                                    THE OFFER

 .1       The Offer

(a)  Subject to the terms and conditions of this Agreement, Burlington shall
     mail to holders of Canadian Hunter Shares and Canadian Hunter Options as
     soon as practicable but in any event not later than 11:59 p.m. (Calgary
     time) on October 19, 2001, an offer to purchase all of the outstanding
     Canadian Hunter Shares (including the associated Rights) including any
     Canadian Hunter Shares which may become outstanding pursuant to the
     exercise of outstanding Canadian Hunter Options and pursuant to the
     exchange of outstanding Deferred Share Units, for a price of $53.00 in cash
     for each Canadian Hunter Share which offer shall be made in accordance with
     this Agreement, the Act and Securities Laws and be subject to the
     conditions set forth in Schedule A hereto (the "Offer", which term shall
     include any amendments to, or extensions of, such Offer, including, without
     limitation, increasing the consideration, removing or waiving any condition
     or extending the date by which Canadian Hunter Shares may be tendered).
     Burlington and Canadian Hunter shall cooperate in making on a timely basis
     any filings with respect to the Offer, including amendments thereafter on a
     timely basis as required by Securities Laws. The Offer shall be prepared in
     both the English and French languages and in accordance with this
     Agreement, the Act and Securities Laws. Burlington shall provide Canadian
     Hunter with a draft copy of the Offer Documents prior to mailing for its
     review and comment.

(b)  Burlington may make the Offer itself or through any direct or indirect
     subsidiary. In the event that a Burlington subsidiary makes or participates
     in the making of the Offer, the term "Burlington" as used herein shall
     include such subsidiary, other than in Article 5 where the term

<PAGE>
                                       6


     "Burlington" shall not include such subsidiary, but Burlington shall
     continue to be liable to Canadian Hunter, as principal obligor, for such
     subsidiary's obligations hereunder and for any default by such subsidiary
     in the performance of its obligations hereunder.

(c)  The Offer shall expire at the Initial Expiry Time, except that the Offer
     may be extended, at the sole discretion of Burlington, if the conditions
     thereto set forth in Schedule A hereto are not satisfied on the date and
     time at which the Offer expires and if Burlington determines, acting
     reasonably, that there is a reasonable prospect that the conditions of the
     Offer may not be satisfied prior to the Expiry Time. In addition, in the
     event that any appropriate regulatory approval is not obtained prior to the
     time the Offer is scheduled to terminate, unless such approval has been
     denied, Burlington agrees that it will extend the Offer for not less than
     two additional successive 10 day periods, if upon the expiry of any
     extension, the appropriate regulatory approval has not been obtained.

     In the event that at the Expiry Time, all conditions of the Offer contained
     in Schedule A hereto have been satisfied or waived other than the condition
     set forth in paragraph (g) of Schedule A, Burlington hereby agrees to
     extend the Offer for a period of time not less than 10 days past the Expiry
     Time. If the condition set forth in paragraph (g) of Schedule A is not
     satisfied at the end of the extended Offer period, Burlington shall have no
     further obligation to extend the Offer.

     Subject to the satisfaction or waiver of the conditions set forth in
     Schedule A hereto, Burlington shall within three Business Days accept for
     payment and pay for all Canadian Hunter Shares validly tendered (and not
     properly withdrawn) pursuant to the Offer. Each of Burlington and Canadian
     Hunter shall use all commercially reasonable efforts to consummate the
     Offer, subject to the terms and conditions thereof.

(d)  It is agreed that Burlington may, in its sole discretion, waive any term or
     condition of the Offer for its benefit provided that if Burlington takes up
     and pays for any Canadian Hunter Shares it shall acquire not less than the
     Minimum Required Shares. Burlington agrees that it shall not amend any term
     or condition of the Offer (which for greater certainty, does not include
     waiving, in whole or part, a condition of the Offer) in a manner that is
     materially adverse to the holders of Canadian Hunter Shares without the
     prior written consent of Canadian Hunter other than to: (i) comply with
     Section 2.1(c); (ii) extend the Offer, if, at the initial or extended date
     on which the Offer is scheduled to terminate, any of the conditions to the
     Offer shall not be satisfied or waived by Burlington, until such time as
     such conditions are satisfied or waived by Burlington; (iii) extend the
     Offer for any period required by any rule, regulation, interpretation or
     position of the Securities Authorities applicable to the Offer or any
     period required by applicable law; or (iv) comply with the legal
     obligations of Burlington with respect to any amendment, modification or
     change of the Offer.

     Notwithstanding and without limiting the foregoing, Burlington may at any
     time following the Initial Expiry Time, reduce the Minimum Condition to a
     percentage not less than 50% (exclusive of any Canadian Hunter Shares that
     Burlington owned prior to the date the Offering Documents are mailed) and
     shall, subject to the conditions of the Offer being satisfied or waived,
     take up and pay for all Canadian Hunter Shares validly deposited to the
     Offer, provided that, after Burlington reduces the Minimum Condition,
     Burlington extends the Offer by a 10 day period and agrees to extend the
     Offer for not less than two additional successive 10 day periods if, upon
     the expiry of any extension, the Minimum Condition has not been satisfied.
     Any agreement of Burlington referred to in the foregoing sentence shall
     continue after the Effective Time until such agreement shall have been
     performed or this Agreement is terminated.

     Burlington shall provide a draft of any proposed amendment, modification or
     change to the Offer to Canadian Hunter.

(e)  Burlington will instruct the depositary under the Offer to advise Canadian
     Hunter from time to time, not less frequently than every three Business
     Days until the day immediately prior to the Expiry Time and thereafter on
     an hourly basis, if requested by Canadian Hunter and in such


<PAGE>
                                       7


     manner as Canadian Hunter may reasonably request, as to the number of
     Canadian Hunter Shares that have been tendered (and not withdrawn) under
     the Offer.

(f)  Burlington's obligation to make the Offer as set forth in Section 2.1(a) is
     conditional upon the execution and delivery to Burlington, concurrently
     with the execution of this Agreement, of pre-tender agreements referred to
     in Section 2.2(b).

(g)  Notwithstanding any of the other terms of this Agreement, Burlington shall
     not be required to make the Offer if, on or before the date Burlington
     would otherwise be required to make the Offer under the terms of this
     Agreement:

     (i)  any of the representations or warranties of Canadian Hunter contained
          herein shall not be true and correct in all material respects or
          Canadian Hunter shall not have complied in all material respects with
          each of its covenants set out herein; or

     (ii) the Board of Directors of Canadian Hunter shall have withdrawn its
          positive recommendation of the Offer; or

     (iii) a Material Adverse Change shall have occurred, or a person shall have
          commenced a bona fide action for injunctive relief against the
          performance of this Agreement or the completion of the Offer, or
          another event shall have occurred or circumstances shall exist which
          would make it impossible or highly unlikely to satisfy one or more of
          the conditions of the Offer set forth in Schedule A hereto.

The foregoing conditions are for the sole benefit of Burlington and may be
waived by Burlington at any time.

 .2       Canadian Hunter Directors' Circular

(a)  Canadian Hunter hereby consents to the Offer as set forth in Section 2.1
     and confirms that its Board of Directors has resolved that it will
     recommend that holders of Canadian Hunter Shares accept the Offer, has
     approved the entering into of this Agreement and has received the opinion
     of its financial advisors that the consideration payable pursuant to the
     Offer is fair, from a financial point of view, to the holders of Canadian
     Hunter Shares and has resolved to unanimously recommend acceptance of the
     Offer by the holders of Canadian Hunter Shares, subject to Section 8.3.
     Canadian Hunter shall prepare and make available for mailing with the
     Offer, in both the English and French languages, sufficient copies of a
     directors' circular prepared in accordance with Securities Laws. The
     directors' circular will set forth (among other things) the recommendation
     of the Board of Directors of Canadian Hunter as described above. Canadian
     Hunter shall provide Burlington with a draft copy of the directors'
     circular prior to its finalization for Burlington's review and comment.

(b)  The Board of Directors of Canadian Hunter has been advised that the
     directors and officers of Canadian Hunter intend to tender their Canadian
     Hunter Shares under the Offer and have agreed to elect that, in lieu of
     exercising their Canadian Hunter Options, Canadian Hunter will pay the
     difference between the exercise price of their Canadian Hunter Options and
     the purchase price for the Canadian Hunter Shares under the Offer
     immediately after the Take-up Date in exchange for the termination of their
     Canadian Hunter Options and providing that such director or officer agrees
     to surrender any remaining unexercised options to Canadian Hunter for
     cancellation for no consideration effective immediately after the Take-up
     Date. Canadian Hunter represents that its director's and officer's have
     agreed to execute pre-tender agreements (in the form of the agreement
     attached hereto as Schedule B) and agrees to use its reasonable best
     efforts to deliver such agreements within 72 hours of the execution of this
     Agreement duly executed by all of its directors and officers. The
     directors' circular shall reflect the execution and delivery of such
     pre-tender agreements and the agreement of the directors and officers to
     tender their Canadian Hunter Shares pursuant to the Offer.

(c)  Canadian Hunter represents that it has obtained advice from CIBC World
     Markets Inc. and Goldman Sachs & Co. that the consideration to be offered
     to Canadian Hunter's shareholders pursuant to the Offer is fair to holders
     of Canadian Hunter Shares from a financial point of view and that such
     financial advisor will each provide a written opinion to such effect on or
     before October 19, 2001. The fairness opinions will be attached to or
     referred to in the directors' circular referred to in Section 2.2(a).

 .3       Offer Documents

(a)  Burlington shall file or cause to be filed with the appropriate Securities
     Authorities an Offer to Purchase and Take-over Bid Circular and the related
     Letter of Transmittal and Notice of Guaranteed Delivery pursuant to which
     the Offer will be made (collectively, the "Offer Documents"). The Offer
     Documents, when filed with the Securities Authorities and when mailed to
     holders of Canadian Hunter Shares, shall contain (or shall be amended in a
     timely manner to contain) all information which is required to be included
     therein in accordance with the Act and any applicable Canadian provincial
     securities laws, United States securities laws, the "blue sky" or
     securities laws of the states of the United States and any other applicable
     law (collectively, the "Securities Laws").

(b)  Canadian Hunter agrees to provide such assistance as Burlington or its
     agents may reasonably request in connection with communicating the Offer
     and any amendments and supplements thereto to the holders of the Canadian
     Hunter Shares and to such other persons as are entitled to receive the
     Offer under Securities Laws, including providing lists and updated or
     supplemental lists of the holders of Canadian Hunter Shares, holders of
     Canadian Hunter Options and holders of Deferred Share Units and other
     securities convertible into or exchangeable for Canadian Hunter Shares and
     mailing labels with respect to all such holders of securities as soon as
     possible after the date of this Agreement but in any event no later than
     the close of business in Calgary on October 11, 2001 and updates or
     supplements thereto from time to time as may be requested by Burlington.

 .4       Outstanding Stock Options and Deferred Share Units

(a)  Subject to the receipt of any necessary regulatory approvals, persons
     holding options pursuant to the Stock Option Plan who may do so under
     Securities Laws and in accordance with the Stock Option Plan shall be
     entitled to exercise all of their options and tender all Canadian Hunter
     Shares issued in connection therewith under the Offer upon payment by
     certified cheque or bank draft of the exercise price in full. The Canadian
     Hunter Board of Directors shall not, prior to completion of the Offer,
     grant additional options pursuant to the Stock Option Plan. It is agreed by
     Burlington that all Canadian Hunter Options which have been tendered to
     Canadian Hunter for exercise, conditional on Burlington taking up Canadian
     Hunter Shares under the Offer ("Conditional Option Exercise"), shall be
     deemed to have been exercised concurrently with the take-up of Canadian
     Hunter Shares by Burlington. Furthermore, Burlington shall accept as
     validly tendered under the Offer as of the Take-up Date all Canadian Hunter
     Shares which are to be issued pursuant to the Conditional Option Exercise,
     provided that the holders of such options indicate that such shares are
     tendered pursuant to the Offer and provided that such holder agrees to
     surrender their remaining unexercised options to Canadian Hunter for
     cancellation for no consideration effective immediately after the Take-up
     Date.

(b)  Canadian Hunter and Burlington agree that to the extent holders of Canadian
     Hunter Options do not exercise such Canadian Hunter Options and tender the
     Canadian Hunter Shares they receive upon such exercise, Canadian Hunter may
     agree with all remaining holders of Canadian Hunter Options that, in lieu
     of such persons exercising their Canadian Hunter Options, Canadian Hunter
     will pay to such persons the difference between the exercise price of their
     Canadian Hunter Options and the purchase price for the Canadian Hunter
     Shares under the Offer immediately after the Take-up Date of the Offer in
     exchange for the termination of their Canadian Hunter Options and provided
     that such holders agree to surrender their remaining unexercised options to

<PAGE>
                                       9


     Canadian Hunter for cancellation for no consideration effective immediately
     after the Take-up Date.

(c)  Persons holding Deferred Share Units shall be entitled to exchange all of
     their Deferred Share Units for Canadian Hunter Shares and tender all
     Canadian Hunter Shares issued in connection therewith to the Offer.

(d)  Burlington and Canadian Hunter acknowledge and agree that, pursuant to the
     Stock Option Plan and Deferred Share Unit Plan, all outstanding and
     unvested Canadian Hunter Options and all outstanding Deferred Share Units,
     respectively, shall immediately vest at the Effective Time.

 .5       Rights Plan

(a)  Canadian Hunter represents to Burlington that its Board of Directors has
     irrevocably resolved to waive the application of the Rights Plan to the
     Offer immediately prior to the Expiry Time and to any other actions taken
     by Burlington in furtherance of acquiring all of the Canadian Hunter Shares
     and covenants to Burlington to take all action necessary pursuant to the
     Rights Plan to effect such waiver no earlier than the Expiry Time, and to
     ensure that the Separation Time (as defined in the Rights Plan) does not
     occur.

(b)  Canadian Hunter covenants and agrees with Burlington and represents to
     Burlington that its Board of Directors has resolved not to waive the
     application of the Rights Plan or to redeem any of the outstanding Rights
     or take any other action which would limit the application of the Rights
     Plan to any transaction other than a Take-over Proposal that expires no
     sooner than the Initial Expiry Time.

 .6       Employee Plans

(a)  Canadian Hunter shall terminate the Employee Share Savings Plan and the
     Share Purchase Plan subject to and coincident with the first take-up of
     Canadian Hunter Shares by Burlington under the Offer on the Take-up Date
     and shall make whatever arrangements may be necessary to permit the
     participants in such plans to tender the Canadian Hunter Shares allocated,
     or to be allocated, as the case may be, to them on termination of such
     plans under the Offer. Burlington and Canadian Hunter acknowledge and agree
     that, pursuant to the Share Purchase Plan, all outstanding loans between
     Canadian Hunter and a Participant (as defined in such plan) shall be due
     and payable on the Take-up Date and that all outstanding amounts shall be
     netted against any amounts due from Burlington under the Offer to the
     Participants (as defined in such Plan).

(b)  Subject to and following the take-up of Canadian Hunter Shares by
     Burlington under the Offer on the Take-up Date, Burlington covenants and
     agrees that, effective upon the termination of the Employee Share Savings
     Plan pursuant to Section 2.6(a) and up to and including the date (the
     "Rollover Date") which is the earlier of (i) the date that such participant
     is covered under Burlington's stock purchase savings plan and (ii) December
     31, 2001, Burlington shall cause Canadian Hunter to make all necessary
     arrangements so that all participants in such plan prior to the Take-up
     Date shall continue to have the same payroll amounts withheld by Canadian
     Hunter. On the Rollover Date, Burlington shall cause Canadian Hunter to pay
     all such accumulated contributions to such participants together with an
     amount equal to (i) in the case of participants who continue to be employed
     by Canadian Hunter on the Rollover Date, the actual contributions made by
     such participants up to and including the Rollover Date and (ii) in the
     case of participants who are terminated on or prior to the Rollover Date,
     the maximum amount such participants could have contributed under the
     Employee Share Savings Plan up to and including the Rollover Date had they
     not been terminated, provided, however, where a participant has been
     terminated for just cause, Canadian Hunter shall only be required to pay an
     amount equal to such participant's actual contributions.

     accordance with Canadian Hunter's customary year end bonus practices
     consistently applied in accordance with prior years (the "Canadian Hunter

     bonus amounts for December 31, 2001 to be paid to the eight officers of

     to such employees for the December 31, 2000 calendar year.

is held, shall not contain any untrue statement of a material fact or omit to
state a material fact required to be stated therein or necessary to make the
statements therein, in light of the circumstances under which they are made, not
misleading and will comply in all material respects with all applicable
requirements of law. Burlington and Canadian Hunter each agree to correct
promptly any such information provided by it for use in any Information Circular
which shall have become false or misleading.

     Hunter's independent accountants or (ii) in the case of unaudited interim
     financial statements, to the extent they may not include footnotes or may
     be condensed or summary statements), and fairly present the consolidated
     financial position, results of operations and changes in financial position
     of Canadian Hunter and its consolidated subsidiaries as of the dates
     thereof and for the periods indicated therein (subject, in the case of any
     unaudited interim financial statements, to normal year-end audit
     adjustments).

(b)  Canadian Hunter will deliver to Burlington as soon as they become available
     true and complete copies of any report or statement filed by it with
     Securities Authorities subsequent to the date hereof. As of their
     respective dates, such reports and statements (excluding any information
     therein provided by Burlington, as to which Canadian Hunter makes no
     representation) will not contain any untrue statement of a material fact or
     omit to state a material fact required to be stated therein or necessary to
     make the statements therein, in light of the circumstances under which they
     are made, not misleading and will comply in all material respects with all
     applicable requirements of law. The consolidated financial statements of
     Canadian Hunter issued by Canadian Hunter or to be included in such reports
     and statements (excluding any information therein provided by Burlington,
     as to which Canadian Hunter makes no representation) will be prepared in
     accordance with Canadian GAAP (except (i) as otherwise indicated in such
     financial statements and the notes thereto or, in the case of audited
     statements, in the related report of Canadian Hunter's independent
     accountants or (ii) in the case of unaudited interim financial statements,
     to the extent they may not include footnotes or may be condensed or summary
     statements) and will present fairly the consolidated financial position,
     results of operations and changes in financial position of Canadian Hunter
     as of the dates thereof and for the periods indicated therein (subject, in
     the case of any unaudited interim financial statements, to normal year-end
     audit adjustments).

to properly evaluate the Take-over Proposal and accordingly is reaffirming and
maintaining its recommendation of the Offer pending receipt and analysis of
additional information shall not constitute an event within the ambit of Section
8.2(b) hereof or trigger any obligations to make the payment contemplated by
this Section, provided that the Board of Directors of Canadian Hunter, not less
than five days before the Expiry Time of the Offer, publicly reaffirms and
maintains its recommendation of the Offer as set forth in Section 2.2(a) to
holders of Canadian Hunter Shares without the foregoing qualification in respect
of receipt and analysis of additional information relating to the Take-over
Proposal.

 .3       No Solicitation

     Canadian Hunter shall immediately cease and cause to be terminated any
existing solicitation, initiation, encouragement, activity, discussion or
negotiation with any parties conducted heretofore by Canadian Hunter, any of its
subsidiaries or their officers, directors, employees, financial advisors,
representatives and agents ("Representatives") with respect to a Take-over
Proposal (as defined herein) whether or not initiated by Canadian Hunter and in
connection therewith, Canadian Hunter shall not release any third party from any
confidentiality or standstill agreement to which Canadian Hunter and such third
party is a party or amend any of the foregoing and shall exercise all rights to
require the return of information regarding Canadian Hunter. From and after the
date hereof, Canadian Hunter and its subsidiaries will not, and will not
authorize or permit any of their Representatives to, directly or indirectly,
solicit, initiate or encourage (including by way of furnishing information) or
participate in or take any other action to facilitate any inquiries or the
making of any proposal which constitutes or may reasonably be expected to lead
to a Take-over Proposal from any person, or engage in any discussion,
negotiations or inquiries relating thereto or accept any Take-over Proposal;
provided, however, that Canadian Hunter may: (i) engage in discussions or
negotiations with a third party who (without any solicitation, initiation or
encouragement, directly or indirectly, by Canadian Hunter, any of its
subsidiaries or the Representatives after the date hereof) seeks to initiate
such discussions or negotiations and may furnish such third party information
concerning Canadian Hunter and its business, properties

                                       23


and assets which has previously been provided to Burlington if, and only to the
extent that: (A) the third party has first made a bona fide written Take-over
Proposal that is financially superior to the Offer (as determined in good faith
in each case by Canadian Hunter's Board of Directors after receiving the advice
of its financial advisors) (a "Superior Proposal") and Canadian Hunter's Board
of Directors has concluded in good faith, after considering applicable law and
receiving the advice of outside counsel that such action is required by the
Canadian Hunter Board of Directors to comply with fiduciary duties under
applicable law; (B) prior to furnishing such information to or entering into
discussions or negotiations with such person or entity, Canadian Hunter receives
from such person or entity an executed confidentiality agreement having
confidentiality and standstill terms substantially similar to those contained in
the Confidentiality Agreement; (C) Canadian Hunter immediately provides to
Burlington any information provided to any such person or entity if not
previously provided to Burlington; (ii) comply with applicable Securities Laws
relating to the provision of directors' circulars, and make appropriate
disclosure with respect thereto to Canadian Hunter's shareholders; and (iii)
accept, recommend, approve or implement a Superior Proposal contemplated in
clause (i)(A), but only (in the case of this clause (iii)) if prior to such
acceptance, recommendation, approval or implementation, Canadian Hunter's Board
of Directors shall have concluded in good faith, after considering provisions of
applicable law and after giving effect to all proposals to adjust the terms and
conditions of this Agreement and the Offer which may be offered by Burlington
during the 24 hour notice period set forth below Canadian Hunter terminates this
Agreement in accordance with Sections 8.2 and 11.1(f) and concurrently therewith
has paid the fees payable thereunder. Canadian Hunter shall give Burlington
orally and in writing at least 24 hours advance notice of any decision by the
Board of Canadian Hunter to accept, recommend, approve or implement a Superior
Proposal. Such notice shall include the principal business terms and conditions

their stead. Canadian Hunter shall, in accordance with the foregoing and subject
to the provisions of the Act, assist Burlington to secure the resignations of
all Canadian Hunter directors to be effective at such time as may be required by
Burlington and to use its best efforts to cause the election of the Burlington
nominees to fill the vacancies so created in order to effect the foregoing
without the necessity of a shareholder meeting.

 .5       Structure of Transaction

     Canadian Hunter shall, to the extent reasonable, cooperate with Burlington
in structuring the acquisition by Burlington of Canadian Hunter in a tax
efficient manner, including without limitation, by completing to the
satisfaction of Burlington, acting reasonably, a possible internal corporate
reorganization of Canadian Hunter involving the transfer of certain assets to
one or more partnerships and/or the transfer of certain assets or unincorporated
business divisions to separate wholly-owned Canadian subsidiary corporations.

with the foregoing.

their name in connection with any disclosure by Burlington of such financial
statements. Burlington agrees to reimburse Canadian Hunter for its reasonable
third party expenses in connection with complying with this Section 8.6.

     obtained or occurred on terms and conditions satisfactory to the Offeror,
     acting reasonably, and all applicable statutory or regulatory waiting
     periods shall have expired or been terminated;

(c)  no act, action, suit, proceeding, objection or opposition shall have been
     threatened or taken before or by any domestic or foreign court or tribunal

          by, or the sale to, the Offeror of the Canadian Hunter Shares or the
          right of the Offeror to own or exercise full rights of ownership of

                          FORM OF PRE-TENDER AGREEMENT

                                                                 October 8, 2001

Dear Sir:

Re:      Offer by Burlington to Purchase all of the Canadian Hunter Shares
--------------------------------------------------------------------------------

     Reference is made to the Pre-Acquisition Agreement dated October 8, 2001
(the "Pre-Acquisition Agreement") between Burlington and Canadian Hunter
pursuant to which Burlington has agreed to make an offer to purchase all of the
issued and outstanding Canadian Hunter Shares. Unless otherwise defined herein,
all capitalized terms referred to herein shall have the meanings attributed
thereto in the Pre-Acquisition Agreement.

     We understand that you (the "Selling Shareholder") or your affiliates
beneficially own, directly or indirectly, or exercise control or direction over,
the number of Canadian Hunter Shares set forth in your acceptance at the end of
this letter agreement.

     Any references in this letter agreement to Canadian Hunter Shares owned by
the Selling Shareholder shall mean such number of Canadian Hunter Shares and,
where the context requires, shall include all Canadian Hunter Shares issued to
the Selling Shareholder after the date hereof pursuant to the exercise of
Canadian Hunter Options.

     This letter agreement sets out the terms and conditions upon which the
Selling Shareholder has agreed, among other things, to support the Offer and to
deposit under the Offer, or cause to be deposited under the Offer, all of the
Canadian Hunter Shares (including Canadian Hunter Shares issuable upon the
exercise of Canadian Hunter Options) held by the Selling Shareholder that are,
or will be, beneficially owned or controlled by the Selling Shareholder.

1.   Covenants of Selling Shareholder

     By the acceptance of this letter agreement, the Selling Shareholder hereby
agrees, subject to the terms of paragraph 3 of this letter agreement, from the
date hereof until the earlier of the termination of this letter agreement and
the Take-up Date:

(a)  not to sell, assign, convey or otherwise dispose of any of the Canadian
     Hunter Shares owned by such Selling Shareholder and not to permit any
     affiliate of such Selling Shareholder to sell, assign, convey or otherwise
     dispose of any of the Canadian Hunter Shares owned by it;

(b)  unconditionally and irrevocably to accept and to cause any affiliate of
     such Selling Shareholder to unconditionally and irrevocably accept the
     Offer made by Burlington by depositing the Canadian Hunter Shares presently
     owned or hereafter acquired (including any Canadian Hunter Shares hereafter
     acquired pursuant to the exercise of any options to purchase Canadian
     Hunter Shares) by such Selling Shareholder or affiliate prior to the Expiry
     Time and in accordance with the terms and conditions of the Offer;

(c)  that they will not exercise any Canadian Hunter Options and that they agree
     to elect that, in lieu of exercising their Canadian Hunter Options,
     Canadian Hunter will pay the difference between the exercise price of their
     Canadian Hunter Options and the purchase price for the Canadian Hunter
     Shares under the Offer immediately after the Take-up Date in exchange for
     the termination of their Canadian Hunter Options and provided the Selling
     Shareholder agrees to surrender their remaining unexercised options to
     Canadian Hunter for cancellation for no consideration effective immediately
     after the Take-up Date;


<PAGE>
                                        2


(d)  that all loans made by Canadian Hunter to the Selling Shareholder shall be
     repaid in full on the Take-up Date and that all outstanding amounts shall
     be netted against any amounts due from Burlington under the Offer to the
     Selling Shareholder;

(e)  not to exercise any statutory or other rights of withdrawal with respect to
     any Canadian Hunter Shares owned by such Selling Shareholder or any
     affiliate of such Selling Shareholder once deposited pursuant to the Offer
     unless this letter agreement is terminated prior to Burlington taking up
     the Canadian Hunter Shares under the Offer; and

(f)  not to exercise any shareholder rights or remedies available at common law
     or pursuant to the Business Corporations Act (Alberta) or applicable
     securities legislation to delay, hinder, upset or challenge the Offer.

2.   Covenants of Burlington

(a)  Burlington shall make the Offer in accordance with the terms and conditions
     of the Pre-Acquisition Agreement and shall comply with the terms and
     conditions of Article 2 and Sections 12.3 and 12.4 thereof in respect of
     the Offer.

(b)  Burlington shall, subject to the satisfaction or waiver of the conditions
     set forth in the Offer, take up and pay for all Canadian Hunter Shares
     owned by the Selling Shareholder or any affiliate of the Selling
     Shareholder deposited pursuant to the Offer, all in accordance with the
     terms and conditions of the Offer and the provisions of the Pre-Acquisition
     Agreement.

officer required to be taken in the discharge of his fiduciary duties as a
director or officer of Canadian Hunter.

4.   Expenses

     Burlington and the Selling Shareholder agree to pay their own respective
expenses incurred in connection with this letter agreement. Each of the parties
hereto agrees to indemnify the other against any claim for a finder's fee or
other compensation validly made by any broker which has an agreement with such
indemnifying party for the payment of such fee or compensation. This paragraph 4
shall survive the termination of this letter agreement pursuant to paragraph 5.

5.   Termination

     It is understood and agreed that the respective rights and obligations
hereunder of Burlington and the Selling Shareholder shall cease and this letter
agreement shall terminate:

(a)  if, prior to the expiry of the Offer, another bona fide Take-over Proposal
     is announced, proposed, offered or made to the holders of Canadian Hunter
     Shares or Canadian Hunter which, in the opinion of Canadian Hunter's Board
     of Directors after consultation with its financial advisors, would
     constitute a Superior Proposal and which permits the Board of Directors of
     Canadian Hunter to withdraw, modify or change any recommendation regarding
     the Offer in accordance with Section 2.2(a) of the Pre-Acquisition
     Agreement; or

(b)  if the Canadian Hunter Board of Directors otherwise withdraws, modifies or
     changes any recommendation with respect to the Offer; or

(c)  if Burlington waives the Minimum Condition, decreases the consideration
     offered pursuant to the Offer or otherwise modifies or amends the Offer in
     a manner materially adverse to holders of Canadian Hunter Shares, provided
     that an extension of the Offer shall not constitute an adverse modification
     or amendment to the Offer; or


<PAGE>
                                        3


(d)  in the event that the Pre-Acquisition Agreement is terminated pursuant to
     Section 11.1 thereof.

     In the event of termination of this letter agreement, the Selling
Shareholder may withdraw all of the Canadian Hunter Shares deposited in
accordance with the terms and conditions of the Offer, this letter agreement
shall forthwith be of no further force and effect and there shall be no
obligation or liability on the part of either the Selling Shareholder or
Burlington, except as set forth in paragraph 4 and this paragraph 5 which
provisions shall survive the termination of this letter agreement. Nothing
herein shall relieve any party from liability for any breach of this letter
agreement.

whole of the agreement between the parties and may not be modified, amended,
altered or supplemented except upon the execution and delivery of a written

of this letter, none of the parties hereto shall disclose the existence of this
letter agreement, or any details hereof, to any person other than Canadian
Hunter, its directors and officers, without the prior written consent of the
other parties hereto, except to the extent required by law. The existence and
terms and conditions of this letter agreement may be disclosed by Burlington and
Canadian Hunter in the press release issued in connection with the execution of
the Pre-Acquisition Agreement and the Offer Documents and the Directors Circular

9.   Enurement

Burlington, the Selling Shareholder and their respective executors,
administrators, successors and permitted assigns.
