    incorporated herein.

    For all natural gas service rendered hereunder, Shipper shall pay 
    Transporter each month the sum of the maximum charges listed below if 
    applicable:

         Reservation Charge - The Maximum Reservation Fee multiplied by Daily 
         Contract Quantity multiplied by the number of days in such month.  
         The Maximum Reservation Fee shall be subject to adjustment as 
         provided by Section 5 of this rate schedule.

         Commodity Charge - The Maximum Commodity Rate for Rate Schedule T-1 
         multiplied by the quantity of gas in Mcf received by Transporter for 
         Shipper in such month.

         Authorized Over-Run Charge - The Authorized Over-Run Rate multiplied 
         by the monthly volumes in excess of its Daily Contract Quantity as 
         defined in Section 6 of this rate schedule, received by Transporter 
         to Shipper or for its account during the billing month in questions.

         Annual Charge Adjustment - The Annual Charge Adjustment unit rate 
         multiplied by the quantity of gas in Mcf received to or for the

                      Transportation Service (continued)


5.  BILLING ADJUSTMENT FOR FAILURE TO TRANSPORT

    If, on any day during the month, Transporter fails to accept the quantity 
    of gas tendered by Shipper for transportation under this rate schedule on 
    such day up to Shipper's Daily Contract Quantity, and the gas so tendered 
    complies with and meets the provisions of this tariff with respect 
    thereto, the monthly charge otherwise computed shall be decreased by an 
    amount computed as the product of (a) and (b) below:

    (a)   the quantity in Mcf of gas tendered, but not accepted, up to, but 
          not exceeding, Shipper's Daily Contract Quantity;

    (b)   the Maximum Reservation Fee.


6.  SHIPPER'S DAILY CONTRACT QUANTITY

    Shipper's Daily Contract Quantity shall be the maximum quantity of natural 
    gas in Mcf which Transporter shall be obligated to receive from Shipper 
    (or for Shipper's account) at Shipper's Point of Receipt on any day for 
    transportation under this rate schedule.  Shipper's Daily Contract 
    Quantity shall be specified in the executed Service Agreement, in this 
    rate schedule.  Sheet No. 95 of this rate schedule constitutes an Index of 
    Daily Contract Quantities which are stated in the executed Service 
    Agreement.  However, the Daily Contract Quantities which are stated in the 
    executed Service Agreements shall not exceed the Daily Contract Quantities 
    which are stated in Sheet No. 95 as effective from time to time.

    Shipper shall have the right to tender on any day for transportation 
    volumes in excess of its Daily Contract Quantity, and Transporter shall 
    have the right, but shall not be obligated, to transport such excess 
    quantity on such day.  In the event, during any month, the quantity of gas 
    tendered for transportation and transported by Transporter for Shipper 
    exceeds a total quantity equal to the product of the number of days in the 
    month multiplied by Shipper's Daily Contract Quantity, then Shipper shall 
    pay for such monthly excess quantity of an additional amount equal to such 
    excess quantity in Mcf, multiplied by Authorized Over-Run Rate as stated 
    on Sheet No. 4 of this Tariff.

7.  OTHER ARRANGEMENTS BY SHIPPER

    It is the responsibility of Shipper to make any necessary arrangements 
    with other parties for further transportation of gas beyond Transporter's 
    Point of Delivery.  Shipper shall be obligated in any such arrangements to 
    provide for requisite dispatching and operating coordination with 
    Transporter.

8.  THERMAL BALANCING AND REDELIVERY QUANTITY

    Transporter undertakes to redelivery to Shipper at its Point of Delivery a 
    quantity of gas containing the gross heating value of gas received from 
    Shipper by Transporter at the Point of Receipt, less any attributable line 
    losses or unaccounted-for gas.

    The specific quantity in Mcf of gas to be redelivered by Transporter to 
    Shipper or for Shipper's account (herein referred to as Shipper's 
    "Redelivery Quantity") shall be determined each month as the product of 
    (a), (b), and (c) below:

    (a)   The volume of gas in Mcf tendered by Shipper to Transporter at the 
          Point of Receipt for transportation during the month.

    (b)   A fraction, the numerator of which is the measured volume of all gas 
          delivered by Transporter from its pipeline during the month, and the 
          denominator of which is the measured volume of all gas delivered to 
          Transporter during the month.

    (c)   A fraction, whose numerator is the average monthly unit heat content 
          of the gas tendered by Shipper to Transporter at the Point of 
          Receipt for transportation during the month, and whose denominator 
          is the average monthly unit heat content of the gas delivered by 
          Transporter to Shipper or for Shipper's account at the Point(s) of 
          Delivery during the month.  The unit heat content shall be as 
          defined in Section 1.9 of the General Terms and Conditions.  Average 
          monthly determinations of heat content shall be computed by 
          weighting for volumes delivered during the month.

    time at its sole discretion on a non-discriminatory basis, charges any 
    individual Shipper for transportation service under this rate schedule a 
    rate which is lower than such maximum Reservation Fee or Commodity rate; 
    provided, however, that such rates charged may not be less than the 
    minimum Reservation Fee or Commodity rate set forth on the currently 
    effective Sheet No. 4 of Transporter's FERC Gas Tariff.

    Transporter shall file with the Commission any and all reports as required 
    by the Commission's Regulations setting forth the applicable charge, the 
    individual Shipper(s) affected, the volume transported and any other

          designee to perform Shipper's obligations with regard to 
          nominations, scheduling and/or payment under this rate schedule, 
          provided that Shipper, such designee and Transporter shall agree in 
          writing that designee shall perform the specified obligation(s) of 
          Shipper and, with respect to any payment obligation, such designee 
          shall meet the creditworthiness provisions of this Rate Schedule.  
          Shipper shall not name more than one designee to perform each such 
          specified obligation under any Service Agreement hereunder.

          At Transporter's request, Shipper shall permit Transporter to name a 
          designee to perform Transporter's obligations with regard to 
          nominations, scheduling, billing, and/or receiving payment under

          specified obligation(s) of Transporter.  Transporter shall not name 
          more than one designee to perform each such specified obligation 
          under any Service Agreement hereunder.

5.  BILLING ADJUSTMENT FOR FAILURE TO TRANSPORT

    If, on any day during the month, Transporter fails to accept the quantity 
    of gas tendered by Shipper for transportation under this Rate Schedule on 
    such day up to the MDTQ, and the gas so tendered complies with and meets 
    the provisions of this tariff with respect thereto, the monthly 
    Reservation Charge otherwise computed shall be decreased by an amount 
    computed as the product of (a) and (b) below:

    (a)   The quantity in MMBtu of gas tendered, but not accepted, up to but 
          not exceeding the MDTQ;

    (b)   The Reservation Fee.

                    Firm Transportation Service (continued)



6.  MAXIMUM DAILY TRANSPORTATION QUANTITY

    Maximum Daily Transportation Quantity (MDTQ) shall be the maximum quantity 
    of natural gas in MMBtu which Transporter shall be obligated to receive 
    from Shipper (or for Shipper's account) at Shipper's Point of Receipt on 
    any day for transportation under this Rate Schedule.

    MDTQ shall be specified in the executed Service Agreement.

7.  AUTHORIZED OVER-RUN GAS

    Shipper shall have the right to tender on any day for transportation 
    volumes in excess of its MDTQ, and Transporter shall have the right, but 
    shall not be obligated, to transport such excess quantity on such day.  In 
    the event during any month, the quantity of gas tendered for 
    transportation and transported by Transporter for Shipper exceeds a total 
    quantity equal to the product of the number of days in the month 
    multiplied by MDTQ, such gas shall be defined as Authorized Over-run Gas.  
    Shipper shall pay for such monthly excess quantity, an additional amount, 
    equal to such excess quantity, in MMBtu, multiplied by the Authorized 
    Over-run Rate.

8.  OTHER ARRANGEMENTS BY SHIPPER

    It is the responsibility of Shipper to make any necessary arrangements 
    with other parties for further transportation of gas beyond Transporter's 
    Point of Delivery.  Shipper shall be obligated in any such arrangements to 
    provide for requisite dispatching and operating coordination with 
    Transporter.

9.  DETERMINATION OF RECEIPTS,THERMAL BALANCING AND REDELIVERY QUANTITY

    9.1   Determination of Receipts

          For purposes of this section "overage" shall be defined as Scheduled 
          Receipts in excess of actual quantities received, and "underage" 
          shall be defined as Scheduled Receipts below actual quantities 
          received.  In the event actual quantities received by Transporter do 
          not equal the Scheduled Receipts for such point, any overage or 
          underage shall be allocated as follows:

          (1)   To the extent Transporter has entered into an Operational 
                Balancing Agreement ("OBA") as set forth below which covers 
                the point of receipt, any overages or underages at such point 
                of receipt shall not be allocated to Shippers, but shall be 
                resolved in accordance with the OBA;

                               RATE SCHEDULE FTS
                    Firm Transportation Service (continued)


          (2)   To the extent there is not an OBA for the subject receipt 
                point, Transporter and the interconnecting party will agree as 
                to which party is responsible for the predetermined allocation 
                (PDA), and if the party has agreed to submit the PDA, 
                Transporter shall allocate underages or overages in accordance 
                with the PDA;

          (3)   To the extent there is no OBA or PDA, Transporter shall 
                allocate any overage or underage pro-rata based on scheduled 
                and confirmed quantities at the receipt point.

          (4)   The responsibility for calculation and reporting of allocated 
                quantities should rest with the party responsible for 
                accepting NAESB allocation types.  The party receiving 
                nominations should provide allocation statements.


    A.    Operational Balancing Agreement (OBA)

          (1)   An OBA is a contract between two parties which specifies the 
                procedures to manage operating variances at an interconnect.  
                Transporter is willing to negotiate and execute Operational 
                Balancing Agreements (OBAs) with appropriate parties that 
                operate natural gas facilities which interconnect with 
                Transporter's system.  Such OBAs will provide that any 
                variance between actual quantities and scheduled and confirmed 
                quantities for any day shall be resolved in-kind promptly or 
                cashed-out pursuant to the terms of the OBAs.

          (2)   To the extent actual receipts vary from scheduled receipts at 
                a point of receipt for which Transporter has entered into an 
                OBA, Shippers utilizing such point of receipt shall be 
                responsible for any charges incurred by Transporter under the 
                OBA.

    B.    Predetermined Allocation Statements (PDA)

          As a minimum, allocations should be provided by both contract and 
          location. The upstream or downstream party providing the point 
          confirmation should submit the pre-determined allocation to the 
          allocating party after or during confirmation and before the start 
          of the gas day. The types of allocation methodologies is a list from 
          which two parties may agree.  If the two parties can not agree upon 
          an allocation methodology, pro rata based upon confirmed nominations 
          should be used as the default method.  The party responsible for 
          custody transfer (the party performing the measurement function) 
          should provide the allocation.   The PDA methods shall include 
          ranked, pro rata, percentage, swing, and operator provided value, as 
          such terms are used in the NAESB Standards.  The same standard 
          allocation methodologies should be available for use at all points, 
          except those covered by an OBA.  A new allocation detail may be 
          needed when a nomination changes.

                               RATE SCHEDULE FTS
                    Firm Transportation Service (continued)



                Transporter shall be entitled to rely exclusively on an 
                effective PDA in allocating gas received at a point and the 
                interconnect party holds Transporter harmless against actions 
                taken and allocations made in reliance upon such PDA.  No 
                retroactive changes to a PDA may be made unless Transporter 
                and all affected parties agree in writing.  The allocating 
                party should send back "confirmation" of receipt of the pre-
                determined allocation within 15 minutes.

    9.2   THERMAL BALANCING AND REDELIVERY QUANTITY

          Transporter shall undertake to redeliver to Shipper at its Point of 
          Delivery a quantity of gas containing the gross heating value of gas
================================================================================


                               RATE SCHEDULE FTS
                    Firm Transportation Service (continued)



    received from Shipper by Transporter at the Point of Receipt, plus or 
    minus any attributable line losses or unaccounted-for gas.

    The specific quantity in MMBtu of gas to be redelivered by Transporter to 
    Shipper or for Shipper's account (herein referred to as Shipper's 
    "Redelivery Quantity") shall be determined each month as the product of 
    (a) and (b) below:

    (a)   The volume of gas in MMBtu received by Transporter from Shipper at 
          the Point of Receipt for transportation during the month.

    (b)   A fraction, the numerator of which is the measured volume in MMBtu 
          of all gas delivered by Transporter from its pipeline during the 
          month, and the denominator of which is the measured volume in MMBtu 
          of all gas received by Transporter during the month.

    Scheduling on a daily basis shall reflect the general procedures 
    identified above. The timing for reporting daily operational allocations 
    after the gas has flowed is within one business day after the end of the 
    gas day.  If the best available data for reporting daily operational 
    allocations is the scheduled quantity, that quantity should be used for 
    the daily operational allocation.  Precise balancing shall be on a monthly 
    basis.  Any imbalances during a particular month shall be kept to the 
    minimum permitted by operating conditions and cashed-out consistent with 
    Section 21.2 of the General Terms and Conditions of Transporter's FERC Gas 
    Tariff.  Imbalance statements should be generated at the same time or 
    prior to the generation of the transportation invoice. The imbalance 
    statement should be rendered prior to or with the invoice, and the 
    transportation invoice should be prepared on or before the 9th business 
    day after the end of the production month.  Rendered is defined as 
    postmarked, time-stamped, and delivered to the designated site.

    Delivery point allocations should be performed at the lowest level of 
    detail provided by nominations.  The determination of deliveries 
    applicable to Shipper shall be made in accordance with the thermal 
    balancing provisions above unless a PDA in accordance with the PDA 
    provision below or an operating arrangement satisfactory to Shipper, 
    Transporter and any third party transporting to or from Transporter's 
    system is submitted. The responsibility for calculation and reporting of 
    allocated quantities should rest with the party responsible for accepting 
    NAESB allocation types.  The party receiving nominations should provide 
    allocation statements. The upstream or downstream party providing the 
    point confirmation should submit the pre-determined allocation to the 
    allocating party after or during confirmation and before the start of the 
    gas day.  To the extent there is no OBA or PDA, Transporter shall allocate 
    deliveries pro rata based on confirmed quantities. As a minimum, 
    allocations should be provided by both contract and location.  The types 
    of allocation methodologies is a list from

                    Firm Transportation Service (continued)


    which two parties may agree.  If the two parties can not agree upon an 
    allocation methodology, pro rata based upon confirmed nominations should 
    be used as the default method.  The party responsible for custody transfer 
    (the party performing the measurement function) should provide the 
    allocation.  The PDA methods shall include ranked, pro rata, percentage, 
    swing, and operator provided value, as such terms are used in the NAESB 
    Standards. The same standard allocation methodologies should be available 
    for use at all points.  A new allocation detail may be needed when a 
    nomination changes.  Transporter shall be entitled to rely exclusively on 
    an effective PDA in allocating gas delivered to a point.  No retroactive 
    changes to a PDA may be made unless Transporter and all affected parties 
    agree in writing. The allocating party should send back "confirmation" of 
    receipt of the pre-determined allocation within 15 minutes.  A Party may 
    change the PDA during a calendar month provided (i) such change will have 
    prospective effect only, (ii) all Shippers on Transporter's system with 
    scheduled deliveries at such point have been notified of the change and 
    the effective date of the change, and (iii) the interconnecting party 
    identifies and holds Transporter and Shippers utilizing such points 
    harmless against actions taken and allocations made in reliance upon such 
    change in PDA.

            transportation under this rate schedule.

2.    APPLICABILITY AND CHARACTER OF SERVICE

      This rate schedule shall apply to all gas transported by Transporter 
      for Shipper under this rate schedule.

      Service rendered by Transporter for Shipper under this rate schedule 
      shall consist of the receipt of gas by Transporter from or for the 
      account of Shipper at Shipper's Point(s) of Receipt and the 
      transportation and delivery of such gas to or for the account of 
      Shipper at the Point(s) of Delivery, as such Point(s) of Receipt and 
      Delivery are contained in the executed Service Agreement.

      Transportation service rendered by Transporter to Shipper under this 
      rate schedule shall be subject to curtailment or interruption in order 
      for Transporter to meet its firm service obligations and as provided in 
      Sections 8 (Force Majeure) and 9 (Scheduling and Curtailment) of the 
      General Terms and Conditions.

      Gas received for transportation hereunder will be commingled with other 
      gas in Transporter's system, and the specific gas made available by 
      Shipper or for Shipper's account for transportation may not be the same 
      gas delivered to Shipper or for its account.

3.    RATES

      The applicable rates for service under this rate schedule are set forth 
      on the currently effective Sheet No. 4 of this tariff and are hereby 
      incorporated herein.

      For all natural gas service rendered hereunder, Shipper shall pay 
      Transporter each month the sum of the charges listed below if 
      applicable:

            Commodity Charge - The Commodity Rate multiplied by the quantity 
            of gas in MMBtu received by Transporter for Shipper in such month.

            Annual Charge Adjustment - The Annual Charge Adjustment unit rate 
            multiplied by the quantity of gas in MMBtu received to or for the 
            account of Shipper by Transporter during the billing month in 
            question.

            Incidental Charges - Shipper shall reimburse Transporter for 
            incidental charges incurred by Transporter in providing this 
            service.  Such charges may include only: (i) reporting or filing 
            fees, (ii) costs of construction or acquisition of new facilities 
            necessary to render service, to the extent agreed to by 
            Transporter and Shipper, and (iii) other such charges as may be 
            authorized by the Commission.  Transporter shall not recover any 
            charges recovered under this paragraph in a Natural Gas Act 
            Section 4 rate proceeding.

            Transporter shall charge the maximum Commodity Rate set forth on 
            Sheet No. 4 unless Transporter, from time to time and at any time 
            at its sole discretion on a non-discriminatory basis, charges any 
            individual Shipper for transportation service under this Rate 
            Schedule a rate which is lower than such maximum Commodity rate; 
            provided, however, that such Commodity Rate charged may not be 
            less than the minimum Commodity rate set forth on the currently 
            effective Sheet No. 4 of Transporter's FERC Gas Tariff.

7.    DETERMINATION OF RECEIPTS, THERMAL BALANCING AND REDELIVERY QUANTITY 

7.1   Determination of Receipts:

      For purposes of this section "overage" shall be defined as Scheduled 
      Receipts in excess of actual quantities received, and "underage" shall 
      be defined as Scheduled Receipts below actual quantities received. In 
      the event actual quantities received by Transporter do not equal the 
      scheduled receipts for such point, any overage or underage shall be 
      allocated as follows:

          (1)   To the extent Transporter has entered into an Operational 
                Balancing Agreement as set forth below which covers the point 
                of receipt, any overages or underages at such point of receipt 
                shall not be allocated to Shippers, but shall be resolved in 
                accordance with the OBA:

           (2)  to the extent there is not a OBA for the subject receipt 
                point, Transporter and the interconnecting Party will agree as 
                to which party is responsible for the predetermined allocation 
                (PDA) and if the party has agreed to submit the PDA, 
                Transporter shall allocate underages or overages in accordance 
                with the PDA;

           (3)  To the extent there is no OBA or PDA, Transporter shall 
                allocate any overage or underage pro-rata based on scheduled 
                and confirmed quantities at the receipt point.

           (4)  The responsibility for calculation and reporting of allocated 
                quantities should rest with the party responsible for 
                accepting NAESB allocation types.  The party receiving 
                nominations should provide allocation statements.

         A. Operational Balancing Agreement (OBA)

            (1) An OBA is a contract between two parties which specifies the 
                procedures to manage operating variances at an interconnect.  
                Transporter is willing to negotiate and execute Operational 
                Balancing Agreements (OBAs) with appropriate parties that 
                operate natural gas facilities which interconnect with 
                Transporter's system.  Such OBAs will provide that any 
                variance between actual quantities and scheduled and confirmed 
                quantities for any day shall be resolved in kind promptly or 
                cashed-out pursuant to the terms of the OBAs. 

         B. Predetermined Allocation Statements (PDA)

            The upstream or downstream party providing the point confirmation 
     should submit the pre-determined allocation to the allocating party after 
     or during confirmation and before the start of the gas day. As a minimum, 
     allocations should be provided by both contract and location.
================================================================================



                               RATE SCHEDULE ITS
               Interruptible Transportation Service (continued)

            The types of allocation methodologies is a list from which two 
            parties may agree.  If the two parties can not agree upon an 
            allocation methodology, pro rata based upon confirmed nominations 
            should be used as the default method.  The party responsible for 
            custody transfer (the party performing the measurement function) 
            should provide the allocation.  The PDA methods shall include 
            ranked, pro rata, percentage, swing, and operator provided value, 
            as such terms are used in the NAESB Standards. The same standard 
            allocation methodologies should be available for use at all points 
            except those covered by an OBA.  A new allocation detail may be 
            needed when a nomination changes.  Transporter shall be entitled 
            to rely exclusively on an effective PDA in allocating as received 
            at a point taken and allocations made in reliance upon such PDA.  
            No retroactive  changes to a PDA may be made unless Transporter 
            harmless against actions taken and allocations made in reliance 
            upon such PDA.  No retroactive changes to a PDA may be made unless 
            Transporter and all affected parties agree in writing. The 
            allocating party should send back "confirmation" of receipt of the 
            pre-determined allocation within 15 minutes.

7.2   THERMAL BALANCING AND REDELIVERY QUANTITY

     Transporter shall undertake to redeliver to Shipper at its Point of 
     Delivery a quantity of gas containing the gross heating value of gas 
     received from Shipper by Transporter at the Point of Receipt, less any 
     attributable line losses or unaccounted-for gas.

    The specific quantity in MMBtu gas to be redelivered by Transporter to 
    Shipper or for Shipper's account (herein referred to as Shipper's 
    "Redelivery Quantity") shall  be determined each month as the product of 
    (a), and (b) below:

    (a)  The volume of gas in MMBtu received by Transporter from Shipper at 
         the Point of Receipt for transportation during the month.

    (b)  A fraction, the numerator of which is the measured volume in MMBtu of 
         all gas delivered by Transporter from its pipeline during the month, 
         and the denominator of which is the measured volume in MMBtu of all 
         gas received by Transporter during the month.

     Scheduling on a daily basis shall reflect the general procedures 
     identified above. The timing for reporting daily operational allocations 
     after the gas has flowed is within one business day after the end of the 
     gas day.  If the best available data for reporting daily operational 
     allocations is the scheduled quantity, that quantity should be used for 
     the daily operational allocation.  Precise balancing shall be on a 
     monthly basis. Any imbalances during a particular month shall be kept to 
     the minimum permitted by operating conditions and cashed-out consistent 
     with Section 21.2 of the General Terms and Conditions of Transporter's 
     FERC Gas Tariff.

                               RATE SCHEDULE ITS
               Interruptible Transportation Service (continued)

     Imbalance statements should be generated at the same time or prior to the 
     generation of the transportation invoice. The imbalance statement should 
     be rendered prior to or with the invoice, and the transportation invoice 
     should be prepared on or before the 9th business day after the end of the 
     production month.  Rendered is defined as postmarked, time-stamped, and 
     delivered to the designated site.

     Delivery point allocations should be performed at the lowest level of 
     detail provided by nominations.  The determination of deliveries 
     applicable to Shipper shall be made in accordance with the thermal 
     balancing provisions above unless a PDA in accordance with the PDA 
     provision below or an operating arrangement satisfactory to Shipper, 
     Transporter and any third party transporting to or from Transporter's 
     system is submitted.  The responsibility for calculation and reporting of 
     allocated quantities should rest with the party responsible for accepting 
     NAESB allocation types.  The party receiving nominations should provide 
     allocation statements.

     The upstream or downstream party providing the point of confirmation 
     should submit the pre-determined allocation to the allocating party after 
     or during confirmation and before the start of the gas day. To the extent 
     there is no OBA or PDA, Transporter shall allocate pro rata based on 
     confirmed nominations.  As a minimum, allocations should be provided by 
     both contract and locations. The types of allocation methodologies is a 
     list from which two parties may agree.  If the two parties can not agree 
     upon an allocation methodology, pro rata based upon confirmed nominations 
     should be used as the default method.  The party responsible for custody 
     transfer (the party performing the measurement function) should provide 
     the allocation. The same standard allocation methodologies should be 
     available for use at all points.  A new allocation detail may be needed 
     when a nomination changes. The PDA methods shall include ranked, pro 
     rata, percentage, swing, and operator provided value,  as such terms are 
     used in the NAESB Standards.  Transporter shall be entitled to rely 
     exclusively on an effective PDA in allocating gas delivered to a point.  
     No retroactive changes to a PDA may be made unless Transporter and all 
     affected parties agree in writing.  The allocating party should send back 
     "confirmation" of receipt of the pre-determined allocation within 15 
     minutes.

     A Party may change the PDA during a calendar month provided (i) such 
     change will have prospective effect only, (ii) all Shippers on 
     Transporter's system with scheduled deliveries at such point have been 
     notified of the change and the effective date of the change, and (iii) 
     the interconnecting Party identifies and holds Transporter and Shippers 
     utilizing such points harmless against actions taken and allocations made 
     in reliance upon such change in PDA.

================================================================================

                         GENERAL TERMS AND CONDITIONS
                                  (continued)

      Notwithstanding any other provision herein, Shipper may deliver at 
      Transporter's Receipt Points gas that does not meet the quality 
      specifications contained in 2.1(a) through (h) above, inclusive, so long 
      as Transporter is satisfied that the blended gas stream at all Delivery 
      Points meets the quality specifications, and so long as the safety and 
      reliability of Transporter's system is not impaired, in Transporter's 
      sole opinion, exercised in good faith; provided, however, if the blended 
      gas stream at all Delivery Points does not meet the quality 
      specifications or the safety and reliability of Transporter's system is 
      impaired, in Transporter's sole opinion, exercised in good faith, 
      Transporter will notify Shipper of such deficiency and if Shipper fails 
      to remedy such deficiency promptly, the gas at the Receipt Point(s) most 
      out of compliance with the quality specification shall be shut-in until 
      the blended gas stream at the Delivery Point(s) meets the quality 
      specification; and, if more than one Receipt Point is equally out of 
      compliance, the shut-in shall be pro-rata as to those Receipt Points; 
      provided further, that nothing herein shall restrict Transporter's right 
      to refuse to accept further receipt of gas tendered for delivery to 
      Transporter by Shipper which fails at any time to conform to the quality 
      specifications in 2.1(a) through (h) above if the safety and reliability 
      of Transporter's system is impaired, in Transporter's sole opinion 
      exercised in good faith.

2.2   Quality Tests:

      (a)  The quality specifications of the gas delivered hereunder shall be 
           determined by tests which Transporter shall cause to be made at 
           each receipt and delivery point.

      (b)  The heating value of the gas delivered shall be calculated from a 
           chromatographic analysis of a representative gas sample collected 
           daily during the month, or any other method mutually agreed upon.  
           Such chromatographs shall be owned, operated, and maintained by 
           Transporter at Representative locations on Transporter's system, or 
           as agreed upon.

      (c)  Tests shall be made to determine the total sulpher, hydrogen 
           sulfide, carbon dioxide, nitrogen and oxygen content of the gas, by 
           approved standard methods in general use in the gas industry, and 
           to determine the hydrocarbon dewpoint and water vapor content of 
           such gas by methods satisfactory to the parties.  Tests shall be 
           made frequently enough to assure that the gas is conforming 
           continuously to the quality requirements.  Transporter shall have 
           the right to require Shipper to have remedied any deficiency of the 
           gas in quality and, in the event such deficiency is not remedied,
================================================================================


                         GENERAL TERMS AND CONDITIONS
                                  (continued)


                the right, in addition to all other remedies available to it 
                by law, to refuse to accept such deficient gas from Shipper 
                until such deficiency is remedied.

3.  MEASURING EQUIPMENT

    3.1   Installation:  At each Point of Receipt or Delivery all measuring 
          equipment, devices and materials shall be furnished and installed, 
          owned, maintained and operated as mutually agreed by the parties; 
          provided, however, that Transporter may require, at its option, that 
          Shipper bear the expense of furnishing and installing such equipment 
          devices and materials in any instance in which such Shipper requests 
          a new or additional Point of Delivery or Receipt for such Shipper's 
          convenience.  Shipper may install and operate check measuring 
          equipment at its expense provided such installation and operation 
          does not interfere with the use of Transporter's equipment.

    3.2   Accessibility:  Shipper shall provide or cause to be provided to 
          Transporter, free of charge, sufficient space on the platforms 
          designated as Points of Receipt on Appendix A for the Executed 
          Service Agreement for Transporter to install and access by 
          helicopter or boat its measurement facilities.

    3.3   Testing Meter Equipment:  The accuracy of Transporter's measuring 
          equipment shall be verified by test, at no more than forty-five (45) 
          day intervals and at other times upon request of the Shipper.  No 
          less than 72 hours notice of the time and nature of the test shall 
          be given by Transporter to permit convenient arrangement for the 
          presence of Shipper's representative.  If, after notice, the Shipper 
          fails to have a representative present, the results of the test 
          shall nevertheless be considered accurate until the next test.  If 
          any of the measuring equipment is found to be registering 
          inaccurately in any percentage, it shall be adjusted at once to read 
          as accurately as possible.  All tests of such
================================================================================


                         GENERAL TERMS AND CONDITIONS
                                  (continued)

          measuring equipment shall be made at the expense of Transporter, 
          except that the Shipper shall bear the expense of additional tests 
          made at its request if the inaccuracy is found to be two percent 
          (2%) or less.

    3.4   Correction and Adjustment:  If at any time any of the measuring 
          equipment is registering inaccurately by an amount less than two 
          percent (2%), previous readings shall be considered correct.  If the 
          inaccuracy exceeds two percent (2%) at a reading corresponding to 
          the average hourly rate of flow, the previous readings of such 
          equipment shall be corrected to zero error for any inaccurate period 
          definitely known or agreed upon, or if not so known or agreed upon, 
          for a period of one-half (1/2) of the elapsed time since the last 
          test not to exceed a correction period of thirty (30) days.  If the 
          measuring equipment is out of service, the volume of gas delivered 
          during such period shall be determined:

          (a)   By using the data recorded by any check measuring equipment 
                accurately registering; or

          (b)   If such check measuring equipment is not registering 
                accurately, but the percentage of error is ascertainable by a 
                calibration test, by using the data recorded, corrected to 
                zero error; or

          (c)   If neither of the methods provided in (a) and (b) above can be 
                used, by estimating the quantity delivered by reference to 
                deliveries under similar conditions during a period when the 
                equipment was registering accurately.

4.  MEASUREMENT BASE

    4.1   Metering:  The gas shall be metered by one or more of the following:  
          orifice, displacement or turbine type meters, at the discretion of 
          Transporter.  When orifice meters are used, they shall be
================================================================================


                         GENERAL TERMS AND CONDITIONS
                                  (continued)

          installed and maintained, and volumes shall be measured in 
          accordance with the methods prescribed in "Orifice Metering of 
          Natural Gas", ANSI/API 2530, including the Appendix thereto, as 
          published December 1985, or any subsequent revision thereof 
          acceptable to both parties.  If turbine meters are used, they shall 
          be installed and operated in accordance with American Gas 
          Association Transmission Measurement Committee Report No. 7.  When 
          displacement meters are used, the number of Mcf delivered hereunder 
          shall be computed by including factors for pressure, temperature and 
          deviation from Boyle's Law.

    4.2   Deviation from Ideal Gas Laws:  Correction shall be made for 
          deviation of the gas from Boyle's Law at the pressure and 
          temperature at which the gas is metered.  To determine the factors 
          for such correction, a quantitative analysis of the gas shall be 
          agreed upon by both parties or by computations made in accordance 
          with NX-19 of the American Gas Association and any modifications and 
          amendments thereof applied in a practical manner.

    4.3   Specific Gravity:  The specific gravity of the gas delivered shall 
          be calculated from a chromatographic analysis of a representative 
          gas sample collected daily during the month, or any other method 
          mutually agreed upon.  Such chromatographs shall be owned, operated, 
          and maintained by transporter at representative locations on 
          Transporter's system, or as agreed upon.

    4.4   Flowing Temperature:  The flowing temperature of the gas being 
          metered shall be determined by means of a recording thermometer of a 
          type acceptable to both parties, installed and maintained in 
          accordance with the specifications set forth in said ANSI/API 2530.  
          The arithmetical average of readings each day for time that gas is 
          flowing shall be deemed the gas temperature and used in computing 
          the volumes of gas metered during such day.

                         GENERAL TERMS AND CONDITIONS
                                  (continued)

    4.5   Measurement:  The Unit of Measurement for gas delivered or 
          redelivered hereunder shall be one thousand (1,000) cubic feet, (one 
          [1] Mcf) of gas at a base temperature of sixty degrees (60) 
          Fahrenheit and at a base pressure of fourteen and seventy-three 
          hundredths (14.73) pounds per square inch absolute.

    4.6   New Measurement Techniques:  If at any time during the term hereof, 
          a new method or technique is developed with respect to gas 
          measurement, such new method or technique may be substituted for the 
          gas measurement set forth in this Section upon mutual agreement 
          thereto by the Parties.

5.  INSPECTION OF EQUIPMENT AND RECORDS

    5.1   Inspection of Equipment and Data:  Each party shall have the right 
          to inspect equipment installed or furnished by the other, and the 
          charts and other measurement or test data of the other, at all times 
          during business hours; but the reading, calibration and adjustment 
          of such equipment and changing of charts shall be done only by the 
          party installing or furnishing same.  Unless the parties otherwise 
          agree, each party shall preserve all original test data, charts and 
          other similar records in such party's possession, for a period of at 
          least three (3) years.

    5.2   Information for Billing:  When information necessary for billing by 
          Transporter is in the control of Shipper, Shipper shall furnish the 
          actual information to Transporter on or before the fifth (5th) 
          working day of the month following the billing month.

          Monthly Measurement.  Transporter shall include any corrections 
          received on or before five (5) working days after the month in 
          preparation of monthly measurement statements.  Measurement data 
          available upstream of aggregated points should be sent to the 
          allocating party and used to allocate the aggregated volume back to 
          the upstream points.  The monthly measurement set will serve as the 
          basis upon which allocations are performed. For treatment of 
          measurement prior period adjustments, treat the adjustment by taking 
          it back to the production month.  A meter adjustment becomes a prior 
          period adjustment after the fifth business day following the 
          business month. Transporter shall process prior period adjustments 
          within six (6) months of the monthly measurement for the respective 
          month, subject to an additional three (3) month period for an 
          affected party, including Transporter, to challenge any prior period 
          adjustment.  Such processing limitations shall not apply in the case 
          of deliberate omission or misrepresentation to limit Shipper's or 
          Transporter's other statutory or contractual rights.  To the extent 
          an interconnecting party is contractually or statutorily permitted to process adjustments beyond the six (6) month period above, Transporter shall be permitted to process such corresponding adjustments to Shippers.

                                  (continued)


    5.3   Verification of Computations:  Each party shall have the right to 
          examine at reasonable time the books, records and charts of the 
          other to the extent necessary to verify the accuracy of any 
          statement, charge or computation made pursuant to these General 
          Terms and Conditions and to the Rate Schedules to which they apply.

                                  (continued)

6.  BILLING AND PAYMENTS

    6.1   Billing:  On or before the tenth (10th) day of each month, 
          Transporter shall render to each Shipper a bill for the actual 
          service rendered during the immediately preceding month ("billing 
          month") if actual data is available.  All statements should be 
          standardized to the same level of detail.  The specific minimum 
          level of detail on invoice, remittance and statement of an account 
          should be guided by the development of data elements.  If actual 
          data is not available, billing will be on an estimated basis and 
          such estimate will be corrected to actual tools on the billing 
          immediately following receipt by Transporter of such actual data.  
          Bills will utilize the descriptions and charge codes set forth in 
          the NAESB Standards.  Transportation bills shall specify all rate 
          components, and shall separately state the net billing rate and any 
          discount, if applicable, and any prior period adjustments.  Prior 
          period adjustments are reported by production date, but they do not 
          have to be invoiced separately by production month - nor is each 
          production month a separate paper invoice page.  Required invoice 
          backup data should accompany or precede this invoice.  Regarding 
          inadequate detail, supporting documentation should be provided upon 
          request, with timing of supporting documentation to follow the 
          timing of the flowing gas transactions.

    6.2   Payment:  Within ten (10) calendar days after the date of receipt of 
          billing invoice, or the next business day in the event the tenth 
          (10th) day is a weekend or bank holiday, Shipper shall provide any 
          supporting documentation, including invoice number(s), and shall pay 
          Transporter by check, or by wire transfer of federal funds, the 
          amount of the bill rendered by Transporter for the billing month in 
          accordance with Section 6.1.  For purposes of this Section, the date 
          of receipt of billing invoice is deemed to be three (3) days after 
          the postmark date.  Any payment shall be considered to have been 
          made on the date such payment is transferred by Shipper to the 
          address designated by Transporter.  If presentation of a bill by 
          Transporter is delayed after the due date, then the time for payment 
          shall be extended correspondingly unless Shipper is responsible for 
          such delay.  If Shipper has notified Transporter in writing of an 
          error in invoice during the period for which a genuine dispute 
          exists as to the alleged error, Shipper shall pay the portion of the 
          invoiced amount which is not in dispute and shall provide 
          documentation identifying the basis for the dispute.

                         GENERAL TERMS AND CONDITIONS
                                  (continued)



    6.3   Interest on Unpaid Amounts:  Should Shipper fail to pay the amount 
          of any bill rendered by Transporter when such amount is due, 
          interest shall accrue thereon at a rate of interest equal to the 
          then effective rate computed in the manner set forth in the 
          Commission's Regulations.

    6.4   Remedies for Failure to Pay:  If such failure to pay continues for 
          thirty (30) days after payment is due, Transporter, in addition to 
          any other remedy it may have, may suspend gas transportation service 
          with ten (10) days notice until such amount, including interest, is 
          paid unless Shipper in good faith disputes the amount owing and pays 
          or provides guarantee of payment of all amounts not subject to such 
          good faith dispute.

    6.5   Statement of Account.  Transporter shall provide Shipper with a 
          detailed Statement of Account in accordance with the NAESB 
          Standards, which statement shall indicate any outstanding amounts by 
          invoice.

                                  (continued)


    6.6   Adjustment of Billing Error:  In the event an error is discovered in 
          any bill rendered by Transporter, the amount of such error shall be 
          adjusted within thirty (30) days after discovery, provided that 
          claim therefore shall have been made within six (6) months from the 
          date such bill was rendered subject to an additional three (3) month 
          period for an affected party to challenge the error.  Such 
          processing limitations shall not apply in the case of deliberate 
          omission or misrepresentation or mutual mistake of fact.  Nothing 
          herein shall be construed to limit Shipper's or Transporter's other 
          statutory or contractual rights.  To the extent an interconnecting 
          party is contractually or statutorily permitted to process 
          adjustments beyond the six (6) month period above, Transporter shall 
          be permitted to process such corresponding adjustments to Shippers.

7.  NOTICE OF CHANGES IN OPERATING CONDITIONS

    Transporter and Shipper shall notify each other from time to time as 
    necessary of expected changes in the rates of delivery or receipt of gas, 
    or in the pressures or other operating conditions, and the reason for such 
    expected changes, to the end that the other party may be prepared to meet 
    them when they occur.

8.  FORCE MAJEURE

    8.1   If either party shall fail to perform any obligation imposed upon it 
          by these General Terms and Conditions or by an executed Service 
          Agreement, and such failure shall be caused, or materially 
          contributed to, by:  any acts of God; strikes; lockouts; or other 
          industrial disturbances; act of public enemies; sabotage; wars; 
          blockades; insurrections; riots; epidemics; landslides; lightening; 
          earthquakes; floods; storms; fires; washouts; arrests and restraints 
          of rulers and peoples; civil disturbances; explosions; breakage of 
          or accident to machinery or lines of pipe, materials or equipment; 
          the failure of any of Shipper's gas suppliers to delivery gas, or 
          failure of Shipper to receive gas, in accordance with its 
          obligations if such failure
================================================================================

                         GENERAL TERMS AND CONDITIONS
                                  (continued)

          is occasioned by an event or occurrence of the character described 
          in this Section as constituting force majeure; any legislative, 
          administrative or judicial action which has been resisted in good 
          faith by all reasonable legal means; any act of omission whether of 
          the kind herein enumerated or otherwise not within the control of 
          the party invoking this Section and which by the exercise of due 
          diligence such party could not have prevented, or shall be 
          occasioned by the necessity for making repairs to or reconditioning 
          machinery, equipment, or pipelines, not resulting from the fault or 
          negligence of such party; such failure shall be deemed not to be a 
          breach of the obligation of such party, but such party shall use 
          reasonable diligence to put itself in a position to carry out its 
          obligations. Nothing contained herein shall be construed to require 
          either party to settle a strike or lockout by acceding against its 
          judgment to the demands of the opposing parties.

    8.2   No such cause affecting the performance of either party shall 
          continue to relieve such party from its obligation after the 
          expiration of a reasonable period of time within which by the use of 
          due diligence such party could have remedied the situation 
          preventing its performance, nor shall any such cause relieve either 
          party from any obligation unless such party shall give notice 
          thereof in writing to the other party with reasonable promptness; 
          and like notice shall be given upon termination of such cause.

9.  NOMINATIONS, CONFIRMATION, SCHEDULING AND CURTAILMENT

    9.1   Nomination:
          A.   General
               Quantities nominated and scheduled shall be reflected in MMBtu.  
               Unless otherwise agreed to by Transporter, Shipper shall 
               nominate in writing to Transporter's Gas Management and Control 
               Department the following information:
               (1) The contract number under which service is being nominated;
               (2) The quantity in dekatherms per day of gas to be tendered at 
                   each receipt point;
               (3) The quantity in dekatherms per day of gas to be tendered at 
                   each receipt point;
               (4) The term of the nomination.  All nominations should be 
                   considered original nominations and should be replaced to 
                   be changed.
               (5) A receipt and delivery rank for each upstream and 
                   downstream party can be submitted by Shipper.  This will be 
                   used when making reductions during the scheduling process.
================================================================================

                         GENERAL TERMS AND CONDITIONS
                                  (continued)

              The total receipt nominations must equal the total delivery 
              nominations, with the exception of quantities nominated to 
              correct an imbalance.

              A package ID is a way to differentiate between discrete business 
              transactions.  When used, Package ID should be supported for 
              nominating, scheduling, allocating, and invoicing (sales and 
              purchase), and not required for transportation invoicing.  Use 
              of the Package ID is at the discretion of the service requester, 
              and if sent, should be accepted and processed by the service 
              provider.

              If Shipper fails to comply with provisions (1) through (4) of 
              this Section 9.1.A, Transporter shall not schedule the 
              commencement of service or change to a prior nomination.  
              Transporter supports a seven-days-a-week, twenty-four-hours-a-
              day nominations process.  It is recognized that the success of 
              seven-days-a-week, twenty-four-hours-a-day nominations process 
              is dependent on the availability of affected parties scheduling 
              personnel on a similar basis.  Party contacts need not be at 
              their ordinary work sites, but should be available by beeper.

              Overrun quantities must be scheduled as a separate transaction.

         B.   Nomination Timeline

              Transporter and Shipper shall support the following minimum 
              NAESB standard nomination cycles as set forth below in (1) and 
              (2).  Such nomination opportunities shall represent the grid-
              wide synchronization times across the North American pipeline 
              network.

                         GENERAL TERMS AND CONDITIONS
                                  (continued)

              There is no limitation as to the number of intraday nominations 
              which a Shipper may submit at any one standard nomination cycle 
              or in total across all standard nomination cycles. Intraday 
              nominations will be effective for a single gas day, and will not 
              remain in effect for prospective gas days.  There is no need to 
              renominate if intraday nomination modifies existing nomination.  
              Intraday nominations must have a beginning and ending time.  To 
              the extent, a Shipper submits an intraday nomination which 
              specifies an effective term of longer than one day, Transporter 
              shall make the nomination effective for the first day of the 
              effective period on an intraday basis for the applicable 
              nomination cycle.  The nomination then will be processed as a 
              Timely Nomination for the remaining effective term of the 
              nomination.  Intraday nominations can be used to request 
              increases or decreases in total flow, changes to receipt points, 
              or changes to delivery points of scheduled gas.  Intraday 
              nominations may be used to nominate new supply or market.

              In the event capacity remains available after gas has been 
              scheduled or as a result of an operational or weather situation, 
              then Transporter may accept nominations or schedule service 
              after the time deadlines set forth above.  Any written 
              nominations received after the above stated deadlines will be 
              scheduled after nominations received before the nomination 
              deadline.

              Upon request by Transporter, Shipper shall from time to time 
              submit estimates of daily, monthly and annual quantities of gas 
              to be transported, including peak day requirements.

              (3) Bumping

                  Nominations submitted by a firm Shipper during the Evening 
                  or Intraday 1 Nomination Cycles shall be given scheduling 
                  priority over nominated and scheduled volumes for 
                  interruptible Shippers. Bumping is not permitted during the 
                  Intraday 2 Nomination Cycle.

                  When an interruptible Shipper's scheduled volumes are to be 
                  reduced as a result of a nomination submitted by a firm 
                  Shipper during the Evening or Intraday 1 Nomination Cycles, 
                  Transporter shall provide such interruptible Shipper advance 
                  notice that its scheduled volumes are to be reduced.  Such 
                  notification shall be as set forth in Section 9.3 herein.

                         GENERAL TERMS AND CONDITIONS
                                  (continued)

    9.2   Confirmation:  All nominations must be confirmed by Shipper in 
          writing via telecopy on the date of the nomination and must contain 
          a contact person for upstream and downstream confirmation. 
          Nominations shall not become effective until Transporter has 
          confirmed the nominated receipts and deliveries with the upstream 
          and downstream parties.  If such confirmation cannot be obtained, 
          transportation service will be delayed until such confirmation is 
          obtained.

          With respect to the Timely Nomination Cycle at a receipt or delivery 
          point, in the absence of agreement to the contrary, the lesser of 
          the confirmation quantities should be the confirmed quantity.  If 
          there is no response to a Request For Confirmation or an unsolicited 
          Confirmation Response, the lesser of the confirmation quantity or 
          the previously scheduled quantity should be the new confirmed 
          quantity.

          With respect to the processing of requests for increases during the 
          Evening, Intraday 1 or Intraday 2 Nomination Cycles, in the absence 
          of agreement to the contrary, the lesser of the confirmation 
          quantities should be the new confirmed quantity.  If there is no 
          response to a Request For Confirmation or an unsolicited 
          Confirmation Response, the previously scheduled quantity should be 
          the new confirmed quantity.

          With respect to the processing of requests for decreases during the 
          Evening, Intraday 1 or Intraday 2 Nomination Cycles, in the absence 
          of agreement to the contrary, the lesser of the confirmation 
          quantities should be the new confirmed quantity, but in any event no 
          less than the elapsed-prorated-scheduled quantity.  If there is no 
          response to a Request For Confirmation or an unsolicited 
          Confirmation Response, the greater of the confirmation quantity or 
          the elapsed-prorated-scheduled quantity should be the new confirmed 
          quantity.

          With respect to the preceding three paragraphs, if there is no 
          response to a request for confirmation or an unsolicited 
          confirmation response, the Transportation Service Provider should 
          provide the Service Requester with the following information to 
          explain why the nomination failed, as applicable:

          (1)   the Service Requester's Transportation Service Provider did 
                not conduct the confirmation;

          (2)   the Service Requester is told by its Transportation Service 
                Provider that the upstream confirming party did not conduct 
                the confirmation;

          (3)   the Service Requester is told by its Transportation Service 
                Provider that the upstream Service Requester did not have the 
                gas or submit the nomination;

          (4)   the Service Requester is told by its Transportation Service 
                Provider that the downstream confirming party did not conduct 
                the confirmation;

          (5)   the Service Requester is told by its Transportation Service 
                Provider that the downstream Service Requester did not have 
                the market or submit the nomination.

          This information should be imparted to the Service Requester on the 
          Scheduled Quantity document.

    9.3   Scheduling: Transporter shall schedule transportation quantities 
          based on Shippers' nominations, in accordance with the following
