      Delivery of the Gas produced and saved from the Leases described herein.
      Each meter installed by Buyer/Processor shall be a meter acceptable in the
      industry and each meter shall be installed and operated in accordance with
      the physical requirements of American Gas Association Gas Measurement
      Committee Report No. 3, dated April, 1955, 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
      Seller at all reasonable times. The charts and records pertaining to
      measurement hereunder shall be kept on file by Buyer/Processor 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 Buyer/Processor if found to be

semi-annually Buyer/Processor shall calibrate all meters installed hereunder and
make adjustments as necessary. Should Seller so desire, Buyer/Processor shall
give notice to Seller of the time of such calibrations sufficiently in advance
of holding same in order that Seller 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 (10030 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

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

            

    

     

    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 1n
accordance with the standards prescribed in American Gas Association Gas
Measurement Committee Report No. 3, dated April, 1955, 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 atmospheric pressure shall be assumed to be 12.3 pounds
Psia. The temperature of Gas flowing through each meter shall be determined by a
recording thermometer, installed by Buyer/Processor 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 volumes delivered hereunder to a
temperature base of sixty degrees Fahrenheit (60°F) and to a pressure base of
14.65 pounds Psia.

              1.

            	
              For
      purposes of determining Plant Product Revenues attributable to Seller's
      Gas, Buyer/Processor shall multiply the volume in MCF's of Gas
      attributable to each of Seller's wells by the GPM (Gallons Per MCF) of
      each Plant Product contained in the well stream. Said GPM shall be
      determined by chromatograph analysis taken on spot Gas samples from each
      of Seller's wells and adjusted on an annual basis. The calculated value
      will be the Total Theoretical Plant Product Content of the Seller's Gas.
      Said Total Theoretical Plant Product Content shall be divided by the Total
      Theoretical Plant Product Content of all Gas received and purchased by
      Buyer/Processer to determine the percentage of Total Plant Products
      attributable to each of Seller's wells. Division of revenues from Total
      Plant Products shall be made per the pricing provisions contained
      herein.

              2.

            	
              For
      the purpose of determining Residue Gas Revenues attributable to Seller's
      Gas, Buyer/Processor shall divide the volume in MCF's of Gas attributable
      to each of Seller's wells by the total volume in MCF's of all Gas received
      and purchased by Buyer/Processor. This fraction shall be multiplied by the
      total Residue Gas Volume to determine the Residue Gas Volume attributable
      to each of Seller's wells. Division of Residue Gas Revenues between
      Buyer/Processor and Seller shall be determined pursuant to the pricing
      provisions contained herein.

            

    

    

    
      	
              3.

            	
              Buyer/Processor
      will market one hundred percent (100%) of the Plant Products upon terms
      which, in Buyer/Processor's sole judgment, are the best terms then
      available. Buyer/Processor will furnish Seller on a monthly basis with
      reports containing volumes sold by product and the price received
      therefore. Seller shall have the right at reasonable times during normal
      business hours to review the books and records of Buyer/Processor
      pertaining to the sale of Plant Products, Residue Gas and revenues
      received therefrom.

      the System relating to the gathering and processing of Seller's Gas. After
      payout, Seller shall receive [ * ] percent [ * ] of the
      Residue  Gas Revenues attributable to each of Seller's wells.
      Total Residue Gas Revenue attributable to each of Seller's wells shall be
      calculated by multiplying the Residue Gas Volume attributable to each of
      Seller's wells by the then effective price per MCF being received by
      Buyer/Processor. All pricing terms and conditions shall be determined
      pursuant to the terms and provisions contained in the Residue Gas and
      Sales and Purchase Agreement(s) between Buyer/Processor and Western Slope
      Gas Company, dated February 17,

      Costs attributable to Seller's Gas. Plant Operating Costs attributable to
      Seller's Gas, for the purpose of determining payout, shall be shared
      proportionately by Seller by multiplying the total Plant Operating Costs
      by the ratio of Seller's Gas delivered thereto to the total volumes of Gas
      received and purchased by Buyer/Processor at the

    UNECONOMIC WELL CONNECTIONS
AND UNECONOMIC OPERATIONS OF PLANT

    

    
      	
              1.

            	
              The
      Buyer/Processor will either install, or cause to be installed a System to
      connect and receive Gas from Seller's wells, which, in Buyer/Processor's
      sole opinion, is economically feasible to gather. If in Buyer/Processor's
      sole opinion it is uneconomic to connect one of Seller's wells to
      Buyer/Processor's Gathering System, Buyer/Processor shall be under no
      obligation to do so, or to accept any Gas produced from said well. If
      Buyer/Processor elects not to construct a System and connect a well,
      Buyer/Processor nevertheless may, upon Seller's request, accept Gas from
      any such well or lease if Seller shall acquire and assign without charge
      to Buyer/Processor, a measuring station site on Buyer/Processor's existing
      Gathering System at a mutually agreeable point, together with all
      necessary rights of ingress and egress thereto, and shall bear the cost of
      constructing, operating, and maintaining all facilities necessary to
      deliver the Gas from such well into Buyer/Processor's Gathering System at
      said mutually agreeable point. Should Seller elect not to deliver Gas from
      such well, Buyer/Processor shall release from this Agreement such well and
      the acreage attributable thereto, but only as to the formation in which
      such well is then completed.

            

    

    

    Buyer/Processor
will install or cause to be installed a System to receive Seller's Gas from
Seller's wells, which, in Buyer/Processor's opinion are economically feasible to
gather. An economic well shall be defined as a well which will produce a
stabilized flow after six (6) months of [*]
MCF
per day of Gas per mile of pipeline installed by Buyer/Processor to receive
Seller's Gas. Should Buyer/Processor connect Seller's well and said well
produces a stabilized flow after six (6) months of less than [*] MCF per day per mile of pipeline
installed by Buyer/Processor to receive Seller's Gas, Seller shall indemnify
Buyer/Processor for all costs of said connection, adjusted for actual length of
pipeline and proportional to the ratio of actual stabilized volume at the end of
six (6) months to [*] MCF
per day. The terms of said indemnification shall be negotiated between
Buyer/Processor and Seller.

    

    Should
Buyer/Processor and Seller determine prior to connection of Seller's well that
said well will not meet the criteria for an economic well connection,
Buyer/Processor shall install the necessary System required to connect Seller's
well to Buyer/Processor's Gathering System upon receiving a written
indemnification from Seller of Buyer/Processor's actual cost for said System
pursuant to the terms above.

              2.

            	
              If,
      in the opinion of Buyer/Processor, the Plant is or becomes uneconomic to
      operate due to its volume, quality, plant product content, governmental
      regulation or any other cause, Buyer/Processor may either modify or
      suspend Plant operations, in which case Buyer/Processor shall not be
      obligated to take delivery of, or may cease processing the Gas from
      Seller's wells, so long as such condition exists. For the purposes hereof,
      "uneconomic operation" shall be defined as circumstances under which
      Buyer/Processor's share of net operating revenues of the Plant is
      insufficient to offset actual Plant operating
  costs.

            

    

    

    
      	
              3.

            	
              During
      periods of uneconomic operation of the Plant and/or suspension of
      operation of portions thereof. Buyer/Processor, at the request of the
      Seller, shall place back in service and operate such suspended portions of
      the Plant as may be necessary to accept and process Seller's Gas. In
      consideration thereof, Seller agrees to reimburse Buyer/Processor, in the
      same proportion as the ratio of the Gas volumes supplied by Seller bear to
      the total Gas volumes supplied to the Plant by other third-party sellers,
      for any losses (costs of Plant operations in excess of revenues
      attributable to Plant operations after deducting payments to all
      contributing producers for Gas delivered to and processed by the Plant)
      incurred by Buyer/Processor during such continued uneconomic operations.
      Buyer/Processor may, at its option, elect to sell the Plant rather than
      operate the same under the terms of this paragraph. In such event, Seller
      shall be given notice thereof and first right of refusal to purchase its
      proportionate share of the Plant from Buyer/Processor based upon Seller's
      then dedicated capacity thereof upon terms to be negotiated between the
      parties.

              Crude
      Oil Purchase Option: Seller is currently marketing all crude oil and/or
      condensate produced from wells drilled on the Leases dedicated hereunder
      and in which Seller owns, has an interest, or is otherwise authorized to
      market to a legitimate crude oil purchaser other than Associated Natural
      Gas, Inc. which is active in the area of said Leases pursuant to a written
      agreement currently in effect.

            

    

    

    If, upon
expiration of the primary term of the crude oil purchase agreement between
Seller and the current purchaser, or effective January 1, 1984, whichever shall
first occur, should seller receive a bona fide written offer from either its
current purchaser or any other bona fide purchaser of crude oil at a price per
barrel of less than fifty ($.50) cents above that then being offered by
Associated Natural Gas, Inc., which is a price equal to the highest published
price of a major oil company for the area in question, Seller shall notify
Associated Natural Gas, Inc., at which time Associated Natural Gas, Inc., as an
independent contractor, shall be given an option and right of first refusal, to
be exercised within fifteen (15) days from receipt of such notice, to purchase
all of Seller's crude oil and/or condensate above referenced at a price
equivalent to the highest published posted price of a major oil company for the
area in question. In the event Associated Natural Gas exercises it option,
Seller agrees to enter into a Crude 011 Purchase Agreement with Associated
Natural Gas, Inc.

    In the
event Seller should receive a bona fide written offer from such purchaser at a
price per barrel differential of fifty ($.50) cents or more above that then
being offered by Associated Natural Gas, Inc., Seller shall notify Associated
Natural Gas, Inc., at which time Associated Natural Gas, Inc., as an independent
contractor, shall be given an option and right of first refusal, to be exercised
within fifteen (15) days from receipt of such notice, to purchase all of
Seller's crude oil and/or condensate at an equivalent price. In the event
Associated Natural Gas, Inc. exercises its option, Seller agrees to enter into a
Crude Oil Purchase Agreement with Associated Natural Gas, Inc., at such
price.

    

    In the
event Associated Natural Gas, Inc. fails to exercise any option above provided
within the fifteen (15) day period, Seller may accept the outstanding bona fide
written offer and market its crude oil and/or condensate to such purchaser for
the primary term of such agreement, the notice and option process set out above
shall be repeated.

    SHRINKAGE

    

    Buyer/Processor
agrees to use ordinary care in transporting the Gas produced by Seller and
purchased and gathered by Buyer/Processor hereunder to its point of delivery at
the Plant, and after processing such Gas, deliver the Gas to its purchaser at
the tailgate of said Plant. However, the parties understand and agree that
certain volumetric gains and losses in the Gas will occur and shall be shared by
and among Seller and other third-party sellers, whose Gas is also being
purchased by Buyer/Processor and transported to the Plant, in the proportion
that each party delivers Gas into Buyer/Processor's Gathering System at their
respective Point(s) of Delivery.

    GENERAL
PROVISIONS

    
      DOMESTIC CRUDE OIL
AGREEMENTS

      

      

      A.       
    Measurement and Tests:  All measurements
hereunder shall be made from static tank gauges on 100 percent tank table basis
or by positive displacement meters.  All measurements and tests shall
be made in accordance with the latest ASTM or ASME-API (Petroleum PD Meter Code)
published methods then in effect whichever apply.  Volume and gravity
shall be adjusted to 60 degrees Fahrenheit by the use of Table 6A and 5A of the
petroleum Measurement Tables ASTM Designation D1250 in their latest
revision.  The crude oil delivered hereunder shall be marketable and
acceptable in the applicable common or segregated stream of the carriers
involved but not to exceed 1% S&W.  Full deduction for all free
water and S&W content shall be made according to the API/ASTM Standard
Method then in effect.  Either party shall have the right to have a
representative witness all gauges, tests and measurements.  In the
absence of the other party’s representative, such gauges, tests and measurements
shall be deemed to be correct.

      
        B.           Warranty:
The Seller warrants good title to all crude oil delivered hereunder and warrants
that such crude oil shall be free from all royalties, liens, encumbrances and
all applicable foreign, federal, state and local taxes.

        Seller further warrants that the crude
oil delivered shall not be contaminated by chemicals foreign to virgin crude oil
including, but not limited to chlorinated and/or oxygenated hydrocarbons and
lead.  Buyer shall have the right, without prejudice to any other
remedy available to Buyer, to reject and return to Seller any quantities of
crude oil which are found to be so contaminated, even after delivery to
Buyer.
C.         
  Rules and Regulations:  The terms, provisions and
activities undertaken pursuant to this Agreement shall be subject to all
applicable laws, orders and regulations of all governmental
authorities.  If at any time a provision hereof violate any such
applicable laws, orders or regulations, such provision shall be voided and the
remainder of the Agreement shall continue in full force and effect unless
terminated by either party upon giving written notice to the other party
hereto.  If applicable, the parties hereto agree to comply with all
provisions (as amended) of the Equal Opportunity Clause prescribed in 41 C.F.R.
60-1.4; the Affirmative Action Clause for disabled veterans and veterans of the
Vietnam Era prescribed in 41 C.F.R. 60-250.4; the Affirmative Action Clause for
Handicapped Workers prescribed in 41 C.F.R. 60-741.4; 46 C.F.R. Chapter 1
Subpart 19.7 regarding Small Business and Small Disadvantaged Business Concerns;
48 C.F.R. Chapter 1 Subpart 20.3 regarding Utilization of Labor Surplus Area
Concerns; Executive Order 12138 and regulations thereunder regarding

Fair Labor Standards Act of 1938 as amended, all of which are incorporated in
this Agreement by reference.

      D.      
     Hazard Communication:  Seller shall
provide its Material Safety Data Sheet (“MSDS”) to Buyer.  Buyer
acknowledges the hazards and risks in handling and using crude
oil.  Buyer shall read the MSDS and advise its employees, its
affiliates, and third parties, who may purchase or come into contact with such
crude oil, bout the hazards of crude oil, as well as the precautionary
procedures for handling said crude oil, which are set forth in such MSDS and any
supplementary MSDS or written warning(s) which Seller may provide to Buyer from
time to time.

      E.           Force
Majeure:  Except for payment due here under, either party here to
shall be relieved from liability for failure to perform hereunder for the
duration and to the extent such failure is occasioned by war, riots,
insurrections, fire, explosions, sabotage, strikes, and other labor or
industrial disturbances, acts of God or the elements, governmental laws,
regulations or requests, acts in furtherance of the International Energy
Program, disruption or breakdown of production or transportation facilities,
delays of pipeline carrier in receiving and delivering crude oil lendered, or by
any other cause, whether similar or not, reasonably beyond the control of such
party.  Any such failures to perform shall be remedied with all
reasonable dispatch, but neither party shall be required to supply substitute
quantities from other sources of supply.  Failure to perform due to
events of Force Majeure shall not extend the terms of this
Agreement.

      Notwithstanding
the above, and in the event that the Agreement is an associated purchase/sale,
or exchange of crude oil, the parties shall have the rights and obligations
described below in the circumstances described below:

      (1)           If,
because of Force Majeure, the party declaring Force Majeure (the “Declaring
Party”) is unable to deliver part or all of the quantity of crude oil which the
Declaring Party is obligated to deliver under the Agreement or associated
contract, the other party (the “Exchange Partner”) shall have the right but not
obligation to reduce its deliveries of crude oil under the same Agreement or
associated contract by an amount not to exceed the number of barrels of crude
oil that the Declaring Party fails to deliver.

      (2)           If,
because of Force Majeure, the Declaring Party is unable to take delivery of part
or all of the quantity of crude oil to be delivered by the Exchange Partner
under the Agreement or associated contract, the Exchange Partner shall have the
right but not the obligation to reduce its receipts of crude oil under the same
Agreement or associated contract by an amount not to exceed the number of
barrels of crude oil that the Declaring Party fails to take delivery
of.

      F.     
      Payment:  Unless otherwise
specified in the Special Provisions of this Agreement, Buyer agrees to make
payment against Seller’s involved for the crude oil purchased hereunder to a
bank designated by Seller in U.S. dollars by telegraphic transfer in immediately
available funds.  Unless otherwise specified in the Special Provisions
of this Agreement, payment will be due on or before the 20th of the month
following the month of delivery.  If payment due date is on a Saturday
or New York bank holiday other than Monday, payment shall be due on the
preceding New York banking day.  If payment due date is on a Sunday or
a Monday New York bank holiday, payment shall be due on the succeeding New York
banking day.

      Payment
shall be deemed to be made on the date good funds are credited to Seller’s
account at Seller’s designated bank.

      In the
event that Buyer fails to make any payment when due, Seller shall have the right
to charge interest on the amount of the overdue payment at a per annum rate
which shall be two percentage points higher than the published prime lending
rate of Morgan Guaranty Trust Company of New York on date payment was due, but
not to exceed the maximum rate permitted by law.

      

      

      Effective
January 1, 1993

      Supersedes
November 1983 General Provisions

      
        
           

        

        
           

          
            

          

        

        
           

        

      

      G.        
    Financial Responsibility:  Notwithstanding
anything to the contrary in this Agreement, should Seller reasonably believe it
necessary to assure payment, Seller may at anytime require, by written notice to
Buyer, advance cash payment or satisfactory security in the form of a Letter or
Letters of Credit at Buyer’s expense in a form and from a bank acceptable to
Seller to cover any or all deliveries of crude oil.  If Buyer does not
provide the Letter of Credit on or before the date specified in Seller’s notice
under this section, Seller or Buyer may terminate this Agreement
forthwith.  However, if a Letter of Credit is required under the
Special Provisions of this Agreement and Buyer does not provide same, then
Seller only may terminate this Agreement forthwith.  In no event shall
Seller be obligated to schedule or complete delivery of the crude oil until said
Letter of Credit is found acceptable to Seller.  Each party may offset
any payments or deliveries due to the other party under this or any other
agreement between the parties.

      If a
party to this Agreement (the “Defaulting Party”) should (1) become the subject
of bankruptcy or other insolvency proceedings, or proceedings for the
appointment of a receiver, trustee, or similar official, (2) become generally
unable to pay its debts as they become due, or (3) make a general assignment for
the benefit of creditors, the other party to this Agreement may withhold
shipments without notice.

      H.     
      Liquidation:

      (1)           Right
to Liquidate.  At any time after the occurrence of one or more of the
events described in the third paragraph of Section G, Financial Responsibility,
the other party to the Agreement (the “Liquidating Party”) shall have the right
at its sole discretion, to liquidate this Agreement by terminating this
Agreement.  Upon termination, the parties shall have no further rights
or obligation with respect to this Agreement, except for the payment of the
amount(s) (the “Settlement Amount” or “Settlement Amounts”) determined as
provided in Paragraph (3) of this section.

      (2)           Multiple
Deliveries.  If this Agreement provides for multiple deliveries of one
or more types of crude oil in the same or different delivery months, or for the
purchase or exchange of crude oil by the parties, all deliveries under this
Agreement to the same party at the same delivery location during a particular
delivery months hall be considered a single commodity transaction (“Commodity
Transaction”) for the purpose of determining the Settlement
Amount(s).  If the Liquidating Party elects to liquidate this
Agreement, the Liquidating Party must terminate all Commodity Transactions under
this Agreement.

      (3)           Settlement
Amount.  With respect to each terminated Commodity Transaction, the
Settlement Amount shall be equal to the contract quantity of crude oil,
multiplied by the difference between the contract price per barrel specified in
this Agreement (the “Contract Price”) and the market price per barrel of crude
oil on the date the Liquidating Party terminates this Agreement (the “Market
Price”).  If the Market Price exceeds the Contract Price in a
Commodity Transaction, the selling party shall pay the Settlement Amount to the
buying party.  If the Market Price is less than the Contract Price in
a Commodity Transaction, the buying party shall pay the Settlement Amount to the
selling party.  If the Market Price is equal to the Contract Price in
a Commodity Transaction, no Settlement Amount shall be due.

      (4)           Termination
Date.  For the purpose of determining the Settlement Amount, the date
on which the Liquidating Party terminates this Agreement shall be deemed to be
(a) the date on which the Liquidating Party sends written notice of termination
to the Defaulting Party, if such notice of termination is sent by telex or
facsimile transaction; or (b) the date on which the Defaulting Party receives
written notice of termination from the Liquidating Party, if such notice of
termination is given by United States mail or a private mail delivery
service.

      (5)            Market
Price.  Unless otherwise provided in this Agreement, the Market Price
of crude oil sold or exchanged under this Agreement shall be the price for crude
oil for the delivery month specified in this Agreement and at the delivery
location that corresponds to the delivery location specified in this Agreement,
as reported in Platt’s Olgram Price Report (“Platt’s”) for the date on which the
Liquidating Party terminates this Agreement.  If Platt’s reports a
range of prices for crude oil on that date, the Market Price shall be the
arithmetic average of the high and low prices reported by Platt’s.  If
Platt’s does not report prices for the crude oil being sold under this
Agreement, the Liquidating Party shall determine the Market Price of such crude
oil in a commercially reasonable manner, unless otherwise provided in this
Agreement.

      (6)           Payment
of Settlement Amount.  Any Settlement Amount due upon termination of
this Agreement shall be paid in immediately available funds within two business
days after the Liquidating Party terminates this Agreement.  However,
if this Agreement provides for more than one Commodity Transaction, or if
Settlement Amounts are due under other agreements terminated by the Liquidating
Party, the Settlement Amounts due to each party for such Commodity Transactions
and/or agreements shall be aggregated.  The party owing the net amount
after such aggregation shall pay such net amount to the other party in
immediately available funds within two business days after the date on which the
Liquidating Party terminates this Agreement.

      (7)            Miscellaneous.  This
section shall not limit the rights and remedies available to the Liquidating
Party by law or under other provisions of this Agreement.  The parties
hereby acknowledge that this Agreement constitutes a forward contract for
purposes of Section 556 of the U.S. Bankruptcy Code.

      I.         
    Equal Daily Deliveries:  For price purposes
only, unless otherwise specified in the Special Provision, all crude oil
delivered hereunder during any calendar month shall be considered to have been
delivered in equal daily quantities during such month.

      J.         
    Exchange Balancing:  If volumes are exchanged,
each party shall be responsible for maintaining the exchange in balance on a
month-to-month basis, as near as pipeline or other transportation conditions
will permit.  In all events upon termination of this Agreement and
after all monetary obligations under this Agreement have been satisfied, any
volume imbalance existing at the conclusion of this Agreement of less than 1,000
or more, limited to the total contract volume, will be settled by the
underdelivering party making delivery of the total volume imbalance in
accordance to the delivery provisions of this Agreement applicable to the
underdelivering party, unless mutually agreed to the contrary.  The
request to schedule all volume imbalances must be confirmed in writing by one
party or both parties. Volume imbalances confirmed by the 20th of the month
shall be delivered during the calendar month after the volume imbalance is
confirmed.  Volume imbalances confirmed after the 20th of the month
shall be delivered during the second calendar month after the volume imbalance
is confirmed.
