    2.1   SELLER'S COMMITMENT.  Except as otherwise provided in this
Agreement, Seller commits and dedicates all of Seller's Gas to the
performance of this Agreement that is not dedicated or committed to a
Preexisting Contract.

    2.2   ADDITIONAL GAS FROM NONOPERATED WELLS.  Buyer may, by giving
Seller sixty (60) days' prior written notice, elect to purchase under
this Agreement any gas
                                  -5-


that is produced from the nonoperated wells described in Exhibit D if
(i) in Seller's reasonable business judgment the sale of such gas to
Buyer under this Agreement would not result in a lower gas price or
higher transportation or other costs and expenses than Seller would
receive or pay if such gas is sold through the operator of such wells
and (ii) Seller has the right to sell such gas to Buyer under this
Agreement.  Exhibit A shall be amended from time to time to incorporate
any such wells which become subject to this Agreement pursuant to the
foregoing sentence.  Buyer shall be fully responsible for all
Imbalance Penalties paid by or assessed against Buyer or Seller for
wells added to Exhibit A under this Section 2.2.  

    2.3   RELEASE OF THIRD PARTY GAS.  Upon written request by Seller,
Buyer shall release from this Agreement any Third Party Gas that

sold to third parties under other agreements to avoid incurring
penalties or other costs and expenses if Seller continues to deliver
and sell such Third Party Gas to Buyer under this Agreement. 

    2.4   RIGHT TO CONTROL AND CURTAIL PRODUCTION.  Seller reserves
the right, in its sole discretion, to limit, curtail, or shut-in any
or all of the production of Seller's Gas from any Seller's Well or
Wells for any reason, including, without limitation, inadequate price,
unacceptable market conditions, or any mechanical, engineering, legal,
title, or other field or well condition.  Seller shall use all
reasonable efforts to give notice to Buyer at least thirty (30) Days'
prior to the first Day of any Month in which Seller intends to curtail
or shut-in any quantities of Seller's Gas solely as a result of
Seller's belief that the price received hereunder for such Seller's
Gas is inadequate.  For any other curtailment or shut-in of any
quantities of Seller's Gas, Seller shall give Buyer notice as soon as
reasonably practicable under the circumstances.  Each curtailment
notice shall be in writing and shall identify the quantities of
Seller's Gas that Seller intends to curtail or shut-in and the
expected duration of such curtailment or shut-in period.  Seller shall
not, however, shut in or
                                  -6-


curtail any quantities of Seller's Gas solely for inadequate price
during any Month in which such quantities of Seller's Gas have been
represented as being available for sale to Buyer in Seller's Estimate
given three (3) Days prior to Buyer's Transporter's nomination
deadline for such Month. If Seller returns to production during the
middle of any Month any quantities of Seller's Gas shut-in or
curtailed due to inadequate price, Seller shall give prior written
notice to Buyer and Buyer shall have the right, but not the
obligation, to purchase such Seller's Gas for the balance of such
Month at the gas price determined under Section 8.4.  If Buyer elects
to not purchase such Seller's Gas for the balance of such Month,
Seller may sell such Seller's Gas not purchased by Buyer to any third
party.  At the end of such Month, Buyer shall resume purchasing under
the terms of this Agreement all such Seller's Gas nominated under
Section 4.1.

    2.5   PROCESSING OF GAS.  Seller reserves the right to process
Seller's Gas either prior to the Delivery Points or after delivery to
Buyer at the Delivery Points.  Seller's Gas may be processed to
extract liquid and liquefiable hydrocarbons, together with any methane
unavoidably contained in the ethane or heavier hydrocarbons.  Such
processing will not render the total heating value to be less than the
requirements of the transporter or otherwise cause Seller's Gas to not
meet the quality specifications of the transporter.  All liquid and
liquefiable hydrocarbons so recovered shall belong to Seller.  If
Seller's Gas is processed by Seller after delivery to the Delivery
Points, Seller shall be paid by Buyer for the volumes of residue gas
remaining after processing and Seller shall be responsible for charges
of Buyer's Transporter for the transportation to the processing plant
of fuel and plant volume reduction resulting from such processing.  If
Seller's Gas is processed under percentage of proceeds-type contracts
or other agreements that do not provide for the residue gas
attributable to Seller's Gas to be returned in kind at the tailgate of
the processing plant, Buyer shall
                                  -7-


release such Seller's Gas from this Agreement in writing upon written
request by Seller.  

    2.6   RELEASE OF CERTAIN PROPERTIES.  Buyer shall, if requested by
Seller, promptly release from commitment and dedication hereunder all
Seller's Gas produced from any Seller's Wells if (i) Seller commits to
sell or exchange such Seller's Wells under a written agreement with a
third party which is not an affiliate of Seller and (ii) under such
agreement the average amount of the consideration to be received by
Seller for the gas reserves attributable to Seller's interests in each
such Seller's Well is less than  $250,000 per Seller's Well.  If Seller
desires to sell to a third party and have released from this Agreement
any Seller's Wells that do not meet the requirements of the preceding
sentence, Seller may substitute for such Seller's Wells like
quantities of gas delivered to delivery points reasonably acceptable
to Buyer and with daily deliverabilities during the term of this
Agreement similar to the Seller's Wells which Seller proposes to sell. 
Buyer shall release from commitment under this Agreement such Seller's
Wells effective as of the date such substitute wells become subject to
this Agreement.

    2.7   RELEASE OF CERTAIN NONOPERATED WELLS.  If the Imbalance
Penalties paid or incurred by Seller under this Agreement for any
Seller's Gas produced from any nonoperated Seller's Well become
excessive in Seller's reasonable opinion, Buyer shall, upon written
request by Seller, release such Seller's Gas from commitment under
this Agreement unless Buyer agrees to be responsible for and bear such
Imbalance Penalties for such Seller's Well.  

    2.8   OPERATIONAL RESERVATIONS.  Seller hereby reserves and
excepts the following rights and quantities of Seller's Gas from the
provisions of this Agreement:

    (i)   The right to use Seller's Gas produced from any lease or
    field for Seller's requirements in the development and operation
    of such leases and fields including, but not limited to, use of
    Seller's Gas for drilling, enhanced recovery

                                  -8-

    operations, workover operations, treating, gas lifting oil wells
    for repressuring, recycling, or pressure maintenance purposes,    
    and compressor fuel, and to otherwise operate such leases and
    fields free from any control by Buyer.  Subject to Section 2.9,
    Seller will not, however, use any Seller's Gas for enhanced oil
    recovery operations in California other than Seller's Gas that is
    produced in California.  

    (ii)  Seller's Gas which is delivered to others under Seller's
    leases, Seller's agreements for easements, unit agreements, unit
    operating agreements, operating agreements, or other similar
    agreements affecting Seller's Wells.

    (iii)    All liquids, liquid hydrocarbons, oil, and condensate
    removed from Seller's Gas prior to the Delivery Points.

    (iv)  The right to pool or unitize Seller's leases with other
    leases of Seller or others located in the field in which Seller's
    Wells are located.  

    (v)   The right to operate Seller's leases and Seller's Wells in
    such manner as Seller, in Seller's discretion, deems advisable,
    including the right to drill new wells, to rework Seller's Wells,
    to renew in whole or in part any leases, and to abandon any
    Seller's Well or surrender, release, or terminate any lease, in
    Seller's discretion.

    (vi)  Seller's Gas delivered to others under gas balancing
    agreements or similar arrangements affecting any of Seller's
    Wells.

    2.9   EOR OPERATIONS.  At any time after twenty-four (24) Months
after the Effective Date and upon forty-five (45) Days' prior written
notice from Seller, Buyer shall release from commitment under this
Agreement up to 30,000 MMBtu's per Day of Seller's Gas for use by
Seller in Seller's enhanced oil recovery operations in California or
in exchange for other gas to be used in such operations ("EOR Gas"). 
Buyer shall, at the request of Seller, arrange for the transportation
of EOR Gas from the Delivery Points to Seller's enhanced oil recovery
operations in California using
                                  -9-


either Seller's transportation rights or Buyer's transportation
rights, as directed by Seller.  Seller shall be responsible for
transportation charges to transport EOR Gas to its enhanced oil
recovery operations in California.  In consideration of Buyer
releasing and arranging such transportation for EOR Gas, Seller shall
pay Buyer each Month a handling fee of five cents (5 cents) for each MMBtu
released under this Section 2.9.  EOR Gas shall become recommitted to
this Agreement on the first day of the Month following the date Seller
permanently ceases to use EOR Gas in its California enhanced oil
recovery operations.  Seller shall give Buyer at least fifteen (15)
Days' notice prior to the first day of the Month in which EOR Gas will
become recommitted to this Agreement.

    2.10  ACQUISITION PROPERTIES.  Buyer recognizes that all gas
produced from wells or properties acquired by Seller after the
Effective Date in connection with or as part of the acquisition or
purchase of producing oil and gas properties shall not be subject to
or committed to this Agreement.

    2.11  PREEXISTING CONTRACTS.  Upon the expiration of or
termination of any Preexisting Contract, any Seller's Gas subject to
or covered by such Preexisting Contract shall become committed to this
Agreement without further action of the Parties.  Buyer shall notify
Seller in writing no less than thirty (30) Days before the date each
Preexisting Contract expires or terminates based on the information in
Exhibit C.  If Buyer timely gives Seller such notice, Seller will
exercise its rights to terminate each Preexisting Contract at the end
of its primary term unless the failure to extend the term of any such
Preexisting Contract would cause Seller to pay penalties or to
otherwise incur any costs or expenses for failing to extend the term
of such Preexisting Contract.  Seller shall not, however, have any
obligation to Buyer, and this provision does not create any obligation
upon Seller, to cause the early termination or expiration of any
Preexisting Contract.  
                                 -10-

    2.12  POWER TEX CONTRACT.  Buyer shall, for a period ending not
later than twenty-four (24) Months after the Effective Date and upon
not less than ten (10) days' prior written notice by Seller, release
from commitment under this Agreement up to 4,500 MMBtu's per Day of
Seller's Gas to allow Seller to supply gas under that certain Gas
Sales Agreement between Adobe Gas Marketing Co. and the City of
Lubbock, dated May 9, 1991 (the "Power Tex Contract").  Any such
released Seller's Gas shall become recommitted to this Agreement at
the beginning of the first Month following the end such twenty-four
(24) Month period.

                               ARTICLE 3
                               QUANTITY

    3.1   PURCHASE AND SALE OBLIGATION.  Commencing on the Effective
Date and continuing through the term hereof, Seller agrees, subject to
the other provisions hereof, to sell and deliver, or cause to be
delivered and sold, to Buyer at the Delivery Points the quantity of
Seller's Gas nominated each Month by Seller under Article 4.  Seller
shall use its reasonable efforts to deliver the gas at uniform hourly
and daily rates of flow.  Buyer agrees to take and purchase all of
Seller's Gas delivered each Month at the Delivery Points.

    3.2   FAILURE TO DELIVER OR TAKE.  If for any reason other than
Force Majeure either Party fails in any Month to perform its
obligation to deliver or take Seller's Gas under this Agreement, the
other Party shall use its reasonable efforts to mitigate the effect of
such failure to perform, which includes attempting to secure an
alternate interruptible supply or interruptible market, as the case
may be, at reasonable prices.

    3.3   PARTIAL MONTHLY PRODUCTION.  If Seller delivers to any
Delivery Point after the first day of any Month any quantity of
Seller's Gas that was not previously delivered at any time in such
Month due to Force Majeure affecting Seller or that is

                                 -11-


attributable to the recompletion of an Existing Well or the completion
or recompletion of any Development Well or Exploration Well, Buyer
shall have the obligation to take and purchase such Seller's Gas
during such Month, but only to the extent Buyer is able to arrange
transportation for such Seller's Gas in such Month.  If Buyer is
unable to arrange transportation for such Seller's Gas in such Month,
Seller may sell such Seller's Gas to any third parties during such
Month.  

                               ARTICLE 4
            SCHEDULING AND TRANSPORTATION OF DAILY VOLUMES

    4.1 GAS SCHEDULING.  At least three (3) Days prior to Buyer's
Transporter's nomination deadline for the first Day of the following

Seller's Estimate for each Delivery Point for the following Month. 
Seller shall use its reasonable efforts to provide along with Seller's
Estimate for each Month a description of any planned or foreseeable
events which will materially affect deliveries during the following
Month, including workovers and new Seller's Wells beginning
production.  If the quantity of Seller's Gas delivered to one or more
Delivery Points differs from Seller's Estimate by more than the
transporter's tolerance level for such Delivery Points for any Day or
Days, Seller shall so notify Buyer immediately after becoming aware of
such change by telephone, and shall provide Buyer with a revised
written Seller's Estimate for such Delivery Points for the remainder
of the Month by telecopy as soon as reasonably practicable.  As of the
Effective Date, Buyer shall notify Seller in writing of the Daily and
Monthly tolerance levels for Imbalance Penalties for each transporter
for each Delivery Point.  Such tolerance levels shall remain in effect
until Seller is otherwise notified by Buyer.

                                 -12-

    4.2 TRANSPORTATION CAPACITY.  Buyer shall arrange for and
maintain all necessary transportation downstream of the Delivery
Points to ensure that Seller's Gas flows without interruption, except
in the case of Force Majeure.  

    4.3 TRANSPORTATION IMBALANCES.  

        (a)  AVOIDANCE.  Buyer and Seller shall use all reasonable
    efforts to avoid the imposition of Daily or Monthly Imbalance
    Penalties by any transporter and each Party agrees to cooperate
    with the other Party to resolve and eliminate, to the extent
    reasonably practicable, any Imbalance Penalties.

        (b)  RESPONSIBILITY.  If any Imbalance Penalties are incurred
    or payable to a transporter with respect to Seller's Gas
    delivered to any Delivery Point as a result of Seller's actions,
    including Seller's failure to give Buyer timely notice of any
    increase or decrease in Daily quantities to be delivered at such
    Delivery Point from Seller's Estimate for such Delivery Point,
    Seller shall be responsible for such Imbalance Penalties.  If any
    Imbalance Penalties are incurred or payable to a transporter with
    respect to Seller's Gas delivered to any Delivery Point as a
    result of Buyer's actions, including Buyer's failure to give
    timely notice to such transporter of any change in Seller's
    Estimate for such Delivery Point after receiving timely notice
    from Seller of such change, Buyer shall be responsible for such
    Imbalance Penalties.

        (c)  TIMELY NOTICE.  For the purpose of this Section 4.3,
    Seller's notice will be deemed timely if, under the
    circumstances, it gives Buyer reasonably sufficient time to
    notify the transporter of such changes to Seller's Estimate by
    the time required under the terms of such transporter's Tariff to
    avoid the imposition of such Imbalance Penalties.

        (d)  SELLER'S CREDIT.  In determining the amount of any
    Imbalance Penalties due by Seller hereunder in any Month, Buyer
    shall aggregate the Cashout Costs for which Seller is responsible
    and which were incurred by Buyer
                                 -13-

    for all  transporters for such Month.  Buyer shall, for each such
    Month, credit all such Cashout Costs that resulted in Buyer
    selling gas at a price higher than the applicable Index Price or
    that resulted in Buyer buying gas at a price lower than the
    applicable Index Price ("Buyer's Monthly Gain") against all such
    Cashout Costs that resulted in Buyer buying gas at a price higher
    than the applicable Index Price or that resulted in Buyer selling    
    gas at a price lower than the applicable Index Price ("Buyer's
    Monthly Loss") to arrive at an aggregate net Imbalance Penalty
    for such Month.  If, for any Month, Buyer's Monthly Gain for such
    Month exceeds Buyer's Monthly Loss for such Month, Buyer shall
    have no obligation to refund the difference to Seller.

        (e)  BUYER'S CREDIT.  In determining the amount of any
    Imbalance Penalties due by Buyer hereunder, Seller shall
    aggregate all Cashout Costs for which Buyer is responsible and
    which were incurred by Seller in any Month under operational
    balancing agreements, operating agreements, or other agreements
    covering any Seller's Well.  Seller shall, for each such Month,
    credit all such Cashout Costs that resulted in Seller selling gas
    at a price higher than the applicable Index Price ("Seller's
    Monthly Gain") against all such Cashout Costs that resulted in
    Seller selling gas at a price lower than the applicable Index Price
    or that resulted from Seller buying gas ("Seller's Monthly Loss")
    to arrive at an aggregate net Imbalance Penalty for such Month. 
    If, for any Month, Seller's Monthly Gain exceeds Seller's Monthly
    Loss, Seller shall have no obligation to refund the difference to
    Buyer.

        (f)  LLANO SYSTEM.  Seller shall not be responsible for any
    Imbalance Penalties for Seller's Gas gathered on the Llano
    System.

        (g)  NO LIMIT.  The provisions of this Section 4.3 do not in
    any way waive, limit, or alter either Party's obligation under
    Section 3.1.
                                 -14-

    4.4 ASSIGNMENT OF GATHERING CONTRACTS.  As of the Effective Date,
Seller shall assign to Buyer, to the extent Seller has the contractual
right to do so, any agreements entered into prior to the Effective
Date with third parties for the gathering of Seller's Gas.  If Seller
is required to obtain the consent or approval of any third party to
assign any or all of such agreements to Buyer, Seller shall use its
reasonable efforts to obtain any and all third-party consents and
approvals as quickly as reasonably practicable.  If Seller does not
have the legal right to assign any such agreement, then Seller shall
authorize Buyer to act as Seller's agent under such agreements.  Buyer
shall administer all such agreements so that they remain valid and
enforceable in accordance with their terms.  Buyer shall obtain the
consent of Seller prior to releasing, amending, or otherwise modifying
such agreements.  Upon termination or expiration of this Agreement,
Buyer shall reassign to Seller or its designee all such agreements

    4.5 DELIVERY POINTS.  As of the Effective Date, Buyer and Seller
have agreed that Seller's Gas will be delivered and accepted at the
Delivery Points described in Exhibit A.  The parties shall mutually
agree to the Delivery Point for each Development Well or Exploration
Well which subsequently produces Seller's Gas subject to this

by both Parties.

    4.6 DELIVERY DIFFERENCES.  If at the end of the first six (6)
Months of this Agreement, the aggregate quantity of Seller's Gas
delivered by Buyer for each Month to any interstate pipeline has been
materially different from Seller's Estimate for such Seller's Gas made
by Seller three (3) Days prior to the nomination deadline of the
applicable Buyer's Transporter for each such Month, except as allowed
under the provisions of this Agreement, Seller shall, upon Buyer's
written request, use all reasonable efforts to promptly correct such
differences in the following two (2)

                                 -15-

two (2) Months, Buyer may request the renegotiation of Buyer's payment
hereunder of the Index Price for such differences and allocation among
the Parties of any benefits or costs to Buyer arising out of such
differences for the remaining term of this Agreement.  If Buyer and
Seller are unable to mutually agree on the price to be paid for such
differences and such allocation, such matter may be submitted by
either Party to Arbitration as a Dispute under Article 9.

    5.1 CONNECTION OF GATHERING SYSTEMS - EXPLORATION WELLS.  Within
thirty (30) Days of the drilling and completion of any well producing
commercial quantities of gas on the Exploration Lands, Seller shall
notify Buyer of the completion of such well and provide Buyer with all
available well test data including, without limitation, all well logs,
drill stem tests, well potential tests, and Seller's estimate of well
deliverability and ultimate recoverable reserves.  Within twenty (20)
Days after receipt of Seller's notice, Buyer shall submit to Seller,
in writing, for Seller's review, Buyer's recommendation of the most
economical and efficient method of gathering and transporting the gas
produced from such well, whether by Buyer, Seller, or third parties
("Buyer's Gathering Proposal").  Seller may, in its discretion, either
accept or reject Buyer's Gathering Proposal by giving written notice
to Buyer.  If Seller accepts Buyer's Gathering Proposal, Buyer shall
promptly commence and diligently complete the work necessary to
implement Buyer's Gathering Proposal, and, upon completion of such
gathering system, Seller will sell the gas produced from such well to
either Buyer or a third party, as provided in Buyer's Gathering
Proposal.  If the gas produced from such well is sold to Buyer under
this Agreement, such well shall become committed to this Agreement as
an Exploration Well.  If Seller rejects

                                 -16-


Buyer's Gathering Proposal, Seller may contract with any third parties
to gather and purchase the gas produced from such well without any
obligation to Buyer under this Agreement.  

    5.2 DEVELOPMENT WELLS.  Upon completion of each Development Well,
Buyer shall, if requested by Seller, recommend the most economical
method of gathering the gas produced from such Development Well.

    5.3 MARKETING UPDATES.  Buyer shall, upon request, provide Seller
written updates and verbal briefings on gas market trends including,
but not limited to, the development of new natural gas markets or

In addition, Buyer shall periodically provide written updates on
regulatory trends and developments in both the domestic and
international gas market that could impact Seller.

    5.4 SUPPLY OF GAS UNDER POWER TEX CONTRACT.  Upon request by
Seller, during the first twenty-four (24) Months of this Agreement,

value, and testing specifications of Seller's Gas delivered to each
Delivery Point.  

    6.2 QUALITY.  Seller's Gas shall meet the quality specifications
of Buyer's Transporter at each Delivery Point.  If all or any portion
of the Seller's Gas does not
                                 -17-


meet the quality specifications of Buyer's Transporter, Buyer at its
option may at any time refuse to accept any or all such Seller's Gas
("Subquality Gas").  Acceptance of any or all Subquality Gas that
fails to conform to the quality specifications of this Agreement shall
not be deemed a waiver of Seller's obligations hereunder with respect
to such Subquality Gas or with respect to any future deliveries of
Subquality Gas.  All Subquality Gas which Buyer fails to take under
this Section 6.2 may be sold to any third parties free from any
obligation under this Agreement during the period Buyer refuses to
accept such Subquality Gas.  SELLER MAKES NO OTHER WARRANTIES,
EXPRESS, IMPLIED, STATUTORY, OR OTHERWISE, INCLUDING WARRANTIES OF
MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE, ABOUT SELLER'S
GAS.

quantities of Seller's Gas after the Delivery Points, the risk of loss
for such Seller's Gas shall pass from Buyer to Seller where such
Seller's Gas enters the facilities of the party processing such
Seller's Gas.  The risk of loss to the residue gas resulting from
processing such Seller's Gas shall pass to Buyer where it enters the
facilities of Buyer's transporter at or near the tailgate of such
processing facilities.

deemed to be in control and possession of Seller's Gas and shall be
fully responsible for and shall defend and indemnify Buyer, its
successors and assigns, against any damages or injury resulting from
the operation of facilities used to deliver gas at the Delivery
Points, or the possession and handling of such Seller's Gas, until
delivered to Buyer or

Buyer's Transporter at the Delivery Points and during the period such
Seller's Gas, if processed, is in the facilities of the processor.

defend and indemnify Seller, its successors and assigns, against any
and all damages or injury resulting from the transportation, handling,

Article 8, for all Seller's Gas delivered to each Delivery Point each
Month, Buyer shall pay Seller a gas price per MMBtu equal to the Index
Price for each such Delivery Point for such Month less Transportation
Expenses, if any, for such Seller's Gas for such Month.

    8.2 PRICING COMBINATION.  Buyer shall, for each Month, use its
best efforts to obtain for Seller at each Delivery Point the Index

Buyer at any Delivery Point under Section 3.3 and for all Seller's Gas
returned to production in the middle of a Month under Section 2.4
after being shut-in or curtailed due to inadequate price, the average
of the high and low prices per MMBtu published in the table "Daily
Price Survey" in GAS DAILY for the first Day of deliveries for the
region of production for such Delivery Point shall be substituted for
the Index Price in determining the price to be paid by Buyer to Seller
for such Seller's Gas under Section 8.1.

    8.5 LLANO SYSTEM TRANSPORTATION RATE.  The Transportation
Expenses for Seller's Gas gathered on the Llano System shall never
exceed in any Month the lowest transportation rate charged by Buyer to

except for any such rate which may be agreed to by Llano Inc., in its
discretion, as part of the settlement of any claim made against Llano
Inc. or its affiliates.

    8.6 TRANSPORTATION EXPENSES.  Buyer shall, for each Delivery
Point, use its best efforts each Month to obtain for Seller the lowest
reasonably available transportation rates on Buyer's Transporter for
Seller's Gas, consistent with reliability and giving consideration to
Buyer's obligation to purchase and take all of Seller's Gas at such
Delivery Point and to Seller's right to shut-in or curtail production
of Seller's Gas hereunder.

additional information or documentation from either Party, which
information or documentation shall be timely provided.  No later than
twenty (20) Working Days after the counterproposals are submitted, the
Arbitrators shall select and adopt either the outcome desired by
Seller or the outcome desired by Buyer, without modification or
compromise.  All Arbitrations shall take place in Houston, Harris
County, Texas.

    recognize that the Parties selected INSIDE FERC as representative
    of the fair market value of Seller's Gas at each Pricing Point on
    the Effective Date;  

        (ii)     The Index Price shall be reported on a Monthly basis
    from a publication or other information source publicly
    available; and

shall be determined from the last such publication or information
source that was
                                 -22-


available.  Upon the conclusion of the Arbitration, the price paid by
Buyer to Seller for such Seller's Gas shall be adjusted retroactively
to the date the Arbitration was invoked.  The Party owing the other
Party as a result of such retroactive adjustment shall pay to such
other Party the amounts due under the redetermined Index Price within
ten (10) Working Days following the Arbitrator's decision.

    9.6 FINALITY OF AWARD AND COSTS OF ARBITRATION.  The
determination of the Arbitrators shall be final and binding on the
Parties, except in the event of manifest material error or misconduct
by the Arbitrators.  Each Party shall bear its own costs and expenses

federal, Indian, state or local sales, use, consumption, and/or
similar taxes which may now or hereafter be imposed on the transfer of
title or possession of Seller's Gas.
