                         provided, however, that Transporter will not be
                         obligated to accept any offer for transportation
                         service at less than Transporters maximum authorized

                      Rate to be paid over the term of the proposed service

                                                maximum rate

                                     i = monthly equivalent of
                                     Transporter's approved overall
                                     rate of return

                   some or all of the service performed under this Rate
                   Schedule, so long as such discounting is necessary to meet
                   competitive conditions existing at the time; provided,
                   however, that in no event shall rates charged under this Rate

                   Transportation Demand Rates and Minimum Transportation
                   Commodity Rates for firm reserved service. Transporter shall
                   not be obligated to offer service at discount rates; however,
                   to the extent such discounted service is offered, it shall be
                   offered on a non-discriminatory basis. For each transaction

                   4.4 Discounted Rates. For purposes of administering rates
                   under this Rate Schedule ITS Transporter shall have the right
                   to discount the Maximum Transportation Commodity Rates for

                   services performed under this Rate Schedule, so long as such
                   discounting is necessary to meet competitive conditions
                   existing at the time; provided, however, that in no event
                   shall rates charged under this Rate Schedule be less than

                   extent such discounted service is offered, it shall be
                   offered on a non-discriminatory basis. For each transaction
                   discounted pursuant to this provision, the amount of the
                   discount shall be apportioned among the

                   service. Park and Loan service provided hereunder is of a
                   lower priority than transportation provided pursuant to Rate
                   Schedules RTS and ITS and is subject to curtailment or
                   interruption as Transporter deems necessary.

                   2.2 Park and loan services available under this Rate Schedule
                   include:

                        (a) Parking Service. Parking Service shall consist of
                        (i) Transporters receipt of natural gas tendered by
                        Shipper for parking service (Parked Quantity); (ii) the
                        holding of the Parked Quantity for Shippers account at
                        the point (s) specified in Shippers nomination (Parking
                        Point (s)), and (iii) Transporters redelivery of the
                        Parked Quantities to Shipper, or for Shippers account,

                        Transporters advancement (loan) of the quantity of
                        natural gas nominated by Shipper (Loaned Quantity), up
                        to the Maximum Balance Quantity specified in Shippers
                        Park and Loan Service Contract, at the point (s)
                        specified in Shippers nomination (Loan Point (s)); and

              3.   ACCOUNT BALANCES; TRANSPORTATION; ASSIGNMENTS

                   3.1 Transporter shall establish an account for each Shipper
                   using this service which reflects the Parked Balance at each
                   Parking Point and the Loan Balance at each Loan Point.
                   Whenever Transporter receives Parked Quantities from, or
                   delivers Loaned Quantities to, a Shipper the quantities
                   received or delivered will be reflected in the Shippers
                   Parked Balance or Loan Balance, as appropriate, for the Park
                   or Loan Point at which they were received or delivered,
                   Transporter will credit the Shippers account to reflect the
                   new balance.

                        and loan capacity available, solely for the purpose of
                        calculating the Balance Charge, Transporter shall reduce
                        the Parked Balance or Loan Balance for each such day by

                        Loan Balance subject to a Balance Charge will not be
                        reduced if Transporter is unable to honor park and loan
                        nominations because transportation service has been
                        nominated for parked and loaned quantities and there is
                        inadequate interruptible transportation capacity
                        available.

                   under this Rate Schedule PAL, Transporter shall have the
                   right to discount the Maximum Injection / Withdrawal Rate and
                   Maximum Daily Balance Rate for park and loan service under
                   this Rate Schedule PAL and to charge a lower rate for some or
                   all of the services performed under this Rate Schedule,
                   provided that such discounting is necessary to meet
                   competitive conditions existing at the time; provided,
                   however, that in no event shall rates charged under this Rate
                   Schedule be less than the Minimum Injection/ Withdrawal Rate
                   and Minimum Daily Balance Rate reflected on the currently
                   effective Sheet No. 5 of the FERC Gas Tariff. Transporter
                   shall not be required to offer park and loan service at a
                   discount rate; however, to the extent such discounted service
                   is offered, it shall be offered on a nondiscriminatory basis.

                   existing Parked Balances and/or Loan Balances over the period
                   specified in the notice. Such notices may be provided by

                   Transporter's Electronic Bulletin Board. Such

<PAGE>

                   notices shall be issued to Shippers in order based upon the
                   net aggregate of each Shipper's outstanding balance at all
                   Parking and Loan Points beginning with the largest balance.
                   The minimum period of time for elimination or reduction of
                   balances that can be stated in such a notice is the end of
                   the gas day for which the next available nomination deadline
                   applies.

                   6.2 If Shipper fails to comply with a notice given in
                   accordance with Section 6.1 above, Transporter shall cash out
                   the balance quantity that Shipper was advised, but failed, to
                   reduce or eliminate at the replacement cost of gas plus ten
                   percent (10%) for Loan Balances or the sale price of the gas
                   less ten percent (10%) for Parked Balances. For the purposes
                   of the preceding sentence, the replacement cost and sale
                   price of gas shall be computed as follows: (i) all balances

                   any day to or on behalf of Shipper at one or more
                   Delivery Point(s), which quantity shall be the thermal
                   equivalent of the Input Quantity delivered to
                   Transporter at the Receipt Point(s) by or on behalf of
                   Shipper on that day, adjusted by the applicable
                   Measurement Variance/Fuel Use Quantity (unless, in the
                   case of a positive Measurement Variance/Fuel Use Factor,
                   Shipper provides the applicable Measurement
                   Variance/Fuel Use Quantity to Transporter at the Receipt
                   Point).

                   established pursuant to the Gas Transportation Contract
                   between Shipper and Transporter; provided, however, that (i)
                   the aggregate total of such Shipper's Scheduled Equivalent
                   Quantities on any day at any Delivery Point may not exceed
                   the Maximum Equivalent Quantity, and (ii) the total quantity
                   of gas nominated by Shipper to be transported by Transporter
                   on any day through any single segment of Transporter's
                   pipeline system may not exceed the Maximum Equivalent
                   Quantity. For purposes of this section, a segment of
                   Transporter's pipeline system is the portion of Transporter's
                   system located between any Delivery Point and the nearest
                   upstream or downstream Receipt Point.

              2.26 Fuel Calculation Mechanism -- In Kind Fuel Reimbursement.
              When the fuel reimbursement method is fuel in-kind, the results of
              the fuel reimbursement calculations for the nomination process
              should be rounded to the nearest dekatherm or gigajoule (Canada).
              The standard fuel calculation mechanism, as this is related to the
              nomination process, should be (1-fuel %/100) multiplied by receipt
              quantity = delivery quantity. Transporter will not reject a
              nomination for reasons of rounding differences due to fuel
              calculation of less than 5 Dth, and Transporter will provide, if
              applicable, a fuel matrix for receipt and delivery point
              combinations. The Service Requester will not be responsible for
              calculating and totaling fuel based on each zone or facility
              traversed. For current in- kind fuel reimbursement procedures,
              fuel rates should be made effective only at the beginning of the
              month. "Fuel" as referred to in this calculation refers to the
              Measurement Variance/Fuel Use Factor as defined further in Section
              2.27.

 Sheet        Transporter shall use the applicable Measurement
 No. 49       Variance/Fuel Use Factor to adjust a Shippers Equivalent
              Quantity, up to the Maximum Equivalent Quantity, or to calculate
              the Measurement Variance/Fuel Use Quantity that a Shipper may
              tender at the Applicable Receipt Point in lieu of an adjustment to
              the Equivalent Quantity. A positive Measurement Variance/ Fuel Use
              Factor represents a loss in Transporter's Measurement
              Variance/Fuel Use. A negative Measurement Variance/Fuel Use Factor
              represents a net gain in Transporter's Measurement Variance/Fuel
              Use. As provided by

              the formula for calculating the Measurement Variance/Fuel Use
              Factor, different Measurement Variance/Fuel Use Factors will be
              applied to Transportation within Zone 1 and Zone 2 and for
              backhauls.

              Where a negative Measurement Variance/Fuel Use Factor exists,
              additional units of gas associated with such negative Measurement
              Variance/Fuel Use Factor which are within the Shipper's Maximum
              Equivalent Quantity can be transported using the commodity rate
              under Transporter's RTS Rate Schedule. If the additional units of
              gas associated with such negative Measurement Variance/Fuel Use
              Factor exceed the Shipper's Maximum Equivalent Quantity, those
              additional units may be transported under the ITS Rate Schedule at
              a rate up to the maximum rate for such service on the currently
              effective Sheet No. 4 of this FERC Gas Tariff.

                   pre-qualified bidders. To remain on this list, a prospective
                   bidder must update the information required by Section 3.4 of
                   this Tariff on an annual basis. Based on a subsequent review
                   of the prospective bidder's financial status, Transporter may
                   delete a pre-qualified bidder from its list of pre-qualified
                   bidders or may amend that list with respect to any
                   limitations on credit. All of the provisions of Section 3 of

 Sheet             Such nominations are to be provided to Transporter under
No. 57A            the timeline set forth in Section 4.8 either
                   electronically by posting on Transporter's Electronic
                   Bulletin Board or via Electronic Date Interchange ("EDI").
                   All such postings for nomination purposes shall comply with
                   all format and protocol requirements specified by
                   Transporter.

                   Transporter may allow Shipper to submit a nomination or
                   Intra-day nomination in writing or by facsimile during the 30
                   days following commencement of service under Shipper's first
                   contract with Iroquois, or in the event of failure of
                   electronic communication equipment, Internet or third party
                   service provider, or other similar emergency event, provided,
                   however, that Transporter may require Shipper to provide
                   documentation of such event by an affidavit within 24 hours
                   of such event.

                   All nominations shall be considered original nominations and
                   must be replaced to be changed. When a nomination for a date
                   range is received, each day within the range is considered an
                   original nomination. When 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.

                   Transporter shall support a seven-days-a-week, twenty-
                   four-hours-a-day nomination process. Personnel may be reached
                   by beeper after normal business hours.

                   All nominations should include shipper defined begin dates
                   and end dates. All nominations, excluding intra-day
                   nominations, should have roll-over options.

 Sheet             Specifically, Shippers should have the ability to

No. 57B            nominate for several days, months, or years, provided
                   the nomination begin and end dates are within the term
                   of Shipper's contract.

                   The standard quantity for nominations, confirmation and
                   scheduling is dekatherms per gas day in the United States,
                   gigajoules per gas day in Canada and gigacalories per gas day
                   in Mexico. (For reference 1 dekatherm = 1,000,000 Btu's; 1
                   gigajoule = 1,000,000,000 joules; and 1 gigacalorie =
                   1,000,000,000 calories.) For commercial purposes, the
                   standard conversion factor between dekatherms and gigajoules
                   is 1.055056 gigajoules per dekatherm and between dekatherms
                   and gigacalories is 0.251996 gigacalories per dekatherm. The
                   standard Btu is the International Btu, which is also called
                   the Btu(IT); the standard joule is the joule specified in the
                   SI system of units.

                   4.2   Allocation of Capacity.
                   On each day Transporter shall determine with respect to all
                   contracts:
                        (a)   the total quantities which all Shippers have
                        nominated to be received for transportation service
                        on that day;

                        (b)   the total quantities which all Shippers have
                        nominated to be delivered for transportation
                        service on that day;

                        (c) the twenty-five (25) MDT of system linepack reserved
                        for unscheduled imbalances with point operators
                        receiving service under Operational Balancing Agreements
                        ("OBAs");

                        (d)   the total quantities which all Shippers have
                        nominated to be parked and loaned on that day; and

                        (e) Transporter's system capacity available in each
                        pipeline segment to perform all of the requires
                        services.

                   When allocating capacity, the transportation priority for
                   fuel will be the same as the level of service as the
                   transaction to which it applies.

                   each Gas Transportation Contract and/or Park and Loan Service
                   Contract with said Shipper. Forthwith after receiving such
                   advice from Transporter, Shipper may provide an Intra-day
                   nomination to Transporter which shall be no greater than the
                   service available for each Receipt and Delivery Point or
                   Parking and Loan Point. The least of Shipper's original

                   Shipper's Intra-day nomination for each Receipt and Delivery

                   and Scheduled Equivalent Quantity, respectively, for such
                   Receipt and Delivery Point, or (2) the Injection Quantity or
                   Withdrawal Quantity for such Parking Point or Loan Point.
                   Shipper shall arrange for the Scheduled Input Quantity to be
                   delivered to Transporter at each Receipt Point on such day.

 Sheet             At the end of each gas day, Transporter should provide
No. 59B            the final scheduled quantities for the just completed
                   gas day. With respect to the implementation of this process
                   via the 1.4.x scheduled quantity related standards,
                   Transporter should send an end of gas day Scheduled Quantity
                   document. Receivers of the end of gas day Scheduled Quantity
                   document can waive the Transporter's sending of the end of
                   gas day Scheduled Quantity document.

                   4.4 Late Nominations. Requests for service received after the
                   nomination deadlines set forth in Section 4.8 shall be
                   considered Late Nominations. Late Nominations will be
                   accommodated if they do not interfere with operation of
                   Transporter's system or Transporter's ability to render other
                   scheduled service. In the event capacity remains available on
                   Transporter's system after service has been nominated and
                   scheduled in accordance with Sections 4.1, 4.2, 4.3 and 4.4
                   above, or capacity becomes available either (i) due to
                   requests from Shippers which have previously scheduled
                   service to change such scheduled service, or (ii) due to
                   operational or weather situations which permit Transporter to
                   render additional service without compromising service
                   already scheduled, Transporter will accept Late Nominations
                   and shall endeavor, but shall not be obligated, to provide
                   service which implements such Late Nominations.

 Sheet             4.5   Pooling. If requested by a Shipper or supplier on
 No. 60            Transporter's system, Transporter will offer at least
                   one pool. Deliveries from Receipt Points should be able to be
                   delivered directly into at least one pool, and Delivery
                   Points should be able to receive quantities from at least one
                   pool, excluding non-contiguous facilities.

                   4.6 Intra-day Nominations. An Intra-day nomination is a
                   nomination submitted after the nomination deadline whose
                   effective time is no earlier than the beginning of the gas
                   day and runs through the end of that gas day. Intra-day
                   nominations may be used to nominate new supply or market.
                   Intra-day nominations can be used to request increases or
                   decreases in total flow, changes to receipt points, or
                   changes to delivery points of scheduled gas. All nominations,
                   including Intra-day nominations, should be based on a daily
                   quantity; thus, an intra-day nominator need not submit an
                   hourly nomination. Intra-day nominations should include an
                   effective date and time. The interconnected parties should
                   agree on the hourly flows of the Intra-day nomination, if not
                   otherwise addressed in Transporter's contract or tariff.
                   Intra-day nominations do not rollover (i.e. Intra-day
                   nominations span one day only). Intra-day nominations do not
                   replace the remainder of a standing nomination. There is no
                   need to re-nominate if Intra-day nomination modifies existing
                   nomination.

No. 60A       nomination/confirmation process 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.

              (ii) With respect to the processing of requests for increases
              during the intraday nomination/confirmation process, 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.

              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

 Sheet        (iv)   With respect to 1.3.22 i, ii, and iii, if there is no
No. 60B       response to a Request for Confirmation or an unsolicited
              Confirmation Response, the Transporter shall provide the Shipper
              with the following information to explain why the nomination
              failed, as applicable:

                   (1) the Transporter did not conduct the confirmation;
                   (2) the Shipper is told by Transporter that the upstream
                   confirming party did not conduct the confirmation;
                   (3) the Shipper is told by Transporter that the upstream
                   Service Requester did not have the gas or submit the
                   nomination;
                   (4) the Shipper is told by Transporter that the downstream
                   confirming party did not conduct the confirmation;
                   (5) the Shipper is told by Transporter that the downstream
                   Service Requester did not have the market or submit the
                   nomination. This information should be imparted to the
                   Shipper on the Scheduled Quantity document.

              Elapsed-prorated-scheduled quantity means that portion of the
              scheduled quantity that would have theoretically flowed up to the
              effective time of the intraday nomination being confirmed, based
              upon a cumulative uniform hourly quantity for each nomination
              period affected.

No. 60B.01       The Explicit Confirmation process requires that the Confirming
                 Party respond to a Request for Confirmation or initiate an
                 unsolicited Confirmation Response. Absent
<PAGE>

                 mutual agreement to the contrary, Explicit Confirmation is the
                 default methodology.

                 When a previously confirmed and scheduled quantity is altered,
                 notification of such alteration should be provided to all of
                 the below that are affected: 1) Confirmation Requester in a
                 Confirmation Response (or unsolicited Confirmation Response as
                 applicable) document by the Confirming Party; 2) Confirming
                 Party in a Request for Confirmation document by the
                 Confirmation Requester; 3) Shipper(s) in a Scheduled Quantity
                 document by the applicable Confirming Party or Confirmation
                 Requester on whose system the Shipper(s) nomination(s) were
                 made.

                 Applicable notification(s) of such alterations should be
                 provided to the affected parties reasonably proximate in time
                 to the time during which the event causing the alteration was
                 acted upon by the Confirmation Requester or Confirming Party,
                 respectively. With respect to the implementation of this
                 process via the 1.4.x standards, Confirming Parties should send
                 the applicable document(s) to the applicable party(ies) no
                 later than the next time they are slated to communicate
                 confirmations or scheduled quantities (as applicable.)

                 When a Confirmation Requester receives a Confirmation Response
                 document from a Confirming Party by the conclusion of a given
                 quarter hour period, the Confirmation Requester will send to
                 the Confirming Party's designated site a corresponding
                 Confirmation Response Quick Response document by the conclusion
                 of the subsequent quarter hour period. The quarter hour periods
                 will be defined to begin on the hour and at 15, 30, and 45
                 minutes past the hour. A given quarter hour will contain all
                 transactions whose receipt time is less than the beginning of

                 Confirming Parties' nightly processing and routine maintenance
                 occurring outside of normal business hours are apt to interrupt
                 the normal schedule of confirmations/quick response turnaround
                 stated above. Such delays should be kept to a minimum. The

 Sheet             (v)   For purposes of Section 4.8 (ii) (iii) and (iv),
No. 60D            "provide" shall mean, for transmittals pursuant to
                   standards 1.4.x, receipt at the designated site, and for
                   purposes of other forms of transmittal, it shall mean send or
                   post.

                   With the exception of otherwise stated GISB nominations
                   deadlines, when a Transporter receives a Nomination document
                   from a Shipper by the conclusion of a given quarter hour
                   period, the Transporter will send to the Shipper's designated
                   site a corresponding Quick Response document by the
                   conclusion of the subsequent quarter hour period.

                   The quarter hour periods will be defined to begin on the hour
                   and at 15, 30, and 45 minutes past the hour. A given quarter
                   hour will contain all transactions whose receipt time is less
                   than the beginning of the subsequent quarter hour.

                   Transporter's nightly processing and routine maintenance
                   occurring outside of normal business hours are apt to
                   interrupt the normal schedule for nominations/quick response
                   turnaround stated above. Such delays should be kept to a

                   earliest opportunity and no later than the start of normal
                   working hours the following day, seven days per week.

              4.9 Bumping. Any Shipper who is bumped pursuant to Section 4.8
              shall be directly notified by Transporter at their primary
              telephone or facsimile number, as designated by Shipper, as well
              as through Internet e-mail. Upon request of Shipper, Transporter
              shall endeavor, but shall not be obligated, to notify Shipper at
              alternate numbers. Bumping that affects transactions on multiple
              transporters should occur at grid-wide synchronization times only.
              The daily grid-wide synchronization times for scheduled flow are
              9:00 a.m., 5:00 p.m., and 9:00 p.m.

                    Shippers receiving park and loan service under the PAL Rate
                    Schedule or point operators receiving service under OBAs
                    which have requested more than 250 Dth day. Such services
                    shall be divided into two categories: those which increase
                    linepack and those which decrease linepack. Within each
                    category, to the extent necessary, Transporter will curtail
                    service to those Customers whose nominations and requests
                    adversely impact the operations of Transporter's system in
                    the reverse order in which such nominations and requests
                    were received; provided, however, that the last 25 MDT of
                    linepack flexibility available for park and loan service
                    will be reserved for unscheduled requests by point operators
                    that receive service under OBAs. Nominations or requests of
                    250 Dth or less shall be curtailed after all other
                    nominations for park and loan service and requests by point
                    operators receiving service under OBAs Balancing Agreements.

                    (b) Second, Transporter shall curtail service to those
                    Shippers receiving Service under the ITS Rate Schedule
                    paying the lowest percentage of the Maximum Commodity Rate
                    for the service being provided.

                    (c) Third, Transporter shall curtail service to those
                    Shippers receiving Service under the ITS Rate Schedule
                    paying the maximum rate for service on a pro rata basis.

                    (d) Fourth, Transporter shall curtail service to those
                    Shippers receiving service under the RTS Rate Schedules at
                    Alternate Receipt and Delivery Point(s) pursuant to Gas
                    Transportation Contracts for Firm Reserved Service under
                    Part 284 of the Commission's Regulations on a pro-rata
                    basis.

                        Section 5, Transporter will assess the value of a
                        Negotiated Rate or a rate under a Negotiated Rate
                        Formula in accordance with the provisions of Section 32

              6.   BALANCING AND PENALTY PROVISIONS

              With respect to transportation services, Shipper shall endeavor to
              monitor and, if necessary, adjust deliveries and receipts of gas
              in order to maintain a daily balance of deliveries and receipts.
              Transporter shall not be obligated to receive or make available
              gas in excess of the Scheduled Input Quantities, nor shall
              Transporter be obligated to deliver to Shipper at the Delivery
              Point(s) quantities in excess of Scheduled Equivalent Quantities.
              Transporter will monitor, to the best of its ability, deliveries
              and receipts for each transportation transaction and, based upon
              information available, advise Shipper of any imbalance situation
              which has occurred or may occur unless corrective action is taken.
              Upon notification, Shipper shall endeavor to adjust deliveries and
              receipts to avoid any imbalance. Any adjustment to deliveries and
              receipts by Shipper, whether or not pursuant to notification from
              Transporter, shall be coordinated with Transporters Gas
              Transportation Department and in accordance with the scheduling
              procedures set forth in Section 4 above.

              If Shipper fails to maintain a balance of deliveries and receipts
              or inaccurately schedules deliveries and receipts, Transporter
              shall impose one or more of the imbalance or scheduling charges
              set forth in this section, as applicable.

  Sheet
 No. 62             6.1   Scheduling Penalty
                         (a) Receipt Point Scheduling. If on any day Shipper
                         delivers a quantity of gas to Transporter at any
                         Receipt Point which exceeds or falls short of the
                         Scheduled Input Quantity for such Receipt Point by the
                         greater of ten percent (10%) or 400 Dth, then Shipper
                         shall pay to Transporter an amount equal to the Maximum
                         Transportation Commodity Rate for service under the ITS
                         Rate Schedule for service to the zone in which the gas
                         is scheduled to be delivered for all quantities in
                         excess or which fall short of the Scheduled Input

                         Receipt Point. Transporter may waive the penalty on a
                         basis which is not unduly discriminatory if, in the
                         exercise of its reasonable discretion, Transporter
                         determines that such excess or shortfall will not cause
                         operational difficulties or affect the integrity of

                         (b) Delivery Point Scheduling. If on any day Shipper
                         takes delivery of a quantity of gas from Transporter at
                         any Delivery Point which exceeds or falls short of the
                         Scheduled Equivalent Quantity for such Delivery Point
                         by the greater of ten percent (10%) or 400 Dth, then
                         Shipper shall pay to Transporter an amount equal to the
                         Maximum Transportation Commodity Rate for service under
                         the ITS Rate Schedule for service to the zone in which
                         the gas is scheduled to be delivered for all quantities
                         in excess or which falls short of the Scheduled
                         Equivalent Quantity by more than the greater of ten
                         percent (10%) or 400 Dth of the Scheduled Equivalent
                         Quantity for such Delivery Point. Transporter may waive
                         the penalty on a basis which is not unduly
                         discriminatory if, in the exercise of its reasonable
                         discretion, Transporter determines that such excess or
                         shortfall will not cause operational difficulties or
                         affect the integrity of Transporters system or
                         Transporters ability to render other scheduled service
                         on such day.

                         (c) On any day on which Shipper may be liable for
                         Scheduling Penalties under both Sections 6.1 (a) and
                         6.1 (b) above, Transporter shall impose on Shipper only
                         the greater of the two penalties.

                        four percent (4%) of the Equivalent Quantities
                        taken by Shipper at the Delivery Point (s),
                        Transporter shall provide Shipper forty-eight hours
                        notification, or such lesser period of time as
                        reasonably required by Transporter to protect the
                        integrity of its system, to initiate corrective
                        action. In the event Shipper fails to initiate the
                        corrective action mutually agreed upon by Shipper
                        and Transporter's Gas Transporter shall charge
                        Shipper $.75 per Dth for any receipts which are in

                        (4%) or 400 Dth of Deliveries. Shipper shall have
                        45 days after notification to reduce the cumulative
                        imbalance to zero.

                        (b) Monthly Balancing. At least seven (7) days prior to
                        the end of each month Transporter will notify Shipper if
                        it appears that Receipts (less Measurement Variance/
                        Fuel Use Quantities) will be in excess of or deficient
                        by four percent (4%) or more of Deliveries. In the event
                        Shipper fails to agree upon the appropriate corrective
                        action to be implemented with Transporter's
                        Transportation Department within two (2) Gas Days after
                        notification, and / or fails to implement the corrective
                        action agreed upon, Transporter shall charge Shipper
                        $.75 per Dth for any Receipts (less Measurement
                        Variance/ Fuel Use Quantities) which are in excess of or
                        deficient by four percent (4%) of Deliveries.

                        Imbalances for any month that become apparent after the

                   6.4   Predetermined Allocation Method.

                              (a) Transporter may negotiate and enter into OBAs
                        with interstate pipelines, intrastate pipelines and
                        other entities. Transporter will not utilize
                        pre-determined allocations ("PDA") if Transporter has an
                        OBA in effect for a point. No difference balanced
                        in-kind shall be allocated to any Shipper at the Receipt
                        or Delivery Points covered by the OBA. PDA elements
                        should be

<PAGE>


                        standardized. Only one PDA allocation methodology
                        should be applied per allocation period.

                              (b) As used in this Section 4, a PDA is an
                        agreement by or among point operators, prior to the
                        beginning of the gas day, at a Receipt or Delivery Point
                        to allocate the difference between the scheduled daily
                        quantity and the actual daily flow of gas in a mutually
                        agreeable manner. Types of allocation methods include,
                        but are not limited to, ranked, pro rata, percentage and
                        swing. PDAs shall be provided by the interconnecting
                        operator, and for multi-tiered allocations, may be
                        provided by the upstream title holders or Shippers.
                        Interconnecting operators at Receipt Points shall
                        provide a PDA to allocate to upstream title holders.
                        Upstream title holders may provide a PDA to allocate to
                        the parties taking possession of their gas at a Receipt
                        Points. Shippers may provide a PDA to allocate to their
                        nominations at either Receipt or Delivery Points. Two
                        welded parties should agree on who submits a PDA
                        methodology and who allocates at the point before gas
                        flows. 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 start of gas day. The allocating
                        party should send back "confirmation" of receipt of the
                        pre-determined allocation within 15 minutes.

                              (c) If confirming parties cannot agree upon an
                        allocation methodology, "pro rata based upon confirmed
                        nominations" shall be used as the default method.

                   multiple Shippers at a common Receipt or Delivery Point in
                   which the quantities received or delivered exceed or fall
                   short of the sum of the Scheduled Input or Scheduled
                   Equivalent Quantities for such day, Shippers whose volumes
                   are commingled at such Delivery or Receipt Point shall have
                   the obligation to inform Transporter as to the allocation of
                   such volumes. Transporter shall allocate volumes in
                   accordance with Operational Balancing Agreements with the
                   operator of the common Receipt or Delivery Point to the
                   extent Operational Balancing Agreements are in effect at such
                   points.

                   6.5 Penalty Provisions Inapplicable. No monthly imbalance
                   charge shall be assessed unless Transporter has notified
                   Shipper that an imbalance has occurred or will occur without

 No. 65            effective OBA, Transporter shall promptly notify all
                   Shippers via posting on its Electronic Bulletin Board, and
                   will provide written notification of the giving or receiving
                   of such notice to the affected shippers by fax or overnight
                   mail. In any month in which Shipper may be liable for both
                   Daily and Monthly Imbalance Penalties, the sum of the excess
                   and deficiency quantities for which Shipper has been assessed
                   a Daily Penalty shall be deleted from excess or deficient
                   quantities used in calculating the monthly penalty. In
                   calculating excess and deficient quantities, Transporter
                   shall take into consideration (1) make-up quantities used
                   pursuant to Transporter's notification to correct any excess
                   or deficiency in receipt and deliveries and (2) for purposes
                   of assessing imbalance charges, any offsetting excess or
                   deficiency in deliveries under other transportation contracts
                   between Transporter and Shipper.

                   6.6 Penalty Provisions Not Exclusive. Nothing in this Section
                   6 shall limit Transporter's right to take such action as may
                   be required to adjust deliveries and receipts in order to
                   alleviate conditions which threaten the integrity of its
                   system, nor prevent Transporter from exercising any other
                   legal remedies which may be available.

                   6.7 Crediting of Overrun Penalty Revenues. In the event that
                   Transporter assesses and collects overrun penalties in
                   accordance with the provisions of this Section 6, such
                   revenues, in excess of Transporter Overrun Costs, (such
                   excess revenues herein referred to as "Excess Overrun
                   Revenues") shall be credited to the bills of Rate Schedule
                   RTS Shippers who did not receive scheduled service as a
                   result of the associated overruns. If more than one Rate
                   Schedule RTS Shipper was unable to receive scheduled service
                   as a result of such overruns, then the Excess Overrun
                   Revenues shall be credited among such Shippers based on the
                   ratios of the scheduled quantity of gas each Shipper was

 No. 71        10.   MEASUREMENT

               The volume and the total heating value of the gas delivered to
               Transporter at the Receipt Point(s) and made available to or on
               behalf of Shipper at the Delivery Point(s) shall be determined
               as follows:

                    10.1   Unit of Measurement. The unit of gas, for the
                    purpose of measurement, shall be one (1) Mcf.

                    10.2 Heating Value Per Cubic Foot. The total heating value
                    of the gas per cubic foot shall be determined for any month
                    by taking the weighted average of the heating values as
                    recorded each day by a calorimeter or as determined by
                    chromatographic analysis of a sample of gas collected daily
                    during the month, or any other method mutually agreed upon
                    by Shipper and Transporter.

                    10.3 Determination of Dekatherms Delivered. The dekatherms
                    delivered shall be determined by multiplying the Mcf
                    delivered by the ratio of the Btu per cubic foot delivered
                    to 1,000. For purposes of this determination, the specific
                    gravity and heating value shall be determined at
                    approximately the same time.

                    10.4 Determination of Temperature. The temperature of the
                    gas passing through each meter shall be determined for any
                    day by the continuous use of a recording thermometer so
                    installed that it may properly record the temperature of the
                    gas flowing through each meter. The arithmetical average of
                    the temperature recorded each day shall be used in computing
                    gas quantities.
<PAGE>

                    10.5 Specific Gravity. The specific gravity of the gas shall
                    be determined by the use of a recording gravitometer, which
                    shall be checked at least once each month, or any other
                    method mutually agreed upon by Shipper and Transporter.

                    10.6 Deviation From Boyles Law. The deviation of the natural
                    gas from Boyles Law shall be determined by the use of the
                    table of formulas published by the American Gas Association
                    Par Research Project NX-19 corrected for carbon dioxide and
                    nitrogen, or any superseding applicable tables

                    amortization of a deferred regulatory asset (Deferred
                    Asset), comprised of the net of certain operating costs
                    and revenues related to the phasing in of Transporters
                    services during its initial year of operations, plus
                    associated carrying charges, as established and
                    approved by orders of the Federal Energy Regulatory
                    Commission, dated March 11, 1991, May 23, 1991, and
                    December 21, 1992, in Docket Nos. CP89-634-004, et al.
                    Transporter shall be entitled to amortize the beginning
                    Deferred Asset balance of $3,573,597 over a period of
                    nineteen (19) years commencing November 1, 1992.
                    Transporter shall file with the Federal Energy
                    Regulatory Commission revised tariff sheets and
                    supporting working papers to reflect changes in the
                    Deferred Asset Surcharge, in accordance with this
                    Section 12.3, to become effective November 1 of each
                    year during the 19-year amortization period.

                         (a) The Deferred Asset Surcharge shall be calculated on
                         an annual basis, for the 12-month period commencing
                         November 1, by dividing the Annual Requirement
                         allocated to each of Transporters Zones by the
                         corresponding Projected Throughput Quantity assigned to
                         such Zone, such that:

                         The Annual Requirement shall equal the sum of: (i)
                         $188,084, representing one years amortization of the
                         Deferred Asset; (ii) the aggregate of monthly carrying
                         charges for the surcharge year, computed in accordance
                         with paragraph (b) of this Section 12.3; and (iii) any
                         adjustment (positive or negative) representing the net
                         cumulative difference between each prior years Annual
                         Requirement, used as the basis for a previously
                         effective Deferred Asset Surcharge, and the

                         The Annual Requirement shall be allocated to
                         Transporters Zones pursuant to the interzone allocation
                         factors used in deriving Transporters then-effective
                         rates.

                         The Projected Throughput Quantity attributable to each
                         of Transporters Zones shall equal the product of (i)
                         the sum of the demand entitlements of all firm Shippers
                         for such Zone under long-term contracts (more than 30
                         days) as of the date of the filing; multiplied by (ii)
                         the applicable load factor used in deriving
                         Transporters then-effective rates.

 Sheet        12.5   Transportation Cost Rate Adjustment. Pursuant to the
No. 75C       Commission's Order issued on July 29, 1998 in Docket No.
              RP97-126, Transporter's base transportation rates (exclusive of
              all surcharges) set forth on Sheet No. 4 of this FERC Gas Tariff
              shall be periodically adjusted to reflect changes in charges
              incurred by Transporter for the transmission and compression of
              gas by others as reflected in Account No. 858 ("Account 858
              Costs"). On September 30 of each year Transporter shall file with
              the Commission a Transportation Cost Rate Adjustment (TCRA) to be
              effective each November 1 and applied to all maximum RTS and ITS
              rates as shown on Sheet No. 4 of this FERC Gas Tariff.

                   (a)   Determination of TCRA.

                        (i) The Current Transportation Costs (Demand and
                        Commodity) shall be Transporter's projected Account 858
                        Costs during the 12 months commencing with the effective

  Sub.                   GENERAL TERMS AND CONDITIONS (Continued)
Original
  Sheet             (ii)   The Current Transportation Cost Rates (Demand
 No. 75D            and Commodity) shall be determined by dividing the
                    Current Transportation Costs by Transporter's projected
                    billing determinants for the twelve months commencing with
                    the effective date of each TCRA filing. The Initial
                    Transportation Cost Rates shall be determined by dividing
                    the Initial Transportation Costs by the applicable billing
                    determinants reflected in the rate design underlying
                    Transporter's base transportation rates approved in Docket
                    No. RP97-126.

                    (iii) The current TCRA (Demand and Commodity) shall be
                    determined by subtracting the Initial Transportation Cost
                    Rates from the Current Transportation Cost Rates.

               (b)   Unrecovered 858 Cost Account. Transporter shall
               establish and maintain an Unrecovered Transportation Cost
               Account for the collection of Account 858 Costs as a
               sub-account of FERC Account No. 186.

                    (i) Each month the Unrecovered Transportation Cost Account
                    shall be (1) debited by Transporter's actual Account 858
                    Costs and (2) credited by actual Account 858 Cost
                    collections, determined by multiplying

<PAGE>

                   Transporter's Current Transportation Cost Rates times the
                   corresponding actual billing determinants.

                    (ii) The Unrecovered Transportation Cost Account shall be
                    debited or credited, as appropriate, to reflect any refunds
                    received by, or surcharges incurred by Transporter which
                    relate to its Account 858 Costs.

                    (iii) Each month the Unrecovered Transportation Cost Account
                    shall be debited (in the event of a debit balance) or
                    credited (in the event of a credit balance) with interest,
                    calculated in accordance with the procedures set forth in
                    Section 154.501(d) of the Commission's regulations, on the
                    prior month's ending balance.

                    (iv) For each annual TCRA filing Transporter shall adjust
                    the Current Transportation Costs to reflect the Unrecovered
                    Transportation Account Balance (either positive or negative)
                    as of the month ending four (4) months prior to the
                    effective date of the filing.

               (c) Termination of Provision. At such time as the provisions of
               the TCRA are terminated, (a) any net credit balance in the
               applicable Account No. 186 sub-account for Unrecovered
               Transportation Costs shall be refunded to Shippers under Rate
               Schedules RTS and ITS, or (b) any net debit balance shall be due
               and payable by Shippers under Rate Schedules RTS and ITS. Such
               credits or debits will be allocated to the affected Shippers in
               proportion to their applicable billing determinants during the
               preceding twelve months.

                        bill rendered to Shipper. Such Charge for Late Payment
                        shall be determined by multiplying (a) the unpaid
                        portion of the bill, by (b) the ratio of the number of
                        days from the due date to the date of actual payment to

                        bond, guaranteeing payment to Transporter of the amount
                        ultimately found due upon such bills after a final

                        has been overcharged or undercharged in any form

                        Transporter shall refund the amount of any such

 Sheet             17.2   Good Faith Estimates. At Transporters request,
 No. 81            any Shipper which has executed a Gas Transportation
                   Contract with Transporter wherein Transporter agrees to
                   transport gas on behalf of Shipper will furnish to
                   Transporter good faith estimates of the daily, monthly and
                   annual quantities of natural gas which Shipper desires
                   Transporter to transport for Shipper for at least two (2)
                   years in advance. Such estimates will be used for planning
                   purposes and will not substitute for the nomination
                   procedures outlined above. The information provided pursuant
                   to this section shall not be made available to Transporters
                   affiliates which are engaged in the marketing of gas unless

                   the Receipt or Delivery Point(s) or Parking or Loan Point(s)
                   for which Shipper is requesting service. If Shippers request
                   for transportation or park and loan service involves a
                   quantity which Transporter cannot meter with reasonable
                   accuracy at the requested Receipt or Delivery Point(s) or
                   Park and Loan Point(s), Transporter will promptly so inform
                   Shipper and advise Shipper of the minimum quantity that can
                   be metered with reasonable accuracy at the proposed Points.

                   18.2 Coordination With Other Parties. Shipper shall make all
                   necessary arrangements with other parties at or upstream of
                   the Receipt Point(s) or Parking Point(s) where natural gas

                   shall not be required to render transportation service on
                   behalf of Shipper in the event that all facilities necessary

                        under Section 18.4 (s) as soon as practicable after such
                        new or changed reimbursement becomes effective.

 No. 83        19.   CONSTRUCTION OF LATERAL FACILITIES POLICY

               Transporter may invest in lateral and appurtenant facilities
               necessary to increase service to existing Shippers or to allow
               Transporter to provide service to a new Shipper on a
               non-discriminatory basis under the following conditions:

                    (a) Annual service revenues generated from such new or
                    increased service shall be sufficient to at least equal the
                    cost of service associated with such facilities. Such cost
                    of service shall be calculated to include, without
                    limitation, the following:

                         (i)  the cost of service associated with transporting
                         gas to the proposed facilities on Transporters
                         mainline;

                         (ii) the incremental operating expenses Transporter may
                         incur in operating the proposed facilities, including
                         but not limited to administrative, operation and
                         maintenance, and ad valorem and other taxes consistent
                         with those reflected in Transporters most recent rate
                         filing;

                         (iii) the estimated capital cost of the proposed
                         facilities, which shall be calculated using the
                         following objective criteria: the cost of materials
                         shall be estimated based on recently obtained quotes
                         from major industry recognized materials sources, and
                         the cost of construction will be estimated based on
                         per-mile construction costs experienced by Transporter
                         during construction in areas with similar geographical,
                         geological and demographic characteristics, adjusted
                         for the year of the proposed construction and any
                         site-specific characteristics, which capital costs
                         shall be assumed to be depreciated over the life of the
                         proposed new service; and,

                        overall rate of return reflected in Transporters
                        most recent rate filing.

                   (b) The facilities will not increase or decrease Transporters
                   main line capacity or compromise the integrity of
                   Transporters pipeline system.

                   (c)   The necessary authorizations are obtained from
                   governmental bodies.

              Nothing in this policy statement shall require Transporter to file
              an application for a certificate of public convenience and
              necessity under Section 7 (c) of the Natural Gas Act. Nothing in
              this policy statement shall prevent Transporter from contesting an
              application for service filed pursuant to Section 7(a) of the
              Natural Gas Act. Transporter reserves the right to seek a waiver
              of the policy set forth herein, for good cause shown.

              20.   IMPAIRMENT OF DELIVERIES

                   20.1 Force Majeure. Service under this Tariff may be
                   interrupted or curtailed for reasons of force majeure, and
                   Transporter shall give Shipper notice as soon as reasonably
                   possible of such interruption or curtailment.

                   20.2 Routine Repair and Maintenance. Transporter shall have
                   the right to interrupt or curtail service in whole or in part
                   on all or a portion of its system from time to time to
                   perform routine repair, maintenance, and other construction
                   or testing procedures on Transporters system as necessary to
                   maintain operational capability on Transporters system or to
                   comply with applicable regulatory requirements. Transporter
                   shall exercise due diligence to schedule such activity so as
                   to minimize disruptions of service to Shippers.

                         Board a projection of routine repair, maintenance,
                         and other construction or testing procedures
                         scheduled for the upcoming year, from April 1
                         through March 31, which are likely to affect
                         Transporters System Capacity. Transporter may in
                         good faith modify the projected schedule in any
                         manner, at any time during such year, and will

                         the first day of each month, Transporter will post on
                         its Electronic Bulletin Board a schedule of repair,
                         maintenance and other construction or testing
                         procedures for such month which are likely to affect
                         Transporters System Capacity. Such notice will include
                         an estimate of the duration of the activity.
                         Transporter will have no liability if it must modify
                         the schedule or perform additional unscheduled routine
                         repair, maintenance and other construction or testing
                         procedures during the month.

                    20.3 Make-up Service. In the event interruption or
                    curtailment occurs, Shipper shall be given the opportunity
                    on a subsequent day or days to make-up such loss of service
                    provided that such make-up service shall not preclude or
                    interfere with the service priorities set forth in Section
                    4. In the event such make-up service is provided, Shipper
                    shall be obligated to pay the Transportation Commodity
                    Charge for such service under the applicable Rate Schedule.

                   Transporter shall be obligated to refund demand charges
                   collected from firm shippers applicable to days in which firm
                   service is interrupted, if and to the extent that Transporter
                   is reimbursed for such demand charges through insurance
                   proceeds and such shipper is not recompensed for such demand
                   charges through any other primary insurance. Such refunds
                   shall be computed by allocating to each firm shipper for
                   which service was interrupted a pro rata share of the
                   attributable insurance proceeds received by Transporter based
                   on the proportion that the eligible amount of each such

                   the eligible amounts of all such shippers

<PAGE>


                   affected demand charge payments. The affected demand charge
                   payments for each shipper shall be computed by multiplying
                   the daily applicable Transportation Demand Rate by the
                   quantity of gas not delivered by reason of the interruption
                   in firm service, not to exceed such shippers Maximum Input
                   Quantity. The eligible amount of such affected demand charge
                   payments shall be the portion of the affected demand charge
                   payments for which the shipper is not eligible to be
                   recompensed through other primary insurance. For purposes of
                   this paragraph, the applicable daily Transportation Demand
                   Rate applicable to the service that was interrupted by twelve
                   (12) and dividing the product by 365. Nothing herein shall

                   recompenses it, in whole or in part, for demand charges paid
                   on days when Transporter interrupts service.

                             posted on Transporter's Electronic Bulletin Board
                             subject to the requirements of Section 28.6(a);

                             (xiv) the date and time that bidding will cease
                             subject to the requirement of Section 28.6(a). Any
                             extension of the end date and time for accepting
                             bids will require that Releasing Shipper withdraw
                             the offer to release capacity and post a new
                             release with the extended end date and time;

                             (xv) whether the Releasing Shipper is willing to
                             release such capacity for a shorter period of time
                             and, if so, the minimum acceptable period of the
                             release; and

                             (xvi)   all other relevant terms of the
                             pre-arranged release.

                        (d) Once a Releasing Shipper has provided Transporter a
                        notice of its election to release capacity, such offer
                        shall be binding upon Releasing Shipper until
                        Transporter receives written or electronic notice of
                        withdrawal. The Releasing Shipper has the right to
                        withdraw its offer during the bid period where
                        unanticipated circumstances justify and no minimum bid
                        has been made. Assuming that Transporter has determined
                        that the Release Notice contains no deficiencies, once
                        the bidding period closes, the Releasing Notice shall
                        constitute a binding offer to release capacity to a
                        Successful Bidder(s) whose bid

                      accepting bids for such capacity from potential
                      Replacement Shippers. All potential bidders shall be
                      subject to the credit evaluation procedures provided
                      in Section 3 of this Tariff. Transporter shall not
                      accept a bid unless Transporter has verified the
                      creditworthiness of such bidder in accordance with
                      the provisions of Section 3, and unless bidder has
                      executed a blanket Gas Transportation Contract for
                      Replacement Shippers. All Shippers that wish to bid
                      on released capacity must notify Transporter via

 Sheet                  (g)   whether the bidder is willing to accept less
No. 101                 than the full amount of capacity released in the
                        event that there are two or more Successful Bidders and
                        Transporter must pro-rate the capacity in accordance
                        with Section 28.9(c) below; and

                        (h)   any other terms that may be relevant.

                   Once a potential Replacement Shipper has submitted a bid,
                   that bid shall be binding until Transporter receives a
                   written notice or electronic notice of withdrawal. Once the
                   bidding period closes, any bid posted on Transporter's
                   Electronic Bulletin Board shall constitute a binding offer to
                   enter into a Gas Transportation Contract for Firm Reserved
                   Service, subject only to the Releasing Shipper's decision to
                   accept a contingent bid. The bid shall be binding until (i)
                   Transporter selects the Successful Bidder (s), (ii)
                   Transporter determines that no bids satisfy the minimum terms
                   specified in the Release Notice; or (iii) contingencies have
                   been eliminated. Any contingency which has not been
                   eliminated prior to 3:00 p.m. Central Time on the specified
                   award date shall invalidate that bid. A bidder that withdraws
                   its bid during the bidding period may submit a higher bid
                   during the bidding period, but may not submit a lower bid.

                   28.9 Allocation of Released Capacity -- Transporter's
                   Criteria. Unless the Releasing Shipper specifies a different
                   criteria for evaluating bids in its Release Notice in
                   accordance with the provisions of Section 28.6 of this
                   Tariff, released capacity will be allocated best bid first,
                   until all offered capacity has been awarded, on a
                   non-discriminatory basis consistent with the

                        prearranged agreement with a prospective Prearranged
                        Replacement Shipper, Transporter will post notice of

                        accordance with the provisions of Section 28.7 above.
                        Transporter will evaluate all competing bids that

                        Shipper's failure to pay Replacement Demand Charges(s).

                        maximum rate transactions only, converting daily rate to
                        monthly rate is accomplished by multiplying the daily
                        rate times the number of days in the rate period,
                        dividing the result by the number of months in the rate

                        and rounding up or down to 4 decimal places. Converting
                        a monthly rate to a daily rate is accomplished by
                        multiplying the monthly rate by the number of months in
                        the rate period, dividing the result by the number of

 Second
 Revised            32.2   CAPACITY ALLOCATION AND CURTAILMENT
  Sheet
 No. 122            In determining the best bid for right of first refusal
                    and in allocating capacity, Transporter will consider
                    only revenues that would be generated by a demand or
                    reservation rate or other form of revenue guarantee,

<PAGE>

                    such as a usage charge associated with a minimum volume
                    commitment. In the event that the revenue generated
                    pursuant to the Negotiated Rate(s) or Negotiated Rate
                    Formula would exceed the revenue generated at the
                    Recourse Rate, for the purposes of capacity allocation
                    or curtailment, the Shipper paying such Negotiated Rate
                    or a rate under a Negotiated Rate Formula shall be
                    treated as if the rate equals the Recourse Rate. Any
                    Shipper, existing or new, paying the Recourse Rate has
                    the same right to capacity as a Shipper willing to pay
                    a higher Negotiated Rate or rate under a Negotiated
                    Rate Formula. If the Negotiated Rate or the rate under
                    a Negotiated Rate Formula is higher than the

                    Recourse Rate during certain portions of the relevant
                    evaluation period, but less than the revenue at the
                    Recourse Rate during other portions of the relevant
                    evaluation period (but the revenue pursuant to the

                    evaluated as though the Recourse Rate applied under
                    such bid, request or rate for the entire evaluation
                    period. Where the Negotiated Rate or rate under the
                    Negotiated Rate Formula results in revenue that is less
                    than the revenue at the Recourse Rate over the relevant

                    rates at the Negotiated Rate or rate under the

              consents shall not be unreasonably withheld. It is agreed,
              however, that the restrictions on assignment contained in this
              Article VII shall not in any way prevent either party to this
              Contract from pledging or mortgaging its rights hereunder as
              security for its indebtedness.

              Quantity, not to exceed the Maximum Equivalent Quantity for each
              Delivery Point as set forth on the currently effective CROR;

  Second      provided, however, that in the event that Transporter determines,

                   2. During the Term of this Contract, for each Dth per day of

              including any demand related fees, surcharges, and transition
              costs.

                   3. If Shipper is a Releasing Shipper, as defined in Section
              28 of the General Terms and Conditions, for each month, the
              Transportation Demand Charge billed to Shipper shall be credited
              in accordance with Section 4.3(h) of Rate Schedule RTS and Section
              28.17 of the General Terms and Conditions.

                   4. For each Dth of Scheduled Equivalent Quantity on any day,
              Shipper agrees to pay and shall pay the applicable GRI and ACA
              Adjustments, Deferred Asset Surcharge, and any other applicable
              surcharge specified in the RTS Rate Schedule as in effect on the
              day the transportation service is rendered.

                   5. Shipper agrees that Transporter shall have the unilateral
              right to file with the FERC and make changes effective in (a) the

              request the FERC to determine just and reasonable rates and/or
              terms or conditions of service for Transporter when Shipper

              rates may vary on a daily basis. For each Dth of the Parked
              Balance and Loan Balance to which a Discounted Daily Balance Rate
              applies, as set forth on Transporters Electronic Bulletin Board,

              Schedule PAL, or (b) any provision of the General Terms and
              Conditions applicable to such rate schedule. Transporter agrees
              that Shipper may contest any such filing or changes and may
              request the FERC to determine just and reasonable rates and/or
              terms or conditions of service for Transporter when it believes
              Transporters rates and/or terms or conditions of service may be
              unjust, unreasonable, unduly discriminatory or preferential.

Revised
 Sheet        How Blanket Capacity Release will work:
No. 193
              1)   Releasing Shippers will post available capacity on NrG
              Highway. Anyone with access to NrG will be able to read the
              notices of capacity. HOWEVER, ONLY THOSE SHIPPERS WHO HAVE:

                   --a fully executed Blanket Capacity Release Replacement
                   Shipper Contract; AND

                   --appropriate Financial Assurances in place; AND

                   --a fully-executed NrG Customer Use Agreement

              will be able to bid on released capacity. NO EXCEPTIONS.

              2) All bids are binding. Once bidding closes, both the Releasing
              Shipper and the winning bidder will be able to print from NrG
              Highway a Capacity Release Offer Report (CROR). The CROR will list
              all details of the Capacity Release: Releasing Shipper,
              Replacement Shipper; volumes, rate, recallability, etc.

              3) DUNS Numbers are mandatory for capacity release, which will be
              done via NrG. Please call Electronic Commerce Coordinator, at
              203-944-7020 if you have any questions regarding your DUNS number,
              including whether you currently have one listed with us from
              previous solicitations.
