required under  applicable law and (ii) the date on which Buyer's  restructuring
with Niagara Mohawk Power  Corporation for Buyer's Plant becomes  effective,  in
respect of which Buyer shall forthwith  deliver to Seller an irrevocable  notice
from Buyer to Seller. On and after the Effective Date, the Original Gas Purchase
Contract as amended hereby and as restated herein shall govern the  relationship
of Buyer and Seller.  Buyer and Seller agree that the rights and  obligations of
the  parties  prior to the  Effective  Date  have been and are  governed  by the
Original Gas  Purchase  Contract  prior to giving  effect to the  amendment  and
restatement of the Original Gas Purchase Contract embodied in this Contract, and
Buyer and Seller  expressly  reserve all rights  accrued  under the Original Gas
Purchase Contract prior to the Effective Date.

              6.1.b.  If the Effective  Date has not occurred by August 31, 1998
(as such  date  may be  extended,  but only by  mutual  agreement  of Buyer  and
Seller),  this Contract shall  terminate  without further action of either party
and be deemed void ab initio,  and the  Original  Gas  Purchase  Contract  shall
continue  to be in full force and effect in  accordance  with its terms  without
regard to this Contract.

6.2  This Contract shall continue in full force and effect until:


              6.2.a.  Fifteen (15) years after the date of  Commencement of Firm
Deliveries hereof ("primary term"); provided, however, that Buyer shall have the
right,  exercisable  by  notice  to  Seller  delivered  by the end of the  tenth
contract year hereunder,  to enter into a new gas purchase  contract in the form
attached as Exhibit E hereto (the "New  Contract")  for a term of four (4) years
(or five (5) years upon mutual  agreement of Buyer and Seller) (the "New Term"),
subject to the receipt of all  authorizations  of U.S. and  Canadian  Regulatory
Authorities necessary for the parties to perform their obligations under the New
Contract.  Notwithstanding  Buyer's  exercise of its right to enter into the New
Contract, Buyer shall have the right to terminate the New Contract, before or at
any time during the New Term upon  delivery of not less than twelve (12) month's
advance written notice to Seller.

              6.2.b.  Such  earlier  date as may be required to conform  with an

6.3 If at any time  following  the approval of this Contract by the AEUB and for
the life of this Contract, Seller has less than a Minimum Removal Permit, Seller
shall,  within  one year  from the first day of the  applicable  contract  year,
obtain a Minimum  Removal  Permit.  Failure to cure a  shortfall  in the Minimum
Removal  Permit  within  the one year  cure  period  provided  in the  preceding
sentence  shall  constitute  a  material  breach  by Seller  giving  rise to the
remedies set forth in Article 22 of this Contract.

6.4.a. Seller and Buyer agree to use their best efforts to obtain,  maintain and
extend  applicable  authorizations  of United  States  and  Canadian  Regulatory
Authorities to permit the full  performance of this Contract,  including but not
restricted  to (1) Section  2.4, (2) the removal from the Province of Alberta of
the full  quantities of gas contracted  for in this Contract in accordance  with
the terms  hereof,  and (3) the export from Canada and into the United States of
at least 15,000 Mcf of gas per day.

              6.4.b.  (i)  Seller  shall  be  responsible  for  carriage  of any
application to obtain or extend the Minimum Removal Permit, provided that Seller
and Buyer shall be co-applicants,  Seller shall use due diligence to ensure that
written communication from the AEUB is directed to both Buyer and Seller, Seller
shall  provide  Buyer with copies of all material  sent to the AEUB within three
(3) business days of such delivery,  and Seller shall inform Buyer of the status
of applications as developments  occur. Buyer shall use due diligence to provide
Seller  with  information  requested  by the  AEUB  which  Seller  does not have
available to it and which Buyer has available to it.

                                                                 Execution Copy


                  (ii)  Neither  Buyer nor  Seller  shall do any acts to change,
alter or vary the AEUB removal  permit,  or any extension or amendment  thereof,
except as provided  herein,  without the consent of the other,  irrespective  of
whether  the  removal  permit as issued  or  amended  is in the name of Buyer or
Seller alone.


          6.4.c.  (i) Buyer shall be responsible for carriage of any application
to obtain or extend the NEB export  license.  Buyer  shall  provide  Seller with
copies  of all  material  sent to or  received  from the NEB  within  three  (3)
business  days of  transmittal  or receipt,  as the case may be, and Buyer shall
inform Seller of the status of applications as developments  occur. Seller shall
use due diligence to provide Buyer with  information  requested by the NEB which
Buyer does not have available to it and which Seller has available to it.


                  (ii)  Neither  Buyer nor  Seller  shall do any acts to change,
alter or vary the NEB export  license,  or any  extension or amendment  thereof,
which would impair such NEB export license without the consent of the other.


ARTICLE 7. PRICE


7.1 Upon the  Commencement of Firm Deliveries and thereafter for the term hereof
as   provided   in  Article  6,  Buyer  shall  pay  to  Seller  (a)  a  Variable
Transportation Charge determined in accordance with Section 7.3, (b) a Commodity
Charge  determined  in  accordance  with  Sections  7.4 and  7.5,  and (c) a Gas
Inventory  Charge  determined  in  accordance  with Section 7.6. The "Price" per
month for gas service hereunder shall be the sum of the Variable  Transportation
Charge  multiplied by the total  quantity of gas delivered to TCPL  hereunder on
that  month,  the  Commodity  Charge  multiplied  by the total  quantity  of gas
delivered to TCPL hereunder in that month and the

                                       16

                                                                 Execution Copy


Gas Inventory  Charge.  For purposes of determining the Variable  Transportation
Charge,  "NOVA Charge" means the total charge in Canadian dollars paid per month
by Seller to NOVA for transportation capacity to Empress,  Alberta of a quantity
of gas equal to the Maximum Daily  Quantity for each day in such month,  subject
to normal monthly  adjustments by NOVA,  provided (i) that the ratio of Seller's
receipt  point  demand to Delivery  Point  demand shall not exceed 1:1; and (ii)
that such charge excludes specific facilities charges.

7.2. All charges  shall be expressed  in United  States  dollars for purposes of
determining the Price.  Any necessary  conversions  from either United States or
Canadian  currency  with  respect  to any  charges  for any month  shall be: (a)
calculated at the rate of exchange published in the "Canadian Gas Price Reporter
Table:  Monthly  Canadian and U.S. natural gas price summary" for such month; or
(b)  calculated  in the  manner  that  may be  prescribed  from  time to time by
Canadian Regulatory Authorities.

7.3. The Variable  Transportation  Charge for gas delivered to TCPL hereunder in
any month shall be the NOVA Charge per 103m3, calculated on the
basis of 100% load factor,  for such month,  payable  monthly in accordance with
Article 8.

7.4.a. The Commodity Charge per MMBtu for gas delivered in any month, payable
monthly  in  accordance  with  Article  8,  shall be the  amount  determined  in
accordance with the following formula:


                                 CC = ABP - VTC

                                       17

                                                                 Execution Copy


Where:


"CC" is the Commodity Charge;


"ABP" is the  Adjusted  Base  Price  for such  month  and  shall be equal to the
current month's "Avg.  Border (Empress) "Bid Week" Average Spot (One Month) Firm
(100% LF) price"  published in "The Canadian Gas Price Reporter Table:  Canadian
Natural  Gas  Supply  Prices"  converted  from  Cdn  $/GJ  to  Cdn  $/MMBtus  by
multiplying  by 1.054615  GJ/MMBtu and converted to US $/MMBtu by multiplying by
the current month  "Canada/U.S.  Exchange  Rate"  published in "The Canadian Gas
Price  Reporter  Table:  Monthly  Canadian and U.S.  natural gas price  summary"
rounded to the nearest cent;


"VTC" is the  Variable  Transportation  Charge for such month  converted to U.S.
dollars per GJ pursuant to Sections 7.2 and 7.11.


7.5 In the event that any specific  pricing index or publication  referred to in
this Section 7 is discontinued, the parties shall promptly agree on a substitute
pricing index or  publication  which is equivalent to the  discontinued  pricing
index or publication.  Such agreement shall be reflected in a mutual exchange of
letters deemed to amend this Contract for such limited purpose. In the event the
parties  are  unable to reach  agreement  as to a  substitute  pricing  index or
publication,  the matter shall be resolved by  arbitration  in  accordance  with
Article 20 hereof.

                                       18


                                                                 Execution Copy

7.6  7.6.a. The Gas  Inventory  Charge for any month  shall be equal to the NOVA
Charge less the product of (i) the Variable  Transportation Charge multiplied by
(ii) the total  quantity of gas  delivered  hereunder to TCPL during such month.
Seller shall invoice Buyer for the Gas Inventory Charge in Buyer's bill rendered
pursuant to Article 8 immediately following the completion of such month subject
to any  subsequent  monthly  adjustments  made by NOVA in  respect  of the  NOVA
Charge.


     7.6.b.  If Seller or NOVA fails to tender to TCPL,  wholly or in part,  the
Daily  Nomination  hereunder,  Buyer shall be relieved of its obligations to pay
the Gas Inventory  Charge to the extent of such failure,  calculated as follows:
the Gas Inventory Charge for any month in which deliveries are impaired shall be
reduced by an amount  equal to the  product of (i) the  Variable  Transportation
Charge and (ii) the difference between the total of the Daily Nomination on each
day of such month minus the total  quantity of gas  delivered  hereunder to TCPL
during such month.


     7.6.c.  The Gas Inventory  Charge for any month shall be further reduced by
an amount equal to the product of (i) the quantity of gas per 103m3 based on the
transportation  rights  elected to be used by Seller  pursuant to Section 2.4 of
Article 2 and (ii) the Variable Transportation Charge.


7.7 Upon Commencement of Firm Deliveries,  the minimum monthly bill shall be the
NOVA Charge.

                                       19

                                                                 Execution Copy

7.8 Any  conversion  from volume units to heating units required for the purpose
of this  Article 7 shall be based on the average  heating  value in the month of
delivery of the gas  received by TCPL at the  Delivery  Point for the account of
Buyer.


ARTICLE 8.  BILLINGS AND PAYMENTS


8.1  Subject to  Seller's  receipt of TCPL's  metering  statements  pursuant  to
Article 3 hereof, Seller shall render to Buyer on or before the tenth (10th) day
of each  month  after  the  first  sale of gas  hereunder  a  statement  for the
preceding  month in which the gas being  billed for was sold (the "Sale  Month")
showing the daily and total quantity of gas sold hereunder, the weighted average
Heating Value per cubic metre thereof, the applicable Price (determined pursuant
to Article 7), and the total amount payable to Seller therefore stated in United
States dollars (the "Sum").  Buyer agrees to deposit in Seller's  account at the
Bank of  Montreal,  Main Branch in Calgary,  Alberta,  Canada,  on or before the
twenty-fifth  (25th) day of each such month,  the Sum for the Sale Month. In the
event that Seller  fails to render a  statement  to Buyer on or before the tenth
(10th) day of a month,  the date by which Buyer must deposit the Sum in Seller's
account  shall be  extended  one day for each day  Seller's  statement  is late;
provided,  however,  that if Seller is unable to render a statement on or before
the tenth  (10th) day of a month,  Seller may at its option  render an estimated
statement to Buyer which statement  shall contain  Seller's best estimate of the
daily and total quantity of gas sold hereunder  during the preceding  month, the
weighted  average  Heating Value per cubic metre  thereof,  and the total amount
payable by Buyer therefore stated in United States dollars.  Buyer shall deposit
in Seller's  account the Sum for such  estimated  statement  within fifteen (15)
days of its receipt but no sooner than the 25th day of the month.  For any month
in which Seller renders an estimated statement to Buyer, Seller shall render the
final  statement for 

                                       20

                                                                 Execution Copy

such month with  Seller's  statement  for the next  succeeding  month.  Seller's
statement for such next  succeeding  month shall  reflect an adjustment  for any
difference  between the  estimated  statement  and the final  statement  for the
previous  month,  which  shall be added to or  deducted  from,  as  appropriate,
Seller's statement for such next succeeding month. If Buyer fails to deposit the
Sum or any portion  thereof,  in  Seller's  account  when same is due,  interest
thereon shall accrue at the annual rate of interest which is equal to the sum of
two percent (2%) plus the Prime Rate until the same is paid.

8.2.  If Buyer's  failure to pay  continues  for thirty  (30) days,  Seller,  in
addition to all other remedies, may thereafter suspend the sale of gas hereunder
and if such  default  continues  for thirty  (30)  additional  days,  Seller may
thereafter,  in addition to any other  rights  Seller may have,  terminate  this
Contract;  provided,  however,  in order for Seller to have the right to suspend
sales or  terminate  this  Contract,  Seller must first have  notified  Buyer in
writing  fifteen (15) days prior to exercising such right of its intent to do so
and give Buyer the right to pay the amount so due to Seller  within such fifteen
(15) day  period;  and  provided,  further,  that if Buyer in good  faith  shall
dispute the amount of any such bill or any part  thereof and shall pay to Seller
such  amounts as it  concedes to be correct  and at any time  thereafter  within
twenty  (20)  days of a  demand  made by  Seller  shall  furnish  or cause to be
furnished a good and sufficient surety bond satisfactory to Seller, guaranteeing
payment  to Seller of the  amount  ultimately  found due upon such bill  after a
final  determination which may be reached either by agreement or judgment of the
courts, as may be the case, then Seller shall not be entitled to suspend further
sales of gas because of such nonpayment  unless and until default be made in the
conditions of such bond.

                                       21


                                                                 Execution Copy


8.3.  Each party shall have the right to inspect  and examine at all  reasonable
times the records and charts of the other party  pertaining  to the purchase and
sale of gas hereunder. If any overcharge or undercharge in any amount whatsoever
shall  be  found  within  two (2)  years  of the  date of  billing  and the bill
therefore  has been paid,  Seller shall refund the amount of the  overcharge  or
Buyer shall pay the amount of the undercharge  within thirty (30) days after the
final determination thereof, with interest thereon for the period the overcharge
or undercharge was  outstanding  calculated at the annual rate of interest which
is equal to the sum of two percent  (2%) plus the Prime Rate.  This  Section 8.3
shall survive termination of this Contract.


ARTICLE 9. QUALITY


9.1 Seller agrees to sell and cause to be delivered and Buyer agrees to purchase
and cause to be received at the Delivery Point, gas which shall meet the quality
specifications  set forth in the TCPL tariff governing the transportation of the
gas sold  hereunder.  

9.2. If the gas offered for delivery  hereunder by Seller shall fail at any time
to conform to any of the  specifications  identified  in Section 9.1, then Buyer
shall notify Seller of such  deficiency  and thereupon  may, at Buyer's  option,
refuse to purchase such gas pending correction by Seller.  Upon Seller's failure
promptly to remedy any such  deficiency in quality,  Buyer may purchase such gas
and may make  changes  necessary  to bring  such gas into  conformity  with such
specifications,  and Seller shall  reimburse  Buyer for any  reasonable  expense
incurred by Buyer in effecting such changes.

                                       22

                                                                 Execution Copy


ARTICLE 10.  MEASUREMENT OF GAS


10.1 Seller and Buyer agree that the  measurement  of the gas to be delivered by
Seller and received by Buyer at the Delivery  Point shall be  determined  by the
measurement provisions set forth in the TCPL Tariff governing the transportation
of the gas sold hereunder.


ARTICLE 11.  POSSESSION AND TITLE

11.1 Possession of and title to gas sold by Seller to Buyer hereunder shall pass
from Seller to Buyer at the Delivery  Point.  Until the gas reaches the Delivery
Point,  Seller  shall  be  deemed  to be in  control  of and  have  title to and
possession of and be responsible for such gas, after which Buyer shall be deemed
to be in control of and possession of and have title to and be  responsible  for
such gas.


ARTICLE 12.  SELLER'S REPRESENTATIONS AND WARRANTIES


12.1 Seller represents and warrants that: (i) it has full right and authority to

and the right to sell the gas to be sold and  delivered  hereunder  and all such
gas is owned or  authorized to be sold by Seller and will be delivered by Seller
free from all Alberta  taxes,  liens,  charges and  adverse  claims  whatsoever,
including  liens to secure payment of any taxes.  Seller shall at all times have
the obligation to make  settlements  for all royalties and overriding  royalties
due and  payments to the mineral and royalty  owners  under the Leases and 

                                       23

                                                                 Execution Copy


other documents, as may appear of record or otherwise be binding upon Seller and
in accordance with the terms of the respective  Leases and other documents,  and
to make  settlements  with all other persons having any interest in the gas sold
hereunder. Seller agrees to indemnify Buyer and save it harmless from all suits,
actions,  debts,  accounts,  damages,  costs,  losses,  liabilities and expenses
arising from or out of claims of any other charges thereon,  which attach before
the title  passes to Buyer or which may be  levied  and  assessed  upon the sale
thereof to Buyer and are the responsibilities of Seller hereunder.

12.2. Seller represents that it is entitled to drill for, produce,  and sell gas
from Seller's Lands. Seller warrants and represents that Seller will, subject to
and in accordance  with the  provisions of this  Contract,  equip and tie-in its
wells and  construct or install its  facilities so as to be able to commence and
continue  delivery  of gas to Buyer in  accordance  with the  provision  of this
Contract.  Subject to Article 13, Seller covenants to diligently drill,  develop
and produce  Seller's  Reserves to the extent required by Section 14.4 such that
Deliverable Gas at the time of each Determination referred to in Article 14 will
be  sufficient  for Seller to supply the  Maximum  Daily  Quantity to Buyer from
Seller's  Reserves  for at least four (4)  contract  years  following  each such
Determination.  Upon  Commencement of Firm  Deliveries,  Seller shall deliver to
Buyer  sufficient  gas to meet  Seller's  obligations  under this  Contract from
Seller's Lands or from such other sources  available from time to time to Seller
provided that Seller has the right and necessary regulatory approvals to deliver
to Buyer from such other sources.


12.3.  12.3.a.  Seller  dedicates and commits  exclusively to the performance of
this  Contract  all of  Seller's  Reserves  and  represents  to Buyer  that such
Seller's Reserves will at all times (i) be sufficient in quantity and quality to
satisfy provincial and federal regulatory  authorities in respect of maintaining
a provincial  removal permit which satisfies the requirements of Section 6.3.a 
and a

                                       24

                                                                 Execution Copy


federal  export  license  for the full  term and  volumes  contemplated  in this
Contract;  (ii) contain Initial Recoverable  Reserves in an amount not less than
2,747.9  106m3 (97.01 Bcf) in accordance  with Section  14.3;  and (iii) contain
Deliverable Gas in an amount not less than the Minimum Deliverable Gas Amount in
accordance  with Section 14.4.  Seller's  Reserves shall not be named or used by
Seller or any third party to support any removal  permit or export license other
than the joint  removal  permit and the export  license to be  obtained by Buyer
based on Seller's Reserves to permit gas purchased  hereunder to be removed from
the Province of Alberta and delivered to Buyer.


     12.3.b.  Buyer is  hereby  authorized  by  Seller to  identify  and  commit
Seller's  Reserves in order to jointly obtain with Seller or extend a provincial
removal permit and to obtain on its own behalf or extend a NEB export license in
respect of the Maximum  Daily  Quantity  for the term of this  Contract.  Seller
agrees to cooperate  with Buyer and provide Buyer with such further  information
concerning Seller's Reserves as may be required for such purposes.


     12.3.c.  During the term of this Contract,  Seller shall not sell,  assign,
transfer or  otherwise  dispose of any  interest in  Seller's  Reserves  without
obtaining  Buyer's  prior  written  consent,  such  consent not be  unreasonably
withheld. Seller acknowledges that a reasonable condition to Buyer providing any
such consent would be the assumption  (by novation or other means  acceptable to
Buyer) by such third  party of that  portion  acquired  by such  third  party of
Seller's obligations to Buyer under this Contract.

     12.3.d.  Seller  represents  that no finding of producer  support under the
Alberta Natural Gas Marketing Act nor any joint working  interest owner approval
is or will be necessary  for Seller to fulfill its  obligations  under the terms
and conditions of this Contract.

facilities,  an equitable amount of such other gas or gas constituents  shall be
used in such facilities.


13.3 For the  purpose of causing  the gas to be  delivered  to meet the  quality
specifications  set forth in Article 9 hereof,  Seller may extract or permit the
extraction of non-hydrocarbon and hydrocarbon constituents as are required to be
extracted in order for the gas to meet such  specifications.

13.4.  Seller shall not be required to produce wells in excess of the lesser of:
(a)  their  respective  allowable  rates of flow as  fixed by law or  regulatory
bodies;  (b) their maximum  efficient rates of flow as determined by Seller;  or
(c) in instances of wells jointly operated with other parties,  the current rate
of  production   permitted  Seller  under  the  terms  of  applicable  operating
agreements.

13.5 13.5.a. Seller shall have the right on any day to make Third Party Sales in
an amount up to the Maximum  Daily  Quantity  provided (i) Seller shall have met
Buyer's Daily Nomination on such day and (ii) neither a Reserve Deficiency nor a
Deliverability  Deficiency  that must be cured  pursuant  to  Section  14.4 then
exists.  Seller may  accumulate its daily right to make Third Party Sales during
each calendar  month,  and amounts so accumulated  may be sold on any 

                                       27

                                                                 Execution Copy


day during such calendar  month and the following  calendar month in addition to
the daily limit for such day.  With  respect to any amount for which  Seller has
accumulated  its daily right to make Third  Party  Sales,  Seller  shall have no
further  right to make  Third  Party  Sales of such  amount  after the two month
period  applicable to such amount has elapsed.  Notwithstanding  the  foregoing,
Seller shall in no event make Third Party Sales  before  meeting  Buyer's  Daily
Nominations  on any day,  and in no event shall Seller make Third Party Sales in
an amount  exceeding  a quantity  equal to (a) the  product of (i) the number of
days in the relevant two-month period and (ii) the Maximum Daily Quantity,  less
(b) the sum of any Daily Nominations made by Buyer in such months.

     13.5.b.  In addition  to Third Party Sales as provided in Section  13.5.a.,
Seller shall have the right to make Excess Third Party Sales on any day provided
(i) Seller shall have met Buyer's Daily  Nomination on such day and (ii) neither
a Reserve Deficiency nor a Deliverability Deficiency that must be cured pursuant
to Section 14.4 then exists.


13.6 Seller may pool or unitize any of Seller's Lands with other properties and,
if any of Seller's  Lands are so pooled or unitized,  this  Contract  will cover
Seller's  interest  in the  unit  derived  therefrom  and the  gas  attributable
thereto;  provided,  however, that in the event that such pooling or unitization
is entered into voluntarily by Seller, it shall protect Buyer's rights hereunder
and prevent an appreciable reduction or postponement in the Article 2 quantities
of gas to be sold by Seller to Buyer.

Buyer and  Seller  agree  that,  from time to time as  appropriate,  they  shall
negotiate in good faith to agree upon  appropriate  action under or with respect
to this Contract to maintain or improve  

                                       28

                                                                 Execution Copy


alignment of deliverability of Seller's Reserves,  consistent with the efficient
administration  of Seller's lands and reserves and the full  performance of this
Contract,  and subject to the  receipt of all  necessary  regulatory  approvals,
which necessary  regulatory  approvals  shall not adversely  affect any existing
approval required under this Contract.

ARTICLE 14.  ASSURANCES OF GAS SUPPLY; SUBSTITUTE GAS SUPPLY

14.1 On or before  the date  upon  which  Seller  proposes  to make a  reduction
pursuant to Section  14.9 and on or before  each  September 1 during the term of
the Contract,  Seller shall  provide to Buyer,  at Seller's  expense,  a written
reserves and deliverability report ("Report").  Each Report shall be prepared by
McDaniels  Associates  ("McDaniels")  or another  independent  reserve  engineer
reasonably  acceptable  to Buyer.  Seller shall notify Buyer in writing not less
than three (3) months  prior to the  delivery  of a Report if Seller  intends to
employ an independent reserve engineer other than McDaniels and Buyer shall have
thirty  (30) days to accept or reject  said  independent  reserve  engineer.  In
addition,  Buyer may inform Seller that  McDaniels,  or an  independent  reserve
engineer  subsequently  selected, as the case may be, is no longer an acceptable
independent  reserve  engineer  with respect to the next due Report upon written
notice  given not later than the  February 1 of the year in which such Report is
to be  delivered.  If Seller  and Buyer are  unable to agree  upon a  substitute
independent  reserve engineer,  the selection of an independent reserve engineer
shall be  submitted to  arbitration  pursuant to Article 20. If Buyer and Seller
are  unable to agree  upon a  substitute  independent  reserve  engineer,  or if
arbitration has not determined a substitute  independent  reserve  engineer,  in
either case, by September 1 of any year, Seller shall  nevertheless  provide the
Report due on such  September 1, which  Report  shall have been  prepared by the
independent reserve engineer which prepared the prior year's Report.  Failure to
agree on an

                                       29

                                                                 Execution Copy


independent  reserve engineer,  by negotiation or arbitration,  shall not excuse
Seller's failure to provide a Report on or before September 1 of each year.

     Each  Report  shall  redetermine  and set  forth  the  Initial  Recoverable
Reserves as of the first day of the  contract  year  immediately  following  the
Report. Each Report shall also determine and set forth the Deliverable Gas as at
the date of such  Report  under this  Contract  for each  contract  year for the
remainder of the Contract  term.  Each Report shall also set forth Seller's best
estimate  of the  cost to  drill  and  develop  additional  lands  and  reserves
necessary to cure a Deliverability  Deficiency (as defined in Section 14.4) (the
"Tie-in Cost") together with, when  applicable,  the information  required under
Section 14.4 and Section 14.9.


14.2 Buyer shall,  within 45 days of receipt of a Report,  advise Seller whether
such Report is acceptable to Buyer and if it is acceptable to Buyer, such Report
shall become the  "Determination"  for purposes of this Article 14. In the event
that Buyer advises Seller that such Report is not  acceptable,  Seller and Buyer
shall endeavor to agree upon a mutually acceptable Initial Recoverable Reserves,
Deliverable Gas, estimate of the Tie-in Cost, and land removal determination. In
the event that  Seller and Buyer do so agree,  their  determination  shall be in
writing,  shall set forth the Initial  Recoverable  Reserves,  Deliverable  Gas,
estimate of 

                                       30

                                                                 Execution Copy

the  Tie-in   Cost,   and  land   removal   determination,   and  shall  be  the
"Determination"  for  purposes of this  Article 14. In the event that Seller and
Buyer  are  unable  to agree  upon a  mutually  acceptable  Initial  Recoverable
Reserves,  Deliverable  Gas,  estimate  of the  Tie-in  Cost,  and land  removal
determination, either party may, within 90 days of delivery of Report, refer the
matter to  arbitration  pursuant  to Article 20 hereof.  An Initial  Recoverable
Reserves,  Deliverable  Gas,  estimate  of the  Tie-in  Cost,  and land  removal
determination  by arbitration  shall be in writing,  shall set forth the Initial
Recoverable  Reserves,  Deliverable  Gas,  estimate of the Tie-in Cost, and land
removal  determination  and shall be the  "Determination"  for  purposes of this
Article 14.

14.3 If a Determination  states that the Initial  Recoverable  Reserves are less
than 2,747.9 106m3 (97.01 Bcf), as adjusted to reflect on a proportionate basis,
any  decrease in the Maximum  Daily  Quantity  under the  Contract (a  "Reserves
Deficiency"),  then,  within twelve (12) months of the first day of the contract
year  immediately  following the Report upon which the  Determination  is based,
Seller shall dedicate  additional  lands and reserves to this Contract as needed
to cure the Reserves Deficiency.

14.4.  14.4.a.  If any  Determination  indicates that Deliverable Gas during the
first full five (5) contract years of 12 months each detailed in the Report upon
which the Determination is based is less than the Minimum Deliverable Gas Amount
(a  "Deliverability  Deficiency"),  then, within twelve (12) months of the first
day of the contract year immediately  following such Report, Seller shall either
(i)  increase the  deliverability  from  Seller's  Reserves  and, if  necessary,
dedicate  additional lands and reserves to this Contract,  as needed to cure the
Deliverability  Deficiency or (ii) provide a binding written  certification that
it reasonably  believes  that it can obtain gas from other  sources  ("Alternate
Sources") to meet its obligations  under this Contract and that it has the right
and necessary  regulatory  approvals to deliver such gas to Buyer (an "Alternate
Source Notice").

     14.4.b.  The Alternate Source Notice shall provide in reasonable detail the
facts  underlying  such  Notice and shall  identify  the extent to which  Seller
intends to rely on  Alternate  

                                       31

                                                                 Execution Copy

Sources. Seller shall not be entitled to seek excuse from its obligation to cure
a Deliverability  Deficiency as otherwise  permitted pursuant to Section 14.4.c.
for any period for which an Alternate  Source Notice is given.  All of the terms
and conditions of this Contract (including, without limitation, Seller's duty to
supply the Maximum Daily  Quantity and the pricing  terms with respect  thereto)
shall continue  unaffected by the Alternate  Source Notice.  Seller shall not be
entitled to deliver an Alternate Source Notice for any Deliverability Deficiency
relating to volumes attributable to Excess Third Party Sales. If for any reason,
Seller  is  unable  to meet at any  time  Buyer's  nomination  for gas up to the
Maximum  Daily  Quantity and Seller has provided an Alternate  Source Notice for
such period and Buyer is unable to use NOVA  transportation  otherwise available
to it under Section15.3 through no fault of its own, thenSeller shall thereafter
not be entitled to rely on the Alternate Source Notice in lieu of increasing the
deliverability  from  Seller's  Reserves,  but shall  thereupon  immediately  be
obligated  to cure the  Deliverability  Deficiency  in  accordance  with Section
14.4.a.(i) and Section 14.11.

     14.4.c.   Seller   shall  be  excused  from  its   obligation   to  cure  a
Deliverability  Deficiency pursuant to this Section 14.4, but only to the extent
that the  Deliverability  Deficiency  is not the  result of Excess  Third  Party
Sales, if:


     (a) The  Determination  provides Buyer with at least four (4) years advance
notice that  beginning with the fifth (5th) contract year following such current
Determination,  that  deliverability from Seller's Reserves will be insufficient
for Seller to meet its Maximum  Daily  Quantity  delivery  obligations  to Buyer
hereunder; and

                                       32

                                                                 Execution Copy

     (b) The  Determination  demonstrates  that for a period of at least  twelve
(12) consecutive months the weighted average price of gas under this Contract is
not  greater  than or equal to the price (the  "Sufficient  Acquisition  Price")
which would be necessary in order that  additional  gas supplies can be acquired
and produced to cure the Deliverability Deficiency; and 

     (c)  Buyer  does not  agree  within  six (6)  months  of the  Determination
referred to in  subsection  (b) to increase the Price under the Contract for the
Deliverability Deficiency to the Sufficient Acquisition Price effective from and
after the first month of the Deliverability Deficiency.


     The  Sufficient  Acquisition  Price shall,  until a contrary  Determination
pursuant  to  Section  14.4.b,  be deemed to be equal to the  Price  under  this
Contract.  In the event that Seller  intends to claim that the weighted  average
price of gas under this Contract is not greater than or equal to the  Sufficient
Acquisition  Price,  Seller shall instruct its independent  reserve  engineer to
include  as part of the  Report  which  Seller  proposes  to be the basis of the
Determination  referred to in Section 14.4.b a full and true  accounting  which:
(i)  identifies  the lands and reserves  which are  controlled  by or could with
reasonable diligence become controlled by Seller and used to supply the Contract
(the  "Available  Lands");  and (ii) and provides  Seller's  least cost estimate
(exclusive  of any return on monies  invested)  to drill,  develop,  process and
produce  from  each of the  Available  Lands  in a  manner  which  would  cure a
projected  Deliverability  Deficiency  in  whole  or in part  ("Net  Development
Costs"). For the purposes of estimating Net Development Costs, Seller's estimate
of the cost to drill  and  develop  the  Available  Lands  included  in such Net
Development  Costs for each of the Available Lands shall be reduced by 25%. Upon
receipt  of this  

                                       33

                                                                 Execution Copy

accounting and as part of such Report, Buyer and its agents shall be entitled to
attend at the offices of Seller and examine all title documents  relating to the
Available  Lands,  historical  information  and any other data used by Seller to
establish  its  Net  Development  Costs  including  the  audited  and  unaudited
accounting and record books of Seller, it being understood that Buyer shall keep
such information as is requested by Seller  confidential  except as required for
the purposes of this Contract.  Following Buyer's audit,  Buyer and Seller shall
use reasonable efforts to agree to a Sufficient  Acquisition Price failing which
the matter shall be determined  pursuant to arbitration  invoked with respect to
the Report in accordance  with Section 14.2. The  Arbitrator  shall consider and
determine the Sufficient  Acquisition Price based on the costs, exclusive of any
return on monies invested, of Seller developing the Available Lands to satisfy a
Deliverability Deficiency, together with any evidence adduced by the parties and
relevant to the determination.


14.5 In the event that Seller  cures a Reserve  Deficiency  or a  Deliverability
Deficiency  (each a "Deficiency")  for any given year prior to the expiration of
the  respective  cure periods  provided in Sections 14.3 and 14.4 (each, a "Cure
Period"),  Seller shall provide Buyer immediate  written notice  thereof,  to be
confirmed  within 60 days by an additional  Determination.  Once the Cure Period
for any contract year for which the  Determination  projects a Deficiency begins
to run,  the length of such Cure Period  shall not be altered by any  subsequent
Determination.

14.6 In each contract year that Seller issues a Report,  Buyer shall be entitled
to elect by written notice to Seller,  to be made within forty-five (45) days of
the receipt by Buyer of a Report in such contract  year, to review the contracts
and other documents and technical  information that are relevant to such Report.
Upon receiving such notice, and subject to Seller's reasonable needs to 

                                       34

                                                                 Execution Copy

maintain the confidentiality of any information,  Seller shall permit Buyer, its
agents and advisors to conduct such review,  provided  that such review shall be
completed  within  forty-five  (45)  days of the date on which  Seller  has made
available such relevant contracts and documents.


14.7 14.7.a In the event that the Maximum  Daily  Quantity is reduced under this
Contract,  Buyer may arrange a substitute  supply of gas or other fuel  supplies
equal to all or part of the  portion  of the  Maximum  Daily  Quantity  which is
reduced.

     14.7.b.  Buyer and  Seller  shall  use their  best  efforts  to secure  all
necessary  regulatory  approvals to  implement  delivery of any  substitute  gas
supply by any  third-party  supplier or suppliers in the event the Maximum Daily
Quantity is reduced for  whatever  reason  pursuant  to this  Contract  with the
understanding  that any  provincial  removal  permit held by Seller and/or Buyer
shall be sought  to be  utilized  (by  transfer,  assignment  or  otherwise)  as
authorization of the removal and export by any third party supplier or suppliers
of any substitute gas supplies. Buyer and Seller agree to use their best efforts
to assist in accomplishing such transfer or assignment.

     14.7.c.  Upon  notice by Buyer to Seller  that  Buyer  has  arranged  for a
substitute gas supply,  Seller shall assign or otherwise-make  available to each
third party supplier a corresponding quantity of firm capacity on the facilities
of NOVA or other  intraprovincial  pipeline and, to the extent permitted by NOVA
or such other intraprovincial pipeline,  Seller's rights under its contract with
NOVA or such other intraprovincial  pipeline to the extent of the substitute gas
supplies to be supplied by each third-party supplier.

                                       35

                                                                 Execution Copy

14.8 In the event that the Maximum  Daily  Quantity  is reduced  pursuant to any
provision of this Contract and Buyer obtains a substitute gas supply pursuant to
Section 14.7 or other fuel supplies to operate Buyer's Plant,  and provided that
Seller's  failure  to  cure  the  Deficiency  is  not  excused  pursuant  to the
provisions of Section 14.4,  Seller shall  indemnify  Buyer for: (i) any and all
costs and expenses  reasonably  incurred by Buyer in  arranging,  obtaining  and
using  the  substitute  supply  of gas or other  fuel to the  extent  that  such
costs-and  expenses  exceed  those which  would have been  incurred by Buyer had
Seller delivered a quantity of gas equivalent to the substitute gas supply;  and
(ii) any  demand  charges  incurred  by  Buyer  pursuant  to its  transportation
contracts  with  TCPL  and  United  States  Transporter(s)  to the  extent  that
transportation under such contracts is not utilized by Buyer; provided, however,
that Seller's liability pursuant to this Section 14.8 shall not exceed an amount
equal to the  product  of the  amount  of the  reduction  in the  Maximum  Daily
Quantity and the sum of the demand charges per 103m3 or other  applicable  units
of measurement  incurred by Buyer pursuant to its transportation  contracts with
TCPL and United States Transporter(s).


14.9  14.9.a.  Seller and Buyer agree that not more  frequently  than once every
contract year, at such time as (i) Seller has a Minimum  Removal Permit and (ii)
Buyer  has an NEB  export  license  for the sum of 3,681  106m3  (130 Bcf) as at
November  1, 1992,  less the  amount of gas which  Seller is  permitted  to have
produced  from  Seller's  Lands as of the date of such removal  pursuant to this
Contract  (i.e.,  Buyer's  Daily  Nomination  plus Third Party  Sales  permitted
pursuant to Section 13.5),  and such NEB export license  authorizes the sale and
export from Canada of 424.9 103m3 (15,000 Mcf) per day for the unexpired term of
this  Contract,  then  Seller may remove from  Seller's  Lands as  described  in
Exhibit  A  any  lands  not   required  to  support  any   Canadian

                                       36

                                                                 Execution Copy

regulatory  authorizations  or approvals  required for the  performance  of this
Contract,  including,  but not limited  to, the NEB export  license and the AEUB
removal permit;  provided,  however,  that there shall have been a Determination
pursuant to Section  14.2 setting  forth the  information  required  pursuant to
Section 14.9.b (in addition to any other information  required to be included in
a Determination);  and provided, further, that the conditions of Sections 14.9.c
and 14.9.d have been satisfied.


     14.9.b.  If Seller  proposes  to remove  from  Seller's  Lands any lands as
described in Section 14.9.a,  there must first have been a Determination  which,
in addition to any other information required to be included in a Determination,
(i) identifies the lands and reserves proposed to be removed pursuant to Section
14.9.a and the lands and  reserves to remain  dedicated to this  Contract,  (ii)
establishes that  deliverability  from the remaining Seller's Reserves,  tied-in
and  producing  or in  respect  of which a letter of credit or letters of credit
have been  posted  for the  Tie-in  Cost are  sufficient  for Seller to meet its
Maximum Daily Quantity delivery obligations to Buyer hereunder for the then next
five (5) full contract years of at least twelve (12) months;  (iii)  establishes
that not less than 67% of the Seller's  Reserves after the proposed  removal are
proven  reserves  and  the  remainder  are  probable   reserves  using  NEB/AEUB
standards;  and (iv)  demonstrates  that Seller's  Tie-in Cost for the remaining
Seller's Reserves is not increased by the proposed removal.


     14.9.c.  No  removal  of  lands  pursuant  to this  Section  14.9  shall be
permitted  until (i) any  letter(s) of credit  required in  connection  with the
applicable  Determination shall have been posted, (ii) all regulatory  approvals
necessary for the removal of the proposed  lands from this 

                                       37

                                                                 Execution Copy

Contract  and from any existing  permit  required  for the  performance  of this
Contract,  including,  but not limited  to, the NEB export  license and the AEUB
removal  permit,  shall  have  been  received,  and  such  necessary  regulatory
approvals  shall not  adversely  affect any  existing  permit  required  for the
performance  of this  Contract,  including,  but not  limited to, the NEB export
license and the AEUB removal  permit and (iii) the Cure Gas Amount,  if any, has
been satisfied in accordance with Section 22.3.


     14.9.d.  Seller may not remove  tied-in  and  producing  Seller's  Reserves
pursuant to this Section 14.9 unless the remaining  Seller's  Reserves,  tied-in
and producing, are sufficient for Seller to maintain the Minimum Removal Permit.


     Buyer agrees to do such acts as are necessary to evidence  Seller's removal
of Lands completed in accordance with this Section 14.9.


14.10.  In the event that,  at any time,  Buyer and Seller agree to remove lands
from  Seller's  Lands  and  substitute   additional  different  lands  ("Reserve
Substitution"),  the  parties  shall use  reasonable  efforts to effect  Reserve
Substitution in a manner which provides Buyer with sufficient  security that the
Maximum Daily  Quantity will be met for the remaining  term of the Contract.  In
order to allow Buyer to assess a proposed  substitution of reserves Seller shall
provide Buyer with full information as may be requested by Buyer on the reserves
to be added as a result of the Reserve  Substitution.  Buyer shall  evaluate and
determine whether the Reserve Substitution  provides it with sufficient security
of supply.  In the event that Buyer and Seller  cannot  agree as to the  Reserve
Substitution  the matter  shall be  determined  by  arbitration  on the basis of
providing  Seller with the ability to produce up to the Maximum  Daily  Quantity
from the Seller's  Lands and 

                                       38

                                                                 Execution Copy

provide Buyer with  assurance that the Maximum Daily Quantity shall be available
for the  remaining  term of the  Contract  and on the basis  that only  lands of
equivalent  value will be  substituted  and,  further,  that  seller's  Reserves
following  any such Reserve  substitution  will meet the  conditions of Sections
14.9.b.(ii)-(iv)  (in each case,  applying such  conditions to the  substitution
rather than the removal of lands).  Seller may not replace tied-in and producing
Seller's  Reserves  pursuant to this  Section  14.10 unless  Seller's  Reserves,
tied-in and producing,  following such Reserve  Substitution,  are sufficient to
maintain the Minimum Removal Permit. Whether by agreement or by arbitration, the
Reserve  Substitution  shall not take  effect  until  both the AEUB and NEB have
demonstrated  to the  satisfaction  of Buyer  that a removal  permit  and export
license as required  under this  Contract  shall remain in full force and effect
notwithstanding the Reserve Substitution.


     Buyer  agrees  to do such  acts as are  necessary  to  evidence  a  Reserve
Substitution completed in accordance with this Section 14.10.


14.11. 14.11.a. If a Report indicates a Deliverability Deficiency and Seller has
not  provided an Alternate  Source  Notice  continuing  in effect for the period
covered  by the  Report  or is not  excused  from  its  obligation  to cure  the
Deliverability Deficiency pursuant to Section 14.4, Seller shall supply to Buyer
an irrevocable letter of credit, with a term of not less than one calendar year,
substantially in the form attached hereto as Exhibit D or otherwise satisfactory
to Buyer.  The letter of credit shall be transferable to the Collateral Agent or
other agent of the bondholders  under Buyer's Trust Indenture dated as of May 1,
1994,  as amended from time to time.  Buyer and Seller shall  promptly  take the
necessary and appropriate actions to transfer to such agent any letter of

                                      39

                                                                 Execution Copy

credit  outstanding on the Effective Date which does not on its face provide for
transfer  to such  agent.  The letter of credit  shall be issued by a  financial
institution  whose long-term  unsecured debt securities are rated A or better by
Standard and Poor's  Corporation or A or better by Dominion Bond Rating Service.
Each letter of credit shall be in the amount of the Tie-in Cost (as set forth in
the applicable  Report)  estimated by the independent  reserve  engineer for the
additional  lands and reserves  necessary to cure the applicable  Deliverability
Deficiency;  provided,  however,  that if Buyer does not accept such Report, the
amount of the  letter of credit  shall be  adjusted  to equal the  amount of the
Tie-in  Costs  for the  additional  lands  and  reserves  necessary  to cure the
Deliverability  Deficiency as set forth in the Determination,  which increase or
decrease  in the amount of the  letter of credit  shall be  effected  within ten
business days of such Determination,  unless Seller is not obligated to cure the
Deliverability  Deficiency pursuant to Section 14.4 with respect to the adjusted
Tie-in Cost.

     Seller shall supply any required  letter of credit  within the later of (i)
forty-five  (45) days of delivery to Buyer of a Report and (ii) five (5) days of
delivery to Seller of Buyer's response to such Report,  unless Seller shall have
sooner  cured  the  applicable  Deliverability  Deficiency  as  evidenced  by  a
Determination  in  accordance  with  Section  14.5.  Seller  agrees that (i) the
posting  of a letter of credit by the  Seller  in  respect  of a  Deliverability
Deficiency  identified  in a Report  which is  accepted  by Buyer,  and (ii) the

Determination  in  respect of the Tie-in  Cost  estimated  by Seller in a Report
which  was not so  accepted  by Buyer  shall in each  case,  but not  otherwise,
constitute  Seller's  conclusive   acknowledgment  that,  with  respect  to  the
Deliverability  Deficiency to which

indemnify itself to the extent of the costs, expenses and charges recoverable by
Buyer  pursuant to Section  14.8  ("Costs of Cover") if Seller has not cured the
Deliverability  Deficiency,  as evidenced by a Determination  in accordance with
Section 14.5, required to be cured by the expiration of the Cure Period for such
Deliverability  Deficiency.  Buyer shall  promptly  return to Seller any amounts
drawn on said letter of credit in excess of the Costs of Cover.

     14.1l.c.  Not less than  thirty (30) days prior to the  expiration  of such
letter of credit,  Seller  shall  provide  Buyer with  written  evidence  of the
renewal  of such  letter of  credit.  If Seller  does not renew  such  letter of
credit,  or if Seller fails to provide evidence of the renewal of such letter of
credit by the time required pursuant to the preceding  sentence,  and Seller has
not previously  cured the relevant  Deliverability  Deficiency as evidenced by a
Determination  in accordance with Section 14.5,  Buyer shall be entitled to draw
the full amount of such letter of credit  prior to its  expiration  and to apply
the  proceeds  of such a drawing  to its Costs of Cover.  Buyer  shall  promptly

Costs of Cover.

     14.1l.d. Upon curing, in whole or in part, a Deliverability  Deficiency, as
evidenced by a  Determination  in  accordance  with Section  14.5, in respect of
which a letter of credit has been posted,  Seller  shall be  entitled,  upon not
less than ten business  days' notice in writing to Buyer,  to have the amount of
the letter of credit  reduced to the extent of the value of the cure so effected
(if 

                                       41

                                                                 Execution Copy

such cure is partial  only) and to  withdraw  the  letter of credit,  if the
relevant Deliverability Deficiency has been completely cured.

14.12.  Seller shall provide to Buyer monthly the  information  required by AEUB
Form  S-1,  or any  successor  form,  for the  preceding  month  (the  "Form S-1
Information")  at the same time as Seller is required to provide  such AEUB Form
S-1 to the AEUB.  If for any reason the AEUB ceases to require  Seller to submit
to the AEUB Form S-1 or any successor form, Seller shall  nevertheless  continue
to provide to Buyer the Form S-1  Information by the fifteenth day of each month
for the  preceding  month.  If Seller does not  provide  Buyer with the Form S-1
Information when required,  Buyer shall be entitled to take whatever actions are
necessary  to obtain such Form S-1  Information,  including  examining  seller's
original  records upon which such Form S-1 Information is based if such Form S-1
Information  is not publicly  available from the AEUB in a timely  fashion,  and
Seller shall  reimburse  Buyer for Buyer's costs and expenses in obtaining  such
Form S-1 Information.

request,  a written estimate of the number of hours which Buyer anticipates that
the Plant will be dispatched on-line for the next following contract year. Buyer

act,  omission or  circumstances  occasioned by or in  consequence  of any event
constituting force majeure and the obligations of Seller and Buyer then existing
hereunder  shall be excused during the period thereof to the extent  affected by
such event of force  majeure.  The term  "force  majeure"  shall mean any cause,
whether  of the kind  enumerated  below or  otherwise,  and  whether  caused  or
occasioned  by or  happening  on  account of the act or  omission  of one of the
parties hereto which affects obligations hereunder not within the control of the
party  claiming  excuse and which by the exercise of due diligence such party is
unable  to  prevent  or  overcome,  including  but not  limited  to acts of God,
strikes, lockouts, acts of the public enemy, criminal acts of trespassers, wars,

                                       44

receive  gas for  Buyer's  account,  unscheduled  outages  which  result  in the
temporary inability of Buyer's Plant to utilize any portion of the Maximum Daily

been resisted in good faith by all  reasonable  legal means. A failure to settle
or  prevent  any  strike or other  controversy  with  employees  or with  anyone
purporting  or seeking to represent  employees  shall not be  considered to be a
matter within the control of the party claiming  excuse.  Under no circumstances
will lack of finances be construed  to  constitute  force  majeure.  

16.2. Such causes or contingencies affecting the performance of this contract by
either  party,  however,  shall not relieve it of  liability in the event of its
concurring  negligence  or in the event of its failure to use due  diligence  to
remedy the  situation  and remove the cause in an  adequate  manner and with all
reasonable dispatch, nor shall causes or contingencies affecting the performance
of this Contract  relieve either party from its  obligations to make payments of
amounts then due hereunder nor shall such causes or contingencies relieve either
party of liability  unless such party shall give notice and full  particulars of
the same in writing or by telex to the other party as soon as possible after the
occurrence relied on. 


16.3.  In the event,  as a result of force  majeure,  NOVA is  rendered  unable,
wholly or in part,  to deliver to TCPL for Buyer's  account  the  Maximum  Daily
Quantity provided for herein on any day,

                                       45

                                                                 Execution Copy


then Seller shall use  reasonable  efforts to meet the Daily  Nomination  at the
Delivery Point; provided, however, that Seller shall not be obligated to curtail
firm customers in order to meet its reasonable efforts obligation.

16.4.  Seller's  obligation  to sell and Buyer's right to purchase gas hereunder
shall be suspended during the  effectiveness  or any  governmental  action which
results  in the  interruption  of  deliveries  or  which  prevents,  totally  or
partially,  the exportation of gas from Canada,  the importation of gas into the
United  States by Buyer,  or  transportation  of gas by TCPL and  United  States
Transporter  for  Buyer;   provided,   however,   that  where  the  exportation,
importation,   use  or  transportation  is  only  partially   prevented  by  the
governmental action, Seller's and Buyer's obligations and rights hereunder shall
be suspended only to the extent prevented by such governmental action.

itself of its  obligations  under  this  Contract,  assign any of its rights and
obligations  hereunder to a corporation  with which it is affiliated at the time
of such assignment.

Otherwise no assignment  of this  Contract or any of its rights and  obligations
hereunder  shall be made by Seller  without the  written  consent of Buyer first
obtained which consent shall not be unreasonably  withheld.  Buyer may,  without

rights and obligations hereunder to a corporation with which it is affiliated at
the time of such assignment.  Otherwise no assignment of this Contract or any of
its rights or obligations  hereunder  shall be made by Buyer without the written
consent  of Seller  first  obtained  which  consent  shall  not be  unreasonably
withheld.  It is agreed,  however,  that the provisions of this Article 18 shall
not in any way prevent either party to this Contract from pledging or mortgaging
its rights  hereunder  as  security  for its  indebtedness.  In the event that a
person(s) with a security  interest in this Contract succeeds to the rights of a
party by foreclosure  or otherwise,  the other party shall accord such successor

Maximum Daily Quantity and the effective date of such reduction, such date to be
no earlier than the first (1st) day after the  expiration  of the Cure Period or
the thirtieth  (30th) day after the date of Buyer's notice,  whichever is later.
Upon Buyer's  exercise of its right under this Section 22.2.b,  Buyer shall have
no further remedies for the material breach which gave rise to such reduction in
the Maximum Daily Quantity, unless such material breach continues after the date
of the notice of the reduction of the Maximum Daily Quantity pursuant hereto.

     22.2.c.  Seller  shall not make any Third  Party  Sales  without  the prior
written  consent  of Buyer,  unless  this  Contract  provides  for a cure of the
material  breach and Seller has cured such breach in the manner required by this
Contract.

     22.2.d. Buyer may unilaterally take such action before any United States or
Canadian  Regulatory  Authority as Buyer shall deem  necessary or appropriate to
secure the full  performance  of this  Contract or to change,  alter or vary any
application, permit or license issued in connection with the gas to be delivered
under this Contract;  provided,  however,  that Seller does not hereby waive any
right to contest such action.

                                                                 Execution Copy


     22.2.e.  Seller shall not remove any portion of Seller's  Lands pursuant to
Section 14.9,  unless this Contract  provides for a cure of the material  breach
and Seller has cured such breach in the manner required by this Contract.


22.3 Buyer shall provide  Seller with fifteen (15) days advance  written  notice
prior to its  exercise of any of the  aforementioned  remedies  upon a Letter of
Credit Default and, upon Seller's delivery of a letter of credit which satisfies
the  requirements of Section 14.11 of this Contract within the said fifteen (15)
days,  such  Letter of Credit  Default  shall be deemed to be cured.

22.4.  The events  identified  in Section 22.2 as material  breaches are not the
exclusive  events which may  constitute a material  breach under this  Contract.
Upon the occurrence of a material  breach not identified in section 22.2 or upon
the occurrence of any other breach of this Contract,  and except as is otherwise
provided in this contract the non-breaching  party shall be entitled to exercise
all rights and remedies it may have at law or in equity and no single or partial
exercise of any right or remedy shall preclude any other or further  exercise of
any right or remedy at law or in equity. The respective liabilities of Buyer and
Seller hereunder for breach of any covenants,  representations or warranties and
the  respective  obligations  of Buyer and  Seller  under any  indemnity  herein
contained,  including any payments  required pursuant to Section 8.3 and Section
22.7,  shall survive  termination of this Agreement,  except as otherwise herein
expressly  provided.  


22.5. A party may withhold  payments due the other party under this  Contract to
offset damages,  costs and expenses reasonably incurred by the withholding party
as a result of a material breach of this Contract by such other party.

22.6. Any party which is found pursuant to a final judicial  determination to be
in breach of its  obligations  under this Contract  shall be liable to the other
party for all costs and expenses, including reasonable attorneys fees in respect
of such breach,  incurred by the  non-breaching  party in  enforcing  its rights
under this Contract.

22.7.  No  failure  or  delay on the part of a party  in  exercising  any  right
hereunder and no course of dealing between the parties which does not constitute
an agreement in writing  between the parties shall operate as a waiver  thereof.
No waiver by a party of any  breach or  default  of the other  party  under this
Contract  shall  operate  as a waiver of a future  default  whether of a like or
different character.
