less than 66 2/3% of the votes cast. The Assure Board of Directors has agreed
that it will not solicit or initiate discussion or negotiations involving any
third party for any business combination involving Assure. GEOCAN has agreed to
pay Assure a non-completion fee of CDN$1 million, and Assure has agreed to pay

Assure also announces that it has mailed an information circular to Assure
securityholders in connection with the Arrangement.

                               ASSURE ENERGY INC.

August 5, 2005

TO:   Holders (the "Assure Securityholders") of common shares ("Assure Shares"),
      preferred  shares  ("Assure  Preferred  Shares")  and warrants to purchase
      Assure Shares ("Assure Warrants") of Assure Energy, Inc. ("Assure").

You are invited to attend a special meeting (the "Meeting") of Assure
Securityholders to be held at the offices of Bennett Jones LLP, 4500, 855-2nd
Street S.W., Calgary, Alberta at 10:00 a.m. on Wednesday, September 7, 2005 for
the purposes set forth in the accompanying Notice of Special Meeting of Assure
Securityholders. Capitalized terms not defined herein shall have the meaning
ascribed thereto in the information circular attached hereto.

At the Meeting, Assure Securityholders will be asked to consider and vote upon
an arrangement (the "Arrangement") under the provisions of the Business
Corporations Act (Alberta) (the "ABCA") involving Assure, Assure Securityholders
and GEOCAN Energy Inc. ("GEOCAN"). Pursuant to the Arrangement, the following
transactions will occur in the following order:

(1)   all of the issued and outstanding  Assure Shares,  Assure Preferred Shares
      and Assure Warrants held by Dissenting Securityholders as of the Effective
      Time shall be deemed to have been  transferred to Assure and cancelled and
      shall cease to be issued and  outstanding  and, as of the Effective  Time,
      such Dissenting  Securityholders  shall cease to have any rights as Assure
      Securityholders,  other  than the right to be paid the fair value of their
      Assure Shares, Assure Preferred Shares or Assure Warrants, as the case may
      be, and the names of such Dissenting Securityholders shall be removed from
      the  register of holders of Assure  Shares,  Assure  Preferred  Shares and
      Assure Warrants, as applicable; and

(2)   all of the issued and  outstanding  Assure  Shares  beneficially  owned by
      Assure  Shareholders at the Effective Time shall be transferred to GEOCAN,
      solely in exchange for the issue by GEOCAN, to such Assure Shareholders in
      respect of such Assure  Shares,  of fully paid and  non-assessable  common
      shares of GEOCAN  ("GEOCAN  Shares") on the basis of 0.7 of a GEOCAN Share
      for each Assure Share.

No fractional GEOCAN Shares will be issued. In the event that the conversions
contemplated by the Arrangement would result in an Assure Shareholder being
entitled to a fractional GEOCAN Share, the number of GEOCAN Shares to be issued
to each such former Assure Shareholder will be rounded up to the next whole
number of GEOCAN Shares. In calculating such fractional interests, all Assure
Shares held by a registered Assure Shareholder prior to the Effective Time will
be aggregated.

For the Arrangement to proceed, it must be approved by at least 66 2/3% of all
of the votes cast by holders of Assure Shares, Assure Preferred Shares and
Assure Warrants, voting together as a class, present in person or by proxy, at
the Meeting, such that (i) each Assure Shareholder shall be entitled to one vote
for each Assure Share held, (ii) each Assure Preferred Shareholder shall be
entitled to one vote for each Assure Preferred Share held, and (iii) each Assure
Warrantholder shall be entitled to one vote for each Assure Share such holder
would be entitled to receive upon the exercise of such Assure Warrants. If such
approval is obtained and if other conditions to the Arrangement becoming
effective are satisfied or waived, it is expected that the Arrangement will be
completed on or about the date of the Meeting.

If the requisite shareholder and regulatory approvals are obtained, an order of
the Court of Queen's Bench of Alberta approving the Arrangement will be sought
following the Meeting.


The Assure Board recommends that you vote in favour of the Arrangement.

The accompanying Information Circular provides a detailed description of the
Arrangement, Assure, GEOCAN and the matters to come before the Meeting. Please
give this material your careful consideration, and, if you require assistance,
consult your financial, income tax or other professional advisor.

To be represented at the Meeting, you must either attend the Meeting in person
or complete and sign the enclosed Form of Proxy and forward it so as to reach,
or be deposited with, Continental Stock Transfer & Trust Company
("Continental"), 17 Battery Place, New York, NY 10004, not later than

            Special Meeting of Securityholders of Assure Energy, Inc.
                   to be held on Wednesday, September 7, 2005

                                  INTRODUCTION

This Information Circular is furnished in connection with the solicitation of
proxies by and on behalf of the management of Assure Energy, Inc. for use at the
Meeting and any adjournments thereof. No Person has been authorized to give any
information or make any representation in connection with the Arrangement or
other matters to be considered at the Meeting other than those contained in this
Information Circular and, if given or made, any such information or
representation must not be relied upon as having been authorized. This
Information Circular does not constitute an offer to sell securities, a
solicitation of an offer to purchase securities or the solicitation of a proxy
by any Person in any jurisdiction in which such an offer or solicitation is not
authorized or in which the Person making such offer or solicitation is not
qualified to do so or to any Person to whom it is unlawful to make such an offer
or solicitation of an offer or proxy solicitation. Neither delivery of this
Information Circular nor any distribution of the securities referred to in this
Information Circular shall, under any circumstance, create an implication that
there has been no change in the information set forth therein since the date of
this Information Circular.

All summaries of, and reference to, the Arrangement in this Information Circular
are qualified in their entirety by reference to the complete text of the
Arrangement Agreement and the Plan of Arrangement, copies of which are attached
as Appendix B and Exhibit 1 to Appendix B respectively, to this Information
Circular. You are urged to carefully read the full text of the Arrangement
Agreement and the Plan of Arrangement.

All capitalized terms in this Information Circular but not otherwise defined
herein have the meanings set forth under "Glossary of Terms". Information
contained in this Information Circular is given as of August 5, 2005 unless
otherwise specifically stated.

                   INFORMATION FOR UNITED STATES SHAREHOLDERS

Assure Securityholders in the United States should be aware that such
requirements are different from those of the United States applicable to
registration statements under the U.S. Securities Act and proxy statements under
the U.S. Exchange Act. The financial statements for Assure and certain pro-forma
and historical financial information included herein have been prepared in
accordance with Canadian generally accepted accounting principles, which differ
from United States generally accepted accounting principles in certain material
respects, and thus are not comparable in all respects to financial statements
and pro-forma and historical financial information of United States companies.
Likewise, information concerning oil and gas properties, reserves and operations
of GEOCAN and Assure has been prepared in accordance with Canadian disclosure
standards and is not comparable in all respects to similar information for
United States companies.

The GEOCAN Shares to be issued pursuant to the Arrangement have not been and
will not be registered under the U.S. Securities Act and are being issued in
reliance on the exemption from registration set forth in Section 3(a)(l0)
thereof. The U.S. Securities Act imposes limitations on the resale of GEOCAN
Shares issued pursuant to the Arrangement to persons who were "affiliates" of
GEOCAN or Assure before the Arrangement or of GEOCAN after the Arrangement. See
"Part II -- The Arrangement -- Other Matters -- Resale of GEOCAN Shares --
United States" in this Information Circular.

                                     - 1 -

Assure Securityholders should be aware that the Arrangement and the ownership of
securities of GEOCAN and Assure may have material tax consequences in the United
States that are not described in this Information Circular which may include,
without limitation, the possibility that the Arrangement is a taxable
transaction, in whole or in part, for United States federal income tax purposes,
and the possibility that either Assure or GEOCAN may be classified as a passive
foreign investment company, which classification would subject holders to
special, generally adverse tax consequences.

Assure Securityholders resident in the United States are advised to consult
their own tax advisors to determine the particular tax consequences to them of
the Arrangement in light of their particular situation, as well as any tax
consequences that may arise under the laws of any other relevant foreign, state,
local, or other taxing jurisdiction.

Enforcement by Assure Securityholders of civil liabilities under United States
securities laws may be affected adversely by the fact that GEOCAN and Assure are
      organized under the laws of a jurisdiction outside the United States, that
some or all of their officers and directors are residents of countries other
than the
United States, that some of the experts named in this Information Circular are
residents of countries other than the United States, and that all or a
substantial portion of the assets of GEOCAN and Assure and such persons may be
located outside the United States.

The GEOCAN Shares to be issued in connection with the Arrangement have not been
approved or disapproved by the SEC or securities regulatory authorities of any
state of the United States, nor has the SEC or the securities regulatory
authorities of any state of the United States passed on the adequacy or accuracy
of this Information Circular. Any representation to the contrary is a criminal
offence.

                                     - 2 -

CAUTIONARY STATEMENT CONCERNING FORWARD-LOOKING STATEMENTS

This Information Circular, including all Appendices attached hereto and all
documents incorporated by reference herein, contains forward-looking statements.
All statements other than statements of historical fact contained in this
Information Circular are forward-looking statements, including, without
limitation, statements regarding Assure's or GEOCAN's future financial position,
business strategy, proposed acquisitions, budgets, litigation, project costs and
plans and objectives of management for future operations. Many of these
statements can be identified by looking for words such as "believe," "expects,"
"will," "intends," "projects," "anticipates," "estimates," "continues" or
similar words or the negative thereof. Assure, and, where applicable, GEOCAN,
cannot assure you that the plans, intentions or expectations upon which these
forward-looking statements are based will occur. These forward-looking
statements are subject to risks, uncertainties and assumptions, including those
discussed elsewhere in this Information Circular. Although Assure believes that
the expectations represented in such forward-looking statements are reasonable,
there can be no assurance that these expectations will prove to be correct. Some
of the risks which could affect Assure's and GEOCAN's future results and could
cause the results to differ materially from those expressed in these
forward-looking statements include: the impact of general economic conditions in
Canada and the United States; industry conditions, including fluctuations in the
price of oil and natural gas and royalties payable in respect of oil and gas
production; the impact of governmental regulation of the oil and gas industry,
including environmental regulation; fluctuations in foreign exchange or interest
rates; stock market volatility; the need to obtain required approvals from
regulatory authorities; the uncertainty inherent in estimating oil and gas
reserves; the impact of competition; difficulties encountered during the
exploration for and production of oil and gas; variations in production and
problems inherent to the marketability of oil and gas, including the proximity
to and capacity of oil and gas pipelines and processing equipment; reservoir
characteristics; and the uncertainty inherent in attracting capital.

The information set forth under the heading "Part III - Information Relating to
GEOCAN, Post-Arrangement - Risk Factors" in this Information Circular and under
"Risk Factors" in Appendix D and Appendix E attached hereto, identifies
additional factors that could affect Assure's and GEOCAN's respective
operations, results and performance. Assure Securityholders should carefully
consider these factors.

The Assure Meeting

      The Meeting will be held on Wednesday, September 7, 2005 at 10:00 a.m.
(Calgary time), at the offices of Bennett Jones LLP, 4500, 855 - 2nd Street
S.W., Calgary, Alberta, for the purpose of considering and, if deemed advisable,
passing, with or without variation, the Arrangement Resolution approving the
Arrangement.

Description of the Arrangement

      On July 9, 2005, GEOCAN and Assure entered into the Arrangement Agreement,
as amended and restated on August 2, 2005, a copy of which is attached as
Appendix B to this Information Circular. The Arrangement Agreement provides for
the implementation of the Plan of Arrangement, a copy of which is attached as
Exhibit 1 to the Arrangement Agreement. The description in this Information
Circular of the Arrangement and the Arrangement Agreement is a summary only and
is qualified in its entirety by reference to the full text of the Arrangement
Agreement and the Plan of Arrangement.

      The following summarizes the events which will occur under the Plan of
Arrangement on the Effective Date if all conditions to the implementation of the
Arrangement (including obtaining the requisite Court and Assure Securityholder
approvals) have been satisfied or waived:

      (a)   all of the issued and outstanding Assure Shares, Assure Preferred
            Shares and Assure Warrants held by Dissenting Securityholders as of
            the Effective Time shall be deemed to have been transferred to
            Assure and cancelled and shall cease to be issued and outstanding
            and, as of the Effective Time, such Dissenting Securityholders shall
            cease to have any rights as Assure Securityholders, other than the
            right to be paid the fair value of their Assure Shares, Assure
            Preferred Shares or Assure Warrants, as the case may be, and the
            names of such Dissenting Securityholders shall be removed from the
            register of holders of Assure Shares, Assure Preferred Shares and
            Assure Warrants, as applicable; and

      (b)   all of the issued and outstanding Assure Shares beneficially owned
            by Assure Shareholders at the Effective Time shall be transferred to
            GEOCAN, solely in exchange for the issue by GEOCAN, to such Assure
            Shareholders in respect of such Assure Shares, of fully paid and
            non-assessable common shares of GEOCAN on the basis of 0.7 of a
            GEOCAN Share for each Assure Share.

                                     - 10 -

      No fractional GEOCAN Shares will be issued pursuant to the Arrangement. In
the event that the conversions contemplated by the Plan of Arrangement would
result in an Assure Shareholder being entitled to a fractional GEOCAN Share, the
number of GEOCAN Shares to be issued to each such former Assure Shareholder will
be rounded up to the next whole number of GEOCAN Shares. In calculating such
fractional interests, all Assure Shares held by an Assure Shareholder prior to
the Effective Time will be aggregated.

      The respective obligations of GEOCAN and Assure to complete the
transactions contemplated by the Plan of Arrangement are subject to a number of
conditions which must be satisfied or waived in order for the Arrangement to
become effective. If the Arrangement is approved by the Assure Securityholders,
the Final Order is obtained, and all of the conditions to completion of the
Arrangement are fulfilled or waived, Assure is required to file a copy of the
Final Order and the Articles of Arrangement with the Registrar under the ABCA in
order to give effect to the Arrangement.

Directors and Officers

      The GEOCAN Board, following the completion of the Arrangement, will be
composed of Messrs. Christopher J. Bloomer, Raymond P. Cej, Bradley J. Farris,
William C. Guinan, Garry W. Lohuis, Wayne S. Wadley and a nominee of Assure to
be named later. The senior officers of GEOCAN following the Arrangement will be
composed of the current senior officers of GEOCAN. See "Part III - Information
Relating to GEOCAN, Post Arrangement - Directors and Officers of GEOCAN" in this
Information Circular.

Benefits of the Arrangement

      The Assure Board and management believes that the Arrangement is in the
best interests of the Assure Securityholders and that the Arrangement provides a
number of benefits including:

      (a)   the combined company will have a larger production base and greater
            financial resources, enabling it to more effectively undertake and
            accelerate its oil and natural gas development and exploration
            opportunities;

      (b)   the combined company will have a focused and experienced management
            team with a strong record for creating shareholder value;

      (c)   the combined company will have increased operating efficiencies;

      (d)   the combined company will have increased market capitalization and a
            wider shareholder base allowing greater access to capital and
            improved liquidity;

      (e)   the combined company will have a stronger balance sheet providing
            for greater financial flexibility;

      (f)   the combined company will have a balanced inventory of exploration
            and development projects; and

      (g)   the transaction provides generally for the tax deferred rollover of
            Assure Shares into GEOCAN Shares under the Income Tax Act for Assure
            Shareholders resident in Canada and a tax free disposition of Assure
            Shares into GEOCAN Shares for Assure Shareholders not resident in
            Canada. See "Part II - The Arrangement - Certain Canadian Federal
            Income Tax Considerations" in this Information Circular.

                                     - 11 -


Effect of the Arrangement

      Each Assure Shareholder, other than Dissenting Securityholders, will be
deemed to transfer the Assure Shares held by them to GEOCAN in exchange for the
applicable number of GEOCAN Shares determined by the Exchange Ratio. Each Assure
Preferred Share, other than Assure Preferred Shares held by Dissenting
Securityholders, shall remain an Assure Preferred Share. Each Assure Warrant,
other than Assure Warrants held by Dissenting Securityholders, will become
warrants exercisable into GEOCAN Shares in accordance with the terms of the
Assure Warrants. Assure has agreed, in the Arrangement Agreement, to use
reasonable commercial efforts to cause the holders of Assure A Warrants and
Assure B Warrants to exercise such warrants. Assure and certain Assure
Warrantholders may enter into agreements to exercise such warrants whereby the
Assure Warrantholder, rather than paying the exercise price and receiving an
Assure Share, will receive the in-the-money amount of the Assure Warrant plus a
premium for the remaining time value of the Assure Warrant, payable in Assure
Shares.

      Assuming there are no Dissenting Securityholders and prior to the exercise
of any Assure Warrants, there will be approximately 41,063,171 GEOCAN Shares
outstanding after giving effect to the Arrangement, on a non-diluted basis.
Current GEOCAN Shareholders will hold approximately 23,961,973 GEOCAN Shares, on
a non-diluted basis, immediately following completion of the Arrangement,
representing approximately 58% of the issued and outstanding GEOCAN Shares
(non-diluted). Current Assure Securityholders will hold approximately 17,101,198
GEOCAN Shares (on a non-diluted basis) immediately following completion of the
Arrangement, representing approximately 42% of the issued and outstanding GEOCAN
Shares (non-diluted). The foregoing information is approximate due to the
rounding of fractional shares pursuant to the Arrangement and the exercise of
the Assure Warrants.

      The following graph illustrates the effect of the Arrangement on Assure
Securityholders.

                                     - 12 -

The Arrangement Agreement

      GEOCAN and Assure entered into the Arrangement Agreement, which provides
for implementation of the Arrangement pursuant to Section 193 of the ABCA. The
Arrangement Agreement contains representations and warranties of and from each
of GEOCAN and Assure, covenants (including restrictions on interim operations
and other matters), and various conditions precedent, with respect to each of
Assure and GEOCAN, to the implementation of the Arrangement. See "Part II - The
Arrangement - The Arrangement Agreement".

Procedure for the Arrangement to Become Effective

Procedural Steps

      The Arrangement is proposed to be carried out pursuant to Section 193 of
the ABCA. The following procedural steps must be taken in order for the
Arrangement to become effective:

      (a)   the Arrangement must be approved by the Assure Securityholders in
            the manner set forth in the Interim Order;

      (b)   the Court must grant the Final Order approving the Arrangement;

      (c)   all conditions precedent to the Arrangement, as set forth in the
            Arrangement Agreement, must be satisfied or waived by the
            appropriate party; and

      (d)   the Final Order and Articles of Arrangement in the form prescribed
            by the ABCA must be filed with the Registrar.

Securityholder Approvals

      The Interim Order provides that the Arrangement Resolution is required to
be approved by 66 2/3% of all of the votes cast on such resolutions by Assure
Securityholders, voting together as a class, present in person or by proxy at
the Meeting such that (a) each Assure Shareholder is entitled to one vote for
each Assure Share held, (b) each Assure Preferred Shareholder is entitled to one
vote for each Assure Preferred Share held, and (c) each Assure Warrantholder is
entitled to one vote for each Assure Share such holder would be entitled to
receive upon the exercise of the Assure Warrants.

      See "Part II - The Arrangement - Procedure for the Arrangement to Become
Effective" in this Information Circular. See also Appendix A to this Information
Circular for the full text of the Arrangement Resolution.


Court Approval
      The ABCA provides that the Arrangement requires Court approval. On August
5, 2005 Assure obtained the Interim Order providing for the calling and holding
of the Meeting and other procedural matters. The Interim Order is attached as
Appendix C to this Information Circular.

      Subject to the terms of the Arrangement Agreement and to the Arrangement
Resolution being approved at the Meeting in the manner required by the Interim
Order, Assure will make application to the Court for the Final Order at the
Court, 611 - 4th Street S.W., Calgary, Alberta on September 7, 2005 at 1:15 p.m.
(Calgary time) or as soon thereafter as counsel may be heard. Any Assure
Securityholder or other interested party who wishes to participate in or be
represented at the hearing may do so, subject to filing with the Court and
serving on Assure, a Notice of Intention to Appear on or before 4:00 p.m. on
Thursday, September 1, 2005, together with any evidence or materials which are
to be presented to the Court, setting out the Assure Securityholder's or other
interested party's address for service and indicating whether such Assure
Securityholder or other interested party intends to support or oppose the
petition or make submissions. See "Notice of Petition" in this Information
Circular. See "Part II - The Arrangement - Procedures for the Arrangement to
become Effective - Court Approval".

                                     - 13 -

Regulatory Approvals

      The Arrangement requires approval of certain regulatory authorities. The
Arrangement Agreement provides that these approvals are conditions precedent to
the Arrangement becoming effective. GEOCAN will make application to such
authorities prior to the Effective Date in order to obtain all approvals
required in respect of the Arrangement. There can be no assurance that the
requisite approvals will be granted on a timely basis or on conditions
satisfactory to Assure and GEOCAN. See "Part II - The Arrangement - Procedures
for the Arrangement to become Effective - Regulatory Approvals".

Timing

      If the Meeting is held as scheduled and is not adjourned and the other
necessary conditions of the Arrangement are satisfied or waived, Assure will
apply to the Court for the Final Order approving the Arrangement. If the Final
Order is obtained on September 7, 2005 in form and substance satisfactory to
GEOCAN and Assure, and all other conditions specified are satisfied or waived,
Assure expects the Effective Date of the Arrangement will be September 8, 2005.
See "Part II - The Arrangement - Timing".

Fairness Opinion

      The Assure Board retained Haywood Securities as its financial advisors
pursuant to an agreement effective April 21, 2005. Pursuant to this agreement,
Haywood Securities has considered the fairness, from a financial point of view,
of the Arrangement to the Assure Shareholders.

      The Assure Board has received the Fairness Opinion from Haywood
Securities, which states that, on the basis of the assumptions and
considerations summarized therein and based on the Exchange Ratio, Haywood
Securities views the Arrangement as fair, from a financial point of view to the
Assure Shareholders.

      See "Part II - The Arrangement - Fairness Opinion" and the Fairness
Opinion attached as Appendix H to this Information Circular. The Fairness
Opinion should be read carefully and in its entirety.

Recommendation of the Assure Board

      The Assure Board has determined that the Arrangement is in the best
interests of Assure and the Assure Securityholders and is fair to the Assure
Securityholders and, as such, has authorized the submission of the Arrangement
to the Assure Securityholders for approval and to the Court for the Final Order.

      The Assure Board unanimously recommends that Assure Securityholders vote
in favour of the Arrangement Resolution. See "Part II - The Arrangement -
Recommendation of the Assure Board".

Interests and Intentions of Directors, Officers, Insiders and Significant
Securityholders in Matters to be Acted Upon

      As of the date hereof, the directors and officers of Assure, as a group,
beneficially own or control, directly or indirectly, or exercise control or
direction over, 445,600 (?%) Assure Shares. The directors and officers of Assure
have indicated their intention to vote the Assure Shares and Assure Warrants
beneficially held or controlled by them in favour of the Arrangement. All of the
directors and officers of Assure have entered into the Lockup Agreements
requiring them to vote their Assure Securities in favour of the Arrangement. See
"Part II - The Arrangement - Interests and Intentions of Directors, Officers,
Insiders and Significant Securityholders in Matters to be Acted Upon".

                                     - 14 -


Expenses of The Arrangement

      If completed, all out-of-pocket expenses incurred in connection with the
Arrangement, the transactions contemplated thereby, the Meeting and the
preparation and mailing of the Information Circular, including legal and
accounting fees, printing costs, financial advisor fees and all disbursements by
advisors, shall be borne by the party incurring such expenses. See "Part II -
The Arrangement - Expenses of the Arrangement".

Stock Exchange Listings

      The Assure Shares are currently quoted on the OTCBB under the symbol
"ASURF" and on the Frankfurt Stock Exchange under the symbol "ASL" (WKN 357954).
On July 8, 2005, the last trading day prior to the initial date of the
announcement of the proposed Arrangement, the closing price of the Assure Shares
on the OTCBB was US$0.71 per share. On August 4, 2005, the closing price of the
Assure Shares on the OTCBB was $1.07.

      The GEOCAN Shares are listed and posted for trading on the TSX under the
symbol "GCA". On July 8, 2005, the last trading day prior to the initial date of
the announcement of the proposed Arrangement, the closing price of the GEOCAN
Shares on the TSX was $1.52 per share. On August 4, 2005, the closing price of
the GEOCAN Shares on the TSX was $1.97.

      It is a condition to the completion of the Arrangement that the TSX shall
have approved the listing of the GEOCAN Shares. Application has been made to
list the GEOCAN Shares issued to Assure Shareholders and Assure Warrantholders
on the TSX. See "Part II - The Arrangement - Stock Exchange Listings".

Certain Canadian Federal Income Tax Consequences

      Generally, unless an Assure Shareholder chooses to recognize a gain or
loss on the exchange of Assure Shares for GEOCAN Shares under the Arrangement,
no capital gain or capital loss will result. See "Part II - The Arrangement -
Certain Canadian Federal Income Tax Consequences".

Right of Dissent

      Pursuant to the Interim Order, registered Assure Securityholders have been
granted the right to dissent in respect of the Arrangement Resolution, and, if
the Arrangement becomes effective, to be paid the fair value of their securities
in accordance with the provisions of Section 191 of the ABCA, as modified by the
Interim Order. To exercise such right, Assure must receive from the Dissenting
Securityholder a written objection to the Arrangement Resolution, delivered to
Assure, c/o Bennett Jones LLP, 4500 Bankers Hall East, 855 - 2nd Street S.W.,
Calgary, Alberta, T2P 4K7, Attention: Mr. Ken Lenz, by 5:00 p.m. (Calgary time)
two Business Days before the Meeting, and the Dissenting Securityholder must
otherwise comply with Section 191 of the ABCA, as modified by the Interim Order.
See Appendices C and G to this Information Circular for a copy of the Interim
Order and the provisions of Section 191 of the ABCA, respectively.


      The statutory provisions covering the Dissent Rights are technical and
complex. Failure to strictly comply with any of the requirements set forth in
Section 191 of the ABCA, as modified by the Interim Order, may result in the
loss of the Dissent Rights. Beneficial Holders whose Assure Securities are
registered in the name of a broker, custodian, nominee or other intermediary who
wish to dissent should be aware that only the registered holders of such
securities are entitled to dissent. Accordingly, a Beneficial Holder desiring to
exercise dissent rights must make arrangements for the Assure Securities
beneficially owned by such Beneficial Holder to be registered in his or her name
prior to the time the written objection to the Arrangement Resolution is
required to be received by Assure, or alternatively, make arrangements for the
registered holder of his or her Assure Securities to dissent on his or her
behalf. Pursuant to the Interim Order, an Assure Securityholder that exercises
the Dissent Rights may not exercise the Dissent Rights in respect of only a
portion of such holder's securities. See "Part II - The Arrangement - Right of
Dissent" in this Information Circular.

                                     - 15 -

         It is a condition to the Arrangement that Assure Securityholders of not
more than 10% of the aggregate of the outstanding Assure Shares, Assure
Preferred Shares and Assure Warrants shall have exercised rights of dissent in
respect to the Arrangement.

     Selected Reserves and Operational Information

      It should not be assumed that the estimates of future net revenues
presented in the tables below represent the fair market value of the reserves.
There is no assurance that the constant prices and costs assumptions and
forecast prices and costs assumptions will be attained and variances could be
material. The recovery and reserve estimates of the Corporation's crude oil,
natural gas liquids and natural gas reserves provided herein are estimates only
and there is no guarantee that the estimated reserves will be recovered. Actual
crude oil, natural gas and natural gas liquid reserves may be greater than or
less than the estimates provided herein.

      The following table sets forth certain reserves information for GEOCAN and
Assure and pro-forma combined reserves information for GEOCAN and Assure, for
the year ended December 31, 2004 after giving effect to the Arrangement from

Notes:
(1)  All pricing information for constant and forecast prices and costs and
     other pricing assumptions relating to GEOCAN and Assure are included in
     Appendices D and E to this Information Circular, respectively.

(2)  Pro-Forma combined reserves information is calculated solely by combining
     the reserves of Assure and GEOCAN. No adjustments have been made to reflect
     synergies or efficiencies resulting from the Arrangement or for
     Saskatchewan capital tax or abandonment costs, neither of which have been
     applied in the case of GEOCAN. Actual reserves information of GEOCAN
     subsequent to the Arrangement may be materially different from these
     figures and readers are cautioned not to place undue reliance on such
     information.

(3)  Assure disposed of producing properties in the Chestermere area of Alberta
     in early January 2005. Assure's working interest proved and proved plus
     probable reserves as estimated by Sproule for this property as of December
     31, 2004 was 417 Mboe and 659 Mboe, respectively.

(4)  Pro-Forma combined average prices information reflects a weighted average
     percentage of approximately one third Assure and two-thirds GEOCAN. Actual
     prices of GEOCAN subsequent to the Arrangement may be materially different
     from these figures. The Assure Securityholders are advised to avoid placing
     undue reliance on these figures.

      GEOCAN has provided the information contained in this Information Circular
concerning GEOCAN and its businesses, including its financial information and
financial statements. Assure assumes no responsibility for the accuracy or
completeness of such information, nor for any omission on the part of GEOCAN of
facts or events which may affect the accuracy of such information.

      GEOCAN and Assure are, and GEOCAN will be, subject to certain risks that
should be carefully considered. These risks include volatility of commodity
prices, operational risks, and an inability to replace reserves. See "Part III -
Information Relating to GEOCAN, Post-Arrangement - Risk Factors" in the
Information Circular and "Risk Factors" in Appendices D & E attached hereto.

                         PART I - GENERAL PROXY MATTERS
Purpose of Solicitation


      This Information Circular is provided in connection with the solicitation
of proxies by the management of Assure for use at the Meeting to be held at the
offices of Bennett Jones LLP, 4500, 855 - 2nd Street S.W., Calgary, Alberta, on
Wednesday, September 7, 2005 at 10:00 a.m. (Calgary time) and at any
adjournments thereof, for the purposes set forth in the Notice of Meeting
accompanying this Information Circular.

      Information contained herein is given as of August 5, 2005 unless
otherwise specifically stated. All sums are expressed in Canadian dollars unless
otherwise indicated.

Solicitation and Revocation of Proxies


      It is expected that the solicitation will be primarily by mail, but some
proxies may be solicited personally or by telephone, facsimile transmission or
other electronic means by the directors, officers or employees of Assure. No
remuneration will be paid to any person for soliciting proxies, but Assure may,
upon request, pay to brokerage firms, fiduciaries or other persons holding
Assure Securities in their name for others, the charges incurred for
distributing the form of proxy ("Form of Proxy") to those persons for whom they
hold Assure Securities. The cost of any such solicitation will be borne by
Assure.

      The Form of Proxy is solicited by and on behalf of the management of
Assure. Harvey Lalach, President and Chief Executive Officer of Assure and,
alternatively, Colin McNeil, Director of Assure, are named as proxies in the
enclosed Form of Proxy for Assure Securityholders at the Meeting.

      An Assure Securityholder submitting a proxy has the right to appoint a
nominee (who need not be an Assure Securityholder) to represent him or her at
the Meeting other than the persons designated by management in the enclosed Form
of Proxy, by inserting the name of the Assure Securityholder's chosen nominee in
the space provided for that purpose on the applicable enclosed Form of Proxy,
and by striking out the names of the management designees printed thereon or by
completing another proper instrument of proxy. Such Assure Securityholder should
notify the nominee of the appointment, obtain the nominee's consent to act as
proxy and instruct the nominee as to how the Assure Securityholder's Assure
Shares, Assure Preferred Shares or Assure Warrants are to be voted.

      A Form of Proxy will not be valid for the Meeting or any adjournments
thereof unless it is in writing and signed by the Assure Securityholder or by
his or her attorney authorized in writing or, if the Assure Securityholder is a
corporation, by a duly authorized officer or attorney of such corporation, and
forwarded so it reaches or is deposited with Continental, 17 Battery Place, New
York, NY 10004, not later than twenty-four hours (excluding Saturdays, Sundays
and statutory holidays) prior to the time fixed for the Meeting, or any
adjournments thereof.

      An Assure Securityholder who has submitted a proxy may revoke it at any
time prior to the exercise of that proxy. If a person who has given a proxy
attends personally at the Meeting such person may revoke the proxy and vote in
person. In addition to revocation in any other manner permitted by law, a proxy
may be revoked by instrument in writing executed by the Assure Securityholder or
his or her attorney authorized in writing or, if the Assure Securityholder is a
corporation, by a duly authorized officer or attorney of such corporation, and
deposited either at the head office of Assure at any time up to 4:30 p.m.
(Calgary time) on the last Business Day before the day of the Meeting, or with
the Chairman of the Meeting on the day of the Meeting, and upon either of such
deposits, the proxy is revoked. An Assure Securityholder who revokes his or her
proxy and does not replace it with another that is deposited with Continental at
least twenty-four hours (excluding Saturdays, Sundays and holidays) before the
time of the Meeting may not vote his or her Assure Securities in any manner at
the Meeting.

                                      19


Voting Shares and Principal Holders Thereof

      The Assure Board has fixed August 2, 2005 as the record date for the
determination of Assure Securityholders entitled to receive notice of the
Meeting. Assure Shareholders and Assure Preferred Shareholders of record on that
date are entitled to receive notice of and attend the Meeting and to vote
thereat on the basis of one vote for each Assure Share and Assure Preferred
Shares held, except to the extent that: (i) a registered Assure Shareholder or
Assure Preferred Shareholder has transferred the ownership of any Assure Shares
or Assure Preferred Shares subsequent to such date; and (ii) the transferee of
those Assure Shares or Assure Preferred Shares produces properly endorsed share
certificates, or otherwise establishes that he or she owns such shares and
demands, not later than ten days before the Meeting, that his or her name be
included on the list of the Assure Securityholders entitled to vote at the
Meeting, in which case the transferee shall be entitled to vote such Assure
Shares or Assure Preferred Shares at the Meeting. Assure Warrantholders of
record on the record date are entitled to receive notice of and attend the
Meeting and to vote thereat, together with the Assure Shareholders, on the basis
of one vote for each Assure Share such holder would be entitled to receive upon
the valid exercise of the Assure Warrants. As at the date hereof, there were
issued and outstanding 24,430,284 Assure Shares, 22,750 Assure Preferred Shares
(consisting of 17,500 Series A Shares and 5,250 Series B Shares) and 8,906,700
Assure Warrants. For the principal holders of Assure Securities, see "Principal
Shareholders" in Appendix E to this Information Circular.

      Pursuant to the by-laws of Assure, as modified by the Interim Order,
business may be transacted at the Meeting if there are not less than two persons
present at the Meeting, holding or representing not less than 10% of the Assure
Securities entitled to be voted at the Meeting. The Interim Order provides that
if no quorum is present within thirty minutes of the appointed time for the
Meeting, the Meeting shall stand adjourned to a date, as determined by the
Chairman of the Meeting, which is not less than seven days and not more than
thirty days after the Meeting. The Interim Order also provides that at such
adjourned Meeting, those persons present in person or by proxy and entitled to
vote at such Meeting will constitute a quorum at such adjourned Meeting.

Advice to Beneficial Holders of Assure Shares


      The information set forth in this section is of significant importance to
a substantial number of Assure Shareholders who do not hold their Assure Shares
in their own name. Assure Shareholders who do not hold their Assure Shares in
their own name should note that only proxies deposited by Assure Shareholders
whose names appear on the records of Assure as the registered holders of Assure
Shares can be recognized and acted upon at the Meeting. If Assure Shares are
listed in an account statement provided to an Assure Shareholder by a broker,
then in almost all cases those Assure Shares will not be registered in such
Assure Shareholder's name on the records of Assure. Such Assure Shares will more
likely be registered under the name of the Assure Shareholder's broker or an
agent of that broker. In Canada, the vast majority of such Assure Shares are
registered in the name of CDS & Co., the registration name for The Canadian
Depository for Securities Limited, which company acts as a nominee for many
Canadian brokerage firms. Assure Shares held by brokers or their nominees can
only be voted for or against resolutions upon the instructions of the Beneficial
Holder. Without specific instructions, brokers/nominees are prohibited from
voting Assure Shares for their clients. Assure does not know for whose benefit
the Assure Shares registered in the name of CDS & Co. are held.

                                      20

      Applicable regulatory policy requires intermediaries/brokers to seek
voting instructions from Beneficial Holders in advance of securityholders'
meetings. Every intermediary/broker has its own mailing procedures and provides
its own return instructions, which should be carefully followed by Beneficial
Holders in order to ensure that their Assure Shares are voted at the Meeting.
The purpose of a form of proxy supplied to a Beneficial Holder by its broker is
limited to instructing the broker how to vote on behalf of the Beneficial
Holder. The majority of brokers now delegate responsibility for obtaining
instructions from clients to ADP. ADP typically mails a scannable Voting
Instruction Form in lieu of the Form of Proxy issued by Assure. Beneficial
Holders are requested to complete and return the Voting Instruction Form to ADP
by mail or facsimile. Alternatively, Beneficial Holders can call a toll-free
telephone number or access ADP's dedicated voting website at
www.proxyvotecanada.com to deliver their voting instructions and vote the Assure
Shares held by them. ADP then tabulates the results of all instructions received
and provides appropriate instructions respecting the voting of Assure Shares to
be represented at the Meeting. A Beneficial Holder receiving a Voting
Instruction Form cannot use that Voting Instruction Form to vote Assure Shares
directly at the Meeting as the Voting Instruction Form must be returned as
directed by ADP well in advance of the Meeting in order to have the Assure
Shares voted. Beneficial Holders who receive forms of proxies or voting
materials from organizations other than ADP should complete and return such
forms of proxies or voting materials in accordance with the instructions on such
materials in order to properly vote their Assure Shares at the Meeting.

Voting of Proxies


      The persons named in the enclosed Form of Proxy will, if the instructions
are clear, vote the Assure Shares, Assure Preferred Shares or Assure Warrants
represented by that Form of Proxy and, where the Assure Securityholders specify
a choice with respect to any matter to be acted upon, the Assure Shares, Assure
Preferred Shares or Assure Warrants will be voted on in accordance with the
specification so made.

      In the absence of such specification, the Assure Shares, Assure Preferred
Shares or Assure Warrants represented by this Form of Proxy will be voted in
favour of the matters to be acted upon as set out herein. The persons appointed
under the Form of Proxy furnished by Assure are conferred with discretionary
authority with respect to amendments or variations of those matters specified in
the Form of Proxy and Notice of Meeting and with respect to any other matters
which may properly be brought before the Meeting. In the event that amendments
or variations to matters identified in the Notice of Meeting are properly
brought before the Meeting, it is the intention of the persons designated in the
enclosed Form of Proxy to vote in accordance with their best judgement on such
matter or business. At the time of printing this Information Circular, Assure
knows of no such amendment, variation or other matter.


                            PART II - THE ARRANGEMENT

Background to the Arrangement

      On June 17, 2005, Assure and GEOCAN signed a letter of intent, which was
amended by a letter agreement dated June 29, 2005, to negotiate a formal
agreement to effect the business combination of Assure and GEOCAN by means of a
share exchange on the basis of the Exchange Ratio. Pursuant to the letter of
intent it was agreed that the acquisition would be structured in the most
advantageous manner for both parties, giving consideration to tax and regulatory
implications. The letter of intent provided that the formal agreement was
subject to the completion of due diligence, the good faith negotiation of a
definitive arrangement and certain exclusivity and confidentiality arrangements.
The parties announced the Arrangement Agreement on July 11, 2005.

      The Assure Board retained Haywood Securities as its financial advisor
pursuant to an agreement effective April 21, 2005. Pursuant to this agreement,
Haywood Securities agreed to consider the fairness, from a financial point of
view, of the Arrangement to the Assure Shareholders. GEOCAN and Assure, with the
assistance of their respective legal and financial advisors, proceeded to
negotiate the terms of the Arrangement Agreement.

      Haywood Securities has advised the Assure Board that it would be in a
position to provide the Fairness Opinion. The Assure Board has determined that
the proposed Arrangement is in the best interests of Assure and the Assure
Securityholders, has resolved to recommend that Assure Securityholders vote in
favour of the Arrangement Resolution and has authorized the negotiation,
entering into and execution of the Arrangement Agreement.

      On July 9, 2005, the parties executed the Arrangement Agreement and
announced the definitive terms of the proposed transaction. On August 2, 2005,
the parties executed the amended and restated Arrangement Agreement. On August
5, 2005, the Assure Board approved the Information Circular and the application
to the Court for the Interim Order.

                                      21

Description of the Arrangement


      On July 9, 2005, GEOCAN and Assure entered into the Arrangement Agreement,
a copy of which is attached as Appendix B to this Information Circular. GEOCAN
and Assure entered into an amended and restated Arrangement Agreement on August
2, 2005, which agreement is effective as of July 8, 2005. The Arrangement
Agreement provides for the implementation of the Plan of Arrangement, a copy of
which is attached as Exhibit 1 to the Arrangement Agreement. The description in
this Information Circular of the Arrangement and the Arrangement Agreement is a
summary only and is qualified in its entirety by reference to the full text of
the Arrangement Agreement and the Plan of Arrangement.

      The following summarizes the events which will occur under the Plan of
Arrangement on the Effective Date if all conditions to the implementation of the
Arrangement (including obtaining the requisite Court and Assure Securityholder
approvals) have been satisfied or waived:

      (a)   all of the issued and outstanding Assure Shares, Assure Preferred
            Shares and Assure Warrants held by Dissenting Securityholders as of
            the Effective Time shall be deemed to have been transferred to
            Assure and cancelled and shall cease to be issued and outstanding
            and, as of the Effective Time, such Dissenting Securityholders shall
            cease to have any rights as Assure Securityholders, other than the
            right to be paid the fair value of their Assure Shares, Assure
            Preferred Shares or Assure Warrants, as the case may be, and the
            names of such Dissenting Securityholders shall be removed from the
            register of holders of Assure Shares, Assure Preferred Shares and
            Assure Warrants, as applicable; and

      (b)   all of the issued and outstanding Assure Shares beneficially owned
            by Assure Shareholders at the Effective Time shall be transferred to
            GEOCAN, solely in exchange for the issue by GEOCAN, to such Assure
            Shareholders in respect of such Assure Shares, of GEOCAN on the
            basis of 0.7 of a GEOCAN Share for each Assure Share.

      No fractional GEOCAN Shares will be issued pursuant to the Arrangement. In
the event that the conversions contemplated by the Plan of Arrangement would
result in an Assure Shareholder being entitled to a fractional GEOCAN Share, the
number of GEOCAN Shares to be issued to each such former Assure Shareholder will
be rounded up to the next whole number of GEOCAN Shares. In calculating such
fractional interests, all Assure Shares held by Assure Shareholders prior to the
Effective Time will be aggregated.

      The respective obligations of GEOCAN and Assure to complete the
transactions contemplated by the Plan of Arrangement are subject to a number of
conditions which must be satisfied or waived in order for the Arrangement to
become effective. If the Arrangement is approved by the Assure Securityholders,
the Final Order is obtained, and all of the conditions to completion of the
Arrangement are fulfilled or waived, Assure is required to file a copy of the
Final Order and the Articles of Arrangement with the Registrar under the ABCA in
order to give effect to the Arrangement.

Directors and Officers

      The GEOCAN Board, following the completion of the Arrangement, will be
composed of Christopher J. Bloomer, Raymond P. Cej, Bradley J. Farris, William
C. Guinan, Garry W. Lohuis, Wayne S. Wadley and a nominee of Assure to be named
later. The senior officers of GEOCAN, following the Arrangement, will be
composed of the current senior officers of GEOCAN. See "Part III - Information
Relating to GEOCAN, Post Arrangement - Directors and Officers of GEOCAN" in this
Information Circular.

Benefits of the Arrangement


         The Assure Board believes that the Arrangement is in the best interests
of the Assure Securityholders and that the Arrangement provides a number of
benefits including:

                                      22

      (a)   the combined company will have a larger production base and greater
            financial resources, enabling it to more effectively undertake and
            accelerate its oil and natural gas development and exploration
            opportunities;

      (b)   the combined company will have a focused and experienced management
            team with a strong record for creating shareholder value;

      (c)   the combined company will have increased operating efficiencies;

      (d)   the combined company will have increased market capitalization and a
            wider shareholder base allowing greater access to capital and
            improved liquidity;

      (e)   the combined company will have a stronger balance sheet providing
            for greater financial flexibility;

      (f)   the combined company will have a well balanced inventory of
            exploration and development projects; and

      (g)   the transaction provides generally for the tax deferred rollover of
            Assure Shares into GEOCAN Shares under the Income Tax Act for Assure
            Shareholders resident in Canada and a tax free disposition of Assure
            Shares into GEOCAN Shares for Assure Shareholders not resident in
            Canada. See "Part II - The Arrangement - Certain Canadian Federal
            Income Tax Considerations" in this Information Circular.

Effect of the Arrangement


      Each Assure Shareholder, other than Dissenting Securityholders, will be
deemed to transfer the Assure Shares held by them to GEOCAN in exchange for the
applicable number of GEOCAN Shares determined by the Exchange Ratio. Each Assure
Preferred Share, other than Assure Preferred Shares held by Dissenting
Securityholders, shall remain an Assure Preferred Share. Each Assure Warrant,
other than Assure Warrants held by Dissenting Securityholders, will become
warrants exercisable into GEOCAN Shares in accordance with the terms of the
Assure Warrants. Assure has agreed, in the Arrangement Agreement, to use
reasonable commercial efforts to cause the holders of Assure A Warrants and
Assure B Warrants to exercise such warrants. Assure and certain Assure
Warrantholders may enter into agreements to exercise such warrants whereby the
Assure Warrantholder, rather than paying the exercise price and receiving an
Assure Share, will receive the in-the-money amount of the Assure Warrant plus a
premium for the remaining time value of the Assure Warrant, payable in Assure
Shares.

      Assuming there are no Dissenting Securityholders and prior to the exercise
of any Assure Warrants, there will be approximately 41,063,171 GEOCAN Shares
outstanding after giving effect to the Arrangement, on a non-diluted basis.
Current GEOCAN Shareholders will hold approximately 23,961,973 GEOCAN Shares, on
a non-diluted basis, immediately following completion of the Arrangement,
representing approximately 58% of the issued and outstanding GEOCAN Shares
(non-diluted). Current Assure Securityholders will hold approximately 17,101,198
GEOCAN Shares (on a non-diluted basis) immediately following completion of the
Arrangement, representing approximately 42% of the issued and outstanding GEOCAN
Shares (non-diluted). The foregoing information is approximate due to the
rounding of fractional shares pursuant to the Arrangement and the exercise of
the Assure Warrants.

                                      23

                  consent of lenders to GEOCAN or Assure, required in connection
                  with the matters contemplated by the Arrangement Agreement and
                  the Arrangement shall have been obtained; and

            (xi)  if applicable, the relevant waiting period in section 123 of
                  the Competition Act (Canada) shall have expired and: (i) an
                  advance ruling certificate ("ARC") pursuant to section 102 of
                  the Competition Act shall have been issued by the Commissioner
                  of the Competition Bureau ("Commissioner") appointed under the
                  Competition Act (Canada); or (ii) a "no action letter"
                  satisfactory to each of GEOCAN and Assure, acting reasonably,
                  indicating that the Commissioner has determined not to make an
                  application for an order under section 92 of the Competition
                  Act (Canada) shall have been received from the Commissioner,
                  and any terms and conditions attached to any such letter shall
                  be acceptable to each of GEOCAN and Assure, acting reasonably;
                  and in addition, in the event that the ARC or "no action"
                  letter described in (i) or (ii) in the foregoing is issued,
                  there shall be no threatened or actual application by the
                  Commissioner for an order under section 92 or 100 of the
                  Competition Act (Canada).

The foregoing conditions are for the mutual benefit of GEOCAN and Assure and may
be waived, in whole or in part, by GEOCAN and Assure together, at any time.
Subject to Section 10.4 of the Arrangement Agreement, if any of the conditions
precedent set forth in this Article shall not be complied with or waived as
aforesaid on or before the date required for the performance thereof, GEOCAN or
Assure may, in addition to the other remedies they may have at law or in equity,
rescind and terminate the Arrangement Agreement by written notice to the other
party.

      (b) GEOCAN Conditions

The obligations of GEOCAN to complete the Arrangement are subject to fulfillment
of the following conditions precedent on or before the Effective Date:

            (i)   the representations and warranties made by Assure in Section
                  6.1 of the Arrangement Agreement shall be true as of the
                  Effective Date as if made on and as of such date (except to
                  the extent such representations and warranties speak to a
                  particular date and except, in the case of Section 6.1(e) of

                  have provided to GEOCAN a certificate of an officer of Assure

      (c) Assure Conditions

                  The obligation of Assure to complete the Arrangement is

                  precedent on or before the Effective Date:

            (i)   the representations and warranties made by GEOCAN in Section
                  7.1 of the Arrangement Agreement shall be true as of the
                  Effective Date as if made on and as of such date (except to
                  the extent such representation and warranty speaks as of a
                  particular date) except where the failure of such
                  representations and warranties to be true and correct would
                  not have a Material Adverse Effect on GEOCAN and GEOCAN shall
                  have provided to Assure a certificate of an officer of GEOCAN
                  certifying (to the best of his knowledge and not in his
                  personal capacity) as to such matters on the Effective Date;

            (ii)  GEOCAN shall have furnished Assure (all in form acceptable to
                  Assure, acting reasonably) with certified copies of the
                  resolutions duly passed by the board of directors of GEOCAN
                  approving the Arrangement Agreement and the consummation of
                  the transactions contemplated hereby;

            (iii) GEOCAN shall have complied in all material respects with its
                  covenants in the Arrangement Agreement and GEOCAN shall have
                  provided to Assure a certificate of an officer of GEOCAN
                  certifying (to the best of his knowledge and not in his
                  personal capacity) as to such compliance;

            (iv)  releases by GEOCAN and Assure of Assure's directors and
                  officers, and any employees who have provided releases
                  pursuant to Section 9.1(u) of the Arrangement Agreement, which
                  shall include normal course exceptions respecting
                  confidentiality, fraud, negligence, criminal behaviour,
                  willful misconduct or failure to act honestly, in good faith
                  and in the best interests of Assure, shall have been
                  delivered;

            (v)   GEOCAN shall have entered into written agreement effective as
                  of the Effective Date satisfactory to Assure, acting
                  reasonably, pursuant to which GEOCAN shall agree that, for a
                  period of three years after the Effective Date, GEOCAN shall
                  cause to be maintained directors' and officers' liability
                  insurance providing coverage on a "trailing" or "run-off"
                  basis for all present (to the Effective Date) and former
                  directors and officers of Assure with respect to claims
                  arising from facts or events which occurred before the
                  Effective Date, such insurance to have substantially the same
                  coverage limits and terms from time to time as GEOCAN provides
                  for its own directors and officers;

            (vi)  there shall not have occurred any Material Adverse Change in
                  respect of GEOCAN;

                                      28

            (vii) the Assure Shareholder Loan Mandatory Repayment shall have
                  occurred;

            (viii) the GEOCAN Shares issueable pursuant to the Arrangement shall
                  be freely tradable by the holders of such GEOCAN Shares
                  subject to requirements of general application, the TSX and in
                  respect of trades by control persons; and

            (ix)  Assure shall have received an opinion of legal counsel dated
                  as of the Effective Date, in respect of such matters related
                  to the transactions contemplated by the Arrangement Agreement
                  and the Arrangement as may reasonably be requested by Assure.

      The foregoing conditions precedent are for the benefit of Assure and may
be waived, in whole or in part, by Assure in writing at any time. Subject to
Section 10.4, if any of the conditions precedent set forth above shall not be
complied with or waived by Assure on or before the date required for the
performance thereof, Assure may, in addition to the other remedies they may have
at law or equity, rescind and terminate the Arrangement Agreement by written
notice from Assure to GEOCAN.


Non-Solicitation and Superior Proposals

      The Arrangement Agreement provides that:

      (a)   Assure shall immediately cease and cause to be terminated all
            solicitations, initiations, encouragements, discussions or
            negotiations, if any, with any persons conducted before the date of
            the Arrangement Agreement with respect to any Assure Acquisition
            Proposal and shall immediately request the return or destruction of
            all information provided to third parties, if any, who have entered
            into a confidentiality agreement with Assure relating to an Assure
            Acquisition Proposal and shall use all reasonable commercial efforts
            to ensure that such requests are honoured.

      (b)   Assure shall not, directly or indirectly, authorize or permit any of
            the officers, directors or employees of Assure or of any financial
            advisor, expert or other person acting on its behalf to:

            (i)   solicit, initiate or encourage (including, without limitation,
                  by way of furnishing information or entering into any form of
                  agreement, arrangement or understanding) an Assure Acquisition
                  Proposal;

            (ii)  enter into or participate in any discussions on negotiations
                  regarding an Assure Acquisition Proposal, or, except in the
                  ordinary course of business, furnish to any other person any
                  information with respect to the business, properties,
                  operations, prospects or conditions (financial or otherwise)
                  of Assure or an Assure Acquisition Proposal or otherwise
                  cooperate in any way with, or assist or participate in,
                  facilitate or encourage, any effort or attempt of any other
                  person to do or seek to do any of the foregoing; or

            (iii) waive, or otherwise forbear (except in respect of non material
                  matters) in the enforcement of, or enter into or participate
                  in any discussions, negotiations or agreements to waive or
                  otherwise forbear in respect of, any rights or other benefits
                  of Assure under confidential information agreements,
                  including, without limitation, any "standstill provisions"
                  thereunder;

            provided, however, that notwithstanding any other provisions hereof,
            Assure (and its directors, officers, employees and advisors) may:

            (iv)  engage in discussions or negotiations with a third party who
                  (without any solicitation, initiation or encouragement,
                  directly or indirectly, by Assure or any of the officers,
                  directors or employees of Assure or any financial advisor,
                  expert or other representative or agent acting on its behalf)
                  seeks to initiate such discussions or negotiations and,
                  subject to execution of a confidentiality agreement
                  substantially similar to the Confidentiality Agreement, may
                  furnish such third party information concerning Assure and its
                  business, properties and assets, in each case if, and only to
                  the extent that:

                                      29


                  (A)   the third party has first made a written bona fide
                        Assure Acquisition Proposal that is a Superior Proposal;
                        and

                  (B)   prior to furnishing such information to or entering into
                        discussions or negotiations with such third party,
                        Assure provides prompt notice to GEOCAN to the effect
                        that it is furnishing information to or entering into
                        discussions or negotiations with such third party
                        together with a copy of the confidentiality agreement
                        referenced above and if not previously provided to
                        GEOCAN, copies of all information provided to such third
                        party are provided to GEOCAN concurrently with the
                        provision of such information to such third party.
                        Assure shall immediately notify GEOCAN orally and in
                        writing of any inquiries, offers or proposals with
                        respect to any Assure Acquisition Proposal (including
                        without limitation, the terms and conditions of any such
                        proposal (and any amendments or changes thereto), the
                        identity of the person making it, and if not previously
                        provided to GEOCAN, copies of all information provided
                        to such person and all other information reasonably
                        requested by GEOCAN), shall keep GEOCAN informed of the
                        status and details of any such inquiry, offer or
                        proposal and answer GEOCAN's questions with respect
                        thereto.

(c)   Assure shall give GEOCAN 48 hours advance notice of any agreement (and the
      terms of such agreement) to be entered into with, or any information to be
      supplied to, any person making an inquiry, offer or proposal with respect
      to a Superior Proposal and shall confirm the determination of the Assure
      Board that the Assure Acquisition Proposal is a Superior Proposal. For a
      period of 48 hours from the time that Assure provides notice of such
      Superior Proposal to GEOCAN and any amendment thereto, together with the
      foregoing confirmation in respect of the determination of the Assure
      Board, the Assure Board and Assure agree not to accept, recommend or
      approve or enter into any agreement (an "Assure Proposed Agreement") to
      implement such a Superior Proposal or release the party from making the
      Superior Proposal from any standstill provisions. In addition, in respect
      of any Superior Proposal, Assure shall, and shall cause its financial and
      legal advisors to, negotiate in good faith with GEOCAN to make such
      adjustments in the terms and conditions of the Arrangement Agreement and
      the terms of the Arrangement as would enable Assure to proceed with the
      transaction contemplated herein, as amended, rather than the Superior
      Proposal. In the event that GEOCAN proposes to and does amend the
      Arrangement Agreement and the terms of the Arrangement to provide equal or
      superior value to that provided under the Superior Proposal within a
      period of 48 hours from the time that GEOCAN receives notice of the
      Superior Proposal and a copy of the Assure Proposed Agreement (and any
      amendments thereto), Assure shall not enter into any Assure Proposed
      Agreement regarding the Superior Proposal or any amendment thereof.

(d)   Notwithstanding Section 6.1(u) of the Arrangement Agreement in the event
      that, prior to the completion of the Arrangement, a Superior Proposal is
      offered or made to the Assure Securityholders or Assure, the Assure Board
      may fail to make, withdraw, modify or change any recommendation regarding
      the Arrangement if, in the opinion of the board of directors acting in
      good faith after written advice from outside counsel to such effect, which
      is reflected in the minutes of a meeting of the Assure Board (a copy of
      the relevant extract of which minutes shall be provided to GEOCAN), the
      making or failure to so withdraw, modify or change any recommendation
      regarding the Arrangement would be inconsistent with the performance by
      the directors of Assure of their fiduciary duties under applicable law,
      and provided Assure shall have complied with the provisions of Section 9.3
      of the Arrangement Agreement and paid the GEOCAN Break Fee to GEOCAN in
      the circumstances where such fee is payable.

                                      30

Payment of Break Fees

      Subject to Section 10.4 of the Arrangement Agreement, if at any time after
the date of this Agreement:

      (a)   the Assure Board fails to recommend that the Assure Securityholders
            approve the Arrangement or withdraws or, in any manner adverse to
            GEOCAN redefines, modifies or changes any of its recommendations
            referred to in Section 6(u) of the Arrangement Agreement, unless it
            has the right to do so under Section 9.4 of the Arrangement
            Agreement; or

      (b)   prior to the date of the Meeting:

            (i)   an Assure Acquisition Proposal that is a Superior Proposal is
                  publicly announced or made to Assure or the Assure
                  Securityholders;

            (ii)  the Superior Proposal has not been withdrawn or expired; and

                  (A)   the Assure Board fails to confirm to the Assure
                        Securityholders, within five business days after the
                        making of the Assure Acquisition Proposal its
                        recommendation that the Assure Securityholders reject
                        the Superior Proposal; or

                  (B)   Assure enters into an agreement (other than a
                        confidentiality agreement) with respect to the Superior
                        Proposal;

                          and the Arrangement is not approved at the Meeting; or

      (c)   Assure shall have breached, or failed to comply with, in any
            material respect, any of its covenants or other obligations under
            the Arrangement Agreement or any of the representations and
            warranties of Assure contained in the Arrangement Agreement shall
            not be true and correct in all material respects as of the date of
            the Arrangement Agreement, except where the failure of such
            representations and warranties to be true and correct would not have
            a Material Adverse Effect on Assure, or shall have ceased to be true
            and correct in any material respect thereafter, except where the
            failure of such representations and warranties to be true and
            correct would not have a Material Adverse Effect on Assure, (other
            than, in either case, as a direct result of and in direct response
            to a breach by GEOCAN of its obligations under the Arrangement
            Agreement);

      then Assure shall, within two business days after the first to occur of
      the events described above, pay to GEOCAN the GEOCAN Break Fee. Such
      payment shall be made in immediately available funds to an account
      designated by GEOCAN. The payment of the GEOCAN Break Fee to GEOCAN shall
      represent full and final settlement of all claims of GEOCAN arising in
      respect of the matter giving rise to such payment and GEOCAN shall have no
      further remedy or recourse in respect of such matter against Assure or its
      present or former directors, officers, employers, agents or advisors or
      Assure's counsel.

Change of Board Recommendation

The board of directors of Assure reserves the right to not make, withdraw,
redefine, modify or change its recommendations or its determinations referred to
in Section 6.1(u) of the Arrangement Agreement if any of the following occur on
or prior to the Effective Date:

      (a)   GEOCAN shall have breached, or failed to comply with, in any
            material respect, any of its covenants or other obligations under
            the Arrangement Agreement;

                                      31

      (b)   any of the representations and warranties of GEOCAN contained in the
            Arrangement Agreement shall not be true and correct in all material
            respects as of the date of the Arrangement Agreement or shall have
            ceased to be true and correct in any material respect thereafter
            (other than as a result of a breach of the Arrangement Agreement by
            Assure or of the Lockup Agreements by any of the Assure
            Securityholders); or

      (c)   it becomes certain that any of the conditions contained in Sections
            3.1 or 5.1 of the Arrangement Agreement will not be satisfied on or
            before the Effective Date (other than as a result of a breach of
            this Agreement by Assure or of the Lockup Agreements by any of the
            Assure Securityholders who execute and deliver Lockup Agreements)
            and all relevant parties do not agree to waive or modify such
            conditions.


Termination of the Arrangement Agreement

The Arrangement Agreement may, prior to the filing of the Articles of
Arrangement, be terminated by mutual agreement of GEOCAN and Assure without
further action on the part of the Assure Securityholders. Subject to Section
10.4 of the Arrangement Agreement, notwithstanding any other rights contained
herein, GEOCAN may terminate the Arrangement Agreement upon notice to Assure:

      (a)   if the Interim Order has been refused, or if granted, is set aside
            or modified in a manner unacceptable to GEOCAN, acting reasonably,
            on appeal or otherwise;

      (b)   if the Arrangement is not approved by Assure Securityholders in
            accordance with the terms of the Interim Order and all applicable
            laws on or before October 5, 2005, subject to an extension of up to
            20 days pursuant to Section 10.4 of the Arrangement Agreement;

      (c)   if the Final Order has not been granted in form and substance
            satisfactory to GEOCAN, acting reasonably, on or before October 5,
            2005, subject to an extension of up to 20 days pursuant to Section
            10.4 of the Arrangement Agreement or, if issued, has been set aside
            or modified in a manner unacceptable to GEOCAN, acting reasonably,
            on appeal or otherwise;

      (d)   if the Arrangement has not been completed on or before October 6,
            2005, subject to an extension of up to 20 days pursuant to Section
            10.4 of the Arrangement Agreement;

      (e)   if a circumstance giving rise to payment of the GEOCAN Break Fee to
            GEOCAN shall have occurred;

      (f)   if a circumstance giving rise to payment of the Assure Break Fee to
            Assure shall have occurred and such payment shall have been made; or

      (g)   upon any other circumstances hereunder that give rise to a
            termination of the Arrangement Agreement by GEOCAN, including those
            set forth in Sections 4.1 and 5.1 of the Arrangement Agreement.

Subject to Section 10.4 of the Arrangement Agreement, notwithstanding any other
rights contained herein, Assure may terminate the Arrangement Agreement upon
notice to GEOCAN:

            (a)   if the Interim Order has been refused, or if granted, is set
                  aside or modified in a manner unacceptable to Assure, acting
                  reasonably, on appeal or otherwise;

            (b)   if the Arrangement is not approved by Assure Securityholders
                  in accordance with the terms of the Interim Order and all
                  applicable laws on or before October 5, 2005, subject to an
                  extension of up to 20 days pursuant to Section 10.4 of the
                  Arrangement Agreement;

            (c)   if the Final Order has not been granted in form and substance
                  satisfactory to GEOCAN, acting reasonably, on or before
                  October 5, 2005, subject to an extension of up to 20 days
                  pursuant to Section 10.4 of the Arrangement Agreement, or, if
                  issued, has been set aside or modified in a manner
                  unacceptable to Assure, acting reasonably, on appeal or
                  otherwise;

                                      32

            (d)   if the Arrangement has not been completed on or before October
                  6, 2005, subject to an extension of up to 20 days pursuant to
                  Section 10.4 of the Arrangement Agreement;

            (e)   if a circumstance giving rise to the payment of the Assure
                  Break Fee to Assure shall have occurred;

            (f)   if a circumstance giving rise to payment of the GEOCAN Break
                  Fee to GEOCAN shall have occurred and such payment shall have
                  been made; or

            (g)   upon any other circumstances hereunder that give rise to a
                  termination of this agreement by Assure, including those set
                  forth in Sections 3.1 and 5.1 of the Arrangement Agreement.

Each of GEOCAN and Assure will give prompt notice to the other of the
occurrence, or failure to occur, at any time from the date hereof until the
Effective Date, of any event or state of facts which occurrence or failure
would, or would likely to:

                  (i)   cause any of the representations or warranties of either
                        GEOCAN or Assure contained in the Arrangement Agreement
                        to be untrue or inaccurate in any material respect on
                        the date thereof or on the Effective Date; or

                  (ii)  result in the failure to comply with or satisfy any
                        covenant, condition or agreement to be complied with or
                        satisfied, in any material respect, by either GEOCAN or
                        Assure under the Arrangement Agreement on or prior to
                        the Effective Date.

      (a)   Subject to Section 10.4(c) of the Arrangement Agreement, neither
            GEOCAN nor Assure may elect not to complete the transactions
            contemplated hereby pursuant to the non-fulfillment of the
            conditions precedent contained in Articles 3, 4 or 5 or pursuant to
            Section 10.2 or 10.3 of the Arrangement Agreement or any termination
            right arising therefrom and no payments are payable pursuant to
            Section 8.2 or 9.3 of the Arrangement Agreement as a result of such
            election unless promptly and in any event prior to the filing of the
            articles of Arrangement for acceptance by the Registrar, the party
            intending to rely thereon has delivered a written notice (a "Default
            Notice") to the other party specifying in reasonable detail all
            breaches, in any material respect, of covenants, representations and
            warranties or other matters which the party delivering such notice
            is asserting as the basis for the non-fulfillment of the applicable
            condition precedent or termination right, as the case may be.

      (b)   Nothing in this Section 10.4 of the Arrangement Agreement shall
            effect, and no Default Notice shall be required in respect of, (i)
            the right of GEOCAN to receive payment of the GEOCAN Break Fee
            pursuant to Section 9.3 (a) or (b) of the Arrangement Agreement, or
            (ii) the right of either party to terminate the Arrangement
            Agreement for matters arising out of the failure to make appropriate
            disclosure in writing to the other party.

      (c)   If any such Default Notice is delivered, provided that the affected
            party is proceeding diligently to cure such matter and such matter
            is capable of being cured neither party may terminate the
            Arrangement Agreement (if they otherwise have the right to do so)
            until expiration of a period of twenty (20) days from such Default
            Notice and then only if such matter is not cured in all material
            respects. If such Default Notice has been delivered prior to the
            date of the Meeting, such meeting shall be postponed until the
            expiry of such period. If such Default Notice has been delivered
            prior to the making of the application for the Final Order or the
            filing of the Articles of Arrangement with the Registrar, such
            application and such filing shall be postponed until the expiry of
            such period.

                                      33

      (d)   Nothing in this Section 10.4 of the Arrangement Agreement shall give
            either GEOCAN or Assure, as the case may be, any right to terminate
            the Arrangement Agreement in addition to the rights contained in
            Articles 3, 4 or 5 or pursuant to Section 10.2 or 10.3 of the
            Arrangement Agreement or any termination right arising therefrom or
            any right to receive payment of the Assure Break Fee or GEOCAN Break
            Fee except in the circumstances provided in Sections 8.2 and 9.3 of
            the Arrangement Agreement.

If the Arrangement Agreement is validly terminated pursuant to any provision of
the Arrangement Agreement, the parties shall return all materials and copies of
all materials delivered to Assure or GEOCAN, as the case may be, or their agents
and, except for the obligations set forth in Sections 8.2, 9.3, and 10.4 and
Article 11 (which shall survive any termination of the Arrangement Agreement and
continue in full force and effect) of the Arrangement Agreement, no party shall
have any further obligations to any other party hereunder with respect to the
Arrangement Agreement except those incurred prior to termination. Except as
expressly provided herein, nothing herein, (including without limitation the
payment of the GEOCAN Break Fee or the Assure Break Fee) shall relieve any party
from liability for any breach of the Arrangement Agreement.
The exercise by any party of any right of termination hereunder shall be without
prejudice to any other remedy available to such party.

Procedure for the Arrangement to Become Effective

Procedural Steps

      The Arrangement is proposed to be carried out pursuant to Section 193 of
the ABCA. The following procedural steps must be taken in order for the
Arrangement to become effective:

      (a)   the Arrangement must be approved by the Assure Securityholders in
            the manner set forth in the Interim Order;

      (b)   the Court must grant the Final Order approving the Arrangement;

      (c)   all conditions precedent to the Arrangement, as set forth in the
            Arrangement Agreement, must be satisfied or waived by the
            appropriate party; and

      (d)   the Final Order and Articles of Arrangement in the form prescribed
            by the ABCA must be filed with the Registrar.


Securityholder Approvals

      The Interim Order provides that the Arrangement Resolution is required to
be approved by 66 2/3% of all of the votes cast on such resolutions by Assure
Shareholders, Assure Preferred Shareholders and Assure Warrantholders, voting
together as a class, present in person or by proxy at the Meeting such that (a)
each Assure Shareholder and Assure Preferred Shareholder is entitled to one vote
for each Assure Share or Assure Preferred Share held, and (b) each Assure
Warrantholder is entitled to one vote for each Assure Share such holder would be
entitled to receive upon the exercise of the Assure Warrants. See Appendix A to
this Information Circular for the full text of the Arrangement Resolution.

      Notwithstanding the foregoing, the Arrangement Resolution authorizes the
Assure Board, without further notice or approval of the Assure Securityholders,
to amend the Arrangement Agreement or the Plan of Arrangement to the extent
permitted by the Arrangement Agreement and, subject to the terms of the
Arrangement Agreement, not to proceed with the Arrangement. See Appendix A to
this Information Circular for the full text of the Arrangement Resolution.

                                      34

Court Approval


Interim Order

      On August 5, 2005, Assure obtained the Interim Order providing for the
calling and holding of the Meeting and other procedural matters. The Interim
Order is attached as Appendix C to this Information Circular.

Final Order

      Pursuant to the ABCA, the implementation of the Arrangement requires Court
approval. Subject to the terms of the Arrangement Agreement, if the Arrangement
Resolution is approved at the Meeting in the manner required by the Interim
Order, Assure will make application to the Court for the Final Order at the
Court, 611 - 4th Street S.W., Calgary, Alberta on September 7, 2005 at 1:15?p.m.
(Calgary time) or as soon thereafter as counsel may be heard. The Notice of
Petition for the Final Order accompanies this Information Circular. Any Assure
Securityholder or other interested party who wishes to participate or be
represented at the hearing may do so, subject to filing with the Court and
serving on Assure, a Notice of Intention to Appear on or before 4:00 p.m.
(Calgary time) on Thursday, September 1, 2005 together with any evidence or
materials which are to be presented to the Court, setting out Assure
Securityholder's or other interested party's address for service and indicating
whether such Assure Securityholder or other interested party intends to support
or oppose the petition or make submissions. Service of such notice shall be
effected by service by ordinary mail upon the solicitors for Assure: Bennett
Jones LLP, 4500 Bankers Hall East, 855 - 2nd Street S.W., Calgary, Alberta, T2P
4K7, Attention: Mr. Ken Lenz. See "Notice of Petition" in this Information
Circular.

      Assure has been advised by legal counsel, Bennett Jones LLP, that the
Court has broad discretion under the ABCA when making orders with respect to an
arrangement and that the Court, in hearing the application for the Final Order,
will consider, among other things, the fairness of the Arrangement to the Assure
Securityholders (and any other interested party as the Court determines
appropriate). The Court may approve the Arrangement either as proposed or as
amended in any manner the Court may direct, subject to compliance with such
terms and conditions, if any, as the Court may determine appropriate. Either
GEOCAN or Assure may determine not to proceed with the Arrangement in the event
that any amendment ordered by the Court is not satisfactory to it, acting
reasonably.


Regulatory Approvals

      The Arrangement requires approval of certain regulatory authorities. The
Arrangement Agreement provides that these approvals are conditions precedent to
the Arrangement becoming effective. GEOCAN will make application to such
authorities prior to the Effective Date in order to obtain all approvals
required in respect of the Arrangement. There can be no assurance that the
requisite approvals will be granted on a timely basis or on conditions
satisfactory to Assure and GEOCAN.



Timing

      If the Meeting is held as scheduled, is not adjourned, the Arrangement
Resolution is approved and the other conditions are satisfied or waived, Assure
will apply to the Court for the Final Order approving the Arrangement. If the
Final Order is obtained on September 7, 2005 in form and substance satisfactory
to GEOCAN and Assure and all other conditions to the Arrangement are satisfied
or waived, Assure expects the Effective Date of the Arrangement will be
September 8, 2005. GEOCAN and Assure may terminate the Arrangement Agreement in
certain circumstances, in which case the Arrangement will not be completed. See
"Part II - The Arrangement - The Arrangement Agreement - Termination of the
Arrangement Agreement" in this Information Circular.

                                      35

      The Arrangement will become effective upon the acceptance by the Registrar
of the filing of a copy of the Final Order and the Articles of Arrangement.

      Assure's objective is to have the Effective Date occur as soon as
practicable after the Meeting. The Effective Date could be delayed, however, for
a number of reasons, including an objection before the Court in the hearing of
the application for the Final Order. As soon as the Effective Date has been
determined, GEOCAN and Assure will issue a joint press release announcing
completion of the Arrangement.

Fairness Opinion

      The Assure Board retained Haywood Securities as its financial advisor
pursuant to an agreement effective April 21, 2005. Pursuant to this agreement,
Haywood Securities has considered the fairness, from a financial point of view,
of the Arrangement to the Assure Shareholders.

      Haywood Securities acts as a trader and dealer, both as principal and
agent, in major Canadian equity markets and as such may execute transactions on
behalf of clients or on behalf of Assure or its related entities for which it
receives compensation. In addition, as an investment dealer, Haywood Securities
conducts research on securities and may, in the ordinary course of business, be
expected to provide research support and investment advice to its clients on
investment matters pertaining to the resulting entity of the Arrangement.

      There are no commitments or agreements between Haywood Securities and
Assure, GEOCAN or any of their respective associates or affiliates with respect
to future business dealings. However, Haywood Securities may, from time to time
in the future, perform financial advisory or investment banking services for
GEOCAN or its successor(s) or related entities.

      Neither Haywood Securities nor any of its affiliates is an insider,
associate or affiliate (as those terms are defined in the Securities Act
(Alberta)) of GEOCAN or Assure or any of their respective associates or
affiliates. Haywood Securities has not been engaged to provide any financial
advisory services to GEOCAN nor has it participated in any financing involving
GEOCAN or Assure Securityholders or any of their respective associates or
affiliates, within the past two years.



Summary of Fairness Opinion

      In connection with its evaluation of the Arrangement, the Assure Board
received the Fairness Opinion to the effect that, as of the Agreement Date,
based on certain assumptions and considerations summarized therein and based
upon the Exchange Ratio, Haywood Securities views the Arrangement as fair, from
a financial point of view, to the Assure Shareholders.

      The full text of the Fairness Opinion, which sets forth the assumptions
and considerations made, procedures followed, matters considered and limitations
on review undertaken, is attached as Appendix H to this Information Circular.
Assure Securityholders are urged to read the Fairness Opinion in its entirety.
This summary of the Fairness Opinion is qualified in its entirety by reference
to the full text of such opinion.

Recommendation of the Assure Board

         The Assure Board has determined that the Arrangement is in the best
interests of Assure and the Assure Securityholders and is fair to the Assure
Securityholders and, as such, has authorized the submission of the Arrangement
to the Assure Securityholders for approval and to the Court for the Final Order.

                                      36

         In coming to its conclusions and recommendations, the Assure Board
considered, among other things, the following factors:

      (a)   the purpose and benefits of the Arrangement as outlined herein;

      (b)   information concerning the financial condition, results of
            operations, the business plans and prospects of GEOCAN and Assure,
            and the resulting potential for the enhancement of the business
            efficiency, management effectiveness and financial results of the
            combined entity;

      (c)   the advice of Haywood Securities and the fact that Haywood
            Securities is in a position to provide the Fairness Opinion;

      (d)   that the Assure Securityholders who oppose the Arrangement will be
            permitted, subject to compliance with certain conditions, to dissent
            from the Arrangement and will be entitled to be paid the fair value
            for their Assure Shares, Assure Preferred Shares and Assure Warrants
            in accordance with Section 191 of the ABCA, as modified by the
            Interim Order; and

      (e)   that the Arrangement will only become effective if, after hearing
            from all interested parties who choose to appear before it, the
            Court determines that the Arrangement is fair to the Assure
            Securityholders.

      The Assure Boards unanimously recommends that the Assure Securityholders
vote in favour of the Arrangement Resolution.

Interests and Intentions of Directors, Officers, Insiders and Significant
Securityholders in Matters to be Acted Upon

      As of the date hereof, the directors and officers of Assure, as a group,
beneficially own or control, directly or indirectly, or exercise control or
direction over, 504,600 Assure Securities. The directors and officers of Assure
have indicated their intention to vote the Assure Shares and Assure Warrants
beneficially held or controlled by them in favour of the Arrangement. All of the
directors and officers of Assure have entered into the Lockup Agreements
requiring them to vote their Assure Securities in favour of the Arrangement.

      To the knowledge of directors and senior officers of Assure, there are no
material interests of any director or senior officer of Assure or anyone who has
held office as such since the beginning of the last completed financial year or
of any associate or affiliate of any of the foregoing, in any matter to be acted
upon at the Meeting, other than the foregoing and as described elsewhere in this
Information Circular or the Appendices hereto.

Expenses of The Arrangement

      If completed, all out-of-pocket expenses incurred in connection with the
Arrangement, the transactions contemplated thereby, the Meeting and the
preparation and mailing of the Information Circular, including legal and
accounting fees, printing costs, financial advisor fees and all disbursements by
advisors, shall be borne by the party incurring such expenses.

Exchange and Issuance of Share Certificates

      In order for an Assure Shareholder to receive GEOCAN Shares under the
Arrangement, such Assure Shareholder must deposit a properly completed and duly
executed Letter of Transmittal, together with the certificate(s) representing
such Assure Shareholders' Assure Shares, with the Depositary at the address set
forth in the Letter of Transmittal. A Letter of Transmittal will be forwarded to
all Assure Shareholders once the Arrangement has been approved.

      Any use of the mail to transmit the share certificates and Letter of
Transmittal is at the risk of the Assure Shareholders and Assure Warrantholders.
If such documents are mailed, it is recommended that registered mail, with
return receipt requested, properly insured, be used.

                                      37

      Assure Shareholders and Assure Warrantholders who dissent and who
ultimately are not entitled to be paid the fair value of their Assure Shares or
Assure Warrants respectively; will be entitled to receive GEOCAN Shares under
the Arrangement.

      If the Arrangement proceeds, certificates representing the number of
GEOCAN Securities issued to each Assure Securityholder will be, as soon as
practicable following the Effective Date and the receipt by the Depositary of a
properly completed and duly executed Letter of Transmittal:

      (a)   forwarded by, or on behalf of GEOCAN to that Assure Security holder,
            at the address specified in the Letter of Transmittal, by first
            class mail (postage prepaid); or

      (b)   made available at the Depositary for pick up by the holder, if
            requested by the Assure Securityholder in the Letter of Transmittal.

      If a certificate representing Assure Securities has been lost, apparently
destroyed or wrongfully taken, the holder of such shares should immediately
contact the registrar and transfer agent of the Assure Securities, Continental,
so that arrangements can be made to issue a replacement certificate to such
holder upon such holder satisfying such reasonable requirements as may be
imposed by Assure and Continental in that regard.

Failure to Forward Letters of Transmittal and to Deposit Certificates

      Pursuant to the terms of the Plan of Arrangement, any certificates
formerly representing Assure Securities that are not deposited with the
Depositary together with a duly completed Letter of Transmittal and any other
documents the Depositary reasonably requires, on or before the fifth anniversary
of the Effective Date, shall cease to represent a right or claim of any kind or
nature and the GEOCAN Securities to which the holder of such securities was
entitled shall be cancelled.

Stock Exchange Listings

      The Assure Shares are currently quoted on the OTCBB under the symbol
"ASURF" and on the Frankfurt Stock Exchange under the symbol "ASL" (WKN 357954).
On July 8, 2005, the last trading day prior to the initial date of the
announcement of the proposed Arrangement, the closing price of the Assure Shares
on the OTCBB was US$0.71 per share. On August 4, 2005, the closing price of the
Assure Shares on the OTCBB was $1.07.

      The GEOCAN Shares are listed and posted for trading on the TSX under the
symbol "GCA". On July 8, 2005, the last trading day prior to the initial date of
the announcement of the proposed Arrangement, the closing price of the GEOCAN
Shares on the TSX was $1.52 per share. On August 4, 2005, the closing price of
the GEOCAN Shares on the TSX was $1.97.

      It is a condition to the completion of the Arrangement that the TSX shall
have approved the listing of the GEOCAN Shares. Application has been made to
list the GEOCAN Shares issued to the Assure Securityholders on the TSX.

Certain Canadian Federal Income Tax Considerations

      In the opinion of Bennett Jones LLP and Borden Ladner Gervais LLP, the
following is a fair and adequate summary of the principal Canadian federal
income tax considerations under the Income Tax Act in respect of the Arrangement
generally applicable to Assure Shareholders who, for the purposes of the Income
Tax Act and at all relevant times, hold their Assure Shares as capital property,
deal at arm's length with GEOCAN and do not dissent to the Arrangement. Assure
Shares generally will be considered to be capital property to an Assure
Shareholder unless they are held in the course of carrying on a business or are
acquired in a transaction which may be considered to be an adventure in the
nature of trade. Certain Assure Shareholders who are resident in Canada and
whose Assure Shares might not otherwise qualify as capital property may be
entitled to make an irrevocable election in accordance with subsection 39(4) of
the Income Tax Act to have their Assure Shares treated as capital property.

                                      38

      This summary is not applicable to Assure Shareholders: (a) that do not
hold their Assure Shares as capital property; (b) that are "financial
institutions" or "specified financial institutions" (as defined in the Income
Tax Act); (c) an interest in whom would be a "tax shelter investment" (as
defined in the Income Tax Act); (d) who are exempt from tax under Part I of the
Income Tax Act; or (e) that are Dissenting Securityholders. Any such Assure
Shareholders should consult their own tax advisors with respect to the
Arrangement.

      This summary is based upon the current provisions of the Income Tax Act
and counsels' understanding of the current administrative and assessing
practices of the Canada Revenue Agency to the date hereof. This summary assumes
that all specific publicly announced proposals to amend the Income Tax Act and
regulations thereunder announced by or on behalf of the Minister of Finance
(Canada) prior to the date hereof will be enacted as proposed, although there is
no assurance that such proposed amendments will be enacted as proposed, or at
all. This summary does not take into account or anticipate any other changes in
the law, whether by judicial, governmental or legislative action or decision,
nor does it take into account the tax laws of any province, territory or foreign
jurisdiction, any of which may differ significantly from the Canadian federal
income tax considerations described herein.

      This summary is of a general nature only and is not exhaustive of all
Canadian federal income tax considerations. This summary is not intended to be,
and should not be construed to be, legal or tax advice to any Assure
Shareholder. Assure Shareholders should consult their own tax advisors to
determine the particular tax consequences to them of the Arrangement.

Residents of Canada

      This part of the summary is applicable to an Assure Shareholder who is
resident, or deemed to be resident, in Canada for the purposes of the Income Tax
Act.

      Generally, an Assure Shareholder will realize neither a capital gain nor a
capital loss as a result of the exchange of Assure Shares for GEOCAN Shares
provided that: (i) such Assure Shareholder does not include any portion of the
capital gain or capital loss otherwise determined from such exchange in
computing the Assure Shareholder's income, and (ii) immediately after the
exchange, such Assure Shareholder, persons with whom such holder does not deal
at arm's length or the holder together with such persons, does not control
GEOCAN or beneficially own shares of GEOCAN having a fair market value of more
than 50% of the fair market value of all of the outstanding shares of GEOCAN.
The adjusted cost base of an Assure Shareholder's Assure Shares will become the
cost of the GEOCAN Shares received in these circumstances. The cost of such
GEOCAN Shares generally must be averaged with the adjusted cost base of any
other GEOCAN Shares held by such Assure Shareholder to determine the adjusted
cost base of each GEOCAN Share to the holder.

      An Assure Shareholder may choose to file a tax return recognizing a
capital gain or capital loss on the exchange under the Arrangement in such
holder's taxation year which includes the Effective Date. In such event, the
holder will be considered to have disposed of the Assure Shares for GEOCAN
Shares for proceeds of disposition equal to the fair market value of the GEOCAN
Shares received on the exchange. The amount of the capital gain (or capital
loss) will equal the amount that the holder's proceeds of disposition, net of
any reasonable costs of disposition, exceed (or are less than) the adjusted cost
base of that holder's Assure Shares immediately before the exchange. Any Assure
Shareholder that chooses to recognize a capital gain or capital loss will
acquire the GEOCAN Shares at a cost equal to the fair market value of such
GEOCAN Shares received on the exchange. The cost of such GEOCAN Shares must be
averaged with the adjusted cost base of all other GEOCAN Shares held by such
Assure Shareholder to determine the adjusted cost base of each GEOCAN Share to
the holder.

                                      39

      Under the Income Tax Act, one-half of a capital gain must be included in
computing a holder's income as a taxable capital gain. One-half of any capital
loss may be deducted as an allowable capital loss only against taxable capital
gains in computing income in accordance with the provisions of the Income Tax
Act. Allowable capital losses for a taxation year in excess of taxable capital
gains for that year generally may be carried back and deducted in any of the
three preceding taxation years or carried forward and deducted in any subsequent
taxation year against net taxable capital gains realized in such years, to the
extent and in the circumstances provided in the Income Tax Act. The amount of
any such capital loss otherwise determined will, if the Assure Shareholder is a
corporation, be reduced by the amount of dividends or deemed dividends received
on the Assure Shares to the extent and in the circumstances provided in the
Income Tax Act. Similar rules apply to a partnership or a trust of which a
corporation, partnership or trust is a member or beneficiary. Taxable capital
gains of a Canadian-controlled private corporation (as defined in the Income Tax
Act) may be subject to an additional refundable tax at a rate of 6-2/3%. Eighty
percent of any capital gains realized by a holder who is an individual will be
included in computing such individual's liability for alternative minimum tax.

Non-Resident Assure Shareholders

      This portion of the summary is applicable to an Assure Shareholder who is
neither a resident, nor deemed to be a resident, of Canada for the purposes of
the Income Tax Act ("Non-Resident"). Such a holder whose Assure Shares are not
and are not deemed to be "taxable Canadian property" for the purposes of the
Income Tax Act will not be subject to tax under the Income Tax Act on the
exchange of such holder's Assure Shares for GEOCAN Shares under the Arrangement.
A Non-Resident's Assure Shares generally will not be taxable Canadian property
provided: (a) the Non-Resident does not use or hold, and is not deemed to use or
hold, such shares in connection with carrying on a business in Canada; (b) such
shares are not "designated insurance property" of the Non-Resident within the
meaning of the Income Tax Act; (c) the Non-Resident has not, alone or in
combination with persons with whom the Non-Resident does not deal at arm's
length, owned (or had an interest in or option to acquire) 25% or more of the
issued shares of any class or series of the capital stock of Assure at any time
within the 60 month period preceding the exchange; (d) the Assure Shareholder
has not elected under the Income Tax Act to treat such shares as taxable
Canadian property upon ceasing to be a resident of Canada; or (e) the Assure
Shares are not otherwise deemed to be taxable Canadian property of the
Non-Resident under the Income Tax Act. The Canadian income tax consequences to a
Non-Resident who holds Assure Shares that are taxable Canadian property would
generally be the same as those described above for Assure Shareholders who are
residents of Canada.

Right of Dissent

      The following description of the rights of Dissenting Securityholders is
not a comprehensive statement of the procedures to be followed by a Dissenting
Securityholder who seeks payment of the fair value of the securities held by it
and is qualified in its entirety by reference to the full text of the Interim
Order and Section 191 of the ABCA which are attached to this Information
Circular as Appendix C and G, respectively. A Dissenting Securityholder
intending to exercise the Dissent Rights should carefully consider and comply
with the provisions of Section 191 of the ABCA, as modified by the Interim
Order. The statutory provisions covering the Dissent Rights are technical and
complex. Failure to comply with the provisions of Section 191 of the ABCA, as
modified by the Interim Order, and to adhere to the procedures established
therein may result in the loss of all rights thereunder.

      The Court hearing the application for the Final Order has the discretion
to alter the rights of dissent described herein based on the evidence presented
at such hearing.

      Pursuant to the Dissent Rights, a registered Assure Securityholder is
entitled to dissent and be paid the fair value of the securities held by such
Assure Securityholder, determined as of the close of business on the last
Business Day before the day on which the Arrangement Resolution from which such
holder dissents is adopted. A registered Assure Securityholder may dissent only
with respect to all securities held by such registered Assure Securityholder or
on behalf of any one Beneficial Holder and registered in the Dissenting
Securityholder's name. Only registered Assure Securityholders may dissent.
Persons who are Beneficial Holders of Assure Securities registered in the name
of a broker, custodian, nominee or other intermediary who wish to dissent,
should be aware that they may do so only through the registered owner of such
securities. Accordingly, a Beneficial Holder must make arrangements for the
registered holder of his or her Assure Securities to dissent on his or her
behalf. A registered holder, such as a broker, who holds securities as a nominee
for Beneficial Holders, some of whom wish to dissent, must exercise dissent
rights on behalf of such Beneficial Holders with respect to the securities held
for such Beneficial Holders. In such case, the demand for dissent should set
forth the number of securities covered by it. Alternatively, a Beneficial Holder
of Assure Securities desiring to exercise dissent rights may make arrangements
for the Assure Securities beneficially owned by such Beneficial Holder to be
registered in his or her name prior to the time the written objection to the
Arrangement Resolution is required to be received by Assure.

                                      40

      To exercise such right, Assure must receive from the Dissenting
Securityholder a written objection to the Arrangement Resolution, delivered to
Assure, c/o Bennett Jones LLP, 4500 Bankers Hall East, 855 - 2nd Street S.W.,
Calgary, Alberta, T2P 4K7, Attention: Mr. Ken Lenz, by 5:00 p.m. (Calgary time)
two Business Days before the Meeting, and the Dissenting Securityholder must
otherwise comply with Section 191 of the ABCA, as modified by the Interim Order.
An Assure Securityholder wishing to exercise the Dissent Rights with respect to
such holder's securities must abstain from voting the securities held by it in
respect of the Arrangement Resolution.

      A vote against the Arrangement Resolution or an abstention does not
constitute a written objection. If the Arrangement Resolution is adopted, Assure
or the Dissenting Securityholder, where the Dissenting Securityholder has sent
the required written objection, may apply to the Court to fix the fair value of
the Dissenting Securityholder's securities. If the application is made, Assure
is required to send to each Dissenting Securityholder a written offer to pay
such Dissenting Securityholder an amount considered by the directors of Assure
to be the fair value of the Dissenting Securityholder's securities. If such
offer is not made or is not accepted, the Court shall fix the fair value of the
Assure Securities, as applicable. There is no obligation on Assure to apply to
the Court. If an application is made by either party, the Dissenting
Securityholder will be entitled to be paid the amount fixed by the Court for the
securities in respect of which the Dissenting Securityholder dissented. A
Dissenting Securityholder may make an agreement with Assure for the purchase of
such holder's securities in the amount of the offer made by Assure at any time
before the Court pronounces an order fixing the fair value of the applicable
securities.

      A Dissenting Securityholder is not required to give security for costs in
respect of an application and, except in special circumstances, will not be
required to pay the costs of the application or appraisal. On the application,
the Court will make an order fixing the fair value of the securities of all
Dissenting Securityholders who are parties to the application, giving judgment
in that amount against Assure and in favour of each of those Dissenting
Securityholders, and fixing the time within which Assure must pay that amount
payable to the Dissenting Securityholders. The Court may in its discretion allow
a reasonable rate of interest on the amount payable to each Dissenting
Securityholder calculated from the date on which the Dissenting Securityholder
ceases to have any rights as a Assure Securityholder, until the date of payment.

      On the Arrangement becoming effective, or upon the making of an agreement
between Assure and the Dissenting Securityholder as to the payment to be made by
Assure to the Dissenting Securityholder, or upon the pronouncement of a Court
order, whichever first occurs, the Dissenting Securityholder will cease to have
any rights as a Assure Securityholder other than the right to be paid the fair
value of such holder's securities, in the amount agreed to between Assure and
the Dissenting Securityholder or in the amount of the judgment, as the case may
be. Until one of these events occurs, the Dissenting Securityholder may withdraw
their dissent, or Assure may rescind the Arrangement Resolution, and in either
event the dissent and appraisal proceedings in respect of that Dissenting
Securityholder will be discontinued.

      Assure shall not make a payment to a Dissenting Securityholder under
Section 191 if there are reasonable grounds for believing that Assure is or
would after the payment be unable to pay its liabilities as they become due, or
that the realizable value of the assets of Assure would thereby be less than the
aggregate of its liabilities. In such event, Assure shall notify each Dissenting
Securityholder that it is unable lawfully to pay Dissenting Securityholders for
their securities, in which case the Dissenting Securityholder may, by written
notice to Assure within 30 days after receipt of such notice, withdraw such
holder's written objection, in which case Assure shall, subject to the terms of
the Arrangement, be deemed to consent to the withdrawal and such Dissenting
Securityholder shall be reinstated with full rights as a Assure Securityholder
failing which such Dissenting Securityholder retains a status as a claimant
against Assure to be paid as soon as Assure is lawfully entitled to do so or, in
a liquidation, to be ranked subordinate to the rights of creditors of Assure but
in priority to its shareholders.

                                      41


      Assure Securityholders who exercise the Dissent Rights and who:

      (a)   are ultimately entitled to be paid fair value for their securities
            shall be deemed to have transferred such securities to Assure for
            cancellation at the Effective Time; or

      (b)   are ultimately not entitled, for any reason, to be paid fair value
            for their securities shall be deemed to have participated in the
            Arrangement on the same basis as non-dissenting Assure
            Securityholders in accordance with the Plan of Arrangement.

      In no case shall Assure or any other person be required to recognize
Dissenting Securityholders as Assure Securityholders, as applicable, after the
Effective Time.

      Any Assure Securityholder who may wish to exercise the Dissent Rights
should carefully consider and comply with the provisions of the Interim Order
and Section 191 of the ABCA, the full texts of which are set out in Appendix C
and G, respectively, to this Information Circular and consult his or her own
legal advisor.

      It is a condition to the Arrangement that Assure Securityholders of not
more than 10% of the aggregate of the outstanding Assure Shares, Assure
Preferred Shares and Assure Warrants shall have exercised rights of dissent in
respect of the Arrangement.

Other Matters

Resale of GEOCAN Shares

Canada

      The GEOCAN Securities to be issued to Assure Securityholders pursuant to
the Arrangement will be issued in reliance on exemptions from prospectus and
registration requirements of applicable securities laws of the various
applicable provinces in Canada (other than the province of Quebec) and will
generally be "freely tradable" (and not subject to any "restricted period" or
"hold period") if the following conditions are met: (i) the trade is not a
control distribution (as defined in applicable securities legislation); (ii) no
unusual effort is made to prepare the market or to create a demand for the
securities that are the subject of the trade; (iii) no extraordinary commission
or consideration is paid to a person or company in respect of the trade; and
(iv) if the selling shareholder is an insider or an officer of the issuer, the
selling shareholder has no reasonable grounds to believe that the issuer is in
default of securities legislation.

      In Quebec, GEOCAN will apply for and expects to receive orders from the
securities regulatory authority providing exemptions from the prospectus and
registration requirements for the issuance of GEOCAN Securities to Assure
Securityholders resident in the province of Quebec and the subsequent resale of
such GEOCAN Securities.

United States

      The GEOCAN Securities to be issued to Assure Securityholders pursuant to
the Arrangement will not be registered under the U.S. Securities Act, in
reliance upon the exemption from registration provided by Section 3(a)(l0)
thereof. Following the Arrangement, GEOCAN Securities held by any holder who was
not an "affiliate", for purposes of United States federal securities laws, of
Assure, before the Arrangement, and who will not be an affiliate of GEOCAN after
the Arrangement and at the time of any resale of such GEOCAN Securities, may be
resold without restriction under the U.S. Securities Act. Any resale of GEOCAN
Securities by a holder who was such an affiliate before the Arrangement or is
such an affiliate after the Arrangement may be subject to the registration
requirements of the U.S. Securities Act, absent an exemption therefrom. Any such
affiliate (or former affiliate) should obtain the advice of its legal counsel
with respect to the application of the U.S. Securities Act to the offer or sale
of such GEOCAN Securities by such person. For the purposes of the U.S.
Securities Act, an "affiliate" of GEOCAN or Assure is a person that directly, or
indirectly through one or more intermediaries, controls or is controlled by, or
is under common control with, GEOCAN or Assure, as the case may be.

                                      42

      Assure Securityholders residing elsewhere than in Canada are urged to
consult their legal advisers to determine the extent of all applicable resale
provisions.


Legal Developments

      Section 193 of the ABCA provides that, where it is impracticable for a
corporation to effect an arrangement under any other provision of the ABCA, a
corporation may apply to the Court for an order approving the arrangement
proposed by such corporation. Pursuant to this section of the ABCA, such an
application will be made by Assure for approval of the Arrangement. There have
been a number of judicial decisions considering this section and its
application; however, there have not been, to the knowledge of Assure, any
recent significant decisions.

      Assure Securityholders should consult their legal advisers with respect to
the legal rights available to them in relation to the Arrangement.


Legal Matters

      Certain legal matters relating to the Arrangement have been passed upon by
Bennett Jones LLP, on behalf of Assure and by Borden Ladner Gervais LLP, on
behalf of GEOCAN. As at August 2, 2005, the partners and associates of each of
Bennett Jones LLP and Borden Ladner Gervais LLP each beneficially owned,
directly or indirectly, less than 2% of the outstanding GEOCAN Shares. As at
August 2, 2005, the partners and associates of each of Bennett Jones LLP and
Borden Ladner Gervais LLP each beneficially owned, directly or indirectly, less
than 1% of the outstanding Assure Securities.

                                      43


          PART III - INFORMATION RELATING TO GEOCAN, POST-ARRANGEMENT

      At the Effective Time, all of the Assure Shares will be acquired by
GEOCAN, which will continue as "GEOCAN Energy Inc."

Selected Reserves and Operational Information

      It should not be assumed that the estimates of future net revenues
presented in the tables below represent the fair market value of the reserves.
There is no assurance that the constant prices and costs assumptions and
forecast prices and costs assumptions will be attained and variances could be
material. The recovery and reserve estimates of the Corporation's crude oil,
natural gas liquids and natural gas reserves provided herein are estimates only
and there is no guarantee that the estimated reserves will be recovered. Actual
crude oil, natural gas and natural gas liquid reserves may be greater than or
less than the estimates provided herein.

Note:
(1)  All pricing information for constant and forecast prices and costs and
     other pricing assumptions relating to GEOCAN and Assure are included in
     Appendices D and E to this Information Circular, respectively.

(2)  Pro-Forma combined reserves information reflects the combined reserves of
     Assure and GEOCAN. No adjustments have been made to reflect synergies and
     efficiencies resulting from the Arrangement or for Saskatchewan capital tax
     or abandonment costs, neither of which have been applied in the case of
     GEOCAN. Actual reserves information of GEOCAN subsequent to the Arrangement
     may be materially different from these figures. The Assure Securityholders
     are advised to avoid placing undue reliance on these figures.

(3)  Assure disposed of producing properties in the Chestermere area of Alberta
     in early January 2005. Assure's working interest proved and proved plus
     probable reserves as estimated by Sproule for this property as of December
     31, 2004 was 417 Mboe and 659 Mboe, respectively.
(4)  Pro-Forma combined average prices information reflects a weighted average
     percentage of approximately one third Assure and two-thirds GEOCAN. Actual
     prices of GEOCAN subsequent to the Arrangement may be materially different
     from these figures. The Assure Securityholders are advised to avoid placing
     undue reliance on these figures.

      GEOCAN has provided the information contained in this Information Circular
concerning GEOCAN and its businesses, including its financial information and
financial statements. Assure assumes no responsibility for the accuracy or
completeness of such information, nor for any omission on the part of GEOCAN of
facts or events which may affect the accuracy of such information.

Risk Factors

      GEOCAN and Assure are, and GEOCAN will be, subject to certain risks that
should be carefully considered. The risks facing GEOCAN and Assure are set out
in Appendix D and Appendix E, respectively, attached thereto. The following are
risks related specifically to the Arrangement.


The Arrangement is expected to result in benefits to the combined company, but
the combined company may not realize those benefits due to challenges associated
with integrating the companies.

The success of the Arrangement will be dependent in large part on the success of
the management of the combined company in integrating the operations,
technologies and personnel of the two companies following the close of the
Agreement. The failure of the combined company to meet the challenges involved
in successfully integrating the operations of GEOCAN and Assure or otherwise to
realize any of the anticipated benefits of the Agreement, including anticipated
cost savings described in this Information Circular, could seriously harm the
results of operations of the combined company. In addition, the overall
integration of the two companies may result in unanticipated operations
problems, expenses and liabilities and diversion of management's attention. The
challenges involved in this integration include the following:

      o     integrating successfully each company's operations, technologies,
            products and services;

      o     coordinating sales and marketing efforts to effectively communicate
            the capabilities of the combined company;
      o     demonstrating to the customers of GEOCAN and Assure that the
            Arrangement will not result in adverse changes in business focus;

      o     coordinating and rationalizing research and development activities
            to enhance introduction of new products and technologies with
            reduced cost;

      o     preserving distribution, marketing or other important relationships
            of both GEOCAN and Assure and resolving potential conflicts that may
            arise;

      o     assimilating the personnel of both companies and persuading
            employees that the business cultures of both companies are
            compatible;

                                      46


      o     maintaining employee morale and motivation, particularly given
            recent cost reduction initiatives undertaken by both companies, and
            retaining key employees; and

      o     reducing the costs associated with each company's operations.

      GEOCAN and Assure may not be able to successfully integrate their
operations in a timely manner, or at all, and the combined company may not
realize the anticipated benefits or synergies of the Arrangement to the extent
or in the timeframe anticipated. The anticipated benefits and synergies include
cost savings associated with anticipated restructuring efforts and other
operational efficiencies, greater economies of scale and revenue enhancement
opportunities. In addition, GEOCAN anticipates that Assure's cash reserves will
provide the combined company with an increased ability to fund development and
operations. However, these anticipated benefits and synergies are based on
assumptions, not actual experience, and assume a successful integration. Also,
upon completion of the Arrangement, Assure's cash reserves may be significantly
less than anticipated, due to, among other things, the exercise of dissent
rights by Assure Securityholders. The combined company's ability to realize
these benefits and synergies could be adversely impacted to the extent that
GEOCAN's or Assure's relationships with existing or potential customers,
suppliers or strategic partners is adversely affected as a consequence of the
Arrangement, or by practical or legal constraints on its ability to combine
operations or implement workforce reductions.


GEOCAN and Assure expect to incur significant costs associated with the
Arrangement.

      GEOCAN and Assure estimate they could collectively incur direct
transaction costs of approximately $3,000,000 in connection with the Arrangement
GEOCAN's direct transaction costs will be included as a part of the total
purchase cost for accounting purposes. Actual direct transaction costs incurred
in connection with the Arrangement may vary. In addition, GEOCAN will incur
additional costs to the extent that any holders of issued and outstanding Assure
Securities exercise their right to dissent and receive fair value of their
shares.


If the Arrangement is not completed, GEOCAN's and Assure's share prices and
future business and operations could be harmed.

      If the current market prices of GEOCAN Shares and Assure Shares reflect an
assumption that the Arrangement will be completed, the price of their respective
securities may decline if the Arrangement is not completed. Moreover, GEOCAN's
and Assure's costs related to the Arrangement, including legal, accounting and
some of the fees of their financial advisors, must be paid even if the
Arrangement is not completed.

      In addition, if the Arrangement is not completed, GEOCAN and Assure may be
subject to a number of additional material risks, including the following:

      o     either company may forego other opportunities which would have
            otherwise been available had the Arrangement Agreement not been
            executed, including, without limitation, opportunities foregone as a
            result of affirmative and negative covenants made by each company in
            the Arrangement Agreement, such as covenants affecting the conduct
            of each company's business outside the ordinary course of business;
            and

      o     either company may be unable to obtain additional sources of
            financing or conclude another sale, merger or Arrangement on as
            favourable terms, in a timely manner, or a tall.


Fluctuations in the Canadian-U.S. exchange rate will affect the value of GEOCAN
Shares that the Assure Shareholders will receive in the Arrangement.

      The value of GEOCAN Shares that Assure Shareholders will receive in the
Arrangement depends on the Canadian-U.S. exchange rate, as the GEOCAN Shares are
valued in Canadian dollars and Assure Shares are valued in U.S. dollars.


The completion of the Arrangement is subject to the satisfaction of conditions.

                                      47

         The obligations of GEOCAN and Assure to complete the Arrangement are
subject to the satisfaction or waiver, where permissible, of certain conditions
set forth in the Arrangement Agreement. Some of these conditions cannot be
waived, including obtaining the requisite approval of Assure Securityholders,
GEOCAN Securityholders, the Court, relevant Canadian and U.S. securities
regulators and the Toronto Stock Exchange. If these conditions are not
satisfied, the Arrangement will not be completed.


Some of the conditions to the Arrangement may be waived by GEOCAN or Assure
without resoliciting shareholder approval for the Arrangement.

      Some of the conditions set forth in the Arrangement Agreement may be
waived by Assure or GEOCAN, subject to the agreement of the other party in
specific cases. If those conditions are waived, GEOCAN and Assure will evaluate
whether an amendment to the Information Circular and a resolicitation of proxies
is warranted. In the event that the GEOCAN Board or Assure Board determines that
resolicitation of proxies is not warranted, the applicable company will have the
discretion to complete the Arrangement without seeking further shareholder
approval.


Members of the management and board of directors of Assure have interests in the
Arrangement that may present them with actual or potential conflicts of interest
in connection with the Arrangement.

      In considering whether to approve the Arrangement, Assure Securityholders
and GEOCAN Securityholders should recognize that some of the members of
management and board of directors of Assure have interests in the Arrangement
that differ from, or are in addition to, their interests as Assure
Securityholders or GEOCAN Securityholders.

Directors and Officers of GEOCAN

      The following table sets forth the name, municipality of residence and
positions for each of the proposed directors and officers of GEOCAN upon
completion of the Arrangement, together with their principal occupations for the
past five years, and number of GEOCAN Shares owned, directly or indirectly, or
over which control or direction is exercised after giving effect to the
Arrangement. The directors of GEOCAN shall hold office until the next annual
meeting of GEOCAN Shareholders or until their respective successors have been
duly elected or appointed.

            indenture, loan agreement, deed of trust, agreement, lien, contract
            or other material instrument or obligation to which Assure or any
            Assure Subsidiary is a party or to which it, or any of its
            properties or assets, may be subject or by which Assure or any
            Assure Subsidiary is bound, other than a requirement for consent
            from Assure's banker; (ii) violate any judgment, ruling, order,

            would not have any Material Adverse Effect on Assure and the Assure
            Subsidiaries, taken as a whole, or on the ability of Assure to
            consummate the transactions contemplated hereby); or (iii) cause the
            suspension or revocation of any authorization, consent, approval or

            course in connection with or in compliance with the provisions of
            securities laws and any pre merger notification statutes, (i) there
            is no legal impediment to Assure's consummation of the transactions
            contemplated by this Agreement or any agreement contemplated
            hereunder, and (ii) no filing or registration with, or
            authorization, consent or approval of, any domestic or foreign
            public body or authority is necessary by Assure or any Assure
            Subsidiary in connection with the making of this Agreement or the
            consummation of the transactions contemplated by this Agreement or
            any agreement contemplated hereunder, except for such filings or
            registrations which, if not made, or for such authorizations,
            consents or approvals which, if not received, would not have a
            Material Adverse Effect on Assure or any Assure Subsidiary or the
            ability of Assure to consummate the transactions contemplated
            hereby.


                                       10

            8,377,400 Assure Shares are issuable pursuant to outstanding Assure
            Warrants. Except as set forth in the immediately preceding sentence,
            there are no options, warrants or other rights, agreements or
            commitments of any character whatsoever requiring the issuance, sale
            or transfer by Assure of any shares of Assure (including Assure
            Shares) or any securities convertible into, or exchangeable or
            exercisable for, or otherwise evidencing a right to acquire, any
            shares of Assure (including Assure Shares), nor are there any
            outstanding stock appreciation rights, phantom equity or similar
            rights, agreements, arrangements or commitments based upon the book
            value, income or other attribute of Assure. All outstanding Assure
            Shares have been duly authorized and validly issued, are fully paid
            and non assessable and are not subject to, nor were they issued in
            violation of, any pre emptive rights, and all Assure Shares issuable
            upon exercise of the Assure Warrants, in accordance with their terms
            will be duly authorized and validly issued, fully paid and non
            assessable and will not be subject to any pre emptive rights. (f)
            Since December 31, 2004, there has not been any Material Adverse
            Change in respect of Assure and the Assure Subsidiaries, taken as a
            whole.

      (g)   To the best of the knowledge of Assure, all material data and
            information provided by Assure or its agents to GEOCAN and its
            agents and representatives is true and correct in all material
            respects and Assure has not withheld from GEOCAN any material
            information or documents concerning Assure or any Assure Subsidiary
            or its assets or liabilities during the course of GEOCAN's review of
            Assure and its assets and operations.

      (h)   Except (a) as disclosed or reflected in the audited consolidated
            financial statements of Assure as at December 31, 2004 previously
            delivered to GEOCAN, and (b) for liabilities and obligations (i)
            incurred in the ordinary course of business, (ii) pursuant to or in
            connection with the terms of this Agreement, or (iii) as disclosed
            In Writing to GEOCAN, neither Assure nor any Assure Subsidiary has
            incurred any material liabilities of any nature, whether accrued,
            contingent or otherwise or which would be required by generally
            accepted accounting principles applicable in Canada to be reflected
            on a consolidated balance sheet of Assure as of the date hereof.

      (i)   Since December 31, 2004, except as disclosed in the subsequent event
            notes of the Assure Financial Statements, neither Assure nor any
            Assure Subsidiary has taken any action that would be in violation of
            Section 9.1(a) if such provision had been in effect since such date,
            other than violations which would not have any Material Adverse
            Effect on the business, operations or financial condition of Assure
            and the Assure Subsidiaries, taken as a whole, and would not
            materially affect Assure's ability to consummate the transactions
            contemplated hereby.

      (j)   As of their respective dates, the Assure Financial Statements were
            prepared in accordance with generally accepted accounting principles
            applicable in Canada (except as otherwise indicated in such
            financial statements and the notes thereto or, in the related report
            of Assure's independent auditors), and fairly present the financial
            position, results of operations and changes in financial position of
            Assure as of the dates thereof and for the periods indicated
            therein.

      (k)   Assure has no subsidiaries other than the Assure Subsidiaries. Each
            Assure Subsidiary is wholly owned by Assure and no person holds any
            options, warrants or other securities or otherwise has any right to
            acquire any security of an Assure Subsidiary. Assure holds 39% of
            the equity securities of Keantha Holdings Inc.

      (l)   The corporate records and minute books of Assure and each Assure
            Subsidiary are complete and accurate in all material respects.


                                       11


      (m)   To Assure's knowledge, there are no unanimous shareholders
            agreements, voting trusts, escrow agreements or similar agreements
            (other than the Lockup Agreements) among the Assure Shareholders
            relating to Assure or the Assure Shares or other securities of
            Assure.

      (n)   There is no claim, action, proceeding or investigation pending or,
            to the knowledge of Assure, threatened against or relating to Assure
            or any Assure Subsidiary affecting any of its properties or assets
            before any court or governmental or regulatory authority or body
            that, if adversely determined, is likely to have a Material Adverse
            Effect on Assure and the Assure Subsidiaries, take as a whole, or
            prevent or materially delay consummation of the transactions
            contemplated by this Agreement, nor is Assure aware of any basis for
            any such claim, action, proceeding or investigation. Neither Assure
            not any Assure Subsidiary is subject to any outstanding order, writ,
            injunction or decree that has had or is reasonably likely to have a
            Material Adverse Effect on Assure and the Assure Subsidiaries, taken
            as a whole, or prevent or materially delay consummation of the
            transactions contemplated by this Agreement or the Plan of
            Arrangement.

      (o)   Except as has been disclosed In Writing to GEOCAN:

            (i)   Assure and each Assure Subsidiary is not, to the knowledge of
                  Assure, in material violation of any applicable federal,
                  provincial, municipal or local laws, regulations, orders,
                  government decrees or ordinances with respect to
                  environmental, health or safety matters (collectively,
                  "Environmental Laws");

            (ii)  Assure and each Assure Subsidiary has, to the knowledge of
                  Assure, operated its business at all times and has received,
                  handled, used, stored, treated, shipped and disposed of all
                  contaminants without material violation of Environmental Laws
                  which has not been rectified;

            (iii) to the knowledge of Assure, there have been no material
                  spills, releases, deposits or discharges of hazardous or toxic
                  substances, contaminants or wastes which have not been
                  rectified or are in the process of being rectified on any of
                  the real property owned or leased by Assure or any Assure
                  Subsidiary during the period of its ownership or tenure or
                  under its control during the period in which it has had
                  control;

            (iv)  to the knowledge of Assure, there have been no material
                  releases, deposits or discharges, in material violation of
                  Environmental Laws, of any hazardous or toxic substances,
                  contaminants or wastes into the earth, air or into any body of
                  water or any municipal or other sewer or drain water systems
                  by Assure or any Assure Subsidiary which has not been
                  rectified;

            (v)   no material orders, directions or notices have been issued and
                  remain outstanding pursuant to any Environmental Laws relating
                  to the business or assets of Assure and each Assure Subsidiary
                  other than abandonment and similar notices issued in
                  connection with the normal course of business;

            (vi)  Assure and each Assure Subsidiary holds all material licences,
                  permits and approvals required under any Environmental Laws in
                  connection with the operation of its business and the
                  ownership and use of its assets, all such licences, permits
                  and approvals are in full force and effect; and

            (vii) Assure has provided GEOCAN with true and complete copies of
                  all environmental reports, audits and reviews that it or any
                  Assure Subsidiary has in respect of its assets.

      (p)   Neither Assure nor any Assure Subsidiary has received notice of any
            proposed environmental policies or laws which Assure reasonably
            believes would have a Material Adverse Effect on any oil and/or gas
            exploration, development or production operations of Assure and the
            Assure Subsidiaries, taken as a whole, other than those that apply
            to the industry generally.

      (q)   Policies of insurance in force as of the date hereof naming Assure
            or an Assure Subsidiary as an insured adequately cover all risks
            reasonably and prudently foreseeable in the operation and conduct of
            the business of Assure and the Assure Subsidiaries as would be
            customary in respect of the businesses carried on by Assure and the
            Assure Subsidiaries.


                                       12


      (r)   (i)   All Returns required to be filed by or on behalf of Assure and
                  each Assure Subsidiary have been duly filed on a timely basis
                  and such Returns are true, complete and correct in all
                  material respects. All Taxes shown to be payable on the
                  Returns or on subsequent assessments with respect thereto have
                  been paid in full on a timely basis or have been accrued for
                  on Assure's consolidated financial statements, and no other
                  Taxes are payable by Assure or any Assure Subsidiary with
                  respect to items or periods covered by such Returns.

            (ii)  Assure and each Assure Subsidiary has paid or provided
                  adequate accruals in the Assure Financial Statements for
                  Taxes, including income taxes and related future taxes, in
                  conformity with generally accepted accounting principles
                  applicable in Canada.

            (iii) No material deficiencies exist or have been asserted with
                  respect to Taxes of Assure or any Assure Subsidiary. Neither
                  Assure nor any Assure Subsidiary is a party to any action or
                  proceeding for assessment, reassessment or collection of
                  Taxes, nor has such event been asserted or threatened against
                  Assure or any Assure Subsidiary. No waiver or extension of any
                  limitation period is in effect with respect to Taxes or
                  Returns of Assure or any Assure Subsidiary. The Returns of
                  Assure or any Assure Subsidiary have never been audited by a
                  government or taxing authority, nor is any such audit in
                  process, pending or threatened, other than such audits which
                  are no longer outstanding.

            (iv)  Assure and each Assure Subsidiary has withheld from each
                  payment made to any of its officers, directors, and employees
                  and former officers, directors and employees the amount of all
                  Taxes (including, without limitation, income tax) and other
                  deductions required to be withheld therefrom and has paid the
                  same to the proper tax or other authority within the time
                  required under any applicable tax legislation.

      (s)   For all periods since the incorporation of Assure and each Assure
            Subsidiary, GEOCAN has been furnished by Assure with true and
            complete copies of (i) relevant portions of income tax audit
            reports, statements of deficiencies, closing or other agreements
            received by Assure or any Assure Subsidiary or on behalf of Assure
            or any Assure Subsidiary relating to Taxes; and (ii) all federal and
            provincial income or franchise tax returns for Assure and each
            Assure Subsidiary.

            provinces of British Columbia and Alberta, there are more than 50
            beneficial holders of Assure Shares and the Assure Shares are listed
            only on the OTCBB and the Berlin and Frankfurt stock exchanges and
            no other securities of Assure are listed on any stock exchange.

      (u)   The board of directors of Assure has determined that the Arrangement
            is fair to the Assure Shareholders, that the Arrangement is in the
            best interests of Assure and the Assure Shareholders, has
            unanimously approved the Arrangement and the entering into of this
            Agreement and, subject to section 9.3(c) and section 9.4, has
            resolved to unanimously recommend that Assure Securityholders vote
            in favour of the Arrangement.

      (v)   Except for contracts disclosed In Writing to GEOCAN:

            (i)   neither Assure nor any Assure Subsidiary has in effect any
                  bonus plan, commission plan, profit sharing plan, pension
                  plan, royalty plan or arrangement or employee benefit plan for
                  the benefit of any employees, officers, directors or
                  shareholders of Assure or any Assure Subsidiary and it is not
                  a party to any written employment or consulting agreement,

                  other employee benefit obligations of Assure or any Assure
                  Subsidiary arising under or relating to each of the pension or
                  retirement income plans or other employee benefit plans or
                  agreements or policies maintained by or binding on Assure or
                  any Assure Subsidiary as well as for any other payment

      (w)   Except for contracts disclosed In Writing to GEOCAN, neither Assure
            nor any Assure Subsidiary is a party to any employment or management
            agreement or to any written or oral policy, agreement, obligation or
            understanding or any amendment thereto which contains any specific
            agreement as to notice of termination or severance pay in lieu
            thereof or which cannot be terminated without cause on giving
            reasonable notice as may be implied by law.

      (x)   There is not in effect with respect to Assure or any Assure
            Subsidiary, any shareholder rights plan or any other form of plan,

            conducted, except where the failure to so conduct business or be in
            such compliance would not be likely to have a Material Adverse
            Effect on Assure and the Assure Subsidiaries, taken as a whole, and
            none of such licences, registrations or qualifications contains any
            burdensome term, provision, condition or limitation which has or is
            likely to have any Material Adverse Effect on Assure and the Assure
            Subsidiaries, taken as a whole.

      (ee)  Although it does not warrant title, Assure does not have reason to
            believe that it does not have good and marketable title to or the
            irrevocable right to produce and sell its petroleum, natural gas and
            related hydrocarbons (for the purposes of this clause, the foregoing
            are referred to as the "Interests") and does represent and warrant
            that the Interests are free and clear of all liens, charges,
            encumbrances, restrictions or adverse claims created by, through or
            under Assure other than any liens or encumbrances that may be
            outstanding pursuant to credit agreements with Assure's bank, and
            those arising in the ordinary course of business, which are not
            material in the aggregate, and to the knowledge of Assure after due
            inquiry, Assure holds its Interests under valid and subsisting
            leases, licenses, permits, concessions, concession agreements,
            contracts, subleases, reservations or other agreements.


                                       14


      (ff)  Except as disclosed In Writing to GEOCAN, there are no material
            contracts or agreements which have created, or may create, any
            material obligation to Assure or any Assure Subsidiary or from which
            it derives or could derive any material benefit which is required by
            Assure or any Assure Subsidiary to carry on its business as now
            conducted by it or as is now proposed to be carried on by it, except
            those contracts which are in the ordinary course of business, or
            which are reflected in the Assure Financial Statements. For the
            purpose of this representation and warranty, contracts shall be
            deemed to give rise to a material obligation that provides for
            expenditures by Assure or any Assure Subsidiary which aggregate more
            than $250,000 during the next 12 months following the date hereof.

      (gg)  To the best of Assure's knowledge, all ad valorem, property,
            production, severance and similar taxes and assessments based on or
            measured by the ownership of property or the production of petroleum
            substances or the receipts of proceeds therefrom payable by Assure
            or any Assure Subsidiary in respect of any properties or assets up
            to the date hereof and to the Effective Date have been or will be
            properly and fully paid and discharged.

      (hh)  No officer, director, employee or any other person not dealing at
            arm's length with Assure or any Assure Subsidiary, or, to the
            knowledge of Assure, any associate or affiliate of any such person
            or any party owns, has or is entitled to any royalty, net profits
            interest, carried interest or other encumbrances or claims of any
            nature whatsoever which are based on production from Assure's or any
            Assure Subsidiary's properties or assets or any revenue or rights
            attributed thereto.

      (ii)  Except as disclosed In Writing to GEOCAN, there are no material
            contracts or arrangements to which Assure or any Assure Subsidiary
            is a party with any director, officer, employee or any other person
            not dealing at arm's length with Assure or any Assure Subsidiary, or
            any associate or affiliate of any such director, officer, employee
            or any other person not dealing at arm's length with Assure, nor is
            there any material indebtedness owing by Assure or any Assure
            Subsidiary to any such parties or by any such parties to Assure or
            any Assure Subsidiary, other than employment agreements, copies of
            which have previously been provided to GEOCAN.

      (jj)  Except as disclosed In Writing to GEOCAN, or as incurred in the
            ordinary course of business provided they do not give rise to a
            material obligation on the part of Assure or any Assure Subsidiary,
            Assure or any Assure Subsidiary is not a party to or bound by any
            agreement, guarantee, indemnification, or endorsement or like
            commitment of the obligations, liabilities (contingent or otherwise)
            or indebtedness of any person, firm or corporation.

      (kk)  Except as disclosed In Writing to GEOCAN, Assure or any Assure
            Subsidiary has no obligation to incur and renounce in accordance

            31, 2004, made any change in its accounting principles and practices
            as theretofore applied including, without limitation, the basis upon

            Documents as at the date hereof, as relates to Assure and the Assure
            Subsidiaries, are true, correct, and complete and did not contain
            any misrepresentation, as of the respective dates of such
            information or statements, and no material change has occurred in
            relation to Assure and the Assure Subsidiaries which is not
            disclosed in the Assure Public Documents, and Assure has not filed
            any confidential material change reports which continue to be
            confidential.

      (nn)  Except as disclosed in writing to GEOCAN, no securities commission
            or similar regulatory authority or stock exchange in Canada or
            elsewhere has issued any order which is currently outstanding
            preventing or suspending trading in any securities of Assure, no
            such proceeding is, to the knowledge of Assure, pending,
            contemplated or threatened and Assure is not in default in any
            material respect of any requirement of any securities laws, rules or
            policies applicable to Assure or its securities.


                                       15


      (oo)  Assure has delivered to GEOCAN true and current copies of all
            agreements between Assure and its financial advisors in connection
            with the transactions contemplated hereby which could give rise to
            the payment of any fees to such financial advisor, and all
            transaction costs (including legal, financial and other advisors of
            Assure and any other costs and expenses of Assure of the transaction
            contemplated hereby), shall not exceed $850,000.

      (pp)  The aggregate of amounts payable by Assure under any obligations or
            liabilities of Assure to pay any amount to its officers, directors,
            employees or consultants other than for salary and directors' fees
            in the ordinary course, in each case in amounts consistent with
            historic practices and, without limiting the generality of the
            foregoing, including the obligations of Assure to officers,
            employees or consultants for severance, retention, termination or
            bonus payments on the change of control of Assure or on loss of
            position with Assure, will not exceed $610,000, and that $10,000 of
            such amount will be paid, by one or more third parties (at no cost

      (rr)  Assure's oil and gas wells and equipment and facilities are in good
            condition and good working order with such exceptions as do not, in

            operations or financial condition of Assure and the Assure
            Subsidiaries, taken as a whole.

      (ss)  No director, officer, insider or other non-arm's length party is

            to retain full payment at the contract prices therefor.

            Assure Subsidiary, or any person acting on behalf of Assure or any
            Assure Subsidiary, is obligated to sell or deliver any hydrocarbon
            substances allocable to the oil and gas assets of Assure or any

                     GEOCAN'S REPRESENTATIONS AND WARRANTIES

7.1   GEOCAN hereby represents and warrants (and, as applicable, covenants) to
      Assure as follows and acknowledges that Assure is relying upon these
      representations, warranties and covenants in connection with the entering
      into of this Agreement:

      (a)   GEOCAN is a corporation duly incorporated and organized and validly
            existing under the laws of Alberta or, in the case of GEOCAN
            Saskatchewan Inc., Saskatchewan, or, in the case of GEOCAN CZ
            s.r.o., the Czech Republic, and has the requisite corporate power
            and authority to own its properties and conduct its business as such
            business is now conducted or such property is now owned. GEOCAN and
            each GEOCAN Subsidiary is duly registered to do business and in good
            standing in each jurisdiction in which the character of its
            properties, owned or leased, or the nature of its activities make
            such registration necessary, except where the failure to be so
            registered or in good standing would not have a Material Adverse
            Effect on GEOCAN and the GEOCAN Subsidiaries, taken as a whole.

      (b)   GEOCAN has the requisite corporate authority, to enter into this
            Agreement and to carry out its obligations hereunder. The execution
            and delivery of this Agreement and the consummation by GEOCAN of the
            transactions contemplated hereby have been duly authorized by the
            board of directors of GEOCAN and no other proceedings on its part
            are or will be necessary to authorize this Agreement and the
            transactions contemplated hereby. This Agreement has been duly
            executed and delivered by GEOCAN and this Agreement constitutes, the
            legal, valid and binding obligation of GEOCAN enforceable against it
            in accordance with its terms.

      (c)   Except for the approvals contemplated in this Agreement, the
            execution and delivery of this Agreement, by GEOCAN, the
            consummation of the transactions contemplated hereby and compliance
            by GEOCAN with any of the provisions hereof or thereof will not: (i)
            violate, conflict with, or result in a breach of any provision of,
            require any consent, approval or notice under, or constitute a
            default (or an event which, with notice or lapse of time or both,
            would constitute a default) or result in a right of termination or
            acceleration under, or result in a creation of an encumbrance upon
            any of the properties or assets of GEOCAN or any GEOCAN Subsidiary
            under any of the terms, conditions or provisions of (x) the
            constating documents of GEOCAN or any GEOCAN Subsidiary, or (y) any
            note, bond, mortgage, indenture, loan agreement, deed of trust,
            agreement, lien, contract or other material instrument or obligation
            to which GEOCAN or any GEOCAN Subsidiary is a party or to which it,
            or any of its properties or assets, may be subject or by which
            GEOCAN or any GEOCAN Subsidiary is bound, other than a requirement
            for consent from GEOCAN's banker; (ii) violate any judgement,
            ruling, order, writ, injunction, determination, award, decree,
            statute, ordinance, rule or regulation applicable to GEOCAN or any
            GEOCAN Subsidiary; (except, in the case of each of clauses (i) or
            (ii) above, for such violations, conflicts, breaches, defaults,
            terminations, suspensions or revocations which, or any consents,
            approvals or notices which if not given or received, would not
            materially and adversely affect the ability of GEOCAN to consummate
            the transactions contemplated hereby or the benefits to be received
            by the Assure Securityholders pursuant to the transactions
            contemplated hereby); or (iii) cause the suspension or revocation of
            any authorization, consent, approval or license of GEOCAN or (iii)
            cause the suspension or revocation of any authorization, consent,
            approval or license of GEOCAN currently in effect which would have a
            Material Adverse Effect on GEOCAN and the GEOCAN Subsidiaries, taken
            as a whole.

      (d)   Except for the approvals contemplated in this Agreement and
            approvals that have been obtained and other than in connection with
            or in compliance with the provisions of securities laws, the rules
            of the TSX and any pre merger notification statutes, (i) there is no
            legal impediment to GEOCAN's consummation of the transactions
            contemplated by this Agreement or any agreements contemplated
            hereunder and (ii) no filing or registration with, or authorization,
            consent or approval of, any domestic or foreign public body or
            authority is necessary by GEOCAN or any GEOCAN Subsidiary in
            connection with the making of this Agreement or the consummation of
            the transactions contemplated by this Agreement or any agreement
            contemplated hereunder, except for such filings or registrations
            which, if not made, or for such authorizations, consents or
            approvals which, if not received, would not have a Material Adverse
            Effect on GEOCAN and the GEOCAN Subsidiaries taken as a whole or the
            ability to GEOCAN to consummate the transactions contemplated
            hereby.


                                       17


      (e)   As of the date hereof (i) the authorized share capital of GEOCAN

            there are no options, warrants or other rights, agreements or
            commitments of any character whatsoever requiring the issuance, sale
            or transfer by GEOCAN of any shares of GEOCAN (including GEOCAN
            Shares) or any securities convertible into, or exchangeable or
            exercisable for, or otherwise evidencing a right to acquire, any
            shares of GEOCAN (including GEOCAN Shares), nor are there any
            outstanding stock appreciation rights, phantom equity or similar
            rights, agreements, arrangements or commitments based upon the book
            value, income or other attribute of GEOCAN. All outstanding GEOCAN
            Shares have been duly authorized and validly issued, are fully paid
            and non assessable and are not subject to, nor were they issued in
            violation of, any pre emptive rights, and all GEOCAN Shares issuable
            upon exercise, in accordance with their respective terms of GEOCAN
            Options or GEOCAN Warrants will be duly authorized and validly

            pre emptive rights.

            Change in respect of GEOCAN and the GEOCAN Subsidiaries, taken as a
            whole.

      (g)   To the best of the knowledge of GEOCAN, all material data and
            information provided by GEOCAN or its agents to Assure and its
            agents and representatives is true and correct in all material
            respects and GEOCAN has not withheld from Assure any material
            information or documents concerning GEOCAN or any GEOCAN Subsidiary
            or its assets or liabilities during the course of Assure's review of
            GEOCAN and its assets and operations.

      (h)   Except (a) as disclosed or reflected in the audited consolidated
            financial statements of GEOCAN as at December 31, 2004 previously
            delivered to Assure, and (b) for liabilities and obligations (i)
            incurred in the ordinary course of business, (ii) pursuant to or in
            connection with the terms of this Agreement, or (iii) as disclosed
            In Writing to Assure, neither GEOCAN nor any GEOCAN Subsidiary has
            incurred any material liabilities of any nature, whether accrued,
            contingent or otherwise or which would be required by generally
            accepted accounting principles applicable in Canada to be reflected
            on a consolidated balance sheet of GEOCAN as of the date hereof.

      (i)   Since December 31, 2004, except as disclosed in the subsequent event
            notes of the GEOCAN Financial Statements, neither GEOCAN nor any
            GEOCAN Subsidiary has taken any action that would be in violation of
            Section 8.1(a) if such provision had been in effect since such date,
            other than violations which would not have any Material Adverse
            Effect on the business, operations or financial condition of GEOCAN
            and the GEOCAN Subsidiaries, taken as a whole and would not
            materially affect GEOCAN's ability to consummate the transactions
            contemplated hereby.

      (j)   As of their respective dates, the GEOCAN Financial Statements were
            prepared in accordance with generally accepted accounting principles
            applicable in Canada (except as otherwise indicated in such
            financial statements and the notes thereto or, in the related report
            of GEOCAN's independent auditors), and fairly present the financial
            position, results of operations and changes in financial position of
            GEOCAN as of the dates thereof and for the periods indicated
            therein.

      (k)   GEOCAN has no subsidiaries other than the GEOCAN Subsidiaries. Each
            GEOCAN Subsidiary is wholly owned by GEOCAN and no person holds any
            options, warrants or other securities or otherwise has any right to
            acquire any security of any GEOCAN Subsidiary.


                                       18

            Subsidiary are complete and accurate in all material respects.

      (m)   To GEOCAN's knowledge, there are no unanimous shareholders
            agreements, voting trusts, escrow agreements or similar agreements
            among the GEOCAN Shareholders relating to GEOCAN or the GEOCAN
            Shares or other securities of GEOCAN.

      (n)   There is no claim, action, proceeding or investigation pending or,
            to the knowledge of GEOCAN, threatened against or relating to GEOCAN
            or any GEOCAN Subsidiary affecting any of its properties or assets
            before any court or governmental or regulatory authority or body
            that, if adversely determined, is likely to have a Material Adverse
            Effect on GEOCAN and the GEOCAN Subsidiaries, taken as a whole, or
            prevent or materially delay consummation of the transactions
            contemplated by this Agreement, nor is GEOCAN aware of any basis for
            any such claim, action, proceeding or investigation. Neither GEOCAN
            nor any GEOCAN Subsidiary is subject to any outstanding order, writ,
            injunction or decree that has had or is reasonably likely to have a
            Material Adverse Effect on GEOCAN and the GEOCAN Subsidiaries, taken
            as a whole, or prevent or materially delay consummation of the
            transactions contemplated by this Agreement or the Plan of
            Arrangement.

                  "Environmental Laws");

            (ii)  GEOCAN and each GEOCAN Subsidiary has, to the knowledge of
                  GEOCAN, operated its business at all times and has received,
                  handled, used, stored, treated, shipped and disposed of all
                  contaminants without material violation of Environmental Laws
                  which has not been rectified;

            (iii) to the knowledge of GEOCAN, there have been no material
                  spills, releases, deposits or discharges of hazardous or toxic
                  substances, contaminants or wastes which have not been
                  rectified or are in the process of being rectified on any of
                  the real property owned or leased by GEOCAN or any GEOCAN
                  Subsidiary during the period of its ownership or tenure or

                  control;

            (iv)  to the knowledge of GEOCAN, there have been no material
                  releases, deposits or discharges, in material violation of
                  Environmental Laws, of any hazardous or toxic substances,
                  contaminants or wastes into the earth, air or into any body of
                  water or any municipal or other sewer or drain water systems
                  by GEOCAN or any GEOCAN Subsidiary which has not been
                  rectified;

            (v)   no material orders, directions or notices have been issued and
                  remain outstanding pursuant to any Environmental Laws relating
                  to the business or assets of GEOCAN and each GEOCAN Subsidiary
                  other than abandonment and similar notices issued in
                  connection with the normal course of business;

            (vi)  GEOCAN and each GEOCAN Subsidiary holds all material licences,
                  permits and approvals required under any Environmental Laws in
                  connection with the operation of its business and the
                  ownership and use of its assets, all such licences, permits

      (p)   Neither GEOCAN nor any GEOCAN Subsidiary has received notice of any
            proposed environmental policies or laws which GEOCAN reasonably
            believes would have a Material Adverse Effect on any oil and/or gas
            exploration, development or production operations of GEOCAN and the
            GEOCAN Subsidiaries, taken as a whole, other than those that apply
            to the industry generally.


                                       19


      (q)   Policies of insurance in force as of the date hereof naming GEOCAN
            or a GEOCAN Subsidiary as an insured adequately cover all risks
            reasonably and prudently foreseeable in the operation and conduct of
            the business of GEOCAN and the GEOCAN Subsidiaries as would be
            customary in respect of the businesses carried on by GEOCAN and the
            GEOCAN Subsidiaries. All such policies of insurance shall remain in
            force and effect and shall not be cancelled or otherwise terminated
            as a result of the transactions contemplated hereby and in the event
            such policies expire pursuant to their terms, GEOCAN will use
            reasonable commercial efforts to renew such insurance for at least
            such period of time as is necessary to have adequate insurance until
            after the Effective Date.

      (r)   (i)   All Returns required to be filed by or on behalf of GEOCAN and
                  each GEOCAN Subsidiary have been duly filed on a timely basis
                  and such Returns are true, complete and correct in all
                  material respects. All Taxes shown to be payable on the
                  Returns or on subsequent assessments with respect thereto have
                  been paid in full on a timely basis or have been accrued for
                  on GEOCAN's consolidated financial statements, and no other
                  Taxes are payable by GEOCAN or any GEOCAN Subsidiary with
                  respect to items or periods covered by such Returns.

            (ii)  GEOCAN and each GEOCAN Subsidiary has paid or provided
                  adequate accruals in the GEOCAN Financial Statements for
                  Taxes, including income taxes and related future taxes, in
                  conformity with generally accepted accounting principles
                  applicable in Canada.

            (iii) No material deficiencies exist or have been asserted with
                  respect to Taxes of GEOCAN or any GEOCAN Subsidiary. Neither
                  GEOCAN nor any GEOCAN Subsidiary is a party to any action or
                  proceeding for assessment, reassessment or collection of
                  Taxes, nor has such event been asserted or threatened against
                  GEOCAN or any GEOCAN Subsidiary. No waiver or extension of any
                  limitation period is in effect with respect to Taxes or
                  Returns of GEOCAN or any GEOCAN Subsidiary. The Returns of
                  GEOCAN or any GEOCAN Subsidiary have never been audited by a
                  government or taxing authority, nor is any such audit in
                  process, pending or threatened, other than such audits which
                  are no longer outstanding.

            (iv)  GEOCAN and each GEOCAN Subsidiary has withheld from each
                  payment made to any of its officers, directors, and employees
                  and former officers, directors and employees the amount of all
                  taxes (including, without limitation, income tax) and other
                  deductions required to be withheld therefrom and has paid the
                  same to the proper tax or other authority within the time
                  required under any applicable tax legislation.

      (s)   For all periods since the incorporation of GEOCAN and each GEOCAN
            Subsidiary, Assure has been furnished by GEOCAN with true and
            complete copies of (i) relevant portions of income tax audit
            reports, statements of deficiencies, closing or other agreements
            received by GEOCAN or any GEOCAN Subsidiary or on behalf of GEOCAN
            or any GEOCAN Subsidiary relating to Taxes; and (ii) all federal and
            provincial income or franchise tax returns for GEOCAN and each
            GEOCAN Subsidiary.

      (t)   GEOCAN is a "reporting issuer", or the equivalent thereof, in the
            provinces of British Columbia, Alberta and Ontario and is in
            material compliance with all the securities laws of such provinces
            and the GEOCAN Shares are listed on the TSX and no other securities
            of GEOCAN are listed on any stock exchange.

      (u)   Except as expressly provided herein, the execution, delivery and
            performance of this Agreement does not and will not result in the
            restriction of GEOCAN or any GEOCAN Subsidiary from engaging in its
            businesses or from competing with any person or in any geographical
            area.

      (v)   As at December 31 2004, GEOCAN's and each GEOCAN Subsidiary's
            Canadian and Alberta Tax Pools were as disclosed to Assure In
            Writing.


                                       20


      (w)   GEOCAN and each GEOCAN Subsidiary has conducted and is conducting
            its business substantially in accordance with good oilfield
            practices and in compliance in all material respects with all
            applicable laws, rules and regulations and, in particular, all
            applicable licensing and environmental legislation, regulations or
            by-laws or other requirements of any governmental or regulatory
            bodies applicable to GEOCAN and each GEOCAN Subsidiary in each
            jurisdiction in which it carries on business and holds all licences,
            registrations and qualifications material to its business and assets
            in all jurisdictions in which it carries on business as now
            conducted, except where the failure to so conduct business or be in
            such compliance would not be likely to have a Material Adverse
            Effect on GEOCAN and the GEOCAN Subsidiaries, taken as a whole and
            none of such licences, registrations or qualifications contains any
            burdensome term, provision, condition or limitation which has or is
            likely to have any Material Adverse Effect on GEOCAN and the GEOCAN
            Subsidiaries, taken as a whole.

      (x)   Although it does not warrant title, GEOCAN does not have reason to
            believe that it does not have good and marketable title to or the
            irrevocable right to produce and sell its petroleum, natural gas and
            related hydrocarbons (for the purposes of this clause, the foregoing
            are referred to as the "Interests") and does represent and warrant
            that the Interests are free and clear of all liens, charges,
            encumbrances, restrictions or adverse claims crated by, through or
            under GEOCAN other than any liens or encumbrances that may be
            outstanding pursuant to credit agreements with GEOCAN's bank, and
            those arising in the ordinary course of business, which are not
            material in the aggregate, and to the knowledge of GEOCAN after due
            inquiry, GEOCAN holds its Interests under valid and subsisting
            leases, licenses, permits, concessions, concession agreements,
            contracts, subleases, reservations or other agreements.

      (y)   To the knowledge of GEOCAN, GEOCAN and each GEOCAN Subsidiary has
            all agreements, permits, licences, approvals, certificates and other
            rights and authorizations material to the conduct of GEOCAN's and
            each GEOCAN Subsidiary's business and, to the knowledge of GEOCAN,
            all such agreements, permits, licences, approvals, certificates and
            other rights and authorizations possessed by GEOCAN and each GEOCAN
            Subsidiary are valid and subsisting and GEOCAN and each GEOCAN
            Subsidiary is not in material default under any such agreements,
            permits, licences, approvals, certificates and other rights and
            authorizations, except where such invalidity or default would not,
            in the aggregate, have a Material Adverse Effect on GEOCAN and the
            GEOCAN Subsidiaries, taken as a whole.

      (z)   Except as disclosed in the consolidated financial statements
            (including the notes thereto) of GEOCAN for the first financial
            quarters of the 2005 financial year, GEOCAN has not, since December
            31, 2004, made any change in its accounting principles and practices
            as theretofore applied including, without limitation, the basis upon
            which its assets and liabilities are recorded on its books and its
            earnings and profits and losses are ascertained.

      (aa)  GEOCAN and each GEOCAN Subsidiary is not:

            (i)   in breach or violation of any term or provision of, or in
                  default under any agreement, instrument, licence, permit or
                  authority to which it is a party or by which it is bound and
                  which is material to it; or

            (ii)  in violation or contravention of any provision of any law or
                  regulation or any judicial or administrative award, judgment
                  or decree applicable and known to it (after due inquiry);

            except to the extent that such breach, violation or contravention
            would not have a Material Adverse Effect on GEOCAN and the GEOCAN
            Subsidiaries, taken as a whole, or could not reasonably be expected
            to prevent or hinder the consummation of the transactions
            contemplated by this Agreement or the Arrangement.

      (bb)  The information and statements set forth in the GEOCAN Public
            Documents as at the date hereof, as relates to GEOCAN and the GEOCAN
            Subsidiaries, are true, correct, and complete and did not contain
            any misrepresentation, as of the respective dates of such
            information or statements, and no material change has occurred in
            relation to GEOCAN and the GEOCAN Subsidiaries which is not
            disclosed in the GEOCAN Public Documents, and GEOCAN has not filed
            any confidential material change reports which continue to be
            confidential.


                                       21


      (cc)  No securities commission or similar regulatory authority or stock
            exchange in Canada or elsewhere has issued any order which is
            currently outstanding preventing or suspending trading in any
            securities of GEOCAN, no such proceeding is, to the knowledge of
            GEOCAN, pending, contemplated or threatened and GEOCAN is not in
            default of any requirement of any securities laws, rules or policies
            applicable to GEOCAN or its securities.

      (dd)  GEOCAN's oil and gas wells and equipment and facilities are in good
            condition and good working order with such exceptions as do not, in
            the aggregate, have a material adverse effect on the business,
            operations or financial condition of GEOCAN and the GEOCAN
            Subsidiaries, taken as a whole.

      (ee)  Computershare Trust Company of Canada at its office in the city of
            Calgary is the duly appointed registrar and transfer agent of GEOCAN
            with respect to the GEOCAN Shares.

      (ff)  The form of share certificate for the GEOCAN Shares has been
            approved by the board of directors of GEOCAN.

      (gg)  Except as disclosed In Writing to Assure, there are no material
            contracts or agreements which have created, or may create, any
            material obligation to GEOCAN or any GEOCAN Subsidiary or from which
            it derives or could derive any material benefit which is required by
            GEOCAN or any GEOCAN Subsidiary to carry on its business as now
            conducted by it or as is now proposed to be carried on by it, except
            those contracts which are in the ordinary course of business, or
            which are reflected in the GEOCAN Financial Statements. For the
            purpose of this representation and warranty, contracts shall be
            deemed to give rise to a material obligation that provides for
            expenditures by GEOCAN or any GEOCAN Subsidiary which aggregate more
            than $250,000 during the next 12 months following the date hereof.

      (hh)  To the best of GEOCAN's knowledge, all ad valorem, property,
            production, severance and similar taxes and assessments based on or
            measured by the ownership of property or the production of petroleum
            substances or the receipts of proceeds therefrom payable by GEOCAN
            or any GEOCAN Subsidiary in respect of any properties or assets up
            to the date hereof and to the Effective Date have been or will be
            properly and fully paid and discharged.

      (ii)  No officer, director, employee or any other person not dealing at
            arm's length with GEOCAN or any GEOCAN Subsidiary, or, to the
            knowledge of GEOCAN, any associate or affiliate of any such person
            or any party owns, has or is entitled to any royalty, net profits
            interest, carried interest or other encumbrances or claims of any
            nature whatsoever which are based on production from GEOCAN's or any
            GEOCAN Subsidiary's properties or assets or any revenue or rights
            attributed thereto.

      (jj)  Except as disclosed In Writing to Assure, there are no material
            contracts or arrangements to which GEOCAN or any GEOCAN Subsidiary
            is a party with any director, officer, employee or any other person
            not dealing at arm's length with GEOCAN or any GEOCAN Subsidiary, or
            any associate or affiliate of any such director, officer, employee
            or any other person not dealing at arm's length with GEOCAN, nor is
            there any material indebtedness owing by GEOCAN or any GEOCAN
            Subsidiary to any such parties or by any such parties to GEOCAN or
            any GEOCAN Subsidiary, other than employment agreements, copies of
            which have previously been provided to Assure.

      (kk)  Except as disclosed In Writing to Assure or as incurred in the
            ordinary course of business provided they do not give rise to a
            material obligation on the part of GEOCAN or any GEOCAN Subsidiary,
            GEOCAN or any GEOCAN Subsidiary is not a party to or bound by any
            agreement, guarantee, indemnification, or endorsement or like
            commitment of the obligations, liabilities (contingent or otherwise)
            or indebtedness of any person, firm or corporation.

      (ll)  GEOCAN's average daily production for the month of May 2005 was not
            less than 1,575 barrels of oil and liquids per day and 1.9 Mmcf of
            natural gas per day and GEOCAN's average daily production for the
            three months ended March 31, 2005 was 1,915 barrels of oil and
            liquids per day and 1.7 Mmcf per day of natural gas and there has
            been no material adverse change (other than due to short-term plant
            shutdowns) to such production levels since March 31, 2005.

      (mm)  GEOCAN's oil and gas wells and equipment and facilities are in good
            condition and good working order with such exceptions as do not, in
            the aggregate, have a material adverse effect on the business,
            operations or financial condition of GEOCAN and the GEOCAN
            Subsidiaries, taken as a whole.

      (nn)  No director, officer, insider or other non-arm's length party is

            received from GEOCAN's current auditor or any previous auditor since
            its incorporation.

      (pp)  None of GEOCAN, any GEOCAN Subsidiary or any party acting on behalf
            of GEOCAN or any GEOCAN Subsidiary is obligated to deliver any

            party without in due course thereafter receiving and being entitled
            to retain full payment at the contract prices therefor.

      (qq)  There are no production sales contracts, gas balancing agreements,
            arrangements, physical or financial hedges under which GEOCAN or any
            GEOCAN Subsidiary, or any person acting on behalf of GEOCAN or any
            GEOCAN Subsidiary, is obligated to sell or deliver any hydrocarbon
            substances allocable to the oil and gas assets of GEOCAN or any
            GEOCAN Subsidiary to any person, other than contracts that are
            terminable by GEOCAN or any GEOCAN Subsidiary on not more than one
            month's notice.

      (rr)  There is not in effect with respect to GEOCAN or any GEOCAN
            Subsidiary, any shareholder rights plan or any other form of plan,
            agreement, contract or instrument that will trigger any rights to
            acquire GEOCAN Shares or other securities of GEOCAN or any GEOCAN
            Subsidiary or rights, entitlements or privileges in favour of any
            person upon the entering into of this Agreement or on the
            Arrangement becoming effective.

      (ss)  Neither GEOCAN nor any GEOCAN Subsidiary has waived or released the
            applicability of any "standstill" or other provisions of any

                  communications indicating that the same may be contemplated);

      (m)   GEOCAN shall promptly notify Assure in writing of any material
            change (actual, anticipated, contemplated or, to the knowledge of
            GEOCAN, threatened, financial or otherwise) in the business,
            operations, affairs, assets, capitalization, financial condition,

            whether contractual or otherwise, of GEOCAN and the GEOCAN
            Subsidiaries, taken as a whole, or of any change in any
            representation or warranty provided by GEOCAN in this Agreement
            which change is or may be of such a nature to render any
            representation or warranty misleading or untrue in any material
            respect and GEOCAN shall in good faith discuss with Assure any
            change in circumstances (actual, anticipated, contemplated, or to
            the knowledge of GEOCAN threatened) which is of such a nature that
            there may be a reasonable question as to whether notice needs to be
            given to Assure pursuant to this provision;


                                       25


      (n)   GEOCAN will, within two Business Days of GEOCAN receiving any
            written audit inquiry, assessment, reassessment, confirmation or
            variation of an assessment, indication that tax assessment is being
            considered, request for filing of a waiver or extension of time or
            any other notice in writing relating to taxes, interest, penalties,
            losses or tax pools (an "Assessment"), deliver to Assure a copy
            thereof together with a statement setting out, to the extent then
            determinable, an estimate of the obligations, if any, of GEOCAN on
            the assumption that such Assessment is valid and binding; and

      (o)   GEOCAN will use its reasonable commercial efforts to appoint to its

8.2   Subject to Section 10.4, if at any time after the date of this Agreement,
      GEOCAN shall have breached, or failed to comply with, in any material
      respect, any of its covenants or other obligations under this Agreement or
      any of the representations and warranties of GEOCAN contained in this
      Agreement shall not be true and correct in all material respects as of the
      date of this Agreement, except where the failure of such representations
      and warranties to be true and correct would not have a Material Adverse
      Effect on GEOCAN, or shall have ceased to be true and correct in any
      material respect thereafter, except where the failure of such
      representations and warranties to be true and correct would not have a
      Material Adverse Effect on GEOCAN, (other than, in either case, as a
      direct result of and in direct response to a breach by Assure of its
      obligations under this Agreement), then GEOCAN shall, within two business
      days after the first to occur of the events described above, pay to Assure
      the Assure Break Fee. Such payment shall be made in immediately available
      funds to an account designated by Assure. The payment of the Assure Break
      Fee to Assure shall represent full and final settlement of all claims of
      Assure arising in respect of the matter giving rise to such payment and
      Assure shall have no further remedy or recourse in respect of such matter
      against GEOCAN or its present or former directors, officers, employees,
      agents or advisors or GEOCAN's counsel.

                  reclassification items;

      (f)   Assure will use its reasonable commercial efforts to fulfil or cause
            the fulfillment of the conditions set forth in Sections 4.1 and 5.1
            as soon as reasonably possible to the extent the fulfillment of the
            same is within the control of Assure;

      (g)   Assure will make available and cause to be made available to GEOCAN,
            its agents and advisors, as GEOCAN may reasonably request, all
            documents and agreements (including without limitation, any
            correspondence between Assure and its advisors or any governmental
            body and all minute books) and shall allow GEOCAN's officers,
            employees, accountants and other authorized representatives and
            advisors complete access to Assure's properties, premises, field
            operations, records, computer systems, management personnel and
            employees in any way relating to or affecting the business of
            Assure, or the business, operations, prospects, affairs or financial
            status of Assure and shall provide GEOCAN with such other documents
            or agreements as may reasonably be requested by GEOCAN to permit
            GEOCAN to be in a position to expeditiously integrate the business
            and operations of Assure with GEOCAN upon the Arrangement becoming
            effective, except where Assure is contractually precluded from
            making such document or agreement available, and cooperate with
            GEOCAN in securing access for GEOCAN to any such documentation not
            in the possession or under the control of Assure. Assure shall keep
            GEOCAN fully apprised in a timely manner of every circumstance,
            action, occurrence or event occurring or arising in the period
            between the date hereof and the Effective Date that would be
            relevant and material to a purchaser of the Assure Shares or a
            prudent operator of the business and operations of Assure, taken as
            a whole;

      (h)   Assure will as soon as reasonably practicable file, proceed with and
            diligently prosecute an application to the Court under the ABCA for
            an Interim Order of the Court with respect to the matters pertaining
            to the Arrangement and acceptable to GEOCAN, acting reasonably;

      (i)   Assure will seek the Interim Order, which shall provide that for the
            purpose of the Assure Meeting:

            (i)   the securities of Assure for which the holders shall be
                  entitled to vote on the Arrangement shall be the Assure
                  Shares;

            (ii)  the requisite majority for the approval of the Arrangement by
                  the Assure Securityholders shall be two thirds of the votes
                  cast by the Assure Securityholders present in person or by
                  proxy at the Assure Meeting,

            provided that in the event that counsel to Assure and counsel to
            GEOCAN advise that it is appropriate to establish such other class
            or classes of securities to vote on the Arrangement, then Assure and
            GEOCAN shall, acting reasonably, agree to amend the Plan of
            Arrangement as may be necessary;

      (j)   Assure will:

            (i)   forthwith carry out the terms of the Interim Order to the
                  extent applicable to it;


                                       28


            (ii)  convene the Assure Meeting and distribute copies of this
                  Agreement (or a written summary thereof prepared by Assure in
                  form and substance reasonably satisfactory to GEOCAN), in each
                  case as ordered by the Interim Order;

            (iii) solicit proxies to be voted at the Assure Meeting in favour of
                  the Arrangement;

            (iv)  provide notice to GEOCAN of the Assure Meeting and allow
                  GEOCAN's representatives to attend the Assure Meeting; and

            (v)   conduct the Assure Meeting in accordance with the Interim
                  Order, the bylaws of Assure and any instrument governing such
                  Assure Meeting, as applicable, and as otherwise required by
                  law;

      (k)   Assure will, subject to compliance with the terms and conditions
            contained in this Agreement and the approval of the Arrangement in
            accordance with the provisions of the Interim Order, forthwith file,
            proceed with and diligently prosecute an application for the Final
            Order, and will carry out the terms of the Final Order to the extent
            applicable to Assure and will file Articles of Arrangement and the
            Final Order with the Registrar;

      (l)   Assure will prepare (in consultation with GEOCAN), file and
            distribute to the Assure Shareholders in a timely and expeditious
            manner the Information Circular and any amendments or supplements to
            the Information Circular, a letter of transmittal and all other
            related proxy material, all as required by applicable law in all
            jurisdictions where the same is required complying in all material
            respects with all applicable legal requirements on the date of issue
            thereof. Without limiting the generality of the foregoing, Assure
            will ensure that the Information Circular provides Assure
            Securityholders with information in sufficient detail to permit them
            to form a reasoned judgment concerning the matters before them, and
            the Information Circular shall include disclosure of the
            determinations and recommendations of the board of directors of
            Assure set forth in Section 6.1(u);

      (m)   Assure will take, or cause to be taken, all action and to do, or
            cause to be done, all other things necessary, proper or advisable
            under applicable laws and regulations to complete the Arrangement,
            including using reasonable commercial efforts:

            (i)   to obtain all necessary waivers, consents and approvals
                  required to be obtained by it from other parties to loan
                  agreements, leases and other contracts;

            (ii)  to obtain all necessary consents, approvals and authorizations
                  as are required to be obtained by it under any Canadian or
                  foreign law or regulation;

            (iii) to effect all necessary registrations and filings with, and
                  submissions of information requested by, governmental
                  authorities required to be effected by it in connection with
                  the Arrangement;

            and Assure will use its reasonable commercial efforts to cooperate
            with GEOCAN in connection with the performance by it of its
            obligations under Section 8.1(c), including, without limitation,
            continuing to provide reasonable access to information and to
            maintain ongoing communications as between officers of Assure and
            GEOCAN, subject in all respects to the Confidentiality Agreement;

      (n)   Assure will conduct its affairs so that all of Assure's
            representations and warranties contained herein, insofar as the
            accuracy of such representations and warranties constitute a
            condition of closing under subsection 4.1(a), shall be true and
            correct on and as of the Effective Date as if made thereon;

      (o)   Assure shall promptly notify GEOCAN in writing of any material
            change (actual, anticipated, contemplated or, to the knowledge of
            Assure, threatened, financial or otherwise) in the business,
            operations, affairs, assets, capitalization, financial condition,
            prospects, licences, permits, rights, privileges or liabilities,
            whether contractual or otherwise, of Assure and the Assure
            Subsidiaries, taken as a whole, or of any change in any
            representation or warranty provided by Assure in this Agreement
            which change is or may be of such a nature to render any
            representation or warranty misleading or untrue in any material
            respect and Assure shall in good faith discuss with GEOCAN any
            change in circumstances (actual, anticipated, contemplated, or to
            the knowledge of Assure threatened) which is of such a nature that
            there may be a reasonable question as to whether notice needs to be
            given to GEOCAN pursuant to this provision;


                                       29


      (p)   Assure will, within two Business Days of Assure receiving any
            written audit inquiry, assessment, reassessment, confirmation or
            variation of an assessment, indication that tax assessment is being
            considered, request for filing of a waiver or extension of time or
            any other notice in writing relating to taxes, interest, penalties,
            losses or tax pools (an "Assessment"), deliver to GEOCAN a copy
            thereof together with a statement setting out, to the extent then
            determinable, an estimate of the obligations, if any, of Assure on
            the assumption that such Assessment is valid and binding;

      (q)   Assure shall promptly advise GEOCAN of the number of Assure Shares
            and Assure Warrants for which Assure receives notices of dissent or
            written objections to the Arrangement and provide GEOCAN with copies
            of such notices and written objections;

      (r)   Assure shall use all reasonable efforts to obtain releases in favour
            of Assure and GEOCAN from Assure's employees who are not directors
            and officers similar to those contemplated by Section 4.1(g) hereof;

      (s)   Assure shall use its reasonable commercial efforts to divest its 39%
            holding in Keantha Holdings Inc. before the Effective Date under
            commercial terms acceptable to GEOCAN and, pending such disposition,
            shall use its reasonable commercial efforts to ensure that there is
            no material decrease in or disposition of the assets (including cash
            and the airplane) or any material increase in the liabilities of
            Keantha Holdings;

      (t)   Assure shall use its reasonable commercial efforts to (i) cause the
            holder of the Assure PP A Warrants to accept a change in its expiry
            from July 1, 2007 to May 31, 2006, (ii) cause holders of the Assure
            Other Warrants to surrender such warrants to Assure for nominal
            consideration, (iii) cause the holders of the Assure Preferred
            Shares to execute the Assure Preferred Shares Waiver, and (iv) in
            any event cause all holders of Assure Warrants to vote in favour of
            the Plan of Arrangement;

      (u)   all information in the Information Circular (other than information
            relating to and supplied by GEOCAN) shall be true and complete in
            all material respects and shall not contain any misrepresentation;

      (v)   prior to the Effective Date Assure and each Assure Subsidiary will
            not implement any shareholder rights plan or any other form of plan,
            agreement, contract or instrument that will trigger any rights to
            acquire Assure Shares or other securities of Assure or any Assure
            Subsidiary or rights, entitlements or privileges in favour of any
            person upon the entering into of this Agreement or on the
            Arrangement becoming effective;

      (w)   prior to the Effective Date, Assure shall provide GEOCAN with
            auditor reviewed financial statements for Assure's first fiscal
            quarter of 2005 and prior to the Effective Date, Assure shall use
            reasonable commercial efforts to provide GEOCAN with auditor
            reviewed financial statements for Assure's second fiscal quarter of
            2005;

      (x)   Assure shall offer and shall use its reasonable commercial efforts
            to cause the holders of Assure A Warrants and Assure B Warrants to
            accept prior to the Effective Date the exchange of Assure A Warrants
            for Assure Shares on the basis of 0.77 Assure Shares for each Assure
            A Warrant and the exchange of Assure B Warrants on the basis of 0.44
            Assure Shares for each Assure B Warrant and, in any event shall
            ensure that, at the Effective Date no more than 500,000 Assure A
            Warrants and no more than 1,200,000 Assure B Warrants remain
            outstanding;


                                       30


      (y)   Assure shall use its reasonable efforts to cause holders of Assure
            warrants, other than Assure A Warrants and Assure B Warrants, to
            surrender such Assure Warrants for cancellation; and

      (z)   Assure shall provide the constating documents, bylaws, minute books
            and securities registers and current and historical financial
            statements of Keantha Holdings Inc. to GEOCAN for review as soon as
            practicable and in any event prior to the Effective Date.

9.2   (a)   Assure shall immediately cease and cause to be terminated all
            solicitations, initiations, encouragements, discussions or
            negotiations, if any, with any persons conducted before the date of
            this Agreement with respect to any Assure Acquisition Proposal and
            shall immediately request the return or destruction of all
            information provided to third parties, if any, who have entered into
            a confidentiality agreement with Assure relating to an Assure
            Acquisition Proposal and shall use all reasonable commercial efforts
            to ensure that such requests are honoured.

      (b)   Assure shall not, directly or indirectly, authorize or permit any of
            the officers, directors or employees of Assure or of any financial
            advisor, expert or other person acting on its behalf to:

            (i)   solicit, initiate or encourage (including, without limitation,
                  by way of furnishing information or entering into any form of
                  agreement, arrangement or understanding) a Assure Acquisition
                  Proposal;

            (ii)  enter into or participate in any discussions on negotiations
                  regarding a Assure Acquisition Proposal, or, except in the
                  ordinary course of business, furnish to any other person any
                  information with respect to the business, properties,
                  operations, prospects or conditions (financial or otherwise)
                  of Assure or a Assure Acquisition Proposal or otherwise
                  cooperate in any way with, or assist or participate in,
                  facilitate or encourage, any effort or attempt of any other
                  person to do or seek to do any of the foregoing; or

            (iii) waive, or otherwise forbear (except in respect of non material
                  matters) in the enforcement of, or enter into or participate
                  in any discussions, negotiations or agreements to waive or
                  otherwise forbear in respect of, any rights or other benefits
                  of Assure under confidential information agreements,
                  including, without limitation, any "standstill provisions"
                  thereunder;

            provided, however, that notwithstanding any other provisions hereof,
            Assure (and its directors, officers, employees and advisors) may:

            (iv)  engage in discussions or negotiations with a third party who
                  (without any solicitation, initiation or encouragement,
                  directly or indirectly, by Assure or any of the officers,
                  directors or employees of Assure or any financial advisor,
                  expert or other representative or agent acting on its behalf)
                  seeks to initiate such discussions or negotiations and,
                  subject to execution of a confidentiality agreement
                  substantially similar to the Confidentiality Agreement, may
                  furnish such third party information concerning Assure and its
                  business, properties and assets, in each case if, and only to
                  the extent that:

                  (A)   the third party has first made a written bona fide
                        Assure Acquisition Proposal that is a Assure Superior
                        Proposal; and

                  (B)   prior to furnishing such information to or entering into
                        discussions or negotiations with such third party,
                        Assure provides prompt notice to GEOCAN to the effect
                        that it is furnishing information to or entering into
                        discussions or negotiations with such third party
                        together with a copy of the confidentiality agreement
                        referenced above and if not previously provided to
                        GEOCAN, copies of all information provided to such third
                        party are provided to GEOCAN concurrently with the
                        provision of such information to such third party.
                        Assure shall immediately notify GEOCAN orally and in
                        writing of any inquiries, offers or proposals with
                        respect to any Assure Acquisition Proposal (including
                        without limitation, the terms and conditions of any such
                        proposal (and any amendments or changes thereto), the
                        identity of the person making it, and if not previously
                        provided to GEOCAN, copies of all information provided
                        to such person and all other information reasonably
                        requested by GEOCAN), shall keep GEOCAN informed of the
                        status and details of any such inquiry, offer or
                        proposal and answer GEOCAN's questions with respect
                        thereto.


                                       31


      (c)   Assure shall give GEOCAN 48 hours advance notice of any agreement
            (and the terms of such agreement) to be entered into with, or any
            information to be supplied to, any person making an inquiry, offer
            or proposal with respect to a Assure Superior Proposal and shall
            confirm the determination of Assure's board of directors that the
            Assure Acquisition Proposal is a Assure Superior Proposal. For a
            period of 48 hours from the time that Assure provides notice of such
            Assure Superior Proposal to GEOCAN and any amendment thereto,
            together with the foregoing confirmation in respect of the board of
            directors' determination, the board of directors of Assure and
            Assure agree not to accept, recommend or approve or enter into any
            agreement (an "Assure Proposed Agreement") to implement such a
            Assure Superior Proposal or release the party from making the Assure
            Superior Proposal from any standstill provisions. In addition, in
            respect of any Assure Superior Proposal, Assure shall and shall
            cause its financial and legal advisors to negotiate in good faith
            with GEOCAN to make such adjustments in the terms and conditions of
            this Agreement and the terms of the Arrangement as would enable
            Assure to proceed with the transaction contemplated herein, as
            amended, rather than the Assure Superior Proposal. In the event that
            GEOCAN proposes to and does amend this Agreement and the terms of
            the Arrangement to provide equal or superior value to that provided
            under the Assure Superior Proposal within a period of 48 hours from
            the time that GEOCAN receives notice of the Assure Superior Proposal
            and a copy of the Assure Proposed Agreement (and any amendments
            thereto), Assure shall not enter into any Assure Proposed Agreement
            regarding the Assure Superior Proposal or any amendment thereof.

      (d)   Notwithstanding Section 6.1(u) in the event that, prior to the
            completion of the Arrangement, a Assure Superior Proposal is offered
            or made to the holders of Assure Shares or Assure, the board of
            directors of Assure may fail to make, withdraw, modify or change any
            recommendation regarding the Arrangement if, in the opinion of the
            board of directors acting in good faith after written advice from
            outside counsel to such effect, which is reflected in the minutes of
            a meeting of the board of directors of Assure (a copy of the
            relevant extract of which minutes shall be provided to GEOCAN), the
            making or failure to so withdraw, modify or change any
            recommendation regarding the Arrangement would be inconsistent with
            the performance by the directors of Assure of their fiduciary duties
            under applicable law, and provided Assure shall have complied with
            the provisions of Section 9.3 and paid the GEOCAN Break Fee to
            GEOCAN in the circumstances where such fee is payable.

9.3   Subject to Section 10.4, if at any time after the date of this Agreement:

      (a)   the board of directors of Assure fails to recommend that the Assure
            Securityholders approve the Arrangement or withdraws or, in any
            manner adverse to GEOCAN redefines, modifies or changes any of its
            recommendations referred to in Section 6(u), unless it has the right
            to do so under Section 9.4 hereof; or

      (b)   prior to the date of the Assure Meeting:

            (i)   a Assure Acquisition Proposal that is a Assure Superior
                  Proposal is publicly announced or made to Assure or Assure's
                  shareholders;

            (ii)  the Assure Superior Proposal has not been withdrawn or
                  expired; and

                  (A)   the board of directors of Assure fails to confirm to the
                        Assure Shareholders, within five business days after the
                        making of the Assure Proposal its recommendation that
                        the Assure Shareholders reject the Assure Superior
                        Proposal; or


                                       32


                  (B)   Assure enters into an agreement (other than a
                        confidentiality agreement) with respect to the Assure
                        Superior Proposal;

                  and the Arrangement is not approved at the Assure Meeting; or

      (c)   Assure shall have breached, or failed to comply with, in any
            material respect, any of its covenants or other obligations under
            this Agreement or any of the representations and warranties of
            Assure contained in this Agreement shall not be true and correct in
            all material respects as of the date of this Agreement, except where
            the failure of such representations and warranties to be true and
            correct would not have a Material Adverse Effect on Assure, or shall
            have ceased to be true and correct in any material respect
            thereafter, except where the failure of such representations and
            warranties to be true and correct would not have a Material Adverse
            Effect on Assure, (other than, in either case, as a direct result of
            and in direct response to a breach by GEOCAN of its obligations
            under this Agreement);

      then Assure shall, within two business days after the first to occur of
      the events described above, pay to GEOCAN the GEOCAN Break Fee. Such
      payment shall be made in immediately available funds to an account
      designated by GEOCAN. The payment of the GEOCAN Break Fee to GEOCAN shall

      further remedy or recourse in respect of such matter against Assure or its
      present or former directors, officers, employers, agents or advisors or
      Assure's counsel.

9.4   The board of directors of Assure reserves the right to not make, withdraw,
      redefine, modify or change its recommendations or its determinations
      referred to in Section 6.1(u) if any of the following occur on or prior to
      the Effective Date:

      (a)   GEOCAN shall have breached, or failed to comply with, in any
            material respect, any of its covenants or other obligations under
            this Agreement;

      (b)   any of the representations and warranties of GEOCAN contained in
            this Agreement shall not be true and correct in all material
            respects as of the date of this Agreement or shall have ceased to be
            true and correct in any material respect thereafter (other than as a
            result of a breach of this Agreement by Assure or of the Lockup
            Agreements by any of the holders of the Assure Shares, Assure
            Options or Assure Warrants); or

      (c)   it becomes certain that any of the conditions contained in Sections
            3.1 or 5.1 will not be satisfied on or before the Effective Date
            (other than as a result of a breach of this Agreement by Assure or
            of the Lockup Agreements by any of the holders of the Assure Shares,
            Assure Options or Assure Warrants who execute and deliver Lockup
            Agreements) and all relevant parties do not agree to waive or modify
            such conditions.

9.5   Assure shall use its reasonable efforts to cause all persons holding
      Assure Options or Assure Warrants, other than directors and officers of
      Assure, to exercise those Assure Options or Assure Warrants prior to the
      Assure Meeting and to vote the Assure Shares acquired on exercise in
      favour of the Arrangement, all in accordance with the terms of the Lockup
      Agreements. Assure shall also use its reasonable efforts to ensure that
      all Assure Shares acquired on exercise of the Assure Options or Assure
      Warrants at any time prior to the Assure Meeting, be made eligible for
      voting at the Assure Meeting, subject to all applicable law.

            unacceptable to Assure, acting reasonably, on appeal or otherwise;

      (d)   if the Arrangement has not been completed on or before October 6,

      (e)   if a circumstance giving rise to the payment of the Assure Break Fee
            to Assure shall have occurred;

      (f)   if a circumstance giving rise to payment of the GEOCAN Break Fee to
            GEOCAN shall have occurred and such payment shall have been made; or

      (g)   upon any other circumstances hereunder that give rise to a
            termination of this agreement by Assure, including those set forth
            in Sections 3.1 and 5.1 hereof.

10.4  (a)   Each of GEOCAN and Assure will give prompt notice to the other of
            the occurrence, or failure to occur, at any time from the date
            hereof until the Effective Date, of any event or state of facts
            which occurrence or failure would, or would likely to:

            (i)   cause any of the representations or warranties of either
                  GEOCAN or Assure contained herein to be untrue or inaccurate
                  in any material respect on the date hereof or on the Effective
                  Date; or


                                       34


            (ii)  result in the failure to comply with or satisfy any covenant,
                  condition or agreement to be complied with or satisfied, in
                  any material respect, by either GEOCAN or Assure hereunder on
                  or prior to the Effective Date.

      (b)   Subject to Section 10.4(c), neither GEOCAN nor Assure may elect not
            to complete the transactions contemplated hereby pursuant to the
            non-fulfillment of the conditions precedent contained in Articles 3,
            4 or 5 or pursuant to Section 10.2 or 10.3 or any termination right
            arising therefrom and no payments are payable pursuant to Section
            8.2 or 9.3 as a result of such election unless promptly and in any
            event prior to the filing of the articles of Arrangement for
            acceptance by the Registrar, the party intending to rely thereon has
            delivered a written notice (a "Default Notice") to the other party
            specifying in reasonable detail all breaches, in any material
            respect, of covenants, representations and warranties or other
            matters which the party delivering such notice is asserting as the
            basis for the non-fulfillment of the applicable condition precedent
            or termination right, as the case may be.

      (c)   Nothing in this Section 10.4 shall effect, and no Default Notice
            shall be required in respect of, (i) the right of GEOCAN to receive
            payment of the GEOCAN Break Fee pursuant to Section 9.3 (a) or (b),
            or (ii) the right of either party to terminate this Agreement for
            matters arising out of the failure to make appropriate disclosure In
            Writing to the other party.

      (d)   If any such Default Notice is delivered, provided that the affected
            party is proceeding diligently to cure such matter and such matter
            is capable of being cured neither party may terminate this Agreement
            (if they otherwise have the right to do so) until expiration of a
            period of twenty (20) days from such Default Notice and then only if
            such matter is not cured in all material respects. If such Default
            Notice has been delivered prior to the date of the Assure Meeting,
            such meeting shall be postponed until the expiry of such period. If
            such Default Notice has been delivered prior to the making of the
            application for the Final Order or the filing of the Articles of
            Arrangement with the Registrar, such application and such filing
            shall be postponed until the expiry of such period.

      (e)   Nothing in this Section 10.4 shall give either GEOCAN or Assure, as
            the case may be, any right to terminate this Agreement in addition
            to the rights contained in Articles 3, 4 or 5 or pursuant to Section
            10.2 or 10.3 or any termination right arising therefrom or any right
            to receive payment of the Assure Break Fee or GEOCAN Break Fee
            except in the circumstances provided in Sections 8.2 and 9.3.

10.5  If this Agreement is validly terminated pursuant to any provision of this
      Agreement, the parties shall return all materials and copies of all
      materials delivered to Assure or GEOCAN, as the case may be, or their
      agents and, except for the obligations set forth in Sections 8.2, 9.3, and
      this 10.4 and Article 11 (which shall survive any termination of this
      Agreement and continue in full force and effect), no party shall have any
      further obligations to any other party hereunder with respect to this
      Agreement except those incurred prior to termination. Except as expressly
      provided herein, nothing herein, (including without limitation the payment
      of the GEOCAN Break Fee or the Assure Break Fee) shall relieve any party
      from liability for any breach of this Agreement.

10.6  The exercise by any party of any right of termination hereunder shall be
      without prejudice to any other remedy available to such party.

                                   ARTICLE 11
