                                   FOOTNOTES


1/    Section 154.107(f) of the Commission's Regulations requires a total 
      rate.  For this purpose only, a Daily Reservation Charge which equals 
      the Monthly Reservation Charge divided by 30.4167 (365 days/12 months) 
      is reflected.
   
      For capacity release transactions at maximum rate, the Monthly 
      Reservation Charge is divided by the number of Days in the applicable 
      Month.  For less than maximum rate transactions only, converting Daily 
      rate to Monthly rate is accomplished by multiplying the Daily rate times 
      number of Days in rate period, dividing the result by number of Months 
      in rate period and taking the remainder out to 5 decimal places and 
      rounding up or down to the fourth decimal place.  Converting a Monthly 
      rate to a Daily rate is accomplished by multiplying the Monthly rate by 
      the number of Months in rate period; dividing the result by number of 
      Days in rate period and taking the remainder out to 5 decimal places and 
      rounding up or down to the fourth decimal place.
   
2/    For the period during which this ACA Surcharge is effective, it is 
      Transporter's intent not to seek recovery of any annual charges assessed 
      pursuant to Part 382 of the Commission's Regulations and Commission 
      Order No. 472, except as permitted under this ACA Surcharge.  This ACA 
      Surcharge is in addition to any amounts otherwise payable to Transporter 
      under its Rate Schedules.
   
3/    Commencing on April 1, 2008, the MO Surcharge shall be assessed and 
      paid through a volumetric surcharge applicable to any Mainline 
      transportation service provided to a Shipper charged a discount or 
      negotiated rate pursuant to this FERC Gas Tariff under a Service 
      Agreement executed on or before December 31, 2007, but not to any 
      Shipper that receives transportation service through both the Mainline 
      Facilities and the Expansion Facilities under a Service Agreement 
      pursuant to Rate Schedule FT-2 executed on or before December 31, 2005. 
      In no event shall the sum of a discount rate and the MO Surcharge 
      exceed the otherwise applicable maximum tariff rate. The MO Surcharge 
      shall expire on April 1, 2013.

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

 4      The negotiated rate is a usage rate. Transporter shall have the right to terminate the 
        negotiated rate on one-day's notice if Shipper fails to transport at least 66% of its MDQ 
        on average during each calendar quarter. For any refund due and payable to Shipper for 
        any period pursuant to Transporter's FERC Gas Tariff, Shipper shall be deemed to have

 5      For any refund due and payable to Shipper for any period pursuant to Transporter's FERC 
        Gas Tariff, Shipper shall be deemed to have immediately assigned its right to the refund

 8      This is a usage rate equal to the applicable maximum daily reservation rates. No 
        reservation rate will apply. All other applicable rates and charges required or permitted 
        by the FERC are unaffected by this negotiated rate.

 9      Amendment to existing non-conforming service agreement, effective 11-01-07.

 10     Year to year evergreen until terminated by either party with 30 days' prior written 
        notice.

 11     The negotiated rate is a usage rate.

 12     In the event the Commission directs Transporter to redesign its rates prior to, or during 
        the effective period of this Negotiated Rate, or requires the collections of costs or 
        charges through the Negotiated Rate that are not now a component of such rate, the 
        parties agree to renegotiate the Negotiated Rate to take into account such actions. Such 
        renegotiated rate shall reflect the economic positions of the parties.

 13     The Negotiated Rates are:
               Rates       Period                   Receipt Point
               $0.10/Dt    04-01-08 to 10-31-08     Tennessee Old Lady Lake (Meter #23026)

      Transportation by Discovery Gas Transmission LLC (Transporter) of Gas 
      produced from Committed Production under the authority and provisions of 
      Part 284 of the Federal Energy Regulatory Commission's (Commission) 
      regulations, provided that:
   
      a.    Transporter determines that it has sufficient System Capacity to 
            render the Firm Transportation service and is able to provide said 
            Transportation;
   
      b.    Any construction, acquisition, or expansion of facilities 
            necessary to commence and provide the Firm Transportation service 
            has been completed;

      c.    Any Shipper requesting Firm Transportation service under Section 
            311 of the Natural Gas Policy Act (NGPA) has provided written 
            certification, including sufficient information to verify that the 
            requested service qualifies under Section 311 of the NGPA, and

      d.    Shipper satisfies the creditworthiness criteria of Section 10 of 
            the General Terms and Conditions;
   
      e.    Shipper executes the FT-2 Firm Service Agreement in the form 
            contained in this FERC Gas Tariff for service under this Rate 
            Schedule within ten (10) Business Days after it is provided to 
            Shipper; and
================================================================================


   
      f.    Shipper has committed the Committed Production to Transporter for 
            Transportation under this Rate Schedule and satisfactorily submits 
            documentation establishing P-50 reserves of the Committed 
            Production within eighteen (18) Months after committing the 
            Committed Production.  Shipper's MDVQ-Mainline and MDVQ-Expansion 
            established in accordance with Subsection 2.a. of this FT-2 Rate 
            Schedule for service, based on Shipper's good faith estimate 
            before the Committed Production is documented, will not be 
            increased as a result of such documentation unless firm capacity 
            is available at that time.

      g.    A Shipper with an Effective FT-2 Service Agreement may request an 
            increase of its MDVQ-Mainline or MDVQ-Expansion if the estimated 
            or proven amount of its Committed Production increases as the 
            result of documentation, or drilling additional wells or acquiring 
            additional Gas production rights in the blocks, lands and leases 
            dedicated to Transporter and described in Shipper's Effective FT-2

      a.    Transportation under this Rate Schedule is limited to Committed 
            Production as described in Shipper's Effective FT-2 Service 
            Agreement and is further limited to the MDVQ-Mainline or MDVQ-
            Expansion, as defined in this Subsection 2.a.
   
            Shipper's MDVQ-Mainline and MDVQ-Expansion for Transportation 
            service provided before Shipper satisfactorily documents the 
            Committed Production will be an amount equal to Shipper's good 
            faith estimate of the Committed Production divided by two thousand 
            nine hundred and twenty (2920).  This amount will be prorated, 
            based on the number of Days the FT-2 service is in effect prior to 
            the recalculation date, which will be January 1 of each Year.  
            Thereafter, the MDVQ-Mainline and MDVQ-Expansion will be 
            determined by subtracting the quantities of Gas shipped during the 
            previous Contract Year from the Committed Production
================================================================================



            and dividing the result by two thousand nine hundred and twenty 
            (2920).
   
      b.    Transportation service hereunder, through all or any portion of 
            the Mainline Facilities or Expansion Facilities, as appropriate, 
            on Transporter's System, will be Firm, subject to the availability 
            of capacity, to the provisions of an Effective FT-2 Firm Service 
            Agreement, and to the General Terms and Conditions.
   
      c.    Transportation service hereunder will consist of the acceptance by 
            Transporter of Gas tendered for the account of Shipper for 
            Transportation from the Primary Receipt Point(s) specified in an 
            Effective FT-2 Firm Service Agreement, the Transportation of that 
            Gas through the Mainline Facilities or Expansion Facilities, as 
            appropriate, on Transporter's System, and the delivery of that 
            Gas, after appropriate reductions for Fuel, Lost and Unaccounted 
            for Gas, for the account of Shipper at the Primary Delivery 
            Point(s) specified in an Effective FT-2 Firm Service Agreement or 
            Alternate Delivery Point(s) on the Mainline Facilities or 
            Expansion Facilities, as appropriate, as nominated by Shipper.
   
      d.    Transporter shall not be obligated to provide Transportation 
            service hereunder in excess of the MDVQ-Mainline and MDVQ-
            Expansion, as determined for each Contract Year in accordance with 
            Subsection 2.a.


      e.    Shipper shall submit documentation to Transporter in accordance 
            with Subsection 1.f. of this FT-2 Rate Schedule, proving the P-50 
            reserves of the Committed Production.  If, in Transporter's 
            reasonable judgment, the documentation submitted by Shipper fails 
            to establish the P-50 reserves of the Committed Production, 
            Transporter and Shipper will review the data underlying the 
            documentation and attempt to reach agreement.  If Transporter and 
            Shipper are unable to reach such agreement, Transporter and 
            Shipper will agree upon a qualified third-party expert whose good 
            faith determination shall establish the P-50 reserves of the 
            Committed Production and shall be binding upon Transporter and 
            Shipper.  Transporter and Shipper will share equally the costs of 
            the qualified third-party expert agreed to by Transporter and 
            Shipper.
   
      f.    If, after the commencement of production from Committed 
            Production, Shipper fails to ship at least fifty per cent (50%) of 
            its MDVQ-Mainline or MDVQ-Expansion during any consecutive twelve 
            (12) Month period, Transporter shall have the right to reduce 
            Shipper's MDVQ-Mainline or MDVQ-Expansion for the following 
            Contract Year.  
================================================================================


    The reduced MDVQ-Mainline or MDVQ-Expansion will be one hundred fifty per 
    cent (150%) of the Gas shipped through the Mainline Facilities or the 
    Expansion Facilities, respectively, during said twelve (12) Month period.  
    Shipper will have the opportunity to retain Firm service under Shipper's 
    FT-1 Rate Schedule equal to the reduction under Transporter's right of 
    first refusal procedures, as set forth in Section 12 of the General Terms 
    and Conditions.

      service under this Rate Schedule, a usage charge predicated upon a usage 
      rate that is less than the effective maximum usage rate set forth from 
      time to time on the currently effective Sheet No. 20 of this FERC Gas 
      Tariff; provided, that the usage rate may not be less than the effective 
      minimum usage rate.
   
      Transporter will file any and all reports as required by the 
      Commission's regulations setting forth the applicable discounted usage 
      rates and Shippers affected, along with any other required information.
   
   
4.    FUEL, LOST AND UNACCOUNTED FOR GAS
   
      In addition to the charges stated herein, each Shipper under this Rate 
      Schedule will be assessed its proportionate share of Fuel, Lost and 
      Unaccounted for Gas resulting from System operations.  Each Shipper's 
      deliveries from the System will be reduced by zero per cent (0.0%) from 
      its total receipts into the System until July 1, 2008.  Transporter will 
      calculate the actual amount of Fuel, Lost and Unaccounted for Gas 
      experienced during each calendar Year and file any revisions to the 
      reduction percentage to more closely approximate the actual amount of 
      Fuel, Lost and Unaccounted for Gas experienced by the System and to 
      reflect any differences between projections and actual fuel and losses 
      for the previous calendar Year.  The revised percentage of reduction 
      will be filed to become effective on July 1 of each Year.

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



2.     OPERATING PROVISIONS FOR FIRM SERVICE
   
   
2.1   AVAILABILITY OF FIRM SERVICE - Firm service under this FERC Gas Tariff 
      will be provided when, and to the extent that, Transporter determines 
      capacity is available in the Mainline Facilities or Expansion 
      Facilities, as appropriate, in its existing System that is not subject 
      to a superior claim by another Shipper and it is operationally feasible.  
      If operating conditions ever limit Transporter's ability to provide Firm 
      service, service will be provided on the basis described in Section 6 of 
      the General Terms and Conditions.
   
2.2   EXISTING, UNCOMMITTED CAPACITY - Existing, uncommitted Firm capacity 
      will be posted on Transporter's Internet web site (web site).  Requests 
      for posted capacity must be made by providing Transporter the specific 
      information in, and in the form prescribed by, Section 4 of the General 
      Terms and Conditions.  Each request must be accompanied by a Prepayment 
      of Ten Thousand Dollars ($10,000), and will be considered incomplete 
      unless the Prepayment is included.  Transporter will evaluate all 
      complete requests in the order received and will notify Shipper in 
      writing of the acceptance of a complete request.  Transporter shall not 
      be required to accept a request for Firm service at a rate that is less 
      than its currently effective maximum rate.  Request for Service forms 
      will be supplied to any potential Shipper upon request, and are 
      available at Transporter's offices during normal business hours, or 
      electronically on the web site by following the procedures of Section 17 
      of the General Terms and Conditions.
================================================================================



2.3   NEW CAPACITY - In the event new capacity becomes available due to the 
      construction or acquisition of facilities or the expansion of existing 
      facilities, pursuant to authorization under Section 7 of the Natural Gas 
      Act and the Commission's regulations, Transporter shall hold an open 
      season with a minimum duration of ten (10) calendar Days during which 
      potential Shippers may submit requests for Firm service in accordance 
      with the provisions of the open season notice.  Each request for Firm 
      service must be made by submitting a completed Request for Service form 
      and a Prepayment in the amount of Ten Thousand Dollars ($10,000).  
      Request for Service forms will be supplied to any potential Shipper upon 
      request, and are available at Transporter's offices during normal 
      business hours, or electronically on the Internet web site (web site) by 
      following the procedures of Section 17 of the General Terms and 
      Conditions.
   
      If at the end of the open season there is insufficient capacity to fill 
      all valid requests, then each valid request will be assigned a value 
      determined by multiplying the rate, not to exceed the maximum rate, the 
      term, and the quantity requested.  Requests for a term of more than one 
      (1) Month that vary in rate or term will be assigned a total present 
      value based on the Commission's current Interest Rate.  If requests for 
      service providing the same value exceed the Available Capacity, then the 
      Available Capacity will be prorated among those requests.  Shippers that 
      stipulated in their requests that they would not accept less than the 
      amount requested will not be included in the pro rata allocation.  
      Transporter shall not be required to consider requests for service or 
      award capacity if the rate stipulated in a request for service is less 
      than Transporter's maximum rate.
================================================================================



2.4   PRIORITY OF SERVICE - The Firm Transportation of Gas at Receipt and 
      Delivery Points will have the following priority for service under an 
      Effective Firm Service Agreement:
   
      a.    Receipt Point Priority - The receipt of Gas from Primary and 
            Alternate Receipt Points will be on a Firm basis except as 
            provided in Sections 6 and 21 of the General Terms and Conditions.  
            The receipt of Gas from Alternate Receipt Points will be 
            subordinate to the receipt of Gas from Primary Receipt Points and 
            superior to the receipt of Gas for Interruptible Transportation 
            service.

      b.    Delivery Point Priority - The delivery of Gas to Primary and 
            Alternate Delivery Points will be on a Firm basis except as 
            provided in Sections 6 and 21 of the General Terms and Conditions.  
            The delivery of Gas to Alternate Delivery Points will be 
            subordinate to the delivery of Gas to Primary Delivery Points and 
            superior to the delivery of Gas for Interruptible Transportation 
            service.

2.5   RECEIPT AND DELIVERY POINT DESIGNATIONS - Each Receipt Point and each 
      Delivery Point specified in an Effective Firm Service Agreement will be 
      designated Primary Receipt Points and Primary Delivery Points for Firm 
      Transportation service.  Each Shipper's MDRQ-Mainline and MDRQ-Expansion 
      or MDVQ-Mainline and MDVQ-Expansion must be allocated among the Primary 
      Receipt Points and Primary Delivery Points such that the MDRQ-Mainline 
      and MDRQ-Expansion or the MDVQ-Mainline and MDVQ-Expansion equals both 
      the sum of the MDQs for Primary Receipt Points and the sum of the MDQs 
      for Primary Delivery Points.  A Shipper may amend its FT-1 Service 
      Agreement to add, delete, or modify Primary Receipt or Delivery Point 
      MDQs, or its FT-2 Service Agreement to add, delete, or modify Primary 
      Delivery Point MDQs, provided Firm capacity is available.  In such 
      event, the MDQs must be reallocated as necessary so that the sum of the 
      MDQs for Primary Receipt Points and the sum of the MDQs for Primary 
      Delivery Points in the amended Firm Service Agreement do not exceed the 
      MDRQ-Mainline and MDRQ-Expansion or the MDVQ-Mainline and MDVQ-
      Expansion.  Transporter reserves the right to limit the number of such 
      amendments per Service Agreement to five (5) per Month in order to avoid 
      administrative burdens.
================================================================================



2.6   MODIFICATION OF PRIMARY RECEIPT POINTS - A Shipper with an Effective FT-
      1 Service Agreement may change its Primary Receipt Point on a temporary 
      basis by designating any downstream Receipt Point within its Primary 
      Path as its Primary Receipt Point for up to ninety (90) Days without 
      losing its right to return to its permanent Primary Receipt Point.  Use 
      of such point is subject to availability and all other terms of 
      Shipper's Effective FT-1 Service Agreement, the FT-1 Rate Schedule, and 
      Transporter's General Terms and Conditions.  The availability of 
      capacity at Shipper's permanent Primary Receipt Point will be subject to 
      such right.  Any other Shipper that wishes to use that point will be 
      informed that another Shipper has the right to return to the Receipt 
      Point.
   
2.7   ALTERNATE POINTS - All System points on the Mainline Facilities or 
      Expansion Facilities, as appropriate, where capacity exists in excess of 
      capacity allocated to provide Primary Receipt Point or Primary Delivery 
      Point Firm Transportation service will be available to FT-1 Shippers as 
      Alternate Receipt or Delivery Points.  All System points on the Mainline 
      Facilities or Expansion Facilities, as appropriate, where capacity 
      exists in excess of capacity allocated to provide Primary Delivery Point 
      Firm Transportation service will be available to FT-2 Shippers as 
      Alternate Delivery Points.  Alternate Delivery Point(s), at which 
      Transporter may deliver Gas for the account of Shipper, shall include 
      all Delivery Points located on the Mainline Facilities or the Expansion 
      Facilities, as the case may be, subject to the availability of firm 
      capacity to such Delivery Points and Shipper's MDVQ-Mainline or MDVQ-
      Expansion, respectively.
   
      Any discounted reservation rate for Firm Transportation service between 
      Primary Receipt and Delivery Points will not automatically transfer to 
      service using Alternate Receipt or Delivery Points, unless Transporter 
      directs Shipper to use an Alternate point for operational reasons 
      pursuant to Subsection 7.2 of the General Terms and Conditions.
================================================================================



2.8   REQUEST INVALIDATION - Requests for service submitted by potential 
      Shippers after the initial in-service date of Transporter's System will 
      be deemed invalid if service is requested to commence more than ninety 
      (90) Days after a request for service is submitted, unless new or 
      additional facilities are required to provide the service.  If new or 
      additional facilities are required to provide the service, requests for 
      service using said facilities may not specify a service commencement 
      date more than thirty (30) Days after the in-service date of the new 
      facilities.
   
2.9   REQUESTS FOR OPERATING DATA - Upon request by Transporter, Shipper shall 
      submit estimates of daily, monthly and annual quantities of Gas to be 
      transported, including peak day requirements, together with the 
      estimated amounts thereof applicable to each Primary Receipt Point and 
      Primary Delivery Point.  Transporter will use such information and 
      operating data to determine its System's Available Capacity, to evaluate 
      potential System Capacity needs, to plan its maintenance and repair 
      operations, and to assure adequate service to its Shippers.
   
2.10  ADDITIONAL FACILITIES - Transporter shall not be required to construct 
      additional facilities, modify or expand facilities, or acquire 
      facilities to provide Firm Transportation service.

2.11  FUTURE EMERGENCY SERVICE - If, within five years from the date of a Rate 
      Schedule FT-2 Service Agreement between Transporter and a Shipper (the 
      "Funding Shipper") that reimburses Transporter for the costs of the 
      facilities installed during 2005 following Hurricane Katrina to create 
      additional capacity by reversing flow on the Expansion Facilities to 
      receive gas from the delivery point at Tennessee Gas Pipeline Company, 
      Transporter decides (in its sole discretion) to use the same facilities 
      during a future emergency, the Funding Shipper shall have a higher 
      priority in the allocation of such capacity but only to the extent that 
      all other aspects of the Funding Shipper's bid for the capacity are 
      equal to the competing bids as measured pursuant to Transporter's FERC 
      Gas Tariff.
================================================================================



3.    OPERATING PROVISIONS FOR INTERRUPTIBLE SERVICE
   
   
3.1   AVAILABILITY OF INTERRUPTIBLE SERVICE - Interruptible service under this 
      FERC Gas Tariff will be provided when, and to the extent that, 
      Transporter determines capacity is available in its existing System that 
      is not subject to a superior claim by another Shipper or another class 
      of service.  Available Interruptible capacity will be allocated by 
      Transporter in accordance with Subsection 3.2.
   
3.2   PRIORITY OF SERVICE - Interruptible Transportation services will be 
      subordinate to Firm Transportation services provided by Transporter.  
      Transporter will allocate available Interruptible capacity on a daily

      basis of rate.  Capacity at each rate level will be allocated on a pro 
      rata basis.
   
3.3   SHIPPER REQUESTS FOR INTERRUPTIBLE SERVICE - Requests for Interruptible 
      service hereunder must be made by providing the specific information in, 
      and in the form prescribed by, Section 4 of the General Terms and 
      Conditions.  Request for Service forms will be supplied to any potential 
      Shipper upon request, and are available at Transporter's offices during 
      normal business hours or electronically on Transporter's Internet web 
      site (web site) by following the procedures in Section 17 of the General 
      Terms and Conditions.
   
3.4   REQUESTS FOR OPERATING DATA - Upon request of Transporter, Shipper shall 
      submit estimates of daily, monthly and annual quantities of Gas to be 
      transported, including peak day requirements, together with the 
      estimated amounts thereof applicable to each Receipt Point and Delivery 
      Point.  Transporter will use such information and operating data to 
      determine its System's Available Capacity, to evaluate potential System 
      Capacity needs, to plan its maintenance and repair operations, and to 
      assure adequate service to its Shippers.
================================================================================



3.5   RECEIPT AND DELIVERY POINTS - Each Receipt Point and each Delivery Point 
      on Transporter's System is available for Interruptible Transportation 
      service, subject to the prior allocation of capacity at such points to 
      Firm Transportation services, up to the MDTQ-Mainline and MDTQ-Expansion 
      set forth in a Shipper's Effective IT Service Agreement with 
      Transporter.
   
3.6   INTERRUPTION OF SERVICE - Transporter retains all rights at any and all 
      times during the term of an Effective IT Service Agreement to decrease 
      or temporarily suspend receipt and/or delivery of Gas if the capacity is 
      required for a higher priority service or Shipper.  If Transporter 
      exercises such right, Shipper shall hold Transporter harmless from any 
      loss, claim, damage or expense that such Shipper or other party may 
      incur by reason of such decrease or suspension.
   
3.7   FAILURE TO USE SERVICE - If Shipper fails to nominate service within 
      twelve (12) Months after the execution of an IT Service Agreement or 
      during any consecutive twelve (12) Month period, Transporter may 
      terminate the IT Service Agreement on thirty (30) Days  prior written 
      notice.

4.2   INCOMPLETE SERVICE FORMS - Request for Service forms received by 
      Transporter that do not include the Prepayment required by Subsection 
      4.1., or do not contain all the requested information, including credit 
      information sufficient to demonstrate that a Shipper will be able to 
      meet its financial obligations under the requested Service Agreement, 
      will be considered incomplete.  Transporter will notify Shipper of any 
      deficiencies and Shipper's request for service will not be considered 
      until all of the required information is provided to Transporter.  The 
      request for service will be deemed invalid if Shipper fails to provide 
      the required information within ten (10) Business Days after 
      notification by Transporter that the request is incomplete.
================================================================================



5.    NOMINATION PROCEDURES
   
   
5.1   REQUIRED INFORMATION - For each Day on which Shipper desires 
      Transportation service under any Service Agreement, Shipper shall submit 
      to Transporter the daily quantity of Gas, expressed in Dts, that it has 
      available for Transportation at each Receipt Point and the quantity of 
      Gas Shipper desires to have delivered at each Delivery Point.  Shipper's 
      Receipt Point nominations, minus Lost and Unaccounted for Gas, must 
      equal its Delivery Point nominations on each Day.  Shipper may submit 
      either a written or an electronic nomination in the format set forth in 
      the NAESB Standards.  Once submitted, nominations, except for Intraday 
      Nominations, will remain in effect for the specified period of time 
      unless a prospective written or electronic nomination change is received 
      from Shipper.  Each Shipper nomination must include the information 
      required by the NAESB Standards.
   
      When a nomination for a date range is received, each Day within that 
      range is considered an original nomination. When a subsequent nomination 
      is received for one or more Days within that range, the previous 
      nomination is superseded by the subsequent nomination only to the extent 
      of the Days specified.  The Days of the previous nomination outside the 
      range of the subsequent nomination are unaffected.  Nominations have a 
      prospective effect only.
================================================================================



5.2   NOMINATION DEADLINES -
   
      a.    The Timely Nomination Cycle - The standard nominations timeline is 
            as follows:  11:30 a.m. for nominations leaving control of the 
            nominating party;  11:45 a.m. for receipt of nominations by 
            Transporter (including from Title Transfer Tracking Service 
            Providers (TTTSPs));  noon to send Quick Response;  3:30 p.m. for 
            receipt of completed confirmations by Transporter from upstream 
            and downstream connected parties; 4:30 p.m. for receipt of 
            scheduled quantities by Shipper and point Operator (Central Clock 
            Time on the Day prior to flow).
   
       b.   Intraday Nominations - A Shipper may submit and Transporter will 
            accept Intraday nominations, provided:  (i) such nominations are 
            within  Shipper's total MDRQ-Mainline, MDRQ-Expansion, MDVQ-
            Mainline and MDVQ-Expansion or MDTQ-Mainline and MDTQ-Expansion 
            and (ii) such nominations can be confirmed.  Intraday Nominations 
            may be used to start service, to request increases or decreases in 
            nominated quantities, to nominate new supply or market, or to 
            reflect changes in the specified Receipt and Delivery Points.
   
            Intraday Nominations will be effective only for a single Gas Day, 
            and, therefore, will not remain in effect for prospective Days.  
            To the extent a Shipper submits an Intraday Nomination (including 
            nominations received after the standard nomination deadline) which 
            specifies an effective term of longer than one Gas Day, 
            Transporter will make the nomination effective only for the first 
            Gas Day of the specified effective period.
   
            Intraday Nominations may be submitted to Transporter at any time, 
            and will be scheduled in accordance with Section 6.3 of this FERC 
            Gas Tariff. Except as provided in iii. below, Intraday Nominations 
            for firm transportation services will be given priority over 
            scheduled and flowing interruptible transportation services.
================================================================================



            Intraday Nominations will be scheduled in one of three "Cycles" 
            and will be processed according to the following timelines:

                  TTTSPs);  6:30 p.m. to send Quick Response;  9:00 p.m. for 
                  receipt of completed confirmations by Transporter from 
                  upstream and downstream connected parties;  10:00 p.m. for 
                  Transporter to provide scheduled quantities to affected 
                  Shippers and point Operators, and to provide scheduled 
                  quantities to bumped parties (notice to bumped parties), 
                  (Central Clock Time on the Day prior to flow).
   
                  Scheduled quantities resulting from an Evening Nomination 
                  that does not cause another Shipper to receive notice that 
                  it is being bumped should be effective at 9:00 a.m. on the 
                  Gas Day; and when an Evening Nomination causes another 
                  Shipper to receive notice that it is being bumped, the 
                  scheduled quantities should be effective at 9:00 a.m. on the 
                  Gas Day.

            ii.   The Intraday 1 Nomination Cycle: 10:00 a.m. for nominations 
                  leaving control of the nominating party; 10:15 a.m. for 
                  receipt of nominations by Transporter (including from 
                  TTTSPs); 10:30 a.m. to send Quick Response; 1:00 p.m. for 
                  receipt of completed confirmations by Transporter from 
                  upstream and downstream connected parties; 2:00 p.m. for 
                  Transporter to provide scheduled quantities to affected 
                  Shippers and point Operators, and to provide scheduled 
                  quantities to bumped parties (notice to bumped parties), 
                  (Central Clock Time on Gas Day).  Scheduled quantities 
                  resulting from Intraday 1 Nominations should be effective at 
                  5:00 p.m. on the Gas Day.
================================================================================


      iii.  The Intraday 2 Nomination Cycle: 5:00 p.m. for nominations leaving

            send Quick Response; 8:00 p.m. for receipt of completed 
            confirmations by Transporter from upstream and downstream 
            connected parties; 9:00 p.m. for Transporter to provide scheduled 
            quantities to affected Shippers and point Operators (Central Clock 
            Time on the Gas Day).
   
            Scheduled quantities resulting from Intraday 2 Nominations should 
            be effective at 9:00 p.m. on the Gas Day.  Bumping is not allowed 
            during the Intraday 2 Nomination Cycle.

      iv.   For purposes of Section 5.2 b(i), b(ii), and b(iii) of the FERC 
            Gas Tariff, "provide" shall mean, for transmittals pursuant to 
            standards 1.4.x (NAESB standards relating to nomination datasets), 
            receipt at the designated site, and for purposes of other forms of 
            transmittal, it shall mean send or post.
   
      c.    Quick Response - Transporter will send a Quick Response, as 
            defined by NAESB, to Shipper for each nomination received.  Such 
            Quick Response will serve only as notification of the receipt and 
            validation of nomination information in accordance with NAESB 
            Standards, but will not indicate whether the nomination will be 
            confirmed or scheduled pursuant to Subsections 6.2 and 6.3 of this 
            FERC Gas Tariff.
   
            For standard nominations, the Quick Response will be sent to the 
            nominating party by 12:00 p.m. Central Clock Time on the Day the 
            nomination is received.  For Intraday Nominations, the Quick 
            Response will be sent according to the following schedule: Batch 1 
            Nomination Cycle - 6:30 p.m. Central Clock Time on the Day prior 
            to flow; Batch 2 Nomination Cycle - 10:30 a.m. Central Clock Time 
            on the Gas Day; Batch 3 Nomination Cycle - 5:30 p.m. Central Clock 
            Time on the Gas Day.

      d.    Notification to Bumped Shippers - Transporter will notify 
            individual Shippers of bumped quantities by telephone or facsimile 
            in accordance with the timelines for Batch 1 and Batch 2 
            Nomination Cycles.
   
      e.    Waiver of Penalties - To the extent that a Shipper is bumped as a 
            result of an Intraday nomination by a Shipper with a higher 
            priority of service, Transporter will waive any applicable 
            penalties incurred by Shipper solely as a result of the Intraday 
            bump, and only for the Day on which Shipper is bumped.
================================================================================



5.3   REQUIRED NOMINATION CHANGES - Transporter may require revised 
      nominations or prospective nomination changes by Shipper if the daily 
      flows under a particular Service Agreement differ from confirmed 
      nominations, or if an imbalance has occurred due to operational reasons.  
      When a Shipper receives notice requiring a revised nomination or 
      prospective nomination change, Shipper shall submit a nomination in 
      accordance with Subsection 5.1 and with the revisions specified by 
      Transporter.  Shipper shall be responsible for informing its upstream 
      and downstream parties of the changes.
   
5.4   DELEGATION OF NOMINATION AUTHORITY TO AGENT - A Shipper may delegate to 
      any third party the responsibility for submitting nominations and 
      receiving confirmations or performing other administrative duties under 
      any Effective Agreement, subject to the following conditions:

      a.    Any designation of a third party as agent, or any change in such 
            designation, must be provided in writing to Transporter at least 
            two (2) Business Days prior to the requested effective date of the 
            designation.
   
      b.    The written designation must specify any limits on the authority 
            of the Agent, including any time limit for the designation.  
            Transporter may reject any Shipper's request to delegate 
            responsibilities if the limitations on the designation would 
            impose undue administrative burdens on Transporter.
   
      c.    Transporter will rely on communications from a Shipper's agent for 
            all nomination purposes except to the extent the designation is 
            expressly limited.  Communications by Transporter to such Agent 
            will be deemed notice to Shipper.
================================================================================



      d.    Any third party may administer multiple Service Agreements as the 
            agent for one or more Shippers, but the agent must make 
            nominations and otherwise administer and account separately for 
            each Service Agreement.
   
5.5   SHIPPER PRIORITIZATION OF NOMINATED QUANTITIES - If Shipper elects to 
      nominate quantities of Gas to be received by Transporter from one or 
      more upstream parties at one or more Receipt Points for delivery by 
      Transporter to one or more downstream parties at one or more Delivery 
      Points for the account of Shipper, Shipper shall provide the priority, 
      method, and extent to which each nominated receipt quantity from a 
      particular upstream party at a particular Receipt Point should be 
      reduced in the event that any downstream Operator verifies and confirms 
      deliveries that are less than the Shipper's nominated deliveries, or in 
      the event that, due to Transporter's allocation of Available Capacity 
      for Transportation services, all nominated receipts cannot be scheduled.  
      Likewise, if Shipper elects to nominate quantities of Gas to be 
      delivered by Transporter to one or more downstream parties at one or 
      more Delivery Points for the account of Shipper, Shipper shall provide 
      the priority, method, and extent to which each nominated delivery 
      quantity to a particular downstream party at a particular Delivery Point 
      should be reduced in the event that any upstream Operator verifies and 
      confirms receipts that are less than the Shipper's nominated receipts, 
      or in the event that, due to Transporter's allocation of Available 
      Capacity for Transportation services, all nominated deliveries cannot be 
      scheduled.
   
      Shipper prioritization of nominated quantities must be consistent with 
      the terms of this FERC Gas Tariff and such prioritization will be 
      honored to the extent that Transporter reasonably determines such 
      prioritization is operationally feasible and the conditions of 
      Subsection 8.4 have been met.
================================================================================



6.    SCHEDULING AND CURTAILMENT
   
6.1   ALLOCATION OF AVAILABLE CAPACITY - Each Day, upon consideration of 
      prevailing operating conditions, scheduled or unscheduled maintenance or 
      repairs, and similar conditions, Transporter will allocate Available 
      Capacity in sequence on the basis of Receipt Point priorities, followed 
      by mainline segment capacity priorities, and finally by Delivery Point 
      priorities, in the following manner:
   
       a.   Receipt Point capacity will be allocated to Firm Shippers who have 
            designated the nominated Receipt Point on the Mainline Facilities 
            or the Expansion Facilities, as appropriate, as a Primary Receipt 
            Point in an Effective FT-1 or FT-2 Service Agreement, followed by 
            allocation to Shippers who have nominated the Receipt Point on the 
            Mainline Facilities or the Expansion Facilities, as appropriate, 
            as an Alternate Receipt Point under an Effective FT-1 Service 
            Agreement.  Any remaining Receipt Point capacity on the Mainline 
            Facilities or the Expansion Facilities, as appropriate, will be 
            allocated to Interruptible Shippers on the basis of rate, with the 
            Shipper paying the highest rate, up to the maximum rate, scheduled 
            first.  Shippers having the same level of priority as stated 
            herein will be scheduled on a pro rata basis.  In the case of a 
            Negotiated Rate for Interruptible Service that exceeds the 
            maximum, Commission-approved tariff rate, the Negotiated Rate will 
            be deemed to equal the maximum rate for the purposes of this 
            section.  A Negotiated Rate that is less than the maximum rate 
            will be considered in the same manner as recourse rates.
================================================================================



      b.    Capacity on the Mainline Facilities and the Expansion Facilities, 
            respectively, will be allocated in the following sequence, from 
            highest priority to lowest priority: Primary Firm Receipt Points 
            to Primary Firm Delivery Points, Primary Firm Receipt Points to 
            Alternate Firm Delivery Points, Alternate Firm Receipt Points to 
            Primary Firm Delivery Points, Alternate Firm Receipt Points to 
            Alternate Firm Delivery Points, and Interruptible Receipt Points 
            to Interruptible Delivery Points.
   
      c.    Delivery Point capacity will be allocated first to Firm Shippers 
            who have designated the nominated Delivery Point on the Mainline 
            Facilities or the Expansion Facilities, as appropriate, as a 
            Primary Delivery Point in an Effective FT-1 or FT-2 Service 
            Agreement, followed by allocation to Shippers who have nominated 
            the Delivery Point on the Mainline Facilities or the Expansion 
            Facilities, as appropriate, as an Alternate Delivery Point.
   
            Any remaining Delivery Point capacity on the Mainline Facilities 
            or the Expansion Facilities will be allocated to Interruptible 
            Shippers on the basis of rate, with the Interruptible Shipper 
            paying the highest rate, up to the maximum rate, scheduled first.  
            Shippers having the same level of priority as stated herein will 
            be scheduled on a pro rata basis.  In the case of a Negotiated 
            Rate for Interruptible Service that exceeds the maximum, 
            Commission-approved tariff rate, the Negotiated Rate will be 
            deemed to equal the maximum rate for the purposes of this section.  
            A Negotiated Rate that is less than the maximum rate will be 
            considered in the same manner as recourse rates.
================================================================================



6.2   CONFIRMATION OF NOMINATED QUANTITIES - Nominations made in accordance 
      with Section 5 of the General Terms and Conditions will not be effective 
      until Transporter has confirmed the nominated receipts with upstream 
      Operators and the nominated deliveries with downstream Operators.  
      Shipper must advise Transporter of the appropriate contact persons for 
      upstream and downstream Operators who have the authority to verify and 
      confirm nominated Gas quantities.  Prior to scheduling nominated 
      quantities for Transportation service requested by Shippers, Transporter 
      will contact the appropriate Operators at the designated Receipt and 
      Delivery Points in order to confirm the nominated quantities.  
      Transporter may reject, in whole or in part, any nominated quantities 
      where the daily quantities of Gas Shipper desires to be transported, the 
      upstream shipper name(s) and contract number(s), or the downstream 
      shipper name(s) and contract number(s) fail to conform to the 
      information provided by the designated Operators at the Receipt and 
      Delivery Points.  If all information conforms except for the daily 
      quantities of Gas Shipper desires to have Transporter receive or 
      deliver, Transporter will schedule and confirm the nomination at the 
      lower of the daily quantities nominated by Shipper and the daily 
      quantities the Operators can confirm for scheduling at the designated 
      Receipt and Delivery Points.  Transporter will provide notification of 
      Shipper's confirmed Transportation quantities either by telephone, 
      facsimile, or electronically.  Shipper shall be responsible for 
      informing its upstream and downstream parties of any differences between 
      confirmed quantities and nominated quantities.
   
      For Standard Nominations, Transporter will receive completed 
      confirmation from upstream and downstream operators by 3:30 p.m. Central 
      Clock Time on the Day prior to flow.

      For Intraday Nominations, Transporter will receive completed 
      confirmations from upstream and downstream operators according to the 
      following schedule:  Batch 1 Nomination Cycle - 9:00 p.m. Central Clock 
      Time on the Day prior to flow; Batch 2 Nomination Cycle - 1:00 p.m. 
      Central Clock Time on the Gas Day; Batch 3 Nomination Cycle - 8:00 p.m. 
      Central Clock Time on the Gas Day.
================================================================================



6.3   SCHEDULING NOMINATED QUANTITIES - Promptly upon the close of the 
      nomination deadline for each nomination cycle, Transporter will evaluate 
      all timely nominations and the Available Capacity of its System.  
      Transporter will schedule nominated quantities of Gas to the extent 
      capacity is available in accordance with Subsection 6.1 and to the 
      extent nominations can be confirmed in accordance with Subsection 6.2.  
      Transporter shall not be required to schedule quantities of Gas at any 
      Receipt or Delivery Point where the cumulative daily nominated 
      quantities at such Receipt or Delivery Point are below the quantities 
      required to meet the measurement standards as prescribed in API Manual 
      of Petroleum Measurement Standards, Chapter 14, Section 3, Latest 
      Edition. Transporter will first schedule nominated quantities under Firm 
      Service Agreements followed by nominated quantities under Interruptible 
      Service Agreements, in the following manner:
   
      a.    Firm Transportation service from Primary Receipt Points to Primary 
            Delivery Points;
   
      b.    Firm Transportation service from Primary Receipt Points to 
            Alternate Delivery Points;
   
      c.    Firm Transportation service from Alternate Receipt Points 
            downstream of the Primary Receipt Points to Primary Delivery 
            Points;
   
      d.    Firm Transportation service from Alternate Receipt Points upstream 
            of the Primary Receipt Points to Primary Delivery Points;

      e.    Firm Transportation service from Alternate Receipt Points 
            downstream of the Primary Receipt Points to Alternate Delivery 
            Points;

      f.    Firm Transportation service from Alternate Receipt Points upstream 
            of the Primary Receipt Points to Alternate Delivery Points;

      g.    IT Transportation service from Receipt Points to Delivery Points 
            on the basis of rate paid.
================================================================================



      Following scheduling of confirmed standard nominations, Transporter will 
      furnish a report to the Shipper and point operator for receipt by 4:30 
      p.m. Central Clock Time the Day before the effective date of the 
      requested service showing the scheduled receipt and delivery quantities 
      by contract number, Receipt Point and Delivery Point.  Following 
      scheduling of confirmed Intraday Nominations, Transporter will furnish a 
      report to the Shipper and point operator showing the scheduled receipt 
      and delivery quantities by contract number and receipt/delivery point 
      according to the following schedule:  Batch 1 Nomination Cycle - 10:00 
      p.m. Central Clock Time on the Day prior to flow; Batch 2 Nomination 
      Cycle - 2:00 p.m. Central Clock Time on the Gas Day; Batch 3 Nomination 
      Cycle - 9:00 p.m. Central Clock Time on the Gas Day.  At the end of each 
      Gas Day, Transporter will provide the final scheduled quantities for the 
      just completed Gas Day.  For written nominations, such communication may 
      be made by facsimile or other acceptable means of electronic 
      correspondence.  For electronic nominations, Transporter will send a 
      report in accordance with the NAESB standards.
================================================================================



6.4   CHANGES IN DAILY SCHEDULED QUANTITIES - After Shipper has submitted a 
      standard nomination and Transporter has confirmed and scheduled the 
      quantities of Gas to be transported, such quantities will remain 
      scheduled until the ending date specified in the nomination unless:
   
      a.    A prospective nomination is received from Shipper requesting a 
            change in previously confirmed and scheduled quantities; or
   
      b.    A prospective nomination is required by Transporter in accordance 
            with Subsection 5.3 of the General Terms and Conditions; or
   
      c.    Transportation service is curtailed or interrupted in order to 
            provide service for a higher priority service or Shipper; or
   
      d.    The designated contact persons with upstream and downstream 
            Operators who have the authority to verify and confirm nominated 
            Gas quantities or require a reduction of the confirmed and 
            scheduled quantities; or
   
      e.    Receipts or deliveries at a particular Receipt Point or Delivery 
            Point are outside the established tolerance levels specified in an 
            Effective OBA; or

      f.    Adjustments of receipts or deliveries at a particular Receipt 
            Point or Delivery Point are required as specified in an OFO; or
   
      g.    Capacity used in providing service is inadequate as a result of a 
            force majeure event, overbooking of capacity, or an operational 
            limiting event.
   
      h.    Other reasons required or permitted under this FERC Gas Tariff.
================================================================================



6.5   CURTAILMENT - If, at any time, Transporter determines, that because of 
      operating or other conditions affecting its System the capacity of all 
      or part of its System on the Mainline Facilities or Expansion 
      Facilities, as appropriate, is insufficient to serve all Transportation 
      quantities confirmed and scheduled on a Day, Transportation services 
      will be curtailed on all or part of the System on the Mainline 
      Facilities or Expansion Facilities, as appropriate, where capacity is 
      insufficient as follows:
   
      a.    IT Transportation service to Delivery Points from Receipt Points 
            on the basis of rate paid, with the lowest rate curtailed first.
   
      b.    Firm Transportation service.
   
      In the case of a Negotiated Rate for Interruptible Service that exceeds 
      the maximum, Commission-approved tariff rate, the Negotiated Rate will 
      be deemed to equal the maximum rate for the purposes of this section.  A 
      Negotiated Rate that is less than the maximum rate will be considered in 
      the same manner as recourse rates.
   
      Pro rata curtailments of Gas quantities will be based on the ratio of 
      each Shipper's confirmed and scheduled Transportation quantities to the 
      total confirmed and scheduled quantities by all Shippers at the same 
      priority multiplied by the amount of Available Capacity.
   
      If capacity is limited on only part of Transporter's System, including 
      any Delivery and/or Receipt Point(s), Transporter's curtailment orders 
      pursuant to Subsection 6.8 will be limited to the Transportation 
      services confirmed and scheduled for such part(s) of Transporter's 
      System.
================================================================================



6.6   NOTICE OF CURTAILMENT - Transporter will post notices of curtailment on 
      its web site, and, if necessary, notify all affected shippers as soon as 
      practicable, and in a manner that is reasonable under existing 
      conditions, that a period of curtailment exists.  Such notice will set 
      forth any limits on receipts or deliveries and the anticipated duration 
      of such curtailment period.  Upon notice of curtailment, Shipper shall 
      adjust its receipts and/or deliveries of Gas as specified by Transporter 
      within the time period specified by Transporter.  Shipper compliance 
      will be a change in Gas flow to the level specified by Transporter and 
      will be evidenced by the confirmation of a flow rate change by an 
      upstream or downstream Operator or the confirmation of the flow rate 
      change by Transporter.
   
6.7   CURTAILMENT PENALTIES - Failure of any Shipper to adjust its receipts 
      and/or deliveries within the time and in the manner specified by 
      Transporter will result in the imposition of curtailment penalties.  All 
      Gas received or delivered for the account of Shipper after notification 
      of a curtailment under Subsection 6.6 that deviates from the quantities 
      set by Transporter in the notice of curtailment will be assessed a 
      penalty of Twenty-Five Dollars ($25.00) per Dt.  The imposition of a 
      curtailment penalty will not relieve Shipper of its obligations to 
      resolve any imbalance created during a period of curtailment.  Although 
      a notice of curtailment must result in an immediate change in Gas flow, 
      Transporter will not assess penalties unless notice of curtailment is 
      given at least twelve (12) hours before the curtailment is required.  
      Net penalty revenues will be applied to Transporter's Fuel, Lost and 
      Unaccounted for Gas account.
   
6.8   EMERGENCY PROCEDURES - Variations in the curtailment procedures set 
      forth in Subsection 6.5 may be permitted by Transporter when necessary 
      to respond to emergency situations (including environmental emergencies) 
      where supplemental deliveries are required to forestall injury to life 
      or property.
================================================================================





7.    OPERATIONAL FLOW ORDER (OFO)
   
7.1   APPLICABILITY - An Operational Flow Order (OFO) is an order issued to 
      alleviate conditions, inter alia, which threaten or could threaten the 
      safe operations or system integrity of Transporter's system or to 
      maintain operations required to provide efficient and reliable firm 
      service.  Whenever Transporter experiences these conditions, any 
      pertinent order will be referred to as an Operational Flow Order.  
      Transporter will determine, in its reasonable judgment, the 
      circumstances that will result in the issuance of an OFO.
   
      Circumstances that may prompt an OFO cannot be quantified in advance 
      because the need to issue an OFO will depend on quantities of Gas 
      confirmed and scheduled, the point(s) where actual receipts or 
      deliveries deviate from confirmed and scheduled quantities, whether an 
      OBA governs the allocation at the point(s), and the relationship of 
      these individual factors to general System operations on any given Day.  
      Generally, an OFO may be issued if there is a significant decrease or 
      increase in line pressure or if a curtailment order fails to reduce gas 
      flow in the event there is insufficient capacity to handle all confirmed 
      and scheduled nominations.
   
      OFOs will identify the situation to be addressed and will identify 
      specific actions to be taken by Shipper, stated in terms of an hourly 
      Gas flow level, and the probable duration of an OFO.  Transporter will 
      provide periodic reports on Transporter's Internet Web Site (web site) 
      as to any changes in the condition that prompted the OFO and probable 
      duration of the OFO.  OFOs affecting multiple Shippers on all or any 
      portion of Transporter's System will be posted on the web site.  The OFO 
      will be posted within one (1) hour of its issuance and will be effective 
      within four (4) hours of issuance.  To the extent an OFO is only 
      applicable to specific Shippers, Transporter may notify such Shippers by 
      telephone or facsimile, but the OFO will be effective as to such 
      Shippers when posted on Transporter's web site.  Shipper must make a 
      contact person available on a twenty-four (24) hour basis to receive OFO 
      notices, and provide all necessary information to Transporter.  
      Transporter will use reasonable efforts to give actual notice to that 
      person, as time permits.
================================================================================



7.2   COMPLIANCE WITH OPERATIONAL FLOW ORDERS - OFOs issued to alleviate 
      conditions that threaten the operational integrity of Transporter's 
      System will require compliance within four (4) hours of issuance, or 
      such other time specified in the OFO.  Any Shipper receiving an OFO must 
      undertake such of the following actions as are necessary to comply with 
      such order:
   
      a.    Commence or increase tenders of Gas into Transporter's System by a 
            specified quantity at specified Receipt Points or shift tenders of 
            Gas, in whole or in part, to different specified Receipt Points;
   
      b.    Cease or reduce tenders of Gas into Transporter's System by a 
            specified quantity at specified Receipt Points;
   
      c.    Commence or increase takes of Gas from Transporter's System by a 
            specified quantity at specified Delivery Points or shift takes of 
            Gas, in whole or in part, from different Delivery Points;
   
      d.    Cease or reduce takes of Gas from Transporter's System by a 
            specified quantity at specified Delivery Points.
   
7.3   PENALTIES - If Shipper is notified by Transporter of an OFO and fails to 
      comply with such OFO during the effective period of the OFO, Shipper 
      shall be subject to a penalty for quantities received and/or delivered 
      in excess of the quantities specified by Transporter in such OFO.  If 
      Shipper complies by adjusting its tenders or takes within the time 
      period specified in an OFO, Shipper shall not be subject to the penalty 
      set forth in this Subsection 7.3.  Shipper compliance will be a change 
      in Gas flow to the level specified by Transporter and will be evidenced 
      by the confirmation of a flow rate change from an upstream or downstream 
      Operator or the confirmation of a flow rate change by Transporter.  
      Transporter will use reasonable efforts to assist any Shipper in 
      complying with an OFO.
================================================================================



      Penalties for failure to comply with an OFO will be assessed according 
      to the following schedule.

      ------------------------------------------------------------------
      100% Compliance                                       $     0.00/dt

      ------------------------------------------------------------------

 Transporter will refund or carry forward, for each calendar Year, any 
 difference between the penalty revenues received by Transporter and the costs 
 incurred by Transporter as a result of failures of Shippers to comply with 
 OFOs.  To the extent the difference between costs and revenues in respect of 
 such OFO penalties during any calendar Year is less than Four Hundred 
 Thousand Dollars ($400,000), Transporter shall carry forward the difference 
 to the next calendar Year.  To the extent the difference is greater than Four 
 Hundred Thousand Dollars ($400,000), Transporter shall refund or invoice each 
 System Shipper in proportion to such Shipper's use of the System during such 
 calendar Year within one hundred twenty (120) Days after the end of the 
 calendar Year.  Any such difference, whether a positive or negative, shall 
 include interest at the rate set forth in section 154.501 of the Commission's 
 regulations.

      Transporter will postpone the issuance of an OFO, if feasible, a
