              Buyer/Processor
      shall furnish and install a suitable orifice meter at the Point(s) of
      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
      incorrect.

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
available data, using the first of the following methods which is
feasible:

              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.

    ALLOCATION OF RESIDUE GAS
AND PLANT

              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,

      operating income will be comprised of Buyer/Processor's Residue Gas and
      Plant Product Revenues attributable to Seller's Gas, less Plant Operating
      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
  Plant.

      including death, or damage to property arising out of or incident to
      Buyer/Processor's use of the easement hereunder transferred, only in the
      event said claim or damage shall be the result of negligence legally
      imputable to Buyer/Processor; its employees, agents, and

    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.
