               disqualified  from  relying  on  paragraph   1.1(d)(viii)  solely

          iv.  an  underwriter  or member of a banking  or  selling  group  that

          satisfied that the Market Price of securities as determined herein was
          affected  by an  anticipated  or actual  Take-over  Bid or by improper
          manipulation,  the  Board of  Directors  may,  acting  in good  faith,
          determine the Market Price of  securities,  such  determination  to be
          based on a finding as to the price at which a holder of  securities of
          that class could reasonably have expected to dispose of his securities
          immediately  prior to the relevant date  excluding any change in price
          reasonably  attributable to the anticipated or actual Take-over Bid or
          to the improper manipulation;

               (1)  a rights certificate ("Rights Certificate") representing the
                    number of Rights held by such holder at the Separation  Time
                    and having such markers of identification or designation and
                    such legends,  summaries or endorsements  printed thereon as
                    the  Corporation  may  deem   appropriate  and  as  are  not
                    inconsistent  with the provisions of this  Agreement,  or as
                    may be required to comply with any law, rule,  regulation or
                    judicial  or  administrative  order  or  with  any  rule  or
                    regulation  of  any  self-regulatory   organization,   stock
                    exchange  or  quotation  system on which the Rights may from
                    time to time be listed or  traded,  or to  conform to usage;
                    and

               (2)  a disclosure statement describing the Rights;

          provided that a Nominee  shall be sent the  materials  provided for in
          paragraphs  (1) and (2) above in respect of all Common  Shares held of
          record by it which are not Beneficially Owned by an Acquiring Person.

     d.   Rights may be  exercised in whole or in part on any Business Day after
          the Separation  Time and prior to the Expiration Time by submitting to
          the  Rights  Agent at its  principal  office in the city of Calgary or
          Toronto the Rights Certificate evidencing such Rights together with:


                                      -17-
<PAGE>
          i.   an election to exercise  such Rights (an  "Election to Exercise")
               substantially in the form attached to the Rights Certificate duly
               completed  and  executed  by  the  holder  or  his  executors  or
               administrators or other personal  representatives or his or their
               legal attorney duly appointed by an instrument in writing in form
               and executed in a manner satisfactory to the Rights Agent; and

          ii.  payment in cash or by certified cheque, bank draft or money order
               payable  to the order of the  Corporation,  of a sum equal to the
               Exercise Price multiplied by the number of Rights being exercised
               and a sum  sufficient  to cover any  transfer tax or charge which
               may be  payable  in  respect  of  any  transfer  involved  in the
               transfer or delivery of Rights  Certificates  or the  issuance or
               delivery of  certificates  for Common Shares in a name other than
               that of the holder of the Rights being exercised.

     e.   Upon  receipt  of a  Rights  Certificate,  which is  accompanied  by a
          completed  Election to Exercise that does not indicate that such Right
          is null and void as provided by  subsection  3.1(b) and payment as set
          forth  in  subsection  2.2(d),  the  Rights  Agent  (unless  otherwise
          instructed by the  Corporation  if the  Corporation  is of the opinion
          that the Rights cannot be exercised in accordance with this Agreement)
          will thereupon promptly:

          i.   requisition  from  the  transfer  agent  for  the  Common  Shares
               certificates  representing the number of such Common Shares to be
               purchased (the  Corporation  hereby  irrevocably  authorizing its
               transfer agent to comply with all such requisitions),

          ii.  after  receipt of such  certificate,  deliver the same to or upon
               the order of the  registered  holder of such Rights  Certificate,
               registered  in such  name or names as may be  designated  by such
               holder,

          iii. when appropriate,  requisition from the Corporation the amount of
               cash to be paid in lieu of issuing fractional Common Shares,

          iv.  when appropriate, after receipt of such cash, deliver the same to
               or  to  the  order  of  the  registered   holder  of  the  Rights
               Certificate, and

          v.   tender to the  Corporation  all payments  received on exercise of
               the Rights.

     f.   If the holder of any Rights  shall  exercise  less than all the Rights
          evidenced  by  such  holder's   Rights   Certificate,   a  new  Rights
          Certificate  evidencing the Rights remaining  unexercised  (subject to
          Section  5.5) will be issued by the Rights  Agent to such holder or to
          such holder's duly authorized assigns.

     g.   The Corporation covenants and agrees that it will:

          i.   take all such action as may be necessary  and within its power to
               ensure  that all  securities  delivered  upon  exercise of Rights
               shall,  at the  time of  delivery  of the  certificates  for such
               securities  (subject to payment of the Exercise  Price),  be duly
               and validly authorized,  executed,  issued and delivered as fully
               paid and non-assessable;


                                      -18-
<PAGE>
          ii.  take all such action as may be necessary  and within its power to
               comply  with  any   applicable   requirements   of  the  Business
               Corporations  Act, the Securities  Act (Alberta),  the Securities
               Act (Ontario) and any other applicable law in connection with the
               issuance and delivery of the Rights, the Rights  Certificates and
               the issuance of any securities upon exercise of Rights;

          iii. use  reasonable  efforts  to cause  all  securities  issued  upon
               exercise of Rights to be listed on the stock  exchanges  on which
               the Common  Shares  were  traded  immediately  prior to the Stock
               Acquisition Date;

          iv.  cause to be reserved and kept available out of its authorized and
               unissued classes of securities, the number of securities that, as
               provided in this Agreement,  will from time to time be sufficient
               to permit the exercise in full of all outstanding Rights;

          v.   pay when due and payable any and all Canadian and, if applicable,
               United States,  federal,  provincial and state transfer taxes and
               charges (not  including any income or capital taxes of the holder
               or  exercising  holder or any  liability  of the  Corporation  to
               withhold  tax) which may be  payable  in respect of the  original
               issuance or delivery of the Rights  Certificates  or certificates
               form Common Shares,  provided that the  Corporation  shall not be
               required to pay any  transfer  tax or charge which may be payable
               in respect of any  transfer  involved in the transfer or delivery
               of  Rights   Certificates   or  the   issuance   or  delivery  of
               certificates  for  securities  in a name  other  than that of the
               holder of the Rights being transferred or exercised; and

          vi.  after the  Separation  Time not take (or permit any Subsidiary to
               take)  any  action  if at the  time  such  action  is taken it is
               reasonably   foreseeable   that   such   action   will   diminish
               substantially or otherwise  eliminate the benefits intended to be
               afforded by the Rights.

2.3  ADJUSTMENTS TO EXERCISE PRICE; NUMBERS OF RIGHTS

The  Exercise  Price, the number and kind of securities subject to purchase upon
exercise  of  each  Right  and  the  number of Rights outstanding are subject to
adjustment  from  time  to  time  as  provided  in  this  Section  2.3.

     a.   If  Corporation  shall at any time after the Record  Time and prior to
          the Expiration Time:

          i.   declare or pay a dividend on its Common Shares  payable in Common
               Shares (or other securities  exchangeable for or convertible into
               or giving a right to acquire  Common  Shares) other than pursuant
               to any optional stock dividend program;

          ii.  subdivide or change the outstanding  Common Shares into a greater
               number of Common Shares;

          iii. combine or change the  outstanding  Common  Shares into a smaller
               number of Common Shares; or

          iv.  issue any Common Shares (or other securities  exchangeable for or
               convertible  into or giving a right to acquire  Common Shares) in
               respect of, in lieu of or in exchange for existing Common Shares;


                                      -19-
<PAGE>
          except as otherwise  provided in this Section 2.3, the Exercise  Price
          and the number of Rights outstanding,  or, if the payment or effective
          date therefor  shall occur after the  Separation  Time, the securities
          purchasable  upon  exercise  of  Rights  shall be  adjusted  as of the
          payment or effective date such that:

               (1)  if the Exercise Price and number of Rights  outstanding  are
                    to be adjusted;

                    (a)  the Exercise Price in effect after such adjustment will
                         be equal to the  Exercise  Price in effect  immediately
                         prior  to such  adjustment  divided  by the  number  of
                         Common Shares (or other capital stock) (the  "Expansion
                         Factor") that a holder of one Common Share  immediately
                         prior   to   such   dividend,   subdivision,    change,
                         combination  or  issuance  would hold  thereafter  as a
                         result thereof; and

                    (b)  each Right held prior to such  adjustment  will  become
                         that number of Rights equal to the Expansion Factor;

                    and the  adjusted  number  of  Rights  will be  deemed to be
                    distributed  among the Common  Shares with  respect to which
                    the  original   Rights  were   associated  (if  they  remain
                    outstanding)  and  the  shares  issued  in  respect  of such
                    dividend,  subdivision,  change, combination or issuance, so
                    that each such Common  Share (or other  capital  stock) will
                    have exactly one Right associated with it; and

               (2)  if the securities purchasable upon exercise of Rights are to
                    be adjusted,  the  securities  purchasable  upon exercise of
                    each Right after such adjustment will be the securities that
                    a holder of the securities  purchasable upon exercise of one
                    Right  immediately  prior  to  such  dividend,  subdivision,
                    change,  combination or issuance would hold  thereafter as a
                    result thereof.

          If  after  the  Record  Time  and  prior  to the  Expiration  Time the
          Corporation  shall issue any securities  other than Common Shares in a
          transaction of a type described in paragraphs  2.3(a)(i) or (iv), such
          securities  shall be  treated  herein as nearly  equivalent  to Common
          Shares as may be practicable and appropriate  under the  circumstances
          and the Corporation and the Rights Agent agree to amend this Agreement
          in order to effect such treatment.

     b.   If the  Corporation  shall at any time after the Record Time and prior
          to the  Separation  Time fix a record date for the issuance of rights,
          options or  warrants to all holders of Common  Shares  entitling  them
          (for a period expiring within 45 calendar days after such record date)
          to subscribe for or purchase Common Shares (or securities  convertible
          into or  exchangeable  for or  carrying  a right  to  purchase  Common
          Shares) at a price per Common  Share  (or,  if a security  convertible
          into or exchangeable  for or carrying a right to purchase or subscribe
          for Common  Shares having a  conversion,  exchange or exercise  price,
          including the price  required to be paid to purchase such  convertible
          or  exchangeable  security  or right per  share)  less than the Market
          Price per Common Share on such record date,  the Exercise  Price to be
          in effect  after  such  record  date shall be  adjusted  to that price
          determined by  multiplying  the Exercise  Price in effect  immediately
          prior to such record date by a fraction:


                                      -20-
<PAGE>
          i.   the  numerator  of which  shall be the  number of  Common  Shares
               outstanding on such record date, plus the number of Common Shares
               that the aggregate  offering  price of the total number of Common
               Shares to be so offered (and/or the aggregate initial conversion,
               exchange or exercise  price of the  convertible  or  exchangeable
               securities  or  rights  so to be  offered,  including  the  price
               required to be paid to purchase such  convertible or exchangeable
               securities  or rights)  would  purchase at such Market  Price per
               Common Share; and

          ii.  the  denominator  of which  shall be the number of Common  Shares
               outstanding  on such record date,  plus the number of  additional
               Common Shares to be offered for subscription or purchase (or into
               which the convertible or exchangeable  securities or rights so to
               be   offered   are   initially   convertible,   exchangeable   or
               exercisable).

          If such  subscription  price may be paid by delivery of consideration,
          part or all of which may be in a form other  than  cash,  the value of
          such  consideration  shall be as determined in good faith by the Board
          of Directors,  whose  determination  shall be described in a statement
          filed with the Rights  Agent and shall be binding on the Rights  Agent
          and  the  holders  of  the  Rights.  Such  adjustment  shall  be  made
          successively  whenever  such a record date is fixed,  and in the event
          that such rights or warrants  are not so issued,  the  Exercise  Price
          shall be  adjusted  to be the  Exercise  Price  which would then be in
          effect if such record date had not been fixed.

          For purposes of this Agreement,  the granting of the right to purchase
          Common Shares (whether from treasury shares or otherwise)  pursuant to
          any  dividend or interest  reinvestment  plan and/or any Common  Share
          purchase plan providing for the  reinvestment of dividends or interest
          payable on  securities  of the  Corporation  and/or the  investment of
          periodic optional  payments and/or employee  benefit,  stock option or
          similar  plans  (so  long  as such  right  to  purchase  is in no case
          evidenced by the  delivery of rights or warrants)  shall not be deemed
          to  constitute  an issue of rights  or  warrants  by the  Corporation;
          provided,  however,  that,  in the case of any  Dividend  Reinvestment
          Plan,  the right to purchase  Common Shares is at a price per share of
          not less  than 90  percent  of the  current  market  price  per  share
          (determined as provided in such plans) of the Common Shares.

     c.   If the  Corporation  shall at any time after the Record Time and prior
          to the  Separation  Time fix a record date for a  distribution  to all
          holders of Common  Shares  (including  any such  distribution  made in
          connection  with a merger or  amalgamation in which the Corporation is
          the continuing corporation) of evidences of indebtedness,  cash (other
          than  an  ordinary  course  dividend  or a  dividend  referred  to  in
          paragraph  2.3(a)(i)),  assets,  rights or warrants  (excluding  those
          referred to in subsection 2.3(b)),  the Exercise Price to be in effect
          after such record date shall be determined by multiplying the Exercise
          Price in effect immediately prior to such record date by a fraction:

          i.   the numerator of which shall be the Market Price per Common Share
               on such record date, less the fair market value (as determined in
               good faith by the Board of Directors,  whose  determination shall
               be described in a statement filed with the Rights Agent and shall
               be binding on the Rights  Agent and the holders of Rights),  on a
               per share basis, of the portion of the cash, assets, evidences of
               indebtedness,  rights,  options or warrants so to be distributed;
               and

          ii.  the  denominator  of which shall be such Market  Price per Common
               Share.


                                      -21-
<PAGE>
          Such  adjustments  shall be made  successively  whenever such a record
          date is fixed,  and in the event  that such a  distribution  is not so
          made,  the Exercise  Price shall be adjusted to be the Exercise  Price
          which  would  have  been in effect  if such  record  date had not been
          fixed.

     d.   Each adjustment made pursuant to this Section 2.3 shall be made as of:

          i.   the  payment  or  effective  date  for the  applicable  dividend,
               subdivision,  change,  combination or issuance, in the case of an
               adjustment made pursuant to subsection (a) above; and

          ii.  the record date for the applicable  distribution,  in the case of
               an  adjustment  made  pursuant  to  subsection  (b) or (c) above,
               subject to readjustment to reverse the same if such  distribution
               shall not be made.

     e.   Notwithstanding  anything herein to the contrary, no adjustment in the
          Exercise Price shall be required unless such adjustment  would require
          an increase or decrease of at least one percent in the Exercise Price;
          provided,  however,  that  any  adjustments  which by  reason  of this
          subsection 2.3(e) are not required to be made shall be carried forward
          and taken into account in any subsequent adjustment.  All calculations
          under this  Section  2.3 shall be made to the  nearest  cent or to the
          nearest  hundredth of a share.  Notwithstanding  the first sentence of
          this subsection  2.3(e),  any adjustment  required by this Section 2.3
          shall be made no later than the  earlier  of: (i) three years from the
          date of the transaction which mandates such adjustments;  and (ii) the
          Termination Date. Whenever an adjustment to the Exercise Price is made
          pursuant to this Section 2.3, the Corporation shall:

          i.   promptly prepare a certificate  setting forth such adjustment and
               a brief statement of the facts accounting for such adjustment,

          ii.  promptly file with the Rights Agent and with each transfer  agent
               for the Common Shares a copy of such certificate and mail a brief
               summary thereof to each holder of Rights.

     f.   If the  Corporation  shall at any time after the Record Time and prior
          to the  Separation  Time issue any shares of capital stock (other than
          Common Shares), or rights or warrants to subscribe for or purchase any
          such capital stock, or securities convertible into or exchangeable for
          any such  capital  stock,  in a  transaction  referred to in paragraph
          (a)(i) or  (a)(iv)  above,  if the Board of  Directors  acting in good
          faith determines that the adjustments contemplated by subsections (a),
          (b) and (c)  above  in  connection  with  such  transaction  will  not
          appropriately  protect the  interests  of the  holders of Rights,  the
          Corporation  may  determine  what other  adjustments  to the  Exercise
          Price, number of Rights and/or securities purchasable upon exercise of
          Rights would be appropriate and, notwithstanding  subsections (a), (b)
          and  (c)  above,  such   adjustments,   rather  than  the  adjustments
          contemplated by subsections (a), (b) and (c) above, shall be made. The
          Corporation  and the  Rights  Agent  shall  amend  this  Agreement  as
          appropriate to provide for such adjustments.

     g.   Each Right  originally  issued by the  Corporation  subsequent  to any
          adjustment  made to the Exercise  Price  hereunder  shall evidence the
          right to  purchase,  at the  adjusted  Exercise  Price,  the number of
          Common Shares purchasable from time to time hereunder upon exercise of
          a Right, all subject to further adjustment as provided herein.

     h.   Irrespective  of any adjustment or change in the Exercise Price or the
          number of Common Shares issuable upon the exercise of the Rights,  the
          Rights  Certificates issued before and after such adjustment or change
          may  continue to express the  Exercise  Price per Common Share and the
          number of Common  Shares which were  expressed  in the initial  Rights
          Certificates issued hereunder.

     i.   In any case in which this Section 2.3 shall require that an adjustment
          in the  Exercise  Price be made  effective  as of a record  date for a
          specified  event,  the  Corporation  may  elect  to  defer  until  the
          occurrence  of such  event  the  issuance  to the  holder of any Right
          exercised after such record date the number of Common Shares and other
          securities  of the  Corporation,  if any,  issuable upon such exercise
          over and above the number of Common Shares and other securities of the
          Corporation,  if any,  issuable upon such exercise on the basis of the
          Exercise Price in effect prior to such adjustment;  provided, however,
          that the  Corporation  shall  deliver  to such  holder an  appropriate
          instrument  evidencing  such holder's right to receive such additional
          shares  (fractional or otherwise) or securities upon the occurrence of
          the event requiring such adjustment.

     j.   Notwithstanding  anything  in this  Section 2.3 to the  contrary,  the
          Corporation  shall be entitled to make such reductions in the Exercise
          Price,  in addition to those  adjustments  expressly  required by this
          Section 2.3, as and to the extent that the Board of Directors shall in
          good  faith   determine   to  be  advisable  in  order  that  any  (i)
          consolidation  or  subdivision  of the Common  Shares,  (ii)  issuance
          wholly or in part for cash of  Common  Shares  or  securities  that by
          their terms are convertible  into or  exchangeable  for Common Shares,
          (iii) stock dividends or (iv) issuance of rights,  options or warrants
          referred to in this Section 2.3,  hereafter made by the Corporation to
          holders   of  its  Common   Shares   shall  not  be  taxable  to  such
          shareholders.

     k.   The Corporation  covenants and agrees that, after the Separation Time,
          it will not,  except as permitted by Section 5.1 or Section 5.3,  take
          (or permit any Subsidiary of the Corporation to take) any action if at
          the time such action is taken it is reasonably  foreseeable  that such
          action will diminish substantially or otherwise eliminate the benefits
          intended to be afforded by the Rights.

     l.   If an event occurs which would require an  adjustment  under both this
          Section 2.3 and  Section  3.1,  the  adjustment  provided  for in this
          Section  2.3 shall be in  addition  to and shall be made prior to, any
          adjustment required pursuant to Section 3.1.

     m.   If the  Corporation  shall at any time after the Record Time and prior
          to the earlier of the Separation  Time and the  Expiration  Time issue
          any  Common  Shares  other  than  in  a  transaction  referred  to  in
          subsection 2.3(a) each such Common Share so issued shall automatically
          have one new Right  associated with it, which Right shall be evidenced
          by the certificate representing such share.


                                      -23-

2.4  DATE ON WHICH EXERCISE IS EFFECTIVE

Each Person in whose name any certificate for Common Shares or other securities,
property  or  assets, if applicable, is issued upon the exercise of Rights shall
for  all  purposes  be deemed, to have become the holder of record of the Common
Shares  or  other  securities,  property  or  assets, if applicable, represented
thereby  on, and such certificate shall be dated, the date upon which the Rights
Certificate  evidencing  such  Rights was duly surrendered (together with a duly
completed  Election  to  Exercise)  and  payment  of the Exercise Price for such
Rights (and any applicable transfer taxes and other governmental charges payable
by  the  exercising  holder  hereunder) was made; provided, however, that if the
date  of  such  surrender  and  payment  is  a  date upon which the Common Share
transfer  books  of  the  Corporation are closed, such Person shall be deemed to
have  become  the  record  holder  of  such  Common  Shares or other securities,
property  or assets on, and such certificate shall be dated, the next succeeding
Business  Day  on  which  the Common Share transfer books of the Corporation are
open.

2.5  EXECUTION, AUTHENTICATION, DELIVERY AND DATING OF RIGHTS CERTIFICATES

     a.   The Rights Certificates shall be executed on behalf of the Corporation
          by any two of its officers or directors. The signature of any of these
          officers  or  directors  on the Rights  Certificates  may be manual or
          facsimile.   Rights  Certificates  bearing  the  manual  or  facsimile
          signatures of individuals  who were at any time the proper officers or
          directors   of   the   Corporation    shall   bind   the   Corporation
          notwithstanding  that such  individuals  or any of them have ceased to
          hold such offices prior to the  countersignature  and delivery of such
          Rights Certificates.

     b.   Promptly  after the  Corporation  learns of the  Separation  Time, the
          Corporation will notify the Rights Agent in writing of such Separation
          Time and will deliver Rights Certificates  executed by the Corporation
          to the Rights Agent for  countersignature,  and the Rights Agent shall
          manually  countersign and send such Rights Certificates to the holders
          of the Rights  pursuant to subsection  2.2(c).  No Rights  Certificate
          shall be valid for any purpose until countersigned by the Rights Agent
          as aforesaid.

     c.   Each Rights  Certificate  shall be dated the date of  countersignature
          thereof.

2.6  REGISTRATION, REGISTRATION OF TRANSFER AND EXCHANGE

     a.   After the  Separation  Time, the  Corporation  will cause to be kept a
          register (the "RIGHTS REGISTER") in which,  subject to such reasonable
          regulations as it may prescribe,  the Corporation will provide for the
          registration  and  transfer  of  Rights.  The  Rights  Agent is hereby
          appointed  registrar for the Rights (the "Rights  Registrar")  for the
          purpose of maintaining  the Rights  Register for the  Corporation  and
          registering  Rights and transfers of Rights as herein provided and the
          Rights Agent  hereby  accepts  such  appointment.  If the Rights Agent
          shall cease to be the Rights Registrar, the Rights Agent will have the
          right to examine the Rights Register at all reasonable times.

     b.   After the  Separation  Time and  prior to the  Expiration  Time,  upon
          surrender  for  registration  of  transfer  or  exchange of any Rights
          Certificate,  and subject to the provisions of subsections  2.6(d) and
          3.1(b),  the  Corporation  will  execute,  and the  Rights  Agent will
          manually  countersign  and  deliver,  in the name of the holder or the
          designated  transferee  or  transferees,  as required  pursuant to the
          holder's instructions,  one or more new rights Certificates evidencing
          the same aggregate number of Rights as did the Rights  Certificates so
          surrendered.


                                      -24-
<PAGE>
     c.   All Rights  issued  upon any  registration  of transfer or exchange of
          Rights Certificates shall be valid obligations of the Corporation, and
          such  Rights  shall  be  entitled  to the  same  benefits  under  this
          Agreement as the Rights surrendered upon such registration of transfer
          or exchange.

     d.   Every Rights  Certificate  surrendered for registration of transfer or
          exchange  shall  be duly  endorsed,  or be  accompanied  by a  written
          instrument of transfer in form  satisfactory to the Corporation or the
          Rights Agent,  as the case may be, duly executed by the holder thereof
          or such holder's  attorney duly authorized in writing.  As a condition
          to the issuance of any new Rights  Certificate under this Section 2.6,
          the  Corporation  may require the payment of a sum sufficient to cover
          any tax or other  governmental  charge that may be imposed in relation
          thereto and any other expenses (including the fees and expenses of the
          Rights Agent) connected therewith.

2.7  MUTILATED, DESTROYED, LOST AND STOLEN RIGHTS CERTIFICATES

     a.   If any mutilated Rights Certificate is surrendered to the Rights Agent
          prior to the Expiration  Time, the  Corporation  shall execute and the
          Rights Agent shall  countersign and deliver in exchange therefor a new
          Rights Certificate  evidencing the same number of Rights as the Rights
          Certificate so surrendered.

     b.   If there shall be  delivered to the  Corporation  and the Rights Agent
          prior to the Expiration Time:

          i.   evidence to their  reasonable  satisfaction  of the  destruction,
               loss or theft of any Rights Certificate; and

          ii.  such security or indemnity as may be reasonably  required by them
               in their  sole  discretion  to save each of them and any of their
               agents harmless,

          then, in the absence of notice to the  Corporation or the Rights Agent
          that  such  Rights  Certificate  has  been  acquired  by a  bona  fide
          purchaser,  the Corporation  shall execute and upon the  Corporation's
          request the Rights Agent shall countersign and deliver, in lieu of any
          such  destroyed,  lost or  stolen  Rights  Certificate,  a new  Rights
          Certificate  evidencing  the same  number of Rights as did the  Rights
          Certificate so destroyed, lost or stolen.

     c.   As a condition  to the  issuance of any new Rights  Certificate  under
          this  Section 2.7,  the  Corporation  may require the payment of a sum
          sufficient to cover any tax or other  governmental  charge that may be
          imposed in relation thereto and any other expenses (including the fees
          and expenses of the Rights Agent) connected therewith.

     d.   Every new Rights  Certificate  issued  pursuant to this Section 2.7 in
          lieu  of any  destroyed,  lost  or  stolen  Rights  Certificate  shall
          evidence the contractual obligation of the Corporation, whether or not
          the destroyed,  lost or stolen Rights Certificate shall be at any time
          enforceable  by anyone,  and shall be entitled to all the  benefits of
          this  Agreement  equally  and  proportionately  with any and all other
          Rights duly issued by the Corporation.


                                      -25-
<PAGE>
2.8  PERSONS DEEMED OWNERS

The Corporation, the Rights Agent and any agent of the Corporation or the Rights
Agent  may  deem  and  treat  the Person in whose name a Rights Certificate (or,
prior  to  the  Separation  Time,  the  associated  Common Share certificate) is
registered  as  the  absolute owner thereof and the Rights evidenced thereby for
all  purposes  whatsoever.  As  used  in  this  Agreement,  unless  the  context
otherwise  requires,  the  term "HOLDER" of any Rights shall mean the registered
holder  of  such Rights (or, prior to the Separation Time, the associated Common
Shares).

2.9  DELIVERY AND CANCELLATION OF CERTIFICATES

All  Rights  Certificates  surrendered  upon  exercise  or  for  redemption,
registration  of  transfer or exchange shall, if surrendered to any Person other
than  the Rights Agent, be delivered to the Rights Agent and, in any case, shall
be  promptly  canceled  by  the  Rights  Agent.  The Corporation may at any time
deliver  to the Rights Agent for cancellation any Rights Certificates previously
countersigned and delivered hereunder which the Corporation may have acquired in
any  manner  whatsoever,  and  all  Rights  Certificates  so  delivered shall be
promptly  canceled  by  the  Rights  Agent.  No  Rights  Certificate  shall  be
countersigned  in lieu of or in exchange for any Rights Certificates canceled as
provided  in  this Section 2.9, except as expressly permitted by this Agreement.
The  Rights  Agent  shall destroy all canceled Rights Certificates and deliver a
certificate  of  destruction  to  the  Corporation.

2.10 AGREEMENT OF RIGHTS HOLDERS

Every  holder  of  Rights,  by  accepting the same, consents and agrees with the
Corporation  and  the  Rights  Agent  and  with  every  other  holder of Rights:

     a.   to be bound by and subject to the  provisions  of this  Agreement,  as
          amended  from time to time in  accordance  with the terms  hereof,  in
          respect of all Rights held;

     b.   that,  prior to the Separation  Time,  each Right will be transferable
          only  together  with,  and will be  transferred  by a transfer of, the
          associated Common Share;

     c.   that  after  the  Separation  Time,  the  Rights  Certificate  will be
          transferable  only upon  registration  of the  transfer  on the Rights
          Register as provided herein;

     d.   that,  prior to due presentment of a Rights  Certificate (or, prior to
          the  Separation  Time, the associated  Common Share  certificate)  for
          registration of transfer,  the  Corporation,  the Rights Agent and any
          agent of the  Corporation  or the Rights  Agent may deem and treat the
          person  in  whose  name  the  Rights  Certificate  (or,  prior  to the
          Separation   Time,  the  associated   Common  Share   certificate)  is
          registered as the absolute  owner thereof and of the Rights  evidenced
          thereby (notwithstanding any notations of ownership or writing on such
          Rights  Certificate or the associated Common Share certificate made by
          anyone  other  than  the  Corporation  or the  Rights  Agent)  for all
          purposes whatsoever,  and neither the Corporation nor the Rights Agent
          shall be affected by any notice to the contrary;

     e.   that such  holder of  Rights  has  waived  his  right to  receive  any
          fractional  Rights or any  fractional  shares upon exercise of a Right
          except as provided herein;

     f.   that,  without the  approval of any holder of Rights and upon the sole
          authority  of the  Board  of  Directors  acting  in good  faith,  this
          Agreement may be supplemented or amended from time to time pursuant to
          and as provided herein; and


                                      -26-
<PAGE>
     g.   that,  notwithstanding  anything in this  Agreement  to the  contrary,
          neither the  Corporation nor the Rights Agent shall have any liability
          to any  holder  of a Right or any  other  Person  as a  result  of its
          inability to perform any of its  obligations  under this  Agreement by
          reason of any  preliminary  or  permanent  injunction  or other order,
          decree or ruling issued by a court of competent  jurisdiction  or by a
          governmental,  regulatory or administrative  agency or commission,  or
          any statute,  rule,  regulation  or  executive  order  promulgated  or
          enacted  by  any  governmental  authority,  prohibiting  or  otherwise
          restraining performance of such obligation.

2.11 RIGHTS CERTIFICATE HOLDER NOT DEEMED A SHAREHOLDER

No  holder,  as  such,  of any Rights or Rights Certificate shall be entitled to
vote,  receive  dividends  or be deemed for any purpose whatsoever the holder of
any  Common Share or any other share or security of the Corporation which may at
any  time  be  issuable  on  the exercise of the Rights represented thereby, nor
shall  anything  contained  herein  or in any Rights Certificate be construed or
deemed  or  confer  upon the holder of any Right or Rights Certificate, as such,
any  of  the rights, titles, benefits or privileges of a holder of Common Shares
or any other shares or securities of the Corporation or any right to vote at any
meeting of shareholders of the Corporation whether for the election of directors
or  otherwise  or  upon  any  matter  submitted  to  holders  of  shares  of the
Corporation at any meeting thereof, or to give or withhold consent to any action
of  the  Corporation,  or  to  receive  notice  of  any  meeting or other action
affecting  any  holder of Common Shares or any other shares or securities of the
Corporation  except  as  expressly  provided  herein,  or  to receive dividends,
distributions  or  subscription  rights, or otherwise, until the Right or Rights
evidenced  by  Rights  Certificates shall have been duly exercised in accordance
with  the  terms  and  provisions  hereof.

                                  ARTICLE  3
     ADJUSTMENTS  TO  THE  RIGHTS  IN  THE  EVENT  OF  CERTAIN  TRANSACTIONS

3.1  FLIP-IN EVENT

     a.   Subject to subsection  3.1(b),  Section 3.2 and subsections 5.1(d) and
          5.1(e),  if prior to the Expiration Time a Flip-in Event occurs,  each
          Right  shall  constitute,  effective  at the close of  business on the
          tenth Trading Day after the Stock  Acquisition Date, on and after such
          occurrence the right to purchase from the Corporation, upon payment of
          the Exercise Price and otherwise  exercising  such Right in accordance
          with the  terms  hereof,  that  number  of  Common  Shares  having  an
          aggregate  Market Price on the date of  consummation  or occurrence of
          such Flip-in Event equal to twice the Exercise  Price for an amount in
          cash  equal to the  Exercise  Price  (such  Right to be  appropriately
          adjusted in a manner analogous to the applicable  adjustment  provided
          for in Section 2.3 in event that after the Stock  Acquisition  Date an
          event of a type  analogous  to any of the events  described in Section
          2.3 have occurred).

     b.   Notwithstanding  anything in this Agreement to the contrary,  upon the
          occurrence  of  any  Flip-in  Event,  any  Rights  that  are  or  were
          Beneficially  Owned on or after the earlier of the Separation Time and
          the Stock Acquisition Date by:

          i.   an  Acquiring  Person  (or  any  Affiliate  or  Associate  of  an
               Acquiring  Person or any Person acting jointly or in concert with
               an Acquiring Person or any Associate or Affiliate of an Acquiring
               Person); or


                                      -27-
<PAGE>
          ii.  a  transferee  of Rights,  direct or  indirect,  of an  Acquiring
               Person (or of any  Affiliate or Associate of an Acquiring  Person
               or of any Person  acting  jointly or in concert with an Acquiring
               Person or any Associate or Affiliate of an Acquiring  Person) who
               becomes a  transferee  in a transfer  that the Board of Directors
               has  determined  is part of a plan,  arrangement  or scheme of an
               Acquiring  Person (or any  Affiliate or Associate of an Acquiring
               Person  or any  Person  acting  jointly  or in  concert  with  an
               Acquiring  Person or any  Associate  or Affiliate of an Acquiring
               Person),  that has the  purpose or effect of  avoiding  paragraph
               3.1(b)(i);

          shall become null and void without any further action,  and any holder
          of such Rights  (including any  transferee of, or other  successor to,
          such Rights,  whether directly or indirectly) shall not have any right
          whatsoever  to  exercise  such  Rights  under  any  provision  of this
          Agreement  and shall not have  thereafter  any right  whatsoever  with
          respect to such Rights,  whether under any provision of this Agreement
          or  otherwise.  The  holder  of any  Rights  represented  by a  Rights
          Certificate  which is submitted  to the Rights Agent upon  exercise or
          for  registration  of transfer or exchange  which does not contain the
          necessary   certifications   set  forth  in  the  Rights   Certificate
          establishing  that such  Rights  are not void  under  this  subsection
          3.1(b) shall be deemed to be an  Acquiring  Person for the purposes of
          this subsection 3.1(b) and such Rights shall become null and void.

     c.   Any Rights Certificate that represents Rights  Beneficially Owned by a
          Person described in either paragraph  3.1(b)(i) or (ii) or transferred
          to any Nominee of any such Person,  and any Rights  Certificate issued
          upon transfer, exchange, replacement or adjustment of any other Rights
          Certificate referred to in this sentence,  shall contain the following
          legend:

               The  Rights   represented   by  this  Rights   Certificate   were
               Beneficially  Owned by a Person who was an Acquiring Person or an
               Affiliate or an  Associate of an Acquiring  Person (as such terms
               are  defined  in the  Rights  Agreement)  or by a  Person  acting
               jointly or in concert with any of them.  This Rights  Certificate
               and the Rights  represented  hereby are void in the circumstances
               specified in subsection 3.1(b) of the Rights Agreement.

          provided  that the Rights Agent shall not be under any  responsibility
          to ascertain the existence of facts that would require the  imposition
          of such  legend but shall be  required  to impose  such legend only if
          instructed to do so in writing by the Corporation or if a holder fails
          to certify  upon  transfer or  exchange  in the space  provided on the
          Rights  Certificate  that  such  holder is not a Person  described  in
          either paragraph 3.1(b)(i) or (ii).

     d.   In the  event  that  there  shall  not  be  sufficient  Common  Shares
          authorized  for  issuance to permit the exercise in full of the Rights
          in accordance  with this Section 3.1, the  Corporation  shall take all
          such action as may be necessary to authorize  additional Common Shares
          for issuance upon the exercise of the Rights,  failing which the Board
          of Directors  shall  consider the exercise of the options set forth in
          Section 3.2.


                                      -28-
<PAGE>
     e.   From and after the Separation Time, the Corporation  shall do all such
          acts and things as shall be  necessary  and within its power to ensure
          compliance with the provisions of this Section 3.1,  including without
          limitation, all such acts and things as may be required to satisfy the
          requirements of the Business  Corporations  Act and the Securities Act
          (Alberta)  and any other  applicable  law in  respect  of the issue of
          Common  Shares  upon the  exercise of Rights in  accordance  with this
          Agreement.

3.2  EXCHANGE OPTION

     a.   Subject to receipt by the  Corporation  of the written  consent of The
          Toronto Stock Exchange, if the Board of Directors acting in good faith
          shall  determine  that  conditions  exist  which  would  eliminate  or
          otherwise  materially diminish in any respect the benefits intended to
          be afforded to the holders of Rights  pursuant to this  Agreement  the
          Board of Directors may, at its option and without seeking the approval
          of  holders of Common  Shares or  Rights,  at any time after a Flip-in
          Event has occurred,  authorize the  Corporation to issue or deliver in
          respect of each Right which is not void pursuant to subsection 3.1(b),
          either:

          i.   in return for the Exercise Price and the Right,  debt,  equity or
               other securities or property or assets (or a combination thereof)
               having a value equal to twice the Exercise Price; or

          ii.  in return  for the  Right,  subject  to any  amounts  that may be
               required to be paid under applicable law, cash,  debt,  equity or
               other securities or property or assets (or a combination thereof)
               having a value equal to the Exercise Price;

          in full and final  settlement  of all rights  attaching to the Rights;
          provided  that the value of any debt,  equity or other  securities  or
          properties   or  assets  shall  be   determined  by  a  nationally  or
          internationally  recognized  Canadian  firm of  investment  dealers or
          investment  bankers selected by the Board of Directors.  To the extent
          that the Board of Directors  determines in good faith that some action
          need be taken pursuant to this Section 3.2, the Board of Directors may
          suspend the  exercisability of the Rights for a period of up to ninety
          days  following  the date of the  occurrence  of the relevant  Flip-in
          Event in order to decide the  appropriate  form of  distribution to be
          made and to  determine  the  value  thereof.  In the event of any such
          suspension, the Corporation shall notify the Rights Agent and issue as
          promptly  as  practicable  a  public  announcement  stating  that  the
          exercisability of the Rights has been temporarily suspended.

     b.   If the Board of Directors  authorizes the exchange of debt,  equity or
          other  securities  or  property or assets (or a  combination  thereof)
          pursuant to subsection  3.2(a),  without any further  action or notice
          the only right  thereafter  of a holder of Rights  shall be to receive
          upon due exercise of the Rights such debt,  equity or other securities
          or property or assets (or a combination  thereof) in  accordance  with
          the  determination of the Board of Directors.  Within 10 Business Days
          after the Board of Directors has authorized the exchange of such debt,
          equity or other  securities  or property  or assets (or a  combination
          thereof)  pursuant to subsection  3.2(a),  the Corporation  shall give
          notice of such  exchange to the holders of Rights in  accordance  with
          Section  5.9.  Each such  notice  will  state the  method by which the
          exchange of debt, equity or other securities or property or assets (or
          a combination thereof) for Rights will be effected.


                                      -29-

     c.   If there shall not be sufficient securities authorized but unissued to
          permit the  exchange in full of such Rights  pursuant to this  Section
          3.2, the Corporation shall take all such action as may be necessary to
          authorize  additional  securities  for  issuance  upon the exchange of
          Rights.

     d.   The Corporation shall not be required to issue fractions of securities
          or to distribute  certificates  evidencing fractional  securities.  In
          lieu of issuing  such  fractional  securities,  subject to  subsection
          5.5(b),  there  shall be paid to the  registered  holders of Rights to
          whom such fractional securities would otherwise be issuable, an amount
          in cash  equal to the same  fraction  of the  Market  Price of a whole
          security.

3.3  FIDUCIARY DUTIES OF THE BOARD OF DIRECTORS OF THE CORPORATION

Nothing contained in this Article 3 shall be considered to affect the obligation
of  the  Board  of Directors to exercise its fiduciary duties.  Without limiting
the  generality of the foregoing, nothing contained herein shall be construed to
suggest  or imply that the Board of Directors shall not be entitled to recommend
that holders of the Voting Shares reject or accept any Take-over Bid or take any
other  action  (including,  without  limitation,  the commencement, prosecution,
defence  or  settlement  of  any  litigation and the submission of additional or
alternative  Take-over  Bids  or  other  proposals  to  the  shareholders of the
Corporation  with  respect  to  any  Take-over  Bid) that the Board of Directors
believes  is  necessary  or appropriate in the exercise of its fiduciary duties.

                                  ARTICLE 4
                              THE RIGHTS AGENT

4.1  GENERAL

     a.   The  Corporation  hereby appoints the Rights Agent to act as agent for
          the  Corporation in accordance  with the terms and conditions  hereof,
          and the Rights Agent hereby accepts such appointment.  The Corporation
          may  from  time to time  appoint  such  co-Rights  Agents  ("Co-Rights
          Agents")  as it may deem  necessary  or  desirable.  In the  event the
          Corporation  appoints one or more  Co-Rights  Agents,  the  respective
          duties of the Rights Agents and the  Co-Rights  Agents shall be as the
          Corporation may determine. The Corporation agrees to pay to the Rights
          Agent  reasonable   compensation  for  all  services  rendered  by  it
          hereunder  and, from time to time, on demand of the Rights Agent,  its
          reasonable expenses and counsel fees and other disbursements  incurred
          in the administration and execution of this Agreement and the exercise
          and performance of its duties hereunder, including the reasonable fees
          and  disbursements  of any expert  retained by the Rights  Agent.  The
          Corporation also agrees to indemnify the Rights Agent for, and to hold
          it harmless against,  any loss,  liability,  costs,  claims,  actions,
          damages or expenses,  incurred without negligence, bad faith or wilful
          default on the part of the Rights Agent, for anything done or suffered
          or omitted  by the Rights  Agent in  connection  with the  acceptance,
          execution and  administration of this Agreement and the performance of
          its duties  hereunder,  including  the costs and expenses of defending
          against any claim of liability,  which right to  indemnification  will
          survive the  termination of this  Agreement or the  resignation of the
          Rights Agent.


                                      -30-
<PAGE>
     b.   The Rights Agent shall be protected  and shall incur no liability  for
          or in  respect  of any  action  taken,  suffered  or  omitted by it in
          connection with its acceptance,  execution and  administration of this
          Agreement in reliance upon any certificate for Voting Shares or Common
          Shares, or any Rights  Certificate or certificate for other securities
          of the  corporation,  instrument of  assignment or transfer,  power of
          attorney, endorsement,  affidavit, letter, notice, direction, consent,
          certificate,  statement,  or other paper or document believed by it to
          be genuine and to be signed,  executed and, where necessary,  verified
          or acknowledged, by the proper Person or Persons.

     c.   The Corporation  shall inform the Rights Agent in a reasonably  timely
          manner of events which may  materially  affect the  administration  of
          this Agreement by the Rights Agent.

4.2  MERGER OR AMALGAMATION OR CHANGE OF NAME OF RIGHTS AGENT

a.   Any corporation  into which the Rights Agent or any successor  Rights Agent
     may be merged or amalgamated or with which it may be  consolidated,  or any
     corporation resulting from any merger, amalgamation,  statutory arrangement
     or consolidation to which the Rights Agent or any successor Rights Agent is
     a party,  or any  corporation  succeeding to the shareholder or stockholder
     services  business of the Rights Agent or any successor Rights Agent,  will
     be the  successor  to the Rights  Agent  under this  Agreement  without the
     execution  or filing of any paper or any  further act on the part of any of
     the parties hereto,  provided that such  corporation  would be eligible for
     appointment  as a successor  Rights Agent under the  provisions  of Section
     4.4.  If at the time any  successor  Rights  Agent  succeeds  to the agency
     created  by  this  Agreement  any  of  the  Right  Certificates  have  been
     countersigned but not delivered,  any such successor Rights Agent may adopt
     the  countersignature  of the  predecessor  Rights  Agent and deliver  such
     Rights Certificates so countersigned;  and if at that time any of the Right
     Certificates  have not been  countersigned,  any successor Rights Agent may
     countersign such Right  Certificates  either in the name of the predecessor
     Rights Agent or in the name of the successor  Rights Agent; and in all such
     cases such Right  Certificates  will have the full  force  provided  in the
     Right Certificates and in this Agreement.

b.   If at any time the name of the Rights Agent is changed and at such time any
     of the Right  Certificates shall have been countersigned but not delivered,
     the Rights  Agent may adopt the  countersignature  under its prior name and
     deliver Right Certificates so countersigned; and if at that time any of the
     Right Certificate shall not have been  countersigned,  the Rights Agent may
     countersign  such  Right  Certificates  either in its prior  name or in its
     changed name; and in all such cases such Right  Certificates shall have the
     full force provided in the Right Certificates and in this Agreement.

4.3  DUTIES OF RIGHTS AGENT

The Rights Agent undertakes the duties and obligations imposed by this Agreement
upon the following terms and conditions, by all of which the Corporation and the
holders  of  Right  Certificates,  by  their acceptance thereof, shall be bound:


                                      -31-
<PAGE>
a.   the Rights Agent may consult with legal  counsel (who may be legal  counsel
     for the  Corporation)  and the  opinion  of such  counsel  will be full and
     complete  authorization and protection to the Rights Agent as to any action
     taken,  suffered or omitted by it in good faith and in accordance with such
     opinion;  the Rights Agent may also,  with the approval of the  Corporation
     (such approval not to be  unreasonably  withheld),  consult with such other
     experts as the Rights  Agent shall  consider  necessary or  appropriate  to
     properly carry out the duties and obligations  imposed under this Agreement
     and the Rights  Agent shall be entitled to rely in good faith on the advice
     of any such expert;

b.   whenever in the  performance  of its duties under this Agreement the Rights
     Agent deems it necessary or desirable  that any fact or matter be proved or
     established  by the  Corporation  prior to taking or  suffering  any action
     hereunder, such fact or matter (unless other evidence in respect thereof be
     herein specifically prescribed) may be deemed to be conclusively proved and
     established  by a  certificate  signed by a Person  believed  by the Rights
     Agent to be the  Chairman,  the  President  or any Vice  President,  or the
     Secretary or Assistant  Secretary of the  Corporation  and delivered to the
     Rights Agent; and such certificate will be full authorization to the Rights
     Agent  for any  action  taken or  suffered  in good  faith by it under  the
     provisions of this Agreement in reliance upon such certificate;

c.   the Rights Agent will be liable hereunder only for its own negligence,  bad
     faith or wilful default;

d.   the  Rights  Agent  will  not  be  liable  for or by  reason  of any of the
     statements  of fact or  recitals  contained  in  this  Agreement  or in the
     certificates for Voting Shares or Common Shares or the Rights  Certificates
     (except  its  countersignature  thereof) or be required to verify the same,
     but all such  statements  and  recitals are and will be deemed to have been
     made by the Corporation only;

e.   the  Rights  Agent will not be under any  responsibility  in respect of the
     validity of this  Agreement or the  authorization,  execution  and delivery
     hereof (except the due authorization,  execution and delivery hereof by the
     Rights  Agent) or in respect of the  validity  or  execution  of any Common
     Share  certificate  or  Rights  Certificate  (except  its  countersignature
     thereof);  nor will it be responsible  for any breach by the Corporation of
     any  covenant or  condition  contained  in this  Agreement or in any Rights
     Certificate;   nor  will  it  be   responsible   for  any   change  in  the
     exercisability  of the Rights  (including the Rights becoming void pursuant
     to subsection  3.1(b)) or any  adjustment  required under the provisions of
     Section 2.3 or be responsible for the manner,  method or amount of any such
     adjustment or the ascertaining of the existence of facts that would require
     any such  adjustment  (except  with respect to the exercise of Rights after
     receipt of the certificate  contemplated by Section 2.3 describing any such
     adjustment);  nor  will it by any  act  hereunder  be  deemed  to make  any
     representation  or warranty as to the authorization of any Common Shares to
     be issued  pursuant  to this  Agreement  or any Rights or as to whether any
     Common Shares will, when issued, be duly and validly authorized,  executed,
     issued and delivered and fully paid and non-assessable;

f.   the  Corporation  agrees that it will  perform,  execute,  acknowledge  and
     deliver or cause to be performed, executed,  acknowledged and delivered all
     such further and other acts,  instruments  and assurances as may reasonably
     be required by the Rights Agent for the carrying out or  performing  by the
     Rights Agent of the provisions of this Agreement;

g.   the  Rights  Agent is hereby  authorized  and  directed  to accept  written
     instructions  with respect to the performance of its duties  hereunder from
     any person  believed by the Rights  Agent to be the  Chairman of the Board,
     President,  a Vice President or the Secretary or any Assistant Secretary of
     the Corporation, and to apply to such individual for advice or instructions
     in  connection  with its duties,  and it shall not be liable for any action
     taken or suffered by it in good faith in reliance upon  instructions of any
     such individual;


                                      -32-
<PAGE>
h.   the Rights Agent and any shareholder or stockholder,  director,  officer or
     employee of the Rights Agent may buy, sell or deal in Common Shares, Rights
     or other securities of the Corporation or become financially  interested in
     any  transaction in which the  Corporation  may be interested,  or contract
     with or lend money to the  Corporation or otherwise act as fully and freely
     as though it were not Rights  Agent under this  Agreement.  Nothing  herein
     shall  preclude the Rights Agent from acting in any other  capacity for the
     Corporation or for any other legal entity; and

i.   the  Rights  Agent may  execute  and  exercise  any of the rights or powers
     hereby  vested in it or perform any duty  hereunder  either itself or by or
     through  its  attorneys  or  agents,  and  the  Rights  Agent  will  not be
     answerable or accountable  for any act,  default,  neglect or misconduct of
     any such attorneys or agents or for any loss to the  Corporation  resulting
     from any such act, default, neglect or misconduct, provided reasonable care
     was exercised in the selection and continued employment thereof.

4.4  CHANGE OF RIGHTS AGENT

The  Rights  Agent  may  resign  and  be  discharged  from its duties under this
Agreement  upon  30  days' notice (or such lesser notice as is acceptable to the
Corporation)  in  writing  delivered  or  mailed  to the Corporation and to each
transfer  agent  of  Common  Shares  by  registered or certified mail and to the
holders of the Rights in accordance with Section 5.9. The Corporation may remove
the Rights Agent upon 30 days' notice in writing, mailed to the Rights Agent and
to  each transfer agent of the Common Shares by registered or certified mail and
to the holders of the Rights in accordance with Section 5.9. If the Rights Agent
should  resign  or  be  removed  or  otherwise  become  incapable of acting, the
Corporation  will  appoint  a  successor to the Right Agent.  If the Corporation
fails  to make such appointment within a period of 30 days after such removal or
after  it  has been notified in writing of such resignation or incapacity by the
resigning  or  incapacitated Rights Agent then the resigning Rights Agent or the
holder  of  any  Rights may apply to any court of competent jurisdiction for the
appointment  of  a  new  Rights  Agent.  Any  successor  Rights  Agent,  whether
appointed  by  the  Corporation  or  by  such  a  court,  shall be a corporation
incorporated  under the laws of Canada or a province thereof authorized to carry
on  the  business  of  a trust company.  After appointment, the successor Rights
Agent  will  be vested with the same powers, rights, duties and responsibilities
as  if it had been originally named as Rights Agent without further act or deed;
but  upon  payment  of  its outstanding fees and expenses the predecessor Rights
Agent  shall  deliver and transfer to the successor Rights Agent any property at
the  time  held  by it hereunder, and execute and deliver any further assurance,
conveyance, act or deed necessary for the purpose.  Not later than the effective
date  of  any  such  appointment,  the  Corporation  will file notice thereof in
writing  with the predecessor Rights Agent and each transfer agent of the Common
Shares  and  give notice to the holders of the Rights in accordance with Section
5.9.  Failure  to  give any notice provided for in this Section 4.4, however, or
any defect therein, shall not affect the legality or validity of the resignation
or removal of the Rights Agent or the appointment of the successor Rights Agent,
as  the  case  may  be.

                                   ARTICLE 5
                                 MISCELLANEOUS

5.1  REDEMPTION AND WAIVER

     a.   The Board of Directors acting in good faith may, at its option, at any
          time prior to the occurrence of a Flip-in  Event,  elect to redeem all
          but not less than all of the then  outstanding  Rights at a redemption
          price  of  $0.0001  per  Right  appropriately  adjusted  in  a  manner
          analogous to the applicable  adjustment provided for in Section 2.3 if
          an event of the  type  analogous  to any of the  events  described  in
          Section 2.3 shall have occurred  (such  redemption  price being herein
          referred to as the "Redemption  Price").  The redemption of the Rights
          by the Board of Directors may be made  effective at such time, on such
          basis and with such  conditions  as the Board of Directors in its sole
          discretion may establish.

     b.   If the Board of  Directors  elects or is  deemed  to have  elected  to
          redeem the Rights,  the right to exercise  the Rights will  thereupon,
          without  further  action and without  notice,  terminate  and the only
          right  thereafter  of the  holders of Rights  shall be to receive  the
          Redemption Price.

     c.   Within 10 days after the Board of  Directors  electing  or having been
          deemed to have  elected to redeem the Rights,  the  Corporation  shall
          give notice of  redemption  to the holders of the Rights in accordance
          with Section 5.9. Each such notice of redemption will state the method
          by which  the  payment  of the  Redemption  Price  will be  made.  The
          Corporation  may not redeem,  acquire or purchase for value any Rights
          at any time in any manner  other than that  specifically  set forth in
          this  Section  5.1 or other than in  connection  with the  purchase of
          Common Shares prior to the Separation Time.

     d.   The Board of Directors may prior to the  occurrence of a Flip-in Event
          determine, upon prior written notice to the Rights Agent, to waive the
          application of Section 3.1 to any particular Flip-in Event.

     e.   The Board of  Directors  may waive the  application  of Section 3.1 in
          respect  to the  occurrence  of any  Flip-in  Event  if the  Board  of
          Directors  has  determined  within ten Trading Days  following a Stock
          Acquisition   Date  that  a  Person  became  an  Acquiring  Person  by
          inadvertence and without any intention to become, or knowledge that it
          would become,  an Acquiring  Person under this  Agreement  and, in the
          event that such a waiver is granted  by the Board of  Directors,  such
          Stock Acquisition Date shall be deemed not to have occurred.  Any such
          waiver  pursuant to subsection  5.1(e) must be on the  condition  that
          such Person, within ten days after the foregoing  determination by the
          Board of  Directors  or such  earlier  or later  date as the  Board of
          Directors  may determine  (the  "Disposition  Date"),  has reduced its
          Beneficial  Ownership  of Voting  Shares  such  that the  Person is no
          longer an Acquiring  Person. If the Person remains an Acquiring Person
          at the close of business on the Disposition Date, the Disposition Date
          shall  be  deemed  to be the date of  occurrence  of a  further  Stock
          Acquisition Date and Section 3.1 shall apply thereto.

     f.   If a  Person  makes  a  Permitted  Bid or a  Competing  Permitted  Bid
          pursuant to which more than 50 per cent of the then outstanding Voting
          Shares  (other  than those  Voting  Shares  Beneficially  Owned by the
          Persons  making the Permitted Bid or the Competing  Permitted  Bid, at
          the date of the  Permitted  Bid or the  Competing  Permitted  Bid) are
          taken up and  paid for by such  Person,  then the  Board of  Directors
          shall, immediately upon the consummation of such acquisition,  without
          further  formality,  be deemed to have elected to redeem the Rights at
          the  Redemption  Price  on the  expiry  date of the  Permitted  Bid or
          Competing Permitted Bid, as the case may be.


                                      -34-
<PAGE>
     g.   Where  a  Take-over  Bid  that  is not a  Permitted  Bid or  Competing
          Permitted  Bid  is  withdrawn  or  otherwise   terminated   after  the
          Separation  Time has occurred and prior to the occurrence of a Flip-in
          Event,  the Board of Directors may elect to redeem all the outstanding
          Rights at the Redemption Price.

     h.   Upon the Rights being redeemed pursuant to subsection  5.1(g), all the
          provisions  of  this  Agreement  shall  continue  to  apply  as if the
          Separation Time had not occurred and Rights Certificates  representing
          the number of Rights held by each holder of record of Common Shares as
          of the Separation Time had not been mailed to each such holder and for
          all purposes of this  Agreement,  the Separation  Time shall be deemed
          not to have occurred.

5.2  EXPIRATION

No  Person  shall  have any rights whatsoever pursuant to or arising out of this
Agreement  or  in  respect  of  any  Right after the Expiration Time, except the
Rights  Agent  as  specified  in  subsections  4.1(a)  and  (b).

5.3  ISSUANCE OF NEW RIGHTS CERTIFICATES

Notwithstanding  any of the provisions of this Agreement or of the Rights to the
contrary,  the  Corporation  may,  at  its option, issue new Rights Certificates
evidencing  Rights  in such form as may be approved by the Board of Directors to
reflect  any  adjustment  or  change  in  the  number or kind or class of shares
purchasable  upon  exercise  of Rights made in accordance with the provisions of
this  Agreement.

5.4  SUPPLEMENTS AND AMENDMENTS

     a.   Without the  approval of any holders of Voting  Shares or Rights,  the
          Corporation  may make  amendments  to this  Agreement  to correct  any
          clerical or typographical  error or which are required to maintain the
          validity of the Agreement as a result of any change in any  applicable
          legislation or regulations  thereunder.  The Corporation may, prior to
          the date of the  shareholders'  meeting referred to in Section 5.4(f),
          supplement or amend this Agreement without the approval of any holders
          of  Rights or Voting  Shares  in order to make any  changes  which the
          Board  of  Directors  acting  in good  faith  may  deem  necessary  or
          desirable.  Notwithstanding  anything  in  this  Section  5.4  to  the
          contrary,  no supplement or amendment  shall be made to the provisions
          of Article 4 except with the written  concurrence  of the Rights Agent
          to such change, supplement or amendment.

     b.   Subject to  subsection  5.4(a),  the  Corporation  may, with the prior
          consent of the holders of Voting  Shares  obtained as set forth below,
          at any time before the Separation Time,  amend, vary or rescind any of
          the provisions of this  Agreement and the Rights  (whether or not such
          action would materially  adversely affect the interests of the holders
          of Rights generally).  Such consent shall be deemed to have been given
          if the action  requiring such approval is approved by the  affirmative
          vote of a  majority  of the  votes  cast by  Independent  Shareholders
          represented in person or by proxy at the Special Meeting.

     c.   The  Corporation  may, with the prior consent of the holders of Rights
          obtained as set forth below,  at any time after the Stock  Acquisition
          Date amend,  vary or rescind any of the  provisions of this  Agreement
          and the Rights (whether or not such action would materially  adversely
          affect the  interests  of the holders of Rights  generally),  provided
          that no such  amendment,  variation  or deletion  shall be made to the
          provisions  of Article 4 except  with the written  concurrence  of the
          Rights Agent thereto.  Such consent shall be deemed to have been given
          if  such  amendment,  variation  or  deletion  is  authorized  by  the
          affirmative  votes of the holders of Rights  present or represented at
          and entitled to vote at a meeting of the holders and  representing 50%
          plus one of the votes cast in respect thereof.

     d.   Any  approval  of the  holders of Rights  shall be deemed to have been
          given if the action  requiring  such  approval  is  authorized  by the
          affirmative  votes of the holders of Rights present or represented and
          entitled   to  vote  at  a  meeting  of  the  holders  of  Rights  and
          representing a majority of the votes cast in respect thereof.  For the
          purposes hereof,  each outstanding  Right (other than Rights which are
          void pursuant to the provisions hereof) shall be entitled to one vote,
          and the procedures for the calling, holding and conduct of the meeting
          shall be  those,  as  nearly  as may be,  which  are  provided  in the
          Corporation's  by-laws and the Business  Corporations Act with respect
          to meetings of shareholders of the Corporation.

     e.   Any amendments made by the  Corporation to this Agreement  pursuant to
          Subsection  5.4(a) which are required to maintain the validity of this
          Agreement as a result of any change in any  applicable  legislation or
          regulation thereunder shall:

          i.   if  made  before  the  Separation   Time,  be  submitted  to  the
               shareholders   of  the   Corporation   at  the  next  meeting  of
               shareholders and the shareholders  may, by the majority  referred
               to in subsection 5.4(b), confirm or reject such amendment;

          ii.  if made after the Separation Time, be submitted to the holders of
               Rights at a meeting  to be  called  for on a date not later  than
               immediately  following  the next meeting of  shareholders  of the
               Corporation  and the holders of Rights may, by resolution  passed
               by the  majority  referred to in  Subsection  5.4(d),  confirm or
               reject such amendment.

               Any  such  amendment  shall  be  effective  from  the date of the
               resolution  of the Board of Directors  adopting  such  amendment,
               until it is  confirmed  or  rejected  or until  it  ceases  to be
               effective and, where such amendment is confirmed, it continues in
               effect in the form so confirmed. If such amendment is rejected by
               the  shareholders or the holders of Rights or is not submitted to
               the  shareholders  or  holders of Rights as  required,  then such
               amendment  shall  cease  to  be  effective  from  and  after  the
               termination  of the meeting at which it was  rejected or to which
               it should have been but was not  submitted  or from and after the
               date of the  meeting of holders of Rights  that  should have been
               but was not held,  and no  subsequent  resolution of the Board of
               Directors  to amend  this  Agreement  to  substantially  the same
               effect shall be effective until confirmed by the  shareholders or
               holders of Rights, as the case may be.


                                      -36-
<PAGE>
     f.   In conjunction with the  Corporation's  next annual general meeting of
          shareholders,  the Board of  Directors  shall  call and hold a Special
          Meeting  of  holders  of Voting  Shares to  consider  and,  if thought
          appropriate,  ratify the distribution  and the continued  existence of
          the Rights.  The Special  Meeting shall be held on a date fixed by the
          Board of Directors,  which date shall be no later than that date which
          is one year after the date of this  Agreement.  The Board of Directors
          shall fix a record date for  determining  the holders of Voting Shares
          entitled to receive notice of the Special  Meeting in accordance  with
          all applicable  laws and the articles and by-laws of the  Corporation.
          Unless a majority  of the votes cast on such  resolution  are voted in
          favour of the  continued  existence  of the Rights,  then the Board of
          Directors shall  immediately  upon the confirmation by the Chairman of
          such  shareholders'  meeting  of  the  result  of  the  vote  on  such
          resolution,  without further  formality,  be deemed to have elected to
          redeem the Rights at the Redemption Price.

5.5  FRACTIONAL RIGHTS AND FRACTIONAL SHARES

     a.   The Corporation  shall not be required to issue fractions of Rights or
          to distribute Rights Certificates which evidence fractional Rights. In
          lieu of such fractional Rights,  there shall be paid to the registered
          holders  of  the  Rights   Certificates  with  regard  to  which  such
          fractional  Rights would otherwise be issuable an amount in cash equal
          to the same  fraction of the Market Price of a whole Right  determined
          on the  date  on  which  such  fractional  Right  would  otherwise  be
          issuable.

     b.   The  Corporation  shall not be required to issue  fractions  of Common
          Shares upon exercise of the Rights or to distribute certificates which
          evidence fractional Common Shares.  Fractions of Common Shares may, at
          the election of the Corporation, be evidenced by scrip certificates or
          in lieu of issuing fractional Common Shares, the Corporation shall pay
          to the  registered  holders of Rights  Certificates,  at the time such
          Rights are  exercised as herein  provided,  an amount in cash equal to
          the same  fraction of the Market Price of one Common Share at the date
          of such exercise.

5.6  RIGHTS OF ACTION

Subject  to the terms of this Agreement, all rights of action in respect of this
Agreement,  other  than  rights of action vested solely in the Rights Agent, are
vested  in  the  respective registered holders of the Rights; and any registered
holder  of  any  rights,  without  the  consent  of  the  Rights Agent or of the
registered  holder of any other Rights, may, on such holder's own behalf and for
such  holder's  own benefit and the benefit of other holders of rights, enforce,
and  may  institute  and  maintain  any  suit,  action or proceeding against the
Corporation  to  enforce such holder's right to exercise such holder's Rights in
the  manner  provided in such holder's Rights Certificate and in this Agreement.
Without  limiting  the  foregoing  or  any  remedies available to the holders of
Rights,  it  is  specifically  acknowledged that the holders of Rights would not
have  an  adequate  remedy  at  law for any breach of this Agreement and will be
entitled to specific performance of the obligations under, and injunctive relief
against actual or threatened violations of the obligations of any person subject
to,  this  Agreement.

5.7  REGULATORY APPROVALS

Any  obligation  of  the  Corporation  or  action  or event contemplated by this
Agreement  shall  be subject to the receipt of any requisite approval or consent
from  any  governmental  or  regulatory  authority, and, without limitation, all
necessary  approvals  of  The  Toronto  Stock Exchange shall be obtained, to the
issuance  of  Common Shares upon the exercise of Rights under subsection 2.2(d).

Notwithstanding  any  provision of this Agreement to the contrary, any amendment
to  this  Agreement  will be subject to the prior written consent of The Toronto
Stock  Exchange.

5.8  UNLAWFUL DISTRIBUTIONS


                                      -37-
<PAGE>
If  in  the  opinion  of the Board of Directors (who may rely upon the advice of
counsel)  any  action  or  event  contemplated  by  this Agreement would require
compliance by the Corporation with the securities laws or comparable legislation
of  a  jurisdiction  outside Canada, the Board of Directors acting in good faith
may  take such actions as it may deem appropriate to ensure that such compliance
is  not required, including, without limitation, establishing procedures for the
issuance  to  a  Canadian  resident  trustee of Rights or securities issuable on
exercise  of  Rights,  the  holding  thereof  in  trust for the Persons entitled
thereto  (but reserving to the trustee or to the trustee and the Corporation, as
the  Corporation  may  determine,  absolute  investment  discretion with respect
thereto)  and  the sale thereof and remittance of proceeds of such sale, if any,
to  the  Persons  entitled  thereto.  In  no  event shall the Corporation or the
Rights  Agent  be  required to issue or deliver Rights or securities issuable on
exercise  of  Rights  to Persons who are citizens, residents or nationals of any
jurisdiction  other  than  Canada,  in  which  such  issue  or delivery would be
unlawful  without  registration  of  the relevant Persons or securities for such
purposes.  Notwithstanding  the  foregoing,  to  the extent that the issuance or
delivery  of  the Rights or securities issuable on exercise of Rights to Persons
who  are citizens, residents or nationals of any such jurisdiction in which such
issue  or  delivery  would  be  so  unlawful, such Rights or securities shall be
issued and delivered to such Persons to the extent the same may be so issued and
delivered  in reliance upon applicable exemptions from registration requirements
in  such  jurisdictions.

                    [FORM  OF  RIGHTS  CERTIFICATE]

Certificate  No.                                              __________  Rights

THE  RIGHTS ARE SUBJECT TO TERMINATION ON THE TERMS SET FORTH IN THE SHAREHOLDER
RIGHTS PLAN AGREEMENT.  UNDER CERTAIN CIRCUMSTANCES (SPECIFIED IN SECTION 3.1(b)
OF  THE  SHAREHOLDER  RIGHTS  PLAN  AGREEMENT),  RIGHTS BENEFICIALLY OWNED BY AN
ACQUIRING  PERSON  OR  TRANSFEREES  OF  AN ACQUIRING PERSON OR ITS AFFILIATES OR
ASSOCIATES  (AS SUCH TERMS ARE DEFINED IN THE SHAREHOLDER RIGHTS PLAN AGREEMENT)
OR  ANY  PERSON  ACTING  JOINTLY OR IN CONCERT WITH ANY OF THEM MAY BECOME VOID.

                           RIGHTS  CERTIFICATE


This  certifies  that                       ,  or  registered  assigns,  is  the
                      ----------------------
registered  holder  of  the  number  of  Rights  set  forth above, each of which
entitles  the  registered  holder  thereof, subject to the terms, provisions and
conditions of the Shareholder Rights Plan Agreement, dated as of the 19th day of
May,  1999 (the "Rights Agreement") between Centurion Energy International Inc.,
a  corporation  amalgamated  under  the  Business  Corporations  Act  (the
"Corporation")  and Montreal Trust Company of Canada, a trust company, as rights
agent  (the "Rights Agent") (which term shall include any successor Rights Agent
under  the Rights Agreement), to purchase from the Corporation at any time after
the  Separation Time (as such term is defined in the Rights Agreement) and prior
to  the  Expiration  Time (as such term is defined in the Rights Agreement), one
fully  paid  common  share of the Corporation (a "Common Share") at the Exercise
Price  referred  to  below,  upon  presentation  and  surrender  of  this Rights
Certificate  together  with  the  Form of Election to Exercise duly executed and
submitted to the Rights Agent at its principal office in either of the cities of
Calgary  or  Toronto.  Until adjustment thereof in certain events as provided in
the  Rights  Agreement,  the  Exercise Price is equal to the greater of: (i) ten
($10.00)  dollars; and (ii) an amount equal to two (2) times the Market Price of
the  Common  Shares  determined on the last day of the preceding calendar month.

In certain circumstances described in the Rights Agreement, each Right evidenced
hereby  may  entitle  the  registered  holder  thereof  to  purchase  or receive
securities  of  an  entity  other  than the Corporation, assets, debt, equity or
other  securities or property or assets of the Corporation, or more or less than
one  Common  Share  (or  a  combination  thereof), all as provided in the Rights
Agreement.

The Rights Certificate is subject to all of the terms, provisions and conditions
of  the  Rights  Agreement  which  terms,  provisions  and conditions are hereby
incorporated  herein  by  reference  and made a part thereof and to which Rights
Agreement  reference  is  hereby  made  for  a  full  description of the rights,
limitations  of  rights,  obligations,  duties  and immunities thereunder of the
Rights  Agent,  the  Corporation  and  the  holders  of the Rights Certificates.
Copies  of  the  Rights  Agreement  are  on  file at the principal office of the
Corporation  and  are  available  upon  written  request.


                                      -42-
<PAGE>
The  Rights  Certificate,  with  or  without  other  Rights  Certificates,  upon
surrender at any of the offices of the Rights Agent designated for such purpose,
may  be  exchanged for another Rights Certificate or Rights Certificates of like
tenor  and  the  date  evidencing  an  aggregate  number  of Rights equal to the
aggregate  number  of  Rights  evidenced  by  the  Rights  Certificate or Rights
Certificates  surrendered.  If  this  Rights  Certificate  shall be exercised in
part, the registered holder shall be entitled to receive, upon surrender hereof,
another Rights Certificate or Rights Certificates for the number of whole Rights
not  exercised.  No fractional Common Shares will be issued upon the exercise of
any  Rights evidenced hereby, but in lieu thereof a cash payment will be made as
provided  in  the  Rights  Agreement.

Subject  to the provisions of the Rights Agreement, the Rights evidenced by this
Certificate  may be redeemed by the Corporation at a redemption price of $0.0001
per  Right, subject to adjustment in certain events, under certain circumstances
at  its  option.

No  holder  of  this  Rights  Certificate, as such, shall be entitled to vote or
receive dividends or be deemed for any purpose the holder of Common Shares or of
any other securities which may at any time be issuable upon the exercise hereof,
nor  shall  anything contained in the Rights Agreement or herein be construed to
confer  upon  the  holder hereof, as such, any of the rights of a shareholder of
the  Corporation  or any right to vote for the election of directors or upon any
matter  submitted to shareholders at any meeting thereof, or to give or withhold
consent  to  any  corporate  action,  or  to receive notice of meetings or other
actions  affecting shareholders (except as provided in the Rights Agreement), or
to  receive  dividends  or  subscription  rights, or otherwise, until the Rights
evidenced  by  this  Rights Certificate shall have been exercised as provided in
the  Rights  Agreement.

The Rights Certificate shall not be valid or obligatory for any purpose until it
shall  have  been  countersigned  by  the  Rights  Agent.

WITNESS  the  facsimile  signature of the proper officers of the Corporation and
its  corporate  seal.
