                          RATE CALCULATION METHODOLOGY


INTRODUCTION AND GENERAL

         Gas transportation rates charged by Alberta Natural Gas Company Ltd
(ANG) to its shippers are based on a determination of conventional cost of
service including return on a fully depreciated rate base.  The costs included
are limited to those incurred in the operation of ANG's gas pipeline system
located in south east British Columbia plus (after October 31, 1993) the
amounts billed to ANG by Foothills Pipe Lines Limited under tariffs approved by
the National Energy Board.

         ANG fixes its rates in consultation with its shippers.  Such
consultations determine matters such as ANG's deemed capital structure,
appropriate rates for debt interest expense (if no debt actually is in place),
equity return rate, depreciation policy, etc.

         To ensure that rates reflect actual ANG costs, an adjustment to the
rates calculation is carried forward from the preceding period each time rates
are recalculated.  The adjustment corrects for the difference between revenue
requirements and actual revenue collections for the preceding period.  Firm
service rates are based on net costs after deduction of revenues collected from
interruptible shippers.

         Rates established from time to time are set out on the Statement of
Effective Rates and Charges, Sheet 20, contained in ANG's Gas Transportation
Service Documents, filed with the National Energy Board and made available to
all ANG shippers and prospective shippers.

2.4      (a)     If the gas tendered for transportation shall fail at any time
                 to conform to any of the specifications set forth in this
                 Section 2, then Company shall notify Shipper of such
                 deficiency and may, at its option, refuse to accept such gas
                 pending the remedying such failure to conform to quality
                 specifications.  If the deficiency in quality is not promptly
                 remedied, Company may accept such gas and may make changes
                 necessary to bring such gas into conformity with such quality
                 specifications and Company shall include all reasonable
                 expenses incurred by it in effecting such changes in Shipper's
                 monthly bill.

         (b)     Notwithstanding subsection 2.4(a) above, Company shall have

                 2.1 hereof.  Provided, however, that any such suspension shall
                 not relieve Shipper from any obligation to pay its demand
                 charge, or any other charge payable to Company.

2.5              Company shall establish reasonable methods and procedures,
including instrumentation, for making tests to determine whether gas tendered
by Shipper to Company for transportation or delivered by Company to Shipper
meet the specifications set forth in this Section 2.

that correction for deviations from Boyle's Law shall be determined from data
contained in the "American Gas Association Manual for the Determination of
Super Compressibility Factors for Natural Gas, AGA No. 8" or "Par Research
Project NX-19" as published by the American Gas Association in 1962, or any
subsequent revision thereof acceptable to Company and Shipper.

3.7              For the purposes of measurement the atmospheric pressure at
any Receipt Point or Delivery Point shall be fixed by agreement between Shipper
and Company and by a method that meets the requirements of the GIA.

3.8              The gas characteristics, including gross heating value,
relative density, and nitrogen and carbon dioxide content of the gas tendered
by Shipper to Company for transportation at the Receipt Point or delivered by
Company at the Delivery Point shall be determined, where applicable, by
recording equipment approved for this use under the provisions of the GIA.

                              MEASURING INSPECTION

4.1              The accuracy of Company's measuring equipment shall be
verified at monthly intervals or at such larger intervals as the Company and
the Shippers may agree.  Advance notice of the time and nature of each test
shall be given to allow shipper a reasonable amount of time to arrange for a
representative to observe the test and any adjustments resulting from such
tests.  If, after notice, Shipper fails to have a representative present, the
results of the test shall nevertheless be considered accurate until the next
test.

4.2              If, as a result of any such tests any of the measuring
equipment is found to be out of service or registering inaccurately in
comparison to Company's calibration equipment, it shall be adjusted at once to
read as accurately as possible.  If such equipment is out of service or
inaccurate such that it causes a measurement error or an energy basis of less
than one-half of one percent, a correction may be made at Company's option.  If
such measurement error is greater than or equal to one-half of one percent as
aforesaid, then the previous readings of such equipment shall be corrected to
zero error for a period agreed upon, or if not as agreed upon, for a period of
one-half (1/2) of the elapsed time since the last test.  The volume of gas
delivered during such period shall be determined by Company using one of the
following four (4) methods, which in the opinion of the Company will provide
the most accurate results:

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

         (b)     by correcting the error if ascertainable by calibration test
                 or mathematical calculation; or

         (c)     by estimating the quantity delivered based upon deliveries
                 under similar conditions during a period when the equipment
                 was registering accurately; or

         (d)     by calculation of the balance between Company's receipts and
                 deliveries over the period.

4.3              If Shipper requests a special test of accuracy of any
measuring equipment and upon testing the equipment the inaccuracy of the
equipment is found to be less than one (1) percent, Shipper shall bear the
expense of such special test.

4.4              Shipper or Shipper's agent shall have the right to inspect, at
Shipper's expense, Company furnished or installed measuring equipment and other
Company measurement or test data including, where applicable, charts at all
times during normal business hours, but the reading, calibration and adjustment
of such equipment and, where applicable, the changing of charts shall be done
only by Company or Company's agent.

4.5              The parties hereto shall exchange, upon request of either
party, copies of all measuring and testing data and information including,
where applicable, charts as soon as practicable for any such requests.

5.1              Shipper's share of Company Use Gas shall be provided by
Shipper in kind, or by Company pursuant to paragraph 5.3 of this Article V.
Shipper's share of Company Use Gas on any day shall be the total Company Use
Gas for the month in which such day falls divided by the days in such month,
multiplied by Shipper's volume delivered by Company on such day and by
Shipper's Haul Distance, and divided by the sum of the products of all
shippers' volumes delivered by Company on such day and such shippers' Haul
Distances.

5.2              Shipper shall have the right, exercisable by notice to Company
at least 60 days prior to the Service Availability Date to supply in kind its
share of Company Use Gas.  This election shall apply to each subsequent
Contract Year unless the Shipper provides the Company with notice to the
contrary at least 60 days prior to the start of any subsequent Contract Year.

5.3              If Shipper elects not to exercise its right to supply
Shipper's share of Company Use Gas, Company may, at its option, either:

         (a)     supply Shipper's share of Company Use Gas and bill Shipper for
                 the quantity supplied at the price set out in paragraph 5.4 of
                 this Article V, or

         (b)     take Shipper's share in kind from the volumes transported by
                 Company for Shipper.

5.4              In the event that Company provides Shipper's share of Company
Use Gas the price to be charged Shipper by Company for such gas volumes shall
be the price set out in Company's currently effective Statement of Effective
Rates and Charges.

6.1              On or before the twentieth (20th) day of a month, beginning
with the twentieth (20th) day of the month immediately following the month in
which the Service Availability Date occurs, Company shall render a bill to
Shipper for the prior month.  When information necessary for billing by Company
is in control of Shipper, Shipper shall furnish such information to Company on
or before the fifth (5th) day of the month in connection with services rendered
during the prior month.

6.2              Shipper shall make payment of such bill to Company on or
before the last day of such month.

6.3              If presentation of a bill by Company is delayed after the
twentieth (20th) day of the month, then the time for payment shall be extended
correspondingly, unless Shipper is responsible for such delay.

6.4      Interest on Unpaid Amounts

                 Except where presentation of the bill is delayed under
paragraph 6.3 or as provided under paragraph 6.5, Company shall have the right
to charge interest on the unpaid portion of any bill commencing with the date
payment was due and continuing until the date payment is actually made.  The
initial rate of interest to be charged by Company shall be the rate of interest
which is (2%) percent over and above the Prime Rate quoted by the Royal Bank of
Canada on the first day of the quarter during which such unpaid portion of the
bill becomes due.  The first day of the quarter during each year shall be
deemed to be the first day of January, April, July and October, as the case may
be.  The rate of interest in effect during a prior quarter, with respect

to any amounts owning in such prior quarter which remain outstanding in the
following quarter, shall be adjusted effective the first day of the following
quarter to the interest rate which is two (2%) percent over and above the Prime
Rate in effect on the first day of such following quarter.

6.5      Adjustment Where Bill Estimated

                 Information used for billing may be actual or estimated.  If
actual information necessary for billing is unavailable to Company sufficiently
in advance of the twentieth (20th) day of the month to permit the use of such
information in the preparation of a bill, Company shall use reasonably
estimated information.  In the month that actual information becomes available
respecting a previous month where estimated information was used, the bill for
the month in which the information became available shall be adjusted to
reflect the difference between the actual and estimated information.  Neither
Company nor Shipper shall be entitled to interest on any adjustment.

6.6      Adjustment of Underpayment, Overpayment or Error in Billing

         (a)     In the event that an error is discovered in any bill rendered
                 by Company to Shipper for transportation services on Company's
                 Facilities, the amount of such error shall be adjusted,
                 provided that claim therefore shall have been made within
                 twelve (12) months from the date such bill was rendered.  The
                 adjustment shall be made within thirty (30) days of such
                 timely claim.

         (b)     In the event that an overpayment has been made, Company shall
                 make reimbursement of such overpayment.  Shipper shall be
                 entitled to interest on the amount of such overpayment from
                 the time such overcharge was paid to the date of
                 reimbursement.  The initial rate of interest shall be
                 determined as set forth in paragraph 6.4 of this Article VI
                 and shall be revised with respect to any subsequent quarter
                 prior to adjustment of error, in the manner set forth for
                 revision of such initial rate in such paragraph 6.4

         (c)     In the event of an undercharge, Shipper shall pay the amount
                 of any such undercharge to Company but without interest.  Such
                 amount shall be payable on the same terms and conditions as
                 all amounts payable by Shipper to Company.

6.7              In the event Shipper disputes in good faith any part of a
monthly bill, Shipper shall nevertheless pay to Company the full amount of the
bill within the time such payment is due together with a statement of and
explanation respecting the amount so disputed.  Company shall segregate that
portion of the payment in dispute from its general funds by placing such
portion in a separate account to be held in trust by Company pending resolution
of the dispute.

6.8              In the event Shipper fails to pay the full amount of any bill
within (30) days after payment is due, Company, in addition to any other remedy
it may have, may suspend receipt and delivery of gas until full payment is
made.  Such suspension shall not relieve Shipper from any obligation to pay any
charge payable hereunder to Company.

                 If Shipper's failure to pay the full amount outstanding in
respect of any month bill shall continue after such suspension, Company may,
in addition to any other remedy Company may have, terminate Shipper's Service
Agreement effective on the date of the delivery of written notice by the
Company to Shipper of such termination.

         (c)     If Shipper elects not to exercise its right to supply
                 Shipper's Share of Company's Line Pack Requirements, Company
                 may purchase such quantity of line pack from Shipper, or if
                 Company can purchase line pack at a price lower than the price
                 quoted by Shipper, Company may purchase Shipper's share from

a point which is upstream of the Delivery Point, provided that Shipper will pay
to Company the same monthly demand charge which would have been otherwise
payable had such diversion not occurred.

at 4200 kPa, or, with Company's agreement, at such pressure as will enable the
gas to enter Company's Facilities, but in no event shall Shipper be required to
deliver the gas at a pressure greater than 5826 kPa.

10.2             Shipper recognizes that Company will be transporting the gas
in a commingled stream to the Delivery Point and that the pressure of the gas

                SERVICE PRIORITIES, INTERRUPTION AND CURTAILMENT

11.1             All firm service shippers who are receiving transportation
service shall have equal priorities of service.  In the event that Company's
pipeline capacity is constrained by the need to effect any repairs,
maintenance, replacement or upgrading or other work related to Company's
Facilities, or for any other reason such that all firm service volumes cannot
be delivered, Company shall first interrupt all deliveries under interruptible
service agreements and shall then act to maximize its total deliveries under
firm service agreements.  If curtailments continue to be required, Company
shall curtail all firm service deliveries pro rata with the Maximum Day
Delivery Quantity of each shipper.

11.2             If capacity remains in Company's Facilities after first 
meeting all firm service nominations, Company shall transport gas requested 
by shippers pursuant to paragraph 4 Make-Up Provision, of Service Schedule 
FS-1.  If additional capacity remains, Company shall transport gas under 
interruptible service agreements.  Interruptible volumes shall be transported 
on a priority ranking as described in Service Schedule IS-1.

11.3             Company may interrupt, curtail or reduce service for such
periods of times as it may reasonably require for the purpose of effecting any
repairs, maintenance, replacement or other upgrading, or other work related to
Company's Facilities.  Company shall give firm shippers at least three (3) days
notice of such interruptions or curtailments or, in the event of unforeseen
circumstances, such shorter notice as it is reasonably possible for Company to
give.  Company shall consult annually with shippers respecting the scheduling
of major maintenance programs.

11.4             Shipper and Company shall give each other as much notice as is
reasonably possible in the circumstances of unexpected temporary changes in the
rates of delivery or receipt of gas, pressures or any other operating
conditions, together with the expected duration and the reason for such
expected temporary changes.

11.5             Shipper acknowledges and agrees with Company that any
interruption or curtailment shall not suspend or relieve Shipper from the
obligation to pay any demand charge, surcharge, or any other amount payable to
Company, except as provided in paragraph 3.6 of Service Schedule FS-1.

                              DELIVERY OBLIGATION

12.1             Company's delivery obligation for any period where Shipper has
exercised its right as provided in paragraph 5.2 shall be to deliver to Shipper
at Shipper's Delivery Point, the volume of gas which has the aggregate energy
content of gas received from Shipper in such period at Shipper's Receipt Point,
less Shipper's share of Company Use Gas as determined under paragraph 5.1.
Company's delivery obligation for any period where Company has exercised its
option to supply Shipper's share of Company's requirements as provided for in
paragraph 5.3 (a), shall be to deliver to Shipper at Shipper's Delivery Point
the volume of gas which has the aggregate energy content of gas received from
Shipper in such period at Shipper's Receipt Point.

12.2             Gas delivered by Company to Shipper at Shipper's Delivery
Point shall have the heating value and the quality that results from the gas
having been transported and commingled with gas belonging to others in
Company's Facilities.

12.3             All deliveries of gas to Company at a Receipt Point shall be
made in uniform hourly quantities to the extent practicable.

                                 FORCE MAJEURE

13.1             As utilized herein, force majeure shall mean any act of God,
strikes, lockouts, or other industrial disturbances, acts of the Queen's
enemies, sabotage, wars, blockades, insurrections, riots, epidemics,
landslides, lightning, earthquakes, floods, storms, fires, washouts, arrests
and restraints of rulers and peoples, civil disturbances, explosions,
breakages, or accidents to machinery or pipelines, hydrate obstructions of
pipelines or appurtenances thereto, inability to obtain materials or equipment,
inability to obtain permits, orders, licenses, certificates or other
authorizations; orders of any court, board or governmental authority having
jurisdiction, any claim by any third party that any covenant or obligation of
such third party is suspended by reason of force majeure, including without
limiting the generality of the foregoing any such claim by any transporter of
gas to, from or for Company or Shipper; or any other cause, whether of the kind
therein enumerated or otherwise not within the control of the applicable party
or that shall be occasioned by the necessity of making repairs to or
reconditioning machinery, equipment or pipeline facilities not resulting from
the default or negligence of such party and which by the exercise of due
diligence such party is unable to prevent or overcome.

13.2             If either party fails to perform any obligations imposed by
this Agreement and such failure shall be caused or materially contributed to by
any occurrence of force majeure such failure shall be deemed not to be a breach
of the obligation of such party, but such party shall use reasonable diligence
to put itself in a position to carry out its obligations.  Provided, however,
that the settlement of strikes or lockouts shall be entirely within the
discretion of each party, and that the above requirement that any force majeure
shall be remedied with the exercise of due diligence shall not require the
settlement of strikes or lockouts by acceding to the demands of the opposing
party when such course is inadvisable in the discretion of the appropriate
party.

13.3             Notwithstanding any other provision herein, no cause 
affecting the performance of obligations by any party:

         (a)     shall relieve any party from its obligations to make payment,
                 except as provided in paragraph 3.6 of Service Schedule FS-1,
                 of amounts pursuant to Shipper's Service Agreement;

         (b)     shall relieve any party from any other obligation unless such
                 party shall give notice of such cause in writing to the other
                 party with reasonable promptness and like notice shall be
                 given upon termination of such cause, nor shall such cause
                 continue to relieve such party from such other obligation
                 after the expiration of a reasonable period of item within
                 which, by the use of due diligence, such party could have
                 remedied the situation.

13.4             Notwithstanding any other provision herein, Company and
Shipper agree that a lack of funds or other financial cause shall not under any
circumstances be an event of force majeure.

13.5             In the event that the provision of service is curtailed or
interrupted by reason of force majeure Company shall, during the continuance of
such force majeure, curtail or interrupt service in accordance with Article XI
hereof.

                 Company provided for in any Service Agreement);

         (b)     Company shall have no liability, nor obligation to indemnify
