherer shall render to Owner or Owner's
representative a statement for the preceding Month identified as to the Point(s)
of Receipt and Point of Delivery, showing the daily and total volumes of Gas
allocated to delivery hereunder, the amount due therefore and information
sufficient to explain and support any adjustments in volumes or amounts made by
Gatherer in determining the amount billed. The Owner or Owner's representative
shall pay Gatherer at the address shown hereunder on or before the last day of
each Month, or if the statement is rendered by Gatherer after the twentieth
(20th) day, within ten (10) days after receipt of such statement. If the correct
amount is not paid when due, interest on any unpaid portion of the correct
amount shall accrue at the lesser of: (i) the highest rate of interest permitted
by applicable law, or (ii) fifteen percent (15%) per annum. If any default
continues after thirty (30) days' written notice from Gatherer to Owner,
Gatherer may suspend receipt of Gas hereunder without prejudice to any other
available remedies at law or in equity.
         9.2  If any overcharge or undercharge in any form whatsoever shall at
any time be found and the bill therefore has been paid, Gatherer shall refund
any amount of overcharge, and Owner shall pay any amount of undercharge within
thirty (30) days after final determination thereof, provided that no retroactive
adjustment will be made beyond a period of two (2) years from the date a
discrepancy occurs.

                                       -17-

<PAGE>

         9.3  Both parties hereto shall have the night at any and all reasonable
times to examine the books and records of the other party to the extent
necessary to verify the accuracy of any statement or charge, computation, or
demand made pursuant to this Agreement.

                                       X.
                                      TAXES

         Owner agrees to reimburse Gatherer upon invoice for the full amount
of any taxes or charges (of every kind and character except corporate
franchise and excess profits taxes and taxes measured by net income) levied,
assessed or fixed by any municipal or governmental authority against Gatherer
or its business in connection with or attributable to the volumes, value or
gross receipts from the gathering of the Gas received from Owner hereunder or
against such Gas itself or the act, right or privilege of ownership,
production, severance, handling, transmission, compression, treating,
distribution, sale delivery or redelivery of such Gas, whether such tax or
charge is based upon the volume, value or gross receipts from the gathering
of such Gas or upon some other basis.

                                       XI.
                          CONTROL, POSSESSION AND TITLE

         11.1 Gatherer shall have no responsibility with respect to the Gas or
on account of anything which may be done, happen or arise, with respect thereto,
until the Gas is delivered into Gatherer's System at the Point(s) of Receipt
provided herein. Owner shall have no responsibility with respect to the Gas or
on account of anything which may be done, happen or arise, with respect thereto
after receipt thereof by Gatherer and prior to delivery thereof at the Point of
Delivery. After the delivery of Gas at the Point of Delivery, Gatherer shall
have no responsibility with respect to such Gas or on account of anything which
may be done, happen or arise with respect thereto.
         11.2 Owner represents and warrants to Gatherer that all Gas which Owner
causes to be delivered to Gatherer shall not have previously been transported in
interstate commerce or otherwise cause Gatherer's facilities to be subject to
jurisdiction of any regulatory authority.
         11.3 Owner warrants title to or the right to deliver all Gas delivered
hereunder, that it has the right to deliver same hereunder and that such Gas is
free from liens and adverse claims of every kind, and each agrees to indemnify
Gatherer from all suits, actions, debts, accounts, damages, costs, losses and
expenses arising from or out of adverse claims of any or all persons, including
governmental entities, as to said Gas or as to royalties or charges thereon or
as to the construction and/or operation of any facilities related to service
hereunder. Title to the Gas delivered or caused to be delivered by Owner to
Gatherer hereunder at the Point(s) of Receipt shall remain with Owner and shall
not pass to, nor vest in, Gatherer. The foregoing indemnity shall apply as to
any adverse claims concerning the ownership of coalbed methane as between the
coal estate and the oil and gas

                                       -18-

estate but any such adverse claim shall not constitute a breach by Owner of
the warranty of title except to the extent of any deliveries by Owner
following an adverse and final, nonappealable court order.
         11.4 Each party agrees to indemnify and hold the other party harmless
from and against any and all suits, actions, damages, costs, losses and expenses
sustained by such other party relative to any breach by either party of the
covenants herein expressed.
         11.5 Gatherer will endeavor to keep its System clear of hydrocarbon
liquids and other obstructions. In consideration of such obligation, Owner
hereby conveys to Gatherer all right, title and interest in and to any
condensate attributable to Owner's gas which Gatherer may collect from the
System. Owner's initial production into the System shall consist solely of
natural gas produced from coalbed methane formations - for such production,
Owner and Gatherer believe that all liquid hydrocarbons, if any, shall remain
entrained in the natural gas stream and redelivered to Owner at the Point of
Delivery. It is possible that conventional natural gas production will be
delivered by Owner into the System the future - in such event (and to the extent
Gatherer collects condensate on its System which is attributable to Owner's
gas), Gatherer shall distribute to Owner a portion of the proceeds from any
sales of such condensate, calculated as follows: (i) the royalty percentage for
owner's Leases, times (ii) the total proceeds from such condensate sales
(propane and heavier only), times (iii) a fraction, the numerator of which is
the total theoretical hydrocarbon content (propane and heavier) attributable to
Owner's gas for the Month immediately prior to such sales and the denominator of
which is the total theoretical hydrocarbon content (propane and heavier)
attributable to all gas delivered to the System for such Month

                                      XII.
                                  FORCE MAJEURE

         12.1 In the event of either party hereto being rendered unable, wholly
or in part, by force majeure, to carry out its obligations under this Agreement,
then the obligations of the party experiencing such event of force majeure,
except for payment due, so far as they are affected by such force majeure, shall
be suspended during the continuance of any inability so caused, but for no
longer period, and such cause shall, to the extent possible, be remedied with
all reasonable dispatch. The party claiming force majeure shall give notice and
reasonable particulars thereof to the other party as soon as is reasonably
practicable and shall remedy the force majeure with reasonable diligence.
         12.2 The term "force majeure" as employed herein shall mean acts of
God, strikes, lockouts or other industrial disturbances, acts of the public
enemy, wars, blockades, military action, insurrections, riots, epidemics,
landslides, lightning, earthquakes, fires, storms or storm warnings,

                                       -19-

crevasses, floods, washouts, arrests and restraints of government and people,
civil disturbances, explosions, breakage or accident to machinery or lines of
pipe, the necessity for testing or making repairs or alterations to machinery
or lines of pipe, freezing of well(s) or lines of pipe, failure of third
party transporters, inability to obtain easements and/or rights-of-way,
inability of any party hereto to obtain necessary materials, supplies or
pen-nits due to existing or future rules, regulations, orders, laws or
proclamations of governmental authorities (both Federal and State), including
both civil and military, and any other causes, whether of the kind herein
enumerated or otherwise, and whether caused or occasioned by or happening on
account of the act or omission of one of the parties hereto or some persons
or concern not a party hereto, not within the control of the party claiming
suspension, and which by the exercise of due diligence such party is unable
to prevent or overcome.
         12.3 It is understood and agreed that the settlement of strikes or
lockouts shall be entirely within the discretion of the party having the
difficulty, and that the above requirement that any force majeure shall be
remedied with all reasonable dispatch shall not require the settlement of
strikes or lockouts by acceding to the demands of the opposing party when such
course is inadvisable in the discretion of the party having the difficulty.

                                      XIII.
                                      TERM

hereunder unless, and until, the assignee has delivered a ratification of this
Agreement as to the interest assigned. No transfer of, or succession to the
interest of any party hereto, wholly or partially, shall affect or bind any
other party until the other party shall have received written notice of such
transfer.

parties in identification of the provisions hereof and shall not constitute a
part of the Agreement nor be considered in the interpretation of this Agreement.
         15.3 Failure to exercise any right or rights hereunder shall not be
considered a waiver of such right or rights at the time or in the future for
like failure to assert rights.
         15.4 The language of this Agreement shall not be construed in favor of
or against either Gatherer or Owner, but shall be construed as if the language
were mutually drafted by both parties. This Agreement constitutes the entire
understanding of the parties relating to the gathering of Gas and is intended to
be the final, exclusive and complete expression of their agreement and its
terms. No other representations, understandings, or agreements have been made or

         15.7 This Agreement may be executed in any number of counterparts, no
one of which need be executed by all parties, or may be ratified, adopted, or
consented to by separate instrument in writing specifically referring hereto,
and it shall be binding upon all parties who execute a counterpart,
ratification, adoption, or consent with the same force and effect, and to the
same extent as if all such parties had executed and signed the same document,
with each separate counterpart, ratification, adoption, or consent deemed to be

by order, rule or regulation, as appropriate, of any court or governmental
authority of competent jurisdiction, to contravene, or to be invalid under,
the laws of any political body having jurisdiction over the subject matter
hereof, then such contravention or invalidity shall not invalidate the entire
Agreement. Instead this Agreement shall be construed as if it did not contain
the particular provision or provisions, or portion thereof, held to be
invalid, and the rights and obligations of the parties shall be construed and
enforced accordingly, and thereupon this Agreement shall remain in full force
and effect.
         15.9 NEITHER PARTY SHALL BE LIABLE OR OTHERWISE RESPONSIBLE TO THE

the Agreement in strict confidence, and that it shall not cause or permit

(ii) is required to disclose same pursuant to applicable law, including without
limitation, filings with applicable securities regulators; (iii) is required to

         combustion are cooled to the initial temperature of the gas and air and
         when the water formed by combustion is condensed to the liquid state.

                  LOSSES. Any loss, cost, expense, liability, damage, demand,
         suit, claim, sanction, settlement, judgment, lien, fine, penalty, and
         interest of every kind and character (including reasonable fees and
         expenses of attorneys).

                  PURCHASING FACILITIES. Any facility, including but not limited
         to dehydration, pigging equipment, pipelines and compressors, acquired
         hereby or contemplated hereunder. to be installed, operated and/or
         maintained by Buyer regardless of whether Buyer owns, operates, leases
         or contracts for any such facilities, including facilities installed,
         owned and operated by MIGC, Inc.

                  LANDS. The lands described on Exhibit A in which Seller owns
         leasehold interests, described on Exhibit A, attached hereto and made a
         part hereof, together with any wells in which Seller owns interests
         which are now or hereafter drilled on the lands.

         2.       TERMS OF PURCHASE AND SALE.

         2.1      DELIVERY.

         a.       Seller shall deliver gas to Buyer at the Delivery Point(s)
         against the operating pressures at the Delivery Point(s) as they from
         time to time exist; provided, Buyer agrees that it shall not cause the
         Delivery Point to be operated at an average pressure exceeding 100
         psig. If the average pressure at the Delivery Point exceeds 100 psig in
         any Accounting Period, then upon written notice by Seller of such
         noncompliance, Buyer shall have sixty (60) days to remedy that
         non-compliance. If Buyer fails to remedy the non-compliance within
         sixty (60) days of such notice, then upon written request from Seller,
         the capacity commitment in 2.2(b) below shall be reduced to that
         quantity of gas that Buyer can accept within compliance and Seller's
         interest in all additional. production from the Lands committed
         pursuant to 2.2(a), below, shall automatically be permanently released
         from this Agreement. Furthermore, upon written request of Seller, Buyer
         shall reduce the acreage commitment under 2.2(a), below, to those wells
         and leases attributable thereto that are sufficient to meet the
         capacity commitment on the date of that release.

         b.       The Buyer and Seller are also parties to the Gas Sales
         Agreement, referred to below. In order to provide for coordinated
         nominations and balancing procedures under both this Agreement and
         under the Gas Sales Agreement, the parties are entering into the
         Nomination and Balancing Agreement of even date herewith; which shall
         be applicable to deliveries and receipts under this Agreement as well
         as under the Gas Sales Agreement.

         2.2      COMMITMENT AND QUANTITY.

         a.       Seller hereby commits, sells, and agrees to deliver to Buyer;
         and Buyer agrees to purchase and receive, or cause to be received for
         Buyer's account, from Seller, all gas attributable to the leasehold
         interests of Seller and produced from formations from the surface of
         the earth to the base of the Tertiary Age Coal Formations from wells
         now or hereafter located on the Lands, up to the lesser of (i) the then
         applicable Contract Capacity, or (ii) a quantity of gas equal to the
         quantity repurchased by Seller under the Gas Sales Agreement between
         the Pates of even date herewith (the "Gas Sales Agreement") plus
         Retained Fuel, as defined in the Gas Sales Agreement. Seller agrees
         that the foregoing dedication shall be a covenant running with the land
         and that any assignment, sale or other transfer of all or a portion of
         Seller's interests in the Lands shall include and be subject to the
         dedication under this Agreement. It is recognized that because of
         dispatching and other variations, certain differences may occur between
         the quantity of gas delivered to Buyer under this Agreement (net of
         Retained Fuel) and the quantity of gas delivered by Buyer to Seller
         under the Gas Sales Agreement. The provisions of Paragraph 6 of that
         certain Gas Nominations and Balancing Agreement entered into between
         the parties of even date herewith shall apply to the resolution of such
         differences.

         b.       Buyer agrees to initially provide a Contract Capacity of
         11,000 Mcf per Day. Buyer will use reasonable efforts to make that
         Contract Capacity available on or before April 1, 1999, but shall not
         have any liability to Seller for any failure to provide that Contract
         Capacity before that date.

         c.       From and after April 1, 1999, if Buyer, for reasons other than
         force majeure conditions, during any 3 consecutive Accounting Periods,
         fails to receive an average daily quantity of Seller's gas of at least
         95% of the lesser of (i) the then applicable Contract Capacity or (ii)
         the average quantity of gas actually made available for delivery by
         Seller (such amount being referred to as the "Required Volume), then
         Buyer shall be deemed deficient in its receipts by an amount equal to
         the difference between the Required Volume and the actual average
         receipts during those 3 consecutive Accounting Periods ("Deficient
         Quantity"). Seller shall have the right to request a permanent release
         of the Deficient Quantity by requesting such in writing to Buyer within
         15 days following the end of the applicable 3 Accounting Periods.
         Following that timely request, Buyer shall have 30 days ("Cure Period")
         in which to begin receiving the Required Volume, or if such cannot be
         remedied within the Cure Period, to nevertheless provide a reasonable
         plan to Seller specifying the actions that will be undertaken by Buyer
         to remedy the failure to purchase and receive the Required Volume. If
         Buyer does neither, then at the end of the Cure Period, the Deficient
         Quantity shall be automatically and permanently released from the terms
         of this Agreement. Upon that release the Contract Capacity shall be
         reduced by an amount equal to the Deficient Quantity and the Minimum
         Quantity under Section 2.3, b., shall also be reduced by an amount
         equal to the Deficient Quantity.

         d.       If Seller has Excess Gas at any Delivery Point, Seller may
         request Buyer, in writing, to cause the expansion of the Purchasing
         Facilities to increase the Contract Capacity to

                                       3

<PAGE>

         accommodate the delivery of that Excess Gas. Buyer will then have
         thirty (30) days after such request to determine whether it is economic
         for Buyer, in Buyer's sole judgment, to cause the expansion of the
         Purchasing Facilities under the terms of this Agreement, considering
         the amount of additional gas available from Seller and all other
         physical and economic conditions then existing. In the event that Buyer
         determines that it is economic for Buyer to cause the expansion of the
         Purchasing Facilities under the terms of this Agreement, Buyer shall
         cause the expansion of the Purchasing Facilities under the terms of
         this Agreement in a timely and diligent fashion, provided however,
         Buyer shall not be obligated to cause any expansion prior to date that
         Fort Union Gas Gathering L.L.C.'s header system is fully operational.
         Upon that expansion, the Contract Capacity shall be deemed increased by
         the amount of additional capacity provided by the expansion that is
         necessary to accommodate the Excess Gas; and, upon that expansion, the
         Excess Gas shall not be considered Excess Gas but shall be gas
         comprising the Required Volume under c., above.

         e.       In the event that Buyer determines that the additional
         capacity requested under paragraph d., above is uneconomic in Buyer's
         sole judgement, then the Excess Gas shall be permanently released from
         the terms of this Agreement upon the request of Seller.

         f.       During periods when gas production from all wells (including
         the wells on the Lands hereunder and wells of third party sellers)
         delivering to a Delivery Point exceeds the capacity available at that
         Delivery Point, Buyer shall curtail receipts of all Excess Gas, on a
         ratable basis pursuant to the-capacity committed to all sellers
         connected to the Delivery Point. Buyer shall not enter into commitments
         to provide service to producers, including Seller, in excess of the
         total capacity of the Purchasing Facilities, as it from time to time
         exists.

         g.       During periods when gas production from all wells connected to
         all Purchasing Facilities (including the Wells hereunder and wells of
         third party sellers) exceeds the capacity available to Buyer from third
         parties to receive, transport, redeliver and/or sell gas, then Buyer
         shall take gas ratably from all sources upstream of the capacity
         restriction. Gas shall be curtailed ratably from wells producing gas
         not in association with oil first and then, if capacity is still
         restricted, gas shall be curtailed ratably from wells producing gas
         together with oil ("Associated Gas"). With respect to Seller's gas that
         Buyer transports in the facilities of MIGC, Inc., Buyer agrees that
         receipts of Seller's gas shall not be curtailed due to curtailments by
         MIGC unless MIGC is then curtailing all firm transportation service.

         2.3      Price and Fees.

         a.       Buyer shall pay Seller for Seller's gas delivered to the
         Delivery Point(s) hereunder, less Retained Fuel, as defined in the Gas
         Sales Agreement. It is understood that no compensation is due from
         Buyer, or any other party, for Retained Fuel. Buyer use reasonable
         efforts to minimize fuel use and shall cause its transporters to do the
         same. Further, the gas to be resold to Seller under the Gas Sales
         Agreement, shall include any gain or loss from the Delivery Point
         through the discharge of all Purchasing Facilities where Seller's gas
         is compressed.

                                       4

<PAGE>

         b.       The Purchase Price for Seller's gas, less Retained Fuel, shall
         be equal to (i) the quantity of Seller's gas delivered to Buyer, at the
         Delivery Point, less Retained Fuel, in MMBtu, multiplied by the Index,
         less (ii) the Contract Volume (as defined below) of Seller's gas, in
         MCF, multiplied by a Fee. The Fee shall be ********* per MCF. "Index"
         shall be equal to the "INSIDE FERCs GAS MARKET REPORT, Prices of Spot
         Gas Delivered to Pipelines" index for Colorado Interstate Gas Company,
         Rocky Mountains, in the first publication of the applicable month.
         Should the above index not be published, the parties shall mutually
         agree as to an alternative publication with a price representative of
         the foregoing. "Contract Volume" shall be the greater of (i) the actual
         quantity of gas delivered; or, (ii) 95% of the Minimum Quantity; in
         MCF. During the first two Accounting Periods following the date of
         initial deliveries, the Minimum Quantity shall be five thousand (5,000)
         MCF per day. For the next thirty six (36) Accounting Periods, the
         Minimum Quantity shall be eleven thousand (11,000) MCF per day.
         Thereafter, the Minimum Quantity shall be zero. If Buyer fails to
         accept the Minimum Quantity for any reason other than due to Seller's
         inability or failure to deliver same, the Minimum Quantity for the
         Accounting Period in which the failure occurred shall be adjusted
         downward by the quantity that Buyer failed to accept. If Seller is
         unable or fails to deliver the Minimum Quantity, then, if Buyer
         purchases and receives third party gas to replace Seller's unused
         capacity, the Minimum Quantity shall be adjusted downward by the
         quantity of such third party gas.

         c.       The applicable Fee specified in 2.3, b. (ii)., above, shall be
         adjusted on an annual basis (beginning on the first day of the second
         year of the Primary Term) in proportion to the percentage change, from
         the preceding year, in the Producer Price Index for oil and gas field
         services (SIC 138) as published by the Department of Labor. The
         adjustment of the applicable portion of the fees shall be made
         effective upon each anniversary of initial deliveries hereunder and
         shall reflect the percentage change in the foregoing index as it
         existed for the immediately preceding January from the index for the
         second immediately preceding January.

         3.       TERM.

         3.1      The term of this Agreement shall extend, subject to 3.2,
below, for a period of ten (10) years from the Effective Date, ("the Primary
Term") and month-to-month thereafter until canceled by either Party upon 30
days prior written notice in advance of the expiration of the Primary Term or
of any monthly extension thereof.

         3.2      If Buyer determines, in good faith, that it is uneconomic
for Buyer to continue to receive and purchase Seller's Gas, at any Delivery
Point(s), then Buyer shall have the right to give Seller written notice of
that condition ("Uneconomic Notice"). Upon that notice:

         a.       The parties shall then attempt in good faith to negotiate
         mutually acceptable terms to provide for continued delivery of gas at
         the affected Delivery Point(s).

******        This portion of the agreement has been omitted pursuant to a
confidential treatment request that has been filed with the Securities and
Exchange Commission.

                                       5

<PAGE>

         b.       If the parties cannot agree on those terms within 60 days
         following the date of the Uneconomic Notice, then Buyer shall have the
         right to terminate this Agreement upon 10 days' written notice.

         c.       As used herein, "uneconomic" means circumstances under which
         the Fee attributable to the gas delivered at affected Delivery Point(s)
         is insufficient to offset Buyer's actual costs of performing under this
         Agreement and under the Gas Sales Agreement with respect to that gas.

         4.       MEASUREMENT. Measurement and determination of gas delivered,
including quantity and Gross Heating Value, shall be calculated by Buyer from
the measurements taken at the meter installed, operated and maintained by Buyer
at the Delivery Point, and from the Gross Heating Value determined by gas
chromatography, all in accordance with the recommendations set forth in the AGA
Measurement Committee Report Number 3, including any amendments or superseding
standards agreeable to the parties. The unit of measurement shall be one million
British Thermal Units (MMBtu). The measurement provisions in Exhibit C shall be
applicable to this Agreement.

         5.       QUALITY. In the event that any gas delivered by Seller
fails to meet any of the quality specifications set forth on Exhibit B, then
Buyer shall have the right to cease receiving that gas as long as that
condition exists; provided, Buyer shall also curtail all receipts of gas of
similar quality to the same extent as receipts of Seller's gas are curtailed.
Notwithstanding the foregoing, if after commingling that gas with other gas
then in the control of Buyer, the commingled stream is acceptable to all
downstream transporters receiving the commingled stream from Buyer, and as
long as the receipt of that nonconforming gas from Seller does not adversely
affect the economics of Buyer, then Buyer shall continue to receive that gas.
ln the event that Buyer ceases to receive gas as herein provided and if
Seller does not treat the gas prior to delivery hereunder to conform to the
quality specifications, then so long as that gas fails to conform to the
quality specifications Seller shall have the right to deliver the
non-conforming gas to any other party.

         6.       TAXES AND ROYALTY. Buyer shall have no responsibility for
any taxes applicable to the gas delivered hereunder, prior to its delivery to
Buyer, including all production, severance, excise, ad valorem and other
taxes of what ever nature. Buyer shall have no responsibility for any royalty
applicable to the gas delivered hereunder and Seller shall remain fully
responsible for the timely and proper payment of all royalties due on gas
delivered hereunder.

         7.       TITLE AND INDEMNIFY.

         7.1      Seller hereby warrants title to all gas sold hereunder and
that Seller has the right and full authority to sell the same to Buyer,
receive all of the proceeds from that sale, and that all gas is free from any
and all liens and adverse claims. Seller will indemnify Buyer against and
hold Buyer harmless from any and all Losses arising out of or related to
Seller s breach of the foregoing warranty. The foregoing indemnity shall
apply as to any uncertainty, dispute or claim concerning the ownership of
coalbed methane as between the coal estate and the oil and gas estate, but
any such uncertainty, dispute or claim shall not constitute -a breach of the
foregoing warranty by Seller except to the extent of any deliveries by Seller
following an adverse and final, non-appealable court order.

                                       6

<PAGE>

Buyer shall have no obligation to make payments for gas delivered hereunder
until Seller has furnished Buyer with an executed division order or title
opinion (addressed to Buyer) in form and content acceptable to Buyer indicating
that payments for all gas delivered hereunder are to be made to Seller.

         7.2      Seller shall indemnify, defend and hold Buyer harmless from
and against all Losses arising out of Seller's operation hereunder or arising
while the gas is in Seller's exclusive control and possession. Buyer shall
indemnify, defend and hold Seller harmless from and against all Losses
arising out of Buyer's operation hereunder or arising while the gas is in
Buyer's exclusive control and possession. For the purposes of this Agreement,
the gas shall be deemed to be in Seller's exclusive control and possession
until it is delivered to Buyer at the Delivery Point hereunder and after it
is delivered to the Delivery Point under the Gas Sales Agreement; and, the
gas shall be deemed to be in Buyer's exclusive control and possession after
it is delivered to Buyer at the Delivery Point hereunder and until it is
delivered to the Delivery Point under the Gas Sales Agreement.

         8.       Payment.

         8.1      Buyer shall calculate a statement showing the amount of
payment due Seller by Buyer each Accounting Period, and provide Seller with a
copy of the same, on or before the twentieth (20th) day of the month after
deliveries are made. If the actual total quantity of gas delivered and
received hereunder is not available from third party transporter(s) by the
twentieth (20th) day of the month, then Buyer shall provide the statement
based on Buyer's good-faith estimate of deliveries hereunder, which estimates
shall be corrected to reflect actual quantities on the following month's
billing or as soon thereafter as is available.

         8.2      Buyer shall pay for gas delivered and purchased hereunder
by Wire Transfer or ACH as instructed on the invoice, on or before the last
day of the month following the Accounting Period in which deliveries are made.

         8.3      In the event Buyer shall fail to pay any amount due Seller,
when the amount is due, then the overdue amount shall accrue a late payment
penalty at a rate equal to the lesser of (i) one and one half percent (1.5%)
per month, or (ii) the maximum rate permitted by applicable law. In addition
to any other rights provided under this Agreement, including those under
Section 8.4 below, and in addition to any other rights or remedies Seller may
have at law or at equity, if Buyer fails to pay amounts due Seller when due,
then Seller may suspend further delivery of gas until that amount is paid.

         8.4      Prior to the commencement of deliveries and sales of
natural gas under this Agreement, and from time to time thereafter as
requested by Seller, Buyer shall furnish Seller with credit information as
may be reasonably required to determine Buyer's creditworthiness. If during
the term of this Agreement the financial responsibility of Buyer, based upon
credit information supplied to Seller, or based upon Buyer's performance or
lack of performance hereunder, or based upon any other reasonable grounds
which would give rise to insecurity with respect to the performance of Buyer,
then Seller may demand adequate assurance of due performance from Buyer in
form and content reasonably acceptable to Seller, and until Seller receives
that assurance may, as

                                       7

<PAGE>

a non-exclusive remedy, suspend Seller's deliveries of gas hereunder. If
adequate assurance of due performance is not received by Seller within five (5)
days of its demand, then Seller may, in addition to any other rights, claim
repudiation of this Agreement by Buyer. The parties expressly waive any longer
time periods in which to provide adequate assurances as may be contained in
applicable laws or statutes.

         9.       SUCCESSION AND ASSIGNMENT. This Agreement may not be
assigned by either party without the consent of the other party, which
consent shall not be unreasonably withheld. This Agreement, and each of its
terms and conditions, shall bind and inure to the benefit of the Parties
hereto and to their respective successors and assignees. However, any such
assignment must be in writing and shall not be binding on the other Party
unless and until a copy is provided to the other party, and further, shall
not be binding upon Buyer until Buyer has been furnished with appropriate
transfer orders or letters-in-lieu of transfer or division orders.

         10.      FORCE MAJEURE

         10.1     Except for payment due hereunder, neither Party shall be
liable to the other for failure or delay in making or accepting deliveries or
performing other obligations hereunder to the extent that the failure or
delay may be due to Force Majeure conditions.

         10.2     The party claiming Force Majeure must give notice thereof
to the other Party as soon as is reasonably practicable, and shall remedy the
Force Majeure with reasonable diligence.

         10.3     If either party is prevented from performing hereunder to
the full extent of its obligations by Force Majeure conditions for more than
30 consecutive days or more than 90 days in any 12-month period, the other
party shall have the right to terminate this Agreement by providing written
notice to the other party.

         10.4     During any period of Force Majeure, Buyer shall be
authorized to purchase and receive third party gas to replace Seller's unused
Contract Capacity and Seller shall be authorized to sell and deliver its gas
subject to Force Majeure to any third party purchaser.

         11.      REGULATORY BODIES. In the event any regulatory body asserts
jurisdiction over the sale of natural gas hereunder, either party may
terminate this Agreement upon 10 days advance written notice unless, before
that time, the parties are able to agree upon modifications to this Agreement
that restore the economic benefit to the party deprived by the assertion of
that jurisdiction.

         12.      CONFIDENTIALITY. The terms of this Agreement, including,
but not limited to, the price paid for gas, the volumes of gas purchased or
sold, and all other material terms of this Agreement shall be kept
confidential by the Parties hereto, except to the extent that information (i)
is disclosed to the direct consultants (attorneys, accountants, bankers)
working interest and royalty owners whose pro rata share of production is
marketed by a Party, or to prospective purchasers after they have agreed to
be bound by this confidentiality provision, (ii) is disclosed to a downstream
transporter under such transporter's tariff requirements for the purpose of
arranging transportation, or (iii) is disclosed as required by applicable
law, regulation, court order or subpoena.

         13.      MISCELLANEOUS.

         13.1     This Agreement shall be governed in accordance with the
laws of the State of Colorado, without regard to choice of law principles. To
the extent any provisions of this Agreement contradict, vary or are
inconsistent with the provisions of the Uniform Commercial Code, or other
applicable laws, then to the extent permitted by law, and to the extent
provided in this Agreement, this Agreement shall constitute a waiver of those
provisions of the Law.

         13.4     A waiver by either Party of any one or more defaults by the
other in the performance of any provisions of this Agreement shall not
operate as a waiver of any future default, whether of a like or different

                                   MEASUREMENT

                  Seller, or Seller's authorized agent, may, at its option and
expense, install and operate measuring equipment to check Buyer's measuring
equipment provided the installation of the check measuring equipment in no way
interferes with the operation of Buyer's measuring equipment. Any check
measuring equipment installed by Seller shall be located upstream of Buyer's
measuring equipment.

                  All gas volume measurements shall be based on an assumed
atmospheric pressure of twelve-and-seven-tenths (12.7) psia, regardless of
actual atmospheric pressure at which the gas is measured. Gas volume
calculations will be made in accordance with ANSI/API 2530, as amended from time
to time.

                  Buyer shall test the accuracy of its measuring equipment at
least semiannually, or as required by regulatory agencies having jurisdiction.
Buyer shall give Seller, and regulatory agencies having jurisdiction and
entitled to notice, reasonable prior notice of any test or adjustment of any
measuring equipment. Additional test(s) shall be promptly performed upon
notification by either party to the other and the cost of any such additional
tests shall be borne by the requesting party.

                  Upon test, any measuring equipment found to be in error shall
be immediately corrected. If, upon test, the error does not exceed two percent
(2%), the equipment shall be considered correct in computing deliveries
hereunder. If, upon test, the error exceeds two percent (2%), then any preceding
recordings of such equipment shall be corrected to zero error for any period
which is known definitely or agreed upon. If the period is not known definitely
or agreed upon, such correction shall be for a period extending back one-half
(1/2) of the time elapsed since the last test. Correction of deliveries shall be
calculated by the first of the following methods which is feasible: (i) by
correcting the error if the percentage of error is ascertainable by calibration,
test, or mathematical calculations; or (ii) by using the registration of any
check meter or meters installed and accurately registering; or (iii) by
estimating the quantity of delivery by deliveries during periods of similar
conditions when the meter was registering accurately.

                  The composition and BTU content of any gas stream required to
be measured hereunder shall be determined by Buyer semi-annually, or more often
if deemed necessary by Buyer, at the point where the measurement equipment is
located, by chromatographic analysis, or by other industry standard method
mutually acceptable to the parties.

                  Buyer shall at its expense install, operate, and maintain
mutually acceptable "ELECTRONIC FLOW MEASUREMENT" (EFM) and communication
equipment required for data acquisition, at each Delivery Point, in compliance
with API Chapter 21, Section 1, as amended from time to time. Seller and Buyer
shall be jointly responsible for obtaining any necessary approvals and giving
any required notices to the appropriate governmental agencies, including the
Bureau of Land Management, that EFM equipment will be utilized for custody
transfer measurement from Seller to Buyer. Should Seller and Buyer be unable to
obtain any of those requisite approvals, Buyer shall

                                       13

<PAGE>

remove any EFM equipment for which the approval was not obtained and replace
that EFM equipment with acceptable custody transfer measurement equipment. Buyer
shall provide Seller, and its agents, direct access to EFM data through Buyer's
communication equipment.

                  Each party hereto shall have access at all reasonable hours to
all facilities which are related to gas measurement and sampling. Each party
shall have the right to be present for any installing, reading, cleaning,
changing, repairing, testing, calibrating and/or adjusting of either party's
measuring equipment.

not mandate the use of this Contract by any party. GISB DISCLAIMS AND
EXCLUDES, AND ANY USER OF THIS CONTRACT ACKNOWLEDGES AND AGREES TO GISB'S
DISCLAIMER OF, ANY AND ALL WARRANTIES, CONDITIONS OR REPRESENTATIONS, EXPRESS
OR IMPLIED, ORAL OR WRITTEN, WITH RESPECT TO THIS CONTRACT OR ANY PART

                          GENERAL TERMS AND CONDITIONS
                          BASE CONTRACT FOR SHORT-TERM
                        SALE AND PURCHASE OF NATURAL GAS

SECTION 1.   PURPOSE AND PROCEDURES

1.1 These General Terms and Conditions are intended to facilitate purchase and
sale transactions of Gas on a Firm or Interruptible basis. "Buyer" refers to the
party receiving Gas and "Seller" refers to the party delivering Gas.


THE PARTIES HAVE SELECTED EITHER THE "ORAL" VERSION OR THE "WRITTEN" VERSION OF
TRANSACTION PROCEDURES AS INDICATED ON THE BASE CONTRACT.
- -------------------------------------------------------------------------------
ORAL TRANSACTION PROCEDURE:
- -------------------------------------------------------------------------------
1.2 The parties will use the following Transaction Confirmation procedure. Any
Gas purchase and sale transaction may be effectuated in an EDI transmission or
telephone conversation with the offer and acceptance constituting the agreement
of the parties. The parties shall be legally bound from the time they so agree
to transaction terms and may each rely thereon. Any such transaction shall be
considered a "writing" and to have been "signed". Notwithstanding the foregoing
sentence, the parties agree that Confirming Party shall, and the other party
may, confirm a telephonic transaction by sending the other party a Transaction
Confirmation by facsimile, EDI or mutually agreeable electronic means.
Confirming Party adopts its confirming letterhead, or the like, as its signature
on any Transaction Confirmation as the identification and authentication of
Confirming Party.
- -------------------------------------------------------------------------------
WRITTEN TRANSACTION PROCEDURE:
- -------------------------------------------------------------------------------
1.2    The parties will use the following Transaction Confirmation procedure.
Should the parties come to an agreement regarding a Gas purchase and sale
transaction for a particular Delivery Period, the Confirming Party shall, and
the other party may, record that agreement on a Transaction Confirmation and
communicate such Transaction Confirmation by facsimile, EDI or mutually
agreeable electronic means, to the other party by the close of the Business
Day following the date of agreement. The parties acknowledge that their
agreement will not be binding until the exchange of non-conflicting
Transaction Confirmation or the passage of the Confirm Deadline without
objection from the receiving party, as provided in Section 1.3.

1.3    If a sending party's Transaction Confirmation is materially different
from the receiving party's understanding of the agreement referred to in
Section 1.2, such receiving party shall notify the sending party via
facsimile by the Confirm Deadline, unless such receiving party has previously
sent a Transaction Confirmation to the sending party. The failure of the
receiving party to so notify the sending party in writing by the Confirm
Deadline constitutes the receiving party's agreement to the terms of the
transaction described in the sending party's Transaction Confirmation. If
there are any material differences between timely sent Transaction
Confirmations governing the same transaction, then neither Transaction
Confirmation shall be binding until or unless such differences are resolved
including the use of any evidence that clearly resolves the differences in
the Transaction Confirmations. The entire agreement between the parties shall
be those provisions contained in both the Base Contract and any effective
Transaction Confirmation. In the event of a conflict among the terms of (i) a
Transaction Confirmation, (ii) the Base Contract, and (iii) these General
Terms and Conditions, the terms of the documents shall govern in the priority
listed in this sentence.

       EXCEPT AS OTHERWISE SPECIFICALLY PROVIDED HEREIN, IN NO EVENT WILL
EITHER PARTY BE LIABLE UNDER THIS CONTRACT, WHETHER IN CONTRACT, IN TORT

CONSEQUENTIAL, SPECIAL, OR PUNITIVE DAMAGES.

SECTION 4.   TRANSPORTATION, NOMINATIONS AND IMBALANCES

4.1    Seller shall have the sole responsibility for transporting the Gas to
the Delivery Point(s) and for delivering such Gas at a pressure sufficient to
effect such delivery but not to exceed the maximum operating pressure of the
Receiving Transporter. Buyer shall have the sole responsibility for
transporting the Gas from the Delivery Point(s).

4.2    The parties shall coordinate their nomination activities giving
sufficient time to meet the deadlines of the affected Transporter(s). Each
party shall give the other party timely prior notice, sufficient to meet the
requirements of all Transporter(s) involved in the transaction, of the

become aware that actual deliveries at the Delivery Point(s) are greater or
lesser than the Scheduled Gas, such party shall promptly notify the other
party.

4.3    The parties shall use commercially reasonable efforts to avoid
imposition of any Imbalance Charges. If Buyer or Seller receives an invoice
from a Transporter that includes Imbalance Charges, the parties shall
determine the validity as well as the cause of such Imbalance Charges. If the
Imbalance Charges were incurred as a result of Buyer's actions

                                       -5-
<PAGE>


or inactions (which shall include, but shall not be limited to, Buyer's
failure to accept quantities of Gas equal to the Scheduled Gas), then Buyer
shall pay for such Imbalance Charges, or reimburse Seller for such Imbalance
Charges paid by Seller to the Transporter. If the Imbalance Charges were
incurred as a result of Seller's actions or inactions (which shall include,
but not be limited to, Seller's failure to deliver quantities of Gas equal to
the Scheduled Gas), then Seller shall pay for such Imbalance Charges, or
reimburse Buyer for such Imbalance Charges paid by Buyer to the Transporter.

SECTION 5.  QUALITY AND MEASUREMENT

All Gas delivered by Seller shall meet the quality and heat content
requirements of the Receiving Transporter. The unit of quantity measurement
for purposes of this Contract shall be one MMBtu dry. Measure of Gas
quantities hereunder shall be in accordance with the established procedures
of the Receiving Transporter.

SECTION 6.   TAXES

BUYER PAYS AT AND AFTER DELIVERY POINT:
- ------------------------------------------------------------------------------
Seller shall pay or cause to be paid all taxes, fees, levies, penalties,
licenses or charges imposed by any government authority ("Taxes") on or with
respect to the Gas prior to the Delivery Point(s). Buyer shall pay or cause

and all Taxes after the Delivery Point(s). If a party is required to remit or
pay Taxes that are the other party's responsibility hereunder, the party
responsible for such Taxes shall promptly reimburse the other party for such
Taxes. Any party entitled to an exemption from any such Taxes or charges
shall furnish the other party any necessary documentation thereof.

party responsible for such Taxes shall promptly reimburse the other party for
such Taxes. Any party entitled to an exemption from any such Taxes or charges
shall furnish the other party any necessary documentation thereof.
- ------------------------------------------------------------------------------

SECTION 7.   BILLING, PAYMENT AND AUDIT

7.1    Seller shall invoice Buyer for Gas delivered and received in the
preceding Month and for any other applicable charges, providing supporting
documentation acceptable in industry practice to support the amount charged.
If the actual quantity delivered is not known by the billing date, billing
will be prepared based on the quantity of Scheduled Gas. The invoiced
quantity will then be adjusted to the actual quantity on the following
Month's billing or as soon thereafter as actual delivery information is
available.

7.2    Buyer shall remit the amount due in the manner specified in the Base
Contract, in immediately available funds, on or before the later of the
Payment Date or 10 days after receipt of the invoice by Buyer; provided that
if the Payment Date is not a Business Day, payment is due on the next
Business Day following that date. If Buyer fails to remit the full amount
payable by it when due, interest on the unpaid portion shall accrue at a rate
equal to the lower of (i) the then-effective prime rate of interest
published under "Money Rates" by The Wall Street Journal, plus two percent
per annum from the date due until the date of payment; or (ii) the maximum
applicable lawful interest rate. If Buyer, in good faith, disputes the amount
of any such statement or any part thereof, Buyer will pay to Seller such
amount as it concedes to be correct; provided, however, if Buyer disputes the
amount due, Buyer must provide supporting documentation acceptable in
industry practice to support the amount paid or disputed.

                                       -6-
<PAGE>


7.3    In the event any payments are due Buyer hereunder, payment to Buyer
shall be made in accordance with Section 7.2 above.

7.4    A party shall have the right, at its own expense, upon reasonable
notice and at reasonable times, to examine the books and records of the other
party only to the extent reasonably necessary to verify the accuracy of any
statement, charge, payment, or computation made under the Contract. This
examination right shall not be available with respect to proprietary
information not directly relevant to transactions under this Contract. All
invoices and billings shall be conclusively presumed final and accurate
unless objected to in writing, with adequate explanation and/or
documentation, within two years after the Month of Gas delivery. All
retroactive adjustments under Section 7 shall be paid in full by the party
owing payment within 30 days of notice and substantiation of such inaccuracy.

SECTION 8.  TITLE, WARRANTY AND INDEMNITY

8.1    Unless otherwise specifically agreed, title to the Gas shall pass from
Seller to Buyer at the Delivery Point(s). Seller shall have responsibility
for and assume any liability with respect to the Gas prior to its delivery to
Buyer at the specified Delivery Point(s). Buyer shall have responsibility for
and assume any liability with respect to said Gas after its delivery to Buyer
at the Delivery Point(s).

8.2    Seller warrants that it will have the right to convey and will
transfer good and merchantable title to all Gas sold hereunder and delivered
by it to Buyer, free and clear of all liens, encumbrances, and claims.

8.3    Seller agrees to indemnify Buyer and save it harmless from all losses,
liabilities or claims including attorneys' fees and costs of court
("Claims"), from any and all persons, arising from or out of claims of title,
personal injury or property damage from said Gas or other charges thereon
which attach before title passes to Buyer. Buyer agrees to indemnify Seller
and save it harmless from all Claims, from any and all persons, arising from
or out of claims regarding payment, personal injury or property damage from
said Gas or other charges thereon which attach after title passes to Buyer.

8.4    Notwithstanding the other provisions of this Section 8, as between
Seller and Buyer, Seller will be liable for all Claims to the extent that
such arise from the failure of Gas delivered by Seller to meet the quality
requirements of Section 5.

SECTION 9.   NOTICES

9.1    All Transaction Confirmations, invoices, payments and other
communications made pursuant to the Base Contract ("Notices") shall be made
to the addresses specified in writing by the respective parties from time to

9.2    All Notices required hereunder may be sent by facsimile or mutually
acceptable electronic means, a nationally recognized overnight courier
service, first class mail or hand delivered.

9.3    Notice shall be given when received on a Business Day by the
addressee. In the absence of proof of the actual receipt date, the following
presumptions will apply. Notices sent by facsimile shall be deemed to have
been received upon the sending party's receipt of its facsimile machine's
confirmation of successful transmission, if the day on which such facsimile
is received is not a Business Day or is after five p.m. on a Business Day,
then such facsimile shall be deemed to have been received on the next
following Business Day. Notice by overnight mail or courier shall be deemed
to have been received on the next Business Day after it was sent or such
earlier time as is confirmed by the receiving party. Notice via first class
mail shall be considered delivered two Business Days after mailing.

SECTION 10.   FINANCIAL RESPONSIBILITY

10.1   When reasonable grounds for insecurity of payment or title to the Gas
arise, either party may demand adequate assurance of performance. Adequate
assurance shall mean sufficient security in the form and for the term
reasonably specified by the party demanding assurance, including, but not
limited to, a standby irrevocable letter of credit, a

                                       -7-
<PAGE>


prepayment, a security interest in an asset acceptable to the demanding party
or a performance bond or guarantee by a creditworthy entity. In the event
either party shall (i) make an assignment or any general arrangement for the
benefit of creditors; (ii) default in the payment obligation to the other
party; (iii) file a petition or otherwise commence, authorize, or acquiesce
in the commencement of a proceeding or cause under any bankruptcy or similar
law for the protection of creditors or have such petition filed or proceeding
commenced against it; (iv) otherwise become bankrupt or insolvent (however
evidenced); or (v) be unable to pay its debts as they fall due; then the
other party shall have the right to either withhold and/or suspend deliveries
or payment, or terminate the Contract without prior notice, in addition to
any and all other remedies available hereunder. Seller may immediately
suspend deliveries to Buyer hereunder in the event Buyer has not paid any
amount due Seller hereunder on or before the second day following the date
such payment is due.

10.2   Each party reserves to itself all rights, set-offs, counterclaims, and
other defenses which it is or may be entitled to arising from the Contract.

SECTION 11.   FORCE MAJEURE

11.1   Except with regard to a party's obligation to make payment due under
Section 7 and Imbalance Charges under Section 4, neither party shall be
liable to the other for failure to perform a Firm obligation, to the extent
such failure was caused by Force Majeure. The term "Force Majeure" as
employed herein means any cause not reasonably within the control of the
party claiming suspension, as further defined in Section 11.2.

11.2   Force Majeure shall include but not be limited to the following: (i)
physical events such as acts of God, landslides, lightning, earthquakes,
fires, storms or storm warnings, such as hurricanes, which result in
evacuation of the affected area, floods, washouts, explosions, breakage or
accident or necessity of repairs to machinery or equipment or lines of pipe;
(ii) weather-related events affecting an entire geographic region, such as
low temperatures which cause freezing or failure of wells or lines of pipe;
(iii) interruption of firm transportation and/or storage by Transporters;
(iv) acts of others such as strikes, lockouts or other industrial
disturbances, riots, sabotage, insurrections or wars; and (v) governmental
actions such as necessity for compliance with any court order, law, statute,
ordinance, or regulation promulgated by a governmental authority having
jurisdiction. Seller and Buyer shall make reasonable efforts to avoid the
adverse impacts of a Force Majeure and to resolve the event or occurrence
once it has occurred in order to resume performance.

11.3   Neither party shall be entitled to the benefit of the provisions of
Force Majeure to the extent performance is affected by any or all of the
following circumstances: (i) the curtailment of interruptible or secondary
firm transportation unless primary, in-path, firm transportation is also
curtailed; (ii) the party claiming excuse failed to remedy the condition and
to resume the performance of such covenants or obligations with reasonable
dispatch; or (iii) economic hardship. The party claiming Force Majeure shall
not be excused from its responsibility for Imbalance Charges.

11.4   Notwithstanding anything to the contrary herein, the parties agree
that the settlement of strikes, lockouts or other industrial disturbances
shall be entirely within the sole discretion of the party experiencing such
disturbance.

11.5   The party whose performance is prevented by Force Majeure must provide
notice to the other party. Initial notice may be given orally; however,
written notification with reasonably full particulars of the event or
occurrence is required as soon as reasonably possible. Upon providing written
notification of Force Majeure to the other party, the affected party will be
relieved of its obligation to make or accept delivery of Gas as applicable to
the extent and for the duration of Force Majeure, and neither party shall be
deemed to have failed in such obligations to the other during such occurrence
or event.

This Contract may be terminated on 30 days' written notice, but shall remain
in effect until the expiration of the latest Delivery Period of any
Transaction Confirmation(s). The rights of either party pursuant to Section
7.4, the obligations

the other party. Upon any transfer and assumption, the transferor shall not
be relieved of or discharged from any obligations hereunder.
