      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

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.

in-line transfer, delivery of the crude oil to the Buyer shall be effected at
the particular pipeline facility designated in this Agreement.  Title

      ] percent ([ * ]%) for Low Pressure Receipt Point(s)
      and [ * ]  percent ([ * ]%) for High Pressure
      Receipt Point(s) shall be effective for the initial Contract Year. The
      applicable FL&U percentage shall be included in the calculation of
      Seller's Annual! Volume for the purposes of determining Seller's
      compliance with its delivery to Buyer of Seller's Annual Volume. Buyer
      shall recalculate the FL&U at the beginning of each Contract Year and

      B.4     
Allocation of Capacity, Notwithstanding any other term of this Agreement
if for any Day, Gatherer notifies Buyer that the capacity of its Gathering
System and/or Plant is constrained. Buyer shall cause Gatherer, without
liability to either Gatherer or Buyer, to allocate the available capacity as
follows:

    

    
      

    

    
      
        	
                
                

              	
                (a)

              	
                Capacity
      shall first be allocated pro rata to all Shippers with Guaranteed Capacity
      based upon the lower of their respective (i) Maximum Daily Quantities,
      (ii) Receipt Nominations or (iii) Confirmed Receipt Nominations;
      and

              

      

    

    
      

    

    
      
        	
              	
                (b)

              	
                Any
      remaining capacity shall be allocated pro rata to all Shippers with
      Non-Guaranteed Capacity based upon the lower of their respective (i)
      Maximum Daily Quantities, (ii) Receipt Nominations or (iii) Confirmed
      Receipt Nominations

              

      

    

    
       

    

    
      However,
if Gatherer can identify the location of the constraint, then Buyer shall cause
Gatherer, without liability to either Gatherer or Buyer, to impose such
allocation only upon those Shippers whose Gas is affected, and only at such
location. That capacity will then be allocated pro rata based on the previous 24
hour physical flow through the location that is constrained. From time to time,
Seller may request from Buyer or Gatherer information regarding daily volumes of
Gas received or to be received by the Gathering System to determine available
capacity and capacity allocation on the Gathering System,

    

    
      

    

    
      B.5       Access, Easements and
Rights-of-Way  Seller shall provide Buyer and/or Gatherer such

those rights under Seller's oil and Gas lease(s) to construct, operate, and
maintain pipelines and appurtenant facilities for the purpose of Gathering Gas
from the Area of Interest, Any grant to or use by Buyer or Gatherer as
contemplated above shall be for the express and limited purpose of gathering
Seller's gas from the Receipt Points or otherwise allowing Buyer to meeting its
obligations under this Agreement. Any other use shall be prohibited unless
approved in writing by Seller and appropriate surface owner.

Point Pressure Maintenance  Buyer shall cause Gatherer to use
reasonable efforts to maintain an average monthly operating pressure
of three hundred and fifty (350) psig or less (the "Target Pressure")
at the Low Pressure Receipt Point(s) into the Gathering System. Should the
average monthly pressure at any Low Pressure Receipt Point exceed the Target
Pressure for three (3) consecutive months for any Low Pressure Receipt Point,
then, beginning with the fourth month in which such average monthly pressure
exceeds the Target Pressure, Buyer shall reduce the Gathering and Processing Fee
by [ * ] ($[ * ]) per MMBtu. Buyer shall have nine (9) months in which
to install, or cause Gatherer to install, equipment necessary to reduce the
pressure at such Low Pressure Receipt Point to the Target Pressure. If Buyer or
Gatherer has not reduced the pressure at such Low Pressure Receipt Point after
such nine (9) month period to the Target Pressure, then Seller may, at its
option, upon thirty (30) Days' prior written notice to Buyer, release only the
affected Low Pressure Receipt Point and Seller's Gas delivered thereto from the
provisions of this Agreement   In the event of any such release,
during such thirty (30) Day period, Buyer and Seller shall negotiate in good
faith to reduce Seller's MDQ and Seller's Annual Volume by an amount equal to
the Gas that was projected to have been delivered to the affected Low Pressure
Receipt Point, and shall revise Exhibit F
accordingly.

      of the Gas shall be determined and calculated at least once each year by
      whomever is operating the CTM equipment, The component analysis and Gross
      Heating Value of the Gas shall be based on any of the following at the
      choice of the operator of the CTM equipment: spot samples, continuous
      samples, or on-line analysis  The component analysis of the Gas
      shall be performed by Gas chromatography in accordance with GPA 2261 or
      any pertinent revision(s) thereto or replacement(s) thereof. If the
      component percentages fall outside the limits of GPA 2261, then the
      operator of the CTM equipment shall make a reasonable judgment as to the
      accuracy of the component analysis. If neither Party objects in writing to
      the results within sixty (60) Days after their delivery, such results
      shall become conclusive. If either Party objects in writing to the results
      within sixty (60) Days after their delivery, then: in the case of spot
      samples, a re-sampling, redetermination and recalculation shall be
      performed by a third party acceptable to both Parties and such third
      party's results shall be used; and in the case of continuous samples or
      on-line analysis, the analyzer shall be tested for accuracy according to
      GPA 2261 and, if warranted, a recalculation of the components shall be
      made by a means acceptable to the Parties. The cost of any re-sampling,
      retesting, redetermination and/or recalculation shall be borne by the
      objecting Party.

      Any
dispute arising out of or relating to this Agreement shall be resolved in
accordance with the procedures specified in this Article i, which shall be the
sole and exclusive procedures for the resolution of any such
disputes   The Parties shall attempt in good faith to resolve any

controversy. Any Party may give the other Party written notice of any dispute
not resolved in the normal course of business. Within fifteen (15) Days after
delivery of the notice, the receiving Party shall submit to the other a written
response. The notice and the response shall include (a) a statement of each
Party's position and a summary of arguments supporting that position, and (b)
the name and title of the senior executive who will represent that Party and of
any other person who will accompany such executive. Within thirty (30) Days
after delivery of the disputing Party's notice, the designated senior executives
of both Parties shall meet at a mutually acceptable time and place, and
thereafter as often as they reasonably deem necessary, to attempt to resolve the
dispute. All reasonable requests for information made by one Party to the other
will be honored. All negotiations pursuant to this clause are confidential and
shall be treated as compromise and settlement negotiations for purposes of
applicable rules of evidence.

Days of the receiving Party's receipt of the disputing Party's notice, the
Parties shall endeavor to settle the dispute by mediation under the then-current
CPR Institute for Dispute Resolution mediation procedure in effect on the date
of this Agreement. Unless otherwise agreed, the Parties will select a mediator
from the CPR Panels of Distinguished Neutrals. Notwithstanding the provisions of
this clause, either Party may seek from any court having jurisdiction hereof any
interim, provisional or injunctive relief that may be necessary to protect its
rights or property or maintain the status quo before, during or after the
pendency of the mediation proceeding. The institution and maintenance of any
judicial action or proceeding for any such interim, provisional or injunctive
relief shall not constitute a waiver of the right or obligation of either Party
to submit the dispute to negotiation and mediation as described above, including
any claims or disputes arising from the exercise of such interim, provisional or
injunctive relief. If the dispute has not been resolved by mediation as provided
herein within ninety (90) Days of the initiation of the above procedures, either
Party may initiate litigation upon thirty (30) Days' written notice to the other
Party; provided, however, that if one Party has requested the other to
participate in any of the above non-binding procedures and the other has failed
to participate, the requesting Party may initiate litigation before expiration
of the above period. The prevailing Party in the resolution of any dispute
hereunder shall be entitled to have its costs and expenses incurred in the
prosecution of such dispute (including, without limitation, reasonable
attorneys' fees and expenses) reimbursed by the other Party promptly after the
resolution thereof
